It is expected that delivery of the notes will be made against payment therefor on or about January 30, 2024, which is the third business day following the date hereof (such settlement cycle being referred to as “T+3”). Pursuant to Rule 15c6-1 under the Exchange Act, 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 prior to the settlement date will be required, by virtue of the fact that the notes initially will settle in T+3, 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 such notes prior to the second business day prior to the settlement date should consult their own advisors.
