Supplemental Information Relating to the Terms of the Notes

Notwithstanding anything contained in the accompanying prospectus supplement or product supplement to the contrary, the notes will be issued under the senior indenture dated March 31, 2009, between HSBC USA Inc., as Issuer, and Wells Fargo Bank, National Association, as trustee.  Such indenture will have substantially the same terms as the indenture described in the accompanying prospectus supplement and product supplement.  HSBC Bank USA, N.A. will act as paying agent with respect to the notes pursuant to a Paying Agent and Securities Registrar Agreement dated June 1, 2009, between HSBC USA Inc. and HSBC Bank USA, N.A.

Selected Purchase Considerations

· APPRECIATION POTENTIAL — The notes provide the opportunity to participate in the appreciation of the reference asset at maturity. If a knock-out event has not occurred, in addition to the principal amount, you will receive at maturity at least the contingent minimum return of 2.10% on the notes, or a minimum payment at maturity of  $1,021 for every $1,000 principal amount note. Even if a knock-out event has occurred, if the final level is greater than the initial level, in addition to the principal amount, you will receive at maturity a return on the notes equal to the reference return. Because the notes are our senior unsecured obligations, payment of any amount at maturity is subject to our ability to pay our obligations as they become due.

· LIMITED PROTECTION AGAINST LOSS — If a knock-out event has occurred, you will lose 1.00% of the principal amount for every 1.00% decline of the level of the reference asset during the observation period.  If a knock-out event has occurred and the reference return is -100.00%, you will lose your entire investment.

· DIVERSIFICATION OF THE S&P 500® INDEX — The return on the notes is linked to the S&P 500® Index. The S&P 500® Index consists of 500 component stocks selected to provide a performance benchmark for the U.S. equity

-2-

markets. For additional information about the reference asset, see the information set forth under “Description of the Reference Asset” herein.

· TAX TREATMENT — There is no direct legal authority as to the proper tax treatment of the notes, and therefore significant aspects of the tax treatment of the notes are uncertain, as to both the timing and character of any inclusion in income in respect of the notes.  Under one approach, the notes should be treated as executory contracts with respect to the reference asset.  We intend to treat the notes consistent with this approach.  Pursuant to the terms of the notes, you agree to treat the notes under this approach for all U.S. federal income tax purposes. Notwithstanding any disclosure in the accompanying product supplement to the contrary, our special U.S. tax counsel in this transaction is Sidley Austin llp. Subject to the limitations described therein, and based on certain factual representations received from us, in the opinion of our special U.S. tax counsel, Sidley Austin llp, it is reasonable to treat the notes as executory contracts with respect to the reference asset.  Pursuant to this approach, we do not intend to report any income or gain with respect to the notes prior to their maturity or an earlier sale or exchange and we intend to treat any gain or loss upon maturity or an earlier sale or exchange as long-term capital gain or loss, provided that you have held the note for more than one year at such time for U.S. federal income tax purposes.  For a further discussion of U.S. federal income tax consequences related to the notes, see the section “Certain U.S. Federal Income Tax Considerations” in the accompanying product supplement.

Selected Risk Considerations

An investment in the notes involves significant risks. Investing in the notes is not equivalent to investing directly in the reference asset or any of the component securities of the reference asset. These risks are explained in more detail in the “Risk Factors” sections of the accompanying product supplement and prospectus supplement.

· SUITABILITY OF NOTES FOR INVESTMENT — A person should reach a decision to invest in the notes after carefully considering, with his or her advisors, the suitability of the notes in light of his or her investment objectives and the information set out in this free writing prospectus.  Neither HSBC nor any dealer participating in the offering makes any recommendation as to the suitability of the notes for investment.

· YOUR INVESTMENT IN THE NOTES MAY RESULT IN A LOSS — The notes do not guarantee any return of principal. The return on the notes at maturity is linked to the performance of the reference asset and will depend on whether a knock-out event has occurred and whether, and the extent to which, the reference return is positive or negative. If the official closing level has declined, as compared to the initial level, by more than the knock-out buffer amount of 30.00% at any time during the observation period, a knock-out event has occurred, and the protection provided by the knock-out buffer amount will terminate. IF A KNOCK-OUT EVENT OCCURS, YOU MAY LOSE UP TO 100% OF YOUR INVESTMENT.

