Hypothetical Redemption Amounts at Maturity for Each $1,000 Principal Amount

The table below illustrates the hypothetical Redemption Amounts at maturity for a $1,000 security for a hypothetical range of performance of the Underlying from +100% to –100%. The hypothetical Redemption Amounts set forth below assume an Initial Level of 135 and an Underlying Return Cap of 18.50% (the midpoint of the expected range set forth on the cover page of this term sheet) and reflect the Upside Participation Rate of 200%. The actual Initial Level and Underlying Return Cap will be determined on the Trade Date. The hypothetical Redemption Amounts set forth below are for illustrative purposes only and may not be the actual returns applicable to a purchaser of the securities. The numbers appearing in the following table and examples have been rounded for ease of analysis.

Hypothetical Examples of Amounts Payable at Maturity

The following examples illustrate how the Redemption Amounts set forth in the table above are calculated.

Example 1: The Final Level is 155.25, an increase of 15% from the Initial Level. The determination of the Redemption Amount when the Final Level is greater than the Initial Level is as follows:

Underlying Return = 200% × [(155.25 – 135)/135] = 30%, subject to an Underlying Return Cap of 18.50%
Underlying Return = 18.50%
Redemption Amount = Principal × (1 + Underlying Return)
Redemption Amount = $1,000 × 1.185
Redemption Amount = $1,185

In this example, at maturity you would be entitled to receive a Redemption Amount equal to $1,185 per $1,000 principal amount of securities based on a leveraged return linked to the appreciation in the level of the Underlying, subject to the Underlying Return Cap.

Example 2: The Final Level is 141.75, an increase of 5.00% from the Initial Level. The determination of the Redemption Amount when the Final Level is greater than the Initial Level is as follows:

Underlying Return = 200% × [(141.75 - 135)/135] = 10%
Redemption Amount = Principal × (1 + Underlying Return)
Redemption Amount = $1,000 × 1.10
Redemption Amount = $1,100

In this example, at maturity you would be entitled to receive a Redemption Amount equal to $1,100 per $1,000 principal amount of securities based on a leveraged return linked to the appreciation in the level of the Underlying.

Example 3: The Final Level is 135, equal to the Initial Level. Because the Final Level is equal to the Initial Level, at maturity you would be entitled to receive a Redemption Amount equal to $1,000 per $1,000 principal amount of securities.

Example 4: The Final Level is 128.25, a decrease of 5% from the Initial Level. Because the Final Level is less than the Initial Level by not more than 10%, at maturity you would be entitled to receive a Redemption Amount equal to $1,000 per $1,000 principal amount of securities.

Example 5: The Final Level is 108, a decrease of 20% from the Initial Level. The determination of the Redemption Amount when the Final Level is less than the Initial Level by more than 10% is as follows:

Underlying Return = [(108 – 135)/135] + 10% = –10%
Redemption Amount = Principal × (1 + Underlying Return)
Redemption Amount = $1,000 × 0.90
Redemption Amount = $900

In this example, at maturity you would be entitled to receive a Redemption Amount equal to $900 per $1,000 principal amount of securities because the Final Level is less than the Initial Level by more than the Buffer Amount and you will participate in any depreciation in the level of the Underlying beyond the Buffer Amount.

Selected Risk Considerations

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

• YOUR INVESTMENT IN THE SECURITIES MAY RESULT IN A LOSS — The securities do not guarantee any return of your principal amount in excess of $100 per $1,000 principal amount. You could lose up to $900 per $1,000 principal amount of securities. If the Final Level is less than the Initial Level by more than 10%, you will lose 1% of your principal for each 1% decline in the Final Level as compared to the Initial Level beyond the Buffer Amount of 10%. Any payment at maturity is subject to our ability to pay our obligations as they become due.

• 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 Underlying, the payment of any amount due on the securities is subject to the credit risk of Credit Suisse. Investors are dependant 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 market value of the securities prior to maturity.

• CAPPED APPRECIATION POTENTIAL — If the Final Level is greater than the Initial Level, for each $1,000 principal amount of securities, you will be entitled to receive at maturity $1,000 multiplied by the sum of 1 plus the Underlying Return, subject to the Underlying Return Cap. The Underlying Return will not exceed the Underlying Return Cap, which is expected to be between 17.00% and 20.00% (to be determined on the Trade Date), regardless of the appreciation in the Underlying, which may be significant. Accordingly, the maximum Redemption Amount of the securities at maturity is expected to be between $1,170 and $1,200 per $1,000 principal amount of securities.

• THE SECURITIES ARE NOT REGULATED BY THE COMMODITY FUTURES TRADING COMMISSION — The proceeds to be received by us from the sale of the securities will not be used to purchase or sell any commodities futures contracts or options on futures contracts for your benefit. An investment in the securities thus does not constitute either an investment in futures contracts, options on futures contracts or in a collective investment vehicle that trades in these futures contracts (i.e., the securities will not constitute a direct or indirect investment by you in the futures contracts), and you will not benefit from the regulatory protections of the Commodity Futures Trading Commission, commonly referred to as the “CFTC.” We are not registered with the CFTC as a futures commission merchant or a commodity pool operator and you will not benefit from the CFTC’s or any other non-U.S. regulatory authority’s regulatory protections afforded to persons who trade in futures contracts on a regulated futures exchange through a registered futures commission merchant or to persons who invest in regulated commodity pools.

