SELECTED RISK FACTORS

An investment in the Notes involves significant risks not associated with an investment in conventional floating rate or fixed rate medium term notes. You should read the risks summarized below in connection with, and the risks summarized below are qualified by reference to, the risks described in more detail in the “Risk Factors” section beginning on page S-5 of the prospectus supplement. We urge you to consult your investment, legal, tax, accounting and other advisers and to invest in the Notes only after you and your advisors have carefully considered the suitability of an investment in the Notes in light of your particular circumstances.

• Reference Rate / Interest Payment Risk—The amount of interest payable on the Notes (after the initial Interest Periods for which the Initial Interest Rate is payable) is linked to the CPI Performance, which for each Interest Payment Date is equal to the annual percentage change in the CPI (as calculated by the Bureau of Labor Statistics) for the period up to and including the stated calendar month prior to the month of the relevant Interest Payment Date (the “Reference Month”), as described in the prospectus supplement. For example, as the Reference Month is specified as the third calendar month prior to the month of the relevant Interest Payment Date, for an Interest Payment Date in June of any year, the Reference Month would be March, and the amount of interest paid on the Interest Payment Date in June would be calculated using a CPI Performance that reflects the annual percentage change in the CPI from the March of the prior year to March of the year in which the Interest Payment Date occurs. Because the variable rate paid on the Notes is linked to the CPI Performance, if the CPI decreases, does not increase, or increases only minimally, the amount of interest for any Interest Payment Date may be lower than for any prior Interest Payment Date and could be no more than the specified Minimum Interest Rate of 1.00%; as a result, the effective interest rate on the Notes and the value of the Notes may be less than the rate on debt securities with the same maturity issued by us or an issuer with a comparable security rating. In addition, you are assuming the risk that the Bureau of Labor Statistics may change the way in which the CPI is calculated, which changes may impact the CPI Performance used to calculate interest for the Notes and could result in lower or no interest payments.

• Issuer Credit Risk—The Notes are our unsecured debt obligations, and are not, either directly or indirectly, an obligation of any third party. Any payment to be made on the Notes, including any principal protection provided at maturity, depends on our ability to satisfy our obligations as they come due. As a result, the actual and perceived creditworthiness of Barclays Bank PLC may affect the market value of the Notes and, in the event we were to default on our obligations, you may not receive the principal protection or any other amounts owed to you under the terms of the Notes.

• Certain Built-In Costs Are Likely to Adversely Affect the Value of the Notes Prior to Maturity—Although you will not receive less than the principal amount of the Notes if you hold the Notes to maturity (subject to Issuer credit risk), 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, assuming no change in market conditions or any other relevant factor, 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.

• 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. 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.

• 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.

PS–1

In addition, Barclays Wealth, the wealth management division of Barclays Capital Inc., may arrange for the sale of the Notes to certain of its clients. In doing so, Barclays Wealth will be acting as agent for Barclays Bank PLC and may receive compensation from Barclays Bank PLC in the form of discounts and commissions. The role of Barclays Wealth as a provider of certain services to such customers and as agent for Barclays Bank PLC in connection with the distribution of the Notes to investors may create a potential conflict of interest, which may be adverse to such clients. Barclays Wealth is not acting as your agent or investment adviser, and is not representing you in any capacity with respect to any purchase of Notes by you. Barclays Wealth is acting solely as agent for Barclays Bank PLC. If you are considering whether to invest in the Notes through Barclays Wealth, we strongly urge you to seek independent financial and investment advice to assess the merits of such investment.

• Many Economic and Market Factors Will Impact the Value of the Notes—In addition to the level of the Reference Rate 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 Reference Rate;

• the time to maturity of the Notes;

• 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.

HYPOTHETICAL INTEREST RATE AND INTEREST PAYMENT CALCULATIONS

As described above, after the initial Interest Periods for which the Initial Interest Rate is payable, the Notes will pay interest on each Interest Payment Date at an effective per annum interest rate calculated in accordance with the Interest Rate Formula. The following illustrates the process by which the interest rate and interest payment amount are determined for any such Interest Period for which interest is linked to CPI Performance.

