Market-Linked Step Up Notes

Summary

The Market-Linked Step Up Notes Linked to an Equity Index Basket, due July , 2019 (the “notes”) are our senior unsecured debt securities. The notes are not guaranteed or insured by the Federal Deposit Insurance Corporation or any other governmental agency of the United States, Switzerland or any other jurisdiction and are not secured by collateral. The notes will rank equally with all of our other unsecured and unsubordinated debt. Any payments due on the notes, including any repayment of principal, will be subject to the credit risk of Credit Suisse. The notes provide you with a Step Up Payment if the Ending Value of the Market Measure, which is the equity index basket described below (the “Basket”), is equal to or greater than its Starting Value, but is not greater than the Step Up Value. If the Ending Value is greater than the Step Up Value, you will participate on a 1-for-1 basis in the increase in the value of the Basket above the Starting Value. If the Ending Value is less than the Starting Value but greater than or equal to the Threshold Value, you will receive the principal amount of your notes. If the Ending Value is less than the Threshold Value, you will lose a portion, which could be significant, of the principal amount of your notes. Payments on the notes, including the amount you receive at maturity, will be calculated based on the $10 principal amount per unit and will depend on the performance of the Basket, subject to our credit risk. See “Terms of the Notes” below.

The Basket is comprised of the EURO STOXX 50^® Index and the Dow Jones Industrial Average^SM (each, a “Basket Component”). On the pricing date, each of the Basket Components will be given an initial weight of 50%.

The economic terms of the notes (including the Step Up Payment) are based on the rate we are currently paying to borrow funds through the issuance of market-linked notes (our “internal funding rate”) and the economic terms of certain related hedging arrangements. Our internal funding rate for market-linked notes is typically lower than a rate reflecting the yield on our conventional debt securities of similar maturity in the secondary market (our “secondary market credit rate”). This difference in borrowing rate, as well as the underwriting discount and the hedging related charge described below, will reduce the economic terms of the notes to you and the initial estimated value of the notes on the pricing date. These costs will be effectively borne by you as an investor in the notes, and will be retained by us and MLPF&S or any of our respective affiliates in connection with our structuring and offering of the notes. Due to these factors, the public offering price you pay to purchase the notes will be greater than the initial estimated value of the notes.

On the cover page of this term sheet, we have provided the initial estimated value range for the notes. This range of estimated values reflects terms that are not yet fixed and was determined based on our valuation of the theoretical components of the notes in accordance with our pricing models. These include a theoretical bond component valued using our internal funding rate, and theoretical individual option components valued using mid-market pricing. You will not have any interest in, or rights to, the theoretical components we use to determine the estimated value of the notes. The initial estimated value of the notes calculated on the pricing date will be set forth in the final term sheet made available to investors in the notes. For more information about the initial estimated value and the structuring of the notes, see “Structuring the Notes” on page TS-15.

Hypothetical Payout Profile

The below graph is based on hypothetical numbers and values.

Market-Linked Step Up Notes     This graph reflects the returns on the notes based on a Threshold Value of 90% of the Starting Value, a Step Up Payment of $2.20 per unit (the midpoint of the Step Up Payment range of [$1.90 to $2.50]) and a Step Up Value of 122% of the Starting Value (the midpoint of the Step Up Value range of [119% to 125%]). The green line reflects the returns on the notes, while the dotted gray line reflects the returns of a direct investment in the stocks included in the Basket Components, excluding dividends.   This graph has been prepared for purposes of illustration only.
See below table for a further illustration of the range of hypothetical payments at maturity.  

Hypothetical Payments at Maturity

The following table and examples are for purposes of illustration only. They are based on hypothetical values and show hypothetical returns on the notes. The actual amount you receive and the resulting total rate of return will depend on the actual Ending Value, Step Up Value, Step Up Payment, and term of your investment.

The following table is based on the Starting Value of 100, the Threshold Value of 90, a Step Up Value of 122 and a Step Up Payment of $2.20 per unit. It illustrates the effect of a range of Ending Values on the Redemption Amount per unit of the notes and the total rate of return to holders of the notes. The following examples do not take into account any tax consequences from investing in the notes.

Ending Value	Percentage Change from the Starting Value to the Ending Value	Redemption Amount per Unit	Total Rate of Return on the Notes

(2) The Starting Value will be set to 100.00 on the pricing date.

(3) This amount represents the sum of the principal amount and the hypothetical Step Up Payment of $2.20.

(4) This is the hypothetical Step Up Value.

For recent hypothetical levels of the Basket, see “The Basket” section below. For recent actual levels of the Basket Components, see “The Basket Components” section below. Each Basket Component is a price return index and as such the Ending Value will not include any income generated by dividends paid on the stocks included in either of the Basket Components, which you would otherwise be entitled to receive if you invested in those stocks directly. In addition, all payments on the notes are subject to issuer credit risk.

Redemption Amount Calculation Examples

Example 1
The Ending Value is 80.00, or 80.00% of the Starting Value:
Starting Value:   100.00
Threshold Value: 90.00
Ending Value:     80.00
	Redemption Amount per unit

Example 2

The Ending Value is 95.00, or 95.00% of the Starting Value:

Starting Value:   100.00

Threshold Value: 90.00

Ending Value:     95.00

Redemption Amount per unit = $10.00, the principal amount, since the Ending Value is less than the Starting Value, but is equal to or greater than the Threshold Value.

Example 3
The Ending Value is 110.00, or 110.00% of the Starting Value:
Starting Value:   100.00
Step Up Value:   122.00
Ending Value:     110.00
	Redemption Amount per unit, the principal amount plus the Step Up Payment, since the Ending Value is equal to or greater than the Starting Value, but less than the Step Up Value.

Example 4
The Ending Value is 140.00, or 140.00% of the Starting Value:
Starting Value:   100.00
Step Up Value:   122.00
Ending Value:     140.00
	Redemption Amount per unit

Risk Factors

There are important differences between the notes and a conventional debt security. An investment in the notes involves significant risks, including those listed below. You should carefully review the more detailed explanation of risks relating to the notes in the “Risk Factors” sections beginning on page PS-7 of product supplement EQUITY INDICES SUN-2 identified above. We also urge you to consult your investment, legal, tax, accounting, and other advisors before you invest in the notes.

§ Depending on the performance of the Basket as measured shortly before the maturity date, your investment may result in a loss; there is no guaranteed return of principal.

§ Your return on the notes may be less than the yield you could earn by owning a conventional fixed or floating rate debt security of comparable maturity.

§ Payments on the notes are subject to our credit risk, and actual or perceived changes in our creditworthiness are expected to affect the value of the notes. If we become insolvent or are unable to pay our obligations, you may lose your entire investment.

§ Your investment return may be less than a comparable investment directly in the stocks included in the Basket Components.

§ The initial estimated value of the notes is an estimate only, determined as of a particular point in time by reference to our proprietary pricing models. These pricing models consider certain factors, such as our internal funding rate on the pricing date, interest rates, volatility and time to maturity of the notes, and they rely in part on certain assumptions about future events, which may prove to be incorrect. Because our pricing models may differ from other issuers’ valuation models, and because funding rates taken into account by other issuers may vary materially from the rates used by us (even among issuers with similar creditworthiness), our estimated value may not be comparable to estimated values of similar notes of other issuers.

§ Our internal funding rate for market-linked notes is typically lower than our secondary market credit rates, as further described in “Structuring the Notes” on page TS-15. Because we use our internal funding rate to determine the value of the theoretical bond component, if on the pricing date our internal funding rate is lower than our secondary market credit rates, the initial estimated value of the notes will be greater than if we had used our secondary market credit rates in valuing the notes.

§ The public offering price you pay for the notes will exceed the initial estimated value. This is due to, among other transaction costs, the inclusion in the public offering price of the underwriting discount and the hedging related charge, as further described in “Structuring the Notes” on page TS-15.

§ Assuming no change in market conditions or other relevant factors after the pricing date, the market value of your notes may be lower than the price you paid for them and lower than the initial estimated value. This is due to, among other things, the inclusion in the public offering price of the underwriting discount and the hedging related charge and the internal funding rate we used in pricing the notes, as further described in “Structuring the Notes” on page TS-15. These factors, together with customary bid ask spreads, other transaction costs and various credit, market and economic factors over the term of the notes, including changes in the value of the Basket, are expected to reduce the price at which you may be able to sell the notes in any secondary market and will affect the value of the notes in complex and unpredictable ways.

§ A trading market is not expected to develop for the notes. Neither we nor MLPF&S is obligated to make a market for, or to repurchase, the notes. The initial estimated value does not represent a minimum or maximum price at which we, MLPF&S or any of our affiliates would be willing to purchase your notes in any secondary market (if any exists) at any time. MLPF&S has advised us that any repurchases by them or their affiliates will be made at prices determined by reference to their pricing models and at their discretion, and these prices will include MLPF&S’s trading commissions and mark-ups. If you sell your notes to a dealer other than MLPF&S in a secondary market transaction, the dealer may impose its own discount or commission. MLPF&S has also advised us that, at its discretion and for your benefit, assuming no changes in market conditions from the pricing date, MLPF&S may offer to buy the notes in the secondary market at a price that may exceed the initial estimated value of the notes for a short initial period after the issuance of the notes. That higher price reflects costs that were included in the public offering price of the notes, and that higher price may also be initially used for account statements or otherwise. There is no assurance that any party will be willing to purchase your notes at any price in any secondary market.

§ Our business, hedging and trading activities, and those of MLPF&S and our respective affiliates (including trading in shares of companies included in the Basket Components), and any hedging and trading activities we, MLPF&S or our respective affiliates engage in for our clients’ accounts, may affect the market value and return of the notes and may create conflicts of interest with you.

§ Changes in the level of one of the Basket Components may be offset by changes in the level of the other Basket Component.

§ The index sponsors may adjust their respective Basket Components in a way that affects its level, and have no obligation to consider your interests.

§ You will have no rights of a holder of the securities represented by the Basket Components, and you will not be entitled to receive securities or dividends or other distributions by the issuers of those securities.

§ While we, MLPF&S or our respective affiliates may from time to time own securities of companies included in the Basket Components, we, MLPF&S and our respective affiliates do not control any company included in any Basket Component, and we have not verified any disclosure made by any other company.

§ Your return on the notes may be affected by factors affecting the international securities markets, including economic, financial, social and political conditions.  Specifically, the stocks included in the SX5E are issued by companies located within the Eurozone. The Eurozone is and has been undergoing severe financial stress, and the political, legal and regulatory ramifications are impossible to predict. Changes within the Eurozone could adversely affect the performance of the SX5E and, consequently, the value of the notes. In addition, you will not obtain the benefit of any increase in the value of the euro against the U.S. dollar which you would have received if you had owned the securities in the SX5E during the term of your notes, although the level of the SX5E may be adversely affected by general exchange rate movements in the market.

§ There may be potential conflicts of interest involving the calculation agent. We have the right to appoint and remove the calculation agent.

§ As a Swiss bank, Credit Suisse is subject to regulation by governmental agencies, supervisory authorities and self-regulatory organizations in Switzerland. Such regulation is increasingly more extensive and complex and subjects Credit Suisse to risks. For example, pursuant to Swiss banking laws, FINMA has broad powers and discretion in the case of resolution proceedings, which include the power to convert debt instruments and other liabilities of Credit Suisse into equity and/or cancel such liabilities in whole or in part.

§ The U.S. federal income tax consequences of the notes are uncertain, and may be adverse to a holder of the notes. See “Material U.S. Federal Income Tax Considerations” below and “Material U.S. Federal Income Tax Considerations” beginning on page PS-29 of product supplement EQUITY INDICES SUN-2.

