      follows:

     

    3.1
      Transfer
      of Shares.
      The
      Shares have not been registered under the Securities Act and cannot be sold
      or
      otherwise transferred without an effective registration or an exemption
      therefrom, and as of the date of this Agreement, may not be sold pursuant to
      the
      exemptions provided by Section 4(1) of the Securities Act or Rule 144 under
      the
      Securities Act, in accordance with the letter from Richard K. Wulff,
Chief
      of
      the Office of Small Business Policy of the Securities and Exchange Commission’s
      Division of Corporation Finance,
      to Ken
      Worm of NASD Regulation, Inc., dated January 21, 2000.

    


    3.2
      Experience.
      The
      undersigned has such knowledge and experience in financial and business matters
      that the undersigned is capable of evaluating the merits and risks of investment
      in the Company and of making an informed investment decision. The undersigned
      has adequate means of providing for the undersigned's current needs and possible
      future contingencies and the undersigned has no need, and anticipates no need
      in
      the foreseeable future, to sell the Shares for which the undersigned subscribes.
      The undersigned is able to bear the economic risks of this investment and,
      consequently, without limiting the generality of the foregoing, the undersigned
      is able to hold the Shares for an indefinite period of time and has sufficient
      net worth to sustain a loss of the undersigned's entire investment in the
      Company in the event such loss should occur. Except as otherwise indicated
      herein, the undersigned is the sole party in interest as to its investment
      in
      the Company, and it is acquiring the Shares solely for investment for the
      undersigned's own account and has no present agreement, understanding or
      arrangement to subdivide, sell, assign, transfer or otherwise dispose of all
      or
      any part of the Shares subscribed for to any other person. 

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

     

    3.3
      Investment;
      Access to Data.
      The
      undersigned has carefully reviewed and understands the risks of, and other
      considerations relating to, a purchase of the Common Stock and an investment
      in
      the Company. The undersigned has been furnished materials relating to the
      Company, the private placement of the Common Stock or anything else that it
      has
      requested and has been afforded the opportunity to ask questions and receive
      answers concerning the terms and conditions of the offering and obtain any
      additional information which the Company possesses or can acquire without
      unreasonable effort or expense. Representatives of the Company have answered
      all
      inquiries that the undersigned has made of them concerning the Company, or
      any
      other matters relating to the formation and operation of the Company and the
      offering and sale of the Common Stock. The
      undersigned has not been furnished any offering literature other than the
      materials that the Company may have provided at the request of the undersigned;
      and the undersigned has relied only on such information furnished or made
      available to the undersigned by the Company as described in this Section. The
      undersigned is acquiring the Shares for investment for the undersigned's own
      account, not as a nominee or agent and not with the view to, or for resale
      in
      connection with, any distribution thereof. The undersigned acknowledges that
      the
      Company is a start-up company with no current operations, assets or operating
      history, which may possibly cause a loss of Purchaser’s entire investment in the
      Company. 

    


    3.4

      (a)
      This Agreement, upon execution and delivery thereof, will be a valid and binding

      laws of general application affecting enforcement of creditors' rights
      generally.

    


    (b)
      The
      execution, delivery and performance by Purchaser of this Agreement and
      compliance therewith and the purchase and sale of the Shares will not result
      in
      a violation of and will not conflict with, or result in a breach of, any of
      the
      terms of, or constitute a default under, any provision of state or Federal
      law
      to which Purchaser is subject, or any mortgage, indenture, agreement,
