in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a
condition precedent to the validity of any action taken in reliance upon such waiver. In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such
notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

Trustee shall not be obligated and shall have no responsibility with respect to any failure by the Company to take any such action. The Company hereby irrevocably submits (for the purposes of any such suit or proceeding) to the non-exclusive jurisdiction of any such court in which any such suit or proceeding is so instituted, and waives, to the extent it may effectively do so, any right to trial by jury and any objection it may have now or
hereafter to the laying of the venue of any such suit or proceeding. To the extent that the Company may be entitled, in any jurisdiction in which judicial proceedings may at any time be commenced with respect to or arising out of this Contingent
Convertible Capital Securities Indenture to claim for itself or its revenues, assets or properties immunity (whether by reason of sovereign immunity or otherwise) from suit, from the jurisdiction of any court (including, but not limited to, any
court of the United States of America or the State of New York) or from any legal process with respect to itself or its property, from attachment prior to judgment, from set-off, from execution of a judgment,
from the grant of injunctive relief, whether prior to or after judgment, or from any other legal process (including, without limitation, in relation to enforcement of any arbitration award), and to the extent that in any such jurisdiction there may
be attributed such an immunity (whether or not claimed), the Company hereby irrevocably agrees not to claim and hereby irrevocably waives such immunity and consents to the grant of any such relief.

arising out of, or as a result of, such deficiency. This indemnity shall constitute an obligation separate and independent from the other obligations contained in this Contingent Convertible Capital Securities Indenture or the Contingent Convertible
Capital Securities, shall give rise to a separate and independent cause of action, shall apply irrespective of any indulgence granted by any Holder or the Trustee from time to time and shall continue in full force and effect notwithstanding any

certificate shall be amended by the Company whenever a person is to be added or deleted from the listing. If the Company elects to give the Trustee Instructions using Electronic Means and the Trustee in its discretion elects to act upon such
Instructions, the Trustee’s understanding of such Instructions shall be deemed controlling. The Company understands and agrees that the Trustee cannot determine the identity of the actual sender of such Instructions and that the Trustee shall
conclusively presume that directions that purport to have been sent by an Authorized Officer listed on the incumbency certificate provided to the Trustee have been sent by such Authorized Officer. The Company shall be responsible for ensuring that
only Authorized Officers transmit such Instructions to the Trustee and that the Company and all Authorized Officers are solely responsible to safeguard the use and confidentiality of applicable user and authorization codes, passwords and/or
authentication keys upon receipt by the Company. The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee’s reliance upon and compliance with such Instructions notwithstanding such
directions conflict or are inconsistent with a subsequent written instruction. The Company agrees: (i) to assume all risks arising out of the use of Electronic Means to submit Instructions to the Trustee, including without limitation the risk
of the Trustee acting on unauthorized Instructions, and the risk of interception and misuse by third parties; (ii) that it is fully informed of the protections and risks associated with the various methods of transmitting Instructions to the
Trustee and that there may be more secure methods of transmitting Instructions than the method(s) selected by the Company; (iii) that the security procedures (if any) to be followed in connection with its transmission of Instructions provide to
it a commercially reasonable degree of protection in light of its particular needs and circumstances; and (iv) to notify the Trustee immediately upon learning of any compromise or unauthorized use of the security procedures.

Convertible Capital Securities Indenture. Notwithstanding the foregoing, if any Contingent Convertible Capital Security shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver
such Contingent Convertible Capital Security to the Trustee for cancellation as provided in Section 3.13, for all purposes of this Contingent Convertible Capital Securities Indenture, such Contingent Convertible Capital Security shall be deemed
never to have been authenticated and delivered hereunder and shall never be entitled to the benefit of this Contingent Convertible Capital Securities Indenture.

 Section 3.04. Temporary Contingent Convertible Capital Securities. Pending the
preparation of definitive Contingent Convertible Capital Securities of any series, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Contingent Convertible Capital Securities substantially of the
tenor of the definitive Contingent Convertible Capital Securities in lieu of which they are issued, which Contingent Convertible Capital Securities may be printed, lithographed, typewritten, photocopied or otherwise produced. Temporary Contingent
Convertible Capital Securities may be issued as registered Contingent Convertible Capital Securities in any authorized denomination, and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such
Contingent Convertible Capital Securities may determine, all as evidenced by such execution. 
 If temporary Contingent Convertible Capital
Securities of any series are issued, the Company will cause, if so required by the terms of such temporary Contingent Convertible Capital Securities, definitive Contingent Convertible Capital Securities of such series to be prepared without
unreasonable delay. After the preparation of definitive Contingent Convertible Capital Securities of such series, the temporary Contingent Convertible Capital Securities of such series shall be exchangeable for definitive Contingent Convertible
Capital Securities of such series containing identical terms and provisions upon surrender of the temporary Contingent Convertible Capital Securities of such series at the office or agency of the Company in a Place of Payment for that series,
without charge to the Holder. Upon surrender for cancellation of any one or more temporary Contingent Convertible Capital Securities of any series the Company shall execute, and the Trustee shall authenticate and deliver in exchange therefor, a like
aggregate Liquidation Preference of definitive Contingent Convertible Capital Securities of the same series of authorized denominations containing identical terms and provisions. Until so exchanged, unless otherwise provided therein or in a
supplemental indenture relating thereto, the temporary Contingent Convertible Capital Securities of any series shall in all respects be entitled to the same benefits (but shall be subject to all the limitations of rights) under this Contingent
Convertible Capital Securities Indenture as definitive Contingent Convertible Capital Securities of such series. 
 Section 3.05.
Registration, Registration of Transfer and Exchange. 
 (a) Global Securities. This Section 3.05(a) shall apply to Global
Securities unless otherwise specified, as contemplated by Section 3.01. 
 Except as otherwise specified as contemplated by
Section 3.01 hereof, the Contingent Convertible Capital Securities shall be initially issued and represented by one or more Global Securities in registered form, which shall be authenticated as contemplated by this Contingent Convertible
Capital Securities Indenture. 
 Each Global Security authenticated under this Contingent Convertible Capital Securities Indenture shall be
registered in the name of the Depositary designated for such Global Security or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Security shall constitute a single Contingent
Convertible Capital Security for all purposes of this Contingent Convertible Capital Securities Indenture. Except as otherwise specified as contemplated by Section 3.01 hereof, each Global Security authenticated under this Contingent
Convertible Capital Securities Indenture shall be initially registered in the name of DTC or its nominee only. 

  
 39 

 Unless the Global Security is presented by an authorized representative of the Holder to the
Company or its agent for registration of transfer, exchange or payment, and any certificate issued is registered in the name of a nominee of the Holder and any payment is made to such nominee, any transfer, pledge or other use of the Global Security
for value or otherwise shall be wrongful since the registered owner of such Global Security, the nominee of the Holder, has an interest in such Global Security. 

Except as otherwise specified as contemplated by Section 3.01 hereof, any Global Security shall be exchangeable for definitive Contingent
Convertible Capital Securities only as provided in this paragraph. A Global Security shall be exchangeable pursuant to this Section only (i) if the relevant Depositary notifies the Company that it is unwilling or unable to continue to act as
Depositary and a successor depositary is not appointed by the Company within 120 days of such notification, (ii) if, in the event of a winding-up of the Company, the Company fails to make a payment on the
Contingent Convertible Capital Securities when due or (iii) at any time if the Company at its option and in its sole discretion determines that the Global Securities of a particular series should be exchanged for definitive Contingent
Convertible Capital Securities of that series. Any Global Security that is exchangeable pursuant to the preceding sentence shall be exchangeable for, unless otherwise specified or contemplated by Section 3.01, definitive Contingent Convertible
Capital Securities bearing Distributions (if any) at the same rate or pursuant to the same formula, having the same date of issuance, the same date or dates from which such Distributions shall accrue, the same Distribution Dates or manner of
determination of such Distribution Dates, redemption provisions, if any, specified currency and other terms and of differing denominations aggregating a like amount as the Global Security so exchangeable. Definitive Contingent Convertible Capital
Securities shall be registered in the names of the owners of the beneficial interests in such Global Securities as such names are from time to time provided by the Holder to the Trustee. 

Any Global Security that is exchangeable pursuant to the preceding paragraph, unless otherwise specified as contemplated by Section 3.01,
shall be exchangeable for Contingent Convertible Capital Securities issuable in authorized denominations of a like aggregate Liquidation Preference and tenor. 

No Global Security may be transferred except as a whole by the Holder to a nominee of the Holder or by the Holder or any such nominee to a
successor of the Holder or a nominee of such successor. Except as provided above, owners solely of beneficial interests in a Global Security shall not be entitled to receive physical delivery of Contingent Convertible Capital Securities in
definitive form and will not be considered the holders thereof for any purpose under this Contingent Convertible Capital Securities Indenture. 

In the event that a Global Security is surrendered for redemption in part pursuant to Section 12.07, the Company shall execute, and the
Trustee shall authenticate and deliver to the Holder of such Global Security, without service charge, a new Global Security in a denomination equal to and in exchange for the unredeemed portion of the Liquidation Preference of the Global Security so
surrendered. 

  
 40 

 The Agent Members and any beneficial owners shall have no rights under this Contingent
Convertible Capital Securities Indenture with respect to any Global Security held on their behalf by a Holder, and such Holder may be treated by the Company, the Trustee, and any agent of the Company or the Trustee as the owner of such Global
Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee, or any agent of the Company or the Trustee, from giving effect to any written certification, proxy or other authorization
furnished by a Holder or impair, as between any such Holder or other clearance service and its Agent Members and Holders the operation of customary practices governing the exercise of the rights of a holder of any security, including without
limitation the granting of proxies or other authorization of participants to give or take any request, demand, authorization, direction, notice, consent, waiver or other action which a Holder is entitled to give or take under this Contingent
Convertible Capital Securities Indenture. 
 In connection with any exchange of interests in a Global Security for definitive Contingent
Convertible Capital Securities of another authorized form, as provided in this Section 3.05(a), then without unnecessary delay but in any event not later than the earliest date on which such interests may be so exchanged, the Company shall
deliver to the Trustee definitive Contingent Convertible Capital Securities in aggregate Liquidation Preference equal to the Liquidation Preference of such Global Security or the portion to be exchanged, executed by the Company. On or after the
earliest date on which such interests may be so exchanged, such Global Security shall be surrendered by the Holder to the Trustee, as the Company’s agent for such purpose, to be exchanged, in whole or from time to time in part, for definitive
Contingent Convertible Capital Securities without charge (in which case the Company or Trustee may require payment of any taxes or governmental charges arising) and the Trustee shall authenticate and deliver, in exchange for each portion of such
Global Security, an equal aggregate Liquidation Preference of definitive Contingent Convertible Capital Securities of authorized denominations as the portion of such Global Security to be exchanged. Any Global Security that is exchangeable pursuant
to this Section 3.05 shall be exchangeable for Contingent Convertible Capital Securities issuable in the denominations specified as contemplated by Section 3.01 and registered in such names as the Holder of such Global Security shall
direct. If a definitive Contingent Convertible Capital Security is issued in exchange for any portion of a Global Security after the close of business at the office or agency where such exchange occurs on any record date and before the opening of
business at such office or agency on the relevant Distribution Date, Distributions will not be payable on such Distribution Date in respect of such definitive Contingent Convertible Capital Security, but will be payable on such Distribution Date
only to the Person to whom Distributions in respect of such portion of such Global Security are payable. 
 A Depositary may grant proxies
and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a holder is entitled to take under this Contingent Convertible Capital Securities Indenture with respect
to the Contingent Convertible Capital Securities. 

  
 41 

 (b) Except as otherwise specified pursuant to Section 3.01, Contingent Convertible
Capital Securities of any series may only be exchanged for a like aggregate Liquidation Preference of Contingent Convertible Capital Securities of such series of other authorized denominations containing identical terms and provisions. Contingent
Convertible Capital Securities to be exchanged shall be surrendered at an office or agency of the Company designated pursuant to Section 11.02 for such purpose, and the Company shall execute, and the Trustee shall authenticate and deliver, in
exchange therefor the Contingent Convertible Capital Security or Contingent Convertible Capital Securities of the same series which the Holder making the exchange shall be entitled to receive. 

Except as otherwise specified pursuant to Section 3.01, the Company shall cause to be kept in the Corporate Trust Office of the Trustee a
register (the register maintained in such office and in any other office or agency of the Company in a Place of Payment being herein sometimes collectively referred to as the “Contingent Convertible Capital Security Register” in
which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Contingent Convertible Capital Securities and of transfers of such Contingent Convertible Capital Securities. Except as otherwise
specified pursuant to Section 3.01, the Trustee is hereby appointed “Contingent Convertible Capital Security Registrar” for the purpose of registering Contingent Convertible Capital Securities and transfers of Contingent
Convertible Capital Securities as herein provided. 
 Contingent Convertible Capital Securities shall be transferable only on the Contingent
Convertible Capital Security Register. Upon surrender for registration of transfer of any Contingent Convertible Capital Security of any series, together with the form of transfer endorsed on it, duly completed and executed at an office or agency of
the Company designated pursuant to Section 11.02 for such purpose, the Company shall execute, and the Trustee shall authenticate and deliver to the address specified in the form of transfer, within three Business Days, in the name of the
designated transferee or transferees, one or more new Contingent Convertible Capital Securities of the same series of any authorized denominations containing identical terms and provisions, of a like aggregate Liquidation Preference. If only part of
a Contingent Convertible Capital Security is transferred, a new Contingent Convertible Capital Security of an aggregate Liquidation Preference equal to the amount not being transferred shall be executed by the Company, and authenticated and
delivered by the Trustee to the transferor, in the name of the transferor, within three Business Days of receiving the Contingent Convertible Capital Security. The new Contingent Convertible Capital Security will be delivered to the transferor by
uninsured post at the risk of the transferor to the address of the transferor appearing in the Contingent Convertible Capital Security Register. The new Contingent Convertible Capital Security will be delivered to the transferor by uninsured post at
the risk of the transferor to the address of the transferor appearing in the Contingent Convertible Capital Security Register. A new Contingent Convertible Capital Security of an aggregate Liquidation Preference equal to the amount being transferred
shall be delivered by the Trustee to the transferee, in the name of the transferee, within three Business Days after the Trustee acting as Paying Agent pursuant to Section 11.02 receives the Contingent Convertible Capital Security. The new
Contingent Convertible Capital Security will be delivered to the transferee by uninsured post at the risk of the transferee to the address of the transferee specified in the form of transfer. 

  
 42 

 All Contingent Convertible Capital Securities issued upon any registration of transfer or
exchange of Contingent Convertible Capital Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Contingent Convertible Capital Securities Indenture, as the Contingent
Convertible Capital Securities surrendered upon such registration of transfer or exchange. 
 Every Contingent Convertible Capital Security
presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Contingent
Convertible Capital Security Registrar duly executed, by the Holder thereof or his attorney duly authorized in writing. 
 No service charge
shall be made for any registration of transfer or exchange of Contingent Convertible Capital Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any
registration of transfer or exchange of Contingent Convertible Capital Securities, other than exchanges pursuant to Section 3.04, 10.06 or 12.07 not involving any transfer. 

The Company shall not be required (i) to issue, register the transfer of or exchange any Contingent Convertible Capital Security of any
series during a period beginning at the opening of business 15 days before the day of the giving of a notice of redemption of Contingent Convertible Capital Securities of such series selected for redemption under Section 12.03 and ending at the
close of business on the day of the giving of such notice, or (ii) to register the transfer of or exchange any Contingent Convertible Capital Security so selected for redemption in whole or in part, except the unredeemed portion of any
Contingent Convertible Capital Securities being redeemed in part. 
 Section 3.06. Mutilated, Destroyed, Lost and Stolen Contingent
Convertible Capital Securities. If any mutilated Contingent Convertible Capital Security (including any Global Security) is surrendered to the Trustee, the Company may execute and the Trustee shall, in the case of a Contingent Convertible
Capital Security, authenticate and deliver, in exchange therefor a new Contingent Convertible Capital Security of the same series containing identical terms and provisions and of like amount, and bearing a number not contemporaneously outstanding.

 If there shall be delivered to the Company and to the Trustee (i) evidence to their satisfaction of the destruction, loss or theft
of any Contingent Convertible Capital Security (including any Global Security), and (ii) such security or indemnity as may be required by them to save each of them and any agent of any of them harmless, then, in the absence of notice to the
Company or the Trustee that such Contingent Convertible Capital Security has been acquired by a bona fide purchaser, the Company shall execute and upon the Company’s request the Trustee shall authenticate and deliver, in lieu of any such
destroyed, lost or stolen Contingent Convertible Capital Security, if any, a new Contingent Convertible Capital Security of the same series containing identical terms and provisions and of like amount, and bearing a number not contemporaneously
outstanding. 

  
 43 

 In case any such mutilated, destroyed, lost or stolen Contingent Convertible Capital
Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Contingent Convertible Capital Security pay such Contingent Convertible Capital Security. 

Upon the issuance of any new Contingent Convertible Capital Security under this Section, the Company may require the payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. 

Every new Contingent Convertible Capital Security of any series issued pursuant to this Section in lieu of any destroyed, lost or stolen
Contingent Convertible Capital Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Contingent Convertible Capital Security shall be at any time enforceable by anyone,
and shall be entitled to all the benefits of this Contingent Convertible Capital Securities Indenture equally and proportionately with any and all other Contingent Convertible Capital Securities of that series duly issued hereunder. 

The provisions of this Section, as amended or supplemented pursuant to this Contingent Convertible Capital Securities Indenture, are exclusive
and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Contingent Convertible Capital Securities. 

Section 3.07. Distributions. Rights Preserved. 

Except as otherwise provided in a supplemental indenture: 

(a) The Company will make any payments of Distributions and Liquidation Preference on any particular series of Contingent Convertible Capital
Securities on the dates that are determined pursuant to Section 3.01. 
 (b) The Contingent Convertible Capital Securities of any
series will accrue non-cumulative cash distributions (“Distributions”) as may be specified in, or determined in accordance with Section 3.01. 

(c) The Company has no obligation to make Distributions with respect to any series of Contingent Convertible Capital Securities. 

(d) Except as otherwise provided as contemplated by Section 3.01 with respect to any series of Contingent Convertible Capital Securities,
Distributions, if any, on any Contingent Convertible Capital Securities which are payable, and are paid or duly provided for, on any Distribution Payment Date shall be paid to the Person in whose name that Contingent Convertible Capital Security (or
one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such Distributions. 

