            This Amendment No. 2 (this "Amendment") to the Statement on

Schedule 13D/A filed by American International Group, Inc. ("AIG") on April

9, 1996 amends such Statement by amending and supplementing Items 1, 2, 3,

4, 6 and 7 as described below.  All capitalized terms used and not

otherwise defined herein shall have the meanings assigned to them in the

Statement.

Item 1.     Security and Issuer.

            This statement relates to the common shares, par value $.01 per
share ("Common Shares"), of IPC Holdings, Ltd., a Bermuda corporation
("Company").  The principal executive offices of the Company are located at
American International Building, 29 Richmond Road, Pembroke HM08, Bermuda.

Item 2.  Identity and Background.

            A list of the current executive directors and officers
("Covered Persons") of AIG, Starr International Company, Inc., The Starr
Foundation and C.V. Starr & Co. Inc., their business addresses and their
principal occupations as of the date of this Amendment are attached hereto
as Exhibit B.  Each of the Covered Persons is a citizen of the United
States, except for Messrs. Manton and Edmund Tse who are British subjects,
Mr. Cohen who is a Canadian subject and Mr. Joseph Johnson who is a
Bermudian subject.

Item 3.  Source and Amount of Funds
         or Other Consideration.

            The response to Item 4 of this Amendment is incorporated by
reference herein in its entirety.  In the event the transaction described
in Item 4 occurs, AIG anticipates that it would use its available working
capital to make the purchases requiring cash described therein.  

Item 4.  Purpose of Transaction.

            On June 3, 1996, the board of directors of the Company
authorized the Company to make a proposal to Tempest Reinsurance Company
Limited ("Tempest") that the Company acquire Tempest for cash and stock as
indicated below (the 


 4

"Combination Proposal").  AIG supports the Combination Proposal and has
been consulted in connection with the proposal's development.

            Tempest is a Bermuda corporation and is a private company
(i.e., a non-SEC reporting company).  On March 14, 1996, Tempest entered
into a definitive amalgamation agreement to combine with ACE Limited
("ACE"), a company headquartered in Bermuda.  AIG owns 264,094 common
shares of Tempest, or approximately 5% of Tempest's outstanding common
shares.  As a Tempest shareholder, AIG has opposed and is opposing the
combination of Tempest with ACE in the belief that such combination
provides inadequate value to Tempest shareholders and is strategically
unsound.  The ACE/Tempest transaction is currently scheduled to be
considered by the shareholders of ACE and Tempest at shareholders' meetings
on June 19, 1996.

            There can be no assurance that a combination between the
Company and Tempest will occur or the terms thereof, as such depend, among
other things, on approval of the Tempest board of directors and
shareholders.

            If a combination between the Company and Tempest were to occur
in the manner provided in the Combination Proposal, AIG understands from
the Company that:

            (i)   the combination would be implemented by establishing a
                  new holding company ("New IPC") for the Company and
                  Tempest;

           (ii)   shareholders of the Company (including AIG) would receive
                  common shares in New IPC in exchange for their existing
                  common shares in the Company (on a one-for-one basis) and
                  AIG's Option would be rolled-over into an option to
                  purchase New IPC common shares; and 

          (iii)   Tempest shareholders would be able to elect to exchange
                  their Tempest shares for either New IPC common shares or
                  cash, subject to certain proration if the holders of less
                  than 52% or more than 61% of the outstanding Tempest
                  common shares elect to take New IPC common shares.

