CONSENT TO U.K. BAIL-IN POWER

Notwithstanding any other agreements, arrangements or understandings between us and any holder or beneficial owner of the Notes, by acquiring the Notes, each holder and beneficial owner of the Notes acknowledges, accepts, agrees to be bound by, and consents to the exercise of, any U.K. Bail-in Power by the relevant U.K. resolution authority.

Under the U.K. Banking Act 2009, as amended, the relevant U.K. resolution authority may exercise a U.K. Bail-in Power in circumstances in which the relevant U.K. resolution authority is satisfied that the resolution conditions are met. These conditions include that a U.K. bank or investment firm is failing or is likely to fail to satisfy the Financial Services and Markets Act 2000 (the “FSMA”) threshold conditions for authorization to carry on certain regulated activities (within the meaning of section 55B FSMA) or, in the case of a U.K. banking group company that is a European Economic Area (“EEA”) or third country institution or investment firm, that the relevant EEA or third country relevant authority is satisfied that the resolution conditions are met in respect of that entity.

The U.K. Bail-in Power includes any write-down, conversion, transfer, modification and/or suspension power, which allows for (i) the reduction or cancellation of all, or a portion, of the principal amount of, interest on, or any other amounts payable on, the Notes; (ii) the conversion of all, or a portion, of the principal amount of, interest on, or any other amounts payable on, the Notes into shares or other securities or other obligations of Barclays Bank PLC or another person (and the issue to, or conferral on, the holder or beneficial owner of the Notes such shares, securities or obligations); and/or (iii) the amendment or alteration of the maturity of the Notes, or amendment of the amount of interest or any other amounts due on the Notes, or the dates on which interest or any other amounts become payable, including by suspending payment for a temporary period; which U.K. Bail-in Power may be exercised by means of a variation of the terms of the Notes solely to give effect to the exercise by the relevant U.K. resolution authority of such U.K. Bail-in Power. Each holder and beneficial owner of the Notes further acknowledges and agrees that the rights of the holders or beneficial owners of the Notes are subject to, and will be varied, if necessary, solely to give effect to, the exercise of any U.K. Bail-in Power by the relevant U.K. resolution authority. For the avoidance of doubt, this consent and acknowledgment is not a waiver of any rights holders or beneficial owners of the Notes may have at law if and to the extent that any U.K. Bail-in Power is exercised by the relevant U.K. resolution authority in breach of laws applicable in England.

For more information, please see “Selected Risk Considerations—You May Lose Some or All of Your Investment If Any U.K. Bail-in Power Is Exercised by the Relevant U.K. Resolution Authority” in this pricing supplement as well as “U.K. Bail-in Power,” “Risk Factors—Risks Relating to the Securities Generally—Regulatory action in the event a bank or investment firm in the Group is failing or likely to fail could materially adversely affect the value of the securities” and “Risk Factors—Risks Relating to the Securities Generally—Under the terms of the securities, you have agreed to be bound by the exercise of any U.K. Bail-in Power by the relevant U.K. resolution authority” in the accompanying prospectus supplement.

PS-2

ADDITIONAL INFORMATION REGARDING OUR ESTIMATED VALUE OF THE NOTES

Our internal pricing models take into account a number of variables and are based on a number of subjective assumptions, which may or may not materialize, typically including volatility, interest rates, and our internal funding rates. Our internal funding rates (which are our internally published borrowing rates based on variables such as market benchmarks, our appetite for borrowing, and our existing obligations coming to maturity) may vary from the levels at which our benchmark debt securities trade in the secondary market. Our estimated value on the Initial Valuation Date is based on our internal funding rates. Our estimated value of the Notes may be lower if such valuation were based on the levels at which our benchmark debt securities trade in the secondary market.

Our estimated value of the Notes on the Initial Valuation Date is less than the initial issue price of the Notes. The difference between the initial issue price of the Notes and our estimated value of the Notes results from several factors, including any sales commissions to be paid to Barclays Capital Inc. or another affiliate of ours, any selling concessions, discounts, commissions or fees to be allowed or paid to non-affiliated intermediaries, the estimated profit that we or any of our affiliates expect to earn in connection with structuring the Notes, the estimated cost which we may incur in hedging our obligations under the Notes, and estimated development and other costs which we may incur in connection with the Notes.

Our estimated value on the Initial Valuation Date is not a prediction of the price at which the Notes may trade in the secondary market, nor will it be the price at which Barclays Capital Inc. may buy or sell the Notes in the secondary market. Subject to normal market and funding conditions, Barclays Capital Inc. or another affiliate of ours intends to offer to purchase the Notes in the secondary market but it is not obligated to do so.

Assuming that all relevant factors remain constant after the Initial Valuation Date, the price at which Barclays Capital Inc. may initially buy or sell the Notes in the secondary market, if any, and the value that we may initially use for customer account statements, if we provide any customer account statements at all, may exceed our estimated value on the Initial Valuation Date for a temporary period expected to be approximately six months after the Issue Date because, in our discretion, we may elect to effectively reimburse to investors a portion of the estimated cost of hedging our obligations under the Notes and other costs in connection with the Notes which we will no longer expect to incur over the term of the Notes. We made such discretionary election and determined this temporary reimbursement period on the basis of a number of factors, which may include the tenor of the Notes and/or any agreement we may have with the distributors of the Notes. The amount of our estimated costs which we effectively reimburse to investors in this way may not be allocated ratably throughout the reimbursement period, and we may discontinue such reimbursement at any time or revise the duration of the reimbursement period after the initial Issue Date of the Notes based on changes in market conditions and other factors that cannot be predicted.

We urge you to read the “Selected Risk Considerations” beginning on page PS–8 of this pricing supplement.

·You seek an investment that provides for the full repayment of principal at maturity.

·You anticipate that the Reference Asset Return of the Least Performing Reference Asset will be less than 0.00%, and/or you are unwilling or unable to accept the risk that, if it is, you may lose up to 5.00% of the principal amount of your Notes.

·You are unwilling or unable to accept the risk that the negative performance of only one Reference Asset may cause you to earn no positive return or to suffer a loss of principal at maturity, regardless of the performance of the other Reference Asset.

·You seek an investment for which there will be an active secondary market, and/or you are unwilling or unable to hold the Notes to maturity.

·You prefer the lower risk, and therefore accept the potentially lower returns, of fixed income investments with comparable maturities and credit ratings.

·You are unwilling or unable to assume our credit risk for all payments on the Notes.

·You are unwilling or unable to consent to the exercise of any U.K. Bail-in Power by any relevant U.K. resolution authority.

Neither the Issuer nor Barclays Capital Inc. makes any recommendation as to the suitability of the Notes for investment.

HYPOTHETICAL EXAMPLES OF AMOUNTS PAYABLE AT MATURITY

The following examples demonstrate the hypothetical payment at maturity under various circumstances. The “total return” as used in these examples is the number, expressed as a percentage, that results from comparing the payment at maturity per $1,000 principal amount Note to $1,000. The examples set forth below are purely hypothetical and are provided for illustrative purposes only and may not be the actual total returns applicable to a purchaser of the Notes. The numbers appearing in the following table and examples have been rounded for ease of analysis. The hypothetical examples below do not take into account any tax consequences from investing in the Notes and make the following key assumption:

§Hypothetical Initial Value of each Reference Asset: 100.00*

*The hypothetical Initial Value of 100.00 for each Reference Asset have been chosen for illustrative purposes only. The actual Initial Value for each Reference Asset is as set forth on the cover of this pricing supplement.

**  per $1,000 principal amount Note

The following examples illustrate how the payments at maturity set forth in the table above are calculated:

Example 1: The Final Value of the S&P 500 Index is 140.00, the Final Value of DJIA is 110.00 and the Final Value of the Nasdaq-100 Index is 120.00.

