I.

NINETY-FIRST SERIES OF BONDS

SECTION 1. There shall be a series of bonds designated “5.15% Series due January 15, 2033” (herein sometimes called the “Ninety-first Series”), each of which shall also bear the descriptive title “First Mortgage Bond,” and the form thereof, which shall be established by Resolution of the Board of Directors of the Company, shall contain suitable provisions with respect to the matters hereinafter in this Section specified. Bonds of the Ninety-first Series (which shall be initially issued in the aggregate principal amount of $425,000,000) shall mature on January 15, 2033, shall be issued as fully registered bonds in the denomination of One thousand Dollars and, at the option of

- 13 -

the Company, in any multiple or multiples of One thousand Dollars (the exercise of such option to be evidenced by the execution and delivery thereof), shall bear interest at the rate of 5.15% per annum, the first interest payment to be made on July 15, 2023, for the period from January 6, 2023 to July 15, 2023 with subsequent interest payments payable semi-annually in arrears on January 15 and July 15 of each year (each an “Interest Payment Date”), shall be dated as in Section 10 of the Mortgage provided, and the principal of and interest on each said bond shall be payable at the office or agency of the Company in the Borough of Manhattan, The City of New York, in such coin or currency of the United States of America as at the time of payment is legal tender for public and private debts.

Interest on the bonds of the Ninety-first Series will be computed on the basis of a 360-day year of twelve 30-day months. In any case where any Interest Payment Date, redemption date or maturity of any bond of the Ninety-first Series shall not be a Business Day, then payment of interest or principal need not be made on such date, but may be made on the next succeeding Business Day, with the same force and effect, and in the same amount, as if made on the corresponding Interest Payment Date or redemption date, or at maturity, as the case may be, and, if such payment is made or duly provided for on such Business Day, no interest shall accrue on the amount so payable for the period from and after such Interest Payment Date, redemption date or maturity, as the case may be, to such Business Day. “Business Day” means any day, other than a Saturday or a Sunday, or a day on which banking institutions in The City of New York are authorized or required by law or executive order to remain closed or a day on which the corporate trust office of the Corporate Trustee is closed for business.

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

(I) Form of Bonds of the Ninety-first Series.

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

DEUTSCHE BANK TRUST COMPANY AMERICAS, as Corporate Trustee
By:
	Authorized Officer

(II) Prior to October 15, 2032 (the “Par Call Date”), the bonds of the Ninety-first Series shall be redeemable at the option of the Company, in whole or in part, upon notice, mailed not less than 30 days nor more than 60 days 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:

(1) (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 of the Ninety-first Series 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 Redemption Date, and

(2) 100% of the principal amount of the bonds of the Ninety-first Series being redeemed,

- 18 -

plus, in either case, accrued and unpaid interest on the bonds of the Ninety-first Series being redeemed to, but not including, the Redemption Date.

On or after the Par Call Date, the bonds of the Ninety-first Series will be redeemable at the option of the Company, in whole or in part, on not less than 30 nor more than 60 days’ notice, at any time and from time to time, at a Redemption Price equal to 100% of the principal amount of the bonds of the Ninety-first Series being redeemed plus accrued and unpaid interest thereon to, but not including, 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.

- 19 -

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

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

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

(3) if there are two or more United States Treasury securities meeting the criteria of the preceding clauses (1) or (2), the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time.

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.

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

(III) At the option of the registered owner, any bonds of the Ninety-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 of other authorized denominations.

- 20 -

Bonds of the Ninety-first Series shall be transferable, upon the surrender thereof for cancellation, together with a written instrument of transfer in form approved by the registrar duly executed by the registered owner 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 any exchange or transfer of bonds of the Ninety-first 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.

Upon the delivery of this Eighty-fifth 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 Ninety-first Series for the aggregate principal amount of $425,000,000. Additional bonds of the Ninety-first Series, without limitation as to amount, having substantially the same terms as the Outstanding bonds of the Ninety-first Series (except for the issue date, price to public and, if applicable, the initial interest payment date) may be issued by the Company without the notice to or the consent of the existing holders of the bonds of the Ninety-first Series.

A conveyance, transfer, or lease by the Company of any part of the Mortgaged and Pledged Property shall not be deemed to constitute the conveyance, transfer or lease of all or substantially all of the Mortgaged and Pledged Property for purposes of this Indenture if the fair value of the Mortgaged and Pledged Property retained by the Company exceeds 167% of the aggregate principal amount of all Outstanding bonds issued under this Indenture and any other outstanding debt of the Company secured by a purchase money lien that ranks equally with, or senior to, such bonds with respect to such Mortgaged and Pledged Property. Such fair value shall be established by the delivery to the Corporate Trustee of an Independent Engineer’s Certificate stating the Independent Engineer’s opinion of such fair value as of a date not more than 90 days before or after such conveyance, transfer or lease. Article XVI of this Indenture is not intended to limit the Company’s conveyances, transfers or leases of less than substantially all of the Mortgaged and Pledged Property. This paragraph is not intended to create an inference that any conveyance, transfer or lease of any part of the Mortgaged and Pledged Property shall necessarily be deemed to constitute a conveyance, transfer, or lease of all or substantially all of the Mortgaged and Pledged Property for purposes of this Indenture where the fair value of the Mortgaged and Pledged Property retained by the Company is less than 167% of the aggregate principal amount of all Outstanding bonds and any other outstanding debt of the Company secured by a purchase money lien that ranks equally with, or senior to, such bonds with respect to such Mortgaged and Pledged Property.

SECTION 4. Merger into Company; Extent of Lien of the Indenture. The holders of a majority in principal amount of the bonds Outstanding under the Mortgage having consented to the amendment set forth in Section 4 of Article II of the Eightieth Supplemental Indenture, the Company hereby exercises its right to amend the Mortgage, as heretofore amended and supplemented, to add the following new paragraph to the end of Section 87 thereof reading as follows:

In the case of a consolidation or merger after the consummation of which the Company would be the surviving or resulting entity, unless an indenture supplemental hereto shall otherwise provide, this Indenture shall not become or be, or be required to become or be, a lien upon any of the properties acquired by the Company in or as a result of such transaction or any improvements, extensions, or additions to such properties or any renewals, replacements, or substitutions of or for any part or parts thereof.

SECTION 5. Limitation on Bondholder Suits. The holders of a majority in principal amount of the bonds Outstanding under the Mortgage having consented to the amendment set forth in Section 5 of Article II of the Eightieth Supplemental Indenture, the Company hereby exercises its right to amend Section 80 of the Mortgage to change the word “hereunder” wherever it appears in the first paragraph of Section 80 of the Mortgage to “under or with respect to this Indenture or the bonds.
