2.6(d) hereof, as follows:

                  (a) Purchaser shall deliver to Seller, payment by wire
transfer of immediately available funds, in the amount of Nine Million Dollars
($9,000,000) plus or minus the Closing Adjustment, if any, such aggregate
payment to be delivered to an account, which account shall be designated by

following the Closing Date, (i) Purchaser agrees to pay Seller (x) the amount,

                  (b) Purchaser shall deliver to State Street Bank and Trust

<Page>
                                                                              17


(x) the amount by which the aggregate Accounts Receivable on the Closing Date
minus the aggregate Accounts Payable and Accrued Expenses on the Closing Date is
less than One Million Eight Hundred Thousand Dollars ($1,800,000), whereupon
such amount shall be deducted from the Purchase Price in accordance with Section

Closing Date is greater than One Million Eight Hundred Thousand Dollars
($1,800,000), whereupon such amount shall be added to the Purchase Price in
accordance with Section 2.6(a).

                  (d) (i) Not later than twenty-one (21) days following the
Closing, Seller may (or, if so requested by Purchaser, Seller shall), at its
sole cost and expense, prepare and deliver to Purchaser a statement setting
forth the aggregate Accounts Receivable, Accounts Payable and Accrued Expenses
as of the Closing Date, together with detailed schedules setting forth the
figures and calculations used to obtain such amounts, certified by an executive
officer of Seller (the "CLOSING STATEMENT"). The Closing Statement shall be
prepared by Seller in good faith and the components of such Closing Statement
shall be in accordance with GAAP applied on a basis consistent with the Pro
Forma Financials and shall be accompanied by all other information necessary to
determine the aggregate Accounts Receivable, Accounts Payable and Accrued
Expenses as of the Closing Date. Seller shall allow Purchaser and its
representatives access at reasonable times after the Closing Date to the books,
records, accounts and work papers of Seller related to the Business and to
Seller's financial employees and accountants involved in the preparation of the
Closing Statement in order to allow Purchaser to examine and determine the
accuracy of the Closing Statement.

                        (ii) Within ten (10) Business Days after the date the
Closing Statement is delivered by Seller to Purchaser, Purchaser shall complete
its examination thereof and may deliver to Seller a written report setting forth
any proposed adjustments to the Closing Statement ("PURCHASER'S DISPUTE
REPORT"). If Purchaser notifies Seller of its acceptance of the Closing
Statement, or if the Purchaser fails to deliver a report of proposed adjustments
to the Closing Statement within the ten (10) Business Day period specified in
the preceding sentence, the Closing Statement shall be conclusive and binding on
the parties as of the last day of such ten (10) Business Day period. Purchaser
and Seller shall use good faith efforts to resolve any dispute as to the Closing
Statement (each a "DISPUTED MATTER"), and any resolution between them as to a
Disputed Matter shall be final, binding and conclusive on the parties hereto.
If, after fifteen (15) days following the receipt by Seller of Purchaser's
Dispute Report, Purchaser and Seller are unable to resolve any Disputed Matter,
such Disputed Matter shall promptly be referred to an Independent Accounting
Firm for resolution. The Independent Accounting Firm shall be instructed to
conduct a review of the Closing Statement and to use every reasonable effort to
make its determination with respect to such Disputed Matter (the
"DETERMINATION") within thirty (30) days of the submission to the Independent
Accounting Firm of such Disputed Matter. Seller shall give the Independent
Accounting Firm access at all reasonable times to the books, records, accounts
and work papers used to prepare the Closing Statement and to Seller's financial
employees and accountants involved in the preparation of the Closing Statement.
Each of Purchaser and Seller shall have the opportunity to make a presentation
to the Independent Accounting Firm and

<Page>
                                                                              18


each shall use its reasonable best efforts to make such presentation, if any, as
promptly as possible following submission to the Independent Accounting Firm of
such Disputed Matter. After completing the Determination, the Independent
Accounting Firm shall deliver notice of the Determination to Purchaser and
Seller and upon receipt thereof, in the absence of fraud or manifest error, the
Determination shall be final, binding and conclusive on the parties hereto with
respect to such Disputed Matter. The final determination of the aggregate
Accounts Receivable (the "FINAL ACCOUNTS RECEIVABLE"), Accounts Payable (the
"FINAL ACCOUNTS Payable") and Accrued Expenses (the "FINAL ACCRUED EXPENSES") as
of the Closing Date shall be the aggregate Accounts Receivable, Accounts Payable
and Accrued Expenses set forth in the Closing Statement as adjusted by any
disputes resolved by the parties and by the Independent Accounting Firm's
Determination, if any. Each of Purchaser and Seller shall bear all costs, fees
and expenses incurred by it in connection with such arbitration, and the
allocation of the costs, fees and expenses of the Independent Accounting Firm as
between Purchaser and Seller shall be paid one-half (1/2) by Purchaser and
one-half (1/2) by Seller.

                        (iii) Within seven (7) days after the determination of
the Final Accounts Receivable, Final Accounts Payable and Final Accrued Expenses
in accordance with Section 2.6(d)(ii):

                              (A) if the Net Final Amount is greater than the
      Net Estimated Amount, then Purchaser shall pay to Seller the amount by
      which the Net Final Amount exceeds the Net Estimated Amount; or

                              (B) if the Net Estimated Amount is greater than
      the Net Final Amount, then Seller shall pay to Purchaser the amount by
      which Net Estimated Amount exceeds the Net Final Amount.

