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 for each interest period on the Notes during the Floating Rate Period will be determined by reference to a rate per annum equal to the Benchmark Replacement plus the Margin.

SECTION 3.03. *Benchmark Transition Provisions.*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) If the Company (in consultation, to the extent practicable, with the Calculation Agent) or the Company's designee (in consultation with the Company) determines that a Benchmark Transition Event and related Benchmark Replacement Date have occurred prior to the applicable Reference Time in respect of any determination of the Benchmark on any date, the applicable Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the Notes during the Floating Rate Period in respect of such determination on such date and all determinations on all subsequent dates; <u>provided</u> that, if the Company (in consultation, to the extent practicable, with the Calculation Agent) or the Company's designee (in consultation with the Company) is unable to or does not determine a Benchmark Replacement in accordance with the provisions below prior to 5:00 p.m. (New York time) on the relevant Interest Determination Date, 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 Initial Interest Rate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) In connection with the implementation of a Benchmark Replacement, the Company (in consultation, to the extent practicable, with the Calculation Agent) or the Company's designee (in consultation with the Company) will have the right to make changes to (i) any Interest Determination Date, Floating Rate Period Interest Payment Date, Reference Time, business day convention or Floating Rate Interest Period, (ii) the manner, timing and frequency of determining the rate and amounts of interest that are payable on the Notes during the Floating Rate Period and the conventions relating to such determination and calculations with respect to interest, (iii) rounding conventions, (iv) tenors and (v) any other terms or provisions of the Notes during the Floating Rate Period, in each case that the Company (in consultation, to the extent practicable, with the Calculation Agent) or the Company's designee (in consultation with the Company) determines, from time to time, to be appropriate to reflect the determination and implementation of such Benchmark Replacement in a manner substantially consistent with market practice (or, if the Company (in consultation, to the extent practicable, with the Calculation Agent) or the Company's designee (in consultation with the Company) decides that implementation of any portion of such market practice is not administratively feasible or determine that no market practice for use of the Benchmark Replacement exists, in such other manner as the Company (in consultation, to the extent practicable, with the Calculation Agent) or the Company's designee (in consultation with the Company) determines is appropriate (acting in good faith)) (the "<u>Benchmark Replacement Conforming Changes</u>"). Any Benchmark Replacement Conforming Changes will apply to the Notes for all future Floating Rate Interest Periods.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) All percentages resulting from any calculation in connection with any interest rate on the Notes shall be rounded, if necessary, to the nearest one hundred thousandth of a percentage point, with five one-millionths of a percentage point rounded upward (for example, 9.876545% (or 0.09876545) would be rounded to 9.87655% (or 0.0987655)), and all Applicable Currency amounts would be rounded to the nearest cent, with one-half cent being rounded upward.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) All determinations, decisions, elections and any calculations made by the Company, the Calculation Agent or the Company's designee for the purposes of calculating the applicable interest on the Notes will be conclusive and binding on the Holders, the Company, the Trustee and the Paying Agent, absent manifest error. If made by the Company, such determinations, decisions, elections and calculations will be made in consultation with the Calculation Agent, to the extent practicable. If made by the Company's designee, such determinations, decisions, elections and calculations will be made after consulting with the Company, and the Company's designee will not make any such determination, decision, election or calculation to which the Company objects. Notwithstanding anything to the contrary in the Indenture or the Notes, any determinations, decisions, calculations or elections made in accordance with this provision will become effective without consent from the Holders or any other party.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) Any determination, decision or election relating to the Benchmark not made by the Calculation Agent will be made on the basis described above. The Calculation Agent shall have no liability for not making any such determination, decision or election. In addition, the Company may designate an entity (which may be the Company's Affiliate) to make any determination, decision or election that the Company has the right to make in connection with the determination of the Benchmark.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) Notwithstanding any other provision of "Benchmark Transition Provisions" set forth above, no Benchmark Replacement will be adopted, nor will the applicable Benchmark Replacement Adjustment be applied, nor will any Benchmark Replacement Conforming Changes be made, if, in the Company's determination, the same could reasonably be expected to prejudice the qualification of the Notes as own funds instruments of the HSBC Group for the purposes of the Applicable Rules.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) By its acquisition of the Notes, each Holder (which, for these purposes, includes each beneficial owner) (i) acknowledges, accepts, consents and agrees to be bound by the Company's or its designee's determination of a Benchmark Transition Event, a Benchmark Replacement Date, the Benchmark Replacement, the Benchmark Replacement Adjustment and any Benchmark Replacement Conforming Changes, including as may occur without any prior notice from the Company and without the need for the Company to obtain any further consent from such Holder, (ii) waives any and all claims, in law and/or in equity, against the Trustee, the Paying Agent and the Calculation Agent or the Company's designee for, agrees not to initiate a suit against the Trustee, the Paying Agent and the Calculation Agent or the Company's designee in respect of, and agrees that none of the Trustee, the Paying Agent or the Calculation Agent or the Company's designee will be liable for, the determination of or the failure to determine any Benchmark Transition Event, any Benchmark Replacement Date, any Benchmark Replacement, any Benchmark Replacement Adjustment and any Benchmark Replacement Conforming Changes, and any losses suffered in connection therewith and (iii) agrees that none of the Trustee, the Paying Agent or the Calculation Agent or the Company's designee will have any obligation to determine any Benchmark Transition Event, any Benchmark Replacement Date, any Benchmark Replacement, any Benchmark Replacement Adjustment and any Benchmark Replacement Conforming Changes (including any adjustments thereto), including in the event of any failure by the Company to determine any Benchmark Transition Event, any Benchmark Replacement Date, any Benchmark Replacement, any Benchmark Replacement Adjustment and any Benchmark Replacement Conforming Changes.

