Reverse Convertible Securities
Linked to the Common Stock of a Reference Share Issuer
or the Shares of an Exchange Traded Fund

The securities offered by this product supplement, which we refer to as the "securities," will be linked to the performance of the equity securities (the "reference shares") of an issuer (each, a "reference share issuer") or the shares of an exchange traded fund (the "fund shares"). The term "equity securities" includes non-U.S securities issued through depositary arrangements such as American depositary shares or American depositary receipts (together, "ADSs"). If a reference share is an ADS, the term "reference share issuer" shall refer to the issuer of the equity securities underlying such ADS. If specified in the applicable pricing supplement, the securities may be Select Method Reverse Convertible Securities or Z Series Reverse Convertible Securities, as described in this product supplement.

This product supplement describes terms that will apply generally to the securities and supplements the terms described in the accompanying prospectus supplement and prospectus. A separate term sheet or pricing supplement, as the case may be, will describe terms that apply specifically to the securities, including any changes to the terms specified in this product supplement. We refer to such term sheets and pricing supplements generally as pricing supplements. If the terms described in the applicable pricing supplement are inconsistent with those described herein or in the accompanying prospectus supplement or prospectus, the terms described in the applicable pricing supplement will control.

The reference shares or fund shares to which the securities will be linked will be specified in the applicable pricing supplement. The maturity date of the securities will be specified in the applicable pricing supplement, subject to postponement if a market disruption event occurs on the valuation date.

The securities will bear interest at the rate per annum specified in the applicable pricing supplement. Interest payments will be made to you on the interest payment dates specified in the applicable pricing supplement, subject to the modified following business day convention, as described herein, unless otherwise specified in the applicable pricing supplement.

The redemption amount of the securities at maturity will be based upon the performance of the reference shares or fund shares specified in the applicable pricing supplement during the term of the securities and whether a knock-in event (as defined below) has occurred.

Unless otherwise specified in the applicable pricing supplement, the redemption amount will be calculated as follows:

The physical delivery amount will be the number of reference shares, rounded down to the nearest whole number, per $1,000 principal amount of securities equal to the product of (i) $1,000 divided by the initial share price and (ii) the share adjustment factor, plus the cash value of any fractional share amount. The market value of the physical delivery amount, if any, or the cash value thereof, will be less than the principal amount of your securities and may be zero.

Any payment you will be entitled to receive at maturity is subject to our ability to pay our obligations as they become due.

Unless otherwise specified in the applicable pricing supplement, a "knock-in event" will occur with respect to the relevant reference shares or fund shares, as applicable, if, in the case of closing price monitoring, the closing price of the relevant reference shares or fund shares, as applicable, reaches or falls below its knock-in level on any trading day during the observation period or in the case of continuous monitoring, if the price of the relevant reference shares or fund shares, as applicable, reaches or falls below its knock-in level at any time on any trading day during the observation period, as applicable. The applicable pricing supplement may specify a different type of monitoring during the observation period for the relevant reference shares or fund shares, as applicable. In addition, the applicable pricing supplement may specify that a knock-in event will occur with respect to the relevant reference shares or fund shares, as applicable, if the closing price or the price of such reference shares or fund shares, as applicable, only falls below its knock-in level, rather than reaches or falls below its knock-in level on any trading day or at any time during the observation period, as applicable.

The "initial share price," "final share price," "observation period" and "knock-in level" will be specified in the applicable pricing supplement.

Please refer to "Risk Factors" beginning on page PS-3 of this product supplement for risks related to an investment in the securities.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this product supplement or the prospectus supplement or the prospectus to which it relates is truthful or complete. Any representation to the contrary is a criminal offense.

What are the Reverse Convertible Securities and how is the redemption amount calculated?

The Reverse Convertible Securities, or the securities, are medium-term notes issued by us, the return on which is linked to the performance of the reference shares or fund shares specified in the applicable pricing supplement. At maturity you will be entitled to receive a redemption amount, if any, that will depend on the performance of the relevant reference shares or fund shares, as applicable, and on whether a knock-in event has occurred.

For a description of how the redemption amount will be calculated, please refer to "Description of the Securities—Redemption amount" herein.

An investment in the securities involves risks. Please see the "Risk Factors" section beginning on page PS-3.

An investment in the securities is not principal protected. In addition, any payment you will be entitled to receive at maturity is subject to our ability to pay our obligations as they become due.

Unless otherwise specified in the applicable pricing supplement, we will pay interest at a rate per annum specified in the applicable pricing supplement, from and including the issue date to and including the maturity date, regardless of whether a knock-in event occurs.

Will I receive any dividend payments on, or have shareholder rights in, the reference shares or fund shares underlying the securities?

As a holder of the securities, you will not receive any dividend payments or other distributions on the reference shares or fund shares underlying the securities or have voting or any other rights of a holder of such shares.

Unless otherwise specified in the applicable pricing supplement, the securities will not be listed on any securities exchange. Accordingly, there is no assurance that a liquid trading market will develop for the securities. Credit Suisse Securities (USA) LLC ("CSSU") currently intends to make a market in the securities, although it is not required to do so and may stop making a market at any time.

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.

What are the United States federal income tax consequences of investing in the securities?

Please refer to "Certain United States Federal Income Tax Considerations" herein for a discussion of certain United States federal income tax considerations for making an investment in the securities.

A purchase of the securities involves risks. This section describes significant risks relating to the securities. You should read the following information about these risks, together with the other information contained in or incorporated by reference in the relevant pricing supplement, underlying supplement, if applicable, this product supplement and the accompanying prospectus supplement and prospectus, before investing in the securities.

An investment in the securities is not principal protected and 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 share price of the relevant reference shares or fund shares, as applicable, is less than the initial share price, you will be entitled to receive either the physical delivery amount or, at our sole discretion, the cash value thereof. In this case, the redemption amount you will be entitled to receive will be less than the principal amount of your securities. The return on the securities will be fully exposed to any depreciation in the reference shares or fund shares, as applicable and you could lose your entire investment if the price of the relevant reference shares or fund shares, as applicable, falls to zero. 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

The securities will not pay more than the principal amount, plus accrued and unpaid interest, at maturity. Even if the final share price of the relevant reference shares or fund shares, as applicable, is greater than the initial share price (regardless of whether a knock-in event has occurred), you will not receive the appreciation of any such reference shares or fund shares, as applicable.

The yield on the securities may be lower than the return on an ordinary debt security with similar maturity

We will pay interest on the securities at the rate specified in the applicable pricing supplement. This interest rate may be lower than the rate you could receive on ordinary interest-bearing debt securities with similar maturities, including other of our debt securities. The return payable on each security may not be enough to compensate you for any loss in value due to inflation and other factors relating to the value of money over time.

The cash value of the reference shares or fund shares, as applicable, may not correspond to the market value of such shares on the maturity date

You will be entitled to receive the redemption amount of the securities on the maturity date. If a knock-in event occurs during the observation period and the final share price of the relevant reference shares or fund shares, as applicable, is less than the initial share price, the redemption amount will consist of either the physical delivery amount or, at our sole discretion, the cash value thereof.

If you receive the physical delivery amount, the market price of the shares you receive could decline between the valuation date and the maturity date which is when you will actually receive such shares. Similarly, if we elect to deliver the cash value of the physical delivery amount, we will determine such cash value on the valuation date and you will not benefit from any appreciation in the market price of the reference shares or fund shares, as applicable, that may occur between the valuation date and the maturity date.

Although the return on the securities will be based on the performance of the relevant reference shares or fund shares, as applicable, the payment of any amount due on the securities, including any applicable interest payments, payment at maturity or physical delivery amount, is subject to the credit risk of Credit Suisse. Investors are dependant on Credit Suisse's 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.

If the applicable pricing supplement specifies that the relevant reference shares or fund shares, as applicable, are subject to continuous monitoring, it is possible that a knock-in event could occur under circumstances that would not result in the occurrence of a knock-in event if such reference shares or fund shares, as applicable were instead subject to closing price monitoring

The relevant reference shares or fund shares, as applicable, will be subject to continuous monitoring or closing price monitoring, or, if so specified in the applicable pricing supplement, another method for monitoring such reference shares or fund shares, as applicable. If the relevant reference shares or fund shares, as applicable, are subject to continuous monitoring, a knock-in event will occur if the price of such reference shares or fund shares, as applicable, reaches or falls below the knock-in level at any time on any trading day during the observation period, even if such reference shares or fund shares, as applicable, close above the knock-in level on that trading day. However, if such reference shares or fund shares, as applicable, were instead subject to closing price monitoring, a knock-in event would not occur if the price of such reference shares or fund shares, as applicable, reached or fell below the knock-in level at any time on any trading day during the observation period but closed above the knock-in level on every trading day during the observation period.

The applicable pricing supplement may specify a different type of monitoring during the observation period for the relevant reference shares or fund shares, as applicable. In addition, the pricing supplement may specify that a knock-in event will occur with respect to the relevant reference shares or fund shares, as applicable, if the price of such reference shares or fund shares, as applicable, only falls below its knock-in level, rather than reaches or falls below its knock-in level.

The final share price for the relevant reference shares or fund shares, as applicable may be less than the closing price of such reference shares or fund shares during the term of the securities

If a knock-in event has occurred during the observation period, but the final share price is greater than or equal to the initial share price, you will be entitled to receive a cash payment equal to 100% of the principal amount of your securities at maturity. If a knock-in event has occurred during the observation period and the final share price is less than the initial share price, you will be entitled to receive the physical delivery amount or, at our sole discretion, the cash value thereof. Because the final share price for the relevant reference shares or fund shares, as applicable, is calculated based on the closing price of such reference shares or fund shares, as applicable, on the valuation date or dates, the closing price of such reference shares or fund shares, as applicable, at other times during the term of the securities, including dates near the valuation date or dates, could be higher than the final share price for such reference shares or fund shares, as applicable. This difference could be substantial if there is a significant decrease in the closing price of the relevant reference shares or fund shares, as applicable, around the time of the valuation date or dates or if there is significant volatility in the closing price of such reference shares or fund shares, as applicable, during the term of the securities (especially on dates near the valuation date or dates). For example, when the valuation date for the relevant reference shares or fund shares, as applicable, is near the end of the term of the securities, then if the closing price for such reference shares or fund shares, as applicable, increases or remains relatively constant during the initial term of the securities and then decreases below the initial share

price, the final share price may be significantly less than if it were calculated on a date earlier than the valuation date. In this case, if you receive the physical delivery amount (or, at our sole discretion, the cash value thereof) at maturity, the market value of such amount will be less than the principal amount of your securities and may be zero.

The price at which you will be able to sell your securities to us or our affiliates prior to maturity, if at all, may be at a substantial discount from the principal amount, even in cases where the relevant reference shares or fund shares, as applicable, have appreciated during the term of the securities. The potential returns described in the applicable pricing supplement assume that your securities, which are not designed to be short-term trading instruments, are held to maturity. You should be willing and able to hold your securities to maturity.

No ownership rights relating to the relevant reference shares or fund shares

Your return on the securities will not reflect the return you would realize if you actually owned the relevant reference shares or fund shares, as applicable. Therefore, the return on your investment, which is based on the percentage change in the relevant reference shares or fund shares, as applicable, is not the same as the total return based on the purchase of the reference shares or fund shares, as applicable. As an investor in the securities, you will not have voting rights, rights to receive dividends or other distributions or any other rights with respect to the reference shares or the fund shares, as applicable.

