	Russell 2000® Index (“RTY”)				RTY	804.05	562.835
Interest Rate:	7.0% per annum. Interest will be calculated on a 30/360 basis.
Interest Payment Dates:	Unless redeemed earlier, interest will be paid quarterly in arrears on July 27, 2012, October 29, 2012, January 28, 2013, April 29, 2013 and the Maturity Date, subject to the modified following business day convention. No interest will accrue or be payable following an Early Redemption.

In this case, the Redemption Amount will be less than or equal to $700 per $1,000 principal amount of securities and you could lose your entire investment.
	•	If a Knock-In Event does not occur, 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:	Prior to the Maturity Date, the Issuer may redeem the securities in whole, but not in part, on any Interest Payment Date scheduled to occur on or after July 27, 2012 upon notice on or before the relevant Early Redemption Notice Date at 100% of the principal amount of the securities, together with the interest payable on that Interest Payment Date.
Early Redemption Notice Dates:	Notice of Early Redemption will be provided prior to the relevant Interest Payment Date on or before July 20, 2012, October 22, 2012, January 18, 2013 or April 22, 2013, as applicable.
Knock-In Event:	A Knock-In Event will occur if the Final Level of either Underlying is less than or equal to its Knock-In Level on the Valuation Date.
Knock-In Level:	For each Underlying, as set forth in the table above.

Final Level:	For each Underlying, the closing level of such Underlying on the Valuation Date.
Valuation Date:†	July 22, 2013
Maturity Date:†	July 29, 2013
Listing:	The securities will not be listed on any securities exchange.
CUSIP:	22546TQS3

† The Valuation Date is subject to postponement if such date is not an underlying business day for either Underlying or as a result of a market disruption event in respect of either Underlying and the Maturity Date is subject to postponement if such date is not a business day or if the Valuation Date is postponed, in each case as described in the accompanying product supplement under “Description of the Securities—Market disruption events.”

Hypothetical Redemption Amounts and Total Payments on the Securities

The table and examples below illustrate hypothetical Redemption Amounts payable at maturity and, in the case of the table, 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. The table and examples reflect that the Interest Rate applicable to the securities is 7.0% per annum and assume that (i) the securities are not redeemed prior to maturity, (ii) the term of the securities is exactly 15 months and (iii) the Knock-In Level for each Underlying is 70% of the Initial Level of such Underlying. In addition, the examples below assume that the Initial Level is 1400 for SPX and 830 for RTY. 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 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, 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 table and examples have been rounded for ease of analysis.

The following examples illustrate how the Redemption Amount is calculated.

Example 1:

Underlying	Initial Level	Final Level
SPX	1400	1540.00 (110% of Initial Level)
RTY	830	581.00 (70% of Initial Level)

Since the closing level of RTY on the Valuation Date is equal to its Knock-In Level, 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

= (581.00 – 830) / 830 = −0.30

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

= $1,000 × (1 – 0.30) = $700

Example 2:

Underlying	Initial Level	Final Level
SPX	1400	700.00 (50% of Initial Level)
RTY	830	581.00 (70% of Initial Level)

Since the closing level of RTY on the Valuation Date is equal to its Knock-In Level and the closing level of SPX on the Valuation Date is less than its Knock-In Level, a Knock-In Event occurs. SPX is the Lowest Performing Underlying because it is the Underlying with the lowest Underlying Return.

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

Final Level of SPX – Initial Level of SPX

Initial Level of SPX

= (700.00 – 1400) / 1400 = −0.50

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

= $1,000 × (1 – 0.50) = $500

Example 3:

Underlying	Initial Level	Final Level
SPX	1400	1540 (110% of Initial Level)
RTY	830	913.00 (110% of Initial Level)

Since the closing level of each Underlying on the Valuation Date is not less than or equal to 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 the Final Level of either Underlying is less than its Knock-In Level, 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 will lose your entire investment if the level of the Lowest Performing Underlying falls to zero. It is not possible to predict whether a Knock-In Event will occur, and in the event that there is a Knock-In Event, 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 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, you will not receive the appreciation of either Underlying. Assuming the securities are held to maturity and the term of the securities is exactly 15 months, the maximum amount payable with respect to the securities will not exceed $1,087.50 for each $1,000 principal amount of 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, 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. In such case, your return will be negative even if a Knock-In Event occurs with respect to only one Underlying.

• 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. Prior to maturity, the securities may be redeemed on any Interest Payment Date scheduled to occur on or after July 27, 2012, upon notice on or before the relevant Early Redemption Notice Date. 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 on that Interest Payment Date. In this case, you will lose the opportunity to continue to accrue and be paid interest from the date of Early Redemption 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.

4

• 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 case 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 Underlying, 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 Underlyings to which the securities are linked.

• 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 the equity securities 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 shares of the equity securities 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 equity securities that comprise the Underlyings.

• 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.

5

• MANY ECONOMIC AND MARKET FACTORS WILL AFFECT THE VALUE OF THE SECURITIES — In addition to the levels of the Underlyings on any trading day, 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:

o the expected volatility of the Underlyings;

o the time to maturity of the securities;

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

o interest and yield rates in the market generally;

o investors’ expectations with respect to the rate of inflation;

o 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; and

o 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 further information, please refer to “Supplemental Use of Proceeds and Hedging” in the accompanying product supplement.

Historical Information

The following graphs set forth the historical performance of the Underlyings based on the closing levels of such Underlyings from January 1, 2007 through April 20, 2012. The closing level of the S&P 500® Index on April 20, 2012 was 1378.53. The closing level of the Russell 2000® Index on April 20, 2012 was 804.05. 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 either 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 Final Level of each Underlying will remain above its Knock-In Level. If the closing level of either Underlying on the Valuation Date is less than or equal to its Knock-In Level, then you will lose money on your investment.

Foradditional information on the S&P 500® Index, see “The Reference Indices—The S&P® Indices—The S&P 500® Index” in the accompanying underlying supplement, and for additional information on the Russell 2000® Index, see “The Reference Indices—The Russell 2000® Index” in the accompanying underlying supplement.

Material U.S. Federal Income Tax Considerations

The following discussion summarizes material U.S. federal income tax consequences of owning and disposing of securities that may be relevant to holders of securities that acquire their securities from us as part of the original issuance of the securities.  This discussion applies only to holders that hold their securities as capital assets within the meaning of the Internal Revenue Code of 1986, as amended (the “Code”).  Further, this discussion does not address all of the U.S. federal income tax consequences that may be relevant to you in light of your individual circumstances or if you are subject to special rules, such as if you are:

·           a financial institution,

·           a mutual fund,

·           a tax-exempt organization,

·           a grantor trust,

·           certain U.S. expatriates,

·           an insurance company,

·           a dealer or trader in securities or foreign currencies,

·           a person (including traders in securities) using a mark-to-market method of accounting,

·           a person who holds securities as a hedge or as part of a straddle with another position, constructive sale,conversion transaction or other integrated transaction, or

·           an entity that is treated as a partnership  for U.S. federal income tax purposes.

The discussion is based upon the Code, law, regulations, rulings and decisions, in each case, as available and in effect as of the date hereof, all of which are subject to change, possibly with retroactive effect.  Tax consequences under state, local and foreign laws are not addressed herein.  No ruling from the U.S. Internal Revenue Service (the “IRS”) has been or will be sought as to the U.S. federal income tax consequences of the ownership and disposition of securities, and the following discussion is not binding on the IRS.

You should consult your tax advisor as to the specific tax consequences to you of owning and disposing of securities, including the application of federal, state, local and foreign income and other tax laws based on your particular facts and circumstances.