Other Terms of the Notes

Market Measure Business Day

The provisions of this section supersede and replace the definition of “Market Measure Business Day” set forth in product supplement EQUITY INDICES SUN-2.

A “Market Measure Business Day” means a day on which:

(A) each of the Eurex (as to the EURO STOXX 50^® Index), and the New York Stock Exchange and NASDAQ Stock Market, Inc. (as to the Dow Jones Industrial Average^SM) (or any successor to the foregoing exchanges) are open for trading; and

(B) the Basket Components or any successors thereto are calculated and published.

The Basket

The Basket is designed to allow investors to participate in the percentage changes in the levels of the Basket Components from the Starting Value to the Ending Value of the Basket. The Basket Components are described in the section “The Basket Components” below. Each Basket Component will be assigned an initial weight on the pricing date, as set forth in the table below.

For more information on the calculation of the value of the Basket, please see the section entitled “Description of the Notes – Basket Market Measures” beginning on page PS-23 of product supplement EQUITY INDICES SUN-2.

If July 6, 2015 were the pricing date, for each Basket Component, the Initial Component Weight, the closing level, the hypothetical Component Ratio and the initial contribution to the Basket value would be as follows:

Basket Component	Bloomberg Symbol	Initial Component Weight	Closing Level(1)(2)	Hypothetical Component Ratio(1)(3)	Initial Basket Value Contribution
EURO STOXX 50® Index	SX5E	50.00	3,365.20	0.01485796	50.00
Dow Jones Industrial AverageSM	INDU	50.00	17,683.58	0.00282748	50.00
				Starting Value	100.00

(1) The actual closing level of each Basket Component and the resulting actual Component Ratios will be determined on the pricing date, subject to adjustment as more fully described in the section entitled “Description of the Notes—Basket Market Measures—Determination of the Component Ratio for Each Basket Component” beginning on page PS-23 of product supplement EQUITY INDICES SUN-2 if a Market Disruption Event occurs on the pricing date as to any Basket Component.

(2) These were the closing levels of the Basket Components on July 6, 2015.

(3) Each hypothetical Component Ratio equals the Initial Component Weight of the relevant Basket Component (as a percentage) multiplied by 100, and then divided by the closing level of that Basket Component on July 6, 2015 and rounded to eight decimal places.

The calculation agent will calculate the value of the Basket by summing the products of the closing level for each Basket Component on the calculation day and the Component Ratio applicable to such Basket Component. If a Market Disruption Event occurs as to either Basket Component on the scheduled calculation day, the closing level of that Basket Component will be determined as more fully described beginning on page PS-25 of product supplement EQUITY INDICES SUN-2 in the section “Description of the Notes—Basket Market Measures—Observation Level or Ending Value of the Basket.”

The Basket Components

All disclosures contained in this term sheet regarding the Basket Components, including, without limitation, their make -up, method of calculation, and changes in their components, have been derived from publicly available sources. The information reflects the policies of, and is subject to change by, the index sponsors. The index sponsors, which license the copyright and all other rights to the Basket Components, have no obligation to continue to publish, and may discontinue publication of, the Basket Components. The consequences of the index sponsors discontinuing publication of the Basket Components are discussed in the section entitled “Description of the Notes—Discontinuance of an Index” beginning on page PS-22 of product supplement EQUITY INDICES SUN-2. None of us, the calculation agent, or MLPF&S accepts any responsibility for the calculation, maintenance or publication of the Basket Components or any successor indices.

The EURO STOXX 50^® Index

The EURO STOXX 50^® Index (the “SX5E”) is composed of 50 component stocks of market sector leaders from within the EURO STOXX^® Supersector indices in terms of free float market capitalization, which represent the Eurozone portion of the STOXX Europe 600^® Supersector indices. The STOXX Europe 600^® Supersector indices contain the 600 largest stocks traded on the major exchanges of 18 European countries. The SX5E was created by STOXX Limited, a joint venture between Deutsche Börse AG and SIX Group AG. Publication of the SX5E began on February 26, 1998, based on an initial index level of 1,000 at December 31, 1991. The SX5E is published in The Wall Street Journal and disseminated on the STOXX Limited website, which sets forth, among other things, the country and industrial sector weightings of the securities included in the SX5E, and updates these weightings at the end of each quarter. The SX5E is reported by Bloomberg under the ticker symbol “SX5E.”

On March 1, 2010, STOXX Limited announced the removal of the “Dow Jones” prefix from all of its indices, including the SX5E.

Methodology of the SX5E

The composition of the SX5E is reviewed annually in September, based on the closing stock data on the last trading day in August. The component stocks are announced on the first trading day in September. Changes in the composition of the SX5E are made to ensure that the SX5E includes 50 market sector leaders from within the SX5E. Changes to the component stocks are implemented on the third Friday in September and are effective the following trading day.

The composition of the SX5E is also reviewed monthly to ensure that component stocks still remain eligible for inclusion. The announcement will be on the first trading day of the month after close of the relevant markets. Any resulting changes from the monthly review are implemented on the close of the fifth trading day following the monthly review and are effective the next trading day. All stocks on the latest selection lists and initial public offering (IPO) stocks are reviewed for a fast-track addition on a quarterly basis. The announcement will be on the first trading day of the month after market close. The implementation is effected together with that of the STOXX Total Market Indices. A current list of the issuers that comprise the SX5E is available on the STOXX Limited website. Information contained in the STOXX Limited website is not incorporated by reference in, and should not be considered a part of, this term sheet.

The free float factors for each component stock used to calculate the SX5E, as described below, are reviewed, calculated and implemented on a quarterly basis and are fixed until the next quarterly review. Each component’s weight is capped at 10% of the SX5E’s total free float market capitalization.

The SX5E is also reviewed on an ongoing basis. Corporate actions (including initial public offerings, mergers and takeovers, spin-offs, delistings and bankruptcy) that affect the SX5E composition are immediately reviewed. Any changes are announced, implemented and effective in line with the type of corporate action and the magnitude of the effect.

Computation of the SX5E

The SX5E is calculated with the “Laspeyres formula,” which measures the aggregate price changes in the component stocks against a fixed base quantity weight. The formula for calculating the index value can be expressed as follows:

SX5E =	free float market capitalization of the SX5E
	divisor of the SX5E

The “free float market capitalization of the SX5E” is equal to the sum of the product of the price, number of shares outstanding and free float factor for each component stock as of the time the SX5E is being calculated. The free float factor reduces the number of shares outstanding to the actual amount available on the market. All fractions of the total number of shares that are larger than 5% and whose holding is of a long-term nature are excluded from the index calculation. The free float factor typically excludes cross-ownership (stock owned either by the company itself or other companies), government ownership, private ownership, and restricted shares that cannot be traded during a certain period or have a foreign ownership restriction. Block ownership is not applied for holdings of custodian nominees, trustee companies, mutual funds, investment companies with short-term investment strategies, pension funds and similar entities.

The SX5E is also subject to a divisor, which is adjusted to maintain the continuity of SX5E values despite changes due to corporate actions. All corporate actions and dividends are implemented at the effective date (ex-date); i.e., with corporate actions where cash or other corporate assets are distributed to shareholders, the price of the stock will decrease on the ex-date. The following is a summary of the adjustments to any component stock made for corporate actions and the effect of such adjustment on the divisor, where shareholders of the component stock will receive “B” number of shares for every “A” share held (where applicable). If the new shares

have a dividend disadvantage —i.e., the new shares have a different dividend from that paid on the old shares — the price for these new shares will be adjusted according to the gross dividend amount. The divisor may increase, decrease or be held constant.