Unless otherwise specified in the applicable pricing supplement, the securities will not be listed on any securities exchange. There may be little or no secondary market for the securities. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the securities easily or at a price advantageous to you. CSSU currently intends to make a market in the securities, although it is not required to do so and may stop making a market at any time. 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.

You will have no rights against any reference share issuer. The securities are not sponsored, endorsed, sold or promoted by any reference share issuer. No reference share issuer has passed on the legality or suitability of, or the accuracy or adequacy of descriptions and disclosures relating to, the securities. No reference share issuer makes any representation or warranty, express or implied, to you or any member of the public regarding the advisability of investing in securities generally or the securities in particular, or the ability of the relevant reference shares to track general market performance. No reference share issuer is responsible for, or has participated in the determination of, the timing, prices or quantities of the securities to be issued or in the determination or calculation of the equation by which the payment at maturity of the securities is to be determined. No reference share issuer has any liability in connection with the administration, marketing or trading of the securities.

You have no rights against the sponsor of the relevant fund or any issuers of the equity securities that comprise such fund

You will have no rights against the sponsor of the relevant fund or any issuers of the equity securities that comprise such fund. The securities are not sponsored, endorsed, sold or promoted by

any sponsor of such fund or any such issuer. No sponsor of the relevant fund or any such issuer has passed on the legality or suitability of, or the accuracy or adequacy of descriptions and disclosures relating to, the securities. No sponsor of the relevant fund or any such issuer makes any representation or warranty, express or implied, to you or any member of the public regarding the advisability of investing in securities generally or the securities in particular, or the ability of the relevant fund to track general market performance. The sponsor of such fund has no obligation to take our needs or your needs into consideration in determining, composing or calculating such fund. No sponsor of the relevant fund or any issuer of an equity security comprising such fund is responsible for, and none of them has participated in the determination of, the timing, prices or quantities of the securities to be issued or in the determination or calculation of the equation by which the redemption amount of the securities is to be determined. No sponsor of the relevant fund or any such issuer has any liability in connection with the administration, marketing or trading of the securities.

The United States federal income tax consequences of the securities are uncertain

No ruling is being requested from the Internal Revenue Service, or the IRS, with respect to the securities and we cannot assure you that the IRS or any court will agree with the tax treatment described under "Certain United States Federal Income Tax Considerations" in this product supplement.

The market value of the securities may be influenced by many factors that are unpredictable

Many factors, most of which are beyond our control, will influence the value of the securities and the price at which CSSU may be willing to purchase or sell the securities in the secondary market, including:

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 any other factor or factors.

Our hedging activity may affect the value of the reference shares or the stocks comprising the relevant fund and therefore the market value of the securities

We expect to hedge our obligations under the securities through one or more of our affiliates. This hedging activity will likely involve trading in the reference shares, or in the case of fund shares, one or more of the stocks comprising the relevant fund or in other instruments, such as options, swaps or futures, based upon the relevant reference shares, fund or stocks comprising such fund, as applicable. This hedging activity could affect the value of the reference shares or the stocks included in the relevant fund and therefore the market value of the securities. Assuming no change in market conditions or any other relevant factors, the price, if any, at which CSSU is willing to purchase the securities in secondary market transactions will likely be lower than the original issue price, since the original issue price included, and secondary market prices are likely to exclude, commissions paid with respect to the securities, as well as the projected profit included in the cost of hedging our obligations under the securities. In addition, any such prices may differ from values determined by pricing models used by CSSU, as a result of dealer discounts, mark-ups or other transaction costs. Moreover, this hedging activity may result in us or our affiliates receiving a profit, even if the market value of the securities declines.

Historical performance of the relevant reference shares or fund shares, as applicable, is not indicative of future performance

The future performance of the relevant reference shares or fund shares, as applicable, cannot be predicted based on their historical performance. We cannot guarantee that the price of any such reference shares or fund shares will be at a level that would result in a positive return on your overall investment in the securities.

The sponsor of the relevant fund is responsible for calculating and maintaining such fund. The relevant fund sponsor can add, delete or substitute the stocks comprising the relevant fund or make other methodological changes that could change the value of such fund at any time. The relevant fund sponsor may discontinue or suspend calculation or dissemination of the relevant fund.

If one or more of these events occurs, the calculation of the redemption amount payable at maturity will be adjusted to reflect such event or events. Please refer to "Description of the Securities—Adjustments to the calculation of a fund." Consequently, any of these actions could adversely affect the redemption amount payable at maturity and/or the market value of the securities.

In the case of the relevant fund, the policies of the fund sponsor or investment advisor, as applicable, and changes that affect such fund or the relevant tracking index could adversely affect the amount payable on your securities and their market value

The policies of the sponsor or investment advisor, as applicable, of the relevant fund concerning the calculation of the fund's net asset value, additions, deletions or substitutions of securities in such fund and the manner in which changes affecting the relevant tracking index are reflected in the fund could affect the market price of the shares of the fund and, therefore, the amount payable on your securities on the maturity date and the market value of your securities before that date. The amount payable on your securities and their market value could also be affected if the fund sponsor or investment advisor, as applicable, changes these policies, for example, by changing the manner in which it calculates the fund's net asset value, or if the fund sponsor or investment advisor, as applicable, discontinues or suspends calculation or publication of the fund's net asset value, in which case it may become difficult to determine the market value of the securities. If events such as these occur or if the closing price of shares of the fund is not available on the relevant valuation date because of a market disruption event or for any other reason, the calculation agent may determine the price of the shares of the fund on the relevant valuation date and thus the amount payable on the maturity date in a manner it considers appropriate in its sole discretion.

We and our affiliates generally do not have any affiliation with the investment advisor of a fund and are not responsible for its public disclosure of information

Each investment advisor of a fund advises that fund on various matters including matters relating to the policies, maintenance and calculation of the fund. Unless otherwise specified in the applicable pricing supplement, we and our affiliates generally are not affiliated with the investment advisor of a fund in any way (except for licensing arrangements) and have no ability to control or predict its actions, including any errors in or discontinuance of disclosure regarding their methods or policies relating to the fund. Except in cases where we or an affiliate is the investment advisor of a fund, the investment advisor is not involved in this offering of securities in any way and has no obligation to consider your interests as an owner of the securities in taking any actions relating to the fund that might affect the value of your securities.

Neither we nor any of our affiliates assumes any responsibility for the adequacy or accuracy of the information about a fund or the investment advisor of such fund (except to the extent that we or an affiliate is the investment advisor of such fund) contained in any public disclosure of information by such investment advisor. You, as an investor in the securities, should make your own investigation into the fund.

Even if the stocks held by the fund or included in the fund's tracking index are all part of the same industry, such stocks are not necessarily representative of that industry

Even if a fund or a fund's tracking index purports to be representative of a particular industry, the performance of such fund may not correlate with the performance of the entire industry as represented by the stocks held by the fund or included in the fund's tracking index. The fund may decline in value even if the industry as a whole rises in value. Furthermore, one or more of the issuers of the stocks held by the fund or included in the fund's tracking index may engage in new lines of business unrelated to the particular industry or cease to be involved in lines of business in the particular industry. The stocks held by the fund or included in the fund's tracking index may not vary even if one or more of the issuers of such stocks are no longer involved in the particular industry.

If the stocks held by the fund or included in the fund's tracking index are all part of the same sector, there are risks associated with a sector investment

If the stocks held by the fund or included in the fund's tracking index are all part of the same sector, the performance of securities linked to such fund is dependant upon the performance of issuers of stocks in a particular sector of the economy. Consequently, the value of the securities may be subject to greater volatility and be more adversely affected by a single economic, political or regulatory occurrence affecting the particular sector than an investment linked to a more broadly diversified underlying.

We cannot control the actions of the issuers whose stocks are held by the fund or included in the fund's tracking index

We cannot control the actions of the issuers of the stocks held by the fund or included in the fund's tracking index and actions by such issuers may have an adverse effect on the value of the securities or the stocks held by the fund or included in the fund's tracking index. In addition, these issuers are not involved in the offering of the securities and have no obligations with respect to the securities, including any obligation to take our interests or yours into consideration for any reason. These issuers will not receive any of the proceeds of this offering of the securities and are not responsible for, and have not participated in, the determination of the timing of, prices for, or quantities of, the securities to be issued. These issuers are not involved with the administration, marketing or trading of the securities and have no obligations with respect to the amount to be paid to you at maturity.

The correlation between the performance of a fund and the performance of such fund's tracking index may be imperfect

The performance of a fund is linked principally to the performance of the fund's tracking index. However, the performance of a fund is also generally linked in part to shares of other funds because funds generally invest a specified percentage, e.g., 10%, of their assets in the shares of other funds. In addition, while the performance of a fund is linked principally to the performance of such fund's tracking index, funds generally invest in a representative sample of the stocks included in such fund's tracking index and generally do not hold all or substantially all of the stocks included in such fund's tracking index. Finally, the performance of a fund and of the fund's tracking index will generally vary due to transaction costs, certain corporate actions and timing variances.

Imperfect correlation between the stocks held by a fund and the stocks included in such fund's tracking index; the performance of the shares of other funds, if applicable; rounding of prices; changes to a fund's tracking index; and changes to regulatory policies, may cause the performance of a fund to differ from the performance of the fund's tracking index. In addition, because shares of funds are traded on exchanges and are subject to market supply and investor demand, the market value of one share of a fund may differ from its net asset value per share and the shares of a fund may trade at, above or below their net asset value per share.

Because of the potential discrepancies identified above, the return on a fund may correlate imperfectly with the return on the fund's tracking index.

There is no assurance that an active trading market will continue for the shares of the relevant fund or that there will be liquidity in the trading market

Although the shares of a fund to which your securities may be linked, are listed for trading on various securities exchanges and a number of similar products have been traded on other securities exchanges for varying periods of time, there is no assurance that an active trading market will continue for the shares of such fund or that there will be liquidity in the trading market.

In addition, each fund is subject to management risk, which is the risk that the investment advisor's investment strategy, the implementation of which is subject to a number of constraints, may not produce the intended results. For example, an investment advisor may invest a portion of the fund's assets in securities not included in the relevant industry or sector but which the investment advisor believes will help the fund track the relevant industry or sector.

An investment in the securities may be subject to risks associated with non-U.S. securities markets

The stocks comprising the relevant fund may have been issued by non-U.S. companies. Investments in securities linked to the value of such non-U.S. equity securities involve risks associated with the securities markets in those countries, including risks of volatility and governmental intervention in those markets and cross shareholdings in companies in certain countries. Also, there is generally less publicly available information about companies in some of these jurisdictions than there is about U.S. companies that are subject to the reporting requirements of the Securities and Exchange Commission (the "SEC"), and generally non-U.S. companies are subject to accounting, auditing and financial reporting standards and requirements and securities trading rules different from those applicable to U.S. reporting companies.

The prices of securities in non-U.S. jurisdictions may be affected by political, economic, financial and social factors in such markets, including changes in a country's government, economic and fiscal policies, currency exchange laws and other foreign laws or restrictions. Moreover, the economies in such countries may differ favorably or unfavorably from the economy of the United States in such respects as growth of gross national product, rate of inflation, capital reinvestment, resources and self sufficiency. Such countries may be subjected to different and, in some cases, more adverse economic environments.

The economies of emerging market countries in particular face several concerns, including the relatively unstable governments which may present the risks of nationalization of businesses, restrictions on foreign ownership and prohibitions on the repatriation of assets, and which may have less protection of property rights than more developed countries. These economies may also be based on only a few industries, be highly vulnerable to changes in local and global trade conditions and may suffer from extreme and volatile debt burdens or inflation rates. In addition, local securities markets may trade a small number of securities and may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of holdings difficult or impossible. The risks of the economies of emerging market countries are relevant for securities linked to a fund composed of securities traded in one or more emerging market countries.

The securities may be subject to foreign currency risk if the relevant fund is comprised of foreign equity securities

If the relevant fund and the stocks comprising such fund are not denominated in the same currency as such fund, the securities may be subject to foreign currency risk. Because the prices of the stocks comprising the relevant fund will be converted into the currency in which such fund is denominated (the "base currency") for the purposes of calculating the value of such fund, your investment will be exposed to currency exchange risk with respect to each of the countries represented in such fund which do not use the base currency. Your net exposure to such risk will depend on the extent to which the currencies in which the stocks comprising such fund are denominated, other than the base currency, strengthen or weaken relative to the base currency. If the base currency strengthens relative to any of the currencies in which the stocks comprising such fund are denominated, the value of such fund may be adversely affected, and the redemption amount payable on the securities at maturity may be reduced. Of particular importance to potential currency exchange risks are: existing and expected rates of inflation, existing and expected interest rate levels, the balance of payments, and the extent of governmental surpluses or deficits in the relevant countries represented in any relevant

fund. All of these factors are in turn sensitive to the monetary, fiscal and trade policies pursued by the governments of the countries represented in such fund and other countries important to international trade and finance.

If the relevant fund is comprised of stocks denominated in a currency other than U.S. dollars, the securities, which are denominated in U.S. dollars, are subject to foreign currency risk because the return on the securities is linked to the performance of such fund, the value of which is dependant on the stocks denominated in a currency other than U.S. dollars. Foreign currency risks include, but are not limited to, convertibility risk and market volatility and potential interference by foreign governments through regulation of local markets, foreign investment or particular transactions in foreign currency. These factors may adversely affect the values of the stocks comprising such fund, the price of such fund shares and the value of the securities.

If the relevant reference shares are ADSs, fluctuations in exchange rates will affect your investment

There are significant risks related to an investment in securities linked, in whole or in part, to the ADSs of a foreign issuer, which are quoted and traded in U.S. dollars, each representing an underlying equity security that is quoted and traded in a foreign currency. The ADSs which are quoted and traded in U.S. dollars, may trade differently from the applicable underlying equity security or underlying equity securities. In recent years, the rates of exchange between the U.S. dollar and some other currencies have been highly volatile and this volatility may continue in the future. These risks generally depend on economic and political events over which we have no control. Fluctuations in any particular exchange rate that have occurred in the past are not necessarily indicative, however, of fluctuations that may occur during the term of the securities. Changes in the exchange rate between the U.S. dollar and a foreign currency may affect the U.S. dollar equivalent of the price of such underlying equity security on non-U.S. securities markets and, as a result, may affect the market price of such ADS, as applicable, which may consequently affect the value of the securities.

Foreign exchange rates can either float or be fixed by sovereign governments. Exchange rates of the currencies used by most economically developed nations are permitted to fluctuate in value relative to the U.S. dollar and to each other. However, from time to time governments and, in the case of countries using the euro, the European Central Bank, may use a variety of techniques, such as intervention by a central bank, the imposition of regulatory controls or taxes or changes in interest rates to influence the exchange rates of their currencies. Governments may also issue a new currency to replace an existing currency or alter the exchange rate or relative exchange characteristics by a devaluation or revaluation of a currency. These governmental actions could change or interfere with currency valuations and currency fluctuations that would otherwise occur in response to economic forces, as well as in response to the movement of currencies across borders. As a consequence, these government actions could adversely affect an investment in securities linked, in whole or in part, to the ADSs of one or more foreign issuers, which are quoted and traded in U.S. dollars, each representing an underlying equity security that is quoted and traded in a foreign currency.

We will not make any adjustment or change in the terms of the securities in the event that exchange rates should become fixed, or in the event of any devaluation or revaluation or imposition of exchange or other regulatory controls or taxes, or in the event of other developments affecting the U.S. dollar or any relevant foreign currency. You will bear those risks.

If the relevant reference shares are ADSs, an investment in the securities is subject to risks associated with non-U.S. securities markets

If the securities are linked, in whole or in part, to the value of the ADSs of a foreign issuer representing interests in non-U.S. equity securities an investment in the securities involves risks associated with the securities markets in those countries where the relevant non-U.S. equity securities are traded, including risks of markets volatility, governmental intervention in those markets and cross shareholdings in companies in certain countries. Also, non-U.S. companies are generally subject to accounting, auditing and financial reporting standards and requirements, and securities trading rules different from those applicable to U.S. reporting companies.

The prices of equity securities in non-U.S. markets may be affected by political, economic, financial and social factors in such markets, including changes in a country's government, economic and fiscal policies, currency exchange laws or other laws or restrictions. Moreover, the economies of such countries may differ favorably or unfavorably from the economy of the United States in such respects as growth of gross national product, rate of inflation, capital reinvestment, resources and self sufficiency. Such countries may be subjected to different and, in some cases, more adverse economic environments.

Some or all of these factors may influence the price of the ADSs and therefore, an investment in securities linked to such ADSs, as applicable. The impact of any of these factors set forth above may enhance or offset some or all of any change resulting from another factor or factors. You cannot predict the future performance of the ADSs based on their historical performance. The value of the ADSs may decrease such that you may not receive any return of your investment. There can be no assurance that the price of the ADSs will not decrease so that at maturity you will not lose some or all of your investment.

There are important differences between the rights of holders of ADSs and the rights of holders of the equity securities of a foreign company

If your securities are linked, in whole or in part, to the performance of the ADSs of a foreign issuer, you should be aware that your securities are linked, in whole or in part, to such ADSs and not to the securities underlying such ADSs, and there exist important differences between the rights of holders of ADSs and the securities underlying ADSs. Each ADS is a security evidenced by American Depositary Receipts that represents a specified number of shares of the equity securities of a foreign issuer. Generally, the ADSs are issued under a deposit agreement, which sets forth the rights and responsibilities of the depositary, the foreign issuer and holders of such ADSs, which may be different from the rights of holders of the equity securities of the foreign issuer. For example, the foreign issuer may make distributions in respect of its equity securities that are not passed on to the holders of its ADSs. Any such differences between the rights of holders of the ADSs and holders of the applicable underlying equity security may be significant and may materially and adversely affect the value of the securities.

In some circumstances, the payment you receive on the securities may be based on the equity securities (or ADSs, as applicable) of one or more companies that are not the relevant reference share issuer

Following certain corporate events relating to the relevant reference shares where the reference share issuer is not the surviving entity, a portion of the amount you receive at maturity may be based on the equity securities of a successor to such reference share issuer or any cash or any other assets distributed to holders of such reference shares as a result of such corporate event. The occurrence of these corporate events and the consequent adjustments may materially and adversely affect the value of the securities. We describe the specific corporate events that can lead to these adjustments and the

procedures for selecting Exchange Property (as described below) in the section of this product supplement called "Description of the Securities—Anti-dilution adjustments—Reorganization events."

In addition, for securities linked to the performance an ADS, if such ADS is no longer listed or admitted to trading on a U.S. securities exchange registered under the Exchange Act, or included in the OTC Bulletin Board, or if the ADS facility between the reference share issuer and the ADS depositary is terminated for any reason, the calculation agent will have the option to either (a), (i) replace that ADS with the ADS of a company selected from among the ADSs of three companies organized in, or with its principal executive office located in, the country in which the reference share issuer of that original ADS is organized, or has its principal executive office, and that are then registered to trade on the New York Stock Exchange ("NYSE") or The NASDAQ Stock Market with the same primary Standard Industrial Classification Code ("SIC Code") as that original ADS that, in the sole discretion of the calculation agent, is the most comparable to such original ADS taking into account such factors as the calculation agent deems relevant, including, without limitation, market capitalization, dividend history and stock price volatility or (ii) in certain circumstances, replace that ADS, as applicable with the ADS of a company that is organized in, or with its principal executive office located in, the country in which the issuer of the original ADS is organized, or has its principal executive office and that are then registered to trade on the NYSE or The NASDAQ Stock Market that, in the sole discretion of the calculation agent, is the most comparable to the original ADS taking into account such factors as the calculation agent deems relevant, including, without limitation, market capitalization, dividend history and stock price volatility and that is within the same Division and Major Group classification (as defined by the Office of Management and Budget) as the primary SIC Code for the original ADS or (iii) in certain circumstances, replace the ADS with the equity securities of a company that is then registered to trade on the NYSE or The NASDAQ Stock Market with the same primary SIC Code as the original ADS that in the sole discretion of the calculation agent, is the most comparable to the original ADS taking into account such factors as the calculation agent deems relevant including, without limitation, market capitalization, dividend history and stock price volatility or (b) deem the applicable underlying equity securities to be the reference shares. You should read the section of this product supplement called "Description of the Securities—Anti-dilution adjustments—Delisting of ADSs or termination of ADS facility" for more information. Replacing the original ADS serving as the reference shares with another ADS may materially and adversely affect the value of the securities.

We, CSSU and/or any other affiliate may from time to time buy or sell the relevant reference shares, fund shares, futures contracts related to reference shares, fund shares or stocks comprising the relevant fund or derivative instruments related to the relevant reference shares, fund shares or stocks comprising the relevant fund for our or their own accounts in connection with our or their normal business practices. Although we do not expect them to, these transactions could affect the price of such reference shares or fund shares and thus affect the market value of the securities.

In addition, because Credit Suisse International, which is initially acting as the calculation agent for the securities, is an affiliate of ours, potential conflicts of interest may exist between the calculation agent and you, including with respect to certain determinations and judgments that the calculation agent must make in determining amounts due to you.

Finally, we and our affiliates may, now or in the future, engage in business with any reference share issuer, fund sponsor or the issuers of the stocks comprising the relevant fund, including providing advisory services. These services could include investment banking and mergers and acquisitions advisory services. These activities could present a conflict of interest between us or our affiliates and you. We or our affiliates may have also published and may in the future publish research reports regarding any reference share issuer, fund sponsor or issuer of a stock included in the relevant fund.

This research is modified periodically without notice and may express opinions or provide recommendations that may affect the price of any reference shares or fund shares, or the stocks included in any fund and, consequently, the price of the securities and the redemption amount payable at maturity.

The inclusion in the original issue price of each agent's commission and the estimated cost of hedging our obligations under the securities through one or more of our affiliates is likely to adversely affect the value of the securities prior to maturity

While the payment at maturity will be based on the full principal amount of your securities as described in the applicable pricing supplement, the original issue price of the securities includes each agent's commission and the estimated cost of hedging our obligations under the securities through one or more of our affiliates. Such agent's commission includes the profit our affiliates expect to realize in consideration for assuming the risks inherent in providing such hedge. As a result, assuming no change in market conditions or any other relevant factors, the price, if any, at which CSSU will be willing to purchase the securities from you in secondary market transactions, if at all, will likely be lower than the original issue price. In addition, any such prices may differ from values determined by pricing models used by CSSU a result of such compensation or other transaction costs.

The calculation agent will make adjustments to the share adjustment factor for certain events affecting the reference shares or fund shares, as applicable. The calculation agent is not required, however, to make such adjustments in response to all such events. If such an event occurs and the calculation agent is not required to make an adjustment, the value of the securities may be materially and adversely affected. See "Description of the Securities—Anti-dilution adjustments" for further information.

The calculation agent may, in its discretion, determine that the markets have been affected in a manner that prevents it from properly valuing the relevant reference shares or funds shares on any trading day during the term of the securities or from calculating the redemption amount. These events may include disruptions or suspensions of trading in the markets as a whole. If the calculation agent, in its discretion, determines that any of these events prevents us or any of our affiliates from properly hedging our obligations under the securities, it is possible that one or more of the valuation dates and the maturity date will be postponed and your return will be adversely affected. No interest or other payment will be payable as a result of such postponement.

A market disruption event may postpone the calculation of the closing price on a valuation date or the maturity date

If the calculation agent determines that a market disruption event, as defined herein, exists in respect of the relevant reference shares or fund shares, as applicable, on a valuation date, then such valuation date for such reference shares or fund shares will be postponed to the first succeeding exchange business day, as defined below, on which the calculation agent determines that no market disruption event exists in respect of such reference shares or fund shares, unless the calculation agent determines that a market disruption event in respect of such reference shares or fund shares exists on each of the five exchange business days immediately following the scheduled valuation date. In that case, (a) the fifth exchange business day following the scheduled valuation date will be deemed to be the valuation date for such reference shares or fund shares, as applicable, notwithstanding the existence of a market disruption event in respect of such reference shares or fund shares, and (b) the calculation agent will determine the closing price for such reference shares or fund shares, as applicable, for such

valuation date on that fifth succeeding exchange business day using exchange traded prices on the relevant exchanges (as determined by the calculation agent in its sole and absolute discretion) or, if trading in such reference shares or fund shares, as applicable, has been materially suspended or materially limited, its good faith estimate of the prices that would have prevailed on the applicable exchanges (as determined by the calculation agent in its sole and absolute discretion) but for the suspension or limitation, as of the valuation time on that deemed final valuation date, of the reference shares or fund shares, as applicable.

In the event that a market disruption event exists in respect of the relevant reference shares or fund shares, as applicable, on the final valuation date, the maturity date of the securities will be postponed to the fifth business day following the day as of which a closing price for such reference shares or fund shares, as applicable, has been calculated. Consequently, the existence of a market disruption event could result in a postponement of the maturity date, but no interest or other payment will be payable because of such postponement. Please refer to "Description of the Securities—Maturity date" and "Description of the Securities—Market disruption events" herein.

We and our affiliates and agents may publish research, express opinions or provide recommendations that are inconsistent with investing in or holding the securities and any such research, opinions or recommendations could affect the price of the relevant reference shares or fund shares, as applicable, to which the securities are linked or the market value of the securities

We or our affiliates and agents publish research from time to time on financial markets and other matters that may influence the value of the securities, and we may express opinions or provide recommendations that are inconsistent with purchasing or holding the securities. Any research, opinions or recommendations expressed by us, our affiliates or agents may not be consistent with each other and may be modified from time to time without notice.

We have been granted, or will be granted, a non-exclusive right to use the relevant fund and related trademarks in connection with the offering of the securities. If we breach our obligations under any license, the sponsors of such fund may have the right to terminate the license. If the sponsors choose to terminate their license agreement with us, we may no longer have the right under the terms of the license agreement to use the relevant fund and related trademarks in connection with the securities until their maturity. If our right to use the relevant fund to which your securities are linked is suspended or terminated for any reason, it may become difficult for us to determine the level of that fund and consequently the interest, payment at maturity or any other amounts payable on your securities. The calculation agent in this case will determine the relevant fund level or the fair market value of the securities in its sole discretion.

For further information about our company, we refer you to the accompanying prospectus supplement and prospectus and the documents referred to under "Incorporation by Reference" on page S-9 of the prospectus supplement and "Where You Can Find More Information" on page 2 of the accompanying prospectus.

Unless otherwise specified in the applicable pricing supplement, we intend to use the proceeds from each offering (as indicated in the applicable pricing supplement) for our general corporate purposes, which may include the refinancing of our existing indebtedness outside Switzerland. We may also use some or all of the proceeds from any offering to hedge our obligations under the securities. In addition, we may also invest the proceeds temporarily in short-term securities.

One or more of our affiliates before and following the issuance of any securities may acquire or dispose of positions relating to the relevant reference shares or fund shares, as applicable, or listed or over-the-counter options contracts in, or other derivatives or synthetic instruments related to, such reference shares or fund shares, as applicable, or the stocks included in any fund to hedge our obligations under the securities. In the course of pursuing such a hedging strategy, the price at which such positions may be acquired or disposed of may be a factor in determining the prices of the relevant reference shares or fund shares, as applicable,. Although we and our affiliates have no reason to believe that our or their hedging activities will have a material impact on the price of any relevant reference shares or fund shares, as applicable, there can be no assurance that the prices of such reference shares or fund shares, as applicable, will not be affected.

From time to time after issuance and prior to the maturity of the securities, depending on market conditions (including the prices of the reference shares or fund shares, as applicable), in connection with hedging certain of the risks associated with the securities, we expect that one or more of our affiliates will increase or decrease their initial hedging positions using dynamic hedging techniques and may take long or short positions in listed or over-the-counter options contracts in, or other derivative or synthetic instruments related to, the reference shares, or the stocks comprising a fund. In addition, we or one or more of our affiliates may take positions in other types of appropriate financial instruments that may become available in the future. To the extent that we or one or more of our affiliates have a hedge position in any reference shares or the stocks comprising any fund, we or one or more of our affiliates may liquidate a portion of those holdings at or about the time of the maturity of any securities. Depending, among other things, on future market conditions, the aggregate amount and the composition of such positions are likely to vary over time. Our or our affiliates' hedging activities will not be limited to any particular exchange or market.

The original issue price of the securities will include the commissions paid to CSSU with respect to the securities and the cost of hedging our obligations under the securities. The cost of hedging includes the projected profit that our subsidiaries expect to realize in consideration for assuming the risks inherent in managing the hedging transactions. Since hedging our obligations entails risk and may be influenced by market forces beyond our or our subsidiaries' control, such hedging may result in a profit that is more or less than initially projected, or could result in a loss.

This description of the terms of the securities adds information to the description of the general terms and provisions of debt securities in the accompanying prospectus supplement and prospectus. If this description differs in any way from the description in the accompanying prospectus supplement and prospectus, you should rely on this description. If the terms described in the applicable pricing supplement are inconsistent with those described herein or in the accompanying prospectus supplement or prospectus, the terms described in the applicable pricing supplement will control.

The securities are medium-term notes as described in the accompanying prospectus supplement and are linked to the performance of the reference shares or fund shares. The applicable pricing supplement will specify the relevant reference shares or fund shares, as applicable, to which the securities are linked.

The securities are not subject to redemption at our option or repayment at the option of any security holder prior to maturity and are not subject to the defeasance provisions described in the accompanying prospectus under "Description of Debt Securities—Defeasance."

The maturity date of the securities will be specified in the applicable pricing supplement and is subject to postponement as described herein under "—Market disruption events." Unless otherwise specified in the applicable pricing supplement, no interest or other payment will be payable because of any postponement of the maturity date.

Unless otherwise specified in the applicable pricing supplement, the securities will accrue interest at a rate per annum from and including the issue date of the securities to and including the maturity date.

The applicable pricing supplement will set forth the interest rate and the interest payment dates applicable to the securities. If any such interest payment date is not a business day, interest will be payable subject to the modified following business day convention, which means that payment will be made on the first following business day, unless that business day falls in the next calendar month, in which case the payment will be made on the first preceding business day. Unless otherwise specified in the applicable pricing supplement, interest will be computed on the basis of a 360-day year of twelve 30-day months.

Unless previously redeemed, or purchased by us and cancelled, each security will be redeemed on the maturity date at the redemption amount described herein.

Unless otherwise specified in the applicable pricing supplement, the redemption amount of the securities will depend on the performance of the relevant reference shares or fund shares, as applicable, and whether a knock-in event occurs. The redemption amount will be determined as follows:

Any payment you will be entitled to receive at maturity is subject to our ability to pay our obligations as they become due.

Unless otherwise specified in the applicable pricing supplement, the following terms used in this product supplement have the following definitions:

The "trade date" will be the date set forth in the applicable pricing supplement.

The "initial share price," "final share price," "observation period" and "knock-in level" will be specified in the applicable pricing supplement.

The price or closing price of the relevant reference shares and the fund shares may be adjusted in certain circumstances. See "Description of the Securities—Anti-dilution adjustments" for further information.

For reference shares, the "price" at any time during the term of the securities will equal the price of one share for such reference shares on the relevant exchange at such time, as specified in the applicable pricing supplement, multiplied by the share adjustment factor applicable at such time, as determined by the calculation agent.

For fund shares, the "price" of such fund shares at any time during the term of the securities will equal the price for one share of such fund displayed on the relevant Bloomberg page at such time, as specified in the applicable pricing supplement (or such other page as may replace that page on that service, or if unavailable on that service, any other service displaying that level), multiplied by the share adjustment factor applicable at such time, as determined by the calculation agent.

For reference shares, the "closing price" for one share of the reference shares (or one unit of any other security for which a closing price must be determined) on any exchange business day or trading day means:

For fund shares, the "closing price", on any exchange business day or trading day, will be the last reported sale price for one share of the fund, regular way, of the principal trading session on such day on the New York Stock Exchange (or such other national securities exchange on which the fund is listed or admitted to trading) multiplied by the share adjustment factor, which will initially be set at 1.0, subject to the provisions described under "—Adjustments to the calculation of a fund" herein.

A "business day" is any day, other than a Saturday, Sunday or a day on which banking institutions in the City of New York, New York are generally authorized or obligated by law or executive order to close.

An "exchange business day" is any day that is (or, but for the occurrence of a market disruption event, would have been) a day on which trading is generally conducted on the exchanges or related exchanges (each as defined below), other than a day on which one or more of the exchanges and related exchanges is scheduled to close prior to its regular weekday closing time. "Exchange" means the principal exchange on which any reference shares or fund shares is traded. "Related exchange" means any exchange on which futures or options contracts relating to the reference shares or fund shares are traded.

A "trading day" is any day, as determined by the calculation agent, on which trading is generally conducted on the relevant exchange for the reference shares or fund shares, as applicable.

For fund shares, the "share adjustment factor" will be set to 1.0 on the date the securities are priced for initial sale to the public and is subject to adjustment as described under "—Anti-dilution adjustments for funds" herein.

For reference shares, the "share adjustment factor" will be set to 1.0 on the date the securities are priced for initial sale to the public and is subject to adjustment as described under "—Anti-dilution adjustments for reference shares" herein

The "valuation date" will be the date or dates specified in the applicable pricing supplement, or the next succeeding exchange business day if the scheduled valuation date is not an exchange business day, subject to the market disruption provisions described in "—Market disruption events" herein.

in each case, as determined by the calculation agent in its sole discretion; and a determination by the calculation agent in its sole discretion that any event described above materially interfered with our ability or the ability of any of our affiliates to effect transactions in such reference shares or any instrument related to such reference shares or to adjust or unwind all or a material portion of any hedge position in such reference shares with respect to the securities.

If the calculation agent determines that on a valuation date a market disruption event exists in respect of the reference shares, then that valuation date will be postponed to the first succeeding exchange business day on which the calculation agent determines that no market disruption event exists in respect of such reference shares, unless the calculation agent determines that a market disruption event in respect of such reference shares exists on each of the five exchange business days immediately following the valuation date. In that case, (a) the fifth succeeding exchange business day after the scheduled valuation date will be deemed to be the valuation date for such reference shares, notwithstanding the market disruption event in respect of such relevant shares, and (b) the calculation agent will determine the closing price for the valuation date on that deemed valuation date in accordance with the formula for and method of calculating such reference shares last in effect prior to the commencement of the market disruption event using its good faith estimate of the settlement price that would have prevailed on the applicable exchange but for the suspension or limitation, as of the relevant valuation time on that deemed valuation date, of the reference shares.

