Issue Date:	July 21, 2011
Final Valuation Date:	January 18, 2013 *
Maturity Date:	January 24, 2013 **
Denominations:	Minimum denomination of $1,000, and integral multiples of $1,000 in excess thereof
Reference Asset:	Russell 2000® Index (the “Index”) (Bloomberg ticker symbol “RTY <Index>”)
Maximum Return:	19.80%
Upside Leverage Factor:	2.00
Buffer Percentage:	10.00%
Payment at Maturity:	If the Index Return is greater than 0%, you will receive a cash payment (subject to our credit risk) that provides you with a return equal to the Index Return multiplied by the Upside Leverage Factor, subject to the Maximum Return on the Notes. For example, with the Maximum Return equal to 19.80%, if the Index Return is 9.90% or more, you will receive the Maximum Return on the Notes of 19.80%, which entitles you to the maximum total payment of $1,198.00 for every $1,000 principal amount Note that you hold. Accordingly, if the Index Return is positive, your payment per $1,000 principal amount Note will be calculated as follows, subject to the Maximum Return: $1,000 + [$1,000 × (Index Return × Upside Leverage Factor)] If the Index Return is less than or equal to 0% and equal to or greater than -10%, you will receive the principal amount of your Notes; and If the Index Return is less than -10%, you will receive a cash payment (subject to our credit risk) equal to (a) the principal amount of your Notes plus (b) the principal amount of your Notes multiplied by the sum of (x) Index Return and (y) the Buffer Percentage, calculated per $1,000 principal amount Note as follows: $1,000 + [$1,000 × (Index Return + 10%)] If the Index declines by more than 10% from the Initial Level to the Final Level, you will lose 1% of the principal amount of your Notes for every 1% that the Index Return falls below -10%. You may lose up to 90% of your principal. Any payment on the Notes, including any principal protection feature, is subject to the creditworthiness of the Issuer and is not guaranteed by any third party. For a description of risks with respect to the ability of Barclays Bank PLC to satisfy its obligations as they come due, see “Credit of Issuer” in this pricing supplement.

In certain circumstances, the closing level of the Index will be based on the alternate calculation of the Index as described in “Reference Assets—Adjustments Relating to Securities with the Reference Asset Comprised of an Index or Indices” starting on page S-90 of the accompanying Prospectus Supplement.
Calculation Agent:	Barclays Bank PLC
CUSIP/ISIN:	06738KMP3 and US06738KMP39

What is the Total Return on the Notes at Maturity Assuming a Range of Performance for the Index?

The following table illustrates the hypothetical total return at maturity on the Notes. The “total return” as used in this pricing supplement is the number, expressed as a percentage, that results from comparing the payment at maturity per $1,000 principal amount Note to $1,000. The hypothetical total returns set forth below are for illustrative purposes only and may not be the actual total returns applicable to a purchaser of the Notes. The numbers appearing in the following table and examples have been rounded for ease of analysis. The hypothetical total returns set forth below are based on the Initial Level of 815.97 and the Maximum Return of 19.80%. These examples do not take into account any tax consequences from investing in the Notes.

Hypothetical Examples of Amounts Payable at Maturity

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

Example 1: The level of the Index increases from the Initial Level of 815.97 to a Final Level of 856.77.

Because the hypothetical Index Return of 5.00% multiplied by the Upside Leverage Factor of 2.00 does not exceed the Maximum Return of 19.80%, the investor receives a payment at maturity of $1,100.00 per $1,000.00 principal amount Note calculated as follows:

$1,000 + [$1,000 × (5.00% × 2.00)] = $1,100.00

The total return on the investment of the Notes is 10.00%.

Example 2: The level of the Index decreases from the Initial Level of 815.97 to a Final Level of 775.17.

Because the hypothetical Final Level of 775.17 is less than the Initial Level of 815.97 by a percentage equal to or less than the Buffer Percentage of 10.00%, the investor will receive a payment at maturity of $1,000.00 per $1,000.00 principal amount Note.

The total return on the investment of the Notes is 0.00%.

Example 3: The level of the Index increases from the Initial Level of 815.97 to a Final Level of 897.57.

Because the hypothetical Index Return of 10.00% multiplied by the Upside Leverage Factor of 2.00 exceeds the Maximum Return of 19.80%, the investor will receive a payment at maturity of $1,198.00 per $1,000.00 principal amount Note, the maximum total payment on the Notes.

The total return on the investment of the Notes is 19.80%.

