      and Warranties of the Seller .
      The
      Seller represents and warrants to the Company as follows:




(a)  Seller
      is
      validly existing and is in good standing under the laws of the jurisdiction
      of
      its organization.









(b)  Seller
      has full legal capacity, power and authority to execute and deliver this
      Agreement and to consummate the transactions contemplated hereby. The execution
      and delivery of this Agreement and the consummation of the transactions
      contemplated hereby by Seller have been duly and validly authorized by all
      necessary action on the part of Seller, and no other proceedings on the part
      of
      Seller are necessary to authorize this Agreement or to consummate the
      transactions contemplated hereby.




(c)  This
      Agreement has been duly and validly executed and delivered by Seller and
      constitutes a valid and binding agreement of Seller, enforceable against Seller
      in accordance with its terms.




(d)  Seller
      owns of record the Purchase Option and is assigning it to the Company free
      and
      clear of all “adverse claims” (as such term is defined in
      Section 8-102(a)(1) of the Uniform Commercial Code of the State of New
      York).




(e)  The
      execution and delivery of this Agreement by Seller does not, and the performance
      of the terms of this Agreement by Seller will not, (i) require Seller to obtain
      the consent or approval of, or make any filing with or notification to, any
      governmental or regulatory authority, domestic or foreign; (ii) conflict with
      or
      violate the organizational documents of Seller; (iii) require the consent or
      approval of any other person pursuant to any agreement, obligation or instrument
      binding on Seller or its properties and assets; (iv) conflict with or violate

      or

      acknowledges that (i) the Company may have possession of material, non-public

“ Excluded
      Information ”)
      and
      the Company is not sharing the Excluded Information with Seller; (ii) Seller
      does not possess or have access to the Excluded Information, and, as a
      consequence, there may exist a disparity of information between the Company
      and
      the Seller with respect to the Company and its securities, including the
      Purchase Option; (iii) the Excluded Information could be indicative of a value
      of the Purchase Option that is higher than the Purchase Price reflected in
      the
      sale or could otherwise be adverse to the Seller; and (iv) the Excluded
      Information may be material to Seller’s decision to sell the Purchase
      Option.




(g)  Seller
      has not requested the Excluded Information and agrees that the Company shall
      not
      be obligated to disclose any Excluded Information to the Seller and that the
      Company shall have no liability with respect to any non-disclosure of the
      Excluded Information. As a condition to the Company’s agreement to buy the
      Purchase Option, to the fullest extent permitted by law, the Seller hereby
      releases and waives any and all claims, causes of action, actions, proceedings,
      suits, judgments, liens and executions, claims and causes of action, whether
      known or unknown, now or hereafter arising against the Company, based upon
      or
      relating to such non-disclosure or the Seller’s failure to review the Excluded
      Information and further covenants not to sue the Company for any loss, damage
      or
      liability arising from or relating to the sale of the Purchase Option.
