CREATION, FORMS,

TERMS AND CONDITIONS OF THE SECURITIES

SECTION 2.01. Creation of the Notes. In accordance with Section 301 of the Original Indenture, the Company hereby creates the Notes as a separate series of its securities issued pursuant to the Indenture. The Notes shall be issued initially in an aggregate principal amount of $700,000,000, except as permitted by Sections 304, 305 or 306 of the Original Indenture.

5

SECTION 2.02. Form of the Notes. The Notes shall be issued in the form of one or more Global Notes, duly executed by the Company and authenticated by the Trustee, which shall be deposited with the Trustee as custodian for DTC and registered in the name of “Cede & Co.,” as the nominee of DTC. The Notes shall be substantially in the form of Exhibit A attached hereto. So long as DTC, or its nominee, is the registered owner of a Global Note, DTC or its nominee, as the case may be, shall be considered the sole owner or Holder of the Notes represented by such Global Note for all purposes under the Indenture. Ownership of beneficial interests in such Global Note shall be shown on, and transfers thereof will be effected only through, records maintained by DTC (with respect to beneficial interests of participants) or by participants or Persons that hold interests through participants (with respect to beneficial interests of beneficial owners).

SECTION 2.03. Terms and Conditions of the Notes. The Notes shall be governed by all the terms and conditions of the Original Indenture, as supplemented by this Tenth Supplemental Indenture. In particular, the following provisions shall be terms of the Notes:

(a) Title and Aggregate Principal Amount. The title of the Notes shall be as specified in the Recitals; and the aggregate principal amount of the Notes shall be as specified in Section 2.01 of this Article II, except as permitted by Sections 304, 305 or 306 of the Original Indenture.

(b) Stated Maturity. The Notes shall mature, and the unpaid principal thereon shall be payable, on September 15, 2034 (the “Maturity Date”), subject to the provisions of the Original Indenture and Articles III and IV below.

(c) Interest. The rate per annum at which interest shall be payable on the Notes shall be 5.200%. Interest on the Notes shall be payable semi-annually in arrears on each March 15 and September 15, commencing on March 15, 2025 (each, an “Interest Payment Date”), to the Persons in whose names the applicable Notes are registered in the Security Register applicable to the Notes at the close of business on the immediately preceding March 1 or September 1, respectively, prior to the applicable Interest Payment Date regardless of whether such day is a Business Day (each, a “Regular Record Date”). Interest on the Notes shall be computed on the basis of a 360-day year consisting of twelve 30-day months. Interest on the Notes shall accrue from and including August 15, 2024. If an Interest Payment Date, the Maturity Date or any earlier Redemption Date with respect to the Notes falls on a day that is not a Business Day, the related payment will be made on the next Business Day as if it were made on the date the payment was due, and no interest will accrue on the amount so payable for the period from and after that Interest Payment Date, the Maturity Date or any such earlier Redemption Date, as the case may be, to the date the payment is made. Interest payments will include accrued interest from and including the date of original issuance or from and including the last date in respect to which interest has been paid, as the case may be, to, but excluding, the Interest Payment Date or the Maturity Date, as the case may be.

(d) Registration and Form. The Notes shall be issuable as Registered Securities as provided in Section 2.02 of this Article II. The Notes shall be issued and may be transferred only in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. All payments of principal, redemption price and accrued unpaid interest in respect of the Notes shall be made by the Company in immediately available funds.

6

(e) Defeasance and Covenant Defeasance. The provisions for defeasance in Section 1302 of the Original Indenture, and the provisions for covenant defeasance in Section 1303 of the Original Indenture, shall be applicable to the Notes.

(f) Further Issues. Notwithstanding anything to the contrary contained in this Tenth Supplemental Indenture or the Original Indenture (but subject to the terms of this Section 2.03(f)), the Company may, from time to time, without the consent of or notice to the Holders, create and issue further securities having the same ranking and terms and conditions as the Notes in all respects, except for the issue date and, in some cases, the public offering price and the first interest payment date. Additional Notes issued in this manner shall be consolidated with and shall form a single series with the previously issued Notes; provided that if such additional Notes are not fungible with the previously issued Notes for U.S. federal income tax purposes, such additional Notes will have a separate CUSIP number. Notice of any issuance of additional Notes shall be given to the Trustee and a new supplemental indenture shall be executed in connection therewith. No such additional Notes may be issued if an Event of Default has occurred and is continuing with respect to the Notes.

(g) Other Terms and Conditions. The Notes shall have such other terms and conditions as provided in the form thereof attached as Exhibit A.

SECTION 2.04. Ranking. The Notes shall be general unsecured obligations of the Company. The Notes shall rank pari passu in right of payment with all unsecured and unsubordinated indebtedness of the Company and senior in right of payment to all subordinated indebtedness of the Company.

REDEMPTION

SECTION 3.01. Optional Redemption.

(a) 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 20 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 either case, accrued and unpaid interest thereon to the Redemption Date.

7

(b) On or after the Par Call Date, the Company may redeem the Notes, 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 being redeemed plus accrued and unpaid interest thereon to the Redemption Date.

SECTION 3.02. General.

(a) Notwithstanding Section 3.01, installments of interest on the Notes that are due and payable on any Interest Payment Date falling on or prior to a Redemption Date will be payable on such Interest Payment Date to the registered Holders of the Notes as of the close of business on the relevant Regular Record Date according to the terms of the Notes and the Indenture. Unless the Company defaults in payment of the redemption price, on and after the Redemption Date, interest will cease to accrue on any Notes or portions thereof that are called for redemption.

(b) Notices of any optional redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with DTC (or another Depository’s) procedures) at least 10 days but not more than 60 days before the Redemption Date to each Holder of the Notes to be redeemed at its registered address. The Company will also provide notice of any optional redemption to the Trustee no later than the date such notice is sent to the Holders, which notice shall include the information required by the Original Indenture to be provided to the Holders in connection with the notice described in the immediately preceding sentence. If the Company elects to have the Trustee give the notice, the Company shall notify the Trustee at least 5 days (unless a shorter period is agreed to by the Trustee) prior to the date notice is sent to Holders. The Company will calculate the redemption price as described in the terms of the Notes redeemed and will deliver an Officer’s Certificate to the Trustee setting forth the redemption price no later than two Business Days prior to the Redemption Date (or such later date as the Trustee may agree), and the Trustee will not be responsible for such calculation nor shall the Trustee have any duty to monitor the accuracy of any calculations made by the Company. The actions and determinations of the Company in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

(c) 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 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 Depository), the redemption of the Notes shall be done in accordance with the policies and procedures of the Depository.

(c) The Company will comply with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and regulations thereunder, to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Repurchase Event. To the extent that the provisions of any securities laws or regulations conflict with this Article IV, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Article IV by virtue of such conflict.

(d) On the Change of Control Repurchase Event payment date, the Company will, to the extent lawful:
