Risk Factors

Please see the Preliminary Offering Documents for a description of certain risks related to this investment, including, but not limited to, the following:

· If your notes are not called prior to maturity, your investment may result in a loss; there is no guaranteed return of principal.

· Payments on the notes, including repayment of principal, are subject to the credit risk of HSBC. If HSBC becomes insolvent or is unable to pay its obligations, you may lose your entire investment.

· The estimated initial value of the notes on the pricing date will be less than their public offering price.

· If you attempt to sell the notes prior to maturity, their market value may be lower than both the public offering price and the estimated initial value of the notes on the pricing date.

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

· You will have no rights of a holder of the securities represented by the Market Measure, and you will not be entitled to receive securities or dividends or other distributions by the issuers of those securities.

· Your return on the notes may be affected by factors affecting the international securities markets, specifically changes within the Eurozone. The Eurozone is and has been undergoing severe financial stress and the political, legal, and regulatory ramifications are impossible to predict. Changes within the Eurozone could adversely affect the performance of the Market Measure and, consequently, the value of the notes. In addition, you will not obtain the benefit of any increase in the value of the euro against the U.S. dollar, which you would have received if you had owned the securities in the Market Measure during the term of your notes, although the level of the Market Measure may be adversely affected by general exchange rate movements in the market.

Final terms will be set on the pricing date within the given range for the specified Market-Linked Investment. Please see the Preliminary Offering Documents for complete product disclosure, including related risks and tax disclosure.
