<PAGE>

Financial Statements are correct and complete, and are consistent with the
Company's books and records (which books and records are correct and complete in
all material respects). Since the Interim Balance Sheet Date, there have been no
material changes in the Company's accounting policies. The Company has
adequately reserved on the Interim Balance Sheet against any liabilities of the
Company with respect to any Company warranties and Year 2000 Compliance (as
defined below). For purposes hereof, "Year 2000 Compliance" means that products
(including existing products and technology and products and technology
currently under development) accurately record, store, process, calculate and
present calendar dates falling on and after (and if applicable, spans of time
including) January 1, 2000, and calculate any information dependent on or
relating to such dates in the same manner, and with the same functionality, data
integrity and performance, as the products recorded, stored, processed,
calculated and presented calendar dates on or before December 31, 1999, or
calculated any information dependent on or relating to such dates.

     3.9  Liabilities and Obligations.
          ---------------------------

          (a)  The Company has no liabilities, except for liabilities:

paid or discharged;

               (ii)  those liabilities incurred since the Interim Balance Sheet
Date in the ordinary course of business consistent with past practice, which
liabilities are not, individually or in the aggregate, material;

               (iii) set forth on Schedule 3.9; or
                                  ------------

For purposes of this Section 3.9, the term "liabilities" shall include without
limitation any direct or indirect liability, indebtedness, guaranty,
endorsement, claim, loss, damage, deficiency, cost, expense, obligation or
responsibility, either accrued, absolute, contingent, mature, unmature or
otherwise and whether known or unknown, fixed or unfixed, inchoate or not,
liquidated or unliquidated, secured or unsecured.

          (b)  In the case of those liabilities which are not fixed or
contested, a reasonable estimate of the maximum amount which may be payable is
attached hereto as Schedule 3.9.
                   -------------

     3.10 Accounts and Notes Receivable. The receivables, including unbilled
          -----------------------------
accounts receivables, shown on the Interim Balance Sheet arose in the ordinary
course of business and have been collected or are collectible in the book
amounts thereof, less an amount not in excess of the allowance for doubtful
accounts provided for in such balance sheet. Allowances for doubtful accounts
and warranty returns are adequate and have been prepared in accordance with GAAP
consistently applied and in accordance with the past practices of the Company.

<PAGE>

receivables of the Company arising after the Interim Balance Sheet Date arose in
the ordinary course of business and have been collected or are collectible in
the book amounts thereof, less allowances for doubtful accounts and warranty
returns determined in accordance with the past practices of the Company. None of
the receivables of the Company is subject to any claim of offset, recoupment,
set off or counterclaim and neither the Company nor the Shareholder has
knowledge of any facts or circumstances (whether asserted or unasserted) that
could give rise to any such claim. No amount of receivables is contingent upon
the performance by the Company of any obligation or contract. No person has any
lien on any of such receivables and no agreement for deduction or discount has
been made with respect to any of such receivables.

     3.11 Governmental Permits and Licenses. The Company owns or holds all
          ---------------------------------

titles (including, without limitation, motor vehicle titles and current

approvals, variances, rules and regulations and is not in violation of any of
the foregoing, except where the failure to so conduct its business would not
have a material adverse effect on such Material Permits. The transactions
contemplated by this Agreement will not result in a default under or a breach or
violation of, or adversely affect the rights and benefits afforded to the
Company by any Material Permit.

     3.12 Environmental Matters.  Except as set forth on Schedule 3.12:

improvements thereon) by the Company, as set forth on Schedule 3.13(b), in
                                                      ----------------

businesses or against the Shareholder with respect to the Company under
applicable Environmental Laws. Neither the Shareholder nor the Company has
received any written notice that there is an action, suit, proceeding, claim,
arbitration or investigation pending against the Company or the Shareholder with
respect to the Company under applicable Environmental Laws. To the knowledge of
the Company and the Shareholder, no such action, suit, proceeding, claim,
arbitration or investigation under applicable Environmental Laws is threatened
against the Company or the Shareholder with respect to the Company. Neither the
Company nor the Shareholder have received any written notice or has knowledge of
any past or present condition or practice of the businesses conducted by the
Company which forms or could be reasonably expected to form the basis of any
material claim, action, suit, proceeding, hearing or investigation (collectively
"Environmental Claims") against the Company (or against any person or entity
whose liability for any Environmental Claims the Company has retained or assumed
either contractually or by operation of law), arising out of the manufacture,

