                  This statement relates to the Common Stock, $.001 par value
(the "Common Stock"), of ALCOHOL SENSORS INTERNATIONAL, LTD. (the "Company").
The principal executive offices of the Company are located at 11 Oval Drive,
Islandia, New York 11722.


Item 2.           Identity and Background.

                  (a) through (c). This statement is being filed by American
International Group, Inc., a Delaware corporation ("AIG"), on behalf of AIG and
American International Insurance Company, a New York corporation ("AIIC") and a
subsidiary of AIG. AIG is a holding company 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. AIIC engages in mass 
marketing of personal lines coverages, primarily private passenger auto
insurance.

                  Starr International Company, Inc., a private holding company
incorporated in Panama ("SICO"), The Starr Foundation, a New York not-for-profit
corporation ("The Starr Foundation"), and C.V. Starr & Co., Inc., a Delaware
corporation ("Starr"), have the right to vote approximately 16.14%, 3.46% and
2.39%, respectively, of the outstanding common stock of AIG. The principal
executive offices of SICO are located at 29 Richmond Road, Pembroke, Bermuda.
The principal executive offices of The Starr Foundation and Starr are located at
70 Pine Street, New York, New York 10270. The names of the directors and
executive officers ("Covered Persons") of AIG, AIIC, SICO, The Starr Foundation
and Starr, their business addresses and principal occupations are set forth in
Exhibit 1 attached hereto, which is incorporated herein by reference in its
entirety. The business address indicated for each Covered Person is also the

Persons is a citizen of the United States, except for Messrs. Johnson, Manton,

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

                  Pursuant to a Convertible Preferred Stock and Warrant Purchase
Agreement, dated as of December 20, 1996 (the "Stock Purchase Agreement"), the
Company issued to AIIC 833,333 shares of Series A Cumulative Non-redeemable
Convertible Preferred Stock (the "Convertible Preferred Stock") and 833,333
Common Stock purchase warrants (the "Warrants"). The Convertible Preferred Stock
yields a cumulative dividend of 9% per annum based on the stated value of the
stock. The shares of Convertible Preferred Stock are convertible at any time
into Common Stock based on a conversion price of $4.50 per share. Based on a
stated value of $3.00 per share on the closing date, the Convertible Preferred
Stock would convert into 555,555 shares of Common Stock on the closing date. The
Warrants entitle AIIC to purchase 833,333 shares of Common Stock for two years
at a purchase price of $5.50 per share.

                  AIIC used its available working capital to purchase the
Convertible Preferred Stock and the Warrants.

Item 4.           Purpose of Transaction.

                  The purpose of the acquisition of the Convertible Preferred
Stock and the Warrants, as described in Item 3 and Item 5 below, was 
investment. AIG and AIIC will continue to review their respective investments 
in the Company and, dependent upon their evaluation of market conditions, 
applicable regulatory requirements, and the Company's business prospects and 
future developments, may from time to time, determine to increase, decrease or 
dispose of their equity positions in the Company. Such transactions, if any, 
may be made through the exercise of conversion rights or warrants, purchases 
or sales in the open market or otherwise.


Item 5.           Interest in Securities of Issuer.

                  (a) and (b). The information required by these paragraphs is
set forth in Items 7 through 11 and Item 13 of each of the cover pages to this

                  Section 3.12. Taxes. "Taxes" shall mean all taxes, charges,
fees, Liens, duties or other assessments, however denominated, including any
interest or penalties that may become payable in respect thereof, imposed by the
United States government, any state, local or foreign government or any agency
or political subdivision of any such government (a "Tax Authority"), which taxes
shall include, without limiting the generality of the foregoing, all income
taxes, payroll and employee withholding taxes, unemployment insurance, social
security, sales and use taxes, excise taxes, capital taxes, franchise taxes,
gross receipt taxes, occupation taxes, real and personal property taxes, value
added taxes, stamp taxes, transfer taxes, workers' compensation taxes and other
obligations of the same or of a similar nature. All tax returns or reports
required to be filed by or on behalf of the Company or any Subsidiary have been
timely filed or requests for extensions have been timely filed and, to the best
knowledge of the Company, any such extension has been granted and has not
expired, and all such filed returns are complete and accurate. All Taxes due
from the Company or any Subsidiary for periods through the Closing Date have
been paid in full or an adequate provision has been made for any such Taxes on
the financial statements included in the Quarterly Report (in accordance with
generally accepted accounting principles). There is no audit, examination,
deficiency, or refund litigation pending or threatened, with respect to any
Taxes of the Company or any Subsidiary that could result in a determination that
would have a Material Adverse Effect on the Company. All Taxes, interest,
additions and penalties due with respect to completed and settled examinations
or concluded litigation relating to it have been paid in full or adequate
provision has been made for any such Taxes on the financial statements included
in the Quarterly Report (in accordance with generally accepted accounting
principles). The Company has not executed an extension or waiver of any statute
of limitations on the assessment or collection of any Tax that is currently in
effect. No rulings have been issued by or agreements entered into with any Tax
Authority with respect to the Company or any Subsidiary.

                  Section 3.13. ERISA and Employee Benefit Plans. Except as
listed in Schedule 3.13, neither of the Company nor any Subsidiary maintains,
sponsors, is required to make contributions to or otherwise has any liability,
direct, indirect, contingent or otherwise, with respect to any pension, profit
sharing, thrift or other retirement plan, employee stock ownership plan,
deferred compensation, stock ownership, stock purchase, performance share, bonus
or other incentive plan, severance plan, health or group insurance plan, welfare
plan, or other similar plan, agreement, policy, arrangement or understanding,
whether written or oral, whether or not such plan is intended to be qualified
under Section 401(a) of the Code, including any employee benefit plan within the
meaning of Section 3(3) of ERISA, which plan covers any employee or former
employee of the Company or any Subsidiary (collectively, the "Plans"). The
Company has delivered to the Purchaser true, correct and complete copies of (i)
any employment agreements and any procedures and policies (including summaries
of any procedures and policies that are unwritten) relating to the employment of
employees of the Company and each Subsidiary and the use of temporary employees
and independent contractors by the Company and each Subsidiary, (ii) each Plan
and all related trust agreements, insurance and other material contracts, and
summary plan descriptions and summaries of material modifications relating to
each Plan and any 



                                      -11-
   12
related material communications distributed to participants under the Plans and
(iii) the latest reports which have been filed (or are in fully completed form
for filing) with the Internal Revenue Service and the Department of Labor with
respect to each Plan. No Plan is subject to Title IV of ERISA. With respect to
each Plan, to the best knowledge of the Company, no party in interest or
disqualified person (as defined in Section 3(14) of ERISA and Section 4975 of
the Code, respectively) has at any time engaged in a transaction which could
subject the Company or any of the Subsidiaries, directly or indirectly, to a
Tax, penalty or liability for prohibited transactions imposed by ERISA or
Section 4975 of the Code. To the best knowledge of the Company, no fiduciary (as
defined in Section 3(21) of ERISA) with respect to any Plan has breached any of
the responsibilities or obligations imposed upon fiduciaries under Title I of
ERISA. Each Plan is and has been operated in compliance in all material respects
with its terms and all applicable reporting, disclosure and other requirements
of ERISA and the Code as they relate to such Plan, including where applicable
the group health plan continuation coverage requirements set forth in Part 6 of
Subtitle B of Title I of ERISA and Section 4980B of the Code, and by its terms
can be terminated at any time. As of the Closing Date, the Company and each
Subsidiary shall have made all required contributions under each Plan for all
periods through and including the Closing Date or adequate accruals therefor
will have been provided for by the Company or such Subsidiary. No Person will be
entitled to any severance benefits under the terms of any Plan solely by reason
of the transactions contemplated by this Agreement, the Registration Rights
Agreement, the Warrant Certificate or the Shareholders Agreement. There are no
actions, claims, lawsuits or arbitrations pending or, to the best knowledge of
the Company, threatened with respect to any Plan. No Plan provides for the
payment of retiree or post-termination medical, health, disability, life
insurance or other welfare benefits. Neither the Company nor any of the
Subsidiaries has or has ever had any ERISA Affiliate. For purposes of this
Agreement, "ERISA Affiliate" means any Person which would be treated as a single
employer with the Company or any Subsidiary under Section 414(b), (c), (m) or
(o) of the Code and the regulations promulgated thereunder or Title IV of ERISA.
Neither the Company nor any Subsidiary has incurred any liability to the Pension
Benefit Guaranty Corporation. Each Plan which is intended to be "qualified"
within the meaning of Section 401(a) of the Code (and the exempt trust
thereunder), has been determined by the Internal Revenue Service to satisfy the
qualification requirements of Sections 401(a) and 501(a) of the Code and every
Plan (and related trust) which is intended to comply with the terms and
requirements of applicable statutes does so comply in all material respects.
Each of the Company and each Subsidiary has never contributed to, or withdrawn
in a complete or partial withdrawal from, any multiemployer plan (within the
meaning of Subtitle E of Title IV of ERISA) or incurred contingent liability
under Section 4204 of ERISA. Neither the Company nor any Subsidiary has proposed
or agreed to any increase in benefits under any Plan (or the creation of new
benefits) or change in employee coverage which would increase the expense of
maintaining any such Plan. The consummation of the transactions contemplated by
this Agreement and the Registration Rights Agreement, the Warrant Certificate
and the Shareholders Agreement will not result in an increase in the amount of
compensation or benefits or accelerate the vesting or timing of payment of any
benefits or compensation payable in respect of any employee.

                  Section 3.14. Contracts, etc. Neither the Company nor any of
the Subsidiaries, nor to the best knowledge of the Company any other party
thereto, is in default or breach (and there is no event which, with notice or
lapse of time or both, would constitute such a default or breach) under any
agreement, arrangement, bond, commitment, contract, franchise, indemnity,
indenture, instrument, lease, license or understanding, whether or not in
writing, to which it is a party or to which any of its assets are subject, in
each case that has had or may reasonably be expected to have a Material Adverse
Effect on the Company.

                  Section 3.15. Legal Proceedings, etc. (i) There is no legal,
administrative, arbitral or other investigation, claim, action or proceeding
pending or, to the best knowledge of the Company, threatened against the Company
or any of the Subsidiaries or any of their respective directors, officers or
employees or to which any of their properties are subject or against any Plan or
the trustee of any Plan which challenges the validity of this Agreement, the
Registration Rights Agreement, the Warrant Certificate, the Shareholders
Agreement, the Certificate of Amendment, the Preferred Stock, the Warrants or
any action taken or to be taken pursuant hereto or thereto, which seeks to
impose or confirm any limitation on the ability of the Purchaser effectively to
acquire, hold or exercise full rights of ownership of the Preferred Shares, the
Warrants or the Common Shares, or, except as disclosed on Schedule 3.15 hereto,
which in the aggregate with all other such investigations, claims, actions and
proceedings would have a Material Adverse Effect on the Company; (ii) neither
the Company nor any Subsidiary is a party or is subject to the provisions of any
order, writ, injunction, award, settlement, judgment or decree of any court,
board or other governmental agency or instrumentality or administrative agency
or any arbiter, which would, individually or in the aggregate, have a Material
Adverse Effect on the Company; and (iii) there is no action, suit, proceeding or
investigation by the Company or any Subsidiary currently pending or which the
Company or any Subsidiary intends to initiate.

                  Section 3.16. Brokerage. No placement agent, banker, broker or
finder has acted directly or indirectly for the Company in connection with this
Agreement or the transactions contemplated hereby, and no placement agent,
banker, broker or finder is entitled to any commission, brokerage or finder's
fee in respect thereof based in any way on agreements, arrangements or
understandings made by or on behalf of the Company.

                  Section 3.17. Agreements; Action. (a) Except as otherwise
disclosed in Schedule 3.17 hereto, there are no agreements, understandings,
instruments, contracts, proposed transactions, judgments, orders, injunctions,
awards, settlements, writs or decrees to which the Company or any Subsidiary is
a party or by which it is bound which may involve or contain (i) obligations
(contingent or otherwise) of, or payments to, the Company or any Subsidiary in
excess of $50,000 (other than obligations of, or payments to, the Company or any
Subsidiary arising from purchase or sale agreements entered into in the ordinary
course of business), (ii) the license of any patent, copyright, trade secret or
other proprietary right to or from the Company (other than licenses arising from
the purchase of "off the shelf" or other standard products), (iii) provisions
restricting or affecting the development, manufacture or distribution of the
Company's 

                                      -13-

   14

or any Subsidiary's products or services or (iv) indemnification by
the Company or any Subsidiary with respect to infringements of proprietary
rights (other than indemnification obligations arising from purchase or sale
agreements entered into in the ordinary course of business).

                           (b) Since December 31, 1995, neither the Company nor
any Subsidiary has incurred any indebtedness for money borrowed or any other
liabilities (other than with respect to obligations incurred in the ordinary
course of business) individually in excess of $50,000 or, in the case of
indebtedness and/or liabilities individually less than $50,000, in excess of
$250,000 in the aggregate.

