ARTICLE II 

$2,350,000,000 6.250% PERPETUAL SUBORDINATED CONTINGENT CONVERTIBLE SECURITIES 

(CALLABLE MARCH 23, 2023 AND EVERY FIVE YEARS THEREAFTER) 

SECTION 2.01. Creation of Series; Establishment of Form. 

(a) There is hereby established a new series of Contingent Convertible Securities under the Base Indenture entitled the “$2,350,000,000
6.250% Perpetual Subordinated Contingent Convertible Securities (Callable March 23, 2023 and Every Five Years Thereafter).” 
 (b)
The Securities shall be issued initially in the form of one or more registered Global Securities that shall be deposited with DTC and registered in its name or its nominee and executed and delivered in substantially the form attached hereto as
Exhibit A. DTC shall be the Depository pursuant to Section 3.01 of the Base Indenture. 
 (c) The Company
shall issue the Securities in an aggregate principal amount of $2,350,000,000. The Company may from time to time, without the consent of the Holders, 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 Sixth 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 shall be effected through the book-entry systems
maintained by DTC. 
 (e) The Securities shall not have a sinking fund. 

(f) The Securities shall be issued on March 23, 2018 (the “Issue Date”). 

  
 16 

 (g) The Securities shall have no fixed maturity and shall not be redeemable except as provided in
Sections 2.08, 2.09 and 2.10 hereof. 
 (h) The interest rate on the Securities shall be determined as set forth in
Section 2.02(a) hereof. 
 (i) The Securities shall be issued in denominations of $200,000 in principal amount and integral
multiples of $1,000 in excess thereof. 
 (j) The denomination of each interest in a 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 equal such Global Security’s outstanding principal amount. Following an Automatic
Conversion, the principal amount of each Security shall equal zero, but the Tradable Amount of the book-entry interests in each Security shall remain unchanged as a result of the Automatic Conversion. 

SECTION 2.02. Interest. 

(a) From (and including) the Issue Date to (but excluding) March 23, 2023, the interest rate on the Securities shall be 6.250% per annum.
From (and including) each Reset Date to (but excluding) the next following Reset Date, the applicable per annum interest rate shall be equal to the sum of the applicable Mid-Market Swap Rate on the relevant
Reset Determination Date and 3.453%. Subject to Sections 2.03 and 2.04, interest, if any, shall be payable in two equal semi-annual installments in arrear on March 23 and September 23 of each year (each, an “Interest Payment
Date”); provided that if such 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. Subject to Sections 2.03 and 2.04, interest on the Securities, if any, shall be computed and payable in arrear and on the basis of a year of 360 days consisting of twelve (12) months of thirty (30) days each and, in the case of
an incomplete month, the actual number of days elapsed. The first date on which interest may be paid shall be September 23, 2018 for the period commencing on (and including) the Issue Date and ending on (but excluding) September 23, 2018.
If a date of redemption or repayment is not a Business Day, the Company may pay interest (if any) together with the principal on the next succeeding Business Day; provided that interest shall not accrue during the period from and after the
date of redemption. The “Regular Record Date” shall be the close of business (local time in the place of the Register) on the fifteenth (15th) calendar day prior to the relevant
Interest Payment Date. 
 (b) If any Reset Date is not a Business Day, the Reset Date shall occur on the next succeeding Business Day. For
the avoidance of doubt, if the Reset Date is not a Business Day and accordingly the Reset Date occurs on the next Business Day (the “Adjusted Reset Date”), then the equal semi-annual payment of interest (if paid) on the next
Interest Payment Date shall reflect interest for the entire interest period (including any portion of such interest period occurring between the originally scheduled Reset Date and the Adjusted Reset Date) at the interest rate determined based on
the Adjusted Reset Date, and not at the interest rate that applied to the immediately preceding semi-annual interest period. In addition and for the avoidance of doubt, in connection with any optional redemption of the Securities pursuant to
Section 2.08, if the Reset Date is not a Business Day, as described above, the Company may pay the interest (if any) together with the principal on the Adjusted Reset Date, but interest on that payment shall not accrue during the period from
and after the last Interest Payment Date. 
 (c) The Company shall promptly give notice of the determination of the Alternative Base Rate and
any adjustment factors to the Trustee, the Agent and the Holders. 

  
 17

Beneficial Owner) (i) waives any and all claims, in law and/or in equity, against the Trustee and the Agent for, agrees not to initiate a suit against the Trustee and the Agent in respect of, and agrees that neither the Trustee nor the Agent
shall be liable for, the determination of or the failure to determine any Alternative Base Rate (including any adjustments thereto) and any losses suffered in connection therewith, and (ii) agrees that neither the Trustee nor the Agent shall
have any obligation to determine any Alternative Base Rate (including any adjustments thereto), including in the event of any failure by the Company to determine any Alternative Base Rate. 

(e) All determinations and any calculations made by the Calculation Agent for the purposes of calculating the applicable Mid-Market Swap Rate shall be conclusive and binding on the Holders, the Company, the Trustee and the Paying Agent, absent manifest error. The Calculation Agent shall not be responsible to the Company, the Holders
or any third party for any failure of the Reference Banks to provide quotations as requested of them or as a result of the Calculation Agent having acted on any quotation or other information given by any Reference Bank which subsequently may be
found to be incorrect or inaccurate in any way. 
 (f) In addition to any other restrictions on payments of principal and interest contained
in this Sixth Supplemental Indenture, 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. 
 SECTION 2.03.
Interest Payments Discretionary. 
 (a) 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 (the “Discretionary Interest
Payment Right”). 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. For the avoidance of doubt, 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. 
 (b) Interest shall
only be due and payable on an Interest Payment Date to the extent it is not cancelled or deemed to have been cancelled (in each case, in whole or in part) in accordance with the provisions set forth in Sections 2.03(a) and 2.04, and any
interest cancelled or deemed to have been cancelled (in each case, in whole or in part) pursuant to such Sections shall not be due and shall not accumulate or be payable at any time thereafter, and Holders and Beneficial Owners shall have no
rights thereto or to receive any additional interest or compensation as a result of such cancellation or deemed cancellation.

 SECTION 2.04. Restriction on Interest Payments. 

(a) Without prejudice to the provisions of Section 2.03 or the prohibition contained in Article 141(2) of CRD (and any implementation of
such provision in the UK or, as the case may be, any succeeding provision amending or replacing such Article or any such implementing provision) on the making of payments on the Securities before the Maximum Distributable Amount has been calculated,
subject to the extent permitted in clause (b) below 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: 

(i) the amount of Relevant Distributions exceeds the amount of Distributable Items as of such Interest Payment Date; 

(ii) the aggregate of (x) the interest amount payable in respect of the Securities and (y) the amounts of any
distributions of the kind referred to in Article 141(2) of CRD (and any implementation of such provision in the UK or, as the case may be, any succeeding provision amending or replacing such Article or any such implementing provision) exceeds the
Maximum Distributable Amount (if any) applicable to the Company as of such Interest Payment Date; 
 (iii) the Solvency
Condition is not satisfied in respect of such interest payment; or 
 (iv) the Relevant Regulator orders the Company to
cancel (in whole or in part) the interest otherwise payable on such Interest Payment Date; 
 (b) 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 restriction of clause (a) above. For the avoidance
of doubt, the portion of interest not paid on the relevant Interest Payment Date shall be deemed to have been cancelled and thus shall not be due and payable on such Interest Payment Date. 

SECTION 2.05. Agreement to Interest Cancellation. By its acquisition of the Securities, each Holder (which, for these purposes
includes each Beneficial Owner) acknowledges and agrees that: 
 (a) 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 to have
been cancelled (in whole or in part), including as a result of the Distributable Items or the Maximum Distributable Amount being exceeded, failing to satisfy the Solvency Condition under Section 2.04 or an order from the Relevant Regulator; and

 (b) a cancellation or deemed cancellation of interest (in each case, in whole or in part) in accordance with the terms of the Indenture
and the Securities shall not constitute a default in payment or otherwise under the terms of the Securities or the Indenture. 

SECTION 2.06. Notice of Interest Cancellation. If practicable, the Company shall provide notice of any cancellation or deemed
cancellation of interest (in each case, in whole or in part) to the Holders, in the case of Global Securities, via DTC (or, if the Securities are definitive Securities, to the Holders at their addresses shown on the Register) and to the Trustee and
the Paying Agent directly on or prior to the relevant Interest Payment Date. If practicable, the Company shall endeavor to do so at least five (5) Business Days prior to the relevant Interest Payment Date. Failure to provide such notice shall
have no impact on the effectiveness of, or otherwise invalidate, any such cancellation or deemed cancellation of interest (and accordingly, such interest shall not be due and payable, as provided in Section 2.03), or give the Holders or
Beneficial Owners any rights as a result of such failure. 

  
 19 

 SECTION 2.07. Payment of Principal, Interest and Other Amounts. Payments of principal
of and interest, if any, on the Securities shall be made in dollars and such payments on Securities represented by a Global Security shall be made through one or more Paying Agents appointed under the Base Indenture to DTC or its nominee, as the
Holder or Holders of the Global Security. Initially, the Paying Agent shall be HSBC Bank USA, National Association. The Company may change the Paying Agent without prior notice to the Holders, and in such an event the Company may act as Paying
Agent. Payments of principal of and interest on the Securities represented by a 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. 
 SECTION 2.08. Optional Redemption. Subject to the limitations specified in
Section 2.12, the Company may, at the Company’s option in its sole discretion, redeem the Securities, in whole (but not in part), on any 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 to have been cancelled as described in Sections 2.03 and 2.04) to (but excluding) the date fixed for redemption. 

SECTION 2.09. Optional Tax Redemption. 

(a) Subject to Section 2.12, the Company may, at the Company’s option in its sole discretion, 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 to have been cancelled as described in
Sections 2.03 and 2.04) to (but excluding) the date fixed for redemption, if, at any time, the Company determines that as a result of a change in, or amendment to, the laws of a Taxing Jurisdiction, including any treaty to which the relevant
Taxing Jurisdiction is a party, or a change in an official application or interpretation of those laws on or after the Issue Date, including a decision of any court or tribunal that becomes effective on or after the Issue Date: 

(i) on a subsequent date for the payment of interest on the Securities the Company would be required to pay any Additional
Amounts; 
 (ii) if the Company were to seek to redeem the Securities on a subsequent date (for which purpose no
consideration shall be given as to whether or not the Company would otherwise be entitled to redeem the Securities), the Company would be required to pay any Additional Amounts (notwithstanding the Company having made such endeavors as the Company
considers reasonable); 
 (iii) on a subsequent date for the payment of interest on the Securities, interest payments (or the
Company’s funding costs as recognized in the Company’s accounts) under, or with respect to, the Securities are no longer fully deductible for UK corporation tax purposes; 

(iv) the Securities would no longer be treated as loan relationships for UK tax purposes; 

(v) would, as a result of the Securities being in issue, result in the Company not being able to have losses or deductions set
against the profits or gains, or profits or gains offset by the losses or deductions, of companies with which it is or would otherwise be so grouped for applicable UK tax purposes (whether under the group relief system current as of the Issue Date
or any similar system or systems having like effect as may from time to time exist); 

  
 20 

 (vi) a future write-down of the principal amount of the Securities or conversion
of the Securities into the Ordinary Shares would result in a UK tax liability, or the receipt of income or profit which would be subject to UK tax, which would not otherwise have been the case as of the Issue Date; or 

(vii) the Securities or any part thereof become treated as a derivative or an embedded derivative for UK tax purposes 

(each such change (or deemed change) in tax law or regulation or the official application or interpretation thereof, a “Tax Event”). 

(b) Subject only to the Company’s obligation to use such endeavors as provided in Section 2.09(a)(ii), it shall be sufficient for the
Company to deliver to the Trustee an Officer’s Certificate stating that a Tax Event has occurred and is continuing and setting out the details thereof, as well as any opinion or certificate of an independent legal adviser on which such
Officer’s Certificate is based. 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 shall be conclusive and binding on the Holders and Beneficial Owners. 
 SECTION 2.10. Capital Disqualification Event
Redemption. 
 Subject to Section 2.12, the Company may, at the Company’s option in its sole discretion, 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 to have been cancelled as
described in Sections 2.03 and 2.04) to (but excluding) the date fixed for redemption, if the Company determines, at any time after the Issue Date, there is a change in the regulatory classification of the Securities that results or shall
result in either their (i) exclusion in whole or in part from the HSBC Group’s regulatory capital (other than as a consequence of an Automatic Conversion); or (ii) reclassification in whole or in part as a form of the HSBC
Group’s regulatory capital that is lower than additional Tier 1 capital (a “Capital Disqualification Event”). 

SECTION 2.11. Notice of Redemption. 

(a) Before the Company may redeem the Securities pursuant to Section 2.08, 2.09 or 2.10, the Company shall deliver via DTC (or, if the
Securities are definitive Securities, to the Holders at their addresses shown on the Register) prior notice of not less than thirty (30) days, nor more than sixty (60) days to the Holders; provided, however, that in the case
of a Tax Event, no notice of redemption shall be given earlier than 90 days prior to the earliest date on which the Company would be obliged to pay Additional Amounts were a payment in respect of the Securities then due. Such notice shall specify
the 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 clauses (b), (c) and (d) of this Section 2.11. 

(b) If the Company has delivered a notice of redemption pursuant to clause (a) of this Section 2.11, but as of the date
specified for redemption in such notice, the Solvency Condition is not satisfied in respect of the relevant redemption payment, 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 the Company has delivered a notice of redemption pursuant to
clause (a) of this Section 2.11, but prior to the payment of the redemption amount with respect to such redemption a Capital Adequacy Trigger Event occurs, such redemption notice shall be automatically rescinded and shall be of no
force and effect, no payment in respect of the redemption amount shall be due and payable (and, for the avoidance of doubt, an Automatic Conversion shall occur after such Capital Adequacy Trigger Event pursuant to Section 2.15(a)). 

  
 21 

 (d) If the Company has delivered a notice of redemption pursuant to clause (a) of this
Section 2.11, but prior to the payment of the redemption amount with respect to such redemption the Relevant UK Resolution Authority exercises its UK Bail-in Power with respect to the Company, 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. 

(e) If any of the events specified in clauses (b), (c) and (d) of this Section 2.11 occurs, the Company shall promptly deliver
notice to the Holders, in the case of Global Securities, via DTC (or, if the Securities are definitive Securities, to the Holders at their addresses shown on the Register) and to the Trustee and the Paying Agent directly, specifying the occurrence
of the relevant event. 
 SECTION 2.12. Limitations on Redemption. Notwithstanding any other provision of the Sixth Supplemental
Indenture, the Company may redeem the Securities pursuant to Sections 2.08, 2.09 and 2.10 only if (i) the Company has obtained the Relevant Supervisory Consent, (ii) in the case of a Special Event pursuant to Section 2.09 or
Section 2.10 only, prior to the fifth anniversary of the Issue Date, if the Relevant Rules so oblige, the Company has demonstrated to the satisfaction of the Relevant Regulator that (x) the Special Event was not reasonably foreseeable at
the Issue Date and (y) in the case of a Tax Event, such Tax Event was material, (iii) the Company has complied with any alternative or additional pre-conditions to redemption, as applicable, set out
in the Relevant Rules and (iv) the Company has provided notice in accordance with Section 2.11. 
 SECTION 2.13. Cancelled
Interest Not Payable Upon Redemption. Any interest payments that have been cancelled or deemed to have been cancelled pursuant to Sections 2.03 or 2.04 shall not be payable if the Securities are redeemed pursuant to Section 2.08, 2.09
or 2.10. 
 SECTION 2.14. Purchases. Notwithstanding any other provision of the Indenture, including Section 6.05 of the
Base Indenture, members of the HSBC Group may purchase, repurchase or otherwise acquire any of the Securities then Outstanding at the same or differing prices in the open market, negotiated transactions or otherwise without giving prior notice to or
obtaining any consent from Holders, in accordance with the Relevant Rules and subject to obtaining the Relevant Supervisory Consent. For the avoidance of doubt, the Securities may be repurchased by members of the HSBC Group for market-making
purposes in accordance with any permission given by the Relevant Regulator pursuant to the Relevant Rules (including, without limitation, Article 29(3) of Commission Delegated Regulation (EU) No. 241/2014) within the limits prescribed in such
permission. 
 SECTION 2.15. Automatic Conversion upon Capital Adequacy Trigger Event. 

(a) If a Capital Adequacy Trigger Event has occurred, then the Automatic Conversion shall occur without delay, but no later than one
(1) month following the date on which it is determined such Capital Adequacy Trigger Event has occurred (such date, the “Conversion Date”). Whether a Capital Adequacy Trigger Event has occurred at any time shall be determined
by the Company, the Relevant Regulator or any agent of the Relevant Regulator appointed for such purpose by the Relevant Regulator. Effective upon, and following, a Capital Adequacy Trigger Event, other than any amounts payable in the case of the
Company’s winding-up or the appointment of an administrator for its administration pursuant to Section 5.01, Holders and Beneficial Owners shall not have any rights against the Company with respect
to repayment of the principal amount of the Securities or payments of interest or any other amount on, or in respect of, the Securities, in each case that is not due and payable, which liabilities shall be automatically

  
 22 

 
released. Accordingly, the principal amount of the Securities shall equal zero at all times thereafter and any interest shall be cancelled or deemed to have been cancelled pursuant to
Section 2.03 at all times thereafter, including 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, and shall not be due and
payable. Although the principal amount of each Security shall equal zero after a Capital Adequacy Trigger Event, for the avoidance of doubt, the Tradable Amount shall remain unchanged as a result of the Automatic Conversion. 

Effective upon, and following, the Conversion Date, all of the Company’s obligations under the Securities shall be irrevocably and
automatically released in consideration of the Company’s issuance of the Conversion Shares to the Conversion Shares Depository (or the relevant recipient pursuant to this Section 2.15), and under no circumstances shall such released
obligations be reinstated. 
 While any Security remains Outstanding, the Company shall at all times keep available for issue, free from
preemptive or other preferential rights, sufficient ordinary shares to enable an Automatic Conversion to be satisfied in full. 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 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, distributions or payments, the entitlement to which
falls prior to the Conversion Date. 
 The Conversion Shares shall initially be registered in the name of the Conversion Shares Depository
(or the relevant recipient pursuant to this Section 2.15) (which shall hold the Conversion Shares on behalf of the Holders and Beneficial Owners), 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). 

The Conversion Shares Depository (or the relevant recipient pursuant to this Section 2.15) shall hold the Conversion Shares on behalf of
the Holders and Beneficial Owners, who shall be entitled to direct the Conversion Shares Depository or such other relevant recipient, as applicable, to exercise on their behalf all rights of a Shareholder (including voting rights and rights to
receive dividends); provided, however, that Holders and Beneficial Owners shall not have any rights 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 2.18. 
 The Securities shall remain in existence until the
applicable Cancellation Date for the sole purpose of evidencing 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) in accordance with the terms of the Securities. 
 With effect from the Conversion Date, Holders
and Beneficial Owners shall have recourse only to the Conversion Shares Depository (or to the relevant recipient pursuant to this Section 2.15) 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. If the Company fails to issue and deliver the Conversion Shares to the Conversion Shares Depository in accordance with the terms of
the Securities and the Indenture, the only right of the Holders and Beneficial Owners against the Company shall be to claim to have such Conversion Shares issued to the Conversion Shares Depository. 

  
 23 

 If the Company has been unable to appoint a Conversion Shares Depository, it shall effect, by
means it deems reasonable in the circumstances (including, without limitation, issuance of the Conversion Shares to another nominee or to the Holders directly), the issuance and/or delivery of the Conversion Shares or Conversion Shares Offer
Consideration, as applicable, to the Holders, and such issuance shall irrevocably and automatically release all of the Company’s obligations under the Securities as if the Conversion Shares had been issued to the Conversion Shares Depository.

 (b) The Company shall (a) immediately inform the Relevant Regulator of the occurrence of a Capital Adequacy Trigger Event and
(b) deliver an Automatic Conversion Notice on or as soon as practicable after the date on which it is determined such Capital Adequacy Trigger Event has occurred. 

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 DTC (or, if the Securities are definitive Securities, to the Trustee). 
 The Company shall request that DTC, pursuant to the
applicable rules and operating procedures of DTC then in effect, transmit the Automatic Conversion Notice to the direct participants of DTC holding the Securities at such time. 

Upon delivery of the Automatic Conversion Notice, the Company shall deliver to the Trustee and the Paying Agent 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
and the Paying Agent are each 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 Capital Adequacy Trigger Event Officers’ Certificate shall be conclusive and binding on the Trustee, the Paying Agent, the Holders and the Beneficial Owners. 

(c) Within ten (10) Business Days following the Conversion Date, the Company shall deliver a Conversion Shares Offer Notice. 

(d) The procedures set forth in this Section 2.15 are subject to change to reflect changes in DTC’s practices, and the Company may
make changes to the procedures set forth in this Section 2.15 to the extent reasonably necessary, in the opinion of the Company, to reflect such changes in DTC’s practices. 

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

(f) Notwithstanding anything to the contrary contained in the Indenture or the Securities, once the Company has delivered an Automatic
Conversion Notice following the occurrence of a Capital Adequacy Trigger Event (or following an Automatic Conversion (if sooner)), (i) subject to the right of Holders and Beneficial Owners pursuant to Section 4.03 in the event of a failure
by the Company to issue and deliver any Conversion Shares to the Conversion Shares Depository on the Conversion Date, the Holders and Beneficial Owners shall have no rights whatsoever under the Indenture or the Securities to instruct the Trustee or
the Paying Agent 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 2.15(f), 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 or unless the Trustee
or the Paying Agent is instructed in writing by the Company to act otherwise. 

  
 24 

 (g) Neither the Trustee nor the Paying Agent shall be liable with respect to (i) the
calculation or accuracy of the End-point 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 End-point CET1 Ratio calculations of a Capital Adequacy Trigger Event to DTC, the Holders or the Beneficial Owners or (iii) any aspect of the Company’s
decision to deliver an Automatic Conversion Notice or the related Automatic Conversion. 
 (h) Notwithstanding any other provision herein, by
its acquisition of the Securities, each Holder (which, for these purposes, includes each Beneficial Owner) (i) consents to all of the terms and conditions of the Securities, including (x) the occurrence of a Capital Adequacy Trigger Event
and any related Automatic Conversion following a Capital Adequacy Trigger Event and (y) the appointment of the Conversion Shares Depository (or to the relevant recipient pursuant to Section 2.15), the issuance of the Conversion Shares to
the Conversion Shares Depository (or to the relevant recipient pursuant to Section 2.15) and the potential sale of the Conversion Shares pursuant to a Conversion Shares Offer, (ii) acknowledges and agrees that effective upon, and
following, a Capital Adequacy Trigger Event, other than any amounts payable in the case of the Company’s winding-up or the appointment of an administrator for its administration pursuant to
Section 5.01, no Holder shall have any rights against the Company with respect to repayment of the principal amount of the Securities or payment of interest or any other amount on or in respect of such Securities, in each case that is not due
and payable, which liabilities of the Company shall be automatically released, (iii) acknowledges and agrees that events in, and related to, clause (i) may occur without any further action on the part of such Holder, the Trustee or the
Paying Agent, (iv) authorizes, directs and requests DTC and any direct participant in DTC or other intermediary through which it holds such Securities to take any and all necessary action, if required, to implement the Automatic Conversion
without any further action or direction on the part of such Holder, the Trustee or the Paying Agent and (v) 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. 

SECTION 2.16. Conversion Shares. 

(a) The number of Conversion Shares to be issued to the Conversion Shares Depository (or to the relevant recipient pursuant to
Section 2.15) on the Conversion Date shall equal the quotient obtained by dividing the (i) aggregate principal amount of the Securities then Outstanding immediately prior to the Automatic Conversion on the Conversion Date (the
“Outstanding Amount”) by (ii) the Conversion Price, rounded down, if necessary, to the nearest whole number of Conversion Shares. The number of Conversion Shares to be held by the Conversion Shares Depository for the benefit of
a Holder shall equal the product obtained by multiplying (i) the number of Conversion Shares thus calculated by (ii) the quotient obtained by dividing (x) the Tradable Amount held by such Holder on the Conversion Date by (y) the
Outstanding Amount, such product to be 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. 
 (b) Subject to Section 3.05 (including the conditions specified therein), 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 shall be issued by the Approved Entity to the Conversion Shares Depository instead of Conversion Shares with the same effect as if Conversion Shares
had been issued pursuant to Section 2.16(a). 

  
 25 

 SECTION 2.17. Conversion Shares Offer. 

(a) Following the occurrence of an Automatic Conversion, the Company, in its sole and absolute discretion, may elect in the Conversion Shares
Office Notice that the Conversion Shares Depository make an offer of all or some of the Conversion Shares to all or some of the Shareholders at a cash price per Conversion Share equal to the Conversion Shares Offer Price (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. 

(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 any interest in the Conversion Shares to the Conversion Shares Depository (or the relevant recipient pursuant to Section 2.15) in order for the Conversion Shares Depository (or the relevant recipient pursuant to
Section 2.15) to conduct the Conversion Shares Offer), including the fees of the Conversion Shares Offer Agent, if any. 
 (c) Upon
completion of the Conversion Shares Offer, the Company or the Conversion Shares Depository shall provide notice to the Holders of the composition of the Conversion Shares Offer Consideration (and the Cash Component thereof, if any) 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 and the Paying Agent directly and to the Holders, in the case of Global Securities, via DTC (or, if the Securities are definitive Securities, to the Holders at their addresses shown on the 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) 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) The Cash Component of any Conversion Shares Offer Consideration shall be payable by the
Conversion Shares Depository to the Holders and Beneficial Owners (or the custodian, nominee, broker or other representative thereof) of the Securities whether or not the Solvency Condition is satisfied. 

(e) If the Company elects, in its sole and absolute discretion, that a Conversion Shares Offer be conducted, each Holder (which, for these
purposes, includes each Beneficial Owner) by its acquisition of the Securities, shall (i) consent to (x) any Conversion Shares Offer and to the Conversion Shares Depository’s using the Conversion Shares to settle any Conversion Shares
Offer in accordance with the terms of the Securities, notwithstanding that such Conversion Shares are held by the Conversion Shares Depository on behalf of Holders and Beneficial Owners 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 agree that (x) the Company, the Conversion Shares Depository
(or the relevant recipient pursuant to Section 2.15) and the Conversion Shares Offer Agent, if any, may take any and all actions necessary to conduct the Conversion Shares Offer in accordance with the terms of the Securities, and (y) none
of the Company, the Trustee, the Paying Agent, 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). 

  
 26 

 SECTION 2.18. Settlement Procedure. 

(a) Delivery of the Conversion Shares or Conversion Shares Offer Consideration, as applicable, to the Holders and Beneficial Owners shall be
made in accordance with the procedures set forth in this Section 2.18, which remain subject to change to reflect changes in DTC’s practices. 

(b) On the Suspension Date, the Company shall deliver an Automatic Conversion Settlement Request Notice. 

