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

ARTICLE I

Fifty-First Series of Bonds

SECTION 1.01. There shall be a series of bonds designated “5.500% Series due 2054” (herein sometimes referred to as the Fifty-First Series), each of which shall also bear the descriptive title “First Mortgage Bond,” and the form thereof, which shall be established by or pursuant to a Resolution, shall contain suitable provisions with respect to the matters hereinafter in this Section specified.

(I) Bonds of the Fifty-First Series shall mature on May 15, 2054 and shall be issued as fully registered bonds in the minimum denomination of two thousand dollars and, at the option of the Company, any multiple or multiples of one thousand dollars in excess thereof (the exercise of such option to be evidenced by the execution and delivery thereof).

The Company reserves the right to establish, at any time, by or pursuant to a Resolution filed with the Trustee, a form of coupon bond, and or appurtenant coupons, for the Fifty-First Series and to provide for exchangeability of such coupon bonds with the bonds of the Fifty-First Series issued hereunder in fully registered form and to make all appropriate provisions for such purpose.

Bonds of the Fifty-First Series need not be issued at the same time and such series may be reopened at any time, without notice to or the consent of any then-existing holder or holders of any bond of the Fifty-First Series, for issuances of additional bonds of the Fifty-First Series in an unlimited principal amount. Any such additional bonds will have the same interest rate, maturity and other terms as those initially issued, except for payment of interest accruing prior to the original issue date of such additional bonds and, if applicable, for the first interest payment date following such original issue date.

(II) Bonds of the Fifty-First Series shall bear interest at the rate of five and a half per centum (5.500%) per annum payable semi-annually in arrears on May 15 and November 15 of each year (each, an “Interest Payment Date”). Bonds of the Fifty-First Series shall be dated and shall accrue interest as provided in Section 2.06 of the Mortgage.

The initial Interest Payment Date is November 15, 2023. The amount of interest payable will be computed on the basis of a 360-day year consisting of twelve 30-day months. If any date on which interest is payable on any bond of the Fifty-First Series is not a Business Day, then payment of the interest payable on that date will be made on the next succeeding day which is a Business Day (and without any additional interest or other payment in respect of any delay), with the same force and effect as if made on such date.

Interest payable on any bond of the Fifty-First Series and punctually paid or duly provided for on any Interest Payment Date for such bond will be paid to the person in whose name the bond is registered at the close of business on the Record Date (as hereinafter specified) for such bond next preceding such Interest Payment Date; provided, however, that interest payable at maturity or upon earlier redemption will be payable to the person to whom principal shall be payable. So long as the bonds of the Fifty-First Series remain in book-entry only form, the “Record Date” for each Interest Payment Date shall be the close of business on the Business Day before the applicable Interest Payment Date. If the bonds of the Fifty-First Series are not in book-entry only form, the Record Date for each Interest Payment Date shall be the close of business on the 1st calendar day of the month in which the applicable Interest Payment Date occurs (whether or not a Business Day).

“Business Day” means, for purposes of this Section (II), a day other than (i) a Saturday or a Sunday, or (ii) a day on which banking institutions in The City of New York are authorized or obligated by law or executive order to remain closed.

Any interest on any bond of the Fifty-First Series which is payable but is not punctually paid or duly provided for, on any Interest Payment Date for such bond (herein called “Defaulted Interest”), shall forthwith cease to be payable to the registered owner on the relevant Record Date for the payment of such interest solely by virtue of such owner having been such owner; and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in subsection (i) or (ii) below:


			(i)			The Company may elect to make payment of any Defaulted Interest on the bonds of the Fifty-First Series to the persons in whose names such bonds are registered at the close of business on a Special Record Date (as hereinafter defined) for the payment of such Defaulted Interest, which shall be fixed in the following manner: The Company shall, at least 30 days prior to the proposed date of payment, notify the Trustee in writing (signed by an Authorized Financial Officer of the Company) of the amount of Defaulted Interest proposed to be paid on each bond of the Fifty-First Series and the date of the proposed payment (which date shall be such as will enable the Trustee to comply with the next sentence hereof), and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the persons entitled to such Defaulted Interest as in this subsection provided and not to be deemed part of the Mortgaged and Pledged Property. Thereupon, the Trustee shall fix a record date (herein referred to as a “Special Record Date”) for the payment of such Defaulted Interest which date shall be not more than 15 nor less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each registered owner of a bond of the Fifty-First Series at his, her or its address as it appears in the bond register not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the persons in whose names the bonds of the Fifty-First Series are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following subsection (ii).
			(ii)			The Company may make payment of any Defaulted Interest on the bonds of the Fifty-First Series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such bonds may be listed and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this subsection, such payment shall be deemed practicable by the Trustee.

