(1) This Registration Statement relates to the Common Stock, par value $2.50 per
    share (the "AIG Common Stock"), of the Registrant issuable to holders of the
    Common Stock, par value $1.00 per share (the "Common Stock"), of American
    Bankers and the $3.125 Cumulative Convertible Serial Preferred Stock, Series
    C, par value $5.00 per share (the "AIG Series C Preferred Stock") of the
    Registrant issuable to holders of the $3.125 Series B Cumulative Convertible
    Preferred Stock, no par value (the "Preferred Stock") of American Bankers in
    connection with the Merger.
(2) The number of shares to be registered pursuant to this Registration
    Statement is based on the maximum number of shares of AIG Common Stock and
    AIG Series C Preferred Stock issuable to shareholders of American Bankers in
    the Merger at an assumed maximum exchange ratio of (i) .4495 of a share of
    AIG Common Stock in exchange for each share of Common Stock (assuming that
    all shares of Common Stock are exchanged only for AIG Common Stock) and (ii)
    one share of AIG Series C Preferred Stock in exchange for each share of
    Preferred Stock, and assuming that the maximum number of shares of Common
    Stock to be acquired in the Merger for AIG Common Stock is 42,205,238 and
    the maximum number of shares of Preferred Stock to be acquired in the Merger
    for AIG Series C Preferred Stock is 2,300,000.
(3) Estimated solely for the purpose of calculating the registration fee
    pursuant to Rule 457(c) of the Securities Act of 1933, as amended (the
    "Securities Act"), based on the product of the estimated maximum number of
    shares of Common Stock to be acquired in the Merger (42,205,238) multiplied
    by $46.0625, the average of the high and low prices of Common Stock on
    January 23, 1998, as reported on the New York Stock Exchange, plus the
    product of the estimated maximum number of shares of Preferred Stock to be
    acquired in the Merger (2,300,000) multiplied by $94.50, the average of the
    high and low prices of Preferred Stock on January 23, 1998, as reported on
    the New York Stock Exchange.
 
(4) Calculated by multiplying .000295 by the proposed maximum aggregate offering
    price. $421,059.44 of such amount is offset pursuant to Rule 457 by fees
    previously paid.
 
   THE REGISTRANT HEREBY AMENDS THIS REGISTRATION STATEMENT ON SUCH DATE OR
DATES AS MAY BE NECESSARY TO DELAY ITS EFFECTIVE DATE UNTIL THE REGISTRANT SHALL
FILE A FURTHER AMENDMENT WHICH SPECIFICALLY STATES THAT THIS REGISTRATION
STATEMENT SHALL THEREAFTER BECOME EFFECTIVE IN ACCORDANCE WITH SECTION 8(A) OF
THE SECURITIES ACT OR UNTIL THE REGISTRATION STATEMENT SHALL BECOME EFFECTIVE ON
SUCH DATE AS THE COMMISSION, ACTING PURSUANT TO SAID SECTION 8(A), MAY
DETERMINE.

                                                                January 30, 1998
 
Dear Fellow Shareholder:
 
     You are cordially invited to attend a special meeting of the shareholders
of American Bankers Insurance Group, Inc. The special meeting of the holders of
$3.125 Series B Cumulative Convertible Preferred Stock will be held on March 4,
1998 at 10:00 A.M., Eastern time, at the Auditorium of the Company's
Headquarters, 11222 Quail Roost Drive, Miami, Florida 33157-6596. The special
meeting of the holders of Common Stock will be held on March 6, 1998 at 10:00
A.M., Eastern time, at the Auditorium of the Company's Headquarters, 11222 Quail
Roost Drive, Miami, Florida 33157-6596. At the special meetings you will be
asked to approve a merger pursuant to which:
 
     - American Bankers will become a wholly-owned subsidiary of American
       International Group, Inc.;
 
     - each share of Series B Preferred Stock will be converted into one share
       of AIG Cumulative Convertible Serial Preferred Stock, Series C which will
       contain terms substantially similar to the terms of the Series B
       Preferred Stock (after making appropriate conversion adjustments) and
       will be convertible into AIG Common Stock; and
 
     - each outstanding share of Common Stock will be converted, at the election
       of the holder, but subject to certain limitations, into $47.00 in cash,
       AIG Common Stock with a value equal to $47.00 (based on a specific ten
       day averaging period for AIG Common Stock), or a combination of cash and
       AIG Common Stock with a value equal to $47.00, as discussed more fully in
       the enclosed Proxy Statement/Prospectus, which you are urged to read
       carefully.
 
     The Board of Directors believes the merger will allow American Bankers to
enjoy opportunities for operating efficiencies and synergies, particularly in
the international distribution of American Bankers' products. American Bankers
shareholders will have the opportunity to participate in these synergies
following the merger as shareholders of American International Group, Inc.
 
     The Board of Directors has received a written opinion of Salomon Smith
Barney to the effect that, based upon and subject to the matters set forth in
the opinion, the consideration to be received by the holders of Series B
Preferred Stock and Common Stock pursuant to the merger is fair, from a
financial point of view, to the American Bankers shareholders (including holders
of both Series B Preferred Stock and Common Stock).
 
     THE BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT, HAS
DETERMINED THAT THE MERGER IS FAIR TO, AND IN THE BEST INTERESTS OF, AMERICAN
BANKERS AND ITS SHAREHOLDERS (INCLUDING HOLDERS OF BOTH SERIES B PREFERRED STOCK
AND COMMON STOCK) AND RECOMMENDS THAT HOLDERS OF SERIES B PREFERRED STOCK AND
COMMON STOCK VOTE FOR APPROVAL AND ADOPTION OF THE MERGER AGREEMENT AND THE
MERGER.
 
     YOUR VOTE IS IMPORTANT. To assure your representation at the special
meeting applicable to you, please complete, sign and date the enclosed proxy
card and return it in the enclosed white prepaid envelope marked "Proxy". This
will allow your shares to be voted whether or not you attend the meeting.
 
     Holders of Series B Preferred Stock should not send their stock
certificates with their proxy cards. Holders of Common Stock wishing to make a
Cash Election or Stock Election, as described in this Proxy
Statement/Prospectus, should send in their stock certificates along with the
enclosed Election Form properly completed in the enclosed brown envelope marked
"Election Form". An election to receive cash or stock in the Merger will not
constitute a vote in favor of approval of the Merger.
 
                                          Sincerely yours,
 
                                          [/s/ R. Kirk Landon]

                                ABOUT THE MERGER
 
     This summary highlights certain information from this document, is
qualified by reference thereto and may not contain all of the information that
is important to you. To understand the Merger more fully and for a more complete
description of the legal terms of the Merger, you should read carefully this
entire document, the documents referred to in the "Incorporation of Certain
Documents by Reference" section at the beginning of this document and the
Appendices hereto. The summary does not contain a complete statement of material
information relating to the Merger Agreement, the Merger, or other matters
discussed in this document.
 
Q:  WHY IS AMERICAN BANKERS PROPOSING TO MERGE WITH AIG?
 
A:  The American Bankers Board determined to recommend approval of the Merger
    Agreement and the Merger based on a wide variety of factors, including:
 
    - American Bankers' historical growth and the capital requirements which
      would be needed to sustain a similar level of growth in the future;
 
    - potential synergies in connection with the Merger;
 
    - AIG's historical financial performance, international experience and its
      depth of knowledge and experience in regulatory matters;
 
    - the terms and provisions of the Merger Agreement and related agreements;
 
    - the fairness opinion of American Bankers' financial advisor, Salomon Smith
      Barney; and
 
    - historical market prices and recent trading activity of the Common Stock.
 
    The American Bankers Board also considered certain countervailing factors
    such as AIG's historically high price/earnings ratio and the possible effect
    of the recent turmoil in the financial markets in Asia on AIG.
 
Q:  WHAT DO I NEED TO DO NOW?
 
A:  After you have carefully read this Proxy Statement/Prospectus, just indicate
    on your proxy card how you want to vote, and sign and mail it in the
    enclosed white prepaid return envelope marked "Proxy" as soon as possible,
    so that your shares of Preferred Stock and/or Common Stock may be
    represented at the Preferred Shareholders Special Meeting or the Common
    Shareholders Special Meeting, as the case may be. The Preferred Shareholders
    Special Meeting will take place on March 4, 1998 at 10:00 a.m., Eastern
    time, at the Auditorium of the Company's Headquarters, 11222 Quail Roost
    Drive, Miami, Florida 33157-6596. The Common Shareholders Special Meeting
    will take place on March 6, 1998 at 10:00 a.m., Eastern time, at the
    Auditorium of the Company's Headquarters, 11222 Quail Roost Drive, Miami,
    Florida 33157-6596. The American Bankers Board unanimously recommends voting
    IN FAVOR OF the proposed Merger.
 
    If you are a holder of Common Stock, also complete, sign and mail the
    Election Form in the enclosed brown return envelope marked "Election Form"
    as soon as possible, in order to indicate whether you prefer to receive cash
    or AIG Common Stock in the Merger for all or any part of your shares of
    Common Stock. In order to be effective, Election Forms must be submitted to
    the exchange agent listed on the return envelope no later than 5:00 p.m. New
    York City time on the third trading day prior to the date of the
    consummation of the Merger (the "Election Deadline") and must be accompanied
    by the certificates representing the shares of Common Stock for which the
    election is being made or an appropriate guarantee of delivery by a
    commercial bank or trust company in the United States or a member of a
    registered national securities exchange or the National Association of
    Securities Dealers, Inc. The Election Deadline will not occur any earlier
    than 5:00 p.m., New York City time, on March 3, 1998. AIG will publicly
    announce the Election Deadline not later than 10:00 a.m. on the trading day
    preceding the date on which the Election Deadline occurs. Holders who fail
    to submit an effective Election Form will be treated as non-electing
    shareholders.
 
    If you are a participant in the American Bankers Leveraged Employee Stock
    Option Plan, please read carefully the accompanying letter from the Company.
    Plan participants will receive their proxy cards and Election Forms by

<PAGE>   10
 
    mail shortly. They are NOT included with this Proxy Statement/Prospectus.
 
Q:  WHY ARE THE PREFERRED SHAREHOLDERS SPECIAL MEETING AND THE COMMON
    SHAREHOLDERS SPECIAL MEETING BEING HELD AT SEPARATE TIMES?
 
A:  The Merger Agreement must be approved by both the holders of a majority of
    the outstanding shares of Preferred Stock and the holders of a majority of
    the outstanding shares of Common Stock, each voting as a separate class. The
    Preferred Shareholders Special Meeting has been scheduled to be held prior
    to the Common Shareholders Special Meeting so that the holders of Common
    Stock will know the result of the vote of the holders of Preferred Stock
    prior to the Common Shareholders Special Meeting. As soon as practicable
    following the Preferred Shareholders Special Meeting, American Bankers will
    publicly announce by means of a press release the results of the vote at
    that meeting, and, if the Merger Agreement is not approved by the requisite
    vote of the holders of Preferred Stock, will file with the Commission and
    mail to the holders of Common Stock a supplement to this Proxy
    Statement/Prospectus which contains the results.
 
    In the event that the Merger Agreement is not approved by the requisite vote
    of the holders of Preferred Stock, the Common Shareholders Special Meeting
    will be postponed to a later date to enable the holders of Common Stock to
    evaluate the information contained in the supplement. In addition, the
    Merger Agreement provides that if the holders of a majority of the
    outstanding shares of Preferred Stock do not approve the Merger Agreement,
    the proposed transaction will be restructured without any further action,
    including any action by the American Bankers Board. The transaction as
    restructured would not require the approval of the holders of Preferred
    Stock. It would also be fully taxable to holders of Common Stock.
 
Q:  IF MY SHARES ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER VOTE MY
    SHARES FOR ME?
 
A:  Your broker will vote your shares only if you provide instructions on how to
    vote. You should follow the directions provided by your broker regarding how
    to instruct your broker to vote your shares. Without instructions, your
    shares will not be voted, which for purposes of voting on the proposed
    Merger will have the same effect as voting against the proposed Merger.
 
Q:  CAN I CHANGE MY VOTE AFTER I HAVE MAILED MY SIGNED PROXY CARD?
 
A:  Yes. You can change your vote at any time before your proxy is voted at the
    Preferred Shareholders Special Meeting or Common Shareholders Special
    Meeting, as applicable. You can do this in one of three ways. First, you can
    send a written notice stating that you would like to revoke your proxy.
    Second, you can complete and submit a new proxy card. If you choose either
    of these two methods, you must submit your notice of revocation or your new
    proxy card to American Bankers at the address on page 4. Third, you can
    attend the Preferred Shareholders Special Meeting or Common Shareholders
    Special Meeting, as applicable, and vote in person. Simply attending the
    meeting, however, will not revoke your proxy. If you have instructed a
    broker to vote your shares, you must follow directions received from your
    broker to change your vote.
 
Q:  CAN I CHANGE MY ELECTION AFTER I HAVE MAILED MY SIGNED ELECTION FORM?
 
A:  Yes. You can change your election at any time before the Election Deadline
    by submitting a written notice of revocation or a later dated Election Form
    to the exchange agent.
 
Q:  SHOULD I SEND IN MY STOCK CERTIFICATES WHEN I RETURN MY ELECTION FORM?
 
A:  For holders of Common Stock, yes. An Election Form will not be effective
    unless accompanied by certificates representing the shares of Common Stock
    for which the election is being made or an appropriate guarantee of delivery
    by a commercial bank or trust company in the United States or a member of a
    registered national securities exchange or the National Association of
    Securities Dealers, Inc. ChaseMellon Shareholder Services L.L.C., the
    Exchange Agent, will hold the certificates on your behalf. If for any reason
    the Merger is not consummated, your certificates will be returned to you.

<PAGE>   11
 
    Holders of Preferred Stock should not send in their stock certificates now.
 
Q:  WHAT WILL HOLDERS OF PREFERRED STOCK RECEIVE IN THE MERGER?
 
A:  Holders of Preferred Stock will receive one share of AIG Series C Preferred
    Stock in exchange for each share of Preferred Stock. The AIG Series C
    Preferred Stock will be governed by terms substantially similar to the terms
    of the Preferred Stock (after making appropriate conversion adjustments) and
    will be convertible into AIG Common Stock.
 
Q:  WHAT WILL HOLDERS OF COMMON STOCK RECEIVE IN THE MERGER?
 
A:  Subject to the limitation set forth below, holders of Common Stock that
    elect to receive cash will receive $47.00 in cash in exchange for each share
    of Common Stock. The maximum aggregate amount of cash that AIG will pay to
    holders of Common Stock will be equal to 49.9% of the total value of the
    consideration paid to all holders of Common Stock in connection with the
    Merger (the "Maximum Cash Pool"). If cash elections are made with respect to
    more than 49.9% of the outstanding shares of Common Stock, AIG will make
    cash payments on a pro rata basis to holders that elect to receive cash so
    that the total amount of cash paid equals the Maximum Cash Pool. The
    remaining consideration paid to holders of Common Stock that elect to
    receive cash will be in the form of AIG Common Stock.
 
    Subject to AIG's election described below, holders of Common Stock that make
    no election ("non-electing shareholders") or that elect to receive AIG
    Common Stock will receive a portion of a share of AIG Common Stock with a
    value equal to $47.00 (as determined based on the average of the closing
    prices per share of AIG Common Stock on the NYSE for the ten trading days
    ending on the third trading day prior to the date that the Merger is
    consummated, the "Base Period Stock Price") in exchange for each share of
    Common Stock. If the Base Period Stock Price is less than $104.5625 and cash
    elections have been made with respect to less than 49.9% of the outstanding
    shares of Common Stock, AIG will be entitled, at its election and subject to
    the limitations set forth below, to pay in cash a portion of the
    consideration to be received by holders of Common Stock that elect to
    receive AIG Common Stock or that make no election. The maximum amount of
    cash that AIG may elect to pay such holders per share of Common Stock will
    be equal to $47.00 minus the product of .4495 and the Base Period Stock
    Price (the "Per Share Cash Top-Up Amount"). In addition, the maximum
    aggregate amount of cash that AIG may pay to all non-electing shareholders
    will be equal to the Maximum Cash Pool minus the aggregate amount of cash
    paid to holders of Common Stock that elect to receive cash. The maximum
    aggregate amount of cash that AIG may pay to holders of Common Stock that
    elect to receive AIG Common Stock will be equal to the lesser of (i) the
    Maximum Cash Pool or (ii) the product of the number of shares of Common
    Stock outstanding upon consummation of the Merger and the Per Share Cash
    Top-Up Amount, in each case minus the aggregate amount of cash paid to
    holders of Common Stock that elect to receive cash or that make no election.
 
Q:  WHEN DO YOU EXPECT THE MERGER TO BE COMPLETED?
 
A:  We are working towards completing the Merger as quickly as possible. In
    addition to the approvals of the holders of Preferred Stock and Common
    Stock, we must also obtain certain insurance and other regulatory approvals
    that are expected to be obtained following the Common Shareholders Special
    Meeting. We expect to complete the Merger during March 1998.
 
Q:  WHAT ARE THE TAX CONSEQUENCES OF THE MERGER?
 
A:  The Merger generally will not cause federal income tax to be imposed on
    holders of Preferred Stock. In addition, the Merger generally will not cause
    federal income tax to be imposed on holders of Common Stock to the extent
    such holders receive AIG Common Stock. Holders of Common Stock generally
    will have to pay federal income taxes on any cash received by such holders
    to the extent of any gain they may have on their Common Stock. In general,
    such gain will be capital gain. To review the tax consequences to
    shareholders in greater detail, see page 32. If, however, the
 
                                        3

<PAGE>   12
 
    Merger is restructured because the holders of Preferred Stock do not approve
    the Merger, holders of Common Stock generally will have to pay federal
    income taxes on any gain they may have on their Common Stock, even if they
    receive only AIG Common Stock in the Merger. There will be no immediate
    federal income tax consequences to holders of Preferred Stock in such a
    circumstance, but a later conversion of the Preferred Stock into AIG Common
    Stock would be a taxable transaction. To review in greater detail the
    federal income tax consequences to shareholders if the Merger is so
    restructured, see page 32.
 
Q:  ARE THERE ANY RISKS ASSOCIATED WITH THE MERGER?
 
A:  The Merger does involve risks. For a discussion of certain risk factors that
    should be considered in evaluating the Merger, see "Risk Factors", beginning
    on page 19.
 
Q:  WHAT OTHER MATTERS WILL BE VOTED ON AT THE SPECIAL MEETINGS?
 
A:  We do not expect to ask you to vote on any matter other than the Merger at
    the Preferred Shareholders Special Meeting or the Common Shareholders
    Special Meeting.

     This summary highlights certain information from this document, is
qualified by reference thereto and may not contain all of the information that
is important to you. To understand the Merger more fully and for a more complete
description of the legal terms of the Merger, you should read carefully this
entire document, the documents referred to in the "Incorporation of Certain
Documents by Reference" section at the beginning of this document and the
Appendices hereto. The summary does not contain a complete statement of material
information relating to the Merger Agreement, the Merger, or other matters
discussed in this document.
 
THE COMPANIES
 
American International Group, Inc.
70 Pine Street
New York, New York 10270
212-770-7000
 
     AIG is a holding company with a market capitalization, as of December 31,
1997, of approximately $76 billion, which through its subsidiaries is primarily
engaged in a broad range of insurance and insurance-related activities and
financial services in the United States and abroad. AIG's primary activities
include both general and life insurance operations.
 
American Bankers Insurance Group, Inc.
11222 Quail Roost Drive
Miami, Florida 33157-6596
305-253-2244
 
     American Bankers is a specialty insurer providing primarily credit-related
insurance products in the U.S. and Canada as well as in Latin America, the
Caribbean and the United Kingdom. The majority of American Bankers' gross
collected premiums are derived from credit-related insurance products sold
through financial institutions and other entities which provide consumer
financing as a regular part of their businesses.
 
REASONS FOR THE MERGER
 
     The American Bankers Board determined to recommend approval and adoption of
the Merger Agreement and the Merger based on a wide variety of factors,
including American Bankers' historical growth and the capital requirements which
would be needed to sustain a similar level of growth in the future, potential
synergies in connection with the Merger, AIG's international experience and its
depth of knowledge and experience in regulatory matters, the terms and
provisions of the Merger Agreement and related agreements, the opinion of
American Bankers' financial advisor, Salomon Smith Barney, historical market
prices and recent trading activity of the Common Stock, and certain
countervailing factors such as AIG's historically high price/earnings ratio and
the possible effect of the recent turmoil in the financial markets in Asia on
AIG. See "The Merger -- Reasons for the Merger; Recommendation of the American
Bankers Board."
 
THE SPECIAL MEETINGS
 
     When and where the meetings will be held. The Preferred Shareholders
Special Meeting will be held at 10:00 a.m., Eastern time, on March 4, 1998, at
the Auditorium of the Company's Headquarters, 11222 Quail Roost Drive, Miami,
Florida 33157-6596.
 
     The Common Shareholders Special Meeting will be held at 10:00 a.m., Eastern
time, on March 6, 1998, at the Auditorium of the Company's Headquarters, 11222
Quail Roost Drive, Miami, Florida 33157-6596.
 
     Purposes of the Special Meetings.  At the Special Meetings, holders of
Preferred Stock and Common Stock will be asked to approve the Merger Agreement
and the consummation of the Merger.
 
     Record Date; Voting Power.  Holders of Preferred Stock and Common Stock who
owned shares as of the close of business on January 30, 1998, the Record Date,
are entitled to vote at the Special Meetings.
 
     On the Record Date, there were outstanding 2,300,000 shares of Preferred
Stock allowed to vote at the Preferred Shareholders Special Meeting and
approximately 42,205,238 shares of Common Stock allowed to vote at the Common
Shareholders Special Meeting. Holders of Preferred Stock and Common Stock each
will have one vote at the Preferred Shareholders Special Meeting and Common
Shareholders Special Meeting, respectively, for each share of Preferred Stock or
Common Stock held of record on the Record Date.
 
     Votes Required.  The affirmative vote of the holders of a majority of the
outstanding shares of
 
                                        9

<PAGE>   18
 
Preferred Stock as of the Record Date and a majority of the outstanding shares
of Common Stock as of the Record Date, each voting as a separate class, is
required to approve and adopt the Merger Agreement and the consummation of the
Merger. As of the Record Date, American Bankers' directors and executive
officers and their affiliates as a group beneficially owned no shares of
Preferred Stock that were issued and outstanding as of such date and 4,177,200
shares, or approximately 9.9%, of the shares of Common Stock that were issued
and outstanding as of such date. Each of Messrs. Landon and Gaston who, as of
the Record Date, in the aggregate beneficially owned 3,391,066 shares, or
approximately 8.0%, of the shares of Common Stock, have contractually agreed
with AIG to vote in favor of the Merger Agreement and the consummation of the
Merger and have agreed, if requested by AIG, to execute irrevocable proxies in
connection therewith. See "Related Agreements and Transactions -- Voting
Agreement."
 
     As of the Record Date, there were 6 holders of record of Preferred Stock
and approximately 1,850 holders of record of Common Stock as shown on the
records of American Bankers' transfer agents for shares of such stock. Based on
the 2,300,000 shares of Preferred Stock and approximately 42,205,238 shares of
Common Stock outstanding and entitled to vote on the Record Date, a total of
1,150,001 shares of Preferred Stock and approximately 21,102,620 shares of
Common Stock are required to be voted in favor of the Merger Agreement and the
Merger in order for the Merger to be approved and consummated. Accordingly,
American Bankers' directors, executive officers and their affiliates (i) do not
hold any shares of Preferred Stock and (ii) hold shares of Common Stock
representing approximately 19.8% of the total number of shares of Common Stock
required for approval of the Merger. Holders of approximately 16.0% of the
number of shares of Common Stock required for approval of the Merger have
contractually agreed to vote in favor of the Merger.
 
     Quorum; Abstentions and Broker Non-Votes. The required quorum for both the
Preferred Shareholders Special Meeting and Common Shareholders Special Meeting
is a majority of the shares of Preferred Stock and Common Stock, respectively,
issued and outstanding as of the Record Date. Both abstentions and broker
non-votes will be included in determining the number of shares present and
voting at the Preferred Shareholders Special Meeting and Common Shareholders
Special Meeting for the purpose of determining the presence of a quorum.
Abstentions and broker non-votes will have the same effect as votes against the
Merger Agreement and the consummation of the Merger. THE ACTIONS PROPOSED IN
THIS PROXY STATEMENT/PROSPECTUS ARE NOT MATTERS THAT CAN BE VOTED ON BY BROKERS
HOLDING SHARES FOR BENEFICIAL OWNERS WITHOUT THE OWNERS' SPECIFIC INSTRUCTIONS.
ACCORDINGLY, ALL BENEFICIAL OWNERS OF PREFERRED STOCK AND COMMON STOCK ARE URGED
TO RETURN THE ENCLOSED PROXY CARD MARKED TO INDICATE THEIR VOTES.
 
     Alternative Transaction.  The Merger Agreement provides that if the holders
of the Preferred Stock do not approve the Merger Agreement and the Merger, the
transaction will be restructured, as described below in "The Merger
Agreement -- Alternative Transaction Structure", without any further action,
including any action by the American Bankers Board. The transaction as
restructured would not require the approval of the holders of Preferred Stock,
but would be taxable for federal income tax purposes to holders of Common Stock
to the extent of any gain they may have on their Common Stock even if such
holders receive only AIG Common Stock in the Merger.
 
RECOMMENDATION TO SHAREHOLDERS
 
     The American Bankers Board believes that the Merger is fair to, and in the
best interests of, American Bankers and its shareholders (including holders of
both Preferred Stock and Common Stock), and unanimously recommends that holders
of Preferred Stock and Common Stock vote FOR approval and adoption of the Merger
Agreement and the Merger.
 
     Other Interests of Officers and Directors in the Merger.  In considering
the recommendation of the American Bankers Board with regard to the Merger,
shareholders should be aware that a number of American Bankers officers and
directors have option agreements, employment agreements, severance agreements or
benefit plans that provide them with interests in the Merger that are different
from, and in addition to, the interests of shareholders of American Bankers
generally. See "The Merger -- Interests of Certain Persons in the Merger."
 
     Opinion of Financial Advisor.  In deciding to approve the Merger, the
American Bankers Board considered an opinion from its financial advisor, Salomon
Smith Barney, as to the fairness of the
 
                                       10

<PAGE>   19
 
consideration to be received by holders of Preferred Stock and Common Stock
pursuant to the Merger, as of the date of such opinion. This opinion is attached
as Appendix IV to this Proxy Statement/Prospectus. Shareholders are encouraged
to read this opinion in its entirety.
 
THE MERGER
 
     THE MERGER AGREEMENT IS ATTACHED AS APPENDIX I TO THIS DOCUMENT. THE
AMERICAN BANKERS BOARD ENCOURAGES YOU TO READ THE MERGER AGREEMENT IN ITS
ENTIRETY. IT IS THE LEGAL DOCUMENT GOVERNING THE MERGER.
 
     What American Bankers' Shareholders will receive in the Merger; Stock
Elections.  Holders of Preferred Stock will receive one share of AIG Series C
Preferred Stock in exchange for each share of Preferred Stock. The AIG Series C
Preferred Stock will contain terms substantially similar to the terms of the
Preferred Stock (after making appropriate conversion adjustments) and will be
convertible into AIG Common Stock.
 
     Subject to the limitation set forth below, holders of Common Stock that
elect to receive cash will receive $47.00 in cash in exchange for each share of
Common Stock. The maximum aggregate amount of cash that AIG will pay to holders
of Common Stock will be equal to 49.9% of the total value of the consideration
paid to all holders of Common Stock in connection with the Merger (the "Maximum
Cash Pool"). If cash elections are made with respect to more than 49.9% of the
outstanding shares of Common Stock, AIG will make cash payments on a pro rata
basis to holders that elect to receive cash so that the total amount of cash
paid equals the Maximum Cash Pool. The remaining consideration paid to holders
of Common Stock that elect to receive cash will be in the form of AIG Common
Stock.
 
     Subject to AIG's election set forth below, holders of Common Stock that
make no election ("non-electing shareholders") or that elect to receive AIG
Common Stock will receive a portion of a share of AIG Common Stock with a value
equal to $47.00 (as determined based on the average of the closing prices per
share of AIG Common Stock on the NYSE for the ten trading days ending on the
third trading day prior to the date that the Merger is consummated, the "Base
Period Stock Price") in exchange for each share of Common Stock. If the Base
Period Stock Price is less than $104.5625 and cash elections have been made with
respect to less than 49.9% of the outstanding shares of Common Stock, AIG will
be entitled, at its election and subject to the limitations set forth below, to
pay in cash a portion of the consideration to be received by holders of Common
Stock that elect to receive AIG Common Stock or that make no election. The
maximum amount of cash that AIG may elect to pay such holders per share of
Common Stock will be equal to $47.00 minus the product of .4495 and the Base
Period Stock Price (the "Per Share Cash Top-Up Amount"). In addition, the
maximum aggregate amount of cash that AIG may pay to all non-electing
shareholders will be equal to the Maximum Cash Pool minus the aggregate amount
of cash paid to holders of Common Stock that elect to receive cash. The maximum
aggregate amount of cash that AIG may pay to holders of Common Stock that elect
to receive AIG Common Stock will be equal to the lesser of (i) the Maximum Cash
Pool or (ii) the product of the number of shares of Common Stock outstanding
upon consummation of the Merger and the Per Share Cash Top-Up Amount, in each
case minus the aggregate amount of cash paid to holders of Common Stock that
elect to receive cash or that make no election.
 
     Conditions to the Merger.  The completion of the Merger depends upon a
number of conditions being met, including the following:
 
     - the approval of the Merger by the holders of a majority of the
       outstanding shares of Preferred Stock and a majority of the outstanding
       shares of Common Stock, each voting as a separate class;
 
     - that no law has been enacted or injunction entered which effectively
       prohibits the Merger;
 
     - that all necessary approvals of governmental authorities and all material
       required consents of third parties shall have been obtained;
 
     - the receipt of opinions from tax counsel for each company regarding
       certain federal income tax consequences of the Merger;
 
     - that AIG's and American Bankers' respective representations and
       warranties are true and correct in all material respects and the parties
       have performed in all material respects their respective obligations
       under the Merger Agreement; and
 
                                       11

<PAGE>   20
 
     - that the shares of AIG Series C Preferred Stock to be issued to holders
       of Preferred Stock and the shares of AIG Common Stock to be issued to
       holders of Common Stock have been authorized for listing on the NYSE
       subject to official notice of issuance.
 
     Certain of the conditions to the Merger may be waived by the party entitled
to assert the condition.
 
     Termination of the Merger Agreement.  AIG and American Bankers can agree to
terminate the Merger Agreement without completing the Merger, and either of the
companies can terminate the Merger Agreement if any of the following occurs:
 
     - the Merger is not completed by September 30, 1998;
 
     - a court or other governmental authority permanently prohibits the Merger;
       or
 
     - the other company materially breaches or fails to comply with any of its
       representations or warranties or obligations under the Merger Agreement.
 
     In addition, AIG can terminate the Merger Agreement if (A) the required
approval of the holders of Common Stock is not received at the Common
Shareholders Special Meeting, (B) American Bankers enters into a binding
agreement for a business combination with a third party or (C) the American
Bankers Board withdraws or adversely modifies its approval or recommendation of
the Merger Agreement or fails to reconfirm its recommendation of the Merger
Agreement. American Bankers can terminate the Merger Agreement if at any time
after June 19, 1998 the American Bankers Board authorizes American Bankers to
enter into a binding written agreement for a business combination with a third
party and AIG does not make, after at least five business days' notice of such
proposed business combination, an offer that is at least as favorable as such
proposed business combination.
 
     Termination Fee.  The Merger Agreement requires American Bankers to pay to
AIG a termination fee of $66 million if the Merger Agreement is terminated under
certain circumstances.
 
     Regulatory Approvals.  The Hart-Scott-Rodino Antitrust Improvements Act of
1976, as amended, prohibits the companies from completing the Merger until after
the companies have furnished certain information and materials to the Antitrust
Division of the Department of Justice and the Federal Trade Commission and a
required waiting period has ended. On January 20, 1998 the companies furnished
that information and expect that the waiting period will expire on February 19,
1998 unless early termination is granted prior thereto. However, the Department
of Justice and the Federal Trade Commission will continue to have the authority
to challenge the Merger on antitrust grounds before or after the Merger is
completed.
 
     The Merger is also subject to the receipt of certain approvals from various
state and foreign insurance regulatory authorities. In December 1997 and January
1998 AIG made all applicable filings. As of the date of this Proxy
Statement/Prospectus, approvals are pending in certain jurisdictions.
 
     Accounting Treatment.  The Merger will be accounted for under the
"purchase" method of accounting whereby the purchase price paid by AIG will be
allocated based on fair values of assets acquired and liabilities assumed. Such
allocations will be made based upon valuations and other studies that have not
been finalized. The excess of such purchase price over the amounts so allocated
will be treated as goodwill.
 
     Federal Income Tax Consequences.  The Merger generally will not cause
federal income tax to be imposed on holders of Preferred Stock. In addition, the
Merger generally will not cause federal income tax to be imposed on holders of
Common Stock to the extent such holders receive AIG Common Stock. Holders of
Common Stock generally will have to pay federal income taxes on any cash
received by such holders to the extent of any gain they may have on their Common
Stock. In general, such gain will be capital gain. To review the tax
consequences to shareholders in greater detail, see page 32. If the Merger is
restructured as described below in "The Merger Agreement -- Alternative
Transaction Structure" because the holders of Preferred Stock do not approve the
Merger, holders of Common Stock will generally have to pay federal income taxes
on any gain they may have on their Common Stock, even if they receive only AIG
Common Stock in the Merger. There will be no immediate federal income tax
consequences to holders of Preferred Stock in such a circumstance, but a later
conversion of the Preferred Stock into AIG Common Stock would be a taxable
transaction. To review in greater detail the federal income
 
                                       12

<PAGE>   21
 
tax consequences that would result to shareholders if the Merger is so
restructured, see page 52.
 
     TAX MATTERS ARE VERY COMPLICATED AND THE TAX CONSEQUENCES OF THE MERGER TO
SHAREHOLDERS WILL DEPEND ON THEIR INDIVIDUAL CIRCUMSTANCES. SHAREHOLDERS SHOULD
CONSULT THEIR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE TAX CONSEQUENCES TO
THEM OF THE MERGER.
 
     Appraisal Rights.  Under Florida law, holders of Preferred Stock and Common
Stock have no right to an appraisal of the value of their shares in connection
with the Merger.
 
     Listing of AIG Series C Preferred Stock and Common Stock.  AIG will list
the shares of AIG Series C Preferred Stock and AIG Common Stock to be issued in
connection with the Merger on the New York Stock Exchange.
 
RISK FACTORS
 
     In considering whether to approve the Merger Agreement and the consummation
of the Merger, holders of Preferred Stock and Common Stock should carefully
review and consider the information contained below in "Risk Factors."
 
RECENT DEVELOPMENTS
 
     On January 27, 1998, Cendant Corporation ("Cendant") publicly announced a
proposal to acquire American Bankers for $58 per share of Common Stock, to be
paid in cash and common stock of Cendant. In connection with such proposal,
Cendant commenced litigation against American Bankers, members of the American
Bankers Board, AIG and AIGF. On January 28, 1998, Cendant commenced a tender
offer seeking to purchase 23,501,260 shares of Common Stock, subject to the
terms and conditions stated therein, at $58 per share in cash. In addition,
several shareholder suits have been filed asserting essentially the same claims
purportedly on behalf of all American Bankers' shareholders. See "Recent
Developments."
 
STOCK OPTION AGREEMENT
 
     AIG and American Bankers have entered into a Stock Option Agreement under
which American Bankers has granted AIG an option to purchase a number of newly
issued shares of Common Stock equal to approximately 19.9% of the outstanding
shares of Common Stock if certain events occur. The combined value of the
termination fee and the stock option is limited to $66 million. The Stock Option
Agreement may make it more difficult and expensive for American Bankers to
consummate a business combination with a party other than AIG.
 
     Subsequent to the announcement of Cendant's proposal, AIG on January 27,
1998 sent a notice to American Bankers exercising its option to purchase,
subject to applicable regulatory approvals, approximately 19.9% of the
outstanding shares of Common Stock.
 
FORWARD LOOKING STATEMENTS MAY PROVE INACCURATE
 
     THE COMPANIES HAVE MADE FORWARD LOOKING STATEMENTS IN THIS DOCUMENT (AND,
IN THE CASE OF AMERICAN BANKERS, IN DOCUMENTS THAT ARE INCORPORATED BY

FUTURE FINANCIAL AND BUSINESS RESULTS OF AIG AND AMERICAN BANKERS AND COULD
CAUSE THOSE RESULTS TO DIFFER MATERIALLY FROM THOSE EXPRESSED IN THE FORWARD

adjusted to give effect to the Merger and the issuance of an estimated number of
shares of AIG Common Stock and AIG Series C Preferred Stock in connection
therewith, are not expected to differ materially from historical earnings per
share of AIG Common Stock for those periods.

                                  RISK FACTORS
 
     Holders of Preferred Stock and Common Stock should consider carefully all
of the information contained in the Proxy Statement/Prospectus, including the
following factors:
 
ALLOCATION AND PRO-RATION; AIG TOP-UP ELECTION; MARKET FLUCTUATIONS
 
     The Merger Agreement provides that the maximum aggregate amount of cash
that AIG will pay to holders of Common Stock will not exceed the Maximum Cash
Pool. In the event that Cash Elections (as hereinafter defined) are submitted
with respect to an aggregate number of shares of Common Stock which, except for
the limitation imposed by the Maximum Cash Pool, would require AIG to pay cash
in the aggregate in excess of the Maximum Cash Pool, a pro rata portion of such
shares of Common Stock will be converted into the right to receive the Cash
Election Merger Consideration (as hereinafter defined). Such proration as to
each holder of Common Stock will be based upon the ratio of (i) the Maximum Cash
Pool to (ii) the aggregate number of shares of Common Stock with respect to
which Cash Elections are submitted, multiplied by $47.00. All shares of Common
Stock for which a Cash Election is made but for which the Cash Election Merger
Consideration is not paid because of the limitation imposed by the Maximum Cash
Pool, will be converted into the right to receive the Stock Election Merger
Consideration (as hereinafter defined).
 
     The Merger Agreement further provides that holders of Common Stock who make
a Stock Election (as hereinafter defined) or no election generally will receive
AIG Common Stock with a value of $47.00 (as determined based on the Base Period
Stock Price). In the event, however, that the Base Period Stock Price is below
$104.5625 and the entire Maximum Cash Pool has not been paid to holders of
Common Stock that made Cash Elections, AIG will be entitled, at its election, to
pay in cash a portion of the consideration to be received by holders of Common
Stock that make a Stock Election or no election. The maximum amount of cash that
AIG may elect to pay such holders per share of Common Stock will equal the Per
Share Cash Top-Up Amount. In addition, the aggregate amount of cash that AIG may
elect to pay to holders of Common Stock that make a Stock Election or no
election is subject to certain additional limitations, as described under "The
Merger Agreement -- General; the Election; Merger Consideration." Holders of
Common Stock generally will have to pay federal income taxes on any cash
received by such holders to the extent of any gain they may have on their Common
Stock. See "The Merger -- Certain Federal Income Tax Consequences of the
Merger."
 
     Due to the foregoing, no assurance can be given that holders of Common
Stock will receive all of their Merger Consideration (as hereinafter defined) in
the form elected.
 
     In determining whether to make a Stock Election (or no election), holders
of Common Stock are urged to consider the impact of the fluctuations in the
market price of AIG Common Stock. There is no assurance that the market value of
the portion of a share of AIG Common Stock (plus, if applicable, any Per Share
Cash Top-Up Amount) received for each share of Common Stock will equal $47.00 at
the time of closing of the Merger (or thereafter) since the Base Period Stock
Price used to calculate the exchange ratio will be based on the average of the
closing prices of AIG Common Stock on the NYSE for the ten trading days ending
on the third trading day prior to the date of consummating the Merger.
 
ALTERNATIVE TRANSACTION STRUCTURE
 
     In the event that the Merger Agreement is not approved by the holders of a
majority of the outstanding shares of Preferred Stock or AIG reasonably
determines that such approval is not likely to be obtained, the Merger Agreement
provides that the Merger Agreement will be amended to restructure the proposed
Merger. The amended Merger Agreement, inter alia, would (i) provide that AIGF
would be merged into American Bankers (in lieu of the proposed merger of
American Bankers into AIGF), (ii) provide that the shares of Preferred Stock
would remain outstanding after the Merger pursuant to their existing terms and
conditions (except that appropriate conversion adjustments would be made and
such shares would become convertible into AIG Common Stock) and (iii) eliminate
certain tax-related covenants and conditions contained in the Merger Agreement.
Such amended Merger Agreement would require the approval of the holders of a
majority of the outstanding shares of Common Stock, but would not require the
approval of the holders of shares of Preferred Stock.
 
     In the event that the amended Merger Agreement is approved by the holders
of Common Stock, such holders generally will have to pay federal income tax on
all Merger Consideration, whether in the form of cash or AIG Common Stock, that
they receive in the Merger to the extent of any gain they may have on their
Common Stock. See "The Merger Agreement -- Alternative Transaction Structure."

business on January 30, 1998 (the "Record Date") are entitled to notice of and
to vote at the Preferred Shareholders Special Meeting. Holders of shares of
Preferred Stock have no dissenters' rights of appraisal in connection with the
Merger.
 
     All voting rights for the Common Shareholders Special Meeting are vested
exclusively in the holders of Common Stock, with each share entitled to one
vote. Only holders of shares of Common Stock of record at the close of business
on the Record Date are entitled to notice of and to vote at the Common
Shareholders Special Meeting. Holders of shares of Common Stock have no
dissenters' rights of appraisal in connection with the Merger.
 
     Approval and adoption of the Merger Agreement and the Merger requires the
affirmative vote by the holders of (i) at least a majority of the shares of
Preferred Stock outstanding as of the Record Date and (ii) at least a majority
of the shares of Common Stock outstanding as of the Record Date, each voting as
a separate class.
 
     Under NYSE rules, brokers and nominees are precluded from exercising their
voting discretion on the proposal to approve and adopt the Merger Agreement and
the Merger and, for this reason, absent specific instructions from the
beneficial owner of shares, are not permitted to vote such shares thereon.
Because the affirmative vote of a majority of the shares of Preferred Stock and
Common Stock, outstanding on the Record Date, each voting as a class, is
required for approval of the Merger, a broker non-vote or an abstention with
respect to the Merger will have the effect of a vote against the Merger.
 
     As of the Record Date, directors and executive officers of American Bankers
and their affiliates as a group did not beneficially own any shares of Preferred
Stock. As of the Record Date, directors and executive officers of American
Bankers and their affiliates as a group beneficially owned 4,177,200 shares of
Common Stock, or approximately 9.9% of the shares of Common Stock outstanding as
of the Record Date. Messrs. R. Kirk Landon, Chairman of the American Bankers
Board, and Gerald N. Gaston, Vice Chairman, President and Chief Executive
Officer, of American Bankers, who held in the aggregate as of the Record Date
approximately 8.0% of the combined voting power of the Common Stock outstanding
as of the Record Date, have entered into a voting agreement (the "Voting
Agreement"), in which they have agreed, among other things, to vote all of their
shares of Common Stock in favor of the adoption and approval of Merger Agreement
and the Merger. See "Related Agreements and Transactions -- Voting Agreement".
Based on the approximately 42,205,238 shares of Common Stock outstanding as of
the Record Date, a total of approximately 21,102,620 shares of Common Stock are
required to be voted in favor of the Merger Agreement and
 
                                       20

<PAGE>   29
 
the Merger in order for the Merger Agreement and the Merger to be approved by
the holders of the Common Stock. Accordingly, American Bankers directors,
executive officers and their affiliates hold shares representing approximately
19.8% of the total number of shares of Common Stock required for approval of the
Merger Agreement and the Merger. Holders of approximately 16.0% of the total
number of shares of Common Stock required for approval of the Merger Agreement
and the Merger have contractually agreed to vote in favor of the Merger
Agreement and the Merger.
 
QUORUM
 
     The Florida Business Corporation Act (the "FBCA"), the American Bankers
Third Amended and Restated Articles of Incorporation (the "American Bankers
Articles"), the American Bankers Bylaws (the "American Bankers Bylaws") and the
Exchange Act contain requirements governing the actions of American Bankers
shareholders at the Special Meetings. According to the American Bankers Bylaws,
holders of a majority of the shares of Preferred Stock outstanding on the Record
Date must be present, either in person or by proxy, at the Preferred
Shareholders Special Meeting to constitute a quorum, and holders of a majority
of the shares of Common Stock outstanding on the Record Date must be present,
either in person or by proxy, at the Common Shareholders Special Meeting to
constitute a quorum. In general, abstentions and broker non-votes are counted as
present or represented for the purposes of determining a quorum for the Special
Meetings.
 
EXPENSES OF SOLICITATION
 
     The expenses of this solicitation will be borne by American Bankers. In
addition to solicitation by mail, arrangements will be made with brokers and
other custodians, nominees and fiduciaries to send proxy materials to their
principals and American Bankers will, upon request, reimburse them for
reasonable expenses of so doing. Solicitation of proxies from some shareholders
may be made by American Bankers' officers and regular employees by telephone,
facsimile, or in person after the initial solicitation. In addition, MacKenzie
Partners, Inc. ("MacKenzie") has been retained to assist in the solicitation of
proxies. MacKenzie may contact holders of shares of Preferred Stock and Common
Stock by mail, telephone, facsimile, telegraph and personal interviews and may
request brokers, dealers and other nominee shareholders to forward materials to
beneficial owners of shares of Preferred Stock and Common Stock. MacKenzie will
receive reasonable and customary compensation for its services (estimated at
$15,000), will be reimbursed for certain reasonable out-of-pocket expenses and
will be indemnified against certain liabilities and expenses in connection
therewith, including certain liabilities under the federal securities laws.
 
MISCELLANEOUS
 
     It is not expected that any matter not referred to herein will be presented
for action at the Special Meetings. If any other matters are properly brought
before the Special Meetings, the persons named in the proxies will have
discretion to vote on such matters in accordance with their best judgment. The
grant of a proxy will also confer discretionary authority on the persons named
in the proxy as proxy appointees to vote in accordance with their best judgment
on matters incident to the conduct of the Special Meetings, including (except as
stated in the following sentence) postponement or adjournment for the purpose of
soliciting additional votes. However, shares represented by proxies that have
been voted "AGAINST" the Merger Agreement and the Merger will not be used to
vote "FOR" postponement or adjournment of the Special Meetings for the purposes
of allowing additional time for soliciting additional votes "FOR" the approval
and adoption of the Merger Agreement and the Merger.
 
     As soon as practicable following the Preferred Shareholders Special
Meeting, American Bankers will publicly announce by means of a press release the
results of the vote at that meeting and, if the Merger is not approved by the
requisite vote of the holders of Preferred Stock, will file with the Commission
and mail to the holders of Common Stock a supplement to this Proxy
Statement/Prospectus which contains the results. In that event, the Common
Shareholders Special Meeting will be postponed to a later date, to enable the
holders of Common Stock to evaluate the information contained in the supplement.
 
     Holders of Preferred Stock should not send their stock certificates with
their proxy cards. Holders of Common Stock should send in their proxy cards and
separately should send in the enclosed Election Form properly completed with
their stock certificates. An election to receive cash or stock in the Merger
will not constitute a vote in favor of approval of the Merger.

                                   THE MERGER
 
BACKGROUND OF THE MERGER
 
     In the spring of 1997, Barclays Capital ("Barclays"), in the course of
discussions with a representative of American Bankers concerning banking
matters, raised with American Bankers the possibility of forming a relationship
with AIG. A meeting was arranged among Gerald N. Gaston, Vice Chairman,
President and Chief Executive Officer, and Floyd G. Denison, Executive Vice
President, of American Bankers, representatives of Barclays, and Howard I.
Smith, Executive Vice President and Chief Financial Officer of AIG, and other
members of AIG's management. At that meeting on March 4, 1997, no specific
transaction was discussed and management of American Bankers informed AIG that
the company was not for sale. Following the meeting, however, AIG and American
Bankers entered into a confidentiality agreement, dated April 30, 1997, for the
purpose of exploring a possible relationship between the two companies.
 
     On May 9, 1997, management of American Bankers and representatives of Smith
Barney Inc. (now associated with Salomon Brothers Inc and, collectively with
Salomon Brothers Inc, doing business as and referred to herein as "Salomon Smith
Barney"), met with Mr. Smith and other representatives of AIG, representatives
of Barclays and representatives of Goldman, Sachs & Co. ("Goldman Sachs"), which
had been retained by AIG, to discuss the nature of AIG's interest in American
Bankers and to refine and develop a due diligence list initially prepared by
AIG.
 
     On May 23, 1997, at its regularly scheduled meeting, the American Bankers
Board was informed of the discussions that had taken place with AIG. The
American Bankers Board authorized the Chief Executive Officer, Chairman of the
Board and other appropriate officers of American Bankers to respond to requests
for information regarding American Bankers' business and to review and discuss
with AIG possible forms of joint business arrangements. At that time, the
American Bankers Board informed management that American Bankers was not for
sale. Also at this meeting the American Bankers Board authorized the retention
of Salomon Smith Barney to advise American Bankers regarding a potential
transaction with AIG. American Bankers executed an engagement letter with
Salomon Smith Barney on August 13, 1997.
 
     Maurice R. Greenberg, Chairman and Chief Executive Officer of AIG, and Mr.
Smith met with Mr. Gaston and Mr. Denison during May and June of 1997. Mr.
Greenberg expressed skepticism concerning a possible joint venture or business
combination with American Bankers because AIG estimated that it would realize an
insufficient rate of return on its investment based on 1997 and 1998 earnings
estimates for American Bankers derived from publicly available information
concerning American Bankers. Soon thereafter, however, Mr. Greenberg requested
that Mr. Smith meet with Mr. Denison to study possible synergies and expense
savings that might result from a business combination between AIG and American
Bankers.
 
     On July 9, 1997, the American Bankers Board met and was informed of AIG's
views regarding a possible transaction.
 
     On July 10, 1997, Messrs. Denison and Gaston met with Messrs. Smith and
Louis F. Zearo, Vice President and Deputy Comptroller of AIG. At that meeting,
Mr. Smith reiterated Mr. Greenberg's statement that AIG considered a transaction
between AIG and American Bankers to be unlikely. Notwithstanding Mr. Smith's
statement, possible synergies and expense savings were discussed and Mr. Smith
requested more detailed expense information on American Bankers' operations.
 
     On July 29, 1997, management of American Bankers presented Mr. Smith with a
written analysis regarding possible synergies and expense savings.
 
     In August 1997, AIG requested that management of American Bankers allow
representatives of AIG to visit American Bankers to review American Bankers'
business and to consider possible synergies and expense savings and revenue
enhancement issues. During that month, two groups from AIG visited American
Bankers. The first group, which included Mr. Zearo and certain data processing
and marketing personnel of AIG, met with, among other officers of American
Bankers, R. Kirk Landon, Chairman of the American Bankers Board, and Messrs.
Gaston and Denison. Their visit included a review of American Bankers' data
processing facilities. The second group, comprised of all marketing personnel,
met with Messrs. Gaston, Gene Becker, Chief
 
                                       22

<PAGE>   31
 
Marketing Officer of American Bankers, and Jay Fuchs, President of American
Bankers Insurance Company of Florida and American Bankers Life Assurance Company
of Florida, and other marketing personnel from American Bankers, to review
American Bankers' marketing structure.
 
     Throughout August 1997, American Bankers continued to work on refining its
analysis of possible synergies and expense savings. During the months of
September and October, discussions took place as to possible additional visits
by officers of AIG, including Mr. Greenberg, for the purpose of evaluating the
possibility of a business combination.
 
     Subsequently, Mr. Greenberg, in a series of calls to Mr. Gaston, expressed
serious interest in going forward with a business combination and stated that he
would get back to Mr. Gaston sometime immediately after Thanksgiving.
Accordingly, a meeting was arranged for December 5, 1997.
 
     On December 5, 1997, Messrs. Gaston and Denison met with Messrs. Greenberg,
Smith and Edward E. Matthews, Vice Chairman -- Investments and Financial
Services, of AIG, to discuss AIG's interest in a possible business combination.
During the meeting, the basic form of a proposed transaction was discussed.
Following the meeting, Mr. Gaston asked Mr. Greenberg to prepare written
materials for presentation to the American Bankers Board. Mr. Gaston again
emphasized that American Bankers was not for sale but said that he would advise
the American Bankers Board of AIG's proposal and subsequently respond to AIG.
 
     On December 6, 1997, Mr. Matthews delivered to Mr. Gaston a list containing
certain terms of AIG's proposal to acquire American Bankers by exchanging $45.51
in AIG Common Stock for each share of Common Stock.
 
     On December 13, 1997, James F. Jorden, a director of American Bankers,
presented the proposed transaction to the American Bankers Board and reviewed in
detail the history of the discussions with AIG. In addition, at that meeting
Salomon Smith Barney discussed its preliminary analysis of the proposed
transaction, including its detailed financial and other analyses of American
Bankers and AIG, and management of American Bankers discussed its views of the
growth prospects for American Bankers. After these presentations, the American
Bankers Board directed management of American Bankers to enter into negotiations
with AIG with a view to combining the two corporations.
 
     On December 15, 1997, Messrs. Greenberg, Matthews and Smith met with
Messrs. Gaston and Denison to discuss the terms of AIG's proposal. On December
16, 1997, AIG indicated that it was prepared to increase its offer to $46.00 in
AIG Common Stock for each share of Common Stock. Mr. Gaston indicated that he
would inform the American Bankers Board regarding AIG's proposal.
 
     Over the next several days, negotiations concerning the terms of a possible
transaction continued. Those negotiations included, in addition to continuing
discussions on the price per share to be received by holders of Common Stock,
discussions regarding AIG paying a portion of the consideration to be paid to
holders of Common Stock in cash, the treatment of the Preferred Stock in the
transaction and the nature and amount of any termination fees. AIG also proposed
that American Bankers grant AIG an option to purchase up to 19.9% of the
outstanding Common Stock, and that certain officers of American Bankers enter
into agreements to vote in favor of the transaction. AIG indicated that it would
not enter into any transaction that did not include a termination fee and
agreements similar to those contained in the Voting Agreement and the Stock
Option Agreement, dated as of December 21, 1997, between AIG and American
Bankers (the "Stock Option Agreement"). American Bankers indicated to AIG that
it would consider granting such an option, but only if the amount which could be
realized by AIG with respect to it, in conjunction with any amount realized with
respect to the termination fee, was capped. In addition, during this period AIG
and American Bankers each continued their due diligence reviews of the other.
 
     On December 18, 1997, Sullivan & Cromwell, counsel to AIG delivered to
Dewey Ballantine LLP, counsel to American Bankers and Jorden Burt Berenson &
Johnson LLP, counsel to American Bankers, drafts of the Merger Agreement, Stock
Option Agreement and Voting Agreement. On December 19 through 21, AIG, American
Bankers, Goldman Sachs, Salomon Smith Barney, Sullivan & Cromwell, Dewey
Ballantine LLP and Jorden Burt Berenson & Johnson LLP negotiated the terms of
those agreements. AIG and American Bankers discussed an increase in the proposed
Merger Consideration to $47.50 per share of
 
                                       23

<PAGE>   32
 
Common Stock but ultimately agreed upon $47.00 in connection with finalizing all
of the terms of the Merger Agreement.
 
     On December 19, 1997 the AIG Board approved the proposed transaction.
 
     Also on December 19, 1997, American Bankers amended the Rights Agreement
(as hereinafter defined) to provide that the execution, delivery or consummation
of the transactions contemplated by the Merger Agreement, the Stock Option
Agreement and the Voting Agreement will not cause the rights contemplated by the
Rights Agreement to become exercisable.
 
     At a meeting held on December 21, 1997, the American Bankers Board received
from Mr. Jorden an update on the discussions with AIG that had occurred since
its last meeting. The American Bankers Board also received a detailed due
diligence review concerning AIG from Mr. Denison. Dewey Ballantine LLP reviewed
for the American Bankers Board its fiduciary duties, and described the principal
terms of the Merger Agreement, Stock Option Agreement and Voting Agreement.
Salomon Smith Barney presented its fairness opinion, and described for the
American Bankers Board the detailed analysis conducted by Salomon Smith Barney
in reaching its conclusions. The American Bankers Board asked numerous questions
of management of American Bankers, Salomon Smith Barney and Dewey Ballantine
LLP. Thereafter, following further discussion, the American Bankers Board
unanimously determined that the Merger is fair to, and in the best interests of,
American Bankers and its shareholders (including holders of Preferred Stock and
Common Stock). Accordingly, the American Bankers Board unanimously approved the
Merger Agreement, Stock Option Agreement and Voting Agreement and the Merger,
and resolved unanimously to recommend that the shareholders of American Bankers
(including holders of Preferred Stock and Common Stock) vote for approval and
adoption of the proposed Merger Agreement and the Merger.
 
     Later on December 21, 1997, the Merger Agreement and Stock Option Agreement
were executed by American Bankers and AIG, and the Voting Agreement was executed
by Messrs. Gaston and Landon and AIG.
 
PROJECTIONS
 
     As part of its due diligence review of American Bankers, AIG received from
American Bankers certain non-public information. The non-public information
included, among other things, American Bankers' projections of the financial
condition and results of operations for American Bankers for the years 1997
through 2001 (the "Projections"). The Projections were provided to AIG on May
22, 1997 and did not include the impact of any possible synergies or expense
savings which might be realized in connection with the Merger.
 
     The following table sets forth certain information contained in the
Projections.

</TABLE>

 
     American Bankers has advised AIG that it does not as a matter of course
disclose its internal projections. The Projections were not prepared with a view
to public disclosure or compliance with published guidelines of the Commission
or the American Institute of Certified Public Accountants for prospective
financial information. Certain information from the Projections is included
herein solely because the Projections were furnished to AIG. Accordingly, the
inclusion of such information in this Proxy Statement/Prospectus should not be
regarded as an indication that American Bankers, AIG or their respective
financial advisors or their respective officers and directors consider such
information to be accurate or reliable and none of such persons assumes any
responsibility for the accuracy thereof. The projections included in this Proxy
State-
 
                                       24

<PAGE>   33
 
ment/Prospectus have been prepared by, and are the responsibility of, American
Bankers' management. Price Waterhouse LLP has neither examined nor compiled
these projections, and accordingly, Price Waterhouse LLP does not express an
opinion or any other form of assurance with respect thereto. The Price
Waterhouse LLP report incorporated by reference in this Proxy
Statement/Prospectus relates to the American Bankers historical financial data.
It does not extend to the projections and should not be read to do so. The
Projections were prepared for internal use and capital budgeting and other
management decision-making purposes and are subjective in many respects and thus
susceptible to various interpretations and periodic revision based upon actual
experience and business development. In addition, because the assumptions
underlying the Projections are inherently subject to significant economic and
competitive uncertainties and contingencies, which are difficult or impossible
to predict accurately and are beyond the control of American Bankers and AIG,
there can be no assurance that the results contemplated by the Projections set
forth above will be realized. Accordingly, there may be differences between
actual results and the results contemplated by the Projections, and actual
results may be materially higher or lower than those set forth above. American
Bankers has informed AIG that, despite the publication of the portion of the
Projections covering results for the year ended December 31, 1997, it does not
intend to disclose publicly whether its actual results for that year will vary
from the Projections other than through the release of actual results in the
ordinary course of business.
 
     In connection with its consideration of the Merger, management of American
Bankers subsequently prepared revised projections of American Bankers' financial
condition and results of operations for the five-year period that differ from
the Projections primarily in that they reflect lower estimated revenue and net
income for the years in the period following 1999 as a result of management's
using different assumptions regarding the prospects for revenue growth for those
years. These revised projections were prepared in response to hypothetical
questions from members of the American Bankers Board concerning the prospects of
American Bankers assuming slower growth than American Bankers had historically
achieved. These revised projections were not provided to AIG, but were provided
to Salomon Smith Barney in connection with the preparation of its fairness
opinion.
 
REASONS FOR THE MERGER; RECOMMENDATION OF THE AMERICAN BANKERS BOARD
 
     In reaching its determination to recommend approval and adoption of the
Merger Agreement and the Merger, the American Bankers Board consulted with
American Bankers management, as well as Dewey Ballantine LLP and Salomon Smith
Barney, and considered a number of factors, including the following. In view of
the wide variety of factors considered in connection with the Merger, the
American Bankers Board did not consider it practicable to, nor did it attempt
to, quantify or otherwise assign relative weights to the specific factors it
considered in reaching its decision.
 
          (i) American Bankers' Business, Condition and Prospects.  The American
     Bankers Board considered information with respect to the financial
     condition, results of operations and business of American Bankers, on both
     an historical and prospective basis, and current industry, economic and
     market conditions, including American Bankers' market position in the
     domestic credit insurance market and the recent emphasis on developing
     international credit insurance markets for American Bankers. The members of
     the American Bankers Board were familiar with and knowledgeable about
     American Bankers' business and affairs and further reviewed these matters
     in the course of their deliberations. The American Bankers Board considered
     American Bankers' historical growth and the capital requirements which
     would be needed to sustain a similar level of growth in the future, given
     the dominant position held by American Bankers in the domestic credit
     insurance market. The American Bankers Board noted that there could be no
     assurance as to American Bankers' access to such capital on acceptable
     terms.
 
          (ii) Potential Synergies.  The American Bankers Board considered that
     a combination with AIG would allow access to AIG's considerable
     international experience and substantial resources, at a time of industry
     consolidation, which would enable American Bankers to expand beyond the
     domestic market. The American Bankers Board also considered that a
     combination with AIG would allow American Bankers to enjoy opportunities
     for operating efficiencies and synergies as a result of the Merger,
     particularly in the international distribution of American Bankers'
     products.
 
                                       25

<PAGE>   34
 
          (iii) AIG's Business, Condition and Prospects.  The American Bankers
     Board considered information with respect to the financial condition,
     results of operations and business of AIG. Management and Salomon Smith
     Barney made presentations to and provided the American Bankers Board with
     information regarding AIG's financial condition and prospects after
     conducting due diligence with representatives of AIG. Salomon Smith Barney
     also advised the American Bankers Board concerning research analysts' views
     of AIG. In evaluating AIG's prospects, the American Bankers Board
     considered, among other things, its international experience and its depth
     of knowledge and experience in regulatory matters. The American Bankers
     Board also considered that AIG's long-term debt rating and the claims
     paying ratings of AIG's insurance subsidiaries were substantially higher
     than the comparable ratings of American Bankers. The American Bankers Board
     believed that such higher long-term debt rating would enable American
     Bankers to have access to capital on more favorable terms and such higher
     claims-paying ratings would enhance sales of American Bankers' insurance
     products.
 
          (iv) Terms of the Merger.  The American Bankers Board considered the
     terms and provisions of the Merger Agreement, the Stock Option Agreement
     and the Voting Agreement. The American Bankers Board considered the fact
     that the terms of the Merger permit holders of Common Stock to continue to
     hold a common equity interest in AIG following the Merger, thus enabling
     holders of Common Stock to participate in the synergies expected to result
     from the combination of the two companies. The American Bankers Board
     considered the terms of the Merger Agreement that permit the American
     Bankers Board, subject to the limitations described below in "The Merger
     Agreement -- Agreement Not to Solicit Other Offers", to receive unsolicited
     inquiries and proposals from, and negotiate and give information to, third
     parties. The American Bankers Board further considered that the total
     amount which could be realized by AIG pursuant to the termination fee and
     the Stock Option Agreement was capped at $66 million. The American Bankers
     Board found reasonable the views of Dewey Ballantine LLP and Salomon Smith
     Barney that a $66 million termination fee was within the range of fees
     payable in comparable transactions and that the fee, in conjunction with
     the Stock Option Agreement and the Voting Agreement, would not in and of
     itself preclude alternative proposals, although the American Bankers Board
     did note that the exercise by AIG of the option contemplated by the Stock
     Option Agreement would prevent any third party from engaging in a
     transaction with American Bankers which could be accounted for as a
     "pooling of interests," making any such alternative proposal less likely.
     The American Bankers Board further considered that AIG had stated that it
     would not enter into a transaction which did not include provisions similar
     to the termination fee, Stock Option Agreement and Voting Agreement. The
     American Bankers Board also considered the fact that under the terms of the
     Merger Agreement, the holders of Preferred Stock will receive AIG Series C
     Preferred Stock with substantially similar terms as the Preferred Stock
     (after making appropriate conversion adjustments), except that the AIG
     Series C Preferred Stock will be convertible into shares of AIG Common
     Stock. The American Bankers Board further considered that the Merger
     (unless it is restructured as described below in "The Merger
     Agreement -- Alternative Transaction Structure" following a failure of the
     holders of Preferred Stock to approve the Merger Agreement and the Merger)
     generally is not expected to result in federal income taxes to the extent
     that holders of Common Stock receive AIG Common Stock (although the Board
     did note that any cash received by holders of Common Stock would be taxable
     to such holders, as described below in "The Merger -- Certain Tax
     Consequences" to the extent of any gain that such holders may have on their
     Common Stock). The American Bankers Board noted the "cash election" feature
     of the Merger, which allows, subject to certain limitations, holders of
     Common Stock to elect to receive either cash or shares of AIG Common Stock.
     Finally, the American Bankers Board considered AIG's agreement to appoint
     all of the existing directors of American Bankers to the Board of Directors
     of the Surviving Corporation immediately following consummation of the
     Merger.
 
