      Section 4.-No Shareholder, officer or agent of this trust shall be held
to any liability for the payment of any sum of money or for damages for the
non-performance of anything that shall have been agreed upon on behalf of this
trust by the Trustees or any officer or agent, or in tort or otherwise, and no
Trustee shall be held to any such liability unless expressly stipulated to

the Shareholders for the payment of any sum of money or any assessment
whatever, except only in the case of Shares in this trust which are by their

                                 The Trustees.

      Section 6.-At least two-thirds of the Trustees hereunder shall at all
times be residents of Massachusetts. The number of Trustees shall be nine (9).
Subject to the provisions of Section 22 hereof, the Trustees shall be elected
by plurality vote of Shareholders entitled to vote and the Board of Trustees
shall be divided into three classes of three Trustees each, with the term of
office of one class expiring each year. At the annual meeting of Shareholders
in 1987, three Trustees of the first class (Class A) shall be elected to hold
office for a term expiring at the 1988 annual meeting of Shareholders and
until their respective successors are chosen and qualified, three Trustees of
the second class (Class B) shall be elected to hold office for a term expiring
at the 1989 annual meeting of Shareholders and until their respective

<PAGE 13>
successors are chosen and qualified, and three Trustees of the third class
(Class C) shall be elected to hold office for a term expiring at the 1990
annual meeting of Shareholders and until their respective successors are
chosen and qualified. Commencing with the annual meeting of Shareholders in
1988, each class of Trustees whose term shall then expire shall be elected to
hold office for a three year term and until the election and qualification of
their respective successors in office.  A Trustee may but need not be a
Shareholder. Any vacancy or vacancies in the number of Trustees may be filled
by a majority of the remaining Trustees by written instrument filed at the
principal office of this trust, and any Trustee so chosen shall continue in
office until the next succeeding annual meeting of Shareholders at which the
class for which such Trustee has been chosen is subject to election; provided,
however, that any vacancy or vacancies in the number of Trustees elected by a
class of voters under the provisions of Section 22 shall be filled by the
remaining Trustee or Trustees elected by such class. Until any such vacancy is
filled, the remaining Trustees may exercise all the powers, authorities and
discretions of the Trustees hereunder by a majority of their number as
hereinafter provided.

      A Trustee may resign by delivering his resignation in writing at the
principal office of this trust, addressed to the remaining Trustees or by
delivering such resignation at a meeting of the Trustees or to the secretary
of this trust but such resignation shall take effect only upon its acceptance
by the remaining Trustees or upon the appointment of a new Trustee in his
place or upon the expiration of thirty (30) days after the delivery of the
said resignation, whichever event shall first occur, and after such
resignation, until it takes effect, the retiring Trustee may but shall not be
obliged to continue to act as one of the Trustees hereunder. Each Trustee
shall receive, for his services as such Trustee, such annual compensation,
plus such fees for each Trustees' meeting attended and additional services
rendered, as are fixed from time to time by the Trustees in their discretion. 

      Notwithstanding any other provisions of this Declaration of Trust (and
notwithstanding the fact that a lesser proportion or separate class vote may
be specified by law or this Declaration of Trust generally), the affirmative
vote or written consent of the holders of three-quarters of the then
outstanding Shares entitled to vote shall be required to amend or repeal, or
adopt any provisions inconsistent with this Section 6 including, without
limitation, provisions affecting the number, classes, term or incumbency of
Trustees. 

      Section 7.-Upon the resignation of any Trustee and upon the appointment
of a new Trustee such instruments shall be executed, acknowledged and
delivered as the Trustees or the new Trustee shall deem to be necessary or
convenient for vesting the Trust Property in the Trustees for the time being
or providing evidence of such vesting independently of such resignation or
appointment. But without the execution of any conveyance, the Trust Property
shall always (not restricting the same to the above enumerated cases) vest in
the Trustee or Trustees for the time being acting hereunder.

      Section 8.-The Trustees shall have power to determine whether any moneys
or things are for the purposes of these presents to be considered as capital
or income, and what constitutes the income of this trust for any year or other
period, and in what manner any expenses or outgoings are to be borne as
between capital and income. In making any such determination, the Trustees
shall be guided by sound accounting principles but every such determination
made in good faith, whether express or implied in the acts or proceedings of
the Trustees, shall be conclusive and binding upon all persons interested.

      Section 9.-Subject to the provisions contained in the rights,
preferences and limitations relating to any preferred shares in or any bonds
or other obligations of this trust, the Trustees may from time to time in
their discretion declare cash dividends out of earned surplus of the trust
accumulated subsequent to the effective date of the Plan; provided that
dividends in securities or rights or property or in shares of the System may
be declared as long as the payment of such dividend does not result in the
impairment of the capital of this trust, as represented by the aggregate of

<PAGE 14>

the par value of its outstanding shares and any cash premium paid in on the
sale of such shares; but no Shareholder shall have any right to any dividends
except when and as the same are declared by the Trustees, and no Shareholder,
Trustee, officer or agent of this trust shall be liable therefor, and any
Shareholder entitled thereto shall look only to the Trust Property for the
payment of any such dividends. For the purpose of determining the Shareholders
who are entitled to receive payment of any dividend, the register and transfer
books of this trust may be closed at the end of such day as the Trustees shall
direct, but not more than forty-five (45) days before the payment date for
such dividend, which register and transfer books, unless the Trustees
otherwise direct, shall remain closed until the close of business on said
dividend payment date, or without closing of said register and transfer books
the Trustees may fix a time not more than forty-five (45) days before any
dividend payment date as the time as of which the Shareholders entitled to
receive payment of such dividend shall be determined, and if such time is so
fixed only those Shareholders of record at such time shall be entitled to
receive payment of such dividend.

      Section 10.-The Trustees may determine the fiscal year of this trust,
and the form in which the accounts of this trust shall be kept, and may from
time to time change the fiscal year or form of accounts, provided, however,
that such accounts shall be kept in accordance with sound accounting
principles. Until the Trustees shall change the same the fiscal year shall end
on the thirty-first day of December in each year.

                         Proceedings of the Trustees.

      Section 11.-The Trustees, if more than one, may hold meetings for the
transaction of the business of this trust and the exercise of any of their
powers, authorities and discretions hereunder, and may prescribe regulations
for the conduct of such meetings, the times and places of regular meetings,
which may be held without call or further notice thereof, and the manner of
calling and giving and waiving of notice of special meetings. An annual
meeting of the Trustees shall be held in Cambridge, Massachusetts, as soon as
practicable after the annual meeting of the Shareholders, or any special
meeting held in lieu thereof, at which meeting action shall be taken on the
question that may be presented. No notice need be given of any meeting of the
Trustees provided that all the Trustees are present in person or waive notice
thereof in writing signed either before or after said meeting. A majority of
the Trustees shall constitute a quorum for the transaction of business, but a
lesser number may adjourn any meeting from time to time and the meeting may be
held as adjourned without further notice. Except as otherwise provided herein,
questions arising at any meeting of the Trustees at which a quorum is present
shall be decided by the vote or resolution of a majority present and such
majority shall have full power to exercise all or any of the duties, powers,
authorities and discretions at the time vested in their entire number.

      Section 12.-The Trustees may, without a meeting, transact any business
of the trust and exercise any of their duties, powers, authorities and
discretions hereunder by vote or resolution signed by each of the Trustees and
any such written vote or resolution shall be as valid for all purposes as
action taken at a meeting. 

