warrant;


 


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 3,600,000 warrants (or 3,900,000 warrants if the over-allotment option is exercised in full) at a price of $1.00
per warrant (the “Private Placement Warrants”), each Private Placement Warrant entitling the holder to purchase one
Share at an exercise price of $11.50 per Share.

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:

Warrants”), in the same proportion as the amount of the option that is so exercised, and simultaneously with such purchase of
Additional Warrants, as payment in full for the Additional Warrants being purchased hereunder, and at least one (1) business day
prior to the Over-Allotment Closing Date, Purchaser shall pay $1.00 per Additional Warrant, up to an aggregate amount of $300,000 (the
 “Over-Allotment Purchase Price”), by wire transfer of immediately available funds or by such other method as may be
reasonably acceptable to the Company, to the Trust Account. On the Over-Allotment Closing Date, upon the payment by the Purchaser of the
Over-Allotment Purchase Price, the Company, at its option, shall deliver a certificate evidencing the Additional Warrants purchased on
such date duly registered in the Purchaser’s name to the Purchaser or effect such delivery in book-entry form.

Warrant shall have the terms set forth in a Warrant Agreement to be entered into by the Company and 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 rights agreement (the “Registration Rights Agreement”)

Shares underlying the Private Placement Warrants.


 


(iii)  Representations
and Warranties of the Company. As a material inducement to the Purchaser to enter into this Agreement and purchase the Private Placement
Warrants, the Company hereby represents and warrants to the Purchaser (which representations and warranties shall survive the Closing
Date) that:


 


D. Incorporation and Corporate
Power. The Company is a corporation duly incorporated, validly existing and in good standing under the laws of the State of Delaware

and authority necessary to carry out the transactions contemplated by this Agreement and the Warrant Agreement.

Section 2. 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
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 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.


 






    4


     


    

 


(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.
