    CLASS
      A
      WARRANT

    

    THIS
      CERTIFIES THAT, for value received ____________is the registered holder of
      a
      Class A Warrant or Class A Warrants expiring ________, 2013 (the “Warrant”) to
      purchase one fully paid and non-assessable share of Common Stock, par value
      $.001 per share (“Shares”), of Middle Kingdom Alliance Corp., a Delaware
      corporation (the “Company”) for each Warrant evidenced by this Class A Warrant
      Certificate. The Warrant entitles the holder thereof to purchase from the
      Company, commencing on the later of (i) the consummation by the Company of
      a
      merger, capital stock exchange, asset acquisition or other similar business
      combination or (ii) __________, 2007, such number of Shares of the Company
      at
      the price of $5.00 per share, upon surrender of this Class A Warrant Certificate
      and payment of the Warrant Price at the office or agency of the Warrant Agent,
      Continental Stock Transfer & Trust Company (such payment to be made by check
      made payable to the Warrant Agent), but only subject to the conditions set
      forth
      herein and in the Warrant Agreement between the Company and Continental Stock
      Transfer & Trust Company. The
      Company shall not be obligated to deliver any securities pursuant to the
      exercise of a Warrant and shall have no obligation to settle a Warrant exercise
      unless a registration statement under the Securities Act of 1933, as amended,
      (the “Act”) with respect to the Common Stock is effective, subject to the
      Company satisfying its obligations under Section 6.4 of the Class A Warrant
      Agreement to use its best efforts. In the event that a registration statement
      with respect to the Common Stock underlying a Warrant is not effective under
      the
      Act, the holder of such Warrant shall not be entitled to exercise such Warrant
      and such Warrant may have no value and expire worthless. In no event will the
      Company be required to net cash settle the warrant exercise. The Warrant
      Agreement provides that upon the occurrence of certain events the Warrant Price
      and the number of Warrant Shares purchasable hereunder, set forth on the face
      hereof, may, subject to certain conditions, be adjusted. The term Warrant Price
      as used in this Class A Warrant Certificate refers to the price per Share at
      which Shares may be purchased at the time the Warrant is exercised.

    

    No
      fraction of a Share will be issued upon any exercise of a Warrant. If the holder
      of a Warrant would be entitled to receive a fraction of a Share upon any
      exercise of a Warrant, the Company shall, upon such exercise, round up to the
      nearest whole number the number of Shares to be issued to such holder.

    

    Upon
      any
      exercise of the Warrant for less than the total number of full Shares provided
      for herein, there shall be issued to the registered holder hereof or his
      assignee a new Class A Warrant Certificate covering the number of Shares for
      which the Warrant has not been exercised. 

    

    Class
      A
      Warrant Certificates, when surrendered at the office or agency of the Warrant
      Agent by the registered holder hereof in person or by attorney duly authorized
      in writing, may be exchanged in the manner and subject to the limitations
      provided in the Warrant Agreement, but without payment of any service charge,
      for another Class A Warrant Certificate or Class A Warrant Certificates of
      like
      tenor and evidencing in the aggregate a like number of Warrants.

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    

    Upon
      due
      presentment for registration of transfer of the Class A Warrant Certificate
      at
      the office or agency of the Warrant Agent, a new Class A Warrant Certificate
      or
      Class A Warrant Certificates of like tenor and evidencing in the aggregate
      a
      like number of Warrants shall be issued to the transferee in exchange for this
      Class A Warrant Certificate, subject to the limitations provided in the Warrant
      Agreement, without charge except for any applicable tax or other governmental
      charge.

    

    The
      Company and the Warrant Agent may deem and treat the registered holder as the
      absolute owner of this Class A Warrant Certificate (notwithstanding any notation
      of ownership or other writing hereon made by anyone), for the purpose of any
      exercise hereof, of any distribution to the registered holder, and for all
      other
      purposes, and neither the Company nor the Warrant Agent shall be affected by
      any
      notice to the contrary.

    

    This
      Warrant does not entitle the registered holder to any of the rights of a
      Stockholder of the Company until exercised.

      WARRANT

    

      THIS
        CERTIFIES THAT, for value received ____________is the registered holder of
        a
        Class B Warrant or Class B Warrants expiring ________, 2013 (the “Warrant”) to
        purchase one fully paid and non-assessable share of common stock, par value
        $.001 per share (the “Common Stock”), of Middle Kingdom Alliance Corp., a
        Delaware corporation (the “Company”) for each Warrant evidenced by this Class B
        Warrant Certificate. The Warrant entitles the holder thereof to purchase
        from
        the Company, commencing on the later of (i) the consummation by the Company
        of a
        merger, capital stock exchange, asset acquisition or other similar business
        combination or (ii) __________, 2007, such number of shares of Common Stock
        of
        the Company at the price of $5.00 per share, upon surrender of this Class
        B
        Warrant Certificate and payment of the Warrant Price at the office or agency
        of
        the Warrant Agent, Continental Stock Transfer & Trust Company (such payment
        to be made by check made payable to the Warrant Agent), but only subject
        to the
        conditions set forth herein and in the Warrant Agreement between the Company
        and
        Continental Stock Transfer & Trust Company. The
        Company shall not be obligated to deliver any securities pursuant to the
        exercise of a Warrant and shall have no obligation to settle a Warrant exercise
        unless a registration statement under the Securities Act of 1933, as amended,
        (the “Act”) with respect to the Common Stock is effective, subject to the
        Company satisfying its obligations under Section 7.4 of the Class B Warrant
        Agreement to use its best efforts. In the event that a registration statement
        with respect to the Common Stock underlying a Warrant is not effective under
        the
        Act, the holder of such Warrant shall not be entitled to exercise such Warrant
        and such Warrant may have no value and expire worthless. In no event will
        the
        Company be required to net cash settle the warrant exercise. The Warrant
        Agreement provides that upon the occurrence of certain events the Warrant
        Price
        and the number of Warrant Shares purchasable hereunder, set forth on the
        face
        hereof, may, subject to certain conditions, be adjusted. The term Warrant
        Price
        as used in this Class B Warrant Certificate refers to the price per share
        at
        which Common Stock may be purchased at the time the Warrant is exercised.
        

    

    No
      fraction of a share of Common Stock will be issued upon any exercise of a
      Warrant. If the holder of a Warrant would be entitled to receive a fraction
      of a
      share of Common Stock upon any exercise of a Warrant, the Company shall, upon
      such exercise, round up to the nearest whole number the number of shares of
      Common Stock to be issued to such holder. 

    

    Upon
      any
      exercise of the Warrant for less than the total number of full shares of Common
      Stock provided for herein, there shall be issued to the registered holder hereof
      or his assignee a new Class B Warrant Certificate covering the number of shares
      of Common Stock for which the Warrant has not been exercised. 

    

    Class
      B
      Warrant Certificates, when surrendered at the office or agency of the Warrant
      Agent by the registered holder hereof in person or by attorney duly authorized
      in writing, may be exchanged in the manner and subject to the limitations
      provided in the Warrant Agreement, but without payment of any service charge,
      for another Class B Warrant Certificate or Class B Warrant Certificates of
      like
      tenor and evidencing in the aggregate a like number of Warrants.

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    

    Upon
      due
      presentment for registration of transfer of the Class B Warrant Certificate
      at
      the office or agency of the Warrant Agent, a new Class B Warrant Certificate
      or
      Class B Warrant Certificates of like tenor and evidencing in the aggregate
      a
      like number of Warrants shall be issued to the transferee in exchange for this
      Class B Warrant Certificate, subject to the limitations provided in the Warrant
      Agreement, without charge except for any applicable tax or other governmental
      charge.

    

    The
      Company and the Warrant Agent may deem and treat the registered holder as the
      absolute owner of this Class B Warrant Certificate (notwithstanding any notation
      of ownership or other writing hereon made by anyone), for the purpose of any
      exercise hereof, of any distribution to the registered holder, and for all
      other
      purposes, and neither the Company nor the Warrant Agent shall be affected by
      any
      notice to the contrary.

    

    This
      Warrant does not entitle the registered holder to any of the rights of a
      Stockholder of the Company until exercised.

    

    The
      Company reserves the right to call the Warrant, at any time prior to its
      exercise, with a notice of call in writing to the Warrant holders of record,
      giving 30 days' notice of such call at any time after the Warrant becomes
      exercisable if the last sale price of the Common Stock has been at least $16.00
      per share on each of 20 trading days within any 30 trading day period ending
      on
      the third business day prior to the date on which notice of such call is given.
      The call price of the Warrants is to be $.01 per Warrant. Any Warrant either
      not
      exercised, or tendered back to the Company by the end of the date specified
      in
      the notice of call, shall be canceled on the books of the Company and have
      no
      further value except for the $.01 call price.