purported to be shown therein. The Company prepared such projections in good
faith based upon reasonable assumptions, and the Company and the Shareholder
believe that there is a reasonable basis for such projections. The Company and
the Shareholder are not aware of any fact or information that would lead them to
believe that the Financial Projections are misleading in any material respect.

(or would constitute a default but for any requirement of notice or lapse of
time or both) 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
properties of Merger Sub pursuant to any agreement, contract, note, mortgage,
indenture, lease, sublease, instrument, permit, concession, franchise or license
to which Merger Sub is a party or by which Merger Sub or any of its property or
assets may be bound or affected; or

               (iii)  conflict with or result in a violation of any law,
statute, order, judgment, rule, regulation, decree or ordinance applicable to
Merger Sub or by which any of its properties or assets is bound or affected.

     4.9  Government Contracts.

          (a)  Subsequent to Closing, Integral intends to continue performance
of the Government Contracts set forth on Schedule 3.14(k) by the entity that
                                         ----------------
performed such contracts prior to Closing.

          (b)  Integral further represents that the party to whom the Government
Contracts set forth on Schedule 3.14(k) were awarded will continue to control
                       ----------------
the assets necessary to perform the contracts.

                                       28
<PAGE>

           (c)  Integral intends to continue financing the Government Contracts
set forth on Schedule 3.14(k) in the same manner as they have been previously
             ----------------
financed.

           (d)  Integral intends to utilize essentially the same work force in
the performance of the Government Contracts set forth on Schedule 3.14(k).
                                                         ----------------

           (e)  Integral's representations and warranties pursuant to this
Section 4.9 are designed to qualified for an exemption for the need for a
Novation Agreement as defined in the Assignment of Claims Act found at 41 U.S.C.
Section 15. Notwithstanding anything herein to the contrary, the representations
and warranties made by Integral in this Section 4.9 are subject to the
assumption that (i) the Company performed the Government Contracts set forth on
Schedule 3.14(k) prior to Closing, (ii) the Company was awarded such Government
----------------
Contracts, and (iii) the Company has disclosed to Integral complete and correct
information regarding the financing and work force with respect to such
Government Contracts.

                  (b) The Shareholder 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 and Integral, such as lists of

valuable, special and unique assets of the Company's and Integral's respective
businesses. The Shareholder agrees that he will not disclose Confidential
Information with respect to the Company or Integral to any person, firm,
corporation, association or other entity for any purpose or reason whatsoever,
except to authorized representatives of Integral and to counsel and other

Shareholder, (ii) disclosure is required by law or the order of any Governmental
Authority under color of law, or (iii) the disclosing party reasonably believes

with the opportunity to contest such disclosure.

                  (c) Integral 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, such as lists of customers, operational

assets of the Company's business. Integral agrees that, prior to the Closing, it
will not disclose confidential information with respect to the Company to any
person, firm, corporation, association or other entity for any purpose or reason
whatsoever, except to authorized representatives of the Company and the
Shareholder and to counsel and other advisers, and that it will not disclose
confidential information with respect to the Shareholder to any person, firm,
corporation, association or other entity for any purpose or reason whatsoever,
except to authorized representatives of the Company and the Shareholder and to
counsel and other advisers; provided, however, that such advisers (other than
counsel) agree to the confidentiality provisions of this Section 5.5(c), unless
(i) such information becomes known to the public generally through no fault of
Integral, (ii) disclosure is required by law or the order of any Governmental
Authority under color of law, or (iii) the disclosing party reasonably believes
that such disclosure is required in connection with the defense of a lawsuit
against the disclosing party; and provided further, that prior to disclosing any

and provide the Company and the Shareholder with the opportunity to contest such
disclosure.

