            A.   Effective as of the Closing, Seller will sell, convey,
transfer, assign and deliver to Purchaser, the Purchased Assets, free and
clear of all Encumbrances (other than as provided in the next sentence), and
Purchaser will acquire from Seller the Purchased Assets.  Purchaser shall
acquire the unbilled Accounts Receivable relating to Contracts subject only to
potential audit adjustments by the other party to each such Contract which may
reduce the amount of such unbilled Account Receivable (but no other
Encumbrances); provided that the Purchaser shall assume no monetary,
performance, warranty or other liability, or obligations relating to expired
Contracts awaiting closeout.

            B.   Purchaser shall not assume or acquire any obligation or
liability of Seller except, effective as of the Closing, the following:

                 (i)    all obligations and liabilities accruing, arising out
of, or relating to events or occurrences happening after the Closing under
Contracts identified on the Disclosure Schedule as being assumed by Purchaser
(but in any case, not including any obligation or liability for any breach
occurring prior to the Closing); and

                 (ii)   the Assumed Vacation Liability (not to exceed
$325,000.00 in the aggregate);

                 (iii)  Seller's Last Payroll; and

                 (iv)   all obligations specifically undertaken by Purchaser
pursuant to the other provisions of this Agreement.

      2.2   PURCHASE PRICE.  On the Closing Date, Purchaser shall make the
following payments and deliveries of documents, and shall assume the
designated liabilities in consideration for the sale, transfer, assignment,
conveyance and delivery of the Purchased Assets:

            (a)     the Deposit shall be paid to the Seller for the IRS, at
Purchaser's option, by wire transfer of immediately available funds or by
cashier's or certified check;

            (b)     the Initial Plan Payment shall be paid to the Plan, at
Purchaser's option, by wire transfer of immediately available funds or by
cashier's or certified check;

            (c)     the Employee Expense Liability (not to exceed $50,000.00
in the aggregate) shall be paid pro rata to Employees of the Seller holding
allowed claims for employee expenses;

            (d)     the other components of the Purchase Price which are
payable at the Closing shall be paid at Purchaser's option, by wire transfer
of immediately available funds or by cashier's or certified check;

            (e)  Purchaser shall make the Assigned Vacation Payment, the
Deferred Payments and the Assigned Non-Compete Payments on or before the
designated anniversaries of the Closing Date; and

            (f)   the Assumed Vacation Liability shall be assumed by
Purchaser, and, subject to the next sentence of this paragraph (f), shall be
paid or provided for in accordance with the Purchaser's existing vacation
policy.  Purchaser shall not be required to make any cash payment for Assumed
Vacation Liability within less than one year following the Closing Date, and
Purchaser shall not require that any cash payment for Assumed Vacation
Liability be paid for across a period greater than two years following the
Closing Date.

To the extent that Seller is liable as of the Closing Date to any governmental
agency or taxing authority whose consent or action is required for the
transfer of any Permit, Purchaser, at its election, may pay or provide for
payment of amounts due to such agency or authority and may deduct amounts paid
or required to be paid to such agency or authority from the Designated
Payment.  For the purpose of the foregoing sentence, the Seller shall be
considered liable if the taxing authority or governmental agency has a right
to payment that constitutes a "claim" against Seller within the meaning of
Section 101(5) of the Bankruptcy Code.  Notwithstanding subsection (b) of this
Section 2.2, in the event that a claim is allowed against Seller in favor of
any current or former employee of Seller as a priority claim under Sections
507(a)(3) or 507(a)(4) of the Bankruptcy Code before Closing, then the portion
of the Initial Plan Payment that is equal to the amount of such allowed
priority claims shall be paid to Seller, and not to the Plan, and the
remaining portion of the Initial Plan Payment shall be paid to the Plan.  All
payments to the Plan shall be made directly to T. Rowe Price as the
administrator of the Plan, or to the successor administrator of the Plan.