      Section 13.-The Trustees shall cause to be kept by the secretary or an
assistant or temporary secretary, in books provided for the purpose, minutes
of all meetings of the Trustees, specifying the names of the Trustees present,
and a record of all written votes and resolutions adopted by the Trustees, and
minutes of all meetings of the Shareholders, and a record of all written
consents of the Shareholders. Such minutes and records, if signed or certified
by the secretary or any assistant or temporary secretary, or in case of
Trustees' action by a majority of the Trustees who were present in person at
the meeting or who signed the written vote or resolution, shall be conclusive
evidence of the matters therein stated. A certificate signed by the president
or a vice-president or the treasurer or the secretary or an assistant or
temporary secretary shall be conclusive evidence, in favor of every person,
firm, association, trust and corporation acting in good faith in reliance
thereon, as to the contents of any such vote or resolution or written consent
and as to all matters in such certificate contained relating to a written vote

<PAGE 15>


or resolution or written consent or relating to the meeting, if any, at which
such vote or resolution is therein certified to have been passed, including
the regularity of the said meeting and the passage of any vote or resolution
thereat, and as to all other matters and things stated in such certificate,
and no person, firm, association, trust or corporation shall be obliged to
make any inquiry as to any of the said matters, or as to the election or
appointment of any person acting at any such meeting or signing such vote or
resolution, or as to the holding of any Shares by any person, firm,
association, trust or corporation, acting as a Shareholder at such meeting or
signing such written consent, or be affected by actual or implied notice of
any irregularity whatsoever therein.

                   Officers: Depositaries and Other Agents.

      Section 14.-The Trustees shall at their annual meeting elect a
president, a treasurer and a secretary and may at that or any other meeting
elect any other officers which they may consider necessary or desirable and
may permit any officer to resign and may remove any officer with or without
cause and may fill any vacancy and may elect temporary officers to serve
during the absence or disability of regular officers or for a specified
purpose and may likewise from time to time appoint or employ or authorize the
appointment or employment of agents, employees, or representatives of this
trust, may fix the compensation, term of employment, duties and powers of all
officers, agents, employees or representatives of this trust or authorize the
same to be fixed, and may remove them or terminate their employment or
authorize the same to be done. Any action taken and any obligations entered
into by such officers or agents on behalf of this trust pursuant to authority
to them granted shall be binding upon the Trust Property. All of the said
officers shall, unless otherwise determined by the Trustees, continue in
office until the first annual meeting of the Trustees following the meeting at
which such officers were elected, and until their successors are elected.
Subject to the limitations contained in Section 4 and in this Section, the
several officers shall have such authority and perform such duties and receive
such compensation, if any, as may from time to time be fixed by the Trustees,
and unless the Trustees otherwise determine, but subject to the same
limitations, they shall have the authority and perform the duties usually
incident to their respective offices in the case of corporations. In addition
to all other duties, the treasurer, under the supervision of the Trustees,
shall keep or cause to be kept accurate books of account, which shall be the
property of this trust and shall constitute the books of account of the
Trustees, and the secretary shall attend and keep minutes of all meetings of
the Trustees and Shareholders, and shall keep records of all written consents
of the Shareholders presented to him for that purpose, which books of account,
minutes and records shall at all times be open to the inspection of any
Trustee and of any officer. The minutes of the meetings and records of the
written consents of the Shareholders shall be open during business hours to
the inspection of the Shareholders. In the absence of the secretary, an
assistant secretary or temporary secretary shall perform the duties of the
secretary. Any officer may but need not be a Shareholder, or Trustee, and any
two or more offices may be held by the same person, except that the offices of
president and treasurer may not be held by the same individual.

      Section 15.-The Trustees may appoint as Depositary or Depositaries
hereunder such national banks, state banks or trust companies doing business
in Boston, Massachusetts, or elsewhere, as they shall from time to time
select. Until its appointment is terminated as hereinafter provided, State
Street Trust Company, Boston, Massachusetts, shall be the principal Depositary
hereunder. Each Depositary shall have the custody of at least one duplicate
original or certified copy of this declaration of trust and of each
certificate of amendment, alteration, addition or rescission all of which
shall be available for inspection by the Shareholders during business hours.
Any Depositary may serve as Trustee under any indenture of trust issued
pursuant to the provisions hereof, registrar, transfer agent or other agent of
this trust, and may be changed or removed from time to time by the Trustees.
Any Depositary so removed or resigning shall turn over on demand to its
successor Depositary, or if none be selected, to the Trustees, all documents


<PAGE 16>


and records in its possession or custody relating to this trust, or shall at
the request of the Trustees record any such document in any place of public
record selected by the Trustees; and thereupon its duty as to such documents
and records and its liability therefor hereunder shall cease. Any funds of
this trust in the hands of any Depositary as such may be deposited by it in
its banking department for its account as Depositary hereunder, and any
securities of this trust in the hands of any Depositary may be deposited by it
in its safekeeping or safe-deposit department. Copies of all documents and
records in the custody of any such Depositary duly certified by it and
certificates as to who are the Trustees, signed by any officer of such
Depositary, shall be conclusive upon all questions as to title or affecting
the rights of third persons, and in general shall have the effect of their
originals. The Depositary shall for all purposes hereof be deemed an agent of
this trust.

            General Provisions Concerning the Trustees and Others.

      Section 16.-Notwithstanding any other provisions of this instrument, no
Trustee (except to the extent that directors of a Massachusetts business
corporation are liable) and no officer, agent or other representative
appointed pursuant to any provision hereof shall be liable for any act or
default on the part of any co-Trustee, or any other officer, agent, attorney,
employee or representative, or for having permitted any co-Trustee, officer,
agent, attorney, employee or representative to receive or retain any money or
property receivable by the Trustees hereunder, or for errors of judgment made
in good faith in exercising or failing to exercise any of the duties, powers,
authorities or discretions conferred upon or resting upon him, or for any loss
arising out of any investment, or for failure to sue for or to collect any
moneys or property belonging to this trust or for any act or omission to act,
performed or omitted by him in good faith in the execution of this trust; but
each Trustee and each such officer, agent or representative shall be entitled
out of the Trust Property to reimbursement for his reasonable expenses and
outlays and to be put in funds and exonerated and indemnified to his
reasonable satisfaction from time to time against any and all loss, costs,
expense and liability incurred or to be incurred by him in good faith in the
execution of this trust. And no Trustee, however appointed, shall be obliged
to give any bond or surety or other security for the performance of any of his
duties as Trustee.

      The System shall reimburse or indemnify each present and future Trustee,
officer, agent or representative (and his heirs, executors and administrators)
for or against all expenses reasonably incurred by him or imposed by him,
subsequent to the effective date of the Plan, in connection with, or arising
out of, any action, suit or proceeding in which he may be involved by reason
of his being or having been a Trustee, officer, agent or representative of the
System, where disposition of such action, suit or proceeding is made in favor
of such Trustee, officer, agent or representative; provided that no
reimbursement shall be made until such time has elapsed that appeal can no
longer be taken and that, in the judgment of the Trustees, such action, suit
or proceeding will not be recommended.

      No Trustee, officer, agent or representative of the System (or its or
his successors, heirs, executors or administrators) shall be liable for any
act, omission, step or conduct taken or had in good faith which (whether by
condition or otherwise) is required, authorized or approved by any order or
orders issued pursuant to the Public Utility Holding Company Act of 1935, the
Federal Power Act or any state statute regulating the System or its
subsidiaries by reason of their being public utility companies or public
utility holding companies, or any amendments to any thereof. In any action, 


<PAGE 17>


suit or proceeding based on any act, omission, step or conduct, as in this
paragraph described, the provisions hereof shall be brought to the attention
of the court. In the event that the foregoing provisions of this paragraph are
found by the court not to constitute a valid defense on the grounds of not
being applicable to the particular class of plaintiff, each such Trustee,
officer, agent or representative (and its and his successors, heirs, executors
and administrators) shall be reimbursed for, or indemnified against, all
expenses and liabilities incurred by him or imposed on him, in connection
with, or arising out of, any such action, suit or proceeding based on any act,
omission, step or conduct taken or had in good faith as in this paragraph
described. Such expenses and liabilities shall include, but shall not be
limited to, judgments, court costs and attorneys' fees.

      The foregoing rights shall not be exclusive of other rights to which any
Trustee, officer, agent or representative may otherwise be entitled and shall
be available whether or not the Trustee, officer, agent or representative
continues to be such at the time of incurring such expenses and liabilities.
Such other rights shall include, as to transactions subsequent to the
effective date of the Plan which are not within the protection afforded by the
foregoing paragraphs, the immunities and rights of reimbursement which would
have been allowable under the laws of The Commonwealth of Massachusetts had
this trust been a business corporation organized under such laws. As to
transactions on or prior to the effective date of said Plan, the immunities
and rights of reimbursement of any Trustee, officer, agent or representative
of the System (and its or his successors, heirs, executors and administrators)
shall be determined under the provisions of this declaration of trust as in
force at the time of such transactions.