            Notwithstanding any other provision on this Section 2.6(d), no
payment shall be made pursuant to this Section 2.6(d) unless the amount of such
payment exceeds Fifteen Thousand Dollars ($15,000), whereupon the paying party
shall be required to pay the entire amount of such payment to the other party.
Any payment due to a party pursuant to this Section 2.6(d)(iii) shall be made by
wire transfer of immediately available funds to an account designated by the
party entitled to such payment, and the party entitled to such payment shall
provide written wire instructions to the paying party for such account at least
three (3) days prior to the date of payment; PROVIDED, HOWEVER, that if
Purchaser is entitled to a payment pursuant to this Section 2.6(d)(iii),
Purchaser may, in its sole discretion, elect to be paid from the Escrow Account,
whereupon Purchaser and Seller shall deliver a joint notice to the Escrow Agent
in accordance with the Escrow Agreement, instructing the Escrow Agent to make
such payment from the Escrow Account to Purchaser.

            Section 2.7 CLOSING. The closing of the transactions contemplated by
this Agreement (the "CLOSING") shall take place at the offices of Paul, Weiss,
Rifkind, Wharton & Garrison, 1615 L Street, NW, Washington, DC 20036-5694, at

applicable federal, state, local or foreign law, statute, ordinance, rule,
regulation, order, judgment or decree, injunctions, awards, administrative order
or decree, administrative or judicial decision, and any other executive or
legislative proclamation ("LAWS"), this Agreement shall not constitute an

                                                                              21


                  (b) In the event that any Consent referred to in Section
2.11(a) has not been obtained prior to the Closing, Seller shall, at Seller's
sole cost and expense, use its best efforts, and Purchaser shall cooperate with

impracticalities of assignment referred to in Section 2.11(a) after the Closing.

                  (c) To the extent any Consents referred to in Section 2.11(a)

impracticalities of assignment referred to in Section 2.11(a) hereof are
resolved, Seller shall use its reasonable best efforts, at Seller's sole cost
and expense, to (i) provide Purchaser the benefits of any Acquired Assets
referred to in Section 2.11(a), (ii) cooperate in any reasonable and lawful
arrangement designed to provide such benefits to Purchaser, without incurring
any financial obligation to Purchaser, and (iii) enforce for the account and

Assets referred to in Section 2.11(a) against such issuer thereof and all other
parties thereto and/or any other Person (including, without limitation, the
right to elect to terminate in accordance with the terms thereof on the advice
of Purchaser).

                  (d) To the extent that Purchaser is provided the benefits
pursuant to Section 2.11(c) of any Acquired Assets, Purchaser shall perform, on
behalf of Seller, for the benefit of the issuer thereof, all other parties
thereto and/or any other Person, the obligations of Seller thereunder or in
connection therewith, but only to the extent that (i) such action by Purchaser
would not result in any material default thereunder or in connection therewith
and (ii) such obligation would have been an Assumed Liability but for the
non-assignability or non-transferability thereof.

                  (e) In addition to any actions taken in accordance with this
Section 2.11, Seller shall assist Purchaser in novating or obtaining Consents to
the assignment of the Government Contracts and Foreign Government Contracts in

fashion and Purchaser elects, in its sole discretion, to close the transactions
contemplated by this Agreement without obtaining novations or obtaining Consents
to assignments with respect to all of the Government Contracts and Foreign
Government Contracts, then (i) Seller shall prepare novation agreements and all
other documentation necessary to novate any such Government Contracts and
Foreign Government Contracts, and shall deliver such materials to Purchaser for
review and execution within fourteen (14) days after the Closing Date and (ii)
Seller shall cooperate with Purchaser to make alternative arrangements
(satisfactory to Purchaser in its absolute discretion) with respect to the
performance of such Government Contracts and Foreign Government Contracts after
the Closing and until such novations are obtained, including, without
limitation, subcontracting to Purchaser all of Seller's obligations under such
Government Contracts and Foreign Government Contracts, in accordance

faith between Purchaser and Seller.

                                                                              22


                                  ARTICLE III

                    REPRESENTATIONS AND WARRANTIES OF SELLER

             Seller represents and warrants to Purchaser as follows:

            Section 3.1 ORGANIZATION AND QUALIFICATION OF SELLER. Seller is a
corporation duly organized, validly existing and in good standing under the laws
of the jurisdiction of its incorporation, has all requisite corporate power and
authority to own, lease and operate its properties and the Acquired Assets and
to carry on the Business as now being or heretofore conducted. Seller is duly
qualified to do business as a foreign corporation and is in good standing in
each jurisdiction in which the ownership or leasing of its property or the
conduct of the Business requires such qualification, except where the failure to
be so qualified would not have a Business Material Adverse Effect. "BUSINESS
MATERIAL ADVERSE EFFECT," as used in this Agreement, shall mean any event,
change or effect that is or could reasonably be expected to be materially
adverse to the Acquired Assets, condition (financial or otherwise), properties,
liabilities, operations, results of operations, or reasonably anticipated
prospects of the Business, taken as a whole. The copies of the certificate of
incorporation and by-laws of Seller previously delivered to Purchaser or its
counsel, in each case as amended, are true, complete and correct. The minute
books, or comparable records, of Seller contain true, complete and correct
records of all meetings and consents in lieu of meetings of its Boards of
Directors (and any committees thereof) and of its stockholders since the time of
its incorporation, and accurately reflects all transactions referred to in such
minutes and consents in lieu of meeting in all material respects. The stock
books (or analogous ownership records) of Seller are true, complete and correct.

            Section 3.2 AUTHORITY TO EXECUTE AND PERFORM AGREEMENT. Seller has
all requisite power and all authority and approvals required to enter into,
execute and deliver this Agreement, the other Transaction Documents to which it
is or will be a party and each and every transaction contemplated hereby and
thereby and to perform fully its obligations hereunder and thereunder. The Board
of Directors of Seller, in accordance with the terms of Seller's certificate of
incorporation and by-laws, has unanimously adopted a resolution approving and
adopting this Agreement, and no other corporate action by Seller or its
stockholders is required for the due execution, delivery or performance of this
Agreement or the other Transaction Documents. This Agreement has been duly
authorized, executed and delivered by Seller, and on the Closing Date, each of
the other Transaction Documents will be duly authorized, executed and delivered
by Seller. Assuming due execution and delivery hereof and thereof by Purchaser,
this Agreement and each of the other Transaction Documents will be valid and
binding obligations of Seller, enforceable against Seller in accordance with
their respective terms, except that such enforceability may be subject to (i)
bankruptcy, insolvency, reorganization or other similar laws affecting or
relating to enforcement of creditors' rights generally, and (ii) general
equitable principles.

