payable to the Executive under this Agreement shall be as follows:

            (a) Salary. For all services rendered by the Executive under this
      Agreement, the Bank or the Company shall pay the Executive a salary at the
      rate of $380,000 per year, subject to increase from time to time in
      accordance with the usual practice of the Bank and the Company with
      respect to review of compensation of their senior


      executives, provided, however, that the Executive's salary shall be
      increased annually by a percentage amount equal to at least the percentage
      increase during the immediately preceding twelve months in the Consumer
      Price Index (All Items) for all Urban Consumers for the Boston,
      Massachusetts area, as published by the Bureau of Labor Statistics, or if
      such Index is not available, the U.S. Government Index which is the most
      similar thereto. The Executive's salary shall be payable in periodic
      installments in accordance with the Bank's and the Company's usual
      practice for its senior executives.

            (b) Regular Benefits. The Executive shall also be entitled to
      participate in any and all employee benefit plans, medical insurance
      plans, life insurance plans, disability income plans, retirement plans,
      bonus incentive plans and other benefit plans from time to time in effect
      for senior executives of the Bank and the Company. Such participation
      shall be subject to (i) the terms of the applicable plan documents, (ii)
      generally applicable Bank and Company policies and (iii) the discretion of
      the Board of Directors of the Bank and the Company or any administrative
      or other committee provided for in or contemplated by such plan. In
      addition, the Executive shall be entitled to receive benefits which are
      the same or substantially similar to those which are currently being
      provided to the Executive by the Bank and the Company, including without
      limitation use of an automobile appropriate for his position and
      membership in a country club or similar organization of his choice
      suitable for business entertainment.

            (c) Business Expenses. The Bank or the Company shall reimburse the
      Executive for all reasonable travel and other business expenses incurred
      by him in the performance of his duties and responsibilities, subject to
      such reasonable requirements with respect to substantiation and
      documentation as may be specified by the Bank or the Company.

            (d) Vacation. The Executive shall be entitled to not less than six
      weeks of vacation per year, to be taken at such times and intervals as
      shall be determined by the Executive with the approval of the Bank and the
      Company, which approval shall not be unreasonably withheld.

     5. Extent of Service. During his employment with either the Bank or the
Company, the Executive shall, subject to the direction and supervision of their
respective Boards of Directors, devote his full business time, best efforts and
business judgment, skill and knowledge to the advancement of the Bank's and the
Company's interests and to the discharge of his duties and responsibilities
hereunder. He shall not engage in any other business activity, except as may be
approved by the Boards of Directors; provided, however, that nothing herein
shall be construed as preventing the Executive from:

            (a) investing his assets in a manner not prohibited by Section 8(a)
      hereof, and in such form or manner as shall not require any material
      services on his part in the


                                        2


      operations or affairs of the companies or other entities in which such

      required to render any material services with respect to the operations or
      affairs of any such company; or

            (c) engaging in religious, charitable or other community or
      non-profit activities which do not impair his ability to fulfill his
      duties and responsibilities under this Agreement.

      6. Termination and Termination Benefits. Notwithstanding the provisions of
Section 3, the Executive's employment hereunder shall terminate under the
following circumstances:

            (a) Death. In the event of the Executive's death during the
      Executive's employment hereunder, the Executive's employment shall
      terminate on the date of his death; provided, however, that the Bank or
      the Company. shall continue to pay an amount equal to the Executive's
      salary to the Executive's beneficiary designated in writing to the Bank or
      the Company prior to his death (or to his estate, if he fails to make such
      designation) for a period of six months after the date of the Executive's
      death, at the salary rate in effect on the date of his death, without the
      increase provided for in Section 4(a), said payments to be made on the
      same periodic dates as salary payments would have been made to the
      Executive had he not died.

            (b) Termination for Cause. The Executive's employment with the Bank
      and the Company may be terminated without further liability on the part of
      the Bank or the Company effective immediately, by a two-thirds vote of all
      of the members of the Board of Directors of the Company and a two-thirds
      vote of all of the members of the Board of Directors of the Bank for cause
      by written notice to the Executive setting forth in reasonable detail the
      nature of such cause. Only the following shall constitute "cause" for such
      termination:

            (i) Deliberate dishonesty of the Executive with respect to the Bank
            or the Company or any subsidiary or affiliate thereof.