· CREDIT RISK OF HSBC USA INC. — The notes are senior unsecured debt obligations of the issuer, HSBC, and are not, either directly or indirectly, an obligation of any third party. Any payment to be made on the notes, including any principal protection at maturity, depends on the ability of HSBC to satisfy its obligations as they come due. As a result, the actual and perceived creditworthiness of HSBC may affect the market value of the notes and, in the event HSBC were to default on its obligations, you may not receive the amounts owed to you under the terms of the notes.

· YOUR PROTECTION MAY TERMINATE AT ANY TIME DURING THE TERM OF THE NOTES — If the official closing level at any time during the observation period declines from the initial level by more than the knock-out buffer amount of 30.00%, you will at maturity be fully exposed to any decline in the level of the reference asset. We refer to this feature as a contingent buffer. Under these circumstances, if the final level is less than the initial level, you will lose 1.00% of the principal amount of your investment for every 1.00% decrease in the final level as compared to the initial level. You will be subject to this potential loss of principal even if the level of reference asset subsequently increases such that the official closing level is less than the initial level by not more than the knock-out buffer amount of 30.00%, or is equal to or greater than the initial level. As a result, you may lose some or all of your investment.  Your return on the notes may not reflect the return you would receive on a conventional fixed or floating rate debt instrument with a comparable term to maturity issued by HSBC or any other issuer with a similar credit rating.

· YOUR ABILITY TO RECEIVE THE CONTINGENT MINIMUM RETURN MAY TERMINATE AT ANY TIME DURING THE TERM OF THE NOTES — If the official closing level at any time during the observation period declines from the initial level by more than the knock-out buffer amount of 30.00%, you will not be entitled to receive the protection provided by the contingent minimum return on the notes. Under these circumstances, you may lose some or all of your investment at maturity and will be fully exposed to any decline in the level of the reference asset.

· CERTAIN BUILT-IN COSTS ARE LIKELY TO ADVERSELY AFFECT THE VALUE OF THE NOTES PRIOR TO MATURITY — While the payment at maturity described in this free writing prospectus is based on the full principal

-3-

amount of your notes, the original issue price of the notes includes the placement agent’s commission and the estimated cost of hedging our obligations under the notes through one or more of our affiliates. As a result, the price, if any, at which HSBC Securities (USA) Inc. will be willing to purchase notes from you in secondary market transactions, if at all, will likely be lower than the original issue price, and any sale of notes by you  prior to the maturity date could result in a substantial loss to you. The notes are not designed to be short-term trading instruments. Accordingly, you should be able and willing to hold your notes to maturity.

· NO INTEREST OR DIVIDEND PAYMENTS OR VOTING RIGHTS — As a holder of the notes, you will not receive interest payments, and you will not have voting rights or rights to receive cash dividends or other distributions or other rights that holders of securities composing the reference asset would have.

· LACK OF LIQUIDITY — The notes will not be listed on any securities exchange. HSBC Securities (USA) Inc. intends to offer to purchase the notes in the secondary market but is not required to do so and may cease making such offers at any time if at all. Because other dealers are not likely to make a secondary market for the notes, the price at which you may be able to trade your notes is likely to depend on the price, if any, at which HSBC Securities (USA) Inc. is willing to buy the notes. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the notes easily.

· POTENTIAL CONFLICTS — HSBC and its affiliates play a variety of roles in connection with the issuance of the notes, including acting as calculation agent and hedging its obligations under the notes. In performing these duties, the economic interests of the calculation agent and other affiliates of HSBC are potentially adverse to your interests as an investor in the notes. HSBC will not have any obligation to consider your interests as a holder of the notes in taking any corporate action that might affect the level of the reference asset and the value of the notes.

· THE NOTES ARE NOT INSURED BY ANY GOVERNMENTAL AGENCY OF THE UNITED STATES OR ANY OTHER JURISDICTION — The notes are not deposit liabilities or other obligations of a bank and are not insured by the Federal Deposit Insurance Corporation or any other governmental agency or program of the United States or any other jurisdiction.  An investment in the notes is subject to the credit risk of HSBC, and in the event that HSBC is unable to pay its obligations as they become due, you may not receive the full payment at maturity of the notes. This debt is not guaranteed under the Federal Deposit Insurance Corporation’s Temporary Liquidity Guarantee Program.

