CONNECTICUT NATURAL GAS CORPORATION
                              EMPLOYEE SAVINGS PLAN

                                 TRUST AGREEMENT


             This Trust Agreement is made as of this 1st day of January, 1993,
   by and between CONNECTICUT NATURAL GAS CORPORATION, a corporation created
   under the laws of the state of Connecticut having its principal office in
   Hartford, Connecticut (the "Company") and PUTNAM FIDUCIARY TRUST COMPANY, a
   Massachusetts trust company having its principal office in Boston,
   Massachusetts (the "Trustee").

                                   WITNESSETH:

          1. ESTABLISHMENT OF PLAN.  The Connecticut Natural Gas Corporation
             Employee Savings Plan (the "Plan") has been adopted by the Company
             and is intended to satisfy those provisions of the Internal
             Revenue Code of 1986, as the same may be amended from time to time
             (the "Code"), relating to qualified employer plans.

          2. CREATION OF TRUST.  There is hereby established a trust which
             shall be known as the "Connecticut Natural Gas Corporation
             Employee Savings Plan Trust."  All money and such property as
             shall be acceptable to the Trustee as shall from time to time be
             paid or delivered to the Trustee in its capacity as such, all
             investments made therewith and proceeds thereof and all earnings
             and profits thereon, less the payments which at the time of
             reference shall have been made by the Trustee, as authorized
             herein, are referred to herein as the "Trust."  The Trustee hereby
             accepts the Trust created hereunder and agrees to perform the
             provisions of this Agreement on its part to be performed.  Subject
             to the conditions and limitations set forth herein, the Trustee
             shall be responsible for the property received by it as Trustee,
             but shall not be responsible for the administration of the Plan or
             for those assets of the Plan which have not been delivered to and
             accepted by the Trustee.  The Trustee shall not have any authority
             or obligation to determine the adequacy of or to enforce the
             collection from the Company of any contribution to the Trust.

             The establishment of the Trust created by this Agreement shall not
             be considered as giving any Plan member or any other person any
             legal or equitable rights as against the Company or the Trustee or
             the property, whether corpus or income, of the Trust unless such
             right is specifically provided for in this Agreement, the Plan, or
             by law, nor shall it be considered as giving any Plan member or
             other employee the right to continue in the service of the
             Company.

          3. PURPOSES.  The Plan and the Trust have been established for the
             exclusive benefit of the eligible employees and their
             beneficiaries.  So far as possible this Agreement shall be
             interpreted in a manner consistent with the intention of the
             Company that the Trust satisfy those provisions of the Code
             relating to qualified employees' trusts exempt from taxation under
             Section 501(a) of the Code.  It is specifically intended that the
             Company shall have sole responsibility for maintaining the tax-
             qualified status of the Plan and Trust.  No property of the Trust
             or contributions made by the Company pursuant to the terms of the
             Plan shall revert to the Company or be used for any purpose other
             than providing benefits to eligible employees or their
             beneficiaries and defraying the expenses of the Plan and the
             Trust, except that:

             (a)  Any amount contributed under the Plan by the Company by a
                  mistake of fact as determined by the Company shall be
                  returned to the Company, upon its request, within one year
                  after its payment to the Trust.

             (b)  Amounts contributed under the Plan by the Company are
                  contributed on the condition of their deductibility under
                  Section 404 of the Code, and upon the Company's written
                  notice to the Trustee, such contributions shall be returned
                  to the Company within one year after the Internal Revenue
                  Service disallows the deduction in writing.

             (c)  Earnings attributable to contributions returnable under
                  paragraph (a) or (b) shall not be returned to the Company,
                  and any losses attributable to those contributions shall
                  reduce the amount returned.

          4. MANAGEMENT OF TRUST.  It shall be the duty of the Trustee:

             (a)  to hold and, subject to the provisions of this Agreement, to
                  invest and to reinvest the assets of the Trust, and

             (b)  to make payments therefrom in accordance with the written
                  directions of the Plan Administrator (the "Administrator")
                  designated pursuant to the Plan to administer the Plan or its
                  delegate.  The Administrator shall be the "plan
                  administrator" of the Plan as defined in Section 3(16)(A) of
                  the Employee Retirement Income Security Act of 1974
                  ("ERISA"), and a "named fiduciary" within the meaning of
                  Section 402(a) of ERISA.  Any action to be taken under the
                  terms of this Agreement by the Administrator may be taken by
                  the Plan's Administrative Committee, as a named fiduciary
                  under the Plan, or its delegate in accordance with the Plan
                  and the provisions of ERISA.  The Administrator may direct
                  payments to be made from the Trust to any person, including
                  any member of the Administrator, or to the Company, or to any
                  paying agent designated by the Administrator, and in such
                  amounts as the Administrator may direct.  Each such direction
                  of the Administrator shall be in writing and shall be deemed
                  to include a certification that any payment directed thereby
                  is one which the Administrator is authorized to direct, and
                  the Trustee may conclusively rely on such certification
                  without further investigation.  Payments by the Trustee may
                  be made by its check to the order of the payee and mailed to
                  the payee at the address last furnished to the Trustee by the
                  Administrator or by the payee, or if no such address has been
                  furnished, to the payee in care of the Company.  The Trustee
                  shall make disbursements in the amounts and in the manner
                  that the Administrator directs from time to time in writing. 
                  The Trustee shall have no responsibility to ascertain any
                  direction's compliance with the terms of the Plan or of any
                  applicable law or the direction's effect for tax purposes or
                  otherwise; nor shall the Trustee have any responsibility to
                  see to the application of any disbursement.  The Trustee
                  shall not be required to make any disbursement in excess of
                  the net realizable value of the assets of the Trust at the
                  time of the disbursement.  The Trustee shall not be required
                  to make any disbursement in cash unless the Administrator has
                  provided a written direction as to the assets to be converted
                  to cash for the purpose of making the disbursement.