            (ii) Conviction of the Executive of a crime involving moral
            turpitude.

            (iii) Gross and willful failure to perform a substantial portion of
            his duties and responsibilities hereunder, which failure continues
            for more than thirty days after written notice given to the
            Executive pursuant to a two-thirds vote of all of the members of the
            Board of Directors of the Company and a two-thirds vote of


                                        3


            all of the members of the Board of Directors of the Bank, such vote
            to set forth in reasonable detail the nature of such failure.

            (c) Termination by the Executive. The Executive's employment with
      the Bank and the Company may be terminated, effective immediately, by the
      Executive by written notice to the Board of Directors of the Company and
      the Bank in the event of the following:

            (i) Failure of the Board of Directors of the Bank or the Company, as
            the case may be, to elect the Executive to the offices of Chairman,
            President and Chief Executive Officer of the Bank or the Company, as
            the case may be, or to continue the Executive in such offices; or

            (ii) Failure by the Bank or the Company to comply with the
            provisions of Section 4(a) or a material breach by the Bank or the
            Company of any other provision of this Agreement.

            (d) Termination Without Cause. The Executive's employment with the
      Bank and the Company may be terminated without cause by a two-thirds vote
      of all of the members of the Board of Director of the Company and a
      two-thirds vote of all of the members of the Board of Directors of the
      Bank on written notice to the Executive.

            (e) Certain Termination Benefits. In the event of termination
      pursuant to Sections 6(c) or (d), the Executive shall be entitled to the
      following benefits:

            (i) For the period subsequent to the date of termination until the
            Expiration Date, the Bank or the Company shall continue to pay the
            Executive a salary at the rate in effect on the date of termination,
            with increases as provided in Section 4(a).

            (ii) For the period subsequent to the date of termination until the
            Expiration Date, the Executive shall continue to receive all
            benefits described in Section 4(b) existing on the date of
            termination (except for any cash bonus plans which shall be
            pro-rated through the date of termination). For purposes of
            application of such benefits, the Executive shall be treated as if
            he had remained in the employ of the Bank and the Company with an
            annual salary at the rate in effect on the date of termination, with
            increases as provided in Section 4(a), and service credits will
            continue to accrue during such period as if the Executive had
            remained in the employ of the Bank and the Company.

            (iii) If, in spite of the provisions of Section 6(e)(ii) above,
            benefits or service credits under any benefit plan shall not be
            payable or provided under any such plan to the Executive, or to the
            Executive's dependents, beneficiaries or estate, because the
            Executive is no longer deemed to be an employee of the Bank and


                                        4


            the Company, the Bank or the Company itself shall pay or provide for
            payment of such benefits and service credits for such benefits to
            the Executive, or to the Executive's dependents, beneficiaries or
            estate.

            (f) Set-off. The Bank or the Company shall be entitled to set off
      against any cash compensation to be provided to the Executive under
      Section 6(e)(i) above one-half of the amount of any cash compensation
      received by the Executive from other employment during the period in which
      the Executive receives cash compensation under Section 6(e)(i). The
      Executive shall inform the Company of any such amounts of cash
      compensation and shall refund to the Bank or the Company, as the case may
      be, any amounts which the Bank or the Company, as the case may be, has
      paid which exceed the amounts due from the Bank or the Company, as the
      case may be, after application of the set-off provided for in this
      paragraph. Notwithstanding the foregoing and any other provision of this
      Agreement, the Executive shall be under no obligation to seek or accept
      any employment after termination of employment with the Bank and the
      Company for any reason.

      7. Disability. If, due to physical or mental illness, the Executive shall
be disabled so as to be unable to perform substantially all of his duties and
responsibilities hereunder, the Boards of Directors of the Company and the Bank,
as the case may be, may designate another executive to act in his place with
respect to the Company and the Bank, as the case may be, during the period of
such disability.

