                        CONVERSION OF SECURITIES FOR CASH

             2.1 Purchase Price. The Parent agrees to pay or cause to be paid,
an aggregate consideration of (a) Thirty-Seven Million Dollars ($37,000,000)
(the "AGGREGATE CONSIDERATION"), plus (b) any amounts payable under Sections
2.3(b) and (c), plus (c) any sum or sums due hereunder pursuant to Section 2.8,
subject to any right of set-off the Parent may have pursuant to Section 8.8 (the
"CONTINGENT CONSIDERATION") (the Aggregate Consideration and the Contingent
Consideration being hereinafter referred to collectively as the "PURCHASE
PRICE"), in order to acquire all of the shares of Common Stock outstanding at
the Effective Time and to cause the rights of Option Holders (as defined in
Section 2.4) to acquire Common Stock to be extinguished as of the Effective
Time. The parties will accomplish the foregoing by means of the Merger and the
amount, timing, and form of consideration to be payable to the Shareholders and
Option Holders and the manner of payment is set forth in this Article II.

             2.2 Price Per Share. Each share of Common Stock issued and
outstanding immediately prior to the Effective Time shall, by virtue of the
Merger and without any action on the part of the holder thereof, be converted
into the right to receive, at the times and subject to the other provisions of
this Agreement, a per share amount (the "PER SHARE AMOUNT") equal to the sum of
(1) the quotient obtained by dividing (a) the sum of (i) the Purchase Price
multiplied by a fraction the numerator of which is the number of shares of
Common Stock issued and outstanding immediately prior to the Effective Time
("N") and the denominator of which is the

                                                                               6


sum of N PLUS the aggregate number of shares of Common Stock covered by Options
(as defined in Section 2.4) outstanding immediately prior to the Effective Time
("S"), PLUS (ii) the aggregate exercise price of the Options outstanding
immediately prior to the Effective Time ("EP"), by (b) N, PLUS (2) the amounts
payable under Sections 2.3 (b) and (c). Schedule 2.2 sets forth for illustration
an example of the calculations contemplated by Sections 2.2, 2.3 and 2.4.

             2.3 Payment. The Per Share Amount shall be paid as follows:

                  (a) Three days subsequent to the Effective Time, the Parent
shall pay or cause the Surviving Corporation to pay to each Shareholder entitled
to receive a payment under Section 2.2 an amount for each share of Common Stock
held at the Effective Time (the "PER SHARE CLOSING AMOUNT") equal to the
quotient obtained by dividing (a) the sum of (i) Twenty-seven Million Dollars
($27,000,000) multiplied by a fraction the numerator of which is N and the
denominator of which is the sum of N plus S, PLUS (ii) EP multiplied by the
fraction obtained by dividing 27 by 37, by (b) N.

                  (b) On December 15, 1998, for each share of Common Stock held
by such Shareholder, the Parent shall pay or cause the Surviving Corporation to
pay to each Shareholder entitled to receive a payment under Section 2.2 the
quotient of One Million Dollars ($1,000,000) divided by N, as partial
reimbursement of the estimated Deferred Tax Liability (as defined in Section
9.1) .

                  (c) On April 1, 1999, the Parent shall pay or cause the
Surviving Corporation to pay to each Shareholder entitled to receive a payment
under Section 2.2, the quotient of Three Million Dollars ($3,000,000) divided by
N for each
<PAGE>

                                                                               7


share of Common Stock held by such Shareholder, as partial reimbursement of the
estimated Deferred Tax Liability.

                  (d) At the Closing, the Parent shall deliver to each
Shareholder entitled to receive a payment under Section 2.2, a subordinated
promissory note due May 31, 2000 (the "NOTES"), in substantially the form of
Exhibit II, in principal amount equal to the quotient obtained by dividing (a)
the sum of (i) Ten Million Dollars ($10,000,000) multiplied by a fraction the
numerator of which is N and the denominator of which is the sum of N plus S,

for each share of Common Stock held by such Shareholder at the Effective Time.

                  (e) The Contingent Consideration to be paid pursuant to this
Agreement, if any, shall be paid by the Parent in accordance with the terms of
Section 2.8, subject to any set-off right the Parent may have pursuant to
Section 8.8.

with the Company in the form of Exhibit III providing that each holder of an
Option outstanding immediately prior to the Effective Time, whether or not then
exercisable, shall be entitled to receive in full settlement and cancellation of
such Option, and in return for a waiver of all rights associated with such
Option under the terms of any of the Company's option plans, the following
consideration at the following times:

                  (a) At the Closing, the Parent shall pay or cause the Merger

                                                                               8


in cash for each Option held equal to the remainder of (i) Twenty-seven Million
Dollars ($27,000,000) MULTIPLIED by a fraction the numerator of which is the
number of shares of Common Stock covered by such Option ("OS") and the
denominator of which is the sum of N plus S, MINUS (ii) the exercise price of
such Option ("OEP") MULTIPLIED by OS MULTIPLIED by the fraction obtained by
dividing 27 by 37.

                  (b) At the Closing, the Parent shall deliver to the Company

in principal amount for each Option held equal to the remainder of (i) Ten
Million Dollars ($10,000,000) MULTIPLIED by a fraction the numerator of which is
OS and the denominator of which is the sum of N plus S, MINUS (ii) OEP
MULTIPLIED by OS MULTIPLIED by the fraction obtained by dividing 10 by 37.

                  (c) The Contingent Consideration to be paid pursuant to this
Agreement, if any, shall be paid by the Parent in accordance with the terms of
Section 2.8, subject to any set-off right the Parent may have pursuant to
Section 8.8.