            If the Combination Proposal were to occur, as a Company
shareholder AIG would receive New IPC common shares and an option to
purchase common shares in New IPC in exchange for its Company shares and
Option.  As a Tempest shareholder, AIG intends to elect to receive New IPC
common 


 5

shares with respect to all of its Tempest common shares.  AIG has also
entered into a written commitment letter ("Commitment Letter") with the
Company to purchase from New IPC a number of common shares of New IPC ("New
IPC Shares") having an aggregate purchase price of up to $65 million (or
such lesser number of New IPC Shares as will cause AIG's ownership in New
IPC to equal but not exceed 24.4% by application of the constructive
ownership rules of Section 958(a) and 958(b) of the U.S. Internal Revenue
Code) at a purchase price per New IPC Share equal to (x) the cash price
paid per Tempest common share purchased for cash in the combination,
divided by (y) the exchange ratio used to determine the number of New IPC
Shares issued in exchange for each Tempest common share so exchanged in the
transaction (for purposes of both (x) and (y), assuming no proration of the
cash or stock consideration, respectively, in the transaction).  This
commitment shall be exercisable if and to the extent that the holders of
more than 39% of the Tempest common shares elect to receive cash, as set
forth in the Combination Proposal.  The commitment is subject to the
transaction proceeding on terms substantially similar to the terms set
forth in the Combination Proposal and to the closing of the transaction
following satisfaction or waiver of the conditions thereto.  A copy of the
Commitment Letter (including the Combination Proposal as referenced
therein) is attached hereto as Exhibit F and incorporated by reference
herein in its entirety.  To the extent additional purchases pursuant to the
Commitment Letter are not required to be made in full, AIG currently
intends, following consummation of the combination, to increase its direct
ownership in New IPC to 24.4% (after giving effect to any shares
constructively owned for purposes of the U.S. Internal Revenue Code as
aforesaid) through open market or privately negotiated transactions from
time to time, subject to market conditions and other factors.  Accordingly,
while the combination of the Company and Tempest would otherwise reduce
AIG's proportionate direct common share and option interests in New IPC
relative to its current interests in IPC, through operation of the
Commitment Letter or such additional purchases, AIG currently intends to
have a 24.4% direct interest (after giving effect to any shares
constructively owned for purposes of the U.S. Internal Revenue Code as
aforesaid) in New IPC following such combination.

Item 6.  Contracts, Arrangements, Understandings
         or Relationships with Respect to
         Securities of the Issuer.

            The response to Item 4 is incorporated by reference herein in
its entirety.

Item 7.  Materials to be Filed as Exhibits.

            (B)  List of the Directors and Executive Officers of American
International Group, Inc., Starr International Company, Inc., The Starr
Foundation and C.V. Starr & Co., Inc., their business addresses and
principal occupations.

            (F)   Commitment Letter, dated June 3, 1996, from AIG to IPC
Holdings, Ltd. (including the Combination Proposal as referenced therein).

      Re:  Acquisition of Tempest Reinsurance Company, Ltd.

Ladies and Gentlemen:

In connection with the proposed combination (the "Transaction") of IPC
Holdings, Ltd., a limited liability company organized and incorporated
under the laws of Bermuda ("IPC Holdings"), and Tempest Reinsurance
Company, Ltd., a limited liability company organized and incorporated under
the laws of Bermuda ("Tempest"), pursuant to the terms set forth in the
letter (the "Proposal Letter") from IPC Holdings to Tempest dated the date
hereof, American International Group, Inc., a Delaware corporation ("AIG"),
hereby commits to IPC Holdings (the "Commitment," and by this letter, the
"Commitment Letter") to purchase from New IPC (as defined in the Proposal
Letter) a number of common shares of New IPC ("New IPC Shares") having an
aggregate purchase price of up to $65 million (or such lesser number of New
IPC Shares as will cause AIG's ownership in New IPC to equal but not exceed
24.4% by application of the constructive ownership rules of Sections 958(a)
and 958(b) of the U.S. Internal Revenue Code) at a purchase price per New
IPC Share equal to (x) the cash price paid per common share, $10 par value
per share, of Tempest ("Tempest Shares") purchased for cash in the
Transaction, divided by (y) the exchange ratio used to determine the number
of New IPC Shares issued in exchange for each Tempest Share so exchanged in
the Transaction (for purposes of both (x) and (y), assuming no proration of
the cash or stock consideration, respectively, in the Transaction).  This
Commitment shall be exercisable if and to the extent that the holders of
more than 39% of the Tempest Shares elect to receive cash in the
amalgamation contemplated by the Transaction, as set forth in the Proposal
Letter.  The Commitment is subject to the Transaction proceeding on terms
substantially similar to the terms set forth in the Proposal Letter and to
the closing of the Transaction following satisfaction or waiver of the
conditions thereto.