      Notwithstanding any such designation, the Executive shall continue to
receive his full salary and benefits under Section 4 of this Agreement from
either the Bank or the Company until he becomes eligible for disability income
under the Bank's or the Company's disability income plan. While receiving
disability income payments under such plan, the Executive shall not receive any
salary under Section 4(a), but shall continue to participate in those benefit
plans of the Bank and the Company in which the Executive was otherwise
participating and to receive other benefits as specified in Section 4 until the
Expiration Date. In the absence of a disability income plan at the time of such
disability, the Bank or the Company shall pay the Executive benefits equal to
those the Executive would have received if the Bank's and the Company's current
disability income plan were in effect at such time. If any question shall arise
as to whether during any period the Executive was disabled so as to be unable to
perform substantially all of his duties and responsibilities hereunder due to
physical or mental illness, the Executive may, and at the request of the Bank or
the Company will, submit to the Bank or the Company, as the case may be, a
certification in reasonable detail by a physician selected by the Executive or
his guardian to whom the Bank or the Company, as the case may be has no
reasonable objection as to whether the Executive was so disabled and such
certification shall for the purposes of this Agreement be conclusive of the
issue. If such question shall arise and the Executive shall fail to submit such
certification, the Bank's or the Company's determination, as the case may be, of
such issue shall be binding on the Executive.

      8.    Noncompetition and Confidential Information.


                                        5


            (a) Noncompetition.  During

                  (i) a period of one year following the date of termination of
            the Executive's employment with the Bank and the Company (x) by the
            Executive as a result of his election not to extend pursuant to
            Section 3 or (y) by the Bank and the Company for cause pursuant to
            Section 6(b) hereof or (z) by the Executive in the event that such
            termination constitutes a material breach by the Executive of any of
            the provisions of this Agreement, and

                  (ii) the period during which the Bank or the Company would be
            required to provide benefits to the Executive pursuant to Section
            6(e)(i)-(iii) hereof

      the Executive will not, directly or indirectly, whether as owner, partner,
      shareholder, consultant, agent, employee, co-venturer or otherwise, or
      through any Person (as defined in Section 11), compete in the Bank's or
      the Company's market area (defined as that portion of Massachusetts
      bounded to the west and north by Interstate 95 and to the south by
      Interstate 90) with the banking or any other business conducted by the
      Bank or the Company during the period of his employment with either the
      Bank or the Company, nor will he attempt to hire any employee of the Bank
      or the Company, assist in such hiring by any other Person, encourage any
      such employee to terminate his or her relationship with the Bank or the
      Company, or solicit or encourage any customer of the Bank or the Company
      to terminate its relationship with the Bank or the Company or to conduct
      with any other person any business or activity which such customer
      conducts or could conduct with the Bank or the Company.

            (b) Confidential Information. The Executive will not disclose to any
      other Person (except as required by applicable law or in connection with
      the performance of his duties and responsibilities hereunder), or use for
      his own benefit or gain, any confidential information of the Bank or the
      Company obtained by him incident to his employment with the Bank and the
      Company. The term "confidential information" includes, without limitation,
      financial information, business plans, prospects and opportunities (such
      as lending relationships, financial product developments, or possible
      acquisitions or dispositions of businesses or facilities) which have been
      discussed or considered by the Bank's or the Company's management but does
      not include any information which has become part of the public domain by
      means other than the Executive's non-observance of his obligations
      hereunder.

            (c) Relief; Interpretation. The Executive agrees that the Bank or
      the Company, either jointly or individually, shall be entitled to
      injunctive relief for any breach by him of the covenants contained in
      Sections 8(a) or 8(b). In the event that any provision of this Section 8
      shall be determined by any court of competent jurisdiction to be
      unenforceable by reason of its being extended over too great a period of
      time, too large a geographic area, or too great a range of activities, it
      shall be interpreted to extend only over the maximum period of time,
      geographic area, or range of activities as to


                                        6


      which it may be enforceable. For purposes of this Section 8, the term
      "Bank" shall mean the Bank and any of its subsidiaries and affiliates and
      the term Company shall mean the Company and any of its subsidiaries
      (except the Bank).

      9. Allocation of Obligations. The Bank and the Company shall allocate
among themselves which party shall be responsible for paying the salary and
other benefits required to be paid by Sections 4, 6(a), 6(e), 7 and 13 of this
Agreement. The payment by either party of such salary and other benefits shall
satisfy the obligations of the non-paying party under such Sections. Both the
Bank and the Company shall be jointly and severally liable in the event of a
failure by both parties to pay such salary and other benefits.

      10. Conflicting Agreements. The Executive hereby represents and warrants
that the execution of this Agreement and the performance of his obligations
hereunder will not breach or be in conflict with any other agreement to which he
is a party or is bound, and that he is not now subject to any covenants against
competition or similar covenants which would affect the performance of his
obligations hereunder.

      11. Definition of "Person". For purposes of this Agreement, the term
"Person" shall mean an individual, a corporation, an association, a partnership,
an estate, a trust and any other entity or organization.

      12. Withholding. All payments made by the Bank or the Company under this
Agreement shall be net of any tax or other amounts required to be withheld by
the Bank or the Company under applicable law.

      13. Arbitration of Disputes. 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 laws of the Commonwealth of Massachusetts by three
arbitrators, one of whom shall be appointed by the Company, one by the Executive
and the third by the first two arbitrators. If the first two arbitrators cannot
agree on the appointment of a third arbitrator, then the third arbitrator shall
be appointed by the American Arbitration Association in the City of Boston. Such
arbitration shall be conducted in the City of Boston in accordance with the
rules of the American Arbitration Association, except with respect to the
selection of arbitrators which shall be as provided in this Section 13. Judgment
upon the award rendered by the arbitrators may be entered in any court having
jurisdiction thereof. In the event that it shall be necessary or desirable for
the Executive to retain legal counsel and/or incur other costs and expenses in
connection with the enforcement of any or all of the Executive's rights under
this Agreement, the Bank or the Company shall pay (or the Executive shall be
entitled to recover from the Bank or the Company, as the case may be) the
Executive's reasonable attorneys' fees and other reasonable costs and expenses
in connection with the enforcement of said rights (including the enforcement of
any arbitration award in court) regardless of the final outcome, unless and to
the extent the arbitrators shall determine that under the circumstances recovery
by the Executive of all or a part of any such fees and costs and expenses would
be unjust.


                                        7


      14. Assignment; Successors and Assigns, etc. Neither the Bank, the Company
or the Executive may make any assignment of this Agreement or any interest
herein, by operation of law or otherwise, without the prior written consent of
the other party; provided, however, that the Bank or the Company may assign its
rights under this Agreement without the consent of the Executive in the event
the Bank or the Company shall hereafter effect a reorganization, consolidate
with or merge into any other Person, or transfer all or substantially all of its
properties or assets to any other Person. This Agreement shall inure to the
benefit of and be binding upon the Bank, the Company and the Executive, their
respective successors, executors, administrators, heirs and permitted assigns.
In the event of the Executive's death prior to the completion by the Bank or the
Company of all payments due him under this Agreement, the Bank or the Company
shall continue such payments to the Executive's beneficiary designated in
writing to the Bank or the Company prior to his death (or to his estate, if he
fails to make such designation).

      15. Enforceability. 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.

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

      17. Notices. Any notices, requests, demands and other communications
provided for by this Agreement shall be sufficient if in writing and delivered
in person or sent by registered or certified mail, postage prepaid, to the
Executive at the last address the Executive has filed in writing with the Bank
and the Company or, in the case of the Bank, at its main office, attention of
the Clerk or, in the case of the Company, at its principal place of business,
attention of the Clerk.

      18. Amendment. This Agreement may be amended or modified only by a written
instrument signed by the Executive and by a duly authorized representative of
the Executive Committee of each of the Boards of Directors of the Company and
the Bank.

      19. Governing Law. This is a Massachusetts contract and shall be construed
under and be governed in all respects by the laws of the Commonwealth of
Massachusetts.


                                        8


      IN WITNESS WHEREOF, this Agreement has been executed as a sealed
instrument by the Bank, by its duly authorized officer, by the Company, by its
duly authorized officer and by the Executive, as of the date first above
written.
