Barclays Bank PLC Double Short Leverage Securities

Linked to the Barclays Capital 10Y Treasury Futures Index^™

Investment Description

Double Short Leverage Securities (the “Securities”) are unsecured notes issued by Barclays Bank PLC (the “Issuer”) linked to the performance of the Barclays Capital 10Y Treasury Futures Index^™ (the “Index”). The Securities are designed to replicate a leveraged, double-short position in the Index. Each $1,000.00 principal amount of Securities is being offered for $1,000.00 plus an Upfront Fee. If the Securities have not been redeemed prior to maturity, for each $1,000.00 principal amount of Securities, at maturity, investors will receive a redemption amount equal to (i) the principal amount of $1,000.00 plus a return equal to double the inverse Index Return (which Index Return may be positive, negative or zero), plus (ii) the Additional Amount, minus (iii) the Investor Fee. The Securities will be redeemed prior to maturity if the closing level of the Index on any day during the Observation Period is greater than 140% of the closing level of the Index on the Trade Date. Investors will not receive any periodic interest payments during the term of the Securities. Investing in the Securities involves significant risks. In addition to being subject to the Upfront Fee and the Investor Fee, your return on the Securities will be reduced by any positive performance of the Index on a two-times leveraged basis, and you may lose your entire investment in the Securities. You will have a loss on your investment if the Index Return is positive or not sufficiently negative to offset the effect of the Upfront Fee and the Investor Fee. Any payment on the Securities is subject to the creditworthiness of the Issuer.

Features

q Leveraged Exposure: If you are seeking leveraged exposure to the inverse performance of the Index, the Securities provide double-short exposure to any positive or negative returns of the Index, plus the Additional Amount and less the effect of the Upfront Fee and the Investor Fee.

q Tactical Investment Opportunity: If you have a bearish view of the Index or seek the potential to hedge a portion of your fixed income portfolio, the Securities provide the opportunity to double any negative return of the Index, less the effect of the Upfront Fee and the Investor Fee. However, if the Index increases, after taking into account the Upfront Fee and the Investor Fee, you would experience a loss that is more than double the appreciation of the Index.

Security Offering

FWP-3

Determining Payment at Maturity or Upon Early Redemption

The Redemption Amount, if any, you will receive at maturity or upon early redemption will be calculated based on the closing level of the Index on the Final Valuation Date, the accrued Additional Amount and the applicable Investor Fee. For each $1,000.00 principal amount Security, the Redemption Amount will be calculated as follows:

$1,000.00 × [(1 – (2 × Index Return)] + Additional Amount – Investor Fee

The Redemption Amount cannot be less than $0.00.

In addition to being subject to the Upfront Fee and the Investor Fee, your return on the Securities will be reduced by any positive performance of the Index on a two-times leveraged basis, and you may lose your entire investment in the Securities. You will have a loss on your investment if the Index Return is positive or not sufficiently negative to offset the effect of the Upfront Fee and the Investor Fee.

Optional Early Redemption

You may elect to require Barclays Bank PLC to redeem your Securities, in whole or in part, prior to the maturity date (an “Optional Early Redemption”) on any business day during the Optional Redemption Period (as defined below), subject to a minimum redemption amount of at least 1,000 Securities ($1,000,000 aggregate principal amount). If you elect to have Barclays Bank PLC redeem your Securities, you will receive on the applicable Early Redemption Date a cash payment per Security equal to the Redemption Amount, calculated as of the applicable Final Valuation Date. After your Securities are redeemed pursuant to an Optional Early Redemption, no further amounts will be owed to you under the Securities.

The “Optional Redemption Period” means the period from and including the first business day following the settlement date to and including the business day that is two scheduled trading days prior to the Scheduled Final Valuation Date. You may elect to redeem your Securities only during the Optional Redemption Period.

