Prospectus dated August 31, 2010:

Prospectus Supplement dated May 27, 2011:

Initial Price: $44.16

Barrier Price: $39.74 (90.00% of the hypothetical Initial Price set forth above, rounded to the nearest hundredth)

Upside Leverage Factor: 1.50

Maximum Return: 36.00%

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 with respect to the ETF as well as the consequences of that market disruption event, see “Reference Assets—Indices—Market Disruption Events for Securities with the Reference Asset Comprised of an ETF or Indices of Equity Securities”; and

For a description of further adjustments that may affect the ETF, see “Reference Assets—Indices—Adjustments Relating to Securities with the Reference Asset Comprised of an ETF”.

Exposure to the Japanese Equities of the ETF —The return on the Notes is linked to the performance of the ETF from the Initial Price to the Final Price, as described in this preliminary pricing supplement. The ETF seeks investment results that closely correspond to the price and yield performance, before fees and expenses, of the WisdomTree Japan Hedged Equity Index (the “ETF Underlying Index”). The ETF Underlying Index is designed to provide exposure to equity securities in Japan, while at the same time hedging exposure to fluctuation between the value of the U.S. dollar and the Japanese yen. For additional information regarding the ETF and the ETF Underlying Index, see the information set forth below under “Description of the ETF”.

Material U.S. Federal Income Tax Considerations — The material 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. Except as noted under “Non-U.S. Holders” below, 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 (for example, if you did not purchase your Notes in the initial issuance of the Notes).

“Risk Factors—Additional Risks Relating to Notes Which Are Not Characterized as Being Fully Principal Protected or Are Characterized as Being Partially Protected or Contingently Protected”;

“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.”

Your Investment May Result in a Loss; No Principal Protection —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 Final Price of the ETF is less than the Barrier Price, your Notes will be fully exposed to the decline in the ETF from the Initial Price to the Final Price and you will lose some or all of your investment in the Notes. You may lose up to 100% of the principal amount of your Notes.

Any Positive Return on the Notes Will Not Exceed the Maximum Return —The potential total return on the Notes is limited by the Maximum Return at maturity. Assuming that the Maximum Return is set at 36.00% on the Initial Valuation Date, the maximum payment at maturity that you may receive will be $1,360.00 per $1,000 principal amount Note that you hold. Also, given that the Upside Leverage Factor provides 200% exposure to any positive performance of the ETF, any increase in the Final Price of the ETF over the Initial Price of the ETF by more than 24.00% will not increase your return on the Notes.

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 depends on the ability of Barclays Bank PLC to satisfy its obligations as they come due and is not guaranteed by any third party. 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.

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

The Payment at Maturity of Your Notes is Not Based on the Level of the ETF at Any Time Other than the Final Price on the Final Valuation Date —The Final Price of the ETF and the Reference Asset Return will be based solely on the ETF Closing Price on the Final Valuation Date. Therefore, if the level of the ETF dropped precipitously on the Final Valuation Date, the payment at maturity, if any, that you will receive for your Notes may be significantly less than it would otherwise have been had the payment at maturity been linked to the level of the ETF prior to such drop.

Certain Features of Exchange-Traded Funds Will Impact the Value of the Notes — The value of the ETF is subject to:

The ETF May Underperform the ETF Underlying Index. The performance of an ETF may not replicate the performance of, and may underperform, its underlying index. Unlike the ETF 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 ETF 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 ETF Underlying Index or due to other circumstances. Because the return on your Notes is linked to the performance of the ETF and not to the ETF Underlying Index, the return on your Notes may be less than that of an alternative investment linked directly to ETF Underlying Index.

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 futures contracts, options on futures contracts, other types of options and swaps 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. 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.

Non-U.S. Securities Markets Risk —The stocks comprising the ETF are issued by Japanese companies which trade on the Japanese securities markets. These Japanese securities markets may have less liquidity and may be more volatile than U.S. or other securities markets and market development may affect Japanese markets differently from U.S. or other securities markets. Also, there is generally less publicly available information about Japanese companies listed on such markets than about those of U.S. companies that are subject to expansive reporting requirements of the U.S. Securities and Exchange Commission. Japanese companies are subject to accounting, auditing and financial standards and requirements that differ from those applicable to U.S. reporting companies. Additionally, securities prices in Japan are subject to political, economic, financial and social factors that apply in Japan. These factors, which could negatively affect the Japanese securities markets, include the possibility of recent or future changes in the Japanese government’s economic and fiscal policies, the possible imposition of, or changes in, currency exchange laws or other laws or restrictions applicable to Japanese companies or investments in Japanese equity securities and the possibility of fluctuations in the rate of exchange between the Japanese yen and the U.S. dollar, the possibility of outbreaks of hostility and political instability and the possibility of natural disasters or adverse public health developments in Japan or Asia. Moreover, the Japanese economy may differ favorably or unfavorably from the U.S. economy in important respects such as growth of gross national product, rate of inflation, capital reinvestment, resources and self-sufficiency.

