                  (b) In the event that Buyers shall reasonably establish to the
Sellers' reasonable satisfaction and notify Sellers at any time or from time to
time during the three-month period following the Closing Date that any of the
Schedules describing the Assets as provided in Section 1.01(a) hereof failed to
include assets or properties of Global or Management used by Global or
Management exclusively or primarily in the Business (other than any such assets
or properties specifically excluded under Section 1.01(c) hereof or made

         used exclusively in the Business, Sellers shall promptly convey,
         transfer, assign and deliver to Buyers or other such person as may be
         designated by Buyers, and Buyers or such designee shall acquire from
         Sellers, without additional consideration, all such assets and
         properties, which shall be deemed for all purposes to be included in
         the definition of Assets hereunder as provided in Section 1.01(a)
         hereof.

                           (ii) with respect to any such assets or properties
         used primarily, but not exclusively, in the Business, Sellers shall
         grant to Buyers an irrevocable, royalty-free license or otherwise
         convey to Buyers the unlimited right to use any such asset or property,
         without additional consideration.

                  (c) Anything herein contained to the contrary notwithstanding,
the following assets and properties of Global and Management are specifically
excluded from the Assets and shall be retained by Global and Management:

                           (i) all cash in banks, cash on hand and short-term
         investments as of the Closing Date;

                           (ii) except as set forth on Schedule 1.01(a)(viii)
         hereto, all accounts receivable of Seller attributable to the Business
         through the Closing Date;

                           (iii) all claims or rights against third parties
         relating to liabilities or obligations (including, without limitation,
         any such liabilities or obligations referred to in clause (ii) of
         Section 2.04) that are not assumed by Buyer hereunder;

                           (iv) all claims for the refund of Taxes (as
         hereinafter defined) and other governmental charges of whatever nature
         for all periods prior to the close of business on the day prior to the
         Closing Date;

                           (v) all rights and funds in connection with
         retirement and profit sharing plans;

                           (vi) the minute books, stock records and related
         corporate records of Global and Management; and

                           (vii) those items listed on Schedule 1.01(c)(vii)
         hereto.

                  (d) Each of the Buyers, on the one hand, and Sellers, on the
other hand, agrees to cooperate with the other parties hereto to establish
reasonable procedures to identify and remit payments received but not owned by
them from third parties, being amounts attributable to Global's and Management's
conduct of the Business prior to the Closing Date or Buyers' conduct of the
Business after the Closing Date, as the case may be, which amounts shall, for
the purposes of this Section 1.01(d), include payments under the Subcontracted
Contracts (as defined in Section


                                       4
   10

1.03 hereof). Such payments shall be made promptly, but in no event later than
15 days after receipt thereof by Buyers or Sellers, as the case may be. The
parties agree to reasonably cooperate with the other parties hereto and use
their reasonable efforts, at the request and expense of the other parties, and
to assist each other, under the direction of the party entitled to such
payments, in the collection of amounts due to such parties.

                  SECTION 1.02 Instruments of Conveyance and Transfer. On the
Closing Date, Sellers shall execute and deliver to Buyers (i) a bill of sale in
the form included in the form of the Bill of Sale, Assignment and Assumption
Agreement annexed hereto as Exhibit A (the "Bill of Sale") and (ii) such other
documents of transfer that Buyers may reasonably request, transferring to Buyers
the properties and assets to be acquired by Buyers under the terms of this
Agreement.

                  SECTION 1.03 Nonassignable Contracts. Nothing in this
Agreement shall be construed as an attempt or agreement to assign (i) any
contract, agreement, license, lease, sales order, purchase order or other
commitment that is nonassignable without the consent of the other party or
parties thereto unless such consent shall have been given, subject, however, to
the covenant of Sellers in Section 4.01(d) hereof, or (ii) any contract or claim
as to which all the remedies for the enforcement thereof enjoyed by Sellers
would not pass to Buyers as an incident of the assignments provided for by this
Agreement. In order, however, that the full value of every contract and claim of
the character described in clauses (i) and (ii) above, and all claims and
demands on such contracts may be realized, Sellers shall use all reasonable
efforts to obtain consent for the assignment thereof, other than any such

Section 4.01(d) hereto and this Section 1.03 listed on Schedule 1.03 hereto,
Sellers shall, at the request and expense and under the direction of Buyers, in
the name of Sellers or otherwise as Buyers shall specify and as shall be
permitted by law, take all action and do or cause to be done all things as shall
in the opinion of Buyers be reasonably necessary or proper (x) in order that the
rights and obligations of Sellers under such contracts shall be preserved and

as the parties may mutually agree in writing, after satisfaction of all of the
conditions set forth in Sections 6.01 and 6.02 hereof, and for all purposes
shall be deemed effective as of the close of business on the day prior to such

45 days after the date of this Agreement.

                  SECTION 2.02 Payment to Sellers on the Closing Date. On the

Buyers shall execute and deliver to Sellers an Assumption Agreement, in the form
included in the Bill of Sale, pursuant to which Buyers shall assume and agree to
pay, perform and discharge when due all liabilities and obligations of Global
and Management that arise on and after the Closing Date under the terms of any
contract, agreement, license, lease, sales order, purchase order or other
commitment that is disclosed on Schedules 3.01(h) (other than any commitment of
the kind described in Section 3.01(h)(iii) hereof) or 3.01(q) hereto, other than
any of the foregoing that shall not be assigned as contemplated by Section 1.03
hereof; provided, however, that if at any time after

thereunder. On the Closing Date, Buyers shall also assume and agree to be
responsible for all obligations of Sellers in respect of vacation accrued for
the Retained Employees prior to the Closing Date as set forth on Schedule 2.03;
provided that Buyers may make it a condition to the offers of employment made
pursuant to Section 4.07(a) that any such accrued vacation be utilized within
twelve months of the Closing Date or expire at such time.