            Section 3.3 FINANCIAL STATEMENTS. The pro forma financial statements
of the Business as of December 31, 1998, 1999 and 2000 (the "PRO FORMA
FINANCIALS"),

<Page>
                                                                              23


which have been delivered to Purchaser, were prepared by Seller in order to
provide Purchaser with a fair representation of the financial position of the
Business and a representation with respect to the financial performance of the
Business. The Business, which represents one (1) division of Seller, is not a
separate corporate entity and has not, except for the Pro Forma Financials, had
its financial operations accounted for as such. The Pro Forma Financials are
complete and correct copies thereof and fairly present, in all material
respects, the financial position of the Business as at such dates, and the
results of operations and changes in financial position of the Business for such
respective periods. (The foregoing pro forma financial statements of the
Business as of December 31, 2000, and for the year then ended are sometimes
herein called the "2000 PRO FORMA FINANCIALS.") The recognition of revenues and
the allocation of gross profits by Seller reflected in The Pro Forma Financials
are, in each case, consistent with GAAP, applied consistently for the periods
covered thereby.

            Section 3.4 ABSENCE OF CERTAIN CHANGES OR EVENTS. Except as set
forth on SCHEDULE 3.4, from December 31, 2000 to the date hereof, there has been
no change in the Acquired Assets, condition (financial or otherwise),
properties, liabilities, operations, results of operations or reasonably
anticipated prospects of the Business, whether or not covered by insurance,
which has resulted in, reasonably could be expected to result in, or which
Seller has reason to believe could reasonably be expected to result in a
Business Material Adverse Effect, and the Seller has no Knowledge of any such
change that is threatened, nor has there been any damage, destruction or loss
affecting the Acquired Assets (financial or otherwise), properties, liabilities,
operations, results of operations or reasonably anticipated prospects of the
Business, whether or not covered by insurance, which has resulted in, reasonably
could be expected to result in, or which Seller has reason to believe could

benefits, nor shall Seller be liable or obligated for any expenses, with respect

subsection (i) of this paragraph.

                  (f) As of the date hereof, the consummation of the
transactions contemplated by this Agreement will not (i) entitle any individual

(ii) accelerate the time of payment or vesting, or increase the amount of any
compensation due, or in respect of, any individual, (iii) result in or satisfy a

consultation and other cooperation and assistance in connection with the
Investigation, the DCAA Mod. 4, -0051 Contract Audit and the DCAA Mod. 31, -0070
Contract Audit; PROVIDED, HOWEVER, that, in no event, shall Purchaser be
required to comply with the obligations set forth in this Section 5.4(c) to the
extent that such compliance would interfere, individually or in the aggregate,
with the responsibilities and duties of such Business Employees to Purchaser.
Seller agrees to promptly reimburse Purchaser for all out-of-pocket costs
incurred by Purchaser or the Business Employees in connection with the
performance of the obligations set forth in this Section 5.4(c).

            Section 5.5 CONFIDENTIALITY. From and after the date of this
Agreement, in the event of the consummation of the transaction contemplated
hereby, Seller shall keep, and shall use reasonable efforts to cause its
employees to keep, any and all confidential and proprietary information relating

limited to, customer lists and related information) of the Business, services
and know-how relating to the Business ("CONFIDENTIAL Information") confidential
and shall not disclose such Confidential Information to any Person; PROVIDED,
HOWEVER, that Seller may disclose such information that (i) is or becomes
publicly available other than by disclosure by Seller or any agent thereof or
(ii) Seller is required to disclose by Law or in order to enforce the terms of
this Agreement, but Seller will give Purchaser adequate advance notice so that
Purchaser may seek a protective order or take other reasonable actions to
preserve the confidentiality of such information. In the event that the
transactions contemplated hereby are not consummated, the terms of that certain
confidentiality agreement between Seller and Purchaser (the "CONFIDENTIALITY
AGREEMENT") shall continue to apply in full force and effect in accordance with
the terms thereof.

action which will have the effect of delaying, impairing or impeding the receipt
of any required regulatory approvals and will use its reasonable efforts to
secure such approvals as promptly as possible.

            Section 5.7 INSURANCE PROCEEDS, LITIGATION RIGHTS. In the event that
any property used primarily in the conduct of the Business or otherwise material
to the Business, in each case, owned or leased by Seller suffers any material
damage, destruction or other casualty loss, and the Closing occurs in accordance

proceeds received by Seller with respect to such damage or loss and (ii) all
rights of Seller with respect to any causes of action, whether or not litigation
has commenced on the Closing Date, in connection with such damage or loss.
Nothing in this Section 5.7 shall be construed to limit or prejudice Purchaser's
rights and remedies under this Agreement, including, without limitation,
Purchaser's right not to consummate the transactions contemplated hereby if all
of the conditions set forth in Section 6.2 are not satisfied or waived, in the
sole discretion of Purchaser.

date hereof to the Closing Date, Purchaser shall promptly notify Seller of any
litigation that, if adversely determined, would impair the ability of Purchaser
to consummate the transactions contemplated hereby.

            Section 5.10 AGREEMENTS. From the date hereof through the Closing

of the Agreement, the parties hereto will use reasonable efforts to satisfy (or
cause to be satisfied) all the conditions precedent to their respective
obligations.

