     (d)  For and with respect to the individual Seaport Products or their
     successor products which are at a later date incorporated (whether embedded
     or as an add-on product) into any other product(s) of Employer or its
     affiliates (such product into which any or all of such individual Seaport
     Products are incorporated is hereinafter referred to as a "Xionics
     Product"), Xionics shall pay the employee Additional Salary calculated in
     the following manner:

          (i)   SeaWorthy Products- Employer shall pay to employee 20% of the
                calculated revenue (as hereinafter described), if any, for the
                first three (3) years of the term of this Agreement, and 10% of
                the calculated revenue, if any, for the next two (2) years of
                this Agreement.

          (ii)  SeaBars Products - Employer shall pay to employee 20% of the
                calculated revenue (as hereinafter described), if any, for the
                first three (3) years of the term of this Agreement, and 10% of
                the calculated revenue, if any, for the next two (2) years of
                this Agreement.

          (iii) Cruise Line Products- Employer shall pay to employee 10% of the
                Cruise Line calculated revenue (hereinafter described), if any,
                for the first (3) years of the term of this agreement.

     (e) (i) "Calculated revenue" shall mean the result of (a) the actual
     sale price of the Xionics Product multiplied by (b) the amount which is the
     result of dividing (1) the list price of the individual Seaport Product by
     (2) the total of list prices of all components of the Xionics Product.


                                       3

     As an example:

<TABLE>
     <S>                                              <C>
     (List Price of individual Seaport
     Products included in Xionics Product)      X     (the actual sale price  = calculated revenue
     ----------------------------------------         of the Xionics Product)
     (Total of List Prices of all components          
      in the Xionics Product)
</TABLE>

          (ii) If the Xionics Product is an embedded product, the pricing for
     the embedded product will include line item pricing, and such line item
     prices will be maintained on a published price list for the period of time
     during which the Additional Salary payments are due.

     (iii) Cruise Line calculated revenue shall mean the result of (a) the
     actual sale price for the Cruise Line Product, less amounts due by Seaport
     or Employer to Optimis Systems, Inc. pursuant to the Optimis Agreement, for
     such product, multiplied by (b) the amount which is the result of dividing
     (1) the list price of the Cruise Line Product included in the Xionics
     Product by (2) the total of list prices of all components of the Xionics
     Product.

     (f)   In the event the total actual sales for all products which comprised
     products of the company Seaport Imaging prior to the Closing Date
     ("Seaport's traditional products"), other than the Seaport Products, during
     the first six (6) months after the date of execution of the Stock Purchase
     Agreement ("Total Sales") is less than $1,100,000.00, then two times the
     difference between the Total Sales and $900,000.00 shall be deemed to be
     "Earned Credit". The difference between the Earned Credit, if any, and
     $400,000.00 shall be the "Offset Amount". After calculation of the Offset
     Amount, the Offset Amount, if any, will be deducted from future monthly
     payments of Additional Salary otherwise due to Employee as described in
     4.4(b) above until the Offset Amount has been completely exhausted. (As an
     example only, if Total Sales equals $1,050,000.00 for the period, the
     Earned Credit would be $300,000.00, and the amount deducted from future
     monthly payments of Additional Salary would be $100,000.00).
     Notwithstanding the foregoing, in no event shall the Offset Amount exceed
     $400,000.00.

     (g)   Except as set forth below, the Additional Salary payments described 
     in Section 4.4(b) shall continue for the full period anticipated under
     Section 4.4(b) regardless of whether or not this Agreement is sooner
     terminated for any reason whatsoever or expires or whether Employee is
     employed by the Employer as anticipated by this Agreement at the time such
     payment is due to Employee. In the event of employees death or disability
     during the period when Additional Salary payments would otherwise be due,
     employer shall continue to pay the Additional Salary to the Employee or his
     estate or heirs, as the case may be. Notwithstanding the foregoing, in the
     event that employee resigns his position with Employer prior to the
     expiration of the Initial Term, then the Additional Salary payments will
     continue, but will be reduced as follows: the total Additional Salary,
     after calculation, will be reduced by 10% for the period of months
     remaining in the Initial Term (in other words, Additional Salary payments
     will be calculated at 18% of the applicable revenue rather than 20% for the
     remainder of the Initial Term with respect to SeaWorthy Products and
     SeaBars Products, and 9% of the applicable revenue rather than 10% with
     respect to Cruise Line Products).


