SECTION 208.

Optional Redemption.

At any time or from time to time prior to August 15, 2023 (three months prior to the maturity date of the Notes), the Company may, at its option, in accordance with Article Eleven of the Original Indenture (as amended by this Seventh Supplemental Indenture) upon notice as provided below, redeem any part of the Notes, in an amount not less than 5% of the aggregate principal amount of the Notes then outstanding in the case of a partial prepayment, at the Redemption Price equal to 100% of the principal amount so prepaid, and the Make-Whole Amount determined for the Redemption Date with respect to such principal amount, plus accrued and unpaid interest, if any, to the Redemption Date. Notice will be given in the manner provided in Section 1104 of the Original Indenture to each Holder of the Notes, with a copy to the Trustee, of each optional redemption under this Section 208 not less than 30 days and not more than 60 days prior to the date fixed for such redemption. Each such notice shall contain the information specified in Section 1104 of the Original Indenture and shall also specify the aggregate principal amount of the Notes to be redeemed on the Redemption Date, the principal amount of each Note held by such Holder to be redeemed and the interest to be paid on the Redemption Date with respect to such principal amount being redeemed, and shall be accompanied by a certificate of a Senior Financial Officer as to the estimated Make-Whole Amount due in connection with such redemption (calculated as if the date of such notice were the date of the redemption), setting forth the details of the computation. Two Business Days prior to such redemption, the Issuer shall deliver to each Holder of Notes, with a copy to the Trustee, a certificate of a Senior Financial Officer specifying the calculation of such Make-Whole Amount as of the Redemption Date.

In the case of each partial redemption of the Notes pursuant to this Section 208, the principal amount of the Notes to be redeemed shall be allocated among all of the Notes at the time outstanding in proportion, as nearly as practicable, to the respective unpaid principal amount thereof not theretofore called for redemption.

The Company acknowledges, and the parties hereto agree, that each Holder of a Note has the right to maintain its investment in the Notes free from repayment by the Company (except as herein specifically provided for) and that the provision for payment of a Make-Whole Amount by the Company in the event that the Notes are redeemed, in accordance with this Section 208 or are accelerated as a result of an Event of Default, is intended to provide compensation for the deprivation of such right under such circumstances.

The Notes may be redeemed on or after August 15, 2023 (three months prior to the maturity date of the Notes), in accordance with Article Eleven of the Original Indenture being (as amended by this Seventh Supplemental Indenture), at a redemption price (to be calculated by the Company) equal to one hundred percent (100%) of the principal amount of the Notes being redeemed, plus accrued and unpaid interest thereon to, but excluding, the Redemption Date.

For the purposes of this Section 208:

“Make-Whole Amount” means, with respect to any Note, an amount equal to the excess, if any, of the Discounted Value of the Remaining Scheduled Payments with respect to the Called Principal of such Note over the amount of such Called Principal, provided that the Make-Whole Amount may in no event be less than zero. For the purposes of determining the Make-Whole Amount, the following terms have the following meanings:

“Called Principal” means, with respect to any Note, the principal of such Note that is to be prepaid pursuant to Section 208 of this Seventh Supplemental Indenture or has become or is declared to be immediately due and payable pursuant to Section 502 of the Original Indenture.

“Discounted Value” means, with respect to the Called Principal of any Note, the amount obtained by discounting all Remaining Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Redemption Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the same periodic basis as that on which interest on the Notes is payable) equal to the Reinvestment Yield with respect to such Called Principal.

“Redemption Date” with respect to the Called Principal has the meaning set forth in the Original Indenture.

“Reinvestment Yield” means, with respect to the Called Principal of any Note, .50% over the yield to maturity implied by the yield(s) reported as of 10:00 a.m. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as “Page PX1” (or such other display as may replace Page PX1) on Bloomberg Financial Markets for the most recently issued actively traded on-the-run U.S. Treasury securities (“Reported”) having a maturity equal to the Remaining Average Life of

such Called Principal as of such Redemption Date. If there are no such U.S. Treasury securities Reported having a maturity equal to such Remaining Average Life, then such implied yield to maturity will be determined by (a) converting U.S. Treasury xxxx quotations to bond equivalent yields in accordance with accepted financial practice and (b) interpolating linearly between the yields Reported for the applicable most recently issued actively traded on-the-run U.S. Treasury securities with the maturities (1) closest to and greater than such Remaining Average Life and (2) closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Note.

If such yields are not Reported or the yields Reported as of such time are not ascertainable (including by way of interpolation), then “Reinvestment Yield” means, with respect to the Called Principal of any Note, .50% over the yield to maturity implied by the U.S. Treasury constant maturity yields reported, for the latest day for which such yields have been so reported as of the second Business Day preceding the Redemption Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (or any comparable successor publication) for the U.S. Treasury constant maturity having a term equal to the Remaining Average Life of such Called Principal as of such Redemption Date. If there is no such U.S. Treasury constant maturity having a term equal to such Remaining Average Life, such implied yield to maturity will be determined by interpolating linearly between (1) the U.S. Treasury constant maturity so reported with the term closest to and greater than such Remaining Average Life and (2) the U.S. Treasury constant maturity so reported with the term closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Note. The Reinvestment Yield shall be determined by the Company in the manner set forth herein.

“Remaining Average Life” means, with respect to any Called Principal, the number of years obtained by dividing (i) such Called Principal into (ii) the sum of the products obtained by multiplying (a) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (b) the number of years, computed on the basis of a 360-day year composed of twelve 30-day months and calculated to two decimal places, that will elapse between the Redemption Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment.

“Remaining Scheduled Payments” means, with respect to the Called Principal of any Note, all payments of such Called Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its scheduled due date, provided that if such Redemption Date is not a date on which interest payments are due to be made under the Notes, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Redemption Date and required to be paid on such Redemption Date.

SECTION 209.

Redemption of Notes Upon Change of Control.

(a)

Condition to Company Action. Within five (5) Business Days of a Senior Financial Officer of the Company becoming aware of a Change of Control, the Company shall give to each Holder of Notes, with a copy to the Trustee, written notice containing a description, in reasonable detail, of the Change of Control (the “Company Notice”). The Company Notice

shall contain and constitute an offer to redeem the Notes as described in subparagraph (b) of this Section 2.09, and shall also contain the information described in subparagraph (e) of this Section 2.09.

(b)

Offer to Redeem Notes. The offer to redeem the Notes contemplated by subparagraph (a) of this Section 2.09 shall be an offer to redeem, in accordance with and subject to this Section 2.09, all, but not less than all, the Notes held by each such Holder (in this case only, “Holder” in respect of any Note registered in the name of a nominee for a disclosed beneficial owner shall mean such beneficial owner) on the date specified in such offer (the “Proposed Redemption Date”) that is a Business Day and is not less than 30 days and not more than 60 days after the date of such offer.

(c)

Acceptance, Rejection. A Holder of Notes may accept the offer to redeem the Notes made pursuant to this Section 2.09 by causing a notice of such acceptance to be delivered to the Company and the Trustee at least 5 days prior to the Proposed Redemption Date. A failure by a Holder of Notes to respond to an offer of redemption made pursuant to this Section 2.09 shall be deemed to constitute a rejection of such offer by such Holder.

(d)

Redemption. Redemption of the Notes to be redeemed pursuant to this Section 2.09 shall be 100% of the principal amount of such Notes, together with interest in such Notes accrued to the Redemption Date. The redemption shall be made on the Proposed Redemption Date and the Redemption Price shall be deposited with the Trustee by 11:00 a.m. one Business Day prior to the Redemption Date. For avoidance of doubt no Make-Whole Amount shall be paid in connection with any redemption of the Notes pursuant to this Section 2.09.

(e)

Company’s Certificate. Each offer to redeem the Notes pursuant to this Section 2.09 shall be by notice given in the manner provided in Section 1104 of the Original Indenture and shall be accompanied by a certificate, executed by a Senior Financial Officer of the Company and dated as of the date of such offer, specifying: (i) the Proposed Redemption Date; (ii) that such offer is made pursuant to this Section 2.09; (iii) the principal amount of each Note offered to be redeemed (which shall be 100% of the principal amount of such Note); (iv) the interest that would be due on each Note offered to be redeemed, accrued to the Proposed Redemption Date; (v) that the condition of this Section 2.09 have been fulfilled; and (vi) in reasonable detail, the nature and date of the Change of Control.

(a)

Compliance with Law. Without limiting Section 1015(c), the Company will, and will cause each of its Subsidiaries to, comply with all laws, ordinances or governmental rules or regulations to which each of them is subject, including, without limitation, ERISA, Environmental Laws, the USA PATRIOT Act and the other laws and regulations that are referred to in Section 5.16 of the Note Purchase Agreements, and will obtain and maintain in effect all licenses, certificates, permits, franchises and other governmental authorizations necessary to the ownership of their respective properties or to the conduct of their respective businesses, in each case to the extent necessary to ensure that non-compliance with such laws,

ordinances or governmental rules or regulations or failures to obtain or maintain in effect such licenses, certificates, permits, franchises and other governmental authorizations would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

(b)

Payment of Taxes. The Company will, and will cause each of its Subsidiaries to, file all income tax or similar tax returns required to be filed in any jurisdiction and to pay and discharge all taxes shown to be due and payable on such returns and all other taxes, assessments, governmental charges, or levies payable by any of them, to the extent the same have become due and payable and before they have become delinquent, provided that neither the Company nor any Subsidiary need pay any such tax, assessment, charge or levy if (i) the amount, applicability or validity thereof is contested by the Company or such Subsidiary on a timely basis in good faith and in appropriate proceedings, and the Company or a Subsidiary has established adequate reserves therefor in accordance with GAAP on the books of the Company or such Subsidiary or (ii) the nonpayment of all such taxes, assessments, charges and levies would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

(c)

Books and Records. The Company will, and will cause each of its Subsidiaries to, maintain proper books of record and account in conformity with GAAP and all applicable requirements of any Governmental Authority having legal or regulatory jurisdiction over the Company or such Subsidiary, as the case may be. The Company will, and will cause each of its Subsidiaries to, keep books, records and accounts which, in reasonable detail, accurately reflect all transactions and dispositions of assets. The Company and its Subsidiaries have devised a system of internal accounting controls sufficient to provide reasonable assurances that their respective books, records, and accounts accurately reflect all transactions and dispositions of assets and the Company will, and will cause each of its Subsidiaries to, continue to maintain such system.

(b)

Line of Business. The Company will not and will not permit any Subsidiary to engage in any business if, as a result, the general nature of the business in which the Company and its Subsidiaries, taken as a whole, would then be engaged would be substantially changed from the general nature of the business in which the Company and its Subsidiaries, taken as a whole, are engaged on the date of this Agreement as described in the Memorandum.

(c)

Terrorism Sanctions Regulations. The Company will not and will not permit any Controlled Entity (a) to become (including by virtue of being owned or controlled by a Blocked Person), own or control a Blocked Person or any Person that is the target of sanctions

imposed by the United Nations or by the European Union, or (b) directly or indirectly to have any investment in or engage in any dealing or transaction (including, without limitation, any investment, dealing or transaction involving the proceeds of the Notes) with any Person if such investment, dealing or transaction (i) would cause any holder to be in violation of any law or regulation applicable to such holder, or (ii) is prohibited by or subject to sanctions under any U.S. Economic Sanctions, or (c) to engage, nor shall any Affiliate of either engage, in any activity that could subject such Person or any holder to sanctions under CISADA or any similar law or regulation with respect to Iran or any other country that is subject to U.S. Economic Sanctions.

(d)

Consolidated Indebtedness to Capitalization Ratio. The Company will not permit its Consolidated Indebtedness to Capitalization Ratio to be greater than 0.65:1.00 as of the end of any fiscal quarter.”

ARTICLE SIX

Redemption of Securities.

WESTERN MASSACHUSETTS ELECTRIC COMPANY, a corporation duly organized and existing under the laws of the Commonwealth of Massachusetts (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 thereon from the date of original 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, until the principal hereof is paid or made available for payment, and at the Applicable Rate set forth above on any overdue principal and premium and (to the extent that the payment of such interest shall be legally enforceable) on any overdue installment of interest.

The amount of interest payable for any period other than a complete interest payment period will be computed on the basis of a 360-day year consisting of twelve thirty day months and, for any period shorter than a full month, on the basis of the actual number of days elapsed in such period. In any case where any Interest Payment Date, Stated Maturity or Redemption Date is not a Business Day, then payment of principal and interest, if any, or principal and premium, if any, payable on such date will be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of any such delay), in each case with the same force and effect as if made on such date. A “Business Day” shall mean any day, except a Saturday, a Sunday or a legal holiday in The City of New York or in Pittsburgh, Pennsylvania on which banking institutions are authorized or required by law, regulation or executive order to close.

The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture, be paid to the Person in whose name this Security is registered at the close of business on the Regular Record Date for such interest, which shall be the 15th calendar day (whether or not a Business Day) next preceding such Interest Payment Date. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such date and may either be paid to the Person in whose name this Security is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of

A-1

Securities of this series not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture.

Payment of the principal of (and any Make-Whole Amount) and any interest on this Security will be made at the office or agency of the Company maintained for that purpose in Pittsburgh, Pennsylvania, 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; provided, however, that at the option of the Company payment of interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register.

Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof by manual signature, this Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

[Form of Reverse of Security]

WESTERN MASSACHUSETTS ELECTRIC COMPANY

SENIOR NOTES, SERIES G, DUE 2023

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of September 1, 2003 as amended and supplemented from time to time and as supplemented by the Seventh Supplemental Indenture dated as of November 1, 2013 (herein called the “Indenture,” which term shall have the meaning assigned to it in such instrument), between the Company and The Bank of New York Mellon Trust Company, N.A., formerly known as The Bank of New York Trust Company, N.A. (as successor trustee to The Bank of New York), as Trustee (herein called the “Trustee,” which term includes any successor trustee under Indenture), as to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof, limited initially in aggregate principal amount to $80,000,000. The provisions of this Security, together with the provisions of the Indenture, shall govern the rights, obligations, duties and immunities of the Holder, the Company and the Trustee with respect to this Security, provided that, if any provision of this Security conflicts with any provision of the Indenture, the provision of this Security shall be controlling to the fullest extent permitted under the Indenture.

The Securities of this series are subject to redemption upon not less than thirty (30) or more than sixty (60) days’notice by mail to the Holders of such securities at their addresses in

A-2

the Security Register, at the option of the Company, in whole or in part, from time to time. If the Company elects to redeem the Securities prior to August 15, 2023, it will do so at a Redemption Price equal to one hundred percent (100%) of the principal amount of the Securities being redeemed, plus accrued and unpaid interest thereon to but excluding the Redemption Date, plus the Make-Whole Amount. If the Company elects to redeem the Securities on or after August 15, 2023, it will do so at a Redemption Price equal to one hundred percent (100%) of the principal amount of the Securities being redeemed, plus accrued and unpaid interest thereon to but excluding the Redemption Date.

Except as otherwise provided in the Indenture, if notice has been given as provided in the Indenture and funds for the redemption of any Securities (or any portion thereof) called for redemption shall have been made available on the Redemption Date referred to in such notice, such Securities (or any portion thereof) will cease to bear interest on the date fixed for such redemption specified in such notice and the only right of the Holders of such Securities will be to receive payment of the Redemption Price.

In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

The Securities of this series will not be subject to any sinking fund.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

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 Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of all series to be affected (voting as one class). The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the time, place and rate, and in the coin or currency, herein prescribed.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer this Security is registrable in the Security Register, upon surrender of this Security for

A-3

registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The Securities of this series are issuable only in registered form without coupons 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. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

Neither the failure to give any notice nor any defect in any notice given to the Holder of this Security or any other Security of this series will affect the sufficiency of any notice given to any other Holder of any Securities of this series.

The Indenture provides that the Company, at its option (a) will be discharged from any and all obligations in respect of the Securities (except for certain obligations to register the transfer or exchange of Securities, replace stolen, lost or mutilated Securities, maintain paying agencies and hold moneys for payment in trust) or (b) need not comply with certain restrictive covenants of the Indenture, in each case if the Company deposits, in trust, with the Trustee money or U.S. Government Obligations which, through the payment of interest thereon and principal thereof in accordance with their terms, will provide money, in an amount sufficient to pay all the principal of, and premium, if any, and interest, if any, on the Securities on the dates such payments are due in accordance with the terms of such Securities, and certain other conditions are satisfied.

No recourse shall be had for the payment of the principal of or the interest on this Security, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture or any indenture supplemental thereto, against any trustee, incorporator, stockholder, officer or director, as such, past, present or future, of the Company or any successor corporation, either directly or through the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or

A-4

penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issuance hereof, expressly waived and released.

This Security shall be governed by and construed in accordance with the laws of the State of New York.

All terms used in this Security not defined herein which are defined in the Indenture shall have the meanings assigned to them in the Indenture.