Unless otherwise specified in the applicable pricing supplement, in the event that a market disruption event exists in respect of the reference shares on the final valuation date, the maturity date of the securities will be the fifth business day following the day on which the closing price for the valuation date for the reference shares has been calculated.

If the existence of a market disruption event results in a postponement of the maturity date, no interest or other payment will be payable because of such postponement.

in each case, as determined by the calculation agent in its sole discretion; and a determination by the calculation agent in its sole discretion that any event described above materially interfered with our ability or the ability of any of our affiliates to effect transactions in the fund shares or any instrument related to the fund shares or to adjust or unwind all or a material portion of any hedge position in the fund with respect to the securities.

If the calculation agent determines that on a valuation date a market disruption event exists in respect of a fund, then that valuation date will be postponed to the first succeeding exchange business day on which the calculation agent determines that no market disruption event exists in respect of such fund, unless the calculation agent determines that a market disruption event in respect of such fund exists on each of the five exchange business days immediately following the valuation date. In that case, (a) the fifth succeeding exchange business day after the scheduled valuation date will be deemed to be the valuation date for such fund, notwithstanding the market disruption event in respect of such fund, and (b) the calculation agent will determine the closing price for the valuation date on that deemed valuation date in accordance with the formula for and method of calculating such fund last in effect prior to the commencement of the market disruption event using its good faith estimate of the

settlement prices that would have prevailed on the applicable exchange but for the suspension or limitation, as of the relevant valuation time on that deemed valuation date, of each such security comprising the fund (subject to the provisions described under "—Adjustments to the calculation of a fund") herein.

Unless otherwise specified in the applicable pricing supplement, in the event that a market disruption event exists in respect of the fund on the final valuation date, the maturity date of the securities will be the fifth business day following the day on which the closing price for the valuation date for the fund has been calculated.

If the existence of a market disruption event results in a postponement of the maturity date, no interest or other payment will be payable because of such postponement.

If the fund (or a successor fund (as defined herein)) is de-listed from the relevant exchange, liquidated or otherwise terminated, the calculation agent will substitute an exchange traded fund that the calculation agent determines, in its sole discretion, is comparable to the discontinued fund (or such successor fund) (such fund being referred to herein as a "successor fund"). If the fund (or a successor fund) is de-listed, liquidated or otherwise terminated and the calculation agent determines that no successor fund is available, then the calculation agent will, in its sole discretion, calculate the appropriate closing price of one share of the fund by a computation methodology that the calculation agent determines will as closely as reasonably possible replicate the fund. If a successor fund is selected or the calculation agent calculates the closing price by a computation methodology that the calculation agent determines will as closely as reasonably possible replicate the fund, that successor fund or closing price will be substituted for the fund (or such successor fund) for all purposes of the securities.

then, from and after that time, the calculation agent will make those calculations and adjustments as, in the good faith judgment of the calculation agent, may be necessary in order to arrive at a closing price of an exchange traded fund comparable to the fund (or such successor fund) as if those changes or modifications had not been made, and calculate the closing level with reference to the fund (or such successor fund), as adjusted.

The calculation agent also may determine that no adjustment is required by the modification of the method of calculation.

The calculation agent will be solely responsible for the method of calculating the closing price of one share of the fund (or any successor fund) and of any related determinations and calculations, and its determinations and calculations with respect thereto will be conclusive in the absence of manifest error.

For purposes of these adjustments, except as noted below, if an ADS is serving as a reference share, all adjustments to the share adjustment factor for such reference shares will be made as if the applicable underlying equity security is serving as such reference share. Therefore, for example, if the applicable underlying equity security is subject to a two-for-one stock split and assuming the share adjustment factor for such reference shares is equal to one, the share adjustment factor for such reference shares would be adjusted to be equal to two. If the relevant reference shares are ADSs, the term "dividend" used in this section, with respect to such reference shares, will mean, unless we specify otherwise in the relevant pricing supplement, the dividend paid by the issuer of the applicable underlying equity security, net of any applicable foreign withholding or similar taxes that would be due on dividends paid to a U.S. person that claims and is entitled to a reduction in such taxes under an applicable income tax treaty, if available.

If ADSs are serving as the relevant reference shares, no adjustment to the applicable ADS price or the applicable share adjustment factor, including those described below, will be made if (1) holders of such ADSs are not eligible to participate in any of the transactions described below or (2) (and to the extent that) the calculation agent determines in its sole discretion that the issuer or the depositary for such ADSs has adjusted the number of shares of the applicable underlying equity security represented by each such ADS so that such ADS price would not be affected by the corporate event in question. However, to the extent that the number of shares of the applicable underlying equity security represented by each such ADS is changed for any other reason, appropriate adjustments to the anti-dilution adjustments described herein (which may include ignoring such provision, if appropriate) will be made to reflect such change.

If the relevant reference shares are subject to a stock split or reverse stock split, then once any split has become effective, the share adjustment factor relating to such reference shares will be adjusted so that the new share adjustment factor equals the product of:

If the relevant reference shares are subject to a (i) stock dividend, i.e., an issuance of additional shares of such reference shares, that is given ratably to all or substantially all holders of such reference shares, or (ii) distribution of shares of such reference shares as a result of the triggering of any provision of the corporate charter of the reference share issuer, then, once the dividend or distribution has become effective and such reference shares are trading ex-dividend, the share adjustment factor for such reference shares will be adjusted so that the new share adjustment factor for such reference shares equals the prior share adjustment factor for such reference shares plus the product of:

If the reference share issuer distributes shares of capital stock, evidences of indebtedness or other assets or property of such reference share issuer to all or substantially all holders of such reference shares (other than (i) dividends, distributions, rights or warrants referred to under "—Stock splits and reverse stock splits" or "—Stock dividends or distributions" above or "—Issuance of transferable rights or warrants" below and (ii) cash distributions or dividends referred under "—Extraordinary cash dividends or distributions" below), then, once the dividend or distribution has become effective and such reference shares are trading ex-dividend, the share adjustment factor for such reference shares will be adjusted so that the new share adjustment factor for such reference shares equals the product of:

The "current market price" of the reference shares means the arithmetic average of the closing prices of one share of such reference shares for the ten exchange business days prior to the exchange business day immediately preceding the ex-dividend date of the dividend or distribution requiring an adjustment to the share adjustment factor for such reference shares.

The "ex-dividend date," with respect to a dividend or other distribution on the reference shares, means the first trading day on which transactions in such reference shares trade on the relevant exchange without the right to receive that dividend or other distribution.

The "fair market value" of any such distribution means the value of such distribution on the ex-dividend date for such distribution, as determined by the calculation agent. If such distribution consists of property traded on the ex-dividend date on a U.S. national securities exchange or, if the applicable reference shares are ADSs on a non-U.S. securities exchange or market, the fair market value will equal the closing price of such distributed property on such ex-dividend date, as determined by the calculation agent.

Notwithstanding the foregoing, a distribution on the reference shares described in clause (a), (d) or (e) of the section entitled "—Reorganization events" below that also would require an adjustment under this section will not cause an adjustment to the share adjustment factor for such reference shares and will only be treated as a reorganization event (as defined below) pursuant to clause (a), (d) or (e) under the section entitled "—Reorganization events." A distribution on a reference share described in the section entitled "—Issuance of transferable rights or warrants" that also would require an adjustment under this section will only cause an adjustment pursuant to the section entitled "—Issuance of transferable rights or warrants."

If the reference share issuer pays dividends or makes other distributions consisting exclusively of cash to all holders of such reference shares during any fiscal quarter during the term of the securities, in an aggregate amount that, together with other such cash dividends or distributions made previously during such quarterly fiscal period with respect to which an adjustment to the share adjustment factor for such reference shares has not previously been made under this "—Extraordinary cash dividends or distributions" section, exceeds the dividend threshold for such reference shares, then, once the dividend or distribution has become effective and such reference shares are trading ex-dividend, the share adjustment factor for such reference shares will be adjusted so that the new share adjustment factor for such reference shares equals the product of:

For the avoidance of doubt, the share adjustment factor for the relevant reference shares may be adjusted more than once in any particular quarterly fiscal period because of cash dividends or distributions that exceed the dividend threshold for such reference shares. If the share adjustment factor for such reference shares has been previously adjusted in a particular quarterly fiscal period because of cash dividends or distributions that exceed the dividend threshold for such reference shares, subsequent adjustments will be made if the reference share issuer pays cash dividends or makes other distributions during such quarterly fiscal period in an aggregate amount that, together with other such cash dividends or distributions since the last adjustment to the share adjustment factor for such reference shares (because of cash dividends or distributions that exceed the dividend threshold for such reference shares) exceeds the dividend threshold for such reference shares. Such subsequent adjustments to the share adjustment factor for such reference share will only take into account the cash dividends or distributions during such quarterly fiscal period made since the last adjustment to the share adjustment factor for such reference shares because of cash dividends or distributions that exceed the dividend threshold for such reference shares.

The "dividend threshold," with respect to the relevant reference shares, is equal to the sum of (x) the immediately preceding cash dividend(s) or other cash distribution(s) paid in the preceding quarterly fiscal period, if any, per share of such reference shares plus (y) 10% of the closing price of one share of such reference shares on the trading day immediately preceding the ex-dividend date, unless otherwise specified in the relevant pricing supplement.

If the reference share issuer issues transferable rights or warrants to all holders of such reference shares to subscribe for or purchase such reference shares, including new or existing rights to purchase such reference shares at an exercise price per share less than the closing price of one share of such reference shares on both (i) the date the exercise price of such rights or warrants is determined and (ii) the expiration date of such rights and warrants pursuant to a shareholder's rights plan or arrangement, and if the expiration date of such rights or warrants precedes the maturity date of the securities, then the share adjustment factor for such reference shares will be adjusted on the business day immediately following the issuance of such transferable rights or warrants so that the new share adjustment factor for such reference shares equals the prior share adjustment factor for such reference shares plus the product of:

The number of reference shares that can be purchased will be based on the closing price of such reference shares on the date the new share adjustment factor for such reference shares is determined. The cash value of such warrants or rights, if the warrants or rights are traded on a U.S. national securities exchange or, in the case of reference shares that are ADSs, on a non-U.S. securities exchange or market, will equal the closing price of such warrant or right, or, if the warrants or rights are not traded on a U.S. national securities exchange or a non-U.S. securities exchange or market, as

applicable, will be determined by the calculation agent and will equal the average (mean) of the bid prices obtained from three dealers at 3:00 p.m., New York City time, on the date the new share adjustment factor for such reference share is determined, provided that if only two such bid prices are available, then the cash value of such warrants or rights will equal the average (mean) of such bids and if only one such bid is available, then the cash value of such warrants or rights will equal such bid.

then the initial share price and the final share price for such reference shares will be adjusted as set forth below and the share adjustment factor will be adjusted as required in connection with any adjustments to the initial share price and final share price.

If a reorganization event with respect to the relevant reference shares occurs, in each case as a result of which the holders of such reference shares receive Exchange Property, then the final share price for such reference shares will be determined by reference to the value of the Exchange Property following the effective date for such reorganization event (or, if applicable, in the case of a spin-off event, the initial share price for such reference shares will be adjusted based on the closing price of one share of such reference shares immediately preceding and immediately succeeding the ex-dividend date for the distribution of equity securities subject to such spin-off event). The value of the Exchange Property will be calculated as the sum of the value of the components of the Exchange Property as described below:

"Exchange Property," with respect to the relevant reference shares that is subject to a reorganization event, will consist of any reference shares continued to be held by the holders of such reference shares, and any securities, cash or any other assets distributed to the holders of such reference shares with respect to one share, in or as a result of, the reorganization event. No interest will accrue on any Exchange Property.