• A COMMODITY HEDGING DISRUPTION EVENT MAY RESULT IN ACCELERATION OF THE SECURITIES — If a Commodity Hedging Disruption Event (as defined under “Commodity Hedging Disruption Events” below) occurs, we will have the right, but not the obligation, to accelerate the payment on the securities. The amount due and payable per $1,000 principal amount of securities upon such early acceleration will be determined by the calculation agent in good faith in a commercially reasonable manner on the date on which we deliver notice of such acceleration and will be payable on the fifth business day following the day on which the calculation agent delivers notice of such acceleration.

• COMMODITY FUTURES CONTRACTS ARE SUBJECT TO UNCERTAIN LEGAL AND REGULATORY REGIMES — The commodity futures contracts that comprise the Underlying are subject to legal and regulatory regimes in the United States and, in some cases, in other

4

countries that may change in ways that could adversely affect our ability to hedge our obligations under the securities and affect the value of the Underlying. The Commodity Futures Trading Commission has recently announced that it is considering imposing position limits on certain commodities (such as energy commodities) and the manner in which current exemptions for bona fide hedging transactions or positions are implemented in order to protect against excessive speculation. We or our affiliates may be unable as a result of such restrictions to effect transactions necessary to hedge our obligations under the securities, in which case we may, in our sole and absolute discretion, accelerate the payment on your securities. If the payment on your securities is accelerated, your investment may result in a loss and you may not be able to reinvest your money in a comparable investment. Please see “Commodity Hedging Disruption Events” herein for more information.

• TRADING AND OTHER TRANSACTIONS BY UBS IN THE FUTURES CONTRACTS COMPRISING THE UNDERLYING AND IN THE INDEX COMMODITIES MAY AFFECT THE VALUE OF THE UNDERLYING, AND THERE MAY BE CONFLICTS OF INTEREST BETWEEN YOU AND UBS AND DOW JONES — The Underlying is comprised of futures contracts on nineteen Index Commodities as described below under the heading “The Dow Jones-UBS Commodity Index^SM.” UBS Securities LLC (“UBS”) and its affiliates actively trade futures contracts and options on futures contracts on the Index Commodities (as defined below). UBS and its affiliates also actively enter into or trade and market securities, swaps, options, derivatives, and related instruments that are linked to the performance of commodities or are linked to the performance of the Underlying. Certain affiliates of UBS may underwrite or issue other securities or financial instruments indexed to the Underlying and related indices, and Dow Jones & Company, Inc. (“Dow Jones”), UBS and certain of their affiliates may license the Underlying for publication or for use by unaffiliated third parties. These activities could present conflicts of interest and could affect the value of the Underlying. For instance, a market maker in a financial instrument linked to the performance of the Underlying may expect to hedge some or all of its position in that financial instrument. Purchase (or selling) activity in the components comprising the Underlying in order to hedge the market maker’s position in the financial instrument may affect the market price of the futures contracts included in the Underlying, which in turn may affect the value of the Underlying. With respect to any of the activities described above, none of UBS, Dow Jones or their respective affiliates has any obligation to take the needs of any buyers, sellers or holders of the securities into consideration at any time.

• TRADING AND OTHER TRANSACTIONS BY US OR OUR AFFILIATES IN INDEX COMMODITIES OR FUTURES, OPTIONS, EXCHANGE-TRADED FUNDS OR OTHER DERIVATIVE PRODUCTS ON INDEX COMMODITIES OR THE UNDERLYING MAY IMPAIR THE MARKET VALUE OF THE SECURITIES — We or our affiliates may hedge our respective obligations under the securities by acquiring or disposing of Index Commodities or futures contracts, options, exchange-traded funds or other derivatives or synthetic instruments related to the Index Commodities or the Underlying. Any of these hedging activities may adversely affect the market price of Index Commodities and the level of the Underlying and, therefore, the market value of the securities. It is possible that we or our affiliates could receive substantial returns from these hedging activities while the market value of the securities declines.

• COMMODITY PRICES MAY CHANGE UNPREDICTABLY, AFFECTING THE VALUE OF YOUR SECURITIES IN UNFORESEEABLE WAYS — Trading in futures contracts on physical commodities is speculative and can be extremely volatile. Market prices of the Index Components may fluctuate rapidly based on numerous factors, including: changes in supply and demand relationships (whether actual, perceived, anticipated, unanticipated or unrealized); weather; agriculture; trade; fiscal, monetary and exchange control programs;

5

domestic and foreign political and economic events and policies; disease; pestilence; technological developments; changes in interest rates, whether through governmental action or market movements; and monetary and other governmental policies, action and inaction. The current or “spot” prices of the Index Commodities may also affect, in a volatile and inconsistent manner, the prices of futures contracts in respect of the relevant commodity. These factors may affect the value of the Underlying and the value of your securities in varying ways, and different factors may cause the prices of the futures contracts, and the volatilities of their prices, to move in inconsistent directions at inconsistent rates. The prices of physical commodities, including the Index Commodities, can fluctuate widely due to supply and demand disruptions in major producing or consuming regions. Because certain of the Index Commodities may be produced in a limited number of countries and may be controlled by a small number of producers, political, economic and supply related events in such countries could have a disproportionate impact on the prices of such commodities and the value of your securities.

