 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

C. Investment Representations. 

(i) The Purchaser is acquiring the Sponsor Warrants and, upon exercise of the Sponsor Warrants, the Shares issuable upon such exercise

 3 

 (ii) The Purchaser is an “accredited investor” as such term is defined in Rule
501(a)(3) of Regulation D. 
 (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 as a result of any general solicitation or general advertising within the meaning of
Rule 502(c) under the Securities Act of 1933, as amended (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 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 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, knowledge of the high degree of risk associated with investments in the securities of companies in the 

  
 4 

 
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. 
 Section 4. Conditions
of the Purchaser’s Obligations. The obligations of the Purchaser to purchase and pay for the Sponsor Warrants are subject to the fulfillment, on or before the Closing Dates, of each of the following conditions: 

A. Representations and Warranties. The representations and warranties of the Company contained in Section 2 shall be true and
correct at and as of the Closing Dates as though then made. 
 B. Performance. The Company shall have performed and complied with all
agreements, obligations and conditions contained in this Agreement that are required to be performed or complied with by it on or before the Closing Dates. 

C. No Injunction. No litigation, statute, rule, regulation, executive order, decree, ruling or injunction shall have been enacted,
entered, promulgated or endorsed by or in any court or governmental authority of competent jurisdiction or any self-regulatory organization having authority over the matters contemplated hereby, which prohibits the consummation of any of the
transactions contemplated by this Agreement or the Warrant Agreement. 
 D. Warrant Agreement. The Company shall have entered into a
Warrant Agreement with a warrant agent on terms satisfactory to the Purchaser. 
 Section 5. Conditions of the Company’s Obligations. The
obligations of the Company to the Purchaser under this Agreement are subject to the fulfillment, on or before the Closing Dates, of each of the following conditions: 

A. Representations and Warranties. The representations and warranties of the Purchaser contained in Section 3 shall be true and
correct at and as of the Closing Dates as though then made.

entered, promulgated or endorsed by or in any court or governmental authority of competent jurisdiction or any self-regulatory organization having authority over the matters contemplated hereby, which prohibits the consummation of any of the

Section 7. Survival of Representations and Warranties. All of the representations and warranties contained herein shall survive the Closing Dates. 

Section 8. Definitions. Terms used but not otherwise defined in this Agreement shall have the meaning assigned to such terms in the registration
statement on Form S-1 the Company plans to file with the Securities and Exchange Commission, under the Securities Act. 
 Section 9. Miscellaneous.

 A. Successors and Assigns. Except as otherwise expressly provided herein, all covenants and agreements contained in this Agreement
by or on behalf of any of the parties hereto shall bind and inure to the benefit of the respective successors of the parties hereto whether so expressed or not. Notwithstanding the foregoing or anything to the contrary herein, the parties may not
assign this Agreement, other than assignments by the Purchaser to affiliates thereof.