AIG hereby represents and warrants to IPC Holdings that AIG has all
requisite corporate power and authority to enter into this Commitment
Letter and to consummate the transactions

contemplated hereby.  The execution and delivery of this Commitment Letter
by AIG, the performance by AIG of its obligations hereunder and the
consummation by AIG of the transactions contemplated hereby have been duly
authorized by all necessary corporate action on the part of AIG.  This
Commitment Letter has been duly executed and delivered by AIG and
constitutes a legal, valid and binding obligation of AIG, enforceable by
IPC Holdings against AIG in accordance with its terms, subject with respect
to enforceability to the effect of bankruptcy, fraudulent conveyance,
insolvency, reorganization, moratorium, or similar laws now or hereafter
affecting the enforcement of creditors' right generally and to the
availability of equitable remedies.

This Commitment Letter shall be governed by and construed in accordance
with the laws of the State of New York without regard to conflicts of laws
rules thereof.  IPC Holdings is the only party entitled to enforce this
Commitment Letter and there are no third party beneficiaries.



                                    Very truly yours,

                                                      June 3, 1996


Mr. Donald Kramer
Co-Chairman
Tempest Reinsurance Company, Ltd.
14 Par-La-Ville Road
Hamilton, HM 08 Bermuda

Dear Mr. Kramer:

      On behalf of the Board of Directors of IPC Holdings, Ltd., I am
writing to submit the following proposal to combine our companies.  We have
always held Tempest in high regard and believe strongly that the
combination of our companies will create a leading property catastrophe
reinsurer in Bermuda.  Because of the very significant benefits that this
combination will provide to your Company and your shareholders, we ask that
you and your Board of Directors give prompt and careful consideration to
our proposal.

Strategic Benefits of IPC/Tempest Amalgamation

      The amalgamation of our two companies would create opportunities for
long-term growth and provide the combined company with significant
strategic advantages:

      o   The amalgamation would, in a single step, expand our client
          relationships to a level that would otherwise require several
          years for either company to achieve on its own.

      o   The combined company would be the third largest property
          catastrophe company in Bermuda in terms of market value and
          equity.

      o   The amalgamation would create a company with a broader
          geographic spread of risk and an expected improved profitability.

      o   The combined company would have a lower expense ratio since it
          would realize significant cost savings through consolidation of 


 2



          administrative activities and the continuation of AIG's existing
          relationship with IPC, which provides a lower cost structure than 
          Tempest has under its current agreement with General Re.

      o   The combined company would be focused on the property
          catastrophe reinsurance business, which we believe has greater
          prospects for high returns than joining with a much larger, lower
          return, multiline insurer  in a transaction having minimal
          synergies.

      o   We expect this deal to be accretive on the basis of book value
          per share and first full year of earnings per share -- offering
          shareholders significant upside potential for stock appreciation.

Terms

      We propose that IPC and Tempest combine to form a new holding company
("New IPC").  In the transaction, Tempest shareholders would receive
aggregate cash and stock consideration of $943 million, representing $180
per share.  This amount would be subject to adjustment for changes in
Tempest's book value from March 31, 1996 through the closing date.   The 
consideration would be payable as follows:

      $146 million  -   Payments from Tempest to General Re to (i)
                        repurchase 75% of the Tempest shares held by
                        General Re, (ii) cancel General Re's options to
                        purchase Tempest shares and (iii) terminate all
                        contractual arrangements between General Re and
                        Tempest.