• YOU WILL NOT HAVE RIGHTS IN THE INDEX COMMODITIES OR THE INDEX COMPONENTS — Investing in the securities will not make you a holder of any of the Index Commodities or any of the Index Components. As an owner of the securities, you will not have rights that investors in the Index Components may have. Your securities will be paid in cash, and you will have no right to receive delivery of any of the Index Components or Index Commodities.

• IF THE INDEX SPONSOR DISCONTINUES OR SUSPENDS THE CALCULATION OF THE UNDERLYING, IT MAY BECOME DIFFICULT TO DETERMINE THE MARKET VALUE OF THE SECURITIES OR THE AMOUNT PAYABLE AT MATURITY — Dow Jones and UBS (together, the “Index Sponsor”) are under no obligation to continue to calculate the Underlying or required to calculate any successor index. If the Index Sponsor discontinues or suspends calculation of the Underlying, it may become difficult to determine the market value of the securities or the amount payable at maturity or upon redemption. The calculation agent may designate a successor index selected in its sole discretion. If the calculation agent determines in its sole discretion that no successor index comparable to the Underlying exists, the amount you receive at maturity or upon redemption will be determined by the calculation agent in the manner described below under “Adjustments to the Calculation of the Underlying.”

• WE AND OUR AFFILIATES HAVE NO AFFILIATION WITH THE INDEX SPONSOR AND ARE NOT RESPONSIBLE FOR ITS PUBLIC DISCLOSURE OF INFORMATION, WHICH MAY CHANGE OVER TIME — We and our affiliates are not affiliated with the Index Sponsor in any way (except for licensing arrangements discussed below under the heading “The Dow Jones-UBS Commodity Index^SM”) and have no ability to control or predict the actions of the Index Sponsor, including any errors in, or discontinuation of disclosure regarding its methods or policies relating to, the calculation of the Underlying in its capacity as Index Sponsor. All disclosure in this term sheet regarding the Underlying, including its make-up, method of calculation and changes in its components, is derived from publicly available information. The information in “The Dow Jones-UBS Commodity Index^SM” section has been taken from (i) publicly available sources and (ii) the Dow Jones-UBS Commodity Index Handbook (a document that is considered proprietary to Dow Jones, UBS and UBS AG and is available to those persons who enter into a license agreement available at http://www.djindexes.com/ubs/index.cfm?go=handbook). Such information is subject to change by the Index Sponsor and we have not independently verified this information. You, as an investor in the securities, should make your own investigation into the Underlying and the Index Sponsor. Reference to the above-mentioned “uniform resource locater” or “URL” is made as an inactive textual reference for informational purposes only. Information found at this web site is not incorporated by reference in, and should not be considered part of, this term sheet.

6

• YOU HAVE NO RECOURSE TO DOW JONES OR UBS — You will have no rights against Dow Jones or UBS as the sponsors of the Underlying. The Index Sponsor is not involved in this offering of the securities in any way and does not have any obligation of any sort with respect to your securities. The Index Sponsor does not have any obligation to take your interests into consideration for any reason, including when taking any actions that might affect the value of your securities. For a more detailed disclaimer by Dow Jones and UBS, see “The Dow Jones-UBS Commodity Index^SM—License Agreement.”

• SUSPENSIONS OR DISRUPTIONS OF MARKET TRADING IN THE COMMODITY MARKETS AND RELATED FUTURES MAY ADVERSELY AFFECT THE VALUE OF THE SECURITIES — The commodity markets are subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets, the participation of speculators and government regulation and intervention. In addition, U.S. futures exchanges and some foreign exchanges have regulations that limit the amount of fluctuation in futures contract prices that may occur during a single business day. These limits are generally referred to as “daily price fluctuation limits” and the maximum or minimum price of a contract on any given day as a result of these limits is referred to as a “limit price.” Once the limit price has been reached in a particular contract, no trades may be made at a different price. Limit prices may have the effect of precluding trading in a particular contract or forcing the liquidation of contracts at disadvantageous times or prices. These circumstances could adversely affect the value of the Underlying and, therefore, the value of the securities.

• INDEX CALCULATION DISRUPTION EVENTS MAY REQUIRE AN ADJUSTMENT TO THE CALCULATION OF THE UNDERLYING — As indicated in the Dow Jones-UBS Commodity Index Handbook, at any time during the term of the securities, the daily calculation of the Underlying may be adjusted in the event that the Index Sponsor determines that any of the following index calculation disruption events exists: the termination or suspension of, or material limitation or disruption in the trading of any futures contract used in the calculation of the Underlying on that day; the settlement price of any futures contract used in the calculation of the Underlying reflects the maximum permitted price change from the previous day’s settlement price; the failure of an exchange to publish official settlement prices for any futures contract used in the calculation of the Underlying or, with respect to any futures contract used in the calculation of the Underlying that trades on the London Metal Exchange (the “LME”), a business day on which the LME is not open for trading. Any such index calculation disruption events may have an adverse impact on the value of the Underlying or the manner in which it is calculated.