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 for each interest period on the Debt Securities during the Floating Rate Period will be determined by reference to a rate per annum equal to the Benchmark Replacement plus the Margin.

"<u>designee</u>" means an Affiliate or any other agent of the Issuer.

"<u>Reference Time</u>" means (i) if the Benchmark is Compounded Daily SOFR, for each USGS Business Day, 3:00 p.m. (New York time) on the next succeeding USGS Business Day, and (ii) if the Benchmark is not Compounded Daily SOFR, the time determined by the Issuer (in consultation, to the extent practicable, with the Calculation Agent) or the Issuer's designee (in consultation with the Issuer) in accordance with the Benchmark Replacement Conforming Changes.

*Benchmark Transition Provisions.* If the Issuer (in consultation, to the extent practicable, with the Calculation Agent) or the Issuer's designee (in consultation with the Issuer) determines that a Benchmark Transition Event and related Benchmark Replacement Date have occurred prior to the applicable Reference Time in respect of any determination of the Benchmark on any date, the applicable Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the Debt Securities during the Floating Rate Period in respect of such determination on such date and all determinations on all subsequent dates; *provided* that, if the Issuer (in consultation, to the extent practicable, with the Calculation Agent) or the Issuer's designee (in consultation with the Issuer) is unable to or does not determine a Benchmark Replacement in accordance with the provisions below prior to 5:00 p.m. (New York time) on the relevant Interest Determination Date, 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 Initial Interest Rate.

In connection with the implementation of a Benchmark Replacement, the Issuer (in consultation, to the extent practicable, with the Calculation Agent) or the Issuer's designee (in consultation with the Issuer) will have the right to make changes to (i) any Interest Determination Date, Floating Rate Period Interest Payment Date, Reference Time, business day convention or Floating Rate Interest Period, (ii) the manner, timing and frequency of determining the rate and amounts of interest that are payable on the Debt Securities during the Floating Rate Period and the conventions relating to such determination and calculations with respect to interest, (iii) rounding conventions, (iv) tenors and (v) any other terms or provisions of the Debt Securities during the Floating Rate Period, in each case that the Issuer (in consultation, to the extent practicable, with the Calculation Agent) or the Issuer's designee (in consultation with the Issuer) determine, from time to time, to be appropriate to reflect the determination and implementation of such Benchmark Replacement in a manner substantially consistent with market practice (or, if the Issuer (in consultation, to the extent practicable, with the Calculation Agent) or the Issuer's designee (in consultation with the Issuer) decide that implementation of any portion of such market practice is not administratively feasible or determine that no market practice for use of the Benchmark Replacement exists, in such other manner as the Issuer (in consultation, to the extent practicable, with the Calculation Agent) or the Issuer's designee (in consultation with the Issuer) determine is appropriate (acting in good faith)) (the "<u>Benchmark Replacement Conforming Changes</u>"). Any Benchmark Replacement Conforming Changes will apply to the Debt Securities for all future Floating Rate Interest Periods.

------

The Issuer will promptly give notice of the determination of the Benchmark Replacement, the Benchmark Replacement Adjustment and any Benchmark Replacement Conforming Changes to the Trustee, the Paying Agent, the Calculation Agent and the Holders; <u>provided</u> that failure to provide such notice will have no impact on the effectiveness of, or otherwise invalidate, any such determination.

All percentages resulting from any calculation in connection with any interest rate in respect of this Global Security shall be rounded, if necessary, to the nearest one hundred thousandth of a percentage point, with five one-millionths of a percentage point rounded upward (for example, 9.876545% (or 0.09876545) would be rounded to 9.87655% (or 0.0987655)), and all Applicable Currency amounts would be rounded to the nearest cent, with one-half cent being rounded upward.

All determinations, decisions, elections and any calculations made by the Issuer, the Calculation Agent or the Issuer's designee for the purposes of calculating the applicable interest on the Debt Securities will be conclusive and binding on the Holders, the Issuer, the Trustee and the Paying Agent, absent manifest error. If made by the Issuer, such determinations, decisions, elections and calculations will be made in consultation with the Calculation Agent, to the extent practicable. If made by the Issuer's designee, such determinations, decisions, elections and calculations will be made after consulting with the Issuer, and the Issuer's designee will not make any such determination, decision, election or calculation to which the Issuer objects. Notwithstanding anything to the contrary in the Indenture or the Debt Securities, any determinations, decisions, calculations or elections made in accordance with this provision will become effective without consent from the Holders or any other party.

Any determination, decision or election relating to the Benchmark not made by the Calculation Agent will be made on the basis described above. The Calculation Agent shall have no liability for not making any such determination, decision or election. In addition, the Issuer may designate an entity (which may be the Issuer's Affiliate) to make any determination, decision or election that the Issuer has the right to make in connection with the determination of the Benchmark.

