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 has 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 up to the Maximum Cap on the Notes of 18.75%, or a maximum Payment at Maturity of $1,187.50 for every $1,000 Principal Amount of Notes. If a Knock-Out Event has not occurred, in addition to the Principal Amount, you will receive at maturity the Contingent Return of 18.75% on the Notes, or a Payment at Maturity of $1,187.50 for every $1,000 Principal Amount of Notes. 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, subject to the Maximum Cap. Because the Notes are our senior unsecured debt obligations, payment of any amount at maturity is subject to our ability to pay our obligations as they become due.

· THE CONTINGENT RETURN APPLIES ONLY IF A KNOCK-OUT EVENT HAS NOT OCCURRED — If a Knock-Out Event has not occurred, you will receive the Principal Amount and the Contingent Return at maturity, even if the Final Level is below the Initial Level.  If a Knock-Out Event has occurred and the Final Level is less than the

-2-

Initial Level, you will lose 1.00% of your Principal Amount for every 1.00% that the Final Level is less than the Initial Level. If a Knock-Out Event has occurred and the Reference Return is -100.00%, you will lose your entire investment.

· DIVERSIFICATION OF THE RUSSELL 2000® INDEX — The return on the Notes is linked to the Russell 2000® Index. The Russell 2000® Index consists of the smallest 2,000 companies included in the Russell 3000® Index and is designed to track the performance of the small capitalization segment of the United States equity market. 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 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 — You should only reach a decision to invest in the Notes after carefully considering, with your advisors, the suitability of the Notes in light of your 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 subject to the Maximum Cap 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 is ever below the Initial Level by a percentage that is more than the Knock-Out Buffer Amount of 40.00% 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.

· YOUR MAXIMUM GAIN ON THE NOTES IS LIMITED TO THE MAXIMUM CAP — If the Final Level is greater than the Initial Level, for each $1,000 Principal Amount of Notes you hold, you will receive at maturity $1,000 plus an additional amount that will not exceed the Maximum Cap of 18.75% of the Principal Amount, regardless of the appreciation in the Reference Asset, which may be significantly greater than the Maximum Cap. Even if a Knock-Out Event does not occur, you will receive an amount equal to $1,000 plus the product of $1,000 multiplied by the Contingent Return which is equal to the Maximum Cap.  YOU WILL NOT RECEIVE A RETURN ON THE NOTES GREATER THAN THE MAXIMUM CAP.

· THE NOTES ARE SUBJECT TO THE 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. As further described in the accompanying prospectus supplement and prospectus, the Notes will rank on par with all of the other unsecured and unsubordinated debt obligations of HSBC, except such obligations as may be preferred by operation of law.  Any payment to be made on the Notes, including any return of principal 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 ABILITY TO RECEIVE THE CONTINGENT RETURN MAY TERMINATE AT ANY TIME DURING THE TERM OF THE NOTES — If the Official Closing Level is ever below the Initial Level by a percentage that is more than the

-3-

Knock-Out Buffer Amount of 40.00% during the Observation Period, you will be fully exposed to any decline in the Reference Asset and will not be entitled to receive the Contingent Return on the Notes. 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 40.00%, 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.

· THERE ARE RISKS ASSOCIATED WITH SMALL CAPITALIZATION STOCKS —The stocks that constitute the Russell 2000® Index are issued by companies with relatively small market capitalization.  The stock prices of smaller companies may be more volatile than stock prices of large capitalization companies.  Small capitalization companies may be less able to withstand adverse economic, market, trade and competitive conditions relative to larger companies.  These companies tend to be less well-established than large market capitalization companies.  Small capitalization companies are less likely to pay dividends on their stocks, and the presence of a dividend payment could be a factor that limits downward stock price pressure under adverse market conditions.

· 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 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.

· THE NOTES LACK LIQUIDITY — The Notes will not be listed on any securities exchange. HSBC Securities (USA) Inc. may 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.

· 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;

-4-

· a variety of economic, financial, political, regulatory or judicial events that affect the Reference Asset or the stock markets generally; 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 illustrates 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 of Notes to $1,000. The hypothetical total returns set forth below reflect the Knock-Out Buffer Amount of 40.00%, the Contingent Return on the Notes of 18.75% and the Maximum Cap of 18.75% and assume an Initial Level of 600.  The actual Initial Level will be determined on the Pricing Date. 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.

(1) The Official Closing Level has not declined, as compared to the Initial Level, by a percentage that is more than 40.00% at any time during the Observation Period.