DIVISOR:	Decrease	A) Cash dividend (applies to return indices only) adjusted price (net return) = closing price − announced dividend * (1 − withholding tax) adjusted price (gross return) = closing price − announced dividend
DIVISOR:	Decrease	B) Special Cash dividend (applies to price and return indices) adjusted price = closing price − announced dividend * (1 − withholding tax if applicable)
DIVISOR:	Constant	C) Split and Reverse Split adjusted price = closing price * A / B new number of shares = old number of shares * B / A
DIVISOR:	Increase	D) Rights Offering adjusted price = (closing price * A + subscription price * B) / (A + B) new number of shares = old number of shares * (A + B) / A
DIVISOR:	Constant	E) Stock Dividend adjusted price = closing price * A / (A + B) new number of shares = old number of shares * (A + B) / A
	Decrease	F) Stock Dividend (from treasury stock) If treated as regular cash dividend, only the return indices are adjusted. adjusted price = closing price – closing price * B / (A + B) If treated as extraordinary dividend, the price and the return indices are adjusted. adjusted price = closing price – closing price * B / (A + B)
DIVISOR:	Decrease	G) Stock Dividend of a Different Company Security adjusted price = (closing price * A − price of the different company security * B) / A
DIVISOR:	Decrease	H) Return of Capital and Share Consolidation adjusted price = (closing price − capital return announced by company * (1 − withholding tax)) * A / B new number of shares = old number of shares * B / A
DIVISOR:	Decrease	I) Repurchase Shares-Self-Tender adjusted price = ((price before tender * old number of shares) − (tender price * number of tendered shares)) / (old number of shares − number of tendered shares) new number of shares = old number of shares − number of tendered shares
DIVISOR:	Decrease	J) Spinoff adjusted price = (closing price * A − price of spun-off shares * B) / A
DIVISOR:		K) Combination Stock Distribution (Dividend or Split) and Rights Offering Shareholders receive B new shares from the distribution and C new shares from the rights offering for every A shares held:
	Increase	● If rights are applicable after stock distribution (one action applicable to other) adjusted price = [closing price * A + subscription price * C * (1 + B / A)] / [(A + B) * (1 + C / A)] new number of shares = old number of shares * [(A + B) * (1 + C / A)] / A
	Increase	● If stock distribution is applicable after rights (one action applicable to other) adjusted price = [closing price * A + subscription price * C] / [(A + C) * (1 + B / A)] new number of shares = old number of shares * [(A + C) * (1 + B / A)] / A
DIVISOR:	Increase	● Stock distribution and rights (neither action is applicable to the other) adjusted price = [closing price * A + subscription price * C] / [A + B + C] new number of shares = old number of shares * [A + B + C] / A

The Dow Jones Industrial Average^SM

Publication

The Dow Jones Industrial Average^SM (the “INDU”) is a price- weighted index comprised of 30 common stocks selected at the discretion of the editors of The Wall Street Journal, which is published by Dow Jones Indexes, as representative of the broad market of U.S. industry. There are no pre-determined criteria for selection of a component stock, except that component companies represented by the INDU should be established U.S. companies that are leaders in their industries. The INDU serves as a measure of the entire U.S. market, including such sectors as financial services, technology, retail, entertainment and consumer goods, and is not limited to traditionally defined industrial stocks. The INDU is reported by Bloomberg L.P. under the ticker symbol “INDU.”

Methodology of the INDU

The INDU is a price-weighted index, which means an underlying stock’s weight in the INDU is based on its price per share rather than the total market capitalization of the issuer. The INDU is designed to provide an indication of the composite performance of 30 common stocks of corporations representing a broad cross-section of U.S. industry. The corporations represented in the INDU tend to be market leaders in their respective industries and their stocks are typically widely held by individuals and institutional investors.

The INDU is maintained by an Averages Committee comprised of the Managing Editor of The Wall Street Journal, the head of Dow Jones Indexes research and the head of CME Group research. The Averages Committee was created in March 2010, when Dow Jones Indexes became part of CME Group Index Services, LLC, a joint venture company owned 90% by CME Group Inc. and 10% by Dow Jones & Company. Generally, composition changes occur only after mergers, corporate acquisitions or other dramatic shifts in a component's core business. When such an event necessitates that one component be replaced, the entire INDU is reviewed. As a result, when changes are made, they typically involve more than one component. While there are no rules for component selection, a stock typically is added only if it has an excellent reputation, demonstrates sustained growth, is of interest to a large number of investors and accurately represents the sectors covered by the INDU.