• A DESIGNATED CONTRACT MAY BE REPLACED IF THE EXISTING FUTURES CONTRACT IS TERMINATED OR REPLACED — A futures contract known as a “Designated Contract” has been selected as the reference contract for each underlying physical commodity included in the Underlying. Data concerning each Designated Contract will be used to calculate the Underlying. The termination or replacement of a futures contract on an established exchange occurs infrequently; if a Designated Contract were to be terminated or replaced by an exchange, a comparable futures contract would be selected by the Dow Jones-UBS Commodity Index Supervisory and Advisory Committees (prior to January 2007, the Oversight Committee), if available, to replace that Designated Contract. The termination or replacement of any Designated Contract may have an adverse impact on the value of the Underlying. See “The Dow Jones-UBS Commodity Index^SM—Designated Contracts for each Index Commodity.”

• HIGHER FUTURE PRICES OF COMMODITIES INCLUDED IN THE UNDERLYING RELATIVE TO THEIR CURRENT PRICES MAY DECREASE THE REDEMPTION PRICE — As the contracts that comprise the Underlying come to expiration, they are replaced by contracts that have a later expiration. Thus, for example, a contract purchased and held in

7

August may specify an October expiration. As time passes, the contract expiring in October is replaced by a contract for delivery in November. This is accomplished by selling the October contract and purchasing the November contract. This process is referred to as “rolling.” If the market for these contracts is (putting aside other considerations) in “backwardation,” where the prices are lower in the distant delivery months than in the nearer delivery months, the sale of the October contract would take place at a price that is higher than the price of the November contract, thereby creating a “roll yield.” While many of the contracts included in the Underlying have historically exhibited consistent periods of backwardation, backwardation will most likely not exist at all times. Moreover, certain of the commodities included in the Underlying, such as gold, have historically traded in “contango” markets. Contango markets are those in which the prices of contracts are higher in the distant delivery months than in the nearer delivery months. Roll yields are considered in the calculation of the level of the Underlying. The absence of backwardation in the commodity markets could result in negative “roll yields,” which could adversely affect the value of the Underlying and, accordingly, decrease the redemption amount.

• 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 term sheet 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 INTEREST PAYMENTS — As a holder of the securities, you will not receive interest payments.

• 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 easily. 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.

8

• MANY ECONOMIC AND MARKET FACTORS WILL IMPACT THE VALUE OF THE SECURITIES — In addition to the level of the Underlying on any 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:

  • the expected volatility of the Underlying;

  • the time to maturity of the securities;

  • interest and yield rates in the market generally;

  • geopolitical conditions and a variety of economic, financial, political, regulatory or judicial events that affect the commodities comprising the Underlying or commodity markets generally and that may affect the level of the Underlying; and

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

  Some or all of these factors may influence the price that you will receive if you choose to sell your securities prior to maturity. The impact of any of the factors set forth above may enhance or offset some or all of any change resulting from another factor or factors.

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 Underlying and, as a result, could decrease the amount you may receive on the securities at maturity.

The Dow Jones-UBS Commodity Index^SM

We have derived all information regarding the Dow Jones-UBS Commodity Index contained in this term sheet from (i) publicly available sources and (ii) the Dow Jones-UBS Commodity Index Handbook (a document that is considered proprietary to Dow Jones, UBS and UBS AG and is available to those persons who enter into a license agreement available at http://www.djindexes.com/ubs/index.cfm?go=handbook). Such information is subject to change by Dow Jones and UBS. We have not independently verified this information. You, as an investor in the securities, should make your own investigation into the Underlying, Dow Jones and UBS. Neither Dow Jones nor UBS is involved in the offer of the securities in any way and neither has any obligation to consider your interests as a holder of the securities. Reference to the above-mentioned “uniform resource locater” or “URL” is made as an inactive textual reference for informational purposes only. Information found at the web site referenced above is not incorporated by reference in, and should not be considered part of, this term sheet.

The Dow Jones-UBS Commodity Index is a proprietary index that was established in July 1998 to provide a liquid and diversified benchmark for commodities. The Dow Jones-UBS Commodity Index is currently comprised of futures contracts (each, an “Index Component”) on nineteen physical commodities. A commodity futures contract is an agreement that provides for the purchase and sale of a specified type and quantity of a commodity during a stated delivery month for a fixed price. The nineteen commodities for 2009 that comprise the Dow Jones-UBS Commodity Index (the “Index Commodities”) are: aluminum; coffee; copper; corn; cotton; crude oil; gold; heating oil; lean hogs; live cattle; natural gas; nickel; silver; soybeans; soybean oil; sugar; unleaded gasoline; wheat; and zinc. Futures contracts on the Dow Jones-UBS Commodity Index are currently listed for trading on the Chicago Board of Trade (the “CBOT”). The Index Commodities currently trade on United States exchanges, with the exception of aluminum, nickel and zinc, which trade on the London Metal Exchange (the “LME”).

The Dow Jones-UBS Commodity Index tracks what is known as a rolling futures position, which is a position in which, on a periodic basis, futures contracts on physical commodities specifying delivery on a nearby date must be sold and futures contracts on physical commodities with a later delivery date must be purchased. An investor with a rolling futures position is able to avoid delivering underlying physical commodities while maintaining exposure to those commodities. The rollover for each Index Component occurs over a period of five DJ-UBS Business Days each month according to a pre-determined schedule.

