Pricing Agreement

May 8, 2024

Barclays Bank PLC

As representative of the several Underwriters

named in Schedule I (the “Representative”)

Ladies and Gentlemen:

Barclays PLC (the “Company”) proposes to issue £1,250,000,000 aggregate principal amount of 8.500% Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities (the “Designated Securities”). The Designated Securities are convertible in accordance with their terms for stock of Barclays PLC as described in the Preliminary Prospectus Supplement (as defined in Schedule II hereto). Each of the Underwriters hereby undertakes to purchase at the subscription price set forth in Schedule II hereto (the “Subscription Price”), the amount of Designated Securities set forth opposite the name of such Underwriter in Schedule I hereto, such payment to be made at the Time of Delivery set forth in Schedule II hereto. The obligations of the Underwriters hereunder are several but not joint.

Each of the provisions of the Underwriting Agreement—Standard Provisions, dated March 3, 2021 (the “Underwriting Agreement”), is incorporated herein by reference in its entirety, and shall be deemed to be a part of this Agreement to the same extent as if such provisions had been set forth in full herein, except as amended herein. For the purposes of this letter, a new Section 2(r) shall be included as follows: “The Company will promptly make a valid election in respect of the Designated Securities in accordance with the provisions of Section 475C of the Corporation Tax Act 2009 (“CTA 2009”). Following the making of a valid election pursuant to Section 475C of the CTA 2009, all payments of interest in respect of the Designated Securities will be deductible by the Company in computing its taxable profit for United Kingdom corporate income tax purposes and the Designated Securities will be “hybrid capital instruments” for United Kingdom tax purposes. The Designated Securities are not being issued in consequence of, or otherwise in connection with, any arrangements the main purpose, or one of the main purposes, of which is to secure a tax advantage;” and each of the representations and warranties set forth therein shall be deemed to have been made at and as of the date of this Agreement, except that each representation and warranty with respect to the Prospectus in Section 2 of the Underwriting Agreement shall be deemed to be a representation and warranty as of the date of the Prospectus and also a representation and warranty as of the date of this Agreement in relation to the Prospectus as amended or supplemented relating to the Designated Securities.

Each reference to the Representative herein and in the provisions of the Underwriting Agreement so incorporated by reference shall be deemed to refer to you. Unless otherwise defined herein, terms defined in the Underwriting Agreement are used herein as therein defined. The Representative designated to act on behalf of each of the Underwriters of the Designated Securities pursuant to Section 14 of the Underwriting Agreement and the address referred to in such Section 14 is set forth in Schedule II hereto.

Section 2(a) of the Underwriting Agreement is hereby amended to replace “File No. 333-253693” by “File No. 333-277578” in the first sentence thereof.

Notwithstanding Section 5 and any other provision to the contrary in the Underwriting Agreement, but without prejudice to Section 2(j) thereof, (i) the Designated Securities will be represented by one global certificate that will be deposited with a common depositary for Clearstream Banking, S.A. (“Clearstream”) and/or Euroclear S.A./N.V. (“Euroclear” and, together with Clearstream, the “Clearing Systems”), and registered in the name of such common depositary or its nominee and (ii) settlement of the Designated Securities will occur through the Clearing Systems for value. The Representative acknowledges

that the Designated Securities represented by the global certificate will initially be credited to an account with Euroclear or Clearstream, as the case may be (the “Commissionaire Account”) for the account of the Representative, the terms of which include a third-party beneficiary clause (‘stipulation pour autrui’) with the Company as the third-party beneficiary and provide that such Designated Securities are to be delivered to the Representative only against payment of the Subscription Price into the Commissionaire Account on a delivery against payment basis. The Representative acknowledges that (i) the Designated Securities represented by the global certificate shall be held to the order of the Company as set out above and (ii) the Subscription Price received in the Commissionaire Account will be held on behalf of the Company until such time as they are transferred to the Company’s order. The Representative undertakes that the Subscription Price will be transferred to the Company’s order promptly following receipt of such monies in the Commissionaire Account. The Company acknowledges and accepts the benefit of the third-party beneficiary clause (‘stipulation pour autrui’) pursuant to the Belgian or Luxembourg Civil Code, as applicable, in respect of the Commissionaire Account.

An amendment to the Registration Statement, or a supplement to the Prospectus, as the case may be, relating to the Designated Securities, in the form heretofore delivered to you, is now proposed to be filed with the Commission.

The Applicable Time for purposes of this Pricing Agreement is 4:45 p.m. London time on May 8, 2024. The “free writing prospectus” as defined in Rule 405 under the Securities Act for which each party hereto has received consent to use in accordance with Section 7 of the Underwriting Agreement is listed in Schedule III hereto and is attached as Exhibit A hereto.

Solely for the purposes of the requirements of 3.2.7R of the FCA Handbook Product Intervention and Product Governance Sourcebook (the “UK MiFIR Product Governance Rules”) regarding the mutual responsibilities of manufacturers under the UK MiFIR Product Governance Rules:

(a) each of the Underwriters designated a UK Manufacturer on Schedule II hereto (each a “UK Manufacturer”) acknowledges that it understands the responsibilities conferred upon it under the UK MiFIR Product Governance Rules relating to each of the product approval process, the target market and the proposed distribution channels as applying to the Designated Securities and the related information set out in the Registration Statement, the Prospectus, any Preliminary Prospectus, any Free Writing Prospectus or Issuer Free Writing Prospectus and any other announcements in connection with the Designated Securities; and

(b) each of the Company and each of the Underwriters that is not designated a UK Manufacturer note the application of the UK MiFIR Product Governance Rules and acknowledge the target market and distribution channels identified as applying to the Designated Securities by the UK Manufacturer and the related information set out in the Registration Statement, the Prospectus, any Preliminary Prospectus, any Free Writing Prospectus or Issuer Free Writing Prospectus and any other announcements in connection with the Designated Securities.

The execution of this Agreement on behalf of all parties hereto will constitute acceptance by each Underwriter of the ICMA Agreement Among Managers Version 1 (the “Agreement Among Managers”) subject to any amendment notified to such Underwriter in writing at any time prior to (i) its execution of this Agreement or (ii) the receipt by Barclays Bank PLC of the document appointing such Underwriter’s authorized signatory and its execution of this Agreement. References in the Agreement Among Managers to the “Lead Manager” and the “Settlement Lead Manager” shall be construed as references to Barclays Bank PLC. References in the Agreement Among Managers to “Commitments” shall mean the principal amounts or underwriting commitments in respect of the Designated Securities, set out opposite each Underwriter’s name in Schedule I hereto.

If the foregoing is in accordance with your understanding, please sign and return to us the counterpart hereof, and upon acceptance hereof by you and each of the other Underwriters, this letter and such acceptance hereof, including the provisions of the Underwriting Agreement incorporated herein by reference, shall constitute a binding agreement between each of the Underwriters on the one hand and the Company on the other.

No PRIIPs or U.K. PRIIPs key information document (KID) has been prepared as not available to retail in the EEA or in the U.K. No sales to retail clients (as defined in COBS 3.4) in the U.K.

It is expected that delivery of the Securities will be made for value on or about May 15, 2024, which will be the fifth (5th) business day in the United States following the date of pricing of the Securities. Under Rule 15c6-1 under the Securities Exchange Act of 1934, purchases or sales of Securities in the secondary market generally are required to settle within two (2) business days (T+2), unless the parties to any such transaction expressly agree otherwise.

Purchasers of the Securities who wish to trade the Securities prior to two business days before delivery should consult their own legal advisers.

Unless otherwise specified in the terms of the Contingent Capital Securities of a series in accordance with Section 3.01, if at any time a Taxing Jurisdiction requires the Company to deduct or withhold Taxes, the Company will pay the additional amounts of, or in respect of, any interest (but not principal or any premium) on such series of Contingent Capital Securities (“Additional Amounts”) that are necessary so that the net amounts in respect of interest paid to the Holders of such series of Contingent Capital Securities, after the deduction or withholding, shall equal the amounts in respect of interest which

4

would have been payable in respect of such series of Contingent Capital Securities had no such deduction or withholding been required. However, the Company will not pay Additional Amounts for Taxes:

(i) that are payable because the Holder or the Beneficial Owner of the Contingent Capital Securities is a domiciliary, national or resident of, or engages in business or maintains a permanent establishment or is physically present in, a Taxing Jurisdiction requiring that deduction or withholding, or otherwise has some connection with the Taxing Jurisdiction other than the holding or ownership of the relevant Contingent Capital Securities, or the collection of any payment of, or in respect of any interest on, any Contingent Capital Securities of the relevant series;

(ii) that are payable because (except in the case of a winding up of the Company in England) the relevant Contingent Capital Securities are presented for payment in the United Kingdom;

(iii) that are payable because the relevant Contingent Capital Securities are presented for payment more than thirty (30) days after the date payment became due or was provided for, whichever is later, except to the extent that the Holder of the relevant Contingent Capital Securities would have been entitled to the Additional Amounts on presenting the Contingent Capital Security for payment at the close of such thirty-day (30-day) period;

(iv) that are payable because the Holder or the Beneficial Owner of the relevant Contingent Capital Securities or the beneficial owner of any payment of (or in respect of) any interest on such Contingent Capital Securities failed to make any necessary claim or to comply with any certification, identification or other requirements concerning the nationality, residence, identity or connection with the Taxing Jurisdiction of such Holder, Beneficial Owner or beneficial owner, if such claim or compliance is required by statute, treaty, regulation or administrative practice of the Taxing Jurisdiction as a condition to relief or exemption from such Taxes; or

(v) if such Taxes would not have been so imposed, or would have been excluded pursuant to clauses (i) through (iv) above inclusive, if the beneficial owner of, or person ultimately entitled to obtain an interest in, such Contingent Capital Securities had been the Holder of such Contingent Capital Securities.

Whenever in this Contingent Capital Securities Indenture there is mentioned, in any context, the payment of any interest on, or in respect of, any Contingent Capital Security of any series, such mention shall be deemed to include mention of the payment of Additional Amounts provided for in this Section to the extent that, in context, Additional Amounts are, were or would be payable in respect thereof pursuant to the provisions of this Section and as if express mention of the payment of Additional Amounts (if applicable) were made in any provisions hereof where such express mention is not made. The limitations and restrictions on interest payments described under Sections 3.12 and 3.13 hereof shall apply to any Additional Amounts mutatis mutandis.”

5

(i) Sections 11.02, 11.03 and 11.04(a) of the Base Indenture are hereby amended by replacing the reference to “thirty (30)” appearing therein by “fifteen (15).”

(j) Section 11.08 of the Base Indenture is hereby amended and restated in its entirety as follows:

“Section 11.08 Limitations on Redemption. Notwithstanding any other provision in this Contingent Capital Securities Indenture and unless otherwise provided as contemplated by Section 3.01 with respect to any series of Contingent Capital Securities, the Company may redeem any series of Contingent Capital Securities (in the case of any series of Contingent Capital Securities with a Stated Maturity, before their Stated Maturity) (and give notice thereof to the Holders of the relevant Contingent Capital Securities) only if the Company has obtained the prior consent of the PRA and/or the Relevant U.K. Resolution Authority (in either case, if such consent is then required by the Capital Regulations) for the redemption of the Contingent Capital Securities. In addition, any such redemption of any series of Contingent Capital Securities shall be subject to the additional conditions set out in Section 11.13.”

(k) Section 11.10 of the Base Indenture is hereby amended and restated in its entirety as follows:

“Section 11.10 Condition to Repurchase. Unless otherwise provided as contemplated by Section 3.01 with respect to any series of Contingent Capital Securities, the Company or any member of the Group may purchase or otherwise acquire any Outstanding Contingent Capital Securities of any series at any price in the open market or otherwise in accordance with the Capital Regulations, and subject to the prior consent of the PRA and/or the Relevant U.K. Resolution Authority (in either case, if such consent is then required by the Capital Regulations) and to applicable law and regulations.

(l) A new Section 11.13 is hereby inserted into the Base Indenture as follows:

(ii) the Company has demonstrated to the satisfaction of the PRA that its “own funds” and “eligible liabilities” would, following such redemption or repurchase, exceed the relevant requirements for its own funds and eligible liabilities laid down in U.K. CRD and

6

in the U.K. legislation that implemented EU Directive 2014/59/EU, as amended from time to time, by a margin that the PRA considers necessary.

(b) in the case of any such redemption or repurchase of a particular series of Contingent Capital Securities before five years after the date of issuance of such Contingent Capital Securities, one of the following conditions in (i), (ii), (iii) or (iv) below being met, in each case, if and to the extent then required by the Capital Regulations:

(i) in the case of redemption due to the occurrence of a change in the regulatory classification of the relevant Contingent Capital Securities that does or would be likely to result in their exclusion from own funds or reclassification as own funds of lower quality (A) the PRA considers such change to be sufficiently certain and (B) the Company demonstrates to the satisfaction of the PRA that such regulatory reclassification was not reasonably foreseeable at the time of the issuance of the Contingent Capital Securities; or

(ii) in the case of redemption due to the occurrence of a Tax Event, the Company demonstrates to the satisfaction of the PRA that such Tax Event is material and was not reasonably foreseeable at the time of issuance of the relevant Contingent Capital Securities; or

(iii) before or at the same time as such redemption or repurchase of the relevant Contingent Capital Securities, the Company replaces such Contingent Capital Securities with own funds instruments of equal or higher quality at terms that are sustainable for the Company’s income capacity and the PRA has permitted that action on the basis of the determination that it would be beneficial from a prudential point of view and justified by exceptional circumstances; or

(iv) the relevant Contingent Capital Securities are repurchased for market making purposes.

Notwithstanding the conditions set out above, if, at the time of any such redemption or repurchase, the Capital Regulations permit the redemption or repurchase of a particular series of Contingent Capital Securities only after compliance with one or more alternative or additional pre-conditions to those set out above, the Company will comply with such other and/or, as appropriate, additional pre-condition(s).”

(m) Section 13.01(a) of the Base Indenture is hereby amended by adding “or the Trustee on behalf of the Holders of the Contingent Capital Securities,” after “Notwithstanding and to the exclusion of any other term of the Contingent Capital Securities or any other agreements, arrangements, or understandings between the Company and any Holder or Beneficial Owner of the Contingent Capital Securities” and before “by acquiring any Contingent Capital Securities, each Holder and Beneficial Owner of the Contingent Capital Securities 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”.

ARTICLE I

DEFINITIONS AND OTHER PROVISIONS OF GENERAL APPLICATION

SECTION 1.01. Definitions.

