The interest so payable on any June 30 or December 30 will, subject to certain exceptions provided in the Eighteenth Supplemental Indenture hereinafter referred to, be paid to the person in whose name this bond is registered at the close of business on the June 15 prior to such June 30 or the December 15 prior to such December 30, unless such June 15 or December 15 shall not be a business day, in which event on the next succeeding business day, the term "BUSINESS DAY" meaning for this purpose a day which in the City of Boston is not a legal holiday or a day on which banking institutions in the City of Boston are not authorized by law to close.

This bond shall not be valid or become obligatory for any purpose or entitled to any security or benefit under the Indenture (as hereinafter defined) unless or until the certificate endorsed hereon shall have been executed by the Trustee under the Indenture. This bond is one of a duly authorized issue of First Mortgage Bonds of the Company to be issued in series with distinctive designations, the series of which this bond is one being designated as Series K and limited to an aggregate principal amount of thirty-five million dollars ($35,000,000), which issue of bonds together with all other series which may now or hereafter be outstanding are issued and are to be issued under and equally and ratably secured by a certain Indenture of Trust and First Mortgage dated as of February 1, 1949 (hereinafter, with all indentures stated to be supplemental thereto, including an Eighteenth Supplemental Indenture dated as of December 1, 1993, to which the Trustee is a party, called the "INDENTURE") by and between the Company and State Street Trust Company (now known as State Street Bank and Trust Company) as Trustee, to which Indenture reference is hereby made for a description of the mortgaged property, the nature and extent of the security, the terms and conditions under which the bonds of Series K are issued and under which bonds of any subsequent series may be issued, the rights and limitations of the rights of the bondholders and the rights and obligations of the Company and the rights, duties and immunities of the Trustee. Subject to certain conditions and restrictions, additional first mortgage bonds of one or more series, equally and ratably secured by the Indenture, may be issued under the Indenture. This bond shall be treated as negotiable, subject to the provisions for registration and transfer herein and in the Indenture contained, and the Company and the registered owner hereof and every successive owner and assignee of this bond, by accepting and holding the same, consent to the foregoing provisions and each invites the others, and all persons, to rely thereon. The bonds of Series K are issuable only as fully registered bonds without coupons in denominations of one-hundred thousand dollars ($100,000) or integral multiples thereof. The holder of any Series K bond or bonds, may, upon payment of the charges and subject to the conditions specified in the Indenture, exchange the same at the principal corporate trust office of the Trustee in the City of Boston, Massachusetts for a like aggregate principal amount of fully registered Series K bonds of different authorized denominations, PROVIDED, HOWEVER, that the Company and the Trustee shall not be required (i) to transfer or exchange any bond of Series K during a period beginning at the opening of business fifteen (15) days before the day of the mailing of a notice of redemption of bonds of Series K and ending at the close of business on the day of such mailing or (ii) to transfer or exchange any bond of Series K so selected for redemption in whole or in part. As provided in the Eighteenth Supplemental Indenture, this bond shall be subject to redemption (i) at par, upon the concurrent payment of accrued interest and the Make-Whole Amount (as defined in the Eighteenth Supplemental Indenture), at the option of the Company, and (ii) at par, upon the concurrent payment of accrued interest, under certain circumstances from the proceeds of insurance for casualty or from the proceeds of taking by or sale to a public authority. If this bond is called for redemption in whole or in part and payment is duly provided as specified in the Indenture, this bond, or the part thereof so called, shall cease to be entitled to the security of the Indenture, and from and after the date fixed in the call for such redemption, interest shall cease to accrue on this bond, or on such part so called; and if less than the whole principal amount hereof shall be called, the registered owner hereof shall, in PAGE 6 addition to the sums payable on account of the part called, be entitled, at his option, to receive on surrender hereof one or more bonds of this series, of an aggregate principal amount equal to that part of the principal amount hereof not called and paid, or to present this bond for the notation hereon by the Trustee (or to make such notation in accordance with an agreement for payment of principal filed with the Trustee as provided in this bond) of the payment of the part of the principal amount hereof then called and paid. The principal hereof may be declared and become due prior to maturity in case of certain events of default specified in the Indenture. The Indenture may be modified and amended in certain respects upon the conditions and in the manner provided therein, if such modification is approved and authorized by the Board