                                   AMENDMENT

     Kopin Corporation (the "Company"), pursuant to authority reserved in
Section 18 of the Amended and Restated 1992 Stock Option Plan of the Company, as
amended (the "1992 Plan"), hereby amends the 1992 Plan as follows:

     Effective as of July 12, 2000, Section 5 of the 1992 Plan is deleted in its
entirety and is replaced with the following:

     5.   Stock Subject to the Plan.  The Plan covers 15,000,000 shares of
          -------------------------
     Stock; provided, that the number of shares purchased pursuant to the
            --------
     exercise of Options granted under the Plan and options granted under the
     Old Plan and the number of shares subject to outstanding Options granted
              ---
     under the Plan and options granted under the Old Plan shall be charged
     against the shares covered by the Plan; but shares subject to Options
     granted under the Plan or options granted under the Old Plan which
     terminated without being exercised shall not be so charged. Shares to be
     issued upon the exercise of Options granted under the Plan may be either
     authorized but unissued shares or shares held by the Company in its
     treasury. If any Option granted under the Plan or any option granted under
     the Old Plan expires or terminates for any reason without having been
     exercised in full, the shares not purchased thereunder shall again be
     available for Options thereafter to be granted. The number of shares of
     Stock covered by the Plan shall be subject to adjustment as provided in
     Section 15 hereof. No person may be granted in any calendar year an option
     or options to purchase more than 1,600,000 shares of Stock under the Plan.

     IN WITNESS WHEREOF, the Company has adopted this Amendment as of the 12th
day of July, 2000.

     (S)8.  Covenant Not to Compete.
            -----------------------

          (a) The Employee recognizes that the Employer is engaged in the
development and sale of III-IV compounds used in semiconductors and related
products in Massachusetts and throughout the United States and the world and in
the development of liquid crystal electronic imaging devices and display
products based thereon (collectively, the "Principal Business").  In the event
of the termination of the Employee's employment hereunder, voluntarily or for
cause (as defined in Section 8(d) below) and so long as the Employer is not in
breach of its obligations to the Employee hereunder, the Employee agrees that,
for a period of twelve (12) months from the date of such termination, he will
neither

          (i)  engage in the Principal Business directly for himself, or in
               conjunction with or on behalf of any commercial entity, or

          (ii) work as an employee in the Principal Business for any commercial
               entity,

where either (A) the Employee's duties in the course of any such activities
would be substantially similar to those he has performed for the Employer
hereunder or (B) the Employee's duties in the course of such activities would
involve disclosure or use of any confidential or proprietary information
relating to the business of the Employer which he may in any way acquire by
reason of his employment by the Employer.  The Employee's obligation under this
Section 8 shall extend to all geographical areas of the United States and the
world in which the Employer, as set forth above, carries on business, either
directly or indirectly, including, but not limited to, places where the Employer
has a place of business, has employees or representatives, or has advertised or
sold any products during the time period specified in this section.

          (b) The Employee further agrees that for a period of twelve (12)
months from the date of such termination, he will not on behalf of himself or
any commercial competitor of the Employer, compete for, or engage in the
solicitation of, with respect to the Company's products or services, any
commercial customer of the Employer, that he has, during the one year
immediately preceding such termination, solicited or serviced on
<PAGE>

                                      -5-

behalf of the Employer or that has been so solicited or serviced, during such
period, by any person under the Employee's supervision.

          (c) In the event of any violation of the foregoing provisions of this
Section 8, the Employer shall be entitled, in addition to any other rights or
remedies it may have, to injunctive relief, it being agreed that the damages
which the Employer would sustain upon any such violation are difficult or
impossible to ascertain in advance and that the Employee's violations may cause
irreparable harm to the Employer.

          (d)  The term "cause" shall mean termination due to an act or acts by
the Employee in willful contravention of the written directions of the Board of
Directors of the Employer.
