General

•

The securities are designed for investors who are bearish, neutral or mildly bullish on the Underlyings. Investors should be willing to lose some or all of their investment if the closing level of either Underlying reaches or exceeds the Knock-In Level for that Underlying on any trading day from but excluding the Trade Date to and including the Valuation Date. Any payment on the securities is subject to our ability to pay our obligations as they become due.

•

Interest will be paid in arrears at a rate expected to be between 8.00% and 10.00% per annum (to be determined on the Trade Date). Interest will be calculated on a 30/360 basis, subject to Early Redemption.

•

The Issuer may redeem the securities, in whole but not in part, on any Interest Payment Date on or after November 1, 2010. No interest will accrue or be payable following an Early Redemption.

•

Senior unsecured obligations of Credit Suisse AG, acting through its Nassau Branch, maturing August 1, 2011.†

Key Terms

Issuer:	Credit Suisse AG ("Credit Suisse"), acting through its Nassau Branch
Underlyings:	Each Underlying is identified in the table below, together with its Bloomberg ticker symbol, Initial Level and Knock-In Level:
	Underlying				Ticker	Initial Level	Knock-In Level
	S&P 500 Index ("SPX")				SPX
	Russell 2000 Index ("RTY")				RTY
Interest Rate:	Expected to be between 8.00% and 10.00% per annum (to be determined on the Trade Date). Interest will be calculated on a 30/360 basis.
Interest Payment Dates:	Unless redeemed earlier, interest will be paid in arrears on November 1, 2010, February 1, 2011, May 1, 2011 and the Maturity Date, subject to the modified following business day convention. No interest will accrue or be payable following an Early Redemption.
Redemption Amount:	The Redemption Amount you will be entitled to receive will depend on the individual performance of each Underlying and whether a Knock-In Event occurs. If the securities are not subject to Early Redemption, the Redemption Amount will be determined as follows:
	•	If a Knock-In Event occurs during the Observation Period, the Redemption Amount will equal the principal amount of the securities you hold multiplied by the difference of one minus the Underlying Return of the Better Performing Underlying. In this case, the maximum Redemption Amount will equal the principal amount of the securities. Therefore, unless the Final Level of each of the Underlyings is less than or equal to its Initial Level, the Redemption Amount will be less than the principal amount of the securities and you could lose your entire investment.
	•	If a Knock-In Event does not occur during the Observation Period, the Redemption Amount will equal the principal amount of the securities you hold.
	Any payment you will be entitled to receive at maturity is subject to our ability to pay our obligations as they become due.
Early Redemption:	The Issuer may redeem the securities in whole, but not in part, on any Interest Payment Date occurring on or after November 1, 2010 upon at least five business days notice at 100% of the principal amount of the securities, together with the interest payable on that Interest Payment Date.
Knock-In Event:	A Knock-In Event occurs if the closing level of either Underlying reaches or exceeds the Knock-In Level for that Underlying on any trading day during the Observation Period.
Knock-In Level:	The Knock-In Level for each Underlying will be 122.50% of the Initial Level of such Underlying.
Better Performing Underlying:	The Underlying with the higher Underlying Return.
Underlying Return:	For each Underlying, the Underlying Return will be calculated as follows using the Initial Level and the Final Level of such Underlying:
			Final Level – Initial Level Initial Level	; subject to a minimum of zero
Initial Level:	For each Underlying, the closing level of such Underlying on the Trade Date.
Final Level:	For each Underlying, the closing level of such Underlying on the Valuation Date.
Observation Period:	The period from but excluding the Trade Date to and including the Valuation Date.
Valuation Date:†	July 27, 2011
Maturity Date:†	August 1, 2011
Listing:	The securities will not be listed on any securities exchange.
CUSIP:	22546EXK5

† Subject to postponement if the scheduled Maturity Date is not a business day or the scheduled Valuation Date is not an underlying business day and in the event of a market disruption event as described in the accompanying product supplement under "Description of the Securities—Market disruption events."

Hypothetical Redemption Amounts and Total Payments on the Securities

The tables and examples below illustrate hypothetical Redemption Amounts payable at maturity and, in the case of the tables, total payments over the term of the securities (which include both payments at maturity and the total interest paid on the securities) on a $1,000 investment in the securities for a range of Underlying Returns of the Better Performing Underlying, both in the event a Knock-In Event does not occur and in the event a Knock-In Event does occur. The tables and examples assume that (i) the securities are not redeemed prior to maturity, (ii) the Interest Rate applicable to the securities is 9.00% per annum (the midpoint of the expected range set forth on the cover page of this term sheet), (iii) the term of the securities is exactly one year and (iv) the Knock-In Level for each Underlying is 122.50% of the Initial Level of such Underlying. In addition, the examples below assume that the Initial Level is 1100 for SPX and 650 for RTY. The examples are intended to illustrate hypothetical calculations of only the Redemption Amount and total payment amount and do not illustrate the calculation or payment of any individual interest payment. The Redemption Amounts and total payment amounts set forth below are provided for illustration purposes only. The actual Redemption Amounts and total payments applicable to a purchaser of the securities will depend on several variables, including, but not limited to (a) whether the closing level of either Underlying is greater than or equal to its respective Knock-In Level on any trading day during the Observation Period and (b) the Final Level of the Better Performing Underlying determined on the Valuation Date. It is not possible to predict whether a Knock-In Event will occur, and in the event that there is a Knock-In Event, whether and by how much the Final Level of the Better Performing Underlying will increase in comparison to its Initial Level. Any payment you will be entitled to receive is subject to our ability to pay our obligations as they become due. The numbers appearing in the following tables and examples have been rounded for ease of analysis.

TABLE 1:    A Knock-In Event DOES NOT occur during the Observation Period.

Principal Amount of Securities	Percentage Change from the Initial Level to the Final Level of the Better Performing Underlying	Underlying Return of the Better Performing Underlying	Redemption Amount (Knock-In Event does not occur)	Total Interest Payment on the Securities	Total Payment on the Securities

$1,000	-50%	0%	$1,000	$90	$1,090

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

Underlying	Initial Level	Highest closing level of the Underlying during the Observation Period	Final Level on the Valuation Date
SPX	1100	1650 (150% of Initial Level)	1650 (150% of Initial Level)
RTY	650	780 (120% of Initial Level)	780 (120% of Initial Level)

Since the closing level of SPX exceeds its Knock-In Level during the Observation Period, a Knock-In Event occurs. SPX is also the Better Performing Underlying.

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

Final Level of SPX - Initial Level of SPX
Initial Level of SPX ; subject to a minimum of zero

= (1650 - 1100) / 1100 = 0.50

Redemption Amount (per $1000 principal amount securities)
	=	$1,000 × (1 - Underlying Return of the Better Performing Underlying)
	=	$1,000 × (1 - 0.50)
	=	$500

3

Example 2: A Knock-In Event occurs because the closing level of one Underlying reaches its Knock-In Level during the Observation Period; the Better Performing Underlying never reaches or exceeds its Knock-In Level during the Observation Period; and the Final Level of the Better Performing Underlying is greater than its Initial Level.

Underlying	Initial Level	Highest closing level of the Underlying during the Observation Period	Final Level on the Valuation Date
SPX	1100	1347.50 (122.50% of Initial Level)	1210 (110% of Initial Level)
RTY	650	780 (120% of Initial Level)	780 (120% of Initial Level)

Since the closing level of SPX reaches its Knock-In Level during the Observation Period, a Knock-In Event occurs. RTY is the Better Performing Underlying, even though its closing level never reaches or exceeds its Knock-In Level during the Observation Period.

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

Final Level of RTY - Initial Level of RTY
Initial Level of RTY ; subject to a minimum of zero

= (780 - 650) / 650 = 0.20

Redemption Amount (per $1000 principal amount securities)
	=	$1,000 × (1 - Underlying Return of the Better Performing Underlying)
	=	$1,000 × (1 - 0.20)
	=	$800

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

Underlying	Initial Level	Highest closing level of the Underlying during the Observation Period	Final Level on the Valuation Date
SPX	1100	1347.50 (122.50% of Initial Level)	1045 (95% of Initial Level)
RTY	650	780 (120% of Initial Level)	585 (90% of Initial Level)

Since the closing level of SPX reaches its Knock-In Level, a Knock-In Event occurs. SPX is also the Better Performing Underlying.

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

Final Level of SPX - Initial Level of SPX
Initial Level of SPX ; subject to a minimum of zero

= (1045 - 1100) / 1100 = -0.05

BUT - -0.05 is less than the minimum of zero, so the Underlying Return of the Better Performing Underlying is zero.

Redemption Amount (per $1000 principal amount securities)
	=	$1,000 × (1 - Underlying Return of the Better Performing Underlying)
	=	$1,000 × (1 - 0.00)
	=	$1,000

4

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

Underlying	Initial Level	Highest closing level of the Underlying during the Observation Period	Final Level on the Valuation Date
SPX	1100	1210 (110% of Initial Level)	1045 (95% of Initial Level)
RTY	650	650 (100% of Initial Level)	585 (90% of Initial Level)

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

Therefore, the Redemption Amount equals $1,000.

