    [INVESTOR
      NAMES]


    


    Dear
      Investors:

    


    Reference
      is made to that certain Amended and Restated Confidential Private Placement
      Memorandum, dated June 7, 2007, in connection with the reverse merger of
      Hemcure, Inc., a publicly traded Nevada corporation (“HMCU”),
      and
      AuraSound, Inc., a California corporation (“AuraSound”)
      (the
“PPM”).
      Capitalized terms used but not defined herein shall have the meanings ascribed
      to them in the PPM.

    


    As
      an
      inducement to the investors who purchase Securities pursuant to the PPM, the
      undersigned hereby agrees that from the date hereof and continuing until the
      24
      month anniversary of the effectiveness date of the Initial Registration
      Statement (the “Lock-Up
      Period”),
      the
      undersigned will not (A) offer, sell, contract to sell, pledge, hypothecate,
      transfer or otherwise dispose of, directly or indirectly, any shares of capital
      stock or other equity securities of HMCU (including without limitation any
      shares of capital stock or other equity securities issued or issuable to the
      undersigned as the result of any stock split, stock dividend or distribution
      on
      such securities) and any options, warrants or other rights to purchase or
      acquire shares of capital stock of HMCU, in each case whether now owned or
      hereafter acquired (the “Lock-Up
      Shares”),
      (B)
      enter into any agreement or transaction that would have the same effect, (C)
      enter into any swap, hedge or other arrangement that transfers, in whole or
      in
      part, any of the economic consequences of ownership of the Lock-Up Shares,
      whether any such aforementioned transaction is to be settled by delivery of
      the
      Lock-Up Shares, in cash or otherwise, or (D) publicly disclose the intention
      to
      make any such offer, sale, pledge or disposition, without, in each case, the
      prior written consent of investors who purchased at least 60% of the Units
      issued under the PPM. 

    


    Notwithstanding
      the foregoing, the undersigned may transfer Lock-Up shares (i) as a bona
      fide
      gift or
      gifts, provided that the donee or donees thereof agree to be bound by the
      restrictions set forth herein, (ii) to any trust for the direct or indirect
      benefit of the undersigned or the immediate family of the undersigned, provided
      that the trustee of the trust agrees to be bound by the restrictions set forth
      herein, and provided further that any such transfer shall not involve a
      disposition for value, or (iii) in transactions relating to shares of common
      stock of HMCU acquired by the undersigned in open market transactions after
      the
      completion of the transactions contemplated by the PPM. For purposes of this
      Agreement, “immediate family” shall mean any relationship by blood, marriage or
      adoption, not more remote than first cousin.

     

    In
      furtherance of the foregoing, HMCU shall, and shall cause its transfer agent
      and
      registrar to, decline to make any transfer of the Lock-Up Shares if such
      transfer would constitute a violation or breach of this letter
      agreement.

    


    Each
      of
      the signatories hereto and AuraSound acknowledges that each of the investors
      who
      purchased Securities pursuant to the PPM are third party beneficiaries of this
      agreement and this agreement may not be modified or changed without the prior
      written consent of the investors who purchased at least sixty (60) percent
      of
      the Units under the PPM.

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

     

    This
      letter agreement shall be binding on the undersigned and the successors, heirs,
      personal representatives and assigns of the undersigned. This letter agreement
      or the rights hereunder may not be assigned by the investors named above, except
      to their respective partners and affiliates to which they transfer all or any
      portion of the Securities in accordance with applicable law or regulation.
