B.
Authorization; No Breach.


 


(i)
This Agreement constitutes a valid and binding obligation of such 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 such Purchaser of this Agreement and the fulfillment of and compliance with the terms hereof by such Purchaser
does not and shall not as of the Closing Date conflict with or result in a breach by such Purchaser of the terms, conditions or provisions
of any agreement, instrument, order, judgment or decree to which such Purchaser is subject.


 


C.
Investment Representations.


 


(i)
Such Purchaser is acquiring Private Placement Warrants as described above and, upon exercise of such Private Placement Warrants, the
Ordinary Shares issuable upon such exercise (collectively, the “Securities”), for such 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)
Such 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”), and each Purchaser has not experienced a disqualifying event as enumerated
pursuant to Rule 506(d) of Regulation D under the Securities Act.


 


(iii)
Such Purchaser understands that the Securities are being offered and will be sold to it, him or her 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 such Purchaser’s compliance with, the representations and warranties of such Purchaser set forth herein in
order to determine the availability of such exemptions and the eligibility of such Purchaser to acquire such Securities.


 


(iv)
Such 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)
Such 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 such Purchaser. Such Purchaser has been afforded the opportunity
to ask questions of the executive officers and directors of the Company. Such 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.


 




    	 	4	 



     


    

 


(vi)
Such 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 such
Purchaser nor have such authorities passed upon or endorsed the merits of the offering of the Securities.


  


(vii) Such 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, such Purchaser understands that 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)
Such 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. Such 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. Such
Purchaser can afford a complete loss of its investments in the Securities.


 


(ix)
Such Purchaser understands that the Private Placement Warrants shall bear the legend substantially in the form set forth in the Warrant
Agreement.

4. Conditions of the Purchasers’ Obligations. The obligations of each of the Purchasers to purchase and pay for the Private
Placement Warrants are subject to the fulfillment, on or before the Closing Date, of each of the following conditions:
