* Pursuant to 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 notes in the secondary market prior to the date that is two business days before the settlement date will be required, by virtue of the fact that the notes initially will settle T+3 (on March 6, 2023) to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of notes who wish to trade notes prior to the date that is two business days before the settlement date should consult their own advisors.
