	Delivery of the notes is expected to be made against payment for the notes on June 22, 2022, which will be the tenth business day following the date hereof (this settlement cycle being referred to as “T+10”). Under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes on any date prior to the second business day before delivery will be required, by virtue of the fact that the notes initially will settle in T+10, to specify alternate settlement arrangements at the time of any such trade to prevent a failed settlement. Purchasers of the notes who wish to trade the notes on any date prior to the second business day before delivery should consult their own advisers.
