(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. An explanation of the significance of ratings may be obtained from the ratings agencies. Generally, ratings agencies base their ratings on such material and information, and such of their own investigations, studies and assumptions, as they deem appropriate. Each of the security ratings above should be evaluated independently of any other security rating.

(2) 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 the notes prior to the first business day before the delivery of the notes 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 those notes prior to their date of delivery should consult their own advisors.
