The Notes

The Notes may be suitable for investors who believe the value of the Underlyings will remain flat or appreciate and who seek the potential for enhanced quarterly coupon payments (relative to the yield on traditional conventional debt securities with a similar term and issued by issuers with a credit rating similar to ours), regardless of the performance of the Reference Asset as long as the Notes are not automatically called.

If the Notes are not automatically called and if a Trigger Event does not occur during the Observation Period, you will receive the Principal Amount of your Notes at maturity plus any unpaid coupon payments.

If the Notes are not automatically called and if a Trigger Event occurs with respect to any of the Underlyings in the Reference Asset during the Observation Period, you may lose some or all of your initial investment, but will keep any coupon payments made to you during the term of the Notes. If you lose some or all of your initial investment, even with any coupon payments, your yield on an investment in the Notes may be negative.

If all Underlyings are at or above their respective Initial Levels on any Call Observation Date, your Notes will be automatically called and you will receive a payment equal to 100% of the Principal Amount together with any unpaid coupon payments on the corresponding Call Payment Date.

The offering period for the Notes is through May     , 2013

 

FWP-2

Illustration of Payment Scenarios Your payment on the Notes will depend on whether the Notes have been automatically called and whether a Trigger Event occurs. Regardless of whether a Trigger Event occurs, you will receive your quarterly coupons on each Coupon Payment Date, subject to your Notes being automatically called. If you lose some or all of your initial investment, even with any coupon payments, your yield on an investment in the Notes may be negative.

PAYMENT ON THE NOTES

Call Feature

The Notes will be automatically called if the Official Closing Level of each Underlying is at or above its Initial Level on any Call Observation Date. If the Notes are automatically called, investors will receive, on the corresponding Call Payment Date, a cash payment per $1,000 Principal Amount of Notes equal to 100% of the Principal Amount together with any unpaid coupon payment.

Maturity

Unless the Notes are automatically called, 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 the final coupon payment) determined as follows:

} If a Trigger Event does not occur, 100% of the Principal Amount.

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

} If a Trigger Event occurs and the Final Return of the Least Performing Underlying is negative, 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

Unless the Notes are automatically called, the Coupon is paid quarterly on each Coupon Payment Date at the applicable Coupon Rate. The expected Coupon Payment Dates are set forth above. The Coupon payable will be computed using the actual number of days in the applicable Coupon Payment Period, and on the basis of a 360-day year. The Coupon Payment Dates are subject to postponement as described under “Description of Notes—Floating-Rate Notes—If a Payment Date is Not a Business Day” in the accompanying prospectus supplement. For information regarding the record dates applicable to the Coupons paid on the Notes, please see the section

FWP-7

entitled “Description of Notes―Interest and Principal Payments―Recipients of Interest Payments” on page S-11 in the accompanying prospectus supplement.

The Coupon Rate will be reset quarterly at a floating rate equal to 3-Month USD LIBOR plus a Spread that will be at least 4.50%.

Official Closing Level

With respect to each Underlying, the Official Closing Level on any trading day will be determined by the calculation agent based upon the closing level of such index, displayed on the following pages on the Bloomberg Professional^® service: for SPX, page “SPX <INDEX>”, for SX5E page “SX5E <INDEX>”, and for NKY page “NKY <INDEX>”. With respect to any of the foregoing, if the level for the relevant Underlying is not so displayed on such page, the calculation agent may refer to the display on any successor page on the Bloomberg Professional^® service or any successor service, as applicable.

Observation Period

The period from but excluding the Trade Date to and including the Final Valuation Date, subject to adjustment as described under “Additional Terms of the Notes―Observation Periods” in the accompanying Equity Index Underlying Supplement.

Business Day

A “business day” means any day, other than a Saturday or Sunday, that is neither a legal holiday nor a day on which banking institutions are authorized or required by law or regulation to close in the City of New York.

