under and secured by a certain Second Amended and Restated First
Mortgage Indenture dated as of June 15, 1992, as supplemented by
the First and Second Supplemental Indentures, inclusive, executed
counterparts of which are on file with the Trustee and may be
examined at its principal corporate trust office in Canton,
Massachusetts.  Said Second Amended and Restated First Mortgage
Indenture, as amended and so supplemented, is herein generally
called the Indenture.  Reference is made to the Indenture for a
description of Bonds outstanding under the Indenture as of
particular dates, including Prior Series Bonds as defined in the
Indenture, for a description of the property mortgaged and
pledged to the Trustee as security for Bonds, for a statement of
the nature and extent of the security, the terms and conditions
upon which Bonds have been, are or are to be issued and secured,
the rights and remedies under the Indenture of the holders of all
of said Bonds, and the rights and obligations under the Indenture
of the Company and of the Trustee, and for the definitions of
certain terms used but not defined in this Note; but neither the
foregoing reference to the Indenture, nor any provision of this
Note or of the Indenture, shall affect or impair the obligation
of the Company, which is absolute, unconditional and unalterable,
to pay, at the stated or accelerated maturities herein provided,
the principal of and premium, if any, and interest on this Note
as herein provided.  By the terms of the Indenture, the Bonds to
be secured thereby are issuable to an unlimited (except as

which may vary as to date, amount, date of maturity, rate of
interest and in other respects as in the Indenture provided.

     In certain events, on the conditions, in the manner, to the
extent and with the effect set forth in the Indenture,

          (1)  the principal of this Note may be declared and/or
     may become due and payable before the stated maturity
     hereof, together with the interest accrued hereon;

          (2)  the Company and the Trustee may make modifications
     or alterations of the provisions of the Indenture and of
     this Note with the consent of the holders of not less than
     66 2/3% in principal amount of the Bonds outstanding under the
     Indenture, including not less than 66 2/3% in principal amount
     of the Bonds of any series or sub-series affected in any
     manner or to any extent differing from that in or to which
     the Bonds of any other series or sub-series are affected;
     provided, however, that no such alteration or modification
     shall, without the consent of the registered owner of this
     Note, (a) impair the obligation of the Company in respect of
     the principal of or premium, if any, or interest on this
     Note, or extend the maturity hereof or change the rate or
     extend the time of payment of interest hereon or modify the
     terms of payment of such principal, premium, if any, or
     interest, or (b) permit the creation of any lien prior to or
     on a parity with the lien of the Indenture, except as
     expressly authorized by the Indenture, or (c) alter the
     percentages of the principal amount of Bonds required to
     declare the principal of and interest accrued on all Bonds
     outstanding immediately due and payable as a result of a
     default under the Indenture or to annul such declaration, or
     (d) reduce the percentage of the principal amount of Bonds
     with the consent of the holders of which modifications or
     alterations may be made as aforesaid;

          (3)  the holders of not less than 66 2/3% in principal
     amount of the Bonds at the time outstanding under the
     Indenture, including not less than 66 2/3% in principal amount
     of the Bonds of any series or sub-series affected by the
     waiver in a manner different from that of any other series
     or sub-series, may waive any existing default under the
     Indenture and the consequences of any such default, except a
     default in the payment of the principal of, premium, if any,
     or interest on any of the Bonds, and except a default
     arising from the creation of any lien prior to or on a
     parity with the lien of the Indenture;

          (4)  upon payment of charges and compliance with other
     conditions as provided in the Indenture, the Series A Notes
     are exchangeable, at the principal corporate trust office of
     the Trustee and at such other offices or agencies of the
     Trustee or of the Company as may be designated for the
     purpose, for like aggregate principal amounts of Series A
     Notes in authorized denominations; and this Note is
     transferable on books kept by the Company at said office of
     the Trustee and at such other offices or agencies, upon
     surrender and cancellation hereof at any such office or
     agency, duly endorsed or accompanied by a duly executed
     instrument of transfer, and thereupon a new fully registered
     Series A Note or Notes for a like aggregate principal amount
     will be issued to the transferee or transferees in exchange
     for this Note; and

          (5)  the Series A Notes (i) are subject to redemption
     in whole or in part at any time prior to maturity if through
     the application of eminent domain moneys or the proceeds of
     insurance arising from loss or casualty, as specified in the
     Indenture, at the principal amount thereof, and (ii) to the
     extent specified in the attached table, if any, are subject
     to redemption, in whole or in part, at any time prior to
     maturity, at the option of the Company, on and after the
     initial redemption date specified in the attached table, at
     the applicable redemption prices (expressed as a percentage
     of the principal amount) set forth in the attached table,
     together in each case with accrued interest to the date
     fixed for redemption.  Any redemptions permitted or required
     under the Indenture, other than those described in (i), will
     be deemed optional redemptions.

     At least thirty (30) but not more than sixty (60) days prior
to the date on which any Series A Note is to be redeemed as
aforesaid, written notice of such redemption shall be given by
registered mail to the registered owners of the Series A Notes
all or any portions of which are to be redeemed.  If this Note is
called in whole or in part, after provision has been duly made
for notice of such call and after deposit shall have been made of
the principal, premium, if any, and interest to the date fixed
for redemption and such amounts are immediately available on the
date fixed for redemption to the holders of the Series A Notes to
be redeemed on surrender thereof, this Note, or such called part
of the principal amount hereof, shall cease to be secured by the
lien of the Indenture, no interest shall accrue on this Note or
such called part hereof on and after the date fixed for
redemption, and the Company after said date fixed for redemption
shall be under no further liability in respect of the principal
of or premium, if any, or interest on this Note or such called
part hereof (except as expressly provided in the Indenture); and
if less than the whole principal amount hereof shall be so
called, the registered owner hereof shall be entitled, in
addition to the sums payable on account of the part called, to
receive, without expense to such owner, on surrender of this Note
duly endorsed or accompanied by a duly executed instrument of
transfer, one or more Series A Notes for an aggregate principal
amount equal to that part of the principal amount hereof not then
called and paid, or to present this Note for the notation hereon
of the payment of the part of the principal amount then called
and paid.

     This Note is not subject to redemption under any provision
of the Indenture, or otherwise, except as expressly referenced
above.

     The Company, the Trustee, any paying agent, any bond
registrar and any other person may treat the registered owner
hereof as the absolute owner hereof for the purpose of receiving
payment of the principal of and premium, if any, and interest on
this Note and for all other purposes, and neither the Company nor
the Trustee, nor any paying agent or bond registrar, shall be
affected by any notice or knowledge to the contrary, whether
payments on this Note shall be overdue or not.  The Company, and
every successive owner and assignee of this Note, by accepting
and holding the same, consents and agrees to the foregoing
provisions, and each invites the others and all persons to rely
thereon.

     No recourse shall be had for the payment of the principal of
or premium, if any, or interest on this Note against any
incorporator, stockholder, director, officer or agent, past,
present or future, as such, of the Company or of any predecessor
or successor corporation, either directly or through the Company
or any such predecessor or successor corporation, under any rule
of law, statute or constitution or by the enforcement of any
assessment or otherwise, all such liability of incorporators,
stockholders, directors, officers and agents being released by
the holder hereof by the acceptance of this Note and being
likewise waived and released as provided in the Indenture,
provided that nothing herein or in the Indenture shall prevent
enforcement of obligations on stock not fully paid up.

     This Note shall take effect as a sealed instrument.

     This Note shall not be valid or become obligatory for any
purpose or be entitled to any security or benefit under the
Indenture until the certificate hereon shall have been signed by
the Trustee.

     IN WITNESS WHEREOF, Colonial Gas Company has caused this
Note to be executed under its corporate seal and issued by its
duly authorized officers, all as of _________________ __, 19__.

aggregate principal amount of Series A Notes for the issue of
which provision is made herein, and of the holders of all the
Bonds from time to time certified, issued and outstanding under

reserved and excepted, upon the trusts of the Indenture set forth

mortgaged, transferred and assigned to and vested in the Trustee
by the Indenture.

