(ii) in the case of Legal Defeasance, the Company must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee or an Internal Revenue Service ruling, in either case to the effect that the Holders of the Notes and beneficial owners thereof will not recognize income, gain or loss for United States federal income tax purposes as a result of such Legal Defeasance, and will be subject to United States federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

(iv) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit) or insofar as Events of Default from bankruptcy or insolvency events are concerned, at any time in the period ending on the 91st day after the date of deposit;

(v) the Company must deliver to the Trustee an Officer’s Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders of the Notes over other creditors of the Company, or with the intent of defeating, hindering, delaying or defrauding creditors of the Company or others; and

The terms of other series of Securities issued under the Base Indenture may vary with respect to interest rates, issue dates, maturity, redemption, repayment, currency of payment and otherwise as provided in the Base Indenture. The Base Indenture further provides that securities of a single series may be issued at various times, with different maturity dates and may bear interest at different rates. This series of Securities is limited in aggregate initial principal amount as specified in the Supplemental Indenture.

Each Installment Payment shall constitute a payment of interest (at a rate of 5.93% per annum) and a partial repayment of principal on the Notes, allocated with respect to each Note as set forth in the schedule below:

However, a Holder shall have the right to require the Company to repurchase some or all of its Notes for cash at the Repurchase Price per Note and on the Repurchase Date, upon the occurrence of certain events and subject to the conditions set forth in the Indenture.

This Note is not entitled to the benefit of any sinking fund. The Indenture contains provisions for satisfaction and discharge, legal defeasance and covenant defeasance of this Note upon compliance by the Company with certain conditions set forth therein, which provisions apply to this Note.

If an Event of Default with respect to the Notes shall occur and be continuing, then (unless no declaration of acceleration or notice is required for such Event of Default) either the Trustee or the Holders of not less than 25% in aggregate principal amount of the Notes then outstanding may declare the aggregate principal amount of the Notes, and all interest accrued thereon, to be due and payable immediately, in the manner, subject to the conditions and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the Company and the Trustee, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding, to execute supplemental indentures for certain purposes as described therein.

No provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the Repurchase Price, if applicable, of and all Installment Payments on this Note at the time, place and rate, and in the coin or currency, herein and in the Indenture prescribed.

The Notes are originally being issued as part of the 5.750% Tangible Equity Units (the “Units”) issued by the Company pursuant to that certain Purchase Contract Agreement, dated as of February 5, 2026, between the Company and U.S. Bank Trust Company, National Association, as Purchase Contract Agent, as Trustee and as attorney-in-fact for the holders of Purchase Contracts from time to time (the “Purchase Contract Agreement”). Holders of the Units have the right to separate such Units into their constituent parts, consisting of Separate Purchase Contracts (as defined in the Purchase Contract Agreement) and Separate Notes, during the times, and under the circumstances, described in the Purchase Contract Agreement. Following separation of any Unit into its constituent Separate Note and Separate Purchase Contract, the Separate Notes are transferable independently from the Separate Purchase Contracts. In addition, Separate Notes can be recombined with Separate Purchase Contracts to recreate Units, as provided for in the Purchase Contract Agreement. Reference is hereby made to the Purchase Contract Agreement for a more complete description of the terms thereof applicable to the Units.

The Company, the Trustee and any agent of the Company or the Trustee may deem and treat the Person in whose name this Note shall be registered upon the Security register for such series as the absolute owner of such Note (whether or not such Note shall be overdue and notwithstanding any notation of ownership or other writing thereon) for the purpose of receiving payment of or on account of the principal of and, subject to the provisions of the Indenture, interest on such Note and for all other purposes; and neither the Company nor the Trustee nor any agent of the Company or the Trustee shall be affected by any notice to the contrary.

The Notes are initially issued in registered, global form without coupons in denominations equal to $7.8225 initial principal amount and integral multiples in excess thereof.

No service charge shall be made to any holder for any registration of, transfer or exchange of the Notes, but the Company or the Trustee may require payment by the holder of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in connection with any registration of transfer or exchange of the Notes.
