    2 

     

    

 

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 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 Sponsor Warrants and, upon exercise of the Sponsor 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
of 1933, as amended (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 did not enter into this Agreement 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.

 

    3 

     

    

 

(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 certain 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.
