⁽¹⁾ A securities rating is not a recommendation to buy, sell, or hold securities and may be subject to revision or withdrawal at any time.

⁽²⁾ We expect that delivery of the Notes will be made against payment therefor on or about the settlement date specified in this final term sheet, which will be the second business day following the date of pricing of the Notes (this settlement cycle being referred to as "T+2"). Pursuant to Rule 15c6-1 under the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in one business day, unless the parties to that trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes prior to the first business day before settlement will be required, by virtue of the fact that the Notes initially will settle in T+2, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement and should consult their own advisor.
