               accurate records thereof, and shall generally perform duties in
               the nature of those performed by the Clerk of a Massachusetts
               corporation. He shall have such other powers and perform such
               other duties as may be prescribed by the Declaration of Trust, by
               the Trustees, or elsewhere in these By-Laws, or by law.

               shall be sworn to the faithful performance of their duties. Such
               Assistant Secretaries shall have such powers and duties as may be
               delegated to them, or either of them, by the Secretary or by the
               President. In the absence of the Secretary or in the event of his
               death, resignation, or incapacity, except as the Trustees shall
               otherwise order, such Assistant Secretaries, or either of them,
               shall have the powers and perform the duties of the Secretary.

                                   ARTICLE II.

           SELECTION, TENURE AND ADDITIONAL QUALIFICATIONS OF OFFICERS
                             AND HONORARY TRUSTEES.

                    1. The Officers of the Association shall be elected annually
               at the Annual Meeting of the Trustees, and by ballot.

                    2. The Chairman and the President shall be elected from
               among the Trustees. Other officers need not be Trustees. No
               officer need be a Shareholder.

                    3. All officers shall hold their respective offices for one
               year and until the selection and qualification of their
               respective successors, except that any officer may be removed at
               any time by vote of, or resolution signed by, a majority of the
               Trustees, and except that an officer chosen to fill a vacancy
               shall hold office only until the next Annual Meeting of the
               Trustees and the qualification of his successor.

                    4. Any officer may be required to give bond for the faithful
               performance of his duties, in such amount and with such sureties
               as the Trustees shall determine, the premium of which bond shall
               be paid by the Association. In lieu of individual bonds, the
               Trustees may provide for a blanket fidelity bond covering all or
               certain officers and employees.

                    5. As provided in the Declaration of Trust as amended, the
               Trustee may elect one or more Honorary Trustees. An Honorary
               Trustee shall serve for the same term as Permanent Trustees. An
               Honorary Trustee shall receive the same compensation as the
               Permanent Trustees provided that an Honorary Trustee shall not be
               entitled to receive shares of beneficial interest in the trust as
               part of such compensation in any year following the year of his
               retirement.

                  VACANCIES AND SUBSTITUTE OFFICERS AND AGENTS.

                    1. The Trustees may at any time fill a vacancy which may
               occur for any reason in any office.

                    2. In the event that any officer or agent of the Association
               is absent or temporarily unable to perform his duties, then,
               except as otherwise provided in these By-Laws, the Trustees may
               designate any person to exercise the powers and perform the
               duties of such officer during the period of such absence or
               disability. A statement that such absence or disability exists
               contained in any vote of the Trustee conferring such authority
               shall be binding and conclusive in favor of all persons not
               acting in bad faith.

                                   ARTICLE IV.

                       AUTHORITY TO SIGN CHECKS AND NOTES.

                    Authority elsewhere conferred in these By-Laws relative to
               the signing of checks or oders for the withdrawal of funds of the
               Association by certain officers shall not preclude the Trustees
               from providing from time to time that such checks or orders may
               be signed on behalf of the Association by other persons; and any
               check or order for withdrawal of funds which is signed as
               authorized by vote of the Trustees may be honored and paid in the
               usual course of business.

                    Authority elsewhere conferred in these By-Laws relative to
               the signing of notes or other obligations of the Association by
               certain officers shall not preclude the Trustees from providing
               from time to time that such notes or other obligations for money
               borrowed may be signed on behalf of the Association by other
               officers, provided, however, that they bear the written approval
               of a Trustee other than the signer.

                                   ARTICLE V.

                    1. Regular meetings of the Trustees shall be held at such
               times and at such places as the Trustees may by vote from time to
               time determine.

                    2. The regular meeting of the Trustees which is held on the
               day of or next following the day of the Annual Meeting of the
               Shareholders, or of any meeting held in lieu thereof, shall be
               considered the Annual Meeting of the Trustees; and at such
               meeting the annual elections of officers shall be held,

                                        4
<Page>

               appointment of committees shall be made, and other general annual
               business shall be transacted.

                    3. The Chairman, the President or the Treasurer or any two
               Trustees shall have authority to convene any special meeting of
               the Trustees, and such meetings may be held at such time and
               place as shall be designated in the notice or waiver of notice of
               the meeting.

                    4. The procedure at meetings of the Trustees shall be such
               as shall from time to time be determined by them.

                    5. A majority of the Trustees shall constitute a quorum at
               any meeting, but a majority of those present, even though less
               than a quorum is present, may vote to adjourn.

                    6. The consent in writing of any Trustee to any vote or
               action shall have the same effect as if he were personally
               present at a legal meeting at which such action was authorized or
               such vote passed.

                    7. In addition, the Trustees or any committee thereof may
               act on all matters without meeting by resolution signed by all
               Trustees or committee members entitled to vote at a meeting and
               such resolution when so signed shall have the same force and
               effect as a vote duly passed at a meeting of the Trustees or the
               applicable committee.

                                   ARTICLE VI.

                               NOTICE OF MEETINGS.

                    1. Any Shareholder or Trustee present at any meeting shall
               be presumed to have received due notice thereof.

                    2. Any Shareholder or Trustee may waive notice of any
               meeting either before or after the meeting by a writing filed
               with the records of the meeting.

                    3. Any regular or special meeting of the Trustees shall be a
               legal meeting without notice if all the Trustees are present or
               if all the Trustees who are not present waive notice.

                    4. Any regular meeting, including the Annual Meeting, or the
               Trustees shall be presumed to have been duly called, and not
               further notice thereof shall be required, if such meeting is held
               on the day and at such hour and place as shall have been fixed by
               a vote taken at a previous meeting of the Trustees.