Interest Rate Calculation

Step 1: Calculate CPI Performance for the applicable Interest Payment Date.

As described in the prospectus supplement, for any applicable Interest Payment Date, CPI Performance is equal to the annual percentage change in the CPI (as calculated by the Bureau of Labor Statistics) for the period up to and including the stated calendar month prior to the month of the relevant Interest Payment Date (the Reference Month).

Stated mathematically, CPI Performance will be calculated as follows:

CPI Performance =	CPIF – CPII
	CPII

where,

CPI_F = the CPI level for the applicable Reference Month; and

CPI_I = the CPI level for the month one year prior to the applicable Reference Month.

For example, as the Reference Month is specified as the third calendar month prior to the month of the relevant Interest Payment Date, for an Interest Payment Date in June 2011, the applicable Reference Month would be March 2011, and CPI Performance would equal the annual percentage change in the CPI from the March 2010 to March 2011. Similarly, for an Interest Payment Date in March 2011, the applicable Reference Month would be December 2010, and CPI Performance would equal the annual percentage change in the CPI from the December 2009 to December 2010.

The following two examples illustrate how a hypothetical CPI Performance would be calculated for an Interest Payment Date in November 2011 with the Reference Month being August 2011:

Example 1: Assuming a hypothetical CPI level of 204 for August 2010 and 208 for August 2011, CPI Performance for November 2011 would be 1.96%, calculated as follows:

208 – 204	= 1.96%
204

PS–2

Example 2: Assuming a hypothetical CPI level of 204 for August 2010 and 199 for August 2011, CPI Performance for November 2011 would be –2.45%, calculated as follows:

199 – 204	= –2.45%
204

Step 2: Calculate the per annum interest rate for each Interest Payment Date.

The per annum interest rate for any applicable Interest Payment Date payable equals CPI Performance, determined as described above, plus the spread.

In each case, the applicable per annum interest rate for any Interest Payment Date will not be less than the Minimum Interest Rate of 1.00%. If the per annum interest rate for an Interest Payment calculated per the above is less than the Minimum Interest Rate, your interest payment for that Interest Payment Date will be determined using the Minimum Interest Rate.

Step 3: Calculate the interest payment amount payable for each Interest Payment Date.

For each Interest Period, once the Calculation Agent has determined the applicable interest rate per annum, the Calculation Agent will calculate the effective interest rate for the Interest Period by multiplying the annual interest rate determined for that Interest Period by the applicable day count fraction, calculated on a 30/360 basis. The resulting effective interest rate is then multiplied by the relevant principal amount of the Notes to determine the actual interest amount payable on the related Interest Payment Date.

Example Interest Rate and Interest Payment Calculations

The following examples illustrate how the per annum interest rate and interest payment amounts would be calculated for a given Interest Period for which interest is linked to CPI Performance, under different CPI level and CPI Performance scenarios. For purposes of these examples, we have assumed that a CPI level of 208 for the month one year prior to the Reference Month for the relevant Interest Payment Date. The Notes will have a Minimum Interest Rate of 1.00% per annum and the spread of 2.00%. The Notes will have monthly Interest Payment Dates, such that the applicable day count fraction for the applicable quarterly interest (calculated using a 30/360 day count basis) will be 30/360.

These values and assumptions have been chosen arbitrarily for the purpose of these examples, and should not be taken as indicative of any future CPI or CPI performance. Numbers in the table below have been rounded for ease of analysis.