      Section 17.-The Trustees may consult with any counsel, lawyer, valuer,
surveyor, engineer, broker, auctioneer, accountant or other expert, consultant
or person deemed by them competent, to be selected, employed, retained or
consulted by the Trustees at the expense of the Trust Property, whether
individuals, firms or corporations, and whether or not generally or specially
employed, retained or consulted, and any action taken by the Trustees in good
faith on the opinion or advice of, or information received from, any such
counsel, lawyer, valuer, surveyor, engineer, broker, auctioneer, accountant or
other expert, consultant or person deemed by them competent, shall be complete
and conclusive protection to the Trustees and each of them.

      Section 18.-Whenever in the administration of this trust the Trustees
shall deem it necessary or advisable that any matter be proved or established,
such matter (unless other evidence in respect thereof be herein specifically
prescribed) may be deemed by them and by each of them to be conclusively
proved and established by a certificate or instrument purporting to be signed
by the president or a vice-president or the treasurer or the secretary or any
assistant or temporary secretary of this trust and delivered to the Trustees,
or any of them, and such certificate or instrument shall be full warrant to
the Trustees and to each of them for any action taken or suffered by them or
by any of them under the provisions of this declaration of trust on the faith
thereof; but in their discretion the Trustees or any of them may accept other
evidence of such matter or may require or obtain from the officers of this
trust or from any other sources such further or additional evidence as to them
may seem reasonable. The Trustees may receive a certificate purporting to be
signed by the secretary or any assistant or temporary secretary as conclusive
evidence of the due adoption of any vote or resolution by the Shareholders and
conclusive evidence of the matters therein stated.

      Section 19.-The receipts of the Trustees or any of them for moneys or
things paid or delivered to them or him shall be effectual discharges to the
person, firm, association, trust or corporation paying or delivering the same
therefrom and from all liability to see to the application thereof. And no
purchaser or person, firm, association, trust or corporation dealing with the
Trustees, officers or agents of this trust shall be bound to ascertain or

<PAGE 18>


inquire whether any consent, resolution or other authorization of the Trustees
or Shareholders, as is herein required or provided for, has been obtained or
passed or as to the existence or occurrence of any event or purpose in or for
which a sale, lease, mortgage, pledge, or charge is herein authorized or
directed, or otherwise as to the purpose or regularity of any of the acts of
the Trustees, officers or agents of this trust purporting to be done in
pursuance of any of the trusts or powers herein contained, or as to the
regularity of the resignation or appointment of any Trustee, officer or agent;
and a transfer of the Trust Property, or any part thereof, executed by the
Trustee or Trustees in whom the same shall be vested at the time of any such
resignation or appointment (including any retiring Trustee who shall be
willing to act and shall act in executing such transfer but not otherwise
including any such retiring Trustee) for the purpose of vesting the same in
the Trustee or Trustees for the time being of these presents or providing
evidence of such vesting independently of such resignation or appointment,
shall, as to the property comprised in such transfer, be conclusive evidence
in favor of any such purchaser or other person, firm, association, trust or
corporation dealing with the Trustees of the validity of such transfer and of
the matters therein recited relating to such resignation or appointment or the
occasion thereof or the occasion of such transfer. And no purchaser or person,
firm, association, trust or corporation dealing with any Trustee purporting to
act during the absence or inability of any other Trustee shall be concerned to
ascertain to inquire whether an occasion exists upon which he is authorized so
to act.

      Section 20.-No corporation, trust, association or body politic shall be
affected by notice that any of its shares or bonds or other securities or
obligations are subject to any of the trusts of these presents or be bound to
see to the execution of any such trusts or to ascertain or inquire whether any
transfer of any such shares, bonds or securities or obligations by the
Trustees, officers or agents of this trust is authorized, notwithstanding such
authority may be disputed by some other person, firm, association, trust or
corporation.

            Interested Trustees, Officers, Agents and Shareholders.

      Section 21.-No Trustee, officer or agent of this trust shall be
disqualified merely by the holding of such office from acquiring shares of
stock in or bonds and other obligations of or from holding any office or place
or profit under this trust or any company in which this trust or the Trustees
shall be interested as stockholder or otherwise, or from dealing or
contracting with this trust or with the Trustees, officers or agents hereof or
with any such company as vendor, purchaser or otherwise, nor shall any such
dealing or contract or any dealing, contract or arrangement entered into by or
in behalf of this trust or of the Trustees, officer or agents hereof or by or
in behalf of any such company, in which dealing, contract or arrangement any
such Trustee, officer or agent may be in any way interested be voided, nor
shall any Trustee, officer or agent so contracting or being so interested be
liable to account to this trust or to the Trustees, officers, agents or
Shareholders hereof, or otherwise, for any profit or benefit arising from any
such office or place of profit or realized through any such dealing, contract
or arrangement, merely by reason of such Trustee, officer or agent, holding
that office or of any fiduciary relation thereby established. Such Trustee,
and such officer or agent shall, however, disclose the nature and extent of
his interest in advance of any such dealings. No Trustee shall vote or act by
written vote or resolution as a Trustee in respect of any dealing, contract or
arrangement in which he is so interested, and if he does so vote or act his
vote or action shall not be counted but shall not operate to render the
dealing, contract or arrangement voidable; and any dealing, contract or
arrangement shall be valid if approved or ratified by vote or in writing by
the holders of a majority of the Shares of this trust notwithstanding that any
or all of the Trustees, officers or agents may be interested therein and shall

<PAGE 19>


vote therefor.  A general notice that a Trustee, officer or agent is a member,
trustee, director, officer or stockholder of any specified company, and is to
be regarded as interested in all transactions with the company, shall be a
sufficient disclosure under this clause as regards such Trustee, officer or
agent, and under such general notice it shall not be necessary for such
Trustee, officer or agent, to give a special notice in regard to any
particular transaction with that company.

      No Shareholder shall be disqualified by his holding such shares, however
great in amount, from holding any office or place of profit hereunder or under
any company in which this trust or the Trustee shall be interested as
stockholder or otherwise, or from dealing or contracting with this trust or
with the Trustees, officers or agents hereof or with any such company as
vendor, purchaser or otherwise, nor shall any such dealing or contract or any
dealing, contract or arrangement entered into by or on behalf of this trust by
the Trustees, officers or agents hereof in which dealing, contract or
arrangement any such Shareholder shall be in any way interested be voided, nor
shall any such Shareholder so contracting or being so interested be liable to
account to this trust or to the Trustees, officers, agents or Shareholders
hereof, or otherwise, for any profit or benefit arising from any such office
or place of profit or realized through any such dealing, contract or
arrangement, by reason of such Shareholder holding such shares to any amount,
nor shall any fiduciary relation be deemed to be established by such
shareholding or any obligation imposed on such Shareholder to disclose the
fact of his interest.

      Unless the context otherwise requires, the word "company" and
the word "stockholder" as used in this Section shall refer to corporations,
trusts, partnerships and associations and stockholder, shareholder and member
thereof respectively.

      It is not intended by this Section to affect the liabilities of the
Trustees under Section 17 of Public Utility Holding Company Act of 1935.

                           Shares and Shareholders.

      Section 22.-The beneficial interest in this trust shall be and during
the continuance of this trust shall remain in the owners from time to time of
transferable shares of beneficial interest. The shares of beneficial interest
now authorized shall consist of fifty million (50,000,000) Common Shares
having a par value of two dollars ($2) per share and a class of Cumulative
Preferred Shares having a par value of one hundred dollars ($100) per share
(hereinafter called "Preferred Shares").