                  If any Option Holder shall fail to enter into an agreement
referred to in the first paragraph of this Section 2.4, then the Company shall
promptly exercise all its rights and give all required notice under its option
plans so that the Option will be accelerated, vested and converted at the
Effective Time into the consideration provided for in this Section 2.4, and the
Closing Date and any termination rights under this Agreement will be tolled for
a reasonable period not to exceed 45 days to permit the Company to take such
actions.

             2.5 Merger Sub Common Stock. Each share of common stock of the
Merger Sub issued and outstanding immediately prior to the Effective Time shall,
<PAGE>

                                                                               9


by virtue of the Merger and without any action on the part of the holder
thereof, be converted into one share of common stock of the Surviving
Corporation.

             2.6 Exchange of Common Stock and Option Payments.

                  (a) Not later than three Business Days prior to the Closing,
the Company shall mail to each Shareholder and to each Option Holder a notice
and, as applicable, a transmittal form and/or an option cancellation and
settlement form (in form and substance reasonably satisfactory to the Parent)
advising such Shareholder and Option Holder of the procedure for delivering
certificates to the Company and effecting payments for Options in accordance
with Sections 2.3 and 2.4. At the Closing, the Company shall deliver to the
Merger Sub all of the certificates that the Company shall have theretofore
received, together with duly executed transmittal forms and option cancellation
and settlement forms received by the Company from the Shareholders and Option
Holders.

                  Thereafter, each holder of a certificate representing a share
of Common Stock not delivered to the Merger Sub, may surrender to the Surviving
Corporation such certificate together with an executed transmittal form, and
receive from the Surviving Corporation in exchange therefor the payment or
payments called for under Section 2.3, and each Option Holder may deliver an
option cancellation and settlement form and receive from the Surviving
Corporation in exchange therefor the amount payable under Section 2.4, in each
case without interest. Upon surrender of any such certificates, such
certificates shall be canceled. The Surviving Corporation may set off any amount
owed by a Shareholder or Option Holder to the Company or
<PAGE>

                                                                              10


any of the Subsidiaries immediately prior to the Effective Time against any
payment due under this Agreement.

                  (b) If the consideration payable for any share of Common Stock
is to be delivered to a person other than the person in whose name the
certificate representing such shares is registered, it shall be a condition of
such delivery that the certificate so surrendered shall be properly endorsed or
accompanied by appropriate stock powers, in either case signed as the name of
the record holder appears on such certificate, and shall otherwise be in proper
form for transfer, and that the person requesting such delivery shall pay to the
Surviving Corporation any transfer or other taxes required by law as a result of
such delivery to a person other than the record holder of the certificate
surrendered, or shall establish to the Surviving Corporation's satisfaction that
such tax has been paid or is not payable.

                  (c) Any amounts remaining unclaimed by holders of shares of
Common Stock immediately prior to such time as such amounts would otherwise
escheat to or become property of any governmental entity shall, to the extent
permitted by applicable law, become the property of the Surviving Corporation
free and clear of any claims or interest of any Person previously entitled
thereto.

                  (d) Each Shareholder shall cease at the Effective Time to have
any rights as a Shareholder of the Company or the Surviving Corporation (other
than rights to receive the payments provided for in Section 2.3) and each Option
Holder shall cease to have any rights under the Option Plan or the option
agreements pursuant to which it acquired its Options (other than to receive the
payments provided

shall thereafter be made on the stock transfer books of the Surviving
Corporation.

             2.7 Withholding: Net Payments. Notwithstanding anything in this
Agreement to the contrary, any amount paid pursuant to this Agreement or the
Notes to Option Holders, including without limitation the payments to Option
Holders under Section 2.4, or to Shareholders that are not United States
Persons, as defined in Section 7701(a)(30) of the Code (as defined below in
Section 3.1(M)(ii)), shall be net of all applicable federal, state and local
withholding taxes, as determined by the Surviving Corporation and agreed to by
the Sellers' Representative. The Surviving Corporation shall withhold and remit
to the appropriate taxing authority all such withholding taxes due in connection
with the payments made by it, and such remittance shall be deemed a payment of
amounts owed to any person entitled to payment pursuant to this Agreement. Any
payment to non-employee Option Holders shall be at the minimum withholding
amount required by applicable law. Prior to the Effective Time, the Company
shall use its reasonable efforts to take such actions as shall be necessary to
allow for compliance with this Section 2.7.

             2.8 Determination and Payment of Contingent Consideration.

                  (a) The Parent shall, at its sole cost and expense, cause the
Accountant to deliver to the Parent and the Sellers' Representative not later
than September 30, 1999, a statement of Operating Profit (as defined in Section
9.1) for the Company for the fiscal year 1999 (July 1, 1998 - June 30, 1999) in
accordance with GAAP applied on a consistent basis (the "STATEMENT OF OPERATING
PROFIT"). Notwithstanding the foregoing, the Parent may elect to modify the
Company's actual
<PAGE>

                                                                              12


financial reporting to conform to a calendar year basis consistent with the
Parent's fiscal year, in which event the Parent shall cause the Statement of
Operating Profit to be delivered by April 1, 2000, and shall pay interest at the
rate of six percent per annum commencing September 30, 1999, increasing to seven
and one-half percent per annum commencing April 1, 2000, on the amount of any
Contingent Consideration subsequently determined to have been earned in
accordance with this Section 2.8; PROVIDED, HOWEVER, that the Parent shall
nevertheless continue to separately track, through its automated financial
reporting system, the performance of contracts comprising the Company's business
as if the Company had continued to operate on a June 30, 1999 fiscal year basis.
Concurrent with the delivery of the Statement of Operating Profit, the
Accountant shall certify to the Parent that the Statement of Operating Profit
was calculated in accordance with the provisions of this Agreement (and the
Parent shall use its reasonable efforts to cause the Accountant to allow access
to the Accountant's workpapers prepared in connection with the Statement of
Operating Profit to the Sellers' Representative in order to assist the Sellers'
Representative to determine whether the Statement of Operating Profit was
calculated in accordance with the provisions of this Agreement, if the Sellers'
Representative executes and delivers on behalf of himself and the Sellers the
Accountant's customary agreement for indemnification and release of liability
(an "INDEMNIFICATION AGREEMENT") in a form acceptable to the Accountant).

                  (b) The Sellers' Representative and his agents shall have
reasonable access to all personnel of the Company and shall have the right to
review all books, accounting records and other materials of the Company and the
Subsidiaries
<PAGE>

                                                                              13


relevant to the preparation of the Statement of Operating Profit that the
Sellers' Representative or his agents may reasonably request. In addition, the
Parent shall use its reasonable efforts to cause the Sellers' Representative and
his agents, after execution and delivery by the Seller's Representative and such
agents of the Indemnification Agreement with respect to the Statement of
Operating Profit, to have reasonable access to all personnel of the Accountant
involved in the preparation of the Statement of Operating Profit and to be
permitted to review the Accountant's audit work papers with respect thereto. In
the event that the Parent and/or the Sellers' Representative disagree(s) in any
respect with the Statement of Operating Profit, the Sellers' Representative
and/or the Parent shall deliver to the other, within twenty-one (21) days after
delivery by the Accountant of such Statement of Operating Profit, a written
notice (an "OBJECTION NOTICE") specifying the matters to which it objects and
the basis for such disagreement (together with any authority or documentation
supporting its position). Any Objection Notice may include disagreements with
respect to any adjustments in the calculation of Operating Profit made pursuant
to Section 4.19(A) of this Agreement, such disagreement to be resolved in
accordance with the methodology provided in this Section 2.8 of this Agreement.
The Parent and the Sellers' Representative shall thereupon endeavor in good
faith to resolve any disagreement or dispute arising out of the Objection
Notice. In the event such parties do so, such parties shall promptly execute a
document which sets forth the resolution of such disagreement or dispute.

                  (c) In the event that the Parent or the Sellers'
Representative timely receives an Objection Notice and the Sellers'
Representative and the Parent are

                                                                              14


unable to resolve the disagreement specified in the Objection Notice within ten
(10) Business Days after receipt of the Objection Notice, the disagreement shall
be submitted to a nationally recognized firm of independent public accountants
(other than the Accountant) chosen by the Parent and the Sellers' Representative
(the "CONTINGENCY ACCOUNTANT"); PROVIDED that if the Parent and the Sellers'
Representative are unable to agree on such accountants within fourteen (14) days
following the end of such ten (10) Business Day period, then the Parent and the
Sellers' Representative will within seven (7) days following the end of such
fourteen (14) day period jointly request that the president of the American
Arbitration Association (the "AAA") select an accountant, such accountant to be
associated with a nationally recognized accounting firm other than the
Accountant (such AAA-appointed accountant to be deemed the "CONTINGENCY
ACCOUNTANT" for purposes of this Agreement). Upon delivery to the Parent and the
Sellers' Representative of a statement in writing setting forth the conclusion
of the Contingency Accountant's opinion of the disputed item or items and the
effect of such conclusion on the Statement of Operating Profit, such
determination shall be final and binding upon the Parent and the Sellers without
any further right of appeal.

                  (d) The Contingency Accountant shall have reasonable access to
all personnel of the Company and shall have the right to review all books,
accounting records and other materials pertaining to the Statement of Operating
Profit that the Contingency Accountant shall request. The Contingency Accountant
shall render its determination on the disagreement submitted to it within sixty
(60) days of submission of the disagreement by the Parent and the Sellers'
Representative. The

Statement of Operating Profit will be deemed to be final, binding and not
subject to appeal (the "FINAL STATEMENT OF OPERATING PROFIT"), on and as of the
first to occur of the following: (i) the expiration of the twenty-one (21) day
period referred to in Section 2.8(b) without the delivery of an Objection Notice
respecting the Statement of Operating Profit; (ii) the execution of a document
pursuant to Section 2.8(b), setting forth the resolution of any dispute
described in any Objection Notice respecting the Statement of Operating Profit,
by the Sellers' Representative and the Parent; and (iii) the date that the
Contingency Accountant delivers the relevant determination to the Parent and the
Sellers' Representative pursuant to Section 2.8(c), it being understood that the
Final Statement of Operating Profit shall mean a Statement of Operating Profit
as modified by any such resolution or determination.

                  (e) Payment of Contingent Consideration. The Shareholders and
the Option Holders shall be entitled to receive $3.75 million of aggregate
Contingent Consideration if the Company's Operating Profit as set forth on the
Final Statement of Operating Profit (the "FINAL OPERATING PROFIT") is $5.4
million or greater, but less than $5.7 million. Alternatively, the Shareholders
and the Option Holders shall be entitled to receive $4.375 million of aggregate
Contingent Consideration if the Company's Final Operating Profit is $5.7 million
or greater, but less than $6.0 million. Alternatively, the Shareholders and the
Option Holders shall be entitled to receive $5.0 million if the Company's Final
Operating Profit is $6.0 million or greater, but less than $6.6 million.
Alternatively, the Shareholders and the Option Holders shall be entitled to
receive $5.625 million of aggregate Contingent Consideration if the Company's
Final Operating Profit is $6.6 million or greater, but

less than $7.2 million. Alternatively, the Shareholders and the Option Holders
shall be entitled to receive $6.25 million of aggregate Contingent Consideration
if the Company's Final Operating Profit is $7.2 million or greater. The Parent
shall pay or cause to be paid to each Shareholder and the Parent shall pay or
cause the Surviving Corporation to pay to each Option Holder the aggregate
Contingent Consideration payable hereunder divided by the sum of N plus S for
each share of Common Stock held or covered by Options held by such Person at the
Effective Time. Any payment required to be made under this Section 2.8 shall be
made not later than the tenth (10th) Business Day after the Statement of
Operating Profit is deemed to be the Final Statement of Operating Profit.