                           ARTICLE I

                         Series A Notes

     Section 1.01. General Terms of Series A Notes.  The second
series of Bonds to be issued under the Indenture shall be known
as "Secured Medium Term Notes, Series A."  Such Series A Notes
shall be limited in aggregate principal amount to $75,000,000.
The Series A Notes shall be issued from time to time as fully
registered Bonds, without coupons, and no coupon bonds shall be
issued, whether upon original issue or upon transfers or
exchanges.  The Series A Notes shall be substantially in the form
hereinbefore recited and, in each case, shall recite the
principal amount, interest rate, maturity, redemption or call
provisions and other provisions thereof, which may vary as among
the Series A Notes.  The Series A Notes may be issued in the
denomination of one thousand dollars ($1,000) each or any
multiple thereof and, without regard to the denomination thereof,
shall be numbered consecutively.  Each Series A Note shall be
dated as of the day of certification, except that Series A Notes
issued upon transfers and exchanges of Series A Notes and upon
exchanges of temporary Bonds for such Series A Notes shall be
dated so that no gain or loss of interest shall result from such
transfer or exchange.  The Series A Notes shall be due and
payable on such dates, and shall bear interest at such rates (in
each case computed on the basis of a 360-day year of twelve
30-day months from the date thereof) as may be specified therein
from the date of issuance.  Interest thereon shall be payable
semi-annually, on February 15 and August 15 in each year, and at
maturity, until the principal thereof shall become due and
payable.  The Company also agrees to pay on demand interest on
any overdue principal (including any overdue prepayment of
principal) and premium, if any, at a rate equal to the interest
rate of the relevant Series A Note, plus one percent (1.00%) per
annum and, to the extent permitted by law, interest on any
overdue installment of interest at the rate at which such overdue
installment of interest was calculated according to the terms of
the Series A Notes.  The Series A Notes shall be payable as to
principal, premium, if any, and interest at, unless the holder of
any such Bond and the Company shall have otherwise agreed in
writing, the principal corporate trust office of the Trustee in
Canton, Massachusetts, or at the principal office of its
successor in trust created by the Indenture or, at the option of
the registered owner thereof, at such other office or agency of
the Trustee or of the Company maintained by it for the purpose 
in the Burough of Manhattan, The City of New York, New York, or
such other place as may be designated for the
purpose pursuant to the provisions hereof, in lawful money of 
the United States of America.

     The Series A Notes shall be exchangeable by the holders, and
may be transferred, in each case as provided in section 2.06 of
the Indenture, all upon payment of charges and otherwise as
provided in the Indenture.

     The Series A Notes are not subject to redemption, at the
option of the Company or otherwise, by operation of the
provisions of the Indenture, whether under sections 7.02 and 7.03
of the Indenture, or otherwise, except as specifically set forth
in the form of such Notes.

     Series A Notes at any time outstanding may be called for
redemption in the manner provided in Article 5 of the Indenture
and section 1.03 hereof (i) in whole or in part, at any time
prior to maturity, at the option of the Company, to the extent,
under the provisions of and at the redemption prices specified in
the resolution of the Company providing for the issue of such
Series A Notes (the "Resolution") and set forth in the related
Series A Notes or (ii) in whole or in part at
any time prior to maturity through the application of eminent
domain moneys (as hereinafter defined) or the proceeds of
insurance arising from loss or casualty under the provisions of
the Indenture at the principal amount thereof; together in each
case with unpaid interest accrued to the date fixed for
redemption.  Any redemptions permitted or required under the
Indenture, other than those described in (ii) above, shall be
deemed optional redemptions.  The term "eminent domain moneys"
shall mean the net proceeds of the taking of property included in
the trust estate by exercise of the power of eminent domain, or
by similar right or power, or the purchase or designation of the
purchaser of, or ordering of the sale of, all or any part of such
property by the exercise of any right of any governmental
authority, or the sale or conveyance in lieu and in reasonable
anticipation of any such event (provided that, in case of a sale
or conveyance in anticipation of any such event, "eminent domain
moneys" shall include, in addition to said net proceeds, the
excess of the fair value over the net proceeds, if the fair
value, as evidenced by an engineer's certificate, of the property
sold or conveyed, is greater than such net proceeds), together
with all net sums payable for any damage to any fixed assets
embraced in the trust estate by or in connection with any such
taking, sale or conveyance.