      Common Shares presently authorized but unissued may be issued by the
Trustees from time to time for such consideration and upon such terms and in
such manner as may be determined by vote at a meeting or by written consent of
the registered holders of a majority of the Common Shares at the time
outstanding, provided however that such presently authorized but unissued
Common Shares may be issued by the Trustees without such vote or written
consent upon such terms and in such manner as the Trustees may determine at
not less than the par value thereof, if issued:

      (A) To Provide the System with Funds 
          (1) To acquire additional stock of any subsidiary of the 
      System which is authorized for its proper corporate purposes;
          (2) To acquire common stock of any Massachusetts gas or
      electric company if as a result of such transaction the System
      will own 51% or more of such stock;
          (3) To acquire debt securities maturing more than one year
      from the date of issue thereof of any subsidiary of the System; or
          (4) To retire temporary indebtedness of the System incurred
      by it for the purchase of such stock or debt securities; or
          (5) To make temporary advances to any subsidiary of the
      System;. or

<PAGE 20>

      (B) In Exchange
          (1) For publicly held stock of any subsidiary of the System; or
          (2) For stock of any Massachusetts gas or electric company
      if as a result of such exchange the System will own 51% or more
      of such stock; or
      (C) To Provide Common Shares to Fund Long-Term Incentive Compensation
      Plans That may be Adopted from Time to Time and to fund compensation
      plans applicable to the Board of Trustees for services as a Trustee.

      The shares of beneficial interest now issued shall be fully paid and
non-assessable and all additional shares of beneficial interest hereafter
issued, upon receipt by the System of the consideration specified in the vote
or written consent authorizing the issue thereof, shall be fully paid and
non-assessable except to the extent otherwise specifically provided in the
certificates representing such shares.

      The conditions, preferences, voting powers, restrictions and
qualifications of the Preferred Shares and Common Shares shall be as follows:

      (a) The Preferred Shares shall be of the par value of $100 each and may
be issued in one or more series designated "Series________ ________%
Cumulative Preferred Shares" (inserting in each case a letter designation and
the dividend rate for the particular series). All Preferred Shares,
irrespective of series, shall constitute one and the same class of shares of
beneficial interest, shall be of equal rank and shall be identical in all
respects except that the shares of different series may vary, as determined by
vote at a meeting or by written consent of the registered holders of at least
two-thirds (2/3) of the Common Shares at the time outstanding and entitled to
vote, in the following respects:

            (1) the authorized number of shares of the particular series;
            (2) the amount payable on the particular series upon any
      liquidation, dissolution or winding up of the affairs of the
      System or distribution of capital; 
            (3) the terms of any conversion, participation or other
      special rights which may lawfully be provided for the particular
      series; and the shares of different series may vary, as determined
      by the Trustees, in the following respects:
            (1) the number of authorized shares of the particular series
      which shall be issued;
            (2) the annual dividend rate for the particular series;
            (3) the date from which dividends on shares of the particular
       series shall be cumulative;
            (4) the date for payment of the first dividend and each
      succeeding quarterly dividend payment date for the particular series;
            (5) the redemption price or prices for the particular series; 
            (6) the terms and amounts of any sinking fund or purchase fund
      which may be provided for the redemption or purchase of shares of
      the particular series.

      Whenever a vote of the Preferred Shares may be required for any purpose,
the shares voting, if of different series, shall be counted irrespective of
series and not by different series, except as otherwise provided by law or by
this trust. All shares of the same series shall be identical (except as to the
date from which dividends on shares issued at different times will be
cumulative) in all respects and each certificate representing Preferred Shares
shall state the designation of the series in which the shares represented by
such certificate are issued.

<PAGE 21>


      (b) Holders of the Preferred Shares shall be entitled to receive, when
and as declared by the Trustees out of funds legally available for the
declaration of dividends, cumulative dividends at the annual dividend rate per
share fixed for the particular series, and no more, payable in cash quarterly
in each year commencing on the date specified for the first dividend payment
as herein provided to shareholders of record on the respective record dates
fixed in advance for the purpose by the Trustees prior to the payment of each
such dividend, which record date for each dividend shall be the same for all
series, before any dividends on, or distribution of assets (by purchase of
shares or otherwise) to holders of, the Common Shares or any other shares
ranking junior to the Preferred Shares in respect of the payment of dividends
shall be declared or paid or set apart for payment. Dividends on Preferred
Shares shall be cumulative: (1) on shares of any series issued prior to the
first dividend payment date, from the date of issue of such shares or from
such other date as may be fixed by the Trustees prior to the issuance of such
shares; (2) on shares issued on or after such first dividend payment date,
from the quarterly dividend payment date next preceding the date of issue of
such shares or from the date of issue if that be a dividend payment date or
from such other date as may be fixed by the Trustees prior to the issuance of
such shares. No dividend shall be declared on any series of the Preferred
Shares or on any other class of Preferred Shares ranking on a parity with the
Preferred Shares in respect of the payment of dividends, for any quarterly
dividend period, unless there shall likewise be declared on all shares of all
series of the Preferred Shares and of any other such parity Preferred Shares
at the time outstanding, like proportionate dividends, ratably, in proportion
to the respective annual dividend rates fixed therefor, for the same quarterly
dividend period, to the extent that such shares are entitled to receive
dividends for such quarterly dividend period. Whenever dividends accrued on
all outstanding Preferred Shares to the last preceding quarterly dividend
payment date shall have been paid in full or declared and set apart for
payment, the Trustees may, without awaiting the expiration of the current
dividend period for the Preferred Shares, declare and pay dividends on the
Common Shares or any other shares ranking junior to the Preferred Shares in
respect of the payment of dividends.

      The expression "dividends accrued," as used in this Section, shall mean
the sum of amounts in respect of Preferred Shares then outstanding which, as
to each share, shall be an amount computed at the dividend rate per annum
fixed for the particular share from the date from which dividends on such
share become cumulative to the date with reference to which the expression is
used, irrespective of whether such amount or any part thereof shall have been
declared as dividends or there shall have existed any funds legally available
for the payment thereof, less the aggregate of all dividends paid or declared
and set apart for payment on such share.

      (c) The System shall have the right, at its option and by vote of the
Trustees, to redeem the Preferred Shares or any series thereof, as a whole at
any time, or in part from time to time, upon payment in cash of the redemption
price fixed for the shares of the particular series, together with dividends
accrued thereon to the redemption date. If less than all of any series of
Preferred Shares is to be redeemed at any time, the shares thereof to be
redeemed shall be selected by lot by the Trustees. If at any time the System
shall have failed to declare and pay or set apart for payment dividends in
full upon the Preferred Shares of all series for all past quarterly dividend
periods, thereafter and until all such dividends shall have been paid in full
or declared and set apart for payment, the System shall not redeem or
purchase, or permit any subsidiary to purchase, for any purpose, any Preferred
Shares of any series, unless all Preferred Shares of all series then
outstanding shall be redeemed. At its election, the System on or prior to the 

<PAGE 22>


redemption date, may deposit an amount equal to the aggregate redemption price
of the shares so to be redeemed, together with dividends accrued thereon to
the redemption date, with a bank or trust company having a capital and surplus
of not less than $2,000,000 and its principal office in Boston, Massachusetts,
designated by the Trustees, in trust for the account of the holders of the
shares so to be redeemed.

      Notice of any such redemption, and specifying the redemption date, shall
be mailed, postage prepaid, to each holder of record of the Preferred Shares
so to be redeemed, at his address as it appears on the books of the System,
not more than sixty (60) nor less than thirty (30) days prior to the
redemption date. Notice of redemption having been so given, the shares so to
be redeemed shall not be entitled to any dividends which may be declared after
the redemption date specified in such notice unless default be made in the
payment or deposit of the redemption price, together with dividends accrued
thereon to the redemption date, and on the redemption date, or on a date prior
thereto on which such deposit shall have been made, all rights of the
respective holders of such shares as shareholders of the System by reason of
the ownership of such shares shall cease, except the right to receive the
redemption price, together with dividends accrued thereon to the redemption
date, upon presentation and surrender of the certificates representing such
shares and such shares shall not be deemed to be outstanding after the
redemption date or the earlier date of such deposit. In case less than all the
shares represented by such certificates are to be redeemed, a new certificate
or certificates shall be issued representing the unredeemed shares. In case
the holders of Preferred Shares which shall have been redeemed shall not
within four (4) years after the redemption date claim any amount so 
deposited in trust for the redemption of such shares, such bank or trust
company shall, upon demand, pay over to the System any such unclaimed amount
so deposited with it, and shall thereupon be relieved of all responsibility in
respect thereof, and thereafter the holders of such shares shall look only to
the System for payment of the redemption price thereof, together with
dividends accrued thereon to the redemption date, but without interest. All
Preferred Shares so redeemed shall be cancelled and retired and no shares
shall be issued in place thereof. Subject to the provisions of paragraphs (c)
and (d) of this Section, the System may also from time to time repurchase any
Preferred Shares at not exceeding the redemption price.

