ENTERGY TEXAS, INC.

FIRST MORTGAGE BONDS, 5.55% SERIES DUE SEPTEMBER 15, 2054

ENTERGY TEXAS, INC., a corporation duly organized and existing under the laws of the State of Texas (herein referred to as the “Company,” which term includes any successor Person under the Indenture referred to below), for value received, hereby promises to pay to

or registered assigns, the principal amount specified above on the Stated Maturity set forth above and to pay interest on the unpaid principal hereof from and including August 15, 2024 or from and including the most recent interest payment date to which interest has been paid or duly provided for semiannually on March 15 and September 15 of each year, commencing March 15, 2025, and on the Stated Maturity (each, an “Interest Payment Date”), at the rate of 5.55% per annum (the “Interest Rate”) to but excluding the date on which the principal hereof is paid or made available for payment. In the event that any Interest Payment Date is not a Business Day (as defined below), then payment of interest 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 such delay) with the same force and effect as if made on the Interest Payment Date. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Business Day immediately preceding such Interest Payment Date (each a “Regular Record Date”), except that interest payable at Maturity will be payable to the Person to whom principal shall be paid. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) 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 the Indenture referred to herein. The Company shall pay interest on such Defaulted Interest (to the extent that payment thereof is enforceable under the applicable law) at the Interest Rate.

A-1

Payment of the principal of and premium, if any, and interest at Maturity on this Security shall be made upon presentation of this Security at the office or agency of the Company maintained for that purpose in The City of New York, in the State of New York, 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, interest on this Security (other than interest payable at Maturity) may be paid by check mailed to the address of the person entitled thereto, as such address shall appear on the Security Register, and provided, further, that if such person is a securities depositary, such payment may be made by such other means in lieu of check as shall be agreed upon by the Company, the Trustee and such person.

All terms used in this Security not otherwise defined herein which are defined in the Indenture shall have the meanings assigned to them in the Indenture and in the Officer’s Certificate establishing the terms of the Securities of this series (the “Series Officer’s Certificate”). “Business Day” means any day other than a Saturday or a Sunday or a day on which banking institutions in The City of New York are authorized or required by law or executive order to remain closed or a day on which the corporate trust office of the Trustee is closed for business.

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, Deed of Trust and Security Agreement, dated as of October 1, 2008 (herein, together with any amendments or supplements thereto, 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, as trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture, for a statement of the property mortgaged, pledged and held in trust, the nature and extent of the security, the conditions upon which the Lien of the Indenture may be released and to the Indenture, Board Resolutions and Series Officer’s Certificate creating the series designated on the face hereof, for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. The acceptance of this Security shall be deemed to constitute the consent and agreement by the Holder thereof to all of the terms and provisions of the Indenture. This Security is one of the series designated on the face hereof.

Prior to March 15, 2054 (the “Par Call Date”), the Securities of this series will be redeemable at the option of the Company, in whole or in part, on not less than 10 days’ notice prior to the date fixed for redemption (each a “Redemption Date”), at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) (a “Redemption Price”) equal to the greater of:

(1) (a) the sum of the present values of the remaining scheduled payments of principal of the Securities of this series to be redeemed and interest thereon discounted to the Redemption Date (assuming the Securities of this series matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 25 basis points less (b) interest accrued to the Redemption Date, and

(2) 100% of the principal amount of the Securities of this series being redeemed,

plus, in either case, accrued and unpaid interest on the Securities of this series being redeemed to, but not including, the Redemption Date.

On or after the Par Call Date, the Securities of this series will be redeemable at the option of the Company, in whole or in part, on not less than 10 days’ notice prior to the Redemption Date, at any time

A-2

and from time to time, at a Redemption Price equal to 100% of the principal amount of the Securities of this series being redeemed plus accrued and unpaid interest thereon to, but not including, the Redemption Date.

“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:

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, or, if published, no longer contains the yields for nominal Treasury constant maturities, 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 as follows:

A-3

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 of such United States Treasury security (expressed as a percentage of principal amount and rounded to three decimal places) at 11:00 a.m., New York City time.

The Company’s actions and determinations in determining the Redemption Price shall be conclusive and binding for all purposes, absent manifest error.

Notice of redemption (other than at the option of the Holder) shall be given by mail to Holders of Securities all as provided in the Indenture. As provided in the Indenture, notice of redemption at the election of the Company as aforesaid may state that such redemption shall be conditional upon the receipt by the applicable Paying Agent or Agents of money sufficient to pay the principal of and premium, if any, and interest, if any, on this Security on or prior to the date fixed for such redemption; a notice of redemption so conditioned shall be of no force or effect if such money is not so received and, in such event, the Company shall not be required to redeem this Security.

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

The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Security upon compliance with certain conditions set forth in the Indenture and the Series Officer’s Certificate.

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 this series at any time by the Company and the Trustee with the consent of the Holders of a majority in aggregate principal amount of the Securities of all series at the time Outstanding to be directly affected thereby. 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.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or the Securities or for the appointment of a receiver or trustee or for any other remedy under or with respect to the Indenture or the Securities, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of a majority in aggregate

A-4

principal amount of the Securities of all series at the time Outstanding in respect of which an Event of Default shall have occurred and be continuing shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as the Trustee and offered the Trustee reasonable indemnity, and the Trustee shall not have received from the Holders of a majority in aggregate principal amount of Securities of all series at the time Outstanding in respect of which an Event of Default shall have occurred and be continuing a direction inconsistent with such request, and shall have failed to institute any such proceeding for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein. 

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 times, place and rate, and in the coin or currency, herein prescribed.

The Securities of this series are issuable only in registered form without coupons in denominations of $1,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein and herein set forth, Securities of this series are exchangeable for Securities of this series, of authorized denominations and of like tenor and aggregate principal amount, 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.

The Company shall not be required to execute, and the Security Registrar shall not be required to register, the transfer of or exchange of (a) Securities of this series during a period of 15 days immediately preceding the date notice is to be given identifying the serial numbers of the Securities of this series called for redemption, (b) any Security during the 15 days before an Interest Payment Date, or (c) any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part.

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 absolute 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.

This Security shall be governed by and construed in accordance with the laws of the State of New York (including without limitation Section 5-1401 of the New York General Obligations Law or any successor to such statute), except to the extent that the Trust Indenture Act shall be applicable.

As provided in the Indenture, no recourse shall be had for the payment of the principal of or premium, if any, or interest on any Securities, or any part thereof, or for any claim based thereon or otherwise in respect thereof, or of the indebtedness represented thereby, or upon any obligation, covenant or agreement under the Indenture, against, and no personal liability whatsoever shall attach to, or be incurred by, any incorporator, shareholder, member, limited partner, officer, manager or director, as such, past, present or future of the Company or of any predecessor or successor of the Company (either directly or through the Company or a predecessor or successor of the Company), whether by virtue of any constitutional provision, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly agreed and understood that the Indenture and all the Securities are solely

A-5

corporate obligations and that any such personal liability is hereby expressly waived and released as a condition of, and as part of the consideration for, the execution of the Indenture and the issuance of the Securities.

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