IRS CIRCULAR 230 REQUIRES THAT WE INFORM YOU THAT ANY TAX STATEMENT HEREIN REGARDING ANY U.S. FEDERAL TAX IS NOT INTENDED OR WRITTEN TO BE USED, AND CANNOT BE USED, BY ANY TAXPAYER FOR THE PURPOSE OF AVOIDING ANY PENALTIES. ANY SUCH STATEMENT HEREIN WAS WRITTEN TO SUPPORT THE MARKETING OR PROMOTION OF THE TRANSACTION(S) OR MATTER(S) TO WHICH THE STATEMENT RELATES.  A PROSPECTIVE INVESTOR (INCLUDING A TAX-EXEMPT INVESTOR) IN THE SECURITIES SHOULD CONSULT ITS OWN TAX ADVISOR IN DETERMINING THE TAX CONSEQUENCES OF AN INVESTMENT IN THE SECURITIES, INCLUDING THE APPLICATION OF STATE, LOCAL OR OTHER TAX LAWS AND THE POSSIBLE EFFECTS OF CHANGES IN FEDERAL OR OTHER TAX LAWS.

Characterization of the Securities

There are no statutory provisions, regulations, published rulings or judicial decisions addressing the characterization for U.S. federal income tax purposes of securities with terms that are substantially the same as those of your securities.  Thus, the characterization of the securities is not certain.  Due to the terms of the securities and the uncertainty of the tax law with respect to characterization of the securities, our special tax counsel, Orrick, Herrington & Sutcliffe LLP, is unable to opine on the characterization of the securities for U.S. federal income tax purposes.  The possible alternative characterizations and risks to investors of such characterizations are discussed below.  Based on the advice of our special tax counsel, we intend to treat the securities, for U.S. federal income tax purposes, as (1) a put option (the “Put Option”) that requires the holder to cash settle against the value of the Underlyings for an amount equal to the Deposit (as defined below) if the either of the Underlyings declines to a defined floor level and ends up equal to or less than its Initial Level and (2) a deposit with us of cash, in an amount equal to the amount paid for a security (the “Deposit”) to secure the holder’s potential obligation to cash settle against the value of the Underlyings.  In the absence of an administrative or judicial ruling to the contrary, we and, by acceptance of a security, each holder agree to treat the securities as

9

consisting of a Deposit and a Put Option with respect to the Underlyings for all U.S. federal income tax purposes.  The balance of this discussion assumes that the securities will be so treated.

Alternative Characterizations of the Securities

You should be aware that the characterization of the securities as described above is not certain, nor is it binding on the IRS or the courts.  Thus, it is possible that the IRS would seek to characterize your securities in a manner that results in tax consequences to you that are different from those described above.  For example, the IRS might assert that securities with a term of more than one year constitute debt instruments that are “contingent payment debt instruments” that are subject to special tax rules under the applicable Treasury regulations governing the recognition of income over the term of your securities.  If the securities were to be treated as contingent payment debt instruments, you would be required to include in income on an economic accrual basis over the term of the securities an amount of interest that is based upon the yield at which we would issue a non-contingent fixed-rate debt instrument with other terms and conditions similar to your securities, or the comparable yield.  The characterization of securities as contingent payment debt instruments under these rules is likely to be adverse.  However, if the securities had a term of one year or less, the rules for short-term debt obligations would apply rather than the rules for contingent payment debt instruments.  Under Treasury regulations, a short-term debt obligation is treated as issued at a discount equal to the difference between all payments on the obligation and the obligation’s issue price.  A cash method U.S. Holder that does not elect to accrue the discount in income currently should include the payments attributable to interest on the security as income upon receipt.  Under these rules, any contingent payment would be taxable upon receipt by a cash basis taxpayer as ordinary interest income.  You should consult your tax advisor regarding the possible tax consequences of characterization of the securities as contingent payment debt instruments or short-term debt obligations.

It is also possible that the IRS would seek to characterize a security as a notional principal contract (an “NPC”).  In general, payments on an NPC are accrued ratably (as ordinary income or deduction, as the case may be) over the period to which they relate income regardless of an investor’s usual method of tax accounting.  Payments made to terminate an NPC (other than perhaps a final scheduled payment) are capital in nature.  Deductions for NPC payments may be limited in certain cases.  Certain payments under an NPC may be treated as U.S. source income.  The IRS could also seek to characterize your securities as Code section 1256 contracts in the event that they are listed on a securities exchange.  In such case, the securities would be marked-to-market at the end of the year and 40% of any gain or loss would be treated as short-term capital gain or loss, and the remaining 60% of any gain or loss would be treated as long-term capital gain or loss.  Alternatively, in the event that the securities have a term of more than one year and reference an equity interest in a “pass-thru entity” within the meaning of Code section 1260 (which includes shares in, among others, an exchange-traded fund, a regulated investment company, a real estate investment trust, a partnership or a trust), the IRS might assert that the securities constitute a “constructive ownership transaction.”  If the securities were treated as a constructive ownership transaction, under Code section 1260, all or a portion of your gain, if any, from the securities would be recharacterized as ordinary income, and you would be required to pay additional tax calculated by reference to interest on the tax on such recharacterized income.  We are not responsible for any adverse consequences that you may experience as a result of any alternative characterization of the securities for U.S. federal income tax or other tax purposes.

You should consult your tax advisor as to the tax consequences of such characterization and any possible alternative characterizations of your securities for U.S. federal income tax purposes.

U.S. Holders

For purposes of this discussion, the term “U.S. Holder,” for U.S. federal income tax purposes, means a beneficial owner of securities that is (1) a citizen or resident of the United States, (2) a corporation (or an entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States or any state thereof or the District of Columbia, (3) an estate, the income of which is subject to U.S. federal income taxation regardless of its source, or (4) a trust, if (a) a court within the United States is able to exercise primary supervision over the administration of such trust and one or more U.S. persons have the authority to control all substantial decisions of the trust or (b) such trust has in effect a valid election to be treated as a domestic trust for U.S. federal income tax purposes.  If a partnership (or an entity treated as a partnership for U.S. federal income tax purposes) holds securities, the U.S. federal income tax treatment of such partnership and a partner in such partnership will generally depend upon the status of the partner and the activities of the partnership.  If you are a partnership, or a partner of a partnership, holding securities, you should consult your tax

10

advisor regarding the tax consequences to you from the partnership's purchase, ownership, and disposition of the securities.

In accordance with the agreed-upon tax treatment described above, each coupon (a “Coupon”) is comprised of a component that is stated interest on the security, which should be treated as interest on the Deposit of 0.5235%, and the balance of the Coupon should be treated as an installment payment of put premium received by the U.S. Holder in respect of the Put Option to us (the “Put Premium”).

Payment of Redemption Amount and Coupons on the Securities

We will treat the Deposit as a debt obligation issued by us.  Accordingly, we will treat each Coupon as consisting of interest of 0.5235% on the Deposit and the balance as an installment payment of Put Premium paid to you.  U.S. Holders should therefore include such interest component of each Coupon in income as received or accrued, based on their method of accounting.

If a Knock-In Event has occurred and the security provides for the payment of the Redemption Amount in cash based on the return of the Underlyings, a U.S. Holder will receive cash equal to the amount described above under  “Key Terms — Redemption Amount”.  A U.S. Holder will be deemed to receive the Deposit and any accrued but unpaid Coupons.  Ordinarily, there should be no gain or loss on the Deposit, and the remainder of this discussion assumes that this will be the case.  If the Final Level of either of the Underlyings is less than its Initial Level and a Knock-In Event has occurred, the Put Option should be deemed to have been exercised at the time of redemption.  In such a case, the difference between the Deposit and the amount received, less accrued but unpaid interest on the Deposit (which will be taxed as described above) is deemed to have been paid to settle the Put Option.  Any loss on the Put Option, calculated as (a) the Deposit, less (b) the Redemption Amount (less accrued but unpaid interest on the Deposit) plus the Put Premium, should be short-term capital loss.

If a Knock-In Event has occurred and the security provides for the payment of the Redemption Amount in physical shares or units of the Underlyings, the U.S. Holder should not recognize any gain or loss with respect to the Put Option (other than with respect to cash received in lieu of fractional shares or units, as described below).  The U.S. Holder should have an adjusted tax basis in all physical shares or units received (including for this purpose any fractional shares or units) equal to the Deposit less the total Put Premium received.  The U.S. Holder’s holding period for any reference shares or units received should start on the day after the delivery of the reference shares or units.  The U.S. Holder should generally recognize short-term capital gain or loss with respect to cash received in lieu of fractional shares or units in an amount equal to the difference between the amount of such cash received and the U.S. Holder’s basis in the fractional shares or units, which should be equal to the U.S. Holder’s basis in all of the reference shares or units (including the fractional shares or units), multiplied by a fraction, the numerator of which is the fractional shares or units and the denominator of which is all of the physical shares or units (including fractional shares or units).

If a Knock-In Event has not occurred, or if the securities are subject to early redemption, a U.S. Holder will receive cash equal the Deposit plus any accrued but unpaid Coupons.  In such a case, the Put Option should be deemed to have expired unexercised and an amount equal to any accrued but unpaid Put Premium should be treated as short-term capital gain.  The interest portion of the Coupons will be taxed as described above.

Sale or Exchange of the Securities

Upon a sale or exchange of a security, a U.S. Holder should allocate the sale proceeds received between the Deposit and the Put Option on the basis of their respective fair market values on the date of sale.  The U.S. Holder should generally recognize gain or loss with respect to the Deposit in an amount equal to the difference between the amount of the sale proceeds allocable to the Deposit (less accrued but unpaid interest on the Deposit which will be taxed as described above under “Payment of Redemption Amount and Coupons on the Securities”) and the U.S. Holder’s adjusted tax basis in the Deposit (which will generally equal the issue price of the security).  Generally, there should be no gain or loss with respect to the Deposit.

A U.S. Holder should generally recognize gain or loss with respect to the Put Option in an amount equal to the difference between the amount of the sale proceeds allocable to the Put Option and the U.S. Holder’s adjusted tax basis in the Put Option.  If the value of the total sale proceeds received (minus accrued but unpaid interest with respect to the Deposit) exceeds the Deposit, then the U.S. Holder should recognize short-term capital gain equal to the amount of remaining sale proceeds allocable to the Put Option.  If the value of the Deposit exceeds

11

the total sale proceeds received (minus accrued but unpaid interest with respect to the Deposit), then the U.S. Holder should be treated as having paid the buyer an amount equal to the amount of such excess in exchange for the buyer’s assumption of the U.S. Holder’s rights and obligations under the Put Option (such excess being referred to as “Deemed Payment”).  In such a case, the U.S. Holder should recognize short-term capital loss in an amount equal to the Deemed Payment made by the U.S. Holder to the buyer with respect to the assumption of the Put Option.

Securities Held Through Foreign Accounts

Under the “Hiring Incentives to Restore Employment Act” (the “Act”) and recently proposed regulations, a 30% withholding tax is imposed on “withholdable payments” and certain “passthru payments” made to foreign financial institutions (and their more than 50% affiliates) unless the payee foreign financial institution agrees, among other things, to disclose the identity of any U.S. individual with an account at the institution (or the institution’s affiliates) and to annually report certain information about such account.  “Withholdable payments” include (1) payments of interest (including original issue discount), dividends, and other items of fixed or determinable annual or periodical gains, profits, and income (“FDAP”), in each case, from sources within the United States, and (2) gross proceeds from the sale of any property of a type which can produce interest or dividends from sources within the United States.  “Passthru payments” generally are certain payments attributable to withholdable payments.  The Act also requires withholding agents making withholdable payments to certain foreign entities that do not disclose the name, address, and taxpayer identification number of any substantial U.S. owners (or certify that they do not have any substantial United States owners) to withhold tax at a rate of 30%.  We will treat payments on the securities as withholdable payments for these purposes.