      (d) In the event of any liquidation, dissolution or winding up (whether
voluntary or involuntary) of the affairs of the System or any distribution of
its capital, then the holders of each series of the Preferred Shares at the
time outstanding shall be entitled to be paid in cash the distributive amount
fixed for the particular series, together in each case with dividends accrued
thereon to the date fixed for payment of such distributive amounts, and no
more, before any distribution shall be made to the holders of Common Shares or
any other shares ranking junior to the Preferred Shares in respect of the
distribution of assets. No payments on account of such distributive amounts
shall be made to the holders of any series of the Preferred Shares or any
other Preferred Shares ranking on a parity with the Preferred Shares in
respect of the distribution of assets, unless there shall likewise be paid at
the same time to the holders of each other series of the Preferred Shares or
such parity shares like proportionate distributive amounts, ratably, in
proportion to the full distributive amounts to which they are respectively
entitled. After such payment to the holders of Preferred Shares or such parity
shares, the remaining assets and funds of the System shall be distributed
among the holders of the Common Shares. Consolidation or merger of the System
with or into any other corporation or corporations or association or
associations, or a sale or transfer of substantially all of the System's
assets as an entirety, shall not be deemed a liquidation, dissolution or
winding up of the affairs of the System within the meaning of this subsection
(d) if it does not effect any change in the preferences or rights of the
Preferred Shares as set forth herein which is substantially prejudicial to the
holders thereof.

<PAGE 23>


      (e) Except as expressly provided in this Section 22, holders of the
Preferred Shares shall have no right to be represented at or to receive notice
of meetings of the Shareholders and shall have no right to vote for the
election of Trustees or for any other purpose or on any other subject.

      However, whenever dividends accrued on any shares of any series of the
Preferred Shares at the time outstanding shall equal or exceed an amount
equivalent to six (6) full quarterly dividends thereon, holders of the
Preferred Shares shall have the right to be represented at and to receive
notice of any meeting of the Shareholders of the System held for the purpose
of electing Trustees and the exclusive right, voting separately as a class, to
elect two Trustees; and the remaining seven Trustees shall be elected by the
holders of the Common Shares.

      If and when all dividends in default on the Preferred Shares shall have
been paid in full or declared and set apart for payment, the holders of the
Preferred Shares shall again be excluded from the right to be represented at
and to receive notice of meetings of the Shareholders and from the right to
vote, except as by law or in this trust provided.

      Such dividends in default shall be declared and paid as soon as
reasonably practicable unless payment thereof is prevented by law or by the
provisions of any indenture or agreement to which the System is a party or
unless a majority of the Trustees elected otherwise than by holders of the
Preferred Shares shall determine that such payment is not in the best
interests of the System.

      The term of office of all persons who may be Trustees of the System at
the time when the right to vote for two Trustees shall accrue to holders of
the Preferred Shares as herein provided shall terminate upon the election of
new Trustees at a meeting of Shareholders which, if not otherwise called,
shall be called by the secretary of the System upon request of, or may be
called by, the holders of record of at least 10% of all Preferred Shares then
outstanding. The new Trustees so elected shall serve until the next annual
meeting of Shareholders subject to the following provision and until their
successors shall be chosen and qualified.

      When all dividends in default on the Preferred Shares shall have been
paid in full or declared and set apart for payment, each Trustee elected by
the holders of the Preferred Shares shall cease to hold office upon the
election of a successor or of a new Board of Trustees by the Shareholders
entitled to vote for Trustees at a meeting of Shareholders which, if not
otherwise called, shall be called by the secretary of the System upon request
of, or may be called by, one or more of the Trustees then in office.

      If the event calling for any election of Trustees as provided for herein
shall occur not more than sixty (60) and not less than forty (40) days before
the date for an annual meeting of the Shareholders, the election of Trustees
shall be held at such annual meeting, otherwise at a special meeting of the
Shareholders to be called for the purpose.

      Notice of every meeting of the Shareholders held for the election of
Trustees during a period when the holders of the Preferred Shares have the
right to vote for the election of two Trustees shall be given to the holders
of record of Preferred Shares and of Common Shares and shall state the purpose
of the meeting in respect of the election of Trustees representing the
different classes of shares.

<PAGE 24>


      At each such meeting a majority of the outstanding Preferred Shares
shall be required to constitute a quorum for the election of two Trustees by
the Preferred Shares, which two Trustees shall be elected by plurality vote of
the Preferred Shares represented at the meeting; and a majority of the
outstanding Common Shares shall be required to constitute a quorum for the
election of the remaining Trustees by the Common Shares, which Trustees shall
be elected by plurality vote of the Common Shares represented at the meeting.
In case of any vacancy in the office of a Trustee elected by holders of the
Preferred Shares, the remaining Trustee elected by holders of the Preferred
Shares may fill the vacancy by the election of a successor to hold office for
the unexpired term of such Trustee. So long as any of the Preferred Shares of
any series are outstanding, no amendment of this trust shall authorize the
removal of any Trustee elected by holders of the Preferred Shares unless
consented to by vote of the holders thereof.

      (f)   (1) So long as any of the Preferred Shares of any series are
outstanding, the System shall not, without the vote at a meeting called for
that purpose of holders of at least two-thirds of the total number of the
Preferred Shares of all series then outstanding:

            (a) change any of the provisions of the Preferred Shares,
      or of any series thereof, which would alter the preferences or
      rights of the holders thereof in any manner substantially
      pre-judicial to the holders thereof, except that if such change
      is prejudicial to the holders of one or more, but not all of
      such series, only the vote of the holders of two-thirds of the
      total number of shares of all series so affected and then
      outstanding shall be required; or

            (b) create any class of shares ranking prior to or on a
      parity with the Preferred Shares in respect of either the
      payment of dividends or the distribution of assets.

            (2) So long as any of the Preferred Shares of any series are
outstanding, the System shall not, without the vote at a meeting called for
that purpose of the holders of at least a majority of the total number of the
Preferred Shares of all series then outstanding:

            (a) issue any Preferred Shares in addition to the shares
      of the first series thereof or of any class of shares ranking
      prior to or on a parity with the Preferred Shares in respect
      of either the payment of dividends or the distribution of assets
      (except for the purpose of retiring shares ranking prior to the
      Preferred Shares or for the purpose of retiring Preferred Shares
      or shares ranking on a parity therewith if the shares issued
      are only shares thereof or on a parity therewith, provided the
      aggregate par or stated value of the shares to be retired) unless,
      after giving effect thereto,

                  (i) consolidated net income of the System and its
            subsidiaries for any period of twelve months within the
            next preceding fifteen months (after adding back interest
            charges on funded debt of the System deducted in the
            computation) shall have been at least equal to one and
            one-half (1/2) times the sum of the annual interest
            charges on funded debt of the System to be outstanding
            at the date of such issue plus the annual dividend
            requirements on the Preferred Shares and on any class
            of shares ranking prior to or on a parity with the
            Preferred Shares in respect of either the payment of
            dividends or the distribution of assets which is to be
            outstanding at the date of such issue, including the
            Shares to be issued but excluding any funded debt or
            Shares of such prior or parity shares to be retired in
            connection with such issue; and

<PAGE 25>

            
                  (ii) the aggregate amount of capital and paid-in
            premiums represented by the Common Shares and any other
            Shares ranking junior to the Preferred Shares in
            respect of either the payment of dividends or the
            distribution of assets plus the consolidated retained
            earnings of the System and its subsidiaries would be at
            least equal to the capital and paid-in premiums represented
            by the Preferred Shares and all other Shares ranking
            prior to or on a parity with the Preferred Shares in respect
            of either the payment of dividends or the distribution of
            assets to be outstanding after giving effect to such issue
            but excluding any such shares to be retired in connection
            therewith; 
or
            (b) merge into or consolidate with any other corporation or
      association unless the System shall itself be the successor; or
      otherwise sell or transfer its assets as, or substantially as, an
      entirety. The term "sell or transfer", as used therein, includes
      a lease or exchange, but does not include a mortgage or pledge.

