USE OF PROCEEDS

We anticipate that the net proceeds from the issuance and sale of the bonds will be approximately $296.6 million after deducting the underwriting discount and estimated offering expenses payable by us. We intend to use the net proceeds from the issuance and sale of the bonds, together with other available funds, (i) to repay or redeem on or prior to maturity the outstanding $100 million aggregate principal amount of our First Mortgage Bonds, 3.75% Series due July 1, 2024, (ii) to repay debt incurred under our $150 million revolving credit facility which expires in July 2025, (iii) to repay our borrowings under the Entergy system money pool (at May 9, 2024, we had approximately $51 million of outstanding money pool obligations bearing interest at the weighted average rate of approximately 5.21% per year), and/or (iv) for general corporate purposes. Pending the application of the net proceeds from the issuance and sale of the bonds, we may invest them in short-term, highly liquid, high-rated money market instruments and/or the Entergy system money pool. This prospectus supplement shall not constitute a notice of redemption of such first mortgage bonds for which the net proceeds from the issuance and sale of the bonds may be used.

At May 9, 2024, we had $100 million of debt outstanding under our revolving credit facility bearing interest at the weighted average interest rate of approximately 6.55% per year on the drawn portion of the revolving credit facility. Certain of the underwriters, either directly or through affiliates, are lenders under our revolving credit facility and accordingly may receive a portion of the net proceeds from this offering pursuant to the repayment of the borrowings under such revolving credit facility. Certain of the underwriters or their affiliates may own a portion of the first mortgage bonds that may be repaid with the net proceeds from this offering and may, therefore, receive a portion of the net proceeds from this offering. See “Underwriting (Conflicts of Interest) – Conflicts of Interest.”

DESCRIPTION OF THE BONDS

General

The mortgage (as defined in the accompanying prospectus) permits us to issue an unlimited amount of first mortgage bonds from time to time in one or more series, subject to the issuance restrictions set forth in the mortgage, which are generally described in the accompanying prospectus under the heading “Description of the New Bonds – Issuance of Additional First Mortgage Bonds.” All first mortgage bonds of any one series need not be issued at the same time, and a series may be reopened for issuances of additional first mortgage bonds of such series. Thus, we may, from time to time, without notice to or the consent of the existing holders of the bonds, create and issue further first mortgage bonds having the same terms and conditions as the bonds offered hereby in all respects, except for the issue date, the price to public and, if applicable, the initial interest payment date for such first mortgage bonds. Additional first mortgage bonds issued in this manner will be consolidated with, and will form a single series with, the previously outstanding first mortgage bonds of such series. As of March 31, 2024, we had $2.245 billion aggregate principal amount of first mortgage bonds outstanding.

Interest, Maturity and Payment

We are offering $300 million of our First Mortgage Bonds, 5.85% Series due June 1, 2054. We will pay interest on the bonds semi-annually in arrears on June 1 and December 1 of each year, beginning on December 1, 2024. Interest will accrue at the rate of 5.85% per year and will start to accrue from the date that the bonds are issued. As long as the bonds are registered in the name of The Depository Trust Company (“DTC”) or its nominee, the record date for interest payable on any interest payment date shall be the close of business on the Business Day (as defined below) immediately preceding such interest payment date. We have agreed to pay interest on any overdue principal and, if such payment is enforceable under applicable law, on any overdue installment of interest on the bonds at a rate of 6.85% per year to holders of record at the close of business on the Business Day immediately preceding our payment of such interest.

Interest on the bonds will be computed on the basis of a 360-day year consisting of twelve 30-day months. If any interest payment date, redemption date or the maturity date falls on a day that is not a Business Day, the payment due on that interest payment date, redemption date or the maturity date will be made on the next Business Day, and without any interest or other payment in respect of such delay.

S-2

As long as the bonds are registered in the name of DTC or its nominee, we will pay principal, any premium and interest due on the bonds to DTC. DTC will then make payment to its participants for disbursement to the beneficial owners of the bonds as described in the accompanying prospectus under the heading “Description of the New Bonds — Book-Entry Only Securities.”

“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 (as defined in the accompanying prospectus) is closed for business.

Form and Denomination

The bonds will be issued in denominations of $1,000 and integral multiples of $1,000 in excess thereof. The bonds will be represented by a global certificate without coupons registered in the name of a nominee of DTC.

Optional Redemption

Prior to December 1, 2053 (six months prior to the maturity date of the bonds) (the “Par Call Date”), we may redeem the bonds at our option, in whole or in part, on not less than 10 days’ notice prior to the date fixed for redemption, 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) equal to the greater of:

plus, in either case, accrued and unpaid interest thereon to, but not including, the redemption date.