      2.3   CLOSING COSTS; TRANSFER TAXES.  The parties shall endeavor to
obtain exemptions under Section 1146 of the Bankruptcy Code and otherwise from
documentary transfer taxes and any other sales, use or other taxes imposed by
reason of the transfers of the Purchased Assets provided hereunder ("Transfer
Taxes").  To the extent that payment of a Transfer Tax is not subject to an
exemption, Purchaser shall be responsible for the payment of any such Transfer
Tax (provided, however, that Seller shall be responsible for the payment of
any Transfer Tax or other tax accruing or arising prior to the Closing).

      2.4   PURCHASE PRICE ALLOCATIONS.  At Closing, Seller and Purchaser
shall agree in writing to an allocation of the Purchase Price and shall
execute, and thereafter file on a timely basis with their respective federal
income tax returns, the initial asset acquisition statement and any
supplemental statements on Internal Revenue Service Form 8594 required by
Temporary Treasury Regulation Section 1.1060-1T.

      2.5   WAIVERS AND RELEASES OF CERTAIN CLAIMS.  At Purchaser's request,
at Closing, and thereafter from time to time, Seller shall waive and release
any and all claims, known and unknown, they, or any of them, have or may have,
as of the Closing Date, including without limitation Avoidance Claims, against
all Hired Employees.  Such release shall be a general release and shall be in
a form that is reasonably satisfactory to Purchaser and its counsel.

generally accepted accounting principles consistently applied, and contain and
reflect all necessary adjustments for a fair representation of the Financial
Statements as of the date and for the period covered thereby.

      4.9   LITIGATION.  There are no suits, actions, proceedings or
investigations pending or, to the best knowledge of Seller, threatened
(whether or not any such suit, action, proceeding or investigation involves,
or seeks recourse against, Seller or any of the Purchased Assets) ("Actions")
which materially affect or would, if adversely determined, materially
adversely affect any of the Purchased Assets or Seller's ability to execute
and deliver this Agreement or consummate the transactions contemplated hereby.

      4.10  LABOR MATTERS.  Seller is not a party to any labor agreement with
respect to its employees with any labor organization, group or association. 
Seller has not experienced any attempt by organized labor or its
representatives to make Seller conform to demands of organized labor relating
to its employees or to enter into a binding agreement with organized labor
that would cover the employees of Seller.  Seller is in material compliance
with all applicable laws respecting employment practices, terms and conditions
of employment and wages and hours and is not engaged in any unfair labor
practice.  There is no unfair labor practice charge or complaint against
Seller pending before the National Labor Relations Board or any other
governmental agency arising out of Seller's activities, and Seller has no
knowledge of any facts or information which would give rise thereto; there is
no labor strike or labor disturbance pending or threatened against Seller nor
is any grievance currently being asserted; and Seller has not experienced a
work stoppage or other labor difficulty.

      4.11  COMPLIANCE WITH LAW.  Seller and the conduct of its business are
in compliance with all applicable laws, statutes, ordinances, rules,
regulations and orders, whether federal, state or local (collectively, "Law"
or "Laws"), except where the failure to comply would not have a material
adverse effect on the business, financial condition or operations of Seller. 
Seller has not received any written notice to the effect that, or otherwise
been advised that, it is not in compliance with Law where the failure to
comply would have a material adverse effect on the business, financial
condition or operations of Seller, and Seller has no reason to anticipate that
any presently existing circumstances are likely to result in violations of any
such Law which would, in any one case or in the aggregate, have a material
adverse effect on the business, financial condition or operations of Seller. 
All Permits that are required by Law, or which are otherwise necessary or
appropriate for the operation and conduct of the business of Seller, are held
by Seller in its name, are in full force and effect.  Seller is in good
standing under, and in compliance with, all Permits.

      4.12  NO BROKERS.  Neither Seller nor any Affiliate has entered into or
will enter into any Contract, agreement, arrangement or understanding with any
person or firm which will result in the obligation of Purchaser to pay any
finder's fee, brokerage commission or similar payment in connection with the
transactions contemplated hereby.