Because the DJIA Index has the lowest Reference Asset Return, the DJIA Index is the Least Performing Reference Asset. Because the Reference Asset Return of the Least Performing Reference Asset is greater than or equal to 0.00%, you will receive a payment at maturity of $1,135.00 per $1,000 principal amount Note that you hold, calculated as follows:

$1,000 + [$1,000 × Reference Asset Return of the Least Performing Reference Asset × Upside Leverage Factor]

$1,000 + [$1,000 × 10.00% × 1.35] = $1,135.00

The total return on investment of the Notes is 13.50%.

Example 2: The Final Value of the S&P 500 Index is 105.00, the Final Value of DJIA is 110.00 and the Final Value of the Nasdaq-100 Index is 97.50.

Because the Nasdaq-100 Index has the lowest Reference Asset Return, the Nasdaq-100 Index is the Least Performing Reference Asset. Because the Reference Asset Return of the Least Performing Reference Asset is less than 0.00% but is greater than -5.00%, you will receive a payment at maturity of $975.00 per $1,000 principal amount Note that you hold, calculated as follows:

$1,000 + [$1,000 × Reference Asset Return of the Least Performing Reference Asset]

$1,000 + [$1,000 × -2.50%] = $975.00

The total return on investment of the Notes is -2.50%.

PS-6

Example 3: The Final Value of the S&P 500 Index is 80.00, the Final Value of the DJIA Index is 90.00 and the Final Value of the Russell 2000 Index is 120.00.

Because the S&P 500 Index has the lowest Reference Asset Return, the S&P 500 Index is the Least Performing Reference Asset. Because the Final Value of the Least Performing Reference Asset is less than or equal to -5.00%, you will receive a payment at maturity of $950.00 per $1,000 principal amount Note that you hold, which is the Minimum Payment and Maturity.

The total return on investment of the Notes is -5.00%, which reflects the Minimum Payment at Maturity.

Example 4: The Final Value of the S&P 500 Index is 40.00, the Final Value of DJIA is 100.00 and the Final Value of the Nasdaq-100 Index is 30.00.

Because the Nasdaq-100 Index has the lowest Reference Asset Return, the Nasdaq-100 Index is the Least Performing Reference Asset. Because the Final Value of the Least Performing Reference Asset is less than or equal to -5.00%, you will receive a payment at maturity of $950.00 per $1,000 principal amount Note that you hold, which is the Minimum Payment at Maturity.

The total return on investment of the Notes is -5.00%, which reflects the Minimum Payment at Maturity.

PS-7

SELECTED RISK CONSIDERATIONS

An investment in the Notes involves significant risks. Investing in the Notes is not equivalent to investing directly in the Reference Assets or their components. Some of the risks that apply to an investment in the Notes are summarized below, but we urge you to read the more detailed explanation of risks relating to the Notes generally in the “Risk Factors” section of the prospectus supplement. You should not purchase the Notes unless you understand and can bear the risks of investing in the Notes.

·You May Lose up to 5.00% of the Principal Amount of Your Notes—The Notes differ from ordinary debt securities in that the Issuer will not necessarily repay the full principal amount of the Notes at maturity. If the Reference Asset Return of the Least Performing Reference Asset is less than 0.00%, you will lose 1.00% of the principal amount of your Notes for every 1.00% that the Reference Asset Return of the Least Performing Reference Asset falls below 0.00%, subject to the Minimum Payment at Maturity of $950.00 per $1,000 principal amount Note. You may lose up to 5.00% of the principal amount of your Notes.

·You Are Exposed to the Market Risk of Each Reference Asset—Your return on the Notes is not linked to a basket consisting of the Reference Assets. Rather, it will be contingent upon the independent performance of each Reference Asset. Unlike an instrument with a return linked to a basket of underlying assets in which risk is mitigated and diversified among all the components of the basket, you will be exposed to the risks related to each Reference Asset. Poor performance by any Reference Asset over the term of the Notes may negatively affect your return and will not be offset or mitigated by any increases or lesser declines in the value of any other Reference Asset. To receive a positive return on your Notes at maturity, the Final Value of each Reference Asset must be greater than 0.00%. Accordingly, your investment is subject to the market risk of each Reference Asset.

·You Will Not Receive More than the Principal Amount of Your Notes at Maturity Unless the Reference Asset Return of Each Reference Asset is Greater Than 0.00%; Your Payment at Maturity Will be Calculated Solely Based Upon the Reference Asset Return of the Least Performing Reference Asset—The payment at maturity will not exceed the principal amount of your Notes unless the Reference Asset Return of each Reference Asset is greater than 0.00%. Even if the Reference Asset Return of each Reference Asset is greater than 0.00%, the payment at maturity will nonetheless be calculated solely based upon the Reference Asset Return of the Least Performing Reference Asset. You will not participate in any appreciation of any other Reference Asset being higher than the Reference Asset Return of the Least Performing Reference Asset, which may be significant.

Similarly, if each Reference Asset has a Reference Asset Return less than 0.00% Reference Asset Return, any payment at maturity will depend solely on the Reference Asset Return of the Least Performing Reference Asset.

·The Payment at Maturity of Your Notes is Based Solely on the Closing Value of the Least Performing Reference Asset on the Final Valuation Date—The Final Values (and resulting Reference Asset Returns) will be based solely on the Closing Values of the Reference Assets on the Final Valuation Date. Accordingly, if the value of the Least Performing Reference Asset drops on the Final Valuation Date, the payment at maturity on the Notes may be significantly less than it would have been had it been linked to the value of such Reference Asset at any time prior to such drop.

·Credit of Issuer—The Notes are unsecured and unsubordinated 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 Notes, including any repayment of principal, is subject to the ability of Barclays Bank PLC to satisfy its obligations as they come due and is not guaranteed by any third party. As a result, the actual and perceived creditworthiness of Barclays Bank PLC may affect the market value of the Notes, and in the event Barclays Bank PLC were to default on its obligations, you may not receive any amounts owed to you under the terms of the Notes.

·You May Lose Some or All of Your Investment If Any U.K. Bail-in Power Is Exercised by the Relevant U.K. Resolution Authority—Notwithstanding any other agreements, arrangements or understandings between Barclays Bank PLC and any holder or beneficial owner of the Notes, by acquiring the Notes, each holder and beneficial owner of the Notes acknowledges, accepts, agrees to be bound by, and consents to the exercise of, any U.K. Bail-in Power by the relevant U.K. resolution authority as set forth under “Consent to U.K. Bail-in Power” in this pricing supplement. Accordingly, any U.K. Bail-in Power may be exercised in such a manner as to result in you and other holders and beneficial owners of the Notes losing all or a part of the value of your investment in the Notes or receiving a different security from the Notes, which may be worth significantly less than the Notes and which may have significantly fewer protections than those typically afforded to debt securities. Moreover, the relevant U.K. resolution authority may exercise the U.K. Bail-in Power without providing any advance notice to, or requiring the consent of, the holders and the beneficial owners of the Notes. The exercise of any U.K. Bail-in Power by the relevant U.K. resolution authority with respect to the Notes will not be a default or an Event of Default (as each term is defined in the senior debt securities indenture) and the trustee will not be liable for any action that the trustee takes, or abstains from taking, in either case, in accordance with the exercise of the U.K. Bail-in Power by the relevant U.K. resolution authority with respect to the Notes. See “Consent to U.K. Bail-in Power” in this pricing supplement as well as “U.K. Bail-in Power,” “Risk Factors—Risks Relating to the Securities Generally—Regulatory action in the event a bank or investment firm in the Group is failing or likely to fail could materially adversely affect the value of the securities” and “Risk Factors—Risks Relating to the Securities Generally—Under the terms of the securities, you have agreed to be bound by the exercise of any U.K. Bail-in Power by the relevant U.K. resolution authority” in the accompanying prospectus supplement.

·Owning the Notes is Not the Same as Owning Any Reference Asset or Any Securities to which Any Reference Asset Provides Exposure—The return on the Notes may not reflect the return you would realize if you actually owned any Reference Asset or any securities to which any Reference Asset provides exposure. As a holder of the Notes, you will not have voting rights or rights to receive dividends or other distributions or any other rights that holders of any Reference Asset or any securities to which any Reference Asset provides exposure may have.

PS-8

·Each Reference Asset Reflects the Price Return of the Securities Composing that Reference Asset, Not the Total Return—The return on the Notes is based on the performance of the Reference Assets, which reflect changes in the market prices of the securities composing each Reference Asset. Each Reference Asset is not a “total return” index that, in addition to reflecting those price returns, would also reflect dividends paid on the securities composing the applicable Reference Asset. Accordingly, the return on the Notes will not include such a total return feature.

·Adjustments to Any Reference Asset Could Adversely Affect the Value of the Notes—The sponsor of any Reference Asset may add, delete, substitute or adjust the securities composing that Reference Asset or make other methodological changes to that Reference Asset that could affect their value. The Calculation Agent will calculate the value to be used as the Closing Value of that Reference Asset in the event of certain material changes in or modifications to that Reference Asset. In addition, the sponsor of any Reference Asset may also discontinue or suspend calculation or publication of that Reference Asset at any time. Under these circumstances, the Calculation Agent may select a successor index that the Calculation Agent determines to be comparable to any Reference Asset or, if no successor index is available, the Calculation Agent will determine the value to be used as the Closing Value of that Reference Asset. Any of these actions could adversely affect the value of the Reference Assets and, consequently, the value of the Notes. See “Reference Assets—Indices—Adjustments Relating to Securities with an Index as a Reference Asset” in the accompanying prospectus supplement.

·Historical Performance of the Reference Assets Should Not Be Taken as Any Indication of the Future Performance of the Reference Assets Over the Term of the Notes—The value of each Reference Asset has fluctuated in the past and may, in the future, experience significant fluctuations. The historical performance of a Reference Asset is not an indication of the future performance of that Reference Asset over the term of the Notes. The historical correlation between the Reference Assets is not an indication of the future correlation between them over the term of the Notes. Therefore, the performance of the Reference Assets individually or in comparison to each other over the term of the Notes may bear no relation or resemblance to the historical performance of the Reference Assets.

·The Notes Are Subject to Risks Associated with Non-U.S. Securities Markets—Certain component securities of the Nasdaq-100 Index are issued by non-U.S. companies in non-U.S. securities markets. Investments in securities linked to the value of such non-U.S. equity securities, such as the Notes, involve risks associated with the securities markets in the home countries of the issuers of those non-U.S. equity securities, including risks of volatility in those markets, governmental intervention in those markets and cross shareholdings in companies in certain countries. Also, there is generally less publicly available information about companies in some of these jurisdictions than there is about U.S. companies that are subject to the reporting requirements of the SEC, and generally non-U.S. companies are subject to accounting, auditing and financial reporting standards and requirements and securities trading rules different from those applicable to U.S. reporting companies. The prices of securities in non-U.S. markets may be affected by political, economic, financial and social factors in those countries, or global regions, including changes in government, economic and fiscal policies and currency exchange laws.

·The Estimated Value of Your Notes is Lower Than the Initial Issue Price of Your Notes—The estimated value of your Notes on the Initial Valuation Date is lower than the initial issue price of your Notes. The difference between the initial issue price of your Notes and the estimated value of the Notes is a result of certain factors, such as any sales commissions to be paid to Barclays Capital Inc. or another affiliate of ours, any selling concessions, discounts, commissions or fees to be allowed or paid to non-affiliated intermediaries, the estimated profit that we or any of our affiliates expect to earn in connection with structuring the Notes, the estimated cost which we may incur in hedging our obligations under the Notes, and estimated development and other costs which we may incur in connection with the Notes.

·The Estimated Value of Your Notes Might be Lower if Such Estimated Value Were Based on the Levels at Which Our Debt Securities Trade in the Secondary Market—The estimated value of your Notes on the Initial Valuation Date is based on a number of variables, including our internal funding rates. Our internal funding rates may vary from the levels at which our benchmark debt securities trade in the secondary market. As a result of this difference, the estimated value referenced above might be lower if such estimated value was based on the levels at which our benchmark debt securities trade in the secondary market.

·The Estimated Value of the Notes is Based on Our Internal Pricing Models, Which May Prove to be Inaccurate and May be Different from the Pricing Models of Other Financial Institutions—The estimated value of your Notes on the Initial Valuation Date is based on our internal pricing models, which take into account a number of variables and are based on a number of subjective assumptions, which may or may not materialize. These variables and assumptions are not evaluated or verified on an independent basis. Further, our pricing models may be different from other financial institutions’ pricing models and the methodologies used by us to estimate the value of the Notes may not be consistent with those of other financial institutions which may be purchasers or sellers of Notes in the secondary market. As a result, the secondary market price of your Notes may be materially different from the estimated value of the Notes determined by reference to our internal pricing models.

PS-9

·The Estimated Value of Your Notes Is Not a Prediction of the Prices at Which You May Sell Your Notes in the Secondary Market, if any, and Such Secondary Market Prices, If Any, Will Likely be Lower Than the Initial Issue Price of Your Notes and May be Lower Than the Estimated Value of Your Notes—The estimated value of the Notes will not be a prediction of the prices at which Barclays Capital Inc., other affiliates of ours or third parties may be willing to purchase the Notes from you in secondary market transactions (if they are willing to purchase, which they are not obligated to do). The price at which you may be able to sell your Notes in the secondary market at any time will be influenced by many factors that cannot be predicted, such as market conditions, and any bid and ask spread for similar sized trades, and may be substantially less than our estimated value of the Notes. Further, as secondary market prices of your Notes take into account the levels at which our debt securities trade in the secondary market, and do not take into account our various costs related to the Notes such as fees, commissions, discounts, and the costs of hedging our obligations under the Notes, secondary market prices of your Notes will likely be lower than the initial issue price of your Notes. As a result, the price at which Barclays Capital Inc., other affiliates of ours or third parties may be willing to purchase the Notes from you in secondary market transactions, if any, will likely be lower than the price you paid for your Notes, and any sale prior to the Maturity Date could result in a substantial loss to you.

·The Temporary Price at Which We May Initially Buy The Notes in the Secondary Market And the Value We May Initially Use for Customer Account Statements, If We Provide Any Customer Account Statements At All, May Not Be Indicative of Future Prices of Your Notes—Assuming that all relevant factors remain constant after the Initial Valuation Date, the price at which Barclays Capital Inc. may initially buy or sell the Notes in the secondary market (if Barclays Capital Inc. makes a market in the Notes, which it is not obligated to do) and the value that we may initially use for customer account statements, if we provide any customer account statements at all, may exceed our estimated value of the Notes on the Initial Valuation Date, as well as the secondary market value of the Notes, for a temporary period after the initial Issue Date of the Notes. The price at which Barclays Capital Inc. may initially buy or sell the Notes in the secondary market and the value that we may initially use for customer account statements may not be indicative of future prices of your Notes.

·We and Our Affiliates May Engage in Various Activities or Make Determinations That Could Materially Affect the Notes in Various Ways and Create Conflicts of Interest—We and our affiliates play a variety of roles in connection with the issuance of the Notes, as described below. In performing these roles, our and our affiliates’ economic interests are potentially adverse to your interests as an investor in the Notes.

In connection with our normal business activities and in connection with hedging our obligations under the Notes, we and our affiliates make markets in and trade various financial instruments or products for our accounts and for the account of our clients and otherwise provide investment banking and other financial services with respect to these financial instruments and products. These financial instruments and products may include securities, derivative instruments or assets that may relate to the Reference Assets or their components. In any such market making, trading and hedging activity, and other financial services, we or our affiliates may take positions or take actions that are inconsistent with, or adverse to, the investment objectives of the holders of the Notes. We and our affiliates have no obligation to take the needs of any buyer, seller or holder of the Notes into account in conducting these activities. Such market making, trading and hedging activity, investment banking and other financial services may negatively impact the value of the Notes.

In addition, the role played by Barclays Capital Inc., as the agent for the Notes, could present significant conflicts of interest with the role of Barclays Bank PLC, as issuer of the Notes. For example, Barclays Capital Inc. or its representatives may derive compensation or financial benefit from the distribution of the Notes and such compensation or financial benefit may serve as incentive to sell the Notes instead of other investments. Furthermore, we and our affiliates establish the offering price of the Notes for initial sale to the public, and the offering price is not based upon any independent verification or valuation.

In addition to the activities described above, we will also act as the Calculation Agent for the Notes. As Calculation Agent, we will determine any values of the Reference Assets and make any other determinations necessary to calculate any payments on the Notes. In making these determinations, the Calculation Agent may be required to make discretionary judgements relating to the Reference Assets, including determining whether a market disruption event has occurred or whether certain adjustments to the Reference Assets or other terms of the Notes are necessary, as further described in the accompanying prospectus supplement. In making these discretionary judgments, our economic interests are potentially adverse to your interests as an investor in the Notes, and any of these determinations may adversely affect any payments on the Notes.

·Lack of Liquidity—The Notes will not be listed on any securities exchange. Barclays Capital Inc. and other affiliates of Barclays Bank PLC intend to make a secondary market for the Notes but are not required to do so, and may discontinue any such secondary market making at any time, without notice. Barclays Capital Inc. may at any time hold unsold inventory, which may inhibit the development of a secondary market for the Notes. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the Notes easily. Because other dealers are not likely to make a secondary market for the Notes, the price at which you may be able to trade your Notes is likely to depend on the price, if any, at which Barclays Capital Inc. and other affiliates of Barclays Bank PLC are willing to buy the Notes. The Notes are not designed to be short-term trading instruments. Accordingly, you should be able and willing to hold your Notes to maturity.

·Tax Treatment—As discussed further below under “Tax Considerations” and in the accompanying prospectus supplement, if you are a U.S. individual or taxable entity, you should be required to accrue interest on a current basis in respect of the Notes over their term based on the comparable yield for the Notes and pay tax accordingly, even though you will not receive any payments from us until maturity. This comparable yield is determined solely to calculate the amount on which you will be taxed prior to maturity and is neither a prediction nor a guarantee of what the actual yield will be.

PS-10

·Many Economic and Market Factors Will Impact the Value of the Notes—The value of the Notes will be affected by a number of economic and market factors that interact in complex and unpredictable ways and that may either offset or magnify each other, including:

othe market prices of, dividend rate on and the expected volatility of the Reference Assets and the components of each Reference Asset;

ocorrelation (or lack of correlation) of the Reference Assets;

othe time to maturity of the Notes;

ointerest and yield rates in the market generally;

oa variety of economic, financial, political, regulatory or judicial events;

osupply and demand for the Notes; and

oour creditworthiness, including actual or anticipated downgrades in our credit ratings.

TAX CONSIDERATIONS

You should review carefully the sections entitled “Material U.S. Federal Income Tax Consequences—Tax Consequences to U.S. Holders—Notes Treated as Indebtedness for U.S. Federal Income Tax Purposes” and, if you are a non-U.S. holder, “—Tax Consequences to Non-U.S. Holders,” in the accompanying prospectus supplement. The discussion below applies to you only if you are an initial purchaser of the Notes; if you are a secondary purchaser of the Notes, the tax consequences to you may be different. Notwithstanding that the Notes do not provide for the full repayment of their principal amount at or prior to maturity, in the opinion of our special tax counsel, Davis Polk & Wardwell LLP, the Notes should be treated as debt instruments for U.S. federal income tax purposes. The remainder of this discussion assumes that this treatment is correct.

Assuming the treatment described above is correct, in the opinion of our special tax counsel, the Notes will be treated as “contingent payment debt instruments” for U.S. federal income tax purposes, as described under “—Contingent Payment Debt Instruments” in the accompanying prospectus supplement. The remainder of this discussion assumes that this treatment is correct.

Regardless of your method of accounting for U.S. federal income tax purposes, you generally will be required to accrue taxable interest income in each year on a constant yield to maturity basis at the “comparable yield,” as determined by us, even though we will not be required to make any payment with respect to the Notes prior to maturity. Upon a sale or exchange (including redemption at maturity), you generally will recognize taxable income or loss equal to the difference between the amount received from the sale or exchange and your adjusted tax basis in the Notes. You generally must treat any income as interest income and any loss as ordinary loss to the extent of previous interest inclusions, and the balance as capital loss. The deductibility of capital losses is subject to limitations.

The discussions herein and in the accompanying prospectus supplement do not address the consequences to taxpayers subject to special tax accounting rules under Section 451(b).

After the original issue date, you may obtain the comparable yield and the projected payment schedule by requesting them from Barclays Cross Asset Sales Americas, at (212) 528-7198. Neither the comparable yield nor the projected payment schedule constitutes a representation by us regarding the actual amount that we will pay on the Notes.

You should consult your tax advisor regarding the U.S. federal tax consequences of an investment in the Notes, as well as tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

Non-U.S. Holders. We do not believe that non-U.S. holders should be required to provide a Form W-8 in order to avoid 30% U.S. withholding tax with respect to the excess (if any) of the Payment at Maturity over the face amount of the Notes, although the Internal Revenue Service (the “IRS”) could challenge this position. However, non-U.S. holders should in any event expect to be required to provide appropriate Forms W-8 or other documentation in order to establish an exemption from backup withholding, as described under the heading “—Information Reporting and Backup Withholding” in the accompanying prospectus supplement. If any withholding is required, we will not be required to pay any additional amounts with respect to amounts withheld.

Treasury regulations under Section 871(m) generally impose a withholding tax on certain “dividend equivalents” under certain “equity linked instruments.” A recent IRS notice excludes from the scope of Section 871(m) instruments issued prior to January 1, 2021 that do not have a “delta of one” with respect to underlying securities that could pay U.S.-source dividends for U.S. federal income tax purposes (each an “Underlying Security”). Based on our determination that the Notes do not have a “delta of one” within the meaning of the regulations, our special tax counsel is of the opinion that these regulations should not apply to the Notes with regard to non-U.S. holders. Our determination is not binding on the IRS, and the IRS may disagree with this determination. Section 871(m) is complex and its application may depend on your particular circumstances, including whether you enter into other transactions with respect to an Underlying Security. You should consult your tax advisor regarding the potential application of Section 871(m) to the Notes.

SUPPLEMENTAL PLAN OF DISTRIBUTION

We have agreed to sell to Barclays Capital Inc. (the “Agent”), and the Agent has agreed to purchase from us, the principal amount of the Notes, and at the price, specified on the cover of this pricing supplement. The Agent commits to take and pay for all of the Notes, if any are taken.

VALIDITY OF THE NOTES

In the opinion of Davis Polk & Wardwell LLP, as special United States products counsel to Barclays Bank PLC, when the Notes offered by this pricing supplement have been executed and issued by Barclays Bank PLC and authenticated by the trustee pursuant to the indenture, and delivered against payment as contemplated herein, such Notes will be valid and binding obligations of Barclays Bank PLC, enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally, concepts of reasonableness and equitable principles of general applicability (including, without limitation, concepts of good faith, fair dealing and the lack of bad faith) and possible judicial or regulatory actions giving effect to governmental actions or foreign laws affecting creditors’ rights, provided that such counsel expresses no opinion as to the effect of fraudulent conveyance, fraudulent transfer or similar provision of applicable law on the conclusions expressed above. This opinion is given as of the date hereof and is limited to the laws of the State of New York. Insofar as this opinion involves matters governed by English law, Davis Polk & Wardwell LLP has relied, with Barclays Bank PLC’s permission, on the opinion of Davis Polk & Wardwell London LLP, dated as of June 14, 2019, filed as an exhibit to a report on Form 6-K by Barclays Bank PLC on June 14, 2019, and this opinion is subject to the same assumptions, qualifications and limitations as set forth in such opinion of Davis Polk & Wardwell London LLP. In addition, this opinion is subject to customary assumptions about the trustee’s authorization, execution and delivery of the indenture and its authentication of the Notes and the validity, binding nature and enforceability of the indenture with respect to the trustee, all as stated in the letter of Davis Polk & Wardwell LLP, dated June 14, 2019, which has been filed as an exhibit to the report on Form 6-K referred to above.
