You should read this Amendment, together with the documents listed below, which together contain the terms of the notes and supersede all prior or contemporaneous oral statements as well as any other written materials. You should carefully consider, among other things, the matters set forth in the “Additional Risk Factors” section beginning on page PRS-7 of the Pricing Supplement and the “Risk Factors” sections beginning on page S-1 of the Prospectus Supplement and page 1 of the Prospectus, as the notes involve risks not associated with conventional debt securities.
