FOR INSTITUTIONAL INVESTORS ONLY FOR INFORMATION ONLY NOT FOR FURTHER DISTRIBUTION Barclays Backwardation Long Short Index: Executive Summary Barclays Backwardation Long Short Index is designed to provide enhanced returns from commodities markets: Selection criteria is based on the following: – Different commodities exhibit different supply and demand fundamentals – Historically, tight inventories have generally been correlated with higher performance – Target commodities with the greatest potential for positive returns based on the level of backwardation Backwardation Long Short Index uses a non-discretionary methodology – Evaluate the degree of backwardation in the futures price curve from a universe of 23 commodities – Take a long position1 in the 6 commodities with the highest observed backwardation3 – Take a short position2 in the 6 commodities with the lowest observed backwardation3 Barclays Backwardation Long Short Index is independently calculated by Barclays Index, Portfolio and Risk Solutions (IPRS) Barclays Bank PLC is the Index Sponsor of the Barclays Backwardation Long Short Index 1This denotes an investment in a proprietary Barclays single commodity index for which the underlying contract is deferred by three months 2This denotes an investment in a proprietary Barclays single commodity index for which the underlying contract is the next nearby or front month contract. 3 See appendix for explanation of “backwardation” 2 Barclays

FOR INSTITUTIONAL INVESTORS ONLY FOR INFORMATION ONLY NOT FOR FURTHER DISTRIBUTION The Value Proposition The underlying premise of the Backwardation Selection Process is based on the observation that, historically, commodities with low inventories have tended to outperform commodities with high inventories. Lower Inventories Greater Upside Potential Why are low inventories related to higher potential return Inventories can act as a shock absorber for commodity prices by providing a source for commodity supply in the case of a demand spike or supply disruption. When inventory levels are low, they may be unable to fulfill their role as a commodity price shock absorber Commodity prices can become more susceptible to upward price shocks in the case of increased demand or reduced supply.

FOR INSTITUTIONAL INVESTORS ONLY FOR INFORMATION ONLY NOT FOR FURTHER DISTRIBUTION Commodity Curve Shape– Backwardation and Contango Roll yield is an important component of commodity index returns and will depend on the shape of the futures curve, i.e., backwardated (downward sloping) or contango (upward sloping). to expiry to expiry Assuming the price and shape of the futures curve remain constant and a long position in a futures contract is rolled: In backwardation, a more expensive contract will be sold and a cheaper contract purchased, creating a positive “roll yield”, which can positively impact a long position in a futures contract. In contango, a cheaper contract will be sold and a more expensive contract purchased, creating a negative “roll yield”, which can negatively impact a long position in a futures contract. 12 Barclays

FOR INSTITUTIONAL INVESTORS ONLY FOR INFORMATION ONLY NOT FOR FURTHER DISTRIBUTION Risk Factors Some of the risks related to securities or products that may be linked to Barclays commodity indices or underlying reference assets (“Structured Investments”) are described below. Before investing in any Structured Investment, you should read the relevant prospectus or disclosure statement for a detailed explanation of the terms, risks, tax treatment and other relevant information of the investment. We also urge you to consult your financial, tax and legal advisors before investing. The Strategy Employed by the Barclays Backwardation Long Short Index Excess Return is not Guaranteed to Succeed The Barclays commodity index referenced in this presentation is based on the premise(s) or strategies referenced herein. There is no assurance that this strategy will be successful and, accordingly, no assurances can be made that any Barclays commodity index or reference asset will appreciate during the term of any Structured Investment. The Backwardation Long Short Index Total Return utilizes the Backwardation Selection Process each month, which is a proprietary method intended to select commodities that have the highest degree of observed backwardation (or least degree of contango). The Backwardation Selection Process evaluates the degree of backwardation in the futures price curve for 23 commodities and selects six commodities each month with the highest degree of observed backwardation and six commodities with the lowest degree of observed backwardation. The Backwardation Selection Process may not effectively measure the degree of backwardation or capture the benefits of this measure. Furthermore, even if the Backwardation Selection Process is successful in identifying the commodities that exhibit the highest and lowest degree of backwardation within the universe of the commodities underlying the Barclays Backwardation Long Short Index Excess Return, the degree of backwardation at any given time is not necessarily an accurate indication of future prices at relevant times during the term of any Structured Investment linked to the index. If the components of the Long Portfolio decrease in value or if