General

•

The securities are designed for investors who are mildly bearish, neutral or mildly bullish on the Underlyings. Investors should be willing to lose some or all of their investment if a Knock-In Event occurs with respect to any Underlying. Any payment on the securities is subject to our ability to pay our obligations as they become due.

•

Interest will be paid quarterly in arrears at a rate per annum that will depend on whether a Knock-In Event occurs. If a Knock-In Event does not occur, interest will be paid at an Applicable Rate per annum that is expected to be 11.25% (approximately 8.4375% over the term of the securities and to be determined on the Trade Date). If a Knock-In Event occurs during any quarterly Observation Period, interest for that quarterly period and each subsequent quarterly interest period will be paid at an Applicable Rate per annum that is expected to be 3.0% (approximately 2.25% over the term of the securities and to be determined on the Trade Date). Interest will be calculated on a 30/360 basis, subject to Early Redemption.

•	The Issuer may redeem the securities, in whole but not in part, on any Interest Payment Date scheduled to occur on or after August 22, 2011. No interest will accrue or be payable following an Early Redemption.

•	Senior unsecured obligations of Credit Suisse AG, acting through its Nassau Branch, maturing February 21, 2012.†

•	Minimum purchase of $1,000. Minimum denominations of $1,000 and integral multiples in excess thereof.

•	The securities are expected to price on or about May 17, 2011 (the “Trade Date”) and are expected to settle on or about May 20, 2011. Delivery of the securities in book-entry form only will be made through The Depository Trust Company.

Key Terms

Issuer:	Credit Suisse AG (“Credit Suisse”), acting through its Nassau Branch
Underlyings:	Each Underlying is identified in the table below, together with its Bloomberg ticker symbol, Initial Level and Knock-In Level:
	Underlying	Ticker	Initial Level	Knock-In Level
	Russell 2000 Index (“RTY”)	RTY
	iShares® MSCI Emerging Markets Index Fund (“EEM”)	EEM UP
	United States Oil Fund, LP (“USO”)	USO

Applicable Rate:	•	If a Knock-In Event does not occur, the Applicable Rate is expected to be 11.25% per annum (approximately 8.4375% over the term of the securities and to be determined on the Trade Date).
	•	If a Knock-In Event occurs during any quarterly Observation Period, the Applicable Rate for the corresponding quarterly interest period and each subsequent quarterly interest period is expected to be 3.0% per annum (approximately 2.25% over the term of the securities and to be determined on the Trade Date).
	Interest will be calculated on a 30/360 basis.
Interest Payment Dates:	Unless redeemed earlier, interest will be paid quarterly in arrears at the Applicable Rate per annum on August 22, 2011, November 21, 2011 and the Maturity Date, subject to the modified following business day convention. No interest will accrue or be payable following an Early Redemption.
Redemption Amount:	The Redemption Amount you will be entitled to receive will depend on the individual performance of each Underlying and whether a Knock-In Event occurs. If the securities are not subject to Early Redemption, the Redemption Amount will be determined as follows:
	•	If a Knock-In Event occurs during any Observation Period, the Redemption Amount will equal the principal amount of the securities you hold multiplied by the sum of one plus the Underlying Return of the Lowest Performing Underlying. In this case, the maximum Redemption Amount will equal the principal amount of the securities. Therefore, unless the Final Level of each of the Underlyings is greater than or equal to its Initial Level, the Redemption Amount will be less than the principal amount of the securities and you could lose your entire investment.
	•	If a Knock-In Event does not occur during any Observation Period, the Redemption Amount will equal the principal amount of the securities you hold.
	Any payment on the securities is subject to our ability to pay our obligations as they become due.
Early Redemption:	The Issuer may redeem the securities in whole, but not in part, on any Interest Payment Date scheduled to occur on or after August 22, 2011, upon at least three business days notice, at 100% of the principal amount of the securities, together with the interest payable on that Interest Payment Date.
Knock-In Event:	A Knock-In Event occurs if the closing level of any Underlying is less than or equal to its Knock-In Level on any trading day for that Underlying during any Observation Period.
Knock-In Level:	The Knock-In Level for each Underlying will be approximately 65% of the Initial Level of such Underlying.
Lowest Performing Underlying:	The Underlying with the lowest Underlying Return.
Underlying Return:	For each Underlying, the Underlying Return will be calculated as follows:

Final Level – Initial Level

Initial Level

, subject to a maximum of zero

Initial Level:*	For each Underlying, the closing level of such Underlying on the Trade Date.
Final Level:	For each Underlying, the closing level of such Underlying on the Valuation Date.
Observation Periods:	There are three quarterly Observation Periods. The first quarterly Observation Period will be from but excluding the Trade Date to and including the first Observation Date. Each subsequent quarterly Observation Period will be from but excluding an Observation Date to and including the next following Observation Date.
Observation Dates:†	August 17, 2011, November 16, 2011 and the Valuation Date.
Valuation Date:†	February 15, 2012
Maturity Date:†	February 21, 2012
Listing:	The securities will not be listed on any securities exchange.
CUSIP:	22546E6Z2

* In the event that the closing level for any Underlying is not available on the Trade Date, the Initial Level for such Underlying will be determined on the immediately following trading day on which a closing level is available.

