W I T N E S S E T H


 


WHEREAS, the Company
has heretofore executed and delivered to the Trustee an indenture (the “Indenture”), dated as of December 11,
2019 providing for the issuance of 4.750% Senior Notes due 2028 (the “Notes”);


 


WHEREAS, the Indenture
provides that under certain circumstances the Guaranteeing Subsidiaries shall execute and deliver to the Trustee a supplemental
indenture pursuant to which each Guaranteeing Subsidiary shall fully and unconditionally guarantee all of the Company’s Obligations
under the Notes and the Indenture on the terms and conditions set forth herein (the “Subsidiary Guarantee”);
and


 


WHEREAS, pursuant to
Sections 4.10 and 9.01 of the Indenture, the Trustee, the Company and the other Guarantors are 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, the Guaranteeing Subsidiaries
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 becomes a party to the Indenture as a Guarantor and as
such will have all the rights and be subject to all the Obligations and agreements of Guarantors under the Indenture. Each Guaranteeing
Subsidiary hereby agrees to provide a full and unconditional Guarantee on the terms and subject to the conditions set forth in
the Subsidiary Guarantee and in the Indenture including but not limited to Article 10 thereof.


 


3.                  NO
RECOURSE AGAINST OTHERS. No director, officer, employee, incorporator or stockholder of the Company or any Guarantor, as
such, will have any liability for any obligations of the Company or the Guarantors under the Notes, this Indenture, the
Subsidiary Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each
Holder of 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. The waiver may not be effective to waive liabilities under the federal securities
laws.


 






     


     


    

 


4.                 
NEW YORK LAW TO GOVERN. THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL
INDENTURE WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF
ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.


 


5.                 
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.


 


6.                 
EFFECT OF HEADINGS. The Section headings herein are for convenience only and shall not affect the construction hereof.


 


7.                 
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
the Guaranteeing Subsidiaries and the Company.


 


8.                
RATIFICATION OF INDENTURE; SUPPLEMENTAL INDENTURE FOR ADDITIONAL GUARANTEES 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 for Additional Guarantees shall form a part of the Indenture for all
purposes, and every Holder of Notes heretofore or hereafter authenticated and delivered shall by bound hereby.


 


9.                 ELECTRONIC
SIGNATURES. Each of the transaction parties agrees on behalf of itself, and any Person acting or claiming by, under or
through such transaction party, that any written instrument delivered in connection with this Supplemental Indenture, the
Indenture or any related document, including without limitation any amendments or supplements to such documents, may be
executed by electronic methods (whether by .pdf scan or utilization of an electronic signature platform or application). Any
electronic signature document delivered via email from a person authorized on an incumbency certificate provided by the
Company, any Guaranteeing Subsidiary or any other Guarantor to the Trustee shall be considered signed or executed by such
person on behalf of the Company, such Guaranteeing Subsidiary, or such other Guarantor, as applicable. Each of the Company,
the Guaranteeing Subsidiaries, and the other Guarantors agree to assume all risks arising out of the use of electronic
methods for all purposes including the authorization, execution, delivery, or submission of documents,
instruments, notices, directions, instructions, reports, opinions and certificates to the Trustee, including
without limitation the risk of the Trustee acting on unauthorized instructions, and the risk of interception and misuse by
third parties. Any electronic signature shall have the same legal validity and enforceability as a manually executed
signature to the fullest extent permitted by applicable law, including the Federal Electronic Signatures in Global and
National Commerce Act, the New York State Electronic Signatures and Records Act, or any similar federal or state law, rule or
regulation, as the same may be in effect from time to time, and the parties hereby waive any objection to the contrary. Any
document accepted, executed or agreed to in conformity with such laws will be binding on all parties hereto to the same
extent as if it were physically executed and each party hereby consents to the use of any third party electronic signature
capture service providers as may be reasonably chosen by a signatory hereto.