Payment When Offices or Settlement Systems Are Closed

If any payment is due on the Notes on a day that would otherwise be a “business day” but is a day on which the office of a paying agent or a settlement system is closed, we will make the payment on the next business day when that paying agent or system is open. Any such payment will be deemed to have been made on the original due date, and no additional payment will be made on account of the delay.

Calculation Agent

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

Reference Sponsor

With respect to SPX, S&P Dow Jones Indices LLC, a subsidiary of The McGraw-Hill Companies, Inc., is the reference sponsor. With respect to SX5E, the Deutsche Börse AG and SIX Group AG are the reference sponsors. With respect to NKY, Nikkei Inc. is the reference sponsor.

FWP-8

INVESTOR SUITABILITY

The Notes may be suitable for you if:

} You believe that the Official Closing Level of each of the Underlyings will not be below its Trigger Level on any trading day 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 willing to make an investment that provides quarterly interest payments at a variable rate linked to 3-Month USD LIBOR.

} You are willing to hold Notes that will be automatically called on any Call Observation Date on which the Official Closing Level of each Underlying is at or above its Initial Level.

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

} You are willing to forgo distributions paid on the stocks comprising the indices included in the Reference Asset.

} You are willing to hold the Notes to maturity.

} You are comfortable with the creditworthiness of HSBC, as Issuer of the Notes.

The Notes may not be suitable for you if:

} You believe that the Official Closing Level of one or more of the Underlyings will be below its Trigger Level on any trading day during the Observation Period.

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

FWP-9

RISK FACTORS

We urge you to read the section “Risk Factors” beginning on page S-3 in the accompanying prospectus supplement and beginning on page S-1 of the accompanying Equity Index Underlying Supplement. Investing in the Notes is not equivalent to investing directly in any of the stocks comprising any of the Underlyings. 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 free writing prospectus and the accompanying prospectus, prospectus supplement and Equity Index Underlying Supplement.

In addition to the risks discussed below, you should review “Risk Factors” in the accompanying prospectus supplement and Equity Index 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; and

} “—General risks related to Indices” in the Equity Index Underlying Supplement.

} “—Securities Prices Generally Are Subject to Political, Economic, Financial and Social Factors that Apply to the Markets in which They Trade and, to a Lesser Extent, Foreign Markets” in the Equity Index Underlying Supplement; and

} “—Time Differences Between the Domestic and Foreign Markets and New York City May Create Discrepancies in the Trading Level or Price of the Notes” in the Equity Index Underlying Supplement;

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

The Notes do not guarantee return of principal and you may lose your entire initial investment.

The Notes do not guarantee return of principal. The Notes differ from ordinary debt securities in that we will not pay you 100% of the Principal Amount of your Notes if the Notes are not automatically called and 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 level of the Least Performing Underlying falls to zero. You may receive less at maturity than you originally invested in the Notes, or you may receive nothing at maturity, excluding any coupon payment. Payment of any amount at maturity is subject to the credit risk of HSBC.

The Coupon Rate for Each Quarterly Coupon Payment Period Is Uncertain.

You will receive a quarterly Coupon on the applicable Coupon Payment Date that accrues at a rate per annum equal to 3-Month USD LIBOR plus at least 4.50% per annum. 3-Month USD LIBOR may be influenced by a number of factors, including (but not limited to) monetary policies, fiscal policies, inflation, general economic conditions and public expectations with respect to such factors. The effect that any single factor may have on 3-Month USD LIBOR may be partially offset by other factors. We cannot predict the factors that may cause 3-Month USD LIBOR to increase or decrease.

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

The Notes will not pay more than the Principal Amount, plus any unpaid coupon payment, at maturity or if the Notes are automatically called. 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 any 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 coupon payments. Under no circumstances, regardless of the extent to which the level of any Underlying appreciates, will your return exceed the total amount of the coupon payments. 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 included in the Reference Asset.

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 securities 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 coupons and any return of principal 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.

FWP-10

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

The performance of any of the Underlyings may cause a Trigger Event to occur. If a Trigger Event occurs and the Notes are not automatically called, your return will be based on the Final Return of the Least Performing Underlying without regard to the performance of the other Underlyings 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 and a Trigger Event occurs, even if there is an increase in the level of the other Underlyings. This could be the case even if another 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 may be automatically called prior to the Maturity Date.

If the Notes are automatically called early, the holding period over which you will receive coupon payments could be as little as one year. There is no guarantee that you would be able to reinvest the proceeds from an investment in the Notes at a comparable return for a similar level of risk in the event the Notes are automatically called prior to the Maturity Date.

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 levels 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 prices 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 performance of each of the Underlyings would not be combined to calculate your return and the depreciation of any of the Underlyings would not be mitigated by the appreciation of the other Underlyings. Instead, your return would depend on the Least Performing Underlying of the Underlyings to which the Notes are linked.

Changes that affect the Reference Asset may affect the market value of the Notes and the amount you will receive at maturity.

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

The Notes are not insured or guaranteed 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 or guaranteed 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.

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 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.

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

FWP-11

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.

Risks associated with non-U.S. companies.

The levels of the SX5E and NKY depend upon the stocks of non-U.S. companies, and thus involve risks associated with the home countries of those non-U.S. companies. The prices of these non-U.S. stocks may be affected by political, economic, financial and social factors in the home country of each applicable company, including changes in that country’s government, economic and fiscal policies, currency exchange laws or other laws or restrictions, which could affect the value of the securities. These foreign securities may have less liquidity and could be more volatile than many of the securities traded in U.S. or other securities markets. Direct or indirect government intervention to stabilize the relevant foreign securities markets, as well as cross shareholdings in foreign companies, may affect trading levels or prices and volumes in those markets. The other special risks associated with foreign securities may include, but are not limited to: less liquidity and smaller market capitalizations; less rigorous regulation of securities markets; different accounting and disclosure standards; governmental interference; currency fluctuations; higher inflation; and social, economic and political uncertainties. These factors may adversely affect the performance of the SX5E or NKY and, as a result, the value of your notes.

The securities will not be adjusted for changes in exchange rates.

Although the equity securities held by the SX5E and NKY are traded in currencies other than U.S. dollars, and your securities are denominated in U.S. dollars, the amount payable on your notes at maturity, if any, will not be adjusted for changes in the exchange rates between the U.S. dollar and the currencies in which these non-U.S. equity securities are denominated. Changes in exchange rates, however, may also reflect changes in the applicable non-U.S. economies that in turn may affect the level of the SX5E or NKY, and therefore your notes. The amount we pay in respect of your notes on the maturity date, if any, will be determined solely in accordance with the procedures described in this free writing prospectus.

Uncertain tax treatment.

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

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 3-Monht LIBOR or the level of any Underlying relative to its Initial Level. We cannot predict 3-Month USD LIBOR or the Official Closing Level of any Underlying or at any time during the Observation Period, including on a Call Observation Date, Coupon Determination Date or on the Final Valuation Date. 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 3-Month USD LIBOR, the Reference Asset, or the return on 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 the Least Performing Underlying’s Final Returns from -100% to +100%. The following results are based solely on the assumptions outlined below. You should consider carefully whether the Notes are suitable to your investment goals.

Principal Amount:	$1,000
Trigger Level:	50% of the Initial Level of each Underlying
Hypothetical Coupon Rate:	1.25% per quarter (5.00% per annum). The actual Coupon Rate will reset on each Coupon Determination Date and will equal the applicable 3-Month USD LIBOR plus the Spread.

The Notes are held until maturity and are not automatically called.

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

² The Official Closing Level of any of the Underlyings falls below its Trigger Level on any trading day during the Observation Period.

³ Assuming a hypothetical Coupon Rate of 1.25% on each Coupon Determination Date (5.00% per annum) and that the Notes have been held to maturity, the hypothetical total amount of the coupons paid on the Notes as of the Maturity Date will equal $250, with hypothetical coupon payments of $12.50 made on each Coupon Payment Date.

