GENERAL

This pricing supplement relates to a single Note offering linked to the Reference Asset identified on the cover page.  The purchaser of a Note will acquire a senior unsecured debt security of HSBC USA Inc. linked to the Reference Asset.  Although the offering of Notes relates to the Reference Asset identified on the cover page, you should not construe that fact as a recommendation as to the merits of acquiring an investment linked to the Reference Asset or any component security included in the Reference Asset or as to the suitability of an investment in the Notes.

You should read this document together with the prospectus dated April 2, 2009, the prospectus supplement dated April 9, 2009, underlying supplement no. 3 dated October 22, 2010 and underlying supplement no. 4 dated October 22, 2010.  If the terms of the Notes offered hereby are inconsistent with those described in the accompanying prospectus supplement, prospectus, or underlying supplements, the terms described in this pricing supplement shall control.  You should carefully consider, among other things, the matters set forth in “Risk Factors” beginning on page PS-6 of this pricing supplement, page S-3 of the prospectus supplement, page US3-1 of underlying supplement no. 3 and page US4-2 of underlying supplement no. 4, as the Notes involve risks not associated with conventional debt securities. We urge you to consult your investment, legal, tax, accounting and other advisors before you invest in the Notes.  As used herein, references to the “Issuer”, “HSBC”, “we”, “us” and “our” are to HSBC USA Inc.

HSBC has filed a registration statement (including a prospectus, a prospectus supplement and each underlying supplement) with the SEC for the offering to which this pricing supplement relates.  Before you invest, you should read the prospectus, prospectus supplement and each underlying supplement in that registration statement and other documents HSBC has filed with the SEC for more complete information about HSBC and this offering.  You may get these documents for free by visiting EDGAR on the SEC’s web site at www.sec.gov.  Alternatively, HSBC Securities (USA) Inc. or any dealer participating in this offering will arrange to send you the prospectus, prospectus supplement and each underlying supplement if you request them by calling toll-free 1-866-811-8049.

PAYMENT ON THE NOTES

Unless we have exercised our Early Redemption Right, on the Maturity Date and for each $1,000 Principal Amount of Notes, you will receive a cash payment equal to the Final Settlement Value (plus any coupon payment) determined as follows:

} If a Trigger Event with respect to the Reference Asset does not occur, 100% of the Principal Amount.

} If a Trigger Event with respect to the Reference Asset occurs and the Final Return of the Least Performing Underlying is positive, an amount equal to 100% of the Principal Amount.

} If a Trigger Event with respect to the Reference Asset occurs and the Final Return of the Least Performing Underlying is negative or zero, an amount equal to 100% of the Principal Amount multiplied by the sum of one plus the Final Return of the Least Performing Underlying, which will result in a Final Settlement Value less than the Principal Amount.

Coupon

On each Coupon Payment Date, for each $1,000 Principal Amount of Notes, you will be paid an amount equal to the product of (a) $1,000 multiplied by (b) the Annual Coupon Rate divided by four.  The expected Coupon Payment Dates are May 25, 2011; August 25, 2011; November 25, 2011; and the Maturity Date.  If any Coupon Payment Date falls on a day that is not a business day (including a Coupon Payment Date that is also the Maturity Date or the Early Redemption Date, as defined below), such Coupon Payment Date will be postponed to the immediately succeeding business day.  If the final Coupon Payment Date (which is also the Maturity Date) is postponed as described under “Final Valuation Date and Maturity Date” below, such final Coupon Payment Date will be postponed until the postponed Maturity Date.  In no event, however, will any additional interest accrue on the Notes as a result of any the foregoing postponements.  For information regarding the record dates applicable to the Coupons paid on the Notes, please see the section entitled “Recipients of Interest Payments” on page S-18 in the accompanying prospectus supplement.

The “Annual Coupon Rate” is 10.50% per annum.

PS-4

Early Redemption Right

The Notes are redeemable at our option in whole, but not in part, on any Coupon Payment Date upon giving notice three business days prior to such Coupon Payment Date. The “Early Redemption Date” is the Coupon Payment Date, if any, for which we have given notice.  If the Notes are redeemed prior to the Maturity Date, you will be entitled to receive only the Principal Amount of the Notes and any coupon payment in respect of Coupon Payment Dates ended on or before the Early Redemption Date. In this case, you will lose the opportunity to continue to be paid Coupons on Coupon Payment Dates that occur after the Early Redemption Date.

