    Pursuant
      to the Letter Agreement, the undersigned holder of 3,500,000 shares of the
      common stock of the Company (“Common

      to pay to the Company an amount equal to $1,750,000 within ninety (90) days
      of
      the Closing (as defined in the Stock Exchange Agreement), or in the alternative,
      tender to the Company for cancellation two (2) shares of Common Stock for every
      $1 not paid, subject to the terms and conditions of the Letter Agreement. The
      Holder and the Company wish to amend certain terms of the Letter Agreement
      as
      specifically set forth herein.

                Stock
                is now referred to as Company Common Stock to reflect the closing
                of the
                stock exchange as set forth in the Stock Exchange
                Agreement.

              The
                third paragraph of the Letter Agreement is hereby modified and restated
                to

    “The
      Holder understands that delivery of this letter agreement (this “Agreement”)
      is a
      condition to closing the Stock Exchange Agreement. This Agreement sets forth
      the
      terms and conditions under which the Holder agrees to pay to Company an amount
      equal to $1,400,000 within one hundred eighty (180) days of the Closing (as
      defined in the Stock Exchange Agreement), or in the alternative, tender to
      Company for cancellation two and one-half (2 1/2) shares of Company Common
      Stock
      for every $1 not paid. All dollar amounts stated in this Agreement are in United
      States Dollars.”


    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    


    
      	 	
              (b)

            	
              Paragraph
                1
                of
                the Letter Agreement is hereby modified and restated to read as
                follows:

            


    

    


    “Agreement
      to Pay; Forfeiture of Shares; Waiver.
      On or
      before November 15, 2008, or such other date as the Company and the Holder
      agree
      (such date to be referred to herein as the “Payment
      Date”),
      Holder
      shall pay to Compamy $1,400,000 ( the “Payment”).
      In
      the event Company does not receive all of the Payment on or before the Payment
      Date, Holder shall tender its shares of Company Common Stock to Company no
      later
      than the Payment Date for immediate cancellation by Company at a rate of two
      and
      one-half (2 1/2) shares of Company Common Stock for every $1 not received by
      Company on or before the Payment Date. Holder agrees that, in the event it
      tenders its shares of Company Common Stock to Company for cancellation, upon
      tendering the shares, Holder will not have any claim
      against Company, or any affiliate of Company or its predecessors, including
      but
      not limited to, any claim for stock or other equity interests of any kind,
      or
      any claim based upon breach of contract, discrimination, violation of public
      policy, negligence and/or any other common law, statutory or other claim
      whatsoever, and Holder shall not bring any claim or commence any litigation
      against Company or any affiliate of Company or any of its affiliates or
      precessors relating to any of the foregoing.”

    


    
      	 	
              (c)
                

            	
              Clause
                (b) of Paragraph
                2
                of
                the Letter Agreement is hereby modified and restated to read as
                follows:

            


    

    


    “(b)
      if
      Company receives only a portion of the Payment, Holder shall deliver to Company
      certificates representing that number of shares of Company Common Stock equal
      to
      two and one-half (2 1/2) shares of Company Common Stock for each $1 not paid
      to
      Company in accordance with this Agreement.” 

    


    3.  
       Representations
      and Warranties of Holder.
      Holder
      has requested this Modification based on Holder’s need to complete business
      transactions unrelated to the Company and the Common Stock. Holder represents
      and warrants that he will obtain the funds to make the payment required herein
      from those business transactions and that he will not be engaged in the sale
      of
      any shares of the Common Stock prior to the Payment Date. Holder and the Company
      agree that payments may be made by the Holder in installments prior to the
      Payment Date.

     

    4.  
       Governing
      Law.
      THIS
      MODIFICATION SHALL BE GOVERNED AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL
      LAWS AND DECISIONS OF THE STATE OF COLORADO, WITHOUT REGARD TO THE CONFLICT
      OF
      LAWS PROVISIONS THEREOF.

     

    5.  
       Continued
      Validity.
      The
      Letter Agreement (including the provisions of the Agreement not modified
      hereby), as modified by this Modification, shall remain in full force and effect
      following the execution of this Modification.

    6.  
       Counterparts.
      This
      Modification may be executed in any number of counterparts and by the different
      parties hereto on separate counterparts, and each such counterpart shall be
      deemed to be an original, but all such counterparts shall together constitute
      one and the same agreement. The exchange of copies of this Modification and
      of
      signature pages by facsimile transmission shall constitute effective execution
      and delivery of this Modification as to the parties and may be used in lieu
      of
      the original Letter Agreement for all purposes. Signatures of the parties
      transmitted by facsimile shall be deemed to be their original signatures of
      all
      purposes.
