if any additional Fixed-to-Floating Rate Notes of any series are issued after the Issue Date, except, in the case of such series, for the period of six months beginning on the issue date for any such additional Fixed-to-Floating Rate Notes of the applicable series) to (but excluding) the applicable Fixed-to-Floating Rate Notes Par Redemption Date, at an amount equal to the higher of (i) 100% of the principal amount of the Fixed-to-Floating Rate Notes to be redeemed and (ii) as determined by the Determination Agent, the sum of the present values of the principal (discounted from the applicable Fixed-to-Floating Rate Notes Par Redemption Date) and remaining payments of interest to be made on any scheduled Fixed Rate Period Interest Payment Date to the applicable Fixed-to-Floating Rate Notes Par Redemption Date for the Fixed-to-Floating Rate Notes of such series to be redeemed (not including accrued but unpaid interest, if any, on the principal amount of the Fixed-to-Floating Rate Notes of such series) discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Optional Redemption Treasury Rate plus (x) 30 basis points in the case of 2027 Notes, (y) 35 basis points in the case of 2029 Notes and (z) 40 basis points in the case of 2034 Notes, together with, in either case of (i) or (ii) above, accrued but unpaid interest, if any, on the principal amount of the Fixed-to-Floating Rate Notes to be redeemed to (but excluding) the Redemption Date (the “Make-Whole Redemption”); and/or (B) any series of the Securities then outstanding, in whole but not in part of such series, on the applicable Par Redemption Date, at an amount equal to 100% of their principal amount together with accrued but unpaid interest, if any, on the principal amount of the Securities to be redeemed to (but excluding) the Redemption Date (the “Par Redemption”).

“Optional Redemption Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to: (1) the yield, under the heading which represents the average for the week immediately prior to the calculation date, appearing in the most recently published statistical release designated “H.15,” or any successor publication that is published by the Board of Governors of the Federal Reserve System that establishes yields on actively traded U.S. Treasury securities adjusted to constant maturity, under the caption “Treasury constant maturities,” for the maturity most closely corresponding to the applicable Fixed-to-Floating Rate Notes Par Redemption Date of the Fixed-to-Floating Rate Notes to be redeemed (if no maturity is within three months before or after the applicable Fixed-to-Floating Rate Notes Par Redemption Date of the Fixed-to-Floating Rate Notes to be redeemed, yields for the two published maturities most closely corresponding to the Optional Redemption Comparable Treasury Issue shall be determined and the Optional Redemption Treasury Rate shall be interpolated or extrapolated from such yields on a straight-line basis, rounding to the nearest month); or (2) if such release (or any successor release) is not published during the week immediately prior to the calculation date or does not contain such yields, the rate per annum equal to the semi-annual equivalent yield to maturity of the Optional Redemption Comparable Treasury Issue, calculated using a price for the Optional Redemption Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Optional Redemption Comparable Treasury Price for such Redemption Date; provided that, if the period from the Redemption Date to the applicable Fixed-to-Floating Rate Notes Par Redemption Date is less than one year, the weekly average yield on actually traded U.S. Treasury securities adjusted to a constant maturity of one year will be used.

The Optional Redemption Treasury Rate shall be calculated by the Determination Agent on the third Business Day preceding such Redemption Date.

In determining the Optional Redemption Treasury Rate, the below terms will have the following meaning:

12

“Optional Redemption Comparable Treasury Issue” means, with respect to any Redemption Date, the U.S. Treasury security selected by the Determination Agent as having an actual or interpolated maturity comparable with the remaining term to the applicable Fixed-to-Floating Rate Notes Par Redemption Date of the relevant Fixed-to-Floating Rate Notes that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities denominated in U.S. dollars and of comparable maturity to the remaining term to the applicable Fixed-to-Floating Rate Notes Par Redemption Date of the relevant Fixed-to-Floating Rate Notes.

“Optional Redemption Comparable Treasury Price” means, with respect to any Redemption Date, (i) the arithmetic average of the Optional Redemption Reference Treasury Dealer Quotations for such Redemption Date (calculated on the third Business Day preceding such Redemption Date), after excluding the highest and lowest such Optional Redemption Reference Treasury Dealer Quotations, or (ii) if fewer than five such Optional Redemption Reference Treasury Dealer Quotations are received, the arithmetic average of all such quotations, or (iii) if fewer than two such Optional Redemption Reference Treasury Dealer Quotations are received, then such Optional Redemption Reference Treasury Dealer Quotation.

“Determination Agent” means an investment bank or financial institution of international standing selected by the Company and which may be an affiliate of the Company.