      4.13  NO OTHER AGREEMENTS TO SELL THE ASSETS OR SELLER.  Neither Seller
nor any shareholder of Seller has any legal obligation, absolute or
contingent, to any other person or firm to sell the Purchased Assets, to sell
a majority of the capital stock of Seller or to effect any merger,
consolidation or other reorganization of Seller or to enter into any agreement
with respect thereto.

      4.14  PROPRIETARY RIGHTS.  All of Seller's Proprietary Rights are listed
in the Disclosure Schedule.  The Proprietary Rights listed in the Disclosure
Schedule are in all material respects all those used in the business of
Seller.  No person has a right to receive a royalty or similar payment in
respect of any Proprietary Rights pursuant to any contractual arrangement
entered into by Seller, and no person otherwise has a right to receive a
royalty or similar payment in respect of any such Proprietary Rights.  Seller
has no licenses granted by or to it or no other agreements to which it is a
party, relating in whole or in part to any of the Proprietary Rights. 
Seller's use of the Proprietary Rights is not infringing upon or otherwise
violating the rights of any third party in or to such Proprietary Rights, and
no proceedings have been instituted against or notices received by Seller that
are presently outstanding alleging that Seller's use of its Proprietary Rights
infringes upon or otherwise violates any rights of a third party in or to such
Proprietary Rights.

of Maryland (without reference to the choice of law provisions of Maryland
law)

      9.5   ENTIRE AGREEMENT; AMENDMENTS AND WAIVERS.  This Agreement,
together with all exhibits and schedules hereto and all agreements
contemplated hereby, constitutes the entire agreement among the parties
pertaining to the subject matter hereof and supersedes all prior agreements,
understandings, negotiations and discussions, whether oral or written, of the
parties and their employees, agents, representatives and attorneys.  No
supplement, modification or waiver of this Agreement shall be binding unless
executed in writing by the party to be bound thereby.  No waiver of any of the
provisions of this Agreement shall be deemed or shall constitute a waiver of
any other provision hereof (whether or not similar), nor shall such waiver
constitute a continuing waiver unless otherwise expressly provided.

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

      9.7   EXPENSES.  Except as set forth below or as otherwise specified
herein, each party hereto shall pay its own legal, accounting, out-of-pocket
and other expenses incident to this Agreement and to any action taken by such
party in preparation for carrying this Agreement into effect.  The obligations
of the parties under this Section shall survive termination of this Agreement.

      9.8   TITLES.  The titles, captions or headings of the Articles and
Sections herein are inserted for convenience of reference only and are not
intended to be a part of or to affect the meaning or interpretation of this
Agreement.

      9.9   FURTHER ASSURANCES.  Each party shall at any time and from time to
time hereafter, both before and after Closing, execute, acknowledge and
deliver to the other party any and all instruments or assurances that the
other party may reasonably require for the purpose of giving full force and

the other's reasonable requests made in aid of consummating the transactions
herein contemplated.

      9.10  SIGNED UNDER SEAL.  This Agreement is signed under seal by the

      9.11  TIME IS OF THE ESSENCE.  Time is of the essence under this

WITH RESPECT TO ANY CLAIM OR CAUSE OF ACTION ARISING UNDER OR IN CONNECTION
WITH THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

      9.14  PUBLICITY.  All notices to third parties and all publicity
concerning the transactions contemplated by this Agreement shall be jointly
planned and coordinated by and between Purchaser and Seller.  None of the
parties shall act unilaterally in this regard without the prior written
approval of the others; however, this approval shall not be unreasonably
withheld.

      9.15  REQUIRED FILINGS.  Seller shall file all documents and reports
required by Law in connection with the transactions contemplated by this
Agreement, including without limitation filings as may be required under
securities laws.

