The aggregate rights delineated above of the holders of Common Stock to receive
DRS Stock or cash shall be referred to herein as the "Merger Consideration."

     (b) Shares of Subsidiary. None of the issued shares of Subsidiary shall be
converted as a result of the merger, but all of such shares shall remain issued
shares of capital stock of the Surviving Corporation.

     (c) Exchange of Certificates; Delivery of Cash. As promptly as practicable
after the Effective Date, each holder of an outstanding certificate or
certificates that prior thereto represented Shares of the Company's Common Stock
shall surrender the same to the Subsidiary, 

                                      -7-


<PAGE>

as exchange agent for all such holders (the "Exchange Agent"), and such holders
shall be entitled upon such surrender to receive in exchange therefor either
certificates representing the number of whole shares of DRS Stock into which the
shares theretofore converted and/or cash, as provided above in Section 2.2(a).
Adoption of this Agreement by the Company's Shareholders shall constitute
ratification of the appointment of the Subsidiary as Exchange Agent. Following
the Effective Date and until so surrendered, each outstanding certificate that,
prior to the Effective Date, represented Shares of Common Stock, shall be deemed
for all corporate purposes to evidence either ownership of the number of whole
shares of DRS Stock into which the Shares of Common Stock represented thereby
prior to such Effective Date shall have been converted or a right to receive the
cash amount set forth in Section 2.2(a) above or both, as specified in Section
2.2(a). No interest shall be payable with respect to the payment of any
dividends or with respect to a cash payment. The holder of a fractional share
interest, as such, shall only be entitled to receive a cash distribution as
provided in Sections 2.2(a) and 2.2(d) and shall not be entitled to any
dividends, or to any distribution in the event of a liquidation, or to any
voting or other privileges of a shareholder of in respect of such fractional
share interest.

     (d) Fractional Shares. Fractional shares of DRS Stock will not be issued.
The Exchange Agent will hold for the account of each holder of a certificate or
certificates formerly representing Shares of the Company's Common Stock who
would otherwise be entitled to receive a fractional interest in a share of DRS
Stock, and upon surrender of such certificate or certificates shall deliver to
such holder (together with certificates representing the number of whole shares
of DRS Stock to which he may entitled as provided in Section 2.2(a)), a cash
distribution in lieu of such fractional share in the amount set forth in Section
2.2(a) above. No interest shall be payable with respect to payment of such cash
distribution. Any payment with respect to fractional shares is merely intended
to provide a mechanical rounding of, and is not separately bargained-for,
consideration.

     (e)Dissenters' Rights. Any Company Shareholder who shall have delivered a
written demand for appraisal of his/her Shares, as provided in Sections 1300 et
seq., of the California General Corporation Law (each a "Dissenting
Shareholder"), shall not be entitled to DRS Stock or cash pursuant to this
Agreement, unless and until the holder thereof shall have failed to perfect or
shall have effectively withdrawn or lost such holder's right to dissent from the
merger under the California General Corporation Law, and shall be entitled to
receive only the payment provided by Sections 1300, et seq., of the California
General Corporation Law with respect to such Shares. If any Dissenting
Shareholder shall fail to perfect or shall have effectively withdrawn or lost
the right to dissent, the Shares held by such Dissenting Shareholder shall
thereupon be deemed to have been converted into and to have become exchangeable
for, on the Effective Date, the right to receive DRS Stock or cash pursuant to
the Agreement. The Company shall give DRS (a) prompt notice of any written
demands for appraisal of any Shares, attempted withdrawals of such demands, and
any other instruments served pursuant to applicable law received by the Company
relating to the Dissenting Shareholder's rights of appraisal, and (b) the
opportunity to direct all negotiations and proceedings with respect to demand
for appraisal under the California General Corporation Law. The Company shall
not, except with the prior written consent of DRS, 


                                      -8-
<PAGE>

voluntarily make any payment with respect to any demands for appraisals of
Shares, offer to settle or settle any such demands or approve any withdrawal of
any such demand.

municipal or other governmental department, commission, board, bureau, agency or
instrumentality, domestic or foreign, affecting or relating to the business of