(c) 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 Offer Consideration, as applicable, unless such Holders or Beneficial Owners (or the custodian, nominee, broker or other representative thereof) deliver the applicable Automatic Conversion 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. 
 (d) With
respect to any Global Securities, the Automatic Conversion Settlement Notice must be given in accordance with the respective standard procedures of DTC (which may include, without limitation, delivery of the notice to the Conversion Shares
Depository by electronic means) and in a respective form acceptable to DTC and the Conversion Shares Depository. With respect to any definitive Securities, the Automatic Conversion Settlement Notice must be delivered to the specified office of the
Conversion Shares Depository together with the relevant Securities. 
 (e) Subject to satisfaction of the requirements and limitations set
forth in this Section 2.18 and provided that the Automatic Conversion Settlement Notice and the relevant Securities, if applicable, are delivered, the Conversion Shares Depository shall deliver the relevant Conversion Shares or
Conversion Shares Offer Consideration, as applicable, on the applicable Settlement Date to the Holder or Beneficial Owner (or custodian, nominee, broker or other representative thereof) having completed the relevant Automatic Conversion Settlement
Notice and in accordance with the instructions given in such Automatic Conversion Settlement Notice. 
 (f) Each Automatic Conversion
Settlement Notice shall be irrevocable. The Conversion Shares Depository shall determine, in its sole and absolute discretion, whether any Automatic Conversion 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 an Automatic Conversion Settlement Notice (and the relevant Securities, if applicable) the Conversion
Shares Depository shall be entitled to treat such Automatic Conversion Settlement Notice as null and void. 
 (g) Neither the Company, nor
any member of the HSBC Group, shall be liable for any taxes or duties (including, without limitation, any capital, stamp, issue and registration or transfer taxes or duties) arising on conversion or that may arise or be paid as a consequence of the
issue and delivery of Conversion Shares following an Automatic Conversion. The Holder or Beneficial Owner must pay any taxes or duties (including, without limitation, any capital, stamp, issue and registration and /or transfer taxes or duties)
arising on conversion in connection with the issue and delivery of Conversion Shares to the Conversion Shares Depository on behalf of such Holder or Beneficial Owner, and such Holder or 

  
 27 

 
Beneficial Owner must pay all, if any, such taxes or duties arising by reference to any disposal or deemed disposal of such Holder or Beneficial Owner’s Securities or interest therein. Any
taxes or duties arising on delivery or transfer of Conversion Shares to a purchaser in any Conversion Shares Offer shall be payable by the relevant purchaser of those Conversion Shares. 

(h) The Conversion Shares and any Conversion Shares Component shall not be available for delivery (i) to, or to a nominee for, Clearstream
Luxembourg or Euroclear or any other person providing a clearance service within the meaning of Section 96 of the Finance Act 1986 of the United Kingdom or (ii) to a person, or nominee or agent for a person, whose business is or includes
issuing depository receipts within the meaning of Section 93 of the Finance Act 1986 of the United Kingdom, in each case at any time prior to the “abolition day” as defined in Section 111(1) of the Finance Act 1990 of the
United Kingdom, or, if earlier, such other time at which the Company, in its absolute discretion, determines that no charge under Section 67, 70, 93 or 96 of the Finance Act 1986 or any similar charge (under any successor legislation) would
arise as a result of such delivery or (iii) to the CREST account of such a person described in (i) or (ii). 
 (i) The Company may
make changes to the procedures set forth in this Section 2.18 to the extent such changes are reasonably necessary, in the opinion of the Company, to effect the delivery of the Conversion Shares or Conversion Shares Offer Consideration, as
applicable, to the Holders and Beneficial Owners. 
 SECTION 2.19. Failure to Deliver an Automatic Conversion Settlement
Notice. If any Holder or Beneficial Owner (or custodian, nominee, broker or other representative thereof) fails to deliver an Automatic Conversion 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 Conversion Shares Offer Consideration, as applicable, until an Automatic
Conversion Settlement Notice (and the relevant Securities, if applicable) is so delivered; provided, however, that the relevant Securities shall be cancelled on the Final Cancellation Date, and any Holder or Beneficial Owner (or
custodian, nominee, broker or other representative thereof) delivering an Automatic Conversion Settlement Notice after the Notice Cut-off Date shall be required to provide evidence of its entitlement to the
relevant Conversion Shares or Conversion Shares Offer Consideration, as applicable, satisfactory to the Conversion Shares Depository in its sole and absolute discretion in order to receive delivery of such Conversion Shares or Conversion Shares
Offer Consideration, as applicable. The Company shall have no liability to any Holder or Beneficial Owner for any loss resulting from such Holder or Beneficial Owner’s failure to receive any Conversion Shares or 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 an Automatic Conversion
Settlement Notice (and the relevant Securities, if applicable) on a timely basis or at all. 
 SECTION 2.20. Agreement with Respect
to the Exercise of the UK Bail-in Power. 
 (a) By its acquisition of the Securities, each Holder
(which, for these purposes, includes each Beneficial Owner): 
 (i) acknowledges, accepts, consents and agrees,
notwithstanding any other term of the Securities, the Indenture or any other agreements, arrangements or understandings between the Company 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 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 Company’s or another Person’s 

  
 28 

 
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 Securities or the Indenture; (iii) the cancellation of the Securities; and/or (iv) the amendment or alteration of the redemption date of the Securities or amendment of the amount of
interest payable on the Securities, or the Interest Payment Dates, including by suspending payment for a temporary period; and (y) the variation of the terms of the Securities or the Indenture, if necessary, to give effect to the exercise of
any UK Bail-in Power by the Relevant UK Resolution Authority; and 
 (ii) consents to
the exercise of any UK Bail-in Power as it may be imposed without any prior notice by the Relevant UK Resolution Authority of its decision to exercise such power with respect to the Securities. 

(b) By its acquisition of the Securities, each Holder (which, for these purposes, includes each Beneficial Owner): 

(i) acknowledges and agrees that neither a Capital Adequacy Trigger Event, an Automatic Conversion, a reduction or
cancellation, in part or in full, of the Amounts Due (including pursuant to Sections 2.03 and 2.04), the conversion thereof into another security or obligation of the Company or another Person, as a result of the exercise of the UK Bail-in Power by the Relevant UK Resolution Authority with respect to the Securities, nor the exercise of the UK Bail-in Power by the Relevant UK Resolution Authority with
respect to the Securities shall give rise to a Default or an 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; 

(ii) 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 the UK Bail-in Power by the Relevant UK Resolution Authority with respect to the Securities; 

(iii) acknowledges and agrees that, upon the exercise of any UK Bail-in Power by the
Relevant UK Resolution Authority (a) the Trustee shall not be required to take any further directions from Holders under Section 5.12 of the Base Indenture and (b) none of the Base Indenture or this Sixth Supplemental Indenture shall
impose any duties upon the Trustee whatsoever with respect to the exercise of any UK Bail-in Power by the Relevant UK Resolution Authority; and 

(iv) shall be deemed to have authorized, directed and requested DTC and any direct participant in DTC or other intermediary
through which it holds such Securities to take any and all necessary action, if required, to implement the exercise of the UK 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, the Trustee or the Paying Agent. 
 (c) Upon the exercise of the UK Bail-in Power by the Relevant UK Resolution Authority with respect to the Securities, the Company shall provide a written notice to Holders through DTC as soon as practicable regarding such exercise of the UK Bail-in Power. The Company shall also deliver a copy of such notice to the Trustee for information purposes. 

(d) The exercise of the UK Bail-in Power by the Relevant UK Resolution Authority with respect to the
Securities shall not constitute a Winding-Up Event or a Non-Payment Event. 

  
 29 

 (e) In addition to the right to enter into supplemental indentures pursuant to Sections 9.01 and
9.02 of the Base Indenture, the Company 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 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. 

(f) Notwithstanding anything to the contrary in the Indenture, including Article 9 of the Base Indenture, the Company hereby agrees that it
shall not amend Section 2.20(a) without the prior consent of the Relevant Regulator. 
 (g) Notwithstanding Section 2.20(b)(iii),
if, following the completion of the exercise of the UK Bail-in Power by the Relevant UK Resolution Authority, any 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 Securities), then the Trustee’s duties under the Indenture shall remain applicable with respect to the Securities following such
completion to the extent the Company 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 in the event the Securities remain Outstanding following the completion of the exercise of the UK Bail-in Power. 

(h) For the avoidance of doubt, the potential conversion of the Securities into shares, other securities or other obligations in connection
with the exercise of any UK Bail-in Power by the Relevant UK Resolution Authority is separate and distinct from an Automatic Conversion following a Capital Adequacy Trigger Event. 

SECTION 2.21. Notice via DTC. If notice is given by the Company via DTC in accordance with the terms of the Securities and
the Indenture, the Company shall request that DTC, pursuant to the applicable rules and operating procedures of DTC then in effect, transmit such notice to the direct participants of DTC holding the Securities at such time. Moreover, any notice by
DTC to participating institutions and by these participants to street name holders of beneficial interests in the Securities shall be made according to arrangements among them and may be subject to statutory or regulatory requirements. Any such
notice given by the Company to DTC also shall be sent directly to the Trustee and the Paying Agent for informational purposes. 

SECTION 2.22. Records Adjustment. Upon receipt of any notice given pursuant to the Indenture, to the extent applicable, the
Company, the Trustee and the Agent shall adjust their records to reflect any cancellation or deemed cancellation of any interest and any changes to the aggregate principal amount of the Securities then Outstanding, including due to any exercise of
the UK Bail-in Power by the Relevant UK Resolution Authority, any Automatic Conversion or any redemption pursuant to Sections 2.08, 2.09 and 2.10. 

ARTICLE III 

ANTI-DILUTION 

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

  
 30 

 (a) If and whenever there is a consolidation, reclassification, redesignation or subdivision in
relation to the Ordinary Shares which alters the number of Ordinary Shares in issue, each Price shall be adjusted by multiplying the relevant Price in effect immediately prior to such consolidation, reclassification or subdivision by the following
fraction: 
 A 
 B 

where: 
  

	 	A	is the aggregate number of Ordinary Shares in issue immediately before such consolidation, reclassification, redesignation or subdivision, as the case may be; and 

 

	 	B	is the aggregate number of Ordinary Shares in issue immediately after, and as a result of, such consolidation, reclassification, redesignation or subdivision, as the case may be. 

Such adjustment shall become effective on the date the consolidation, reclassification, redesignation or subdivision, as the case may be, takes
effect. 
 (b) If and whenever the Company issues Ordinary Shares to Shareholders credited as fully paid 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 Shareholders would or could otherwise
have elected to receive, (2) where Shareholders may elect to receive a Cash Dividend in lieu of such Ordinary Shares or (3) where any such Ordinary Shares are or are expected 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 Shareholders, whether at their election or otherwise), each Price shall be adjusted by multiplying the relevant Price in effect immediately prior to such issue by the
following fraction: 
 A 

B 
 where: 

A is the aggregate number of Ordinary Shares in issue immediately before such issue; and 

B is the aggregate number of Ordinary Shares in issue immediately after such issue. 

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

(c) If and whenever the Company issues Ordinary Shares to Shareholders as a class by way of rights, or the Company or any member of the HSBC
Group or (at the direction or request or pursuant to arrangements with the Company or any member of the HSBC Group) any other company, person or entity issues or grants to Shareholders as a class by way of rights, any options, warrants or other
rights to subscribe for or purchase the Ordinary Shares, or any securities which by their terms of issue carry (directly or indirectly) rights of conversion into, or exchange or subscription for, any Ordinary Shares (or grants any such rights in
respect of existing securities so issued), in each case at a price per Ordinary Share which is less than 95% of the Current Market Price on the Effective Date, each Price shall be adjusted by multiplying the relevant Price in effect immediately
prior to the Effective Date by the following fraction: 
 A + B 

A + C 

  
 31 

 where: 
  

	 	A	is the aggregate number of Ordinary Shares in issue on the Effective Date; 

  

	 	B	is the number of Ordinary Shares which the aggregate consideration (if any) receivable for the Ordinary Shares issued by way of rights, or for the securities issued by way of rights, or for the options or warrants or
other rights issued by way of rights and for the total number of the Ordinary Shares deliverable on the exercise thereof, would purchase at such Current Market Price on the Effective Date; and 

 

	 	C	is the number of Ordinary Shares to be issued or, as the case may be, the maximum number of Ordinary Shares which may be issued upon exercise of such options, warrants or rights calculated as of the date of issue of
such options, warrants or rights or upon conversion or exchange or exercise of rights of subscription or purchase in respect thereof at the initial conversion, exchange, subscription or purchase price or rate; provided that if, on the
Effective Date, such number of Ordinary Shares is to be determined by reference to the application of a formula or other variable feature or the occurrence of any event at some subsequent time, then “C” shall be determined by the
application of such formula or variable feature or as if the relevant event occurs or had occurred as of the Effective Date and as if such conversion, exchange, subscription, purchase or acquisition had taken place on the Effective Date.

 Such adjustment shall become effective on the Effective Date. 

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

	 	(1)	the aggregate consideration receivable or price for Ordinary Shares issued for cash shall be the amount of such cash; 

  

	 	(2)	(x) the aggregate consideration receivable or price for Ordinary Shares to be issued or otherwise made available upon the conversion or exchange of any securities shall be deemed to be the consideration or price
received or receivable for any such securities and (y) the aggregate consideration receivable or price for Ordinary Shares to be issued or otherwise made available upon the exercise of rights of subscription attached to any securities or upon
the exercise of any options, warrants or rights shall be deemed to be that part (which may be the whole) of the consideration or price received or receivable for such securities or, as the case may be, for such options, warrants or rights which are
attributed by the Company to such rights of subscription or, as the case may be, such options, warrants or rights or, if no part of such consideration or price is so attributed, the Fair Market Value of such rights of subscription or, as the case
may be, such options, warrants or rights as of the relevant Effective Date, plus in the case of each of (x) and (y), the additional minimum consideration receivable or price (if any) upon the conversion or exchange of such securities, or upon
the exercise of such rights or subscription attached thereto or, as the case may be, upon exercise of such options, warrants or rights and (z) the consideration receivable or price per Ordinary Share upon the conversion or exchange of, or upon
the exercise of such rights of subscription attached to, such securities or, as the case may be, upon the exercise of such options, warrants or rights shall be the aggregate consideration or price referred to in (x) or (y) (as the case may be)
divided by the number of Ordinary Shares to be issued upon such conversion or exchange or exercise at the initial conversion, exchange or subscription price or rate; 

  
 32 

	 	(3)	if the consideration or price determined pursuant to (1) or (2) (or any component thereof) is expressed in a currency other than dollars, it shall be converted into dollars at the Prevailing Rate on the relevant
Effective Date (in the case of (1) above) or the relevant date of first public announcement (in the case of (2) above); 

  

	 	(4)	in determining the consideration or price pursuant to the above, no deduction shall be made for any commissions or fees (howsoever described) or any expenses paid or incurred for any underwriting, placing or management
of the issue of the relevant Ordinary Shares or securities or options, warrants or rights, or otherwise in connection therewith; and 

  

	 	(5)	the consideration or price shall be determined as provided above on the basis of the consideration or price received, receivable, paid or payable, regardless of whether all or part thereof is received, receivable, paid
or payable by or to the Company or another entity. 

 (d) If and whenever the Company pays any Extraordinary Dividend to the
Ordinary Shareholders as a class, each Price shall be adjusted by multiplying the relevant Price in effect immediately prior to the Effective Date by the following fraction: 

A – B 

   A 
 where: 

 

	 	A	is the Current Market Price of one Ordinary Share on the Effective Date; and 

  

	 	B	is the portion of the aggregate Extraordinary Dividend attributable to one Ordinary Share, with such portion being determined by dividing the aggregate Extraordinary Dividend by the number of Ordinary Shares entitled to
receive the relevant Extraordinary Dividend. If the Extraordinary Dividend is expressed in a currency other than dollars, it shall be converted into dollars at the Prevailing Rate on the relevant Effective Date. 

Such adjustment shall become effective on the Effective Date. 

(e) Notwithstanding provisions of Sections 3.01(a) through (d): 

(i) where the events or circumstances giving rise to any adjustment pursuant to this Section 3.01 have already
resulted or shall result in an adjustment to the Prices 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 shall give rise to an adjustment to the Prices
or where more than one event that gives rise to an adjustment to the Prices occurs within such a short period of time that, in the Company’s opinion, 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 by an Independent Financial Adviser to be in its opinion appropriate to give the intended result; 

  
 33 

 (ii) such modification shall be made to the operation of this Section 3.01
as may be determined by an Independent Financial Adviser to be in its opinion appropriate (x) to ensure that an adjustment to the Prices or the economic effect thereof shall not be taken into account more than once, (y) to ensure that the
economic effect of an Extraordinary Dividend is not taken into account more than once and (z) to reflect a redenomination of the issued Ordinary Shares for the time being into a new currency; 

(iii) for the avoidance of doubt, the occurrence of any other event in respect of the Ordinary Shares that is not an applicable
Adjustment Event in relation to the Securities or the conversion of the Securities into the Ordinary Shares pursuant to this Section 3.01 shall not result in an adjustment of the Prices; and 

(iv) No adjustment shall be made to the Prices where the Ordinary Shares or other securities (including rights, warrants and
options) are issued, offered, exercised, allotted, purchased, appropriated, modified or granted to, or for the benefit of, employees or former employees (including directors holding or formerly holding executive office or the personal service
company of any such person) or their spouses or relatives, in each case, of the Company or any company in the HSBC Group or any associated company or to a trustee or trustees to be held for the benefit of any such person, in any such case pursuant
to any share or option scheme. 
 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 sub-division as described in Section 3.01(a), 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 3.01(b) through (d), but before the relevant adjustment to the Prices becomes effective under
such Section. 
 SECTION 3.03. Decision of an Independent Financial Adviser. If any doubt shall arise as to whether an
adjustment should be made to either Price or as to the appropriate adjustment to such Prices, 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, the Paying Agent 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 and the Conversion Shares Offer Price. 

(a) On any adjustment, if a resultant Price has more decimal places than the initial Price, it shall be rounded to the same number of decimal
places as the initial Price. No adjustment shall be made to a Price where such adjustment (rounded down if applicable) would be less than 1% of such Price then in effect. Any adjustment not required to be made, and/or any amount by which a 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 Prices shall be given by the Company
to Holders via DTC (or, if the Securities are definitive Securities, via the Trustee) promptly after the determination thereof. 
 (c) The
Prices shall not in any event be reduced to below the nominal value of the Ordinary Shares. The Company hereby undertakes that it shall not take any action, and shall procure that no action is taken, that would otherwise result in an adjustment to
the Prices to below such nominal value. 

  
 34 

 SECTION 3.05. Qualifying Takeover Event. 

(a) Within ten (10) Business Days following the occurrence of a Takeover Event, the Company shall deliver a Takeover Event Notice. 

(b) If the Takeover Event is a Qualifying Takeover Event, the Securities will, where the Conversion Date falls on or after the QTE Effective
Date, be converted into or exchanged for Approved Entity Shares, mutatis mutandis as provided under Section 2.15, at a Conversion Price that shall initially be the New Conversion Price, which may be higher or lower than the Conversion
Price. In addition, the Company shall retain the right to elect in the Conversion Shares Offer Notice that the Conversion Shares Depository make a Conversion Shares Offer at the New Conversion Shares Offer Price. 

(c) The New Conversion Price and the New Conversion Shares Offer Price shall be subject to adjustment in the circumstances provided for under
Section 3.01 (if necessary with such modifications and amendments as an Independent Financial Adviser shall determine to be appropriate), and the Company shall give notice to the Holders of the New Conversion Price and the New Conversion Shares
Offer Price and of any such modifications and amendments thereafter. 
 (d) In the case of a Qualifying Takeover Event 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 and conditions 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 2.15, at the New Conversion Price. 
 (e) For the avoidance of doubt, if for
any reason (including, without limitation, because the Acquirer is a Governmental Entity), a Takeover Event fails to be Qualifying Takeover Event, there shall not be 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. From and after the QTE Effective Date, the Company shall no longer have any obligation to deliver Ordinary Shares or any Approved Entity Shares, which shall
be the obligation of the Approved Entity pursuant to the terms of the agreements or arrangements with the Trustee. 
 ARTICLE IV 

DEFAULTS AND REMEDIES 

With respect to the Securities only, Section 5.01 of the Base Indenture shall be amended and restated in its entirety as follows in
Section 4.01 hereof, Section 5.02 of the Base Indenture shall be amended and restated in its entirety as follows in Sections 4.02 and 4.03 hereof, Section 5.03(a) of the Base Indenture shall be amended and restated in its
entirety as follows in Section 4.04 hereof, Section 5.13 of the Base Indenture shall be amended and restated in its entirety as follows in Section 4.05 hereof, and references in the Base Indenture to such Sections shall be to
such Sections as amended and restated in entirety by this Sixth Supplemental Indenture. Section 5.10 of the Base Indenture shall apply to the Securities subject to the limitations on remedies specified in this Article IV. 

  
 35 

 SECTION 4.01. Winding-Up. 

(a) 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 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. 
 (b) If a Winding-Up Event occurs before the occurrence of a Capital Adequacy Trigger
Event, the principal amount of the Securities 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. 

SECTION 4.02. Non-Payment Event. If the Company fails to pay any amount that has
become due and payable under the Securities, the Paying Agent shall notify the Trustee and, if such failure continues for fourteen (14) calendar days, the Trustee may provide a written notice of such failure to the Company. If within a period
of fourteen (14) calendar 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
in accordance with the Indenture, 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 Section 2.03 or 2.04, the Company cancels any interest payment in respect of any Interest Payment Date or if such interest payment is deemed to have been 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 shall occur or be deemed to have occurred as a result of such cancellation or deemed
cancellation (in each case, in whole or in part). 
 SECTION 4.03. Limited Remedies for Breach of Obligations (Other than Non-Payment). In addition to the remedies for a Non-Payment Event provided in Section 4.02, the Trustee may without further notice institute such proceedings against
the Company as it 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 payment of any principal or interest, including Additional Amounts) (such obligation, a “Performance Obligation”); provided the sole and exclusive remedy that the Trustee (acting on behalf of the
Holders) and/or the Holders may seek under the Securities and the Indenture is specific performance under the laws of the State of New York; provided further that to the extent any judgment or other award given in such proceedings
requires the payment of money by the Company, whether by way of damages or otherwise (a “Monetary Judgment”), the Trustee (acting on behalf of the Holders) and/or the Holders may not enforce, and shall not be entitled to enforce, or
otherwise claim such Monetary Judgment against the Company, except by proving such Monetary Judgment in the winding-up or administration of the Company. For the avoidance of doubt, any breach by the Company of
any Performance Obligation shall not confer upon the Trustee (acting on behalf of the Holders) and/or the Holders any claim other than specific performance and the Company shall not be obliged to pay any sum or sums, in cash or otherwise (including
damages), as a consequence of the institution of any such proceedings, except where a Holder proves any Monetary Judgment in the Company’s winding-up or administration. 

By its acquisition of the Securities, each Holder (which, for these purposes includes each Beneficial Owner) of the Securities acknowledges
and agrees (i) that the sole and exclusive remedy that such Holder and/or the Trustee (acting on their behalf) may seek under the Securities and the Indenture for a breach by the Company of a Performance Obligation is specific performance under
the laws of the State of New York, (ii) such Holder shall not (and waive any right to) seek, and shall not (and waive any right to) direct the Trustee (acting on their behalf) to seek, any other remedy against the Company in

  
 36 

 
respect of any breach by the Company of a Performance Obligation, (iii) such Holder shall not (and waive any right to) enforce, and shall not be entitled to enforce (and waive any such
entitlement), or otherwise claim (and waive any other right to claim) a Monetary Judgment against the Company, except by proving such Monetary Judgment in the Company’s winding-up or administration and
(iv) to the extent permitted by the Trust Indenture Act, such Holder waives any and all claims, in law and/or in equity, against the Trustee for, agree not to initiate a suit against the Trustee in respect of, and agree that the Trustee shall
not be liable for, any action that the Trustee takes, or abstains from taking, in connection with such Holder’s right to enforce a Performance Obligation in accordance with the Indenture or the Securities. 

SECTION 4.04. No Other Remedies and Other Terms. 

(a) Other than the limited remedies specified in this Article IV, and subject to clause (c) below, no remedy against the Company
shall be available to the Trustee (acting on behalf of the Holders) and to the Holders and Beneficial Owners, whether for the recovery of amounts owing in respect of such 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 5.06 of the Base Indenture expressly survive any Default and are not subject to the
subordination provisions of Section 5.01 hereof. 
 (b) In the case of a Default under the Securities, 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 (i) upon the occurrence of a Winding-Up Event that occurs before the Conversion Date or (ii) upon the occurrence of a
Non-Payment Event or (iii) upon a breach by the Company of a Performance Obligation. For purposes of the Base Indenture, “Event of Default” shall mean “Default” as defined in this
Sixth Supplemental Indenture, except that the term “Event of Default” as used in Section 3.05(c)(ii) of the Base Indenture and Article 8 of the Base Indenture shall mean
“Winding-Up Event.” 
 (c) Subject to such provisions for the indemnification of the
Trustee, and subject to certain exceptions, the Holder or Holders of a majority in aggregate principal amount of the Securities then Outstanding shall have the right to direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee or exercising any trust or power conferred on the Trustee with respect to the Securities. However, the Trustee may refuse to follow any direction that is in conflict with any rule of law or the Indenture or is unjustly
prejudicial to any Holder not taking part in the direction. The Trustee may take any other action that it deems proper which is not inconsistent with that direction. 

(d) Neither a Capital Adequacy Trigger Event, an Automatic Conversion, a cancellation or deemed cancellation of interest (in each case, in
whole or in part) in accordance with the terms of the Indenture and the Securities nor the exercise of the UK Bail-in Power by the Relevant UK Resolution Authority with respect to the Securities shall be
stated to be an Event of Default or a Default. 
 (e) Notwithstanding the limitations on remedies specified under this Article IV,
(i) 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 under the provisions of the Indenture, and (ii) nothing shall impair
the right of a Holder or Beneficial Owner 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
(i) and (ii) 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 5.01 hereof. 

  
 37 

 SECTION 4.05. Waiver of Past Defaults. 

(a) Holders of not less than a majority in aggregate principal amount of the Securities then Outstanding may on behalf of the Holders of all of
the Securities waive any past Default that results from a breach by the Company of a Performance Obligation; provided that (i) a Default in respect of a Performance Obligation, the modification or amendment of which would require the
consent of each Holder affected by it or (ii) any past Default that results from a Winding-Up Event or a Non-Payment Event, in either case, will require the waiver
of each Holder affected by such Default. 
 (b) Upon the occurrence of any waiver permitted by clause (a) above, such Default shall
cease to exist, and any Default with respect to any series arising therefrom shall be deemed to have been cured and not to have occurred for every purpose of the Base Indenture, but no such waiver shall extend to any subsequent or other Default or
impair any right consequent thereon. 
 ARTICLE V 

SUBORDINATION 

SECTION 5.01. Securities Subordinate to Claims of Senior Creditors. With respect to the Securities only, this Section 5.01
hereby amends Section 12.01 of the Base Indenture in its entirety, and references in the Base Indenture to Article Twelve and Section 12.01 thereof shall be to such Article and Section as amended by this Section 5.01.