Example 4: The level of the Index decreases from the Initial Level of 815.97 to a Final Level of 571.18.

Because the hypothetical Final Level of 571.18 is less than the Initial Level of 815.97 by more than the Buffer Percentage of 10.00%, the investor will receive a payment at maturity of $800.00 per $1,000.00 principal amount Note calculated as follows:

$1,000 + [$1,000 × (-30% + 10%)] = $800.00

The total return on the investment of the Notes is -20%.

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 with respect to the Index 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 Index or Indices of Equity Securities”; and

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

• Appreciation Potential—The Notes provide the opportunity to enhance equity returns up to the Maximum Return on the Notes, or a maximum additional payment, for every $1,000 principal amount Note, of $198.00, which is equal to $1,000 multiplied by the Maximum Return. 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 and is not guaranteed by any third party.

• Limited Protection Afforded by the Buffer Percentage—If the Index Return is negative, the payment at maturity of the Notes will depend on the extent to which the Final Level of the Index declines from the Initial Level of the Index. If the Final Level declines from the Initial Level by more than 10%, you will lose an amount equal to 1% of the principal amount of your Notes for every 1% that the Index Return falls below -10%. Any payment on the Notes, including any principal protection feature, is subject to the creditworthiness of the Issuer and is not guaranteed by any third party. For a description of risks with respect to the ability of Barclays Bank PLC to satisfy its obligations as they come due, see “Credit of Issuer” in this pricing supplement.

PS-4

• Exposure to the U.S. Equities of the Russell 2000^® Index—The return on the Notes is linked to the Russell 2000^® Index. The Russell 2000^® Index is designed to track the performance of the small capitalization segment of the U.S. equity market. For additional information about the Index, see the information set forth under “Non-Proprietary Indices—Equity Indices—Russell 2000^® Index” in the index supplement.

• 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 (for example, if you did not purchase your Notes in the initial issuance of the Notes).

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 Index. 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.

In the opinion of our special tax counsel, Sullivan & Cromwell LLP, it would be reasonable to treat your Notes in the manner described above. This opinion assumes that the description of the terms of the Notes in this pricing supplement 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 pricing supplement.

Recently Enacted Legislation. Under recently enacted legislation, individuals that own “specified foreign financial assets” with an aggregate value in excess of $50,000 are generally required to file an information report with respect to such assets with their tax returns. “Specified foreign financial assets” include any financial accounts maintained by foreign financial institutions, as well as any of the following (which may include your Notes), but only if they are not held in accounts maintained by financial institutions: (i) stocks and securities issued by non-U.S. persons, (ii) financial instruments and contracts held for investment that have non-U.S. issuers or counterparties and (iii) interests in foreign entities. The Internal Revenue Service has suspended this filing requirement for tax returns that are filed before it issues the form on which to report the relevant information. However, once the Internal Revenue Service issues the form, taxpayers that were not required to report in prior years because of the suspension will nevertheless be required to report the relevant information for such prior years on such form. Individuals are urged to consult their tax advisors regarding the application of this legislation to their ownership of the Notes.

Selected Risk Considerations

An investment in the Notes involves significant risks. Investing in the Notes is not equivalent to investing directly in the Index. 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”;

• “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 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.”

PS-5

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 Index and will depend on whether, and the extent to which, the Index Return is positive or negative, whether the Index Return times the Upside Leverage Factor exceeds the Maximum Return and whether the Index Return falls below -10%. If the Index Return falls below -10%, you will lose 1% of the principal amount of your Notes for every 1% that the Index Return falls below -10%. You may lose up to 90% of your principal.

• Your Maximum Gain on the Notes Is Limited to the Maximum Return—If the Index Return is greater than 0%, for each $1,000 principal amount Note, you will receive at maturity $1,000 plus an additional amount that will not exceed $198.00, which is the Maximum Return multiplied by $1,000.

• 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 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 Index would have.

• The Payment at Maturity of Your Notes is Not Based on the Level of the Index at Any Time Other than the Final Level on the Final Valuation Date—The Index Return will be based solely on the Final Level of the Index on the Final Valuation Date (subject to adjustments as described in the prospectus supplement) as compared to the Initial Level. Therefore, if the level of the Index fell 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 such payment been linked to the level of the Index prior to such drop.

• 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 pricing supplement 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 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.

• 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 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, 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 level of the Index 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 Index;

• the time to maturity of the Notes;

• the dividend rate on the common stocks underlying the Index;

• 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.