          (v) Opinion of Salomon Smith Barney.  The American Bankers Board
     considered the oral opinion delivered on December 21, 1997 by Salomon Smith
     Barney (which it subsequently confirmed by delivery of a written opinion
     dated December 21, 1997) that as of the date of such opinion, and based
     upon and subject to certain matters stated therein, the Common Stock Merger
     Consideration (as defined in such opinion) is fair, from a financial point
     of view, to the holders of Common Stock and the Preferred Stock Merger
     Consideration (as defined in such opinion) is fair, from a financial point
     of view, to the holders of
 
                                       26

     Preferred Stock. The American Bankers Board also considered the oral and
     written presentations made to it by Salomon Smith Barney. See "The
     Merger -- Opinion of American Bankers' Financial Advisor." A copy of
     Salomon Smith Barney's written opinion to the American Bankers Board, dated
     December 21, 1997, which sets forth the assumptions made, matters
     considered and limitations on the review undertaken, is attached as
     Appendix IV to this Proxy Statement/Prospectus and is incorporated herein
     by reference.
 
          (vi) Historical and Recent Market Prices Compared to Consideration to
     be Received by Holders of Common Stock.  The American Bankers Board
     reviewed the historical market prices and recent trading activity of the
     Common Stock, and noted that the Common Stock was trading in general in the
     period preceding the announcement of the Merger at historically high
     levels. The American Bankers Board considered the fact that the value to be
     received per share of Common Stock represented a significant premium over
     the trading levels of the Common Stock during the six-month period
     preceding the public announcement of the Merger. The American Bankers Board
     also considered the fact that the Merger Agreement fixes a value of $47.00
     for each share of Common Stock outstanding, so that holders of Common Stock
     are not at risk if the market price of AIG Common Stock were to decline
     between the date of the Merger Agreement and the Effective Time.
 
          (vii) Countervailing Considerations.  The American Bankers Board
     considered certain factors that might be characterized as countervailing
     factors, including:
 
             (a) The fact that AIG's price/earnings ratio is currently at an
        historically high level. The American Bankers Board noted that it might
        be problematic for AIG to maintain this high level, and that if the high
        level is not maintained by AIG, it is possible that the market price of
        the AIG Common Stock could drop in the future from its current levels.
 
             (b) The recent turmoil in the financial markets in Asia, which may
        have a negative effect on the business of AIG and could have a negative
        effect on the price of AIG Common Stock. In this regard the American
        Bankers Board noted the large amount of business conducted in Asia by
        AIG.
 
             (c) The fact that under the terms of the Merger Agreement, under
        certain circumstances described below in "The Merger Agreement," a
        portion of the consideration paid to holders of Common Stock may be paid
        in cash at the election of AIG, and that such cash consideration would
        be taxable to the holders of Common Stock.
 
             (d) The fact that, if the Merger Agreement and the Merger are not
        approved by the holders of Preferred Stock, the Merger Agreement
        provides that the transaction will be restructured, as described below
        in "The Merger Agreement -- Alternative Transaction Structure," without
        any further action, including any action by the American Bankers Board.
        In that regard, the American Bankers Board noted that the transaction as
        restructured would not require the approval of the holders of the
        Preferred Stock, but would still require the approval of the holders of
        Common Stock. The American Bankers Board further noted that the
        transaction as restructured would be taxable to holders of Common Stock
        to the extent of any gain they may have on their Common Stock, as
        described more fully below in "The Merger Agreement -- Alternative
        Transaction Structure."
 
          (viii) Conflicts of Interest.  The American Bankers Board reviewed the
     matters discussed below in "The Merger -- Interests of Certain Persons in
     the Merger" and determined that such matters did not affect the American
     Bankers Board's assessment of the Merger and the value which it presented
     to holders of Preferred Stock and Common Stock.
 
     THE AMERICAN BANKERS BOARD HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT,
HAS DETERMINED THAT THE MERGER IS FAIR TO, AND IN THE BEST INTERESTS OF,
AMERICAN BANKERS AND ITS SHAREHOLDERS (INCLUDING HOLDERS OF BOTH PREFERRED STOCK
AND COMMON STOCK), AND RECOMMENDS THAT HOLDERS OF PREFERRED STOCK AND COMMON
STOCK VOTE FOR APPROVAL AND ADOPTION OF THE MERGER AGREEMENT AND THE MERGER.

OPINION OF AMERICAN BANKERS' FINANCIAL ADVISOR
 
     Salomon Smith Barney was retained by American Bankers to act as its
financial advisor in connection with the proposed Merger. In connection with
such engagement, American Bankers requested that Salomon Smith Barney evaluate
the fairness, from a financial point of view, to holders of Common Stock and to
holders of Preferred Stock of the consideration to be received by such holders
pursuant to the terms of the Merger Agreement. On December 21, 1997, at a
meeting of the American Bankers Board held to evaluate the Merger, Salomon Smith
Barney delivered an oral opinion (subsequently confirmed by delivery of a
written opinion dated December 21, 1997) to the American Bankers Board to the
effect that, as of the date of such opinion and based upon and subject to
certain matters stated therein, the Common Stock Merger Consideration was fair,
from a financial point of view, to the holders of Common Stock, and the
Preferred Stock Merger Consideration was fair, from a financial point of view,
to the holders of Preferred Stock.
 
     In arriving at its opinion, Salomon Smith Barney reviewed a draft of the
Merger Agreement and held discussions with certain senior officers, directors
and other representatives and advisors of American Bankers and certain senior
officers and other representatives and advisors of AIG concerning the
businesses, operations and prospects of American Bankers and AIG. Salomon Smith
Barney examined certain publicly available business and financial information
relating to American Bankers and AIG as well as certain financial forecasts for
American Bankers and other information and data for American Bankers and AIG
which were provided to or otherwise discussed with Salomon Smith Barney by the
respective managements of American Bankers and AIG, including information
relating to certain strategic implications and operational benefits anticipated
to result from the Merger. Salomon Smith Barney reviewed the financial terms of
the Merger as set forth in the Merger Agreement in relation to, among other
things: (i) current and historical market prices and trading volumes of the
Common Stock and AIG Common Stock; (ii) the historical and projected earnings
and other operating data of American Bankers and AIG; and (iii) the
capitalization and financial condition of American Bankers and AIG. Salomon
Smith Barney also considered, to the extent publicly available, the financial
terms of certain other similar transactions recently effected which Salomon
Smith Barney considered relevant in evaluating the Merger and analyzed certain
financial, stock market and other publicly available information relating to the
businesses of other companies whose operations Salomon Smith Barney considered
relevant in evaluating those of American Bankers and AIG. Salomon Smith Barney
also evaluated the potential pro forma financial impact of the Merger on AIG. In
addition to the foregoing, Salomon Smith Barney conducted such other analyses
and examinations and considered such other financial, economic and market
criteria as Salomon Smith Barney deemed appropriate in arriving at its opinion.
Salomon Smith Barney noted that its opinion was necessarily based upon
information available, and financial, stock market and other conditions and
circumstances existing and disclosed to Salomon Smith Barney, as of the date of
its opinion.
 
     In rendering its opinion, Salomon Smith Barney assumed and relied, without
independent verification, upon the accuracy and completeness of all financial
and other information and data publicly available or furnished to or otherwise
reviewed by or discussed with Salomon Smith Barney. Salomon Smith Barney also
assumed, with the consent of the American Bankers Board, that the final terms of
the Merger Agreement reviewed by Salomon Smith Barney in draft form would not
vary materially from the draft reviewed by Salomon Smith Barney. With respect to
financial forecasts and other information and data furnished to or otherwise
reviewed by or discussed with Salomon Smith Barney, the management of American
Bankers advised Salomon Smith Barney that such forecasts and other information
and data were reasonably prepared on bases reflecting the best currently
available estimates and judgments of the management of American Bankers as to
the future financial performance of American Bankers and the strategic
implications and operational benefits anticipated to result from the Merger.
Salomon Smith Barney's opinion, as set forth therein, relates to the relative
values of American Bankers and AIG. Salomon Smith Barney did not express any
opinion as to what the value of the AIG Common Stock or AIG Series C Preferred
Stock actually will be when issued pursuant to the Merger or the price at which
the AIG Common Stock or AIG Series C Preferred Stock will trade subsequent to
the consummation of the Merger. Salomon Smith Barney did not make and was not
provided with an independent evaluation or appraisal of the assets or
liabilities (contingent or otherwise) of American Bankers or AIG nor did Salomon
Smith Barney make any physical inspection of the properties or assets of
American Bankers or AIG. Salomon Smith Barney was not requested to and did not
 
                                       28

<PAGE>   37
 
approach third parties or hold discussions with third parties to solicit
indications of interest in the possible acquisition of American Bankers. No
other limitations were imposed by American Bankers on Salomon Smith Barney with
respect to the investigations made or procedures followed by Salomon Smith
Barney in rendering its opinion.
 
     In preparing its opinion to the American Bankers Board, Salomon Smith
Barney performed a variety of financial and comparative analyses, including
those described below performed by Salomon Smith Barney in connection with its
opinion dated December 21, 1997. The summary of such analyses does not purport
to be a complete description of the analyses underlying Salomon Smith Barney's
opinion. The preparation of a financial opinion is a complex analytic process
involving various determinations as to the most appropriate and relevant methods
of financial analyses and the application of those methods to the particular
circumstances and, therefore, such an opinion is not readily susceptible to
summary description. Salomon Smith Barney believes that its analyses must be
considered as a whole and that selecting portions of such analyses or any of the
individual factors considered, without considering all analyses and factors,
could create a misleading or incomplete view of the processes underlying such
analyses and its opinion. In its analyses, Salomon Smith Barney made numerous
assumptions with respect to American Bankers, AIG, industry performance, general
business, economic, market and financial conditions and other matters, many of
which are beyond the control of American Bankers and AIG. The estimates
contained in such analyses and the valuation ranges resulting from any
particular analysis are not necessarily indicative of actual values or
predictive of future results or values, which may be significantly more or less
favorable than those suggested by such analyses. In addition, analyses relating
to the value of businesses or securities do not purport to be appraisals or to
reflect the prices at which businesses or securities actually may be sold.
Accordingly, such analyses and estimates are inherently subject to substantial
uncertainty. Salomon Smith Barney's opinion and financial analyses were only one
of many factors considered by the American Bankers Board in its evaluation of
the Merger and should not be viewed as determinative of the views of the
American Bankers Board or management with respect to the Merger.
 
     The following is a summary of the material financial analyses performed by
Salomon Smith Barney in connection with its opinion dated December 21, 1997:
 
     Selected Insurance Transactions Analysis.  Using publicly available
information, Salomon Smith Barney analyzed the purchase price and implied
transaction multiples paid in eight selected transactions in the insurance
industry consisting of (target/acquiror): CapMAC Holdings, Inc./MBIA Inc., Omni
Insurance Group/The Hartford Financial Services Group, Inc., Titan Holdings
Inc./USF&G Corporation, Colonial Penn Group Inc./GE Capital Corp., American
States Financial Corp./Safeco Corp., Johnson & Higgins/Marsh & McLennan
Companies, Inc., AVEMCO Corporation/HCC Insurance Holdings, Inc. and Alexander &
Alexander Services Inc./Aon Corporation (collectively, the "Selected
Transactions"). Salomon Smith Barney compared the purchase prices in such
transactions as multiples of, among other things, net income for the last 12
months computed in accordance with generally accepted accounting principles
("GAAP"), estimated GAAP net income for the next year and book value as of the
most recent date. All multiples for the Selected Transactions were based on
information available at the time of announcement of the transactions. Applying
a range of selected multiples for the Selected Transactions of GAAP net income
for the last 12 months, estimated GAAP net income for the next year and most
recent book value of 16.0x to 21.0x, 15.0x to 19.0x and 2.20x to 2.90x,
respectively, to corresponding financial data for American Bankers resulted in
an average equity reference range for American Bankers of approximately $40.35
to $48.82 per share on a fully diluted basis, as compared to the $47.00 per
share value provided in the Merger.
 
     Selected Public Company Analysis.  Using publicly available information,
Salomon Smith Barney analyzed, among other things, the market values and trading
multiples of American Bankers, AIG and eight selected publicly traded property
and casualty insurance companies, consisting of: Allstate Corp., General Re
Corp., HCC Insurance Holdings, Inc., MBIA Inc., Markel Corp., MGIC Investment
Corp., Progressive Corp. and Vesta Insurance Group Inc. (collectively, the
"Selected Companies"). Salomon Smith Barney compared, among other things, market
values of the Selected Companies as multiples of, among other things, estimated
calendar 1997 and calendar 1998 net operating income computed in accordance with
GAAP, and GAAP book value as of September 30, 1997. Net income projections for
the Selected Companies, American Bankers and
 
                                       29

<PAGE>   38
 
AIG were based on estimates of selected investment banking firms. All multiples
were based on closing stock prices as of December 19, 1997. Applying a range of
selected multiples for the Selected Companies of estimated calendar 1997 and
1998 GAAP net operating income and GAAP book value as of September 30, 1997, of
18.0x to 22.0x, 16.0x to 19.0x and 2.20x to 3.00x, respectively, to
corresponding financial data of American Bankers resulted in equity reference
ranges for American Bankers of approximately $42.46 to $49.88 per share on a
fully diluted basis, as compared to the $47.00 per share value provided in the
Merger. Salomon Smith Barney also compared the relationship between the price to
book value multiples and projected return on average equity of the Selected
Companies with that of American Bankers.
 
     No transaction, company or business used as a comparison in the "Selected
Insurance Transactions Analysis" or "Selected Public Company Analysis" is
identical to American Bankers, AIG or the Merger. Accordingly, an analysis of
the results of the foregoing is not entirely mathematical; rather, it involves
complex considerations and judgments concerning differences in financial and
operating characteristics and other factors that could affect the acquisition,
public trading or other values of the Selected Transactions, Selected Companies
or the business segment, company or transaction to which they are being
compared.
 
     Discounted Dividend Analysis.  Salomon Smith Barney performed a discounted
dividend analysis of the projected dividendable net income of American Bankers
for fiscal years 1998 through 2002, based on internal estimates of the
management of American Bankers. The range of the estimated terminal value for
American Bankers at the end of the five-year period was calculated by applying
terminal multiples ranging from 15.0x to 17.0x to American Bankers' projected
2003 net income, representing American Bankers' estimated value at December 31,
2002. The terminal value of American Bankers and projected dividendable net
income of American Bankers for the five-year period were discounted to December
31, 1997 using rates ranging from 11% to 15%. This analysis resulted in an
equity reference range for American Bankers of approximately $33.30 to $44.17
per share on a fully diluted basis, as compared to the $47.00 per share value
provided in the Merger.
 
     Pro Forma Merger Analysis.  Salomon Smith Barney analyzed certain pro forma
effects resulting from the Merger, including, among other things, the impact of
the Merger on the projected earnings per share ("EPS") of AIG for the fiscal
years ending 1998 through 2002, based on internal estimates of the management of
American Bankers and estimates of selected investment banking firms. The results
of the pro forma merger analysis suggested that the Merger could be accretive to
AIG's EPS in each of the fiscal years analyzed. The actual results achieved by
AIG following the Merger may vary from projected results and the variations may
be material.
 
     Other Factors and Comparative Analyses.  In rendering its opinion, Salomon
Smith Barney considered certain other factors and conducted certain other
comparative analyses, including, among other things, a review of: (i) the
historical and projected financial results of American Bankers and AIG; (ii) the
history of trading prices and volume for the Common Stock and AIG Common Stock;
(iii) premiums paid in selected stock-for-stock transactions in the insurance
industry; and (iv) the pro forma ownership of the combined company.
 
     Pursuant to the terms of Salomon Smith Barney's engagement, American
Bankers has agreed to pay Salomon Smith Barney for its services in connection
with the Merger an aggregate financial advisory fee of approximately $12.1
million, a substantial portion of which is contingent upon the consummation of
the Merger. American Bankers has also agreed to reimburse Salomon Smith Barney
for reasonable travel and other reasonable out-of-pocket expenses incurred by
Salomon Smith Barney in performing its services, including the reasonable fees
and expenses of its legal counsel, and to indemnify Salomon Smith Barney and
related persons against certain liabilities, including liabilities under the
federal securities laws, arising out of Salomon Smith Barney's engagement.
 
     Salomon Smith Barney has advised American Bankers that, in the ordinary
course of business, Salomon Smith Barney and its affiliates may actively trade
or hold the securities of American Bankers and AIG for their own account or for
the account of customers and, accordingly, may at any time hold a long or short
position in such securities. Salomon Smith Barney has in the past provided
certain investment banking services to American Bankers and AIG unrelated to the
Merger, for which services Salomon Smith Barney
 
                                       30

<PAGE>   39
 
has received compensation. In addition, Salomon Smith Barney and its affiliates
(including Travelers Group Inc. and its affiliates) may maintain relationships
with American Bankers and AIG.
 
     Salomon Smith Barney is a nationally recognized investment banking firm and
was selected by American Bankers based on Salomon Smith Barney's experience,
expertise and familiarity with American Bankers and its business. Salomon Smith
Barney regularly engages in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings, competitive
bids, secondary distributions of listed and unlisted securities, private
placements and valuations for estate, corporate and other purposes.
 
     THE FULL TEXT OF THE WRITTEN OPINION OF SALOMON SMITH BARNEY DATED DECEMBER
21, 1997, WHICH SETS FORTH THE ASSUMPTIONS MADE, MATTERS CONSIDERED AND
LIMITATIONS ON THE REVIEW UNDERTAKEN, IS ATTACHED HERETO AS APPENDIX IV AND IS
INCORPORATED HEREIN BY REFERENCE. SALOMON SMITH BARNEY HAS CONSENTED TO THE USE
OF ITS OPINION IN THIS PROXY STATEMENT/PROSPECTUS. HOLDERS OF COMMON STOCK AND
PREFERRED STOCK ARE URGED TO READ THIS OPINION CAREFULLY IN ITS ENTIRETY.
SALOMON SMITH BARNEY'S OPINION IS DIRECTED TO THE AMERICAN BANKERS BOARD AND
RELATES ONLY TO THE FAIRNESS OF THE COMMON STOCK MERGER CONSIDERATION AND
PREFERRED STOCK MERGER CONSIDERATION FROM A FINANCIAL POINT OF VIEW TO HOLDERS
OF COMMON STOCK AND TO HOLDERS OF PREFERRED STOCK, RESPECTIVELY, DOES NOT
ADDRESS ANY OTHER ASPECT OF THE MERGER OR RELATED TRANSACTIONS AND DOES NOT
CONSTITUTE A RECOMMENDATION TO ANY SHAREHOLDER AS TO HOW SUCH SHAREHOLDER SHOULD
VOTE AT THE SPECIAL MEETINGS OR AS TO WHETHER ANY HOLDER OF COMMON STOCK SHOULD
ELECT TO RECEIVE CASH OR AIG COMMON STOCK PURSUANT TO THE MERGER. THE SUMMARY OF
THE OPINION OF SALOMON SMITH BARNEY SET FORTH IN THIS PROXY STATEMENT/PROSPECTUS
IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF SUCH OPINION.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER
 
     The following summary discusses the material federal income tax
consequences of the Merger. The summary is based upon the Internal Revenue Code
of 1986, as amended (the "Code"), applicable Treasury regulations thereunder and
administrative rulings and judicial authority as of the date hereof. All of the
foregoing are subject to change, possibly with retroactive effect, and any such
change could affect the continuing validity of the discussion. The discussion
assumes that holders of shares of Common Stock and Preferred Stock hold such
shares as capital assets. Further, the discussion does not address the tax
consequences that may be relevant to a particular shareholder subject to special
treatment under certain federal income tax laws, such as dealers in securities,
banks, insurance companies, tax-exempt organizations, non-United States persons,
shareholders who acquired shares of Common Stock or Preferred Stock through the
exercise of options, grants of performance shares under American Bankers'
equity-based compensation plans or otherwise as compensation or through a
tax-qualified retirement plan or holders that actually or constructively own
more than 1% of the total outstanding common stock of AIG. This discussion does
not address any consequences arising under the laws of any state, locality or
foreign jurisdiction. Shareholders subject to such special treatment are urged
to consult their own federal income tax advisors.
 
     Neither AIG nor American Bankers has requested a ruling from the Internal
Revenue Service (the "IRS") with regard to any of the federal income tax
consequences of the Merger and the opinions of counsel as to such federal income
tax consequences set forth below are not binding on the IRS.
 
     (i) General.  It is intended that the Merger constitute a "reorganization"
pursuant to Section 368(a) of the Code, unless the Merger is restructured as
described below under "The Merger Agreement -- Alternative Transaction
Structure". If the Merger is not so restructured, the respective obligations of
the parties to consummate the Merger are conditioned on (a) the receipt by AIG,
prior to the effective date of the Registration Statement, of an opinion of
Sullivan & Cromwell to the effect that the Merger will qualify as a
 
                                       31

<PAGE>   40
 
"reorganization" within the meaning of Section 368(a) of the Code and that each
of AIG, American Bankers and AIGF will be a party to the "reorganization" within
the meaning of Section 368(b) of the Code, (b) the reconfirmation of such
opinion by Sullivan & Cromwell as of the Closing Date, (c) the receipt by
American Bankers, prior to the effective date of the Registration Statement, of
an opinion of Jorden Burt Berenson & Johnson LLP to the effect that the Merger
will qualify as a "reorganization" within the meaning of Section 368(a) of the
Code and that each of AIG, American Bankers and AIGF will be a party to the
"reorganization" within the meaning of Section 368(b) of the Code, and (d) the
reconfirmation of such opinion by Jorden Burt Berenson & Johnson LLP as of the
Closing Date. Such opinions will be based upon, among other things (i)
representations of American Bankers, AIG and certain shareholders of American
Bankers customarily given in transactions of this type and (ii) the assumption
that the Merger will be consummated in accordance with the terms of the Merger
Agreement and will not be restructured as described below in "The Merger
Agreement -- Alternative Transaction Structure". THE FEDERAL INCOME TAX
CONSEQUENCES OF THE MERGER AS SO RESTRUCTURED WOULD DIFFER MATERIALLY FROM THOSE
DESCRIBED IN THIS DISCUSSION. SEE "THE MERGER AGREEMENT -- ALTERNATIVE
TRANSACTION STRUCTURE" FOR A DISCUSSION OF THE FEDERAL INCOME TAX CONSEQUENCES
OF THE MERGER AS SO RESTRUCTURED.
 
     The discussion below summarizes the material federal income tax
consequences of the Merger, assuming that the Merger will qualify as a
"reorganization" within the meaning of Section 368(a) of the Code.
 
     (ii) Consequences to Holders of Preferred Stock.  No gain or loss will be
recognized by holders of Preferred Stock on the surrender of their shares of
Preferred Stock in exchange for shares of AIG Series C Preferred Stock pursuant
to the Merger. The aggregate tax basis of the shares of AIG Series C Preferred
Stock received in the Merger will be the same as the aggregate tax basis of the
shares of Preferred Stock surrendered in exchange therefor. The holding period
of the shares of AIG Series C Preferred Stock received will include the holding
period of shares of Preferred Stock surrendered in exchange therefor.
 
     (iii) Consequences to Holders of Common Stock.
 
          (a) Holders Receiving Only AIG Common Stock.  No gain or loss will be
     recognized by a holder of Common Stock as a result of the surrender of
     shares of Common Stock in exchange for shares of AIG Common Stock pursuant
     to the Merger, if such holder receives no cash pursuant to the Merger
     (except as discussed below with respect to cash received in lieu of
     fractional shares of AIG Common Stock). The aggregate tax basis of the
     shares of AIG Common Stock received in the Merger (including any fractional
     shares of AIG Common Stock deemed received) will be the same as the
     aggregate tax basis of the shares of Common Stock surrendered in exchange
     therefor. The holding period of the shares of AIG Common Stock received
     will include the holding period of shares of Common Stock surrendered in
     exchange therefor.
 
          (b) Holders Receiving Only Cash.  A holder of Common Stock that is not
     also a holder of Preferred Stock and that does not receive any AIG Common
     Stock pursuant to the Merger will recognize gain or loss equal to the
     difference between the amount of cash received and the holder's adjusted
     tax basis in the shares of Common Stock exchanged in the Merger. Such gain
     or loss will generally be a capital gain or loss, and will generally be a
     long-term capital gain or loss to the extent that, at the Effective Time,
     the holder has a holding period for federal income tax purposes in such
     Common Stock of more than one year. For an individual holder, long-term
     capital gain is generally subject to a maximum federal income tax rate of
     28% in respect of property with a holding period of more than one year and
     to a maximum rate of 20% in respect of property with a holding period of
     more than 18 months.
 
          (c) Holders Receiving Both Cash and AIG Common Stock or AIG Series C
     Preferred Stock.  If a holder of Common Stock receives both AIG Common
     Stock and cash (other than cash in lieu of a fractional interest in AIG
     Common Stock) in the Merger, or if a holder of Common Stock is also a
     holder of Preferred Stock and receives cash (other than cash in lieu of a
     fractional interest in AIG Common Stock) in the Merger, whether or not such
     holder also receives AIG Common Stock in the Merger, such holder will
     recognize gain equal to the lesser of (i) the amount of cash received
     (other than cash in lieu of a fractional interest in AIG Common Stock) and
     (ii) the amount by which the sum of the amount of cash received (other than
     cash in lieu of a fractional interest in AIG Common Stock) and the value of
     the AIG Common Stock received (including any fractional shares of AIG
     Common Stock
 
                                       32

<PAGE>   41
 
     deemed received), determined as of the Effective Time, exceeds the holder's
     adjusted tax basis in the shares of Common Stock exchanged in the Merger.
     Such a holder will not recognize loss. Under Section 356 of the Code, such
     gain will generally be capital gain unless the holder's exchange of Common
     Stock for cash and AIG Common Stock "has the effect of the distribution of
     a dividend" after giving effect to the constructive ownership rules of the
     Code (which provide that a holder may be treated as owning stock actually
     owned, and in some cases constructively owned, by certain individuals or
     entities related to the holder and stock that the holder had the right to
     acquire by the exercise of an option or conversion right, including the
     conversion rights with respect to the Preferred Stock and the AIG Series C
     Preferred Stock). Under these rules, a holder is treated as exchanging all
     his Common Stock for AIG Common Stock and receiving cash in redemption of a
     portion of such AIG Common Stock deemed received. Such gain should
     generally be capital gain to a holder of Common Stock that, following the
     Merger, actually or constructively owns only a small percentage of the
     total outstanding AIG Common Stock. The capital gain recognized will be
     long term capital gain to the extent that, at the Effective Time, the
     holder has a holding period for federal income tax purposes in the Common
     Stock exchanged in the Merger of more than one year. For an individual
     holder, long-term capital gain is generally subject to a maximum tax rate
     of 28% in respect of property with a holding period of more than one year
     and to a maximum rate of 20% in respect of property with a holding period
     of more than 18 months. The aggregate tax basis to such a holder of the
     shares of AIG Common Stock received in the Merger (including any fractional
     shares of AIG Common Stock deemed received) will be the same as the
     aggregate tax basis of the shares of Common Stock surrendered in exchange
     therefor in the Merger, increased by the amount of gain recognized and
     reduced by the amount of cash received. The holding period of the shares of
     AIG Common Stock received will include the holding period of shares of
     Common Stock surrendered in exchange therefor.
 
          (d) Fractional Shares.  If a holder of shares of Common Stock receives
     cash in lieu of a fractional share interest in AIG Common Stock in the
     Merger, such fractional share interest will be treated as having been
     distributed to the holder, and such cash amount will be treated as received
     in redemption of the fractional share interest. Under present IRS ruling
     policy, the holder will generally recognize capital gain or loss equal to
     the cash amount received for the fractional share of AIG Common Stock
     reduced by the portion of the holder's tax basis in shares of Common Stock
     surrendered that is allocable to the fractional share interest in AIG
     Common Stock. The capital gain or loss will be long term capital gain or
     loss if the holder's holding period in the fractional share interest for
     federal income tax purposes is more than one year.
 
          (e) Backup Withholding and Information Reporting.  Payments of cash to
     a holder surrendering shares of Common Stock will be subject to information
     reporting and "backup" withholding (whether or not the holder also receives
     AIG Common Stock) at a rate of 31% of the cash payable to the holder,
     unless the holder furnishes its taxpayer identification number in the
     manner prescribed in applicable Treasury Regulations, certifies that such
     number is correct, certifies as to no loss of exemption from backup
     withholding and meets certain other conditions. See the Election Form and
     Letter of Transmittal accompanying this Proxy Statement/Prospectus for a
     discussion of the certification requirements to establish an exemption from
     backup withholding. Any amounts withheld from payments to a holder under
     the backup withholding rules will be allowed as a refund or credit against
     the holder's United States federal income tax liability, provided the
     required information is furnished to the IRS.
 
     THE PRECEDING DISCUSSION DOES NOT PURPORT TO BE A COMPLETE ANALYSIS OR
DISCUSSION OF ALL POTENTIAL TAX EFFECTS RELEVANT TO THE MERGER. THUS, AMERICAN
BANKERS SHAREHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE
SPECIFIC TAX CONSEQUENCES TO THEM OF THE MERGER, INCLUDING TAX RETURN REPORTING
REQUIREMENTS, THE APPLICABILITY AND EFFECT OF FEDERAL, STATE, LOCAL, AND OTHER
APPLICABLE TAX LAWS AND THE EFFECT OF ANY PROPOSED CHANGES IN THE TAX LAWS.

REGULATORY FILINGS AND APPROVALS
 
     Antitrust.  Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976,
as amended (the "HSR Act"), and the rules promulgated thereunder by the Federal
Trade Commission (the "FTC"), the Merger cannot be consummated until
notifications have been given and certain information has been furnished to the
FTC and the Antitrust Division of the Department of Justice (the "Antitrust
Division") and specified waiting period requirements have been satisfied. AIG
and American Bankers each filed notification and report forms under the HSR Act
with the FTC and the Antitrust Division on January 20, 1998. The companies
expect that the waiting period will expire on February 19, 1998 unless
terminated earlier.
 
     At any time before or after consummation of the Merger, the Antitrust
Division or the FTC or any state could take such action under the antitrust laws
as it deems necessary or desirable in the public interest, including seeking to
enjoin the consummation of the Merger or seeking divestiture of substantial
assets of AIG or American Bankers. Such action could include seeking to enjoin
the consummation of the Merger or seeking divestiture of American Bankers or
businesses of AIG or American Bankers by AIG. Private parties may also seek to
take legal action under the antitrust laws under certain circumstances.
 
     In addition, AIG has requested and has received an advance ruling
certificate under The Competition Act of Canada.
 
     Insurance.  The Merger is also subject to the receipt of necessary
approvals from various state and foreign insurance regulatory authorities. In
December 1997 and January 1998, AIG filed an Application for Approval of
Acquisition of Control of or Merger with a Domestic Insurer (Form A) or a
comparable application (each, a "Form A") in a total of six states and Puerto
Rico where such filings were required and made filings in various foreign
jurisdictions. The insurance laws and regulations of certain of the states where
such Form A filings were made require hearings by the state insurance
departments before deciding whether to grant approval of an acquisition
described in a Form A filing. In certain of the states that do not require a
hearing prior to approval, AIG would be entitled to a hearing in the event the
state insurance department proposed not to grant the approval. The approvals
described in this paragraph are pending as of the date hereof.
 
     In addition to the Form A filings, in January 1998 AIG filed
Pre-Acquisition Notification Forms Regarding the Potential Competitive Impact of
a Proposed Merger or Acquisition by a Non-Domiciliary Insurer Doing Business in
this State or by a Domestic Insurer (Form E) or a comparable form (each, a "Form
E") in 21 states where such filings were required. The Form E filings are
generally reviewed within 30 days after filing with the state insurance
departments, which may request additional information on the competitive impact
of a proposed acquisition. The 30 day time period will expire on or about
February 25, 1998. The approvals described in this paragraph are pending in 20
states as of the date hereof.
 
     There can be no assurance that the required regulatory approvals described
above will be received or, if received, the timing and the terms and conditions
thereof.
 
RESALE OF AIG SERIES C PREFERRED STOCK AND AIG COMMON STOCK
 
     All shares of AIG Series C Preferred Stock received by holders of Preferred
Stock and all shares of AIG Common Stock received by holders of Common Stock in
the Merger will be freely transferable, except that shares of AIG Series C
Preferred Stock and AIG Common Stock received by persons who are deemed to be
"affiliates" (as such term is defined under the Securities Act) of American
Bankers at the time of the Special Meetings may be resold by them only in
transactions permitted by the resale provisions of Rule 145 promulgated under
the Securities Act (or Rule 144 in the case of such persons who become
affiliates of AIG) or as otherwise permitted under the Securities Act. Persons
who may be deemed to be affiliates of American Bankers or AIG generally include
individuals or entities that control, are controlled by, or are under common
control with, such party and may include certain officers and directors of such
party as well as principal shareholders of such party. The Merger Agreement
requires American Bankers to use its reasonable best efforts to cause each of
its affiliates to execute a written agreement (an "Affiliates Letter") to the
effect that such person will not offer to sell, transfer, or otherwise dispose
of any of the shares of AIG Series C Preferred
 
                                       34

<PAGE>   43
 
Stock or AIG Common Stock issued to such person in or pursuant to the Merger
unless such sale, transfer or other disposition (a) has been registered under
the Securities Act, (b) is made in conformity with Rule 145 under the Securities
Act or (c) is exempt from registration under the Securities Act.
 
MANAGEMENT AND OPERATIONS FOLLOWING THE MERGER
 
     Following the Merger, American Bankers will continue its operations as a
wholly-owned subsidiary of AIG. The membership of the American Bankers Board
will remain unchanged as a result of the Merger, except that two additional
members designated by AIG will be added to the American Bankers Board. The
officers of American Bankers also will remain unchanged as a result of the
Merger. Messrs. Gaston and Denison have entered into employment agreements with
American Bankers to be effective upon consummation of the Merger. See "Related
Agreements and Transactions -- Employment Agreements." The shareholders of
American Bankers will become shareholders of AIG, and their rights as
shareholders will be governed by AIG's Amended and Restated Certificate of
Incorporation (the "AIG Certificate") and AIG's bylaws (the "AIG Bylaws") and
the laws of the State of Delaware. See "Comparative Rights of Common
Shareholders."
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
     In considering the recommendation of the American Bankers Board with
respect to the Merger, American Bankers' shareholders should be aware that
certain members of management of American Bankers and members of the American
Bankers Board have interests in the Merger that are different from, or in
addition to, the interests of the shareholders of American Bankers generally.
The American Bankers Board was aware of such interests and considered them,
among other matters, in approving the Merger Agreement and the transactions
contemplated thereby.
 
     Employment Agreements.  American Bankers has entered into employment
agreements with Mr. Gerald Gaston and Mr. Floyd Denison. Each of such employment
agreements becomes effective commencing on the Effective Time and continues for
five years. Pursuant to such employment agreements, Messrs. Gaston and Denison
will receive severance payments if they are terminated under certain
circumstances. The employment agreements are described more fully below in
"Related Agreements and Transactions -- Employment Agreements." Assuming that
Messrs. Gaston and Denison terminated their employment immediately following the
Merger for Good Reason or without cause (as defined in such employment
agreements), the estimated amounts payable to Mr. Gaston and Mr. Denison
pursuant to such employment agreements as a result of such terminations of
employment would be $4.8 million and $1.5 million, respectively.
 
     Severance Agreements.  American Bankers is currently a party to severance
agreements with various of its executive officers. Pursuant to the Merger
Agreement, American Bankers has agreed to use its best efforts to cause such
executive officers to agree to amendments to such severance agreements. Pursuant
to such amended severance agreements, certain executive officers will receive
severance payments if they are terminated under certain circumstances. The
severance agreements, and the amendments thereto, are described more fully below
in "Related Agreements and Transactions -- Amendments to Severance Agreements."
Assuming each such executive officer terminated employment immediately following
the Merger for Good Reason or under certain other circumstances (as defined in
the amended severance agreements), the estimated aggregate amount payable to
such officers pursuant to the amended severance agreements as a result of such
terminations of employment would be approximately $23.2 million (which includes
amounts payable to Messrs. Gaston and Denison pursuant to the employment
agreements described above).
 
     Stock Options and Restricted Stock.  American Bankers maintains various
plans pursuant to which stock option awards and restricted stock awards are made
to its executive officers. Under the 1994 Senior Management Stock Option Plan
(the "1994 Senior Plan"), the 1991 Stock Option/Restricted Stock Award Plan (the
"1991 Award Plan") and the 1991 Stock Incentive Compensation Plan (the "1991
Incentive Plan"), upon the exercise of a stock option, the optionee is entitled
to receive shares of Common Stock which are subject to restrictions on transfer
("Restricted Stock") (which, in the case of the 1994 Senior Plan and the 1991
Award Plan, are in addition to non-restricted shares of Common Stock received
upon such exercise).
 
                                       35

<PAGE>   44
 
Pursuant to the terms of the 1994 Senior Plan, the 1991 Award Plan and the 1991
Incentive Plan, upon a "change in control" (as defined in such plans), the
restrictions applicable to shares of Restricted Stock then held by executive
officers on account of the exercise of options under such plans will lapse. The
Merger will constitute a change in control under such plans and, accordingly,
the restrictions on shares of Restricted Stock then held by executive officers
on account of the exercise of options under such plans will lapse.
 
     American Bankers has also granted options to purchase Common Stock under
the 1997 Equity Incentive Plan (the "1997 Incentive Plan"). Pursuant to the
award agreements entered into under the 1997 Incentive Plan, all outstanding
stock options will become fully vested and exercisable upon a "change in
control" (as defined under the 1997 Incentive Plan). Upon the exercise of an
option under the 1997 Incentive Plan, the optionee is entitled to receive shares
of Restricted Stock (as well as non-restricted shares of Common Stock). The
Merger will constitute a change in control under the 1997 Incentive Plan and,
accordingly, all unvested options under such plan will become immediately vested
and exercisable upon consummation of the Merger and shares of Restricted Stock
then held on account of the exercise of options under the 1997 Incentive Plan
will become fully vested.
 
     The treatment in the Merger of outstanding options is described in more
detail in "The Merger Agreement -- Treatment of Stock Options."
 
     Mr. James F. Jorden, a director of American Bankers, is the Managing Senior
Partner of the law firm of Jorden Burt Berenson & Johnson LLP, which provides
legal services to American Bankers, including in connection with the Merger, for
which it will receive compensation.
 
ABSENCE OF APPRAISAL RIGHTS
 
     Under Florida law, holders of Preferred Stock and Common Stock are not
entitled to dissenters' or appraisal rights in connection with the Merger
because the Preferred Stock and the Common Stock are listed on the NYSE.
 
ACCOUNTING TREATMENT
 
     The Merger will be accounted for under the "purchase" method of accounting
whereby the purchase price paid by AIG will be allocated based on fair values of
assets acquired and liabilities assumed. Such allocations will be made based
upon valuations and other studies that have not been finalized. The excess of
such purchase price over the amounts so allocated will be treated as goodwill.
 
PUBLIC TRADING MARKETS
 
     The Preferred Stock and Common Stock currently are listed on the NYSE under
the symbols "ABI 3 1/8 Pfd" and "ABI," respectively. Upon consummation of the
Merger, the Preferred Stock and Common Stock will be delisted from the NYSE and
deregistered under the Exchange Act (unless the alternative transaction
structure described below in "The Merger Agreement -- Alternative Transaction
Structure" is utilized, in which case the Preferred Stock will remain
outstanding and listed on the NYSE and registered under the Exchange Act). AIG
Common Stock currently is listed on the NYSE under the symbol "AIG." Application
will be made for the listing on the NYSE of the shares of AIG Common Stock and
AIG Series C Preferred Stock to be issued in the Merger. The listings on the
NYSE are a condition to the consummation of the Merger. See "The Merger
Agreement -- Conditions of the Proposed Merger."
 
                              RECENT DEVELOPMENTS
 
     On January 27, 1998, Cendant publicly announced a proposal to acquire
American Bankers for $58 per share of Common Stock, to be paid in cash and
common stock of Cendant. Such proposal was communicated in a letter (attached as
Appendix VII to this Proxy Statement/Prospectus) to the American Bankers Board
from Henry R. Silverman, the President and Chief Executive Officer, and Walter
A. Forbes, the Chairman, of Cendant. Also on January 27, 1998, American Bankers
announced that the American Bankers Board would review Cendant's proposal in due
course, and requested that holders of Common Stock not take any action
 
                                       36

<PAGE>   45
 
until such time as the American Bankers Board responds to Cendant's proposal. In
connection with its proposal, Cendant commenced litigation against American
Bankers, the members of the American Bankers Board, AIG and AIGF in the United
States District Court for the Southern District of Florida challenging as
breaches of the fiduciary duties of members of the American Bankers Board, among
other things, certain provisions of the Merger Agreement and the Stock Option
Agreement, and asserting that AIG failed to disclose certain interests of AIG's
Chairman and Chief Executive Officer in AIG Common Stock (and referring to
information on such matters included in certain of AIG's prior filings with the
Commission). The complaint in connection with the litigation seeks, among other
things, an order enjoining implementation or effectuation of the Merger
Agreement unless and until the conduct alleged to constitute the breaches of
fiduciary duties is remedied. Since the commencement of the Cendant litigation,
a number of substantially identical suits have been brought by American Bankers'
shareholders in the Federal and state courts in Miami, asserting essentially the
same claims against the same defendants as the Cendant litigation. In each of
the actions, the named plaintiff is seeking to have his or her claims
adjudicated on behalf of a class of all American Bankers shareholders and to
recover unspecified damages in addition to, or in lieu of, injunctive and other
equitable relief.
 
     Subsequent to the announcement of Cendant's proposal, AIG on January 27,
1998 sent a notice to American Bankers exercising its option to purchase the
8,265,626 shares of Common Stock issuable under the Stock Option Agreement. The
consummation of such purchase is subject to applicable regulatory approvals.
Issuance of the shares subject to the Stock Option Agreement may delay or make
more difficult an acquisition of American Bankers by a person other than AIG.
See "Related Agreements and Transactions -- Stock Option Agreement."
 
     On January 28, 1998, Cendant commenced a tender offer seeking to purchase
23,501,260 shares of Common Stock, subject to the terms and conditions stated
therein, at $58 per share in cash.

                              THE MERGER AGREEMENT
 
     The following describes certain aspects of the proposed Merger, including
material provisions of the Merger Agreement. The following description of the
Merger does not purport to be complete and is qualified in its entirety by
reference to the Merger Agreement, which is attached as Appendix I to this Proxy
Statement/Prospectus and is incorporated herein by reference. Holders of
Preferred Stock and Common Stock are urged to read the Merger Agreement
carefully. Capitalized terms used in this section or elsewhere in this Proxy
Statement/Prospectus but not defined in this Proxy Statement/Prospectus shall
have the meanings attributed to them in the Merger Agreement.
 
GENERAL; THE ELECTION; MERGER CONSIDERATION
 
     The terms of the Merger are set forth in the Merger Agreement that was
approved by the American Bankers Board and the AIG Board and signed by American
Bankers, AIG and AIGF on December 21, 1997, amended and restated by the parties
as of January 7, 1998, and amended by Amendment No. 1 thereto dated as of
January 28, 1998, a copy of which is attached hereto as Appendix I. Pursuant to
the Merger Agreement, and on the terms and conditions set forth therein, at the
Effective Time, American Bankers will be merged with and into AIGF. AIGF will be
the surviving corporation in the Merger (the "Surviving Corporation") and will
succeed to the business of American Bankers and will assume the name American
Bankers Insurance Group, Inc. As a result of the Merger, each share of Preferred
Stock issued and outstanding immediately prior to the Effective Time (other than
Excluded Preferred Shares) shall be converted into, and become exchangeable for,
one share of AIG Series C Preferred Stock (the "Preferred Stock Merger
Consideration"). The AIG Series C Preferred Stock will contain terms
substantially similar to the terms of the Preferred Stock (after making the
conversion adjustments required to be made pursuant to the American Bankers
Articles) and will be convertible into AIG Common Stock. See "Description of AIG
Capital Stock -- AIG Series C Preferred Stock." As a result of the Merger, each
share of Common Stock issued and outstanding immediately prior to the Effective
Time (as hereinafter defined) (other than Excluded Common Shares) shall be
converted into, and become exchangeable for, such amount of cash, portion of a
share of AIG Common Stock or combination thereof as described in the next four
paragraphs.
 
     Each holder of Common Stock will be entitled to elect with respect to all
or any portion of the shares of Common Stock held by such holder to have such
shares converted at the Effective Time into the right to receive the Cash
Election Merger Consideration (as hereinafter defined) (the "Cash Election") or
the Stock Election Merger Consideration (as hereinafter defined) (the "Stock
Election"). The form for making the Cash Election or Stock Election (the
"Election Form") is being mailed to holders of Common Stock on or about February
2, 1998, together with this Proxy Statement/Prospectus. Each holder may make a
Cash Election or Stock Election by properly completing, signing and submitting
the Election Form to the Exchange Agent, by 5:00 p.m., New York City time, on
the third trading day prior to the date of the consummation of the Merger (the
"Election Deadline"). The Election Deadline will not occur any earlier than 5:00
p.m., New York City time, on March 3, 1998. AIG will publicly announce the
Election Deadline not later than 10:00 a.m. on the trading day preceding the
date on which the Election Deadline will occur. To be effective, the Election
Form must be accompanied by the certificates representing the shares of Common
Stock as to which an election is being made or an appropriate guarantee of
delivery by a commercial bank or trust company in the United States or a member
of a registered national securities exchange or the National Association of
Securities Dealers, Inc. ("NASD"). An Election Form which is not effective shall
be treated as if no election had been made with respect to the shares of Common
Stock covered by such Election Form and any holder who does not submit an
effective Election Form shall receive the Non-Election Merger Consideration (as
hereinafter defined). AIG will have the discretion, which it may delegate in
whole or in part to the Exchange Agent, to determine whether Election Forms have
been properly completed, signed and submitted or revoked and to disregard
immaterial defects in Election Forms. The decisions of AIG or, if delegated, the
Exchange Agent shall be conclusive and binding. Neither AIG, AIGF nor the
Exchange Agent will be under any obligation to notify any person of any defect
in an Election Form submitted to the Exchange Agent. The Exchange Agent shall
also make all computations contemplated by Section 4.1(a) of the Merger
Agreement, and all such computations shall be conclusive and binding on the
holders of Common Stock in the absence of
 
                                       38

<PAGE>   47
 
manifest error. AIG and American Bankers each shall use its best efforts to make
the Election Form available to all persons who become holders of record of
Common Stock during the period between the Record Date and the Election
Deadline. A properly completed Election Form must be received by the Exchange
Agent by the Election Deadline in order to be effective. Any Election Form may
be revoked by written notice or a later dated Election Form received by the
Exchange Agent prior to the Election Deadline.
 
     Each share of Common Stock for which the holder of such shares has failed
to make an effective Cash Election or Stock Election shall be converted into,
and become exchangeable for, that portion of a share of AIG Common Stock equal
to the lesser of (i) .4495 (the "Maximum Exchange Ratio") and (ii) the decimal
derived by dividing $47.00 by the average of the closing prices per share of AIG
Common Stock as reported on the NYSE composite transactions reporting system (as
reported in the New York City edition of The Wall Street Journal) for the ten
trading days ending on the third trading day prior to the date of the
consummation of the Merger (the "Base Period Stock Price"); provided, however,
if the Base Period Stock Price is below $104.5625, AIG shall elect to either (i)
pay a cash amount equal to the Per Share Cash Top-Up Amount (as hereinafter
defined) (provided that AIG may not elect to pay the cash amount contemplated by
this clause (i) if the aggregate cash amount so paid would exceed the
Non-Election Cash Pool (as hereinafter defined)) or (ii) (x) increase the
Maximum Exchange Ratio (the "Adjusted Maximum Exchange Ratio") up to a decimal
such that the product of the Adjusted Maximum Exchange Ratio times the Base
Period Stock Price (the "Product") equals or is less than $47.00 and (y) if the
Product is less than $47.00, pay a cash amount equal to the difference between
$47.00 and such Product (provided that AIG may not elect to pay such an
aggregate amount of cash pursuant to this clause (ii) which would exceed the
NonElection Cash Pool (as hereinafter defined)). The foregoing payments shall be
referred to herein as the "Non-Election Merger Consideration." For purposes
hereof, "Per Share Cash Top-Up Amount" means the greater of (i) $0 and (ii)(x)
$47.00 minus (y) the product of (A) the Base Period Stock Price and (B) the
Maximum Exchange Ratio; "Non-Election Cash Pool" means an amount of cash equal
to the Maximum Cash Pool (as hereinafter defined) minus the aggregate amount of
cash paid in the Merger to the holders of shares of Common Stock that make a
Cash Election; and "Maximum Cash Pool" means an amount of cash equal to .499
multiplied by the sum of the Non-Election Merger Consideration, the Cash
Election Merger Consideration (as hereinafter defined) and the Stock Election
Merger Consideration (as hereinafter defined) (collectively, the "Common Stock
Merger Consideration" and, together with the Preferred Stock Merger
Consideration, the "Merger Consideration"), calculated for purposes of this
definition based on the closing price of AIG Common Stock on the NYSE composite
transaction reporting system on the trading day immediately preceding the day
the Merger is consummated.
 
     Each share of Common Stock for which the holder of such share has made a
Cash Election shall be converted into, and become exchangeable for, $47.00 in
cash (the "Cash Election Merger Consideration"), provided that in no event shall
holders of shares of Common Stock who have made a Cash Election be entitled to
receive an aggregate amount of cash in excess of the Maximum Cash Pool. In the
event that Cash Elections are submitted with respect to an aggregate number of
shares of Common Stock which, except for the limitation imposed by the Maximum
Cash Pool, would require AIG to pay cash in the aggregate in excess of the
Maximum Cash Pool, a pro rata portion of such shares of Common Stock (rounded
down to the nearest whole share of Common Stock) shall be converted into the
right to receive the Cash Election Merger Consideration, which proration as to
each shareholder shall be based upon the ratio of the (i) Maximum Cash Pool to
(ii) the aggregate number of shares of Common Stock with respect to which Cash
Elections are submitted multiplied by $47.00. All shares of Common Stock for
which a Cash Election is made but which are not converted into the right to
receive the Cash Election Merger Consideration shall be converted into the right
to receive the Stock Election Merger Consideration. BECAUSE OF THE LIMITATIONS
DESCRIBED ABOVE, THERE CAN BE NO ASSURANCE THAT A HOLDER WHO ELECTS TO RECEIVE
CASH WILL IN FACT RECEIVE CASH FOR THE FULL AMOUNT OF CONSIDERATION INTO WHICH
HIS COMMON STOCK IS CONVERTED IN THE MERGER.
 
     Each share of Common Stock for which the holder of such share has made a
Stock Election shall be converted into, and become exchangeable for, that
portion of a share of AIG Common Stock equal to the lesser of (i) the Maximum
Exchange Ratio and (ii) the decimal derived by dividing $47.00 by the Base
Period Stock Price; provided, however, if the Base Period Stock Price is below
$104.5625, AIG shall elect to
 
                                       39

<PAGE>   48
 
either (i) pay a cash amount equal to the Per Share Cash Top-Up Amount (provided
that AIG may not elect to pay the cash amount contemplated by this clause (i) if
the aggregate cash amount paid would exceed the Stock Election Cash Pool (as
hereinafter defined)) or (ii) (x) establish the Adjusted Maximum Exchange Ratio
such that the Product equals or is less than $47.00 and (y) if the Product is
less than $47.00, pay a cash amount equal to the difference between $47.00 and
such Product (provided that AIG may not elect to pay an aggregate amount of cash
pursuant to this clause (ii) which would exceed the Stock Election Cash Pool (as
hereinafter defined)). The foregoing payments shall be referred to herein as the
"Stock Election Merger Consideration." For purposes hereof, "Stock Election Cash
Pool" shall mean an amount of cash equal to the greater of (i) $0 and (ii) the
Aggregate Cash Top-Up Amount minus the aggregate amount of cash paid in the
Merger to the holders of shares of Common Stock that do not make a Stock
Election; and "Aggregate Cash Top-Up Amount" shall mean the lesser of (i) the
product of (x) the Per Share Cash Top-Up Amount and (y) the number of
outstanding shares of Common Stock as of the Effective Time and (ii) an amount
equal to the Maximum Cash Pool. BECAUSE OF THE AIG ELECTION DESCRIBED ABOVE,
THERE CAN BE NO ASSURANCE THAT A HOLDER WHO ELECTS TO RECEIVE AIG COMMON STOCK
WILL IN FACT RECEIVE AIG COMMON STOCK FOR THE FULL AMOUNT OF CONSIDERATION INTO
WHICH HIS COMMON STOCK IS CONVERTED IN THE MERGER.
 
CLOSING; EFFECTIVE TIME
 
     The Closing of the Merger (the "Closing") will take place on the first
business day on which the last to be fulfilled or waived of the conditions to
the Merger set forth in the Merger Agreement to be fulfilled prior to Closing is
satisfied or waived or on such other day as American Bankers and AIG agree in
writing (the "Closing Date"). As soon as practicable following the Closing,
American Bankers and AIG will cause Articles of Merger to be executed,
acknowledged and filed with the Secretary of State of the State of Florida. The
Merger will become effective at the time the Secretary accepts for record the
Articles of Merger or at such later time agreed by the parties and established
under the Articles of Merger (the "Effective Time"). See "-- Conditions of the
Proposed Merger" and "The Merger -- Required Regulatory Filings and Approvals."
 
CANCELLATION OF SHARES
 
     At the Effective Time, all shares of Preferred Stock and Common Stock shall
no longer be outstanding and shall be canceled and retired and shall cease to
exist, and each certificate (a "Certificate") formerly representing any of such
shares (other than Excluded Shares) shall thereafter represent only the right to
the Preferred Stock Merger Consideration or Common Stock Merger Consideration,
as applicable, and the right, if any, to receive cash in lieu of fractional
shares and any distribution or dividend with respect to the AIG Series C
Preferred Stock or AIG Common Stock, each as described below. Each Excluded
Share shall, by virtue of the Merger and without any action on the part of the
holder thereof, cease to be outstanding, shall be canceled and retired without
payment of any consideration therefor and shall cease to exist.
 
FRACTIONAL SHARES
 
     No fractional shares of AIG Common Stock will be issued and any holder of
shares of Common Stock otherwise entitled to receive fractional shares of AIG
Common Stock shall be entitled to receive a cash payment in lieu thereof, in an
amount equal to such fractional share of AIG Common Stock multiplied by the Base
Period Stock Price.
 
EXCHANGE OF CERTIFICATES
 
     Promptly after the Effective Time, AIG shall deposit, or shall cause to be
deposited, with ChaseMellon Shareholders Services, L.L.C. (the "Exchange
Agent"), for the benefit of the holders of shares of Preferred Stock and Common
Stock, certificates representing the shares of AIG Series C Preferred Stock and
AIG Common Stock and, after the Effective Time, if applicable, any cash,
dividends or other distributions with respect to the AIG Series C Preferred
Stock and AIG Common Stock to be issued or paid pursuant to the Merger Agreement
in exchange for shares of Preferred Stock and Common Stock outstanding
immediately prior to the Effective Time upon due surrender of the Certificates
(or affidavits of loss in lieu thereof) (such certificates for shares of AIG
Series C Preferred Stock and AIG Common Stock, together with the amount of
 
                                       40

<PAGE>   49
 
any cash, dividends or other distributions payable with respect thereto, being
hereinafter referred to as the "Exchange Fund"). Promptly after the Effective
Time, the Surviving Corporation shall cause the Exchange Agent to mail to each
holder of record of shares of Preferred Stock and each holder of record of
shares of Common Stock (other than holders of Excluded Shares) who did not
submit a valid Election Form prior to the Election Deadline (i) a letter of
transmittal specifying that delivery shall be effected, and risk of loss and
title to the Certificates shall pass, only upon delivery of the Certificates (or
affidavits of loss in lieu thereof) to the Exchange Agent, and (ii) instructions
for use in effecting the surrender of the Certificates in exchange for (A)
certificates representing shares of AIG Series C Preferred Stock or AIG Common
Stock, as applicable, and (B) if applicable, any cash, unpaid dividends or other
distributions and cash in lieu of fractional shares. Upon surrender of a
Certificate for cancellation to the Exchange Agent together with such letter of
transmittal, duly executed, the holder of such Certificate shall be entitled to
receive in exchange therefor (x) a certificate representing that number of whole
shares of AIG Series C Preferred Stock or AIG Common Stock, as applicable, that
such holder is entitled to receive pursuant to the Merger Agreement, (y) a check
in the amount (after giving effect to any required tax withholdings) of (A) any
cash in lieu of fractional shares plus (B) any cash, including unpaid non-stock
dividends and any other dividends or other distributions, that such holder has
the right to receive pursuant to the provisions of the Merger Agreement, and the
Certificate so surrendered shall forthwith be canceled. No interest will be paid
or accrued on any amount payable upon due surrender of the Certificates. If any
certificate for shares of AIG Series C Preferred Stock or AIG Common Stock, as
applicable, is to be issued in a name other than that in which the Certificate
surrendered in exchange therefor is registered, it shall be a condition of such
exchange that the Person requesting such exchange shall pay any transfer or
other taxes required by reason of the issuance of certificates for shares of AIG
Series C Preferred Stock or AIG Common Stock, as applicable, in a name other
than that of the registered holder of the Certificate surrendered, or shall
establish to the satisfaction of AIG or the Exchange Agent that such tax has
been paid or is not applicable.
 
DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES
 
     All shares of AIG Series C Preferred Stock and AIG Common Stock to be
issued pursuant to the Merger shall be deemed issued and outstanding as of the
Effective Time and whenever a dividend or other distribution is declared by AIG
in respect of the AIG Series C Preferred Stock or AIG Common Stock, as
applicable, the record date for which is at or after the Effective Time, that
declaration shall include dividends or other distributions in respect of all
shares issuable pursuant the Merger Agreement. No dividends or other
distributions in respect of the AIG Series C Preferred Stock or AIG Common
Stock, as applicable, shall be paid to any holder of any unsurrendered
Certificate until such Certificate is surrendered for exchange in accordance
with the Merger Agreement. Subject to the effect of applicable laws, following
surrender of any such Certificate, there shall be issued and/or paid to the
holder of the certificates representing whole shares of AIG Series C Preferred
Stock and AIG Common Stock, as applicable, issued in exchange therefor, without
interest, (A) at the time of such surrender, the dividends or other
distributions with a record date after the Effective Time theretofore payable
with respect to such whole shares of AIG Series C Preferred Stock or AIG Common
Stock, as applicable, and not paid and (B) at the appropriate payment date, the
dividends or other distributions payable with respect to such whole shares of
AIG Series C Preferred Stock or AIG Common Stock, as applicable, with a record
date after the Effective Time but with a payment date subsequent to surrender.
 
TRANSFERS
 
     After the Effective Time, there shall be no transfers on the stock transfer
books of American Bankers of the shares of Preferred Stock or Common Stock that
were outstanding immediately prior to the Effective Time.
 
TERMINATION OF EXCHANGE FUND
 
     Any portion of the Exchange Fund that remains unclaimed by the shareholders
of American Bankers for 180 days after the Effective Time shall be paid to AIG.
Any shareholders of American Bankers shall
 
                                       41

<PAGE>   50
 
thereafter look only to AIG for payment of their shares of AIG Series C
Preferred Stock or AIG Common Stock, as applicable, and any cash, dividends and
other distributions in respect thereof payable and/or issuable pursuant to the
Merger Agreement upon due surrender of their Certificates (or affidavits of loss
in lieu thereof), in each case, without any interest thereon. None of AIG, the
Surviving Corporation, the Exchange Agent or any other Person shall be liable to
any former holder of shares of Preferred Stock or Common Stock for any amount
properly delivered to a public official pursuant to applicable abandoned
property, escheat or similar laws.
 
LOST, STOLEN OR DESTROYED CERTIFICATES
 
     In the event any Certificate shall have been lost, stolen or destroyed,
upon the making of an affidavit of that fact by the Person claiming such
Certificate to be lost, stolen or destroyed and, if required by AIG, the posting
by such Person of a bond in customary amount as indemnity against any claim that
may be made against it with respect to such Certificate, the Exchange Agent will
issue in exchange for such lost, stolen or destroyed Certificate the shares of
AIG Series C Preferred Stock or AIG Common Stock, as applicable, and any cash
payable and any unpaid dividends or other distributions in respect thereof
pursuant to the Merger Agreement upon due surrender of and deliverable in
respect of the shares of Preferred Stock or Common Stock represented by such
Certificate pursuant to the Merger Agreement.
 
ADJUSTMENTS TO PREVENT DILUTION
 
     In the event that American Bankers changes the number of shares of
Preferred Stock or Common Stock or securities convertible or exchangeable into
or exercisable for shares of Preferred Stock or Common Stock, or AIG changes the
number of shares of AIG Common Stock or securities convertible or exchangeable
into or exercisable for shares of AIG Common Stock, issued and outstanding prior
to the Effective Time as a result of a reclassification, stock split (including
a reverse split), stock dividend or distribution, recapitalization, merger,
subdivision or other similar transaction, the Preferred Stock Merger
Consideration or Common Stock Merger Consideration, as applicable, shall be
equitably adjusted.

actions.
 
AGREEMENT NOT TO SOLICIT OTHER OFFERS
 
     American Bankers has agreed that it will not, and it will not permit or
cause any of its Subsidiaries or any of its or its Subsidiaries' directors and
officers to, and it shall direct its and its Subsidiaries' employees, agents and
representatives (including any investment banker, attorney or accountant
retained by it or any of its Subsidiaries) (collectively, its "Representatives")
not to, directly or indirectly, initiate, solicit, encourage or otherwise
facilitate any inquiries or the making of any proposal or offer with respect to
a merger, reorganization, share exchange, consolidation or similar transaction
involving, or any purchase of 15% or more of the assets or any equity securities
of it or any of its Subsidiaries (any such proposal or offer, for the purpose of
the Merger Agreement being referred to as an "Acquisition Proposal"). American
Bankers has further agreed that it will not, and it will not permit or cause any
of its Subsidiaries or any of its or its Subsidiaries'
 
                                       44

<PAGE>   53
 
officers and directors to, and it shall direct its Representatives not to,
directly or indirectly, engage in any negotiations concerning, or provide any
confidential information or data to, or have any discussions with, any Person
relating to an Acquisition Proposal, whether made before or after the date of
the Merger Agreement, or otherwise facilitate any effort or attempt to make or
implement an Acquisition Proposal (including, without limitation, by means of an
amendment to the Rights Agreement); provided, however, that nothing contained in
the Merger Agreement shall prevent American Bankers or the American Bankers
Board from (i) complying with Rule 14e-2 promulgated under the Exchange Act with
regard to an Acquisition Proposal; or (ii) at any time after 120 days from the
date of the Merger Agreement if the Merger shall not by such date have been
approved by the American Bankers Requisite Vote (A) providing information in
response to a request therefor by a Person who has made an unsolicited bona fide
written Acquisition Proposal if the American Bankers Board receives from the
Person so requesting such information an executed confidentiality agreement on
terms substantially equivalent to those contained in the Confidentiality
Agreement (as defined in the Merger Agreement); (B) engaging in any negotiations
or discussions with any Person who has made an unsolicited bona fide written
Acquisition Proposal; or (C) recommending such an Acquisition Proposal to its
shareholders, if and only to the extent that, (i) in each such case referred to
in clause (A), (B) or (C) above, the American Bankers Board determines in good
faith after consultation with outside legal counsel that such action is
necessary in order for the American Bankers directors to comply with their
respective fiduciary duties under applicable law and (ii) in each case referred
to in clause (B) or (C) above, the American Bankers Board determines in good
faith (after consultation with its financial advisor) that such Acquisition
Proposal, if accepted, is reasonably likely to be consummated, taking into
account all legal, financial and regulatory aspects of the proposal and the
Person making the proposal and would, if consummated, result in a more favorable
transaction than the Merger, taking into account the long-term prospects and
interests of it and its shareholders (any such more favorable Acquisition
Proposal being referred to, for the purpose of the Merger Agreement, as a
"Superior Proposal").
 
     American Bankers also has agreed to immediately cease and cause to be
terminated any existing activities, discussions or negotiations with any parties
being conducted prior to execution of the Merger Agreement with respect to any
of the foregoing. American Bankers further agreed that it will take the
necessary steps to promptly inform its officers, directors, Subsidiaries and
Representatives of the foregoing obligations and the obligations in the
Confidentiality Agreement.
 
     American Bankers also agreed to notify AIG immediately if any inquiries,
proposals or offers are received by, any such information is requested from, or
any discussions or negotiations are sought to be initiated or continued with,
any of its Representatives indicating, in connection with such notice, the name
of such Person and the material terms and conditions of any proposals or offers
and thereafter to keep AIG informed, on a current basis, on the status and terms
of any such proposals or offers and the status of any such negotiations or
discussions. American Bankers further agreed to promptly request each Person
that had executed a confidentiality agreement in connection with its
consideration of an Acquisition Proposal to return all confidential information
that had been furnished to such Person by or on behalf of American Bankers or
any of its Subsidiaries.
 
EMPLOYEE BENEFITS
 
     AIG has agreed that from the Effective Time until the first anniversary
thereof, the employees of American Bankers and its Subsidiaries will continue to
be provided with benefits under the existing employee benefit plans of American
Bankers and its Subsidiaries (other than plans involving the issuance or award
of Common Stock or rights to acquire Common Stock) that are no less favorable in
the aggregate than those currently provided by American Bankers and its
Subsidiaries to such employees. Any such employees will receive credit under any
plans of AIG or any of its Subsidiaries for service with American Bankers or its
Subsidiaries or predecessors (to the extent service with such predecessors was
credited under the Compensation and Benefit Plans disclosed in the American
Bankers Disclosure Letter) prior to the Effective Time for the purpose of
determining eligibility and vesting. AIG also has agreed to cause all
pre-existing condition limitations (to the extent such limitations did not apply
to a pre-existing condition under the Compensation and Benefit Plans) and
eligibility waiting periods under group health plans of AIG or any of its
Subsidiaries to
 
                                       45

<PAGE>   54
 
be waived with respect to such participants and their eligible dependants. All
discretionary awards and benefits under any group health plans of AIG or any of
its Subsidiaries shall be subject to the discretion of the persons or committee
administering such plans.
 
