that such liability arises out of any matter or circumstances that occurred or
existed on or before the Closing Date and (ii) any leak, discharge or release of
Hazardous Materials emanating from any underground storage tanks or their
appurtenant pipes, lines, fixtures and other related

                                     A-I-9

equipment located on the Property (collectively, the "Underground Tanks")
occurring before, on or after the Closing Date unless such leak, discharge or
release results from Buyer or any Affiliate of Buyer or any of their respective
employees, invitees, agents or contractors piercing or cracking an Underground
Tank or pressure testing it without Seller's prior written consent; and

              (g)  any alleged or actual liability and penalties for violations
of or noncompliance with Environmental Laws (as defined in Section
3.18(b)(iii)), to the extent that such liability arises out of any matter that
occurred or existed on or before the Closing Date and, with respect to the
Underground Tanks, on, before or after the Closing Date unless such leak,
discharge or release results from Buyer or any Affiliate of Buyer or any of
their respective employees, invitees, agents or contractors piercing or cracking
an Underground Tank or pressure testing it without Seller's prior written
consent (with the obligations and liabilities referred to in paragraph (f) above
and this paragraph collectively referred to as the "Excluded Environmental
Liabilities").

         2.5  Estimated Balance Sheet and Net Assets.

              (a)  No later than two business days prior to the Closing Date,
Seller shall deliver to Buyer a pro forma balance sheet ("Estimated Balance
Sheet") that shall fairly present as of such date the Acquired Assets and
Assumed Liabilities of the Business being transferred to Buyer hereunder as of
the Closing Date. The Estimated Balance Sheet shall be prepared in accordance
with generally accepted accounting principles ("GAAP") subject to those specific
understandings set forth in Schedule 2.5 hereto, applied on a basis consistent
with Seller's December 31, 1999 audited consolidated balance sheet ("December
Balance Sheet"). In addition, there shall be no changes to the methodologies and
assumptions used to prepare the reserves and contract estimates reflected on the
Estimated Balance Sheet as compared to the methodologies and assumptions used to
prepare the December Balance Sheet.

              (b) At Closing, the net assets of the Business as reflected on the
Estimated Balance Sheet shall be no less than Five Million One Hundred Thousand
Dollars ($5,100,000) ("Net Assets Requirement"). In addition, at Closing, the
amount of working capital of the Business shall be no less than the working
capital as reflected in Seller's balance sheet dated June 31, 1999.

              (c)  If the Estimated Balance Sheet reflects net assets in excess
of the Net Assets Requirement (the amount of such excess referred to herein as
the "Excess Net Assets"), the Excluded Proceeds (whose value shall not exceed
the value of the Excess Net Assets) shall be retained by Seller and shall
constitute Excluded Assets. Buyer shall collect, in the ordinary course of
business, all such Excluded Proceeds and, upon receipt, tender all such proceeds
promptly to Seller.

         2.6  Purchase Price.

              (a)  In consideration of the sale, transfer and assignment by
Seller of the Acquired Assets and the agreements of Seller contained herein and
in the other Transaction Documents, Buyer shall pay and Seller shall receive
from Buyer the Purchase Price set forth in Section 2.6(b) hereof and calculated
in accordance with Section 2.6(c) hereof.

              (b)  The purchase price shall be Eleven Million Dollars
($11,000,000) (the "Purchase Price").

                                     A-I-10
<PAGE>

              (c)  The Purchase Price shall be payable by (i) cash consideration
equal to Seven Million Dollars ($ 7,000,000) ("Cash Consideration") plus (ii)
subject to Section 2.6(d), shares of Common Stock the Market Value (as defined
below) of which is Four Million Dollars ($4,000,000) ("Share Consideration").
The "Market Value" of the Share Consideration shall be calculated by multiplying
the number of shares of Common Stock constituting the Share Consideration times
the Average Market Price. The "Average Market Price" shall mean, with respect to
one share of Common Stock, the average closing price for such share as reported
on the American Stock Exchange, Inc. ("AMEX") for the ten (10) most recent
trading days ending three (3) business days before the Closing Date.

              (d)  Of the Share Consideration, shares of Common Stock the Market
Value of which is One Million Dollars ($1,000,000) ("Escrowed Shares") shall be
held in escrow, pursuant to an agreement substantially in the form attached
hereto as Exhibit 2.6 (the "Escrow Agreement") which Buyer and Seller shall
enter into at the Closing. The Escrow Agreement shall provide, among other
things, that the Escrowed Shares shall be held in escrow for a period of
eighteen (18) months following the Closing and shall be subject to claims by
Buyer for any amounts owed to a Buyer Indemnified Party by Seller pursuant to
Section 10.1 hereof.

         2.7  Purchase Price Adjustment.

              (a)  Within sixty (60) days after the Closing Date, Buyer shall
prepare and deliver to Seller a balance sheet of the Acquired Assets and Assumed
Liabilities of the Business as of the close of business on the Closing Date
("Closing Balance Sheet"). The Closing Balance Sheet shall be prepared in
accordance with GAAP applied on a basis consistent with the December Balance
Sheet. In addition, there shall be no changes to the methodologies and
assumptions used to prepare the reserves and contract estimates reflected on the
Closing Balance Sheet as compared to the methodologies and assumptions used to
prepare the December Balance Sheet. Buyer shall also prepare a proposed
statement of the net assets of the Business to be transferred to Buyer hereunder
using the procedures used in the preparation of the December Balance Sheet
("Buyer's Proposed Calculations").

              (b)  Within thirty (30) days after receipt of the Closing Balance
Sheet, Seller shall notify Buyer of its agreement or disagreement with the
Closing Balance Sheet and the accuracy of any of Buyer's Proposed Calculations;
provided, that Seller may only dispute the Closing Balance Sheet and Buyer's
Proposed Calculations to the extent that they are inaccurate or deviate from the
requirements of paragraph (a) above. During such period, Buyer shall afford
Seller and its representatives reasonable access to any of the Business' books,
records and work papers, personnel, facilities and accountants necessary to
enable Seller and its representatives to review the Closing Balance Sheet and
Buyer's Proposed Calculations. If Seller disputes any aspect of the Closing
Balance Sheet or the amount of any of the Buyer's Proposed Calculations, then
Seller shall have the right to direct its independent accountants, at Seller's
expense, to review and test the Closing Balance Sheet. Seller's representatives
or accountants shall complete their review and test within thirty (30) days
after the date Seller disputes Buyer's Proposed Calculations. If Seller and its
independent accountants, after such review and test, still disagree with Buyer's
Proposed Calculations, and Buyer does not accept Seller's proposed alternative
calculation (the "Seller's Proposed Calculations"), then, within thirty (30)
days after the date Buyer disputes Seller's Proposed Calculations, Seller and
Buyer shall select a third nationally recognized independent accounting firm
(the "Independent Accounting Firm") to resolve the remaining disputed items (the
"Remaining Disputed Items") by conducting its own review and test of the

                                     A-I-11
<PAGE>

Closing Balance Sheet and thereafter selecting either Seller's Proposed
Calculation of the Remaining Disputed Items or Buyer's Proposed Calculation of
the Remaining Disputed Items or an amount in between the two. The Independent
Accounting Firm shall be instructed (i) that the scope of its review shall be
limited solely to the Remaining Disputed Items, (ii) that it shall accept the
Closing Balance Sheet and Buyer's Proposed Calculations except to the extent
that they are inaccurate or deviate from the requirements of paragraph (a)
above, and (iii) that it is to use every reasonable effort to complete such
assignment and deliver copies of such opinion and, if required, revised Closing
Balance Sheet to Buyer and Seller within thirty (30) days following the date
such Remaining Disputed Items are referred to it. Buyer and Seller agree that
they shall be bound by the determination of the Remaining Disputed Items by the
Independent Accounting Firm. The fees and expenses of the Independent Accounting
Firm shall be paid jointly by Buyer and Seller.

              (c)  Upon the determination pursuant to paragraph (b) above as to
the definitive Closing Balance Sheet and the net assets of the Business to be
transferred to Buyer hereunder as of the Closing Date ("Closing Net Assets"),
the Purchase Price shall be either (i) increased by the amount, if any, by which
the Closing Net Assets is greater than the Net Assets Requirement or (ii)
decreased by the amount, if any, by which the amount of the Closing Net Assets
is less than the Net Assets Requirement (the "Adjustment"); provided, however,
in no event will any upward Adjustment exceed Five Hundred Thousand Dollars
($500,000). If the Purchase Price is increased, Buyer shall pay such amount to
Seller, and if the Purchase Price is decreased, Seller shall pay such amount to
Buyer. Any such payment shall be made in cash or same day funds within ten (10)
days after the determination of the Adjustment pursuant to paragraph (b) above.
Any such payment shall bear interest from the Closing Date to the date preceding
payment at a rate equal to the "Prime Rate" as set forth from time to time in
The Wall Street Journal "Money Rates" column from the Closing Date to the date
preceding payment.

         2.8  Closing.

         The sale and purchase of the Acquired Assets hereunder shall occur at a
closing (the "Closing") to be held at the offices of Arnold & Porter, at 399
Park Avenue, New York, New York on June 14, 2000 or at such other place and time
as the parties hereto may agree (the date of the Closing being referred to
herein as the "Closing Date").

         Seller hereby represents and warrants to Buyer as follows:

         3.1  Organization and Qualification.

         Each of Seller and MSSC is a corporation or other legal entity duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation or formation. Seller has all requisite
corporate power and authority and MSSC has all partnership authority to own,
lease and operate its properties and to carry on its business as it is now being
conducted, except for such failures that could not reasonably be expected to
have, individually or in the aggregate, a GAC Material Adverse Effect. Each of
Seller and MSSC is duly qualified to conduct its business, and is in good
standing, in each jurisdiction where the character of its properties owned,
leased or operated, or the nature of its activities, makes such qualification
necessary, except for such failures that could not reasonably be expected to
have, individually or in the aggregate, a GAC Material Adverse Effect. Neither
Seller nor MSSC is in violation of any of the provisions of its Certificate of
Incorporation (or other applicable charter document) or its By-Laws (or other
applicable organizational document).

         3.2  Authority Relative to this Agreement.

         Seller has full corporate power and authority to execute and deliver
this Agreement and to consummate the transactions contemplated hereby. The
execution and delivery of this Agreement and the consummation of the Acquisition
and the other transactions contemplated hereby have been duly and validly
authorized by the Board of Directors of Seller, and no other corporate
proceedings on the part of Seller are necessary to authorize this Agreement or
to consummate the transactions contemplated hereby. This Agreement has been duly
and validly executed and delivered by Seller and, assuming the due
authorization, execution and delivery hereof by Buyer, constitutes a valid and
binding agreement of Seller, enforceable against Seller in accordance with its
terms, except as such validity, binding effect or enforcement may be limited by
bankruptcy, insolvency or similar laws affecting creditors' rights generally or
by equitable principles relating to the availability of remedies.

         3.3  No Violations, etc.

              (a)  Other than the filings, permits, authorizations, consents and
approvals or waivers thereof that are identified in Section 3.3(b) below and
that have been duly made or obtained as contemplated herein, and except as
listed in Schedule 3.3 hereto, neither the execution and delivery of this
Agreement by Seller nor the consummation of the transactions contemplated hereby
nor compliance by Seller with any of the provisions hereof will (i) violate,
conflict with, or result in a breach of any provision of, or constitute a
default (or an event which, with notice or lapse of time or both, would
constitute a default) under, or result in the termination or suspension of, or
accelerate the performance required by, or result in a right of termination or
acceleration under, or result in the creation of any Encumbrance upon any of the
properties or assets of Seller or MSSC under, any of the terms, conditions or
provisions of (x) their respective charters or by-laws (or other applicable
organizational document), (y) any note, bond, mortgage, debenture, indenture or
deed of trust or (z) any license, lease, contract, agreement or other instrument
or obligation to which Seller or MSSC is a party or to which they or any of
their respective properties or assets

<PAGE>

may be subject; or (ii) violate any judgment, ruling, order, writ, injunction,
decree, statute, rule or regulation applicable to Seller or MSSC or any of their
respective properties or assets, except, in the case of clause (i) above, for
any such violations, conflicts, breaches, defaults or other alterations or
occurrences that could not have, individually or in the aggregate, a GAC
Material Adverse Effect and would not, in any material respect, prevent or delay
or otherwise prevent Seller from performing its obligations hereunder.

              (b)  Except as set forth on Schedule 3.3 hereto, no filing or
registration with, no notification to and no permit, authorization, consent or
approval of any Governmental Entity is required of Seller in connection with the
execution and delivery of this Agreement or the consummation of the transactions
contemplated hereby, except such other filings, registrations, notifications,
permits, authorizations, consents or approvals the failure of which to be
obtained, made or given would not, individually or in the aggregate, either have
a GAC Material Adverse Effect or materially impair or delay the ability of
Seller to consummate the transactions contemplated hereby.

              (c)  Seller and MSSC are not in violation of or default under,
except as set forth in Schedule 3.3 hereto, (i) any note, bond, mortgage,
debenture, indenture or deed of trust; or (ii) any license, lease, contract,
agreement or other instrument or obligation to which Seller or any of its
subsidiaries or MSSC is a party or to which they or any of their respective
properties or assets may be subject, except, in the case of clauses (i) and (ii)
above, for such violations or defaults that would not, individually or in the
aggregate, either reasonably be expected to have a GAC Material Adverse Effect
or materially impair the ability of Seller to consummate the transactions
contemplated hereby.

Intellectual Property of Seller or MSSC or any liens or other security interests
in any Intellectual Property of Seller or MSSC; (vi) any sale or other

Receivable reflected in the Estimated Balance Sheet will represent transactions
in the ordinary course of business (including without limitation recoverable
costs and accrued profits on progress completed but not billed under Government
Contracts (as defined in Section 3.19 below) or other contracts) and will be

              (b)  Seller and MSSC, as the case may be, own or have the right to
use all Intellectual Property used in the conduct of the Defense Business and
the business of MSSC. To Seller's Knowledge, none of the Intellectual Property

violates the intellectual property rights of any third parties. Consummation of
the transactions contemplated hereby shall not impair any rights or impose any
obligations with respect to Intellectual Property used in the conduct of the
Defense Business and the businesses of MSSC.

              (c)  There is no pending or, to Seller's Knowledge, threatened (or

business, infringes or violates the intellectual property rights of any third
parties; (ii) asserting that any third parties have any rights to use any of the

Seller or MSSC on a nonexclusive basis; or (iii) which could, if adversely
determined against Seller or MSSC, adversely affect the ability of Seller or
MSSC to use any of the Intellectual Property upon consummation of the
transactions contemplated hereby or thereafter, and to Seller's Knowledge, there
is no basis for any claim of the foregoing types.

              (d)  Neither Seller nor MSSC has given notice to any third parties
asserting infringement by such third parties of any of the Intellectual

against a third party.

pursuant to valid written agreements (the "License Agreements"), enforceable in
accordance with their terms except as such enforceability may be limited by
bankruptcy, insolvency and other laws and regulations affecting creditors'
rights and by general principles of equity.

              (f)  Neither Seller nor MSSC is subject to any bars or other
restrictions with respect to its rights to utilize the Intellectual Property,
except for the terms and conditions of the License Agreements and, to Seller's
Knowledge, no bars or other restrictions on such rights will be created by the
consummation of the transactions contemplated herein.

              (g)  There is no pending or, to Seller's Knowledge, threatened
claim that Seller, MSSC or any licensor is in breach of any of the License
Agreements and, to Seller's Knowledge, no basis for any such claim exists.

applicable contracts of employment, and all such amounts properly accrued
through the Closing Date will be paid on or prior to the Closing Date or will be
properly recorded on Seller's financial statements.

              (f)  Except to the extent that (i) Buyer assumes responsibility

to, an Accepting Employee prior to the Closing under Section 8.3(c) hereof, or

more of the Plans in its entirety (Seller acknowledges that, except to the
extent provided in Section 8.3(c) hereof, Buyer is under no obligation of any
kind whatsoever to adopt or maintain any of such Plans), and then except with
respect to the Plan or Plans so adopted or maintained, neither the consummation
of the transactions contemplated by this Agreement nor the engagement by Buyer
of any present or former employee or present of former director of Seller, MSSC
or any ERISA Affiliate will impose upon Buyer any liability of any nature with
respect to any Plan.

              (g)  With respect to any Plan adopted by Buyer pursuant to Section
3.16(f)(ii) hereof, each of such Plans that is intended to be "qualified" within

Plans has been operated and administered in all material respects in accordance
with its terms and all applicable laws, including but not limited to ERISA and
the Code.

              (h)  To Seller's Knowledge, each person who performs services for
Seller or MSSC has been, and is, properly classified by Seller or MSSC as an
employee or independent contractor.

              (i)  With respect to any Plan adopted by Buyer pursuant to Section
3.16(f)(ii) hereof, there are no material claims pending, or, to Seller's
Knowledge, threatened or anticipated

                                     A-I-22

any such Plan or against Seller or MSSC or any ERISA Affiliate with respect to

court, governmental body, commission, agency or arbitrator outstanding against
or in favor of any such Plan or any fiduciary thereof (other than rules of
general applicability). There are no pending or, to Seller's Knowledge,
threatened audits or investigations by any governmental body, commission or
agency involving any such Plan.

              (j)  Except as set forth in Schedule 3.16(j) hereto, no Plan
provides benefits, including without limitation death or medical benefits
(whether or not insured), with respect to current or former employees or
directors after retirement or other termination of service (other than (i)

ERISA; (iii) deferred compensation benefits accrued as liabilities on the books
of Seller, MSSC or the ERISA Affiliates; or (iv) benefits, the full cost of

consummation of the transactions contemplated by this Agreement will not (i)
entitle any current or former employee or director of Seller or MSSC to

Government Contracts; and (iv) to Seller's Knowledge, all of Seller's Government
Contracts as to which Seller is currently or is likely to experience substantial

true and complete copies of all Government Contracts listed in Schedule 3.19
hereto. Except as described in Schedule 3.19 hereto, all of Seller's Government
Contracts were legally awarded, are binding on Seller and to Seller's Knowledge

Contracts (or, to Seller's Knowledge, the applicable Prime Government Contracts
under which such Government Contracts were awarded) are not currently the
subject of bid protest or analogous proceedings in any agency, administrative or
judicial forum, and to Seller's Knowledge no such Government Contracts (or,
where applicable, the applicable Prime Government Contracts under which such
Government Contracts were awarded) are reasonably likely to become the subject
of bid protest or analogous proceedings.

              (f) Seller has developed and implemented a government contracts
compliance program that includes corporate policies and procedures to ensure

Government nor any prime contractor or higher-tier subcontractor under a

statute, regulation, representation, certification or contract term, condition,
clause, provision or specification.

              (h) To Seller's Knowledge, no facts exist which could give rise to
a claim for price adjustment under any of Seller's Government Contracts under
the TINA or to any other request for a material reduction in the price of any of
Seller's Government Contracts.

              (i) Except as described in Schedule 3.19(i) hereto, Seller has

outstanding disputes or claims against Seller relating to Seller's Government
Contracts and involving either the Government, any prime contractor, any
higher-tier subcontractor or any third party, and to Seller's Knowledge no facts
or allegations exist that could give rise to such a dispute or claim in the
future.

              (k) Except as described in Schedule 3.19(k) hereto, there are no
outstanding disputes or claims against Seller relating to Seller's Government
Contracts which, if resolved unfavorably to Seller, would materially increase
Seller's cost to complete performance of such Government Contract above the
amounts set forth in the Estimates to Complete prepared by Seller and made
available to Buyer for each Government Contract. In addition, except as
described in Schedule 3.19(k) hereto, there are no known or reasonably
foreseeable expenditures which would increase the cost to complete performance
of Seller's Government Contracts above the amounts set forth in the Estimates to
Complete.

              (l) Seller has not been and is not now blacklisted, suspended or
debarred, or proposed for suspension or debarment, from participation in the
award of Government Contracts. No facts exist which could give rise to such
suspension or debarment.

              (m) No negative determination of responsibility has ever been
issued against Seller with respect to any quotation, bid or proposal for a
Government Contract.

              (n) No audit, review, survey, inspection, investigation or

any administrative, civil or criminal investigation or indictment involving
alleged false statements, false claims or other improprieties relating to

Contracts. To Seller's Knowledge there is no basis for any such investigation or
indictment.

exceptions under or to any of the foregoing representations and warranties made

         3.23 Finders or Brokers.

         Neither Seller nor MSSC nor any of their respective Affiliates,

         3.25 Access and Sophistication.

         Seller acknowledges that all documents, books and records requested by
Seller pertaining to Buyer have been made available for inspection by Seller and
its agents and representatives; that Seller and its agents and representatives

Buyer or officers or employees acting on behalf of Buyer concerning the terms
and conditions of the transactions contemplated hereby, including without
limitation the issuance of the shares of Common Stock payable to Seller pursuant
to Section 2.6 hereof, and the business and prospects of Buyer. Seller and its
agents and representatives have such knowledge and experience in financial and
business matters as to enable them to utilize the information made available to
them in connection with the transactions contemplated hereby, to evaluate the
merits and risks of an investment in Buyer and to make an informed decision with
respect thereto and such an evaluation and informed decision have been made.
Seller is an "accredited investor" within the meaning of Regulation D of the
Securities Act of 1933, as amended (the "Securities Act").

