FREQUENTLY ASKED QUESTIONS About iPath® Exchange Traded Notes (ETNs) iPath® Exchange Traded Notes are innovative investment products from Barclays that seek to provide investors with a new way to access the returns of a market or strategy, less investor fees. The following are answers to questions financial professionals and individuals commonly ask about iPath® Exchange Traded Notes. iPATH ETNs OVERVIEW What are iPath Exchange Traded Notes? iPath Exchange Traded Notes (ETNs) are senior, unsecured, unsubordinated debt securities issued by Barclays Bank PLC. They are designed to provide investors with a way to access the returns of market benchmarks or strategies. ETNs are not equities or index funds, but they do share several characteristics. For example, like equities, they trade on an exchange and can be shorted.1 Like index funds, they are linked to the return of a benchmark index. What are the advantages of iPath ETNs? iPath ETNs provide investors with exposure to the returns of market benchmarks, less investor fees, with easy transferability and an exchange listing. The ETN structure is designed to provide investors the opportunity to access previously expensive or difficult-to-reach market sectors or strategies through an exchange traded product. How are the returns of iPath ETNs calculated? iPath ETNs are designed to provide investors a return that is linked to the performance of a market index, less investor fees. How do I buy an iPath ETN? The iPath ETNs currently available are listed on NYSE Arca (and in certain cases other major exchanges) and are available for purchase similar to other publicly traded securities. How do I sell an iPath ETN? Investors can liquidate iPath ETNs one of three ways: n Sell in the secondary market during trading hours. n Redeem a large block of securities, typically 50,000 units directly to the issuer, Barclays Bank PLC, subject to the procedures described in the relevant prospectus.2 A redemption charge will apply to certain iPath ETNs. n Hold until maturity and receive a cash payment from the issuer, Barclays Bank PLC, equal to the principal amount of the securities times an index factor and any other applicable costs on the final valuation date (as described in the relevant prospectus) minus the investor fee on the final valuation date. Do the iPath ETNs currently available make interest payments? No. Do the iPath ETNs currently available make dividend distributions? No. 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. 1. With short sales, you risk paying more for a security than you received from its sale. 2. The issuer may from time to time in its sole discretion reduce, in part or in whole, the minimum redemption amount. Any such reduction will be applied on a consistent basis for all holders of units at the time the reduction becomes effective.

2 iPath Do the iPath ETNs currently available offer a principal protection feature? No. Investors will receive a return based on the performance of the index to which the iPath ETN is linked, less investor fees and any other applicable costs. The index level may go up or down, and investors may not recover their principal once investor fees and costs are deducted. Are iPath ETNs rated? No. The iPath ETNs are not rated, but rely on the ratings of their issuer, Barclays Bank PLC.3 Who is the issuer? Barclays Bank PLC and its subsidiary undertakings (taken together, the “Group”) is a major global financial services provider engaged in retail and commercial banking, credit cards, investment banking, wealth management and investment management services. The Group operates in many countries around the world. The whole of the issued ordinary share capital of Barclays Bank PLC is beneficially owned by Barclays PLC, which is the ultimate holding company of the Group. For further information about Barclays, please visit our website www.barclays.com. Who is Barclays Capital Inc.? Barclays Capital Inc. will act as the issuer’s agent in connection with the distribution of the iPath ETNs. Barclays Capital Inc. is an affiliate of Barclays Bank PLC and is a registered U.S. broker/dealer regulated by the SEC and FINRA. What is BlackRock’s role? BlackRock’s broker/dealer affiliate, BlackRock Fund Distribution Company, will engage in the promotion of iPath ETNs. Do iPath ETNs have voting rights? No. The iPath ETNs are debt securities and have no voting rights. Are iPath ETNs registered? Yes. The iPath ETNs are registered under the Securities Act of 1933. Does the Commodity Futures Trade Commission (CFTC) regulate the iPath ETNs linked to commodity indexes? No. iPath ETNs are debt securities issued by Barclays Bank PLC and are not regulated by the CFTC; however, futures contracts underlying the relevant market index may be regulated by the CFTC. What is an index multiplier and how is it applicable to certain iPath ETNs? Some iPath ETNs apply an index multiplier for purposes of calculating the closing indicative note value on each calendar day. The effect of the index multiplier is to establish the rate at which the value of the ETN changes (either directly or inversely) in response to changes in the level of the relevant index. Where can I find additional information about iPath ETNs? Additional information is available at www.iPathETN.com. TRADING iPATH ETNs Where are iPath ETNs listed? The iPath ETNs currently available are listed on NYSE Arca (and in certain cases other major exchanges). When can I buy or sell iPath ETNs? iPath ETNs can be bought or sold anytime during market hours. Can the iPath ETNs currently available be shorted?4 Yes, on an uptick or a downtick and subject to the ability to locate shares to borrow. Is there a minimum trade size for iPath ETNs? No. iPath ETNs can be bought and sold at their market price on the secondary market similar to other publicly traded securities. 3. Credit ratings are subject to revision or withdrawal at any time by the assigning rating organization, which may have an adverse effect on the market price or marketability of the iPath ETNs. 4. With short sales, you risk paying more for a security than you received from its sale.

