Schedules describing the Assets as provided in Section 1.01(a) hereof failed to

            (c) Anything herein contained to the contrary notwithstanding, the

            (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

            (iii) all claims or rights against third parties relating to
      liabilities or obligations (including, without limitation, any such

      that are not assumed by Buyer hereunder;

            (iv) all claims for the refund of Taxes (as hereinafter defined) and

            (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
<PAGE>

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 consent with respect to
contracts and claims listed on Schedule 1.03 hereto. With respect to those
contracts and claims of which Sellers shall have failed to obtain consent for
the assignment thereof pursuant to their obligations under 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 (y) for, and
to facilitate, the collection of the moneys due and payable, and to become due
and payable, to Sellers in and under every such contract and claim and in
respect of every such claim and demand, and Sellers shall hold the same for the
benefit of and shall pay the same over promptly to Buyers, subject to due
payment, performance and discharge by


                                      5
<PAGE>

Buyers on behalf of Sellers of all liabilities and obligations of Sellers with
respect to any such contracts and claims that have not been assigned hereunder
but as to which Sellers shall have obtained the full value thereof for the
benefit of Buyers as required hereunder (the "Subcontracted Contracts").

            SECTION 1.04 Ancillary Agreements. In connection with the purchase
and sale of the Assets by Buyers and Buyers' opera tion of the Business from and
after the Closing Date, Sellers hereby covenant and agree to enter into on the
Closing Date the Non-Compete Agreement in the form annexed hereto as Exhibit B
(the "Non-Compete Agreement" and, collectively with the Bill of Sale, the
"Ancillary Agreements").

                 II. CLOSING, PURCHASE PRICE, LIABILITIES, ETC.

            SECTION 2.01 Closing. The closing of the transactions contemplated
by this Agreement shall take place at the offices of Coleman & Rhine LLP, 1120
Avenue of the Americas, New York, New York 10036, on such date 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 date (such date

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 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

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

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.

contemplated hereby or thereby or (ii) is necessary in order that the Business

            (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

            (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

            SECTION 4.07 Retention of Employees; Benefits.

            (a) Offers of Employment. Effective immediately as of the Closing

all employees or consultants that, at Buyers' request, Sellers have listed on

notify Buyers if any employee of, or consultant to, the


                                      30
<PAGE>

Business shall announce his or her intention not to accept such offer by Buyers.
The employees and consultants listed on 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

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


                                      31
<PAGE>

satisfactory to Buyers and their counsel, as Buyers may reasonably request or as
may be otherwise reasonably necessary to 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.

            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


                                      41
<PAGE>

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 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


                                      42
<PAGE>

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 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);


                                      43
<PAGE>

            (b) by Sellers, if the conditions set forth in Section 6.02 shall
not have been complied with or performed in any material respect by Buyers 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 6.02(i)) and such
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 not
occurred on or prior to the close of business 180 days following the date hereof
or such later date as the parties hereto may agree in writing (unless such event
has been caused by the breach of this Agreement by the party seeking such
termina tion);

            (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'


                                      44
<PAGE>

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.

                                IX. MISCELLANEOUS

            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
relation to or in connection with such transactions as a result of any agreement
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).

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

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

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

<PAGE>

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.