“Optional Redemption Reference Treasury Dealer” means, with respect to the Redemption Date, each of up to five banks selected by the Company (following, where practicable, consultation with the Determination Agent, if applicable), or the affiliates of such banks, which are (i) primary U.S. government securities dealers, and their respective successors, or (ii) market makers in pricing corporate bond issues.

“Optional Redemption Reference Treasury Dealer Quotations” means, with respect to each Optional Redemption Reference Treasury Dealer and any Redemption Date, the arithmetic average, as determined by the Determination Agent, of the bid and offered prices (as quoted to the Determination Agent by such Optional Redemption Reference Treasury Dealer) for the applicable Optional Redemption Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) at 11:00 a.m., New York time, on the third Business Day preceding such Redemption Date.

Unless the Company defaults on payment of the Redemption Price, interest will cease to accrue on the Redemption Date on the Securities or portions thereof called for redemption. The Trustee has no responsibility for any calculation or determination in respect of the establishment of the Make-Whole Redemption price and shall be entitled to receive and rely conclusively upon an Officer’s Certificate executed in accordance with the Base Indenture that states the Make-Whole Redemption price.

SECTION 2.05 Loss Absorption Disqualification Event Redemption. If a Loss Absorption Regulations Event occurs on or after the Issue Date that does, or would be likely to (in the opinion of the Company, the PRA or the Relevant U.K. Resolution Authority), result in a Loss Absorption Disqualification Event with respect to any series of the Securities, the Company may, at the Company’s option, at any time, redeem the Securities of such series, in whole of such series but not in part of such series, at a Redemption Price equal to 100% of the principal amount of the Securities being redeemed together with accrued but unpaid interest, if any, on the principal amount of the Securities to be redeemed to (but excluding) the relevant Redemption Date. For the avoidance of doubt, except as otherwise set forth in this Fifteenth Supplemental Indenture, Article 11 of the Base Indenture shall apply to any redemption of Securities pursuant to this Section 2.05 in respect of each series of the Securities, separately.

13

SECTION 2.06 Notice of Redemption.

(a) Before the Company may redeem the Securities of any series pursuant to Section 2.04 or Section 2.05 hereof or pursuant to Section 11.09 of the Base Indenture, the Company shall deliver via DTC or the relevant clearing system(s) (or, if the Securities of such series are definitive Securities, to the Holders at their addresses shown on the register for such Securities) prior notice of not less than fifteen (15) days, nor more than sixty (60) days, to the Holders of such Securities.

Such notice shall specify the Company’s election to redeem the Securities of such series and the date fixed for such redemption and shall be irrevocable except in the limited circumstances described in paragraphs (b) below.

(b) If the Company has delivered a notice of redemption pursuant to paragraph (a) of this Section 2.06, but prior to the payment of the redemption amount with respect to such redemption the Relevant U.K. Resolution Authority exercises its U.K. Bail-in Power with respect to the Securities of the series to be redeemed, such redemption notice shall be automatically rescinded and shall be of no force and effect, and no payment in respect of the redemption amount shall be due and payable.

(c) If any event specified in paragraph (b) above occurs, the Company shall promptly deliver notice to the Holders of such Securities via DTC or the relevant clearing system(s) (or, if the Securities of such series are definitive Securities, to the Holders at their addresses shown on the shown on the register for the Securities of such series) and to the Trustee directly, specifying the occurrence of the relevant event.

From (and including) the Par Redemption Date to (but excluding) the Maturity Date (the “Floating Rate Period”), interest will accrue on the Securities at a floating rate equal to the Benchmark (as defined below and such term being subject to the provisions of Annex I to the Fifteenth Supplemental Indenture) as determined on the applicable Interest Determination Date, plus 1.88% per annum (the “Margin”). During the Floating Rate Period, interest will be payable quarterly in arrear on December 13, 2026, March 13, 2027, June 13, 2027, and the Maturity Date (each a “Floating Rate Period Interest Payment Date” and together with the Fixed Rate Period Interest Payment Dates, each an “Interest Payment Date”).

In accordance with and subject to the Benchmark Transition Provisions, after a Benchmark Transition Event and related Benchmark Replacement Date have occurred, the amount of interest that will be payable on the Securities during each Floating Rate Interest Period will be determined by reference to a rate per annum equal to the Benchmark Replacement plus the Margin, provided that, if the Company or its designee (in consultation with the Company) are unable to or do not timely determine a Benchmark Replacement in accordance with the Benchmark Transition Provisions or if there is a Derecognition Risk, the interest rate for the related Floating Rate Interest Period will be equal to the interest rate in effect for the immediately preceding Floating Rate Interest Period, or in the case of the Interest Determination Date prior to the first Floating Rate Period Interest Payment Date, the Fixed Interest Rate.

