                                  ARTICLE III

calculated as follows:

                  The amount received or deemed (as described below) to be
         received on the sale of the Actuator Business (which is defined as the
         business presently carried on by Company consisting of the design
         services, prototype development and production of actuators and related
         mechanical devices used in missiles and other projectiles in the
         defense industry but not including the electro-optics products or

                  (1) the face amount of the Actuator Liabilities (which are
         defined as all liabilities of or pertaining to the Actuator Business
         accruing from time to time on or after August 18, 1995) as at the date
         of sale except liabilities not otherwise assumed by the purchaser of
         the Actuator Business;



                                       6



                  (2) all federal, state and local taxes paid or payable whether
         on account of income or sales taxes paid or payable on the sale of die
         Actuator Business by Company;

                  (3) any and all third party coats reasonably incurred by
         Company in connection with the sale of the Company business including
         commissions and legal fees; and

                  (4) the amount of a reasonable reserve on account of any
         liabilities, claims or losses arising by reason of a breach of any
         representation or warranty granted by Company in connection with the
         sale of the Actuator Business.

                  An amount shall be deemed received for purposes of the
         definition of Net Proceeds of Sale under the following circus:

                           If the Actuator Business has not been sold by Company
         on or before April 30, 2000, Company shall have the right at any time
         thereafter to offer to sell the Actuator Business to Al Voigt, Judy
         Voigt, John Speicher, Gene Langworthy and Ed Levine (the
         "Shareholders") at a price (which shall be payable in cash at the
         closing) and on other tams as Company may specify. Such offer shall be
         open for acceptance for a period of 60 days. If one or more of the
         Shareholders elects to purchase his or its pro rata proportion of the
         Actuator Business and one or more of the Shareholders declines to elect
         to so purchase, the Shareholders electing to so purchase shall have a
         further right and option, exercisable by notice in writing within 30
         days of being notified by Company that one or more of the Shareholders
         has declined to so purchase, to purchase the pro rata proportion of the
         Actuator Business which no Shareholder has elected to purchase.
         Notwithstanding that one or more Shareholders has elected to purchase
         from Company a pro rata proportion of the Actuator Business, the right
         of any of the Shareholders to acquire the Actuator Business shall be
         null and void and, for purposes of entitlement to Net Proceeds of Sale,
         the Actuator Business shall be deemed to have been sold in cash at the
         price specified in the offer of Company.

                           If the Actuator Business has not been sold by Company
         on or before April 30, 2000, the Shareholders pro rata or such fewer
         number of Shareholders who have the unanimous consent of all of the
         Shareholders to make the offer contemplated in this paragraph (such
         Shareholders making the offer being herein referee to as the "Offering
         Shareholders") shall have the right at any time thereafter to offer to
         purchase the Actuator Business from Company on terms and conditions set
         forth immediately below. Such offer shall be open for acceptance for 60
         days. If Company accepts the offer within such 60 day period, the offer
         of the Offering Shareholders shall be completed by Company and the
         Shareholders in accordance with its terms. If the offer of the Offering
         Shareholders is not accepted, for purposes of entitlement to Net
         Proceeds of Sale, the Actuator Business shall be deemed to have been
         sold at the price specified in the offer of the Offering Shareholders.

                                Terms:



                                       7


                                a. the purchase price shall be paid in cash or
         by bank draft on closing;

                                b. the closing shall occur not more than 90 days
         following the acceptance of the offer;

                                c. the offer shall provide for the assumption by
         the Shareholders of the Actuator Liabilities and the Shareholders shall
         jointly and severally indemnify Company from any claims in respect
         thereof or provide security therefor acceptable to Company acting
         reasonably;

                                d. Company shall be released from any guarantees
         which it has with respect to indebtedness which comprises a portion of
         the Actuator Liabilities;

                                e. Company shall only represent and warrant the
         nature and extent of and title to the assets of the Actuator Business,
         its power and authority to convey the Actuator Business, that the
         financial statements most recently prepared present fairly the assets
         and liabilities of the Actuator Business and the results of its
         operations, that since the date of the last financial statement, and
         the business has been carried on in the ordinary course of business;
         and

                                f. Company shall undertake not to compete with
         the Actuator Business pursuant to an agreement substantially similar to
         the non-competition agreements entered into by Voigt and Speicher.

