Product Snapshot

Who Should Invest in the CertPLUS Securities:

· Investors who are bullish on the Index and looking to add exposure to the S&P 500^® Index in their portfolio and who are interested in uncapped upside participation in the Index, and are able to withstand a loss of their investment in the event the Index declines by 40% or more.

Hypothetical Upside Scenario:

· The Index appreciated by the valuation date:  Investors receive back their initial investment plus [100%- 110%] of the appreciation of the Index.

Hypothetical Downside Scenario:

· The Index depreciated by the valuation date and the Index depreciated by 40% or more at any time during the life of the investment resulting in a Trigger Event:  Investors participate in 100% of the losses and can lose up to their entire investment.

*Hypothetical scenarios are neither indicators nor guarantees of future Index performance.  Actual results will vary, perhaps materially from the hypothetical analysis.

Investment Considerations

A purchase of the securities involves risks.  This section summarizes certain additional risks relating to the securities.  We urge you to read the following information about these risks, together with the information in the pricing supplement subject to completion dated April 29, 2008, the prospectus supplement dated March 24, 2008 and the prospectus dated March 29, 2007 before investing in the securities.

An investment in the Securities is not principal protected.  You may receive less at maturity than you originally invested, or you may receive nothing should the Index decline to zero.

The securities do not pay interest.  Credit Suisse Securities (USA) LLC will not pay interest on the Securities.  Even if the payment at maturity exceeds the principal amount of the Securities,  you may receive less at maturity than you could have earned on ordinary interest-bearing debt securities with similar maturities, including other of our debt securities.

An investment in the Securities is not the same as an investment in the stocks underlying the Index.  The payment of dividends on the stocks which underlie the Index has no effect on the calculation of the level of that Index.  Therefore, the return on your investment based on the percentage change in the Index is not the same as the total return based on the purchase of those underlying stocks.

There may be little or no secondary market for the Securities.  The Securities will not be listed on any securities exchange.  We cannot assure you that a secondary market for the Securities will develop.  Credit Suisse Securities (USA) LLC currently intends to make a market in the Securities, although it is not required to do so and may stop making a market at any time.  If you have to sell your securities prior to maturity, you may have to sell them at a substantial loss.

The market price of the Securities may be influenced by many unpredictable factors. Many factors, most of which are beyond our control, will influence the value of the Securities and the price at which Credit Suisse Securities (USA) LLC may be willing to purchase or sell the Securities in the secondary market, including:

·   The level of the Index.   ·   Interest and yield rates in the market.   ·   The volatility of the Index.   ·   Economic, financial, political and regulatory or judicial events that affect the securities underlying the reference index or stock markets generally and which may affect the appreciation of the Index.   ·   The time remaining to the maturity of the Securities.   ·   The dividend rate on the stocks underlying the Index.   ·   Credit Suisse’s creditworthiness.

Some or all of these factors may influence the price that you will receive if you choose to sell your securities prior to maturity.  The impact of any of the factors set forth above may enhance or offset some or all of any change resulting from another factor or factors.