Redemption Procedures

The following procedures must be followed in order for your Securities to be redeemed pursuant to the Optional Early Redemption:

(1) You must deliver an Optional Early Redemption Request in substantially the form attached hereto as Annex A to your broker or other person through whom you hold your Securities (your “Broker”) using a delivery method acceptable to your Broker. Different brokerage firms may have different deadlines for accepting instructions from their customers. Accordingly, as a beneficial owner of the Securities, you should consult the brokerage firm through which you own your Securities for the relevant deadline;

(2) Your Broker must deliver an Optional Early Redemption Instruction in substantially the form attached hereto as Annex B, to our affiliate via fax and confirm receipt by phone call no later than 12:00 p.m. (New York City time) on any business day during the Optional Redemption Period;

Scenario Analysis and Examples

The following examples illustrate the calculation of the redemption amount for a hypothetical offering of the Securities under various scenarios. Each example below assumes the following terms:

Term	3 years
Issue Price	$1,036.00 per Security
Principal Amount	$1,000.00 per Security
Hypothetical Index Starting Level	183.5368*
Hypothetical Early Redemption Level	256.9515* (140% of the Index Starting Level)

* The actual Index Starting Level and Early Redemption Level will be determined on the Trade Date. The numbers appearing in the following examples have been rounded for ease of analysis.

At Maturity

The following examples assume that no Early Redemption occurs and the Securities are redeemed at maturity. For purposes of these examples, we have assumed that the Additional Amount is $30.00 per $1,000 principal amount Security. The actual Additional Amount will depend upon overnight USD LIBOR during the accrual period, which will fluctuate daily, and upon the actual number of calendar days in the accrual period and may result in a substantially different total Additional Amount.

Example 1 — On the Final Valuation Date, the Index Ending Level is 165.1831, and the Index Return is -10.00%.

Because the Index Return is -10.00%, you will receive a payment at maturity of $1,213.00 per $1,000.00 principal amount Security, calculated as follows:

$1,000.00 × [1 – (Leverage Factor × Index Return)] + Additional Amount – Investor Fee

= $1,000.00 × [1 – (2 × -10.00%)] + $30.00 – (1.70% × $1,000.00)

= $1,000.00 × 1.20 + $30.00 – $17.00

= $1, 213.00

In this example, given an initial investment of $1,036.00, the total return on the Securities is 17.08%.

Example 2 — On the Final Valuation Date, the Index Ending Level is 201.8905, and the Index Return is 10.00%.

Because the Index Return is 10.00%, you will receive a payment at maturity of $813.00 per $1,000.00 principal amount Security, calculated as follows:

$1,000.00 × [1 – (Leverage Factor × Index Return)] + Additional Amount – Investor Fee

= $1,000.00 × [1 – (2 × 10.00%)] + $30.00 – (1.70% × $1,000.00)

= $1,000.00 × 0.80 + $30.00 – $17.00

= $813.00

In this example, given an initial investment of $1,036.00, the total return on the Securities is -21.53%.

Example 3 — On the Final Valuation Date, the Index Ending Level is 183.5368, and the Index Return is 0.00%.

Because the Index Return is 0%, you will receive a payment at maturity of $1,013.00 per $1,000.00 principal amount Security, calculated as follows:

$1,000.00 × [1 – (Leverage Factor × Index Return)] + Additional Amount – Investor Fee

= $1,000.00 × [1 – (2 × 0.00%)] + $30.00 – (1.70% × $1,000.00)

= $1,000.00 × 1 + $30.00 – $17.00

= $1,013.00

In this example, given an initial investment of $1,036.00, the total return on the Securities is -2.22%.

FWP-5

Upon an Early Redemption Event

The following examples assume that the Index closes above the Early Redemption Level during the Observation Period and the Securities are redeemed on the Early Redemption Date. For purposes of these examples, we have assumed that overnight USD LIBOR results in the Additional Amounts as stated. The actual Additional Amount will depend upon overnight USD LIBOR during the accrual period, which will fluctuate daily, and upon the actual number of calendar days in the accrual period and may result in a substantially different total Additional Amount.

Example 1 — The Index closes above 256.9515 and an Early Redemption Event occurs during the second year of the term of the Security. On the Final Valuation Date (the following scheduled trading day), the Index Ending Level is 230.0000, and the Index Return is 25.32%. For purposes of this example, we have assumed that the Additional Amount is $2.00 per $1,000 principal amount Security.

Because the Index Return is 25.32%, you will receive a payment on the Early Redemption Date of $487.19 per $1,000.00 principal amount Security, calculated as follows:

$1,000.00 × [1 – (Leverage Factor × Index Return)] + Additional Amount – Investor Fee

= $1,000.00 × [1 – (2 × 25.32%)] + $2.00 – (0.85% × $1,000.00)

= $1,000.00 × 0.4937 + $2.00 – $8.50

= $487.19

In this example, given an initial investment of $1,036.00, the total return on the Securities is -52.97%.

