Historical Levels of 6-Month LIBOR

The following table, showing the historical level of 6m USD LIBORREF in effect on the Original Trade Date and for the hypothetical Interest Payment Dates listed below; the Interest Rate payable on any Interest Payment Date for the notes, however, will be determined based on 6m USD LIBORREF in effect on each day during the related Interest Period.  The historical experience of 6m USD LIBORREF should not be taken as an indication of the future performance of 6m USD LIBORREF during the term of the notes. Fluctuations in the level of 6m USD LIBORREF make the notes’ effective Interest Rate difficult to predict and can result in an effective Interest Rate 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.