     Section 1.02. Payment of Interest.  Whenever Series A Notes
are called for redemption, the Company shall, in each case, prior
to the date fixed for redemption thereof, pay to the Trustee in
cash all unpaid interest accrued on such Series A Notes to said
date fixed for redemption.

     Section 1.03. Procedure for Redemption.  Except as otherwise
provided in this section 1.03 or the Resolution, the procedure
for redemption of Series A Notes shall be that specified in
sections 5.02, 5.03 and 5.04 of the Indenture.

     Notice of redemption of any Series A Notes shall be given by
the Company as provided in sections 5.02 and 5.03 of the
Indenture, except that, unless otherwise provided in the
Resolution, notice need be given only by mail and not by
publication.  Any such notice of redemption shall be mailed not
less than thirty (30) nor more than sixty (60) days prior to the
date on which the proposed redemption is to take place.  The
mailing of such notice shall be a condition precedent to
redemption, provided that any notice which is so mailed shall be
conclusively presumed to have been duly given, whether or not the
holders receive such notice, and failure to give such notice by
mail, or any defect in such notice, to the holder of any such
Series A Note designated for redemption, in whole or in part,
shall not affect the validity of the redemption of any other such
Series A Note.

     Section 1.04. Global Notes.  Notwithstanding any other
provisions of this Supplemental Indenture, the Series A Notes
issued by the Company and authenticated and delivered by the
Trustee under this Supplemental Indenture shall be issued as
definitive, fully-registered global notes in the name of Cede 
& Co., as nominee of The Depository Trust Company ("DTC"), in 
the aggregate principal amount of all Series A Notes issued
hereunder.

     The Company and the Trustee may treat DTC as, and shall deem
DTC to be, the absolute owner of the Series A Notes evidenced by
the global notes for the purpose of payment of principal of,
premium, if any, and interest on such Series A Notes, for the
purpose of all other matters with respect to such Series A Notes,
for the purpose of registering transfers with respect to Series A
Notes, and for all other purposes whatsoever.  Neither the
Company nor the Trustee shall have any responsibility or
obligation to any of DTC's direct or indirect participants.
Without limiting the immediately preceding sentence, neither the
Company nor the Trustee shall have any responsibility or
obligation with respect to (i) the accuracy of the records of DTC
or its nominee or any of its direct or indirect participants with
respect to any ownership interest in the global notes, (ii) the
delivery to any of DTC's direct or indirect participants or any
other person, other than DTC, of any notice with respect to the
Series A Notes evidenced by the global notes, (iii) the payment
to any of DTC's direct or indirect participants or any other
person, other than DTC, of any amount with respect to the
principal  of, premium, if any, or interest on the Series A Notes
evidenced by the global notes, and (iv) the failure of DTC to
provide any information or notification on behalf of any of DTC's
direct or indirect participants.  The Trustee shall pay all
principal of and premium, if any, and interest on the Series A Notes
only to or upon the order of DTC, and all such payments shall be
valid and effective to fully satisfy the Company's obligations
with respect to the principal of and premium, if any, and
interest on such Series A Notes to the extent so paid.
Notwithstanding the provisions of the Indenture to the contrary
(including, without limitation, place of payment, surrender of
the Series A Notes, registration and transfer thereof and
authorized denominations), as long as any of the Series A Notes
are in the form of a global note, full effect shall be given to
the procedures and practices of DTC with respect thereto, and the
Trustee shall comply therewith.

