whole warrant entitles the holder to purchase one Ordinary Share at an exercise price of $11.50 per Ordinary Share; and


 


The
Purchaser has agreed to purchase an aggregate of 4,000,000 warrants (or up to 4,400,000 warrants depending on the extent to which

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 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 the 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”).


 






    3


     


    

 


(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) of Regulation D under the Securities Act.


 


(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 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.

The Purchaser understands that the Sponsor Warrants shall bear the legend substantially in the form set forth in the Warrant Agreement.
