                                 DEATH BENEFITS

3.1  Death Benefit. If a Participant dies prior to his Retirement Date, his
     designated Beneficiary will be paid, commencing on the first day of the

     Form of Payment provided in Section A9 of the Adoption Agreement.

     If a Beneficiary dies prior to receiving all benefits available under the
     Optional Form of Payment, the remaining benefits shall be made to the
     person or persons named by the Beneficiary to receive the benefits payable
     under such Optional Form of Payment or to the Beneficiary's estate if no
     such person is named. If the Participant is not survived by a named
     Beneficiary, or if the Board is in doubt as to the effective status of a
     Beneficiary designation, then the Death Benefit provided by this Section
     3.1 shall be paid to the Participant's estate in one lump sum.

3.2  Designation of Beneficiary. The Participant shall have the right to
     designate a Beneficiary, including a contingent beneficiary, entitled to

     Participant may change such designation from time to time and may revoke
     such designation.

3.3  Death of Participant After Retirement or Termination of Employment. Upon
     the death of the Participant after retirement or other termination of
     employment, no benefits will be payable to the Participant's Beneficiary or

     Pension or Optional Form of Payment in effect or elected under Section 2.3
     or 2.4 of this Plan provides a death benefit.

4.1  Disability Benefits.  If the Participant is unable to continue in the
     employ of the Employer by reason of Disability, the Participant shall be
     entitled to receive a Disability Benefit, in lieu of all other benefits

     such determination of Disability, payable in monthly installments, in an
     amount equal to the amount elected in A10 of the Adoption Agreement.
     Distribution may be in any form provided in A11 of the Adoption Agreement.

4.2  Return to Work.  In the event the Participant returns to work after
     receiving Disability Benefits, Disability Benefits shall cease and the
     Participant shall continue in this Plan as though such disability had not
     occurred. Accrued benefits payable under the Plan thereafter shall be
     determined on the basis of the Participant's total Years of Service and
     shall be adjusted to take into account the Actuarial Equivalent of the
     Disability Benefits, if any, previously paid to the Participant.

5.1  Investment.  All payments of amounts under the Plan shall be paid from the
     general funds of the Employer and no special or separate fund shall
     necessarily be established and no other segregation of assets shall
     necessarily be made to assure the payment of such amounts. Neither
     Participants nor their beneficiaries or estates shall have any right,
     title, or interest whatever in or to any investments, including any
     "Applicable Policy", which the Employer may make to aid it in meeting its
     obligation hereunder. To the extent that any person acquires any right to
     receive payments from the Employer under the Plan, such right shall be no
     greater than the right of an unsecured general creditor of the Employer.
     Notwithstanding the foregoing, nothing in the Plan document shall preclude
     the Employer from contributing to or making Plan payments from a Rabbi
     Trust, as elected in the Adoption Agreement.

     or manner prior to actual or constructive receipt thereof.

6.2  Amendment by Employer. The Employer may amend the Adoption Agreement by
     selecting any of its elective provisions. The amendment may not reduce the

     amendment shall be delivered to the Participants and Beneficiaries and to
     the Plan Administrator.

6.3  Expenses. The Employer will pay all Expenses of the Plan.

6.4  Limitation. The establishment of this Plan, or the payment of benefits,

     the right to be retained in the service of the Employer.

     This Plan shall be governed by, and shall be construed and interpreted in
     accordance with, applicable federal law and with the laws of the
     Commonwealth of Massachusetts.

     The Accrued Benefit of any individual under the Plan shall be reduced by
     the amount, if any, by which the cash value or the death proceeds under any
     Applicable Policy maintained by the Employer with respect to such
     individual's benefits is reduced as a result of any misstatement or other
     action or omission by the Participant to which such Applicable Policy
     relates or by any such other individual.

     In the event that any one or more of the provisions of this Plan shall be
     held to be invalid, illegal or unenforceable, the validity, legality and
     enforceability of the remaining provisions shall not in any way be affected
     or impaired thereby and the invalidated provision shall be automatically
     amended to the extent necessary to make it valid consistent with the intent
     of the Employer hereunder.

