or on any other date in 2003 upon which the COMPANY's Annual Meeting is held,
and ending on and including January 28, 2008, or on any other date in 2008 upon

Nominating Committee of the Board of Directors (hereafter, the BOD) of the
COMPANY (hereinafter, the Nominating Committee), said vote to be cast at the
Annual Meeting or a Special Meeting of the shareholders of the COMPANY in which
the shareholders are electing the directors of the COMPANY. So long as all of
the conditions in Section 2 hereof are satisfied, the TRUST shall be present by
proxy at all meetings of shareholders of the COMPANY so that all shares of stock

quorum at such meetings.

corporate position at the vice-presidential level (or similar title as mutually

Andrew Chase terminates his employment with the COMPANY, (iii) the COMPANY
terminates Andrew Chase's employment, (iv) or the TRUST elects to waive the
provisions of Section 2 as to Andrew Chase, the TRUST, in accordance with the

Edward L. Chase, reasonably acceptable to the Nominating Committee, to serve as
its representative on the BOD, and said lineal descendent will be nominated by
the Nominating Committee for a directorship.

     Section 4. In the event that all of the conditions set forth in Section 2
above are not satisfied, the TRUST is immediately relieved of its obligation to
vote all of the shares of the outstanding voting stock of the COMPANY which it
directly controls, manages or administers in favor of the slate of directors
recommended by the Nominating Committee of the COMPANY.

     Section 5. So long as all of the conditions set forth in Section 2 above
are satisfied, and so long as Andrew Chase remains a director of the COMPANY,
unless the TRUST otherwise determines, Andrew Chase will be regarded by the
TRUST as its representative on the BOD. Should Andrew Chase cease to serve as
director of the COMPANY or should Andrew Chase be removed as director of the
COMPANY or should Andrew Chase not be elected a director of the COMPANY, the
TRUST will designate another lineal descendant of Edward L. Chase to serve as
its representative on the BOD.

outstanding shares of any class of the COMPANY's stock.

herein do not affect, nor impair in any way, the right and the ability of the
TRUST to sell the shares of COMPANY stock which it directly controls, manages or
administers.

                           Code and if the limits under Section 415 of the Code

         commence benefit payments under the Pension Plan pursuant to Section
         401(a)(9) of the Code, benefits shall not commence under this Article

         (a)      If a Participant's contributions under the Savings Plan are
                  limited as a result of the limits under Section 401(a)(17) of
                  the Code, such Participant may participate hereunder by
                  electing, prior to the calendar year in which the election
                  shall become effective, to defer a portion of his Compensation
                  equal to the excess of (i) over (ii), where:

                  (i)      is the amount which the Participant would have
                           contributed under the Savings Plan if the definition
                           of compensation under the Savings Plan included
                           Compensation in excess of Section 401 (a)(17) of the
                           Code;

                  (ii)     is the amount actually contributed by the Participant
                           under the Savings Plan.

         The amount of Compensation deferred by the Participant pursuant to this
         paragraph (a) shall be credited to an account established for the
         Participant under this Plan (his "Supplemental Employee Contribution
         Account ").

         (b)      If a Participant's contributions under the Savings Plan are
                  limited by the restrictions of Section 401(a)(17) of the Code,
                  and the Participant thereby makes Supplemental Employee
                  Contributions pursuant to paragraph (a) above, the Employer
                  shall credit to an account established for the Participant
                  under this Plan (his "Supplemental Company Contribution
                  Account"), an amount equal to the Employer matching:
                  contribution which would have been made pursuant to the
                  Savings Plan if the Participant's Supplemental Employee
                  Contributions had been made pursuant to the Savings Plan.

         The Participant's Supplemental Employee Contribution Account and/or
         Supplemental Company Contribution Account shall be adjusted at the end
         of each calendar quarter to reflect a rate of return determined as if
         such accounts were invested at a rate which is one percent (1%) higher
         than the prime interest rate as reported by the Wall Street Journal at
         the beginning of the quarter.

         Benefits shall commence under this Article to a Participant as of the
         same date that benefits commence to a Participant under the Savings
         Plan; provided, however, that, in the case of a Participant required to
         commence benefit payments under the Savings Plan pursuant to Section
         401(a)(9) of the Code, benefits shall not commence under this Article
         until the Participant actually retires.
