          discretion determine that the Securities of any series issued in the form of one or more Global Securities shall, in whole or in part, no longer be represented by such Global Security or Securities. In such event, the Company will execute, and

      The Company may consolidate with or merge with or into any other Person, provided that in any such
        case, either the Company shall be the continuing Person, or the successor Person shall expressly assume the due and punctual payment of the principal of and interest on all the Securities, according to their tenor, and the due and punctual
        performance and observance of all of the covenants and conditions of this Indenture to be performed by the Company by supplemental indenture satisfactory to the Trustee, executed and delivered to the Trustee by such Person.”

      In case of any such consolidation or merger and upon any such assumption by the successor Person, such successor Person shall succeed to and be
        substituted for the Company, with the same effect as if it has been named herein as the Company, and the predecessor Person shall be relieved of any obligation under this Indenture and the Securities. Such successor Person thereupon may cause to be
        signed, and may issue either in its own name or in the name of the Company, any or all of the Securities issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such
        successor Person, instead of the Company, and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver any Securities which previously shall have been signed and delivered
        by the officers of the Company to the Trustee for authentication, and any Securities which such successor Person thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Securities so issued shall in all respects
        have the same legal rank and benefit under this Indenture as the Securities theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such Securities had been issued at the date of the execution hereof.

       

      

      In case of any such consolidation or merger such changes in phraseology and form (but not in substance) may be made in the Securities
        thereafter issued as may be appropriate.”

      (A) the resulting, surviving or transferee Person (if not a Guarantor or the Company) shall expressly assume all the obligations of such Guarantor
        under each of its Guarantees hereunder; and

       

      

      (B) the Company delivers to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such consolidation or merger, and,
        if applicable, the assumption by the resulting or surviving Person of such Guarantor’s obligations under each of its Guarantees hereunder, complies with the Indenture.

       

      

      If the conditions set forth in (A) and (B) above are otherwise satisfied, the consolidation or merger of any Guarantor with or into any Person
        shall not be or be deemed to be a violation, default or breach by the Company or any Guarantor of any of the provisions of Article XV hereof.

       

      

      In the event that a Guarantor is disposed of in its entirety (whether by merger, consolidation or sale of its capital stock), such Guarantor shall
        be released from its obligations under each of its Guarantees.”

        officer of the Company and by the Treasurer or the Secretary or any Assistant Treasurer or any Assistant Secretary the Company, stating that in the course of the performance by the signers of their duties as officers of the Company and based upon a
        review made under their supervision of the activities of the Company during such year and of the Company’s performance under this Indenture they would normally obtain knowledge whether or not the Company is in default in the performance of any
        covenant or agreement contained herein, stating whether or not they have obtained knowledge that the Company is in default in the performance of any such covenant or agreement, and if so, specifying each such default of which the signers have
        knowledge and the nature thereof. For purposes of this Section, such compliance shall be determined without regard to any period of grace or requirement of notice provided under this Indenture.”

      4

      
        

    

    (3) Subject to Clause (2) above and to such applicable provisions, if any, as may be specified as contemplated by Section 301, any exchange of a Global Security for other Securities may be made in whole or in part, and
      all Securities issued in exchange for a Global Security or any portion thereof shall be registered in such names as the Depositary for such Global Security shall direct.

    

    

    (4) Every Security authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Security or any portion thereof, whether pursuant to this Section, Section 304, 306, 906 or 1107
      or otherwise, shall be authenticated and delivered in the form of, and shall be, a Global Security, unless such Security is registered in the name of a Person other than the Depositary for such Global Security or a nominee thereof.”

      executed and delivered to the Trustee, in form satisfactory to the Trustee, the due and punctual payment of the principal of and any premium and interest on all the Securities and the performance or observance of every covenant of this Indenture on
      the part of the Company to be performed or observed and, for each Security that by its terms provides for conversion, shall have provided for the right to convert such Security in accordance with its terms; and

    SECTION 303.          Provisions Binding on Successors.

    

    

    All of the covenants, stipulations, promises and agreements made in this Supplemental Indenture by each of the parties hereto shall bind its successors and assigns whether so expressed or not.

    SECTION 306.          Counterparts.

    

    

    This Supplemental Indenture may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same
      instrument.  This Supplemental Indenture shall become effective and constitute a binding agreement between the parties hereto when counterparts hereof shall have been executed and delivered by each of the parties hereto.

    

    

    SECTION 307.          Separability Clause.

    

    

    In case any provision in this Supplemental Indenture shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

    

    

    SECTION 308.          Conflicts.

    

    

    To the extent of any inconsistency between the terms of the Indenture and this Supplemental Indenture, the terms of this Supplemental Indenture will control.  If any provision hereof limits, qualifies or conflicts with
      another provision hereof or of the Indenture which is required to be included in the Indenture by any of the provisions of the Trust Indenture Act, such required provisions shall control.

    

    

    SECTION 309.          Entire Agreement.
