      generality of the foregoing, the Trustee shall not be responsible in any manner whatsoever for or with respect to any of the recitals or statements contained herein, all of which recitals or statements are made solely by the Company, and the Trustee
      makes no representation with respect to any such matters.  Additionally, the Trustee makes no representation or warranty as to the validity or sufficiency of this Third Supplemental Indenture.  For the avoidance of doubt, the Trustee, by executing

      the law of the State of New York (without regard to the conflicts of laws principles thereof).

     

      

    SECTION 306.     Counterparts.

     

    

    This Third 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 Third 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.

    SECTION 308.     Conflicts.

     

    

    To the extent of any inconsistency between the terms of the Indenture and this Third Supplemental Indenture, the terms of this Third 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.

     

    

    This Third Supplemental Indenture, together with the Indenture, constitutes the entire agreement of the parties hereto with respect to the amendments to the Indenture set forth herein.

     

      

    SECTION 310.     Execution.

     

    

    Notwithstanding anything in the Indenture to the contrary, the words “execution,” “signed,” “signature,” “delivery,” and words of like import in or relating to this Third Supplemental
      Indenture or any document to be signed in connection herewith, including by the Trustee, shall be deemed to include electronic signatures, deliveries or the keeping of records in electronic form, each of which shall be of the same legal effect,
      validity or enforceability as a manually executed signature, physical delivery thereof or the use of a paper-based recordkeeping system, as the case may be, and the parties hereto consent to conduct the transactions contemplated hereunder by
      electronic means.