On or after the Par Call Date, we may redeem the bonds, in whole or in part, on not less than 10 days’ notice prior to the date fixed for redemption, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the bonds being redeemed plus accrued and unpaid interest thereon to, but not including, the redemption date.

If, at the time notice of redemption is given, the redemption monies are not held by the trustee, the redemption may be made subject to receipt of such monies before the date fixed for redemption, and such notice shall be of no effect unless such monies are so received.

We may apply cash we deposit under any provision of the mortgage, with certain exceptions, to the redemption or purchase, including the purchase from us, of first mortgage bonds of any series under the mortgage, including the bonds.

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

The Treasury Rate shall be determined by us 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, we shall select, as applicable:

S-3

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, we 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:

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.

Our actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

Purchase of the Bonds

We or our affiliates may, at any time and from time to time, purchase all or some of the bonds at any price or prices by means other than redemption, whether by tender, in the open market, by private negotiated agreement or otherwise, subject to applicable law.

Issuance of Additional First Mortgage Bonds

See “Description of the New Bonds — Issuance of Additional First Mortgage Bonds” in the accompanying prospectus for a description of the bases upon which we are permitted to issue first mortgage bonds under the mortgage and the related requirements for such issuance. As of March 31, 2024, we could have issued approximately $1.214 billion principal amount of first mortgage bonds on the basis of retired first mortgage bonds, and we had approximately $932.8 million of unfunded property additions, entitling us to issue approximately

S-4

$653 million principal amount of first mortgage bonds on the basis of property additions. Such amounts will be affected by the issuance of the bonds, as well as by the use of proceeds to retire certain other outstanding first mortgage bonds, if applicable. The bonds will be issued on the basis of property additions.

Remedies

Effective as of May 1, 2023, the mortgage has been amended to implement the revision described in the second paragraph under “Description of the New Bonds — Remedies — Limitation on Holders’ Right to Institute Proceedings” in the accompanying prospectus.

Additional Information

For additional information about the bonds, see “Description of the New Bonds” in the accompanying prospectus, including:

S-5

UNDERWRITING (CONFLICTS OF INTEREST)

General

Under the terms and conditions set forth in the underwriting agreement, dated the date of this prospectus supplement, we have agreed to sell to each of the underwriters named below, and each of the underwriters has severally and not jointly agreed to purchase, the principal amount of bonds set forth opposite its name below:

Under the terms and conditions set forth in the underwriting agreement, the underwriters have committed, subject to the terms and conditions set forth therein, to take and pay for all of the bonds if any are taken; provided, that under certain circumstances involving a default of an underwriter, less than all of the bonds may be purchased. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

The underwriters initially propose to offer all or part of the bonds directly to the public at the price to public set forth on the cover page hereof and may offer the bonds to certain securities dealers at such price less a concession not in excess of 0.500% of the principal amount of the bonds. The underwriters may allow, and such dealers may reallow to certain brokers and dealers, a concession not in excess of 0.250% of the principal amount of the bonds. After the initial offering of the bonds, the offering price and other selling terms may from time to time be varied by the underwriters. The following table shows the underwriting discount we will pay to the underwriters in respect of this offering:

We estimate that the total expenses payable by us for this offering will be approximately $666,280 excluding the underwriting discount.

We have agreed to indemnify the several underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute to payments that the underwriters may be required to make in that respect.

The bonds will constitute a new class of securities with no established trading market. We cannot assure you as to (1) the liquidity of any such market that may develop, (2) the ability of holders of bonds to sell their bonds or (3) the price at which the holders of bonds would be able to sell their bonds. If such a market develops, the bonds could trade at prices that may be higher or lower than their principal amount or purchase price, depending on many factors, including prevailing interest rates, the market for similar debt securities and our business, results of operations, financial condition or prospects. We do not intend to apply for listing of the bonds on any securities exchange or for inclusion of the bonds in any automated quotation system.

To facilitate the offering of the bonds, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the bonds. Specifically, they may over-allot in connection with the offering, creating a short position in the bonds for their own accounts. In addition, to cover over-allotments or to stabilize

S-6

the price of the bonds, the underwriters may bid for, and purchase, the bonds in the open market. Finally, the underwriters may reclaim selling concessions allowed to dealers for distributing the bonds in the offering, if they repurchase previously distributed bonds in transactions to cover short positions established by them, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the bonds above independent market levels. The underwriters are not required to engage in these activities and may end any of these activities at any time.

Settlement

It is expected that delivery of the bonds will be made on or about the date specified on the cover page of this prospectus supplement, which will be the third business day following the date of this prospectus supplement (such settlement being referred to as “T+3”). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in two business days (T+2), unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the bonds more than two business days prior to the scheduled settlement date will be required, by virtue of the fact that the bonds will initially settle in T+3, to specify an alternative settlement arrangement at the time of any such trade to prevent a failed settlement. Purchasers of the bonds who wish to trade the bonds more than two business days prior to the scheduled settlement date should consult their own advisors.

