NOTES

SECTION 1.01. Definitions.

Unless the context otherwise requires or unless otherwise set forth herein:

(a) a term not defined herein that is defined in the Original Indenture has the same meaning when used in this Tenth Supplemental Indenture;

(b) the definition of any term in this Tenth Supplemental Indenture that is also defined in the Original Indenture shall for the purposes of this Tenth Supplemental Indenture supersede the definition of such term in the Original Indenture;

(c) a term defined anywhere in this Tenth Supplemental Indenture has the same meaning throughout this Tenth Supplemental Indenture;

(d) the definition of a term in this Tenth Supplemental Indenture is not intended to have any effect on the meaning or definition of an identical term that is defined in the Original Indenture, insofar as the use or effect of such term in the Original Indenture, as previously defined, is concerned;

(e) the singular includes the plural and vice versa;

(f) headings are for convenience of reference only and do not affect interpretation; and

(g) the following terms have the meanings given to them in this Section 1.01(g):

“Business Day” means any day other than a day on which the federal or state banking institutions in the Borough of Manhattan, The City of New York or a place of payment, are authorized or obligated by law, executive order or regulation to close.

“Interest Payment Date” means May 19 and November 19 of each year, commencing November 19, 2025.

“IRS” means the Internal Revenue Service of the United States of America.

“Original Issue Date” means May 19, 2025.

“Par Call Date” means November 19, 2054.

“Redemption Date” means the date fixed for the redemption of the Notes by or pursuant to the Indenture.

“Regular Record Date” means, with respect to each Interest Payment Date, the close of business on the preceding May 1 or November 1, as the case may be (whether or not a Business Day).

“Restricted Subsidiary” has the meaning set forth in Section 1.09(a) of this Tenth Supplemental Indenture.

“Stated Maturity Date” means May 19, 2055.

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

3

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 or any successor designation or publication 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.

SECTION 1.02. Establishment.

(a) There is hereby established a new series of Securities to be issued under the Indenture, to be designated as the Company’s 6.625% Senior Notes due 2055.

4

(b) There are to be authenticated and delivered the Notes, initially limited in aggregate principal amount to $1,000,000,000, and no further Notes shall be authenticated and delivered except as provided by Sections 2.05, 2.07, 2.11, 3.03 or 9.04 of the Original Indenture; provided, however, that the aggregate principal amount of the Notes may be increased in the future with no limit, without the consent of the holders of the Notes, on the same terms and with the same CUSIP and ISIN numbers as the Notes, except for the issue price, Original Issue Date and, if applicable, the first Interest Payment Date and the initial interest accrual date; provided that no Event of Default with respect to the Notes shall have occurred and be continuing. The Notes shall be issued in fully registered form. Any additional Notes having such similar terms shall constitute a single series of debt securities with the Notes under the Indenture. Notwithstanding the foregoing, if any of such additional Notes are not issued in a “qualified reopening” or are not treated as part of the same issue as the Notes for U.S. federal income tax purposes, such additional Notes shall have a separate CUSIP and ISIN number.

(c) The Notes shall be issued in the form of one or more Global Securities, registered in the name of the Depositary or its nominee. Each Global Security and the Trustee’s certificate of authentication thereof shall be in substantially the form set forth in Exhibit A hereto.

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

SECTION 1.03. Payment of Principal and Interest.

(a) The principal amount of the Notes shall be due at the Stated Maturity Date. The unpaid principal amount of the Notes shall bear interest at the rate of 6.625% per year until paid or duly provided for. Interest on the Notes shall be paid semi-annually in arrears on each Interest Payment Date, commencing November 19, 2025, to the Person in whose name the Notes are registered on the Regular Record Date for such Interest Payment Date; provided that interest payable at the Stated Maturity Date or upon redemption shall be paid to the Person to whom principal is payable. Any such interest that is not so punctually paid or duly provided for shall forthwith cease to be payable to the holders on such Regular Record Date and may be paid as provided in Section 2.03 of the Original Indenture.