Except as otherwise expressly provided or unless the context otherwise requires, all terms used in this Eleventh Supplemental Indenture that are defined in the Base Indenture shall have the meanings ascribed to them in the Base Indenture. The following terms used in this Eleventh Supplemental Indenture have the following respective meanings with respect to the Securities only:

“Acquirer” means the Takeover Person that controls the Company following a Takeover Event. For the purposes of this definition, “control” means the acquisition or holding of legal or beneficial ownership of more than 50% of the votes which may ordinarily be cast on a poll at a general meeting of the Company or the right to appoint or remove a majority of the board of directors of the Company.

“Adjustment Spread” means a spread (which may be positive or negative) or formula or methodology for calculating a spread, which the Independent Benchmark Adviser (in consultation with the Company) or the Company (as applicable), determines is required to be applied to the Successor Rate or the Alternative Reference Rate (as applicable) in order to reduce or eliminate, to the extent reasonably practicable in the circumstances, any economic prejudice or benefit (as applicable) to the Holders of Securities as a result of the replacement of the Reference Rate with the Successor Rate or the Alternative Reference Rate (as applicable) and is the spread, formula or methodology which:

(i) in the case of a Successor Rate, is recommended in relation to the replacement of the Reference Rate with the Successor Rate by any Relevant Nominating Body;

(ii) in the case of a Successor Rate for which no such recommendation has been made or in the case of an Alternative Reference Rate, the Independent Benchmark Adviser (in consultation with the Company) or the Company (as applicable) determines is recognized or acknowledged as being in customary market usage in international debt capital markets transactions which reference the Reference Rate, where such rate has been replaced by the Successor Rate or the Alternative Reference Rate (as applicable); or

(iii) if no such customary market usage is recognized or acknowledged, the Independent Benchmark Adviser (in consultation with the Company) or the Company in its discretion (as applicable), determines (acting in good faith and in a commercially reasonable manner) to be appropriate.

“Alternative Reference Rate” means the rate that the Independent Benchmark Adviser or the Company (as applicable) determines has replaced the Reference Rate in

Such shares shall cease to be “Approved Entity Shares” if they do not satisfy the definition above on the Conversion Date. In relation to an Automatic Conversion in respect of which the Conversion Date falls on or after the QTE Effective Date, references herein to “Conversion Shares” shall be deemed to be references to “Approved Entity Shares”.

“Automatic Conversion” means the irrevocable and automatic release of all of the Company’s obligations under the Securities (other than the CSO Obligations, if any) in consideration of the Company’s issuance of the Conversion Shares at the Conversion Price to the Conversion Shares Depository (on behalf of the Holders and Beneficial Owners of the Securities) or to the relevant recipient of such Conversion Shares, all in accordance with the terms of the Securities.

(a) There is hereby established a new series of Contingent Capital Securities under the Base Indenture entitled the “£1,250,000,000 8.500% Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities.”

(b) The Securities shall be issued initially in the form of one registered Global Security that shall be deposited with the Common Depositary on the Issue Date.

(c) The Company shall issue the Securities in an aggregate principal amount of £1,250,000,000. The Company may from time to time, without the consent of the Holders of the Securities, issue additional securities having the same ranking and same interest rate, interest cancellation terms, redemption terms, Conversion Price and other terms as the Securities described in this Eleventh Supplemental Indenture, except for the price to public and date of issue. Any such additional securities subsequently issued shall rank equally and ratably with the Securities in all respects, so that such further securities shall be consolidated and form a single series with the Securities.

(d) Any proposed transfer of an interest in Securities held in the form of a Global Security deposited with the Common Depositary shall be effected in the ordinary way following the applicable rules and operating procedures of the Clearing Systems.

(e) The Securities shall not have a sinking fund.

(f) The Securities shall be issued on May 15, 2024 (the “Issue Date”).

(j) The denomination of each interest in the Global Security shall be the “Tradable Amount” of such book-entry interest. Prior to an Automatic Conversion, the aggregate Tradable Amount of the interests in each Global Security shall be equal to such Global Security’s outstanding principal amount. Following an Automatic Conversion, the principal amount of each Security shall be zero, but the Tradable Amount of the book-entry interests in each Security shall remain unchanged.

SECTION 2.02. Interest.

(a) From (and including) the Issue Date to (but excluding) December 15, 2030, the interest rate on the Securities shall be 8.500% per annum (the “Initial Interest Rate”). From and including each Reset Date to (but excluding) the next following Reset Date (each such period, a “Reset Period”), the applicable per annum interest rate (the “Subsequent Interest Rate”) will, subject to Section 2.02(b) and Section 2.02(d) herein, be equal to the sum, as determined by the Calculation Agent, of the applicable Mid-Market Swap Rate on the relevant Reset Determination Date and 4.881% (the “Margin”), converted to a quarterly rate in accordance with market convention as instructed by the Company (rounded to three decimal places, with 0.0005 rounded down). Each Subsequent Interest Rate shall be determined in compliance with the relevant Capital Regulations. Subject to Sections 3.12 and 3.13 of the Base Indenture and the penultimate sentence of this paragraph, interest, if any, shall be payable quarterly in arrear on March 15, June 15, September 15 and December 15 of each year (each, an “Interest Payment Date”), commencing on September 15, 2024; provided that if such Interest Payment Date is not a Business Day, the Interest Payment Date shall be postponed to the next Business Day, but interest on that payment will not accrue during the period from and after the Interest Payment Date. Subject to Sections 3.12 and 3.13 of the Base Indenture, interest on the Securities, if any, will be computed and payable as follows:

(i) if the Calculation Period is equal to or shorter than the Regular Period during which it falls, interest on the Securities, if any, will be computed and payable on the basis of the number of days in the Calculation Period, divided by the product of (1) the number of days in the Regular Period in which the Calculation Period falls and (2) four; or

(ii) if the Calculation Period is longer than one Regular Period, interest on the Securities, if any, will be computed and payable on the basis of the sum of: (A) the number of days in such Calculation Period falling in the Regular Period in which it begins divided by the product of (1) the number of days in such Regular Period and (2) four; and (B) the number of days in such Calculation Period falling in the next Regular Period divided by the product of (1) the number of days in such Regular Period and (2) four.

The first date on which interest may be paid will be September 15, 2024 for the period commencing on (and including) May 15, 2024 and ending on (but excluding) September 15, 2024 (and thus a long first interest period). If a date of redemption is not a Business Day, the

- 20 -

Company may pay interest (if any) and principal on the next Business Day, but interest on that payment will not accrue during the period from and after the date of redemption.

(b) In addition to and notwithstanding the provisions in Section 2.02(a) above, if the Company determines that a Benchmark Event has occurred or that there is a Successor Rate, in either case when any Subsequent Interest Rate (or the relevant component part thereof) remains to be determined by reference to the Reference Rate, then the Company may elect (acting in good faith and in a commercially reasonable manner) to apply the following provisions:

(i) the Company shall use reasonable endeavors to appoint, as soon as reasonably practicable, an Independent Benchmark Adviser to determine (acting in good faith and in a commercially reasonable manner), no later than five (5) Business Days prior to the relevant Reset Determination Date relating to the next succeeding Reset Period (the “IA Determination Cut-off Date”), a Successor Rate or, alternatively, if the Independent Benchmark Adviser determines that there is no Successor Rate, an Alternative Reference Rate for purposes of determining the Subsequent Interest Rate (or the relevant component part thereof) applicable to the Securities;

(ii) if the Company is unable to appoint an Independent Benchmark Adviser, or the Independent Benchmark Adviser appointed by it fails to determine a Successor Rate or an Alternative Reference Rate prior to the IA Determination Cut-off Date, the Company (acting in good faith and in a commercially reasonable manner) may determine a Successor Rate or, if the Company determines that there is no Successor Rate, an Alternative Reference Rate;

(iii) if a Successor Rate or, failing which, an Alternative Reference Rate (as applicable) is determined in accordance with the preceding provisions, such Successor Rate or, failing which, an Alternative Reference Rate (as applicable) shall be used in place of the Reference Rate as a component part for determining the relevant Mid-Market Swap Rate in respect of each of the future Reset Periods (subject to the subsequent operation of, and to adjustment as provided in, this Section 2.02(b)); provided, however, that if sub-paragraph (ii) applies and the Company is unable to or does not determine a Successor Rate or an Alternative Reference Rate prior to the relevant Reset Determination Date, the Subsequent Interest Rate applicable to the next succeeding Reset Period shall be equal to the Subsequent Interest Rate last determined in relation to the Securities in respect of the preceding Reset Period (or alternatively, in the case of the first Reset Period, the rate of interest shall be the Initial Interest Rate); for the avoidance of doubt, the proviso in this sub-paragraph (iii) shall apply to the relevant Reset Period only and any subsequent Reset Periods are subject to the subsequent operation of, and to adjustment as provided in this Section 2.02(b);

(iv) if the Independent Benchmark Adviser (in consultation with the Company) or (if the Company is unable to appoint an Independent Benchmark Adviser, or the Independent Benchmark Adviser appointed by it fails to determine whether an Adjustment Spread should be applied) the Company (acting in good faith and in a commercially reasonable manner) determines that an Adjustment Spread should be

- 21 -

applied to the relevant Successor Rate or the relevant Alternative Reference Rate (as applicable) and determines the quantum of, or a formula or methodology for determining, such Adjustment Spread, then such Adjustment Spread shall be applied to such Successor Rate or Alternative Reference Rate (as applicable). If the Independent Benchmark Adviser or the Company (as applicable) is unable to determine, prior to the Reset Determination Date relating to the next succeeding Reset Period, the quantum of, or a formula or methodology for determining, such Adjustment Spread, then such Successor Rate or Alternative Reference Rate (as applicable) will apply without an Adjustment Spread;

(v) if the Independent Benchmark Adviser or the Company determines a Successor Rate or, failing which, an Alternative Reference Rate (as applicable) and, in each case, any Adjustment Spread in accordance with the above provisions, the Independent Benchmark Adviser or the Company (as applicable), may also specify changes to the terms of the Securities, including but not limited to the Day Count Fraction, business day convention, Relevant Screen Page, Reset Determination Date and/or the definitions of the relevant Reference Rate, Mid-Market Swap Rate and/or business day applicable to the Securities, and the method for determining the fallback rate in relation to the Securities, in order to follow market practice in relation to the Successor Rate, the Alternative Reference Rate (as applicable) and/or the Adjustment Spread. For the avoidance of doubt, the Trustee, the Paying Agent and the Calculation Agent shall, at the direction and expense of the Company, effect such consequential amendments to the Indenture and other agreements or documents as may be required in order to give effect to this Section 2.02(b); provided, however, that none of the Trustee, the Paying Agent or the Calculation Agent shall be obligated to effect any such amendment which affects its own rights, duties or immunities under the Indenture, any paying agency agreement, any calculation agency agreement or otherwise. The consent of the Holders of the Securities shall not be required in connection with implementing the Successor Rate, Alternative Reference Rate (as applicable) and/or any Adjustment Spread or such other changes, including for the execution of any documents, amendments or other steps by the Trustee, the Paying Agent or the Calculation Agent (if required); and

(vi) the Company shall promptly, following the determination of any Successor Rate, Alternative Reference Rate (as applicable) and/or any Adjustment Spread, give notice thereof to the Trustee, the Paying Agent, the Calculation Agent and the Holders of the Securities, which shall specify the effective date(s) for such Successor Rate, Alternative Reference Rate (as applicable) and/or any Adjustment Spread and any consequential changes made to the terms of the Securities and the Indenture,

provided that the determination of any Successor Rate or Alternative Reference Rate or Adjustment Spread, and any other related changes to the Securities, shall be made in accordance with the relevant Capital Regulations (if applicable) and shall not prejudice the then current capital or eligible liabilities qualification of the Securities, as applicable, in each case for the purposes of and in accordance with the Capital Regulations. None of the Trustee, the Paying Agent, any other paying agent or the Calculation Agent shall have any duty to determine whether a Benchmark Event has occurred or that there is a Successor Rate.

- 22 -

(c) Notwithstanding and to the exclusion of any other term of the Securities or any other agreements, arrangements, or understandings between the Company and any Holder or Beneficial Owner of the Securities, or the Trustee on behalf of the Holders of the Securities, by acquiring the Securities, each Holder and Beneficial Owner of the Securities acknowledges, accepts, agrees to be bound by and consents to the determinations made by the Company, the Independent Benchmark Adviser, the Trustee, the Paying Agent, the Calculation Agent or other relevant entities, as applicable, to determine the Subsequent Interest Rate in the event the Company determines that a Benchmark Event has occurred or that there is a Successor Rate, including as may occur without any prior notice from the Company and without the need for the Company to obtain any further consent from Holders and Beneficial Owners of the Securities to implement consequential amendments to the Indenture and other agreements or documents relating to the Securities.

(d) In addition to any other restrictions on payments of principal and interest contained in the Indenture, no repayment of the principal amount of the Securities or payment of interest on the Securities shall become due and payable after the exercise of any U.K. Bail-in Power by the Relevant U.K. Resolution Authority unless such repayment or payment would be permitted to be made by the Company under the laws and regulations of the United Kingdom and the European Union applicable to the Company.

SECTION 2.03. Payment of Principal, Interest and Other Amounts.

(a) Payments of principal of and interest, if any, on the Securities shall be made in such coin or currency of the United Kingdom as at the time of payment is legal tender for payment of public and private debts and such payments on Securities represented by the Global Security shall be made through one or more Paying Agents appointed under the Base Indenture to the Clearing Systems, or the Common Depositary or its nominee, as the Holder or Holders of the Global Security. Initially, the Paying Agent for the Securities shall be The Bank of New York Mellon, London Branch, 160 Queen Victoria Street, London EC4V 4LA, United Kingdom and the Contingent Capital Security Registrar shall be The Bank of New York Mellon SA/NV, Luxembourg Branch, 2-4 Rue Eugene Ruppert, Vertigo Building – Polaris, Luxembourg, L-2453, Luxembourg. The Company may change the Paying Agent without prior notice to the Holders of the Securities, and in such an event the Company may act as Paying Agent or Contingent Capital Security Registrar. Payments of principal of and interest on the Securities represented by the Global Security shall be made by wire transfer of immediately available funds; provided, however, that in the case of payments of principal, such Global Security is first surrendered to the Paying Agent.

(b) If, on any date on which a payment in respect of the Securities is contemplated, sterling is unavailable to the Company due to the imposition of exchange controls or other circumstances beyond the Company’s control or is no longer used for the settlement of transactions by public institutions within the international banking community, then all payments in respect of the Securities will be made in U.S. dollars until sterling is again available to the Company or so used. The amount payable on any date in sterling will be converted into U.S. dollars at the Prevailing Rate as of the close of business on the second Payment Business Day prior to the relevant payment date. Any payment in respect of the Securities so made in U.S. dollars will not constitute a Winding-up Event, a Non-Payment Event, a Default or otherwise

- 23 -

under the Indenture or the Securities. Neither the Trustee, the Paying Agent or any other agent will be responsible for obtaining exchange rates, effecting currency conversions or otherwise handling re-denominations.