Certain Relationships

In the ordinary course of their respective businesses, the underwriters and certain of their respective affiliates have in the past and may in the future engage in investment banking, commercial banking or other transactions of a financial nature with us and our affiliates, for which they have received, or may receive, customary compensation. Certain of the underwriters, either directly or through affiliates, are lenders under certain Entergy system credit facilities. In addition, BNY Mellon Capital Markets, LLC, one of the underwriters, is an affiliate of the trustee.

In addition, in the ordinary course of their business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours and/or our affiliates.

If any of the underwriters or their respective affiliates has a lending relationship with us, certain of those underwriters or their affiliates routinely hedge, and may continue to hedge, and certain other of those underwriters or their respective affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, those underwriters and their respective affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the bonds. Any such credit default swaps or short positions could adversely affect future trading prices of the bonds. The underwriters and their respective affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

Conflicts of Interest

We may use a portion of the net proceeds from this offering to repay a portion of the outstanding amounts owed by us under our $150 million revolving credit facility, including amounts we owe to the underwriters or their affiliates who have extended us loans under the credit facility. In addition, certain of the underwriters or their affiliates may own a portion of the first mortgage bonds that may be redeemed or repaid with the net proceeds from this offering. See “Use of Proceeds” in this prospectus supplement. Because more than 5% of the net proceeds from this offering may be used to repay amounts owed to one or more underwriters (or their affiliates) in respect of such credit facility or in respect of such first mortgage bonds, this offering is being made in compliance with the requirements of Rule 5121 of the Financial Industry Regulatory Authority, Inc. (“Rule 5121”). Under Rule 5121, the appointment of a “qualified independent underwriter” is not necessary in

S-7

connection with this offering, as this offering is of a class of securities that are “investment grade rated” within the meaning of Rule 5121. In order to comply with Rule 5121, any underwriter that has a conflict of interest within the meaning of Rule 5121 may not make sales in this offering to any accounts over which it exercises discretionary authority without first receiving the specific written approval of the account holder and maintaining such approval in that underwriter’s records.

EXPERTS

The financial statements and the related financial statement schedule of Entergy Mississippi, LLC as of December 31, 2023 and 2022, and for each of the three years in the period ended December 31, 2023, incorporated by reference in this Prospectus Supplement, have been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their reports. Such financial statements and financial statement schedule are incorporated by reference in reliance upon the reports of such firm given their authority as experts in accounting and auditing.

Morgan, Lewis & Bockius LLP may rely on the opinion of Wise Carter Child & Caraway, Professional Association as to matters of Mississippi law relevant to its opinion, and on the opinion of Husch Blackwell LLP as to matters of Texas law relevant to its opinion. Wise Carter Child & Caraway, Professional Association may rely on the opinion of Morgan, Lewis & Bockius LLP as to matters of New York law relevant to its opinion, and on the opinion of Husch Blackwell LLP as to matters of Texas law relevant to its opinion. Husch Blackwell LLP may rely on the opinion of Wise Carter Child & Caraway, Professional Association as to matters of Mississippi law relevant to its opinion, and on the opinion of Morgan, Lewis & Bockius LLP as to matters of New York law relevant to its opinion.

DESCRIPTION OF THE NEW BONDS

The following description sets forth the general terms and provisions of the New Bonds that we may offer by this prospectus. We will describe in one or more prospectus supplements the particular terms of the New Bonds and provisions that vary from those described below.

We will issue the New Bonds offered by this prospectus from time to time in one or more series under one or more separate supplemental indentures to the Mortgage and Deed of Trust dated as of February 1, 1988, with The Bank of New York Mellon, successor trustee (the “trustee”). This Mortgage and Deed of Trust, as it has heretofore been and may be amended or supplemented from time to time, is referred to in this prospectus as the “mortgage.” All first mortgage bonds issued or to be issued under the mortgage, including the New Bonds offered by this prospectus, are referred to herein as “first mortgage bonds.”

This section of the prospectus contains a summary of certain terms and provisions of the mortgage. The mortgage contains the full legal text of the matters described in this section. Because this section is a summary, it does not describe every aspect of the New Bonds or the mortgage. The mortgage is filed as an exhibit to the registration statement of which this prospectus forms a part. You should read the mortgage for provisions that may be important to you. This summary is subject to and qualified in its entirety by reference to all the provisions of the mortgage, including the definitions of some of the terms used in the mortgage. This summary is also subject to and qualified by reference to the description of the particular terms of each series of New Bonds described in the applicable prospectus supplement or supplements. The mortgage has been qualified under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”), and you should also refer to the Trust Indenture Act for provisions that apply to the New Bonds.