                  SECTION 2.04 Non-Assumption of Certain Liabilities. Subject as
set forth in Section 2.05, Buyers are not assuming, and shall not be deemed to
have assumed, any liabilities or obligations of Sellers of any kind or nature
whatsoever, except as expressly provided herein or in the Bill of Sale. Without
limiting the generality of the foregoing, it is hereby agreed that Buyers are
not assuming any liability and shall not have any obligation for or with respect
to: (i) any liabilities or obligations of Sellers that arise under the terms of
a contract, agreement, license, lease, sales order, purchase order, or other
commitment which shall not be assigned as contemplated by Section 1.01(c) of
this Agreement; (ii) any liabilities or obligations of Sellers (x) attributable
to the operations of the Business prior to the Closing Date or (y) that would
not have arisen but for the consummation of the transactions contemplated by
this Agreement, unless, in either case, such liabilities or obligations are
expressly assumed by Buyers as provided herein or in the Bill of Sale; (iii) any
liabilities or obligations of Sellers under any Plan (as defined in Section
3.01(k)), including any obligation to adopt or to sponsor such Plan except as
Buyers may, in their sole discretion, elect to adopt or to sponsor; (iv) any
liabilities or obligations of Sellers for any commissions, refunds, rebates,
discounts or other such sums, falling due before the Closing Date, in respect of
services rendered prior to the Closing Date; (v) any obligation of Sellers
arising out of any action, suit or proceeding based upon (A) an event occurring
or a claim arising prior to the Closing Date or (B) a claim arising on and after
the Closing Date based on an event occurring prior to the Closing Date in the
case of claims in respect of products or services sold and delivered or required
to be delivered by Sellers or provided by Sellers or the conduct of the Business
prior to the Closing Date and attributable to acts performed or omitted by
Sellers prior to the Closing Date; (vi) any obligation of Sellers to any
employee in respect of personal or sick days accrued prior to the Closing Date;

employee of, or consultant to, the Business who does not become a Retained
Employee (as hereinafter defined) or to any other employee of, or consultant to,
the Business whose employment or consultancy is terminated by Sellers prior to
or effective at the Closing Date or, except as provided in Section 4.07 hereof,
to any employee who is on administrative leave as of the Closing Date; and
(viii) any and all Taxes incurred by or imposed upon Sellers relating to periods
prior to the Closing Date, whether such Taxes are assessed before or after the
Closing Date, including without limitation, but subject to the provisions of
Section 4.05(a) hereof, any Taxes incurred by or lawfully imposed upon Sellers,
other than any Taxes to be paid by Buyers in accordance with this Agreement or
any of the Ancillary Agreements.

                  SECTION 2.05 Sellers' Net Funding Requirement. (a) Buyers and
Sellers agree that Sellers shall pay to Buyers on the Closing Date, in cash, an
amount equal to the net amount ("Sellers' Net Funding Requirement") set forth on
Schedule 2.05(a) calculated by subtracting the amounts described in clauses
(iii) and (iv) below from the amount described in clauses (i) and (ii) below;
provided, however, that if the Sellers' Net Funding Requirement is less than
zero, Buyers shall pay to Sellers on the Closing Date, in cash, an amount equal
to such negative amount:



         (i) Unearned Revenues. The aggregate of all payments received prior to
         the Closing Date, in each case, with respect to ongoing liabilities and
         obligations of Sellers to provide products or services after the day
         prior to the Closing Date (including, without limitation, all customer
         advance payments, maintenance fees and the estimated value of all
         warranty obligations to be discharged or performed with respect to work
         performed or services rendered prior to the Closing Date) under any
         contract listed on Schedule 3.01(q) hereto, all of which payments and
         amounts have been identified and set forth by Sellers on Schedule
         2.05(a)(i) hereto;

         (ii) Accrued Expenses. The aggregate of all expenses of the Business
         that relate to any period prior to 12:00 midnight on the day prior to
         the Closing Date in respect of which Sellers have not made payment or,
         subject to payment thereof on or before the due date thereof, an
         account payable has arisen or an accrual made on Sellers' books of
         account prior to the Closing Date for which Sellers will not remain
         responsible after the Closing Date, which amounts have been identified
         and set forth by Sellers on Schedule 2.05(a)(ii) hereto;

                                       8
   14



         (iii) Prepaid Expenses and Security Deposits. The aggregate of (A) all
         expenses of the Business that relate to any period after 12:01 a.m. on
         the Closing Date and for which Buyers will receive the benefit in
         respect of which Sellers have made payment or, subject to payment
         thereof on or before the due date thereof, an account payable has
         arisen or an accrual made on Sellers' books of account prior to the
         Closing Date for which Sellers will remain responsible after the
         Closing Date and (B) all security deposits deposited by Sellers in
         connection with any contract, agreement, license, lease, sales order,
         purchase order or other commitment that is assumed by Buyers pursuant
         to the terms of the Agreement, which amounts have been identified and
         set forth by Sellers on Schedule 2.05(a)(iii) hereto; and

         (iv) Work in Process. Amounts represented by the value, as determined
         in accordance with the related contract in respect thereof, of products
         and services that shall have been supplied by the Sellers prior to the
         Closing Date under any contract listed on Schedule 3.01(q) hereto but
         have not yet given rise to an account receivable of Sellers, payment
         for which will be included in invoices of Buyers and not Sellers after
         the Closing Date, which amounts have been identified and set forth by
         Sellers on Schedule 2.05(a)(iv) hereto.

                  (b) In the event that Buyers or Sellers shall, at any time or
from time to time during the three-month period following the Closing Date,
notify the other in writing, that any of Schedules 2.05(a)(i) through
2.05(a)(iv) failed to include amounts, which properly should reasonably have
been included in such Schedules in accordance with generally accepted accounting
principles, based on the information available to Sellers, after due inquiry, as
of the Closing Date, but not thereafter, then Buyers or Sellers, as the case may
be, shall promptly pay to the other such amount.

                  (c) To the extent that any amounts described in Section
2.05(a)(i) and (ii) hereof has been fully provided for and included in the
amount to be paid in respect of Sellers' Net Funding Requirement, Buyers shall
be deemed upon such payment to have assumed the related liability and
obligation, notwithstanding anything to the contrary contained in Section 2.04
hereof. Conversely, to the extent that any amount described in Section
2.05(a)(iii) and (iv) hereof has been fully provided for and deducted from the
amount to be paid in respect of Sellers'


                                       9
   15

Net Funding Requirement, Buyers shall be deemed upon such payment to have
acquired the related asset (which shall be deemed for all purposes to be
included in the definition of Assets hereunder), notwithstanding anything to the
contrary contained in Section 1.01(c) hereof.

                  SECTION 2.06 Change of Names. At the Closing, Sellers shall
cause the corporate names of Global and Management to be changed to names which
are not confusingly similar to the names of Global and Management, and shall
assign all their rights to Global's and Management's names to Buyers. Sellers
shall furnish to Buyers at the Closing all documents reasonably necessary to
enable Buyers to utilize and/or register such names following the Closing,
including any consents required by the states of California, Delaware, Maryland,
New York and all other jurisdictions where Global and Management are qualified
to do business as foreign corporations. In addition, Sellers will use their best
efforts to obtain the consent of any other person whose consent to Buyers' use
of such names is required, provided, that Sellers shall not be required to pay
any money to obtain such consent. Sellers agree that they will not, subsequent
to the Closing, cause Global and Management to amend their Certificates of
Incorporation to any corporate name which is confusingly similar to Global
Health Systems, Inc. or GHS Management Services, Inc., respectively.