the Short Portfolio increases by an amount enough to offset the performance of the Long Portfolio, the level of the Barclays Backwardation Long Short Index Excess Return, and market value of any Structured Investment linked to such index, will decline. If the Backwardation Selection Process proves to be ineffective, then an investment in any Structured Investment linked to such index may underperform a corresponding investment in instruments linked to other commodity indices or other backwardation measures, possibly by a substantial margin. The issuance of Structured Investments should not be deemed an assurance or guarantee by Barclays Bank PLC or any of its affiliates that the level of the underlying reference asset will increase or that the Structured Investments will generate a positive return. Credit of Issuer: Structured Investments offered by Barclays Bank PLC are not either directly or indirectly an obligation of any third party. Any payment to be made on the Structured Investments, including any payment of principal, depends on the ability of Barclays Bank PLC as the case may be, to meet its obligations as they come due. As a result, the actual and perceived creditworthiness of Barclays Bank PLC may affect the market value of the Structured Investments. In the event Barclays Bank PLC were to default on its obligations, an investor may not receive the amounts owed to an investor under the terms of a Structured Investment. No rights to the reference asset As holders of the Structured Investments, investors will not have any rights (including any voting rights or rights to receive cash dividends or other distributions or any rights to receive the underlying commodities or exchange-traded or over-the-counter instruments based on these commodities) that the holders of any reference asset or components of the reference asset would have. Limited liquidity Investors should be willing to hold Structured Investments to maturity. There may be little or no secondary market for Structured Investments. Barclays Capital Inc. or other affiliates of Barclays Bank PLC intend to make a secondary market in the Structured Investments. If they do, however, they are not required to do so and may stop at any time, and there may not be a trading market in the Structured Investments. If an investor sells Structured Investments prior to their maturity, an investor may have to sell them at a substantial loss. Certain built-in costs are likely to adversely affect the value of the Structured Investments prior to maturity The original issue price of the Structured Investments includes the agent’s commission and the cost of hedging our obligations under the Structured Investments. As a result, assuming no change in market conditions or any other relevant factors, the price, if any, at which Barclays Capital Inc. or other affiliates of Barclays Bank PLC will be willing to purchase Structured Investments from the investor in secondary market transactions may be lower than the original issue price, and any sale prior to the maturity date of the Structured Investment could result in a substantial loss to the investor. 13 Barclays

FOR INSTITUTIONAL INVESTORS ONLY FOR INFORMATION ONLY NOT FOR FURTHER DISTRIBUTION Risk Factors Your own evaluation of the merits In connection with any purchase of a Structured Investment, we urge you to consult your own financial, tax and legal advisors as to the risks involved in an investment in the product and to investigate the reference asset and not rely on our views in any respect. You should make a complete investigation as to the merits of an investment in a Structured Investment before investing. Historical results not indicative of future performance The historical or hypothetical performance of the reference asset should not be taken as an indication of the future performance of the reference asset. It is impossible to predict whether the level, value or price of the reference asset will fall or rise during the term of the Structured Investments, in particular in the environment in recent periods which has been characterized by unprecedented volatility across a wide range of asset classes. Past fluctuations and trends in the reference assets are not necessarily indicative of fluctuations or trends that may occur in the future. Market risk The return, if any, on Structured Investments is dependent on the performance of the reference asset to which it is linked. Thus, changes in the level, value or price of the reference asset will determine the amount payable on the Structured Investment. Unless a Structured Investment is fully principal protected (in which case, all payments on the Structured Investment are subject to the credit risk of Barclays Bank PLC), if the level, value or price of the reference asset declines, you may lose some or all of your investment at maturity. Price volatility Movements in the levels, values or prices of the reference assets and their respective components are unpredictable and volatile, and are influenced by complex and interrelated political, economic, financial, regulatory, geographic, judicial and other factors. As a result, it is impossible to predict whether the levels, values or prices of the reference assets will rise or fall during the term of any Structured Investment. Changes