The principal amount of the Bonds of the 7.28% 2016 Series shall be and hereby is limited, except for duplicate Bonds authenticated and delivered pursuant to Section 3.12 of the Original Indenture, to Ten Million Dollars ($10,000,000) in aggregate principal amount. The definitive Bonds of the 7.28% 2016 Series shall be issued only as registered Bonds without coupons of the denomination of $1,000 or any integral multiple thereof. All Bonds of the 7.28% 2016 Series shall mature December 1, 2016, and shall bear interest at the rate of 7.28% per annum until payment of the principal thereof, such interest to be payable semi-annually, on June 1 and December 1 in each year, and shall bear interest at the rate of 8.28% per annum on any overdue payment of principal and, so far as the same may be legally enforceable, on any overdue payment of interest or premium, until the same shall be paid in full, such interest on any such overdue payment to be payable on demand. Interest on the Bonds shall be computed on the basis of a 360-day year of twelve 30-day months. The principal of, the premium, if any, and interest on, the Bonds of the 7.28% 2016 Series shall be paid in any coin or currency of the United States of America which at the time of payment is legal tender for the payment of public and private debts, at the principal corporate trust office of the Trustee in the City of Boston, Commonwealth of Massachusetts; provided, however, that, subject to any applicable direct payment provisions, interest on the Bonds of the 7.28% 2016 Series may be paid by checks payable to the order of the respective holders entitled thereto and mailed by the Trustee by first class mail, postage prepaid, to such holders at their respective registered addresses as shown on the Bond register for the Bonds of the 7.28% 2016 Series.

The term "record date" as used in this Section 1.01, and in the form of the Bonds of the 7.28% 2016 Series, with respect to any interest payment date applicable to the Bonds of the 7.28% 2016 Series, shall mean the May 15 next preceding a June 1 interest payment date or the November 15 next preceding a December 1 interest payment date, as the case may be, or such record date established for defaulted interest as hereinafter provided.

Such provision for establishment of a subsequent record date, however, shall in no way affect the rights of bondholders or of the Trustee consequent on any default. Every Bond of the 7.28% 2016 Series shall be dated as provided in Section 3.05 of the Original Indenture, except that, so long as there is no existing default in the payment of interest on the Bonds of the 7.28% 2016 Series, all Bonds of the 7.28% 2016 Series authenticated by the Trustee between the record date for any interest payment date and such interest payment date shall be dated such interest payment date and shall bear interest from such interest payment date; provided, however, that if and to the extent that the Company shall default in the payment of the interest due on such interest payment date, then any such Bond of the 7.28% 2016 Series shall bear interest from the June 1 or December 1, as the case may be, to which interest has been paid, unless such interest payment date is June 1, 1997, in which case such Bond shall bear interest from the date of authentication upon original issue of such Bond. Any notice affecting or relating to the Bonds of the 7.28% 2016 Series required or permitted to be given under the Indenture may be given by mailing the same by nationally recognized overnight mail or delivery service, at the expense of the sender, to the holders of record at the date of mailing at their respective addresses as shown on the Bond register for the Bonds of the 7.28% 2016 Series.