Changes in the composition of the INDU are made entirely by the Averages Committee without consultation with the corporations represented in the INDU, any stock exchange or any official agency. Although changes to the common stocks included in the INDU tend to be made infrequently, these stocks may be changed at any time for any reason. The corporations currently represented in the INDU are incorporated in the United States and its territories and their stocks are listed on the New York Stock Exchange and NASDAQ.

The formula used to calculate divisor adjustments is:

New Divisor = Current Divisor    x	Adjusted Sum of Closing Prices
	Unadjusted Sum of Closing Prices

Supplement to the Plan of Distribution

Under our distribution agreement with MLPF&S, MLPF&S will purchase the notes from us as principal at the public offering price indicated on the cover of this term sheet, less the indicated underwriting discount.

We may deliver the notes against payment therefor in New York, New York on a date that is greater than three business days following the pricing date. Under Rule 15c6-1 of the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. Accordingly, if the initial settlement of the notes occurs more than three business days from the pricing date, purchasers who wish to trade the notes more than three business days prior to the original issue date will be required to specify alternative settlement arrangements to prevent a failed settlement.

The notes will not be listed on any securities exchange. In the original offering of the notes, the notes will be sold in minimum investment amounts of 100 units. If you place an order to purchase the notes, you are consenting to MLPF&S acting as a principal in effecting the transaction for your account.

MLPF&S will not receive an underwriting discount for notes sold to certain fee-based trusts and fee-based discretionary accounts managed by U.S. Trust operating through Bank of America, N.A.

MLPF&S has advised us as follows: They or their affiliates may repurchase and resell the notes, with repurchases and resales being made at prices related to then-prevailing market prices or at negotiated prices determined by reference to their pricing models and at their discretion, and these prices will include MLPF&S’s trading commissions and mark-ups. MLPF&S may act as principal or agent in these market-making transactions; however, it is not obligated to engage in any such transactions. MLPF&S has informed us that at MLPF&S’s discretion and for your benefit, assuming no changes in market conditions from the pricing date, MLPF&S may offer to buy the notes in the secondary market at a price that may exceed the initial estimated value of the notes for a short initial period after the issuance of the notes. Any price offered by MLPF&S for the notes will be based on then-prevailing market conditions and other considerations, including the performance of the Basket and the remaining term of the notes. However, none of us, MLPF&S, or any of our respective affiliates is obligated to purchase your notes at any price or at any time, and we cannot assure you that we, MLPF&S, or any of our respective affiliates will purchase your notes at a price that equals or exceeds the initial estimated value of the notes.

MLPF&S has informed us that, as of the date of this term sheet, it expects that if you hold your notes in a MLPF&S account, the value of the notes shown on your account statement will be based on MLPF&S’s estimate of the value of the notes if MLPF&S or another of its affiliates were to make a market in the notes, which it is not obligated to do; and that estimate will be based upon the price that MLPF&S may pay for the notes in light of then-prevailing market conditions and other considerations, as mentioned above, and will include transaction costs. Any such price may be higher than or lower than the initial estimated value of the notes.

The distribution of the Note Prospectus in connection with these offers or sales will be solely for the purpose of providing investors with the description of the terms of the notes that was made available to investors in connection with their initial offering. Secondary market investors should not, and will not be authorized to, rely on the Note Prospectus for information regarding Credit Suisse or for any purpose other than that described in the immediately preceding sentence.