         3.26 Investment Representation.

         Seller will acquire the shares of Common Stock payable to Seller
pursuant to Section 2.6 hereof for its own account for investment only and not
with a view to making a distribution thereof within the meaning of the
Securities Act. The parties acknowledge and agree that Seller may distribute the
Common Stock to its shareholders in compliance with the applicable securities
laws and the applicable exemptions from registration thereunder. Seller is aware
that the shares of Common Stock to be distributed to it under the terms of this
Agreement have not been registered under the Securities Act, and, as a result
thereof, are subject to substantial restrictions on transfer and shall bear a
legend in the form specified below restricting the transfer of such shares of
Common Stock. Seller further understands that Buyer has no obligation or

                                     A-I-29
<PAGE>

intention to register the shares of Common Stock to be distributed to Seller
hereunder, under any federal or state securities laws and, therefore, Seller may
be precluded from selling or otherwise transferring or disposing of any of such
shares of Common Stock or any portion thereof and will have to bear the economic
risk of Seller's investment.

                  THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
                  REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
                  UNDER THE SECURITIES LAWS OF ANY STATE AND MAY NOT BE SOLD,
                  TRANSFERRED OR ASSIGNED UNLESS THERE IS AN EFFECTIVE
                  REGISTRATION STATEMENT UNDER SUCH ACT AND ANY APPLICABLE STATE
                  SECURITIES LAWS COVERING SUCH SECURITIES OR THE COMPANY
                  RECEIVES AN OPINION OF COUNSEL (SATISFACTORY TO THE COMPANY
                  AND ITS COUNSEL), OR A "NO-ACTION" OR INTERPRETIVE LETTER FROM
                  THE STAFF OF THE SECURITIES AND EXCHANGE COMMISSION STATING
                  THAT SUCH SALE, TRANSFER OR ASSIGNMENT IS EXEMPT FROM THE
                  REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT
                  AND ANY APPLICABLE STATE SECURITIES LAWS."

                     REPRESENTATIONS AND WARRANTIES OF BUYER

         Buyer hereby represents and warrants to Seller as follows:

         4.1  Organization and Qualification.

         Buyer is a corporation duly organized, validly existing and in good
standing under the laws of the State of Delaware and has all requisite corporate
power and authority to own, lease and operate its properties and to carry on its
business as now being conducted. Buyer is duly qualified as a foreign
corporation to do business, and is in good standing, in each jurisdiction where
the character of its properties owned or leased or the nature of its activities
makes such qualification necessary, except for failures to be so qualified or in
good standing which would not, individually or in the aggregate, have a material
adverse effect on the general affairs, management, business, operations,
condition (financial or otherwise) or prospects of Buyer and its subsidiaries
taken as a whole (an "Buyer Material Adverse Effect"). Except as set forth in
Schedule 4.1 hereto, Buyer is not in violation of any of the provisions of its
Certificate of Incorporation (or other applicable charter document) or By-Laws
(or other applicable organizational document).

         4.2  Authority Relative to this Agreement.

         Buyer has full corporate power and authority to execute and deliver
this Agreement and to consummate the transactions contemplated hereby. The
execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby have been duly and validly authorized by the
Board of Directors of Buyer and no other corporate proceedings on the part of
Buyer are necessary to authorize this Agreement or to consummate the
transactions

                                     A-I-30
<PAGE>

contemplated hereby. This Agreement has been duly and validly executed and
delivered by Buyer and, assuming the due authorization, execution and delivery
hereof by Seller, constitutes a valid and binding agreement of Buyer,
enforceable against Buyer in accordance with its terms, except as such validity,
binding effect or enforcement may be limited by bankruptcy, insolvency or
similar laws affecting creditors' rights generally or by equitable principles
relating to the availability of remedies.

         4.3  Capitalization.

         The authorized capital stock of Buyer consists of 20,000,000 shares of
Common Stock, and 20,000,000 shares of undesignated preferred stock, no par
value per share. As of February 10, 2000, 9,716,833 shares of Common Stock are
issued and outstanding and no shares of preferred stock are issued and
outstanding. All of such issued and outstanding shares are validly issued, fully
paid and non-assessable and free of preemptive rights. As of February 10, 2000,
Buyer holds 440,939 shares of Common Stock in treasury. Except as set forth
above and except as disclosed in Schedule 4.3 hereto, there are not as of the
date hereof any shares of capital stock of Buyer issued or outstanding or any
subscriptions, options, warrants, calls, claims, rights (including without
limitation any stock appreciation or similar rights), convertible securities or
other agreements or commitments of any character obligating Buyer to issue,
transfer or sell any of its securities. Except as disclosed in Schedule 4.3
hereto, Buyer is not a party to any voting agreement, voting trust, proxy or
similar agreement, arrangement or understanding relating to its capital stock or
any agreement, arrangement or understanding relating to or providing for
registration rights with respect to its capital stock.

         4.4  Subsidiaries.

         The only direct or indirect subsidiaries of Buyer as of the date hereof
are those listed in Schedule 4.4 hereto. As of the date hereof, Buyer is
directly or indirectly the record (except for directors' qualifying shares) and
beneficial owner (including all qualifying shares owned by directors of such
subsidiaries as reflected in Schedule 4.4 hereto) of all of the outstanding
shares of capital stock of its subsidiaries, there are no proxies with respect
to such shares, and no equity securities of any of such subsidiaries are or may
be required to be issued by reason of any options, warrants, scrip, rights to
subscribe for, calls or commitments of any character whatsoever relating to, or
securities or rights convertible into or exchangeable for, shares of any capital
stock of any such subsidiaries, and there are no contracts, commitments,
understandings or arrangements by which any such subsidiary is bound to issue
additional shares of its capital stock or securities convertible into or
exchangeable for such shares.

         4.5  Valid Issuance of Securities.

         The shares of Common Stock being issued to the Seller pursuant to
Section 2.6 hereof, when issued, sold and delivered in accordance with the terms
hereof for the consideration expressed herein, will be duly and validly issued,
fully paid and nonassessable. Subject to the accuracy of the representations of
Seller in this Agreement such shares of Common Stock will be issued in
compliance with all applicable federal and state securities laws.

that have been duly made or

                                     A-I-31
<PAGE>

obtained as contemplated herein, neither the execution and delivery of this
Agreement by Buyer nor the consummation transactions contemplated hereby nor
compliance by Buyer with any of the provisions hereof will (i) violate, conflict
with, or result in a breach of any provision of, or constitute a default (or an
event which, with notice or lapse of time or both, would constitute a default)
under, or result in the termination or suspension of, or accelerate the
performance required by, or result in a right of termination or acceleration
under, or result in the creation of any Encumbrance upon any of the properties
or assets of Buyer under, any of the terms, conditions or provisions of (x) its
charter or by-laws or the applicable rules of the AMEX, the stock exchange on
which the Common Stock is publicly traded, (y) any note, bond, mortgage,

the statutes and regulations referred to in the next paragraph, violate any
judgment, ruling, order, writ, injunction, decree, statute, rule or regulation
applicable to Buyer or any of its properties or assets, except, in the case of
clauses (i) and (ii) above, for such violations, conflicts, breaches, defaults,
terminations, suspensions, accelerations, rights of termination or acceleration
or creations of Encumbrances which would not, individually or in the aggregate,
either have an Buyer Material Adverse Effect or materially impair Buyer's
ability to consummate the transactions contemplated hereby.

              (b)  No filing or registration with, no notification to and no
permit, authorization, consent or approval of any Governmental Entity is
required of Buyer in connection with the execution and delivery of this
Agreement or the consummation of the transactions contemplated hereby, except
such filings, registrations, notifications, permits, authorizations, consents or
approvals the failure of which to be obtained, made or given would not,
individually or in the aggregate, either have an Buyer Material Adverse Effect
or materially impair Buyer's ability to consummate the transactions contemplated
hereby.

              (c)  Buyer is not in violation of or default under, except as set
forth in Schedule 4.6(c) hereto, (i) any note, bond, mortgage, indenture or deed
of trust; or (ii) any license, lease, contract, agreement or other instrument or
obligation to which Buyer is a party or to which it or any of its properties or
assets may be subject, except, in the case of clauses (i) and (ii) above, for
such violations or defaults which would not, individually or in the aggregate,
either have an Buyer Material Adverse Effect or materially impair Buyer's
ability to consummate the transactions contemplated hereby.

         4.7  Litigation.

         Except as set forth in Schedule 4.7 hereto, there is no (i) claim,
action, suit or proceeding pending or, to the best knowledge of Buyer,
threatened against or relating to Buyer before any court or governmental or
regulatory authority or body or arbitration tribunal; or (ii) outstanding
judgment, order, writ, injunction or decree, or application, request or motion
therefor, of any court, governmental agency or arbitration tribunal in a
proceeding to which Buyer is a party, except, in the case of clauses (i) and
(ii) above, such as would not, individually or in the aggregate, materially
impair Buyer's ability to consummate the transactions contemplated hereby.

advisable to consummate and make effective as promptly as practicable the

of Seller's obligations contemplated in this Article VI.

         6.2  Third Party Consents.

              (a)  To the extent that any agreement or contract constituting
part of the Acquired Assets is not capable of being transferred by Seller to
Buyer pursuant to this Agreement without the consent, approval or waiver of a
third Person, and such consent is not obtained prior to the Closing, or if such
transfer or attempted transfer would constitute a breach thereof or a violation
of any law, rule or regulation in the absence of obtaining such an approval,
nothing in this Agreement will constitute a transfer or an attempted transfer
thereof. Each of Buyer and Seller shall use commercially reasonable efforts at
Buyer's expense to obtain any such approvals.

              (b)  In the event that such consents, approvals and waivers
referred to in paragraph (a) are not obtained, then Seller and Buyer will each
use commercially reasonable efforts, at Buyer's expense and in compliance with
applicable laws and regulations, to (i) provide to Buyer the benefits and
burdens of any such agreement, (ii) cooperate in any reasonable and lawful

of Buyer as the agent of Seller for purposes of such agreement, and (iii)
enforce, at the request of Buyer for the account of Buyer, any rights of Seller

Contracting Officer (as such term is defined in FAR Part 42, (P) 42.1202(a)),
which shall be submitted by Seller to each Responsible Contracting Officer, for
the United States Government (i) to recognize Buyer as Seller's successor in
interest to all the Acquired Assets constituting a United States Government

in form and substance reasonably satisfactory to Buyer and Seller and their
respective counsel, pursuant to which, subject to the requirements of the FAR
Part 42, all of Seller's right, title and interest in and to, and all of
Seller's obligations and liabilities under, each such United States Government
Contract shall be validly conveyed, transferred and assigned and novated to
Buyer by all parties thereto. Seller shall provide to Buyer promptly any
information regarding Seller required in connection with such request. Seller

the most expeditious manner possible all licenses, consents, approvals and
waivers required for the purpose of processing, entering into and

paragraph (a) hereof, Seller shall not consent to any modification of any
Government Contract included in the Acquired Assets without the prior written
consent of Buyer, not to be unreasonably withheld or delayed.

Buyer.

         6.5  Schedules.

not limited to Tax records), contracts and documents of the Defense Business and
business of MSSC as Buyer shall reasonably request in connection with its review
of the Defense Business and business of MSSC, and Seller shall furnish or cause
to be furnished to Buyer and its authorized representatives all such information
with respect to the Defense Business and business of MSSC as Buyer may
reasonably request. Any such investigation shall be on reasonable prior notice
and shall be carried out in such a manner as to minimize any disruption of the
operations of the Defense Business and the business of MSSC.

be, or of any officer, director, employee or agent thereof, to comply with or
satisfy any covenant, condition or agreement to be complied with or satisfied by
it under this Agreement; provided, however, that no such notification shall
affect the representations or warranties of the parties or the conditions to the
obligations of the parties hereunder.

              (b)  Seller shall advise Buyer in writing, promptly after becoming

the Closing Date (i) with respect to any Taxable Year that ends on or before the
Closing Date or (ii) to the extent that any such Taxes are allocable to that
portion of any Split Period that ends on the Closing Date. For purposes of this

that ends on the Closing Date shall be determined on the basis of a deemed
closing on the Closing Date of the books and records of Seller and its
Affiliates. Seller shall also remain responsible for the filing of all related
Tax Returns relating to the Business and which are due before the Closing Date.

Purchase Price shall be allocated among the Acquired Assets and Assumed
Liabilities (the "Allocation Schedule") as set forth on Schedule 6.11(b)
attached hereto, subject to such changes in the Acquired Assets and Assumed
Liabilities as occur prior to the Closing Date. The Parties agree to file all
Tax Returns and other statements for Tax purposes consistently with the

of Internal Revenue Service Form 8594), Treasury Regulation Section 1.743-1(k),
Treasury Regulation Section 1.755-1 and /or Treasury Regulation Section 1.755-2T

with those provisions. None of Buyer, Seller or any Affiliate of Buyer or Seller
shall take a position in any Tax proceeding, Tax audit, or otherwise that is
inconsistent with the allocation set forth on the Allocation Schedule; provided,
however, that (i) nothing contained herein shall require Buyer or Seller to
contest any challenge to such allocation, and (ii) nothing contained herein
shall prevent Buyer, Seller or any of their Affiliates from filing protective
amended Tax Returns or claims for refunds after a Tax authority has challenged
such allocation. Each of Buyer and Seller shall notify the other if it receives
notice that any Tax authority proposes any allocation different from the
Allocation Schedule.

              (c)  Transfer Taxes. Notwithstanding any other provisions of this
Agreement, Buyer and Seller shall each be responsible for one-half of all
applicable transfer, documentary, sales, use, stamp, registration, and other
such similar Taxes and related costs ("Transfer Taxes") incurred in connection
with the transactions contemplated by this Agreement. Each of the Parties hereby
agrees to pay all such Taxes and other related costs and to file all necessary
documentation as required under the applicable statutory provisions with respect
to all such Taxes in a timely manner. Following any such payment and filing by
any party hereto, or any of its Affiliates, such party shall be entitled to be
reimbursed by the other party for one-half of the amount paid. The Parties shall
take all reasonable actions to minimize the amount of such Transfer Taxes.

9.2(d) or 9.3(d), Seller and Buyer will meet the appropriate government

Buyer in connection with such transition process. During a reasonable transition
period but in

Seller will export products of Buyer under Seller's export licenses.