                                      - 2 -
          5. INVESTMENTS.  Except as otherwise provided in Sections 6, 7 and 8
             below, the Trustee shall invest and reinvest the assets of the
             Trust and keep the same invested, without distinction between
             principal and income, in stocks, bonds, stock options, option
             contracts of any type, contracts for the immediate or future
             delivery of financial instruments and other property, or other
             securities or certificates of participation or shares of any
             mutual investment company, trust or fund (including mutual funds
             which are sponsored, underwritten or managed by affiliates of the
             Trustee), or deposits in the Trustee which bear a reasonable rate
             of interest, or annuity or investment contracts issued by an
             insurance company, or other property of any kind, real or
             personal, tangible or intangible, as it may deem advisable,
             provided that the Trustee may hold assets of the Trust uninvested
             from time to time if and to the extent that it may deem such to be
             in the best interests of the Trust.  Notwithstanding the
             foregoing, unless an investment manager is appointed in accordance
             with Section 8, or the service agreement between the Company and
             the Trustee or its affiliate otherwise specifically provides, all
             of the assets of the Trust shall be invested as the Administrator
             directs in investment products sponsored, underwritten or managed
             by affiliates of the Trustee, loans to Plan members (if the Plan
             permits loans) or securities issued by the Company satisfying the
             conditions of Section 6.

          6. INVESTMENT FUNDS.  The Administrator from time to time may direct
             the Trustee to establish one or more separate investment accounts
             within the Trust, each such separate account being hereinafter
             referred to as an "Investment Fund."  The Trustee shall transfer
             to each such Investment Fund such portion of the assets of the
             Trust as the Administrator or Plan members direct in accordance
             with the specific provisions of the Plan and in the manner
             provided in the service agreement between the Company and the
             Trustee or its affiliate.  The Trustee shall invest and reinvest
             the assets which have been allocated to an Investment Fund in
             accordance with the investment guidelines, objectives and
             restrictions which have been established by the Administrator for
             that Investment Fund and, in the case of an Investment Fund for
             which an Investment Manager has been appointed, the specific
             investment directions of such Investment Manager.  If, and to the
             extent, specifically authorized by the Plan, and provided in the
             service agreement between the Company and the Trustee or its
             affiliate, the Administrator may direct the Trustee to establish
             an Investment Fund all of the assets of which shall be invested in
             shares of stock of the Company, subject to the terms and
             conditions of Section 7.

             The Trustee shall be under no duty to question or review the
             investment guidelines, objectives and restrictions established, or
             the specific investment directions given, by the Administrator or
             the Plan members for any Investment Fund or to make suggestions to
             the Administrator in connection therewith.  The Trustee shall not
             be liable for any loss, or by reason of any breach, which arises
             from the Administrator's or Plan members' exercise or non-exercise
             of rights under this Section 6, or from any direction of the
             Administrator or Plan members unless it is clear on the face of
             the direction that the actions to be taken under the direction are
             prohibited by the fiduciary duty rules of Section 404(a) of ERISA. 
             The Trustee shall incur no liability on account of investing the
             assets of the Trust in accordance with investment elections of the
             Administrator or Plan members so delivered to the Trustee.

                                      - 3 -
             All interest, dividends and other income received with respect to,
             and any proceeds received from the sale or other disposition of,
             securities or other property held in an Investment Fund shall be
             credited to and reinvested in such Investment Fund, and all
             expenses of the Trust which are properly allocable to a particular
             Investment Fund shall be so allocated and charged.  The
             Administrator may at any time direct the Trustee to eliminate any
             Investment Fund or Funds, and the Trustee shall thereupon dispose
             of the assets of such Investment Fund and reinvest the proceeds
             thereof in accordance with the directions of the Administrator.

             Pending investment in the Investment Funds in accordance with the
             directions of the Administrator or the Plan members, the Trustee
             shall invest assets of the Trust as provided in the service
             agreement between the Company and the Trustee or its affiliate, or
             if there is no such provision, the Trustee may invest assets of
             the Trust, in whole or in part, at any time or from time to time,
             in interest-bearing accounts or certificates of deposit (including
             deposits in the Trustee which bear a reasonable interest rate),
             treasury bills, commercial paper, money market funds (including
             any such fund sponsored, underwritten or managed by one of its
             affiliates), short-term investment funds or other short-term
             obligations in its discretion, and the investment return thereon
             shall be allocated among the Plan members whose assets have been
             so invested and added to their respective investments in the
             Investment Funds.

          7. TRUST INVESTMENTS IN COMPANY STOCK.  Trust investments pursuant to
             this Section 7 shall be made only in securities constituting
             "qualifying employer securities" within the meaning of Section
             407(d)(5) of ERISA.  Trust investments in such securities of the
             Company ("Company Stock") shall be subject to the following terms
             and conditions:

             (a)  ACQUISITION LIMIT.  Pursuant to the Plan, the Trust may be
                  invested in Company Stock to the extent necessary to comply
                  with investment directions under Section 6 of this Agreement.

             (b)  FIDUCIARY DUTIES OF NAMED FIDUCIARIES.  The Administrator as
                  named fiduciary shall continually monitor the suitability of
                  acquiring and holding Company Stock under the fiduciary duty
                  rules of Section 404(a)(1) of ERISA (as modified by Section
                  404(a)(2) of ERISA).  The Trustee shall not be liable for any
                  loss, or by reason of any breach, which arises from the
                  direction of the Administrator with respect to the
                  acquisition and holding of Company Stock, unless it is clear
                  on the face of the direction that the actions to be taken
                  under the direction would be prohibited under ERISA.  The
                  Company hereby appoints as named fiduciaries, solely with
                  respect to the voting of Company Stock held in the Trust and
                  the tender or retention of such Company Stock in response to
                  a tender offer, the eligible employees who are Plan members
                  in the Plan at the time in question.  The Company shall be
                  responsible for determining whether, under the circumstances
                  prevailing at a given time, its fiduciary duty to Plan
                  members and beneficiaries under the Plan and ERISA requires
                  that the Company follow the advice of independent counsel as
                  to the voting and tender or retention of Company Stock.