                                       4

     (h)  Employer will keep and maintain, for a period of two years, proper
     records and books of account relating to Employers marketing and
     distribution of products for which Additional Salary is payable here under.
     Employer will have conducted, as a part of the independent review of its
     corporate books, quarterly during the first year of this Agreement and
     thereafter on an annual basis (or quarterly if so requested by Employee),
     an independent review of the Additional Salary calculations payable and
     paid to Employee under this Agreement. Upon completion of the independent
     review, the auditor performing the review will provide to Employee a
     certification of the accuracy of the Additional Salary payments made during
     the period covered by the review. If the payments made were less than that
     which was due, the balance due will be paid with the next monthly
     Additional Salary payment. If the payments were in excess of what should
     have been paid, the over payment will be deducted from the next months
     Additional Salary payment. The cost to perform this independent review will
     be born by the Employer and will continue for the period the Additional
     Salary payments are due pursuant to the terms of this Agreement.

5.   RELOCATION. The Employee is currently resident in California. In the event
     Employee's permanent presence in Employer's Burlington, MA office is
     desired by Xionics, Employee may at his discretion relocate to
     Massachusetts at the earliest feasible date following such request. The
     Employer agrees to pay the mutually agreed upon, reasonable, customary and
     ordinary expenses of such relocation.

6.   INVENTION DISCLOSURE AND CONFIDENTIALITY. The Employee understands that his
     position with the Employer is one of high trust and confidence, by reason
     of his access to and contact with the trade secrets and confidential and
     proprietary information of the Employer. Therefore, the Employee agrees
     that he will execute the Employer's standard Employee Invention and
     Non-Disclosure Agreement, in the form attached hereto as Exhibit B; and
     that upon its execution such Employee Invention and Non-Disclosure
     Agreement will be incorporated in and made a part of this Agreement.

7.   TERMINATION. Notwithstanding Section 3. above, the Employee's employment
     shall terminate:

7.1  DEATH OR DISABILITY. Upon the death of the Employee during the term of his
     employment hereunder or, at the option of the Employer, upon thirty (30)
     days' prior written notice from the Employer in the event of the Employee's
     disability. The Employee shall be deemed disabled if an independent medical
     doctor (selected by the Employer's health or disability insurance carrier)
     certifies that the Employee has, for ninety (90) days, consecutive or
     non-consecutive, in any twelve (12)-month period been materially impaired
     in his ability to perform his duties under this Agreement.

7.2  FOR CAUSE. For Cause, as defined below, immediately upon written notice
     given to the Employee by the Employer. For purposes of this Agreement,
     "Cause" shall mean any one or more of the following:

     (a)  An act of fraud, embezzlement, misappropriation or breach of fiduciary
     duty committed by the Employee against the Employer, including but not
     limited to the offer, payment, solicitation or acceptance of any unlawful
     bribe or kickback with respect to the Employer's business;

     (b)  The Employee's conviction by a court of competent jurisdiction of any
     felony;



                                       5

<PAGE>   6


     (c)  The Employee's breach of any of the covenants, terms or provisions of
     the Employee Invention and Non-Disclosure Agreement to be executed pursuant
     to Section 6. above;

     (d)  The Employee's substantial failure to perform (whether because of
     inability, unwillingness, negligence, or any other reason based upon the
     act or failure to act of Employee) the duties and responsibilities
     reasonably assigned to him by the Employer in a manner reasonably
     satisfactory to the Employer, which failure continues for sixty (60) days
     after notice of such failure from an Authorized Officer; or

     (e)  The Employee's refusal to obey any lawful direction by an Authorized
     Officer which is consistent with his duties and responsibilities hereunder,
     which refusal continues for five (5) days after written notice to the
     Employee specifying such refusal in reasonable detail.

7.3  RIGHTS AND REMEDIES ON TERMINATION. If the Employer shall terminate the
     Employee's employment hereunder other than as provided in Sections 7.1 and
     7.2 above, then the Employee shall be entitled to receive, as severance pay
     and in consideration of his ongoing obligations under the Employee
     Invention and Non-Disclosure Agreement referred to above, in accordance
     with the Employer's then-current payroll practices, payment of his Base
     Salary in effect at the time of termination for the shorter of one (1) year
     or the remainder of the Initial Term (the "termination payment period");
     provided, however, that in the event of any such termination, half way
     through the termination payment period, the parties shall determine
     Employee's employment status, and if at such time Employee has secured
     other employment, then no additional payments for the balance of the
     termination payment period shall be due from Employer to Employee.


7.4  EFFECT OF NO CLOSING. Notwithstanding any of the other provisions of this
     Agreement, in the event the Closing Date does not occur on or before
     September 10, 1997, this Agreement shall become null and void, as if the
     same had never been entered into between the parties, and no obligations of
     either party hereto shall be enforceable against the other, and no amounts
     otherwise due from Employer to Employee under any section of this Agreement
     shall be due or payable.

8.   GENERAL.

8.1  NO RIGHTS IN SOFTWARE/HARDWARE. Except for that certain patent number
     5,557,091 (which employee will assign to Employer pursuant to the terms of
     the Stock Purchase Agreement between Employer and Employee, as one of the

     sale or transfer of all or substantially all of the assets and business of,
