NOW, THEREFORE, in consideration of the premises and of the mutual covenants herein contained and for other valuable consideration, the receipt whereof is hereby acknowledged, the parties have executed and delivered this Twelfth Supplemental Indenture and the Company covenants and agrees with the Trustee as follows:

Article 1

5.05% Senior Notes Due 2052

Section 101. Establishment. There is hereby established a new series of Debt Securities to be issued under the Indenture, to be designated as the Company’s 5.05% Senior Notes Due 2052 (the “Notes”).

There are to be initially authenticated and delivered $400,000,000 aggregate principal amount of Notes; provided, however, that the authorized aggregate principal amount of the Notes may be increased above such amount without the consent of the Holders of any then outstanding Notes by a Board Resolution authorizing such increase; provided, however, that such additional Notes issued pursuant to such increase will be fungible with the initially issued Notes for U.S. Federal income tax purposes, and any such additional Notes issued in this manner will be consolidated with, and will form a single series with, the initially issued Notes. The Notes shall be issued in definitive fully registered form.

The Notes shall be issued in the form of a Book-Entry Debt Security in substantially the form set out in Exhibit A hereto. The Depository with respect to the Notes shall be The Depository Trust Company.

The form of the Trustee’s Certificate of Authentication for the Notes shall be in substantially the form set forth in Exhibit B hereto.

Each Note shall be dated the date of authentication thereof and shall bear interest from the date of original issuance thereof or from the most recent Interest Payment Date to which interest has been paid or duly provided for.

Section 102. Definitions. The following defined terms used herein shall, unless the context otherwise requires, have the meanings specified below. Capitalized terms used herein for which no definition is provided herein shall have the meanings set forth in the Original Indenture.

“Interest Payment Dates” means May 15 and November 15 of each year, commencing November 15, 2022.

“Original Issue Date” means May 13, 2022.

“Par Call Date” means November 15, 2051.

“Stated Maturity” means May 15, 2052.

“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:

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

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

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 clause, 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. 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.

The Trustee shall have no obligation or duty whatsoever to determine, or to verify our calculations of, the redemption price.

Section 103. Payment of Principal and Interest. The principal of the Notes shall be due at the Stated Maturity (unless earlier redeemed). The unpaid principal amount of the Notes shall bear interest at the rate of 5.05% per annum until paid or duly provided for. Interest shall be paid semi-annually in arrears on each Interest Payment Date to the Persons in whose name each Note is registered at the close of business on the Record Date for the applicable Interest Payment Date, which will be the close of business on (i) the Business Day immediately preceding such Interest Payment Date so long as all of the Notes remain in the form of a Book-Entry Debt Security or (ii) the fifteenth calendar day next preceding such Interest Payment Date (whether or not such day is a Business Day) if any of the Notes do not remain in the form of a Book-Entry Debt Security, provided that interest payable at the Stated Maturity of principal or on a redemption date as provided herein will be paid to the Person to whom principal is payable. Any such interest that is not so punctually paid or duly provided for will forthwith cease to be payable to the Holders on such Record Date and will be paid to the Person in whose name the Notes are registered on a subsequent Record Date established for the payment of such defaulted interest by notice given by mail or on behalf of the Company to the Holders no less than fifteen (15) days preceding such subsequent Record Date, such Record Date to be not less than five (5) days preceding the date of payment of such defaulted interest or in any other lawful manner acceptable to the Trustee.

Payments of interest on the Notes will include interest accrued to but excluding the respective Interest Payment Dates. Interest payments for the Notes shall be computed and paid on the basis of a 360-day year of twelve 30-day months (and for any partial periods shall be calculated on the basis of the number of days elapsed in a 360-day year of twelve 30-day months). In the event that any date on which interest or principal is payable on the Notes is not a Business Day, then payment of the interest or principal payable on such date, as applicable, will be made on the next succeeding day that is a Business Day (and without any additional interest or other payment in respect of any such delay), with the same force and effect as if made on the date the payment was originally payable.