Official Closing Value

With respect to the each Underlying, the Official Closing Value on any scheduled trading day will be determined by the calculation agent based upon the closing price of such index fund or closing level of such index, as applicable, displayed on the following pages on Bloomberg Professional® service: for the RTY, page “RTY <INDEX>,” and for the GDX, page “GDX UP <EQUITY>,” and with respect to the GDX, adjusted by the calculation agent as described under “Additional Terms of the Notes—Antidilution and Reorganization Adjustments” in the accompanying underlying supplement no. 4.  With respect to any of the foregoing, if the value for the relevant Underlying is not so displayed on such page, the calculation agent may refer to the display on any successor page on Bloomberg Professional® service or any successor service, as applicable.

Calculation Agent

We or one of our affiliates will act as calculation agent with respect to the Notes.

Trustee

Notwithstanding anything contained in the accompanying prospectus 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.

Paying Agent

Notwithstanding anything contained in the accompanying prospectus supplement to the contrary, 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.

Reference Issuer and Reference Sponsor

With respect to the RTY, the reference sponsor is Russell Investment Group.  With respect to the GDX, the reference issuer is Market VectorsTM ETF Trust.

PS-5

INVESTOR SUITABILITY

The Notes may be suitable for you if:

} You believe that the Official Closing Value of one or both of the Underlyings will not decline by more than the Trigger Value during the Observation Period.

} You are willing to make an investment that is potentially exposed to downside performance of the Least Performing Underlying on a 1-to-1 basis.

} You are unwilling to be exposed to the possibility of early redemption.

} You prefer to receive the distributions paid on the index fund or on stocks comprising the index included in the Reference Asset.

} You prefer a product that provides upside participation in the Reference Asset, as opposed to the coupon being offered with respect to your Notes.

} You are unable or unwilling to hold the Notes to maturity.

} You seek an investment for which there will be an active secondary market.

} You prefer the lower risk, and therefore accept the potentially lower returns, of conventional debt securities with comparable maturities issued by HSBC or another issuer with a similar credit rating.

} You are not willing or are unable to assume the credit risk associated with HSBC, as issuer of the Notes.

RISK FACTORS

We urge you to read the section “Risk Factors” on page S-3 in the accompanying prospectus supplement, on page US3-1 of the accompanying underlying supplement no. 3 and on page US4-2 of the accompanying underlying supplement no. 4.  Investing in the Notes is not equivalent to investing directly in any of the stocks comprising any Underlying, securities held by any Underlying or in any Underlyings themselves, as applicable.  You should understand the risks of investing in the Notes and should reach an investment decision only after careful consideration, with your advisors, of the suitability of the Notes in light of your particular financial circumstances and the information set forth in this pricing supplement and the accompanying prospectus, prospectus supplement and underlying supplements.

In addition to the risks discussed below, you should review “Risk Factors” in the accompanying prospectus supplement and underlying supplement including the explanation of risks relating to the Notes described in the following sections:

} “— Risks Relating to All Note Issuances” in the prospectus supplement;

} “— Additional Risks Relating to Notes with an Equity Security or Equity Index as the Reference Asset” in the prospectus supplement;

} “— Additional Risks Relating to Certain Notes with More than One Instrument Comprising the Reference Asset” in the prospectus supplement;

} “— Additional Risks Relating to Notes with a Reference Asset That is a Commodity or a Contract or Index Relating thereto” in the prospectus supplement;

} “— There are Risks Associated With Small-Capitalization Stocks” in underlying supplement no. 3;

} “—Risks Associated With the Gold Mining Industry” in underlying supplement no. 4;

} “— There are Risks Associated With an Investment in a Concentrated Industry” in underlying supplement no. 4; and

} “— Small-Capitalization or Mid-Capitalization Companies Risk” in underlying supplement no. 4.

You will be subject to significant risks not associated with conventional fixed-rate or floating-rate debt securities.

PS-6

The Notes are not principal protected and you may lose your entire initial investment.

