         2. Due to  business  conditions,  the Company is required to reduce its
workforce.  Such  action is  subject  to the Worker  Adjustment  and  Retraining
Notification  Act (WARN) which requires the Company to provide 60 days notice to
employees  affected  by this  action.  As a result,  the  Company has decided to
terminate  Employee's  employment  pursuant  to  the  terms  of  the  Employment
Agreement.  It is the desire of the Company and Employee that  Employee  receive
those certain  benefits that are described in the Employment  Agreement and that
he would not  otherwise  be  entitled  to receive  upon his  termination  and to
resolve  any  claims  that  Employee  has  or  may  have  against  the  Company.
Accordingly, Employee and the Company agree as set forth below.

         3.The Company and Employee agree that  Employee's  employment  with the
Company will terminate on September 20, 1998 (the  "Termination  Date") the last
day of the 60-day notice period described above.

understands  and  acknowledges  that he shall not be entitled to any payments or
benefits from the Company other than those expressly set forth in this paragraph

         5.   Employee   and  his   successors   release  the  Company  and  its
shareholders,  investors,  directors,  officers,  employees,  agents, attorneys,
legal successors and assigns of and from any and all claims,  actions and causes

time had,  or shall or may have  against  the  released  parties  based  upon or

during the course of his employment with the Company.

         6.  Employee  acknowledges  that he has read  section 1542 of the Civil
Code of the State of California, which states in full:

A general release does not extend to claims, which the creditor does not know or
suspect to exist in his favor at the time of  executing  the  release,  which if
known by him must have materially affected his settlement with the debtor.

Employee waives any rights that he has or may have under section 1542 and/or any
similar law of any other state to the full  extent  that he may  lawfully  waive
such rights pertaining to this general release of claims, and affirms that he is
releasing  all known and  unknown  claims  that he has or may have  against  the
parties listed above.

any of the terms of this Agreement to anyone other than his immediate  family or
counsel,  except  as such  disclosure  may be  required  for  accounting  or tax
reporting  purposes or as  otherwise  may be required by law.  Employee  further
agrees  that he will  not,  at any  time in the  future,  make any  critical  or
disparaging statements about the Company, its products or its Employees,  unless

process.

Agreement,  the  prevailing  party shall be entitled to recover  from the losing
party its  reasonable and customary  attorneys'  fees and costs incurred in that
action.  Provided that, for clarity,  the parties acknowledge that neither party
will be required hereunder to advance any such fees and costs.