(b) Payments of interest on the Notes shall include interest accrued to but excluding the respective Interest Payment Date. Interest payments for the Notes shall be computed and paid on the basis of a 360-day year consisting of twelve 30-day months.

(c) In the event that any date on which interest is payable on the Notes is not a Business Day, then payment of the interest payable on such date shall be made on the next succeeding Business Day (and without any 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.

(d) The Trustee is hereby designated as Paying Agent for the Notes and all payments of the principal of, and premium, if any, and interest due on the Notes at the Stated Maturity Date or upon redemption shall be made upon surrender of the Notes at the Corporate Trust Office of the Trustee.

5

(e) The principal of, and premium, if any, and interest due 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 interest (including payments of interest on any Interest Payment Date) shall be made, subject to such surrender where applicable and subject, in the case of a Global Security, to the Trustee’s arrangements with the Depositary, at the option of the Company, (i) by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register, or (ii) by wire transfer at such place and to such account at a banking institution in the United States of America as may be designated in writing to the Trustee at least 15 days prior to the date for payment by the Person entitled thereto.

SECTION 1.04. Denominations. The Notes shall be issued in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

SECTION 1.05. Global Securities.

(a) Except under the limited circumstances described below, the Notes represented by Global Securities shall not be exchangeable for, and shall not otherwise be issuable as, Notes in definitive form. The Global Securities described above may not be transferred except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or to a successor Depositary or its nominee.

(b) Except as otherwise provided in this Tenth Supplemental Indenture, owners of beneficial interests in such Global Securities shall not be considered the holders thereof for any purpose under the Indenture, and no Global Security representing a Note shall be exchangeable, except for another Global Security of like denomination and to be registered in the name of the Depositary or its nominee or to a successor Depositary or its nominee. The rights of holders of such Global Securities shall be exercised only through the Depositary.

(c) A Global Security shall be exchangeable in whole or, from time to time, in part for Notes in definitive registered form only as provided in the Indenture. If (i) at any time the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for the Notes or if at any time the Depositary shall no longer be registered or in good standing as a “clearing agency” registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934, as amended, or other applicable statute or regulation, at such time as the Depositary is required to be so registered, and the Depositary so notifies the Company and, in each case, the Company does not appoint a successor Depositary within 90 days after the Company receives such notice or becomes aware of such condition, as the case may be, (ii) any Event of Default or Default has occurred and is continuing with respect to the Notes or (iii) subject to the procedures of the Depositary, the Company in its sole discretion determines that the Notes shall be exchangeable for Notes in definitive registered form and executes and, in each case, delivers to the Security Registrar a written order of the Company providing that the Notes shall be so exchangeable, the Notes shall be exchangeable for Notes in definitive registered form; provided that the definitive Notes so issued in exchange for the Notes shall be in minimum denominations of $2,000, or any integral multiple of $1,000 in excess thereof, and shall be of like aggregate principal amount and tenor as the portion of the Notes to be exchanged. Except as provided herein, owners of beneficial interests in the Notes shall not be entitled to have Notes registered in their names, shall not receive or be entitled to physical delivery of Notes in definitive registered form and shall not be considered the holders thereof for any purpose under the Indenture. Neither the Company, the Trustee, any Paying Agent nor the Security Registrar shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in the Notes, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. Any Global Security that is exchangeable pursuant to this Section 1.05(c) shall be exchangeable for Notes registered in such names as the Depositary shall direct.

6

SECTION 1.06. Transfer. The Trustee is hereby designated as Security Registrar for the Notes. No service charge shall be made for any registration of transfer or exchange of Notes, but payment may be required of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith.

SECTION 1.07. Defeasance. The provisions of Sections 13.02 and 13.03 of the Original Indenture shall apply to the Notes.

SECTION 1.08. Redemption at the Option of the Company.

(a) The provisions of Sections 3.01, 3.02 (subject to Section 1.08(d) hereof) and 3.03 of the Original Indenture shall apply to the Notes.

