* Note: A securities rating is not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time.

** We expect that delivery of the Bonds will be made against payment for the Bonds on the Settlement Date, which will be the sixth business day following the date of this final term sheet (this settlement cycle being referred to as “T+6”). Under Rule 15c6-1 of the SEC under the Exchange Act, trades in the secondary market generally are required to settle in two business days unless the parties to that trade expressly agree otherwise. Accordingly, purchasers who wish to trade Bonds on the date of this final term sheet or the next succeeding three business days will be required, by virtue of the fact that the Bonds initially will settle in T+6, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement and should consult their own advisors.