                                      - 4 -
             (c)  EXECUTION OF PURCHASES AND SALES.  To implement the
                  investment of new contributions, the Trustee shall purchase
                  Company Stock on the open market as soon as practicable
                  following the date on which the Trustee receives from the
                  Company in good order all information and documentation
                  necessary to effect the purchase.  Redemptions and exchanges
                  of Company Stock shall be netted against purchases made in
                  accordance with the preceding sentence, and to the extent
                  necessary after such netting, the Trustee shall, as soon as
                  practicable following the date of such purchases, purchase or
                  sell Company Stock on the open market to accomplish such
                  redemptions and exchanges.

                  The Trustee may purchase or sell Company Stock from or to the
                  Company if the purchase or sale is for no more than adequate
                  consideration (within the meaning of Section 3(18) of ERISA)
                  and no commission is charged.  To the extent that Company
                  contributions under the Plan are to be invested in Company
                  Stock, the Company may transfer Company Stock to the Trust in
                  lieu of cash.  The number of shares so transferred shall be
                  determined by dividing the amount of the contribution by the
                  closing price of Company Stock on any national securities
                  exchange on the trading day immediately preceding the date as
                  of which the contribution is made.

                  The Trustee and the Company may, in an appendix to this
                  Section 7, agree upon such prescribed dates for purchases and
                  sales of Company Stock and such rules and conventions in
                  connection with such purchases and sales as they may find
                  mutually acceptable.

             (d)  SECURITIES LAW REPORTS.  The Administrator shall be
                  responsible for filing all reports required under federal or
                  state securities laws with respect to the Trust's ownership
                  of Company Stock, including, without limitation, any reports
                  required under Section 13 or 16 of the Securities Exchange
                  Act of 1934, and shall immediately notify the Trustee in
                  writing of any requirement to stop purchases or sales of
                  Company Stock pending the filing of any report.  The Trustee
                  shall provide to the Administrator such information on the
                  Trust's ownership of Company Stock as the Administrator may
                  reasonably request in order to comply with federal or state
                  securities laws.

             (e)  VOTING.  Notwithstanding any other provision of this
                  Agreement, the provisions of this Section 7(e) shall govern
                  the voting of Company Stock.  When the issuer of Company
                  Stock files preliminary proxy solicitation materials with the
                  Securities and Exchange Commission, the Company shall cause a
                  copy of all the materials to be simultaneously sent to the
                  Trustee, and the Trustee shall prepare a voting instruction
                  form based upon these materials.  At the time of mailing of
                  notice of each annual or special stockholders' meeting of the
                  issuer of Company Stock, the Company shall cause a copy of
                  the notice and all proxy solicitation materials to be sent to
                  each Plan member, together with the foregoing voting
                  instruction form to be returned to the Trustee or its
                  designee.  The form shall show the number of full and
                  fractional shares of Company Stock credited to the Plan
                  member's accounts, whether or not vested.  For purposes of
                  this Section 7(e), the number of shares of Company Stock

                                      - 5 -
                  deemed credited to a Plan member's accounts shall be
                  determined as of the last preceding valuation date for which
                  an allocation has been completed and Company Stock has
                  actually been credited to Plan members' accounts.  The
                  Company shall provide the Trustee with a copy of any
                  materials provided to Plan members and shall certify to the
                  Trustee that the materials have been mailed or otherwise sent
                  to Plan members.

                  Each Plan member shall have the right to direct the Trustee
                  as to the manner in which to vote that number of shares of
                  Company Stock credited to his accounts.  Such directions
                  shall be communicated in writing or by facsimile or similar
                  means and shall be held in confidence by the Trustee and not
                  divulged to the Company, or any officer or employee thereof,
                  or any other person.  Upon its receipt of directions, the
                  Trustee shall vote the shares of Company Stock credited to
                  the Plan member's account as directed by the Plan member.

                  The Trustee shall vote those shares of Company Stock not
                  credited to Plan members' accounts, and those shares of
                  Company Stock credited to the accounts of Plan members for
                  which no voting directions are received, as directed by the
                  Compensation and Fringe Benefits Committee of the Board of
                  Directors of the Company, which the Company hereby appoints
                  as a named fiduciary solely with respect to the voting of
                  such shares of Company Stock. 

             (f)  TENDER OFFERS.  Upon commencement of a tender offer for any
                  Company Stock, the Company shall notify each Plan member, and
                  use its best efforts to timely distribute or cause to be
                  distributed to Plan members the same information that is
                  distributed to shareholders of the issuer of Company Stock in
                  connection with the tender offer, and after consulting with
                  the Trustee shall provide at the Company's expense a means by
                  which Plan members may direct the Trustee whether or not to
                  tender the Company Stock credited to their accounts (whether
                  or not vested).  The Company shall provide to the Trustee a
                  copy of any material provided to Plan members and shall
                  certify to the Trustee that the materials have been mailed or
                  otherwise sent to Plan members.

                  Each Plan member shall have the right to direct the Trustee
                  to tender or not to tender some or all of the shares of
                  Company Stock credited to his accounts.  Directions from a
                  Plan member to the Trustee concerning the tender of Company
                  Stock shall be communicated in writing or by facsimile or
                  such similar means as is agreed upon by the Trustee and the
                  Company.  The Trustee shall tender or not tender shares of
                  Company Stock as directed by the Plan member.  The Trustee
                  shall not tender shares of Company Stock credited to a Plan
                  member's accounts for which it has received no directions
                  from the Plan members.