SECTION 2.04. Optional Redemption. Subject to the limitations specified in Section 2.07 of this Eleventh Supplemental Indenture and Section 11.08 and Section 11.13 of the Base Indenture, the Company may, at the Company’s option, redeem the Securities, in whole but not in part, on any day falling in the period commencing on (and including) June 15, 2030, and ending on (and including) the first Reset Date or on any day falling in the period commencing on (and including) the date that is six months before any subsequent Reset Date and ending on (and including) such Reset Date at a redemption price equal to 100% of the principal amount of the Securities then Outstanding, together with any accrued but unpaid interest (which excludes any interest cancelled or deemed cancelled as described in Sections 3.12 and 3.13 of the Base Indenture) to (but excluding) the date fixed for redemption.

SECTION 2.05. Regulatory Event Redemption. Subject to Section 2.07 of this Eleventh Supplemental Indenture and Section 11.08 and Section 11.13 of the Base Indenture, the Company may, at the Company’s option, at any time, redeem the Securities, in whole but not in part, at a redemption price equal to 100% of the principal amount of the Securities then Outstanding, together with any accrued but unpaid interest (which excludes any interest cancelled or deemed cancelled as described in Sections 3.12 and 3.13 of the Base Indenture) to (but excluding) the date fixed for redemption, if, on or after the Issue Date, there is a change in the regulatory classification of the Securities that does, or would be likely to, result in the whole or any part of the outstanding aggregate principal amount of the Securities at any time being excluded from, or ceasing to count towards, the Group’s Tier 1 Capital (a “Regulatory Event”).

SECTION 2.06. Clean-Up Call. Subject to Section 2.07 of this Eleventh Supplemental Indenture and Section 11.08 and Section 11.13 of the Base Indenture, if, at any time from the fifth anniversary of the Issue Date (unless otherwise permitted by the PRA), the outstanding aggregate principal amount of the Securities is 25% or less of the aggregate principal amount of the Securities originally issued (and, for these purposes, any additional securities issued as set out under Section 2.01(c) of this Eleventh Supplemental Indenture shall be deemed to have been originally issued), the Company may redeem all (but not some only) of the Outstanding Securities at a redemption price equal to 100% of their principal amount, together with any accrued but unpaid interest (which excludes any interest cancelled or deemed cancelled as described in Sections 3.12 and 3.13 of the Base Indenture) to (but excluding) the date fixed for redemption.

SECTION 2.07. Notice of Redemption. Before the Company may redeem the Securities pursuant to Section 2.04, Section 2.05 or Section 2.06 of this Eleventh Supplemental Indenture or Section 11.12 of the Base Indenture, the Company shall deliver via the Clearing Systems (or, if the Securities are definitive Securities, to the Holders at their addresses shown on the Contingent Capital Security Register) prior notice of not less than fifteen (15) days, nor more than sixty (60) days to the Holders of the Securities. The Company shall deliver written notice of such redemption of the Securities to the Trustee at least five (5) Business Days prior to the date on which the relevant notice of redemption is sent to Holders (unless a shorter notice period shall be satisfactory to the Trustee). Such notice shall specify the

- 24 -

Company’s election to redeem the Securities and the date fixed for such redemption and shall be irrevocable except in the limited circumstances described in Sections 11.04(d), (e) and (f) of the Base Indenture. The Company shall not be entitled to deliver a notice of redemption after an Automatic Conversion Notice has been delivered.

SECTION 2.08. Automatic Conversion upon Capital Adequacy Trigger Event.

(a) If a Capital Adequacy Trigger Event has occurred, then the Automatic Conversion shall occur on the Conversion Date, at which point all of the Company’s obligations under the Securities (other than the CSO Obligations, if any) shall be irrevocably and automatically released in consideration of the Company’s issuance of the Conversion Shares to the Conversion Shares Depository (or to the relevant recipient in accordance with the terms of the Securities) on the Conversion Date at the Conversion Price. Under no circumstances shall such released obligations be reinstated. If the Company has been unable to appoint a Conversion Shares Depository, it shall make such other arrangements for the issuance and/or delivery of the Conversion Shares or Conversion Shares Offer Consideration, as applicable, to the Holders of the Securities as it shall consider reasonable in the circumstances (including, without limitation, issuance of the Conversion Shares to another nominee or to the Holders of the Securities directly), and such issuance shall irrevocably and automatically release all of the Company’s obligations under the Securities (other than the CSO Obligations, if any) as if the Conversion Shares had been issued to the Conversion Shares Depository.

(b) The Automatic Conversion shall occur without delay upon the occurrence of a Capital Adequacy Trigger Event.

(c) The Company shall (a) immediately inform the PRA of the occurrence of a Capital Adequacy Trigger Event and (b) deliver an Automatic Conversion Notice to the Trustee directly and to the Holders through the Clearing Systems as soon as practicable after such time.

(d) The date on which the Automatic Conversion Notice shall be deemed to have been given shall be the date on which it is dispatched by the Company to each of the Clearing Systems (or, if the Securities are definitive Securities, to the Trustee).

(e) The Company shall request that each of the Clearing Systems, pursuant to the applicable rules and operating procedures of such Clearing System then in effect, transmit the Automatic Conversion Notice to the direct participants of such Clearing System holding the Securities at such time.

(f) The Automatic Conversion shall occur on the Conversion Date and all of the Company’s obligations under the Securities (other than the CSO Obligations, if any) shall be irrevocably and automatically released in consideration of the Company’s issuance of the Conversion Shares to the Conversion Shares Depository (or to the relevant recipient in accordance with the terms of the Securities), and the principal amount of the Securities shall equal zero at all times thereafter (for the avoidance of doubt, the Tradable Amount shall remain unchanged) as a result of the Automatic Conversion.

- 25 -

(g) Within ten (10) Business Days following the Conversion Date, the Company shall deliver a Conversion Shares Offer Notice to the Trustee directly and to the Holders of the Securities through the Clearing Systems (or, if the Securities are definitive Securities, by the Company to the Trustee directly and to the Holders at their addresses shown on the Contingent Capital Security Register).

(h) The Conversion Shares shall initially be registered in the name of the Conversion Shares Depository (or the relevant recipient in accordance with the terms of the Securities, as applicable) and each Holder and Beneficial Owner of the Securities shall be deemed to have irrevocably directed the Company to issue the Conversion Shares corresponding to the conversion of its holding of Securities to the Conversion Shares Depository (or to such other relevant recipient).

(i) The Conversion Shares Depository (or the relevant recipient in accordance with the terms of the Securities, as applicable) shall hold the Conversion Shares on behalf of the Holders and Beneficial Owners of the Securities, who shall be entitled to direct (each in respect of their pro rata share of the Conversion Shares) the Conversion Shares Depository or such other relevant recipient, as applicable, to exercise on their behalf all rights of an ordinary shareholder (including voting rights and rights to receive dividends); provided, however, that Holders and Beneficial Owners shall not be able to sell or otherwise transfer the Conversion Shares until such time as the Conversion Shares have been delivered to the Holders or Beneficial Owners in accordance with the procedures set forth under Section 2.11 hereof. A Holder or Beneficial Owner’s pro rata share of the Conversion Shares at any particular time shall be determined based on the aggregate amount of the Tradable Amount of the Securities held by such Holder or Beneficial Owner as a proportion of the aggregate amount of the Tradable Amount of all Securities outstanding at the relevant time rounded down, if necessary, to the nearest whole number of Conversion Shares.

(j) Provided that the Company issues the Conversion Shares to the Conversion Shares Depository (or the relevant recipient in accordance with the terms of the Securities) in accordance with the terms of the Securities, with effect from the Conversion Date, Holders and Beneficial Owners of the Securities shall have recourse only to the Conversion Shares Depository (or to such other relevant recipient, as applicable) for the delivery to them of Conversion Shares or, if the Company elects that a Conversion Shares Offer be made, of any Conversion Shares Offer Consideration to which such Holders and Beneficial Owners are entitled.

(k) Effective upon, and following, the occurrence of the Automatic Conversion, Holders and Beneficial Owners shall not have any rights against the Company with respect to repayment of the principal amount of the Securities or payment of interest or any other amounts in respect of or arising under such Securities, which liabilities of the Company shall be irrevocably and automatically released, and accordingly the principal amount of the Securities shall equal zero at all times thereafter. Any interest in respect of an interest period ending on any Interest Payment Date falling between the date of a Capital Adequacy Trigger Event and the Conversion Date shall be deemed to have been cancelled pursuant to Section 3.12 of the Base Indenture upon the occurrence of such Capital Adequacy Trigger Event and shall not be due and payable.

- 26 -

(l) By subscribing for, purchasing or otherwise acquiring the Securities, each Holder and each Beneficial Owner shall be deemed to have (i) acknowledged and agreed that an interest payment shall not be due and payable on the relevant Interest Payment Date if it has been cancelled or deemed cancelled (in each case, in whole or in part) for any reason in accordance with the terms of the Securities, (ii) consented to (x) the Automatic Conversion, including the appointment of a Conversion Shares Depository and the issuance of the Conversion Shares thereto (or any related Conversion Shares Offer Consideration, including the appointment of any Conversion Shares Offer Agent and the sale of the Conversion Shares by the Conversion Shares Depository), and acknowledged that such Automatic Conversion of its Securities (and any related Conversion Shares Offer) may occur without any further action on the part of such Holder or Beneficial Owner or the Trustee and (y) the exercise of any U.K. Bail-in Power as it may be imposed without any prior notice by the Relevant U.K. Resolution Authority of its decision to exercise such power with respect to the Securities and (iii) authorized, directed and requested the Clearing Systems, their respective direct or indirect participants or any other intermediary through which they hold such Securities to take any and all necessary action, if required, to implement (x) the Automatic Conversion (including any related Conversion Shares Offer) and (y) the exercise of any U.K. Bail-in Power with respect to the Securities as it may be imposed, without any further action or direction on the part of such Holder or Beneficial Owner or the Trustee.

(m) The procedures set forth in this Section 2.08 are subject to change to reflect changes in the Clearing Systems’ practices, and the Company may make changes to the procedures set forth in this Section 2.08 to the extent reasonably necessary, in the opinion of the Company, to reflect such changes in the Clearing Systems’ practices.

(n) Notwithstanding anything to the contrary contained in the Indenture or the Securities, once the Company has delivered an Automatic Conversion Notice to each of the Clearing Systems following the occurrence of a Capital Adequacy Trigger Event (or following an Automatic Conversion (if sooner)), (i) the Holders and Beneficial Owners shall have no rights whatsoever under the Indenture or the Securities to instruct the Trustee to take any action whatsoever and (ii) as of the date of the Automatic Conversion Notice, except for any indemnity and/or security provided by any Holder or by any Beneficial Owner in such direction or related to such direction, any direction previously given to the Trustee by any Holders or by any Beneficial Owners shall cease automatically and shall be null and void and of no further effect; except in each case of (i) and (ii) of this Section 2.08(n), with respect to any rights of Holders or Beneficial Owners with respect to any payments under the Securities that were unconditionally due and payable prior to the date of the Automatic Conversion Notice (if any) or unless the Trustee is instructed in writing by the Company to act otherwise.

(o) On or (if reasonably practicable) prior to delivering the Automatic Conversion Notice, the Company shall deliver to the Trustee a certificate signed by two Authorized Officers, in the form attached hereto as Exhibit C, specifying that a Capital Adequacy Trigger Event has occurred (the “Capital Adequacy Trigger Event Officers’ Certificate”). The Trustee is entitled to conclusively rely on and accept such Capital Adequacy Trigger Event Officers’ Certificate without any duty whatsoever of further inquiry as sufficient and conclusive evidence of the occurrence of a Capital Adequacy Trigger Event, and such

- 27 -

Capital Adequacy Trigger Event Officers’ Certificate shall be conclusive and binding on the Trustee, the Holders and the Beneficial Owners.

(p) All authority conferred or agreed to be conferred by each Holder and Beneficial Owner pursuant to this Section 2.08, including the consents given by such Holder and Beneficial Owner, shall be binding upon the successors, assigns, heirs, executors, administrators, trustees in bankruptcy and legal representatives of such Holder and Beneficial Owner.

(q) The Trustee shall not be liable with respect to (i) the calculation or accuracy of the Fully Loaded CET1 Ratio in connection with the occurrence of a Capital Adequacy Trigger Event and the timing of such Capital Adequacy Trigger Event, (ii) the failure of the Company to post or deliver the underlying Fully Loaded CET1 Ratio calculations of a Capital Adequacy Trigger Event to the Clearing Systems, the Holders or the Beneficial Owners, (iii) any aspect of the Company’s decision to deliver an Automatic Conversion Notice or the related Automatic Conversion or (iv) the adequacy of the disclosure of these provisions in the Prospectus Supplement or for the direct or indirect consequences thereof.

(r) Following the issuance of the Conversion Shares to the Conversion Shares Depository (or to the relevant recipient in accordance with the terms of the Securities) on the Conversion Date, the Securities shall remain in existence until the applicable Cancellation Date for the sole purpose of evidencing (a) the Holders’ and Beneficial Owners’ right to receive Conversion Shares or Conversion Shares Offer Consideration, as applicable, from the Conversion Shares Depository (or such other relevant recipient, as applicable) and (b) the Company’s CSO Obligations, if any.

(s) The Holders and Beneficial Owners shall not at any time have the option to convert to the Securities into Conversion Shares.

(t) The occurrence of an Automatic Conversion shall not constitute a Default.

(u) Notwithstanding any other provision herein, by subscribing for, purchasing or otherwise acquiring the Securities, each Holder and each Beneficial Owner (i) agrees to all of the terms of the Securities, including, without limitation, those related to (x) the occurrence of a Capital Adequacy Trigger Event and any related Automatic Conversion and (y) the appointment of the Conversion Shares Depository, the issuance of the Conversion Shares to the Conversion Shares Depository (or to the relevant recipient in accordance with the terms of the Securities) and the potential sale of the Conversion Shares pursuant to a Conversion Shares Offer, (ii) agrees that effective upon, and following, the occurrence of the Automatic Conversion, no amount shall be due and payable to the Holders or the Beneficial Owners under the Securities and the liability of the Company to pay any such amounts (including the principal amount of, or any interest in respect of, the Securities) shall be automatically released, and the Holders and the Beneficial Owners shall not have the right to give any direction to the Trustee with respect to the Capital Adequacy Trigger Event and any related Automatic Conversion and (iii) waives, to the extent permitted by the Trust Indenture Act, any claim against the Trustee arising out of its acceptance of its trusteeship for the Securities, including, without limitation, claims related to or arising out of or in connection with a Capital Adequacy Trigger Event and/or any Automatic Conversion.