  
 44 

 (e) In the case of Contingent Convertible Capital Securities where payment is to be made in
dollars, payment at the Principal Paying Agent’s office outside The City of New York will be made in dollars by check drawn on, or, at the request of the Holder, by transfer to a dollar account maintained by the payee with, a bank in The City
of New York. 
 (f) In the case of Contingent Convertible Capital Securities where payment is to be made in a Foreign Currency, payment will
be made as established pursuant to Section 3.01. 
 (g) Subject to the foregoing provisions of this Section 3.07, each Contingent
Convertible Capital Security delivered under this Contingent Convertible Capital Securities Indenture upon registration of transfer of or in exchange for or in lieu of any other Contingent Convertible Capital Security shall carry the rights to
accrued and unpaid Distributions, if any, and to accrue Distributions, which were carried by such other Contingent Convertible Capital Security. 

Section 3.08. Distributions Discretionary.  

(a) The Company may elect, in its sole and absolute discretion, to cancel the payment of any Distribution in whole or in part at any time that
it deems necessary or desirable, and for any reason. 
 (b) Distributions on the Contingent Convertible Capital Securities will be non-cumulative. Accordingly, if any Distribution (or part thereof) is not paid in respect of the Contingent Convertible Capital Securities of any series as a result of any election of the Company to cancel such
Distribution pursuant this Section 3.08 or the limitations on payment set out in this Section 3.08 and Section 3.09 then the right of the Holders to receive the relevant Distribution (or part thereof) in respect of the relevant
Distribution Period will be extinguished and the Company will have no obligation to pay such Distribution (or part thereof) accrued for such Distribution Period or to pay any interest thereon, whether or not Distributions on the Contingent
Convertible Capital Securities of such series are paid in respect of any future Distribution Period. 
 (c) No such election to cancel the
payment of any Distribution (or part thereof) pursuant to this Section 3.08 or non-payment of any Distribution (or part thereof) as a result of the limitations on payment set out in Section 3.09 will
constitute an event of default, an Enforcement Event or the occurrence of any event related to the insolvency of the Company or entitle holders to take any action to cause such Distribution to be paid or the dissolution, liquidation or winding-up of the Company or in any way limit or restrict the Company from making any distribution or equivalent payment in connection with any instrument ranking junior to the Contingent Convertible Capital
Securities of such series (including, without limitation, any CET1 Capital of the Company or the Group) or in respect of any other Parity Security or other Security. 

  
 45 

 Section 3.09. Restrictions on Payments. 

(a) To the extent that (i) the Company has insufficient Available Distributable Items to make Distributions on the Contingent Convertible
Capital Securities of such series scheduled for payment in the then current financial year and any equivalent payments scheduled to be made in the then current financial year in respect of any other Parity Securities or CET1 Capital securities then
outstanding to the extent permitted by the Applicable Banking Regulations, in each case excluding any portion of such payments already accounted for in determining the Available Distributable Items, and/or (ii) the Regulator, in accordance with
Applicable Banking Regulations, requires the Company to cancel the relevant Distribution in whole or in part, then the Company will, without prejudice to the right above to cancel at its discretion the payment of any such Distributions on the
Contingent Convertible Capital Securities of such series at any time, make partial or, as the case may be, no payment of the relevant Distribution on the Contingent Convertible Capital Securities of such series. 

(b) No Distributions will be made on the Contingent Convertible Capital Securities of any series until the Maximum Distributable Amount (if
required) is calculated and if and to the extent that such payment would cause the Maximum Distributable Amount (if any) then applicable to the Company and/or the Group to be exceeded. 

Section 3.10. Agreement to Distribution Cancellation. 

(a) By acquiring contingent convertible capital securities, Holders and beneficial owners of the contingent convertible capital securities
acknowledge and agree that: 
 (i) Distributions are payable solely at the Company’s discretion, and no amount of
Distribution shall become or remain due and payable in respect of the relevant Distribution Period to the extent that it has been cancelled by the Company at the Company’s sole discretion and/or deemed cancelled as a result of our having
insufficient Available Distributable Items or as a result of the Regulator requiring the Company to cancel the Distributions or as a result of exceeding the Maximum Distributable Amount (if any) then applicable to the Company and/or the Group; and

 (ii) a cancellation or deemed cancellation of Distributions (in each case, in whole or in part) in accordance with the
terms of this Contingent Convertible Capital Securities Indenture or applicable supplemental indenture and the Contingent Convertible Capital Securities shall not constitute an Enforcement Event or other default under the terms of the Contingent
Convertible Capital Securities or the Capital Securities Indenture. 

  
 46 

 (b) Distributions will only be due and payable on a Distribution Payment Date to the extent
they are not cancelled or deemed cancelled previously or thereafter in accordance with Section 3.08, Section 3.09, Section 3.10, Section 6.02 and Section 4.01. Any Distributions cancelled or deemed cancelled (in each case,
in whole or in part) in the circumstances described herein shall not be due and shall not accumulate or be payable at any time thereafter, and holders of the contingent convertible capital securities shall have no rights thereto or to receive any
additional Distributions or compensation as a result of such cancellation or deemed cancellation. 
 Section 3.11. Notice of
Distribution Cancellation. If practicable, the Company will provide notice of any cancellation or deemed cancellation of Distributions (in each case, in whole or in part) to the holders of the Contingent Convertible Capital Securities through
the relevant Clearing System (or, if the Contingent Convertible Capital Securities are held in definitive form, to the holders of the Contingent Convertible Capital Securities directly at their addresses shown on the register for the Contingent
Convertible Capital Securities) and to the Trustee directly on or prior to the relevant Distribution Payment Date. Failure to provide such notice will have no impact on the effectiveness of, or otherwise invalidate, any such cancellation or deemed
cancellation of Distributions (and accordingly, such Distributions will not be due and payable), or give the holders of the Contingent Convertible Capital Securities any rights as a result of such failure. 

Section 3.12. Persons Deemed Owners. Prior to due presentment of a Contingent Convertible Capital Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Contingent Convertible Capital Security is registered as the owner of such Contingent Convertible Capital Security for the purpose
of receiving payment of Liquidation Preference of and (subject to Section 3.05 and Section 3.07) any Distribution on such Contingent Convertible Capital Security and for all other purposes whatsoever, whether or not such Contingent
Convertible Capital Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary. The aggregate Liquidation Preference of the Contingent Convertible Capital
Securities of any series shall be reflected on the books and records of the Contingent Convertible Capital Security Registrar. 

  
 47 

 None of the Company, the Trustee, the Paying Agent or the Contingent Convertible Capital
Security Registrar shall have any responsibility or obligation to any beneficial owner in a Global Security, any Agent Member or any other Person with respect to the accuracy of the records of the Depositary or its nominee or of any Agent Member,
with respect to any ownership interest in the Contingent Convertible Capital Securities or with respect to the delivery to any Agent Member, beneficial owner or other Person (other than the Depositary) of any notice (including any notice of
redemption) or the payment of any amount, under or with respect to such Contingent Convertible Capital Securities. All notices and communications to be given to the Holders and all payments to be made to Holders under the Contingent Convertible
Capital Securities and this Contingent Convertible Capital Securities Indenture shall be given or made only to or upon the order of the Holders (which shall be the Depositary or its nominee in the case of the Global Security). The rights of
beneficial owners in the Global Security shall be exercised only through the Depositary subject to the applicable procedures. The Company, the Trustee, the Paying Agent and the Contingent Convertible Capital Security Registrar shall be entitled to
rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its Agent Members and any beneficial owners. The Company, the Trustee, the Paying Agent and the Contingent Convertible Capital Security
Registrar shall be entitled to deal with the Depositary, and any nominee thereof, that is the Holder of any Global Security for all purposes of this Contingent Convertible Capital Securities Indenture relating to such Global Security (including the
payment of Liquidation Preference and Distributions and Additional Amounts, if any, and the giving of instructions or directions by or to the owner or holder of a beneficial ownership interest in such Global Security) as the sole Holder and shall
have no obligations to the beneficial owners thereof. None of the Company, the Trustee, the Paying Agent or the Contingent Convertible Capital Security Registrar shall have any responsibility or liability for any acts or omissions of the Depositary
with respect to such Global Security, for the records of any such Depositary, including records in respect of beneficial ownership interests in respect of any such Global Security, for any transactions between the Depositary and any Agent Member or
between or among the Depositary, any such Agent Member and/or any holder or owner of a beneficial interest in such Global Security, or for any transfers of beneficial interests in any such Global Security. 

Notwithstanding the foregoing, with respect to any Global Security, nothing herein shall prevent the Company, the Trustee, or any agent of the
Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by any Depositary (or its nominee), as a Holder, with respect to such Global Security or shall impair, as between such Depositary and
owners of beneficial interests in such Global Security, the operation of customary practices governing the exercise of the rights of such Depositary (or its nominee) as Holder of such Global Security. 

Each Holder and beneficial owner that acquires its Contingent Convertible Capital Security in the secondary market shall be deemed to
acknowledge and agree to be bound by and consent to the same provisions specified in this Contingent Convertible Capital Securities Indenture and the Contingent Convertible Capital Securities to the same extent as the Holders and beneficial owners
of the Contingent Convertible Capital Securities that acquire the Contingent Convertible Capital 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 Contingent Convertible Capital Securities, including, without limitation, in relation to Distribution cancellation, the Trigger Conversion, the Bail-in Power and the limitations on remedies
specified in the Contingent Convertible Capital Security and Section 6.03. 

  
 48 

 Section 3.13. Cancellation. All Contingent Convertible Capital Securities
surrendered for payment, redemption, registration of transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Company may at any time deliver to the
Trustee for cancellation any Contingent Convertible Capital Securities previously authenticated and delivered hereunder, and all Contingent Convertible Capital Securities so delivered shall be promptly cancelled by the Trustee. No Contingent
Convertible Capital Securities shall be authenticated in lieu of or in exchange for any Contingent Convertible Capital Securities cancelled as provided in this Section, except as expressly permitted by the provisions of the Contingent Convertible
Capital Securities of any series or pursuant to the provisions of this Contingent Convertible Capital Securities Indenture. The Trustee shall deliver to the Company all cancelled Contingent Convertible Capital Securities held by the Trustee. 

Section 3.14. Computation of Distributions. Except as otherwise specified pursuant to Section 3.01 for Contingent Convertible
Capital Securities of any series, Distributions on the Contingent Convertible Capital Securities of each series shall be computed on the basis of a 360-day year of twelve
30-day months. 
 Section 3.15. Cusip Numbers. The Company in issuing any series of
Contingent Convertible Capital Securities may use “CUSIP”, “ISIN” and/or “Common Code” and/or other similar numbers (if then generally in use) or any successor to such numbers and thereafter with respect to such series,
and, if so, the Trustee shall use “CUSIP”, “ISIN” and/or “Common Code” and/or other similar numbers or successor numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that
no representation is made as to the correctness of such numbers either as printed on the Contingent Convertible Capital Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers
printed on the Contingent Convertible Capital Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the “CUSIP”,
“ISIN” and/or “Common Code” and/or other similar numbers or successor numbers. 
 Section 3.16. Additional
Contingent Convertible Capital Securities. (a) The Company may without the consent or sanction of the Holders of the Contingent Convertible Capital Securities of any series: (i) take any action required to issue additional Parity
Securities or authorize, create and issue one or more other series of Parity Securities ranking equally with the Contingent Convertible Capital Securities of such series, as to the participation in the profits and/or assets of the Company, without
limit as to the amount; or (ii) take any action required to authorize, create and issue one or more other classes or series of shares of the Company or securities mandatorily convertible into Common Shares of the Company ranking junior to the
Contingent Convertible Capital Securities, as to the participation in the profits and/or assets of the Company. 
 (b) By acquiring a
Contingent Convertible Capital Securities, Holders of Contingent Convertible Capital Securities agree to renounce any rights of seniority or preference that may be conferred upon it (if any) under applicable Spanish law over any Holder of such other
Parity Securities issued by the Company from time to time. 
 (c) The Contingent Convertible Capital Securities do not grant the Holders of
the Contingent Convertible Capital Securities of such series pre-emption rights in respect of any possible future issues of Parity Securities or any other securities by the Company or any Subsidiary. 

  
 49 

 (d) The Company may, without the consent of the Holders of the Contingent Convertible
Capital Securities of any series, issue additional Contingent Convertible Capital Securities (“Additional Contingent Convertible Capital Securities”) of one or more of the series of Contingent Convertible Capital Securities issued
under this Contingent Convertible Capital Securities Indenture having the same ranking and same Distribution Rate, redemption terms and other terms as the Contingent Convertible Capital Securities of such series except for the price to the public,
original Distribution accrual date, issue date and first Distribution Payment Date. Any such Additional Contingent Convertible Capital Securities, together with the Contingent Convertible Capital Securities of the relevant series, will constitute a
single series of Contingent Convertible Capital Securities under this Contingent Convertible Capital Securities Indenture. 

Section 3.17. Correction of Minor Defects in or Amendment of Contingent Convertible Capital Securities. If, after issuance of any
Contingent Convertible Capital Security (including any Global Security), the Company or the Trustee shall become aware of any ambiguity, defect or inconsistency in any term of a Contingent Convertible Capital Security or Global Security, as the case
may be, or, with respect to any Contingent Convertible Capital Security (including any Global Security) issued on or after the date hereof, the Company and the Trustee agree to amend such Contingent Convertible Capital Security as contemplated by
Section 10.01, the parties hereto shall provide for the execution, authentication, delivery and dating of one or more replacement Contingent Convertible Capital Securities or Global Securities, as the case may be, pursuant to Section 3.03
hereto. 
 Section 3.18. Payments Subject to Fiscal Laws. All payments in respect of the Contingent Convertible Capital
Securities will be subject in all cases to any fiscal or other laws and regulations applicable thereto in the place of payment (including FATCA, any regulations or agreements thereunder, any official interpretation thereof, any intergovernmental
agreements with respect thereto, or any law implementing an intergovernmental agreement or any regulations or official interpretations relating thereto), but without prejudice to the provisions of Section 11.04. 

Section 3.19. Undertakings. So long as any Contingent Convertible Capital Security remains Outstanding, the Company shall, unless
approved by a majority in aggregate Liquidation Preference of such series: 
 (a) not make any issue, grant or distribution or take or omit
to take any other action if the effect thereof would be that, on Trigger Conversion, Common Shares could not, under any applicable law then in effect, be legally issued as fully paid; 

  
 50 

 (b) if any offer is made to all (or as nearly as may be practicable all) Shareholders (or
all (or as nearly as may be practicable all) such Shareholders other than the offeror and/or any associates of the offeror) to acquire all or a majority of the issued Common Shares, or if a scheme is proposed with regard to such acquisition (other
than a Newco Scheme), give notice of such offer or scheme to the Holders at the same time as any notice thereof is sent to the Shareholders (or as soon as practicable thereafter) that details concerning such offer or scheme may be obtained from the
specified offices of the Paying and Conversion Agents and, where such an offer or scheme has been recommended by the Board of Directors, or where such an offer has become or been declared unconditional in all respects or such scheme has become
effective, use all commercially reasonable endeavors to procure that a like offer or scheme is extended to the holders of any Common Shares issued during the period of the offer or scheme arising out of the Trigger Conversion; 

(c) in the event of a Newco Scheme, take (or shall procure that there is taken) all necessary action to ensure that such amendments are made
to this Contingent Convertible Capital Securities Indenture immediately after completion of the Scheme of Arrangement as are necessary to ensure that the Contingent Convertible Capital Securities may be converted into or exchanged for ordinary
shares in Newco (or depositary or other receipts or certificates representing ordinary shares of Newco) mutatis mutandis in accordance with and subject to this Contingent Convertible Capital Securities Indenture and the ordinary shares of
Newco are: 
 (i) admitted to the Relevant Stock Exchange; or 

(ii) listed and/or admitted to trading on another Recognized Stock Exchange, and the Holders of the Contingent Convertible
Capital Securities of the relevant series irrevocably authorize the Company to make such amendments to this Contingent Convertible Capital Securities Indenture without the need for any further authorization from the holders of the Contingent
Convertible Capital Securities of such series; 
 (d) issue, allot and deliver Common Shares upon Trigger Conversion subject to and as
provided in Section 4.01 below; 
 (e) use all reasonable endeavors to ensure that its issued and outstanding Common Shares and any
Common Shares issued upon Trigger Conversion will be admitted to listing and trading on the Relevant Stock Exchange or will be listed and/or admitted to trading on another Recognized Stock Exchange; 

(f) at all times keep in force the relevant resolutions needed for issue, free from pre-emptive rights, sufficient authorized but unissued
Common Shares to enable Trigger Conversion of the Contingent Convertible Capital Securities, and all rights of subscription and exchange for Common Shares, to be satisfied in full; and 

(g) where the provisions of Section 4.01 require or provide for a determination by an Independent Financial Adviser or a role to be
performed by a Settlement Shares Depository or a Paying and Conversion Agent, the Company shall use all reasonable endeavors promptly to appoint such persons for such purposes. 

  
 51 

 ARTICLE 4 

CONVERSION OF THE CONTINGENT CONVERTIBLE CAPITAL
SECURITIES 
 Section 4.01. Conversion upon Trigger Event. 

(a) If the Trigger Event occurs at any time on or after the issue date of any series of Contingent Convertible Capital Securities, then the
Company will: 
 (i) not declare or pay any Distribution on the Contingent Convertible Capital Securities of such series,
including any accrued and unpaid Distributions, which shall be cancelled by the Company in accordance with Section 3.08 and Section 3.09; and 

(ii) irrevocably and mandatorily (and without any requirement for the consent or approval of the Holders of Contingent
Convertible Capital Securities of such series) convert all the Contingent Convertible Capital Securities of such series into Common Shares (the “Trigger Conversion”) to be delivered on the relevant Conversion Settlement Date. If the
Trigger Event occurs, the Contingent Convertible Capital Securities of any series will be converted in whole and not in part. 
 (b) For the
purposes of the Company determining whether the Trigger Event has occurred, it will (i) calculate the CET1 ratio based on information (whether or not published) available to management of the Company, including information internally reported
within the Company pursuant to its procedures for ensuring effective ongoing monitoring of the capital ratios of the Company and the Group and (ii) calculate and publish the CET1 ratio on at least a quarterly basis. The Company’s or the
Regulator’s calculation shall be binding on the Trustee and the Holders of the relevant series of Contingent Convertible Capital Securities. 

(c) Subject as provided in this Section 4.01(c) with respect to fractions, the number of Conversion Shares shall be determined by
dividing the Liquidation Preference of such Contingent Convertible Capital Security by the relevant Conversion Price in effect on the relevant Trigger Event Notice Date. Fractions of Common Shares will not be issued on Trigger Conversion and no cash
payment or other adjustment will be made in lieu thereof. Without prejudice to the generality of the foregoing, if one or more Delivery Notices and the related Contingent Convertible Capital Securities are received by or on behalf of the Paying and
Conversion Agent such that the Conversion Shares or related ADSs to be delivered by or on behalf of the Settlement Shares Depository are to be registered in the same name or delivered to the same Clearing Agency participant account, the number of
such Conversion Shares to be delivered in respect thereof shall be calculated on the basis of the aggregate Liquidation Preference of such contingent convertible capital securities being so converted and rounded down to the nearest whole number of
Common Shares or related ADSs, as applicable. 

  
 52 

 (d) Upon any Trigger Event of any series of Contingent Convertible Capital Securities,
Holders shall have no claim against the Company in respect of (i) any Liquidation Preference of such series of Contingent Convertible Capital Securities or (ii) any accrued and unpaid Distributions cancelled or otherwise unpaid in respect
of Contingent Convertible Capital Securities of such series and the Contingent Convertible Capital Securities of such series shall cease to represent any right other than the right to receive Common Shares, if elected, or ADSs from or on behalf of
the Settlement Shares Depository. 
 (e) On the Conversion Settlement Date, the Company shall deliver to the Settlement Shares Depository
such number of Common Shares as is required to satisfy in full the Company’s obligation to deliver Common Shares in respect of the Trigger Conversion of the aggregate Liquidation Preference of Contingent Convertible Capital Securities of such
series Outstanding on the Trigger Event Notice Date. 
 (f) The obligation of the Company to issue and deliver Conversion Shares to a Holder
of Contingent Convertible Capital Securities of any series on the relevant Conversion Settlement Date shall be satisfied by the delivery of such Conversion Shares to the Settlement Shares Depository. Receipt of the relevant Conversion Shares by the
Settlement Shares Depository shall discharge the Company’s obligations in respect of such Contingent Convertible Capital Securities. 

(g) Holders of any series of Contingent Convertible Capital Securities shall have recourse to the Company only for the issue and delivery of
the relevant Conversion Shares to the Settlement Shares Depository. After such delivery, Holders of any series of Contingent Convertible Capital Securities shall have recourse to the Settlement Shares Depository only for the delivery to them of such
Conversion Shares or related ADSs, in the circumstances described in Section 4.06. 
 Section 4.02. Conversion Price. 

“Conversion Price” means, on the Trigger Event Notice Date, if the Common Shares are: 

(a) then admitted to trading on a Relevant Stock Exchange, the higher of: 

(i) the Current Market Price of a Common Share; 

(ii) the Floor Price; and 

(iii) the nominal value of a Common Share, in each case on the Trigger Event Notice Date; or 

(b) not then admitted to trading on a Relevant Stock Exchange, the higher of (ii) and (iii) above. 

  
 53 

 Section 4.03. Anti-Dilution Adjustment of the Floor Price. For the purposes of
this Section 4.03 only (a) references to the “issue” of Common Shares or Common Shares being issued shall, if not otherwise expressly specified in this Contingent Convertible Capital Securities Indenture, include the transfer
and/or delivery of Common Shares, whether newly issued and allotted or previously existing or held by or on behalf of the Company or any member of the Group, and (b) Common Shares held by or on behalf of the Company or any member of the Group
(and which, in the case of Section 4.03(a)(iv) and Section 4.03(a)(vi), do not rank for the relevant right or other entitlement) shall not be considered as or treated as in issue or issued or entitled to receive any Dividend, right or
other entitlement. 
 References to any issue or offer or grant to Shareholders or Existing Shareholders “as a class” or “by
way of rights” shall be taken to be references to an issue or offer or grant to all or substantially all Shareholders or Existing Shareholders, as the case may be, other than Shareholders or Existing Shareholders, as the case may be, to whom,
by reason of the laws of any territory or requirements of any recognized regulatory body or any other stock exchange or securities market in any territory or in connection with fractional entitlements, it is determined not to make such issue or
offer or grant. 
 (a) Upon the happening of any of the events described below and unless otherwise provided in the relevant prospectus
supplement, the Floor Price of any series of Contingent Convertible Capital Securities shall be adjusted as follows: 
 (i)
If and whenever there shall be a consolidation, reclassification/redesignation or subdivision affecting the number of Common Shares, the Floor Price shall be adjusted by multiplying the Floor Price in force immediately prior to such consolidation,
reclassification/redesignation or subdivision by the following fraction: 
 A 

B 
 where: 

 

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

  

	 	B	 is the aggregate number of Common 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. 

  
 54 

 (ii) If and whenever the Company shall issue any Common Shares credited as
fully paid to Shareholders by way of capitalization of profits or reserves (including any share premium account or capital redemption reserve) other than (i) where any such Common 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, (ii) where Shareholders may elect to receive a Cash Dividend in lieu of such Common Shares or (iii) where any such Common Shares are or are expressed to be
issued in lieu of a Dividend (whether or not a Cash Dividend equivalent or amount is announced or would otherwise be payable to Shareholders, whether at their election or otherwise), the Floor Price shall be adjusted by multiplying the Floor Price
in force immediately prior to such issue by the following fraction: 
 A 

B 
 where: 

 

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

 

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

Such adjustment shall become effective on the first day on which Common Shares are traded ex-rights on
the relevant Stock Exchange. 
 (iii) (A) If and whenever the Company shall pay any Extraordinary Dividend to its
shareholders, the Floor Price shall be adjusted by multiplying the Floor Price in force immediately prior to the Effective Date by the following fraction: 

A – B 
 A – C

 where: 
  

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

amount equal to the aggregate of the Fair Market Values of any previous Cash Dividends per Common Share paid or made in such Relevant Year (where C shall equal zero if such previous Cash Dividends per Common Share are equal to, or exceed, the
Reference Amount in respect of the Relevant Year). For the avoidance of doubt, “C” shall equal the Reference Amount determined in respect of the Relevant Dividend where no previous Cash Dividends per Common Share have been paid or made in
such Relevant Year. 

  
 55 

 Such adjustment shall become effective on the Effective Date or, if later, the first date
upon which the Fair Market Value of the relevant Extraordinary Dividend can be determined.

extraordinary dividend, extraordinary distribution, special dividend, special distribution or return of value to its shareholders or any analogous or similar term (including any distribution made as a result of any capital reduction), in which case
the Extraordinary Dividend shall be such Cash Dividend; or (ii) any Cash Dividend (the “Relevant Dividend”) paid or made in a financial year of the Company (the “Relevant Year”) if (A) the Fair Market Value of the
Relevant Dividend per Common Share or (B) the sum of (I) the Fair Market Value of the Relevant Dividend per Common Share and (II) an amount equal to the aggregate of the Fair Market Value or Fair Market Values of any other Cash
Dividend or Cash Dividends per Common Share paid or made in the Relevant Year (other than any Cash Dividend or part thereof previously determined to be an Extraordinary Dividend paid or made in such Relevant Year), exceeds the Reference Amount, and
in that case the Extraordinary Dividend shall be the amount by which the Reference Amount is so exceeded. 
 “Reference Amount”
means an amount per Ordinary Share that is consistent with the dividend policy of the Company as applied or to be applied for a period or projected period of at least three years. 

(B) If and whenever the Company shall pay or make any Non-Cash Dividend to
Shareholders, the Floor Price shall be adjusted by multiplying the Floor Price in force immediately prior to the Effective Date by the following fraction:

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

 

	 	B	 is the portion of the Fair Market Value of the aggregate Non-Cash
Dividend attributable to one Common Share, with such portion being determined by dividing the Fair Market Value of the aggregate Non-Cash Dividend by the number of Common Shares entitled to receive the
relevant Non-Cash Dividend (or, in the case of a purchase, redemption or buy back of Common Shares or any depositary or other receipts or certificates representing Common Shares by or on behalf of the Company
or any member of the Group, by the number of Common Shares in issue immediately following such purchase, redemption or buy back, and treating as not being in issue any Common Shares, or any Common Shares represented by depositary or other receipts
or certificates, purchased, redeemed or bought back).

as provided herein) or in the case of a Spin-Off, the first date on which the Common Shares are traded ex-the relevant Spin-Off
on the Relevant Stock Exchange. 
 (C) For the purposes of the above, Fair Market Value shall (subject as provided in
paragraph (a) of the definition of “Dividend” and in the definition of “Fair Market Value”) be determined as at the Effective Date. 

(D) In making any calculations for the purposes of this Section 4.03(c)(iii)Section 4.03(a)(iii), such adjustments (if

at such Current Market Price per Common Share; and 

  

	 	C	 is the number of Common Shares to be issued or, as the case may be, the maximum number of Common Shares which
may be issued upon exercise of such options, warrants or rights calculated as at the date of issue of such options, warrants or rights or upon conversion or exchange or exercise of rights of subscription or purchase or other rights of acquisition in
respect thereof at the initial conversion, exchange, subscription, purchase or acquisition price or rate,

acquisition of the Contingent Convertible Capital Securities of any series, each Holder and beneficial owner shall be deemed to have (i) agreed to all the terms and conditions of the Contingent Convertible Capital Securities of such series,
including, without limitation, those related to (x) Trigger Conversion following a Trigger Event and (y) the appointment of the Settlement Shares Depository, the issuance of the Settlement Shares to the Settlement Shares Depository (or to
the relevant recipient in accordance with the terms of the Contingent Convertible Capital Securities of such series), and acknowledged that such events in (x) and (y) may occur without any further action on the part of the Holders or beneficial
owner of the Contingent Convertible Capital Securities of such series or the Trustee, (ii) agreed that effective upon, and following, the Trigger Conversion, no amount shall be due and payable to the Holders of the Contingent Convertible
Capital Securities of such series, and the Company’s liability to pay any such amounts (including the Liquidation Preference of, or any Distribution in respect of, the Contingent Convertible Capital Securities of such series), except as noted
under Section 4.06 with respect to certain stamp and similar taxes, shall be automatically released, and the Holders shall not have the right to give a direction to the Trustee with respect to the Trigger Event and any related Trigger
Conversion, (iii) waived, to the extent permitted by the Trust Indenture Act, any claim against the Trustee arising out of its acceptance of its trusteeship under, and the performance of its duties, powers and rights in respect of, this
Contingent Convertible Capital Securities Indenture and in connection with the Contingent Convertible Capital Securities of such series, including, without limitation, claims related to or arising out of or in connection with a Trigger Event and/or
any Trigger Conversion and (iv) authorized, directed and requested DTC, the European Clearing Systems and any direct participant in DTC, the European Clearing Systems or other intermediary through which it holds such Contingent Convertible
Capital Securities to take any and all necessary action, if required, to implement the Trigger Conversion without any further action or direction on the part of such Holder of the Contingent Convertible Capital Securities of such series or the
Trustee.

 Section 4.06. Settlement Procedures. 

(a) Delivery of the Common Shares, or, if the Holder elects, ADSs, to the Holders of any series of Contingent Convertible Capital Securities
upon a Trigger Event shall be made in accordance with the procedures set forth in this Section 4.06, which remain subject to change to reflect changes in clearing system practices. 

(b) Holders of any series of Contingent Convertible Capital Securities cleared and settled through DTC may elect to have their Common Shares
delivered in the form of Common Shares or ADSs in accordance with the procedures set forth in this Section 4.06. The obligation to deliver ADSs if a Holder elects to have its Common Shares delivered in such form will apply only if at the time
of any Trigger Conversion the Company continues to maintain an ADS depositary facility. 
 (c) The Trigger Event Notice shall specify the
Suspension Date. On the Suspension Date, DTC shall suspend all clearance and settlement of transactions in the relevant series of Contingent Convertible Capital Securities. As a result, Holders of the Contingent Convertible Capital Securities of
such series will not be able to settle any transfers of any Contingent Convertible Capital Securities of such series following the Suspension Date, and any sale or other transfer of the Contingent Convertible Capital Securities of such series that a
Holder of the Contingent Convertible Capital Securities of such series may have initiated prior to the Suspension Date that is scheduled to settle after the Suspension Date will be rejected by DTC and will not be settled through DTC. The Contingent
Convertible Capital Securities of such series may cease to be admitted to trading on any stock exchange on which the Contingent Convertible Capital Securities of such series are then listed or admitted to trading after the Suspension Date. 

(d) On the Suspension Date, the Company shall deliver a notice in accordance with Section 1.06 to the Trustee and to the Holders of the
Contingent Convertible Capital Securities of the relevant series (a “Settlement Request Notice”) requesting that holders and beneficial owners of the Contingent Convertible Capital Securities of such series complete a notice to be
delivered to the Paying and Conversion Agent, with a copy to the Trustee (a “Delivery Notice”). The Settlement Request Notice shall specify (i) the date by which the Delivery Notice must be received by the Paying and Conversion
Agent (the “Notice Cut-off Date”) and (ii) the date on which the Contingent Convertible Capital Securities of such series in relation to which no Delivery Notice has been received by the
Paying and Conversion Agent on or before the Notice Cut-off Date shall be cancelled, which will be no more than twelve Business Days after the Conversion Settlement Date (the “Final Cancellation
Date”), as set forth in Section 4.07. 

  
 69 

 (e) In order to obtain delivery of the relevant Common Shares, or, if the Holder elects,
ADSs, a Holder or beneficial owner must deliver its Contingent Convertible Capital Securities and Delivery Notice to the Paying and Conversion Agent (including, the delivery of such Contingent Convertible Capital Securities and Delivery Notice to
the Paying and Conversion Agent through DTC) on or before the Notice Cut-off Date. If such delivery is made after the end of normal business hours at the specified office of the Paying and Conversion Agent, such delivery shall be deemed for all
purposes to have been made or given on the following Business Day. The Delivery Notice shall contain: (i) the name of the Holder or beneficial owner of the applicable series of Contingent Convertible Capital Securities; (ii) the aggregate
Liquidation Preference held by such Holder or beneficial owner of such series of Contingent Convertible Capital Securities on the date of such notice; (iii) the name in which the Common Shares or ADSs, as applicable, are to be registered, if
applicable (iv) whether Common Shares or ADSs are to be delivered to the Holder or beneficial owner of such series of Contingent Convertible Capital Securities; (v) the details of the DTC, Iberclear or other clearing system account
(subject to the limitations set out below) to which the ADSs or Common Shares are to be credited, details of the registered account in our ADS facility if direct registration ADSs are to be issued, or, if the Common Shares are not a participating
security in Iberclear or another clearing system, the address to which the Common Shares should be delivered; and (vi) such other details as may be required by the Paying and Conversion Agent. 

(f) The Delivery Notice must be given and the Contingent Convertible Capital Securities Delivered in accordance with the applicable procedures
of DTC (which may include the notice being given to the Paying and Conversion Agent by electronic means) and in a form acceptable to DTC and the Paying and Conversion Agent. 

(g) Subject to satisfaction of the requirements and limitations set forth in this Section 4.06 and provided the Delivery Notice is
delivered on or before the Notice Cut-off Date, the Paying and Conversion Agent shall give instructions to the Settlement Shares Depository that the Settlement Shares Depository shall deliver the relevant
Common Shares (rounded down to the nearest whole number of Common Shares) to, or shall deposit such relevant Common Shares with the ADS Depositary on behalf of, the Holder or beneficial owner of the relevant Contingent Convertible Capital Securities
completing the relevant Delivery Notice or its nominee in accordance with the instructions given in such Delivery Notice on the applicable Conversion Settlement Date. 

  
 70 

 (h) Any Delivery Notice shall be irrevocable. Failure properly to complete and deliver a
Delivery Notice and deliver the relevant Contingent Convertible Capital Securities may result in such Delivery Notice being treated as null and void and the Company shall be entitled to procure the sale of any applicable Common Shares to which the
relevant holder may be entitled in accordance with Section 4.06. Any determination as to whether any Delivery Notice has been properly completed and delivered as provided in this Section 4.06 shall be made by the Company in its sole
discretion, acting in good faith, and shall, in the absence of manifest error, be conclusive and binding on the relevant holders. 
 (i) A
Holder of the Contingent Convertible Capital Securities of any series or Selling Agent (as defined in Section 4.07) must pay (in the case of the Selling Agent by means of deduction from the net proceeds of sale set forth in Section 4.07)
any taxes and capital, stamp, issue and registration and transfer taxes or duties arising on Trigger Conversion (other than any taxes or capital, issue and registration and transfer taxes or stamp duties payable in Spain by the Company in respect of
the issue and delivery of the Common Shares in accordance with a Delivery Notice delivered pursuant to this Contingent Convertible Capital Securities Indenture which shall be paid by the Company) and such holder or the Selling Agent (as the case may
be) must pay (in the case of the Selling Agent, by way of deduction from the net proceeds of sale as aforesaid) all, if any, taxes arising by reference to any disposal or deemed disposal of a Contingent Convertible Capital Security or interest
therein. 
 (j) If the Company shall fail to pay any capital, stamp, issue, registration and transfer taxes and duties for which it is
responsible as provided above, the holder or Selling Agent, as the case may be, shall be entitled (but shall not be obliged) to tender and pay the same and the Company as a separate and independent obligation, undertakes to reimburse and indemnify
each holder or Selling Agent, as the case may be, in respect of any payment thereof and any penalties payable in respect thereof. 
 (k) The
Common Shares issued on Trigger Conversion will be fully paid and will in all respects rank pari passu with the fully paid Common Shares in issue on the Trigger Event Notice Date, except in any such case for any right excluded by mandatory
provisions of applicable law and except that such Common Shares will not rank for (or, as the case may be, the relevant holder shall not be entitled to receive) any rights, dividends or payments the record date or other due date for the
establishment of entitlement for which falls prior to the date that the resolution of issuance of the relevant Common Shares is approved. 

Section 4.07. Failure to Deliver a Delivery Notice. 