† The determination of the closing level for each Underlying on each Observation Date, other than the Valuation Date, is subject to postponement if such date is not a trading day for such Underlying or as a result of a market disruption event in respect of such Underlying, as described herein under “Market Disruption Events.” The Valuation Date is subject to postponement in respect of each Underlying if such date is not an underlying business day for such Underlying or as a result of a market disruption event in respect of such Underlying, as described in the accompanying product supplement under “Description of the Securities—Market disruption events”. The Interest Payment Dates including the Maturity Date are subject to postponement, each as described herein, if such date is not a business day or if the determination of the closing level for any Underlying on the corresponding Observation Date or the Valuation Date, as relevant, is postponed because such date is not a trading day or an underlying business day for any Underlying, as applicable, or as a result of a market disruption event in respect of any Underlying.

Our Central Index Key, or CIK, on the SEC website is 1053092. As used in this pricing supplement, the “Company,” “we,” “us,” or “our” refers to Credit Suisse.

This pricing supplement, together with the documents listed above, contains the terms of the securities and supersedes all other prior or contemporaneous oral statements as well as any other written materials including preliminary or indicative pricing terms, fact sheets, correspondence, trade ideas, structures for implementation, sample structures, brochures or other educational materials of ours. You should carefully consider, among other things, the matters set forth in “Risk Factors” in the product supplement and “Selected Risk Considerations” in this pricing supplement, as the securities involve risks not associated with conventional debt securities. You should consult your investment, legal, tax, accounting and other advisors before deciding to invest in the securities.

Hypothetical Redemption Amounts and Total Payments on the Securities

The tables and examples below illustrate hypothetical Redemption Amounts payable at maturity and, in the case of the tables, total payments over the term of the securities (which include both payments at maturity and the total interest paid on the securities) on a $1,000 investment in the securities for a range of Underlying Returns of the Lowest Performing Underlying, both in the event a Knock-In Event does not occur and in the event a Knock-In Event does occur. The tables and examples assume that (i) the securities are not redeemed prior to maturity, (ii) the Applicable Rate is 11.25% per annum if a Knock-In Event does not occur (approximately 8.4375% over the term of the securities) and 3.0% per annum if a Knock-In Event occurs (approximately 2.25% over the term of the securities), (iii) the term of the securities is exactly nine months and (iv) the Knock-In Level for each Underlying is 65% of the Initial Level of such Underlying. In addition, the examples below assume that the Initial Level is 850 for RTY, $48 for EEM and $41 for USO. The examples are intended to illustrate hypothetical calculations of only the Redemption Amount and do not illustrate the calculation or payment of any individual interest payment. The Redemption Amounts and total payment amounts set forth below are provided for illustration purposes only. The actual Redemption Amounts and total payments applicable to a purchaser of the securities will depend on several variables, including, but not limited to (a) whether the closing level of any Underlying is less than or equal to its Knock-In Level on any trading day for that Underlying during any Observation Period and (b) the Final Level of the Lowest Performing Underlying determined on the Valuation Date. It is not possible to predict whether a Knock-In Event will occur, and in the event that there is a Knock-In Event, whether and by how much the Final Level of the Lowest Performing Underlying will decrease in comparison to its Initial Level. Any payment on the securities is subject to our ability to pay our obligations as they become due. The numbers appearing in the following tables and examples have been rounded for ease of analysis.

$1,000	−50%	−50%	$500	$63.75	$563.75

Example 1: A Knock-In Event occurs because the closing level of one Underlying reaches its Knock-In Level during an Observation Period; and the Final Level of the Lowest Performing Underlying is less than its Initial Level.

Underlying	Initial Level	Lowest closing level of the Underlying during the Observation Period	Final Level on the Valuation Date
RTY	850	552.50 (65% of Initial Level)	552.50 (65% of Initial Level)
EEM	$48	$48.00 (100% of Initial Level)	$52.80 (110% of Initial Level)
USO	$41	$28.70 (70% of Initial Level)	$28.70 (70% of Initial Level)

Since the closing level of RTY reaches its Knock-In Level during an Observation Period, a Knock-In Event occurs. RTY is also the Lowest Performing Underlying.

Therefore, the Underlying Return of the Lowest Performing Underlying will equal:

Final Level of RTY – Initial Level of RTY

Initial Level of RTY

; subject to a maximum of 0.00

= (552.50 – 850)/850 = −0.35

The Redemption Amount = principal amount of the securities × (1 + Underlying Return of the Lowest Performing Underlying)

= $1,000 × (1 – 0.35) = $650

Example 2: A Knock-In Event occurs because the closing level of one Underlying reaches its Knock-In Level during an Observation Period; the Lowest Performing Underlying never reaches or falls below its Knock-In Level during any Observation Period; and the Final Level of the Lowest Performing Underlying is less than its Initial Level.

Underlying	Initial Level	Lowest closing level of the Underlying during the Observation Period	Final Level on the Valuation Date
RTY	850	680.00 (80% of Initial Level)	935.00 (110% of Initial Level)
EEM	$48	$36.96 (77% of Initial Level)	$36.96 (77% of Initial Level)
USO	$41	$26.65 (65% of Initial Level)	$45.10 (110% of Initial Level)

Since the closing level of USO reaches its Knock-In Level, a Knock-In Event occurs. EEM is the Lowest Performing Underlying, even though its closing level never reaches or falls below its Knock-In Level during an Observation Period.

Therefore, the Underlying Return of the Lowest Performing Underlying will equal:

Final Level of EEM – Initial Level of EEM

Initial Level of EEM

; subject to a maximum of 0.00

= ($36.96 – $48)/$48 = −0.23

The Redemption Amount = principal amount of the securities × (1 + Underlying Return of the Lowest Performing Underlying)

= $1,000 × (1 − 0.23) = $770

Example 3: A Knock-In Event occurs because the closing level of one Underlying reaches its Knock-In Level during an Observation Period; and the Final Level of the Lowest Performing Underlying is greater than its Initial Level.

Underlying	Initial Level	Lowest closing level of the Underlying during the Observation Period	Final Level on the Valuation Date
RTY	850	595.00 (70% of Initial Level)	1,020.00 (120% of Initial Level)
EEM	$48	$43.20 (90% of Initial Level)	$57.60 (120% of Initial Level)
USO	$41	$26.65 (65% of Initial Level)	$45.10 (110% of Initial Level)

Since the closing level of USO reaches its Knock-In Level during an Observation Period, a Knock-In Event occurs. USO is also the Lowest Performing Underlying.

Therefore, the Underlying Return of the Lowest Performing Underlying will equal:

Final Level of USO – Initial Level of USO

Initial Level of USO

; subject to a maximum of 0.00

= ($45.10 – $41)/$41 = 0.10

BUT 0.10 is greater than the maximum of 0.00, so the Underlying Return of the Lowest Performing Underlying is 0.00.

The Redemption Amount = principal amount of the securities × (1 + Underlying Return of the Lowest Performing Underlying)

= $1,000 × (1 + 0.00) = $1,000

Example 4: A Knock-In Event does not occur.

Underlying	Initial Level	Lowest closing level of the Underlying during the Observation Period	Final Level on the Valuation Date
RTY	850	654.50 (77% of Initial Level)	935.00 (110% of Initial Level)
EEM	$48	$37.44 (78% of Initial Level)	$52.80 (110% of Initial Level)
USO	$41	$30.75 (75% of Initial Level)	$45.10 (110% of Initial Level)

Since the closing level of each Underlying did not reach or fall below its Knock-In Level, a Knock-In Event does not occur.

Therefore, the Redemption Amount equals $1,000.

Selected Risk Considerations

An investment in the securities involves significant risks. Investing in the securities is not equivalent to investing directly in the Underlyings. These risks are explained in more detail in the “Risk Factors” section of the accompanying product supplement.

•

YOU MAY RECEIVE LESS THAN THE PRINCIPAL AMOUNT AT MATURITY – You may receive less at maturity than you originally invested in the securities, or you may receive nothing, excluding any accrued or unpaid interest. If a Knock-In Event occurs during any Observation Period and the Final Level of the Lowest Performing Underlying is less than its Initial Level, you will not receive the maximum amount of interest payable on the securities and you will be fully exposed to any depreciation in the Lowest Performing Underlying. In this case, the Redemption Amount you will be entitled to receive will be less than the principal amount of the securities, and you could lose your entire investment. It is not possible to predict whether a Knock-In Event will occur and, in the event that there is a Knock-In Event, whether and by how much the Final Level of the Lowest Performing Underlying will decrease in comparison to its Initial Level. Any payment on the securities is subject to our ability to pay our obligations as they become due.

•

THE SECURITIES WILL NOT PAY MORE THAN THE PRINCIPAL AMOUNT, PLUS ACCRUED AND UNPAID INTEREST AT THE APPLICABLE RATE, AT MATURITY OR UPON EARLY REDEMPTION – The securities will not pay more than the principal amount, plus accrued and unpaid interest, at maturity or upon early redemption. If the Final Level of each Underlying is greater than its respective Initial Level (regardless of whether a Knock-In Event has occurred), you will not receive the appreciation of any Underlying. Assuming the securities are held to maturity and the term of the securities is exactly nine months, the maximum amount payable with respect to the securities is expected to be $1,084.38 (to be determined on the Trade Date) for each $1,000 principal amount of the securities.

•

THE SECURITIES ARE SUBJECT TO THE CREDIT RISK OF CREDIT SUISSE – Although the return on the securities will be based on the performance of the Underlyings, the payment of any amount due on the securities, including any applicable interest payments, early redemption payment or payment at maturity, is subject to the credit risk of Credit Suisse. Investors are dependent on our ability to pay all amounts due on the securities and, therefore, investors are subject to our credit risk. In addition, any decline in our credit ratings, any adverse changes in the market’s view of our creditworthiness or any increase in our credit spreads is likely to adversely affect the value of the securities prior to maturity.

•

IF A KNOCK-IN EVENT OCCURS DURING ANY QUARTERLY OBSERVATION PERIOD, THE APPLICABLE RATE FOR THE CORRESPONDING QUARTERLY INTEREST PERIOD AND EACH SUBSEQUENT INTEREST PERIOD IS EXPECTED TO BE 3.0% PER ANNUM – If a Knock-In Event occurs during any quarterly Observation Period, the Applicable Rate for the corresponding quarterly interest period and each subsequent interest period is expected to be 3.0% per annum (approximately 2.25% over the term of the securities and to be determined on the Trade Date). For example, if a Knock-In Event occurs during the period from the Trade Date to the first Observation Date, the Applicable Rate per annum for each interest period is expected to be 3.0% and the maximum amount of interest you will be entitled to receive, assuming the term of the securities is exactly nine months, is expected to be $22.50 per $1,000 principal amount of the securities.

•

IF A KNOCK-IN EVENT OCCURS, YOUR RETURN WILL BE BASED ON THE INDIVIDUAL PERFORMANCE OF THE LOWEST PERFORMING UNDERLYING – If a Knock-In Event occurs, your return will be based on the individual performance of the Lowest Performing Underlying. This will be true even if the closing level of the Lowest Performing Underlying never reached or fell below its Knock-In Level on any trading day during any Observation Period.

•

THE REDEMPTION AMOUNT PAYABLE AT MATURITY WILL BE LESS THAN THE PRINCIPAL AMOUNT OF THE SECURITIES EVEN IF A KNOCK-IN EVENT OCCURS WITH RESPECT TO ONLY ONE UNDERLYING AND THE FINAL LEVEL OF ONLY ONE UNDERLYING FALLS BELOW ITS INITIAL LEVEL – Even if the closing level of only one Underlying is less than or equal to its Knock-In Level on any trading day for that Underlying during any Observation Period, a Knock-In

Event will have occurred. In this case, the Redemption Amount payable at maturity will be less than the principal amount of the securities if, in addition to the occurrence of a Knock-In Event, the Final Level of just one Underlying is less than its Initial Level. This will be true even if the closing level of the Lowest Performing Underlying was never less than or equal to its Knock-In Level on any trading day for that Underlying during any Observation Period.

•

THE SECURITIES ARE SUBJECT TO A POTENTIAL EARLY REDEMPTION, WHICH WOULD LIMIT YOUR ABILITY TO ACCRUE INTEREST OVER THE FULL TERM OF THE SECURITIES – The securities are subject to a potential early redemption. The securities may be redeemed on any Interest Payment Date scheduled to occur on or after August 22, 2011, upon at least three business days notice. If the securities are redeemed prior to the Maturity Date, you will be entitled to receive the principal amount of your securities and any accrued but unpaid interest payable at the Applicable Rate on that Interest Payment Date. In this case, you will lose the opportunity to continue to accrue and be paid interest from the Early Redemption Date to the scheduled Maturity Date. If the securities are redeemed prior to the Maturity Date, you may be unable to invest in other securities with a similar level of risk that yield as much interest as the securities.

•

SINCE THE SECURITIES ARE LINKED TO THE PERFORMANCE OF MORE THAN ONE UNDERLYING, YOU WILL BE FULLY EXPOSED TO THE RISK OF FLUCTUATIONS IN THE LEVEL OF EACH UNDERLYING – Since the securities are linked to the performance of more than one Underlying, the securities will be linked to the individual performance of each Underlying. Because the securities are not linked to a basket, in which the risk is mitigated and diversified among all of the components of a basket, you will be exposed to the risk of fluctuations in the levels of the Underlyings to the same degree for each Underlying. For example, in the case of securities linked to a basket, the return would depend on the weighted aggregate performance of the basket components as reflected by the basket return. Thus, the depreciation of any basket component could be mitigated by the appreciation of another basket component, to the extent of the weightings of such components in the basket. However, in the case of securities linked to the lowest performing of each of three Underlyings, the individual performance of each Underlying is not combined to calculate your return and the depreciation of any Underlying is not mitigated by the appreciation of any other Underlying. Instead, the Redemption Amount payable at maturity depends on the lowest performing of the three Underlyings to which the securities are linked.

THERE ARE RISKS ASSOCIATED WITH THE iSHARES MSCI EMERGING MARKETS INDEX FUND AND THE UNITED STATES OIL FUND, LP – Although shares of the iShares MSCI Emerging Markets Index Fund and the United States Oil Fund, LP (each, a “Reference Fund”) are listed for trading on a national securities exchange and a number of similar products have been traded on various national securities exchanges for varying periods of time, there is no assurance that an active trading market will continue for the shares of either Reference Fund or that there will be liquidity in the trading market. The Reference Funds are subject to management risk, which is the risk that the Reference Funds’ investment strategy, the implementation of which is subject to a number of constraints, may not produce the intended results. Pursuant to the Reference Funds’ investment strategy or otherwise, the investment advisor for such Reference Fund may add, delete or substitute the components held by such Reference Fund. Any of these actions could adversely affect the price of the shares of the Reference Funds and consequently the value of the securities. For additional information about the United States Oil Fund, LP, see the information set forth under “The United States Oil Fund, LP” herein and for additional information about the iShares® MSCI Emerging Markets Index Fund, see information set forth under “The Reference Funds—The iShares® Funds—The iShares® MSCI Emerging Markets Index Fund” in the accompanying underlying supplement.

•

THE PERFORMANCE OF THE iSHARES® MSCI EMERGING MARKETS INDEX FUND MAY NOT CORRELATE TO THE PERFORMANCE OF THE TRACKED INDEX – The iShares® MSCI Emerging Markets Index Fund will generally invest in all of the equity securities included in the MSCI Emerging Markets Index, the “Tracked Index” for the iShares® MSCI Emerging Markets Index Fund. There may, however, be instances where the iShares® MSCI Emerging Markets Index Fund’s investment advisor, may choose to overweight another stock in the Tracked Index, purchase securities not included in the Tracked Index that the investment advisor believes are appropriate to substitute for a security included in the Tracked Index or utilize various combinations of other available investment techniques in seeking to track accurately the Tracked Index. In addition, the

performance of the iShares® MSCI Emerging Markets Index Fund will reflect additional transaction costs and fees that are not included in the calculation of the Tracked Index. Also, corporate actions with respect to the equity securities (such as mergers and spin-offs) may impact the variance between the iShares® MSCI Emerging Markets Index Fund and the Tracked Index. Finally, because the shares of the iShares® MSCI Emerging Markets Index Fund are traded on a national securities exchange and are subject to market supply and investor demand, the market value of one share of the iShares® MSCI Emerging Markets Index Fund may differ from the net asset value per share of the iShares® MSCI Emerging Markets Index Fund. For these reasons, the performance of the iShares® MSCI Emerging Markets Index Fund may not correlate with the performance of the Tracked Index.

•

NON-U.S. SECURITIES MARKETS RISKS – The equity securities comprising the iShares® MSCI Emerging Markets Index Fund are issued by foreign companies in foreign securities markets. These equity securities may be more volatile than domestic stocks and may be subject to different political, market, economic, exchange rate, regulatory and other risks which may have a negative impact on the performance of the securities.

•

CURRENCY EXCHANGE RISK – The securities, which are denominated in U.S. dollars, are subject to currency exchange risk through their exposure to the performance of the iShares® MSCI Emerging Markets Index Fund, which measures the performance of certain foreign stocks. Currency markets may be highly volatile, particularly in relation to emerging or developing nations’ currencies and, in certain market conditions, also in relation to developed nations’ currencies. Significant changes, including changes in liquidity and prices, can occur in such markets within very short periods of time. Foreign currency rate risks include, but are not limited to, convertibility risk and market volatility and potential interference by foreign governments through regulation of local markets, foreign investment or particular transactions in foreign currency. These factors may adversely affect the values of the equity securities comprising the iShares® MSCI Emerging Markets Index Fund, the level of the iShares® MSCI Emerging Markets Index Fund and the value of the securities.