 (a) The Securities shall constitute the Company’s direct, unsecured and subordinated obligations, ranking equally without any
preference among themselves. The rights and claims of the Holders and Beneficial Owners in respect of or arising from the Securities shall be subordinated to the claims of Senior Creditors. 

(b) If (x) 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 of the Company, the terms of which reorganization, reconstruction or amalgamation
(i) have previously been approved in writing by a majority of the Holders and (ii) do not provide that the Securities shall thereby become redeemable or repayable in accordance with the terms of the Securities); or (y) following the
appointment of an administrator for the Company’s administration, the administrator declares, or gives notice that it intends to declare and distribute, a dividend, then 

(i) if such events specified in (x) or (y) 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 if, on the day prior to the commencement of such winding-up or such administration and thereafter, such Holder were the holder of the most senior class of preference shares in the Company’s capital, having an equal right to a return of assets in such 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
of assets in such 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 Company’s capital, but ranking junior to the claims
of Senior Creditors, and on the assumption that the amount that such Holder was entitled to receive in respect of such senior preference shares, on a return of assets in such winding-up or such administration,
were an amount equal to the principal amount of the relevant Security, together with any accrued but unpaid interest thereon (to the extent not cancelled or deemed to have been cancelled) and any Monetary Judgment (if payable); and 

  
 38 

 (ii) if such events specified in (x) or (y) above occur on or after the
date on which a Capital Adequacy Trigger Event occurs but prior to the Conversion Date, 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 on a return of assets in such winding-up or such administration if the Conversion Date in respect of an Automatic Conversion had occurred immediately prior to the occurrence of such events
specified in (x) or (y) above (and as a result, such Holder were the holder of such number of Ordinary Shares as such Holder would have been entitled to receive on the Conversion Date, ignoring for these purposes the Company’s right
to elect to make a Conversion Shares Offer). 
 (c) Other than in the event of a winding-up or
administration of the Company as described in clause (b) above, 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, 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 (i) it is able to pay its debts owed to Senior Creditors as they fall due
and (ii) the Balance Sheet Condition has been met. A certificate by the Auditors as to whether or not the Solvency Condition is met, on the basis of the information provided to the Auditors by the Company, will, in the absence of manifest
error, 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 (i) who are unsubordinated creditors; (ii) whose claims are, or
are expressed to be, subordinated to the claims of the Company’s unsubordinated creditors but not further or otherwise; or (iii) whose claims are, or are expressed to be, junior to the claims of the Company’s other creditors, 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 or Beneficial Owners in a winding-up occurring
prior to a Capital Adequacy Trigger Event. For the avoidance of doubt, holders of any of the Company’s existing or future Tier 2 capital instruments shall be Senior Creditors. 

The “Balance Sheet Condition” shall be satisfied in relation to the Company if the value of the Assets is at least equal to
the value of the Liabilities. For these purposes (i) “Assets” mean the Company’s unconsolidated gross assets as shown in the Company’s most recent published audited balance sheet, as adjusted for subsequent events in such
manner as the Auditors may determine and (ii) “Liabilities” means the Company’s unconsolidated gross liabilities, as shown in the Company’s most recent published audited balance sheet, as adjusted for subsequent events in
such manner as the Auditors may determine and for these purposes excluding (without double counting) any indebtedness that shall not constitute 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 UK 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.

 ARTICLE VI 

AMENDMENTS TO THE BASE INDENTURE APPLICABLE TO ALL SERIES OF SECURITIES 

SECTION 6.01. Definitions. Article 1 of the Base Indenture is amended by amending and restating the definition of
“FATCA” in Section 1.01 in its entirety, which shall read as follows: 
 “FATCA” means
(i) sections 1471 to 1474 of the Code or any associated regulations or other official guidance; (ii) any treaty, law, regulation or other official guidance enacted in any other jurisdiction, or relating to an intergovernmental agreement
between the United States and any other jurisdiction, which (in either case) facilitates the implementation of clause (i); or (iii) any agreement pursuant to the implementation of clauses (i) or (ii) with the US Internal Revenue Service,
the US government or any governmental or taxation authority in any other jurisdiction. 
 SECTION 6.02. Additional
Amounts. Article 10 of the Base Indenture is amended by amending and restating Section 10.04(a) of the Base Indenture in its entirety, which shall read as follows: 

(a) All payments made under or with respect to the Securities shall be paid without deduction or withholding for, or on account
of, any and all present and future taxes, levies, imposts, duties, charges, fees, deductions or withholdings whatsoever imposed, levied, collected, withheld or assessed by or on behalf of the UK (or any political subdivision or taxing authority
thereof or therein having the power to tax) (each a “Taxing Jurisdiction”) unless required by law. If such deduction or withholding will at any time be required by the law of the Taxing Jurisdiction, the Company shall pay such
additional amounts in respect of any payments of interest on the Securities (but not, for the avoidance of doubt, in respect of the payment of principal in respect of the Securities) (“Additional Amounts”) as may be necessary so
that the net amounts (including Additional Amounts) paid to the Holders, after such deduction or withholding, shall be equal to the respective amounts of interest which the Holders would have been entitled to receive in respect of the Securities in
the absence of such deduction or withholding; provided that the foregoing will not apply to any such tax, levy, impost, duty, charge, fee, deduction or withholding which: (i) would not be payable or due but for the fact that the Holder
or Beneficial Owner is domiciled in, or is a national or resident of, or engaging in business or maintaining a permanent establishment or being physically present in, the Taxing Jurisdiction, or otherwise has some connection or former connection
with the Taxing Jurisdiction other than the holding or ownership of a Security, or the collection of principal or interest payments on, or the enforcement of, a Security; (ii) would not be payable or due but for the fact that the certificate
representing the relevant Securities (x) is presented for payment in the Taxing Jurisdiction or (y) is 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 would have been entitled to such Additional Amount on presenting the same for payment at the close of such thirty (30) day period; (iii) would not have been imposed if presentation for payment of the
certificate representing the relevant Securities had been made to a paying agent other than the paying agent to which the presentation was made; (iv) is imposed in respect of a Holder that is not the sole Beneficial Owner of the principal or
the interest, or a portion of either, or that is a fiduciary or partnership, but only to the extent that a beneficiary or settlor with respect to the fiduciary, a beneficial owner or member of the partnership would not have been entitled to the
payment of an Additional Amount had the beneficiary, settlor, beneficial owner or member received directly its beneficial or distributive share of the payment; (v) is imposed because of the failure to comply by the Holder or the Beneficial
Owner or the Beneficial Owner of any payment on such Securities with a request from the Company addressed to the Holder or the Beneficial 

  
 40 

 
Owner, including a written request from the Company related to a claim for relief under any applicable double tax treaty (x) to provide information concerning the nationality, residence,
identity or connection with a taxing jurisdiction of the Holder or the Beneficial Owner or (y) to make any declaration or other similar claim to satisfy any information or reporting requirement, if the information or declaration is required or
imposed by a statute, treaty, regulation, ruling or administrative practice of the Taxing Jurisdiction as a precondition to exemption from withholding or deduction of all or part of the tax, duty, assessment or other governmental charge;
(vi) is imposed in respect of any estate, inheritance, gift, sale, transfer, personal property, wealth or similar tax, duty assessment or other governmental charge; or (vii) is imposed in respect of any combination of the above items. 

Whenever in this Indenture there is mentioned, in any context, the payment of any interest, if any, on or in respect of any
Security, such mention shall be deemed to include mention of the payment of Additional Amounts provided for in this Section to the extent that, in such 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. 

ARTICLE VII

 GLOBAL SECURITY 

HSBC Holdings plc 
 $[•] 

6.250% Perpetual Subordinated Contingent Convertible Securities 

(Callable March 23, 2023 and Every Five Years Thereafter) 

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 under and governed by the Indenture, dated as of August 1, 2014 (the “Base Indenture”), as supplemented by the Sixth Supplemental
Indenture, dated as of March 23, 2018 (the “Sixth Supplemental Indenture” and, together with the Base Indenture, the “Indenture”). 

HSBC Holdings 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 to Cede & Co., or registered assigns, the principal sum of $[•] ([•]), 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 and
shall not be redeemable except as provided in this Security and Sections 2.08, 2.09 and 2.10 of the Sixth Supplemental Indenture. 
 From
(and including) the Issue Date to (but excluding) March 23, 2023, the interest rate on the Securities shall be 6.250% per annum. From (and including) each Reset Date to (but excluding) the next following Reset Date, the applicable per annum
interest rate shall be equal to the sum of the applicable Mid-Market Swap Rate on the Reset Determination Date and 3.453%. Subject to the provisions on the reverse of this Security relating to cancellation and
deemed cancellation of interest and to Sections 2.03 and 2.04 of the Sixth Supplemental Indenture, interest, if any, shall be payable in two equal semi-annual installments in arrear on March 23 and September 23 of each year (each, an
“Interest Payment Date”); provided that if such 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. Subject to the provisions on the reverse of this Security relating to cancellation and deemed cancellation of interest and to Sections 2.03 and 2.04 of the Sixth Supplemental Indenture, interest on the Securities,
if any, shall be computed and payable in arrear and on the basis of a year of 360 days consisting of twelve (12) months of thirty (30) days each and, in the case of an incomplete month, the actual number of days elapsed. The first date on
which interest may be paid shall be September 23, 2018, for the period commencing on (and including) the Issue Date and ending on (but excluding) September 23, 2018. If a date of redemption is not a Business Day, the Company may pay
interest (if any) together with the principal on the next succeeding Business Day; provided that interest shall not accrue during the period from and after the date of redemption. 

The “Mid-Market Swap Rate” is the Mid-Market
Swap Rate Quotation that appears on Bloomberg page “ISDA 01” (or such other page as may replace such page on Bloomberg or such other information service, in each case, as may be nominated by the person providing or sponsoring the
information appearing on such page for purposes of displaying comparable rates) (the “Relevant Screen Page”) as of approximately 11.00 a.m. (New York time) on the relevant Reset Determination Date, all as determined by the
Calculation Agent; provided, however, that if no such rate appears on the Relevant Screen Page for a five-year term, then the Mid-Market Swap Rate shall be determined through the use of
straight-line interpolation by reference to two rates, one of which shall be determined in accordance with the above provisions, but as if the relevant Reset Period were the period of time for which rates are available next shorter than the length
of the actual Reset Period and the other of which shall be determined in accordance with the above provisions, but as if the relevant Reset Period were the period 

  
 A-2 

 
of time for which rates are available next longer than the length of the actual Reset Period; provided further that if on any Reset Determination Date the Relevant Screen Page is
not available or the Mid-Market Swap Rate does not appear on the Relevant Screen Page, the Calculation Agent shall request the principal office in New York of the Reference Banks to provide it with its Mid-Market Swap Rate Quotation as of approximately 11.00 a.m. (New York time) on the relevant Reset Determination Date. If two or more of the Reference Banks provide the Calculation Agent with Mid-Market Swap Rate Quotations, the interest rate for the relevant Reset Period shall be the sum of 3.453% and the arithmetic mean (rounded, if necessary, to the nearest 0.001% (0.0005% being rounded upwards)) of
the relevant Mid-Market Swap Rate Quotations, as determined by the Calculation Agent. If only one or none of the Reference Banks provides the Calculation Agent with a
Mid-Market Swap Rate Quotation, the interest shall be determined to be the rate of interest as of the last preceding Reset Date or, in the case of the initial Reset Determination Date, 6.250%. 

“Mid-Market Swap Rate Quotation” means a quotation (expressed as a percentage rate
per annum) for the mean of the bid and offered rates for the fixed leg payable semi-annually (calculated on the basis of twelve 30-day months or, in the case of an incomplete month, the actual number of days
elapsed, in each case assuming a 360-day year) of a fixed-for-floating interest rate swap transaction in dollars which
transaction (i) has a five-year term commencing on the relevant Reset Date, (ii) is in an amount that is representative for a single transaction in the dollar swap rate market at 11.00 a.m. (New York time) with an acknowledged dealer of
good credit in the swap market and (iii) has a floating leg based on six-month LIBOR (calculated on the basis of twelve 30-day months or, in the case of an
incomplete month, the actual number of days elapsed, in each case assuming a 360-day year); provided that if (a) the Company determines that LIBOR has ceased to be calculated or administered and
(b) the Independent Financial Adviser, or, if the Company is unable to appoint the Independent Financial Adviser, the Company (acting in good faith and a commercially reasonable manner), determines that another rate has replaced LIBOR in
customary market usage for setting rates comparable to the Mid-Market Swap Rate (the “Alternative Base Rate”), then the Mid-Market Swap Rate Quotation
shall be the quotation of the mean of bid and offered rates determined as provided above but as if the reference to LIBOR was a reference to the Alternative Base Rate and with such adjustments (if any) as may in the Company’s determination
(after consultation with the Independent Financial Adviser, if appointed as provided above) be necessary to take account of any adjustment factor to make such rates comparable to rates quoted on the basis of LIBOR; provided further
that if the determination of the Alternative Base Rate occurs less than five (5) Business Days prior to the relevant Reset Determination Date, the rate of interest shall be as of the last preceding Reset Date or, in the case of the initial
Reset Determination Date, 6.250%. 
 “Reset Date” means March 23, 2023 and each fifth (5th) anniversary date thereafter. If any Reset Date is not a Business Day, the Reset Date shall occur on the next succeeding Business Day. For the avoidance of doubt, if the Reset Date is not a Business
Day and accordingly the Reset Date occurs on the next Business Day (the “Adjusted Reset Date”), then the equal semi-annual payment of interest (if paid) on the next Interest Payment Date shall reflect interest for the entire
interest period (including any portion of such interest period occurring between the originally scheduled Reset Date and the Adjusted Reset Date) at the interest rate determined based on the Adjusted Reset Date, and not at the interest rate that
applied to the immediately preceding semi-annual interest period. In addition and for the avoidance of doubt, in connection with any optional redemption of this Security pursuant to the terms of this Security and Section 2.08 of the Sixth
Supplemental Indenture, if the Reset Date is not a Business Day, as described above, the Company may pay the interest (if any) together with the principal on the Adjusted Reset Date, but interest on that payment shall not accrue during the period
from and after the last Interest Payment Date. 

  
 A-3 

 By its acquisition of the Securities, each Holder (which, for these purposes includes each
Beneficial Owner) (i) waives any and all claims, in law and/or in equity, against the Trustee and the Agent for, agrees not to initiate a suit against the Trustee and the Agent in respect of, and agrees that neither the Trustee nor the Agent
shall be liable for, the determination of or the failure to determine any Alternative Base Rate (including any adjustments thereto) and any losses suffered in connection therewith, and (ii) agrees that neither the Trustee nor the Agent shall
have any obligation to determine any Alternative Base Rate (including any adjustments thereto), including in the event of any failure by the Company to determine any Alternative Base Rate. 

In addition to any other restrictions on payments of principal and interest contained in this Security and the Sixth Supplemental 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 UK Bail-in Power by the Relevant UK Resolution Authority
unless, at the time such repayment or payment, respectively, is scheduled to become due, 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 HSBC Group. 
 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. For the avoidance of doubt, 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 to
have been cancelled (in each case, in whole or in part) in accordance with the provisions of this Security and as set forth in Sections 2.03(a) and 2.04 of the Sixth Supplemental Indenture, and any interest cancelled or deemed to have been
cancelled (in each case, in whole or in part) pursuant to such Sections shall not be due and shall not accumulate or be payable at any time thereafter, and Holders and Beneficial Owners shall have no rights thereto or to receive any additional
interest or compensation as a result of such cancellation or deemed cancellation. 
 Without prejudice to the foregoing paragraph or the
provisions of Section 2.03 of the Sixth Supplemental Indenture or the prohibition contained in Article 141(2) of CRD (and any implementation of such provision in the United Kingdom or, as the case may be, any succeeding provision amending or
replacing such Article or any such implementing provision) on the making of payments on the Securities before the Maximum Distributable Amount has been calculated, and subject to the extent permitted by the immediately following sentence in respect
of partial interest payments in respect of this Security, the Company shall not make an interest payment in respect of this Security 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 (i) the amount of Relevant Distributions exceeds the amount of Distributable Items as of such Interest Payment Date; (ii) the aggregate of (x) the interest amount payable
in respect of the Securities and (y) the amounts of any distributions of the kind referred to in Article 141(2) of CRD (and any implementation of such provision in the United Kingdom or, as the case may be,

  
 A-4 

 
any succeeding provision amending or replacing such Article or any such implementing provision) exceeds the Maximum Distributable Amount (if any) applicable to the Company as of such Interest
Payment Date; (iii) the Solvency Condition is not satisfied in respect of such interest payment or the Relevant Regulator orders the Company to cancel (in whole or in part) the interest otherwise payable on such Interest Payment Date. 

The Company may, in its sole discretion, elect to make a partial interest payment in respect of this Security on any Interest Payment Date,
only to the extent that such partial interest payment may be made without breaching the restriction in the immediately preceding sentence. 

By its acquisition of the Securities, each Holder (which, for these purposes, includes each Beneficial Owner) acknowledges and agrees that
(a) 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 to have been cancelled (in whole or in part), including as a result of the Distributable Items or the Maximum Distributable Amount being exceeded, failing to satisfy the Solvency
Condition under Section 2.04 or an order from the Relevant Regulator; and (b) a cancellation or deemed cancellation of interest (in each case, in whole or in part) in accordance with the terms of the Indenture and this Security shall not
constitute a default in payment or otherwise under the terms of this Security or the Indenture. 
 Payments of principal of and interest, if
any, on this Security shall be made in dollars and such payments on this Security shall be made through one or more Paying Agents appointed under the Indenture to DTC or its nominee, as the Holder of this Security. Initially, the Paying Agent shall
be HSBC Bank USA, National Association. The Company may change the Paying Agent without prior notice to the Holders, and in such an event the Company may act as Paying Agent. Payments of principal of and interest on this Security 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. 

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 AND IS NOT INSURED BY THE UNITED
STATES FEDERAL DEPOSIT INSURANCE CORPORATION OR ANY OTHER GOVERNMENT AGENCY OF THE UNITED STATES OR THE UNITED KINGDOM.

 (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 under and governed by the Indenture, dated as of August 1, 2014 (herein called 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 HSBC Bank USA, National Association (“HBUS”), as Paying Agent and Registrar, as supplemented and amended
by the Sixth Supplemental Indenture, dated as of March 23, 2018 (the “Sixth Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), among the Company, the Trustee and HBUS, as Paying Agent,
Registrar and Calculation Agent, 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 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. 
 This Security is one of the series designated on the face hereof, limited to a principal amount of
$[•] 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. 
 All payments made under or with respect to this Security shall be paid without deduction or withholding for, or on account of,
any and all present and future taxes, levies, imposts, duties, charges, fees, deductions, or withholdings whatsoever imposed, levied, collected, withheld or assessed by or on behalf of the United Kingdom (or any political subdivision or taxing
authority thereof or therein having the power to tax) (each a “Taxing Jurisdiction”) unless required by law. If such deduction or withholding will at any time be required by the law of the Taxing Jurisdiction, the Company shall pay
such additional amounts in respect of any payments of interest on the Securities (but not, for the avoidance of doubt, in respect of the payment of principal in respect of the Securities) (“Additional Amounts”) as may be necessary
so that the net amounts (including Additional Amounts) paid to the Holders, after such deduction or withholding, shall be equal to the respective amounts of interest which the Holders would have been entitled to receive in respect of the Securities
in the absence of such deduction or withholding; provided that the foregoing will not apply to any such tax, levy, impost, duty, charge, fee, deduction or withholding which: (i) would not be payable or due but for the fact that the Holder or
Beneficial Owner is domiciled in, or is a national or resident of, or engaging in business or maintaining a permanent establishment or being physically present in, the Taxing Jurisdiction, or otherwise has some connection or former connection with
the Taxing Jurisdiction other than the holding or ownership of a Security, or the collection of principal or interest payments on, or the enforcement of, a Security; (ii) would not be payable or due but for the fact that the certificate
representing the relevant Securities (x) is presented for payment in the Taxing Jurisdiction or (y) is 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 would have been entitled to such Additional Amount on presenting the same for payment at the close of such thirty (30) day period; (iii) would not have been imposed if presentation for payment of the
certificate representing the relevant Securities had been made to a paying agent other than the paying agent to which the presentation was made; (iv) is imposed in respect of a Holder that is not the sole Beneficial Owner of the principal or
the interest, or a portion of either, or that is a fiduciary or partnership, but only to the extent that a beneficiary or settlor with respect to the fiduciary, a beneficial owner or member of the partnership would not have been entitled to the
payment of an Additional Amount had the beneficiary, settlor, beneficial owner or member received directly its beneficial or distributive share of the payment; (v) is imposed because of the failure to comply by the Holder or the Beneficial
Owner or the Beneficial Owner of any payment on such Securities with a request from the 

  
 A-7 

 
Company addressed to the Holder or the Beneficial Owner, including a written request from the Company related to a claim for relief under any applicable double tax treaty (x) to provide
information concerning the nationality, residence, identity or connection with a taxing jurisdiction of the Holder or the Beneficial Owner or (y) to make any declaration or other similar claim to satisfy any information or reporting
requirement, if the information or declaration is required or imposed by a statute, treaty, regulation, ruling or administrative practice of the Taxing Jurisdiction as a precondition to exemption from withholding or deduction of all or part of the
tax, duty, assessment or other governmental charge; (vi) is imposed in respect of any estate, inheritance, gift, sale, transfer, personal property, wealth or similar tax, duty assessment or other governmental charge; or (vii) is imposed in
respect of any combination of the above items. 
 Whenever in this Security or the Indenture there is mentioned, in any context, the payment
of any interest, if any, on or in respect of any Security, such mention shall be deemed to include mention of the payment of Additional Amounts provided for in this paragraph and in Section 10.04 of the Base Indenture, as amended by
Section 6.01 of the Sixth Supplemental Indenture, to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof pursuant to the provisions of this paragraph and in Section 10.04 of the Base
Indenture, as amended by Section 6.01 of the Sixth Supplemental Indenture, and as if express mention of the payment of Additional Amounts (if applicable) were made in any provisions hereof or thereof where such express mention is not made. 

Any amounts to be paid by the Company on this Security shall be paid net of any deduction or withholding imposed or required pursuant to
(i) sections 1471 to 1474 of the Code or any associated regulations or other official guidance; (ii) any treaty, law, regulation or other official guidance enacted in any other jurisdiction, or relating to an intergovernmental agreement
between the United States and any other jurisdiction, which (in either case) facilitates the implementation of clause (i); or (iii) any agreement pursuant to the implementation of clauses (i) or (ii) with the US Internal Revenue Service,
the US government or any governmental or taxation authority in any other jurisdiction (a “FATCA Withholding Tax”), and the Company shall not be required to 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 this Security 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 shall not apply to
payments made under this Security 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 under this paragraph and Section 10.04(d) of the Base Indenture shall be treated as paid to the Holder, and the Company shall not pay Additional Amounts in respect of such deduction or
withholding, except to the extent the provisions in this paragraph and Section 10.04 of the Base Indenture explicitly provide otherwise. 

Subject to the limitations specified below and in Sections 2.11 and 2.12 of the Sixth Supplemental Indenture, the Company may, at the
Company’s option in its sole discretion, redeem the Securities, in whole but not in part, on any 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 to have been cancelled as described on the face of this Security and in Sections 2.03 and 2.04 of the Sixth Supplemental Indenture) to (but excluding) the date fixed for redemption. 

  
 A-8 

 Subject to the limitations specified below and Section 2.12 of the Sixth Supplemental
Indenture, the Company may, at the Company’s option in its sole discretion, redeem this Security, in whole but not in part, at a redemption price equal to 100% of the principal amount of this Security then Outstanding, together with any accrued
but unpaid interest (which excludes any interest cancelled or deemed to have been cancelled as described on the face of this Security and in Sections 2.03 and 2.04 of the Sixth Supplemental Indenture) to (but excluding) the date fixed for
redemption, if, at any time, the Company determines that as a result of a change in, or amendment to, the laws of a Taxing Jurisdiction, including any treaty to which the relevant Taxing Jurisdiction is a party, or a change in an official
application or interpretation of those laws on or after the Issue Date, including a decision of any court or tribunal that becomes effective on or after the Issue Date: (i) on a subsequent date for the payment of interest on the Security the
Company would be required to pay any Additional Amounts; (ii) if the Company were to seek to redeem the Security on a subsequent date (for which purpose no consideration shall be given as to whether or not the Company would otherwise be
entitled to redeem the Security), the Company would be required to pay any Additional Amounts (notwithstanding the Company having made such endeavors as the Company considers reasonable); (iii) on a subsequent date for the payment of interest on the
Security, interest payments (or the Company’s funding costs as recognized in the Company’s accounts) under, or with respect to, the Security are no longer fully deductible for UK corporation tax purposes; (iv) the Security would no
longer be treated as loan relationships for UK tax purposes; (v) would, as a result of the Security being in issue, result in the Company not being able to have losses or deductions set against the profits or gains, or profits or gains offset
by the losses or deductions, of companies with which it is or would otherwise be so grouped for applicable UK tax purposes (whether under the group relief system current as of the Issue Date or any similar system or systems having like effect as may
from time to time exist); (vi) a future write-down of the principal amount of the Security or conversion of the Security into the Ordinary Shares would result in a UK tax liability, or the receipt of income or profit which would be subject to UK
tax, which would not otherwise have been the case as of the Issue Date; or (vii) the Security or any part thereof become treated as a derivative or an embedded derivative for UK tax purposes (each such change (or deemed change) in tax law or
regulation or the official application or interpretation thereof, a “Tax Event”). 
 Subject only to the Company’s
obligation to use such endeavors as provided in clause (ii) of the immediately preceding paragraph and Section 2.09(a)(ii) of the Sixth Supplemental Indenture, it shall be sufficient for the Company to deliver to the Trustee an
Officer’s Certificate stating that a Tax Event has occurred and is continuing and setting out the details thereof, as well as any opinion or certificate of an independent legal adviser on which such Officer’s Certificate is based. 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 shall be conclusive and binding
on the Holders and Beneficial Owners. 
 Subject to the limitations specified below and Section 2.12 of the Sixth Supplemental
Indenture, the Company may, at the Company’s option in its sole discretion, redeem this Security, in whole but not in part, at a redemption price equal to 100% of the principal amount of this Security then Outstanding, together with any accrued
but unpaid interest (which excludes any interest cancelled or deemed to have been cancelled as described on the face of this Security and in Sections 2.03 and 2.04 of the Sixth Supplemental Indenture) to (but excluding) the date fixed for
redemption, if the Company determines, at any time after the Issue Date, there is a change in the regulatory classification of the Securities that results or shall result in either their (i) exclusion in whole or in part from the HSBC
Group’s regulatory capital (other than as a consequence of an Automatic Conversion); or (ii) reclassification in whole or in part as a form of the HSBC Group’s regulatory capital that is lower than additional Tier 1 capital (a
“Capital Disqualification Event”). 

  
 A-9 

 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 pursuant to any of the four immediately preceding paragraphs. 

