The Issuer expects to deliver the Notes on or about October 30, 2008. Under Rule 15c6-1 of the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle within three business days, unless the parties to any such trade expressly agree otherwise. Accordingly, if an investor wishes to trade the Notes on any day prior to the third business day before the date of delivery of the Notes, the investor and its counterparty will be required, by virtue of the fact that the Notes initially will settle on a delayed basis, to agree to a delayed settlement cycle at the time of any such trade to prevent a failed settlement.

 

                On October 28, 2008, the Issuer filed with the Securities and Exchange Commission a Current Report on Form 8-K containing certain financial and related information for the quarter ended September 30, 2008.  The information contained in that Current Report is expressly incorporated by reference into this Pricing Supplement and the related Prospectus and Prospectus Supplement.  Investors should read this and other information which has been incorporated into this offering document.  (See “Where You Can Find Additional Information” in the accompanying Prospectus.)
