 WHEREAS, Section 4.15 of the

WHEREAS, pursuant to Section 9.01 of the Base Indenture, the Trustee, the Successor Issuers, the Original Issuers, the New Guarantors and

 NOW, THEREFORE, in consideration of the
foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Successor Issuers, the Original Issuers, the New Guarantors, the other Guarantors and the Trustee mutually covenant and agree for the equal and
ratable benefit of the Holders as follows: 
 1. CAPITALIZED TERMS. Capitalized terms used herein without definition shall have the meanings
assigned to them in the Indenture. 
 2. AGREEMENT TO ASSUME OBLIGATIONS. The Successor Issuers hereby unconditionally assume all
obligations of the Original Issuers, on the terms and subject to the conditions set forth in Article 5 of the Base Indenture, and agree to be bound by all other applicable provisions of the Indenture and the Notes and to perform all of the
obligations and agreements of an “Issuer” or “Co-Issuer”, as applicable, under the Indenture. 
 3. AGREEMENT TO

 2 







 
Successor Issuers or the Guarantors under the Notes, this Indenture, the Note Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder
by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. The waiver may not be effective to waive liabilities under the federal securities laws.

Section 12.02 of the Base Indenture. 
 6. RATIFICATION OF INDENTURE, SUPPLEMENTAL INDENTURES PART OF INDENTURE. Except as expressly

 7. GOVERNING LAW. THIS SUPPLEMENTAL
INDENTURE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. 
 8. 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 copies of this Supplemental Indenture and of signature pages by facsimile of 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 Base Indenture for all purposes. Signatures of the parties hereto transmitted by facsimile or PDF

 9. EFFECT OF HEADINGS. The Section headings of this Supplemental
Indenture have been inserted for convenience of reference only and are not to be considered part of this Supplemental Indenture or the Base Indenture and will in no way modify or restrict any of the terms or provisions hereof or thereof.

 11. TRUSTEE MAKES
