had occurred. The Sellers, promptly following execution of this Agreement, will
advise the respective contracting officer of the intended subcontract and
facilitate appropriate meetings between the Buyer and the contracting officer.

               (ii) Any modification to a Government Contract approved by the
Sellers prior to the Closing Date will be duly executed by the Sellers.

               (iii) Any other correspondence, invoices, or other written
submissions, including requests for equitable adjustments, claims, contract
modifications, and requests for final decisions will be prepared by the Buyer in
the name of the Sellers, coordinated with and submitted for approval, which
approval shall not unreasonably be withheld or delayed, promptly signed by the
Sellers if approved, and promptly submitted by the Buyer to the Government. The
Sellers shall respond promptly to any request for approval. In this context, the
Sellers hereby designate Edward Gaskell as the "Sellers' Designated Contract
Representative" to receive and execute such documents, and the Buyer hereby
designates John Spears as the "Buyer's Designated Contract Representative" for
all Government Contracts, to submit such documents to, and receive such
documents from, the Sellers' Designated Contract Representative. Either party
may change its Designated Contract Representative by written notice to the
other. In addition, if any certification is required, the Buyer shall certify to
the Sellers in writing that such certification is proper under the Contract
Disputes Act of 1978 (the "CDA"), and not in violation of the False Claims Act,
and upon receipt of such certification the Sellers shall promptly review and
certify the claim under the CDA for submittal to and decision by the contracting
officer.

               (iv) Following the Closing Date, the Sellers will be responsible
for preparing and certifying all pre-Closing Date cost claims, including all of
the Sellers' direct, indirect, and general and administrative cost claims, for
each Government Contract through the Closing Date. The Sellers will promptly
submit such claims to the contracting officer through the Buyer.

               (v) During the Interim Period, each party will cooperate fully at
its own cost and reasonably assist the other to obtain novation of each
Government Contract into the name of the Buyer and under substantially the same
terms and conditions as in effect at the time of Closing and without materially
adverse conditions upon either the Sellers or the Buyer, and to facilitate
performance thereof by the Buyer. Neither party will take any action intended to
interfere with or delay novation.

               (vi) If the appropriate contracting officer refuses to allow the
Buyer to perform a Government Contract pursuant to a subcontract during the
Interim Period, has not acted on the request for novation on a Government
Contract by August 10, 2001, or refuses to permit novation of a Government
Contract under substantially the same terms and conditions as in effect at



                                       15
   16

the time of the Closing in the name of the Buyer and without material adverse
conditions upon either the Sellers or the Buyer and, (A) such decision is no
longer appealable by law or regulation, or (B) the parties jointly agree that
such decision cannot or should not as a practical matter be further pursued,
appealed, or submitted for reconsideration, the parties shall for a period of 30
days consult in good faith on how to proceed. If the parties fail within such
period to agree jointly on the disposition of the affected Government Contract,
either the Buyer or the Sellers may elect to cause all remaining performance
obligations under such contract to be retransferred to the Sellers (a
"Retransfer Event"). Upon such Retransfer Event, the Interim Period will end as
to such contract, and all performance obligations, payments, expenses, cost
reimbursements, fees, and other matters attributable to the period subsequent to
the Interim Period will be for the account of the Sellers. The parties will
thereupon negotiate in good faith and agree upon an equitable adjustment to the
Purchase Price, considering the relative value of the respective Government
Contract and the Buyer's net-of-tax profit to date under the respective
subcontract.

          (d) If a Retransfer Event occurs as to any Government Contract, the
Buyer shall remain responsible for payment of all expenses incurred and other
matters and shall be entitled to retain all cost reimbursements and fees and
other entitlements applicable to the Interim Period for such Government
Contract.

     ARTICLE VIII. INDEMNIFICATION.

     8.1 Compensation and Indemnification by the Sellers. Subject to all of the
provisions of this Article VIII, the Sellers, jointly and severally, by their
execution of this Agreement, hereby agree to indemnify, defend with counsel
reasonably satisfactory to the Buyer, save and hold the Buyer and any of its
respective officers, directors, stockholders, employees, affiliates, and
assignees (collectively, "indemnified persons" and individually, an "indemnified
person") harmless from and against, and to compensate them for, any and all,
demands, claims, actions, causes of action, assessments, damages, liabilities,
losses, expenses, judgments or deficiencies of any nature whatsoever (including,
without limitation, reasonable attorneys' fees and other costs and expenses
incident to any suit, action or proceeding) (collectively, "Losses") received,
incurred or sustained by an indemnified person which shall arise, in whole or in
part, out of or result from: (a) any breach of any representation, warranty or
covenant (including, without limitation, those contained in Article II) or
non-fulfillment of any obligation of the Sellers under this Agreement or under
any exhibit, schedule, certificate or other document furnished in connection
with this Agreement; (b) any claim (including, without limitation, a claim based
on contract, warranty or tort) arising out of the sale of any product or service
of the Division which was sold prior to the Closing Date or any services
rendered by or on behalf of the Division prior to the Closing Date; (c) the
litigation, if any, disclosed on Schedule 2.9 hereto and all related
proceedings; or (d) any federal, state, local or other tax liability, or any
assessment in the nature of any tax, including interest and penalties thereon,
with respect to any fiscal period of the Sellers or portion of a period prior to
the Closing Date, or any tax liability, including interest and penalties
thereon, arising as a result of the Closing.