Payment of the principal and interest due at the Stated Maturity or earlier redemption of the Notes shall be made upon surrender of the Notes at the Corporate Trust Office of the Trustee. The principal of and interest on the Notes shall be paid 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. Payments of the principal and interest (including interest on any Interest Payment Date) will be made, subject to such surrender where applicable, at the option of the Company, (i) by wire transfer to the Holders entitled thereto who have provided appropriate wire transfer instructions to the Trustee, or by check mailed to the Holders of the Notes entitled thereto at their last addresses as they appear on the Debt Security Register or (ii) if the Notes are Book-Entry Debt Securities, the Depository, as Holder of the Notes, shall be entitled to receive payment of interest by wire transfer of immediately available funds.

Section 104. Denominations. The Notes may be issued in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

Section 105. Book-Entry Debt Securities. The Notes will be issued in the form of a Book-Entry Debt Security registered in the name of the Depository or its nominee. Except under the limited circumstances described below, Notes represented by the Book-Entry Debt Security will not be exchangeable for, and will not otherwise be issuable as, Notes in definitive, non-global form. The Book-Entry Debt Securities described above may not be transferred except by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository or to a successor Depository or its nominee.

Owners of beneficial interests in such a Book-Entry Debt Security will not be considered the Holders thereof for any purpose under the Indenture, and no Book-Entry Debt Security representing a Note shall be exchangeable, except for another Book-Entry Debt Security of like denomination and tenor to be registered in the name of the Depository or its nominee or to a successor Depository or its nominee. The rights of Holders of such Book-Entry Debt Security shall be exercised only through the Depository.

Subject to the procedures of the Depository, a Book-Entry Debt Security shall be exchangeable for Notes registered in the names of persons other than the Depository or its nominee only if (i) the Depository notifies the Company that it is unwilling or unable to continue as a Depository for such Book-Entry Debt Security and no successor Depository shall have been appointed by the Company, or if at any time the Depository ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended, at a time when the Depository is required to be so registered to act as such Depository and no successor Depository shall have been appointed by the Company, in each case within 60 days after the Company receives such notice or becomes aware of such cessation, (ii) the Company in its sole discretion determines that such Book-Entry Debt Security shall be so exchangeable, or (iii) there shall have occurred an Event of Default with respect to the Notes. Any Book-Entry Debt Security that is exchangeable pursuant to the preceding sentence shall be exchangeable for Notes registered in such names as the Depository shall direct.

Section 106. Transfer. No service charge will be made for the exchange or to register a transfer of Notes, but payment will be required of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith.

The Company shall not be required to exchange or register a transfer of (a) Notes for a period of fifteen (15) days next preceding the mailing of the notice of any redemption of Notes to be redeemed, or (b) Notes selected, called or being called for redemption, except, in the case of Notes to be redeemed in part, the portion thereof not to be so redeemed.

Section 107. Redemption at the Company’s Option. Prior to the Par Call Date, the Company may redeem the Notes at its option, in whole or in part, 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: (i)(a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the Notes 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 30 basis points less (b) interest accrued to the redemption date; and (ii) 100% of the principal amount of the Notes to be redeemed, plus, in each case, accrued and unpaid interest thereon to, but excluding, the redemption date.

On or after the Par Call Date, the Company may redeem the Notes at its option, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest thereon to, but excluding, the redemption date.

Notwithstanding the foregoing, installments of interest on the Notes that are due and payable on an Interest Payment Date falling on or prior to a redemption date shall be payable on such Interest Payment Date to the Holders as of the close of business on the relevant Record Date.

On or after the date of redemption, interest will cease to accrue on the Notes or portion of the Notes redeemed. However, interest will continue to accrue if the Company defaults in the payment of the amount due upon redemption.

Notice of redemption to each Holder of the Notes shall be mailed (or, as long as the Notes of this series are represented by one or more Book-Entry Debt Securities, transmitted in accordance with the Depository’s standard procedures therefor) by the Company, or, at the Company’s request, by the Trustee, in the manner provided in Section 3.02 of the Original Indenture, at least ten (10) and not more than sixty (60) days prior to the date fixed for redemption.
