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 Private Placement Units to the Purchaser, the Purchaser hereby represents and warrants to the Company (which representations and warranties shall survive each Closing Date) 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 each Closing Date (a) conflict with or result in a breach by the Purchaser of the terms, conditions or provisions of, (b) constitute a default under, (c) result in the creation of any lien, security interest, charge or
encumbrance upon the Purchaser’s equity or assets under, (d) result in a violation of, or (e) require authorization, consent, approval, exemption or other action by or notice or declaration to, or filing with, any court or
administrative or governmental body or agency pursuant to the Purchaser’s organizational documents in effect on the date hereof or as may be amended prior to completion of the contemplated Public Offering, or 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 Units (and the underlying securities) (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. 
 (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) 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. 
 (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 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. The Securities will bear a legend and appropriate “stop transfer” instructions (or an appropriate notation if securities are issued in book entry form) relating to the foregoing. The Purchaser further
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 Private Placement Units (and the underlying securities) until the 1-year anniversary following consummation of an Business Combination despite technical compliance with the requirements of Rule 144. 

(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.