                           (c) For the purposes of subsections (a) and (b)
above, all indebtedness, liabilities, agreements, understandings, instruments,
contracts and proposed transactions involving the same Person (including Persons
the Company has reason to believe are affiliated therewith) shall be aggregated
for the purpose of meeting the individual minimum dollar amounts of such
subsections.

                           (d) Neither the Company nor any Subsidiary has
engaged in the past three (3) months in any discussion (i) with any Person or
any representative of such Person regarding the consolidation or merger of the
Company or any Subsidiary with or into any such Person or another Person, (ii)
with any Person regarding the sale, conveyance or disposition of all or
substantially all of the assets of the Company or any Subsidiary, or a
transaction or series of related transactions in which more than fifty percent
(50%) of the voting power of the Company or any Subsidiary is disposed of or
(iii) regarding any other form of acquisition, liquidation, dissolution or
winding up of the Company or any Subsidiary.

                  Section 3.18. Transactions with Related Persons. (a) Except as
otherwise disclosed in Schedule 3.18 hereto, there are no agreements,
understandings or proposed transactions of the Company or any Subsidiary with,
and no debts, obligations or liabilities of the Company or any Subsidiary owed
to, any of their respective officers, directors, shareholders, employees,
consultants or Affiliates or any Affiliate thereof other than (i) for payment of
salary for services rendered, (ii) reimbursement for reasonable expenses
incurred on behalf of the Company or any such Subsidiary and (iii) for other
standard employee benefits made generally available to all employees (including
stock option agreements outstanding under any stock option plan approved by the
Board of Directors of the Company or any such Subsidiary). None of the officers,
directors or shareholders of the Company or any Subsidiary, or any members of
their immediate families or any of their Affiliates, is indebted to, or has any
cause of action or legal claim against, the Company or any Subsidiary or, to the
best knowledge of the Company, has any direct or indirect ownership interest in
any Person with which the Company or any Subsidiary is affiliated or with which
the Company or any Subsidiary has a business relationship, or any Person which
competes with the Company or any Subsidiary, except that officers, directors
and/or shareholders of the Company or any Subsidiary may own stock in publicly
traded companies 





                                      -14-
   15

which may compete with the Company or any Subsidiary. No officer, director or
shareholder of the Company or any Subsidiary, or any member of their immediate
families or any of their Affiliates, is, directly or indirectly, interested in
any material contract with the Company or any Subsidiary. Except as otherwise
disclosed in Schedule 3.18, neither the Company nor any Subsidiary is a
guarantor, indemnitor or contributor of any indebtedness or liability of any
other Person.

                  Section 3.19. Title to Properties and Assets; Liens, etc. Each
of the Company and each Subsidiary has good and marketable title to its
properties and assets, and good title to its leasehold estates, in each case
subject to no Lien, other than (i) those identified on the Balance Sheet, (ii)
those resulting from taxes which have not yet become delinquent, (iii) minor
Liens which do not materially detract from the value of the property or
materially impair the operations of the Company or such Subsidiary and (iv)
those that have otherwise arisen in the ordinary course of business. All
facilities, machinery, equipment, fixtures, vehicles and other properties owned,
leased or used by the Company and each Subsidiary are in good operating
condition and repair and are reasonably fit and usable for the purposes for
which they are being used. Schedule 3.19 hereto sets forth a true, complete and
correct list of all of the real property that is leased to the Company and each
Subsidiary. The Company and each Subsidiary enjoys peaceful and undisturbed
possession of all such real property leased to it. Neither the Company nor any
Subsidiary has ever owned or presently owns any real property. The Company has
never manufactured or produced, and does not presently manufacture or produce,
any of its products or goods; except as set forth on Schedule 3.19, such
products and goods have been and are presently manufactured and produced by
independent third Persons.

                  Section 3.20. Patents and Trademarks. Each of the Company and
each Subsidiary owns or possesses sufficient legal rights to all trademarks,
service marks, trade names, copyrights, trade secrets, patents, information,
other proprietary rights and processes necessary for its business as now
conducted and as proposed to be conducted, without any known infringement of the
rights of others. There are no outstanding options, licenses or agreements of
any kind relating to the foregoing, nor is the Company or any Subsidiary bound
by or a party to any options, licenses or agreements of any kind with respect to
the trademarks, service marks, trade names, copyrights, trade secrets, patents,
licenses, information and other proprietary rights and processes of any other
Person other than such licenses or agreements arising from the purchase of "off
the shelf" or standard products. Each of the Company and each Subsidiary has not
received any communications alleging that the Company or any Subsidiary has
violated or, by conducting its business as proposed, would violate any of the
trademarks, service marks, trade names, copyrights, trade secrets, patents or
other proprietary rights of any other Person. Each of the Company and each
Subsidiary is not aware that any of its employees is obligated under any
contract (including licenses, covenants or commitments of any nature) or other
agreement, or subject to any judgment, decree, injunction, award, settlement or
order of any court or administrative agency, that would interfere with his or
her duties to the Company or any 





                                      -15-
   16

Subsidiary or that would conflict with the Company's or any Subsidiary's
business as presently conducted and as proposed to be conducted.

                  Section 3.21. Employees. Each of the Company and each
Subsidiary has no collective bargaining agreements with any of its employees.
There is no labor union organizing activity pending or, to the Company's best
knowledge, threatened with respect to the Company or any Subsidiary. To the
Company's best knowledge, no employee of the Company or any Subsidiary, nor any
consultant with whom the Company or any Subsidiary has contracted, is in
violation of any term of any employment contract, proprietary information
agreement or any other agreement relating to the right of any such individual to
be employed by, or to contract with, the Company or such Subsidiary because of
the nature of the business to be conducted by the Company or such Subsidiary;
and, to the Company's best knowledge, the continued employment by the Company
and each Subsidiary of its present employees, and the performance of the
Company's and each Subsidiary's contracts with its independent contractors, will
not result in any such violation. The Company and the Subsidiaries have not
received any notice alleging that any such violation has occurred. Except as set
forth in Schedule 3.21 hereto, no employee or consultant of the Company or of
any Subsidiary has been granted the right to continued employment by the Company
or such Subsidiary or to any material compensation following termination of
employment with or by the Company or such Subsidiary.

                  Section 3.22. Permits. Each of the Company and each Subsidiary
has all franchises, permits, licenses, consents and approvals and any similar
authority, all of which are in full force and effect, necessary for the conduct
of its business as now being conducted by it, the lack of which would have a
Material Adverse Effect on the Company.

                  Section 3.23. Environmental Matters. As used herein, "Subject
Premises" means the real property now owned, operated, used or leased or
previously owned, operated, used or leased (but only through the date of
termination of such ownership, operation, use or lease) by, to or for the
Company or the Subsidiaries or any of their Affiliates. (i) To the best
knowledge of the Company, none of the Subject Premises has any condition or
conditions which would require notification or remediation under any
Environmental Law (collectively, "Environmental Defects"); (ii) except as set
forth on Schedule 3.23 hereto, to the best knowledge of the Company, there are
not now and never have been any underground tanks or above-ground tanks located
on the Subject Premises; (iii) neither the Company nor any of the Subsidiaries,
nor, to the Company's best knowledge, any other Person has at any time during
its possession of the Subject Premises disposed of any wastes, Hazardous Waste
(as defined below) or otherwise, other than in accordance with applicable
Environmental Laws and Environmental Permits (as defined below); (iv) neither
the Company nor any of the Subsidiaries has received any letter or other
communication, written or oral, from the Federal Environmental Protection Agency
or any other local, state or Federal regulatory agencies or any other Person
relating to the existence of Environmental Defects at the Subject Premises; (v)
to the best knowledge of the Company, there do not exist any judgments, orders,
directives, decrees or awards of any court, arbitrator or 




                                      -16-
   17

administrative or governmental agency or entity or any other Person concerning
the Company or any of the Subsidiaries or any of their agents' or contractors'
compliance with any Environmental Law or Environmental Permit (in the case of
agents and contractors, relating to the Company, any of the Subsidiaries or the
Subject Premises); (vi) no claims have been asserted or, to the best knowledge
of the Company, are threatened against the Company or any of the Subsidiaries
relating to any Environmental Defect or condition which with the passage of time
could become an Environmental Defect; (vii) to the best knowledge of the
Company, there do not exist any consent decrees, administrative orders,
settlement agreements or other settlement documents entered into with any
administrative or governmental agency or entity or any other Person concerning
compliance with any Environmental Law or Environmental Permit applicable to the
Company or any Subsidiary or any of the Subject Premises; (viii) the Subject
Premises and all operations conducted thereon by the Company or any Subsidiary
are and have at all times been conducted in compliance in all material respects
with all Environmental Laws and Environmental Permits; (ix) the Company and each
Subsidiary have obtained and currently maintain in full force and effect all
environmental permits, approvals, authorizations, licenses, variances,
registrations and permissions (collectively, "Environmental Permits") required
for the conduct of their respective businesses and operations; and (x) to the
best knowledge of the Company, there are no Hazardous Substances or Hazardous
Waste on, under or about the Subject Premises other than those customarily used
in or incident to the business of the Company or any Subsidiary, which in any
event are used or maintained in all material respects in accordance with all
applicable Environmental Laws and Environmental Permits. For purposes hereof,
"Hazardous Substances" or "Hazardous Waste" are defined as any pollutant,
contaminant, chemical or industrial or toxic substance or waste, petroleum
products, asbestos, urea formaldehyde, radon, polychlorinated biphenyls,
flammable explosives, nuclear radioactive fuel or waste or any other substance,
waste, material, substance, pollutant or contaminant that is defined as a
hazardous waste or substance under any applicable Environmental Law or that may
cause damage to human health or the environment, safety or real property and/or
any substance for which the generation, manufacture, storage, treatment or
release is prohibited or regulated under any Environmental Law.

                  Section 3.24. Offering Valid. Assuming the accuracy of the
representations and warranties of the Purchaser contained in Article IV hereof,
the offer, sale and issuance of the Preferred Shares, the Warrants and the
Common Shares upon conversion of the Preferred Shares or exercise of the
Warrants, as applicable, will be exempt from the registration requirements of
the Securities Act and will have been registered or qualified (or are exempt
from registration and qualification) under the registration, permit or

Preferred Shares or Warrants to any Person or Persons or has taken or will take
any other action so as to bring the sale of such Preferred Shares, Warrants or

                  Section 4.1. Organization, Existence and Authority of
Purchaser; Enforceability. The Purchaser is a corporation duly incorporated,
validly existing and in good standing under the laws of the jurisdiction of its
incorporation. The Purchaser has all necessary corporate power and authority to
execute and deliver this Agreement, the Registration Rights Agreement and the
Shareholders Agreement, to consummate the transactions contemplated hereby and
thereby and to perform its obligations hereunder and thereunder. The execution
and delivery by the Purchaser of this Agreement, the Registration Rights
Agreement and the Shareholders Agreement, and the performance of its obligations
hereunder and thereunder, have been duly authorized by all necessary corporate
and other action, and no further authorization on the part of the Purchaser is
necessary to authorize such execution, delivery and performance. This Agreement
has been, and the Registration Rights Agreement and the Shareholders Agreement
when executed and delivered by the Purchaser will be, duly executed and
delivered by the Purchaser. This Agreement constitutes, and the Registration
Rights Agreement, the Warrant Certificate and the Shareholders Agreement, when
so executed and delivered, will constitute, legal, valid and binding agreements
of the Purchaser, enforceable against the Purchaser in accordance with their
respective terms, except as enforceability may be subject to the application of
general equitable principles and to bankruptcy, insolvency, moratorium or other
similar laws affecting creditors' rights generally.

                  Section 4.2. No Consent or Violation. No consent, approval or
authorization of, or declaration, filing or registration with, any governmental
or regulatory authority is required in connection with the execution and
delivery by the Purchaser of this Agreement, the Registration 




                                      -18-

Rights Agreement, the Warrant Certificate and the Shareholders Agreement, the
consummation of the transactions contemplated hereby and thereby and the
performance by the Purchaser of its obligations hereunder and thereunder. The
execution and delivery by the Purchaser of this Agreement, the Registration
Rights Agreement, the Warrant Certificate and the Shareholders Agreement, the
consummation of the transactions contemplated hereby and thereby and the
performance by the Purchaser of its obligations hereunder and thereunder do not
and will not (with the giving of notice or the passage of time or both) (a)
conflict with or violate or result in a breach of or constitute a default under,
or result in any right of termination by any other Person or the creation of any
Lien upon any properties or assets of the Purchaser pursuant to: (i) the
organizational documents of the Purchaser or (ii) any material note, bond,
mortgage, indenture, deed of trust, license, franchise, permit, lease, contract,
agreement or other instrument to which the Purchaser is a party or by which any
of its properties are bound or (b) violate any applicable law, rule, regulation,
judgment, injunction, order or decree binding upon the Purchaser or to which any
of its properties is subject.

