          a. BASE SALARY. The Company shall pay Employee a base salary at an
     annual rate (the "Base Salary") equal to $140,000 per year, payable in
     accordance with the payroll practices of the Company for its executives,
     subject to annual salary reviews by the Compensation Committee of the
     Company's Board of Directors (the "Compensation Committee") or the
     President, as appropriate, on October 1st of each year for the duration of

                       Goals Achieved*                      Earned as Bonus
                  ------------------------             ------------------------

          *    For percentages between 80% and 120%, the percentage of Base
               Salary that may be earned by Employee will be determined by
               linear interpolation.

          c. On the Effective Date of this Agreement, Employee will be awarded
     an incentive stock option to purchase 30,000 shares of Common Stock (the

     September 23, 2000                  25%                       100%

                    holding securities under an employee benefit plan of the
                    Company, or any corporation owned, directly or indirectly,
                    by the stockholders of the Company in substantially the same

                    representing 15% or more of the combined voting power of

                    cease for any reason, including without limitation as a
                    result of a tender offer, proxy contest, merger or similar
                    transaction, to constitute at least a majority of the Board
                    of Directors, provided that any person becoming a director
                    of the Company subsequent to the Effective Date whose
                    election was approved by at least a majority of the
                    directors then comprising the Incumbent Board shall, for
                    purposes of this Agreement, be considered a member of the

                         (iii) the stockholders of the Company approve a merger
                    or consolidation of the Company with any other corporation
                    or other entity, other than (a) a merger or consolidation
                    which would result in the voting securities of the Company
                    outstanding immediately prior thereto continuing to
                    represent (either by remaining outstanding or by being
                    converted into voting securities of the surviving entity)
                    more than 50% of the combined voting power of the voting
                    securities of the Company or such surviving entity
                    outstanding immediately after such merger or consolidation
                    or (b) a merger or consolidation effected to implement a
                    recapitalization of the Company (or similar transaction) in
                    which no "person" (as hereinabove defined) acquires more
                    than 50% of the combined voting power of the Company's then
                    outstanding securities; or

                         (iv) the stockholders of the Company approve a plan of
                    complete liquidation of the Company or an agreement for the
                    sale or disposition by the Company of all or substantially
                    all of the Company's assets.



                    (3) A "Terminating Event" shall mean any voluntary or
               involuntary termination of Employee's employment occurring
               subsequent to a Change of Control, other than the termination of
               Employee's employment pursuant to Section 5d hereunder.

               c. DEATH OR DISABILITY. In the event Employee dies or becomes
          disabled during the Term this Agreement, his employment hereunder
          shall automatically terminate. In such case, the Company shall pay to
          Employee or his beneficiary, as the case may be, any earned but unpaid


                                       4
   5



          salary as of the date of his death or disability. For the purpose of
          this Agreement, "disability" shall refer to a situation in which
          Employee is totally disabled from performing his duties for the
          Company during a period of thirteen (13) consecutive weeks.

               If any question shall arise as to whether during any period
          Employee has suffered disability, Employee may, and at the request of
          the Company will, submit to the Company a certification in reasonable
          detail by a physician selected by Employee or his guardian to whom the
          Company has no reasonable objection as to whether Employee was so
          disabled and such certification shall for the purposes of this
          Agreement be conclusive of the issue. If such question shall arise and
          Employee shall fail to submit such certification, the Company's
          determination of such issue shall be binding on Employee.

               d. BY THE COMPANY FOR CAUSE. The Company may terminate Employee's
          employment hereunder for cause at any time upon notice to Employee
          setting forth in reasonable detail the nature of such cause. The
          following, as determined by the Board of Directors in its reasonable
          judgment, shall constitute "cause" for termination:

                    (1) Employee's falsification of the accounts of the Company,
               embezzlement of funds of the Company or other material dishonesty
               with respect to the Company or any of its affiliates; or

                    (2) Conviction of, or plea of nolo contendere to, a felony
               or other crime involving moral turpitude (it being understood
               that violation of a motor vehicle code does not constitute such a
               crime); or

                    (3) Conduct engaged in or action taken or omitted to be
               taken by Employee which is in material breach of this Agreement;
               or

                    (4) Material failure to perform a substantial portion of
               Employee's duties and responsibilities hereunder, which failure
               continues for more than thirty (30) days after written notice
               given to Employee pursuant to a vote of the Board of Directors,
               such vote to set forth in reasonable detail the nature of such
               failure; or

                    (5) Gross or willful misconduct of Employee' with respect to
               the Company or any subsidiary or affiliate thereof.