(a) If a duly completed Delivery Notice and the relevant Contingent Convertible Capital Securities are not delivered to a Paying and
Conversion Agent as provided in this Contingent Convertible Capital Securities Indenture on or before the Notice Cut-off Date, then at any time following the Notice
Cut-off Date and prior to the 10th Business Day after the Conversion Settlement Date, the Company may in its sole and absolute discretion (and the relevant Holders of such Contingent Convertible Capital
Securities shall be deemed to agree thereto), elect to appoint a person (the “Selling Agent”) to procure that all Common Shares held by the Settlement Shares Depository in respect of which the applicable Contingent Convertible Capital
Securities and completed Delivery Notice have not been delivered on or before the Notice Cut-off Date as aforesaid shall be sold by or on behalf of the Selling Agent as soon as reasonably practicable. 

  
 71 

 (b) If the applicable Contingent Convertible Capital Securities and Delivery Notice are not
delivered to the Paying and Conversion Agent on or before the Notice Cut-off Date, the Settlement Shares Depository shall continue to hold any Conversion Shares not sold by the Selling Agent until a Delivery
Notice is so delivered or the Final Cancellation Date, whichever is earlier. However, any Holder or beneficial owner of the Contingent Convertible Capital Securities delivering a Delivery Notice after the Notice
Cut-off Date will have to provide evidence of its entitlement to the relevant Common Shares, or if the holder elects, ADSs satisfactory to the Settlement Shares Depository in its sole and absolute discretion
in order to receive delivery of such Common Shares or ADSs (if so elected to be deposited with the ADS Depositary on its behalf). 
 (c)
Subject to the deduction by or on behalf of the Selling Agent of any amount payable in respect of its liability to taxation and the payment of any capital, stamp, issue, registration and/or transfer taxes and duties (if any) and any fees or costs
incurred by or on behalf of the Selling Agent in connection with the issue, allotment and sale thereof, and the conversion of any proceeds of such sale into U.S. dollars, the net proceeds of such sale, converted into U.S. dollars at the Prevailing
Rate on the Notice Cut-off Date, if necessary, shall as soon as reasonably practicable be distributed rateably to the relevant Holders in such manner and at such time as the Company shall determine and notify
to the relevant Holders. Such payment shall for all purposes discharge the obligations of the Company, the Settlement Shares Depository, the Paying and Conversion Agent and the Selling Agent to such Holders in respect of the Trigger Conversion. The
Company, the Settlement Shares Depository and the Selling Agent shall have no liability in respect of the exercise or non-exercise of any discretion or power pursuant to this Section 4.07 or in respect of
any sale of any Common Shares, whether for the timing of any such sale or the price at or manner in which any such Common Shares are sold or the inability to sell any such Common Shares. 

(d) If the Company does not appoint the Selling Agent by the 10th Business Day after the Conversion Settlement Date, or if any Common Shares
are not sold by the Selling Agent in accordance with this Section 4.07, Common Shares for which a Delivery Notice has not been received will be cancelled on the Final Cancellation Date. 

Section 4.08. Delivery of ADSs. In respect of any Conversion Shares that Holders elect to receive in the form of ADSs as specified
in the Delivery Notice, the Settlement Shares Depository shall deposit with the custodian for the ADS Depositary the number of Conversion Shares to be issued upon Trigger Conversion of the relevant series of Contingent Convertible Capital
Securities, and the ADS Depositary shall issue the corresponding number of ADSs to the DTC Participant account or registered ADS facility account specified by such Holders (per the
ADS-to-ordinary share ratio in effect on the Conversion Settlement Date). However, the issuance of the ADSs by the ADS Depositary may be delayed until the depositary
bank or the custodian receives confirmation that all required approvals have been given and that the Conversion Shares have been duly transferred to the custodian and that all applicable depositary fees and payments have been paid to the ADS
Depositary. 

  
 72 

 Section 4.09. Responsibility of Trustee, the Principal Paying Agent and the Paying
and Conversion Agent. The Trustee and any other Principal Paying Agent and Paying and Conversion Agent shall not at any time be under any duty or responsibility to any Holder to determine the Conversion Price (or any adjustment thereto) or
whether any facts exist that may require any adjustment (including any increase) of the Conversion Price, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or
in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Principal Paying Agent and Paying and Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any
shares of common stock, or of any securities, property or cash that may at any time be issued or delivered upon the conversion of any Contingent Convertible Capital Securities; and the Trustee and any other Principal Paying Agent and Paying and
Conversion Agent make no representations with respect thereto. Neither the Trustee nor any Principal Paying Agent and Paying and Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any shares of common
stock or stock certificates or other securities or property or cash upon the surrender of any Contingent Convertible Capital Securities for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company
contained in this Article. 
 ARTICLE 5 

SATISFACTION AND DISCHARGE 

Section 5.01. Satisfaction and Discharge of Contingent Convertible Capital Securities Indenture. This Contingent Convertible
Capital Securities Indenture shall upon Company Request cease to be of further effect with respect to the Contingent Convertible Capital Securities of any series (except as to any surviving rights of registration of transfer of the Contingent
Convertible Capital Securities herein expressly provided for), and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Contingent Convertible Capital Securities Indenture with
respect to the Contingent Convertible Capital Securities of any series when: 
 (a) all Contingent Convertible Capital Securities of such
series theretofore authenticated and delivered (other than Contingent Convertible Capital Securities which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 3.06) have been delivered to the Trustee
for cancellation; 
 (b) the Company has paid or caused to be paid all other sums payable hereunder (including Accrued Distributions, if
any) by the Company with respect to the Contingent Convertible Capital Securities of such series; and 
 (c) the Company has delivered to
the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Contingent Convertible Capital Securities Indenture with respect
to the Contingent Convertible Capital Securities of such series have been complied with. 

  
 73 

 In addition, upon the exercise of a Bail-in Power
with respect to a series of Contingent Convertible Capital Securities which results in the cancellation, or the conversion into other securities, of all the Liquidation Preference of, and Distributions on such Contingent Convertible Capital
Securities or such Contingent Convertible Capital Securities otherwise ceasing to be Outstanding, this Contingent Convertible Capital Securities Indenture shall be satisfied and discharged as to such series. 

Notwithstanding any satisfaction and discharge of this Contingent Convertible Capital Securities Indenture, the obligations of the Company to
the Trustee under Section 7.08 of this Contingent Convertible Capital Securities Indenture, the obligations of the Trustee to any Authenticating Agent under Section 7.15 of this Contingent Convertible Capital Securities Indenture and the
obligations of the Trustee under Section 5.02 of this Contingent Convertible Capital Securities Indenture and the last paragraph of Section 11.03 of this Contingent Convertible Capital Securities Indenture shall survive such satisfaction
and discharge. 
 Section 5.02. Application of Trust Money. Subject to the provisions of the last paragraph of
Section 11.03, all cash deposited with the Trustee pursuant to Section 5.01 shall be held in trust and such cash shall be applied by it, in accordance with the provisions of the Contingent Convertible Capital Securities of such series and
this Contingent Convertible Capital Securities Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the Liquidation
Preference and accrued but unpaid Distributions, if any, for the payment of which such cash has been deposited with the Trustee. 

Section 5.03. Repayment to Company. The Trustee, the Calculation Agent and any Paying Agent promptly shall pay to the Company upon
Company Request any excess money held by them at any time with respect to any series of Contingent Convertible Capital Securities. 

Section 5.04. Reinstatement. If the Trustee or any Paying Agent is unable to apply any money or U.S. Government Obligations in
accordance with this Article 5 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the obligations of the Company under this
Contingent Convertible Capital Securities Indenture, the Contingent Convertible Capital Securities shall be revived and reinstated as though no deposit had occurred pursuant to this Article 5 until such time as the Trustee or such Paying Agent is
permitted to apply all such money or U.S. Government Obligations in accordance with this Article 5; provided, however, that, if the Company has made any payment of Liquidation Preference of or Distributions on any Contingent Convertible Capital
Securities because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Contingent Convertible Capital Securities to receive such payment from the money or U.S. Government Obligations held by
the Trustee or such Paying Agent. 

  
 74 

 ARTICLE 6 

REMEDIES 

Section 6.01. Enforcement Events. 

(a) Each of the following events is an “Enforcement Event” with respect to any series of Contingent Convertible Capital Securities:

 (i) non-payment of Redemption Price on such series when due as set forth in Section 12.04;

 (ii) the breach of any term, obligation or condition binding on the Company under the Contingent Convertible Capital Securities of such
series (other than any of the Company’s payment obligations under or arising from the Contingent Convertible Capital Securities of such series, including payment of any Liquidation Preference or Distributions, including any damages awarded for
breach of any obligations) (a “Performance Obligation”); or 
 (iii) the occurrence of any voluntary or involuntary
liquidation of the Company (a “Liquidation Event”) prior to the occurrence of a Trigger Event. 
 (b) Neither a
cancellation of Contingent Convertible Capital Securities of any series, a reduction, in part or in full, of the Amounts Due on Contingent Convertible Capital Securities of any series, the conversion thereof into another security or obligation of
the Company or another person, in each case as a result of the exercise of the Bail-in Power by the Relevant Resolution Authority with respect to the Company, nor the exercise of any Bail-on Power by the Relevant Resolution Authority with respect to such Contingent Convertible Capital Securities will be an Enforcement Event or otherwise constitute
non-performance of a contractual obligation, or entitle the holders of such securities to any remedies, which are hereby expressly waived. 

(c) In addition, the Trigger Conversion will not constitute an Enforcement Event or the occurrence of any event related to the insolvency of
the Company or entitle Holders to take any action to cause the dissolution, liquidation or winding up of the Company. 
 Section 6.02.
Liquidation Distribution. (a) Subject as provided in Section 6.02(b) below, in the event of any Liquidation Event, Holders of the Contingent Convertible Capital Securities of any series (unless previously converted into Common
Shares pursuant to Section 4.01) shall be entitled to receive out of the assets of the Company available for distribution to Holders of such series, the Liquidation Distribution. Such entitlement will arise before any distribution of assets is
made to Holders of Common Shares or any other instrument of the Company ranking junior to the Contingent Convertible Capital Securities of such series. 

  
 75 

 (b) If, before the occurrence of a Liquidation Event, the Trigger Event occurs but the
relevant conversion of the Contingent Convertible Capital Securities of such series into Common Shares pursuant to Section 4.01 is still to take place, Holders of the Contingent convertible Capital Securities of such series will be entitled to
receive out of the relevant assets of the Company a monetary amount equal to that which holders of such Contingent Convertible Capital Securities of such series would have received on any distribution of the assets of the Company if such conversion
had taken place immediately prior to such liquidation. 
 (c) After payment of the relevant entitlement in respect of a Contingent
Convertible Capital Security as described in this Section 6.02, such Contingent Convertible Capital Security will confer no further right or claim to any of the remaining assets of the Company. 

Section 6.03. Limitation of Remedies Upon an Enforcement Event. 

The sole remedies of the holders of the Contingent Convertible Capital Securities of a series and the Trustee under the Contingent Convertible
Capital Securities of such series upon the occurrence of an Enforcement Event shall be: 
 (a) to seek enforcement of the Company’s
obligation to pay the Redemption Price of the securities of such series if not paid within 14 days of the date fixed for redemption (provided that the applicable conditions described under Section 12.04 shall have been satisfied); 

(b) to seek enforcement of a Performance Obligation; and 

(c) to enforce the entitlement set forth in Section 6.02. 

The foregoing shall not prevent the holders of the Contingent Convertible Capital Securities of such series or the Trustee from instituting
proceedings for the bankruptcy of Banco Santander. 
 Section 6.04. No Other Remedies and Other Terms. 

(a) Other than the limited remedies specified in this Article 6, and subject to paragraph (c) below, no remedy against the Company shall
be available to the Trustee (acting on behalf of the Holders) or to the Holders of the Contingent Convertible Capital Securities of any series, whether for the recovery of amounts owing in respect of such Contingent Convertible Capital Securities
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 Contingent Convertible Capital Securities in relation thereto; provided, however, that the Company’s
obligations to the Trustee under, and the Trustee’s lien provided for in Section 7.08 of the Contingent Convertible Securities Indenture and the Trustee’s rights to have money collected applied first to pay amounts due to it under
such Section pursuant to Section 6.08 of the Contingent Convertible Securities Indenture shall not be limited or impaired by this Article 6 or otherwise and expressly survive any Enforcement Event and are not subject to the subordination
provisions of Section 13.01. 

  
 76 

 (b) Notwithstanding the limitations on remedies specified in this Article 6, (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 under the provisions of this Contingent Convertible Capital Securities Indenture, and (ii) nothing shall impair
the right of a Holder of the Contingent Convertible Capital Securities under the Trust Indenture Act, absent such Holder’s consent, to sue for any payment due but unpaid with respect to the Contingent Convertible Capital Securities as provided
for in Section 6.10; provided that, in the case of (i) and (ii) above, any payments in respect of, or arising from, the Contingent Convertible Capital Securities, including any payments or amounts resulting or arising from the enforcement
of any rights under the Trust Indenture Act in respect of the Contingent Convertible Capital Securities, shall be subject to the subordination provisions set forth in Section 13.01. 

(c) In furtherance of Section 7.01 of this Contingent Convertible Capital Securities Indenture: 

(i) For purposes of Sections 315(a) and 315(c) of the Trust Indenture Act, the term “default” is hereby defined to
mean an Enforcement Event which has occurred and is continuing. 
 (ii) Notwithstanding anything contained in this Contingent
Convertible Capital Securities Indenture to the contrary, the duties and responsibilities of the Trustee under this Contingent Convertible Capital Securities Indenture shall be subject to the protections, exculpations and limitations on liability
afforded to an indenture trustee under the provisions of the Trust Indenture Act. 
 Section 6.05. Agreement with Respect to
Limitation of Remedies for Breach of a Performance Obligation. By its acquisition of the Contingent Convertible Capital Securities of any series, each Holder and beneficial owner of the Contingent Convertible Capital Securities of such series
acknowledges and agrees that such Holder and beneficial owner will not seek, and will not direct the Trustee to seek, a claim for damages against the Company in respect of a breach by the Company of a Performance Obligation and that the sole and
exclusive remedy that such Holder and the Trustee may seek under the Contingent Convertible Capital Securities of such series and this Contingent Convertible Capital Securities Indenture for a breach by the Company of a Performance Obligation is
specific performance. 
 Section 6.06. Trustee May File Proofs of Claim. In case of the pendency of any receivership,
insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition, winding-up or other judicial proceeding relative to the Company or any other obligor upon the Contingent Convertible
Capital Securities of any series or to the property of the Company or such other obligor or their creditors (other than under or in connection with a scheme of amalgamation or reconstruction not involving bankruptcy or insolvency), the Trustee
(irrespective of whether the Liquidation Preference of the Contingent Convertible Capital Securities of such series shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have
made any demand on the Company for the payment of overdue Liquidation Preference or Distributions) shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act
in order to have claims of the Holders and the Trustee allowed in any such proceeding; provided that the Company shall not, as a result of the bringing of such proceedings, be obliged to pay any sum representing or measured by reference to
Liquidation Preference or Distributions on the Contingent Convertible Capital Securities sooner than the same would otherwise have been payable by it. In particular, the Trustee shall be authorized to collect and receive any moneys and other
property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder of
a Contingent Convertible Capital Security to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to such Holders or holders, to first pay to the Trustee any amount due to it for
the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due to the Trustee under Section 7.08. 

  
 77 

 Subject to Article 9 and Section 10.02, nothing herein contained shall be deemed to
authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder of any Contingent Convertible Capital Security any plan of reorganization, arrangement, adjustment, or composition affecting any Contingent Convertible
Capital Securities or the rights of any Holder of any Contingent Convertible Capital Security or to authorize the Trustee to vote in respect of the claim of any such Holder in any such proceeding. 

The provisions of this Section 6.06 are subject to the provisions of Section 13.01. 

Section 6.07. Trustee May Enforce Claims Without Possession of Contingent Convertible Capital Securities. All rights of action and
claims under this Contingent Convertible Capital Securities Indenture or the Contingent Convertible Capital Securities, if any, may be prosecuted and enforced by the Trustee without the possession of any of the Contingent Convertible Capital
Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the
payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel (subject, with regard to the Company, to the provisions of Article 13) be for the ratable benefit of the Holders of the Contingent
Convertible Capital Securities in respect of which such judgment has been recovered. 
 Section 6.08. Application of Money
Collected. Any money collected by the Trustee pursuant to this Article or, after an Enforcement Event, any money or other property distributable in respect of the Company’s obligations under this Contingent Convertible Capital Securities
Indenture, in respect of any series of Contingent Convertible Capital Securities shall, subject to the provisions of Section 13.02 in relation to waiver of set-off and to Section 13.01 in relation to
the subordination of the Contingent Convertible Capital Securities, be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of Liquidation Preference or Distributions
upon presentation of such Contingent Convertible Capital Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: 

  
 78 

 FIRST: To the payment of all amounts applicable to such series of Contingent Convertible
Capital Securities in respect of which or for the benefit of which such money has been collected and due and owing to the Trustee (including any predecessor Trustee) under Section 7.08;

Convertible Capital Securities in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Contingent Convertible Capital
Securities for Liquidation Preference and Distributions, if any, respectively; and 
 THIRD: To the payment of the balance, if any, to the
Company. 
 Section 6.09. Limitation on Suits. No Holder of any Contingent Convertible Capital Security of any series shall have
any right to institute any proceeding, judicial or otherwise, with respect to this Contingent Convertible Capital Securities 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 Enforcement Event with respect to Contingent Convertible
Capital Securities of the same series specifying such Enforcement Event and stating that such notice is a “Notice of Enforcement Event” hereunder; 

(b) the Holders of not less than 25% in aggregate Liquidation Preference of the Outstanding Contingent Convertible Capital Securities of such
series shall have made written request to the Trustee to institute proceedings in respect of such Enforcement Event in its own name, as Trustee hereunder; 

(c) such Holder of a Contingent Convertible Capital Security has offered to the Trustee reasonable indemnity satisfactory to it (as determined
by the Trustee in its sole discretion) against the costs, expenses and liabilities to be incurred in compliance with such request; 
 (d)
the Trustee for 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
60-day period by the Holders of a majority in Liquidation Preference of the Outstanding Contingent Convertible Capital Securities of such series; 

  
 79 

 it being understood and intended that no one or more Holders of Contingent Convertible Capital Securities of
a particular series shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Contingent Convertible Capital Securities 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 this Contingent Convertible Capital Securities Indenture, except in the manner herein provided and for the equal
and ratable benefit of all Holders of Contingent Convertible Capital Securities of such series.

of Holders to Receive Liquidation Preference and Distributions. Notwithstanding any other provision in this Contingent Convertible Capital Securities Indenture, and subject to Article 13 in relation to the subordination of the Contingent
Convertible Capital Securities of any series, the Holder of any Contingent Convertible Capital Security shall have the right, which is absolute and unconditional, to receive payment of the Liquidation Preference of and any Distribution on such
Contingent Convertible Capital Security when due and payable in accordance with the provisions of this Contingent Convertible Capital Securities Indenture (including Article 3 and Article 14 hereof) and as expressed in such Contingent Convertible
Capital Security (or, in the case of redemption, on the Redemption Date, as the case may be) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder. 