                  (d) Integral and the Company acknowledge that they have
entered into a certain Mutual Non-Disclosure Agreement dated May 1, 2000, which
remains in full force and effect in accordance with its terms and shall survive

            5.6   Notice of Developments. The Company and the Shareholder will
                  -----------------------
give prompt written notice to Integral of any material adverse development with

representations and warranties in Section 3 above. Integral

                                       30
<PAGE>

will give prompt written notice to the Shareholder of any breach of any of its
own representations and warranties in Section 4 above. The Company or the
Shareholder shall promptly notify Integral if it or he becomes aware of any
intention of any of the employees to leave the employ of the Company before or
after the Closing Date. No disclosure by any Party pursuant to this Section 5.6,
however, shall be deemed to amend or supplement any Schedule or Exhibit hereto
or to prevent or cure any misrepresentation, breach of warranty, or breach of
covenant.

         5.7   Exclusivity. From the date hereto until August 31, 2000, neither
               -----------
the Shareholder nor the Company or any of its officers, directors, agents,
representatives, or affiliates thereof will (a) solicit, initiate, or encourage
the submission of any proposal or offer from any person relating to the
acquisition of any capital stock or other voting securities, or any substantial
portion of the assets, of the Company (including any acquisition structured as a
merger, consolidation, or share exchange) or (b) participate in any discussions
or negotiations regarding, furnish any information with respect to, assist or
participate in, or facilitate in any other manner any effort or attempt by any
person to do or seek any of the foregoing. The Shareholder will not vote its
Company Common Stock in favor of any such acquisition structured as a merger,
consolidation, or share exchange. The Shareholder will notify Integral
immediately if any person makes any proposal, offer, inquiry, or contact with
respect to any of the foregoing.

         5.8   Pooling Accounting. Integral, the Shareholder and the Company
               ------------------
shall each use its or his reasonable efforts to cause the Merger to be accounted
for as a pooling of interest and shall not take any action that would adversely
affect the ability of Integral to account for the Merger as a pooling of
interest.

         5.9   Tax Returns. Integral shall cause the Company to timely 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, except for such returns required to be filed prior to the Closing Date,
in which case the Company shall timely file such 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 and approval by Integral.
After the Closing Date, Integral and the Company, on the one hand, and the
Shareholder, on the other hand, will make available to the other, as reasonably
requested, 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.

         5.10  Affiliate Agreement. The Shareholder is the only person that is,
               -------------------
in the reasonable judgment of the Company and the Shareholder, an affiliate of
the Company within the meaning of Rule 145 (each such person and "Affiliate")
promulgated under the Securities Act ("Rule 145"). On or before the Closing
Date, the Shareholder shall have executed an affiliate agreement in the form
attached as Exhibit 5.10 (the "Shareholder Affiliate Agreement"). Integral shall
be entitled to place appropriate legends on the Certificate and to issue stop
transfer instructions to the transfer agent for Integral Common Stock consistent

<PAGE>

         6.1   Confidentiality.  Subsequent to Closing, the Shareholder agrees
               ---------------
to continue to abide by the pre-closing confidentiality provisions contained in
Section 5.5 of this Agreement.

         6.2   Operation of the Company Subsequent to the Closing. The
               --------------------------------------------------
Shareholder will not 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 Company after the Closing as it maintained with the
Company prior to the Closing.

         6.3   General. In case at any time after the Closing any further action
               -------
is necessary or desirable to carry out the purposes of this Agreement, each of
the Parties will take such further action (including the execution and delivery
of such further instruments and documents) as any other party reasonably may
request, all at the sole cost and expense of the requesting party (unless the
requesting party is entitled to indemnification therefor under Section 8 below).
The Shareholder acknowledges and agrees that from and after the Closing Integral
will be entitled to possession of all documents, books, records (including Tax
records), agreements, and financial data of any sort relating to the Company.

