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:

· Depending on the performance of the Underlying Stock as measured shortly before the maturity date, 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.

· Your investment return is limited to the return represented by the periodic interest payments over the term of the notes and the Step Payment, if any, and may be less than a comparable investment directly in the Underlying Stock.

· 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.

· You will have no rights of a holder of the Underlying Stock, and you will not be entitled to receive any shares of the Underlying Stock or dividends or other distributions by the Underlying Company.

· The issuer, MLPF&S and their respective affiliates do not control the Underlying Company and are not responsible for any disclosure made by the Underlying Company. The Underlying Company will have no obligations relating to the notes.