Section 6.11. Restoration of Rights and Remedies. If the Trustee or any Holder of any Contingent Convertible Capital Security has
instituted any proceeding to enforce any right or remedy under this Contingent Convertible Capital Securities Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such
Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders of Contingent Convertible Capital Securities shall be restored severally and respectively to their former positions
hereunder and thereafter all rights and remedies of the Trustee and the Holders of Contingent Convertible Capital Securities shall continue as though no such proceeding had been instituted. 

Section 6.12. Rights and Remedies Cumulative. Subject to the limitations on remedies provided for in this Article 6, except as
otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Contingent Convertible Capital Securities in the last paragraph of Section 3.06, no right or remedy herein conferred upon or reserved to the
Trustee or to the Holders of Contingent Convertible Capital Securities is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right
or remedy. 
 Section 6.13. Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Contingent
Convertible Capital Security to exercise any right or remedy accruing upon any Enforcement Event shall impair any such right or remedy or constitute a waiver of any such Enforcement Event or an acquiescence therein. Every right and remedy given by
this Article or by law to the Trustee or to the Holders of Contingent Convertible Capital Securities may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders of Contingent Convertible Capital
Securities.

Liquidation Preference of the Outstanding Contingent Convertible Capital Securities of any series 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 Contingent Convertible Capital Securities of such series, provided that 
 (a) such
direction shall not be in conflict with any rule of law or with this Contingent Convertible Capital Securities Indenture or with the Contingent Convertible Capital Securities of any series; 

(b) the Trustee shall not determine that the action so directed would be unjustly prejudicial to the Holders of any Contingent Convertible
Capital Securities of any series not taking part in such direction with respect to which the Trustee is acting as the Trustee; and

the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. 
 Section 6.15.
Undertaking for Costs. All parties to this Contingent Convertible Capital Securities Indenture agree, and each Holder of any Contingent Convertible Capital Security by his acceptance thereof shall be deemed to have agreed, that any court may
in its discretion require, in any suit for the enforcement of any right or remedy under this Contingent Convertible Capital Securities Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, the
filing by any party litigant to such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such
suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder or group of
Holders holding in the aggregate more than 10% in Liquidation Preference of the Outstanding Contingent Convertible Capital Securities of any series, or to any suit instituted by any Holder for the enforcement of the payment of the Liquidation
Preference of or Distributions on any Contingent Convertible Capital Security on or after the dates upon which such Distributions become due and payable pursuant to the terms hereof or the terms expressed in such Contingent Convertible Capital
Security (or, in the case of redemption on or after the Redemption Date). 
 Section 6.16. Waiver of Past Enforcement Events.

(i) any past Enforcement Event that results from a Liquidation Event and (ii) any Enforcement Event in respect of a covenant or provision hereof which under Article 10 cannot be modified or amended without the consent of the Holder of each
Outstanding Contingent Convertible Capital Security of such series affected. 

  
 81 

 (b) Upon the occurrence of any waiver permitted by paragraph (a) above, such
Enforcement Event shall cease to exist, and any Enforcement Event with respect to this Contingent Convertible Capital Securities arising therefrom shall be deemed to have been cured and not to have occurred for every purpose of the Contingent
Convertible Capital Securities Indenture, but no such waiver shall extend to any subsequent or other Enforcement Event or impair any right consequent thereon. 

ARTICLE 7 
 THE
TRUSTEE 
 Section 7.01. Certain Duties and Responsibilities. 

(a) Except during the continuance of an Enforcement Event, 

(i) the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Contingent
Convertible Capital Securities Indenture, and no implied covenants or obligations shall be read into this Contingent Convertible Capital Securities Indenture against the Trustee; and 

(ii) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the
correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Contingent Convertible Capital Securities Indenture; but in the case of any such certificates or
opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Contingent Convertible
Capital Securities Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts, statements, opinions or conclusions stated therein). 

(b) In case an Enforcement Event has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this
Contingent Convertible Capital Securities 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. 

  
 82 

 (c) No provision of this Contingent Convertible Capital Securities Indenture shall be
construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that 

(i) this Section 7.01(c) shall not be construed to limit the effect of subsections (a) or (d) of this Section; 

(ii) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it shall be
proved that the Trustee was negligent in ascertaining the pertinent facts; and 
 (iii) the Trustee shall not be liable with
respect to any action taken, suffered or omitted to be taken by it in good faith in accordance with the direction of the Holders of a majority in Liquidation Preference of the Outstanding Contingent Convertible Capital Securities of any series,
determined as provided herein, relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Contingent Convertible Capital
Securities Indenture with respect to the Contingent Convertible Capital Securities of such series; 
 (d) No provision of this Contingent
Convertible Capital Securities Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it
shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it; and 

(e) Whether or not therein expressly so provided, every provision of this Contingent Convertible Capital Securities Indenture relating to the
conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section. 

Section 7.02. Spanish Tax Procedures and Obligations of the Trustee. In connection with each payment made on any Payment Date (as
defined in Appendix 1 attached hereto) in respect of the issued Contingent Convertible Capital Securities hereunder, the Trustee or Paying Agent shall comply with the tax procedures set forth in Appendix 1 hereto. The Trustee or Paying Agent shall
have no duty or responsibility to comply with other Spanish tax obligations arising out of this Contingent Convertible Capital Securities Indenture. The Company shall be responsible for the payment of any and all amounts due under the Contingent
Convertible Capital Securities. Therefore, the Trustee or Paying Agent shall not be liable for any amounts owed to any person due to its failure to properly comply with the tax procedures referred to in this Section 7.02 and Appendix 1 hereto,
except such as may result from the negligence, willful misconduct or fraud of the Trustee or Paying Agent or any of its agents or employees. The Trustee or Paying Agent may request and rely conclusively upon any instructions from the Company in
respect of any action necessary or required to be taken by the Trustee or Paying Agent pursuant to this Section 7.02 and Appendix 1 hereto; provided, however, that in no event shall the Trustee or Paying Agent be required to expend or risk its
own funds in the performance of any of its duties pursuant to this Section 7.02 and Appendix 1 hereto, or be obligated to take any legal or other action which might in its judgment involve or cause it to incur any expense or liability unless it
shall have been furnished with acceptable indemnification and security.

of any Enforcement Event hereunder with respect to Contingent Convertible Capital Securities of any series of which a Responsible Officer of the Trustee has received written notice the Trustee shall transmit in the manner and to the extent provided
in Section 1.06 to Holders of Contingent Convertible Capital Securities of such series notice of such Enforcement Event hereunder of which the Trustee has received written notice, unless such Enforcement Event shall have been cured or waived;
provided, however, that, the Trustee shall be protected in withholding such notice if it determines in good faith that the withholding of such notice is in the interest of the Holders of Contingent Convertible Capital Securities of such series. 

Section 7.04. Certain Rights of Trustee. Subject to the provisions of Section 7.01: 

(a) the Trustee may conclusively rely and shall be fully protected in acting or refraining from acting upon any resolution, Officer’s

 84 

 (f) the Trustee shall not be bound to make any investigation into the facts or matters
stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, coupon or other evidence of indebtedness or other paper or document, but the Trustee, in its
discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and
premises of the Company, personally or by agent or attorney at the sole reasonable cost and expense of the Company and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation; provided that the Trustee

of whether the claim for loss or damage is made in negligence or otherwise; 
 (j) the Trustee shall not be liable for any action taken,
suffered, or omitted to be taken by it in good faith and reasonably believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Contingent Convertible Capital Securities Indenture, unless it shall be proved
that the Trustee was negligent in ascertaining the pertinent facts; 
 (k) the Trustee shall not be deemed to have notice of any Enforcement
Event unless a Responsible Officer of the Trustee has received, at the Corporate Trust Office of the Trustee, written notice of such an Enforcement Event and such notice references the Contingent Convertible Capital Securities and/or this Contingent
Convertible Capital Securities Indenture; 
 (l) the rights, privileges, protections, immunities and benefits given to the Trustee,
including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act hereunder; 

  
 85 

 (m) the Trustee may request that the Company deliver a certificate setting forth the names
of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Contingent Convertible Capital Securities Indenture, which certificate may be signed by any person authorized to sign an Officer’s

and in the Contingent Convertible Capital Securities, except the Trustee’s certificates of authentication, shall be taken as the statements of the Company, and neither the Trustee nor any Authenticating Agent assumes any responsibility for
their correctness. The Trustee makes no representations as to the validity or sufficiency of this Contingent Convertible Capital Securities Indenture or of the Contingent Convertible Capital Securities, except that the Trustee represents and
warrants that it has duly authorized, executed and delivered this Contingent Convertible Capital Securities Indenture. Neither the Trustee nor any Authenticating Agent shall be accountable for the use or application by the Company of Contingent
Convertible Capital Securities or the proceeds thereof. The Trustee shall not be responsible to make any calculation with respect to any matter under this Contingent Convertible Capital Securities Indenture other than as specifically provided for
herein. The Trustee shall have no duty to monitor or investigate the Company’s compliance with or the breach of, or cause to be performed or observed, any representation, warranty, or covenant, or agreement of any Person, other than the
Trustee, made in this Contingent Convertible Capital Securities Indenture 
 No provision of this Contingent Convertible Capital Securities
Indenture shall be deemed to impose any duty or obligation on the Trustee to perform any act or acts, receive or obtain any interest in property or exercise any interest in property, or exercise any right, power, duty or obligation conferred or
imposed on it in any jurisdiction in which it shall be illegal, or would subject the Trustee to taxation or other consequences that, in the sole determination of the Trustee, are adverse to the Trustee, or in which the Trustee shall be unqualified
or incompetent in accordance with applicable law to perform any such act or acts, to receive or obtain any such interest in property or to exercise any such right, power, duty or obligation. 

Section 7.06. May Hold Contingent Convertible Capital Securities. The Trustee, any Authenticating Agent, any Paying Agent, any
Contingent Convertible Capital Security Registrar and any Calculation Agent or any other agent of the Company, in its individual or any other capacity, may become the owner or pledgee of Contingent Convertible Capital Securities and, subject to
Section 7.11 and Section 7.15, may otherwise deal with the Company with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Contingent Convertible Capital Security Registrar, Calculation Agent or such
other agent. 

  
 86 

 Section 7.07. Money Held in Trust. Money held by the Trustee in trust hereunder
need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on or to invest any money received by it hereunder except as otherwise agreed with the Company. 

Section 7.08. Compensation and Reimbursement. The Company agrees 

(a) to pay to the Trustee from time to time compensation for all services rendered by it hereunder as agreed upon in writing by the Company
from time to time (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust); 

(b) except as otherwise expressly provided herein, to reimburse the Trustee for all reasonable expenses, disbursements and advances incurred
or made by the Trustee in accordance with any provision of this Contingent Convertible Capital Securities Indenture (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except any such expense,
disbursement or advance as shall be determined by a court of competent jurisdiction to have been caused by its own negligence or bad faith; and 

(c) to indemnify the Trustee (which for purposes of this subsection (c) shall be deemed to include its directors, officers, employees and
agents) or any predecessor Trustee for, and to hold it harmless against, any and all loss, liability, claim, damage or expense (including legal fees and expenses) and taxes (other than taxes based upon, measured by or determined by the income of the
Trustee) incurred without negligence or bad faith on its part, arising out of or in connection with the acceptance or administration of the trust or trusts hereunder including the costs and expenses of defending itself against any claim (whether
asserted by the Company, or any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, or in connection with enforcing the provisions of this Section, but excluding any tax
liabilities of the Trustee in respect of its income. 
 In addition to, but without prejudice to its other rights under this Contingent
Convertible Capital Securities Indenture, when the Trustee incurs expenses or renders services in connection with an Enforcement Event specified in Section 6.01, the fees, costs and expenses (including the charges and expenses of its counsel)
and the compensation for the services are intended to constitute expenses of administration under any applicable federal or state bankruptcy, insolvency or other similar law. 

  
 87 

 The Trustee shall notify the Company in writing of the commencement of any action or claim
in respect of which indemnification may be sought promptly after a Responsible Officer of the Trustee becomes aware of such commencement (provided that the failure to make such notification shall not affect the Trustee’s rights hereunder) and
the Company shall be entitled to participate in, and to the extent it shall wish, to assume the defense thereof, including the employment of counsel reasonably satisfactory to the Trustee. If the Company and the Trustee are being represented by the
same counsel and the Company has assumed the defense of the claim, the Trustee shall not be authorized to settle a claim without the written consent of the Company, which consent shall not be unreasonably withheld. 

As security for the performance of the obligations of the Company under this Section, the Trustee shall have a senior lien to which the
Contingent Convertible Capital Securities are hereby made subordinate, upon all property and funds held or collected by the Trustee as such, except funds held in trust for the payment of Liquidation Preference or Distributions on the Contingent
Convertible Capital Securities. 
 “Trustee” for purposes of this Section shall include any predecessor Trustee; provided,
however, that the negligence, willful misconduct or bad faith of any Trustee hereunder shall not affect the rights of any other Trustee hereunder. 

The Trustee’s rights to payment of its fees, reimbursement and indemnity under, and its lien provided for in, this Section 7.08
shall survive the payment in full of the Contingent Convertible Capital Securities, the satisfaction and discharge of this Contingent Convertible Capital Securities Indenture, the resignation or removal of the Trustee, the termination for any reason
of this Contingent Convertible Capital Securities Indenture and the exercise of the Bail-in Power and the other relevant resolution tools by the Relevant Resolution Authority. 

Section 7.09. Disqualification; Conflicting Interests. If the Trustee has or shall acquire a conflicting interest within the
meaning of Section 310(b) of the Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, Section 310(b) of the Trust Indenture Act and
this Contingent Convertible Capital Securities Indenture. 
 Section 7.10. Corporate Trustee Required; Eligibility. There shall
at all times be a Trustee hereunder with respect to each series which shall be a Person organized and doing business under the laws of the United States of America, any State thereof or the District of Columbia, authorized under such laws to
exercise corporate trust powers, having a combined capital and surplus of at least $50,000,000, subject to supervision or examination by Federal or State or District of Columbia authority and having a corporate trust office or agency in the Borough
of Manhattan, The City of New York, New York. If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined
capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of
this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article 7. 

  
 88 

 Section 7.11. Resignation and Removal; Appointment of Successor.

the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 7.12. 
 (b) The
Trustee may resign at any time with respect to the Contingent Convertible Capital Securities of one or more series by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 7.12
shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the
Contingent Convertible Capital Securities of such series. 
 (c) The Trustee may be removed at any time with respect to the Contingent
Convertible Capital Securities of any series by Act of the Holders of a majority in Liquidation Preference of the Outstanding Contingent Convertible Capital Securities of such series delivered to the Trustee and to the Company. If the instrument of
acceptance by a successor Trustee required by Section 7.12 shall not have been delivered to the Trustee within 30 days after the giving of such notice of removal, the Trustee may petition at the expense of the Company any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the Contingent Convertible Capital Securities of such series. 
 (d)
If at any time: 
 (i) the Trustee shall fail to comply with Section 7.09 after written request therefor by the Company
or by any Holder who has been a bona fide Holder of a Contingent Convertible Capital Security of the series as to which the Trustee has a conflicting interest for at least six months, or 

(ii) the Trustee shall cease to be eligible under Section 7.10 and shall fail to resign after written request therefor by
the Company or by any Holder who has been a bona fide Holder of a Contingent Convertible Capital Security for at least six months, or 

(iii) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or
of its property shall be appointed or any public officer shall take charge, or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, or 

(iv) the Trustee shall fail to perform its obligations to the Company under this Contingent Convertible Capital Securities
Indenture in any material respect, 

  
 89 

 then, in any such case, (i) the Company by a Board Resolution may remove the Trustee with respect to
any or all series of Contingent Convertible Capital Securities or (ii) subject to Section 6.15 (and except in the case of subparagraph (d)(iv) above), any Holder who has been a bona fide Holder of a Contingent Convertible Capital Security for
at least six months (and, in the case of (i) above, who is a Holder of a Contingent Convertible Capital Security of the series as to which the Trustee has a conflicting interest) may, on behalf of himself and all others similarly situated,
petition any court of competent jurisdiction for the removal of the Trustee with respect to all Contingent Convertible Capital Securities and the appointment of a successor Trustee or Trustees. 

(e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause,
with respect to the Contingent Convertible Capital Securities of one or more series, the Company, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the Contingent Convertible Capital Securities of such
series (it being understood that any successor Trustee may be appointed with respect to the Contingent Convertible Capital Securities of one or more or all of such series and at any time there shall be only one Trustee with respect to the Contingent
Convertible Capital Securities of any particular series), and shall comply with the applicable requirements of Section 7.12. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor
Trustee with respect to the Contingent Convertible Capital Securities of any series shall be appointed by Act of the Holders of a majority in Liquidation Preference of the Outstanding Contingent Convertible Capital Securities of such series
delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 7.12, become the successor Trustee with
respect to the Contingent Convertible Capital Securities of such series and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to the Contingent Convertible Capital Securities of any series
shall have been so appointed by the Company or the Holders of Contingent Convertible Capital Securities of such series and accepted appointment in the manner hereinafter required by Section 7.12, any Holder who has been a bona fide Holder of a
Contingent Convertible Capital Security of such series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the
Contingent Convertible Capital Securities of such series. 
 (f) The Company shall give notice to Holders of each resignation and each
removal of the Trustee with respect to the Contingent Convertible Capital Securities of any series and each appointment of a successor Trustee with respect to the Contingent Convertible Capital Securities of any series to the Holders in the manner
and to the extent provided in Section 1.06. Each notice shall include the name of the successor Trustee with respect to the Contingent Convertible Capital Securities of such series and the address of its Corporate Trust Office. 

Section 7.12. Acceptance of Appointment by Successor. 

(a) In case of the appointment hereunder of a successor Trustee with respect to all Contingent Convertible Capital Securities, every such
successor Trustee so appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and
such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on request of the Company or the successor Trustee, such retiring Trustee shall,
upon payment of its charges and subject to its lien provided for in Section 7.08, execute and deliver an instrument transferring to such successor Trustee, all the rights, powers and trusts of the retiring Trustee and shall duly assign,
transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder. 