      The term "funded debt", as used in this subsection (f), shall mean all
indebtedness, other than indebtedness incurred in the ordinary course of
business, maturing by its terms more than twelve months from the date on which
it was incurred, except that there shall not be included in funded debt any
indebtedness for the payment or redemption of which at maturity or on a
redemption date sums sufficient have been deposited in trust.

      The term "consolidated net income of the System and its subsidiaries" as
used in this subsection (f) shall mean for any particular period the net
income of the System and its subsidiaries on a consolidated basis for such
period determined in conformity with generally accepted accounting principles,
subject to any applicable requirements imposed by any regulatory body having
jurisdiction.

      The term "subsidiary" shall mean any corporation or trust of which the
System (either alone or through a subsidiary or subsidiaries or together with
a subsidiary or subsidiaries) owns a majority of the shares outstanding and
having power to vote on the election of at least a majority of the directors
in the case of a corporation, or at least a majority of the trustees in the
case of a trust.

            (g) Except as otherwise provided by law, no holder of Preferred
Shares shall be entitled as such as a matter of right to subscribe for or
purchase any part of any new or additional issue of Shares or warrants
carrying rights to Shares, or securities convertible into Shares, of any class
whatever, whether now or hereafter authorized, and whether issued for
cash, property, services or otherwise.

            (h) Preferred Shares when duly authorized may be issued for such
consideration as may be fixed from time to time by the Trustees and upon
receipt by the System of the consideration so fixed such Shares shall be
deemed to have been fully paid and shall not be liable to any further call or
assessment.

            (i) No Shareholder, Trustee, officer or agent of this trust
shall be held individually responsible for any action taken in good faith
though subsequently adjudged to be in violation of this Section.

            (j) Terms applicable to particular series of the Preferred
Shares:

<PAGE 26>


      The first series of the Preferred Shares shall be designated "Series A
____% Cumulative Preferred Shares" (inserting the annual dividend rate for the
particular series); the number of Shares of the first series which may be
issued shall be limited to 60,000 shares; the annual dividend rate per share,
the date from which such dividends shall be cumulative, the first dividend
payment date and each succeeding quarterly dividend payment date, and the
redemption prices shall be determined by vote of the Trustees; the amount
payable upon any liquidation, dissolution or winding up of the affairs of the
System or distribution of capital, if involuntary, shall be $100 per Share
and, if voluntary, shall be equal to the applicable redemption price per
Share, plus in each case dividends accrue to the date of distribution. 

      Common Shares in addition to the 50,000,000 Shares herein authorized may
be authorized from time to time by vote at a meeting or by the written consent
of the registered holders of a majority of the Common Shares at the time
outstanding and entitled to vote and may be issued from time to time by the
Trustees at not less than par for such consideration and upon such terms and
in such manner as may be determined by such vote or written consent or, if
authorized by such vote or written consent, upon such terms and in such manner
and for such consideration as may be determined by the Trustees. Such
additional Common Shares shall rank pari passu with the Common Shares now
authorized. Subject to the provisions of paragraphs (a) and (f) of this
Section, Shares in addition to Preferred Shares with any preference as to
dividends or in liquidation or otherwise over the Common Shares may be
authorized from time to time by vote at a meeting or by written consent of the
registered holders of at least two-thirds (2/3) of the Common Shares at the
time outstanding and entitled to vote and such additional Shares shall,
subject to the provisions of this Section 22, have such par value or be
without par value as may be determined by such vote or written consent, may be
issued by the Trustees for such consideration and upon such terms and in such
manner as may be determined by such vote or written consent, or if authorized
by such vote or written consent, upon such terms and in such manner and for
such consideration as the Trustees may determine, and shall have such
preferences and other rights as may be determined by such vote or written
consent, except for the following matters which may be determined by the
Trustees: 

            (1) the annual dividend rate for such Shares;
            (2) the date from which dividends on the Shares shall
      be cumulative;
            (3) the date for payment of the first dividend and each
      succeeding dividend payment date for the Shares;
            (4) the redemption price or prices for the Shares;
            (5) the terms and amount of any sinking fund or purchase
      fund which may be provided for the redemption or purchase of the Shares.

      No Common Shares (other than initially issued pursuant to the Plan
referred to in Section 5 (e) of this trust) shall be issued or sold for cash
unless the same shall first be offered pro rata to the holders of the Common
Shares at such price and on such terms and conditions and for such period as
may be determined by the Trustees unless the holders of two-thirds (2/3) of
the outstanding Common Shares, by vote at a meeting or in writing, shall
consent to some other disposition thereof except as hereinafter provided. Any
such Shares or securities so offered for subscription and not subscribed for
within the period so determined may be issued and sold to such persons,
whether Shareholders or not, as may be determined by the Trustees but if so
offered other than at a public auction or pursuant to competitive bidding,
such unsubscribed Shares or securities shall not be issued at a price less
than the price at which such Shares or securities were so offered to the
Common Shareholders. Such preemptive rights shall not apply (1) to the issue
of Shares of any class or other securities issued otherwise than for cash or

<PAGE 27>

(2) unless the Trustees shall prescribe otherwise, to the issue of Shares of
any class or other securities where such Shares or other securities are
publicly offered by competitive bidding or are sold to or through underwriters
or investment bankers for public sale; (3) to the issue of Common Shares where
such Shares are offered to holders of Common Shares pursuant to a plan whereby
such holders may purchase Common Shares by either investing cash dividends
from Common Shares of the System or making optional cash payments or both; or
(4) to the issue of Common Shares where such Shares are offered to the
Employees Savings Plan of Commonwealth Energy System and Subsidiary Companies
or the Tax Reduction Act of 1975 Employees Stock Ownership Plan of
Commonwealth Energy System and Subsidiary Companies; and except as herein
specifically provided no holder of Shares of this trust of any class shall
have any preemptive or preferential right of subscription to any Shares or
other securities of this trust. At the time of any issue of additional Common
Shares for cash, the Trustees may, in cases where such preemptive rights
apply, specify that holders of outstanding Common Shares shall not be entitled
to receive subscription rights for fractions of a Share, provided that if the
Trustees so specify each such holder who would otherwise be entitled to
receive fractional interests shall be entitled to receive as determined by the
Trustees, either (a) cash equal to the value, if any, which said rights would
have had, as determined by the Trustees, or (b) sufficient subscription rights
to enable said holder to subscribe for one whole Share.

      Section 23.-Shares in this trust acquired by this trust may be cancelled
and the number of Shares authorized be thereby reduced, or such Shares may be
held in the treasury or be reissued by the Trustees as the Trustees may from
time to time determine, provided, however, that before reissuing any Common
Shares, the same shall first be offered proportionally to holders of Common
Shares in the same manner as is provided in Section 22 hereof with respect to
additional Shares, unless the holders of a majority of the outstanding Common
Shares shall by vote at a meeting or in writing consent to some other
disposition; but such Shares while so held in the treasury shall not be
entitled to vote or give any consent hereunder or to receive any dividends and
shall not be deemed outstanding in computing proportions or percentages of
Shares or Shareholders hereunder or for any other purpose of this trust.