      $100 million  -   Cash dividend by Tempest on its remaining
                        shares ($22.60 per share), as adjusted for changes
                        (positive or negative) in Tempest's book value from
                        March 31, 1996 to the closing date (excluding the
                        above payments to General Re).

      $697 million  -   Cash and New IPC common stock issued in an
                        amalgamation.  Tempest shareholders would receive
                        $157.40 per share, which they could elect to get
                        paid either in cash or New IPC common stock,
                        subject to certain limits.

      ______________

      $943 million  -   Total Consideration

      In the opinion of Wachtell, Lipton, Rosen & Katz, IPC's U.S. counsel,
the receipt of New IPC common stock in exchange for Tempest shares should
be tax-free 



 3



to Tempest shareholders under the U.S. federal income tax laws.  We note
that no tax opinion is provided in the ACE proxy statement.

      Our proposal contemplates a collar to protect the value of the New
IPC stock to be received  by  Tempest shareholders as long as the average
price of the IPC stock during the ten-day measurement period prior to the
shareholder meetings is not less than $18 and not more than $22.   Tempest
would have the right to terminate the agreement if the average IPC stock
price was less than $16 during the measurement period unless IPC elected to
top up the number of New IPC shares issued to Tempest shareholders.   If
IPC's stock price during the measurement period were to exceed  $24, the
number of New IPC shares to be issued would be adjusted in order to put a
cap on the maximum value of the consideration issued in the amalgamation of
approximately $735 million (excluding the dividend).  IPC would not have
the right to "walk away" if the IPC stock price was above or below
specified prices during the measurement period.

      Under the cash/stock election for the amalgamation, Tempest
shareholders would be able to elect to exchange their Tempest shares for
either cash or stock, subject to certain proration only if the holders of
less than 39% or more than 48% of the outstanding Tempest shares elect to
take cash.  The cash consideration in the amalgamation will constitute a
minimum of $275 million and a maximum of $340 million, with the additional
cash funded by AIG's equity commitment described below.

      IPC shareholders would exchange their IPC shares in the transaction
for New IPC shares on a one-for-one, tax-free basis.

Comparison with ACE Amalgamation

      Under the ACE transaction, Tempest shareholders (other than General
Re) would receive a $9.66 cash dividend per share (based upon the March 31,
1996 balance sheet) and, assuming ACE's stock stays above $45, 3.2091 ACE
ordinary shares for each Tempest share.  Such number of ACE shares were
valued at $154.04 based upon today's $48 closing price of ACE stock.   In
addition, Tempest shareholders would be entitled to an additional
contingent dividend based upon the increase in book value from March 31,
1996, but only after making a provision for losses at the greater of actual
incurred losses or 42% of year to date earned premiums.

      The following chart summarizes the consideration payable per share to
Tempest shareholders (other than General Re) under our proposal and under
the ACE transaction, in each case based upon market prices of IPC and ACE
stock on June 3, 1996:

                          IPC                            ACE
                          ---                            ---

       Dividend through   $22.60                         $9.66
       3/31/96


       Exchange           $157.40 in New IPC             $154.04 in
                          shares or cash                 ACE shares

       Total              $180.00                        $163.70


       Contingent         Subject only to                Subject to greater
       Dividend           actual losses                  of actual losses or
                                                         42% loss ratio

      To fully appreciate our proposal, I would like to highlight some
important comparisons between our proposal and the transaction contemplated
by ACE:

      o Our overall proposal offers at least a $90 million, or 11%,
        premium to the ACE transaction, as well as the prospect of
        significantly higher contingent dividends because our proposal
        does not assume a minimum 42% loss ratio.  For example, if the
        actual loss ratio for the three months ended June 30, 1996 is 20%,
        we estimate that our proposal would result in an additional $10
        million advantage compared to the ACE transaction.

