Autocallable Market-Linked Step Up Notes

Linked to the S&P Oil & Gas Exploration & Production Select Industry Index, due September 22, 2017

Summary

The Autocallable Market-Linked Step Up Notes Linked to the S&P Oil & Gas Exploration & Production Select Industry Index, due September 22, 2017 (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 will be automatically called at the Call Amount if the Observation Level of the Market Measure, which is the S&P Oil & Gas Exploration & Production Select Industry Index (the “Index”), is equal to or greater than the Call Level on the Observation Date. If not called, at maturity, the notes provide you with a Step Up Payment if the Ending Value of the Index 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 level of the Index above the Starting Value. If the Ending Value is less than the Starting Value, you will lose all or a portion of the principal amount of your notes. Payments on the notes, including the amount you receive at maturity or upon an automatic call, will be calculated based on the $10 principal amount per unit and will depend on the performance of the Index, subject to our credit risk. See “Terms of the Notes” below.

The economic terms of the notes (including the Call Premium and the Call Amount) 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, reduced 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 is greater than the initial estimated value of the notes.

On the cover page of this term sheet, we have provided the initial estimated value for the notes. This estimated value 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 used to determine the estimated value of the notes. The notes are subject to an automatic call, and the initial estimated value is based on an assumed tenor of the notes. For more information about the initial estimated value and the structuring of the notes, see “Structuring the Notes” on page TS-14.

Hypothetical Payout Profile at Maturity

The below graph is based on hypothetical numbers and values. These hypothetical values show a payout profile at maturity, which would only apply if the notes are not called on the Observation Date.

Market-Linked Step Up Notes     This graph reflects the returns on the notes based on the Threshold Value of 100% of the Starting Value, the Step Up Payment of $3.00 per unit and the Step Up Value of 130% of the Starting Value. 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 Index, 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, assuming the notes are not called on the Observation Date. The actual amount you receive and the resulting total rate of return will depend on the actual Starting Value, Threshold Value, Ending Value, Step Up Value, whether the notes are called on the Observation Date, and term of your investment.

The following table is based on a Starting Value of 100, a Threshold Value of 100, a Step Up Value of 130 and the Step Up Payment of $3.00 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
0.00	-100.00%	$0.00	-100.00%
50.00	-50.00%	$5.00	-50.00%

150.00	50.00%	$15.00	50.00%
160.00	60.00%	$16.00	60.00%

(1) The hypothetical Starting Value of 100 used in these examples has been chosen for illustrative purposes only. The actual Starting Value is 5,157.43, which was the closing level of the Market Measure on the pricing date.

(2) This is the hypothetical Threshold Value.

(3) This amount represents the sum of the principal amount and the Step Up Payment of $3.00.

(4) This is the hypothetical Step Up Value.

For recent actual levels of the Market Measure, see “The Index” section below. The Index 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 the Index, 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.

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.

§ If the notes are not automatically called, depending on the performance of the Index 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.

§ If the notes are called, your investment return is limited to the return represented by the Call Premium.

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

§ 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-13. 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 exceeds 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-13.

§ 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-13. 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 level of the Index, 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 Index), 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.

§ The Index sponsor may adjust the Index in a way that affects its level, and has no obligation to consider your interests.

§ You will have no rights of a holder of the securities represented by the Index, 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 Index, we, MLPF&S and our respective affiliates do not control any company included in the Index, and are not responsible for any disclosure made by any other company.

§ 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.

Additional Risk Factors

The stocks included in the Index are concentrated in one sector.

All of the stocks included in the Index are issued by companies in the oil and gas exploration and production sector. As a result, the stocks that will determine the performance of the notes are concentrated in one sector. Although an investment in the notes will not give holders any ownership or other direct interests in the stocks underlying the Index, the return on an investment in the notes will be subject to certain risks associated with a direct equity investment in companies in this sector, including those discussed below. Accordingly, by investing in the notes, you will not benefit from the diversification which could result from an investment linked to companies that operate in multiple sectors.

The stocks of companies in the oil and gas sector are subject to swift price fluctuations.

The issuers of the stocks included in the Index develop and produce, among other things, crude oil and natural gas, and provide, among other things, drilling services and other services related to oil and gas production and distribution. Stock prices for these types of companies are affected by supply and demand both for their specific product or service and for oil and gas products in general. The price of oil and gas, exploration and production spending, government regulation, world events and economic conditions will likewise affect the performance of these companies. Correspondingly, the stocks of companies in this sector are subject to swift price fluctuations caused by events relating to international politics, energy conservation, the success of exploration projects and tax and other governmental regulatory policies. Weak demand for the companies’ products or services or for oil and gas products and services in general, as well as negative developments in these other areas, would adversely impact the value of the stocks included in the Index and, therefore, the level of the Index and the value of the notes.

The Index

All disclosures contained in this term sheet regarding the Index, including, without limitation, its make-up, method of calculation, and changes in its components, have been derived from publicly available sources. The information reflects the policies of, and is subject to change by, S&P Dow Jones Indices LLC (the “Index sponsor”). The Index sponsor, which licenses the copyright and all other rights to the Index, has no obligation to continue to publish, and may discontinue publication of, the Index. The consequences of the Index sponsor discontinuing publication of the Index 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 Index or any successor index.

The Index

The Index is an equally-weighted index that is designed to measure the performance of the oil and gas exploration and production sub-industry portion of the S&P Total Market Index (“S&P TMI”), an index that measures the performance of the U.S. equity market. The S&P TMI includes all U.S. common equities listed on the NYSE (including NYSE Arca), the NYSE MKT, the NASDAQ Global Select Market, and the NASDAQ Capital Market. Each of the component stocks in the Index is a constituent company within the oil and gas sub-industry portion of the S&P TMI.

To be eligible for inclusion in the Index, companies must be in the S&P TMI, and must be included in the relevant Global Industry Classification Standard (GICS) sub-industry. The GICS was developed to establish a global standard for categorizing companies into sectors and industries. In addition, companies must satisfy one of the two following combined size and liquidity criteria:

1. float-adjusted market capitalization above US$500 million and float-adjusted liquidity ratio above 90%; or

2. float-adjusted market capitalization above US$400 million and float-adjusted liquidity ratio above 150%.

All U.S. companies satisfying these requirements are included in the Index. The total number of companies in the Index should be at least 35. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds above are included in order of their float-adjusted market capitalization to reach 35 constituents. Minimum market capitalization requirements may be relaxed to ensure there are at least 22 companies in the Index as of each rebalancing effective date.

Eligibility factors include:

Market Capitalization: Float-adjusted market capitalization should be at least US$400 million for inclusion in the Index. Existing index components must have a float-adjusted market capitalization of US$300 million to remain in the Index at each rebalancing.

Liquidity: The liquidity measurement used is a liquidity ratio, defined as dollar value traded over the previous 12-months divided by the float-adjusted market capitalization as of the Index rebalancing reference date. Stocks having a float-adjusted market capitalization above US$500 million must have a liquidity ratio greater than 90% to be eligible for addition to the Index. Stocks having a float-adjusted market capitalization between US$400 and US$500 million must have a liquidity ratio greater than 150% to be eligible for addition to the Index. Existing index constituents must have a liquidity ratio greater than 50% to remain in the Index at the quarterly rebalancing. The length of time to evaluate liquidity is reduced to the available trading period for IPOs or spin-offs that do not have 12 months of trading history.

Domicile: U.S. companies only.

Takeover Restrictions: At the discretion of the Index sponsor, constituents with shareholder ownership restrictions defined in company organizational documents may be deemed ineligible for inclusion in the Index. Ownership restrictions preventing entities from replicating the index weight of a company may be excluded from the eligible universe or removed from the Index.

Turnover: At times a company may appear to temporarily violate one or more of the addition criteria. However, the addition criteria are for addition to the Index, not for continued membership. As a result, an index constituent that appears to violate the criteria for addition to the Index will not be deleted unless ongoing conditions warrant a change in the composition of the Index.

Computation of the Index

The Index is equally-weighted, with adjustments to constituent weights to ensure concentration and liquidity requirements, and calculated by the divisor methodology used in all of the Index sponsor’s equity indices.

