ADDITIONAL INFORMATION REGARDING OUR ESTIMATED VALUE OF 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 pricing 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 three months after the Issue Date 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-7 of this preliminary pricing supplement.

You may revoke your offer to purchase the Notes at any time prior to Initial Valuation Date. We reserve the right to change the terms of, or reject any offer to purchase, the Notes prior to the 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.

CONSENT TO U.K. BAIL-IN POWER

Under the U.K. Banking Act 2009, as recently amended, the relevant U.K. resolution authority may exercise a U.K. Bail-in Power under certain conditions which, in summary, include that such authority determines that: (i) a relevant entity (such as the issuer) is failing or is likely to fail, (ii) it is not reasonably likely that (ignoring the other stabilization powers under the U.K. Banking Act) any other action will be taken to avoid the entity’s failure, (iii) the exercise of the stabilization powers are necessary taking into account certain public interest considerations such as the stability of the U.K. financial system, public confidence in the U.K. banking system and the protection of depositors and (iv) the objectives of the resolution measures would not be met to the same extent by the winding up of the entity. Notwithstanding these conditions, there remains uncertainty regarding how the relevant U.K. resolution authority would assess these conditions in deciding whether to exercise any U.K. Bail-in Power. The U.K. Bail-in Power includes any statutory write-down and conversion power, which allows for the cancellation of all, or a portion, or any amounts payable on the notes, including the repayment of principal and/or the conversion of all, or a portion, of any amounts payable on the notes, including the repayment of principal, into shares or other securities or other obligations of ours or another person, including by means of a variation to the terms of the notes. Accordingly, if any U.K. Bail-in Power is exercised you may lose all or a part of the value of your investment in the Notes or receive a different security, which may be worth significantly less than the Notes and which may have significantly fewer protections than those typically afforded to debt securities. Moreover, the relevant U.K. resolution authority may exercise its authority to implement the U.K. Bail-in Power without providing any advance notice to the holders of the Notes.

By your acquisition of the Notes, you acknowledge, agree to be bound by, and consent to the exercise of any U.K. Bail-in Power by the relevant U.K. resolution authority.

This is only a summary. For more information, please see “Selected Risk Considerations—You May Lose Some or All of Your Investment If Any U.K. Bail-in Power Is Exercised by the Relevant U.K. Resolution Authority” in this preliminary pricing supplement and the full definition of “U.K. Bail-in Power” as well as the risk factors in the accompanying prospectus addendum.

HYPOTHETICAL EXAMPLES OF AMOUNTS PAYABLE AT MATURITY

The following table illustrates the hypothetical total return on the Notes under various circumstances. 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 and do not take into account any tax consequences from investing in the Notes. The hypothetical examples below also make the following key assumptions:

• Initial Level: 100.00*

• Upside Leverage Factor: 1.84

• Maximum Return: 70.012%

* The hypothetical Initial Level of 100.00 has been chosen for illustrative purposes only and do not represent a likely actual Initial Level for the Index. The actual Initial Level will be equal to the Index Closing Level on the Initial Valuation Date. The Index Closing Level on March 13, 2015 was 396.61. For more information about recent levels of the Index, please see “Information Regarding the Index” below.

Final Level	Index Return	Payment at Maturity**	Total Return on Notes
150.00	50.00%	$1,700.12	70.012%
140.00	40.00%	$1,700.12	70.012%
138.05	38.05%	$1,700.12	70.012%
130.00	30.00%	$1,552.00	55.20%
120.00	20.00%	$1,368.00	36.80%
110.00	10.00%	$1,184.00	18.40%
100.00	0.00%	$1,000.00	0.00%
90.00	-10.00%	$900.00	-10.00%
80.00	-20.00%	$800.00	-20.00%
70.00	-30.00%	$700.00	-30.00%
60.00	-40.00%	$600.00	-40.00%
50.00	-50.00%	$500.00	-50.00%
40.00	-60.00%	$400.00	-60.00%
30.00	-70.00%	$300.00	-70.00%
20.00	-80.00%	$200.00	-80.00%
10.00	-90.00%	$100.00	-90.00%
0.00	-100.00%	$0.00	-100.00%

** Per $1,000 principal amount Note

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 100.00 to a Final Level of 110.00.

Because the Final Level is greater than the Initial Level, the investor receives a payment at maturity of $1,184.00 per $1,000.00 principal amount Note calculated as follows:

$1,000 + [$1,000 × Index Return × Upside Leverage Factor]

$1,000 + [$1,000 × 10.00% × 1.84] = $1,184.00

The total return on investment of the Notes is 18.40%.

Example 3: The level of the Index decreases from an Initial Level of 100.00 to a Final Level of 50.00.