In the event Exchange Property consists of securities, those securities will, in turn, be subject to the anti-dilution adjustments contained herein.

In the case of a consummated and completed in full tender or exchange offer or going-private transaction involving Exchange Property of a particular type, Exchange Property will be deemed to include the amount of cash or other property paid by the offeror in the tender or exchange offer with respect to such Exchange Property (in an amount determined on the basis of the rate of exchange in such tender or exchange offer or going-private transaction). In the event of a tender or exchange offer or a going-private transaction with respect to Exchange Property in which an offeree may elect to receive cash or other property, Exchange Property will be deemed to include the kind and amount of cash and other property received by offerees who elect to receive cash.

If a reorganization event (other than a spin-off event) with respect to the relevant reference shares occurs, then, on and after the effective date of such reorganization event:

If a spin-off event with respect to the relevant reference shares occurs, then, on and after the ex-dividend date for the distribution of equity securities subject to such spin-off event:

The calculation agent will be solely responsible for the determination and calculation of the Exchange Property if a reorganization event occurs, the value thereof and its effect on the initial share price of the relevant reference shares, the final share price and the share adjustment factor. The calculation agent's determinations and calculations, and its adjustments of the prices of the reference shares and the share adjustment factor, will be conclusive absent manifest error.

If an ADS serving as the relevant reference shares (the "original reference shares") is no longer listed or admitted to trading on a U.S. securities exchange registered under the Exchange Act, or included in the OTC Bulletin Board, or if the ADS facility between the issuer of the applicable underlying equity security and the ADS depositary is terminated for any reason, then, on and after the date such ADS is no longer so listed or admitted to trading or the date of such termination, as applicable (the "change date"), the calculation agent, in its sole discretion without consideration for the interests of investors, will either (A) determine the successor reference shares (as defined below) to such ADS after the close of the principal trading session on the trading day immediately prior to the change date in accordance with the following paragraph (each successor stock as so determined, the "successor reference shares" and such successor equity security issuer, a "successor reference share issuer") or (B) select the applicable underlying equity security to replace such reference shares.

The "successor reference shares" with respect to an ADS will be the ADS of a company selected by the calculation agent from among the ADSs of three companies organized in, or with its principal executive office located in, the country in which the reference share issuer of such original reference shares is organized, or has its principal executive office, and that are then registered to trade on the NYSE or The NASDAQ Stock Market with the same primary Standard Industrial Classification Code ("SIC Code") as such original reference shares that, in the sole discretion of the calculation agent, is the most comparable to such original reference shares, taking into account such factors as the calculation agent deems relevant, including, without limitation, market capitalization, dividend history and stock price volatility; provided, however, that the successor reference shares will not be any ADS that is (or the underlying equity security for which is) subject to a trading restriction under the trading restriction policies of Credit Suisse or any of its affiliates that would materially limit the ability of Credit Suisse or any of its affiliates to hedge the securities with respect to such ADS (a "Hedging Restriction"); provided further that if the successor reference shares cannot be identified as set forth above for which a Hedging Restriction does not exist, such successor reference shares will be selected by the calculation agent and will be the ADS of a company that (i) is organized in, or with its principal executive office located in, the country in which the issuer of such original reference shares is organized, or has its principal executive office, (ii) is then registered to trade on the NYSE or The NASDAQ Stock Market, (iii) in the sole discretion of the calculation agent, is the most comparable to such original reference shares, taking into account such factors as the calculation agent deems relevant, including, without limitation, market capitalization, dividend history and stock price volatility, (iv) is within the same Division and Major Group classification (as defined by the Office of Management and Budget) as the primary SIC Code for such original reference shares and (v) is not subject to a Hedging Restriction. Notwithstanding the foregoing, if the successor reference shares cannot be identified in the country in which the issuer of such original reference shares is organized, or has its principal executive office, as set forth above, such successor reference shares will be selected by the calculation agent and

will be a equity security of a company that is then registered to trade on the NYSE or The NASDAQ Stock Market with the same primary SIC Code as such original reference shares that in the sole discretion of the calculation agent, is the most comparable to such original reference shares, taking into account such factors as the calculation agent deems relevant including, without limitation, market capitalization, dividend history and stock price volatility and that is not subject to a Hedging Restriction.

Upon the determination by the calculation agent of any successor reference shares pursuant to clause (A) of the first paragraph under "—Delisting of ADSs or termination of ADS facility," on and after the change date, references in this product supplement or the relevant pricing supplement to such "reference shares" will no longer be deemed to refer to the original reference shares and will be deemed instead to refer to any such successor reference shares for all purposes, and references in this product supplement or the relevant pricing supplement to "reference share issuer" of the original reference shares will be deemed to be to any such successor reference share issuer. Upon the selection of any successor reference shares by the calculation agent pursuant to clause (A) of the first paragraph under "—Delisting of ADSs or termination of ADS facility," on and after the change date, (i) the initial share price for such successor reference shares will be equal to the initial share price of the original reference shares, (ii) or securities linked to a single reference share, the final share price for such successor reference shares will be the closing price of one share of such successor reference shares on the valuation date or the arithmetic average of the closing prices of one share of such successor reference shares, in each case times the share adjustment factor on such date, provided that, for securities with valuation dates, if an adjustment to the share adjustment factor for such successor reference shares would have become effective in accordance with "—Anti-dilution adjustments" above after the first valuation date but on or prior to the final valuation date, the share adjustment factor for such successor reference shares will be so adjusted for the event giving rise to such adjustment effective date only on the valuation dates occurring on or after such adjustment effective date, and (iii) the share adjustment factor for such successor reference shares will be an amount as determined by the calculation agent in good faith as of the change date, taking into account, among other things, the closing price of the original reference shares on the trading day immediately preceding the change date, subject to adjustment for certain corporate events related to such successor reference shares in accordance with "—Anti-dilution adjustments."

Following the selection of the successor reference shares, the share adjustment factor of the successor reference shares will be subject to adjustment as described above under "—Anti-dilution adjustments."

If the successor reference shares are selected, we will, or will cause the calculation agent to, provide written notice to the trustee, to us and to DTC within thirty business days immediately following the change date, of the successor reference share issuer, the successor reference shares and the initial share price for such successor reference shares, as well as the original reference shares so replaced. We expect that such notice will be passed on to you, as a beneficial owner of the securities, in accordance with the standard rules and procedures of DTC and its direct and indirect participants.

If the calculation agent selects the applicable underlying equity security to replace the reference shares pursuant to clause (B) of the first paragraph under "—Delisting of ADSs or termination of ADS facility" above, the share adjustment factor for such reference shares will thereafter equal the last value of the share adjustment factor for the ADS multiplied by the number of the applicable underlying equity securities represented by a single ADS, subject to further adjustments as described under "—Anti-dilution adjustments." The final share price for such reference shares will be expressed in U.S. dollars, converting the closing price of the applicable underlying equity security on the final valuation date into U.S. dollars using the applicable exchange rate as described below.

On any date of determination, the applicable exchange rate will be the spot rate of the local currency of the applicable underlying equity security relative to the U.S. dollar as reported by Reuters Group PLC ("Reuters") on the relevant page for such rate at approximately the closing time of the relevant exchange for the applicable underlying equity security on such day. However, (1) if such rate is not displayed on the relevant Reuters page on such date of determination, the applicable exchange rate on such day will equal an average (mean) of the bid quotations in The City of New York received by the calculation agent at approximately 11:00 a.m., New York City time, on the business day immediately following the date of determination, from three recognized foreign exchange dealers (provided that each such dealer commits to execute a contract at its applicable bid quotation) or, (2) if the calculation agent is unable to obtain three such bid quotations, the average of such bid quotations obtained from two recognized foreign exchange dealers or, (3) if the calculation agent is able to obtain such bid quotation from only one recognized foreign exchange dealer, such bid quotation, in each case for the purchase of the applicable foreign currency for U.S. dollars in the aggregate principal amount of the securities for settlement on the third business day following the date of determination. If the calculation agent is unable to obtain at least one such bid quotation, the calculation agent will determine the applicable exchange rate in its sole discretion.

If the shares of a fund are subject to a share split or reverse share split, then once such split has become effective, the share adjustment factor, which will initially be set at 1.0, will be adjusted so that the new share adjustment factor equals the product of:

If a fund is subject to a (i) share dividend, i.e., an issuance of additional shares of the fund that is given ratably to all or substantially all holders of shares of the fund or (ii) distribution of shares of the fund as a result of the triggering of any provision of the corporate charter of the fund, then, once the dividend or distribution has become effective and the shares of the fund are trading ex-dividend, the share adjustment factor will be adjusted so that the new share adjustment factor equals the prior share adjustment factor plus the product of:

If a fund distributes shares of capital stock, evidences of indebtedness or other assets or property of the fund to all or substantially all holders of shares of the fund (other than (i) share dividends or distributions referred to under "—Share dividends or distributions" above and (ii) cash dividends referred to under "—Extraordinary cash dividends or distributions" below), then, once the distribution has become effective and the shares of the fund are trading ex-dividend, the share adjustment factor will be adjusted so that the new share adjustment factor equals the product of:

The "current market price" of a fund means the arithmetic average of the closing levels of one share of the fund for the ten exchange business days prior to the exchange business day immediately preceding the ex-dividend date of the distribution requiring an adjustment to the share adjustment factor.

"Ex-dividend date" means the first trading day on which transactions in the shares of a fund trade on the relevant exchange without the right to receive that cash dividend or other cash distribution.

The "fair market value" of any such distribution means the value of such distribution on the ex-dividend date for such distribution, as determined by the calculation agent. If such distribution consists of property traded on the ex-dividend date on a U.S. national securities exchange, the fair market value will equal the closing price of such distributed property on such ex-dividend date.

A dividend or other distribution consisting exclusively of cash to all or substantially all holders of shares of a fund will be deemed to be an extraordinary cash dividend if its per share value exceeds that of the immediately preceding non-extraordinary cash dividend, if any, for the fund by an amount equal to at least 10% of the closing price of the fund on the first trading day immediately preceding the ex-dividend date, unless otherwise specified in the applicable pricing supplement.

If an extraordinary cash dividend occurs, the share adjustment factor will be adjusted so that the new share adjustment factor equals the product of:

In case an event of default (as defined in the accompanying prospectus) with respect to any securities shall have occurred and be continuing, the amount declared due and payable upon any acceleration of the securities (in accordance with the acceleration provisions set forth in the accompanying prospectus) will be determined by the calculation agent and will equal, for each security, the arithmetic average, as determined by the calculation agent, of the fair market value of the securities as determined by at least three but not more than five broker-dealers (which may include CSSU or any of our other subsidiaries or affiliates) as will make such fair market value determinations available to the calculation agent.

We may at any time purchase any securities, which may, in our sole discretion, be held, sold or cancelled.

If we purchase any securities and surrender the securities to the trustee for cancellation, the trustee will cancel them.

We will issue the securities in the form of one or more fully registered global securities, or the global notes, in denominations of $1,000 or integral multiples of $1,000 greater than $1,000 or such other denominations specified in the applicable pricing supplement. We will deposit the notes with, or on behalf of, The Depository Trust Company, New York, New York, or DTC, as the depositary, and will register the notes in the name of Cede & Co., DTC's nominee. Your beneficial interests in the global notes will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct and indirect participants in DTC. Except as set forth below, the global notes may be transferred, in whole and not in part, only to another nominee of DTC or to a successor of DTC or its nominee.