- 28 -

SECTION 2.09. Conversion Shares.

(a) The number of Conversion Shares to be issued to the Conversion Shares Depository on the Conversion Date shall be determined by the Company by dividing the (i) aggregate principal amount of the Outstanding Securities immediately prior to the Automatic Conversion on the Conversion Date by (ii) the Conversion Price rounded down, if necessary, to the nearest whole number of Conversion Shares. Fractions of Conversion Shares shall not be issued following an Automatic Conversion and no cash payment shall be made in lieu thereof. Upon Automatic Conversion on the Conversion Date, the number of Conversion Shares to be held by the Conversion Shares Depository for the benefit of each Holder shall be the number of Conversion Shares thus calculated multiplied by a fraction equal to the aggregate amount of the Tradable Amount of the book-entry interests in the Securities held by such Holder on the Conversion Date divided by the aggregate amount of the Tradable Amount of the book-entry interests of all the Outstanding Securities immediately prior to the Automatic Conversion on the Conversion Date rounded down, if necessary, to the nearest whole number of Conversion Shares.

(b) The Conversion Shares issued following an Automatic Conversion shall be fully paid and non-assessable and shall in all respects rank pari passu with the fully paid Ordinary Shares of the Company in issue on the Conversion Date, except in any such case for any right excluded by mandatory provisions of applicable law, and except that the Conversion Shares so issued shall not rank for (or, as the case may be, the relevant Holder or Beneficial Owner shall not be entitled to receive) any rights, the entitlement to which falls prior to the Conversion Date.

(c) Subject to Section 3.05 hereof, if a Qualifying Takeover Event occurs, and the Conversion Date falls on or after the QTE Effective Date, then in such case Approved Entity Shares of the Approved Entity shall be issued to the Conversion Shares Depository on the Conversion Date instead of Conversion Shares with the same effect as if Conversion Shares had been issued pursuant to Section 2.09(a) above.

(d) The Conversion Shares or the Conversion Shares Offer Consideration, as the case may be, will be delivered to Holders pursuant to the procedures set forth in Section 2.11 below.

SECTION 2.10. Conversion Shares Offer.

(a) No later than 10 (ten) Business Days following the Conversion Date, the Company may, in its sole and absolute discretion, elect that the Conversion Shares Depository make an offer of all or some of the Conversion Shares to all or some of the Company’s ordinary shareholders at a cash price per Conversion Share equal to the Conversion Price, subject as provided in this Section 2.10 (the “Conversion Shares Offer”). The Company may, on behalf of the Conversion Shares Depository, appoint a Conversion Shares Offer Agent to act as placement or other agent to facilitate the Conversion Shares Offer. The Company will deliver a Conversion Shares Offer Notice to the Trustee directly and to the Holders of the Securities through the Clearing Systems within ten (10) Business Days following the Conversion Date specifying whether or not it has elected that a Conversion Shares Offer be conducted. If the Company elects a Conversion Shares Offer to be conducted, the Conversion Shares Offer Period, during which

- 29 -

time the Conversion Shares Offer may be made, shall end no later than forty (40) Business Days following the delivery of the Conversion Shares Offer Notice.

(b) Any Conversion Shares Offer shall be made subject to applicable laws and regulations in effect at the relevant time and shall be conducted, if at all, only to the extent that the Company, in its sole and absolute discretion, determines that the Conversion Shares Offer is practicable. The Company or the purchasers of the Conversion Shares sold in any Conversion Shares Offer shall bear the costs and expenses of any Conversion Shares Offer (with the exception of any stamp duty, stamp duty reserve tax, or any other capital, issue, transfer, registration, financial transaction or documentary tax that may arise or be paid as a consequence of the transfer of Conversion Shares to the Conversion Shares Depository as a consequence of the Conversion Shares Offer), including the fees of the Conversion Shares Offer Agent, if any. If a prospectus or other offering document is required to be prepared in connection with a Conversion Shares Offer, the Company shall facilitate the preparation of such prospectus or other offering document, and the Company and/or its directors shall take responsibility for such prospectus or other offering document, in each case, if and to the extent then required by applicable laws and regulations then in effect. If so requested by the Conversion Shares Depository as offeror, the Company shall indemnify the Conversion Shares Depository for any losses incurred in connection with any Conversion Shares Offer.

(c) Upon completion of the Conversion Shares Offer, the Company or the Conversion Shares Depository shall provide notice to the Holders of the Securities of the composition of the Conversion Shares Offer Consideration (and of the deductions to the Cash Component, if any, of the Conversion Shares Offer Consideration (as set out in the definition of “Conversion Shares Offer Consideration” in Section 1.01)) per £1,000 Tradable Amount of the Securities. The Company reserves the right, in its sole and absolute discretion, to terminate the Conversion Shares Offer at any time during the Conversion Shares Offer Period by providing at least three (3) Business Days’ notice to the Trustee directly and to the Holders of the Securities through the Clearing Systems (or, if the Securities are definitive Securities, by the Company to the Trustee directly and to the Holders at their addresses shown on the Contingent Capital Security Register), and, if it does so, the Company may, in its sole and absolute discretion, take steps (including, without limitation, changing the Suspension Date) to deliver to Holders and Beneficial Owners (or the custodian, nominee, broker or other representative thereof) of the Securities the Conversion Shares at a time that is earlier than the time at which such Holders and Beneficial Owners (or the custodian, nominee, broker or other representative thereof) would have otherwise received the Conversion Shares Offer Consideration, had the Conversion Shares Offer been completed.

(d) If the Company elects, in its sole and absolute discretion, that a Conversion Shares Offer be conducted by the Conversion Shares Depository, each Holder or Beneficial Owner, by subscribing for, purchasing or otherwise acquiring the Securities, shall be deemed to have: (i) irrevocably consented to (x) any Conversion Shares Offer and the Conversion Shares Depository using the Conversion Shares to settle any Conversion Shares Offer in accordance with the terms of the Securities and (y) the transfer of the beneficial interest it holds in the Conversion Shares to the Conversion Shares Depository in connection with the Conversion Shares Offer in accordance with the terms of the Securities, and (ii) irrevocably agreed that (x) the Company, the Conversion Shares Depository and the Conversion Shares Offer

- 30 -

Agent, if any, may take any and all actions necessary to conduct the Conversion Shares Offer in accordance with the terms of the Securities, (y) none of the Company, the Trustee, the Conversion Shares Depository or the Conversion Shares Offer Agent, if any, shall, to the extent permitted by applicable law, incur any liability to the Holders or Beneficial Owners in respect of the Conversion Shares Offer (except for the obligations of the Conversion Shares Depository in respect of the Holders’ and Beneficial Owners’ entitlement to any Conversion Shares Offer Consideration) and (z) each of the Clearing Systems and their respective direct or indirect participants or other intermediary through which it holds such Securities is authorized, directed and requested to take any and all necessary action, if required, to implement the Automatic Conversion (including any related Conversion Shares Offer).

SECTION 2.11. Settlement Procedure.

(a) Delivery of the Conversion Shares or Conversion Shares Offer Consideration, as applicable, to the Holders and Beneficial Owners of the Securities shall be made in accordance with the procedures set forth in this Section 2.11, which remain subject to change to reflect changes in clearing system practices.

(b) The Conversion Shares Offer Notice shall specify the Suspension Date.

(c) On the Suspension Date, the Company shall deliver, to the Trustee directly and to the Holders and of the Securities through the Clearing Systems (or, if the Securities are definitive Securities, by cheque mailed to the Holders at their addresses shown on the Contingent Capital Security Register) a Conversion Shares Settlement Request Notice, pursuant to which the Company shall request that Holders and Beneficial Owners complete a Conversion Shares Settlement Notice and shall specify the Notice Cut-off Date and the Final Cancellation Date.

(d) Holders and Beneficial Owners (or the custodian, nominee, broker or other representative thereof) shall not receive delivery of the relevant Conversion Shares or Conversion Shares Component, as applicable, unless such Holders or Beneficial Owners (or the custodian, nominee, broker or other representative thereof) deliver the applicable Conversion Shares Settlement Notice to the Conversion Shares Depository on or before the Notice Cut-off Date; provided that, if such delivery is made after the end of normal business hours at the specified office of the Conversion Shares Depository, such delivery shall be deemed for all purposes to have been made or given on the next following Business Day.

(e) With respect to any Securities held through the Clearing Systems, the Conversion Shares Settlement Notice must be given in accordance with the respective standard procedures of each of the Clearing Systems (which may include, without limitation, delivery of the notice to the Conversion Shares Depository by electronic means) and in a form acceptable to each of the Clearing Systems and the Conversion Shares Depository. With respect to any definitive Securities, the Conversion Shares Settlement Notice must be delivered to the specified office of the Conversion Shares Depository together with the relevant Securities.

(f) Subject to satisfaction of the requirements and limitations set forth in this Section 2.11 and provided that the Conversion Shares Settlement Notice and the relevant Securities, if applicable, are delivered on or before the Notice Cut-Off Date, the Conversion

- 31 -

Shares Depository shall deliver the relevant Conversion Shares (rounded down to the nearest whole number of Conversion Shares) or Conversion Shares Component (rounded down to the nearest whole number of Conversion Shares), as applicable, to the Holder or Beneficial Owner (or custodian, nominee, broker or other representative thereof) of the relevant Securities completing the relevant Conversion Shares Settlement Notice or its nominee in accordance with the instructions given in such Conversion Shares Settlement Notice on the applicable Settlement Date.

(g) Each Conversion Shares Settlement Notice shall be irrevocable. The Conversion Shares Depository shall determine, in its sole and absolute discretion, whether any Conversion Shares Settlement Notice has been properly completed and delivered, and such determination shall be conclusive and binding on the relevant Holder or Beneficial Owner. If any Holder or Beneficial Owner fails to properly complete and deliver a Conversion Shares Settlement Notice and the relevant Securities, if applicable, the Conversion Shares Depository shall be entitled to treat such Conversion Shares Settlement Notice as null and void.

(h) Neither the Company, nor any member of the Group shall be liable for any stamp duty, stamp duty reserve tax, or any other capital, issue, transfer, registration, financial transaction or documentary tax that may arise or be paid as a consequence of the delivery of Conversion Shares or Conversion Shares Component, as applicable, which tax shall be borne solely by the Holder, Beneficial Owner or, if different, the person to whom the Conversion Shares or that portion, if any, of any Conversion Shares Offer Consideration consisting of Conversion Shares, as applicable, is delivered.

If any Holder or Beneficial Owner (or custodian, nominee, broker or other representative thereof) fails to deliver a Conversion Shares Settlement Notice and the relevant Securities, if applicable, to the Conversion Shares Depository on or before the Notice Cut-off Date, the Conversion Shares Depository shall continue to hold the Conversion Shares or any Conversion Shares Component, as applicable to such Holder or Beneficial Owner, until a Conversion Shares Settlement Notice (and the relevant Securities, if applicable) is so delivered; provided, however,

The Company shall have no liability to any Holder or Beneficial Owner of the Securities for any loss resulting from such Holder’s or Beneficial Owner’s failure to receive any Conversion Shares or Conversion Shares Component of any Conversion Shares Offer Consideration, as applicable, or from any delay in the receipt thereof, in each case as a result of such Holder or Beneficial Owner (or custodian, nominee, broker or other representative thereof) failing to duly submit a Conversion Shares Settlement Notice and the relevant Securities, if applicable, on a timely basis or at all.

- 33 -

(a) Following the occurrence of a Tax Event or a Regulatory Event, the Company may (without any requirement for the consent or approval of the Holders or the Trustee (but subject to the notice requirements described in Section 2.18(b) below)) either substitute all (but not some only) of the Securities for, or vary the terms of the Securities so that they remain or, as appropriate, become, Compliant Securities. Upon the expiry of the notice requirements described in Section 2.18(b) below, the Company shall either substitute or vary the terms of the Securities and, subject to the conditions as set out below, the Trustee shall agree to such substitution or variation; provided that such substitution or variation shall not itself give rise to a right of the Company to redeem the varied or substituted securities.

ARTICLE III

ANTI-DILUTION

SECTION 3.01. Adjustment of Conversion Price. Upon the occurrence of any of the events described below, the Conversion Price shall be adjusted as follows:

(a) If and whenever there shall be a consolidation, reclassification or subdivision in relation to the Ordinary Shares of the Company, the Conversion Price shall be adjusted by multiplying the Conversion Price in effect immediately prior to such consolidation, reclassification or subdivision by the following fraction:

Such adjustment shall become effective on the date the consolidation, reclassification or subdivision, as the case may be, takes effect.

- 34 -

(b) If and whenever the Company shall issue any Ordinary Shares credited as fully paid to the Company’s shareholders as a class by way of capitalization of profits or reserves (including any share premium account or capital redemption reserve) other than (1) where any such Ordinary Shares are or are to be issued instead of the whole or part of a Cash Dividend which the Company’s shareholders would or could otherwise have elected to receive, (2) where the Company’s shareholders may elect to receive a Cash Dividend in lieu of such Ordinary Shares or (3) where any such Ordinary Shares are or are expressed to be issued in lieu of a dividend (whether or not a Cash Dividend equivalent or amount is announced or would otherwise be payable to the Company’s Shareholders, whether at their election or otherwise), the Conversion Price shall be adjusted by multiplying the Conversion Price in effect immediately prior to such issue by the following fraction:

where:

Such adjustment shall become effective on the date of issue of such Ordinary Shares.

(c) If and whenever the Company shall issue any Ordinary Shares to all or substantially all of the Company’s shareholders as a class by way of rights at a price per ordinary share which is less than 95% of the Current Market Price per ordinary share on the Effective Date, the Conversion Price shall be adjusted by multiplying the Conversion Price in effect immediately prior to the Effective Date by the following fraction:

where:

Such adjustment shall become effective on the Effective Date.

- 35 -

For the purpose of any calculation of the consideration receivable or price pursuant to this Section 3.01(c), the following provisions shall apply:

(d) If and whenever the Company shall pay any Extraordinary Dividend to shareholders of the Company as a class, the Conversion Price shall be adjusted by multiplying the Conversion Price in effect immediately prior to the Effective Date by the following fraction:

where:

- 36 -

Such adjustment shall become effective on the Effective Date.