TREATMENT OF STOCK OPTIONS
 
     The Merger Agreement provides that at the Effective Time, each outstanding
option to purchase shares of Common Stock under the American Bankers Stock
Plans, whether vested or unvested, shall be deemed to constitute an option to
acquire, on the same terms and conditions, the same number of shares of AIG
Common Stock as the holder of such option would have been entitled to receive
pursuant to the Merger had such holder exercised such option in full immediately
prior to the Effective Time and assuming that the Common Stock Merger
Consideration consisted entirely of shares of AIG Common Stock (rounded down to
the nearest whole number), at a price per share (rounded up to the nearest whole
cent) equal to (y) the aggregate exercise price for the shares of Common Stock
otherwise purchasable pursuant to such option, divided by (z) the number of full
shares of AIG Common Stock deemed purchasable pursuant to such option; provided
that in the case of any option to which Section 422 of the Code applies, the
option price, the number of shares purchasable pursuant to such option, and the
terms and conditions of the exercise of such option shall be subject to such
adjustments as are necessary in order to satisfy the requirements of Section
424(a) of the Code; provided, further, that to the extent that shares of Common
Stock acquired upon exercise of such option would be subject to vesting or other
restrictions under the terms of the relevant American Bankers Stock Plan under
which such option was issued ("American Bankers Restricted Shares"), the number
of shares of AIG Common Stock to be issued upon exercise of an assumed option in
accordance with the foregoing that bears the same ratio to the total shares of
AIG Common Stock deemed purchasable pursuant to such assumed option as the
number of American Bankers Restricted Shares bears to the total number of shares
of Common Stock issuable under such option shall be subject to the same vesting
and other restrictions as would be applicable to the American Bankers Restricted
Shares.
 
     At or prior to the Effective Time, American Bankers shall make all
necessary arrangements with respect to the American Bankers Stock Plans to
permit the assumption by AIG of the unexercised options to purchase shares of
Common Stock in accordance with the above. Effective at the Effective Time, AIG
shall assume each option to purchase shares of Common Stock under the American
Bankers Stock Plans in accordance with the terms of the relevant American
Bankers Stock Plan under which the option was issued and the stock option
agreement by which the option is evidenced.
 
     At or prior to the Effective Time, AIG shall take all corporate action
necessary to reserve for issuance a sufficient number of shares of AIG Common
Stock for delivery upon exercise of options to purchase shares of Common Stock
assumed by AIG and shall, as soon as practicable after the Effective Time, file
a registration statement on Form S-3 or Form S-8 with respect to AIG Common
Stock subject to such options to purchase shares of Common Stock (or shall cause
such options to purchase shares of Common Stock to be deemed to be options
issued pursuant to an AIG Stock Plan for which shares of AIG Common Stock have
previously been registered pursuant to an appropriate registration form) and
shall use its reasonable best efforts to maintain the effectiveness of such
registration statements for so long as such options remain outstanding.
 
TAX MATTERS
 
     The Merger Agreement provides that, subject to the provisions described
under " -- Agreement Not to Solicit Other Offers" and to the possible
restructuring of the Merger described below under "-- Alternative Transaction
Structure", neither AIG nor American Bankers shall take or cause to be taken any
action, before or after the Effective Time, that would disqualify the Merger as
a "reorganization" within the meaning of Section 368(a) of the Code. AIG and
American Bankers also have agreed to use all reasonable efforts to cure any
impediment to the qualification of the Merger as such. See "-- Conditions to the
Proposed Merger" and "The Merger -- Certain Federal Income Tax Consequences of
the Merger".

CERTAIN OTHER COVENANTS AND AGREEMENTS
 
  Information; Filings
 
     American Bankers and AIG have agreed (i) to supply accurate, complete and
updated information in connection with the preparation of this Proxy
Statement/Prospectus and the Registration Statement, (ii) to furnish the other
on request with all information concerning itself, its Subsidiaries, directors,
officers and shareholders and such other matters as may reasonably be necessary
or advisable in connection with this Proxy Statement/Prospectus, the
Registration Statement and any other filing, notice or application made in
connection with the Merger and (iii) to keep each other apprised of the status
of matters relating to the completion of the transactions contemplated by the
Merger Agreement including the provision of copies of communications received
from Governmental Entities and third parties and prompt notice of any change
that is reasonably likely to result in a material adverse effect on the
financial condition, properties, business or results of operations of American
Bankers and its Subsidiaries taken as a whole or AIG and its Subsidiaries taken
as a whole, as the case may be. American Bankers and AIG have agreed to promptly
prepare and file this Proxy Statement/Prospectus with the Commission and AIG has
agreed to promptly prepare and file the Registration Statement with the
Commission. Both parties have agreed to use all reasonable efforts to have the
Registration Statement declared effective as promptly as practicable after
filing and promptly thereafter to mail this Proxy Statement/Prospectus to the
shareholders of American Bankers. AIG also agreed to obtain all required "blue
sky" approvals and to pay all expenses incident thereto. American Bankers and
AIG further agreed to cooperate with one another and to use their respective
best efforts to (i) cause to be done all things necessary, proper or advisable
on its part under the Merger Agreement and applicable laws to consummate and
make effective the Merger and the other transactions contemplated by the Merger
Agreement as soon as practicable, including preparing and filing as promptly as
practicable all documentation to effect all necessary notices, reports and other
filings and (ii) obtain as promptly as practicable all consents, registrations,
approvals, permits and authorizations necessary or advisable to be obtained from
any third party and/or any Governmental Entity in connection with, as a result
of or in order to consummate the Merger or any of the other transactions
contemplated by the Merger Agreement, including, without limitation, upon
request of AIG, all material consents required in connection with the
consummation of the Merger, provided, however, that nothing in the foregoing
requires AIG, in connection with the receipt of any regulatory approval, to (i)
sell or agree to sell or discontinue or limit any assets or businesses or any
interest in any assets or businesses of AIG or American Bankers or any of their
respective affiliates or (ii) agree to any conditions relating to or changes or
restrictions in, the operations of any such assets or businesses which, in
either case, could, in the judgment of the AIG Board, materially and adversely
impact the economic or business benefits to AIG of the transactions contemplated
by the Merger Agreement.
 
  Access
 
     American Bankers has agreed to provide AIG's officers, employees, counsel,
accountants and other authorized representatives with access to its and its
Subsidiaries' management, property, books, contracts and records throughout the
period prior to the Effective Time and during such period to furnish to AIG all
information as it may reasonably request, provided that such access may be
denied to prevent the disclosure of trade secrets of third parties or the breach
of any confidentiality obligations of American Bankers that, in the reasonable
opinion of American Bankers, would otherwise result, if American Bankers has
used all reasonable efforts to obtain the consent of such third parties to such
inspection or disclosure. AIG has agreed to provide American Bankers' officers,
employees, counsel, accountants and other authorized representatives such access
as it reasonably requests (giving due consideration to the size and
capitalization of, and availability of public information concerning, AIG and
the pricing and other terms of the Merger Agreement) to a limited number of
AIG's management personnel and all relevant books and records throughout the
period prior to the Effective Time, provided that such access may be denied in
order to prevent the disclosure of trade secrets of third parties or the breach
of confidentiality obligations of AIG that, in the reasonable judgment of AIG,
would otherwise result. No investigation made by American Bankers or AIG
pursuant to the foregoing shall affect or be deemed to modify any representation
or warranty made by the other party.
 
                                       47

<PAGE>   56
 
  Special Meetings
 
     American Bankers has agreed to take all action necessary to convene the
Preferred Shareholders Special Meeting and the Common Shareholders Special
Meeting as promptly as practicable but in no event later than 45 days after the
Registration Statement is declared effective. Subject to fiduciary obligations
under applicable law, the American Bankers Board shall recommend approval of the
Merger, shall not withdraw or modify such recommendation and shall take all
lawful action to solicit the approval of the Merger. In the event that the
American Bankers Board withdraws or modifies its recommendation, American
Bankers has agreed that the Preferred Shareholders Special Meeting and the
Common Shareholders Special Meeting shall nevertheless be convened, votes with
respect to the Merger shall be taken and the reasons for such withdrawal or
modification shall be communicated to the shareholders of American Bankers in
accordance with the FBCA.
 
  Directors and Officers of the Surviving Corporation
 
     The Merger Agreement provides that, immediately following the Effective
Time, the directors of American Bankers who are willing to serve as directors of
the Surviving Corporation shall be appointed as directors of the Surviving
Corporation and that AIG shall designate and appoint two additional directors of
the Surviving Corporation. The Merger Agreement further provides that the
officers of American Bankers at the Effective Time shall be the officers of the
Surviving Corporation.
 
  Indemnification of Directors and Officers; Directors and Officers' Insurance
 
     AIG has agreed to indemnify each present and former director and officer of
American Bankers from liability arising out of matters existing or occurring at
or prior to the Effective Time to the fullest extent that American Bankers would
have been permitted to indemnify such parties under Florida law and the American
Bankers Articles and Bylaws. AIG also has agreed that the Surviving Corporation
will maintain American Bankers' existing officers' and directors' liability
insurance or purchase substantially comparable insurance for up to six years
following the Effective Time, subject to certain maximum required premium
amounts. See "The Merger -- Interests of Certain Persons in the Merger".
 
  Dividends
 
     The parties have agreed to coordinate the declaration, setting of record
dates and payment dates of dividends on Preferred Stock and Common Stock to
ensure that (i) holders thereof do not receive dividends in respect of any
calendar quarter on both Preferred Stock and AIG Series C Preferred Stock or on
both Common Stock and AIG Common Stock, as applicable, or (ii) holders thereof
do not fail to receive dividends in respect of any calendar quarter on either
Preferred Stock or AIG Series C Preferred Stock or on either Common Stock or AIG
Common Stock, as applicable.
 
  Affiliates Letters
 
     American Bankers has agreed to deliver to AIG prior to the Shareholders
Meetings, a list of names and addresses of those persons who will be deemed to
be "affiliates" (as such term is defined under the Securities Act) of American
Bankers, in the opinion of American Bankers, as of the time of the Preferred
Shareholders Special Meeting and the Common Shareholders Special Meeting, which
list shall be updated with the names of persons who may be so deemed and are
subsequently so identified as affiliates. American Bankers has further agreed to
use its reasonable best efforts to deliver or cause to be delivered to AIG prior
to the Preferred Shareholders Special Meeting and the Common Shareholders
Special Meeting, an Affiliates Letter from each affiliate identified in the
foregoing list. AIG shall not be obligated to maintain the effectiveness of the
Registration Statement or any other registration statement for the purposes of
resale by such affiliates of AIG Common Stock or AIG Series C Preferred Stock.
See "The Merger -- Resale of AIG Common Stock and AIG Series C Preferred Stock".

best efforts to cause the Common Stock and the Preferred Stock to be delisted

TERMINATION
 
     The Merger Agreement may be terminated: (i) at any time prior to the
Effective Time, whether before or after approval of the Merger Agreement by
holders of Preferred Stock or Common Stock and by the sole shareholder of
Surviving Corporation, by mutual written consent of American Bankers and AIG;
(ii) by American Bankers or AIG, any time before or after the Merger Agreement
is approved by holders of Preferred Stock or Common Stock, if the Merger shall
not have been consummated by September 30, 1998 (provided that the terminating
party is not otherwise in material breach of its obligations under the Merger
Agreement in any manner that shall have proximately contributed to the
occurrence of the failure of the Merger to be consummated); (iii) by AIG if the
approval of the holders of a majority of the outstanding shares of Common Stock
shall not have been obtained at a meeting duly convened therefor or any
adjournment or postponement thereof; (iv) by American Bankers, any time after
180 days following the date of the Merger Agreement, if the approval of the
holders of a majority of the outstanding shares of Common Stock shall not have
been obtained at a meeting duly convened therefor or any adjournment or
postponement thereof (provided that, prior to or at the time of such meeting,
any person shall have made an Acquisition Proposal to American Bankers or any of
its Subsidiaries or any of its shareholders or shall have publicly announced an
intention to make such an Acquisition Proposal); (v) by American Bankers or AIG
if any Order permanently restraining, enjoining or otherwise prohibiting
consummation of the Merger shall become final and non-appealable; (vi) by
American Bankers, any time before the approval of the holders of a majority of
the outstanding shares of Preferred Stock and the holders of a majority of the
outstanding shares of Common Stock, each voting as a separate class, shall have
been obtained, if the American Bankers Board authorizes it to enter into an
agreement with respect to a Superior Proposal (subject to (w) there being no
material breach by American Bankers of the provisions of the Merger Agreement,
(x) American Bankers giving written notice of such Superior Proposal to AIG, (y)
AIG failing to make, prior to the later of five business days after receipt of
American Bankers' written notice of its intention to enter into a binding
agreement for a Superior Proposal and June 19, 1998, an offer that the American
Bankers' Board determines, in good faith after consultation with its financial
advisors, is at least as favorable as the Superior Proposal, taking into account
the long term prospects and interests of American Bankers and its shareholders
and (z) American Bankers paying to AIG prior to termination of the Merger
Agreement the fees described under "-- Expenses and Termination Fees"; (vii) by
American Bankers or AIG at any time prior to the Effective Time in the event of
a material breach by the other party of any representation, warranty, covenant
or agreement which is not curable or not cured as provided in the Merger
Agreement; or (viii) by AIG at any time prior to the Effective Time, whether
before or after approval of the holders of a majority of the outstanding shares
of Preferred Stock and the holders of a majority of the outstanding shares of
Common Stock, each voting as a separate class, if American Bankers enters into a
binding agreement for a Superior Proposal or if the American Bankers Board
withdraws or modifies its approval or recommendation of the Merger Agreement or,
after the mailing of this Proxy Statement/Prospectus, fails to reconfirm its
recommendation within ten business days after a written request by AIG to do so.
 
EXPENSES AND TERMINATION FEES
 
     The Merger Agreement provides that the Surviving Corporation shall pay all
expenses arising in connection with the exchange of Preferred Stock for AIG
Series C Preferred Stock and the exchange of Common Stock for the Common Stock
Merger Consideration. Except as described below, whether or not the Merger is
consummated, all costs and expenses incurred in connection with the Merger
Agreement, the Merger and the other transactions contemplated by the Merger
Agreement shall be paid by the party incurring such expenses, except that the
filing fee for the Registration Statement and expenses incurred in connection
with the printing and mailing of this Proxy Statement/Prospectus and the
Registration Statement shall be shared equally by AIG and American Bankers.
 
     The Merger Agreement provides that if it is terminated by American Bankers
in the manner described in clause (iv) or clause (vi) under "-- Termination" or
by AIG in the manner described in clause (iii) under "-- Termination" (and prior
to, or at the time of the meeting referred to therein any Person shall have made
an Acquisition Proposal to American Bankers or any of its Subsidiaries or any of
its shareholders shall have
 
                                       50

<PAGE>   59
 
publicly announced an intention to make such an Acquisition Proposal) or in the
manner described in clause (viii) under "-- Termination", then American Bankers
shall not later than two days after the date of such termination or date of
entrance into an agreement concerning a transaction that constitutes an
Acquisition Proposal or such earlier time as required by the Merger Agreement,
pay AIG a termination fee of $66 million.
 
AMENDMENT AND WAIVER
 
     Subject to the provisions of applicable law, any provision of the Merger
Agreement may be amended or modified at any time prior to the Effective Time by
means of a written agreement executed and delivered by duly authorized officers
of the respective parties. The conditions to each of the parties' obligations to
consummate the Merger are for the sole benefit of such party and may be waived
by such party in whole or in part to the extent permitted by applicable law.
 
ALTERNATIVE TRANSACTION STRUCTURE
 
     The Merger Agreement provides that if the vote of the holders of a majority
of the outstanding shares of Preferred Stock is not obtained at the Preferred
Shareholders Special Meeting or AIG reasonably determines that such vote is not
likely to be obtained, AIG shall, subject to the vote of the holders of a
majority of the outstanding shares of Common Stock and the other terms and
conditions of the Merger Agreement (other than the covenant relating to actions
that would disqualify the Merger as a "reorganization" under the Code and the
provision of opinions of counsel as to the treatment of the Merger as a
"reorganization" under the Code), merge AIGF with and into American Bankers such
that the separate corporate existence of AIGF shall cease and American Bankers
shall continue as the Surviving Corporation. American Bankers agrees to take all
actions reasonably requested by AIG to effect the above alternative transaction
structure, including, without limitation, promptly entering into an amendment to
the Merger Agreement to provide, inter alia, that the Preferred Stock shall
remain outstanding after the Merger pursuant to its current terms and conditions
except that it shall be convertible into AIG Common Stock.
 
     Under the alternative transaction structure described above, the Merger
would not qualify as a "reorganization" under the Code. The exchange of Common
Stock for Common Stock Merger Consideration pursuant to the Merger therefore
would be fully taxable for federal income tax purposes. A holder of Common Stock
would generally recognize gain or loss equal to the difference between (i) the
amount of cash and, in the case of holders receiving AIG Common Stock, the value
(determined as of the Effective Time) of AIG Common Stock, that the holder
receives as a result of the Merger and (ii) the holder's adjusted tax basis in
the shares of Common Stock that the holder exchanges in the Merger. Such gain or
loss would be calculated separately for each block of Common Stock exchanged by
the holder. Such gain or loss would generally be capital gain or loss if a block
of Common Stock is held as a capital asset and would generally be long-term
capital gain or loss to the extent that, at the Effective Time, the holder has a
holding period for federal income tax purposes in such block of Common Stock of
more than one year.
 
     Because under the above alternative transaction structure the Preferred
Stock would remain outstanding following the Merger, the Merger would have no
immediate federal income tax consequences to holders of Preferred Stock. Prior
to the Merger, a conversion of Preferred Stock into Common Stock pursuant to the
terms of the Preferred Stock would not result in the recognition of gain or loss
for federal income tax purposes. If the Merger is not restructured, after the
Merger a conversion of AIG Series C Preferred Stock into AIG Common Stock would
also be tax free. If, however, the Merger is restructured, a future conversion
of Preferred Stock into AIG Common Stock would be a taxable transaction for
federal income tax purposes.
 
     The foregoing discussion is based upon the Code, applicable Treasury
Regulations thereunder and administrative rulings and judicial authority as of
the date hereof. All of the foregoing are subject to change, possibly with
retroactive effect. In addition, the foregoing discussion does not address the
tax consequences that may be relevant to a particular shareholder subject to
special treatment under certain federal income tax laws. THUS, HOLDERS OF COMMON
STOCK AND HOLDERS OF PREFERRED STOCK ARE URGED TO CONSULT THEIR OWN TAX ADVISORS
AS TO THE SPECIFIC TAX CONSEQUENCES THAT WOULD RESULT TO THEM IF THE MERGER WERE
TO TAKE PLACE PURSUANT TO THE ALTERNATIVE TRANSACTION STRUCTURE DESCRIBED ABOVE.

                      RELATED AGREEMENTS AND TRANSACTIONS
 
STOCK OPTION AGREEMENT
 
     The following description of certain terms of the Stock Option Agreement is
only a summary and does not purport to be complete. This discussion is qualified
in its entirety by reference to the Stock Option Agreement, a copy of which is
attached hereto as Appendix II.
 
  The Option
 
     In order to induce AIG to enter into the Merger Agreement, American Bankers
entered into the Stock Option Agreement. Pursuant to the Stock Option Agreement,
AIG has the option (the "Option"), under the circumstances described below, to
acquire up to 8,265,626 shares of authorized but unissued Common Stock (the
"Option Shares") (or approximately 19.9% of the outstanding Common Stock as of
November 3, 1997 prior to giving effect to the exercise of such Option),
including the associated rights under the Rights Agreement, at a price of $47.00
per share (the "Option Price"). The Stock Option Agreement could have the effect
of making an acquisition of American Bankers by a third party more costly
because of the need to acquire in any such transaction the Option Shares issued
under the Stock Option Agreement, and could also jeopardize the ability of a
third party to acquire American Bankers in a transaction accounted for as a
pooling of interests.
 
     The Option may be exercised by AIG, in whole or in part, at any time or
from time to time on the occurrence of one or more of the Triggering Conditions
described in the following paragraph. AIG may exercise the Option by either (a)
paying the Option Price in cash and receiving the Option Shares (which exercise
requires the satisfaction of certain additional conditions) or (b) electing, in
lieu of the payment of the Option Price and the receipt of the Option Shares, to
receive a cash payment (the "Cash Payment") from American Bankers. Such Cash
Payment shall be in the amount of the excess of (i) the higher of (x) the
highest price per share of Common Stock paid or proposed to be paid pursuant to
one of the Triggering Conditions and (y) the closing price of shares of Common
Stock on the NYSE Composite Tape on the last trading day immediately prior to
receipt by American Bankers of AIG's notice of its intention to receive the Cash
Payment, over (ii) the Option Price, multiplied by all or such portion of the
Option Shares as AIG specifies in such notice.
 
  Triggering Conditions
 
     The Option may be exercised on satisfaction of certain conditions,
including the occurrence of at least one of the following "Triggering
Conditions": (i) any person (as defined in Sections 3(a)(9) and 13(d)(3) of the
Exchange Act) (other than AIG or any of its subsidiaries) shall have commenced a
tender offer (as defined in Rule 14d-2 of the Exchange Act) or filed a
registration statement under the Securities Act with respect to an exchange
offer to purchase any shares of Common Stock such that, upon consummation of
such offer, such person or a "group" (as such term is defined under the Exchange
Act) of which such person is a member, shall have acquired beneficial ownership
(as such term is defined in Rule 13d-3 of the Exchange Act) or the right to
acquire beneficial ownership of 15% or more of the then outstanding Common
Stock; (ii) any person (other than AIG or its Subsidiaries) shall have publicly
announced or delivered to American Bankers a proposal, or disclosed publicly or
to American Bankers an intention to make a proposal, to purchase 15% or more of
the assets or any equity securities of, or to engage in a merger,
reorganization, tender offer, share exchange, consolidation or similar
transaction involving American Bankers or any of its subsidiaries (an
"Acquisition Transaction"); (iii) American Bankers or any of its subsidiaries
shall have authorized, recommended, proposed or publicly announced an intention
to authorize, recommend or propose, or entered into, an agreement, including
without limitation, an agreement in principle, with any person (other than AIG
or any of its Subsidiaries) to effect or provide for an Acquisition Transaction;
(iv) any person shall have solicited proxies or consents or announced a bona
fide intention to solicit proxies or consents from American Bankers'
shareholders (x) relating to directors, (y) in opposition to the Merger, the
Merger Agreement or any related transactions or (z) relating to an Acquisition
Transaction (other than solicitations of shareholders seeking approval of the
Merger, the Merger Agreement or any related transactions); or (v) any person
(other than AIG or any of its Subsidiaries) shall have acquired beneficial
ownership or the right to acquire beneficial ownership of, or any "group" shall
have been formed which beneficially owns or has the right to acquire
 
                                       52

<PAGE>   61
 
beneficial ownership of, shares of Common Stock (other than trust account
shares) aggregating 15% or more of the then outstanding Common Stock.
 
  Repurchase Right and Sale Rights
 
     If AIG exercises the Option but neither AIG nor any other person has
acquired more than fifty percent (excluding the Option Shares) of the shares of
outstanding Common Stock prior to the first anniversary of the termination of
the Merger Agreement, American Bankers shall have the right, during the 30-day
period beginning on such anniversary, to purchase from AIG all (but not less
than all) of the Option Shares previously purchased by AIG at a purchase price
equal to the greater of (i) the Option Price or (ii) the average of the last
sales prices for Common Stock on the five trading days ending five days prior to
the date American Bankers gives notice of its intention to exercise such right.
In addition, if AIG exercises the Option, at any time prior to the first
anniversary of the termination of the Merger Agreement, AIG shall have the right
to sell to American Bankers all (but not less than all) of the Option Shares
previously purchased by AIG at a price equal to the greater of (i) the Option
Price or (ii) the average of the last sales prices for Common Stock on the five
trading days ending five days prior to the date AIG gives notice of its
intention to exercise such right.
 
     The Stock Option Agreement further provides that if AIG desires to sell any
of the Option Shares within three years after the purchase of such shares and
such sale requires the registration of such shares under the Securities Act,
American Bankers shall be required to cooperate with AIG in registering such
shares including preparing and filing a registration statement under the
Securities Act for the purpose of permitting such sale of shares by AIG.
American Bankers shall not be required to have declared effective more that two
such registration statements.
 
  Profit Limitation
 
     Notwithstanding any other provisions of the Stock Option Agreement, (i) in
no event shall AIG's Total Profit (as defined below) exceed $66 million and (ii)
the Option may not be exercised for a number of Option Shares that would result
in a Notional Total Profit (as defined below) of more than $66 million.
 
     "Total Profit" means the aggregate amount (before taxes) of (i) any
termination fees received by AIG pursuant to the Merger Agreement, (ii) any Cash
Payments received by AIG pursuant to the Stock Option Agreement, (iii) any
amount received by AIG for the repurchase of the Option Shares by American
Bankers less the purchase price paid by AIG for such shares and (iv) any net
cash amounts received by AIG pursuant to the sale of the Option Shares to an
unaffiliated party less the purchase price paid by AIG for such shares.
"Notional Total Profit" means, with respect to such number of Option Shares as
to which AIG proposes to exercise the Option, the Total Profit determined as of
the date on which AIG gives notice of its intention to exercise the Option,
assuming that the Option was exercised on such date for the designated number of
Option Shares and assuming that such shares, together with all other Option
Shares held by AIG and its affiliates as of such date, were sold for cash at the
closing market price for the Common Stock as of the close of business on the
preceding trading day (less customary brokerage commissions).
 
  Termination
 
     The right to exercise the Option shall terminate upon the earlier of (i)
the Effective Time of the Merger, (ii) 90 days after the termination of the
Merger Agreement (the "Option Termination Date"); or (iii) 18 months after the
date of the Stock Option Agreement. If the Option cannot be exercised or the
Option Shares cannot be delivered to AIG upon such exercise because the
conditions set out in the Stock Option Agreement (excluding the condition that
one or more of the Triggering Conditions shall have occurred) have not been
satisfied, the Option Termination Date shall be extended until thirty days after
such impediment to exercise or delivery has been removed.
 
  Exercise of Option
 
     Subsequent to the announcement of Cendant's proposal, AIG on January 27,
1998 sent a notice to American Bankers exercising its option to purchase the
8,265,626 shares of Common Stock issuable under the Stock Option Agreement. The
consummation of such purchase is subject to applicable regulatory approvals.

Issuance of the shares subject to the Stock Option Agreement may delay or make
more difficult an acquisition of American Bankers by a person other than AIG.
 
VOTING AGREEMENT
 
     The following description of certain terms of the Voting Agreement is only
a summary and does not purport to be complete. This discussion is qualified in
its entirety by reference to the complete text of the Voting Agreement, a copy
of which is attached hereto as Appendix III.
 
  Voting and Proxies
 
     In order to induce AIG to enter into the Merger Agreement, each of Messrs.
Landon and Gaston (the "Shareholders") entered into the Voting Agreement.
Pursuant to and during the term of the Voting Agreement, each of the
Shareholders has agreed to vote all of the shares of Common Stock beneficially
owned by him (the "Shares") and all of the shares of Common Stock subsequently
acquired by him (the "New Shares"), and to cause any holder of record of such
Shares and New Shares to vote, (i) in favor of adoption and approval of the
Merger Agreement and the Merger at every meeting of the shareholders of American
Bankers at which such matters are considered and at every adjournment thereof
and (ii) against any action or proposal that would compete with or could serve
to materially interfere with, delay, discourage, adversely affect or inhibit the
timely consummation of the Merger. Each Shareholder has agreed to deliver to AIG
upon request a proxy which shall be coupled with an interest and irrevocable to
the extent permitted under Florida law, with the total number of his Shares
correctly indicated thereon (and to do the same in respect of New Shares). Each
Shareholder also has agreed to take, or cause to be taken, all actions, and to
do, or cause to be done, all things necessary or advisable in order to
consummate and make effective the transactions contemplated by the Voting
Agreement.
 
  Prohibited Actions
 
     Each Shareholder has agreed that he will not, and will not permit any
entity under his control to, (i) solicit proxies or become a "participant" in a
"solicitation" (as such terms are defined in Regulation 14A under the Exchange
Act) in opposition to or competition with the consummation of the Merger or
otherwise encourage or assist any party in taking or planning any action which
would compete with or could serve to materially interfere with, delay,
discourage, adversely affect or inhibit the timely consummation of the Merger in
accordance with the Merger Agreement, (ii) directly or indirectly encourage,
initiate or cooperate in a shareholders' vote or action by consent of American
Bankers shareholders in opposition to or in competition with the consummation of
the Merger, or (iii) become a member of a "group" (as such term used in Section
13(d) of the Exchange Act) with respect to any voting securities of American
Bankers for the purpose of opposing or competing with the consummation of the
Merger. However, the Voting Agreement does not restrict any director of American
Bankers from taking any action such director reasonably believes is necessary to
satisfy such director's fiduciary duty to shareholders of American Bankers.
 
     During the term of the Voting Agreement, each of the Shareholders has
agreed (i) not to, and not to permit any entity under his control to, deposit
any of the Shares into a voting trust or subject the Shares to any other
arrangement with respect to voting and (ii) not to voluntarily transfer, sell,
offer, pledge or otherwise dispose of or encumber any of the Shares or New
Shares, except that disposals of Shares or New Shares by each Shareholder for
proceeds not exceeding certain specified dollar amounts are permitted.
 
  Other Provisions
 
     The Voting Agreement also contains provisions relating to, among other
things, representations and warranties by the Shareholders, the surrender of
stock certificates representing Shares and New Shares for the purpose of placing
appropriate legends thereon, and specific performance of the Voting Agreement.
The Voting Agreement terminates upon the earliest to occur of (i) the Effective
Time of the Merger, (ii) the termination of the Merger Agreement or (iii)
September 30, 1998.

AMENDMENT TO AMERICAN BANKERS' RIGHTS AGREEMENT
 
     On December 19, 1997, American Bankers and ChaseMellon Shareholder
Services, L.L.C., a New York banking corporation (as successor to Manufacturers
Hanover Trust Company), entered into Amendment Number One ("Amendment Number
One") to the Rights Agreement dated as of November 24, 1988, as Amended and
Restated as of November 14, 1990 (the "Rights Agreement"). Amendment Number One
provides that the execution, delivery or consummation of the transactions
contemplated by the Merger Agreement, the Stock Option Agreement and the Voting
Agreement will not cause the rights contemplated by the Rights Agreement to
become exercisable.
 
EMPLOYMENT AGREEMENTS
 
     American Bankers has entered into employment agreements with Mr. Gerald
Gaston (the "Gaston Employment Agreement"), and Mr. Floyd Denison (the "Denison
Employment Agreement") (collectively, the "Employment Agreements"). Each of Mr.
Gaston and Mr. Denison are referred to herein as "executives". The Employment
Agreements become effective commencing on the Effective Time and continue for
five years. Pursuant to the terms of the Gaston Employment Agreement and the
Denison Employment Agreement, respectively, Mr. Gaston will serve as President
and Chief Executive Officer of American Bankers, and Mr. Denison will serve as
American Bankers's Executive Vice President -- Finance. During the term of the
Employment Agreements, each executive will be allowed to participate in all
general employee benefit plans and programs (including incentive and other
executive compensation plans from time to time in effect for senior executives
of American Bankers).
 
     Pursuant to the Employment Agreements, in the event of a termination of
employment by American Bankers other than for Cause (as defined in the
Employment Agreements), or a termination of employment by the executive for Good
Reason (as defined in the Employment Agreements), the executive will be entitled
to receive an amount equal to the maximum amount that would not constitute a
"parachute payment" (as defined in Section 280G of the Code, or any successor
provision), as determined by American Bankers's independent auditors as of the
executive's date of termination.
 
     The Employment Agreements provide that (i) in the event of termination of
employment due to the death of the executive prior to the expiration of the
term, American Bankers will pay to such executive's designated beneficiary or
estate an amount equal to one hundred and fifty (150%) percent of executive's
base annual salary in effect on the date of termination, and (ii) in the event
of termination of employment due to the disability (as defined in the Employment
Agreements) of the executive prior to the expiration of the term, American
Bankers will pay to such executive's designated beneficiary or estate an amount
equal to fifty (50%) percent of executive's base annual salary in effect on the
date of termination.
 
     The Employment Agreements provide that during the term of executive's
employment and for the three-year period thereafter, each executive agrees that
he will not, directly or indirectly, own, manage, operate, control, be employed
by, advise or in any manner participate or engage in any business competitive
with any business in which American Bankers or any of its affiliates is engaged
at the time of executive's termination or thereafter. In addition, the
Employment Agreements provide that during the term of executive's employment and
for the two-year period thereafter, each executive agrees that he will not,
directly or indirectly, on behalf of executive or any other person, (i) solicit
for employment by other than American Bankers any person who is at such time
employed by American Bankers or its affiliates (or who was so employed at any
time during the one-year period prior to executive's date of termination), or
(ii) solicit or accept business from (x) any customer of American Bankers or its
affiliates, if such customer had dealings with American Bankers or its
affiliates at any time during the one-year period immediately preceding
executive's date of termination, or (y) any customer prospect of American
Bankers or its affiliates, if such customer prospect had been the subject of
solicitations by American Bankers or its affiliates at any time during the
one-year period immediately preceding executive's date of termination.
 
     On and after the Effective Time, the Employment Agreements will supersede
the severance agreements currently in effect between American Bankers and the
executives.

AMENDMENTS TO SEVERANCE AGREEMENTS
 
     American Bankers is currently a party to severance agreements (the
"Severance Agreements") with Messrs. Michael Ray, Stephen T. Williams, Leonardo
F. Garcia, Jason J. Israel, Thomas Hayes, Arthur Heggen, R. Kirk Landon, Jay
Fuchs, Eugene Becker, Sanford Neubarth, and Philip Bruce Camacho (each, an
"Officer", and collectively "Officers"). Pursuant to the Merger Agreement,
American Bankers has agreed to use its best efforts to cause the Officers to
agree to amendments to the Severance Agreements.
 
     Severance Agreements that were entered into prior to 1989 (the "Prior
Severance Agreements") provide that an Officer is entitled to receive payment of
an amount (the "Designated Amount") equal to twice the Officer's Current Annual
Salary (as defined in the Severance Agreement) in the event that American
Bankers is Merged or Sold (as defined in the Severance Agreement), regardless of
whether the Officer had terminated his employment. Under the terms of the Prior
Severance Agreements, American Bankers would be treated as having been Merged or
Sold as a result of the consummation of the Merger, and the Officers would be
entitled to payment of an amount equal to the Designated Amount. The proposed
amendment to the Prior Severance Agreements would provide (i) that no payment
will be due to an Officer solely as a result of American Bankers being Merged or
Sold, and (ii) that upon the termination of the employment of the Officer for
Good Reason (as defined in the proposed amendment) or under certain other
circumstances during the 24-month period following the date on which American
Bankers is Merged or Sold (as defined in the Severance Agreement), the Officer
would be entitled to receive payment of an amount equal to the Designated
Amount.
 
     Severance Agreements that were entered into after 1988 (the "Recent
Severance Agreements") provide that if, within 24 months following a Change of
Control (as defined in the Recent Severance Agreements) of American Bankers, an
Officer in good faith determines that there has been a significant adverse
change in circumstances affecting such Officer's position or status within
American Bankers, such Officer may terminate his employment and be entitled to
receive payment of an amount (the "Maximum Amount") equal to the maximum amount
that will not constitute a "parachute payment" as defined in Section 280G of the
Code, as amended (or any successor provision or, if no such provision exists, as
defined in such provision immediately prior to its repeal) and as calculated by
American Bankers's independent auditors. The Recent Severance Agreements also
provide that within fifteen (15) business days following the occurrence of a
Change in Control (as defined in the Recent Severance Agreements) of American
Bankers, American Bankers is required to deposit with an escrow agent an amount
(the "Escrow Deposit") equal to the Maximum Amount calculated as of the date of
such Change in Control. The proposed amendment to the Recent Severance
Agreements would provide (i) that American Bankers is not required to make any
Escrow Deposit in respect of a Change in Control (as defined in the Recent
Severance Agreements) resulting from the consummation of the transactions
contemplated by the Merger Agreement, (ii) that the provision permitting the
Officer to resign in the event of a significant adverse change in circumstances
during the 24-month period following a Change in Control (as defined in the
Recent Severance Agreements) be modified to provide that the Officer shall be
permitted to terminate employment during such 24-month period and receive
payment of an amount equal to the Maximum Amount only if such termination is for
Good Reason (as defined in the proposed amendment).

                     INFORMATION REGARDING AMERICAN BANKERS
 
     American Bankers is a specialty insurer providing primarily credit-related
insurance products in the U.S. and Canada as well as in Latin America, the
Caribbean and the United Kingdom. The majority of American Bankers' gross
collected premiums are derived from credit-related insurance products sold
through financial institutions and other entities which provide consumer
financing as a regular part of their businesses.
 
     American Bankers' credit-related insurance products consist primarily of
credit unemployment, accidental death and dismemberment ("AD&D"), disability,
property, and life insurance issued in connection with the financing of consumer
purchases. Credit-related insurance products generally offer a consumer a
convenient option to insure a credit card or loan balance so that the amount of
coverage purchased equals the amount of outstanding debt. Coverage is generally
available to all consumers with few of the underwriting conditions that apply to
ordinary term insurance, such as medical examinations and medical history
reports. American Bankers' life and AD&D insurance products generally provide
payment in full of the outstanding debt balance in the event of the insured's
death. The unemployment and disability products satisfy the minimum monthly loan
payment for a specified duration in the event of unemployment or disability.
American Bankers' property insurance products pay the loan balance or the cost
of repairing or replacing the insured's merchandise in the event of a loss due
to a covered event. American Bankers avoids lines of insurance characterized by
long loss payout periods, such as workers' compensation and most general
liability coverages.
 
     American Bankers markets its products on a wholesale basis through a
network of clients that consist primarily of major financial institutions,
retailers and other entities which provide consumer financing as a regular part
of their businesses. American Bankers enters into contracts, typically with
terms of three to five years, with its corporate clients pursuant to which such
clients market American Bankers' insurance products to their customers. In
return, these clients receive expense reimbursements or commissions and are thus
able to recover costs associated with the marketing of the insurance and
generate incremental revenues. American Bankers' clients typically share in the
profitability of business written through them.
 
     American Bankers also writes non credit-related insurance in markets where
it believes it has less competition from other insurers. For example, American
Bankers' extended service contracts products pay the cost of repairing or
replacing the insured's merchandise in the event of damages due to a covered
event. In addition, American Bankers acts as an administrator for the National
Flood Insurance Program, for which it earns a fee for collecting premiums and
processing claims. American Bankers does not assume any underwriting risk with
respect to this program.
 
     American Bankers' business strategy is to continue developing distribution
channels which provide access to large numbers of potential insureds in markets
not traditionally served by other insurance companies. In addition, American
Bankers emphasizes long-term relationships and the development of insurance
programs designed to meet individual client needs. An essential part of American
Bankers' strategy is to invest in technology which enables American Bankers to
accommodate a large group of clients and their customers while simultaneously
offering customized insurance programs.

                        DESCRIPTION OF AIG CAPITAL STOCK
 
     The following description does not purport to be complete and is qualified
in its entirety by reference to the AIG Certificate, the AIG Bylaws and the
Delaware General Corporation Law ("DGCL").
 
GENERAL
 
     The authorized capital stock of AIG consists of 1,000,000,000 shares of
Common Stock and 6,000,000 shares of preferred stock, par value $5.00 per share
("AIG Preferred Stock"). As of December 31, 1997, there were 699,518,281 shares
of AIG Common Stock outstanding, and no shares of AIG Preferred Stock
outstanding.
 
AIG COMMON STOCK
 
     All of the outstanding shares of AIG Common Stock are fully paid and
nonassessable. Subject to the prior rights of the holders of AIG Preferred Stock
that may be issued and outstanding, the holders of AIG Common Stock are entitled
to receive dividends as and when declared by the AIG Board out of funds legally
available therefor, and, in the event of the dissolution of AIG, to share
ratably in all assets remaining after payment of liabilities and satisfaction of
the liquidation preferences, if any, of then outstanding shares of AIG Preferred
Stock, as provided in the AIG Certificate. Each holder of AIG Common Stock is
entitled to one vote for each share held of record on all matters presented to a
vote at a shareholders meeting, including the election of directors. Holders of
AIG Common Stock have no cumulative voting rights or preemptive rights to
purchase or subscribe for any stock or other securities and there are no
conversion rights or redemption or sinking fund provisions with respect to such
stock. Additional authorized shares of AIG Common Stock may be issued without
shareholder approval.
 
AIG PREFERRED STOCK
 
     The authorized but unissued shares of AIG Preferred Stock are available for
issuance from time to time at the discretion of the AIG Board without
shareholder approval (except that the holders of the shares of AIG Series C
Preferred Stock shall have the right to vote on any issuance of AIG Preferred
Stock to the extent that such issuance would cause the total number of
outstanding shares of AIG Preferred Stock to exceed 3,500,000 and in the
circumstances described below under "-- Voting Rights"). The AIG Board has the
authority to determine for each series of AIG Preferred Stock it establishes the
number, designation, preferences, limitations, and relative rights of the shares
of such series, subject to applicable law and the provisions of any outstanding
series of AIG Preferred Stock (including the AIG Series C Preferred Stock). The
terms of any series of AIG Preferred Stock, including without limitation the
dividend rate, redemption price, liquidation rights, sinking fund provisions,
conversion rights and voting rights, and any corresponding effect on other
shareholders, will be dependent largely on factors existing at the time of
issuance. Such terms and effects could include restrictions on dividends on the
AIG Common Stock if dividends on the AIG Preferred Stock are in arrears,
dilution of the voting power of other shareholders to the extent a series of the
AIG Preferred Stock has voting rights, and reduction of amounts available for
liquidation as a result of any liquidation preference granted to any series of
AIG Preferred Stock.
 
AIG SERIES C PREFERRED STOCK
 
     The description set forth below of the AIG Series C Preferred Stock is
qualified in its entirety by reference to the Certificate of Designation for the
AIG Series C Preferred Stock, a copy of which is attached as Appendix V to this
Proxy Statement/Prospectus. A copy of the Certificate of Designation for the
Preferred Stock is attached as Appendix VI to this Proxy Statement/Prospectus.
 
     The AIG Series C Preferred Stock has been authorized as a new series of AIG
Preferred Stock, consisting of 2,300,000 shares.
 
                                       58

<PAGE>   67
 
  Dividends
 
     Holders of shares of AIG Series C Preferred Stock will be entitled to
receive, when, as and if declared by the AIG Board out of funds legally
available therefor, cash dividends at an annual rate of $3.125 per share,
payable quarterly in arrears on February 1, May 1, August 1 and November 1 of
each year, commencing on the date designated for payment following the quarterly
period in which the Merger closes (such dividend to accrue from the first day of
such quarterly period), except that if any such date is a Saturday, Sunday or
legal holiday then such dividend will be payable on the next day that is not a
Saturday, Sunday or legal holiday. Dividends will accrue and be cumulative from
such date of initial issuance and will be payable to holders of record as they
appear on the stock transfer books on such record dates as are fixed by the AIG
Board (provided that no record date shall be later than (a) the sixth business
day prior to the date fixed for any redemption of the AIG Series C Preferred
Stock or, (b) in the case of the dividend payment date occurring on August 1,
2000, the tenth business day prior to such date).
 
     The AIG Series C Preferred Stock will have priority as to dividends over
the AIG Common Stock and any other series or class of AIG's stock hereafter
authorized over which the AIG Series C Preferred Stock has preference or
priority in the payment of dividends, when and if issued (collectively, "Junior
Dividend Stock"), and no dividend (other than dividends payable solely in stock
that is Junior Dividend Stock and that ranks junior to the AIG Series C
Preferred Stock as to distributions of assets upon liquidation, dissolution or
winding up of AIG, whether voluntary or involuntary (such stock that is junior
as to liquidation rights, "Junior Liquidation Stock") (the AIG Common Stock and
any other capital stock of AIG that is both Junior Dividend Stock and Junior
Liquidation Stock, "Junior Stock")) may be paid on any Junior Dividend Stock,
and no payment may be made on account of the purchase, redemption, retirement,
or other acquisition of Junior Dividend Stock or Junior Liquidation Stock (other
than in exchange solely for Junior Stock), unless all accrued and unpaid
dividends on the AIG Series C Preferred Stock for the then current period and
all dividend payment periods ending on or before the date of payment of such
dividends on Junior Dividend Stock, or such payment for such Junior Dividend
Stock or Junior Liquidation Stock, as the case may be, have been paid or
declared and set apart for payment. AIG may not pay dividends on the AIG Series
C Preferred Stock unless it has paid or declared and set apart for payment or
contemporaneously pays or declares and sets apart for payment all accrued and
unpaid dividends for all dividend payment periods on any class or series of
stock having parity with the AIG Series C Preferred Stock as to dividends
("Parity Dividend Stock") ratably, so that the amount of dividends declared and
paid per share on the AIG Series C Preferred Stock and such Parity Dividend
Stock will bear to each other the same ratio that the accrued and unpaid
dividends to the date of payment on AIG Series C Preferred Stock and such Parity
Dividend Stock bear to each other. No payment may be made on account of the
purchase, redemption, retirement or other acquisition of shares of Parity
Dividend Stock or other class or series of AIG's capital stock ranking on a
parity with the AIG Series C Preferred Stock as to distributions of assets upon
liquidation, dissolution or winding up of AIG, whether voluntary or involuntary
(such stock that has parity with the AIG Series C Preferred Stock as to
liquidation rights, "Parity Liquidation Stock") (other than such acquisitions
pursuant to employee or director or incentive or benefit plans or arrangements,
or in exchange solely for Junior Stock) unless all accrued and unpaid dividends
on the AIG Series C Preferred Stock for all dividend payment periods ending on
or before the date of payment on account of such acquisition of such Parity
Dividend Stock or Parity Liquidation Stock shall have been paid or declared and
set apart for payment.
 
     The amount of dividends payable per share of AIG Series C Preferred Stock
for each quarterly dividend period will be computed by dividing the annual
dividend amount by four. The amount of dividends payable for any period shorter
than a full quarterly dividend period will be computed on the basis of a 360-day
year of twelve 30-day months. No interest will be payable in respect of any
dividend payment on the AIG Series C Preferred Stock which may be in arrears.
 
     Under Delaware law, dividends (as well as other distributions) may be paid
on the capital stock of AIG only out of its capital surplus (that is, the excess
of AIG's net assets over the aggregate par value of all shares of capital stock
issued by AIG) or out of its net profits for the year in which the dividend is
declared and for the preceding year. See "Comparative Rights of Common
Shareholders -- Dividends." As AIG is a holding company with no significant
business operations, its primary sources of cash are dividends from its
insurance
 
                                       59

<PAGE>   68
 
subsidiaries. Its insurance subsidiaries' ability to pay dividends without prior
regulatory approval is limited by applicable laws and regulations.
 
  Liquidation Rights
 
     In the case of the voluntary or involuntary liquidation, dissolution or
winding up of AIG, holders of shares of AIG Series C Preferred Stock are
entitled to receive the liquidation preference of $50 per share, plus an amount
equal to any accrued and unpaid dividends to the payment date, before any
payment or distribution is made to the holders of AIG Common Stock or any Junior
Liquidation Stock, but the holders of the shares of the AIG Series C Preferred
Stock will not be entitled to receive the liquidation preference of such shares
until the liquidation preference of any other series or class of stock hereafter
issued that ranks senior as to liquidation rights to the AIG Series C Preferred
Stock ("Senior Liquidation Stock") has been paid in full. The holders of AIG
Series C Preferred Stock and all series or classes of stock hereafter issued
that rank on a parity as to distributions of assets upon such liquidation,
dissolution or winding up of AIG with the AIG Series C Preferred Stock are
entitled to share ratably, in accordance with the respective preferential
amounts payable on such stock, in any distribution (after payment of the
liquidation preference of the Senior Liquidation Stock) which is not sufficient
to pay in full the aggregate of the amounts payable thereon. After payment in
full of the liquidation preference on shares of the AIG Series C Preferred
Stock, the holders of such shares will not be entitled to any further
participation in any distribution of assets by AIG. Neither a consolidation nor
merger of AIG with another corporation nor a sale or transfer of all or
substantially all of AIG's property or assets will be considered a liquidation,
dissolution or winding up of AIG.
 
  Voting Rights
 
     The holders of the AIG Series C Preferred Stock will not have voting rights
except as described below or as required by law. In exercising any such vote,
each outstanding share of AIG Series C Preferred Stock will be entitled to one
vote, excluding shares held by AIG or any entity controlled by AIG, which shares
shall have no voting rights.
 
     Whenever dividends on the AIG Series C Preferred Stock or any outstanding
shares of Parity Dividend Stock have not been paid in an aggregate amount equal
to as least six quarterly dividends on such shares (whether or not consecutive),
the number of members of the AIG Board will be increased by two, and the holders
of the AIG Series C Preferred Stock, voting separately as a class with the
holders of Parity Dividend Stock on which like voting rights have been conferred
and are exercisable, will be entitled to elect such two additional directors who
shall continue to serve so long as such dividends remain in arrears. Such voting
rights will terminate when all such dividends accrued and unpaid have been
declared and paid or set apart for payment. The term of office of all directors
so elected will terminate immediately upon the termination of such voting rights
and the number of members of the AIG Board will be reduced by two.
 
     In addition, so long as any AIG Series C Preferred Stock is outstanding,
AIG will not, without the affirmative vote or consent of the holders of at least
66 2/3% of all outstanding shares of AIG Series C Preferred Stock and
outstanding Parity Dividend Stock (voting as a single class), (i) amend, alter
or repeal (by merger or otherwise) any provision of the AIG Certificate or the
AIG Bylaws so as to affect adversely the relative rights, preferences,
qualifications, limitations, or restrictions of the AIG Series C Preferred
Stock, (ii) effect any reclassification of the AIG Series C Preferred Stock, or
(iii) issue shares of AIG Preferred Stock to the extent that doing so would
cause the total number of shares of AIG Preferred Stock outstanding after giving
effect to such issuance to exceed 3,500,000.
 
     In addition to voting rights (if any) to which shares of AIG Series C
Preferred Stock are entitled pursuant to the DGCL, the holders of the
outstanding shares of AIG Series C Preferred Stock shall be entitled to vote as
a class if shareholder voting of the AIG Series C Preferred Stock would be
required by the FBCA (assuming AIG were then incorporated under the FBCA) upon a
proposed amendment to the AIG Certificate (or upon a plan of merger or share
exchange if such plan contains any provision that would, if contained in a
proposed amendment to the AIG Certificate, entitle such holders to vote as a
class as described in this paragraph), if the amendment would: (a) increase or
decrease the aggregate number of authorized
 
                                       60

<PAGE>   69
 
shares of AIG Preferred Stock; (b) effect an exchange or reclassification of all
or part of the shares of AIG Preferred Stock into shares of another class; (c)
effect an exchange or reclassification, or create a right of exchange, of all or
part of the shares of another class into shares of AIG Preferred Stock; (d)
change the designation, rights, preferences, or limitations of all or part of
the shares of AIG Preferred Stock; (e) change the shares of all or part of the
AIG Preferred Stock into a different number of shares of AIG Preferred Stock;
(f) create a new class of shares having rights or preferences with respect to
distributions or to dissolution that are prior, superior, or substantially equal
to the shares of AIG Preferred Stock; (g) increase the rights, preferences, or
number of authorized shares of any class that, after giving effect to the
amendment, have rights or preferences with respect to distributions or to
dissolution that are prior, superior, or substantially equal to the shares of
AIG Preferred Stock; (h) limit or deny an existing preemptive right of all or
part of the shares of AIG Preferred Stock; (i) cancel or otherwise affect rights
to distributions or dividends that have accumulated but not yet been declared on
all or part of the shares of AIG Preferred Stock.
 
     If a proposed amendment to the AIG Certificate would affect the shares of
AIG Series C Preferred Stock in one or more of the ways described in the
preceding paragraph, the shares of AIG Series C Preferred Stock shall be
entitled to vote as a separate class on the proposed amendment. If a proposed
amendment to the AIG Certificate that would entitle the shares of AIG Series C
Preferred Stock and one or more other series of AIG Preferred Stock to vote as
separate classes as described in the preceding sentence or paragraph (assuming
AIG were then incorporated under the FBCA) would affect shares of AIG Series C
Preferred Stock and such one or more other series of AIG Preferred Stock in the
same or a substantially similar way, the shares of AIG Series C Preferred Stock
and the shares of such one or more other series of AIG Preferred Stock so
affected shall vote together as a single class on the proposed amendment. The
shares of AIG Series C Preferred Stock shall also be entitled to any other
voting rights afforded by Florida law (assuming AIG were then incorporated under
the FBCA).
 
  Redemption at Option of AIG
 
     The AIG Series C Preferred Stock may not be redeemed prior to August 7,
2000. On or after such date, the AIG Series C Preferred Stock may be redeemed by
AIG, at its option, in whole or in part at any time, subject to the limitations,
if any, imposed by the FBCA (assuming AIG were then incorporated under the
FBCA), at a cash redemption price of $51.88 per share, plus accrued and unpaid
dividends to but excluding the redemption date, if redeemed on or prior to
August 6, 2001, and at the following redemption prices per share, if redeemed
during the 12-month period ending August 6:

and thereafter at $50 per share plus, in each case, accrued and unpaid dividends
to but excluding the redemption date. If fewer than all the outstanding shares
of AIG Series C Preferred Stock are to be redeemed, AIG will select those shares
to be redeemed pro rata or by lot or in such other manner as the AIG Board may
determine to be fair. There is no mandatory redemption or sinking fund
obligation with respect to the AIG Series C Preferred Stock. If at any time
dividends on the AIG Series C Preferred Stock are in arrears, AIG may not redeem
less than all of the then outstanding shares of the AIG Series C Preferred Stock
until all accrued dividends for all past dividend periods have been paid in
full.
 
     Notice of redemption will be mailed at least 30 days but not more than 90
days before the date fixed for redemption to each holder of record of shares of
AIG Series C Preferred Stock to be redeemed at the address shown on the stock
transfer books. No fractional shares of AIG Series C Preferred Stock will be
issued upon a redemption of less than all of the AIG Series C Preferred Stock,
but in lieu thereof, an appropriate amount
 
                                       61

<PAGE>   70
 
will be paid in cash based on the value for the shares of AIG Series C Preferred
Stock as determined in good faith by the AIG Board. After the date fixed for
redemption, dividends will cease to accrue on the shares of AIG Series C
Preferred Stock called for redemption and other rights of the holders of such
shares will terminate, except the right to receive the redemption price without
interest, and all conversion privileges will terminate on the business day prior
to the date fixed for redemption.
 
  Conversion Rights
 
     The holder of any shares of AIG Series C Preferred Stock will have the
right, at the holder's option, to convert any or all shares into AIG Common
Stock at any time at a conversion rate (subject to adjustment as described
below) equal to $50 divided by a conversion price (the "conversion price") of
$25.0325 (such conversion price to be adjusted following the Merger by
multiplying it by a fraction of which the numerator shall be the Purchaser Stock
Price and the denominator shall be the Applicable Price (each as defined) except
that if the AIG Series C Preferred Stock is called for redemption, the
conversion right will terminate at 5:00 p.m. New York City time on the business
day prior to the date fixed for such redemption and if not exercised prior to
such time, such conversion right will be lost, unless AIG defaults in making the
payment due upon redemption. Except as provided in the next paragraph, no
payment or adjustment will be made upon any conversion of any share of AIG
Series C Preferred Stock or on account of any dividends on the AIG Common Stock
issued upon conversion (except that if a converting holder of AIG Series C
Preferred Stock is eligible for a dividend on both the AIG Series C Preferred
Stock and AIG Common Stock issued upon conversion, the holder is entitled to the
higher of such dividend amounts). Following conversion, the holder will no
longer have any right to payment of dividends on the shares surrendered for
conversion. No fractional shares of AIG Common Stock will be issued upon
conversion but, in lieu thereof, an appropriate amount will be paid in cash
based on the reported last sale price for the shares of AIG Common Stock on the
NYSE on the day of such conversion.
 
     If AIG, by dividend or otherwise, declares or makes a distribution on the
AIG Common Stock referred to in clause (iv) or (v) of the next following
paragraph, the holders of the AIG Series C Preferred Stock, upon the conversion
thereof subsequent to the close of business on the date fixed for the
determination of shareholders entitled to receive such distribution and prior to
the effectiveness of the conversion price adjustment in respect of such
distribution, will be entitled to receive for each share of AIG Common Stock
into which each such share of AIG Series C Preferred Stock is converted the
portion of the shares of AIG Common Stock, rights, warrants, evidences of
indebtedness, shares of capital stock, cash and assets so distributed applicable
to one share of AIG Common Stock; provided, however, that AIG may, with respect
to all holders so converting, in lieu of distributing any portion of such
distribution not consisting of cash or securities of AIG, pay such holder cash
equal to the fair market value thereof (as determined by the AIG Board).
 
     The conversion price will be subject to adjustment in certain events
including, without duplication: (i) dividends (and other distributions) payable
in AIG Common Stock on any class of capital stock of AIG; (ii) the issuance to
all holders of AIG Common Stock of rights or warrants entitling holders of such
rights or warrants to subscribe for or purchase AIG Common Stock at less than
the then current market price (as defined); (iii) subdivisions and combinations
of AIG Common Stock; (iv) distributions to all holders of AIG Common Stock of
evidences of indebtedness of AIG, shares of capital stock, cash or assets
(including securities, but excluding those rights, warrants, dividends and
distributions referred to above and dividends and distributions paid exclusively
in cash); and (v) distributions consisting of cash, excluding (A) cash that is
part of a distribution referred to in (iv) above, and (B) any cash representing
an amount per share of AIG Common Stock of any quarterly cash dividend to the
extent it does not exceed the amount per share of AIG Common Stock of the next
preceding quarterly cash dividend (as adjusted to reflect any of the events
referred to in clauses (i) through (v) of this sentence) or all of such
quarterly cash dividends if the amount thereof per share of AIG Common Stock
multiplied by four does not exceed 15% of the current market price (as defined)
of AIG Common Stock on the trading day (as defined) next preceding the date of
declaration of such dividend. Following certain adjustments to the conversion
price, notice of such event will be mailed to the holders of the AIG Series C
Preferred Stock.

     In the event AIG adopts a shareholder rights plan that affords holders of
AIG Common Stock the right to purchase shares of AIG Common Stock, or shares of
common stock of a corporation that enters into certain business combinations or
other transactions with AIG, following the occurrence of certain triggering
events, the adoption of such plan and the distribution of such rights shall not
require any of the adjustments contemplated by the preceding paragraph, provided
that (a) if and so long as such rights are attached to shares of AIG Common
Stock pursuant to the terms of such rights plan, shares of AIG Common Stock
issued upon the conversion of shares of AIG Series C Preferred Stock shall have
attached to them such rights in the amount then attached to each outstanding
share of AIG Common Stock, and (b) in the event that such rights separate from
the AIG Common Stock and become exercisable pursuant to such rights plan, there
shall then be deemed to have occurred an issuance of rights for which adjustment
would be made as described in the preceding paragraph.
 
     The foregoing adjustments to the conversion price are designed to
compensate the holders of the AIG Series C Preferred Stock for the value of the
cash, securities or other assets that they would have otherwise received had
they converted their AIG Series C Preferred Stock into shares of AIG Common
Stock prior to such distribution. Such adjustment would generally result in a
reduced conversion price, which would entitle the holders of AIG Series C
Preferred Stock to receive a greater number of shares of AIG Common Stock upon
conversion of the AIG Series C Preferred Stock into AIG Common Stock.
 
     AIG from time to time may reduce the conversion price by any amount for any
period of time of at least 20 days, in which case AIG shall give at least 15
days' notice of such reduction, if the AIG Board has made a determination that
such reduction would be in the best interest of AIG, which determination shall
be conclusive.
 
     In the event that AIG is a party to any transaction (including, without
limitation, a merger, consolidation, sale of all or substantially all of AIG's
assets, recapitalization or reclassification of the AIG Common Stock (each of
the foregoing being referred to as an "AIG Transaction")), in each case (except
in the case of a Common Stock Fundamental Change (as defined)) as a result of
which shares of AIG Common Stock shall be converted into the right to receive
securities, cash or other property, each share of the AIG Series C Preferred
Stock shall thereafter be convertible into the kind and amount of securities,
cash and other property receivable upon the consummation of such AIG Transaction
by a holder of that number of shares of AIG Common Stock into which one share of
the AIG Series C Preferred Stock was convertible immediately prior to such AIG
Transaction (or in the case of a Common Stock Fundamental Change, common stock
of the kind received by the holders of AIG Common Stock as a result of such
Common Stock Fundamental Change) (but after giving effect to any adjustment
discussed in the next paragraph relating to a Fundamental Change (as defined) if
such AIG Transaction constitutes a Fundamental Change, and subject to funds
being legally available for such purpose under applicable law at the time of
such conversion).
 
     Notwithstanding any other provision in the preceding paragraphs to the
contrary, if any Fundamental Change occurs, then the conversion price in effect
will be adjusted immediately after such Fundamental Change as described below.
In addition, in the event of a Common Stock Fundamental Change, each share of
the AIG Series C Preferred Stock shall be convertible solely into common stock
of the kind received by holders of AIG Common Stock as the result of such Common
Stock Fundamental Change. For purposes of calculating any adjustment to be made
pursuant to this paragraph in the event of a Fundamental Change, immediately
after such Fundamental Change:
 
          (i) in the case of a Non-Stock Fundamental Change (as defined), the
     conversion price of the AIG Series C Preferred Stock will thereupon become
     the lower of (A) the conversion price in effect immediately prior to such
     Non-Stock Fundamental Change, but after giving effect to any other prior
     adjustments, and (B) the result obtained by multiplying the greater of the
     Applicable Price or the then applicable Reference Market Price (as defined)
     by a fraction of which the numerator will be $50 and the denominator will
     be the then current redemption price per share (or, for periods prior to
     August 7, 2000, an amount per share determined in accordance with the AIG
     Certificate); and
 
          (ii) in the case of a Common Stock Fundamental Change, the conversion
     price of the AIG Series C Preferred Stock in effect immediately prior to
     such Common Stock Fundamental Change, but after
 
                                       63

<PAGE>   72
 
     giving effect to any other prior adjustments, will thereupon be adjusted by
     multiplying such conversion price by a fraction, of which the numerator
     will be the Purchaser Stock Price and the denominator will be the
     Applicable Price; provided, however, that in the event of a Common Stock
     Fundamental Change in which (A) 100% of the value of the consideration
     received by a holder of AIG Common Stock is common stock of the successor,
     acquiror or other third party (and cash, if any, is paid with respect to
     any fractional interests in such common stock resulting from such Common
     Stock Fundamental Change) and (B) all of the AIG Common Stock will have
     been exchanged for, converted into, or acquired for, common stock (and cash
     with respect to fractional interests) of the successor, acquiror or other
     third party, the conversion price of the AIG Series C Preferred Stock in
     effect immediately prior to such Common Stock Fundamental Change will
     thereupon be adjusted by dividing such conversion price by the number of
     shares of common stock of the successor, acquiror, or other third party
     received by a holder of one share of AIG Common Stock as a result of such
     Common Stock Fundamental Change.
 
     The foregoing conversion price adjustments in the event of a Non-Stock
Fundamental Change will apply in situations whereby all or substantially all of
the AIG Common Stock is acquired in a transaction in which 50% or less of the
value received by holders of AIG Common Stock consists of common stock that has
been admitted for listing on a national securities exchange or quoted on the
Nasdaq National Market. If the market price of the AIG Common Stock immediately
prior to a Non-Stock Fundamental Change is lower than the applicable conversion
price of the AIG Series C Preferred Stock then in effect, the conversion price
will be adjusted as described in (i) above and the holders of the AIG Series C
Preferred Stock will be entitled to receive the amount and kind of consideration
that would have been received if the AIG Series C Preferred Stock had been
converted into AIG Common Stock prior to the Non-Stock Fundamental Change after
giving effect to such adjustment.
 
     The foregoing conversion price adjustments in the event of a Common Stock
Fundamental Change will apply in situations whereby more than 50% of the value
received by holders of AIG Common Stock consists of common stock of another
company that has been admitted for listing on a national securities exchange or
quoted on the Nasdaq National Market, in which case the AIG Series C Preferred
Stock will become convertible into shares of common stock of the other company.
If consideration for the AIG Common Stock consists partly of common stock of
another company and partly of other securities, cash or property, each share of
AIG Series C Preferred Stock will be convertible solely into a number of shares
of such common stock determined so that the initial value of such shares
(measured as described in the definition of Purchaser Stock Price below) equals
the value of the shares of AIG Common Stock into which such share of AIG Series
C Preferred Stock Price was convertible immediately before the transaction
(measured as described in the definition of Applicable Price below). If
consideration for AIG Common Stock is solely common stock of another company,
each share of AIG Series C Preferred Stock will be convertible into the same
number of shares of such common stock receivable by a holder of the number of
shares of AIG Common Stock into which such share of AIG Series C Preferred Stock
was convertible immediately before such transaction.
 
     Depending upon whether the Fundamental Change is a Non-Stock Fundamental
Change or a Common Stock Fundamental Change, a holder may receive significantly
different consideration upon conversion. In the event of a Non-Stock Fundamental
Change, the holder has the right to convert each share of the AIG Series C
Preferred Stock into the kind and amount of shares of stock and other securities
or property or assets receivable by a holder of the number of shares of AIG
Common Stock issuable upon conversion of such share of the AIG Series C
Preferred Stock immediately prior to such Non-Stock Fundamental Change, but
after giving effect to the adjustment described above. However, in the event of
a Common Stock Fundamental Change in which less than 100% of the value of the
consideration received by a holder of AIG Common Stock is common stock of the
acquiror or other third party, a holder of a share of the AIG Series C Preferred
Stock who converts a share following the Common Stock Fundamental Change will
receive consideration in the form of such common stock only, whereas a holder
who has converted his share prior to the Common Stock Fundamental Change will
receive consideration in the form of common stock as well as any other
securities or assets (which may include cash) receivable thereupon by a holder
of the number of shares of AIG Common Stock issuable upon conversion of such
share of AIG Series C Preferred Stock immediately prior to such Common Stock
Fundamental Change.

