To the extent it is lawful, the Company promises to pay interest on any interest payment due on such principal amount but unpaid at a rate of 5.600% per annum compounded semi-annually.

The Company will pay interest semi-annually in arrears on March 15 and September 15 of each year (each, an “Interest Payment Date”), commencing March 15, 2024. Interest on the Securities will accrue from the most recent date to which interest has been paid or, if no interest has been paid on the Securities, from the date of the original issuance. Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months.

2. Method of Payment.

The Company shall pay interest on the Securities (except defaulted interest) to the persons who are the registered Holders at the close of business on the Record Date on the next preceding Interest Payment Date. Holders must surrender Securities to a Paying Agent to collect principal payments. Principal of, premium, if any, and interest on the Securities will be payable in United States Dollars at the office or agency of the Company maintained for such purpose, in the contiguous United States or at the option of the Company, payment of interest may be made by check mailed to the Holders of the Securities at the addresses set forth upon the registry books of the Company; provided, however, Holders of Global Notes will be entitled to receive interest payments (other than at maturity) by wire transfer of immediately available funds, if appropriate wire transfer instructions have been received in writing by the Trustee not fewer than 15 days prior to the applicable Interest Payment Date. Such wire instructions, upon receipt by the Trustee, shall remain in effect until revoked by such Holder. No service charge will be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.11, 3.6 and 9.6 of the Indenture).

(i) 100% of the principal amount of the Securities to be redeemed; and

(ii) (a) the sum of the present values of the remaining scheduled payments of principal and interest on the Securities to be redeemed, in each case discounted to the redemption date (assuming the Securities of such series matured on the applicable 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 thereon to the date of redemption,

Holders of the Securities may not enforce the Indenture or the Securities, except as provided in the Indenture. The Trustee may require indemnity or security satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Securities may direct the Trustee in its exercise of any trust or power with respect to such Securities.
