    2.02 No
      Violation.
      Neither
      the execution and delivery of this Agreement nor the consummation of the
      transactions contemplated hereby will constitute a violation or default under
      any term or provision of the Articles of Incorporation or Bylaws of the Company,
      or of any contract, commitment, indenture, other agreement or restriction of
      any
      kind or character to which the Company or the Seller is a party or by which
      the
      Company or the Seller is bound.

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    2.03 Authority.
       The
      Seller has the power and authority to execute and deliver this Agreement, to
      perform its obligations hereunder and to consummate the transactions
      contemplated hereby. This Agreement has been duly executed and delivered by
      the
      Seller and
      constitutes a valid and binding instrument, enforceable in accordance with
      its
      terms.

    2.04 Title
      to the Shares.
      The
      Seller is the sole legal and beneficial owner of the Shares in Blackrock and
      has

      free and clear of all liens, claims, options, charges, and encumbrances of
      whatsoever nature. The Purchaser acknowledges that the Shares being acquired
      from the Seller are restricted securities so that such Shares will have trading
      restrictions.

    2.05 Control
      Shares.
      The
      Certificates representing the Shares delivered pursuant to this Agreement are
      owned by an affiliate of the Company and accordingly are restricted securities
      as that term is defined in Rule 144 of the Securities Act of 1933 (the “Act”).
      As such, upon transfer of the Shares to the Purchaser, the Purchaser will begin
      a new holding period as set forth in Rule 144 and the Shares may not be resold
      without registration or pursuant to an exemption from registration for the
      holding period set forth in Rule 144. Accordingly, certificates issued to the
      Purchaser will contain an appropriate restrictive legend. 

    2.06 Undisclosed
      Liabilities.
      Except
      to the extent reflected in the balance sheet of the Company, the Company, as
      of
      that date, had no material liabilities or material obligations of any nature,
      whether absolute, accrued, contingent, or otherwise and whether due or to become
      due. Further, the Seller does not know or has no reasonable ground to know
      of
      any basis for the assertion against the Company of any material liability or
      material obligation as of September 30, 2007, of any nature or in any amount
      not
      fully reflected or reserved against in the financial statements.

    2.07 Tax
      Returns.
      The
      Company has duly filed all tax reports and returns required to be filed by
      it
      and has fully paid all taxes and other charges claimed to be due from it by
      federal, state, or local taxing authorities (including without limitation those
      due in respect of its properties, income, franchises, licenses, sales, and
      payrolls); there are no liens upon any of the Company’s property or assets;
      there are not now any pending questions relating to, or claims asserted for,
      taxes or assessments asserted against the Company.

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    2.08 Title
      to Properties; Encumbrances.
      The
      Company has good and marketable title to all of its properties and assets,

    2.09 No
      Claims; Indemnity.
      There
      are currently no claims or lawsuits threatened or pending against the Company
      or
      the Seller as the owner of its shares, and Seller is unaware of any conditions
      or circumstances that would lead to or justify the filing of any claim or
      lawsuit. If, after the consummation of this transaction and the transfer of
      the
      Shares from the Seller to the Purchaser any claim or lawsuit shall be filed
      against Blackrock or the Purchaser
      (as
      the
      owner of the Shares), arising out of any circumstances whatsoever prior to
      transfer of the shares,
      the
      Seller shall defend, indemnify and hold the Purchaser harmless from and against
      any and all such claims or lawsuits or any awards or judgments granted
      thereunder.

    2.10 Affiliate.
      The
      Seller is, or has been during the past ninety (90) days, an officer, director,
      10% or greater shareholder or “affiliate” of the Company, as that term is
      defined in Rule 144 promulgated under the Act.

                  warrants (the “March Warrants,” and together with the June 1st Warrants
                  and June 14th Warrants, the “Warrants”). Capitalized terms used and not
                  defined in this Amendment shall have the respective meanings set
                  forth in
                  the Purchase Agreements and

                2.

              	
                The
                  Company and the Purchasers now wish to further modify certain terms
                  of the
                  Warrants. 

              

      

       

      NOW,
        THEREFORE, in consideration of the foregoing Recitals and other good and
        valuable consideration, the receipt and sufficiency of which are hereby
        acknowledged, and intending to be legally bound, the Company and each Purchaser,
        severally and not jointly, agree as follows:

       

       

      
        	1.	
                Exercise
                  of Warrants.
                  Subject to the terms hereof, each Purchaser agrees to exercise
                  the March
                  Warrants as set forth herein. 

