Executive Summary The Barclays Inverse US Treasury Composite ETN (“TAPR”) is linked to the performance of the Barclays Inverse US Treasury Futures Composite Index (“index”)– TAPR closing indicative note value (“CINV”) and index calculation is rules-based and formulaic – No tracking error, i.e. TAPR CINV tracks index return exactly between rebalance dates, before interest income, fees and costs On every rebalance date TAPR has -100% (face value) of short exposure, via the index, in each of the five US Treasury Futures Contracts– Monthly rebalancing1 is used instead of daily rebalancing to reduce negative convexity Investor fee of 0.43% p.a. approx and roll costs of 0.32% p.a. approx2 TAPR CINV reflects daily accrual of interest at the 4 week T-bill rate2TAPR can be purchased from or redeemed daily3 to the issuer at CINV – No bid/ask costs on closing orders of over 20,000 units. Listed on exchange to facilitate intra day liquidityInvesting in TAPR may not be suitable for all investors and involves significant risks, including:– ETNs are unsecured debt obligations of Barclays Bank PLC, are subject to the creditworthiness of the issuer, and are not guaranteed by any third party. Owning the ETNs is not equivalent to owning interests in the underlying index constituents. – ETNs are riskier than ordinary unsecured debt obligations, and an investor may lose some or all of their principal in the investment. ETNs are subject to a decrease in the level of the index, investor fees and other costs– TAPR may only be suitable for investors who intend to regularly monitor their investment to ensure that it remains consistent with their investment objectives Index Exposure Costs Interest Liquidity Risks 1. Additionally, the Index and TAPR will be rebalanced if the Index level has fallen by 65% or more since the last Index rebalance date.2. Slide 5 provides a concise summary of calculations w.r.t. the CINV calculations and of how the fees/costs are deducted from the ETN. 3. Subject to minimum size of 20,000 units and timing limitations as prescribed by prospectus.3 Investors should refer to the ETN prospectus for further details on the ETN and the Index and risks associated with an investment in the ETN.For Institutional Investors Only, Not For Distribution To Retail Customers Barclays

Index Methodology The Index tracks the sum of the returns of periodically rebalanced short positions in equal face values of the five U.S. Treasury futures contracts2 Year 5 Year 10 Year Long Bond Ultra-Long (“TU”) (“FV”) (“TY”) (“US”) (“WN”)Rebalanced every month1 to reset face value exposure to -100% in each of the futures contracts– Index rebalances on the fourth last business day of each month1Daily Index level is calculated as:Index Level at – Change in Futures Prices since Last RebalanceIndex Level = x 1 Sum ( )Last Rebalance Date 100Represents face value short Index level at last rebalance is adjusted by the sum of returns exposure in each futures contract since last rebalance in all the short futures contractsUnderlying futures “rolled” quarterly using calendar spreads2, shortly before the delivery monthClosing Index levels are calculated using CBOT closing mid settlement futures prices– Closing Index level is published on Bloomberg BXIIITAG <Index> page1. Additionally, the Index and TAPR will be rebalanced if the Index level has fallen by 65% or more since the last Index rebalance date.2. Index rolling mechanism uses the volume weighted average price of calendar spread futures contracts.4 Investors should refer to the ETN prospectus for further details on the ETN and the Index and risks associated with an investment in the ETN.For Institutional Investors Only, Not For Distribution To Retail Customers Barclays

The Daily Investor Fee for each ETN on the Inception Date was $0. On each subsequent calendar day until maturity or early redemption, the Daily Investor Fee for each ETN will equal (1.) the Closing Indicative Note Value on the immediately preceding calendar day times (2) 0.43% divided by (3) 365. The net effect of the investor fee accumulates over time and is subtracted at a rate of 0.43% per year. 2. On any calendar day that is not a roll date the index rolling cost for each ETN will equal $0. On any roll date, the index rolling cost for each ETN will equal 0.08% times the closing indicative note value on the immediately preceding index rebalance date. The index rolling cost will accrue on any roll date throughout the term of the ETNs, resulting in a cumulative fee rate of approximately 0.32% per year.5 Investors should refer to the ETN prospectus for further details on the ETN and the Index and risks associated with an investment in the ETN.For Institutional Investors Only, Not For Distribution To Retail Customers Barclays

