WHEREAS, Section 9.2 of the Senior Indenture provides that the Senior Indenture may be amended by the Company and the Trustee with the

terms, subject to customary exceptions. 
 WHEREAS pursuant to Section 9.2 of the Senior Indenture, the Company desires to execute and
deliver this Supplemental Indenture, and has requested and hereby directs that the Trustee join with it in the execution and delivery of this Supplemental Indenture; and

ARTICLE 1 
 AMENDMENTS 

Section 1.01.    Amendments to the Indenture and Notes. 

(a)    The reference to “upon not less than 30 nor more than 60 days’ notice” in the first sentence of the
first paragraph of Section 3.2 of the Senior Indenture is hereby deleted and replaced with the following: “upon not less than three Business Days’ notice.” 

ARTICLE 2 
 MISCELLANEOUS 

Section 2.01.    Effect of Supplemental Indenture. From and after the Amendment Operative Date (as defined
below), the Indenture shall be amended and supplemented with respect to the Notes in accordance herewith, and this Supplemental Indenture shall form a part of the Indenture for all purposes, and every Holder of Notes heretofore or hereafter
authenticated and delivered under the Indenture shall be bound thereby. 
 Section 2.02.    Indenture Remains in
Full Force and Effect. Except as amended and supplemented by this Supplemental Indenture, all provisions in the Indenture shall remain in full force and effect.

 Section 2.03.    References to Supplemental Indenture. Any and
all notices, requests, certificates and other instruments executed and delivered after the Amendment Operative Date may refer to the Indenture without making specific reference to this Supplemental Indenture, but nevertheless all such references
shall include this Supplemental Indenture unless the context requires otherwise. 
 Section 2.04.    Conflict
with Trust Indenture Act. If any provision of this Supplemental Indenture limits, qualifies or conflicts with any provision of the Trust Indenture Act of 1939 (the “TIA”) that is required under the TIA to be part of and govern
any provision of this Supplemental Indenture, the provision of the TIA shall control. If any provision of this Supplemental Indenture modifies or excludes any provision of the TIA that may be so modified or excluded, the provision of the TIA shall
be deemed to apply to the Indenture as so modified or to be excluded by this Supplemental Indenture, as the case may be. 

Section 2.05.    Separability. In case any provision in this Supplemental Indenture is invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining provisions will not in any way be affected or impaired thereby. 

Section 2.06.    Terms Defined in the Indenture. All capitalized terms not otherwise defined herein shall have
the meanings ascribed to them in the Indenture. 
 Section 2.07.    Headings. The headings of the Articles
and Sections of this Supplemental Indenture have been inserted for convenience of reference only, are not to be considered a part of the Indenture and in no way modify or restrict any of the terms and provisions of this Supplemental Indenture. 

Section 2.08.    Benefits of Supplemental Indenture. Nothing in this Supplemental Indenture or the Notes,
express or implied, shall give to any Person, other than the parties hereto and thereto and their successors hereunder and thereunder and the holders of the Notes any benefit of any legal or equitable right, remedy or claim under the Indenture, this
Supplemental Indenture or the Notes. 
 Section 2.09.    Successors. All agreements of the Company in this
Supplemental Indenture will bind its successors. All agreements of the Trustee in this Supplemental Indenture will bind its successors. 

Section 2.10.    Duplicate Originals. 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. The exchange of copies of this Supplemental Indenture and of signature pages by facsimile or PDF transmission shall constitute effective
execution and delivery of this Supplemental Indenture as to the parties hereto and may be used in lieu of the original Supplemental Indenture for all purposes. Signatures of the parties hereto transmitted by facsimile or PDF shall be deemed to be
their original signatures for all purposes.

 Section 2.11.    Effectiveness. This Supplemental Indenture shall
become a binding agreement between the parties hereto when executed by the parties hereto. As used herein, the “Amendment Operative Date”, which is the date that the Proposed Amendments shall be operative, shall mean the date and
time that the Company accepts the validly tendered Notes for purchase pursuant to, and subject to the conditions set forth in, the Offer to Purchase. If, after the date hereof, either the Offer to Purchase is terminated or withdrawn or all payments
in respect of the Notes accepted for payment pursuant to the Offer to Purchase are not made as required by the Offer to Purchase, the Proposed Amendments shall have no effect and the Indenture shall be deemed to be amended so that it reads the same
as it did immediately prior to the date hereof. The Company shall provide prompt written notice to the Trustee if it accepts the Notes for purchase and remits payment pursuant to the Offer to Purchase, or if the Offer to Purchase is terminated or
withdrawn or all payments in respect of the Notes accepted for payment pursuant to the Offer to Purchase are not made. The Company shall cause Notes that have been purchased to be promptly delivered to the Trustee for cancellation pursuant to
Section 2.11 of the Senior Indenture, and the Trustee is hereby authorized and directed to cancel such Notes upon receipt. 

Section 2.12.    Further Instruments and Acts. Upon request of the Company, the Trustee will execute and
deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purpose of this Supplemental Indenture. 

Section 2.13.    Acceptance. The Trustee accepts the amendments of the Indenture effected by this Supplemental
Indenture, but on the terms and conditions set forth in the Indenture, including the terms and provisions defining and limiting the liabilities and responsibilities of the Trustee. Without limiting the generality of the foregoing, the Trustee makes
no representation or warranty as to the validity or sufficiency of this Supplemental Indenture or as to the accuracy of the recitals to this Supplemental Indenture.