                  The Trustee shall tender that number of shares of Company
                  Stock not credited to Plan members' accounts determined by
                  multiplying the total number of such shares by a fraction, of
                  which the numerator is the number of shares of Company Stock
                  credited to Plan members' accounts for which the Trustee has
                  received directions from Plan members to tender (which
                  directions have not been withdrawn as of the date of this

                                      - 6 -
                  determination), and of which the denominator is the total
                  number of shares of Company Stock credited to Plan members'
                  accounts.

                  A Plan member who has directed the Trustee to tender some or
                  all of the shares of Company Stock credited to his accounts
                  may, at any time before the tender offer withdrawal date,
                  direct the Trustee to withdraw some or all of the tendered
                  shares, and the Trustee shall withdraw the directed number of
                  shares from the tender offer before the tender offer
                  withdrawal deadline.  A Plan member shall not be limited as
                  to the number of directions to tender or withdraw that he may
                  give to the Trustee.

                  A direction by a Plan member to the Trustee to tender shares
                  of Company Stock credited to his accounts shall not be
                  considered a written election under the Plan by the Plan
                  member to withdraw or to have distributed to him any or all
                  of such shares.  The Trustee shall credit to each account of
                  the Plan member from which the tendered shares were taken the
                  proceeds received by the Trustee in exchange for the shares
                  of Company Stock tendered from that account.  Pending receipt
                  of directions through the Administrator from the Plan member
                  as to the investment of the proceeds of the tendered shares,
                  the Trustee shall invest the proceeds as the Administrator
                  shall direct.

             (g)  GENERAL.  With respect to all rights other than the right to
                  vote, the right to tender, and the right to withdraw shares
                  previously tendered, the Trustee shall follow the directions
                  of the Plan member as to Company Stock credited to his
                  accounts, and if no such directions are received, the
                  directions of the Administrator.  The Trustee shall have no
                  duty to solicit directions from Plan members.  With respect
                  to all rights other than the right to vote and the right to
                  tender, in the case of Company Stock not credited to Plan
                  members' accounts, the Trustee shall follow the directions of
                  the Administrator.  All provisions of this Section 7 shall
                  apply to any securities received as a result of a conversion
                  of Company Stock.

          8. APPOINTMENT OF INVESTMENT MANAGERS.  The Administrator from time
             to time may appoint one or more Investment Managers (as that term
             is defined in Section 3(38) of ERISA) to manage (including the
             power to acquire and dispose of) all or any portion or portions of
             the Trust.  The Administrator may enter into such agreements
             setting forth the terms and conditions of any such appointment as
             it determines to be appropriate.  The Administrator shall retain
             the right to remove and discharge any Investment Manager.  The
             compensation of such Investment Managers shall be an expense
             payable in accordance with Section 14.  The Administrator shall
             notify the Trustee of the appointment of any Investment Manager by
             delivering to the Trustee an executed copy of the agreement under
             which such Investment Manager was appointed together with a
             written acknowledgment by such Investment Manager that it is 

             (a)  a fiduciary with respect to the Plan,

             (b)  bonded as required by ERISA, and



                                      - 7 -
             (c)  either

                  (i)      registered as an investment advisor under the
                           Investment Advisers Act of 1940, or

                  (ii)     a bank as defined in said Act, or

                  (iii)    an insurance company qualified to perform investment
                           management services under the laws of more than one
                           state of the United States.

             The Trustee shall be entitled to rely upon such notice until such
             time as the Administrator shall notify and direct the Trustee in
             writing that another Investment Manager has been appointed in the
             place and stead of the first-named Investment Manager, or in the
             alternative, that the Investment Manager has been removed.  In
             each case where an Investment Manager is appointed, the
             Administrator shall determine the assets of the Trust to be
             allocated to the Investment Manager from time to time and shall
             issue appropriate instructions to the Trustee with respect
             thereto.  The Trustee shall carry out the written instructions of
             any Investment Manager with respect to the management and
             investment of the assets then under control of such Investment
             Manager and shall not incur any liability on account of its
             compliance with such instructions.  Purchase and sale orders may
             be placed without the intervention of the Trustee and, in such
             event, the Trustee's sole obligation shall be to make payment for
             purchased securities and deliver those that have been sold when
             advised of the transaction.  The Trustee shall not incur any
             liability on account of its failure to exercise any of the powers
             delegated to any Investment Manager because of the failure of such
             Investment Manager to give instructions for the management of the
             assets under the control of such Investment Manager.  The Trustee
             shall be under no duty to question any Investment Manager, nor to
             review any securities or other property acquired or retained at
             the direction of any Investment Manager, nor to make any
             suggestions to any Investment Manager in connection therewith. 
             The Trustee shall have no obligation to vote upon any securities
             over which the Investment Manager has investment management
             control unless the Trustee is instructed in writing by the
             Investment Manager as to the voting of such securities within a
             reasonable time before the time for voting thereof expires.

             Each Investment Manager shall have the authority to exercise all
             of the powers of the Trustee hereunder with respect to assets
             under its control but only to the extent that such powers relate
             to the investment of such assets.

          9. INSURANCE CONTRACTS.  If provided in the service agreement between
             the Company and the Trustee or its affiliate, the Administrator
             may direct the Trustee to receive and hold or apply assets of the
             Trust to the purchase of individual or group insurance or annuity
             contracts issued by any insurance company and in a form approved
             by the Administrator, including contracts under which the contract
             holder is granted options to purchase insurance or annuity
             benefits.  The Trustee shall be under no duty to question any
             direction of the Administrator or to review the form of any such
             policies or contracts or of the selection of the issuer thereof,
             or to make suggestions to the Administrator with respect to the
             form of such policies or contracts or to the issuer thereof.  The
             Administrator may direct the Trustee to exercise or may exercise

                                      - 8 -
             directly the powers of the contract holder under any such policies
             or contracts, and the Trustee shall exercise such powers only upon
             the direction of the Administrator.  The Trustee shall be fully
             protected in acting in accordance with written directions of the
             Administrator, and shall be under no liability for any loss of any
             kind which may result by reason of any action taken or omitted by
             it in accordance with any direction of the Administrator, or by
             reason of inaction in the absence of written directions from the
             Administrator.  In the event that the Administrator directs that
             any monies or property be paid or delivered to the contract holder
             other than for the benefit of specific individual beneficiaries,
             the Trustee agrees to accept such monies or property as assets of
             the Trust subject to all the terms hereof.