The bonds of this series are subject to mandatory redemption prior to maturity as a whole at any time or in part from time to time, by operation of the sinking fund provided for in the Fifteenth Supplemental Indenture at 100% of the principal amount thereof, all in accordance with the terms of the Indenture. In addition, the Company shall have the right, at its option (an "Optional Redemption"), exercisable at any time and from time to time, of paying the outstanding bonds of this series, either in whole or in part (but if in part, then in units in excess of $100,000) by payment of the principal amount of the bonds of this series, or portion thereof to be redeemed, and accrued interest thereon to the date of such redemption, together with a premium equal to the Make-Whole Premium (determined three business days prior to the date of redemption). Notice of an Optional Redemption shall be given by nationally recognized overnight mail or delivery service, at the expense of the sender, to the holder of record of each bond affected and subject to all other conditions and provisions of the Indenture, not less than thirty days nor more than ninety days prior to the date fixed for redemption. Three business days prior to the date specified in such notice for such Optional Redemption, the Company shall provide each holder of the Bonds of this series written notice (by telecopy transmission and overnight mail or delivery service) of the Make-Whole Premium payable in connection with such Optional Redemption, determined as of such date, together with a reasonably detailed computation thereof. The Trustee shall have no obligation to calculate or verify any calculation of the Make- Whole Premium. As used herein, the following terms shall be defined as follows: "Make-Whole Premium" shall mean, in connection with the above described Optional Redemption, the excess, if any, of (i) the aggregate present value as of the date of such redemption of each dollar of principal being paid (taking into account the application of such Optional Redemption required by Section 1.03 of the Fifteenth Supplemental Indenture) 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 Optional 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 (ii) 100% of the principal amount of the outstanding bonds of this series being redeemed. If the Reinvestment Rate is equal to or higher than 7.28%, the Make-Whole Premium shall be zero. "Reinvestment Rate" shall mean .50% plus the yield to maturity implied by the yields reported, as of 10:00 A.M. (New York City time) on the third business day next preceding the date upon which payment of principal is required hereunder with respect to the outstanding principal amount of the Bonds of this series to be paid, on the display designated as "USD" of the Bloomberg Financial Markets Services Screen (or such other display as may replace page "USD" of the Bloomberg Financial Markets Services Screen) for actively traded U.S. Treasury securities having a maturity equal to the Weighted Average Life to Maturity of such outstanding principal as of such date upon which the payment of principal is required hereunder (taking into account the application of such Optional Redemption required by Section 1.03 of the Fifteenth Supplemental Indenture). If no such published 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 or, if no month is nearest, rounding up to the greater number of months. For the purposes of calculating the Reinvestment Rate, the most recent Statistical Release published prior to the date of determination of the premium hereunder shall be used. "Statistical Release" shall mean the 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 U.S. 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 bonds of this series. "Weighted Average Life to Maturity" of the principal amount of the bonds of this series being optionally 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 (i) multiplying (1) the remainder of (A) the amount of principal that would have become due on each scheduled sinking fund payment date if such Optional Redemption had not been made, less (B) the amount of principal on the bonds of this series scheduled to become due on such date after giving effect to such Optional Redemption and the application thereof in accordance with the provisions of Section 1.03 of the Fifteenth Supplemental Indenture, by (2) the number of years (calculated to the nearest one-twelfth) which will elapse between the date of determination and such scheduled payment date, and (ii) totaling the products obtained in (i). If this bond or any portion hereof ($100,000 or any integral multiple hereof) is duly designated for redemption, if payment of the principal hereof or of such portion together with accrued interest and premium, if any, is irrevocably provided for, and if notice of such redemption is duly given or provided for, all as specified in the Indenture, this bond or such portion shall cease to be entitled to the lien of the Indenture from and after the date such payment and notice are irrevocably so provided for and shall cease to bear interest from and after the date fixed for redemption. Except as may be otherwise provided in any agreement entered into pursuant to the provisions of the Indenture, in the event of the selection for redemption of a portion only of the principal of this bond, payment of the redemption price will be made at the option of the registered owner, either (a) upon presentation of this bond for notation hereon of such payment of the portion of the principal of this bond so called for redemption, or (b) upon surrender of this bond in exchange for a bond or bonds, of authorized denominations of the same