         6.4   Registration
               ------------

               (a)  Subject to the terms and conditions of this Agreement,
Integral shall file a registration statement with the SEC within 60 days
subsequent to the Effective Time for the purpose of registering the resale of
the shares of Integral Common Stock the Shareholder is to receive pursuant to
Section 1.5 pursuant to the Securities Act and shall use its best efforts to
cause such filed registration statement 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 Closing
Date.

               (b)  In connection with any registration of securities pursuant
to Section 6.4(a) (the "Registrable Securities"), Integral shall

                    (1)  prepare and file with the SEC such amendments and
supplements to such registration statement and the prospectus used in connection
with such registration statement as may be necessary to comply with the
provisions of the Securities Act with respect to the disposition of the
Registrable Securities;

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

                    (3)  use its best 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 Shareholder reasonably request;

                    (4)  use its best efforts to cause all such Registrable
Securities to be listed on each securities exchange or quoted on each inter-
dealer quotation system on which the Integral Common Stock is then listed or
quoted;

                                       32
<PAGE>

               (5)  pay all expenses incurred in connection with such
registration, including but not limited to, 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;

               (6)  indemnify the Shareholder for any liability he suffers by
reason of the filing of such registration statement arising from:

                    (1)  any untrue statement (or alleged untrue statement) of a
material fact contained in such registration statement;

                    (2)  any omission (or alleged omission) to state therein 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 registration statement; provided, however, that the
                                             --------  -------
foregoing indemnity obligation shall not be applicable to the extent that such
liability is caused directly or indirectly by information Shareholder or his
representatives provide or provided to Integral in writing specifically for the
purpose of inclusion in the registration statement.

          (c)  Notwithstanding anything in this Section 6.4 to the contrary, for
a period not to exceed 30 days, Integral may delay the filing or effectiveness
of any registration statement filed in connection with this Section 6.4, or
suspend the use of such registration statement (and the Shareholder hereby
agrees not to offer or sell any shares of Integral Common Stock pursuant to such
registration statement during such period) after receiving notice of such delay
or suspension), at any time when Integral, in its reasonable judgment, believes
that there is or may be in existence material nonpublic information or events
involving Integral, the failure of which to be disclosed in the prospectus
included in such registration statement could result in a violation of the
Securities Act, the Securities Exchange Act of 1934, as amended, or any
provision of any state securities law (the "Suspension Right"). In the event
Integral exercises the Suspension Right, such suspension shall continue for the
period of time, and only such period of time, reasonably necessary for
disclosure to occur at a time that is not detrimental to Integral or its
stockholders or until such time as the information or event is no longer
material, each as determined in good faith by Integral after consultation with
counsel. Integral will promptly give the Shareholder notice of any such delay or
suspension and prompt notice of the cessation of suspension or delay. In the
event Integral reasonably believes that any of the foregoing circumstances are
continuing after such 30-day period, it may, with the consent of the Shareholder
(which consent shall not be unreasonably withheld) extend such 30-day period for
one additional 30-day period. Integral will use all reasonable efforts to
minimize the length of any suspension or delay under this Section 6.4(c);
provided however that nothing contained in this Section 6.4(c) shall be deemed
to require Integral to make any disclosures.

                                       33

     6.5. Changes in Common Stock. If, and as often as, there are any changes in
          -----------------------
the Integral Common Stock 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.

     6.6  Retention Incentive Program Agreement. Promptly after the Effective
          -------------------------------------
Time, Integral shall cause the Company to execute and deliver the Retention

                                       36
<PAGE>

that the scope of loss may not be determined, remedial work completed or claim
otherwise resolved prior to such expiration.