Frequently Asked Questions About iPath® Exchange Traded Notes (ETNs) 3 TABLE 1 Differences and Similarities Between ETNs and Exchange Traded Funds (ETFs) Both ETNs and ETFs provide investors access to the returns of various market benchmarks. However, ETNs are senior, unsecured debt securities issued by Barclays Bank PLC, whereas ETFs are typically registered investment companies and are collateralized by an underlying portfolio of securities. ETNs ETFs Liquidity Daily on exchange Daily on exchange Registration Securities Act of 1933 Investment Company Act of 1940 Recourse Issuer credit Portfolio of securities Principal risk Market and issuer risk Market risk Institutional size redemption Daily to the issuer Daily via custodian Short sales Yes, on an uptick or a downtick Yes, on an uptick or a downtick How can I find iPath ETNs on Bloomberg? Information regarding iPath ETNs can be found on Bloomberg by typing the relevant ETN’s trading symbol, then the “Equity” key, then “Go.” For example, for information regarding the iPath® S&P GSCI™ Total Return Index ETN, type: GSP < Equity > < Go >. Is a net asset value (NAV) calculated? No. As iPath ETNs are debt securities, and not mutual funds, they will not have a NAV. Is an intrinsic value calculated? An intraday “indicative value” meant to approximate the intrinsic economic value of each iPath ETN is calculated and published by Bloomberg or a successor. Additionally, the daily indicative value of each iPath ETN is calculated and published at the end of each trading day at www.iPathETN.com. For a more complete description of how the daily indicative value is calculated for each iPath ETN, please see the applicable product page and Pricing Supplement at www.iPathETN.com. Do the iPath ETNs trade at their indicative value? The indicative value calculation is provided for reference purposes only. It is not intended as a price or quotation, or as an offer or solicitation for the purchase, sale, redemption or termination of the iPath ETNs, nor does it reflect hedging or transaction costs, credit considerations, market liquidity or bid-offer spreads. Published index levels from the sponsors of the indexes underlying the iPath ETNs may occasionally be subject to delay or postponement. Any such delays or postponements will affect the current index level and therefore the indicative value of your iPath ETNs. Index levels provided by the sponsors of the indexes underlying the iPath ETNs do not necessarily reflect the depth and liquidity of the underlying relevant market. For this reason and others, the actual trading price of the iPath ETNs may be different from their indicative value. In addition to being available for trading on an exchange, the early redemption feature allows a large block of securities, typically 50,000 units of a particular iPath ETN, to be redeemed directly to Barclays Bank PLC for the applicable redemption value, as described in the applicable Pricing Supplement. The historical daily indicative value is published each day at www.iPathETN.com. The redemption feature is intended to induce arbitrageurs to counteract any trading of the iPath ETNs at a premium or discount to their indicative value, though there can be no assurance that arbitrageurs will employ the redemption feature in this manner.

