in the strategic planning and implementation of the Company's current and future
strategies; and

WHEREAS, the Company desires to employ the Executive, and the Executive desires
to be employed by the Company on the terms and subject to the considerations set

NOW, THEREFORE, in consideration of the mutual promises herein contained, the
parties agree as follows:

     Chief Executive Officer ("CEO") or to the Company's Board of Directors (the
     "Board"). The Executive shall be required to devote his full business time,
     attention and effort to the Company's business and affairs and perform
     diligently such duties as are customarily performed by executives in
     similar positions with companies similar in character or size to the
     Company, all subject to the direction of the CEO or the Board, together
     with such other duties as may be reasonably requested from time to time by
     the CEO or the Board, which duties shall be consistent with his positions
     as set forth above. The Executive agrees to use all of his skills and
     business judgment and render services to the best of his ability to serve
     the interests of the Company. Subject to the terms of Section 9, nothing in
     this Agreement shall preclude Executive from serving on community and civic
     boards, participating in industry associations, or otherwise engaging in
     other non-commercial activities which do not unreasonably interfere with
     his duties to the Company. Notwithstanding the preceding sentence, the
     Company acknowledges and agrees that the Executive shall be entitled to
     continue participating in any current or future business ventures with his
     spouse so long as such business ventures do not unreasonably interfere or
     conflict with his duties to the Company.

(c)  Support Services.  The Executive shall be entitled to all of the
     -----------------

     situated executive.  This support shall include, without limitation, a
     suitably appointed private office, access to a secretary or administrative
     assistant, direct access to a Bloomberg Financial Markets terminal, and
     payment of or reimbursement for reasonable cellular telephone expenses,
     expenses of the Executive maintaining his professional license and standing
     and any and all other business expenses reasonably incurred on behalf of or
     in the course of performing duties for the Company, all documented in
     accordance with the expense reimbursement policies established from time to
     time by the Company and in effect for other similarly situated executives.
     The Executive agrees to provide such documentation of these expenses as may
     be reasonably required.

          automatically be extended for an additional year unless, not later
          than ninety (90) days prior to any such anniversary, the Company or
          the Executive shall have given notice not to extend the Term. For

          level appropriate to his positions with the Company, in any stock
          option plan or stock-based compensation plan which the Company
          maintains from time to time.  The Company agrees that it will take
          such actions as are

                                      -2-

 
          necessary (including, without limitation, amendment of the Employees

          Incentive Stock Option Plan, and/or the 1996 Stock

Option Plan (such existing plans as hereinafter referred to as the "Existing
Stock Option Plans") or create a new stock option plan as may be necessary) to
assure the following:

          (i)   The Executive is awarded effective as of the date of this
          Agreement qualified incentive stock options to purchase 300,000 common
          shares of the Company (the "Options"). Such Options shall have a ten
          year term and the strike price shall be equal to 100% of the closing
          per share price of the Company's common stock at the close of the
          trading day on the date of this Agreement. The Company acknowledges
          and agrees that it will waive any provisions in any existing or newly
          created incentive stock option plans that the Executive be an employee
          of the Company for a minimum of six months prior to granting such
          Options. The Options shall vest in equal 25% increments according to
          the following schedule:



                        Option Shares Represented     Vesting Date
                       -------------------------     -------------
                                                  
                       75,000                        April 1, 1998
                       75,000                        March 31, 1999
                       75,000                        March 31, 2000
                       75,000                        March 31, 2001


          The Company acknowledges that the award of the Options to purchase the
          above 300,000 common shares is based upon the premise that: (a) the
          Company has issued and outstanding approximately ten (10) million
          common shares as of the date hereof; (b) total common shares
          purchasable with respect to options available under the Company's
          Existing Stock Option Plans do not exceed three (3) million common
          shares as of the date hereof; and (c) there are no other equity or
          equity-linked securities (including, without limitation, convertible
          notes, convertible preferred stock, warrants, options, or any other
          type of security that consists of any type of right to purchase common
          shares; such equity or equity-link securities hereinafter referred to
          as "Equity Securities") outstanding as of the date hereof.
          