Selected Risk Considerations

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

•

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



•

THE SECURITIES WILL NOT PAY MORE THAN THE PRINCIPAL AMOUNT, PLUS ACCRUED AND UNPAID INTEREST, AT MATURITY OR UPON EARLY REDEMPTION – The securities will not pay more than the principal amount, plus accrued and unpaid interest, at maturity or upon early redemption. If the Final Level of each Underlying is less than its respective Initial Level (regardless of whether a Knock-In Event has occurred), you will not receive more than the principal amount of your securities at maturity, excluding interest. Assuming the securities are held to maturity and the term of the securities is exactly 1 year, the maximum amount payable with respect to the securities is expected to be between $1,080 and $1,100 (to be determined on the Trade Date) for each $1,000 principal amount of securities.



•

THE SECURITIES ARE SUBJECT TO THE CREDIT RISK OF CREDIT SUISSE – Although the return on the securities will be based on the performance of the Underlyings, the payment of any amount due on the securities, including any applicable interest payments, early redemption payment or payment at maturity, is subject to the credit risk of Credit Suisse. Investors are 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 value of the securities prior to maturity.

5

•

THE REDEMPTION AMOUNT PAYABLE AT MATURITY WILL BE LESS THAN THE PRINCIPAL AMOUNT OF THE SECURITIES EVEN IF A KNOCK-IN EVENT OCCURS WITH RESPECT TO ONLY ONE UNDERLYING AND THE FINAL LEVEL OF ONLY ONE UNDERLYING IS GREATER THAN ITS INITIAL LEVEL – Even if the closing level of only one Underlying reaches or exceeds its Knock-In Level on any trading day during the Observation Period, a Knock-In Event will have occurred. In this case, the Redemption Amount payable at maturity will be less than the principal amount of the securities if, in addition to the occurrence of a Knock-In Event, the Final Level of just one Underlying is greater than its Initial Level. This will be true even if the closing level of the Better Performing Underlying never reached or increased above its Knock-In Level on any trading day during the Observation Period.



•

THE SECURITIES ARE SUBJECT TO A POTENTIAL EARLY REDEMPTION, WHICH WOULD LIMIT YOUR ABILITY TO ACCRUE INTEREST OVER THE FULL TERM OF THE SECURITIES – The securities are subject to a potential early redemption. The securities may be redeemed on any Interest Payment Date occurring on or after November 1, 2010 upon at least five business days notice. If the securities are redeemed prior to the Maturity Date, you will be entitled to receive the principal amount of your securities and any accrued but unpaid interest payable on such Interest Payment Date. In this case, you will lose the opportunity to continue to accrue and be paid interest from the Early Redemption Date to the scheduled Maturity Date. If the securities are redeemed prior to the Maturity Date, you may be unable to invest in other securities with a similar level of risk that yield as much interest as the securities.



•

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

6

•

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.



•

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



•

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



•

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



o

the expected volatility of the Underlyings;



o

the time to maturity of the securities;



o

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



o

interest and yield rates in the market generally;



o

investors' expectations with respect to the rate of inflation;



o

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



o

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

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

7

•

NO OWNERSHIP RIGHTS RELATING TO THE EQUITY SECURITIES COMPRISING THE UNDERLYINGS – Your return on the securities will not reflect the return you would realize if you actually owned the equity securities that comprise the Underlyings. The return on your investment, which is based on the percentage change in the Underlyings, is not the same as the total return based on the purchase of shares of the equity securities that comprise the Underlyings.



•

NO DIVIDEND PAYMENTS OR VOTING RIGHTS – As a holder of the securities, you will not have voting rights or rights to receive cash dividends or other distributions or other rights with respect to the equity securities that comprise the Underlyings.

Use of Proceeds and Hedging

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

Historical Information

The following graphs set forth the historical performance of the Underlyings based on their closing levels from January 1, 2005 through July 14, 2010. The closing level of the S&P 500 Index on July 14, 2010 was 1095.17. The closing level of the Russell 2000 Index on July 14, 2010 was 640.16. We obtained the closing levels of the Underlyings from Bloomberg, without independent verification. We make no representation or warranty as to the accuracy or completeness of the information obtained from Bloomberg. You should not take the historical levels of the Underlyings as an indication of future performance of the Underlyings or the securities. The levels of either of the Underlyings may increase so that a Knock-In Event occurs and at maturity you will receive a Redemption Amount equal to less than the principal amount of your securities. Any payment on the securities is subject to our ability to pay our obligations as they become due. We cannot give you any assurance that the closing levels of the Underlyings will remain below their respective Knock-In Levels during the Observation Period. If the closing level of either Underlying reaches or exceeds its Knock-In Level on any trading day during the Observation Period, and the closing level of the Better Performing Underlying on the Valuation Date is less than its Initial Level, you will lose money on your investment.

