            for issuance.  Upon issuance in accordance with, and payment pursuant to, the terms hereof and the Warrant Agreement, the Purchaser will have good title to the Private Placement Warrants purchased by it and the Shares issuable upon exercise of
            such Private Placement Warrants, free and clear of all liens, claims and encumbrances of any kind, other than (i) transfer restrictions hereunder and under the other agreements contemplated hereby, (ii) transfer restrictions under federal and
            state securities laws, and (iii) liens, claims or encumbrances imposed due to the actions of the Purchaser.

        C.          Investment Representations.

         

          

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

         

          

        (iii)          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 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; (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; and (c) Rule 144 adopted pursuant to the Securities Act will not be available for resale transactions of Securities prior to a
              Business Combination and may not be available for resale transactions of Securities after a Business Combination.

         

            

        (vi)          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.
