Section
3.3Investment Representations.

 

(a)       The
Buyer is an “accredited investor” as defined in Rule 501 of Regulation D under the Securities Act.

 

(b)       The
Buyer has received, has thoroughly read, is familiar with and understands the contents of this Agreement.

 

(c)       The
Buyer hereby acknowledges that an investment in the Shares involves certain significant risks. The Buyer acknowledges that there
is a substantial risk that it will lose all or a portion of its investment and that it is financially capable of bearing the risk
of such investment for an indefinite period of time. The Buyer has no need for liquidity in its investment in the Shares for the
foreseeable future and is able to bear the risk of that investment for an indefinite period. The Buyer understands that there
presently is no public market for the Shares and none is anticipated to develop in the foreseeable future. The Buyer’s present
financial condition is such that the Buyer is under no present or contemplated future need to dispose of any portion of the Shares
subscribed for hereby to satisfy any existing or contemplated undertaking, need or indebtedness. The Buyer’s overall commitment
to investments which are not readily marketable is not disproportionate to its net worth and the investment in the Company will
not cause such overall commitment to become excessive.

 

(d)       The
Buyer acknowledges that the Shares have not been and will not be registered under the Securities Act, or any state securities
act, and are being sold on the basis of exemptions from registration under the Securities Act and applicable state securities
acts, except those state securities acts that require registration of the Shares thereunder. Reliance on such exemptions, where
applicable, is predicated in part on the accuracy of the Buyer’s representations and warranties set forth herein. The Buyer
acknowledges and hereby agrees that the Shares will not be transferable under any circumstances unless the Buyer either registers
the Shares in accordance with federal and state securities laws or finds and complies with an available exemption under such laws.
Accordingly, the Buyer hereby acknowledges that there can be no assurance that it will be able to liquidate its investment in
the Company.

 

(e)       There
are substantial risk factors pertaining to an investment in the Company. The Buyer acknowledges that it has read the information
set forth above regarding certain of such risks and is familiar with the nature and scope of all such risks, including, without
limitation, risks arising from the fact that the Company is an entity with limited operating history and financial resources;
and the Buyer is fully able to bear the economic risks of such investment for an indefinite period, and can afford a complete
loss thereof.

 

(f)       The
Buyer has been given the opportunity to (i) ask questions of and receive answers from the Company and its designated representatives
concerning the terms and conditions of the offering, the Company and the business and financial condition of the Company and (ii)
obtain any additional information that the Company possesses or can acquire without unreasonable effort or expense that is necessary
to assist the Buyer in evaluating the advisability of the purchase of the Shares and an investment in the Company. The Buyer further
represents and warrants that, prior to signing this Agreement, it has asked such questions, received such answers and obtained
such information as it has deemed necessary or advisable to evaluate the merits and risks of the purchase of the Shares and an
investment in the Company. The Buyer is not relying on any oral representation made by any person as to the Company or its operations,
financial condition or prospects.

 

    	 	3	 

     

    

 

(g)       The
Buyer understands that no federal, state or other governmental authority has made any recommendation, findings or determination
relating to the merits of an investment in the Company.

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. 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 a 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.

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.