•

THE PERFORMANCE OF THE UNITED STATES OIL FUND, LP MAY NOT FULLY REPLICATE THE PERFORMANCE OF THE PRICE OF WTI LIGHT, SWEET CRUDE OIL – United States Commodity Funds, LLC, the general partner of the United States Oil Fund, LP, is responsible for investing the assets of the United States Oil Fund, LP in accordance with the objectives and policies of the United States Oil Fund, LP. The assets of the United States Oil Fund, LP consist primarily of investments in futures contracts for light, sweet crude oil, other types of crude oil, heating oil, gasoline, natural gas, and other petroleum-based fuels that are traded on the New York Mercantile Exchange, ICE Futures or other U.S. and foreign exchanges (collectively, “oil futures contracts”) and other oil interests such as cash-settled options on oil futures contracts, forward contracts for oil, and over-the-counter transactions that are based on the price of oil, other petroleum-based fuels, oil futures contracts and indices based on the foregoing (collectively, “other oil interests” and together with oil futures contracts, “oil interests”). The United States Oil Fund, LP seeks to achieve its investment objective by investing in a mix of oil futures contracts and other oil interests such that changes in the net asset value of the United States Oil Fund, LP will closely track the changes in the price of a specified oil futures contract (the “benchmark oil futures contract”). The United States Oil Fund, LP’s general partner believes that the benchmark oil futures contract historically has exhibited a close correlation with the spot price of light, sweet crude oil. There is no assurance that the general partner of the United States Oil Fund, LP will successfully implement its investment strategy and there is a risk that changes in the price of United States Oil Fund, LP units will not closely track changes in the spot price of WTI light, sweet crude oil. This could happen if the price of the units does not correlate closely with the United States Oil Fund, LP’s net asset value; changes in the United States Oil Fund, LP’s net asset value do not closely correlate with changes in the price of the benchmark oil futures contract; or changes in the price of the benchmark oil futures contract do not closely correlate with changes in the cash or spot price of light, sweet crude oil.

•

RISKS ASSOCIATED WITH INVESTMENTS IN SECURITIES WITH CONCENTRATION IN ENERGY COMMODITIES – Market prices of the commodities and commodity futures contracts comprising the United States Oil Fund, LP tend to be highly volatile. Commodity market prices are not related to the value of a future income or earnings stream, as tends to be the case with fixed-income and equity investments, but are subject to rapid fluctuations based on numerous factors, including changes in supply and demand relationships, governmental programs and policies, national and

international monetary, trade, political and economic events, changes in interest and exchange rates, speculation and trading activities in commodities and related contracts, drought, floods, weather, and agricultural, trade, fiscal and exchange control policies, embargoes and tariffs. The markets for many commodities is also highly cyclical. Demand for refined petroleum products by consumers, as well as the agricultural, manufacturing and transportation industries, affects the price of energy commodities. Sudden disruptions in the supplies of energy commodities, such as those caused by war, natural events, accidents or acts of terrorism, may cause prices of energy commodities futures contracts to become extremely volatile and unpredictable. Also, sudden and dramatic changes in the futures market may occur, for example, upon a cessation of hostilities that may exist in countries producing energy commodities, the introduction of new or previously withheld supplies into the market or the introduction of substitute products or commodities. In particular, supplies of crude oil may increase or decrease depending on, among other factors, production decisions by the Organization of Oil and Petroleum Exporting Countries (“OPEC”) and other crude oil producers. Crude oil prices are determined with significant influence by OPEC, which has the capacity to influence oil prices worldwide because its members possess a significant portion of the world’s oil supply. Crude oil prices are generally more volatile and subject to dislocation than prices of other commodities. Demand for energy commodities such as crude oil is generally linked to economic activity, and will tend to reflect general economic conditions.

These factors may have a larger impact on commodity prices and commodity-linked instruments than on traditional fixed-income and equity securities. These variables may create additional investment risks that cause the value of the securities to be more volatile than the values of traditional securities. These and other factors may affect the price of the United States Oil Fund, LP, and thus the value of your securities, in unpredictable or unanticipated ways. The high volatility and cyclical nature of commodity markets may render such an investment inappropriate as the focus of an investment portfolio.

•

THE SECURITIES ARE NOT SUBJECT TO REGULATION BY THE COMMODITY FUTURES TRADING COMMISSION – The proceeds to be received by us from the sale of the securities will not be used to purchase or sell any commodities futures contracts or options on futures contracts for your benefit. An investment in the securities thus does not constitute either an investment in futures contracts, options on futures contracts or in a collective investment vehicle that trades in these futures contracts (i.e., the securities will not constitute a direct or indirect investment by you in the futures contracts), and you will not benefit from the regulatory protections of the Commodity Futures Trading Commission, commonly referred to as the “CFTC.” The Issuer is not registered with the CFTC as a futures commission merchant and you will not benefit from the CFTC’s or any other non-U.S. regulatory authority’s regulatory protections afforded to persons who trade in futures contracts on a regulated futures exchange through a registered futures commission merchant. Unlike an investment in the securities, an investment in a collective investment vehicle that invests in futures contracts on behalf of its participants may be subject to regulation as a commodity pool and its operator may be required to be registered with and regulated by the CFTC as a commodity pool operator, or qualify for an exemption from the registration requirement. Because the securities will not be interests in a commodity pool, the securities will not be regulated by the CFTC as a commodity pool, we will not be registered with the CFTC as a commodity pool operator, and you will not benefit from the CFTC’s or any non-U.S. regulatory authority’s regulatory protections afforded to persons who invest in regulated commodity pools.

