W I T N E S S E T H

WHEREAS, the Issuers and certain Subsidiaries of the Company have heretofore executed and delivered to the Trustee an indenture, dated as of February 22, 2017 (the “Original Indenture”), providing for the issuance by the Issuers of 6.125% Senior Notes due 2025 (the “Notes”);

WHEREAS, the Issuers and certain Subsidiaries of the Company have heretofore executed and delivered to the Trustee the First Supplemental Indenture, dated as of July 18, 2018 (the “First Supplemental Indenture”), pursuant to which certain Subsidiaries of the Company became Guarantors;

WHEREAS, the Issuers and certain Subsidiaries of the Company have heretofore executed and delivered to the Trustee the Second Supplemental Indenture, dated as of January 25, 2019 (the “Second Supplemental Indenture”), pursuant to which certain Subsidiaries of the Company became Guarantors;

WHEREAS, the Issuers and certain Subsidiaries of the Company have heretofore executed and delivered to the Trustee the Third Supplemental Indenture, dated as of October 31, 2019 (the “Third Supplemental Indenture”), pursuant to which certain Subsidiaries of the Company became Guarantors;

WHEREAS, the Original Indenture as amended and supplemented by the First Supplemental Indenture, the Second Supplemental Indenture and the Third Supplemental Indenture is referred to herein as the “Indenture”;

WHEREAS, the Indenture provides that under certain circumstances, each Guaranteeing Subsidiary shall execute and deliver to the Trustee a supplemental indenture pursuant to which such 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 Guaranteeing Subsidiary 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.

3.                                      EXECUTION AND DELIVERY.  Each Guaranteeing Subsidiary agrees that the Note Guarantees shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Note Guarantee.

4.                                      NO RECOURSE AGAINST OTHERS.  No past, present or future director, officer, partner, employee, incorporator, organizer, manager, unitholder or other owner of Capital Stock (as defined in the Indenture) of a Guaranteeing Subsidiary or agent thereof, as such, shall have any liability for any obligations of the Issuers, the Guarantors, or such Guaranteeing Subsidiary or any other Subsidiary of an Issuer providing a Note Guarantee 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 LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE.

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.  The exchange of signed copies of this Supplemental Indenture by facsimile transmission or emailed portable document format (pdf) shall constitute effective execution and delivery of this Supplemental Indenture as to the parties hereto and such copies may be used in lieu of the original Supplemental Indenture for all purposes.  Signatures of the parties hereto transmitted by facsimile or portable document format (pdf) shall be deemed to be their original signatures for all purposes other than authentication of Notes by the Trustee.

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 each Guaranteeing Subsidiary and the Issuers.