      Section 24.-A register or registers shall be kept by or on behalf of
this trust under the direction of the Trustees, which shall contain the names
and addresses of the Shareholders and the number and kind of Shares held by
them respectively and a record of all transfers thereof, which register or
registers shall be open to inspection by the holders of Common Shares to the
same extent as the stock and transfer books of Massachusetts business
corporations are open to the inspection of their stockholders. No Shareholder
shall be entitled to receive payment of any dividend declared, nor to have any
notice given to him as herein provided, until he has given his address to the
transfer agent, or such other officer or agent of this trust as shall keep the
said register, for entry thereon.

      Section 25.-The Trustees shall have power to employ in the city of
Boston and in any other cities the Trustees may designate a transfer agent or
transfer agents and a registrar or registrars and may employ as any such
transfer agent or registrar any corporation that is a Depositary hereunder.
The transfer agent or transfer agents shall keep the said registers and record
therein the transfers of any of the said Shares and countersign certificates
of Shares issued to the persons entitled to the same. The transfer agents and
registrars shall perform the duties usually performed by transfer agents and
registrars of certificates of stock in a corporation, except as modified by
the Trustees and the remuneration of such transfer agent or transfer agents
and such registrar or registrars shall be allowed as part of the expenses
incidental to the execution of this trust.

<PAGE 28>


      Section 26.-Every Shareholder shall be entitled to receive a certificate
in such form as the Trustees shall from time to time approve, specifying the
number and kind of Shares held by him, with such description, if any, as may
be necessary to distinguish them from other Shares to which different rights
are attached. Such certificates shall, unless otherwise determined by the
Trustees, be signed by the president or a vice-president and the secretary or
treasurer or an assistant secretary or assistant treasurer of this trust and
countersigned by the transfer agent, if any, and registered by a registrar, if
any, and a notation of such registration shall be made thereon. The seal of
the System and the signature or signatures of the president, vice-president,
secretary, treasurer, assistant secretary and/or assistant treasurer upon any
such certificate, may be made by engraving, lithographing or printing thereon
a facsimile of such seal or of such signature or signatures, in lieu of such
seal or actual signature, and such facsimile seal or signature or signatures
so engraved, lithographed or printed thereon shall have the same force and
effect as if such seal had been affixed thereto and such officer or officers
had actually signed the same. In accordance with the usual custom of
corporations having a transfer agent, signed certificates for Shares in blank
may be deposited with any transfer agent of this trust, to be used by the
transfer agent in accordance with authority conferred upon it as occasion may
require, and in so doing the signers of such certificates shall not be
responsible for any loss resulting therefrom.

      Section 27.-A new certificate may be issued by authority of the Trustees
to replace any certificate previously issued, on evidence satisfactory to the
Trustees that the said certificate previously issued has been worn out,
mutilated, lost or destroyed and on such terms, if any, as to indemnity and
otherwise, as the Trustees shall deem proper.

      Section 28.-Every transfer of any Shares (otherwise than by operation of
law) shall be by assignment in writing by the transferor or of his agent
thereunto duly authorized in writing, and upon delivery thereof to the
transfer agent of this trust (and if there be no transfer agent then to the
principal office of this trust) accompanied by the existing certificate for
such Shares and such evidence of the genuineness of such assignment,
authorization and other matters as may reasonably be required, shall be
recorded in the register, and a new certificate therefor shall be issued to
the transferee, and in case of a transfer of only a part of the Shares
mentioned in any certificate a new certificate for the residue thereof shall
be issued to the transferor. Until the transfer shall be so delivered and
recorded, the transferor shall be deemed to be the holder of the Share or
Shares comprised therein for all purposes hereof, and neither the Trustees nor
any transfer agent or registrar nor any officer or agent of this trust shall
be affected by any notice of the transfer.

      Section 29.-Any person becoming entitled to any Shares in consequence of
the death, bankruptcy or insolvency of any Shareholder, or otherwise, by
operation of law, shall be recorded in the register as the holder of the said
Shares, and receive a new certificate for the same, upon production of the
proper evidence thereof and delivery of the existing certificate to the
transfer agent of this trust and if there be no transfer agent then to the
principal office of the trust. But until such record is made the Shareholder
of record shall be deemed to be the holder of such Shares for all purposes
hereof, and neither the Trustees nor any transfer agent or registrar nor any
officer or agent of this trust shall be affected by any notice of such death,
bankruptcy or insolvency.

      Section 30.-Shares shall be personal property entitling the holders only
to the rights and interest in the Trust Property set forth in these presents,
and it is expressly declared and agreed that a trust and not a partnership is

<PAGE 29>


intended to be created by this instrument and that the Shareholders shall be
deemed to hold only the relationship of cestuis que trustent to the Trustees,
with only such rights as are conferred upon them as such cestuis que trustent
hereunder.

      Section 31.-Two or more persons holding any Share shall be joint tenants
of the entire interest therein, and no entry shall be made in the register or
in any certificate that any person is entitled to any future, limited or
contingent interest in any Share. But any person registered as a holder of any
Share may, subject to the provisions hereinafter contained, be described in
the register or in any certificate as a trustee of any kind, and any words may
be added to the description to identify the said trust.

      Section 32.-The Trustees shall not, nor shall the Shareholders, transfer
agent or other agent of this trust or of the Trustees be bound to take notice
or be affected by notice of any trust, whether express, implied or
constructive, or of any charge, pledge or equity to which any of the said
Shares or the interest of any of the Shareholders in this trust may be
subject, or to ascertain or inquire whether any sale or transfer of any such
Shares or interest by any such Shareholder or his personal representatives is
authorized by such trust, charge or equity, or to recognize any person as
having any interest therein, except the persons registered as such
Shareholders. And the receipt of the person in whose name any Share is
registered, or, if such Share is registered in the names of more than one
person, the receipt of any one of such persons or of the duly authorized agent
of any such person, shall be a sufficient discharge for all dividends and
other money and for all shares, bonds, obligations and other property,
payable, issuable or deliverable in respect of such Share and from all
liability to see to the application thereof.

                         Meetings of the Shareholders.

      Section 33.-An annual meeting of the Shareholders shall be held each
year at the principal office of the trust, in Cambridge, Massachusetts, or at
such other place either within or without the Commonwealth of Massachusetts as
shall be designated by the Trustees, on the first Tuesday of May of each such
year, or on such other date as the Trustees may fix (which date shall be not
more than 30 days before or after the first Tuesday of May), at which meeting
the Trustees shall submit to the Shareholders a financial report of the
affairs of the Trust for the past fiscal year and such other reports or
matters as the Trustees and officers of this trust may deem appropriate or
required. If such annual meeting is omitted on the day herein provided
therefor, a special meeting shall be held in lieu thereof and any business
transacted or election held at such special meeting shall have the same effect
as if transacted or held at the regular annual meeting.

      Section 34.-Subject to the provisions of Section 6 and Section 22 hereof
the Shareholders entitled to vote shall, at each annual meeting or special
meeting held in lieu thereof, elect three (3) Trustees to serve for the
ensuing three years and take such other further action as may properly come
before the meeting.

      Section 35.-The Trustees, president or treasurer of this trust may
whenever they think fit and the president or secretary of this trust, upon
written request of one-tenth (1/10) of all the Shares outstanding and entitled
to vote, shall call or direct any officer of this trust to call a special
meeting of the Shareholders to be held at the principal office of the trust or
at any place within or without the Commonwealth of Massachusetts as shall be
designated by the Trustees. Every such request shall express the purpose of
the meeting and shall be delivered at the principal office of the trust

<PAGE 30>

addressed to the president or secretary of the trust. In the event that the
president or secretary shall refuse or fail for fourteen (14) days after such
request has been delivered to call such special meeting, then the same may be
called by the person or persons signing such request. Notice of such special
meeting shall be given to all Shareholders entitled to vote thereat, not less
than thirty (30) days nor more than sixty (60) days (including Sundays and
holidays) prior to such meeting. The president, or in case of his absence or
unwillingness to preside, any vice-president shall be entitled to preside at
such meeting but in case neither the president nor any vice-president shall be
present or though present shall be unwilling to preside, a chairman shall be
chosen by the Shareholders represented at the meeting.