The Notes are not principal protected. The Notes differ from ordinary debt securities in that we will not pay you 100% of the Principal Amount of your Notes if a Trigger Event occurs during the Observation Period and the Final Return of the Least Performing Underlying is negative. In this case, the Payment at Maturity you will be entitled to receive will be less than the Principal Amount of the Notes and you could lose your entire initial investment if the value of the Least Performing Underlying falls to zero. An investment in the Notes is not principal protected and you may receive less at maturity than you originally invested in the Notes, or you may receive nothing at maturity, excluding any coupon payment.

You will not participate in any appreciation in the value of any of the Underlyings included in the Reference Asset.

The Notes will not pay more than the Principal Amount, plus any coupon payment, at maturity or upon early redemption. Even if the Final Return of each Underlying in the Reference Asset is greater than zero (regardless of whether a Trigger Event has occurred), you will not participate in the appreciation of either Underlying. Assuming the Notes are held to maturity, the maximum amount payable with respect to the Notes will not exceed the sum of the Principal Amount plus any coupons.  Under no circumstances, regardless of the extent to which either Underlying appreciates, will your return exceed the total amount of the coupons.  In some cases, you may earn significantly less by investing in the Notes than you would have earned by investing in an instrument directly linked to the performance of the Underlyings.

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, such as the coupons, payment at maturity or upon early redemption, as applicable, 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.

If a Trigger Event occurs with respect to either Underlying, your return will be based on the Final Return of the Least Performing Underlying.

The performance of either of the Underlyings may cause a Trigger Event to occur.  If a Trigger Event does occur, your return will be based on the Final Return of the Least Performing Underlying without regard to the performance of the other Underlying or which Underlying caused the Trigger Event to occur. As a result, you could lose all or some of your initial investment if the Final Return of the Least Performing Underlying is negative, even if there is an increase in the value of the other Underlying.  This could be the case even the other Underlying caused the Trigger Event to occur or the other Underlying increased by an amount greater than the decrease in the Least Performing Underlying.

The Notes are subject to our Early Redemption Right, which limits your ability to accrue interest over the full term of the Notes.

The Notes are subject to our Early Redemption Right and therefore may be redeemed by us on any Coupon Payment Date upon at least three business days notice. If the Notes are redeemed prior to the Maturity Date, you will be entitled to receive only the Principal Amount of your Notes and any coupon payment in respect of Coupon Payment Dates originally scheduled to occur on or before the Early Redemption Date. In such a case, you will lose the opportunity to continue to accrue and be paid coupons in respect of Coupon Payment Dates following the Early Redemption Date. If the Notes are redeemed prior to the Maturity Date, you may be unable to invest in other securities with a similar price of risk that yield as much interest as the Notes.  See “Early Redemption Right” on page PS-5.

Since the Notes are linked to the performance of more than one Underlying, you will be fully exposed to the risk of fluctuations in the values of each Underlying.

Since the Notes are linked to the performance of more than one Underlying, the Notes will be linked to the individual performance of each Underlying. Because the Notes are not linked to a weighted basket, in which the risk is mitigated and diversified among all of the components of a basket, you will be exposed to the risk of fluctuations in the value of the Underlyings to the same degree for each Underlying. For example, in the case of Notes linked to a weighted basket, the return would depend on the weighted aggregate performance of the basket components reflected as the basket return. Thus, the depreciation of any basket component could be mitigated by the appreciation of another basket component, as scaled by the weightings of such basket components. However, in the case of these Notes, the individual performances of each of the Underlyings would not be combined to calculate your return and the depreciation of any Underlying would not be mitigated by the appreciation of the other Underlying. The negative performance of one

PS-7

Underlying could cause a Trigger Event.  As well, if a Trigger Event occurs, your return would depend solely on the Least Performing Underlying.

Changes that affect an Underlying will affect the market value of the Notes and the amount you will receive at maturity.

The policies of the reference sponsor or reference issuer of an Underlying concerning additions, deletions and substitutions of the constituents comprising such Underlying and the manner in which the reference sponsor or reference issuer takes account of certain changes affecting those constituents included in such Underlying may affect the value of such Underlying.  The policies of the reference sponsor or reference issuer with respect to the calculation of the relevant Underlying could also affect the value of such Underlying.  The reference sponsor or reference issuer may discontinue or suspend calculation or dissemination of its relevant Underlying. Any such actions could affect the value of the Notes. 

Please read and pay particular attention to the section “Additional Risks Relating to Notes with an Equity Security or Equity Index as the Reference Asset” in the accompanying prospectus supplement.