The methodology for determining the composition and weighting of the Dow Jones-UBS Commodity Index and for calculating its level is subject to modification by Dow Jones and UBS at any time. Currently, Dow Jones disseminates the Dow Jones-UBS Commodity Index level at approximately 15 second intervals from 8:00 a.m. to 3:00 p.m., New York time, and publishes a daily settlement price for the Dow Jones-UBS Commodity Index at approximately 5:00 p.m., New York time, on each DJ-UBS Business Day on Bloomberg page DJUBS.

A “DJ-UBS Business Day” means a day on which the sum of the Commodity Index Percentages (as described below under “—Annual Reweighting and Rebalancing of the Dow Jones-UBS Commodity Index”) for the Index Commodities that are open for trading is greater than 50%.

The Dow Jones-UBS Commodity Index was created using the following four main principles:

Economic Significance: To achieve a fair representation of a diversified group of commodities to the world economy, the Dow Jones-UBS Commodity Index uses both liquidity data and dollar-weighted production data in determining the relative quantities of included commodities. The Dow Jones-UBS Commodity Index primarily relies on liquidity data, or the relative amount of trading activity of a particular commodity, as an important indicator of the value placed on that commodity by financial and physical market participants. The Dow Jones-UBS Commodity Index also relies on production data as a useful measure of the importance of a commodity to the world economy.

Diversification: In order to avoid the Dow Jones-UBS Commodity Index being subjected to microeconomic shocks in one commodity or sector, diversification rules have been established and are applied annually on a price-percentage basis in order to maintain diversified commodities exposure over time.

Continuity: The Dow Jones-UBS Commodity Index is intended to provide a stable benchmark so that there is confidence that historical performance data is based on a structure that bears some resemblance to both the current and future composition of the Dow Jones-UBS Commodity Index.

Liquidity: The inclusion of liquidity as a weighting factor helps to ensure that the Dow Jones-UBS Commodity Index can accommodate substantial investment flows.

Designated Contracts for each Index Commodity

A futures contract known as a Designated Contract is selected for each of the 23 commodities eligible for inclusion in the Dow Jones-UBS Commodity Index. If more than one such contract exists, the Index Sponsor will select the most actively traded contract. Data concerning this Designated Contract will be used to calculate the Dow Jones-UBS Commodity Index. The termination or replacement of a futures contract on an established exchange occurs infrequently; if a Designated Contract were to be terminated or replaced, a comparable futures contract would be selected, if available, to replace that Designated Contract. The Designated Contracts for the 19 commodities currently included in the Dow Jones-UBS Commodity Index are as follows:

Commodity	Current Weighting of
Price Quote	Designated Contract(1)	Exchange
Natural Gas	7.28%		NYMEX

Annual Reweighting and Rebalancing of the Dow Jones-UBS Commodity Index

The Dow Jones-UBS Commodity Index is reweighted and rebalanced each year in January on a price-percentage basis. The annual weightings for the Dow Jones-UBS Commodity Index are determined each year in June or July. The annual weightings are announced in July and implemented the following January.

12

The relative weightings of the component commodities included in the Dow Jones-UBS Commodity Index are determined annually according to both liquidity and dollar-adjusted production data in two-thirds and one-third shares, respectively. Each June, for each commodity designated for potential inclusion in the Dow Jones-UBS Commodity Index, liquidity is measured by the commodity liquidity percentage (the “CLP”) and production by the commodity production percentage (the “CPP”). The CLP for each commodity is determined by taking a five-year average of the product of the trading volume and the historic value of the Designated Contract for that commodity, and dividing the result by the sum of the products for all commodities that were designated for potential inclusion in the Dow Jones-UBS Commodity Index. The CPP is determined for each commodity by taking a five-year average of annual world production figures, adjusted by the historic value of the Designated Contract, and dividing the result by the sum of the production figures for all the commodities that were designated for potential inclusion in the Dow Jones-UBS Commodity Index. The CLP and CPP are then combined (using a ratio of 2:1) to establish the Commodity Index Percentage (the “CIP”) for each commodity. The CIP is then adjusted in accordance with the diversification rules described below in order to determine the commodities that will be included in the Dow Jones-UBS Commodity Index and their respective percentage weights.

To ensure that no single commodity or commodity sector dominates the Dow Jones-UBS Commodity Index, the following diversification rules are applied to the annual reweighting and rebalancing of the Dow Jones-UBS Commodity Index as of January of the applicable year:

• No related group of commodities designated as a Commodity Group (e.g., energy, precious metals, livestock or grains) may constitute more than 33% of the Dow Jones-UBS Commodity Index;

• No single commodity may constitute more than 15% of the Dow Jones-UBS Commodity Index;

• No single commodity, together with its derivatives (e.g., crude oil, together with heating oil and unleaded gasoline), may constitute more than 25% of the Dow Jones-UBS Commodity Index; and

• No single commodity may constitute less than 2% of the Dow Jones-UBS Commodity Index.

Following the annual reweighting and rebalancing of the Dow Jones-UBS Commodity Index in January, the percentage of any single commodity or group of commodities at any time prior to the next reweighting or rebalancing will fluctuate and may exceed or be less than the percentages set forth above.