in the levels, values or prices of the reference assets will determine the payment on the Structured Investments. Therefore, you may receive less, and potentially substantially less, than the amount you initially invested in the Structured Investments if the levels, values or prices of the reference assets decline. Unless your Structured Investment is fully principal protected (in which case, all payments on the Structured Investment are subject to the credit risk of Barclays Bank PLC as the issuer), you should be willing and able to bear the loss of some or all of your investment. Many unpredictable factors, including economic and market factors, will impact the value of the Structured Investments In addition to the level, value or price of the reference asset on any day, the market value of the Structured Investments 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 asset or its underlying components; the time to maturity of the Structured Investments; interest and yield rates in the market generally; a variety of economic, financial, political, regulatory or judicial events; supply and demand for the Structured Investments; and the creditworthiness of the issuer, including actual or anticipated downgrades in the credit ratings of the issuer. 14 Barclays

FOR INSTITUTIONAL INVESTORS ONLY FOR INFORMATION ONLY NOT FOR FURTHER DISTRIBUTION Risk Factors Potential conflicts of interests Barclays Bank PLC or one of its affiliates could serve as the calculation agent for the Structured Investments. The calculation agent will make determinations related to the Structured Investments, including calculating the amounts payable to you under the Structured Investments and making judgments related to the levels, values, prices or any other affected variable under certain circumstances. Conflicts of interest may arise in connection with Barclays Bank PLC or its affiliates performing the role of calculation agent under the Structured Investment. If the Structured Investment were linked to one or more Barclays’ indices, Barclays Bank PLC is the index sponsor. The index sponsor is responsible for the composition, calculation and maintenance of the index and has the discretion in a number of circumstances to make judgments in connection with the composition, calculation and maintenance of the Index. The exercise of this discretion may present the index sponsor with significant conflicts of interest in light of the fact that Barclays Bank PLC is the issuer of the Structured Investments. The index sponsor has no obligation to take the needs of any buyer, seller or holder of the Structured Investments into consideration at any time. In addition, Barclays Bank PLC and its affiliates play a variety of roles in connection with the issuance of the Structured Investments, including hedging its obligations under the Structured Investments. In performing these duties, the economic interests of Barclays Bank PLC and its affiliates are potentially adverse to your interests as an investor in the Structured Investments. The Wealth and Investment Management division of Barclays may sell the Structured Investments to certain of its customers and may receive compensation from Barclays, as the issuer of the Structured Investments, in this capacity The Wealth and Investment Management division of Barclays may offer Structured Investments to its clients and be compensated for doing so. The Wealth and Investment Management division of Barclays, functioning in the United States through Barclays Capital Inc., will be acting as agent for Barclays Bank PLC in connection with the distribution of the Structured Investments to you and, as such, its role may create a potential conflict of interest. The Wealth and Investment Management division of Barclays is not acting as your agent or investment adviser, and is not representing you in any capacity with respect to any purchase of the Structured Investments by you. If you are considering whether to invest in the Structured Investments through the Wealth and Investment Management division of Barclays, Barclays Bank PLC strongly urges you to seek independent financial and investment advice to assess the merits of such investment. Commodities and commodities futures prices may change unpredictably Market prices of commodities futures contracts, including futures contracts underlying commodities indices, may fluctuate rapidly based on numerous factors, including: changes in supply and demand relationships (whether actual, perceived, anticipated, unanticipated or unrealized); weather; agriculture; trade, fiscal, monetary and exchange control programs; domestic and foreign political and economic events and policies; disease; pestilence; technological developments; changes in interest rates, whether through governmental action or market movements; and monetary and other governmental policies, action and inaction. The current or “spot” prices of physical commodities may also affect, in a volatile and inconsistent manner, the prices of futures contracts in respect of those physical commodities. These factors may adversely affect the level, value or price of commodities reference assets and, consequently, the market value and return, if any, of Structured Investments linked to commodities reference assets. Commodities futures and