          (ii)  To the extent a change of control provision is not already
          provided for in any existing or newly created incentive stock option
          plans in a manner which is satisfactory to the Executive and
          consistent with the terms of this Agreement, the Company shall modify
          such existing or newly created stock option plans such that all
          Options or Future Stock Benefits (as defined in Section 8(b) hereof)
          held by the Executive shall become fully vested and exercisable and
          all restrictions upon any restricted shares held by the Executive will
          lapse immediately prior to a Change of Control as defined in Section 4
          of this Agreement.
                
          (iii) That the Company's Existing Stock Option Plans or future stock
          option plans contain certain antidilution provisions that stipulate
          that any event which effects the common shares of the Company in such
          a way that an adjustment of the Options or Future Stock Benefits is
          appropriate in order to prevent dilution of the rights of the
          Executive under the Options or Future Stock Benefits (including,
          without limitation, any dividend or other distribution (whether in
          cash or in kind), recapitalization, stock split, reverse split,
          reorganization, merger, consolidation, spin-off, combination,
          repurchase, or share exchange, or other similar corporate transaction
          or event), the Company shall make appropriate equitable adjustments,
          which may include, without limitation, adjustments to any or all of
          the number and kind of common shares of stock of the Company (or other
          securities) which may thereafter be issued upon exercise of the then
          outstanding Options or Future Stock Benefits and adjustments to the
          exercise price of all such Options and Future Stock Benefits. To the
          extent the Company's Existing Stock Option Plans do not contain such
          antidilution provisions or a reasonable proxy thereto, the Company
          shall work with the Executive to find a mutually agreeable solution.

                                      -3-

 
          (iv) Each grant of Options or Future Stock Benefits shall be evidenced
          by a separate Option Grant Agreement which shall be satisfactory to
          the Executive and executed within thirty (30) days of (a) the
          Effective Date of this Agreement in the case of the Options or (b) the
          grant date in the case of Future Stock Benefits.

     (c)  Relocation Expense.  If the Executive decides to permanently relocate
          ------------------                                                   
          himself and his family to the Boston, MA area or such other area as
          mutually agreed upon with the Company (the "Permanent Relocation"),
          the Company shall reimburse the Executive for all reasonable
          relocation expenses, up to $30,000, incurred with respect to the
          relocation of the Executive and his family. Notwithstanding the above,
          the Company shall reimburse the Executive for all reasonable commuting
          expenses until a Permanent Relocation occurs. The Company shall also
          reimburse the Executive for all reasonable expenses which he may incur
          with respect to establishing and maintaining temporary living quarters
          in the Boston area, or such other area as mutually agreed upon, until
          a Permanent Relocation occurs. If any such relocation, commuting, or
          living quarters expenses are treated as taxable income to the
          Executive, the Company shall make an additional payment to the
          Executive which shall make him whole with respect to the imposition of
          any federal, state, or local income tax on such taxable income.

     (d)  Insurance.  Beginning on the Effective Date, the Company shall provide
          ---------

          dental insurance for the Executive, and as appropriate for, his spouse
          and eligible family members, as is in accordance with the Company's
          policy for seniors officers of the Company.  The Company acknowledges
          and agrees that it will waive any waiting period for new employees.

     (e)  Retirement and Other Benefit Plans.  The Executive shall be eligible
          ----------------------------------                                  
          to participate in all retirement and other benefit plans of the
          Company generally available from time to time to employees and for
          senior executives of the Company and for which the Executive qualifies
          under the terms thereof, without regard to his tenure at the Company.
          The Executive shall also be entitled to participate in any equity or
          other employee benefit plans and other fringe benefits that are
          generally available to executive officers or directors from time to
          time, as distinguished from general management, of the Company.  The
          Executive's participation in and benefits under any such plan shall be
          on the terms and subject to the conditions specified in the governing
          document of the particular plan.

          for "Cause" (as defined in this Section 5(c)).  Upon such a
          termination, the Executive shall become entitled to the payments
          provided in Section 8(d) hereof.  For purposes of this Agreement, the
          Company shall have "Cause" to terminate the Executive's employment
          hereunder upon:
 