          10.     POWERS OF TRUSTEE.  Subject to the foregoing provisions and
                  limitations, the Trustee is authorized and empowered:

             (a)  to sell at public auction or by private contract, redeem,
                  convey, transfer, exchange, pledge, or otherwise realize
                  upon, any securities, investments or other property forming a
                  part of the Trust, and for such purposes may execute such
                  instruments and writings and do such things as it shall deem
                  proper;

             (b)  to keep any or all securities or other property in the name
                  of some other person, nominee, firm or corporation or in its
                  own name without disclosing its fiduciary capacity, but the
                  books and records of the Trustee shall at all times show that
                  all such securities and other property are part of the Trust;

             (c)  except as otherwise provided in Sections 7 and 8, to the
                  extent that the Trustee receives direction from the
                  Administrator or the Plan members, as the case may be, to
                  vote upon any stock, bonds or other securities of any
                  corporation, association or trust at any time comprising the
                  Trust, or otherwise consent to or request any action on the
                  part of such corporation, association or trust, and to give
                  general or special proxies or powers of attorney, with or
                  without power of substitution, and to exercise any conversion
                  privileges, subscription rights or other options, to
                  participate in reorganizations, recapitalizations,
                  consolidations, mergers and similar transactions with respect
                  to such securities; to deposit such stocks or other
                  securities in any voting trust, or with any protective or
                  like committee, or with a trustee, or with depositories
                  designated thereby; and generally to exercise any of the
                  powers of an owner with respect to stocks or other securities
                  or property comprising the Trust which the Trustee deems to
                  be for the best interests of the Trust.  The Trustee will not
                  vote such stock or other securities as to which it receives
                  no written directions;

             (d)  when instructed or directed by the Administrator, to borrow
                  money for the purposes of this Trust in such amounts and upon
                  such terms and conditions as the Administrator, in its
                  discretion, may approve, and for any amount so borrowed to
                  issue the promissory note of the Trustee and to secure the
                  repayment thereof by pledge, mortgage, or hypothecation of 




                                      - 9 -
                  all or any part of the property of the Trust, and no person
                  loaning money to the Trustee shall be bound to see to the
                  application of the money loaned or to inquire into the
                  validity of any such borrowing;

             (e)  to make, execute, acknowledge and deliver any and all
                  instruments that it shall deem necessary or appropriate to
                  carry out the powers herein granted;

             (f)  to manage, administer, operate, lease for any number of
                  years, develop, improve, repair, alter, demolish, mortgage,
                  pledge, grant options with respect to, or otherwise deal with
                  any real property or interest therein at any time held by it,
                  and to cause to be formed a corporation or trust to hold
                  title to any such real property with the aforesaid powers,
                  all upon such terms and conditions as may be deemed
                  advisable;

             (g)  to renew or extend or participate in the renewal or extension
                  of any mortgage, upon such terms as may be deemed advisable,
                  and to agree to a reduction in the rate of interest on any
                  mortgage or to any other modification or change in the terms
                  of any mortgage or of any guarantee pertaining thereto, in
                  any manner and to any extent that may be deemed advisable for
                  the protection of the Trust or the preservation of the value
                  of the investment, to waive any default whether in the
                  performance of any covenant or condition of any mortgage or
                  in the performance of any guarantee, or to enforce any such

                  under Section 401(a) and is exempt from tax under Section
                  501(a) of the Code, and which is maintained as a medium for
                  the collective investment of funds of pension, profit-sharing
                  or other employee benefit trusts, or to any other trustee of
                  such a trust, in which event such trust shall be deemed to be
                  a part of the Plan, and to withdraw any assets of the Trust
                  so transferred;

             (i)  when instructed or directed by the Administrator, to settle,

                  the Trustee shall have no obligation to take any legal action
                  for the benefit of the Trust unless it shall have been first
                  indemnified for all expenses in connection therewith,
                  including counsel fees;



                                      - 10 -
             (j)  to lend to Plan members such amount or amounts, and upon such
                  terms and conditions, as the Administrator may direct in
                  accordance with the provisions of the Plan, if applicable;

             (k)  to employ such agents, consultants, custodians, depositories,
                  advisors, and legal counsel as may be reasonably necessary or
                  desirable in the Trustee's judgment in managing and
                  protecting the Trust and, subject to the provisions of
                  Section 14, to pay them reasonable compensation out of the

             (l)  to cause any securities or other property which may at any

                  Trustee, any nominee of such a custodian, and any depository,
                  clearing corporation or other similar system), or in such
                  form that title will pass by delivery;

             (m)  to enter into stand-by agreements for future investment
                  either with or without a stand-by fee;

             (n)  to transfer any assets of the Trust to a custodian or sub-
                  custodian employed by the Trustee;

             (o)  when directed by the Administrator, to participate in a
                  securities lending program sponsored and administered by the
                  Trustee and, in connection therewith, the Trustee is
                  authorized to release and deliver securities and return
                  collateral received for loaned securities in accordance with
                  the provisions of such program;

             (p)  to write options on securities held or to otherwise
                  participate in so-called covered option writing; and

             (q)  to do all other acts in its judgment necessary or desirable
                  for the proper administration of the Trust, in accordance
                  with the provisions of the Plan and this Agreement, although
                  the power to do such acts is not specifically set forth
                  herein.

             No person dealing with the Trustee shall be required to take any
             notice of this Agreement, but all persons so dealing shall be
             protected in treating the Trustee as the absolute owner with full
             power of disposition of all the monies, securities and other
             property of the Trust, and all persons dealing with the Trustee
             are released from inquiry into the decision or authority of the
             Trustee and from seeing to the application of monies, securities
             or other property paid or delivered to the Trustee.

          11.     LIQUIDATION OF ASSETS.  Upon termination of the Trust as
                  provided herein, the Trustee shall not be required to make
                  any payments hereunder until it has received such
                  documentation as it shall consider necessary to establish
                  that the termination complies with applicable law, or to make
                  any payments in excess of the net realizable value of the
                  assets of the Trust at the time of such payment.  The Trustee
                  shall not be required to make any payments in cash unless
                  there shall be in the Trust at the time an amount of cash
                  sufficient for the purpose.  In case of a deficiency in cash,
                  the Trustee shall take such action as to the disposition of

                                      - 11 -
                  securities or other property forming a part of the Trust as
                  will provide the amount of cash for such payments.  The
                  Trustee shall not be required to make any payment in cash
                  until the Administrator has provided direction as to the
                  assets to be converted to cash for the purpose of making such
                  payment.

          12.     DIRECTION BY COMPANY OR ADMINISTRATOR.  The Company shall
                  certify to the Trustee the names and specimen signatures of
                  the Administrative Committee.  The Company shall give prompt
                  notice to the Trustee of changes in the Administrative
                  Committee, and until such notice is received by the Trustee,
                  the Trustee shall be fully protected in assuming that the
                  Administrative Committee is unchanged and in acting
                  accordingly.  The Administrative Committee may certify to the
                  Trustee the names of persons authorized to act for it in
                  relation to the Trustee and may designate a person,
                  corporation or other entity, whether or not affiliated with
                  the Company, to so act.   Whenever the Trustee is required or
                  authorized to take any action hereunder pursuant to any
                  written direction or determination of the Company or the
                  Administrator, such direction or determination shall be
                  sufficient protection to the Trustee if contained in a
                  writing signed by any one or more of the persons authorized
                  to execute documents on behalf of the Company or the
                  Administrator, as the case may be, pursuant to the Plan.  The
                  Trustee shall act, and shall be fully protected in acting, in
                  accordance with such orders, requests and instructions of the
                  Company or the Administrator.  By such a writing the Company
                  or the Administrator, as the case may be, may ratify, approve
                  or confirm any action taken by the Trustee, and upon such
                  ratification, approval or confirmation the Trustee shall be
                  protected as though authorization or determination by the
                  Company or the Administrator had preceded such action.  In
                  the absence of direction by the Company or the Administrator
                  as to any matter provided in this Agreement or the Plan, the
                  Trustee may in its discretion take such action as it deems
                  fit and proper with respect thereto after reasonable attempts
                  to secure Company or Administrator direction, provided,
                  however, that the Trustee shall not be obligated to take any
                  such action.  The Trustee may deliver documents to the
                  Company or the Administrator by delivering the same, or by
                  mailing the same, postage prepaid, addressed to the Company
                  or the Administrative Committee, as the case may be, at its
                  principal place of business.

          13.     RECORDS AND ACCOUNTING.  The Trustee shall keep adequate and
                  accurate accounts of investments, receipts, disbursements and
                  other transactions hereunder, and all accounts, books and
                  records relating thereto shall be open at all reasonable
                  times to inspection and audit by the Administrator and its
                  authorized representatives.  The Trustee shall render to the
                  Company and the Administrator in writing, at least once each
                  twelve (12) months and at such times as required by the Plan
                  and, in any event, within ninety (90) days after its removal
                  or resignation as provided in Section 15 hereof, accounts of
                  its transactions under this Agreement, and the Administrator
                  may approve such accounts of the Trustee by an instrument in
                  writing delivered to the Trustee.  In the absence of the
                  filing in writing with the Trustee by the Administrator of
                  exceptions or objections to any such account within one year

                                      - 12 -
                  after the receipt thereof, the Administrator shall be deemed
                  to have approved such account; and in such case, or upon the
                  written approval of the Administrator of any such account,
                  the Trustee, to the extent permitted by applicable law, shall
                  be released, relieved and discharged with respect to all
                  matters and things set forth in such account.  The Trustee
                  shall from time to time make such other reports and furnish
                  such other information concerning the Trust (including
                  valuations of each Investment Fund established pursuant to
                  Section 6) to the Administrator as the Administrator may
                  reasonably request or as may be required by the Plan.  The
                  Administrator shall arrange for each Investment Manager
                  appointed pursuant to Section 8, and each insurance company
                  issuing contracts held by the Trustee pursuant to Section 9,
                  to furnish the Trustee with such valuations and reports as
                  are necessary to enable the Trustee to fulfill its
                  obligations under this Section 13, and the Trustee shall be
                  fully protected in relying upon such valuations and reports. 
                  In any proceeding instituted by the Trustee, the Company or
                  the Administrator or all of them with respect to any account
                  of the Trustee, only the Company, the Administrator and the
                  Trustee shall be necessary parties.