      o Almost 50% of the aggregate consideration paid to Tempest
        shareholders (other than General Re) in our proposal is cash,
        compared to only 6% in the ACE transaction.

      o Our proposal provides Tempest shareholders protection from
        declines in the IPC share price up to 10%.  In contrast,  at the
        recent stock price levels, the value of the ACE proposal is at
        risk for any downward movement in ACE's stock price.  Each $1
        decline in the ACE stock price (down to a price of $45) will
        reduce the value of their offer by $13 million, and
        correspondingly increase the price advantage of our proposal.  

      o Our proposal offers the potential for greater consideration if
        the IPC stock price appreciates above $22. In contrast, ACE (or
        Tempest) has the 



 5



        right to terminate the ACE transaction if the average ACE stock price
        during its measurement period is over $49.  On May 31, 1996 -- the first
        day of ACE's measurement period -- the closing price of ACE stock
        was $49.

      o Our proposal provides General Re, your sponsor and principal
        shareholder, with aggregate consideration having the same value on
        a per share basis as paid to other Tempest shareholders, as well
        as the opportunity to participate in the upside potential in the
        transaction through equity participation in New IPC and the
        contingent dividend.  In return for such payment, General Re would
        be required to cancel its options and all of its contracts with
        Tempest.  The following table compares the payments to General Re:

                          Payment to General Re (in millions)
                                      IPC        ACE

Cash payment for shares,
cancellation of options, and         $146       $172
termination of contracts

Dividend                                6         --

Stock (assuming 100%                   43         -- 
equity election)
                                     ----       ----

Total                                $195       $172


      o Our proposal allows shareholders to continue to realize the
        exceptional returns available in the property catastrophe
        reinsurance industry through a liquid investment in a top quality
        company,  while allowing investors to realize a cash return on a
        portion of their holdings.  Moreover, as we discussed earlier, we
        expect this transaction to be accretive on the basis of both book
        value per share and our first full year of earnings per share --
        offering shareholders significant upside potential for stock
        appreciation.

      o In contrast, the ACE proposal forces your shareholders either
        (i) to maintain an investment in a lower return company whose
        diversification could be achieved instead through an investment in
        ACE and an investment in existing Bermuda property catastrophe
        reinsurers or (ii) to receive cash through the sale of the ACE
        shares (in which case, they incur market risk as well as
        transaction costs).

AIG Support and Equity Commitment

      American International Group, Inc. ("AIG") is the largest shareholder
of IPC and provides administrative and investment management services to
IPC pursuant to contractual arrangements.  As you know, AIG is also a
shareholder of Tempest and has expressed to Tempest shareholders its "deep
reservations" about the proposed ACE transaction.  AIG believes the ACE
transaction provides inadequate value to Tempest shareholders and is not a
prudent diversification of Tempest.  We have consulted with AIG regarding
our proposal and have been informed that AIG strongly endorses it.  AIG has
also advised us that if our proposal were to be consummated, AIG would
elect in the amalgamation to receive New IPC shares with respect to its
entire investment in Tempest.  

      Furthermore, AIG has committed to purchase up to $65 million of New
IPC common stock from New IPC to the extent that holders of more than 39%
of  Tempest's shares elected to receive cash in the amalgamation thereby
increasing AIG's equity interest in the combined company up to
approximately 24.4% of the outstanding shares -- AIG's current percentage
ownership of IPC.  AIG's equity commitment will permit IPC to increase the
relative cash/stock mix of its proposal and reduce the risk and amount of
proration in the event the cash election were oversubscribed.  To the
extent the equity commitment is not fully drawn by New IPC, AIG has
indicated its intention following the consummation of the transaction to
acquire additional shares of New IPC in open market or privately negotiated
transactions from time to time, subject to market conditions and other
factors, in order to increase its equity interest to approximately 24.4%.