<PAGE>

Company has delivered to the Surviving Corporation complete and correct copies
of all such written agreements, contracts and commitments, together with all
amendments thereto, and accurate descriptions of all oral agreements listed in
Schedule 4.10(a). No reason exists that would not allow each such oral agreement
to become a written agreement, executed by the parties thereto and enforceable
against any party to such agreement who fails to execute such agreement. Each
such oral agreement is in compliance with the Statute of Frauds of the
jurisdiction governing such oral agreement. All such agreements, contracts and
commitments governed by this Section 4.10(a) are in full force and effect, are
enforceable by the Company against the other parties thereto in accordance with
their terms, and, except as disclosed in Schedule 4.10(a), to the knowledge of
the Company and the Company's Shareholders, there does not exist thereunder any
violation or any default or event or condition or course of dealing which, after
notice or lapse of time or both, would constitute a default thereunder on the
part of the Company, or any other party thereto or would provide a basis for any
creditor of the Company, or any party to such agreements, contracts or
commitments, to challenge the extent, validity or priority of the interest of
any other party to such agreements, contracts or commitments; to the knowledge
of the Company and the Company's Shareholders, consummation of the transactions
contemplated under this Agreement and the Transaction Documents shall not give
rise to any violation or any default or event or condition which, after notice
or lapse of time or both, would constitute a default thereunder on the part of
the Company, or any other party thereto or would provide a basis for any
creditor of the Company, or any party to such agreements, contracts or
commitments to challenge the extent, validity or priority of the interest of any
other party to such agreements, contracts or commitments. No agreement, contract
or commitment to which the Company is a party, or by which it or any of its
properties is bound, adversely affects or in the future may adversely affect the
business of the Company. No agreement, contract or commitment to which the
Company is a party, or by which it or any of its properties is bound, is in
conflict, whether by way of violation of any term or condition or by way of
default, with any other agreement, contract or commitment to which the Company
is a party, or by which it or any of its properties is bound. All agreements,
contracts or commitments with Affiliates of the Company, to which the Company is
a party or by which it or any of its properties is bound reflect terms no less
favorable to the Company than could be obtained from unaffiliated third parties.
The Company has no outstanding powers of attorney, except routine powers of
attorney relating to representation before governmental agencies or given in
connection with qualification to conduct business in another jurisdiction.

     (i) Government Contracts Compliance. The Company is not, and the

or quote submitted to the United States Government by the Company. The Company

the insurer, the type of coverage provided, the amount of the annual premium for
the current policy period, the amount of remaining coverage and deductibles and
the coverage period) of all policies and contracts of insurance held by the
Company and/or the employees currently or previously employed in the business
thereof. All premiums due thereon have been paid and, to the knowledge of the
Company and the Company's Shareholders, the Company and its Affiliates have
complied in all material respects with the provisions of such policies. To the
knowledge of the Company or each of the Company's Shareholders, such policies
(i) are sufficient for compliance with all requirements of law and are
substantially consistent with all (A) Contracts to which the Company is a party
and (B) leases, mortgages, deeds of trust and deeds to secure debt to which the
Company is a party, (ii) are reasonable in scope and amount, in light of the
risks attendant to the businesses and activities in which the Company is or has
been engaged and (iii) are comparable to coverage customarily maintained by
companies in similar lines of business and in similar localities. There is no
material default with respect to any provision contained in any such policy and
there has not been any failure to give any notice or present any claim under any
such policy in a timely fashion or in the manner or detail required by the
policy. Except as disclosed in Schedule 4.20, no notice of cancellation or
non-renewal with respect to, or disallowance of any claim under, any such policy
has been received; neither has the Company been refused insurance with respect
to its assets or operations, nor has its coverage been previously canceled or
materially limited, by any insurer to which it has applied for such insurance or
with which it has held insurance.

     SECTION 4.21. Sufficiency of Assets and Real Property.

     (a) The properties owned by or leased to the Company are adequate for the
conduct of the business of the Company. Except as disclosed in Schedule 4.21(a),
all of the Assets are suitable for the uses in which they are currently
employed, are in good operating condition and are free from any defects, except
such minor defects as do not interfere with the continued use of such properties
and equipment in the conduct of the normal operations of the business of the
Company, and the Assets include supplies of spare parts for the equipment and
machinery included in the Assets in amounts consistent with past practices.

     (b) None of the Assets or Real Property is used by the Company or any of
its Affiliates in connection with any business or enterprise other than the
business of the Company.

Company have been established for any purpose; no accumulation or use of the
Company's corporate funds or assets has been made without being properly
accounted for in the respective books and records of the Company; all payments
by or on behalf of the Company have been duly and properly recorded and
accounted for in their respective books and records; no false or artificial
entry has been made in the books and records of the Company for any reason; no
payment has been made by or on behalf of the Company with the understanding that
any part of such payment is to be used for any purpose other than that described
in the documents supporting such payment; and the Company has not made, directly
or indirectly, any illegal contributions to any political party or candidate,
either domestic or foreign. The Company has complied with the Foreign Corrupt
Practices Act of 1977, as amended, and the rules and regulations thereunder
("FCPA") and, in each case, has not made any payment to or on behalf of any
person with respect to which a deduction could be disallowed under Section
162(c) of the Code. Neither the IRS nor any other federal, state, local or
foreign government agency or entity has initiated or threatened any
investigation of any payment made by the Company of, or alleged to be of, the
type described in this Section 4.23 nor is there a basis in fact for such
investigation.