     The term "Applicable Price" means (i) in the event of a Non-Stock
Fundamental Change in which the holders of the AIG Common Stock receive only
cash, the amount of cash received by the holder of one share of AIG Common Stock
and (ii) in the event of any other Non-Stock Fundamental Change or any Common
Stock Fundamental Change, the average of the Closing Prices (as defined) for the
AIG Common Stock during the ten trading days prior to and including the record
date for the determination of the holders of AIG Common Stock entitled to
receive cash, securities, property or other assets in connection with such Non-
Stock Fundamental Change or Common Stock Fundamental Change, or, if there is no
such record date, the date upon which the holders of the AIG Common Stock shall
have the right to receive such cash, securities, property or other assets, in
each case, as adjusted in good faith by the AIG Board to reflect appropriately
any of the events referred to in clauses (i) through (v) of the third paragraph
of this Conversion Rights subsection.
 
     The term "Closing Price" of any common stock means on any day the last
reported sale price regular way on such day or in case no sale takes place on
such day, the average of the reported closing bid and asked prices regular way
in each case on the New York Stock Exchange or, if the common stock is not
listed or admitted to trading on such Exchange, on the principal national
securities exchange or quotation system on which the common stock is listed or
admitted to trading or quoted, or, if not listed or admitted to trading or
quoted on any national securities exchange or quotation system, the average of
the closing bid and asked prices in the over-the-counter market on such day as
reported by the National Quotation Bureau Incorporated, or a similarly generally
accepted reporting service, or, if not so available in such manner, as furnished
by any New York Stock Exchange Member firm selected by AIG for that purpose.
 
     The term "Common Stock Fundamental Change" means any Fundamental Change in
which more than 50% of the value (as determined in good faith by the AIG Board)
of the consideration received by holders of AIG Common Stock consists of common
stock that for each of the ten consecutive trading days referred to in the
second preceding paragraph has been admitted for listing or admitted for listing
subject to notice of issuance on a national securities exchange or quoted on the
Nasdaq National Market, provided, however, that a Fundamental Change shall not
be a Common Stock Fundamental Change unless either (i) AIG continues to exist
after the occurrence of such Fundamental Change and the outstanding shares of
AIG Series C Preferred Stock continue to exist as outstanding AIG Series C
Preferred Stock, or (ii) not later than the occurrence of such Fundamental
Change, the outstanding shares of AIG Series C Preferred Stock are converted
into or exchanged for shares of convertible preferred stock of a corporation
succeeding to the business of AIG, which convertible preferred stock has powers,
preferences and relative, participating, optional or other rights, and
qualifications, limitations and restrictions, substantially similar to those of
the AIG Series C Preferred Stock.
 
     The term "Fundamental Change" means the occurrence of any transaction or
event in connection with a plan pursuant to which all or substantially all of
the AIG Common Stock shall be exchanged for, converted into, acquired for or
constitute solely the right to receive cash, securities, property or other
assets (whether by means of an exchange offer, liquidation, tender offer,
consolidation, merger, combination, reclassification, recapitalization or
otherwise) provided, in the case of a plan involving more than one such
transaction or event, for purposes of adjustment of the conversion price, such
Fundamental Change shall be deemed to have occurred when substantially all of
the AIG Common Stock shall be exchanged for, converted into, or acquired for or
constitute solely the right to receive cash, securities, property or other
assets, but the adjustment shall be based upon the highest weighted average per
share consideration which a holder of AIG Common Stock could have received in
such transactions or events as a result of which more than 50% of the AIG Common
Stock shall have been exchanged for, converted into, or acquired for or
constitute solely the right to receive cash, securities, property or other
assets.
 
     The term "Non-Stock Fundamental Change" means any Fundamental Change other
than a Common Stock Fundamental Change.
 
     The term "Purchaser Stock Price" means, with respect to any Common Stock
Fundamental Change, the average of the Closing Prices for the common stock
received in such Common Stock Fundamental Change for the ten consecutive trading
days prior to and including the record date for the determination of the holders
of AIG Common Stock entitled to receive such common stock, or if there is no
such record date, the date upon
 
                                       65

<PAGE>   74
 
which the holders of the AIG Common Stock shall have the right to receive such
common stock, in each case, as adjusted in good faith by the AIG Board to
appropriately reflect any of the events referred to in clauses (i) through (v)
of the third paragraph of this subsection; provided, however,that if no such
Closing Prices exist, the Purchaser Stock Price shall be set at a price
determined in good faith by the AIG Board.
 
     The term "Reference Market Price" shall mean $13.46 and in the event of any
adjustment to the conversion price other than as a result of a Fundamental
Change, the Reference Market Price shall also be adjusted so that the ratio of
the Reference Market Price to the conversion price after giving effect to any
such adjustment shall always be the same ratio of $13.46 to the initial
conversion price specified in the first sentence of this subsection.
 
     Notwithstanding the foregoing provisions, the issuance of any shares of AIG
Common Stock pursuant to any plan providing for the reinvestment of dividends or
interest payable on securities of AIG and the investment of additional optional
amounts in shares of AIG Common Stock under any such plan, and the issuance of
any shares of AIG Common Stock or options or rights to purchase such shares
pursuant to any employee benefit plan or program of AIG or pursuant to any
option, warrant, right or exercisable, exchangeable or convertible security
outstanding as of the date the AIG Series C Preferred Stock was first designated
(other than the occurrence of certain events under a shareholder rights plan),
and any issuance of rights under a shareholder rights plan shall not be deemed
to constitute an issuance of AIG Common Stock or exercisable, exchangeable or
convertible securities by AIG to which any of the adjustment provisions
described above applies. There shall also be no adjustment of the conversion
price in case of the issuance of any stock (or securities convertible into or
exchangeable for stock) of AIG, except as specifically described above. If any
action would require adjustment of the conversion price pursuant to more than
one of the provisions described above, only one adjustment shall be made and
such adjustment shall be the amount of adjustment which has the highest absolute
value to holders of the AIG Series C Preferred Stock. No adjustment in the
conversion price will be required unless such adjustment would require an
increase or decrease of at least 1% of the conversion price, but any adjustment
that would otherwise be required to be made shall be carried forward and taken
into account in any subsequent adjustment.
 
  Lack of Established Market for the AIG Series C Preferred Stock
 
     There is currently no public market for the AIG Series C Preferred Stock.
Although an application will be made prior to the Effective Time for the listing
of the AIG Series C Preferred Stock on the NYSE, there can be no assurance that
an active market for the AIG Series C Preferred Stock will develop or that, if
the AIG Series C Preferred Stock is approved for such listing, such listing will
continue while the AIG Series C Preferred Stock is outstanding. Future trading
prices for the AIG Series C Preferred Stock will depend on many factors,
including, among others, AIG's financial results, the market for similar
securities and the volume of trading activity in the AIG Series C Preferred
Stock.
 
                   COMPARATIVE RIGHTS OF COMMON SHAREHOLDERS
 
     AIG is incorporated under the laws of the State of Delaware. American
Bankers is incorporated under the laws of the State of Florida. The holders of
shares of Common Stock whose rights as shareholders are currently governed by
Florida law, the American Bankers Articles, and the American Bankers Bylaws,
will, upon the exchange of their shares pursuant to the Merger, become holders
of shares of AIG Common Stock, and their rights as such will be governed by
Delaware law, the AIG Certificate and the AIG Bylaws. The material differences
between the rights of holders of shares of Common Stock and the rights of
holders of shares of AIG Common Stock, which result from differences in their
governing corporate documents and differences in Delaware and Florida corporate
law, are summarized below.
 
     The following summary is not intended to be complete and is qualified in
its entirety by reference to the FBCA, the DGCL, the American Bankers Articles,
the American Bankers Bylaws, the AIG Certificate and the AIG Bylaws, as
appropriate. The identification of specific differences is not meant to indicate
that other equally or more significant differences do not exist. Copies of the
American Bankers Articles, the American Bankers Bylaws, the AIG Certificate and
the AIG Bylaws are incorporated by reference herein and will be
 
                                       66

sent to holders of Common Stock upon request. See "Incorporation of Certain
Documents by Reference" and "Available Information."
 
AUTHORIZED CAPITAL
 
     The American Bankers Articles provide for authorized stock consisting of
100,000,000 shares of Common Stock, $1.00 par value and 10,000,000 shares of
Preferred Stock, no par value, of which (i) 350,000 have been authorized as
Series A Participating Preferred Stock and (ii) 2,300,000 have been authorized
as $3.125 Series B Cumulative Convertible Preferred Stock.
 
     The AIG Certificate provides for authorized stock consisting of
1,000,000,000 shares of AIG Common Stock, $2.50 par value, and 6,000,000 shares
of AIG Preferred Stock, $5.00 par value, of which 2,300,000 shares have been
authorized as AIG Series C Preferred Stock.
 
ELECTION AND SIZE OF BOARD OF DIRECTORS
 
     The FBCA requires that a board of directors consist of one or more natural
persons, or as set forth in a corporation's articles of incorporation or bylaws.
The FBCA permits staggered boards of directors of up to three separate classes
if authorized in the articles of incorporation. The American Bankers Articles
provide for a classified board of directors, consisting of three classes of
directors: Class I, Class II, and Class III. The American Bankers Articles state
that the number of directors in each class shall be as nearly equal in number as
possible. Each class is elected in successive years for a term of three years.
 
     The American Bankers Articles fix the number of directors at not less than
twelve nor more than eighteen. Currently, there are 15 directors. The American
Bankers Articles provide that the number of directors shall be increased by two
directors elected by the holders of the Preferred Stock if quarterly dividends
are in arrears for six quarters or more, whether consecutive or not.
 
     Nominations for the American Bankers Board may be made by the American
Bankers Board or by any shareholder entitled to vote for the election of
directors and who complies with certain notice provisions in the American
Bankers Articles.
 
     Under Delaware law, directors, unless their terms are staggered, are
elected at each annual shareholder meeting. Vacancies on the board of directors
may be filled by the shareholders or directors, unless the certificate of
incorporation or a bylaw provides otherwise. The certificate of incorporation
may authorize the election of certain directors by one or more classes or series
of shares, and the certificate of incorporation, an initial bylaw or a bylaw
adopted by a vote of the shareholders may provide for staggered terms for the
directors. The certificate of incorporation or the bylaws also may allow the
shareholders or the board of directors to fix or change the number of directors,
but a corporation must have at least one director. Under Delaware law,
shareholders do not have cumulative voting rights unless the certificate of
incorporation so provides.
 
     The AIG Bylaws provide that directors are elected by a plurality of votes
at annual meetings and hold office until the annual meeting of shareholders next
succeeding their election until successors are elected and qualified or until
their earlier resignation or removal.
 
     The AIG Certificate provides that the number of directors shall be fixed in
the manner provided in the AIG Bylaws. The AIG Bylaws fix the number of
directors at not less than seven nor more than 21. Currently there are 17
directors. The AIG Bylaws provide that the size of the AIG Board may be
increased by the vote of a majority of directors then in office, although less
than a quorum, or by the affirmative vote of the holders of a majority of the
outstanding shares of all classes of stock entitled to vote thereon.
 
REMOVAL OF DIRECTORS
 
     The FBCA entitles shareholders to remove directors either for cause or
without cause, unless the articles of incorporation provide that removal may be
for cause only. Directors elected by a particular voting group may only be
removed by the shareholders of that voting group. The American Bankers Articles
provide that
 
                                       67

<PAGE>   76
 
any director may be removed, but only for cause and at a regular shareholders
meeting or a shareholders meeting called for that express purpose, by a vote of
the holders of 75% or more of the outstanding shares of the capital stock of
American Bankers then entitled to vote at an election of directors. No decrease
in the number of directors shall shorten the term of any incumbent director.
 
     Under the DGCL, a director of a corporation that does not have a classified
board of directors or cumulative voting may be removed (with or without cause)
with the approval of a majority of the outstanding shares entitled to vote. The
AIG Bylaws provide that any director may be removed, with or without cause, by
the holders of a majority of the shares entitled to vote at an election of
directors.
 
VACANCIES ON THE BOARD OF DIRECTORS
 
     The FBCA provides that, unless the articles provide otherwise, vacancies
arising on the board of directors may be filled by a majority of the remaining
directors, even if no quorum remains, or by the shareholders. When directors are
divided into classes, vacancies may be filled by the shareholders or, if at
least one director remains in the class, by the remaining directors of that
class. Where a vacancy will be known to occur at some point in the future, it
may be filled in advance, although the new director will not take office until
the vacancy actually occurs. The American Bankers Articles provide that any
vacancies on the American Bankers Board occurring for any reason or from the
creation of new directorships shall be filled by the affirmative vote of a
majority of the remaining directors in the class in which the vacancy occurs,
or, if none so remain, by a majority vote of the directors of the other two
classes. Directors so appointed hold office until the next regularly scheduled
election of directors for that class.
 
     Under Delaware law, the board of directors of a corporation may fill any
vacancy on the board, including vacancies resulting from an increase in the
number of directors. The AIG Bylaws provide that any vacancy created by the
removal of directors with or without cause by holders of a majority of shares
entitled to vote at an election of directors may be filled by the same majority
(or by a majority of the holders of a class or series of shares where such class
or series is entitled to elect one or more of the directors of the class from
which directors were so removed.) Other vacancies and newly created
directorships resulting from any increase in the authorized number of directors
elected by all of the shareholders having a right to vote as a single class or
from any other cause may be filled by a majority of directors then in office,
although less than a quorum, or by the sole remaining director. Whenever the
holders of any class or series of stock are entitled to elect one or more
directors, vacancies and newly created directorships of such class or series
may, unless otherwise provided in the AIG Certificate, be filled by a majority
of the directors elected by such class or series thereof then in office, or by
the sole remaining director so elected.
 
ACTION BY WRITTEN CONSENT
 
     The FBCA allows shareholders or all of the directors to take action without
a meeting through the use of a written consent unless provided otherwise in the
articles of incorporation. The American Bankers Articles provide that action of
shareholders may only be taken at properly called annual or special meetings of
shareholders and that shareholders may not act by written consent.
 
     Delaware law provides that, unless limited by the certificate of
incorporation, any action that could be taken by shareholders at a meeting may
be taken without a meeting if a consent (or consents) in writing, setting forth
the action so taken, is signed by the holders of record of outstanding stock
having not less than the minimum number of votes that would be necessary to
authorize or take such action at a meeting at which all shares entitled to vote
thereon were present and voted. The AIG Bylaws provide that any action which is
required by law to be taken or which may be taken at any meeting of
shareholders, may be taken without a meeting, without prior notice and without a
vote, by consent in writing of shareholders having not less than the minimum
number of votes that would be necessary to take the action at a meeting. Prompt
notice of an action taken by written consent which is not unanimous is required
to be given to those shareholders who do not consent.

AMENDMENTS TO CHARTER
 
     Any amendment, alteration, change or repeal of the articles dealing with
the composition of the American Bankers Board (Article V), the approval of
certain business combinations (Article VIII), meetings of shareholders (Article
IX) and the amendment procedure (Article X), require the approval of at least
85% of the shares eligible to vote, including at least 50% of the shares
eligible to vote other than those held by a 30% Shareholder (as defined in the
American Bankers Articles), except where such change has been recommended to the
shareholders by at least a majority of the American Bankers Board and by at
least two-thirds of the continuing directors. Amendments to any other sections
of the American Bankers Articles are governed by the FBCA, which generally
requires approval by a majority of the shareholders entitled to vote thereon.
 
     Under Delaware law, unless a higher vote is required in the certificate of
incorporation, an amendment to the certificate of incorporation of a corporation
may be approved by a majority of the outstanding shares entitled to vote upon
the proposed amendment. The AIG Certificate provides AIG with the right to
amend, alter, change or repeal any provision contained in the AIG Certificate in
the manner prescribed by law and states that the rights and powers conferred
therein on shareholders, directors and officers are subject to such reserved
power.
 
AMENDMENTS TO BYLAWS
 
     Under the FBCA, bylaws may be amended by the directors or the shareholders
unless the articles of incorporation expressly provide that only shareholders
may do so. Bylaws adopted by the shareholders may provide that they may not be
amended or repealed by the directors. The American Bankers Bylaws may be
repealed or amended and new bylaws may be adopted by either the majority vote of
the full American Bankers Board or by the holders of a majority of the
outstanding stock entitled to vote thereon. The American Bankers Board may not
amend or repeal any bylaw adopted by the shareholders if the shareholders
specifically provide that it is not subject to amendment or repeal by the
American Bankers Board.
 
     The DGCL provides that a corporation's bylaws may be amended by that
corporation's shareholders, or, if so provided in the corporation's certificate
of incorporation, the power to amend the corporation's bylaws may also be
conferred on the corporation's directors. The AIG Certificate gives its
directors the power to make, alter, amend, change, add to or repeal the AIG
Bylaws. The AIG Bylaws provide that they may be amended or repealed, and new
bylaws may be adopted, by the affirmative vote of a majority of the AIG Board,
but the holders of a majority of the shares then entitled to vote may adopt
additional bylaws and may amend or repeal any bylaw whether or not adopted by
them.
 
SPECIAL MEETINGS OF SHAREHOLDERS
 
     Under the FBCA, a special meeting of shareholders may be called by a
corporation's board of directors or any other person authorized to do so in the
articles of incorporation or bylaws. Special meetings may also be called on
demand of at least 10% of all shares eligible to vote on the matter to be
considered, although this percentage may be increased in the articles of
incorporation to a maximum of 50%. Only business within the purpose of the
special meeting notice may be conducted at such meeting. The American Bankers
Articles provide that special meetings may be called by the holders of at least
75% of the Voting Shares (as defined in the American Bankers Articles) or as
otherwise provided in the bylaws. The American Bankers Bylaws provide that
special meetings of shareholders may be held at any place within or without the
State of Florida, and may be called by the American Bankers Board, the Executive
Committee, the Chief Executive Officer or when requested in writing by the
holders of 75% of the Voting Shares, as defined in the American Bankers
Articles.
 
     Delaware law provides that special meetings of the shareholders of a
corporation may be called by the corporation's board of directors or by such
other persons as may be authorized in the corporation's certificate of
incorporation or bylaws. The AIG Bylaws provide that special meetings of
shareholders may be held at any place within or without the State of Delaware,
and may be called by the Chairman, a Vice Chairman, if any, the President, if
any, the Secretary or the AIG Board and shall be called by the Secretary upon
the written
 
                                       69

<PAGE>   78
 
request of shareholders who together own of record 25% or more of the
outstanding shares of each class of stock entitled to vote at such meeting.
 
VOTE ON EXTRAORDINARY CORPORATE TRANSACTIONS
 
     Under the FBCA, and subject to certain exceptions (including those
described in "--Business Combination Restrictions"), the approval of a merger,
plan of liquidation or sale of all or substantially all of a corporation's
assets other than in the regular course of business requires the recommendation
of the corporation's board of directors and an affirmative vote of at least 50%
of the shareholders eligible to vote thereon. The American Bankers Articles
require, in addition to the approvals mandated by law, the approval by the
holders of at least 85% of the outstanding shares of capital stock eligible to
vote, which shall include the affirmative vote of at least 50% of the Voting
Shares (as defined in the American Bankers Articles) held by shareholders other
than any 30% Shareholder, to approve any of the following transactions:
 
     - Any merger or consolidation of American Bankers or a subsidiary thereof
       with a 30% Shareholder or any corporation that would be an affiliate of a
       30% Shareholder;
 
     - Any sale, lease, exchange, mortgage, pledge, transfer or other
       disposition to or with any 30% Shareholder of any assets with a value of
       $5,000,000 or more;
 
     - The issuance or transfer by American Bankers or a subsidiary thereof of
       any stock or securities to any 30% Shareholder with a value in $5,000,000
       or more;
 
     - The adoption of any proposal or plan of liquidation or dissolution; or
 
     - Any reclassification of securities, recapitalization, reorganization,
       merger or other consolidation or any similar transaction which has the
       effect of increasing the proportionate shares owned directly or
       indirectly by any 30% Shareholder.
 
     The American Bankers Articles eliminate this shareholder approval
requirement where the American Bankers Board has, by at least a 75% vote of the
members then in office, approved the 30% Shareholders' acquisition of 30% or
more of the outstanding shares of Common Stock or has approved the business
combination prior to the 30% Shareholder having become a 30% Shareholder.
Alternatively, the shareholder approval described above is not required when a
series of conditions, including the mailing of a proxy statement to the holders
of all shares eligible to vote, are met. Because the American Bankers Board
approved the Merger Agreement, the Stock Option Agreement, the Voting Agreement
and the Merger, this provision will not be applicable thereto.
 
     Delaware law provides that, unless otherwise specified in a corporation's
certificate of incorporation or unless the provisions of Delaware law relating
to business combinations discussed below under "-- Business Combination
Restrictions" are applicable, a sale or other disposition of all or
substantially all of the corporation's assets, a merger or consolidation of the
corporation with another corporation or a dissolution of the corporation
requires the affirmative vote of the board of directors (except in certain
limited circumstances) plus, with certain exceptions, the affirmative vote of a
majority of the outstanding stock entitled to vote thereon. The foregoing
provisions apply to AIG. The AIG Certificate does not contain vote requirements
for extraordinary corporate transactions in addition to the approvals mandated
by law.
 
INSPECTION OF DOCUMENTS
 
     Under the FBCA, a shareholder is entitled to inspect and copy the articles
of incorporation, bylaws, certain board and shareholder resolutions, certain
written communications to shareholders, a list of the names and business
addresses of the corporation's directors and officers, and the corporation's
most recent annual report, during regular business hours if the shareholder
gives at least five business days' prior written notice to the corporation. In
addition, a shareholder of a Florida corporation is entitled to inspect and copy
other books and records of the corporation during regular business hours if the
shareholder gives at least five business days' prior written notice to the
corporation and (1) the shareholder's demand is made in good faith and for a
proper purpose, (2) the demand describes with particularity its purpose and the
records to be inspected or copied and
 
                                       70

<PAGE>   79
 
(3) the requested records are directly connected with such purpose. The FBCA
also provides that a corporation may deny any demand for inspection if the
demand was made for an improper purpose or if the demanding shareholder has,
within two years preceding such demand, sold or offered for sale any list of
shareholders of the corporation or any other corporation, has aided or abetted
any person in procuring a list of shareholders for such purpose or has
improperly used any information secured through any prior examination of the
records of the corporation or any other corporation.
 
     The DGCL allows any shareholder, upon written demand under oath stating the
purpose thereof, the right during the usual hours for business to inspect for
any proper purpose the corporation's stock ledger, a list of its shareholders,
and its other books and records, and to make copies or extracts therefrom. A
proper purpose means a purpose reasonably related to such person's interest as a
shareholder.
 
DIVIDENDS
 
     The FBCA permits a corporation's board of directors to make distributions
to its shareholders so long as the corporation is not left unable to pay its
debts as they become due in the ordinary course of business, or the corporation
is not left with total assets that are less than the sum of the corporation's
total liabilities plus its obligations upon dissolution to satisfy preferred
shareholders whose preferential rights are superior to those receiving the
distribution. Under the FBCA, a corporation's redemption of its own capital
stock is deemed to be a distribution.
 
     The American Bankers Articles provide that the Preferred Stock is entitled
to receive, when, as and if declared by the American Bankers Board, dividends at
the rate of $3.125 per annum per share, which are fully cumulative. No dividends
or other distributions, other than stock dividends, may be paid on shares of
Common Stock, unless and until all accrued and unpaid dividends for the
Preferred Stock for all dividend periods are paid or set aside and declared for
payment.
 
     Subject to any restrictions contained in a corporation's certificate of
incorporation, Delaware law generally provides that a corporation may declare
and pay dividends out of "surplus" (defined as the excess, if any, of net assets
(total assets less total liabilities) over capital) or, when no surplus exists,
out of net profits for the fiscal year in which the dividend is declared and/or
the preceding fiscal year, except that dividends may not be paid out of net
profits if the capital of the corporation is less than the amount of capital
represented by the issued and outstanding stock of all classes having a
preference upon the distribution of assets. In accordance with the DGCL,
"capital" is determined by the board of directors and shall not be less than the
aggregate par value of the outstanding capital stock of the corporation having
par value.
 
     The AIG Bylaws provide that the AIG Board may, out of funds legally
available and at any regular or special meeting, declare dividends upon the
capital stock of AIG as and when it deems expedient. All outstanding classes of
AIG Preferred Stock, including the AIG Series C Preferred Stock, shall rank
senior to the AIG Common Stock in respect of the right to receive dividends.
 
APPRAISAL RIGHTS OF DISSENTING SHAREHOLDERS
 
     The FBCA provides that unless a corporation's articles of incorporation
provide otherwise, which American Banker's Articles do not, a shareholder does
not have dissenters' rights with respect to a plan of merger, share exchange or
proposed sale or exchange of property if the shares held by the shareholder are
either registered on a national securities exchange or designated as a national
market systems security on an interdealer quotation system designated by the
NASD or held of record by 2,000 or more shareholders. Consequently, appraisal
rights are not available to holders of Common Stock or Preferred Stock in
connection with the Merger. See "The Merger -- Absence of Appraisal Rights."
 
     Under Delaware law, in certain circumstances a shareholder of a Delaware
corporation is generally entitled to demand appraisal and obtain payment of the
judicially determined fair value of his or her shares in the event of any plan
of merger or consolidation to which the corporation, the shares of which he or
she holds, is a party, provided such shareholder continuously holds such shares
through the effective date of the merger, otherwise complies with the
requirement of Delaware law for the perfection of appraisal rights and does not
 
                                       71

<PAGE>   80
 
vote in favor of the merger. However, this right to demand appraisal does not
apply to shareholders if: (1) they are shareholders of a surviving corporation
and if a vote of the shareholders of such corporation is not necessary to
authorize the merger or consolidation; and (2) the shares held by the
shareholders are of a class or series registered on the NYSE or the American
Stock Exchange (the "ASE"), designated as a national market system security on
an interdealer quotation system by the NASD or are held of record by more than
2,000 shareholders on the date set to determine the shareholders entitled to
vote on the merger or consolidation. Notwithstanding the above, appraisal rights
are available for the shares of any class or series of stock of a Delaware
corporation if the holders thereof are required by the terms of an agreement of
merger or consolidation to accept for their stock anything except: (i) shares of
stock of the corporation surviving or resulting from the merger or
consolidation; (ii) shares of stock of any other corporation which at the
effective date of the merger or consolidation will be listed on the NYSE or the
ASE, designated as a national market system security on an interdealer quotation
system by the NASD or held of record by more than 2,000 shareholders; (iii) cash
in lieu of fractional shares of the corporations described in (i) and (ii); or
(iv) any combination of the shares of stock and cash in lieu of fractional
shares described in (i), (ii) and (iii).
 
     A Delaware corporation may provide in its certificate of incorporation that
appraisal rights shall be available for the shares of any class or series of its
stock as the result of an amendment to its certificate of incorporation, any
merger or consolidation to which the corporation is a party or a sale of all or
substantially all of the assets of the corporation. The AIG Certificate does not
contain any provision regarding appraisal rights.
 
INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     The FBCA permits a corporation to indemnify officers, directors, employees
and agents for actions taken in good faith and in a manner they reasonably
believed to be in, or not opposed to, the best interests of the corporation, and
with respect to any criminal action, which they had no reasonable cause to
believe was unlawful. The FBCA provides that a corporation may advance
reasonable expenses of defense (upon receipt of an undertaking to reimburse the
corporation if indemnification is ultimately determined not to be appropriate)
and must reimburse a successful defendant for expenses, including attorneys'
fees, actually and reasonably incurred. The FBCA also permits a corporation to
purchase liability insurance for its directors, officers, employees and agents.
The FBCA provides that indemnification may not be made for any claim, issue or
matter as to which a person has been adjudged by a court of competent
jurisdiction to be liable to the corporation, unless and only to the extent a
court determines that the person is entitled to indemnity for such expenses as
the court deems proper. In the Merger Agreement, AIG has agreed to continue the
indemnification rights of officers and directors of American Bankers with
respect to matters existing or occurring prior to the Effective Time and to
continue directors and officers liability insurance coverage, as described above
in "The Merger Agreement -- Certain Other Covenants." The American Bankers
Articles provide for indemnification for any present or former director or
officer to the fullest extent permitted by the FBCA.
 
     Under Delaware law, a corporation may indemnify any person made a party or
threatened to be made a party to any type of proceeding (other than an action by
or in the right of the corporation) because he is or was an officer, director,
employee or agent of the corporation or was serving at the request of the
corporation as a director, officer, employee or agent of another corporation or
entity, against expenses, judgments, costs and amounts paid in settlement
actually and reasonably incurred in connection with such proceeding: (1) if he
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the corporation; or (2) in the case of a
criminal proceeding, he had no reasonable cause to believe that his conduct was
unlawful. A corporation may indemnify any person made a party or threatened to
be made a party to any threatened, pending or completed action or suit brought
by or in the right of the corporation because he was an officer, director,
employee or agent of the corporation, or is or was serving at the request of the
corporation as a director, officer, employee or agent of another corporation or
other entity, against expenses actually and reasonably incurred in connection
with such action or suit if he acted in good faith and in a manner he reasonably
believed to be in or not opposed to the best interests of the corporation,
except that there may be no such indemnification if the person is found liable
to the corporation unless, in such a case, the court determines the person is
entitled thereto. A corporation must indemnify a director, officer, employee or
agent against expenses actually and reasonably incurred by him who successfully
defends himself in a proceeding to
 
                                       72

<PAGE>   81
 
which he was a party because he was a director, officer, employee or agent of
the corporation. Expenses incurred by an officer or director (or other employees
or agents as deemed appropriate by the board of directors) in defending a civil
or criminal proceeding may be paid by the corporation in advance of the final
disposition of such proceeding upon receipt of an undertaking by or on behalf of
such director or officer to repay such amount if it shall ultimately be
determined that he is not entitled to be indemnified by the corporation. The
Delaware law indemnification and expense advancement provisions are not
exclusive of any other rights which may be granted by the bylaws, a vote of
shareholders or disinterested directors, agreement or otherwise.
 
     The AIG Certificate provides for the indemnification to the fullest extent
permitted by law of any person made, or threatened to be made, a party to an
action, suit or proceeding (whether, civil, criminal, administrative or
investigative) by reason of the fact that he or his testator or intestate is or
was a director, officer or employee of AIG or serves or served any other
enterprise at the request of AIG.
 
LIMITATION OF LIABILITY
 
     The FBCA provides that a director is not personally liable for monetary
damages to the corporation or any other person for any statement, vote,
decision, or failure to act, regarding corporate management or policy unless the
director breached or failed to perform his statutory duties as a director and
such breach or failure (1) constitutes a violation of criminal law, unless the
director had reasonable cause to believe his conduct was lawful or had no
reasonable cause to believe his conduct was unlawful, (2) constitutes a
transaction from which the director derived an improper personal benefit, (3)
results in an unlawful distribution, (4) in a derivative action or an action by
a shareholder, constitutes conscious disregard for the best interests of the
corporation or willful misconduct or (5) in a proceeding other than a derivative
action or an action by a shareholder, constitutes recklessness or an act or
omission which was committed in bad faith or with malicious purpose or in a
manner exhibiting wanton and willful disregard of human rights, safety or
property.
 
     Delaware law permits a corporation to adopt a provision in its certificate
of incorporation eliminating or limiting the personal liability of a director to
the corporation or its shareholders for monetary damages for beach of fiduciary
duty as a director, except that such provision shall not limit the liability of
a director for (i) any breach of the director's duty of loyalty to the
corporation or its shareholders, (ii) acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii)
liability under Section 174 of the DGCL for unlawful payment of dividends or
stock purchases or redemptions, or (iv) any transaction from which the director
derived an improper personal benefit. The AIG Certificate provides that no
director of AIG shall be liable to it or its shareholders for monetary damages
for breach of fiduciary duly as a director, except to the extent such an
exemption from liability or limitation thereof is not permitted under the DGCL.
 
PREEMPTIVE RIGHTS
 
     Under the FBCA, shareholders of a corporation have no preemptive rights
unless provided for in the articles of incorporation. The American Bankers
Articles contain no provision for preemptive rights.
 
     Delaware law does not provide (except in limited instances) for preemptive
rights to acquire a corporation's unissued stock. However, such right may be
expressly granted to the shareholders in a corporation's certificate or articles
of incorporation. The AIG Certificate provides that holders of AIG Common Stock
and AIG Series C Preferred Stock are not entitled to preemptive rights.
 
SPECIAL REDEMPTION PROVISIONS
 
     The FBCA permits a corporation to acquire its own shares. Shares of
Preferred Stock are subject to optional redemption by American Bankers at any
time after August 7, 2000.
 
     Under the DGCL, a corporation may purchase or redeem shares of any class of
its capital stock, but subject generally to the availability of sufficient
lawful funds therefor and provided that at all times, at the time of any such
redemption, the corporation shall have outstanding shares of one or more classes
or series of
 
                                       73

<PAGE>   82
 
capital stock which have full voting rights that are not subject to redemption.
The AIG Certificate contains no provision for special redemptions of shares of
its capital stock.
 
PREFERRED STOCK PURCHASE RIGHTS
 
     The American Bankers Board has adopted the Rights Agreement, pursuant to
which one preferred stock purchase right (a "Right" or "Rights") was issued with
respect to each share of Common Stock. As a result of the two-for-one split of
Common Stock paid on September 12, 1997, one-half of a Right is associated with
each share of Common Stock. Each right entitles the registered holder thereof to
purchase 1/100th of a share of Series A Participating Preferred Stock at a price
of $33.00 per share, subject to adjustment (the "Purchase Price").
 
     The Rights are represented by the Common Stock share certificates and are
not exercisable until a Distribution Date and will expire at the close of
business on March 10, 1998. A Distribution Date is defined as the earlier of the
following: (i) ten (10) days following the date of public announcement by
American Bankers or an Acquiring Person (as defined below) that an Acquiring
Person has become such or (ii) ten (10) business days after the date that a
tender or exchange offer by any person is first published or given within the
meaning of Rule 14d-2(a) of General Rules and Regulation under the Exchange Act,
if upon consummation thereof such person would be the beneficial owner of 15% or
more of the shares of Common Stock then outstanding. An Acquiring Person is any
person who or which, together with all Affiliates and Associates of such person
(as defined in the Rights Agreement), is the beneficial owner of 15% or more of
the shares of Common Stock then outstanding. The Rights will first become
exercisable on a Distribution Date, unless earlier redeemed or exchanged, and
may then begin trading separately.
 
     Each holder of a Right (other than those owned by the Acquiring Person,
which shall be void) will have the right to receive upon exercise that number of
shares of Common Stock (or, if applicable, common stock of the entity surviving
any business combination with American Bankers or which acquires American
Bankers) having a market value of two times the then current Purchase Price of
one Right in the event of certain mergers, acquisitions and other transactions
as specified in the Rights Agreement.
 
     On December 19, 1997, the Rights Agreement was amended as described above
in "Related Agreements and Transactions -- Amendment to American Bankers' Rights
Agreement". Therefore, the Rights Agreement will be inapplicable to the Merger
Agreement, the Stock Option Agreement, the Voting Agreement and the Merger. In
the Merger Agreement, American Bankers has agreed, if requested by AIG prior to
the Effective Time, that the American Bankers Board will take all necessary
action to terminate or redeem all of the outstanding Rights and to terminate the
Rights Agreement, effective immediately prior to the Effective Time.
 
     Delaware case law authorizes Delaware corporations to issue stock purchase
rights. The AIG Board has not adopted a shareholder rights agreement.
 
SHAREHOLDER SUITS
 
     Under the FBCA, a person may not bring a derivative action unless the
person was a shareholder of the corporation at the time of the challenged
transaction or unless the person acquired his shares by operation of law from a
person who was a shareholder at such time.
 
     Under Delaware law, a shareholder may institute a lawsuit against one or
more directors, either on his own behalf, or derivatively on behalf of the
corporation. An individual shareholder may also commence a lawsuit on behalf of
himself and other similarly situated shareholders when the requirements for
maintaining a class action under Delaware law have been met.
 
BUSINESS COMBINATION RESTRICTIONS
 
     Section 607.0901 of the FBCA provides that the approval of the holder of
two-thirds of the voting shares of a company, other than the shares beneficially
owned by an Interested Shareholder (as defined below), would be required to
effectuate certain transactions, including without limitation a merger,
consolidation,
 
                                       74

<PAGE>   83
 
certain sales of assets, certain sales of shares, liquidation or dissolution of
the corporation, and reclassification of securities involving a corporation and
an Interested Shareholder (an "Affiliated Transaction"). An "Interested
Shareholder" is defined as the beneficial owner of more than 10% of the voting
shares outstanding. The foregoing special voting requirement is in addition to
the vote required by any other provision of the FBCA or the provision in
American Bankers Articles described above.
 
     The special voting requirement does not apply in any of the following
circumstances: (i) the Affiliated Transaction is approved by a majority of the
corporation's disinterested directors; (ii) the Interested Shareholder has owned
at least 80% of the corporation's voting stock for five years; (iii) the
Interested Shareholder owns more than 90% of the corporation's voting shares;
(iv) the corporation has not had more than 300 shareholders of record at any
time during the three years preceding the announcement of the event; (v) the
corporation is an investment company registered under the Investment Company Act
of 1940; (vi) all of the following conditions are met: (a) the cash and fair
value of other consideration to be paid per share to all holders of voting
shares equals the highest per share price paid by the Interested Shareholder;
(b) the consideration to be paid in the Affiliated Transaction is in the same
form as previously paid by the Interested Shareholder (or certain alternative
benchmarks if higher); (c) during the portion of the three years proceeding the
announcement date that the Interested Shareholder has been an Interested
Shareholder, except as approved by a majority of the disinterested directors,
there shall have been no default in payment of any full periodic dividends, no
decrease in common stock dividends, no increase in the voting shares owned by
the Interested Shareholder, (d) during such three year period no benefit to the
Interested Shareholder in the form of loans, guaranties or other financial
assistance or tax advantages provided by the corporation, and (e) unless
approved by a majority of the disinterested directors, a proxy shall have been
mailed to holders of voting shares at least 25 days prior to the consummation of
the Affiliated Transaction. Because the American Bankers Board unanimously
approved the Merger Agreement, the Stock Option Agreement, the Voting Agreement
and the Merger, this provision will not be applicable thereto.
 
     The American Bankers Bylaws provide that the Florida Control Share
Acquisitions Statute (FBCA sec.607.0902) does not apply to control-share
acquisitions of stock of American Bankers occurring on or after November 14,
1990.
 
     In general, Section 203 of the DGCL prevents an "Interested Shareholder"
(defined generally as a person with 15% or more of a corporation's outstanding
voting stock, with the exception of any person who owned and has continued to
own shares in excess of the 15% limitation since December 23, 1987) from
engaging in a Business Combination with a Delaware corporation for three years
following the date such person became an Interested Shareholder. The term
"Business Combination" includes mergers or consolidations with an Interested
Shareholder and certain other transactions with an Interested Shareholder,
including, without limitation: (i) any sale, lease, exchange, mortgage, pledge,
transfer or other disposition (except proportionately as a shareholder of such
corporation) to or with the Interested Shareholder of assets (except
proportionately as a shareholder of the corporation) having an aggregate market
value equal to 10% or more of the aggregate market value of all assets of the
corporation or of certain subsidiaries thereof determined on a consolidated
basis or the aggregate market value of all the outstanding stock of the
corporation; (ii) any transaction which results in the issuance or transfer by
the corporation or by certain subsidiaries thereof of stock of the corporation
or such subsidiary to the Interested Shareholder, except pursuant to certain
transfers in a conversion or exchange or pro rata distribution to all
shareholders of the corporation or certain other transactions, none of which
increase the Interested Shareholder's proportionate ownership of any class or
series of the corporation's or such subsidiary's stock; (iii) any transaction
involving the corporation or certain subsidiaries thereof which has the effect,
directly or indirectly, of increasing the proportionate share of the stock of
any class or series, or securities convertible into stock of the corporation or
any subsidiary which is owned by the Interested Shareholder (except as a result
of immaterial changes due to fractional share adjustments or as a result of any
purchase or redemption of any shares of stock not caused directly or indirectly
by the Interested Shareholder); or (iv) any receipt by the Interested
Shareholder of the benefit (except proportionately as a shareholder of such
corporation) of any loans, advances, guarantees, pledges, or other financial
benefits provided by or through the corporation or certain subsidiaries.
 
                                       75

<PAGE>   84
 
     The three-year moratorium may be avoided if: (i) before such person became
an Interested Shareholder, the board of directors of the corporation approved
either the Business Combination or the transaction in which the Interested
Shareholder became an Interested Shareholder, or (ii) upon consummation of the
transaction which resulted in the shareholder becoming an Interested
shareholder, the shareholder owned at least 85% of the voting stock of the
corporation outstanding at the time the transaction commenced (excluding shares
held by directors who are also officers of the corporation and by employee stock
ownership plans that do not provide employees with the right to determine
confidentially whether shares held subject to the plan will be tendered in a
tender or exchange offer); or (iii) on or following the date on which such
person became an Interested Shareholder, the Business Combination is approved by
the board of directors of the corporation and authorized at an annual or special
meeting of shareholders (not by written consent) by the affirmative vote of the
shareholders of at least 66 2/3% of the outstanding voting stock of the
corporation not owned by the Interested Shareholder.
 
     The Business Combination restrictions described above do not apply if,
among other things: (i) the corporation's original certificate of incorporation
contains a provision expressly electing not to be governed by the statute; (ii)
the corporation by action by the holders of a majority of the voting stock of
the corporation approves an amendment to its certificate of incorporation or
bylaws expressly electing not to be governed by the statute (effective twelve
(12) months after the amendment's adoption), which amendment shall not be
applicable to any business combination with a person who was an Interested
Shareholder at or prior to the time of the amendment; or (iii) the corporation
does not have a class of voting stock that is (a) listed on a national
securities exchange, (b) authorized for quotation on Nasdaq or a similar
quotation system; or (c) held of record by more than 2,000 shareholders. The
statute also does not apply to certain Business Combinations with an Interested
Shareholder when such combination is proposed after the public announcement of,
and before the consummation or abandonment of, a merger or consolidation, a sale
of 50% or more of the aggregate market value of the assets of the corporation on
a consolidated basis or the aggregate market value of all outstanding shares of
the corporation, or a tender offer for 50% or more of the outstanding voting
shares of the corporation, if the triggering transaction is with or by a person
who either was not an Interested Shareholder during the previous three years or
who became an Interested Shareholder with Board of Director approval, and if the
transaction is approved or not opposed by a majority of the current directors
who were also directors prior to any person becoming an Interested Shareholder
during the previous three years. AIG is subject to the Business Combination
restrictions described above. The AIG Certificate does not contain a provision
electing not to be governed by the Business Combination restrictions.
 
                                 LEGAL MATTERS
 
     The validity of the shares of AIG Series C Preferred Stock and AIG Common
Stock to be issued in connection with the Merger will be passed upon for AIG by
Kathleen E. Shannon, Esq., Vice President and Associate General Counsel of AIG.
 
     Sullivan & Cromwell, counsel to AIG, and Jorden Burt Berenson & Johnson
LLP, counsel to American Bankers, will deliver opinions concerning certain
federal income tax consequences of the Merger.
 
                                    EXPERTS
 
     The consolidated financial statements and schedules of AIG at December 31,
1996 and 1995 and for the three year period ended December 31, 1996 incorporated
by reference in this Proxy Statement/Prospectus have been audited by Coopers &

collectively referred to as the "Constituent Corporations.")
 
                                    RECITALS
 
     WHEREAS, the respective boards of directors of each of Parent, Merger

and into Merger Subsidiary (the "Merger") upon the terms and subject to the
conditions set forth in this Agreement is advisable and have approved the
Merger;
 
     WHEREAS, it is intended that, for federal income tax purposes, the Merger
shall qualify as a reorganization under the provisions of Section 368(a) of the
Internal Revenue Code of 1986, as amended, and the rules and regulations
promulgated thereunder (the "Code"); and
 
     WHEREAS, concurrently with the execution and delivery of this Agreement and
as a condition and inducement to Parent's willingness to enter into this
Agreement, the Company and Parent have entered into a Stock Option Agreement
dated as of the date of this Agreement and attached hereto as Exhibit A (the
"Stock Option Agreement"), pursuant to which the Company has granted Parent an
option to purchase shares of common stock of the Company under certain
circumstances;
 
     WHEREAS, concurrently with the execution and delivery of this Agreement and
as a condition and inducement to Parent's willingness to enter into this
Agreement, certain stockholders of the Company and Parent have entered into a

Exhibit B (the "Voting Agreement"), pursuant to which such stockholders have
agreed, among other things, to vote their shares of common stock of the Company
in favor of the Merger; and
 
     WHEREAS, the Company, Parent and Merger Subsidiary desire to make certain

accordance with this Agreement or (ii) at such other place and time and/or on
such other date as the Company and Parent may agree in writing (the "Closing
Date").

     (a) Common Stock Merger Consideration.  (i) Subject to paragraphs (ii) and
(iii) below, each share of Common Stock, par value $1.00 per share, of the
Company (a "Common Share" or, collectively, the "Common Shares") issued and
outstanding immediately prior to the Effective Time (other than Common Shares
owned by Parent, Merger Subsidiary or any other direct or indirect subsidiary of
Parent (collectively, the "Parent Companies") or Common Shares that are owned by
the Company or any direct or indirect subsidiary of the Company and in each case
not held on behalf of third parties (collectively, "Excluded Common Shares"))
shall be converted into, and become exchangeable for, that portion of a share of
Common Stock, par value $2.50 per share, of Parent ("Parent Common Stock") equal
to the lesser of (i) .4495 (the "Maximum Exchange Ratio") and (ii) the decimal
derived by dividing $47.00 by the average of the closing prices per share of
Parent Common Stock as reported on the NYSE composite transactions reporting
system (as reported in the New York City edition of the Wall Street Journal) for
the ten trading days ending on the

<PAGE>   92
 
third trading day prior to the date of the consummation of the Merger (the "Base
Period Stock Price"); provided, however, if the Base Period Stock Price is below
$104.5625, Parent shall elect to either (i) pay a cash amount equal to the Per
Share Cash Top-Up Amount (provided that Parent may not elect to pay the cash
amount contemplated by this clause (i) if the aggregate cash amount so paid
would exceed the Non-Election Cash Pool) or (ii) (x) increase the Maximum
Exchange Ratio (the "Adjusted Maximum Exchange Ratio") up to a decimal such that
the product of the Adjusted Maximum Exchange Ratio times the Base Period Stock
Price (the "Product") equals or is less than $47.00 and (y) if the Product is
less than $47.00, pay a cash amount equal to the difference between $47.00 and
such Product (provided that Parent may not elect to pay such an aggregate amount
of cash pursuant to this clause (ii) which would exceed the Non-Election Cash
Pool). The foregoing payments shall be referred to herein as the "Non-Election
Merger Consideration";
 
     (ii) Common Shares for which the holder of such shares has made a Cash
Election shall be converted into, and become exchangeable for, $47.00 in cash
(the "Cash Election Merger Consideration"), provided that in no event shall
holders of Common Shares who have made a Cash Election be entitled to receive an
aggregate amount of cash in excess of the Maximum Cash Pool. In the event that
Cash Elections are submitted with respect to an aggregate number of Common
Shares which, except for the limitation imposed by the Maximum Cash Pool, would
require Parent to pay cash in the aggregate in excess of the Maximum Cash Pool,
a pro rata portion of such Common Shares (rounded down to the nearest whole
Common Share) shall be converted into the right to receive the Cash Election
Merger Consideration, which proration as to each shareholder shall be based upon
the ratio of the (i) Maximum Cash Pool to (ii) the aggregate number of Common
Shares with respect to which Cash Elections are submitted multiplied by $47.00.
All Common Shares which are not converted into the right to receive the Cash
Election Merger Consideration as a result of this paragraph shall be converted
into the right to receive the Stock Election Merger Consideration;
 
     (iii) Common Shares for which a holder has made a Stock Election shall be
converted into, and become exchangeable for, that portion of a share of Parent
Common Stock equal to the lesser of (i) the Maximum Exchange Ratio and (ii) the
decimal derived by dividing $47.00 by the Base Period Stock Price; provided,
however, if the Base Period Stock Price is below $104.5625, Parent shall elect
to either (i) pay a cash amount equal to the Per Share Cash Top-Up Amount
(provided that Parent may not elect to pay the cash amount contemplated by this
clause (i) if the aggregate cash amount paid would exceed the Stock Election
Cash Pool) or (ii) (x) establish the Adjusted Maximum Exchange Ratio such that
the Product equals or is less than $47.00 and (y) if the Product is less than
$47.00, pay a cash amount equal to the difference between $47.00 and such
Product (provided that Parent may not elect to pay an aggregate amount of cash
pursuant to this clause (ii) which would exceed the Stock Election Cash Pool).
The foregoing payments shall be referred to herein as the "Stock Election Merger
Consideration" and, together with the Non-Election Merger Consideration and the
Cash Election Merger Consideration, the "Common Stock Merger Consideration."
 
     (iv) For purposes of this Agreement the following terms shall have the
following meanings:
 
          "Maximum Cash Pool" means an amount of cash equal to .499 multiplied
     by the amount of the Common Stock Merger Consideration, calculated for
     purposes of this definition based on the closing price of Parent Common
     Stock on the NYSE composite transactions reporting system on the trading
     day immediately preceding the Closing Date.
 
          "Non-Election Cash Pool" means an amount of cash equal to the Maximum
     Cash Pool minus the aggregate amount of cash paid in the Merger to the
     holders of Common Shares that make a Cash Election.
 
          "Stock Election Cash Pool" means an amount of cash equal to the
     greater of (i) $0 and (ii) the Aggregate Cash Top-Up Amount minus the
     aggregate amount of cash paid in the Merger to the holders of Common Shares
     that do not make a Stock Election.
 
          "Per Share Cash Top-Up Amount" means the greater of (i) $0 and (ii)
     (x) $47.00 minus (y) the product of (A) the Base Period Stock Price and (B)
     the Maximum Exchange Ratio.
 
                                       I-3

<PAGE>   93
 
          "Aggregate Cash Top-Up Amount" means the lesser of (i) the product of
     (x) the Per Share Cash Top-Up Amount and (y) the number of outstanding
     Common Shares as of the Effective Time and (ii) an amount equal to the
     Maximum Cash Pool.
 
     (b) Preferred Stock Merger Consideration.  Each share of $3.125 Series B
Convertible Preferred Stock, no par value, of the Company (a "Preferred Share"
or, collectively, the "Preferred Shares" and, together with the Common Shares,
the "Shares") issued and outstanding immediately prior to the Effective Time
(other than Preferred Shares owned by Parent Companies or Preferred Shares that
are owned by the Company or any direct or indirect subsidiary of the Company and
in each case not held on behalf of third parties (collectively, "Excluded
Preferred Shares" and, together with the Excluded Common Shares, the "Excluded
Shares") shall be converted into, and become exchangeable for one share (the
"Preferred Stock Merger Consideration," and, together with the Common Stock
Merger Consideration, the "Merger Consideration"), of Series C Preferred Stock,
par value $5.00 per share, of Parent ("Parent Preferred Stock") which shall
contain terms substantially similar to the terms of the Preferred Shares (after
making the conversion adjustments required to be made for a Common Stock
Fundamental Change pursuant to the Company's Third Amended and Restated Articles
of Incorporation as a result of the Merger) and shall be convertible into Parent
Common Stock.
 
     (c) Cancellation of Shares.  At the Effective Time, all Shares shall no
longer be outstanding and shall be canceled and retired and shall cease to
exist, and each certificate (a "Certificate") formerly representing any of such
Shares (other than Excluded Shares) shall thereafter represent only the right to
the Merger Consideration and the right, if any, to receive pursuant to Section
4.2(e) cash in lieu of fractional shares into which such Shares have been
converted pursuant to this Section 4.1(c) and any distribution or dividend
pursuant to Section 4.2(c). Each Share issued and outstanding immediately prior
to the Effective Time and owned by any of the Parent Companies or owned by the
Company or any direct or indirect subsidiary of the Company (in each case other
than Shares that are owned on behalf of third parties), shall, by virtue of the
Merger and without any action on the part of the holder thereof, cease to be
outstanding, shall be canceled and retired without payment of any consideration
therefor and shall cease to exist.
 
     (d) Merger Subsidiary.  At the Effective Time, each share of Common Stock,
par value $.01 per share, of Merger Subsidiary issued and outstanding
immediately prior to the Effective Time shall be converted into one share of
common stock of the Surviving Corporation.
 
     (e) Election Form.  Each holder of Common Shares will be entitled to elect
with respect to all or any portion of the Common Shares held by such holder to
have such shares converted at the Effective Time into the right to receive the
Stock Election Merger Consideration (the "Stock Election") or the Cash Election
Merger Consideration (the "Cash Election"). The form for making the Stock
Election and Cash Election (the "Election Form") shall be determined by mutual
agreement between Parent and the Company and shall be mailed to holders of
Common Shares on the record date for the Common Stockholders Meeting together
with the related Prospectus/Proxy Statement (as hereinafter defined). To be
effective, the Election Form must be properly completed, signed and submitted by
the Election Deadline (as hereinafter defined) to the Exchange Agent (as
hereinafter defined) and accompanied by the certificates representing the Common
Shares as to which an Election is being made or an appropriate guarantee of
delivery by a commercial bank or trust company in the United States or a member
of a registered national securities exchange or the National Association of
Securities Dealers, Inc.). An Election Form which is not effective shall be
treated as if no election had been made with respect to the Common Shares
covered by such Election Form and any holder who does not submit an effective
Election Form shall receive the Non-Election Merger Consideration. Parent will
have the discretion, which it may delegate in whole or in part to the Exchange
Agent, to determine whether Election Forms have been properly completed, signed
and submitted or revoked and to disregard immaterial defects in Election Forms.
The decisions of Parent or, if delegated, of the Exchange Agent shall be
conclusive and binding. Neither Parent, Merger Subsidiary nor the Exchange Agent
will be under any obligation to notify any person of any defect in an Election
Form submitted to the Exchange Agent. The Exchange Agent shall also make all
computations contemplated by Section 4.1(a) hereof, and all such computations
shall be conclusive and binding on the holders of Common Shares in the absence
of manifest error.
 
                                       I-4

     Parent and the Company each shall use its best efforts to make the Election
Form available to all persons who become holders of record of Common Shares
during the period between the record date for the Common Stockholders Meeting
and 5:00 P.M., New York City time, on the third trading day preceding such
meeting (the "Election Deadline"). If the date of such Common Stockholders
Meeting is postponed or such meeting is adjourned without approval of the
Merger, the Election Deadline shall be postponed until 5:00 P.M., New York City
time, on the tenth trading day preceding the day on which the Merger is actually
approved by the shareholders of the Company. A properly completed Election Form
must be received by the Exchange Agent by the Election Deadline in order to be
effective. Any Election Form may be revoked but only by written notice received
by the Exchange Agent prior to the Election Date.
 
     4.2.  Exchange of Certificates for Shares.
 
     (a) Exchange Agent.  Promptly after the Effective Time, Parent shall
deposit, or shall cause to be deposited, with an exchange agent selected by
Parent with the Company's prior approval, which shall not be unreasonably
withheld (the "Exchange Agent"), for the benefit of the holders of Shares,
certificates representing the shares of Parent Common Stock and Parent Preferred
Stock and, after the Effective Time, if applicable, any cash, dividends or other
distributions with respect to the Parent Common Stock and Parent Preferred Stock
to be issued or paid pursuant to this Agreement in exchange for Shares
outstanding immediately prior to the Effective Time upon due surrender of the
Certificates (or affidavits of loss in lieu thereof) pursuant to the provisions
of this Article IV (such certificates for shares of Parent Common Stock and
Parent Preferred Stock, together with the amount of any cash, dividends or other
distributions payable with respect thereto, being hereinafter referred to as the
"Exchange Fund").
 
     (b) Exchange Procedures.  Promptly after the Effective Time, the Surviving
Corporation shall cause the Exchange Agent to mail to each holder of record of
Shares (other than holders of Excluded Shares) (i) a letter of transmittal
specifying that delivery shall be effected, and risk of loss and title to the
Certificates shall pass, only upon delivery of the Certificates (or affidavits
of loss in lieu thereof) to the Exchange Agent, such letter of transmittal to be
in such form and have such other provisions as Parent and the Company may
reasonably agree, and (ii) instructions for use in effecting the surrender of
the Certificates in exchange for (A) certificates representing shares of Parent
Common Stock or Parent Preferred Stock, as applicable, and (B) if applicable,
any cash, unpaid dividends or other distributions and cash in lieu of fractional
shares. Subject to Section 4.2(h), upon surrender of a Certificate for
cancellation to the Exchange Agent together with such letter of transmittal,
duly executed, the holder of such Certificate shall be entitled to receive in
exchange therefor (x) a certificate representing that number of whole shares of
Parent Common Stock or Parent Preferred Stock, as applicable, that such holder
is entitled to receive pursuant to this Article IV, (y) a check in the amount
(after giving effect to any required tax withholdings) of (A) any cash in lieu
of fractional shares plus (B) any cash, including unpaid non-stock dividends and
any other dividends or other distributions, that such holder has the right to
receive pursuant to the provisions of this Article IV, and the Certificate so
surrendered shall forthwith be canceled. No interest will be paid or accrued on
any amount payable upon due surrender of the Certificates. In the event of a
transfer of ownership of Shares that is not registered in the transfer records
of the Company, a certificate representing the proper number of shares of Parent
Common Stock or Parent Preferred Stock, as applicable, together with a check for
any cash to be paid upon due surrender of the Certificate and any other
dividends or distributions in respect thereof, may be issued and/or paid to such
a transferee if the Certificate formerly representing such Shares is presented
to the Exchange Agent, accompanied by all documents required to evidence and
effect such transfer and to evidence that any applicable stock transfer taxes
have been paid. If any certificate for shares of Parent Common Stock or Parent
Preferred Stock, as applicable, is to be issued in a name other than that in
which the Certificate surrendered in exchange therefor is registered, it shall
be a condition of such exchange that the Person (as defined below) requesting
such exchange shall pay any transfer or other taxes required by reason of the
issuance of certificates for shares of Parent Common Stock or Parent Preferred
Stock, as applicable, in a name other than that of the registered holder of the
Certificate surrendered, or shall establish to the satisfaction of Parent or the
Exchange Agent that such tax has been paid or is not applicable.

     For the purposes of this Agreement, the term "Person" shall mean any
individual, corporation (including not-for-profit), general or limited
partnership, limited liability company, joint venture, estate, trust,
association, organization, Governmental Entity (as defined in Section 5.1(d)) or
other entity of any kind or nature.
 
     (c) Distributions with Respect to Unexchanged Shares.  All shares of Parent
Common Stock and Parent Preferred Stock to be issued pursuant to the Merger
shall be deemed issued and outstanding as of the Effective Time and whenever a
dividend or other distribution is declared by Parent in respect of the Parent
Common Stock or Parent Preferred Stock, as applicable, the record date for which
is at or after the Effective Time, that declaration shall include dividends or
other distributions in respect of all shares issuable pursuant to this
Agreement. No dividends or other distributions in respect of the Parent Common
Stock or Parent Preferred Stock, as applicable, shall be paid to any holder of
any unsurrendered Certificate until such Certificate is surrendered for exchange
in accordance with this Article IV. Subject to the effect of applicable laws,
following surrender of any such Certificate, there shall be issued and/or paid
to the holder of the certificates representing whole shares of Parent Common
Stock and Parent Preferred Stock, as applicable, issued in exchange therefor,
without interest, (A) at the time of such surrender, the dividends or other
distributions with a record date after the Effective Time theretofore payable
with respect to such whole shares of Parent Common Stock and Parent Preferred
Stock, as applicable, and not paid and (B) at the appropriate payment date, the
dividends or other distributions payable with respect to such whole shares of
Parent Common Stock and Parent Preferred Stock, as applicable, with a record
date after the Effective Time but with a payment date subsequent to surrender.
 
     (d) Transfers.  After the Effective Time, there shall be no transfers on
the stock transfer books of the Company of the Shares that were outstanding
immediately prior to the Effective Time.
 
     (e) Fractional Shares.  Notwithstanding any other provision of this
Agreement, no fractional shares of Parent Common Stock will be issued. Each
holder of Common Shares who would be entitled to receive a fractional share of
Parent Common Stock but for this Section 4.2(e) shall be entitled to receive, in
lieu thereof, a cash payment in an amount equal to such fractional share of
Parent Common Stock multiplied by the Base Period Stock Price.
 
     (f) Termination of Exchange Fund.  Any portion of the Exchange Fund
(including the proceeds of any investments thereof and any Parent Common Stock
and Parent Preferred Stock) that remains unclaimed by the stockholders of the
Company for 180 days after the Effective Time shall be paid to Parent. Any
stockholders of the Company who have not theretofore complied with this Article
IV shall thereafter look only to Parent for payment of their shares of Parent
Common Stock and Parent Preferred Stock, as applicable, and any cash, dividends
and other distributions in respect thereof payable and/or issuable pursuant to
Section 4.1 and Section 4.2(c) upon due surrender of their Certificates (or
affidavits of loss in lieu thereof), in each case, without any interest thereon.
Notwithstanding the foregoing, none of Parent, the Surviving Corporation, the
Exchange Agent or any other Person shall be liable to any former holder of
Shares for any amount properly delivered to a public official pursuant to
applicable abandoned property, escheat or similar laws.
 
     (g) Lost, Stolen or Destroyed Certificates.  In the event any Certificate
shall have been lost, stolen or destroyed, upon the making of an affidavit of
that fact by the Person claiming such Certificate to be lost, stolen or
destroyed and, if required by Parent, the posting by such Person of a bond in
customary amount as indemnity against any claim that may be made against it with
respect to such Certificate, the Exchange Agent will issue in exchange for such
lost, stolen or destroyed Certificate the shares of Parent Common Stock or
Parent Preferred Stock, as applicable, and any cash payable and any unpaid
dividends or other distributions in respect thereof pursuant to Section 4.1 and
4.2(c) upon due surrender of and deliverable in respect of the Shares
represented by such Certificate pursuant to this Agreement.
 
     (h) Affiliates.  Notwithstanding anything herein to the contrary,
Certificates surrendered for exchange by any "affiliate" (as determined pursuant
to Section 6.8) of the Company shall not be exchanged until Parent has received
a written agreement from such Person as provided in Section 6.8 hereof.
 
     4.3.  Dissenters' Rights.  In accordance with Section 607.1302 of the FBCA,
no appraisal rights shall be available to holders of Shares in connection with
the Merger.

<PAGE>   96
 
     4.4.  Adjustments to Prevent Dilution.  In the event that the Company
changes the number of Shares or securities convertible or exchangeable into or
exercisable for Shares, or Parent changes the number of shares of Parent Common
Stock or securities convertible or exchangeable into or exercisable for shares
of Parent Common Stock, issued and outstanding prior to the Effective Time as a
result of a reclassification, stock split (including a reverse split), stock
dividend or distribution, recapitalization, merger, subdivision or other similar
transaction, the Merger Consideration shall be equitably adjusted.
 
     4.5.  Treatment of the Convertible Notes.  The Convertible Notes (as
defined in Section 5.1(b)) shall be treated as set forth in Section 6.14.
 
                                   ARTICLE V
 
                         REPRESENTATIONS AND WARRANTIES
 
     5.1.  Representations and Warranties of the Company.  (i) Except as set
forth in the corresponding sections or subsections of the disclosure letter
delivered to Parent by the Company on or prior to entering into this Agreement
(the "Company Disclosure Letter") or in any Company Report (as hereinafter
defined) filed prior to the date hereof, the Company hereby represents and
warrants to Parent and Merger Subsidiary that:
 
     (a) Organization, Good Standing and Qualification.  The Company is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Florida and each of its Subsidiaries is a corporation duly
organized, validly existing and in good standing under the laws of its
respective jurisdiction of organization and each of the Company and its
Subsidiaries has all requisite corporate or similar power and authority to own
and operate its properties and assets and to carry on its business as presently
conducted and is qualified to do business and is in good standing as a foreign
corporation in each jurisdiction where the ownership or operation of its
properties or conduct of its business requires such qualification, except where
the failure to be so qualified or in good standing, when taken together with all
other such failures, is not reasonably likely to have a Company Material Adverse
Effect (as defined below). The Company has made available to Parent a complete
and correct copy of the Company's and its Subsidiaries' charter and by-laws,
each as amended to date. The Company's and its Subsidiaries' charter and by-laws
so delivered are in full force and effect.
 
     As used in this Agreement, the term (i) "Subsidiary" means, with respect to
the Company, Parent or Merger Subsidiary, as the case may be, any entity,
whether incorporated or unincorporated, of which at least a majority of the
securities or ownership interests having by their terms ordinary voting power to
elect a majority of the board of directors or other persons performing similar
functions is directly or indirectly owned or controlled by such party or by one
or more of its respective Subsidiaries or by such party and any one or more of
its respective Subsidiaries, and (ii) "Company Material Adverse Effect" means a
material adverse effect on the financial condition, properties, business or
results of operations of the Company and its Subsidiaries taken as a whole.
 
     The Company conducts its insurance operations through the Subsidiaries set
forth on Section 5.1(a) of the Company Disclosure Letter (collectively, the
"Company Insurance Subsidiaries"). Each of the Company Insurance Subsidiaries is
(i) duly licensed or authorized as an insurance company and, where applicable, a
reinsurer in its jurisdiction of incorporation, (ii) duly licensed or authorized
as an insurance company and, where applicable, a reinsurer in each other
jurisdiction where it is required to be so licensed or authorized, and (iii)
duly authorized in its jurisdiction of incorporation and each other applicable
jurisdiction to write each line of business reported as being written in the
Company SAP Statements (as hereinafter defined), except, in any such case, where
the failure to be so licensed or authorized is not reasonably likely to have a
Company Material Adverse Effect. The Company has made all required filings under
applicable insurance holding company statutes except where the failure to file
is not reasonably likely to have a Company Material Adverse Effect.
 