     8.2  Indemnity from Shareholder. Subject to Sections 8.4 and 8.5, the
          --------------------------
Shareholder (the "Indemnifying Party") shall indemnify and hold Integral (the

against any and all losses liabilities (as defined in Section 3.9), 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), reduced to the extent of any recoveries under
any insurance policies and to the extent of any net Tax benefits associated
therewith (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 Indemnifying
Party or the Company contained in this Agreement or in any schedule, exhibit,
certificate, document or other item delivered by the Indemnifying Party, the
Company or their respective representative(s) in connection with this Agreement;

     (ii)  the nonperformance, partial or total, of any covenant or agreement of

or to the enforcement of this Section 8.2. Without limiting the foregoing, the
Shareholder's indemnification liabilities arising from Section 3 of this
Agreement shall include Adverse Consequences consisting of any and all Taxes of
the Company 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 Date and Taxes incurred in the ordinary course of business subsequent
thereto. The Shareholder hereby agrees that he will not make any claim for
indemnification against the Company by reason of the fact that he was a
director, officer, employee, or agent of the Company or was serving at the
request of the Company as a partner, trustee, director, officer, employee, or
agent of another entity (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) prior to the Closing Date with respect to any
action, suit, proceeding, complaint, claim, or demand brought by Integral
against the Shareholder pursuant to Section 8 of this Agreement.

     8.3  Indemnity from Integral. Integral shall indemnify and hold Shareholder
          -----------------------
and the Company harmless to the extent provided in this Section 8 from and
against any and all Adverse Consequences resulting from or arising out of:

          (a)  any breach of any representation or warranty of Integral
contained in this Agreement or in any schedule, exhibit, certificate, document
or other item delivered by Integral or its representative(s) in connection with
this Agreement;

                                       37
<PAGE>

          (b)  the nonperformance, partial or total, of any covenant or
agreement of Integral contained in this Agreement; and

          (c)  any and all Adverse Consequence incidental to any of the
foregoing or to the enforcement of this Section 8.3.

     8.4  Notice of Claim. As used in this Section 8.4, the term "Indemnified
          ---------------
Party" shall mean the party seeking indemnification under Section 8.2 or 8.3, as
the case may be, and the term "Indemnifying Party" shall mean the party
providing indemnification under Section 8.2 or 8.3, as the case may be.

          (a)  If the Indemnified Party makes any claim against the Indemnifying
Party for indemnification, such claim shall be in writing and shall state in
general terms the facts upon which the Indemnified Party makes such claim and
must be received by the Indemnifying Party within the period set forth in the
first sentence of Section 8.1 or else such claim shall be barred and the
Indemnifying Party shall have no indemnification obligations with respect to
such claim.

          (b)  In the event of any claim or demand asserted against the
Indemnified Party by a third party upon which the Indemnified Party may claim
indemnification, the Indemnifying Party shall give written notice to the
Indemnified Party within 30 days after receipt of notice from the Indemnified
Party indicating whether the Indemnifying Party intends to assume the defense of
such claim or demand. If the Indemnifying Party does assume such defense, he
shall indemnify and hold the Indemnified Party harmless from and against any and
all losses, damages and liabilities caused by or arising out of any settlement
or judgment of such claim and may not claim that he does not have an
indemnification obligation with respect thereto. Notwithstanding such
assumption, the Indemnified Party shall have the right to participate in such
defense, by written notice given to the Indemnifying Party within 30 days from
the date of the Indemnifying Party's notice, provided that such participation
shall be at the expense of the Indemnified Party. If the Indemnifying Party
assumes the defense and the Indemnified Party elects not to participate, the
Indemnifying Party shall have the right fully to control and to settle the
proceeding. If the Indemnified Party 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 the Indemnifying Party elects not to assume the defense,
the Indemnified Party shall have the right to do so (at the expense of the
Indemnifying Party), and may settle the same without the consent of the
Indemnifying Party.

          (c)  In the event the Indemnified Party has a claim against the
Indemnifying Party hereunder which does not involve a claim being asserted
against or sought to be collected by a third party, the Indemnifying Party shall
give written notice to the Indemnified Party within 30 days after receipt of
notice from the Indemnified Party indicating whether the Indemnifying Party
disputes such claim. If the Indemnifying Party does not notify the Indemnified
Party within such 30-day period that the Indemnifying Party disputes such claim,
the amount of such claim shall be conclusively deemed a liability of the
Indemnifying Party hereunder. In the event that the Indemnifying Party shall
object in writing to any claim made in accordance with this Section 8.3(c), the
Indemnified Party shall have 30 days to respond in a written statement to the

