 Depository Trust Company for the accounts of its participants
against payment in New York, New York on or about October 2, 2025, which will be the second business day following the initial trade
date for the notes (this settlement cycle being referred to as “T+2”). Under Rule 15c6-1 under the Securities Exchange Act
of 1934, as amended (the “Exchange Act”), trades in the secondary market generally are required to settle in one business
day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes prior to the business
day preceding the settlement date will be required, by virtue of the fact that the notes initially will settle T+2, to specify an alternate
settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the notes who wish to trade the notes prior
to the business day preceding the settlement date should consult their own advisors.