Before the Company may redeem this Security pursuant to any of the preceding paragraphs relating to the Company’s rights of redemption or
Sections 2.08, 2.09 and 2.10 of the Sixth Supplemental Indenture, the Company shall deliver via DTC prior notice of not less than thirty (30) days, nor more than sixty (60) days to the Holders provided, however, that in
the case of a Tax Event, no notice of redemption shall be given earlier than 90 days prior to the earliest date on which the Company would be obliged to pay Additional Amounts were a payment in respect of the Securities then due. Such notice shall
specify the Company’s election to redeem this Security and the date fixed for such redemption and shall be irrevocable except in the limited circumstances described in the remainder of this paragraph and clauses (b), (c) and (d) of
Section 2.11 of the Sixth Supplemental Indenture. If the Company has delivered a notice of redemption pursuant to this paragraph or Section 2.11 of the Sixth Supplemental Indenture, but as of the date specified for redemption in such
notice, the Solvency Condition is not satisfied in respect of the relevant redemption payment, 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. If the Company has delivered a notice of redemption pursuant to this paragraph or Section 2.11 of the Sixth Supplemental Indenture, but prior to the payment of the redemption amount with respect to such redemption a Capital
Adequacy Trigger Event occurs, such redemption notice shall be automatically rescinded and shall be of no force and effect, no payment in respect of the redemption amount shall be due and payable (and, for the avoidance of doubt, an Automatic
Conversion shall occur after such Capital Adequacy Trigger Event pursuant to the terms of this Security and Section 2.15(a) of the Sixth Supplemental Indenture). If the Company has delivered a notice of redemption pursuant to this paragraph or
Section 2.11 of the Sixth Supplemental Indenture, but prior to the payment of the redemption amount with respect to such redemption the Relevant UK Resolution Authority exercises its UK Bail-in Power with
respect to the Company, 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. If any of the events specified in each of the preceding
three sentences occurs, the Company shall promptly deliver notice to the Holders via DTC and to the Trustee and the Paying Agent directly, specifying the occurrence of the relevant event. 

Notwithstanding any other provision of this Security or the Sixth Supplemental Indenture, the Company may only redeem the Securities pursuant
to any of the preceding paragraphs relating to the Company’s rights of redemption or Sections 2.08, 2.09 and 2.10 of the Sixth Supplemental Indenture only if (i) the Company has obtained the Relevant Supervisory Consent, (ii) in
the case of a Special Event pursuant to Section 2.09 or Section 2.10 only, prior to the fifth anniversary of the Issue Date, if the Relevant Rules so oblige, the Company has demonstrated to the satisfaction of the Relevant Regulator that
(x) the Special Event was not reasonably foreseeable at the Issue Date and (y) in the case of a Tax Event, such Tax Event was material, (iii) the Company has complied with any alternative or additional
pre-conditions to redemption, as applicable, set out in the Relevant Rules and (iv) the Company has provided notice in accordance with the immediately preceding paragraph or Section 2.11 of the Sixth
Supplemental Indenture. 
 Notwithstanding any other provision of the Indenture, including Section 6.05 of the Base Indenture, members
of the HSBC Group may purchase, repurchase or otherwise acquire any of the Securities then Outstanding at the same or differing prices in the open market, negotiated transactions or otherwise without giving prior notice to or obtaining any consent
from Holders, in accordance with the Relevant Rules and subject to obtaining the Relevant Supervisory Consent. For the avoidance of doubt, the Securities may be repurchased by members of the HSBC Group for market-making purposes in accordance with
any permission given by the Relevant Regulator pursuant to the Relevant Rules (including, without limitation, Article 29(3) of Commission Delegated Regulation (EU) No. 241/2014) within the limits prescribed in such permission. 

  
 A-10 

 If a Capital Adequacy Trigger Event has occurred, then the Automatic Conversion shall occur
without delay, but no later than one (1) month following the date on which it is determined such Capital Adequacy Trigger Event has occurred (such date, the “Conversion Date”). Effective upon, and following, a Capital Adequacy
Trigger Event, other than any amounts payable in the case of the Company’s winding-up or the appointment of an administrator for its administration pursuant to Section 5.01 of the Sixth Supplemental
Indenture, Holders and Beneficial Owners shall not have any rights against the Company with respect to repayment of the principal amount of this Security or payments of interest or any other amount on, or in respect of, this Security, in each case
that is not due and payable, which liabilities shall be automatically released. Accordingly, the principal amount of this Security shall equal zero at all times thereafter and any interest shall be cancelled or deemed to have been cancelled pursuant
to the terms of this Security and Section 2.03 of the Sixth Supplemental Indenture at all times thereafter, including 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, and shall not be due and payable. Although the principal amount of each Security shall equal zero after a Capital Adequacy Trigger Event, for the avoidance of doubt, the Tradable Amount shall remain
unchanged as a result of the Automatic Conversion. 
 The number of Conversion Shares to be issued to the Conversion Shares Depository (or
the relevant recipient pursuant to Section 2.15 of the Sixth Supplemental Indenture) on the Conversion Date shall equal the quotient obtained by dividing the (i) aggregate principal amount of this Security then Outstanding immediately
prior to the Automatic Conversion on the Conversion Date (the “Outstanding Amount”) by (ii) the Conversion Price, rounded down, if necessary, to the nearest whole number of Conversion Shares. The number of Conversion Shares to
be held by the Conversion Shares Depository for the benefit of a Holder shall equal the product obtained by multiplying (i) the number of Conversion Shares thus calculated by (ii) the quotient obtained by dividing (x) the Tradable
Amount held by such Holder on the Conversion Date by (y) the Outstanding Amount, such product to be 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. 
 Effective upon, and following, an Automatic Conversion, all of
the Company’s obligations under this Security shall be irrevocably and automatically released in consideration of the Company’s issuance of the Conversion Shares to the Conversion Shares Depository (or the relevant recipient pursuant to
Section 2.15 of the Sixth Supplemental Indenture), and under no circumstances shall such released obligations be reinstated. 
 This
Security shall remain in existence until the applicable Cancellation Date for the sole purpose of evidencing 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) in accordance with the terms of this Security. 

The procedures with respect to an Automatic Conversion are set forth in this Security and the Sixth Supplemental Indenture, including
Section 2.15 thereof. Such procedures are subject to change to reflect changes in DTC practices, and the Company may make changes to the procedures set forth in this Security and Section 2.15 of the Sixth Supplemental Indenture to the
extent reasonably necessary, in the opinion of the Company, to reflect such changes in DTC practices. 
 The Holders and Beneficial Owners
shall not at any time have the option to convert to this Security into Conversion Shares. 

  
 A-11 

 Notwithstanding anything to the contrary contained in the Indenture or this Security, once the
Company has delivered an Automatic Conversion Notice following the occurrence of a Capital Adequacy Trigger Event (or following an Automatic Conversion (if sooner)), (i) subject to the right of Holders and Beneficial Owners pursuant to
Section 4.03 of the Sixth Supplemental Indenture in the event of a failure by the Company to issue and deliver any Conversion Shares to the Conversion Shares Depository on the Conversion Date, the Holders and Beneficial Owners shall have no
rights whatsoever under the Indenture or this Security to instruct the Trustee or the Paying Agent 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 sentence, with respect to any rights of Holders or Beneficial Owners with respect to any payments under this Security that were unconditionally due and payable prior to the date of the
Automatic Conversion Notice or unless the Trustee or the Paying Agent is instructed in writing by the Company to act otherwise. 
 Neither
the Trustee nor the Paying Agent shall be liable with respect to (i) the calculation or accuracy of the End-point 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 End-point CET1 Ratio calculations of a Capital Adequacy Trigger Event to DTC, the Holders
or the Beneficial Owners or (iii) any aspect of the Company’s decision to deliver an Automatic Conversion Notice or the related Automatic Conversion. 

Notwithstanding any other provision herein, by its acquisition of this Security, each Holder (which, for these purposes, includes each
Beneficial Owner) (i) consents to all of the terms and conditions of the Securities, including (x) the occurrence of a Capital Adequacy Trigger Event and any related Automatic Conversion following a Capital Adequacy Trigger Event and
(y) the appointment of the Conversion Shares Depository (or to the relevant recipient pursuant to Section 2.15 of the Sixth Supplemental Indenture), the issuance of the Conversion Shares to the Conversion Shares Depository (or to the
relevant recipient pursuant to Section 2.15 of the Sixth Supplemental Indenture),) and the potential sale of the Conversion Shares pursuant to a Conversion Shares Offer, (ii) acknowledges and agrees that effective upon, and following, a
Capital Adequacy Trigger Event, other than any amounts payable in the case of the Company’s winding-up or the appointment of an administrator for its administration pursuant to Section 5.01 of the
Sixth Supplemental Indenture, no Holder shall 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 on or in respect of this Security, in each case that is
not due and payable, which liabilities of the Company shall be automatically released, (iii) acknowledges and agrees that events in, and related to, clause (i) may occur without any further action on the part of such Holder, the Trustee or
the Paying Agent, (iv) authorizes, directs and requests DTC and any direct participant in DTC or other intermediary through which it holds such Securities to take any and all necessary action, if required, to implement the Automatic Conversion
without any further action or direction on the part of such Holder, the Trustee or the Paying Agent and (v) 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. 

Following the occurrence of an Automatic Conversion, the Company, in its sole and absolute discretion, may elect in the Conversion Shares
Office Notice that the Conversion Shares Depository make an offer of all or some of the Conversion Shares to all or some of the Shareholders at a cash price per Conversion Share equal to the Conversion Shares Offer Price (the “Conversion
Shares Offer”), subject to, and in accordance with, the terms of the Indenture. 

  
 A-12 

 The Conversion Price and the Conversion Shares Offer Price shall be subject to adjustment as
provided in Article III of the Sixth Supplemental Indenture. 
 If the Company elects, in its sole and absolute discretion, that a
Conversion Shares Offer be conducted, each Holder (which, for these purposes, includes each Beneficial Owner, by its acquisition of this Security, shall: (i) consent to (x) any Conversion Shares Offer and to the Conversion Shares
Depository’s using the Conversion Shares to settle any Conversion Shares Offer in accordance with the terms of this Security, notwithstanding that such Conversion Shares are held by the Conversion Shares Depository on behalf of Holders and
Beneficial Owners 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 this Security, and
(ii) irrevocably agree that (x) the Company, the Conversion Shares Depository (or the relevant recipient pursuant to Section 2.15 of the Sixth Supplemental Indenture) and the Conversion Shares Offer Agent, if any, may take any and all
actions necessary to conduct the Conversion Shares Offer in accordance with the terms of the Securities, and (y) none of the Company, the Trustee, the Paying Agent, 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). 
 Delivery of the Conversion Shares or Conversion Shares
Offer Consideration, as applicable, to the Holders and Beneficial Owners shall be made in accordance with the procedures set forth in Section 2.18 of the Sixth Supplemental Indenture, which remain subject to change to reflect changes in
DTC’s practices. 
 By its acquisition of the Securities, each Holder (which, for these purposes, includes each Beneficial Owner): (i)
acknowledges, accepts, consents and agrees, notwithstanding any other term of the Securities, the Indenture or any other agreements, arrangements or understandings between the Company 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 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 Company’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 Securities or the Indenture; (iii) the cancellation of the Securities; and/or (iv) the amendment or
alteration of the redemption date of the Securities or amendment of the amount of interest payable on the Securities, or the Interest Payment Dates, including by suspending payment for a temporary period; and (y) the variation of the terms of
the Securities or the Indenture, if necessary, to give effect to the exercise of any UK Bail-in Power by the Relevant UK Resolution Authority and (ii) consents to the exercise of any UK Bail-in Power as it may be imposed without any prior notice by the Relevant UK Resolution Authority of its decision to exercise such power with respect to the Securities. 

Notwithstanding anything to the contrary in the Indenture or this Security, including Article 9 of the Base Indenture, the Company hereby
agrees that it shall not amend the immediately preceding paragraph or Section 2.20(a) of the Sixth Supplemental Indenture without the prior consent of the Relevant Regulator. 

  
 A-13 

 By its acquisition of the Securities, each Holder (which, for these purposes, includes each
Beneficial Owner): (i) acknowledges and agrees that neither a Capital Adequacy Trigger Event, an Automatic Conversion, a reduction or cancellation, in part or in full, of the Amounts Due (including pursuant to Sections 2.03 and 2.04 of the Sixth
Supplemental Indenture), the conversion thereof into another security or obligation of the Company or another Person, as a result of the exercise of the UK Bail-in Power by the Relevant UK Resolution Authority
with respect to the Securities, nor the exercise of the UK Bail-in Power by the Relevant UK Resolution Authority with respect to the Securities shall 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; (ii) 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 the UK Bail-in Power by the Relevant UK Resolution Authority with respect to the Securities; (iii) acknowledges and agrees that, upon the exercise of any UK Bail-in Power by the Relevant UK Resolution Authority (a) the Trustee shall not be required to take any further directions from Holders under Section 5.12 of the Base Indenture and (b) none of the
Base Indenture or the Sixth Supplemental Indenture shall impose any duties upon the Trustee whatsoever with respect to the exercise of any UK Bail-in Power by the Relevant UK Resolution Authority; and
(iv) shall be deemed to have authorized, directed and requested DTC and any direct participant in DTC or other intermediary through which it holds such Securities to take any and all necessary action, if required, to implement the exercise of
any UK 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, the Trustee or the Paying Agent. 

Upon the exercise of the UK Bail-in Power by the Relevant UK Resolution Authority with respect to the
Securities, the Company shall provide a written notice to Holders through DTC as soon as practicable regarding such exercise of the UK Bail-in Power. The Company shall also deliver a copy of such notice to the
Trustee for information purposes. 
 The Company’s obligations to indemnify the Trustee in accordance with Section 6.07 of the
Base Indenture shall survive any Automatic Conversion with respect to this Security. 
 It is the Parties’ intention that the
Company’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 with
respect to this Security. 
 In addition to the right to enter into supplemental indentures pursuant to Sections 9.01 and 9.02 of the Base
Indenture, the Company and the Trustee may enter into one or more indentures supplemental to the Indenture to modify and amend the terms of the Indenture or this Security, 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. 
 The
exercise of the UK Bail-in Power by the Relevant UK Resolution Authority with respect to this Security shall not constitute a Winding-Up Event or a Non-Payment Event. 
 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 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. 

  
 A-14 

 If a Winding-Up Event occurs before the occurrence of a
Capital Adequacy Trigger Event, the principal amount of the Securities 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 the Company fails to pay any amount that has become due and payable under the Securities, the Paying Agent shall notify the Trustee and, if
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 in accordance with the Indenture, 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 the terms of this Security or Section 2.03 or 2.04 of the Sixth Supplemental Indenture, the Company cancels any interest payment in respect of
any Interest Payment Date or if such interest payment is deemed to have been 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 shall 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 Section 4.02 of the Sixth
Supplemental Indenture, the Trustee may without further notice institute such proceedings against the Company as it 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 payment of any principal or interest, including Additional Amounts) (such obligation, a “Performance Obligation”);
provided the sole and exclusive remedy that the Trustee (acting on behalf of the Holders) and/or the Holders may seek under the Securities and the Indenture is specific performance under the laws of the State of New York;
provided further that to the extent any judgment or other award given in such proceedings requires the payment of money by the Company, whether by way of damages or otherwise (a “Monetary Judgment”), the Trustee
(acting on behalf of the Holders) and/or the Holders may not enforce, and shall not be entitled to enforce, or otherwise claim such Monetary Judgment against the Company, except by proving such Monetary Judgment in the
winding-up or administration of the Company. For the avoidance of doubt, any breach by the Company of any Performance Obligation shall not confer upon the Trustee (acting on behalf of the Holders) and/or the
Holders any claim other than specific performance and the Company shall not be obliged to pay any sum or sums, in cash or otherwise (including damages), as a consequence of the institution of any such proceedings, except where a Holder proves any
Monetary Judgment in the Company’s winding-up or administration. 
 Other than the limited
remedies specified in this Security and Article IV of the Sixth Supplemental Indenture, and subject to the second paragraph following this sentence, no remedy against the Company shall be available to the Trustee (acting on behalf of the
Holders) and to the Holders and Beneficial Owners, whether for the recovery of amounts owing in respect of this Security 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 this Security 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 5.06 of the Base Indenture expressly survive any Default and are not subject to the subordination provisions of Section 5.01 of the Sixth
Supplemental Indenture and the corresponding provisions of this Security. 

  
 A-15 

 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
(i) upon the occurrence of a Winding-Up Event that occurs before the Conversion Date or (ii) upon the occurrence of a Non-Payment Event or (iii) upon a
breach by the Company of a Performance Obligation. Neither a Capital Adequacy Trigger Event, an Automatic Conversion, a cancellation or deemed cancellation of interest (in each case, in whole or in part) in accordance with the terms of the Indenture
and this Security nor the exercise of the UK Bail-in Power by the Relevant UK Resolution Authority with respect to this Security shall be stated to be an Event of Default or a Default. 

Notwithstanding the limitations on remedies specified in this Security and under Article IV of the Sixth Supplemental Indenture,
(i) 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 under the provisions of the Indenture, and (ii) nothing shall impair
the right of a Holder or Beneficial Owner 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 this Security; provided that, in the case of
(i) and (ii) above, any payments in respect of, or arising from, this Security, including any payments or amounts resulting or arising from the enforcement of any rights under the Trust Indenture Act in respect of this Security, shall be
subject to the subordination provisions set forth in Section 5.01 of the Sixth Supplemental Indenture and the corresponding provisions of this Security. 

Holders of not less than a majority in aggregate principal amount of the Securities then Outstanding may on behalf of the Holders of all of
the Securities waive any past Default that results from a breach by the Company of a Performance Obligation; provided that (i) a Default in respect of a Performance Obligation, the modification or amendment of which would require the
consent of each Holder affected by it or (ii) any past Default that results from a Winding-Up Event or a Non-Payment Event, in either case, will require the waiver
of each Holder affected by such Default. Upon the occurrence of any waiver permitted by the immediately preceding sentence, such Default shall cease to exist, and any Default with respect to any series arising therefrom shall be deemed to have been
cured and not to have occurred for every purpose of the Base Indenture, but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. 

This Security shall constitute the Company’s direct, unsecured and subordinated obligations, ranking equally without any preference among
themselves. The rights and claims of the Holders and Beneficial Owners in respect of or arising from this Security shall be subordinated to the claims of Senior Creditors. If (x) 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 of the Company, the terms of
which reorganization, reconstruction or amalgamation (i) have previously been approved in writing by a majority of the Holders and (ii) do not provide that this Security shall thereby become redeemable or repayable in accordance with the
terms of this Security); or (y) following the appointment of an administrator for the Company’s administration, the administrator declares, or gives notice that it intends to declare and distribute, a dividend, then (i) if such events
specified in (x) or (y) occur prior to the date on which a Capital Adequacy Trigger Event occurs, there shall be payable by the Company in respect of this Security (in lieu of any other payment by the Company), such amount, if any, as
would have been payable to a Holder if, on the day prior to the commencement of such winding-up or such administration and thereafter, such Holder were the holder of the most senior class of preference shares
in the Company’s capital, having an equal right to a return of assets in such 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 of assets in such 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 Company’s capital, but ranking junior to the claims of Senior Creditors, and on the assumption that the amount that such Holder was entitled to receive in respect of such senior preference shares, on a
return of assets in such winding-up or such administration, 

  
 A-16 

 
were an amount equal to the principal amount of the relevant Security, together with any accrued but unpaid interest thereon (to the extent not cancelled or deemed to have been cancelled) and any
Monetary Judgment (if payable); and (ii) if such events specified in (x) or (y) above occur on or after the date on which a Capital Adequacy Trigger Event occurs but prior to the Conversion Date, there shall be payable by the Company
in respect of this Security (in lieu of any other payment by the Company) such amount, if any, as would have been payable to a Holder on a return of assets in such winding-up or such administration if the
Conversion Date in respect of an Automatic Conversion had occurred immediately prior to the occurrence of such events specified in (x) or (y) above (and as a result, such Holder were the holder of such number of Ordinary Shares as such
Holder would have been entitled to receive on the Conversion Date, ignoring for these purposes the Company’s right to elect to make a Conversion Shares Offer). 

Other than in the event of a winding-up or administration of the Company as described in the
immediately preceding paragraph, payments in respect of or arising from this Security 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 this Security 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, 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 (i) it is able to pay its debts owed to Senior Creditors as they fall due and (ii) the Balance Sheet Condition has been met. A
certificate by the Auditors as to whether or not the Solvency Condition is met, on the basis of the information provided to the Auditors by the Company, will, in the absence of manifest error, be treated by the Company, the Trustee, the Holders, the
Beneficial Owners and all other interested parties as correct and sufficient evidence thereof. 
 The Indenture contains provisions
permitting the Company and the Trustee (i) without the consent of the Holders of any Contingent Convertible 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 Securities, and (ii) with the consent of the Holders of not less than a majority in aggregate principal amount of the Outstanding Contingent Convertible Securities of each series of Contingent Convertible
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; provided that, with respect to certain enumerated provisions, no such supplemental indenture may be entered into without the consent of the Holder of each Outstanding Contingent Convertible Security affected thereby. The
Indenture also permits the Holders of at least a majority in aggregate principal amount of the Outstanding Contingent Convertible Securities of each series to be affected, on behalf of the Holders of all Contingent Convertible Securities of such
series, to waive compliance by the Company with certain restrictive provisions of the Indenture. Any such consent or waiver by the Holder of this Security shall bind every future Holder 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 or such other Securities. 

No Holder shall 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 hereunder, unless (a) such Holder has previously given written notice to the Trustee of a continuing Default specifying such Default and stating that such notice is a “Notice of Default”
under the Indenture; (b) the Holders of not less than 25% in aggregate principal amount of the Outstanding Securities of this series shall have made written request to the Trustee to institute proceedings in respect of such Default in its own
name, as Trustee hereunder; (c) such Holder has offered to the Trustee security or indemnity satisfactory to the Trustee in its sole discretion against the costs, expenses and liabilities to be incurred in compliance with

  
 A-17 

 
such request; (d) the Trustee for sixty (60) days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and (e) no direction
inconsistent with such written request has been given to the Trustee during such sixty-day (60-day) period by the Holders of a majority in aggregate principal amount of
the Outstanding Securities of this series; it being understood and intended that no one or more Holders of this series shall have any right in any manner whatsoever by virtue of, or by availing of, any provision of the Indenture to affect, disturb
or prejudice the rights of any other such Holders or holders, or to obtain or to seek to obtain priority or preference over any other such Holders or holders or to enforce any right under the Indenture, except in the manner herein provided and for
the equal and ratable benefit of all Holders of this series. 
 Subject to the terms of the Indenture, the Depository may surrender this
Global Security or any portion thereof in exchange in whole or in part for definitive Security on such terms as are acceptable to the Company and the Depository. Thereupon, the Company shall execute, and the Trustee shall authenticate and deliver
such definitive Securities to the Registrar. In turn, the Registrar shall deliver such definitive Securities, without service charge, as provided in the Indenture. 

All covenants and agreements in the Base Indenture, as supplemented and amended by the Sixth Supplemental Indenture, by the Company shall bind
its successors and assigns, whether so expressed or not. 
 The Holders (which, for these purposes, includes Beneficial Owners) that acquire
the Securities in the secondary market and any successors, assigns, heirs, executors, administrators, trustees in bankruptcy and legal representatives of any Holder shall be deemed to acknowledge, accept, agree to be bound by and consent to the same
provisions specified herein and in the Indenture to the same extent as the Holders 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 related to the UK Bail-in Power and related to a Capital Adequacy Trigger Event. 

This Security and the Sixth Supplemental Indenture shall be governed by, and construed in accordance with, the laws of the State of New York,
except that Article V of the Sixth Supplemental Indenture and the corresponding provision in this Security are governed by, and construed in accordance with, the laws of England and Wales.

This notice is in relation to HSBC Holdings plc’s (the “Company”) $2,350,000,000 6.250% Perpetual Subordinated Contingent Convertible
Securities (Callable March 23, 2023 and Every Five Years Thereafter) (CUSIP: 404280 BN8, ISIN: US404280BN80) issued on March 23, 2018 (the “Securities”) pursuant to the Contingent Convertible Securities Indenture,
dated as of August 1, 2014 (as amended and supplemented from time to time), among the Company, The Bank of New York Mellon, London Branch, as trustee (the “Trustee”), and HSBC Bank USA, National Association
(“HBUS”), as registrar and paying agent, as supplemented by the Sixth Supplemental Indenture, dated March 23, 2018, among the Company, the Trustee and HBUS, as registrar, paying agent and calculation agent (together, the
“Indenture”), and pursuant to the prospectus supplement dated March 19, 2018, supplementing the prospectus dated February 23, 2018. Capitalized terms used herein and not defined herein shall have the respective meanings
ascribed to such terms in the Indenture.

 B-1 

 The Company hereby notifies DTC, the Holders and Beneficial Owners that a Capital Adequacy Trigger Event has
occurred with respect to the Securities. Such Capital Adequacy Trigger Event has occurred because the End-point CET1 Ratio as of [Date of Capital Adequacy Trigger Event] was less than 7.0% . 

Upon the occurrence of a 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] [Conversion Date], based on the Conversion Price, which is [Conversion Price]. Upon the Automatic Conversion, all of the Company’s obligations under the Securities shall be irrevocably and
automatically released in consideration of the Company’s issuance of ordinary shares of the Company (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 right to receive Conversion Shares or the Conversion Shares Offer Consideration, as applicable, from the
Conversion Shares Depository (or the relevant recipient in accordance with the terms of the Securities). 
 In addition, the terms of the Securities provide
that the Company may, in its sole and absolute discretion, elect that a Conversion Shares Offer be conducted. Within ten (10) Business Days of the Conversion Date, the Company shall deliver to DTC, the Holders and the Beneficial Owners a
Conversion Shares Offer Notice specifying, among other things, whether or not the Company has elected that a Conversion Shares Offer be conducted and the Suspension Date. The Securities may continue to trade until the Suspension Date. 

Accordingly, the Company hereby instructs DTC to indicate to all participants that payments of principal and interest are no longer payable under the
Securities as of [Date of Capital Adequacy Trigger Event] and that the Securities shall have no further entitlement to interest or principal as of such date by making a note to that effect in its systems. 

The Company further requests DTC to post this notice on its Reorganization Inquiry for Participants System (or such other system as DTC uses for providing
notices to holders of securities).

(f) The Securities shall be issued on March 23, 2018 (the “Issue Date”). 

  
 16 

 (g) The Securities shall have no fixed maturity and shall not be redeemable except as provided in
Sections 2.08, 2.09 and 2.10 hereof. 
 (h) The interest rate on the Securities shall be determined as set forth in Section 2.02(a)
hereof. 
 (i) The Securities shall be issued in denominations of $200,000 in principal amount and integral multiples of $1,000 in excess
thereof. 
 (j) The denomination of each interest in a 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 equal such Global Security’s outstanding principal amount. Following an Automatic Conversion, the principal amount of each
Security shall equal zero, but the Tradable Amount of the book-entry interests in each Security shall remain unchanged as a result of the Automatic Conversion. 

