The term “Adjusted Treasury Rate” has the meaning ascribed to that term in the Issuer’s Preliminary Prospectus Supplement, dated February 24, 2021.

*A security rating is not a recommendation to buy, sell or hold securities and should be evaluated independently of any other rating. The rating is subject to revision or withdrawal at any time by the assigning rating organization.

**It is expected that delivery of the Notes will be made on or about the Settlement Date specified above, which will be the seventh business day following the date hereof. Under 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 a trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes more than two business days prior to the scheduled settlement date will be required, by virtue of the fact that the Notes are expected to settle in T+7, to specify an alternative settlement arrangement at the time of any such trade to prevent a failed settlement.