                                       38
<PAGE>

objection of the Indemnifying Party. If after such 30 day period there remains a
dispute as to any claims, the Parties shall attempt in good faith for 30 days to
agree upon the rights of the respective Parties with respect to each of such
claims. If the Parties should so agree, a memorandum setting forth such
agreement shall be prepared and signed by all Parties. If the Parties cannot
agree within such 30 day period, the Parties shall jointly select a single
arbitrator (the "Indemnification Arbitrator"), the selection of which will not
be unreasonably withheld by either Party, who shall have substantial experience
with respect to the substance of the matters in dispute and shall have the
authority to hold hearings and to render a decision in accordance with the
arbitration rules of the American Arbitration Association. The Indemnification
Arbitrator shall settle any remaining dispute by selecting the position of the
Party that the Indemnification Arbitrator determines, in its sole discretion, to
be the most correct. The determination of the Indemnification Arbitrator shall
be set forth in writing, delivered to each of Integral and the Shareholder and
shall be conclusive and binding on the Parties and shall be non-appealable. The
Party whose position is not chosen by the Indemnification Arbitrator shall pay
all expenses of the Indemnification Arbitrator.

     8.5  Limitation.
          ----------

          (a)  Notwithstanding the above the Shareholder shall not be liable
under this Section 8 to the extent that the Adverse Consequences to Integral
exceeds ten percent (10%) of the product of the Purchase Price multiplied by the
average closing price of Integral Common Stock for the twenty trading day period
preceding the Closing Date.

          (b)  There shall be no liability for indemnification under Section 8
unless and until the aggregate amount of the Adverse Consequences suffered by
the Indemnified Party exceeds Fifty Thousand Dollars ($50,000); provided
however, that any Adverse Consequences suffered by the Indemnified Party
thereafter shall be indemnified hereunder from the first dollar.

          (c)  Integral, the Company and Shareholder hereby agree that with
respect to any breach, violation or non-fulfillment of or default in the
performance of any representation, warranty or covenant of this Agreement for
which a right to claim indemnification is provided in this Section 8, a claim or
an action under and pursuant to the terms, conditions and limitations of this
Section 8 will be the sole and exclusive right and remedy of Integral, the
Company and Shareholder, and that neither Integral, the Company nor Shareholder
will have any other claim, cause of action, right, or remedy for such breach,
violation, non-fulfillment or default, or for any other matter relating to or
arising out of the transactions contemplated by this Agreement, based upon this
Agreement or otherwise; provided, however, that if for any reason a court of
competent jurisdiction or arbitrator refuses to enforce this provision, and
permits Integral, Company or Shareholder to assert any action based other than
upon the right to claim indemnification as provided in this Section 8, Integral,
the Company and Shareholder agree that the amount of such other claim will be
subject to and limited by the provisions of this Section 8. Notwithstanding
anything herein to the contrary, the parties to this Agreement agree that, in
the event of any breach or threatened breach by any party to this Agreement of
any covenant, obligation or other provision set forth in this Agreement for the
benefit of any other party to this Agreement, such other party shall be entitled
(in addition to any other remedy that may be available to it) to (a) a decree or
order of specific performance or mandamus to enforce the observance and
performance

                                       39
<PAGE>

of such covenant, obligation or other provision, and (b) an injunction
restraining such breach or threatened breach. To the extent set forth in the
immediately preceding sentences of this Section 8.5(c), the rights and remedies
of the parties hereto shall be cumulative (and not alternative).

9.   NONCOMPETITION
     --------------

     9.1  Prohibited Activities. The Shareholder acknowledges that, in
          ---------------------
connection with the transactions contemplated by this Agreement, the Shareholder
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 the Shareholder used such information to compete with or assist another
company or entity in competing with Integral. Subject to compliance by Integral
with its obligations under Section 6.4 of this Agreement, the Shareholder agrees
that until the end of the two (2) year period beginning on the Closing Date he
will not, either for himself or as a stockholder, partner, investor, director,
officer, shareholder, consultant, contractor or agent or in any other capacity:

          (1)  Engage in any business, activity or work that is in any way
competitive with the business of Integral within the continental United States
as conducted or, with respect to the Company, as proposed to be conducted, in
each case on the date hereof to the knowledge of the Shareholder.

