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, the Shares and Private Placement Warrants included in the Private Placement
Units and, upon exercise of such Private Placement Warrants, the Shares issuable upon such exercise (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 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 and Shareholder 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.


 


(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 Units and the Shares included in the Private Placement Units shall bear the following
legend and appropriate “stop transfer restrictions”:


 


“THE SECURITIES REPRESENTED HEREBY
HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS, AND NEITHER
THE SECURITIES NOR ANY INTEREST THEREIN MAY BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO
AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT OR SUCH LAWS OR AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT AND SUCH LAWS
WHICH, IN THE OPINION OF COUNSEL, IS AVAILABLE.


 


THE SECURITIES REPRESENTED BY THIS CERTIFICATE
ARE SUBJECT TO LOCKUP PROVISIONS AND MAY NOT BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF DURING THE TERM OF
THE LOCKUP.”

Agreement.