Notwithstanding any other provision of "Benchmark Transition Provisions" set forth above, no Benchmark Replacement will be adopted, nor will the applicable Benchmark Replacement Adjustment be applied, nor will any Benchmark Replacement Conforming Changes be made, if in the Issuer's determination, the same could reasonably be expected to prejudice the qualification of the Debt Securities as own funds instruments of the HSBC Group for the purposes of the Applicable Rules.

By its acquisition of the Debt Securities, each Holder (which, for these purposes, includes each beneficial owner) (i) acknowledges, accepts, consents and agrees to be bound by the Issuer's or its designee's determination of a Benchmark Transition Event, a Benchmark Replacement Date, the Benchmark Replacement, the Benchmark Replacement Adjustment and any Benchmark Replacement Conforming Changes, including as may occur without any prior notice from the Issuer and without the need for the Issuer to obtain any further consent from such Holder, (ii) waives any and all claims, in law and/or in equity, against the Trustee, the Paying Agent and the Calculation Agent or the Issuer's designee for, agrees not to initiate a suit against the Trustee, the Paying Agent and the Calculation Agent or the Issuer's designee in respect of, and agrees that none of the Trustee, the Paying Agent or the Calculation Agent or the Issuer's designee will be liable for, the determination of or the failure to determine any Benchmark Transition Event, any Benchmark Replacement Date, any Benchmark Replacement, any Benchmark Replacement Adjustment and any Benchmark Replacement Conforming Changes, and any losses suffered in connection therewith and (iii) agrees that none of the Trustee, the Paying Agent or the Calculation Agent or the Issuer's designee will have any obligation to determine any Benchmark Transition Event, any Benchmark Replacement Date, any Benchmark Replacement, any Benchmark Replacement Adjustment and any Benchmark Replacement Conforming Changes (including any adjustments thereto), including in the event of any failure by the Issuer to determine any Benchmark Transition Event, any Benchmark Replacement Date, any Benchmark Replacement, any Benchmark Replacement Adjustment and any Benchmark Replacement Conforming Changes.

Any interest in respect of this Global Security that is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called "<u>Defaulted Interest</u>") shall forthwith cease to be payable to the Holders thereof on the relevant Regular Record Date by virtue of their having been such Holders; and such Defaulted Interest may be paid by the Issuer, at its election in each case, as provided in Clause (1) or (2) below:

Whenever in this Global Security there is mentioned, in any context, the payment of interest, if any, on, or in respect of, any Debt Security or the net proceeds received on the sale or exchange of any Debt Security, such mention shall be deemed to include mention of the payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof and express mention of the payment of Additional Amounts (if applicable) in any provision hereof shall not be construed as excluding Additional Amounts in those provisions hereof where such express mention is not made.

Upon any exchange of a portion of this Global Security for a definitive Debt Security, the portion of the principal amount hereof so exchanged shall be endorsed by the Registrar on Schedule A hereto. The principal amount hereof shall be reduced for all purposes by the amount so exchanged and endorsed.

------

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

The rights of Holders shall, in the event of the winding up of the Issuer, to the extent more fully set out in the Indenture, be subordinated and subject in right of payment to the prior payment in full of all claims of creditors of the Issuer except creditors in respect of any liability of the Issuer however arising for the payment of money, the right to payment of which by the Issuer by the terms thereof is, or is expressed to be, subordinated in the event of a winding up of the Issuer to the claims of all or any of the creditors of the Issuer, and creditors in respect of debt securities with no maturity issued pursuant to a separate indenture of even date as the Base Indenture between the Issuer and a trustee.

Subject to the limitations specified below and in Section 11.01 of the Base Indenture, as amended by Section 4.01 of the Tenth Supplemental Indenture, and Section 11.04 of the Base Indenture, the Debt Securities may be redeemed, in whole but not in part, at the Issuer's sole discretion, on not less than 10 nor more than 60 days' notice, at any time at a Redemption Price equal to 100% of the principal amount thereof (and premium, if any), together with accrued but unpaid interest, if any, in respect of such Debt Securities to (but excluding) the date fixed for redemption (a "Tax Event Redemption"), if, at any time, the Issuer shall determine that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) in making payment under such Debt Securities in respect of principal (or premium, if any), interest or missed payment the Issuer has or will or would become obligated to pay Additional Amounts, provided such obligation to pay Additional Amounts as provided in the Indenture and in this Global Security results from a change in or amendment to the laws of the Taxing Jurisdiction, or any change in the official application or interpretation of such laws (including a decision of any court or tribunal), or any change in, or in the official application or interpretation of, or execution of, or amendment to, any treaty or treaties affecting taxation to which the United Kingdom is a party, which change, amendment or execution becomes effective on or after the Issue Date; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) the payment of interest in respect of such Debt Securities has become or will or would be treated as a "distribution" within the meaning of Section 1000 of the Corporation Tax Act 2010 of the United Kingdom (or any statutory modification or reenactment thereof for the time being) as a result of any change in or amendment to the laws of the Taxing Jurisdiction, or any change in the official application or interpretation of such laws including a decision of any court, which change or amendment becomes effective on or after the Issue Date; *provided*, however, that in the case of (i) above, no notice of redemption shall be given earlier than 90 days prior to the earliest date on which the Issuer would be obliged to pay Additional Amounts were a payment in respect of such Debt Securities then due.