As long as the securities are represented by the global notes, we will pay the redemption amount on the securities, if any, to or as directed by DTC as the registered holder of the global notes. Payments to DTC will be in immediately available funds by wire transfer. DTC will credit the relevant accounts of their participants on the applicable date.

For a further description of procedures regarding global securities representing book-entry securities, we refer you to "Description of Debt Securities—Book-Entry System" in the accompanying prospectus and "Description of Notes—Book-Entry, Delivery and Form" in the accompanying prospectus supplement.

We may from time to time, without notice to or the consent of the registered holders of the securities, create and issue further securities ranking on an equal basis with the securities being offered hereby in all respects. Such further securities will be consolidated and form a single series with the securities being offered hereby and will have the same terms as to status, redemption or otherwise as the securities being offered hereby.

Notices to holders of the securities will be made by first class mail, postage prepaid, to the registered holders.

If applicable, the reference shares to which the securities are linked will be specified in the applicable pricing supplement. In the relevant pricing supplement, we will provide summary information regarding the business of the reference share issuer based on its publicly available documents. We take no responsibility for the accuracy or completeness of such information.

Companies with securities registered under the Exchange Act are required to file periodically certain financial and other information specified by the SEC. Information provided to or filed with the SEC can be inspected and copied at the public reference facilities maintained by the SEC at 100 F Street, NE, Washington, DC 20549, and copies of such materials can be obtained from the Public Reference Section of the SEC, 100 F Street, NE, Washington, DC 20549, at prescribed rates. In addition, information provided to or filed with the SEC electronically can be accessed through a website maintained by the SEC. The address of the SEC's website is http://www.sec.gov. Information regarding the issuer of the reference shares may also be obtained from other sources including, but not limited to, press releases, newspaper articles and other publicly disseminated documents. This URL is provided for informational purposes only and is not incorporated by referenced into this product supplement.

This product supplement and the relevant pricing supplement relate only to the securities offered thereby and do not relate to the reference shares or other securities of the reference share issuers. We have derived any and all disclosures contained in this product supplement and the relevant pricing supplement regarding the reference share issuers from the publicly available documents described above. In connection with the offering of the securities, we have not participated in the preparation of such documents or made any due diligence inquiry with respect to the reference share issuers. We do not make any representation that such publicly available documents are, or any other publicly available information regarding the reference share issuers is, accurate or complete. Furthermore, we cannot give any assurance that all events occurring prior to the date hereof (including events that would affect the accuracy or completeness of the publicly available documents described in the preceding paragraph) that would affect the trading prices of the reference shares (and therefore the final share prices) have been publicly disclosed. Subsequent disclosure of any such events or the disclosure of or failure to disclose material future events concerning the reference share issuers could affect the payment at maturity with respect to the securities and therefore the trading prices of the securities.

Neither we nor any of our affiliates makes any representation to you as to the performance of the reference shares.

We and/or our affiliates may currently or from time to time engage in business with the reference share issuers, including extending loans to, or making equity investments in, such issuers or providing advisory services to such issuers, including merger and acquisition advisory services. In the course of such business, we and/or our affiliates may acquire non-public information with respect to the reference shares or the reference share issuers, and neither we nor any of our affiliates undertakes to disclose any such information to you. In addition, one or more of our affiliates may publish research reports with respect to the reference shares or reference share issuers, and these reports may or may not recommend that investors buy or hold the reference shares. As a prospective purchaser in the securities, you should undertake an independent investigation of the reference shares and reference share issuers as in your judgment is appropriate to make an informed decision with respect to an investment in the securities.

If specified in the applicable pricing supplement, the securities may be Select Method Reverse Convertible Securities. The reference shares for any issue of Select Method Reverse Convertible Securities will be selected by Credit Suisse based on the application of a rules-based methodology (the "HOLT scoring methodology") for scoring stocks to the companies comprising the S&P 500® Index and the S&P Latin America 40 Index as of the date of the applicable pricing supplement. The HOLT scoring methodology assigns a score to each company for several variables in the three categories (corporate performance, momentum and valuation), which are then weighted to give an overall score per company. The reference shares specified in the applicable pricing supplement will be shares of a company with one of the highest HOLT scores according to the HOLT scoring methodology.

HOLT is a service of Credit Suisse. The HOLT scoring methodology attempts to identify stocks that satisfy corporate performance, momentum and valuation characteristics measured objectively by converting a company's accounting data into cash flows. This allows comparisons among companies across sectors, regions and over time. HOLT's proprietary database includes over 18,000 companies in more than 55 countries. The HOLT scoring methodology is not intended to predict the future market or financial performance of any company (either in absolute terms or relative to other companies) nor is the ranking of the companies intended to serve as a qualitative ordering of the companies.

HOLT is a trademark of Credit Suisse or its affiliates in the United States and other countries.

If specified in the applicable pricing supplement, the securities may be Z Series Reverse Convertible Securities. The reference shares for any issue of Z Series Convertible Securities will be chosen by Credit Suisse from among those selected by Zacks Investment Research in accordance with Zacks' proprietary selection methodology.

Zacks selects reference shares for each issuance of Z Series Reverse Convertibles Securities using a proprietary quantitative investment strategy for security selection that attempts to identify stocks and ADSs whose returns it anticipates will outperform the returns generated by stocks and ADSs in the broad U.S. market. Zacks maintains a database of over 8,300 North American stocks and ADSs listed on U.S.-based exchanges and applies its selection methodology to the approximately 4,500 to 5,000 stocks and ADSs in this database that have reported earnings estimates. Zacks' selection methodology utilizes multi-factor proprietary selection rules to identify those stocks and ADSs that offer the greatest potential to generate returns commensurate with the anticipated levels of risk associated with these stocks and ADSs. The Z Series selection rules combine several variables such as liquidity, relative valuation and company efficiency, as well as other factors such as the availability of options on and the presence of sufficient implied volatility of the stocks and ADSs, to enhance the investment applications and investment utility of such stocks and ADSs. The Z Series selection methodology is not intended to predict the future market or financial performance of any company.

Founded in 1978, Zacks Investment Research has more than 25 years of experience in providing institutional and individual investors with the analytical tools and financial information necessary to the success of their investment process. Today, Zacks' models process over 25,000 earnings estimate revisions and changes in broker recommendations weekly from over 200 brokerage firms, produced by more than 3,500 analysts.

If applicable, the fund shares and the fund to which the securities are linked will be specified in the applicable pricing supplement.

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:

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.

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 the securities. Under one approach, each security should be treated as consisting of, (a) a put option (the

"Put Option") that requires the holder to purchase the reference shares from us for an amount equal to the Deposit (as defined below) if the closing price of the reference shares is not greater than the knock-in level on the valuation date, and (b) a deposit with us of cash, in an amount equal to the principal amount of a security (the "Deposit") to secure the holder's potential obligation to purchase the reference shares. We and by acceptance of a security, each holder, agree to treat the securities as consisting of a Deposit and a Put Option with respect to the reference shares for all U.S. federal income tax purposes. The balance of this summary assumes that the securities are 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 "contingent payment debt instruments" that are subject to special tax rules governing the recognition of income over the term of your securities. If the securities were to be treated as contingent debt, 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 amount of interest that you would be required to include in income on a current basis would not be matched by cash distributions to you. You would recognize gain or loss upon the sale, redemption or maturity of your securities in an amount equal to the difference, if any, between the amount you receive at such time and your adjusted basis in your securities. In general, your adjusted basis in your securities would be equal to the amount you paid for your securities, increased by the amount of interest you previously accrued with respect to your securities. Any gain you recognized upon the sale, redemption, or maturity of your securities would be ordinary income and any loss to the extent of interest you included in income in the current or previous taxable years in respect of your securities would be ordinary loss, and thereafter would be capital loss.

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.

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 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, a portion of each stated interest coupon on the securities should be treated as interest on the Deposit, and the balance should be treated as put premium received by the U.S. Holder in respect of the Put Option to us (the "Put Premium"). The applicable pricing supplement will specify the amount of the stated interest coupon on the securities that constitutes interest on the Deposit.

We will treat the Deposit as a debt obligation issued by us. Accordingly, we will treat each coupon payment as consisting of interest on the Deposit in the amount specified in the applicable pricing supplement and the balance as Put Premium paid to you. U.S. Holders should therefore include the interest component of the coupon in income as received or accrued, based on their method of accounting.

If the Put Option expires unexercised (i.e., 100% of the principal amount of a security is repaid in cash upon maturity of the security), the U.S. Holder should recognize the total Put Premium received as short-term capital gain at such time.

If the Put Option is exercised (i.e., reference shares are delivered upon maturity of the security), the U.S. Holder should not recognize any gain or loss with respect to the Put Option (other than with respect to cash received in lieu of fractional shares, as described below). The U.S. Holder should have an adjusted tax basis in all reference shares received (including for this purpose any fractional shares) equal to the Deposit less the total Put Premium received. The U.S. Holder's holding period for any reference shares received should start on the day after the delivery of the reference shares. The U.S. Holder should generally recognize short-term capital gain or loss with respect to cash received in lieu of fractional shares in an amount equal to the difference between the amount of such cash received and the U.S. Holder's basis in the fractional shares, which should be equal to the U.S. Holder's basis in all of the reference shares (including the fractional shares), multiplied by a fraction, the numerator of which is the fractional shares and the denominator of which is all of the reference shares (including fractional shares).

Upon a sale or exchange of a security, a U.S. Holder should allocate the sale proceeds received between the Deposit and the Put Option on the basis of their respective fair market values on the date of sale. The U.S. Holder should generally recognize gain or loss with respect to the Deposit in an amount equal to the difference between the amount of the sale proceeds allocable to the Deposit and the U.S. Holder's adjusted tax basis in the Deposit (which will generally equal the issue 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 will be short-term capital gain or loss if the U.S. Holder has held the security for not more than one year, and long-term capital gain or loss if the U.S. Holder has held the security for more than one year. A U.S. Holder should recognize short-term capital gain equal to the amount of remaining sale proceeds allocable to the Put Option plus any previously received Put 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 Put Option. 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 Put Premium previously received and the amount of the payment deemed made by the U.S. Holder to the buyer with respect to the assumption of the Put Option. The amount of the deemed payment will be added to the sale proceeds allocated to the Deposit in determining the gain or loss in respect of the Deposit.

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 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 (a "Non-U.S. Holder"), 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 (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.

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.

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.

On December 19, 2007, Representative Richard Neal introduced a tax bill (the "Bill") that was referred to the House Ways and Means Committee of the previous Congress and would apply to "prepaid derivative contracts" acquired after the date of enactment of the Bill. No further action was taken on the Bill and it has not been reintroduced in the current Congress. The Bill, if reintroduced with the same language, would apply to certain derivative financial contracts with a term of more than one year, where there is no substantial likelihood that the taxpayer will be required to pay any additional amount thereunder, and would require the holder of such a contract to include as interest income each year in respect of such contract an amount determined by reference to the monthly U.S. federal short-term rate determined under Code section 1274(d). A holder's tax basis in such contract would be increased by the amount so included. Any gain (either at maturity or upon sale) with respect to the contract would be treated as long-term capital gain if the contract is a capital asset in the hands of the holder and such holder has held the contract for more than one year. Any loss would be treated as ordinary loss to the extent of prior interest accruals.

While the Bill, if reintroduced with the same language and enacted, would not apply to the securities (due to its prospective effective date), it is not possible to predict whether any tax legislation that may ultimately be enacted will apply to your securities (possibly on a retroactive basis). You are urged to consult your tax adviser regarding the Bill and any future tax legislation that may apply to your securities.