  
 90 

 (b) In case of the appointment hereunder of a successor Trustee with respect to the
Contingent Convertible Capital Securities of one or more (but not all) series, the Company, the retiring Trustee and each successor Trustee with respect to the Contingent Convertible Capital Securities of such series shall execute and deliver an
indenture supplemental hereto wherein each successor Trustee shall accept such appointment and which (1) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the
rights, powers, trusts and duties of the retiring Trustee with respect to the Contingent Convertible Capital Securities of such series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with
respect to all Contingent Convertible Capital Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Contingent
Convertible Capital Securities of such series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and (3) shall add to or change any of the provisions of this Contingent Convertible Capital
Securities Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee; and upon the
execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act, deed or conveyance, shall become
vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Contingent Convertible Capital Securities of such series to which the appointment of such successor Trustee relates; but, on request of the Company or
any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Contingent Convertible Capital Securities of such
series to which the appointment of such successor Trustee relates, subject to the lien provided for in Section 7.08. 
 (c) Upon
request of any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in paragraph (a) or (b) of
this Section, as the case may be. 

  
 91 

 (d) No successor Trustee shall accept its appointment unless at the time of such acceptance
such successor Trustee shall be qualified and eligible under this Article 7. 
 Section 7.13. Merger, Conversion, Consolidation or
Succession to Business. Any Person into which the Trustee may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any Person
succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such Person shall be otherwise qualified and eligible under this Article, without the execution or filing
of any paper or any further act on the part of any of the parties hereto. In case any Contingent Convertible Capital Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or
consolidation to such authenticating Trustee may adopt such authentication and deliver the Contingent Convertible Capital Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Contingent
Convertible Capital Securities. 
 Section 7.14. Preferential Collection of Claims. If and when the Trustee shall be or become a
creditor of the Company (or any other obligor upon the Contingent Convertible Capital Securities of a series), the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of claims against the Company (or any
such other obligor). 
 Section 7.15. Appointment of Authenticating Agent. The Trustee may at any time appoint an Authenticating
Agent or Agents with respect to one or more series of Contingent Convertible Capital Securities which shall be authorized to act on behalf of the Trustee to authenticate Contingent Convertible Capital Securities of such series upon original issue,
or issued upon exchange, registration of transfer or partial redemption thereof or in lieu of destroyed, lost or stolen Contingent Convertible Capital Securities, and Contingent Convertible Capital Securities so authenticated shall be entitled to
the benefits of this Contingent Convertible Capital Securities Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Contingent Convertible Capital Securities
Indenture to the authentication and delivery of Contingent Convertible Capital Securities by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the
Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a corporation or national
banking association organized and doing business under the laws of the United States, any State thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than
$50,000,000 and subject to supervision or examination by Federal or State or District of Columbia authority. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at
any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section.

 Any Person into which an Authenticating Agent may be merged or converted or with which it
may be consolidated, or any Person resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any Person succeeding to the corporate agency or corporate trust business of an Authenticating Agent,
shall continue to be an Authenticating Agent, provided such Person shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent. 

An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Company. The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating
Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall give notice to the Holders of Contingent Convertible
Capital Securities in the manner and to the extent provided in Section 1.06. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section. 

The Company agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this
Section 7.15. 
 If an appointment with respect to one or more series is made pursuant to this Section, the Contingent Convertible
Capital Securities of such series may have endorsed thereon, in lieu of the Trustee’s certificate of authentication, an alternate certificate of authentication in substantively the following form:

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 the Contingent Convertible Capital Securities and this Contingent Convertible Capital Securities 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. In all cases, the Paying Agent shall have no obligation to gross up any payment made subject to any deduction or withholding pursuant to Applicable Law.
In addition, amounts deducted or withheld by the Paying Agent as described in this paragraph will be treated as paid to the Holder of the Contingent Convertible Capital Securities, and the Company will not pay Additional Amounts in respect of such
deduction or withholding, except to the extent required under Section 11.04.

The Company may, without the consent of Holders of any Contingent Convertible Capital Securities of any series Outstanding under this
Contingent Convertible Capital Securities Indenture, consolidate or amalgamate with or merge into any other corporation or convey or transfer or lease its properties and assets substantially as an entirety to any Person, provided that: 

(a) any successor corporation formed by any consolidation, amalgamation or merger, or any transferee or lessee of the Company’s assets,
(i) shall be a company organized and existing under the laws of any part of the European Union, and (ii) shall expressly assume, by an indenture supplemental hereto, executed and delivered to the Trustee, in the case of the Company, in

which, after notice or lapse of time or both, would become an Enforcement Event, shall have occurred and be continuing; and 
 (c) the
Company shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such consolidation, amalgamation, merger, conveyance or transfer and such supplemental indenture comply with this Article and that

 Section 9.02. Successor Corporation Substituted. In the event of any merger,
consolidation, sale, conveyance permitted by Section 9.01 above, Additional Amounts under the Contingent Convertible Capital Securities will thereafter be payable in respect of taxes imposed by the acquiring corporation’s, or the resulting
corporation’s, jurisdiction of incorporation or tax residence (subject to exceptions equivalent to those that apply to the obligation to pay Additional Amounts pursuant to Section 11.04 in respect of taxes imposed by the laws of the
Kingdom of Spain) rather than taxes imposed by the Kingdom of Spain. Additional Amounts with respect to payments of Distributions due prior to the date of such merger, consolidation, sale, conveyance or lease will be payable only in respect of taxes
imposed by the Kingdom of Spain. The acquiring or resulting corporation, as the case may be, will also be entitled to redeem the Contingent Convertible Capital Securities in the circumstances described in Section 12.08 with respect to any
change or amendment to, or change in the application or official interpretation of the laws or regulations of such jurisdiction, which change or amendment must occur subsequent to the date of any merger, consolidation, sale or conveyance or lease
permitted by Section 9.01 if the successor entity is not incorporated or tax resident in the Kingdom of Spain. In the event of assumption of the Company’s obligations in connection with a merger, consolidation, sale or conveyance of
substantially all of its assets, the Company shall be released from all obligations and covenants under this Contingent Convertible Capital Securities Indenture or the Contingent Convertible Capital Securities, as the case may be, and the successor
corporation formed by such consolidation or amalgamation or into which the Company is merged or to which such conveyance or transfer is made shall succeed to and be substituted for, and may exercise every right and power of, the Company under this
Contingent Convertible Capital Securities Indenture with the same effect as if such successor corporation had been named as the Company. 

Section 9.03. Assumption of Obligations. Subject to the prior consent of the European Central Bank, if required, any direct or
indirect subsidiary of the Company may assume the obligations of the Company under the Contingent Convertible Capital Securities without the consent of the Holders of the Contingent Convertible Capital Securities of such series, provided that: 

(a) the successor entity shall expressly assume such obligations by an amendment to this Contingent Convertible Capital Securities Indenture,
executed by the Company and such successor entity, if applicable, and delivered to the Trustee, in form satisfactory to the Trustee, and the Company shall, by amendment of this Contingent Convertible Capital Securities Indenture, unconditionally
guarantee all obligations of such successor entity under the Contingent Convertible Capital Securities Indenture of such series and this Contingent Convertible Capital Securities Indenture so modified by such amendment; 

(b) immediately after giving effect to such assumption of obligations, no Enforcement Event and no event which, after notice or lapse of time
or both, would become an Enforcement Event, shall have occurred and be continuing; and 
 (c) the Company shall have delivered to the
Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such assumption complies with this Article and that all conditions precedent herein provided for relating to such assumption have been complied with. 

  
 98 

 Upon any such assumption, the successor entity shall succeed to, and be substituted for, and
may exercise every right and power of, the Company under this Contingent Convertible Capital Securities Indenture with respect to any such Contingent Convertible Capital Securities with the same effect as if such successor entity had been named as
the Company in this Contingent Convertible Capital Securities Indenture, and the Company or any legal and valid successor corporation which shall theretofore have become such in the manner prescribed herein, shall be released from all liability as
obligor upon any such Contingent Convertible Capital Securities except as described in the following paragraph. 
 In the event of any
assumption, Additional Amounts under the Contingent Convertible Capital Securities of such series will be payable in respect of taxes imposed by the assuming corporation’s jurisdiction of incorporation or tax residence (subject to exceptions
equivalent to those that apply to the obligation to pay Additional Amounts pursuant to Section 11.04 in respect of taxes imposed by the laws of the Kingdom of Spain) on payments of Distributions or Liquidation Preference made on or subsequent
to the date of such assumption. Additional Amounts with respect to payments of Distributions due prior to the date of such assumption will be payable only in respect of taxes imposed by the Kingdom of Spain. The assuming corporation will also be
entitled to redeem the Contingent Convertible Capital Securities of such series in the circumstances described in Section 12.08 with respect to any change or amendment to, or change in the application or official interpretation of the laws or
regulations of such jurisdiction, which change or amendment must occur subsequent to the date of any such assumption if the assuming entity is not incorporated or tax resident in the Kingdom of Spain. In the event of any such assumption, all
obligations of the Company under the Contingent Convertible Capital Securities of such series shall immediately be discharged. 

Section 9.04. Substitution and Variation. If a Capital Event or a Tax Event occurs and is continuing, the Company may substitute
all (but not some) of the Contingent Convertible Capital Securities of any series or modify the terms of all (but not some) of the Contingent Convertible Capital Securities of such series, without any requirement for the consent or approval of the
Holders of the Contingent Convertible Capital Securities of such series, so that they are substituted for, or varied to, become, or remain, Qualifying Notes, subject to having given not less than 15 nor more than 30 days’ notice to the Holders
of the Contingent Convertible Capital Securities (with a concurrent copy to the Trustee) of such series in accordance with Section 1.06 (which notice shall be irrevocable and shall specify the date for substitution or, as applicable,
variation). 
 Any such notice shall specify the relevant details of the manner in which such substitution or variation shall take effect
and where the Holders of the Contingent Convertible Capital Securities of such series can inspect or obtain copies of the new terms and conditions of the Contingent Convertible Capital Securities. Such substitution or variation will be effected
without any cost or charge to such Holders. 
 The Contingent Convertible Capital of any series shall cease to bear interest from (an
including) the date of substitution thereof. 

  
 99 

 Any holder or beneficial owner of the Contingent Convertible Capital Securities of any
series shall, by virtue of its acquisition of the Contingent Convertible Capital Securities of any series or any beneficial interest therein, be deemed to accept the substitution or variation of the terms of the Contingent Convertible Capital
Securities of such series and to grant to the Company full power and authority to take any action and/or to execute and deliver any document in the name and/or on behalf of such Holder which is necessary or convenient to complete the substitution or
variation of the terms of the Contingent Convertible Capital Securities of such series.

each Paying Agent for any series of Contingent Convertible Capital Securities other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this
Section, that such Paying Agent will: 
 (a) hold all sums held by it for the payment of the Liquidation Preference or Distributions on
Contingent Convertible Capital Securities of that series in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided; 

(b) give the Trustee notice of any default by the Company (or any other obligor upon the Contingent Convertible Capital Securities of that
series) in the making of any payment, when due and payable, or Liquidation Preference or Distributions on Contingent Convertible Capital Securities of that series; and 

(c) at any time during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so
held in trust by such Paying Agent. 
 The Company may at the time, for the purpose of obtaining the satisfaction and discharge of this
Contingent Convertible Capital Securities Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee such Paying Agent shall be released from all further liability with respect to such money.

  
 105 

 Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the Liquidation Preference or Distributions on any Contingent Convertible Capital Security of any series and remaining unclaimed for two years after such Liquidation Preference or Distributions have become due and payable
shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Contingent Convertible Capital Security shall thereafter, as an unsecured general creditor, look only to
the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying
Agent, before being required to make any such repayment, may at the expense of the Company cause to be published at least once, in an Authorized Newspaper, notice that such money remains unclaimed and that, after a date specified therein, which
shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will be paid to the Company. 

Section 11.04. Additional Amounts. 

(a) Unless otherwise specified pursuant to Section 3.01, all payments of Distributions and other amounts payable (excluding, for the
avoidance of doubt, repayment of principal) in respect of Contingent Convertible Capital Securities by the Company will be made free and clear of and without withholding or deduction for or on account of any present or future taxes, duties,
assessments or governmental charges (collectively “Taxes”) of whatever nature imposed or levied by or on behalf of Spain or any political subdivision thereof or any authority or agency therein or thereof having power to tax, unless the
withholding or deduction of such taxes, duties, assessments or governmental charges is required by law. In that event, the Company shall pay, in respect of any withholding or deduction imposed on payments of Distributions only (and not Liquidation
Preference), such additional amounts (“Additional Amounts”) as will result in Holders of any series of Outstanding Contingent Convertible Capital Securities receiving such amounts as they would have received had no such withholding
or deduction been required, provided that no payments of Additional Amounts will be made if and to the extent that the Company has insufficient Available Distributable Items to pay such additional amounts, Distributions on the Contingent Convertible
Capital Securities of any series scheduled for payment in the then current financial year and any equivalent payments scheduled to be made in the then current financial year in respect of any other Parity Securities and CET1 Capital securities then
outstanding, in each case excluding any portion of such payments already accounted for in determining the Available Distributable Items. 

(b) The Company shall not be required to pay any Additional Amounts in relation to any payment in respect of any Contingent Convertible
Capital Security: 
 (i) to, or to a third party on behalf of, a Holder if the Holder or the beneficial owner of Contingent
Convertible Capital Securities of any series is liable for such Taxes in respect of such Contingent Convertible Capital Security by reason of his having some connection with Spain other than (i) the mere holding of such Contingent Convertible
Capital Security or (ii) the receipt of any payment in respect of such Contingent Convertible Capital Security; or 

(ii) to, or to a third party on behalf of, a Holder in respect of whose Contingent Convertible Capital Securities the Company
does not receive such information as may be required in order to comply with the applicable Spanish tax reporting obligations (as amended or restated from time to time), including but not limited to the receipt in a timely manner of a duly executed
and completed certificate in accordance with Law 10/2014 and Royal Decree 1065/2007, as amended, and any implementing legislation or regulation; or 

  
 106 

 (iii) to, or to a third party on behalf of, a Holder of Contingent
Convertible Capital Securities in respect of whom the Company does not receive such information concerning such Holder’s identity and tax residence as may be required in order to comply with the procedures that may be implemented to comply with
the interpretation of Royal Decree 1065/2007 eventually made by the Spanish tax authorities; or 
 (iv) presented for payment
(where presentation is required) more than 30 days after the Relevant Date, except to the extent that the relevant Holder would have been entitled to such Additional Amounts on presenting the same for payment on the expiry of such period of 30 days;
or 
 (v) in relation to any estate, inheritance, gift, sales, transfer or similar taxes; or 

(vi) to, or to a third party on behalf of, individuals resident for tax purposes in the Kingdom of Spain if the Spanish tax
authorities determine that payments made to such individuals are not exempt from withholding tax and require a withholding to be made; or 

(vii) to, or to a third party on behalf of, a Spanish-resident legal entity subject to Spanish corporation tax if the Spanish
tax authorities determine that the Contingent Convertible Capital Securities of any series do not comply with exemption requirements specified in the Reply to a Consultation of the Directorate General for Taxation (Dirección
General de Tributos) dated 27 July 2004 and require a withholding to be made; or 
 (viii) where the withholding or
deduction is required pursuant to an agreement described in Section 1471(b) of the Code or otherwise imposed pursuant to Sections 1471 through 1474 of the Code (“FATCA”), any regulations or agreements thereunder, any official
interpretations thereof, any intergovernmental agreements with respect thereto (including the intergovernmental agreement between the United States and Spain on the implementation of FATCA), or any law implementing an intergovernmental agreement or
any regulations or official interpretations relating thereto. 
 (c) In addition, Additional Amounts will not be payable with respect to any
Taxes that are imposed in respect of any combination of the items listed in (b)(i) through (b)(viii) set forth above. 

  
 107 

 (d) Additional Amounts will also not be paid with respect to any payment to a Holder who is
a fiduciary, a partnership, a limited liability company or person other than the sole beneficial owner of that payment, to the extent that payment would be required by the laws of Spain (or any political subdivision thereof) to be included in the
income, for tax purposes, of a beneficiary or settlor with respect to the fiduciary, a member of that partnership, an interest holder in that limited liability company or a beneficial owner who would not have been entitled to the Additional Amounts
had it been the Holder. 
 For the purposes of this Section 11.04: 

“Relevant Date” means, in respect of any payment, the date on which such payment first becomes due and payable, except that, if the
full amount of the moneys payable has not been duly received by the Principal Paying Agent on or prior to such due date, it means the date on which, the full amount of such moneys having been so received and being available for payment to Holders,
notice to that effect is duly given to the Holders in accordance with Section 1.06. 
 In the event that any withholding or deduction
for or on account of any taxes by the Company is required, at least 10 days prior to each date of payment of Liquidation Preference of or Distributions on the relevant series of Contingent Convertible Capital Securities, or, if later, promptly after
the obligation to withhold or deduct becomes known to the Company, the Company will furnish to the Trustee and the Paying Agent, if other than the Trustee, an Officer’s Certificate specifying the amount required to be withheld or deducted on
such payments to such Holders, certifying that the Company shall pay such amounts required to be withheld to the appropriate taxing jurisdiction and certifying to the fact that the Additional Amounts will be payable and the amounts so payable to
each Holder, and that the Company will pay to the Trustee or the Paying Agent the Additional Amounts required to be paid; provided that no such Officer’s Certificate will be required prior to any date of payment of Liquidation Preference of or
Distributions on such Contingent Convertible Capital Securities if there has been no change with respect to the matters set forth in a prior Officer’s Certificate. The Trustee and Paying Agent may rely on the fact that any Officer’s
Certificate contemplated by this paragraph has not been furnished as evidence of the fact that no withholding or deduction for or on account of any taxes is required. The Company covenants to indemnify the Trustee and Paying Agent for and to hold
them harmless against any loss, liability or expense reasonably incurred without negligence or bad faith on their part arising out of or in connection with actions taken or omitted by any of them in reliance on any such Officer’s Certificate
furnished pursuant to this paragraph or on the fact that any Officer’s Certificate contemplated by this paragraph has not been furnished. 

Except where the context requires otherwise, any references in this Contingent Convertible Capital Securities Indenture to Distributions in
respect of the Contingent Convertible Capital Securities shall include any Additional Amounts payable with respect thereto. 