Subject to the limitations specified on the reverse of this Security, interest on the Securities shall be computed and payable in arrear on the basis of a 360-day year of twelve 30-day months during the Fixed Rate Period and on the basis of the actual number of days in each Floating Rate Interest Period and a 360-day year during the Floating Rate Period.

The Calculation Agent, initially The Bank of New York Mellon, New York (the “Calculation Agent”), will determine the Benchmark in any circumstance where the Calculation Agent is so required under the terms of the Securities and the Indenture, in accordance with the provisions set forth in Annex I to the Fifteenth Supplemental Indenture.

All calculations made by the Calculation Agent for the purposes of calculating the interest rate on the Securities shall be conclusive and binding on the Holders of the Securities, the Company and the Trustee, absent manifest error. None of the Company, the Calculation Agent, the Trustee or any paying agent shall be responsible for determining whether manifest error has occurred or any liability therefor.

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.

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 DTC as soon as practicable regarding such exercise of the U.K. Bail-in Power for purposes of notifying holders of such occurrence. The Company shall also deliver a copy of such notice to the Trustee for information purposes.

From (and including) the Par Redemption Date to (but excluding) the Maturity Date (the “Floating Rate Period”), interest will accrue on the Securities at a floating rate equal to the Benchmark (as defined below and such term being subject to the provisions of Annex I to the Fifteenth Supplemental Indenture) as determined on the applicable Interest Determination Date, plus 2.22% per annum (the “Margin”). During the Floating Rate Period, interest will be payable quarterly in arrear on December 13, 2028, March 13, 2029, June 13, 2029, and the Maturity Date (each a “Floating Rate Period Interest Payment Date” and together with the Fixed Rate Period Interest Payment Dates, each an “Interest Payment Date”).

(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 Senior Debt Securities Indenture, dated as of January 17, 2018 (as heretofore amended and supplemented, the “Base Indenture”), between the Company and The Bank of New York Mellon, London Branch, as Trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture (as defined below)) as amended and supplemented by the Fifteenth Supplemental Indenture, dated as of September 13, 2023 (the “Fifteenth 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 Indenture 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 $300,000,000, 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.

The provisions set forth in Section 10.04 of the Base Indenture are applicable to this Security. In addition, 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.

The Company may redeem the Securities pursuant to Section 2.04 of the Fifteenth Supplemental Indenture. The Company may also redeem the Securities pursuant to Section 11.09 of the Base Indenture and/or Section 2.05 of the Fifteenth Supplemental Indenture. Any redemption of Securities by the Company is subject to the notice period and provisions set forth in Sections 11.02 and 11.04 of the Base Indenture and in Section 2.06 of the Fifteenth Supplemental Indenture, and to the conditions set forth in Section 11.10 of the Base Indenture.

The Company may repurchase the Securities pursuant to Section 11.12 of the Base Indenture.

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

The Securities shall constitute the Company’s direct, unconditional, unsecured and unsubordinated obligations and shall rank as set forth in Section 2.01(k) of the Fifteenth Supplemental Indenture.

D-8

The Securities are subject to the waiver of set-off provisions set forth in Section 5.01(h) of the Base Indenture.

This Security is subject to the provisions regarding the U.K. Bail-in Power Acknowledgement set forth in Section 12.01 of the Base Indenture.

The Securities are subject to provisions set forth in Article 5 of the Base Indenture.

If a Winding-Up Event occurs, the outstanding principal amount of this Security, together with any accrued but unpaid interest thereon, 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.

If a Non-Payment Event occurs, 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.

Subject to applicable law, no Holder of Securities may exercise, claim or plead any right of set-off, compensation, 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, be deemed to have waived all such rights of set-off, compensation, 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, 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, retention and netting.

The Indenture permits the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities to be affected under the Indenture as contemplated by Article 9 of the Base Indenture. To the extent required by the U.S. Trust Indenture Act of 1939, as amended, but otherwise notwithstanding any other provision in this Security, the Holder of this Security shall have the right to receive (subject to Section 3.07 of the Base Indenture) payment of any principal of, and interest on, this Security when due (or, in the case of redemption, on or after the Redemption Date), and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder or holder.

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 provisions on registration, transfer and exchange of the Securities set forth in Section 3.05 of the Base Indenture are applicable to the Securities.

D-9

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 waiver of set-off provisions referenced herein and set forth in Section 5.01(h) of the Base Indenture, which shall be governed by and construed in accordance with English law.