(2) The Official Closing Level has declined, as compared to the Initial Level, by a percentage that is more than 40.00% 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 600.00 to a Final Level of 606.00. Because a Knock-Out Event has not occurred,  the investor benefits from the Contingent Return and receives a Payment at Maturity of $1,187.50 per $1,000 Principal Amount of Notes.

Example 2: A Knock-Out Event has not occurred, and the level of the Reference Asset decreases from the Initial Level of 600.00 to a Final Level of 510.00. Because a Knock-Out Event has not occurred, the investor benefits from the Contingent Return and receives a Payment at Maturity of $1,187.50 per $1,000 Principal Amount of Notes.

Example 3: A Knock-Out Event has not occurred, and the level of the Reference Asset increases from the Initial Level of 600.00 to a Final Level of 840.00.  Because a Knock-Out Event has not occurred, the investor receives the Contingent Return and receives a Payment at Maturity of $1,187.50 per $1,000 Principal Amount of Notes

-6-

Example 4: A Knock-Out Event has occurred, and the level of the Reference Asset increases from the Initial Level of 600.00 to a Final Level of 840.00.  Because a Knock-Out Event has occurred, and the Reference Return of 40.00% is positive and is greater than the Maximum Cap of 18.75%, the investor receives a Payment at Maturity of $1,187.50 per $1,000 Principal Amount of Notes, the maximum payment of the Notes, calculated as follows:

$1,000 + ($1,000 × 18.75%) = $1,187.50

Example 5: A Knock-Out Event has occurred, and the level of the Reference Asset decreases from the Initial Level of 600.00 to a Final Level of 540.00. 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 Principal Amount of Notes, calculated as follows:

$1,000 + ($1,000 × -10.00%) = $900.00

Example 6: A Knock-Out Event has occurred, and the level of the Reference Asset decreases from the Initial Level of 600.00 to a Final Level of 300.00. Because a Knock-Out Event has occurred and the Reference Return is ­50.00%, the investor is exposed to the negative performance of the Reference Asset and receives a Payment at Maturity of $500.00 per $1,000 Principal Amount of Notes, calculated as follows:

$1,000 + ($1,000 × ­-50.00%) = $500.00

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 the Reference Asset or any of the securities comprising the Reference Asset.  All disclosures contained in this free writing prospectus regarding the 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 the Reference Asset or any constituent included in the 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 Russell 2000® Index

We have derived all information relating to the RTY, 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, Russell Investment Group.  Russell Investment Group is under no obligation to continue to publish, and may discontinue or suspend the publication of the RTY at any time.

Russell Investment Group publishes the RTY

The Russell 2000® Index (“RTY”) is an index calculated, published, and disseminated by the Russell Investment Group, and measures the composite price performance of stocks of 2,000 companies determined by Russell to be part of the U.S. equity market.  All 2,000 stocks are traded on a major U.S. exchange, and form a part of the Russell 3000® Index.  The Russell 3000® Index is composed of the 3,000 largest United States companies as determined by market capitalization and represents approximately 98.00% of the United States equity market.

RTY consists of the smallest 2,000 companies included in the Russell 3000® Index.  RTY is designed to track the performance of the small capitalization segment of the United States equity market.

Only stocks belonging to companies domiciled in the U.S. are allowed into RTY.  Preferred and convertible preferred stock, redeemable shares, warrants, participating preferred stock, trust receipts, rights, pink sheets, OTC Bulletin Board companies and closed-end mutual funds are excluded from RTY.  Real Estate Investment Trusts and Beneficial Trusts however, are eligible for inclusion.

In general, only one class of securities of a company is allowed in RTY, although exceptions to this general rule have been made where the Russell Investment Group has determined that each class of securities acts independently of the other.  Stocks must trade at or above $1.00 on May 31 of each year to be eligible for inclusion in RTY.  However, if a stock falls below $1.00 intra-year, it will not be removed until the next reconstitution if it is still trading below $1.00.

The primary criterion used to determine the initial list of securities eligible for the Russell 3000® Index is total market capitalization, which is defined as the price of a company's shares times the total number of available shares, as described below.  Based on closing values on May 31 of each year, the Russell Investment Group reconstitutes the composition of the Russell 3000® Index using the then existing market capitalizations of eligible companies.  As of the last Friday in June of each year, the Russell Index is adjusted to reflect the reconstitution of the Russell 3000® Index for that year.  Real-time dissemination of RTY began on January 1, 1987.

