Summary

The Market-Linked Step Up Notes Linked to the S&P 500^® Index due April 24, 2014 (the “notes”) are our senior unsecured debt securities and are not a direct or indirect obligation of any third party. The notes are not deposit liabilities or other obligations of a bank and are not guaranteed or insured by the Federal Deposit Insurance Corporation or any other governmental agency of the United States or any other jurisdiction. The notes will rank equally with all of our other senior unsecured debt. Any payments due on the notes, including any repayment of principal, depends on the credit risk of HSBC and its ability to satisfy its obligations as they come due. The notes provide you with a Step Up Payment if the Ending Value (as determined below) of the S&P 500^® Index (the “Index”) is equal to or greater than the Starting Value, but is not greater than the Step Up Value. If the Ending Value is greater than the Step Up Value, you will participate on a 1-for-1 basis in the increase in the level of the Index above the Starting Value. If the Ending Value is less than the Starting Value, you will lose all or a portion of the principal amount of your notes.

The terms and risks of the notes are contained in this term sheet and the documents listed below (together, the “Note Prospectus”). The documents have been filed as part of a registration statement with the SEC, which may, without cost, be accessed on the SEC website as indicated below or obtained from MLPF&S by calling 1-866-500-5408:

Hypothetical Payments at Maturity

The following table and examples are for purposes of illustration only. They are based on hypothetical values and show hypothetical returns on the notes. The actual amount you receive and the resulting total rate of return will depend on the actual Starting Value and Threshold Value, Ending Value, Step Up Value and the term of your investment.

The following table is based on a Starting Value and Threshold Value of 100, the Step Up Value of 120.54, and the Step Up Payment of $2.054 per unit. It illustrates the effect of a range of Ending Values on the Redemption Amount per unit of the notes and the total rate of return to holders of notes. The following examples do not take into account any tax consequences from investing in the notes.

Ending Value	Percentage Change from the Starting Value to the Ending Value	Redemption Amount per Unit	Total Rate of Return on the Notes

Market-Linked Step Up Notes TS-5

Market-Linked Step Up Notes Linked to the S&P 500^® Index due April 24, 2014  

The Index

We have derived all information relating to the S&P 500^® Index 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 S&P.  S&P is under no obligation to continue to publish, and may discontinue or suspend the publication of the Index at any time.

S&P Publishes the Index

The Index is intended to provide an indication of the pattern of common stock price movement.  The calculation of the level of the Index, discussed below in further detail, is based on the relative value of the aggregate Market Value (as defined below) 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.  S&P chooses companies for inclusion in the Index 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 Standard & Poor’s Stock Guide Database, which S&P uses as an assumed model for the composition of the total market.  S&P may from time to time in its sole discretion, add companies to or delete companies from, the Index to achieve these objectives. 

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 industry groups comprise the Index:  Information Technology, Financials, Consumer Staples, Health Care, Energy, Industrials, Consumer Discretionary, Utilities, Materials and Telecommunication Services.  Changes in the Index 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 document. 

The Index does not reflect the payment of dividends on the stocks included in the Index and therefore the payment on the notes will not produce the same return you would receive if you were able to purchase such underlying stocks and hold them until the maturity date or earlier call.

Computation of the Index 

Prior to March 2005, the Market Value of a component stock was calculated as the product of the market price per share and the total number of outstanding shares of the component stock.  In March 2004, S&P announced that it would transition the Index to float adjusted market capitalization weights.  The transition began in March 2005 and was completed in September 2005.  S&P’s criteria for selecting stock for the Index was not changed by the shift to float adjustment.  However, the adjustment affects each company’s weight in the Index (i.e., its Market Value).  Currently, S&P calculates the Index based on the total float-adjusted market capitalization of each component stock, where each stock’s weight in the Index is proportional to its float-adjusted Market Value.

Under float adjustment, the share counts used in calculating the Index reflect only those shares that are available to investors, not all of a company’s outstanding shares.  S&P defines three groups of shareholders whose holdings are subject to float adjustment:

• holdings by other publicly traded corporations, venture capital firms, private equity firms, strategic partners, or leveraged buyout groups;

• holdings by government entities, including all levels of government in the U.S. or foreign countries; and

• holdings by current or former officers and directors of the company, founders of the company, or family trusts of officers, directors, or founders, as well as holdings of trusts, foundations, pension funds, employee stock ownership plans or other investment vehicles associated with and controlled by the company.

However, treasury stock, stock options, restricted shares, equity participation units, warrants, preferred stock, convertible stock, and rights are not part of the float.  In cases where holdings in a group exceed 10% of the outstanding shares of a company, the holdings of that group are excluded from the float adjusted count of shares to be used in the index calculation.  Mutual funds, investment advisory firms, pension funds, or foundations not associated with the company and investment funds in insurance companies, shares of a U.S. company traded in Canada as “exchangeable shares,” shares that trust beneficiaries may buy or sell without difficulty or significant additional expense beyond typical brokerage fees, and, if a company has multiple classes of stock outstanding, shares in an unlisted or non-traded class if such shares are convertible by shareholders without undue delay and cost, are also part of the float.