6.5  Change of Control. A Participant shall be immediately vested in the total
     amount credited to his Accrued Benefit in the event of a change of control
     of the Employer, and such amount will be immediately distributable to the
     Participant. A change of control for this purpose shall be deemed to occur
     upon the purchase or other acquisition by any person, entity, or group of
     persons, within the meaning of section 13(d) or 14(d) of the Securities
     Exchange Act of 1934 ("Act"), or any comparable successor provisions, of
     beneficial ownership (within the meaning of Rule 13d-3 promulgated under
     the Act) of 50 percent or more of either the outstanding shares of common
     stock or the combined voting power of the Employer's then outstanding
     voting securities entitled to vote generally, or the approval by the
     stockholders of the Employer of a reorganization, merger, or consolidation,
     in each case, with respect to which persons who were stockholders of the
     Employer immediately prior to such reorganization, merger, or
     consolidation, do not immediately thereafter, own more than 50 percent of
     the combined voting power entitled to vote generally in the election of
     directors of the reorganized, merged, or consolidated Employer's then
     outstanding securities, or a liquidation or dissolution of the Employer of
     the sale of all or substantially all of the Employer's assets.

6.6  Violation of Agreement. In the event that the Participant violates any of
     the terms of this Plan, the Employer, in addition to any other rights which
     it may have, shall be relieved of the liability to make any further
     payments under the Plan to, or on behalf of, the Participant and shall have
     the right to specifically enforce this Plan by proceedings in equity.

6.7  For Cause Clause. As elected in Section A13(a) of the Adoption Agreement,
     all of a Participant's benefits under this Plan will be forfeited if the
     Participant's employment is terminated for cause. The Corporation shall
     have "cause" to terminate the Participant's employment hereunder because of
     the Participant's personal dishonesty, incompetence, willful misconduct,
     breach of fiduciary duty involving personal profit, intentional failure to
     perform stated duties, willful violation of any law, rule or regulation
     involving moral turpitude or final cease and desist order, or material
     breach of any provision of this Agreement. For purposes of this Section, no
     act or failure to act on the Participant's part will be considered
     "willful" unless done, or admitted to be done, by him in bad faith and
     without reasonable belief that his action or omission was in the best
     interests of the Employer; provided that any act or omission to act by the
     Participant in reliance upon an opinion of counsel to the Employer shall
     not be deemed to be willful. Notwithstanding the foregoing, the Participant
     shall not be deemed to have been terminated for cause unless and until
     there shall have been delivered to him a copy of a certification by the
     Clerk of the Corporation that three-fourths (3/4) of the entire Board of
     Directors of the Employer found in good faith that the Participant was
     guilty of conduct which is deemed to be Cause as defined above and
     specifying the particulars thereof, after reasonable notice to the
     Participant and an opportunity for him together with his counsel, to be
     heard before such majority.

6.8  Non-Compete Clause. If the Non-Compete Clause is elected in Section A 13(b)
     of the Adoption Agreement, the Participant must not violate the terms of
     this Section 6.8.

     After becoming a Participant in this Plan, and for the period after
     termination of employment with the Employer as elected in Section A13(b) of
     the Adoption Agreement, the Participant may not be an employee or
     consultant of, or hold any other position with, or directly or indirectly
     assist, any bank in connection with any banking activities by said bank in
     the same county where the Participant's Employer has a branch; nor will the
     Participant attempt to hire any employee of the Employer, assist in such
     hiring by any other person or entity, encourage any such employee to
     terminate his or her relationship with the Employer, or solicit or
     encourage any customer of the Employer to terminate its relationship with
     the Employer or to conduct with any other person or entity any business or
     activity which such customer conducts or could conduct with the Employer;
     provided, however, that nothing herein shall prohibit the Participant
     from owning up to 2% of the shares of common stock of any bank whose shares
     are publicly traded on a national securities exchange or in the
     over-the-counter market.