RTY is a capitalization-weighted index.  RTY reflects changes in the market value (i.e. capitalization) of the component stocks relevant to their market value on a base date.  RTY is determined by adding the market values of the component stocks, which are gotten by multiplying the price of each stock by the number of available shares, to get the total market capitalization of the 2,000 stocks.  The total market capitalization is then divided by a divisor, which gives the adjusted capitalization of RTY on the base date of December 31, 1986.  The most recently traded price for a security will be used in determining RTY.  If a component security is not open for trading, the most recently traded price for that stock will be used.  The divisor is adjusted to reflect certain events in order to provide consistency for RTY.  The events include changes in the number of common shares outstanding for component stocks, company additions or deletions, corporate restructurings, and other changes.  Available shares are considered to be available for trading.  Exclusion of market value held by other listed companies and large holdings by private investors (10% or more) is based on information recorded in Securities and Exchange Commission filings.

Annual reconstitution is the process by which RTY is completely rebuilt.  Reconstitution is a vital part of the creation of a benchmark which accurately represents a particular market segment.  Companies may get bigger or smaller over time, or change in style characteristics.  Reconstitution ensures that the correct companies are represented in RTY.

 Available shares are assumed to be shares available for trading.  Exclusion of capitalization held by other listed companies and large holdings of private investors (10.00% or more) is based on information recorded in Securities and Exchange Commission filings.  Other sources are used in cases of missing or questionable data.

 The following types of shares considered unavailable for the purposes of capitalization determinations:

ESOP or LESOP shares – shares of corporations that have Employee Stock Ownership Plans (“ESOP”) or Leveraged Employee Stock Ownership Plans (“LESOP”) that comprise 10.00% or more of the shares outstanding are adjusted;

Corporate cross-owned shares – when shares of a company in RTY are held by another company also in RTY, this is considered corporate cross-ownership.  Any percentage held in this class will be adjusted;

Large private and corporate shares – when an individual, a group of individuals acting together, or a corporation not in the index owns 10.00% or more of the shares outstanding.  However, institutional holdings (investment companies, partnerships, insurance companies, mutual funds, banks, or venture capital companies) are not included in this class; and

Unlisted share classes – classes of common stock that are not traded on a United States securities exchange or NASDAQ.

 The following summarizes the types of RTY maintenance adjustments and indicates whether or not an index adjustment is required.

“No Replacement” Rule – Securities that leave RTY for any reason (e.g. mergers, acquisitions, or other similar corporate activity) are not replaced.  Therefore, the number of securities in RTY will fluctuate according to corporate activity.

Rule for Corporate Action-Driven Changes – When a stock is acquired, delisted, or moves to the pink sheets or bulletin boards on the floor of a United States securities exchange, the stock is deleted from RTY at the open of trading on the ex-date using the previous day's closing prices.

When acquisitions or mergers take place within RTY, the stock's capitalization moves to the acquiring stock; as a result, mergers have no effect on the total capitalization of RTY.  Shares are updated for the acquiring stock at the time the transaction is final.  Prior to April 1, 2000, if the acquiring stock was a member of a different index (i.e. the Russell 3000® Index or the Russell 1000® Index), the shares for the acquiring stock were not adjusted until month end.

Deleted Stocks – When deleting stocks from RTY as a result of exchange delisting or reconstitution, the price used is the market price on the day of deletion, including potentially the over-the-counter (“OTC”) Bulletin Board price.  Previously, prices used to reflect delisted stocks were the last traded price on the Primary Exchange.  There may be corporate events, like mergers or acquisitions that result in the lack of a current market price for the deleted security and in such an instance the latest Primary Exchange closing price available will be used.

Additions for Spin-Offs – Spin-off companies are added to the parent company's index and capitalization tier of membership, if the spin-off is large enough.  To be eligible, the spun-off company's total market capitalization must be greater than the market-adjusted total market capitalization of the smallest security in RTY at the latest reconstitution.

Quarterly IPO Additions – Eligible companies that have recently completed an initial public offering (“IPO”) are

added to RTY at the end of each calendar quarter based on total market capitalization ranking within the market-adjusted capitalization breaks established during the most recent reconstitution.  Market adjustments will be made using the returns of the Russell 3000® Index.  Eligible companies will be added to RTY using their industry's average style probability established at the latest constitution.

 In order for a company to be added to RTY in a quarter (outside of reconstitution), the IPO company must meet all Russell U.S. Index eligibility requirements.  Also, the IPO company must meet the following criteria on the final trading day of the month prior to quarter-end : (i) price/trade; (ii) rank larger in total market capitalization than the market-adjusted smallest company in RTY as of the latest June reconstitution; and (iii) meet criteria (i) and (ii) during an initial offering period.

 Each month, RTY is updated for changes to shares outstanding as companies report changes in share capital to the Securities and Exchange Commission.  Only cumulative changes to shares outstanding greater than 5.00% are reflected in RTY.  This does not affect treatment of major corporate events, which are effective on the ex-date.