Withholding under the Act described above will apply to all withholdable payments and certain passthru payments without regard to whether the beneficial owner of the payment is a U.S. person, or would otherwise be entitled to an exemption from the imposition of withholding tax pursuant to an applicable tax treaty with the United States or pursuant to U.S. domestic law.  Unless a foreign financial institution is the beneficial owner of a payment, it will be subject to refund or credit in accordance with the same procedures and limitations applicable to other taxes withheld on FDAP payments provided that the beneficial owner of the payment furnishes such information as the IRS determines is necessary to determine whether such beneficial owner is a United States owned foreign entity and the identity of any substantial United States owners of such entity.  Pursuant to the proposed regulations, the Act’s withholding regime generally will apply to (i) withholdable payments (other than gross proceeds of the type described above) made after December 31, 2013, (ii) payments of gross proceeds of the type described above with respect to a sale or disposition occurring after December 31, 2014, and (iii) passthru payments made after December 31, 2016.  Additionally, the provisions of the Act discussed above generally will not apply to obligations (other than an instrument that is treated as equity for U.S. tax purposes or that lacks a stated expiration or term) that are outstanding on January 1, 2013.  Thus, if you hold your securities through a foreign financial institution or foreign corporation or trust, a portion of any of your payments made after December 31, 2013 may be subject to 30% withholding.

Non-U.S. Holders Generally

The U.S. withholding tax consequences of any Coupon payment in respect of the securities is uncertain.  Given the uncertainty, we will withhold U.S. income tax at a rate of 30% on any Coupon payment.  It may be possible for a holder of the securities that is not a U.S. Holder (a “Non-U.S. Holder”) to take the position that some or all of a Coupon payment is exempt from the 30% U.S. withholding tax or subject to a reduced withholding tax rate under an applicable tax treaty.  Any Non-U.S. Holder taking the position that a Coupon payment is exempt from the 30% withholding tax or eligible for a reduced rate of U.S. withholding tax may seek a refund or credit of any excess amounts withheld by us by filing an appropriate claim for refund with the IRS.

In the case of a Non- U.S. Holder that has no connection with the United States other than holding its securities, payment of the Redemption Amount by us in respect to the securities (except to the extent of the Coupons) will not be subject to U.S. withholding tax, provided that such Non-U.S. Holder complies with applicable certification requirements.  Any gain realized upon the sale or other disposition of the securities by a Non-U.S. Holder generally will not be subject to U.S. federal income tax unless (1) such gain is effectively connected with a U.S. trade or business of such Non-U.S. Holder or (2) in the case of an individual, such individual is present in the United States for 183 days or more in the taxable year of the sale or other disposition and certain other conditions are met.  Any effectively connected gains described in clause (1) above realized by a Non-U.S. Holder that is, or is taxable as, a corporation for U.S. federal income tax purposes may also, under certain circumstances, be

12

subject to an additional branch profits tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty.  Non-U.S. Holders should consult their tax advisors regarding the possibility that any portion of the return with respect to the securities could be characterized as dividend income and be subject to U.S. withholding tax.

Non-U.S. Holders that are subject to U.S. federal income taxation on a net income basis with respect to their investment in the securities should refer to the discussion above relating to U.S. Holders.

Substitute Dividend and Dividend Equivalent Payments

The Act and recently proposed and temporary regulations treat a “dividend equivalent” payment as a dividend from sources within the United States.  Under the Act, unless reduced by an applicable tax treaty with the United States, such payments generally will be subject to U.S. withholding tax.  A “dividend equivalent” payment is (i) a substitute dividend payment made pursuant to a securities lending or a sale-repurchase transaction that (directly or indirectly) is contingent upon, or determined by reference to, the payment of a dividend from sources within the United States, (ii) a payment made pursuant to a “specified notional principal contract” that (directly or indirectly) is contingent upon, or determined by reference to, the payment of a dividend from sources within the United States, and (iii) any other payment determined by the IRS to be substantially similar to a payment described in the preceding clauses (i) and (ii).  Proposed regulations provide criteria for determining whether a notional principal contract will be a specified notional principal contract, effective for payments made after December 31, 2012.

