CONSENT TO U.K. BAIL-IN POWER

Notwithstanding and to the exclusion of any other term of the Notes or any other agreements, arrangements or understandings between us and any holder or beneficial owner of the Notes (or the Trustee on behalf of the holders 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); (iii) the cancellation of the Notes and/or (iv) 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-Risks Relating to the Issuer-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, including the exercise by the relevant U.K. resolution authority of a variety of statutory resolution powers, could materially adversely affect the value of any 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.

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 is a result of 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 (including any structuring or other distribution related 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-12 of this pricing supplement.

ADDITIONAL TERMS OF THE NOTES

The Observation Dates (including the Final Valuation Date), the Contingent Coupon Payment Dates, any Call Settlement Date and the Maturity Date are subject to postponement in certain circumstances, as described under "Reference Assets-Equity Securities-Market Disruption Events for Securities with an Equity Security as a Reference Asset," "Reference Assets-Least or Best Performing Reference Asset-Scheduled Trading Days and Market Disruption Events for Securities Linked to the Reference Asset with the Lowest or Highest Return in a Group of Two or More Equity Securities, Exchange-Traded Funds and/or Indices of Equity Securities" and "Terms of the Notes-Payment Dates" in the accompanying prospectus supplement.

In addition, the Reference Assets and the Notes are subject to adjustment by the Calculation Agent under certain circumstances, as described under "Reference Assets-Equity Securities-Share Adjustments Relating to Securities with an Equity Security as a Reference Asset" in the accompanying prospectus supplement.

PS-8

HYPOTHETICAL EXAMPLES OF AMOUNTS PAYABLE ON A SINGLE CONTINGENT COUPON PAYMENT DATE

The following examples demonstrate the circumstances under which you may receive a Contingent Coupon on a hypothetical Contingent Coupon Payment Date. The numbers appearing in these tables are purely hypothetical and are provided for illustrative purposes only. These examples do not take into account any tax consequences from investing in the Notes and make the following key assumptions:

* The hypothetical Initial Value of 100.00 and the hypothetical Coupon Barrier Value of 70.00 for each Reference Asset have been chosen for illustrative purposes only. The actual Initial Value and Coupon Barrier Value for each Reference Asset are as set forth on the cover of this pricing supplement.

Example 1: The Closing Value of each Reference Asset is greater than its Coupon Barrier Value on the relevant Observation Date.

Because the Closing Value of each Reference Asset is greater than its respective Coupon Barrier Value, you will receive a Contingent Coupon of $10.917 (1.0917% of the principal amount per Note) on the related Contingent Coupon Payment Date.

Example 2: The Closing Value of one Reference Asset is greater than its Coupon Barrier Value on the relevant Observation Date and the Closing Value of at least one Reference Asset is less than its Coupon Barrier Value on the relevant Observation Date.

Because the Closing Value of at least one Reference Asset is less than its Coupon Barrier Value, you will not receive a Contingent Coupon on the related Contingent Coupon Payment Date.

Example 3: The Closing Value of each Reference Asset is less than its Coupon Barrier Value on the relevant Observation Date.

Because the Closing Value of at least one Reference Asset is less than its Coupon Barrier Value, you will not receive a Contingent Coupon on the related Contingent Coupon Payment Date.

Examples 2 and 3 demonstrate that you may not receive a Contingent Coupon on a Contingent Coupon Payment Date. If the Closing Value of any Reference Asset is below its Coupon Barrier Value on each Observation Date, you will not receive any Contingent Coupons during the term of the Notes.

PS-9

HYPOTHETICAL EXAMPLES OF AMOUNTS PAYABLE AT MATURITY

The following table illustrates the hypothetical payment at maturity under various circumstances. The examples set forth below are purely hypothetical and are provided for illustrative purposes only. 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 assumptions:

* Thehypothetical Initial Value of 100.00, thehypothetical Coupon Barrier Value of 70.00 and thehypothetical Barrier Value of 50.00 for each Reference Asset have been chosen for illustrative purposes only. The actual Initial Value, Coupon Barrier Value and Barrier Value for each Reference Asset are as set forth on the cover of this pricing supplement.

** per $1,000 principal amount Note, excluding the final Contingent Coupon that may be payable on the Maturity Date.

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

Example 1: The Final Value of Reference Asset A is $135.00, the Final Value of Reference Asset B is $130.00, the Final Value of Reference Asset C is $140.00 and the Final Value of Reference Asset D is $145.00.

Because Reference Asset B has the lowest Reference Asset Return, Reference Asset B is the Least Performing Reference Asset. Because the Final Value of the Least Performing Reference Asset is greater than or equal to its Barrier Value, you will receive a payment at maturity of $1,000 per $1,000 principal amount Note that you hold (plus the Contingent Coupon that will otherwise be payable on the Maturity Date).

Example 2: The Final Value of Reference Asset A is $140.00, the Final Value of Reference Asset B is $90.00, the Final Value of Reference Asset C is $105.00 and the Final Value of Reference Asset D is $115.00.