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.

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. Under one approach, each security is treated, for U.S. federal income tax purposes,

10

as (1) a call option (the "Call Option") that requires the holder to cash settle against the value of the best performing Underlying for an amount equal to the Deposit (as defined below) if any Underlying appreciates to a defined ceiling level and the final level thereof is equal to or greater than the initial level, and (2) a deposit with us of cash, in an amount equal to the amount paid for a security (the "Deposit") to secure the holder's potential obligation to cash settle against the value of the best performing Underlying. We intend to treat the securities consistent with this approach. In the absence of an administrative or judicial ruling to the contrary, we and, by acceptance of a security, each holder agree to treat the securities as consisting of a Deposit and a Call Option with respect to the value of the best performing Underlying for all U.S. federal income tax purposes. 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.

Alternatively, in the event that the securities have a term of more than one year and reference an equity interest in a "pass-thru entity" within the meaning of Code section 1260 (which includes shares in, among others, an exchange-traded fund, a regulated investment company, a real estate investment trust, a partnership or trust), the IRS might assert that the securities constitute a "constructive ownership transaction." If the securities were treated as a constructive ownership transaction, under Code section 1260, all or a portion of your gain, if any, from the securities would be recharacterized as ordinary income, and you would be required to pay additional tax calculated by reference to interest on the tax on such recharacterized income. We are not responsible for any adverse consequences that you may experience as a result of any alternative characterization of the securities for U.S. federal income tax or other tax purposes.

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

U.S. Holders

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

Interest Payments on the Securities

In accordance with the agreed-upon tax treatment described above, the portion of each coupon payment on the security that should be treated as interest on the Deposit is 1.24063% per annum and the balance should be treated as call premium received by the U.S. Holder in respect of the Call Option to us (the "Call Premium").

We will treat the Deposit as a debt obligation issued by us. Accordingly, we will treat each coupon payment as consisting of interest of 1.24063% per annum on the Deposit and the balance as Call Premium paid to you. U.S. Holders should therefore include such interest component of the coupon in income as received or accrued, based on their method of accounting.

Call Premium and Payment of Redemption Amount on the Securities

A U.S. Holder should not be subject to tax upon receipt of the Call Premium.

If a knock-in event has occurred, a U.S. Holder should recognize short-term capital gain or loss equal to the difference between (1) the cash proceeds so received (other than in respect of any accrued but unpaid coupon on the security, which will be taxed as described above under "—Interest Payments on the Securities") plus the Call Premium, and (2) the U.S. Holder's tax basis in the security (generally equal to the amount of the Deposit).

If a knock-in event has not occurred, a U.S. Holder will receive cash equal the principal amount of the security and should recognize short-term capital gain or loss equal to the difference between (1) the cash proceeds so received (other than in respect of any accrued but unpaid coupon on the security, which will be taxed as described above under "—Interest Payments on the Securities") and (2) the U.S. Holder's tax basis in the security. This difference is expected to equal zero. The Call Option should be deemed to have expired unexercised and the Call Premium received should be treated as short-term capital gain at such time.

Sale or Exchange of the Securities

Upon a sale or exchange of a security, a U.S. Holder should allocate the sale proceeds received between the Deposit and the Call Option on the basis of their respective fair market values on the date of sale. The U.S. Holder should generally recognize gain or loss with respect to the Deposit in an amount equal to the difference between the amount of the sale proceeds allocable to the Deposit and the U.S. Holder's adjusted tax basis in the Deposit (which will generally equal the issue

12

price of the security). Except to the extent attributable to accrued but unpaid interest with respect to the Deposit, which will be subject to tax as described above under "—Interest Payments on the Securities," such gain or loss should be long-term capital gain or loss for securities with a term of more than one year, 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. A U.S. Holder should recognize short-term capital gain equal to the amount of remaining sale proceeds allocable to the Call Option plus any previously received Call Premium. If the value of the Deposit exceeds the total sale proceeds received, then the U.S. Holder should be treated as having paid the buyer an amount equal to the amount of such excess in exchange for the buyer's assumption of the U.S. Holder's rights and obligations under the Call Option (such excess being referred to as "Deemed Payment"). In such a case, the U.S. Holder should recognize short-term capital gain or loss in an amount equal to the difference between the total Call Premium previously received, if any, and the amount of the Deemed Payment made by the U.S. Holder to the buyer with respect to the assumption of the Call Option. The amount of the Deemed Payment should be added to the sale proceeds allocated to the Deposit in determining the gain or loss in respect of the Deposit.