The initial divisor is set to have a base index value of 1,000 on December 17, 1999. The index value is calculated as the index market value divided by the index divisor:

Index Value = Index Market Value / Divisor

In order to maintain index series continuity, the divisor is also adjusted at each rebalancing.

(Index Value) before rebalancing = (Index Value) after rebalancing

Therefore,

Autocallable Market-Linked Step Up Notes  TS-10

Autocallable Market-Linked Step Up Notes

Linked to the S&P Oil & Gas Exploration & Production Select Industry Index, due September 22, 2017

(Divisor) after rebalancing = (Index Market Value) after rebalancing/ (Index Value) before rebalancing

At each quarterly rebalancing, the stocks underlying the Index are initially equally-weighted using closing prices as of the second Friday of the last month of the quarter as the reference price. Adjustments are then made to ensure that there are no stocks whose weight in the Index is more than can be traded in a single day for a US$ 500 million portfolio.

The Index sponsor calculates a maximum basket liquidity weight for each stock in the Index using the ratio of its three-month average daily value traded to US$500 million. Each stock’s weight in the Index is then compared to its maximum basket liquidity weight and is set to the lesser of its maximum basket liquidity weight or its initial equal weight. All excess weight is redistributed across the Index to the uncapped component stocks.

If necessary, a final adjustment is made to ensure that no stock in the Index has a weight greater that 4.5%. This step of the iterative weighting process may force the weight of those stocks limited to their maximum basket liquidity weight to exceed that weight. In such cases, the Index sponsor will make no further adjustments. If the Index contains exactly 22 companies as of the rebalancing effective date, the Index will be equally weighted without basket liquidity constraints.

Index Maintenance

Index maintenance will follow that of the S&P TMI. The membership of the Index is reviewed quarterly. Rebalancing occurs after the closing on the third Friday of the quarter ending month. The reference date for additions and deletions is after the closing of the last trading date of the previous month. However, a company will be deleted from the Index if the S&P TMI drops the constituent. Unless a constituent deletion causes the number of companies in the Index to fall below 22, no addition will be made to the Index until the next rebalancing. At that time, the entire Index will be rebalanced based on all eligibility criteria, including the minimum number of companies. If a constituent deletion causes the number of companies in the Index to fall below 22, an addition is made assuming the weight of the dropped stock. When a stock is removed from the Index at a price of $0.00, the stock’s replacement will be added to the Index at the weight using the previous day’s closing value, or the most immediate prior business day that the deleted stock was not valued at $0.00. No Index adjustment will be made when there are share changes between quarterly share adjustments. In case of GICS changes, where a company does not belong to the oil and gas exploration and production sub-industry after the classification change, it is removed from the Index at the next rebalancing.

The treatment of corporate actions is the same as in the S&P TMI. In case of a spin-off, generally both the parent company and spin-off companies will remain in the Index until the next rebalancing, regardless of whether they conform to the theme of the Index. When there is no market-determined price available for the spin-off company, the spin-off company is added to the Index at zero price at the close of the day before the ex-date. In the case of a rights offering, the price is adjusted to the price of the parent company minus (the price of the rights subscription/rights ratio). The Index Shares change so that the company’s weight remains the same as its weight before the spin-off. In case of stock dividend, stock split or reverse stock split, the Index Shares are multiplied by and price is divided by the split factor. Share issuance, share repurchase, equity offering or warrant conversion will not cause an Index adjustment. When special dividends are paid, the price of the stock making the special dividend payment is reduced by the per share special dividend amount after the close of trading on the day before the dividend ex-date.

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 will 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, 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 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 Index 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 Index. 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 or upon an automatic call, will be calculated based on the $10 principal amount per unit and will depend on the performance of the Index. 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 Index, 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 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.

However, even if the agreed-upon tax characterization of the notes were upheld, it is possible that the IRS could assert that a reconstitution or rebalancing (together, a “Rebalancing”) of the Market Measure is a significant modification of the notes due to an exercise of discretion with respect to the Rebalancing and, therefore, a taxable event to you. If the IRS were to prevail in treating any Rebalancing of the Market Measure as a taxable event, you would recognize capital gain or, possibly, loss on the notes on the date of such Rebalancing to the extent of the difference between the fair market value of the notes and your adjusted basis in the notes at that time. Such gain or loss generally would 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.
