      NOW, THEREFORE, in consideration of the premises, representations, warranties and the mutual covenants contained in this Agreement, and for other good and
        valuable consideration, the receipt, sufficiency and adequacy of which are hereby acknowledged, the parties hereto, intending to be legally bound, hereby agree as follows:

       

      Section 1. Assignment of Securities. The Initial Purchaser hereby sells, assigns and transfers to the Sponsor, and the Sponsor hereby purchases, the
        Subject Shares for an aggregate purchase price of $25,000.00 which was previously paid in connection with the Subscription Agreement by the Initial Purchaser;

       

      Section 2. No Conflicts. Each party represents and warrants that neither the execution and delivery of this Agreement by such party, nor the
        consummation or performance by such party of any of the transactions contemplated hereby, will with or without notice or lapse of time, constitute, create or result in a breach or violation of, default under, loss of benefit or right under or
        acceleration of performance of any obligation required under any agreement to which it is a party.

       

      

      Section 3. Representations of the Sponsor.

       

      (a) The Sponsor represents and warrants to the Initial Purchaser that, at the time the buy order for the Shares was originated, Sponsor was outside the
        United States and was not a U.S. person (and was not purchasing for the account or benefit of a U.S. person) within the meaning of Regulation S under the U.S. Securities Act of 1933, as amended (the “Act”).

       

      
        
          


      

      (b) The Sponsor acknowledges, represents and agrees with the Initial Purchaser that the Shares are being offered for sale in a transaction not involving
        any public offering in the United States within the meaning of the Act. The Shares have not been registered under the Act or any U.S. securities laws and they are being offered for sale in a transaction not requiring registration under the Act. The
        Shares may not be reoffered, resold, pledged or otherwise transferred except (i) to a person whom the Sponsor reasonably believes is a qualified institutional buyer in a transaction meeting the requirements of Rule 144A under the Act; (ii) in an
        offshore transaction complying with Rule 903 of Regulation S under the Act; (iii) pursuant to an exemption from registration under the Act provided by Rule 144 thereunder if available (“Rule 144”); (iv) to an
        institutional “accredited investor” (as defined in Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Act) that, prior to such transfer, furnishes the Company’s transfer agent with a signed letter containing certain representations and
        agreements relating to the transfer of the Shares and, if such transfer is in respect of an aggregate principal amount of notes less than $250,000, an opinion of counsel acceptable to the Company, if the Company so requests, that the transfer is in
        compliance with the Act; (v) in accordance with another exemption from the registration requirements of the Act (and based upon an opinion of counsel acceptable to the Company, if the Company so requests); (vi) to the Company; or (vii) pursuant to
        an effective registration statement under the Act, and, in each case, in accordance with all applicable U.S. state securities laws. The Sponsor will notify any subsequent purchaser from it of the resale restrictions set forth in the preceding
        sentence. Sponsor acknowledges that no representation is being made as to the availability of the exemption provided by Rule 144 for resales of the Shares.

       

      (c) Sponsor acknowledges that it has had access to such financial and other information concerning the Company and the Shares as it has deemed necessary in
        connection with its decision to purchase any of the Shares, including any opportunity to ask questions of and request information from the Company. Sponsor represents that it has not relied upon the Initial Purchaser or any information provided by
        it in deciding to purchase the Shares.

       

      (d) Sponsor understands that, until registered under the Act, the Shares will bear a legend to the effect set forth in clause (b) unless otherwise agreed
        by the Company.

      

      

      Section 4. Assignment of Rights. No party hereto may assign either this Agreement or any of its rights, interests, or obligations hereunder without
        the prior written approval of the other party.

       

      Section 5. Miscellaneous. This Agreement, together with the certificates, documents, instruments and writings that are delivered pursuant hereto,
        constitutes the entire agreement and understanding of the parties hereto in respect of its subject matter. This Agreement may be executed in two or more counterparts, each of which will be deemed an original but all of which together will
        constitute one and the same instrument. This Agreement may not be amended, modified or waived as to any particular provision, except by a written instrument executed by all parties hereto.

      

      

      Section 6. Governing Law. This Agreement and the rights and obligations of the parties hereunder shall be construed in accordance with and governed
        by the laws of New York applicable to contracts wholly performed within the borders of such state, without giving effect to the conflict of law principles thereof.
