FIRST MORTGAGE BONDS, 1.50% SERIES DUE SEPTEMBER 1, 2026

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 Maturity Date set forth above and to pay interest on the unpaid principal hereof from and including August 17, 2021 or from and including the most recent interest payment date to which interest has been paid or duly provided for semiannually on March 1 and September 1 of each year, commencing March 1, 2022, and on the Maturity Date (each, an “Interest Payment Date”), at the rate of 1.50% 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.

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

A-1

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”).

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.

Securities of this series shall be redeemable at the option of the Company in whole or in part, upon notice mailed at least 30 days but not more than 60 days prior to the date fixed for redemption (the “Redemption Date”) (i) at any time prior to August 1, 2026 (the “Par Call Date”), at a price (the “Redemption Price”) equal to the greater of (a) 100% of the principal amount of Securities of this series being redeemed and (b) as determined by the Independent Investment Banker, the sum of (x) the present value of the payment on the Par Call Date of the principal amount of the Securities of this series being redeemed plus (y) the sum of the present values of the remaining scheduled payments of interest on the Securities of this series being redeemed to the Par Call Date (excluding the portion of any such interest accrued to the Redemption Date), discounted (for purposes of determining such present values) to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate plus 15 basis points, and (ii) at any time on or after the Par Call Date, at the Redemption Price equal to 100% of the principal amount of Securities of this series being redeemed, plus, in each case, any accrued and unpaid interest thereon to, but not including, the Redemption Date.

“Adjusted Treasury Rate” means, with respect to any redemption date:

(1) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15” or any successor publication which is published at least weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the remaining term of the Securities of this series (assuming, for this purpose, that the Securities of this series mature on the Par Call Date), yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Adjusted Treasury Rate shall be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month); or

A-2

(2) if such release (or any successor release) is not published during the week preceding the calculation date for the Adjusted Treasury Rate or does not contain such yields, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date.

The Adjusted Treasury Rate shall be calculated on the third Business Day preceding the redemption date.

“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.

“Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker as having a maturity comparable to the remaining term of the Securities of this series (assuming, for this purpose, that the Securities of this series mature on the Par Call Date) that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Securities of this series (assuming, for this purpose, that the Securities of this series mature on the Par Call Date).

“Comparable Treasury Price” means, with respect to any redemption date, (1) the average of five Reference Treasury Dealer Quotations for such redemption date after excluding the highest and lowest such Reference Treasury Dealer Quotations or (2) if the Independent Investment Banker obtains fewer than five such Reference Treasury Dealer Quotations, the average of all such Reference Treasury Dealer Quotations.

“Independent Investment Banker” means one of the Reference Treasury Dealers that we appoint to act as the Independent Investment Banker from time to time or, if any of such firms is unwilling or unable to select the Comparable Treasury Issue, an independent investment banking institution of national standing appointed by the Company.

“Reference Treasury Dealer” means (1) Scotia Capital (USA) Inc. and a Primary Treasury Dealer (as defined below) selected by SMBC Nikko Securities America, Inc., or in each case, an affiliate thereof, and their respective successors; provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), the Company will substitute therefor another Primary Treasury Dealer, and (2) any other Primary Treasury Dealer selected by the Independent Investment Banker after consultation with the Company.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Banker at 5:00 p.m. on the third Business Day preceding such redemption date.

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.

A-3

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 thereunder, 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 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.