(e) Notwithstanding provisions of Sections 3.01(a)–(d) above:

(i) where the events or circumstances giving rise to any adjustment pursuant to this section have already resulted or will result in an adjustment to the Conversion Price or where the events or circumstances giving rise to any adjustment arise by virtue of any other events or circumstances that have already given or will give rise to an adjustment to the Conversion Price or where more than one event that gives rise to an adjustment to the Conversion Price occurs within such a short period of time that, in the opinion of the Company, a modification to the operation of the adjustment provisions is required to give the intended result, such modification shall be made to the operation of the adjustment provisions as may be determined in good faith by an Independent Financial Adviser to be in its opinion appropriate to give the intended result;

(ii) such modification shall be made to the operation of the Indenture as may be determined in good faith by an Independent Financial Adviser to be in its opinion appropriate to ensure that an adjustment to the Conversion Price or the economic effect thereof shall not be taken into account more than once;

(iii) for the avoidance of doubt, the issue of Ordinary Shares following an Automatic Conversion or upon any conversion or exchange or the exercise of any other options, warrants or other rights shall not result in an adjustment to the Conversion Price;

(iv) in respect of any adjustment pursuant to Sections 3.01(a)-(c) above, such adjustment shall be made only up to the extent it does not result in a Conversion Price that, if applied to the number of relevant Securities at the time of such adjustment, would result in a number of Conversion Shares that constitutes a greater proportion of Conversion Shares as a percentage of the total number of Ordinary Shares issued had the adjustment not been made nor had the corporate event occurred; and

(v) in respect of any adjustment pursuant to Section 3.01(d) above, such adjustment shall be made only up to the extent it does not result in a Conversion Price that, if applied to the number of relevant Securities at the time of such adjustment, would result in the issue of an additional number of Conversion Shares having a value that is greater than the value of the aggregate Extraordinary Dividend which would be attributable to the Ordinary Shares underlying the Securities had such Ordinary Shares been issued.

SECTION 3.02. No Retroactive Adjustments. The Company shall not issue any additional Conversion Shares if the Automatic Conversion occurs after the record date in respect of any consolidation, reclassification or subdivision as described in Section 3.01(a) above, or after the record date or other due date for the establishment of entitlement for any such issue, distribution, grant or offer (as the case may be) as is described in Sections

- 37 -

3.01(b)–(d) above, but before the relevant adjustment to the Conversion Price becomes effective under such Section.

SECTION 3.03. Decision of an Independent Financial Advisor. If any doubt shall arise as to whether an adjustment is required to be made to the Conversion Price or as to the appropriate adjustment to the Conversion Price, and following consultation between the Company and an Independent Financial Adviser, a written opinion of such Independent Financial Adviser in respect thereof is delivered, such written opinion shall be conclusive and binding on the Company, the Trustee and the Holders and Beneficial Owners, save in the case of manifest error.

SECTION 3.04. Rounding Down and Notice of Adjustment to the Conversion Price.

(a) On any adjustment to the Conversion Price as provided under this Article III, if the resultant Conversion Price is a number with more decimal places than the initial Conversion Price, that number shall be rounded to the same number of decimal places as the initial Conversion Price. No adjustment shall be made to the Conversion Price where such adjustment (rounded down if applicable) would be less than 1% of the Conversion Price then in effect. Any adjustment not required to be made, and/or any amount by which the Conversion Price has been rounded down, shall be carried forward and taken into account in any subsequent adjustment, and such subsequent adjustment shall be made on the basis that the adjustment not required to be made had been made at the relevant time and/or, as the case may be, that the relevant rounding down had not been made.

(b) Notice of any adjustments to the Conversion Price shall be given by the Company to Holders via each Clearing System (or, if the Securities are definitive Securities, via the Trustee) promptly after the determination thereof.

(c) The Conversion Price shall not in any event be reduced to below the nominal value of the Ordinary Shares.

SECTION 3.05. Qualifying Takeover Event.

(a) Within ten (10) Business Days following the occurrence of a Takeover Event, the Company shall give notice thereof to the Holders and Beneficial Owners of the Securities by means of a Takeover Event Notice.

(b) If the Takeover Event is a Qualifying Takeover Event, the Securities shall, where the Conversion Date falls on or after the QTE Effective Date, be converted into or exchanged for Approved Entity Shares of the Approved Entity, mutatis mutandis as provided under Section 2.08 above, at a Conversion Price that shall initially be the New Conversion Price, which may be higher or lower than the Conversion Price and references herein to “Conversion Shares” shall be deemed to be references to “Approved Entity Shares.”

(c) The New Conversion Price shall be subject to adjustment in the circumstances provided for under Section 3.01(a) above (if necessary with such modifications and amendments as an Independent Financial Adviser acting in good faith shall determine to be

- 38 -

appropriate and references herein to “Conversion Shares” shall be deemed to be references to “Approved Entity Shares”), and the Company shall give notice to the Holders of the Securities of the New Conversion Price and of any such modifications and amendments thereafter.

(d) In the case of a Qualifying Takeover Event:

(i) the Company shall, to the extent permitted by applicable law and regulation, on or prior to the QTE Effective Date, enter into such agreements and arrangements (including, without limitation supplemental indentures to the Indenture and amendments and modifications to the terms of the Securities and the Indenture) as may be required to ensure that, effective upon the QTE Effective Date, the Securities shall be convertible into, or exchangeable for, Approved Entity Shares, mutatis mutandis in accordance with, and subject to, the provisions of Section 2.08 of this Eleventh Supplemental Indenture, at the New Conversion Price and any references to the Conversion Price shall be construed as references to the New Conversion Price; and

(ii) upon the occurrence of a Capital Adequacy Trigger Event where the Conversion Date falls on or after the QTE Effective Date, the Company shall procure (to the extent within its control) the issue of the relevant number of Approved Entity Shares mutatis mutandis in the manner provided under Section 2.08 of this Eleventh Supplemental Indenture.

(e) The Trustee shall be obliged (at the expense of the Company) to concur with the Company in making any such amendments and modifications to the Indenture, and to execute any supplemental indentures to the Indenture in respect thereof, provided that the Trustee shall not be bound to do so if any such amendments or modifications would, in the opinion of the Trustee, have the effect of (i) exposing the Trustee to any liability against which it is not indemnified and/or secured and/or pre-funded to its satisfaction, (ii) changing, increasing or adding to the obligations or duties of the Trustee or (iii) removing or amending any protection or indemnity afforded to, or any other provision in favor of, the Trustee under the Indenture and/or the terms of the Securities.

(f) For the avoidance of doubt, if for any reason (including, without limitation, because the Acquirer is a Governmental Entity), a Takeover Event is not a Qualifying Takeover Event, there is no provision for any automatic adjustment to the terms of the Securities, whether in the manner provided for in this Article III in respect of Qualifying Takeover Events, or at all, and Section 2.08 shall apply without any automatic adjustment and “Conversion Shares” will continue to have the meaning set out in Section 1.01.

Exhibit A

Form of Global Security

THIS SECURITY IS A GLOBAL REGISTERED SECURITY WITHIN THE MEANING OF THE INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A COMMON DEPOSITARY OR A NOMINEE THEREOF. THIS SECURITY MAY NOT BE EXCHANGED IN WHOLE OR IN PART FOR A SECURITY REGISTERED, AND NO TRANSFER OF THIS SECURITY IN WHOLE OR IN PART MAY BE REGISTERED, IN THE NAME OF ANY PERSON OTHER THAN SUCH COMMON DEPOSITARY OR A NOMINEE THEREOF, EXCEPT IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE.

BY PURCHASING THIS SECURITY, IN THE ABSENCE OF A CHANGE IN LAW OR AN ADMINISTRATIVE OR JUDICIAL RULING TO THE CONTRARY, THE HOLDER AGREES TO CHARACTERIZE THIS SECURITY FOR ALL U.S. FEDERAL INCOME TAX PURPOSES AS PROVIDED ON THE FACE OF THIS SECURITY.

This Security is one of a duly authorized issue of securities of the Company (as defined below) (herein called the “Securities” and each, a “Security”) issued and to be issued in one or more series under and governed by the Contingent Capital Securities Indenture, dated as of August 14, 2018 (as heretofore amended and supplemented, the “Base Indenture”), as supplemented and amended by the Eleventh Supplemental Indenture, dated as of May 15, 2024 (the “Eleventh Supplemental Indenture” and, together with the Base Indenture, the “Indenture”).

The rights of the Holder and Beneficial Owners of this Security are, to the extent and in the manner set forth in Section 12.01 of the Base Indenture and in the subordination provisions of this Security, subordinated to the claims of other creditors of the Company, and this Security is issued subject to the provisions of that Section 12.01 and in the subordination provisions of this Security, and the Holder of this Security, by accepting the same, agrees to, and shall be bound by, such provisions. The provisions of Section 12.01 of the Base Indenture and the terms of this paragraph are governed by, and shall be construed in accordance with, English law.

The rights of the Holder of this Security are subject to Section 2.08 of the Eleventh Supplemental Indenture. Effective upon, and following, the occurrence of the Automatic Conversion, the Holders and Beneficial Owners of the Securities (and any interest therein) prior to the occurrence of such Automatic Conversion shall not have any rights against the Company with respect to repayment of the principal amount of this Security or payment of interest or any other amount in respect of this Security, which liabilities of the Company shall be irrevocably and automatically released, and accordingly the principal amount of this Security shall equal zero at all times thereafter.

Notwithstanding and to the exclusion of any other term of the Securities or any other agreements, arrangements, or understandings between the Company and any Holder or Beneficial Owner of the Securities, or the Trustee on behalf of a Holder or Beneficial Owner, by acquiring the Securities, each Holder and Beneficial Owner of the Securities acknowledges, accepts, agrees to be bound by, and consents to, the exercise of any U.K. Bail-in Power by the Relevant U.K.

A-1

Resolution Authority (as those terms are defined in the Base Indenture) and the provisions set forth in Section 13.01 of the Base Indenture. Upon the exercise of the U.K. Bail-in Power by the Relevant U.K. Resolution Authority with respect to the Securities, the Company shall provide a written notice to the Clearing Systems as soon as practicable regarding such exercise of the U.K. Bail-in Power for purposes of notifying Holders of the Securities of such occurrence. The Company shall also deliver a copy of such notice to the Trustee for information purposes. Any delay or failure by the Company in delivering any notice referred to in this paragraph shall not affect the validity and enforceability of the U.K. Bail-in Power.

Notwithstanding and to the exclusion of any other term of the Securities or any other agreements, arrangements, or understandings between the Company and any Holder or Beneficial Owner of the Securities, or the Trustee on behalf of the Holders of the Securities, by acquiring the Securities, each Holder and Beneficial Owner of the Securities acknowledges, accepts, agrees to be bound by and consents to the determinations made by the Company, the Independent Benchmark Adviser, the Trustee, the Paying Agent, the Calculation Agent or other relevant entities, as applicable, to determine the Subsequent Interest Rate in the event the Company determines that a Benchmark Event has occurred or that there is a Successor Rate, including as may occur without any prior notice from the Company and without the need for the Company to obtain any further consent from Holders and Beneficial Owners of the Securities to implement consequential amendments to the Indenture and other agreements or documents relating to the Securities.

Following the occurrence of a Tax Event or a Regulatory Event, the Company may (without any requirement for the consent or approval of the Holders or the Trustee (but subject to the notice requirements described below)) either substitute all (but not some only) of the Securities for, or vary the terms of the Securities so that they remain or, as appropriate, become, Compliant Securities (as such term is defined in the Eleventh Supplemental Indenture). Upon the expiry of the notice requirements described below, the Company shall either substitute or vary the terms of the Securities and, subject to the conditions as set out below, the Trustee shall agree to such substitution or variation; provided that such substitution or variation shall not itself give rise to a right of the Company to redeem the varied or substituted securities. Any substitution or variation is subject to the Company (i) obtaining the prior consent of the PRA and/or the Relevant U.K. Resolution Authority (in either case if such consent is then required by the Capital Regulations) for such substitution or variation of the Securities and (ii) giving not less than fifteen (15) nor more than sixty (60) days’ prior notice to the Trustee (with a copy to the Paying Agent) and to the Holders, which notice shall be irrevocable, except in the limited circumstances in which a Capital Adequacy Trigger Event and the related Automatic Conversion as described under Section 2.08 of the Eleventh Supplemental Indenture occurs prior to the substitution or variation.

In accordance with Article 14 of the Base Indenture, each Holder and Beneficial Owner that acquires its Securities in the secondary market shall be deemed to acknowledge and agree to be bound by and consent to the same provisions specified in the Indenture to the same extent as the Holders and Beneficial Owners of the Securities that acquire the Securities upon their initial issuance, including, without limitation, with respect to the acknowledgement and agreement to be bound by and consent to the terms of the Securities, including in relation to interest cancellation, Automatic Conversion, the Conversion Shares Offer, the U.K. Bail-in Power and the limitations on remedies specified in this Security and Article V of the Base Indenture.

BARCLAYS PLC

8.500% Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities

BARCLAYS PLC, a company duly incorporated and existing under the laws of England and Wales (herein called the “Company”, which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay The Bank of New York Mellon Depository (Nominees) Limited, or registered assigns, the principal sum of £[•] ([•] POUNDS STERLING), if and to the extent due, and to pay interest thereon, if any, in accordance with the terms hereof and the Indenture.

The Securities shall have no fixed maturity or fixed redemption date. From (and including) the Issue Date to (but excluding) December 15, 2030, the interest rate on the Securities shall be 8.500% per annum (the “Initial Interest Rate”). From and including December 15, 2030 and each fifth anniversary date thereafter, commencing December 15, 2030 (each such date, a “Reset Date”) to (but excluding) the next following Reset Date (each such period, a “Reset Period”), the applicable per annum interest rate (the “Subsequent Interest Rate”) will, subject to Section 2.02(b) and Section 2.02(d) of the Eleventh Supplemental Indenture, be equal to the sum, as determined by the Calculation Agent, of the applicable Mid-Market Swap Rate on the relevant Reset Determination Date and 4.881% (the “Margin”), converted to a quarterly rate in accordance with market convention as instructed by the Company (rounded to three decimal places, with 0.0005 rounded down). Each Subsequent Interest Rate shall be determined in compliance with the relevant Capital Regulations. Subject to the provisions on the reverse of this Security relating to cancellation and deemed cancellation of interest and to Sections 3.12 and 3.13 of the Base Indenture and to the following sentence, interest, if any, shall be payable in four equal quarterly installments in arrear on March 15, June 15, September 15 and December 15 of each year (each, an “Interest Payment Date”). The first date on which interest may be paid will be September 15, 2024 for the period commencing on (and including) May 15, 2024 and ending (but excluding) September 15, 2024 (and thus a long first interest period). If a date of redemption is not a Business Day, the Company may pay interest (if any) and principal on the next Business Day, but interest on that payment will not accrue during the period from and after the date of redemption.

“Five-year Mid-Market Swap Rate Quotations” means, for any Reset Period, the arithmetic mean of the bid and offered rates for the annual fixed leg (calculated on an Actual/365 (Fixed) day count basis) of a fixed-for-floating sterling interest rate swap transaction which: (i) has a term of five years commencing on the applicable Reset Date; (ii) is in an amount that is representative of a single transaction in the relevant market at the relevant time with an acknowledged dealer of good credit in the swap market; and (iii) has a floating leg based on the overnight SONIA rate compounded for 12-months (calculated on an Actual/365 (Fixed) day count basis).

