projecting the Executives compensation through age 65, assuming an annual increase in compensation of five percent (5%). At the election of the Executive submitted in writing to the Board of Directors not later than ninety (90) days prior to
the effective date of the Change in Control, the Executives Supplemental Benefit shall be payable (i) as provided in Section 2 of this Agreement, (ii) commencing on a date specified by the Executive, or (iii) in the form of a lump sum
distribution as provided in Section 5 of this Agreement.





Section 4.    Death Benefits.





4.1Beneficiary Designation.    The Executive shall have the right, at any time, to
designate any person or persons as his Beneficiary or Beneficiaries (both principal as well as contingent) to whom payment under this Agreement shall be paid in the event of his death prior to complete distribution of the Supplemental Benefit due
him under the Agreement. Any designation of a Beneficiary shall be made in a written instrument filed with the Company and shall be effective only when received in writing by the Company.





4.2Change of Beneficiary.    Any Beneficiary designation may be changed by the Executive by the written filing of such change on a
form prescribed by the Company. The filing of a new Beneficiary designation form will cancel all Beneficiary designations previously filed.





4.3No Beneficiary Designation.    If the Executive fails to designate a Beneficiary as provided above, or if all designated Beneficiaries predecease the
Executive, then the Executives designated Beneficiary shall be deemed to be the person or persons surviving him in the first of the following classes in which there is a survivor, share and share alike:





(a)  The surviving spouse;





(b)  The Executives children, except that if any of the children predecease the Executive but leave issue surviving, then such issue shall
take by right of representation the share their parent would have taken if living;





(c)  The Executives estate.





4.4Payments Upon
Death.    Upon the death of the Executive, the Bank shall pay to the Executives






---

Beneficiary an amount determined as follows:





(a)  If the Executive dies after benefit payments have commenced to him under the Agreement, then the Executives Beneficiary shall receive
the same payments that would have been made to the Executive had he survived until the last payment due to him was paid. If the Executive dies leaving more than one Beneficiary, the total payments made to the Beneficiaries shall equal, but not
exceed, in the aggregate, the payments that would have been made to the Executive had he not died.





(b)  If the Executive dies prior the commencement of benefit payments under this Agreement and the Beneficiary becomes entitled to a benefit under Section 3(c) of this Agreement, then the Executives Beneficiary shall
receive the payments that would have been made to the Executive had his date of death been his Retirement Date and had he survived until the last payment due to him was paid. If the Executive dies leaving more than one Beneficiary, the total
payments made to the Beneficiaries shall equal, but not exceed, in the aggregate, the payments that would have been made to the Executive had he not died.





Section 5.    Optional Forms of Payment.





Notwithstanding any
provision of this Agreement to the contrary, the present value of the sum of the Supplemental Benefit and the benefit to a Beneficiary (if any) may, at the request of the Executive and only with the consent of the Board of Directors, or at the
request of the surviving Beneficiary and only with the consent of the Board of Directors, be payable in cash in a lump sum within ninety (90) days following the date the benefits otherwise become payable under this Agreement. Such present value
shall be the actuarial equivalent of the Supplemental Benefit (if any) determined by reference to reasonable actuarial factors consistent with the requirements of Section 417(e) of the Code. The request for a lump sum distribution must be filed by
the Executive with the Board of Directors at least thirty (30) days prior to the scheduled date of a benefit payment. Such consent shall be in writing on a form provided by the Board of Directors.





Section 6.    Termination for Cause.





Notwithstanding any provision of this Agreement to the contrary, no Supplemental Benefit shall be payable hereunder in the event of the Executives termination for Just Cause.





Section 7.  Miscellaneous.





