An investment in iPath ETNs involves risks, including possible loss of principal. For a description of the main risks see “Risk Factors” in the applicable prospectus.

Barclays Bank PLC has filed a registration statement (including a prospectus) with the SEC for the offering to which this communication relates. Before you invest, you should read the prospectus and other documents Barclays Bank PLC has filed with the SEC for more complete information about the issuer and this offering. You may get these documents for free by visiting www.iPathETN.com or EDGAR on the SEC website at www.sec.gov. Alternatively, Barclays Bank PLC will arrange for Barclays Capital Inc. to send you the prospectus if you request it by calling toll-free 1-877-76-iPATH, or you may request a copy from any other dealer participating in the offering.

Barclays Global Investors Services, a subsidiary of Barclays Global Investors, N.A. (“BGINA”), assists in the promotion of the Securities. Barclays Global Investors, N.A. and Barclays Capital Inc. (“BCI”) are affiliates of Barclays Bank PLC.

iPath ETNs (the “Securities”) are unsecured obligations of Barclays Bank PLC and are not secured debt. The Securities are riskier than ordinary unsecured debt securities and have no principal protection. Risks of investing in the Securities include limited portfolio diversification, trade price fluctuations, uncertain principal repayment, and illiquidity. Investing in the Securities is not equivalent to direct investment in index or index components. The investor fee will reduce the amount of your return at maturity or on redemption, and as a result you may receive less than the principal amount of your investment at maturity or upon redemption of your Securities even if the value of the relevant index has increased. An investment in iPath ETNs may not be suitable for all investors.

This material is not a confirmation of a transaction. We are willing to discuss it with you on the assumption that you have sufficient knowledge, experience and professional advice to understand and make your own independent evaluation of the merits and risks of the proposed structures. This should not be viewed as investment, tax, accounting or other advice. If applicable, this material may be subject to completion or change by subsequent term sheets or other summaries of terms and conditions.

Any information relating to performance contained in these materials is illustrative and no assurance is given that any indicated returns, performance or results will be achieved. All information, terms and pricing set forth herein reflect our judgment at the date and time hereof and if applicable, subject to change by subsequent term sheets or other summaries of terms and conditions.

In the event that Barclays were to enter into a transaction with you, Barclays will not do so as your fiduciary or advisor. Barclays will generally conduct its business without regard to the consequences of such conduct (adverse or otherwise) to you. Barclays, or any of its affiliates may from time to time act as manager, co-manager or underwriter of a public offering or otherwise, in the capacity of principal or agent, deal in, hold or act as market makers or advisors, brokers or commercial and/or investment bankers in relation to the securities or related derivatives that are discussed herein.

The Securities may be sold throughout the day on the exchange through any brokerage account. There are restrictions on the minimum number of Securities you may redeem directly with the Issuer, and on the dates on which you may redeem them, as specified in the applicable prospectus. Commissions may apply and there are tax consequences in the event of sale, redemption or maturity of Securities. Sales in the secondary market may result in significant losses.

The index components for iPath ETNs linked to commodities indexes are concentrated in the commodities sector. The market value of the Securities may be influenced by many unpredictable factors, including, where applicable, highly volatile commodities prices, changes in supply and demand relationships; weather; agriculture; trade; pestilence; changes in interest rates; and monetary and other governmental policies, action and inaction. Index components that track the performance of a single commodity, or index components concentrated in a single sector, are speculative and may typically exhibit higher volatility, and may bear unique risks specific to such commodity or sector. The current “spot” prices of the underlying physical commodities may also affect, in a volatile an inconsistent manner, the prices of futures contracts in respect of the relevant commodity. These factors may affect the value of the index and the value of the Securities in varying ways.

The index component is composed of futures contracts on copper, which is an industrial metal. Consequently, in addition to factors affecting commodities generally, the index component may be subject to a number of additional factors specific to industrial metals that might cause price volatility, including changes in the level of industrial activity using industrial metals (including the availability of substitutes such as man-made or synthetic substitutes); disruptions in the supply chain, from mining to storage to smelting or refining; adjustments to inventory; variations in production costs, including storage, labor and energy costs; costs associated with regulatory compliance, including environmental regulations; and changes in industrial, government and consumer demand, both in individual consuming nations and internationally.