Currency Exchange Rate Risk —The ETF invests in securities that are traded and quoted in a foreign currency, the Japanese yen. Therefore, holders of the Notes will be exposed to currency exchange rate risk with respect to the Japanese yen. In particular, the value of the Japanese yen may be subject to a high degree of fluctuation due to changes in interest rates, the effects of monetary policies issued by the United States, the Japanese government, central banks or supranational entities, the imposition of currency controls or other national or global political or economic developments. An investor’s net exposure will depend on the extent to which the Japanese yen strengthens or weakens against the U.S. dollar and the relative weight of each non-U.S. security in the portfolio of the ETF. If, taking into account such weighting, the U.S. dollar strengthens against the Japanese yen, the value of securities in which the ETF invests will be adversely affected and the value of the Notes may decrease. Please see “Currency Hedge Risk” below for more information.

Currency Hedge Risk —The ETF seeks investment results that closely correspond to the price and yield performance, before fees and expenses, of the ETF Underlying Index. The ETF Underlying Index provides exposure to Japanese equity markets while at the same time neutralizing exposure to fluctuations of the Japanese yen movements relative to the U.S. dollar. Constituent stocks are of companies within the WisdomTree Japan Dividend Index. The WisdomTree Japan Dividend Index “hedges” against fluctuations in the relative value of the Japanese yen against the U.S. dollar.

The Estimated Value of Your Notes Might be Lower if Such Estimated Value Were Based on the Levels at Which Our Debt Securities Trade in the Secondary Market . The estimated value of your Notes on the Initial Valuation Date is based on a number of variables, including our internal funding rates. Our internal funding rates may vary from the levels at which our benchmark debt securities trade in the secondary market. As a result of this difference, the estimated values referenced above may be lower if such estimated values were based on the levels at which our benchmark debt securities trade in the secondary market.

The Estimated Value of Your Notes is Expected to be Lower Than the Initial Issue Price of Your Notes . The estimated value of your Notes on the Initial Valuation Date is expected to be lower, and may be significantly lower, than the initial issue price of your Notes. The difference between the initial issue price of your Notes and the estimated value of the Notes is expected as a result of certain factors, such as any sales commissions expected to be paid to Barclays Capital Inc. or another affiliate of ours, any selling concessions, discounts, commissions or fees expected to be allowed or paid to non-affiliated intermediaries, the estimated profit that we or any of our affiliates expect to earn in connection with structuring the Notes, the estimated cost which we may incur in hedging our obligations under the Notes, and estimated development and other costs which we may incur in connection with the Notes.

The Estimated Value of the Notes is Based on Our Internal Pricing Models, Which May Prove to be Inaccurate and May be Different from the Pricing Models of Other Financial Institutions. The estimated value of your Notes on the Initial Valuation Date is based on our internal pricing models, which take into account a number of variables and are based on a number of subjective assumptions, which may or may not materialize. These variables and assumptions are not evaluated or verified on an independent basis. Further, our pricing models may be different from other financial institutions’ pricing models and the methodologies used by us to estimate the value of the Notes may not be consistent with those of other financial institutions which may be purchasers or sellers of Notes in the secondary market. As a result, the secondary market price of your Notes may be materially different from the estimated value of the Notes determined by reference to our internal pricing models.

