Each whole warrant entitles the holder to purchase one Share at an exercise price of $11.50 per Share; and 

The Purchaser has agreed to purchase an aggregate of 6,817,560 warrants (or up to 7,462,560 warrants to the extent the underwriters’
over-allotment option is exercised) (the “Private Placement Warrants”), each Private Placement Warrant entitling the holder to purchase one Share at an exercise price of $11.50 per Share. 

NOW THEREFORE, in consideration of the mutual promises contained in this Agreement and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties to this Agreement hereby, intending legally to be bound, agree as follows:

Continental in connection with the Public Offering (the “Warrant Agreement”). Such terms include the fact that the Private Placement Warrants shall not be transferable, assignable or salable until 30 days after the completion of an
initial business combination, subject to certain exceptions set forth in the Warrant Agreement. 
 (ii) On or prior to the
Effective Date, the Company and the Purchaser shall enter into a registration and shareholder rights agreement (the “Registration and Shareholder Rights Agreement”) pursuant to which the Company will grant certain registration
rights to the Purchaser relating to the Private Placement Warrants and the Shares underlying the Private Placement Warrants. 

Section 2. Representations and Warranties of the Company. As a material inducement to the Purchaser to enter

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 Warrants to the Purchaser, the Purchaser hereby represents and warrants to the Company (which representations and warranties shall survive the applicable 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 the applicable Closing Date 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 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 of 1933, as amended (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) 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. The Private Placement Warrants will bear a legend and appropriate “stop transfer” instructions (or an appropriate notation if the warrants are issued
in book entry form) relating to the foregoing. The Purchaser further understands that the Securities and Exchange Commission (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 until the one-year anniversary following consummation of an initial business combination despite technical compliance with the
requirements of such Rule. 
 (viii) The Purchaser has such knowledge and experience in financial and business matters, knows
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 investment in the Securities.
