(b) The Company will, within 30 days following the date of the occurrence of a Change of Control, or at the Company’s option, prior to the occurrence of any Change of Control, but after the public announcement of the Change of Control, send written notice of such Change of Control to each Holder (determined as of the date of such notice), with a copy to the Trustee. Such notice shall contain and constitute a Change of Control Offer.

(c) The notice contemplated by paragraphs 19(a) and (b) hereof shall state, among other things, the repurchase date, which shall be not less than 30 days nor more than 60 days after the date of such notice, other than as may be required by law (the “Change of Control Payment Date”). The notice, if mailed prior to the date of the occurrence of the Change of Control, shall state that the Change of Control Offer is conditioned on the Change of Control occurring on or prior to the Change of Control Payment Date.

(d) A Holder may accept or reject a Change of Control Offer by causing a notice of such acceptance or rejection to be delivered to the Company at least five Business Days prior to the Change of Control Payment Date. A failure by a Holder to so respond to a Change of Control Offer shall be deemed to constitute a rejection of such offer by such Holder. A Holder electing to have its Bonds repurchased pursuant to a Change of Control Offer will be required to surrender its Bonds, with such customary documents of surrender and transfer as the Company may reasonably request duly completed or transfer its Bonds by book-entry transfer, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day prior to the Change of Control Payment Date.

(e) On the Change of Control Payment Date, the Company will, to the extent lawful:

(i) accept for payment all Bonds properly tendered by the Holders thereof pursuant to the Change of Control Offer;

(ii) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Bonds properly tendered by the Holders thereof; and

(iii) deliver or cause to be delivered to the Trustee the Bonds properly accepted by the Company, together with an Officers’ Certificate stating the aggregate principal amount of Bonds being repurchased.

6

(f) The Paying Agent will promptly transmit to each Holder of properly tendered Bonds (or, if all of the Bonds are then in global form, make such payment through the facilities of DTC) the Change of Control Payment for the Bonds being repurchased, and the Trustee will promptly authenticate a new bond equal in principal amount to any unrepurchased portion of any Bonds surrendered, provided that each new bond will be in a principal amount of $1,000 or an integral multiple of $1,000 in excess thereof.

(g) The Company will not be required to make a Change of Control Offer if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for such an offer made by the Company and such third party purchases all Bonds properly tendered and not withdrawn under its offer. In addition, the Company will not repurchase any Bonds if there has occurred and is continuing on the Change of Control Payment Date an Event of Default under the Mortgage, other than a default in the payment of the Change of Control Payment upon the occurrence of a Change of Control.

(h) If Holders of not less than 90% in aggregate principal amount of the outstanding Bonds validly tender and do not withdraw such Bonds in a Change of Control Offer and the Company, or any third party making such offer in lieu of the Company, repurchases all of the Bonds validly tendered and not withdrawn by such Holders, the Company or such third party will have the right, upon not less than 10 days nor more than 60 days’ prior written notice, provided that such notice is given not more than 60 days following such repurchase pursuant to the Change of Control Offer described above, to redeem all of the Bonds that remain outstanding following such purchase on a date specified in such notice (the “Second Change of Control Payment Date”) and at a price in cash equal to 101% of the aggregate principal amount of Bonds repurchased plus any accrued and unpaid interest on the Bonds repurchased to, but not including, the Second Change of Control Payment Date.

(i) The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of the Bonds pursuant to a Change of Control Offer. To the extent that any securities laws or regulations conflict with the “Change of Control” provisions of the Bonds, the Company shall comply with the applicable securities laws and regulations and shall be deemed not to have breached the Company’s obligations under the “Change of Control” provisions of the Bonds as set forth in this paragraph 19 by virtue thereof.

(j) “Change of Control” means the occurrence of any of the following events: (i) Entergy (as defined below) ceases to own, directly or indirectly, all of the Company’s outstanding Voting Stock (as defined below) (or the Voting Stock of any successor to the Company); or (ii) the direct or indirect sale, transfer, conveyance or other disposition, in one or a series of related transactions, of all or substantially all of the Company’s assets to any “person” or “group” (as those terms are used in Section 13(d)(3) of the Exchange Act) other than to Entergy or one of its subsidiaries.

(k) For purposes of the provisions contained in this paragraph 19, the following terms shall be defined as follows:

“Entergy” means Entergy Corporation, a Delaware corporation (or its successors or assigns).

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 the 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 the 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, 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:

(1) the Company shall select (a) the United States Treasury security maturing on the Par Call Date, subject to clause (3) below, or (b) if there is no United States Treasury security maturing on the Par Call Date, then the United States Treasury security with the maturity date that is closest to the Par Call Date, subject to clauses (2) and (3) below, as applicable; or

(2) if there is no United States Treasury security described in clause (1), but there are two or more United States Treasury securities with maturity dates equally distant from the Par Call Date, one or more with maturity dates preceding the Par Call Date and one or more with maturity dates following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding and closest to the Par Call Date, subject to clause (3) below; or

(3) if there are two or more United States Treasury securities meeting the criteria of the preceding clauses (1) or (2), 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.

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 Mortgage. As provided in the Mortgage, 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.

Upon the occurrence of a Change of Control, each Holder of the Securities of this series will have the right to require that the Company purchase all or a portion of such Holder’s Securities of this series pursuant to paragraph 19 of the Series Officer’s Certificate.

The Mortgage contains provisions for defeasance at any time of the entire indebtedness of this Security upon compliance with certain conditions set forth in the Mortgage 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 Mortgage.

The Mortgage 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 Mortgage 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 Mortgage and certain past defaults under the Mortgage 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 Mortgage, the Holder of this Security shall not have the right to institute any proceeding with respect to the Mortgage 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

A-4

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 Mortgage and no provision of this Security or of the Mortgage 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 Mortgage 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 Mortgage, 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 Mortgage, 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 Mortgage and all the Securities are solely 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 Mortgage and the issuance of the Securities.
