Pricing Term Sheets

We expect that delivery of the notes will be made against payment thereof on or about the settlement date specified in this communication, which will be the fourth business day following the date of pricing of the notes (this settlement cycle being referred to as “T+4”). Under Rule 15c6-1 of the U.S. Securities and Exchange Commission (the “SEC”) under the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes on the date of pricing or the next succeeding business day will be required, by virtue of the fact that the notes initially will settle in T+4, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of notes who wish to trade notes on the date of pricing should consult their own advisor.
