following termination of employment of the Officer shall vest and become
exercisable for a period of twelve months following termination of employment.
The previously vested component of the stock options granted pursuant to Section
2(C) of this Agreement and the ISO Agreement shall remain intact and lapse only
if not exercised by the Officer within the prescribed twelve-month period for
exercise contained in the stock option agreement.

     6.  Noncompetition, Confidentiality and Inventions Agreement.  The Officer
         --------------------------------------------------------

reference.

     7.  Governing Law.  This Agreement shall be governed by and construed in
         -------------                                                       
accordance with the internal laws of the Commonwealth of Massachusetts and shall
be deemed to be performable in the Commonwealth of Massachusetts.

     8.  Severability.  In case any one or more of the provisions contained in
         ------------                                                         
this Agreement for any reason shall be held to be invalid, illegal or
unenforceable in any respect, such invalidity, illegality or unenforceability
shall not affect any other provision of this Agreement, but this Agreement shall
be construed, revised, modified and reformed to the maximum extent possible to

     9.  Waivers and Modifications.  This Agreement may be modified, and the
         -------------------------                                          
rights and remedies of any provision hereof may be waived, only as mutually
agreed by the parties and by a writing signed by both parties.  No waiver by
either party of any breach by the other or any provision hereof 

                                      -3-

waiver of any other provision of this Agreement. This Agreement, the
Noncompetition, Nondisclosure and Inventions Agreement previously signed by the
Officer, the Non-Qualified Stock Option Agreement and the ISO Agreement set

to the subject matter set forth herein and may not be waived, changed,

his rights or delegate any of his duties or obligations under this Agreement.

the designated beneficiary of the Officer if the Officer dies or becomes
permanently disabled following termination of employment.  Similarly, if the
Officer dies or becomes permanently disabled during or following termination of
employment, the estate or designated beneficiary of the Officer shall be
entitled to exercise any stock options granted to the Officer under this
Agreement to the same extent that the Officer would otherwise be entitled to
exercise such stock option.

          -----------                                                           
or relating to this Agreement shall be submitted for settlement to an arbitrator
agreed upon by the parties.  The decision of such arbitrator shall be final and
