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 Shares (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, and the
Purchaser has not experienced a disqualifying event as enumerated pursuant to Rule 506(d) 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 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
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 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 U.S. Securities
and Exchange Commission (the “SEC”) reflecting its status as an entity that is not a shell company.

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

in the Securities. The Purchaser can afford a complete loss of its investment in the Securities.