An index fund and its underlying index are different.

The performance of an index fund may not exactly replicate the performance of the respective underlying index, because such index fund will reflect transaction costs and fees that are not included in the calculation of the respective underlying index.  It is also possible that an index fund may not fully replicate or may in certain circumstances diverge significantly from the performance of the respective underlying index due to the temporary unavailability of certain securities in the secondary market, the performance of any derivative instruments contained in such fund or due to other circumstances. An index fund may use futures contracts, options, swap agreements, currency forwards and repurchase agreements in seeking performance that corresponds to the respective underlying index and in managing cash flows. Your investment is linked to a Reference Asset which consists of one index fund and therefore any information relating to an underlying index is only relevant to understanding the index that such index fund seeks to replicate.

An index fund is subject to management risk.

The index fund included in the Reference Asset is not managed according to traditional methods of ‘‘active’’ investment management, which involve the buying and selling of securities based on economic, financial and market analysis and investment judgment. Instead, the index fund, utilizing a ‘‘passive’’ or indexing investment approach, attempts to approximate the investment performance of its underlying index by investing in a portfolio of securities that generally replicate the underlying index. Therefore, unless a specific security is removed from the underlying index, the index fund generally would not sell a security because the security’s issuer was in financial trouble. In addition, the index fund is subject to the risk that the investment strategy of the index fund’s investment advisors may not produce the intended results.

There is limited anti-dilution protection.

For certain events affecting shares of the index fund included in the Reference Asset, such as stock splits or extraordinary dividends, the calculation agent may make adjustments to the relevant Closing Value which may affect your Final Settlement Value. However, the calculation agent is not required to make an adjustment for every corporate action which affects the shares of the index fund. If an event occurs that does not require the calculation agent to adjust the amount of the shares of the index fund, the market price of the Notes and the Final Settlement Value may be materially and adversely affected.

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 on the Notes.

Certain built-in costs are likely to adversely affect the value of the Notes prior to maturity.

The original issue price of the Notes includes the placement agent’s commission and the estimated cost of HSBC hedging its obligations under the Notes. 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 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.

PS-8

The Notes lack liquidity.

The Notes will not be listed on any securities exchange. HSBC Securities (USA) Inc. is not required to offer to purchase the Notes in the secondary market, if any exists. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the Notes easily. 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.

Potential conflicts of interest may exist.

HSBC and its affiliates play a variety of roles in connection with the issuance of the Notes, including acting as calculation agent and hedging our obligations under the Notes.  In performing these duties, the economic interests of the calculation agent and other affiliates of ours are potentially adverse to your interests as an investor in the Notes. We will not have any obligation to consider your interests as a holder of the Notes in taking any action that might affect the value of your Notes.

Uncertain tax treatment.

For a discussion of certain of the U.S. federal income tax consequences of your investment in a Note, please see the discussion under “Certain U.S. Federal Income Tax Considerations” herein and the discussion under “Certain U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement.

PS-9

ILLUSTRATIVE EXAMPLES

The following table and examples are provided for illustrative purposes only and are hypothetical. They do not purport to be representative of every possible scenario concerning increases or decreases in the value of any Underlying relative to its Initial Value.  We cannot predict the Official Closing Value of either Underlying at any time during the Observation Period.  The assumptions we have made in connection with the illustrations set forth below may not reflect actual events.  You should not take this illustration or these examples as an indication or assurance of the expected performance of the Reference Asset to which your Notes are linked or return on the Notes.  With respect to the Notes, the Final Settlement Value may be less than the amount that you would have received from a conventional debt security with the same stated maturity, including those issued by HSBC. The numbers appearing in the table below and following examples have been rounded for ease of analysis.

The table below illustrates the total payment on the Notes on a $1,000 investment in the Notes for a hypothetical range of performance for the Least Performing Underlying’s Final Return from -100% to +100%. The following results are based solely on the terms outlined below.  You should consider carefully whether the Notes are suitable to your investment goals.

} Principal Amount: $1,000

} Trigger Value: 62% of the Initial Value of each Underlying.

} Annual Coupon Rate (paid quarterly): 10.50% per annum.

} The Notes are held until maturity and are not redeemed by the Issuer early.

1 The Official Closing Value of each Underlying never falls below its Trigger Value on any trading day during the Observation Period.