The Estimated Value of Your Notes Is Not a Prediction of the Prices at Which You May Sell Your Notes in the Secondary Market, if any, and Such Secondary Market Prices, If Any, Will Likely be Lower Than the Initial Issue Price of Your Notes and Maybe Lower Than the Estimated Value of Your Notes. The estimated value of the Notes will not be a prediction of the prices at which Barclays Capital Inc., other affiliates of ours or third parties may be willing to purchase the Notes from you in secondary market transactions (if they are willing to purchase, which they are not obligated to do). The price at which you may be able to sell your Notes in the secondary market at any time will be influenced by many factors that cannot be predicted, such as market conditions (see “Many Economic and Market Factors Will Impact the Value of the Notes” below ) and any bid and ask spread for similar sized trades, and may be substantially less than our estimated value of the Notes. Further, as secondary market prices of your Notes take into account the levels at which our debt securities trade in the secondary market, and do not take into account our various costs related to the Notes such as fees, commissions, discounts, and the costs of hedging our obligations under the Notes, secondary market prices of your Notes will likely be lower than the initial issue price of your Notes. As a result, the price, at which Barclays Capital Inc., other affiliates of ours or third parties may be willing to purchase the Notes from you in secondary market transactions, if any, will likely be lower than the price you paid for your Notes, and any sale prior to the maturity date could result in a substantial loss to you.

The Temporary Price at Which We May Initially Buy The Notes in the Secondary Market And the Value We May Initially Use for Customer Account Statements, If We Provide Any Customer Account Statements At All, May Not Be Indicative of Future Prices of Your Notes. Assuming that all relevant factors remain constant after the Initial Valuation Date, the price at which Barclays Capital Inc. may initially buy or sell the Notes in the secondary market (if Barclays Capital Inc. makes a market in the Notes, which it is not obligated to do) and the value that we may initially use for customer account statements, if we provide any customer account statements at all, may exceed our estimated value of the Notes on the Initial Valuation Date, as well as the secondary market value of the Notes, for a temporary period after the initial issue date of the Notes. The price at which Barclays Capital Inc. may initially buy or sell the Notes in the secondary market and the value that we may initially use for customer account statements may not be indicative of future prices of your Notes.

We and Our Affiliates May Engage in Various Activities or Make Determinations That Could Materially Affect Your Notes in Various Ways and Create Conflicts of Interest. We and our affiliates establish the offering price of the Notes for initial sale to the public, and the offering price is not based upon any independent verification or valuation. Additionally, the role played by Barclays Capital Inc., as a dealer in the Notes, could present it with significant conflicts of interest with the role of Barclays Bank PLC, as issuer of the Notes. For example, Barclays Capital Inc. or its representatives may derive compensation or financial benefit from the distribution of the Notes and such compensation or financial benefit may serve as an incentive to sell these Notes instead of other investments. We may pay dealer compensation to any of our affiliates acting as agents or dealers in connection with the distribution of the Notes. Furthermore, we and our affiliates make markets in and trade various financial instruments or products for their own accounts and for the account of their clients and otherwise provide investment banking and other financial services with respect to these financial instruments and products. These financial instruments and products may include securities, instruments or assets that may serve as the underliers, basket underliers or constituents of the underliers of the Notes. Such market making, trading activities, other investment banking and financial services may negatively impact the value of the Notes. Furthermore, in any such market making, trading activities, and other services, we or our affiliates may take positions or take actions that are inconsistent with, or adverse to, the investment objectives of the holders of the Notes. We and our affiliates have no obligation to take the needs of any buyer, seller or holder of the Notes into account in conducting these activities.

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 make a secondary market for the Notes but are not required to do so, and may discontinue any such secondary market making at any time, without notice. Barclays Capital Inc. may at any time hold unsold inventory, which may inhibit the development of a secondary market for the Notes. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the Notes easily. 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. The Notes are not designed to be short-term trading instruments. Accordingly, you should be able and willing to hold your Notes to maturity.

Taxes —The U.S. 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 above. As discussed further in the accompanying prospectus supplement, the Internal Revenue Service issued a notice in 2007 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 and whether all or part of the gain you may recognize upon the sale or maturity of an instrument such as the Notes should be treated as ordinary income. Similarly, the Internal Revenue Service and the Treasury Department have current projects open with regard to the tax treatment of pre-paid forward contracts and contingent notional principal contracts. While it is impossible to anticipate how any ultimate guidance would affect the tax treatment of instruments such as the Notes (and while any such guidance may be issued on a prospective basis only), such guidance could be applied retroactively and could in any case increase the likelihood that you will be required to accrue income 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. The outcome of this process is uncertain. 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 level of the ETF, 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 time to maturity of the Notes;

the dividend rate on the common stocks underlying the ETF;

interest and yield rates in the market generally;

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

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