          14.     TRUSTEE'S COMPENSATION AND EXPENSES.  The Trustee shall be
                  paid such reasonable compensation as provided in the service
                  agreement between the Company and the Trustee or its
                  affiliate.  The compensation of the Trustee and any
                  reasonable expenses, including reasonable attorneys' fees and
                  the cost of any bond, surety or other security which may be
                  required of the Trustee by ERISA, incurred by the Trustee in
                  the performance of its duties, and all other proper charges
                  and disbursements of the Trustee may be paid by the Company
                  within thirty (30) days after so billed, and will
                  automatically be deducted from the Trust if, upon the
                  expiration of thirty (30) days, such fees are not separately
                  paid by the Company.  All expenses (including taxes pursuant
                  to Section 21) of the Trust, other than those expenses which
                  are paid by the Company, which are allocable to an Investment
                  Fund established pursuant to Section 6 shall be charged to
                  such Investment Fund.  All such expenses which are not so
                  allocable shall be charged against each of the Investment
                  Funds in the same proportion as the value of the assets held
                  in such Investment Fund bears to the value of the total
                  assets held in all of the Investment Funds.  Any account
                  maintenance or administration fees applicable to any Plan
                  member's account which are not paid hereunder by the Company
                  shall be charged against the interest of the Plan member and,
                  in the case of a loan of a Plan member, if applicable, all
                  expenses (including taxes pursuant to Section 21) of the
                  Trust, other than those expenses which are paid by the
                  Company, which are allocable to such loan, shall be charged
                  against the interest of such Plan member under the Plan.

          15.     RESIGNATION OR REMOVAL OF TRUSTEE.  The Trustee may resign at
                  any time upon sixty (60) days' written notice to the Company,
                  and the Company may remove the Trustee at any time upon sixty
                  (60) days' written notice to the Trustee; provided, however,
                  that the parties may by written instrument waive such notice. 
                  The Trustee reserves the right at any time to resign
                  immediately if the Company transfers the Plan's
                  administration to a recordkeeper other than the recordkeeper

                                      - 13 -
                  designated in the service agreement between the Company and
                  the Trustee or its affiliate, a copy of which is attached
                  hereto, without the Trustee's prior written consent, by
                  delivering to the Company a notice of resignation certified
                  by the Trustee.  The Trustee further reserves the right at
                  any time to resign immediately by delivering to the Company a
                  notice of resignation certified by the Trustee if the assets
                  of the Trust are not invested in investment products which
                  are sponsored, underwritten or managed by affiliates of the
                  Trustee, unless the service agreement between the Company and
                  the Trustee or its affiliates otherwise specifically
                  provides.  If the Trustee shall resign, be removed or for any
                  other reason cease to be Trustee, the Company shall appoint a
                  successor Trustee or Trustees to whom the Trustee, upon
                  receipt of acceptance by such successor, shall promptly
                  deliver all of the assets of the Trust less any unpaid fees
                  or expenses.  Subject to the foregoing provisions, any
                  resignation or removal of the Trustee or appointment of a new
                  Trustee shall be by instrument in writing and shall become
                  effective on the date therein specified.  Any successor
                  Trustee shall have the same powers and duties as the
                  succeeded Trustee, subject to such changes as the Company may
                  then determine.  Upon request of such successor Trustee or
                  Trustees, the Company and the Trustee ceasing to act shall
                  execute and deliver such instruments of conveyance and
                  further assurance and do such things as may reasonably be
                  required for more fully and certainly vesting and confirming
                  in such successor Trustee or Trustees all the right, title
                  and interest of the retiring Trustee in and to the assets of
                  the Trust.  The Trustee is authorized, however, to reserve
                  such sums of money as may be reasonable for payment of its
                  compensation and expenses (including legal fees) in
                  connection with the settlement of its account or otherwise,
                  and any balance of such reserve remaining after payment of
                  such compensation and expenses shall be promptly paid over to
                  the successor Trustee or Trustees.

          16.     DUTIES OF TRUSTEE.  The Trustee shall discharge its duties
                  with respect to the Trust solely in the interests of the Plan
                  members and their beneficiaries and with the care, skill,
                  prudence and diligence under the circumstances then
                  prevailing that a prudent man acting in a like capacity and
                  familiar with such matters would use in the conduct of an
                  enterprise of like character and with like aims.  The duties
                  of the Trustee shall be only those specifically undertaken by
                  the Trustee pursuant to this Trust Agreement.  The Trustee
                  shall have no responsibility for the administration of the
                  Plan (including, but not limited to, the determination of
                  Plan participation rights of employees of the Company, the
                  determination of benefits of members of the Plan and the
                  maintenance of individual accounts of members of the Plan). 
                  Except as otherwise provided by ERISA, in no event shall the
                  Trustee be responsible for any act or omission of any other
                  fiduciary of the Plan.  The Trustee shall have no liability
                  for the acts or omissions of any predecessors and successors
                  in office.

          17.     INDEMNIFICATION.  The Company hereby agrees to indemnify and
                  hold harmless the Trustee from and against any losses,
                  damages, liabilities, claims, costs or expenses (including
                  reasonable attorneys' fees) which the Trustee may incur by

                                      - 14 -
                  reason of this Trust Agreement, (including, without
                  limitation, by reason of the Trustee's making benefit
                  payments pursuant to fraudulent or unauthorized instructions)
                  excepting only losses, damages, liabilities, claims, costs or
                  expenses arising from the Trustee's negligence or willful
                  misconduct.  A waiver by the Trustee of any signature
                  guarantee requirement relating to the investments held
                  hereunder shall not be construed as negligence or willful
                  misconduct on the part of the Trustee.

          18.     AMENDMENT OR TERMINATION.  The Company reserves the right at
                  any time and from time to time to amend, in whole or in part,
                  any or all of the provisions of, or to terminate, this
                  Agreement by delivering to the Trustee a copy of an amendment
                  or a notice of termination certified by an officer of the
                  Company; provided, that no such amendment which affects the
                  rights, duties or responsibilities of the Trustee may be made
                  without its consent, and provided further that no such
                  amendment shall authorize or permit any part of the corpus or
                  income of the Trust to be used for or diverted to purposes
                  other than those set forth in Section 3. Any such amendment
                  shall be effective upon delivery to the Trustee unless a
                  different effective date is specifically stated and any such
                  amendment may be made retroactively as shall be permitted
                  under applicable law. Upon termination of this Agreement, the
                  Trustee, upon direction of the Administrator shall liquidate
                  the Trust to the extent required for distribution and, after
                  the final account of the Trustee has been approved and
                  settled, shall distribute the balance of the Trust remaining
                  in its hands as directed by the Administrator or in the
                  absence of such direction, as may be directed by a judgment
                  or decree of a court of competent jurisdiction.  Following
                  any such termination the powers of the Trustee hereunder
                  shall continue as long as any of the assets of the Trust
                  remain in its hands, but only as to those assets which during
                  such time remain in the Trust.

