COLLATERAL TRUST MORTGAGE BONDS, 5.15% SERIES DUE SEPTEMBER 15, 2034

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

or registered assigns, the principal amount specified above on the Stated Maturity set forth above and to pay interest on the unpaid principal hereof and on any overdue interest from and including August 9, 2024 or from and including the most recent interest payment date to which interest has been paid or duly provided for semiannually on March 15 and September 15 of each year, commencing March 15, 2025, and on the Stated Maturity (each, an “Interest Payment Date”), at the rate of 5.15% per annum 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.

A-1

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

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

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under a Mortgage and Deed of Trust, dated as of November 1, 2015 (herein, together with any amendments or supplements thereto, including the Twentieth Supplemental Indenture, dated as of August 1, 2024, with respect to the Securities of this series, 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 and Series Officer’s Certificate creating the series designated on the face hereof, for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. The acceptance of this Security shall be deemed to constitute the consent and agreement by the Holder thereof to all of the terms and provisions of the Indenture. This Security is one of the series designated on the face hereof.

Prior to June 15, 2034 (the “Par Call Date”), the Securities of this series will be redeemable at the option of the Company, in whole or in part, on not less than 10 nor more than 60 days’ notice prior to the date fixed for redemption (each, a “Redemption Date”), at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) (a “Redemption Price”) equal to the greater of:

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

On or after the Par Call Date, the Securities of this series will be redeemable at the option of the Company, in whole or in part, on not less than 10 nor more than 60 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 Securities of this series being redeemed plus accrued and unpaid interest thereon to, but not including, the Redemption Date.

A-2

“Treasury Rate” means, with respect to any Redemption Date, the yield determined by the Company in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the Redemption Date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) – H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities – Treasury constant maturities – Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Company shall select, as applicable:

For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

If on the third Business Day preceding the Redemption Date H.15 TCM is no longer published, or, if published, no longer contains the yields for nominal Treasury constant maturities, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such Redemption Date as follows:

A-3

In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices of such United States Treasury security (expressed as a percentage of principal amount and rounded to three decimal places) at 11:00 a.m., New York City time.

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

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

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

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

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of this series at any time by the Company and the Trustee with the consent of the Holders of a majority in aggregate principal amount of the Securities of all series at the time Outstanding to be directly affected thereby. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

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

A-4

satisfactory to it, 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 the Trustee shall have failed to institute any such proceeding for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

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

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

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

The Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the absolute owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

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

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

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

The Company further covenants and agrees to and with the Trustee and its successor or successors in said trust under the Mortgage as follows:

ARTICLE I

ONE HUNDRED FOURTH SERIES BONDS

SECTION 1 There shall be a series of bonds designated “5.15% Series due September 15, 2034” (herein sometimes called the “One Hundred Fourth Series”), each of which shall also bear the descriptive title “First Mortgage Bond,” and the form thereof, which has been established by Resolution of the Board of Directors of the Company, is attached hereto as Exhibit A. Bonds of the One Hundred Fourth Series (which shall be issued initially in the aggregate principal amount of $700,000,000) shall be dated as in Section 10 of the Mortgage provided, shall mature on September 15, 2034, shall be issued as fully registered bonds in any integral multiple or multiples of One Thousand Dollars, and shall bear interest at the rate of 5.15% per annum, the first interest payment to be made on March 15, 2025, for the period from August 9, 2024, to March 15, 2025 with subsequent interest payments payable semiannually on March 15 and September 15 of each year (each, an “Interest Payment Date”), the principal of and interest on each said bond to 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 One Hundred Fourth Series shall be paid to the Person in whose name such bonds of the One Hundred Fourth Series are registered.

13

Interest on the bonds of the One Hundred Fourth 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 the maturity date of any bond of the One Hundred Fourth Series shall not be a Business Day, then payment of interest or principal and premium, if any, 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, 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 the maturity date, 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 Trustee is closed for business.