“Mid-Market Swap Rate” means, in relation to a Reset Date and the related Reset

A-3

Determination Date:

“Reference Banks” means four major banks in the sterling swap, money, securities or other market most closely connected with the relevant Mid-Market Swap Rate, as selected by the Company on the advice of an investment bank of international repute.

“Reset Reference Bank Rate” means, in relation to a Reset Date and the related Reset Determination Date, the percentage rate determined by the Calculation Agent on the basis of the Five-year Mid-Market Swap Rate Quotations provided by each of the Reference Banks at approximately 11:00 a.m. (London time) on the relevant Reset Determination Date (or thereafter on such date), rounded, if necessary, to the nearest 0.001 per cent. (with 0.0005 per cent. being rounded upwards). If at least three Five-year Mid-Market Swap Rate Quotations are provided, the Reset Reference Bank Rate will be the arithmetic mean of such Five-year Mid-Market Swap Rate Quotations, eliminating the highest quotation (or, in the event of equality, one of the highest) and the lowest quotation (or, in the event of equality, one of the lowest). If only two Five-year Mid-Market Swap Rate Quotations are provided, the Reset Reference Bank Rate will be the arithmetic mean of such Five-year Mid-Market Swap Rate Quotations. If only one Five-year Mid-Market Swap Rate Quotation is provided, the Reset Reference Bank Rate will be the quotation provided. If no Five-year Mid-Market Swap Rate Quotations are provided, the Reset Reference Bank Rate will be (i) in respect of the Reset Reference Bank Rate determined in respect of the Reset Date falling on December 15, 2030, 3.997 per cent. per annum or (ii) in respect of the Reset Reference Bank Rate determined in respect of any Reset Date other than December 15, 2030, the Mid-Market Swap Rate in respect of the immediately preceding Reset Date.

In addition to and notwithstanding the provisions above, if the Company determines that a Benchmark Event has occurred or that there is a Successor Rate, in either case when any Subsequent Interest Rate (or the relevant component part thereof) remains to be determined by reference to the Reference Rate, then the Company may elect (acting in good faith

A-4

and in a commercially reasonable manner) to apply the following provisions:

A-5

provided that the determination of any Successor Rate or Alternative Reference Rate or Adjustment Spread, and any other related changes to the Securities, shall be made in accordance with the relevant Capital Regulations (if applicable) and shall not prejudice the then current capital or eligible liabilities qualification of the Securities, as applicable, in each case for the purposes of and in accordance with the Capital Regulations. None of the Trustee, the Paying Agent, any other paying agent or the Calculation Agent shall have any duty to determine whether a Benchmark Event has occurred or that there is a Successor Rate.

If any Interest Payment Date is not a Business Day, the Interest Payment Date shall be postponed to the next Business Day, and no further interest or other payment shall be owed or made in respect of such delay.

A-6

Subject to Sections 3.12 and 3.13 of the Base Indenture, interest on the Securities, if any, will be computed and payable as follows:

(a) if the Calculation Period is equal to or shorter than the Regular Period during which it falls, interest on the Securities, if any, will be computed and payable on the basis of the number of days in the Calculation Period, divided by the product of (1) the number of days in the Regular Period in which the Calculation Period falls and (2) four; or

(b) if the Calculation Period is longer than one Regular Period, interest on the Securities, if any, will be computed and payable on the basis of the sum of: (A) the number of days in such Calculation Period falling in the Regular Period in which it begins divided by the product of (1) the number of days in such Regular Period and (2) four; and (B) the number of days in such Calculation Period falling in the next Regular Period divided by the product of (1) the number of days in such Regular Period and (2) four.

The interest, if any, so payable, and paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest which shall be the close of business on the Business Day immediately preceding each Interest Payment Date (whether or not a Business Day).

In addition to any other restrictions on payments of principal and interest contained in the Indenture, no repayment of the principal amount of the Securities or payment of interest on the Securities shall become due and payable after the exercise of any U.K. Bail-in Power by the Relevant U.K. Resolution Authority unless such repayment or payment would be permitted to be made by the Company under the laws and regulations of the United Kingdom and the European Union applicable to the Company.

Interest on the Securities shall be due and payable only at the sole discretion of the Company, and the Company shall have sole and absolute discretion at all times and for any reason to cancel (in whole or in part) any interest payment that would otherwise be payable on any Interest Payment Date. If the Company does not make an interest payment in respect of the Securities on the relevant Interest Payment Date (or if the Company elects to make a payment of a portion, but not all, of such interest payment), such non-payment shall evidence the Company’s exercise of its discretion to cancel such interest payment (or the portion of such interest payment not paid), and accordingly such interest payment (or the portion thereof not paid) shall not be due and payable. If the Company provides notice to cancel a portion, but not all, of an interest payment in respect of the Securities, and the Company subsequently does not make a payment of the remaining portion of such interest payment on the relevant Interest Payment Date, such non-payment shall evidence the Company’s exercise of its discretion to cancel such remaining portion of such interest payment, and accordingly such remaining portion of the interest payment shall also not be due and payable.

Interest shall only be due and payable on an Interest Payment Date to the extent it is not cancelled or deemed cancelled (in each case, in whole or in part) in accordance with the terms of this Security, and any interest cancelled or deemed cancelled (in each case, in whole or in part) pursuant to this Security shall not be due and shall not accumulate or be payable at any

A-7

time thereafter, and Holders and Beneficial Owners of the Securities shall have no rights thereto or to receive any additional interest or compensation as a result of such cancellation or deemed cancellation.

Without limitation on the foregoing paragraph and subject to the extent permitted by the following sentence in respect of partial interest payments in respect of the Securities, the Company shall not make an interest payment in respect of the Securities on any Interest Payment Date (and such interest payment shall therefore be deemed to have been cancelled and thus shall not be due and payable on such Interest Payment Date) if either (a) the Company has an amount of Distributable Items on such Interest Payment Date that is less than the sum of (i) all distributions or interest payments made or declared by the Company since the end of the last financial year and prior to such Interest Payment Date on or in respect of any Parity Securities, the Securities and any Junior Securities plus (ii) all distributions or interest payments payable by the Company (and not cancelled or deemed cancelled) on such Interest Payment Date (x) on the Securities and (y) on or in respect of any Parity Securities, in the case of each of (i) and (ii), excluding any payments already accounted for in determining the Distributable Items; or (b) the Solvency Condition is not satisfied in respect of such interest payment. The Company may, in its sole discretion, elect to make a partial interest payment in respect of the Securities on any Interest Payment Date, only to the extent that such partial interest payment may be made without breaching the restrictions of this paragraph. Any interest cancelled pursuant to this paragraph shall be “deemed cancelled” under the terms of this Security and the Indenture and shall not be due and payable. Neither the Trustee nor any agent of the Trustee shall be required to monitor compliance with the restriction on interest payments contained in this paragraph or to perform any calculations in connection therewith.

By subscribing for, purchasing or other acquiring the Securities, each Holder and each Beneficial Owner shall be deemed to have contracted and agreed that (i) interest is payable solely at the discretion of the Company, and no amount of interest shall become due and payable in respect of the relevant interest period to the extent that it has been (x) cancelled (in whole or in part) by the Company at the Company’s sole discretion and/or (y) deemed cancelled (in whole or in part) as a result of the Company’s having insufficient Distributable Items or failing to satisfy the Solvency Condition; and (ii) a cancellation or deemed cancellation of interest (in each case, in whole or in part) in accordance with the terms of the Indenture shall not constitute a default in payment or otherwise under the terms of the Securities or the Indenture. Interest on the Securities shall only be due and payable on an interest payment date to the extent it is not cancelled or deemed cancelled under the terms of this Security and Sections 3.12 and 3.13 of the Base Indenture. Any interest cancelled or deemed cancelled (in each case, in whole or in part) in the circumstances described in this Security shall not be due and shall not accumulate or be payable at any time thereafter, and Holders and Beneficial Owners of the Securities shall have no rights thereto or to receive any additional interest or compensation as a result of such cancellation or deemed cancellation of interest in respect of the Securities.

Payments of principal of and interest, if any, on the Securities shall be made in such coin or currency of the United Kingdom as at the time of payment is legal tender for payment of public and private debts and such payments shall be made through one or more Paying Agents appointed under the Base Indenture to the Holder or Holders of this Security. Initially, the Paying Agent for the Securities shall be The Bank of New York Mellon, London

A-8

Branch, 160 Queen Victoria Street, London EC4V 4LA, United Kingdom, and the Contingent Capital Security Registrar shall be The Bank of New York Mellon SA/NV, Luxembourg Branch, 2-4 Rue Eugene Ruppert, Vertigo Building – Polaris, Luxembourg, L-2453, Luxembourg. The Company may change the Paying Agent or the Contingent Capital Security Registrar without prior notice to the Holders of the Securities, and in such an event the Company may act as Paying Agent or Contingent Capital Security Registrar. Payments of principal of and interest on the Securities shall be made by wire transfer of immediately available funds; provided, however, that in the case of payments of principal, this Security is first surrendered to the Paying Agent.

This Security shall be governed by and construed in accordance with the laws of the State of New York, except for the subordination provisions referred to herein and set forth in Section 12.01 of Base Indenture, and the waiver of set-off provisions referred to herein and set forth in Section 5.04(d) of the Base Indenture, which are governed by, and construed in accordance with, English law.

Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture, as defined herein.

THIS SECURITY IS NOT A DEPOSIT LIABILITY OF BARCLAYS PLC AND IS NOT COVERED BY THE UNITED KINGDOM FINANCIAL SERVICES COMPENSATION SCHEME OR INSURED BY THE UNITED STATES FEDERAL DEPOSIT INSURANCE CORPORATION, THE CANADA DEPOSIT INSURANCE CORPORATION OR ANY OTHER GOVERNMENTAL AGENCY OF THE UNITED STATES, THE UNITED KINGDOM, CANADA OR ANY OTHER JURISDICTION.

Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof, directly or through an Authenticating Agent, by manual, facsimile or electronic signature of an authorized signatory, this Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

By purchasing this Security, the Holder of this Security agrees (in the absence of a statutory, regulatory, administrative or judicial ruling to the contrary) to treat this Security as equity of the Company for U.S. federal income tax purposes.

(Reverse of Security)

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities” and each, a “Security”) issued and to be issued in one or more series under and governed by the Contingent Capital Securities Indenture, dated as of August 14, 2018 (as heretofore amended and supplemented, the “Base Indenture”), among the Company, The Bank of New York Mellon, London Branch, as trustee (herein called the “Trustee,” which term includes any successor trustee under the Base Indenture) and The Bank of New York Mellon SA/NV, Luxembourg Branch, as contingent capital security registrar, as supplemented and amended by the Eleventh Supplemental Indenture, dated as of May 15, 2024 (the “Eleventh Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), and reference is hereby made to the Indenture, the terms of which are incorporated herein by reference, for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee, the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. Insofar as the provisions of the Indenture may conflict with the provisions set forth in this Security, the former shall control for purposes of this Security. All terms used in this Security that are defined in the Indenture and not otherwise defined herein shall have the meanings assigned to them in the Indenture.

This Security is one of the series designated on the face hereof, limited to an aggregate principal amount of £1,250,000,000, which amount may be increased at the option of the Company if in the future it determines that it may wish to sell additional Securities of this series. References herein to “this series” mean the series designated on the face hereof.

Any amounts to be paid by the Company on the Securities shall be made without deduction or withholding for, or on account of, any and all present or future income, stamp and other taxes, levies, imposts, duties, charges, fees, deductions or withholdings (“Taxes”) now or hereafter imposed, levied, collected, withheld or assessed by, or on behalf of, the United Kingdom or any political subdivision of the United Kingdom or authority thereof or therein having the power to tax (each a “Taxing Jurisdiction”), unless such deduction or withholding is required by law. If any such Taxes shall at any time be required by a Taxing Jurisdiction to be deducted or withheld, the Company shall, subject to the exceptions and limitations set forth in Section 10.04 of the Base Indenture and Section 12.01 of the Base Indenture, pay such additional amounts of, or in respect of, any interest (but not principal or any premium) on the Securities (“Additional Amounts”) as may be necessary in order that the net amounts in respect of interest paid to the Holders of the Securities, after such deduction or withholding, shall equal the amounts in respect of interest that would have been payable in respect of such Securities had no such deduction or withholding been required.

Any amounts to be paid by the Company or the Paying Agent on the Securities shall be paid net of any deduction or withholding imposed or required pursuant to Sections 1471 through 1474 of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), any current or future regulations or official interpretations thereof, any agreement entered into pursuant to Section 1471(b) of the Code, or any fiscal or regulatory legislation, rules or practices adopted pursuant to any intergovernmental agreement entered into in connection with the implementation of such Sections of the Code (or any law implementing such an intergovernmental agreement) (a “FATCA Withholding Tax”), and neither the Company nor the Paying Agent shall be required to

A-11

pay Additional Amounts on account of any FATCA Withholding Tax.

Any Paying Agent shall be entitled to make a deduction or withholding from any payment which it makes under the Securities and the Indenture for or on account of (i) any present or future taxes, duties or charges if and to the extent so required by any applicable law and (ii) any FATCA Withholding Tax (together, “Applicable Law”). In either case, the Paying Agent shall make any payment after a deduction or withholding has been made pursuant to Applicable Law and shall report to the relevant authorities the amount so deducted or withheld. However, such deduction or withholding will not apply to payments made under the Securities and the Indenture through the relevant clearing systems. In all cases, the Paying Agent shall have no obligation to gross up any payment made subject to any deduction or withholding pursuant to Applicable Law. In addition, amounts deducted or withheld by the Paying Agent as described in this paragraph will be treated as paid to the Holder of the Securities, and the Company will not pay Additional Amounts in respect of such deduction or withholding, except to the extent the provisions in this paragraph explicitly provide otherwise. The restrictions on interest payments described on the face of this Security apply to any Additional Amounts mutatis mutandis.

The Company agrees, to the extent the Company has actual knowledge of such information, to provide the Paying Agent with sufficient information about any modification to the terms of the Securities for the purposes of determining whether FATCA Withholding Tax applies to any payment of principal or interest on the Securities.

Subject to the limitations specified below, the Company may, at the Company’s option, redeem the Securities, in whole but not in part, on any day falling in the period commencing on (and including) June 15, 2030 and ending on (and including) the first Reset Date or on any day falling in the period commencing on (and including) the date that is six months before any subsequent Reset Date and ending on (and including) such Reset Date at a redemption price equal to 100% of the principal amount of the Securities then Outstanding, together with any accrued but unpaid interest (which excludes any interest cancelled or deemed cancelled as specified below) to (but excluding) the date fixed for redemption.

