               (viii) The "Initial Cash Purchase Price" shall mean the Base Cash
Purchase Price together with the Excess Cash Purchase Price.

               (ix)   The "Initial Stock Consideration" shall mean the Base

                  (d) At the Effective Time, (i) all shares of Company Common
Stock outstanding immediately prior to the Effective Time shall automatically be
cancelled and retired and shall cease to exist, and all holders of certificates
representing shares of Company Common Stock that were outstanding immediately
prior to the Effective Time shall cease to have any rights as shareholders of
the Company, and (ii) the stock transfer books of the Company shall be closed
with respect to all shares of Company Common Stock outstanding immediately prior

Company Common Stock (each, a "Company Stock Certificate" and collectively, the
"Company Stock Certificates") is presented to the Surviving Corporation or
Integral, such Company Stock Certificate shall be cancelled and shall be
exchanged as provided in Section 1.7.

         1.6     Determination and Payment of Contingent Purchase Price.

                 (a)  The term "Pre-Tax Earnings" means, with respect to any
Earnout Period specified on Schedule 1.6, the Surviving Corporation's aggregate
earnings before income Taxes, if any, determined in accordance with generally
accepted accounting principles ("GAAP") applied consistently with Integral's
accounting practices; provided, however, that in computing Pre-Tax Earnings for
any such Earnout Period:

                      (i)  the total amount of corporate expenses allocated to
the Surviving Corporation by Integral shall be deemed to be equal to the lesser
of (x) the actual amount of corporate expenses allocated to the Surviving
Corporation under Integral's normal accounting and business practices and (y)
$200,000; and

                      (ii) to the extent that such Pre-Tax Earnings are reduced
by reason of a set-off by Integral pursuant to Section 8.5 or a claim by
Integral against the Escrow Fund pursuant to Section 8.4, then such Pre-Tax
Earnings, as reduced by reason of such set-off or claim, shall be increased to
the extent of such set-off or Integral's recovery with respect to such claim on
a dollar-for-dollar basis.

                 (b)  Subject to Sections 1.5 and 1.7, the Contingent Purchase
Price shall be determined and paid as set forth on Schedule 1.6 and in this
Section 1.6.

                 (c)  Notwithstanding anything herein or in Schedule 1.6 to the
contrary,

                      (i)  if the aggregate Contingent Purchase Price with
respect to "Earnout Period 1," "Earnout Period 2," and "Earnout Period 3," in
each case as identified on Schedule 1.6, is equal to or greater than an amount
equal to the difference between Ten Million Dollars ($10,000,000) and the Excess
Shareholder Equity, then no Contingent Purchase Price with respect to "Earnout
Period 4" identified on Schedule 1.6 shall be paid or payable; and


                                       5



                    (ii)  if the aggregate Contingent Purchase Price with
respect to "Earnout Period 1," "Earnout Period 2," and "Earnout Period 3," in
each case as identified on Schedule 1.6, is less than an amount equal to the
difference between Ten Million Dollars ($10,000,000) and the Excess Shareholder
Equity, then the Contingent Purchase Price with respect to "Earnout Period 4"
identified on Schedule 1.6 shall be equal to the lesser of

                          (A) an amount equal to the aggregate Contingent
Purchase Price with respect to "Earnout Period 4" identified on Schedule 1.6 as
determined in accordance with Schedule 1.6; or

                          (B) an amount equal to the difference between (1) Ten
Million Dollars ($10,000,000) and (2) the sum of the aggregate Contingent
Purchase Price (without regards to the amount of any set-off by Integral
pursuant to Section 9.5) with respect to "Earnout Period 1," "Earnout Period 2,"
and "Earnout Period 3," in each case as identified on Schedule 1.6, and the
Excess Shareholder Equity.

               (d)  The following procedure and schedule of events shall be
followed with respect to the calculation and payment of the Contingent Purchase
Price with respect to any "Earnout Period" identified on Schedule 1.6.
Notwithstanding anything herein to the contrary, the payment of the Contingent
Purchase Price with respect to any Earnout Period identified on Schedule 1.6
shall be subject to Sections 1.7(d), (e), (f) and (g).

                    (i)   Not later than the December 31 of the calendar year in
which such Earnout Period ended, Integral shall deliver to the Shareholders'
Representative a statement of the Pre-Tax Earnings for such Earnout Period,
which will set forth in reasonable detail the calculation of such Pre-Tax
Earnings and the portion of the Contingent Purchase Price payable with respect
to such Earnout Period (such statement, the "Earnout Report").

                    (ii)  Not later than ten (10) days after the delivery of the
Earnout Report with respect to such Earnout Period, Integral shall pay or cause
the Surviving Corporation to pay to each Shareholder

                          (A) a cash amount, if any, equal to the product
obtained by multiplying (1) fifty percent (50%) of the Contingent Purchase Price
with respect to such Earnout Period by (2) the percentage set forth in Column C
of Schedule 1.5 opposite the name of such Shareholder; and

                          (B) a number of shares of Integral Common Stock, if
any, equal to the product obtained by multiplying (1) the Earnout Stock
Consideration by (2) the percentage set forth in Column D of Schedule 1.5
opposite the name of such Shareholder.

                    (iii) For purposes of this Agreement, the "Earnout Stock
Consideration" with respect to any Earnout Period identified on Schedule 1.6
shall mean that certain number of shares of Integral Common Stock having an
aggregate value equal to fifty

                                        6



percent (50%) of the Contingent Purchase Price with respect to such Earnout
Period. For purposes of determining the Earnout Stock Consideration with respect
to any Earnout Period pursuant to the preceding sentence, each such share of
Integral Common Stock shall be deemed to have a per share value equal to the
average of the daily last trade price of the Integral Common Stock as reported
on the Nasdaq National Market for the thirty (30) trading day period ending two
(2) trading days immediately preceding the last calendar day of such Earnout
Period.

                   (iv) Any dispute relating to the amounts shown on an Earnout
Report shall be resolved in accordance with the provisions set forth in Section
10.10; provided, however, that in the event of such a dispute, if a portion of
the Contingent Purchase Price payable with respect to the Earnout Period subject
to such Earnout Report is not subject to such dispute, then Integral shall pay
or cause the Surviving Corporation to pay to each Shareholder the portion of
such Contingent Purchase Price which is not subject to such dispute in
accordance with Sections 1.6(d)(ii) and (iii) and thereafter shall pay any
remaining portion of such Contingent Purchase Price, as adjusted in connection
with the resolution of such dispute, as soon as reasonably practicable after
such dispute is resolved.

               (e) Notwithstanding anything herein to the contrary, no holder or
former holder of Company Common Stock shall have the right to assign any right
of such holder hereunder to receive any portion of the Contingent Purchase
Price, if any, to any other party, without the prior written consent of
Integral, which consent shall not be unreasonably withheld, and provided,
however, that in the event of the death of a Shareholder, Integral shall be
deemed to have provided consent for the transfer of the right of such
Shareholder to receive a portion of the Contingent Purchase Price to such
Shareholders' heirs or beneficiaries named in the Shareholder's will.

               (f) Notwithstanding anything in this Agreement to the contrary,
in no event shall the number of shares of Integral Common Stock issued or
issuable under this Agreement, in the aggregate, exceed the lesser of (ii)
twenty percent (20%) of the number of shares of Integral Common Stock
outstanding immediately prior to the first such issuance minus one (1) share or
(ii) twenty percent (20%) of the voting power of Integral outstanding
immediately prior to the first such issuance minus one (1) vote. If, as a result
of the limitation imposed by the foregoing sentence, Integral is unable, at any
time or from time to time, to pay in shares of Integral Common Stock any portion
of the Contingent Purchase Price that otherwise would be due and payable
hereunder, Integral shall pay such portion of the Contingent Purchase Price in
cash or in such other consideration of equivalent aggregate value as the parties
may reasonably agree, provided that such payment shall preserve the tax-free
nature of the reorganization.

         1.7   Payment of Purchase Price.

               (a) Payment of the Base Cash Purchase Price. Subject to the
delivery of such letters, signatures pages, agreements and other documents as
are or may be required under Section 1.7(d), at the Effective Time, Integral
shall:

                                        7



                    (i)   Wire to each Shareholder the cash amount set forth in
Column A1 of Schedule 1.5 opposite such Shareholder's name.

                    (ii)  Wire to the Escrow Agent, to secure certain
indemnification obligations of each Shareholder hereunder, the cash amount set
forth in Column A2 of Schedule 1.5 opposite such Shareholder's name (the "Cash
Escrow").

                    (iii) Wire to the Company, on behalf of each Shareholder
indebted to the Company, the cash amount set forth in Column A3 of Schedule 1.5
opposite such Shareholder's name.

                    (iv)  Wire to the Shareholders' Representative, on behalf of
each Shareholder, the cash amount set forth in Column A4 of Schedule 1.5
opposite such Shareholder's name.

               (b)  Payment of Base Stock Consideration. Subject to the delivery
of such letters, signature pages, agreements and other documents as are or may
be required under Section 1.7(d), at or as soon as reasonably practicable after
the Effective Time, Integral shall:

                    (i)   Deliver to each Shareholder a certificate representing
the number of shares set forth opposite such Shareholder's name in Column B1 of
Schedule 1.5.

                    (ii)  Deliver to the Escrow Agent, to secure certain
indemnification obligations of each Shareholder hereunder, a single certificate
representing the shares of Integral Common Stock set forth in Column B2 of
Schedule 1.5 (the "Escrow Shares), which certificate shall be issued in the name
of the Escrow Agent and for the benefit of Integral (subject to the terms of
this Agreement and the Escrow Agreement).

               (c)  Within fifteen days after the Closing Date, the
Shareholders' Representative shall deliver to Integral the Closing Date Balance
Sheet. No later than ten (10) days after the receipt by Integral of the Closing
Date Balance Sheet, Integral shall, unless it disputes the Closing Date Balance
Sheet,

                    (i)   pay or cause the Surviving Corporation to pay to each
Shareholder a cash amount equal to the product obtained by multiplying (A) the
Excess Cash Purchase Price by (B) the percentage set forth in Column C of
Schedule 1.5 opposite the name of such Shareholder, and

                    (ii)  deliver to each Shareholder a certificate representing
the number of shares of Integral Common Stock equal to the product obtained by
multiplying (A) the Excess Stock Consideration by (B) the percentage set forth
in Column D of Schedule 1.5 opposite the name of such Shareholder.

If Integral disputes the Closing Date Balance Sheet, such dispute shall be
resolved in accordance with the provisions set forth in Section 10.10 and the
Excess Cash Purchase Price and the Excess

                                        8



Stock Consideration shall be adjusted in a manner consistent with such
resolution; provided, however, that in the event of such a dispute, if a portion
of the Excess Purchase Price is not subject to such dispute, then Integral shall
pay or cause the Surviving Corporation to pay the portion of the Excess Purchase
Price which is not subject to such dispute in accordance with Sections 1.7(c)(i)
and (ii), above, and thereafter shall pay any remaining portion of the Excess
Purchase Price, as adjusted in connection with the resolution of such dispute,
as soon as reasonably practicable after such dispute is resolved.