CPI Level for the relevant Reference Month	CPI Performance	Interest Rate per annum 1	Effective Interest Rate3	Interest Payment Amount per $1,000 Note4
198	–4.81%	1.00%2	0.083%	$0.83
200	–3.85%	1.00%2	0.083%	$0.83
204	–1.92%	1.00%2	0.083%	$0.83
206	–0.96%	1.04%	0.087%	$0.87
208	0.00%	2.00%	0.167%	$1.67
210	0.48%	2.48%	0.207%	$2.07
212	1.92%	3.92%	0.327%	$3.27
214	2.88%	4.88%	0.407%	$4.07
216	3.85%	5.85%	0.488%	$4.88
218	4.81%	6.81%	0.568%	$5.68
220	5.77%	7.77%	0.648%	$6.48
222	6.73%	8.73%	0.728%	$7.28

1. Interest rate per annum = CPI Performance + the Spread (2.00%), subject to the Minimum Interest Rate of 1.00%.

2. Where the per annum interest rate calculated is less than the Minimum Interest Rate of 1.00%, the per annum interest rate is set equal to the Minimum Interest Rate.

3. Effective interest rate equals the interest rate per annum multiplied by the day count (30/360).

4. Interest payment amount equals the principal amount times the effective interest rate.

PS–3

Example 1: If CPI Performance for the relevant Interest Payment Date is equal to 1.92%, the applicable per annum interest rate for that Interest Payment Date would be 3.92%, the sum of CPI Performance and the Spread (1.92% + 2.00%).

Based on the per annum interest rates determined per the above, you would receive an interest payment of $3.27 per $1,000 Note on the Interest Payment Date, calculated as follows:

Effective Interest Rate = 3.92% × (30/360) = 0.327%

          Interest Payment = $1,000 × 0.327% = $3.27

Example 2: If CPI Performance for the relevant Interest Payment Date is equal to –3.85%, the applicable per annum interest rate for that Interest Payment Date would be –1.85%, the sum of CPI Performance and the Spread (–3.85% + 2.00%). Since the per annum interest rate so determined is less than the Minimum Interest Rate of 1.00%, the applicable per annum interest rate would be equal to the Minimum Interest Rate of 1.00%, and you would receive $0.83 per $1,000 Note on the related monthly Interest Payment Date.

Example 3: If CPI Performance for the relevant Interest Payment Date is equal to 5.77%, the applicable per annum interest rate for that Interest Payment Date would be 7.77%, the sum of CPI Performance and the Spread (5.77% + 2.00%). You would receive an interest payment $6.48 on the related quarterly Interest Payment Date, calculate as follows:

Effective Interest Rate = 7.77% × (30/360) = 0.648%

Interest Payment = $1,000 × 0.648% = $6.48

HISTORICAL REFERENCE RATE INFORMATION

The following table sets forth historical CPI levels and CPI growth for the months indicated in 2005 through 2009, and for 2010 through November 2010. Historical CPI levels and growth should not be taken as an indication of future levels or percentage increases or decreases of the Reference Rate, and no assurance can be given that the Reference Rate will increase sufficiently to cause the holders of Notes to receive interest payments on each or any Interest Payment Date.

UNITED STATES FEDERAL INCOME TAX TREATMENT

The following discussion (in conjunction with the discussion in the prospectus supplement) summarizes certain of the material U.S. federal income tax consequences of the purchase, beneficial ownership, and disposition of Notes. This summary supplements the section “Certain U.S. Federal Income Tax Considerations” in the prospectus supplement and supersedes it to the extent inconsistent therewith.

We intend to treat the Notes as contingent payment debt instruments subject to taxation as described under the heading “Certain U.S. Federal Income Tax Considerations—U.S. Federal Income Tax Treatment of the Notes as Indebtedness for U.S. Federal Income Tax Purposes—Contingent Payment Debt Instruments” in the prospectus supplement. As a result, you may be required to include original issue discount (“OID”) in income during your ownership of the Notes in excess of any cash payments made with respect to the Notes in such taxable year. We intend to treat the excess of any non-contingent payments on the Notes (i.e., the initial 4.25% interest rate) in an accrual period over the product of the comparable yield of the Notes and their adjusted issue price as a nontaxable return of principal which, in turn, will reduce the “adjusted issue price” of the Notes. Additionally, you will generally be required to recognize ordinary income on the gain, if any, realized on a sale, upon maturity, or other disposition of the Notes. Pursuant to the terms of the Notes, you agree to treat the Notes consistent with our treatment for all U.S. federal income tax purposes.