The bonds of the One Hundred Fourth Series shall be issued by the Company, registered in the name of and delivered to The Bank of New York Mellon, as trustee (together with its successors as trustee under the Collateral Trust Mortgage referenced below, the “Collateral Trust Trustee”) under the Mortgage and Deed of Trust of the Company dated as of November 1, 2015 as the same may be supplemented and amended from time to time (the “Collateral Trust Mortgage”), to provide for the payment when due (whether at maturity, by acceleration or otherwise) of the principal and interest of the Securities (as defined in the Collateral Trust Mortgage) to be issued from time to time under the Collateral Trust Mortgage.

Any payment by the Company under the Collateral Trust Mortgage of the principal of or interest on the Securities which shall have been authenticated and delivered under the Collateral Trust Mortgage on the basis of the issuance and delivery to the Collateral Trust Trustee of bonds of the One Hundred Fourth Series (other than by application of the proceeds of a payment in respect of such bonds) shall, to the extent of such payment, be deemed to satisfy and discharge the obligation of the Company, if any, to make a payment of principal of, or interest on such bonds, as the case may be, which is then due.

The Trustee may conclusively presume that the obligation of the Company to pay the principal of and interest on the bonds of the One Hundred Fourth Series as the same shall become due and payable shall have been fully satisfied and discharged unless and until it shall have received a written notice from the Collateral Trust Trustee signed by its President, a Vice President, an Assistant Vice President or a Trust Officer, stating that interest or principal due and payable on any Securities issued under the Collateral Trust Mortgage has not been fully paid and specifying the amount of funds required to make such payment.

(I) Each holder of a bond of the One Hundred Fourth Series consents that the bonds of the One Hundred Fourth Series may be redeemed at the option of the Company or pursuant to the requirements of the Mortgage in whole at any time, or in part from time to time, prior to maturity, without notice provided in Section 52 of the Mortgage, at the principal amount of the bonds to be redeemed, in each case, together with accrued interest to the date fixed for redemption by the Company in a notice delivered to the Trustee and to the holder of the bonds to be redeemed on or before the date fixed for redemption.

14

The bonds of the One Hundred Fourth Series shall be redeemed, in whole at any time, or in part from time to time, prior to maturity, at a redemption price equal to the principal amount thereof, upon receipt by the Trustee of a written notice from the Collateral Trust Trustee (i) delivered to the Trustee and the Company, (ii) signed by its President, a Vice President, an Assistant Vice President or a Trust Officer, (iii) stating that an Event of Default has occurred and is continuing under the Collateral Trust Mortgage and that, as a result, there then is due and payable a specified amount with respect to the Securities Outstanding under the Collateral Trust Mortgage, for the payment of which the Collateral Trust Trustee has not received funds, and (iv) specifying the principal amount of the bonds of the One Hundred Fourth Series to be redeemed. Delivery of such notice shall constitute a waiver by the Collateral Trust Trustee of notice of redemption under the Mortgage.

(II) The bonds of the One Hundred Fourth Series shall not be transferable by the Collateral Trust Trustee, except to a successor trustee under the Collateral Trust Mortgage. Bonds of this series so transferable to a successor trustee under the Collateral Trust Mortgage may be transferred by the registered owner thereof, in person, or by his duly authorized attorney, at the office or agency of the Company in the Borough of Manhattan, The City of New York, in the manner prescribed in the Mortgage.

At the option of the registered owner, any bonds of the One Hundred Fourth Series, upon surrender thereof for cancellation at the office or agency of the Company in the Borough of Manhattan, The City of New York, shall be exchangeable for a like aggregate principal amount of bonds of the One Hundred Fourth Series of other authorized denominations.

Upon any exchange or transfer of bonds of the One Hundred Fourth Series, the Company may make a charge therefor sufficient to reimburse it for any tax or taxes or other governmental charge, as provided in Section 12 of the Mortgage, but the Company hereby waives any right to make a charge in addition thereto for any exchange or transfer of bonds of said Series.

(III) Upon the delivery of this Ninety-ninth Supplemental Indenture and upon compliance with the applicable provisions of the Mortgage, as heretofore supplemented, there shall be an initial issue of bonds of the One Hundred Fourth Series in the aggregate principal amount of $700,000,000. Additional bonds of the One Hundred Fourth Series, without limitation as to amount, having substantially the same terms as the Outstanding bonds of the One Hundred Fourth Series (except for the issue date and, if applicable, the initial Interest Payment Date) may be issued by the Company, subject to satisfaction of the requirements of the Mortgage, as heretofore supplemented, without notice to or the consent of the existing holders of the bonds of the One Hundred Fourth Series.

ENTERGY LOUISIANA, LLC

ENTERGY LOUISIANA, LLC, a limited liability company of the State of Texas (hereinafter called the “Company”), for value received, hereby promises to pay to THE BANK OF NEW YORK MELLON, as trustee under the Mortgage and Deed of Trust of the Company, dated as of November 1, 2015 (as the same may be supplemented and amended from time to time, the “Collateral Trust Mortgage”), or its successor as trustee under the Collateral Trust Mortgage, on September 15, 2034, 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, and to pay to the registered owner hereof interest thereon from August 9, 2024, if the date of this bond is prior to March 15, 2025, or if the date of this bond is on or after March 15, 2025, from the March 15 or September 15 immediately preceding the date of this bond to which interest has been paid on the bonds of this series (unless the date hereof is an interest payment date to which interest has been paid, in which case from the date hereof), at the rate of 5.15% per annum in like coin or currency at said office or agency on March 15 and September 15 of each year, commencing March 15, 2025 until the principal of this bond shall have become due and payable, and to pay interest on any overdue principal and (to the extent that payment of such interest is enforceable under applicable law) on any overdue installment of interest at the rate of 6% per annum. Interest hereon shall be paid to the Person in whose name this bond is registered.

Interest on the bonds of this 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 the maturity date of any bond of this series shall not be a Business Day, then payment of interest or principal and premium, if any, 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, 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 the maturity date, 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 Trustee is closed for business.

This bond is a temporary bond and is one of an issue of bonds of the Company issuable in series and is one of a series known as its First Mortgage Bonds, 5.15% Series due September 15, 2034, all bonds of all series issued and to be issued under and equally secured (except insofar as any sinking or other fund, established in accordance with the provisions of the Mortgage hereinafter mentioned, may afford

A-1

additional security for the bonds of any particular series) by the Company’s Mortgage and Deed of Trust (herein, together with any indenture supplemental thereto, including the Ninety-ninth Supplemental Indenture dated as of August 1, 2024, called the “Mortgage”), dated as of April 1, 1944, executed by the Company to The Bank of New York Mellon, successor trustee (the “Trustee”). Reference is made to the Mortgage for a description of the property mortgaged and pledged, the nature and extent of the security, the rights of the holders of the bonds and of the Trustee in respect thereof, the duties and immunities of the Trustee, the terms and conditions upon which the bonds are and are to be secured, the circumstances under which additional bonds may be issued and the rights of the Company to amend the Mortgage without any consent or other action by the holders of any series of bonds (including this series). With the consent of the Company and to the extent permitted by and as provided in the Mortgage, the rights and obligations of the Company and/or the rights of the holders of the bonds and/or coupons and/or the terms and provisions of the Mortgage may be modified or altered by such affirmative vote or votes of the holders of bonds then outstanding as are specified in the Mortgage. Each initial and future holder of the bonds of this series, by its acquisition of an interest in such bonds, irrevocably (a) consents to the amendments set forth in Sections 1 and 3 of Article II of the Eighty-first Supplemental Indenture without any other or further action by any holder of such bonds, and (b) designates 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 bondholder meeting, in lieu of any bondholder meeting, in any consent solicitation or otherwise.

The bonds of this series shall be issued by the Company, registered in the name of and delivered to The Bank of New York Mellon, as trustee under the Collateral Trust Mortgage, or its successor as trustee under the Collateral Trust Mortgage (collectively, the “Collateral Trust Trustee”), to provide for the payment when due (whether at maturity, by acceleration or otherwise) of the principal and interest of the Securities (as defined in the Collateral Trust Mortgage) to be issued from time to time under the Collateral Trust Mortgage.

Any payment by the Company under the Collateral Trust Mortgage of the principal of or interest on the Securities which shall have been authenticated and delivered under the Collateral Trust Mortgage on the basis of the issuance and delivery to the Collateral Trust Trustee of bonds of this series (other than by application of the proceeds of a payment in respect of such bonds) shall, to the extent of such payment, be deemed to satisfy and discharge the obligation of the Company, if any, to make a payment of principal of, or interest on such bonds, as the case may be, which is then due.