            (d)   At the Closing, the Company shall deliver to Integral, on
behalf of each Shareholder:

                  (i)   the Company Stock Certificate(s) representing the shares
of Company  Common  Stock held by such Shareholder;

                  (ii)  a duly executed letter of transmittal and stock power in
the form attached hereto as Exhibit 1.7(d)(ii);

                  (iii) for the Shareholders who are receiving Integral Common
Stock hereunder, an executed signature page to the Investment Agreement, a form
of which is attached hereto as Exhibit 1.7(d)(iii) (the "Investment Agreement");
and

                  (iv)  for the Shareholders who are not receiving Integral
Common Stock hereunder, an executed signature page to the Shareholder's
Representation Agreement, a form of which is attached hereto as Exhibit
1.7(d)(iv) (the "Shareholder's -- Representation Agreement"); and

                  (v)   for Shareholders who are receiving Integral Common Stock
hereunder, a questionnaire in the form attached to the Investment Agreement as
an exhibit thereto.

Notwithstanding anything herein to the contrary, upon surrender or delivery of a
Company Stock Certificate to Integral by or on behalf of the holder thereof and
delivery of such other letters, signatures pages, agreements and other documents
as are or may be required under subsections (ii) through (iv) of this Section
1.7(d) by or on behalf of such holder, and only upon such delivery or surrender,
(A) the holder of such Company Stock Certificate shall be entitled to receive in
exchange therefor the applicable Purchase Price payable at such time to such
holder pursuant to the terms of this Agreement (including without limitation any
portion of the Contingent Purchase Price payable at such time), and (B) the
Company Stock Certificate so surrendered shall be immediately cancelled. Until a
Company Stock Certificate is surrendered as contemplated by this Section 1.7 and
until the delivery of such letters, signature pages, agreements and other
documents as are or may be required under the immediately preceding sentence,
such Company Stock Certificate shall be deemed, from and after the Effective
Time, to represent only the right to receive the applicable Purchase Price
payable at such time with respect to such Company Stock Certificate pursuant to
the terms of this Agreement. If any Company Stock Certificate shall have been
lost, stolen or destroyed, Integral will accept, in lieu of receipt of such
Company Stock Certificate, an appropriate affidavit, in form and substance
satisfactory to Integral, providing for indemnity against any claim that may be
made against Integral or the Surviving Corporation with respect to such Company

                                        9



Stock Certificate, and, in such case, Integral or the Surviving Corporation will
issue in exchange for such lost, stolen or destroyed Company Stock Certificate
the applicable Purchase Price payable at such time with respect to such Company
Stock Certificate pursuant to the terms of this Agreement.

         (e)   Integral and the Surviving Corporation shall be entitled to
deduct and withhold from any consideration payable or otherwise deliverable
pursuant to this Agreement to any holder or former holder of Company Common
Stock such amounts as may be required to be deducted or withheld therefrom under
the Code or any provision of state, local or foreign tax law or under any other
applicable legal requirement. To the extent such amounts are so deducted or
withheld, such amounts shall be treated for all purposes under this Agreement as
having been paid to the person to whom such amounts would otherwise have been
paid.

         (f)   Integral shall calculate the amount payable to each holder or
former holder of Company Common Stock pursuant to the terms of this Agreement,
after taking into account any deductions pursuant to Section 1.7(e), the amount
of any set-off(s) by Integral pursuant to Section 8.5, and any other deductions
required by order of a court of competent jurisdiction. Subject to Section
1.7(a), all cash amounts due and payable pursuant to the terms of this Agreement
shall be rounded to the nearest whole cent. No fraction of a share of Integral
Common Stock will be issued in connection with the Merger. In lieu of such
issuance, all shares of Integral Common Stock issued to the Shareholders shall
be rounded to the closest whole share of Integral Common Stock.

         (g)   Neither Integral nor the Surviving Corporation shall be liable to
any holder or former holder of Company Common Stock or to any other person with
respect to any cash amounts delivered to any public official in compliance with
any applicable abandoned property law, escheat law or similar legal requirement.

   1.8   Appraisal Rights.

         (a)   Notwithstanding any provision of this Agreement to the contrary,
any shares of Company Common Stock held by a holder who, as of the Effective
Time, has not effectively withdrawn or lost (through failure to perfect or
otherwise) appraisal or dissenters' rights pursuant to Article 113 of the CBCA
(the "Dissenting Shares") shall not be converted into or represent the right to
receive any of the Purchase Price pursuant to this Article 1, but the holder
thereof shall only be entitled to such rights as are granted by the CBCA.

         (b)   Notwithstanding the provisions of Section 1.8(a), if after the
Effective Time any holder of Dissenting Shares shall effectively withdraw or
lose (through failure to perfect or otherwise) the right to appraisal, then, as
of the occurrence of such event, such holder's shares of Company Common Stock
shall automatically be converted into and represent only the right to receive
the Purchase Price with respect to such shares pursuant to this Article 1,
without interest thereon, upon surrender of the Company Stock Certificate(s)
representing such shares.

         (c)   The Company shall give Integral prompt notice of any written
demands for appraisal with respect to any shares of Company Common Stock,
withdrawals of such demands,

                                       10



and any other instruments served pursuant to the CBCA (including without
limitation instruments concerning appraisal or dissenters' rights) and received
by the Company prior to the Effective Time. The Company shall not, except with
the prior written consent of Integral, voluntarily make any payment with respect
to any demands for appraisal with respect to any shares of Company Common Stock
or offer to settle any such demands.

2.    CLOSING

      2.1   Closing. The closing of the transactions contemplated by this

         3.3      Capitalization of the Company.

                  (a) The authorized capital stock of the Company consists of
Twenty-Five Million (25,000,000) shares of Company Common Stock, of which Two
Million Four Hundred Ninety-Eight Thousand (2,498,000) shares are issued and
outstanding (the "Outstanding Shares"). The Outstanding Shares have been duly
authorized and validly issued, are fully paid and nonassessable, and are owned
of record and beneficially by the Shareholders, in the respective amounts set
forth on Schedule 3.3, free and clear of any and all pledges, security
interests, voting or transfer restrictions, liens, encumbrances and claims of
every kind ("Liens"), except as set forth on Schedule 3.3 attached hereto.
Except as set forth on Schedule 3.3, all of the Outstanding Shares were offered,
issued, sold and delivered by the Company in compliance with all applicable
state and federal laws concerning the issuance of securities. None of such
shares was issued in violation of any preemptive rights created by statute, by
the Charter Documents or by any agreement to which the Company may be bound. All
of the issued and outstanding shares of the Company Common Stock are subject to
repurchase upon termination of employment, which such repurchase right shall be
terminated at the Effective Time.

                  (b) Other than the issued and outstanding shares of Company
Common Stock owned by the Shareholders and set forth on Schedule 3.3, there are
no authorized or issued and outstanding shares of Company Common Stock,
preferred stock or any other equity securities of the Company. There are no
options, warrants, calls, conversion rights, preemptive rights, commitments or
agreements of any character to which the Company or the Major Shareholders or,
to the knowledge of the Company and each of the Major Shareholders, any other
Shareholder is a party or by which the Company or any of the Major Shareholders
may be bound that obligate or may obligate the Company to issue, deliver or
sell, or cause to be issued, delivered or sold, additional shares of common
stock, preferred stock or other equity securities of the Company or that
obligate or may obligate the Company to grant, extend or enter into any such
option, warrant, call, conversion right, preemptive right, commitment or
agreement. No former holder of any option, warrant or other right to purchase
any securities of the Company shall have any claim or cause of action against
the Company, the Surviving Corporation or Integral as a result of, arising from,
or relating to (x) such option, warrant or other rights or (y) the exercise,
cancellation or termination of such option, warrant or other right. Other than
as set forth on Schedule 3.3 attached hereto, there are no outstanding
arrangements, agreements, commitments or understandings of any kind affecting or
relating to the voting, issuance, purchase, redemption, repurchase or transfer
of any capital stock of the Company or any other securities of the Company.
Other than as provided in or contemplated by this Agreement or set forth on
Schedule 3.3 attached hereto, neither the Company nor any of the Major
Shareholders has become, nor, to the knowledge of the Company and each of the
Major Shareholders, has any other Shareholder become, party to or subject to any
contract or obligation wherein any person has a right or option to purchase or
acquire any rights in any capital stock or securities of the Company. Except as
set forth in Section 1.8, immediately after the Closing, as a result of the
transactions contemplated by this Agreement, Integral will own free and clear of

Except as set forth on Schedule 3.15(a), each item of Intellectual Property
owned or used by the Company immediately prior to the Closing hereunder will be
owned or available for use by the Surviving Corporation on identical terms and
conditions immediately subsequent to the Closing hereunder. The Company has
taken commercially reasonable action to maintain and protect each item of
Intellectual Property that it owns or uses. Without limiting the foregoing, the
Company has and enforces a policy requiring each officer, employee, consultant
and contractor who or which has contributed to or participated in the conception
and/or development of any Intellectual Property on behalf of the Company
(including without limitation Intellectual Property owned or used by the
Company) (i) to execute a proprietary information, confidentiality and
assignment agreement that is reasonably sufficient to maintain and protect each
item of Intellectual Property that the Company owns or uses or (ii) to become a
party to a "work-for-hire" arrangement or agreement with the Company, in
accordance with applicable federal and state law, that has accorded the Company
full, effective, exclusive and original ownership of all Intellectual Property
arising in connection therewith, and each current and former employee, officer,
contractor and consultant of the Company who or which has contributed to or
participated in the conception and/or development of any Intellectual Property
on behalf of the Company (including without limitation Intellectual Property
owned or used by the Company) has executed such a proprietary information,
confidentiality and assignment agreement or become a party to such a
"work-for-hire" arrangement or agreement.

                (b)  The Company has not interfered with, infringed upon,
misappropriated, or otherwise come into conflict with any Intellectual Property
rights of third parties, and neither the Company nor any of the Major
Shareholders, nor any of the directors or officers (and employees with
responsibility for Intellectual Property matters) of the Company or any Major
Shareholder that is an entity, respectively, has ever received any charge,
complaint, claim, demand or notice alleging any interference, infringement,
misappropriation or violation of the Intellectual Property rights of third
parties, and no such charge, complaint, claim, demand or notice has been
asserted (including without limitation any claim that the Company must license
or refrain from using any Intellectual Property rights of any third party), and
the Company and each of the Major Shareholders do not know of any basis for any
such charge, complaint, claim, demand or notice. The use of the Intellectual
Property owned or used by the Company, or licensed or sublicensed to any person
by the Company, does not infringe upon the rights of any other person. To the
knowledge of the Company and each of the Major Shareholders, no third party has
interfered with, infringed upon, misappropriated or otherwise come into conflict
with any Intellectual Property rights of the Company.

