ADDITIONAL INFORMATION REGARDING OUR ESTIMATED VALUE OF THE NOTES

The range of the estimated values of the Notes referenced above may not correlate on a linear basis with the range of Maximum Returns set forth in this preliminary pricing supplement.  We determined the size of the range based on prevailing market conditions, as well as the anticipated duration of the marketing period for the Notes. The final terms for the Notes will be determined on the date the Notes are initially priced for sale to the public, which we refer to as the “Initial Valuation Date” based on prevailing market conditions on the Initial Valuation Date, and will be communicated to investors either orally or in a final pricing supplement.

Our internal pricing models take into account a number of variables and are based on a number of subjective assumptions, which may or may not materialize, typically including volatility, interest rates , and our internal funding rates.  Our internal funding rates (which are our internally published borrowing rates based on variables such as market benchmarks, our appetite for borrowing, and our existing obligations coming to maturity) may vary from the levels at which our benchmark debt securities trade in the secondary market.  Our estimated value on the Initial Valuation Date is based on our internal funding rates.  Our estimated value of the Notes may be lower if such valuation were based on the levels at which our benchmark debt securities trade in the secondary market.

Our estimated value of the notes on the Initial Valuation Date is expected to be less than the initial issue price of the Notes.  The difference between the initial issue price of the Notes and our estimated value of the Notes is expected to result from several factors, including 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.

Our estimated value on the Initial Valuation Date is not a prediction of the price at which the Notes may trade in the secondary market, nor will it be the price at which Barclays Capital Inc. may buy or sell the Notes in the secondary market. Subject to normal market and funding conditions, Barclays Capital Inc. or another affiliate of ours intends to offer to purchase the Notes in the secondary market but it is not obligated to do so.

Assuming that all relevant factors remain constant after Initial Valuation Date, the price at which Barclays Capital Inc. may initially buy or sell the Notes in the secondary market, if any, 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 on the Initial Valuation Date for a temporary period expected to be approximately six months after the initial issue date of the Notes because, in our discretion, we may elect to effectively reimburse to investors a portion of the estimated cost of hedging our obligations under the Notes and other costs in connection with the Notes which we will no longer expect to incur over the term of the Notes.  We made such discretionary election and determined this temporary reimbursement period on the basis of a number of factors, including the tenor of the Notes and any agreement we may have with the distributors of the Notes.  The amount of our estimated costs which we effectively reimburse to investors in this way may not be allocated ratably throughout the reimbursement period, and we may discontinue such reimbursement at any time or revise the duration of the reimbursement period after the initial issue date of the Notes based on changes in market conditions and other factors that cannot be predicted.

We urge you to read the “ Selected Risk Considerations ” beginning on page PPS-4 of this preliminary pricing supplement.

You may revoke your offer to purchase the Notes at any time prior to the Initial Valuation Date.  We reserve the right to change the terms of, or reject any offer to purchase, the Notes prior to their Initial Valuation Date.  In the event of any changes to the terms of the Notes, we will notify you and you will be asked to accept such changes in connection with your purchase.  You may also choose to reject such changes in which case we may reject your offer to purchase.

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 preliminary 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 examples below are based on a hypothetical Initial Level of 15,122.02 and a Maximum Return of 56.00%.  These examples do not take into account any tax consequences from investing in the Notes.

  *per $1,000 principal amount Note

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 an Initial Level of 15,122.02 to a Final Level of 16,634.22.

Because the Final Level of the Index is greater than the Initial Level but the Index Return of does not exceed the Maximum Return, 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 x Index Return]

$1,000 + [$1,000 x 10.00%] = $1,100.00

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

PPS-2

Example 2: The level of the Index increases from an Initial Level of 15,122.02 to a Final Level of 24,195.23.

Because the Index Return of 60.00% exceeds the Maximum Return, the investor will receive a payment at maturity of $1,560.00 per $1,000.00 principal amount Note, the maximum total payment on the Notes.

The total return on the investment of the Notes is 56.00%.

Example 3: The level of the Index decreases from an Initial Level of 15,122.02 to a Final Level of 12,097.62.

Because the Final Level of the Index is less than the Initial Level, the investor receives a payment at maturity of $1,000.00 per $1,000 principal amount Note.

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

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:

o                 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

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

·                   Exposure to U.S. Equities of the Dow Jones Industrial Average SM — The amount payable at maturity of the Notes is linked to the Dow Jones Industrial Average SM (the “Index”).  The Index is a price-weighted index comprised of 30 common stocks .  For additional information about the Index, see the information set forth under “Non-Proprietary Indices—Equity Indices— Dow Jones Industrial Average SM ” in the accompanying index supplement.

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.  In addition, this discussion applies to you only if you are an initial purchaser of the Notes; if you are a secondary purchaser of the Notes, the tax consequences to you may be different.

The following section is the opinion of our special tax counsel, Sullivan & Cromwell LLP, and it assumes that the description of the terms of the Notes in this free writing prospectus is materially correct.  The Notes will be treated as debt instruments subject to special rules governing contingent payment debt instruments for U.S. federal income tax purposes.  Under these rules, if you are a U.S. individual or taxable entity, you generally will be required to accrue interest on a current basis in respect of the Notes over their term based on the comparable yield for the Notes and pay tax accordingly, even though you will not receive any payments from us until maturity.  This comparable yield is determined solely to calculate the amount on which you will be taxed prior to maturity and is neither a prediction nor a guarantee of what the actual yield will be.  In addition, any gain you may recognize on the sale or maturity of the Notes would be taxed as ordinary interest income and any loss you may recognize on the sale or maturity of the Notes would generally be ordinary loss to the extent of the interest you previously included as income in respect of the Notes and thereafter would be capital loss.  If you are a noncorporate holder, you would generally be able to use such ordinary loss to offset your income only in the taxable year in which you recognize the ordinary loss and would generally not be able to carry such ordinary loss forward or back to offset income in other taxable years.