     (b) Capital Structure.  The authorized stock of the Company consists of
100,000,000 Common Shares, of which 41,535,807 Common Shares were outstanding as
of the close of business on November 3, 1997, and 10,000,000 shares of Preferred
Stock, no par value, of which (i) 350,000 shares have been authorized as
 
                                       I-7

<PAGE>   97
 
Series A Participating Preferred Stock, none of which were outstanding as of
December 21, 1997 and (ii) 2,300,000 shares have been authorized as Preferred
Shares, of which 2,300,000 Preferred Shares were outstanding as of December 21,
1997. All of the outstanding Common Shares and Preferred Shares have been duly
authorized and are validly issued, fully paid and nonassessable. The Company has
no commitments to issue or deliver Common Shares, except that, as of December
21, 1997, there were approximately 5,630,610 (but no more than 5,664,193) Common
Shares subject to issuance (i) pursuant to the Company's 1997 Equity Incentive
Plan, 1994 Amended and Restated Directors' Deferred Compensation Plan, 1994 Key
Executive Debenture Plan, 1994 Non-Employee Directors' Stock Option Plan, 1994
Senior Management Stock Option Plan, 1991 Stock Option/Restricted Stock Plan,
1991 Stock Incentive Plan, and 1987 Executive Stock Option/Dividend Accrual Plan
(collectively, the "Company Stock Plans") and (ii) upon conversion of the
Preferred Shares and the Company's convertible debenture bonds due May 24, 1999
("Convertible Notes"). The Company has no commitments to issue or deliver
preferred shares, except that as of December 21, 1997, there were 350,000 shares
of Series A Participating Preferred Stock subject to issuance pursuant to the
Rights Agreement, as amended and restated as of November 14, 1990, and as
further amended on December 19, 1997, between the Company and ChaseMellon
Shareholder Services, LLC (as successor to Manufacturers Hanover Trust Company),
as Rights Agent (the "Rights Agreement"). The Company Disclosure Letter contains
a correct and complete list of each outstanding option to purchase or acquire
Common Shares under each of the Company Stock Plans (each a "Company Option"),
including the plan, the holder, date of grant, exercise price and number of
Shares subject thereto. Each of the outstanding shares of capital stock or other
securities of each of the Company's Subsidiaries is duly authorized, validly
issued, fully paid and nonassessable and owned by the Company or a direct or
indirect wholly-owned subsidiary of the Company, free and clear of any lien,
pledge, security interest, claim or other encumbrance. Except as set forth above
and in the Stock Option Agreement, there are no preemptive or other outstanding
rights, options, warrants, conversion rights, stock appreciation rights,
redemption rights, repurchase rights, agreements, arrangements or commitments to
issue or sell any shares of capital stock or other securities of the Company or
any of its Subsidiaries or any securities or obligations convertible or
exchangeable into or exercisable for, or giving any Person a right to subscribe
for or acquire, any securities of the Company or any of its Subsidiaries, and no
securities or obligations evidencing such rights are authorized, issued or
outstanding. Except for the Convertible Notes, the Company does not have
outstanding any bonds, debentures, notes or other obligations the holders of
which have the right to vote (or, except as referred to in this subsection (b),
convertible into or exercisable for securities having the right to vote) with
the stockholders of the Company on any matter ("Voting Debt").
 
     (c) Corporate Authority; Approval and Fairness.  (i) The Company has all
requisite corporate power and authority and has taken all corporate action
necessary in order to execute, deliver and perform its obligations under this
Agreement and the Stock Option Agreement and to consummate, subject only to
approval of the Merger by the holders of at least a majority of the outstanding
Common Shares voting separately as a class (the "Company Common Stock Requisite
Vote") and a majority of the outstanding Preferred Shares voting separately as a
class (the "Company Preferred Stock Requisite Vote" and, together with the
Company Common Stock Requisite Vote, the "Company Requisite Vote"), the Merger.
This Agreement and the Stock Option Agreement are the valid and binding
agreements of the Company enforceable against the Company in accordance with
their terms, subject to bankruptcy, insolvency, fraudulent transfer,
reorganization, moratorium and similar laws of general applicability relating to
or affecting creditors' rights and to general equity principles (the "Bankruptcy
and Equity Exception").
 
     (ii) The board of directors of the Company (A) has unanimously declared
that the Agreement, the Stock Option Agreement, the Merger and the other
transactions contemplated hereby and thereby are advisable and in the best
interests of the Company, (B) has authorized, approved and adopted in all
respects the Agreement, the Stock Option Agreement, the Merger and the other
transactions contemplated hereby and thereby, and (C) has received the opinion
of its financial advisors, Salomon Smith Barney, to the effect that the
consideration to be received by the holders of the Shares in the Merger is fair
from a financial point of view to such holders.

Improvements Act of 1976, as amended (the "HSR Act"), the Securities Exchange

and such notices and consents as may be required under the antitrust
notification insurance laws of any state in which the Company, Parent or any of
their respective subsidiaries is domiciled or does business, no notices, reports

obtained by the Company from, any governmental or regulatory authority, agency,
commission, body or other governmental entity ("Governmental Entity"), in
connection with the execution and delivery of this Agreement and the Stock
Option Agreement by the Company and the consummation by the Company of the
Merger and the other transactions contemplated hereby and thereby, except those
that the failure to make or obtain are not, individually or in the aggregate,
reasonably likely to have a Company Material Adverse Effect or prevent,
materially delay or materially impair the ability of the Company to consummate
the transactions contemplated by this Agreement and the Stock Option Agreement.
 
     (ii) The execution, delivery and performance of this Agreement and the
Stock Option Agreement by the Company do not, and the consummation by the
Company of the Merger and the other transactions contemplated hereby and thereby
will not, constitute or result in (A) a breach or violation of, or a default
under, the charter or by-laws of the Company or the comparable governing
instruments of any of its Subsidiaries, (B) a breach or violation of, or a
default under, the acceleration of any obligations or the creation of a lien,
pledge, security interest or other encumbrance on the assets of the Company or
any of its Subsidiaries (with or without notice, lapse of time or both) pursuant
to, any agreement, lease, contract, note, mortgage, indenture, arrangement or
other obligation ("Contracts") binding upon the Company or any of its
Subsidiaries or (provided, as to consummation, the filings and notices are made,
and approvals are obtained, as referred to in Section 5.1(d)(i)), any Law (as
defined in Section 5.1(i)) or governmental or non-governmental permit or license
to which the Company or any of its Subsidiaries is subject or (C) any change in
the rights or obligations of any party under any of the Contracts, except, in
the case of clause (B) or (C) above, for any breach, violation, default,
acceleration, creation or change that, individually or in the aggregate, is not
reasonably likely to have a Company Material Adverse Effect or prevent,
materially delay or materially impair the ability of the Company to consummate
the transactions contemplated by this Agreement or the Stock Option Agreement.
Section 5.1(d) of the Company Disclosure Letter sets forth, to the knowledge of
the executive officers of the Company, a correct and complete list of Contracts
of the Company and its Subsidiaries pursuant to which consents or waivers are or
may be required prior to consummation of the transactions contemplated by this
Agreement and the Stock Option Agreement (whether or not subject to the
exception set forth with respect to clauses (B) and (C) above), except those the
failure to obtain, individually or in the aggregate, is not reasonably likely to
have a Company Material Adverse Effect.
 
     (e) Company Reports; Financial Statements.  (i) The Company has made
available to Parent each registration statement, report, proxy statement or
information statement prepared by it since December 31, 1994 including (i) the
Company's Annual Report on Form 10-K for the year ended December 31, 1996 (the
"Audit Date"), and (ii) the Company's Quarterly Reports on Form 10-Q for the
periods ended March 31, 1997, June 30, 1997 and September 30, 1997, each in the
form (including exhibits, annexes and any amendments thereto) filed with the
Securities and Exchange Commission (the "SEC") (collectively, including any such
reports filed subsequent to the date hereof, the "Company Reports"). As of their
respective dates, the Company Reports did not, and any Company Reports filed
with the SEC subsequent to the date hereof will not, contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements made therein, in light of the
circumstances in which they were made, not misleading. Each of the consolidated
balance sheets included in or incorporated by reference into the Company Reports
(including the related notes and schedules) fairly presents, or will fairly
present, the consolidated financial position of the Company and its Subsidiaries
as of its date and each of the
 
                                       I-9

<PAGE>   99
 
consolidated statements of income and of changes in financial position included
in or incorporated by reference into the Company Reports (including any related
notes and schedules) fairly presents, or will fairly present, the results of
operations, retained earnings and changes in financial position, as the case may
be, of the Company and its Subsidiaries for the periods set forth therein
(subject, in the case of unaudited statements, to notes and normal year-end
audit adjustments that will not be material in amount or effect), in each case
in accordance with generally accepted accounting principles ("GAAP")
consistently applied during the periods involved, except as may be noted
therein.
 
     (ii) The Company has made available to Parent true and complete copies of
the annual and quarterly statements of each of the Company Insurance
Subsidiaries as filed with the applicable insurance regulatory authorities for
the years ended December 31, 1994, 1995 and 1996 and the quarterly periods ended
March 31, 1997, June 30, 1997 and September 30, 1997, including all exhibits,
interrogatories, notes, schedules and any actuarial opinions, affirmations or
certifications or other supporting documents filed in connection therewith
(collectively, the "Company SAP Statements"). The Company SAP Statements were
prepared in conformity with statutory accounting practices prescribed or
permitted by the applicable insurance regulatory authority consistently applied
for the periods covered thereby and present fairly the statutory financial
position of such Company Insurance Subsidiaries as at the respective dates
thereof and the results of operations of such Subsidiaries for the respective
periods then ended. The Company SAP Statements complied in all material respects
with all applicable laws, rules and regulations when filed, and, to the
knowledge of the executive officers of the Company, no material deficiency has
been asserted with respect to any Company SAP Statements by the applicable
insurance regulatory body or any other governmental agency or body. The
statutory balance sheets and income statements included in the Company SAP
Statements have been audited by Price Waterhouse LLP, and the Company has made
available to Parent true and complete copies of all audit opinions related
thereto. The Company has made available to Parent true and complete copies of
all examination reports of insurance departments and any insurance regulatory
agencies since January 1, 1994 relating to the Company Insurance Subsidiaries.
The term "knowledge" when used in this Agreement with respect to the executive
officers of the Company shall mean the actual knowledge, after reasonable
inquiry, of the executive officers of the Company.
 
     (f) Absence of Certain Changes.  Except as disclosed in the Company Reports
filed prior to the date hereof, since the Audit Date the Company and its
Subsidiaries have conducted the businesses of the Company and its Subsidiaries,
taken as a whole, only in, and have not engaged in any material transaction
other than according to, the ordinary and usual course of such businesses and
there has not been (i) any change in the financial condition, management,
properties, prospects, business or results of operations of the Company and its
Subsidiaries or, to the knowledge of the executive officers of the Company, any
development or combination of developments which, individually or in the
aggregate, has had or is reasonably likely to have a Company Material Adverse
Effect; (ii) any material damage, destruction or other casualty loss with
respect to any material asset or property owned, leased or otherwise used by the
Company or any of its Subsidiaries, whether or not covered by insurance; (iii)
any declaration, setting aside or payment of any dividend or other distribution
in respect of the stock of the Company, except for regular quarterly cash
dividends on its Common Shares publicly announced prior to the date hereof and
regular quarterly cash dividends on its Preferred Shares paid in accordance with
the Company's Articles of Incorporation prior to the date hereof; (iv) any
change by the Company in accounting principles, practices or methods other than
those required by GAAP or SAP; (v) any material addition, or any development
involving a prospective material addition, to the Company's consolidated
reserves for future policy benefits or other policy claims and benefits; or (vi)
any material change in the accounting, actuarial, investment, reserving,
underwriting or claims administration policies, practices, procedures, methods,
assumptions or principles of any Company Insurance Subsidiary. Since the Audit
Date, except as provided for herein or as disclosed in the Company Reports filed
prior to the date hereof, there has not been any increase in the compensation
payable or that could become payable by the Company or any of its Subsidiaries
to officers or key employees or any amendment of any of the Compensation and
Benefit Plans (as hereinafter defined) other than increases or amendments in the
ordinary course.

<PAGE>   100
 
     (g) Litigation and Liabilities.  Except as disclosed in the Company Reports
filed prior to the date hereof, there are no (i) civil, criminal or
administrative actions, suits, claims, hearings, investigations or proceedings
pending or, to the knowledge of the executive officers of the Company,
threatened against the Company or any of its Subsidiaries, directors or officers
or (ii) obligations or liabilities of any nature, whether or not accrued,
contingent or otherwise and whether or not required to be disclosed, including
those relating to environmental and occupational safety and health matters, or
any other facts or circumstances of which the executive officers of the Company
have knowledge that could result in any claims against, or obligations or
liabilities of, the Company or any of its affiliates, except for those that are
not, individually or in the aggregate, reasonably likely to have a Company
Material Adverse Effect or prevent or materially burden or materially impair the
ability of the Company to consummate the transactions contemplated by this
Agreement.
 
     (h) Employee Benefits.
 
          (i) A copy of each bonus, deferred compensation, pension, retirement,
     profit-sharing, thrift, savings, employee stock ownership, stock bonus,
     stock purchase, restricted stock, stock option, employment, termination,
     severance, change of control, compensation, medical, health or other plan,
     agreement, policy or arrangement that covers employees, directors, former
     employees or former directors of the Company and its Subsidiaries (the
     "Compensation and Benefit Plans") and any trust agreement or insurance
     contract forming a part of such Compensation and Benefit Plans has been
     made available to Parent prior to the date hereof. The Compensation and
     Benefit Plans are listed in Section 5.1(h) of the Company Disclosure Letter
     and any "change of control" or similar provisions therein are specifically
     identified in Section 5.1(h) of the Company Disclosure Letter.
 
          (ii) All Compensation and Benefit Plans are in substantial compliance
     with all applicable law, including the Code and the Employee Retirement
     Income Security Act of 1974, as amended ("ERISA"). Each Compensation and
     Benefit Plan that is an "employee pension benefit plan" within the meaning
     of Section 3(2) of ERISA (a "Pension Plan") and that is intended to be
     qualified under Section 401(a) of the Code has received a favorable
     determination letter from the Internal Revenue Service (the "IRS") with
     respect to "TRA" (as defined in Section 1 of Rev. Proc. 93-39), and the
     Company is not aware of any circumstances reasonably likely to result in
     revocation of any such favorable determination letter. There is no pending
     or, to the knowledge of the executive officers of the Company, threatened
     material litigation relating to the Compensation and Benefit Plans. Neither
     the Company nor any of its Subsidiaries has engaged in a transaction with
     respect to any Compensation and Benefit Plan that, assuming the taxable
     period of such transaction expired as of the date hereof, would subject the
     Company or any of its Subsidiaries to a material tax or penalty imposed by
     either Section 4975 of the Code or Section 502 of ERISA.
 
          (iii) No liability under Subtitle C or D of Title IV of ERISA has been
     or is expected to be incurred by the Company or any Subsidiary with respect
     to any ongoing, frozen or terminated "single-employer plan", within the
     meaning of Section 4001(a)(5) of ERISA, currently or formerly maintained by
     any of them, or the single-employer plan of any entity which is considered
     one employer with the Company under Section 4001 of ERISA or Section 414 of
     the Code (an "ERISA Affiliate"). The Company and its Subsidiaries have not
     contributed, or been obligated to contribute, to a multiemployer plan under
     Subtitle E of Title IV of ERISA at any time since September 26, 1980. No
     notice of a "reportable event", within the meaning of Section 4043 of ERISA
     for which the 30-day reporting requirement has not been waived, has been
     required to be filed for any Pension Plan or by any ERISA Affiliate within
     the 12-month period ending on the date hereof.
 
          (iv) All contributions required to be made under the terms of any
     Compensation and Benefit Plan as of the date hereof have been timely made
     or have been reflected on the most recent consolidated balance sheet filed
     or incorporated by reference in the Company Reports prior to the date
     hereof. Neither any Pension Plan nor any single-employer plan of an ERISA
     Affiliate has an "accumulated funding deficiency" (whether or not waived)
     within the meaning of Section 412 of the Code or Section 302 of ERISA.
     Neither the Company nor its Subsidiaries has provided, or is required to
     provide, security to any
 
                                      I-11

<PAGE>   101
 
     Pension Plan or to any single-employer plan of an ERISA Affiliate pursuant
     to Section 401(a)(29) of the Code.
 
          (v) Under each Pension Plan which is a single-employer plan, as of the
     last day of the most recent plan year ended prior to the date hereof, the
     actuarially determined present value of all "benefit liabilities", within
     the meaning of Section 4001(a)(16) of ERISA (as determined on the basis of
     the actuarial assumptions contained in the Pension Plan's most recent
     actuarial valuation), did not exceed the then current value of the assets
     of such Pension Plan, and there has been no material change in the
     financial condition of such Pension Plan since the last day of the most
     recent plan year.
 
          (vi) Neither the Company nor its Subsidiaries have any obligations for
     retiree health and life benefits under any Compensation and Benefit Plan,
     except as set forth in the Company Disclosure Letter. The Company or its
     Subsidiaries may amend or terminate any such plan under the terms of such
     plan at any time without incurring any material liability thereunder.
 
          (vii) The consummation of the Merger and the other transactions
     contemplated by this Agreement, either alone or in connection with a
     subsequent termination of employment, will not (x) entitle any employees of
     the Company or its Subsidiaries to severance pay, (y) accelerate the time
     of payment or vesting or trigger any payment of compensation or benefits
     under, increase the amount payable or trigger any other material obligation
     pursuant to, any of the Compensation and Benefit Plans or (z) result in any
     breach or violation of, or a default under, any of the Compensation and
     Benefit Plans.
 
          (viii) All Compensation and Benefit Plans covering current or former
     non-U.S. employees or former employees of the Company and its Subsidiaries
     comply in all material respects with applicable local law. The Company and
     its Subsidiaries have no material unfunded liabilities with respect to any
     Pension Plan that covers such non-U.S. employees.
 
          (ix) No amount that could be received (whether in cash or property or
     the vesting of property) as a result of any of the transactions
     contemplated by this Agreement by any employee, officer, director or
     independent contractor of the Company who is a "disqualified individual"
     (as such term is defined in proposed Treasury Regulation Section 1.280G-1)
     under any employment arrangement would be treated as an "excess parachute
     payment" (as such term is defined in Section 280G(b)(1) of the Code).
     Schedule 5.1(h)(ix) contains a true and complete list of each such
     employment arrangement in existence as of the date hereof. To the extent
     that any employment arrangement set forth on Schedule 5.1(h)(ix) has been
     superseded, the new arrangement is not materially different than the
     superseded arrangement.
 
     (i) Compliance with Laws; Permits.  (i) The business and operations of the
Company and the Company Insurance Subsidiaries have been conducted in compliance
with all applicable statutes and regulations regulating the business of
insurance and all applicable orders and directives of insurance regulatory
authorities and market conduct recommendations resulting from market conduct
examinations of insurance regulatory authorities(collectively, "Insurance
Laws"), except where the failure to so conduct such business and operations is
not, individually or in the aggregate, reasonably likely to have a Company
Material Adverse Effect. Notwithstanding the generality of the foregoing, except
where the failure to do so would not, individually or in the aggregate, be
reasonably likely to have a Company Material Adverse Effect, each Company
Insurance Subsidiary and, to the knowledge of the executive officers of the
Company, its agents have marketed, sold and issued insurance products in
compliance, in all material respects, with Insurance Laws applicable to the
business of such Company Insurance Subsidiary and in the respective
jurisdictions in which such products have been sold, including, without
limitation, in compliance with (i) all applicable prohibitions against
"redlining" or withdrawal of business lines, (ii) all applicable requirements
relating to the disclosure of the nature of insurance products as policies of
insurance and (iii) all applicable requirements relating to insurance product
projections and illustrations. In addition, (i) there is no pending or, to the
knowledge of the executive officers of the Company, threatened charge by any
insurance regulatory authority that any of the Company Insurance Subsidiaries
has violated, nor any pending or, to the knowledge of the executive officers of
the Company, threatened investigation by any insurance regulatory authority with
respect to possible violations of, any applicable Insurance Laws where such
violations are, individually or in the
 
                                      I-12

<PAGE>   102
 
aggregate, reasonably likely to have a Company Material Adverse Effect; (ii)
none of the Company Insurance Subsidiaries is subject to any order or decree of
any insurance regulatory authority relating specifically to such Company
Insurance Subsidiary (as opposed to insurance companies generally) which is,
individually or in the aggregate, reasonably likely to have a Company Material
Adverse Effect; and (iii) the Company Insurance Subsidiaries have filed all
reports required to be filed with any insurance regulatory authority on or
before the date hereof as to which the failure to file such reports is,
individually or in the aggregate, reasonably likely to have a Company Material
Adverse Effect.
 
     In addition to Insurance Laws, except as set forth in the Company Reports
filed prior to the date hereof, the businesses of each of the Company and its
Subsidiaries have not been, and are not being, conducted in violation of any
federal, state, local or foreign law, statute, ordinance, rule, regulation,
judgment, order, injunction, decree, arbitration award, agency requirement,
license or permit of any Governmental Entity (collectively with Insurance Laws,
"Laws"), except for violations or possible violations that are not, individually
or in the aggregate, reasonably likely to have a Company Material Adverse Effect
or prevent or materially burden or materially impair the ability of the Company
to consummate the transactions contemplated by this Agreement. Except as set
forth in the Company Reports filed prior to the date hereof, no investigation or
review by any Governmental Entity with respect to the Company or any of its
Subsidiaries is pending or, to the knowledge of the executive officers of the
Company, threatened, nor, to the knowledge of the executive officers of the
Company, has any Governmental Entity indicated an intention to conduct the same,
except for those the outcome of which are not, individually or in the aggregate,
reasonably likely to have a Company Material Adverse Effect or prevent or
materially burden or materially impair the ability of the Company to consummate
the transactions contemplated by this Agreement. To the knowledge of the
executive officers of the Company, no material change is required in the
Company's or any of its Subsidiaries' processes, properties or procedures in
connection with any such Laws, and the Company has not received any notice or
communication of any material noncompliance with any such Laws that has not been
cured as of the date hereof. The Company and its Subsidiaries each has all
permits, licenses, trademarks, patents, trade names, copyrights, service marks,
franchises, variances, exemptions, orders and other governmental authorizations,
consents and approvals necessary to conduct its business as presently conducted
except those the absence of which are not, individually or in the aggregate,
reasonably likely to have a Company Material Adverse Effect or prevent or
materially burden or materially impair the ability of the Company to consummate
the Merger and the other transactions contemplated by this Agreement, the Stock
Option Agreement or the Voting Agreement.
 
     (j) Takeover Statutes.  Prior to entering into this Agreement and the Stock
Option Agreement, the Company has taken all actions necessary such that no
restrictive provision of any "fair price," "moratorium," "control share
acquisition," "interested shareholder" or other similar anti-takeover statute or
regulation (including, without limitation, Sections 607.0901 and 607.0902 of the
FBCA) (each a "Takeover Statute") or restrictive provision of any applicable
anti-takeover provision in the charter or by-laws of the Company (including
Article VIII of the Company's Third Amended and Restated Articles of
Incorporation) is, or at the Effective Time will be, applicable to the Company,
Parent, the Shares, the Merger or any other transaction contemplated by this
Agreement, the Stock Option Agreement or the Voting Agreement.
 
     (k) Environmental Matters.  Except as disclosed in the Company Reports
filed prior to the date hereof and except for such matters as are not,
individually or in the aggregate, reasonably likely to have a Company Material
Adverse Effect: (i) the Company and its Subsidiaries have complied with all
applicable Environmental Laws; (ii) the properties currently owned or operated
by the Company (including soils, groundwater, surface water, buildings or other
structures) are not contaminated with any Hazardous Substances; (iii) the
properties formerly owned or operated by the Company or any of its Subsidiaries
were not contaminated with Hazardous Substances during the period of ownership
or operation by the Company or any of its Subsidiaries; (iv) neither the Company
nor any of its Subsidiaries is subject to liability for any Hazardous Substance
disposal or contamination on any third party property; (v) neither the Company
nor any of its Subsidiaries has been associated with any release or threat of
release of any Hazardous Substance; (vi) neither the Company nor any of its
Subsidiaries has received any notice, demand, letter, claim or request for
information alleging that the Company or any of its Subsidiaries may be in
violation of or liable under any Environmental Law;
 
                                      I-13

<PAGE>   103
 
(vii) neither the Company nor any of its Subsidiaries is subject to any orders,
decrees, injunctions or other arrangements with any Governmental Entity or is
subject to any indemnity or other agreement with any third party relating to
liability under any Environmental Law or relating to Hazardous Substances; and
(viii) there are no circumstances or conditions involving the Company or any of
its Subsidiaries that could reasonably be expected to result in any claims,
liability, investigations, costs or restrictions on the ownership, use, or
transfer of any property of the Company pursuant to any Environmental Law.
 
     As used herein, the term "Environmental Law" means any federal, state,
local or foreign law, statute, ordinance, regulation, judgment, order, decree,
arbitration award, agency requirement, license, permit, authorization or
opinion, relating to: (A) the protection, investigation or restoration of the
environment, health and safety, or natural resources, (B) the handling, use,

(C) noise, odor, wetlands, pollution, contamination or any injury or threat of

Authority pursuant to any Environmental Law.
 
     (l) Tax Matters.  As of the date hereof, neither the Company nor any of its
Affiliates has taken or agreed to take any action, nor do the executive officers
of the Company have any knowledge of any fact or circumstance, that would
prevent the Merger and the other transactions contemplated by this Agreement
from qualifying as a "reorganization" within the meaning of Section 368(a) of
the Code.

     the fiscal years prior to and including the most recent fiscal year;
 
          (iv) the Company and its Subsidiaries have never been members of any
     consolidated group for income tax purposes other than the consolidated

     and delivery of this Agreement or the performance of its obligations
     hereunder, in violation of any licenses, sublicenses and other agreements
     as to which the Company is a party and pursuant to which the Company is
     authorized to use any third-party patents, trademarks, service marks, and
     copyrights ("Third-Party Intellectual Property Rights");
 
          (B) no claims with respect to (I) the patents, registered and material
     unregistered trademarks and service marks, registered copyrights, trade
     names, and any applications therefor owned by the Company or any its
     Subsidiaries (the "Company Intellectual Property Rights"); (II) any trade
     secret material to the Company; or (III) Third-Party Intellectual Property
     Rights are currently pending or, to the knowledge of the executive officers
     of the Company, are threatened by any Person;
 
          (C) the executive officers of the Company do not know of any valid
     grounds for any bona fide claims (I) to the effect that the sale, licensing
     or use of any product as now used, sold or licensed or proposed for use,
     sale or license by the Company or any of its Subsidiaries, infringes on any
     copyright, patent, trademark, service mark or trade secret; (II) against
     the use by the Company or any of its Subsidiaries, of any trademarks, trade
     names, trade secrets, copyrights, patents, technology, know-how or computer
     software programs and applications used in the business of the Company or
     any of its Subsidiaries as currently conducted or as proposed to be
     conducted; (III) challenging the ownership, validity or effectiveness of
     any of the Company Intellectual Property Rights or other trade secret
     material to the Company; or (IV) challenging the license or legally
     enforceable right to use of the Third-Party Intellectual Rights by the
     Company or any of its Subsidiaries; and
 
          (D) to the knowledge of the executive officers of the Company, there
     is no unauthorized use, infringement or misappropriation of any of the
     Company Intellectual Property Rights by any third party, including any
     employee or former employee of the Company or any of its Subsidiaries.
 
     (p) Material Contracts.  All of the material contracts of the Company and
its Subsidiaries that are required to be described in the Company Reports or to
be filed as exhibits thereto are described in the Company Reports or filed as
exhibits thereto and are in full force and effect. True and complete copies of
all such material contracts have been delivered or have been made available by
the Company to Parent. Neither the Company nor any of its Subsidiaries nor any
other party is in breach of or in default under any such contract except for
such breaches and defaults as are not, individually or in the aggregate,
reasonably likely to have a Company Material Adverse Effect. Neither the Company
nor any of its Subsidiaries is party to any agreement containing any provision
or covenant limiting in any material respect the ability of the Company or any
of its Subsidiaries or, except as specifically identified on Section 5.1(p) of
the Company Disclosure Letter, assuming the consummation of the transactions
contemplated by this Agreement, Parent or any of its Subsidiaries to (A) sell
any products or services of or to any other person, (B) engage in any line of
business or (C) compete with or to obtain products or services from any person
or limiting the ability of any person to provide products or services to the
Company or any of its Subsidiaries.
 
     (q) Rights Plan.  (i) Prior to Parent entering into this Agreement, the
Stock Option Agreement and the Voting Agreement, the Company has taken all
actions necessary such that, for all purposes under the Rights Agreement, Parent
shall not be deemed an Acquiring Person (as defined in the Rights Agreement),
the Distribution Date (as defined in the Rights Agreement) shall not be deemed
to occur and the rights issuable pursuant to the Rights Agreement (the "Rights")
will not separate from the Common Shares, as a result of Parent's entering into
this Agreement, the Stock Option Agreement or the Voting Agreement or
consummating the Merger and/or the other transactions contemplated hereby or
thereby.
 
                                      I-16

<PAGE>   106
 
     (ii) The Company has taken all necessary action with respect to all of the
outstanding Rights so that, as of immediately prior to the Effective Time, (A)
neither the Company nor Parent will have any obligations under the Rights or the
Rights Agreement and (B) the holders of the Rights will have no rights under the
Rights or the Rights Agreement. If requested to do so by Parent, the Company
will take all action as may be necessary to extend the term of the Rights
Agreement beyond March 10, 1998 or (ii) to adopt a new rights agreement (the
"New Rights Agreement") upon expiration of the Rights Agreement which is
identical in all respects to the Rights Agreement, and to provide that the
Rights Agreement or New Rights Agreement shall not expire or terminate prior to
the earlier of the Effective Time and the date that this Agreement is terminated
pursuant to the terms hereof. In the event that the Parent requests the Company
to adopt a New Rights Agreement, the Company will take all action as may be
necessary to ensure that the representations of the Company contained in this
Section 5.1(q) with respect to the Rights Plan are true and correct with respect
to the New Rights Plan as well.
 
     (r) Brokers and Finders.  Neither the Company nor any of its officers,
directors or employees has employed any broker or finder or incurred any
liability for any brokerage fees, commissions or finders, fees in connection
with the Merger or the other transactions contemplated in this Agreement except
that the Company has employed Salomon Smith Barney as its financial advisor, the
arrangements with which have been disclosed to Parent prior to the date hereof.
 
     (s) Insurance Matters.  (i) Except as otherwise are not, individually or in
the aggregate, reasonably likely to have a Company Material Adverse Effect, all
policies, binders, slips, certificates, annuity contracts and participation
agreements and other agreements of insurance, whether individual or group, in
effect as of the date hereof (including all applications, supplements,
endorsements, riders and ancillary agreements in connection therewith) that are
issued by the Company Insurance Subsidiaries (the "Company Insurance Contracts")
and any and all marketing materials, are, to the extent required under
applicable law, on forms approved by applicable insurance regulatory authorities
or which have been filed and not objected to by such authorities within the
period provided for objection, and such forms comply in all material respects
with the insurance statutes, regulations and rules applicable thereto and, as to
premium rates established by the Company or any Company Insurance Subsidiary
which are required to be filed with or approved by insurance regulatory
authorities, the rates have been so filed or approved, the premiums charged
conform thereto in all material respects, and such premiums comply in all
material respects with the insurance statutes, regulations and rules applicable
thereto.
 
     (ii) All reinsurance and coinsurance treaties or agreements, including
retrocessional agreements, to which the Company or any Company Insurance
Subsidiary is a party or under which the Company or any Company Insurance
Subsidiary has any existing rights, obligations or liabilities are in full force
and effect, except for such treaties or agreements the failure to be in full
force and effect of which are not, individually or in the aggregate, reasonably
likely to have a Company Material Adverse Effect. Neither the Company nor any
Company Insurance Subsidiary, nor, to the knowledge of the executive officers of
the Company, any other party to a reinsurance or coinsurance treaty or agreement
to which the Company or any Company Insurance Subsidiary is a party, is in
default in any material respect as to any provision thereof, and no such
agreement contains any provision providing that the other party thereto may
terminate such agreement by reason of the transactions contemplated by this
Agreement. The Company has not received any notice to the effect that the
financial condition of any other party to any such agreement is impaired with
the result that a default thereunder may reasonably be anticipated, whether or
not such default may be cured by the operation of any offset clause in such
agreement. No insurer or reinsurer or group of affiliated insurers or reinsurers
accounted for the direction to the Company and the Company Insurance
Subsidiaries or the ceding by the Company and the Company Insurance Subsidiaries
of insurance or reinsurance business in an aggregate amount equal to two percent
or more of the consolidated gross premium income of the Company and the Company
Insurance Subsidiaries for the year ended December 31, 1996.
 
     (iii) Prior to the date hereof, the Company has delivered or made available
to Parent a true and complete copy of any actuarial reports prepared by
actuaries, independent or otherwise, with respect to the Company or any Company
Insurance Subsidiary since December 31, 1994, and all attachments, addenda,
supplements and modifications thereto (the "Company Actuarial Analyses"). The
information and data
 
                                      I-17

<PAGE>   107
 
furnished by the Company or any Company Insurance Subsidiary to its independent
actuaries in connection with the preparation of the Company Actuarial Analyses
were accurate in all material respects. Furthermore, to the knowledge of the
executive officers of the Company, each Company Actuarial Analysis was based
upon an accurate inventory of policies in force for the Company and the Company
Insurance Subsidiaries, as the case may be, at the relevant time of preparation,
was prepared using appropriate modeling procedures accurately applied and in
conformity with generally accepted actuarial standards consistently applied, and
the projections contained therein were properly prepared in accordance with the
assumptions stated therein.
 
     (iv) None of Standard & Poor's Corporation, Moody's Investors Service, Inc.
or A.M. Best Company has announced that it has under surveillance or review its
rating of the financial strength or claims-paying ability of any Company
Insurance Subsidiary and the Company has no reason to believe that any rating
presently held by the Company Insurance Subsidiaries is likely to be modified,
qualified, lowered or placed under such surveillance for any reason, including
as a result of the transactions contemplated hereby.
 
     (v) Except as would not reasonably be expected to have a Company Material
Adverse Effect, all annuity contracts and life insurance policies issued by each
Company Insurance Subsidiary to an annuityholder domiciled in the United States
meet all definitional or other requirements for qualification under the Code
section applicable (or intended to be applicable) to such annuity contracts or
life insurance policies, including, without limitation, the following: (A) each
life insurance policy meets the requirements of sections 101(f), 817(h) or 7702
of the Code, as applicable; (B) no life insurance contract issued by any Company
Insurance Company is a "modified endowment contract" within the meaning of
section 7702A of the Code unless and to the extent that the holders of the
policies have been notified of their classification; (C) each annuity contract
issued, entered into or sold by any Company Insurance Subsidiary qualifies as an
annuity under federal tax law; (D) each annuity contract meets the requirements
of, and has been administered consistent with section 817(h) and 72 of the Code
including but not limited to section 72(s) of the Code (except for those
contracts specifically excluded from such requirement pursuant to section
72(s)(5) of the Code); (E) each annuity contract intended to qualify under
sections 130, 403(a), 403(b) or 408(b) of the Code contains all provisions
required for qualification under such sections of the Code; (F) each annuity
contract marketed as, or in connection with, plans that are intended to qualify
under section 401, 403, 408 or 457 of the Code complies with the requirements of
such section; and (G) none of the Company Insurance Subsidiaries have entered
into any agreement or are involved in any discussions or negotiations and there
are no audits, examinations, investigations or other proceedings with the IRS
with respect to the failure of any life insurance policy under section 7702 or
817(h) of the Code or the failure of any annuity contract to meet the
requirements of section 72(s) of the Code. There are no "hold harmless"
indemnification agreements respecting the tax qualification or treatment of any
product or plan sold, issued, entered into or administered by the Company
Insurance Subsidiaries, and there have been no claims asserted by any Person
under such "hold harmless" indemnification agreements so set forth.
 
     (t) Liabilities and Reserves.  (i) The reserves carried on the Company SAP
Statements of each Company Insurance Subsidiary for future insurance policy
benefits, losses, claims and similar purposes were, as of the respective dates
of such Company SAP Statements, in compliance in all material respects with the
requirements for reserves established by the insurance departments of the state
of domicile of such Company Insurance Subsidiary, were determined in all
material respects in accordance with generally accepted actuarial standards and
principles consistently applied, and were fairly stated in all material respects
in accordance with sound actuarial and statutory accounting principles. Such
reserves were adequate in the aggregate to cover the total amount of all
reasonably anticipated liabilities of the Company and each Company Insurance
Subsidiary under all outstanding insurance, reinsurance and other applicable
agreements as of the respective dates of such Company SAP Statements. The
admitted assets of each Company Insurance Subsidiary as determined under
applicable Laws are in an amount at least equal to the minimum amounts required
by applicable Laws. In addition, the Company has delivered or made available to
Parent copies of all work papers used as the basis for establishing the reserves
for the Company and the Company Insurance Subsidiaries at December 31, 1995 and
December 31, 1996, respectively.
 
     (ii) Except for regular periodic assessments in the ordinary course of
business or assessments based on developments which are publicly known within
the insurance industry, to the knowledge of the executive
 
                                      I-18

<PAGE>   108
 
officers of the Company, no claim or assessment is pending or threatened against
any Company Insurance Subsidiary which is peculiar or unique to such Company
Insurance Subsidiary by any state insurance guaranty associations in connection
with such association's fund relating to insolvent insurers which if determined
adversely, would, individually or in the aggregate, be reasonably likely to have
a Company Material Adverse Effect.
 
     (u) Investment Company.  None of the Company Insurance Subsidiaries
maintains any separate accounts. Neither the Company nor any of its Subsidiaries
conducts activities of or is otherwise deemed under applicable law to control an
"investment advisor" as such term is defined in Section 2(a)(20) of the 1940
Act, whether or not registered under the Investment Advisers Act of 1940, as
amended. Neither the Company nor any of its Subsidiaries is an "investment
company" as defined under the 1940 Act, and neither the Company nor any of its
Subsidiaries sponsors any Person that is such an investment company.
 
     5.2.  Representations and Warranties of Parent and Merger
Subsidiary.  Except as set forth in the corresponding sections or subsections of
the disclosure letter delivered to the Company by Parent on or prior to entering
into this Agreement (the "Parent Disclosure Letter") or in any Parent Report (as
hereinafter defined) filed prior to the date hereof, Parent and Merger
Subsidiary each hereby represent and warrant to the Company that:
 
     (a) Capitalization of Merger Subsidiary.  The authorized stock of Merger
Subsidiary consists of 1,000 shares of Common Stock, par value $.01 per share,

and at the Effective Time will be, owned by Parent, and there are (i) no other
shares of stock or voting securities of Merger Subsidiary, (ii) no securities of
Merger Subsidiary convertible into or exchangeable for shares of stock or voting

of any nature other than those incident to its formation and pursuant to this
Agreement and the Merger and the other transactions contemplated by this
Agreement.
 
     (b) Organization, Good Standing and Qualification.  (i) Each of Parent and
Merger Subsidiary is a corporation duly organized, validly existing and in good
standing under the laws of its jurisdiction of incorporation and has all
requisite corporate power and authority to own and operate its properties and
assets and to carry on its business as presently conducted and is qualified to
do business and is in good standing as a foreign corporation in each
jurisdiction where the ownership or operation of its properties or conduct of
its business requires such qualification, except where the failure to be so
qualified or in such good standing, is not reasonably likely, individually or in
the aggregate, to have a Parent Material Adverse Effect (as defined below).
Parent has made available to the Company a complete and correct copy of Parent's
and Merger Subsidiary's charter and by-laws, each as amended to the date hereof.
Parent's and Merger Subsidiary's charter and by-laws so delivered are in full

shares of Serial Preferred Stock, par value $5.00 per share, none of which was
outstanding as of the close of business on December 21, 1997. All of the
outstanding shares of Parent Common Stock are duly authorized, validly issued,
fully paid and nonassessable.
 
     (d) Corporate Authority.

Merger Subsidiary, enforceable against each of Parent and Merger Subsidiary in
accordance with its terms, subject to the Bankruptcy and Equity Exception.
 
     (ii) Prior to the Effective Time, Parent will have taken all necessary
action to permit it to issue the number of shares of Parent Common Stock and
Parent Preferred Stock required to be issued pursuant to Article IV. The Parent
Common Stock and Parent Preferred Stock, when issued, will be duly authorized,
validly issued, fully paid and nonassessable, and no stockholder of Parent will
have any preemptive right of subscription or purchase in respect thereof. The
Parent Common Stock and Parent Preferred Stock, when issued, will be registered

the Company, Parent or any of their respective subsidiaries is domiciled or does
business, no notices, reports or other filings are required to be made by Parent
or Merger Subsidiary with, nor are any consents, registrations, approvals,

from, any Governmental Entity, in connection with the execution and delivery of
this Agreement by Parent and Merger Subsidiary and the consummation by Parent
and Merger Subsidiary of the Merger and the other transactions contemplated
hereby, except those that the failure to make or obtain are not, individually or
in the aggregate, reasonably likely to have a Parent Material Adverse Effect or
prevent, materially delay or materially impair the ability of Parent or Merger
Subsidiary to consummate the transactions contemplated by this Agreement.
 
     (ii) The execution, delivery and performance of this Agreement by Parent
and Merger Subsidiary do not, and the consummation by Parent and Merger
Subsidiary of the Merger and the other transactions contemplated hereby will
not, constitute or result in (A) a breach or violation of, or a default under,
the certificate or by-laws of Parent and Merger Subsidiary or the comparable
governing instruments of any of its Subsidiaries, (B) a breach or violation of,
or a default under, the acceleration of any obligations or the creation of a
lien, pledge, security interest or other encumbrance on the assets of Parent or
any of its Subsidiaries (with or without notice, lapse of time or both) pursuant
to, any Contracts binding upon Parent or any of its Subsidiaries or (provided,
as to consummation, the filings and notices are made, and approvals are
obtained, as referred to in Section 5.2(e)(i)) or any Law or governmental or
non-governmental permit or license to which Parent or any of its Subsidiaries is
subject or (C) any change in the rights or obligations of any party under any of
the Contracts, except, in the case of clause (B) or (C) above, for breach,
violation, default, acceleration, creation or change that is not, individually
or in the aggregate, reasonably likely to have a Parent Material Adverse Effect
or prevent, materially delay or materially impair the ability of Parent or
Merger Subsidiary to consummate the transactions contemplated by this Agreement.
 
     (f) Parent Reports; Financial Statements.  Parent has made available to the
Company each report or proxy statement prepared by it since December 31, 1994,
including (i) Parent's Annual Report on Form 10-K for the year ended December
31, 1996 (the "Parent Audit Date"), and (ii) Parent's Quarterly Reports on Form
10-Q for the periods ended March 31, 1997, June 30, 1996 and September 30, 1997,
each in the form (including exhibits, annexes and any amendments thereto) filed
with the SEC (collectively, including any such reports filed subsequent to the
date hereof, the "Parent Reports"). As of their respective dates, the Parent
Reports did not, and any Parent Reports filed with the SEC subsequent to the
date hereof will not, contain any untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements made therein, in light of the circumstances in which they were made,
not misleading. Each of the consolidated balance sheets included in or
incorporated by reference into the Parent Reports (including the related notes
and schedules) fairly presents, or will fairly present, the consolidated
financial position of Parent and its Subsidiaries as of its date and each of the
consolidated statements of income and of changes in financial position included
in or incorporated by reference into the Parent Reports
 
                                      I-20

<PAGE>   110
 
(including any related notes and schedules) fairly presents, or will fairly
present, the results of operations, retained earnings and changes in financial
position, as the case may be, of Parent and its Subsidiaries for the periods set
forth therein (subject, in the case of unaudited statements, to notes and normal
year-end audit adjustments that will not be material in amount or effect), in
each case in accordance with GAAP consistently applied during the periods
involved, except as may be noted therein.
 
     (ii) The annual and quarterly statements of each Subsidiary through which
Parent conducts its insurance operations (the "Parent Insurance Subsidiaries")
as filed with the applicable insurance regulatory authorities for the years
ended December 31, 1994, 1995 and 1996 and the quarterly periods ended March 31,
1997, June 30, 1997 and September 30, 1997, including all exhibits,
interrogatories, notes, schedules and any actuarial opinions, affirmations or
certifications or other supporting documents filed in connection therewith
(collectively, the "Parent SAP Statements") were prepared in conformity with
statutory accounting practices prescribed or permitted by the applicable
insurance regulatory authority consistently applied for the periods covered
thereby and present fairly the statutory financial position of such Parent
Insurance Subsidiaries as at the respective dates thereof and the results of
operations of such Subsidiaries for the respective periods then ended. The
Parent SAP Statements complied in all material respects with all applicable
laws, rules and regulations when filed, and no deficiency that is material to
Parent and its Subsidiaries, taken as a whole, has been asserted with respect to
any Parent SAP Statements by the applicable insurance regulatory body or any
other governmental agency or body.
 
     (g) Absence of Certain Changes.  Except as disclosed in the Parent Reports
filed prior to the date hereof, since the Parent Audit Date Parent and its
Subsidiaries have conducted the business of Parent and its Subsidiaries, taken
as a whole, only in, and have not engaged in any transaction material to the
Company and its Subsidiaries, taken as a whole, other than according to, the
ordinary and usual course of such businesses and there has not been (i) any
change in the financial condition, management, properties, prospects, business
or results of operations of Parent and its Subsidiaries or any development or
combination of developments of which management of Parent has knowledge that,
individually or in the aggregate, is reasonably likely to have a Parent Material
Adverse Effect; (ii) any material damage, destruction or other casualty loss
with respect to any material asset or property owned, leased or otherwise used
by Parent or any of its Subsidiaries, whether or not covered by insurance that,
individually or in the aggregate, is reasonably likely to have a Parent Material
Adverse Affect; (iii) any declaration, setting aside or payment of any dividend
or other distribution in respect of the capital stock of Parent, except for
dividends or other distributions on its capital stock publicly announced prior
to the date hereof or declared and paid consistent with past practice (including
customary increases); or (iv) any material addition, or any development
involving a prospective material addition, to Parent's consolidated reserves for
future policy benefits.
 
     (h) Tax Matters.  As of the date hereof, neither Parent nor any of its
Affiliates has taken or agreed to take any action, nor do the officers of Parent
have any knowledge of any fact or circumstance, that would prevent the Merger
and the other transactions contemplated by this Agreement from qualifying as a
"reorganization" within the meaning of Section 368(a) of the Code.
 
     (i) Brokers and Finders.  Neither Parent nor any of its officers, directors
or employees has employed any broker or finder or incurred any liability for any
brokerage fees, commissions or finders, fees in connection with the Merger or
the other transactions contemplated by this Agreement, except that Parent has
employed Goldman, Sachs & Co. and Barclays as its financial advisors.
 
     (j) Corporate Headquarters.  It is the intention of Parent that the
corporate headquarters of the Surviving Corporation shall remain in the State of
Florida.
 
     (k) Insurance Matters.  The business and operations of the Parent Insurance
Subsidiaries have been conducted in compliance with all Insurance Laws, except
where the failure to so conduct such business and operations is not,
individually or in the aggregate, reasonably likely to have a Parent Material
Adverse Effect. Notwithstanding the generality of the foregoing, except where
the failure to do so would not, individually or in the aggregate, be reasonably
likely to have a Parent Material Adverse Effect, each Parent Insurance
Subsidiary and, to the knowledge of Parent's executive officers, its agents have
marketed, sold and issued insurance products in compliance, in all material
respects, with Insurance Laws applicable to the business of
 
                                      I-21

<PAGE>   111
 
such Parent Insurance Subsidiary and in the respective jurisdictions in which
such products have been sold, including, without limitation, in compliance with
(i) all prohibitions against "redlining" or withdrawal of business lines, (ii)
all applicable requirements relating to the disclosure of the nature of
insurance products as policies of insurance and (iii) all applicable
requirements relating to insurance product projections and illustrations. In
addition, (i) there is no pending or, to the knowledge of the executive officers
of Parent, threatened charge by any insurance regulatory authority that any of
the Parent Insurance Subsidiaries has violated, nor any pending or, to the
knowledge of the executive officers of the Parent, threatened investigation by
any insurance regulatory authority with respect to possible violations of, any
applicable Insurance Laws where such violations are, individually or in the
aggregate, reasonably likely to have a Parent Material Adverse Effect; (ii) none
of the Parent Insurance Subsidiaries is subject to any order or decree of any
insurance regulatory authority relating specifically to such Parent Insurance
Subsidiary (as opposed to insurance companies generally) which is, individually
or in the aggregate, reasonably likely to have a Parent Material Adverse Effect;
and (iii) the Parent Insurance Subsidiaries have filed all reports required to
be filed with any insurance regulatory authority on or before the date hereof as
to which failure to file such reports is, individually or in the aggregate,
reasonably likely to have a Parent Material Adverse Effect.
 
     Except as otherwise are not, individually or in the aggregate, reasonably
likely to have a Parent Material Adverse Effect, all policies, binders, slips,
certificates, annuity contracts and participation agreements and other
agreements of insurance, whether individual or group, in effect as of the date
hereof (including all applications, supplements, endorsements, riders and
ancillary agreements in connection therewith) that are issued by the Parent
Insurance Subsidiaries and any and all marketing materials, are, to the extent
required under applicable law, on forms approved by applicable insurance
regulatory authorities or which have been filed and not objected to by such
authorities within the period provided for objection, and such forms comply in
all material respects with the insurance statutes, regulations and rules
applicable thereto and, as to premium rates established by Parent or the Parent
Insurance Subsidiaries which are required to be filed with or approved by
insurance regulatory authorities, the rates have been so filed or approved, the
premiums charged conform thereto in all material respects, and such premiums
comply in all material respects with the insurance statutes, regulations and
rules applicable thereto.

                                   COVENANTS
 
     6.1.  Interim Operations.  The Company covenants and agrees as to itself
and its Subsidiaries that, after the date hereof and prior to the Effective Time
(unless Parent shall otherwise approve in writing, and except as otherwise
expressly contemplated by this Agreement or the Stock Option Agreement or set
forth in Section 6.1 of the Company Disclosure Schedule):

          (l) neither it nor any of its Subsidiaries will authorize or enter
     into an agreement to do any of the foregoing.
 
     6.2.  Acquisition Proposals.  The Company will not, and will not permit or
cause any of its Subsidiaries or any of the officers and directors of it or its
Subsidiaries to, and shall direct its and its Subsidiaries' employees, agents
and representatives (including any investment banker, attorney or accountant
retained by it or any of its Subsidiaries) not to, directly or indirectly,
initiate, solicit, encourage or otherwise facilitate any inquiries or the making
of any proposal or offer with respect to a merger, reorganization, share
exchange, consolidation or similar transaction involving, or any purchase of 15%
or more of the assets or any equity securities of, the Company or any of its
Subsidiaries (any such proposal or offer being hereinafter referred to as an
"Acquisition Proposal"). The Company will not, and will not permit or cause any
of its Subsidiaries or any of the officers and directors of it or its
Subsidiaries to and shall direct its and its Subsidiaries' employees, agents and
representatives (including any investment banker, attorney or accountant
retained by it or any of its Subsidiaries) not to, directly or indirectly,
engage in any negotiations concerning, or provide any confidential information
or data to, or have any discussions with, any Person relating to an Acquisition
Proposal, whether made before or after the date of this Agreement, or otherwise
facilitate any effort or attempt to make or implement an Acquisition Proposal
(including, without limitation, by means of an amendment to the Rights
Agreement); provided, however, that nothing contained in this Agreement shall
prevent the Company or its Board of Directors from (i) complying with Rule 14e-2
promulgated under the Exchange Act with regard to an Acquisition Proposal or
(ii) at any time after 120 days from the date hereof if the Merger shall not by
such date have been approved by the Company Requisite Vote (A) providing
information in response to a request therefor by a Person who has made an
unsolicited bona fide written Acquisition Proposal if the Board of Directors
receives from the Person so requesting such information an executed
confidentiality agreement on terms substantially equivalent to those contained
in the Confidentiality Agreement (as defined in Section 9.7); (B) engaging in
any negotiations or discussions with any Person who has made an unsolicited bona
fide written Acquisition Proposal; or (C) recommending such an Acquisition
Proposal to the stockholders of the Company, if and only to the extent that, (i)
in each such case referred to in clause (A), (B) or (C) above, the Board of
Directors of the Company determines in good faith after consultation with
outside legal counsel that such action is necessary in order for its directors
to comply with their respective fiduciary duties under applicable law and (ii)
in each case referred to in clause (B) or (C) above, the Board of Directors of
the Company determines in good faith (after consultation with its financial
advisor) that such Acquisition Proposal, if accepted, is reasonably likely to be
consummated, taking into account all legal, financial and regulatory aspects of
the proposal and the Person making the proposal and would, if consummated,
result in a more favorable transaction than the transaction contemplated by this
Agreement, taking into account the long-term prospects and interests of the
Company and its stockholders (any such more favorable Acquisition Proposal being
referred to in this Agreement as a "Superior Proposal"). The Company will
immediately cease and cause to be terminated any existing activities,
discussions or negotiations with any parties conducted heretofore with respect
to any of the foregoing. The Company agrees that it will take the necessary
steps to promptly inform the individuals or entities referred to in the first
sentence hereof of the obligations undertaken in this Section 6.2 and in the
Confidentiality Agreement (as defined in Section 9.7). The Company will notify
Parent immediately if any such inquiries, proposals or offers are received by,
any such information is requested from, or any such discussions or negotiations
are sought to be initiated or continued with, any of its representatives
indicating, in connection with such notice, the name of such Person and the
material terms and conditions of any proposals or offers and thereafter shall
keep Parent informed, on a current basis, on the status and terms of any such
proposals or offers and the status of any such negotiations or discussions. The
Company also will promptly request each Person that has heretofore executed a
confidentiality agreement in connection with its consideration of an Acquisition
Proposal to return all confidential information heretofore furnished to such
Person by or on behalf of it or any of its Subsidiaries.
 
     6.3.  Information Supplied.  The Company and Parent each agrees, as to
itself and its Subsidiaries, that none of the information supplied or to be
supplied by it or its Subsidiaries for inclusion or incorporation by reference
in (i) the Registration Statement on Form S-4 to be filed with the SEC by Parent
in connection with the issuance of shares of Parent Common Stock and Parent
Preferred Stock in the Merger (including the proxy statement and prospectus (the
"Prospectus/ Proxy Statement") constituting a part thereof) (the "S-4
 
                                      I-24

<PAGE>   114
 
Registration Statement") will, at the time the S-4 Registration Statement
becomes effective under the Securities Act, contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading, and (ii) the Prospectus/Proxy Statement
and any amendment or supplement thereto will, at the date of mailing to
stockholders and at the times of the meetings of stockholders of the Company to
be held in connection with the Merger, contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading.
 
     6.4.  Stockholders Meetings.  The Company will take, in accordance with its
charter and by-laws, all action necessary to convene a meeting of holders of
Common Shares (the "Common Stockholders Meeting") and a meeting of holders of
Preferred Shares (the "Preferred Stockholders Meeting" and, together with the
Common Stockholders Meeting, the "Stockholders Meetings") as promptly as
practicable, but in no event more than 45 days, after the S-4 Registration
Statement is declared effective to consider and vote upon the approval of the
Merger. Subject to fiduciary obligations under applicable law, the Company's
board of directors shall recommend such approval, shall not withdraw or modify
such recommendation and shall take all lawful action to solicit such approval.
Without limiting the generality of the foregoing, in the event that the
Company's board of directors withdraws or modifies its recommendation, the
Company nonetheless shall cause the Stockholders Meetings to be convened and a
vote taken with respect to the Merger and the board of directors shall
communicate to the Company's stockholders its basis for such withdrawal or
modification as contemplated by Section 607.1103(2)(a) of the FBCA.
 
     6.5.  Filings; Other Actions; Notification.  (a) Parent and the Company
shall promptly prepare and file with the SEC the Prospectus/Proxy Statement, and
Parent shall prepare and file with the SEC the S-4 Registration Statement as
promptly as practicable. Parent and the Company each shall use all reasonable
efforts to have the S-4 Registration Statement declared effective under the
Securities Act as promptly as practicable after such filing, and promptly
thereafter mail the Prospectus/Proxy Statement to the stockholders of the
Company. Parent shall also use all reasonable efforts to obtain prior to the
effective date of the S-4 Registration Statement all necessary state securities
law or "blue sky" permits and approvals required in connection with the Merger
and to consummate the other transactions contemplated by this Agreement and will
pay all expenses incident thereto.
 
     (b) The Company and Parent shall cooperate with each other and use (and
shall cause their respective Subsidiaries to use) all best efforts (i) to cause
to be done all things, necessary, proper or advisable on its part under this
Agreement and applicable Laws to consummate and make effective the Merger and
the other transactions contemplated by this Agreement as soon as practicable,
including preparing and filing as promptly as practicable all documentation to
effect all necessary notices, reports and other filings, and (ii) to obtain as
promptly as practicable all consents, registrations, approvals, permits and
authorizations necessary or advisable to be obtained from any third party and/or
any Governmental Entity in connection with, as a result of or in order to
consummate the Merger or any of the other transactions contemplated by this
Agreement, including, without limitation, upon request of Parent, all material
consents required in connection with the consummation of the Merger; provided,
however, that nothing in this Section 6.5 shall require, or be construed to
require, Parent, in connection with the receipt of any regulatory approval, to
proffer to, or agree to (i) sell or hold separate and agree to sell or to
discontinue to or limit, before or after the Effective Time, any assets,
businesses, or interest in any assets or businesses of Parent, the Company or
any of their respective Affiliates (or to consent to any sale, or agreement to
sell, or discontinuance or limitation by the Company of any of its assets or
businesses) or (ii) agree to any conditions relating to, or changes or
restriction in, the operations of any such asset or businesses which, in either
case, could, in the judgment of the Board of Parent, materially and adversely
impact the economic or business benefits to Parent of the transactions
contemplated by this Agreement. Subject to applicable laws relating to the
exchange of information, Parent and the Company shall have the right to review
in advance, and to the extent practicable each will consult the other on, all
the information relating to Parent or the Company, as the case may be, and any
of their respective Subsidiaries, that appear in any filing made with, or
written materials submitted to, any third party and/or any Governmental Entity
in connection with the Merger and the other transactions contemplated by this
 
                                      I-25

<PAGE>   115
 
Agreement. In exercising the foregoing right, each of the Company and Parent
shall act reasonably and as promptly as practicable.
 
     (c) The Company and Parent each shall, upon request by the other, furnish
the other with all information concerning itself, its Subsidiaries, directors,
officers and stockholders and such other matters as may be reasonably necessary
or advisable in connection with the Prospectus/Proxy Statement, the S-4
Registration Statement or any other statement, filing, notice or application
made by or on behalf of Parent, the Company or any of their respective
Subsidiaries to any third party and/or any Governmental Entity in connection
with the Merger and the transactions contemplated by this Agreement.
 
     (d) The Company and Parent each shall keep the other apprised of the status
of matters relating to completion of the transactions contemplated hereby,
including promptly furnishing the other with copies of notices or other
communications received by Parent or the Company, as the case may be, or any of
its Subsidiaries, from any third party and/or any Governmental Entity with
respect to the Merger and the other transactions contemplated by this Agreement.
The Company and Parent each shall give prompt notice to the other of any change
that is reasonably likely to result in a Company Material Adverse Effect or
Parent Material Adverse Effect, respectively.
 
     (e) The Company shall use its best efforts to cause the Company and each of
the persons listed in Section 6.5(e) of the Company Disclosure Schedule to enter
into prior to the Effective Time an Amendment of Severance Agreement in the form
attached hereto as Exhibit D or E, as applicable.
 
     6.6.  Taxation.  Subject to Section 6.2, neither Parent nor the Company
shall take or cause to be taken any action, whether before or after the
Effective Time, that would disqualify the Merger as a "reorganization" within
the meaning of Section 368(a) of the Code. Each of Parent and the Company agrees
to use all reasonable efforts to cure any impediment to the qualification of the
Merger as a "reorganization" within the meaning of Section 368(a) of the Code.
 
     6.7.  Access.  (a) Upon reasonable notice, and except as may otherwise be
required by applicable law, the Company shall (and shall cause its Subsidiaries
to) afford Parent's officers, employees, counsel, accountants and other
authorized representatives ("Representatives") access, during normal business
hours throughout the period prior to the Effective Time, to the Company's and
its Subsidiaries' management, properties, books, contracts and records and,
during such period, shall (and shall cause its Subsidiaries to) furnish promptly
to Parent all information concerning the Company's and its Subsidiaries'
business, properties and personnel as may reasonably be requested, provided that
no investigation pursuant to this Section shall affect or be deemed to modify
any representation or warranty made by the Company, and provided, further, that
the foregoing shall not require the Company to permit any inspection, or to
disclose any information, that in the reasonable judgment of the Company would
result in the disclosure of any trade secrets of third parties or violate any of
its obligations with respect to confidentiality if the Company shall have used
all reasonable efforts to obtain the consent of such third party to such
inspection or disclosure. All requests for information made pursuant to this
Section 6.7(a) shall be directed to an executive officer of the Company or such
Person as may be designated by the Company's officers. All such information
shall be governed by the terms of the Confidentiality Agreement (as hereinafter
defined).
 
     (b) Upon reasonable notice, and except as may otherwise be required by
applicable law, Parent shall afford the Company's Representatives such access as
is reasonably requested (giving due consideration to the size and capitalization
of, and availability of public information concerning, Parent and the pricing
and other terms contained in this Agreement), during normal business hours
throughout the period prior to the Effective Time, to a limited number of
Parent's management personnel and all relevant books and records, provided that
no investigation pursuant to this Section shall affect or be deemed to modify
any representation or warranty made by Parent, and provided, further, that the
foregoing shall not require Parent to permit any inspection, or to disclose any
information, that in the reasonable judgment of Parent would result in the
disclosure of any trade secrets of third parties or violate any of its
obligations with respect to confidentiality. All requests for information made
pursuant to this Section 6.7(b) shall be directed to an executive officer of
Parent or such Person as may be designated by Parent's officers. All such
information shall be governed by the terms of the Confidentiality Agreement (as
hereinafter defined).
 
                                      I-26

<PAGE>   116
 
     6.8.  Affiliates.  Prior to the date of the Stockholders Meeting, the
Company shall deliver to Parent a list of names and addresses of those Persons
who will be, in the opinion of the Company, as of the time of the Stockholders
Meeting referred to in Section 6.4, "affiliates" of the Company within the
meaning of Rule 145 under the Securities Act. There shall be added to such list
the names and addresses of any other Person subsequently identified by either
Parent or the Company as a Person who may be deemed to be such an affiliate of
the Company; provided, however, that no such Person identified by Parent shall
be added to the list of affiliates of the Company unless Parent delivers to the
Company, on or before the date of the Stockholders Meetings, an opinion of
counsel reasonably satisfactory to the Company to the effect that such Person is
such an affiliate. The Company shall exercise its reasonable best efforts to
deliver or cause to be delivered to Parent, prior to the date of the
Stockholders Meetings, from each affiliate of the Company identified in the
foregoing list (as the same may be supplemented as aforesaid), a letter dated as
of the Stockholders Meetings substantially in the form attached as Exhibit C
(the "Affiliates Letter"). Parent shall not be required to maintain the
effectiveness of the S-4 Registration Statement or any other registration
statement under the Securities Act for the purposes of resale of Parent Common
Stock or Parent Preferred Stock by such affiliates received in the Merger and
the certificates representing Parent Common Stock and Parent Preferred Stock
received by such affiliates shall bear a customary legend regarding applicable
Securities Act restrictions and the provisions of this Section.
 
     6.9.  Stock Exchange Listing and De-listing.  Parent shall use its
reasonable best efforts to cause (i) the shares of Parent Common Stock to be
issued in the Merger to be approved for listing on the NYSE subject to official
notice of issuance and (ii) the shares of Parent Preferred Stock to be issued in
the Merger to be approved for listing on the NYSE subject to official notice of
issuance, prior to the Closing Date. The Surviving Corporation shall use its
best efforts to cause (i) the Common Shares to be de-listed from the NYSE and
de-registered under the Exchange Act as soon as practicable following the
Effective Time and (ii) the Preferred Shares to be de-listed from the NYSE and
de-registered under the Exchange Act as soon as practicable following the
Effective Time.
 
     6.10.  Publicity.  The initial press release shall be a joint press release
and thereafter the Company and Parent each shall consult with each other prior
to issuing any press releases or otherwise making public announcements with
respect to the Merger and the other transactions contemplated by this Agreement
and prior to making any filings with any third party and/or any Governmental
Entity (including any national securities exchange) with respect thereto, except
as may be required by law or by obligations pursuant to any listing agreement
with or rules of any national securities exchange interdealer quotation service.
 
     6.11.  Benefits.
 
     (a) Stock Options.
 
