Key Terms

Reference Index (or Index):	CS/RT Emerging Infrastructure Index powered by HOLT
Issuer:	Credit Suisse, acting through its Nassau Branch.
CUSIP:	22546EAE4
AMEX Ticker:	EIW.A
Trade Date:	October 30, 2007
Initial Index Level:	Closing level of the Index on the index business day immediately
	following the Trade Date.
Final Index Level:	Closing level of Index on the Valuation Date.
Valuation Date:	October 30, 2012
Maturity Date:	November 6, 2012
Cap:	Uncapped
Upside Participation:	120%
Downside Participation:	One-for-one exposure on the downside
Redemption Amount at Maturity:	At maturity, the investor will receive an amount in cash equal to the principal amount of the ARES® multiplied by the sum of 1 plus the Index Return. How the Index Return is calculated depends on whether the Final Index Level is greater than, less than or equal to the Initial Index Level.
	a)If the Final Index Level is greater than the Initial Index Level, the Index Return at maturity is:
	Upside Participation * [ (Final Index Level – Initial Index Level) ]
		Initial Index Level
	Thus, if the Final Index Level is greater than the Initial Index Level, the Index Return will be a positive number and the redemption amount will be greater than the principal amount of the securities.
	b)If the Final Index Level is equal to the Initial Index Level, the Index Return at maturity is:
	Zero, and the redemption amount will equal the principal amount of the securities.
	c)If the Final Index Level is less than the Initial Index Level, then the Index Return at maturity is:
	(Final Index Level – Initial Index Level)
	Initial Index Level
	Thus, if the Final Index Level is less than the Initial Index Level, then the Index Return will be negative, and the redemption amount will be less than the principal amount of the securities, and you could lose up to 100% of the value of your investment in the securities.

Historical Performance

CS/RT Emerging Infrastructure Index Powered by HOLT*

We obtained the historical levels of the index from Bloomberg Financial Markets, without independent verification. You should not take the historical levels of the index as an indication of future performance of the index or securities. Because the reference index was launched on September 25, 2007, the calculation agent has retrospectively calculated the levels of the reference index on all dates prior to September 25, 2007 using the same methodology as described in the pricing supplement. All prospective investors should be aware that no actual investment tracking performance of the reference index was possible at any time prior to September 25, 2007.

*The base level of this index is 100.00 taken on November 14, 2002.

•The ARES^® do not pay interest.  Credit Suisse 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 our debt securities.

•An investment in the ARES^® is not the same as an investment in the stocks underlying the index.  An investment in the securities does not entitle you to any ownership interest or other rights in the stocks underlying the index.

•There may be little or no secondary market for the ARES^®. Although application has been made to list the securities on the American Stock 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 value 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 Credit Suisse Securities (USA) LLC may be willing to purchase or sell the ARES in the secondary market, including:

•The current level of the index.

•The prices of stocks comprising the index.

•Interest and yield rates in the market.

•Economic, financial, political and regulatory or judicial events that affect the stocks comprising the index or stock markets generally and that may affect the appreciation of the index.

•Changes in the volatility of the index.

•The time remaining to maturity of the ARES^®.

•The dividend rate on the stocks comprising 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.

•There may be potential conflicts of interest. We and our affiliates play a variety of roles in connection with the securities, including acting as underwriter, index creator, and calculation agent and hedging our obligations under the securities. In performing these duties, the economic interests of the calculation agent and other affiliates are potentially adverse to your interests as a security holder.