          (2)  Solicit, directly or indirectly, or cause any other person,
company or entity to solicit, directly or indirectly, any employee or contractor
retained or employed by Integral, or hire or employ, or cause any other person,
company or entity to hire or employ, any employee or contractor whose
immediately preceding employer or contractor was Integral.

          (3)  Disparage Integral to anyone outside of Integral, including
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, satellite
and payload integration and test, satellite and payload data processing, and
satellite and payload simulation, including science, meteorology, and earth
resource applications, and building communication system monitor systems for
satellite owners, operators and users.

     Notwithstanding the above, the foregoing covenant shall not be deemed to
prohibit the Shareholder from acquiring as an investment not more than ten
percent (10%) 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
Section 9, the term "Integral" includes all subsidiaries of Integral (including
without limitation the Company).

     Notwithstanding the foregoing, nothing in this Section 9 shall be construed
to prohibit the Shareholder from engaging in the following business at any
location: Teleport operator and general teleport operations, last mile service
provider, telephone by-pass services to/from overseas and ISP provider.

                                       40
<PAGE>

     9.2  Damages. Because of the difficulty of measuring economic losses to
          -------
Integral as a result of a breach of the foregoing covenant, and because of the
immediate and irreparable damage that could be caused to Integral for which it
would have no other adequate remedy, the Shareholder agrees that the foregoing
covenant may be enforced by Integral in the event of breach by the Shareholder,
by injunctions and restraining orders.

     9.3  Reasonable Restraint. The Parties agree that the foregoing covenants
          --------------------
in this Section 9 impose a reasonable restraint on the Shareholder 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 the Shareholder that such covenants be construed and enforced in
accordance with the changing activities and business of Integral throughout the
term of this covenant. The Parties further agree that in the event the
Shareholder 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(1),
the Shareholder shall not be chargeable with a violation of this Section 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 Section 9 are
          -------------------------
severable and separate, and the unenforceability of any specific covenant shall
not affect 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 Section 9, except
          --------------------
as set forth in Section 9.1, 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 the Shareholder 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
years stated at Section 9.1, during which the agreements and covenants of the
Shareholder made in this Section 9 shall be effective, shall be computed by
excluding from such computation any time during which the Shareholder is found
in a final non-appealable judgement by a court of competent jurisdiction to have
been in violation of any provision of this Section 9. The covenants contained in
Section 9, except as set forth in Section 9.1, 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. The Shareholder hereby agrees that the covenants set
          -----------
forth in this Section 9 are a material and substantial part of the transactions
contemplated by this Agreement.

     9.7  Specific Performance. Because of the difficulty of measuring economic
          --------------------
losses to Integral as a result of a breach of the restrictive covenants set
forth in this Section 9, and because of the immediate and irreparable damage
that would be caused to the Company and/or Integral for which monetary damages
would not be a sufficient remedy, it is hereby agreed that in

                                       41
<PAGE>

addition to all other remedies that may be available to the Company and/or
Integral at law or in equity, the Company and Integral shall be entitled to
specific performance and any injunctive or other equitable relief as a remedy
for any breach or threatened breach of the aforementioned restrictive covenants.

10.  GENERAL
     -------

     10.1  Cooperation. The Shareholder and Integral, for no further
           -----------
consideration, shall each deliver or cause to be delivered to the other on the
Closing Date, and either before of 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. The
Shareholder will cooperate and use his reasonable 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.

     10.2  Successors and Assigns. This Agreement and the rights of the Parties
           ----------------------
hereunder may not be assigned (except by operation of law) and shall be binding
upon and shall inure to the benefit of the Parties hereto, the successors of
Integral, and the heirs and legal representatives of the Shareholder.