General

The mortgage permits us to issue first mortgage bonds from time to time in an unlimited aggregate amount subject to the limitations described under “—Issuance of Additional First Mortgage Bonds.” All first mortgage bonds of any one series need not be issued at the same time, and a series may be reopened for issuances of additional first mortgage bonds of that series. This means that we may from time to time, without notice to or consent of the existing holders of the first mortgage bonds of any series, including the New Bonds, create and issue additional first mortgage bonds of a series having the same terms and conditions as the previously issued first mortgage bonds of that series in all respects, except for issue date, price to public and, if applicable, the initial interest payment on those additional first mortgage bonds. Additional first mortgage bonds issued in this manner will be consolidated with, and will form a single series with, the previously issued first mortgage bonds of that series. For more information, see the discussion below under “—Issuance of Additional First Mortgage Bonds.”

Terms of Specific Series of the New Bonds

The prospectus supplement relating to each series of New Bonds offered by this prospectus will include a description of the specific terms relating to the offering of that series. These terms will include any of the following terms that apply to that series:

3

As of June 30, 2022, we had approximately $2,195 million principal amount of first mortgage bonds outstanding under the mortgage.

We may sell New Bonds at a discount below their principal amount or at a premium above their principal amount. United States federal income tax considerations applicable to New Bonds sold at an original issue discount will be described in the applicable prospectus supplement if we sell New Bonds at an original issue discount. In addition, important United States federal income tax or other tax considerations applicable to any New Bonds denominated or payable in a currency or currency unit other than United States dollars will be described in the applicable prospectus supplement if we sell New Bonds denominated or payable in a currency or currency unit other than United States dollars.

Except as may otherwise be described in the applicable prospectus supplement, the covenants contained in the mortgage will not afford holders of New Bonds protection in the event of a highly-leveraged or a change of control transaction involving us.

Payment

The New Bonds and interest thereon will be paid in any coin or currency of the United States of America that at the time of payment is legal tender at the corporate trust office of the trustee in the Borough of Manhattan, City and State of New York. See “—Book-Entry Only Securities” for additional information relating to payment on the New Bonds.

Redemption and Retirement

We will set forth any terms for the redemption of New Bonds of any series in the applicable prospectus supplement. Unless we indicate differently in a prospectus supplement, and except with respect to New Bonds redeemable at the option of the holder of those New Bonds, the New Bonds will be redeemable upon notice to holders by mail at least 30 days prior to the redemption date. Unless the New Bonds are held in book-entry only form through the facilities of The Depository Trust Company (“DTC”), in which case DTC’s procedures for selection shall apply (see “—Book-Entry Only Securities”), if less than all of the New Bonds of any series are to be redeemed, the trustee will select the New Bonds to be redeemed.

Unless we default in the payment of the redemption price and accrued interest, if any, in the case of an unconditional notice of redemption, the New Bonds subject to such notice of redemption will cease to bear interest on the redemption date. We will pay the redemption price and any accrued interest to the redemption date upon presentation and surrender of any New Bond for redemption. If only part of a New Bond is redeemed, the trustee will deliver to the holder of the New Bond a new New Bond of the same series for the remaining portion without charge.

We may make any redemption at our option conditional upon the receipt by the trustee, prior to the date fixed for redemption, of money sufficient to pay the redemption price and accrued interest, if any. If the trustee has not received the money by the date fixed for redemption, we will not be required to redeem the New Bonds.

Form and Exchange

The New Bonds will be fully-registered first mortgage bonds without coupons. See “—Book-Entry Only Securities.” The New Bonds will be exchangeable for other New Bonds of the same series in equal aggregate

4

principal amounts. No service charge will be made for any registration of transfer or exchange of the New Bonds. However, we may require payment to cover any tax or other governmental charge that may be imposed in connection with a registration, transfer or exchange. We will not be required to provide for the transfer or exchange of any New Bond:

Security

The New Bonds, together with all other first mortgage bonds outstanding now or in the future under the mortgage, will be secured by the mortgage. The mortgage constitutes a first mortgage lien on substantially all of our property (the “mortgaged property”) subject to bankruptcy law and:

The mortgage does not create a lien on the following “excepted property”:

The mortgage contains provisions that impose the lien of the mortgage on property we acquire after the date of the mortgage, other than excepted property, subject to pre-existing liens. However, if we consolidate or merge with, or convey or transfer all or substantially all of our mortgaged property to, another entity, the lien created by the mortgage will generally not cover the property of the successor company, other than the mortgaged property it acquires from us and improvements, replacements and additions to such property.