the future. Other than such agreements or arrangements, if any, or as further
disclosed on Schedule 4.24, there has been no transaction between the Company
and any shareholder, officer, director or employee (or immediate family member

benefit of, any such shareholder, officer, director or employee (or immediate
family member of any thereof). Except as set forth in Schedule 4.24, no
shareholder, officer, director or employee (or immediate family member of any
thereof) of the Company owns directly or indirectly, on an individual or joint
basis, greater than a 5% interest in, or serves as an officer, director or

     SECTION 4.26. Environmental Conditions and Governmental Authorizations.
Except as specified in Schedule 4.26:

          (a) All real property owned, leased, occupied or used by the Company
     is free from contamination from any Hazardous Materials. The Company has

     injunction, decree, order or judgment outstanding, nor any claim, suit,
     proceeding, citation, fine, penalty, directive, summons or investigation,
     pending or threatened, relating to the ownership, use, maintenance or
     operation of the Premises by any Person, or to alleged violation of
     Environmental Requirements, or to the suspected presence of Hazardous
     Material thereon, nor, to the knowledge of the Company and the Company's
     Shareholders after reasonable inquiry, does there exist any basis for such
     claim, suit, proceeding, citation, fine, penalty, directive, summons or
     investigation being instituted or filed.

          (c) There is not constructed, placed, deposited, stored, disposed of
     or located on any real property owned, leased, occupied or used by the
     Company any polychlorinated biphenyls ("PCBs") or transformers, capacitors,
     ballasts, or other equipment which contains dielectric fluid containing
     PCBs, or any asbestos.

          (d) Neither the Company nor any of the Company's Shareholders has any
     knowledge of any alleged liability for Environmental Damages of any alleged
     violation of Environmental Requirements asserted against any of the owners
     or occupants of any related property located in the vicinity of any of any
     real property owned, leased, occupied or used by the Company.

          (e) The Company has in its possession all permits required to operate
     in compliance with all Applicable Law, and the Company is presently in full
     and complete compliance with each of such permits.

     SECTION 4.27. Leases of Personal Property (a) Schedule 4.27(a) correctly
describes each lease under which the Company is the lessee of any personal
property (collectively, the "Personal Property Leases"). The property described

business of the Company. The Company has all right, title and interest of the

party. Other than any related consents listed in Schedule 4.27(a), no consent is
necessary for the assignment of any Personal Property Lease for the consummation
of this Agreement or any Transaction Document or the transactions contemplated
hereby or thereby.

     (b) No event has occurred which (with the passage any of time or the giving
of notice) would materially impair any right of the Company to exercise and
obtain the benefits of any options contained in any Personal Property Lease.
There is no substantial default or basis for acceleration or termination, nor
has any event occurred which (with the passage of time or the giving of notice)
would constitute such a default or result in or permit the acceleration of any
Personal Property Lease.

the Company shall, from time to time, execute and deliver such additional
instruments, documents, conveyances and assurances as requested by the Surviving
Corporation to confirm, assure and further the rights, purposes, effects and
obligations set forth herein.

     SECTION 7.2. Covenants of Certain of the Company's Shareholders.

     By signing this Agreement, Leedom and Mason each agree that neither such
Shareholder nor any of his or her Affiliates will own, manage, operate, join or
control, or participate in the ownership, management, operation or control of,
or assist in any manner with, or be connected with or have any interest in, as a
stockholder, agent, consultant, partner, director, officer, employee or
otherwise: (i) any business which develops, manufactures and markets and/or
sells within the United States any product or service developed, manufactured,
marketed and/or sold by the Company (or contemplated to be developed,
manufactured, marketed and/or sold by the Company in the reasonably foreseeable
future); or (ii) any entity which otherwise competes directly or indirectly with
the business of the Company, except that either of them may make passive
investments in a competitive enterprise the shares of which are publicly traded
if such investment constitutes less than one half of one percent of the equity
of such enterprise. This above-described covenant shall be effective for the
period beginning on the Effective Date under this Agreement and ending on the
second anniversary of the Effective Date; provided, however, that if the
employment of Leedom and/or Mason is terminated by the Surviving Corporation
without cause prior to such second anniversary, then such Shareholder(s)
terminated without cause shall be relieved of the above-described covenant on
the relevant termination date; and, provided further, that if Leedom and/or
Mason voluntarily terminate employment with the Surviving Corporation or if the
employment of Leedom and/or Mason is terminated by the Surviving Corporation
with cause, then the terms of the above-described covenant shall restrict the
terminated Shareholder(s) for one year following the termination date or until
the second anniversary of the Effective Date, whichever date occurs later. By
signing this Agreement, each of the Company's Shareholders agrees that each
shall not, directly or indirectly, in any capacity whatsoever:


                                      -41-
<PAGE>

          (a) hire or solicit for employment, directly or indirectly, any
     personnel of the Company in any capacity whatsoever (which shall be deemed
     to include, without limitation, any existing or prospective employee of the
     Company or any person who has been such an employee of the Company within
     one hundred fifty (150) days prior to the Effective Date);

          (b) attempt directly or indirectly to induce any such Company
     personnel to leave the employ of, or discontinue such person's business
     association with, the Company;

          (c) solicit, directly or indirectly, any client or account or bona
     fide prospective client or account of the Company; or

          (d) interfere with the business relationships, contractual or
     otherwise, between the Company and any of its customers, suppliers or
     employees.