                (c)  Schedule 3.15(c) identifies each patent, copyright,
trademark or registration which has been issued to the Company with respect to
any of its Intellectual Property, identifies each pending patent application or

pay, occupational health and safety, equal opportunity, collective bargaining
and the payment of social security and other Taxes, the Worker Adjustment and

           3.18   Employee Benefit Plans.

                  (a)   All employee compensation, incentive, fringe or benefit
plans, programs, policies, commitments or other arrangements (whether or not set
forth in a written document) covering any active, former or retired employee or
consultant of the Company, or any trade or business (whether or not
incorporated) which is a member of a controlled group or which is under common
control with the Company within the meaning of Section 414 of the Code, or with
respect to which the Company has or may in the future have liability, are listed
on Schedule 3.18 (individually, the "Plan" and collectively, the "Plans").
Copies of all such written plans and summaries of any other plans which cover
active, former or retired employees or consultants of the Company have been
provided to Integral. To the extent applicable, the Plans comply with the
requirements of the Employee Retirement Income Security Act of 1974, as amended
("ERISA"), and the Code, and any Plan intended to be qualified under Section
401(a) of the Code (i) has been timely amended for so-called GUST legislation
and is the subject of an IRS determination letter, opinion letter (as a
prototype plan) or advisory letter (as a volume submitter) or (ii) is within the
remedial amendment period for such amendments described in IRS Rev. Procs.
2000-27 and 2001-55. The Company has furnished or made available to Integral
copies of the most recent Internal Revenue Service determination, opinion and/or
advisory letters, if any, and Forms 5500 for the three (3) most current Plan
years with respect to any such Plan. No Plan is covered by Title IV of ERISA or
Section 412 of the Code. Neither the Company nor any of its affiliates has been
a contributing employer to any multiemployer plan as defined under Section 4001
of ERISA. Neither the Company nor any officer or director of the Company has
incurred any liability or penalty under Section 4971 through 4980E of the Code
or Title 1 of ERISA. None of the Plans promises or provides retiree medical or
other retiree welfare benefits to any person except as required by applicable
law, including without limitation the Consolidated Omnibus Budget Reconciliation
Act of 1985, as amended. Each Plan has been maintained and administered in all
material respects in compliance with its terms and with the requirements
prescribed by any and all statutes, orders, rules and regulations, including
without limitation ERISA and the Code, which are applicable to such Plans. No
suit, action or other litigation (excluding claims for benefits incurred in the
ordinary course of Plan activities) has been brought or, to the knowledge of the
Company and each of the Major Shareholders, is threatened, nor has any
investigation or audit by a Governmental Authority been undertaken, against or
with respect to any such Plan. All contributions, reserves or premium payments
required to be made or accrued as of the date hereof to the Plans have been made
or accrued. Schedule 3.18 includes a listing of the accrued vacation liability
of the Company as of the Interim Balance Sheet Date. All reports, returns, forms
and notices required to be filed with any government agency or furnished to
participants or beneficiaries with respect to the Plans, by the Code, ERISA or
any other applicable law, have been so filed and furnished. Except as set forth
on Schedule 3.18, the Company is under no legal or contractual obligation to
continue any of the Plans and may terminate any or all of the Plans at any time
without incurring any liability, except for liabilities accrued under the Plans
for the period ending on or before the termination of the Plans.

                  (b)   The Company is not bound by or subject to (and none of
its respective assets or properties is bound by or subject to) any arrangement
with any labor union. No

                                       28



employee of the Company is represented by any labor union or covered by any
collective bargaining agreement and, to the knowledge of the Company and each of
the Major Shareholders, no campaign to establish such representation is in
progress. There is no pending or, to the knowledge of the Company and each of
the Major Shareholders, threatened labor dispute involving the Company and any
group of its employees nor has the Company experienced any labor interruptions
over the past three (3) years, and the Company and each of the Major
Shareholders considers the Company's relationship with its employees to be good.

                  (c)   Neither the execution and delivery of this Agreement nor
the consummation of the transactions contemplated hereby will (i) result in any
payment (including without limitation severance, unemployment compensation,
bonus or otherwise) becoming due to any director, officer or employee of the
Company under any Plan or otherwise, (ii) result in a payment or benefit
becoming due to any director, officer or employee of the Company under any Plan
or otherwise which will be characterized as a "parachute payment" within the
meaning of Code Section 280G (but without regard to clause (b)(2)(A)(ii)
thereof), (iii) materially increase any benefits otherwise payable under any
Plan, or (iv) result in the acceleration of the time of payment or vesting of
any such benefits. Nothing in this Section 3.18(c) shall be deemed to apply to
payments to any employee, director or officer in their capacity as a
Shareholder.

                  (d)   The Company has complied with the continuation health
care coverage requirements of Section 4980B of the Code and Sections 601 through
608 of ERISA with respect to "qualifying events," as defined in the Code and
ERISA, which occur on or before the Closing with respect to any current or
former employees of the Company and their respective "qualified beneficiaries,"
as defined in the Code and ERISA, and with the requirements of the Health
Insurance Portability and Accountability Act and other applicable health
insurance requirements in Section 4980D of the Code and Sections 701 through 734

           3.19   Conformity with Law; Litigation.

                  (a)   The Company is in compliance and has conducted its
business so as to comply with all laws, rules and regulations, judgments,
decrees or orders of any Governmental Authority applicable to its operations or
with respect to which compliance is a condition of engaging in the business
thereof. There are no judgments or orders, injunctions, decrees, stipulations or
awards (whether rendered by a court or administrative agency or by arbitration)
against the Company or against any of its properties or businesses or against
any of the Major Shareholders. Without limiting the generality of the foregoing,
the Company has not violated any United States or foreign import and export
control laws and regulations, export licensing laws and regulations or customs
regulations (including without limitation its obligations under the Foreign
Corrupt Practices Act) applicable to the Company. The Company has not been cited
by the United States Department of Commerce, the United States Customs Service
or any other relevant Governmental Authority for any violation of United States
laws or regulations relating to importing or exporting of products, materials or
services. Schedule 3.19 contains a summary of any violation of, or conflict
with, any applicable statute, law, rule, regulation, ruling, order, judgment or
decree of which such Governmental Authority has notified the Company or any of
the Major Shareholders, including any of the foregoing relating to Environmental
Laws.

                  (b)   Except as set forth in Schedule 3.19, there is no
action, suit, proceeding, claim, arbitration or investigation pending against
the Company or any of the Major Shareholders or, to the knowledge of the Company
and each of the Major Shareholders, threatened against the Company or any of the
Major Shareholders, or which in any manner challenges or seeks to prevent,
enjoin, alter or delay any of the transactions contemplated hereby. Schedule
3.19 sets forth with respect to each pending action, suit, proceeding, claim,
arbitration or investigation to which the Company or any of the Major
Shareholders is a party, the forum, the parties thereto, a brief description of
the subject matter thereof and the amount of damages claimed. Except as stated
in Schedule 3.19, neither the Company nor any of the Major Shareholders is aware
of any reasonable basis for any other such litigation. The Company has delivered
or made available to Integral true, correct and complete copies of all
correspondence prepared by the Company's counsel for the Company's independent
public accountants in connection with all completed audits or reviews of the
Company's financial statements and any such correspondence since the date of the
last such audit or review. Schedule 3.19 accurately describes all product
liability claims made against the Company since inception.

           3.20   Taxes.

                  (a)   All Tax Returns required to be filed by the Company or
on its behalf have been filed. All such Tax Returns were true, correct and
complete in all respects. All Taxes owed by the Company (whether or not shown on
any Tax Return) have been paid except for taxes not yet due. Neither the
Company, nor any of the Major Shareholders on behalf of the Company, is
currently the beneficiary of any extension of time within which to file any Tax
Return. To the knowledge of the Company and each of the Major Shareholders, no
claim has ever been made by an authority in a jurisdiction where the Company
does not file Tax Returns that it is or may be

                                       30



subject to taxation by that jurisdiction. There are no security interests on any
of the assets of the Company that arose in connection with any failure (or
alleged failure) to pay any Tax.

                  (b)   Except as set forth in Schedule 3.20, the Company has
withheld and paid all Taxes required to have been withheld and paid in
connection with amounts paid or owing to any employee, independent contractor,
creditor, shareholder or other third party.

                  (c)   Neither the Major Shareholders nor any director or
officer (or employee responsible for Tax matters) of the Company expects any
authority to assess any additional Taxes for any period for which Tax Returns
have been filed. There is no dispute or claim concerning any Tax liability of
the Company either (i) claimed or raised by any authority in writing or (ii) as
to which the Company or any of the Major Shareholders has knowledge based upon
contact with any agent of such authority. The Company has delivered to Integral
true, correct and complete copies of all federal income Tax Returns, examination
reports, and statements of deficiencies assessed against or agreed to by or on
behalf of the Company since inception.

                  (d)   Neither the Company, nor any of the Major Shareholders
on behalf of the Company, has ever waived any statute of limitations in respect
of Taxes or agreed to any extension of time with respect to a Tax assessment or
deficiency.

                  (e)   Neither the Company, nor any of the Major Shareholders
on behalf of the Company, has ever filed a consent under Code section 341(f)
concerning collapsible corporations. The Company, or the Major Shareholders on
the Company's behalf, has disclosed on its federal income Tax Returns all
positions taken therein, if any, that such persons have been advised could give
rise to a substantial understatement of federal income Tax within the meaning of
Code section 6662. The Company is not a party to or bound by (or will prior to
the Closing Date become a party to or bound by) any Tax indemnity, Tax
allocation or Tax sharing agreement (whether written, unwritten or arising under
operation of federal law as a result of being a member of a group filing
consolidated Tax Returns, under operation of certain state laws as a result of
being a member of a unitary group, or under comparable laws of other states or
foreign jurisdictions). Neither the Company nor the Surviving Corporation, nor
the Major Shareholders on behalf of the Company or the Surviving Corporation,
has ever been or, to the knowledge of the Company or any of the Major
Shareholders, will ever be required to include any material adjustment in
taxable income for any Tax period (or portion thereof) ending on or after the
Closing Date pursuant to Code Sections 481 or 263A as a result of transactions,
events or accounting methods employed prior to the Closing Date.

                  (f)   The Company does not have any liability for the Taxes of
any person other than the Company (A) under Reg. (S)1.1502-6 (or any similar
provision of state, local, or foreign law), (B) as a transferee or successor,
(C) by contract, or (D) otherwise.

                  (g)   For purposes hereof, the term "Tax" or "Taxes" means (i)
any federal, state, local, or foreign income, gross receipts, license, payroll,
employment, excise, severance, stamp, occupation, premium, windfall profits,
environmental (including taxes under Code Section 59A), customs duties, capital
stock, franchise, profits, withholding, social security (or similar),

                                       31



unemployment, disability, real property, personal property, sales, use,
transfer, registration, value added, alternative or add-on minimum, estimated,
or other tax of any kind whatsoever, including any interest, penalty, or
addition thereto, whether disputed or not, and (ii) any liability for the
payment of any amounts of the type described in clause (i) as a result of being
a member of an affiliated, consolidated, combined or unitary group for any
taxable period and (iii) any liability for the payment of any amounts of the
type described in clause (i) or (ii) as a result of any express or implied
obligation to indemnify any other person. The term "Tax Return" means any
return, declaration, report, claim for refund, or information return or
statement relating to Taxes, including without limitation any schedule or
attachment thereto, and including without limitation any amendment thereof.

           3.21   Absence of Changes. Since the Interim Balance Sheet Date and
except as set forth on Schedule 3.21, there has not been:

                  (a)   any change that by itself or together with other

without limitation intangible assets), liabilities, financial condition, results
of operations or prospects of the Company (a "Material Adverse Effect");

                  (b)   any damage, destruction or loss (whether or not covered
by insurance) materially adversely affecting the properties or business of the
Company;

to the Company's established business practices;

           (o)  any violation of or conflict with any applicable laws, statutes,

related to the exercise of options to purchase shares of Company Common Stock by
such Shareholders, neither the Shareholders nor any employee, officer or
director of the Company, or their spouses or children, is indebted to the

any law, certification, representation, clause, provision or requirement

or Government Subcontract has been withheld or set off nor has any claim been
made to withhold or set off money and the Company is entitled to all progress

           (c)  (i) neither the Company nor any of its directors, officers,
employees, consultants or agents is or during the past three (3) years has been
under administrative, civil or criminal investigation, indictment or information
by any Governmental Authority or any audit or investigation of any of the Major
Shareholders or the Company or any other person with respect to any alleged
irregularity, misstatement or omission arising under or relating to any
Government Contract or Government Subcontract, and (ii) during the past three
(3) years, neither the Company nor any affiliate of the Company has conducted or
initiated any internal investigation or made a voluntary disclosure to any
Governmental Authority with respect to any alleged irregularity, misstatement or
omission arising under or relating to a Government Contract or Government
Subcontract. There exists no irregularity, misstatement or omission arising
under or relating to any Government Contract or Government Subcontract that has
led during the last three (3) years to any of the consequences set forth in

penalty assessment, recoupment of payment or disallowance of cost.

           (d)  there exist: (i) no outstanding claims against the Company,

vendor or other person, arising under or relating to any Government Contract or
Government Subcontract and (ii) no material disputes between the Company and any

Except for claims for payment of fees and purchase prices in the ordinary course
of business, the Company does not have any interest in any pending or potential
claim against any Governmental Authority or any prime contractor, subcontractor
or vendor arising under or relating to any Government Contract or Government
Subcontract. Schedule 3.26 lists each Government Contract or Government
Subcontract which is currently under audit by any Governmental Authority or any
other person that is a party to such Government Contract or Government
Subcontract. The Company has not received any draft or final post award audit
report, any draft or final notice of cost disallowance, or any draft or final
notice of noncompliance with any cost accounting standard and there exists no
basis upon which any Governmental Authority could disallow any costs in any
pending audits, and that all information provided by the Company for any such
audits was current, complete and accurate and in compliance with applicable
regulations and cost accounting standards.

           (e)  the Company has not been debarred or suspended from
participation in the award of contracts with any Governmental Authority
(excluding for this purpose ineligibility to bid on certain contracts due to
generally applicable bidding requirements). There exist no facts or
circumstances that would warrant suspension or debarment or the finding of
nonresponsibility or ineligibility on the part of the Company or any director or
officer of the Company. No payment has been made by the Company or by any person
on behalf of the Company in connection with any Government Contract or
Government Subcontract in violation of applicable procurement laws or in
violation of, or requiring disclosure pursuant to, the Foreign Corrupt Practices
Act. The Company's cost accounting and procurement systems and the associated
entries reflected in the Company's Financial Statements with respect to the
Government Contracts and Government Subcontracts are in compliance in all
material respects with all applicable laws.

           (f)  all material test and inspection results provided by the Company
to any Governmental Authority pursuant to any Government Contract or Government
Subcontract or to any other person pursuant to a Government Contract or
Government Subcontract or as a part of the delivery to any Governmental
Authority or to any other person pursuant to a Government Contract or Government
Subcontract of any article designed, engineered or manufactured by the Company
were complete and correct in all material respects as of the date so provided
and any services provided by the Company were in compliance with industry
standards and applicable representations, warranties and certifications. The
Company has provided all material test and inspection results to any person
pursuant to a Government Contract or Government Subcontract as required by law
and the terms of the applicable Government Contracts or Government Subcontracts.

           (g)  For purposes hereof, the term "Government Contract" means any
contract between the Company and any Governmental Authority, and any bids or
proposals for any contract between the Company and any Governmental Authority,
and the term "Government Subcontract" means any contract that is a subcontract
between the Company and any third party relating to a prime contract with any
Governmental Authority and any bids or proposals for any contract that is a
subcontract between the Company and any third party relating to a prime contract
with any Governmental Authority.

     3.27  Disclosure. No representation or warranty made by the Company or any
of the Major Shareholders in this Agreement, nor any financial statement, other
written financial

                                       36



information or schedule, certificate, schedule, exhibit or other materials
prepared and furnished or to be prepared and furnished by the Company or any of
the Major Shareholders or their respective representatives or agents pursuant
hereto or in connection with the transactions contemplated hereby, contains or
will contain any untrue statement of a material fact, or omits or will omit to
state a material fact necessary to make the statements or facts contained herein
or therein not misleading in the light of the circumstances under which they
were furnished. Notwithstanding the foregoing, the Parties acknowledge that the
only projections provided by the Company are those shown on Schedule 3.27. There
is no event, fact or condition that has caused, or that reasonably could be
expected to cause, a Material Adverse Effect, that has not been set forth in
this Agreement or the schedules attached hereto. Any financial projections
relating to the Company which were delivered to Integral prior to the date of
this Agreement ("Financial Projections") constitute the Company's best estimate
of the information purported to be shown therein. The Company prepared such
projections in good faith based upon reasonable assumptions, and the Company and
each of the Major Shareholders believe that there is a reasonable basis for such
projections. Neither the Company nor any of the Major Shareholders is aware of
any fact or information that would lead it to believe that the Financial
Projections are misleading in any material respect.

corporate action on the part of Integral and the Merger Sub, respectively. This

Sub, enforceable against Integral and the Merger Sub, respectively, in
accordance with its terms, except as such enforceability may be limited by
principles of public policy and subject to the laws of general application
relating to bankruptcy, insolvency and the relief of

                                       37

bylaws of Integral, in each case as amended and now in effect;

           (b)  conflict with, or result in any breach or default (or would

under, or give rise to a right of termination, cancellation or acceleration of
any obligation or to a loss of a benefit under, or result in the creation or
imposition of any lien, charge or encumbrance on any of the assets or properties
of Integral pursuant to any agreement, contract, note, mortgage, indenture,
lease, sublease, instrument, permit, concession, franchise or license to which
Integral is a party or by which Integral or any of its properties or assets may

the same class and series, and have the same rights, preferences and privileges

                                       38



     4.6   SEC Filings; Financial Statements.

           (a)  As of the time it was filed with the Securities and Exchange
Commission (the "SEC") (or, if amended or superseded by a filing prior to the
date of this Agreement, then on the date of such filing), each document filed by
Integral with the SEC between September 30, 2001, and the date of this Agreement
(the "Securities Documents"): (i) complied in all material respects with the
applicable requirements of the Securities Act or the Exchange Act (as the case
may be); and (ii) did not contain any untrue statement of a material fact or

change in the business, assets or condition (financial or otherwise) of Integral
or its subsidiaries which would require public disclosure and which has not been
publicly disclosed.

           (c)  To the knowledge of Integral, there are no circumstances or
facts which would preclude Integral from effecting the registration of the
Initial Stock Consideration using a Form S-3 registration statement as

Commission is not planning any investigation or inquiries into the financial

Corporation from engaging in the business of the Company as it is now conducted,
or as it is proposed to be conducted by the Company and disclosed to Integral.

     4.8   Rule 16a-1. As of the date hereof, it is not the intention of
Integral that any Major Shareholder will perform policy-making functions for

as that term is defined in Rule 16a-1 promulgated under the Exchange Act.

5.   ADDITIONAL AGREEMENTS

     Each of the Parties will use its reasonable best efforts to take all action
and to do all things necessary, proper or advisable in order to consummate and

6.   POST-CLOSING COVENANTS AND OTHER AGREEMENTS

     6.1 Confidentiality. Each of the Major Shareholders recognizes and
acknowledges that it has had in the past, currently has, and in the future may
possibly have, access to certain confidential information of the Company, the
Surviving Corporation and/or Integral, including without limitation lists of
customers, operational policies, and pricing and cost policies, that are
valuable, special and unique assets of the Company's, the Surviving
Corporation's and/or

                                       39



Integral's respective businesses. Each of the Major Shareholders agrees that,
after Closing, it will not use or disclose, and it will cause its officers,
directors, employees, representatives, agents and advisors (as the case may be)
not to use or disclose, confidential information with respect to the Company,
the Surviving Corporation and/or Integral to any person, firm, corporation,
association or other entity for any purpose or reason whatsoever, except to
authorized representatives of Integral and counsel and other advisers of the
Major Shareholders provided that such advisors agree to the confidentiality
provisions of this Section 6.1. The restrictions of this Section 6.1 shall not
apply (i) to confidential information of the Company, the Surviving Corporation
and/or Integral which becomes generally known to the public through no fault of
any of the Major Shareholders or any of their respective employees,
representatives, agents or advisors (as the case may be), (ii) if disclosure is
required by law or the order of any Governmental Authority under color of law,
or (iii) if the disclosing party reasonably believes that such disclosure is
required in connection with the defense of a lawsuit against the disclosing
party; provided, however, that prior to disclosing any information pursuant to
clause (ii) or (iii) above, each of the Major Shareholders shall, if reasonably
possible, give prior written notice thereof to Integral and provide Integral
with the opportunity to contest such disclosure.

     6.2   Operation of the Surviving Corporation Subsequent to the Closing.
None of the Major Shareholders, after the Closing and for the period of time set
forth in Section 9.1, will take any action that is designed or intended to have
the effect of discouraging any lessor, licensor, customer, supplier or other
business associate of the Company from maintaining the same business
relationships with the Surviving Corporation after the Closing as it maintained
with the Company prior to the Closing. Further, the Parties agree that, after
the Closing Date, the Surviving Corporation will be operated in accordance with
the provisions of the operating guidelines attached hereto as Schedule 6.2.

     6.3   Allocation of Purchase Price. To the extent required by applicable
law, the Parties agree that the Purchase Price and the liabilities of the
Company (plus other relevant items) will be allocated to the assets of the
Surviving Corporation for Tax purposes in a manner consistent with the
allocation to be agreed upon in good faith by the Parties within sixty (60) days
following the Closing Date. Integral, the Surviving Corporation and the Major
Shareholders will file all Tax Returns (including amended returns and claims for
refund) and information reports in a manner consistent with any such allocation.

     6.4   Integral Filings. Integral will use commercially reasonable efforts
to assure that all filings of Integral required by the Securities Act and the
Exchange Act are made in a manner which will allow Integral to effect
registration of the shares of Integral Common Stock issued in connection with
the Contingent Purchase Price using Form S-3.

     6.5   Tax Returns. The Company or the Shareholders' Representative, on
behalf of the Company or the Surviving Corporation (as the case may be), shall
timely file (including without limitation extensions of time to file) all
federal and state income tax returns for taxable periods ending on or prior to
the Closing Date and have paid or will pay all Taxes attributable to such
periods (the "Final Tax Returns"). In addition, immediately after filing such
tax returns, the Company or the Shareholder's Representative shall file all
federal, state and local income tax

                                       40



refund claims (the "Tax Refund Claims") arising by reason of the operating
losses set forth on the Final Tax Returns. Such returns will be prepared and
filed in accordance with applicable law and in a manner consistent with past
practices and shall be subject to review by Integral within a reasonable period
of time prior to the filing thereof. After the Closing Date, Integral and the
Surviving Corporation, on the one hand, and the Shareholders' Representative and
each of the Major Shareholders, on the other hand, will make available to the
other, as reasonably requested in writing, all information, records or documents
relating to the liability for Taxes of the Company for all periods prior to or
including the Closing Date and will preserve such information, records or
documents until the expiration of any applicable statute of limitations or
extensions thereof. The Major Shareholders shall 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. The Major Shareholders and the
Company agree that time is of the essence with respect to collection of the
amounts due with respect to the Tax Refund Claims and that the Shareholder's
Representative shall use its best efforts to cause the filing of the Final Tax
Returns and Tax Refund Claims as soon as possible after the Closing Date and
take all such further actions as may be necessary to cause the collection of
such claims, including without limitation such examinations and appeals to the
appropriate taxing authorities as may be necessary, until final resolution of
the Tax Refund Claims. Integral agrees to provide reasonable assistance in
pursuing the Tax Refund Claims.

