Subordinated Notes Indenture unless otherwise indicated. The terms of the Subordinated Notes include those stated in the Subordinated Notes Indenture. The Subordinated Notes are subject to all such terms, and Holders are referred to the
Subordinated Notes Indenture for a statement of all such terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Subordinated Note and the terms of the Subordinated Notes Indenture, the
terms of the Subordinated Notes Indenture will control. 
 This Note is one of the series designated on the face hereof, initially limited
in aggregate principal amount to $1,500,000,000; provided, that the Company may, from time to time, without the consent of the Holders of the Subordinated Notes, issue additional Subordinated Debt Securities under the Subordinated Notes Indenture,
having the same ranking and same interest rate, maturity, redemption terms and other terms, except for the price to the public, original interest accrual date, issue date and first interest payment date, as the Subordinated Notes; provided,
however, that such additional Subordinated Notes will not have the same CUSIP, ISIN or other identifying number as the outstanding Subordinated Notes unless the additional Subordinated Notes are fungible with the Subordinated Notes for U.S. federal
income tax purposes. Any such additional Subordinated Notes, together with the Subordinated Notes, will constitute a single series of Subordinated Notes under the Subordinated Notes Indenture and shall be included in the definition of

Company, 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 obligations of the Company under the
Subordinated Notes.

acquisition of a Subordinated Note, will be deemed to have agreed to the above described subordination. 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 Subordinated Notes. In addition, each Holder of the Subordinated Notes by his or her acquisition of the Subordinated Notes authorizes and directs the

purchase additional units), or $1.50 per Warrant, in a private placement that shall close simultaneously with the
consummation of the Public Offering (including Ordinary Shares issuable upon conversion thereof); (iv) “Public

2.                 
Representations and Warranties.

 

(a)              
Insider represents and warrants to the Company that she has the full right and power, without violating any agreement
to which she is bound (including, without limitation, any non-competition or non-solicitation agreement with any employer or former
employer), to enter into this Letter Agreement, as applicable, and to serve as a director on the Company’s Board of Directors
(the “Board”), and the Insider hereby consents to being named in the public filings of the Company as director of the
Company.

 

(b)              
The Insider represents and warrants that the Insider’s questionnaire furnished to the Company is true and accurate
in all material respects. The Insider represents and warrants that such Insider is not subject to, or a respondent in any legal
action for, any injunction, cease-and-desist order or order or stipulation to desist or refrain from any act or practice relating
to the offering of securities in any jurisdiction; such Insider has never been convicted of, or pleaded guilty to, any crime (i)
involving fraud, (ii) relating to any financial transaction or handling of funds of another person, or (iii) pertaining to any
dealings in any securities and such Insider is not currently a defendant in any such criminal proceeding; and such Insider has
never been suspended or expelled from membership in any securities or commodities exchange or association or had a securities or
commodities license or registration denied, suspended or revoked.

 

3.                 
Business Combination Vote. The Insider agrees that if the Company seeks shareholder approval of a proposed
initial Business Combination, then in connection with such proposed initial Business Combination, she shall vote all Founder Shares
and any Public Shares held by her in favor of such proposed initial Business Combination (including any proposals recommended by
the Board in connection with such Business Combination) and not redeem any Public Shares held by her in connection with such shareholder
approval.

 

4.                 
Failure to Consummate a Business Combination; Trust Account Waiver.

 

(a)               The
Insider hereby agrees that in the event that the Company fails to consummate its initial Business Combination within the time
period set forth in the Charter, the Insider shall take all reasonable steps to cause the Company to (i) cease all operations
except for the purpose of winding up; (ii) as promptly as reasonably possible, but not more than 10 business days thereafter,
redeem 100% of the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the
Trust Account, including interest earned on the funds held in the Trust Account and not previously release to the Company to
pay income taxes (which interest shall be net of taxed payable and less up to $100,000 of interest to pay dissolution
expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish Public
Shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any); and
(iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining
shareholders and the Board, liquidate and dissolve, subject in the case of clauses (ii) and (iii) to the Company’s
obligations under Cayman Islands law to provide for claims of creditors and in all cases subject to the other requirements of
applicable law. The Insider agrees not to propose any amendment to the Charter (i) that would modify the substance or timing
of the Company’s obligation to allow redemptions in connection with the Company’s initial Business Combination or
to redeem 100% of the Public Shares if it does not complete an initial Business Combination within the time period required
by the Charter, or (ii) with respect to any other provision relating to the rights of Public Shareholders or pre-initial
Business Combination activity unless the Company provides its Public Shareholders with the opportunity to redeem their Public
Shares upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on
deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to
the Company to pay taxes (which interest shall be net of taxes payable), if any, divided by the number of then-outstanding
Public Shares.