The mortgage also provides that the trustee has a lien on the mortgaged property to ensure the payment of its reasonable compensation, expenses and disbursements and for indemnity against certain liabilities. This lien takes priority over the lien securing the first mortgage bonds, including the New Bonds.

We have reserved the right to amend the mortgage without the consent or other action by the holders of any first mortgage bonds created after April 30, 2016, including the New Bonds, to revise the definition of “excepted encumbrances” to mean the following:

5

Issuance of Additional First Mortgage Bonds

Subject to the issuance restrictions described below, the aggregate principal amount of first mortgage bonds that we can issue under the mortgage is unlimited. First mortgage bonds of any series may be issued from time to time on the basis of:

Property additions generally include, among other things, electric, gas, steam or hot water property acquired after December 31, 1987. Securities, automobiles, vehicles or aircraft, or property used principally for the production or gathering of natural gas, are not included as property additions. Deposited cash may be withdrawn upon the bases stated in clause (1) or (2) above.

As of June 30, 2022, we could have issued approximately $964 million principal amount of first mortgage bonds on the basis of retired first mortgage bonds, and we had approximately $819 million of unfunded property additions, entitling us to issue approximately $573 million principal amount of first mortgage bonds on the basis of property additions. Such amounts will be affected by the issuance of any additional first mortgage bonds, including the New Bonds, and the retirement of existing first mortgage bonds with the proceeds of the New Bonds. New Bonds in a greater amount may also be issued for the refunding of outstanding first mortgage bonds.

The mortgage contains restrictions on the issuance of first mortgage bonds against property subject to liens.

There is no “earnings” or similar test required under the mortgage as a condition to the issuance of first mortgage bonds under the mortgage.

6

Other than the security afforded by the lien of the mortgage and restrictions on the issuance of additional first mortgage bonds described above, there are no provisions of the mortgage that grant the holders of the first mortgage bonds protection in the event of a highly-leveraged transaction involving us.

Release and Substitution of Property

Property may be released from the lien of the mortgage on the following bases:

Property owned by us on December 31, 1987, may be released from the lien of the mortgage at its depreciated book value on December 31, 1987; all other property may be released at its cost, as defined in the mortgage. Unfunded property may also be released without complying with clauses (1), (2) or (3) above if, after its release, we would have at least one dollar of unfunded property that remains subject to the lien of the mortgage.

We can withdraw cash upon the bases stated in clauses (2) and/or (3) above.

Generally, “Funded Property” under the mortgage means all mortgaged property owned by us on December 31, 1987, and all property additions used as the basis for the issuance of first mortgage bonds, the release of mortgaged property or the withdrawal of cash held by the trustee. We may at any time, without further consent of any holders of first mortgage bonds, change the definition of “Funded Property” to mean any mortgaged property specified by us with a fair value, to be determined by an independent expert, of not less than 10/7ths of the sum of the amount of the outstanding first mortgage bonds and retired bond credits, together with all property additions thereafter used as the basis for the issuance of first mortgage bonds, the release of mortgaged property or the withdrawal of cash held by the trustee.

We may, without any release or consent by the trustee, cancel or make changes or alterations in or substitutions for any and all easements, servitudes, rights-of-way and similar rights and/or interests.

Modification

Modification Without Consent

Without the consent of any holder of first mortgage bonds, we and the trustee may enter into one or more supplemental indentures for any of the following purposes:

7

Modification Requiring Consent

Except as provided below, the consent of the holders of a majority in aggregate principal amount of then outstanding first mortgage bonds, considered as one class, is required for all other amendments or modifications to the mortgage. However, if less than all of the series of first mortgage bonds outstanding are directly affected by a proposed amendment or modification, then the consent of the holders of only a majority in aggregate principal amount of the outstanding first mortgage bonds of all series that are directly affected, considered as one class, will be required. Notwithstanding the foregoing, no amendment or modification may be made without the consent of the holder of each directly affected first mortgage bond then outstanding to:

The mortgage provides that first mortgage bonds owned by us, for our benefit or by any affiliate of ours shall not be deemed outstanding for the purpose of certain votes, consents or quorums; provided that first mortgage bonds that have been pledged in good faith may be regarded as outstanding if the pledgee establishes to the satisfaction of the trustee its right to vote such first mortgage bonds and such pledgee is not our affiliate.

Any request, consent or vote of the owner of any first mortgage bond will bind every future holder and owner of that first mortgage bond and the holder and owner of every first mortgage bond issued upon the registration of transfer of or in exchange for that first mortgage bond.

Defaults and Notices Thereof

Defaults under the mortgage include:

8

The trustee may withhold notice of default, except in payment of principal, interest or funds for purchase or redemption of first mortgage bonds, if the trustee in good faith determines it is in the interests of the holders of first mortgage bonds.

Remedies

Acceleration of Maturity

If a default under the mortgage occurs and is continuing, then the trustee, by written notice to us, or the holders of at least 25% in aggregate principal amount of the outstanding first mortgage bonds, by written notice to us and the trustee, may declare the principal amount of all of the first mortgage bonds to be due and payable immediately, and upon the giving of such notice, such principal amount and accrued and unpaid interest will become immediately due and payable.

There is no automatic acceleration, even in the event of our bankruptcy, insolvency or reorganization.

Annulment of Acceleration

At any time after such a declaration of acceleration has been made but before any sale of the mortgaged property, the holders of a majority in principal amount of all outstanding first mortgage bonds may annul such declaration of acceleration, by written notice to us and the trustee, if the default under the mortgage giving rise to such declaration of acceleration has been cured, and we have paid or deposited with the trustee a sum sufficient to pay:

Trustee Powers

Subject to the mortgage, under specified circumstances and to the extent permitted by law, if a default under the mortgage occurs, the trustee shall be entitled to the appointment of a receiver for the mortgaged property and is entitled to all other remedies available under applicable law.

Control by Holders

The holders of a majority in principal amount of the first mortgage bonds then outstanding may direct the time, method and place of conducting any proceedings for any remedy available to the trustee or exercising any trust or power conferred on the trustee. The trustee is not obligated to comply with directions that conflict with law or other provisions of the mortgage or that the trustee determines in good faith would involve the trustee in personal liability, would be unjustifiably prejudicial to non-assenting holders or would be in circumstances where

9

indemnity would not be sufficient. The trustee is not required to risk its funds or incur personal liability if there is reasonable ground for believing that repayment is not reasonably assured.

Limitation on Holders’ Right to Institute Proceedings

No holder of first mortgage bonds will have any right to institute any proceeding under the mortgage, or any remedy under the mortgage, unless:

provided that no holder or holders of first mortgage bonds shall have any right in any manner to affect or prejudice the lien of the mortgage or to obtain priority over other holders of outstanding first mortgage bonds. However, these limitations do not apply to the absolute and unconditional right of a holder of a first mortgage bond to institute suit for payment of the principal, premium, if any, or interest on the first mortgage bond on or after the applicable due date.

We have the right to amend the mortgage at any time without any consent or other action of the holders of any of the New Bonds to revise the limitations described in the first sentence of the immediately preceding paragraph to apply to any proceeding or remedy under or with respect to the mortgage or the first mortgage bonds.

Evidence to be Furnished to the Trustee

Compliance with the mortgage provisions is evidenced by written statements of our officers or persons we select or pay. In certain cases, opinions of counsel and certifications of an engineer, accountant, appraiser or other expert (who in some cases must be independent) must be furnished. We must give the trustee an annual certificate as to whether or not we have fulfilled our obligations under the mortgage throughout the preceding year.

Satisfaction and Discharge of Mortgage

After we provide for the payment of all of the first mortgage bonds (including the New Bonds) and after paying all other sums due under the mortgage, the mortgage may be satisfied and discharged. The first mortgage bonds will be deemed to have been paid when money or Eligible Obligations (as defined below) sufficient to pay the first mortgage bonds (in the opinion of an independent accountant in the case of Eligible Obligations) at maturity or upon redemption have been irrevocably set apart or deposited with the trustee; provided that the trustee shall have received an opinion of counsel to the effect that the setting apart or deposit does not require registration under the Investment Company Act of 1940, as amended, does not violate any applicable laws and does not result in a taxable event with respect to the holders of the first mortgage bonds prior to the time of their right to receive payment. “Eligible Obligations” means obligations of the United States of America that do not permit the redemption thereof at the issuer’s option.

Consolidation, Merger and Conveyance of Assets

The mortgage provides that we may consolidate with or merge into any other entity or convey, transfer or lease as, or substantially as, an entirety to any entity the mortgaged property, if:

10

In the case of the conveyance or other transfer of the mortgaged property as, or substantially as, an entirety to another entity, upon the satisfaction of all the conditions described above, the successor entity would be substituted for us under the mortgage, but we would not be released and discharged from our obligations on the first mortgage bonds then outstanding.

If we transfer as an entirety all or substantially all of our mortgaged property to a successor, the successor will assume all of our obligations under the mortgage and we may be released from all such obligations.

The mortgage does not prevent or restrict any conveyance or other transfer or lease of any part of the mortgaged property that does not constitute the entirety, or substantially the entirety, of the mortgaged property.