            Section 5.13 EXCLUSIVITY. As an inducement to Purchaser to enter
into this Agreement, and in consideration of the time and expense which it has
devoted and will devote to the transactions contemplated hereby during such
period, subsequent to the execution of this Agreement and until the earlier of
(i) the Closing Date and (ii) the termination of this Agreement in accordance
with Section 8.1, neither Seller nor any of its representatives (including,
without limitation, any investment banker, attorney or accountant retained or
acting on behalf of Seller or any shareholder, director, officer or employee of
Seller) will, directly or indirectly, (i) initiate, solicit, encourage or
respond to any inquiry or proposal with respect to a merger, consolidation,
share exchange, business combination, liquidation, or dissolution (unless such

not adversely affect, Purchaser's rights under this Agreement) or sale of all or
a portion of the assets of the Business or any purchase of any of the

(ii) enter into any discussions, negotiations or agreements concerning an
Acquisition Proposal with, or disclose any information concerning the Business,
its business or properties or afford any access to its properties, books and
records to, or otherwise assist or facilitate any effort relating to an
Acquisition Proposal, by any Person. Seller will immediately cease any existing

            Section 5.14 NON-COMPETITION; NON-SOLICITATION.

                  (a) Each of Seller, John Kim and Terri Kim hereby covenants
and agrees that, from and after the Closing and until the third (3rd)
anniversary of the Closing Date, Seller, John Kim and Terri Kim, as the case may
be, shall not directly or indirectly participate in the management, operation or
control of, or have any financial or ownership interest in, or otherwise
financially assist, or permit its name to be used in connection with, any
business or entity that (i) engages in any business competitive with the
Business or (ii) manufactures, markets or distributes any products or services
that compete with the Business, in each case (i) and (ii) above, in any market,
jurisdiction or territory in which Purchaser or any of its Affiliates are then
engaging in the Business.

                  (b) Seller acknowledges and agrees that if Seller breaches any
provision of this Section 5.14 or of Section 5.5, any remedy at law would be
inadequate and insufficient and would cause Purchaser irreparable harm and that
Purchaser, in addition to seeking monetary damages in connection with any such
breach, shall be entitled to specific performance and injunctive and other
equitable relief to prevent or restrain a breach of this Section 5.14 or of
Section 5.5 or to enforce the provisions hereof without the requirement of
posting bond or other security. Each of John Kim and Terri Kim acknowledges and
agrees that if John Kim or Terri Kim, as the case may be, breaches any provision
of Section 5.14(a), any remedy at law would be inadequate and insufficient and
would cause Purchaser irreparable harm and that Purchaser, in addition to
seeking monetary damages in connection with any such breach, shall be entitled
to

                                                                              44


specific performance and injunctive and other equitable relief to prevent or
restrain a breach of Section 5.14(a) or to enforce the provisions hereof without
the requirement of posting bond or other security. If any of the covenants
contained herein, or any part hereof, is hereafter construed to be invalid or
unenforceable, the same shall not affect the remainder of the covenant or
covenants, which shall be given full force and effect, without regard to the
invalid portions. If any of the covenants contained herein, or any part hereof,
is held to be unenforceable because of the duration of such provision or the
geographic area covered thereby or for any other reason, the parties agree that
the court making such determination shall have the power to reduce the duration
and/or geographic area of such provision or otherwise modify the terms of any
such covenant and, in its reduced form, said provision shall then be
enforceable.

                  (c) Seller hereby covenants and agrees that, from and after
the Closing and until the second (2nd) anniversary of the Closing Date, Seller
shall not directly or indirectly, hire, solicit or encourage to leave the
employment of Purchaser or any of its Affiliates, any employee of Purchaser or
any of its Affiliates or hire any such employee who has left the employment of
Purchaser or any of its Affiliates within one (1) year of the termination of
such employee's employment with Purchaser or any of its Affiliates; PROVIDED,
HOWEVER that this Agreement shall in no way restrict Seller from soliciting for
employment (and subsequently hiring) any Person through the means of an
advertisement for employment in a newspaper of general circulation or by other
similar means.

                  (d) Purchaser hereby covenants and agrees that, from and after
the Closing and until the second (2nd) anniversary of the Closing Date,
Purchaser shall not directly or indirectly, hire, solicit or encourage to leave
the employment of Seller or any of its Affiliates, any employee of Seller or any
of its Affiliates or hire any such employee who has left the employment of
Seller or any of its Affiliates within one (1) year of the termination of such
employee's employment with Seller or any of its Affiliates; PROVIDED, HOWEVER
that this Agreement shall in no way restrict Purchaser from soliciting for
employment (and subsequently hiring) any Person through the means of an
advertisement for employment in a newspaper of general circulation or by other
similar means.

                  (e) Seller and Purchaser intend that the provisions of this
Section 5.14 be enforced to the fullest extent permissible under the Laws
applied in each jurisdiction in which enforcement is sought. If any provision of
this Section 5.14, or any part hereof, shall be held by a court of competent
jurisdiction to be invalid or unenforceable, this Section 5.14 shall be amended
to revise the scope of such provision, to make it enforceable to the fullest
extent permitted by applicable Law, if possible, or to delete such provision or
such part, such revision or deletion to apply only with respect to the operation
of this Section 5.14 in the jurisdiction of such court.

            Section 5.15 EXPENSES AND APPORTIONED OBLIGATIONS.

                  (a) Except as otherwise provided in this Agreement, each party
shall bear its own expenses in connection with the preparation, execution and
performance of this Agreement and transactions contemplated hereby, including
costs of

<Page>
                                                                              45


their respective attorneys, accountants, investment bankers, brokers and other
representatives; PROVIDED, HOWEVER, that Seller is responsible for all excise,
sales, use, registration, stamp, recording, documentary, conveyancing,
franchise, property, transfer, gains and similar Taxes and fees (including,
without limitation, penalties and interest), levies and charges incurred in
connection with this Agreement and the other Transaction Documents and the
transactions contemplated hereby and thereby (collectively, "TRANSFER TAXES").