13

Following application of the diversification rules discussed above, the CIPs are incorporated into the Dow Jones-UBS Commodity Index by calculating the new unit weights for each Index Commodity. Near the beginning of each new calendar year, the CIPs, along with the settlement prices on that date for the Index Components, are used to determine the commodity index multiplier (the “CIM”) for each Index Commodity. The CIM is used to achieve the percentage weightings of the Index Commodities, in dollar terms, indicated by their respective CIPs. After the CIMs are calculated, they remain fixed throughout the year. As a result, the observed price percentage of each Index Commodity will float throughout the year, until the CIMs are reset the following year based on new CIPs. The CIM for each of the Index Commodities included in the Dow Jones-UBS Commodity Index for 2009 are as follows:

The Dow Jones-UBS	2009 Commodity Index
Commodity Index Commodity	Multiplier (“CIM”)
Natural Gas	52.957386400
Crude Oil	7.592336320
Unleaded Gasoline (RBOB)	86.611391080
Heating Oil	61.493914290
Live Cattle	130.707755740
Lean Hogs	98.757229960
Wheat	20.461483020
Corn	35.938858790
Soybeans	20.082708710
Soybean Oil	208.464754610
Aluminum	0.115420380
Copper	126.467801040
Zinc	0.063917040
Nickel	0.006139090
Gold	0.244395540
Silver	6.811632160
Sugar	653.655142790
Cotton	119.454917530
Coffee	68.100845940

Computation of the Dow Jones-UBS Commodity Index

The Dow Jones-UBS Commodity Index is calculated by Dow Jones, in conjunction with UBS, by applying the impact of the changes to the prices of the Index Components (based on their relative weightings). Once the CIMs are determined as discussed above, the calculation of the Dow Jones-UBS Commodity Index is a mathematical process whereby the CIMs for the Index Components are multiplied by the prices for the Index Components. These products are then summed. The percentage change in this sum is then applied to the prior level of the Dow Jones-UBS Commodity Index to calculate the current level of the Dow Jones-UBS Commodity Index level.

Market Disruption Events

A “Market Disruption Event” is the occurrence on any date or any number of consecutive dates of any one or more of the following circumstances: (a) a termination or suspension of, or a material limitation or disruption for at least two hours in trading in one or more Index Components that prevents the relevant exchange on which such Index Component is traded from establishing an official settlement price for such contract as of the regularly scheduled time; (b) the settlement price for any Index Components is a “limit price,” which means that the settlement price for such contract for a day has increased or decreased from the previous day’s settlement price by the maximum amount permitted under applicable exchange rules; (c) failure by the applicable exchange or other price source to announce or publish the settlement price for any Index Components; and (d) failure of the Index Sponsor to publish the value of the Underlying, subject to certain adjustments below.

If the calculation agent determines that a Market Disruption Event exists with respect to an Index Component on the Valuation Date, then the calculation agent will determine a Special Ending Price and use this Special Ending Price when calculating the Final Level of the Underlying. A Special Ending Price will be determined in the following manner: the official settlement price for any Index Component that experienced a Market Disruption Event on the Valuation Date will be the official settlement price for the first subsequent underlying business day upon which no Market Disruption Event occurs, and for any Index Component that does not experience a Market Disruption Event on the Valuation Date, the official settlement price for such Index Component as published by the relevant exchange on the Valuation Date, in each case, will be incorporated into the Special Ending Price. If the calculation agent determines that a Market Disruption Event exists with respect to an Index Component on each of the five underlying business days immediately following the Valuation Date, (a) the fifth succeeding underlying business day after the original Valuation Date will be deemed to be the Valuation Date for such Index Component, notwithstanding the Market Disruption Event, and (b) the calculation agent will determine the settlement price for such Index Component on that deemed Valuation Date using its good faith estimate of the settlement price for such Index Component that would have prevailed on the applicable exchange but for the suspension or limitation, as of the valuation time on the deemed Valuation Date. As a result of the foregoing, a Special Ending Price may differ substantially from the level of the Underlying that would have been obtained in the absence of a Market Disruption Event.

If the calculation agent determines that a Market Disruption Event exists in respect to the Underlying (but not in respect of any Index Component) on the Valuation Date, then the calculation agent will determine the level of the Underlying using the official settlement prices on the Valuation Date on the relevant exchanges of each Index Component included in the Underlying as of the valuation time on the Valuation Date.

16

In the event that a Market Disruption Event exists with respect to an Index Component on the Valuation Date, the Maturity Date of the securities will be the third business day following the day as of which the Final Level has been calculated. No interest or other payment will be payable because of any such postponement of the Maturity Date.

Adjustments to the Calculation of the Underlying

If the Underlying is not calculated by the Index Sponsor and announced by Dow Jones but (a) is calculated and announced by a successor or successors acceptable to the calculation agent or (b) replaced by a successor index using, in the determination of the calculation agent, the same or a substantially similar formula for and method of calculation as used in the calculation of the Underlying, then the Underlying will be deemed to be the index so calculated and announced by such successor sponsor or sponsors or such successor index, as the case may be.

Upon any selection by the calculation agent of a successor index, the calculation agent will cause notice to be furnished to us and the trustee, which will provide notice of the selection of the successor index to the registered holders of the securities in the manner set forth below.

