Free Writing Prospectus (To the Prospectus dated February 10, 2009, the Prospectus Supplement dated March 1, 2010) Filed Pursuant to Rule 433 Registration No. 333-145845 April 6, 2010

Buffered SuperTrack^SM Notes   Global Medium-Term Notes, Series A

There are two separate offerings of Buffered SuperTrack^SM Notes (the “Notes”) issued by Barclays Bank PLC. Common terms used in all offerings are described below. The specific terms for each offering are listed in the table below. Terms used in this free writing prospectus, but not defined herein, shall have the meanings ascribed to them in the prospectus supplement. The purchaser of a Note will acquire a security linked to the performance of a single ETF (not a basket of ETFs). THE NOTES DO NOT GUARANTEE ANY RETURN OF PRINCIPAL AT MATURITY.

The following terms are common to each separate Notes offering:

Issuer: Barclays Bank PLC (Rated AA-/Aa3^‡)

Initial Valuation Date: April 27, 2010

Issue Date: April 30, 2010

Denominations: Minimum denomination of $1,000, and integral multiples of $1,000 in excess thereof.

Payment at Maturity: For each Notes offering, if the final price is greater than or equal to the initial price, you will receive a cash payment at maturity equal to (1) the principal amount of your Notes, plus (2) (a) the principal amount of your Notes times (b) the product of the reference asset return and the participation rate, subject to the maximum return, if any. Accordingly, if the reference asset return is positive or equal to zero, your payment per $1,000 principal amount Note, subject to the maximum return, if any, will be:

$1,000 + [$1,000 × (Reference Asset Return x Participation Rate)]

Your principal is protected at maturity against a decline in the closing price of the Reference Asset from the initial valuation date to the final valuation date by a percentage up to the buffer percentage at maturity. If the final price has declined from the initial price by the buffer percentage or less, you will receive a payment at maturity equal to the principal amount of your Notes.

If the final price has declined from the initial price by more than the buffer percentage, you will receive a cash payment equal to (a) the principal amount of your Notes plus (b) the principal amount of your Notes multiplied by the sum of (i) the reference asset return and (ii) the buffer percentage:

$1,000 + [$1,000 x (Reference Asset Return + Buffer Percentage)]

Loss Percentage: One minus Buffer Percentage

You will lose up to the loss percentage of your investment at maturity if the final price declines from the initial price by more than the buffer percentage.

Reference Asset Return: For each Notes offering, the performance of the Reference Asset to which such Notes offering is linked from the initial to the final valuation date, calculated as follows:

Final Price – Initial Price

Initial Price

Initial Price: For each Notes offering, the closing price of the applicable Reference Asset on the initial valuation date, as indicated in the table below.

Final Price: For each Notes offering, the closing price of the applicable Reference Asset on the final valuation date.

Calculation Agent: Barclays Bank PLC

^‡ The Notes are not rated by Standard & Poor’s Ratings Services (“S&P”) or Moody’s Investors Service (“Moody’s”) as a result of certain policy changes by these organizations. As announced in December 2009, S&P no longer rates obligations, such as the Notes, with variable principal payments linked to commodity prices, equity prices or indices linked to either commodity or equity prices. However, the other senior unsecured debt securities of a maturity of more than one year of Barclays Bank PLC unaffected by this policy change are rated AA- by S&P. In addition, as announced in June 2009, Moody’s no longer issues public ratings of notes, such as the Notes, for which repayment of principal is dependent on the occurrence of a non-credit event. However, the other senior unsecured debt securities of Barclays Bank PLC unaffected by this policy change are rated Aa3 by Moody’s. The ratings mentioned in this paragraph are subject to downward revision, suspension or withdrawal at any time by the assigning rating organization and are not a recommendation to buy, sell or hold securities.

* Subject to postponement in the event of a market disruption event and as described under “Reference Assets—Exchange-Traded Funds—Market Disruption Events for Securities with the Reference Asset Comprised of Shares or Other Interests in an Exchange-Traded Fund or Exchange-Traded Funds” in the prospectus supplement.

^† The actual participation rate, buffer percentage and maximum return, as the case may be, on the Notes will be set on the initial valuation date, but will not be less than the respective percentage or the lower end of the percentage range, as applicable, set forth in the table above.

Investing in the Notes involves a number of risks. See “Risk Factors” beginning on page S-5 of the prospectus supplement and “Selected Risk Considerations” beginning on page FWP-2 of this free writing prospectus.

The Notes will not be listed on any U.S. securities exchange or quotation system. Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined that this free writing prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The Notes constitute our direct, unconditional, unsecured and unsubordinated obligations and are not deposit liabilities of Barclays Bank PLC and are not insured by the U.S. Federal Deposit Insurance Corporation or any other governmental agency of the United States, the United Kingdom or any other jurisdiction.

ADDITIONAL TERMS SPECIFIC TO THE NOTES

You should read this free writing prospectus together with the prospectus dated February 10, 2009, as supplemented by the prospectus supplement dated March 1, 2010 relating to our Global Medium-Term Notes, Series A, of which these Notes are a part. This free writing prospectus, together with the documents listed below, contains the terms of the Notes and supersedes all prior or contemporaneous oral statements as well as any other written materials including preliminary or indicative pricing terms, correspondence, trade ideas, structures for implementation, sample structures, brochures or other educational materials of ours. You should carefully consider, among other things, the matters set forth in “Risk Factors” in the prospectus supplement, 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.

You may access these documents on the SEC website at www.sec.gov as follows (or if such address has changed, by reviewing our filings for the relevant date on the SEC website):

Our SEC file number is 1-10257. As used in this free writing prospectus, the “Company,” “we,” “us,” or “our” refers to Barclays Bank PLC.

PROGRAM CREDIT RATING

The Notes are not rated by Standard & Poor’s Ratings Services (“S&P”) or Moody’s Investors Service (“Moody’s”) as a result of certain policy changes by these organizations. As announced in December 2009, S&P no longer rates obligations, such as the Notes, with variable principal payments linked to commodity prices, equity prices or indices linked to either commodity or equity prices. However, the other senior unsecured debt securities of a maturity of more than one year of Barclays Bank PLC unaffected by this policy change are rated AA- by S&P. An AA rating from S&P generally indicates that the issuer’s capacity to meet its financial commitment on the obligations is very strong. In addition, as announced in June 2009, Moody’s no longer issues public ratings of notes, such as the Notes, for which repayment of principal is dependent on the occurrence of a non-credit event. However, the other senior unsecured debt securities of Barclays Bank PLC unaffected by this policy change are rated Aa3 by Moody’s. An Aa3 rating by Moody’s indicates that the rated securities are currently judged by Moody’s to be obligations of high quality and are subject to very low credit risk. The ratings mentioned in this paragraph are a statement of opinion and not a statement of fact and are subject to downward revisions, suspension or withdrawal at any time by the assigning rating agency and are not a recommendation to buy, sell or hold securities.

Selected Risk Considerations

An investment in the Notes involves significant risks. Investing in the Notes is not equivalent to investing directly in the ETF. These risks are explained in more detail in the “Risk Factors” section of the prospectus supplement, including the risk factors discussed under the following headings:

• “Risk Factors—Risks Relating to All Securities”;

FWP-2

• “Risk Factors—Additional Risks Relating to Notes Which Pay No Interest”; and

• “Risk Factors—Additional Risks Relating to Securities with Reference Assets That Are Equity Securities or Shares or Other Interests in Exchange-Traded Funds, That Contain Equity Securities or Shares or Other Interests in Exchange-Traded Funds or That Are Based in Part on Equity Securities or Shares or Other Interests in Exchange-Traded Funds.”

In addition to the risks described above, you should consider the following:

• Your Investment in the Notes May Result in a Loss—The Notes do not guarantee any return of principal. The return on the Notes at maturity is linked to the performance of the ETF and will depend on whether, and the extent to which, the reference asset return is positive or negative. If the applicable ETF declines by more than the buffer percentage, you will lose 1% of the principal amount of your Notes for every 1% decline beyond the buffer percentage. You may lose up to the loss percentage of your initial investment.

• Your Maximum Gain on the Notes Is Limited to the Maximum Return—If the final price is greater than the initial price, for each $1,000 principal amount Note, you will receive a payment at maturity of $1,000 plus an additional amount that will not exceed a predetermined percentage of the principal amount, regardless of the appreciation in the ETF, which may be significant. We refer to this percentage as the maximum return, which will be set on the initial valuation date and will not be less than the percentage indicated on the cover of this free writing prospectus as applicable to such Notes offering.