     SECTION 7.3. Remedies.

     (a) Reasonableness of Restraints. Each of the Company's Shareholders hereby
acknowledges that: (i) he is fully familiar with the restrictions, restraints
and limitations imposed upon him in Section 7.2 hereof (collectively, the
"Restraints"); (ii) the Surviving Corporation would not undertake the
transactions contemplated hereunder without the imposition of the Restraints and
each agreement of the Company's Shareholders herein to abide by such Restraints;
(iii) the imposition upon each such Shareholder of the Restraints is necessary
for the reasonable, adequate protection of the business of the Company; and (iv)
each and every Restraint is reasonable with respect to its subject matter,
geographic area and length of time.

     (b) Injunctive Relief. Each of the Company's Shareholders acknowledges that
monetary damages alone will not adequately compensate the Company and/or the
Surviving Corporation in the event of a breach or a threatened breach by him of
the Restraints and therefore each of the Company's Shareholders hereby agrees
that in addition to all remedies available to the Surviving Corporations and/or
Company at law or in equity, the Surviving Corporation and/or Company shall be
entitled to interim restraints and permanent injunctive relief for the
enforcement thereof, and to an accounting and payment over of all receipts
realized by such of the Company's Shareholders as a result of such breach.

     (c) Extension of Period of Restraints. In the event that any of the
Company's Shareholders shall be in material violation of any Restraints, then
the time limitation therefor shall be extended for a period of time equal to the
period of time during which such breach or breaches occurred. In the event the
Surviving Corporation and/or the Company shall be required to seek relief in any
court or other tribunal, then the Restraints shall be extended for a period of
time equal to the pendency of such proceedings, including appeals, and excluding
any periods during which the court or other tribunal has ordered the Company's
Shareholders to honor the Restraints and such Company's Shareholders have
complied with such order.


                                      -42-
<PAGE>

     (d) Court Ordered Reduction of Restraints. In the event that any of the
restrictions, limitations or restraints contained in this Agreement are deemed
to be unreasonable or unenforceable by any court of competent jurisdiction, then
each party hereto agrees to submit to such reduction of said restrictions,
limitations or restraints as the court shall deem reasonable.

     SECTION 7.4. Public Disclosure.

     No party to this Agreement shall make an announcement of this Agreement or
the transactions contemplated hereby to the public or any third party (including
employees of the Company), other than with the express consent of the Surviving
Corporation, on the one hand, and the Company and the Company's Shareholders, on
the other hand, or as may be required by applicable laws or regulations.

     SECTION 7.5. Limitations on Transfers and Dispositions.

     (a) Each Company Shareholder covenants that following the Effective Date
such Company Shareholder will not transfer the shares of DRS Stock, if any, to
be received hereunder in violation of the Securities Act, the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), or the rules of the SEC
promulgated thereunder, including Rule 144 under the Securities Act, and unless
and until (i) there is then in effect a registration statement under the
Securities Act covering such proposed disposition and such disposition is made
in accordance with such registration statement or (ii) (A) such Company
Shareholder shall have notified DRS of the proposed disposition and shall have
furnished DRS with a detailed statement of the circumstances surrounding the
proposed disposition and (B) if reasonably requested by DRS, such Company
Shareholder shall have furnished DRS with an opinion of counsel, reasonably
satisfactory to DRS and its counsel, that such disposition will not require
registration of such shares under the Securities Act.

     (b) Each Company Shareholder severally agrees that he/she has no plan or
present intention to sell, transfer or otherwise dispose of a number of shares
of DRS Stock to be received in the merger that would reduce the number of shares
of DRS Stock owned by such Company Shareholder to a number of shares having, in
the aggregate, a value as of the Effective Date of less than fifty (50) percent
of the value of all of the Company Shares held by such Company Shareholder as of
the Effective Date. For purposes of the agreement set forth in this Section (b),
Dissenting Shareholder Shares, Company Shares exchanged for cash in lieu of
fractional shares of DRS Stock and Company Shares sold, exchanged or otherwise
disposed of prior to and in anticipation of the merger will be treated as
Company Shares held by such Company Shareholder as of the Effective Date.

Third Party Claims (subject to the limitations set forth herein), then the
Indemnifying Party shall be entitled, at its option, to assume and control the
defense of such Third Party Claim at its expense and through counsel of its
choice if it gives prompt notice of intention to do so to the Indemnified Party.
In the event the Indemnifying Party exercises its right to undertake the defense
against any such Third Party Claim as provided above, the Indemnified Party
shall cooperate with the Indemnifying Party in such defense and make available
to the Indemnifying Party, at the Indemnifying Party's expense, all witnesses,
pertinent records, materials and information in its possession or under its
control relating thereto as is reasonably required by the Indemnifying Party.
Similarly, in the event the Indemnified Party is, directly or indirectly,
conducting the defense against any such Third Party Claim, the Indemnifying
Party shall cooperate with the Indemnified Party in such defense and make
available to it all such witnesses, records, materials and information in its
possession or under its control relating thereto as is reasonably required by
the Indemnified Party. No such Third Party Claim, except the settlement thereof
which involves the payment of money only and for which the Indemnified Party is
totally indemnified by the Indemnifying Party, may be settled by the
Indemnifying Party without the written consent of the Indemnified Party (which
consent shall not be unreasonably withheld). Similarly, no Third Party Claim
which is being defended in good faith by the Indemnifying Party shall be settled
by the Indemnified Party without the written consent of the Indemnifying Party
(which consent shall not be unreasonably withheld).

     SECTION 8.4. Limitations on Indemnification.

     (a) Participation in indemnification. Notwithstanding anything in this
Agreement to the contrary, Leedom and Mason shall be jointly and severally
liable for the totality of indemnification obligations incurred under this
Agreement; Miller, on the other hand, shall be severally liable for the pro rata
share of such liability attributable to him on the basis of his percentage of
Share ownership immediately prior to the Effective Date; and Ito and Kindig
shall not be liable for Losses as indemnitors hereunder.

     (b) Upper Limit to Indemnification. Regardless of the totality of
indemnification obligations incurred under this Agreement, Leedom, Mason and/or
Miller shall not be required to indemnify Surviving Corporation and/or its
Affiliates in an aggregate amount greater than $524,898.00.

     (c) Insubstantial matters. In an effort to avoid disputes over numerous
small items, Surviving Corporation and the Company's Shareholders agree that the
Company and the Company's Shareholders shall not be liable for Losses hereunder
until the total of all such Losses equals or exceeds $15,000 (the "Basket");
provided, however, that once such Losses exceed the Basket, the Company and the
Company's Shareholders shall be liable for all Losses including the first
$15,000 of such Losses in the Basket.

     SECTION 8.5. Shareholders' Representatives. In connection with the
procedures set forth in Section 8.3 (General Indemnification Provisions only),
the Minority Shareholders confirm and agree that they will be represented by
Leedom and Mason jointly as


                                      -45-
<PAGE>

Minority Shareholders' representatives (the "Shareholders' Representatives")
appointed and acting pursuant hereto and empowered by each Minority Shareholder
to give and receive notices and communications; to compromise, defend,
participate in the defense of, release and prosecute claims; to admit liability;
to consent to the entry of any judgment; to negotiate, agree to and enter into
any settlement; to demand arbitration and comply with awards of arbitrators and
courts; and to take any and all actions necessary or appropriate in the judgment
of the Shareholders' Representatives for the accomplishment of any of the
foregoing. A decision by both of the Shareholders' Representatives shall
constitute a decision of all of the Company's Shareholders, and shall be final,
binding and conclusive on all of them, and Buyer may rely on any act, decision,
notice, consent or instruction of both of the Shareholders' Representatives as
being the act, decision, notice, consent or instruction of each and all of the
Company's Shareholders; provided, however, that if, for any reason, Leedom and
Mason cannot or have not acted in concert, then the Company's Shareholders
empower Leedom to act on their behalf and Buyer may rely on such act of Leedom.

                                   ARTICLE IX.

                                   TERMINATION

     SECTION 9.1. Termination of Agreement. This Agreement may be terminated and
the merger contemplated in Article II may be abandoned at any time prior to the
Effective Date:

          (a) By mutual written consent of the parties hereto; or

          (b) By the Subsidiary if the Effective Date shall not have occurred on
     or before October 15, 1996 unless a delay in the Effective Date occurs
     solely by reason of a delay in obtaining the required tax clearance
     certificate from the Franchise Tax Board of the State of California, in
     which case the Agreement shall continue until such Tax Clearance is
     obtained (subject to clauses (c) and (d) below); or

          (c) By the Subsidiary if the board of directors of the Subsidiary at
     any time determines in its business judgment that this Agreement is no
     longer in the best interests of the Subsidiary or its shareholders by
     reason of a material adverse change in the business or prospects of the
     Company or by reason of a delay in the Effective Date beyond December 1,
     1996 for any reason whatsoever; or

          (d) By the Subsidiary if, at any time in the course of the
     Subsidiary's legal, accounting, financial, operational or environmental due
     diligence investigation as to the business of the Company and the
     liabilities thereof (whether disclosed, undisclosed, direct, indirect,
     absolute, contingent, secured, unsecured, accrued or otherwise, whether
     known or unknown) including, without limitation, the Subsidiary's
     continuing review of the Schedules delivered by the Company and any other
     materials delivered to Subsidiary, whether prior or subsequent to the date
     hereof, it shall have become aware of any facts or circumstances that


                                      -46-
<PAGE>

     adversely affect the basis upon which Subsidiary determined to enter into
     the transactions contemplated hereby; or

          (e) By any party hereto if a court of competent jurisdiction (whether
     federal, state or foreign) or any governmental body or agency (whether
     federal, state or foreign) shall have issued an order, decree or ruling or
     taken any other action restraining, enjoining or otherwise prohibiting the
     transactions contemplated by this Agreement or any Transaction Document,
     and such order, decree, ruling or other action shall have become final and
     nonappealable.

     SECTION 9.2. Procedure and Effect of Termination. In the event of
termination of this Agreement and abandonment of the merger pursuant to Section
9.1, written notice thereof shall forthwith be given to the other party or
parties specifying the provision hereof pursuant to which such termination is
made and this Agreement shall forthwith become void and there shall be no
liability on the part of the parties hereto (or their respective officers,
directors or affiliates), except nothing herein shall relieve either party from
liability for any willful breach hereof and except that the provisions of the
Confidentiality Agreement entered into by the Company and DRS on May 7, 1996 and
the provisions of Section 11.2 dealing with payment of expenses shall survive
such termination. The parties shall consult with each other before any public
announcement of the termination, or of discussions regarding the termination, of
this Agreement is made.

                                   ARTICLE X.

<PAGE>

     10.2. Restrictions On Transfer.

     (a) Each Holder agrees not to make any disposition of all or any portion of
the Registrable Securities unless and until the transferee has agreed in writing
for the benefit of DRS to be bound by this Section 10.2, provided and to the
extent such Section is then applicable and:

          (i) There is then in effect a registration statement under the
     Securities Act covering such proposed disposition and such disposition is
     made in accordance with such registration statement; or

          (ii) Such Holder shall have: (A) notified DRS of the proposed
     disposition and shall have furnished DRS with a detailed statement of the
     circumstances surrounding the proposed disposition; and (B) if reasonably
     requested by DRS, furnished DRS with an opinion of counsel, reasonably
     satisfactory to the DRS, that such disposition will not require
     registration of such shares under the Securities Act.

     (b) Each certificate representing Registrable Securities shall (unless
otherwise permitted by the provisions of this Agreement) be stamped or otherwise
imprinted with a legend substantially similar to the following (in addition to
any legend required under applicable state securities laws):

          THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
          SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD OR
          TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL
          REGISTERED UNDER SUCH ACT OR UNLESS DRS HAS RECEIVED AN OPINION OF
          COUNSEL OR OTHER EVIDENCE, SATISFACTORY TO DRS AND ITS COUNSEL, THAT
          SUCH REGISTRATION IS NOT REQUIRED.

     10.3. Registration Of Securities.

     (a) For so long as the Holders' ability to transfer Registrable Securities
is restricted by the holding period imposed on such Holders by Rule 144, if DRS
shall determine to register any of its securities either for its own account or
the account of Other Stockholders exercising their respective demand
registration rights, other than a registration relating solely to employee
benefit plans, or a registration relating solely to a Rule 145 transaction, or a
registration on any registration form that does not contemplate secondary sales,
DRS will:

          (i) Promptly give to each Holder written notice thereof; and

          (ii) Use its reasonable best efforts to include in such registration
     (and any related qualification under blue sky laws or other compliance),
     and in any underwriting


                                      -49-
<PAGE>

     involved therein, all the Registrable Securities specified in a written
     request or requests, made by any Holder and received by DRS within twenty
     (20) days after the written notice from DRS described in Section 10.3(a)(i)
     is mailed or delivered by DRS. Such written request may specify all or a
     part of a Holder's Registrable Securities.

     (b) Underwriting. If the registration of which DRS gives notice is for a
registered public offering involving an underwriting, DRS shall so advise the
Holders as a part of the written notice given pursuant to Section 10.3(a)(i). In
such event, the right of any Holder to registration pursuant to this Section
shall be conditioned upon such Holder's participation in such underwriting and
the inclusion of such Holder's Registrable Securities in the underwriting to the
extent provided herein. All Holders proposing to distribute their securities
through such underwriting shall (together with DRS and the Other Stockholders
distributing their securities through such underwriting) enter into an
underwriting agreement approved by DRS and with the representative of the
underwriter or underwriters selected by DRS.