Example 2 — The Index closes above 256.9515 and an Early Redemption Event occurs during the third year of the term of the Security. On the Final Valuation Date (the following scheduled trading day), the Index Ending Level is 285.0000, and the Index Return is 55.28%. For purposes of this example, we have assumed that the Additional Amount is $18.00 per $1,000 principal amount Security.

Because the Index Return is 55.28%, you will receive no payment on the early redemption date, calculated as follows:

$1,000.00 × [1 – (Leverage Factor × Index Return)] + Additional Amount – Investor Fee

= $1,000.00 × [1 – (2 × 55.28%)] + $18.00 – (1.70% × $1,000.00)

= $1,000.00 × -0.1056 + $18.00 – $17.00

= -$104.64

Because the Redemption Amount cannot be negative, the payment on the Early Redemption Date will be $0.00 per Security, and investors will suffer a total loss of their investment in the Securities. In this example, given an initial investment of $1,036.00, the total return on the Securities is -100%.

FWP-6

Hypothetical Return Tables

The following table illustrates the Redemption Amount and total return on the Securities. The “total return” as used in this free writing prospectus is the number, expressed as a percentage, that results from comparing the payment at maturity per $1,000.00 principal amount Security to the issue price of $1,036.00. 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 Securities. The numbers appearing in the following table and examples have been rounded for ease of analysis.

Term	3 years
Issue Price	$1,036.00 per Security
Principal Amount	$1,000.00 per Security
Hypothetical Index Starting Level	183.5368*
Hypothetical Early Redemption Level	256.9515* (140% of the Index Starting Level)
Additional Amount	$30.00 per Security**
Investor Fee:	$17.00 per Security***

* The actual Index Starting Level and Early Redemption Level will be determined on the Trade Date.

** The actual Additional Amount will depend upon overnight USD LIBOR during the accrual period, which will fluctuate daily, and upon the actual number of calendar days in the accrual period and may result in a substantially different total Additional Amount. For purposes of these examples, we have assumed that the Additional Amount is $30.00 per $1,000 principal amount Security. If the Securities are redeemed early, the Additional Amount may be substantially less than $30.00.

*** If the Securities are redeemed early and the Final Valuation Date occurs on or prior to the day occurring 2 years following the Settlement Date, the Investor Fee will be less than $17.00.

* Return figures depicted above are not annualized. Annualized return figures would express a greater percentage loss on an investment in the Securities if they are redeemed early. Additionally, because the Securities offer short exposure to the Index, the potential return of the Securities will be limited by the fact that the Index Return can never be less than -100%.

What are the tax consequences of the Securities?

Some of the tax consequences of your investment in the Securities 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 Securities as capital assets for tax purposes and does not apply to you if you are a member of a class of holders subject to special rules or are otherwise excluded from the discussion in the prospectus supplement.

The United States federal income tax consequences of your investment in the Securities are uncertain and the Internal Revenue Service could assert that the Securities should be taxed in a manner that is different than described below. Pursuant to the terms of the Securities, 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 Securities as a pre-paid cash-settled executory contract with respect to the Index. If your Securities are so treated, you should generally recognize capital gain or loss upon the sale, redemption or maturity of your Securities in an amount equal to the difference between the amount you receive at such time and the amount you paid for your Securities (including the Upfront Fee). Such gain or loss should generally be long-term capital gain or loss if you have held your Securities for more than one year.

In the opinion of our special tax counsel, Sullivan & Cromwell LLP, it would be reasonable to treat your Securities in the manner described above. This opinion assumes that the description of the terms of the Securities in this free writing prospectus is materially correct.