                                      -5-

 
          (i)   the willful (or grossly negligent) and continued failure by the
          Executive to substantially perform his duties hereunder (other than
          any such failure resulting from the Executive's incapacity due to
          physical or mental illness or any such actual or anticipated failure
          after the Executive has delivered a "Notice of Termination for Good
          Reason" as defined in Section 6(a) hereof, or during a "Window Period"
          as defined in Section 6(b) hereof) after demand for substantial
          performance is delivered by the Company that specifically identifies
          the manner in which the Company believes the Executive has not
          substantially performed his duties; or
 
          (ii)  the active participation by the Executive in an act or series of
          acts of willful malfeasance or gross misconduct, recklessness or gross
          negligence which a reasonable person would expect to have a material
          adverse effect on the Company; or
 
          (iii) any breach by the Executive of any of the provisions of Section
          9 hereof; or
 
          (iv)  the Executive's being convicted of, or pleading guilty to, a
          felony.

          For purposes of this paragraph, no act, or failure to act, on the
          Executive's part shall be considered "willful" unless done or omitted
          to be done, by him not in good faith and without reasonable belief
          that his action or omission was in the best interest of the Company.
          Further, unless the Executive has been convicted of, or pleaded guilty
          to, a felony, the Executive shall not be deemed to have been
          terminated without (1) reasonable notice to the Executive setting
          forth the reasons for the Company's intention to terminate for Cause,
          (2) an opportunity for the Executive, together with his counsel, to be
          heard before the Board, and (3) delivery to the Executive of a Notice
          of Termination from the Board finding that, in the good faith opinion
          of a majority of the Board, the Executive was guilty of conduct set
          forth above in clauses (i), (ii), or (iii) of this Section 6(c), and
          specifying the particulars thereof in reasonable detail.

     (d)  Without Cause.  The Company may terminate the Executive's employment
          -------------                                                       
          hereunder without Cause at any time.  Upon such a termination, the
          Executive shall become entitled to the payments and benefits provided
          in section 8(e) hereof.

6.  TERMINATION BY THE EXECUTIVE:
    ---------------------------- 

     (a)  Termination for Good Reason.  The Executive may terminate his
          ----------------------------                                 
          employment hereunder at anytime for "Good Reason".  Upon such
          Termination For Good Reason, the Executive shall become entitled to
          the payments and benefits provided in Section 8(e) hereof.  For the
          purposes of this Agreement, the definition of "Good Reason" shall
          include:  (i) any significant diminution in Executive's title, duties
          and responsibilities or such title, duties and responsibilities are
          otherwise diminished such that they no longer reflect the title,
          duties and responsibilities customary for a Chief Financial Officer
          and/or Director of Corporate Development, which diminution is not
          cured within thirty (30) days after notice from the Executive, (ii)
          the Company (or any successor thereto) hires or appoints a person,
          other than Executive, to the position (or functional equivalent,
          regardless of actual title) of Chief Financial Officer and/or Director
          of Corporate Development, (iii) any failure of the Company to pay any
          compensation to the Executive within thirty (30) days of the
          Executive's notice to the Company that payment is overdue; and/or (iv)
          the Company's breach of a material term or condition of this
          Agreement, and the Company's failure to correct such breach within
          thirty (30) days after the Executive's notice thereof (specifying in
          reasonable detail the particulars of such noncompliance).

     (b)  Termination During a Window Period.  The Executive may terminate his
          ----------------------------------                                  
          employment hereunder without Good Reason by giving a Notice of
          Termination during a "Window Period", which for purposes of this
          Agreement, shall mean the sixty (60) day period beginning with the
          first day following the ninety (90) day period which immediately
          follows a Change of Control.  Upon a Window Period termination, the
          Executive shall become entitled to the payments and benefits provided
          in Section 8(e) hereof.

                                      -6-

 
     (c)  Termination Without Good Reason Outside a Window Period.  The
          -------------------------------------------------------      
          Executive may terminate his employment hereunder without Good Reason
          and outside of a Window Period, upon giving thirty (30) days written
          notice to the Company.  In the event of such a termination, the
          Executive shall comply with any reasonable request of the Company to
          assist in providing for an orderly transition of authority, but such
          assistance shall not delay the Executive's termination of employment
          longer than sixty (60) days beyond the giving of the Executive's
          Notice of Termination.  Upon such a termination, the Executive shall
          become entitled to the payments provided in Section 8(f) hereof.