     (c) Procedures. Notwithstanding any other provision of this Section, if the
representative of the underwriters advises DRS in writing that market factors
require a limitation on the number of shares to be underwritten, the
representative may (subject to the limitations set forth below) exclude all
Registrable Securities from, or limit the number of Registrable Securities to be
included in, the registration and underwriting, DRS shall so advise all holders
of securities requesting registration, and the number of shares of securities
that are entitled to be included in the registration and underwriting shall be
allocated first to DRS and thereafter as set forth in Section 10.9. If any
Holder does not agree to the terms of any such underwriting, he shall be
excluded therefrom by written notice from DRS or the underwriter. Any
Registrable Securities or other securities excluded or withdrawn from such
underwriting shall be withdrawn from such registration. If shares are so
withdrawn from the registration and if the number of shares of Registrable
Securities to be included in such registration was previously reduced as a
result of market factors, DRS shall then offer to all persons who have retained
the right to include securities in the registration the right to include
additional securities in the registration in an aggregate amount equal to the
number of shares so withdrawn, with such shares to be allocated among the
persons requested additional inclusion in accordance with Section 10.9 hereof.

     10.3. Expenses Of Registration. All Registration Expenses incurred in
connection with any registration, qualification or compliance pursuant to
Section 10.3 hereof shall be borne by DRS; all Selling Expenses incurred in
connection with any registration, qualification or compliance pursuant to
Section 10.3 hereof shall be borne by the Holder(s) of Registrable Shares
participating in such registration, qualification or compliance.

     10.5 Registration Procedures. In the case of each registration effected by
DRS pursuant to this Agreement, DRS will keep each Holder advised in writing as
to the initiation of each registration and as to the completion thereof. At its
expense, DRS will use its reasonable best efforts to:


                                      -50-
<PAGE>

          (a) Prepare and file with the Commission such amendments and
     supplements to such registration statement and the prospectus used in
     connection with such registration statement as may be necessary to comply
     with the provisions of the Securities Act with respect to the disposition
     of securities covered by such registration statement;

          (b) Furnish such number of prospectuses and other documents incident
     thereto, including any amendment of or supplement to the prospectus, as a
     Holder from time to time may reasonably request;

          (c) Cause all such Registrable Securities registered pursuant
     hereunder to be listed on the American Stock Exchange or on each securities
     exchange on which similar securities issued by DRS are then listed; and

          (d) Provide a transfer agent and registrar for all Registrable
     Securities registered pursuant to such registration statement and a CUSIP
     number for all such Registrable Securities, in each case not later than the
     effective date of such registration.

     10.6. Indemnification.

     (a) DRS will indemnify each Holder, each of their legal counsel, and
accountants and each person controlling such Holder within the meaning of
Section 15 of the Securities Act, with respect to which registration,
qualification, or compliance has been effected pursuant to this Agreement, and
each underwriter, if any, and each person who controls within the meaning of
Section 15 of the Securities Act any underwriter, against all claims, losses,
damages, and liabilities (or actions in respect thereof) arising out of or based
on any untrue statement (or alleged untrue statement) of a material fact
contained in any prospectus, offering circular, or other document or based on
any omission (or alleged omission) to state therein a material fact required to
be stated therein or necessary to make the statements therein not misleading,
and will reimburse each such Holder, each such underwriter, and each person who
controls any such underwriter, for any legal and any other expenses reasonably
incurred in connection with investigating and defending any such claim, loss,
damage, liability, or action, provided that DRS will not be liable in any such
case to the extent that any such claim, loss, damage, liability, or expense
arises out of or is based on any untrue statement or omission (or alleged untrue
statement or omission) based upon information furnished to DRS by such Holder or
underwriter. The obligations of DRS hereunder shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability, or action if such
settlement is effected without the consent of DRS (which consent shall not been
unreasonably withheld).

     (b) Each Holder will, if Registrable Securities held by him are included in
the securities as to which such registration, qualification, or compliance is
being effected, indemnify DRS, each of its directors, officers, partners, legal
counsel, and accountants and each underwriter, if any, of DRS' securities
covered by such a registration statement, each person who controls DRS or such
underwriter within the meaning of Section 15 of the Securities Act, each other
such Holder and Other Stockholder, and each of their officers, directors, and
partners, and 


                                      -51-
<PAGE>

each person controlling such Holder or Other Stockholder, against all claims,
losses, damages and liabilities (or actions in respect thereof) arising out of
or based on any untrue statement (or alleged untrue statement) of a material
fact contained in any such registration statement, prospectus, offering
circular, or other document, or any omission (or alleged omission) to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, and will reimburse DRS and such Holders,
Other Stockholders, directors, officers, partners, legal counsel, and
accountants, persons, underwriters, or control person for any legal and any
other expenses reasonably incurred in connection with investigating or defending
any such claim, loss, damage, liability, or action, in each case to the extent,
but only to the extent, that such untrue statement (or alleged untrue statement)
or omission (or alleged omission) is made in such registration statement,
prospectus, offering circular, or other document in reliance upon and in
conformity with information furnished to DRS by such Holder. The obligations of
such Holder hereunder shall not apply to amounts paid in settlement of any such
claims, losses, damages, or liabilities (or actions in respect thereof) if such
settlement is effected without the consent of such Holder (which consent shall
not be unreasonably withheld).