As discussed further in the accompanying prospectus supplement, the Treasury Department and the Internal Revenue Service are actively considering various alternative treatments that may apply to instruments such as the Securities, possibly with retroactive effect. Other alternative treatments for your Securities may also be possible under current law. For example, it is possible that the Internal Revenue Service could assert that Section 1256 of the Internal Revenue Code should apply to your Securities or a portion of your Securities. If Section 1256 were to apply to your Securities, gain or loss recognized with respect to your Securities (or the relevant portion of your Securities) would be treated as 60% long-term capital gain or loss and 40% short-term capital gain or loss, without regard to your holding period in the Securities. You would also be required to mark your Securities (or a portion of your Securities) to market at the end of each year (i.e., recognize gain or loss as if the Securities or the relevant portion of the Securities had been sold for fair market value). It is also possible that you could be required to recognize gain or loss each time a contract tracked by the Index rolls. Moreover, it is possible that you would be required to include the Additional Amount in ordinary income either upon the sale, redemption or maturity of the Securities or over the term of your Securities even though you will not receive any payments from us until the redemption or maturity of your Securities. Additionally, it is possible that the Internal Revenue Service could assert that your holding period in respect of your Securities should end on the date on which the amount you are entitled to receive upon redemption or maturity of your securities is determined, even though you will not receive any amounts in respect of your Securities prior to the redemption or maturity of the Securities. In such case, there are circumstances under which you may be treated as having a holding period in respect of your Securities that is less than one year even if you receive cash upon the early redemption of your Securities at a time that is more than one year after the beginning of your holding period. It is also possible that you may be required to treat an amount equal to all or a portion of the Upfront Fee and amounts attributable to the Investor Fee as expenses. The deduction of any such deemed expenses would generally be subject to the 2% floor on miscellaneous itemized deductions. Such amounts would correspondingly increase the amount of gain or decrease the amount of loss that you recognize with respect to your Securities. There may also be a risk that the Internal Revenue Service could assert that the Securities should not give rise to long-term capital gain or loss because the Securities offer exposure to a short investment strategy.

For a further discussion of the tax treatment of your Securities as well as other 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 Securities. For additional, important considerations related to tax risks associated with investing in the Securities, you should also examine the discussion in “Key Risks — Taxes”, in this free writing prospectus.

Recently Enacted Legislation. Under recently enacted legislation, individuals that own “specified foreign financial assets” with an aggregate value in excess of $50,000 in taxable years beginning after March 18, 2010 will generally be 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 Securities), 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. Individuals are urged to consult their tax advisors regarding the application of this legislation to their ownership of the Securities.

Key Risks

An investment in the Securities involves significant risks. Investing in the Securities is not equivalent to investing directly in the Index. Some of the risks that apply to an investment in the Securities offered hereby are summarized below, but we urge you to read the more detailed explanation of risks relating to the Securities generally in the “Risk Factors” section of the prospectus supplement. You should reach an investment decision only after you have carefully considered with your advisors the suitability of an investment in the Securities in light of your particular circumstances.

^¨ No Principal Protection and Leveraged Downside Exposure — You may lose some or all of your initial investment. The Securities do not guarantee any return of principal. The return on the Securities 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. For every 1% increase in the Index Return, you will lose 2% of your initial investment at maturity, subject to the Upfront Fee, the Investor Fee and the Additional Amount. You may lose all or a substantial portion of your initial investment.

^¨ Reinvestment Risk — If the Securities are redeemed prior to maturity pursuant to an Optional Early Redemption or Early Redemption Event, you will receive on the Early Redemption Date a cash payment per Security equal to the Redemption Amount. The Additional Amount will cease to accrue and you will not be entitled to any further payments after the Early Redemption Date, including any payment at maturity, even if the level of the Index declines subsequent to the Optional Early Redemption or Early Redemption Event. If the Securities are redeemed early, there is no guarantee that you would be able to reinvest the proceeds from an investment in the Securities, if any, in a comparable investment with similar characteristics as the Securities.

^¨ The Level of the Index Prior to the Final Valuation Date Is Not Relevant in Calculating the Index Return — The Index Return used to calculate the Redemption Amount depends on the closing level of the Index on the Final Valuation Date. If the level of the Index on the Final Valuation Date is not sufficiently below the Index Starting Level, you will lose some or all of your principal even if the level of the Index at any time prior to the Final Valuation Date would have been sufficiently below the Index Starting Level to provide you with a positive return on your investment in the Securities.

In addition, upon an Early Redemption Event, the Index Ending Level will be measured on the following scheduled trading day; therefore, the Index Ending Level could be higher than the closing level of the Index on the day of the Early Redemption Event. Alternatively, the Index Ending Level following an Early Redemption Event could be lower than the Early Redemption Level, however the Securities will still be redeemed without requiring your consent.

^¨ The Securities are Subject to an Early Redemption Feature That May Automatically Terminate Your Leveraged Exposure to the Index — The Securities will be redeemed early, without your consent, if on any day during the Observation Period the closing level of the Index is greater than the Early Redemption Level. Following an Early Redemption Event, you will receive a redemption amount that will likely be significantly less than your initial investment in the Securities and could be zero. If your Securities are subject to an early redemption, the Additional Amount will cease to accrue and you will not be entitled to any further payments, including any payment at maturity, after the Early Redemption Date even if the level of the Index declines substantially subsequent to the Early Redemption Event.