Because Final Level is less than the Initial Level, the investor will receive a payment at maturity of $500.00 per $1,000.00 principal amount Note calculated as follows:

$1,000 + [$1,000 × Index Return]

$1,000 + [$1,000 × -50.00%] = $500.00

The total return on investment of the Notes is -50.00%.

Example 3: The level of the Index increases from an Initial Level of 100.00 to a Final Level of 140.00.

Because the Index Return times the Upside Leverage Factor is greater than the Maximum Return, the investor will receive a payment at maturity of $1,700.12 per $1,000.00 principal amount Note, the maximum possible payment on the Notes.

The total return on investment of the Notes is 70.012%.

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 Index, see “Reference Assets—Indices—Adjustments Relating to Securities with the Reference Asset Comprised of an Index”.

Notwithstanding anything to the contrary in the accompanying prospectus supplement, the Final Valuation Date may be postponed by up to five scheduled trading days due to the occurrence or continuance of a Market Disruption Event on such date. In such a case, the Maturity Date will be postponed such that the number of business days from the Final Valuation Date to the Maturity Date remains the same.

• Exposure to European Equities of the Index—The Index contains the 600 largest stocks by free float market capitalization traded on the major exchanges of 18 European countries. For additional information about the Index, see “Information Regarding the Index” below.

• 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. 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 U.S. 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 derivative 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, your Notes should be treated in the manner described above. This opinion assumes that the description of the terms of the Notes in this preliminary 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 Derivative 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 preliminary pricing supplement.

PPS-6

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 and prospectus addendum, including the risk factors discussed under the following headings of the prospectus supplement (unless otherwise noted):

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

• “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”;

• “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”; and

• “Risk Factors—Under The Terms of the Notes, You Have Agreed To Be Bound By The Exercise of Any U.K. Bail-in Power By The Relevant U.K. Resolution Authority” (in the accompanying prospectus addendum).

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

• Your Investment May Result in a Significant 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. If the Index Return is negative, your Notes will be fully exposed to the decline in the Index from the Initial Level to the Final Level 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.

• Your Maximum Gain on the Notes Is Limited to the Maximum Return—If the Index Return is positive, you will receive a payment at maturity per $1,000 principal amount Note that you hold equal to $1,000 plus an additional amount that will not exceed $1,000 multiplied by the Maximum Return. Accordingly, the maximum payment that you may receive at maturity will be $1,700.12 per $1,000 principal amount Note that you hold. Because the Upside Leverage Factor is 1.84 and because the Maximum Return is 70.012%, you will not benefit from any appreciation of the Index beyond an Index Return of 38.05%, which may be significant.

• 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 the payment 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 May Lose Some or All of Your Investment If Any U.K. Bail-in Power Is Exercised by the Relevant U.K. Resolution Authority—Under the U.K. Banking Act 2009, as recently amended, the relevant U.K. resolution authority may exercise a U.K. Bail-in Power under certain conditions which, in summary, include that such authority determines that: (i) a relevant entity (such as the Issuer) is failing or is likely to fail, (ii) it is not reasonably likely that (ignoring the other stabilization powers under the U.K. Banking Act) any other action will be taken to avoid the entity’s failure, (iii) the exercise of the stabilization powers are necessary taking into account certain public interest considerations such as the stability of the U.K. financial system, public confidence in the U.K. banking system and the protection of depositors and (iv) the objectives of the resolution measures would not be met to the same extent by the winding up of the entity. Notwithstanding these conditions, there remains uncertainty regarding how the relevant U.K. resolution authority would assess these conditions in deciding whether to exercise any Bail-in Power. The U.K. Bail-in Power includes any statutory write-down and conversion power which allows for the cancellation of all, or a portion, of any amounts payable on the Notes, including any repayment of principal and/or the conversion of all, or a portion, of any amounts payable on the Notes, including the repayment of principal, into shares or other securities or other obligations of ours or another person, including by means of a variation to the terms of the Notes. Accordingly, if any U.K. Bail-in Power is exercised you may lose all or a part of the value of your investment in the Notes or receive a different security, which may be worth significantly less than the Notes and which may have significantly fewer protections than those typically afforded to debt securities. Moreover, the relevant U.K. resolution authority may exercise its authority to implement the U.K. Bail-in Power without providing any advance notice to the holders of the Notes.

By your acquisition of the Notes, you acknowledge, agree to be bound by, and consent to the exercise of any U.K. Bail-in Power by the relevant U.K. resolution authority. The exercise of any U.K. Bail-in Power by the relevant U.K. resolution authority with respect to the Notes will not be a default or an Event of Default (as each term is defined in the indenture relating to the Notes) and the trustee will not be liable for any action that the trustee takes, or abstains from taking, in either case, in accordance with the exercise of the U.K. Bail-in Power by the relevant U.K. resolution authority with respect to the Notes. Accordingly, your rights as a holder of the Notes are subject to, and will be varied, if necessary, so as to give effect to, the exercise of any U.K. Bail-in Power by the relevant U.K. resolution authority. Please see “Consent to U.K. Bail-in Power” in this preliminary pricing supplement and the risk factors in the accompanying prospectus addendum for more information.

• Non-U.S. Securities Markets Risks—The component stocks of the Index are issued by foreign companies in foreign securities markets. These stocks may be more volatile and may be subject to different political, market, economic, exchange rate, regulatory and other risks which may have a negative impact on the performance of the financial products linked to the

PPS-7

Index, which may have an adverse effect on the Notes. Also, the public availability of information concerning the issuers of the component stocks of the Index will vary depending on their home jurisdiction and the reporting requirements imposed by their respective regulators. In addition, the issuers of such component stocks may be subject to accounting, auditing and financial reporting standards and requirement that differ from those applicable to United States reporting companies.

• The Notes are Subject to Currency Exchange Rate Risk—The component stocks of the Index are traded and quoted in foreign currencies on non-U.S. markets. Therefore, holders of the Notes will be exposed to currency exchange rate risk with respect to the currencies in which the stocks comprising the Index are denominated. Currency exchange rates 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, foreign governments, central banks or supranational entities, the imposition of currency controls or other national or global political or economic developments. If the applicable currencies appreciate or depreciate relative to the U.S. dollar over the term of the Notes, you will not receive any additional payment or incur any reduction in your payment at maturity. If the value of the currencies in which Index components are denominated strengthens against the U.S. dollar during the term of your Notes, you may not obtain the benefit of that increase, which you would have had you owned directly the securities included in the Index.

• 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 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.

• Historical Performance of the Index Should Not Be Taken as Any Indication of the Future Performance of the Index Over the Term of the Notes—The historical performance of the Index is not an indication of the future performance of the Index over the term of the Notes. Therefore, the performance of the Index over the term of the Notes may bear no relation or resemblance to the historical performance of the Index.

• 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 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 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 might 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 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.

• 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.

• Additional Potential Conflicts—In addition to the variety of roles that we and our affiliates play in connection with the issuance of the Notes described above, we also act as calculation agent and may enter into transactions to hedge our obligations under the Notes. In performing these varied 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.

• 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 require you 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 Index, 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;

• supply and demand for the Notes;

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

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

INFORMATION REGARDING THE INDEX

All information regarding the Index set forth in this preliminary pricing supplement reflects the policies of, and is subject to change by, STOXX Limited (“STOXX”). The Index is calculated, maintained and published by STOXX. The Index is reported by STOXX on Bloomberg page “SXXP” <Index”. It is also disseminated on the STOXX website, www.stoxx.com.

The Index contains the 600 largest stocks by free float market capitalization traded on the major exchanges of 18 European countries. The selection list is composed of each company’s most liquid stock with a minimum liquidity of greater than one million EUR measured over 3-month average daily trading value and is ranked in terms of free-float market capitalization. From the selection list, the largest 550 stocks qualify for selection. The remaining 50 stocks are selected (without regard to liquidity) from the largest remaining current components ranked between 551 and 750. If the number of stocks selected is still below 600, the largest remaining stocks are selected until there are enough stocks.

Publication of the Index was introduced on September 16, 1998 with a base value of 100 as of December 31, 1991.

The composition of the Index is reviewed quarterly, based on the closing stock data on the last trading day of the month following the implementation of the last quarterly index review. The component stocks are announced on the fourth Tuesday of the month immediately prior to the review implementation month. Changes to the component stocks are implemented after the close on the third Friday in each of March, June, September and December and are effective the following trading day.

Corporate actions (including initial public offerings, mergers and takeovers, spin-offs, delistings and bankruptcy) that affect the Index composition are immediately reviewed. Any changes are announced, implemented and effective in line with the type of corporate action and the magnitude of the effect.

The free float factors and weighting cap factors for each component stock used to calculate the STOXX^® Europe 600 Index, as described below, are reviewed, calculated and implemented on a quarterly basis and are fixed until the next quarterly review

The Index is calculated with the “Laspeyres formula,” which measures the aggregate price changes in the component stocks against a fixed base quantity weight. The Index is weighted by free float market capitalization. Each component’s weight is capped at 20% of the Index’s total free float market capitalization. Free float weights and weighting cap factors are reviewed quarterly, as described above.

The Index has an index divisor, which is adjusted to maintain the continuity of the Index’s value across changes due to corporate actions such as the issuance of dividends, the occurrence of stock splits, stock repurchases by the issuer or other reasons.

Additional information regarding the Index is available on the STOXX website at http://www.stoxx.com. Information from outside sources is not incorporated by reference in, and should not be considered a part of, this preliminary pricing supplement.

Historical Performance of the Index

You should not take the historical levels of the Index as an indication of the future performance of the Index.
