      consistently applied, for the Company, except that there shall be assumed each
      year that there are dividends payable on each share of outstanding Series A
      Preferred Stock at the annual rate of nine
      percent (9%)
      (which
      amount of dividends, to the extent paid by the Company,
      shall be
      added back (if and to the extent previously subtracted in the calculation of
      Net
      Income in accordance with GAAP) to Net Income prior to determining if the
      Performance Thresholds (defined below) have been satisfied) and that,
      other
      than in the fiscal year (“FY08”)
      ending
      June 30, 2008 for which Net Income shall be calculated on a pre-tax
      basis,
      the
      Company’s income is subject to tax at an assumed twenty-five
      percent (25%)
      rate,
      and provided, however, that the Company’s Net Income shall be increased by any
      non-cash charges incurred as a result of the Offering (due to non-cash
      amortization on warrants and loss from change in fair value of the Warrants
      charged to the Company’s results of operation, if any, and if and to the extent
      previously subtracted in the calculation of Net Income in accordance with GAAP).
      The Company’s Net Income for FY08 and fiscal year (“FY09”)
      ending
      June 30, 2009 shall also be increased by any cash and non-cash charges related
      to the share exchange agreement dated April

        -2-

        
          

        

      

      
         

      

    

     

    5.2 The
      Company has established the following financial performance thresholds
      (collectively, the “Performance
      Thresholds”):
      (i)
      $5,200,000 of Net Income (calculated
      on a pre-tax basis solely with respect to FY08) for
      FY08
      (the
“FY08
      Threshold”),
      (ii)
      $9,000,000 of Net Income for FY09 (the “FY09
      Threshold”)
      and
      (iii) Net Income equal to or
      greater
      than the Company’s Net Income for the fiscal year ending June 30, 2009, for the
      fiscal year (“FY10”)
      ending
      June 30, 2010 (the “FY10
      Threshold”).
      The
      Company will provide the Investor Representative with its audited financial
      statements for FY08, FY09 and FY10, prepared in accordance with US GAAP,
      consistently applied with its financial statements for the fiscal year ending
      June 30, 2007, on or before September 30, 2008, September 30, 2009 and September
      30, 2010, respectively (the “Due
      Date”),
      along
      with a certification from the Company’s Chief Financial Officer calculating Net
      Income for such year as provided above, and a letter from the Company’s auditors
      confirming the accuracy of the CFO’s calculation, so as to allow the Investor
      Representative the opportunity to evaluate whether the Performance Threshold
      has
      been attained each year. 

     

    5.3 If
      the
      Company’s Net Income (as calculated pursuant to Section
      5.1
      above)
      for any one of FY08, FY09 or FY10 is less than 100% of the applicable
      Performance Threshold, respectively, then the Performance Threshold will be
      deemed not to have been achieved and all of the Escrow Shares shall be forfeited
      by the Shareholders and delivered by the Escrow Agent to the Investors (pro
      rata
      based on the number of Units purchased by each Investor in the Offering as
      shown
      on Exhibit A). The Investor Representative shall provide written instructions
      to
      the Escrow Agent, with copies to the Company and the Stockholders, instructing
      the Escrow Agent to deliver to the Investors, at the addresses set forth on
      Exhibit A, within ten (10) business days following delivery of the Investor
      Representative’s notice pursuant to this Section
      5.3,
      certificates registered in the name of each Investor, subject to Section
      5.6
      below
      and provided that the Escrow Agent has received such certificates from the
      Company’s transfer agent, evidencing the Investor’s pro rata portion of the
      Escrow Shares, and the Escrow Agent shall make such delivery to the Investors
      if
      no objection is received from the Stockholders. 

     

    5.4 If
      the
      Escrow Shares remain in the Escrow Account after the Investor Representative
      has
      had the opportunity to evaluate whether or not the Company has attained the
      FY10
      Performance Threshold, then all of the Escrow Shares remaining in the Escrow
      Account shall be delivered to the Stockholders, in proportion to the amount
      contributed by each, and the Investor Representative shall provide written
      instructions to the Escrow Agent instructing the Escrow Agent to deliver the
      Escrow Shares to the Stockholders within ten (10) business days following
      delivery of the financial statements for FY10 to the Investor
      Representative.