                  (f) Fees and expenses, if any, of the Contingency Accountant
with respect to the Statement of Operating Profit shall be paid by the Company,
except that such fees and expenses shall be paid by the Shareholders and Option
Holders pro rata by number of shares of Common Stock owned or covered by Options
held at the Effective Time if the Sellers' Representative delivers an Objection
Notice with respect to the Statement of Operating Profit which does not result
in an increase in the Contingent Consideration payable under this Agreement.

3.1(T) each Seller is

the Company represents and warrants (except as to the matters set forth in
Sections 3.1(B)(i), 3.1(B)(iii), 3.1(D) and 3.1(K)(i), as to which no

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 assets and to carry
on its business as now being or heretofore conducted. The Company 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 its business requires such qualification, except where the failure to
be so qualified would not have a Company Material Adverse Effect (as defined
below). "COMPANY 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 condition (financial or otherwise), properties,
assets, liabilities, business, operations, results of operations, or reasonably
anticipated prospects of the Company and its Subsidiaries taken as a whole. The
copies of the Certificates of Incorporation and By-Laws (or comparable
instruments) of the Company and each of the Subsidiaries previously delivered to
the Parent or its counsel, in each case as amended, are complete and correct.

the Company directly or indirectly owns or has the power to vote capital stock
or other ownership interests. The Company does not directly or indirectly own
any interest in any other person or entity. Each of the Subsidiaries is an
entity duly organized, validly existing and in good standing under the laws of
its jurisdiction of organization and has all requisite power and authority to
own, lease and operate its properties and assets and to carry on its business as
now being and as heretofore conducted. The respective minute books, or
comparable records, of the Company and each of the Subsidiaries contain true and
complete records of all meetings and consents in lieu of meetings of their
Boards of Directors or similar governing bodies (and any committees thereof) and
of their stockholders (or partners or members) since the times of their
respective incorporation or formation, and accurately reflect 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 the Company and
each of the Subsidiaries are true and complete.

                  (B) Authority to Execute and Perform Agreement.

                        (i) Each Seller has all requisite power and all
authority and approvals required to enter into, execute and deliver this
Agreement and each and every agreement and instrument contemplated hereby to
which it is or will be a party (and, if applicable, a Non-Compete and

hereunder and thereunder. This Agreement has been duly executed and delivered by
each Seller, and on the Closing Date, each and every agreement and instrument

Assuming due execution and delivery hereof and thereof by the Parent, this
Agreement and each such other agreement and instrument will be valid and binding
obligations of such Seller, enforceable against such 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.

                        (ii) The Company has full right and power and all
authority and approvals required to enter into, execute and deliver this
Agreement and each and every agreement and instrument contemplated hereby to

securities or obligations convertible into or exchangeable for, or giving any
person any right to subscribe for or acquire from the Company or any of the
Subsidiaries any shares of capital stock of the Company or any of the

any Liens all of the outstanding capital stock of the Surviving Corporation
(except for Liens that may attach by reason of the Parent's ownership thereof)
and no Option shall be outstanding.

                  (D) Vote Required. The execution and delivery of this

the Company or any of the Subsidiaries immediately after the Closing Date.

                        (vi) There is no arrangement under any Plan with
respect to any employee that would result in the payment of any amount that by
operation of Code Section 280(G) or 162(m) would not be deductible by the
Company or any of the Subsidiaries.

                        (vii) With respect to each Plan which is a "welfare
plan" (as described in ERISA Section 3(1)): (i) no such plan provides medical or

entitle any individual to severance pay, unemployment compensation or other
benefits or compensation, (ii) accelerate the time of payment or vesting, or

(iii) result in or satisfy a condition to the payment of compensation that

Company's past two fiscal years and the amount paid out under each policy with
respect to such claims. None of the Company, any of the Subsidiaries or any of

been duly executed and delivered by the Parent and the Merger Sub, and on the
Closing Date, each and every agreement and instrument contemplated hereby to
which the Parent or Merger Sub is a party on the Closing Date will be duly
executed and delivered by the Parent or Merger Sub. Assuming due execution and

there has been no change in the business, properties, assets, reasonably
anticipated prospects, operations or condition (financial or otherwise) of the
Parent or the Merger Sub which has resulted or reasonably could be expected to
result in or which the Parent or the Merger Sub has reason to believe could
reasonably be expected to result in a Parent Material Adverse Effect (as defined
below), and neither the Parent nor the Merger Sub knows of any such change that
is threatened, nor has there been any damage, destruction or loss affecting the
assets, properties, business, reasonably anticipated prospects, operations or
condition (financial or otherwise) of the Parent or the Merger Sub, whether or
not covered by insurance which has resulted or reasonably could be expected to
result in or which Parent or Merger Sub has reason to believe could reasonably
be expected to result in a Parent Material Adverse Effect. "PARENT 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
condition (financial or otherwise), properties, assets, liabilities, business,

                                                                              55


operations, results of operations, or reasonably anticipated prospects of the
Parent and the Merger Sub taken as a whole.

threatened against or involving the Parent or the Merger Sub, or any outstanding
orders, judgments, injunctions, awards or decrees of any court, governmental or
regulatory body or arbitration tribunal against or involving the Parent or the
Merger Sub which could have a Parent Material Adverse Effect.