     (c) Each party entitled to indemnification under this Section 10.6 (the
"Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of such a claim or any
litigation resulting therefrom, provided that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or any litigation resulting
therefrom, shall be approved by the Indemnified Party (whose approval shall not
unreasonably be withheld), and the Indemnified Party may participate in such
defense at such party's expense, and provided further that the failure of any
Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations under this Agreement, to the extent such
failure is not prejudicial. No Indemnifying Party, in the defense of any such
claim or litigation, shall, except with the consent of each Indemnified Party,
consent to entry of any judgment or enter into any settlement that does not
include as an unconditional term thereof the giving by the claimant or plaintiff
to such Indemnified Party of a release from all liability in respect to such
claim or litigation. Each Indemnified Party shall furnish such information
regarding itself or the claim in question as an Indemnifying Party may
reasonably request in writing and as shall be reasonably required in connection
with defense of such claim and litigation resulting therefrom.

     (d) If the indemnification provided for in this Section is held by a court
of competent jurisdiction to be unavailable to an Indemnified Party with respect
to any loss, liability, claim, damage, or expense referred to therein, then the
Indemnifying Party, in lieu of indemnifying such Indemnified Party hereunder,
shall contribute to the amount paid or payable by such Indemnified Party as a
result of such loss, liability, claim, damage, or expense in such proportion as
is appropriate to reflect the relative fault of the Indemnifying Party on the
one hand and the Indemnified Party on the other in connection with the
statements or omissions that resulted in such loss, liability, claim, damage, or
expense as well as any other relevant equitable considerations. The relative
fault of the Indemnifying Party and of the Indemnified Party shall be determined
by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact


                                      -52-
<PAGE>

or the omission to state a material fact relates to information supplied by the
Indemnifying Party or by the Indemnified Party and the parties' relative intent,
knowledge, access to information, and opportunity to correct or prevent such
statement or omission.

     (e) Notwithstanding the foregoing, to the extent that the provisions on
indemnification and contribution contained in the underwriting agreement entered
into in connection with an underwritten public offering are in conflict with the
foregoing provisions, the provisions in the underwriting agreement shall
control.

     10.7. Information By Holder. Each Holder of Registrable Securities shall
furnish to DRS such information regarding such Holder and the distribution
proposed by such Holder as DRS may reasonably request in writing and/or as shall
be reasonably required in connection with any registration, qualification, or
compliance referred to in this Agreement.

     10.8. Rule 144 Reporting. With a view to making available the benefits of
certain rules and regulations of the Commission that may permit the sale of the
Restricted Securities to the public with registration, DRS agrees to use its
reasonable best efforts to:

          (a) Make and keep public information regarding DRS available as those
     terms are understood and defined in Rule 144 under the Securities Act;

          (b) File with the Commission in a timely manner all reports and other
     documents required of DRS under the Securities Act;

          (c) So long as a Holder owns any Restricted Securities, furnish to the
     Holder forthwith upon written request a written statement by DRS as to its
     compliance with the reporting requirements of Rule 144, a copy of the most
     recent annual or quarterly report of DRS, and such other reports and
     documents so filed as a Holder may reasonably request in availing itself of
     any rule or regulation of the Commission allowing a Holder to sell any such
     securities without registration.

     10.9. Allocation Of Registration Opportunities. In any circumstance in
which all of the Registrable Securities and Other Shares requested to be
included in a registration on behalf of the Holders or Other Stockholders cannot
be so included as a result of limitations of the aggregate number of shares of
Registrable Securities and Other Shares that may be so included, the number of
Registrable Securities and Other Shares that may be so included shall be
allocated among the Holders and Other Stockholders requesting inclusion of
shares pro rata on the basis of the number of shares of Registrable Securities
and Other Shares held by such Holders and Other Stockholders; provided, however,
that such allocation shall not operate to reduce the aggregate number of
Registrable Securities and Other Shares to be included in such registration, if
any Holder or Other Stockholder does not request inclusion of the maximum number
of shares of Registrable Securities and Other Shares allocated to him pursuant
to the above-described procedure, the remaining portion of his allocation shall
be reallocated among those requesting Holders and Other Stockholders whose
allocations did not satisfy their requests pro rata on the basis of 


                                      -53-
<PAGE>

the number of shares of Registrable Securities and Other Shares held by such
Holders and Other Stockholders, and this procedure shall be repeated until all
of the shares of Registrable Securities and Other Shares which may be included
in the registration on behalf of the Holders and Other Stockholders have been so
allocated.

                                   ARTICLE XI.

                                  MISCELLANEOUS

shall be assigned by either party without the prior written consent of the other
party; provided, however, that Surviving Corporation can assign its obligations
hereunder to a corporate Affiliate thereof.