              (b) Buyer agrees to reimburse Seller for any out-of-pocket costs
incurred in connection with the arrangements described in (a) above.

lease, substantially in the form attached hereto as Exhibit 6.13 (the "Lease"),

additional consecutive two-month periods on terms and conditions to be agreed
upon by Buyer and Seller or GARC, as the case may be, at such time.

         6.14 Environmental Matters

that Seller purchase an environmental insurance policy for the benefit of Buyer
in the form of the policy endorsements previously agreed to by Buyer and Seller
(the "Insurance Policy"). Seller agrees to use its best efforts to obtain such
Insurance Policy; provided that the total premium required to be paid by Seller
shall not exceed $37,500.

effect to all renewals thereof), Seller agrees to take all steps required under
the rules and regulations of the Pennsylvania Department of Environmental
Protection ("PADEP") to obtain Act II Clearance with respect to the Property.

representatives reasonable access to all books, records and other data included
in the Defense Business and the business of MSSC during regular business hours
upon reasonable prior notice if such access is reasonably required by Seller in
connection with its legal, Tax, regulatory or contractual matters (including as
may be necessary to enable Seller to prepare Tax Returns or reports for or on
behalf of Seller or MSSC or to prepare for or to respond to any Tax audit).

         7.4  Further Assurances

prior service of any Accepting Employee with Seller as if it had been service
with Buyer for purposes of (i) eligibility for participation and vesting (but
not benefit accrual) under its 401(k) plan, (ii) eligibility to participate in
Buyer's medical, dental and other welfare plans, but not for purposes of
determining eligibility for any post-retirement medical, dental and other
similar benefits, (iii) accruing annual vacation under the appropriate schedule
applicable to Accepting Employees from time to time, and (iv) determining the
amount of severance due to any Accepting Employee on the termination of their
employment under Buyer's then existing severance program.

              (b)  Except to the extent provided in Section 8.3(c) hereof,
Seller and Seller Plans shall retain all liability, responsibility and
obligation for all employment and benefit related liabilities or obligations of
whatever nature, including without limitation under any Seller Plan, with
respect to all Accepting Employees arising from or relating to their employment
with Seller with respect to claims incurred or based on events, acts, omissions,
conduct or course of conduct,

                                     A-I-42
<PAGE>

to the extent that such claims were incurred or such events, acts, omissions,
conduct or course of conduct occurred on or before the Closing Date (except that
in the case of Inactive Employees, the Inactive Employee Hire Date shall be
substituted for the Closing Date.) Buyer and Buyer's benefit plans shall have
all liability, responsibility and obligation for all employment related
liabilities or obligations with respect to any Accepting Employee, with respect
to claims incurred or based on events, acts, omissions, conduct or course of
conduct, to the extent that such claims were incurred or such events, acts,
omissions, conduct or course of conduct occurred after the Closing Date (except
that in the case of Inactive Employees, the Inactive Employee Hire Date shall be
substituted for the Closing Date), and relates to their employment with Buyer.
Notwithstanding the foregoing, Seller and the Seller Plans have all liability,
responsibility and obligation for any eligible health care or other eligible
welfare expenses and services incurred through the Closing Date (except that in
the case of an Inactive Employee, the Inactive Employee Hire Date shall be
substituted for the Closing Date). For purposes of the foregoing sentence, an
expense or service is deemed incurred when the medical or dental services are
performed (except in the case of hospital services and expenses, which are
deemed to be incurred on the date the covered person first enters the hospital),
or, with respect to welfare benefits other than medical and dental benefits,
when the latest event giving rise to such expense or benefit occurs.

              (c)  Buyer shall be responsible for accrued vacation benefit days
not taken by or otherwise not paid by Seller to an Accepting Employee prior to
the Closing, but only to the extent accrued for on the Closing Balance Sheet.

              (d)  Buyer agrees that any pre-existing condition exclusion in any
of Buyer's health insurance plans and policies shall not be applicable to each
Accepting Employee effective as of the effective date of such Accepting
Employee's employment with Buyer, except to the extent such exclusions actually
applied to limit, restrict or deny coverage to an Accepting Employee under the
corresponding Seller Plans that provided medical benefits to the Accepting
Employee on the day prior to the effective date of such Accepting Employee's
employment with Buyer. Buyer shall cause its health and other welfare benefit
plans and policies that provide medical and dental benefits to credit the
Accepting Employees with any deductible or maximum out-of-pocket payments made
by such Accepting Employees under Seller's health and other welfare benefit
plans and policies that provide medical and dental benefits so as to reduce the
amount of any deductible or maximum out-of-pocket payments payable by the
Accepting Employees under Buyer's health and other welfare benefit plans and
policies that provide medical and dental benefits; provided that the Accepting
Employees provide to such Buyer benefit plans and policies such information as
Buyer may specify to implement such credits. Seller shall make available to each
Accepting Employee within twenty (20) days after the Closing such information as
is reasonably necessary to permit the Accepting Employee to apply for such
credits.

              (e)  Effective as of the Closing Date, all Accepting Employees
shall be fully vested in their accrued benefit under any Seller Plan that is an
"employee pension plan" as that term is defined in Section 3(2) of ERISA.

              (f)  Prior to the Closing Date, Seller shall pay all bonus and
incentive compensation amounts payable or accrued with respect to any Accepting
Employee under any Seller Plan or otherwise (including any bonus or incentive
compensation of any kind whatsoever) with respect to any period that includes,
or ended on or prior to, the Closing Date (except that in the case of an
Inactive Employee, the Inactive Employee Hire Date shall be substituted for the
Closing Date in this Section 8.3(f)).

                                     A-I-43
<PAGE>

              (g)  All wages, employee withholding taxes, commissions, employee
payroll deductions, employer matching and any profit sharing or other
contribution to any Seller Plan relating to the employment of any Accepting
Employee through the Closing Date shall be paid by Seller prior to the Closing
Date (except that in the case of an Inactive Employee, the Inactive Employee
Hire Date shall be substituted for the Closing Date in this Section 8.3(g)).

         8.4  Retention of Employees.

         Seller shall use commercially reasonable efforts (but shall not be
required to expend money, except as set forth herein) to retain the Designated
Employees during the period between the execution of this Agreement and through
and including the Closing Date and to encourage all such Designated Employees to
accept offers of employment from Buyer, including, but not limited to, the
following:

              (a)  maintaining all current compensation programs or benefits
programs that are intended to assist in retaining employees; and

              (b)  assisting Buyer in communicating with the Designated
Employees regarding offers of employment by Buyer.

Nothing contained in this Section 8.4 shall prohibit Seller from terminating or
disciplining any individual who Seller believes, in its sole discretion, should
be terminated or disciplined in a manner consistent with past practices,
policies and procedures.

         8.5  Cooperation

         Seller and Buyer agree to cooperate and take such further actions as
may be reasonably necessary to carry out the intent of this Article VIII,
including but not limited to (i) the conduct of meetings by Buyer, if it so
elects, with Employees during breaks outside of scheduled work or at such times
reasonably agreed to by Buyer and Seller prior to the Closing Date for purposes
including but not limited to employment interviews, enrollment of Accepting
Employees in Buyer's benefit plans and employee orientation for Accepting
Employees, and (ii) the exchange of such information as may be necessary to
administer Buyer's benefit plans and the Seller Plans. Seller agrees to permit,
at such times and places reasonably agreed to by Buyer and Seller and to the
extent permitted by applicable laws and subject to appropriate safeguards, Buyer
to review the Seller's personnel files and other employee-related records and
data.

                                 INDEMNIFICATION

         10.1  Indemnification by Seller.

         From and after the Closing, Seller hereby agrees to indemnify, defend
and hold Buyer and its officers, directors, agents and employees (the "Buyer
Indemnified Parties"), harmless from, against and in respect of any and all
losses, claims, suits, actions, proceedings, awards, judgments, settlements,
fines, penalties, liabilities, obligations, damages, deficiencies, costs or
expenses (including, without limitation, reasonable expenses of investigation
and attorneys' fees) net of any insurance proceeds and tax benefits if, as and
when received, in either case to which such Buyer Indemnified Party is entitled
by virtue of any of the foregoing (collectively "Claims") arising out of or
resulting from:

              (a)  any breach of any warranty or misrepresentation by Seller or
the breach or nonperformance of any covenant, agreement or obligation to be
performed on the part of Seller under this Agreement, or in any closing
certificate contemplated hereby or in any Schedule hereto;

              (b)  the conduct of the Business prior to the Closing, except for
liabilities specifically assumed by Buyer herein and reserved for on the Closing
Balance Sheet;

              (c)  any liability for Taxes incurred with respect to any Taxable
Year ending on or before the Closing Date and that portion of any Split Period
ending on the Closing Date;

              (d)  the MSSC Interest or the Joint Venture Agreement on or prior
to the Closing;

              (e)  the Excluded Assets; and

              (f)  the Excluded Liabilities.

         10.2 Indemnification by Buyer.

              From and after the Closing, Buyer hereby agrees to indemnify,
defend and hold harmless Seller and its officers, directors, agents and
employees (the "Seller Indemnified Parties") from, against and in respect of any
and all Claims arising out of or resulting from (i) any breach of any warranty
or misrepresentation by Buyer or the breach or nonperformance of any covenant,
agreement or obligation to be performed on the part of Buyer under this
Agreement, or in any closing certificate contemplated hereby or in any Schedule
hereto; (ii) any Assumed Liabilities and (iii) except for the Excluded
Liabilities and the Excluded Assets, the MSSC Interest, operation of the Defense
Business and the use of the Acquired Assets in the operation thereof after the
Closing Date.

         10.3 Limitations.

              (a)  Notwithstanding anything contained in this Agreement to the
contrary: (i) neither party shall be liable for any amounts for which an
Indemnified Party (as defined below) is otherwise entitled to indemnification in
connection with the breach or inaccuracy of any representation or warranty or
any breach of any covenant contained herein until the aggregate amount for which
such Indemnified Party is entitled to indemnification with respect to all such

                                     A-I-47
<PAGE>

Claims for indemnification in the aggregate exceed Fifty Thousand Dollars
($50,000) (the "Threshold"), at which time such party shall be liable for any
such excess, and (ii) nor shall a party indemnifying another party hereto be
required to make indemnification in connection with the breach or inaccuracy of
any representation or warranty or any breach of any covenant contained herein to
the extent indemnification payments with respect to all such claims for
indemnification would exceed in the aggregate Eleven Million Dollars
($11,000,000) (the "Maximum Indemnification Amount"). In determining the
foregoing Threshold and in otherwise determining the amount to which the
Indemnified Party is entitled to assert a claim for indemnification pursuant to
this Article 10, only actual losses shall be considered. The Threshold and
Maximum Indemnification Amount shall not apply as to any Claims related to: (i)
the Excluded Assets; (ii) the Excluded Liabilities; and (iii) a final,
non-appealable judgment of a court of competent jurisdiction that either party
has committed fraud against the other with respect to the transactions
contemplated under this Agreement. The parties hereto waive as against each
other any claim to consequential, special, exemplary or punitive damages except
to the extent consequential, special, exemplary or punitive damages are awarded
to a third Person against an Indemnified Party in circumstances in which such
Indemnified Party is entitled to indemnification hereunder such consequential,
special, exemplary or punitive damages so awarded shall be payable to such
Indemnified Party hereunder.

              (b)  Indemnification Claims brought under Section 10.1 other than
those arising from the Excluded Assets or the Excluded Liabilities, shall be
satisfied exclusively by Seller first from the Escrowed Shares pursuant to the
Escrow Agreement and then, to the extent such Claims exceed the value of the
Escrowed Shares, or are made after the termination of the escrow established
pursuant to the Escrow Agreement, such excess shall be satisfied by the
remaining Cash Consideration and then the Share Consideration.

              (c)  The respective obligations of the parties to indemnify in
connection with the breach or inaccuracy of any representation or warranty or
any breach of a covenant contained herein shall expire: (i) eighteen (18) months
after the Closing Date as to Claims solely between the parties hereto which are
not brought within such time period, (ii) six (6) months following the
expiration of all appropriate statutes of limitations as to Claims involving the
representation and warranty referred to in Section 3.15 (Taxes) hereof and
Claims brought by third Persons (including Employees), and (iii) seven (7) years
after the Closing Date as to Claims involving the representation and warranty
referred to in Section 3.18 (Environmental Matters) hereof. Claims relating to
the representations and warranties referred to in Section 3.8 (Title to Assets)
hereof and Section 4.5 (Valid Issuance of Securities) hereof shall not expire.
Notwithstanding the foregoing, the respective indemnification obligations of the
parties hereunder shall not expire with respect to any Claim brought within such
specified time periods until the indemnification obligation, if any, with
respect to such Claim shall have been finally determined and paid.

         10.4 Indemnification Procedure.

         In any case under this Agreement where Seller has indemnified a Buyer
Indemnified Party or Buyer has indemnified a Seller Indemnified Party (the
indemnifying party hereinafter the "Indemnifying Party" and the party entitled
to indemnification hereinafter the "Indemnified Party") against any Claim,
indemnification shall be conditioned on compliance with the procedure and shall
be subject to the limitations outlined below:

                                     A-I-48
<PAGE>

              (a)  Provided that prompt notice is given of a Claim for which
indemnification might be claimed under this Article 10, unless the failure to
provide such notice does not actually and materially prejudice the interests of
the Indemnifying Party, the Indemnifying Party promptly will defend, contest, or
otherwise protect against any such Claim at its own cost and expense. Such
notice shall describe the Claim in reasonable detail and shall indicate the
amount (estimated, if necessary) of the loss that has been or may be suffered by
an Indemnified Party.

              (b)  An Indemnified Party may, but will not be obligated to,
participate at its own expense in a defense thereof by counsel of its own
choosing, but the Indemnifying Party shall be entitled to control the defense
unless such Indemnified Party has relieved the Indemnifying Party from liability
with respect to the particular matter, provided that the Indemnifying Party may
only settle or compromise the matter subject to indemnification without the
consent of the Indemnified Party if such settlement includes a complete release
of all Indemnified Parties as to the matters in dispute and provided further
that such Indemnified Party will not unreasonably withhold consent to any
settlement or compromise that requires its consent.

              (c)  In the event the Indemnifying Party fails to timely defend,
contest, or otherwise protect against any such Claim, an Indemnified Party may,
but will not be obligated to, defend, contest, or otherwise protect against the
same, and make any reasonable compromise or settlement thereof and recover the
entire costs thereof from the Indemnifying Party, including reasonable
attorneys' fees, disbursements and all amounts paid as a result of such Claim or
the compromise or settlement thereof; provided, however, that if the
Indemnifying Party undertakes the defense of such matter, an Indemnified Party
shall not be entitled to recover from the Indemnifying Party for its costs
incurred in the defense thereof other than the reasonable costs of providing
assistance.