FWP-13

Hypothetical Examples of the Final Settlement Value

The three examples below set forth a sampling of hypothetical Final Settlement Values based on the following assumptions:

Principal Amount:	$1,000
Trigger Level:	50% of the Initial Level of each Underlying
Hypothetical Coupon Rate:	1.25% per quarter (5.00% per annum). The actual Coupon Rate will reset on each Coupon Determination Date and will equal the applicable 3-Month USD LIBOR plus the Spread.
Hypothetical Initial Levels:	1,500.00 with respect to the SPX, 2,500.00 with respect to the SX5E, and 15,000 with respect to the NKY

The actual Initial Levels with respect to the SPX, the SX5E, and the NKY will be determined on the Pricing Date.

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 Call Payment Date corresponding to a Call Observation Date on which the Notes are automatically called, if applicable).

The examples provided herein are for illustration purposes only. The actual Final Settlement Value, if any, will depend on whether the Notes are automatically called and 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 the Notes will be automatically called and a Trigger Event will occur and, if so, whether and to what extent the Final Return of the Least Performing Underlying will be less than zero.

Example 1: The Notes are not automatically called and a Trigger Event occurs, even though the Least Performing Underlying never reaches or falls below its Trigger Level. Additionally, the Final Return of the Least Performing Underlying is less than zero.

Underlying	Initial Level	Lowest Official Closing Level During the Observation Period	Final Level
SPX	1,500.00	1,275.00 (85.00% of Initial Level)	1,320.00 (88.00% of Initial Level)
5X5E	2,500.00	1,125.00 (45.00% of Initial Level)	2,375.00 (95.00% of Initial Level)
NKY	15,000.00	13,500.00 (90.00% of Initial Level)	14,700.00 (98.00% of Initial Level)

Since the Official Closing Level of SX5E is below its Trigger Level during the Observation Period, a Trigger Event occurs. SPX is the Least Performing Underlying, even though its Official Closing Level never falls below its Trigger Level.

Therefore, the Final Return of the Least Performing Underlying =

    Final Level of SPX – Initial Level of SPX    
Initial Level of SPX

= (1,320.00 – 1,500.00) / 1,500.00= -12.00%

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

= $1,000 × (1 + -12%) = $880.00

Therefore, with hypothetical total coupon payments of $250.00 over the term of the Notes, the total payment on the Notes is $1,130.

FWP-14

Example 2: The Notes are not automatically called and a Trigger Event does not occur.

Underlying	Initial Level	Lowest Official Closing Level During the Observation Period	Final Level
SPX	1,500.00	1,275.00 (85.00% of Initial Level)	1,350.00 (90.00% of Initial Level)
5X5E	2,500.00	2,250.00 (90.00% of Initial Level)	2,325.00 (93.00% of Initial Level)
NKY	15,000.00	13,800.00 (92.00% of Initial Level)	13,050.00 (87.00% of Initial Level)

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

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

Additionally, with hypothetical total coupon payments of $250.00 over the term of the Notes, the total payment on the Notes is $1,250.00.

Example 3: The Notes are automatically called on the first Call Observation Date.

Underlying	Initial Level	Official Closing Level on the first Call Observation Date
SPX	1,500.00	1,600.00
5X5E	2,500.00	2,550.00
NKY	15,000.00	15,250.00

Since the Official Closing Level of all Underlyings was at or above their respective Initial Levels, the Notes were automatically called and you are no longer entitled to receive any Final Settlement Value. Therefore, on the corresponding Call Payment Date you would receive your $1,000 Principal Amount of Notes plus the hypothetical coupon payment of $12.50 owed to you on that date. As a result, on the first Call Payment Date, you would be entitled to receive a total payment of $1,012.50. Once the Notes are automatically called, the Underlyings have no relevance in determining the payment owed to you on the corresponding Call Payment Date.