· MANY ECONOMIC AND MARKET FACTORS WILL IMPACT THE VALUE OF THE NOTES — In addition to the level of the reference asset 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 expected volatility of the reference asset;

· the time to maturity of the notes;

· whether a knock-out event has occurred;

· the dividend rate on the equity securities underlying the reference asset;

· interest and yield rates in the market generally;

· a variety of economic, financial, political, regulatory or judicial events; and

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

What Is the Total Return on the Notes at Maturity Assuming a Range of Performance for the Reference Asset?

The following table and graph illustrate the hypothetical total return at maturity on the notes. The “total return” as used in this free writing prospectus is the number, expressed as a percentage, that results from comparing the payment at maturity per $1,000 principal amount note to $1,000. The hypothetical total returns set forth below assume an initial level of 1,000.00 and reflect the knock-out buffer amount of 30.00% and the contingent minimum return on the notes of 2.10%. The hypothetical total returns set forth below are for illustrative purposes only and may not be the actual total returns applicable to a purchaser of the notes. The numbers appearing in the following table and examples have been rounded for ease of analysis.

Hypothetical Final Level	Hypothetical Reference Return	Hypothetical Total Return

(1) The official closing level has not declined, as compared to the initial level, by more than 30.00% at any time during the observation period.

(2) The official closing level has declined, as compared to the initial level, by more than 30.00% at any time during the observation period.

Hypothetical Examples of Amounts Payable at Maturity

The following examples illustrate how the total returns set forth in the table above are calculated.

Example 1: A knock-out event has not occurred, and the level of the reference asset increases from the initial level of 1,000.00 to a final level of 1,005.00. Because a knock-out event has not occurred and the reference return of 0.50% is less than the contingent minimum return of 2.10%, the investor benefits from the contingent minimum return and receives a payment at maturity of $1,021 per $1,000 principal amount note.

Example 2: A knock-out event has not occurred, and the level of the reference asset decreases from the initial level of 1,000.00 to a final level of 850.00. Because a knock-out event has not occurred and the reference return of -15.00% is less than the contingent minimum return of 2.10%, the investor benefits from the contingent minimum return and receives a payment at maturity of $1,021 per $1,000 principal amount note.

-5-

Example 3: The level of the reference asset increases from the initial level of 1,000.00 to a final level of 1,100.00. Regardless of a knock-out event occurring or not, because the reference return of 10.00% is positive and is greater than the contingent minimum return of 2.10%, the investor receives a payment at maturity of $1,100.00 per $1,000 principal amount note, calculated as follows:

$1,000 + ($1,000 × 10.00%) = $1,100.00

Example 4: A knock-out event has occurred, and the level of the reference asset decreases from the initial level of 1,000.00 to a final level of 900.00. Because a knock-out event has occurred, and the reference return is -10.00%, the investor is exposed to the negative performance of the reference asset and receives a payment at maturity of $900.00 per $1,000.00 principal amount note, calculated as follows:

$1,000 + ($1,000 × -10.00%) = $900.00

Example 5: A knock-out event has occurred, and the level of the reference asset decreases from the initial level of 1,000.00 to a final level of 600.00. Because a knock-out event has occurred, and the reference return is -40.00%, the investor is exposed to the negative performance of the reference asset and receives a payment at maturity of $600.00 per $1,000.00 principal amount note, calculated as follows:

$1,000 + ($1,000 × -40.00%) = $600.00

Description of the Reference Asset

General

This free writing prospectus is not an offer to sell and it is not an offer to buy interests in any reference asset or any of the securities comprising any reference asset or any underlying index.  All disclosures contained in this free writing prospectus regarding a reference asset, including its make-up, performance, method of calculation and changes in its components, where applicable, are derived from publicly available information. Neither HSBC nor any of its affiliates assumes any responsibilities for the adequacy or accuracy of information about any reference asset or any constituent included in any reference asset contained in this free writing prospectus.  You should make your own investigation into each reference asset.

