ARTICLE II

General Terms and Conditions of the Notes

SECTION 2.01. Designation and Principal Amount. There is hereby authorized and established a series of Securities under the Indenture, designated as the “5.850% Senior Notes due 2029,” unlimited in aggregate principal amount. The aggregate principal amount of the Notes to be initially issued shall be $400,000,000. Additional Notes may be issued pursuant to Section 2.02 hereof.

SECTION 2.02. Further Issues. So long as no Default or Event of Default shall have occurred and be continuing with respect to the Notes at the time of such issuance, the Company may from time to time, without the consent of the Holders of the Notes, issue additional Notes. Any such additional Notes will have the same interest rate, maturity date and other terms as the Notes, except for the issue date, issue price and initial Interest Payment Date. Any such additional Notes, together with any other Notes previously issued pursuant to this Supplemental Indenture, will constitute a single series of Securities under the Indenture; provided, however, that if any such additional Notes would not be fungible with the outstanding Notes for U.S. federal income tax purposes, the Company shall cause such additional Notes to be issued with a separate CUSIP number.

SECTION 2.03. Maturity. The Notes will mature on March 18, 2029.

SECTION 2.04. Interest. The Notes will bear interest (computed on the basis of a 360-day year consisting of twelve 30-day months) from March 18, 2024 at the rate of 5.850% per annum, payable semi-annually in arrears. Interest payable on each Interest Payment Date will include interest accrued from March 18, 2024, or from the most recent Interest Payment Date to which interest has been paid or duly provided for. The Interest Payment Dates on which such interest shall be payable are March 18 and September 18, commencing on September 18, 2024; and the Regular Record Date for the interest payable on any Interest Payment Date is the close of business on March 1 or September 1, as the case may be, immediately preceding the relevant Interest Payment Date, whether or not that day is a Business Day.

SECTION 2.05. Method and Place of Payment. Payment of the principal of (and premium, if any) and interest on the Notes will be made at the Corporate Trust Office of the Trustee, or an office or agency maintained by the Company for such purpose, in the continental United States, in United States dollars; provided, however, that at the option of the Company payment of interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register; and provided further, however, that all payments in respect of Global Securities shall be made by wire transfer in same-day funds in accordance with the applicable procedures of the Depositary. In any case where the date of maturity of interest on, premium, if any, or principal of any Note, the date fixed for redemption of the Notes or any Change of Control Payment Date is not a Business Day, then the relevant payment need not be made on such date but may be made on the next succeeding Business Day with the same force and effect as if made on such date and no interest shall accrue in respect of such amount for the period from and after such date. The Notes may be presented for registration of transfer and for exchange, and notices to or upon the Company in respect of such Notes may be served, at the Corporate Trust Office of the Trustee, or an office or agency maintained by the Company for such purpose, in the continental United States.

SECTION 2.06. Optional Redemption. Prior to the Par Call Date (as defined below), 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:

(a) (i) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed discounted to the redemption date (assuming such 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 (as defined below), plus 25 basis points, less (ii) interest accrued to the date of redemption, and

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

plus, in each case, any accrued and unpaid interest on the Notes to be redeemed to, but not including, the date of redemption.

On or after the Par Call Date, the Company may, at its option, 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 to be redeemed, plus accrued and unpaid interest on the Notes to be redeemed to, but not including, the date of redemption.

The following terms are relevant to the determination of the redemption price of the Notes.

“Business Day” means mean each Monday, Tuesday, Wednesday, Thursday and Friday which is not a day on which the Trustee or banking institutions in the Borough of Manhattan, The City and State of New York are obligated or authorized by law to close.

“Par Call Date” means February 18, 2029 (the date that is one month prior to the maturity of the Notes).

“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). In determining the Treasury Rate, the Company shall select, as applicable: (i) 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 (ii) 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 (iii) 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 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. The Trustee shall not be responsible or liable for any determination, calculation, or verification of the redemption price.

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 record of the Notes to be redeemed.

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.

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 2.07. Mandatory Redemption; Offers to Purchase; Open Market Purchases. The Company is not required to make any sinking fund payments or mandatory redemption with respect to the Notes. Notwithstanding any provision hereunder or in the Indenture to the contrary, the Company and its Affiliates may purchase Notes from investors who are willing to sell from time to time, either in the open market at prevailing prices or in private transactions at negotiated prices. Notes that the Company or any of its Affiliates purchase may, at the Company’s discretion, be held, resold or canceled.

SECTION 2.08. Appointment of Agents. The Trustee will initially be the Paying Agent, DTC Custodian, Authenticating Agent and Security Registrar for the Notes.

SECTION 2.09. Global Securities. The Notes will be issued in the form of one or more permanent Global Securities in definitive, fully registered form, and will be subject to the terms and conditions of Section 2.01, Section 2.02 and Section 2.11 of the Indenture.

SECTION 2.10. Change of Control. (a) Upon the occurrence of a Change of Control Triggering Event, unless the Company has exercised its option to redeem the Notes pursuant to Section 2.06, each Holder of the Notes will have the right to require the Company to purchase all or a portion of such Holder’s Notes pursuant to an offer made in accordance with the terms of this Section 2.10 (the “Change of Control Offer”) at a purchase price equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but not including, the date of purchase, subject to the rights of Holders of the Notes on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date.

(b) Within 30 days following any Change of Control Triggering Event, or at the Company’s option, prior to any Change of Control but after public announcement of the pending Change of Control, the Company shall give to each Holder of the Notes, with a copy to the Trustee, a notice governing the terms of the Change of Control Offer that:

(i) describes the transaction or transactions that constitute or may constitute the Change of Control Triggering Event;

(ii) offers to repurchase all Notes tendered;

(iii) sets forth the payment date for the repurchase of the Notes, which date will be at least 30 days but no more than 60 days from the date such notice is given, other than as may be required by law (the “Change of Control Payment Date”);

(iv) if given prior to the date of consummation of the Change of Control, states that the Change of Control Offer is conditioned on the Change of Control Triggering Event occurring on or prior to the Change of Control Payment Date;

(v) discloses that any Note not tendered for repurchase will continue to accrue interest; and

(vi) specifies the procedures for tendering Notes.

