 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 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 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 the 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
promulgated under to the Securities Act would not be available for resale transactions of the Securities despite technical compliance with the requirements of Rule 144 promulgated under to the Securities Act, 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 Private Warrant Agreement.