                  Section 4.3. Purchase for Own Account. The Preferred Shares
and the Warrants to be acquired by the Purchaser pursuant to this Agreement will
be acquired for its own account for investment purposes and not with a view to
the resale or distribution of any part thereof.

                  Section 4.4 Restricted Securities. The Purchaser understands
that the Preferred Shares and the Warrants being acquired pursuant hereto are
characterized as "restricted securities" under the Federal and state securities
laws inasmuch as they are being acquired from the Company in a transaction not
involving a public offering and that under such laws and applicable regulations
such securities may be resold without registration under the Securities Act and
applicable state securities laws only in certain limited circumstances. The
Purchaser is familiar with Rule 144 ("Rule 144") of the Commission, as presently
in effect, and understands the resale limitations imposed thereby and by the
Securities Act and applicable state securities laws, pursuant to which the
Preferred Shares and the Warrants (and the Common Shares issuable upon
conversion of the Preferred Shares or exercise of the Warrants) must be held
indefinitely unless a subsequent disposition thereof is registered under the
Securities Act and applicable state securities laws or is exempt from such
registration.

                  Section 4.5. Accredited Investor. The Purchaser is an
"accredited investor" within the meaning of Rule 501(a) of Regulation D,
promulgated under the Securities Act, and was not organized for the specific
purpose of acquiring the Preferred Shares and the Warrants.

                  Section 4.6. Investor Sophistication. The Purchaser, by reason
of its business and financial experience, has such knowledge, sophistication and
experience in business and financial matters as to be capable of evaluating the
merits and risks of the prospective investment and is able to bear the economic
risk of such investment.

                  Section 4.7. Brokerage. No placement agent, banker, broker or
finder has acted directly or indirectly for the Purchaser in connection with
this Agreement or the transactions contemplated hereby, and no placement agent,
banker, broker or finder is entitled to any commission, brokerage or finder's
fee in respect thereof based in any way on agreements, arrangements or
understandings made by or on behalf of the Purchaser.

                                CERTAIN COVENANTS

the Preferred Shares and Warrants will be used by the Company for its working
capital needs.

                  Section 5.2. Certain Actions. From the date hereof through the
Closing Date, the Company (i) shall not, and shall cause each Subsidiary not to,
take any action that would cause any of the representations or warranties of the
Company set forth herein to become untrue or misleading and (ii) shall not take
any action which if taken after the Closing Date would require adjustment of the
conversion price of the Preferred Shares, adjustment of the exercise price of
the Warrants or adjustment of the number of Common Shares issuable upon
conversion of the Preferred Shares pursuant to the Certificate of Amendment or
upon exercise of the Warrants pursuant to the Warrant Certificate.

                                   ARTICLE VII
                                 INDEMNIFICATION

                  Section 7.1. General. (a) The Company (the "Indemnifying
Party") agrees and covenants to hold harmless and indemnify the Purchaser and
each of its Affiliates, and their respective managed accounts, shareholders,
employees, directors, officers, principals, equity holders, controlling Persons,
advisors and agents (each of the foregoing Persons being an "Indemnified
Person"), from and against any losses, claims, damages, liabilities and expenses
(including reasonable attorneys' fees and expenses of investigation) incurred by
such Indemnified Person (collectively, "Indemnifiable Costs and Expenses") in
connection with (i) any actual or threatened third-party action, suit,
proceeding or investigation arising out of or based in any manner upon the
Purchaser's negotiation, execution or performance of its obligations hereunder
or under the Registration Rights Agreement, the Warrant Certificate or the
Shareholders Agreement or its ownership of the Preferred Shares, the Warrants or
Common Shares, (ii) arising out of or based upon any breach by the Indemnifying
Party of any its representations, warranties or covenants contained herein, in
the Registration Rights Agreement, the Warrant Certificate or the Shareholders
Agreement or in any agreement, instrument or document delivered by the 




                                      -23-
   24

Company hereunder or thereunder or (iii) enforcing the rights of an Indemnified
Person under this Agreement or under the Registration Rights Agreement, the
Warrant Certificate or the Shareholders Agreement.

                  (b) The Indemnifying Party further agrees promptly upon demand
by each Indemnified Person to reimburse each Indemnified Person for any
Indemnifiable Costs and Expenses as they are incurred by it; provided that if
the Indemnifying Party reimburses an Indemnified Person hereunder for any
expenses incurred in connection with a lawsuit, claim, inquiry or other
proceeding or investigation for which indemnification is sought, such
Indemnified Person agrees to refund such reimbursement of expenses to the extent
it is finally judicially determined that the indemnity provided for in this
Article VII is not applicable to such Indemnified Person in accordance with the
terms hereof or otherwise. The Indemnifying Party further agrees that the
indemnification, contribution and reimbursement commitments set forth in this
Article VII shall apply whether or not an Indemnified Person is a formal party
to any such lawsuits, claims or other proceedings. The indemnity, contribution
and expense reimbursement obligation of the Indemnifying Party under this
Article VII shall be in addition to any liability it may otherwise have.

                  (c) The obligations of the Indemnifying Party hereunder shall
survive the Closing and any repurchase, conversion, exchange or transfer of the
Preferred Shares or Warrants and the termination of this Agreement and shall not
be extinguished with respect to any Person because any other Person is not
entitled to indemnity or contribution hereunder.

                  Section 7.2 Procedure. Promptly after receipt by an
Indemnified Person of notice from any third party of the commencement of any
lawsuit, inquiry or other proceeding or investigation thereof, such Indemnified
Person will, if a claim in respect thereof is to be made against the
Indemnifying Party hereunder, notify the Indemnifying Party in writing of the
commencement thereof; but the omission so to notify the Indemnifying Party will
not relieve the Indemnifying Party (x) from any liability which it may have to
any Indemnified Person hereunder unless the Indemnifying Party is actually
prejudiced thereby or (y) from any liability which it may have to any
Indemnified Person otherwise than pursuant to this Article VII. Each Indemnified
Person shall permit the Indemnifying Party to assume the defense of such claim
with counsel reasonably satisfactory to such Indemnified Person; provided,
however, that any Indemnified Person shall have the right to employ separate
counsel and to participate in the defense of such claim, but the fees and
expenses of such counsel shall be at the expense of such Indemnified Person
unless (A) the Indemnifying Party has agreed to pay such fees or expenses, (B)
the Indemnifying Party shall have failed to assume the defense of such claim and
employ counsel reasonably satisfactory to such Indemnified Person in a timely
manner or (C) in the reasonable judgment of such Indemnified Person, based upon
advice of its counsel, a conflict of interest may exist between such Indemnified
Person and the Indemnifying Party with respect to such claims (in which case, if
such Indemnified Person notifies the Indemnifying Party in writing that such
Indemnified Person elects to employ separate counsel at the expense of the
Indemnifying Party, 




                                      -24-
   25
the Indemnifying Party shall not have the right to assume the defense of such
claim on behalf of such Indemnified Person). The Indemnifying Party will not be
subject to any liability for any settlement made without its consent (but such
consent will not be unreasonably withheld or delayed). No Indemnified Person
will be required to consent to entry of any judgment or enter into any
settlement which does not include as an unconditional term thereof the giving by
the claimant or plaintiff to such Indemnified Person of a release from all
liability in respect of such claim or litigation. An Indemnifying Party who is
not entitled to, or elects not to, assume the defense of a claim will not be
obligated to pay the fees and expenses of more than one counsel for all
Indemnified Persons with respect to such claim, as well as one local counsel in
each relevant jurisdiction.

                  Section 7.3. Contribution. (a) In order to provide for just
and equitable contribution in circumstances under which the indemnity provided
for in this Article VII is for any reason held to be unenforceable by the
Indemnified Person, the Indemnifying Party, in lieu of indemnifying such
Indemnified Person, shall have an obligation to contribute, and shall contribute
to the amount paid or payable by such Indemnified Person as a result of such
losses, claims, damages, liabilities or expenses in such proportion as is
appropriate to reflect not only the relative benefits received by the
Indemnifying Party and the Indemnified Persons, but also to reflect the relative
fault of the Indemnifying Party and the Indemnified Persons in connection with
the statement or omissions which result in such losses, claims, damages,
liabilities or expenses, as well as any other relevant equitable considerations;
provided, however, that no Person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any Person who was not guilty of such fraudulent
misrepresentation. The relative fault of the Indemnifying Party and the
Indemnified Persons shall be determined, if applicable, by reference to, among
other things, whether the untrue statement of a material fact or the omission to
state a material fact has been made by, or relates to information supplied by,
the Indemnifying Party or Indemnified Persons and the Persons' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission. The amount paid or payable by a Person as a result of the
losses, claims, damages, liabilities and expenses referred to above shall be
deemed to include any reasonable legal or other fees or expenses reasonably
incurred by such Person in connection with investigation or defending any such
claim.

                  (b) The Company and the Purchaser agree that it would not be
just and equitable if contribution pursuant to the immediately preceding
paragraph were determined by any method of allocation which does not take into
account the equitable considerations referred to in such paragraph.

                  Section 7.4. Notification. Each party agrees to notify in
writing promptly the other party of the commencement of any litigation or
proceeding against it or any of its shareholders, officers, directors or agents
in connection with the issue of any the Preferred Shares, Warrants or Common
Shares.

                  Section 8.1. Entire Agreement; Survival of Provisions. This
Agreement, together with the other agreements, instruments and documents
expressly referred to herein, constitute the entire agreement of the parties
with respect to the transactions contemplated hereby and supersede all prior
agreements and understandings with respect thereto, whether written or oral. All
of the covenants of the parties made herein shall remain operative and in full
force and effect regardless of acceptance of any of the Preferred Shares or
Warrants and payment therefor. The representations and warranties set forth
herein shall survive the execution and delivery of this Agreement, the issuance
of the Preferred Shares and the Warrants, the Closing and the issuance of the
Common Shares upon conversion of the Preferred Shares or exercise of the
Warrants, as applicable, and shall in no way be affected by any investigation of
the subject matter thereof made by or on behalf of the Purchaser or the Company.
The representations, warranties, agreements and covenants made herein and in the
Registration Rights Agreement, the Warrant Certificate and the Shareholders
Agreement shall be deemed to have been relied upon by the parties hereto.

                  Section 8.2. No Waiver; Modifications in Writing. No failure
or delay by a party in exercising any right, power or remedy hereunder shall
operate as a waiver thereof, nor shall any single or partial exercise of any
such right, power or remedy preclude any other or further exercise thereof or
the exercise of any other right, power or remedy. The remedies provided for
herein are cumulative and are not exclusive of any remedies that may be
available to any party at law or in equity or otherwise. No waiver of or consent
to any departure by a party from any provision of this Agreement shall be
effective unless signed in writing by the parties entitled to the benefit
thereof. No amendment, modification or termination of any provision of this
Agreement shall be effective unless signed in writing by all parties. Any
amendment, supplement or modification of or to any provision of this Agreement,
any waiver of any provision of this Agreement, and any consent to any departure
from the terms of any provision of this Agreement, shall be effective only in
the specific instance and for the specific purpose for which made or given.

the Board of Directors of the Company or any of its Subsidiaries of which such

Subsidiary or as a committee member of the Board of Directors of the Company or
any such Subsidiary, to the extent not accounted for in clause (x) above.

that it shall not permit any increase in the number of directors on the Board of
Directors of the Company beyond such number of directors at the Effective Date
(after accounting for the director to be designated by the holders of Series A
Preferred Stock on the Effective Date pursuant to Section 2.1 hereof and the
Certificate of Incorporation), unless the prior written consent of the Investor
is obtained prior thereto, which consent shall not be unreasonably withheld or
delayed.


                                   ARTICLE III

                    AGREEMENTS RELATING TO THE CAPITAL STOCK

the Effective Date and ending on the date that is two years thereafter (the
"Restricted Period"), the Existing Shareholders severally agree with the
Company, the Investor and with each other Shareholder that they will not,
directly or indirectly, Transfer any Capital Stock of the Company (or any
interest therein), now or hereafter at any time owned by them, except that each
Existing Shareholder may Transfer, upon written notice to the Company, the
Investor and each other Shareholder, in accordance with applicable law: (i) any
Common Stock of the Company pursuant to an Involuntary Transfer; (ii) any Common

which is for the benefit of such Existing Shareholder or such Existing
Shareholder's spouse, parents, siblings, children, stepchildren or
grandchildren; (iii) during the period from (and including) the Effective Date
through (but excluding) the date that is one year thereafter (the "Initial
Period"), any Common Stock which does not exceed five percent (5%) of all of the
Common Stock held by such Existing Shareholder on the Effective Date; and (iv)
during the 



                                      - 6 -

   7
period from (and including) the last day of the Initial Period through (and
including) the last day of the Restricted Period, any Common Stock which does
not exceed fifteen percent (15%) of all of the Common Stock held by such
Existing Shareholder on the Effective Date; provided, however, that, in
connection with any Transfer permitted under this Section 3.1(a), prior to such
Transfer, such Existing Shareholder shall comply with Section 3.1(b) hereof.

                  (b) Any Transfer of Capital Stock of the Company by any
Existing Shareholder during the Restricted Period or at any time thereafter to a
Related Transferee shall not relieve the transferor of its obligations hereunder
and shall only be valid if the Person to whom such Capital Stock is Transferred
(a "Transferee"), prior to the Transfer, agrees in writing to be bound by the
terms of this Agreement as and to the same extent that the transferor
was bound by this Agreement immediately prior to such Transfer. Any such
Transferee that agrees to be bound by the terms of this Agreement as provided in
this paragraph (b) shall be deemed, upon execution and delivery of such
agreement, to be a Shareholder hereunder. Each such Transferee shall be entitled
to all of the rights under this Agreement to which the transferor was entitled
immediately prior to such Transfer. Any purported Transfer without obtaining
this agreement by the Transferee shall be deemed void and of no further effect
and shall be governed by the provisions of paragraph (c) below. The provisions
of this paragraph (b) shall not apply in connection with a Public Transfer by an
Existing Shareholder.

                  (c) In the event a Transfer of any Capital Stock of the
Company has taken place or remains in place in violation of the provisions of
this Article III, such Transfer shall be void and of no effect, and no dividend
of any kind whatsoever nor any distribution pursuant to liquidation or otherwise
shall be paid by the Company or the related Shareholder to the Transferee in
respect of such Capital Stock (all such dividends and distributions being deemed
waived), and any voting rights of such Capital Stock on any matter whatsoever
shall remain vested in the transferor.

                  (d) The provisions of this Section 3.1 shall be in addition
to, and shall not in any way limit the application of, any other provision of
this Agreement.

                  2   TAG-ALONG RIGHTS. (a) If, at any time, any Existing
Shareholder and/or a Related Transferee or Related Transferees of such Existing
Shareholder (a "Section 3.2 Transferor") desires to Transfer any of its Common
Stock in an amount in excess of fifteen percent (15%) of all of the Common Stock
held by such Existing Shareholder on the Effective Date in one transaction or a
series of transactions to any Person or Persons (a "Section 3.2 Transferee"),
except pursuant to an Exempt Transfer or a Public Transfer, prior to any such
Transfer, such Section 3.2 Transferor shall promptly (and in any event at least
20 business days prior to the closing date thereof), provide each Investor
Holder (each, a "Prospective Participating Shareholder") with written notice of
the proposed Transfer (the "Transfer Notice") containing the following:

                  (i)      the name and address of the proposed Section 3.2 
         Transferee;


                                      - 7 -


   8
                  (ii)     the number of shares of Common Stock to be 
         Transferred by such Section 3.2 Transferor; and

                  (iii)    the purchase price and other terms and conditions of
         payment and the closing date for the proposed Transfer (including, when
         available, a copy of any purchase agreement related thereto).

                  (b) If any of such Prospective Participating Shareholders
(each, a "Participating Shareholder") wishes to participate in such Transfer,
each such Participating Shareholder may notify the Section 3.2 Transferor by
written notice (the "Tag-Along Notice") on or before the expiration of 15
business days following receipt of the Transfer Notice that such Participating
Shareholder desires to Transfer to the proposed Section 3.2 Transferee a part of
its shares of Capital Stock of the Company (as determined pursuant to the
following sentence) on the same terms and conditions set forth in the Transfer
Notice. The Tag-Along Notice shall specify the number of shares of such Capital
Stock such Participating Shareholder desires to Transfer (the "Tag-Along
Amount"); for purposes of making any determination or calculation pursuant to
this Section 3.2, but for such purposes only, as of any date of determination or
calculation, all of the Capital Stock of the Company held by an Investor Holder
shall be deemed to have been fully converted, exercised or exchanged, to the
extent applicable, as of such date of determination or calculation. The maximum
number of shares of such Capital Stock that each such Participating Shareholder
separately shall be entitled to Transfer hereunder shall be determined by
multiplying the number of shares of such Capital Stock held by such
Participating Shareholder at the time of the Transfer Notice by a fraction, the
numerator of which is the number of shares of Common Stock proposed to be
Transferred to the Section 3.2 Transferee by the Section 3.2 Transferor and the
denominator of which is the number of shares of Common Stock then owned by the
Section 3.2 Transferor. If no Prospective Participating Shareholder provides the
Section 3.2 Transferor with a Tag-Along Notice within the period specified
above, the Section 3.2 Transferor shall be free to sell all or a portion of such
Common Stock to the Section 3.2 Transferee in the amount and on the same terms
and conditions set forth in the Transfer Notice, subject to paragraph (h) below.
If there is any Participating Shareholder(s), the Section 3.2 Transferor may not
effect such Transfer unless the Section 3.2 Transferee shall have purchased the
Tag-Along Amount or the Reduced Tag-Along Amount (as defined below) from each
such Participating Shareholder on the same terms and conditions set forth in the
Transfer Notice.

                  (c) If the sum (the "Aggregate Shares Offered") of (i) the
number of shares of Common Stock proposed to be Transferred to the Section 3.2
Transferee by the Section 3.2 Transferor and (ii) the aggregate Tag-Along
Amounts for all Participating Shareholders exceeds the number of shares of
Common Stock that such Section 3.2 Transferee is willing to purchase, then each
such Participating Shareholder shall be obligated to Transfer a number of shares
of Common Stock or its equivalent (the "Reduced Tag-Along Amount") equal to the
product of the number of shares of Common Stock which the Section 3.2 Transferee
is willing to purchase and a fraction, the numerator of which is the Tag-Along
Amount with respect to such Person and the denominator of which is the Aggregate
Shares Offered, and the Section 3.2 Transferor shall be obligated to Transfer a
number of shares of Common Stock equal to the number of shares of 




                                      - 8 -

   9
Common Stock which the Section 3.2 Transferee is willing to purchase minus the
Reduced Tag-Along Amount or Reduced Tag-Along Amounts for all Participating
Shareholders.

                  (d) Any indemnity provided by a Participating Shareholder to
the Section 3.2 Transferee in a purchase agreement relating to such Transfer
will only relate to the shares of Capital Stock Transferred by it. Any indemnity
provided to the Section 3.2 Transferee by the Section 3.2 Transferor will only
relate to the shares of Common Stock Transferred by it.

                  (e) The Section 3.2 Transferor and the Participating
Shareholders whose shares of Capital Stock are Transferred pursuant to this
Section 3.2 shall be required to bear their pro rata share, based on the number
of shares of Capital Stock included in such Transfer, of the expenses of the
transaction including, without limitation, legal, accounting and investment
banking fees and expenses.

                  (f) The Company shall, upon request by any Participating
Shareholder, issue to such Participating Shareholder one or more stock
certificates registered in the names and in the denominations (aggregating in a
number equal to the original denomination) requested by such Participating
Shareholder, to facilitate any partial sale of shares of any Capital Stock
pursuant to this Section 3.2.

                  (g) To the extent that any prospective Section 3.2 Transferee
is unwilling or otherwise refuses to purchase Capital Stock from any
Participating Shareholder, the Section 3.2 Transferor shall not Transfer to such
prospective Section 3.2 Transferee any Common Stock, unless and until,
simultaneously with such Transfer, the Section 3.2 Transferor shall purchase
such Capital Stock from such Participating Shareholder on the same terms and
conditions specified in the Transfer Notice.

                  (h) Subject to the rights of each Prospective Participating
Shareholder, if it has so elected, to participate in the Transfer of Common
Stock as provided in this Section 3.2, the Section 3.2 Transferor may, not later
than sixty (60) days following delivery to the Prospective Participating
Shareholders of the Transfer Notice, conclude a Transfer of Common Stock covered
by the Transfer Notice on the terms and conditions described in the Transfer
Notice. Any proposed Transfer on terms and conditions more favorable to the
Section 3.2 Transferee than those described in the Transfer Notice, as well as
any proposed Transfer of any Common Stock by the Section 3.2 Transferor more
than sixty (60) days following delivery to the Prospective Participating
Shareholders of the Transfer Notice, shall again be subject to the tag-along
rights of the Prospective Participating Shareholders and shall require
compliance by the prospective Section 3.2 Transferor with the procedures
described in this Section 3.2.

                  (i) The exercise or non-exercise of the rights of any
Prospective Participating Shareholder under this Section 3.2 to participate in
one or more Transfers of Common Stock shall not adversely affect its right to
participate in subsequent Transfers of Common Stock pursuant to this Section
3.2.



                                      - 9 -

                  (j) The provisions of this Section 3.2 shall be subject in all
respects to the provisions of Section 3.1 hereof (except as otherwise set forth
herein).

                  (k) This Section 3.2 shall remain in effect only so long as at
least 250,000 shares of Series A Preferred Stock are outstanding (as adjusted
for stock splits, stock dividends, stock combinations, recapitalizations and
like occurrences).

                  3   NO ISSUANCE OF CAPITAL STOCK. For the period beginning on
the Effective Date and ending nine (9) months thereafter, the Company shall not
issue or Transfer any of its Capital Stock without the Investor's prior written
consent, except for the issuance by the Company of shares of Common Stock (or,
in the case of clause (i) below, options to purchase Common Stock) in connection
with (i) the Stock Option Issuance (provided that during such nine (9)-month
period, such issuances shall not exceed options to purchase up to 225,000 shares
of Common Stock and the issuance of Common Stock upon the exercise of such
options and provided, further, that no such options or shares of Common Stock
may be issued by the Company prior to January 1, 1997), (ii) the conversion of
the Series A Preferred Stock or the exercise of the Warrants or (iii) the
exercise of warrants or options that are outstanding as of the Effective Date
and which are specified in Section 3.2 of the Purchase Agreement.

                  4   PARTICIPATION RIGHT ON NEW SECURITIES. During the
Restricted Period, the Company hereby grants to each of the Investor Holders
(collectively, the "Eligible Holders") the right of first refusal to purchase a
pro rata share of New Securities (as defined below) that the Company may, from
time to time, propose to sell and issue (the "Participation Right"). Each
Eligible Holder's pro rata share, for purposes of this Participation Right, is
the ratio of (X) the number of shares of Common Stock then owned by such
Eligible Holder to (Y) the total number of shares of Common Stock of the Company
outstanding immediately prior to the issuance of the New Securities, assuming,
in each case but for purposes of this Section 3.4 only, full conversion of all
shares of then outstanding Series A Preferred Stock and full exercise of all
then outstanding Warrants and other rights, options and warrants to purchase or
acquire Common Stock. This Participation Right shall be subject to the following
provisions:

                           (a)      "New Securities" shall mean any offering by 
the Company of any Capital Stock of the Company, whether now authorized or not;
provided, however, that "New Securities" does not include (i) Common Stock
issued pursuant to the Stock Option Issuance; (ii) Common Stock issuable upon
conversion of the Series A Preferred Stock or upon exercise of the Warrants;
(iii) Capital Stock issued pursuant to the acquisition of another corporation by
the Company by merger, purchase of substantially all of the assets or other
reorganization, whereby the Company owns more than 50% of the voting power of
such corporation; and (iv) Common Stock issuable upon the exercise of warrants
or options that are outstanding as of the Effective Date and which are specified
in Section 3.2 of the Purchase Agreement.

                           (b)      In the event that the Company proposes to 
undertake an issuance of New Securities, it shall give each Eligible Holder
written notice of its intention, describing the type of New Securities, the
price and the general terms and conditions upon which the Company 




                                     - 10 -
   11
proposes to issue the same. Each Eligible Holder shall have twenty (20) business
days from the date of receipt of any such notice to agree to purchase its pro
rata share of such New Securities for the price and upon the general terms and
conditions specified in the notice by giving written notice to the Company and
stating therein the quantity of New Securities to be purchased.

                           (c)      In the event that the Eligible Holders fail
to exercise in full the Participation Right within said twenty (20) business day
period, the Company shall have sixty (60) days thereafter to sell the New
Securities respecting which the Eligible Holders' Participation Rights were not
exercised at a price and upon terms and conditions no more favorable to the
purchasers thereof than specified in the Company's notice. In the event the
Company has not sold the New Securities within said sixty (60) day period, the
Company shall not thereafter issue or sell any New Securities without first
offering such securities to the Eligible Holders in the manner provided above.

                           (d)      This Section 3.4 shall not limit in any 
respect the obligations of the Company under Section 3.3.




                           (e)      This Section 3.4 shall remain in effect only
so long as at least 250,000 shares of Series A Preferred Stock are outstanding
(as adjusted for stock splits, stock dividends, stock combinations,
recapitalizations and like occurrences).

                  5   LEGENDS ON STOCK. Each Capital Stock certificate of the
Company held by an Existing Shareholder or any Transferee of an Existing
Shareholder shall bear the following legend on the face thereof:

                  "THIS CERTIFICATE IS ISSUED SUBJECT TO THE PROVISIONS OF A
         SHAREHOLDERS AGREEMENT DATED AS OF DECEMBER 20, 1996, AND NEITHER THIS
         CERTIFICATE NOR THE SHARES REPRESENTED BY IT ARE ASSIGNABLE OR
         OTHERWISE TRANSFERABLE, EXCEPT IN ACCORDANCE WITH THE PROVISIONS OF
         SAID AGREEMENT, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE
         COMPANY."

                  "THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN
         REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR
         ANY STATE SECURITIES LAWS AND MAY NOT BE OFFERED, SOLD OR OTHERWISE
         TRANSFERRED UNLESS REGISTERED UNDER THE ACT AND ANY APPLICABLE STATE
         SECURITIES LAW OR UNLESS AN EXEMPTION FROM SUCH REGISTRATION IS
         AVAILABLE."

Any certificate issued at any time in exchange or substitution for any
certificate bearing such legend (except a new certificate issued upon completion
of a public distribution under a registration statement of the Capital Stock
represented thereby) shall also bear such legend unless, in the opinion of
counsel for the holder of such Capital Stock (which counsel shall be reasonably




                                     - 11 -
   12
satisfactory to the Company), the Capital Stock represented thereby is not, at
such time, required by law to bear such legend. The Company agrees that it will
not Transfer on its books any certificate for its Capital Stock in violation of
the provisions of this Agreement.

                           (a)   Authority.  Each Existing Shareholder has all
requisite power to enter into this Agreement and to consummate the transactions 
contemplated hereby. This Agreement and each of the Related Documents to which 
it is a party have been duly executed and delivered by each Existing 
Shareholder, have been effectively authorized by all necessary action

and to bankruptcy, insolvency, moratorium or other similar laws affecting
creditors' rights generally.

                           (b)   Agreements Not in Breach of Other Instruments. 
The execution and delivery of this Agreement and the Related Documents to which
it is a party, the consummation of the transactions contemplated hereby and
thereby and the fulfillment of the terms hereof and thereof will not result in a
breach of any of the terms or provisions of, or constitute a default under, or
conflict with (x) any agreement, indenture or other instrument to which any
Existing Shareholder is a party or by which it is bound, (y) any judgment,
decree, order or award of any court, governmental body, Governmental Authority
or arbitrator by which any Existing Shareholder is bound or (z) any Requirement
of Law applicable to any Existing Shareholder.

                           (c)  Regulatory Approvals.  There are no consents, 
approvals, authorizations or other requirements prescribed by any applicable
Requirement of Law that must be obtained or satisfied in connection with the
Existing Shareholder's execution, delivery and performance of this Agreement or
any of the Related Documents to which it is a party.

                           (d)    No Legal Bar.  Except as set forth on Schedule
4.1(d) hereto, there is no suit, action or proceeding pending or, to each
Existing Shareholder's knowledge, threatened against any Existing Shareholder
that questions the validity of this Agreement or any of the Related Documents,

been taken by any of the parties in connection herewith or therewith or in
connection with any of the transactions contemplated hereby or thereby or that
seeks to enjoin the consummation thereof.

                           (e)    No Brokerage Fees.  No broker or finder has 
acted for any Existing Shareholder in connection with this Agreement or any of
the Related Documents or the transactions contemplated hereby or thereby, and no
broker or finder is entitled to any brokerage or finder's fees or other
commission in respect of such transactions based in any way on agreements,
arrangements or understandings made by or on behalf of any Existing Shareholder.

                           (f)   Capitalization of the Company.  As of the 
Effective Date, each of the Existing Shareholders owns all right, title and
interest in and to the number of shares of Common Stock and the number of
options exercisable for Common Stock, respectively, specified with respect to
such individual on Schedule I attached hereto, free and clear of all liens,
claims, charges, security interests and other encumbrances, and such shares, as
of the Effective Date, represent the percentage ownership of all of the Capital
Stock of the Company on a fully diluted basis (assuming, for this purpose only,
that all Capital Stock of the Company that is convertible or exercisable into or
exchangeable for Common Stock has been so converted, exercised or exchanged in
full) as specified with respect to such individual on Schedule I. As of the
Effective Date, no shares of Capital Stock of the Company are owned by any
Existing Shareholder other than as specified on Schedule I with respect to such
Existing Shareholder.

                  2        REPRESENTATIONS AND WARRANTIES OF OTHER SHAREHOLDERS.
Each Shareholder (other than an Existing Shareholder and the Investor) hereby
makes the representations and warranties of the Existing Shareholders set forth
in Section 4.1(b), (c), (d) and (e) and the representation and warranty set
forth below, in each case with respect to itself only, to the Company and each
other Shareholder.

                           (a)   Organization and Authority.  To the extent the 
Shareholder is a Person other than an individual, it is a company duly
organized, validly existing and in good standing under the laws of its
jurisdiction of organization, has all requisite power and authority to enter
into this Agreement and to consummate the transactions contemplated hereby, and
is duly qualified as a foreign company under the laws of each jurisdiction where
its conduct of business or the ownership of its assets requires such
qualification. To the extent the Shareholder is an individual, it has all
requisite power to enter into this Agreement and to consummate the transactions
contemplated hereby. This Agreement has been duly executed and delivered by such
Person, has been effectively authorized by all necessary action, and constitutes
the legal, valid and binding obligation of such Person, enforceable against such
Person in accordance with its terms, except as enforceability may be subject to
the application of general equitable principles and to bankruptcy, insolvency,
moratorium or other similar laws affecting creditors' rights generally.

                  3   CERTAIN ADDITIONAL REPRESENTATIONS OF THE SHAREHOLDERS.
Each Shareholder represents and warrants to the Company and to each other
Shareholder that (i) all Capital Stock of the Company purchased or otherwise
acquired by such Shareholder has been or is being acquired by it for its own
account for investment, without any intention of Transferring or further
distributing the same in violation of the securities laws and (ii) it is fully
aware that in agreeing to Transfer or issue such Capital Stock to it the Company
or a Shareholder, as applicable, is relying upon the truth and accuracy of this
representation and warranty.

registration or approval, as the case may be.

securities exchange or eligible for trading on NASDAQ (or any other quotation
system operated by a national securities association), the Company covenants and
agrees that it shall take all such action as may be necessary to cause all
shares reserved for such issuance to be listed as expeditiously as reasonably
possible on such exchange or to be made so eligible as expeditiously as possible

                  7   CONSENT TO JURISDICTION AND SERVICE OF PROCESS. Any suit,
action or proceeding arising out of or relating to this Agreement, the Related
Documents or the transactions contemplated hereby or thereby may be instituted
in any Federal court situated in the State of New York or any state court of the
State of New York in each case, in the Borough of Manhattan, City of New York,
and each party agrees not to assert, by way of motion, as a defense or
otherwise, in any such suit, action or proceeding, any claim that it is not
subject personally to the jurisdiction of such court, that the suit, action or
proceeding is brought in an inconvenient forum, that the venue of the suit,
action or proceeding is improper or that this Agreement, the Related Documents
or the subject matter hereof or thereof may not be enforced in or by such court.
Each party further irrevocably submits to the jurisdiction of such court in any
such suit, action or proceeding. Any and all service of process and any other
notice in any such suit, action or proceeding shall be effective against any
party if given personally or by registered or certified mail, return receipt

fully prepaid, 




                                     - 22 -
   23
mailed to such party as herein provided. Nothing herein contained shall be
deemed to affect the right of any party to serve process in any manner permitted
by law or to commence legal proceedings or otherwise proceed against any other
party in any other jurisdiction.

                  8   FURTHER ASSURANCES. Each of the parties hereto shall
execute and deliver such documents, instruments and agreements and take such
further actions as may be reasonably required or desirable to carry out the
provisions of this Agreement, the Related Documents and the transactions
contemplated hereby and thereby, and each of the parties hereto shall cooperate
with each other in connection with the foregoing.

                  9   SPECIFIC PERFORMANCE. The parties acknowledge that
irreparable damage would occur to the Investor in the event that any of the
provisions of this Agreement or any of the Related Documents were not performed
by the other parties hereto in accordance with their specific terms or were
otherwise breached by such other parties and that money damages would not
provide an adequate remedy to the Investor. It is accordingly agreed that the
Investor shall be entitled to an injunction and other equitable remedies to
prevent breaches by the other parties hereto of this Agreement and the Related
Documents, and to enforce specifically the terms and provisions hereof or
thereof in any court of the United States or any state thereof having
jurisdiction, this being in addition to any other remedy to which the Investor
may be entitled at law or in equity.

                  10   SEVERABILITY OF PROVISIONS. Any provision of this
Agreement which is prohibited or unenforceable in any jurisdiction shall, as to
such jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof or
affecting the validity or enforceability of such provision in any other
jurisdiction. If any provision in Section 5.2 hereof is held to be invalid or
unenforceable because of the scope or duration of or the area covered by such
provision, the parties hereto agree that the court making such determination
shall reduce the scope, duration and/or area of such provision (and shall
substitute appropriate provisions for any such invalid or unenforceable
provisions) in order to make such provision enforceable to the fullest extent
permitted by law and/or shall delete specific words and phrases, and such
modified provision shall then be enforceable and shall be enforced. The parties
hereto recognize that if, in any judicial proceeding, a court shall refuse to
enforce any of the separate covenants contained in Section 5.2 hereof, then that
invalid or unenforceable covenant contained in Section 5.2 hereof shall be
deemed eliminated from this Agreement to the extent necessary to permit the
remaining separate covenants hereof to be enforced. In the event that any court
determines that the time period or the area, or both, are unreasonable and that
any of the covenants in Section 5.2 hereof is to that extent invalid or
unenforceable, the parties hereto agree that such covenants will remain in full
force and effect, first, for the greatest time period, and second, in the
greatest geographical area that would not render them enforceable.

                  11   HEADINGS. The Article and Section headings used or
contained in this Agreement are for convenience of reference only and shall not
affect the construction of this Agreement.

                  12   COSTS AND EXPENSES. The respective parties hereto shall
pay all costs and expenses that each respectively incurs with respect to the
negotiation, execution and delivery of this Agreement and the Related Documents.

                  13   WAIVER OF JURY TRIAL. The parties hereto hereby
irrevocably waive all right to a trial by jury in any action, proceeding or
counterclaim arising out of or relating to this Agreement, the Related Documents
or the transactions contemplated hereby or thereby.

                  14   PUBLICITY. The parties agree that no public release or
announcement concerning this Agreement or any of the Related Documents or the
transactions contemplated hereby or thereby shall be made without advance review
and approval by the Company and the Investor, except as otherwise required by
applicable law.

                  15   NATURE OF AGREEMENTS. The covenants and agreements of the
parties in this Agreement are several and not joint covenants and agreements,
unless otherwise expressly specified herein.

                  SECTION 2. SECURITIES SUBJECT TO THIS AGREEMENT. The
securities entitled to the benefits of this Agreement are the Registrable
Securities but, with respect to any particular Registrable Security, only so
long as such security continues to be a Restricted Security. A Registrable
Security that has ceased to be a Registrable Security cannot thereafter become a
Registrable Security. As used herein, a "Restricted Security" is a Registrable
Security which has not been effectively registered under the Securities Act and
distributed to any Person in accordance with an effective Registration Statement
and which has not been distributed by a Holder to any Person pursuant to Rule
144.


                                      - 3 -

   4
                  SECTION 3.  DEMAND REGISTRATION.

                  (a) Demand. Upon the written request of the Securityholder or
a Holder or Holders of a majority of the then outstanding Registrable Securities
(on a Common Stock equivalent basis) requesting that the Company effect the
registration under the Securities Act of Registrable Securities and specifying
the intended method or methods of disposition thereof (which may include a
continuous or delayed offering), the Company will use its best efforts to
effect, as expeditiously as possible, the registration under the Securities Act
of the Registrable Securities which the Company has been so requested to
register by the Securityholder or such Holder or Holders of Registrable
Securities; provided, however, that, except as provided below, the Company shall
not be obligated to (1) effect more than an aggregate of two (2) demand
registrations pursuant to this Section 3; or (2) effect a demand registration
unless either (I) the Registrable Securities for which the demand is made
constitute at least one-half of the then outstanding Registrable Securities (on
a Common Stock equivalent basis) or (II) the demand is made with respect to all
of the Registrable Securities then beneficially owned by the Securityholder or
the demanding Holder or Holders, provided such Registrable Securities constitute
at least 10% of the Registrable Securities initially issued by the Company (on a
Common Stock equivalent basis); and provided further that no Holder (including
the Securityholder) shall deliver a request for a demand registration for a
period of four (4) months following the last date on which a Registration
Statement filed in respect of the previous demand registration, if any, was
declared by the SEC to be effective. The number, percentage or kind of shares in
clause (2) above shall be appropriately adjusted for any stock dividend, stock
split, reverse stock split, combination, recapitalization, reclassification,
merger, consolidation, exchange, distribution or similar transaction with
respect to the shares of Common Stock. Notwithstanding the foregoing, the
Securityholder or a Holder or Holders of a majority of the then outstanding
Registrable Securities (on a Common Stock equivalent basis) shall be entitled to
unlimited additional demand registrations if such additional demand
registrations would be eligible for registration on Form S-3 (after the Company
qualifies for Form S-3, provided that in the case of any individual such demand
registration the aggregate gross proceeds from such S-3 demand registration
would exceed $500,000, if all registered shares thereunder were sold); provided,
however, that there shall be no more than two (2) such registrations in any
twelve (12) month period.

                  Upon receipt of any request for registration pursuant to this
Section 3 from the Securityholder or any Holder or Holders of Registrable
Securities, the Company shall promptly (but in any event within 20 days) give
written notice of such request to all other Holders. The Company shall include
in the requested registration all Registrable Securities requested to be
included by such of the other Holders who shall make such request by written
notice to the Company delivered within 30 days of their receipt of the Company's
notice. If the Company shall receive a request for inclusion in the registration
of the Registrable Securities of additional Holders, it shall promptly so inform
in writing the Person or Persons who made the initial request for registration.
Notwithstanding the foregoing, if the managing underwriter or underwriters of
the proposed public offering advises the Holder or Holders intending to
participate in such proposed public offering in writing that the total amount or
kind of securities which such Holder 



                                      - 4 -


   5
or Holders intends to include in such proposed public offering is sufficiently
large to materially adversely affect the success of the proposed public
offering, then the amount or kind of securities to be offered for the accounts
of all Holders whose securities are included in such Registration Statement
shall be reduced (on a pro rata basis in the case of more than one such Holder)
to the extent necessary to reduce the total amount or kind of securities to be
included in such proposed public offering to the amount or kind recommended by
such managing underwriter or underwriters. The Company shall not register any
securities other than Registrable Securities in any demand registration effected
pursuant to this Section 3(a), except pursuant to Section 3(c) or with the prior
written consent of the Securityholder (if it is participating in such offering)
or, if the Securityholder is not participating in such offering, the Holders of
a majority of the Registrable Securities (on a Common Stock equivalent basis)
being sold pursuant to such offering.

                  A Holder (including the Securityholder) or Holders requesting
a registration pursuant to this Section 3 may, at any time prior to the
effective date of the Registration Statement relating to such registration,
revoke such request by providing a written notice to the Company revoking such
request. The Company shall be required to pay all Registration Expenses with
respect to the first demand for registration to be revoked. If a Holder
(including the Securityholder) or Holders thereafter shall revoke any demand for
registration, such Holder (including the Securityholder) or Holders, at their
option, shall either pay all out-of-pocket Registration Expenses with respect to
such revoked demand or count such revoked demand as one of the demands for
registration to which Holders are entitled pursuant to this Section 3.

                  (b) Effectiveness of Registration Statement. The Company
agrees to use its best efforts to (i) cause the Registration Statement relating
to any demand registration pursuant to this Section 3 to become effective as
expeditiously as possible; (ii) thereafter keep such Registration Statement
effective continuously for the period specified in the next succeeding paragraph
and to permit the sale of such Registrable Securities in accordance with the
intended method or methods of distribution thereof; and (iii) prevent the
happening of any event of the kinds described in clauses (4), (5) and (6) of
Section 5(a)(ii).

                  A demand registration requested pursuant to this Section 3
will not be deemed to have been effected unless the Registration Statement
relating thereto has become effective under the Securities Act and remained
continuously effective (except as otherwise permitted under this Agreement) for
a period ending on the earlier of (i) the date that is nine (9) months after the
effective date of such Registration Statement (subject to extension as provided
in the final paragraph of Section 5(a), Section 6(a) and Section 6(b)) and (ii)
the date on which all Registrable Securities covered by such Registration
Statement have been sold and the distribution contemplated thereby has been
completed; provided, however, that if, after such Registration Statement has
become effective, the offering of the Registrable Securities pursuant to such
registration is interfered with by any stop order, injunction or similar order
of the SEC or other governmental agency or court (other than by reason of any
untrue statement of a material fact or any omission of a material fact required
to be stated in the Registration Statement or necessary to make the statements
therein not misleading, to the extent, but only to the extent, that such untrue
statement or omission is contained in any information or affidavit furnished in
writing by 



                                      - 5 -

   6
a Holder to the Company specifically for inclusion therein), such registration
will be deemed not to have been effected.

                  (c) Inclusion of Securities of Other Approved Holders. The
Company and any Other Approved Holder may include its securities in any demand
registration effected pursuant to this Section 3 that is not a Shelf
Registration; provided, however, that if the managing underwriter or
underwriters of the proposed public offering advises the Holder or Holders
intending to participate in such proposed public offering in writing that the
total amount or kind of securities which such Holders, the Company and such
Other Approved Holders intend to include in such proposed public offering is
sufficiently large to materially adversely affect the success of the proposed
public offering requested by such Holder or Holders, then the amount or kind of
securities to be offered for the accounts of the Other Approved Holders shall be
reduced pro rata among such Other Approved Holders to the extent necessary to
reduce the total amount or kind of securities to be included in such proposed
public offering to the amount or kind recommended by such managing underwriter
or underwriters and, if such reduction results in no securities being offered
for the accounts of the Other Approved Holders in such proposed public offering,
then the amount or kind of securities to be offered for the account of the
Company shall be reduced to the extent necessary to reduce the total amount or
kind of securities to be included in such proposed public offering to the amount
or kind recommended by such managing underwriter or underwriters.

                  SECTION 4. PIGGYBACK REGISTRATION. If the Company at any time
proposes to file a registration statement with respect to any class of equity
securities, whether for its own account (other than in connection with the
Registration Statement contemplated by Section 3 or a registration statement on
Form S-4 or S-8 (or any successor or substantially similar form), or the
registration of (A) an employee stock option, stock purchase or compensation
plan or of securities issued or issuable pursuant to any such plan or (B) a
dividend reinvestment plan) or for the account of an Other Approved Holder (a
"Requesting Securityholder"), then the Company shall in each case give written
notice of such proposed filing to all Holders of Registrable Securities at least
20 days before the anticipated filing date of any such registration statement by
the Company, and such notice shall offer to all Holders the opportunity to have
any or all of the Registrable Securities held by such Holders included in such
registration statement. Each Holder of Registrable Securities desiring to have
its Registrable Securities registered under this Section 4 shall so advise the
Company in writing within 15 days after the date of receipt of such notice
(which request shall set forth the amount of Registrable Securities for which
registration is requested), and the Company shall include in such Registration
Statement all such Registrable Securities so requested to be included therein on
the same terms and conditions as the securities being registered by the Company.
Any Holder's request for such inclusion may be withdrawn, in whole or in part,
at any time prior to the effective date of such Registration Statement.
Notwithstanding the foregoing, if the managing underwriter or underwriters of
any such proposed public offering advises the Company in writing that the total
amount or kind of securities which the Holders of Registrable Securities, the
Company and the Other Approved Holders intend to be included in such proposed
public offering is sufficiently large to materially adversely affect the success
of such proposed public offering, then the amount or kind of securities to be
offered for 


                                      - 6 -
   7
the accounts of Holders of Registrable Securities and the Other
Approved Holders shall be reduced pro rata to the extent necessary to reduce the
total amount or kind of securities to be included in such proposed public
offering to the amount or kind recommended by such managing underwriter or
underwriters before the securities offered by the Company or any Requesting
Securityholder are so reduced.



                  SECTION 5.  REGISTRATION PROCEDURES.

                  (a)      General.  In connection with the Company's 
registration obligations pursuant to Sections 3 and 4 hereof, the Company will,
as expeditiously as practicable:

                           (i) prepare and file with the SEC a new Registration
         Statement or such amendments and post-effective amendments to an
         existing Registration Statement as may be necessary to keep such
         Registration Statement effective for the time periods set forth in
         Section 3(b), provided that no Registration Statement shall be required
         to remain in effect after all Registrable Securities covered by such
         Registration Statement have been sold and distributed as contemplated
         by such Registration Statement, and provided, further, that as soon as
         practicable, but in no event later than three (3) Business Days before
         filing such Registration Statement, any related Prospectus or any
         amendment or supplement thereto, other than any amendment or supplement
         made solely as a result of incorporation by reference of documents
         filed with the SEC subsequent to the filing of such Registration
         Statement, the Company shall furnish to the Holders of the Registrable
         Securities covered by such Registration Statement and the underwriters,
         if any, copies of all such documents proposed to be filed, which
         documents shall be subject to the review of such Holders and
         underwriters; the Company shall not file any Registration Statement or
         amendment thereto or any Prospectus or any supplement thereto (other
         than any amendment or supplement made solely as a result of
         incorporation by reference of documents filed with the SEC subsequent
         to the filing of such Registration Statement) to which the managing
         underwriters of the applicable offering, if any, or the Securityholder
         (if it is participating in such offering) or the Holders of a majority
         of the Registrable Securities (on a Common Stock equivalent basis)
         covered by such Registration Statement shall have reasonably objected
         in writing within three (3) Business Days after receipt of such
         documents to the effect that such Registration Statement or amendment
         thereto or Prospectus or supplement thereto does not comply in all
         material respects with the requirements of the Securities Act (provided
         that the foregoing shall not limit the right of any Holder whose
         Registrable Securities are covered by a Registration Statement to
         reasonably object, within two (2) Business Days after receipt of such
         documents, to any particular information that is to be contained in
         such Registration Statement, amendment, Prospectus or supplement that
         relates specifically to such Holder, including any information
         describing the manner in which such Holder acquired such Registrable
         Securities and the intended method or methods of distribution of such
         Registrable Securities), and if the Company is unable to file any such
         document due to the objections of such underwriters, the Securityholder
         or such Holders, the Company shall use its best efforts to cooperate
         with such underwriters, the Securityholder and Holders to prepare, as
         soon as practicable, a document that is responsive in all material
         respects to the 



                                      - 7 -
   8
         reasonable objections of such underwriters, the Securityholder and
         Holders; cause the Prospectus to be supplemented by any required
         Prospectus supplement, and as so supplemented to be filed pursuant to
         Rule 424; and comply with the provisions of the Securities Act
         applicable to the Company with respect to the disposition of all
         securities covered by such Registration Statement during the applicable
         period in accordance with the intended method or methods of
         distribution by the sellers thereof set forth in such Registration
         Statement, Prospectus or supplement to the Prospectus (it being
         understood that the Company shall not be deemed to have used its best
         efforts to keep a Registration Statement effective during the
         applicable period if any action is taken by the Company that would
         result in Holders of the Registrable Securities covered thereby not
         being able to sell such Registrable Securities during that period
         unless such action is required under applicable law or is contemplated
         under the last paragraph of Section 5(a), Section 6(a) or Section
         6(b));

                           (ii) notify the selling Holders of Registrable
         Securities and the managing underwriters, if any, promptly (providing
         confirmation in writing) (1) when a new Registration Statement,
         Prospectus or any Prospectus supplement or post-effective amendment has
         been filed, and, with respect to any new Registration Statement or

         incorporated therein by reference untrue or which requires the making
         of any changes in any Registration Statement, Prospectus or any

         registration or qualification (or exemption therefrom) effective during
         the period during which such registration statement is required to be
         kept effective pursuant to this Agreement; and do any and all other
         acts or things reasonably necessary or advisable to enable the
         disposition in such jurisdictions of the Registrable Securities covered

                           (ix)     upon the occurrence of any event 
         contemplated by clause (7) of paragraph (ii) above, promptly prepare a
         supplement or post-effective amendment to the Registration Statement or
         the related Prospectus or any document incorporated therein by
         reference or file any other required document so that, as thereafter
         delivered to the purchasers of the Registrable Securities being sold
         thereunder, the Prospectus will not contain an untrue statement of a
         material fact or omit to state any material fact necessary to make the
         statements therein, in the light of the circumstances in which they
         were made, not misleading; if any event described in clause (2) of
         paragraph (ii) above occurs, use its best efforts to cooperate with the
         SEC to prepare, as soon as practicable, any amendment or supplement to
         such Registration Statement or such related Prospectus and any other
         additional information, or to take other action that may have been
         requested by the SEC;

                           (x) cause all Registrable Securities covered by the
         Registration Statement to be listed on each securities exchange (or
         quotation system operated by a national securities association) on
         which identical securities issued by the Company are then listed (or
         included) if requested by the Securityholder (if it is participating in
         such offering) or the Holders of a majority of the Registrable
         Securities (on a Common Stock equivalent basis) covered by such
         Registration Statement or the managing underwriters, if any, and enter
         into customary agreements including, if necessary, a listing
         application and indemnification agreement in customary form, and
         provide a transfer agent for such Registrable Securities no later than
         the effective date of such Registration Statement;