^¨ Your Optional Redemption Election is Irrevocable — You will not be able to rescind your election to redeem your Securities after we receive your redemption notice. Accordingly, you will be exposed to market risk in the event market conditions change after we receive your offer and before the Redemption Amount is determined on the applicable Final Valuation Date.

^¨ You Will Not Receive Periodic Interest Payments on the Securities or Have Rights in the 10Y Treasury Futures — You will not receive any periodic interest payments on the Securities other than the Additional Amount paid at maturity or upon early redemption. As an owner of the Securities, you will not have rights that investors in 10Y Treasury futures may have.

^¨ Limited Liquidity — The Securities will not be listed on any securities exchange. As discussed above, you may elect to redeem your Securities, but your right to redemption is subject the conditions and procedures described in this free writing prospectus including the requirement that you redeem at least 1,000 Securities at one time. Barclays Capital Inc. and other affiliates of Barclays Bank PLC intend to offer to purchase the Securities in the secondary market but are not required to do so and may cease any such market making activities at any time. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the Securities easily. Because other dealers are not likely to make a secondary market for the Securities, the price at which you may be able to trade your Securities 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 Securities.

^¨ Certain Built in Costs are Likely to Adversely Affect the Value of the Securities Prior to Maturity and the Payment You Receive at Maturity — The original issue price of the Securities as set forth on the cover of this free writing prospectus includes the agents’ commission and the estimated costs of hedging our obligations under the Securities through one or more of our affiliates and managing the Index. As a result, assuming no change in market conditions or any other relevant factors, the price, if any, at which Barclays Bank PLC or any of its affiliates will be willing to purchase the Securities from you prior to maturity in secondary market transactions, if at all, will likely be lower than the original issue price, and any such sale prior to the maturity date could result in a substantial loss to you. Moreover, this hedging activity may result in Barclays Bank PLC or its affiliates realizing a profit, even if the market value of the Securities decline. The Securities are not designed to be short-term trading instruments. Accordingly, you should be willing and able to hold your Securities to maturity. In addition, due to these costs, you are paying an original issue price in excess of the principal amount of each Security, while your payment at maturity will be calculated based on a lesser amount, namely the principal amount of $1,000.00 per Security. Therefore, the Upfront Fee will not grow along with any depreciation in the Index. If the Index Return is negative, but the decline in the Index is insufficient to offset the effect of the Upfront Fee and the Investor Fee (after taking into account the Additional Amount), you will have a loss on your investment in the Securities.

FWP-9

^¨ Even If the Index Depreciates Over the Term of the Securities, You May Receive Less Than Your Initial Investment — Because the Upfront Fee and the Investor Fee reduce the amount of your return at maturity or upon redemption, the level of the Index must decrease sufficiently to offset these fees for you to receive at least the amount of your initial investment at maturity or upon redemption. If the Index Ending Level has not decreased from the Index Starting Level by an amount sufficient to offset the amount of the Upfront Fee and the Investor Fee, or if the Index Ending Level is equal to or greater than the Index Starting Level, you will receive less than your original investment at maturity or upon early redemption.

^¨ The Potential Returns from Short Exposure to the Index is Limited — Because the Securities offer short exposure to the Index, the potential return of the Securities will be limited by the fact that the Index Return can never be less than -100%.

^¨ Dealer Incentives — We, our affiliates and agents act in various capacities with respect to the Securities. We and our affiliates may act as a principal, agent or dealer in connection with the Securities. Such affiliates, including the sales representatives, will derive compensation from the distribution of the Securities and such compensation may serve as an incentive to sell these Securities instead of other investments. We will pay compensation to the principals, agents and dealers in connection with the distribution of the Securities as set forth on the cover of this free writing prospectus.

^¨ Credit of the Issuer — The Securities are 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 Securities depends on the ability of Barclays Bank PLC to satisfy its obligations as they come due. As a result, the actual and perceived creditworthiness of Barclays Bank PLC may affect the market value of the Securities and, in the event Barclays Bank PLC were to default on its obligations, you may not receive the principal protection or any other amounts owed to you under the terms of the Securities.

