** Note: The Issuer expects to deliver the Notes against payment for the Notes on the third business day following the Trade Date (“T+3”). Under Rule 15c6-1 of the Exchange Act, trades in the secondary market generally are required to settle in one business day, unless the parties to a trade expressly agree otherwise. Accordingly, purchasers who wish to trade Notes on the date hereof or the next succeeding business day will be required, by virtue of the fact that the Notes initially will settle in T+3, to specify alternative settlement arrangements to prevent a failed settlement. Purchasers of the Notes who wish to trade the Notes during the period described above should consult their own advisors.