                           (xi) enter into customary agreements (including in
         the case of an Underwritten Offering, an underwriting agreement in
         customary form for the managing underwriters with respect to issuers of
         similar market capitalization and reporting and financial histories)
         and take all such other actions in connection therewith in order to
         expedite or facilitate the disposition of such Registrable Securities
         included in such Registration Statement, in each case, in connection
         with an Underwritten Offering, as the underwriters determine is
         reasonable and customary, and in connection therewith, (1) make such
         representations and warranties to the Holders of such Registrable

         underwritten offerings; (2) obtain opinions of counsel to the Company
         addressed to each selling Holder of such Registrable Securities and to

                                     - 10 -
   11
         substance) shall be reasonably satisfactory to the underwriters and the
         selling Holders of such Registrable Securities and shall cover the

         underwritten offerings and such other matters as may be reasonably
         requested by such Holders and underwriters); (3) obtain "cold comfort"
         letters and updates thereof from the independent certified public
         accountants of the Company addressed to each selling Holder of such

         in customary form and covering matters of the type customarily covered
         in "cold comfort" letters in connection with secondary underwritten
         offerings; (4) the underwriting agreement shall contain indemnification
         and contribution provisions and procedures no less favorable than those
         set forth in Section 8 hereof with respect to all parties to be
         indemnified pursuant to Section 8; and (5) the Company shall deliver
         such documents and certificates as may be reasonably requested by the

                           (xii)  provide a CUSIP number for the Registrable 
         Securities no later than the effective date of such registration
         statement;

                           (xiii) in the case of any nonunderwritten offering:
         (1) obtain opinions of counsel to the Company at the time of
         effectiveness of such Registration Statement covering such offering and
         updates thereof of customary frequency, addressed to each Holder of any
         Registrable Securities participating in such offering and covering
         matters that are no more extensive in scope than would be customarily
         covered in opinions obtained in secondary underwritten offerings by
         issuers with similar market capitalization and reporting and financial
         histories; (2) obtain "cold comfort" letters from the independent
         certified public accountants of the Company at the time of

         Holders of a majority of the Registrable Securities (on a Common Stock
         equivalent basis) covered by such Registration Statement, updates
         thereof of customary frequency, in each case addressed to each Holder

         officer's certificates delivered in connection with underwritten
         offerings by issuers with similar market capitalization and reporting
         and financial histories;



                                     - 11 -
   12
                           (xiv) otherwise use its best efforts to comply with
         all applicable rules and regulations of the SEC relating to such
         registration and the distribution of the securities being offered and
         make generally available to its securities holders earnings statements
         satisfying the provisions of Section 11(a) of the Securities Act, no
         later than 60 days after the end of any 12-month period (or 120 days,
         if such period is a fiscal year) commencing at the end of any fiscal
         quarter in which the Registrable Securities are sold to underwriters in
         a firm commitment or best efforts underwritten offering, or, if not
         sold to underwriters in such an offering, beginning with the first
         month of the Company's first fiscal quarter commencing after the
         effective date of such Registration Statement, which earnings
         statements shall cover such 12-month periods;

                           (xv)     cooperate and assist in any filings 
         required to be made with the National Association of Securities
         Dealers, Inc. and in the performance of any customary or required due
         diligence investigation;

                           (xvi) make available for inspection by the Holders of
         the Registrable Securities covered by such Registration Statement, any
         underwriter participating in any disposition pursuant to such
         registration, and any attorney, accountant or other representative
         retained by such sellers or underwriter, all financial and other
         records, pertinent corporate documents and properties of the Company
         and cause the Company's officers, directors and employees to supply all
         information reasonably requested by, and to cooperate fully with, any
         such representative, underwriter, attorney or accountant in connection
         with such registration;

                           (xvii) subject to the proviso in paragraph (vii)
         above, cause the Registrable Securities covered by the Registration
         Statement to be registered with or approved by such other governmental
         agencies or authorities as may be reasonably necessary to enable the
         seller or sellers thereof or the underwriters, if any, to consummate
         the disposition of such Registrable Securities; and

                           (xviii) use its best efforts to take all action
         necessary or advisable to effect such registration in the manner
         contemplated by this Agreement.

                  The Company may require each seller of Registrable Securities
as to which any registration is being effected to furnish to the Company such
information regarding such seller and the distribution of such securities as the
Company may from time to time reasonably request in writing.

                  Each Holder of Registrable Securities agrees by acquisition of
such Registrable Securities that, upon receipt of any notice from the Company of
the happening of any event of the kind described in Section 5(a)(ii) hereof,
such Holder will forthwith discontinue disposition of Registrable Securities
(but, in the case of an event described in Section 5(a)(ii)(6), in the affected
jurisdiction or jurisdictions only) pursuant to the then current Prospectus
until (1) such Holder is advised in writing by the Company that a new
Registration Statement covering the offer of 


                                     - 12 -
   13
Registrable Securities has become effective under the Securities Act or (2) such
Holder receives copies of a supplemented or amended Prospectus contemplated by
this Section 5(a), or until such Holder is advised in writing by the Company
that the use of the Prospectus may be resumed. If the Company shall have given
any such notice during a period when a demand registration is in effect, the
Company shall extend the period during which such registration statement shall
be maintained effective pursuant to this Agreement by the number of days during
which any such disposition of Registrable Securities is discontinued pursuant to
this paragraph. The Company shall use its best efforts to limit the duration of
any discontinuance with respect to the disposition of Registrable Securities
pursuant to this paragraph.

                  (b) Additional Procedures for Shelf Registration. If the
Holders become entitled, pursuant to an event described in clause (ii) of the
definition of Registrable Securities, to receive any securities in respect of
Registrable Securities that were already included in a Shelf Registration
Statement, subsequent to the date such Shelf Registration Statement is declared
effective, and the Company is unable under the securities laws to add such
securities to the then-effective Shelf Registration Statement, the Company, as
promptly as practicable, shall file, in accordance with the procedures more
particularly set forth in Section 5(a), an additional Shelf Registration
Statement with respect to any such new Registrable Securities. The Company shall
use its best efforts to have any such additional Registration Statement declared
effective as promptly as practicable after such filing and to keep such
additional Shelf Registration Statement continuously effective during the period
specified in Section 3(b). A request to file an additional Shelf Registration
Statement pursuant to this paragraph shall not constitute a demand under Section
3(a).

                  SECTION 6.  HOLDBACK AGREEMENTS.

                  (a) Hold-Back Election. Subject to Section 6(c), in the case
of the registration of any underwritten primary offering initiated by the
Company (other than any registration by the Company on Form S-4 or Form S-8 (or
any successor or substantially similar form), or the registration of (A) an
employee stock option, stock purchase or compensation plan or of securities
issued or issuable pursuant to any such plan or (B) a dividend reinvestment
plan) or any underwritten secondary offering initiated at the request of an
Other Approved Holder, each Holder agrees, if and to the extent requested in
writing by the managing underwriter or underwriters administering such offering
as promptly as reasonably practicable prior to the commencement of the 10-day
period referred to below (a "Hold-Back Election"), not to effect any public sale
or distribution of securities of the Company except as part of such underwritten
registration, during the period beginning 10 days prior to the effective date of
the applicable registration statement relating to such underwritten offering and
ending on the earlier of (i) 90 days after such effective date and (ii) the date
such sale or distribution is permitted by such managing underwriter or
underwriters. In the event such managing underwriter or underwriters shall
exercise a Hold-Back Election during a period when a Registration Statement
filed pursuant to Section 3 is in effect, the time period specified in Section
3(b) during which such Registration Statement is required to be kept effective
shall be extended by the number of days during which the Holders are prohibited
by such underwriter or underwriters from publicly selling or distributing their
securities. 



                                     - 13 -
   14
Notwithstanding the foregoing provisions of this Section 6(a), no
Holder shall be obligated to refrain from making any public sale or distribution
of securities of the Company in the case of any underwritten secondary offering
initiated at the request of any Person who has not agreed in writing to
expressly recognize and give effect to the Holders' rights under this Section
6(a), and to be subject to provisions that are at least as favorable to the
Holders as the provisions contained in this Section 6(a) are to such holder.

                  (b) Material Development Election. Subject to Section 6(c),
the Company shall be entitled, for a period of time not to exceed 90 consecutive
days, to postpone the filing of any Registration Statement otherwise required to
be prepared and filed by it pursuant to Section 3 and/or to request that the
Holders refrain from effecting any public sales or distributions of their
Registrable Securities if the board of directors of the Company in good faith
determines in its reasonable business judgment that such registration and/or
such public sales or distributions would interfere in any material respect with
any financing (other than an underwritten secondary offering of any securities
of the Company), acquisition, corporate reorganization or other transaction or
development involving the Company or any subsidiary of the Company that in the
reasonable good faith business judgment of such board is a transaction or
development that is or would be material to the Company (a "Material Development
Election"). The board of directors of the Company shall, as promptly as
practicable, give the Holders written notice of any such Material Development
Election. In the event of a determination by the board of directors to postpone
the filing of a Registration Statement required to be filed under Section 3
hereof, the Company shall be required to file such Registration Statement as
soon as practicable after the board of directors of the Company shall determine,
in its reasonable business judgment, that the filing of such Registration
Statement and the offering thereunder shall not interfere with the aforesaid
material transaction or development, but in any event no later than the end of
such 90-day period. In addition, if the board of directors of the Company has
requested that the Holders refrain from making public sales or distributions of
their Registrable Securities, such board shall, as promptly as practicable
following its determination that the Holders may recommence such public sales
and distributions, notify such Holders in writing of such determination (but in
any event no later than the end of such 90-day period). In the event the Company
shall exercise a Material Development Election during a period when a
Registration Statement filed pursuant to Section 3 is in effect, the time period
specified in Section 3(b) during which such Registration Statement is required
to be kept effective shall be extended by the number of days during which the
Holders are prohibited by the Company from publicly selling or distributing
their securities.

                  (c) Hold-Back Limitation. In no event shall the restrictions
under Section 6(a) or Section 6(b), pursuant to one or more Hold-Back Elections
or Material Development Elections, remain in effect for more than 90 days in the
aggregate in any calendar year.

                  (d) Company Hold-Back. In the case of each underwritten
offering of Registrable Securities pursuant to Section 3, including under any
Shelf Registration Statement, the Company agrees, if and to the extent requested
in writing by the managing underwriter or underwriters administering such
offering as promptly as reasonably practicable prior to the commencement of the
10-day period referred to below, not to effect any public sale or distribution



                                     - 14 -
   15
(other than sales pursuant to the same Registration Statement, as permitted
under this Agreement, or any registration by the Company on Form S-4 or S-8 (or
any successor or substantially similar form) or the registration of (A) an
employee stock option, stock purchase or compensation plan or of securities
issued or issuable pursuant to any such plan or (B) a dividend reinvestment
plan) of any securities of the Company during the period beginning 10 days prior
to the effective date of the applicable registration statement relating to such
underwritten offering of Registrable Securities and ending on the earlier of (i)
90 days after such effective date and (ii) the date such sale or distribution is
permitted by such managing underwriter or underwriters. Any agreement entered
into after the date of this Agreement pursuant to which the Company issues or
agrees to issue any privately placed securities similar to any issue of the
Registrable Securities shall contain a provision under which holders of such
securities agree not to effect any public sale or distribution of any such
securities during the period described in the next preceding sentence.

                  SECTION 7. REGISTRATION EXPENSES. All expenses incident to the
Company's performance of or compliance with this Agreement, including all
registration and filing fees, fees and expenses of compliance with securities or
blue sky laws (including reasonable fees and disbursements of counsel in
connection with blue sky qualifications or registrations (or the obtaining of
exemptions therefrom) of the Registrable Securities), printing expenses

employees performing legal or accounting duties), fees and disbursements of its
counsel and its independent certified public accountants (including the expenses

Common Stock equivalent basis) being sold pursuant to such registration,
incurred in connection with each registration hereunder, and reasonable
out-of-pocket expenses incurred by the Holders (except as set forth in the
proviso hereafter) (all such expenses being referred to as "Registration
Expenses"), shall be borne by the Company, whether or not any registration
statement becomes effective (subject, however, to the provisions of Section
3(a)); provided that Registration Expenses shall not include any underwriting
discounts, commissions or fees attributable to the sale of the Registrable
Securities.

                  SECTION 8.  INDEMNIFICATION; CONTRIBUTION.