^¨ Potentially Inconsistent Research, Opinions or Recommendations by Barclays Capital Inc., UBS Financial Services Inc. or Their Respective Affiliates — Barclays Capital Inc., UBS Financial Services Inc. or their respective affiliates and agents may publish research from time to time on financial markets and other matters that may influence the value of the Securities, or express opinions or provide recommendations that are inconsistent with purchasing or holding the Securities. Any research, opinions or recommendations expressed by Barclays Capital Inc., UBS Financial Services Inc. or their respective affiliates or agents may not be consistent with each other and may be modified from time to time without notice. You should make your own independent investigation of the merits of investing in the Securities and the underlying equity to which the Securities are linked.

^¨ Taxes — The U.S. federal income tax treatment of the Securities is uncertain and the Internal Revenue Service could assert that the Securities 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 Securities even though you will not receive any payments with respect to the Securities until redemption or maturity and whether all or part of the gain you may recognize upon the sale, redemption or maturity of an instrument such as the Securities 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 Securities.

^¨ Many Economic and Market Factors Will Affect the Value of the Securities — In addition to the level of the Index on any day, the value of the Securities will be affected by a number of economic and market factors that may either offset or magnify each other, including:

• the time to maturity of the Securities;

• the prevailing interest rate environment;

• economic, financial, political, regulatory, geographical or judicial events that affect interest rates;

• supply and demand for the Securities; and

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

These factors interrelate in complex ways, and the effect of one factor on the market value of your Securities may offset or enhance the effect of another factor.

^¨ The Closing Price of the Relevant 10Y Treasury Futures Contract May Not Be Readily Available — As described in the section entitled “The Barclays Capital 10Y Treasury Futures Index™” in this free writing prospectus, the closing price of the relevant 10Y Treasury futures contract is calculated and published by the Chicago Board of Trade (CBOT). The closing price of the relevant 10Y Treasury futures contract is used to calculate the level of the Index. Any disruption in CBOT trading of the relevant 10Y Treasury futures contract could delay the release or availability of the closing price. This may delay or prevent the calculation of the Index.

^¨ Historical Levels of the Index Should Not Be Taken as an Indication of the Future Performance of the Index During the Term of the Securities — It is impossible to predict whether the Index will rise or fall. The actual performance of the Index over the term of the Securities, as well as the amount payable at maturity may bear little relation to the historical level of the Index.

^¨ As Index Sponsor, Barclays Capital, a Division of Barclays Bank PLC, Will Have the Authority To Make Determinations That Could Materially Affect Your Securities in Various Ways and Create Conflicts of Interest — Barclays Capital, a division of Barclays Bank PLC, is the index sponsor. The index sponsor is responsible for the composition, calculation and maintenance of the Index. As discussed in the section entitled “The Barclays Capital 10Y Treasury Futures Index™” in this free writing prospectus, the index sponsor has the discretion in a number of circumstances to make judgments and take actions in connection with the composition, calculation and maintenance of the Index, and any such judgments or actions may adversely affect the value of the Securities.

FWP-10

The role played by Barclays Capital, as index sponsor and the exercise of the kinds of discretion described above and in the section entitled “The Barclays Capital 10Y Treasury Futures Index™” in this free writing prospectus could present it with significant conflicts of interest in light of the fact that Barclays Bank PLC, of which Barclays Capital is a division, is the issuer of the Securities. The index sponsor has no obligation to take the needs of any buyer, seller or holder of the Securities into consideration at any time.

^¨ There Are Potential Conflicts of Interest between You and the Calculation Agent — Barclays Bank PLC will serve as the calculation agent. The calculation agent will, among other things, decide the amount of the return paid out to you on the Securities at maturity or upon early redemption. If the index sponsor were to discontinue or suspend calculation or publication of the Index, it may become difficult to determine the market value of the Securities. If events such as these occur, or if the value of the Index is not available or cannot be calculated for any reason, the calculation agent may be required to make a good faith estimate in its sole discretion of the value of the Index or to postpone the Final Valuation Date or the maturity date.

^¨ Trading and Other Transactions by Barclays Bank PLC or its Affiliates in 10Y Treasury Futures or Related Interest Rate Futures or Related Instruments May Impair the Market Value of the Securities — We or one or more of our affiliates may hedge our obligations under the Securities by purchasing futures or options on interest rates or the Index, or other derivative instruments with returns linked to interest rates or the Index, and we may adjust these hedges by, among other things, purchasing or selling any of the foregoing. Any of these hedging activities may affect prevailing prices for the 10Y Treasury futures and the level of the Index and, therefore, the market value of the Securities. It is possible that we or one or more of our affiliates could receive substantial returns from these hedging activities while the market value of the Securities declines.