4 iPath How can iPath ETNs be redeemed directly to the issuer prior to the maturity date? Investors may redeem a large block of securities, typically at least 50,000 units of a particular iPath ETN, directly to the issuer, subject to the procedures described in the relevant prospectus. A redemption charge may apply. What is the redemption charge? The redemption charge is a one-time transaction charge imposed only in the case of early redemptions for certain iPath ETNs. The charge is intended to allow the issuer to recoup brokerage and other costs incurred in connection with an early redemption (although the proceeds from the charge may be more or less than such costs). Investors transacting on the secondary market will not incur a redemption charge. What is an automatic termination event?z An automatic termination event is an automatic redemption applicable to certain ETNs at a specific ETN value (“automatic termination trigger”), as defined in the relevant prospectus. Market conditions may contribute to the occurrence of an automatic termination event. In the occurrence of an automatic termination event, Barclays will deliver a notice of redemption and automatically redeem the relevant ETN at the automatic redemption value. Please refer to the relevant prospectus for further details on the automatic termination event redemption trigger, timing and processes. If Barclays Bank PLC’s credit rating is downgraded, what happens to the indicative value? The indicative value calculation of the iPath ETNs will not change in response to a Barclays Bank PLC credit event. However, the trading price of the iPath ETNs may be adversely impacted. Is there a capacity constraint with respect to iPath ETNs? Should demand for any iPath ETN exceed the initial amount of securities issued, subsequent issuances may be made under the registration statement. The terms of the new issue—maturity date, investor fee, ticker, CUSIP—will be the same as the original issue, and it is expected that both issues would be immediately fungible. Depending on market factors beyond the control of Barclays Bank PLC, certain iPath ETNs may be suspended from further sales from inventory and/or further issuances.5 Daily redemptions at the option of the holders of iPath ETNs are typically not affected by suspensions, nor are Barclays Bank PLC’s lending activities from existing inventory with respect to iPath ETNs typically affected by suspensions. It is possible that a suspension, as described above, may influence the market value of iPath ETNs. Limitations on issuance and sale implemented may cause an imbalance of supply and demand in the secondary market for iPath ETNs, which may cause them to trade at a premium or discount in relation to their indicative value. Therefore, any purchase of iPath ETNs in the secondary market may be at a purchase price significantly different from their indicative value. iPATH LEVERAGED ETNs How are the returns of iPath leveraged ETNs calculated? iPath leveraged ETNs are designed to provide investors with a leveraged return that is linked to the performance, or inverse performance, of a market benchmark less applicable charges, costs and fees. 5. As will be described in further detail in the applicable prospectus relating to the iPath ETNs.

Frequently Asked Questions About iPath® Exchange Traded Notes (ETNs) 5 Where is their value published? An intraday indicative note value (“IINV”), which is meant to approximate the intrinsic economic value of each series of iPath leveraged ETN, will be calculated by the calculation agent on an ongoing basis from the initial valuation date to the final valuation date. During the hours on which trading is generally conducted on NYSE Arca, NYSE Arca or a successor will calculate and publish the IINV for each iPath leveraged ETN every 15 seconds under the applicable ticker symbol. Additionally, a closing indicative note value (“CINV”) for each iPath leveraged ETN will be published by NYSE Arca on each valuation date under the applicable ticker symbol. For a more complete description of how the IINV and CINV are calculated for each series of iPath leveraged ETNs, please see the relevant prospectus. What is the automatic redemption feature? In order to mitigate the risk to the issuer that the value of the ETNs equals a negative value, there will be an automatic redemption of any series of the iPath leveraged ETNs if, on any calendar day prior to or on the final valuation date, the IINV is less than or equal to the applicable automatic termination level specified below per ETN. Upon the occurrence of an automatic termination event, investors in that series of iPath leveraged ETNs will receive a redemption amount that will be significantly less than the issue price and will receive no greater than the automatic termination level specified below per ETN. Accordingly, you may lose some or all of your principal if you invest in the iPath leveraged ETNs. Where can I find the closing indicative note value? The closing indicative note value (“CINV”) will be published by NYSE Arca on each valuation date under the applicable ticker symbols. Will the iPath leveraged ETNs track a fixed multiple of the daily or monthly performance of an underlying index? Unlike some leveraged investments, the iPath leveraged ETNs do not track a fixed multiple of the daily or monthly performance of an underlying index. Instead, on any given day the indicative value of any series of iPath leveraged ETNs will change by a multiple of the underlying index performance that is variable and depends, in part, on the then current IINV of that series of iPath leveraged ETNs. In order to allow investors to monitor the ratio of percentage daily changes in the IINV to daily index percentage returns, NYSE Arca (or a successor entity) will calculate and publish the “Participation” for each series iPath leveraged ETNs every 15 seconds during the hours on which trading is generally conducted on the NYSE Arca. For each series of iPath leveraged ETNs, the participation is calculated by dividing the amount per ETN that is notionally exposed to the underlying index by the then current IINV of that ETN. TABLE 2 Where Are They Traded? The iPath leveraged ETNs are listed on the NYSE Arca stock exchange. The current list of the iPath leveraged ETNs includes the following tickers: Exchange Stock Automatic Termination Name Ticker Exchange Level (per ETN) iPath® Long Extended Russell 1000® TR Index ETN ROLA NYSE Arca $10.00 iPath® Short Extended Russell 1000® TR Index ETN ROSA NYSE Arca $10.00 iPath® Long Extended Russell 2000® TR Index ETN RTLA NYSE Arca $15.00 iPath® Short Extended Russell 2000® TR Index ETN RTSA NYSE Arca $15.00 iPath® Long Extended S&P 500® TR Index ETN SFLA NYSE Arca $10.00 iPath® Short Extended S&P 500® TR Index ETN SFSA NYSE Arca $10.00 iPath® Long Enhanced MSCI EAFE® Index ETN MFLA NYSE Arca $25.00 iPath® Short Enhanced MSCI EAFE® Index ETN MFSA NYSE Arca $37.50 iPath® Long Enhanced MSCI Emerging Markets Index ETN EMLB NYSE Arca $25.00 iPath® Short Enhanced MSCI Emerging Markets Index ETN EMSA NYSE Arca $45.00 iPath® Long Enhanced S&P 500 VIX Mid-Term Futures™ ETN VZZ NYSE Arca $10.00