                  (a) Indemnification by the Company. The Company shall
indemnify and hold harmless, to the full extent permitted by law, but without
duplication, each Holder of Registrable Securities, its officers, directors,
employees, partners, principals, equity holders, managed or advised accounts,
advisors, representatives and agents, and each Person who controls such Holder
or such other Persons (within the meaning of the Securities Act) and any
investment advisor thereof or agent therefor, against all losses, claims,
damages, liabilities and expenses (including reasonable costs of investigation
and reasonable legal fees and expenses) arising out of or based 



                                     - 15 -
   16
upon any untrue or alleged untrue statement of a material fact in, or any
omission or alleged omission of a material fact required to be stated in, any
Registration Statement or any Prospectus, or necessary to make the statements
therein (in the case of a Prospectus, in light of the circumstances under which
they were made) not misleading, except in each case insofar, but only insofar,
as the same arises out of or is based upon an untrue statement or alleged untrue
statement of a material fact or an omission or alleged omission to state a
material fact in such Registration Statement or Prospectus, as the case may be,
made or omitted, as the case may be, in reliance upon and in conformity with
written information furnished to the Company by such Holder expressly for use
therein. The Company shall also indemnify underwriters of the Registrable
Securities, selling brokers, dealer managers and similar securities industries
professionals participating in the distribution, and their officers, directors,
employees, partners, principals, equity holders, advisors, representatives and
agents, and each Person who controls such underwriters or other Persons (within
the meaning of the Securities Act), to the same extent as provided above with
respect to the indemnification of the Holders of Registrable Securities and
other specified Persons. This indemnity is in addition to any liability that the
Company may otherwise have.

                  (b) Indemnification by Holders of Registrable Securities. In
connection with any Registration Statement in which a Holder of Registrable
Securities is participating, each such Holder shall furnish to the Company in
writing such information and affidavits with respect to such Holder as the
Company reasonably requests for use in connection with such Registration
Statement or any Prospectus, and shall indemnify and hold harmless, to the full
extent permitted by law, but without duplication, the Company, its officers,
directors, shareholders, employees, advisors, representatives and agents, and
each Person who controls the Company or such other Persons (within the meaning
of the Securities Act) and any investment advisor thereof or agent therefor,
against any losses, claims, damages, liabilities and expenses (including
reasonable costs of investigation and reasonable legal fees and expenses)
arising out of or based upon any untrue or alleged untrue statement of a
material fact in, or any omission or alleged omission of a material fact
required to be stated in, the Registration Statement or any Prospectus, or
necessary to make the statements therein (in the case of a Prospectus, in light
of the circumstances under which they were made) not misleading, in each case to
the extent, but only to the extent, that the same arises out of or is based upon
an untrue statement or alleged untrue statement of a material fact or an
omission or alleged omission to state a material fact in such Registration
Statement or Prospectus, as the case may be, made or omitted, as the case may
be, in reliance upon and in conformity with written information furnished to the
Company by such Holder expressly for use therein. The Company shall be entitled
to receive indemnities from underwriters, selling brokers, dealer managers and
similar securities industries professionals participating in the distribution,
to the same extent as provided above with respect to information so furnished in
writing by such Persons specifically for inclusion in any Prospectus or
Registration Statement. Notwithstanding any other provision hereof to the
contrary, in no event shall the liability of any selling Holder of Registrable
Securities hereunder be greater in amount than the dollar amount of the net
proceeds actually received by such Holder upon the sale of the Registrable
Securities giving rise to such indemnification obligation.

   17
                  (c) Conduct of Indemnification Proceedings. Any Person
entitled to indemnification under this Section 8 will (i) give prompt written
notice to the indemnifying party of any claim with respect to which it seeks
indemnification and (ii) permit such indemnifying party to assume the defense of
such claim with counsel reasonably satisfactory to the indemnified party;
provided, however, that any Person entitled to indemnification hereunder shall
have the right to employ separate counsel and to participate in the defense of
such claim, but the fees and expenses of such counsel shall be at the expense of
such indemnified Person unless (A) the indemnifying party has agreed to pay such
fees or expenses, (B) the indemnifying party shall have failed to assume the
defense of such claim and employ counsel reasonably satisfactory to the
indemnified party in a timely manner or (C) in the reasonable judgment of any
such Person, based upon advice of its counsel, a conflict of interest may exist
between such Person and the indemnifying party with respect to such claims (in
which case, if the Person notifies the indemnifying party in writing that such
Person elects to employ separate counsel at the expense of the indemnifying
party, the indemnifying party shall not have the right to assume the defense of
such claim on behalf of such Person). The indemnifying party will not be subject
to any liability for any settlement made without its consent (but such consent
will not be unreasonably withheld or delayed). No indemnified party will be
required to consent to entry of any judgment or enter into any settlement which
does not include as an unconditional term thereof the giving by the claimant or
plaintiff to such indemnified party of a release from all liability in respect
of such claim or litigation. An indemnifying party who is not entitled to, or
elects not to, assume the defense of a claim will not be obligated to pay the
fees and expenses of more than one counsel for all parties indemnified by such
indemnifying party with respect to such claim, as well as one local counsel in
each relevant jurisdiction.

                  (d) Contribution. If for any reason the indemnification
provided for in Section 8(a) or Section 8(b) is unavailable to an indemnified
party, then the indemnifying party, in lieu of indemnifying such indemnified
party, shall contribute to the amount paid or payable by the indemnified party
as a result of such loss, claim, damage, liability or expense in such proportion
as is appropriate to reflect not only the relative benefits received by the
indemnifying party and the indemnified party, but also the relative fault of the
indemnifying party and the indemnified party in connection with the actions that
resulted in such loss, claim, damage, liability or expense, as well as any other
relevant equitable considerations, provided that no indemnifying Holder shall be
required to contribute an amount greater than the dollar amount of the net
proceeds actually received by such indemnifying Holder with respect to the sale
of the Registrable Securities giving rise to such contribution obligation. The
relative fault of such indemnifying party and indemnified party shall be
determined by reference to, among other things, whether any action in question,
including any untrue or alleged untrue statement of a material fact or omission
or alleged omission to state a material fact, has been made by, or relates to
information supplied by, such indemnifying party or indemnified party, and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such action. The amount paid or payable by a party as a
result of the losses, claims, damages, liabilities and expenses referred to
above shall be deemed to include, subject to the limitations set forth herein,
any legal or other fees or expenses reasonably incurred by such party in
connection with any investigation or proceeding. The parties hereto agree that
it would not be just and equitable if contribution pursuant to this 


                                     - 17 -
   18
Section 8(d) were determined by pro rata allocation or by any other method of
allocation that does not take account of the equitable considerations referred
to in this paragraph. No Person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any Person who was not guilty of such fraudulent
misrepresentations.

                  SECTION 9. RULES 144 AND 144A. The Company shall use its best
efforts to make publicly available and available to the Holders, pursuant to
Rule 144, such information as is necessary to enable the Holders to make sales
of Registrable Securities pursuant to that Rule. The Company shall use its best
efforts to file timely with the SEC all documents and reports required of the
Company under the Exchange Act. The Company shall furnish to any Holder, upon
request, a written statement executed on behalf of the Company as to compliance
with the current public information requirements of Rule 144. In addition, the
Company will provide to any Holder of a Registrable Security, or any potential
purchaser of a Registrable Security, upon any such Person's reasonable request,
the information required by paragraph (d)(4) of Rule 144A.

                  SECTION 10.  PARTICIPATION IN UNDERWRITTEN REGISTRATIONS.

                  (a) If any of the Registrable Securities covered by a demand
registration hereunder are to be sold in an Underwritten Offering, the
investment banker or investment bankers and manager or managers that will
administer the offering will be selected by the Securityholder (if it is
participating in such offering) or, if such Securityholder is not so
participating in such offering, the Holders of a majority of the Registrable
Securities (on a Common Stock equivalent basis) included in such offering;
provided that such investment bankers and managers must be reasonably
satisfactory to the Company, acting in good faith.

                  (b) No Person may participate in any Underwritten Offering
hereunder unless such Person (i) agrees to sell such Person's Registrable
Securities on the basis provided in any underwriting arrangements approved by
the Persons entitled hereunder to approve such arrangements and (ii) completes
and executes all questionnaires, powers of attorney, indemnities, underwriting
agreements and other documents required under the terms of such underwriting
arrangements. Nothing in this Section 10 shall be construed to create any
additional rights regarding the registration of Registrable Securities in any
Person otherwise than as set forth herein.

                  SECTION 11. NO INCONSISTENT AGREEMENTS. The Company (i) except
as set forth on Schedule 11 attached hereto, has not previously entered into any
agreement or understanding that is still in effect on the date hereof pursuant
to which it has granted registration or similar rights to any Person who holds
any of its securities and (ii) shall not enter into any agreement or
understanding (x) with respect to registration or similar rights on any of its
securities with any Person other than an Other Approved Holder or (y) which is
inconsistent with the rights granted to the Holders in this Agreement or
otherwise conflicts with the provisions hereof.

                  SECTION 12. AMENDMENTS AND WAIVERS. The provisions of this
Agreement, including the provisions of this Section 12, may not be amended,
modified or supplemented, and waivers or consents to departures from the
provisions hereof may not be given unless the Company has obtained the written
consent of the Securityholder (if the Securityholder then holds any Registrable
Securities) and the Holders of a majority of the Registrable Securities (on a
Common Stock equivalent basis) then outstanding. Whenever the consent or
approval of Holders of a specified number of Registrable Securities is required
hereunder, Registrable Securities held by the Company or any of its Affiliates
(other than Holders of Registrable Securities if such subsequent Holders are
deemed to be Affiliates solely by reason of their holdings of such Registrable
Securities) shall not be counted in determining whether such consent or approval
was given by the Holders of such required number.

                  SECTION 13. REMEDIES. Each Holder having rights under any
provision of this Agreement shall be entitled to enforce such rights
specifically or to recover damages or to exercise any other remedy available to
it at law or in equity. The foregoing rights and remedies shall be cumulative
and the exercise of any right or remedy provided herein shall not preclude any
Person from exercising any other right or remedy provided herein. The Company
agrees that monetary damages would not be adequate compensation for any loss
incurred by reason of a breach by it of any of the provisions of this Agreement
and hereby agrees to waive the defense in any action for specific performance
that a remedy at law would be adequate.

                  SECTION 14. NOTICES. All notices and other communications
provided for or permitted hereunder shall be made in writing by hand delivery,
registered first-class mail, telecopier or air-courier guaranteeing overnight

                           (a) If to a Holder of Registrable Securities, at the

         with the provisions of this Section 14, which address initially is,

                           (c) All such notices and other communications shall
         be deemed to have been delivered and received (i) in the case of
         personal delivery, telecopier or telegram, on the date of such
         delivery, (ii) in the case of air courier, on the Business Day after
         the date 


                                     - 19 -

         when sent and (iii) in the case of mailing, on the third Business Day
         following such mailing.

                  SECTION 15. SUCCESSORS AND ASSIGNS. This Agreement shall inure
to the benefit of and be binding upon the successors and assigns of each of the
parties hereto, including and without the need for an express assignment to
subsequent Holders of the Registrable Securities who cannot freely transfer
their shares in the absence of registration under the Securities Act.

                  SECTION 16. COUNTERPARTS. This Agreement may be executed in
any number of counterparts and by the parties hereto in separate counterparts,
each of which when so executed shall be deemed to be an original and all of
which taken together shall constitute one and the same agreement.

                  SECTION 17. HEADINGS. The headings in this Agreement are for
convenience of reference only and shall not limit or otherwise affect the
meaning hereof. The use of the word "including" herein shall be interpreted to
mean "including, without limitation," unless the context clearly requires
another interpretation.

                  SECTION 18. GOVERNING LAW. This Agreement shall be deemed to
be a contract made under and shall be governed by and construed in accordance
with the internal laws of the State of New York without reference to the
principles of conflict of laws.

                  SECTION 19. JURISDICTION; FORUM. Each party hereto consents
and submits to the jurisdiction of any state court sitting in the County of New
York or federal court sitting in the Southern District of the State of New York
in connection with any dispute arising out of or relating to this Agreement.
Each party hereto waives any objection to the laying of venue in such courts and
any claim that any such action has been brought in an inconvenient forum. To the
extent permitted by law, any judgment in respect of a dispute arising out of or
relating to this Agreement may be enforced in any other jurisdiction within or
outside the United States by suit on the judgment, a certified copy of such
judgment being conclusive evidence of the fact and amount of such judgment. Each
party hereto agrees that personal service of process may be effected by any of
the means specified in Section 14, addressed to such party. The foregoing shall
not limit the rights of any party to serve process in any other manner permitted
by law.

                  SECTION 20. SEVERABILITY. In the event that any one or more of
the provisions contained herein, or the application thereof in any circumstance,
is held invalid, illegal or unenforceable, the validity, legality and
enforceability of any such provision in every other respect and of the remaining
provisions contained herein shall not be affected or impaired thereby.

                  SECTION 21. ENTIRE AGREEMENT. This Agreement is intended by
the parties as a final expression of their agreement and is intended to be a
complete and exclusive statement of the agreement and understanding of the
parties hereto in respect of the subject matter contained herein. This Agreement
supersedes all prior agreements and understandings between the parties with
respect to such subject matter, whether written or oral.