Financing

      We have had discussions with a major money center bank with respect
to all of the financing required to complete the transaction.  Such bank
has advised IPC it is prepared to execute a commitment letter for the
entire amount.  We expect that all borrowings will be repaid by December
31, 1996 from the combined company's cash flow and an orderly disposition
of a portion of the investment portfolio.

Process

      Our Board of Directors strongly supports the proposed transaction and
has authorized management to pursue this proposal with you.  IPC's
financial advisor, Morgan Stanley & Co. Incorporated, has advised IPC's
Board of Directors that, subject to, among other things, completion of its
due diligence review of Tempest, if IPC enters into a definitive agreement
with Tempest on the terms set forth in this proposal, Morgan Stanley
expects to provide an opinion to IPC's Board that the consideration to be
paid is fair, from a financial point of view, to IPC's shareholders.

      We have reviewed the information contained in the ACE proxy statement
and the Tempest Annual Reports regarding your business, financial
condition, results of operations and prospects.  However, our proposal is
necessarily subject to our completion of an appropriate due diligence
review, including access to non-public information regarding Tempest.  
Since we are in the same business as you, we anticipate that such due
diligence can be completed within 3-4 days with your cooperation.  Please
furnish us with a customary confidentiality agreement that we will execute
prior to receiving such non-public information.

      We have also carefully reviewed the Agreement and Plan of
Amalgamation dated as of March 14, 1996 (the "ACE Amalgamation Agreement")
relating to the ACE transaction.  Subject to our receipt and review of the
Disclosure Letter referred to in the ACE Amalgamation Agreement and your
cooperation with our due diligence review, we would be prepared to move
expeditiously to complete a definitive agreement to effect our proposal. 
Moreover, we would expect the definitive agreement to be substantially
similar to the ACE Amalgamation Agreement.  For example, we expect that the
representations, warranties and covenants in our definitive agreement will
essentially mirror those that you have negotiated with ACE, although we
would delete Section 5.09 (relating to the waiver of appraisal rights and
the lock-up) and Section 5.17 (relating to certain employee arrangements)
and would address employee benefit issues once we understand the existing
arrangements.  

      Our proposal  is subject to termination of the ACE Amalgamation
Agreement in accordance with its terms (without the payment of any
termination fee or expenses to ACE unless such payments are required under
ACE's current contract), approval of a mutually satisfactory amalgamation
agreement by our respective Boards of Directors, and approval by our
respective shareholders.  We anticipate that, with Tempest's cooperation,
our transaction would be consummated by September 30, 1996.  In order to
provide greater certainty of consummation for our proposal, we would delete
the following conditions to closing that are contained in the ACE
Amalgamation Agreement:  



















 8

        *  Section 6.02(c) (no material change in acquirer's financial
           statements)
        *  Section 6.02(d) (no material adverse effect on acquirer)
        *  Section 6.03(c) (no material change in the Company's financial
           statements)
        *  Section 6.03(d) (no material adverse effect on the Company) 
        *  Section 6.03(e) (no national crisis or material adverse change
           in financial markets)
        *  Section 6.03(f) (waiver of appraisal rights by 75% of Company's
           shareholders)
        *  Section 6.03(l)(iv) (stop loss reinsurance with General
           Re)(appropriate changes would be made to other General Re
           conditions to conform to our proposal described above)

      I would like to reiterate that the combination of our two companies
will create a leading reinsurer in the Bermuda market which should provide
a tremendous investment opportunity for our shareholders.  This will enable
your shareholders to continue their investment in a focused, specialty
property catastrophe reinsurer that was the basis of their original
investment.  On the basis of our superior proposal, we are confident that
your Board will carry out its fiduciary duties and provide the Tempest
shareholders the opportunity to realize these benefits.  In view of the
importance of this matter, time is of the essence and we look forward to
your earliest possible response.

                                                Sincerely,

                                                /s/ J.C.H. Johnson

                                                J.C.H. Johnson