Proposed regulations address whether a payment is a dividend equivalent.  The proposed regulations provide that an equity-linked instrument that provides for a payment that is a substantially similar payment is treated as a notional principal contract for these purposes.  An equity-linked instrument is a financial instrument or combination of financial instruments that references one or more underlying securities to determine its value, including a futures contract, forward contract, option, or other contractual arrangement.  Although it is not certain, an equity-linked instrument could include instruments treated as indebtedness for U.S. federal income tax purposes.  The proposed regulations consider any payment, including the payment of the purchase price or an adjustment to the purchase price, to be a substantially similar payment (and, therefore, a dividend equivalent payment) if made pursuant to an equity-linked instrument that is contingent upon or determined by reference to a dividend (including payments pursuant to a redemption of stock that gives rise to a dividend) from sources within the United States.  The rules for equity-linked instruments under the proposed regulations will be effective for payments made after the rules are finalized.  Where the securities reference an interest in a fixed basket of securities or a “customized index,” each security or component of such basket or customized index is treated as an underlying security in a separate notional principal contract for purposes of determining whether such notional principal contract is a specified notional principal contract or an amount received is a substantially similar payment.

We will treat any portion of a payment on the securities that is substantially similar to a dividend as a dividend equivalent payment, which will be subject to U.S. withholding tax unless reduced by an applicable tax treaty and a properly executed IRS Form W-8 (or other qualifying documentation) is provided.  Investors should consult their tax advisors regarding whether payments on the securities constitute dividend equivalent payments.

U.S. Federal Estate Tax Treatment of Non-U.S. Holders

The securities may be subject to U.S. federal estate tax if an individual Non-U.S. Holder holds the securities at the time of his or her death.  The gross estate of a Non-U.S. Holder domiciled outside the United States includes only property situated in the United States.  Individual Non-U.S. Holders should consult their tax advisors regarding the U.S. federal estate tax consequences of holding the securities at death.

IRS Notice on Certain Financial Transactions

On December 7, 2007, the IRS and the Treasury Department issued Notice 2008-2, in which they stated they are considering issuing new regulations or other guidance on whether holders of an instrument such as the securities should be required to accrue income during the term of the instrument.  The IRS and Treasury Department also requested taxpayer comments on (1) the appropriate method for accruing income or expense (e.g., a mark-to-market methodology or a method resembling the noncontingent bond method), (2) whether income and gain on such an instrument should be ordinary or capital, and (3) whether foreign holders should be subject to withholding tax on any deemed income accrual.  Additionally, unofficial statements made by IRS officials have indicated that they will soon be addressing the treatment of prepaid forward contracts in proposed regulations.

13

Accordingly, it is possible that regulations or other guidance may be issued that require holders of the securities to recognize income in respect of the securities prior to receipt of any payments thereunder or sale thereof.  Any regulations or other guidance that may be issued could result in income and gain (either at maturity or upon sale) in respect of the securities being treated as ordinary income.  It is also possible that a Non-U.S. Holder of the securities could be subject to U.S. withholding tax in respect of the securities under such regulations or other guidance.  It is not possible to determine whether such regulations or other guidance will apply to your securities (possibly on a retroactive basis).  You are urged to consult your tax advisor regarding Notice 2008-2 and its possible impact on you.