(c) Holders of the Notes electing to have Notes purchased pursuant to a Change of Control Offer will be required to: (i) surrender their Notes to the Paying Agent on the address specified in the notice, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Note completed or (ii) transfer their Notes to the Paying Agent by book-entry transfer pursuant to the applicable procedures of the Paying Agent, prior to the close of business on the third Business Day prior to the Change of Control Payment Date.

(d) The Company will not be required to make a Change of Control Offer upon the occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and the third party purchases all Notes properly tendered and not withdrawn under its offer.

(e) 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. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the Notes, the Company will comply with those securities laws and regulations and will not be deemed to have breached its obligations under this Section 2.10 by virtue of any such conflict.

(f) Solely for purposes of this Section 2.10, the following terms shall have the following meanings:

“Change of Control” means the occurrence of any of the following:

(i) the direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the Company’s assets and the assets of its Subsidiaries, taken as a whole, to any “person” (as that term is used in Section 13(d)(3) of the Exchange Act), other than the Company or one of its Subsidiaries;

(ii) the Company becomes aware of (by way of a report or any other filing pursuant to Section 13(d) of the Exchange Act, proxy, vote, written notice or otherwise) the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any “person” (as that term is used in Section 13(d)(3) of the Exchange Act), becomes the ultimate “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), of more than 50% of the Company’s outstanding Voting Stock;

(iii) the Company consolidates with, or merges with or into, any person, or any person consolidates with, or merges with or into, the Company, in any such event pursuant to a transaction in which any of the Company’s outstanding Voting Stock or the Voting Stock of such other person is converted into or exchanged for cash, securities or other property, other than any such transaction where the shares of the Company’s Voting Stock outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of the Voting Stock of the surviving person or any direct or indirect parent company of the surviving person immediately after giving effect to such transaction; or

(iv) the adoption of a plan relating to the Company’s liquidation or dissolution.

“Change of Control Triggering Event” means the Notes cease to be rated Investment Grade by at least two of the three Rating Agencies on any date during the period (the “Trigger Period”) commencing 60 days prior to the first public announcement of the Change of Control or the Company’s intention to effect a Change of Control and ending 60 days following consummation of such Change of Control, which Trigger Period will be extended following consummation of a Change of Control for so long as any of the Rating Agencies has publicly announced that it is considering a possible ratings change. Unless at least two of the three Rating Agencies are providing a rating for the Notes at the commencement of any Trigger Period, the Notes will be deemed to have ceased to be rated Investment Grade by at least two of the three Rating Agencies during that Trigger Period. Notwithstanding the foregoing, no Change of Control Triggering Event will be deemed to have occurred in connection with any particular Change of Control unless and until such Change of Control has actually been consummated.

“Investment Grade” means a rating equal to or higher than Baa3 (or the equivalent) by Moody’s; a rating equal to or higher than BBB- (or the equivalent) by S&P; a rating equal to or higher than BBB- (or the equivalent) by Fitch; and the equivalent investment grade credit rating from any replacement Rating Agency or Rating Agencies selected by the Company.

“Rating Agencies” means:

(i) each of ▇▇▇▇▇’▇ Investors Service, Inc., a subsidiary of ▇▇▇▇▇’▇ Corporation, and its successors (“Moody’s”), ▇▇▇▇▇ Ratings, Inc., and its successors (“Fitch”), and S&P Global Ratings, a division of S&P Global Inc., and its successors (“S&P”); and

(ii) if any of the Rating Agencies ceases to provide rating services to issuers or investors, and no Change of Control Triggering Event has occurred or is occurring, a “nationally recognized statistical rating organization” as defined in Section 3(a)(62) of the Exchange Act that is selected by the Company as a replacement for Moody’s, S&P, Fitch or all of them, as the case may be.

“Voting Stock” means, with respect to any specified person as of any date, the Capital Stock of such person that is at the time entitled to vote generally in the election of the board of directors of such person.

Notwithstanding the foregoing, the requirement of Section 11.02 of the Indenture that no supplemental indenture shall reduce the amount payable upon the redemption of any Note or accelerate the time at which such Note may be redeemable shall not apply to this Section 2.10.

SECTION 2.11. Defeasance. The provisions of Article IV of the Indenture will apply to the Notes. If the Company exercises its Covenant Defeasance option pursuant to Section 4.02 and 4.04 of the Indenture, in addition to the provisions of the Indenture set forth in Section 4.04, the Company also shall be released from its obligations under Section 2.10 of this Supplemental Indenture.

Trustee Not Responsible for Recitals, etc. The recitals contained herein and in the Notes (except in the certificate of authentication) shall be taken as the statements of the Company, and the Trustee assumes no responsibility or liability for the correctness of the same.

EACH OF THE PARTIES HERETO ACKNOWLEDGES AND AGREES THAT IT HAS RECEIVED FULL AND SUFFICIENT CONSIDERATION FOR THIS PROVISION AND THAT THIS PROVISION IS A MATERIAL INDUCEMENT FOR SUCH PARTIES ENTERING INTO THIS SUPPLEMENTAL INDENTURE.

SECTION 4.04. Separability. If any provision in this Supplemental Indenture or the Notes is deemed unenforceable, it shall not affect the validity or enforceability of any other provision set forth herein, or of this Supplemental Indenture or of the Notes as a whole.
