Who Should Invest in the ARES^®:

Investors who are interested in doubling the upside participation in the Reference Index, subject to a cap, and are able to withstand a loss of their investment in the event the Reference Index declines.

Hypothetical Upside Scenario:

• The Reference Index appreciated by the valuation date: Investors receive back their initial investment plus 200% of the appreciation of the Reference Index, subject to a cap.

Hypothetical Downside Scenario:

• The Reference Index depreciated by the valuation date: Investors participate in 100% of the losses; if the Reference Index declines to 0.00, investors will lose 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 preliminary pricing supplement subject to completion dated December 5, 2007, the product supplement dated December 5, 2007, the prospectus supplement dated May 7, 2007 and the prospectus dated March 29, 2007 before investing in the securities.

An investment in ARES^®are not principal protected. You may receive less at maturity than you originally invested, or you may receive nothing should the Reference Index decline to zero.

The ARES do not pay interest. CSSU will not pay interest on the ARES. Even if the payment at maturity exceeds the principal amount of the ARES, you may receive less at maturity than you could have earned on ordinary interest-bearing debt securities with similar maturities, including other of CSSU debt securities.

The ARES may pay less than the full appreciation of the Reference Index at maturity. If the Reference Index appreciates, your return will be based on two times the percentage increase of the Reference Index, subject to a cap, provided, however, that the index return will not be greater than 200%.

An investment in ARES is not the same as an investment in the stocks underlying the Reference Index or a security directly linked to such Index. The payment of dividends on the stocks which comprise, or underlie, a Reference Index has no effect on the calculation of the value of that Reference Index. Accordingly, the Index Return based on the percentage change in the Reference Index is not the same as the total return based on the purchase of those underlying stocks held for a similar period. In addition, you may lose part of your investment even if the Reference Index has risen at certain times during the term of the securities before falling to a level below the initial index level on the date or dates on which the final index level is calculated.

The U.S. federal income tax consequences of the securities are uncertain. No ruling is being requested from the Internal revenue Service, or the IRS, with respect to the securities and we cannot assure you that the IRS or any court will agree with the tax treatment described under “Certain United States Federal Income Tax Considerations” in the product and pricing supplements.

There may be little or no secondary market for the ARES. The ARES will not be listed on any securities exchange. We cannot assure you that a secondary market for the ARES will develop. CSSU currently intends to make a market in the ARES, 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 ARES may be influenced by many unpredictable factors. Many factors, most of which are beyond our control, will influence the value of the ARES and the price at which CSSU may be willing to purchase or sell the ARES in the secondary market, including:

• The current level of the Reference Index. • Whether the level of the Reference Index has exceeded the cap or has declined below the initial index level. • Interest and yield rates in the market. • The volatility of the Reference Index. • Economic, financial, political and regulatory or judicial events that affect the securities underlying the Reference Indices or stock markets generally and which may affect the appreciation of the Reference Index. • The time remaining to the maturity of the ARES. • The dividend rate on the stocks underlying the Reference 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.
