Risk Factors:
      Your investment in the Notes involves certain risks, not all of which are
described in this Pricing Supplement. In the consultation with your own
financial and legal advisers, you should carefully consider, among other
matters, the following discussion of risks (and discussion of risk contained in
the Prospectus) before deciding whether an investment in the Notes is suitable
for you. The Notes are not an appropriate investment for you if you are
unsophisticated with respect to their significant components and
interrelationships.

Structure of Notes Indexed to Interest Rates:
         Because the Notes are indexed to the Treasury Rate, there will be
significant risks not associated with a conventional fixed rate debt security.
These risks include fluctuation of the interest rates and the possibility that
you will receive a lower amount of interest. We have no control over a number of
matters, including economic, financial and political events, that are important
in determining the existence, magnitude and longevity of these risks and their
results. In recent years, values of certain interest rates have been volatile,
and volatility in those and other interest rates may be expected in the future.
However, past experience is not necessarily indicative of what may occur in the
future.

Your Return Will be Limited:
         You should understand that because the Notes are subject to a Maximum
Interest Rate, as defined above, the rate of interest that will accrue on the
Notes during any Interest Reset Period will never exceed 8.15% per annum.
