It is expected that delivery of the notes will be made against payment therefore on or about September 15, 2021, which is the sixth business day following the date hereof (such settlement cycle being referred to as “T+6”). Under Rule 15c6-1 under 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 prior to the second business day before the delivery of the notes will be required, by virtue of the fact that the notes initially will settle in T+6, to specify an alternative settlement cycle at the time of any such trade to prevent failed settlement. Purchasers of the notes who wish to trade the notes prior to the second business day before the delivery of the notes should consult their own advisors.