6 iPath What are the fees for the iPath leveraged ETNs? As the iPath leveraged ETNs seek to replicate a long or short investment in an underlying index, certain charges, costs and fees are built into the calculation of the CINV and the IINV. The iPath long leveraged ETNs charge an annualized investor fee and an annualized financing charge on notional cash amounts underlying each iPath long leveraged ETN,6 and the iPath short leveraged ETNs charge an annualized investor fee and an annualized index borrow cost on the notional cash amounts underlying each iPath short leveraged ETN (offset by annualized interest). The notional cash amounts of the iPath long leveraged ETNs will vary according to the financing rate and fee rate, both as defined in the applicable prospectus, and the notional cash amounts of the iPath short leveraged ETNs will vary according to the fee rate, the borrow rate and the T-Bill rate, all as defined in the applicable prospectus, and will not in general move in tandem with the underlying index or the IINV or CINV. Therefore, under certain circumstances and in particular where the financing level, as defined in the applicable long prospectus, or T-bill amount, as defined in the applicable short prospectus, is a high multiple of the applicable CINV, the fees may represent a significant percentage of the applicable CINV. For full details of the accrued fees, charges and costs for the iPath leveraged ETNs, and hypothetical examples as to how these can affect the performance of the ETNs, investors should consult the applicable prospectus. INFORMATION FOR ADVISORS Broker/dealers are reminded to consider FINRA Notice to Members 05–59 (September 2005) before recommending iPath ETNs to their customers. Is a Series 3 license required to sell iPath ETNs? No. TABLE 3 Differences and Similarities Between iPath Leveraged ETNs and Leveraged ETFs Both iPath leveraged ETNs and leveraged ETFs provide investors with access to the leveraged returns of various market benchmarks. However, the iPath leveraged ETNs are senior, unsecured debt securities issued by Barclays Bank PLC, whereas ETFs are typically registered investment companies and are collateralized by an underlying portfolio of securities. In addition, the iPath leveraged ETNs seek to provide investors with an alternative form of leveraged long (or short) investments to leveraged ETFs, which typically track a daily or monthly multiple of an index’s returns. Instead, the iPath leveraged ETNs track a fixed multiple of underlying index performance over the term of the ETNs.

Because the daily investor fee accrues as part of the financing level and the daily financing charge is calculated on the basis of the financing level, a portion of the daily financing charge will reflect the incremental increase of the financing level attributable to the accrued daily investor fee.

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 investing directly in an index or in any particular 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 level of the relevant index has increased or decreased (as may be applicable to the particular series of Securities). 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.