(b) Prior to the Par Call Date, the Company may redeem the Notes at its option, in whole or in part, for cash 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:

(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 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

(2) 100% of the principal amount of the Notes to be redeemed,

plus, in either case, accrued and unpaid interest thereon to, but excluding, the Redemption Date.

(c) On or after the Par Call Date, the Company may redeem the Notes, in whole or in part, for cash at any time and from time to time, at a Redemption Price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to, but excluding, the Redemption Date.

(d) The Company shall mail or caused to be mailed or electronically delivered (or transmitted in accordance with the Depositary’s standard procedures) at least 10 days, but not more than 60 days, before the Redemption Date, to each holder of Notes to be redeemed.

(e) The Company shall notify the Trustee of the Redemption Price with respect to any redemption pursuant to this Section 1.08 promptly after the calculation thereof. The Trustee shall not be responsible for calculating said Redemption Price.

(f) In the case of a partial redemption, selection of the Notes for redemption will be made pro rata, by lot or by such other method as the Trustee in its sole discretion deems appropriate and fair. No Notes of a principal amount of $2,000 or less will be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that relates to the Note will state the portion of the principal amount of the Note to be redeemed. A new Note in a principal amount equal to the unredeemed portion of the Note will be issued in the name of the holder of the Note upon surrender for cancellation of the original note. For so long as the Notes are held by DTC (or another Depositary), the redemption of the Notes shall be done in accordance with the policies and procedures of the Depositary.

7

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date interest will cease to accrue on the Notes or portions thereof called for redemption.

SECTION 1.09. Covenants.

(a) So long as any Notes are outstanding, neither the Company nor any of its subsidiaries shall create, assume, incur or guarantee any indebtedness for borrowed money which is secured by a mortgage, pledge, lien, security interest or other encumbrance on any capital stock of: (i) any subsidiary that, as of the end of the Company’s most recently completed fiscal year, was a Significant Subsidiary (as defined in Rule 1-02(w) of Regulation S-X promulgated by the Commission); and (ii) any successor to substantially all of the business of any subsidiary in clause (i) of this Section 1.09(a) which is also a Subsidiary of the Company (each person or successor referred to in clauses (i) and (ii) of this Section 1.09(a), a “Restricted Subsidiary”); provided, however, that this Section 1.09(a) shall not apply if the Notes then outstanding are secured at least equally and ratably with the secured and outstanding indebtedness otherwise prohibited by this Section 1.09(a). If the Company shall hereafter be required to secure the Notes equally and ratably with any other indebtedness pursuant to this Section 1.09(a), (i) the Company will promptly deliver to the Trustee an Officer’s Certificate stating that the foregoing covenant has been complied with and (ii) the Trustee is hereby authorized to enter into an indenture or agreement supplemental hereto and to take such action to enable it to enforce the rights of the holders of the Notes so secured.

(b) So long as any Notes are outstanding and subject to Article X of the Original Indenture, neither the Company nor any of its Subsidiaries shall sell or otherwise dispose of any shares of capital stock (other than preferred stock having no voting rights of any kind) of any Restricted Subsidiary except for: (i) a sale or other disposition of any of such stock to a wholly-owned subsidiary of the Company; (ii) a sale or other disposition of all of a Subsidiary’s stock for at least fair value (as determined by the Board of Directors acting in good faith); or (iii) a sale or other disposition required to comply with an order of a court or regulatory authority of competent jurisdiction, other than an order issued at the request of the Company or the request of any of the Company’s Subsidiaries.

(c) Clause (a) of Section 10.01 of the Original Indenture is amended by inserting the phrase “is a corporation organized and validly existing under the laws of the United States of America, any State thereof or the District of Columbia and” between the phrases “if other than the Company” and “shall expressly assume by an indenture supplemental hereto.”

SECTION 1.10. No Sinking Fund. None of the Notes shall be entitled to any sinking fund and the provisions of Section 3.04, 3.05 and 3.06 shall not apply to the Notes.