The Trustee may conclusively presume that the obligation of the Company to pay the principal of and interest on this bond as the same shall become due and payable shall have been fully satisfied and discharged unless and until it shall have received a written notice from the Collateral Trust Trustee signed by its President, a Vice President, an Assistant Vice President or a Trust Officer, stating that interest or principal due and payable on any Securities issued under the Collateral Trust Mortgage has not been fully paid and specifying the amount of funds required to make such payment.

The holder of this bond hereby consents that the bonds of this series may be redeemable at the option of the Company or pursuant to the requirements of the Mortgage in whole at any time, or in part from time to time, prior to the maturity date, without notice provided in Section 52 of the Mortgage, at the principal amount of the bonds to be redeemed, in each case, together with accrued interest to the date fixed for redemption by the Company in a notice delivered to the Trustee and to the holder of the bonds to be redeemed on or before the date fixed for redemption.

A-2

The bonds of this series shall be redeemed, in whole at any time, or in part from time to time, prior to the maturity date, at a redemption price equal to the principal amount thereof, upon receipt by the Trustee of a written notice from the Collateral Trust Trustee (i) delivered to the Trustee and the Company, (ii) signed by its President, a Vice President, an Assistant Vice President or a Trust Officer, (iii) stating that an Event of Default has occurred and is continuing under the Collateral Trust Mortgage and that, as a result, there then is due and payable a specified amount with respect to the Securities Outstanding under the Collateral Trust Mortgage, for the payment of which the Collateral Trust Trustee has not received funds, and (iv) specifying the principal amount of the bonds of this series to be redeemed. Delivery of such notice shall constitute a waiver by the Collateral Trust Trustee of notice of redemption under the Mortgage.

The principal hereof may be declared or may become due prior to the maturity date hereinbefore named on the conditions, in the manner and at the time set forth in the Mortgage, upon the occurrence of a default as in the Mortgage provided.

This bond is not transferable except to any successor trustee under the Collateral Trust Mortgage, any such transfer to be made in the manner prescribed in the Mortgage, by the registered owner hereof in person, or by his duly authorized attorney, at the office or agency of the Company in the Borough of Manhattan, The City of New York, upon surrender and cancellation of this bond, together with a written instrument of transfer whenever required by the Company duly executed by the registered owner or by his duly authorized attorney, and thereupon a new fully registered bond of the same series for a like principal amount will be issued to the transferee in exchange herefor as provided in the Mortgage.

The Company and the Trustee 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 Trustee shall be affected by any notice to the contrary.

In the manner prescribed in the Mortgage, any bonds of this series, upon surrender thereof, for cancellation, at the office or agency of the Company in the Borough of Manhattan, The City of New York, are exchangeable for a like aggregate principal amount of bonds of the same series of other authorized denominations.

Upon any transfer or exchange of bonds of this series, the Company may make a charge therefor sufficient to reimburse it for any tax or taxes or other governmental charge, as provided in Section 12 of the Mortgage, but the Company hereby waives any right to make a charge in addition thereto for any exchange or transfer of bonds of this series.

In the manner prescribed in the Mortgage, this temporary bond is exchangeable at the office or agency of the Company in the Borough of Manhattan, The City of New York, without charge, for a definitive bond or bonds of the same series of a like aggregate principal amount when such definitive bonds are prepared and ready for delivery.

A-3

As provided in the Mortgage, the Company shall not be required to make transfers or exchanges of bonds of any series for a period of ten days next preceding any interest payment date for bonds of said series, or next preceding any designation of bonds of said series to be redeemed, and the Company shall not be required to make transfers or exchanges of any bonds designated in whole or in part for redemption.

No recourse shall be had for the payment of the principal of or interest on this bond against any incorporator or any past, present or future subscriber to the capital stock, stockholder, officer or director of the Company or of any predecessor or successor corporation, as such, either directly or through the Company or any predecessor or successor corporation, under any rule of law, statute or constitution or by the enforcement of any assessment or otherwise, all such liability of incorporators, subscribers, stockholders, officers and directors being released by the holder or owner hereof by the acceptance of this bond and being likewise waived and released by the terms of the Mortgage.