          Upon the giving of notice of termination of Employee's employment
     hereunder for cause, the Company shall have no further obligation or
     liability to Employee, other than the payment of salary earned and unpaid
     at the date of termination and the contribution by the Company to the cost
     of Employee's participation (subject to any required employee contribution
     by Employee under the terms of the applicable plans) in the Company's group
     medical and dental insurance plans as the same are in effect from time to
     time for so long as Employee is entitled to continue such participation
     under applicable law and plan terms.

          e. LIMITATION OF BENEFITS. It is the intention of Employee and of the
     Company that no payments by the Company to or for the benefit of Employee
     under this Agreement or any ether agreement or plan pursuant to which he is
     entitled to receive payments or benefits shall be non-deductible to the
     Company by reason of the operation of Section 280G of the Internal Revenue
     Code of 1986, as amended (the "Code") relating to "parachute payments,"
     Accordingly, and notwithstanding any other provision of this Agreement or
     any such agreement or plan, if by reason of the operation of said Section
     280G, any such payments exceed the amount which can be deducted by the
     Company, the payments which Employee is entitled to receive under this
     Agreement shall be reduced by that amount which exceeds the maximum amount
     deductible by the Company under Section 280G. To the extent that payments
     exceeding such maximum deductible amount have been made to or for the
     benefit of Employee, such excess payments shall be refunded to the Company
     with interest thereon at the applicable federal rate determined under
     Section 1274(d) of the Code, compounded annually, or at such other rate as
     may be required in order that no such payments shall be non-deductible to
     the Company by reason of the operation of said Section 280G.

     6. WITHHOLDING. All payments made by the Company under this Agreement shall
be reduced by any tax or other amounts required to be withheld by the Company
under applicable law.

this Agreement or any interest herein, by operation of law or otherwise,
without the prior written consent of the other; provided, however, that the
Company may assign its rights and obligations under this Agreement without the
consent of Employee in the event that the Company shall hereafter affect a
reorganization, consolidate with, or merge into, any other person or entity or
transfer all of its properties or assets to any other person or entity. This
Agreement shall inure to the benefit of and be binding upon the Company and
Employee, their respective successors, executors, administrators, heirs and
permitted assigns.

     8. SEVERABILITY. If any portion or provision of this Agreement shall to any
extent be declared illegal or unenforceable by a court of competent
jurisdiction, then the remainder of this Agreement, or the application of such
portion or provision in circumstances other than those as to which it is so
declared illegal or unenforceable, shall not be affected thereby, and each
portion and provision of this Agreement shall be valid and enforceable to the
fullest extent permitted by law.

     9. WAIVER. No waiver of any provision hereof shall be effective unless made
in writing and signed by the waiving party. The failure of either party to
require the performance of any term or obligation of this Agreement, or the
waiver by either party of any breach of this Agreement, shall not prevent any
subsequent enforcement of such term or obligation or be deemed a waiver of any
subsequent breach.

     10. NOTICES. Any and all notices, requests, demands and other
communications provided for by this Agreement shall be in writing and shall be
deemed given when delivered by hand, telex or facsimile, or if mailed, five days

attention of Clerk or to such other address as either party may specify by
notice to the other.

Agreement executed by Employee constitute the entire agreement between the
parties and supersedes all prior communications, agreements and understandings,
written or oral, with respect to the terms and conditions of Employee's
employment.

     12. AMENDMENT. This Agreement may be amended or modified only by a written
instrument signed by Employee and by an expressly authorized representative of
the Company.

     13. HEADINGS. The headings and captions in this Agreement are for
convenience only and in no way define or describe the scope of or content of any
provision of this Agreement.

     14. COUNTERPARTS. This Agreement may be executed in two or more
counterparts, each of which shall be an original and all of which together shall
constitute one and the same instrument.

     15. GOVERNING LAW. This is a Massachusetts contract and shall be construed
and enforced under and be governed in all respects by the laws of The
Commonwealth of Massachusetts, without regard to the conflict of laws principles
thereof.