          19.     ADDITIONAL PARTICIPATING COMPANIES.  Any affiliate or
                  subsidiary of the Company may, with the consent of the
                  Company, become a participating employer by action of the
                  board of directors of such affiliate or subsidiary to adopt
                  the Trust as a trust for the benefit of its employees.  Each
                  such additional participating employer shall be deemed the
                  "Company" hereunder and shall have and exercise all the
                  rights, powers, and duties thereof with respect to the Trust
                  as applied to itself and its employees and that part of the
                  Trust which represents the interest of members employed by
                  it; provided, however, that each such additional
                  participating employer hereby delegates all such rights,
                  powers, and duties, including amendment or termination of the
                  Trust, to Connecticut Natural Gas Corporation acting alone,
                  except as such additional participating employer may exercise
                  the same for itself with the approval of Connecticut Natural
                  Gas Corporation.

          20.     SPENDTHRIFT PROVISION.  Except as otherwise provided in the
                  Plan, to the maximum extent permitted by law, beneficial
                  interests in the Trust of members or former members under the
                  Plan or their beneficiaries shall not be assignable nor
                  subject to alienation, sale, transfer, pledge, encumbrance,
                  mortgage, attachment, execution, levy or receivership, nor

                                      - 15 -
                  shall they pass to any trustee in bankruptcy or be reached or
                  applied by any legal process for the payment of any
                  obligations of any such person; provided, however, that
                  nothing herein shall prevent a member from assigning his
                  interest in the Trust as security for the repayment of any
                  loan made to him from the Trust pursuant to the Plan, and
                  further provided that nothing herein shall prevent the
                  Trustee from making payments in accordance with a Qualified
                  Domestic Relations Order, as that term is defined in Code
                  Section 414(p).  Any attempt at any other assignment,
                  alienation, sale, transfer, pledge, encumbrance, mortgage,
                  attachment, execution or levy shall be void and
                  unenforceable.

          21.     PAYMENT OF TAXES.  The Trustee may pay out of the Trust (or
                  the appropriate Investment Fund or Funds) any and all taxes
                  of any and all kinds, including without limitation property
                  taxes and income taxes levied or assessed under existing or
                  future laws upon or in respect of the Trust or any monies,
                  securities or other property forming a part thereof or the
                  income therefrom subject to the terms of any agreements or
                  contracts made with respect to trust investments which make
                  other provision for such tax payments.  The Trustee may
                  assume that any taxes assessed on or in respect of the Trust
                  or its income are lawfully assessed unless the Administrator
                  shall in writing advise the Trustee that in the opinion of
                  counsel for the Company such taxes are or may be unlawfully
                  assessed.  In the event that the Administrator shall so
                  advise the Trustee, the Trustee will, if so requested in
                  writing by the Administrator contest the validity of such
                  taxes in any manner deemed appropriate by the Company or its
                  counsel but at the expense of the Trust; or the Company may
                  contest the validity of any such taxes at the expense of the
                  Trust and in the name of the Trustee; and the Trustee agrees
                  to execute all documents, instruments, claims, and petitions
                  necessary or advisable in the opinion of the Company or its
                  counsel for the refund, abatement, reduction or elimination
                  of any such taxes.  At the direction of the Administrator the
                  Trustee shall collect all income tax to be withheld from any
                  benefit payments from the Trust and shall report and pay over
                  such taxes to the Internal Revenue Service, except for
                  payments made directly by an insurer to a Plan member or
                  beneficiary under an annuity or insurance contract, if
                  applicable.

          22.     SUCCESSOR TO COMPANY OR TRUSTEE.  Any successor to all or a
                  major part of the business of the Trustee, by whatever form
                  or manner resulting, shall ipso facto succeed to all the
                  rights, powers and duties hereunder of the Trustee.  Any
                  successor to all or a major part of the business of the
                  Company, by whatever form or manner resulting, may continue
                  the Plan and Trust by executing appropriate amendments
                  thereto, and thereupon such successor shall ipso facto
                  succeed to all the rights, powers and duties hereunder of the
                  Company.

          23.     CONSTRUCTION.  In any question of interpretation or other
                  matter of doubt, the Trustee, the Administrator and the
                  Company may rely upon the opinion of counsel for the Company
                  or any other attorney at law designated by the Company with
                  the approval of the Trustee.  The provisions of this

                                      - 16 -
                  Agreement shall be construed, administered and enforced
                  according to the laws of the United States and, to the extent
                  permitted by such laws, by the laws of the Commonwealth of
                  Massachusetts.  All contributions to the Trust shall be
                  deemed to be made in the Commonwealth of Massachusetts.

          24.     IMPOSSIBILITY OF PERFORMANCE.  In case it becomes impossible
                  for the Company, the Administrator or the Trustee to perform
                  any act under this Trust Agreement, that act shall be
                  performed which in the judgment of the Administrator will
                  most nearly carry out the intent and purpose of the Plan and
                  Trust. All parties to this Agreement or in any way interested
                  in the Trust shall be bound by any acts performed under such
                  condition.

          25.     DEFINITION OF WORDS.  Feminine or neuter pronouns shall be
                  substituted for those of the masculine form, and the plural
                  shall be substituted for the singular, in any place or places
                  herein where the context may require such substitution or
                  substitutions.

          26.     TITLES.  The titles of sections are included only for
                  convenience and shall not be construed as part of this
                  Agreement or in any respect affecting or modifying its
                  provisions.
