** It is expected that delivery of the notes will be made, against payment for the notes, on or about May 18, 2023, which will be the third business day following the pricing of the notes. Under 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 a trade expressly agree otherwise. Accordingly, purchasers of the notes who wish to trade the notes on the date of this term sheet will be required, because the notes initially will settle within three business days (T+3), 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 on the date of this term sheet should consult their own legal advisors.
