 of New York Mellon will initially act as calculation agent.

We will pay interest on the floating rate notes quarterly in arrears on January 1, April 1, July 1 and October 1 (we refer to each such date as a floating rate interest payment date) of each year, subject in each case to the business day convention set forth below, beginning on October 1, 2025, until the floating rate notes shall have been paid in full. If any floating rate interest payment date would fall on a day that is not a business day, other than the floating rate interest payment date that is also the date of maturity for the floating rate notes, that floating rate interest payment date will be postponed to the following day that is a business day, except if such next business day is in a different month, in which case such floating rate interest payment date will be the immediately preceding day that is a business day. If the date of maturity of the floating rate notes is not a business day, payment of principal and interest on the floating rate notes will be made on the following day that is a business day and no interest will accrue for the period from and after such date of maturity of the floating rate notes. Interest on a floating rate note will be paid to the person in whose name that floating rate note was registered at the close of business on the December 17, March 17, June 16 or September 16, as the case may be, whether or not a business day, prior to the applicable floating rate interest payment date, except in the case of the floating rate interest payment date that is also the date of maturity of the floating rate notes.

Except as described below for the first floating rate interest period, on each floating rate interest payment date, we will pay interest for the period commencing on and including the immediately preceding floating rate interest payment date and ending on and including the day preceding the next floating rate interest payment date. We refer to this period as a floating rate interest period. The first floating rate interest period will begin on and include July 1, 2025 and will end on and include the day preceding the first floating rate interest payment date.