Legislation Affecting Securities Held Through Foreign Accounts

Congress recently enacted the "Hiring Incentives to Restore Employment Act" (the "Act"). Under the Act, a 30% withholding tax is imposed on "withholdable payments" made to foreign financial institutions (and their more than 50% affiliates) unless the payee foreign financial institution agrees, among other things, to disclose the identity of any U.S. individual with an account at the institution (or the institution's affiliates) and to annually report certain information about such account. "Withholdable payments" include 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 name, address, and taxpayer identification number of any substantial U.S. owners (or to certify that they do not have any substantial United States owners) to withhold tax at a rate of 30%. We will treat payments on the securities as withholdable payments for these purposes.

Withholding under the Act 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 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 any of your payments made after December 31, 2012 may be subject to 30% withholding.

Non-U.S. Holders Generally

The U.S. withholding tax consequences of any coupon payment in respect of the securities is uncertain. Given the uncertainty, we will withhold U.S. income tax at a rate of 30% on any coupon payment. It may be possible for a non-U.S. Holder (a "Non-U.S. Holder") to take the position that some or all of a coupon payment is exempt from the 30% U.S. withholding tax or subject to a reduced withholding tax rate under an applicable tax treaty. Any Non-U.S. Holder taking the position that a coupon payment is exempt from the 30% withholding tax or eligible for a reduced rate of U.S. withholding tax may seek a refund or credit of any excess amounts withheld by us by filing an appropriate claim for refund with the IRS.

In the case of a holder of the securities that is not a U.S. Holder and has no connection with the United States other than holding its securities, payment of the redemption amount by us in 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 (1) such gain is effectively connected with a U.S. trade or business of such Non-U.S. Holder or (2) in the case of an individual, such individual is present in the United States for 183 days or more in the taxable year of the sale or other disposition and certain other conditions are met.

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.

Legislation Affecting Substitute Dividend and Dividend Equivalent Payments

The Act 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 made pursuant to a securities lending or a sale-repurchase transaction that (directly or indirectly) is contingent upon, or determined by reference to, the payment of a dividend from sources within the United States, (ii) a payment made pursuant to a "specified notional principal contract" that (directly or indirectly) is contingent upon, or determined by reference to, the payment of a dividend from sources within the United States, and (iii) any other payment determined by the IRS to be substantially similar to a payment described in the preceding clauses (i) and (ii). These changes will apply to payments made on or after September 14, 2010. In the case of payments made after March 18, 2012, a dividend equivalent payment includes a payment made pursuant to any notional principal contract unless otherwise exempted by the IRS. Where the securities reference an interest in a fixed basket of securities or an index, such fixed basket or index will be treated as a single security. Where the securities reference an interest in a basket of 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 that payments under the securities are substantially similar to a dividend. 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.

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

14

should consult their tax advisors regarding the U.S. federal estate tax consequences of holding the securities at death.

IRS Notice on Certain Financial Transactions

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

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

Information Reporting Regarding Specified Foreign Financial Assets

The Act also requires individual U.S. Holders with an interest in any "specified foreign financial asset" to file a report to the IRS with information relating to the asset and the maximum value thereof during the taxable for any year in which the aggregate value of all such assets is greater than $50,000 (or such higher dollar amount as prescribed by Treasury regulations). Specified foreign financial assets include any depository or custodial account held at a foreign financial institution; any debt or equity interest in a foreign financial institution if such interest is not regularly traded on an established securities market; and, if not held at a financial institution, (i) any stock or security issued by a non-United States person, (ii) any financial instrument or contract held for investment where the issuer or counterparty is a non-United States person, and (iii) any interest in an entity which is a non-United States person. Depending on the aggregate value of your investment in specified foreign financial assets, you may be obligated to file an annual report under this provision. The requirement to file a report is effective for taxable years beginning after March 18, 2010. Penalties apply to any failure to file a required report. Additionally, in the event a U.S. Holder does not file the information report relating to disclosure of specified foreign financial assets, the statute of limitations on the assessment and collection of U.S. federal income taxes of such U.S. Holder for the related tax year will not close before such information is filed. You should consult your own tax advisor as to the possible application to you of this information reporting requirement and related statute of limitations tolling provision.

Backup Withholding and Information Reporting

A holder of the securities (whether a U.S. Holder or a Non-U.S. Holder) may be subject to 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.