Subject to the foregoing provisions of this Section, each bond of the Fifty-First Series delivered under the Mortgage upon transfer of or in exchange for or in lieu of any other bond shall carry all rights to interest accrued and unpaid, and to accrue, which were carried by such other bond and each such bond shall bear interest from such date, that neither gain nor loss in interest shall result from such transfer, exchange or substitution.

(III) The principal of and interest and premium, if any, on each bond of the Fifty-First Series shall be payable at the office or agency of the Company in the Borough of Manhattan, The City of New York, in such coin or currency of the United States of America as at the time of payment is legal tender for public and private debts or in such other currency or currency unit as shall be determined by or in accordance with the Resolution filed with the Trustee.

(IV) Bonds of the Fifty-First Series shall not be redeemable prior to maturity at the option of any holder or holders of such bonds. Bonds of the Fifty-First Series shall be redeemable, in whole or in part, at any time and from time to time prior to maturity at the option of the Company. Prior to November 15, 2053 (six months prior to their maturity date) (the “par call date”), the redemption price (expressed as a percentage of principal amount and rounded to three decimal places) shall include accrued and unpaid interest to the redemption date on the bonds to be redeemed, plus the greater of (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the bonds matured on the par call date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 25 basis points less (b) interest accrued to the date of redemption. On or after the par call date, the redemption price shall be equal to one hundred percent (100%) of the principal amount of bonds of this series then Outstanding to be redeemed, plus accrued and unpaid interest thereon to the redemption date.

“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: (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, 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 of the United States Treasury security maturing on, or with a maturity that is closest to, the par call date, as applicable. If there is no United States Treasury security maturing on the par call date but there are two or more United States Treasury securities with a maturity date equally distant from the par call date, one with a maturity date preceding the par call date and one with a maturity date following the par call date, the Company shall select the United States Treasury security with a maturity date preceding the par call date. If there are two or more United States Treasury securities maturing on the par call date or two or more United States Treasury securities meeting the criteria of the preceding sentence, 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. 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 (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

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

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the redemption date to each holder of bonds to be redeemed at its registered address.

In the case of a partial redemption, selection of the bonds for redemption will be made by lot. No bonds of a principal amount of $2,000 or less will be redeemed in part. If any bond is to be redeemed in part only, the notice of redemption that relates to the bond will state the portion of the principal amount of the bond to be redeemed. A new bond in

a principal amount equal to the unredeemed portion of the bond will be issued in the name of the holder of the bond upon surrender for cancellation of the original bond. For so long as the bonds are held by The Depository Trust Company (or another depositary), the redemption of the bonds shall be done in accordance with the policies and procedures of the depositary.

Unless the Company defaults in payment of the redemption price, on and after the redemption date interest will cease to accrue on the bonds or portions thereof called for redemption.

(V) Each bond of the Fifty-First Series may have such other terms as are not inconsistent with Section 2.03 of the Mortgage, and as may be determined by or in accordance with a Resolution filed with the Trustee.

(VI) At the option of the registered owner, any bonds of the Fifty-First 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 same series and same terms of other authorized denominations.

(VII) Bonds of the Fifty-First Series shall be transferable, subject to any restrictions thereon set forth in any such bond of the Fifty-First Series, upon the surrender thereof for cancellation, together with a written instrument of transfer, if required by the Company, duly executed by the registered owner or by his, her or its duly authorized attorney, at the office or agency of the Company in the Borough of Manhattan, The City of New York. Upon any transfer or exchange of bonds of the Fifty-First Series, the Company may make a charge therefor sufficient to reimburse it for any tax or taxes or other government charge, as provided in Section 2.08 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 the Fifty-First Series.

(VIII) After the execution and delivery of this Thirty-Fourth Supplemental Indenture and upon compliance with the applicable provisions of the Mortgage and this Thirty-Fourth Supplemental Indenture, it is contemplated that there shall be issued bonds of the Fifty-First Series in an initial aggregate principal amount of One Billion Two Hundred Million Dollars (U.S. $1,200,000,000).