 

    2

     

    

 

(b)              
The Insider acknowledges that she has no right, title, interest or claim of any kind in or to any monies held in
the Trust Account or any other asset of the Company as a result of any liquidation of the Company with respect to the Founder Shares
held by her, if any. The Insider hereby further waives, with respect to any Founder Shares and Public Shares held by her, any redemption
rights she may have in connection with the consummation of a Business Combination, including, without limitation, any such rights
available in the context of a shareholder vote to approve such Business Combination or a shareholder vote to approve an amendment
to the Charter (i) that would modify the substance or timing of the Company’s obligation to allow redemptions in connection
with the Company’s initial Business Combination or to redeem 100% of the Public Shares if it does not complete an initial
Business Combination within the time period required by the Charter, or (ii) with respect to any other provision relating to the
rights of Public Shareholders or pre-initial Business Combination activity (although the Insider shall be entitled to liquidation
rights with respect to any Public Shares she holds if the Company fails to consummate a Business Combination within the required
time period set forth in the Charter).

 

5.                 
Lock-up; Transfer Restrictions.

 

(a)              
The Insider agrees that she shall not Transfer any Founder Shares (the “Founder Shares Lock-up”) until

of an initial Business Combination on which the Company completes a liquidation, merger, share exchange or other similar transaction
that results in all of the Company’s shareholders having the right to exchange their Ordinary Shares for cash, securities
or other property (the “Founder Shares Lock-up Period”). Notwithstanding the foregoing, if, subsequent to a Business
Combination, the closing price of the Ordinary Shares equals or exceeds $12.00 per share (as adjusted for share sub-divisions,
share capitalizations, share consolidations, reorganizations, recapitalizations and the like) for any 20 trading days within a
30-trading day period commencing at least 150 days after the Company’s initial Business Combination, the Founder Shares shall
be released from the Founder Shares Lock-up.

Notwithstanding the provisions set forth in paragraphs 5(a) and (b), Transfers of the Founder Shares, Private Placement
Warrants and Ordinary Shares underlying the Private Placement Warrants are permitted (a) to the Company’s officers or directors,
any affiliate or family member of any of the Company’s officers or directors, any affiliate of the Sponsor or to any member
of the Sponsor or any of their affiliates; (b) in the case of an individual, as a gift to a member of one of the individual’s
immediate family or to a trust, the beneficiary of which is a member of the individual’s immediate family, an affiliate of
such person or to a charitable organization; (c) in the case of an individual, by virtue of laws of descent and distribution upon
death of the individual; (d) in the case of an individual, pursuant to a qualified domestic relations order; (e) by private sales
or transfers made in connection with any forward purchase agreement or similar arrangement or in connection with the consummation
of a Business Combination at prices no greater than the price at which the Ordinary Shares or Warrants were originally purchased;
(f) by virtue of the laws of the Cayman Islands or the Sponsor’s organizational documents upon dissolution of the Sponsor;
(g) in the event of the Company’s liquidation prior to the completion of a Business Combination; or (i) in the event of,
subsequent to the completion of an initial Business Combination, the Company’s completion of a liquidation, merger, share
exchange or other similar transaction which results in all of the Company’s Public Shareholders having the right to exchange
their Ordinary Shares for cash, securities or other property; provided, however, that in the case of clauses (a) through (f) these
permitted transferees must enter into a written agreement agreeing to be bound by these transfer restrictions.

be irreparably injured in the event of a breach by the Insider of her obligations, as applicable under paragraphs 3, 4, 5 and 7;

relief, in addition to any other remedy that such party may have in law or in equity, in the event of such breach.

Payments by the Company. Except as disclosed in the Prospectus, no director nor any affiliate of the director
shall receive from the Company any finder’s fee, reimbursement, consulting fee, monies in respect of any payment of a loan
or other compensation prior to, or in connection with, any services rendered in order to effectuate the consummation of the Company’s
initial Business Combination (regardless of the type of transaction that it is).

 

8.                  Director
and Officer Liability Insurance. The Company will maintain an insurance policy or policies providing directors’ and
officers’ liability insurance, and the Insider shall be covered by such policy or policies, in accordance with its or
their terms, to the maximum extent of the coverage available for any of the Company’s directors or officers.
