sell to the Sponsor, and the Sponsor shall purchase from the Company, on a pro rata basis, up to 1,440,000 Private Placement Warrants

possesses all requisite corporate power and authority necessary to carry out the transactions contemplated by this Agreement and the
Warrant Agreement.

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). Upon issuance in accordance with, and payment pursuant to, the terms of the Warrant Agreement and this Agreement, the Private Placement
Warrants will constitute valid and binding obligations of the Company, enforceable in accordance with their terms as of the Closing Date.

execution and delivery by the Company of this Agreement and the Private Placement Warrants, the issuance and sale of the Private Placement
Warrants, the issuance of the Shares upon exercise of the Private Placement Warrants and the fulfillment of and compliance with the respective

and Warranties of the Purchasers. As a material inducement to the Company to enter into this Agreement and issue and sell the Private
Placement Warrants to the Purchasers, each Purchaser hereby represents and warrants to the Company (which representations and warranties

(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 (a) conflict with or result in a breach by the Purchaser of the terms, conditions or provisions

any material law, statute, rule or regulation to which the Purchaser is subject, or any agreement, instrument, order, judgment or decree
to which the Purchaser is subject, except for any filings required after the date hereof under federal or state securities laws.


 


C.            Investment Representations.


 


(i)             The
Purchaser is acquiring the Private Placement Warrants and, upon exercise of the Private Placement Warrants, the Shares issuable upon
such exercise (collectively, the “Securities”) for its 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, 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.


 






    4


     


    

 


(iv)           The
Purchaser did not decide to enter into this Agreement as a result of any general solicitation or general advertising within the meaning
of Rule 502(c) 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) subsequently registered thereunder or (2) sold
in reliance on an exemption therefrom; and (b) except as specifically set forth in the Registration and Shareholder 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 SEC 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 investments in the Securities.


 


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