Because Reference Asset B has the lowest Reference Asset Return, Reference Asset B is the Least Performing Reference Asset. Because the Final Value of the Least Performing Reference Asset is greater than or equal to its Barrier Value, you will receive a payment at maturity of $1,000 per $1,000 principal amount Note that you hold (plus the Contingent Coupon that will otherwise be payable on the Maturity Date).

PS-10

Example 3: The Final Value of Reference Asset A is $60.00, the Final Value of Reference Asset B is $120.00, the Final Value of Reference Asset C is $100.00 and the Final Value of Reference Asset D is $105.00.

Because Reference Asset A has the lowest Reference Asset Return, Reference Asset A is the Least Performing Reference Asset. Because the Final Value of the Least Performing Reference Asset is greater than or equal to its Barrier Value, you will receive a payment at maturity of $1,000 per $1,000 principal amount Note that you hold. Because, however, the Final Value of at least one Reference Asset is less than its Coupon Barrier Value, you will not receive a Contingent Coupon on the Maturity Date.

Example 4: The Final Value of Reference Asset A is $150.00, the Final Value of Reference Asset B is $40.00, the Final Value of Reference Asset C is $100.00 and the Final Value of Reference Asset D is $120.00.

Because Reference Asset B has the lowest Reference Asset Return, Reference Asset B is the Least Performing Reference Asset. Because the Final Value of the Least Performing Reference Asset is less than its Barrier Value, you will receive a payment at maturity of $400.00 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 × -60.00%] = $400.00

In addition, because the Final Value of at least one Reference Asset is less than its Coupon Barrier Value, you will not receive a Contingent Coupon on the Maturity Date.

Example 4 demonstrates that if the Notes are not redeemed prior to scheduled maturity, and if the Final Value of the Least Performing Reference Asset is less than its Barrier Value, your investment in the Notes will be fully exposed to the decline of the Least Performing Reference Asset from its Initial Value. You will not benefit in any way from the Reference Asset Return of any other Reference Asset being higher than the Reference Asset Return of the Least Performing Reference Asset.

If the Notes are not redeemed prior to scheduled maturity, youmay lose up to100.00% of the principal amount of your Notes. Any payment on the Notes, including the repayment of principal, is subject to the credit risk of Barclays Bank PLC.

PS-11

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, if any. 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.

Risks Relating to the Notes Generally

It is impossible to predict what the correlation among the Reference Assets will be over the term of the Notes. The Reference Assets represent different equity markets. These different equity markets may not perform similarly over the term of the Notes.

Although the correlation of the Reference Assets' performance may change over the term of the Notes, the Contingent Coupon rate is determined, in part, based on the correlation of the Reference Assets' performance calculated using our internal models at the time when the terms of the Notes are finalized. A higher Contingent Coupon is generally associated with lower correlation of the Reference Assets, which reflects a greater potential for missed Contingent Coupons and for a loss of principal at maturity.

PS-12

Accordingly, you should understand that a higher coupon payment amount reflects, among other things, an indication of a greater likelihood that you will (a) not receive coupon payments with respect to one or more Observation Dates and/or (b) incur a loss of principal at maturity than would have been the case had the amount of such coupon payments been lower. In addition, actual volatility over the term of the Notes may be significantly higher than the expected volatility at the time the terms of the Notes were determined. If actual volatility is higher than expected, you will face an even greater risk that you will not receive coupon payments and/or that you will lose some or all of your principal at maturity for the reasons described above.

The Redemption Price that you would receive on a Call Settlement Date, together with any coupon payments that you may have received prior to the Call Settlement Date, may be less than the aggregate amount of payments that you would have received had the Notes not been redeemed. There is no guarantee that you would be able to reinvest the proceeds from an investment in the Notes in a comparable investment with a similar level of risk in the event the Notes are redeemed prior to the Maturity Date. No additional payments will be due after the relevant Call Settlement Date. The fact that the Notes may be redeemed prior to maturity may also adversely impact your ability to sell your Notes and the price at which they may be sold.

It is more likely that we will redeem the Notes at our sole discretion prior to maturity to the extent that the expected interest payable on the Notes is greater than the interest that would be payable on other instruments issued by us of comparable maturity, terms and credit rating trading in the market. We are less likely to redeem the Notes prior to maturity when the expected interest payable on the Notes is less than the interest that would be payable on other comparable instruments issued by us, which includes when the value of any Reference Asset is less than its Coupon Barrier Value. Therefore, the Notes are more likely to remain outstanding when the expected interest payable on the Notes is less than what would be payable on other comparable instruments and when your risk of not receiving a Contingent Coupon is relatively higher.

Risks Relating to the Issuer

PS-13

Risks Relating to the Reference Assets

Risks Relating to Conflicts of Interest

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, if any. 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.

PS-14

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.

INFORMATION REGARDING THE REFERENCE ASSETS

We urge you to read the following section in the accompanying prospectus supplement: "Reference Assets-Equity Securities-Reference Asset Issuer and Reference Asset Information." Companies with securities registered under the Securities Exchange Act of 1934, as amended, which is commonly referred to as the "Exchange Act," and the Investment Company Act of 1940, as amended, which is commonly referred to as the "'40 Act," are required to periodically file certain financial and other information specified by the SEC. Information provided to or filed with the SEC electronically can be accessed through a website maintained by the SEC. The address of the SEC's website is http://www.sec.gov. Information provided to or filed with the SEC pursuant to the Exchange Act or the '40 Act by the company issuing each Reference Asset can be located by reference to the SEC file number specified below.