      Section 36.-At any special meeting no business or vote or resolution
shall be considered or adopted except such as is included in the purposes
specified in the notice of the meeting.

      Section 37.-A written or printed notice of each meeting of the
Shareholders, whether annual or special, specifying the time, place and
purposes thereof, shall be given as provided in Section 38 by the president or
secretary or any assistant secretary to each Shareholder entitled to vote
thereat not less than thirty (30) days nor more than sixty (60) days
(including Sundays and holidays) before such meeting.

      Section 38.-Every notice to any Shareholder required or provided for in
these presents may be given to him personally or by sending
it to him through the post office in a prepaid letter addressed to him at his
address specified in the Share register, and shall be deemed to have been
given at the time when it is so posted. But in respect of any Share held
jointly by several persons notice so given to any one of them shall be
sufficient notice to all of them. And any notice so sent to the registered
address of any Shareholder shall be deemed to have been duly sent in respect
of any such Share whether held by him solely or jointly with others,
notwithstanding he be then deceased or be bankrupt or insolvent, and whether
the Trustees or any person sending such notice have knowledge or not of his
death, bankruptcy or insolvency, until some other person or persons shall be
registered as holders. And the certificate of the person or persons giving
such notice shall be sufficient evidence thereof, and shall protect all
persons acting in good faith in reliance on such certificate.

      Section 39.-When any Share is held jointly by several persons any one of
them may vote at any meeting in person or by proxy in respect of such Share,
but if more than one of them shall be present at such meeting in person or by
proxy and such joint owners or their proxies so present disagree as to any
vote to be cast, such vote shall not be received in respect of such Share. If
the holder of any share is a minor or a person of unsound mind, or subject to
guardianship or to the legal control of any other person as regards the charge
or management of such Share, he may vote by his guardian or such other person
appointed or having such control, and such vote may be given in person or by
proxy.

      Section 40.-For the purposes of determining the Shareholders who are
entitled to vote or act at any meeting or any adjourned session thereof, the
Trustees may from time to time close the register and transfer books for such
period, not exceeding sixty (60) days, as the Trustees may determine; or,
without closing the said register or transfer books, the Trustees may fix a
time as of which the Shareholders entitled to vote or act at any meeting or
adjourned meetings held within sixty (60) days after the time so fixed shall
be determined.

      Section 41.-At all meetings every Shareholder shall, subject to the
provisions of Section 40, have one vote for every share held by him (except as
may be otherwise provided in case of shares issued with restricted or extended
voting rights) and may vote at any meeting or any adjournment or adjournments 

<PAGE 31>


thereof in person or by proxy in writing; and, except as otherwise provided
herein or in the rights, preferences and limitations relating to any class or
series of shares, the holders of a majority of all the shares issued and
outstanding and carrying the right to vote upon a question to be considered at
the meeting shall constitute a quorum for the consideration of such question.
If, at the expiration of half an hour from the time appointed for a meeting, a
quorum is not present, the Shareholders present in person or by proxy shall
constitute a quorum for the purpose of adjourning the meeting, either to a
later date or sine die but not for the transaction of any other business, and
the meeting may be held as adjourned without further notice.

                     Duration, Termination and Amendments.

      Section 42.-Unless sooner terminated as provided in Section 44, this
trust shall continue in such manner that the Trustees shall have all the
duties, powers, authorities and discretions expressed to be given to them by
these presents, and that no Shareholder shall be entitled to put an end to the
same or to require a division of the Trust Property or any part thereof until
January 2, 2050, or the expiration date of twenty (20) years from the death of
the last survivor of the following persons:

      Katherine Bilodeau, Kerri Bilodeau and Thomas H. Bilodeau III,
      children of Thomas H. Bilodeau, Jr. of Milton; Jill Heggie,
      daughter of James J. Heggie III of Milton; Maura J. Donlan,
      daughter of Michael F. Donlan of West Roxbury; Sarah M. Hundley
      and Laura S. Hundley, children of Franklin M. Hundley of Belmont;
      William F. Griffin III and Amy C. Griffin, children of William F.
      Griffin, Jr. of Melrose; Geoffrey May, Daniel May, John May and
      Eleanor May, children of Gerald V. May of Newton; Arthur M.
      Flaherty, Timothy E. Flaherty, Brian G. Flaherty, Shaun F.
      Flaherty and Mark J. Flaherty, children of Arthur F. Flaherty
      of North Scituate; Mary E. Landergan, Walter L. Landergan III
      and Thomas J. Landergan, children of Walter L. Landergan, Jr.
      of Lynnfield, all in the Commonwealth of Massachusetts,
      whichever of the said periods shall first expire, and at the
      expiration of the time so limited the said trust shall terminate.

      Section 43.-The death of a Shareholder or a Trustee during the
continuance of this trust shall not operate to terminate this trust, nor the
appointment of any officer or agent, nor shall it entitle the legal
representatives of any such Shareholder or Trustee to an accounting or to take
any action in the courts or otherwise.

      Section 44.-The Trustees may at any time alter, amend, add to or rescind
any of the terms, powers and provisions herein contained, if such alteration,
amendment, addition or rescission has been consented to by vote at a meeting
or by written consent obtained at a meeting or otherwise of the holders of a
majority of the outstanding Common Shares and of the holders of a majority (or
such greater or lesser proportion as the rights, preferences and limitations
relating to such class or series require or provide for) of the outstanding
Shares of each other class or series, if any, as shall, by the express terms
of the rights, preferences and privileges thereof, be entitled to vote thereon
or consent thereto. Such alteration, amendment, addition or rescission or any
termination of this trust shall, however, become effective only upon the
filing, at the principal office of the Depositary where this Declaration of
Trust is filed or at the principal office of this trust if there be no such
Depositary, of a certificate signed by a majority of the Trustees, setting
forth the said alteration, amendment, addition or rescission or termination
and that the Shareholders have consented thereto as required by this

<PAGE 32>


Declaration of Trust. The Trustees shall cause counterparts of said
certificate to be recorded in the various registries of deeds, if any, where
this Declaration of Trust is then recorded, and shall cause counterparts or
copies of said certificate to be recorded or filed in such other places as may
be required by law.

      Notwithstanding the foregoing, no provision of this trust requiring the
vote of the registered holders of a specified proportion greater than a
majority of the Shares entitled to vote, may be altered, amended or rescinded
except by the affirmative vote or written consent of the holders of not less
than such specified proportion of such Shares.

      Section 45.-Upon the termination of this trust by said limitation or
under the provisions herein contained the Trustees shall, upon such terms as
shall be determined by the Trustees, sell, and convert into money or into
shares, bonds and other securities or obligations, whether of the purchaser or
otherwise, the whole or any part of the Trust Property and, after paying or
otherwise providing for the payment of all of the obligations and liabilities
of the trust, shall apportion the net proceeds thereof and any property
forming part of the Trust Property excepted from such sale among all the
Shareholders in accordance with their respective rights ratably according to
the number and kind of Shares held by them respectively. And in making any
sale under these provisions the Trustees shall have power to sell by public
auction or private contract and to buy in or rescind or vary any contract of
sale and to resell, without being answerable for loss, and for the said
purposes to execute or cause to be executed all proper deeds and instruments
and to do all proper things. But the Trustees may, after the distribution of
the full amounts of money, if any, due upon liquidation or termination on the
preferred shares of any class or series which may be outstanding, divide the
whole or any part of the remaining Trust Property in its actual state of
investment among the Shareholders in accordance with their respective rights
ratably according to the number and kind of Shares held by them respectively,
and for such purposes the Trustees shall have power to determine the values of
the property comprising said remaining Trust Property.

      Section 46.-This declaration of trust may be executed in any number of
counterparts, each of which shall be deemed an original, but all such
counterparts taken together shall constitute but one and the same instrument.

      In Witness Whereof the said original Trustees have hereunto set their
hands and seals the day and year first above written.

I, Michael P. Sullivan hereby certify that I am Secretary of Commonwealth
Energy System, a Massachusetts Trust, established under a Declaration of Trust
dated December 31, 1926, and that the foregoing is a true composite copy of