                  (b) All real estate and personal property Taxes or other
charges against, or payable by the owner of, any of the Acquired Assets relating
to a time period beginning prior to, and ending after, the Closing shall be
prorated (based on the most recent available Tax statement, latest Tax valuation
and latest bills) as of the Closing. If the Closing occurs before the Tax rate
is fixed for the then current fiscal or calendar year, whichever is applicable,
the proration of the corresponding Taxes shall be on the basis of the Tax rate
for the last preceding year applied to the latest assessed valuation. Seller's
estimated accrued liability (to the Closing) for any of the above-described
Taxes and charges that are due and payable after the Closing, to the extent
practicable, shall be made as a credit against the amount payable at the Closing
by Purchaser in accordance with Section 2.6. As to those prorations of Taxes and
other charges which are not capable of being ascertained on or prior to the
Closing Date, such prorations shall be payable by Seller to Purchaser as an
adjustment to the Purchase Price within ninety (90) days of the Closing Date.

            Section 5.16 BULK SALES COMPLIANCE. Each of Purchaser and Seller
shall waive compliance with the provisions of the applicable statutes relating
to bulk transfers or bulk sales. Seller agrees to indemnify and hold Purchaser
harmless from and against any and all claims of Seller's creditors or others
asserted against Purchaser resulting from such non-compliance as provided in
Section 9.1 hereof.

            Section 5.17 PUBLIC ANNOUNCEMENTS. Prior to the Closing, neither
Purchaser nor Seller shall issue any report, statement or press release or
otherwise make any public statement with respect to this Agreement or the other
Transaction Documents and the transactions contemplated hereby and thereby
without consulting with the other party hereto prior to taking any such action,
except as may be required by Law or may be necessary in order to discharge its
disclosure obligations, in which case such party nevertheless shall advise the
other party and discuss the contents of the disclosure before issuing any such
report, statement or press release.

            Section 5.18 ACCOUNTS RECEIVABLE. After the Closing, Purchaser shall
use reasonable efforts to collect all Accounts Receivable that were transferred
by Seller to Purchaser pursuant to Section 2.1(h). Purchaser shall not have any
obligation to seek the collection of Accounts Receivable beyond its normal
collection procedures, and shall in no event be obligated to commence
litigation. With respect to each of the Accounts Receivable that has been billed
as of the Closing Date, between the ninetieth (90th) day and the one hundred
twentieth (120th) day after the Closing Date, Seller shall have the right to use
its normal collection procedures to assist Purchaser in collecting any remaining
uncollected Accounts Receivable, provided that Seller shall, in no event, be

                                                                              46


entitled to commence any litigation. With respect to each of the Accounts
Receivable that has not been billed as of the Closing Date, between the
ninetieth (90th) day and the one hundred twentieth (120th) day after the billing
date of each such Account Receivable, Seller shall have the right to use its
normal collection procedures to assist Purchaser in collecting any remaining
uncollected Accounts Receivable, provided that Seller shall, in no event, be
entitled to commence any litigation. Any billed Accounts Receivable (or portion
thereof) which remain uncollected at the end of the one hundred twenty (120) day
period following the Closing Date or, for unbilled Accounts Receivable, at the
end of the one hundred twenty (120) day period following the actual billing
date, shall be deemed to be "UNCOLLECTED RECEIVABLES," and Seller shall be
liable to Purchaser for the aggregate amount of any such Uncollected Receivables
in accordance with Section 9.3(e). At Seller's reasonable request, during the
period following the Closing Date through and including the one hundred
twentieth (120th) day following the actual billing date of Accounts Receivable
unbilled as of the Closing Date, Purchaser shall furnish to Seller a list of
Accounts Receivable collected since the Closing Date and shall consult with
Seller regarding collection activities with respect to Uncollected Receivables.

            Section 5.19 EMPLOYEES.

                  (a) GENERAL.

                        (i) Effective on the Closing Date, Purchaser shall offer
to hire the employees of the Business (excluding individuals who are listed on
SCHEDULE 5.19(a)(i) or who are on short- or long-term disability, but subject to
Purchaser's affirmative obligation to offer employment to such individuals if
they are released to return to active employment within ninety (90) days after
the Closing Date), at a comparable job with a benefits package as set forth in
Section 5.19(b)(ii), and at a base salary or base rate of pay (excluding
commission or other incentive pay structure) not less than such employee's base
salary or base hourly rate of pay immediately prior to the Closing Date.
Effective on the Closing Date, Purchaser shall also offer to continue to employ
as temporary workers all full-time, part-time and on-call temporary workers, if
any, and shall also offer to continue to employ as consultants all full-time and
part-time consultants employed in connection with the Business immediately prior
to the Closing Date, if any. Also notwithstanding anything in this subsection
(a) to the contrary, Purchaser's obligation to offer to hire any individual who
is on short- or long-term disability on the Closing Date (i.e., such individual
is listed on SCHEDULE 5.19(a)(i)) shall not accrue unless and until such
employee is released to return to active employment within ninety (90) days
after the Closing Date.

                        (ii) Purchaser agrees to assume all employment-related
obligations with respect to the Business Employees, which obligations arise or
accrue on and after the Closing Date. For purposes of this Agreement,
"EMPLOYMENT-RELATED OBLIGATIONS" means compensation for services performed for
Purchaser on and after the Closing Date (and related employment and withholding
taxes), benefits accrued under any Purchaser-sponsored employee welfare or
pension benefit plan (as defined under ERISA Sections 3(l) and 3(2),
respectively) covering the Business Employees after the Closing Date, benefits
accrued under any other employee benefit plan or arrangement of

                                                                              47


Purchaser covering the Business Employees on and after the Closing Date and
workers' compensation benefits with respect to claims related to injuries or
illnesses with a date of injury, as determined through the applicable workers'
compensation system Laws, which is on or after the Closing Date.

