reasonably have been selected or that could apply in connection with the
preparation of these materials or an assessment of the transaction described

market factors and other considerations, could result in different
contemporaneous good faith analyses or assessment of the transaction described
above. Past performance should not be taken as an indication or guarantee of
future performance, and no representation or warranty, express or implied is

involve a high degree of risk and are intended for sale only to sophisticated
investors who are capable of understanding and assuming the risks involved. The
market value of any structured security may be affected by changes in economic,
financial and political factors (including, but not limited to, spot and forward
interest and exchange rates), time to maturity, market conditions and volatility
and the credit quality of any issuer or reference issuer. Any investor
interested in purchasing a structured product should conduct its own
investigation and analysis of the product and consult with its own professional
advisers as to the risks involved in making such a purchase.

for your use only and does not constitute an offer or commitment, a solicitation
of an offer or commitment, or any advice or recommendation, to enter into or

This material has been prepared by CSFB based on assumptions and parameters
determined by it in good faith. It is important that you (recipient) understand
that those assumptions and parameters are not the only ones that might
reasonably have been selected or that could apply in connection with the
preparation of these materials or an assessment of the transaction described
above. A variety of other or additional assumptions or parameters, or other
market factors and other considerations, could result in different
contemporaneous good faith analyses or assessment of the transaction described
above. Past performance should not be taken as an indication or guarantee of
future performance, and no representation or warranty, express or implied is
made regarding future performance. Opinions and estimates may be changed without
notice. The information set forth above has been obtained from or based upon
sources believed by CSFB to be reliable, but CSFB does not represent or warrant

involve a high degree of risk and are intended for sale only to sophisticated
investors who are capable of understanding and assuming the risks involved. The
market value of any structured security may be affected by changes in economic,
financial and political factors (including, but not limited to, spot and forward
interest and exchange rates), time to maturity, market conditions and volatility
and the credit quality of any issuer or reference issuer. Any investor
interested in purchasing a structured product should conduct its own
investigation and analysis of the product and consult with its own professional
advisers as to the risks involved in making such a purchase.
