Certain Product Risks

· Your investment may result in a loss of up to 100% of the principal amount of securities you hold. If a Knock-In Event has occurred and the Final Level of the Lowest Performing Underlying is less than its Initial Level, you will be fully exposed to any depreciation in the Lowest Performing Underlying. Regardless of the amount of any payment you receive on the securities, your actual yield may be different in real value terms.

· The securities do not provide for regular fixed interest payments. If a Coupon Barrier Event has occurred on an Observation Date, you will not receive the contingent coupon for such Observation Date on the immediately following Contingent Coupon Payment Date or on any subsequent Contingent Coupon Payment Date.

· More favorable terms to you are generally associated with an Underlying with greater expected volatility and therefore can indicate a greater risk of loss. You should therefore understand that a relatively higher contingent coupon may indicate an increased risk of loss.

· At maturity or upon Automatic Redemption, the securities will not pay more than the principal amount of securities you hold plus the final contingent coupon, if any.

· The value of the securities and the payment of any amount due on the securities are subject to the credit risk of Credit Suisse.

· The securities are subject to Automatic Redemption, which exposes you to reinvestment risk and may limit your ability to be paid contingent coupons over the full term of the securities.