of Directors of the Company and approved by the holders of not less than a majority in principal amount of the bonds then outstanding; PROVIDED, HOWEVER, that no such amendment or modification shall (i) extend the time of payment of the principal, premium, if any, or interest on this bond or change the principal amount, premium, if any, or rate of interest payable on this bond or affect or impair the obligations of the Company in respect of the principal or interest of this bond without the written consent of the holder hereof, (ii) permit the creation by the Company of any lien ranking prior to or on a parity with the lien of the Indenture with respect to any property covered thereby, (iii) affect the rights of any series of bonds in a manner differing from that of any other series except with the consent, given as provided in the Indenture, of the owners of not less than 66-2/3% in principal amount of the outstanding bonds of each series so affected, (iv) change the percentages of the holders of bonds required for any action or consent under the Indenture without the consent of the holders of all of the bonds then outstanding, or (v) modify the rights, duties or immunities of the Trustee without its written consent. The Company and the Trustee may, without action or consent by or notice to the bondholders, enter into supplemental indentures for the purposes of conveying additional property, adding further limitations upon the issuance of additional bonds, setting forth the form of additional bonds and the terms not inconsistent with the Indenture under which they may be issued, establishing a successor trustee, modifying the Indenture or the form of any bonds or coupons in a manner not prejudicial to holders in order to facilitate listing of such outstanding bonds on any stock exchange, curing ambiguities or remedying defects or manifest errors in the Indenture or a supplemental indenture, or for any other purpose not inconsistent with and not impairing the benefits of the Indenture. Any consent or waiver by the holder of this bond as aforesaid shall be conclusive and binding upon such holder and upon all future holders and registered owners of this bond or of any other bond issued in lieu hereof or in substitution hereof (unless effectively revoked, as provided in the Indenture) whether or not any notation of such consent or waiver is made upon this bond. This bond is transferable on the books of the Company at said principal corporate trust office, upon surrender hereof, accompanied by a written instrument of transfer in form satisfactory to the Trustee, duly executed by the registered owner hereof in person or by his duly authorized representative, or by his agent or attorney duly appointed in writing, and thereupon a new fully registered bond or fully registered bonds of authorized denominations of the same series for a like principal amount will be issued to the transferee or transferees in exchange for this bond. The Company, the Trustee, and any paying agents and registrars may deem and treat the person in whose name this bond is registered as the absolute owner for the purpose of receiving payment and for all other purposes. No recourse upon any obligation contained in this bond or in the Indenture or otherwise shall be had against any incorporator or any officer, director or stockholder, past, present or future, of the Company or of any successor corporation, such personal liability of every kind being expressly waived.

And the Company for itself and its successors and assigns does hereby further covenant, agree and declare to and with the Trustee and its successors and assigns in said trust, for the benefit of said Series K Bonds, or any of them, as follows: ARTICLE I SECTION 1. There is hereby created and established under the Principal Indenture and hereunder a new series of bonds of the Company, limited in aggregate principal amount to thirty-five million dollars ($35,000,000), designated "FIRST MORTGAGE 7.11% BONDS, SERIES K, DUE 2033," which shall mature December 30, 2033, and shall bear interest at the rate of 7.11% per annum, payable semi-annually, on the thirtieth day of June and December in each year until the principal of the Series K Bonds shall have become due and payable (whether at maturity or at a date fixed for redemption or by declaration or otherwise), and with interest on any overdue principal (including any overdue prepayment of principal) and (to the extent permitted by applicable law) overdue premium, if any, and (to the extent permitted by applicable law) on any overdue installment of interest, at the rate of 9.11% per annum until paid, payable semi-annually as aforesaid, or, at the option of the registered owner of any Series K Bond, on demand. Forthwith upon and from PAGE 12 time to time after the execution and delivery of this Eighteenth Supplemental Indenture, the Company may execute and deliver to the Trustee and thereupon the Trustee shall certify and deliver to or upon the written order of the President or Treasurer of the Company, Series K Bonds to an aggregate principal amount not exceeding thirty-five million dollars ($35,000,000) in temporary or permanent form, being all the Series K Bonds authorized to be issued hereunder, upon receipt by the Trustee in each case of the Votes, Certificates, Opinions of Counsel, and a certified copy (or assurances satisfactory to the Trustee that there will be delivered to the Trustee, within a time deemed reasonable by it, a certified copy) of an order or orders of each governmental agency having jurisdiction releasing, exempting, authorizing or consenting to the issuance by the Company of a principal amount of said bonds at least equal to the principal amount of bonds the certification and delivery of which is requested by the written order or orders of the President or Treasurer of the Company, all as required by Section 2 of Article III of the Principal Indenture, as amended. SECTION 2. The bonds of Series K are issuable only as fully registered bonds without coupons in denominations of one-hundred thousand dollars ($100,000) or integral multiples thereof. Bonds of Series K may be transferred and may be exchanged for one or more bonds of the same series in authorized denominations, as provided in the Principal Indenture, PROVIDED, HOWEVER, that the Company and the Trustee shall not be required (i) to transfer or exchange any bond of Series K during a period beginning at the opening of business fifteen (15) days before the day of the mailing of a notice of redemption of bonds of Series K and ending at the close of business on the day of such mailing or (ii) to transfer or exchange any bond of Series K so selected for redemption in whole or in part. Notwithstanding any provisions of the Indenture or the Series K Bonds to the contrary, no service charge shall be made to the holder for any such transaction. Except as hereinafter provided, each bond of Series K shall be dated the date of certification and shall bear interest from the last preceding interest payment date to which interest has been paid (unless the date thereof is an interest payment date to which interest has been paid, in which case from the date thereof, or unless the date thereof is prior to the first payment of interest, in which case from the date of original issuance of the bonds of such series). The person in whose name any bond of Series K is registered at the close of business on the record date (hereinafter defined) with respect to a semi- annual interest payment date shall be entitled to receive the interest payable on such interest payment date notwithstanding the cancellation of such bond upon any transfer or exchange thereof subsequent to such record date and prior to such interest payment date; PROVIDED, HOWEVER, that if and to the extent the Company shall default in the payment of the interest due on such interest payment date, such defaulted interest, together with interest thereon at the rate set forth in Section 1 hereof to the extent permitted by applicable law, shall be paid to the person in whose name such bond is registered at the close of business on the business day immediately prior to the date of payment of such defaulted interest. The term "RECORD DATE" as used with respect to a semi-annual interest payment date shall mean the fifteenth day of the same calendar month of such interest payment date unless such day shall not be a business day, in which event the term "RECORD DATE" shall mean the next succeeding business day, the term "BUSINESS DAY" meaning for this purpose a day which in the City of Boston is not a legal holiday or a day on which banking institutions in the City of Boston are not authorized by law to close. Subject to the provisions of Section 4 of this Article I, the principal, premium, if any, and interest on the Series K Bonds shall be payable 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, Massachusetts, or, at the option of the registered owner, at the office of any other paying agent appointed by the Company. The Company may cause bonds of Series K to be executed on its behalf by the facsimile signatures of its President or a Vice President and its PAGE 13 Treasurer or an Assistant Treasurer, which may be imprinted or otherwise reproduced on such bonds, and may cause a facsimile of its official seal to be imprinted thereon. In case any officer whose facsimile signature has been so imprinted or otherwise reproduced on any bond of Series K shall cease to be such officer of the Company before such bond shall have been actually certified and delivered by the Trustee, such bond may nevertheless be certified and delivered and issued as though the person whose facsimile signature has been so imprinted or otherwise reproduced had not ceased to be an officer of the Company. SECTION 3. The provisions of the Series K bonds relating to redemption prior to maturity are as follows: A. The Company may redeem Series K Bonds at par, plus accrued interest, pursuant to Section 7(d) of Article VI of the Principal Indenture, but any such redemption of the Series K Bonds pursuant to such Section 7(d) of Article VI of the Principal Indenture shall be made (i) only from money received by the Trustee as proceeds of property taken by the power of eminent domain or acquired by public authority, or as insurance money, (ii) only in principal amounts of one-hundred thousand dollars ($100,000) or integral multiples thereof and (iii) only if such redemption pursuant to such Section 7(d) of Article VI of the Principal Indenture is made pro rata among all series of bonds then outstanding under the Principal Indenture in proportion to their then outstanding principal amounts, PROVIDED, HOWEVER, to the extent, but only to the extent, that such prorating would involve the redemption of the bonds of any series in any amount other than that permitted under the terms of the bonds of such series, the Trustee may upon any such redemption of such series, in its reasonable discretion, increase or decrease the amount of bonds of such series to be redeemed in such manner as the Trustee, in its reasonable discretion, shall deem appropriate to maintain, in so far as possible, the principal of pro rata redemption in any such redemption or in any series of successive redemptions. B. The Series K Bonds are redeemable prior to maturity at the option of the Company, as a whole at any time, or in part from time to time, in a minimum aggregate principal amount at any one time of not less than one million dollars ($1,000,000), PROVIDED, that not less than five million dollars ($5,000,000) in the aggregate principal amount of the Series K Bonds remains outstanding after giving effect to any such partial redemption, upon at least 30 days' but not more than 45 days' prior notice, as set forth below, at the principal amount of Series K Bonds so to be redeemed and accrued interest to the date fixed for redemption, together with a premium equal to the Make-Whole Amount (hereinafter defined) calculated as of three days prior to the date fixed for such redemption, PROVIDED, that the Company shall, on the second day preceding the date of any such redemption, deliver to the Trustee and to the holders of the Series K Bonds so to be redeemed a certificate of an officer of the Company stating the amount of the Make- Whole Amount being paid upon such redemption and demonstrating the calculation thereof. The term "PREMIUM" when used in the bonds of Series K or the Indenture in conjunction with references to principal and interest on the bonds of Series K, shall mean any amount due upon any payment, redemption or prepayment of any of the bonds of Series K, other than principal and interest, and shall include the Make-Whole Amount. C. For purposes of this Eighteenth Supplemental Indenture, the term "MAKE-WHOLE AMOUNT" shall mean: to the extent that the Treasury Rate (hereinafter defined) at the time of such redemption is lower than 7.11% per annum, the excess of (i) the present value of the principal and interest payments on and in respect of the Series K Bonds being redeemed, that would otherwise become due and payable (without giving effect to such redemption), discounted semi-annually at a rate which is equal to the Treasury Rate plus 50 basis points over (ii) the principal amount of the Series K Bonds being redeemed. To the extent that the Treasury Rate at the time of such redemption is equal to or higher than PAGE 14 7.11% per annum, the Make-Whole Amount is zero. For purposes of this Eighteenth Supplemental Indenture, the term "TREASURY RATE" shall mean at the time of any redemption with respect toany Series K Bonds being redeemed, the arithmetic average of the two most recent yields to maturity on the United States Treasury obligation with a constant maturity (as compiled by and published by the United States Federal Reserve Statistical Release designated H.15(519) or its successor publication for the two business days next preceding the date of such redemption) most nearly equal to (by rounding to the nearest month) the Remaining Life to Maturity (hereinafter defined) of the Series K Bonds then being redeemed. If no maturity exactly corresponding to such Remaining Life to Maturity of the Series K Bonds shall appear therein, the yields for the two most closely corresponding published maturities shall be calculated pursuant to the foregoing sentence and the Treasury Rate shall be interpolated from such yields on a straight-line basis (rounding, in the case of relevant periods, to the nearest month). For purposes of this Eighteenth Supplemental Indenture, the term "REMAINING LIFE TO MATURITY" of the Series K Bonds shall mean, at any date, the number of years obtained by dividing the then Remaining Dollar-years (hereinafter defined) of such Series K Bonds by the then outstanding principal amount of such Series K Bonds. For purposes of this definition, the "REMAINING DOLLAR-YEARS" of any such Series K Bonds shall mean, at any date, the product obtained by multiplying (i) the aggregate outstanding principal amount of such Series K Bonds, by (ii) the number of twelve-month periods (calculated to the nearest one- twelfth) which will elapse between such date and December 30, 2033. D. Notwithstanding the provisions of Section 2 of Article IV of the Principal Indenture, the Company will cause the Trustee to give irrevocable notice to each registered owner of the Series K Bonds of any redemption of the Series K Bonds pursuant to the preceding paragraphs A or B not less than 30 days nor more than 45 days before the date upon which the redemption is to be made, specifying (i) the date upon which redemption is to be made (the "PREPAYMENT DATE") and (ii) the principal amount of the holder's Series K Bonds to be redeemed on such date. Notice of redemption having been so given, the redemption price payable with respect to the Series K Bonds to be so redeemed shall become due and payable on the Prepayment Date. SECTION 4. Notwithstanding the foregoing provisions of this Article, of Sections 2, 3 and 6 of Article IV of the Principal Indenture and of any bond of Series K: A. Payment of principal, premium, if any, and interest on any bond of Series K and any redemption price of all or a portion of the principal amount thereof shall be made by the Trustee to the registered owner thereof without presentation or surrender thereof to the Trustee if there shall be on file with the Trustee (and not theretofore rescinded by written notice from such registered owner to the Trustee) an agreement (or a conformed copy thereof) between the Company and such registered owner or the person for whom such registered owner is the nominee or a predecessor in interest of such registered owner or the person for whom the registered owner is the nominee, to the effect that (1) payments will be so made, and (2) such registered owner will not sell, pledge, transfer or otherwise dispose of such bond of Series K without first either (i) surrendering such bond of Series K to the Trustee in exchange for a bond or bonds of Series K aggregating the same principal amount as the principal amount of the bond of Series K so surrendered which shall remain unpaid, or (ii) making notation on such bond of Series K (or on a schedule annexed thereto) of all portions of the principal amount thereof which have been redeemed; it being understood that the Bond Purchase Agreement dated as of December 1, 1993 pursuant to which the bonds of Series K were initially issued constitutes such an agreement on file with the Trustee for purposes of PAGE 15 this paragraph A (until rescinded as provided above). The Trustee shall not be under any duty to determine that such notations have been made nor be liable in any manner with respect thereto or with respect to any failure to make such notations. In case any payment is made as provided in this subparagraph A, the Trustee shall make an appropriate notation of such payment on its records, which records shall, in the absence of manifest error, be controlling and conclusive. B. In case less than all of the outstanding bonds of Series K are to be redeemed pursuant to paragraphs A or B of Section 3 of this Article I, the Trustee shall, at the time of each such partial redemption, prorate among the registered owners of the bonds of Series K in proportion to their then respective holdings the amount of bonds of Series K then to be redeemed and designate for redemption the particular bonds of Series K, or the principal amount so prorated, in such manner as the Trustee in its uncontrolled discretion may deem most practicable, PROVIDED, HOWEVER, to the extent, but only to the extent, that such prorating would involve the redemption of bonds of Series K from any registered owner in any amount which would not be an integral multiple of one-hundred thousand dollars ($100,000), the Trustee may, upon any partial redemption, in its reasonable discretion, increase or decrease the amount of bonds of Series K to be redeemed from any registered owner in such manner as the Trustee, in its reasonable discretion, shall deem appropriate to maintain, insofar as possible, the principal of pro rata redemption in any partial redemption or in any series of successive partial redemptions. The acceptance of bonds of Series K by the registered owners thereof shall be deemed to constitute a consent to the foregoing provisions of this subparagraph B with the same force and effect as if the provisions of this subparagraph B had been set forth in a written agreement duly executed by the registered owners of all the bonds of Series K and an executed counterpart of said agreement had been filed with the Trustee. PAGE 16 ARTICLE II SECTION 1. The Company covenants and agrees that, so long as any Series K Bonds are outstanding, dividends (hereinafter defined) paid by the Company subsequent to December 31, 1992 will not exceed net income and earned surplus available for dividends accumulated subsequent to December 31, 1992 determined in accordance with any system of accounts required by law to be followed by the Company, or in the absence of such requirements, in accordance with generally accepted accounting principles consistently applied and with depreciation computed as set forth under Section 2 of Article III of the Principal Indenture, plus an amount of six million nine-hundred and ninety- four thousand dollars ($6,994,000) from earned surplus not appropriated, representing the amount not restricted at December 31, 1992.

In the case of all such sales, leases, transfers and dispositions, at the time of and immediately after giving effect to such sale, lease, transfer or disposition, no condition or event shall exist which constitutes or, after notice or lapse of time or both, would constitute a default or event of default (as defined in the Principal Indenture) under the Principal Indenture; B.

In the case of any sale, transfer, lease or disposition of property or assets by the Company or a Subsidiary, which together with PAGE 17 all other properties and assets sold, leased, transferred or otherwise disposed of by the Company and its Subsidiaries (except in the ordinary course of business) during the same fiscal year have an aggregate bookvalue of more than 5% of the consolidated assets of the Company and its Subsidiaries as shown by a consolidated balance sheet of the Company and its Subsidiaries as at the end of the preceding fiscal year of the Company prepared in accordance with any system of accounts required by law to be followed by the Company, or in the absence of such requirements, in accordance with generally accepted accounting principles consistently applied, the Company shall at the time of such sale, transfer, lease or disposition be permitted to become liable in respect of at least one dollar ($l.00) additional funded debt under Section 17 of Article V of the Principal Indenture; D.