We urge you to read the section “Sponsors or Issuers and Reference Asset” on page S-37 in the accompanying prospectus supplement.

The S&P 500® Index

We have derived all information relating to the reference asset, including, without limitation, its make-up, performance, method of calculation and changes in its components, from publicly available sources. That information reflects the policies of and is subject to change by, Standard & Poor’s, a division of The McGraw-Hill Companies, Inc. (“S&P”).  S&P is under no obligation to continue to publish, and may discontinue or suspend the publication of the reference asset at any time.

S&P publishes the reference asset.

The reference asset is a capitalization weighted index and is intended to provide an indication of the pattern of common stock price movement.  The calculation of the level of the reference asset, discussed below in further detail, is based on the relative value of the aggregate market value of the common stocks of 500 companies as of a particular time compared to the aggregate average market value of the common stocks of 500 similar companies during the base period of the years 1941 through 1943.  As of September 30, 2009, 409 companies, or 80.7% of the market capitalization of the reference asset, traded on the New York Stock Exchange (the “NYSE”) and 91 companies, or 19.3% of the market capitalization of the reference asset, traded on The Nasdaq Stock Market.  S&P chooses companies for inclusion in the reference asset with the aim of achieving a distribution by broad industry groupings that approximates the distribution of these groupings in the common stock population of the NYSE, which S&P uses as an assumed model for the composition of the total market.

Relevant criteria employed by S&P include the viability of the particular company, the extent to which that company represents the industry group to which it is assigned, the extent to which the market price of that company’s common stock is generally responsive to changes in the affairs of the respective industry and the market value and trading activity of the common stock of that company.  Ten main groups of companies comprise the reference asset with the number of companies included in each group, as of September 30, 2009, indicated in parentheses: Industrials (56), Utilities (35), Telecommunication Services (9), Materials (30), Information Technology (76), Energy (40), Consumer Staples (41), Consumer Discretionary (80), Health Care (54) and Financials (79).  Changes in the reference asset are reported daily in the financial pages of many major newspapers, on Bloomberg Professional® service under the symbol “SPX” and on the S&P website.  Information contained in the S&P website is not incorporated by reference in, and should not be considered a part of, this pricing supplement.  The reference asset does not reflect the payment of dividends on the stocks included in the reference asset.

Computation of the Reference Asset

S&P currently computes the reference asset as of a particular time as follows:

(i) the product of the market price per share and the number of then outstanding shares of each component stock as determined as of that time (referred to as the “market value” of that stock);

(ii) the market values of all component stocks as of that time are aggregated;

(iii) the average of the market values as of each week in the base period of the years 1941 through 1943 of the common stock of each company in a group of 500 substantially similar companies is determined;

(iv) the mean average market values of all these common stocks over the base period are aggregated (the aggregate amount being referred to as the “base value”);

(v) the current aggregate market value of all component stocks is divided by the base value; and

(vi) the resulting quotient, expressed in decimals, is multiplied by ten.

While S&P currently employs the above methodology to calculate the reference asset, no assurance can be given that S&P will not modify or change this methodology in a manner that may affect the performance of the reference asset.

S&P adjusts the foregoing formula to offset the effects of changes in the market value of a component stock that are determined by S&P to be arbitrary or not due to true market fluctuations.

These changes may result from causes such as:

· the issuance of stock dividends,

· the granting to shareholders of rights to purchase additional shares of stock,

· the purchase of shares by employees pursuant to employee benefit plans,

· consolidations and acquisitions,

· the granting to shareholders of rights to purchase other securities of the company,

· the substitution by S&P of particular component stocks in the reference asset, and

· other reasons.

In these cases, S&P first recalculates the aggregate market value of all component stocks, after taking account of the new market price per share of the particular component stock or the new number of outstanding shares of that stock or both, as the case may be, and then determines the new base value in accordance with the following formula:

Old Base Value  ×  New Market Value  = New Base Value

Old Market Value

The result is that the base value is adjusted in proportion to any change in the aggregate market value of all component stocks resulting from the causes referred to above to the extent necessary to negate the effects of these causes upon the reference asset.

In addition, S&P standard practice is to remove all closely held shares and shares held between corporations who are both in the calculations of the reference asset and a reference asset component’s market value.
