 NOW THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the New
Guarantor and the Trustee mutually covenant and agree for the equal and ratable benefit of the holders of the Notes as follows: 
 1.
Defined Terms. As used in this Supplemental Indenture, terms defined in the Indenture or in the preamble or recital hereto are used herein as therein defined, except that the term “Holders” in this Supplemental Indenture
shall refer to the term “Holders” as defined in the Indenture and the Trustee acting on behalf of and for the benefit of such Holders. The words “herein,” “hereof” and “hereby” and other words of
similar import used in this Supplemental Indenture refer to this Supplemental Indenture as a whole and not to any particular section hereof. 
 2. Agreement to Guarantee. The New Guarantor hereby agrees, jointly and severally with all existing Guarantors, to unconditionally guarantee the Issuer’s obligations under the Indenture and the Notes on the terms and subject to
the conditions set forth in the Guarantee and the Indenture, including but not limited to Article 12 of the Indenture, and to be bound by all other applicable provisions of the Indenture and the Notes applying to a Guarantor and to perform all
of the obligations and agreements of a Guarantor under the Indenture. 







 3. Notices. All notices or other communications to the New Guarantor shall be given as provided in
Section 106 of the Indenture. 
 4. Ratification of Indenture; Supplemental Indentures Part of Indenture. Except as expressly
amended hereby, the Indenture is in all respects ratified and confirmed and all the terms, conditions and provisions thereof shall remain in full force and effect. This Supplemental Indenture shall form a part of the Indenture for all purposes, and
every holder of Notes heretofore or hereafter authenticated and delivered shall be bound hereby. 
 5. Waiver of Claims. The New
Guarantor waives and shall not in any manner whatsoever claim or take the benefit or advantage of any rights of reimbursement, indemnity or subrogation or any other rights against the Issuer or any other Guarantor as a result of any payment by such
Guarantor under its Guarantee; 
 6. No Recourse Against Others. No past, present or future director, officer, employee, incorporator,
stockholder or agent of the New Guarantor, as such, shall have any liability for any obligations of the Company or any existing Guarantor under the Notes, any 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. 
 7. Governing Law. THIS SUPPLEMENTAL INDENTURE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. 
 8. The Trustee. The Trustee makes no representation as to the validity or sufficiency of this Supplemental Indenture. The recitals and statements herein are deemed to be those of the Issuer, the Guarantors and
the New Guarantor and not of the Trustee. Each signed copy shall be an original, but all of them together represent the same agreement. 
 9.
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. 
 10. Effect of Headings. The Section headings herein are for convenience only and shall not effect the construction thereof.