• Credit of Issuer—The Notes are senior unsecured debt obligations of the issuer, Barclays Bank PLC and are not, either directly or indirectly, an obligation of any third party. Any payment to be made on the Notes, including any principal protection provided at maturity, depends on the ability of Barclays Bank PLC to satisfy its obligations as they come due. In the event Barclays Bank PLC were to default on its obligations, you may not receive any amounts owed to you under the terms of the Notes.

• Real Estate Investment Risks—The iShares^® Dow Jones U.S. Real Estate Index Fund invests in companies that invest in real estate (“Real Estate Companies”), such as REITs or real estate holding companies. Real estate is highly sensitive to general and local economic conditions and developments, and characterized by intense competition and periodic overbuilding. Real Estate Companies may lack diversification due to ownership of a limited number of properties and concentration in a particular geographic region or property type. Rising interest rates could result in higher costs of capital for Real Estate Companies, which could negatively impact a Real Estate Company’s ability to meet its payment obligations. Real Estate Companies may use leverage (and some may be highly leveraged), which increases investment risk and the risks normally associated with debt financing and could adversely affect a Real Estate Company’s operations and market value in periods of rising interest rates. Investing in Real Estate Companies may involve risks similar to those associated with investing in small capitalization companies. There may be less trading in Real Estate Company shares. Real estate is relatively illiquid and, therefore, a Real Estate Company may have a limited ability to vary or liquidate properties in response to changes in economic or other conditions. Real Estate Companies may be subject to risks relating to functional obsolescence or reduced desirability of properties; extended vacancies due to economic conditions and tenant bankruptcies; catastrophic events such as earthquakes, hurricanes and terrorist acts; and casualty or condemnation losses. Real estate income and values also may be greatly affected by demographic trends, such as population shifts or changing tastes and values, or increasing vacancies or declining rents resulting from legal, cultural, technological, global or local economic developments. The prices of real estate company securities may drop because of the failure of borrowers to repay their loans, poor management, and the inability to obtain financing either on favorable terms or at all. Real estate income and values may be adversely affected by such factors as applicable domestic and foreign laws (including tax laws). Government actions, such as tax increases, zoning law changes or environmental regulations, also may have a major impact on real estate.

• The stocks of companies in the energy sector are subject to swift price and supply fluctuations—The companies the stocks of which are components of the index underlying the Energy Select Sector SPDR Fund develop and produce crude oil and natural gas and provide drilling and other energy resources production and distribution related services. Stock prices for these types of companies are affected by supply and demand both for their specific product or service and for energy products in general. The price of oil and gas, exploration and production spending, government regulation, world events and economic conditions will likewise affect the performance of these companies. Correspondingly, the stocks of companies in the energy sector are subject to swift price and supply fluctuations caused by events relating to international politics, energy conservation, the success of exploration projects, and tax and other governmental regulatory policies. Weak demand for the companies’ products or services or for energy products and services in general, as well as negative developments in these other areas, would adversely impact the value of stocks for such companies, and therefore the price of the Energy Select Sector SPDR Fund and the value of the Notes.

• No Interest or Dividend Payments or Voting Rights—As a holder of the Notes, you will not receive interest payments, and you will not have voting rights or rights to receive cash dividends or other distributions or other rights that holders of the ETF would have.

• 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 cost of hedging our obligations under the Notes through one or more of

FWP-3

our affiliates. As a result, the price, if any, at which Barclays Capital Inc. and other affiliates of Barclays Bank PLC will be willing to purchase Notes from you in secondary market transactions 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.

• Lack of Liquidity—The Notes will not be listed on any securities exchange. Barclays Capital Inc. and other affiliates of Barclays Bank PLC intend to offer to purchase the Notes in the secondary market but are not required to do so. 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 Barclays Capital Inc. and other affiliates of Barclays Bank PLC are willing to buy the Notes.

• Certain Features of Exchange-Traded Funds Will Impact the Value of the Notes—The performance of the ETF does not fully replicate the performance of the Underlying Index, and the ETF may hold securities not included in the Underlying Index. The value of the ETF to which your Notes is linked is subject to:

• Management risk. This is the risk that the investment strategy for the ETF, the implementation of which is subject to a number of constraints, may not produce the intended results.

• Derivatives risk. The ETF may invest in stock index futures contracts and other derivatives. A derivative is a financial contract, the value of which depends on, or is derived from, the value of an underlying asset such as a security or an index. Compared to conventional securities, derivatives can be more sensitive to changes in interest rates or to sudden fluctuations in market prices, and thus the ETF’s losses, and, as a consequence, the losses of your Notes, may be greater than if the ETF invested only in conventional securities.