Section 11.05. Corporate Existence. Subject to Article 9, the Company will do or cause to be done all things necessary to preserve
and keep in full force and effect its corporate existence, provided, however, that the foregoing shall not obligate the Company to preserve any such right or franchise if the Company shall determine that the preservation thereof is no longer
desirable in the conduct of its business and that the loss thereof is not disadvantageous in any material respect to any Holder. 

  
 108 

 Section 11.06. Statement as to Compliance. The Company will deliver to the
Trustee, within 120 days after the end of each fiscal year, a certificate in compliance with Section 314(a)(4) of the Trust Indenture Act.

CAPITAL SECURITIES 
 Section 12.01. Applicability of Article. Contingent Convertible Capital
Securities of any series shall be redeemable in accordance with their terms and (except as otherwise specified pursuant to Section 3.01 for Contingent Convertible Capital Securities of any series) in accordance with this Article. Contingent

Convertible Capital Securities of such series to be redeemed. In the case of any redemption of Contingent Convertible Capital Securities of any series prior to the expiration of any provision restricting such redemption provided in the terms of such
Contingent Convertible Capital Securities or elsewhere in this Contingent Convertible Capital Securities Indenture, the Company shall furnish the Trustee with respect to such Contingent Convertible Capital Securities with an Officer’s
Certificate evidencing compliance with or waiver of such provision. 
 Section 12.03. Selection by Trustee of Contingent Convertible
Capital Securities to be Redeemed. If less than all the Contingent Convertible Capital Securities of any series are to be redeemed, the particular Contingent Convertible Capital Securities to be redeemed shall be selected not less than 15 days
nor more than 30 days prior to the Redemption Date by the Trustee, from the Outstanding Contingent Convertible Capital Securities of such series not previously called for redemption, pro rata, by lot or by such method as the Trustee shall deem fair
and appropriate and which may provide for the selection for redemption of portions (equal to the minimum authorized denomination for Contingent Convertible Capital Securities of that series or any multiple thereof) of the Liquidation Preference of
Contingent Convertible Capital Securities of such series of a denomination larger than the minimum authorized denomination for Contingent Convertible Capital Securities of that series. Redemption in accordance with regulations of the list authority,
stock exchange and/or quotation system shall conform to the prospectus. 

  
 109 

 The Trustee shall promptly notify the Company in writing of the Contingent Convertible
Capital Securities selected for redemption and, in the case of any Contingent Convertible Capital Securities selected for partial redemption, the Liquidation Preference thereof to be redeemed. 

For all purposes of this Contingent Convertible Capital Securities Indenture, unless the context otherwise requires, all provisions relating
to the redemption of Contingent Convertible Capital Securities shall relate in the case of any Contingent Convertible Capital Securities redeemed or to be redeemed only in part, to the portion of the Liquidation Preference of such Contingent
Convertible Capital Security which has been or is to be redeemed. 
 Section 12.04. Redemption Procedures; Notice of Redemption.

 (a) The decision to redeem the Contingent Convertible Capital Securities must be irrevocably notified by the Company to Holders of the

(información privilegiada/otra información relevante) announcement with the CNMV and its publication in accordance with the rules and regulations of any applicable stock exchange or other relevant authority and
(ii) in accordance with Section 1.06, and to the Trustee (with a copy of the Regulator’s consent to the redemption if and as required by the Applicable Banking Regulations) at least five (5) Business Days prior to such date,
unless a shorter notice period shall be satisfactory to the Trustee. 
 (b) Any notice of redemption will state: the redemption date; that
on the redemption date the Redemption Price will, subject to the satisfaction of the conditions set forth in this Contingent Convertible Capital Securities Indenture become due and payable upon each Contingent Convertible Capital Security being
redeemed and that, subject to certain exceptions, Distributions will cease to accrue on or after that date; the place or places where the Contingent Convertible Capital Securities are to be surrendered for payment of the redemption price; and the
CUSIP, Common Code and/or ISIN number or numbers, if any, with respect to the Contingent Convertible Capital Securities being redeemed. 

(c) If the Company gives notice of redemption of the Contingent Convertible Capital Securities of any series, then by 11 a.m. (CET) on the
relevant redemption date, the Company will: 
 (i) irrevocably deposit with the Principal Paying Agent funds sufficient to
pay the Redemption Price; and 
 (ii) give the Principal Paying Agent irrevocable instructions and authority to pay the
Redemption Price to the Holders. 

  
 110 

 (d) If the notice of redemption has been given on any series of Contingent Convertible
Capital Securities, and the funds deposited and instructions and authority to pay given as required above, then on the date of such deposit: 

(i) Distributions on the Contingent Convertible Capital Securities of such series shall cease to accrue; 

(ii) such Contingent Convertible Capital Securities of such series will no longer be considered Outstanding; and 

(iii) the Holders of Contingent Convertible Capital Securities of such series will no longer have any rights as holders except
the right to receive the Redemption Price.

notice of redemption has been given and the funds are not deposited as required on the date of such deposit or if the Company improperly withholds or refuses to pay the Redemption Price of the Contingent Convertible Capital Securities of such
series, Distributions will continue to accrue, subject as provided in Section 3.08 and Section 3.09, at the rate specified from (and including) the redemption date to (but excluding) the date of actual payment of the Redemption Price. 

(f) The Company may not give a notice of redemption pursuant to this Section 12.04 if a Trigger Event Notice has been given. If a Trigger
Event Notice is given after a notice of redemption shall have been given by the Company but before the redemption has occurred, such notice of redemption shall automatically be revoked and be null and void and the relevant redemption shall not be
made. 
 Section 12.05. Deposit of Redemption Price. On or prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as Paying Agent, segregate and hold in trust as provided in Section 11.03) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be a
Distribution Date) accrued but unpaid Distributions on, all the Contingent Convertible Capital Securities which are to be redeemed on that date. 

Section 12.06. Contingent Convertible Capital Securities Payable on Redemption Date. Notice of redemption having been given as set
forth in Section 12.04, the Contingent Convertible Capital Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Company shall
default in the payment of the Redemption Price and Distributions, if any) such Contingent Convertible Capital Securities shall cease to accrue Distributions for the period following the Redemption Date. Upon surrender of any such Contingent
Convertible Capital Security for redemption in accordance with Section 12.04, such Contingent Convertible Capital Security shall be paid by the Company at the Redemption Price, together with any accrued but unpaid Distributions thereon to (but
excluding) the Redemption Date; provided, however, that unless otherwise specified as contemplated by Section 3.01, a Distribution which is payable on a Distribution Date which is the Redemption Date, shall be payable to the Holders of
such Contingent Convertible Capital Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Regular Record Dates according to the terms of the Contingent Convertible Capital Securities and the
provisions of Section 3.07. Contingent Convertible Capital Securities in definitive form shall be presented for redemption to the Paying Agent. 

  
 111 

 If any Contingent Convertible Capital Security called for redemption shall not be so paid
upon surrender thereof for redemption, the Contingent Convertible Capital Security shall, until paid, continue to accrue Distributions from and after the Redemption Date in accordance with its terms and the provisions of Section 3.07. 

Section 12.07. Contingent Convertible Capital Securities Redeemed In Part. Any Contingent Convertible Capital Security which is to
be redeemed only in part shall be surrendered at a Place of Payment therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed
by, the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such Contingent Convertible Capital Security without service charge, a new Contingent
Convertible Capital Security or Contingent Convertible Capital Securities of the same series of any authorized denomination as requested by such Holder, in Liquidation Preference equal to and in exchange for the unredeemed portion of the Liquidation
Preference of the Contingent Convertible Capital Security so surrendered. 
 Section 12.08. Optional Redemption Due To Changes In
Tax Treatment. Unless otherwise provided as contemplated by Section 3.01 with respect to the Contingent Convertible Capital Securities of any series, if, on or after the date of issuance of any series of Contingent Convertible Capital
Securities, (i) there is a Tax Event, and (ii) such circumstances are evidenced by the delivery by the Company to the Trustee of a copy of the Regulator’s consent to the redemption, if and as required by the Applicable Banking
Regulations, the Contingent Convertible Capital Securities of such series may be redeemed, in whole but not in part, at the option of the Company, and may only take place in accordance with Applicable Banking Regulations then in force, at any time,
at the Redemption Price. 
 Section 12.09. Optional Redemption Due To Capital Event. Unless otherwise provided as contemplated
by Section 3.01 with respect to the Contingent Convertible Capital Securities of any series, if, on or after the issue date of the Contingent Convertible Capital Securities of any series, (i) there is a Capital Event, and (ii) such

 112 

 (b) Notwithstanding any other provision of Section 4.06 and subject to compliance with
the provisions of the Spanish Companies Act and/or with any Applicable Banking Regulations, the Company or any member of the Group may exercise such rights as it may from time to time enjoy to purchase or redeem or buy back any shares of the Company

ARTICLE 13 

SUBORDINATION OF CONTINGENT CONVERTIBLE CAPITAL
SECURITIES 
 Section 13.01. Contingent Convertible Capital Securities Subordinate to Senior Claims.
(a) Unless previously converted into Common Shares pursuant Section 4.01, the payment obligations of the Company under the Contingent Convertible Capital Securities of any series constitute direct, unconditional, unsecured and subordinated
obligations (créditos subordinados) of the Company according to Article 281.1.2o of the Spanish Insolvency Law and, in accordance with Additional Provision 14.3o of Law 11/2015, but subject to any other ranking
that may apply as a result of any mandatory provision of law (or otherwise), upon the insolvency of the Company, for so long as the obligations of the Company in respect of the Contingent Convertible Capital Securities of any series constitute
Additional Tier 1 Instruments, rank: 
  

	 	(i)	 pari passu among themselves and with (a) all other claims in respect of any outstanding Additional
Tier 1 Instruments and (b) any other subordinated obligations (créditos subordinados) which by law and/or by their terms, to the extent permitted by Spanish law, rank pari passu with the Company’s obligations under
Additional Tier 1 Instruments; 

  

	 	(ii)	 junior to (a) any unsubordinated obligations (créditos ordinarios) of the Company,
(b) any obligations of the Company in respect of Tier 2 Instruments and (c) any other subordinated obligations (créditos subordinados) which by law and/or by their terms, to the extent permitted by Spanish law, rank senior to
the Company’s obligations under Additional Tier 1 Instruments; and 

  
 113 

	 	(iii)	 senior to (a) any claims for the liquidation amount of the Common Shares and (b) any other
subordinated obligations (créditos subordinados) of the Company which by law and/or by their terms, to the extent permitted by Spanish law, rank junior to the Company’s obligations under Additional Tier 1 Instruments.

 (b) The Company agrees with respect to any series of Contingent Convertible Capital Securities and each holder of
Contingent Convertible Capital Securities of any series, by his or her acquisition of a Contingent Convertible Capital Security, will be deemed to have agreed to the subordination as described in this Section 13.01. Each such holder will be
deemed to have irrevocably waived his or her rights of priority which would otherwise be accorded to him or her under the laws of Spain, to the extent necessary to effectuate the subordination provisions of the Contingent Convertible Capital
Security. In addition, each holder of Contingent Convertible Capital Securities of any series by his or her acquisition of the securities authorizes and directs the applicable trustee on his or her behalf to take such action as may be necessary or
appropriate to effectuate the subordination of the relevant Contingent Convertible Capital Securities as provided in this Contingent Convertible Capital Securities Indenture and as summarized herein and appoints the Trustee his or her attorney-in-fact for any and all such purposes. 
 (c) The Company
may not issue, or guarantee the issue of, any Parity Securities or other instruments equivalent to Parity Securities ranking, either directly or through a guarantee, senior to the Contingent Convertible Capital Securities of any series, unless the
terms and conditions of the Contingent Convertible Capital Securities of such series are amended so as to rank pari passu with any such issue of senior securities. 

Section 13.02. Waiver of Right of Set-Off. Subject to applicable law, neither any holder
or beneficial owner of the Contingent Convertible Capital Securities of any series nor the Trustee acting on behalf of the holders of the Contingent Convertible Capital Securities of such series may exercise, claim or plead any right of set-off, compensation or retention in respect of any amount owed to it by the Company in respect of, or arising under, or in connection with, the Contingent Convertible Capital Securities of such series or this
Contingent Convertible Capital Securities Indenture and each Holder and beneficial owner of the Contingent Convertible Capital Securities of such series, by virtue of its holding of any Contingent Convertible Capital Securities of such series or any
interest therein, and the Trustee acting on behalf of the holders of the Contingent Convertible Capital Securities of such series, shall be deemed to have waived all such rights of set-off, compensation or
retention. If, notwithstanding the above, any amounts due and payable to any holder or beneficial owner of a Contingent Convertible Capital Security of any series or any Distributions thereon by the Company in respect of, or arising under, the
Contingent Convertible Capital Securities of such series are discharged by set-off, such holder or beneficial owner shall, subject to applicable law, immediately pay an amount equal to the amount of such
discharge to the Company (or, if a Liquidation Event shall have occurred, the liquidator or administrator of the Company, as the case may be) and, until such time as payment is made, shall hold an amount equal to such amount in trust (where
possible) or otherwise for the Company (or the liquidator or administrator of the Company, as the case may be) and, accordingly, any such discharge shall be deemed not to have taken place. 

  
 114 

 Section 13.03. Provisions Solely to Define Relative Rights. The provisions of
this Article 13 are and are intended solely for the purpose of defining the relative rights of the Holders of the Contingent Convertible Capital Securities of each series on the one hand and the Senior Creditors on the other hand. Nothing contained
in this Article or elsewhere in this Contingent Convertible Capital Securities Indenture or in such Contingent Convertible Capital Securities is intended to or shall (a) impair, as among the Company and the Holders of the Contingent Convertible
Capital Securities, the obligation of the Company, which is absolute and unconditional, to pay to the holders of such claims the Liquidation Preference and Distributions on such Contingent Convertible Capital Securities as and when the same shall
become due and payable in accordance with their terms and this Contingent Convertible Capital Securities Indenture; or (b) affect the relative rights against the Company of the Holders of such Contingent Convertible Capital Securities; or
(c) prevent the Trustee or the Holder of any Contingent Convertible Capital Securities of the series from exercising all remedies otherwise permitted by applicable law upon default under this Contingent Convertible Capital Securities Indenture,
subject to the rights, if any, under this Article of the Senior Creditors to receive cash, property or securities otherwise payable or deliverable to the Trustee or such holder. 

Section 13.04. Trustee to Effectuate Subordination. Each Holder of a Contingent Convertible Capital Security by his acceptance
thereof authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to effectuate the subordination of the Contingent Convertible Capital Securities provided in this Article 13 and appoints the Trustee his
attorney-in-fact for any and all such purposes. 

Section 13.05. Trustee Not Fiduciary for Senior Creditors. With respect to the Senior Creditors, the Trustee undertakes to perform
or to observe only such of its covenants and obligations as are specifically set forth in this Contingent Convertible Capital Securities Indenture, and no implied covenants or obligations with respect to the Senior Creditors shall be read into this
Contingent Convertible Capital Securities Indenture against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the Senior Creditors and shall not be liable to any such holders if it shall mistakenly pay over or distribute to
Holders of Contingent Convertible Capital Securities of the series or to the Company or to any other Person cash, property or securities to which any Senior Creditors shall be entitled by virtue of this Article or otherwise. 

Section 13.06. Rights of Trustee as Senior Creditor; Preservation of Trustee’s Rights. The Trustee in its
individual or any other capacity shall be entitled to all the rights set forth in this Article with respect to any claims of Senior Creditors which may at any time be held by it, to the same extent as any other Senior Creditor, and nothing in this
Contingent Convertible Capital Securities Indenture or the Trust Indenture Act shall deprive the Trustee of any of its rights as such holder. 

Nothing in this Article shall apply to claims of, or payments to, the Trustee under or pursuant to Section 6.08 and Section 7.08.

  
 115 

 Section 13.07. Article Applicable to Paying Agents. At all times when a Paying
Agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the term “Trustee” as used in this Article shall in such case (unless the context otherwise requires) be construed as extending to
and including such Paying Agent within its meaning as fully for all intents and purposes as if such Paying Agent were named in this Article in addition to or in place of the Trustee; provided, however, that Section 13.06 shall not apply
to the Company or any Affiliate of the Company if it or such Affiliate acts as Paying Agent. 
 ARTICLE 14 

BAIL-IN AND RESOLUTION
ACTIONS 
 Section 14.01. Agreement and Acknowledgment with Respect to the Exercise of the Bail-in Power. 
 (a) Notwithstanding any other term of the Contingent Convertible Capital Securities
of any series or any other agreements, arrangements, or understandings between the Company and any Holder of the Contingent Convertible Capital Securities of any series, by its acquisition of the Contingent Convertible Capital Securities of any
series, each Holder (which, for the purposes of this Section 14.01, includes each holder of a beneficial interest in the Contingent Convertible Capital Securities of any series) acknowledges, accepts, consents to and agrees: 

(i) to be bound by effect of the exercise of the Bail-in Power by the Relevant
Resolution Authority, which may include and result in any of the following, or some combination thereof: 
  

	 	•	 	 the reduction of all, or a portion, of the Amounts Due on a permanent basis; 

 

	 	•	 	 the conversion of all, or a portion, of the Amounts Due into shares, other securities or other obligations of the
Company or another person (and the issue to the Holder of such shares, securities or obligations), including by means of an amendment, modification or variation of the terms of the Contingent Convertible Capital Securities, in which case the Holder
agrees to accept in lieu of its rights under such Contingent Convertible Capital Securities any such shares, other securities or other obligations of the Company or another person; 

 

	 	•	 	 the cancellation of the Contingent Convertible Capital Securities or Amounts Due; 

 

	 	•	 	 the amendment or alteration of the maturity of the Contingent Convertible Capital Securities or amendment of the
interest payable on the Contingent Convertible Capital Securities, or the date on which the interest becomes payable, including by suspending payment for a temporary period; and 

  
 116 

 (ii) that the terms of the Contingent Convertible Capital Securities are
subject to, and may be varied, if necessary, to give effect to, the exercise of the Bail-in Power by the Relevant Resolution Authority. 

(b) No repayment or payment of Amounts Due on the Contingent Convertible Capital Securities of any series will become due and payable or be
paid after the exercise of any Bail-in Power by the Relevant Resolution Authority if and to the extent such amounts have been reduced, converted, cancelled, amended or altered as a result of such exercise.