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.

The Employee Retirement Income Security Act of 1974, as amended ("ERISA"), and Section 4975 of the Internal Revenue Code of 1986, (the "Code"), impose certain requirements on (a) employee benefit plans subject to Title I of ERISA, (b) individual retirement accounts, Keogh plans or other arrangements subject to Section 4975 of the Code, (c) entities whose underlying assets include "plan assets" by reason of any such plan's or arrangement's investment therein (we refer to the foregoing collectively as "Plans") and (d) persons who are fiduciaries with respect to Plans. In addition, certain governmental, church and non-U.S. plans ("Non-ERISA Arrangements") are not subject to Section 406 of ERISA or Section 4975 of the Code, but may be subject to other laws that are substantially similar to those provisions (each, a "Similar Law").

In addition to ERISA's general fiduciary standards, Section 406 of ERISA and Section 4975 of the Code prohibit certain transactions involving the assets of a Plan and persons who have specified relationships to the Plan, i.e., "parties in interest" as defined in ERISA or "disqualified persons" as defined in Section 4975 of the Code (we refer to the foregoing collectively as "parties in interest") unless exemptive relief is available under an exemption issued by the U.S. Department of Labor. Parties in interest that engage in a non-exempt prohibited transaction may be subject to excise taxes and other penalties and liabilities under ERISA and Section 4975 of the Code. We, and our current and future affiliates, including CSSU and the calculation agent, may be parties in interest with respect to many Plans. Thus, a Plan fiduciary considering an investment in securities should also consider whether such an investment might constitute or give rise to a prohibited transaction under ERISA or Section 4975 of the Code. For example, the securities may be deemed to represent a direct or indirect sale of property, extension of credit or furnishing of services between us and an investing Plan which would be prohibited if we are a party in interest with respect to the Plan unless exemptive relief were available under an applicable exemption.

In this regard, each prospective purchaser that is, or is acting on behalf of, a Plan, and proposes to purchase securities, should consider the exemptive relief available under the following prohibited transaction class exemptions, or PTCEs: (A) the in-house asset manager exemption (PTCE 96-23), (B) the insurance company general account exemption (PTCE 95-60), (C) the bank collective investment fund exemption (PTCE 91-38), (D) the insurance company pooled separate account exemption (PTCE 90-1) and (E) the qualified professional asset manager exemption (PTCE 84-14). In addition, ERISA Section 408(b)(17) and Section 4975(d)(20) of the Code provide a limited exemption for the purchase and sale of securities and related lending transactions, provided that neither the issuer of the securities nor any of its affiliates have or exercise any discretionary authority or control or render any investment advice with respect to the assets of any Plan involved in the transaction and provided further that the Plan pays no more than adequate consideration in connection with the transaction (the so-called "service provider exemption"). There can be no assurance that any of these statutory or class exemptions will be available with respect to transactions involving the securities.

Each purchaser or holder of a security, and each fiduciary who causes any entity to purchase or hold a security, shall be deemed to have represented and warranted, on each day such purchaser or holder holds such securities, that either (i) it is neither a Plan nor a Non-ERISA Arrangement and it is not purchasing or holding securities on behalf of or with the assets of any Plan or Non-ERISA arrangement; or (ii) its purchase, holding and subsequent disposition of such securities shall not constitute or result in a non-exempt prohibited transaction under Section 406 of ERISA, Section 4975 of the Code or any provision of Similar Law.

Fiduciaries of any Plans and Non-ERISA Arrangements should consult their own legal counsel before purchasing the securities. We also refer you to the portions of the prospectus addressing restrictions applicable under ERISA, the Code and Similar Law.

Each purchaser of a security will have exclusive responsibility for ensuring that its purchase, holding and subsequent deposition of the security does not violate the fiduciary or prohibited transaction rules of ERISA, the Code or any Similar Law. Nothing herein shall be construed as a representation that an investment in the securities would meet any or all of the relevant legal requirements with respect to investments by, or is appropriate for, Plans or Non-ERISA Arrangements generally or any particular Plan or Non-ERISA Arrangement.

Unless otherwise specified in the applicable pricing supplement, we will sell the securities to CSSU, acting as principal, at the discounts or concessions set forth in the applicable pricing supplement, for resale to one or more investors or other purchasers at the offering prices specified in the applicable pricing supplement. CSSU may offer the securities it has purchased as principal to other dealers. CSSU may sell securities to any dealer at a discount and, unless otherwise specified in the applicable pricing supplement, the discount allowed to any dealer will not be in excess of the discount to be received by CSSU from us. After the initial public offering of any securities, the public offering price, concession and discount of such securities may be changed.

Each issue of securities will be a new issue of securities with no established trading market. Unless otherwise specified in the applicable pricing supplement, CSSU intends to make a secondary market in the securities. Any of our broker-dealer subsidiaries or affiliates, including CSSU, may use the pricing supplement, together with this product supplement and the accompanying prospectus supplement and prospectus, in connection with the offers and sales of securities related to market-making transactions by and through our broker-dealer subsidiaries or affiliates, including CSSU, at negotiated prices related to prevailing market prices at the time of sale or otherwise. Any of our broker-dealer subsidiaries or affiliates, including CSSU, may act as principal or agent in such transactions. None of our broker-dealer subsidiaries or affiliates, including CSSU, has any obligation to make a market in the securities and any broker-dealer subsidiary or affiliate that does make a market in the securities may discontinue any market-making activities at any time without notice, at its sole discretion. No assurance can be given as to the liquidity of the trading market for the securities. Unless otherwise specified in the applicable pricing supplement, the securities will not be listed on a national securities exchange in the United States.

We reserve the right to withdraw, cancel or modify the offer made hereby without notice.

We own, directly or indirectly, all of the outstanding equity securities of CSSU. The net proceeds received from the sale of the securities will be used, in part, by CSSU or one of its affiliates in connection with hedging our obligations under the securities. The underwriting arrangements for any offering in which our affiliates participate will comply with the requirements of NASD Rule 2720 of the Financial Industry Regulatory Authority, Inc., which is commonly referred to as FINRA, regarding a FINRA member firm's distribution of the securities of an affiliate and related conflicts of interest. In accordance with NASD Rule 2720, CSSU or any of our other affiliates may not make sales in offerings of the securities to any of its discretionary accounts without the prior written approval of the customer.

We have agreed to indemnify CSSU against liabilities under the U.S. Securities Act of 1933, as amended, or contribute to payments that CSSU may be required to make in that respect. We have also agreed to reimburse CSSU for expenses.

In connection with the offering, CSSU may engage in stabilizing transactions and over-allotment transactions in accordance with Regulation M under the Exchange Act.

These stabilizing transactions may have the effect of raising or maintaining the market prices of the securities or preventing or retarding a decline in the market prices of the securities. As a result, the prices of the securities may be higher than the prices that might otherwise exist in the open market.

CSSU and its affiliates have engaged and may in the future engage in commercial banking and investment banking and other transactions with us and our affiliates in the ordinary course of business.

In the United States, the securities may be offered for sale in those jurisdictions where it is lawful to make such offers.

CSSU has represented and agreed that it has not offered, sold or delivered and will not offer, sell or deliver any of the securities directly or indirectly, or distribute any pricing supplement or this product supplement or the accompanying prospectus supplement or prospectus or any other offering material relating to the securities, in or from any jurisdiction except under circumstances that will result in compliance with the applicable laws and regulations thereof and that it will not impose any obligations on us.

No action has been or will be taken by us or CSSU that would permit a public offering of the securities or possession or distribution of the relevant underlying supplement, if applicable, this product supplement and the accompanying prospectus supplement and prospectus or any pricing supplement in any jurisdiction other than the United States.

Concurrently with the offering of the securities as described in this product supplement, we may issue other securities from time to time as described in the accompanying prospectus supplement and prospectus.

The securities are not and will not be authorized by the Argentine Comisión Nacional de Valores for public offering in Argentina and may thus not be offered or sold to the public at large or to sectors or specific groups thereof by any means, including but not limited to personal offerings, written materials, advertisements or the media, in circumstances which constitute a public offering of securities under Argentine Law No. 17,811, as amended.

This is a private offering. The securities have not been, and will not be, registered with the Central Bank of Uruguay for public offer in Uruguay.

Each purchaser of the securities will be required to represent and agree that it has not offered or sold, and will not offer or sell, any securities in Brazil, except in circumstances which do not constitute a public offering or distribution under Brazilian laws and regulations. The securities have not been and will not be registered with the Brazilian Securities Commission (Comissão de Valores Mobiliários—CVM).

The securities have not been, and will not be, registered with the National Registry of Securities maintained by the Mexican National Banking and Securities Commission nor with the Mexican Stock Exchange and may not be offered or sold publicly in the United Mexican States. This product supplement and the accompanying pricing supplement, prospectus supplement and prospectus may not be publicly distributed in the United Mexican States.

NEITHER THE ISSUER NOR THE SECURITIES HAVE BEEN REGISTERED WITH THE SUPERINTENDENCIA DE VALORES Y SEGUROS PURSUANT TO LAW NO. 18.045, THE LEY DE MERCADO DE VALORES, AND REGULATIONS THEREUNDER. THIS PRODUCT SUPPLEMENT AND THE ACCOMPANYING PRICING SUPPLEMENT, PROSPECTUS SUPPLEMENT AND PROSPECTUS DO NOT CONSTITUTE AN OFFER OF, OR AN INVITATION TO SUBSCRIBE FOR OR PURCHASE, THE SECURITIES IN THE REPUBLIC OF CHILE, OTHER THAN TO INDIVIDUALLY IDENTIFIED BUYERS PURSUANT TO A PRIVATE OFFERING WITHIN THE MEANING OF ARTICLE 4 OF THE LEY DE MERCADO DE VALORES (AN OFFER THAT IS NOT "ADDRESSED TO THE PUBLIC AT LARGE OR TO A CERTAIN SECTOR OR SPECIFIC GROUP OF THE PUBLIC").

In relation to each member state of the European Economic Area that has implemented the Prospectus Directive (each, a relevant member state), with effect from and including the date on which the Prospectus Directive is implemented in that relevant member state (the relevant implementation date), an offer of securities described in this product supplement may not be made to the public in that relevant member state prior to the publication of a prospectus in relation to the securities that has been approved by the competent authority in that relevant member state or, where appropriate, approved in another relevant member state and notified to the competent authority in that relevant member state, all in accordance with the Prospectus Directive, except that, with effect from and

including the relevant implementation date, an offer of securities may be offered to the public in that relevant member state at any time:

Each purchaser of securities described in this product supplement located within a relevant member state will be deemed to have represented, acknowledged and agreed that it is a "qualified investor" within the meaning of Article 2(1)(e) of the Prospectus Directive.

For purposes of this provision, the expression an "offer to the public" in any relevant member state means the communication in any form and by any means of sufficient information on the terms of the offer and the securities to be offered so as to enable an investor to decide to purchase or subscribe the securities, as the expression may be varied in that member state by any measure implementing the Prospectus Directive in that member state, and the expression "Prospectus Directive" means Directive 2003/71/EC and includes any relevant implementing measure in each relevant member state.

The sellers of the securities have not authorized and do not authorize the making of any offer of securities through any financial intermediary on their behalf, other than offers made by the underwriters with a view to the final placement of the securities as contemplated in this product supplement. Accordingly, no purchaser of the securities, other than the underwriters, is authorized to make any further offer of the securities on behalf of the sellers or the underwriters.