SECTION 2.02. Interest. 

(a) From (and including) the Issue Date to (but excluding) March 23, 2028, the interest rate on the Securities shall be 6.500% per annum.
From (and including) each Reset Date to (but excluding) the next following Reset Date, the applicable per annum interest rate shall be equal to the sum of the applicable Mid-Market Swap Rate on the relevant
Reset Determination Date and 3.606%. Subject to Sections 2.03 and 2.04, interest, if any, shall be payable in two equal semi-annual installments in arrear on March 23 and September 23 of each year (each, an “Interest Payment
Date”); provided that if such 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. Subject to Sections 2.03 and 2.04, interest on the Securities, if any, shall be computed and payable in arrear and on the basis of a year of 360 days consisting of twelve (12) months of thirty (30) days each and, in the case of an
incomplete month, the actual number of days elapsed. The first date on which interest may be paid shall be September 23, 2018 for the period commencing on (and including) the Issue Date and ending on (but excluding) September 23, 2018. If
a date of redemption or repayment is not a Business Day, the Company may pay interest (if any) together with the principal on the next succeeding Business Day; provided that interest shall not accrue during the period from and after the date
of redemption. The “Regular Record Date” shall be the close of business (local time in the place of the Register) on the fifteenth (15th) calendar day prior to the relevant
Interest Payment Date. 
 (b) If any Reset Date is not a Business Day, the Reset Date shall occur on the next succeeding Business Day. For
the avoidance of doubt, if the Reset Date is not a Business Day and accordingly the Reset Date occurs on the next Business Day (the “Adjusted Reset Date”), then the equal semi-annual payment of interest (if paid) on the next
Interest Payment Date shall reflect interest for the entire interest period (including any portion of such interest period occurring between the originally scheduled Reset Date and the Adjusted Reset Date) at the interest rate determined based on
the Adjusted Reset Date, and not at the interest rate that applied to the immediately preceding semi-annual interest period. In addition and for the avoidance of doubt, in connection with any optional redemption of the Securities pursuant to
Section 2.08, if the Reset Date is not a Business Day, as described above, the Company may pay the interest (if any) together with the principal on the Adjusted Reset Date, but interest on that payment shall not accrue during the period from
and after the last Interest Payment Date. 
 (c) The Company shall promptly give notice of the determination of the Alternative Base Rate and
any adjustment factors to the Trustee, the Agent and the Holders. 

  
 17 

 (d) By its acquisition of the Securities, each Holder (which, for these purposes includes each
Beneficial Owner) (i) waives any and all claims, in law and/or in equity, against the Trustee and the Agent for, agrees not to initiate a suit against the Trustee and the Agent in respect of, and agrees that neither the Trustee nor the Agent
shall be liable for, the determination of or the failure to determine any Alternative Base Rate (including any adjustments thereto) and any losses suffered in connection therewith, and (ii) agrees that neither the Trustee nor the Agent shall
have any obligation to determine any Alternative Base Rate (including any adjustments thereto), including in the event of any failure by the Company to determine any Alternative Base Rate. 

(e) All determinations and any calculations made by the Calculation Agent for the purposes of calculating the applicable Mid-Market Swap Rate shall be conclusive and binding on the Holders, the Company, the Trustee and the Paying Agent, absent manifest error. The Calculation Agent shall not be responsible to the Company, the Holders
or any third party for any failure of the Reference Banks to provide quotations as requested of them or as a result of the Calculation Agent having acted on any quotation or other information given by any Reference Bank which subsequently may be
found to be incorrect or inaccurate in any way. 
 (f) In addition to any other restrictions on payments of principal and interest contained
in this Seventh Supplemental Indenture, 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. 
 SECTION 2.03.
Interest Payments Discretionary. 
 (a) 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 (the “Discretionary Interest
Payment Right”). 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. For the avoidance of doubt, 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. 
 (b) Interest shall
only be due and payable on an Interest Payment Date to the extent it is not cancelled or deemed to have been cancelled (in each case, in whole or in part) in accordance with the provisions set forth in Sections 2.03(a) and 2.04, and any interest
cancelled or deemed to have been cancelled (in each case, in whole or in part) pursuant to such Sections shall not be due and shall not accumulate or be payable at any time thereafter, and Holders and Beneficial Owners shall have no rights thereto
or to receive any additional interest or compensation as a result of such cancellation or deemed cancellation. 
 SECTION 2.04.
Restriction on Interest Payments. 
 (a) Without prejudice to the provisions of Section 2.03 or the prohibition contained in
Article 141(2) of CRD (and any implementation of such provision in the UK or, as the case may be, any 

  
 18 

 succeeding provision amending or replacing such Article or any such implementing provision) on the making of
payments on the Securities before the Maximum Distributable Amount has been calculated, subject to the extent permitted in clause (b) below 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: 

(i) the amount of Relevant Distributions exceeds the amount of Distributable Items as of such Interest Payment Date; 

(ii) the aggregate of (x) the interest amount payable in respect of the Securities and (y) the amounts of any
distributions of the kind referred to in Article 141(2) of CRD (and any implementation of such provision in the UK or, as the case may be, any succeeding provision amending or replacing such Article or any such implementing provision) exceeds the
Maximum Distributable Amount (if any) applicable to the Company as of such Interest Payment Date; 
 (iii) the Solvency
Condition is not satisfied in respect of such interest payment; or 
 (iv) the Relevant Regulator orders the Company to
cancel (in whole or in part) the interest otherwise payable on such Interest Payment Date; 
 (b) 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 restriction of clause (a) above. For the avoidance of
doubt, the portion of interest not paid on the relevant Interest Payment Date shall be deemed to have been cancelled and thus shall not be due and payable on such Interest Payment Date. 

SECTION 2.05. Agreement to Interest Cancellation. By its acquisition of the Securities, each Holder (which, for these purposes includes
each Beneficial Owner) acknowledges and agrees that: 
 (a) 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 to have been
cancelled (in whole or in part), including as a result of the Distributable Items or the Maximum Distributable Amount being exceeded, failing to satisfy the Solvency Condition under Section 2.04 or an order from the Relevant Regulator; and 

(b) a cancellation or deemed cancellation of interest (in each case, in whole or in part) in accordance with the terms of the Indenture and the
Securities shall not constitute a default in payment or otherwise under the terms of the Securities or the Indenture. 
 SECTION 2.06.
Notice of Interest Cancellation. If practicable, the Company shall provide notice of any cancellation or deemed cancellation of interest (in each case, in whole or in part) to the Holders, in the case of Global Securities, via DTC (or, if the
Securities are definitive Securities, to the Holders at their addresses shown on the Register) and to the Trustee and the Paying Agent directly on or prior to the relevant Interest Payment Date. If practicable, the Company shall endeavor to do so at
least five (5) Business Days prior to the relevant Interest Payment Date. Failure to provide such notice shall have no impact on the effectiveness of, or otherwise invalidate, any such cancellation or deemed cancellation of interest (and
accordingly, such interest shall not be due and payable, as provided in Section 2.03), or give the Holders or Beneficial Owners any rights as a result of such failure. 

  
 19 

 SECTION 2.07. Payment of Principal, Interest and Other Amounts. Payments of principal of
and interest, if any, on the Securities shall be made in dollars and such payments on Securities represented by a Global Security shall be made through one or more Paying Agents appointed under the Base Indenture to DTC or its nominee, as the Holder
or Holders of the Global Security. Initially, the Paying Agent shall be HSBC Bank USA, National Association. The Company may change the Paying Agent without prior notice to the Holders, and in such an event the Company may act as Paying Agent.
Payments of principal of and interest on the Securities represented by a 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. 
 SECTION 2.08. Optional Redemption. Subject to the limitations specified in
Section 2.12, the Company may, at the Company’s option in its sole discretion, redeem the Securities, in whole (but not in part), on any 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 to have been cancelled as described in Sections 2.03 and 2.04) to (but excluding) the date fixed for redemption. 

SECTION 2.09. Optional Tax Redemption. 

(a) Subject to Section 2.12, the Company may, at the Company’s option in its sole discretion, 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 to have been cancelled as described in Sections
2.03 and 2.04) to (but excluding) the date fixed for redemption, if, at any time, the Company determines that as a result of a change in, or amendment to, the laws of a Taxing Jurisdiction, including any treaty to which the relevant Taxing
Jurisdiction is a party, or a change in an official application or interpretation of those laws on or after the Issue Date, including a decision of any court or tribunal that becomes effective on or after the Issue Date: 

(i) on a subsequent date for the payment of interest on the Securities the Company would be required to pay any Additional
Amounts; 
 (ii) if the Company were to seek to redeem the Securities on a subsequent date (for which purpose no
consideration shall be given as to whether or not the Company would otherwise be entitled to redeem the Securities), the Company would be required to pay any Additional Amounts (notwithstanding the Company having made such endeavors as the Company
considers reasonable); 
 (iii) on a subsequent date for the payment of interest on the Securities, interest payments (or the
Company’s funding costs as recognized in the Company’s accounts) under, or with respect to, the Securities are no longer fully deductible for UK corporation tax purposes; 

(iv) the Securities would no longer be treated as loan relationships for UK tax purposes; 

(v) would, as a result of the Securities being in issue, result in the Company not being able to have losses or deductions set
against the profits or gains, or profits or gains offset by the losses or deductions, of companies with which it is or would otherwise be so grouped for applicable UK tax purposes (whether under the group relief system current as of the Issue Date
or any similar system or systems having like effect as may from time to time exist); 

  
 20 

 (vi) a future write-down of the principal amount of the Securities or conversion
of the Securities into the Ordinary Shares would result in a UK tax liability, or the receipt of income or profit which would be subject to UK tax, which would not otherwise have been the case as of the Issue Date; or 

(vii) the Securities or any part thereof become treated as a derivative or an embedded derivative for UK tax purposes 

(each such change (or deemed change) in tax law or regulation or the official application or interpretation thereof, a “Tax Event”). 

(b) Subject only to the Company’s obligation to use such endeavors as provided in Section 2.09(a)(ii), it shall be sufficient for the
Company to deliver to the Trustee an Officer’s Certificate stating that a Tax Event has occurred and is continuing and setting out the details thereof, as well as any opinion or certificate of an independent legal adviser on which such
Officer’s Certificate is based. 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 shall be conclusive and binding on the Holders and Beneficial Owners. 
 SECTION 2.10. Capital Disqualification Event
Redemption. 
 Subject to Section 2.12, the Company may, at the Company’s option in its sole discretion, 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 to have been cancelled as
described in Sections 2.03 and 2.04) to (but excluding) the date fixed for redemption, if the Company determines, at any time after the Issue Date, there is a change in the regulatory classification of the Securities that results or shall result in
either their (i) exclusion in whole or in part from the HSBC Group’s regulatory capital (other than as a consequence of an Automatic Conversion); or (ii) reclassification in whole or in part as a form of the HSBC Group’s
regulatory capital that is lower than additional Tier 1 capital (a “Capital Disqualification Event”). 
 SECTION 2.11.
Notice of Redemption. 
 (a) Before the Company may redeem the Securities pursuant to Section 2.08, 2.09 or 2.10, the Company
shall deliver via DTC (or, if the Securities are definitive Securities, to the Holders at their addresses shown on the Register) prior notice of not less than thirty (30) days, nor more than sixty (60) days to the Holders; provided,
however, that in the case of a Tax Event, no notice of redemption shall be given earlier than 90 days prior to the earliest date on which the Company would be obliged to pay Additional Amounts were a payment in respect of the Securities then
due. Such notice shall specify the 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 clauses (b), (c) and (d) of this
Section 2.11. 
 (b) If the Company has delivered a notice of redemption pursuant to clause (a) of this Section 2.11, but as
of the date specified for redemption in such notice, the Solvency Condition is not satisfied in respect of the relevant redemption payment, 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 the Company has delivered a notice of redemption pursuant to clause
(a) of this Section 2.11, but prior to the payment of the redemption amount with respect to such redemption a Capital Adequacy Trigger Event occurs, such redemption notice shall be automatically rescinded and shall be of no force and
effect, no payment in respect of the redemption amount shall be due and payable (and, for the avoidance of doubt, an Automatic Conversion shall occur after such Capital Adequacy Trigger Event pursuant to Section 2.15(a)). 

  
 21 

 (d) If the Company has delivered a notice of redemption pursuant to clause (a) of this
Section 2.11, but prior to the payment of the redemption amount with respect to such redemption the Relevant UK Resolution Authority exercises its UK Bail-in Power with respect to the Company, 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. 

(e) If any of the events specified in clauses (b), (c) and (d) of this Section 2.11 occurs, the Company shall promptly deliver notice
to the Holders, in the case of Global Securities, via DTC (or, if the Securities are definitive Securities, to the Holders at their addresses shown on the Register) and to the Trustee and the Paying Agent directly, specifying the occurrence of the
relevant event. 
 SECTION 2.12. Limitations on Redemption. Notwithstanding any other provision of the Seventh Supplemental
Indenture, the Company may redeem the Securities pursuant to Sections 2.08, 2.09 and 2.10 only if (i) the Company has obtained the Relevant Supervisory Consent, (ii) in the case of a Special Event pursuant to Section 2.09 or
Section 2.10 only, prior to the fifth anniversary of the Issue Date, if the Relevant Rules so oblige, the Company has demonstrated to the satisfaction of the Relevant Regulator that (x) the Special Event was not reasonably foreseeable at
the Issue Date and (y) in the case of a Tax Event, such Tax Event was material, (iii) the Company has complied with any alternative or additional pre-conditions to redemption, as applicable, set out
in the Relevant Rules and (iv) the Company has provided notice in accordance with Section 2.11. 
 SECTION 2.13. Cancelled
Interest Not Payable Upon Redemption. Any interest payments that have been cancelled or deemed to have been cancelled pursuant to Sections 2.03 or 2.04 shall not be payable if the Securities are redeemed pursuant to Section 2.08, 2.09 or
2.10. 
 SECTION 2.14. Purchases. Notwithstanding any other provision of the Indenture, including Section 6.05 of the Base
Indenture, members of the HSBC Group may purchase, repurchase or otherwise acquire any of the Securities then Outstanding at the same or differing prices in the open market, negotiated transactions or otherwise without giving prior notice to or
obtaining any consent from Holders, in accordance with the Relevant Rules and subject to obtaining the Relevant Supervisory Consent. For the avoidance of doubt, the Securities may be repurchased by members of the HSBC Group for market-making
purposes in accordance with any permission given by the Relevant Regulator pursuant to the Relevant Rules (including, without limitation, Article 29(3) of Commission Delegated Regulation (EU) No. 241/2014) within the limits prescribed in such
permission. 
 SECTION 2.15. Automatic Conversion upon Capital Adequacy Trigger Event. 

(a) If a Capital Adequacy Trigger Event has occurred, then the Automatic Conversion shall occur without delay, but no later than one
(1) month following the date on which it is determined such Capital Adequacy Trigger Event has occurred (such date, the “Conversion Date”). Whether a Capital Adequacy Trigger Event has occurred at any time shall be determined
by the Company, the Relevant Regulator or any agent of the Relevant Regulator appointed for such purpose by the Relevant Regulator. Effective upon, and following, a Capital Adequacy Trigger Event, other than any amounts payable in the case of the
Company’s winding-up or the appointment of an administrator for its administration pursuant to Section 5.01, Holders and Beneficial Owners shall not have any rights against the Company with respect
to repayment of the principal amount of the Securities or payments of interest or any other amount on, or in respect of, the Securities, in each case that is not due and payable, which liabilities shall be automatically 

  
 22 

 released. Accordingly, the principal amount of the Securities shall equal zero at all times thereafter and any
interest shall be cancelled or deemed to have been cancelled pursuant to Section 2.03 at all times thereafter, including 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, and shall not be due and payable. Although the principal amount of each Security shall equal zero after a Capital Adequacy Trigger Event, for the avoidance of doubt, the Tradable Amount shall remain
unchanged as a result of the Automatic Conversion. 
 Effective upon, and following, the Conversion Date, all of the Company’s
obligations under the Securities shall be irrevocably and automatically released in consideration of the Company’s issuance of the Conversion Shares to the Conversion Shares Depository (or the relevant recipient pursuant to this
Section 2.15), and under no circumstances shall such released obligations be reinstated. 
 While any Security remains Outstanding, the
Company shall at all times keep available for issue, free from preemptive or other preferential rights, sufficient ordinary shares to enable an Automatic Conversion to be satisfied in full. 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 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, distributions or
payments, the entitlement to which falls prior to the Conversion Date. 
 The Conversion Shares shall initially be registered in the name of
the Conversion Shares Depository (or the relevant recipient pursuant to this Section 2.15) (which shall hold the Conversion Shares on behalf of the Holders and Beneficial Owners), 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). 

The Conversion Shares Depository (or the relevant recipient pursuant to this Section 2.15) shall hold the Conversion Shares on behalf of
the Holders and Beneficial Owners, who shall be entitled to direct the Conversion Shares Depository or such other relevant recipient, as applicable, to exercise on their behalf all rights of a Shareholder (including voting rights and rights to
receive dividends); provided, however, that Holders and Beneficial Owners shall not have any rights 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 2.18. 
 The Securities shall remain in existence until the
applicable Cancellation Date for the sole purpose of evidencing 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) in accordance with the terms of the Securities. 
 With effect from the Conversion Date, Holders
and Beneficial Owners shall have recourse only to the Conversion Shares Depository (or to the relevant recipient pursuant to this Section 2.15) 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. If the Company fails to issue and deliver the Conversion Shares to the Conversion Shares Depository in accordance with the terms of
the Securities and the Indenture, the only right of the Holders and Beneficial Owners against the Company shall be to claim to have such Conversion Shares issued to the Conversion Shares Depository. 

  
 23 

 If the Company has been unable to appoint a Conversion Shares Depository, it shall effect, by
means it deems reasonable in the circumstances (including, without limitation, issuance of the Conversion Shares to another nominee or to the Holders directly), the issuance and/or delivery of the Conversion Shares or Conversion Shares Offer
Consideration, as applicable, to the Holders, and such issuance shall irrevocably and automatically release all of the Company’s obligations under the Securities as if the Conversion Shares had been issued to the Conversion Shares Depository.

 (b) The Company shall (a) immediately inform the Relevant Regulator of the occurrence of a Capital Adequacy Trigger Event and
(b) deliver an Automatic Conversion Notice on or as soon as practicable after the date on which it is determined such Capital Adequacy Trigger Event has occurred. 

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 DTC (or, if the Securities are definitive Securities, to the Trustee). 
 The Company shall request that DTC, pursuant to the
applicable rules and operating procedures of DTC then in effect, transmit the Automatic Conversion Notice to the direct participants of DTC holding the Securities at such time. 

Upon delivery of the Automatic Conversion Notice, the Company shall deliver to the Trustee and the Paying Agent 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 and the Paying
Agent are each 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 Capital Adequacy Trigger Event Officers’ Certificate shall be conclusive and binding on the Trustee, the Paying Agent, the Holders and the Beneficial Owners. 

(c) Within ten (10) Business Days following the Conversion Date, the Company shall deliver a Conversion Shares Offer Notice. 

(d) The procedures set forth in this Section 2.15 are subject to change to reflect changes in DTC’s practices, and the Company may
make changes to the procedures set forth in this Section 2.15 to the extent reasonably necessary, in the opinion of the Company, to reflect such changes in DTC’s practices. 

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

(f) Notwithstanding anything to the contrary contained in the Indenture or the Securities, once the Company has delivered an Automatic
Conversion Notice following the occurrence of a Capital Adequacy Trigger Event (or following an Automatic Conversion (if sooner)), (i) subject to the right of Holders and Beneficial Owners pursuant to Section 4.03 in the event of a failure by
the Company to issue and deliver any Conversion Shares to the Conversion Shares Depository on the Conversion Date, the Holders and Beneficial Owners shall have no rights whatsoever under the Indenture or the Securities to instruct the Trustee or the
Paying Agent 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 2.15(f), 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 or unless the Trustee or the Paying Agent is
instructed in writing by the Company to act otherwise. 

  
 24 

 (g) Neither the Trustee nor the Paying Agent shall be liable with respect to (i) the
calculation or accuracy of the End-point 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 End-point CET1 Ratio calculations of a Capital Adequacy Trigger Event to DTC, the Holders or the Beneficial Owners or (iii) any aspect of the Company’s
decision to deliver an Automatic Conversion Notice or the related Automatic Conversion. 
 (h) Notwithstanding any other provision herein, by
its acquisition of the Securities, each Holder (which, for these purposes, includes each Beneficial Owner) (i) consents to all of the terms and conditions of the Securities, including (x) the occurrence of a Capital Adequacy Trigger Event
and any related Automatic Conversion following a Capital Adequacy Trigger Event and (y) the appointment of the Conversion Shares Depository (or to the relevant recipient pursuant to Section 2.15), the issuance of the Conversion Shares to
the Conversion Shares Depository (or to the relevant recipient pursuant to Section 2.15) and the potential sale of the Conversion Shares pursuant to a Conversion Shares Offer, (ii) acknowledges and agrees that effective upon, and following, a
Capital Adequacy Trigger Event, other than any amounts payable in the case of the Company’s winding-up or the appointment of an administrator for its administration pursuant to Section 5.01, no
Holder shall have any rights against the Company with respect to repayment of the principal amount of the Securities or payment of interest or any other amount on or in respect of such Securities, in each case that is not due and payable, which
liabilities of the Company shall be automatically released, (iii) acknowledges and agrees that events in, and related to, clause (i) may occur without any further action on the part of such Holder, the Trustee or the Paying Agent,
(iv) authorizes, directs and requests DTC and any direct participant in DTC or other intermediary through which it holds such Securities to take any and all necessary action, if required, to implement the Automatic Conversion without any
further action or direction on the part of such Holder, the Trustee or the Paying Agent and (v) 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. 

SECTION 2.16. Conversion Shares. 

(a) The number of Conversion Shares to be issued to the Conversion Shares Depository (or to the relevant recipient pursuant to
Section 2.15) on the Conversion Date shall equal the quotient obtained by dividing the (i) aggregate principal amount of the Securities then Outstanding immediately prior to the Automatic Conversion on the Conversion Date (the
“Outstanding Amount”) by (ii) the Conversion Price, rounded down, if necessary, to the nearest whole number of Conversion Shares. The number of Conversion Shares to be held by the Conversion Shares Depository for the benefit of
a Holder shall equal the product obtained by multiplying (i) the number of Conversion Shares thus calculated by (ii) the quotient obtained by dividing (x) the Tradable Amount held by such Holder on the Conversion Date by (y) the
Outstanding Amount, such product to be 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. 
 (b) Subject to Section 3.05 (including the conditions specified therein), 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 shall be issued by the Approved Entity to the Conversion Shares Depository instead of Conversion Shares with the same effect as if Conversion Shares
had been issued pursuant to Section 2.16(a). 

  
 25 

 SECTION 2.17. Conversion Shares Offer. 

(a) Following the occurrence of an Automatic Conversion, the Company, in its sole and absolute discretion, may elect in the Conversion Shares
Office Notice that the Conversion Shares Depository make an offer of all or some of the Conversion Shares to all or some of the Shareholders at a cash price per Conversion Share equal to the Conversion Shares Offer Price (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. 

(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 any interest in the Conversion Shares to the Conversion Shares Depository (or the relevant recipient pursuant to Section 2.15) in order for the Conversion Shares Depository (or the relevant recipient pursuant to
Section 2.15) to conduct the Conversion Shares Offer), including the fees of the Conversion Shares Offer Agent, if any. 
 (c) Upon
completion of the Conversion Shares Offer, the Company or the Conversion Shares Depository shall provide notice to the Holders of the composition of the Conversion Shares Offer Consideration (and the Cash Component thereof, if any) 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 and the Paying Agent directly and to the Holders, in the case of Global Securities, via DTC (or, if the Securities are definitive Securities, to the Holders at their addresses shown on the 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) 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) The Cash Component of any Conversion Shares Offer Consideration shall be payable by the
Conversion Shares Depository to the Holders and Beneficial Owners (or the custodian, nominee, broker or other representative thereof) of the Securities whether or not the Solvency Condition is satisfied. 

(e) If the Company elects, in its sole and absolute discretion, that a Conversion Shares Offer be conducted, each Holder (which, for these
purposes, includes each Beneficial Owner) by its acquisition of the Securities, shall (i) consent to (x) any Conversion Shares Offer and to the Conversion Shares Depository’s using the Conversion Shares to settle any Conversion Shares
Offer in accordance with the terms of the Securities, notwithstanding that such Conversion Shares are held by the Conversion Shares Depository on behalf of Holders and Beneficial Owners 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 agree that (x) the Company, the Conversion Shares Depository
(or the relevant recipient pursuant to Section 2.15) and the Conversion Shares Offer Agent, if any, may take any and all actions necessary to conduct the Conversion Shares Offer in accordance with the terms of the Securities, and (y) none
of the Company, the Trustee, the Paying Agent, 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).

(b) On the Suspension Date, the Company shall deliver an Automatic Conversion Settlement Request Notice. 

(c) 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 Offer Consideration, as applicable, unless such Holders or Beneficial Owners (or the custodian, nominee, broker or other representative thereof) deliver the applicable Automatic Conversion 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. 
 (d) With
respect to any Global Securities, the Automatic Conversion Settlement Notice must be given in accordance with the respective standard procedures of DTC (which may include, without limitation, delivery of the notice to the Conversion Shares
Depository by electronic means) and in a respective form acceptable to DTC and the Conversion Shares Depository. With respect to any definitive Securities, the Automatic Conversion Settlement Notice must be delivered to the specified office of the
Conversion Shares Depository together with the relevant Securities. 
 (e) Subject to satisfaction of the requirements and limitations set
forth in this Section 2.18 and provided that the Automatic Conversion Settlement Notice and the relevant Securities, if applicable, are delivered, the Conversion Shares Depository shall deliver the relevant Conversion Shares or
Conversion Shares Offer Consideration, as applicable, on the applicable Settlement Date to the Holder or Beneficial Owner (or custodian, nominee, broker or other representative thereof) having completed the relevant Automatic Conversion Settlement
Notice and in accordance with the instructions given in such Automatic Conversion Settlement Notice. 
 (f) Each Automatic Conversion
Settlement Notice shall be irrevocable. The Conversion Shares Depository shall determine, in its sole and absolute discretion, whether any Automatic Conversion 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 an Automatic Conversion Settlement Notice (and the relevant Securities, if applicable) the Conversion
Shares Depository shall be entitled to treat such Automatic Conversion Settlement Notice as null and void. 
 (g) Neither the Company, nor
any member of the HSBC Group, shall be liable for any taxes or duties (including, without limitation, any capital, stamp, issue and registration or transfer taxes or duties) arising on conversion or that may arise or be paid as a consequence of the
issue and delivery of Conversion Shares following an Automatic Conversion. The Holder or Beneficial Owner must pay any taxes or duties (including, without limitation, any capital, stamp, issue and registration and /or transfer taxes or duties)
arising on conversion in connection with the issue and delivery of Conversion Shares to the Conversion Shares Depository on behalf of such Holder or Beneficial Owner, and such Holder or 

  
 27 

 Beneficial Owner must pay all, if any, such taxes or duties arising by reference to any disposal or deemed
disposal of such Holder or Beneficial Owner’s Securities or interest therein. Any taxes or duties arising on delivery or transfer of Conversion Shares to a purchaser in any Conversion Shares Offer shall be payable by the relevant purchaser of
those Conversion Shares. 
 (h) The Conversion Shares and any Conversion Shares Component shall not be available for delivery (i) to, or
to a nominee for, Clearstream Luxembourg or Euroclear or any other person providing a clearance service within the meaning of Section 96 of the Finance Act 1986 of the United Kingdom or (ii) to a person, or nominee or agent for a person, whose
business is or includes issuing depository receipts within the meaning of Section 93 of the Finance Act 1986 of the United Kingdom, in each case at any time prior to the “abolition day” as defined in Section 111(1) of the Finance
Act 1990 of the United Kingdom, or, if earlier, such other time at which the Company, in its absolute discretion, determines that no charge under Section 67, 70, 93 or 96 of the Finance Act 1986 or any similar charge (under any successor
legislation) would arise as a result of such delivery or (iii) to the CREST account of such a person described in (i) or (ii). 

