The Depositary Shares are not deposits or other obligations of a bank and are not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency.

*   The security ratings above are not a recommendation to buy, sell or hold the Securities. The ratings may be subject to revision or withdrawal at any time by Moody’s, S&P Global Ratings and Fitch. Each of the security ratings above should be evaluated independently of any other security rating.

**   Under Rule 15c6-1 of 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 the trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Depositary Shares on the date of pricing or the next two succeeding business days will be required, by virtue of the fact that the Depositary Shares initially will settle in T+5, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement and should consult their own advisors.