              (d)  The Indemnified Parties shall cooperate and provide such
assistance as the Indemnifying Party may reasonably request in connection with
the defense of the matter subject to indemnification and in connection with
recovering from any third parties amounts that the Indemnifying Party may pay or
be required to pay by way of indemnification hereunder. The Indemnified Parties
shall take commercially reasonable steps to protect its position with respect to
any matter that may be the subject of indemnification hereunder in the same
manner as it would any similar matter where no indemnification is available.

         10.5 Magnavox Asset Purchase Agreement and Subrogation

              (a)  In the event that Buyer recovers losses from Seller pursuant
to this Article 10 and such losses come within the scope of, and are recoverable
by Buyer from Magnavox or General Atronics Corporation under, the
indemnification provisions contained in Section 10 of the Magnavox Asset
Purchase Agreement ("Magnavox Indemnity"), Seller shall be subrogated to the
indemnification rights of Buyer under the Magnavox Asset Purchase Agreement, as
transferred and assigned to Buyer hereunder, and may enforce and exercise such
rights against, and seek recovery from, Magnavox or General Atronics
Corporation, as the case may be, to the extent provided under Section 10 of the
Magnavox Asset Purchase Agreement.

              (b)  In the event that Seller (and not Buyer) becomes subject to
any Claim and such Claim comes within the scope of the Magnavox Indemnity, Buyer
agrees to assign to Seller its rights under the Magnavox Indemnity so that
Seller may seek redress directly from Magnavox under the terms of the Magnavox
Indemnity.

                         final and non-appealable; or

                   (iii) if the value of the Acquired Assets prior to Closing is
                         less than Four Million Five Hundred Thousand Dollars
                         ($4,500,000).

              (c)  by Seller, if Buyer shall have breached or failed to perform
in any material respect any of its representations, warranties, covenants or
other agreements contained in this Agreement; or

              (d)  by Buyer, if Seller shall have breached or failed to perform

other agreements contained in this Agreement.

or directors or officers in respect thereof except for agreements which survive

might have arising from a breach of this Agreement.

         12.4 Counterparts.

         This Agreement may be executed in two or more counterparts, each of
which shall be deemed an original, but all of which together shall constitute
one and the same instrument.

         12.5 Interpretation.

         The headings of articles and sections herein are for convenience of
reference, do not constitute a part of this Agreement, and shall not be deemed
to limit or affect any of the provisions hereof.

         12.6 Amendment.

         This Agreement may not be amended except by an instrument in writing
signed on behalf of each of the parties.

         12.7 No Third Party Beneficiaries.

         Nothing in this Agreement shall confer any rights upon any person or

         12.8 Successors and Assigns.

         The Agreement shall be binding upon and shall inure to the benefit of
the parties, their respective successors and assigns and their respective
shareholders to whom the assets of such party are distributed in the event of
dissolution, but only as to each shareholder to the extent of the assets
distributed to such shareholder; provided, however, that neither this Agreement
nor any rights hereunder may be assigned by any party without the consent of the
other party hereto; provided further, however, that Buyer shall, without
Seller's consent, have the right to designate prior to the Closing Date, any
other direct or indirect wholly-owned subsidiary of Seller that will, in lieu of

designation shall not affect the obligations of Buyer hereunder.

         12.11  Validity.

         The invalidity or unenforceability of any provision of this Agreement
shall not affect the validity or enforceability of any other provisions of this
Agreement, which shall remain in full force and effect.

         12.12  Arbitration

              (a)  The parties shall use their best efforts to resolve any
Dispute (as defined in paragraph (b) below) through negotiation. If, and only
if, the parties fail to resolve the Dispute through such negotiations, either
party may initiate an arbitration proceeding in accordance with this Section
12.12.

              (b) Subject to paragraph (a) above, any dispute, controversy,
claim or difference between the parties with respect to any matter related to or
arising out of this Agreement (each, a "Dispute"), including any question
regarding the existence, validity or termination hereof, shall be referred to
and finally resolved by arbitration administered by the American Arbitration
Association in accordance with the Commercial Arbitration Rules of the American
Arbitration Association and the provisions of this Section 12.12. Any
arbitration proceeding (each, a "Proceeding") shall be held in New York, New
York.

              (c) Each party shall appoint one arbitrator within thirty (30)
calendar days after the Proceeding has been initiated. If either party fails to
appoint an arbitrator within such time, such arbitrator shall be appointed by
the American Arbitration Association. The arbitrators so appointed shall appoint
a third arbitrator within thirty (30) calendar days after the appointment of the
second arbitrator. If they fail to do so within such time, the third arbitrator
shall be appointed by the American Arbitration Association within the next
twenty (20) calendar days. The third arbitrator shall act as chairman of the
arbitration. If any arbitrator is required to be replaced, the replacement
arbitrator shall be appointed.

              (d) The arbitrators shall decide all Disputes by a majority vote
in accordance with this Agreement and the laws of the State of Delaware
applicable to contracts made and to be performed entirely within such State. The
decision of the arbitrators shall be in writing and presented in separate
finding of fact and law. The award of the arbitrators shall be final and binding
on the parties from which no appeal may be taken, and an order confirming the
award or judgment upon the award may be entered in any court having
jurisdiction. The award of the arbitrators may include pre-award interest and
equitable relief to the extent the arbitrators deem appropriate. The parties
agree that the award of the arbitrators shall be the sole and exclusive remedy
between them regarding any Dispute presented to the arbitrators; that any
monetary award shall be made payable promptly and free of any deduction or
offset (except such amount, if any, as may be awarded by the arbitrators in
respect of counterclaims brought in the same proceedings); and that any costs or
fees incident to enforcing the award shall, to the maximum extent permitted by
law, be charged against the party resisting such enforcement.

              (e) The arbitrators, in the award, may assess the fees and
expenses of the arbitrators and the Proceeding, and the witness and attorneys'
fees of the parties, or any part thereof, against either or both parties, taking
into account the circumstances of the case. Except as assessed by the
arbitrators in the award, the fees and expenses of each arbitrator appointed by
a

                                     A-I-53
<PAGE>

party shall be borne by such party and the fees and expenses of the Proceeding
and of the third arbitrator shall be divided equally between the parties.

              (f) Prior to the appointment of the arbitrators, either party may
seek provisional remedies, including, without limitation, temporary restraining
orders and preliminary injunctions. After the appointment of the arbitrators,
the arbitrators shall have sole authority to grant such provisional remedies as
the arbitrators, in their sole discretion, deem necessary and appropriate.

              (g) Notwithstanding anything to the contrary in this Section
12.12, the parties expressly agree that either party may seek provisional
relief, including without limitation to temporary restraining orders and
preliminary injunctions, in addition to the remedy of arbitration set forth
herein. Any such action for relief shall not constitute a waiver of the right to
arbitrate.

              (h) In addition, notwithstanding the foregoing, if either party is
required to defend or prosecute third party claims in courts having jurisdiction
over such matters, neither party shall be precluded from fully exercising its
rights against the other party in such court with respect to such matters.
