The Company further covenants and agrees to and with the Trustees and their successors in said trust under the Mortgage, as follows:

SECTION 1.    There shall be a series of bonds designated “4.00% Series due June 1, 2028” (herein sometimes called the “Eighty-seventh Series”), each of which shall also bear the descriptive title “First Mortgage Bond”, and the form thereof, which shall be established by Resolution of the Board of Directors of the Company, shall contain suitable provisions with respect to the matters hereinafter in this Section specified. Bonds of the Eighty-seventh Series (which shall be initially issued in the aggregate principal amount of $250,000,000 shall mature on June 1, 2028, shall be issued as fully registered bonds in the denomination of One thousand Dollars and, at the option of the Company, in any multiple or multiples of One thousand Dollars (the exercise of such option to be evidenced by the execution and delivery thereof), shall bear interest at the rate of 4.00% per annum, the first interest payment to be made on December 1, 2018, for the period from May 11, 2018, to December 1, 2018, with subsequent interest payments payable semi-annually in arrears on June 1 and December 1 of each year (each an “Interest Payment Date”), shall be dated as in Section 10 of the Mortgage provided, and the principal of and interest on each said bond shall be payable at the office or agency of the Company in the Borough of Manhattan, The City of New York, in such coin or currency of the United States of America as at the time of payment is legal tender for public and private debts.

Interest on the bonds of the Eighty-seventh Series will be computed on the basis of a 360-day year of twelve 30-day months. In any case where any Interest Payment Date, redemption date or maturity of any bond of the Eighty-seventh Series shall not be a Business Day, then payment of interest or principal need not be made on such date, but may be made on the next succeeding Business Day, with the same force and effect, and in the same amount, as if made on the corresponding Interest Payment Date or redemption date, or at maturity, as the case may be, and, if such payment is made or duly provided for on such Business Day,

no interest shall accrue on the amount so payable for the period from and after such Interest Payment Date, redemption date or maturity, as the case may be, to such Business Day. “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 Corporate Trustee is closed for business.

So long as all of the bonds of the Eighty-seventh Series are held by The Depository Trust Company or its nominee, or a successor thereof, the record date for the payment of interest on the bonds of the Eighty-seventh Series shall be the Business Day immediately preceding the corresponding Interest Payment Date; provided, however, that the record date for the payment of interest which is paid after such Interest Payment Date, shall be the Business Day immediately preceding the date on which such interest is paid. Interest on the bonds of the Eighty-seventh Series shall be paid to the Person in whose name such bonds of the Eighty-seventh Series are registered at the close of business on the record date for the corresponding Interest Payment Date.

(I) Form of Bonds of the Eighty-seventh Series.

The Bonds of the Eighty-seventh Series, and the Corporate Trustee’s authentication certificate to be executed on the Bonds of the Eighty-seventh Series, shall be in substantially the following forms, respectively:

Unless this Certificate is presented by an authorized representative of The Depository Trust Company, a New York corporation (“DTC”), to the Company or its agent for registration of transfer, exchange, or payment, and any certificate issued is registered in the name of Cede & Co. or in such other name as is requested by an authorized representative of DTC (and any payment is made to Cede & Co. or to such other entity as is requested by an authorized representative of DTC), ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the registered owner hereof, Cede & Co., has an interest herein.

ENTERGY ARKANSAS, INC., a corporation of the State of Arkansas (hereinafter called the Company), for value received, hereby promises to pay to or registered assigns, on June 1, 2028 at the office or agency of the Company in the Borough of Manhattan, The City of New York,

So long as this bond is held by The Depository Trust Company or its nominee, or a successor thereof, the record date for the payment of interest hereon shall be the Business Day (as defined in the Eightieth Supplemental Indenture referred to below) immediately preceding the date on which interest is due; provided, however, that the record date for the payment of interest which is paid after the date on which such interest is due, shall be the Business Day immediately preceding the date on which such interest is paid. Interest hereon shall be paid to the Person in whose name this bond is registered at the close of business on the record date for the payment of such interest. If any interest payment date for this bond falls on a day that is not a Business Day, the payment of interest will be made on the next succeeding Business Day, and no interest on such payment shall accrue for the period from and after such interest payment date. If the maturity date or any redemption date of this bond falls on a day that is not a Business Day, the payment of principal and interest (to the extent payable with respect to the principal being redeemed if on a redemption date) will be made on the next succeeding Business Day, and no interest on such payment shall accrue for the period from and after the maturity date or such redemption date.

The Company and the Trustees may deem and treat the person in whose name this bond is registered as the absolute owner hereof for the purpose of receiving payment and for all other purposes and neither the Company nor the Trustees shall be affected by any notice to the contrary.

The bonds of this series are subject to redemption as provided in the Eightieth Supplemental Indenture.

As used herein, the following defined terms shall have the respective meanings specified unless the context clearly requires otherwise:

The term “Adjusted Treasury Rate” shall mean, 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(519)” or any successor publication which is published 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 bonds of the Eighty-seventh Series being redeemed (assuming, for this purpose, that such bonds of the Eighty-seventh Series mature on March 1, 2028), 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

(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.

The term “Comparable Treasury Issue” shall mean the United States Treasury security selected by the Independent Investment Banker as having a maturity comparable to the remaining term of the bonds of the Eighty-seventh Series being redeemed (assuming, for this purpose, that such bonds of the Eighty-seventh Series mature on March 1, 2028) 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 bonds of the Eighty-seventh Series being redeemed (assuming, for this purpose, that such bonds of the Eighty-seventh Series mature on March 1, 2028).

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