     10.3  Entire Agreement. Except for the Confidentiality Agreement described
           ----------------
in Section 10.16, this Agreement (which includes the Schedules hereto) sets
forth the entire understanding of the Parties hereto with respect to the
transactions contemplated hereby. It shall not be amended or modified except by
a written instrument duly executed by each of the Parties hereto. 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. No party hereto has made any representation, warranty or covenant
with respect to the transactions contemplated by this Agreement except as
expressly provided herein.

     10.4  Counterparts. This Agreement may be executed in any number of
           ------------
counterparts and any party hereto 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.

     10.5  Brokers and Agents. Except as set forth in Section 3.24, Integral and
           ------------------
the Shareholder each 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.

                                       42
<PAGE>

     10.6  Expenses. Subject to Section 8, 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 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.

     10.7  Notices. Any notice, request, claim, demand, waiver, consent,
           -------
approval or other communication which is required or permitted hereunder shall
be in writing and shall be deemed given if delivered personally or sent by
telefax (with confirmation of receipt), by registered or certified mail, postage
prepaid, or by recognized courier service, as follows:

pre-arbitration discovery shall be completed within 90 days of the request for

Nothing contained herein shall restrict Integral, the Company or the Shareholder
from seeking equitable remedies in a court of competent jurisdiction for any
alleged violations of the provisions of this Agreement.

     10.9  Severability. If any provision of this Agreement 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 to

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.

<PAGE>

     10.10  Absence of Third-Party Beneficiary Rights. 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, stockholder, member, employee, partner of any party hereto
or any other person or entity.

     10.11  Mutual Drafting. This Agreement is the mutual product of the Parties

            -----------------
any disclosure (whether or not in response to an inquiry) of the subject matter
of this Agreement unless previously approved by Integral in writing. Integral

subject matter of this Agreement by Integral.

     10.15  Termination of Agreement. This Agreement may be terminated at any
            ------------------------
time prior to the Closing Date solely:

            (a) by mutual consent of Integral, the Company and the Shareholder;
or

            (b) by the Company or the Shareholder or by Integral if the
Closing shall not have occurred on or before September 30, 2000; provided,
however, that the right to terminate this Agreement under this Section 10.15(b)
shall not be available to any party whose material misrepresentation, breach of
warranty or failure to fulfill any obligation under this Agreement has been the
cause of, or resulted in, the failure of the Closing to occur on or before such
date; or

            (c) by the Company or the Shareholder or by Integral if there is or
has been a material breach, failure to fulfill or default on the part of the
other party of any of the representations and warranties contained herein or in
the due and timely performance and satisfaction of any of the covenants,
agreements or conditions contained herein, and the curing of such default shall
not have been made or shall not reasonably be expected to occur before the
Closing Date; or

            (d) by the Company or the Shareholder or by Integral if there shall
be a final nonappealable order of a federal or state court in effect preventing
consummation of the Merger;

                                       45
<PAGE>

or there shall be any action taken, or any statute, rule, regulation or order
enacted, promulgated or issued or deemed applicable to the Merger by any
Governmental Authority which would make the consummation of the Merger illegal.

     10.16  Effect of Termination. In the event of the termination of this
            ---------------------
Agreement pursuant to Section 10.15, this Agreement shall forthwith become void,
and there shall be no liability or obligation on the part of any party hereto or
its officers, directors, stockholders or members. Notwithstanding the foregoing
sentence, (i) the provisions of this Section 10.16, Sections 5.5(b) and 5.5(c)
(confidentiality), and the Mutual Non-Disclosure Agreement between Integral and
the Company, dated May 1, 2000, shall remain in full force and effect and
survive any termination of this Agreement; (ii) each party shall remain liable
for any breach of this Agreement prior to its termination; and (iii) in the
event of termination of this Agreement pursuant to Section 10.15(c) above, then
notwithstanding the provisions of Section 10.6 above, the breaching party shall
be liable to the other party to the extent of the expenses incurred by such
other party in connection with this Agreement and the transactions contemplated
hereby, as well as any damages in accordance with applicable law.

     10.17  Definition. As used herein, the phrases "to the knowledge of the
            ----------
Company," "to the best knowledge of the Company," "the Company has no knowledge"