 The potential write-down or cancellation of all or a portion of the principal amount of—or Distributions on—the Contingent
Convertible Capital Securities or the conversion of the Contingent Convertible Capital Securities into shares, other security or other obligations in connection with the exercise of any Bail-in Power by the
Relevant Resolution Authority is separate and distinct from a conversion or write-down following a Trigger Event although these events may occur consecutively. 

(c) The exercise of the Bail-in Power by the Relevant Resolution Authority with respect to the
Contingent Convertible Capital Securities shall not constitute an Event of Default or an Enforcement Event and the terms and conditions of the Contingent Convertible Capital Securities shall continue to apply in relation to the residual principal
amount of, or outstanding amount payable with respect to, the Contingent Convertible Capital Securities subject to any modification of the amount of Distributions payable to reflect the reduction of the principal amount, and any further modification
of the terms that the Relevant Resolution Authority may decide in accordance with applicable laws and regulations relating to the resolution of credit institutions, investment firms and/or Group entities incorporated in the relevant member state.

 (d) Neither a reduction or cancellation, in part or in full of the Amounts Due on, the conversion thereof into another security or
obligation of the Company or another person, as a result of the exercise of the Bail-in Power by the Relevant Resolution Authority with respect to the Company, nor the exercise of the Bail-in Power by the Relevant Resolution Authority with respect to the Contingent Convertible Capital Securities of any series will be an Enforcement Event. 

(e) By its acquisition of the Contingent Convertible Capital Securities of any series, each Holder of the Contingent Convertible Capital
Securities of such series, (which, for the purposes of this Section 14.01, includes each holder of a beneficial interest in the Contingent Convertible Capital Securities of such series), to the extent permitted by the Trust Indenture Act, will
waive 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 will not be liable for, any action that the Trustee takes, or abstains from
taking, in either case in accordance with the exercise of the Bail-in Power by the Relevant Resolution Authority with respect to the Contingent Convertible Capital Securities of such series. 

  
 117 

 (f) Additionally, by its acquisition of the Contingent Convertible Capital Securities of any
series, each Holder of the Contingent Convertible Capital Securities of such series acknowledges and agrees that, upon the exercise of the Bail-in Power by the Relevant Resolution Authority: 

(i) the Trustee will not be required to take any further directions from the Holders of the Contingent Convertible Capital
Securities of such series with respect to any portion of the Contingent Convertible Capital Securities of such series that are written-down, converted to equity and/or cancelled under this Contingent Convertible Capital Securities Indenture, which
authorizes Holders of a majority in aggregate outstanding Liquidation Preference of the Outstanding Contingent Convertible Capital Securities of such series to direct certain actions relating to the Contingent Convertible Capital Securities of such
series; and 
 (ii) this Contingent Convertible Capital Securities Indenture will not impose any duties upon the Trustee
whatsoever with respect to the exercise of the Bail-in Power by the Relevant Resolution Authority. 

provided, however, that notwithstanding the exercise of the Bail-in Power by the Relevant Resolution
Authority, so long as this Contingent Convertible Capital Securities of any series remain Outstanding, there will at all times be a Trustee for this Contingent Convertible Capital Securities of such series in accordance with the Contingent
Convertible Capital Securities Indenture, and the resignation and/or removal of the Trustee and the appointment of a successor Trustee will continue to be governed by this Contingent Convertible Capital Securities Indenture, including to the extent
no additional supplemental indenture or amendment is agreed upon in the event the Contingent Convertible Capital Securities of such series remain Outstanding following the completion of the exercise of the
Bail-in Power. 
 (g) By its acquisition of the Contingent Convertible Capital Securities of any
series, each Holder of the Contingent Convertible Capital Securities of such series acknowledges and agrees that neither a cancellation or deemed cancellation of the Liquidation Preference or Distributions (in each case, in whole or in part), nor
the exercise of the Bail-in Power by the Relevant Resolution Authority with respect to the Contingent Convertible Capital Securities of such series will give rise to a 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. 

(h) Each Holder of the Contingent Convertible Capital Securities of any series that acquires such Contingent Convertible Capital Securities in
the secondary market (including each beneficial owner) shall be deemed to acknowledge, agree to be bound by and consent to the same provisions specified herein to the same extent as the Holders of the Contingent Convertible Capital Securities that
acquire the Contingent Convertible Capital Securities upon their initial issuance, including, without limitation, with respect to the acknowledgment and agreement to be bound by and consent to the terms of the Contingent Convertible Capital
Securities, including in relation to the Bail-in-Power. 

  
 118 

 (i) By purchasing the Contingent Convertible Capital Securities of any series, each Holder
(including each beneficial owner) of the Contingent Convertible Capital Securities of such series shall be deemed to have authorized, directed and requested DTC and any direct participant in DTC or other intermediary through which it holds
Contingent Convertible Capital Securities of such series to take any and all necessary action, if required, to implement the exercise of the Bail-in Power with respect to the Contingent Convertible Capital
Securities of such series as it may be imposed, without any further action or direction on the part of such Holder. 
 (j) Each holder of
the Contingent Convertible Capital Securities also acknowledges and agrees that the foregoing description of the Bail-in Power and its exercise is exhaustive on the matters described herein to the exclusion of
any other agreements, arrangements or understandings relating to the application of any Bail-in Power to the Contingent Convertible Capital Securities. 

This instrument may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, but all such
counterparts shall together constitute but one and the same instrument. The exchange of copies of this Contingent Convertible Capital Securities Indenture and of signature pages by facsimile, email or electronic format (e.g., PDF, “tif” or
“jpg”) transmission and other electronically imaged signatures (including, without limitation, DocuSign and AdobeSign) shall constitute effective execution and delivery of this Contingent Convertible Capital Securities Indenture as to the
parties hereto and may be used in lieu of the original Indenture for all purposes. Signatures of the parties hereto transmitted by facsimile or electronic format (e.g., PDF, “tif” or “jpg”) shall be deemed to be their original
signatures for all purposes. This Contingent Convertible Capital Securities Indenture, any indenture supplemental hereto and any other document, certificate or opinion delivered in connection with this Contingent Convertible Capital Securities
Indenture, such supplemental indenture or the issuance and delivery of the Contingent Convertible Capital Securities may be signed by or on behalf of the Company and the Trustee by manual, facsimile, PDF or other electronically imaged signature

	 	1.	 Delivery of the Payment Information Certificate: In connection with each payment of income under the
Contingent Convertible Capital Securities, the Trustee or Paying Agent shall deliver to the Company by the close of business on the business day immediately preceding the day on which such payment is made a duly completed and executed Payment
Information Certificate substantially in the form set forth in Exhibit I hereto (Form of Payment Information Certificate). Such form may be delivered initially by email, in PDF form, by fax or by other electronic format transmission

If the Payment Information Certificate is delivered by the Trustee or Paying Agent in a timely and completed manner to the Company, the
relevant income payment will be made free and clear of Spanish withholding tax. 
 The Trustee or Paying Agent shall have no duty or
responsibility to comply with Spanish tax laws arising out of this Contingent Convertible Capital Securities Indenture, and may request and rely conclusively upon any instructions from the Company in respect of any action necessary or required to be
taken by the Trustee or Paying Agent pursuant to this Appendix 1; provided, however, that in no event shall the Trustee or Paying Agent be required to expend or risk its own funds in the performance of any of its duties pursuant
to this Appendix 1, or be obligated to take any legal or other action which might in its judgment involve or cause it to incur any expense or liability unless it shall have been furnished with acceptable indemnification. 

The Company agrees to instruct the Trustee or Paying Agent in writing with respect to any certifications that may be required under Spanish
law, and the Trustee or Paying Agent acknowledges that this Appendix 1 shall constitute an instruction in this regard, unless otherwise instructed in writing by the Company. 
  

	 	2.	 Failure to deliver the Payment Information Certificate: In the event that the Trustee or Paying Agent
fails or for any reason is unable to deliver a timely, duly completed Payment Information Certificate as described above to the Company in respect of a payment of income under the Contingent Convertible Capital Securities, the Trustee or Paying
Agent shall withhold Spanish income tax on behalf of the Company from the relevant payment at the then-applicable rate (currently set at 19%). 

	 	3.	 If, after the relevant payment date but before the 10th day of the month immediately following the relevant
payment date the Trustee or Paying Agent provides the duly completed Payment Information Certificate to the Company, then the Company shall instruct the Trustee or Paying Agent to immediately transfer the amounts withheld in respect of the relevant
payment pursuant to paragraph 2 above by way of reimbursement of the amounts withheld on the relevant payment date and completion of the corresponding income payment in respect of payments under the Contingent Convertible Capital Securities.

  

	 	4.	 If the Trustee or Paying Agent fails or for any reason is unable to submit a duly completed and executed
Payment Information Certificate to the Company by the 10th day of the month immediately following the relevant payment date, the Trustee or Paying Agent shall immediately return (but in any event no later than the 10th day of the month immediately
following the relevant payment date) to the Company any remaining amount of the 19% tax withheld in respect of the relevant payment, and investors will have to apply directly to the Spanish tax authorities for any refund to which they may be
entitled.

inaccurate in any way or for any losses arising by virtue thereof.

fails to determine a Successor Rate or, failing which, an Alternative Rate in accordance with this subsection prior to the relevant Reset Determination Date, the Distribution Rate applicable to the next succeeding Euro Notes Reset Period shall be
equal to the Distribution Rate last determined in relation to the Euro Notes in respect of the immediately preceding Euro Notes Reset Period. If the Company fails to make such a determination prior to the first Reset Determination Date, the
Distribution Rate shall be 4.125% per annum. For the avoidance of doubt, the contents of this subsection shall apply to the relevant next succeeding Euro Notes Reset Period only and any subsequent Euro Notes Reset Periods are subject to the

 17 

	 	(2)	 there is no Successor Rate but that there is an Alternative Rate, then such Alternative Rate and the applicable

such Adjustment Spread, then such Adjustment Spread shall be applied to the Successor Rate or the Alternative Rate (as the case may be). If the Company, following consultation with the Independent Financial Adviser and acting in good faith and in a
commercially reasonable manner, is unable to determine the quantum of, or a formula or methodology for determining, such Adjustment Spread, then the Successor Rate or Alternative Rate (as applicable) will apply without an Adjustment Spread.

and the Company, following consultation with the Independent Financial Adviser and acting in good faith and in a commercially reasonable manner, determines (i) that Benchmark Amendments are necessary and (ii) the terms of the Benchmark

nor any Adjustment Spread applied, nor will any Benchmark Amendments be made, if and to the extent that, in the determination of the Company, the same could reasonably be expected to prejudice the qualification of the Euro Notes as Tier 1 Capital.

  
 18 

	 	(ix)	 Any Successor Rate, Alternative Rate, Adjustment Spread and the specific terms of any Benchmark Amendments,
determined under this subsection will be notified promptly by the Company to the Trustee, the Calculation Agent, the Paying and Conversion Agent and to holders of Euro Notes in accordance with Section 1.05 of the Contingent Convertible Capital
Securities Indenture. Such notice shall be irrevocable and shall specify the effective date of the Benchmark Amendments, if any.

fallback provisions otherwise provided for herein will continue to apply unless and until a Benchmark Event has occurred.

 This Dollar Note is one of the series designated on the face hereof, initially limited in aggregate

For the avoidance of doubt, the potential write-down or cancellation of all or a portion of the Liquidation Preference of—or
Distributions on—this Dollar Note or the conversion of this Dollar Note into Common Equity Tier 1 instruments, other security or other obligations in connection with the exercise of any Bail-in Power by
the Relevant Resolution Authority is separate and distinct from a conversion following a Trigger Event although these events may occur consecutively. Neither a reduction or cancellation, in part or in full of the Amounts Due on, the conversion
thereof into another security or obligation of the Company or another person, as a result of the exercise of the Bail-in Power by the Relevant Resolution Authority with respect to the Company, nor the exercise
of the Bail-in Power by the Relevant Resolution Authority with respect to the Dollar Notes will be an Enforcement Event.

(i) the Trustee will not be required to take any further directions from the Holders of the Dollar Notes with respect to any portion of the
Dollar Notes that are written-down, converted to equity and/or cancelled under the Contingent Convertible Capital Securities Indenture, which authorizes Holders of a majority in aggregate outstanding Liquidation Preference of the outstanding Dollar
Notes to direct certain actions relating to the Dollar Notes; and 
 (ii) the Contingent Convertible Capital Securities Indenture will not
impose any duties upon the Trustee whatsoever with respect to the exercise of the Bail-in Power by the Relevant Resolution Authority; 

provided, however, that notwithstanding the exercise of the Bail-in Power by the Relevant
Resolution Authority, so long as the Dollar Notes remain outstanding, there will at all times be a Trustee for the Dollar Notes in accordance with the Contingent Convertible Capital Securities Indenture, and the resignation and/or removal of the
Trustee and the appointment of a successor Trustee will continue to be governed by the Base Indenture, including to the extent no additional supplemental indenture or amendment is agreed upon in the event the Dollar Notes remain outstanding
following the completion of the exercise of the Bail-in Power. 
 By its acquisition of this Dollar
Note, each Holder of this Dollar Note acknowledges and agrees that neither a cancellation or deemed cancellation of the Liquidation Preference or Distributions (in each case, in whole or in part), nor the exercise of the Bail-in Power by the Relevant Resolution Authority with respect to the Dollar Notes will give rise to a 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. 
 Each Holder of this Dollar Note that acquires such Dollar Note in the secondary market

on the part of such Holder. 
 Each Holder of this Dollar Note also acknowledges and agrees that the foregoing description of the Bail-in Power and its exercise is exhaustive on the matters described herein to the exclusion of any other agreements, arrangements or understandings relating to the application of any
Bail-in Power to this Dollar Note. 
 Additional terms of this Dollar Note, including but not
limited to Distributions, redemption, conversion, Enforcement Events, remedies, payment of additional amounts in respect of withholding tax, substitution and variation of this Dollar Note upon certain events, and amendment are set forth in the
Contingent Convertible Capital Securities Indenture.

The Series 11 4.125% Non-step-up Non-cumulative Contingent Convertible Perpetual Preferred Tier 1 Securities (the “Euro Notes”) shall have no fixed maturity or fixed redemption date. 

This Euro Note will accrue non-cumulative cash distributions (“Distributions”) (i) in respect of the
period from (and including) May 12, 2021 (the “Closing Date”) to (but excluding) May 12, 2028 (seven years after the Closing Date) (the “First Reset Date”) at the rate of 4.125% per

the relevant Reset Period, with such rate per annum converted to a quarterly rate in accordance with market convention (rounded to four decimal places, with 0.00005 rounded down), all as determined by the Calculation Agent on the relevant Reset

Indenture), such Distributions will be payable quarterly in arrears on February 12, May 12, August 12 and November 12 in each year (each a “Distribution Payment Date”), commencing on August 12,

 Payment of the Distributions this Euro Note will be made by wire transfer of immediately
available funds in euro, except as described below. Such payment shall be made to the Holder including through a Paying Agent of the Company for collection by the Holder. If the date for payment of any Distribution is not a Business Day, then
(subject as provided in the Contingent Convertible Capital Securities Indenture) such payment shall be made on the next succeeding Business Day with the same force and effect as if made on such date for payment, provided that no interest shall
accrue on such payment for the period from and after such payment date.

Company and so used. In such circumstances, the amount payable on any date in euro shall be calculated and converted into U.S. Dollars on the basis of the then most recently available market exchange rate for euro. Any payment in respect of this
Euro Note so made in U.S. dollars will not constitute an event of default or Enforcement Event under this Euro Note or the Contingent Convertible Capital Securities Indenture.

whatsoever, whether or not such Euro Note be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

purposes have the same effect as if set forth at this place.

Trustee referred to on the reverse hereof by manual signature, this Euro Note shall not be entitled to any benefit under the Contingent Convertible Capital Securities Indenture or be valid or obligatory for any purpose.

means Regulation (EU) 2019/877 of the European Parliament and of the Council of 20 May 2019 amending Regulation (EU) No 806/2014 as regards the loss-absorbing and recapitalization capacity of credit institutions and investment firms. 

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

For the avoidance of doubt, the potential write-down or cancellation of all or a portion of the Liquidation Preference of—or
Distributions on—this Euro Note or the conversion of this Euro Note into Common Equity Tier 1 instruments, other security or other obligations in connection with the exercise of any Bail-in Power by the
Relevant Resolution Authority is separate and distinct from a conversion following a Trigger Event although these events may occur consecutively. Neither a reduction or cancellation, in part or in full of the Amounts Due on, the conversion thereof
into another security or obligation of the Company or another person, as a result of the exercise of the Bail-in Power by the Relevant Resolution Authority with respect to the Company, nor the exercise of the Bail-in Power by the Relevant Resolution Authority with respect to the Euro Notes will be an Enforcement Event.

 Additionally, by its
acquisition of this Euro Note, each Holder of this Euro Note acknowledges and agrees that, upon the exercise of the Bail-in Power by the Relevant Resolution Authority: 

(i) the Trustee will not be required to take any further directions from the Holders of the Euro Notes with respect to any portion of the Euro
Notes that are written-down, converted to equity and/or cancelled under the Contingent Convertible Capital Securities Indenture, which authorizes Holders of a majority in aggregate outstanding Liquidation Preference of the outstanding Euro Notes to
direct certain actions relating to the Euro Notes; and 
 (ii) the Contingent Convertible Capital Securities Indenture will not impose any
duties upon the Trustee whatsoever with respect to the exercise of the Bail-in Power by the Relevant Resolution Authority; 

provided, however, that notwithstanding the exercise of the Bail-in Power by the Relevant
Resolution Authority, so long as the Euro Notes remain outstanding, there will at all times be a Trustee for the Euro Notes in accordance with the Contingent Convertible Capital Securities Indenture, and the resignation and/or removal of the Trustee
and the appointment of a successor Trustee will continue to be governed by the Base Indenture, including to the extent no additional supplemental indenture or amendment is agreed upon in the event the Euro Notes remain outstanding following the
completion of the exercise of the Bail-in Power. 
 By its acquisition of this Euro Note, each
Holder of this Euro Note acknowledges and agrees that neither a cancellation or deemed cancellation of the Liquidation Preference or Distributions (in each case, in whole or in part), nor the exercise of the
Bail-in Power by the Relevant Resolution Authority with respect to the Euro Notes will give rise to a 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. 
 Each Holder of this Euro Note that acquires this Euro Note in the secondary