You may obtain the comparable yield and the projected payment schedule of the Notes by requesting them from Director—Structuring, Investor Solutions Americas, at (212) 412-1101. The comparable yield and the projected payment schedule are neither predictions nor guarantees of the actual yield on the Notes.

Because there are no statutory provisions, regulations, published rulings or judicial decisions addressing the characterization for U.S. federal income tax purposes of securities with terms that are substantially the same as those of the Notes, other characterizations and treatments are possible. As a result, the timing and character of income in respect of the Notes might differ from the treatment described above.

Because Barclays Capital Inc. proposes to offer the Notes at varying prices, the “issue price” of the Notes for federal income tax purposes may differ from the amount you pay for the Notes. You may obtain the issue price of each Note by contacting Director—Structuring, Investor Solutions Americas at (212) 412-1101. If you purchase the Notes for an amount that differs from their issue price, you may be subject to special tax rules as described in “Certain U.S. Federal Income Tax Considerations—U.S. Federal Income Tax Treatment of the Notes as Indebtedness for U.S. Federal Income Tax Purposes—Contingent Payment Debt Instruments” in the accompanying prospectus supplement (in particular, the rules that apply when a U.S. holder purchases a contingent payment debt instrument for an amount that differs from the adjusted issue price of that contingent payment debt instrument at the time of the purchase). You should consult your own tax advisor regarding these rules.

3.8% Medicare Tax On “Net Investment Income”

Beginning in 2013, U.S. holders that are individuals, estates, and certain trusts will be subject to an additional 3.8% tax on all or a portion of their “net investment income,” which may include the interest payments and any gain realized with respect to the Notes, to the extent of their net investment income that when added to their other modified adjusted gross income, exceeds $200,000 for an unmarried individual, $250,000 for a married taxpayer filing a joint return (or a surviving spouse), or $125,000 for a married individual filing a separate return. U.S. holders should consult their advisors with respect to their consequences with respect to the 3.8% Medicare tax.

Information Reporting

Holders that are individuals (and, to the extent provided in future regulations, entities) may be subject to certain foreign financial asset reporting obligations with respect to their Notes if the aggregate value of their Notes and their other “specified foreign financial assets” exceeds $50,000. Significant penalties can apply if a holder fails to disclose its specified foreign financial assets. This information reporting requirement is generally applicable for taxable years beginning after March 18, 2010. We urge you to consult your tax advisor with respect to this and other reporting obligations with respect to your Notes.

PROSPECTIVE PURCHASERS SHOULD CONSULT THEIR TAX ADVISORS AS TO THE FEDERAL, STATE, LOCAL, AND OTHER TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF NOTES.

Your purchase of a Note in an Individual Retirement Account (an “IRA”), will be deemed to be a representation and warranty by you, as a fiduciary of the IRA and also on behalf of the IRA, that (i) neither the issuer, the placement agent nor any of their respective affiliates has or exercises any discretionary authority or control or acts in a fiduciary capacity with respect to the IRA assets used to purchase the Note or renders investment advice (within the meaning of Section 3(21)(A)(ii) of the Employee Retirement Income Security Act (“ERISA”)) with respect to any such IRA assets and (ii) in connection with the purchase of the Note, the IRA will pay no more than “adequate consideration” (within the meaning of Section 408(b)(17) of ERISA) and in connection with any redemption of the Note pursuant to its terms will receive at least adequate consideration, and, in making the foregoing representations and warranties, you have (x) applied sound business principles in determining whether fair market value will be paid, and (y) made such determination acting in good faith.

For additional ERISA considerations, see “Employee Retirement Income Security Act” in the prospectus supplement.
