WHEREAS, the Purchaser has agreed to purchase an
aggregate of 3,200,000 Warrants (the “Sponsor Warrants”).

its shareholders having the right to exchange their Ordinary Shares for cash, securities or other property subsequent to the Company’s
completion of its initial business combination;


 


provided, however, that except
with the Company’s prior consent, in the case of clauses (a) through (e), or (g), above, the Permitted Transferee
must enter into a written agreement agreeing to be bound by these transfer restrictions and by the same agreements entered into by the
Purchaser with respect to the Sponsor Warrants (including provisions relating to voting, the trust account and liquidation distributions,
as described in the prospectus forming a part of the Company’s registration statement on Form S-1).

Section 3. Representations and Warranties of the
Purchaser.


 


As a material inducement to the Company to enter
into this Agreement and issue and sell the Sponsor Warrants to the Purchaser, the Purchaser hereby represents and warrants to the Company
(which representations and warranties shall survive the Closing Date) that:


 


(a) Organization and Requisite Authority. The Purchaser
possesses all requisite power and authority necessary to carry out the transactions contemplated by this Agreement.


 


(b) Authorization; No Breach.


 


(i) This Agreement constitutes a valid and binding
obligation of the Purchaser, enforceable in accordance with its terms, subject to bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium and other laws of general applicability relating to or affecting creditors’ rights and to general equitable principles
(whether considered in a proceeding in equity or law).


 


(ii) The execution and delivery by the Purchaser
of this Agreement and the fulfillment of and compliance with the terms hereof by the Purchaser does not and shall not as of each Closing
Date conflict with or result in a breach by the Purchaser of the terms, conditions or provisions of any agreement, instrument, order,
judgment or decree to which the Purchaser is subject.


 


(c) Investment Representations.


 


(i) The Purchaser is acquiring the Sponsor Warrants,
and, upon exercise of the Sponsor Warrants, the Ordinary Shares issuable upon such exercise (collectively, the “Securities”),
for the Purchaser’s own account, for investment purposes only and not with a view towards, or for resale in connection with, any
public sale or distribution thereof.


 


(ii) The Purchaser is an “accredited investor”
as such term is defined in Rule 501(a)(3) of Regulation D under the Securities Act of 1933, as amended (the “Securities Act”).


 (iii) The Purchaser understands that the Securities
are being offered and will be sold to it in reliance on specific exemptions from the registration requirements of the United States federal
and state securities laws and that the Company is relying upon the truth and accuracy of, and the Purchaser’s compliance with, the
representations and warranties of the Purchaser set forth herein in order to determine the availability of such exemptions and the eligibility
of the Purchaser to acquire such Securities.


 


(iv) The Purchaser decided to enter into this
Agreement not as a result of any general solicitation or general advertising within the meaning of Rule 502(c) under the Securities Act.


 






    3


     


    

 


(v) The Purchaser has been furnished with all materials
relating to the business, finances and operations of the Company and materials relating to the offer and sale of the Securities which
have been requested by the Purchaser. The Purchaser has been afforded the opportunity to ask questions of the executive officers and directors
of the Company. The Purchaser understands that its investment in the Securities involves a high degree of risk and it has sought such
accounting, legal and tax advice as it has considered necessary to make an informed investment decision with respect to the acquisition
of the Securities.


 


(vi) The Purchaser understands that no United States
federal or state agency or any other government or governmental agency has passed on or made any recommendation or endorsement of the
Securities or the fairness or suitability of the investment in the Securities by the Purchaser nor have such authorities passed upon or
endorsed the merits of the offering of the Securities.


 


(vii) The Purchaser understands that: (a) the Securities
have not been and are not being registered under the Securities Act or any state securities laws, and may not be offered for sale, sold,
assigned or transferred unless (1) in a registered transaction or (2) sold in reliance on an exemption therefrom; and (b) except
as specifically set forth in the Registration Rights Agreement, neither the Company nor any other person is under any obligation to register
the resale of the Securities under the Securities Act or any state securities laws or to comply with the terms and conditions of any exemption
thereunder. In this regard, the Purchaser understands that the Securities and Exchange Commission (the “SEC”) has taken the
position that promoters or affiliates of a blank check company and their transferees, both before and after a “business combination”,
are deemed to be “underwriters” under the Securities Act when reselling the securities of a blank check company. Based on
that position, Rule 144 adopted pursuant to the Securities Act would not be available for resale transactions of the Securities despite
technical compliance with the requirements of such Rule, and the Securities can be resold only through a registered offering or in reliance
upon another exemption from the registration requirements of the Securities Act.


 


(viii) The Purchaser has such knowledge and experience
in financial and business matters, knows of the high degree of risk associated with investments in the securities of companies in the
development stage such as the Company, is capable of evaluating the merits and risks of an investment in the Securities and is able to
bear the economic risk of an investment in the Securities in the amount contemplated hereunder for an indefinite period of time. The Purchaser
has adequate means of providing for its current financial needs and contingencies and will have no current or anticipated future needs
for liquidity which would be jeopardized by the investment in the Securities. The Purchaser can afford a complete loss of its investments
in the Securities.