•

CERTAIN BUILT-IN COSTS ARE LIKELY TO ADVERSELY AFFECT THE VALUE OF THE SECURITIES PRIOR TO MATURITY – While the payment at maturity described in this pricing supplement is based on the full principal amount of your securities, the original issue price of the securities includes the agent’s commission and the cost of hedging our obligations under the securities through one or more of our affiliates. As a result, the price, if any, at which Credit Suisse (or its affiliates), will be willing to purchase securities from you in secondary market transactions, if at all, will likely be lower than the original issue price, and any sale prior to the Maturity Date could result in a substantial loss to you. The securities are not designed to be short-term trading instruments. Accordingly, you should be able and willing to hold your securities to maturity.

•

NO OWNERSHIP RIGHTS RELATING TO THE UNDERLYINGS – Your return on the securities will not reflect the return you would realize if you actually owned shares of the iShares® MSCI Emerging

Markets Index Fund or the United States Oil Fund, LP and the assets that comprise the Underlyings. The return on your investment, which is based on the percentage change in the Underlyings, is not the same as the total return based on the purchase of the shares of the iShares® MSCI Emerging Markets Index Fund, the United States Oil Fund, LP or the assets that comprise the Underlyings.

•

NO DIVIDEND PAYMENTS OR VOTING RIGHTS – As a holder of the securities, you will not have voting rights or rights to receive cash dividends or other distributions or other rights with respect to the shares of the iShares® MSCI Emerging Markets Index Fund, the United States Oil Fund, LP or the assets that comprise the Underlyings.

•

ANTI-DILUTION PROTECTION IS LIMITED – The calculation agent will make anti-dilution adjustments for certain events affecting the shares of the iShares® MSCI Emerging Markets Index Fund or the United States Oil Fund, LP. However, the calculation agent will not make an adjustment in response to all events that could affect the shares of the iShares® MSCI Emerging Markets Index Fund or the United States Oil Fund, LP. If an event occurs that does not require the calculation agent to make an adjustment, the value of the securities may be materially and adversely affected. For additional information, see “Description of the Securities— Adjustments — For reference funds” in the accompanying product supplement.

•

LACK OF LIQUIDITY – The securities will not be listed on any securities exchange. Credit Suisse (or its affiliates) intends to offer to purchase the securities in the secondary market but is not required to do so. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the securities when you wish to do so. Because other dealers are not likely to make a secondary market for the securities, the price at which you may be able to trade your securities is likely to depend on the price, if any, at which Credit Suisse (or its affiliates) is willing to buy the securities. If you have to sell your securities prior to maturity, you may not be able to do so or you may have to sell them at a substantial loss.

•

POTENTIAL CONFLICTS – We and our affiliates play a variety of roles in connection with the issuance of the securities, including acting as calculation agent and hedging our obligations under the securities. In performing these duties, the economic interests of the calculation agent and other affiliates of ours are potentially adverse to your interests as an investor in the securities.

•

MANY ECONOMIC AND MARKET FACTORS WILL AFFECT THE VALUE OF THE SECURITIES – In addition to the levels of the Underlyings on any trading day during any Observation Period, the value of the securities will be affected by a number of economic and market factors that may either offset or magnify each other, including:

the expected volatility of the Underlyings;

the time to maturity of the securities;

the Early Redemption feature, which is likely to limit the value of the securities;

interest and yield rates in the market generally;

supply and demand trends for crude oil;

investors’ expectations with respect to the rate of inflation;

geopolitical conditions and a variety of economic, financial, political, regulatory or judicial events that affect the components comprising the Underlyings, or markets generally and which may affect the levels of the Underlyings;

the exchange rate and the volatility of the exchange rate between the U.S. dollar and the currencies of the stocks comprising the iShares MSCI Emerging Markets Index Fund and any other currency relevant to the value of the iShares MSCI Emerging Markets Index Fund; and

our creditworthiness, including actual or anticipated downgrades in our credit ratings.

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.

Supplemental Use of Proceeds and Hedging

We intend to use the proceeds of this offering for our general corporate purposes, which may include the refinancing of existing debt outside Switzerland. Some or all of the proceeds we receive from the sale of the securities may be used in connection with hedging our obligations under the securities through one or more of our affiliates. Such hedging or trading activities on or prior to the Trade Date and during the term of the securities (including on the Valuation Date) could adversely affect the value of the Underlyings and, as a result, could decrease the amount you may receive on the securities at maturity. For additional information, see “Use of Proceeds and Hedging” in the accompanying product supplement.