(i) The Company may make changes to the procedures set forth in this Section 2.18 to the extent such changes are reasonably necessary, in
the opinion of the Company, to effect the delivery of the Conversion Shares or Conversion Shares Offer Consideration, as applicable, to the Holders and Beneficial Owners. 

SECTION 2.19. Failure to Deliver an Automatic Conversion Settlement Notice. If any Holder or Beneficial Owner (or custodian, nominee,
broker or other representative thereof) fails to deliver an Automatic Conversion 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 Conversion Shares Offer Consideration, as applicable, until an Automatic Conversion Settlement Notice (and the
relevant Securities, if applicable) is so delivered; provided, however, that the relevant Securities shall be cancelled on the Final Cancellation Date, and any Holder or Beneficial Owner (or custodian, nominee, broker or other
representative thereof) delivering an Automatic Conversion Settlement Notice after the Notice Cut-off Date shall be required to provide evidence of its entitlement to the relevant Conversion Shares or
Conversion Shares Offer Consideration, as applicable, satisfactory to the Conversion Shares Depository in its sole and absolute discretion in order to receive delivery of such Conversion Shares or Conversion Shares Offer Consideration, as
applicable. The Company shall have no liability to any Holder or Beneficial Owner for any loss resulting from such Holder or Beneficial Owner’s failure to receive any Conversion Shares or 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 an Automatic Conversion Settlement Notice (and the relevant
Securities, if applicable) on a timely basis or at all. 
 SECTION 2.20. Agreement with Respect to the Exercise of the UK
Bail-in Power. 
 (a) By its acquisition of the Securities, each Holder (which, for these
purposes, includes each Beneficial Owner): 
 (i) acknowledges, accepts, consents and agrees, notwithstanding any other term
of the Securities, the Indenture or any other agreements, arrangements or understandings between the Company 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 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 Company’s or another Person’s 

  
 28 

 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 Securities or the Indenture; (iii) the cancellation of the Securities;
and/or (iv) the amendment or alteration of the redemption date of the Securities or amendment of the amount of interest payable on the Securities, or the Interest Payment Dates, including by suspending payment for a temporary period; and
(y) the variation of the terms of the Securities or the Indenture, if necessary, to give effect to the exercise of any UK Bail-in Power by the Relevant UK Resolution Authority; and 

(ii) consents to the exercise of any UK Bail-in Power as it may be imposed without any
prior notice by the Relevant UK Resolution Authority of its decision to exercise such power with respect to the Securities. 

(b) By its acquisition of the Securities, each Holder (which, for these purposes, includes each Beneficial Owner): 

(i) acknowledges and agrees that neither a Capital Adequacy Trigger Event, an Automatic Conversion, a reduction or
cancellation, in part or in full, of the Amounts Due (including pursuant to Sections 2.03 and 2.04), the conversion thereof into another security or obligation of the Company or another Person, as a result of the exercise of the UK Bail-in Power by the Relevant UK Resolution Authority with respect to the Securities, nor the exercise of the UK Bail-in Power by the Relevant UK Resolution Authority with
respect to the Securities shall give rise to a Default or an 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; 

(ii) 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 the UK Bail-in Power by the Relevant UK Resolution Authority with respect to the Securities; 

(iii) acknowledges and agrees that, upon the exercise of any UK Bail-in Power by the
Relevant UK Resolution Authority (a) the Trustee shall not be required to take any further directions from Holders under Section 5.12 of the Base Indenture and (b) none of the Base Indenture or this Seventh Supplemental Indenture
shall impose any duties upon the Trustee whatsoever with respect to the exercise of any UK Bail-in Power by the Relevant UK Resolution Authority; and 

(iv) shall be deemed to have authorized, directed and requested DTC and any direct participant in DTC or other intermediary
through which it holds such Securities to take any and all necessary action, if required, to implement the exercise of the UK 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, the Trustee or the Paying Agent. 
 (c) Upon the exercise of the UK Bail-in Power by the Relevant UK Resolution Authority with respect to the Securities, the Company shall provide a written notice to Holders through DTC as soon as practicable regarding such exercise of the UK Bail-in Power. The Company shall also deliver a copy of such notice to the Trustee for information purposes. 

(d) The exercise of the UK Bail-in Power by the Relevant UK Resolution Authority with respect to the
Securities shall not constitute a Winding-Up Event or a Non-Payment Event. 

  
 29 

 (e) In addition to the right to enter into supplemental indentures pursuant to Sections 9.01 and
9.02 of the Base Indenture, the Company 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 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. 

(f) Notwithstanding anything to the contrary in the Indenture, including Article 9 of the Base Indenture, the Company hereby agrees that it
shall not amend Section 2.20(a) without the prior consent of the Relevant Regulator. 
 (g) Notwithstanding Section 2.20(b)(iii),
if, following the completion of the exercise of the UK Bail-in Power by the Relevant UK Resolution Authority, any 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 Securities), then the Trustee’s duties under the Indenture shall remain applicable with respect to the Securities following such
completion to the extent the Company 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 in the event the Securities remain Outstanding following the completion of the exercise of the UK Bail-in Power. 

(h) For the avoidance of doubt, the potential conversion of the Securities into shares, other securities or other obligations in connection
with the exercise of any UK Bail-in Power by the Relevant UK Resolution Authority is separate and distinct from an Automatic Conversion following a Capital Adequacy Trigger Event. 

SECTION 2.21. Notice via DTC. If notice is given by the Company via DTC in accordance with the terms of the Securities and the
Indenture, the Company shall request that DTC, pursuant to the applicable rules and operating procedures of DTC then in effect, transmit such notice to the direct participants of DTC holding the Securities at such time. Moreover, any notice by DTC
to participating institutions and by these participants to street name holders of beneficial interests in the Securities shall be made according to arrangements among them and may be subject to statutory or regulatory requirements. Any such notice
given by the Company to DTC also shall be sent directly to the Trustee and the Paying Agent for informational purposes. 
 SECTION 2.22.
Records Adjustment. Upon receipt of any notice given pursuant to the Indenture, to the extent applicable, the Company, the Trustee and the Agent shall adjust their records to reflect any cancellation or deemed cancellation of any interest and
any changes to the aggregate principal amount of the Securities then Outstanding, including due to any exercise of the UK Bail-in Power by the Relevant UK Resolution Authority, any Automatic Conversion or any
redemption pursuant to Sections 2.08, 2.09 and 2.10. 
 ARTICLE III 

ANTI-DILUTION 
 SECTION
3.01. Adjustment of Conversion Price and Conversion Shares Offer Price. Upon the occurrence of any of the events described below, the Conversion Price and the Conversion Shares Offer Price, as applicable, shall be adjusted as follows: 

  
 30 

 (a) If and whenever there is a consolidation, reclassification, redesignation or subdivision in
relation to the Ordinary Shares which alters the number of Ordinary Shares in issue, each Price shall be adjusted by multiplying the relevant Price in effect immediately prior to such consolidation, reclassification or subdivision by the following
fraction: 
 A 
 B 

where: 
  

	 	A	is the aggregate number of Ordinary Shares in issue immediately before such consolidation, reclassification, redesignation or subdivision, as the case may be; and 

 

	 	B	is the aggregate number of Ordinary Shares in issue immediately after, and as a result of, such consolidation, reclassification, redesignation or subdivision, as the case may be. 

Such adjustment shall become effective on the date the consolidation, reclassification, redesignation or subdivision, as the case may be, takes
effect. 
 (b) If and whenever the Company issues Ordinary Shares to Shareholders credited as fully paid 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 Shareholders would or could otherwise
have elected to receive, (2) where Shareholders may elect to receive a Cash Dividend in lieu of such Ordinary Shares or (3) where any such Ordinary Shares are or are expected 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 Shareholders, whether at their election or otherwise), each Price shall be adjusted by multiplying the relevant Price in effect immediately prior to such issue by the following
fraction: 
 A 
 B 

where: 
  

	 	A	is the aggregate number of Ordinary Shares in issue immediately before such issue; and 

  

	 	B	is the aggregate number of Ordinary Shares in issue immediately after such issue. Such adjustment shall become effective on the date of issue of such Ordinary Shares. 

(c) If and whenever the Company issues Ordinary Shares to Shareholders as a class by way of rights, or the Company or any member of the HSBC
Group or (at the direction or request or pursuant to arrangements with the Company or any member of the HSBC Group) any other company, person or entity issues or grants to Shareholders as a class by way of rights, any options, warrants or other
rights to subscribe for or purchase the Ordinary Shares, or any securities which by their terms of issue carry (directly or indirectly) rights of conversion into, or exchange or subscription for, any Ordinary Shares (or grants any such rights in
respect of existing securities so issued), in each case at a price per Ordinary Share which is less than 95% of the Current Market Price on the Effective Date, each Price shall be adjusted by multiplying the relevant Price in effect immediately
prior to the Effective Date by the following fraction: 
 A + B 

A + C 

  
 31 

 where: 
  

	 	A	is the aggregate number of Ordinary Shares in issue on the Effective Date; 

  

	 	B	is the number of Ordinary Shares which the aggregate consideration (if any) receivable for the Ordinary Shares issued by way of rights, or for the securities issued by way of rights, or for the options or warrants or
other rights issued by way of rights and for the total number of the Ordinary Shares deliverable on the exercise thereof, would purchase at such Current Market Price on the Effective Date; and 

 

	 	C	is the number of Ordinary Shares to be issued or, as the case may be, the maximum number of Ordinary Shares which may be issued upon exercise of such options, warrants or rights calculated as of the date of issue of
such options, warrants or rights or upon conversion or exchange or exercise of rights of subscription or purchase in respect thereof at the initial conversion, exchange, subscription or purchase price or rate; provided that if, on the
Effective Date, such number of Ordinary Shares is to be determined by reference to the application of a formula or other variable feature or the occurrence of any event at some subsequent time, then “C” shall be determined by the
application of such formula or variable feature or as if the relevant event occurs or had occurred as of the Effective Date and as if such conversion, exchange, subscription, purchase or acquisition had taken place on the Effective Date.

 Such adjustment shall become effective on the Effective Date. 

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

	 	(1)	the aggregate consideration receivable or price for Ordinary Shares issued for cash shall be the amount of such cash; 

  

	 	(2)	(x) the aggregate consideration receivable or price for Ordinary Shares to be issued or otherwise made available upon the conversion or exchange of any securities shall be deemed to be the consideration or price
received or receivable for any such securities and (y) the aggregate consideration receivable or price for Ordinary Shares to be issued or otherwise made available upon the exercise of rights of subscription attached to any securities or upon
the exercise of any options, warrants or rights shall be deemed to be that part (which may be the whole) of the consideration or price received or receivable for such securities or, as the case may be, for such options, warrants or rights which are
attributed by the Company to such rights of subscription or, as the case may be, such options, warrants or rights or, if no part of such consideration or price is so attributed, the Fair Market Value of such rights of subscription or, as the case
may be, such options, warrants or rights as of the relevant Effective Date, plus in the case of each of (x) and (y), the additional minimum consideration receivable or price (if any) upon the conversion or exchange of such securities, or upon
the exercise of such rights or subscription attached thereto or, as the case may be, upon exercise of such options, warrants or rights and (z) the consideration receivable or price per Ordinary Share upon the conversion or exchange of, or upon
the exercise of such rights of subscription attached to, such securities or, as the case may be, upon the exercise of such options, warrants or rights shall be the aggregate consideration or price referred to in (x) or (y) (as the case may be)
divided by the number of Ordinary Shares to be issued upon such conversion or exchange or exercise at the initial conversion, exchange or subscription price or rate; 

  
 32 

	 	(3)	if the consideration or price determined pursuant to (1) or (2) (or any component thereof) is expressed in a currency other than dollars, it shall be converted into dollars at the Prevailing Rate on the relevant
Effective Date (in the case of (1) above) or the relevant date of first public announcement (in the case of (2) above); 

  

	 	(4)	in determining the consideration or price pursuant to the above, no deduction shall be made for any commissions or fees (howsoever described) or any expenses paid or incurred for any underwriting, placing or management
of the issue of the relevant Ordinary Shares or securities or options, warrants or rights, or otherwise in connection therewith; and 

  

	 	(5)	the consideration or price shall be determined as provided above on the basis of the consideration or price received, receivable, paid or payable, regardless of whether all or part thereof is received, receivable, paid
or payable by or to the Company or another entity. 

 (d) If and whenever the Company pays any Extraordinary Dividend to the
Ordinary Shareholders as a class, each Price shall be adjusted by multiplying the relevant Price in effect immediately prior to the Effective Date by the following fraction: 

A – B 

   A 
 where: 

 

	 	A	is the Current Market Price of one Ordinary Share on the Effective Date; and 

  

	 	B	is the portion of the aggregate Extraordinary Dividend attributable to one Ordinary Share, with such portion being determined by dividing the aggregate Extraordinary Dividend by the number of Ordinary Shares entitled to
receive the relevant Extraordinary Dividend. If the Extraordinary Dividend is expressed in a currency other than dollars, it shall be converted into dollars at the Prevailing Rate on the relevant Effective Date. 

Such adjustment shall become effective on the Effective Date. 
  

	 	(e)	Notwithstanding provisions of Sections 3.01(a) through (d): 

 (i) where the
events or circumstances giving rise to any adjustment pursuant to this Section 3.01 have already resulted or shall result in an adjustment to the Prices 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 shall give rise to an adjustment to the Prices or where more than one event that gives rise to an adjustment to the Prices occurs within such a short period of time that, in the Company’s
opinion, 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 by an Independent Financial Adviser to
be in its opinion appropriate to give the intended result; 

  
 33 

 (ii) such modification shall be made to the operation of this Section 3.01
as may be determined by an Independent Financial Adviser to be in its opinion appropriate (x) to ensure that an adjustment to the Prices or the economic effect thereof shall not be taken into account more than once, (y) to ensure that the
economic effect of an Extraordinary Dividend is not taken into account more than once and (z) to reflect a redenomination of the issued Ordinary Shares for the time being into a new currency; 

(iii) for the avoidance of doubt, the occurrence of any other event in respect of the Ordinary Shares that is not an applicable
Adjustment Event in relation to the Securities or the conversion of the Securities into the Ordinary Shares pursuant to this Section 3.01 shall not result in an adjustment of the Prices; and 

(iv) No adjustment shall be made to the Prices where the Ordinary Shares or other securities (including rights, warrants and
options) are issued, offered, exercised, allotted, purchased, appropriated, modified or granted to, or for the benefit of, employees or former employees (including directors holding or formerly holding executive office or the personal service
company of any such person) or their spouses or relatives, in each case, of the Company or any company in the HSBC Group or any associated company or to a trustee or trustees to be held for the benefit of any such person, in any such case pursuant
to any share or option scheme. 
 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 sub-division as described in Section 3.01(a), 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 3.01(b) through (d), but before the relevant adjustment to the Prices becomes effective under such Section.

 SECTION 3.03. Decision of an Independent Financial Adviser. If any doubt shall arise as to whether an adjustment should be made to
either Price or as to the appropriate adjustment to such Prices, 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, the Paying Agent 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 and the Conversion Shares Offer Price. 

(a) On any adjustment, if a resultant Price has more decimal places than the initial Price, it shall be rounded to the same number of decimal
places as the initial Price. No adjustment shall be made to a Price where such adjustment (rounded down if applicable) would be less than 1% of such Price then in effect. Any adjustment not required to be made, and/or any amount by which a 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 Prices shall be given by the Company
to Holders via DTC (or, if the Securities are definitive Securities, via the Trustee) promptly after the determination thereof. 
 (c) The
Prices shall not in any event be reduced to below the nominal value of the Ordinary Shares. The Company hereby undertakes that it shall not take any action, and shall procure that no action is taken, that would otherwise result in an adjustment to
the Prices to below such nominal value. 

  
 34 

 SECTION 3.05. Qualifying Takeover Event. 

(a) Within ten (10) Business Days following the occurrence of a Takeover Event, the Company shall deliver a Takeover Event Notice. 

(b) If the Takeover Event is a Qualifying Takeover Event, the Securities will, where the Conversion Date falls on or after the QTE Effective
Date, be converted into or exchanged for Approved Entity Shares, mutatis mutandis as provided under Section 2.15, at a Conversion Price that shall initially be the New Conversion Price, which may be higher or lower than the Conversion
Price. In addition, the Company shall retain the right to elect in the Conversion Shares Offer Notice that the Conversion Shares Depository make a Conversion Shares Offer at the New Conversion Shares Offer Price. 

(c) The New Conversion Price and the New Conversion Shares Offer Price shall be subject to adjustment in the circumstances provided for under
Section 3.01 (if necessary with such modifications and amendments as an Independent Financial Adviser shall determine to be appropriate), and the Company shall give notice to the Holders of the New Conversion Price and the New Conversion Shares
Offer Price and of any such modifications and amendments thereafter. 
 (d) In the case of a Qualifying Takeover Event 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 and conditions 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 2.15, at the New Conversion Price. 
 (e) For the avoidance of doubt, if for
any reason (including, without limitation, because the Acquirer is a Governmental Entity), a Takeover Event fails to be Qualifying Takeover Event, there shall not be 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. From and after the QTE Effective Date, the Company shall no longer have any obligation to deliver Ordinary Shares or any Approved Entity Shares, which shall be the
obligation of the Approved Entity pursuant to the terms of the agreements or arrangements with the Trustee.

Paying Agent shall notify the Trustee and, if such failure continues for fourteen (14) calendar days, the Trustee may provide a written notice of such failure to the Company. If within a period of fourteen (14) calendar 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 in accordance with the Indenture, 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 Section 2.03 or 2.04, the Company cancels any interest payment in respect of
any Interest Payment Date or if such interest payment is deemed to have been 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 shall occur or be deemed to have occurred as a result of such cancellation or deemed cancellation (in each case, in whole or in part). 

SECTION 4.03. Limited Remedies for Breach of Obligations (Other than Non-Payment). In addition
to the remedies for a Non-Payment Event provided in Section 4.02, the Trustee may without further notice institute such proceedings against the Company as it 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 payment of any principal or interest, including Additional
Amounts) (such obligation, a “Performance Obligation”); provided the sole and exclusive remedy that the Trustee (acting on behalf of the Holders) and/or the Holders may seek under the Securities and the Indenture is
specific performance under the laws of the State of New York; provided further that to the extent any judgment or other award given in such proceedings requires the payment of money by the Company, whether by way of damages or otherwise (a
“Monetary Judgment”), the Trustee (acting on behalf of the Holders) and/or the Holders may not enforce, and shall not be entitled to enforce, or otherwise claim such Monetary Judgment against the Company, except by proving such
Monetary Judgment in the winding-up or administration of the Company. For the avoidance of doubt, any breach by the Company of any Performance Obligation shall not confer upon the Trustee (acting on behalf of
the Holders) and/or the Holders any claim other than specific performance and the Company shall not be obliged to pay any sum or sums, in cash or otherwise (including damages), as a consequence of the institution of any such proceedings, except
where a Holder proves any Monetary Judgment in the Company’s winding-up or administration. 

By its acquisition of the Securities, each Holder (which, for these purposes includes each Beneficial Owner) of the Securities acknowledges
and agrees (i) that the sole and exclusive remedy that such Holder and/or the Trustee (acting on their behalf) may seek under the Securities and the Indenture for a breach by the Company of a Performance Obligation is specific performance under
the laws of the State of New York, (ii) such Holder shall not (and waive any right to) seek, and shall not (and waive any right to) direct the Trustee (acting on their behalf) to seek, any other remedy against the Company in

  
 36 

 respect of any breach by the Company of a Performance Obligation, (iii) such Holder shall not (and waive any
right to) enforce, and shall not be entitled to enforce (and waive any such entitlement), or otherwise claim (and waive any other right to claim) a Monetary Judgment against the Company, except by proving such Monetary Judgment in the Company’s
winding-up or administration and (iv) to the extent permitted by the Trust Indenture Act, such Holder waives any and all claims, in law and/or in equity, against the Trustee for, agree not to initiate a
suit against the Trustee in respect of, and agree that the Trustee shall not be liable for, any action that the Trustee takes, or abstains from taking, in connection with such Holder’s right to enforce a Performance Obligation in accordance
with the Indenture or the Securities. 
 SECTION 4.04. No Other Remedies and Other Terms. 

(a) Other than the limited remedies specified in this Article IV, and subject to clause (c) below, no remedy against the Company shall be
available to the Trustee (acting on behalf of the Holders) and to the Holders and Beneficial Owners, whether for the recovery of amounts owing in respect of such 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 5.06 of the Base Indenture expressly survive any Default and are not subject to the subordination
provisions of Section 5.01 hereof. 
 (b) In the case of a Default under the Securities, 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 (i) upon the occurrence of a Winding-Up Event that occurs before the Conversion Date or (ii) upon the occurrence of a Non-Payment Event or
(iii) upon a breach by the Company of a Performance Obligation. For purposes of the Base Indenture, “Event of Default” shall mean “Default” as defined in this Seventh Supplemental Indenture, except that the term
“Event of Default” as used in Section 3.05(c)(ii) of the Base Indenture and Article 8 of the Base Indenture shall mean “Winding-Up Event.” 

(c) Subject to such provisions for the indemnification of the Trustee, and subject to certain exceptions, the Holder or Holders of a majority
in aggregate principal amount of the Securities then Outstanding shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee
with respect to the Securities. However, the Trustee may refuse to follow any direction that is in conflict with any rule of law or the Indenture or is unjustly prejudicial to any Holder not taking part in the direction. The Trustee may take any
other action that it deems proper which is not inconsistent with that direction. 
 (d) Neither a Capital Adequacy Trigger Event, an
Automatic Conversion, a cancellation or deemed cancellation of interest (in each case, in whole or in part) in accordance with the terms of the Indenture and the Securities nor the exercise of the UK Bail-in
Power by the Relevant UK Resolution Authority with respect to the Securities shall be stated to be an Event of Default or a Default. 
 (e)
Notwithstanding the limitations on remedies specified under this Article IV, (i) 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 under the provisions of the Indenture, and (ii) nothing shall impair the right of a Holder or Beneficial Owner 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 (i) and (ii) 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 5.01 hereof. 

  
 37 

 SECTION 4.05. Waiver of Past Defaults. 

(a) Holders of not less than a majority in aggregate principal amount of the Securities then Outstanding may on behalf of the Holders of all of
the Securities waive any past Default that results from a breach by the Company of a Performance Obligation; provided that (i) a Default in respect of a Performance Obligation, the modification or amendment of which would require the
consent of each Holder affected by it or (ii) any past Default that results from a Winding-Up Event or a Non-Payment Event, in either case, will require the waiver
of each Holder affected by such Default. 
 (b) Upon the occurrence of any waiver permitted by clause (a) above, such Default shall
cease to exist, and any Default with respect to any series arising therefrom shall be deemed to have been cured and not to have occurred for every purpose of the Base Indenture, but no such waiver shall extend to any subsequent or other Default or
impair any right consequent thereon. 
 ARTICLE V 

SUBORDINATION 
 SECTION
5.01. Securities Subordinate to Claims of Senior Creditors. With respect to the Securities only, this Section 5.01 hereby amends Section 12.01 of the Base Indenture in its entirety, and references in the Base Indenture to Article
Twelve and Section 12.01 thereof shall be to such Article and Section as amended by this Section 5.01. 
 (a) The Securities shall
constitute the Company’s direct, unsecured and subordinated obligations, ranking equally without any preference among themselves. The rights and claims of the Holders and Beneficial Owners in respect of or arising from the Securities shall be
subordinated to the claims of Senior Creditors. 
 (b) If (x) 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 of the Company, the terms of
which reorganization, reconstruction or amalgamation (i) have previously been approved in writing by a majority of the Holders and (ii) do not provide that the Securities shall thereby become redeemable or repayable in accordance with the
terms of the Securities); or (y) following the appointment of an administrator for the Company’s administration, the administrator declares, or gives notice that it intends to declare and distribute, a dividend, then 

(i) if such events specified in (x) or (y) 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 if, on the day prior to the commencement of such
winding-up or such administration and thereafter, such Holder were the holder of the most senior class of preference shares in the Company’s capital, having an equal right to a return of assets in such 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
of assets in such 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 Company’s capital, but ranking junior to the claims
of Senior Creditors, and on the assumption that the amount that such Holder was entitled to receive in respect of such senior preference shares, on a return of assets in such winding-up or such administration,
were an amount equal to the principal amount of the relevant Security, together with any accrued but unpaid interest thereon (to the extent not cancelled or deemed to have been cancelled) and any Monetary Judgment (if payable); and 

  
 38 

 (ii) if such events specified in (x) or (y) above occur on or after the date
on which a Capital Adequacy Trigger Event occurs but prior to the Conversion Date, 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 on a return of assets in such winding-up or such administration if the Conversion Date in respect of an Automatic Conversion had occurred immediately prior to the occurrence of such events specified in
(x) or (y) above (and as a result, such Holder were the holder of such number of Ordinary Shares as such Holder would have been entitled to receive on the Conversion Date, ignoring for these purposes the Company’s right to elect to make a
Conversion Shares Offer). 
 (c) Other than in the event of a winding-up or administration of the
Company as described in clause (b) above, 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, 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 (i) it is able to pay its debts owed to Senior Creditors as they fall due and (ii) the Balance Sheet
Condition has been met. A certificate by the Auditors as to whether or not the Solvency Condition is met, on the basis of the information provided to the Auditors by the Company, will, in the absence of manifest error, 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 (i) who are unsubordinated creditors; (ii) whose claims are, or are expressed to be, subordinated to the claims of the Company’s unsubordinated creditors but not further or otherwise;
or (iii) whose claims are, or are expressed to be, junior to the claims of the Company’s other creditors, 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 or Beneficial Owners in a winding-up occurring prior to a Capital Adequacy Trigger Event. For the avoidance of doubt, holders of any of the Company’s existing or
future Tier 2 capital instruments shall be Senior Creditors. 
 The “Balance Sheet Condition” shall be satisfied in
relation to the Company if the value of the Assets is at least equal to the value of the Liabilities. For these purposes (i) “Assets” mean the Company’s unconsolidated gross assets as shown in the Company’s most recent
published audited balance sheet, as adjusted for subsequent events in such manner as the Auditors may determine and (ii) “Liabilities” means the Company’s unconsolidated gross liabilities, as shown in the Company’s most
recent published audited balance sheet, as adjusted for subsequent events in such manner as the Auditors may determine and for these purposes excluding (without double counting) any indebtedness that shall not constitute 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 UK 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.