If (x) on or prior to the Valuation Date, Dow Jones and UBS make, in the determination of the calculation agent, a material change in the formula for or the method of calculating the Underlying or in any other way materially modify the Underlying or (y) on the Valuation Date, Dow Jones and UBS (or a successor sponsor or sponsors) fail to calculate and announce the Underlying and there is no comparable index available, then the calculation agent will calculate the Redemption Amount using, in lieu of a published level for the Underlying, the level for the Underlying as at the valuation time on the Valuation Date as determined by the calculation agent in accordance with the formula for and method of calculating the Underlying last in effect prior to that change or failure, but using only those commodity futures contracts that comprised the Underlying immediately prior to that change or failure. Notice of adjustment of the Underlying will be provided by the trustee in the manner set forth below.

All determinations made by the calculation agent will be at the sole discretion of the calculation agent and will be conclusive for all purposes and binding on us and the beneficial owners of the securities, absent manifest error.

Commodity Hedging Disruption Events

If a Commodity Hedging Disruption Event (as defined below) occurs, we will have the right, but not the obligation, to accelerate the payment on the securities by providing, or causing the calculation agent to provide, written notice of our election to exercise such right to the trustee at its New York office, on which notice the trustee may conclusively rely, as promptly as possible and in no event later than the business day immediately following the day on which such Commodity Hedging Disruption Event occurred. The amount due and payable per $1,000 principal amount of securities upon such early acceleration will be determined by the calculation agent in good faith in a commercially reasonable manner on the date on which we deliver notice of such acceleration and will be payable on the fifth business day following the day on which the calculation agent delivers notice of such acceleration. We will provide, or will cause the calculation agent to provide, written notice to the trustee at its New York office, on which notice the trustee may conclusively rely, and to the Depository Trust Company (“DTC”) of the cash amount due with respect to the securities as promptly as possible and in no event later than two business days prior to the date on which such payment is due. For the avoidance of doubt, the determination set forth above is only applicable to the amount due with respect to acceleration as a result of a Commodity Hedging Disruption Event.

17

A “Commodity Hedging Disruption Event” means that:

(a)

due to (i) the adoption of, or any change in, any applicable law, regulation or rule or (ii) the promulgation of, or any change in, the interpretation by any court, tribunal or regulatory authority with competent jurisdiction of any applicable law, rule, regulation or order (including, without limitation, as implemented by the CFTC or any exchange or trading facility), in each case occurring on or after the Trade Date, the calculation agent determines in good faith that it is contrary to such law, rule, regulation or order to purchase, sell, enter into, maintain, hold, acquire or dispose of our or our affiliates’ (A) positions or contracts in securities, options, futures, derivatives or foreign exchange or (B) other instruments or arrangements, in each case, in order to hedge individually or in the aggregate on a portfolio basis our obligations under the securities (“hedge positions”), including, without limitation, if such hedge positions are (or, but for the consequent disposal thereof, would otherwise be) in excess of any allowable position limit(s) in relation to any commodity traded on any exchange(s) or other trading facility (it being within the sole and absolute discretion of the calculation agent to determine which of the hedge positions are counted towards such limit); or

(b)

for any reason, we or our affiliates are unable, after using commercially reasonable efforts, to (i) acquire, establish, re-establish, substitute, maintain, unwind or dispose of any transaction(s) or asset(s) the calculation agent deems necessary to hedge the risk of entering into and performing our commodity-related obligations with respect to the securities, or (ii) realize, recover or remit the proceeds of any such transaction(s) or asset(s).

Commodity Futures Markets

Futures contracts on physical commodities and commodity indices are traded on regulated futures exchanges, and physical commodities and other derivatives on physical commodities and commodity indices are traded in the over-the-counter market and on various types of physical and electronic trading facilities and markets. At present, all of the contracts included in the Underlying are exchange-traded futures contracts. An exchange-traded futures contract provides for the purchase and sale of a specified type and quantity of a commodity or financial instrument during a stated delivery month for a fixed price. A futures contract on an index of commodities provides for the payment and receipt of cash based on the level of the index at settlement or liquidation of the contract. A futures contract provides for a specified settlement month in which the cash settlement is made or in which the commodity or financial instrument is to be delivered by the seller (whose position is therefore described as “short”) and acquired by the purchaser (whose position is therefore described as “long”).

There is no purchase price paid or received on the purchase or sale of a futures contract. Instead, an amount of cash or cash equivalents must be deposited with the broker as “initial margin.” This amount varies based on the requirements imposed by the exchange clearing houses, but may be lower than 5% of the value of the contract. This margin deposit provides collateral for the obligations of the parties to the futures contract.

By depositing margin, which may vary in form depending on the exchange, with the clearing house or broker involved, a market participant may be able to earn interest on its margin funds, thereby increasing the total return that it may realize from an investment in futures contracts. The market participant normally makes to, and receives from, the broker subsequent daily payments as the price of the futures contract fluctuates. These payments are called “variation margin” and are made as the existing positions in the futures contract become more or less valuable, a process known as “marking to the market.”

Futures contracts are traded on organized exchanges, known as “contract markets” in the United States. At any time prior to the expiration of a futures contract, subject to the availability of a liquid secondary market, a trader may elect to close out its position by taking an opposite position on the exchange on which the trader obtained the position. This operates to terminate the position and fix the

18

trader’s profit or loss. Futures contracts are cleared through the facilities of a centralized clearing house and a brokerage firm, referred to as a “futures commission merchant,” which is a member of the clearing house. The clearing house guarantees the performance of each clearing member that is a party to a futures contract by, in effect, taking the opposite side of the transaction. Clearing houses do not guarantee the performance by clearing members of their obligations to their customers.