                                   ARTICLE IV

                      ADDITIONAL AGREEMENTS OF THE PARTIES

             4.1 Taxes; Section 338(h)(10) Election.

                  (A) As the shareholders of an S corporation, the Shareholders
will pay and discharge and be responsible for any and all Taxes due or payable
by the Shareholders and by the Company for any taxable year or taxable period
ending on or before the Closing Date including, without limitation, any
liability that the Shareholders may owe as individuals in any jurisdiction in
which the Company is treated as an S corporation. In addition, the Shareholders
will pay and discharge and be responsible for any State taxes (including,
without limitation, excise and franchise taxes) due or payable by the Company
for any taxable year or taxable period ending
<PAGE>

                                                                              56


on or before the Closing Date, including, without limitation, any liability that
the Shareholders may owe as individuals in any jurisdiction in which the company
is treated as an S corporation. Any excise and franchise taxes due or payable as
a result of the Election (as hereinafter defined) shall be borne by the
Shareholders. For purposes of this Section 4.1, and as required in connection
with the Election, the current fiscal year of the Company will be treated as two
separate tax years, one beginning on January 1, 1998 and ending on the Closing
Date and the other beginning on the date after the Closing Date and ending at
the end of the 1998 fiscal year of the Company. The books and records of the
Company will be closed at the close of business on the Closing Date.

                  (B) The Parent, the Merger Sub, the Shareholders and the
Company agree to make a timely election under Section 338(h)(10) of the Code and
similar provisions of state and local law, where allowable, in respect of the
Merger (the "ELECTION"), thereby causing such Merger to be treated as a purchase
or sale of assets of the Company for federal purposes and to the extent allowed
by state, local and foreign tax laws. On all returns relating to Income Taxes,
the Shareholders and the Parent will report the transfers under this Agreement
consistent with the Election. Neither the Shareholders, the Parent nor the
Company will take a position on a return relating to Income Taxes contrary to
the Election unless required to do so by applicable state, local or foreign tax
laws or pursuant to a determination as defined in Section 1313(a) of the Code.
Each of the parties shall take any action required to effect state, local and
foreign tax law conformity with application of the Election to the extent
allowed by law.

                                                                              57


                  (C) The Parent and the Merger Sub, the Shareholders and the
Company acknowledge and agree that the Purchase Price (as defined in Section 2.1
above) reflects the fact that the Shareholders will incur substantial tax
obligations as a result of the Merger, and the tax treatment of such Merger as a
deemed sale of all of the assets of the Company; other than as defined in this
Section 4.1, the Parent and the Merger Sub shall have no further obligations and
make no further payments to the Company relating to any and all tax liabilities
incurred by the Company or the Shareholders as a result of the Merger, or the
Election, or relating to any current or deferred tax liabilities of the Company
or the Shareholders arising on or prior to the Closing Date.

                  (D) In connection with the Election, not later than 150 days
after the Closing Date, the Parent and the Sellers' Representative shall act
together in good faith to (i) determine and jointly agree upon the "MODIFIED
AGGREGATE DEEMED SALES PRICE" of the assets of the Company (within the meaning
of, and in accordance with, Treasury Regulations Section 1.338(h)(10)-1(f) or
comparable provisions for state, local and foreign law) (the "MADSP
DETERMINATION"), and (ii) determine and jointly agree upon the allocations of
the "MODIFIED AGGREGATE DEEMED SALES PRICE" in accordance with Section 338(b)(5)
of the Code and Treasury Regulations Section 1.338(b)-2T promulgated thereunder
(and comparable provisions for state, local and foreign law) (the "MADSP
ALLOCATIONS"). If the parties are unable to agree within such period, the MADSP
Determination and MADSP Allocations provided for under clauses (i) and (ii)
shall be determined within 30 days thereafter by an independent qualified
appraiser selected by the Parent and reasonably acceptable to the Seller's
<PAGE>

                                                                              58


Representative (the "APPRAISER"), the costs of which shall be borne by the
Parent. The Parent, the Sellers and the Shareholders shall (w) be bound by the
joint MADSP Determination and MADSP Allocations (whether agreed upon or
determined by the Appraiser) for purposes of determining any Taxes, (x) prepare
and file their Tax Returns on a basis consistent with such MADSP Determination
and MADSP Allocations, (y) take no position inconsistent with such MADSP
Determination and MADSP Allocations on any applicable Tax Return, in any
proceeding before any taxing authority or otherwise and (z) immediately
following the MADSP Determination and MADSP Allocations (whether agreed upon or
determined by the Appraiser), exchange completed and duly executed copies of
Internal Revenue Service Form 8023, required schedules thereto, and any similar
state, local or foreign forms computed to reflect such MADSP Determination and
MADSP Allocations (whether agreed upon or determined by the Appraiser).

             4.2 Tax Return Filing. (a) The Company and the Shareholders shall
cause the Company and each of the Subsidiaries to prepare, in a manner
consistent with past practices, and timely file (including extensions of time to
file) all Tax Returns required to be filed by the Company and each of the
Subsidiaries, the due date of which (without extensions) occurs on or before the
Closing Date and pay all Taxes due with respect to any such Tax Returns.

                  (b) The Surviving Corporation will prepare any Tax Returns due
to be filed by the Company after the Closing Date but relating to periods of
time prior to the Closing Date, with the understanding that such Tax Returns
will be subject to the approval of the Parent and the Sellers' Representative
prior to filing.

                                                                              59


                  (c) The Shareholders will take whatever action is necessary to
maintain the S status of the Company for federal purposes and for the purposes
of the states listed in Section 3.1(Q)(xiv) above through the Closing Date,
including as a result of the Election.