 ARTICLE VI 

AMENDMENTS TO THE BASE INDENTURE APPLICABLE TO ALL SERIES OF 

SECURITIES 
 SECTION 6.01.
Definitions. Article 1 of the Base Indenture is amended by amending and restating the definition of “FATCA” in Section 1.01 in its entirety, which shall read as follows: 

“FATCA” means (i) sections 1471 to 1474 of the Code or any associated regulations or other official guidance;
(ii) any treaty, law, regulation or other official guidance enacted in any other jurisdiction, or relating to an intergovernmental agreement between the United States and any other jurisdiction, which (in either case) facilitates the
implementation of clause (i); or (iii) any agreement pursuant to the implementation of clauses (i) or (ii) with the US Internal Revenue Service, the US government or any governmental or taxation authority in any other jurisdiction. 

SECTION 6.02. Additional Amounts. Article 10 of the Base Indenture is amended by amending and restating Section 10.04(a) of the
Base Indenture in its entirety, which shall read as follows: 
 (a) All payments made under or with respect to the Securities
shall be paid without deduction or withholding for, or on account of, any and all present and future taxes, levies, imposts, duties, charges, fees, deductions or withholdings whatsoever imposed, levied, collected, withheld or assessed by or on
behalf of the UK (or any political subdivision or taxing authority thereof or therein having the power to tax) (each a “Taxing Jurisdiction”) unless required by law. If such deduction or withholding will at any time be required by
the law of the Taxing Jurisdiction, the Company shall pay such additional amounts in respect of any payments of interest on the Securities (but not, for the avoidance of doubt, in respect of the payment of principal in respect of the Securities)
(“Additional Amounts”) as may be necessary so that the net amounts (including Additional Amounts) paid to the Holders, after such deduction or withholding, shall be equal to the respective amounts of interest which the Holders would
have been entitled to receive in respect of the Securities in the absence of such deduction or withholding; provided that the foregoing will not apply to any such tax, levy, impost, duty, charge, fee, deduction or withholding which:
(i) would not be payable or due but for the fact that the Holder or Beneficial Owner is domiciled in, or is a national or resident of, or engaging in business or maintaining a permanent establishment or being physically present in, the Taxing
Jurisdiction, or otherwise has some connection or former connection with the Taxing Jurisdiction other than the holding or ownership of a Security, or the collection of principal or interest payments on, or the enforcement of, a Security;
(ii) would not be payable or due but for the fact that the certificate representing the relevant Securities (x) is presented for payment in the Taxing Jurisdiction or (y) is 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 would have been entitled to such Additional Amount on presenting the same for payment at the close of such thirty (30) day period;
(iii) would not have been imposed if presentation for payment of the certificate representing the relevant Securities had been made to a paying agent other than the paying agent to which the presentation was made; (iv) is imposed in
respect of a Holder that is not the sole Beneficial Owner of the principal or the interest, or a portion of either, or that is a fiduciary or partnership, but only to the extent that a beneficiary or settlor with respect to the fiduciary, a
beneficial owner or member of the partnership would not have been entitled to the payment of an Additional Amount had the beneficiary, settlor, beneficial owner or member received directly its beneficial or distributive share of the payment;
(v) is imposed because of the failure to comply by the Holder or the Beneficial Owner or the Beneficial Owner of any payment on such Securities with a request from the Company addressed to the Holder or the Beneficial 

  
 40 

 Owner, including a written request from the Company related to a claim for relief under any
applicable double tax treaty (x) to provide information concerning the nationality, residence, identity or connection with a taxing jurisdiction of the Holder or the Beneficial Owner or (y) to make any declaration or other similar claim to
satisfy any information or reporting requirement, if the information or declaration is required or imposed by a statute, treaty, regulation, ruling or administrative practice of the Taxing Jurisdiction as a precondition to exemption from withholding
or deduction of all or part of the tax, duty, assessment or other governmental charge; (vi) is imposed in respect of any estate, inheritance, gift, sale, transfer, personal property, wealth or similar tax, duty assessment or other governmental
charge; or (vii) is imposed in respect of any combination of the above items. 
 Whenever in this Indenture there is
mentioned, in any context, the payment of any interest, if any, on or in respect of any Security, such mention shall be deemed to include mention of the payment of Additional Amounts provided for in this Section to the extent that, in such 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. 
 ARTICLE VII

HSBC Holdings plc 
 $[•] 

6.500% Perpetual Subordinated Contingent Convertible Securities 

(Callable March 23, 2028 and Every Five Years Thereafter) 

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 under and governed by the Indenture, dated as of August 1, 2014 (the “Base Indenture”), as supplemented by the Seventh Supplemental
Indenture, dated as of March 23, 2018 (the “Seventh Supplemental Indenture” and, together with the Base Indenture, the “Indenture”). 

HSBC Holdings 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 to Cede & Co., or registered assigns, the principal sum of $ [•] ([•]), 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
and shall not be redeemable except as provided in this Security and Sections 2.08, 2.09 and 2.10 of the Seventh Supplemental Indenture. 

From (and including) the Issue Date to (but excluding) March 23, 2028, the interest rate on the Securities shall be 6.500% per annum.
From (and including) each Reset Date to (but excluding) the next following Reset Date, the applicable per annum interest rate shall be equal to the sum of the applicable Mid-Market Swap Rate on the Reset
Determination Date and 3.606%. Subject to the provisions on the reverse of this Security relating to cancellation and deemed cancellation of interest and to Sections 2.03 and 2.04 of the Seventh Supplemental Indenture, interest, if any, shall be
payable in two equal semi-annual installments in arrear on March 23 and September 23 of each year (each, an “Interest Payment Date”); provided that if such 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. Subject to the provisions on the reverse of this Security relating to cancellation and deemed
cancellation of interest and to Sections 2.03 and 2.04 of the Seventh Supplemental Indenture, interest on the Securities, if any, shall be computed and payable in arrear and on the basis of a year of 360 days consisting of twelve (12) months of
thirty (30) days each and, in the case of an incomplete month, the actual number of days elapsed. The first date on which interest may be paid shall be September 23, 2018, for the period commencing on (and including) the Issue Date and
ending on (but excluding) September 23, 2018. If a date of redemption is not a Business Day, the Company may pay interest (if any) together with the principal on the next succeeding Business Day; provided that interest shall not accrue
during the period from and after the date of redemption. 
 The “Mid-Market Swap
Rate” is the Mid-Market Swap Rate Quotation that appears on Bloomberg page “ISDA 01” (or such other page as may replace such page on Bloomberg or such other information service, in each case, as may be nominated by the person
providing or sponsoring the information appearing on such page for purposes of displaying comparable rates) (the “Relevant Screen Page”) as of approximately 11.00 a.m. (New York time) on the relevant Reset Determination Date,
all as determined by the Calculation Agent; provided, however, that if no such rate appears on the Relevant Screen Page for a five-year term, then the Mid-Market Swap Rate shall be determined
through the use of straight-line interpolation by reference to two rates, one of which shall be determined in accordance with the above provisions, but as if the relevant Reset Period were the period of time for which rates are available next
shorter than the length of the actual Reset Period and the other of which shall be determined in accordance with the above provisions, but as if the relevant Reset Period were the period 

  
 A-2 

 of time for which rates are available next longer than the length of the actual Reset Period; provided
further that if on any Reset Determination Date the Relevant Screen Page is not available or the Mid-Market Swap Rate does not appear on the Relevant Screen Page, the Calculation Agent shall request the
principal office in New York of the Reference Banks to provide it with its Mid-Market Swap Rate Quotation as of approximately 11.00 a.m. (New York time) on the relevant Reset Determination Date. If two or more
of the Reference Banks provide the Calculation Agent with Mid-Market Swap Rate Quotations, the interest rate for the relevant Reset Period shall be the sum of 3.606% and the arithmetic mean (rounded, if necessary, to the nearest 0.001% (0.0005%
being rounded upwards)) of the relevant Mid-Market Swap Rate Quotations, as determined by the Calculation Agent. If only one or none of the Reference Banks provides the Calculation Agent with a Mid-Market Swap Rate Quotation, the interest shall be determined to be the rate of interest as of the last preceding Reset Date or, in the case of the initial Reset Determination Date, 6.500%. 

“Mid-Market Swap Rate Quotation” means a quotation (expressed as a percentage rate per annum) for the mean of the bid and
offered rates for the fixed leg payable semi-annually (calculated on the basis of twelve 30-day months or, in the case of an incomplete month, the actual number of days elapsed, in each case assuming a 360-day year) of a fixed-for-floating interest rate swap transaction in dollars which transaction (i) has a five-year term
commencing on the relevant Reset Date, (ii) is in an amount that is representative for a single transaction in the dollar swap rate market at 11.00 a.m. (New York time) with an acknowledged dealer of good credit in the swap market and
(iii) has a floating leg based on six-month LIBOR (calculated on the basis of twelve 30-day months or, in the case of an incomplete month, the actual number of days
elapsed, in each case assuming a 360-day year); provided that if (a) the Company determines that LIBOR has ceased to be calculated or administered and (b) the Independent Financial Adviser,
or, if the Company is unable to appoint the Independent Financial Adviser, the Company (acting in good faith and a commercially reasonable manner), determines that another rate has replaced LIBOR in customary market usage for setting rates
comparable to the Mid-Market Swap Rate (the “ Alternative Base Rate”), then the Mid-Market Swap Rate Quotation shall be the quotation of the mean of bid
and offered rates determined as provided above but as if the reference to LIBOR was a reference to the Alternative Base Rate and with such adjustments (if any) as may in the Company’s determination (after consultation with the Independent
Financial Adviser, if appointed as provided above) be necessary to take account of any adjustment factor to make such rates comparable to rates quoted on the basis of LIBOR; provided further that if the determination of the Alternative Base
Rate occurs less than five (5) Business Days prior to the relevant Reset Determination Date, the rate of interest shall be as of the last preceding Reset Date or, in the case of the initial Reset Determination Date, 6.500%. 

“Reset Date” means March 23, 2028 and each fifth (5th) anniversary
date thereafter. If any Reset Date is not a Business Day, the Reset Date shall occur on the next succeeding Business Day. For the avoidance of doubt, if the Reset Date is not a Business Day and accordingly the Reset Date occurs on the next Business
Day (the “Adjusted Reset Date”), then the equal semi-annual payment of interest (if paid) on the next Interest Payment Date shall reflect interest for the entire interest period (including any portion of such interest period
occurring between the originally scheduled Reset Date and the Adjusted Reset Date) at the interest rate determined based on the Adjusted Reset Date, and not at the interest rate that applied to the immediately preceding semi-annual interest period.
In addition and for the avoidance of doubt, in connection with any optional redemption of this Security pursuant to the terms of this Security and Section 2.08 of the Seventh Supplemental Indenture, if the Reset Date is not a Business Day, as
described above, the Company may pay the interest (if any) together with the principal on the Adjusted Reset Date, but interest on that payment shall not accrue during the period from and after the last Interest Payment Date. 

  
 A-3 

 By its acquisition of the Securities, each Holder (which, for these purposes includes each
Beneficial Owner) (i) waives any and all claims, in law and/or in equity, against the Trustee and the Agent for, agrees not to initiate a suit against the Trustee and the Agent in respect of, and agrees that neither the Trustee nor the Agent
shall be liable for, the determination of or the failure to determine any Alternative Base Rate (including any adjustments thereto) and any losses suffered in connection therewith, and (ii) agrees that neither the Trustee nor the Agent shall
have any obligation to determine any Alternative Base Rate (including any adjustments thereto), including in the event of any failure by the Company to determine any Alternative Base Rate. 

In addition to any other restrictions on payments of principal and interest contained in this Security and the Seventh Supplemental 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 UK Bail-in Power by the Relevant UK Resolution Authority
unless, at the time such repayment or payment, respectively, is scheduled to become due, 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 HSBC Group. 
 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. For the avoidance of doubt, 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 to
have been cancelled (in each case, in whole or in part) in accordance with the provisions of this Security and as set forth in Sections 2.03(a) and 2.04 of the Seventh Supplemental Indenture, and any interest cancelled or deemed to have been
cancelled (in each case, in whole or in part) pursuant to such Sections shall not be due and shall not accumulate or be payable at any time thereafter, and Holders and Beneficial Owners shall have no rights thereto or to receive any additional
interest or compensation as a result of such cancellation or deemed cancellation. 
 Without prejudice to the foregoing paragraph or the
provisions of Section 2.03 of the Seventh Supplemental Indenture or the prohibition contained in Article 141(2) of CRD (and any implementation of such provision in the United Kingdom or, as the case may be, any succeeding provision amending or
replacing such Article or any such implementing provision) on the making of payments on the Securities before the Maximum Distributable Amount has been calculated, and subject to the extent permitted by the immediately following sentence in respect
of partial interest payments in respect of this Security, the Company shall not make an interest payment in respect of this Security 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 (i) the amount of Relevant Distributions exceeds the amount of Distributable Items as of such Interest Payment Date; (ii) the aggregate of (x) the interest amount payable
in respect of the Securities and (y) the amounts of any distributions of the kind referred to in Article 141(2) of CRD (and any implementation of such provision in the United Kingdom or, as the case may be, 

  
 A-4 

 any succeeding provision amending or replacing such Article or any such implementing provision) exceeds the
Maximum Distributable Amount (if any) applicable to the Company as of such Interest Payment Date; (iii) the Solvency Condition is not satisfied in respect of such interest payment or the Relevant Regulator orders the Company to cancel (in whole
or in part) the interest otherwise payable on such Interest Payment Date. 
 The Company may, in its sole discretion, elect to make a
partial interest payment in respect of this Security on any Interest Payment Date, only to the extent that such partial interest payment may be made without breaching the restriction in the immediately preceding sentence. 

By its acquisition of the Securities, each Holder (which, for these purposes, includes each Beneficial Owner) acknowledges and agrees that
(a) 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 to have been cancelled (in whole or in part), including as a result of the Distributable Items or the Maximum Distributable Amount being exceeded, failing to satisfy the Solvency
Condition under Section 2.04 or an order from the Relevant Regulator; and (b) a cancellation or deemed cancellation of interest (in each case, in whole or in part) in accordance with the terms of the Indenture and this Security shall not
constitute a default in payment or otherwise under the terms of this Security or the Indenture. 
 Payments of principal of and interest, if
any, on this Security shall be made in dollars and such payments on this Security shall be made through one or more Paying Agents appointed under the Indenture to DTC or its nominee, as the Holder of this Security. Initially, the Paying Agent shall
be HSBC Bank USA, National Association. The Company may change the Paying Agent without prior notice to the Holders, and in such an event the Company may act as Paying Agent. Payments of principal of and interest on this Security 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. 

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 AND IS NOT INSURED BY THE UNITED
STATES FEDERAL DEPOSIT INSURANCE CORPORATION OR ANY OTHER GOVERNMENT AGENCY OF THE UNITED STATES OR THE UNITED KINGDOM. 
 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 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.

 (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 under and governed by the Indenture, dated as of August 1, 2014 (herein called 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 HSBC Bank USA, National Association (“HBUS”), as Paying Agent and Registrar, as supplemented and amended
by the Seventh Supplemental Indenture, dated as of March 23, 2018 (the “Seventh Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), among the Company, the Trustee and HBUS, as
Paying Agent, Registrar and Calculation Agent, 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 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. 
 This Security is one of the series designated on the face hereof, limited to a principal
amount of $[•] 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. 
 All payments made under or with respect to this Security shall be paid without deduction or withholding for, or on
account of, any and all present and future taxes, levies, imposts, duties, charges, fees, deductions, or withholdings whatsoever imposed, levied, collected, withheld or assessed by or on behalf of the United Kingdom (or any political subdivision or
taxing authority thereof or therein having the power to tax) (each a “Taxing Jurisdiction”) unless required by law. If such deduction or withholding will at any time be required by the law of the Taxing Jurisdiction, the Company
shall pay such additional amounts in respect of any payments of interest on the Securities (but not, for the avoidance of doubt, in respect of the payment of principal in respect of the Securities) (“Additional Amounts”) as may be
necessary so that the net amounts (including Additional Amounts) paid to the Holders, after such deduction or withholding, shall be equal to the respective amounts of interest which the Holders would have been entitled to receive in respect of the
Securities in the absence of such deduction or withholding; provided that the foregoing will not apply to any such tax, levy, impost, duty, charge, fee, deduction or withholding which: (i) would not be payable or due but for the fact that the
Holder or Beneficial Owner is domiciled in, or is a national or resident of, or engaging in business or maintaining a permanent establishment or being physically present in, the Taxing Jurisdiction, or otherwise has some connection or former
connection with the Taxing Jurisdiction other than the holding or ownership of a Security, or the collection of principal or interest payments on, or the enforcement of, a Security; (ii) would not be payable or due but for the fact that the
certificate representing the relevant Securities (x) is presented for payment in the Taxing Jurisdiction or (y) is 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 would have been entitled to such Additional Amount on presenting the same for payment at the close of such thirty (30) day period; (iii) would not have been imposed if presentation for payment of
the certificate representing the relevant Securities had been made to a paying agent other than the paying agent to which the presentation was made; (iv) is imposed in respect of a Holder that is not the sole Beneficial Owner of the principal
or the interest, or a portion of either, or that is a fiduciary or partnership, but only to the extent that a beneficiary or settlor with respect to the fiduciary, a beneficial owner or member of the partnership would not have been entitled to the
payment of an Additional Amount had the beneficiary, settlor, beneficial owner or member received directly its beneficial or distributive share of the payment; (v) is imposed because of the failure to comply by the Holder or the Beneficial
Owner or the Beneficial Owner of any payment on such Securities with a request from the 

  
 A-7 

 Company addressed to the Holder or the Beneficial Owner, including a written request from the Company related to
a claim for relief under any applicable double tax treaty (x) to provide information concerning the nationality, residence, identity or connection with a taxing jurisdiction of the Holder or the Beneficial Owner or (y) to make any
declaration or other similar claim to satisfy any information or reporting requirement, if the information or declaration is required or imposed by a statute, treaty, regulation, ruling or administrative practice of the Taxing Jurisdiction as a
precondition to exemption from withholding or deduction of all or part of the tax, duty, assessment or other governmental charge; (vi) is imposed in respect of any estate, inheritance, gift, sale, transfer, personal property, wealth or similar
tax, duty assessment or other governmental charge; or (vii) is imposed in respect of any combination of the above items. 
 Whenever in
this Security or the Indenture there is mentioned, in any context, the payment of any interest, if any, on or in respect of any Security, such mention shall be deemed to include mention of the payment of Additional Amounts provided for in this
paragraph and in Section 10.04 of the Base Indenture, as amended by Section 6.01 of the Seventh Supplemental Indenture, to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof pursuant to
the provisions of this paragraph and in Section 10.04 of the Base Indenture, as amended by Section 6.01 of the Seventh Supplemental Indenture, and as if express mention of the payment of Additional Amounts (if applicable) were made in any
provisions hereof or thereof where such express mention is not made. 
 Any amounts to be paid by the Company on this Security shall be paid
net of any deduction or withholding imposed or required pursuant to (i) sections 1471 to 1474 of the Code or any associated regulations or other official guidance; (ii) any treaty, law, regulation or other official guidance enacted in any
other jurisdiction, or relating to an intergovernmental agreement between the United States and any other jurisdiction, which (in either case) facilitates the implementation of clause (i); or (iii) any agreement pursuant to the implementation
of clauses (i) or (ii) with the US Internal Revenue Service, the US government or any governmental or taxation authority in any other jurisdiction (a “FATCA Withholding Tax”), and the Company shall not be required to 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 this Security 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 shall not apply to payments made under this Security 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 under this paragraph and Section 10.04(d) of the Base Indenture shall be treated as paid to the Holder, and the Company shall not
pay Additional Amounts in respect of such deduction or withholding, except to the extent the provisions in this paragraph and Section 10.04 of the Base Indenture explicitly provide otherwise. 

Subject to the limitations specified below and in Sections 2.11 and 2.12 of the Seventh Supplemental Indenture, the Company may, at the
Company’s option in its sole discretion, redeem the Securities, in whole but not in part, on any 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 to have been cancelled as described on the face of this Security and in Sections 2.03 and 2.04 of the Seventh Supplemental Indenture) to (but excluding) the date fixed for redemption. 

  
 A-8 

 Subject to the limitations specified below and Section 2.12 of the Seventh Supplemental
Indenture, the Company may, at the Company’s option in its sole discretion, redeem this Security, in whole but not in part, at a redemption price equal to 100% of the principal amount of this Security then Outstanding, together with any accrued
but unpaid interest (which excludes any interest cancelled or deemed to have been cancelled as described on the face of this Security and in Sections 2.03 and 2.04 of the Seventh Supplemental Indenture) to (but excluding) the date fixed for
redemption, if, at any time, the Company determines that as a result of a change in, or amendment to, the laws of a Taxing Jurisdiction, including any treaty to which the relevant Taxing Jurisdiction is a party, or a change in an official
application or interpretation of those laws on or after the Issue Date, including a decision of any court or tribunal that becomes effective on or after the Issue Date: (i) on a subsequent date for the payment of interest on the Security the
Company would be required to pay any Additional Amounts; (ii) if the Company were to seek to redeem the Security on a subsequent date (for which purpose no consideration shall be given as to whether or not the Company would otherwise be
entitled to redeem the Security), the Company would be required to pay any Additional Amounts (notwithstanding the Company having made such endeavors as the Company considers reasonable); (iii) on a subsequent date for the payment of interest on the
Security, interest payments (or the Company’s funding costs as recognized in the Company’s accounts) under, or with respect to, the Security are no longer fully deductible for UK corporation tax purposes; (iv) the Security would no
longer be treated as loan relationships for UK tax purposes; (v) would, as a result of the Security being in issue, result in the Company not being able to have losses or deductions set against the profits or gains, or profits or gains offset
by the losses or deductions, of companies with which it is or would otherwise be so grouped for applicable UK tax purposes (whether under the group relief system current as of the Issue Date or any similar system or systems having like effect as may
from time to time exist); (vi) a future write-down of the principal amount of the Security or conversion of the Security into the Ordinary Shares would result in a UK tax liability, or the receipt of income or profit which would be subject to UK
tax, which would not otherwise have been the case as of the Issue Date; or (vii) the Security or any part thereof become treated as a derivative or an embedded derivative for UK tax purposes (each such change (or deemed change) in tax law or
regulation or the official application or interpretation thereof, a “Tax Event”). 
 Subject only to the Company’s
obligation to use such endeavors as provided in clause (ii) of the immediately preceding paragraph and Section 2.09(a)(ii) of the Seventh Supplemental Indenture, it shall be sufficient for the Company to deliver to the Trustee an
Officer’s Certificate stating that a Tax Event has occurred and is continuing and setting out the details thereof, as well as any opinion or certificate of an independent legal adviser on which such Officer’s Certificate is based. 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 shall be conclusive and binding
on the Holders and Beneficial Owners. 
 Subject to the limitations specified below and Section 2.12 of the Seventh Supplemental
Indenture, the Company may, at the Company’s option in its sole discretion, redeem this Security, in whole but not in part, at a redemption price equal to 100% of the principal amount of this Security then Outstanding, together with any accrued
but unpaid interest (which excludes any interest cancelled or deemed to have been cancelled as described on the face of this Security and in Sections 2.03 and 2.04 of the Seventh Supplemental Indenture) to (but excluding) the date fixed for
redemption, if the Company determines, at any time after the Issue Date, there is a change in the regulatory classification of the Securities that results or shall result in either their (i) exclusion in whole or in part from the HSBC
Group’s regulatory capital (other than as a consequence of an Automatic Conversion); or (ii) reclassification in whole or in part as a form of the HSBC Group’s regulatory capital that is lower than additional Tier 1 capital (a
“Capital Disqualification Event”). 

  
 A-9 

 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 pursuant to any of the four immediately preceding paragraphs. 

Before the Company may redeem this Security pursuant to any of the preceding paragraphs relating to the Company’s rights of redemption or
Sections 2.08, 2.09 and 2.10 of the Seventh Supplemental Indenture, the Company shall deliver via DTC prior notice of not less than thirty (30) days, nor more than sixty (60) days to the Holders provided, however, that in the
case of a Tax Event, no notice of redemption shall be given earlier than 90 days prior to the earliest date on which the Company would be obliged to pay Additional Amounts were a payment in respect of the Securities then due. Such notice shall
specify the Company’s election to redeem this Security and the date fixed for such redemption and shall be irrevocable except in the limited circumstances described in the remainder of this paragraph and clauses (b), (c) and (d) of
Section 2.11 of the Seventh Supplemental Indenture. If the Company has delivered a notice of redemption pursuant to this paragraph or Section 2.11 of the Seventh Supplemental Indenture, but as of the date specified for redemption in such
notice, the Solvency Condition is not satisfied in respect of the relevant redemption payment, 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. If the Company has delivered a notice of redemption pursuant to this paragraph or Section 2.11 of the Seventh Supplemental Indenture, but prior to the payment of the redemption amount with respect to such redemption a Capital
Adequacy Trigger Event occurs, such redemption notice shall be automatically rescinded and shall be of no force and effect, no payment in respect of the redemption amount shall be due and payable (and, for the avoidance of doubt, an Automatic
Conversion shall occur after such Capital Adequacy Trigger Event pursuant to the terms of this Security and Section 2.15(a) of the Seventh Supplemental Indenture). If the Company has delivered a notice of redemption pursuant to this paragraph
or Section 2.11 of the Seventh Supplemental Indenture, but prior to the payment of the redemption amount with respect to such redemption the Relevant UK Resolution Authority exercises its UK Bail-in Power
with respect to the Company, 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. If any of the events specified in each of the
preceding three sentences occurs, the Company shall promptly deliver notice to the Holders via DTC and to the Trustee and the Paying Agent directly, specifying the occurrence of the relevant event. 

Notwithstanding any other provision of this Security or the Seventh Supplemental Indenture, the Company may only redeem the Securities
pursuant to any of the preceding paragraphs relating to the Company’s rights of redemption or Sections 2.08, 2.09 and 2.10 of the Seventh Supplemental Indenture only if (i) the Company has obtained the Relevant Supervisory Consent,
(ii) in the case of a Special Event pursuant to Section 2.09 or Section 2.10 only, prior to the fifth anniversary of the Issue Date, if the Relevant Rules so oblige, the Company has demonstrated to the satisfaction of the Relevant
Regulator that (x) the Special Event was not reasonably foreseeable at the Issue Date and (y) in the case of a Tax Event, such Tax Event was material, (iii) the Company has complied with any alternative or additional pre-conditions to redemption, as applicable, set out in the Relevant Rules and (iv) the Company has provided notice in accordance with the immediately preceding paragraph or Section 2.11 of the Seventh
Supplemental Indenture. 
 Notwithstanding any other provision of the Indenture, including Section 6.05 of the Base Indenture, members
of the HSBC Group may purchase, repurchase or otherwise acquire any of the Securities then Outstanding at the same or differing prices in the open market, negotiated transactions or otherwise without giving prior notice to or obtaining any consent
from Holders, in accordance with the Relevant Rules and subject to obtaining the Relevant Supervisory Consent. For the avoidance of doubt, the Securities may be repurchased by members of the HSBC Group for market-making purposes in accordance with
any permission given by the Relevant Regulator pursuant to the Relevant Rules (including, without limitation, Article 29(3) of Commission Delegated Regulation (EU) No. 241/2014) within the limits prescribed in such permission. 