Although the successor entity may, in its sole discretion, subject to the lien of the mortgage property then owned or thereafter acquired by the successor entity, the lien of the mortgage generally will not cover the property of the successor entity other than the mortgaged property it acquires from us and improvements, extensions and additions to such property and renewals, replacements and substitutions thereof, within the meaning of the mortgage.

The terms of the mortgage do not restrict mergers in which we are the surviving entity.

The mortgage provides:

11

Release of Obligations under New Bonds upon Transfer of All or Substantially All Mortgaged Property

If we transfer as an entirety all or substantially all of our mortgaged property to a successor, the successor will assume all of our obligations under the New Bonds and we may be released of all such obligations.

Consent to Amendments

Each initial and future holder of the New Bonds, by its acquisition of an interest in such New Bonds, will irrevocably (a) consent to the amendments to the mortgage described herein, without any other or further action by any holder of such New Bonds, and (b) designate the trustee, and its successors, as its proxy with irrevocable instructions to vote and deliver written consents on behalf of such holder in favor of such amendments at any meeting of bondholders, in lieu of any meeting of bondholders, in response to any consent solicitation or otherwise.

Information about the Trustee

The trustee is The Bank of New York Mellon. In addition to acting as trustee, The Bank of New York Mellon also acts, and may act, as trustee under various other of our and our affiliates’ indentures, trusts and guarantees. We and our affiliates maintain deposit accounts and credit and liquidity facilities and conduct other banking transactions with the trustee and its affiliates in the ordinary course of our respective businesses.

So long as no default or event that, after notice or lapse of time, or both, would become a default has occurred and is continuing and except with respect to a trustee appointed by act of the holders, if we have delivered to the trustee a board resolution appointing a successor trustee and the successor has accepted the appointment in accordance with the terms of the mortgage, the trustee will be deemed to have resigned and the successor will be deemed to have been appointed as trustee in accordance with the mortgage.

Book-Entry Only Securities

Unless otherwise specified in the applicable prospectus supplement, the New Bonds will trade through DTC. Each series of New Bonds will be represented by one or more global certificates and registered in the name of Cede & Co., DTC’s nominee. Upon issuance of the global certificates, DTC or its nominee will credit, on its book-entry registration and transfer system, the principal amount of the New Bonds represented by such global certificates to the accounts of institutions that have an account with DTC or its participants. The accounts to be credited shall be designated by the agents, brokers, dealers or underwriters involved in the issuance. Ownership of beneficial interests in the global certificates will be limited to participants or persons that may hold interests through participants. The global certificates will be deposited with the trustee as custodian for DTC.

DTC is a limited-purpose trust company organized under the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to Section 17A of the Exchange Act. DTC holds and provides asset servicing for over 3.5 million issues of U.S. and non-U.S. equity issues, corporate and municipal debt issues, and money market instruments (from over 100 countries) that DTC’s participants deposit with DTC. DTC also facilitates the post-trade settlement among participants of sales and other securities transactions in deposited securities, through electronic computerized book-entry transfers and pledges in the participants’ accounts. This eliminates the need for physical movement of securities certificates. Participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, and clearing corporations that clear through or maintain a custodial relationship with a participant. DTC rules applicable to its participants are on file with the SEC. More information about DTC can be found at www.dtcc.com.

12

Purchases of the New Bonds within the DTC system must be made by or through participants, who will receive a credit for the New Bonds on DTC’s records. The ownership interest of each actual purchaser of each New Bond (“Beneficial Owner”) is in turn to be recorded on the participants’ records. Beneficial Owners will not receive written confirmation from DTC of their purchase. Beneficial Owners are, however, expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the participants through whom they purchased New Bonds. Transfers of ownership interests in the New Bonds are to be accomplished by entries made on the books of the participants acting on behalf of Beneficial Owners. Beneficial Owners will not receive certificates for their New Bonds of a series, except in the event that use of the book-entry system for the New Bonds of that series is discontinued.

To facilitate subsequent transfers, all New Bonds deposited by participants with DTC are registered in the name of DTC’s nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of the New Bonds with DTC and their registration in the name of Cede & Co. or such other DTC nominee do not effect any change in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the New Bonds. DTC’s records reflect only the identity of the participants to whose accounts such New Bonds are credited, which may or may not be the Beneficial Owners. The participants will remain responsible for keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by DTC to participants, and by participants to Beneficial Owners, will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time. Beneficial Owners of the New Bonds may wish to take certain steps to augment the transmission to them of notices of significant events with respect to the New Bonds, such as redemptions, tenders, defaults, and proposed amendments to the mortgage. Beneficial Owners of the New Bonds may wish to ascertain that the nominee holding the New Bonds has agreed to obtain and transmit notices to the Beneficial Owners. In the alternative, Beneficial Owners may wish to provide their names and addresses to the registrar and request that copies of notices be provided directly to them.

