    WHEREAS,
      the Issuers have heretofore executed and delivered to the Trustee an indenture,
      dated as of May 18, 2004 (as supplemented by the First Supplemental Indenture
      thereto, dated as of February 1, 2005, the Second Supplemental Indenture
      thereto, dated as of March 30, 2005, the Third Supplemental Indenture thereto,
      dated as of October 26, 2005, the Fourth Supplemental Indenture thereto,
      dated as of January 3, 2006, and the Fifth Supplemental Indenture thereto,
      dated as of May 1, 2006, the “Indenture”),
      providing for the issuance of 10% Senior Notes due 2012 (the “Notes”);

    


    WHEREAS,
      the Indenture provides that under certain circumstances the Guaranteeing
Subsidiaries
      shall
      execute and deliver to the Trustee a supplemental indenture pursuant to which
      each Guaranteeing Subsidiary shall unconditionally guarantee all of the Issuers’
Obligations under the Notes and the Indenture on the terms and conditions set
      forth herein (the “Note
      Guarantee”);
      and

    


    WHEREAS,
      pursuant to Section 9.01 of the Indenture, the Trustee is authorized to execute
      and deliver this Supplemental Indenture.

    


    NOW,
      THEREFORE, in consideration of the foregoing and for other good and valuable
      consideration, the receipt of which is hereby acknowledged, each of the
      Guaranteeing Subsidiaries and the Trustee mutually covenant and agree for the
      equal and ratable benefit of the Holders of the Notes as follows:

    


    1.    CAPITALIZED
      TERMS.
      Capitalized terms used herein without definition shall have the meanings
      assigned to them in the Indenture.

    


    2.    AGREEMENT
      TO GUARANTEE.
      Each
      Guaranteeing Subsidiary hereby agrees to provide an unconditional Guarantee
      on
      the terms and subject to the conditions set forth in the Note Guarantee and
      in
      the Indenture including but not limited to Article 10 thereof.

    


    4.    NO
      RECOURSE AGAINST OTHERS.
      No
      past, present or future director, manager, officer, employee, incorporator,
      member, stockholder or agent of a Guaranteeing Subsidiary, as such, shall have
      any liability for any obligations of the Issuers or such Guaranteeing Subsidiary
      under the Notes, any Note Guarantees, the Indenture or this Supplemental
      Indenture or for any claim based on, in respect of, or by reason of, such
      obligations or their creation. Each Holder of the Notes by accepting a Note
      waives and releases all such liability. The waiver and release are part of
      the
      consideration for issuance of the Notes. Such waiver may not be effective to
      waive liabilities under the federal securities laws and it is the view of the
      SEC that such a waiver is against public policy.


    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    


    5.    NEW
      YORK
      LAW TO GOVERN. THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE
      USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE WITHOUT GIVING EFFECT TO APPLICABLE
      PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS
      OF
      ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

    


    6.    COUNTERPARTS.
      The
      parties may sign any number of copies of this Supplemental Indenture. Each
      signed copy shall be an original, but all of them together represent the same
      agreement.

    


    7.    EFFECT
      OF
      HEADINGS.
      The
      Section headings herein are for convenience only and shall not affect the
      construction hereof.

    


    8.    THE
      TRUSTEE.
      The
      Trustee shall not be responsible in any manner whatsoever for or in respect
      of
      the validity or sufficiency of this Supplemental Indenture or for or in respect
      of the recitals contained herein, all of which recitals are made solely by
      the
      Guaranteeing Subsidiaries and the Issuers.