    
      
         

      

      
        -3-

        
          

        

      

      
         

      

    

     

    5.5 In
      the
      event that any Escrow Shares are to be delivered to the Investors pursuant
      to
      this Section
      5,
      the
      Company shall use best efforts to promptly cause the Escrow Shares to be
      delivered to the Investors, including causing its transfer agent promptly to
      issue the certificates in the names of the Investors and causing its securities
      counsel to provide any written instruction required by its transfer agent or
      the
      Escrow Agent in a timely manner so that the issuances and delivery contemplated
      above can be achieved within ten (10) business days following delivery of the
      applicable financial statements to the Investor Representative and so that
      the
      Escrow Shares can be delivered without restrictive legend so long as six (6)
      months have passed since the date of this Agreement. 

     

    5.6 Notwithstanding
      anything to the contrary herein, those Investors that became holders of
      Preferred Stock pursuant to the Offering shall be entitled to their pro rata
      portion of the Escrow Shares at the time of any distribution of Escrow Shares,
      regardless of whether they have subsequently transferred their Preferred Stock;
      provided, however, if an Investor has entered into a written agreement
      evidencing such Investor’s transfer and assignment of all its rights and
      obligations under this Agreement, and has provided written notice to the Company
      and the Escrow Agent of such transfer in accordance with Section
      14
      below (a
“Notice
      of Transfer”),
      then
      in the event that any Escrow Shares are to be delivered to the Investors in
      accordance with this Section
      5,
      the
      Company shall direct its transfer agent to issue the certificates in the names
      of the transferee(s) and the Escrow Shares shall be delivered by the Escrow
      Agent to the transferee(s) as set forth in the Investor’s Notice of Transfer.

      Federal or state securities laws and are being delivered to the Investor

      securities laws. Each Investor understands that it must bear the economic risk
      of its investment the Escrow Shares and hold such securities for an indefinite
      period of time, as such securities have not been registered under Federal or
      state securities laws and therefore cannot be sold unless subsequently

      with a view to, or for sale in connection with, any distribution thereof in
      violation of the Securities Act of 1933, as amended (the “Act”).
      Each
      Investor agrees, by acceptance of the Escrow Shares, that such shares will
      not
      be sold or otherwise transferred unless (i) a registration statement with
      respect to such transfer is effective under the Act and any applicable state
      securities laws or (ii) such sale or transfer is made pursuant to one or more
      exemptions from the Act. 


    
      
         

      

      
        -4-

        
          

        

      

      
         

      

    

     

    6.3 Each
      Investor, by its acceptance of the Escrow Shares, acknowledges that the Escrow
      Shares may not be sold, transferred, assigned or hypothecated by the Investor
      except in compliance with the provisions of the Act and the applicable state
      securities “blue sky” laws, and is so transferable only upon the books of the
      Company which it shall cause to be maintained for such purpose.

     

    7. Duration.
      This
      Agreement shall terminate on the distribution of all the Escrow Shares in
      accordance with Section
      5
      above.

     

    8. Interpleader.
      Should
      any controversy arise among the parties hereto with respect to this Agreement
      or
      with respect to the right to receive the Escrow Shares, the Escrow Agent shall
      have the right to consult counsel and/or to institute an appropriate
      interpleader action to determine the rights of the parties. The Escrow Agent
      is
      also hereby authorized to institute an appropriate interpleader action upon

      Escrow Agent. If the Escrow Agent is directed to institute an appropriate
      interpleader action, it shall institute such action not prior to thirty (30)
      days after receipt of such letter of direction and not later than sixty (60)
      days after such date. Any interpleader action instituted in accordance with

      obligations hereunder or under any such document. Except for this Agreement
      and
      instructions to the Escrow Agent pursuant to the terms of this Agreement, the
      Escrow Agent will not be obligated to recognize any agreement between or among
      any or all of the persons or entities referred to herein, notwithstanding its
      knowledge thereof. 

     

    9.2 The

      Escrow Agent will be indemnified and held harmless, jointly and severally,
      by
      the Company and the Stockholders from and against any expenses, including
