**Settlement and Sale of the Notes

The Issuer expects to deliver the Notes against payment for the Notes on or about May 7, 2026, which will be the fifth business day following April 30, 2026, the date of the pricing of the Notes. Since trades in the secondary market generally settle in one business day, purchasers who wish to trade Notes on any date prior to the business day before delivery will be required, by virtue of the fact that the Notes initially will settle in T+5, to specify alternative settlement arrangements to prevent a failed settlement.