     ------------------------------------------

     (a)  Notice of Termination.  Any purported termination of the Executive's

          the Date of Termination shall be extended by a notice of dispute given
          by the Executive only if such notice is given in good faith and the
          Executive pursues the resolution of such dispute with reasonable
          diligence.

     (d)  Compensation During Dispute.  Except in the event of Termination for
          ---------------------------                                         
          Cause by the Company, I if the Date of Termination is extended in

          with Section 7(c) hereof.  Amounts paid under this Section 7(d) are in
          addition to all other amounts due under this Agreement and shall not

          "Future Stock Benefits") shall vest immediately.

     (c)  Termination For Permanent Disability:  If the Executive's employment
          ------------------------------------                                
          is terminated by the Company for Permanent Disability, the Executive
          shall be entitled to receive any accrued but unpaid salary and other
          benefits up to and including the date of the Executive's termination.

     (e)  Termination Without Cause, Termination For Good Reason, and
          -----------------------------------------------------------
          Termination During a Window Period.  If the Executive's employment
          -----------------------------------                               
          hereunder is terminated (1) by the Company without Cause, (2) by the
          Executive for Good Reason, or (3) by the Executive during a Window
          Period, then:
 
          (i)    As soon as practicable after the Date of Termination, but no
          later than ten (10) days after such date, the Company shall pay to the
          Executive any amounts earned, accrued or owing the Executive under the
          terms hereunder for services to the Date of Termination.
 
          (ii)   As soon as practicable after the Date of Termination, but no
          later than ten (10) days after such date, the Company shall pay to the
          Executive a lump sum amount, in cash, equal to the sum of (A) any
          Annual Bonus which has been allocated or awarded to the Executive, but
          not yet paid, for a completed fiscal year preceding the Date of
          Termination under any Annual Bonus plan, and (B) a pro rata portion to
          the Date of Termination of the Annual Bonus for the year in which the
          Date of Termination occurs, assuming the Executive would have received
          an Annual Bonus equivalent to the highest previous Annual Bonus which
          the Executive received in any given year during the Employment Period.
          In the event such termination occurs in the first year of employment,
          the Executive's pro rata Annual Bonus will be based on a full year
          bonus of $75,000.
 
          (iii)  In lieu of any further salary or bonus payments to the
          Executive for periods subsequent to the Date of Termination, the
          Company shall pay as a severance payment to the Executive, within ten
          (10) days immediately following the Date of Termination, a lump sum
          amount, in cash, equal to the sum of: (A) two year's Base Salary at
          the Executive's highest annual Base Salary rate in effect during the
          Employment Period and (B) an amount equivalent to twice the highest
          Annual Bonus that the Executive received in any given year during the
          Employment Period or $150,000, whichever is higher.
 
          (iv)   The Company shall maintain in full force and effect, for the
          continued benefit of the Executive until the later of (x) the second
          anniversary of the Date of Termination or (y) the end of the Term,
          each "employee welfare benefit plan" (as defined in Section 3(1) of
          the Employee

                                      -8-

 
          Retirement Income Security Act of 1974, as amended ("ERISA")), other
          than any disability plan, in which the Executive was entitled to
          participate immediately prior to the Date of Termination, provided
          that the Executive's continued participation is possible under the
          general terms and provisions of such plans. In the event that the
          Executive's participation in any such plan is barred, the Company
          shall arrange to provide the Executive with benefits substantially
          similar to those which the Executive would otherwise have been
          entitled to receive under the plan from which his continued
          participation is barred;
 
          (v)  Any unvested Options or Future Stock Benefits shall, to the
          extent not already vested, vest immediately upon the Date of
          Termination;
 
          (vi) The Company shall have no additional obligations to the Executive
          under this Agreement except to the extent provided in Sections 3(e)
          and 3(f).

