ARTICLE II



SERIES G BONDS





Section 2.01

Specific Title, Terms and Forms.  There is hereby created and shall be outstanding under and secured by the Indenture a series of Bonds entitled "First Mortgage Bonds, 4.80% Series G, Due 2014" (herein called the "Series G Bonds"), limited in aggregate principal amount at any one time outstanding to Seventy-Five Million Dollars ($75,000,000).  The form of the Series G Bonds shall be substantially as set forth in Exhibit A hereto with such insertions, omissions, substitutions and variations as may be determined by the officers executing the same as evidenced by their execution thereof.



The Series G Bonds shall be issued as fully registered Bonds in denominations of $1,000,000 or any amount in excess thereof which is an integral multiple of $250,000 (except as may be necessary to reflect any principal amount not evenly divisible by $250,000 remaining after any partial redemption), or in such other denominations as the Trustee may approve.  The Series G Bonds shall be numbered G-1 and consecutively upwards, or in any other manner deemed appropriate by the Trustee.  The Series G Bonds shall mature on January 1, 2014 and shall bear interest from the date of issuance thereof (or from the most recent Interest Payment Date to which interest has been paid or duly provided for) at the rate of four and eighty one-hundredths percent (4.80%) per annum (computed on the basis of a 360-day year of twelve 30-day months).  Interest Payment Dates for the Series G Bonds shall be (i) January 1 and July 1 of each year, commencing July 1, 2004, and (ii) at the Stated Maturity of the principal.



Notwithstanding the otherwise applicable provisions of the Indenture, the principal and the Redemption Price of, and interest on, the Series G Bonds shall be payable by Federal funds bank wire transfer of immediately available funds so long as required by Section 5.1 of the Bond Purchase Agreements, each dated January 30, 2004, between the Company and the initial purchasers of the Series G Bonds (the "Bond Purchase Agreements") or, in the event Section 5.1 shall no longer be applicable, at the office or agency of the Company in New York, New York, in such coin or currency of the United States of America as at the time of payment is legal tender for public or private debts.



The Regular Record Date referred to in Section 3.09 of the Original Indenture for the payment of the interest on the Series G Bonds payable, and punctually paid or duly provided for, on any Interest Payment Date shall be the 15th day (whether or not a business day) of the calendar month next preceding such Interest Payment Date.



Section 2.02

No Sinking Fund; No Mandatory Scheduled Redemptions Prior to Final Maturity.  The Series G Bonds shall not be subject to any sinking fund or mandatory scheduled redemption prior to final maturity.



Section 2.03

Optional Redemption.  The Series G Bonds shall be redeemable at the option of the Company in whole at any time or in part from time to time prior to their Stated Maturity, at a redemption price equal to the principal amount of the Series G Bonds being prepaid plus accrued interest thereon to the date of such redemption together with a premium equal to the then applicable Make-Whole Amount.



The Company will give notice of any optional redemption of the Series G Bonds pursuant to this Section 2.03 to each Holder thereof not less than 30 days nor more than 60 days before the date fixed for such optional redemption, specifying (a) such date, (b) the principal amount of the Holder's Bond to be redeemed on such date, (c) that a premium may be payable, (d) the estimated premium, calculated as of the day such notice is given, and (e) the accrued interest applicable to the redemption.  Such notice of redemption shall also certify all facts, if any, which are conditions precedent to any such redemption.  Notice of redemption having been so given, the aggregate principal amount of the Series G Bonds specified in such notice, together with accrued interest thereon, and the premium, if any, payable with respect thereto shall become due and payable on the redemption date specified in such notice.  Two business days prior to the redemption date specified in such notice of optional redemption, the Company shall provide the Trustee and each Holder of a Bond written notice of whether or not any premium is payable in connection with such redemption, the premium, if any, calculated as of the second business day prior to the redemption date, and a reasonably detailed computation of the Make-Whole Amount.  The Trustee shall be under no duty to inquire into, may conclusively presume the correctness of, and shall be fully protected in acting upon the Companys calculation of any Make-Whole Amount.



For purposes of this Section 2.03, the term "Make-Whole Amount" shall mean in connection with any optional redemption of the Series G Bonds the excess, if any, of (a) the aggregate present value as of the date of such redemption of each dollar of principal amount of Series G Bonds being redeemed and the amount of interest (exclusive of interest accrued to the date of redemption) that would have been payable in respect of such dollar if such redemption had not been made, determined by discounting such amounts at the Reinvestment Rate from the respective dates on which they would have been payable, over (b) 100% of the principal amount of the outstanding Series G Bonds being redeemed.



The "Reinvestment Rate" means (1) the sum of .50% plus the yield reported on page "USD" of the Bloomberg Treasury/Money Market Monitor Screen (or, if not available, any other nationally recognized trading screen reporting on-line intraday trading in United States government securities) at 12:00 noon (New York time) on such date for United States government securities having a maturity rounded to the nearest month corresponding to the remaining Weighted Average Life to Maturity of the principal being redeemed, prepaid or paid or (2) in the event that no such nationally recognized trading screen reporting on-line intraday trading in United States government Securities is available, Reinvestment Rate means .50 plus the arithmetic mean of the yields under the respective headings "This Week" and "Last Week" published in the Statistical Release under the caption "Treasury Constant Maturities" for the maturity (rounded to the nearest month) corresponding to the Weighted Average Life to Maturity of the principal being redeemed.  If no maturity exactly corresponds to such Weighted Average Life to Maturity, yields for the two published maturities most closely corresponding to such Weighted Average Life to Maturity shall be calculated pursuant to the immediately preceding sentence, and the Reinvestment Rate shall be interpolated or extrapolated from such yields on a straight-line basis, rounding in each of such relevant periods to the nearest month.  For purposes of calculating the Reinvestment Rate, the most recent Statistical Release published prior to the date of determination of the Make-Whole Amount shall be used.



For purposes of this Section 2.03, "Weighted Average Life to Maturity" of the principal amount of the Series G Bonds being redeemed shall mean, as of the time of any determination thereof, the number of years obtained by dividing the then Remaining Dollar-Years of such principal by the aggregate amount of such principal.  The term "Remaining Dollar-Years" of such principal shall mean the amount obtained by multiplying the amount of principal that would have become due at the Stated Maturity of the Series G Bonds if such redemption had not been made by the number of years (calculated to the nearest one-twelfth) which will elapse between the date of determination and the Stated Maturity of the Series G Bonds.



As used in this Section 2.03, "Statistical Release" shall mean the then most recently published statistical release designated "H.15(519)" or any successor publication which is published weekly by the Federal Reserve System and which establishes yields on actively traded United States government securities adjusted to constant maturities or, if such statistical release is not published at the time of any determination hereunder, then such other reasonably comparable index which shall be designated by the holders of 66-2/3% in aggregate principal amount of the outstanding Series G Bonds.



The principal amount, if any, of the Series G Bonds to be redeemed pursuant to this Section 2.03 shall be selected on a pro rata basis from all Series G Bonds Outstanding on the Redemption Date.



The Series G Bonds shall not be redeemable at the option of the Company prior to their Stated Maturity other than as provided in this Section 2.03.



Section 2.04.

Place of Payment.  The principal and the Redemption price of, and the premium, if any, and the interest on, the Series G Bonds shall be payable at the principal corporate trust office of The Bank of New York, in New York, New York.



Section 2.05.

Exchangeability.  Subject to Section 3.07 of the Original Indenture, all Series G Bonds shall be fully interchangeable, and, upon surrender at the office or agency of the Company in a Place of Payment therefor, shall be exchangeable for other Series G Bonds of a different authorized denomination or denominations, as requested by the Holder surrendering the same.  The Company will execute, and the Trustee shall authenticate and deliver, Series G Bonds whenever the same are required for any such exchange.



Section 2.06.

Bond Purchase Agreements.  Reference is made to Sections 5 and 7 of the Bond Purchase Agreements for certain provisions governing the rights and obligations of the Company, the Trustee and the Holders of the Series G Bonds.  Such provisions are deemed to be incorporated in this Article II by reference as if set forth herein at length.



Section 2.07.

Restrictions on Transfer.  All Series G Bonds originally issued hereunder shall bear the following legend:

Yankee Gas Services Company, a specially chartered Connecticut corporation (hereinafter called the "Company", which term includes any successor corporation under the Indenture hereinafter referred to), for value received, hereby promises to pay to [___________], or registered assigns, at the Stated Maturity set forth above, the Principal Amount set forth above (or so much thereof as shall not have been paid upon prior redemption) and to pay interest (computed on the basis of a 360-day year of twelve 30-day months) thereon from the date of issuance hereof or from the most recent Interest Payment Date to which interest has been paid or duly provided for, on each Interest Payment Date set forth above in each year at the Applicable Rate set forth above.  The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in said Indenture, be paid to the Person in whose name this Bond (or one or more Predecessor Bonds, as defined in said Indenture) is registered at the close of business on the Regular Record Date for such interest, which shall be the 15th day (whether or not a business day) of the calendar month next preceding such Interest Payment Date.  Any such interest not so punctually paid or duly provided for shall be paid to the Person in whose name this Bond is registered on the business day immediately preceding the date of such payment.  If all or any portion of the principal of, or the premium (if any) or interest on, this Bond shall not be paid when due, the amount not so paid shall bear interest at the lesser of (x) the highest rate allowed by applicable law or (y) the greater of (i) the Prime Rate (as defined in the Bond Purchase Agreements) or (ii) 5.80% (the Applicable Rate plus 1% per annum).