                  For purposes of determining the time of receipt of Net
         Proceeds of Sale, in the case of consideration paid for the Actuator
         Business otherwise than in cash, Net Proceeds of Sale shall only be
         deemed to be received once the non-cash consideration is converted into
         cash, which, in the event the non-cash consideration is not divisible,
         shall occur as soon as Company has converted it into cash or, if such
         is not possible within 30 days after receipt thereof Company shall have
         such non-cash consideration valued by a third-party appraiser and the
         amount of the appraisal shall be considered to be cash for purposes of
         determining the amount to be received by the shareholders. In the event
         that the non-cash consideration is divisible in half such that 50% of
         the non-cash consideration could be dealt with separately, Company
         shareholders holding more than 50% of the Company Common Stock
         immediately prior to the Merger (the "Company Shareholders") shall be
         entitled to direct how the divisible 50% of the non-cash consideration
         is to be converted to cash.

                  If there is a dispute or advice is required as to the
         calculation or allocation of Net Proceeds of Sale or as to the timing
         of the receipt thereof, the dispute shall be revolved by a firm of
         chartered accountants (who may be Wescam's auditors) appointed by
         Wescam and acceptable to the Company Shareholders. Such chartered
         accountants shall have for such purposes access to all necessary
         records of Company and such resolution shall be binding upon Wescam,
         and the Company Shareholders.



                                       8


                  In the event a reserve is taken in the calculation of Net
         Proceeds of Sale as contemplated by the definition thereof, 50% of the
         remaining amount of such reserve, if any, shall be distributed to the
         Company Shareholders pro rata or in such other proportions as they may
         unanimously direct in writing, following the termination of survival of
         such representations and warranties in respect of which the reserve has
         been taken.

         The foregoing subsections (i), (ii) and (iii) collectively, are
referred to herein as the "Merger Consideration". All such shares of any Company
Common Stock, when so converted, shall no longer be outstanding and shall
automatically be cancelled and retired and shall cease to exist, and each holder
of a certificate representing any such shares shall cease to have any rights
with respect thereto, except the right to receive the consideration provided in
this Section 3.1(c) to be issued or paid in consideration therefor upon the
surrender of such certificate in accordance with the Agreement, without
interest.

                  (d) Dissenters' Rights. If holders of Company Common Stock are
entitled to dissenters' rights in connection with due Merger under Chapter 13 of
the GCL, any Dissenting Shares shall not be converted into the Manger
Consideration, but shall be converted into the right to receive such
consideration as may be determined to be due with respect to such Dissenting
Shares pursuant to the laws of the State of California.

                  (e) Fractional Shares. No certificate or scrip representing
fractional Common Shares shall be issued upon the surrender for exchange of
certificates representing Company Common Stock, and such fractional share
interests will not entitle the owner thereof to vote or to enjoy any other
rights of a shareholder of Wescam or Jefferson.

         3.2 No Further Ownership Rights In Company Common Stock. All Common
Shares issued upon the surrender for exchange of shares of Company Common Stock
in accordance with the terms hereof shall be deemed to have been issued in full
satisfaction of all rights pertaining to such shares of Company Common Stock,
subject, however, to due Surviving Corporation's obligation to pay any dividends
or make any other distributions with a record date prior to the Effective Date
which may have been declared or made by Company on such shares of Company Common
Stock in accordance with the terms of this Merger Agreement and the Agreement or
prior to the date hereof and which remain unpaid at the Effective Date, and
there shall be no further registration of transfers on the stock transfer books
of the Surviving Corporation or its transfer agent of the shares of Company
Compare Stock which were outstanding immediately prior to the Effective Date.
If, after the Effective Date, certificates representing Company Common Stock are
presented to the Surviving Corporation for any reason, they shall be cancelled
and exchanged as provided in this Article III.

                                   ARTICLE IV
