Initial Valuation Date:	April 1, 2008
Issue Date:	April 4, 2008
Final Valuation Date:	May 4, 2009*

Maximum Return:	The actual maximum return on the Notes will be set on the initial valuation date and will not be less than 21.52%.
Payment at Maturity:	If the final level is greater than the initial level, you will receive a cash payment that provides you with a return per $1,000 principal amount Note equal to the index return multiplied by four, subject to a maximum return on the Notes of 21.52%. For example, if the index return is 5.38% or more, you will receive the maximum return on the Note of 21.52%, which entitles you to the maximum payment of $1,215.20 for every $1,000 principal amount Note that you hold.

If the final level declines from the initial level, you will lose 1% of the principal amount of your Notes for every 1% that the Index declines beyond the initial index level. Accordingly, if the index return is negative, your payment per $1,000 principal amount Note will be calculated as follows: $1,000 + ($1,000 x Index Return) You will lose some or all of your investment at maturity if the final level declines from the initial level.

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 free writing prospectus 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 assume an initial level of 1,325.76 and a maximum return on the Notes of 21.52%. 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.

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 1,325.76 to a final level of 1,392.05.

Because the final level of 1,329.05 is greater than the initial level of 1,325.76 and the index return of 5.00% multiplied by four does not exceed the hypothetical maximum return of 21.52%, the investor receives a payment at maturity of $1,200.00 per $1,000 principal amount Note calculated as follows:

$1,000 + [$1,000 x (5.00% x 4)] = $1,200.00

Example 2: The level of the Index decreases from an initial level of 1,325.76 to a final level of 1,193.18.

Because the final level of 1,193.18 is less than the initial level of 1,325.76, the index return is negative and the investor will receive a payment at maturity of $900 per $1,000 principal amount Note.

$1,000 + ($1,000 x -10%) = $900

Example 3: The level of the Index increases from an initial level of 1,325.76 to a final level of 1,590.91.

Because the index return of 20% multiplied by four exceeds the hypothetical maximum return of 21.52%, the investor receives a payment at maturity of $1,215.20 per $1,000 principal amount Note, the maximum payment on the Notes.

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

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

• Appreciation Potential—The Notes provide the opportunity to enhance equity returns by multiplying a positive index return by four, up to the maximum return on the Notes of 21.52%, or $1,215.20 for every $1,000 principal amount Note. The actual maximum return on the Notes will be set on the initial valuation date and will not be less than 21.52%. Because the Notes are our senior unsecured obligations, payment of any amount at maturity is subject to our ability to pay our obligations as they become due.

• Diversification Among U.S. Equities of the S&P 500^® Index—The return on the Notes is linked to the S&P 500^® Index. The S&P 500^® Index consists of 500 component stocks selected to provide a performance benchmark for the U.S. equity markets. For additional information about the Index, see the information set forth under “Description of the Reference Asset” in this free writing prospectus.

• Certain U.S. Federal Income Tax Considerations—The United States federal income tax consequences of your investment in the Notes are uncertain. Pursuant to the terms of the Notes, Barclays Bank PLC and you agree, in the absence of a change

FWP–3

in law or an administrative or judicial ruling to the contrary, to characterize your Notes as a pre-paid cash-settled executory contract with respect to the Index. If your Notes are so treated, you should generally recognize capital gain or loss upon the sale or maturity of your Notes in an amount equal to the difference between the amount you receive at such time and the amount you paid for your Notes. Such gain or loss would generally be long-term capital gain or loss if you have held your Notes for more than one year.

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

As discussed further in the accompanying information 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. In addition, legislation has recently been introduced in Congress that, if enacted, would require holders that acquire the Notes after the bill is enacted to accrue interest income over the term of the Notes despite the fact that there will be no interest payments over the term of the Notes. It is not possible to predict whether this bill or a similar bill will be enacted in the future and whether any such bill would affect the tax treatment of your Notes.