(a)  The Supplemental Benefit shall cease to be paid to the Executive (and rights to any benefit to a Beneficiary shall terminate) if the Executive discloses material confidential information
or trade secrets concerning the Bank, the Company or any of their subsidiaries without the consent of the Bank or the Company, or if the Executive engages in any activity that is materially damaging to the Bank or the Company. The Board of Directors
shall have authority to cease payments under this paragraph (a), and the determination of the Board of Directors shall be final and conclusive. Upon the request of the Executive, the Board of Directors may grant an advance opinion as to whether a
proposed activity would violate the provisions of this paragraph (a).





(b)  Nothing in this Agreement
shall be construed as giving the Executive the right to be retained in the employ of the Bank or any subsidiary of the Bank at all or for any specified period in any particular position, or any right to any payment whatsoever except to the extent
provided for by this Agreement.






---

(c)  Notwithstanding any other provisions hereof, if any person entitled to receive payments hereunder (the
recipient) shall be physically or mentally or legally incapable of receiving or acknowledging receipt of such payment, the Bank, upon the receipt of satisfactory evidence that another person or institution is maintaining the recipient
and that no guardian or committee has been appointed for the recipient, may cause such payment to be made to such person or institution so maintaining the recipient.





(d)  Nothing in this Agreement and no action taken pursuant to the provisions of this Agreement shall create or shall be construed as creating a trust of any
kind, or a fiduciary relationship between the Bank and the Executive or any other person. Any amounts which are or may be set aside hereunder shall continue for all purposes to be a part of the general funds of the Bank, and no person other than the
Bank shall, by virtue of the provisions of this Agreement, have any interest in such funds. To the extent that any person acquires a right to receive payments from the Bank hereunder, such right shall be no greater than the right of any unsecured
general creditor of the Bank.





(e)  The benefits payable under this Agreement may not be assigned by the
Executive or any other person nor anticipated in any way.





(f)  This Agreement may not be amended,
altered or modified, except by a written instrument signed by the parties hereto, or their respective successors or assigns.





(g)  This Agreement shall be governed by and construed in accordance with the laws of Massachusetts, to the extent not preempted by applicable federal law.





(h)  All notices hereunder shall be in writing and deemed properly given if delivered by hand and receipted or if mailed by registered mail, return receipt
requested. Notices to the Bank shall be directed to the Secretary of the Bank. Notices to the Executive shall be directed to his last known address. Notice may not be provided by e-mail.





(i)  This Agreement shall be binding upon the Executive, the Bank and their successors and assigns.





Section 8.    Administration.





(a)  This Agreement shall be administered by the Board of Directors. The Board of Directors shall interpret this Agreement, establish regulations to further the purposes of this Agreement and take any other action necessary
to the proper operation of this Agreement. Prior to paying any benefit under this Agreement, the Board of Directors may require the Executive or his Beneficiary to provide such information or material as the Bank, in its sole discretion, shall deem
necessary for it to make any determination it may be required to make under this Agreement.





(b)  If for
any reason a benefit payable under this Agreement is not paid when due, the Executive or his Beneficiary may file a written claim with the Board of Directors. If the claim is denied or no response is received within forty-five (45) days after the
date on which the claim was filed with the Board of Directors (in which case the claim will be deemed to have been denied), the Executive or his Beneficiary may appeal the denial to the Board of Directors within sixty (60) days of receipt of written
notification of the denial or the end of the forty-five day period, whichever occurs first. In pursuing an appeal, the Executive or his Beneficiary may request that the Board of Directors review the denial, may review pertinent documents, and may
submit issues and documents in writing to the Board of




---

Directors. A decision on appeal will be made within thirty (30) days after the appeal is made, unless special circumstances require the Board of Directors to extend the period for another thirty
(30) days.





(c)  The Board of Directors may appoint one or more persons to act as administrator and
delegate its administrative responsibilities to such administrator.





(d)  It is acknowledged by the Bank
that the procedures set forth in Section 8(b) are not the exclusive remedy available to the Executive or his beneficiaries in the event of a dispute over the interpretation of this Agreement.





IN WITNESS WHEREOF, this Agreement has been executed in behalf of the Bank by its duly authorized officers and by the Executive as of the day and year first
above stated.
