\* It is expected that delivery of the Notes will be made against payment for the Notes on or about May 12, 2026, which will be the fifth business day following the date hereof (this settlement cycle being referred to as T+5). Under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in one business day, unless the parties to a trade expressly agree otherwise. Accordingly, purchasers who wish to trade Notes prior to one business day before the settlement date 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. 

\*\* Note: A securities rating is not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time.