         6.6    Registration

                (a)  Subject to the terms and conditions of this Agreement,
Integral shall file a registration statement or a post-effective amendment to an
effective registration statement on Form S-3 (or such other form as may be
reasonably available to Integral) (such registration statement or amendment, a
"S-3") with the SEC:

                     (i)  within 90 days subsequent to the date on which the
Effective Time occurs, which S-3 shall cover the shares representing the Base
Stock Consideration and the Excess Stock Consideration, and

                     (ii) within 10 days subsequent to the date on which shares
of Integral Common Stock are issued under Section 1.6 in connection with the
payment of the Contingent Purchase Price with respect to any Earnout Period,

in each case for the purpose of registering the resale of such shares, pursuant
to the Securities Act, and shall use commercially reasonable efforts to cause
such filed S-3 to become and remain effective for such period as may be
reasonably necessary to effect the resale of such shares of Integral Common
Stock but in no event longer than two years after the date of such issuance.

                (b)  In connection with any S-3 registering securities pursuant
to Section 6.6(a) (the "Registrable Securities"), Integral shall:

                     (i)  prepare and file with the SEC such amendments and
supplements to such S-3 and the prospectus used in connection with such S-3 as
may be necessary to comply

                                       41



with the provisions of the Securities Act with respect to the disposition of
such Registrable Securities;

                    (ii)  furnish such number of prospectuses and other
documents incident thereto, including any amendment of or supplement to the
prospectus, as the Shareholders' Representative may from time to time reasonably
request;

                    (iii) to the extent necessary, use commercially reasonable
efforts to qualify the Registrable Securities for offer and sale under such
other securities or blue sky laws of such jurisdictions in the United States as
the Shareholders' Representative reasonably requests;

                    (iv)  use commercially reasonable efforts to cause all such
Registrable Securities to be listed on the Nasdaq National Market;

                    (v)   pay all reasonable expenses incurred in connection
with such registration, including registration and filing fees with the SEC,
fees and expenses of compliance with securities or blue sky laws, and fees and
expenses incurred in connection with the listing or quotation of the Registrable
Securities; and

                    (vi)  indemnify each Shareholder for any liability such
Shareholder suffers by reason of the filing of such S-3 arising from:

                          (1) any untrue statement of a material fact contained
in such S-3;

                          (2) any omission to state in such S-3 a material fact
required to be stated therein or necessary to make a statement therein, in the
light of the circumstances under which it was made, not misleading; or

                          (3) any violation by Integral of the Securities Act or
any rule or regulation promulgated thereunder applicable to Integral, or of any
blue sky or other state securities laws or any rule or regulation promulgated
thereunder applicable to Integral,

in each case, relating to any action or inaction required of Integral in
connection with such S-3; provided, however, that the foregoing indemnity
obligation shall not be applicable to the extent that such liability is caused
directly or indirectly by information such Shareholder or such Shareholder's
representatives provide or provided to Integral.

               (c)  Notwithstanding anything to the contrary in this Agreement,
Integral may delay the filing of an S-3 if: (i) in the good faith and reasonable
judgment of the Board of Directors of Integral, such registration would be
seriously detrimental to Integral, and the Board of Directors of Integral
concludes, as a result, that it is essential to defer the filing of such S-3 at
such time, and (ii) Integral shall furnish to the Shareholders' Representative a
certificate signed by the Chairman of the Board of Integral stating that in the
good faith judgment of the Board of

                                       42



Directors of Integral, it would be seriously detrimental to Integral for such
S-3 to be filed in the near future and that it is, therefore, essential to defer
the filing of such registration statement; provided, however, that Integral
shall have the right to defer such filing for a period of not more than 90 days,
and, provided further, that Integral shall not defer its obligation in this
manner more than once.

              (d) Upon receipt of any notice from Integral of the happening of
any event which makes any statement made in an S-3 or related prospectus untrue
or which requires the making of any changes in such S-3 or prospectus so that
they will not contain any untrue statement of a material fact or omit to state
any material fact required to be stated therein or necessary to make the
statements therein in light of the circumstances under which they were made not
misleading, each Shareholder shall forthwith discontinue disposition of shares
pursuant to such S-3 until such Shareholder's receipt of the copies of the
supplemented or amended prospectus (which Integral shall use commercially
reasonable efforts to prepare and distribute promptly) or until it is advised in
writing by Integral that the use of the prospectus may be resumed, and has
received copies of any additional or supplemental filings which are incorporated
by reference in the prospectus.

         6.7  Third-Party Consents. Schedule 6.7 contains a list of Material
Contracts for which the written consent of the third party was not obtained
prior to the Closing Date. The Major Shareholders shall use commercially
reasonable efforts to obtain all third-party consents after the Closing.

         6.8  Changes in Integral Common Stock. If, and as often as, there are
any changes in the Integral Common Stock, prior to the Closing, by way of stock
split, stock dividend, combination or reclassification, or through merger,
consolidation, reorganization or recapitalization or by any other means,
appropriate adjustment shall be made in the provisions hereof, as may be
required, so that the rights and privileges granted hereby shall continue with
respect to the Integral Common Stock as so changed.

         6.9  8-K. The Company, its officers and the Major Shareholders agree to
assist Integral, its auditors and counsel in the preparation of a Form 8-K or
Forms 8-K disclosing the transactions contemplated by this Agreement.

Company an Employee Proprietary Information, Inventions and Non-Competition

         6.11 Western National Bank Debt. As soon as reasonably practicable
after the Effective Time, Integral shall take all commercially reasonable
actions necessary to either:

with respect to the Company's line of credit with Western National Bank; or

                                       43



            (b) pay in full all outstanding balances under the Company's line of
credit with Western National Bank, terminate the security interest in the
Company's assets held by Western National Bank in connection with such line of
credit by filing a UCC-3 termination statement with the Colorado Secretary of

      6.12  General. In case at any time, and from time to time, after the
Closing any further action is reasonably necessary or desirable to carry out the
purposes of this Agreement, each of the Parties will take such further action
(including without limitation the execution and delivery of such further
documents, instruments of transfer or assignment, files, books and records) as
any other Party reasonably may request in writing, all at the sole cost and
expense of the requesting Party (unless the requesting Party is entitled to
indemnification therefor under Article 8 below). Each of the Major Shareholders
acknowledges and agrees that from and after the Closing, Integral will be
entitled to possession of all documents, books, records (including without
limitation Tax records), agreements and financial data of any sort relating to
the Company or the Surviving Corporation, copies of which shall be provided to
the Major Shareholders and the Shareholders' Representative upon reasonable
request thereby (provided that each of the Major Shareholders and the
Shareholders' Representative executes a commercially reasonable confidentiality
agreement acceptable to Integral prior to the receipt of such copies).

8.       Remedies for Breaches of This Agreement

         8.1 Survival of Representations and Warranties. All representations,
warranties covenants and agreements of each of the Parties contained in this
Agreement, including those contained in the exhibits, schedules and other
documents delivered pursuant to this Agreement, shall survive the Closing
hereunder and any investigation, audit or inspection at any time made by or on
behalf of any Party hereto and shall continue in full force and effect until
December 31, 2006. Notwithstanding anything herein to the contrary, so long as a
claim arising out of a breach of a representation or warranty or nonperformance
of any agreement or covenant is made prior to the expiration of the applicable
period of survival set forth above with respect to such representation,
warranty, covenant or agreement, such representation, warranty, covenant or
agreement shall survive with respect to such claim until final resolution
thereof and indemnification may be had (subject to the other provisions of this
Section 8) notwithstanding that the scope of loss may not be determined,
remedial work completed or claim otherwise resolved prior to such expiration.

         8.2    Indemnity.

                (a) Subject to the limitations set forth in Section 8.6 and in
accordance with such Shareholder's covenants and agreements in the Shareholder
Representation Agreement or the Investor Agreement (as the case may be), each
Shareholder, severally, shall indemnify and hold Integral, the Merger Sub and
the Surviving Corporation harmless to the extent provided in this Section 8 from
and against any and all losses (consequential or otherwise), Liabilities,
claims, disputes, proceedings, demands, cost unallowability determinations,
judgments, settlements, liens, costs and expenses of any nature whatsoever
(including reasonable fees and disbursements of attorneys, accountants, or other
professional advisors relating to investigation, prosecution, negotiation,
defense, settlement or appeal), but excluding in each such case any such item to
the extent that it is subject to a reserve on the Interim Balance Sheet and
Closing Date Balance Sheet (the foregoing referred to individually as an
"Adverse Consequence" and collectively as "Adverse Consequences") resulting from
or arising out of:

                (i)   any breach of any representation or warranty of the
Company and/or any of the Shareholders contained in this Agreement or in any
schedule, exhibit, certificate, document or other item delivered by the Company
and/or any of the Major Shareholders or their respective representative(s) in
connection with this Agreement;

                (ii)  the nonperformance, partial or total, of any covenant or
agreement of the Company and/or any of the Major Shareholders contained in this
Agreement, except for the nonperformance of a Major Shareholder of his
obligations under Section 9 (for which, together with any and all Adverse
Consequences resulting from or arising out of such non-performance, such Major
Shareholder shall severally be liable); or

                (iii) any and all Adverse Consequences incidental to any of the
foregoing or to the enforcement of this Section 8.2(a).

                                       46



The rights and remedies relating to the Escrow Fund shall be as provided in
Section 8.4. Without limiting the foregoing, the indemnification liabilities of
each of the Shareholders arising from Section 3 of this Agreement (other than
indemnification liabilities relating to the Tax Refund Claims) shall include
Adverse Consequences consisting of any and all Taxes with respect to any period
(or any portion thereof) up to and including the Closing Date, except for Taxes
of the Company (if any) that are reflected as current or deferred liabilities
for Taxes on the Interim Balance Sheet. Each of the Shareholders agrees that it
will not make any claim for indemnification against the Company or the Surviving
Corporation (whether such claim is for judgments, damages, penalties, fines,
costs, amounts paid in settlement, losses, expenses or otherwise and whether
such claim is pursuant to any statute, charter document, bylaw, agreement or
otherwise) with respect to any action, suit, proceeding, complaint, claim, or
demand brought by Integral against any of the Shareholders (whether such action,
suit, proceeding, complaint, claim or demand is pursuant to this Agreement,
applicable law or otherwise). Each Shareholder irrevocably waives any and all
rights to recourse against the Company or the Surviving Corporation with respect
to any misrepresentation or breach of any representation, warranty or indemnity,
or noncompliance with any conditions, covenants or agreements, given or made by
any Major Shareholder or the Company in this Agreement. No Shareholder shall be
entitled to contribution from, subrogation to or recovery against the Company or
the Surviving Corporation with respect to any liability of such Shareholder that
may arise under or pursuant to this Agreement or the transactions contemplated
hereby.

              (b) Integral shall indemnify and hold the Shareholders harmless to
the extent provided in this Section 8 from and against any and all Adverse
Consequences resulting from or arising out of:

                  (i)   any breach of any representation or warranty of Integral
or the Merger Sub contained in this Agreement or in any schedule, exhibit,
certificate, document or other item delivered by Integral or the Merger Sub or
either of their respective representative(s) in connection with this Agreement;

                  (ii)  the nonperformance, partial or total, of any covenant or
agreement of Integral or the Merger Sub contained in this Agreement; or

                  (iii) any and all Adverse Consequences incidental to any of
the foregoing or to the enforcement of this Section 8.2(b).

         8.3  Notice of Claim by the Shareholders.

              (a) If the Shareholders are entitled to indemnification pursuant
to this Agreement and make a claim for indemnification against Integral, such
claim shall be made by the Shareholders' Representative in writing and shall
state in general terms the facts upon which the Shareholders make such claim.

              (b) In the event that any claim or demand is asserted against the
Shareholders by a third party for which the Shareholders may claim
indemnification by Integral, Integral shall

                                       47



give written notice to the Shareholders' Representative within fifteen (15) days
after receipt of notice from the Shareholders' Representative of such claim or
demand indicating whether Integral intends to assume the defense of such claim
or demand. If Integral does assume such defense, it shall indemnify and hold the
Shareholders harmless from and against any and all losses, damages and
liabilities caused by or arising out of any settlement or judgment of such claim
(regardless of any limitations on indemnification set forth herein) and may not
claim that it does not have an indemnification obligation with respect thereto.
Notwithstanding such assumption, the Shareholders' Representative shall have the
right to participate in such defense, by written notice given to Integral within
fifteen (15) days from the date of Integral's notice, provided that such
participation shall be at the expense of the Shareholders unless there is a
conflict of interest (as reasonably determined by the Shareholders'
Representative) between the Shareholders and Integral, in which case the cost of
such participation (including reasonable attorneys' fees for counsel selected by
the Shareholders' Representative) shall be reimbursed by Integral. If Integral
assumes the defense and the Shareholders' Representative elects not to
participate, Integral shall have the right fully to control and to settle the
proceeding. If the Shareholders' Representative elects to participate in such
defense, the Parties shall cooperate in the defense of the proceeding, and shall
not settle the same without the consent of each, which consent shall not be
unreasonably withheld or delayed. If Integral elects not to assume the defense,
the Shareholders' Representative shall have the right to do so (at the expense
of Integral), and may settle the same without the consent of Integral.

               (c) In the event the Shareholders have a claim against Integral
hereunder which does not involve a claim being asserted against or sought to be
collected by a third party, Integral shall give written notice to the
Shareholders' Representative within thirty (30) days after receipt of notice
from the Shareholders' Representative of such claim indicating whether Integral
disputes such claim. If Integral does not notify the Shareholders'
Representative or the Shareholders within such thirty (30) day period that
Integral disputes such claim, the amount of such claim shall be conclusively
deemed a liability of Integral hereunder. In the event that Integral shall
object in writing to any claim made in accordance with this Section 8.3(c), the
Shareholders' Representative and Integral shall attempt in good faith for
fourteen (14) days after receipt of such written objection to agree upon the
rights of the respective Parties with respect to each of such claims. If the
Shareholders' Representative and Integral should so agree, a memorandum setting
forth such agreement shall be prepared and signed by both the Shareholders'
Representative and Integral. If the Shareholders' Representative and Integral
cannot agree within such fourteen (14) day period, the Shareholders'
Representative shall be free to pursue such remedies as may be available to it
under contract or applicable law.

         8.4   Tax Refund Claims Escrow Arrangements.

               (a) Solely as security for the representation and warranty in
Section 3.10 relating to the date of receipt and amount of the Tax Refund
Claims, the Shareholders will be deemed to have received and deposited with
Wachovia Bank (the "Escrow Agent") the Cash Escrow and the Escrow Shares, plus
any cash and/or additional securities that may be issued in connection with any
stock split, reorganization, merger, stock dividend or recapitalization effected
by Integral after the Effective Time with respect to the Escrow Shares and the

                                       48



certificate(s), document(s) or instrument(s) representing or evidencing the
Escrow Shares and such other securities, without any act of any Shareholder.
Such Cash Escrow, Escrow Shares, cash and other securities, as deposited with
the Escrow Agent, shall constitute an escrow fund (the "Escrow Fund") and shall
be governed by the terms set forth in this Section 8.4 and in the Escrow
Agreement (the "Escrow Agreement"), dated as of the Closing Date, among
Integral, the Shareholders' Representative and the Escrow Agent. The amounts
contributed on behalf of each Shareholder to the Escrow Fund is set forth on
Schedule 1.5, which amounts are in proportion to the aggregate Initial Purchase
Price to which such Shareholder would otherwise be entitled under Section 1.5.

               (b) If any amounts are distributed to Integral pursuant to the
Escrow Agreement, Integral shall assign to the Shareholders the right to receive
a portion of any pending Tax Refund Claims that have not been collected by
December 31, 2003 up to the amounts so distributed to Integral.

               (c) Each Shareholder shall have voting rights with respect to the
shares of Integral Common Stock contributed to the Escrow Fund by such
Shareholder and on any other voting securities added to the Escrow Fund pursuant
to Section 8.4(a).

               (d) In all instances in which amounts are distributed to Integral
pursuant to this Section 8.4, such distributions shall be in cash and shares of
Integral Common Stock and the proportion of each shall, as nearly as possible,
be in proportion to the Escrow Cash and Escrow Shares originally contributed to
the Escrow Fund. For purposes of determining the number of Escrow Shares to be
delivered in connection with the preceding sentence to satisfy the
indemnification obligations of the Shareholders pursuant to this Section 8.4,
the per share value of the Escrow Shares shall be deemed to be, for purposes of
this Section 8.4, the Average Price) (subject to adjustment for any stock split,
stock dividend or other change with respect to the Integral Common Stock).

         8.5    Set-Off Rights.

               (a) Notwithstanding anything herein to the contrary, each of the
Shareholders agrees that Integral shall have the right, but not the obligation,
to set-off against the Contingent Purchase Price the full amount of any Adverse
Consequences required to be paid by the Shareholders pursuant to this Article 8.

               (b) With respect to the right to set-off under Section 8.5(a),

                   (i)  Integral shall initially have the right to set-off
against the full amount of the Contingent Purchase Price;

                   (ii) beginning immediately after the Contingent Purchase
Price with respect to "Earnout Period 1" (identified on Schedule 1.6) is paid to
the Shareholders, Integral shall have the right to set-off against any unpaid
Contingent Purchase Price but not against any

                                       49



amount of the Contingent Purchase Price which was paid to the Shareholders with
respect to Earnout Period 1;

         (iii) beginning immediately after the Contingent Purchase Price with
respect to "Earnout Period 2" (identified on Schedule 1.6) is paid to the
Shareholders, Integral shall have the right to set-off against any unpaid
Contingent Purchase Price but not against any amount of the Contingent Purchase
Price which was paid to the Shareholders with respect to Earnout Period 1 or
Earnout Period 2;

         (iv)  beginning immediately after the Contingent Purchase Price with
respect to "Earnout Period 3" (identified on Schedule 1.6) is paid to the
Shareholders, Integral shall have the right to set-off against any unpaid
Contingent Purchase Price but not against any amount of the Contingent Purchase
Price which was paid to the Shareholders with respect to Earnout Period 1,
Earnout Period 2 or Earnout Period 3; and

         (v)   beginning immediately after the Contingent Purchase Price for
"Earnout Period 4" (as identified on Schedule 1.6) is paid to the Shareholders,
Integral shall have no further right to set-off (except with respect to any
unpaid Contingent Purchase Price).

     (c) If Integral elects to exercise its set-off rights hereunder, it will
give the Shareholders' Representative written notice of such election, which
shall include the amount to be set-off and a description of the factual basis
for such set-off, and upon giving such notice, the Contingent Purchase Price
shall automatically be reduced by the amount set forth in such notice. Any
set-off pursuant to this Section 8.5 shall be deemed to be final, binding and
not subject to appeal other than as set forth herein. In the event that the
Shareholders' Representative shall object in writing to any such notice of
set-off hereunder within fifteen (15) days of receipt thereof, and such
objection contains a specific request for limited and readily-accessible
information in the possession of Integral that was previously prepared solely to
determine the amount of such set-off, Integral shall make a reasonable effort to
make available such information to the Shareholders' Representative (provided
that the Shareholders' Representative executes a commercially reasonable
confidentiality agreement acceptable to Integral prior to the receipt of such
information), and the Shareholders' Representative and Integral shall attempt in
good faith for fourteen (14) days after receipt of such written objection to
agree upon the rights of the respective Parties with respect to each of such
claims. If the Shareholders' Representative and Integral should so agree, a
memorandum setting forth such agreement shall be prepared and signed by the
Shareholders' Representative and Integral. If the Shareholders' Representative
and Integral cannot agree within such fourteen (14) day period, the
Shareholders' Representative shall be free to pursue such remedies as may be
available to it under contract or applicable law. In the event there is a final
determination by a court of competent jurisdiction that Integral was not
entitled to indemnification under this Section 8.5(b) with respect to any
set-off amount, Integral shall promptly thereafter deliver to the Shareholders'
Representative all such amounts which are so determined to have been incorrectly
set-off, together with reasonable fees and disbursements of attorneys,
accountants and other professional advisors relating to such determination
incurred by the Shareholders' Representative.

                                       50



     8.6   Limitation.

           (a)   The rights of Integral in the Escrow Fund set forth in
Section 8.4 shall be the sole remedy available to Integral with respect to the
representation and warranty in Section 3.10 relating to the date of receipt and
amount of the Tax Refund Claims.

           (b)   Except with respect to any knowing and intentional or
fraudulent breaches of the representations, warranties, agreements or covenants
of the Company or the Major Shareholders contained in this Agreement, the sole
and exclusive remedy available to Integral pursuant to the indemnity set forth
in Section 8.2(a) shall be the right of set-off set forth in Section 8.5. The
Parties agree that the right to indemnity under Section 8.2 and this Section 8.6
shall include the right of Integral to be indemnified for any Adverse
Consequences relating to Taxes or Tax Returns, except with respect to the
representation and warranty in Section 3.10 relating to the date of receipt and
amount of the Tax Refund Claims.

           (c)   Notwithstanding the above, the aggregate amount of the
liability of Integral under this Article 8 shall not exceed an amount equal to
the Contingent Purchase Price.

           (d)   Except as otherwise set forth in this Agreement, this Article 8
sets forth the sole exclusive remedy and recourse of the Parties for monetary
damages arising from any claim, cause of action or right of any nature under
this Agreement; provided, however, that nothing contained in this Article 8
shall be in lieu of, or constitute a waiver of, any remedies in equity that any
Party may otherwise have.

9.   NONCOMPETITION

     9.1   Prohibited Activities. Each of the Major Shareholders (each, a
"Non-Competing Party") acknowledges that, in connection with the transactions
contemplated by this Agreement, such Non-Competing Party will be exposed to and
gain information concerning Integral and its operations, including confidential
and proprietary information, and concerning clients and prospective clients of
Integral, and that it would cause severe harm to Integral if such Non-Competing
Party used such information to compete with or assist another person, company or
entity in competing with Integral. Each Non-Competing Party agrees that until
the end of the two (2) year period beginning on the Closing Date it will not,
either for itself or as a shareholder, partner, investor, consultant, contractor
or agent or in any other capacity:

           (a)   Engage in any business, activity or work that is in any way
competitive with the business of Integral within the continental United States.

           (b)   Perform any services in the fields of tracking stations,
telemetry processing, and/or satellite command and control, sell, solicit or
attempt to sell any products and/or services in the fields of tracking stations,
telemetry processing, and/or satellite command and control to, or interfere with
Integral's relationship with any person, company or other entity that was a
customer of Integral or was identified by Integral as a prospective customer
during the period that such Non-Competing Party was an affiliate or shareholder
of Integral. For purposes

                                       51



of this Article 9, "customer" means all persons, firms or entities that have
either (1) sought or obtained Integral's services, (2) contacted Integral for
the purpose of providing its services or (3) been contacted by Integral for the
purpose of providing its services, and all persons, firms or entities subject to
control of those persons, firms or entities.

