purchase the Warrants, the Company hereby represents and warrants to the Purchaser (which representations and warranties shall survive

Organization and Corporate Power. The Company is a corporation duly organized, validly existing and in good standing under
the laws of the Cayman Islands and is qualified to do business in every jurisdiction in which the failure to so qualify would reasonably
be expected to have a material adverse effect on the financial condition, operating results or assets of the Company. The Company possesses

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
Warrants to the Purchaser, the Purchaser hereby represents and warrants to the Company (which representations and warranties shall
survive the Closing Dates) 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 the Closing Dates 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 Warrants and, upon exercise of the Warrants, the 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 and the Purchaser has not experienced a disqualifying event as enumerated pursuant to Rule 506(d) of Regulation D under 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’s decision to enter into this Agreement was not the a result of any general solicitation or general advertising
within the meaning of Rule 502(c) under the Securities Act.


 






    4


     


    

 


(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) subsequently registered thereunder 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 has taken the position that promoters or affiliates of a blank check company and their transferees, both before and after an
initial 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, knowledge 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 investment in the Securities.