                        (iii) SCHEDULE 5.19(a)(iii) sets forth a true and
correct list of the respective job titles, continuous service dates and hourly
rates or base salary, as appropriate, of the employees of the Business as of ten
(10) days prior to the Closing Date. Purchaser may rely on SCHEDULE 5.19(a)(iii)
for purposes of determining job titles, Past Service (as defined in Section
5.19(b)(i)), hourly rates and base salaries with respect to Business Employees.

                        (iv) SCHEDULE 5.19(a)(iv) sets forth a true and correct
list of the respective job positions, departments, hourly rates, third-party
employers and third-party employer hourly rates of the full-time, part-time and
on-call temporary workers as of ten (10) days prior to the Closing Date.

                        (v) SCHEDULE 5.19(a)(v) sets forth a true and correct
list of the daily or hourly rates, as applicable, and effective dates and
expiration dates of the respective written agreements of the full-time and
part-time consultants providing services to the Business pursuant to a written
agreement as of ten (10) days prior to the Closing Date.

                        (vi) Seller shall be responsible for the health care
claims of any former employees employed in connection with the Business who, as
of the Closing Date, are receiving continuation of health care coverage as
required by COBRA under affected Seller Welfare Plans. Seller shall be
responsible for providing health care continuation coverage as required by COBRA
to any Non-Hired Employees. Purchaser shall be responsible for providing health
care continuation coverage as required by COBRA to any Business Employee
terminated by Purchaser on or after the Closing Date.

                        (vii) Purchaser understands and acknowledges that Seller
is relying on Purchaser's agreement to hire all of the employees of the Business
as of the Closing Date, except as provided in Section 5.19(a)(i). In that
regard, Purchaser retains sole responsibility for any obligations or liabilities
to such employees of the Business under the WARN Act arising out of Purchaser's
failure to meet its obligations under Section 5.19(a)(i) and agrees to hold
Seller harmless for same. Purchaser's indemnification of Seller in this regard
specifically includes, but is not limited to, any claim by such employees of the
Business for back pay, front pay, benefits, or compensatory or punitive damages,
any claim by any Governmental Body for penalties regarding any issue of prior
notification (or any lack thereof) of any office closing or mass layoff, as well
as Seller's defense costs, including attorneys' fees, in defending any such
claims.

                        (viii) SCHEDULE 5.19(a)(viii) sets forth a true and
correct list of all employees of Seller who have terminated employment as of
ninety (90) days prior to the execution of this Agreement along with a
description of the reason for such

<Page>
                                                                              48


termination of employment. Seller agrees to update this list immediately prior
to Closing to reflect any additional terminations.

                  (b) EMPLOYEE BENEFITS.

                        (i) Business Employees will receive credit for Past
Service in determining general leave entitlement under Purchaser's general leave
policy. "PAST SERVICE" means service with regard to the Business (A) as an
employee of Seller or Seller's Affiliate and (B) as an employee of predecessor
companies prior to the acquisition of the Business by Seller, if any, but only
to the extent that such service is recognized by Seller for similar purposes
immediately prior to the Closing. To the extent that any Business Employee has
"earned but unused" vacation accrued as of the Closing Date, Seller shall pay
each such Business Employee either immediately prior to the Closing Date or
subsequent to the Closing Date on or before July 31, 2001, a cash amount
equivalent to such "earned but unused" vacation. For purposes of this subsection
(b)(i), "EARNED BUT UNUSED" vacation shall mean vacation earned by a Business
Employee under Seller's vacation policy, but not yet taken by such Business
Employee, determined as of the Closing Date.

                        (ii) Business Employees shall be eligible for
participation in health coverage, insurance, vacation, retirement, and other
benefit arrangements or benefit plans of Purchaser on the same basis as
similarly-situated employees of Purchaser. Purchaser will offer an open
enrollment period through the end of July 2001 to all Business Employees for the
purpose of allowing Business Employees to select health care coverage. As part
of this enrollment period, Purchaser agrees to offer Business Employees at least
one (1) health Plan, which may be chosen by Purchaser in its discretion.
Purchaser shall give credit for Past Service for purposes of (i) participation
in and eligibility for benefits under the above-referenced plans or
arrangements, (ii) determining the amount and duration of any short- or
long-term disability or severance benefits due (if severance benefits are made
available by Purchaser), and (iii) determining vesting (including, without
limitation, eligibility for early retirement, disability, and benefit options
and forms) under any retirement plans of Purchaser covering the Business
Employees. Business Employees will also receive credit toward any deductible
under Purchaser's medical plans for expenses incurred under Seller's
corresponding plans during the calendar year in which the Closing occurs.

                        (iii) Purchaser assumes no obligations under medical and
other welfare benefit plans as defined in Section 3(l) of ERISA covering any
Business Employee or Non-Hired Employee prior to the Closing Date ("SELLER
WELFARE PLANS"). Subject to the provisions of this Section 5.19, Business
Employees shall be eligible to participate in Purchaser's medical and other
welfare plans, as defined in Section 3(1) of ERISA ("PURCHASER WELFARE PLANS"),
in accordance with the terms of such plans; provided that Purchaser has no
obligation to provide benefit coverage under Purchaser's Welfare Plans to any
employee receiving short- or long-term disability benefits under the Seller
Welfare Plans as of the Closing Date to the extent such employee has not been
released to return to active employment within ninety (90) days after the
Closing Date and continues to be eligible, by reason of disability, under the

<Page>
                                                                              49


Seller Welfare Plans. Purchaser shall take reasonable actions to waive any
pre-existing condition restrictions under the Purchaser Welfare Plans with
respect to Business Employees or their dependents. In particular, but without
limitation, (A) claims for medical, hospital or other health care expenses
incurred by Business Employees or their dependents on and after the Closing Date
shall be covered under the Purchaser Welfare Plans, except for expenses incurred
by a Business Employee receiving short- or long-term disability benefits under
the Seller Welfare Plans as of the Closing Date to the extent such Business
Employee has not been released to return to active employment within ninety (90)
days after the Closing Date and continues to be eligible, by reason of
disability, under the Seller Welfare Plans and claims for such expenses incurred
by Business Employees or their dependents prior to the Closing Date shall be
covered under Seller's Welfare Plans and (B) claims of Business Employees or
their dependents for life insurance, accidental death and dismemberment and
disability benefits with respect to death, disability or other injury occurring
on or after the Closing Date shall be covered under Purchaser's Welfare Plans,
and claims for such benefits with respect to death, disability or other injury
occurring prior to the Closing Date shall be covered under Seller's Welfare
Plans (as applicable). The amount and type of benefits payable in any case shall
be determined in accordance with the terms of the applicable welfare plan.