                                        5

                    5. Notices of meetings of the Trustees need not state the
               purposes of the meeting.

                    6. Any notice required by the Declaration of Trust or by
               these By-Laws may be given by mailing the same, postage prepaid,
               addressed to the person entitled thereto at his usual or last
               known place of business or residence as shown on the books of the
               Association, and such notice shall be deemed given at the time of
               such mailing.

                    7. When notice of a meeting of the Trustees is required,
               such notice may be given orally, in writing, or by telephone or
               telegram, and a notice of a meeting mailed, postage prepaid,
               addressed to a Trustee at his usual or last known place of
               business or residence at least three days before the date of the
               meeting shall be sufficient notice to such Trustee in any event.

                    8. If by reason of war or otherwise communication with a
               Shareholder or Trustee would be unlawful, notice to such
               Shareholder or Trustee of any meeting held during the period when
               such communication is unlawful shall not be requisite to the
               validity of such meeting.

                    9. It shall be the duty of the Secretary to give such
               notices of meetings as are required by these By-Laws, but in case
               of his absence, death, resignation, incapacity, or refusal to
               act, notice may be given by either the Assistant Secretary or the
               person or persons ordering the meeting.

                                  ARTICLE VII.

                                   COMMITTEES.

                    1. The Trustees shall at their Annual Meeting appoint from
               among their own number an Executive Committee, consisting of such
               number of Trustees as they shall determine, and such other
               committees as they shall determine.

Executive
Committee           2. Between meetings of the Trustees the Executive Committee
               shall have the same power to direct or limit action by any of the
               officers as the entire Board of Trustees would have, except in so
               far as the Trustee may by vote expressly prescribe otherwise.
               Without limiting the foregoing general powers, the Executive
               Committee may at any time, except as these By-Laws otherwise
               provide, designate a person to succeed temporarily to the powers
               and perform the duties of any officer or agent who is absent or
               disabled or where a vacancy exists for any reason; may determine
               whether the Trustees desire to consider the purchase of shares
               offered for transfer; and may waive or authorize waivers of
               restrictions on the transfer of shares.

                                        6
<Page>

                    The Executive Committee may choose their own presiding and
               recording officers and the manner of their proceedings and may
               act in meeting or otherwise, but shall cause a written record to
               be kept of their proceedings and decisions, which shall be
               available to all the Trustees at any time. Any member of the
               Committee present at any meeting shall be presumed to have
               received due notice thereof, and any member may waive notice; but
               whenever notice is required a notice given in the manner
               prescribed for meetings of Trustees shall be sufficient.

Other
Committees          3. Other committees shall consist of such number of Trustees
               and other members and have such powers as the Trustees may
               determine.

                                  ARTICLE VIII.

                          SHARES AND TRANSFERS THEREOF.

                    1. The beneficial interest in the trust property shall be
               divided into 1,000,000 shares. Such shares shall be evidenced by
               certificates substantially in the form prescribed by Article X of
               the Declaration of Trust.

                    2. Records of all certificates of shares outstanding shall
               be maintained by the Trustees, and for this purpose the Trustees
               may employ the services of a transfer agent or agents and
               delegate to it or them the customary powers exercised by transfer
               agents of corporations. The address of a Shareholder as appearing
               by said records may be presumed to be his registered address or
               last known address for purposes of all notices, dividends, and
               otherwise.

                    3. Certificates of shares shall be signed by the President
               and Secretary, and shall be countersigned by the Transfer Agent
               if one has been appointed at the time of issue.

                    4. The transfer of shares is subject to restrictions as set
               forth in Article VII of the Declaration of Trust. An offer to
               transfer shares to the Trustees shall be deemed received by the
               Trustees when received by the Treasurer's office. Upon receipt of
               such an offer, the Treasurer shall forthwith consult with the
               Trustees or the Executive Committee, who shall determine whether
               the Trustees desire to consider the purchase of such shares, and,
               if the decision is in the affirmative, he shall cause the
               Shareholder to be notified thereof within ten days from receipt
               of the offer, in which case proceedings shall be had as provided
               in said Article VII of the Declaration of Trust.

                    5. The Association may for all purposes presume that the
               registered holder of record of a certificate of shares is the
               absolute owner of the shares

                                        7

               represented thereby; and the Association shall not be obliged to
               see the execution of any trust, actual or constructive, to which
               any of the shares is subject.

                                   ARTICLE IX.

                       APPOINTMENT OF INDEPENDENT AUDITOR.

                    The Trustees shall at a regular meeting early in each fiscal
               year appoint an independent certified public accountant for that
               fiscal year who will examine and make an audit of the books and
               accounts of the Association, who will report to the Trustees from
               time to time as they may request or as the accountant may deem
               advisable, and who will render an opinion concerning financial
               statements of the Association, at such remuneration as may be
               determined and agreed by the accountant and the Trustees.

                                   ARTICLE X.

                                   AMENDMENTS.

                    These By-Laws may be amended, or repealed in whole or in
               part, and new or additional By-Laws may be adopted, from time to
               time, at any regular or special meeting of the Trustees, by vote
               of a majority of the Trustees, provided that notice of such
               meeting shall have been duly given and that such notice shall
               have specified that the matter of such repeal or amendment of, or
               adoption of an addition to, the By-Laws is to be acted upon, and
               provided that the By-Laws of the Company as existing after such
               repeal, amendment, and/or addition shall not be inconsistent with
               any provision of the Declaration of Trust.
