\* These securities ratings have been provided by S&P, Moody's and Fitch, respectively. None of these ratings is a recommendation to buy, sell or hold these securities. Each rating may be subject to revision or withdrawal at any time, and should be evaluated independently of any other rating.

\*\* It is expected that delivery of the notes will be made against payment thereof on or about March 7, 2023, which will be the third business day following the date of the pricing of the notes (such settlement being referred to as "T+3"). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market are generally required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes prior to the second business day before the settlement date will be required, by virtue of the fact that the notes will initially settle in T+3, to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement.