      9.16   CONFIDENTIALITY.  Each party hereto and its respective
accountants, attorneys, employees and other agents, will keep confidential all
information, oral and written, obtained from any other party hereto or its
affiliates and refrain from using in any manner all information obtained from
the others and not otherwise publicly available notwithstanding any
termination of this Agreement.  Seller shall not disclose or discuss the
existence or terms of this Agreement to or with any persons other than its
attorneys, accountants, financial advisors and such of its executives as may
be required to know same in implementing the provisions of this Agreement
(each of whom shall be instructed not to disclose such information), and
except as necessary in connection with any filing with the Bankruptcy Court
seeking approval of this Agreement.  The foregoing shall not prohibit any
other disclosure required by law, provided that the disclosing party shall use
its best efforts to consult with the others in advance of any such disclosure.

                                   ARTICLE X
                           POST-CLOSING OBLIGATIONS
                           ------------------------
      10.1  COVENANT NOT TO COMPETE.  Seller acknowledges and agrees that: 
(i) Seller's business is conducted in Montgomery County and Prince Georges
County, Maryland; (ii) Seller's reputation and goodwill are an integral part
of its business; (iii) if Seller deprives Purchaser of any of Seller's
goodwill or in any manner utilizes its reputation and goodwill in competition
with Purchaser, Purchaser will be deprived of the benefits it has bargained
for pursuant to this Agreement; and (iv) this covenant is necessary to
transfer the business and goodwill of Seller to Purchaser effectively. 
Accordingly, as an inducement for Purchaser to enter into this Agreement,
Seller agrees that for a period of three years after the Closing, Seller shall
not, without Purchaser's prior written consent, directly or indirectly, own,
manage, operate, join, control or participate in the ownership, management,
operation or control of, or be connected with, any, profit or nonprofit
business or organization either in Montgomery County or Prince Georges County,
Maryland, which involves high technology research or development, design or
fabrication of sensors or instrumentation, technical support services, or
software development.  Seller further agrees that it shall not solicit or
enter into any business or transaction with any person or entity that is a
party to any Project Contract for a period of three years after the Closing. 
Seller shall maintain in confidence, and not to disclose to any third party,
any ideas, methods, developments, inventions, improvements, trade secrets and
business plans and information which are confidential information of Seller. 
In the event the agreement in this Section 10.1 shall be determined by any
court of competent jurisdiction to be unenforceable by reason of its extending
for too great a period of time or over too great a geographical area or by
reason of its being too extensive in any other respect, it shall be
interpreted to extend only over the maximum period of time for which it may be
enforceable and/or over the maximum geographical area as to which it may be
enforceable and/or to the maximum extent in all other respects as to which it
may be enforceable, all as determined by such court in such action.

          Seller acknowledges that a breach of the covenants contained in this
Section 10.1 will cause irreparable damage to Purchaser, the exact amount of
which will be difficult to ascertain, and that the remedies at law for any
such breach will be inadequate.  Accordingly, Seller agrees that if Seller
breaches the covenant contained in this Section 10.1, in addition to any other
remedy which may be available at law or in equity, Purchaser shall be entitled
to specific performance and injunctive relief, without posting bond or other
security.

      10.2  INDEMNIFICATION BY THE SELLER.  Subject to Section 9.1 and the
further provisions of this Article X, the Seller shall protect, defend, hold
harmless and indemnify the Purchaser, its officers, directors, stockholders,
employees and agents, and their respective successors and assigns from,
against and in respect of any and all losses, liabilities, deficiencies,
penalties, fines, costs, damages and expenses whatsoever (including reasonable
professional fees and costs of investigation, litigation, settlement, and
judgment and interest) ("Losses") that may be suffered or incurred by any of
them arising from or by reason of any of the following.

            (a)  Any breach of any representation, warranty, covenant or
agreement made by the Seller, in this Agreement or contained in any
certificate executed by the Seller and delivered to the Purchaser in
connection with this Agreement;

            (b)  Any liability or obligation of the Seller which has not been
assumed by the Purchaser pursuant to the express provisions of this Agreement;
and

            (c)  Any and all costs and expenses (including reasonable legal
fees) incident to the enforcement of the provisions of this Section.