The principal and the Redemption Price of, and the interest on, this Bond shall be payable at the principal corporate trust office of The Bank of New York, in New York, New York.  All such payments shall be made in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.



This Bond is one of a duly authorized issue of Bonds of the Company designated as its "First Mortgage Bonds" (herein called the "Bonds"), issued and to be issued in one or more series under, and all equally and ratably secured by, an Indenture of Mortgage and Deed of Trust, dated as of July 1, 1989, (herein, together with any indenture or instruments supplemental thereto, including the First Supplemental Indenture dated as of April 1, 1992, the Second Supplemental Indenture dated as of December 1, 1992, the Third Supplemental Indenture dated as of June 1, 1995, the Fourth Supplemental Indenture dated as of April 1, 1997, the Fifth Supplemental Indenture dated as of January 1, 1999, and the Sixth Supplemental Indenture dated as of January 1, 2004, called the "Indenture"), between the Company and The Bank of New York, successor to Fleet National Bank (formerly known as The Connecticut National Bank), as Trustee (herein called the "Trustee," which term includes any successor Trustee under the Indenture).  Reference is hereby made to the Indenture for a description of the properties thereby mortgaged, pledged and assigned, the nature and extent of the security, the respective rights thereunder of the Holders of the Bonds, the Trustee and the Company, and the terms upon which the Bonds are, and are to be, authenticated and delivered.  All capitalized terms used in this Bond which are not defined herein shall have the respective meanings ascribed thereto in the Indenture.  Reference is also made to the Bond Purchase Agreements, as defined in the Sixth Supplemental Indenture, for a further description of the respective rights of the Holders of the Series G Bonds, the Company and the Trustee, and the terms applicable to the Series G Bonds.



As provided in the Indenture, the Bonds are issuable in series which may vary as in the Indenture provided or permitted.  This Bond is one of the series specified in its title.



The Bonds are not subject to any sinking fund or mandatory scheduled redemption prior to final maturity.



As provided in the Indenture, at the option of the Company, the Series G Bonds shall be redeemable in whole at any time or in part from time to time, prior to their Stated Maturity, at a redemption price equal to the principal amount of the Series G Bonds being prepaid plus accrued interest thereon to the date of such redemption together with a premium equal to the then applicable Make-Whole Amount.



The Company will give notice of any optional redemption of the Series G Bonds pursuant to Section 2.03 of the Sixth Supplemental Indenture to each Holder thereof not less than 30 days nor more than 60 days before the date fixed for such optional redemption, specifying (a) such date, (b) the principal amount of the Holder's Bond to be redeemed on such date, (c) that a premium may be payable, (d) the estimated premium, calculated as of the day such notice is given and (e) the accrued interest applicable to the redemption.  Such notice of redemption shall also certify all facts, if any, which are conditions precedent to any such redemption.  Notice of redemption having been so given, the aggregate principal amount of the Series G Bonds specified in such notice, together with accrued interest thereon, and the premium, if any, payable with respect thereto shall become due and payable on the redemption date specified in such notice.  Two business days prior to the redemption date specified in such notice of optional redemption, the Company shall provide the Trustee and each Holder of a Bond written notice of whether or not any premium is payable in connection with such redemption, the premium, if any, calculated as of the second business day prior to the redemption date, and a reasonably detailed computation of the Make-Whole Amount.



Bonds (or portions thereof) for whose redemption and payment provision is made in accordance with the Indenture shall thereupon cease to be entitled to the lien of the Indenture and shall cease to bear interest from and after the date fixed for redemption (in each event, so long as the payment due on any such date shall be made).  The principal amount of the Series G Bonds to be redeemed upon any optional redemption thereof shall be applied pro rata to all such Series G Bonds Outstanding on the Redemption Date.



If an Event of Default, as defined in the Indenture, shall occur, the principal of the Series G Bonds may become or be declared due and payable in the manner and with the effect provided in the Indenture and the Bond Purchase Agreements.



The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Bonds under the Indenture at any time by the Company with the consent of the Holders of a majority in aggregate principal amount of the Bonds of all series at the time Outstanding affected by such modification.
