times the index factor, calculated on a daily basis in the following manner: The investor fee on

the inception date will equal zero. On each subsequent calendar day until maturity or early

principal amount of your securities times the index factor on that day (or, if such day is not a

index factor on any given day will be equal to the closing value of the index on that day divided

by the initial index level. The initial index level is the closing value of the index on the inception

date of the securities.

Index returns are for illustrative purposes only and do not represent actual iPath ETN performance. Index performance returns do not reflect any

management fees, transaction costs or expenses. Indexes are unmanaged and one cannot invest directly in an index. Past performance does not

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.

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 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.

iPath ETNs typically have lower investor fees than currently existing mutual funds that invest in similar

markets and are available to retail investors. Buying and selling iPath ETNs will result in brokerage

commissions.

BGINA and its affiliates, and BCI and its affiliates do not provide tax advice and nothing contained

herein should be construed to be tax advice. Please be advised that any discussion of U.S. tax matters

contained herein (including any attachments) (i) is not intended or written to be used, and cannot be

used, by you for the purpose of avoiding U.S. tax-related penalties; and (ii) was written to support the

promotion or marketing of the transactions or other matters addressed herein. Accordingly, you should

seek advice based on your particular circumstances from an independent tax advisor.

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. The current or “spot” prices of the underlying physical commodities may also

affect, in a volatile and 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 your Securities in varying

ways.

In addition to factors affecting commodities generally, index components composed of futures

contracts on industrial metals or energy-related commodities may be subject to additional factors

specific to industrial metals or energy-related commodities that might cause price volatility. These may

include changes in the level of industrial or commercial activity using industrial metals or with high

levels of energy demand; the availability and price of substitutes such as man-made or synthetic

substitutes or alternative sources of energy; disruptions in the supply chain; adjustments to inventory;

variations in production costs; costs associated with regulatory compliance, including environmental

regulations; and changes in industrial, government and consumer demand, both in individual consuming

nations and internationally. Index components composed of futures contracts on agricultural products

may be subject to additional factors specific to agricultural products that might cause price volatility.

These may include weather conditions, including floods, drought and freezing conditions; pestilence;

changes in government policies; planting decisions; and changes in demand for agricultural products,

both with end users and as inputs into various industries. Index components composed of futures

contracts on precious metals may be subject to additional factors specific to precious metals that

might cause price volatility. These may include disruptions in the supply chain, variations in production

costs, costs associated with regulatory compliance, including environmental regulations, changes in

industrial, government and consumer demand, and in the case of gold and silver, precious metal leasing

rates, currency exchange rates, the level of economic growth and inflation and the degree to which

consumers, governments, corporate and financial institutions hold physical gold or silver as a safe

haven asset (hoarding) which may be caused by a banking crisis/recovery, a rapid change in the value

of other assets (both financial and physical) or changes in the level of geopolitical tension.