      10.3  INDEMNIFICATION BY THE PURCHASER.  Subject to Section 9.1 and the
further provisions of this Article X, from and after the Closing the Purchaser
shall protect, defend, hold harmless and indemnify the Seller, its officers,
directors, employees and agents, and stockholders and their respective
successors and assigns from, against and in respect of any all Losses that may
be suffered or incurred by any of them arising from or by reason of any of the
following.

            (a)  Any breach of any representation, warranty, covenant or
agreement made by the Purchaser in this Agreement or contained in any
certificate executed by the Purchaser and delivered to the Seller in
connection with this Agreement; and

            (b)  Any and all costs and expenses (including reasonable legal
fees) incident to the enforcement of the provisions of this Section.

      10.4  INDEMNIFICATION PROCEDURES.  Whenever a party hereto (such party
and each other Person which is entitled to indemnification pursuant to any
provisions of this Agreement, an "Indemnified Party") shall learn after the
Closing of a claim that, if allowed (whether voluntarily or by judicial or
quasi-judicial tribunal or agency), would give rise to an obligation of
another party (the "Indemnifying Party") to indemnify the Indemnified Party
under any provision of this Agreement, before paying the same or agreeing
thereto, the Indemnified Party shall promptly notify the Indemnifying Party in
writing of all such facts within the Indemnified Party's knowledge with
respect to such claim and the amount thereof (a "Notice of Claim").  If, prior
to the expiration of fifteen (15) days from the mailing of a Notice of Claim,
the Indemnifying Party shall request, in writing, that such claim not be paid,
the Indemnified Party shall not pay the same, provided the Indemnifying Party
proceeds promptly, at its or their own expense (including employment of
counsel reasonably satisfactory to the Indemnified Party), to settle,
compromise or litigate, in good faith, such claim.  After notice from the
Indemnifying Party requesting the Indemnified Party not to pay such claim and
the Indemnifying Party's assumption of the defense of such claim at its or
their expense, the Indemnifying Party shall not be liable to the Indemnified
Party for any legal or other expense subsequently incurred by the Indemnified
Party in connection with the defense thereof.  However, the Indemnified Party
shall have the right to participate at its expense and with counsel of its
choice in such settlement, compromise or litigation.  The Indemnified Party
shall not be required to refrain from paying any claim which has matured by a
court judgment or decree, unless an appeal is duly taken therefrom and
execution thereof has been stayed, nor shall the Indemnified Party be required
to refrain from paying any claim where the delay in paying such claim would
result in the foreclosure of a lien upon any of the property or assets then
held by the Indemnified Party.  The failure to provide a timely Notice of
Claim as provided in this Section shall not excuse the Indemnifying Party from
its or their continuing obligations hereunder; however, the Indemnified
Party's claim shall be reduced by any damages to the Indemnifying Party
resulting from the Indemnified Party's delay or failure to provide a Notice of
Claim as provided in this Section.

      10.5  ALLEGATIONS BY THIRD PARTIES.  For purposes of this Article X, any
assertion of fact and/or law by a third party that, if true, would constitute
a breach of a representation or warranty made by a party to this Agreement or
make operational an indemnification obligation hereunder, shall, on the date
that such assertion is made, immediately invoke the Indemnifying Party's
obligation to protect, defend, hold harmless and indemnify the Indemnified
Party pursuant to this Article X.

      10.6  CLOSEOUT OF EXPIRED CONTRACTS.  From and after the Closing,
Purchaser shall complete documentation required for closeout of each of the
expired Contracts designated on the Disclosure Schedule and shall take all
actions reasonably required to obtain closeout on each such Contract;
provided, however, that Purchaser shall not be required to assume any
monetary, performance, warranty or other liability or obligation of Seller
under any such Contract.