     8.2 Limitations on Indemnification by the Sellers. Notwithstanding the
foregoing, (a) the right of the Buyer to indemnification under Section 8.1 above
shall be subject to the time limitation set forth in Section 8.5 below, (b) no
indemnification shall be payable pursuant to Section 8.1 (a) above to the Buyer
unless the total of all claims for indemnification pursuant to Section 8.1 (a)
shall exceed $10,000 in the aggregate, whereupon the full amount of such claims
shall be recoverable in accordance with the terms hereof, such amount being a
threshold and not a deductible and (c) the aggregate liability of Sellers
pursuant to this Article VIII shall not exceed $740,000 (less any required
payment(s) not made pursuant to the Non-Competition Agreement referred to in
Section 6.10); provided, however, that these limitations shall not apply to any
indemnification with respect to Losses arising from the fraud, wilful
misrepresentation or deliberate or wilful breach by the Sellers of any of their
representations, warranties or covenants herein or in any agreement, certificate
or instrument delivered pursuant hereto.

     8.3 Compensation and Indemnification by the Buyer. Subject to all of the
provisions of this Article VIII, the Buyer, by its execution of this Agreement,
hereby agrees to indemnify, defend with counsel reasonably satisfactory to the
Sellers, save and hold the Sellers and any of their respective officers,
directors, stockholders, employees, affiliates, and assignees (collectively,
"indemnified persons" and individually, an "indemnified person") harmless from
and against, and to compensate them for, any and all Losses received, incurred
or sustained by an indemnified person which shall arise, in whole or in part,
out of or result from any breach of any representation, warranty or covenant
(including, without limitation, those contained in Article IV) or
non-fulfillment of any obligation of the Buyer under this Agreement or under any
exhibit, schedule, certificate or other document furnished in connection with
this Agreement.

     8.4 Limitations on Indemnification by the Buyer. Notwithstanding the
foregoing, (a) the right of the Sellers to indemnification under Section 8.3
above shall be subject to the time limitation set forth in Section 8.5 below,
(b) no indemnification shall be payable pursuant to Section 8.3 above to the
Sellers unless the total of all claims for indemnification pursuant to Section
8.3 shall exceed $10,000 in the aggregate, whereupon the full amount of such
claims shall be recoverable in accordance with the terms hereof, such amount
being a threshold and not a deductible and (c) the aggregate liability of Buyer
pursuant to this Article VIII shall not exceed $740,000; provided,



                                       18
   19

however, that these limitations shall not apply to any indemnification with
respect to Losses arising from the fraud, wilful misrepresentation or deliberate
or wilful breach by the Buyer of any of its representations, warranties or
covenants herein or in any agreement, certificate or instrument delivered
pursuant hereto.

     8.5 Survival of Representations and Warranties. The representations,
warranties, covenants and obligations of the parties set forth in this Agreement
shall survive any investigation at any time made by or on behalf of the other
parties and shall survive the Closing for three years, notwithstanding the
establishment of a shorter period by any applicable statute of limitations, the
provisions of which are hereby waived, except that liability with respect to any
representation, warranty, covenant or obligation as to which a claim, or notice
of a proposed claim, is made within such three-year period shall continue until
finally determined and paid. Any claim under this Article VIII by an indemnified
person must be made by written notice to the indemnifying party within said
three-year period.

     8.6 Third Party Claims. Should any claims be made or suit or proceeding be
instituted against an indemnified person within the aforesaid three-year period
which, if valid or prosecuted successfully, would be a matter for which such
indemnified person is entitled to be defended, saved harmless or indemnified
under this Article VIII (a "Third Party Claim"), such indemnified party shall
notify the indemnifying party in writing concerning the same promptly after the
assertion or commencement thereof. The indemnified party shall file in a timely
manner any answer or pleading with respect to a suit or proceeding if such
action is necessary to avoid default or other adverse result. The indemnifying
party shall control the defense of any Third Party Claim and shall use its best
efforts to defeat or minimize any loss resulting from such Third Party Claim.
The indemnifying party shall provide the indemnified person with such additional
information and opportunity for consultation as may reasonably be requested by
it. Such indemnified person shall be entitled, at its own expense, to
participate in the defense of a Third Party Claim and to engage counsel for such
purpose. In the event of any dispute regarding the reasonableness of a proposed
settlement, the party which will bear the larger financial loss resulting from
such settlement will make the final determination in respect thereto, which
determination will be final and binding on all involved parties. The indemnified
person shall render all assistance as the indemnifying party shall reasonably
request in the defense of any Third Party Claim.

     8.7 Set-Off. Any amount or amounts due from an indemnifying person to an
indemnified person under this Article VIII may be paid at the indemnifying
person's option by set-off against any amount or amounts owing from the
indemnified person to the indemnifying person pursuant to any instrument,
document or contract, to the extent such amounts are sufficient, without
prejudice to the indemnifying person's right to pursue any other remedies at law
or in equity.