2 The Official Closing Value of an Underlying falls below its Trigger Value on a trading day during the Observation Period.

3 Assuming the Notes have been held to maturity, the total amount of the coupons paid on the Notes as of the Maturity Date will equal $105.00, with coupon payments of $26.25 made on each Coupon Payment Date.

PS-10

Hypothetical Examples of the Final Settlement Value

The five examples below set forth a sampling of hypothetical Final Settlement Values for the Notes based on the following:

} Principal Amount of Notes: $1,000

} Trigger Value: 62% of the Initial Value of each Underlying.

} Annual Coupon Rate (paid quarterly): 10.50% per annum.

} Initial Value: 812.96 for the RTY and $58.43 for the GDX.

In addition to the Final Settlement Value, you will be entitled to receive coupon payments quarterly on each Coupon Payment Date, up to and including the Maturity Date (or the Early Redemption Date, as applicable).

The examples provided herein are for illustration purposes only. The actual amount payable on the Notes will depend on if the Notes are called and whether a Trigger Event occurs and, if so, the Final Return of the Least Performing Underlying. You should not take these examples as an indication of potential payments. It is not possible to predict whether a Trigger Event will occur and, if so, whether the Final Return of the Least Performing Underlying will be less than zero, or to what extent the Final Return will be less than zero.

Example 1: We do not exercise our Early Redemption Right and a Trigger Event occurs. Additionally, the Final Return of the Least Performing Underlying is zero or negative.

Underlying	Initial Value	Lowest Official Closing Value of the Underlying during the Observation Period	Final Value on Final Valuation Date
RTY	812.96	325.18 (40% of Initial Value)	569.07 (70% of Initial Value)
GDX	$58.43	$46.74 (80% of Initial Value)	$46.74 (80% of Initial Value)

Since the Official Closing Value of the RTY is below its Trigger Value during the Observation Period, a Trigger Event occurs. The RTY is also the Least Performing Underlying.

The Final Return of the Least Performing Underlying =

    Final Value of the RTY – Initial Value of the RTY

Initial Value of the RTY

= (569.07–  812.96) / 812.96= -30.00%

Final Settlement Value = Principal Amount of the Notes × (1 + Final Return of the Least Performing Underlying)

= $1,000 × (1 + -30.00%) = $700.00

Therefore, with the total coupon payment of $105.00 over the term of the Notes, the total payment on the Notes is $805.00.

Example 2: We do not exercise our Early Redemption Right and a Trigger Event occurs. Additionally, the Final Return of the Least Performing Underlying is less than zero.

Underlying	Initial Value	Lowest Official Closing Value of the Underlying during the Observation Period	Final Value on Final Valuation Date
RTY	812.96	406.48 (50% of Initial Value)	894.26 (110% of Initial Value)
GDX	$58.43	$58.43 (100% of Initial Value)	$43.82 (75% of Initial Value)

Since the Official Closing Value of the RTY is below its Trigger Value during the Observation Period, a Trigger Event occurs. The GDX is the Least Performing Underlying, even though its Official Closing Value never reaches or falls below its hypothetical Trigger Value.

Therefore, the Final Return of the Least Performing Underlying =

PS-11

    Final Value of the GDX – Initial Value of the GDX

Initial Value of the GDX

= ($43.82 – $58.43) / $58.43 = -25.00%

Final Settlement Value  = Principal Amount of the notes × (1 + Final Return of the Least Performing Underlying)

= $1,000 × (1 + -25.00%) = $750.00

Therefore, with the total coupon payment of $105.00 over the term of the Notes, the total payment on the Notes is $855.00.

Example 3: We do not exercise our Early Redemption Right and a Trigger Event occurs. Additionally the Final Return of the Least Performing Underlying is greater than zero.

Underlying	Initial Value	Lowest Official Closing Value of the Underlying during the Observation Period	Final Value on Final Valuation Date
RTY	812.96	325.18 (40% of Initial Value)	894.26 (110% of Initial Value)
GDX	$58.43	$46.74 (80% of Initial Value)	$70.12 (120% of Initial Value)

Since the Official Closing Value of the RTY is below its Trigger Value during the Observation Period, a Trigger Event occurs. The RTY is also the Least Performing Underlying.