• The ETF May Underperform the Underlying Index—The performance of the ETF may not replicate the performance of, and may underperform, the Underlying Index. Unlike the Underlying Index, the ETF will reflect transaction costs and fees that will reduce its relative performance. Moreover, it is also possible that the ETF may not fully replicate or may, in certain circumstances, diverge significantly from the performance of the Underlying Index; for example, due to the temporary unavailability of certain securities in the secondary market, the performance of any derivative instruments contained in the ETF, differences in trading hours between the ETF and the Underlying Index or due to other circumstances. Because the payment due at maturity of your Notes is linked to the performance of the ETF and not the Underlying Index, the return on your securities may be less than that of an alternative investment linked directly to the Underlying Index.

• Potential Conflicts—We and our 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.

• Taxes—The federal income tax treatment of the Notes is uncertain and the Internal Revenue Service could assert that the Notes should be taxed in a manner that is different than described below. As discussed further in the accompanying prospectus supplement, on December 7, 2007, the Internal Revenue Service issued a notice indicating that it and the Treasury Department are actively considering whether, among other issues, you should be required to accrue interest over the term of an instrument such as the Notes even though you will not receive any payments with respect to the Notes until maturity and whether all or part of the gain you may recognize upon the sale or maturity of an instrument such as the Notes could be treated as ordinary income. The outcome of this process is uncertain and could apply on a retroactive basis. You should consult your tax advisor as to the possible alternative treatments in respect of the Notes.

• Many Economic and Market Factors Will Impact the Value of the Notes—In addition to the price of the ETF on any day, the value of the Notes will be affected by a number of economic and market factors that may either offset or magnify each other, including:

• the expected volatility of the ETF, the Underlying Index and securities comprising the Underlying Index;

• the time to maturity of the Notes;

• the dividend rate underlying the ETF;

• interest and yield rates in the market generally;

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

• the exchange rate and the volatility of the exchange rate between the U.S. dollar and currencies in which the stocks underlying the ETF are denominated;

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

Selected Purchase Considerations

• Market Disruption Events and Adjustments—The final valuation date, the maturity date and the payment at maturity are subject to adjustment as described in the following sections of the prospectus supplement:

• For a description of what constitutes a market disruption event as well as the consequences of that market disruption event, see “Reference Assets—Exchange-Traded Funds—Market Disruption Events for Securities with the Reference Asset Comprised of Shares or Other Interests in an Exchange-Traded Fund or Exchange-Traded Funds” with respect to the reference asset; and

FWP-4

• For a description of further adjustments that may affect the reference asset, see “Reference Assets—Equity Exchange-Traded Fund—Share Adjustments Relating to Securities with the Reference Asset Comprised of an Exchange-Traded Fund or Exchange-Traded Funds”.

• Appreciation Potential—The Notes provide the opportunity to enhance returns by multiplying a positive reference asset return by the participation rate, up to the maximum return, if any. The actual participation rate and the actual maximum return on the Notes, if any, will be set on the initial valuation date and will not be less than the respective percentage or the lower end of the percentage range, as applicable, indicated on the cover of this free writing prospectus for the applicable Notes offering. Because the Notes are our senior unsecured obligations, payment of any amount at maturity is subject to our ability to pay our obligations as they become due.

• Limited Protection Against Loss—Payment at maturity of the principal amount of the Notes is protected against a decline in percentage terms in the final price, as compared to the initial price, of up to the buffer percentage. If the final price declines in percentage terms by more than the buffer percentage, you will lose 1% of the principal amount of your Notes for every 1% decline in the ETF beyond the buffer percentage.

• Certain U.S. Federal Income Tax Considerations—Some of the tax consequences of your investment in the Notes are summarized below. The discussion below supplements the discussion under “Certain U.S. Federal Income Tax Considerations” in the accompanying prospectus supplement. As described in the prospectus supplement, this section applies to you only if you are a U.S. holder (as defined in the accompanying prospectus supplement) and you hold your Notes as capital assets for tax purposes and does not apply to you if you are a member of a class of holders subject to special rules or are otherwise excluded from the discussion in the prospectus supplement.

