Collateral Agreement by execution and delivery of an instrument in the form of this Supplement. The undersigned Subsidiary (the “New Subsidiary”) is executing this Supplement in accordance with the requirements of the Credit
Agreement to become a Subsidiary Party under the Guarantee and Collateral Agreement in order to induce the Lenders to make additional Loans and each Issuing Bank to issue additional Letters of Credit and as consideration for Loans previously made
and Letters of Credit previously issued. 
 Accordingly, the Collateral Agent and the New Subsidiary agree as follows: 
 SECTION 1. In accordance with Section 7.15 of the Guarantee and Collateral Agreement, the New Subsidiary by its signature below becomes a Subsidiary









 
Party and a Guarantor under the Guarantee and Collateral Agreement with the same force and effect as if originally named therein as a Subsidiary Party and a
Guarantor, and the New Subsidiary hereby (a) agrees to all the terms and provisions of the Guarantee and Collateral Agreement applicable to it as a Subsidiary Party and Guarantor thereunder and (b) represents and warrants that the
representations and warranties made by it as a Guarantor thereunder are true and correct, in all material respects, on and as of the date hereof. In furtherance of the foregoing, the New Subsidiary, as security for the payment and performance in
full of the Obligations (as defined in the Guarantee and Collateral Agreement), does hereby create and grant to the Collateral Agent, its successors and assigns, for the ratable benefit of the Secured Parties, their successors and assigns, a
security interest in and Lien on all the New Subsidiary’s right, title and interest in and to the Collateral (as defined in the Guarantee and Collateral Agreement) of the New Subsidiary. Each reference to a “Subsidiary Party” or a
“Guarantor” in the Guarantee and Collateral Agreement shall be deemed to include the New Subsidiary. The Guarantee and Collateral Agreement is hereby incorporated herein by reference. 
 SECTION 2. The New Subsidiary represents and warrants to the Collateral Agent and the other Secured Parties that this Supplement has been duly
authorized, executed and delivered by it and constitutes its legal, valid and binding obligation, enforceable against it in accordance with its terms, subject to (i) the effects of bankruptcy, insolvency, moratorium, reorganization, fraudulent
conveyance or other similar laws affecting creditors’ rights generally, (ii) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law) and (iii) implied covenants of
good faith and fair dealing. 
 SECTION 3. This Agreement may be executed in two or more counterparts, each of which shall constitute an
original but all of which when taken together shall constitute but one contract. This Supplement shall become effective when (a) the Collateral Agent shall have received a counterpart of this Supplement that bears the signature of the New
Subsidiary and (b) the Collateral Agent has executed a counterpart hereof. 
 SECTION 4. The New Subsidiary hereby represents and
warrants that (a) set forth on Schedule I attached hereto is a true and correct schedule of the location of any and all Article 9 Collateral of the New Subsidiary, (b) set forth on Schedule II attached hereto is a
true and correct schedule of all the Pledged Securities of the New Subsidiary and (c) set forth under its signature hereto, is the true and correct legal name of the New Subsidiary, its jurisdiction of formation and the location of its chief

 SECTION 5. Except as expressly supplemented hereby, the Guarantee and Collateral Agreement shall remain in full force
and effect. 
 SECTION 6. THIS SUPPLEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS SUPPLEMENT SHALL BE CONSTRUED IN
ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK. 







 SECTION 7. In the event any one or more of the provisions contained in this Supplement should be held
invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein and in the Guarantee and Collateral Agreement shall not in any way be affected or impaired thereby. The parties
shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

 SECTION 8. All communications and notices hereunder shall be in writing and given as provided in Section 7.01 of the Guarantee and
Collateral Agreement. 
 SECTION 9. The New Subsidiary agrees to reimburse the Collateral Agent for its reasonable out-of-pocket expenses in
connection with this Supplement, including the reasonable fees, disbursements and other charges of counsel for the Collateral Agent.