Unlike equity securities, futures contracts, by their terms, have stated expirations and, at a specified point in time prior to expiration, trading in a futures contract for the current delivery month will cease. As a result, a market participant wishing to maintain its exposure to a futures contract on a particular commodity with the nearest expiration must close out its position in the expiring contract and establish a new position in the contract for the next delivery month, a process referred to as “rolling.” For example, a market participant with a long position in November crude oil futures that wishes to maintain a position in the nearest delivery month will, as the November contract nears expiration, sell November futures, which serves to close out the existing long position, and buy December futures. This will “roll” the November position into a December position, and, when the November contract expires, the market participant will still have a long position in the nearest delivery month.

Historical Information

The following graph sets forth the historical performance of the Dow Jones-UBS Commodity Index based on the closing levels of the Underlying from January 1, 2004 through December 28, 2009. The closing level of the Underlying on December 28, 2009 was 140.0458. 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.

The historical levels of the Underlying should not be taken as an indication of future performance, and no assurance can be given as to the closing level of the Underlying on any trading day during the term of the securities, including on the Valuation Date. We cannot give you assurance that the performance of the Underlying will result in any return of your investment beyond the Buffer Amount.

Certain United States Federal Income Tax Considerations

The following discussion summarizes certain 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.

20

Characterization of the Securities

There are no 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, we intend to treat the securities, for U.S. federal income tax purposes, as a prepaid financial contract, with respect to the Underlying that is eligible for open transaction treatment. In the absence of an administrative or judicial ruling to the contrary, we and, by acceptance of the securities, you, agree to treat your securities for all tax purposes in accordance with such characterization. In light of the fact that we agree to treat the securities as a prepaid financial contract, the balance of this discussion assumes that the securities will be so treated.

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 the securities 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 and they had term of more than one year, 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. 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 debt instruments or contingent payment debt instruments.

It is also possible that the IRS would 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. 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 adviser 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

21

partnership. If you are a partnership, or a partner of a partnership, holding securities, you should consult your tax adviser 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, upon receipt of the redemption amount of the securities from us, a U.S. Holder will recognize gain or loss equal to the difference between the amount of cash received from us and the U.S. Holder’s tax basis in the security at that time. For securities with a term of more than one year, such gain or loss will be long-term capital gain or loss if the U.S. Holder has held the security for more than one year at maturity. For securities with a term of one year or less, such gain or loss will be short-term capital gain or loss.

Upon the sale or other taxable disposition of a security, a U.S. Holder generally will recognize capital gain or loss equal to the difference between the amount realized on the sale or other taxable disposition and the U.S. Holder’s tax basis in the security (generally its cost). For securities with a term of more than one year, such gain or loss will be long-term capital gain or loss if the U.S. Holder has held the security for more than one year at the time of disposition. For securities with a term of one year or less, such gain or loss will be short-term capital gain or loss.

Non-U.S. Holders Generally

In the case of a holder of the securities that is not a U.S. Holder and has no connection with the United States other than holding its securities (a “Non-U.S. Holder”), payments made with respect to the securities 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 will generally not be subject to U.S. federal income tax unless (i) such gain is effectively connected with a U.S. trade or business of such Non-U.S. Holder or (ii) 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.

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.

     Possible Legislation Affecting Securities Held Through Foreign Accounts

On December 7, 2009, the Tax Extenders Act of 2009 (the “Act”) was introduced in the U.S. Congress. The Act would impose a 30% withholding tax on “withholdable payments” made to foreign financial institutions (and their 50% affiliates) unless the payee foreign financial institution agrees 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 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, as well as gross proceeds from the sale of any property of a type which can produce interest or dividends from sources within the United States. The Act also requires withholding agents making withholdable payments to certain foreign entities that do not disclose the taxpayer identification number of any substantial U.S. owners to withhold tax at a rate of 30%.

Withholding under the Act would apply to all withholdable 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 would 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. Generally, the Act’s withholding and reporting regime is proposed

22

to apply to payments made after December 31, 2012. Thus, if you hold your securities through a foreign financial institution or foreign corporation or trust, a portion of your gains may be subject to 30% withholding if the Act is enacted, payment is made after December 31, 2012.

     Possible Legislation Affecting Dividend Equivalent Payments

The Act also treats 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 would be subject to U.S. withholding tax. A "dividend equivalent" payment is (i) a substitute dividend payment, (ii) a payment made pursuant to a notional principal contract that 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). These changes would apply to payments made on or after the date that is 90 days after the date on which the Act is enacted. Where the securities reference an interest in securities or an index that may provide for the payment of dividends from sources within the United States, absent guidance from the IRS, it is uncertain whether the IRS would determine payments under the securities to be substantially similar to a dividend. Thus, if the IRS determines that a payment is substantially similar to a dividend, it may be subject to U.S. withholding tax, unless reduced by an applicable tax treaty, if the Act is enacted.

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 advisers 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 (a) the appropriate method for accruing income or expense (e.g., a mark-to-market methodology or a method resembling the noncontingent bond method), (b) whether income and gain on such an instrument should be ordinary or capital, and (c) whether foreign holders should be subject to withholding tax on any deemed income accrual.

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 adviser regarding Notice 2008-2 and its possible impact on you.

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 information reporting requirements and 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.