Selected Risk Considerations (1/2)An investment in the Barclays ETNs described herein (the “ETNs”) involves risks. Selected risks are summarized here, but we urge you to read the more detailed explanation of risks described under “Risk Factors” in the applicable prospectus supplement and pricing supplement.You May Lose Some or All of Your Principal: The ETNs are exposed to any decrease in the level of the underlying index between the inception date and the applicable valuation date. Based on historical and hypothetical historical data, the level of the index has decreased significantly over time in the past and may continue to decrease significantly over the term of the ETNs. Additionally, if the level of the underlying index is insufficient to offset the negative effect of the daily investor fee and the index rolling cost, you will lose some or all of your investment at maturity or upon redemption, even if the value of such index has increased. Because the ETNs are subject to a daily investor fee and index rolling cost, the return on the ETNs will always be lower than the total return on a direct investment in the index components. The ETNs are riskier than ordinary unsecured debt securities and have no principal protection.Credit of Barclays Bank PLC: The ETNs are senior unsecured debt obligations of the issuer, Barclays Bank PLC, and are not, either directly or indirectly, an obligation of any third party. Any payment to be made on the ETNs depends on the ability of Barclays Bank PLC to satisfy its obligations as they come due and are not guaranteed by a third party. As a result, the actual and perceived creditworthiness of Barclays Bank PLC may affect the market value of the ETNs and, in the event Barclays Bank PLC were to default on its obligations, you may not receive the amounts owed to you under the terms of the ETNs.Issuer Redemption: Barclays Bank PLC has the right to redeem or “call” the ETNs (in whole but not in part) at our sole discretion without your consent on any business day on or after the inception date until and including maturity.Changes in the Prices of U.S. Treasury Futures Contracts May Affect the Value of Your ETNs: The return on your ETNs is linked to the performance of the underlying index, which corresponds to changes in the prices of the U.S. Treasury future contracts included in the index, and therefore such prices may y affect ffect the amount mount payable yable on your our ETNs TNs at maturity aturity or upon pon early arly redemption and and the market value of your our ETNs TNs.The Index Is Subject to Risks Associated with Synthetic Short Positions in U.S. Treasury Futures Contracts: Because short positions are subject to unlimited risk of loss because there is no limit on the appreciation of the price of the relevant asset before the short position is closed. One or more of the U.S. Treasury futures contracts to which the Index provides synthetic short exposure may appreciate substantially, which would have an adverse effect on the level of the Index and, accordingly, decrease the payment you receive at maturity or upon early redemption.Market and Volatility Risk: The market value of the ETNs may be influenced by many unpredictable factors and may fluctuate between the date you purchase them and the maturity date or redemption date. You may also sustain a significant loss if you sell your ETNs in the secondary market. Factors that may influence the market value of the ETNs include prevailing market prices of the U.S. stock or U.S. Treasury markets, the index components included in the underlying index, and prevailing market prices of options on such index or any other financial instruments related to such index; and supply and demand for the ETNs, including economic, financial, political, regulatory, geographical or judicial events that affect the level of such index or other financial instruments related to such index.A Trading Market for the ETNs May Not Develop: Although the ETNs are listed on NASDAQ, a trading market for the ETNs may not exist at any time. Even if there is a secondary market for the ETNs, , whether as a result of any listing of the ETNs or on an over-the-counter basis, it may not provide enough liquidity for you to trade or sell your ETNs easily, as we are not required to maintain any listing of the ETNs.10 Investors should refer to the ETN prospectus for further details on the ETN and the Index and risks associated with an investment in the ETN.For Institutional Investors Only, Not For Distribution To Retail Customers Barclays

Selected Risk Considerations (2/2)No Interest Payments from the ETNs: You will not receive any periodic interest payments on your ETNs.Restrictions on the Minimum Number of ETNs and Date Restrictions for Redemptions: You must redeem at least 20,000 ETNs at one time in order to exercise your right to redeem your ETNs on any redemption date. If you hold fewer than 20,000 ETNs or fewer than 20,000 ETNs are outstanding, you will not be able to exercise your right to redeem your ETNs. .You may only redeem your ETNs on a redemption date if we receive a notice of redemption from you by certain dates and times as set forth in the pricing supplement. Uncertain Tax Treatment: Significant aspects of the tax treatment of the ETNs are uncertain. You should consult your own tax advisor about your own tax situation.Barclays Bank PLC has filed a registration statement (including a prospectus) with the SEC for the offering to which this communication relates.