                  III. REPRESENTATIONS AND WARRANTIES

                  SECTION 3.01 Representations and Warranties of Sellers.
Sellers represent and warrant to Buyers as follows:

                  (a) Organization, Corporate Power, Etc. Each of GHS, Global
and Management is a corporation duly organized, validly existing and in good
standing under the laws of the jurisdiction of its incorporation and is duly
qualified to do business as a foreign corporation in each jurisdiction in which
it is required to be so qualified with respect to the operations of the
Business, except where the failure to be so qualified would not have a material
adverse effect on the properties, results of operations, financial condition or
prospects of the Business (a "Material Adverse Effect"). Sellers have all
requisite corporate power and authority to own, operate and lease the Assets, to
carry on the Business as it is now being conducted, to execute and deliver this
Agreement and the Ancillary Agreements and to perform their obligations
hereunder and thereunder. Schedule 3.01(a) hereto sets forth a complete list of
the jurisdictions in which Global and Management are qualified to do business
with respect to the operations of the Business.

                                       10
   16

                  (b) Authorization of Agreements. The execution and delivery by
Sellers of this Agreement and the Ancillary Agreements, and the consummation by
Sellers of the transactions contemplated hereby and thereby, have been duly
authorized by all requisite corporate action, subject to approval of this
Agreement by the stockholders of GHS. This Agreement has been duly and validly
executed by Sellers and, subject to such approval by the stockholders of GHS,
constitutes the legal, valid and binding obligation of Sellers, enforceable in
accordance with its terms and the Ancillary Agreements, when duly executed and
delivered in accordance with this Agreement, will constitute legal, valid and
binding obligations of Sellers, enforceable in accordance with their respective
terms, except as enforceability may be limited by applicable equitable
principles or by bankruptcy, insolvency, reorganization, moratorium, or similar
laws from time to time in effect affecting the enforcement of creditors' rights
generally. All of the issued and outstanding capital stock of Global and
Management is owned by GHS. Except for the requisite affirmative vote of GHS
under the laws of the State of Delaware, the authorization of no other person or
entity is required to consummate the transactions contemplated herein by virtue
of any such person or entity having an equitable or beneficial interest in
Global or Management.

                  (c) Effect of Agreements. Except as set forth on Schedule
3.01(c) hereto, the execution and delivery by Sellers of this Agreement and the
Ancillary Agreements, and the performance by Sellers of their obligations
hereunder and thereunder, will not violate any provision of law, any order of
any court or other agency of government, the Certificates of Incorporation or
By-laws of Sellers, or any judgment, award or decree or any indenture,
agreement, permit or other instrument to which Sellers are parties, or by which
Sellers or any of the Assets are bound or affected, or conflict with, result in
a breach of or constitute (with due notice or lapse of time or both) a default
under, any such indenture, agreement, permit or other instrument, or result in
the creation or imposition of any lien, charge, security interest or encumbrance
of any nature whatsoever upon any of the Assets.

                  (d) Governmental Approvals. Except as set forth on Schedule
3.01(d) hereto, no approval, authorization, consent or order or action of or
filing with any court, administrative agency or other governmental authority (i)
is required for the execution and delivery by Sellers of this Agreement or any
of the Ancillary Agreements or the consummation by Sellers of the transactions
contemplated hereby or thereby or (ii) is necessary in order that the Business
may be conducted immediately following


                                       11
   17

the Closing Date substantially in the same manner as heretofore conducted, other
than those that become applicable solely as a result of the specific regulatory
status of Buyers or its affiliates.

                  (e) Financial Statements. Attached as Schedule 3.01(e) hereto
are the unaudited balance sheet of each of Global and Management as at December
31, 1996 (collectively, the "December Balance Sheets") and the related statement
of operations of each of Global and Management for the nine months ended
December 31, 1996 (collectively with the December Balance Sheets, the "Financial
Statements"). The Financial Statements are complete and correct in all material
respects and have been prepared in accordance with generally accepted accounting
principles (including, without limitation, Global's and Management's policies of
revenue recognition), consistently applied and consistent with prior periods,
except that the Financial Statements will be subject to normal year-end
adjustments, which adjustments in the aggregate will not have a Material Adverse
Effect. Except as set forth on Schedule 3.01(e) hereto, the Financial Statements
fairly present the operating results of the Business during the period indicated
therein.

                  (f) Absence of Certain Changes or Events. Since December 31,
1996, except as otherwise set forth on Schedule 3.01(f) hereto and except for
the transactions contemplated hereby, Sellers have not with respect to the

         ordinary course of business between the date of delivery and payment);

   19

Non-Software Assets. Except as set forth on Schedule 3.01(g) hereto, all leases
of personal property of Sellers to be assigned to Buyers hereunder are, to the
knowledge of Sellers, valid and binding in accordance with their respective
terms and there is not under any of such leases any existing default, or any
condition, event or act attributable to Sellers or, to the knowledge of Sellers,
attributable to the other party to such leases, which with notice or lapse of
time or both would constitute such a default, nor would consummation of the
transactions contemplated hereby result in a default or any such condition,
event or act, which, in any such case, would have a Material Adverse Effect. As
used in this Agreement, "to the knowledge of Sellers" shall mean the collective
knowledge of Alan Gold and Howard Grunfeld (collectively, the "Sellers'

         with the applicable provisions of ERISA and the Internal Revenue Code
         of 1986, as amended (the "Code"), respectively, with respect to each
         Plan.

                           (ii) Each of the Plans that is intended to qualify
         under Section 401(a) of the Code does so qualify and is exempt from

         Sellers have not incurred any liability with respect to any Plan under

         and no event has occurred, and there exists no condition or set of
         circumstances which could result in the imposition of any material
         liability under ERISA (including, without limitation, Title I or Title
         IV of ERISA), the Code or other applicable law with respect to any of
         the Plans.

                           (vi) No Plan, other than a Plan which is an employee

         former employees of Sellers engaged in the operations of the Business
         beyond their retirement or other termination of service with Sellers
         (other than coverage mandated by applicable law or benefits the full
         cost of which is borne by the current or former employee (or his or her
         beneficiary)).

                           (vii) Except as set forth on Schedule 3.01(k) hereto,

         Property Rights") listed on Schedule 3.01(h)(ii) hereto, together with
         Sellers' rights in the Owned Software, constitute all


                                       18
   24

         Business Property Rights of Sellers reasonably necessary to, or
         primarily used in connection with, the conduct of the Business. To the
         knowledge of Sellers, except as set forth on such Schedule, Sellers own
         or have valid rights to use all Business Property Rights without
         conflict with the rights of others. No person has advised Sellers of
         or, to the knowledge of Sellers, threatened to make, any claims that
         the operations of the Business are in violation of or infringe upon any
         such Business Property Rights or any other proprietary or trade rights
         of any third party.

                  (m) Software.

                           (i) The Owned Software listed on Schedule
         3.01(m)(i)-l hereto comprises all of the operating and applications
         computer software programs and databases that have been licensed by
         Sellers to any customer of the Business or as to which Sellers have
         agreed to provide services to any customer of the Business, in each
         case, pursuant to the contracts listed on Schedule 3.01(q) hereto. The
         Owned Software and the Licensed Software listed on Schedule
         3.01(m)(i)-2 hereto comprise all of the operating and applications
         computer software programs and databases used by Sellers in connection
         with the operations of the Business, the licensing, servicing,
         developing, or maintaining of the Owned Software or otherwise used by
         Sellers in the Business.

                           (ii) Except as set forth on Schedule 3.01(m)(i)-l
         hereto and except for the rights of the customers of the Business under
         the contracts listed on Schedule 3.01(q) hereto and the rights of the
         parties to the marketing agreements listed on Schedule 3.01(h)(iv)
         hereto, Sellers have good and marketable title to all Owned Software,
         free and clear of all liens, charges, pledges, security interests, or
         other encumbrances of any nature whatsoever. Sellers hold valid
         licenses to all Licensed Software, subject, in any event, to the terms
         of any agreements relating to the Licensed Software. To the knowledge
         of Sellers, none of the Owned Software, and no use by Sellers of the
         Licensed Software, infringes upon or violates any patent, copyright,
         trade secret or other proprietary right of any other person and no
         claim with respect to any such infringement or violation is threatened.

                           (iii) Sellers possess or have access to (i) to the
         extent required to conduct the Business, the source and object codes
         for all Owned Software and, to the extent


                                       19
   25

         permitted under the respective license agreements, for all the Licensed
         Software used by Sellers in the conduct of the Business and (ii) all
         other technical materials, guidelines and other written materials
         pertaining to the Owned Software or, to the knowledge of Sellers, the
         Licensed Software. Upon consummation of the transactions contemplated
         by this Agreement, Buyers will (A) own all the Owned Software, free and
         clear of all claims, liens, encumbrances, obligations and liabilities,
         except (x) for the rights of customers under the contracts listed on
         Schedule 3.01(q) hereto and the rights of the parties to the marketing
         agreements listed on Schedule 3.01(h)(iv) hereto, and (y) as set forth
         on said Schedule 3.01(m)(i)-l hereto, and (B) have, pursuant to a valid
         and binding assignment thereof hereunder, a valid license to use all
         Licensed Software in the Business without violation or infringement of
         the respective license agreements relating thereto, to the extent
         permitted by such license agreements. To the extent that Buyers shall
         identify, at any time or from time to time during the three-month
         period following the Closing Date, any Licensed Software for which no
         such valid license has been assigned, Sellers shall promptly use best
         efforts to obtain such licenses and transfer, assign and deliver same
         to Buyers, which shall be deemed for all purposes to be included in the
         definition of Assets hereunder as provided in Section 1.01 hereof.

                           (iv) To the knowledge of Sellers, any programs,
         modifications, enhancements or other inventions, improvements,
         discoveries, methods or works of authorship included in the Owned
         Software that were created by employees of Sellers were made in the
         regular course of such employees' employment with Sellers using
         Sellers' facilities and resources and, as such, constitute "works made
         for hire".

                  (n) Use of Real Property. The real property as set forth on
Schedule 3.01(h) hereto are used and operated in material compliance and
conformity with all applicable leases, contracts, licenses and permits. Sellers
have not received notice of any material violation of any applicable zoning or
building regulation, ordinance or other law, order, regulation or requirement
relating to the conduct of the Business or to the Assets and, to the knowledge
of Sellers, there is no such violation. To the knowledge of Sellers, all
buildings used in the operations of the Business substantially conform with all
applicable ordinances, codes, regulations and requirements, and


                                       20
   26

no law presently in effect or condition precludes or materially restricts
continuation of the present use of such properties.

FAULTS AND DEFECTS.

                  (p) Compliance With Law; Permits. Except as set forth on
Schedule 3.01(p) hereto, to the knowledge of Sellers, the conduct of the
Business by Sellers does not violate any federal, state or local laws, statutes,
ordinances, rules, regulations, decrees, orders, permits or other similar items
in force on the date hereof that are applicable to the Business, other than any
such violation which would not or would not reasonably be expected to have a
Material Adverse Effect. Except as set forth on Schedule 3.01(p) hereto, Sellers
have all material governmental licenses, franchises and permits required under
applicable law for the conduct of the Business as currently conducted and, to
the knowledge of Sellers, the Business is being conducted in compliance with all
such licenses, franchises and permits. Schedule 3.01(p) hereto lists all
material licenses, franchises and permits held by Sellers.

                  (q) Customer Contracts.

         such customers, (B) all contracts between Sellers and the customers of
         the Business pursuant to which Sellers have licensed any Owned Software

         shall be made available for review by Buyers upon their reasonable
         request.

         hereto and except for contracts under which Sellers are not currently
         obligated to supply any product or provide any service, no such
         contract contains a prohibition on the assignment thereof without the
         consent of the other party thereto.

                           (iii) Except as set forth on said Schedule 3.01(q)
         hereto, since December 31, 1996, Sellers have not with respect to the
         Business had any contracts with customers terminated prior to the
         expiration date thereof or been notified in writing by any customer of
         its intention to terminate any contract listed on Schedule 3.01(q)
         hereto prior to the expiration date thereof that, in the aggregate,
         accounted for more than 5% of the revenues of the Business during the
         nine-month period ended December 31, 1996 (and, to the knowledge of
         Sellers, no customer has notified Sellers in writing that it would, in
         the event of the sale of the Business, terminate any such contract).
         Except as set forth on Schedule 3.01(q) hereto, since December 31,
         1996, Sellers have not received written notice from any customer of the

         Schedule 3.01(q) hereto sets forth all outstanding contract proposals
         relating to the Business for which a contract has been requested for
         goods or services involving fees in excess of $25,000 per annum.

                  (r) Taxes.

         penalties and any other additions to tax or additional amounts imposed
         by any governmental or taxing authority, or liability for such amounts
         as a result of Seller being a member of an affiliated, consolidated,
         combined or unitary group or being a party to any agreement or
         arrangement whereby Sellers may be liable for Taxes of any other person
         for any period prior to (or up to and including) the close of business
         on the day prior to the Closing Date.

                           (ii) Sellers have paid to the appropriate taxing
         authority, all Taxes owed by Sellers with respect to the operations of

may be limited by applicable equitable principles or by bankruptcy, insolvency,
reorganization, moratorium, or similar laws from time to time in effect
affecting the enforcement of creditors' rights generally. All of the issued and
outstanding capital stock of Sub is owned by HMS. Except for the affirmative
vote of HMS, under the laws of the State of Delaware, the authorization of no
other person or entity is required to consummate the transactions contemplated
herein by virtue of any such person or entity having an equitable or beneficial
interest in Sub.

                  (c) Effect of Agreements. The execution and delivery by Buyers
of this Agreement and the Ancillary Agreements, and the performance by Buyers of
their respective obligations hereunder and thereunder, will not violate any
provision of law, any order of any court or other agency of government, the
Certificates of Incorporation or By-laws of Buyers or any judgment, award or
decree or any indenture, agreement or other instrument to which Buyers are
parties or by which Buyers or their properties or assets are bound or affected,
or conflict with, result in a breach of or constitute (with due notice or lapse
of time or both) a default under, any such indenture, agreement or other
instrument, or result in the creation or imposition of any lien, charge or
encumbrance of any nature whatsoever upon any of the properties or assets of
Buyers.

                  (d) Litigation. There is no action, suit, investigation or
proceeding pending or, to the knowledge of Buyers, threatened against or
affecting Buyers before any court or by or before any governmental body or
arbitration board or tribunal that might enjoin or prevent the consummation of
the transactions contemplated by this Agreement. For purposes of 

                                       25
   31
this Agreement, "to the knowledge of Buyers" shall mean the collective knowledge
of Paul J. Kerz and Phillip Siegel (collectively, the "Sellers' Officers"), the
President and Chief Executive Officer and the Chief Financial Officer,
respectively, of HMS. "Knowledge" when used in this context shall mean, as to
the facts or circumstances represented: (i) actual knowledge of any one of the
Buyers' Officers; and (ii) knowledge that any one of the Buyers' Officers should
reasonably be expected to possess after due inquiry.

                  (e) Governmental Approvals. No approval, authorization,
consent or order or action of or filing with any court, administrative agency or
other governmental authority is required for the execution and delivery by
Buyers of this Agreement or the Ancillary Agreements or the consummation by
Buyers of the transactions contemplated hereby or thereby.

                  (f) Broker's or Finder's Fees. All negotiations relative to
this Agreement and the transactions contemplated hereby have been carried out by
Buyers directly with Sellers, without the intervention of any person on behalf
of Buyers in such a manner to give rise to any claim by any person against
Sellers for a finder's fee, brokerage commission or similar payment.

                  (g) Other Information. None of the information furnished by
Buyers to Sellers in this Agreement, the exhibits hereto, the schedules
identified herein, or in any certificate or other document to be executed or
delivered pursuant hereto by Buyers at or prior to the Closing Date, is, or on
the Closing Date will be, false or incomplete or contains, or on the Closing
Date will contain, any misstatement of material fact.

         organization of the Business intact, keep available the services of
         those officers and employees currently engaged in the operations of the
         Business and preserve their present relationships

   32

         with customers of, and all other persons having business dealings with,
         the Business;

                      (ii) maintain all the assets and properties deemed
         reasonably necessary for the conduct of the Business in good repair,

         perform all their material obligations without default.

                  (b) Between the date of this Agreement and the Closing Date,
Sellers shall, upon reasonable prior notice, afford the representatives of
Buyers reasonable access during normal business hours to the offices,

                  (c) Between the date of this Agreement and the Closing Date,
Sellers shall not, except as required by generally accepted accounting
principles, with respect to the operations of the Business (i) utilize
accounting principles different from those used in the preparation of the

connection with the assignment of the contracts, agreements, licenses, leases,
sales orders, purchase orders and other commitments to be assigned to Buyers
pursuant hereto (other than those listed on Schedule 1.03 hereto); provided,
however, that Buyers shall bear the expense of posting any performance bonds and
any reasonable and necessary special travel expenses of Sellers' required to
obtain such consents, waivers and approvals, subject to Buyers' prior approval
and reimbursement for travel expenses consistent with Buyers' existing policies.

                                       27

                  (e) As of the Closing Date, Sellers shall have paid any amount
owed (or that will be owed as of the Closing Date) by such Sellers to any
Retained Employee, in respect of salary, bonus or other compensation. To the
extent that amounts to be paid to any Retained Employee in reimbursement of
expenses incurred by such Retained Employee on behalf of Sellers shall be unpaid
as of the Closing Date, Sellers shall pay such amounts in accordance with
Sellers' customary practice upon receipt of a duly prepared claim therefor
properly submitted by such Retained Employee.

                  (f) Between the date hereof and the Closing Date, Sellers
shall not enter into any transaction or make any agreement or commitment, or
permit any event to occur, which would result in any of the representations,
warranties or covenants of Sellers contained in this Agreement not being true
and correct at and as of the time immediately after the occurrence of such
transaction or event.

                  SECTION 4.02 Confidentiality. The contents of this Agreement
shall be kept confidential between the parties, except as otherwise required by
law, including but not limited to the provisions of the federal securities laws,
and except that each party may reveal and discuss the contents with its
professional advisors, including attorneys and accountants. In addition, the
parties may mutually agree in writing as to the disclosure of the subject

consideration paid to Sellers, including any liabilities assumed pursuant
hereto) among the Assets and the covenant not to compete granted pursuant to the
Non-Compete Agreement. The Allocation Schedule shall be reasonable and shall be
prepared in accordance with Section 1060 of the Code and the regulations
thereunder. Buyers and Sellers each agree to file Internal Revenue Service Form

                                       28

                  SECTION 4.04 Preparation of Certain Financial Information.

                  (a) After the Closing Date, at the reasonable request of
Buyers, but only in contemplation of and in order to comply with the rules and
regulations (the "SEC Rules") of the Securities and Exchange Commission (the
"SEC"), Sellers shall cause the independent accountants of Sellers to prepare,
at the election of Buyers, audited or compiled financial statements for the
Business for the period commencing on January 1 of the year that is five years
(or such shorter period as is permissible under the SEC Rules) prior to the end
of the year immediately prior to the date such request is made, through the
Closing Date, it being understood and agreed by Sellers and Buyers that such
assistance shall include, without limitation, (i) providing Buyers and their
representatives with all necessary financial information and data relating to
the Business for such periods, (ii) making available to Buyers all employees of
Sellers or any of their affiliates deemed necessary by Buyers to assist in the
preparation of such financial statements, and (iii) delivering a management
representation letter.

                  (b) The fees and expenses of such independent accountants in
preparing audited and/or compiled financial statements for the Business as
provided in this Section 4.04 shall be borne by Buyers, and Buyers shall
compensate Sellers for their out-of-pocket expenses in assisting in such
preparation.

                  (c) After the Closing Date, Buyers shall afford the
representatives of Sellers reasonable access during normal business hours to
such books of account and other financial records of Buyers pertaining to the
Business and acquired by Buyers pursuant to this Agreement as Sellers may
reasonably request in order to prepare, file, amend or respond to questions of
any governmental authority relating to its financial statements and Tax Returns
for any period or portion thereof that Sellers owned the Business. Sellers shall
compensate Buyers for their out-of-pocket expenses incurred in assisting Seller
pursuant to this Section 4.04(c).

                  SECTION 4.05 Certain Tax Matters.

any other additions to such sales and use taxes, imposed by any governmental or
taxing authority upon or incurred by any of the parties hereto in connection
with this Agreement and the transactions contemplated hereby shall be borne by
Buyers. All transfer taxes, including interest, penalties and any other
additions to such transfer taxes, imposed by any governmental or taxing
authority upon or incurred by any of the parties hereto in connection with this
Agreement and the transactions contemplated hereby shall be borne by Sellers.
Sellers and/or Buyers, to the extent required by law and this Section 4.05(a),
shall prepare and file all necessary Tax Returns and other documents with
respect to all such transfer, sales and use taxes. Sellers and Buyers agree to
cooperate in any endeavor to effect a reduction in any such transfer, sales and
use taxes.

                  (b) For all federal, state, local and foreign income and
franchise Tax purposes, each of the parties hereto agrees to treat the
acquisition of the Assets by Buyers, pursuant to the terms and conditions of
this Agreement, as a taxable sale of the assets of Sellers to Buyers solely in
exchange for cash (and the liabilities assumed by Buyers from Sellers).

                  (c) Sellers shall be responsible for and shall pay any and all
Taxes with respect to the operations of the Business relating to all periods
prior to the Closing Date and Buyers shall be responsible for and shall pay any
and all Taxes with respect to the operations of the Business relating to periods
commencing the Closing Date.

                  SECTION 4.06 Insurance. Between the date of this Agreement and
the Closing Date, Buyers shall use reasonable efforts to obtain policies of
fire, liability, workers' compensation and other forms of insurance in such
amounts and against such risks as Buyers deem appropriate, and Sellers shall
reasonably cooperate with Buyers in obtaining such insurance.

                  SECTION 4.07 Retention of Employees; Benefits.

                  (a) Offers of Employment. Effective immediately as of the
Closing Date, Buyers shall offer to continue the employment, at will, or
consultancy of all employees or consultants that, at Buyers' request, Sellers
have listed on Schedule 4.07(a) hereto on terms that are initially no less
favorable than the terms of their employment or consultancy by Sellers. Sellers
shall promptly notify Buyers if any employee of, or consultant to, the Business
shall announce his or her intention not to accept such offer by Buyers. The
employees and consultants listed on 

                                       30
   36
Schedule 4.07(a) hereto who accept Buyers' offer of employment or consultancy
are herein referred to collectively as the "Retained Employees".

                  (b) Benefits. Following the Closing Date, Retained Employees
(excluding consultants unless otherwise indicated on Schedule 4.07(a)) will be
afforded the opportunity to participate in benefits and equity acquisition
programs that currently are available to employees of HMS and on similar terms
of participation; provided, however, that following the Closing Date, Retained
Employees shall continue their existing medical insurance on the current terms
thereof, subject to such changes as Buyers may implement in the future but which
shall accord the Retained Employees health benefits comparable to their current
arrangement. In the event during the first twelve months after the Closing Date,
Buyers shall make a change in the medical insurance covering the Retained
Employees and in connection therewith require a contribution from the Retained
Employees toward the cost of medical insurance, Buyers shall cause the Retained
Employees to be given an increase in compensation equal to the amount of the
required contribution.

                  (c) No Offer of Employment. Nothing in this Agreement, express
or implied, shall confer upon any employee of Sellers engaged in the Business,
or any representative of any such employee, any rights or remedies, including
any right to employment or continued employment for any period, of any nature
whatsoever, whether as third-party beneficiary or otherwise, it being understood
and agreed that any such employment shall, to the maximum extent permitted by
applicable law, be employment at will.

                  (d) Buyers' Own Investigation. Prior to the Closing Date,
Sellers shall, upon reasonable prior notice, afford Buyers reasonable access
during normal business hours to the employees of, and consultants to, Sellers
listed on Schedule 4.07(a) hereto to permit Buyers to evaluate and make their
own investigation with respect to each such employee and consultant, and Sellers
shall not be liable to Buyers for the acts or omissions of any Retained Employee
after the Closing Date.

                  SECTION 4.08 Further Assurances. From time to time following
the Closing Date, Sellers shall execute and deliver, or cause to be executed and
delivered, to Buyers such bills of sale, deeds, endorsements, assignments and
other good and sufficient instruments of conveyance and transfer, in form
reasonably satisfactory to Buyers and their counsel, as Buyers may reasonably
request or as may be otherwise reasonably necessary to 

                                       31
   37
vest in Buyers all the right, title and interest of Sellers in, to or under, and
put Buyers in possession of, any part of the Assets.

                  SECTION 4.09 No Solicitation; Acquisition Proposals. From the
date of this Agreement until the Closing Date or until this Agreement is
terminated as provided in Article VIII, Sellers will not directly or indirectly
(i) solicit or initiate (including by way of furnishing any information)
discussions with or (ii) enter into negotiations or agreements with, or furnish
any information to, any corporation, partnership, person or other entity or
group (other than Buyers, an affiliate of Buyers or their authorized
representatives pursuant to this Agreement) concerning any proposal for a
merger, sale of substantial assets, sale of shares of stock or securities or
other takeover or business combination transaction (an "Acquisition
Transaction") involving the Business; and Sellers will instruct their officers,
directors, advisors and other financial and legal representatives and
consultants not to take any action contrary to the foregoing provisions of this
sentence; provided, however, that the actions prohibited by the foregoing
clauses (i) and (ii) shall be subject to any action taken by the Boards of
Directors of Sellers in the exercise of their good faith judgment as to their
fiduciary duties to their respective stockholders, which judgment is based upon
the advice of independent counsel that a failure of the Boards of Directors to
take such action would be likely to constitute a breach of their fiduciary
duties to their respective stockholders. Sellers will notify Buyers promptly in
writing if Sellers become aware that any inquiries or proposals are received by,
any information is requested from, or any negotiations or discussions are sought
to be initiated with Sellers with respect to an Acquisition Transaction and will
immediately after receipt provide to Buyers a copy of any letter, proposal or
other document in which any proposal for an Acquisition Transaction is made or
expressed. Sellers will immediately cease any existing activities, discussions
or negotiations with any third parties which may have been conducted on or prior
to the date hereof with respect to an Acquisition Transaction and shall direct
and use reasonable efforts to cause their officers, advisors and representatives
not to engage in any such activities, discussions or negotiations.

         pursuant to this Agreement;

                           (iii) any liabilities or obligations (whether

         suit or proceeding based on an event occurring or claim arising on and
         after the Closing Date; and

         compliance with any federal, state or local laws, statutes, ordinances,

                  SECTION 7.04 Conditions of Indemnification. The respective
obligations and liabilities of Sellers, on the one hand, and Buyers, on the
other hand (the "indemnifying party"), to the other (each, collectively, the
"party to be indemnified") under Sections 7.02 and 7.03 hereof with respect to
claims resulting from the assertion of liability by third parties shall be
subject to the following terms and conditions:

                  (a) within 10 days after receipt of notice of commencement of
any action or the assertion in writing of any claim by a third party, the party
to be indemnified shall give the indemnifying party written notice thereof
together with a copy of such claim, process or other legal pleading, and the
indemnifying party shall have the right to undertake the defense thereof by
representatives of its own choosing;

                  (b) in the event that the indemnifying party, by the 20th day
after receipt of notice of any such claim (or, if earlier, by the tenth day
preceding the day on which an answer or other pleading must be served in order
to prevent judgment by default in favor of the person asserting such claim),
does not elect to defend against such claim, the party to be indemnified will
(upon further notice to the indemnifying party) have the right to undertake the
defense, compromise or settlement of such claim on behalf of and for the account
and risk of the indemnifying party, subject to the right of the indemnifying
party to assume the defense of such claim at any time prior to settlement,
compromise or final determination thereof, provided that the indemnifying party
shall be given at least 15 days prior 

                                       41
   47

written notice of the effectiveness of any such proposed settlement or
compromise; and

                  (c) anything in this Section 7.04 to the contrary
notwithstanding (i) if there is a reasonable probability that a claim may
materially and adversely affect the indemnifying party other than as a result of
money damages or other money payments, the indemnifying party shall have the
right, at its own cost and expense, to compromise or settle such claim, but (ii)
the indemnifying party shall not, without the prior written consent of the party
to be indemnified, settle or compromise any claim or consent to the entry of any
judgment which does not include as an unconditional term thereof the giving by
the claimant or the plaintiff to the party to be indemnified a release from all
liability in respect of such claim.

                  SECTION 7.05 Direct Claims. Any claim by the party to be
indemnified for indemnification other than with respect to claims resulting from
the assertion of liability by third parties (a "Direct Claim") will be asserted
by giving the indemnifying party reasonably prompt written notice thereof, and
the indemnifying party will have a period of twenty (20) calendar days within
which to respond in writing to such Direct Claim. If the indemnifying party does
not so respond within such twenty (20) calendar day period, the indemnifying
party will be deemed to have rejected such claim, in which event the party to be
indemnified will be free to pursue another remedy to which it may be entitled.

                  SECTION 7.06 Certain Information. In connection with any
indemnification provided in this Article VII, the indemnified party shall
cooperate in all reasonable requests of the indemnifying party and each party
shall furnish or cause to be furnished to the other (at reasonable times and at
the expense of the party requesting such information) upon request as promptly
as practicable such information (including access to books and records of the
Business and to employees familiar with the affairs thereof) and assistance
relating to the Business as is reasonably necessary for the defense of any
claim, suit or proceeding.

                  SECTION 7.07 Limitations on Liability of Sellers.

                  (a) The indemnities set forth in Section 7.03 and all
representations, warranties and covenants hereunder shall survive for a period
of one year following the Closing Date, unless such indemnities,
representations, warranties and covenants of the Sellers hereunder pertain to
Tax claims, in which event they 

                                       42
   48
shall survive until expiration of the applicable statute of limitation period.
Upon the expiration of such respective periods, the Sellers shall have no
liability for Damages under such indemnification provisions unless the Buyers
have been given notice of a claim asserting liability by a third party prior to
the expiration of such respective periods and thereafter provides notice to the
Sellers in the manner provided in Section 7.04 above prior to the expiration of
such periods.

                  (b) If the Sellers become liable for Damages to Buyers
hereunder, the Sellers shall be entitled to a credit or offset against such
liability of an amount equal to $20,000 (the "Threshold"). At such time as the
aggregate of all Damages exceeds the Threshold, the Buyers shall be entitled to
recover from the Sellers any and all amounts for which a claim for indemnity has
been made, without regard to the Threshold.

                  (c) If the Sellers become liable for Damages to Buyers
hereunder, in no event shall the liability of the Sellers exceed in the
aggregate 15% of the Purchase Price; provided, however, that nothing in this
section 7.07(c) shall limit, in any manner, any remedy at law or in equity to
which Buyers may be entitled as a result of intentional fraud by any party to
this Agreement.

                                VIII. TERMINATION

                  SECTION 8.01 Termination. This Agreement may be terminated at
any time prior to the Closing Date:

                  (a) by Buyers, if the conditions set forth in Section 6.01
shall not have been complied with or performed in any material respect by
Sellers on or before 120 days following the date hereof (except 180 days
following the date hereof in the case of the condition set forth in Section
6.01(e)) and such noncompliance or nonperformance shall not have been waived,
cured or eliminated (or by its nature cannot be cured or eliminated);

                  (b) by Sellers, if the conditions set forth in Section 6.02

noncompliance or nonperformance shall not have been waived, cured or eliminated
(or by its nature cannot be cured or eliminated);

                  (c) by Buyers or Sellers, in the event the Closing Date has

                                       43
   49
hereto may agree in writing (unless such event has been caused by the breach of
this Agreement by the party seeking such termination);

                  (d) by either Sellers or Buyers if (i) there shall be a final
nonappealable order of a federal or state court in effect preventing
consummation of the transactions contemplated by this Agreement or (ii) there
shall be any action taken, or any statute, rule, regulation or order enacted,
promulgated or issued or deemed applicable to the transactions contemplated by
this Agreement by any governmental entity which would make consummation of the
transactions contemplated by this Agreement illegal; or

                  (e) by either Sellers or Buyers if there shall be any action
taken, or any statute, rule, regulation or order enacted, promulgated or issued
or deemed applicable to the transactions contemplated by this Agreement by any
governmental entity, which would (i) prohibit the Sellers' ownership or
operation of all or a material portion of the Assets or the Business, or compel
Buyers to dispose of or hold separate all or a material portion of the Assets or
the Business or of HMS and its subsidiaries taken as a whole, as a result of the
transactions contemplated by this Agreement or (ii) render Sellers or Buyers
unable to consummate the transactions contemplated by this Agreement, except for
any waiting period provisions.