The summary information below regarding each Reference Asset comes from each company's respective SEC filings. You are urged to refer to the SEC filings made by the company and to other publicly available information (such as the company's annual report) to obtain an understanding of the company's business and financial prospects. The summary information contained below is not designed to be, and should not be interpreted as, an effort to present information regarding the financial prospects of any issuer or any trends, events or other factors that may have a positive or negative influence on those prospects or as an endorsement of any particular company. We have not undertaken any independent review or due diligence of the SEC filings of the issuer of any of the Reference Assets or of any other publicly available information regarding each such issuer.

Information from outside sources is not incorporated by reference in, and should not be considered part of, this pricing supplement or any accompanying prospectus or prospectus supplement. We have not undertaken any independent review or due diligence of the SEC filings of any Reference Asset or any other publicly available information regarding any of the Reference Assets.

TAX CONSIDERATIONS

You should review carefully the sections in the accompanying prospectus supplement entitled "Material U.S. Federal Income Tax Consequences-Tax Consequences to U.S. Holders-Notes Treated as Prepaid Forward or Derivative Contracts with Associated Contingent Coupons" and, if you are a non-U.S. holder, "-Tax Consequences to Non-U.S. Holders." The following discussion supersedes the discussion in the accompanying prospectus supplement to the extent it is inconsistent therewith.

In determining our reporting responsibilities, if any, we intend to treat (i) the Notes for U.S. federal income tax purposes as prepaid forward contracts with associated contingent coupons and (ii) any Contingent Coupon payments as ordinary income, as described in the section entitled "Material U.S. Federal Income Tax Consequences-Tax Consequences to U.S. Holders-Notes Treated as Prepaid Forward or Derivative Contracts with Associated Contingent Coupons" in the accompanying prospectus supplement. Our special tax counsel, Davis Polk & Wardwell LLP, has advised that it believes this treatment to be reasonable, but that there are other reasonable treatments that the Internal Revenue Service (the "IRS") or a court may adopt.

Sale, exchange or redemption of a Note. Assuming the treatment described above is respected, upon a sale or exchange of the Notes (including upon early redemption or redemption at maturity), you should recognize capital gain or loss equal to the difference between the amount realized on the sale or exchange and your tax basis in the Notes, which should equal the amount you paid to acquire the Notes (assuming Contingent Coupon payments are properly treated as ordinary income, consistent with the position referred to above). This gain or loss should be short-term capital gain or loss unless you hold the Notes for more than one year, in which case the gain or loss should be long-term capital gain or loss, whether or not you are an initial purchaser of the Notes at the issue price. The deductibility of capital losses is subject to limitations. If you sell your Notes between the time your right to a Contingent Coupon payment is fixed and the time it is paid, it is likely that you will be treated as receiving ordinary income equal to the Contingent Coupon payment. Although uncertain, it is possible that proceeds received from the sale or exchange of your Notes prior to an Observation Date but that can be attributed to an expected Contingent Coupon payment could be treated as ordinary income. You should consult your tax advisor regarding this issue.

As noted above, there are other reasonable treatments that the IRS or a court may adopt, in which case the timing and character of any income or loss on the Notes could be materially affected. In addition, in 2007 the U.S. Treasury Department and the IRS released a notice requesting comments on the U.S. federal income tax treatment of "prepaid forward contracts" and similar instruments. The notice focuses in particular on whether to require investors in these instruments to accrue income over the term of their investment. It also asks for comments on a number of related topics, including the character of income or loss with respect to these instruments and the relevance of factors such as the nature of the underlying property to which the instruments are linked. While the notice requests comments on appropriate transition rules and effective dates, any Treasury regulations or other guidance promulgated after consideration of these issues could materially affect the tax consequences of an investment in the Notes, possibly with retroactive effect. You should consult your tax advisor regarding the U.S. federal income tax consequences of an investment in the Notes, including possible alternative treatments and the issues presented by this notice.

Non-U.S. holders. Insofar as we have responsibility as a withholding agent, we do not currently intend to treat Contingent Coupon payments to non-U.S. holders (as defined in the accompanying prospectus supplement) as subject to U.S. withholding tax. 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, 2027 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.

PS-21

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.

We expect that delivery of the Notes will be made against payment for the Notes on the Issue Date, which is more than one business day following the Initial Valuation Date. Notwithstanding anything to the contrary in the accompanying prospectus supplement, under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes on any date prior to one business day before delivery will be required to specify alternative settlement arrangements to prevent a failed settlement and should consult their own advisor.

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 or application 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 July 12, 2024, filed as an exhibit to a report on Form 6-K by Barclays Bank PLC on July 12, 2024, and this opinion is subject to the same assumptions, qualifications and limitations as set forth in such opinion of Davis Polk & Wardwell London LLP.