  
 A-10 

 If a Capital Adequacy Trigger Event has occurred, then the Automatic Conversion shall occur
without delay, but no later than one (1) month following the date on which it is determined such Capital Adequacy Trigger Event has occurred (such date, the “Conversion Date”). Effective upon, and following, a Capital Adequacy
Trigger Event, other than any amounts payable in the case of the Company’s winding-up or the appointment of an administrator for its administration pursuant to Section 5.01 of the Seventh
Supplemental Indenture, Holders and Beneficial Owners shall not have any rights against the Company with respect to repayment of the principal amount of this Security or payments of interest or any other amount on, or in respect of, this Security,
in each case that is not due and payable, which liabilities shall be automatically released. Accordingly, the principal amount of this Security shall equal zero at all times thereafter and any interest shall be cancelled or deemed to have been
cancelled pursuant to the terms of this Security and Section 2.03 of the Seventh Supplemental Indenture at all times thereafter, including 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, and shall not be due and payable. Although the principal amount of each Security shall equal zero after a Capital Adequacy Trigger Event, for the avoidance of doubt, the Tradable
Amount shall remain unchanged as a result of the Automatic Conversion. 
 The number of Conversion Shares to be issued to the Conversion
Shares Depository (or the relevant recipient pursuant to Section 2.15 of the Seventh Supplemental Indenture) on the Conversion Date shall equal the quotient obtained by dividing the (i) aggregate principal amount of this Security then
Outstanding immediately prior to the Automatic Conversion on the Conversion Date (the “Outstanding Amount”) by (ii) the Conversion Price, rounded down, if necessary, to the nearest whole number of Conversion Shares. The number
of Conversion Shares to be held by the Conversion Shares Depository for the benefit of a Holder shall equal the product obtained by multiplying (i) the number of Conversion Shares thus calculated by (ii) the quotient obtained by dividing
(x) the Tradable Amount held by such Holder on the Conversion Date by (y) the Outstanding Amount, such product to be 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. 
 Effective upon, and following, an Automatic
Conversion, all of the Company’s obligations under this Security shall be irrevocably and automatically released in consideration of the Company’s issuance of the Conversion Shares to the Conversion Shares Depository (or the relevant
recipient pursuant to Section 2.15 of the Seventh Supplemental Indenture), and under no circumstances shall such released obligations be reinstated. 

This Security shall remain in existence until the applicable Cancellation Date for the sole purpose of evidencing 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) in accordance with the terms of this
Security. 
 The procedures with respect to an Automatic Conversion are set forth in this Security and the Seventh Supplemental Indenture,
including Section 2.15 thereof. Such procedures are subject to change to reflect changes in DTC practices, and the Company may make changes to the procedures set forth in this Security and Section 2.15 of the Seventh Supplemental Indenture
to the extent reasonably necessary, in the opinion of the Company, to reflect such changes in DTC practices. 
 The Holders and Beneficial
Owners shall not at any time have the option to convert to this Security into Conversion Shares. 

  
 A-11 

 Notwithstanding anything to the contrary contained in the Indenture or this Security, once the
Company has delivered an Automatic Conversion Notice following the occurrence of a Capital Adequacy Trigger Event (or following an Automatic Conversion (if sooner)), (i) subject to the right of Holders and Beneficial Owners pursuant to
Section 4.03 of the Seventh Supplemental Indenture in the event of a failure by the Company to issue and deliver any Conversion Shares to the Conversion Shares Depository on the Conversion Date, the Holders and Beneficial Owners shall have no
rights whatsoever under the Indenture or this Security to instruct the Trustee or the Paying Agent 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 sentence, with respect to any rights of Holders or Beneficial Owners with respect to any payments under this Security that were unconditionally due and payable prior to the
date of the Automatic Conversion Notice or unless the Trustee or the Paying Agent is instructed in writing by the Company to act otherwise. 

Neither the Trustee nor the Paying Agent shall be liable with respect to (i) the calculation or accuracy of the End-point 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 End-point CET1 Ratio calculations of a Capital Adequacy Trigger Event to DTC, the Holders or the Beneficial Owners or (iii) any aspect of the Company’s decision to deliver an Automatic
Conversion Notice or the related Automatic Conversion. 
 Notwithstanding any other provision herein, by its acquisition of this Security,
each Holder (which, for these purposes, includes each Beneficial Owner) (i) consents to all of the terms and conditions of the Securities, including (x) the occurrence of a Capital Adequacy Trigger Event and any related Automatic
Conversion following a Capital Adequacy Trigger Event and (y) the appointment of the Conversion Shares Depository (or to the relevant recipient pursuant to Section 2.15 of the Seventh Supplemental Indenture), the issuance of the Conversion
Shares to the Conversion Shares Depository (or to the relevant recipient pursuant to Section 2.15 of the Seventh Supplemental Indenture),) and the potential sale of the Conversion Shares pursuant to a Conversion Shares Offer,
(ii) acknowledges and agrees that effective upon, and following, a Capital Adequacy Trigger Event, other than any amounts payable in the case of the Company’s winding-up or the appointment of an
administrator for its administration pursuant to Section 5.01 of the Seventh Supplemental Indenture, no Holder shall 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 on or in respect of this Security, in each case that is not due and payable, which liabilities of the Company shall be automatically released, (iii) acknowledges and agrees that events in, and related to, clause (i) may
occur without any further action on the part of such Holder, the Trustee or the Paying Agent, (iv) authorizes, directs and requests DTC and any direct participant in DTC or other intermediary through which it holds such Securities to take any
and all necessary action, if required, to implement the Automatic Conversion without any further action or direction on the part of such Holder, the Trustee or the Paying Agent and (v) 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. 
 Following the occurrence of an Automatic Conversion, the Company, in its sole and absolute discretion, may elect in the
Conversion Shares Office Notice that the Conversion Shares Depository make an offer of all or some of the Conversion Shares to all or some of the Shareholders at a cash price per Conversion Share equal to the Conversion Shares Offer Price (the
“Conversion Shares Offer”), subject to, and in accordance with, the terms of the Indenture. 

  
 A-12 

 The Conversion Price and the Conversion Shares Offer Price shall be subject to adjustment as
provided in Article III of the Seventh Supplemental Indenture. 
 If the Company elects, in its sole and absolute discretion, that a
Conversion Shares Offer be conducted, each Holder (which, for these purposes, includes each Beneficial Owner, by its acquisition of this Security, shall: (i) consent to (x) any Conversion Shares Offer and to the Conversion Shares
Depository’s using the Conversion Shares to settle any Conversion Shares Offer in accordance with the terms of this Security, notwithstanding that such Conversion Shares are held by the Conversion Shares Depository on behalf of Holders and
Beneficial Owners 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 this Security, and
(ii) irrevocably agree that (x) the Company, the Conversion Shares Depository (or the relevant recipient pursuant to Section 2.15 of the Seventh Supplemental Indenture) and the Conversion Shares Offer Agent, if any, may take any and
all actions necessary to conduct the Conversion Shares Offer in accordance with the terms of the Securities, and (y) none of the Company, the Trustee, the Paying Agent, 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). 
 Delivery of the Conversion Shares or Conversion
Shares Offer Consideration, as applicable, to the Holders and Beneficial Owners shall be made in accordance with the procedures set forth in Section 2.18 of the Seventh Supplemental Indenture, which remain subject to change to reflect changes
in DTC’s practices. 
 By its acquisition of the Securities, each Holder (which, for these purposes, includes each Beneficial Owner):
(i) acknowledges, accepts, consents and agrees, notwithstanding any other term of the Securities, the Indenture or any other agreements, arrangements or understandings between the Company 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 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 Company’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 Securities or the Indenture; (iii) the cancellation of the Securities; and/or (iv) the amendment or
alteration of the redemption date of the Securities or amendment of the amount of interest payable on the Securities, or the Interest Payment Dates, including by suspending payment for a temporary period; and (y) the variation of the terms of
the Securities or the Indenture, if necessary, to give effect to the exercise of any UK Bail-in Power by the Relevant UK Resolution Authority and (ii) consents to the exercise of any UK Bail-in Power as it may be imposed without any prior notice by the Relevant UK Resolution Authority of its decision to exercise such power with respect to the Securities. 

Notwithstanding anything to the contrary in the Indenture or this Security, including Article 9 of the Base Indenture, the Company hereby
agrees that it shall not amend the immediately preceding paragraph or Section 2.20(a) of the Seventh Supplemental Indenture without the prior consent of the Relevant Regulator. 

By its acquisition of the Securities, each Holder (which, for these purposes, includes each Beneficial Owner): (i) acknowledges and agrees
that neither a Capital Adequacy Trigger Event, an Automatic Conversion, a reduction or cancellation, in part or in full, of the Amounts Due (including 

  
 A-13 

 pursuant to Sections 2.03 and 2.04 of the Seventh Supplemental Indenture), the conversion thereof into another
security or obligation of the Company or another Person, as a result of the exercise of the UK Bail-in Power by the Relevant UK Resolution Authority with respect to the Securities, nor the exercise of the UK Bail-in Power by the Relevant UK Resolution Authority with respect to the Securities shall 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; (ii) 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 the UK Bail-in Power by the Relevant UK Resolution Authority with respect to the Securities; (iii) acknowledges and agrees that, upon the exercise of any UK Bail-in Power by the
Relevant UK Resolution Authority (a) the Trustee shall not be required to take any further directions from Holders under Section 5.12 of the Base Indenture and (b) none of the Base Indenture or the Seventh Supplemental Indenture shall
impose any duties upon the Trustee whatsoever with respect to the exercise of any UK Bail-in Power by the Relevant UK Resolution Authority; and (iv) shall be deemed to have authorized, directed and
requested DTC and any direct participant in DTC or other intermediary through which it holds such Securities to take any and all necessary action, if required, to implement the exercise of any UK 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, the Trustee or the Paying Agent. 

Upon the exercise of the UK Bail-in Power by the Relevant UK Resolution Authority with respect to the
Securities, the Company shall provide a written notice to Holders through DTC as soon as practicable regarding such exercise of the UK Bail-in Power. The Company shall also deliver a copy of such notice to the
Trustee for information purposes. 
 The Company’s obligations to indemnify the Trustee in accordance with Section 6.07 of the
Base Indenture shall survive any Automatic Conversion with respect to this Security. 
 It is the Parties’ intention that the
Company’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 with
respect to this Security. 
 In addition to the right to enter into supplemental indentures pursuant to Sections 9.01 and 9.02 of the Base
Indenture, the Company and the Trustee may enter into one or more indentures supplemental to the Indenture to modify and amend the terms of the Indenture or this Security, 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. 
 The
exercise of the UK Bail-in Power by the Relevant UK Resolution Authority with respect to this Security shall not constitute a Winding-Up Event or a Non-Payment Event. 
 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 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. 

  
 A-14 

 If a Winding-Up Event occurs before the occurrence of a
Capital Adequacy Trigger Event, the principal amount of the Securities 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 the Company fails to pay any amount that has become due and payable under the Securities, the Paying Agent shall notify the Trustee and, if
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 in accordance with the Indenture, 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 the terms of this Security or Section 2.03 or 2.04 of the Seventh Supplemental Indenture, the Company cancels any interest payment in respect of any Interest Payment Date or if such
interest payment is deemed to have been 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 shall 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 Section 4.02 of the Seventh
Supplemental Indenture, the Trustee may without further notice institute such proceedings against the Company as it 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 payment of any principal or interest, including Additional Amounts) (such obligation, a “Performance Obligation”);
provided the sole and exclusive remedy that the Trustee (acting on behalf of the Holders) and/or the Holders may seek under the Securities and the Indenture is specific performance under the laws of the State of New York; provided
further that to the extent any judgment or other award given in such proceedings requires the payment of money by the Company, whether by way of damages or otherwise (a “Monetary Judgment”), the Trustee (acting on behalf of
the Holders) and/or the Holders may not enforce, and shall not be entitled to enforce, or otherwise claim such Monetary Judgment against the Company, except by proving such Monetary Judgment in the winding-up
or administration of the Company. For the avoidance of doubt, any breach by the Company of any Performance Obligation shall not confer upon the Trustee (acting on behalf of the Holders) and/or the Holders any claim other than specific performance
and the Company shall not be obliged to pay any sum or sums, in cash or otherwise (including damages), as a consequence of the institution of any such proceedings, except where a Holder proves any Monetary Judgment in the Company’s winding-up or administration. 
 Other than the limited remedies specified in this Security and Article IV
of the Seventh Supplemental Indenture, and subject to the second paragraph following this sentence, no remedy against the Company shall be available to the Trustee (acting on behalf of the Holders) and to the Holders and Beneficial Owners, whether
for the recovery of amounts owing in respect of this Security 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 this Security 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 5.06 of the Base Indenture expressly survive any Default and are not subject to the subordination provisions of Section 5.01 of the Seventh Supplemental Indenture and the corresponding provisions of this
Security. 
 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 

  
 A-15 

 prudent person would exercise or use under the circumstances in the conduct of his or her own affairs. A
“Default” shall occur (i) upon the occurrence of a Winding-Up Event that occurs before the Conversion Date or (ii) upon the occurrence of a
Non-Payment Event or (iii) upon a breach by the Company of a Performance Obligation. Neither a Capital Adequacy Trigger Event, an Automatic Conversion, a cancellation or deemed cancellation of interest
(in each case, in whole or in part) in accordance with the terms of the Indenture and this Security nor the exercise of the UK Bail-in Power by the Relevant UK Resolution Authority with respect to this
Security shall be stated to be an Event of Default or a Default. 
 Notwithstanding the limitations on remedies specified in this Security
and under Article IV of the Seventh Supplemental Indenture, (i) 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 under the
provisions of the Indenture, and (ii) nothing shall impair the right of a Holder or Beneficial Owner 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 this Security; provided that, in the case of (i) and (ii) above, any payments in respect of, or arising from, this Security, including any payments or amounts resulting or arising from the enforcement of any rights under the Trust
Indenture Act in respect of this Security, shall be subject to the subordination provisions set forth in Section 5.01 of the Seventh Supplemental Indenture and the corresponding provisions of this Security. 

Holders of not less than a majority in aggregate principal amount of the Securities then Outstanding may on behalf of the Holders of all of
the Securities waive any past Default that results from a breach by the Company of a Performance Obligation; provided that (i) a Default in respect of a Performance Obligation, the modification or amendment of which would require the
consent of each Holder affected by it or (ii) any past Default that results from a Winding-Up Event or a Non-Payment Event, in either case, will require the waiver of each Holder affected by such Default.
Upon the occurrence of any waiver permitted by the immediately preceding sentence, such Default shall cease to exist, and any Default with respect to any series arising therefrom shall be deemed to have been cured and not to have occurred for every
purpose of the Base Indenture, but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. 

This Security shall constitute the Company’s direct, unsecured and subordinated obligations, ranking equally without any preference among
themselves. The rights and claims of the Holders and Beneficial Owners in respect of or arising from this Security shall be subordinated to the claims of Senior Creditors. If (x) 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 of the Company, the terms of
which reorganization, reconstruction or amalgamation (i) have previously been approved in writing by a majority of the Holders and (ii) do not provide that this Security shall thereby become redeemable or repayable in accordance with the
terms of this Security); or (y)    following the appointment of an administrator for the Company’s administration, the administrator declares, or gives notice that it intends to declare and distribute, a dividend, then
(i) if such events specified in (x) or (y) occur prior to the date on which a Capital Adequacy Trigger Event occurs, there shall be payable by the Company in respect of this Security (in lieu of any other payment by the Company), such
amount, if any, as would have been payable to a Holder if, on the day prior to the commencement of such winding-up or such administration and thereafter, such Holder were the holder of the most senior class of
preference shares in the Company’s capital, having an equal right to a return of assets in such 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 of assets in such 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 Company’s capital, but ranking junior to the claims of Senior Creditors, and on the assumption that the amount that such Holder was entitled to receive in respect of such senior
preference shares, on a return of assets in such winding-up or such administration, 

  
 A-16 

 were an amount equal to the principal amount of the relevant Security, together with any accrued but unpaid
interest thereon (to the extent not cancelled or deemed to have been cancelled) and any Monetary Judgment (if payable); and (ii) if such events specified in (x) or (y) above occur on or after the date on which a Capital Adequacy Trigger
Event occurs but prior to the Conversion Date, there shall be payable by the Company in respect of this Security (in lieu of any other payment by the Company) such amount, if any, as would have been payable to a Holder on a return of assets in such winding-up or such administration if the Conversion Date in respect of an Automatic Conversion had occurred immediately prior to the occurrence of such events specified in (x) or (y) above (and as a result,
such Holder were the holder of such number of Ordinary Shares as such Holder would have been entitled to receive on the Conversion Date, ignoring for these purposes the Company’s right to elect to make a Conversion Shares Offer). 

Other than in the event of a winding-up or administration of the Company as described in the
immediately preceding paragraph, payments in respect of or arising from this Security 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 this Security 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, 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 (i) it is able to pay its debts owed to Senior Creditors as they fall due and (ii) the Balance Sheet Condition has been met. A
certificate by the Auditors as to whether or not the Solvency Condition is met, on the basis of the information provided to the Auditors by the Company, will, in the absence of manifest error, be treated by the Company, the Trustee, the Holders, the
Beneficial Owners and all other interested parties as correct and sufficient evidence thereof. 
 The Indenture contains provisions
permitting the Company and the Trustee (i) without the consent of the Holders of any Contingent Convertible 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 Securities, and (ii) with the consent of the Holders of not less than a majority in aggregate principal amount of the Outstanding Contingent Convertible Securities of each series of Contingent Convertible
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; provided that, with respect to certain enumerated provisions, no such supplemental indenture may be entered into without the consent of the Holder of each Outstanding Contingent Convertible Security affected thereby. The Indenture
also permits the Holders of at least a majority in aggregate principal amount of the Outstanding Contingent Convertible Securities of each series to be affected, on behalf of the Holders of all Contingent Convertible Securities of such series, to
waive compliance by the Company with certain restrictive provisions of the Indenture. Any such consent or waiver by the Holder of this Security shall bind every future Holder 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 or such other Securities. 

No Holder shall 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 hereunder, unless 
 (a)    such Holder has previously given written notice to the Trustee
of a continuing Default specifying such Default and stating that such notice is a “Notice of Default” under the Indenture; (b) the Holders of not less than 25% in aggregate principal amount of the Outstanding Securities of this series
shall have made written request to the Trustee to institute proceedings in respect of such Default in its own name, as Trustee hereunder; (c) such Holder has offered to the Trustee security or indemnity satisfactory to the Trustee in its sole
discretion against the costs, expenses and liabilities to be incurred in compliance with 

  
 A-17 

 such request; (d) the Trustee for sixty (60) days after its receipt of such notice, request and offer
of indemnity has failed to institute any such proceeding; and (e) no direction inconsistent with such written request has been given to the Trustee during such sixty-day
(60-day) period by the Holders of a majority in aggregate principal amount of the Outstanding Securities of this series; it being understood and intended that no one or more Holders of this series shall have
any right in any manner whatsoever by virtue of, or by availing of, any provision of the Indenture to affect, disturb or prejudice the rights of any other such Holders or holders, or to obtain or to seek to obtain priority or preference over any
other such Holders or holders or to enforce any right under the Indenture, except in the manner herein provided and for the equal and ratable benefit of all Holders of this series. 

Subject to the terms of the Indenture, the Depository may surrender this Global Security or any portion thereof in exchange in whole or in
part for definitive Security on such terms as are acceptable to the Company and the Depository. Thereupon, the Company shall execute, and the Trustee shall authenticate and deliver such definitive Securities to the Registrar. In turn, the Registrar
shall deliver such definitive Securities, without service charge, as provided in the Indenture. 
 All covenants and agreements in the Base
Indenture, as supplemented and amended by the Seventh Supplemental Indenture, by the Company shall bind its successors and assigns, whether so expressed or not. 

The Holders (which, for these purposes, includes Beneficial Owners) that acquire the Securities in the secondary market and any successors,
assigns, heirs, executors, administrators, trustees in bankruptcy and legal representatives of any Holder shall be deemed to acknowledge, accept, agree to be bound by and consent to the same provisions specified herein and in the Indenture to the
same extent as the Holders 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 related to the UK Bail-in Power and related to a Capital Adequacy Trigger Event. 
 This Security and the Seventh
Supplemental Indenture shall be governed by, and construed in accordance with, the laws of the State of New York, except that Article V of the Seventh Supplemental Indenture and the corresponding provision in this Security are governed by, and
construed in accordance with, the laws of England and Wales.

March 23, 2028 and Every Five Years Thereafter) (CUSIP: 404280 BP3, ISIN: US404280BP39) – Notice to DTC, the Trustee, the Paying Agent, Holders and Beneficial Owners of the Occurrence of a Capital Adequacy Trigger Event 

This notice is in relation to HSBC Holdings plc’s (the “Company”) $1,800,000,000 6.500% Perpetual Subordinated Contingent Convertible
Securities (Callable March 23, 2028 and Every Five Years Thereafter) (CUSIP: 404280 BP3, ISIN: US404280BP39) issued on March 23, 2018 (the “Securities”) pursuant to the Contingent Convertible Securities Indenture, dated as
of August 1, 2014 (as amended and supplemented from time to time), among the Company, The Bank of New York Mellon, London Branch, as trustee (the “Trustee”), and HSBC Bank USA, National Association (“HBUS”), as
registrar and paying agent, as supplemented by the Seventh Supplemental Indenture, dated March 23, 2018, among the Company, the Trustee and HBUS, as registrar, paying agent and calculation agent (together, the “Indenture”), and
pursuant to the prospectus supplement dated March 19, 2018, supplementing the prospectus dated

 B-1 

 February 23, 2018. Capitalized terms used herein and not defined herein shall have the respective meanings
ascribed to such terms in the Indenture. The Company hereby notifies DTC, the Holders and Beneficial Owners that a Capital Adequacy Trigger Event has occurred with respect to the Securities. Such Capital Adequacy Trigger Event has occurred because
the End-point CET1 Ratio as of [Date of Capital Adequacy Trigger Event] was less than 7.0% . 
 Upon the occurrence
of a 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] [Conversion Date], based on the Conversion Price, which is
[Conversion Price]. Upon the Automatic Conversion, all of the Company’s obligations under the Securities shall be irrevocably and automatically released in consideration of the Company’s issuance of ordinary shares of the Company
(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 right to receive Conversion Shares or the Conversion Shares Offer Consideration, as applicable, from the Conversion Shares Depository (or the relevant recipient in accordance with the terms of the Securities). 

In addition, the terms of the Securities provide that the Company may, in its sole and absolute discretion, elect that a Conversion Shares Offer be conducted.
Within ten (10) Business Days of the Conversion Date, the Company shall deliver to DTC, the Holders and the Beneficial Owners a Conversion Shares Offer Notice specifying, among other things, whether or not the Company has elected that a
Conversion Shares Offer be conducted and the Suspension Date. The Securities may continue to trade until the Suspension Date. 
 Accordingly, the Company
hereby instructs DTC to indicate to all participants that payments of principal and interest are no longer payable under the Securities as of [Date of Capital Adequacy Trigger Event] and that the Securities shall have no further entitlement
to interest or principal as of such date by making a note to that effect in its systems. 
 The Company further requests DTC to post this notice on its
Reorganization Inquiry for Participants System (or such other system as DTC uses for providing notices to holders of securities).

or any Beneficial Owner have any inquiries, please contact:

 Exhibit C 

Form of Capital Adequacy Trigger Event Officers’ Certificate 

HSBC HOLDINGS PLC 
 Capital
Adequacy Trigger Event Officers’ Certificate 
 This Capital Adequacy Trigger Event Officers’ Certificate is being delivered in relation to
HSBC Holdings plc’s (the “Company”) $1,800,000,000 6.500% Perpetual Subordinated Contingent Convertible Securities (Callable March 23, 2028 and Every Five Years Thereafter) (CUSIP: 404280 BP3, ISIN: US404280BP39) issued on
March 23, 2018 (the “Securities”) pursuant to the Contingent Convertible Securities Indenture, dated as of August 1, 2014 (as amended and supplemented from time to time, the “Base Indenture”), among the
Company, The Bank of New York Mellon, London Branch, as trustee (the “Trustee”), and HSBC Bank USA, National Association (“ HBUS”), as registrar and paying agent, as supplemented by the Seventh Supplemental
Indenture (the “Seventh Supplemental Indenture”), dated March 23, 2018, among the Company, the Trustee and HBUS, as registrar, paying agent and calculation agent, and pursuant to the prospectus supplement dated March 19,
2018, supplementing the prospectus dated February 23, 2018 (together, the “Prospectus”). Capitalized terms used herein and not defined herein shall have the respective meanings ascribed to such terms in the Indenture. 

Pursuant to Section 1.02 of the Base Indenture and Section 2.15(b) of the Seventh Supplemental Indenture, the undersigned, being Authorized Officers
and authorized by the Company to give this certificate, each hereby certify as follows: 
  

	(a)	I have read the provisions of the Base Indenture and those of the Seventh Supplemental Indenture, setting forth certain provisions in respect of the occurrence of a Capital Adequacy Trigger Event, including
Section 2.15(b) of the Seventh Supplemental Indenture, and the definitions relating thereto; 

  

	(b)	I have reviewed such corporate records and such other documents as I have deemed necessary as a basis for the opinion hereinafter expressed; 

 

	(c)	I have also made such other examinations and investigations as I have deemed necessary to enable me to express an informed opinion as to the matters set forth in (d) below; and 

 

	(d)	a Capital Adequacy Trigger Event has occurred with respect to the Securities. Such Capital Adequacy Trigger Event has occurred because the End-point CET1 Ratio as of [Date of
Capital Adequacy Trigger Event], as calculated by the Company in accordance with the Indenture and the Securities on such date, was less than 7.0%. 

Concurrently with the delivery of this Capital Adequacy Trigger Event Officers’ Certificate, the Company is delivering to DTC an Automatic Conversion
Notice as a notice to DTC and for publication as a notice to Holders and Beneficial Owners in the form set forth in Exhibit B to the Seventh Supplemental Indenture. 

The Trustee is entitled to conclusively rely on and accept this 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 this Capital Adequacy Trigger Event Officers’ Certificate shall be conclusive and binding on the Trustee, the Paying Agent, the
Holders (as defined in the Base Indenture) and Beneficial Owners (as defined in the Seventh Supplemental Indenture).