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 free writing prospectus and (ii) any accrued but unpaid interest payable based upon the Coupon Rate calculated using the actual number of days in the applicable Coupon Payment Period, and on the basis of a 360-day year In that case, the scheduled trading day preceding the date of acceleration will be used as the Final Valuation Date for purposes of determining the accelerated Final Return for each Underlying. If a market disruption event exists with respect to an Underlying on that scheduled trading day, then the accelerated Final Valuation Date 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 will also be postponed by an equal number of business days. For the avoidance of doubt, if no market disruption event exists with respect to an Underlying on the scheduled trading day preceding the date of acceleration, the determination of such Underlying’s Final Return will be made on such date, irrespective of the existence of a market disruption event with respect to the other Underlying occurring on such 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 — Senior Debt Securities — Events of Default” in the accompanying prospectus.

SUPPLEMENTAL PLAN OF DISTRIBUTION (CONFLICTS OF INTEREST)

We have appointed HSBC Securities (USA) Inc., an affiliate of HSBC, as the agent for the sale of the Notes. Pursuant to the terms of a distribution agreement, HSBC Securities (USA) Inc. will purchase the Notes from HSBC at the price to public less the underwriting discount set forth on the cover page of the pricing supplement to which this free writing prospectus relates, for distribution to other registered broker-dealers or will offer the Notes directly to investors. HSBC Securities (USA) Inc. proposes to offer the Notes at the price to public set forth on the cover page of this free writing prospectus. HSBC USA Inc. or one of our affiliates may pay varying underwriting discounts of up to 1.50% per $1,000 Principal Amount of Notes in connection with the distribution of the Notes to other registered broker-dealers.

An affiliate of HSBC has paid or may pay in the future an amount to broker-dealers in connection with the costs of the continuing implementation of systems to support the Notes.

In addition, HSBC Securities (USA) Inc. or another of its affiliates or agents may use the pricing supplement to which this free writing prospectus relates in market-making transactions after the initial sale of the Notes, but is under no obligation to make a market in the Notes and may discontinue any market-making activities at any time without notice.

See “Supplemental Plan of Distribution (Conflicts of Interest)” on page S-49 in the prospectus supplement.

U.S. FEDERAL INCOME TAX CONSIDERATIONS

You should carefully consider, among other things, the matters set forth under the heading “U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement.  In the opinion of Morrison & Foerster LLP, special U.S. tax counsel to us, the following discussion summarizes the 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 “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 “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 U.S. federal income tax considerations applicable to non-contingent debt instruments. 

As described in the prospectus supplement under “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 Coupon Rate of 3-Month USD LIBOR plus at least 4.50% per annum (to be determined on the Pricing Date) on the Notes among interest on the Deposit and Put Premium, 3-Month USD LIBOR plus [●] percent constitutes interest on the Deposit and [●] 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 free writing prospectus.

We will not attempt to ascertain whether any of the entities whose stock is included in, or owned by, the relevant Reference Asset, as the case may be, 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 purposes. If one or more of the entities whose stock is included in, or owned by, the relevant Reference Asset, as the case may be, were so treated, certain adverse U.S. federal income tax consequences might apply. You should refer to information filed with the SEC and other authorities by the entities whose stock is included in, or owned by, the relevant Reference Asset, as the case may be, and consult your tax advisor regarding the possible consequences to you if one or more of the entities whose stock is included in, or owned by, the relevant Reference Asset, as the case may be, is or becomes a PFIC or a USRPHC.

Withholding and reporting requirements under the legislation enacted on March 18, 2010 (as discussed beginning on page S-48 of the prospectus supplement) will generally apply to payments made after December 31, 2013. However, this withholding tax will not be imposed on payments pursuant to obligations outstanding on January 1, 2014. Additionally, withholding due to any payment being treated as a “dividend equivalent” (as discussed beginning on page S-47 of the prospectus supplement) will begin no earlier than January 1, 2014. Holders are urged to consult with their own tax advisors regarding the possible implications of this recently enacted legislation on their investment in the Notes.

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.