Redemption notices will be sent to DTC. If less than all of the New Bonds of a series are being redeemed, DTC’s practice is to determine by lot the amount of New Bonds of such series held by each participant to be redeemed.

Neither DTC nor Cede & Co. (nor any other DTC nominee) will itself consent or vote with respect to New Bonds, unless authorized by a participant in accordance with DTC’s procedures. Under its usual procedures, DTC would mail an omnibus proxy to us as soon as possible after the record date. The omnibus proxy assigns the consenting or voting rights of Cede & Co. to those participants to whose accounts the New Bonds are credited on the record date (identified in a listing attached to the omnibus proxy).

Payments of redemption proceeds, principal of, and interest on the New Bonds will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit participants’ accounts upon DTC’s receipt of funds and corresponding detail information from us or the trustee, on the payable date in accordance with their respective holdings shown on DTC’s records. Payments by participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in “street-name,” and will be the responsibility of participants and not of DTC, the trustee, or us, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of redemption proceeds, principal and interest to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) is the responsibility of the trustee or us, disbursement of such payments to participants is the responsibility of DTC, and disbursement of such payments to the Beneficial Owners is the responsibility of participants.

Except as provided in the applicable prospectus supplement, a Beneficial Owner will not be entitled to receive physical delivery of the New Bonds. Accordingly, each Beneficial Owner must rely on the procedures of DTC to exercise any rights under the New Bonds.

13

DTC may discontinue providing its services as securities depositary with respect to the New Bonds at any time by giving reasonable notice to us or the trustee. In the event no successor securities depositary is obtained, certificates for the New Bonds will be printed and delivered. We may decide to replace DTC or any successor depositary. Additionally, subject to the procedures of DTC, we may decide to discontinue use of the system of book-entry transfers through DTC (or a successor depositary) with respect to some or all of the New Bonds. In that event, certificates for the New Bonds of such series will be printed and delivered. If certificates for such series of New Bonds are printed and delivered,

The information in this section concerning DTC and DTC’s book-entry system has been obtained from sources that we believe to be reliable, but we do not take any responsibility for the accuracy of this information.

PLAN OF DISTRIBUTION

Methods and Terms of Sale

We may use a variety of methods to sell the New Bonds including:

The prospectus supplement relating to a particular series of the New Bonds will set forth the terms of the offering of the New Bonds, including:

Underwriters

If we sell the New Bonds through underwriters, they will acquire the New Bonds for their own account and may resell them from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The underwriters for a particular underwritten offering of New Bonds will be named in the applicable prospectus supplement and, if an underwriting syndicate is used, the managing underwriter or underwriters will be named on the cover page of the applicable prospectus supplement. In connection with the sale of New Bonds, the underwriters may receive compensation from us or from purchasers in the form of discounts, concessions or commissions. The obligations of the underwriters to purchase New Bonds will be subject to certain conditions. The underwriters will be obligated to purchase all of the New Bonds of a particular series if any are purchased. However, the underwriters may purchase less than all of the New Bonds of a particular series should certain circumstances involving a default of one or more underwriters occur.

14

The initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers by any underwriters may be changed from time to time.

Stabilizing Transactions

Underwriters may engage in stabilizing transactions and syndicate-covering transactions in accordance with Rule 104 of Regulation M under the Exchange Act. Stabilizing transactions permit bids to purchase the underlying New Bonds so long as the stabilizing bids do not exceed a specified maximum. Syndicate-covering transactions involve purchases of the New Bonds in the open market after the distribution has been completed in order to cover syndicate short positions. These stabilizing transactions and syndicate-covering transactions may cause the price of the New Bonds to be higher than it would otherwise be if such transactions had not occurred.

Agents

If we sell the New Bonds through agents, the applicable prospectus supplement will set forth the name of any agent involved in the offer or sale of the New Bonds as well as any commissions we will pay to them. Unless otherwise indicated in the applicable prospectus supplement, any agent will be acting on a best-efforts basis for the period of its appointment.

Related Transactions

Underwriters, dealers and agents (or their affiliates) may engage in transactions with, or perform services for, us or our affiliates in the ordinary course of business.

Indemnification

We will agree to indemnify any underwriters, dealers, agents or purchasers and their controlling persons against certain civil liabilities, including liabilities under the Securities Act.

Listing

Unless otherwise specified in the applicable prospectus supplement, the New Bonds will not be listed on a national securities exchange. No assurance can be given that any broker-dealer will make a market in any series of the New Bonds, and, in any event, no assurance can be given as to the liquidity of the trading market for any of the New Bonds.