     In the event that (i) DTC (or any successor securities
depositary) is at any time unwilling or unable to continue as
depositary and a successor depositary is not appointed by the
Company within 90 days, (ii) the Company determines that the
continuation of the system of book-entry only transfers through
DTC (or a successor securities depositary) is not in the best
interests of the beneficial owners of the Series A Notes or is
burdensome to the Company, or (iii) a default under the Indenture
has occurred and is continuing, the Company will notify DTC and the
Trustee, whereupon DTC or the Trustee will notify DTC
participants of the availability through DTC of certificates for
the Series A Notes.  In such event, the Company and the Trustee
shall execute and deliver a supplemental indenture to add such
provisions and to make such modifications, including in the
form of Series A Note, as may be necessary or appropriate to provide
for the issuance of the Series A Notes in certificated form and
the Company shall issue and the Trustee shall transfer and 
exchange certificates for the Series A Notes as requested by DTC 
in denominations as prescribed by Section 1.01 hereof, to the
identifiable beneficial owners in replacement of such beneficial 
owners' respective beneficial interests in the Series A Notes.


                           ARTICLE II

                         Miscellaneous

     Section 2.01.  Certain Covenants.  For purposes of Sections
3.01(h) and 4.22 of the Indenture, and not for any other purpose,
the Series A Notes are hereby designated as Prior Series Bonds.

     Section 2.02.  Miscellaneous Provisions.  The Trustee shall
be entitled to, may exercise and shall be protected by, where and
to the full extent that the same are applicable, all the rights,
powers, privileges, immunities and exemptions provided in the
Indenture, as if the provisions concerning the same were
incorporated herein at length.  The Trustee under the Indenture
shall ex officio be Trustee hereunder.  The remedies and
provisions of the Indenture, applicable in case of any default by
the Company thereunder, are hereby adopted and made applicable in
case of any default with respect to the properties included
herein and, without limitation of the generality of the
foregoing, there are hereby conferred upon the Trustee the same
powers of sale and other powers over the properties described
herein as are expressed to be conferred by the Indenture.

     If, pursuant to Article I of this Supplemental Indenture or
any similar provision of any other supplemental indenture, the
Trustee makes payment of the redemption price of all or a portion
of any registered Series A Note directly to the registered owner
thereof without presentation or surrender thereof, the Trustee
shall have no responsibility to ascertain whether such registered
owner carries out its agreement not to dispose of such Note
without prior presentation or surrender thereof to the Trustee as
provided in said Article I or similar provision, and the Trustee
shall not be liable for any claim if arising out of or because of
the failure of such registered owner to carry out its said
agreement.

     The recitals in this Supplemental Indenture shall be taken
as recitals by the Company alone, and shall not be considered as
made by or as imposing any obligation or liability upon the
Trustee, nor shall the Trustee be held responsible for the
legality or validity of this Supplemental Indenture, and the
Trustee makes no covenants or representations, and shall not be
responsible, as to or for the effect, authorization, execution,
delivery or recording of this Supplemental Indenture, except as
expressly set forth in the Indenture.  The Trustee shall not be
taken impliedly to waive by this Supplemental Indenture any right
it would otherwise have.  As provided in the Indenture, this
Supplemental Indenture shall hereafter form a part of the
Indenture.

     The date of this Supplemental Indenture is intended as and
for a date for reference and for identification, the actual time
of the execution hereof being the date set forth in the
testimonium clause hereof.

     This Supplemental Indenture shall become void when the
Indenture shall be void.

     If any provision of this Supplemental Indenture limits,
qualifies or conflicts with the duties imposed by operation of
Section 318(c) of the Trust Indenture Act of 1939, as amended,
such imposed duties shall control.

     This Supplemental Indenture may be simultaneously executed
in any number of counterparts, each of which shall be deemed an
original; and all said counterparts executed and delivered, each
as an original, shall constitute but one and the same instrument,
which shall for all purposes be sufficiently evidenced by any
such original counterpart.

     IN WITNESS WHEREOF, Colonial Gas Company has caused this
Supplemental Indenture to be executed, and its corporate seal to
be hereto affixed, by its officers thereunto duly authorized, and
The First National Bank of Boston has caused this Supplemental
Indenture to be executed, and its corporate seal to be hereto