                        (iv) Prior to the Closing Date, Seller shall have taken
all necessary actions to cause all accounts (including, without limitation, the
employer match portion of any such accounts) under Seller's 401(k) plan of the
Business Employees who are participants in such plan to become fully vested as
of the Closing Date.

                        (v) No assets or liabilities with respect to the
Business Employees shall be transferred as a result of this Agreement from any
retirement Plan of Seller (defined contribution and defined benefit) to any plan
maintained or established by Purchaser. Seller shall retain all obligations to
fund or otherwise provide benefits accrued on or before the Closing Date by the

required to sell, assign, convey, transfer and deliver to Purchaser, as promptly
as practicable, at Seller's sole cost and expense, any such asset, property,
license, right and agreement without the requirement of any payment therefor by
Purchaser, whereupon such asset, property, license, right or agreement shall be
deemed to be an Acquired Asset for purposes of this Agreement. Nothing in this
Section 5.23 shall be construed to limit or prejudice Purchaser's other rights
and remedies under this Agreement, including, without limitation, Purchaser's

($50,000) (the "BASKET AMOUNT"), whereupon Purchaser shall be entitled to
receive in full indemnity payments in excess of the Basket Amount; PROVIDED,
HOWEVER, that solely for purposes of determining whether the amount of Seller's
indemnification obligations exceed Fifty Thousand Dollars ($50,000) in the
aggregate, a breach of Seller's representations or warranties shall be
determined without regard to any limitation or qualification as to materiality
or Business Material Adverse Effect (or similar concepts) set forth in such
representation or warranty.

                  (b) Notwithstanding the foregoing provisions of this Section
9.5, Purchaser shall be entitled to receive any indemnification payments in
respect of the Basket Exclusions without regard to the individual or aggregate
amounts thereof and without regard to whether the aggregate of all other
indemnification payments shall have exceeded, in the aggregate, the Basket
Amount.

                  (c) The maximum amount of indemnification payments under
Section 9.1(a) (excluding those based upon, arising out of or otherwise in
respect of the Basket Exclusions), shall not exceed, in the aggregate, Five
Million Dollars ($5,000,000).

                  (d) The maximum amount of indemnification payments under
Section 9.2 with respect to any inaccuracy in or breach of a representation or
warranty shall not exceed, in the aggregate, Five Million Dollars ($5,000,000),
provided that Seller shall not be entitled to receive any indemnification
payments under Section 9.2 until the aggregate amount of all such
indemnification payments exceeds the Basket Amount, whereupon Seller shall be
entitled to receive in full indemnity payments exclusive of the Basket Amount up
to Five Million Dollars ($5,000,000).

            Section 9.6 DEFENSE OF CLAIMS. In the case of any claim for
indemnification under Section 9.1, 9.2 or 9.3 arising from a claim of a third
party, an indemnified party shall give prompt written notice to the indemnifying
party (and, if the indemnifying party is Seller, to Seller and the Escrow Agent)
of any claim, suit or demand of which such indemnified party has knowledge and
as to which it may request

<Page>
                                                                              59


indemnification hereunder. The failure to give such notice shall not, however,
relieve the indemnifying party of its indemnification obligations except to the
extent that the indemnifying party is actually harmed thereby. The indemnifying
party shall have the right to defend and to direct the defense against any such
claim, suit or demand, in its name and at its expense, and with counsel selected
by the indemnifying party unless such claim, suit or demand seeks an injunction
or other equitable relief against the indemnified party; PROVIDED, HOWEVER, the
indemnifying party shall not have the right to defend or direct the defense of
any such claim, suit or demand if it refuses to acknowledge fully its
obligations to the indemnified party or contests, in whole or in part, its
indemnification obligations therefor. If the indemnifying party elects and is
entitled to compromise or defend such claim, it shall within thirty (30) days
(or sooner, if the nature of the claim so requires) notify the indemnified party
of its intent to do so, and the indemnified party shall, at the expense of the
indemnifying party, cooperate in the defense of such claim, suit or demand. If
the indemnifying party elects not to compromise or defend such claim, fails to
notify the indemnified party of its election as herein provided or refuses to
acknowledge or contests its obligation to indemnify under this Agreement, the
indemnified party may pay, compromise or defend such claim. Except as set forth
in the immediately preceding sentence, the indemnifying party shall have no
indemnification obligations with respect to any such claim, suit or demand which
shall be settled by the indemnified party without the prior written consent of
the indemnifying party (which consent shall not be unreasonably withheld or
delayed); PROVIDED, HOWEVER, that notwithstanding the foregoing, the indemnified
party shall not be required to refrain from paying any claim which has matured
by a court judgment or decree, unless an appeal is duly taken therefrom and
exercise thereof has been stayed, nor shall it be required to refrain from
paying any claim where the delay in paying such claim would result in the
foreclosure of a lien upon any of the property or assets then held by the
indemnified party or where any delay in payment would cause the indemnified
party material economic loss. The indemnifying party's right to direct the
defense shall include the right to compromise or enter into an agreement
settling any claim by a third party; provided that no such compromise or
settlement shall obligate the indemnified party to agree to any settlement which
requires the taking of any action by the indemnified party other than the
delivery of a release. Notwithstanding the indemnifying party's right to
compromise or settle in accordance with the immediately preceding sentence, the
indemnifying party may not settle or compromise any claim over the objection of
the other; PROVIDED, HOWEVER, that consent to settlement or compromise shall not
be unreasonably withheld or delayed. The indemnified party shall have the right
to participate in the defense of any claim, suit or demand with counsel selected
by it subject to the indemnifying party's right to direct the defense. The fees
and disbursements of such counsel shall be at the expense of the indemnified
party; PROVIDED, HOWEVER, that, in the case of any claim, suit or demand which
seeks injunctive or other equitable relief against the indemnified party as to
which the indemnifying party shall not in fact have employed counsel to assume
the defense of such claim, suit or demand, the fees and disbursements of such
counsel shall be at the expense of the indemnifying party.

