We are not affiliated with the Reference Share Issuer. We assume no responsibility for the adequacy of the information about the Reference Share Issuer contained in the applicable pricing supplement. You should make your own investigation into the Reference Shares and the Reference Share Issuer. We are not responsible for the Reference Share Issuer’s public disclosure of information, whether contained in SEC filings or otherwise.

While the notes are outstanding, we or any of our affiliates may carry out hedging activities related to the notes, including in the Reference Shares or instruments related to the Reference Shares. We or our affiliates may also trade in the Reference Shares or instruments related to the Reference Shares from time to time. Any of these hedging or trading activities as of the Pricing Date and during the term of the notes could adversely affect our payment to you at maturity.

We and our affiliates play a variety of roles in connection with the issuance of the notes, including acting as calculation agent, hedging our obligations under the notes and determining their estimated value. In performing these duties, the economic interests of us and our affiliates are potentially adverse to your interests as an investor in the notes. Further, hedging activities may adversely affect any payment on or the value of the notes. Any profit in connection with such hedging activities will be in addition to any other compensation that we and our affiliates receive for the sale of the notes, which creates an additional incentive to sell the notes to you. We and/or our affiliates may also currently or from time to time engage in business with the Reference Share Issuer, including extending loans to, or making equity investments in, the Reference Share Issuer or providing advisory services to the Reference Share Issuer. In addition, one or more of our affiliates may publish research reports or otherwise express opinions with respect to the Reference Share Issuer and these reports may or may not recommend that investors buy or hold the Reference Shares. As a prospective purchaser of the notes, you should undertake an independent investigation of the Reference Share Issuer that in your judgment is appropriate to make an informed decision with respect to an investment in the notes.

In addition to the price of the Reference Shares on any day, the value of the notes will be affected by a number of economic and market factors that may either offset or magnify each other, including the actual and expected volatility of the Reference Shares, the time to maturity of the notes, the Automatic Redemption feature (which would limit the value of the notes), the dividend rate on the Reference Shares, interest and yield rates in the market generally, investors’ expectations with respect to the rate of inflation, events affecting companies engaged in the oil and natural gas industries, geopolitical conditions and a variety of economic, financial, political, regulatory and judicial events that affect the Reference Shares, and our creditworthiness, including actual or anticipated downgrades in our credit ratings. Some or all of these factors may influence the price that you will receive if you choose to sell your notes prior to maturity. The impact of any of the factors set forth above may enhance or offset some or all of any change resulting from another factor or factors.

Your return on the notes will not reflect the return you would realize if you actually owned the Reference Shares. The return on your investment, which is based on the percentage change in the Reference Shares, is not the same as the total return based on a purchase of the Reference Shares.

As a holder of the notes, you will not have voting rights or rights to receive cash dividends or other distributions or other rights with respect to the Reference Shares. In addition, the Reference Share Issuer will not have any obligation to consider your interests as a holder of the notes in taking any corporate action that might affect the value of the Reference Shares, and therefore, the value of the notes.

The calculation agent will make anti-dilution adjustments for certain events affecting the Reference Shares. However, an adjustment will not be required in response to all events that could affect the Reference Shares. If an event occurs that does not require the calculation agent to make an adjustment, or if an adjustment is made but such adjustment does not fully reflect the economics of such event, the value of the notes may be materially and adversely affected. See “Description of the Securities—Adjustments—For equity securities of a reference share issuer” in the accompanying product supplement.

* Credit Suisse may act through its Nassau Branch or its London Branch.

** In the event that the closing price for the Reference Shares is not available on the Pricing Date, the Initial Share Price will be determined on the immediately following trading day on which a closing price is available.

† Subject to postponement as described in the applicable pricing supplement and product supplement.

The risks set forth in the section entitled “Product Risks” above are only intended as summaries of some of the risks relating to an investment in the notes. Prior to investing in the notes, you should, in particular, review the “Product Risks” above, the “Selected Risk Considerations” section in the applicable pricing supplement and the “Risk Factors” section of the product supplement, which set forth risks relating to an investment in the notes.

You may revoke your offer to purchase the notes at any time prior to the time at which we accept such offer on the date the notes are priced. We reserve the right to change the terms of, or reject any offer to purchase the notes prior to their issuance. In the event of any changes to the terms of the notes, we will notify you and you will be asked to accept such changes in connection with your purchase. You may also choose to reject such changes in which case we may reject your offer to purchase.
