C. Investment Representations.


 


(i) The Sponsors are
acquiring the Private Shares, for such Sponsors’ 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 Sponsors acknowledge
the sale contemplated hereby is being made in reliance on a private placement exemption pursuant to Section 4(a)(2) of
the Securities Act of 1933, as amended (the “Securities Act”).


 


(iii) The Sponsors understand
that the Private Shares are being offered and will be sold to are 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 Sponsors’
compliance with, the representations and warranties of the Sponsors set forth herein in order to determine the availability of such exemptions
and the eligibility of the Sponsors to acquire such Private Shares.


 


(iv) The Sponsors 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 Sponsors have
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 Sponsors. The Sponsors have been afforded the opportunity to ask questions
of the executive officers and directors of the Company. The Sponsors understand that its investment in the Private Shares involves a high
degree of risk and they have sought such accounting, legal and tax advice as they have considered necessary to make an informed investment
decision with respect to the acquisition of the Private Shares.


 


(vi) The Sponsors understand
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 Private Shares or the fairness or suitability of the investment in the Private Shares by the Sponsors nor have such
authorities passed upon or endorsed the merits of the offering of the Private Shares.


 


(vii) The Sponsors understand
that: (a) the Private Shares 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 Private Shares 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 Sponsors understand that the Securities and Exchange Commission
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 Private
Shares despite technical compliance with the certain requirements of such Rule, and the Private Shares can be resold only through a registered
offering or in reliance upon another exemption from the registration requirements of the Securities Act.

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, are capable of evaluating the merits and risks of an investment
in the Private Shares and are able to bear the economic risk of an investment in the Private Shares in the amount contemplated hereunder
for an indefinite period of time. The Sponsors have 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 Private Shares. The
Sponsors can afford a complete loss of their investments in the Private Shares.


 


(ix) The Sponsors understand
that the Private Shares shall bear the following legend and appropriate “stop transfer restrictions”:
