(a) the sum of the present values of the remaining scheduled payments of principal and interest on the Series DD Notes to be redeemed discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined herein) plus 15 basis points less (b) interest accrued to the date of redemption, and

•

100% of the principal amount of the Series DD Notes to be redeemed,

plus, in either case, accrued and unpaid interest thereon to, but excluding, the redemption date.

Section 402. Redemption of Series EE Notes

Prior to the Series EE Notes Par Call Date (defined below), the Company may redeem the Series EE Notes at its option, in whole or in part, at any time and from time to time, on not less than 10 nor more than 60 days’ prior written notice mailed (or delivered by electronic transmission in accordance with the applicable procedures of DTC) to the holders of the Series EE Notes, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

•

(a) the sum of the present values of the remaining scheduled payments of principal and interest on the Series EE Notes to be redeemed discounted to the redemption date (assuming the Series EE Notes matured on the Series EE Notes Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined herein) plus 25 basis points less (b) interest accrued to the date of redemption, and

•

100% of the principal amount of the Series EE Notes to be redeemed,

plus, in either case, accrued and unpaid interest thereon to, but excluding, the redemption date.

On or after the Series EE Notes Par Call Date (defined below), the Company may redeem the Series EE Notes, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the Series EE Notes being redeemed plus accrued and unpaid interest thereon to, but excluding, the redemption date.

Section 403. Definitions Applicable to Redemption Provisions.

As used in this Article Four:

“Series EE Notes Par Call Date” means, October 1, 2033 (the date that is three months prior to the maturity date of the Series EE Notes).

“Treasury Rate” means, with respect to any redemption date, the yield determined by the Company in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) - H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities - Treasury constant maturities - Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to, in the case of the Series DD Notes, the maturity date of the Series DD Notes, or, in the case of the Series EE Notes, the Series EE Notes Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields - one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life - and shall interpolate to, in the case of the Series DD Notes, the maturity date of the Series DD Notes, or, in the case of the Series EE Notes, the Series EE Notes Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third business day preceding the redemption date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to in the case of the Series DD Notes, the maturity date of the Series DD Notes, or, in the case of the Series EE Notes, the Series EE Notes Par Call Date, as applicable. If there is no United States Treasury security maturing on in the case of the Series DD Notes, the maturity date of the Series DD Notes, or, in the case of the Series EE Notes, the Series EE Notes Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the maturity date of the Series DD Notes or the Series EE Notes Par Call Date, as applicable, one with a maturity date preceding the maturity date of the Series DD Notes or the Series EE Notes Par Call Date, as applicable, and one with a maturity date following the maturity date of the Series DD Notes or the Series EE Notes Par Call Date, as applicable, the Company shall select the United States Treasury security with a maturity date preceding in the case of the Series DD Notes, the maturity date of the Series DD Notes, or, in the case of the Series EE Notes, the Series EE Notes Par Call Date. If there are two or more United States Treasury securities maturing on in the case of the Series DD Notes, the maturity date of the Series DD Notes, or, in the case of the Series EE Notes, the Series EE Notes Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

Our actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error. The Trustee shall have no responsibility to calculate the redemption price.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the redemption date to each holder of Series DD Notes or Series EE Notes, as applicable, to be redeemed.

In the case of a partial redemption, selection of the Series DD Notes or the Series EE Notes, as applicable, for redemption will be made by lot or pursuant to the applicable depositary’s procedures. No notes of a principal amount of $2,000 or less will be redeemed in part. If any Series DD Note or Series EE Note is to be redeemed in part only, the notice of redemption that relates to such Series DD Note or Series EE Note will state the portion of the principal amount of the Series DD Note or Series EE Note, as applicable, to be redeemed. A new Series DD Note or Series EE Note, as applicable, in a principal amount equal to the unredeemed portion of the Series DD Note or Series EE Note, as applicable, will be issued in the name of the holder of the Series DD Note or Series EE Note, as applicable, upon surrender for cancellation of the original Series DD Note or Series EE Note, as applicable. For so long as the Series DD Notes or Series EE Notes, as applicable, are held by DTC (or another depositary), the redemption of the Series DD Notes or Series EE Notes, as applicable, shall be done in accordance with the policies and procedures of the depositary.

On and after the redemption date interest will cease to accrue on the Series DD Notes or Series EE Notes, as applicable, or portions thereof called for redemption. Prior to any redemption date, the Company is required to deposit with a paying agent money sufficient to pay the redemption price of and accrued interest on the Series DD Notes or the Series EE Notes, as applicable, to be redeemed on such date.

Any redemption may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, the completion or occurrence of a related transaction or event, as the case may be, and any notice of redemption made in connection with a related transaction or event may, at the Company’s discretion, be given prior to the completion or the occurrence thereof. If such redemption is subject to satisfaction of one or more conditions precedent, such notice will describe each such condition, and if applicable, will state that, at the Company’s discretion, the redemption date may be delayed until such time (including more than 60 days after the date the notice of redemption was mailed or delivered, including by electronic transmission) as any or all such conditions are satisfied (or waived by the Company in its sole discretion), or that such redemption may not occur and such notice may be rescinded in the event that any or all such conditions are not satisfied (or waived by the Company in its sole discretion) by the redemption date, or by the redemption date as so delayed, or that such notice may be rescinded at any time in the Company’s discretion if in its good faith judgment any or all of such conditions will not be satisfied. If any such condition precedent has not been satisfied, the Company shall provide written notice prior to the close of business on the business day immediately prior to the redemption date. Upon receipt of such notice, the notice of redemption shall be rescinded or delayed, and the redemption of the Series DD Notes or the Series EE Notes, as applicable, shall be rescinded or delayed as provided in such notice.

“The Trustee shall have the right to accept and act upon instructions, including funds transfer instructions (“Instructions”) given pursuant to this Indenture and delivered using Electronic Means; provided, however, that the Company shall provide to the Trustee an incumbency certificate listing officers with the authority to provide such Instructions (“Authorized Officers”) and containing specimen signatures of such Authorized Officers, which incumbency certificate shall be amended by the Company whenever a person is to be added or deleted from the listing. If the Company elects to give the Trustee Instructions using Electronic Means and the Trustee in its discretion elects to act upon such Instructions, the Trustee’s understanding of such Instructions shall be deemed controlling. The Company understands and agrees that the Trustee cannot determine the identity of the actual sender of such Instructions and that the Trustee shall conclusively presume that directions that purport to have been sent by an Authorized Officer listed on the incumbency certificate provided to the Trustee have been sent by such Authorized Officer. The Company shall be responsible for ensuring that only Authorized Officers transmit such Instructions to the Trustee and that the Company and all Authorized Officers are solely responsible to safeguard the use and confidentiality of applicable user and authorization codes, passwords and/or authentication keys upon receipt by the Company. The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee’s reliance upon and compliance with such Instructions notwithstanding such directions conflict or are inconsistent with a subsequent written instruction. The Company agrees: (i) to assume all risks arising out of the use of Electronic Means to submit Instructions to the Trustee, including without limitation the risk of the Trustee acting on unauthorized Instructions, and the risk of interception and misuse by third parties; (ii) that it is fully informed of the protections and risks associated with the various methods of transmitting Instructions to the Trustee and that there may be more secure methods of transmitting Instructions than the method(s) selected by the Company; (iii) that the security procedures (if any) to be followed in connection with its transmission of Instructions provide to it a commercially reasonable degree of protection in light of its particular needs and circumstances; and (iv) to notify the Trustee immediately upon learning of any compromise or unauthorized use of the security procedures.”

Section 503. Section 401 of the Original Indenture.

Section 401 of the Original Indenture shall not apply to the Series DD Notes or the Series EE Notes. Section 401 of the Original Indenture is hereby amended in its entirety with respect to the Series DD Notes and Series EE Notes to state:

provided, however, that if the Trustee or any Paying Agent is required to return any money deposited with it as described in this Section 401 to the Company or its representative under any applicable Federal or state bankruptcy, insolvency or similar law, this Indenture shall retroactively be deemed not to have been satisfied and discharged and automatically shall be reinstated and shall remain in full force and effect without any further action, but the Company shall execute and deliver such instruments as the Trustee shall reasonably request to evidence and acknowledge the same.

Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 607 hereof, the obligations of the Trustee to any Authenticating Agent under Section 614 hereof and, if money shall have been deposited with the Paying Agent or the Trustee pursuant to subclause (B) of clause (1) of this Section 401, the obligations of the Company and the Trustee under Sections 401, 402, 1002 and 1003 hereof shall survive.”

EVERSOURCE ENERGY, a voluntary association duly organized and existing under the laws of the Commonwealth of Massachusetts (the “Company”, which term includes any successor entity under the Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co., or registered assigns, the principal sum of ________________________ ($__________) on January 1, 2027 (the “Final Maturity”), and to pay interest thereon from January 19, 2024 or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually in arrears on January 1 and July 1 of each year, commencing on July 1, 2024, at the rate of 5.00% per annum, until the principal hereof is paid or made available for payment and, subject to the terms of the Indenture, at the same rate 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, the 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 New York, New York or in Pittsburgh, Pennsylvania on which banking institutions are authorized or required by law, regulation or executive order to close.

A-1

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 (1) the Business Day next preceding such Interest Payment Date if this Security remains in book-entry only form or (2) the 15th calendar day (whether or not a Business Day) next preceding such Interest Payment Date if this Security does not remain in book-entry only form. 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 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 premium, if any) and any interest on this Security will be made at the office or agency of the Company maintained for that purpose at the Corporate Trust Office of the Trustee 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.

This Security has initially been issued in the form of a Global Security, and the Company has initially designated The Depository Trust Company, New York, New York (the “Depositary,” which term shall include any successor depositary), as the Depositary for this Security. For as long as this Security or any portion hereof is issued in such form, and notwithstanding the previous paragraph, all payments of interest, principal and other amounts in respect of this Security or portion thereof shall be made to the Depositary or its nominee in accordance with its applicable policies and procedures, in the coin or currency specified above and as further provided on the reverse hereof.

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 or electronic 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 Global Security]

EVERSOURCE ENERGY

SENIOR NOTES, SERIES DD, DUE 2027

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 April 1, 2002, as amended and supplemented from time to time and as supplemented by the Twenty-First Supplemental Indenture dated as of January 1, 2024 (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, initially limited in aggregate principal amount to $__________. 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 ten (10) or more than sixty (60) days’ notice by mail to the Holders of such securities at their addresses in 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, it will do so at a Redemption Price set forth in Section 401 of the Twenty-First Supplemental Indenture between the Company and the Trustee, dated January 1, 2024, which established the terms of the Securities.

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.

A-3

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.

This Security shall be exchangeable for Securities registered in the names of Persons other than the Depositary with respect to such series or its nominee only as provided in this paragraph. This Security shall be so exchangeable if (x) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for such series or at any time ceases to be a clearing agency registered as such under the Securities Exchange Act of 1934, (y) the Company executes and delivers to the Trustee an Officers’ Certificate providing that this Security shall be so exchangeable or (z) there shall have occurred and be continuing an Event of Default with respect to the Securities of the series of which this Security is a part. Securities so issued in exchange for this Security shall be of the same series, having the same interest rate, if any, and maturity and having the same terms as this Security, in authorized denominations and in the aggregate having the same principal amount as this Security and registered in such names as the Depositary for such Global Security shall direct.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of a Security of the series of which this Security is a part is registrable in the Security Register, upon surrender of this Security for 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 the series of which this Security is a part are issuable only in registered form without coupons in minimum denominations of $2,000 and integral multiples of $1,000 thereafter. 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.

A-4

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.

For so long as this Security is issued in the form of a Global Security, neither the Company nor the Trustee will have any responsibility with respect to the policies and procedures of the Depositary or for any notices or other communications among the Depositary, its direct and indirect participants or the beneficial owners of this Security.

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 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.

The Declaration of Trust of the Company provides that no shareholder of the Company shall be held to any liability whatsoever for the payment of any sum of money, or for damages or otherwise under any contract, obligation or undertaking made, entered into or issued by the trustees of the Company or by any officer, agent or representative elected or appointed by the trustees and no such contract, obligation or undertaking shall be enforceable against the trustees or any of them in their or his individual capacities or capacity and all such contracts, obligations and undertakings shall be enforceable only against the trustees as such, and every person, firm, association, trust and corporation having any claim or demand arising out of any such contract, obligation or undertaking shall look only to the trust estate for the payment or satisfaction thereof.

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.