              

      

       

      
        	 	
                1.1

              	
                Subject
                  to the terms hereof, each Purchaser agrees to exercise (i) up to
                  50% of
                  the March Warrants issued to such Purchaser as set forth on Schedule
                  A
                  hereto on the date hereof (“Closing Date”). In consideration for such
                  exercise, upon obtaining approval of the Additional Listing Application
                  from the American Stock Exchange (“AMEX”) of the shares of Common Stock
                  underlying the Additional Warrants (as defined below), the Company
                  shall
                  issue to each Purchaser a warrant in the form of Exhibit
                  A
                  attached hereto (the “Additional Warrants”), registered in the name of
                  such Purchaser, pursuant to which such Purchaser shall have the
                  right to
                  acquire the number of shares of Common Stock equal to the number
                  of March
                  Warrants exercised on the Closing Date at an Exercise Price of
                  $7.00 per
                  share.

              

      

       

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

       

      
        	 	
                1.2

              	
                Each
                  Purchaser is also granted the right, until the later of April 15,
                  2008 and
                  30 days after the 2008 annual meeting of stockholders of the Company
                  (the
                  “Annual Meeting”) to exercise the remaining March Warrants, up to the
                  number of March Warrants, exercised on the Closing Date, and upon
                  such
                  exercise, the Purchaser shall receive an additional warrant, pursuant
                  to
                  which such Purchaser shall have the right to acquire the number
                  of shares
                  of Common Stock equal to the number of warrants exercised pursuant
                  to this
                  Section 1.2 at an Exercise Price of $7.00 per share and be in the
                  same
                  form as the Additional Warrant (the “Second Additional Warrant”). The
                  issuance of the Second Additional Warrant is contingent upon the
                  Company
                  obtaining approval by a majority of the Company’s stockholders to increase
                  the authorized shares of Common Stock by at least 10 million shares
                  prior
                  to the later of April 15, 2008 and the date of the Annual Meeting
                  (the
                  “Termination Date”). 

              

      

       

      
        	 	
                1.3

              	
                If
                  approval of the stockholders described in Section 1.2 above is
                  not
                  obtained on or before the Termination Date, then the Company grants
                  each
                  Purchaser the right, until 30 days after the Annual Meeting (the
“Rights
                  Period”) to exercise the remaining March Warrants, up to the number of
                  March Warrants exercised on the Closing Date, and receive the Second
                  Additional Warrant, to the extent that there are available authorized
                  shares of Common Stock. If there are not sufficient authorized
                  shares of
                  Common Stock to satisfy the Second Additional Warrant issuances
                  hereunder,
                  then the each Purchaser shall be limited to its pro-rata portion
                  of the
                  authorized shares available at such time. The pro-rata determination
                  shall
                  be made at the end of the Rights Period and shall consider only
                  the March
                  Warrants exercised during such
                  period.

              

      

       

      
        	 	
                1.4

              	
                For
                  the purposes of this Amendment, the shares issuable upon exercise
                  of the
                  Additional Warrant and Second Additional Warrant shall be included
                  in the
                  registration statements as provided in Section 3 below.
                  

              

      

       

      
        	2.	
                Closing.
                  Subject to the terms hereof, each Purchaser and the Company agrees
                  that
                  the closing of the issuance of the Additional Warrants (the “Closing”)
                  shall occur on the Closing Date. 

              

      

       

      
        	 	
                2.1.

              	
                On
                  the Closing Date, each Purchaser shall deliver to the Company the
                  Exercise
                  Notice required under the Warrants and the Exercise Price in immediately
                  available funds.

                Following
                  the Closing Date, the Company shall issue to each Purchaser a certificate
                  representing the number of Warrant Shares exercised under the March
                  Warrants.

                3.1

              	
                The
                  Company shall use commercially reasonable efforts to prepare and

                  all shares of Common Stock issuable under the Additional Warrants
                  as soon
                  as possible, but in no event later than 90 days after the Closing
                  Date

                The
                  Company shall use commercially reasonable efforts to prepare and

                                                        proceeding for such
                                                        purpose. The Purchasers have
                                                        not relied upon the same
                                                        legal counsel in
                                                        their review and negotiation
                                                        of this Amendment. The Company
                                                        has elected to
                                                        provide all Purchasers with
                                                        the same terms and form of
                                                        Amendment for the
                                                        convenience of the Company
                                                        and not because it was required
                                                        or requested to
                                                        do so by the Purchasers.
                                                        Each Purchaser represents
                                                        that it has been
                                                        represented by its own separate
                                                        legal counsel in its review
                                                        and