We or one or more of our affiliates may also engage in trading in futures or options on interest rates or the Index, or other derivative instruments with returns linked to interest rates or the Index on a regular basis as part of our general broker-dealer and other businesses, for proprietary accounts, for other accounts under management or to facilitate transactions for customers. Any of these activities may affect prevailing prices for the 10Y Treasury futures and the level of the Index and, therefore, the market value of the Securities. We or one or more of our affiliates may also issue or underwrite other securities or financial or derivative instruments with returns linked or related to changes in the performance of any of the foregoing. By introducing competing products into the marketplace in this manner, we or one or more of our affiliates could adversely affect the market value of the Securities. With respect to any of the activities described above, neither Barclays Bank PLC nor any of its affiliates has any obligation to take the needs of any buyer, seller or holder of the Securities into consideration at any time.

^¨ Our Business Activities May Create Conflicts of Interest — In addition to the role of Barclays Capital, a division of Barclays Bank PLC, as index sponsor as described under “As Index Sponsor, Barclays Capital, a Division of Barclays Bank PLC, Will Have the Authority To Make Determinations That Could Materially Affect Your Securities in Various Ways and Create Conflicts of Interest”, we and our affiliates expect to play a variety of roles in connection with the issuance of the Securities.

As noted above, we and our affiliates expect to engage in trading activities related to futures or options on interest rates or the Index, or other derivative instruments with returns linked to futures, interest rates or the Index that are not for the accounts of holders of the Securities or on their behalf. These trading activities may present a conflict between the holders’ interest in the Securities and the interests that we and our affiliates will have in our and our affiliates’ proprietary accounts, in facilitating transactions, including options and other derivatives transactions, for our and our affiliates’ customers and in accounts under our and our affiliates’ management. These trading activities, if they influence the value of the Index, could be adverse to the interests of the holders of the Securities.

Moreover, we and our affiliates have published and in the future expect to publish research reports with respect to 10Y Treasury futures and interest rates. This research is modified from time to time without notice and may express opinions or provide recommendations that are inconsistent with purchasing or holding the Securities. The research should not be viewed as a recommendation or endorsement of the Securities in any way and investors must make their own independent investigation of the merits of this investment. Any of these activities by us, Barclays Capital Inc. or our other affiliates may affect prevailing prices of 10Y Treasury futures and the level of the Index and, therefore, the market value of the Securities. With respect to any of the activities described above, neither Barclays Bank PLC nor any of its affiliates has any obligation to take the needs of any buyer, seller or holder of the Securities into consideration at any time.

^¨ The Policies of the Index Sponsor and Changes That Affect the Composition and Valuation of the Index Could Affect the Amount Payable on the Securities and Their Market Value — The policies of the index sponsor, which is a division of Barclays Bank PLC, concerning the calculation of the level of the Index could affect the value of the Index and, therefore, the amount payable on the Securities at maturity and the market value of the Securities prior to maturity.

The index sponsor may modify the methodology for calculating the value of the Index. In addition, as described in “The Barclays Capital 10Y Treasury Futures Index™ — Modifications to the Index” in this free writing prospectus, under a number of circumstances the index sponsor may make certain changes to the way in which the Index is calculated. The index sponsor may also discontinue or suspend calculation or publication of the Index, in which case it may become difficult to determine the market value of the Index. Any such changes could adversely affect the value of your Securities.

If events such as these occur, or if the value of the Index is not available or cannot be calculated for any reason, the calculation agent may be required to make a good faith estimate in its sole discretion of the value of the Index. The circumstances in which the calculation agent will be required to make such a determination are described more fully under “Reference Assets — Indices — Market Disruption Events for Securities with the Reference Asset Comprised of an Index or Indices of Equity Securities, Interest Rates, Currency Exchange Rates, Currencies, or Other Assets or Variables (Other than Commodities)” and “Reference Assets — Indices — Adjustments Relating to Securities with the Reference Asset Comprised of an Index or Indices.”