Subject to the limitations specified below, the Company may also, at any time, at the Company’s option, redeem the Securities, in whole but not in part pursuant to Section 2.05 of the Eleventh Supplemental Indenture and/or Section 11.12 of the Base Indenture.

Subject to the limitations specified below, if, at any time from the fifth anniversary of the Issue Date (unless otherwise permitted by the PRA), the outstanding aggregate principal amount of the Securities is 25% or less of the aggregate principal amount of the Securities originally issued (and, for these purposes, any additional securities issued as set out under Section 2.01(c) of the Eleventh Supplemental Indenture shall be deemed to have been originally issued), the Company may redeem all (but not some only) of the Outstanding Securities at a redemption price equal to 100% of their principal amount, together with any accrued but unpaid interest (which excludes any interest cancelled or deemed cancelled as specified below) to (but excluding) the date fixed for redemption.

Any interest payments that have been cancelled or deemed cancelled pursuant to the terms of this Security and the Indenture shall not be payable if the Securities are redeemed

A-12

pursuant to any of the three preceding paragraphs.

Before the Company may redeem the Securities pursuant to any of the preceding paragraphs relating to the Company’s rights of redemption, the Company shall deliver prior notice of not less than fifteen (15) days, nor more than sixty (60) days to the Holders of the Securities pursuant to Section 2.07 of the Eleventh Supplemental Indenture.

Notwithstanding any other provision of this Security or the Eleventh Supplemental Indenture, the Company may redeem the Securities at the Company’s option only subject to the limitations specified in Section 11.08 and Section 11.13 of the Base Indenture.

Subject to Sections 11.10 and 11.13 of the Base Indenture, the Company or any member of the Group may purchase or otherwise acquire any of the Outstanding Securities at any price in the open market or otherwise in accordance with the Capital Regulations, and subject to the prior consent of the PRA and/or the Relevant U.K. Resolution Authority (in either case if such consent is then required by the Capital Regulations) and to applicable law and regulation.

An Automatic Conversion shall occur without delay upon the occurrence of a Capital Adequacy Trigger Event as set forth in Section 2.08 of the Eleventh Supplemental Indenture.

The Conversion Price shall be subject to adjustment as provided in Article III of the Eleventh Supplemental Indenture.

The Company may, in its sole and absolute discretion, following the occurrence of an Automatic Conversion and no later than 10 (ten) Business Days following the Conversion Date, elect that the Conversion Shares Depository make an offer of all or some of the Conversion Shares to all or some of the Company’s ordinary shareholders at a cash price per Conversion Share equal to the Conversion Price, as set forth in and subject to the provisions of Section 2.10 of the Eleventh Supplemental Indenture.

This Security is subject to the provisions regarding the U.K. Bail-in Power Acknowledgement set forth in Section 13.01 of the Base Indenture.

This Security is subject to the substitution and variation provisions set forth in Section 2.18 of the Eleventh Supplemental Indenture.

If a Winding-Up Event occurs before the occurrence of a Capital Adequacy Trigger Event, subject to the subordination provisions of Section 12.01 of the Base Indenture, the outstanding principal amount of this Security shall become immediately due and payable, without the need of any further action on the part of the Trustee, the Holders or any other Person.

A “Winding-Up Event” shall result if (i) a court of competent jurisdiction in England (or such other jurisdiction in which the Company may be organized) makes an order for the winding-up of the Company which is not successfully appealed within thirty (30) days of the making of such order, (ii) the Shareholders of the Company adopt an effective resolution for the winding-up of the Company (other than, in the case of either (i) or (ii) above, under or in

A-13

connection with a scheme of reconstruction, merger or amalgamation not involving a bankruptcy or insolvency) or (iii) following the appointment of an administrator of the Company, the administrator gives notice that it intends to declare and distribute a dividend.

If the Company fails to pay any amount that has become due and payable under this Security and such failure continues for fourteen (14) days, the Trustee may provide a written notice of such failure to the Company. If within a period of fourteen (14) days following the provision of such notice, the failure continues and has not been cured nor waived (a “Non-Payment Event”), the Trustee may, at its discretion, and without further notice to the Company, institute proceedings in England (or such other jurisdiction in which the Company may be organized) (but not elsewhere) for the winding-up of the Company and/or prove in a winding-up of the Company and/or claim in a liquidation or administration of the Company. For the avoidance of doubt, if, pursuant to this Security and Sections 3.12 and 3.13 of the Base Indenture, the Company cancels any interest payment on any Interest Payment Date or if such interest payment is deemed cancelled (in each case, in whole or in part), then such interest payment shall not be due and payable in respect of such Interest Payment Date, and no Non-Payment Event under the Securities will occur or be deemed to have occurred as a result of such cancellation or deemed cancellation (in each case, in whole or in part).

In addition to the remedies for a Non-Payment Event provided in the paragraph above, the Trustee, may without further notice, institute such proceedings against the Company as the Trustee may deem fit to enforce any term, obligation or condition binding upon the Company under the Securities or the Indenture (other than any payment obligation of the Company under or arising from the Securities or the Indenture, including, without limitation, payment of any principal or interest) (such obligation, a “Performance Obligation”), provided always that the Trustee (acting on behalf of the Holders and Beneficial Owners of the Securities) and the Holders and Beneficial Owners of the Securities may not enforce, and may not be entitled to enforce or otherwise claim, against the Company any judgment or other award given in such proceedings that requires the payment of money by the Company, whether by way of damages or otherwise (a “Monetary Judgment”), except by proving such Monetary Judgment in a winding-up of the Company and/or by claiming such Monetary Judgment in an administration of the Company. For the avoidance of doubt, the sole and exclusive manner by which the Trustee (acting on behalf of the Holders and Beneficial Owners of the Securities) and the Holders and Beneficial Owners of the Securities may seek to enforce or otherwise claim a Monetary Judgment against the Company in connection with the Company’s breach of a Performance Obligation shall be by proving such Monetary Judgment in a winding-up of the Company and/or by claiming such Monetary Judgment in an administration of the Company. By its acquisition of the Securities, each Holder and Beneficial Owner of the Securities acknowledges and agrees that such Holder and Beneficial Owner shall not seek to enforce or otherwise claim, and will not direct the Trustee (acting on behalf of the Holders and Beneficial Owners of the Securities) to enforce or otherwise claim, a Monetary Judgment against the Company in connection with the Company’s breach of a Performance Obligation, except by proving such Monetary Judgment in a winding-up of the Company and/or by claiming such Monetary Judgment in an administration of the Company.

Other than the limited remedies specified in this Security and Article V of the Base Indenture, and subject to the second paragraph below, no remedy against the Company

A-14

shall be available to the Trustee (acting on behalf of the Holders and Beneficial Owners of the Securities) and to the Holders and Beneficial Owners, whether for the recovery of amounts owing in respect of the Securities or under the Indenture, or in respect of any breach by the Company of any of the Company’s obligations under or in respect of the terms of such Securities or under the Indenture in relation thereto; provided, however, that the Company’s obligations to the Trustee under Section 6.07 of the Base Indenture and the Trustee’s rights to have money collected applied first to pay amounts due to it under such Section pursuant to Section 5.07 of the Base Indenture expressly survive any such Default and are not subject to the subordination provisions of Section 12.01 of the Base Indenture.

In the case of a Default under this Security, the Trustee shall exercise such of the rights and powers vested in it by the Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs. A “Default” shall occur upon (i) the occurrence of a Winding-Up Event that occurs before the occurrence of a Capital Adequacy Trigger Event or (ii) the occurrence of a Non-Payment Event or (iii) a breach by the Company of a Performance Obligation.

Notwithstanding the limitations on remedies specified in this Security and under Article V of the Base Indenture, (1) the Trustee shall have such powers as are required to be authorized to it under the Trust Indenture Act in respect of the rights of the Holders and Beneficial Owners of the Securities under the provisions of the Indenture, and (2) nothing shall impair the right of a Holder or Beneficial Owner of the Securities under the Trust Indenture Act, absent such Holder’s or Beneficial Owner’s consent, to sue for any payment due but unpaid with respect to the Securities; provided that, in the case of (1) and (2) above, any payments in respect of, or arising from, the Securities, including any payments or amounts resulting or arising from the enforcement of any rights under the Trust Indenture Act in respect of the Securities, shall be subject to the subordination provisions set forth in Section 12.01 of the Base Indenture. Subject to the provisions of the Trust Indenture Act, no Holder shall be entitled to proceed directly against the Company except as set forth in Section 5.08 of the Base Indenture.

The Securities shall constitute the Company’s direct, unsecured and subordinated obligations, ranking pari passu without any preference among themselves. In the event of a winding up or administration of the Company, the rights and claims of the Holders and Beneficial Owners of the Securities in respect of or arising from the Securities (including any damages (if payable)) shall be subordinated to the claims of Senior Creditors. If (a) an order is made, or an effective resolution is passed, for the winding-up of the Company (except in any such case for a solvent winding-up solely for the purpose of a merger, reconstruction or amalgamation); or (b) following the appointment of an administrator of the Company, the administrator gives notice that it intends to declare and distribute a dividend, then (1) if such events specified in (a) or (b) above occur prior to the date on which a Capital Adequacy Trigger Event occurs, there shall be payable by the Company in respect of each Security (in lieu of any other payment by the Company), such amount, if any, as would have been payable to a Holder of Securities if, on the day prior to the commencement of the winding-up or such administration and thereafter, such Holder of Securities were the holder of the most senior class of preference shares in the capital of the Company, having an equal right to a return of assets in the winding-up or such administration to, and so ranking pari passu with, the holders of such class of preference shares (if any) from time to time issued by the Company that has a preferential right to a return

A-15

of assets in the winding-up or such administration, and so ranking ahead of the holders of all other classes of issued shares for the time being in the capital of the Company, but ranking junior to the claims of Senior Creditors, and on the assumption that the amount that such Holder of Securities was entitled to receive in respect of such preference shares, on a return of assets in such winding-up or such administration, was an amount equal to the principal amount of the relevant Security, together with any damages (if payable), and (2) if such events specified in (a) or (b) above occur on or after the date on which a Capital Adequacy Trigger Event occurs but prior to the Conversion Date, then for purposes of determining the claim of a Holder of the Securities in such winding-up or such administration, the Conversion Date in respect of an Automatic Conversion shall be deemed to have occurred immediately prior to the occurrence of such events specified in (a) or (b) above. Other than in the event of a winding-up or administration of the Company as described in this paragraph, payments in respect of or arising from the Securities shall be conditional (i) upon the Company’s being solvent at the time of payment by the Company, and (ii) in that no sum in respect of or arising from the Securities may fall due and be paid except to the extent that the Company could make such payment and still be solvent immediately thereafter (such condition referred to herein as the “Solvency Condition”). For purposes of determining whether the Solvency Condition is met, the Company shall be considered to be solvent at a particular point in time if (x) it is able to pay its debts owed to Senior Creditors as they fall due and (y) the Balance Sheet Condition has been met. An Officer’s Certificate executed in accordance with the Indenture as to the Company’s solvency at any particular point in time shall be treated by the Company, the Trustee, the Holders, the Beneficial Owners and all other interested parties as correct and sufficient evidence thereof. “Senior Creditors” means creditors of the Company (aa) who are unsubordinated creditors; (bb) whose claims are, or are expressed to be, subordinated (whether only in the event of the winding-up or administration of the Company or otherwise) to the claims of unsubordinated creditors of the Company but not further or otherwise; (cc) who are creditors in respect of any secondary non-preferential debt (“secondary non-preferential debts” shall have the meaning given to it in the U.K. Insolvency Act 1986, as amended or replaced from time to time); or (dd) whose claims are, or are expressed to be, junior to the claims of other creditors of the Company, whether subordinated or unsubordinated, other than those whose claims rank, or are expressed to rank, pari passu with, or junior to, the claims of the Holders of the Securities. The “Balance Sheet Condition” shall be satisfied in relation to the Company if the value of its assets is at least equal to the value of its liabilities (taking into account its contingent and prospective liabilities), according to the criteria that would be applied by the High Court of Justice of England and Wales (or the relevant authority of such other jurisdiction in which the Company may be organized) in determining whether the Company is “unable to pay its debts” under section 123(2) of the U.K. Insolvency Act 1986 or any amendment or re-enactment thereof (or in accordance with the corresponding provisions of the applicable laws of such other jurisdiction in which the Company may be organized). Any payment of interest not due by reason of the provisions contained in this paragraph shall be deemed canceled pursuant to the terms of this Security and Section 3.13 of the Base Indenture.

Subject to applicable law, no Holder of Securities may exercise, claim or plead any right of set-off, compensation, counterclaim, retention or netting in respect of any amount owed to it by the Company arising under, or in connection with, the Securities and each Holder of Securities shall, by virtue of its holding of any Securities (or any beneficial interest therein), be deemed, to the fullest extent permitted under applicable law, to have waived all such rights of

A-16

set-off, compensation, counterclaim, retention and netting. Notwithstanding the foregoing, if any amounts due and payable to any Holder of this Security by the Company in respect of, or arising under, this Security are discharged by set-off, compensation, counterclaim, retention or netting, such Holder shall, subject to applicable law, immediately pay an amount equal to the amount of such discharge to the Company (or, in the event of its winding-up or administration, the liquidator or administrator of the Company, as the case may be) and, until such time as payment is made, shall hold an amount equal to such amount in trust for the Company (or the liquidator or administrator of the Company, as the case may be) and, accordingly, any such discharge shall be deemed not to have taken place. By its acquisition of the Securities, each Holder and Beneficial Owner agrees to be bound by these provisions relating to waiver of set-off, compensation, counterclaim, retention and netting.

The Indenture permits, with certain exceptions and subject to certain conditions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a specified majority in principal amount of the Securities then Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of the Securities of each series then Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past Defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have any right to institute any proceeding, judicial or otherwise, with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Default with respect to the Securities of this series, the Holders of not less than 25% in aggregate principal amount of the Securities of this series then Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Default as Trustee and offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities to be incurred in compliance with such request, the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series then Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for sixty (60) days after receipt of such notice, request and offer of security or indemnity, and, in the case of a proceeding in England (or such other jurisdiction in which the Company may be organized) (but not elsewhere) for the winding-up of the Company, such proceeding is in the name and on behalf of the Trustee to the same extent (but no further or otherwise) as the Trustee would have been entitled so to do.

Notwithstanding any contrary provisions in this Security, nothing shall impair the right of a Holder of this Security under the Trust Indenture Act, absent such Holder’s consent, to sue for any payments due but unpaid with respect to this Security.