If you purchase your Notes for an amount that differs from the principal amount of the Notes, you may be subject to special tax rules as described in “Certain U.S. Federal Income Tax Considerations—U.S. Federal Income Tax Treatment of the Notes as Indebtedness for U.S. Federal Income Tax Purposes—Contingent Payment Debt Instruments” in the accompanying prospectus supplement (in particular, the rules that apply when a U.S. holder purchases a contingent payment debt instrument for an amount that differs from the adjusted issue price of that contingent payment debt instrument at the time of the purchase).  These rules are complex and therefore individuals are urged to consult their tax advisors regarding these rules.

For a further discussion of the tax treatment of your Notes, including information regarding obtaining the comparable yield for your Notes and the tax consequences to secondary purchasers of the Notes, please see the discussion under the heading “Certain U.S. Federal Income Tax Considerations—U.S. Federal Income Tax Treatment of the Notes as Indebtedness for U.S. Federal Income Tax Purposes—Contingent Payment Debt Instruments” in the accompanying prospectus supplement.

“Specified Foreign Financial Asset” Reporting.  Under legislation enacted in 2010, owners of “specified foreign financial assets” with an aggregate value in excess of $50,000 (and in some circumstances, a higher threshold) may be required to file an information report with respect to such assets with their tax returns.  “Specified foreign financial assets” generally include any financial accounts maintained by foreign financial institutions (which would include debt of a foreign financial institution that is not regularly traded on an established securities market, and accordingly may include your Notes), as well as any of the following, 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 issued guidance exempting “specified foreign financial assets” held in a financial account from reporting under this provision (although the financial account itself, if maintained by a foreign financial institution, may remain subject to this reporting requirement).  Holders are urged to consult their tax advisors regarding the application of this legislation to their ownership of the Notes.

Non-U.S. Holders .  Barclays currently does not withhold on payments treated as interest to non-U.S. holders in respect of instruments such as the Notes .  However, if Barclays determines that there is a material risk that it will be required to withhold on any such payments, Barclays may withhold on any payments at a 30% rate, unless you have provided to Barclays an appropriate and valid Internal Revenue Service Form W-8.  Non-U.S. holders will also be subject to the general rules regarding information reporting and backup withholding as described under the heading “Certain U.S. Federal Income Tax Considerations—Information Reporting and Backup Withholding—” in the accompanying prospectus supplement.

In addition, the Treasury Department has issued proposed regulations under Section 871(m) of the Internal Revenue Code which could ultimately require us to treat all or a portion of any payment in respect of your Notes as a “dividend equivalent” payment that is subject to withholding tax at a rate of 30% (or a lower rate under an applicable treaty).  You could also be required to make certain certifications in order to avoid or minimize such withholding obligations, and you could be subject to withholding (subject to your potential right to claim a refund from the Internal Revenue Service) if such certifications were not received or were not satisfactory.  You should consult your tax advisor concerning the potential application of these regulations to payments you receive with respect to the Notes when these regulations are finalized.

·                   “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”; and

·                   “Risk Factors—Additional Risks Relating to Notes Treated for U.S. Federal Income Tax Purposes as Contingent Payment Debt Instruments”.

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

·                   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.

·                   You Will Not Receive Any Interest or Periodic Coupon Payments; Your Return on the Notes Will be Limited to the Payment That You Receive at Maturity —Your return on the Notes (if any) is limited to the payment that you will receive at maturity, which is approximately seven years after the issue date.  You will not receive any payments on the Notes prior to the maturity date. If the Final Level of the Index is not greater than the Initial Level, the payment that you receive at maturity will be limited to the principal amount of your Notes.  The return at maturity of the principal amount of your Notes (plus any payment that you receive in excess thereof) may not compensate you for any loss in value due to inflation and other factors relating to the value of money over time.

Any payment due on the Notes, including the return of any principal due at maturity, is subject to the creditworthiness of the issuer, as described under “Credit of Issuer” above.

PPS-4

·                   Any Positive Return on the Notes Will Not Exceed 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 the Maximum Return multiplied by $1,000.  The Maximum Return will be set on the Initial Valuation Date and will not be less than 56.00%. Accordingly, assuming that the Maximum Return is set at 56.00%, the maximum possible payment that you may receive at maturity will be $1,560.00 per $1,000 principal amount Note that you hold.

·                   No Dividend Payments or Voting Rights —As a holder of the Notes, you will not receive interest payments, as described above, 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 (As Compared to the Initial Level) —The Final Level of the Index will be based solely on the Index Closing Level on the Final Valuation Date.  Therefore, if the level of the Index drops 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.

·                   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, 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.

PPS-5

·                   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.

·                   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:

o                 the expected volatility of the Index;

o                 the time to maturity of the Notes;

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

o                 interest and yield rates in the market generally;

o                 the supply and demand for the Notes;

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

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