Historical Information

The following graphs set forth the historical performance of the Russell 2000® Index based on the closing level of the Russell 2000 Index from January 1, 2006 through May 9, 2011, the historical performance of the iShares® MSCI Emerging Markets Index Fund based on the closing level of one share of such Underlying from January 1, 2006 through May 9, 2011 and the historical performance of the United States Oil Fund, LP based on the closing level of one share of such Underlying from May 30, 2006 through May 9, 2011. The closing level of the Russell 2000® Index on May 9, 2011 was 842.80. The closing level of one share of the iShares® MSCI Emerging Markets Index Fund on May 9, 2011 was $48.34. The closing level of one share of the United States Oil Fund, LP on May 9, 2011 was $40.87. We obtained the closing levels below from Bloomberg, without independent verification. We make no representation or warranty as to the accuracy or completeness of the information obtained from Bloomberg. You should not take the historical levels of the Underlyings as an indication of future performance of the Underlyings or the securities. The levels of any of the Underlyings may decrease so that a Knock-In Event occurs and at maturity you will receive a Redemption Amount equal to less than the principal amount of the securities. Any payment on the securities is subject to our ability to pay our obligations as they become due. We cannot give you any assurance that the closing levels of the Underlyings will remain above their respective Knock-In Levels during any Observation Period. If the closing level of any Underlying is less than or equal to its Knock-In Level on any trading day for that Underlying during any Observation Period, and the closing level of the Lowest Performing Underlying on the Valuation Date is less than its Initial Level, then you will lose money on your investment.

For additional information about the United States Oil Fund, LP, see the information set forth under “The United States Oil Fund, LP” herein and for additional information about the Russell 2000® Index and the iShares® MSCI Emerging Markets Index Fund, see information set forth under “The Reference Indices—The Russell 2000® Index” and “The Reference Funds—The iShares® Funds—the iShares® MSCI Emerging Markets Index Fund” in the accompanying underlying supplement.

Market Disruption Events

If the calculation agent determines that on any Observation Date, other than the Valuation Date, a market disruption event (as defined in the accompanying product supplement under “Description of the Securities—Market disruption events”) exists in respect of any Underlying or if such day is not a trading day (as defined in the accompanying product supplement under “Description of the Securities—Definitions”) for any Underlying, then the determination of the closing level for such Underlying on such Observation Date will be postponed to the first succeeding trading day for such Underlying on which the calculation agent determines that no market disruption event exists in respect of such Underlying, unless the calculation agent determines that a market disruption event exists in respect of such Underlying on each of the five trading days for such Underlying immediately following such Observation Date. In that case, the closing level for such Underlying on such Observation Date will be determined as of the fifth succeeding trading day for such Underlying following such Observation Date (such fifth trading day, the “calculation date”), notwithstanding the market disruption event in respect of such Underlying, and:

•

if a market disruption event has occurred and is continuing with respect to the Russell 2000 Index (the “Reference Index”), the calculation agent will determine the closing level for the Reference Index on that calculation date in accordance with the formula for and method of calculating the Reference Index last in effect prior to the commencement of the market disruption event in respect of the Reference Index using exchange traded prices on the relevant exchanges (as determined by the calculation agent in its sole discretion) or, if trading in any component comprising the Reference Index has been materially suspended or materially limited, its good faith estimate of the prices that would have prevailed on such exchanges (as determined by the calculation agent in its sole discretion) but for the suspension or limitation, as of the valuation time on that calculation date, of each component comprising the Reference Index (subject to the provisions described under “Description of the Securities—Changes to the calculation of a reference index” in the accompanying product supplement); and

•

if a market disruption event has occurred and is continuing with respect to a Reference Fund, the calculation agent will determine the closing level for such Reference Fund on that calculation date using its good faith estimate of the settlement prices that would have prevailed on the relevant exchange for such Reference Fund but for the occurrence of a market disruption event (subject to the provisions described under “Description of the Securities—Changes to the calculation of a reference fund” in the accompanying product supplement).

The determination of the closing level for any Underlying not affected by a market disruption event on an Observation Date (other than the Valuation Date) or by an Observation Date (other than the Valuation Date) not being a trading day for such Underlying will occur on such Observation Date. The Valuation Date for any Underlying not affected by a market disruption event will be the scheduled Valuation Date for such Underlying.

If the determination of the closing level for any Underlying on an Observation Date other than the Valuation Date is postponed as a result of a market disruption event as described above to a date on or after the corresponding Interest Payment Date, then such corresponding Interest Payment Date will be postponed to the business day following the latest date to which such determination is so postponed for any Underlying.

If the Valuation Date for any Underlying is postponed as a result of a market disruption event as described in the accompanying product supplement or because the scheduled Valuation Date is not an underlying business day for any Underlying, then the Maturity Date will be postponed to the fifth business day following the latest Valuation Date for any Underlying.

Supplemental Information Regarding Certain United States Federal Income Tax Considerations

The amount of the stated interest rate on the security that constitutes interest on the Deposit (as defined in the accompanying product supplement) equals 0.2906%, and the remaining balance constitutes the Option Premium (as defined in the accompanying product supplement). Please refer to “Certain U.S. Federal Income Tax Considerations” in the accompanying product supplement.

Supplemental Plan of Distribution (Conflicts of Interest)