          (i) At the Effective Time, each Company Option whether vested or
     unvested, shall be deemed to constitute an option to acquire, on the same
     terms and conditions as were applicable under such Company Option, the same
     number of shares of Parent Common Stock as the holder of such Company
     Option would have been entitled to receive pursuant to the Merger had such
     holder exercised such option in full immediately prior to the Effective
     Time and assuming that the Common Stock Merger Consideration consisted
     entirely of Parent Common Stock (rounded down to the nearest whole number),
     at a price per share (rounded up to the nearest whole cent) equal to (y)
     the aggregate exercise price for the Common Shares otherwise purchasable
     pursuant to such Company Option divided by (z) the number of full shares of
     Parent Common Stock deemed purchasable pursuant to such Company Option in
     accordance with the foregoing; provided, however, that in the case of any
     Company Option to which Section 422 of the Code applies, the option price,
     the number of shares purchasable pursuant to such option and the terms and
     conditions of exercise of such option shall be determined in accordance
     with the foregoing, subject to such adjustments as are necessary in order
     to satisfy the requirements of Section 424(a) of the Code; provided,
     further, that to the extent that Common Shares acquired upon exercise of a
     Company Option would be subject to vesting or other restrictions under the
     terms of the relevant Company Stock Plan under which such Company Option
     was issued ("Company Restricted Shares"), the number of shares of Parent
     Common Stock to be issued upon exercise of an assumed
 
                                      I-27

<PAGE>   117
 
     Company Option in accordance with the foregoing that bears the same ratio
     to the total shares of Parent Common Stock deemed purchasable pursuant to
     such assumed Company Option as the number of Company Restricted Shares
     bears to the total number of Company Shares issuable under such Company
     Option shall be subject to the same vesting and other restrictions as would
     be applicable to the Company Restricted Shares. At or prior to the
     Effective Time, the Company shall make all necessary arrangements with
     respect to the Company Stock Plans to permit the assumption of the
     unexercised Company Options by Parent pursuant to this Section.
 
          (ii) Effective at the Effective Time, Parent shall assume each Company
     Option in accordance with the terms of the relevant Company Stock Plan
     under which it was issued and the stock option agreement by which it is
     evidenced. At or prior to the Effective Time, Parent shall take all
     corporate action necessary to reserve for issuance a sufficient number of
     shares of Parent Common Stock for delivery upon exercise of Company Options
     assumed by it in accordance with this Section. As soon as practicable after
     the Effective Time, Parent shall file a registration statement on Form S-3
     or Form S-8, as the case may be (or any successor or other appropriate
     forms), or another appropriate form (or shall cause such Company Option to
     be deemed to be an option issued pursuant to a Parent Stock Plan for which
     shares of Parent Common Stock have previously been registered pursuant to
     an appropriate registration form) with respect to the Parent Common Stock
     subject to such Company Options, and shall use its reasonable best efforts
     to maintain the effectiveness of such registration statements (and maintain
     the current status of the prospectus or prospectuses contained therein) for
     so long as such Company Options remain outstanding.
 
     (b) Employee Benefits.  Parent agrees that, during the period commencing at
the Effective Time and ending on the first anniversary thereof, the employees of
the Company and its Subsidiaries will continue to be provided with benefits
under the Company's and its Subsidiaries' existing employee benefit plans (other
than plans involving the issuance or award of Shares or rights to acquire
Shares) that are no less favorable in the aggregate than those currently
provided by the Company and its Subsidiaries to such employees. Any such
employees will receive credit under any plans of Parent or any of its
Subsidiaries for service with the Company or any of its Subsidiaries or
predecessors (to the extent service with such predecessors was credited under
the Compensation and Benefit Plans disclosed in the Company Disclosure Letter)
prior to the Effective Time for the purpose of determining eligibility and
vesting; and Parent shall cause any and all pre-existing condition limitations
(to the extent such limitations did not apply to a pre-existing condition under
the Compensation and Benefit Plans) and eligibility waiting periods under group
health plans of the Parent or any of its Subsidiaries to be waived with respect
to such participants and their eligible dependents. All discretionary awards and
benefits under any employee benefit plans of Parent or any of its Subsidiaries
shall be subject to the discretion of the persons or committee administering
such plans.
 
     6.12.  Expenses.  The Surviving Corporation shall pay all charges and
expenses, including those of the Exchange Agent, in connection with the
transactions contemplated in Article IV. Except as otherwise provided in Section
8.5(b), whether or not the Merger is consummated, all costs and expenses
incurred in connection with this Agreement and the Merger and the other
transactions contemplated by this Agreement shall be paid by the party incurring
such expense, except that expenses incurred in connection with the filing fee
for the S-4 Registration Statement and printing and mailing the Prospectus/Proxy
Statement and the S-4 Registration Statement shall be shared equally by Parent
and the Company.
 
     6.13.  Indemnification; Directors' and Officers' Insurance.  (a) From and
after the Effective Time, Parent agrees that it will indemnify and hold harmless
each present and former director and officer of the Company, (when acting in
such capacity) determined as of the Effective Time (each, an Indemnified Party
and, collectively, the "Indemnified Parties"), against any costs or expenses
(including reasonable attorneys' fees), judgments, fines, losses, claims,
damages or liabilities (collectively, "Costs") incurred in connection with any
claim, action, suit, proceeding or investigation, whether civil, criminal,
administrative or investigative, arising out of matters existing or occurring at
or prior to the Effective Time, whether asserted or claimed prior to, at or
after the Effective Time, to the fullest extent that the Company would have been
permitted under Florida law and its charter or by-laws in effect on the date
hereof to indemnify such Person (and Parent shall also advance expenses as
incurred to the fullest extent permitted under applicable law provided the
Person to

whom expenses are advanced provides a written affirmation of his or her good
faith belief that the standard of conduct necessary for indemnification has been
met), and an undertaking to repay such advances if it is ultimately determined
that such Person is not entitled to indemnification).
 
     (b) Any Indemnified Party wishing to claim indemnification under paragraph
(a) of this Section 6.13, upon learning of any such claim, action, suit,
proceeding or investigation, shall promptly notify Parent thereof, but the
failure to so notify shall not relieve Parent of any liability it may have to
such Indemnified Party if such failure does not materially prejudice the
indemnifying party. In the event of any such claim, action, suit, proceeding or
investigation (whether arising before or after the Effective Time), (i) Parent
or the Surviving Corporation shall have the right to assume the defense thereof
and Parent shall not be liable to such Indemnified Parties for any legal
expenses of other counsel or any other expenses subsequently incurred by such
Indemnified Parties in connection with the defense thereof, except that if
Parent or the Surviving Corporation elects not to assume such defense or counsel
for the Indemnified Parties advises that there are issues which raise conflicts
of interest between Parent or the Surviving Corporation and the Indemnified
Parties, the Indemnified Parties may retain counsel satisfactory to them, and
Parent or the Surviving Corporation shall pay all reasonable fees and expenses
of such counsel for the Indemnified Parties promptly as statements therefor are
received; provided, however, that Parent shall be obligated pursuant to this
paragraph (b) to pay for only one firm of counsel for all Indemnified Parties in
any jurisdiction unless the use of one counsel for such Indemnified Parties
would present such counsel with a conflict of interest, (ii) the Indemnified
Parties will cooperate in the defense of any such matter and (iii) Parent shall
not be liable for any settlement effected without its prior written consent; and
provided, further, that Parent shall not have any obligation hereunder to any
Indemnified Party if and when a court of competent jurisdiction shall ultimately
determine, and such determination shall have become final, that the
indemnification of such Indemnified Party in the manner contemplated hereby is
prohibited by applicable law.
 
     (c) The Surviving Corporation shall maintain the Company's existing
officers' and directors' liability insurance ("D&O Insurance") or D&O Insurance
that is substantially comparable to the Company's existing D&O Insurance for a
period of two years after the Effective Time so long as the annual premium
therefor is not in excess of 200% of the last annual premium paid prior to the
date hereof (such last annual premium being hereinafter referred to as the
"Current Premium"); provided, however, that if the existing D&O Insurance or
substantially comparable D&O Insurance cannot be acquired during the two-year
period for not in excess of 200% of the Current Premium, then the Surviving
Corporation will obtain as much D&O Insurance as can be obtained for the
remainder of such period for a premium not in excess (on an annualized basis) of
200% of the Current Premium. If the D&O Insurance is terminated prior to the end
of the sixth anniversary of the Effective Time, the Surviving Corporation will
purchase extended reporting coverage under D&O Insurance covering claims made
during the remainder of such period with respect to acts which occurred prior to
the Effective Time.
 
     (d) The provisions of this Section are intended to be for the benefit of,
and shall be enforceable by, each of the Indemnified Parties, their heirs and
their representatives.
 
     6.14.  Convertible Notes.  The Company shall repay, at par, the aggregate
principal amount outstanding under the Convertible Notes and cancel such
Convertible Notes in their entirety if they are outstanding as of the Effective
Time.
 
     6.15.  Other Actions by the Company and Parent.
 
     (a) Rights.  If requested by Parent prior to the Effective Time, the board
of directors of the Company shall take all necessary action to terminate or
redeem all of the outstanding Rights and to terminate the Rights Agreement,
effective immediately prior to the Effective Time.
 
     (b) Takeover Statute.  If any Takeover Statute is or may become applicable
to the Merger or the other transactions contemplated by this Agreement, the
Stock Option Agreement or the Voting Agreement, each of Parent and the Company
and its board of directors shall grant such approvals and take such actions as
are necessary so that such transactions may be consummated as promptly as
practicable on the terms contemplated by this Agreement, the Stock Option
Agreement or the Voting Agreement, as the case may be,
 
                                      I-29

or by the Merger and otherwise act to eliminate or minimize the effects of such
statute or regulation on such transactions.
 
     (c) Dividends.  The Company shall coordinate with Parent the declaration,
setting of record dates and payment dates of dividends on Common Shares and
Preferred Shares so that holders of Common Shares and Preferred Shares do not
receive dividends on (i) both Common Shares and Parent Common Stock received in
the Merger or (ii) both Preferred Shares and Parent Preferred Stock received in
the Merger in respect of any calendar quarter or portion thereof or fail to
receive a dividend on (i) either Common Shares or Parent Common Stock received
in the Merger or on (ii) either Preferred Shares or Parent Preferred Stock
received in the Merger in respect of any calendar quarter.

     (d) Tax Opinion.  Parent shall have received, prior to the effective date

likely to have a Parent Material Adverse Effect, and the Company shall have

(v) by action of the Board of Directors of either Parent or the Company if any
Order permanently restraining, enjoining or otherwise prohibiting consummation

<PAGE>   122
 
     a binding written agreement concerning a transaction that constitutes a
     Superior Proposal and the Company notifies Parent in writing that it
     intends to enter into such an agreement, attaching the most current version
     of such agreement to such notice, (iv) Parent does not make, prior to the
     later of (x) five business days after receipt of the Company's written
     notification of its intention to enter into a binding agreement for a
     Superior Proposal (the "Alternative Transaction Notice"), or (y) the
     Section 8.3 Termination Date (as hereinafter defined), an offer that the
     Board of Directors of the Company determines, in good faith after
     consultation with its financial advisors, is at least as favorable, as the
     Superior Proposal, taking into account the long term prospects and
     interests of the Company and its stockholders, and (v) the Company prior to
     such termination pays to Parent in immediately available funds the fees
     required to be paid pursuant to Section 8.5. Without limiting the
     generality of the foregoing, the Company agrees and acknowledges (x) that
     it cannot terminate this Agreement pursuant to this Section 8.3(a) in order
     to enter into a binding agreement referred to in clause (iii) above until
     at least the date falling 180 days from the date of this Agreement (the
     "Section 8.3 Termination Date") or, if later, five business days after
     receipt of the Alternative Transaction Notice and (y) to notify Parent
     promptly if its intention to enter into a written agreement referred to in
     its Alternative Transaction Notice shall change at any time after giving
     such notification.
 
          (b) if there has been a material breach by Parent or Merger Subsidiary
     of any representation, warranty, covenant or agreement contained in this
     Agreement that is not curable or, if curable, is not cured within 20 days
     after written notice of such breach is given by the Company to the party
     committing such breach.
 
     8.4.  Termination by Parent.  This Agreement may be terminated and the
Merger may be abandoned at any time prior to the Effective Time, whether before
or after the approval by the stockholders of Parent referred to in Section
7.1(a), by action of the Board of Directors of Parent if (a) the Company enters
into a binding agreement for a Superior Proposal or the Board of Directors of
the Company shall have withdrawn or adversely modified its approval or
recommendation of this Agreement or, after the mailing of the Prospectus/Proxy
Statement, failed to reconfirm its recommendation of this Agreement within ten
business days after a reasonable written request by Parent to do so, or (b)
there has been a material breach by the Company of any representation, warranty,
covenant or agreement contained in this Agreement that is not curable or, if
curable, is not cured within 20 days after written notice of such breach is
given by Parent to the party committing such breach.
 
     8.5.  Effect of Termination and Abandonment.  (a) In the event of
termination of this Agreement and the abandonment of the Merger pursuant to this
Article VIII, this Agreement (other than as set forth in Section 9.1) shall
become void and of no effect with no liability on the part of any party hereto
(or of any of its directors, officers, employees, agents, legal and financial
advisors or other representatives); provided, however, except as otherwise
provided herein, no such termination shall relieve any party hereto of any
liability or damages resulting from any breach of this Agreement.
 
     (b) In the event that this Agreement is terminated (i) by the Company
pursuant to Section 8.2(iv) or Section 8.3(a) or (ii) by Parent pursuant to
Section 8.2(ii) (and prior to, or at the time of the meeting referred to therein
any Person shall have made an Acquisition Proposal to the Company or any of its
Subsidiaries or any of its stockholders or shall have publicly announced an
intention (whether or not conditional) to make an Acquisition Proposal with
respect to the Company or any of its Subsidiaries) or Section 8.4(a), then the

such termination or date of entrance into an agreement concerning a transaction
that constitutes an Acquisition Proposal or such earlier time as required by
this Agreement, pay Parent a termination fee of $66 million payable by wire
transfer of same day funds. The Company acknowledges that the agreements
contained in this Section 8.5(b) are an integral part of the transactions
contemplated by this Agreement, and that, without these agreements, Parent and
Merger Subsidiary would not enter into this Agreement; accordingly, if the
Company fails to promptly pay the amount due pursuant to this Section 8.5(b),
and, in order to obtain such payment, Parent or Merger Subsidiary commences a
suit which results in a judgment against the Company for the fee set forth in
this paragraph (b), the Company shall pay to Parent or Merger Subsidiary its
costs and expenses (including attorneys' fees) in connection with such suit,
together with interest from the date of
 
                                      I-33

<PAGE>   123
 
termination of this Agreement on the amounts owed at the prime rate of The Chase
Manhattan Bank, in effect from time to time during such period plus two percent.
 
     (c) In the event this Agreement is terminated (i) by the Company pursuant
to Section 8.2(iii) or (ii) by Parent pursuant to Section 8.2(ii) and prior to,
or at the time of the meeting referred to therein, no Person shall have made an
Acquisition Proposal to the Company or any of its Subsidiaries or any of its
stockholders or shall have publicly announced an intention (whether or not
conditional) to make an Acquisition Proposal with respect to the Company or any
of its Subsidiaries, then the Company shall promptly, but in no event later than
two business days after Parent shall have requested payment of its charges and
expenses incurred in connection with the transactions contemplated hereby
("Expenses"), pay to Parent the amount of such Expenses up to a maximum of
$5,000,000 and, if within 18 months of such termination, the Company enters into
an agreement concerning a transaction that constitutes an Acquisition Proposal,
the Company at the time of entering into such agreement, shall pay to Parent the
termination fee of $66 million, in each case payable by wire transfer of same
day funds.

provision and (b) the remainder of this Agreement and the application of such
provision to other Persons or circumstances shall not be affected by such

     9.12.  Assignment.  This Agreement shall not be assignable by operation of
law or otherwise; provided, however, that Parent may designate, by written
notice to the Company, another wholly-owned direct or indirect Subsidiary to be
a Constituent Corporation in lieu of Merger Subsidiary, in which event all
references herein to Merger Subsidiary shall be deemed references to such other
Subsidiary, except that all representations and warranties made herein with
respect to Merger Subsidiary as of the date of this Agreement shall be deemed
representations and warranties made with respect to such other Subsidiary as of
the date of such designation.
 
     9.13.  Alternative Transaction Structure.  Notwithstanding anything to the
contrary contained in this Agreement, if the Company Preferred Stock Requisite
Vote is not obtained at the meeting duly convened to consider the Merger or
Parent reasonably determines that the Company Preferred Stock Requisite Vote is
not likely to be obtained pursuant to the Agreement (other than pursuant to this
Section 9.13), Parent shall, subject to the Company Common Stock Requisite Vote
and the other terms and conditions of this Agreement, merge Merger Subsidiary
with and into the Company such that the separate corporate existence of Merger
Subsidiary shall cease and the Company shall continue as the Surviving
Corporation. In connection with the alternative transaction contemplated by the
prior sentence, the Company shall take all actions reasonably requested by
Parent including, without limitation, promptly amending this Agreement, as
Parent may reasonably deem necessary or appropriate, including, if applicable,
to provide that the Preferred Shares shall remain outstanding after the Merger
pursuant to the same terms and conditions as are in effect on the date hereof
(except that the Preferred Shares shall be convertible into Parent Common Stock)
and adding, if

<PAGE>   129
 
                             STOCK OPTION AGREEMENT
 
     STOCK OPTION AGREEMENT, dated as of December 21, 1997 (the "Agreement"),
between AMERICAN INTERNATIONAL GROUP, INC., a Delaware corporation (the
"Grantee"), and AMERICAN BANKERS INSURANCE GROUP, INC., a Florida corporation
(the "Grantor").
 
     WHEREAS, the Grantee, AIGF, INC., a Florida corporation and a wholly owned
subsidiary of the Grantee ("Newco"), and the Grantor are entering into an
Agreement and Plan of Merger, dated as of the date hereof (the "Merger
Agreement"), which provides, among other things, for the merger of the Grantor
with and into Newco (the "Merger");
 
     WHEREAS, as a condition to their willingness to enter into the Merger
Agreement, the Grantee and Newco have requested that the Grantor grant to the
Grantee an option to purchase up to 8,265,626 shares of Common Stock, par value
$1.00 per share, of the Grantor (the "Common Stock"), upon the terms and subject
to the conditions hereof; and
 
     WHEREAS, in order to induce the Grantee and Newco to enter into the Merger
Agreement, the Grantor is willing to grant the Grantee the requested option.
 
     NOW, THEREFORE, in consideration of the premises and the mutual covenants
and agreements set forth herein, the parties hereto agree as follows:
 
     1.  The Option; Exercise; Adjustments; Payment of Spread.  (a)
Contemporaneously herewith the Grantee, Newco and the Grantor are entering into
the Merger Agreement. Subject to the other terms and conditions set forth
herein, the Grantor hereby grants to the Grantee an irrevocable option (the
"Option") to purchase up to 8,265,626 shares of Common Stock (the "Shares") at a
cash purchase price equal to $47.00 per share (the "Purchase Price"). The Option
may be exercised by the Grantee, in whole or in part, at any time, or from time
to time, following the occurrence of one of the events set forth in Section 2(d)
hereof, and prior to the termination of the Option in accordance with the terms
of this Agreement.
 
     (b) In the event the Grantee wishes to exercise the Option, the Grantee
shall send a written notice to the Grantor (the "Stock Exercise Notice")
specifying a date (subject to the HSR Act (as defined below) and applicable
insurance regulatory approvals) not later than 10 business days and not earlier
than three business days following the date such notice is given for the closing
of such purchase. In the event of any change in the number of issued and out
standing shares of Common Stock by reason of any stock dividend, stock split,
split-up, recapitalization, merger or other change in the corporate or capital
structure of the Grantor, the number of Shares subject to this Option and the
purchase price per Share shall be appropriately adjusted to restore the Grantee
to its rights hereunder, including its right to purchase Shares representing
19.9% of the capital stock of the Grantor entitled to vote generally for the
election of the directors of the Grantor which is issued and outstanding
immediately prior to the exercise of the Option at an aggregate purchase price
equal to the Purchase Price multiplied by 8,265,626.
 
     (c) If at any time the Option is then exercisable pursuant to the terms of
Section 1(a) hereof, the Grantee may elect, in lieu of exercising the Option to
purchase Shares provided in Section 1(a) hereof, to send a written notice to the
Grantor (the "Cash Exercise Notice") specifying a date not later than 20
business days and not earlier than 10 business days following the date such
notice is given on which date the Grantor shall pay to the Grantee an amount in
cash equal to the Spread (as hereinafter defined) multiplied by all or such
portion of the Shares subject to the Option as Grantee shall specify. As used
herein "Spread" shall mean the excess, if any, over the Purchase Price of the
higher of (x) if applicable, the high est price per share of Common Stock
(including any brokerage commissions, transfer taxes and soliciting dealers'
fees) paid or proposed to be paid by any person pursuant to one of the
transactions enumerated in Section 2(d) hereof (the "Alternative Purchase
Price") or (y) the closing price of the shares of Common Stock on the NYSE
Composite Tape on the last trading day immediately prior to the date of the Cash
Exercise Notice (the "Closing Price"). If the Alternative Purchase Price
includes any property other than cash, the Alternative Purchase Price shall be
the sum of (i) the fixed cash amount, if any, included in the Alternative
Purchase
 
                                      II-1

<PAGE>   130
 
Price plus (ii) the fair market value of such other property. If such other
property consists of securities with an existing public trading market, the
average of the closing prices (or the average of the closing bid and asked
prices if closing prices are unavailable) for such securities in their principal
public trading market on the five trading days ending five days prior to the
date of the Cash Exercise Notice shall be deemed to equal the fair market value
of such property. If such other property consists of something other than cash
or securities with an existing public trading market and, as of the payment date
for the Spread, agreement on the value of such other property has not been
reached, the Alternative Purchase Price shall be deemed to equal the Closing
Price. Upon exercise of its right to receive cash pursuant to this Section 1(c),
the obligations of the Grantor to deliver Shares pursuant to Section 3 shall be
terminated with respect to such number of Shares for which the Grantee shall
have elected to be paid the Spread.
 
     2.  Conditions to Delivery of Shares.  The Grantor's obligation to deliver
Shares upon exercise of the Option is subject only to the conditions that:
 
          (a) No preliminary or permanent injunction or other order issued by
     any federal or state court of competent jurisdiction in the United States
     prohibiting the delivery of the Shares shall be in effect; and
 
          (b) Any applicable waiting periods under the Hart-Scott-Rodino
     Antitrust Improvements Act of 1976 (the "HSR Act") shall have expired or
     been terminated; and
 
          (c) Any approval required to be obtained prior to the delivery of the
     Shares under the insurance laws of any state or foreign jurisdiction shall
     have been obtained and be in full force and effect; and
 
          (d) (i) any person (other than Grantee or any of its subsidiaries)
     shall have commenced (as such term is defined in Rule 14d-2 under the
     Securities Exchange Act of 1934 (the "Exchange Act") a tender offer, or
     shall have filed a registration statement under the Securities Act of 1933
     (the "Securities Act") with respect to an exchange offer, to purchase any
     shares of Common Stock such that, upon consummation of such offer, such
     person or a "group" (as such term is defined under the Exchange Act) of
     which such person is a member shall have acquired beneficial ownership (as
     such term is defined in rule 13d-3 of the Exchange Act), or the right to
     acquire beneficial ownership, of 15 percent or more of the then outstanding
     Common Stock; (ii) any person (other than Grantee or any of its
     subsidiaries) shall have publicly announced or delivered to Grantor a
     proposal, or disclosed publicly or to Grantor an intention to make a
     proposal, to purchase 15% or more of the assets or any equity securities
     of, or to engage in a merger, reorganization, tender offer, share exchange,
     consolidation or similar transaction involving the Grantor or any of its
     subsidiaries (an "Acquisition Transaction"); (iii) Grantor or any of its
     subsidiaries shall have authorized, recommended, proposed or publicly
     announced an intention to authorize, recommend or propose, or entered into,
     an agreement, including without limitation, an agreement in principle, with
     any person (other than Grantee or any of its subsidiaries) to effect or
     provide for an Acquisition Transition; (iv) any person shall solicit
     proxies or consents or announce a bona fide intention to solicit proxies or
     consents from Grantor's stockholders (x) relating to directors, (y) in
     opposition to the Merger, the Merger Agreement or any related transactions
     or (z) relating to an Acquisition Transaction (other than solicitations of
     stockholders seeking approval of the Merger, the Merger Agreement or any
     related transactions); or (v) any person (other than Grantee or any of its
     subsidiaries) shall have acquired beneficial ownership (as such term is
     defined in Rule 13d-3 under the Exchange Act) or the right to acquire
     beneficial ownership of, or any "group" (as such term is defined under the
     Exchange Act) shall have been formed which beneficially owns or has the
     right to acquire beneficial ownership of, shares of Common Stock (other
     than trust account shares) aggregating 15 percent or more of the then
     outstanding Common Stock. As used in this Agreement, "person" shall have
     the meaning specified in Sections 3(a)(9) and 13(d)(3) of the Exchange Act.
 
     3.  The Closing.  (a) Any closing hereunder shall take place on the date
specified by the Grantee in its Stock Exercise Notice or Cash Exercise Notice,
as the case may be, at 9:00 A.M., local time, at the offices of Sullivan &
Cromwell, 125 Broad Street, New York, New York, or, if the conditions set forth
in Section 2(a), (b) or (c) have not then been satisfied, on the second business
day following the satisfaction of such conditions, or at such other time and
place as the parties hereto may agree (the "Closing Date"). On the Closing Date,
(i) in the event of a closing pursuant to Section 1(b) hereof, the Grantor will
deliver to the
 
                                      II-2

<PAGE>   131
 
Grantee a certificate or certificates, representing the Shares in the
denominations designated by the Grantee in its Stock Exercise Notice and the
Grantee will purchase such Shares from the Grantor at the price per Share equal
to the Purchase Price or (ii) in the event of a closing pursuant to Section 1(c)
hereof, the Grantor will deliver to the Grantee cash in an amount determined
pursuant to Section 1(c) hereof. Any payment made by the Grantee to the Grantor,
or by the Grantor to the Grantee, pursuant to this Agreement shall be made by
certified or official bank check or by wire transfer of federal funds to a bank
designated by the party receiving such funds.
 
     (b) The certificates representing the Shares shall bear an appropriate
legend relating to the fact that such Shares have not been registered under the
Securities Act of 1933, as amended (the "Securities Act").
 
     4.  Representations and Warranties of the Grantor.  The Grantor represents
and warrants to the Grantee that (a) the Grantor is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Florida and has the requisite corporate power and authority to enter into and
perform this Agreement; (b) the execution and delivery of this Agreement by the
Grantor and the con summation by it of the transactions contemplated hereby have

transfer, reorganization, moratorium and similar laws of general applicability
relating to or affecting creditors' rights and to general equity principles; (c)
the Grantor has taken all necessary corporate action to authorize and reserve
the Shares issuable upon exercise of the Option and the Shares, when issued and
delivered by the Grantor upon exercise of the Option and paid for by Grantee as
contemplated hereby, will be duly authorized, validly issued, fully paid and
non-assessable and free of preemptive rights; (d) except as otherwise required
by the HSR Act and applicable insurance laws, the execution and delivery of this
Agreement by the Grantor and the consummation by it of the transactions
contemplated hereby do not require the consent, waiver, approval or
authorization of or any filing with any person or public authority and will not
violate, result in a breach of or the acceleration of any obligation under, or
constitute a default under, any provision of Grantor's charter or by-laws, or
any material indenture, mortgage, lien, lease, agreement, contract, instrument,
order, law, rule, regulation, judgment, ordinance, or decree, or restriction by
which the Grantor or any of its subsidiaries or any of their respective
properties or assets is bound; (e) no "fair price", "moratorium", "control share
acquisition," "interested shareholder" or other form of antitakeover statute or
regulation, including without limitation, Sections 607.0901 or 607.0902 of the
Florida Business Corporation Act, or similar provision contained in the charter
or by-laws of Grantor, including without limitation, Article VIII of Grantor's
Third Amended and Restated Articles of Incorporation, is or shall be applicable
to the acquisition of Shares pursuant to this Agreement; and (f) the Grantor has
taken all corporate action necessary so that any Shares acquired pursuant to
this Agreement shall not be counted for purposes of determining the number of
shares of Common Stock beneficially owned by the Grantee or any of its
Affiliates or Associates (as such terms are defined in the Rights Agreement)
pursuant to the Rights Agreement, as amended and restated on November 14, 1990,
as amended on December 19, 1997, between the Grantor and ChaseMellon Shareholder
Services, LLC (as successor to Manufacturers Hanover Trust Company), as Rights
Agent (the "Rights Agreement").
 
     5.  Representations and Warranties of the Grantee.  The Grantee represents
and warrants to the Grantor that (a) the execution and delivery of this
Agreement by the Grantee and the consummation by it of the transactions
contemplated hereby have been duly authorized by all necessary corporate action
on the part of the Grantee and this Agreement has been duly executed and
delivered by a duly authorized officer of the Grantee and constitutes a valid
and binding obligation of Grantee; and (b) the Grantee is acquiring the Option
and, if and when it exercises the Option, will be acquiring the Shares issuable
upon the exercise thereof for its own account and not with a view to
distribution or resale in any manner which would be in violation of the
Securities Act.
 
     6.  Listing of Shares; Filings; Governmental Consents.  Subject to
applicable law and the rules and regulations of the New York Stock Exchange,
Inc. (the "NYSE"), the Grantor will promptly file an application to list the
Shares on the NYSE and will use its reasonable best efforts to obtain approval
of such listing and to effect all necessary filings by the Grantor under the HSR
Act and the applicable insurance laws
 
                                      II-3

<PAGE>   132
 
of each state and foreign jurisdiction; provided, however, that if the Grantor
is unable to effect such listing on the NYSE by the Closing Date, the Grantor
will nevertheless be obligated to deliver the Shares upon the Closing Date. Each
of the parties hereto will use its reasonable best efforts to obtain consents of
all third parties and governmental authorities, if any, necessary to the
consummation of the transactions contemplated.
 
     7.  Repurchase of Shares.  If by the date that is the first anniversary of
the date the Merger Agreement was terminated pursuant to the terms thereof (the
"Merger Termination Date"), neither the Grantee nor any other Person has
acquired more than fifty percent (excluding the Shares) of the shares of
outstanding Common Stock, then the Grantor has the right to purchase (the
"Repurchase Right") all, but not less than all, of the Shares at the greater of
(i) the Purchase Price or (ii) the average of the last sales prices for shares
of Common Stock on the five trading days ending five days prior to the date the
Grantor gives written notice of its intention to exercise the Repurchase Right.
If the Grantor does not exercise the Repurchase Right within thirty days
following the end of the one year period after the Merger Termination Date, the
Repurchase Right lapses. In the event the Grantor wishes to exercise the
Repurchase Right, the Grantor shall send a written notice to the Grantee
specifying a date (not later than 20 business days and not earlier than 10
business days following the date such notice is given) for the closing of such
purchase.
 
     8.  Sale of Shares.  At any time prior to the first anniversary of the
Merger Termination Date, the Grantee shall have the right to sell (the "Sale
Right") to the Grantor all, but not less than all, of the Shares at the greater
of (i) the Purchase Price, or (ii) the average of the last sales prices for
shares of Common Stock on the five trading days ending five days prior to the
date the Grantee gives written notice of its intention to exercise the Sale
Right. If the Grantee does not exercise the Sale Right prior to the first
anniversary of the Merger Termination Date, the Sale Right terminates. In the
event the Grantee wishes to exercise the Sale Right, the Grantee shall send a
written notice to the Grantor specifying a date not later than 20 business days
and not earlier than 10 business days following the date such notice is given
for the closing of such sale.
 
     9.  Registration Rights.  (a) In the event that the Grantee shall desire to
sell any of the Shares within three years after the purchase of such Shares
pursuant here to, and such sale requires, in the opinion of counsel to the
Grantee, which opinion shall be reasonably satisfactory to the Grantor and its
counsel, registration of such Shares under the Securities Act, the Grantor will
cooperate with the Grantee and any underwriters in registering such Shares for
resale, including, without limitation, promptly filing a registration statement
which complies with the requirements of applicable federal and state securities
laws, and entering into an underwriting agreement with such under writers upon
such terms and conditions as are customarily contained in underwriting
agreements with respect to secondary distributions; provided that the Grantor
shall not be required to have declared effective more than two registration
statements hereunder and shall be entitled to delay the filing or effectiveness
of any registration statement for up to 60 days if the offering would, in the
judgment of the Board of Directors of the Grantor, require premature disclosure
of any material corporate development or material transaction involving the
Grantor or interfere with any previously planned securities offering by the
Company.
 
     (b) If the Common Stock is registered pursuant to the provisions of this
Section 9, the Grantor agrees (i) to furnish copies of the registration
statement and the prospectus relating to the Shares covered thereby in such
numbers as the Grantee may from time to time reasonably request and (ii) if any
event shall occur as a result of which it becomes necessary to amend or
supplement any registration statement or prospectus, to prepare and file under
the applicable securities laws such amendments and supplements as may be
necessary to keep available for at least 45 days a prospectus covering the
Common Stock meeting the requirements of such securities laws, and to furnish
the Grantee such numbers of copies of the registration statement and prospectus
as amended or supplemented as may reasonably be requested. The Grantor shall
bear the cost of the registration, including, but not limited to, all
registration and filing fees, printing expenses, and fees and disbursements of
counsel and accountants for the Grantor, except that the Grantee shall pay the
fees and disbursements of its counsel, and the underwriting fees and selling
commissions applicable to the shares of Common Stock sold by the Grantee. The
Grantor shall indemnify and hold harmless (i) Grantee, its affiliates and its
officers and directors and (ii) each underwriter and each person who controls
any underwriter within the meaning of the Securities Act or the Securities
Exchange Act of 1934, as amended (collectively, the "Underwriters") ((i) and
(ii) being referred to as "Indemnified Parties") against any losses, claims,
 
                                      II-4

<PAGE>   133
 
damages, liabilities or expenses, to which the Indemnified Parties may become
subject, insofar as such losses, claims, damages, liabilities (or actions in
respect thereof) and expenses arise out of or are based upon any untrue
statement or alleged untrue statement of any material fact contained or
incorporated by reference in any registration statement filed pursuant to this
paragraph, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading; provided, however, that the Grantor will
not be liable in any such case to the extent that any such loss, liability,
claim, damage or expense arises out of or is based upon an untrue statement or
alleged untrue statement in or omission or alleged omission from any such
documents in reliance upon and in conformity with written information furnished
to the Grantor by the Indemnified Parties expressly for use or incorporation by
reference therein.
 
     (c) The Grantee and the Underwriters shall indemnify and hold harmless the
Grantor, its affiliates and its officers and directors against any losses,
claims, damages, liabilities or expenses to which the Grantor, its affiliates
and its officers and directors may become subject, insofar as such losses,
claims, damages, liabilities (or actions in respect thereof) and expenses arise
out of or are based upon any untrue statement of any material fact contained or
incorporated by reference in any registration statement filed pursuant to this
paragraph, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, in each case to the extent, but only to
the extent, that such untrue statement or alleged untrue statement or omission
or alleged omission was made in reliance upon and in conformity with written
information furnished to the Grantor by the Grantee or the Underwriters, as
applicable, specifically for use or incorporation by reference therein.
 
     10.  Expenses.  Each party hereto shall pay its own expenses incurred in
connection with this Agreement, except as otherwise specifically provided
herein.
 
     11.  Specific Performance.  The Grantor acknowledges that if the Grantor
fails to perform any of its obligations under this Agreement immediate and
irreparable harm or injury would be caused to the Grantee for which money
damages would not be an adequate remedy. In such event, the Grantor agrees that
the Grantee shall have the right, in addition to any other rights it may have,
to specific performance of this Agreement. Accordingly, if the Grantee should
institute an action or proceeding seeking specific enforcement of the provisions
hereof, the Grantor hereby waives the claim or defense that the Grantee has an
adequate remedy at law and hereby agrees not to assert in any such action or
proceeding the claim or defense that such a remedy at law exists. The Grantor
further agrees to waive any requirements for the securing or posting of any bond
in connection with obtaining any such equitable relief.

hereunder shall be deemed to have been duly given and made if in writing and if

ARISING WITH RESPECT TO THIS AGREEMENT, IT SHALL SUBMIT TO THE
 
                                      II-6

<PAGE>   135
 
JURISDICTION OF THE UNITED STATES DISTRICT COURT FOR THE DISTRICT OF DELAWARE
AND AGREES TO VENUE IN SUCH COURTS. THE GRANTOR HEREBY APPOINTS THE SECRETARY OF
THE GRANTOR AS ITS AGENT FOR SERVICE OF PROCESS FOR PURPOSES OF THE FOREGOING
SENTENCE ONLY.
 
     19.  Termination.  The right to exercise the Option granted pursuant to
this Agreement shall terminate at the earlier of (i) the Effective Time (as
defined in the Merger Agreement); (ii) 90 days after the Merger Termination Date
(the date referred to in clause (ii) being hereinafter referred to as the
"Option Termination Date") and, (iii) 18 months after the date hereof; provided
that, if the Option cannot be exercised or the Shares cannot be delivered to
Grantee upon such exercise because the conditions set forth in Section 2(a), (b)
or (c) hereof have not yet been satisfied, the Option Termination Date shall be
extended until thirty days after such impediment to exercise or delivery has
been removed.
 
     All representations and warranties contained in this Agreement shall
survive delivery of and payment for the Shares.
 
     20.  Profit Limitation.  (a) Notwithstanding any other provision of this
Agreement, in no event shall the Grantee's Total Profit (as hereinafter defined)
exceed $66 million and, if it otherwise would exceed such amount, the Grantee,
at its sole election, shall either (a) deliver to the Grantor for cancellation
Shares previously purchased by Grantee, (b) pay cash or other consideration to
the Grantor or (c) undertake any combination thereof, so that Grantee's Total
Profit shall not exceed $66 million after taking into account the foregoing
actions.
 
     Notwithstanding any other provision of this Agreement, this Option may not
be exercised for a number of Shares as would, as of the date of the Stock
Exercise Notice, result in a Notional Total Profit (as defined below) of more
than $66 million and, if exercise of the Option otherwise would exceed such
amount, the Grantee, at its discretion, may increase the Purchase Price for that
number of Shares set forth in the Stock Exercise Notice so that the Notional
Total Profit shall not exceed $66 million; provided, that nothing in this
sentence shall restrict any exercise of the Option permitted hereby on any
subsequent date at the Purchase Price set forth in Section 1(a) hereof.
 
     As used herein, the term "Total Profit" shall mean the aggregate amount
(before taxes) of the following: (i) the amount of cash received by Grantee
pursuant to Section 8.5 of the Merger Agreement and Section 1(c) hereof, (ii)
(x) the amount received by Grantee pursuant to the Grantor's repurchase of
Shares pursuant to Sections 7 or 8 hereof, less (y) the Grantee's purchase price
for such Shares, and (iii) (x) the net cash amounts received by Grantee pursuant
to the sale of Shares (or any other securities into which such Shares are
converted or exchanged) to any unaffiliated party, less (y) the Grantee's
purchase price for such Shares.
 
     As used herein, the term "Notional Total Profit" with respect to any number
of Shares as to which Grantee may propose to exercise this Option shall be the
Total Profit determined as of the date of the Stock Exercise Notice assuming
that this Option were exercised on such date for such number of Shares and
assuming that such Shares, together with all other Shares held by Grantee and
its affiliates as of such date, were sold for cash at the closing market price
for the Common Stock as of the close of business on the preceding trading day
(less customary brokerage commissions).
 
     21.  Severability.  If any term, provision, covenant or restriction of this
Agreement is held by a court of competent jurisdiction to be invalid, void or
unenforceable, the remainder of the terms, provisions, covenants and
restrictions of this Agreement shall remain in full force and effect and shall
in no way be affected, impaired or invalidated.
 
     22.  Public Announcement.  The Grantee will consult with the Grantor and
the Grantor will consult with the Grantee before issuing any press release with
respect to the initial announcement of this Agreement, the Option or the
transactions contemplated hereby and neither party shall issue any such press
release prior to such consultation except as may be required by law or the
applicable rules and regulations of the NYSE.

                                VOTING AGREEMENT
 
     THIS VOTING AGREEMENT (the "Agreement") is entered into as of December 21,
1997, between the undersigned stock holders (the "Stockholders") of AMERICAN
BANKERS INSURANCE GROUP, INC., a Florida corporation (the "Company"), and
AMERICAN INTERNATIONAL GROUP, INC., a Delaware corporation ("Parent").
 
     WHEREAS, concurrently with the execution and delivery of this Agreement,
AIGF, INC., a Florida corporation and a wholly owned subsidiary of Parent
("Newco"), Parent and the Company have entered into an Agreement and Plan of
Merger dated as of December 21, 1997 (the "Merger Agreement"), providing for the
merger of the Company with and into Newco (the "Merger") pursuant to the terms
and conditions of the Merger Agreement, and setting forth certain
representations, warranties, covenants and agreements of the parties thereto in
connection with the Merger; and
 
     WHEREAS, as an inducement and a condition to Parent entering into the
Merger Agreement, pursuant to which each Stockholder will receive the Common
Stock Merger Consideration (as defined in the Merger Agreement) in exchange for
each share of Common Stock, par value $1.00 per share, of the Company ("Company
Common Stock") owned by such Stockholder, the Stockholders each have agreed to
enter into this Agreement;
 
     NOW, THEREFORE, for good and valuable consideration, the receipt,
sufficiency and adequacy of which is hereby acknowledged, the parties hereto
agree as follows:
 
     1.  Representations of Stockholders.  Each of the Stockholders severally
represents as to himself or herself that such Stockholder:
 
          (a) is the holder in the capacity set forth on Exhibit A hereto of
     that number of shares of Company Common Stock set forth opposite such
     Stockholder's name on Exhibit A (such Stockholder's "Shares");
 
          (b) does not beneficially own (as such term is defined in the
     Securities Exchange Act of 1934, as amended (the "1934 Act")) any shares of
     Company Common Stock other than his or her Shares, but excluding any shares
     of Company Common Stock which such Stockholder has the right to obtain upon
     the exercise of stock options and upon the conversion of Convertible Notes
     (as defined in the Merger Agreement) outstanding on the date hereof except,
     in the case of Mr. Landon for Shares subject to an option granted prior to
     the date hereof to a third party;
 
          (c) has the right, power and authority to execute and deliver this
     Agreement and to perform his obligations under this Agreement, and this
     Agreement has been duly executed and delivered by such Stockholder and
     constitutes a valid and legally binding agreement of such Stockholder,
     enforceable in accordance with its terms, subject to bankruptcy,
     insolvency, fraudulent transfer, reorganization, moratorium and similar
     laws of general applicability relating to or affecting creditors' rights
     and to general equity principles; and such execution, delivery and
     performance by Shareholder of this Agreement will not (i) conflict with,
     require a consent, waiver or approval under, or result in a breach of or
     default under, any of the terms of any contract, commitment or other
     obligation (written or oral) to which such Stockholder is a party or by
     which such Stockholder is bound; (ii) violate any order, writ, injunction
     decree or statute, or any rule or regulation, applicable to Stockholder or
     any of the properties or assets of Stockholder; or (iii) result in the
     creation of, or impose any obligation on such Stockholder to create, any
     lien, charge or other encumbrance of any nature whatsoever upon the Shares;
     and
 
          (d) the Shares are now and will at all times during the term of this
     Agreement be held by such Stockholder, or by a nominee or custodian for the
     account of such Stockholder, free and clear of all pledges, liens, proxies,
     claims, charges, security interests, preemptive rights and any other
     encumbrances whatsoever with respect to the ownership, transfer or voting
     of such Shares; and there are no outstanding options, warrants or rights to
     purchase or acquire, or other agreements relating to, such Shares other
     than this Agreement.
 
                                      III-1

<PAGE>   139
 
The representations and warranties contained herein shall be made as of the date
hereof and as of each date from the date hereof through and including the date
that the Merger is consummated.
 
     2.  Agreement to Vote Shares.  Each of the Stockholders severally agrees to
vote his or her Shares and any New Shares (as defined in Section 7 hereof), and
shall cause any holder of record of his or her Shares or New Shares to vote, (a)
in favor of adoption and approval of the Merger Agreement and the Merger (and
each other action and transaction contemplated by the Merger Agreement and this
Agreement) at every meeting of the stockholders of the Company at which such
matters are considered and at every adjournment thereof and (b) against any
action or proposal that would compete with or could serve to materially
interfere with, delay, discourage, adversely affect or inhibit the timely
consummation of the Merger. Any such vote shall be cast or consent shall be
given in accordance with such procedures relating thereto as shall ensure that
it is duly counted for purposes of determining that a quorum is present and for
purposes of recording the results of such vote or consent. Each Stockholder
severally agrees to deliver to Parent upon request a proxy substantially in the
form attached hereto as Exhibit B, which proxy shall be coupled with an interest
and irrevocable to the extent permitted under Florida law, with the total number
of such Stockholder's Shares and any New Shares correctly indicated thereon.
Each Stockholder also agrees to use his reasonable efforts to take, or cause to
be taken, all action, and do, or cause to be done, all things necessary or
advisable in order to consummate and make effective the transactions
contemplated by this Agreement.
 
     3.  No Voting Trusts.  After the date hereof, the Stockholders severally
agree that they will not, nor will they permit any entity under their control
to, deposit any of their Shares in a voting trust or subject any of their Shares
to any arrangement with respect to the voting of such Shares other than
agreements entered into with Parent or Newco.
 
     4.  No Proxy Solicitations.  Each of the Stockholders severally agrees that
such Stockholder will not, nor will such Stockholder permit any entity under
their control to, (a) solicit proxies or become a "participant" in a
"solicitation" (as such terms are defined in Regulation 14A under the 1934 Act)
in opposition to or competition with the consummation of the Merger or otherwise
encourage or assist any party in taking or planning any action which would
compete with or otherwise could serve to materially interfere with, delay,
discourage, adversely affect or inhibit the timely consummation of the Merger in
accordance with the terms of the Merger Agreement, (b) directly or indirectly
encourage, initiate or cooperate in a stock holders' vote or action by consent
of the Company's stockholders in opposition to or in competition with the
consummation of the Merger, or (c) become a member of a "group" (as such term is
used in Section 13(d) of the 1934 Act) with respect to any voting securities of
the Company for the purpose of opposing or competing with the consummation of
the Merger; provided, that the foregoing shall not restrict any director of the
Company from taking any action such director believes is necessary to satisfy
such director's fiduciary duty to shareholders of the Company.
 
     5.  Transfer and Encumbrance.  On or after the date hereof, each of the
Stockholders severally agrees not to voluntarily transfer, sell, offer, pledge
or otherwise dispose of or encumber ("Transfer") any of his or her Shares or New
Shares prior to the earlier of (a) the effective date of the Merger or (b) the
date this Agreement shall be terminated in accordance with its terms.
Notwithstanding anything to the contrary in this Agreement, (A) Mr. Landon shall
be permitted to Transfer (i) Shares or New Shares Transferred for net after-tax
proceeds of not in excess of $5,000,000, and (ii) Shares or New Shares
Transferred pursuant to any court order or settlement of any legal proceeding
and (B) Mr. Gaston shall be permitted to Transfer Shares or New Shares
Transferred for net after-tax proceeds of not in excess of $2,000,000.
 
     6.  Legend.  As soon as practicable after the execution of this Agreement,
each Stockholder shall surrender to the Company the certificates representing
the Shares in his or her possession (and within 30 days the Shares not in his or
her possession), shall cause the following legend to be placed on the
certificates representing such Shares and shall request that such legend remain
thereon until the earlier of (i) expiration or termination of the Agreement or
(ii) the consummation of the Merger:
 
     "The shares of capital stock represented by this certificate are subject to
     a Voting Agreement, dated as of December 21, 1997, among the Stockholders
     named therein and American International Group, Inc.,
 
                                      III-2

<PAGE>   140
 
     which, among other things, (a) restricts the sale or transfer of such
     shares except in accordance therewith, and (b) restricts the voting of such
     shares except in accordance therewith."
 
In the event that Parent requests that a proxy be executed and delivered by
Stockholder to it pursuant to Section 2 hereof, Stockholder shall promptly
surrender to the Company the certificates representing the Shares covered by
such proxy and cause the foregoing legend to be revised to add to the end of
such legend the following words:
 
     ", and such shares are also subject to an irrevocable proxy under Section
     607.0722 of the Florida Business Corporation Act."
 
Stockholder shall provide Parent with reasonably satisfactory evidence of its
compliance with this Section 6 on or prior to the date five business days after
the execution hereof with respect to Shares in his possession (or within 30 days
with respect to Shares not in his possession) or of the request relating to
Stockholder's proxy, as the case may be.
 
     7.  Additional Purchases.  Each of the Stockholders severally agrees that
in the event (i) any stock dividend, stock split, recapitalization,
reclassification, combination or exchange of shares of capital stock of the
Company on, of or affecting the Shares of a Stockholder, (ii) such Stockholder
purchases or otherwise acquires beneficial ownership of any shares of Company
Common Stock after the execution of this Agreement, or (iii) such Stockholder
voluntarily acquires the right to vote or share in the voting of any shares of
Company Common Stock other than the Shares (collectively, "New Shares"), such
Stockholder agrees to deliver promptly to Parent upon request of Parent an
irrevocable proxy substantially in the form attached hereto as Exhibit B with
respect to such New Shares. Each of the Stockholders also severally agrees that
any New Shares acquired or purchased by him or her shall be subject to the terms
of this Agreement to the same extent as if they constituted Shares.
 
     8.  Specific Performance.  Each party hereto severally acknowledges that it
will be impossible to measure in money the damage to the other party if the
party hereto fails to comply with any of the obligations imposed by this
Agreement, that every such obligation is material and that, in the event of any
such failure, the other party will not have an adequate remedy at law or
damages. Accordingly, each party hereto severally agrees that injunctive relief
or other equitable remedy, in addition to remedies at law or damages, is the
appropriate remedy for any such failure and will not oppose the granting of such
relief on the basis that the other party has an adequate remedy at law. Each
party hereto severally agrees that it will not seek, and agrees to waive any
requirement for, the securing or posting of a bond in connection with any other
party's seeking or obtaining such equitable relief.

December 21, 1997
 
The Board of Directors
American Bankers Insurance Group, Inc.
11222 Quail Roost Drive
Miami, Florida 33157-6596
 
Members of the Board:
 
     You have requested our opinion as to the fairness, from a financial point
of view, to the holders of the common stock, par value $1.00 per share ("ABI
Common Stock"), and to the holders of the $3.125 Series B Convertible Preferred
Stock, no par value ("ABI Preferred Stock") of American Bankers Insurance Group,
Inc. ("American Bankers") of the consideration to be received by such holders
pursuant to the terms of and subject to the conditions set forth in the
Agreement and Plan of Merger, dated as of December 21, 1997 (the "Merger
Agreement"), by and among American International Group, Inc. ("AIG"), a wholly
owned subsidiary of AIG ("Merger Sub") and American Bankers. As more fully
described in the Merger Agreement, (A) American Bankers will be merged with and
into Merger Sub (the "Merger"), (B) each outstanding share of ABI Common Stock
will be valued at $47.00 and will be converted into the right to receive, at the
option of the holder thereof (subject to certain limitations specified in the
Merger Agreement), (i) $47.00 in cash or (ii) shares of common stock, par value
$2.50 per share, of AIG ("AIG Common Stock"), calculated by dividing $47.00 by
the average closing price of AIG Common Stock for the ten trading days preceding
the third trading day before the closing date of the Merger, provided that if
such calculation would require AIG to issue more than .4495 of a share of AIG
Common Stock per share of ABI Common Stock, AIG may elect to issue not more than
 .4495 of a share of AIG Common Stock and pay the balance of the purchase price
per share of ABI Common Stock in cash (the "Common Stock Merger Consideration"),
and (C) each outstanding share of ABI Preferred Stock will be converted into the
right to receive one preferred share of AIG, no par value ("AIG Preferred
Stock") having the terms described in the Merger Agreement (the "Preferred Stock
Merger Consideration").
 
     In arriving at our opinion, we reviewed the Merger Agreement and held
discussions with certain senior officers, directors and other representatives
and advisors of American Bankers and certain senior officers and other
representatives and advisors of AIG concerning the businesses, operations and
prospects of American Bankers and AIG. We examined certain publicly available
business and financial information relating to American Bankers and AIG as well
as certain financial forecasts for American Bankers and other information and
data for American Bankers and AIG which were provided to or otherwise discussed
with us by the respective managements of American Bankers and AIG, including
information relating to certain strategic implications and operational benefits
anticipated to result from the Merger. We reviewed the financial terms of the
Merger as set forth in the Merger Agreement in relation to, among other things:
current and historical market prices and trading volumes of the ABI Common Stock
and the AIG Common Stock; the historical and projected earnings and other
operating data of American Bankers and AIG; and the capitalization and financial
condition of American Bankers and AIG. We considered, to the extent publicly
available, the financial terms of certain other transactions recently effected
which we considered relevant in evaluating the Merger and analyzed certain
financial, stock market and other publicly available information relating to the
businesses of other companies whose operations we considered relevant in
evaluating those of American Bankers and AIG. We also evaluated the potential
pro forma financial impact of the Merger on AIG. In connection with our
engagement, we were not requested to and did not approach, or hold discussions
with, third parties to solicit indications of interest in the possible
acquisition of American Bankers. In addition to the foregoing, we conducted such
other analyses and examinations and considered such other financial, economic
and market criteria as we deemed appropriate in arriving at our opinion.
 
     In rendering our opinion, we have assumed and relied, without independent
verification, upon the accuracy and completeness of all financial and other
information and data publicly available or furnished to or otherwise reviewed by
or discussed with us. We have also assumed with your consent, that the final
terms of the Merger Agreement reviewed by us in draft form will not vary
materially from the draft reviewed by us. With respect to financial forecasts
and other information and data provided to or otherwise reviewed by or
 
                                      IV-1

The Board of Directors

discussed with us, we have been advised by the management of American Bankers
that such forecasts and other information and data were reasonably prepared on
bases reflecting the best currently available estimates and judgments of the
management of American Bankers as to the future financial performance of
American Bankers and the strategic implications and operational benefits
anticipated to result from the Merger. Our opinion, as set forth herein, relates
to the relative values of American Bankers and AIG. We are not expressing any
opinion as to what the value of the AIG Common Stock or the AIG Preferred Stock
actually will be when issued pursuant to the Merger or the price at which the
AIG Common Stock or the AIG Preferred Stock will trade subsequent to the Merger.
We have not made or been provided with an independent evaluation or appraisal of
the assets or liabilities (contingent or otherwise) of American Bankers and AIG
nor have we made any physical inspection of the properties or assets of American
Bankers and AIG. Our opinion is necessarily based upon information available to
us, and financial, stock market and other conditions and circumstances existing
and disclosed to us, as of the date hereof.
 
     Smith Barney Inc. and Salomon Brothers Inc, collectively doing business as
Salomon Smith Barney, have acted as financial advisors to American Bankers in
connection with the proposed Merger and will receive a fee for such services, a
significant portion of which is contingent upon the consummation of the Merger.
We also will receive a fee in connection with the delivery of this opinion. We
may have in the past provided investment banking services to American Bankers
and AIG, for which services we may have received compensation. In the ordinary
course of our business, we and our affiliates may actively trade or hold the
securities of American Bankers and AIG for our own account or for the account of
our customers and, accordingly, may at any time hold a long or short position in
such securities. In addition, we and our affiliates (including Travelers Group
Inc. and its affiliates) may maintain relationships with American Bankers and
AIG.
 
     Our advisory services and the opinion expressed herein are provided for the
information of the Board of Directors of American Bankers in its evaluation of
the proposed merger, and our opinion is not intended to be and does not
constitute a recommendation to any stockholder as to how such stockholder should
vote on the proposed Merger. Our opinion may not be published or otherwise used
or referred to, nor shall any public reference to Salomon Smith Barney be made,
without our prior written consent.
 
     Based upon and subject to the foregoing, our experience as investment
bankers, our work as described above and other factors we deemed relevant, we
are of the opinion that, as of the date hereof, (i) the Common Stock Merger
Consideration is fair, from a financial point of view, to the holders of ABI
Common Stock and (ii) the Preferred Stock Merger Consideration is fair, from a
financial point of view, to the holders of ABI Preferred Stock.
 
                                          Very truly yours,
 
                                               /s/ SALOMON SMITH BARNEY

CERTIFICATE OF DESIGNATION OF AIG $3.125 CUMULATIVE CONVERTIBLE SERIAL PREFERRED
                                STOCK, SERIES C
 
     Section I.  Designation of Series and Number of Shares to be Initially
Issuable Therein.  This series of Preferred Stock shall be designated "$3.125
Cumulative Convertible Serial Preferred Stock, Series C" (hereinafter called the
"Series C Preferred Stock"), $5.00 par value, of which 2,300,000 shares shall be
initially issuable.
 
     Section II.  Rank.  All shares of Series C Preferred Stock shall rank
prior, both as to payment of dividends and as to distributions of assets upon
liquidation, dissolution or winding up of the Company, whether voluntary or
involuntary, to all Junior Stock.
 
     Section III.  Dividends.  The holders of Series C Preferred Stock shall be
entitled to receive, when, as and if declared by the Board of Directors out of
funds at the time legally available therefor, dividends at the rate of $3.125
per annum per share, and no more, which shall be fully cumulative, shall accrue
without interest from [February 1, 1998]* (on a daily basis whether or not such
amounts would be available at that time for distribution to holders of shares of
Series C Preferred Stock) and shall be payable in cash quarterly in arrears on
February 1, May 1, August 1 and November 1 of each year commencing [May 1,
1998]* (with respect to the period from [February 1, 1998 to May 1, 1998]*)
(except that if any such date is not a Business Day, then such dividend shall be
payable on the next Business Day) to holders of record as they appear upon the
stock transfer books of the Company on such record dates, not more than sixty
days nor less than ten days preceding the payment dates for such dividends, as
are fixed by the Board of Directors (or, to the extent permitted by applicable
law, a duly authorized committee thereof). In no event shall any such dividend
record date be fixed less than (a) six Business Days prior to any date fixed for
the redemption of the Series C Preferred Stock or (b) with respect to the
dividend payment date occurring on August 1, 2000 less than ten Business Days
prior to any date fixed for such redemption. Subject to the next paragraph of
this Section III, dividends on account of arrears for any past dividend period
may be declared and paid at any time, without reference to any regular dividend
payment date. The amount of dividends payable per share of Series C Preferred
Stock for each quarterly dividend period shall be computed by dividing the
annual dividend amount by four. The amount of dividends payable for any period
shorter than a full quarterly period shall be computed on the basis of a 360-day
year of twelve 30-day months. No interest shall be payable in respect of any
dividend payment on the Series C Preferred Stock which may be in arrears.
 
     No dividends or other distributions, other than dividends payable solely in
shares of Junior Stock, shall be declared, paid or set apart for payment on
shares of Junior Dividend Stock, unless and until all accrued and unpaid
dividends on the Series C Preferred Stock for all dividend payment periods
ending on or before the payment date of such dividends or other distributions on
Junior Dividend Stock shall have been paid or declared and set apart for
payment.
 
     No payment on account of the purchase, redemption, retirement or other
acquisition of shares of Junior Dividend Stock or Junior Liquidation Stock shall
be made unless and until all accrued and unpaid dividends on the Series C
Preferred Stock for the then current period and all dividend payment periods
ending on or before such payment for such Junior Dividend Stock or Junior
Liquidation Stock shall have been paid or declared and set apart for payment;
provided, however, that the restrictions set forth in this sentence shall not
apply to the purchase, redemption, retirement, or other acquisition of Junior
Stock in exchange solely for Junior Stock.
 
     No full dividends shall be declared, paid or set apart for payment on
shares of Parity Dividend Stock for any period unless full cumulative dividends
have been, or contemporaneously are, paid or declared and set apart for such
payment on the Series C Preferred Stock for all dividend payment periods ending
on or before the payment date of such dividends on Parity Dividend Stock. No
dividends shall be paid on Parity Dividend Stock except on dates on which
dividends are paid on the Series C Preferred Stock. All dividends paid or
declared and set apart for payment on the Series C Preferred Stock and the
Parity Dividend Stock shall be
 
- ---------------
 
* The first dividend payment will be paid in respect of the full quarterly
  period in which closing occurs.
 
                                       V-1

paid or declared and set apart for payment pro rata so that the amount of
dividends paid or declared and set apart for payment per share on the Series C
Preferred Stock and the Parity Dividend Stock on any date shall in all cases
bear to each other the same ratio that accrued and unpaid dividends to the date
of payment on the Series C Preferred Stock and the Parity Dividend Stock bear to
each other.
 
     No payment on account of the purchase, redemption, retirement or other
acquisition of shares of Parity Dividend Stock or Parity Liquidation Stock shall
be made, and, other than dividends to the extent permitted by the preceding
paragraph, no distributions shall be declared, paid or set apart for payment on
shares of Parity Dividend Stock or Parity Liquidation Stock, unless and until
all accrued and unpaid dividends on the Series C Preferred Stock for all
dividend payment periods ending on or before such payment for, or the payment
date of such distributions on, such Parity Dividend Stock or Parity Liquidation
Stock shall have been paid or declared and set apart for payment; provided,
however, that the restrictions set forth in this sentence shall not apply to the
purchase, redemption, retirement, or other acquisition of Parity Dividend Stock
or Parity Liquidation Stock either (A) pursuant to any employee or director
incentive or benefit plan or arrangement (including any employment, severance or
consulting agreement) of the Company or any subsidiary of the Company hereafter
adopted or (B) in exchange solely for Junior Stock.
 
     Any reference to "distribution" contained in this Section III shall not be
deemed, except as expressly stated, to include any distribution made in
connection with any liquidation, dissolution or winding up of the Company,
whether voluntary or involuntary.
 
     Section IV.  Liquidation Preference.  In the event of a liquidation,
dissolution or winding up of the Company, whether voluntary or involuntary, the
holders of shares of Series C Preferred Stock shall be entitled to receive out
of the assets of the Company available for distribution to stockholders an
amount equal to the dividends accrued and unpaid on such shares on the date of
final distribution to such holders, whether or not earned or declared, without
interest, plus a sum equal to $50 per share, and no more, before any payment
shall be made or any assets distributed to the holders of shares of Junior
Stock; provided, however, that such rights shall accrue to the holders of shares
of Series C Preferred Stock only with respect to assets (if any) remaining after
the Company's payment obligations with respect to the liquidation preferences of
the shares of any class or series of the Company's capital stock hereafter
issued ranking prior to the Series C Preferred Stock as to distributions of
assets upon such liquidation, dissolution or winding up ("Senior Liquidation
Stock") are fully met. The entire assets of the Company available for
distribution to stockholders after the liquidation preferences of the shares of
Senior Liquidation Stock are fully met shall be distributed ratably among the
holders of the Series C Preferred Stock and any Parity Liquidation Stock in
proportion to the respective preferential amounts to which each is entitled (but
only to the extent of such preferential amounts). After payment in full of the
liquidation preferences of the shares of the Series C Preferred Stock, the
holders of such shares shall not be entitled to any further participation in any
distribution of assets by the Company. The voluntary sale, lease, exchange or
transfer of all or substantially all of the Company's property or assets to, or
its consolidation or merger with one or more corporations shall not be deemed to
be considered a voluntary or involuntary liquidation, dissolution or winding up
of the Company.
 
     Section V.  Redemption at Option of the Company.  The Series C Preferred
Stock may not be redeemed by the Company prior to August 7, 2000. On and after
such date, the Series C Preferred Stock may be redeemed by the Company, at its
option on any date set by the Board of Directors, in whole or in part at any
time, subject to the limitations, if any, imposed by the Florida Business
Corporation Act (the "FBCA") (assuming the Company were then incorporated under
the FBCA), for an amount in cash equal to the Redemption Price.
 
     In case of the redemption of less than all of the then outstanding Series C
Preferred Stock, the Company shall designate by lot, or in such other manner as
the Board of Directors may determine to be fair, the shares to be redeemed, or
shall effect such redemption pro rata. Notwithstanding the foregoing, the
Company shall not redeem less than all of the Series C Preferred Stock at any
time outstanding until all dividends accrued and in arrears upon all Series C
Preferred Stock then outstanding shall have been paid in full for all past
dividend periods.
 
                                       V-2

<PAGE>   150
 
     Not more than ninety nor less than thirty days prior to the date fixed for
redemption by the Board of Directors, notice thereof by first class mail,
postage prepaid, shall be given to the holders of record of the shares of Series
C Preferred Stock to be redeemed, addressed to such holders at their last
addresses as shown upon the stock transfer books of the Company. Each such
notice of redemption shall specify the date fixed for redemption, the Redemption
Price, the place or places of payment, that payment will be made upon
presentation and surrender of the shares of Series C Preferred Stock, that on
and after the date fixed for redemption dividends will cease to accrue on such
shares, the then-effective conversion price pursuant to Section VI, and that the
right of holders to convert shares of Series C Preferred Stock shall terminate
at 5:00 p.m. New York City time on the Business Day prior to the date fixed for
redemption and if such conversion right is not exercised prior to such time,
such conversion right will be lost (unless the Company defaults in the payment
of the Redemption Price).
 
     Any notice that is mailed as herein provided shall be conclusively presumed
to have been duly given, whether or not the holder of shares of Series C
Preferred Stock receives such notice; and failure to give such notice by mail,
or any defect in such notice, to the holders of any shares designated for
redemption shall not affect the validity of the proceedings for the redemption
of any other shares of Series C Preferred Stock. On or after the date fixed for
redemption as stated in such notice, each holder of the shares called for
redemption shall surrender the certificate evidencing such shares to the Company
at the place designated in such notice and shall thereupon be entitled to
receive payment of the Redemption Price. If less than all the shares evidenced
by any such surrendered certificate are redeemed, a new certificate shall be
issued evidencing the unredeemed shares.
 
     No fractional shares of Series C Preferred Stock shall be issued upon
redemption of less than all Series C Preferred Stock. If more than one
certificate evidencing shares of Series C Preferred Stock shall be held at one
time by the same holder, the number of full shares issuable upon redemption of
less than all of such shares of Series C Preferred Stock shall be computed on
the basis of the aggregate number of shares of Series C Preferred Stock so held.
Instead of any fractional share of Series C Preferred Stock that would otherwise
be issuable to a holder upon redemption of less than all shares of Series C
Preferred Stock, the Company shall pay a cash adjustment in respect of such
fractional share in an amount equal to the same fraction of the fair value per
share of Series C Preferred Stock (as determined in good faith by the Board of
Directors or in any manner prescribed by the Board of Directors) at the close of
business on the date fixed for redemption.
 
     Notice having been given as aforesaid, if, on the date fixed for
redemption, funds necessary for the redemption shall be available therefor and
shall have been deposited with a bank or trust company with irrevocable
instructions and authority to pay the Redemption Price to the holders of the
Series C Preferred Stock, then, notwithstanding that the certificates evidencing
any shares so called for redemption shall not have been surrendered, dividends
with respect to the shares so called shall cease to accrue on and after the date
fixed for redemption, such shares shall no longer be deemed outstanding, the
holders thereof shall cease to be stockholders of the Company and all rights
whatsoever with respect to the shares so called for redemption (except the right
of the holders to receive the Redemption Price without interest upon surrender
of their certificates therefor) shall terminate. If funds legally available for
such purpose are not sufficient for redemption of the shares of Series C
Preferred Stock which were to be redeemed, then the certificates evidencing such
shares shall be deemed not to be surrendered, such shares shall remain
outstanding, and the right of holders of shares of Series C Preferred Stock
thereafter shall continue to be only those of a holder of shares of the Series C
Preferred Stock.
 
     Upon an optional redemption by the Company, if at any time the Company does
not pay amounts sufficient to redeem all Series C Preferred Stock, then such
funds which are paid shall be applied to redeem such shares of Series C
Preferred Stock as the Company may designate by lot or in such other manner as
the Board of Directors may determine to be fair, or such redemption shall be
effected pro rata.
 
     The shares of Series C Preferred Stock shall not be subject to the
operation of any mandatory purchase, retirement or sinking fund.

Section VI.  Conversion Privilege.
 
     (a) Right of Conversion.  Each share of Series C Preferred Stock shall be
convertible at the option of the holder thereof, at any time prior to 5:00 p.m.
New York City time on the Business Day prior to the date fixed for redemption of
such share as herein provided, into fully paid and nonassessable shares of
Common Stock, at the rate of that number of shares of Common Stock for each full
share of Series C Preferred Stock that is equal to $50 divided by the conversion
price applicable per share of Common Stock, or into such additional or other
securities, cash or property and at such other rates as required in accordance
with the provisions of this Section VI. For purposes of this resolution, the
"conversion price" applicable per share of Common Stock shall initially be equal
to $ __ * and shall be adjusted from time to time in accordance with the
provisions of this Section VI.
 
     (b) Conversion Procedures.  Any holder of shares of Series C Preferred
Stock desiring to convert such shares into Common Stock shall surrender the
certificate or certificates evidencing such shares of Series C Preferred Stock
at the office of the transfer agent for the Series C Preferred Stock, which
certificate or certificates, if the Company shall so require, shall be duly
endorsed to the Company or in blank, or accompanied by proper instruments of
transfer to the Company or in blank, accompanied by irrevocable written notice
to the Company that the holder elects so to convert such shares of Series C
Preferred Stock and specifying the name or names (with address or addresses) in
which a certificate or certificates evidencing shares of Common Stock are to be
issued.
 
     No payments or adjustments in respect of dividends on shares of Series C
Preferred Stock surrendered for conversion or on account of any dividend on the
Common Stock issued upon conversion shall be made upon the conversion of any
shares of Series C Preferred Stock; provided, however, that:
 
          (i) if a dividend record date fixed for the Series C Preferred Stock
     as established herein results in a holder who undertakes conversion being
     eligible to receive on any dividend payment date both a dividend on the
     Series C Preferred Stock and a dividend on the Common Stock issued upon
     conversion thereof, then such holder shall be entitled to receive only the
     higher of such dividend amounts; and
 
          (ii) if the Company shall, by dividend or otherwise, declare or make a
     distribution on its Common Stock referred to in Section VI(c)(iv) or
     VI(c)(v) (including, without limitation, dividends or distributions
     referred to in the last sentence of Section VI(c)(iv)), the holder of each
     share of Series C Preferred Stock, upon the conversion thereof subsequent
     to the close of business on the date fixed for the determination of
     stockholders entitled to receive such distribution and prior to the
     effectiveness of the conversion price adjustment in respect of such
     distribution, shall also be entitled to receive for each share of Common
     Stock into which such share of Series C Preferred Stock is converted, the
     portion of the shares of Common Stock, rights, warrants, evidences of
     indebtedness, shares of capital stock, cash and assets so distributed
     applicable to one share of Common Stock; provided, however, that at the
     election of the Company (whose election shall be evidenced by a resolution
     of the Board of Directors) with respect to all holders so converting, the
     Company may, in lieu of distributing to such holder any portion of such
     distribution not consisting of cash or securities of the Company, pay such
     holder an amount in cash equal to the fair market value thereof (as
     determined in good faith by the Board of Directors, whose determination
     shall be conclusive and described in a resolution of the Board of
     Directors). If any conversion of a share of Series C Preferred Stock
     described in the immediately preceding sentence occurs prior to the payment
     date for a distribution to holders of Common Stock which the holder of the
     share of Series C Preferred Stock so converted is entitled to receive in
     accordance with the immediately preceding sentence, the Company may elect
     (such election to be evidenced by a resolution of the Board of Directors)
     to distribute to such holder a due bill for the shares of Common Stock,
     rights, warrants, evidences of indebtedness, shares of capital stock, cash
     or assets to which such holder is so entitled, provided that such due bill
     (x) meets any applicable requirements of the principal national securities
     exchange or other market on which the Common Stock is then traded and (y)
     requires payment or delivery of such shares of Common Stock, rights,
     warrants, evidences of indebtedness, shares of capital stock, cash or
     assets no later than the date of payment or delivery thereof to holders of
     shares of Common Stock receiving such distribution.

     The Company shall, as soon as practicable after such deposit of
certificates evidencing shares of Series C Preferred Stock accompanied by the
written notice and compliance with any other conditions herein contained,
deliver at such office of such transfer agent to the person for whose account
such shares of Series C Preferred Stock were so surrendered, or to the nominee
or nominees of such person, certificates evidencing the number of full shares of
Common Stock to which such person shall be entitled as aforesaid, together with
a cash adjustment in respect of any fraction of a share of Common Stock as
hereinafter provided. Such conversion shall be deemed to have been made as of
the date of such surrender of the shares of Series C Preferred Stock to be
converted, and the person or persons entitled to receive the Common Stock
deliverable upon conversion of such Series C Preferred Stock shall be treated
for all purposes as the record holder or holders of such Common Stock on such
date.
 
     (c) Adjustment of Conversion Price.  The conversion price at which a share
of Series C Preferred Stock is convertible into Common Stock shall be subject to
adjustment from time to time as follows:
 
          (i) In case the Company shall pay or make a dividend or other
     distribution on its Common Stock exclusively in Common Stock or shall pay
     or make a dividend or other distribution on any other class or series of
     capital stock of the Company which dividend or distribution includes Common
     Stock, the conversion price in effect at the opening of business on the day
     following the date fixed for the determination of stockholders entitled to
     receive such dividend or other distribution shall be reduced by multiplying
     such conversion price by: A/(A + B), where:
 
        A = the number of shares of Common Stock outstanding at the close of
            business on the date fixed for such determination; and
 
        B = the total number of shares of Common Stock constituting such
dividend or other distribution,
 
     such reduction to become effective immediately after the opening of
     business on the day following the date fixed for such determination. For
     purposes of this subparagraph (i), the number of shares of Common Stock at
     any time outstanding shall not include shares held in the treasury of the
     Company.
 
          (ii) In case the Company shall pay or make a dividend or other
     distribution on its Common Stock consisting exclusively of, or shall
     otherwise issue to all holders of its Common Stock, rights or warrants
     entitling the holders thereof to subscribe for or purchase shares of Common
     Stock at a price per share less than the Current Market Price Per Share of
     the Common Stock on the date fixed for the determination of stockholders
     entitled to receive such rights or warrants, the conversion price in effect
     at the opening of business on the day following the date fixed for such
     determination shall be reduced by multiplying such conversion price by:
     (A + B)/(A + C), where:
 
        A = the number of shares of Common Stock outstanding at the close of
            business on the date fixed for such determination,
 
        B = the number of shares of Common Stock which the aggregate of the
            offering price of the total number of shares of Common Stock so
            offered for subscription or purchase would purchase at such Current
            Market Price Per Share, and
 
        C = the number of shares of Common Stock so offered for subscription or
            purchase,
 
     such reduction to become effective immediately after the opening of
     business on the day following the date fixed for such determination.
 
          In case any rights or warrants referred to in this subparagraph (ii)
     in respect of which an adjustment shall have been made shall expire
     unexercised within 45 days after the shares shall have been distributed or
     issued by the Company the conversion price shall be readjusted at the time
     of such expiration to the
 
                                       V-5

<PAGE>   153
 
     conversion price that would have been in effect if no adjustment had been
     made on account of the distribution or issuance of such expired rights or
     warrants. In the event the Company adopts a stockholder rights plan (a
     "rights plan") that affords stockholders of the Company rights ("plan
     purchase rights") to purchase shares of Common Stock, or shares of common
     stock of a corporation that enters into certain business combinations or
     other transactions with the Company, following the occurrence of certain
     triggering events (each, a "triggering event"), then for the purposes of
     this Section VI(c)(ii) if both the separation of the plan purchase rights
     from shares of Common Stock and a triggering event shall have occurred, the
     later to occur of such events shall be deemed to constitute an issuance of
     rights to purchase shares of the related common stock.
 
          (iii) In case outstanding shares of Common Stock shall be subdivided
     into a greater number of shares of Common Stock, the conversion price in
     effect at the opening of business on the day following the day upon which
     such subdivision becomes effective shall be proportionately reduced, and
     conversely, in case outstanding shares of Common Stock shall be combined
     into a smaller number of shares of Common Stock, the conversion price in
     effect at the opening of business on the day following the day upon which
     such combination becomes effective shall be proportionately increased, such
     reduction or increase, as the case may be, to become effective immediately
     after the opening of business on the day following the day upon which such
     subdivision or combination becomes effective.
 
          (iv) In case the Company shall, by dividend or otherwise, distribute
     to all holders of its Common Stock evidences of its indebtedness, shares of
     any class or series of capital stock, cash or assets (including securities,
     but excluding any rights or warrants referred to in subparagraph (ii) of
     this Section VI(c), any dividend or distribution paid exclusively in cash
     and any dividend or distribution referred to in subparagraph (i) of this
     Section VI(c)), the conversion price shall be reduced so that the same
     shall equal the price determined by multiplying the conversion price in
     effect immediately prior to the effectiveness of the conversion price
     reduction contemplated by this subparagraph (iv) by: (A -- B)/A, where:
 
        A = the Current Market Price Per Share of the Common Stock on the date
            fixed for the payment of such distribution (the "Reference Date"),
            and
 
        B = the fair market value (as determined in good faith by the Board of
            Directors, whose determination shall be conclusive and described in
            a resolution of the Board of Directors), on the Reference Date, of
            the portion of the evidence of indebtedness, shares of capital
            stock, cash and assets so distributed applicable to one share of
            Common Stock,
 
     such reduction to become effective immediately prior to the opening of
     business on the day following the Reference Date, provided, however, that
     for purposes of this subparagraph (iv), any dividend or distribution that
     includes shares of Common Stock or rights or warrants to subscribe for or
     purchase shares of Common Stock shall be deemed instead to be (1) a
     dividend or distribution of the evidences of indebtedness, cash, assets or
     shares of capital stock other than such shares of Common Stock or rights or
     warrants (making any further conversion price reduction required by this
     subparagraph (iv)) immediately followed by (2) a dividend or distribution
     of such shares of Common Stock or such rights or warrants (making any
     further conversion price reduction required by subparagraph (i) or (ii) of
     this Section VI(c), except (A) the Reference Date of such dividend or
     distribution as defined in this subparagraph (iv) shall be substituted as
     "the date fixed for the determination of stockholders entitled to receive
     such dividend or other distribution", "the date fixed for the determination
     of stockholders entitled to receive such rights or warrants" and "the date
     fixed for such determination" within the meaning of subparagraph (i) and
     (ii) of this Section VI(c) and (B) any shares of Common Stock included in
     such dividend or distribution shall not be deemed "outstanding at the close
     of business on the date fixed for such determination" within the meaning of
     subparagraph (i) of this Section VI(c)). If the Board of Directors
     determines the fair market value of any distribution for purposes of this
     subparagraph (iv) by reference to the actual or when issued trading market
     for any securities comprising such distribution, it must in doing so
     consider the prices in such market over the same period used in computing
     the Current Market Price Per Share of Common Stock.
 
                                       V-6

<PAGE>   154
 
          (v) In case the Company shall pay or make a dividend or other
     distribution on its Common Stock exclusively in cash (excluding (A) cash
     that is part of the distribution referred to in (iv) above and, (B) in the
     case of any quarterly cash dividend on the Common Stock, the portion
     thereof that does not exceed the per share amount of the next preceding
     quarterly cash dividend on the Common Stock (as adjusted to appropriately
     reflect any of the events referred to in subparagraph (i), (ii), (iii),
     (iv) and (v) of this Section VI(c)), or all of such quarterly cash dividend
     if the amount thereof per share amount of Common Stock multiplied by four
     does not exceed 15% of the Current Market Price Per Share of the Common
     Stock on the Trading Day next preceding the date of declaration of such
     dividend), the conversion price shall be reduced so that the same shall
     equal the conversion price in effect immediately prior to the effectiveness
     of the conversion price reduction contemplated by this subparagraph (v) by:
     (A -- B)/A, where:
 
        A = the Current Market Price Per Share of the Common Stock on the date
            fixed for the payment of such distribution, and
 
        B = the amount of cash so distributed and not excluded as provided above
            applicable to one share of Common Stock,
 
     such reduction to become effective immediately prior to the opening of
     business on the day following the date fixed for the payment of such
     distribution.
 
          (vi) No adjustment in the conversion price shall be required unless
     such adjustment would require an increase or decrease of at least 1% in the
     conversion price; provided, however, that any adjustments which by reason
     of this subparagraph (vi) are not required to be made shall be carried
     forward and taken into account in any subsequent adjustment.
 
          (vii) Whenever the conversion price is adjusted as herein provided:
     (1) the Company shall compute the adjusted conversion price and shall
     prepare a certificate signed by the Treasurer of the Company setting forth
     the adjusted conversion price and showing in reasonable detail the facts
     upon which such adjustment in based, and such certificate shall forthwith
     be filed with the transfer agent for the Series C Preferred Stock; and (2)
     a notice stating that the conversion price has been adjusted and setting
     forth the adjusted conversion price shall forthwith be required, and as
     soon as practicable after it is required, such notice shall be mailed by
     the Company to all record holders of shares of Series C Preferred Stock at
     their last addresses as they shall appear upon the stock transfer books of
     the Company.
 
          (viii) The Company from time to time may reduce the conversion price
     by any amount for any period of time if the period is at least twenty days,
     the reduction is irrevocable during the period and the Board of Directors
     of the Company shall have made a determination that such reduction would be
     in the best interest of the Company, which determination shall be
     conclusive. Whenever the conversion price is reduced pursuant to the
     preceding sentence, the Company shall mail to holders of record of the
     Series C Preferred Stock a notice of the reduction at least fifteen days
     prior to the date the reduced conversion price takes effect, and such
     notice shall state the reduced conversion price and the period it will be
     in effect.
 
     (d) No Fractional Shares.  No fractional shares of Common Stock shall be
issued upon conversion of Series C Preferred Stock. If more than one certificate
evidencing shares of Series C Preferred Stock shall be surrendered for
conversion at one time by the same holder, the number of full shares issuable
upon conversion thereof shall be computed on the basis of the aggregate number
of shares of Series C Preferred Stock so surrendered. Instead of any fractional
share of Common Stock that would otherwise be issuable to a holder upon
conversion of any shares of Series C Preferred Stock, the Company shall pay a
cash adjustment in respect of such fractional share in an amount equal to the
same fraction of the market price per share of Common Stock (as determined by
the Board of Directors or in any manner prescribed by the Board of Directors,
which, so long as the Common Stock is listed on the New York Stock Exchange or
quoted on the Nasdaq National Market System, shall be the reported last sale
price regular way) at the close of business on the day of conversion.
 
                                       V-7

<PAGE>   155
 
     (e) Reclassification, Consolidation, Merger or Sale of Assets.  In the
event that the Company shall be a party to any transaction (including without
limitation any recapitalization or reclassification of the Common Stock (other
than a change in par value, or from par value to no par value, or from no par
value to par value, or as a result of a subdivision or combination of the Common
Stock), any consolidation of the Company with, or merger of the Company into,
any other person, any merger of another person into the Company (other than a
merger which does not result in a reclassification, conversion, exchange or
cancellation of outstanding shares of Common Stock of the Company), any sale or
transfer of all or substantially all of the assets of the Company or any share
exchange) pursuant to which the Common Stock is converted into the right to
receive other securities, cash or other property, then lawful provisions shall
be made as part of the terms of such transaction whereby the holder of each
share of Series C Preferred Stock then outstanding shall have the right
thereafter to convert such share only into (i) in the case of any such
transaction other than a Common Stock Fundamental Change and subject to funds
being legally available for such purpose under applicable law at the time of
such conversion, the kind and amount of securities, cash and other property
receivable upon such transaction by a holder of the number of shares of Common
Stock of the Company into which such share of Series C Preferred Stock might
have been converted immediately prior to such transaction, after giving effect,
in the case of any Non-Stock Fundamental Change, to any adjustment in the
conversion price required by the provisions of Section VI(h), and (ii) in the
case of a Common Stock Fundamental Change, common stock of the kind received by
holders of Common Stock as a result of such Common Stock Fundamental Change in
an amount determined pursuant to the provisions of Section VI(h). The Company or
the person formed by such consolidation or resulting from such merger or which
acquires such assets or which acquires the Company's shares, as the case may be,
shall make provisions in its certificate or articles of incorporation or other
constituent document to establish such right. Such certificate or articles of
incorporation or other constituent document shall provide for adjustments which,
for events subsequent to the effective date of such certificate or articles of
incorporation or other constituent document, shall be as nearly equivalent as
may be practicable to the adjustments provided for in this Section VI. The above
provisions shall similarly apply to successive transactions of the foregoing
type.
 
     (f) Reservation of Shares; Etc.  The Company shall at all times reserve and
keep available, free from preemptive rights out of its authorized and unissued
stock, solely for the purpose of effecting the conversion of the Series C
Preferred Stock, such number of shares of its Common Stock as shall from time to
time be sufficient to effect that conversion of all shares of Series C Preferred
Stock from time to time outstanding. The Company shall from time to time, in
accordance with the laws of the State of Delaware, in good faith and as
expeditiously as possible endeavor to cause the authorized number of shares of
Common Stock to be increased if at any time the number of shares of authorized
and unissued Common Stock shall not be sufficient to permit the conversion of
all the then-outstanding shares of Series C Preferred Stock.
 
     If any shares of Common Stock required to be reserved for purposes of
conversion of the Series C Preferred Stock hereunder require registration with
or approval of any governmental authority under any Federal or State law before
such shares may be issued upon conversion, the Company will in good faith and as
expeditiously as possible endeavor to cause such shares to be duly registered or
approved as the case may be. If the Common Stock is listed on the New York Stock
Exchange or any other national securities exchange or traded through the Nasdaq
National Market, the Company will, if permitted by the rules of such exchange or
market, list and keep listed on such exchange or make and keep eligible for
trading on such market (as the case may be), upon official notice of issuance,
all shares of Common Stock issuable upon conversion of the Series C Preferred
Stock; provided, however, that such shares of Common Stock may be delisted from
such exchange or may cease to be eligible for trading through such market (as
the case may be) if, prior to or concurrent with such delisting or cessation of
eligibility for trading, the Company causes such shares of Common Stock to be
listed on or eligible for trading through any other such exchange or market.
 
     (g) Prior Notice of Certain Events.  In case:
 
          (i) the Company shall (1) declare any dividend (or any other
     distribution) on its Common Stock, other than (A) a dividend payable in
     shares of Common Stock or (B) a dividend payable in cash out of its
     retained earnings other than any special or nonrecurring or other
     extraordinary dividend or (2) declare
 
                                       V-8

<PAGE>   156
 
     or authorize a redemption or repurchase of in excess of 10% of the
     then-outstanding shares of Common Stock; or
 
          (ii) the Company shall authorize the granting to all holders of Common
     Stock of rights or warrants to subscribe for or purchase any shares of
     stock of any class or series or of any other rights or warrants; or
 
          (iii) of any reclassification of Common Stock (other than a
     subdivision or combination of the outstanding Common Stock, or a change in
     par value, or from par value to no par value, or from no par value to par
     value), or of any consolidation or merger to which the Company is a party
     and for which approval of any shareholders of the Company shall be
     required, or of the sale or transfer of all or substantially all of the
     assets of the Company or of any share exchange whereby the Common Stock is
     converted into other securities, cash or other property; or
 
          (iv) of the voluntary or involuntary dissolution, liquidation or
     winding up of the Company;
 
then the Company shall cause to be filed with the transfer agent for the Series
C Preferred Stock, and shall cause to be mailed to the holders of record of the
Series C Preferred Stock, at their last addresses as they shall appear upon the
stock transfer books of the Company, at least ten days prior to the applicable
record or effective date hereinafter specified, a notice stating (x) the date on
which a record (if any) is to be taken for the purpose of such dividend,
distribution, redemption, repurchase, rights or warrants or, if a record is not
to be taken, the date as of which the holders of Common Stock of record to be
entitled to such dividend, distribution, redemption, rights or warrants are to
be determined or (y) the date on which such reclassification, consolidation,
merger, sale, transfer, share exchange, dissolution, liquidation or winding up
is expected to become effective and the date as of which it is expected that
holders of Common Stock of record shall be entitled to exchange their shares of
Common Stock for securities, cash or other property deliverable upon such
reclassification, consolidation, merger, sale, transfer, share exchange,
dissolution, liquidation or winding up (but no failure to mail such notice or
any defect therein or in the mailing thereof shall affect the validity of the
corporate action required to be specified in such notice).
 
     (h) Adjustments in Case of Fundamental Changes.  Notwithstanding any other
provision in this Section VI to the contrary, if any Fundamental Change occurs,
then the conversion price in effect will be adjusted immediately after such
Fundamental Change as described below. In addition, in the event of a Common
Stock Fundamental Change, each share of Series C Preferred Stock shall be
convertible solely into common stock of the kind received by holders of Common
Stock as the result of such Common Stock Fundamental Change.
 
     For purposes of calculating any adjustment to be made pursuant to this
Section VI(h) in the event of a Fundamental Change, immediately after such
Fundamental Change:
 
          (i) In the case of a Non-Stock Fundamental Change, the conversion
     price of the Series C Preferred Stock shall thereupon become the lower of
     (1) the conversion price in effect immediately prior to such Non-Stock
     Fundamental Change, but after giving effect to any other prior adjustments
     effected pursuant to this Section VI, and (2) the result of A x $50/B,
     where:
 
        A = the greater of the Applicable Price or the then applicable Reference
            Market Price, and
 
        B = (x) the then-current Redemption Price per share of Series C
            Preferred Stock or (y) for any Non-Stock Fundamental Change that
            occurs before the Series C Preferred Stock becomes redeemable by the
            Company pursuant to Section V, the applicable price per share set
            forth for the date of such Non-Stock Fundamental Change in the
            following table:

     plus, in any case referred to in this clause (y), an amount equal to all
     per share dividends on the Series C Preferred Stock accrued and unpaid
     thereon, whether or not declared, to but excluding the date of such
     Non-Stock Fundamental Change; and
 
          (ii) In the case of a Common Stock Fundamental Change, the conversion
     price of the Series C Preferred Stock in effect immediately prior to such
     Common Stock Fundamental Change, but after giving effect to any other prior
     adjustments effected pursuant to this Section VI, shall thereupon be
     adjusted by multiplying such conversion price by a fraction of which the
     numerator shall be the Purchaser Stock Price and the denominator shall be
     the Applicable Price; provided, however, that in the event of a Common
     Stock Fundamental Change in which (A) 100% by value of the consideration
     received by a holder of Common Stock is common stock of the successor,
     acquiror or other third party (and cash, if any, is paid with respect to
     any fractional interests in such common stock resulting from such Common
     Stock Fundamental Change) and (B) all of the Common Stock shall have been
     exchanged for, converted into or acquired for common stock (and cash with
     respect to fractional interests) of the successor, acquiror or other third
     party, the conversion price of the Convertible Serial Preferred Stock in
     effect immediately prior to such Common Stock Fundamental Change shall
     thereupon be adjusted by dividing such conversion price by the number of
     shares of common stock of the successor, acquiror, or other third party
     received by a holder of one share of Common Stock as a result of such
     Common Stock Fundamental Change.
 
     (i) Dividend or Interest Reinvestment Plans.  Notwithstanding the foregoing
provisions, the issuance of any shares of Common Stock pursuant to any plan
providing for the reinvestment of dividends or interest payable on securities of
the Company and the investment of additional optional amounts in shares of
Common Stock under any such plan, and the issuance of any shares of Common Stock
or options or rights to purchase such shares pursuant to any employee benefit
plan or program of the Company or pursuant to any option, warrant, right or
exercisable, exchangeable or convertible security outstanding as of the date the
Series C Preferred Stock was first designated (except as expressly provided in
Section VI(c)(ii) with respect to a separation of plan purchase rights from the
Common Stock or the occurrence of a triggering event under a rights plan), and
any issuance of plan purchase rights, shall not be deemed to constitute an
issuance of Common Stock or exercisable, exchangeable or convertible securities
by the Company to which any of the adjustment provisions described above
applies. There shall also be no adjustment of the conversion price in case of
the issuance of any stock (or securities convertible into or exchangeable for
stock) of the Company except as specifically described in this Section VI. If
any action would require adjustment of the conversion price pursuant to more
than one of the provisions described above, only one adjustment shall be made
and such adjustment shall be the amount of adjustment which has the highest
absolute value to holders of Series C Preferred Stock.
 
     (j) Plan Purchase Rights.  If and so long as any plan purchase rights are
attached to the outstanding shares of Common Stock, each share of Common Stock
issued upon conversion of the shares of Series C Preferred Stock prior to the
earliest of any separation of such plan purchase rights from the Common Stock in
accordance with the provisions of the rights plan, the date of redemption of
such plan purchase rights or the date of expiration of such plan purchase rights
shall be issued with plan purchase rights in an amount equal to the amount of
plan purchase rights then attached to each such outstanding share of Common
Stock.
 
     Section VII.  Voting Rights.
 
     (a) General.  (i) The holders of shares of Series C Preferred Stock shall
not have any voting rights except as set forth below or as otherwise from time
to time required by law. In connection with any right to vote, each holder of a
share of Series C Preferred Stock shall have one vote for each share held. Any
shares of Series C Preferred Stock owned, directly or indirectly, by any entity
of which the Company owns, directly or indirectly, a majority of the shares
entitled to vote for directors, shall not have voting rights hereunder and shall
not be counted in determining the presence of a quorum.
 
     So long as any shares of the Company's Series C Preferred Stock are
outstanding, the Company will not, without the affirmative vote or consent of
the holders of at least 66 2/3% of the outstanding shares of Series C Preferred
Stock and outstanding Parity Dividend Stock, voting or consenting (as the case
may be) as a single

class (A) amend, alter or repeal (by merger or otherwise) any provision of the
Company's Certificate of Incorporation, as may be amended or restated from time
to time, or the by-laws so as to affect adversely the relative rights,
preferences, qualifications, limitations or restrictions of the Series C
Preferred Stock, (B) effect any reclassification of the Series C Preferred
Stock, or (C) issue shares of Serial Preferred Stock to the extent that doing so
would cause the total number of shares of Serial Preferred Stock outstanding
(without giving effect to any depositary receipts or other similar instruments
through which such shares could be owned or held under Florida law assuming the
Company were then incorporated under the FBCA) after giving effect to such
issuance to exceed 3,500,000.
 
     (ii) In addition to the voting rights (if any) to which holders of Series C
Preferred Stock are entitled pursuant to the Delaware General Corporation Law,
the holders of the outstanding shares of Series C Preferred Stock shall be
entitled to vote as a class as described in paragraphs (iii) and (iv) below if
stockholder voting of the Series C Preferred Stock would be required by the FBCA
(assuming the Company were then incorporated under the FBCA) upon a proposed
amendment to the Certificate of Incorporation of the Company (or upon a plan of
merger or share exchange if such plan contains any provision that would, if
contained in a proposed amendment to the Certificate of Incorporation of the
Company, entitle such holders to vote as a class under this Section VII(a)(ii))
if the amendment would:
 
          (A) increase or decrease the aggregate number of authorized shares of
     Serial Preferred Stock;
 
          (B) effect an exchange or reclassification of all or part of the
     shares of Serial Preferred Stock into shares of another class;
 
          (C) effect an exchange or reclassification, or create a right of
     exchange, of all or part of the shares of another class into shares of
     Serial Preferred Stock;
 
          (D) change the designation, rights, preferences, or limitations of all
     or part of the shares of Serial Preferred Stock;
 
          (E) change the shares of all or part of the Serial Preferred Stock
     into a different number of shares of Serial Preferred Stock;
 
          (F) create a new class of shares having rights or preferences with
     respect to distributions or to dissolution that are prior, superior, or
     substantially equal to the shares of Serial Preferred Stock;
 
          (G) increase the rights, preferences, or number of authorized shares
     of any class that, after giving effect to the amendment, have rights or
     preferences with respect to distributions or to dissolution that are prior,
     superior, or substantially equal to the shares of Serial Preferred Stock;
 
          (H) limit or deny an existing preemptive right of all or part of the
     shares of Serial Preferred Stock;
 
          (I) cancel or otherwise affect rights to distributions or dividends
     that have accumulated but not yet been declared on all or part of the
     shares of Serial Preferred Stock;
 
     (iii) If a proposed amendment to the Certificate of Incorporation of the
Company would affect the shares of Series C Preferred Stock in one or more of
the ways described in subsection (ii) of this Section VII, the shares of Series
C Preferred Stock shall be entitled to vote as a separate class on the proposed
amendment.
 
     (iv) If a proposed amendment to the Certificate of Incorporation of the
Company that would entitle the shares of Series C Preferred Stock and one or
more other series of shares of Serial Preferred Stock to vote as separate
classes under subsections (ii) or (iii) of this Section VII (assuming the
Company were then incorporated under the FBCA) would affect shares of Series C
Preferred Stock and such one or more other series of Serial Preferred Stock in
the same or a substantially similar way, the shares of Series C Preferred Stock
and the shares of such one or more other series of Serial Preferred Stock so
affected shall vote together as a single class on the proposed amendment.
 
     (v) The shares of Series C Preferred Stock shall also be entitled to any
other voting rights afforded by Florida law (assuming the Company were then
incorporated under the FBCA).
 
     (b) Default Voting Rights.  Notwithstanding any other provision of the
Company's Certificate of Incorporation, whenever dividends on the Series C
Preferred Stock or any other class or series of Parity
 
                                      V-11

<PAGE>   159
 
Dividend Stock shall be in arrears in an aggregate amount equal to at least six
quarterly dividends (whether or not consecutive), (i) the number of members of
the Board of Directors of the Company shall be increased by two, effective at
the time of election of such directors as hereinafter provided and (ii) the
holders of shares of Series C Preferred Stock (voting separately as a class with
all other affected classes or series of Parity Dividend Stock upon which like
voting rights have been conferred and are exercisable) shall have the exclusive
right to vote for and elect such two additional directors of the Company who
shall continue to serve during the period such dividends remain in arrears. The
right of the holders of shares of Series C Preferred Stock to vote for such two
additional directors shall terminate when all accrued and unpaid dividends on
the Series C Preferred Stock and all other affected classes or series of Parity
Dividend Stock have been declared and paid or set apart for payment. The term of
office of all directors so elected shall terminate immediately upon the
termination of the right of the holders of shares of Series C Preferred Stock
and such Parity Dividend Stock to vote for such two additional directors, and
the number of directors of the Board of Directors of the Company shall
immediately thereafter be reduced by two.
 
     The foregoing right of the holders of shares of Series C Preferred Stock
with respect to the election of two directors may be exercised at any annual
meeting of shareholders or at any special meeting of shareholders held for such
purpose. If the right to elect directors shall have accrued to the holders of
shares of Series C Preferred Stock more than ninety days preceding the date
established for the next annual meeting of stockholders, the President of the
Company shall, within twenty days after the delivery to the Company at its
principal office of a written request for a special meeting signed by the
holders of at least 10% of all outstanding shares of Series C Preferred Stock,
call a special meeting of the holders of Series C Preferred Stock to be held
within sixty days after the delivery of such request for the purpose of electing
such additional directors.
 
     Notwithstanding any other provision of the Company's Certificate of
Incorporation, the holders of shares of Series C Preferred Stock and any Parity
Dividend Stock referred to above voting as a class shall have the right to
remove, without cause and at any time, and replace any directors such holders
shall have elected pursuant to this Section VII.
 
     Section VIII.  Outstanding Shares.  For purposes of this amendment, all
shares of Series C Preferred Stock issued by the Company shall be deemed
outstanding except (i) from the date fixed for redemption pursuant to Section V,
all shares of Series C Preferred Stock that have been so called for redemption
under Section V, to the extent provided thereunder; (ii) from the date of
surrender of certificates evidencing shares of Series C Preferred Stock, all
shares of Series C Preferred Stock converted into Common Stock; and (iii) from
the date of registration of transfer, all shares of Series C Preferred Stock
owned, directly or indirectly, by any entity of which the Company owns, directly
or indirectly, a majority of the shares entitled to vote for directors.
 
     Section IX.  Miscellaneous.
 
     (a) Whenever possible, each provision hereof shall be interpreted in a
manner as to be effective and valid under applicable law, but if any provision
hereof is held to be prohibited by or invalid under applicable law, such
provision shall be ineffective only to the extent of such prohibition or
invalidity, without invalidating or otherwise adversely affecting the remaining
provisions hereof. If a court of competent jurisdiction should determine that a
provision hereof would be valid or enforceable if a period of time were extended
or shortened or a particular percentage were increased or decreased, then such
court may make such change as shall be necessary to render the provision in
question effective and valid under applicable law.
 
     (b) The Company shall pay any and all stock transfer and documentary stamp
taxes that may be payable in respect of any issuance or delivery of shares of
Series C Preferred Stock or shares of Common Stock or other securities issued on
account of Series C Preferred Stock pursuant hereto or certificates or
instruments evidencing such shares or securities. The Company shall not,
however, be required to pay any such tax which may be payable in respect of any
transfer involved in the issuance or delivery of shares of Series C Preferred
Stock or Common Stock or other securities in a name other than that in which the
shares of Series C Preferred Stock with respect to which such shares or other
securities are issued or delivered were registered, or in respect of any payment
to any person with respect to any such shares or securities other than a payment
to
 
                                      V-12

<PAGE>   160
 
the registered holder thereof, and shall not be required to make any such
issuance, delivery or payment unless and until the person otherwise entitled to
such issuance, delivery or payment has paid to the Company the amount of any
such tax or has established, to the satisfaction of the Company, that such tax
has been paid or is not payable.
 
     (c) In the event that a holder of shares of Series C Preferred Stock shall
not by written notice designate the name in which shares of Common Stock to be
issued upon conversion of such shares should be registered or to whom payment
upon redemption of shares of Series C Preferred Stock should be made or the
address to which the certificates or instruments evidencing such shares or such
payment should be sent, the Company shall be entitled to register such shares
and make such payment, in the name of the holder of such Series C Preferred
Stock as shown on the records of the Company and to send the certificates or
instruments evidencing such shares or such payment, to the address of such
holder shown on the records of the Company.
 
     Section X.  Definitions.  The following definitions shall apply to terms
used in connection with the Series C Preferred Stock:

Fundamental Change, the average of the daily Closing Prices of the Common Stock
for the ten consecutive Trading Days prior to and including the record date for

Fundamental Change or Common Stock Fundamental Change, or, if there is no such
record date, the date upon which the holders of the Common Stock shall have the
right to receive such cash, securities, property or other assets, in each case,
as adjusted in good faith by the Board of Directors of the Company to

principal national securities exchange or quotation system on which the common
stock is listed or admitted to trading or quoted, or, if not listed or admitted
to trading or quoted on any national securities exchange or quotation system,
the average of the closing bid and asked prices of the common stock in the
over-the-counter market on the day in question as reported by the National
Quotation Bureau Incorporated, or a similarly generally accepted reporting

referred to with respect to such Fundamental Change in Section X(a) above has
been admitted for listing or admitted for listing subject to notice of issuance
on a national securities exchange or quoted on the Nasdaq National Market;
provided, however, that a Fundamental Change shall not be a Common Stock
Fundamental Change unless either (i) the Company continues to exist after the
occurrence of such Fundamental Change and the outstanding shares of Series C
Preferred Stock continue to exist as outstanding shares of Series C Preferred
Stock, or (ii) not later than the occurrence of such Fundamental Change, the
outstanding shares of Series C Preferred Stock are converted into or exchanged
for shares of convertible preferred stock of a corporation succeeding to the
business of the Company, which convertible preferred stock has powers,
preferences and relative, participating, optional or other rights, and
qualifications, limitations and restrictions, substantially similar to those of
the Series C Preferred Stock.

     f. "Current Market Price Per Share" shall mean, as to the Common Stock on
any date in question, the average of the daily Closing Prices for the five
consecutive Trading Days prior to and including the date in question; provided,
however, that:

     distribution requiring such computation) that required an adjustment to the
     conversion price pursuant to subparagraphs (i), (ii), (iii), (iv), or (v)
     of Section VI(c) ("Other Event") occurs after the fifth Trading Day prior
     to the day in question and prior to the Ex Date for the issuance or
     distribution requiring such computation (the "Current Event"), the Closing
     Price for each Trading Day prior to the Ex Date for such Other Event shall
     be adjusted by multiplying such Closing Price by the same fraction by which
     the conversion price is so required to be adjusted as a result of such
     Other Event,
 
          (2) if the Ex Date for any Other Event occurs after the Ex Date for
     the Current Event and on or prior to the date in question, the Closing
     Price for each Trading Day on and after the Ex Date for such Other Event
     shall be adjusted by multiplying such Closing Price by the reciprocal of
     the fraction by which the conversion price is so required to be adjusted as
     a result of such Other Event,
 
          (3) if the Ex Date for any Other Event occurs on the Ex Date for the
     Current Event, one of those events, as determined by the Company, shall be
     deemed for purposes of clauses (1) and (2) of this proviso to have an Ex
     Date occurring prior to the Ex Date for the other of those events, and
 
          (4) if the Ex Date for the Current Event is on or prior to the date in
     question, then after taking into account any adjustment required pursuant
     to clause (2) of this proviso, the Closing Price for each Trading Day on or
     after such Ex Date shall be adjusted by adding thereto the amount of any
     cash and the fair market value on the date in question (as determined in
     good faith by the Board of Directors in a manner consistent with any
     determination of such value for purposes of paragraph (iv) or (v) of
     Section VI(c), whose determination shall be conclusive and described in a
     resolution of the Board of Directors) of the portion of the rights,
     warrants, evidences of indebtedness, shares of capital stock or assets
     being distributed applicable to one share of Common Stock.
 
     g. "Ex Date" shall mean (1) when used with respect to any issuance or
distribution, the first date on which the Common Stock trades regular way on the
relevant exchange or in the relevant market from which the Closing Price was
obtained without the right to receive such issuance or distribution and (2) when
used with respect to any subdivision or combination of shares of Common Stock,
the first date on which the Common Stock trades regular way on such exchange or
in such market after the time at which such subdivision or combination becomes

constitute solely the right to receive cash, securities, property or other
assets (whether by means of an exchange offer, liquidation, tender offer,
consolidation, merger, combination, reclassification, recapitalization or
otherwise); provided, however, in the case of a plan involving more than one
such transaction or event, for purposes of adjustment of the conversion price,
such Fundamental Change shall be deemed to have occurred when substantially all
of the Common Stock of the Company shall be exchanged for, converted into, or
acquired for or constitute solely the right to receive cash, securities,
property or other assets, but the adjustment shall be based upon the highest
weighted average of consideration per share which a holder of Common Stock could
have received in such transactions or events as a result of which more than 50%
of the Common Stock of the Company shall have been exchanged for, converted
into, or acquired for or constitute solely the right to receive cash,

Fundamental Change, the average of the daily Closing Prices of the common stock
received in such Common Stock Fundamental Change for the ten consecutive Trading

the Board of Directors of the Company to appropriately reflect any of the events
referred to in subparagraphs, (i), (ii), (iii), (iv) and (v) of Section VI(c);
provided, however, if no such Closing Prices of the common stock for such

determined in good faith by the Board of Directors of the Company.

             $3.125 CUMULATIVE CONVERTIBLE SERIES B PREFERRED STOCK
 
     Section I.  Designation of Series and Number of Shares to be Initially
Issuable Therein.  This series of Preferred Stock shall be designated "$3.125
Series B Cumulative Convertible Preferred Stock" (hereinafter called the
"Convertible Preferred Stock"), no par value, of which 2,300,000 shares shall be
initially issuable.
 
     Section II.  Rank.  All shares of Convertible Preferred Stock shall rank
prior, both as to payment of dividends and as to distributions of assets upon
liquidation, dissolution or winding up of the Corporation, whether voluntary or
involuntary, to all Junior Stock.
 
     Section III.  Dividends.  The holders of Convertible Preferred Stock shall
be entitled to receive, when, as and if declared by the Board of Directors out
of funds at the time legally available therefor, dividends at the rate of $3.125
per annum per share, and no more, which shall be fully cumulative, shall accrue
without interest from the date of initial issuance of such shares of Convertible
Preferred Stock (on a daily basis whether or not such amounts would be available
at that time for distribution to holders of shares of Convertible Preferred
Stock) and shall be payable in cash quarterly in arrears on February 1, May 1,
August 1 and November 1 of each year commencing November 1, 1996 (with respect
to the period from such date of initial issuance to November 1, 1996) (except
that if any such date is not a Business Day, then such dividend shall be payable
on the next Business Day) to holders of record as they appear upon the stock
transfer books of the Corporation on such record dates, not more than sixty days
nor less than ten days preceding the payment dates for such dividends, as are
fixed by the Board of Directors (or, to the extent permitted by applicable law,
a duly authorized committee thereof). In no event shall any such dividend record
date be fixed less than (a) six Business Days prior to any date fixed for the
redemption of the Convertible Preferred Stock or (b) with respect to the
dividend payment date occurring on August 1, 2000 less than ten Business Days
prior to any date fixed for such redemption. Subject to the next paragraph of
this Section III, dividends on account of arrears for any past dividend period
may be declared and paid at any time, without reference to any regular dividend
payment date. The amount of dividends payable per share of Convertible Preferred
Stock for each quarterly dividend period shall be computed by dividing the
annual dividend amount by four. The amount of dividends payable for the initial
dividend period and any period shorter than a full quarterly period shall be
computed on the basis of a 360-day year of twelve 30-day months. No interest
shall be payable in respect of any dividend payment on the Convertible Preferred
Stock which may be in arrears.
 
     No dividends or other distributions, other than dividends payable solely in
shares of Junior Stock, shall be declared, paid or set apart for payment on
shares of Junior Dividend Stock, unless and until all accrued and unpaid
dividends on the Convertible Preferred Stock for all dividend payment periods
ending on or before the payment date of such dividends or other distributions on
Junior Dividend Stock shall have been paid or declared and set apart for
payment.
 
     No payment on account of the purchase, redemption, retirement or other
acquisition of shares of Junior Dividend Stock or Junior Liquidation Stock shall
be made unless and until all accrued and unpaid dividends on the Convertible
Preferred Stock for all dividend payment periods ending on or before such
payment for such Junior Dividend Stock or Junior Liquidation Stock shall have
been paid or declared and set apart for payment; provided, however, that the
restrictions set forth in this sentence shall not apply to the purchase,
redemption, retirement, or other acquisition of Junior Dividend Stock or Junior
Liquidation Stock either (A) pursuant to any employee or director incentive or
benefit plan or arrangement (including any employment, severance or consulting
agreement) of the Corporation or any subsidiary of the Corporation heretofore or
hereafter adopted or (B) in exchange solely for Junior Stock.
 
     No full dividends shall be declared, paid or set apart for payment on
shares of Parity Dividend Stock for any period unless full cumulative dividends
have been, or contemporaneously are, paid or declared and set apart for such
payment on the Convertible Preferred Stock for all dividend payment periods
ending on or before the payment date of such dividends on Parity Dividend Stock.
No dividends shall be paid on Parity Dividend Stock except on dates on which
dividends are paid on the Convertible Preferred Stock. All dividends paid or
declared and set apart for payment on the Convertible Preferred Stock and the
Parity Dividend Stock shall be paid or declared and set apart for payment pro
rata so that the amount of dividends paid or declared
 
                                      VI-1

<PAGE>   165
 
and set apart for payment per share on the Convertible Preferred Stock and the
Parity Dividend Stock on any date shall in all cases bear to each other the same
ratio that accrued and unpaid dividends to the date of payment on the
Convertible Preferred Stock and the Parity Dividend Stock bear to each other.
 
     No payment on account of the purchase, redemption, retirement or other
acquisition of shares of Junior Stock, Parity Dividend Stock or Parity
Liquidation Stock shall be made, and, other than dividends to the extent
permitted by the preceding paragraph, no distributions shall be declared, paid
or set apart for payment on shares of Parity Dividend Stock or Parity
Liquidation Stock, unless and until all accrued and unpaid dividends on the
Convertible Preferred Stock for all dividend payment periods ending on or before
such payment for, or the payment date of such distributions on, such Parity
Dividend Stock or Parity Liquidation Stock shall have been paid or declared and
set apart for payment; provided, however, that the restrictions set forth in
this sentence shall not apply to the purchase, redemption, retirement, or other
acquisition of Parity Dividend Stock or Parity Liquidation Stock either (A)
pursuant to any employee or director incentive or benefit plan or arrangement
(including any employment, severance or consulting agreement) of the Corporation
or any subsidiary of the Corporation hereafter adopted or (B) in exchange solely
for Junior Stock.
 
     Any reference to "distribution" contained in this Section III shall not be
deemed, except as expressly stated, to include any distribution made in
connection with any liquidation, dissolution or winding up of the Corporation,
whether voluntary or involuntary.
 
     Section IV.  Liquidation Preference.  In the event of a liquidation,
dissolution or winding up of the Corporation, whether voluntary or involuntary,
the holders of shares of Convertible Preferred Stock shall be entitled to
receive out of the assets of the Corporation available for distribution to
shareholders an amount equal to the dividends accrued and unpaid on such shares
on the date of final distribution to such holders, whether or not declared,
without interest, plus a sum equal to $50 per share, and no more, before any
payment shall be made or any assets distributed to the holders of shares of
Junior Liquidation Stock; provided, however, that such rights shall accrue to
the holders of shares of Convertible Preferred Stock only with respect to assets
(if any) remaining after the Corporation's payment obligations with respect to
the liquidation preferences of the shares of any class or series of the
Corporation's capital stock hereafter issued ranking prior to the Convertible
Preferred Stock as to distributions of assets upon such liquidation, dissolution
or winding up ("Senior Liquidation Stock") are fully met. The entire assets of
the Corporation available for distribution to shareholders after the liquidation
preferences of the shares of Senior Liquidation Stock are fully met shall be
distributed ratably among the holders of the Convertible Preferred Stock and any
Parity Liquidation Stock in proportion to the respective preferential amounts to
which each is entitled (but only to the extent of such preferential amounts).
After payment in full of the liquidation preferences of the shares of
Convertible Preferred Stock, the holders of such shares shall not be entitled to
any further participation in any distribution of assets by the Corporation. The
voluntary sale, lease, exchange or transfer of all or substantially all of the
Corporation's property or assets to, or its consolidation or merger with one or
more corporations shall not be deemed to be considered a voluntary or
involuntary liquidation, dissolution or winding up of the Corporation.
 
     Section V.  Redemption at Option of the Corporation.  The Convertible
Preferred Stock may not be redeemed by the Corporation prior to August 7, 2000.
On and after such date, the Convertible Preferred Stock may be redeemed by the
Corporation, at its option on any date set by the Board of Directors, in whole
or in part at any time, subject to the limitations, if any, imposed by the
Florida Business Corporation Act, for an amount in cash equal to the Redemption
Price.
 
     In case of the redemption of less than all of the then outstanding
Convertible Preferred Stock, the Corporation shall designate by lot, or in such
other manner as the Board of Directors may determine to be fair, the shares to
be redeemed, or shall effect such redemption pro rata. Notwithstanding the
foregoing, the Corporation shall not redeem less than all of the Convertible
Preferred Stock at any time outstanding until all dividends accrued and in
arrears upon all Convertible Preferred Stock then outstanding shall have been
paid in full for all past dividend periods.
 
     Not more than ninety nor less than thirty days prior to the date fixed for
redemption by the Board of Directors, notice thereof by first class mail,
postage prepaid, shall be given to the holders of record of the shares of
Convertible Preferred Stock to be redeemed, addressed to such holders at their
last addresses as
 
                                      VI-2

<PAGE>   166
 
shown upon the stock transfer books of the Corporation. Each such notice of
redemption shall specify the date fixed for redemption, the Redemption Price,
the place or places of payment, that payment will be made upon presentation and
surrender of the shares of Convertible Preferred Stock, that on and after the
date fixed for redemption dividends will cease to accrue on such shares, the
then-effective conversion price pursuant to Section VI, and that the right of
holders to convert shares of Convertible Preferred Stock shall terminate at 5:00
p.m. New York City time on the Business Day prior to the date fixed for
redemption and if such conversion right is not exercised prior to such time,
such conversion right will be lost (unless the Corporation defaults in the
payment of the Redemption Price).
 
     Any notice that is mailed as herein provided shall be conclusively presumed
to have been duly given, whether or not the holder of shares of Convertible
Preferred Stock receives such notice; and failure to give such notice by mail,
or any defect in such notice, to the holders of any shares designated for
redemption shall not affect the validity of the proceedings for the redemption
of any other shares of Convertible Preferred Stock. On or after the date fixed
for redemption as stated in such notice, each holder of the shares called for
redemption shall surrender the certificate evidencing such shares to the
Corporation at the place designated in such notice and shall thereupon be
entitled to receive payment of the Redemption Price. If less than all the shares
evidenced by any such surrendered certificate are redeemed, a new certificate
shall be issued evidencing the unredeemed shares.
 
     No fractional shares of Convertible Preferred Stock shall be issued upon
redemption of less than all Convertible Preferred Stock. If more than one
certificate evidencing shares of Convertible Preferred Stock shall be held at
one time by the same holder, the number of full shares issuable upon redemption
of less than all of such shares of Convertible Preferred Stock shall be computed
on the basis of the aggregate number of shares of Convertible Preferred Stock so
held. Instead of any fractional share of Convertible Preferred Stock that would
otherwise be issuable to a holder upon redemption of less than all shares of
Convertible Preferred Stock, the Corporation shall pay a cash adjustment in
respect of such fractional share in an amount equal to the same fraction of the
fair value per share of Convertible Preferred Stock (as determined in good faith
by the Board of Directors or in any manner prescribed by the Board of Directors)
at the close of business on the date fixed for redemption.
 
     Notice having been given as aforesaid, if, on the date fixed for
redemption, funds necessary for the redemption shall be available therefor and
shall have been deposited with a bank or trust corporation with irrevocable
instructions and authority to pay the Redemption Price to the holders of the
Convertible Preferred Stock, then, notwithstanding that the certificates
evidencing any shares so called for redemption shall not have been surrendered,
dividends with respect to the shares so called shall cease to accrue on and
after the date fixed for redemption, such shares shall no longer be deemed
outstanding, the holders thereof shall cease to be shareholders of the
Corporation and all rights whatsoever with respect to the shares so called for
redemption (except the right of the holders to receive the Redemption Price
without interest upon surrender of their certificates therefor) shall terminate.
If funds legally available for such purpose are not sufficient for redemption of
the shares of Convertible Preferred Stock which were to be redeemed, then the
certificates evidencing such shares shall be deemed not to be surrendered, such
shares shall remain outstanding, and the right of holders of shares of
Convertible Preferred Stock thereafter shall continue to be only those of a
holder of shares of the Convertible Preferred Stock.
 
     Upon an optional redemption by the Corporation, if at any time the
Corporation does not pay amounts sufficient to redeem all Convertible Preferred
Stock, then such funds which are paid shall be applied to redeem such shares of
Convertible Preferred Stock as the Corporation may designate by lot or in such
other manner as the Board of Directors may determine to be fair, or such
redemption shall be effected pro rata.
 
     The shares of Convertible Preferred Stock shall not be subject to the
operation of any mandatory purchase, retirement or sinking fund.
 
     Section VI.  Conversion Privilege.
 
     (a) Right of Conversion.  Each share of Convertible Preferred Stock shall
be convertible at the option of the holder thereof, at any time prior to 5:00
p.m. New York City time on the Business Day prior to the date
 
                                      VI-3

<PAGE>   167
 
fixed for redemption of such share as herein provided, into fully paid and
nonassessable shares of Common Stock, at the rate of that number of shares of
Common Stock for each full share of Convertible Preferred Stock that is equal to
$50 divided by the conversion price applicable per share of Common Stock, or
into such additional or other securities, cash or property and at such other
rates as required in accordance with the provisions of this Section VI. For
purposes of this resolution, the "conversion price" applicable per share of
Common Stock shall initially be equal to $50.065 and shall be adjusted from time
to time in accordance with the provisions of this Section VI.
 
     (b) Conversion Procedures.  Any holder of shares of Convertible Preferred
Stock desiring to convert such shares into Common Stock shall surrender the
certificate or certificates evidencing such shares of Convertible Preferred
Stock at the office of the transfer agent for the Convertible Preferred Stock,
which certificate or certificates, if the Corporation shall so require, shall be
duly endorsed to the Corporation or in blank, or accompanied by proper
instruments of transfer to the Corporation or in blank, accompanied by
irrevocable written notice to the Corporation that the holder elects so to
convert such shares of Convertible Preferred Stock and specifying the name or
names (with address or addresses) in which a certificate or certificates
evidencing shares of Common Stock are to be issued.
 
     No payments or adjustments in respect of dividends on shares of Convertible
Preferred Stock surrendered for conversion or on account of any dividend on the
Common Stock issued upon conversion shall be made upon the conversion of any
shares of Convertible Preferred Stock; provided, however, that:
 
          (i) if a dividend record date fixed for the Convertible Preferred
     Stock as established herein results in a holder who undertakes conversion
     being eligible to receive on any dividend payment date both a dividend on
     the Convertible Preferred Stock and a dividend on the Common Stock issued
     upon conversion thereof, then such holder shall be entitled to receive only
     the higher of such dividend amounts; and
 
          (ii) if the Corporation shall, by dividend or otherwise, declare or
     make a distribution on its Common Stock referred to in Section VI(c)(iv) or
     VI(c)(v) (including, without limitation, dividends or distributions
     referred to in the last sentence of Section VI(c)(iv)), the holder of each
     share of Convertible Preferred Stock, upon the conversion thereof
     subsequent to the close of business on the date fixed for the determination
     of shareholders entitled to receive such distribution and prior to the
     effectiveness of the conversion price adjustment in respect of such
     distribution, shall also be entitled to receive for each share of Common
     Stock into which such share of Convertible Preferred Stock is converted,
     the portion of the shares of Common Stock, rights, warrants, evidences of
     indebtedness, shares of capital stock, cash and assets so distributed
     applicable to one share of Common Stock; provided, however, that at the
     election of the Corporation (whose election shall be evidenced by a
     resolution of the Board of Directors) with respect to all holders so
     converting, the Corporation may, in lieu of distributing to such holder any
     portion of such distribution not consisting of cash or securities of the
     Corporation, pay such holder an amount in cash equal to the fair market
     value thereof (as determined in good faith by the Board of Directors, whose
     determination shall be conclusive and described in a resolution of the
     Board of Directors). If any conversion of a share of Convertible Preferred
     Stock described in the immediately preceding sentence occurs prior to the
     payment date for a distribution to holders of Common Stock which the holder
     of the share of Convertible Preferred Stock so converted is entitled to
     receive in accordance with the immediately preceding sentence, the
     Corporation may elect (such election to be evidenced by a resolution of the
     Board of Directors) to distribute to such holder a due bill for the shares
     of Common Stock, rights, warrants, evidences of indebtedness, shares of
     capital stock, cash or assets to which such holder is so entitled, provided
     that such due bill (i) meets any applicable requirements of the principal
     national securities exchange or other market on which the Common Stock is
     then traded and (ii) requires payment or delivery of such shares of Common
     Stock, rights, warrants, evidences of indebtedness, shares of capital
     stock, cash or assets no later than the date of payment or delivery thereof
     to holders of shares of Common Stock receiving such distribution.
 
     The Corporation shall, as soon as practicable after such deposit of
certificates evidencing shares of Convertible Preferred Stock accompanied by the
written notice and compliance with any other conditions
 
                                      VI-4

<PAGE>   168
 
herein contained, deliver at such office of such transfer agent to the person
for whose account such shares of Convertible Preferred Stock were so
surrendered, or to the nominee or nominees of such person, certificates
evidencing the number of full shares of Common Stock to which such person shall
be entitled as aforesaid, together with a cash adjustment in respect of any
fraction of a share of Common Stock as hereinafter provided. Such conversion
shall be deemed to have been made as of the date of such surrender of the shares
of Convertible Preferred Stock to be converted, and the person or persons
entitled to receive the Common Stock deliverable upon conversion of such
Convertible Preferred Stock shall be treated for all purposes as the record
holder or holders of such Common Stock on such date.
 
     (c) Adjustment of Conversion Price.  The conversion price at which a share
of Convertible Preferred Stock is convertible into Common Stock shall be subject
to adjustment from time to time as follows:
 
          (i) In case the Corporation shall pay or make a dividend or other
     distribution on its Common Stock exclusively in Common Stock or shall pay
     or make a dividend or other distribution on any other class or series of
     capital stock of the Corporation which dividend or distribution includes
     Common Stock, the conversion price in effect at the opening of business on
     the day following the date fixed for the determination of shareholders
     entitled to receive such dividend or other distribution shall be reduced by
     multiplying such conversion price by: A/(A + B), where:
 
        A = the number of shares of Common Stock outstanding at the close of
            business on the date fixed for such determination; and
 
        B = the total number of shares of Common Stock constituting such
            dividend or other distribution,
 
     such reduction to become effective immediately after the opening of
     business on the day following the date fixed for such determination. For
     purposes of this subparagraph (i), the number of shares of Common Stock at
     any time outstanding shall not include shares held in the treasury of the
     Corporation. The Corporation shall not pay any dividend or make any
     distribution on shares of Common Stock held in the treasury of the
     Corporation.
 
          (ii) In case the Corporation shall pay or make a dividend or other
     distribution on its Common Stock consisting exclusively of, or shall
     otherwise issue to all holders of its Common Stock, rights or warrants
     entitling the holders thereof to subscribe for or purchase shares of Common
     Stock at a price per share less than the Current Market Price Per Share of
     the Common Stock on the date fixed for the determination of shareholders
     entitled to receive such rights or warrants, the conversion price in effect
     at the opening of business on the day following the date fixed for such
     determination shall be reduced by multiplying such conversion price by:
     (A + B)/(A + C), where:
 
        A = the number of shares of Common Stock outstanding at the close of
            business on the date fixed for such determination,
 
        B = the number of shares of Common Stock which the aggregate of the
            offering price of the total number of shares of Common Stock so
            offered for subscription or purchase would purchase at such Current
            Market Price Per Share, and
 
        C = the number of shares of Common Stock so offered for subscription or
            purchase, such reduction to become effective immediately after the
            opening of business on the day following the date fixed for such
            determination.
 
     In case any rights or warrants referred to in this subparagraph (ii) in
     respect of which an adjustment shall have been made shall expire
     unexercised within 45 days after the shares shall have been distributed or
     issued by the Corporation the conversion price shall be readjusted at the
     time of such expiration to the conversion price that would have been in
     effect if no adjustment had been made on account of the distribution or
     issuance of such expired rights or warrants. For the purposes of this
     Section VI(c)(ii), if both (A) a Distribution Date (as defined in Section
     3(a) of the Rights Agreement) and (B) an event set forth in Section
     11(a)(ii) or 13(a) of the Rights Agreement shall have occurred, then the
     later to occur of such events shall be deemed to constitute an issuance of
     rights to purchase shares of the related common stock.
 
                                      VI-5

<PAGE>   169
 
          (iii) In case outstanding shares of Common Stock shall be subdivided
     into a greater number of shares of Common Stock, the conversion price in
     effect at the opening of business on the day following the day upon which
     such subdivision becomes effective shall be proportionately reduced, and
     conversely, in case outstanding shares of Common Stock shall be combined
     into a smaller number of shares of Common Stock, the conversion price in
     effect at the opening of business on the day following the day upon which
     such combination becomes effective shall be proportionately increased, such
     reduction or increase, as the case may be, to become effective immediately
     after the opening of business on the day following the day upon which such
     subdivision or combination becomes effective.
 
          (iv) In case the Corporation shall, by dividend or otherwise,
     distribute to all holders of its Common Stock evidences of its
     indebtedness, shares of any class or series of capital stock, cash or
     assets (including securities, but excluding any rights or warrants referred
     to in subparagraph (ii) of this Section VI(c), any dividend or distribution
     paid exclusively in cash and any dividend or distribution referred to in
     subparagraph (i) of this Section VI(c)), the conversion price shall be
     reduced so that the same shall equal the price determined by multiplying
     the conversion price in effect immediately prior to the effectiveness of
     the conversion price reduction contemplated by this subparagraph (iv) by:
     (A - B)/A, where:
 
        A = the Current Market Price Per Share of the Common Stock on the date
            fixed for the payment of such distribution (the "Reference Date"),
            and
 
        B = the fair market value (as determined in good faith by the Board of
            Directors, whose determination shall be conclusive and described in
            a resolution of the Board of Directors), on the Reference Date, of
            the portion of the evidence of indebtedness, shares of capital
            stock, cash and assets so distributed applicable to one share of
            Common Stock,
 
     such reduction to become effective immediately prior to the opening of
     business on the day following the Reference Date, provided, however, that
     for purposes of this subparagraph (iv), any dividend or distribution that
     includes shares of Common Stock or rights or warrants to subscribe for or
     purchase shares of Common Stock shall be deemed instead to be (1) a
     dividend or distribution of the evidences of indebtedness, cash, assets or
     shares of capital stock other than such shares of Common Stock or rights or
     warrants (making any further conversion price reduction required by this
     subparagraph (iv)) immediately followed by (2) a dividend or distribution
     of such shares of Common Stock or such rights or warrants (making any
     further conversion price reduction required by subparagraph (i) or (ii) of
     this Section VI(c), except (A) the Reference Date of such dividend or
     distribution as defined in this subparagraph (iv) shall be substituted as
     "the date fixed for the determination of shareholders entitled to receive
     such dividend or other distribution", "the date fixed for the determination
     of shareholders entitled to receive such rights or warrants" and "the date
     fixed for such determination" within the meaning of subparagraph (i) and
     (ii) of this Section VI(c) and (B) any shares of Common Stock included in
     such dividend or distribution shall not be deemed "outstanding at the close
     of business on the date fixed for such determination" within the meaning of
     subparagraph (i) of this Section VI(c)). If the Board of Directors
     determines the fair market value of any distribution for purposes of this
     subparagraph (iv) by reference to the actual or when issued trading market
     for any securities comprising such distribution, it must in doing so
     consider the prices in such market over the same period used in computing
     the Current Market Price Per Share of Common Stock.
 
          (v) In case the Corporation shall pay or make a dividend or other
     distribution on its Common Stock exclusively in cash (excluding (A) cash
     that is part of the distribution referred to in (iv) above and, (B) in the
     case of any quarterly cash dividend on the Common Stock, the portion
     thereof that does not exceed the per share amount of the next preceding
     quarterly cash dividend on the Common Stock (as adjusted to appropriately
     reflect any of the events referred to in subparagraph (i), (ii), (iii),
     (iv) and (v) of this Section VI(c)), or all of such quarterly cash dividend
     if the amount thereof per share amount of Common Stock multiplied by four
     does not exceed 15% of the Current Market Price Per Share of the Common
     Stock on the Trading Day next preceding the date of declaration of such
     dividend), the conversion price shall be reduced so that the same shall
     equal the conversion price in effect immediately
 
                                      VI-6

<PAGE>   170
 
     prior to the effectiveness of the conversion price reduction contemplated
     by this subparagraph (v) by: (A - B)/A, where:
 
        A = the Current Market Price Per Share of the Common Stock on the date
            fixed for the payment of such distribution, and
 
        B = the amount of cash so distributed and not excluded as provided above
            applicable to one share of Common Stock,
 
     such reduction to become effective immediately prior to the opening of
     business on the day following the date fixed for the payment of such
     distribution.
 
          (vi) No adjustment in the conversion price shall be required unless
     such adjustment would require an increase or decrease of at least 1% in the
     conversion price; provided, however, that any adjustments which by reason
     of this subparagraph (vi) are not required to be made shall be carried
     forward and taken into account in any subsequent adjustment.
 
          (vii) Whenever the conversion price is adjusted as herein provided:
     (1) the Corporation shall compute the adjusted conversion price and shall
     prepare a certificate signed by the Treasurer of the Corporation setting
     forth the adjusted conversion price and showing in reasonable detail the
     facts upon which such adjustment in based, and such certificate shall
     forthwith be filed with the transfer agent for the Convertible Preferred
     Stock; and (2) a notice stating that the conversion price has been adjusted
     and setting forth the adjusted conversion price shall forthwith be
     required, and as soon as practicable after it is required, such notice
     shall be mailed by the Corporation to all record holders of shares of
     Convertible Preferred Stock at their last addresses as they shall appear
     upon the stock transfer books of the Corporation.
 
