            a.)   New or transferred members of this plan will participate on a
                  pro-rata basis starting the first full calendar quarter of
                  participation in the plan. Calendar quarters are defined in
                  the annual Vicor Fiscal Calendar.

            b.)   Participants who resign or are terminated for cause from Vicor
                  within a quarterly incentive period will terminate all
                  participation in the plan, retroactive to the beginning of
                  that period.

            c.)   Participants terminated by Vicor without cause, transferred or
                  retired, will be considered for incentive on a pro-rata basis
                  within an incentive period at the time determination of sales
                  incentive is made.

III.  INCENTIVE:

      A.    Sales incentive will be granted at the rate of 2% of "Net Billings
            Delta" times the Gross Margin as calculated, by sales territory at
            the end of each incentive period.

            a.)   Each participant will be given a Quarterly Billings Plan
                  approved by the Senior Vice President of Sales. This will be
                  based on the previous year's net sales billed, less
                  exclusions.

                 1.)   Assume 1995 Net Billings of $7,000K

                 2.)   1996 Quarterly Billings goal is $1,750K

                 3.)   Q1 1996 Net Billings are $2,250K, Gross Margin is 45%
                       $2,250 - $1,750K = $500K x (.02 x .45) = $4,500 incentive
                       Q2 Billings are $1,500K
                       No commission would be paid, ($250K) would be carried
                       forward and added to Q3
                       Q3 1996 Billings, $3,000K, net, Gross Margin is 47%
                       $3,000K - $1,750K - $250K = $1,000K
                       $1,000K x (.02 x .47) = $9,400

      A.    Billings Plan - the amount of Net Billings in a territory during the
            plan year, normally similar to the previous year's Billings, divided
            by four, will establish the base quarterly quota for the incentive
            year.

            a.)   Sales resulting from very little or no effort on the part of
                  the participant may be classified as a "windfall" and may be
                  excluded in whole, in part, or not at all, at the discretion
                  of the Senior Vice President of Sales.

            b.)   Consideration may be given to a participant whose goal is
                  unattainable due to unforeseen circumstances outside of the
                  participant's control. Requests for adjustments must be made
                  in writing to the Senior Vice President of Sales within five

                              SALES INCENTIVE PLAN

SALES AND MARKETING MANAGEMENT

I.    OBJECTIVES:

      A.    To encourage participants who significantly contribute to Vicor's
            sales growth to support Vicor's sales goals within established
            expense standards.

II.   PRINCIPAL PROVISION:

      A.    Term

            The term of this plan is usually from January 1 through December 31,
            of each year.

      B.    Modification

            This plan may be modified by the President, as business situations,
            events and circumstances warrant.

      C.    Eligibility

            At the discretion of the President. Generally, managers who have
            participants in the Sales Incentive Plan reporting to them.

III.  INCENTIVE:

  Incentive will be based on the formula outlined below:

   Mgr./VP (incentive) = Mgr./VP (salary)                   x SIGMA RM incentive
                         ------------------------------------
                         SIGMA RM (salary) + Mgr./VP (salary)

      The incentive for the manager will be his/her salary divided by the sum of
the salaries of those sales persons reporting to said manager plus his/her
salary times the sum of all the aforesaid sales managers' incentive
compensation.

            An example based on the foregoing could be:

            Incentive =   $80,000                x $60,000
                          -----------------------
                          (5 x $60,000) + $80,000

            Incentive = $12,632

      This assumes an $80K salary, five sales persons making $60K and an
      incentive of $60K paid to the five sales managers.

IV.   MAXIMUM PAYMENT:

   A.    In no case will a Quarterly payment exceed 100% of a participant's
         base quarterly salary.