                  (d) Except in connection with the Election, the Shareholders
will not cause the Company to make any additional federal tax elections under
the Code with respect to the Company for any tax period ending after the Closing
Date.

             4.3 Further Assurances. At any time and from time to time after the
Closing, each of the parties agree to cooperate with each other and to execute
and deliver such other documents, instruments of transfer or assignment, files,
books and records and do all such further acts and things as may be reasonably
required to carry out the transactions contemplated hereunder.

             4.4 Access to Records. Prior to the Closing Date, each of the
Parent and the Merger Sub shall be entitled, through its employees and

Garrison and accountants, to make such investigation of the assets, properties,
business and operations of the Company and the Subsidiaries, and such
examination of the books, records and financial condition of the Company and the
Subsidiaries as the Parent or Merger Sub wishes. Any such investigation and
examination shall be conducted at reasonable times after providing reasonable
prior notice and under reasonable circumstances and the Company and each Seller
shall, and shall cause the Company and each of the Subsidiaries to, cooperate
reasonably therewith. No investigation by the Parent or Merger Sub shall
diminish or obviate any of the

                                                                              60


representations, warranties, covenants or agreements of the Company and each
Seller contained in this Agreement. In order that the Parent and the Merger Sub
may have the opportunity to make such business, accounting and legal review,
examination or investigation as they may wish of the business and affairs of the
Company and the Subsidiaries, the Company and the Sellers shall furnish and
shall cause the Company and the Subsidiaries to furnish the representatives of
the Parent and the Merger Sub during such period with all such information and
copies of such documents concerning the affairs of the Company and the
Subsidiaries as such representatives may reasonably request, shall make
available, or cause the Company and the Subsidiaries to make available, such
officers and employees of the Company as such representatives reasonably
request, and shall cause its officers and employees to, and use reasonable
efforts to cause its consultants, agents, accountants and attorneys to cooperate
fully with such representatives in connection with such review and examination
and to make full disclosure to the Parent and the Merger Sub of all material
facts affecting the financial condition and business operations of the Company
and the Subsidiaries. Following the Closing, each party shall afford the other
and its authorized representatives access, during regular business hours after
providing reasonable prior notice, to any books and records of the Company and
the Subsidiaries to the extent they relate to a period prior to the Closing Date
that such party shall from time to time reasonably request. From the date
hereof, at the Parent or Merger Sub's request, each Seller shall give the Parent
or Merger Sub and its authorized representatives reasonable access, during
regular business hours after providing reasonable prior notice, to such Seller's
records related to the Company

and/or the Subsidiaries located other than in the possession of the Company or
the Subsidiaries, and shall permit the Parent or Merger Sub to make a copy at
its expense of any such documents as the Parent or Merger Sub shall designate.
Notwithstanding anything to the contrary in this Section 4.4, neither the
Company nor any of the Subsidiaries shall be required to disclose any classified
information in violation of any applicable law.

             4.5 Preservation of Records. Each of the Parent and the Merger Sub
agrees that it shall at its sole expense preserve and keep the records of the
Sellers, the Company and the Subsidiaries (including any successors thereto)
delivered to it hereunder for a period of no less than six years after the
close-out of each government contract or for such longer period as may be
required by any governmental agency or on account of on-going litigation, but
for no less than one year from the Closing Date and shall make such records
available to the Company and the Sellers as may be reasonably required by the
Company and the Sellers in connection with any legal proceedings against or
governmental investigations of the Company and the Sellers or in connection with
any tax examination of the Company and the Sellers. In the event the Parent or
the Merger Sub wishes to destroy such records after that time, it shall first
give thirty (30) days' prior written notice to the Sellers' Representative and
the Sellers' Representative shall have the right at its option, upon prior
written notice given to the Parent or the Merger Sub within said thirty (30) day
period, to take possession of said records within sixty (60) days after the date
of the Sellers' Representative's notice to the Parent and the Merger Sub
hereunder. If the Sellers' Representative fails to take possession of said
records

                                                                              62


within such sixty (60) day period, the Parent or Merger Sub may destroy such
records.

until the fifth anniversary of the Closing Date, in the event of the
consummation of the transaction contemplated hereby, each Seller shall keep any
and all information relat ing to the Company and the Subsidiaries, their
business operations and prospects (including, but not limited to, customer lists
and related information), services and know-how confidential and shall not
disclose such to any person; PROVIDED, HOWEVER, that such Seller may disclose
such information that (i) is or becomes publicly available other than by
disclosure by any Seller, the Sellers' Representative or any agent thereof, (ii)
such Seller is required to disclose by law, government regulation or court order
or in order to enforce the terms of this Agreement, but such Seller will give
the Parent and the Merger Sub adequate advance notice so that the Parent and the
Merger Sub may seek a protective order or take other reasonable actions to
preserve the confidentiality of such information, or (iii) is required in the
ordinary course of such Seller's duties as director, officer or employee of the
Company or the Surviving Corporation. In the event that the transactions
contemplated hereby are not consummated, the terms of the Confidentiality

for a period of five years subsequent to the date thereof.

become necessary for the performance of its obligations pursuant to this
Agreement and the consummation of the transactions contemplated hereby and will
cooperate fully in promptly seeking to obtain such authorizations, consents,
order and approvals as may be necessary for the performance of their respective
obligations pursuant to this Agreement. Each of the Parent and the Merger Sub
will not take any action which will have the effect of delaying, impairing or
impeding the receipt of any required regulatory approvals and will use its best
efforts to secure such approvals as promptly as possible.

             4.8 Return of Information and Confidentiality. The terms of the
Confidentiality Agreement are herewith incorporated by reference and shall

accordance with the terms hereof, the Shareholders shall surrender to the
Company, the Subsidiaries, the Parent and the Merger Sub (i) all insurance
proceeds received by any of the Shareholders with respect to such damage or loss
and (ii) all rights of the Shareholders with respect to any causes of action,

Agreement, including, without limitation, the Parent or the Merger Sub's right
not to consummate the transactions contemplated hereby if all of the conditions
set forth in Section 5.2 are not satisfied or waived, in the sole discretion of

equitable and reasonable adjustments shall be made in calculating the Operating
Profit of the Company and its Subsidiaries, and consequently, the amount of
Contingent Consideration payable, if any, to eliminate the effect of any
transfer, assignment, allocation or attribution, and no such transfer,
assignment, allocation or attribution shall be made unless the financial

Sections 3.2(E) and 3.2(F) which shall not survive the Closing, (i) shall
thereafter terminate and expire twenty-four months following the Closing Date,
with respect to any General Claim (as hereinafter defined) based upon, arising

of which the party asserting such claim shall have given no notice on or prior
to the expiration of such twenty-four month period, to the party against which

inaccuracy in or any breach of any representation or warranty of any Seller
contained in this Agreement, (ii) "TAX CLAIM" means any claim based upon,

                                                                              86


health and safety. Except as otherwise expressly provided herein, the covenants
and agreements contained in this Agreement shall survive the execution and
delivery hereof and the consummation of the transactions contemplated hereby.

             8.5 Certain Limitations on Indemnification Obligations.

                  (a) The Parent and the Merger Sub shall not be entitled to
receive any indemnification payments under Section 8.1 with respect to any
inaccuracy in or breach of any representation or warranty, except those based
upon, arising out of or otherwise in respect of Sections 3.1(A), 3.1(B), 3.1(C),
3.1(D), 3.1(M), 3.1(Q) and 3.1(S), (the "BASKET EXCLUSIONS"), until the
aggregate indemnification payments, exclusive of the Basket Exclusions, equal
$350,000 (the "BASKET AMOUNT"), whereupon the Parent and the Merger Sub shall be
entitled to receive in full indemnity payments in excess of the Basket Amount;
PROVIDED, HOWEVER, that (i) solely for purposes of determining whether the
amount of the Sellers' indemnification obligations exceed $350,000 in the
aggregate, a breach of the Sellers' representations or warranties (other than
the representations and warranties contained in Sections 3.1(F) (absence of
certain changes or events) and 3.1(R)(a) (Additional Representations)) shall be
determined without regard to any limitation or qualification as to materiality
set forth in such representation or warranty and (ii) the representations and
warranties in this Agreement respecting compliance with laws and Permits set
forth in Sections 3.1(I), 3.1(G), 3.1(K)(i)(d), 3.1(K)(i)(e), 3.1(K)(ii)(d),
3.1(K)(ii)(e) and 3.1(W) shall not be deemed to be inaccurate or breached with
respect to matters involving Losses under such Sections, taken as a whole, not
exceeding $10,000 individually unless such Losses exceed $50,000 in the
aggregate.
<PAGE>

                                                                              87


                  (b) The Parent and the Merger Sub 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 (i)
under Section 8.1 with respect to any inaccuracy in or breach of a
representation or warranty (excluding those based upon, arising out of or
otherwise in respect of Sections 3.1(A), 3.1(B), 3.1(C), 3.1(D), or 3.1(Q)),
(ii) under Section 8.1(c), and (iii) under Section 8.3(c), shall not exceed in
the aggregate, with respect to claims asserted on or prior to the second
anniversary of the Closing Date the aggregate amounts owed but until then not
due to be paid under the Notes and Section 2.8 and after the second anniversary
of the Closing Date shall not exceed $6,000,000. The amount of indemnification
payments under Section 8.1 based upon, arising out of or otherwise in respect of
breaches of Sections 3.1(A), 3.1(B), 3.1(C), 3.1(D) or 3.1(Q) shall not exceed
the Purchase Price.

                  (d) The Parent and Merger Sub agree to first collect any
indemnification through set-off on a several basis against any amounts owed but
not paid under the Notes or Section 2.8 of this Agreement. All indemnification
obligations under this Article VIII or any other provision of this Agreement
shall be joint and several with respect to the Parent and the Merger Sub and
shall be several, but not joint, with respect to the Sellers; it being
understood that with respect to the Sellers, the term "several" means that each
Seller's indemnification obligation shall be
<PAGE>

                                                                              88


limited to such Seller's pro rata share of the indemnification obligation of the
Sellers, with the understanding that pro rata shall be determined by the
respective amount of consideration payable to holders of Common Stock and
Options under Sections 2.3(a), (d), (e) and 2.4(b). Each holder of Common Stock
and Options who is not a Seller hereunder shall be responsible to provide
indemnification under this Agreement to the same extent as if such holder were a
Seller hereunder.

             8.6 Defense of Claims. In the case of any claim for indemnification
under Section 8.1, 8.2 or 8.3 arising from a claim of a third party, an
indemnified party shall give prompt written notice to the indemnifying party of
any claim, suit or demand of which such indemnified party has knowledge and as
to which it may request 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 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
<PAGE>

                                                                              89


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
<PAGE>

                                                                              90


consent to settlement or compromise shall not be unreasonably withheld. 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.

             8.7 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 days after
receipt of such notice within which to respond thereto. If the recipient does
not respond within such thirty 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 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.