For a further discussion of the tax treatment of your Notes as well as possible alternative characterizations, please see the discussion under the heading “Certain U.S. Federal Income Tax Considerations—Certain Notes Treated as Forward Contracts or Executory Contracts” in the accompanying prospectus supplement and the discussion under the heading “United States Federal Tax Considerations” in the accompanying information supplement. 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 free writing prospectus. You should further consult your tax advisor as to the possible alternative treatments in respect of the Notes.

Selected Risk Considerations

An investment in the Notes involves significant risks. Investing in the Notes is not equivalent to investing directly in the basket components. These risks are explained in more detail in the “Risk Factors” section of the prospectus supplement, including the risk factors discussed under the following headings:

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

• “Risk Factors—Additional Risks Relating to Notes Which Pay No Interest”; and

• “Risk Factors—Additional Risks Relating to Notes with Reference Assets That Are Equity Securities, That Contain Equity Securities or That Are Based in Part on Equity Securities”.

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

• Your Investment in the Notes May Result in a Loss—The Notes do not guarantee any return of principal. The return on the Notes at maturity is linked to the performance of the Index and will depend on whether, and the extent to which, the index return is positive or negative. Your investment will be fully exposed to any decline in the final level as compared to the initial level.

• Your Maximum Gain on the Notes Is Limited to the Maximum Return—If the final level is greater than the initial level, for each $1,000 principal amount Note, you will receive at maturity $1,000 plus an additional amount that will not exceed a predetermined percentage of the principal amount, regardless of the appreciation in the Index, which may be significant. We refer to this percentage as the maximum return, which will be set on the initial valuation date and will not be less than 21.52%.

• 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.

• Certain Built-In Costs Are Likely to Adversely Affect the Value of the Notes Prior to Maturity—While the payment at maturity described in this free writing prospectus is based on the full principal amount of your Notes, the original issue price of the Notes includes the agent’s commission and the cost of hedging our obligations under the Notes through one or more of our affiliates. As a result, the price, if any, at which Barclays Capital Inc. and other affiliates of Barclays Bank PLC will be willing to purchase Notes from you in secondary market transactions will likely be lower than the original issue price, and any sale prior to the maturity date could result in a substantial loss to you. The Notes are not designed to be short-term trading instruments. Accordingly, you should be able and willing to hold your Notes to maturity.

• Lack of Liquidity—The Notes will not be listed on any securities exchange. Barclays Capital Inc. and other affiliates of Barclays Bank PLC intend to offer to purchase the Notes in the secondary market but are not required to do so. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the Notes easily. Because other dealers are not likely to make a secondary market for the Notes, the price at which you may be able to trade your Notes is likely to depend on the price, if any, at which Barclays Capital Inc. and other affiliates of Barclays Bank PLC are willing to buy the Notes.

FWP–4

• Potential Conflicts—We and our affiliates play a variety of roles in connection with the issuance of the Notes, including acting as calculation agent and hedging our obligations under the Notes. In performing these duties, the economic interests of the calculation agent and other affiliates of ours are potentially adverse to your interests as an investor in the Notes.

• Taxes—The 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 information supplement, on December 7, 2007, the Internal Revenue Service issued a notice indicating that it and the Treasury Department are actively considering whether, among other issues, you should be required to accrue interest over the term of an instrument such as the Notes even though you will not receive any payments with respect to the Notes until maturity and whether all or part of the gain you may recognize upon sale or maturity of an instrument such as the Notes could be treated as ordinary income. The outcome of this process is uncertain and could apply on a retroactive basis. In addition, legislation has recently been introduced in Congress that, if enacted, would require holders that acquire the Notes after the bill is enacted to accrue interest income over the term of the Notes despite the fact that there will be no interest payments over the term of the Notes. It is not possible to predict whether this bill or a similar bill will be enacted in the future and whether any such bill would affect the tax treatment of your Notes. You should consult your tax advisor as to the possible alternative treatments in respect of the Notes.

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

• the expected volatility of the Index;

• the time to maturity of the Notes;

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

• interest and yield rates in the market generally;

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

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