     (f)  Termination Without Cause Outside a Window Period by the Executive. If
          ------------------------------------------------------------------    
          the Executive's employment is terminated by the Executive without
          Cause outside of a Window Period, the Company shall not have any other
          or further obligations to the Executive under this Agreement except
          (i) as to that portion of any unpaid Base Salary and other benefits
          accrued and earned under this Agreement to the date of termination,
          and (ii) as may be provided in accordance with the terms of retirement
          and other benefit plans pursuant to Section 3(e) and 3(f).  In
          addition, the pro rata portion of any unvested Options or Future Stock
          Benefits that were scheduled to vest in the year of the Executive's
          termination shall vest immediately.  Such pro rata amount will be
          determined in each such case for the Options and Future Stock Benefits
          by taking the number of Options or Future Stock Benefits (whichever
          the case may be) which were scheduled to vest on the next succeeding
          vesting date after the Date of Termination and multiplying each by a
          fraction, the numerator of which is the number of days that have
          elapsed from the vesting date immediately preceding the Date of
          Termination (or the grant date) to the Date of Termination, and the
          denominator of which shall be the number of days scheduled between the
          most recent vesting date preceding the Date of Termination (or the
          grant date) and the vesting date first succeeding the Date of
          Termination (such formula hereinafter referred to as the "Pro Rata
          Option Formula").

     (g)  Mitigation.  The Executive shall not be required to mitigate amounts
          ----------                                                          
          payable pursuant to Section 8 hereof by seeking employment or
          otherwise, but any payments made or benefits provided pursuant to
          Section 8(e)(iv) hereof shall be offset by any similar payments or
          benefits made available without cost to the Executive from any
          subsequent employment during the Term (determined immediately prior to
          such termination of employment.)

9.   CONFIDENTIAL INFORMATION:
     ------------------------ 

     (a)  Unauthorized Disclosure.   The Executive shall not, either during the
          -----------------------                                              
          Executive's employment hereunder or thereafter, disclose, divulge,
          discuss, copy or otherwise use or suffer to be used in any manner,
          other than in accordance with the Executive's duties hereunder, any
          confidential or proprietary information relating to the Company's
          business, prospects, finances, operations, customers, products,
          services, rates, properties or otherwise to its particular business or
          other trade secrets of the Company, it being acknowledged by the
          Executive that all such information regarding the business of the
          Company compiled or obtained by, or furnished to, the Executive while
          the Executive shall have been employed by or associated with the
          Company is confidential and/or proprietary information and the
          Company's exclusive property; provided, however, that the foregoing
          restrictions shall not apply to the extent that such information:

          (i)  is clearly obtainable in the public domain; or

          (ii) becomes obtainable in the public domain, except by reason of the
               breach by the Executive of the terms hereof; or

                                      -9-

 
          (iii)  is required to be disclosed by rule of law or by order of a
                 court or governmental body or agency.

     (b)  The Executive agrees and understands that the remedy at law for any
          breach by him of this Section 9 will be inadequate and that the
          damages flowing from such breach are not readily susceptible to being
          measured in monetary terms.  Accordingly, it is acknowledged that the
          Company shall be entitled to seek immediate injunctive relief.
          Nothing in this Section 9 shall be deemed to limit the Company's
          remedies at law or in equity for any breach by the Executive of any of
          the provisions of this Section 9 which may be pursued or availed of by
          the Company.

     (c)  The Executive acknowledges that the Executive's obligations under this
          Section 9 shall survive regardless of whether the Executive's
          employment by the Company is terminated, voluntarily or involuntarily,
          by the Company or the Executive, with Cause or without Cause.

10.  EXCISE TAX GROSS-UP PAYMENT:
     --------------------------- 

     (a)  Notwithstanding anything herein to the contrary, if it is determined
          that any payment and/or other compensation under the terms of this
          Agreement or otherwise would be subject to the excise tax imposed by
          Section 4999 and/or Section 280 of the Internal Revenue Code (the
          "Code") or any interest or penalties should be assessed with respect
          to such excise tax (such excise tax, together with any interest or
          penalties thereon, is herein referred to as an "Excise Tax"), then
          Executive shall be entitled to an additional cash payment (a "Gross-Up
          Payment") in an amount that will place Executive in the same after-tax
          economic position that Executive would have enjoyed if the Excise Tax
          had not applied to such payment and/or other compensation.  The amount
          of the Gross-Up Payment shall be determined by an accounting firm
          selected by the Executive in his sole discretion (the "Accounting
          Firm") in accordance with such formula as the Accounting Firm deems
          appropriate.  No Gross-Up Payments shall be payable hereunder if the
          Accounting Firm determines that the payments and/or other compensation
          are not subject to an Excise Tax.  The Accounting Firm shall be paid
          by the Company (or any successor thereto) for services performed
          hereunder.

     (b)  All determinations required under this Section 10, including whether a
          Gross-Up Payment is required, the amount of the payment and/or other
          compensation constituting excess parachute payments, and the amount of
          the Gross-Up Payment, shall be made by the Accounting Firm, which
          shall provide detailed supporting calculations to both Executive and
          the Company within fifteen (15) days of any date reasonably requested
          by the Executive on which a determination under this Section 10 is
          necessary or advisable. The Company shall pay to the Executive, in
          cash, subject to any applicable tax withholding requirements, the
          Gross-Up Payment within fifteen (15) days of the receipt of the
          Accounting Firm's determination. If the Accounting Firm determines
          that no Excise Tax is payable by Executive, the Company agrees that
          the Accounting Firm shall provide the Executive with an opinion that
          the Accounting Firm, having substantial authority under the Code and
          other tax regulations and based on its judgement and an assessment of
          the facts, does not believe the Executive will have to report an
          Excise Tax on the Executive's federal income tax return. Any
          determination by the Accounting Firm shall be binding upon the
          Executive and the Company (or any successor thereto).

     (c)  In the event that it is finally determined by the Internal Revenue
          Service on audit or in a judicial proceeding that the Executive is
          liable for any Excise Tax in an amount other than that determined by
          the Accounting Firm, the Gross-Up Payment shall be recomputed by the
          Accounting Firm based on the Excise Tax that is finally determined to
          be due.  The Executive shall refund any resulting overpayment
          (together with interest at the prevailing short-term applicable
          federal rate under section 1274 of the Code) and the payer of the
          original Gross-Up Payment shall pay to the Executive any resulting
          shortfall (together with interest at the short-term applicable federal
          rate under section 1274 of the Code), promptly following such
          recomputation.  The Company shall indemnify the Executive against any
          costs and expenses (including the reasonable fees of

                                      -10-

 
          attorneys and accountants) incurred in connection with any audit or
          examination of, or legal proceedings in connection with, his tax
          return for any taxable year for which an Excise Tax is, or is alleged
          to be, due, to the extent attributable to the issue of such Excise
          Tax.

MISCELLANEOUS:
- ------------- 

     (a)  The Executive represents and warrants that he is not a party to any
          agreement, contract or understanding, whether employment or otherwise,
          which would restrict or prohibit him from undertaking or performing
          employment in accordance with the terms and conditions of this
          Agreement.

     (b)  The provisions of this Agreement are severable and if any one or more
          provisions may be determined to be illegal or otherwise unenforceable,
          in whole or in part, the remaining provisions and any partially
          unenforceable provision to the extent enforceable in any jurisdiction
          nevertheless shall be binding and enforceable.

     (c)  At all times during and after Executive's employment and the date of
          this Agreement, the Company shall indemnify the Executive to the
          fullest extent permitted by law for all expenses, costs, liabilities
          and legal fees which the Executive may incur in the discharge of his
          duties hereunder and shall at all times maintain appropriate
          provisions in its articles of incorporation and bylaws which mandate
          that the Company provide such indemnification.  The Company shall also
          provide, for the benefit of the Executive, Directors and Officers'
          liability insurance in amounts which are customary for directors and
          officers of other public companies similar in character or size to the
          Company.  Any termination of the Executive's employment or of this
          Agreement shall have no effect on the continuing operation of this
          Section 11(c).

     (d)  The Company shall reimburse Executive for reasonable fees and expenses
          incurred in connection with the negotiation and execution of this
          Agreement, including, without limitation, the reasonable fees and
          expenses of his attorneys.

     (e)  The Company will require any purchaser of all or substantially all of
          the business and/or assets of the Company, by agreement in form and
          substance satisfactory to the Executive, to expressly assume and agree
          to perform this Agreement in the same manner and to the same extent
          that the Company would be required to perform it if no such succession
          had taken place.  As used in this Agreement, "Company" shall mean the
          Company as herein before defined and any successor to its business
          and/or assets as aforesaid which executes and delivers the agreement
          provided for in this Section 11(e) or which otherwise becomes bound by
          all the terms and provisions of this Agreement by operation of law.