            Section 9.7 NON-THIRD PARTY CLAIMS. Any claim which does not result
in a third party claim shall be asserted by a written notice to the other party
or parties. The recipient of such notice shall have a period of thirty (30) days
after receipt of such notice

<Page>
                                                                              60


within which to respond thereto. If the recipient does not respond within such
thirty (30) days, the recipient shall be deemed to have accepted responsibility
for the Losses set forth in such notice and shall have no further right to
contest the validity of such notice. If the recipient responds within such
thirty (30) days after the receipt of the notice and rejects such claim in whole
or in part, the party delivering shall be free to pursue such remedies as may be
available to it under contract or applicable law.

            Section 9.8 CLAIMS AGAINST THE ESCROW AGENT. Any indemnification
obligations of Seller shall be satisfied from any amounts held by the Escrow
Agent pursuant to the Escrow Agreement prior to Purchaser exercising any other
remedy, offset or action (other than (i) any action seeking equitable remedies,
(ii) in the case of fraud, (iii) if and to the extent the amounts, if any, then
held by the Escrow Agent are insufficient to satisfy such indemnification
obligations and (iv) any action seeking to enforce Purchaser's rights under
Section 5.23) to seek recovery of amounts payable pursuant to Seller's
obligations under this Article IX.

            Section 9.9 SUBROGATION. Upon making an indemnity payment pursuant
to this Agreement, the indemnifying party will, to the extent of such payment,
be subrogated to all rights of the indemnified party against any third party in
respect of the damages to which the payment related. Without limiting the
generality of any other provision hereof, the indemnified party and indemnifying
party will duly execute upon request all instruments reasonably necessary to
evidence and perfect the above described subrogation rights.

            Section 9.10 EXCLUSIVE REMEDIES. The remedies provided for in this
Agreement shall be the sole and exclusive remedies of the parties and their
respective officers, directors, employees, Affiliates, successors and assigns
for any breach of or inaccuracy in any representation or warranty contained in
this Agreement or any certificate delivered at Closing; PROVIDED, HOWEVER, that
nothing herein is intended to waive any claims for fraud or waive any equitable
remedies to which a party may be entitled.

            Section 9.11 NO DOUBLE RECOVERY; USE OF INSURANCE. No party shall be
entitled to indemnification or reimbursement under any provision of this
Agreement for any amount to the extent such party or its Affiliate has been
indemnified or reimbursed for such amount under any other provision of this
Agreement or the Schedules attached hereto, or any document executed in
connection with this Agreement. Furthermore, in the event any damages related to
a claim by an indemnified party are covered by insurance, the indemnified party
may seek recovery under such insurance, in which case the indemnified party
shall not be entitled to recover from the indemnifying party (and shall refund
amounts received up to the amount of indemnification actually received) with
respect to such damages to the extent, and only to the extent, the indemnified
party recovers the insurance payment specified in the policy. Notwithstanding
the foregoing, if any provision of this Section 9.11 eliminates or in any way
diminishes the right of an indemnified party to recover a claim covered by
insurance or otherwise, this Section 9.11 shall have no further force and effect
with respect to such claim.

            Section 9.12 TREATMENT OF INDEMNITY PAYMENTS BETWEEN THE PARTIES.
Unless otherwise required by applicable Law, all indemnification payments shall
constitute adjustments to the Purchase Price for all Tax purposes, and no party
shall take any position inconsistent with such characterization.

limitation, any related broker's or finder's fee.

            Section 10.3 WAIVERS AND AMENDMENTS; NON-CONTRACTUAL REMEDIES;
PRESERVATION OF REMEDIES. This Agreement may be amended, superseded, canceled,
renewed or extended, and the terms hereof may be waived, only by a written
instrument signed by Purchaser and Seller or, in the case of a waiver, by or on
behalf of the party waiving compliance. No delay on the part of any party in
exercising any right, power or privilege hereunder shall operate as a waiver
thereof. Nor shall any waiver on the part of any party of any such right, power
or privilege, nor any single or partial exercise of any such right, power or
privilege, preclude any further exercise thereof or the exercise of any other
such right, power or privilege. The rights and remedies herein provided are
cumulative and are not exclusive of any rights or remedies that any party may
otherwise have at law or in equity. The rights and remedies of any party based
upon, arising out of or otherwise in respect of any inaccuracy in or breach of
any representation, warranty, covenant or agreement contained in this Agreement
or any document delivered pursuant to this Agreement shall in no way be limited
by the fact that the act, omission, occurrence or other state of facts upon
which any claim of any such inaccuracy or breach is based may also be the
subject matter of any other representation, warranty, covenant or agreement
contained in this Agreement or any document delivered pursuant to this Agreement
(or in any other agreement between the parties) as to which there is no
inaccuracy or breach.

            Section 10.4 PUBLIC DISCLOSURE. Each of the parties to this
Agreement hereby agrees with the other party that, except as may be required to
comply with the requirements of applicable Law, no press release or similar
public announcement or communication will be made or caused to be made
concerning the execution or performance of this Agreement or the transactions
contemplated hereunder unless specifically approved in advance by both parties,
such approval not to be unreasonably withheld, conditioned or delayed. If any

such announcement such party will deliver a draft of
