     Copyright Designs and Patents Act 1988) in respect of any acts of the
     Company or any acts of third parties done with the Company's authority in

     person or use for his own benefit or the benefit of any person other than
     the Company or any Associated Company any benefits of any confidential
     information which may come to his knowledge in the course of his employment
     and the Executive shall during the continuance of his employment use his
     best endeavours to prevent the unathorized publication or misuse of any
     confidential information provided that such restrictions shall cease to
     apply to any confidential information which may enter the public domain
     other than through the default of the Executive.

          that a Change in Control of the Company could occur at some time in
          the future; (ii) that the uncertainty associated with such a
          possibility could result in the distraction of the Executive from his
          assigned duties and responsibilities; (iii) that it is in the best
          interests of the Company and its shareholders to assure the continued
          attention by the Executive to such duties and responsibilities without
          such distraction; and (iv) that the Executive must be able to
          participate in the assessment and evaluation of any proposal which
          could effect a Change in Control of the Company without the Executive
          being influenced in the exercise of his judgment by uncertainties
          regarding the Executive's future financial security.

                                       9

 
     (b)  A "Change in Control" of the Company shall occur if, after the date of
          this Agreement:

          (i)  any Unrelated Party (as hereinafter defined) becomes the
               beneficial owner, directly or indirectly, of thirty percent (30%)
               or more of the common stock of the Company issued and outstanding
               immediately prior to such acquisition and/or securities of the
               Company, computing such percentage as if such securities acquired
               had been converted and are issued and outstanding for the purpose
               of determining such percentage or, if any Unrelated Party is the
               beneficial owner of thirty percent (30%) or more of such
               securities at the date of this Agreement, such Unrelated Party
               acquires an additional ten percent (10%) or more of the shares of
               common stock of the Company and/or securities of the Company
               which may be converted into shares of common stock of the
               Company.

          (ii) the shareholders of the Company approve (x) any consolidation or
               merger of the Company in which the Company is not the continuing
               or surviving corporation or pursuant to which shares of the
               common stock of the Company are converted into cash, securities
               or other property, other than a merger of the Company in which
               the holders of the common stock of the Company immediately prior
               to the merger have the same proportionate ownership of common
               stock of the surviving corporation immediately after the merger,
               or (y) any sale, lease, exchange or other transfer (in one
               transaction or a series of related transactions) of all, or
               substantially all, of the assets of the Company, or (z) any plan
               or proposal for the liquidation or dissolution of the Company.

         (iii) a majority of the Board ceases to consist of Continuing
               Directors.  "Continuing Directors" shall mean members of the
               Board who either (1) are members of the Board at the date of this
               Agreement or (2) are nominated or appointed to serve as directors
               by a majority of the then Continuing Directors; or

          (iv) any tender or exchange offer is made to acquire thirty percent
               (30%) or more of the common stock of the Company, other than an
               offer made by the Company, and shares are acquired pursuant to
               that offer.

     (c)  "Unrelated Party" shall mean any party or group of parties acting
          together, excluding, however, the Company, a subsidiary of the Company
          and any trustee under any employee benefit plan maintained by the
          Company.

     (d)  Upon (x) the termination of the Executive by the Company without Cause
          following a Change in Control of the Company or (y) the Executive's
          voluntary termination of employment for Good Reason following a Change
          in Control of the Company prior to expiration of the then effective
          two (2) year period of employment, then the Company shall provide to
          the Executive, within thirty (30) days after the applicable event, the
          following benefits:

          (i)  in one lump sum a cash payment equal to the average annual
               salary, bonus and benefits paid to the Executive for the past two
               (2) years, multiplied by two (2).

          (ii) to the extent permitted by applicable law, inclusion in the
               Company's life and medical plans as if the Executive were still
               employed by the Company until the earlier of two (2) years from
               the date of his termination or until the Executive 

                                       10

 
               obtains eligibility under comparable employee plans, with the
               Company paying that portion of the premium which it was paying
               for the Executive at the time of his termination.

     (e)  Good Reason.   "Good Reason" shall mean:
          -----------                             

          (i)  without his express written consent, the assignment to the
               Executive of any duties inconsistent with his positions, duties,
               responsibilities and status with the Company as of the date of
               this Agreement or a change in his titles or offices as of same
               date, or any removal of the Executive from or any failures to re-
               elect the Executive to any of such positions, except in
               connection with the termination of his employment for Cause or as
               a result of his Disability or death, or termination by the
               Executive other than for Good Reason;

          (ii) any reduction of the then-existing base salary or a reduction of
               more than ten percent (10%) in the aggregate value of any benefit
               plans without the prior written consent of the Executive, which
               is not remedied within ten (10) calendar days after receipt by
               the Company of written notice from the Executive of such change
               or reduction, as the case may be;

         (iii) a determination by the Executive made in good faith that, as a
               result of a Change in Control of the Company and a change in
               circumstances thereafter significantly affecting his position, he
               has been rendered substantially unable to carry out, or has been
               substantially hindered in the performance of, any of the
               authorities, powers, functions, responsibilities or duties
               attached to his position immediately prior to the Change in
               Control of the Company, which situation is not remedied within
               thirty (30) calendar days after receipt by the Company of written
               notice from the Executive of such determination;

          (iv) failure by the Company to require any successor (whether direct
               or indirect, by purchase, merger, consolidation or otherwise) to
               all or substantially all of the business and/or assets of the
               Company, by agreement in form and substance satisfactory to the
               Executive, expressly to assume and agree to perform this
               Agreement in the same manner and to the same extent that the
               Company would be required to perform it if no such succession had
               taken place; or

          (v)  the Company shall relocate its principal executive office or
               require Executive to have his principal location of work or
               principal residence any location which is in excess of thirty
               miles from the location as of the date hereof; or

          (vi) any material breach of this Agreement by the Company.

12.9 The Executive shall not be required to mitigate the amount of any payments
     or benefit provided by this Agreement nor shall the amounts of any payment
     or benefit provided for by this Agreement be reduced by any compensation
     earned by the Executive as the result of employment by the Company or
     another employer either before or after a Change in Control of the Company.

12.10Nothing in this Agreement shall prevent or limit the Executive's
     continuing or future participation in any benefit, bonus, incentive or
     other plan or program provided by the Company or any of its affiliated
     companies and for which the Executive may qualify, nor shall anything
     herein limit or 

                                       11

 
     otherwise affect such rights as the Executive may have under any other
     agreements with the Company or any of its affiliated companies. Amounts
     which are vested benefits or which the Executive is otherwise entitled to
     receive under any plan or program of the Company or any of its affiliated
     companies at or subsequent to the termination of employment hereunder shall
     be payable in accordance with such plan or program.
