Risk Factors

An investment in the notes entails certain risks not associated with an investment in conventional floating rate or fixed rate medium-term notes.  See “Risk Factors” in the Series I MTN prospectus supplement.

Historical Levels of the 30yr CMS Rate and 10yr CMS Rate

The following shows the 30yr CMS Rate and the 10yr CMS Rate in effect on the Trade Date and on the hypothetical Interest Reset Dates listed below. The historical experience of the 30yr CMS Rate and 10yr CMS Rate should not be taken as an indication of the future performance of the 30yr CMS Rate and 10yr CMS Rate during the term of the Notes.  Fluctuations in the level of the 30yr CMS Rate and 10yr CMS Rate make the Notes’ effective interest rate after August 29, 2008, difficult to predict and can result in effective interest rates to investors that are lower than anticipated. In addition, historical interest rates are not necessarily indicative of future interest rates. Fluctuations in interest rates and interest rate trends that have occurred in the past are not necessarily indicative of fluctuations that may occur in the future, which may be wider or narrower than those that have occurred historically.