                (c)   Solicit, hire or employ, or cause any other person,
company or entity to solicit, hire or employ any employee or contractor retained
or employed by Integral.

                (d)   Disparage Integral to anyone outside of Integral,
including without limitation competitors, customers and potential customers, or
to employees or potential employees of Integral.

As used in this Agreement, "business of Integral" and "Integral's business"
includes building satellite ground systems for command and control, integration
and test, data processing, and simulation, including science, meteorology and
earth resource applications; building communication system monitor systems for
satellite owners, operators and users; and building products and/or providing
services in the fields of tracking stations, telemetry processing, and/or
satellite command and control.

         Notwithstanding the above, the foregoing covenant shall not be deemed
to prohibit any Non-Competing Party from acquiring as an investment not more
than one percent (1%) of the capital stock of a competing business whose stock
is traded on a national securities exchange or over-the-counter. For purposes of
this Article 9, the term "Integral" includes Integral, the Company (both prior
to and after the Merger), the Surviving Corporation and all subsidiaries of
Integral.

         9.2    Damages. Because of the difficulty of measuring economic losses
to Integral as a result of a breach of the covenants contained in this Section
9, and because of the immediate and irreparable damage that could be caused to
the Company, the Surviving Corporation and/or Integral for which the Company,
the Surviving Corporation and/or Integral would have no other adequate remedy
(and for which monetary damages would not be sufficient), each Non-Competing
Party agrees that, in addition to any and all other remedies that may be
available to the Company, the Surviving Corporation and/or Integral at law or in
equity (which such remedies, notwithstanding Section 8.6, shall be available to
the Company, the Surviving Corporation and/or Integral), the covenants contained
in this Section 9 may be enforced by the Company, the Surviving Corporation
and/or Integral in the event of breach by such Non-Competing Party, by
injunctions and restraining orders or other equitable relief. Notwithstanding
anything herein to the contrary, the liability of each Non-Competing Party
hereunder for damages shall only be in respect of a breach of this covenant by
such Non-Competing Party.

         9.3    Reasonable Restraint. The Parties agree that the foregoing
covenants in this Article 9 impose a reasonable restraint on each Non-Competing
Party in light of the activities and business of Integral on the date of the
execution of this Agreement and the current plans of Integral; but it is also
the intent of Integral and each Non-Competing Party that such covenants be
construed and enforced in accordance with the changing activities and business
of Integral

                                       52



throughout the term of this covenant. The Parties further agree that in the
event any Non Competing Party shall enter into a business or pursue other
activities not in competition with Integral or similar activities or business in
locations the operation of which, under such circumstances, does not violate
Section 9.1(a), such Non-Competing Party shall not be chargeable with a
violation of this Article 9 if Integral shall thereafter enter the same, similar
or a competitive (a) business, (b) course of activities or (c) location, as
applicable.

         9.4 Severability; Reformation. The covenants in this Article 9 are
severable and separate, and the unenforceability of any specific covenant or
portion thereof shall not affect the other portions of such covenant or the
provisions of any other covenant. Moreover, in the event any court of competent
jurisdiction shall determine that the scope, time or territorial restrictions
set forth are unreasonable, then it is the intention of the Parties that such
restrictions be enforced to the fullest extent which the court deems reasonable,
and the Agreement shall thereby be reformed.

         9.5 Independent Covenant. All of the covenants in this Article 9 shall
be construed as an agreement independent of any other provision in this
Agreement, and the existence of any claim or cause of action of any
Non-Competing Party against Integral, whether predicated on this Agreement or
otherwise, shall not constitute a defense to the enforcement by Integral of such
covenants. It is specifically agreed that the period of two (2) years stated at
Section 9.1, during which the agreements and covenants of each Non-Competing
Party made in this Article 9 shall be effective, shall be computed by excluding
from such computation any time during which any such Non-Competing Party is
found by a court of competent jurisdiction to have been in violation of any
provision of this Article 9. The covenants contained in Article 9 shall not be
affected by any breach of any other provision hereof by any party hereto and
shall have no effect if the transactions contemplated by this Agreement are not
consummated.

         9.6    Materiality. Each Non-Competing Party hereby agrees that the
covenants set forth in this Article 9 are a material and substantial part of the
transactions contemplated by this Agreement.

10.      GENERAL

         10.1   Shareholders' Representative.

                (a) Approval of the Merger by the Shareholders shall also
constitute the appointment of Randal E. Culver to act as representative of the
Shareholders and to act as each of the Shareholder's attorney-in-fact and
representative (the "Shareholders' Representative"), to do any and all things
and to execute any and all documents, in such party's name, place and stead, in
any way which such party could do if personally present, in connection with each
Shareholder Representation Agreement and Investment Agreement and this Agreement
and the transactions contemplated hereby, including without limitation to amend,
cancel or extend, or waive, any of the terms of any such Shareholder
Representation Agreement and Investment Agreement and this Agreement or to
receive any notice required hereunder or thereunder. Approval of the Merger by
the Shareholders shall also constitute the approval of the provision of the sum
of $10,000 out of

                                       53



the Base Cash Purchase Price (which shall be allocated among the Shareholders
pro rata (based on the number of shares of Company Common Stock held by the
Shareholders at the Closing of the Merger)) to cover expenses of performance of
the duties of the Shareholders' Representative hereunder and under each
Shareholder Representation Agreement and Investment Agreement. Integral, Merger
Sub and the Surviving Corporation shall be entitled to rely, as being binding
upon such Shareholders, upon any document or other paper believed by Integral,
the Merger Sub or the Surviving Corporation to be genuine and correct and to
have been signed by the Shareholders' Representative, and Integral, the Merger
Sub and the Surviving Corporation shall not be liable to any Shareholder for any
action taken or omitted to be taken by Integral, the Merger Sub or the Surviving
Corporation in such reliance. The Shareholders' Representative shall have the
sole and exclusive right on behalf of any Shareholder to take any action or
provide any waiver, or receive any notice, pursuant to Articles 8 and 9 and
Sections 1.6(d), 10.10 and 10.16 of this Agreement and to settle any claim or
controversy arising under this Agreement or any Shareholder Representation
Agreement or Investment Agreement.

                  (b) The Shareholders' Representative may resign at any time by
giving written notice of resignation, at least sixty (60) days prior to such
resignation, to Integral, the Surviving Corporation and the Shareholders, and
the Shareholders' Representative may be removed at any time with or without
cause by upon the approval of two-thirds in interest (based on the number of
shares of Company Common Stock held by the Shareholders on the Closing Date) of
the Shareholders (collectively, the "Approving Shareholders"). Upon any such
resignation or removal, such Approving Shareholders shall select a successor
Shareholders' Representative, which successor shall be approved by the Approving
Shareholders. In the case of a resigning Shareholders' Representative, if no
successor Shareholders' Representative shall have been so appointed by the
Approving Shareholders and shall have accepted such appointment (effective upon
the date of resignation of the resigning Shareholders' Representative), within
thirty (30) days after the retiring Shareholders' Representative's giving of
notice of resignation, then the retiring Shareholders' Representative (or
Integral if the retiring Shareholders' Representative does not act) may, on
behalf of the Approving Shareholders, appoint a successor Shareholders'
Representative. Upon the acceptance of any appointment as Shareholders'
Representative thereunder by a successor Shareholders' Representative, such
successor Shareholders' Representative shall thereupon succeed to and become
vested with all the rights, powers, privileges and duties of the retiring
Shareholders' Representative, and the retiring Shareholders' Representative
shall be discharged from its duties and obligations as Shareholders'
Representative under this Agreement and under each Shareholder Representation
Agreement and Investment Agreement. After any retiring Shareholders'
Representative's resignation or removal hereunder as Shareholders'
Representative, the provisions of this Section 10.1 shall inure to its benefit
as to any actions taken or omitted to be taken by it while it was Shareholders'
Representative.

                   (c) The grant of authority provided for in this Section 10.1:
(a) is coupled with an interest and shall be irrevocable and survive the death,
incompetency, bankruptcy or liquidation of any Shareholder and shall be binding
on any successor thereto and (b) shall survive the delivery of an assignment by
any Shareholder of the whole or any fraction of its interest in any payment due
to it under this Agreement.

                                       54



                   (d) The duties and responsibilities of the Shareholders'
Representative hereunder shall be determined solely by the express provisions of
this Agreement, and no other or further duties or responsibilities shall be
implied under this Agreement or any other agreement among the parties hereto,
whether or not the Shareholders' Representative has knowledge thereof. The
Shareholders acknowledge that the Shareholders' Representative is acting solely
as a stakeholder at the request of, and for the convenience of, the
Shareholders, that the Shareholders' Representative shall not be deemed to be
the agent of the Company or the Shareholders (except, in the case of the
Shareholders, as contemplated hereunder and under each Shareholder
Representation Agreement and Investment Agreement), and that the Shareholders'
Representative shall be released and exculpated of all liability whatsoever
arising from, related to, in connection with or resulting from its activities as
Shareholders' Representative and shall not be liable to the Company or the
Shareholders for any act or omission on its part, unless taken, not taken or
suffered in bad faith or in willful disregard of this Agreement or involving
gross negligence or willful misconduct on the part of the Shareholders'
Representative.

                  (e) Except as otherwise contemplated hereunder or under any
Shareholder Representation Agreement or Investment Agreement, the Shareholders'
Representative shall be entitled to rely, as being binding upon each
Shareholder, upon any document or other paper believed by the Shareholders'
Representative to be genuine and correct and to have been signed by such
Shareholder, and the Shareholders' Representative shall not be liable to any
Shareholder for any action taken or omitted to be taken by the Shareholders'
Representative in such reliance.

                   (f) The Shareholders agree that they shall indemnify the
Shareholders' Representative in an amount and of such character as the
Shareholders' Representative shall reasonably require to institute or defend any
action or legal proceeding involving any matter referred to in this Agreement,
including any and all claims, losses, liabilities, costs, judgments, attorneys'
fees and other expenses of every kind and nature whatsoever in relation thereto.

                  (g) Except as otherwise contemplated hereunder, the
Shareholders' Representative shall not be liable to the Shareholders for any
action taken or not taken by it in good faith and believed by it to be
authorized by, or within the rights or powers conferred upon it by, this
Agreement and may consult with counsel of its own choice and shall have full and
complete authorization and protection for any action taken, not taken or
suffered by it hereunder in good faith and in accordance with, or in reliance
upon, the opinion or advice of such counsel.

                  (h) The Shareholders hereby agree to pay or reimburse the
Shareholders' Representative upon request for all expenses, disbursements and
advances, including reasonable attorney's fees, incurred or made by the
Shareholders' Representative in connection with the carrying out of its duties
hereunder, which payment or reimbursement shall not exceed each such
Shareholder's pro rata portion (based on the number of shares of Company Common
Stock held by the Shareholders at the Closing of the Merger), unless such
Shareholder has committed fraud and such fraud has given rise to such expenses
or amounts.

                                       55



              (i)   The parties hereto agree that neither Integral, the
Surviving Corporation nor the Merger Sub shall be liable for any action taken or
not taken by the Shareholders' Representative hereunder. Each of the
Shareholders and the Shareholders' Representative agree that all disputes,
controversies or other matters arising between or among the Shareholders and the
Shareholders' Representative, and any and all liabilities with respect to such
disputes, controversies or other matters, shall be limited to such parties
solely, and that neither Integral nor any other party shall have any
responsibility or liability whatsoever with respect to such disputes,
controversies or other matters.