Structuring the Notes

The notes are our debt securities, the return on which is linked to the performance of the Basket. As is the case for all of our debt securities, including our market-linked notes, the economic terms of the notes reflect our actual or perceived creditworthiness at the time of pricing. In addition, because market-linked notes result in increased operational, funding and liability management costs to us, the internal funding rate we use in pricing market-linked notes is typically lower than a rate reflecting the yield on our conventional debt securities of similar maturity in the secondary market. Because we use our internal funding rate to determine the value of the theoretical bond component, if on the pricing date our internal funding rate is lower than our secondary market credit rates, the initial estimated value of the notes will be higher than if the initial estimated value was based our secondary market credit rates.

Payments on the notes, including the amount you receive at maturity, will be calculated based on the $10 principal amount per unit and will depend on the performance of the Basket. In order to meet these payment obligations, at the time we issue the notes, we may choose to enter into certain hedging arrangements (which may include call options, put options or other derivatives) with MLPF&S or one of its affiliates. The terms of these hedging arrangements are determined by seeking bids from market participants, including MLPF&S and its affiliates, and take into account a number of factors, including our creditworthiness, interest rate movements, the volatility of the Basket Components, the tenor of the notes and the tenor of the hedging arrangements. The economic terms of the notes and their initial estimated value depend in part on the terms of these hedging arrangements.

MLPF&S has advised us that the hedging arrangements will include a hedging related charge of approximately $0.075 per unit, reflecting an estimated profit to be credited to MLPF&S from these transactions. Since hedging entails risk and may be influenced by unpredictable market forces, additional profits and losses from these hedging arrangements may be realized by MLPF&S or any third party hedge providers.

Material U.S. Federal Income Tax Considerations

The following discussion is a brief summary of material U.S. federal income tax consequences relating to an investment in the notes. The following summary is not complete and is both qualified and supplemented by, or in some cases supplements, the discussion under the section entitled “Material U.S. Federal Income Tax Considerations” beginning on page PS-29 of product supplement EQUITY INDICES SUN-2, which you should carefully review prior to investing in the notes.

There are no statutory provisions, regulations, published rulings, or judicial decisions addressing the characterization for U.S. federal income tax purposes of the notes or securities with terms that are substantially the same as those of the notes. Thus, the characterization of the notes is not certain. In the absence of an administrative or judicial ruling to the contrary and pursuant to the terms of the notes, you agree with us to treat the notes, for U.S. federal income tax purposes, as prepaid financial contracts, with respect to the Market Measure, that are eligible for open transaction treatment. The balance of this discussion assumes that the notes will be treated as prepaid financial contracts. You should be aware that such characterization of the notes is not certain, nor is it binding on the U.S. Internal Revenue Service (the “IRS”) or the courts. Thus, it is possible that the IRS would seek to characterize your notes in a manner that results in tax consequences to you that are different from those described below or in the accompanying product supplement. We are not responsible for any adverse consequences that you may experience as a result of any alternative characterization of the notes 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 the notes for U.S. federal income tax purposes.

If the notes are treated as prepaid financial contracts, a U.S. Holder (as defined in the accompanying product supplement) should generally recognize gain or loss upon the sale, exchange or maturity of its notes in an amount equal to the difference between the amount realized at such time and the U.S. Holder’s tax basis in its notes (generally the amount paid for the notes). Such gain or loss generally should be long-term capital gain or loss if the notes have been held for more than one year. For notes with a term of one year or less, such gain or loss will be short-term capital gain or loss.

You should consult your tax advisor concerning the U.S. federal income tax and other tax consequences of your investment in the notes in your particular circumstances, including the application of state, local or other tax laws and the possible effects of changes in federal or other tax laws.

Where You Can Find More Information

We have filed a registration statement (including a product supplement, a prospectus supplement, and a prospectus) with the SEC for the offering to which this term sheet relates. Before you invest, you should read the Note Prospectus, including this term sheet, and the other documents that we have filed with the SEC, for more complete information about us and this offering. You may get these documents without cost by visiting EDGAR on the SEC website at www.sec.gov. Alternatively, we, any agent, or any dealer participating in this offering will arrange to send you these documents if you so request by calling MLPF&S toll-free at 1-800-294-1322.
