                           original purchase price plus the documented costs of

                           employment with the Company and, provided you remain
                           employed by the Company, 33% of the remaining shares
                           will vest upon each of your next two anniversary
                           dates with the Company. If your employment is
                           terminated without cause at any time prior to your
                           third anniversary of employment, such options shall
                           vest for the full employment year in which the
                           termination without cause occurs and you will have a
                           period of three years from the date of any
                           termination without cause at any time, to exercise
                           such options. You may be eligible to receive such
                           future stock option grants as the Board shall, from
                           time to time, deem appropriate. Irrespective of this
                           Agreement and except for the above provisions
                           regarding vesting and exercise of options, all
                           options will be governed by the terms and conditions
                           set forth in the Company's 1994 Stock Option Plan
                           (whether or not granted under such plan).

                  (g)      The Company shall pay or reimburse you for all
                           reasonable expenses you incur moving your household
                           goods to the Boston Metropolitan area from the
                           Rochester, New York area, including your reasonable
                           travel expenses associated with the move.

                  (h)      Because of the necessity to conserve the Company's
                           cash resources in the initial periods of your
                           employment, you and the Company agree that if you
                           remain employed by the Company after April 30, 1998,
                           the Company shall pay you a retention bonus of
                           $450,000 on May 15, 2000. In the event your
                           employment terminates after April 30, 1998 but before
                           April 30, 2000, you will receive a retention payment
                           on May 15, 2000 which is equal to the $450,000
                           reduced by $18,750 per month for 
   3
                           each full month between your termination date and
                           April 30, 2000. Such payment shall be in addition to
                           the base salary of $50,000 per year. You understand
                           that the retention bonus shall be an unsecured
                           obligation of the Company and you are willing to risk
                           that the Company's financial position is such that it
                           will be able to make the payment due on May 15, 2000.

         3.       You will be elected to serve as a member of the Board at the