"<u>Capital Disqualification Event</u>" means an event that shall be deemed to have occurred if the Issuer determines, at any time after the Issue Date, there is a change in the regulatory classification of the Debt Securities that results or will result in either their:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) exclusion in whole or in part from the regulatory capital for the HSBC Group; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) reclassification in whole or in part as a form of regulatory capital of the HSBC Group that is lower than tier

Subject to the limitations specified below and in Section 11.01 of the Base Indenture, as amended by Section 4.01 of the Tenth Supplemental Indenture, and Section 11.04 of the Base Indenture, the Debt Securities may be redeemed, in whole but not in part, at the Issuer's option in its sole discretion, on not less than 10 nor more than 60 days' notice, on the Par Redemption Date. The Redemption Price will be equal to 100% of their principal amount plus any accrued and unpaid interest to (but excluding) the Par Redemption Date.

Subject to the limitations specified below and in Section 11.01 of the Base Indenture, as amended by Section 4.01 of the Tenth Supplemental Indenture, and Section 11.04 of the Base Indenture, if the aggregate principal amount of the Debt Securities then Outstanding is 25% or less of the aggregate principal amount of the Debt Securities originally issued (and, for these purposes, any additional securities issued after the Issue Date and consolidated with the Debt Securities as part of the same series shall be deemed to have been originally issued), the Issuer may, at its option in its sole discretion, on not less than 10 nor more than 60 days' notice, redeem the remaining Outstanding Debt Securities in whole (but not in part) at any time at a redemption price equal to 100% of the principal amount of such Outstanding Debt Securities plus any accrued and unpaid interest to (but excluding) the date fixed for redemption.

It shall be sufficient for the Issuer to deliver to the Trustee an Officer's Certificate stating that the Issuer is entitled to effect such redemption and setting forth a statement of facts showing that the aggregate principal amount of the Debt Securities then Outstanding is 25% or less of the aggregate principal amount of the Debt Securities originally issued. For these purposes, the Trustee and the Paying Agent shall accept such Officer's Certificate without further enquiry as sufficient evidence of the existence of such circumstances and such Officer's Certificate will be conclusive and binding on the Holders and Beneficial Owners.

At any time after such a declaration of acceleration with respect to the Debt Securities of this series has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee, the Holders of a majority in principal amount of the Outstanding Debt Securities of this series, by written notice to the Issuer and the Trustee, may rescind and annul such declaration and its consequences in certain circumstances, as provided in the Indenture. If a Default with respect to Debt Securities of this series occurs and is continuing, the Trustee may pursue certain remedies as set forth in the Indenture. The Holders of not less than a majority in aggregate principal amount of the Outstanding Debt Securities of this series may on behalf of all Holders waive any past Event of Default or any Default under the Indenture or the Debt Securities and its consequences except a default (i) in the payment of principal of or any installment of interest on the Debt Securities or (ii) in respect of a covenant or provision which under the Indenture cannot be modified or amended without the consent of the Holder of this Debt Security, and any such consent or waiver shall bind every future Holder of this Debt Security and of any Debt 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 Debt Security or such other Debt Securities.

An "<u>Event of Default</u>" with respect to the Debt Securities means any one of the following events: (i) an order is made by an English court which is not successfully appealed within 30 days after the date such order was made for winding up of the Issuer other than in connection with a scheme of amalgamation or reconstruction not involving bankruptcy or insolvency; or (ii) an effective resolution is validly adopted by the Issuer's shareholders for winding up of the Issuer other than in connection with a scheme of amalgamation or reconstruction not involving bankruptcy or insolvency.

A "<u>Default</u>" with respect to the Debt Securities means any one of the following events: (i) failure to pay principal or premium, if any, on the Debt Securities at maturity, and such default continues for a period of 30 days; or (ii) failure to pay any interest on the Debt Securities when due and payable, which failure continues for 30 days.

If a Default occurs, the Trustee may institute proceedings in England (but not elsewhere) for the Issuer's winding up; *provided* that the Trustee may not, upon the occurrence of a Default, accelerate the maturity of any Debt Securities then Outstanding, unless an Event of Default has occurred and is continuing.

The Indenture contains provisions permitting the Issuer and the Trustee (i) without the consent of the Holders of any Debt Securities issued under the Indenture to execute one or more supplemental indentures for certain enumerated purposes, such as to cure any ambiguity or to secure the Debt Securities, and (ii) with the consent of the Holders of not less than a majority in aggregate principal amount of the Outstanding Debt Securities of each series of Debt Securities affected thereby, to execute supplemental indentures for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of modifying in any manner the rights of Holders under the Indenture; <u>provided that</u>, with respect to certain enumerated provisions, no such supplemental indenture may be entered into without the consent of the Holder of each Outstanding Debt Security affected thereby. The Indenture also permits the Holders of at least a majority in aggregate principal amount of the Outstanding Debt Securities of each series to be affected, on behalf of the Holders of all Debt Securities of such series, to waive compliance by the Issuer with certain restrictive provisions of the Indenture. Any such consent or waiver by the Holder of this Global Security shall bind every future Holder of this Global Security and of any Global 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 Global Security or such other Global Securities.

------

Subject to the terms of the Indenture, the Depositary may surrender this Global Security or any portion hereof in exchange, in whole or in part, for definitive Debt Securities, of this series in registered form and the Registrar, acting on behalf of the Issuer, shall authenticate and deliver in exchange for this Global Security or the portions thereof to be exchanged, an equal aggregate face amount of definitive Debt Securities (duly countersigned) in the numbers and in the names advised by the Depositary.

No repayment or payment of Amounts Due shall become due and payable or be paid after the exercise of any UK Bail-in Power by the Relevant UK Resolution Authority if and to the extent such amounts have been reduced, converted, cancelled, amended or altered as a result of such exercise.

The exercise of the UK Bail-in Power by the Relevant UK Resolution Authority with respect to the Debt Securities shall not constitute an Event of Default or a Default.

"<u>Amounts Due</u>" means the principal amount of, and any accrued and unpaid interest, including any Additional Amounts, on, the Debt Securities. References to such amounts will include amounts that have become due and payable, but which have not been paid, prior to the exercise of any UK Bail-in Power by the Relevant UK Resolution Authority.

By its acquisition of the Debt Securities represented by this Global Security, each Holder (which, for these purposes, includes each beneficial owner of the Debt Securities): acknowledges, accepts, consents and agrees, notwithstanding any other term of the Debt Securities, the Indenture or any other agreements, arrangements or understandings between the Issuer and any Holder, to be bound by: (x) the effect of the exercise of any UK Bail-in Power by the Relevant UK Resolution Authority that (without limitation) may include and result in any of the following, or some combination thereof: (i) the reduction of all, or a portion, of the Amounts Due; (ii) the conversion of all, or a portion, of the Amounts Due into the Issuer's or another Person's ordinary shares, other securities or other obligations (and the issue to, or conferral on, the Holder of such ordinary shares, other securities or other obligations), including by means of an amendment, modification or variation of the terms of the Debt Securities or the Indenture; (iii) the cancellation of the Debt Securities; and/or (iv) the amendment or alteration of the Maturity Date or amendment of the amount of interest payable on the Debt Securities, or the Interest Payment Dates, including by suspending payment for a temporary period; and (y) the variation of the terms of the Debt Securities or the Indenture, if necessary, to give effect to the exercise of any UK Bail-in Power by the Relevant UK Resolution Authority.

------

By its acquisition of the Debt Securities, each Holder (which, for these purposes, includes each beneficial owner of the Debt Securities): (a) acknowledges and agrees that the exercise of the UK Bail-in Power by the Relevant UK Resolution Authority with respect to the Debt Securities shall not give rise to a Default or Event of Default for purposes of Section 315(b) (Notice of Default) and Section 315(c) (Duties of the Trustee in Case of Default) of the Trust Indenture Act; (b) to the extent permitted by the Trust Indenture Act, waives any and all claims, in law and/or in equity, against the Trustee for, agrees not to initiate a suit against the Trustee in respect of, and agrees that the Trustee shall not be liable for, any action that the Trustee takes, or abstains from taking, in either case in accordance with the exercise of (i) the UK Bail-in Power by the Relevant UK Resolution Authority with respect to the Debt Securities or (ii) the limited remedies available under the Indenture and the Debt Securities for a non-payment of principal and/or interest on the Debt Securities; and (c) acknowledges and agrees that, upon the exercise of any UK Bail-in Power by the Relevant UK Resolution Authority, the Trustee shall not be required to take any further directions from Holders under Section 5.12 (*Control by Holders of Debt Securities*) of the Base Indenture; and that the Indenture shall not impose any duties upon the Trustee whatsoever with respect to the exercise of any UK Bail-in Power by the Relevant UK Resolution Authority.

Notwithstanding clause (c) of the immediately preceding paragraph, if, following the completion of the exercise of the UK Bail-in Power by the Relevant UK Resolution Authority, the Debt Securities remain outstanding (for example, if the exercise of the UK Bail-in Power results in only a partial write-down of the principal of the Debt Securities), then the Trustee's duties under the Indenture shall remain applicable with respect to the Debt Securities following such completion to the extent that the Issuer and the Trustee shall agree pursuant to a supplemental indenture or an amendment to the Indenture; *provided*, however, that notwithstanding the exercise of the UK Bail-in Power by the Relevant UK Resolution Authority, there shall at all times be a Trustee hereunder pursuant to, and in accordance with, Section 6.09 of the Base Indenture, and the resignation and/or removal of the Trustee and the appointment of a successor trustee shall continue to be governed by Sections 6.10 and 6.11 of the Base Indenture, respectively, including to the extent no additional supplemental indenture or amendment to the Indenture is agreed upon pursuant to the Indenture in the event the Debt Securities remain outstanding following the completion of the exercise of the UK Bail-in Power.

In addition to the right to enter into supplemental indentures pursuant to Sections 9.01 and 9.02 of the Base Indenture, the Issuer and the Trustee may enter into one or more indentures supplemental to the Indenture to modify and amend the terms of the Indenture or the Debt Securities, without the further consent of any Holders, to the extent necessary to give effect to the exercise by the Relevant UK Resolution Authority of the UK Bail-in Power.

Upon the exercise of the UK Bail-in Power by the Relevant UK Resolution Authority with respect to the Debt Securities, the Issuer shall provide a written notice to the Holders through DTC as soon as practicable regarding such exercise of the UK Bail-in Power for purposes of notifying Holders and beneficial owners of the Debt Securities of such occurrence. The Issuer shall also deliver a copy of such notice to the Trustee for information purposes. Any delay or failure by the Issuer in delivering the notices referred to in this paragraph to the Holders or the Trustee shall not affect the validity or enforceability of the UK Bail-in Power.

It is the parties' intention that the Issuer's obligations to indemnify the Trustee in accordance with Section 6.07 of the Base Indenture shall survive any exercise of the UK Bail-in Power by the Relevant UK Resolution Authority.

------

Upon the exercise of any UK Bail-in Power by the Relevant UK Resolution Authority that results in the reduction or cancellation of all, or a portion, of the principal amount of this Global Security and/or the conversion of all, or a portion, of the principal amount of this Global Security into shares or other securities or other obligations of the Issuer or another person, the portion of the principal amount hereof so reduced, cancelled and/or converted shall be endorsed by the Registrar on Schedule B hereto. The principal amount hereof shall be reduced for all purposes by the amount so reduced, cancelled and/or converted.

Subject to applicable law, claims in respect of the Debt Security may not be set off, or be the subject of a counterclaim, by any Holder or by the Trustee in respect of any claims of such Holders to payment of any principal, premium or interest in respect of the Debt Securities or the Indenture, against or in respect of any of its obligations to the Issuer, and every Holder and the Trustee in respect of any claims of such Holders waives, and shall be treated for all purposes as if it had waived, any right that it might otherwise have to set-off, or to raise by way of counterclaim any of its claims in respect of the Debt Securities or the Indenture, against or in respect of any of its obligations to the Issuer. Notwithstanding the preceding sentence, if any of the rights and claims of any Holder are discharged by set-off, such Holder will immediately pay an amount equal to the amount of such discharge to the Issuer or, if applicable, the liquidator or trustee or receiver in the Issuer's bankruptcy and, until such time as payment is made, will hold a sum equal to such amount in trust for the Issuer or, if applicable, the liquidator or trustee or receiver in the Issuer's bankruptcy. Accordingly, such discharge will be deemed not to have taken place.

ANY HOLDER OR BENEFICIAL OWNER OF THE DEBT SECURITIES THAT ACQUIRES THE DEBT SECURITIES IN THE SECONDARY MARKET AND ANY SUCCESSORS, ASSIGNS, HEIRS, EXECUTORS, ADMINISTRATORS, TRUSTEES IN BANKRUPTCY AND LEGAL REPRESENTATIVES OF ANY HOLDER OR BENEFICIAL OWNER OF THE DEBT SECURITIES SHALL BE DEEMED TO ACKNOWLEDGE, AGREE TO BE BOUND BY AND CONSENT TO THE SAME PROVISIONS SPECIFIED HEREIN TO THE SAME EXTENT AS THE HOLDERS OR BENEFICIAL OWNERS OF THE DEBT SECURITIES THAT ACQUIRE THE DEBT 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 DEBT SECURITIES RELATED TO THE UK BAIL-IN POWER, THE BENCHMARK AND THE LIMITED REMEDIES AVAILABLE UNDER THE INDENTURE AND THE DEBT SECURITIES FOR A NON-PAYMENT OF PRINCIPAL AND/OR INTEREST ON THE DEBT SECURITIES.

The Indenture and the Debt Securities may be amended and modified as provided in the Indenture.

Such registration statement, as amended as of its most recent effective date (September 2, 2025), insofar as it relates to the Notes (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, 25.3 and 25.4, is herein called the "Registration Statement."

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

Such registration statement, as amended as of its most recent effective date (September 2, 2025), insofar as it relates to the Notes (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, 25.3 and 25.4, is herein called the "Registration Statement".

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the Registration Statement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) an executed copy of the terms agreement dated September 2, 2025 (the "Terms Agreement"), among
the Company and the several underwriters named therein, which attaches and incorporates therein the underwriting agreement (the "Underwriting Agreement");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) an executed copy of the Base Indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) an executed copy of the Supplemental Indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) copies of the Notes in global registered form (the "Global Notes") as executed by the Company and
authenticated by the Trustee; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) a certificate dated September 10, 2025 of the Secretary of the Company (the "Secretary's
Certificate") having annexed thereto and certified as true, complete and up-to-date copies the following documents:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the Memorandum and Articles of Association of the Company (the "Articles of Association");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) the resolutions passed at the Meeting of the Company's Board of Directors held on January 25, 2024
(the "Board Resolutions"); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) a certificate of good standing relating to the Company dated September 4, 2025 (the "Good Standing
Certificate").

In this opinion letter, the Terms Agreement, the Indenture and the Global Notes are referred to collectively as the "Transaction Documents" or each individually as a "Transaction Document".