Information Reporting Regarding Specified Foreign Financial Assets

The Act and temporary and proposed regulations generally require individual U.S. Holders (“specified individuals”) and “specified domestic entities” with an interest in any “specified foreign financial asset” to file an annual report on new IRS Form 8938 with information relating to the asset, including the maximum value thereof, for any taxable year in which the aggregate value of all such assets is greater than $50,000 on the last day of the taxable year or $75,000 at any time during the taxable year.  Certain individuals are permitted to have an interest in a higher aggregate value of such assets before being required to file a report.  The proposed regulations relating to specified domestic entities apply to taxable years beginning after December 31, 2011.  Under the proposed regulations, “specified domestic entities” are domestic entities that are formed or used for the purposes of holding, directly or indirectly, specified foreign financial assets.  Generally, specified domestic entities are certain closely held corporations and partnerships that meet passive income or passive asset tests and, with certain exceptions, domestic trusts that have a specified individual as a current beneficiary and exceed the reporting threshold.  Specified foreign financial assets include any depository or custodial account held at a foreign financial institution; any debt or equity interest in a foreign financial institution if such interest is not regularly traded on an established securities market; and, if not held at a financial institution, (i) any stock or security issued by a non-U.S. person, (ii) any financial instrument or contract held for investment where the issuer or counterparty is a non-U.S. person, and (iii) any interest in an entity which is a non-U.S. person.

Depending on the aggregate value of your investment in specified foreign financial assets, you may be obligated to file an IRS Form 8938 under this provision if you are an individual U.S. Holder.  Specified domestic entities are not required to file Form 8938 until the proposed regulations are final.  Penalties apply to any failure to file IRS Form 8938.  Additionally, in the event a U.S. Holder (either a specified individual or specified domestic entity) does not file such form, the statute of limitations on the assessment and collection of U.S. federal income taxes of such U.S. Holder for the related tax year may not close before the date which is three years after the date such information is filed. You should consult your own tax advisor as to the possible application to you of this information reporting requirement and related statute of limitations tolling provision.

Backup Withholding and Information Reporting

A holder of the securities (whether a U.S. Holder or a Non-U.S. Holder) may be subject to backup withholding with respect to certain amounts paid to such holder unless it provides a correct taxpayer identification number, complies with certain certification procedures establishing that it is not a U.S. Holder or establishes proof of another applicable exemption, and otherwise complies with applicable requirements of the backup withholding rules.  Backup withholding is not an additional tax.  You can claim a credit against your U.S. federal income tax liability for amounts withheld under the backup withholding rules, and amounts in excess of your liability are refundable if you provide the required information to the IRS in a timely fashion.  A holder of the securities may also be subject to information reporting to the IRS with respect to certain amounts paid to such holder unless it (1) is a Non-U.S. Holder and provides a properly executed IRS Form W-8 (or other qualifying documentation) or (2) otherwise establishes a basis for exemption.

Supplemental Plan of Distribution (Conflicts of Interest)

Under the terms and subject to the conditions contained in a distribution agreement dated May 7, 2007, as amended, which we refer to as the distribution agreement, we have agreed to sell the securities to CSSU. The distribution agreement provides that CSSU is obligated to purchase all of the securities if any are purchased.

CSSU proposes to offer the securities at the offering price set forth on the cover page of this pricing supplement and will receive underwriting discounts and commissions of $15.00 per $1,000 principal amount of securities. CSSU may re-allow some or all of the discount on the principal amount per security on sales of such securities by other brokers or dealers. If all of the securities are not sold at the initial offering price, CSSU may change the public offering price and other selling terms.

In addition, Credit Suisse International, an affiliate of Credit Suisse, may pay referral fees of up to $5.50 per $1,000 principal amount of securities in connection with the distribution of the securities. An affiliate of Credit Suisse has paid or may pay in the future a fixed amount to broker-dealers in connection with the costs of implementing systems to support these securities.

We expect that delivery of the securities will be made against payment for the securities on April 27, 2012, which will be the fifth business day following the Trade Date for the securities (this settlement cycle being referred to as T+5). Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in three business days, unless the parties to that trade expressly agree otherwise. Accordingly, purchasers who wish to trade the securities on the Trade Date or the following business day will be required to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement and should consult their own advisors.

The agent for this offering, CSSU, is our affiliate. In accordance with FINRA Rule 5121, CSSU may not make sales in this offering to any of its discretionary accounts without the prior written approval of the customer. A portion of the net proceeds from the sale of the securities will be used by CSSU or one of its affiliates in connection with hedging our obligations under the securities. For further information, please refer to “Underwriting (Conflicts of Interest)” in the accompanying product supplement.