     (f)  This Agreement and all rights of the Executive hereunder shall inure
          to the benefit of and be enforceable by the Executive's personal or
          legal representatives, executors, administrators, successors, heirs,
          distributees, devisees, and legatees. If the Executive should die
          while any amounts would still be payable to him hereunder if he had
          continued to live, all such amounts unless otherwise provided herein,
          shall be paid in accordance with terms of this Agreement to the
          Executive's devisee, legatee, or other designee or, if there be no
          such designee, to the Executive's estate.

     (g)  Any controversy or claim arising out of or relating to this Agreement,
          or the breach thereof, shall be settled by arbitration in accordance
          with the Commercial Arbitration Rules of the American Arbitration
          Association then pertaining in the metropolitan Boston, MA area, and
          judgment upon the award rendered by the arbitrator or arbitrators may
          be entered in any court having jurisdiction thereof.  The arbitrator
          or arbitrators shall be deemed to possess the powers to issue
          mandatory orders and restraining orders in connection with such
          arbitration.  The Company (or any successor thereto) and the Executive
          each agree to use their best efforts to begin the arbitration process

                                      -11-

 
          within three months of any notification from the other party
          requesting arbitration to settle a dispute.  The Company (or any
          successor thereto) shall pay all costs of any such proceeding.

     (h)  All notices and other communications required or permitted under this
          Agreement shall be in writing, and shall be deemed properly given if
          delivered personally, mailed by registered or certified mail in the
          United States mail, postage prepaid, return receipt requested, sent by
          facsimile, or sent by Express Mail, Federal Express or nationally
          recognized express delivery service, as follows:

          Notice given by hand, certified or registered mail, or by Express
          Mail, Federal Express or other such express delivery service, shall be
          effective upon actual receipt.  Notice given by facsimile transmission
          shall be effective upon telephonic confirmation of receipt by the
          party to whom it is addressed.  All notices by facsimile transmission
          shall be followed up promptly after transmission by delivering an
          original copy by hand, certified or registered mail, or by Express
          Mail, Federal Express or other such delivery service.  Any party may
          change any address to which notice is to be given to it by giving
          notice as provided above of such change of address.

     (i)  The failure of either party to enforce any provision or provisions of
          this Agreement shall not in any way be construed as a waiver of any
          such provision or provisions as to any future violations thereof, nor
          prevent that party thereafter from enforcing each and every other
          provision of this Agreement.  The rights granted the parties herein
          are cumulative and the waiver of any single remedy shall constitute a
          waiver of such party's right to assert all other legal remedies
          available to it under the circumstances.

     (j)  This Agreement supersedes all prior agreements and understandings
          between the parties and may not be modified or terminated orally.  No
          modification or attempted waiver shall be valid unless in writing and
          signed by the party against whom the same is sought to be enforced.

                                      -12-

 
     (k)  This Agreement shall be governed by, and construed in accordance with
          the provisions of, the law of the Commonwealth of Massachusetts,
          without reference to provisions that refer a matter to the law of any
          other jurisdiction.  Each party hereto hereby irrevocably submits
          itself to the non-exclusive personal jurisdiction of the federal and
          state courts sitting in Massachusetts; accordingly, subject to the
          provisions for arbitration provided in Section 11(g), any justiciable
          matters involving the Company and the Executive with respect to this
          Agreement may be adjudicated only in a federal or state court sitting
          in Massachusetts.

     (l)  All payments required to be made by the Company hereunder to the
          Executive shall be subject to the withholding of such amounts relating
          to taxes and other government assessments as the Company may
          reasonably determine it should withhold pursuant to any applicable
          law, rule or regulation.

     (m)  Captions and section headings used herein are for convenience and are
          not a part of this Agreement and shall not be used in construing it.

     (n)  Where necessary or appropriate to the meaning hereof, the singular and
          plural shall be deemed to include each other, and the masculine,
          feminine and neuter shall be deemed to include each other.

     (o)  This Agreement may be executed in any number of counterparts and by
          different parties hereto in separate counterparts, each of which when
          so executed shall be deemed to be an original and all of which taken
          together shall constitute one and the same agreement.  Delivery of an
          executed counterpart of this Agreement by telecopier shall be
          effective as delivery of a manually executed counterpart of this
          Agreement.

                                      -13-