A-17

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Contingent Capital Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of this Security is payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Contingent Capital Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing. Thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

This Security, and any other Securities of this series and of like tenor, are issuable only in registered form without coupons in initial denominations of £200,000 and increments of £1,000 thereafter. The denominations cannot be changed without the consent of the Trustee. The denomination of each interest in this Security shall be the “Tradable Amount” of such book-entry interest. Prior to an Automatic Conversion, the aggregate Tradable Amount of the interests in this Security shall equal this Security’s outstanding principal amount. Following an Automatic Conversion, the principal amount of this Security shall equal zero, but the Tradable Amount of the book-entry interests in this Security shall remain unchanged as a result of the Automatic Conversion.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

This Security shall be governed by and construed in accordance with the laws of the State of New York, except for the subordination provisions referred to herein and set forth in Section 12.01 of the Base Indenture, and the waiver of set-off provisions referred to herein and set forth in Section 5.04(d) of the Base Indenture, which are governed by, and construed in accordance with, English law.

This notice is in relation to Barclays PLC’s (the “Company”) £1,250,000,000 8.500% Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities (ISIN: XS2813323503) issued on May 15, 2024 (the “Securities”) pursuant to the Contingent Capital Securities Indenture, dated August 14, 2018, as amended and supplemented from time to time, among the Company, The Bank of New York Mellon, London Branch, as Trustee (the “Trustee”) and Paying Agent (the “Paying Agent”) and The Bank of New York Mellon SA/NV, Luxembourg Branch, as Contingent Capital Security Registrar (the “Registrar”), as further supplemented and amended by the Eleventh Supplemental Indenture, dated May 15, 2024, among the Company, the Trustee, the Paying Agent and the Registrar (together, the “Indenture”), and pursuant to the prospectus supplement dated May 8, 2024 supplementing the prospectus dated March 1, 2024. Capitalized terms used herein and not defined herein shall have the respective meanings ascribed to such terms in the Indenture.

Barclays PLC hereby notifies Clearstream, Luxembourg and Euroclear (the “Clearing Systems”), the Holders and Beneficial Owners of the Securities that a Capital Adequacy Trigger Event has occurred with respect to the Securities. Such Capital Adequacy Trigger Event has occurred because the Group’s Fully Loaded CET1 Ratio as of [Date], as determined by Barclays PLC on a consolidated basis in accordance with the Capital Regulations applicable to the Group on such date, was less than 7.00%.

B-1

Upon the occurrence of the Capital Adequacy Trigger Event, the terms of the Securities provide for an Automatic Conversion of the Securities on the Conversion Date, which [was] [is expected to be] [Date], based on the Conversion Price, which is [Price]. ² Upon the Automatic Conversion, all of Barclays PLC’s obligations under the Securities (other than with respect to the CSO Obligations, if any) shall be irrevocably and automatically released in consideration of Barclays PLC’s issuance of ordinary shares of Barclays PLC (the “Conversion Shares”) to the Conversion Shares Depository (or other relevant recipient). However, the terms of the Securities provide that the Securities shall remain in existence until the applicable Settlement Date for the sole purpose of evidencing (a) a right to receive Conversion Shares or Conversion Shares Offer Consideration, as applicable, from the Conversion Shares Depository and (b) the Company’s CSO Obligations, if any.

In addition, the terms of the Securities provide that Barclays PLC may, in its sole and absolute discretion, elect that a Conversion Shares Offer be conducted, no later than ten (10) Business Days of the Conversion Date. Barclays PLC will deliver to each of the Clearing Systems, the Holders and the Beneficial Owners a Conversion Shares Offer Notice specifying, among other things, whether or not Barclays PLC has elected that a Conversion Shares Offer be conducted and the Suspension Date. The Securities may continue to trade until the Suspension Date.

Accordingly, Barclays PLC hereby instructs each of the Clearing Systems to indicate to all participants that payments of principal and interest are no longer payable under the Securities as of the Conversion Date and that the Securities will have no further entitlement to interest or principal as of such date by making a note to that effect in its systems.

Barclays PLC

London E14 5HP

Ladies and Gentlemen:

We have acted as special U.S. counsel to Barclays PLC, a public limited company incorporated under the law of England and Wales (the “Company”), in connection with the Company’s offering pursuant to a registration statement on Form F-3 (No. 333-277578) of £1,250,000,000 8.500% fixed rate resetting perpetual subordinated contingent convertible securities (the “Securities”), to be issued under an indenture dated as of August 14, 2018 (as heretofore amended and supplemented, the “Base Indenture”), among the Company, The Bank of New York Mellon, London Branch, as trustee and paying agent (the “Trustee”), and The Bank of New York Mellon SA/NV, Luxembourg Branch, as registrar (the “Registrar”), as amended and supplemented by a tenth supplemental indenture (the “Tenth Supplemental Indenture”) and an eleventh supplemental indenture (the “Eleventh Supplemental Indenture”), each dated as of May 15, 2024 (the Tenth Supplemental Indenture and the Eleventh Supplemental Indenture together, the “Supplemental Indentures” and, together with the Base Indenture, the “Indenture”), among the Company, the Trustee and the Registrar. Such registration statement, as amended as of its most recent effective date (May 8, 2024), insofar as it relates to the Securities (as determined for purposes of Rule 430B(f)(2) under the Securities Act of 1933, as amended (the “Securities Act”)), including the documents incorporated by reference therein but excluding Exhibits 25.1, 25.2 and 25.3, is herein called the “Registration Statement.”

In arriving at the opinion expressed below, we have reviewed the following documents:

Barclays PLC, Page 2

In addition, we have made such investigations of law as we have deemed appropriate as a basis for the opinion expressed below.

In rendering the opinion expressed below, we have assumed the authenticity of all documents submitted to us as originals and the conformity to the originals of all documents submitted to us as copies. In addition, we have assumed and have not verified the accuracy as to factual matters of each document we have reviewed.

Based on the foregoing, and subject to the further assumptions and qualifications set forth below, it is our opinion that the Securities are valid, binding and enforceable obligations of the Company, entitled to the benefits of the Indenture; provided that we express no opinion as to the validity, binding effect or enforceability of Sections 5.04(d) and 12.01 of the Base Indenture, as amended by the Tenth Supplemental Indenture, and the corresponding provisions in the Global Security, which provisions are governed by English law.

Insofar as the foregoing opinion relates to the validity, binding effect or enforceability of any agreement or obligation of the Company, (a) we have assumed that the Company and each other party to such agreement or obligation has satisfied those legal requirements that are applicable to it to the extent necessary to make such agreement or obligation enforceable against it (except that no such assumption is made as to the Company regarding matters of the federal law of the United States of America or the law of the State of New York that in our experience normally would be applicable to general business entities with respect to such agreement or obligation), (b) such opinion is subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally and to general principles of equity, (c) we express no opinion with respect to the effect of any mandatory choice of law rules and (d) such opinion is subject to the effect of judicial application of foreign laws or foreign governmental actions affecting creditors’ rights.

We express no opinion as to the subject matter jurisdiction of any United States federal court to adjudicate any action relating to the Securities where jurisdiction based on diversity of citizenship under 28 U.S.C. §1332 does not exist.

We note that by statute New York provides that a judgment or decree rendered in a currency other than the currency of the United States shall be converted into U.S. dollars at the rate of exchange prevailing on the date of entry of the judgment or decree. There is no corresponding Federal statute and no controlling Federal court decision on this issue. Accordingly, we express no opinion as to whether a Federal court would award a judgment in a currency other than U.S. dollars or, if it did so, whether it would order conversion of the judgment into U.S. dollars.

The foregoing opinion is limited to the federal law of the United States of America and the law of the State of New York. With respect to matters governed by English law, we have relied on the opinion of Clifford Chance LLP dated May 15, 2024, as English counsel to the Company, which has been filed as Exhibit 5.2 to the Company’s Form 6-K dated May 15, 2024.

We hereby consent to the incorporation by reference of this opinion in the Registration Statement and the use of our name in the prospectus constituting a part of the Registration Statement and the prospectus supplement dated May 8, 2024, relating to the Securities under the heading “Validity of Securities.” In giving such consent, we do not

Barclays PLC, Page 3

thereby admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Securities and Exchange Commission thereunder.

The opinion expressed herein is rendered on and as of the date hereof, and we assume no obligation to advise you or any other person, or to make any investigations, as to any legal developments or factual matters arising subsequent to the date hereof that might affect the opinion expressed herein.

£1,250,000,000 8.500 per cent. Fixed Rate Resetting Perpetual Subordinated Contingent Convertible Securities (the “Securities”)

We have acted as English legal advisers to Barclays PLC (the “Issuer”) in connection with the issue by the Issuer of the Securities under the Contingent Capital Securities Indenture dated as of 14 August 2018, among the Issuer, The Bank of New York Mellon, London Branch as trustee (the “Trustee”) and The Bank of New York Mellon SA/NV, Luxembourg Branch, as Contingent Capital Security Registrar (the “Registrar”) (as amended by the Fourth Supplemental Indenture dated 12 August 2020, the Fifth Supplemental Indenture dated 1 March 2021, the Eighth Supplemental Indenture dated 6 March 2023, the Ninth Supplemental Indenture dated 22 November 2023 and the Tenth Supplemental Indenture dated 15 May 2024, together, the “Base Indenture”), as supplemented by the Eleventh Supplemental Indenture dated as of 15 May 2024, among the Issuer, the Trustee and the Registrar (the “Supplemental Indenture” and, together with the Base Indenture, the “Indenture”).

This Opinion relates to the Indenture and the Securities.

CLIFFORD CHANCE LLP IS A LIMITED LIABILITY PARTNERSHIP REGISTERED IN ENGLAND AND WALES UNDER NO. OC323571. THE FIRM’S REGISTERED OFFICE AND PRINCIPAL PLACE OF BUSINESS IS AT 10 UPPER BANK STREET LONDON E14 5JJ. THE FIRM USES THE WORD “PARTNER” TO REFER TO A MEMBER OF CLIFFORD CHANCE LLP OR AN EMPLOYEE OR CONSULTANT WITH EQUIVALENT STANDING AND QUALIFICATIONS. THE FIRM IS AUTHORISED AND REGULATED BY THE SOLICITORS REGULATION AUTHORITY

CLIFFORD CHANCE LLP

In connection with the creation and issue of the Securities and the giving of this Opinion:

This Opinion is governed by English law, relates only to English law as applied by the English courts as at today’s date and does not extend to the laws of any other jurisdiction (save as described in paragraph 1.5 (Taxation)). All non-contractual obligations and any other matters arising out of or in connection with this Opinion are governed by English law.

We express no opinion on any taxation matter, and none is implied or may be inferred, save as expressly specified in paragraph 2.6 (Taxation statements in the Prospectus Supplement). In respect of those tax matters this Opinion is confined to, and given on the basis of, English law, United Kingdom tax law and His Majesty’s Revenue and

- 2 -

CLIFFORD CHANCE LLP

Customs (“HMRC”) published practice in force or applied in the United Kingdom as at today’s date.

This Opinion is given on the basis of our understanding of the terms of the Indenture and the Securities, and the assumptions set out in Schedule 2 (Assumptions) and is subject to the reservations set out in Schedule 3 (Reservations). This Opinion is strictly limited to the matters stated in paragraph 2 (Opinion) and does not extend to any other matters.

We are of the opinion that:

The Issuer is a company duly incorporated in England and has the capacity and power to create and issue the Securities, to enter into the Base Indenture and the Supplemental Indenture and to exercise its rights and perform its obligations under the Securities and the Indenture.

The execution and delivery of the Base Indenture and the Supplemental Indenture and the issue of the Securities (and the allotment of the Conversion Shares) have been duly authorised by or on behalf of the Issuer.

The Issuer has duly executed and delivered the Base Indenture, the Supplemental Indenture and the Global Security, to the extent that English law is applicable.

In any proceedings taken in England for the enforcement of the Base Indenture or the Supplemental Indenture, the obligations expressed to be assumed by the Issuer in the Base Indenture and the Supplemental Indenture would be recognised by the English courts as legal, valid and binding obligations of the Issuer and would be enforceable in the English courts.

- 3 -

CLIFFORD CHANCE LLP

Section 12.01 (Subordination of Contingent Capital Securities – Status of the Contingent Capital Securities) of the Base Indenture constitutes legal, valid, binding and enforceable obligations of the Issuer.

The statements in the Prospectus Supplement under the heading “Tax Considerations—United Kingdom Taxation” are correct in all material respects.

ASSUMPTIONS

Where, for the purposes of paragraphs 1(a) and 1(b) of this Schedule 2:

- 8 -

CLIFFORD CHANCE LLP

- 9 -

CLIFFORD CHANCE LLP

Each party to the Indenture (other than the Issuer) has the capacity, power and authority to enter into and to exercise its rights and to perform its obligations under the Indenture.

CLIFFORD CHANCE LLP

Save for those listed in Schedule 1 (Documents and Enquiries) there is no other agreement, instrument, other arrangement or relationship between any of the parties to the Indenture which modifies, supersedes or conflicts with the Indenture.

There has been no alteration in the status or condition of the Issuer as disclosed by the searches and enquiries referred to in Schedule 1 (Documents and Enquiries). However,

- 11 -

CLIFFORD CHANCE LLP

it is our experience that the searches and enquiries referred to in paragraphs 2(a) and 2(b) in Schedule 1 (Documents and Enquiries) may be unreliable. In particular, they are not conclusively capable of disclosing whether or not insolvency proceedings have been commenced in England, nor do they indicate whether or not insolvency proceedings have begun elsewhere.

SCHEDULE 3

RESERVATIONS

In this Opinion “enforceable” means that an obligation is of a type which the English courts may enforce. It does not mean that those obligations will be enforced in all circumstances in accordance with the terms of the Securities and the Indenture. In particular:

- 13 -

CLIFFORD CHANCE LLP

If any proceedings are brought in the English courts by the Issuer, in some circumstances, those courts may accept jurisdiction, notwithstanding the provisions of the Indenture and the Securities providing that any state or federal court in the City and State of New York or in the Borough of Manhattan, the City of New York, as applicable, has jurisdiction in relation thereto.

- 14 -

CLIFFORD CHANCE LLP

If any obligation arising under the Indenture or the Securities is or is to be performed in a jurisdiction outside England, it may not be enforceable in the English courts to the

- 15 -

CLIFFORD CHANCE LLP

extent that performance would be illegal or contrary to public policy under the laws of the other jurisdiction. Further an English court may give effect to any overriding mandatory provisions of the law of the place of performance insofar as they render the performance unlawful or otherwise take into account the law of the place of performance in relation to the manner of performance and the steps to be taken in the event of defective performance.

The opinions set out in this letter are subject to any limitations arising from any measures taken pursuant to the stabilisation powers under the special resolution regime under the Banking Act 2009, as amended.