The Final Return of the Least Performing Underlying =

    Final Value of the RTY - Initial Value of the RTY

Initial Value of the RTY

= (894.26 – 812.96) / 812.96 = 10.00%

Therefore, since a Trigger Event has occurred and the Final Value of the Least Performing Underlying is positive, the Final Settlement Value equals $1,000.

Additionally, with the total coupon payment of $105.00 over the term of the Notes, the total payment on the Notes is $1,105.00.

Example 4: We do not exercise our Early Redemption Right and a Trigger Event does not occur.

Underlying	Initial Value	Lowest Official Closing Value of the Underlying during the Observation Period	Final Value on Final Valuation Date
RTY	812.96	650.37 (80% of Initial Value)	731.66 (90% of Initial Value)
GDX	$58.43	$52.59 (90% of Initial Value)	$52.59 (90% of Initial Value)

Since the Official Closing Value of each Underlying was not below its Trigger Value, a Trigger Event does not occur.

Therefore, the Final Settlement Value equals $1,000.

Additionally, with the total coupon payment of $105.00 over the term of the Notes, the total payment on the Notes is $1,105.00.

Example 5: We exercise our Early Redemption Right and the Early Redemption Date is August 25, 2011.

Since we exercised our Early Redemption Right, there is an early redemption and you are no longer entitled to receive any Final Settlement Value.  Therefore, on the Early Redemption Date you would receive your $1,000 Principal Amount of Notes plus the coupon payment of $26.25 owed to you on such date.  As a result, on the Early Redemption Date, you would be entitled to receive a total payment of $1,026.25.  Once we exercise our Early Redemption Right, the Underlyings have no relevance in determining the payment owed to you on the Early Redemption Date.

Therefore, with the previous coupon payment of $26.25 paid on May 25, 2011, the total payment on the Notes is $1,052.50.

FINAL VALUATION DATE AND MATURITY DATE

If the Final Valuation Date is not a scheduled trading day for any Underlying, then the Final Valuation Date for such Underlying will be the next succeeding day that is a scheduled trading day (as defined in the relevant underlying supplement with respect to each Underlying) for such Underlying. For each Underlying, the calculation agent will determine whether a market disruption event (as defined in the relevant underlying supplement with respect to each Underlying) exists on the Final Valuation Date with respect to such Underlying independent from the other Underlying; therefore a market disruption event may exist for one Underlying and not exist for the other Underlying. If a market disruption event exists for an Underlying on the Final Valuation Date, then the Final Valuation Date for such Underlying will be the next scheduled trading day for which there is no market disruption event for such Underlying. If such market disruption event continues for five consecutive scheduled trading days, then that fifth scheduled trading day will nonetheless be the Final Valuation Date for such Underlying, and the Official Closing Value with respect to such Underlying will be determined (1) with respect to the Underlying that is an index, by means of the formula for and method of calculating such index which applied just prior to the market disruption event, using the relevant exchange’s traded or quoted price of each stock or other security in such index (or if an event giving rise to a market disruption event has occurred with respect to a stock or other security in such index and is continuing on that fifth scheduled trading day, the calculation agent’s good faith estimate of the value for that stock or other security), or (2) with respect to the Underlying that is an index fund, by the calculation agent, in its sole discretion, using its estimate of the exchange traded prices for such index fund that would have prevailed but for that market disruption event. For the avoidance of doubt, if no market disruption event exists with respect to an Underlying on the originally scheduled Final Valuation Date, the determination of such Underlying’s Official Closing Value will be made on the originally scheduled Final Valuation Date, irrespective of the existence of a market disruption event with respect to the other Underlying. If the Final Valuation Date for either Underlying included in the Reference Asset is postponed, then the Maturity Date will also be postponed to the third business day following the latest of such postponed Final Valuation Dates.

EVENTS OF DEFAULT AND ACCELERATION

If the Notes have become immediately due and payable following an Event of Default (as defined in the accompanying prospectus) with respect to the Notes, the calculation agent will determine (i) the accelerated Payment at Maturity due and payable in the same general manner as described in “Payment at Maturity” in this pricing supplement and (ii) any accrued but unpaid interest payable based upon the Annual Coupon Rate calculated on the basis of a 360-day year consisting of twelve 30-day months.  In such a case, the third scheduled trading day for all of the Underlyings immediately preceding the date of acceleration will be used as the Final Valuation Date for purposes of determining the accelerated Final Return for each Underlying and the Annual Coupon Rate.  If a market disruption event exists with respect to an Underlying on that scheduled trading day, then the accelerated Final Valuation Date for the Reference Asset will be postponed for up to five scheduled trading days (in the same general manner used for postponing the originally scheduled Final Valuation Date).  The accelerated Maturity Date for the Reference Asset will be the fifth business day following such accelerated postponed Final Valuation Date.

If the Notes have become immediately due and payable following an Event of Default, you will not be entitled to any additional payments with respect to the Notes.  For more information, see “Description of Debt Securities — Events of Default” in the accompanying prospectus.

CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS

You should carefully consider, among other things, the matters set forth under the heading “Certain U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement.  Notwithstanding any disclosure in the accompanying prospectus supplement to the contrary, our special U.S. tax counsel in this transaction is Sidley Austin llp.  In the opinion of Sidley Austin llp, special U.S. tax counsel to us, the following discussion summarizes certain of the material U.S. federal income tax consequences of the purchase, beneficial ownership, and disposition of each of the Notes.

There are no statutory provisions, regulations, published rulings or judicial decisions addressing the characterization for U.S. federal income tax purposes of securities with terms that are substantially the same as those of the Notes.  Under one reasonable approach, each Note should be treated as a put option written by you (the “Put Option”) that permits us to “cash settle” the Put Option, and a deposit with us of cash in an amount equal to the Principal Amount of the Note (the “Deposit”) to secure your potential obligation under the Put Option, as described in the prospectus supplement under the heading “Certain U.S. Federal Income Tax Considerations – Certain Equity-Linked Notes – Certain Notes Treated as a Put Option and a Deposit.”  We intend to treat the Notes consistent with this approach and the balance of this summary so assumes.  However, other reasonable approaches are possible.  Pursuant to the terms of the Notes, you agree to treat each Note as consisting of the Deposit and the Put Option for all U.S. federal income tax purposes.  We intend to treat the Deposits as non-contingent debt instruments for U.S. federal income tax purposes.  Please see the discussion under the heading “Certain U.S. Federal Income Tax Considerations—U.S. Federal Income Tax Treatment of the Notes as Indebtedness for U.S. Federal Income Tax Purposes—Payments of Interest” in the accompanying prospectus supplement for certain U.S. federal income tax considerations applicable to non-contingent debt instruments. 

As described in the prospectus supplement under “Certain U.S. Federal Income Tax Considerations – Certain Equity-Linked Notes – Certain Notes Treated as a Put Option and a Deposit,” for purposes of dividing the 10.50 percent Annual Coupon Rate on the Notes among interest on the Deposit and Put Premium, 0.50 percent constitutes interest on the Deposit and 10.00 percent constitutes Put Premium.

If the Notes are redeemed prior to maturity, you should recognize the total Put Premium received as short-term capital gain at that time.

Because there are no statutory provisions, regulations, published rulings or judicial decisions addressing the characterization for U.S. federal income tax purposes of securities with terms that are substantially the same as those of the Notes, other characterizations and treatments are possible and the timing and character of income in respect of the Notes might differ from the treatment described above. We do not plan to request a ruling from the IRS regarding the tax treatment of the Notes, and the IRS or a court may not agree with the tax treatment described in this pricing supplement.  We will not attempt to ascertain whether the issuer of any stock owned by, or included in, one or more of the Underlyings of the Reference Asset would be treated as a passive foreign investment company (“PFIC”) or United States real property holding corporation (“USRPHC”), both as defined for U.S. federal income tax purpose.  In the event that the issuer of any stock owned by, or included in, one or more of the Underlyings of the Reference Asset were treated as a PFIC or USRPHC, certain adverse U.S. federal income tax consequences might apply. You should refer to information filed with the SEC and other authorities by the issuers of stock owned by, or included in, the Underlyings of the Reference Asset, as the case may be, and consult your tax advisor regarding the possible consequences to you in the event that one or more issuers of stock owned by, or included in, one or more of the Underlyings of the Reference Asset is or becomes a PFIC or USRPHC.

PROSPECTIVE PURCHASERS OF NOTES SHOULD CONSULT THEIR TAX ADVISORS AS TO THE FEDERAL, STATE, LOCAL, AND OTHER TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF NOTES.