series, for the unredeemed balance of the principal amount of this bond. In the event of the redemption of this bond in whole, payment of the redemption price will be made only upon surrender of this bond. The Indenture contains provisions permitting the Company and the Trustee, with the consent of the holders of not less than sixty-six and two-thirds per cent in principal amount of the bonds at the time outstanding (determined as provided in the Indenture) including, if more than one series of bonds shall be at the time outstanding, not less than sixty-six and two-thirds per cent in principal amount of the bonds at the time outstanding of each series affected, to effect, by an indenture supplemental to the Indenture, modifications or alterations of the Indenture and of the rights and obligations of the Company and of the holders of the bonds and coupons; provided, however, that no such modification or alteration shall be made without the consent of the registered owner hereof which will (a) extend the maturity of this bond or reduce the rate or extend or otherwise change the time of payment of interest hereon or reduce the amount of the principal hereof or reduce any premium payable on the redemption hereof, or (b) permit the creation of any lien, not otherwise permitted, prior to or on a parity with the lien of the Indenture, or alter the equal and proportionate security afforded by the lien of the Indenture for the bonds issued thereunder, or (c) reduce the number or percentage of the principal amount of the bonds upon the consent of the holders of which modifications or alterations may be made as aforesaid or defaults may be waived. The Company and the Trustee, any paying agent and any bond registrar may deem and treat the person in whose name this bond is registered upon the bond register for the bonds of this series as the absolute owner of such bond for the purpose of receiving payment of or on account of the principal of, the premium, if any, and interest on this bond and for all other purposes, whether or not this bond be overdue, and neither the Company nor the Trustee nor any paying agent nor any bond registrar shall be affected by any notice to the contrary; and all such payments so made to such registered owner or upon his order shall be valid and effectual to satisfy and discharge the liability upon this bond to the extent of the sum or sums so paid. This bond is transferable by the registered owner hereof in person or by his duly authorized attorney, on the books of the Company kept for the purpose, at the principal corporate trust office of the Trustee upon surrender of this bond for cancellation and upon payment, if the Company shall so require, of the charges provided for in the Indenture, and thereupon a new registered bond of the same series of like principal amount will be issued to the transferee in exchange therefor. The registered owner of this bond at his option may surrender the same for cancellation at said office and receive in exchange therefor the same aggregate principal amount of registered bonds of the same series but of other authorized denominations, upon payment, if the Company shall so require, of the charges provided for in the Indenture and subject to the terms and conditions therein set forth. Neither the Company nor the Trustee shall be required to make transfers or exchanges of bonds of this series for a period of ten days next preceding any designation of bonds of said series to be redeemed, and neither the Company nor the Trustee shall be required to make transfers or exchanges of any bonds designated in whole for redemption or that part of any bond designated in part for redemption. Subject to the provisions of the Fifteenth Supplemental Indenture, if this bond is surrendered for any transfer or exchange between the record date for any regular interest payment date and such interest payment date, the new bond will be dated such interest payment date. If this bond is surrendered for any transfer or exchange between such record date and such interest payment date, the Fifteenth Supplemental Indenture provides that in the event of any default in payment of the interest due on such payment date, such interest shall not be payable to the holder of the bond on the original record date but shall be paid to the registered holder of such bond on the subsequent record date established for payment of such defaulted interest. If a default as defined in the Indenture shall occur, the principal of this bond may become or be declared due and payable before maturity in the manner and with the effect provided in the Indenture. The holders, however, of certain specified percentages of the bonds at the time outstanding, including in certain cases specified percentages of bonds of particular series, may in these cases, to the extent and under the conditions provided in the Indenture, waive past defaults thereunder and the consequences of such defaults. No recourse shall be had for the payment of the principal of or premium, if any, or the interest on this bond, or for any claim based hereon, or otherwise in respect hereof or of the Indenture, against any incorporator, stockholder, director or officer, past, present or future, as such, of the Company or of any predecessor or successor corporation, either directly or through the Company or such predecessor or successor corporation, under any constitution or statute or rule of law, or by the enforcement of any assessment or penalty, or otherwise, all such liability of incorporators, stockholders, directors and officers, as such, being waived and released by the holder and owner hereof by the acceptance of this bond and as provided in the Indenture.

