extent the over-allotment option in connection with the Public Offering 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.

are hereby acknowledged, the parties to this Agreement hereby, intending legally to be bound, agree as follows:

C.           Investment
Representations.


 


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

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 of the Securities
Act of 1933, as amended (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

(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) 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. While the Purchaser understands
that Rule 144 under the Securities Act is not available for the resale of securities initially issued by shell companies (other
than business combination related shell companies) or issuers that have been at any time previously a shell company, the Purchaser
understands that Rule 144 includes an exception to this prohibition if the following conditions are met: (i) the issuer
of the securities that was formerly a shell company has ceased to be a shell company; (ii) the issuer of the securities is
subject to the reporting requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934, as amended (the
 “Exchange Act”); (iii) the issuer of the securities has filed all Exchange Act reports and material required
to be filed, as applicable, during the preceding 12 months (or such shorter period that the issuer was required to file such reports
and materials), other than Form 8-K reports; and (iv) at least one year has elapsed from the time that the issuer filed
current Form 10 type information with the SEC reflecting its status as an entity that is not a shell company.


 


(viii)           The
Purchaser has knowledge and experience in financial and business matters, understands 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.