The Barclays Capital 10Y Treasury Futures Index™

The Barclays Capital 10Y Treasury Futures Index™ (the “Index”) reflects the returns available by maintaining a rolling position in 10-Year U.S. Treasury futures contracts (the “10Y Treasury futures” and each, a “10Y Treasury futures contract”). 10Y Treasury futures are legally binding agreements for the buying or selling of U.S. Treasury notes at a fixed price for physical settlement on a future date. Each 10Y Treasury futures contract has a face value of $100,000 and requires the delivery of a U.S. Treasury note with a remaining maturity or term of no more than 10 years and no less than 6 years and 6 months. 10Y Treasury futures are traded on the Chicago Board of Trade (“CBOT”). The closing prices of 10Y Treasury futures are calculated by CBOT and reported on Bloomberg under symbol “TY”. As used herein, an “index business day” means any day that CBOT is scheduled to be open for trading.

At any given time, the Index is comprised of a single 10Y Treasury futures contract that is either the contract closest to expiration, which is known as the “front 10Y Treasury futures contract”, or the next 10Y Treasury futures contract scheduled to expire immediately following the front 10Y Treasury futures contract. The Index maintains its exposure to 10Y Treasury futures by closing out its position in the expiring front 10Y Treasury futures contract and establishing a new position in the next 10Y Treasury futures contract scheduled to expire immediately following the front 10Y Treasury futures contract, a process referred to as “rolling.” The Index rolls into the next 10Y Treasury futures contract three index business days before the end of the month immediately preceding the upcoming delivery month for the front 10Y futures contract (each such date, a “roll date”). The “delivery months” of 10Y Treasury futures are March, June, September and December, and their corresponding roll dates fall in the months of February, May, August and November.

The Index is maintained and calculated by Barclays Capital (the “index sponsor”), a division of Barclays Bank PLC, and is denominated in U.S. dollars. The index sponsor calculates the level of the Index at the close of business, London time, on each index business day with respect to the prior index business day and publishes it on http://www.barcap.com/indices shortly thereafter. The level of the Index is also reported on Bloomberg page BXIIUS10.

The information on the Index provided in this free writing prospectus should be read together with the discussion under the heading “Proprietary Indices — Barclays Capital 10Y Treasury Futures Index™” in the index supplement.

Historical Performance of the Index

The level of the Index is deemed to have been 100 on January 15, 1997, which is referred to as the “index commencement date”. The index sponsor began calculating the Index on January 15, 2009. Therefore, the historical information for the period from January 15, 1997 until January 15, 2009, is hypothetical and is provided as an illustration of how the Index would have performed during the period had the index sponsor begun calculating the Index on the index commencement date using the methodology it currently uses. This data does not reflect actual performance, nor was a contemporaneous investment model run of the Index. Historical information for the period from and after January 15, 2009 is based on the actual performance of the Index.

All calculations of historical information are based on information obtained from various third party independent and public sources. The index sponsor has not independently verified the information extracted from these sources.

The following table illustrates the annual performance of the Index from the index commencement date to August 30, 2010. The estimated historical performance of the Index should not be taken as an indication of future performance, and no assurance can be given that the value of the Index will decrease sufficiently to cause holders of the Securities to receive a payment at maturity in excess of the principal amount of such Securities.

Date	Level of the Index	Date	Level of the Index

FWP-12

The following graph sets forth the historical performance of the Barclays Capital 10Y Treasury Futures Index™ based on the monthly closing levels of the Barclays Capital 10Y Treasury Futures Index™ as well as the historical performance of the yield of the 10 year on-the-run U.S. Treasury note from January 31, 1997 through July 30, 2010. As used herein, “on-the-run” refers to the most recently issued U.S. Treasury note of the specified tenor. The correlation between the monthly returns of the Barclays Capital 10Y Treasury Futures Index™ and the monthly changes in the yield of the 10 year on-the-run U.S. Treasury note is -0.97.

We obtained the closing levels of the Barclays Capital 10Y Treasury Futures Index™ and yields on the 10 year on-the-run Treasury note below from Bloomberg, L.P. (Bloomberg tickers: BXIIUS10 Index and GT10 Govt, respectively). We make no representation or warranty as to the accuracy or completeness of the information obtained from Bloomberg, L.P. The historical levels should not be taken as an indication of future performance or correlation, and no assurance can be given as to the closing level of the Index on any day during the observation period or on the Final Valuation Date. We cannot give you assurance that the performance of the Barclays Capital 10Y Treasury Futures Index™ will result in the return of any of your initial investment.