Section 1.02. Redemption Provisions for Bonds of the 7.28% 2016 Series. The Bonds of the 7.28% 2016 Series shall be subject to redemption prior to maturity as a whole at any time or in part (but if in part, then in units in excess of $100,000) from time to time, (a) at the option of the Company upon payment of the Make-Whole Premium, if any; and (b) upon payment of the called principal amount thereof, (I) through the application of cash deposited with the Trustee for the sinking fund for the Bonds of said series provided for in Section 1.03 hereof, or (ii) inn the case of an Optional Redemption, through the application of cash deposited with the Trustee for such purpose, or (iii) through the application pursuant to Section 8.05 of the Original Indenture of any trust moneys held by the Trustee received from (a) the proceeds of property sold or taken pursuant to the provisions of Section 7.04 of the Original Indenture or (b) the proceeds of insurance not applied or required to be applied to the repair, restoration or replacement of the property destroyed or damaged or to other additions to the trust estate pursuant to the provisions of Section 9.09 and Article Eight of the Original Indenture, provided, however, that if more than one series of Bonds is at the time outstanding, such trust moneys referred to in this clause (ii) shall be applied, as to the Bonds of the 7.28% 2016 Series, as nearly as may be in the proportion that the aggregate principal amount of the outstanding Bonds of the 7.28% 2016 Series bears to the aggregate principal amount of the Bonds of all series then outstanding; together in any case with interest accrued thereon to the date fixed for redemption, upon not less than thirty nor more than ninety days notice given by nationally recognized overnight mail or delivery service, at the expense of the sender, to the holders of record at the date of mailing of such notice of each Bond of the 7.28% 2016 Series affected, at his address as shown on the Bond register for Bonds of the 7.28% 2016 Series. Such notice shall comply with the requirements of Sections 2.07 and 10.02 of the Original Indenture. In addition to the foregoing, in the event that the Company elects to make an Optional Redemption, three business days prior to the date of such Optional Redemption, as specified in the notice given pursuant to Sections 2.07 and 10.02 of the Original Indenture, the Company shall provide each holder of the Bonds of the 7.28% 2016 Series written notice (by telecopy transmission and overnight mail or delivery service) of the Make-Whole Premium payable in connection with such Optional Redemption, as of such date, together with a reasonably detailed computation thereof. The Trustee shall have no obligation to calculate or verify any calculation of the Make- Whole Premium. Notwithstanding the provisions of the Original Indenture (including, without limitation, Section 10.03 thereof), whenever less than all the outstanding Bonds of the 7.28% 2016 Series are to be redeemed, whether at the option of the Company or through the operation of the sinking fund or otherwise, the principal amount of such Bonds to be redeemed shall be prorated in units of $1,000 among the holders of the Bonds of the 7.28% 2016 Series in the proportions that their respective holdings bear to the aggregate principal amount of Bonds of the 7.28% 2016 Series outstanding on the date of selection. In case any holder of two or more registered Bonds of the 7.28% 2016 Series shall so request in writing filed with the Trustee, the Trustee, until further notice from said holder, shall, for the purposes of proration as aforesaid, treat each such registered Bond held by said holder as if it were held by a separate and distinct holder. The principal of pro rata redemption provided for herein shall be maintained in successive partial redemptions, as well as in any single partial redemption, so that, so far as practicable, at all times the aggregate principal amount of Bonds of the 7.28% 2016 Series registered in the name of any holder which have been redeemed shall be equal to the principal amount of Bonds of the 7.28% 2016 Series registered in the name of such holder which would have been redeemed if redemptions in multiples of $1,000 were not required. Such allocations as may be requisite for the purposes of the two next preceding sentences shall be made by the Trustee in its uncontrolled discretion. Section 1.03. Sinking Fund for Bonds of the 7.28% 2016 Series. As a sinking fund for the benefit of the Bonds of the 7.28% 2016 Series, the Company covenants that it will, on or before November 30, in each year, beginning November 30, 2006, and continuing to and including November 30, 2016, pay to the Trustee cash sufficient to redeem on the next succeeding December 1 at 100% of the principal amount thereof, Bonds of the 7.28% 2016 Series then outstanding, in the principal amount of $909,091 or the then aggregate principal amount of the outstanding Bonds of the 7.28% 2016 Series, if less than such amount. The payments and the dates upon which payments are required for the sinking fund as above provided are in this Section 1.03 and in the annual sinking fund certificate hereinafter provided for referred to as "mandatory sinking fund payments" and "sinking fund payment dates," respectively. No partial redemption of the Bonds of the 7.28% 2016 Series (including, specifically, the optional and other redemptions contemplated by Section 1.02) shall relieve the Company of its obligation to pay mandatory sinking fund payments. The Company shall file with the Trustee on or before the October 15 next preceding any sinking fund payment date an officers' certificate (herein referred to as an "annual sinking fund certificate"), substantially in the following form: Essex County Gas Company (formerly known as Haverhill Gas Company) Indenture Dated as of October 1, 1955, as Supplemented By a Fifteenth Supplemental Indenture Dated as of December 1, 1996 ____________________________ Annual Sinking Fund Certificate The undersigned, one of whom is an accountant, in compliance with the provisions for a sinking fund contained in Section 1.03 of the above-mentioned Fifteenth Supplemental Indenture (hereinafter called the "Fifteenth Supplemental Indenture") supplementing the above-mentioned Indenture (hereinafter called the "Original Indenture"), do hereby certify as follows: 1. The amount of the mandatory cash sinking fund payment due on November 30, ____ (here there should be specified the November 30 next succeeding the date of filing of the certificate) as provided in Section 1.03 of the Fifteenth Supplemental Indenture, is $________________. 2. The Company is not in default in the performance of any covenant, agreement or condition contained in the Original Indenture, as supplemented (provided, that in the event the Company is in default, this paragraph 2 shall describe such default and the actions the Company is taking to cure such default). [Here insert statements required by Section 2.04 of the Original Indenture.] Dated: ___________________ ______________________________________ President ______________________________________ Treasurer of Essex County Gas Company All Bonds of the 7.28% 2016 Series redeemed by operation of the sinking fund, shall be deemed to be thereupon funded, but only so long as any Bonds of the 7.28% 2016 Series are outstanding. All Bonds of the 7.28% 2016 Series so redeemed shall, if not previously cancelled, be forthwith cancelled by the Trustee. Forthwith after the October 15 preceding each sinking fund payment date, the Trustee shall proceed to select for redemption, in the manner provided in the last paragraph of Section 1.02 of this Fifteenth Supplemental Indenture, a principal amount of Bonds of the 7.28% 2016 Series equal to the amount of the mandatory sinking fund payment required at such date and, in the name of the Company, shall give notice as required by the provisions of Section 1.02 of this Fifteenth Supplemental Indenture and Article Ten of the Original Indenture, of the redemption for the sinking fund on the then next ensuing December 1, of the Bonds so selected. On or before the sinking fund payment date next preceding such December 1, the Company shall pay to the Trustee the mandatory sinking fund payment required by this Section, plus the amount of all interest accrued on Bonds of the 7.28% 2016 Series to be redeemed by the application of such cash payments, and the money so paid shall be applied by the Trustee to the redemption of such Bonds. All cash paid to the Trustee pursuant to the provisions of this Section 1.03 or pursuant to the provisions of Section 1.02 above, shall be held by the Trustee as security for the payment of the Bonds of the 7.28% 2016 Series until applied as herein or therein provided. The Company, upon request of the Trustee from time to time, will pay to the Trustee an amount equal to the cost of giving notice of redemption of Bonds of the 7.28% 2016 Series for such sinking fund, for giving notice of any Optional Redemption and any other expense of operation of such sinking fund, the intention being that such fund shall not be charged for such expenses. Section 1.04. Restriction on Payment of Dividends on Common Stock;. The Company shall not directly or indirectly (a) declare or pay any dividend (other than dividends payable in Common Stock of the Company) or declare or make any other distribution on any shares of Common Stock, or (b) make any expenditures for the purchase, redemption or other retirement for a consideration of any shares of capital stock of the Company (other than in exchange for, or from the net cash proceeds of, other and new shares of capital stock of the Company and other than any shares of any class of stock required to be purchased, redeemed or otherwise retired for any sinking fund or purchase fund for such class of stock), if the aggregate amount of all such dividends, distributions and expenditures made since August 31, 1996 would exceed the aggregate amount of the net income of the Company accumulated after August 31, 1996 plus the sum of $4,000,000. Net income of the Company for the purpose of this Section shall mean the sum of (a) the total operating revenues of the Company, less an amount equal to the total operating expenses of the Company, including but not limited to (i) all taxes (including without limitation income, excess profits and other taxes imposed on or measured by income or undistributed earnings or income), (ii) rentals, insurance, current repairs and maintenance, (iii) provision for retirements, depreciation or obsolescence, which shall be the amount actually charged by the Company on its books of account (but in respect of depreciable gas utility property not subject to prior liens shall not be less than the minimum provision for depreciation as defined in Section 1.05 of this Fifteenth Supplemental Indenture), and (iv) all charges on account of interest on indebtedness and on account of debt discount and expense, and (b) net income or loss from the operation of properties other than the trust estate and any other income received (less applicable expenses) or loss incurred by the Company; which sum shall be diminished by an amount equal to all dividends accrued (whether or not paid) on any outstanding stock of the Company having preference over the Common Stock as to dividends, assets or otherwise, all of the foregoing determined in accordance with sound accounting practice. In determining the net income of the Company for the purpose of this Section, no deduction or adjustment shall be made for or in respect of any charges or credits which under sound accounting practice are not appropriate charges or credits in determining net income and, without limiting the generality of the foregoing, the following items shall be excluded from the computation: (1) expenses in connection with the issuance of stock of the Company and expenses in connection with the redemption or retirement of any securities issued by the Company, including any amount paid in excess of the principal amount or par or stated value of securities redeemed or retired, or, in the event that such redemption or retirement is effected with the proceeds of sale of other securities of the Company, any interest or dividends on the securities redeemed or retired from the date on which the funds required for such redemption or retirement are deposited in trust for such purpose to the date of redemption or retirement; (2) profits or losses from the sale, abandonment or other disposition of property or other assets carried in plant or investment accounts of the Company, or from the reacquisition of any securities of the Company, or taxes in respect of any such profits or reduction of taxes in respect of any such losses; (3) any change in or adjustment of the book value of any assets owned by the Company arising from a revaluation thereof; (4) any adjustment (including tax adjustments) applicable to any period prior to January 1, 1973; or (5) amortization or elimination of gas utility property, plant adjustment or acquisition accounts or intangibles.

Section 1.06. Compliance with Laws;. The Company shall conduct its operations and keep and maintain its property in compliance with all Environmental Legal Requirements and shall obtain all necessary governmental permits, approvals, licenses and consents ("Environmental Permits") to the extent that non- compliance with such Environmental Legal Requirements or failure to obtain such Environmental Permits will have a material adverse effect, and solely with respect to non-compliance with governmental orders or directives issued pursuant to Environmental Legal Requirements, the Company has diligently applied for and obtained Environmental Permits necessary to effect such compliance, and such non-compliance continues for more than 180 days after the Environmental Permits have issued and become effective; provided, however, that nothing contained in this Section shall prevent the Company from contesting, in good faith by appropriate legal proceedings, any Environmental Legal Requirements, the interpretation thereof or the application thereof, or the necessity or applicability of any Environmental Permit, provided, further, that the Company shall comply with the order of any court or other governmental body of applicable jurisdiction relating to such laws unless the Company shall currently be prosecuting an appeal or proceedings for review and shall have secured a stay of enforcement or execution or other arrangement, postponing, enforcement or execution pending such appeal or proceedings for review. For purposes of this Section 1.06, the term "Environmental Legal Requirements" shall mean any applicable law relating to public health, safety or the environment, including, without limitation, relating to releases, discharges or emissions to air, water, land or groundwater, to the withdrawal or use of groundwater, to the use and handling of polychlorinated byphenyls or asbestos, to the disposal, treatment, storage or management of solid or hazardous wastes or to exposure to toxic or hazardous materials, to the handling, transportation, discharge or release of gaseous or liquid substances and any regulation, order, notice or demand issued pursuant to such statute or ordinance, in each case applicable to the property or assets of the Company or the operation, construction or modification of any thereof, including without limitation the following: the Clear Air Act, the Federal Water Pollution Control Act, the Safe Drinking Act, the Toxic Substances Control Act, the Comprehensive Environmental Response Compensation and Liability Act as amended by the Superfund Amendments and Reauthorization Act of 1986, the Resource Conservation and Recovery Act as amended by the Solid and Hazardous Waste Amendments of 1984, the Occupational Safety and Health Act, the Emergency Planning and Community Right-to-Know Act of 1986, the Solid Waste Disposal Act, and any state statutes addressing similar matters, and any state statute providing for financial responsibility for cleanup or other actions with respect to the release or threatened release of hazardous substances and any state nuisance statute.

Section 2.02. Bonds of the 7.28% 2016 Series in the aggregate principal amount of Ten Million Dollars ($10,000,000) may forthwith, upon the execution and delivery of this Fifteenth Supplemental Indenture, or from time to time thereafter, and upon compliance by the Company with the provisions of Sections 5.02 and 5.03 of the Original Indenture, be executed by the Company and delivered to the Trustee and shall thereupon be authenticated and delivered by the Trustee to or upon the written order of the Company. Article Three Certain Definitions As used in this Fifteenth Supplemental Indenture, the following terms shall be defined as follows: "Make-Whole Premium" shall mean, in connection with an Optional Redemption of the Bonds of the 7.28% 2016 Series, the excess, if any, of (i) the aggregate present value as of the date of such redemption of each dollar of principal being paid (taking into account the application of such Optional Redemption required by Section 1.03 of the Fifteenth Supplemental Indenture) 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 Optional 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 (ii) 100% of the principal amount of the Bonds of the 7.28% 2016 Series being redeemed. If the Reinvestment Rate is equal to or higher than 7.28%, the Make-Whole Premium shall be zero. "Reinvestment Rate" shall mean .50% plus the yield to maturity implied by the yields reported, as of 10:00 A.M. (New York City time) on the third business day next preceding the date upon which payment of principal is required hereunder with respect to the outstanding principal amount of the Bonds of the 7.28% 2016 Series to be paid, on the display designated as "USD" of the Bloomberg Financial Markets Services Screen (or such other display as may replace page "USD" of the Bloomberg Financial Markets Services Screen) for actively traded U.S. Treasury securities having a maturity equal to the Weighted Average Life to Maturity of such outstanding principal as of such date upon which the payment of principal is required hereunder (taking into account the application of such Optional Redemption required by Section 1.03 of the Fifteenth Supplemental Indenture). If no such published 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 the purposes of calculating the Reinvestment Rate, the most recent Statistical Release published prior to the date of determination of the premium hereunder shall be used. "Statistical Release" shall mean the 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 U.S. 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 Bonds of the 7.28% 2016 Series. "Weighted Average Life to Maturity" of the principal amount of the Bonds of the 7.28% 2016 Series being optionally 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 (i) multiplying (1) the remainder of (A) the amount of principal that would have become due on each scheduled sinking fund payment date if such Optional Redemption had not been made, less (B) the amount of principal of the Bonds of the 7.28% 2016 Series scheduled to become due on such date after giving effect to such Optional Redemption and the application thereof in accordance with the provisions of Section 1.03 of the Fifteenth Supplemental Indenture, by (2) the number of years (calculated to the nearest one-twelfth) which will elapse between the date of determination and such scheduled payment date, and (ii) totaling the products obtained in (i). Article Four Miscellaneous Section 4.01. For the purpose of the last paragraph of Section 12.01 of the Indenture, the rate of interest referred to therein for the Bonds of the 7.28% 2016 Series is seven and twenty-eight one-hundredths percent (7.28%) per annum. Section 4.02. This Fifteenth Supplemental Indenture is executed and shall be construed as an indenture supplemental to the Original Indenture, and shall form a part thereof, and the Original Indenture as heretofore supplemented and modified and hereby supplemented is hereby confirmed. Except to the extent inconsistent with the express terms hereof, all of the provisions, terms, covenants and conditions of the Original Indenture shall be applicable to the Bonds of the 7.28% 2016 Series to the same extent as if specifically set forth herein. All terms used in this Fifteenth Supplemental Indenture shall be taken to have the same meaning as in the Original Indenture as heretofore supplemented and modified except in cases where the context clearly indicates otherwise.

The Company covenants that it is lawfully seized and possessed at the date of execution of this Fifteenth Supplemental Indenture of all the trust estate described in this Fifteenth Supplemental Indenture, except as specifically otherwise stated in this Fifteenth Supplemental Indenture, and that all the trust estate so described is free and clear of any lien other than the lien of the Indenture and permitted encumbrances; that the Company will warrant and forever defend all the trust estate so described to the Trustee against the claims of all persons whosoever except as in the Indenture specifically otherwise stated, that it will maintain and preserve the lien of the Indenture so long as any of the Bonds issued under the Indenture are outstanding; and that it has good right and lawful authority to subject all the trust estate so described to the lien of the Indenture as provided in and by the Original Indenture as heretofore supplemented and modified and as supplemented by this Fifteenth Supplemental Indenture. Section 4.05. This Fifteenth Supplemental Indenture may be executed in several counterparts, and each of such counterparts shall for all purposes be deemed to be an original, and all such counterparts, or as many of them as the Company and the Trustee shall preserve undestroyed, shall together constitute but one and the same instrument.