             8.8 Set-off Rights. Each of the Sellers agrees that the Parent and
the Merger Sub shall have the right, but not the obligation (except as set forth
in Section 8.5(d)), to set-off against their payment obligations under Section
2.8 of this Agreement or the Notes the full amount of any Losses required to be
paid by such Seller pursuant to this Article VIII if such Losses are not
otherwise paid within 30
<PAGE>

                                                                              91


days after the Parent or the Merger Sub has requested payment. If the Parent or
the Merger Sub elects to exercise its set-off rights hereunder against any
payment due to the Sellers under this Agreement, it will give to the Sellers'
Representative written notice of such election which includes the amount to be
set-off, and upon giving of such notice, the amount of cash payable by the
Parent, the Merger Sub or the Surviving Corporation to the Sellers under this
Agreement shall automatically be reduced by the amount set forth in such notice.
In the event there is a final deter mination by a court of competent
jurisdiction that the Parent, the Merger Sub or the Surviving Corporation was
not entitled to indemnification under this Article VIII with respect to the
set-off amount, the Parent, the Merger Sub or the Surviving Corporation shall
promptly thereafter repay to the Sellers all such amounts which are so
determined to have been incorrectly set-off, plus interest thereon at a rate per
annum equal to 7.5%, on the basis of a twelve-month year of thirty days each,
and which shall accrue from the date the Parent or the Merger Sub exercised its
right of set-off hereunder to the date of such repayment.

                                   ARTICLE IX

             9.2 Sellers' Representative.

                  (i) Each Seller hereby irrevocably appoints and each other
Shareholder and Option Holder by its execution and delivery of a letter of
transmittal or option cancellation and settlement form shall irrevocably appoint
Joseph Maurelli to act as such Seller's attorney-in-fact and representative (the
"SELLERS' REPRESENTATIVE"), to do any and all things and to execute any and all
documents, in such Shareholder's or Option Holder's name, place and stead, in
any way which such Shareholder or Option Holder could do if personally present,
in connection with this Agreement, and the transactions contemplated hereby and
thereby, including to accept on such Shareholder's or Option Holder's behalf any
amount payable to such Shareholder or Option Holder under this Agreement, or to
amend, cancel or extend, or waive the terms of, this Agreement. The Parent and
the Merger Sub shall be entitled to rely, as being binding upon such Shareholder
or Option Holder, upon any document or other paper believed by the Parent and
the Merger Sub to be genuine and correct and to have been signed by the Sellers'
Representative, and the Parent and the Merger Sub shall not be liable to any
Shareholder or Option Holder for any action taken or omitted to be taken by the
Parent and the Merger Sub in such reliance. The Sellers' Representative shall

<PAGE>

                                                                              97

arising under this Agreement.

                  (ii) The Sellers' Representative may resign at any time by
giving written notice of resignation to the Parent and the Merger Sub and the
Sellers and may be removed at any time with or without cause by the Sellers who
held a majority of the outstanding Common Stock of the Company at the time of
the Closing. Upon any such resignation or removal, such Sellers shall have the
right to appoint, with the consent of the Parent and the Merger Sub, a successor
Sellers' Representative. If no successor Sellers' Representative shall have been
so appointed by such Sellers, and shall have accepted such appointment, within
30 days after the retiring Sellers' Representative's giving of notice of
resignation or the Sellers' removal of the retiring Sellers' Representative,
then the retiring Sellers' Representative may, on behalf of the Shareholders and
Option Holders, appoint a successor Sellers' Representative, which shall be
acceptable to the Parent and the Merger Sub (which shall not unreasonably
withhold or delay their approval). Upon the acceptance of any appointment as
Sellers' Representative thereunder by a successor Sellers' Representative, such
successor Sellers' Representative shall thereupon succeed to and become vested
with all the rights, powers, privileges and duties of the retiring Sellers'
Representative, and the retiring Sellers' Representative shall be discharged
from its duties and obligations as Sellers' Representative under this Agreement.
After any retiring Sellers' Representative's resignation or removal hereunder as
Sellers' Representative, the provisions of this Section 9.2 shall inure to

its benefit as to any actions taken or omitted to be taken by it while it was
Sellers' Representative.

                  (iii) The grant of authority provided for in this Section 9.2:
(a) is coupled with an interest and shall be irrevocable and survive the death,
incompetency, bankruptcy or liquidation of any Shareholder or Option Holder and
shall be binding on any successor thereto; and (b) shall survive the delivery of
an assignment by a Shareholder or Option Holder of the whole or any fraction of
its interest in any payment due to it under this Agreement.

             9.3 Expenses. Unless otherwise specifically provided herein, the
parties shall bear their own respective expenses incurred in connection with the
preparation, execution and performance of this Agreement and consummation of the
transactions contemplated hereby. Notwithstanding the foregoing, the Parent and
the Merger Sub agree that if the Closing occurs and the transactions
contemplated by this Agreement are consummated, the Parent and the Merger Sub
will pay transaction expenses incurred by the Company, the Subsidiaries and the
Shareholders in respect of their outside legal, financial and accounting
advisors, up to $300,000; it being agreed by the parties hereto that any
accounting, legal and/or other expenses of the Company, the Subsidiaries and the
Sellers in excess of such specified amounts, and any other transaction expenses
of the Company, the Subsidiaries and the Sellers shall be paid solely by the
Shareholders and the Option Holders pro rata from their respective proceeds of
the transaction contemplated hereunder, and shall not be otherwise charged or
expensed to the Company.

                                                                              99


             9.4 Waivers and Amendments; Non-Contractual Remedies; PRESERVATION
OF REMEDIES. Subject to the provisions of Section 13.1-718I of the VSCA, this
Agreement may be amended, superseded, canceled, renewed or extended, and the
terms hereof may be waived, only by a written instrument signed by the Parent
and the Merger Sub and the Sellers or the Sellers' Representative 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 indemnification
provisions of Article VIII are the exclusive remedy for breaches of this
Agreement, except for equitable relief following willful failure to consummate
this Agreement. The rights and remedies herein provided are cumulative. 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