commodities indices that track commodities futures do not provide exposure to the spot prices of commodities Commodities futures prices, and the level or value of commodities indices that track commodities futures prices, reflect the prices for futures contracts for physical commodities. They do not reflect the current or “spot” prices of any commodity. A commodity futures contract represents an agreement to buy a set amount of an underlying physical commodity at a predetermined price during a stated delivery period, and the price of the contract reflects the expected value of the underlying physical commodity upon delivery in the future. In contrast, the underlying physical commodity’s current or spot price reflects the immediate delivery value of the commodity. A variety of factors can lead to a disparity between the expected future price of a commodity and the spot price at any given point in time, such as the cost of storing the commodity for the term of the futures contract, interest charges incurred to finance the purchase of the commodity, and expectations concerning supply and demand for the commodity. While price movements in futures contracts of physical commodities may at times correlate with changes in the spot prices of those commodities, such correlation may only be approximate or at times be weak. As such, Structured Investments that reference commodities futures contracts, or the level or value of commodities indices that track commodities futures contracts, are not intended to be representative of an investment that provides exposure to spot prices of commodities. Consequently, such Structured Investments may not be an effective means to hedge against the risk of losses in commodity-related transactions or to indirectly invest in commodities. 15 Barclays

FOR INSTITUTIONAL INVESTORS ONLY FOR INFORMATION ONLY NOT FOR FURTHER DISTRIBUTION Risk Factors The difference between commodities futures prices and the current prices of the underlying commodities may adversely affect the amounts payable under a Structured Investment linked to commodities indices Most commodity indices track the prices of commodities futures contracts. Unlike equities, which typically entitle the holder to a continuing stake in a corporation, commodities futures contracts normally specify a certain date for delivery of the underlying physical commodities. As the futures contracts underlying a commodities index approach expiration, they are replaced by, or “rolled” into, similar contracts that have a later expiration. If the market for these contracts is (putting aside other considerations) in “backwardation”, which means that the prices of futures contracts are lower in the distant delivery months than the spot price of the underlying commodity or the price of the futures contracts in the nearer delivery months, a positive “roll yield” would be reflected in the level of the commodities index. The actual realization of a potential roll yield will be dependent upon the level of the spot price of the physical commodity relative to the unwind price of the commodity futures contract at the time of sale of the contract. The absence of backwardation (or “contango”) in the commodity markets could result in negative “roll yields”, which could adversely affect the level or value of the commodities indices underlying your Structured Investment and, accordingly, decrease the payment you receive at maturity or upon redemption. Changes in law or regulation relating to commodities futures contracts may adversely affect the market value of, and the amounts payable under, your Structured Investment Commodity futures contracts that underlie commodities indices are subject to legal and regulatory regimes that are in the process of changing in the United States and, in some cases, in other countries. For example, the Dodd-Frank Wall Street Reform and Consumer Protection Act, commonly known as the “Dodd-Frank Act,” provides for substantial changes in the regulation of the futures and over-the-counter derivatives markets. While the Commodity Futures Trading Commission (the “CFTC”) has proposed and adopted many of the required regulations, the Dodd-Frank regulatory scheme has not yet been fully implemented (although certain requirements, including registration and reporting requirements, as well as centralized clearing requirements for certain products and market participants, are in effect) and the ultimate nature, scope and impact of the regulations on the markets and market participants cannot yet be determined. Many provisions of the legislation have not yet become effective, pending the effective date of such rules and, in some cases, the adoption of additional rules. Other regulatory organizations have proposed, and in the future may propose, further reforms similar to those enacted by the Dodd-Frank Act or other legislation which could have an adverse impact on the liquidity and depth of the commodities, futures and derivatives markets. Such legislation and reforms may reduce liquidity and increase market volatility in the commodities futures contracts that underlie commodities indices, which could adversely affect the prices of such contracts and, in turn, the market value of and the amounts payable on Structured Investments that reference commodities. 16 Barclays