          (viii) The Corporation from time to time may reduce the conversion
     price by any amount for any period of time if the period is at least twenty
     days, the reduction is irrevocable during the period and the Board of
     Directors of the Corporation shall have made a determination that such
     reduction would be in the best interest of the Corporation, which
     determination shall be conclusive. Whenever the conversion price is reduced
     pursuant to the preceding sentence, the Corporation shall mail to holders
     of record of the Convertible Preferred Stock a notice of the reduction at
     least fifteen days prior to the date the reduced conversion price takes
     effect, and such notice shall state the reduced conversion price and the
     period it will be in effect.
 
     (d) No Fractional Shares.  No fractional shares of Common Stock shall be
issued upon conversion of Convertible Preferred Stock. If more than one
certificate evidencing shares of Convertible Preferred Stock shall be
surrendered for conversion at one time by the same holder, the number of full
shares issuable upon conversion thereof shall be computed on the basis of the
aggregate number of shares of Convertible Preferred Stock so surrendered.
Instead of any fractional share of Common Stock that would otherwise be issuable
to a holder upon conversion of any shares of Convertible Preferred Stock, the
Corporation shall pay a cash adjustment in respect of such fractional share in
an amount equal to the same fraction of the market price per share of Common
Stock (as determined by the Board of Directors or in any manner prescribed by
the Board of Directors, which, so long as the Common Stock is listed on the New
York Stock Exchange or quoted on the Nasdaq National Market System, shall be the
reported last sale price regular way) at the close of business on the day of
conversion.
 
     (e) Reclassification, Consolidation, Merger or Sale of Assets.  In the
event that the Corporation shall be a party to any transaction (including
without limitation any recapitalization or reclassification of the Common Stock
(other than a change in par value, or from par value to no par value, or from no
par value to par value, or as a result of a subdivision or combination of the
Common Stock), any consolidation of the Corporation with, or merger of the
Corporation into, any other person, any merger of another person into the
Corporation (other than a merger which does not result in a reclassification,
conversion, exchange or cancellation of outstanding shares of Common Stock of
the Corporation), any sale or transfer of all or substantially all of the assets
of the Corporation or any share exchange) pursuant to which the Common Stock is
converted into the right to receive other securities, cash or other property,
then lawful provisions shall be made as part of the terms of
 
                                      VI-7

<PAGE>   171
 
such transaction whereby the holder of each share of Convertible Preferred Stock
then outstanding shall have the right thereafter to convert such share only into
(i) in the case of any such transaction other than a Common Stock Fundamental
Change and subject to funds being legally available for such purpose under
applicable law at the time of such conversion, the kind and amount of
securities, cash and other property receivable upon such transaction by a holder
of the number of shares of Common Stock of the Corporation into which such share
of Convertible Preferred Stock might have been converted immediately prior to
such transaction, after giving effect, in the case of any Non-Stock Fundamental
Change, to any adjustment in the conversion price required by the provisions of
Section VI(h), and (ii) in the case of a Common Stock Fundamental Change, common
stock of the kind received by holders of Common Stock as a result of such Common
Stock Fundamental Change in an amount determined pursuant to the provisions of
Section VI(h). The Corporation or the person formed by such consolidation or
resulting from such merger or which acquires such assets or which acquires the
Corporation's shares, as the case may be, shall make provisions in its
certificate or articles of incorporation or other constituent document to
establish such right. Such certificate or articles of incorporation or other
constituent document shall provide for adjustments which, for events subsequent
to the effective date of such certificate or articles of incorporation or other
constituent document, shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Section VI. The above provisions shall
similarly apply to successive transactions of the foregoing type.
 
     (f) Reservation of Shares; Etc.  The Corporation shall at all times reserve
and keep available, free from preemptive rights out of its authorized and
unissued stock, solely for the purpose of effecting the conversion of the
Convertible Preferred Stock, such number of shares of its Common Stock as shall
from time to time be sufficient to effect that conversion of all shares of
Convertible Preferred Stock from time to time outstanding. The Corporation shall
from time to time, in accordance with the laws of the State of Florida, in good
faith and as expeditiously as possible endeavor to cause the authorized number
of shares of Common Stock to be increased if at any time the number of shares of
authorized and unissued Common Stock shall not be sufficient to permit the
conversion of all the then-outstanding shares of Convertible Preferred Stock.
 
     If any shares of Common Stock required to be reserved for purposes of
conversion of the Convertible Preferred Stock hereunder require registration
with or approval of any governmental authority under any Federal or State law
before such shares may be issued upon conversion, the Corporation will in good
faith and as expeditiously as possible endeavor to cause such shares to be duly
registered or approved as the case may be. If the Common Stock is listed on the
New York Stock Exchange or any other national securities exchange or traded
through the Nasdaq National Market, the Corporation will, if permitted by the
rules of such exchange or market, list and keep listed on such exchange or make
and keep eligible for trading on such market (as the case may be), upon official
notice of issuance, all shares of Common Stock issuable upon conversion of the
Convertible Preferred Stock; provided, however, that such shares of Common Stock
may be delisted from such exchange or may cease to be eligible for trading
through such market (as the case may be) if, prior to or concurrent with such
delisting or cessation of eligibility for trading, the Corporation causes such
shares of Common Stock to be listed on or eligible for trading through any other
such exchange or market.
 
     (g) Prior Notice of Certain Events.  In case:
 
          (i) the Corporation shall (1) declare any dividend (or any other
     distribution) on its Common Stock, other than (A) a dividend payable in
     shares of Common Stock or (B) a dividend payable in cash out of its
     retained earnings other than any special or nonrecurring or other
     extraordinary dividend or (2) declare or authorize a redemption or
     repurchase of in excess of 10% of the then-outstanding shares of Common
     Stock; or
 
          (ii) the Corporation shall authorize the granting to all holders of
     Common Stock of rights or warrants to subscribe for or purchase any shares
     of stock of any class or series or of any other rights or warrants; or
 
          (iii) of any reclassification of Common Stock (other than a
     subdivision or combination of the outstanding Common Stock, or a change in
     par value, or from par value to no par value, or from no par value to par
     value), or of any consolidation or merger to which the Corporation is a
     party and for which approval of any shareholders of the Corporation shall
     be required, or of the sale or transfer of all or
 
                                      VI-8

<PAGE>   172
 
     substantially all of the assets of the Corporation or of any share exchange
     whereby the Common Stock is converted into other securities, cash or other
     property; or
 
          (iv) of the voluntary or involuntary dissolution, liquidation or
     winding up of the Corporation;
 
then the Corporation shall cause to be filed with the transfer agent for the
Convertible Preferred Stock, and shall cause to be mailed to the holders of
record of the Convertible Preferred Stock, at their last addresses as they shall
appear upon the stock transfer books of the Corporation, at least ten days prior
to the applicable record or effective date hereinafter specified, a notice
stating (x) the date on which a record (if any) is to be taken for the purpose
of such dividend, distribution, redemption, repurchase, rights or warrants or,
if a record is not to be taken, the date as of which the holders of Common Stock
of record to be entitled to such dividend, distribution, redemption, rights or
warrants are to be determined or (y) the date on which such reclassification,
consolidation, merger, sale, transfer, share exchange, dissolution, liquidation
or winding up is expected to become effective and the date as of which it is
expected that holders of Common Stock of record shall be entitled to exchange
their shares of Common Stock for securities, cash or other property deliverable
upon such reclassification, consolidation, merger, sale, transfer, share
exchange, dissolution, liquidation or winding up (but no failure to mail such
notice or any defect therein or in the mailing thereof shall affect the validity
of the corporate action required to be specified in such notice).
 
     (h) Adjustments in Case of Fundamental Changes.  Notwithstanding any other
provision in this Section VI to the contrary, if any Fundamental Change occurs,
then the conversion price in effect will be adjusted immediately after such
Fundamental Change as described below. In addition, in the event of a Common
Stock Fundamental Change, each share of Convertible Preferred Stock shall be
convertible solely into common stock of the kind received by holders of Common
Stock as the result of such Common Stock Fundamental Change.
 
     For purposes of calculating any adjustment to be made pursuant to this
Section VI(h) in the event of a Fundamental Change, immediately after such
Fundamental Change:
 
          (i) In the case of a Non-Stock Fundamental Change, the conversion
     price of the Convertible Preferred Stock shall thereupon become the lower
     of (1) the conversion price in effect immediately prior to such Non-Stock
     Fundamental Change, but after giving effect to any other prior adjustments
     effected pursuant to this Section VI, and (2) the result of A x $50/B,
     where:
 
        A = the greater of the Applicable Price or the then applicable Reference
Market Price, and
 
        B = (x) the then-current Redemption Price per share of Convertible
            Preferred Stock or (y) for any Non-Stock Fundamental Change that
            occurs before the Convertible Preferred Stock becomes redeemable by
            the Corporation pursuant to Section V, the applicable price per
            share set forth for the date of such Non-Stock Fundamental Change in
            the following table:
 

<TABLE>
<CAPTION>
                        DATE OF NON-STOCK FUNDAMENTAL CHANGE                  PRICE
        --------------------------------------------------------------------  ------
        <S>                                                                   <C>
        After date of original issuance of Convertible Preferred Stock and
          on or before August 6, 1997.......................................  $53.13
        After August 7, 1997 and on or before August 6, 1998................  $52.81
        After August 7, 1998 and on or before August 6, 1999................  $52.50
        After August 7, 1999 and on or before August 6, 2000................  $52.19
</TABLE>

 
     plus, in any case referred to in this clause (y), an amount equal to all
     per share dividends on the Convertible Preferred Stock accrued and unpaid
     thereon, whether or not declared, to but excluding the date of such
     Non-Stock Fundamental Change; and
 
          (ii) In the case of a Common Stock Fundamental Change, the conversion
     price of the Convertible Preferred Stock in effect immediately prior to
     such Common Stock Fundamental Change, but after giving effect to any other
     prior adjustments effected pursuant to this Section VI, shall thereupon be
     adjusted by multiplying such conversion price by a fraction of which the
     numerator shall be the Purchaser Stock Price and the denominator shall be
     the Applicable Price; provided, however, that in the event of a Common
     Stock Fundamental Change in which (A) 100% by value of the consideration
     received by a holder of Common Stock is common stock of the successor,
     acquiror or other third party (and cash, if
 
                                      VI-9

<PAGE>   173
 
     any, is paid with respect to any fractional interests in such common stock
     resulting from such Common Stock Fundamental Change) and (B) all of the
     Common Stock shall have been exchanged for, converted into or acquired for
     common stock (and cash with respect to fractional interests) of the
     successor, acquiror or other third party, the conversion price of the
     Convertible Preferred Stock in effect immediately prior to such Common
     Stock Fundamental Change shall thereupon be adjusted by dividing such
     conversion price by the number of shares of common stock of the successor,
     acquiror, or other third party received by a holder of one share of Common
     Stock as a result of such Common Stock Fundamental Change.
 
     (i) Dividend or Interest Reinvestment Plans.  Notwithstanding the foregoing
provisions, the issuance of any shares of Common Stock pursuant to any plan
providing for the reinvestment of dividends or interest payable on securities of
the Corporation and the investment of additional optional amounts in shares of
Common Stock under any such plan, and the issuance of any shares of Common Stock
or options or rights to purchase such shares pursuant to any employee benefit
plan or program of the Corporation or pursuant to any option, warrant, right or
exercisable, exchangeable or convertible security outstanding as of the date the
Convertible Preferred Stock was first designated (except as expressly provided
in Section VI(c)(ii) with respect to certain events under the Rights Agreement),
and any issuance of Rights, shall not be deemed to constitute an issuance of
Common Stock or exercisable, exchangeable or convertible securities by the
Corporation to which any of the adjustment provisions described above applies.
There shall also be no adjustment of the conversion price in case of the
issuance of any stock (or securities convertible into or exchangeable for stock)
of the Corporation except as specifically described in this Section VI. If any
action would require adjustment of the conversion price pursuant to more than
one of the provisions described above, only one adjustment shall be made and
such adjustment shall be the amount of adjustment which has the highest absolute
value to holders of Convertible Preferred Stock.
 
     (j) Series A Preferred Stock Purchase Rights.  So long as Rights are
attached to the outstanding shares of Common Stock of the Corporation, each
share of Common Stock issued upon conversion of the shares of Convertible
Preferred Stock prior to the earliest of any Distribution Date (as defined in
Section 3(a) of the Rights Agreement), the date of redemption of the Rights or
the date of expiration of the Rights shall be issued with Rights in an amount
equal to the amount of Rights then attached to each such outstanding share of
Common Stock.
 
     Section VII.  Voting Rights.
 
     (a) General.  The holders of shares of Convertible Preferred Stock shall
not have any voting rights except as set forth below or as otherwise from time
to time required by law. In connection with any right to vote, each holder of a
share of Convertible Preferred Stock shall have one vote for each share held.
Any shares of Convertible Preferred Stock owned, directly or indirectly, by any
entity of which the Corporation owns, directly or indirectly, a majority of the
shares entitled to vote for directors, shall not have voting rights hereunder
and shall not be counted in determining the presence of a quorum.
 
     So long as any shares of the Corporation's Convertible Preferred Stock are
outstanding, the Corporation will not, without the affirmative vote or consent
of the holders of at least 66 2/3% of the outstanding shares of Convertible
Preferred Stock and outstanding Parity Dividend Stock, voting or consenting (as
the case may be) as a single class (i) amend, alter or repeal (by merger or
otherwise) any provision of the Corporation's Third Amended and Restated
Articles of Incorporation, as may be amended or restated from time to time, or
the by-laws so as to affect adversely the relative rights, preferences,
qualifications, limitations or restrictions of the Convertible Preferred Stock
or (ii) effect any reclassification of the Convertible Preferred Stock.
 
     (b) Default Voting Rights.  Notwithstanding any other provision of the
Corporation's Third Amended and Restated Articles of Incorporation, whenever
dividends on the Convertible Preferred Stock or any other class or series of
Parity Dividend Stock shall be in arrears in an aggregate amount equal to at
least six quarterly dividends (whether or not consecutive), (i) the number of
members of the Board of Directors of the Corporation shall be increased by two,
effective as the time of election of such directors as hereinafter provided and
(ii) the holders of shares of Convertible Preferred Stock (voting separately as
a class with all other affected classes or series of Parity Dividend Stock upon
which like voting rights have been conferred and are exercisable) shall have the
exclusive right to vote for and elect such two additional directors of the
 
                                      VI-10

<PAGE>   174
 
Corporation who shall continue to serve during the period such dividends remain
in arrears. The right of the holders of shares of Convertible Preferred Stock to
vote for such two additional directors shall terminate when all accrued and
unpaid dividends on the Convertible Preferred Stock and all other affected
classes or series of Parity Dividend Stock have been declared and paid or set
apart for payment. The term of office of all directors so elected shall
terminate immediately upon the termination of the right of the holders of shares
of Convertible Preferred Stock and such Parity Dividend Stock to vote for such
two additional directors, and the number of directors of the Board of Directors
of the Corporation shall immediately thereafter be reduced by two.
 
     The foregoing right of the holders of shares of Convertible Preferred Stock
with respect to the election of two directors may be exercised at any annual
meeting of shareholders or at any special meeting of shareholders held for such
purpose. If the right to elect directors shall have accrued to the holders of
shares of Convertible Preferred Stock more than ninety days preceding the date
established for the next annual meeting of stockholders, the President of the
Corporation shall, within twenty days after the delivery to the Corporation at
its principal office of a written request for a special meeting signed by the
holders of at least 10% of all outstanding shares of Convertible Preferred
Stock, call a special meeting of the holders of Convertible Preferred Stock to
be held within sixty days after the delivery of such request for the purpose of
electing such additional directors.
 
     Notwithstanding any other provision of the Corporation's Third Amended and
Restated Articles of Incorporation, the holders of shares of Convertible
Preferred Stock and any Parity Dividend Stock referred to above voting as a
class shall have the right to remove, without cause and at any time, and replace
any directors such holders shall have elected pursuant to this Section VII.
 
     Section VIII.  Outstanding Shares.  For purposes of this amendment, all
shares of Convertible Preferred Stock issued by the Corporation shall be deemed
outstanding except (i) from the date fixed for redemption pursuant to Section V,
all shares of Convertible Preferred Stock that have been so called for
redemption under Section V, to the extent provided thereunder; (ii) from the
date of surrender of certificates evidencing shares of Convertible Preferred
Stock, all shares of Convertible Preferred Stock converted into Common Stock;
and (iii) from the date of registration of transfer, all shares of Convertible
Preferred Stock owned, directly or indirectly, by any entity of which the
Corporation owns, directly or indirectly, a majority of the shares entitled to
vote for directors.
 
     Section IX.  Miscellaneous.
 
     (a) Whenever possible, each provision hereof shall be interpreted in a
manner as to be effective and valid under applicable law, but if any provision
hereof is held to be prohibited by or invalid under applicable law, such
provision shall be ineffective only to the extent of such prohibition or
invalidity, without invalidating or otherwise adversely affecting the remaining
provisions hereof. If a court of competent jurisdiction should determine that a
provision hereof would be valid or enforceable if a period of time were extended
or shortened or a particular percentage were increased or decreased, then such
court may make such change as shall be necessary to render the provision in
question effective and valid under applicable law.
 
     (b) The Corporation shall pay any and all stock transfer and documentary
stamp taxes that may be payable in request of any issuance or delivery of shares
of Convertible Preferred Stock or shares of Common Stock or other securities
issued on account of Convertible Preferred Stock pursuant hereto or certificates
or instruments evidencing such shares or securities. The Corporation shall not,
however, be required to pay any such tax which may be payable in respect of any
transfer involved in the issuance or delivery of shares of Convertible Preferred
Stock or Common Stock or other securities in a name other than that in which the
shares of Convertible Preferred Stock with respect to which such shares or other
securities are issued or delivered were registered, or in respect of any payment
to any person with respect to any such shares or securities other than a payment
to the registered holder thereof, and shall not be required to make any such
issuance, delivery or payment unless and until the person otherwise entitled to
such issuance, delivery or payment has paid to the Corporation the amount of any
such tax or has established, to the satisfaction of the Corporation, that such
tax has been paid or is not payable.
 
                                      VI-11

<PAGE>   175
 
     (c) In the event that a holder of shares of Convertible Preferred Stock
shall not by written notice designate the name in which shares of Common Stock
to be issued upon conversion of such shares should be registered or to whom
payment upon redemption of shares of Convertible Preferred Stock should be made
or the address to which the certificates or instruments evidencing such shares
or such payment should be sent, the Corporation shall be entitled to register
such shares and make such payment, in the name of the holder of such Convertible
Preferred Stock as shown on the records of the Corporation and to send the
certificates or instruments evidencing such shares or such payment, to the
address of such holder shown on the records of the Corporation.
 
     Section X.  Definitions.  The following definitions shall apply to terms
used in connection with the Convertible Preferred Stock:
 
     a. "Applicable Price" shall mean (i) in the event of a Non-Stock
Fundamental Change in which the holders of the Common Stock receive only cash,
the amount of cash received by the holder of one share of Common Stock and (ii)
in the event of any other Non-Stock Fundamental Change or any Common Stock
Fundamental Change, the average of the daily Closing Prices of the Common Stock
for the ten consecutive Trading Days prior to and including the record date for
the determination of the holders of Common Stock entitled to receive cash,
securities, property or other assets in connection with such Non-Stock
Fundamental Change or Common Stock Fundamental Change, or, if there is no such
record date, the date upon which the holders of the Common Stock shall have the
right to receive such cash, securities, property or other assets, in each case,
as adjusted in good faith by the Board of Directors of the Corporation to
appropriately reflect any of the events referred to in subparagraphs (i), (ii),
(iii), (iv) and (v) of Section VI(c).
 
     b. "Business Day" shall mean any day other than a Saturday, Sunday or any
day on which banking institutions are authorized to close in New York, New York.
 
     c. "Closing Price" of any common stock on any day shall mean the last
reported sale price regular way on such day or, in case no such sale takes place
on such day, the average of the reported closing bid and asked prices regular
way of the common stock in each case on the New York Stock Exchange, or, if the
common stock is not listed or admitted to trading on such Exchange, on the
principal national securities exchange or quotation system on which the common
stock is listed or admitted to trading or quoted, or, if not listed or admitted
to trading or quoted on any national securities exchange or quotation system,
the average of the closing bid and asked prices of the common stock in the
over-the-counter market on the day in question as reported by the National
Quotation Bureau Incorporated, or a similarly generally accepted reporting
service, or, if not so available in such manner, as furnished by any New York
Stock Exchange member firm selected from time to time by the Board of Directors
of the Corporation for that purpose.
 
     d. "Common Stock" shall mean the Corporation's now or hereafter issued
Common Stock.
 
     e. "Common Stock Fundamental Change" shall mean any Fundamental Change in

Stock consists of common stock that for each of the ten consecutive Trading Days
referred to with respect to such Fundamental Change in Section X(a) above has
been admitted for listing or admitted for listing subject to notice of issuance
on a national securities exchange or quoted on the Nasdaq National Market;
provided, however, that a Fundamental Change shall not be a Common Stock
Fundamental Change unless either (i) the Corporation continues to exist after
the occurrence of such Fundamental Change and the outstanding shares of
Convertible Preferred Stock continue to exist as outstanding shares of
Convertible Preferred Stock, or (ii) not later than the occurrence of such
Fundamental Change, the outstanding shares of Convertible Preferred Stock are
converted into or exchanged for shares of convertible preferred stock of a
corporation succeeding to the business of the Corporation, which Convertible
Preferred Stock has powers, preferences and relative, participating, optional or
other rights, and qualifications, limitations and restrictions, substantially
similar to those of the Convertible Preferred Stock.
 
                                      VI-12

<PAGE>   176
 
     f. "Current Market Price Per Share" shall mean, as to the Common Stock on
any date in question, the average of the daily Closing Prices for the five
consecutive Trading Days prior to and including the date in question; provided,
however, that:
 
          (1) if the Ex Date for any event (other than the issuance or
     distribution requiring such computation) that required an adjustment to the
     conversion price pursuant to subparagraphs (i), (ii), (iii), (iv), or (v)
     of Section VI(c) ("Other Event") occurs after the fifth Trading Day prior
     to the day in question and prior to the Ex Date for the issuance or
     distribution requiring such computation (the "Current Event"), the Closing
     Price for each Trading Day prior to the Ex Date for such Other Event shall
     be adjusted by multiplying such Closing Price by the same fraction by which
     the conversion price is so required to be adjusted as a result of such
     Other Event,
 
          (2) if the Ex Date for any Other Event occurs after the Ex Date for
     the Current Event and on or prior to the date in question, the Closing
     Price for each Trading Day on and after the Ex Date for such Other Event
     shall be adjusted by multiplying such Closing Price by the reciprocal of
     the fraction by which the conversion price is so required to be adjusted as
     a result of such Other Event,
 
          (3) if the Ex Date for any Other Event occurs on the Ex Date for the
     Current Event, one of those events, as determined by the Corporation, shall
     be deemed for purposes of clauses (1) and (2) of this proviso to have an Ex
     Date occurring prior to the Ex Date for the other of those events, and
 
          (4) if the Ex Date for the Current Event is on or prior to the date in
     question, then after taking into account any adjustment required pursuant
     to clause (2) of this proviso, the Closing Price for each Trading Day on or
     after such Ex Date shall be adjusted by adding thereto the amount of any
     cash and the fair market value on the date in question (as determined in
     good faith by the Board of Directors in a manner consistent with any
     determination of such value for purposes of paragraph (iv) or (v) of
     Section VI(c), whose determination shall be conclusive and described in a
     resolution of the Board of Directors) of the portion of the rights,
     warrants, evidences of indebtedness, shares of capital stock or assets
     being distributed applicable to one share of Common Stock.
 
     g. "Ex Date" shall mean (1) when used with respect to any issuance or
distribution, means the first date on which the Common Stock trades regular way
on the relevant exchange or in the relevant market from which the Closing Price
was obtained without the right to receive such issuance or distribution and (2)
when used with respect to any subdivision or combination of shares of Common
Stock, means the first date on which the Common Stock trades regular way on such
exchange or in such market after the time at which such subdivision or
combination becomes effective.
 
     h. "Fundamental Change" shall mean the occurrence of any transaction or
event in connection with a plan pursuant to which all or substantially all of
the Common Stock shall be exchanged for, converted into, or acquired for or
constitute solely the right to receive cash, securities, property or other
assets (whether by means of an exchange offer, liquidation, tender offer,
consolidation, merger, combination, reclassification, recapitalization or
otherwise); provided, however, in the case of a plan involving more than one
such transaction or event, for purposes of adjustment of the conversion price,
such Fundamental Change shall be deemed to have occurred when substantially all
of the Common Stock of the Corporation shall be exchanged for, converted into,
or acquired for or constitute solely the right to receive cash, securities,
property or other assets, but the adjustment shall be based upon the highest
weighted average of consideration per share which a holder of Common Stock could
have received in such transactions or events as a result of which more than 50%
of the Common Stock of the Corporation shall have been exchanged for, converted
into, or acquired for or constitute solely the right to receive cash,
securities, property or other assets.
 
     i. "Junior Dividend Stock" shall mean the Junior Stock and any other
capital stock of the Corporation ranking junior as to dividends to the
Convertible Preferred Stock.
 
     j. "Junior Liquidation Stock" shall mean the Junior Stock and any other
class or series of the Corporation's capital stock ranking junior to the
Convertible Preferred Stock as to distributions of assets upon liquidation,
dissolution or winding up of the Corporation, whether voluntary or involuntary.

Stock, and the Corporation's hereafter issued capital stock ranking junior to
the Convertible Preferred Stock both as to the payment of
 
                                      VI-13

Board of Directors
American Bankers Insurance Group, Inc.
11222 Quail Roost Drive
Miami, Florida 33157
 
Attention: Mr. R. Kirk Landon, Chairman
 
Dear Members of the Board:
 
     On behalf of Cendant Corporation we are pleased to submit a proposal to
acquire American Bankers Insurance Group, Inc. for $58 per common share payable
in cash and stock. Our proposal, representing a premium of $11 (in excess of
23%) over the value of American International Group's proposal, is demonstrably
superior to the AIG proposed transaction.
 
     Several months ago one of our senior executives had discussed with Mr.
Gaston our interest in pursuing a business combination with American Bankers. As
recently as December, in response to our inquiry as to whether American Bankers
was engaged in discussions relating to an acquisition and to our expression of
Cendant's strong interest in exploring such a transaction with American Bankers,
Mr. Gaston said that American Bankers was not pursuing any acquisition
transaction, and suggested that he meet with our senior executive in early
January to discuss the matter further. In view of this, it is particularly
disappointing that we were not made aware that American Bankers was interested
in pursuing acquisition proposals and, accordingly, we did not have the
opportunity to submit an offer prior to the announcement of your proposed
transaction with AIG.
 
     We would have liked to discuss our proposal directly with you. However, the
terms of Section 6.2 of your agreement with AIG purport to prohibit discussions
with us or any other party until 120 days following the date of such agreement,
at which time, as both you and AIG have publicly stated, the acquisition of
American Bankers by AIG likely will have been completed, making any discussions
between us irrelevant. We believe this is an extraordinary measure and raises
questions about whether it is in the best interests of American Bankers'
shareholders.
 
     Accordingly, we will be commencing promptly a cash tender offer directly to
American Bankers' shareholders for 51% of American Bankers' shares at a price of
$58 per common share to be followed by a second step merger in which shares of
Cendant common stock with a fixed value of $58 per share will be exchanged on a
tax-free basis for the balance of American Bankers' common stock and each share
of American Bankers' preferred stock will be converted into one share of Cendant
preferred stock having substantially similar terms, except that such shares will
be convertible into shares of Cendant common stock calculated in accordance with
the terms of the American Bankers' preferred stock.
 
     The provisions in your agreement with AIG include highly unusual and
restrictive conditions which, in fact, represent a virtual forfeiture of the
Board's fundamental mandate of protecting the interests of shareholders.
Accordingly, we have today commenced litigation in federal court in Miami to
ensure that your shareholders will have the opportunity to consider our offer
and to assist your board in fulfilling its fiduciary obligations and to resolve
certain other issues.
 
     Although we have determined that it is both necessary and appropriate,
under the circumstances, to commence our cash tender offer and litigation, our
strong preference would be to enter into a merger agreement with you containing
substantially the same terms and conditions (other than price and inappropriate
terms) as your proposed transaction with AIG.
 
     In addition to its significant economic superiority, the merits and the
strategic value of the combination of Cendant and American Bankers are
compelling. Cendant (NYSE:CD) is the product of the recent combination of CUC
International Inc. and HFS Incorporated, creating the world's largest consumer
and business services company. Cendant interacts with approximately 170 million
customers and members around the world, several times each year. Cendant is
investment grade rated and has a market value of approximately
 
                                      VII-1

<PAGE>   180
 
$30 billion. Cendant's 1997 revenues and net income are estimated by Wall Street
analysts at approximately $5.1 billion and $900 million, respectively. Cendant
has recently announced its acquisition of Providian Direct, a direct marketer of
automobile insurance. Under separate cover, we have sent a copy of the proxy
statement for the merger that created Cendant.
 
     Cendant's vision for American Bankers is one of exceptional growth and
opportunity, which involves utilizing Cendant's distribution channels and
customer base as an outlet for American Bankers' products and capitalizing on
American Bankers' existing relationships with financial institutions and
retailers to increase penetration of Cendant's products. Consistent with this
vision, and Cendant's past strategic acquisition practices, Cendant would expect
American Bankers' management to continue with the company, would not expect
significant employment reductions and would expect American Bankers to continue
to maintain its headquarters in Miami.
 
     The price we are offering in our proposal clearly provides significantly
greater value to your shareholders than the proposed transaction with AIG. It
would also benefit Cendant's shareholders and be accretive to earnings within
the first year. Our proposal is not subject to any due diligence or financing
condition and the funds for the cash portion of our offer are available from
existing cash resources and under our credit facilities. In addition, Cendant,
having acquired control of insurers in the past, is extremely familiar with the
insurance regulatory process, has obtained approvals of the type required to
implement this proposal and will be able to complete our proposed transaction on
a timely basis.
 
     Accordingly, we strongly believe that you are obligated by principles of
fiduciary duty to consider and accept our proposal. Consistent with your clear
fiduciary duties, we expect you will provide us with at least the same
information you furnished to AIG in the course of your discussions and
negotiations with them and that you will discuss and negotiate with us the
details of our proposal. In addition, you should take whatever other actions are
reasonably necessary or appropriate so that we may operate on a level playing
field with AIG and any other companies which may be interested in acquiring
American Bankers.
 
     Our Board of Directors is fully supportive of our proposal and has
unanimously authorized and approved it and no other Cendant approval is required
for this transaction. Consistent with our Board of Directors' action, we and our
advisors stand ready to meet with you and your advisors at your earliest
convenience. We want to stress that we are flexible as to all aspects of our
proposal and are anxious to proceed to discuss and negotiate it with you as soon
as possible.
 
     Should you find it helpful to do so in connection with reviewing and
considering our proposal, you and your advisors should feel free to contact our
outside advisors: Steven B. Wolitzer of Lehman Brothers and Jack Levy of Merrill
Lynch & Co., our financial advisors, and David Fox of Skadden, Arps, Slate,
Meagher & Flom LLP, our legal counsel.
 
     Personally and on behalf of our colleagues at Cendant, we look forward to
hearing from you soon and working with you on our proposal.

                                    PART II
 
                   INFORMATION NOT REQUIRED IN THE PROSPECTUS
 
ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     The Restated Certificate of Incorporation of AIG (the "Certificate")
provides that AIG shall indemnify to the full extent permitted by law any person
made, or threatened to be made, a party to an action, suit or proceeding
(whether civil, criminal, administrative or investigative) by reason of the fact
that he, his testator or intestate is or was a director, officer or employee of
AIG or serves or served any other enterprise at the request of AIG. Section 6.4
of AIG's By-Laws contains a similar provision.
 
     The Certificate also provides that a director will not be personally liable
to AIG or its stockholders for monetary damages for breach of fiduciary duty as
a director, except to the extent that such an exemption from liability or
limitation thereof is not permitted by the Delaware General Corporation Law (the
"DGCL").
 
     Section 145 of the DGCL permits indemnification against expenses, fines,
judgment and settlements incurred by any director, officer or employee of a
company in the event of pending or threatened civil, criminal, administrative or
investigative proceedings, if such person was, or was threatened to be made, a
party by reason of the fact that he is or was a director, officer or employee of
the company. Section 145 also provides that the indemnification provided for
therein shall not be deemed exclusive of any other rights to which those seeking
indemnification may otherwise be entitled. In addition, AIG and its subsidiaries
maintain a directors' and officers' liability insurance policy.
 
ITEM 21(A).  EXHIBITS
 
     See Exhibit Index.
 
ITEM 21(B).  FINANCIAL STATEMENT SCHEDULES
 
     All financial statement schedules of AIG and American Bankers which are
required to be included herein are included in the Annual Report of AIG on Form
10-K for the fiscal year ended December 31, 1996 (File No. 1-8787) or the Annual
Report of American Bankers on Form 10-K for the fiscal year ended December 31,
1996 (File No. 0-9633), respectively, which are incorporated herein by
reference.
 
ITEM 22.  UNDERTAKINGS
 
     1. Insofar as indemnification for liabilities arising under the Securities
Act of 1933 (the "Securities Act") may be permitted to directors, officers and
controlling persons of the registrant pursuant to the foregoing provisions, or
otherwise, the registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Securities Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question of whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.
 
     2. The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
 
                                      II-1

<PAGE>   182
 
     3. The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11 or 13 of this form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.
 
     4. The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.
 
     5. The undersigned registrant hereby undertakes:
 
          (a) To file, during any period in which offers and sales are being
     made, a post-effective amendment to this registration statement:
 
             (i) To include any prospectus required by Section 10(a)(3) of the
        Securities Act;
 
             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of the registration statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the registration statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high and of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424(b) if, in the aggregate, the
        changes in volume and price represent no more than 20 percent change in
        the maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective registration statement;
 
             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in the registration statement
        or any material change to such information in the registration
        statement;
 
provided, however, that paragraphs 5(a)(i) and 5(a)(ii) do not apply if the
registration statement is on Form S-3, Form S-8 or Form F-3, and the information
required to be included in a post-effective amendment by those paragraphs is
contained in periodic reports filed with or furnished to the Commission by the
registrant pursuant to Section 13 or 15(d) of the Exchange Act that are
incorporated by reference in the registration statement.
 
          (b) That for the purposes of determining any liability under the
     Securities Act, each such post-effective amendment shall be deemed to be a
     new registration statement relating to the securities offered therein, and
     the offering of such securities at that time shall be deemed to be the
     initial bona fide offering thereof.
 
          (c) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.
 
     6. The undersigned registrant hereby undertakes as follows: that prior to
any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.
 
     7. The registrant undertakes that every prospectus: (i) that is filed
pursuant to paragraph (6) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Securities Act and is used in
connection with an offering of securities subject to Rule 415, will be filed as
a part of an amendment to the registration statement and will not be used until
such amendment is effective, and that, for purposes of determining any liability
under the Securities Act, each such post-effective amendment shall be deemed to
be a new registration statement relating to the securities offered therein, and
the offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.

American International Group, Inc.

New York, New York 10270
 
Dear Sirs:
 
     In connection with the registration under the Securities Act of 1933, as
amended (the "Act"), by American International Group, Inc., a Delaware
corporation (the "Company"), of (i) 18,971,255 shares of Common Stock, par value
$2.50 per share, of the Company ("AIG Common Stock"), and, (ii) 2,300,000 shares
of $3.125 Cumulative Convertible Serial Preferred Stock, Series C, $5.00 par
value per share, of the Company (together with the AIG Common Stock, the
"Securities"), issuable in connection with the Merger (the "Merger")
contemplated by the Agreement and Plan of Merger, dated as of December 21, 1997,
as amended and restated as of January 7, 1998, and as amended by Amendment No. 1
thereto dated as of January 28, 1998 (the "Merger Agreement"), by and among
American Bankers Insurance Group, Inc., a Florida corporation ("American
Bankers"), the Company and AIGF, Inc., a Florida corporation and a newly formed
wholly-owned subsidiary of the Company, I, as Vice President and Associate
General Counsel of the Company, have examined the Merger
 Agreement and such
corporate records, certificates and other documents, and such questions of law,
as I have considered necessary or appropriate for the purposes of this opinion.
Upon the basis of such examination, I advise you that, in my opinion, assuming
that the Merger Agreement has been duly authorized, executed and delivered by
American Bankers, when the registration statement relating to the Securities
(the "Registration Statement") has become effective under the Act, the Merger
Agreement and the principal terms of the Merger have been duly approved by the
holders of the outstanding shares of the Common Stock of American Bankers and
the Preferred Stock of American Bankers, each other condition to the parties'
respective obligations to consummate the Merger has been satisfied or waived,
the Merger has become effective pursuant to Section 607.1105 of the Florida
Business Corporation Act, and the Securities have been duly issued as
contemplated by the Registration Statement and the Merger Agreement, the
Securities will be validly issued, fully paid and nonassessable.
 
     The foregoing opinion is limited to the Federal laws of the United States
and the General Corporation Law of the State of Delaware, and I am expressing no
opinion as to the effect of the laws of any other jurisdiction.
 
     I have relied as to certain matters on information obtained from public
officials, officers of the Company and other sources believed by me to be
responsible.
 
     I hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to me under the heading "Legal
Matters" in the Proxy Statement/Prospectus. In giving such consent, I do not
thereby admit that I am in the category of persons whose consent is required
under Section 7 of the Act.
 
                                          Very truly yours,
 
                                          /s/ Kathleen E. Shannon
                                          Kathleen E. Shannon

                                          January 30, 1998
 
Members of the Board of Directors
American Bankers Insurance Group, Inc.
11222 Quail Roost Drive
Miami, Florida 33157
 
Dear Board Members:
 
     You have requested that we provide to you our opinion with respect to
certain federal income tax consequences of the proposed merger of American
Bankers Insurance Group, Inc. (the "Company"), a Florida corporation, with and
into AIGF, Inc. ("Merger Sub"), a newly formed Florida corporation wholly owned
by American International Group, Inc. ("Parent"), a Delaware corporation, as
contemplated by the Agreement and Plan of Merger dated as of December 21, 1997,
as amended and restated as of January 7, 1998, and as amended by Amendment No. 1
thereto dated as of January 28, 1998, by and among Parent, Merger Sub, and
Company (the "Merger Agreement"). All capitalized terms used herein and not
otherwise defined shall have the same meaning as they have in the Merger
Agreement.
 
     In connection with the preparation of this opinion, we have examined and
relied upon (i) the Merger Agreement, (ii) the letters of representation that we
have received from Parent and Company, (iii) the Registration Statement and (iv)
such other matters as we have deemed necessary or appropriate for purposes
 of
rendering this opinion.
 
     In connection with rendering this opinion, we have assumed or obtained
representations (and are relying thereon, without any independent investigation
or review thereof) that:
 
     1. All information contained in each of the documents we have examined and
        relied upon in connection with the preparation of this opinion is
        accurate and that all copies are accurate and that all signatures
        thereof are genuine. We have also assumed that there has been (or will
        be by the Effective Time of the Merger) due execution and delivery of
        all documents where due execution and delivery are prerequisites to
        effectiveness thereof.
 
     2. The Merger will be consummated in accordance with the terms of the
        Merger Agreement without modification or exception and will not be
        restructured pursuant to the terms of Section 9.13 of the Merger
        Agreement.
 
     3. All representations made to us in letters from Parent and Company are
        true, correct, and complete in all material respects and will continue
        to be true, correct and complete at the Effective Time.
 
     Based upon and subject to the assumptions and qualifications set forth
herein, it is our opinion that for federal income tax purposes the Merger will
qualify as a reorganization under the provisions of Sections 368(a)(1)(A) and
368(a)(2)(D) of the Code and Company, Merger Sub and Parent will each be a
"party to a reorganization" within the meaning of Section 368(b) of the Code.
Our opinion is intended to address only the tax consequences to the Company
stockholders of the Merger, and is not intended to address (nor may it be relied
upon for) the tax consequences to Parent, Merger Sub or Company of the Merger.
It is also our opinion, that the discussion under the heading "Certain Federal
Income Tax Consequences of the Merger" in the Proxy Statement/Prospectus
included in the Registration Statement on Form S-4 filed with the Securities and
Exchange Commission (the "Registration Statement") is a fair and accurate
summary of the matters therein discussed.
 
     This opinion letter is based upon the Code and the relevant regulations and
interpretations and judicial precedents as of the date hereof, and if there is
any change in the applicable law or regulations, or if there is any new
administrative or judicial interpretations of the law or regulations, this
opinion letter may become inapplicable. We hereby consent to the use of this
opinion letter as an exhibit to the Registration Statement and to the use of our
name in the Registration Statement. In giving such consent, however, we do not
admit that we are in the category of persons whose consent is required by
Section 7 of the Securities Act of 1933, as

09:16 AIG to Acquire American Bankers Insurance Group for Stock Valued at $2.2
Billion

     NEW YORK AND MIAMI, Dec. 22/PRNewswire/-American International Group, Inc.
(NYSE: AIG) and American Bankers Insurance Group, Inc. (NYSE: ABI) have
announced that they have entered into a definitive agreement whereby AIG will
acquire 100 percent of the outstanding stock of American Bankers Insurance
Group. American Bankers stockholders will receive AIG stock (and in certain
circumstances at the option of AIG, cash) equal to $47.00 for each share of
American Bankers common stock, with a total value of approximately $2.2
billion. Subject to the limitations set forth in the merger agreement,
stockholders of American Bankers may elect to receive $47.00 in cash.

     The merger transaction has been approved by the Boards of Directors of
both companies, and is subject to various regulatory approvals, as well as the
approval of American Bankers stockholders. The parties expect that the
transaction will be able to close early in 1998. In connection with the
agreement, American Bankers has issued to AIG an option to purchase up to 19.9
percent of its common stock under certain conditions. In addition, certain
officers and directors
 of American Bankers holding approximately nine percent
of the outstanding common stock have agreed to vote in favor of the merger.

     The transaction, which will be treated as a purchase for accounting
purposes, provides a fixed value of $47.00 per share of American Bankers common
stock based on the average closing price of AIG's common stock during a ten day
trading period prior to closing. The exchange ratio has been initially set
based on AIG's closing stock price of $104.5625 as of December 16, 1997. If
AIG's stock price declines from the December 16 price, AIG has the option to
make up the difference by issuing additional shares or cash.

     In a statement commenting on the agreement, AIG Chairman M.R. Greenberg
said, "We are very pleased to have reached this agreement to acquire American
Bankers, a fine company with product lines that complement, but do not overlap
those of AIG. American Bankers management shares the AIG philosophy of doing
business and they have an outstanding reputation for product and service
quality, as well as a strong financial record. Culturally and from a business
standpoint, there is an excellent fit between our two organizations." American
Bankers will operate as a subsidiary of AIG with its management team remaining
in place.

     "As part of AIG, American Bankers will be able to take advantage of AIG's
relationships and global network to build its business of credit-related
insurance products marketed through financial institutions and other entities.
Particularly overseas, AIG will be able to open significant new opportunities
for American Bankers. AIG's top credit ratings should also provide an

<PAGE>   2
important benefit to American Bankers. It is anticipated that there will be
numerous synergies and expense savings leading to business efficiencies which
are expected to produce an accretion to earnings per share in 1998. All in all,
this is a win-win situation for both AIG and American Bankers. We look forward
to working with Kirk Landon, Gerry Gaston and their team in the future."

         Gerald N. Gaston, President and Chief Executive Officer of American
Bankers, commented, "We are extremely pleased to have the opportunity for
American Bankers to become a member of the AIG organization. This will create
significant new opportunities for our clients, associates and employees. With
AIG's excellent name recognition, financial strength and broad network, our
clients will benefit from being associated with one of the world's leading
providers of insurance and financial services. This is truly an outstanding
result for both organizations."

         AIG is the leading U.S.-based international insurance organization and
among the largest underwriters of commercial and industrial insurance in the
United States. Its member companies write property, casualty, marine, life and
financial services insurance in approximately 130 countries and jurisdictions,
and are engaged in a range of financial services businesses. American
International Group, Inc.'s common stock is listed on the New York Stock
Exchange, as well as the stock exchanges in London, Paris, Switzerland and
Tokyo.

         American Bankers Insurance Group Inc. (ABI) concentrates on marketing
affordable, specialty insurance products and services through financial
institutions, retailers and other entities offering consumer financing as a
regular part of their business. ABI, through its insurance subsidiaries,
operates in the United States, Canada, Latin America, the Caribbean and the
United Kingdom.

Dear Sirs:
 
     In connection with the merger (the "Merger") of American Bankers Insurance

converted into the right to receive (i) $47.00 in cash, without interest,
subject to a maximum number of shares of American Bankers Common Stock that can
be converted into cash (the "Cash Election Merger Consideration") and/or (ii) a
portion of a share of Common Stock, par value $2.50 per share ("AIG Common
Stock"), of AIG with a value of $47.00 (as determined based on the average of
the closing prices per share of AIG Common Stock as reported on the New York
Stock Exchange composite transactions reporting system for the ten trading days
ending on the third trading day prior to the date of the consummation of the
Merger), subject to AIG's right, in certain circumstances and subject to certain
limitations, to pay a portion of such consideration in cash in lieu of AIG
Common Stock (the "Stock Election Merger Consideration").
 
     The undersigned acknowledges that each Election is subject to the terms,

     The undersigned represents and warrants that the undersigned is the
exclusive owner of the shares of American Bankers Common Stock represented by
the certificate(s) identified herein.
 
     The undersigned authorizes and instructs you, as Exchange Agent, to deliver
such certificate(s) of American Bankers Common Stock to AIG and to receive on
behalf of the undersigned, in exchange for the shares of American Bankers Common
Stock represented thereby, any check for cash or any certificate for shares of

certificate(s) of American Bankers Common Stock are not delivered herewith or by
book-entry transfer, there is furnished below a guarantee of delivery of such
certificate(s) representing shares of American Bankers Common Stock from a
member of a registered national securities exchange, a member of the National
Association of Securities Dealers, Inc. or a commercial bank or trust company
having an office in the United States.
 
     Unless otherwise indicated under Special Payment Instructions below, please
issue any check and/or any certificate for shares of AIG Common Stock issuable
in exchange for the shares of American Bankers Common Stock represented by the
certificate(s) submitted herewith or submitted by book-entry transfer in the
name of the registered holder(s) of such American Bankers Common Stock.
Similarly, unless otherwise indicated under Special Delivery Instructions,
please mail any check and/or any certificate for shares of AIG Common Stock
issuable in exchange for the shares of American Bankers Common Stock represented

     Subject to the consummation of the Merger, the undersigned hereby appoints
the Exchange Agent as attorney-in-fact for the undersigned to exercise all

                                  INSTRUCTIONS
 
A.  SPECIAL CONDITIONS.
 
     1.  Time in Which to Elect.  To be effective, an election pursuant to the
terms and conditions set forth herein (an "Election") on this form or a
facsimile hereof, accompanied by the above-described certificates representing
shares of American Bankers Common Stock or by book-entry transfer of such shares
to the Exchange Agent's account at the Book-Entry Transfer Facility, must be
received by the Exchange Agent, at the address set forth above, no later than
the Election Deadline. Holders of American Bankers Common Stock whose stock
certificates are not immediately available or who cannot complete the procedure
for book-entry transfer on a timely basis may also make an effective Election by
completing Boxes I and IV of this form (or facsimile hereof), having the
Guarantee of Delivery (Box V) properly completed and duly executed, and
delivering such documents to the Exchange Agent prior to the Election Deadline
(subject to the condition that the certificates the delivery of which is thereby
guaranteed are in fact delivered to the Exchange Agent, duly endorsed in blank
or otherwise in form acceptable for transfer on the books of American Bankers,
or there is a confirmed book-entry transfer of such shares of American Bankers
Common Stock, if such procedure is available, into the Exchange Agent's account
at the Book-Entry Transfer Facility, no later than 5:00 p.m. (New York City
time) on the third New York Stock Exchange trading day after the date of
execution of such guarantee of delivery). IF A HOLDER OF SHARES OF AMERICAN
BANKERS COMMON STOCK DOES NOT MAKE AN EFFECTIVE ELECTION BY THE ELECTION
DEADLINE, SUCH HOLDER SHALL BE DEEMED TO HAVE ELECTED TO RECEIVE THE
NON-ELECTION MERGER CONSIDERATION (AS DEFINED IN THE MERGER AGREEMENT).
 
     2.  Revocation or Change of Election.  Any Election may be revoked by the
person who submitted this Election Form to the Exchange Agent and the
certificate(s) for shares withdrawn by written notice duly executed and received
by the Exchange Agent prior to the Election Deadline. Such notice must specify
the person in whose name the shares of American Bankers Common Stock to be
withdrawn had been deposited, the number of shares to be withdrawn, the name of
the registered holder thereof, and the serial numbers shown on the
certificate(s) representing the shares to be withdrawn. If an Election Form is
revoked, and the certificate(s) for shares withdrawn, the American Bankers
Common Stock certificate(s) submitted therewith will be promptly returned by the
Exchange Agent to the person who submitted such certificate(s). Upon any such
revocation, unless a duly completed Election Form is thereafter submitted, such
shares will be entitled to receive the Non-Election Merger Consideration (as
defined in the Merger Agreement). Any Election also may be effectively revoked
and amended by submission to the Exchange Agent prior to the Election Deadline
of a properly completed, duly executed and later dated Election Form.
 
     3.  Termination of Right to Elect.  If for any reason the Merger is not
consummated or is abandoned, all Election Forms will be void and of no effect
and certificate(s) for American Bankers Common Stock previously received by the
Exchange Agent and thereafter held by the Exchange Agent will be returned
promptly by the Exchange Agent to the person who submitted such stock
certificate(s).
 
B.  ELECTION AND PRORATION PROCEDURES.
 
     By properly completing this Election Form, subject to the election and
proration procedures and the other terms, conditions and limitations provided
for in the Merger Agreement and described in the Proxy Statement, each holder of
American Bankers Common Stock may elect to receive for such American Bankers
Common Stock, the Cash Election Merger Consideration or the Stock Election
Merger Consideration, or the specified combination thereof.
 
     A description of the election and proration procedures and the other terms,
conditions and limitations is set forth in the Proxy Statement under "The Merger
Agreement -- General; the Election; Merger Consideration". A full statement of
the election and proration procedures and the other terms, conditions and
limitations is contained in the Merger Agreement and all Elections are subject
to compliance with such procedures.
 
     NOTE: THE TAX CONSEQUENCES TO A HOLDER OF AMERICAN BANKERS COMMON STOCK MAY
VARY DEPENDING UPON, AMONG OTHER THINGS, WHICH OF THE ELECTION ALTERNATIVES IS
CHOSEN. IN CONNECTION WITH MAKING ANY ELECTION, A HOLDER OF AMERICAN BANKERS
COMMON STOCK SHOULD READ CAREFULLY, AMONG OTHER MATTERS, THE DESCRIPTION AND
STATEMENT SET FORTH IN THE PROXY STATEMENT UNDER "THE MERGER
AGREEMENT -- GENERAL; THE ELECTION; MERGER CONSIDERATION" AND THE INFORMATION
CONTAINED IN THE PROXY STATEMENT UNDER "THE MERGER -- CERTAIN FEDERAL INCOME TAX
CONSEQUENCES OF THE MERGER." IN ADDITION, EACH HOLDER OF AMERICAN BANKERS COMMON
STOCK IS URGED TO CONSULT WITH HIS OR HER TAX ADVISOR.

     AS A RESULT OF THE ELECTION AND PRORATION PROCEDURES AND THE OTHER TERMS,
CONDITIONS AND LIMITATIONS PROVIDED FOR IN THE MERGER AGREEMENT AND DESCRIBED IN
THE PROXY STATEMENT, HOLDERS OF AMERICAN BANKERS COMMON STOCK MAY RECEIVE AIG
COMMON STOCK OR CASH IN AMOUNTS WHICH VARY FROM THE AMOUNTS SUCH HOLDERS ELECT
TO RECEIVE. SUCH HOLDERS WILL NOT BE ABLE TO CHANGE THE AMOUNTS OF AIG COMMON
STOCK OR CASH ALLOCATED TO THEM PURSUANT TO SUCH PROCEDURES, TERMS, CONDITIONS
AND LIMITATIONS.
 
C.  RECEIPT OF CHECKS OR AIG COMMON STOCK.
 
     As soon as practicable after the Effective Time of the Merger and after the
Election Deadline, the Exchange Agent will mail cash payments by check and/or
certificate(s) for shares of AIG Common Stock to the holders of American Bankers
Common Stock with respect to each share of American Bankers Common Stock which
is included in any effective Election.
 
     No fractional shares of AIG Common Stock will be issued in connection with
the Merger. Each holder of shares of American Bankers Common Stock who would
otherwise have been entitled to receive a fraction of a share of AIG Common
Stock shall receive, in lieu thereof, cash (without interest) in an amount equal
to the product of such fractional part of a share of AIG Common Stock multiplied
by the Base Period Stock Price (as defined in the Merger Agreement).
 
D.  GENERAL.
 
     1.  Execution and Delivery.  This Election Form or a facsimile hereof must
be properly filled in, dated and signed in Box IV, and must be delivered
(together with the stock certificate(s) representing the shares of American
Bankers Common Stock as to which the election is made, book-entry transfer of
such shares to the Exchange Agent's account at the Book-Entry Transfer Facility
or a duly signed guarantee of delivery of such certificate(s)) to the Exchange
Agent at either of the addresses set forth above. A stockholder may wish to make
a copy of the completed Election Form for his records.
 
     THE METHOD OF DELIVERY OF ALL DOCUMENTS IS AT THE OPTION AND RISK OF THE
STOCKHOLDER, BUT IF SENT BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED,
PROPERLY INSURED, IS SUGGESTED.
 
     Signatures on this Election Form must be guaranteed by an eligible
guarantor institution pursuant to Rule 17Ad-15 promulgated under the Securities
Exchange Act of 1934 (an "Eligible Institution") unless (i) the Election Form is
signed by the registered holder(s) of the American Bankers Common Stock tendered
herewith and such holder(s) has (have) not completed Box II or (ii) the American
Bankers Common Stock described above are delivered for the account of an
Eligible Institution. IN ALL OTHER CASES ALL SIGNATURES MUST BE GUARANTEED BY AN
ELIGIBLE INSTITUTION. Public notaries cannot execute acceptable guarantees of
signatures.
 
     2.  Inadequate Space.  If there is insufficient space on this Election Form
to list all your stock certificates being submitted to the Exchange Agent,
please attach a separate list.
 
     3.  Signatures.  The signature (or signatures, in the case of
certificate(s) owned by two or more joint holders) on this Election Form should
correspond exactly with the name(s) as written on the face of the certificate(s)
submitted unless the shares of American Bankers Common Stock described on this
Election Form have been assigned by the registered holder(s), in which event
this Election Form should be signed in exactly the same form as the name of the
last transferee indicated on the transfers attached to or endorsed on the
certificate(s).
 
     If this Election Form is signed by a person or persons other than the
registered owners of the certificate(s) listed, the certificate(s) must be
endorsed or accompanied by appropriate stock powers, in either case signed
exactly as the name(s) of the registered owner(s) appears on the certificate(s).
 
     If this Election Form or any stock certificate(s) or stock power(s) are
signed by a trustee, executor, administrator, guardian, officer of a
corporation, attorney-in-fact or any other person acting in a representative or
fiduciary capacity, the person signing must give such person's full title in
such capacity and appropriate evidence of authority to act in such capacity must
be forwarded with this Election Form.
 
                                        7

<PAGE>   8
 
     4.  Checks and New Certificates in Same Name.  If any stock certificate(s)
representing shares of AIG Common Stock or any checks in respect of an Election
are to be registered in, or payable to the order of, exactly the same name(s)
that appears on the certificate(s) representing shares of American Bankers
Common Stock submitted with this Election Form, or a proper guarantee of
delivery thereof, no endorsement of certificate(s) or separate stock power(s) is
required.
 
     5.  Checks and New Certificates in Different Name.  If any stock
certificate(s) representing shares of AIG Common Stock or any checks in respect
of an Election are to be registered in, or payable to the order of, other than
exactly the same name(s) that appears on the certificate(s) representing shares
of American Bankers Common Stock submitted for exchange herewith, such exchange
shall not be made by the Exchange Agent unless the certificates submitted are
endorsed, Box II is completed, and the signature is guaranteed in Box IV by a
member of a registered national securities exchange, a member of the National
Association of Securities Dealers, Inc. or a commercial bank or trust company in
the United States.
 
     6.  Special Delivery Instructions.  If the checks are to be payable to the
order of, or the certificate(s) for the shares of AIG Common Stock are to be
registered in the name of, the registered holder(s) of shares of American
Bankers Common Stock but are to be mailed to someone other than the registered
holder(s) or to an address other than the address of the registered holder(s),
it will be necessary to indicate such person or address in Box III.
 
     7.  Miscellaneous.  A single check and/or single stock certificate
representing shares of AIG Common Stock will be issued.
 
     All questions with respect to this Election Form and the Elections
(including, without limitation, questions relating to the timeliness or
effectiveness of revocation of any Election and computations as to proration or
allocation of cash and AIG Common Stock) will be determined by AIG or, at AIG's
discretion, the Exchange Agent, which determinations shall be conclusive and
binding (except, with respect to computations, in the case of manifest error).
 
     8.  Backup Federal Income Tax Withholding and Substitute Form W-9.  Under
the "backup withholding" provisions of federal income tax law, the Exchange
Agent may be required to withhold 31% of the amount of any payments made to
holders of American Bankers Common Stock pursuant to the Merger. To prevent
backup withholding, each holder should complete and sign the Substitute Form W-9
included in this Form of Election and either: (a) provide the correct taxpayer
identification number ("TIN") and certify, under penalties of perjury, that the
TIN provided is correct (or that such holder is awaiting a TIN), and that (i)
the holder has not been notified by the Internal Revenue Service ("IRS") that
the holder is subject to backup withholding as a result of failure to report all
interest or dividends, or (ii) the IRS has notified the holder that the holder
is no longer subject to backup withholding; or (b) provide an adequate basis for
exemption. If the box in Part 2 of the substitute Form W-9 is checked, the
Exchange Agent shall retain 31% of reportable cash payments made to a holder
during the 60-day period following the date of the Substitute Form W-9. If the
holder furnishes the Exchange Agent with his or her TIN within 60 days of the
date of the Substitute W-9, the Exchange Agent shall remit such amounts retained
during the 60-day period to the holder and no further amounts shall be retained
or withheld from payments made to the holder thereafter. If, however, the holder
has not provided the Exchange Agent with his or her TIN within such 60-day
period, the Exchange Agent shall remit such previously retained amounts to the
IRS as backup withholding and shall withhold 31% of all reportable payments to
the holder thereafter until the holder furnishes a TIN to the Exchange Agent. In
general, if a holder is an individual, the TIN is the Social Security number of
such individual. If the certificate for American Bankers Common Stock is
registered in more than one name or is not in the name of the actual owner,
consult the Guidelines for Certification of Taxpayer Identification Number on
Substitute Form W-9 for additional guidance on which number to report. If the
Exchange Agent is not provided with the correct TIN or an adequate basis for
exemption, the holder may be subject to a $50 penalty imposed by the IRS and
backup withholding at a rate of 31%. Certain holders (including, among others,
all corporations and certain foreign individuals) are not subject to these
backup withholding and reporting requirements. In order to satisfy the Exchange
Agent that a foreign individual qualifies as an exempt recipient, such holder
must submit a statement (generally, IRS Form W-8), signed under penalties of
perjury, attesting to that individual's exempt status. A form for such
statements can be obtained from the Exchange Agent.
 
     For further information concerning backup withholding and instructions for
completing the Substitute Form W-9 (including how persons who do not have a TIN
may obtain one and how to complete the Substitute Form W-9 if American Bankers
Common Stock is held in more than one name), consult the Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9 attached
to this Election Form.

<PAGE>   9
 
     Failure to complete the Substitute Form W-9 will not, by itself, cause
American Bankers Common Stock to be deemed invalidly tendered, but may require
the Exchange Agent to withhold 31% of the amount of any payments made pursuant
to the Merger. Amounts withheld under the backup withholding rules may be
credited against a holder's tax liability, and a holder may obtain a refund of
any excess amounts withheld by filing the appropriate claim for refund with the
IRS.
 
     Additional copies of this Election Form may be obtained from the
Information Agent, MacKenzie Partners, Inc., at 800 322-2885.
 
     Any questions or requests for assistance should be directed to the
Information Agent, MacKenzie Partners, Inc., at 800 322-2885.

 Certification -- Under penalties of perjury, I certify that:

     IRS has notified me that I am no longer subject to backup withholding.
 CERTIFICATION INSTRUCTIONS -- You must cross out item (2) above if you have been notified by the IRS

me thereafter will be withheld and remitted to the IRS until I provide a

     Guarantee of Delivery to be used only if Common Stock certificates are not
     surrendered with the Election Form, and on page 12, "Guidelines for

          2. A printed form of letter which may be sent to your clients for
     whose account you hold Common Stock registered in your name or in the name

     Please furnish copies of the enclosed materials to those of your clients
for whose accounts you hold Common Stock in your name or in the name of your

     A copy of the Proxy Statement/Prospectus providing complete details and

separate cover.
 
     YOUR PROMPT ACTION IS REQUESTED. WE URGE YOU TO CONTACT YOUR CLIENTS AS
PROMPTLY AS POSSIBLE. PLEASE NOTE THAT ELECTION FORMS MUST BE RECEIVED BY THE
EXCHANGE AGENT NO LATER THAN THE ELECTION DEADLINE.
 
Please note the following:
 
          1. To be effective, an Election pursuant to the terms and conditions
     set forth on the Election Form or a facsimile thereof, accompanied by the
     certificates representing the shares of Common Stock to which the Election
     Form relates or by book-entry transfer of such shares to the Exchange
     Agent's account at a book-entry transfer facility must be received by the
     Exchange Agent, at the address set forth above, no later than the Election
     Deadline. Holders of Common Stock whose stock certificates are not
     immediately available or who cannot complete the procedure for book entry
     transfer on a timely basis may also make an effective Election by
     completing Boxes I and IV of the Election Form (or facsimile thereof),
     having the Guarantee of Delivery (Box V) properly completed and duly
     executed, and delivering such documents to the Exchange Agent prior to the
     Election Deadline (subject to the condition that the certificates the
     delivery of which is thereby guaranteed are in fact delivered to the
     Exchange Agent, duly endorsed in blank or otherwise in form acceptable for
     transfer on the books of American Bankers, or there is a confirmed
     book-entry transfer of such shares of Common Stock, if such procedure is
     available, into the Exchange Agent's account at the book-entry transfer
     facility, no later than 5:00 P.M. (New York City time) on the third New
     York Stock Exchange trading day after the date of execution of such
     guarantee of delivery). If a holder of shares of Common Stock does not make
     an effective Election by the Election Deadline, such holder shall be deemed
     to have elected to receive the Non-Election Merger Consideration (as
     defined in the Merger Agreement).
 
          2. Any Election may be revoked by the person who submitted the
     Election Form to the Exchange Agent and the certificate(s) for shares
     withdrawn by written notice duly executed and received by the Exchange
     Agent prior to the Election Deadline. Such notice must specify the person
     in whose name the shares of Common Stock to be withdrawn had been
     deposited, the number of shares to be withdrawn, the name of the registered
     holder thereof, and the serial numbers shown on the certificate(s)
     representing the shares to be withdrawn. If an Election Form is revoked,
     and the certificate(s) for shares withdrawn, the Common Stock
     Certificate(s) submitted therewith will be promptly returned by the
     Exchange Agent to the person who submitted such certificate(s). Upon any
     such revocation, unless a duly completed Election Form is thereafter
     submitted, such shares will be entitled to receive the Non-Election Merger
     Consideration (as defined in the Merger Agreement). Any Election also may
     be effectively revoked and amended by submission to the Exchange Agent
     prior to the Election Deadline of a properly completed, duly executed and
     later dated Election Form.
 
          3. If for any reason the Merger is not consummated or is abandoned,
     all Election Forms will be void and of no effect and certificate(s) for
     Common Stock previously received by the Exchange Agent and thereafter held
     by the Exchange Agent will be returned promptly by the Exchange Agent to
     the person who submitted such stock certificate(s).

              [AMERICAN BANKERS INSURANCE GROUP, INC. LETTERHEAD]
 
Dear Leveraged Employee Stock Ownership Plan Participant:
 
     As described in the accompanying Proxy Statement/Prospectus, American
Bankers Insurance Group, Inc. (the "Company") has entered into a merger
agreement with American International Group, Inc. ("AIG"), pursuant to which the
Company's common stock will be converted, at the election of the holder, but
subject to certain limitations, into $47.00 in cash, AIG common stock with a
value equal to $47.00, or a combination of cash and AIG common stock with a
value equal to $47.00.
 
     As a participant in the Company's Leveraged Employee Stock Ownership Plan
(the "LESOP"), your account in the LESOP is invested in shares of the Company's
common stock. You are entitled to vote these shares at the Special Meeting of
Common Stockholders on March 6, 1998 or any adjournment or postponement thereof
on the approval and adoption of the transactions contemplated by the merger
agreement. You are urged to read carefully the accompanying Proxy
Statement/Prospectus which describes the merger in detail.
 
     Please note that the federal income tax consequences of the merger to
holders of common stock of the Company, as described
 more fully beginning on
page 32 of the accompanying Proxy Statement/Prospectus, will not apply to the
shares allocated to LESOP participants because the LESOP is a tax-qualified
retirement plan.
 
     Not included in this package are the forms of proxy card that you will need
to vote the shares you are allocated under the LESOP at the Special Meeting of
Common Stockholders and the election form for making the cash/stock election. We
are currently calculating the number of shares allocated to each LESOP
participant. As soon as these calculations are completed to determine the number
of LESOP shares for which you are entitled to vote, we will forward to you the
materials that you will need to vote your shares under the LESOP at the Special
Meeting and an election form for your use in making the cash/stock election. The
appropriate materials will be mailed to you shortly.
 
                                          Sincerely,
 
                                          [/s/ Arthur W. Heggen]