         10.2 Shareholders. Each Shareholder, by its acceptance of any portion
of the Purchase Price or its rights to receive such portion of the Purchase
Price, shall be deemed to have accepted and agreed to each and every term of
this Agreement applicable to the Shareholders and/or the Parties generally,
including without limitation the provisions applicable to the Shareholders under
Article 8 (Remedies for Breaches of this Agreement) and Sections 10.1 and 10.10.

         10.3 Cooperation. Each of the Major Shareholders, on the one hand, and
Integral, on the other hand, for no further consideration, shall each deliver or
cause to be delivered to the other on the Closing Date, and either before or
after the Closing Date at such other times and places as shall be reasonably
agreed to, such additional instruments as the other may reasonably request for
the purpose of carrying out this Agreement. Each of the Major Shareholders will
cooperate and use its reasonable best efforts to have the present officers,
directors and employees of the Company cooperate with Integral on and after the
Closing Date in furnishing information, evidence, testimony and other assistance
in connection with any Tax Return filing obligations, actions, proceedings,
arrangements or disputes of any nature with respect to matters pertaining to all
periods prior to the Closing Date.

         10.4 Successors and Assigns. This Agreement and the rights of the
Parties hereunder may not be assigned, including without limitation assignments
by operation of law or otherwise, without the written consent of the other
Parties and shall be binding upon and shall inure to the benefit of the Parties
hereto and their respective permitted assigns, the successors of Integral, and
the successors of the Major Shareholders.

         10.5 Entire Agreement. This Agreement (which includes the Schedules and
Exhibits hereto) sets forth the entire understanding of the Parties hereto with
respect to the transactions contemplated hereby. This Agreement (including
without limitation this Section 10.5) shall not be amended or modified except as
set forth in Section 10.16. Any and all previous agreements and understandings
between or among the Parties regarding the subject matter hereof, whether
written or oral, are superseded by this Agreement.

         10.6 Counterparts. This Agreement may be executed in any number of
counterparts and any Party may execute any such counterpart, each of which when
executed and delivered shall be deemed to be an original and all of which
counterparts taken together shall constitute but one and the same instrument.
This Agreement shall become binding when one or more counterparts taken together
shall have been executed and delivered (which deliveries may be by telefax) by
the Parties.

                                       56



         10.7  Brokers and Agents. Integral, on the one hand, and each of the
Major Shareholders, on the other hand, represents and warrants to the other that
it has not employed any broker or agent in connection with the transactions
contemplated by this Agreement and agrees to indemnify the other against all
loss, damages or expense relating to or arising out of claims for fees or
commission of any broker or agent employed or alleged to have been employed by
such indemnifying party, except as set forth on Schedule 3.24.

         10.8  Expenses. Subject to Sections 8 and 10.10, each party to this
Agreement shall bear and pay all fees, costs and expenses (including legal fees
and accounting fees) that have been incurred or that are incurred in the future
by such party in connection with the transactions contemplated by this
Agreement, including all fees, costs and expenses incurred by such party in
connection with or by virtue of (a) the negotiation, preparation and review of
this Agreement (including any schedules and exhibits) and all agreements,
certificates, opinions and other instruments and documents delivered or to be
delivered in connection with the transactions contemplated by this Agreement and
(b) the preparation and submission of any filing or notice required to be made
or given in connection with any of the transactions contemplated by this
Agreement, and the obtaining of any consent required to be obtained in
connection with any of such transactions; provided, however, that the fees and
expenses incurred by or on behalf of the Company (the "Legal Fees") shall be
reasonable. Notwithstanding anything herein to the contrary, in computing the
Pre-Tax Earnings for any "Earnout Periods" set forth on Schedule 1.6, such
Pre-Tax Earnings shall be reduced by an amount equal to the Legal Fees paid
after the Closing Date and during such Earnout Period.

approval or other communication which is required or permitted hereunder shall

         10.10 limited Arbitration.

               (a) The Parties agree that all disagreements or disputes with
respect to any accounting matters in connection with determining Pre-Tax
Earnings shall be resolved in accordance with Sections 10.10(b) and (c).
Further, the Parties agree to submit all disputes and disagreements with respect
to determining the accuracy of the Financial Statements and Closing Date Balance
Sheet of the Company to arbitration conducted in the manner set forth in Section
10.10(c) below.

                                       58



               (b)  In the event that the Shareholders' Representative disagrees
with any Earnout Report delivered pursuant to Section 1.6 hereof with respect to
any accounting matters (other than with respect to the accounting procedures and
practices reflected therein), the Shareholders' Representative shall deliver to
Integral, within ten (10) days after the initial delivery by Integral of such
Earnout Report, a written notice specifying the matters as to which the
Shareholders' Representative objects with respect to such Earnout Report and the
basis for such disagreement (together with any authority or documentation
supporting the position of such Shareholders' Representative) (such notice, an
"Objection Notice"). If the Shareholders' Representative timely delivers to
Integral an Objection Notice, Integral shall make available to the Shareholders'
Representative the balance sheet and the income statement with respect to the
period covered by the Earnout Report, together with such other documentation as
the Shareholders' Representative reasonably requests to determine the validity
of the Earnout Report, subject to such Objection Notice (provided that the
Shareholders' Representative executes a commercially reasonable confidentiality
agreement acceptable to Integral prior to the receipt of such information), and
Integral and the Shareholders' Representative shall thereupon endeavor in good
faith to resolve the disagreement set forth in the Objection Notice. In the
event such parties do so, such parties shall promptly execute a document which
sets forth resolution of such disagreement, which document shall be binding upon
all Shareholders. In the event that Integral timely receives an Objection Notice
with respect to any specific Earnout Report and the Shareholders' Representative
and Integral are unable to resolve the disagreement specified in the Objection
Notice within fourteen (14) days after initial delivery of the Objection Notice,
both Integral and the Shareholders' Representative agree to submit the dispute
to arbitration conducted in the manner set forth in Section 10.10(c) below.

               (c)  Arbitration pursuant to this Section 10.10 shall be
conducted before a panel of three (3) arbitrators, all residents of Washington
D.C. and licensed practicing accountants, one arbitrator chosen by the
Shareholders' Representative and one by Integral and the third chosen by the two
appointed, all of which shall be chosen within seven (7) days from the
expiration of the fourteen (14) day amicable negotiation period. Both Integral
and the Shareholders' Representative shall submit written claims to the arbital
panel within seven (7) days of its appointment and the hearing shall commence
fifteen (15) days after the selection of the arbital panel, and the arbital
panel shall render its decision within five (5) days after commencement of the
hearing. Any arbitration conducted pursuant to the terms of this Agreement shall
be governed by Maryland law. The arbitrators shall be compensated at their
normal hourly rates, and the costs for the performance of their duties shall be
borne by the non-prevailing party as designated by the arbital panel. Integral,
the Shareholders' Representative and the Shareholders agree to accept and be
bound as final by the decision of the arbitrators, with no right of appeal, and
such decision shall be binding upon all Shareholders. The arbitrators shall be
instructed to make a final decision and shall designate the prevailing party,
who shall be entitled, in addition to all other relief, to an award of
reasonable attorneys' fees, costs and other expenses incurred in connection with
the arbitration. Judgment on the arbitrators' award may be entered in any court
having jurisdiction. Integral, the Shareholders' Representative and the
Shareholders agree to waive any objections based on jurisdiction and agree to
submit to the jurisdiction of any properly authorized judicial body required to
enforce the judgment of the arbitrators.

                                       59



         10.11  Governing Law; Venue. This Agreement shall be governed by and
construed, interpreted and enforced in accordance with the laws of the State of
Maryland, without regard to conflicts of laws provisions. Except as set forth in
Section 10.10, each Party irrevocably consents and agrees to the exclusive
jurisdiction of the courts of Prince Georges, Maryland or the United States
District Court for the District of Maryland, as well as to the jurisdiction of
all courts to which an appeal may be taken from such courts, for resolution of
all matters involving this Agreement or the transactions contemplated hereby.
Except as set forth in Section 10.10, each Party expressly waives all rights to
bring suit, action or other proceeding in or before any court or tribunal not
subject to the jurisdiction of the above courts. Each Party expressly waives any
and all objections it may have to venue, including, without limitation, the
inconvenience of such forum, in any such courts.

         10.12  Severability. If any provision of this Agreement (or portion
thereof) or the application thereof to any person or circumstances is held
invalid or unenforceable in any jurisdiction, the remainder hereof, and the
application of such provision (or portion thereof) to such person or
circumstances in any jurisdiction, shall not be affected thereby, and to this
end the provisions of this Agreement shall be severable. The preceding sentence
is in addition to and not in place of the severability provisions in Section
9.4.

         10.13  Absence of Third-Party Beneficiary Rights. Unless otherwise
provided herein, no provision of this Agreement is intended, nor will be
interpreted, to provide or to create any third-party beneficiary rights or any
other rights of any kind in any client, customer, affiliate, shareholder,
member, employee or partner of any party hereto or any other person or entity.
The Shareholders are third-party beneficiaries of this Agreement.

         10.14  Mutual Drafting. This Agreement is the mutual product of the
Parties hereto, and each provision hereof has been subject to the mutual
consultation, negotiation and agreement of each of the Parties, and shall not be
construed for or against any Party hereto.

         10.15  Further Representations. Each Party to this Agreement
acknowledges and represents that it has been represented by its own legal
counsel in connection with the transactions contemplated by this Agreement, with
the opportunity to seek advice as to its legal rights from such counsel. Each
party further represents that it is being independently advised as to the tax
consequences of the transactions contemplated by this Agreement and is not
relying on any representation or statements made by the other Party(ies) as to
such tax consequences.

         10.16  Amendment; Waiver. This Agreement may be amended only by
execution of an instrument in writing signed on behalf of each of Integral and
the Merger Sub, on the one hand, and the Major Shareholders and the
Shareholders' Representative, on the other hand. Any waiver by any party of any
provision hereto shall be valid only if set forth in an instrument in writing
signed on behalf of the party waiving such provision.

         10.17  Public Disclosure. Neither the Company nor any of the Major
Shareholders shall make any disclosure (whether or not in response to an
inquiry) of the subject matter of this Agreement unless previously approved by
Integral in writing or as required by law. Integral

                                       60



agrees to keep the Major Shareholders apprised in advance of any disclosure of
the subject matter of this Agreement by Integral.

         10.18  Pronouns. All pronouns contained herein, and any variations
thereof, shall be deemed to refer to the masculine, feminine or neutral,
singular or plural, as the identity of the parties hereto may require.

[                 (                                      {      })]
[EarnoutPercent x ({lesser of Pretax Earnings or Plan} - { Plan })]  + [Pretax Earnings - Plan]
[                 (                                      { ---- })]
[                 (                                      {   2  })]

III.     Limitations to the Results from the Formula

Section 1.6(c) of the Merger Agreement provides additional restrictions to the
results obtained from the formula.

In addition, in the event that either of the following two values are less than
zero, then whichever is less than zero, it shall be deemed equal to zero for
purposes of computing the formula for each Earnout Period:

         (                                      {      })]
         ({lesser of Pretax Earnings or Plan} - { Plan })]
         (                                      { ---- })]
         (                                      {   2  })]

or