                  SECTION 8.02 Effect of Termination. In the event of the
termination of this Agreement pursuant to Section 8.01 hereof, this Agreement
shall thereafter become void and have no effect, and no party hereto shall have
any liability to the other party hereto or its stockholders, directors or
officers in respect thereof, except as provided in Section 9.02 hereof and
except that nothing herein shall relieve any party from liability for any
willful breach hereof. Notwithstanding the foregoing, in the event of the
termination of this Agreement pursuant to Section 8.01 hereof, Buyers shall not
solicit any of Sellers' customers as of the date of termination within the scope
of Sellers' then current contracted services to such customers for a period of
one year from the date of such termination or until the expiration of Sellers'
then current contract with such customers, whichever is the shorter period;
provided, however, the foregoing restriction shall not apply to any of Sellers'
customers (the "Overlap Customers") for whom Buyers are providing similar
services; provided further, however, that for such Overlap Customers, Buyers
shall not expand the scope of services which they are providing to such Overlap
Customers until the restriction herein expires as provided above.

   50

                  SECTION 9.01 Bulk Transfer Laws. Buyers hereby waive
compliance by Sellers with any applicable bulk transfer laws including, without
limitation, the bulk transfer provisions of the Uniform Commercial Code of any
state, or any similar statute that may be applicable to the sale or transfer of
the Assets hereunder with respect to the transactions contemplated hereby.

                  SECTION 9.02 Expenses, Etc. Whether or not the transactions
contemplated by this Agreement are consummated, Sellers, on the one hand, and
Buyers on the other hand, shall not have any obligation to pay any of the fees
and expenses of the other party incident to the negotiation, preparation and
execution of this Agreement, including the fees and expenses of counsel,
accountants, investment bankers and other experts. Sellers, on the one hand, and
Buyers on the other hand, will indemnify the other and hold the other harmless
from and against any claims for finder's fees or brokerage commissions in

or understanding between such indemnifying party and any third party.

                  SECTION 9.03 Risk of Loss. Sellers assume all risk of
condemnation, destruction, loss or damage due to fire or other casualty from the
date of this Agreement through the Closing Date. If the condemnation,
destruction, loss or damage is such that the Business is interrupted or
curtailed or the Assets are materially affected, then Buyers shall have the
right either to terminate this Agreement or to continue with the Closing
provided that Buyers shall have received from Sellers an assignment of all
insurance benefits paid or to be paid to Sellers as a result of such casualty
(which benefits Sellers shall agree so to assign following a request from Buyers
therefor).

                  SECTION 9.04 Execution in Counterparts. This Agreement may be
executed in one or more counterparts, each of which shall be deemed an original,

postage prepaid and return receipt requested; or (iii) when otherwise personally
delivered to the addressee.

                  SECTION 9.06 Waivers. Sellers, on the one hand, and Buyers, on
the other hand, may, by written notice to the other, (i) extend the time for the
performance of any of the obligations or other actions of the other under this
Agreement; (ii) waive any inaccuracies in the representations or warranties of
the other contained in this Agreement or in any document delivered pursuant to
this Agreement; (iii) waive compliance with any of the conditions or covenants
of the other contained in this Agreement; or (iv) waive performance of any of
the obligations of the other under this Agreement. Except as provided in the
preceding sentence, no action taken pursuant to this Agreement, including,
without limitation, any investigation by or on behalf of Sellers, on the one
hand, and Buyers, on the other hand, shall be deemed to constitute a waiver by
the party taking such action of compliance with any representations, warranties,
covenants or agreements contained in this Agreement. The waiver by Sellers, on
the one hand, and Buyers, on the other hand, of a breach of any provision of
this Agreement shall not operate or be construed as a waiver of any subsequent
breach.

                  SECTION 9.07 Amendments, Supplements, Etc. At any time this
Agreement may be amended or supplemented by such additional agreements, articles
or certificates as may be determined by the parties hereto to be necessary,
desirable or expedient to further the purposes of this Agreement, or to clarify
the intention of the parties hereto, or to add to or modify the covenants, terms
or conditions hereof or to effect or facilitate any governmental approval or
acceptance of this Agreement or to effect or facilitate the consummation of any
of the transactions contemplated hereby. Any such instrument must be in writing
and signed by the parties.

                  SECTION 9.08 Entire Agreement. This Agreement, its Exhibits
and Schedules including, without limitation, the Ancillary Agreements and the
documents executed on the Closing Date in connection herewith, constitute the
entire agreement among the parties hereto with respect to the subject matter
hereof and supersede all prior agreements and understandings, oral and written,
between the parties hereto with respect to the subject matter hereof. No
representation, warranty, promise, inducement or statement of intention has been
made by any party which is not embodied in this Agreement or such other
documents, and neither Sellers, on the one hand, nor Buyers, on the other hand,
shall be bound by, or be liable for, any alleged 

                                       47
   53
representation, warranty, promise, inducement or statement of intention not
embodied herein or therein.

                  SECTION 9.09 Applicable Law; Jurisdiction.

                  (a) This Agreement shall be governed by and construed in
accordance with the laws of the State of New York applicable to contracts made

                  (b) Each Seller hereby irrevocably and unconditionally (i)
submits for itself and its property in any legal action or proceeding relating
to this Agreement and the Ancillary Agreements to the non-exclusive general
jurisdiction of the Courts of the State of New York, the courts of the United
States of America for the Southern District of New York, and appellate courts
from any thereof; (ii) consents that any such action or proceeding may be
brought in such courts and waives any objection that it may now or hereafter
have to the venue of any such action or proceeding in any such court or that
such action or proceeding was brought in an inconvenient court and agrees not to
plead or claim the same; and (iii) agrees that service of process in any such
action or proceeding may be effected by mailing a copy thereof by registered or
certified mail (or any substantially similar form of mail), postage prepaid, to
Seller at its address set forth in Section 9.05 hereof or at such other address
of which the Agent shall have been notified pursuant thereto.

                  SECTION 9.10 Binding Effect; Benefits. This Agreement shall
inure to the benefit of and be binding upon the parties hereto and their
respective successors and assigns. Notwithstanding anything contained in this
Agreement to the contrary, nothing in this Agreement, expressed or implied, is
intended to confer on any person other than the parties hereto or their
respective successors and assigns any rights, remedies, obligations or
liabilities under or by reason of this Agreement.

                  SECTION 9.11 Assignability. Neither this Agreement nor any of
the parties' rights hereunder shall be assignable by any party hereto without
the prior written consent of the other parties hereto.

                  SECTION 9.12 Update to Schedules. The parties acknowledge that
the disclosure schedules of Sellers attached to this Agreement have been
prepared either as of the date of this Agreement or, at the request of the

ordinary manner and shall not have a Material Adverse Effect.