For each stock, an investable weight factor (“IWF”) is calculated by dividing the available float shares, defined as the total shares outstanding less shares held in one or more of the three groups listed above where the group holdings exceed 10% of the outstanding shares, by the total shares outstanding.  The float-adjusted index is then calculated by dividing the sum of the IWF multiplied by both

Market-Linked Step Up Notes TS-6

Market-Linked Step Up Notes Linked to the S&P 500^® Index due April 24, 2014  

the price and the total shares outstanding for each stock by an Index divisor (the “Divisor”).  For companies with multiple classes of stock, S&P calculates the weighted average IWF for each stock using the proportion of the total company market capitalization of each share class as weights.

As of the date of this term sheet, the Index is also calculated using a base-weighted aggregate methodology:  the level of the Index reflects the total Market Value of all the component stocks relative to the Index base period of 1941-43.  The daily calculation of the Index is computed by dividing the Market Value of the Index component stocks by a Divisor, which is adjusted from time to time as discussed below.

The simplest capitalization weighted index can be thought of as a portfolio consisting of all available shares of the stocks in the index.  While this might track this portfolio’s value in dollar terms, it would probably yield an unwieldy number in the trillions.  Therefore, the actual number used in the Index is scaled to a more easily handled number, currently in the thousands, by dividing the portfolio Market Value by the Divisor.

Ongoing maintenance of the Index includes monitoring and completing the adjustments for additions and deletions of the constituent companies, share changes, stock splits, stock dividends and stock price adjustments due to company restructurings or spin-offs.  Continuity in the level of the Index is maintained by adjusting the Divisor for all changes in the Index constituents’ share capital after the base period of 1941-43 with the level of the Index as of the base period set at 10.  Some corporate actions, such as stock splits and stock dividends do not require Divisor adjustments because following a stock split or stock dividend, both the stock price and number of shares outstanding are adjusted by S&P so that there is no change in the Market Value of the component stock.  All stock split and dividend adjustments are made after the close of trading on the day before the ex-date.

To prevent the level of the Index from changing due to corporate actions, all corporate actions which affect the total Market Value of the Index also require a Divisor adjustment.  By adjusting the Divisor for the change in total Market Value, the level of the Index remains constant.  This helps maintain the level of the Index as an accurate barometer of stock market performance and ensures that the movement of the Index does not reflect the corporate actions of individual companies in the Index.  All Divisor adjustments are made after the close of trading and after the calculation of the closing levels of the Index.  As noted in the preceding  paragraph, some corporate actions, such as stock splits and stock dividends, require simple changes in the common shares outstanding and the stock prices of the companies in the Index and do not require Divisor adjustments.

The table below summarizes the types of Index maintenance adjustments and indicates whether or not a Divisor adjustment is required.

Type of Corporate Action	Comments	Divisor Adjustment
Company added/deleted	Net change in market value determines Divisor adjustment.	Yes
Change in shares outstanding	Any combination of secondary issuance, share repurchase or buy back—share counts revised to reflect change.	Yes
Stock split	Share count revised to reflect new count.  Divisor adjustment is not required since the share count and price changes are offsetting.	No
Spin-off	If spun-off company is not being added to the index, the divisor adjustment reflects the decline in Index Market Value (i.e., the value of the spun-off unit).	Yes
Spin-off	Spun-off company added to the Index, no company removed from the Index.	No
Spin-off	Spun-off company added to the Index, another company removed to keep number of names fixed.  Divisor adjustment reflects deletion.	Yes

Market-Linked Step Up Notes TS-7

Market-Linked Step Up Notes Linked to the S&P 500^® Index due April 24, 2014  

Change in IWF	Increasing (decreasing) the IWF increases (decreases) the total market value of the index.  The Divisor change reflects the change in market value caused by the change to an IWF.	Yes
Special dividend	When a company pays a special dividend the share price is assumed to drop by the amount of the dividend; the divisor adjustment reflects this drop in Index Market Value.	Yes
Rights offering	Each shareholder receives the right to buy a proportional number of additional shares at a set (often discounted) price.  The calculation assumes that the offering is fully subscribed.  Divisor adjustment reflects increase in market cap measured as the shares issued multiplied by the price paid.	Yes

Each of the corporate events exemplified in the table requiring an adjustment to the Divisor has the effect of altering the Market Value of the component stock and consequently of altering the aggregate Market Value of the Index component stocks (the “Post-Event Aggregate Market Value”).  In order that the level of the Index (the “Pre-Event Index Value”) not be affected by the altered Market Value (whether increase or decrease) of the affected component stock, a new Divisor (“New Divisor”) is derived as follows:

Post-Event Aggregate Market Value	=	Pre-Event Index Value
New Divisor
New Divisor	=	Post-Event Aggregate Market Value
		Pre-Event Index Value

Another large part of the Index maintenance process involves tracking the changes in the number of shares outstanding of each of the companies whose stocks are included in the Index.  Four times a year, on a Friday close to the end of each calendar quarter, the share totals of companies in the Index are updated as required by any changes in the number of shares outstanding and then the Index Divisor is adjusted accordingly.  In addition, changes in a company’s shares outstanding of 5% or more due to mergers, acquisitions, public offerings, private placements, tender offers, Dutch auctions or exchange offers are made as soon as reasonably possible.  Other changes of 5% or more (due to, for example, company stock repurchases, redemptions, exercise of options, warrants, conversion of preferred stock, notes, debt, equity participations or other recapitalizations) are made weekly, and are announced on Wednesdays for implementation after the close of trading on the following Wednesday.  If a 5% or more change causes a company’s IWF to change by 5 percentage points or more (for example from 0.80 to 0.85), the IWF will be updated at the same time as the share change, except IWF changes resulting from partial tender offers will be considered on a case-by-case basis.  Changes to an IWF of less than 5 percentage points are implemented at the next IWF review, which occurs annually.  In the case of certain rights issuances, in which the number of rights issued and/or terms of their exercise are deemed substantial, a price adjustment and share increase may be implemented immediately.

MLPF&S may repurchase and resell the notes, with repurchases and resales being made at prices related to then-prevailing market prices or at negotiated prices. MLPF&S may act as principal or agent in these market-making transactions; however it is not obligated to engage in any such transactions. The distribution of the Note Prospectus in connection with these offers or sales will be solely for the purpose of providing investors with the description of the terms of the notes that was made available to investors in connection with their initial offering. Secondary market investors should not, and will not be authorized to, rely on the Note Prospectus for information regarding HSBC or for any purpose other than that described in the immediately preceding sentence.

Role of MLPF&S

MLPF&S will participate as selling agent in the distribution of the notes. Under our distribution agreement with MLPF&S, MLPF&S will purchase the notes from us as principal at the public offering price indicated on the cover of this term sheet, less the indicated underwriting discount. In connection with hedging our obligations under the notes, we will enter into a hedge transaction with an affiliate of MLPF&S, which will include a charge of up to $0.075 per unit representing an estimated profit credited to MLPF&S through the hedge transaction. The public offering price you pay for the notes includes this charge and the underwriting discount. This charge and fee reduce the economic terms of the notes. In arranging the hedge transaction for the notes, MLPF&S seeks competitive terms from third parties, which could include one of our affiliates. Additional profits and losses may be realized by the hedge providers from these hedging transactions. For further information regarding how these fees and hedging costs may affect the price at which you will be able to sell the notes in secondary market transaction and conflicts of interest, see “Risk Factors―General Risks Relating to the Notes” beginning on page S-8 of product supplement SUN-2 and “Use of Proceeds” on page S-16 of product supplement SUN-2.

Summary Tax Consequences

You should consider the U.S. federal income tax consequences of an investment in the notes, including the following:

§ There is no statutory, judicial, or administrative authority directly addressing the characterization of the notes.

§ You agree with us (in the absence of an administrative determination, or judicial ruling to the contrary) to characterize and treat the notes for all tax purposes as pre-paid forward contracts or executory contracts with respect to the Index.

§ Under this characterization and tax treatment of the notes, a U.S. Holder (as defined in product supplement SUN-2) generally will recognize capital gain or loss upon maturity or upon a sale or exchange of the notes prior to maturity. This capital gain or loss generally will be long-term capital gain or loss if you held the notes for more than one year.

§ No assurance can be given that the IRS or any court will agree with this characterization and tax treatment.

You should consult your own tax advisor concerning the U.S. federal income tax consequences to you of acquiring, owning, and disposing of the notes, as well as any tax consequences arising under the laws of any state, local, foreign, or other tax jurisdiction and the possible effects of changes in U.S. federal or other tax laws. You should carefully review the discussion under the section entitled “U.S. Federal Income Tax Summary" beginning on page S-30 of product supplement SUN-2.

Market-Linked Investments Classification

MLPF&S classifies certain market-linked investments (the “Market-Linked Investments”) into categories, each with different investment characteristics. The following description is meant solely for informational purposes and is not intended to represent any particular Enhanced Return Market-Linked Investment or guarantee any performance.

Enhanced Return Market-Linked Investments are short- to medium-term investments that offer you a way to enhance exposure to a particular market view without taking on a similarly enhanced level of market downside risk. They can be especially effective in a flat to moderately positive market (or, in the case of bearish investments, a flat to moderately negative market). In exchange for the potential to receive better-than market returns on the linked asset, you must generally accept market downside risk and capped upside potential. As these investments are not market downside protected, and do not assure full repayment of principal at maturity, you need to be prepared for the possibility that you may lose all or part of your investment.