In rendering the opinions expressed below we have assumed and not verified:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the genuineness of all signatures, stamps and seals, the authenticity and completeness of all documents
supplied to us and the conformity to the originals of all documents supplied to us as photocopies, facsimile or electronic copies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) that, where a document has been examined by us in draft, specimen or certificated form, it has been or will be
executed in the form of that draft, specimen or certificate;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) that each of the Transaction Documents has been or will be duly authorised, executed and delivered by each of
the parties to such Transaction Documents (other than the Company) and each such party (other than the Company) has the power, capacity and authority to execute, deliver and perform its obligations contained in each of the Transaction Documents to
which it is a party;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) the absence of any other arrangements between any of the parties to any of the Transaction Documents which
modify or supersede any of the terms of any of the Transaction Documents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) (i) the accuracy as to factual matters of each document we have reviewed, including, without limitation, the
accuracy of the representations and warranties contained in the Underwriting Agreement other than those contained in Sections 1(a)(viii), 1(b)(i), 1(b)(ii) and 1(b)(v), (ii) the compliance by each of the parties thereto with their respective
obligations under the Transaction Documents;

------

HSBC Holdings plc, Page 3

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) that no law of any jurisdiction outside England and Wales would render the execution, delivery, issue or
performance of the terms of the Transaction Documents illegal or ineffective and that, insofar as any obligation under the Transaction Documents falls to be performed in any jurisdiction other than England and Wales, its performance will not be
illegal or ineffective by virtue of the laws of that jurisdiction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) that any party or prospective party to the Transaction Documents which is subject to the supervision of any
regulatory authority in the United Kingdom has complied and will comply with the requirements of such regulatory authority in connection with the offering and sale of the Notes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) that where a document is required to be delivered, each party to it has delivered the same without it being
subject to escrow or any other similar arrangement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) that each of the parties to the Transaction Documents has fully complied with its obligations under all
applicable money laundering laws and regulations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) that the binding effect of the Transaction Documents on the parties thereto is not affected by duress, undue
influence or mistake, and no document has been entered into by any of the parties thereto in connection with any unlawful activity;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(k) that all consents, approvals, notices, filings and registrations which are necessary under any applicable laws
or regulations (other than laws or regulations of the United Kingdom) in order to permit the execution, delivery or performance of the Transaction Documents have been or will be duly made or obtained;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(l) that there are no provisions of the laws of any jurisdiction outside England and Wales that would have any
implication for the opinions we express and that, insofar as the laws of any jurisdiction outside England and Wales may be relevant to this opinion letter, such laws have been and will be complied with;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(m) that, save for Article 12 (*Subordination of Debt Securities*) of the Base Indenture (and the
corresponding provision in the Global Notes) and the authorisation and execution by the Company of the Indenture and the Global Notes, which are expressed to be governed by the laws of England and Wales, each of the Transaction Documents constitutes
legal, valid and binding obligations of each of the parties thereto enforceable in accordance with its terms under all applicable laws (including the laws of the State of New York, by which the Transaction Documents are expressed to be governed);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(n) that the choice of the laws of England and Wales to govern Article 12 (*Subordination of Debt Securities*)
of the Base Indenture (and the corresponding provision in the Global Notes) was freely made in good faith by the respective parties and there is no reason for avoiding such choice on the grounds of public policy;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(p) that the information relating to the Company disclosed by our searches on September 10, 2025 at Companies House
at their website at www.companieshouse.gov.uk and by telephone at the Central Registry of Winding up Petitions at the Insolvency and Companies List in London in relation to the Company was then complete, up to date and accurate and has not since
then been materially altered and that such searches did not fail to disclose any material information which had been delivered for registration but did not appear on the website or on the relevant file in London at the time of our search, and that
such oral disclosures did not fail to disclose any material information or any petition for an administration order, dissolution or winding-up order in respect of the Company that has been presented in England

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(s) that the execution and delivery of each of the Transaction Documents by the Company and the exercise of its
rights and performance of its obligations thereunder will (i) materially benefit the Company and that the directors of the Company acted in good faith and in the interests of the Company in approving each of the Transaction Documents and the
transactions contemplated thereby; and (ii) will not conflict with, or result in a breach of, or constitute a default under, or result in the creation of any mortgage, charge or security interest upon any property or assets of the Company or
its subsidiary undertakings under (A) any agreement to which it is a party or to which any of its properties may be subject or (B) any existing applicable law, rule, regulation, judgment, order or decree of any government, governmental
instrumentality or court, having jurisdiction over the Company or its subsidiary undertakings or any of its properties; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(t) that any limit on borrowings to which the Company is subject has not been exceeded, and that the entry into the
Transaction Documents will not cause any such limit on borrowings to be exceeded.

Based on the foregoing, and subject to the further qualifications and limitations set forth below, it is our opinion that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. The Company has been duly incorporated in and registered as a public limited company under the laws of England and Wales. A search of the records of the Registrar of Companies as made public through the www.companieshouse.gov.uk website at 10:17 a.m. BST on September 10, 2025 and an oral enquiry made to the Central Registry of Winding up Petitions at the Insolvency and Companies List at approximately 10:15 a.m. BST on September 10, 2025 revealed no petition, order or resolution for the winding up of the Company and no petition for, and no notice of appointment of, a receiver or administrator, provided that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the searches with Companies House referred to above are not conclusively capable of revealing whether or not
(i) a winding up order has been made in respect of a company or a resolution passed for the winding up of a company, or (ii) an administration order has been made in respect of a company, or (iii) a receiver, administrative receiver,
administrator, liquidator or similar officer has been appointed in respect of a company, since notice of these matters might not be filed with Companies House immediately and, when filed, might not be made available through the website or entered on
the files of Companies House relating to insolvency details with respect to the relevant company immediately. In addition, such searches are not capable of revealing, prior to the making of the relevant order, whether or not a winding up petition or
a petition for an administration order has been presented; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the enquiry at the Central Registry of Winding up Petitions at the Insolvency and Companies List referred to
above relates only to a compulsory winding up and is not capable of revealing conclusively whether or not a winding up petition in respect of a compulsory winding up has been presented since details of the petition may not have been entered on the
records of the Central Registry of Winding up Petitions immediately or, in the case of a petition presented to a County Court, may not have been notified to the Central Registry and entered on such records at all, and the response to an enquiry only
relates to the period of six months prior to the date when the enquiry was made. We have not made enquiries of any County Court as to whether a petition for the appointment of an administrator has been presented to, or an administration order has
been made by, any County Court against the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. The Company possessed, as at the time of execution, the corporate power to enter into and perform its obligations under the Base Indenture and the Company possesses the corporate power to enter into and perform its obligations under the Supplemental Indenture and the Global Notes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. The Base Indenture and the Supplemental Indenture have each been duly authorised, executed and delivered by the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. The Global Notes have been duly authorised, issued and executed by the Company and, when delivered in accordance with the Terms Agreement, the obligations assumed by the Company under Article 12 (*Subordination of Debt Securities*) of the Base Indenture (and the corresponding provision in the Global Notes) constitute valid, binding and enforceable obligations of the Company.

The expression "enforceable" as used in paragraph 4 above means that the obligations assumed by the relevant party under the relevant document are of a type which English courts enforce. The foregoing does not mean that those obligations will necessarily be enforced in all circumstances in accordance with their terms. In particular, but without limitation:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The opinions set forth above as regards the binding effect and validity of the obligations and their
enforceability against contracting parties is subject to all limitations resulting from the laws of bankruptcy, administration, liquidation, insolvency, fraudulent transfer, reorganisation, moratorium, suretyship or any similar laws of general
application affecting creditors' rights (including, for the avoidance of doubt, the provisions of the Banking Act 2009).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Enforcement may be limited by general principles of equity. For example, equitable remedies may not be
available where damages are considered to be an adequate remedy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Where any obligations of any person are to be performed or observed in jurisdictions outside England and Wales,
or by a person subject to the laws of a jurisdiction outside England and Wales, such obligations may not be enforceable under the laws of England and Wales to the extent that the performance or observance thereof would be illegal or contrary to
public policy under the laws of any such jurisdiction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) To the extent that any transactions, dealings or arrangements in connection with any Transaction Document are
restricted or prohibited by United Nations, European Union (the "EU") or United Kingdom sanctions or restrictive measures implemented or effective in the United Kingdom, such Transaction Document or any other affected Transaction
Document may be unenforceable or void.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) Any provision providing that any calculation, certification, determination, notification, minute or opinion
will be conclusive and binding will not be effective if such calculation, certification, determination, notification, minute or opinion is fraudulent or made on an unreasonable or arbitrary basis or in the event of manifest error despite any
provision to the contrary and it will not necessarily prevent judicial enquiry into the merits of any claim by any party thereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) Where any person is vested with a discretion, or may determine any matter in its opinion, the laws of England
and Wales may require that such discretion is exercised reasonably or that such opinion is based on reasonable grounds.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) Enforcement of rights may be or become limited by prescription or by lapse of time or may become subject to
defences of set-off or counterclaim.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) We have not undertaken any consideration, analysis or assessment of whether the National Security and
Investment Act 2021 (the "NS&IA") may or will apply to any of the transactions contemplated by the Transaction Documents for the purposes of the opinions in this letter. We express no opinion on the application or potential
application of the NS&IA in relation to the Company or any transaction contemplated by the Transaction Documents.

The opinions set out above are given on the basis of, and are limited to, the laws of England and Wales in force as at the date of this opinion letter (taking into account the effect of the Agreement on the withdrawal of the United Kingdom of Great Britain and Northern Ireland from the EU and the European Atomic Energy Community and the EUWA), as currently applied by the courts in England and Wales, and are given on the basis that this opinion letter and any non-contractual obligations arising out of or in connection with it will be governed by and construed in accordance with the laws of England and Wales. On 31 January 2020, the United Kingdom ceased to be a member of the EU. By virtue of Sections 1A and 1B of the EUWA, EU law continued to be applicable in the United Kingdom for the duration of the implementation period set out in Section 1A(6) of the EUWA (the "Transition Period"). After the Transition Period, pursuant to Sections 2 to 4 of the EUWA, certain EU laws in effect immediately before the end of the Transition Period form part of English law. However, EU law otherwise ceased to be applicable in the United Kingdom and thus does not form part of English law on and after 1 January 2021. The Retained EU Law (Revocation and Reform) Act 2023 came into effect on 1 January 2024 and, among other amendments, repealed Section 4 of the EUWA and further restricted the scope of retained EU law in United Kingdom domestic law (now renamed 'assimilated law'). We express no opinion in this letter on the effect of EU law in the United Kingdom or on EU law itself.