The United States federal income tax consequences of your investment in the Notes are uncertain and the Internal Revenue Service could assert that the Notes should be taxed in a manner that is different than described below. Pursuant to the terms of the Notes, Barclays Bank PLC and you agree, in the absence of a change in law or an administrative or judicial ruling to the contrary, to characterize your Notes as a pre-paid cash-settled executory contract with respect to the applicable ETF. Subject to the discussion of Section 1260 below, if your Notes are so treated, you should generally recognize capital gain or loss upon the sale or maturity of your Notes in an amount equal to the difference between the amount you receive at such time and the amount you paid for your Notes. Such gain or loss should generally be long-term capital gain or loss if you have held your Notes for more than one year.

Although not entirely clear, it is possible that the purchase and ownership of the Notes could be treated as a “constructive ownership transaction” with respect to the applicable ETF that is subject to the constructive ownership rules of Section 1260 of the Internal Revenue Code. If any or all of your Notes were subject to the constructive ownership rules, then any long-term capital gain that you realize upon the sale or maturity of such Notes that is attributable to the appreciation of the shares of the applicable ETF over the term of the relevant Notes would be recharacterized as ordinary income (and you would be subject to an interest charge on deferred tax liability with respect to such capital gain) to the extent that such capital gain exceeds the amount of long-term capital gain that you would have realized had you purchased the actual shares of the applicable ETF on the date that you purchased the relevant Notes and sold the applicable ETF shares on the date of the sale or maturity of the relevant Notes (the “Excess Gain Amount”). Because the maturity payment under the Notes will only reflect the appreciation or depreciation in the value of the shares of the applicable ETF and will not be determined by reference to any short-term capital gains or ordinary income, if any, that is recognized by holders of shares of the applicable ETF, we believe that it is more likely than not that the Excess Gain Amount will be equal to zero, and that the application of the constructive ownership rules will accordingly not have any adverse effects to you. Because the application of the constructive ownership rules is unclear, however, you are strongly urged to consult your tax advisor with respect to the possible application of the constructive ownership rules to your investment in the Notes.

In the opinion of our special tax counsel, Sullivan & Cromwell LLP, the Notes should be treated in the manner described above. This opinion assumes that the description of the terms of the Notes in this free writing prospectus is materially correct.

As discussed further in the accompanying prospectus supplement, the Treasury Department and the Internal Revenue Service are actively considering various alternative treatments that may apply to instruments such as the Notes, possibly with retroactive effect.

For a further discussion of the tax treatment of your Notes as well as possible alternative characterizations, please see the discussion under the heading “Certain U.S. Federal Income Tax Considerations—Certain Notes Treated as Forward Contracts or Executory Contracts” in the accompanying prospectus supplement. You should consult your tax advisor as to the possible alternative treatments in respect of the Notes. For additional, important considerations related to tax risks associated with investing in the Notes, you should also examine the discussion in “Selected Risk Considerations—Taxes”, in this free writing prospectus.

Hypothetical Examples of Amounts Payable at Maturity for Notes linked to the iShares® Dow Jones U.S. Real Estate Index Fund

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

Example 1: The price of the Reference Asset increases from an initial price of $50.23 to a final price of $51.49.

Because the final price of $51.49 is greater than the initial price of $50.23 and the reference asset return of 2.50% multiplied by the participation rate does not exceed the maximum return of 14.75%, the investor receives a payment at maturity of $1,050.00 per $1,000.00 principal amount Note calculated as follows:

$1,000 + [$1,000 × (2.50% × 200%)] = $1,050.00

The total return on the investment of the Notes is 5.00%.

Example 2: The closing price of the Reference Asset decreases from an initial price of $50.23 to a final price of $47.72.

Because the final price of $47.72 declines from the initial price of $50.23 by less than the buffer percentage of 10%, the investor will receive a payment at maturity of $1,000.00 per $1,000.00 principal amount Note.

Example 3: The price of the Reference Asset increases from an initial price of $50.23 to a final price of $60.28.

Because the final price of $60.28 is greater than the initial price of $50.23 and the reference asset return of 20.00% multiplied by the participation rate is greater than the maximum return of 14.75%, the investor receives a payment at maturity of $1,147.50 per $1,000.00 principal amount Note, the maximum total payment on the Notes.

Example 4: The price of the Reference Asset decreases from the initial price of $50.23 to a final price of $37.67.

Because the final price of $37.67 is less than the initial price of $50.23% by more than the buffer percentage of 10%, the reference asset return is negative and the investor will receive a payment at maturity of $850.00 per $1,000.00 principal amount Note calculated as follows:

$1,000 + [$1,000 × (-25% + 10%)] = $850

The total return on the investment of the Notes is -15%.
