NOW, THEREFORE, in consideration of the premises and mutual covenants herein contained and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, each Grantor hereby agrees as follows: 
 1. DEFINED TERMS. All initially
capitalized terms used but not otherwise defined herein have the meanings given to them in the Second Lien Guaranty and Security Agreement or, if not defined therein, in the Credit Agreement, and this Trademark Security Agreement shall be subject to
the rules of construction set forth in Section 1(b) of the Second Lien Guaranty and Security Agreement, which rules of construction are incorporated herein by this reference, mutatis mutandis. 

2. GRANT OF SECURITY INTEREST IN TRADEMARK COLLATERAL. Each Grantor hereby unconditionally grants, assigns, and pledges to Agent, for
the benefit each member of the Lender Group, to secure the Secured Obligations, a continuing security interest (referred to in this Trademark Security Agreement as the “Security Interest”) in all of such Grantor’s right, title
and interest in and to the following, whether now owned or hereafter acquired or arising (collectively, the “Trademark Collateral”): 

  
 1 








 (a) all of its Trademarks and Trademark Intellectual Property Licenses to which it is a party
including those referred to on Schedule I; 
 (b) all goodwill of the business connected with the use of, and symbolized by, each
Trademark and each Trademark Intellectual Property License; and 
 (c) all products and proceeds (as that term is defined in the Code) of the
foregoing, including any claim by such Grantor against third parties for past, present or future (i) infringement or dilution of any Trademark or any Trademarks exclusively licensed under any Intellectual Property License, including right to
receive any damages, (ii) injury to the goodwill associated with any Trademark, or (iii) right to receive license fees, royalties, and other compensation under any Trademark Intellectual Property License. 

3. SECURITY FOR SECURED OBLIGATIONS. This Trademark Security Agreement and the Security Interest created hereby secures the payment and
performance of the Secured Obligations, whether now existing or arising hereafter. Without limiting the generality of the foregoing, this Trademark Security Agreement secures the payment of all amounts which constitute part of the Secured
Obligations and would be owed by Grantors, or any of them, to Agent, the other members of the Lender Group or any of them, whether or not they are unenforceable or not allowable due to the existence of an Insolvency Proceeding involving any Grantor.

 4. SECURITY AGREEMENT. The Security Interest granted pursuant to this Trademark Security Agreement is granted in conjunction with
the security interests granted to Agent, for the benefit of the Lender Group, pursuant to the Second Lien Guaranty and Security Agreement. Each Grantor hereby acknowledges and affirms that the rights and remedies of Agent with respect to the
Security Interest in the Trademark Collateral made and granted hereby are more fully set forth in the Second Lien Guaranty and Security Agreement, the terms and provisions of which are incorporated by reference herein as if fully set forth herein.
To the extent there is any inconsistency between this Trademark Security Agreement and the Second Lien Guaranty and Security Agreement, the Second Lien Guaranty and Security Agreement shall control. 

5. AUTHORIZATION TO SUPPLEMENT. If any Grantor shall obtain rights to any new trademarks, the provisions of this Trademark Security
Agreement shall automatically apply thereto. Grantors shall give prompt notice in writing to Agent with respect to any such new trademarks or renewal or extension of any trademark registration. Without limiting Grantors’ obligations under this
Section, Grantors hereby authorize Agent unilaterally to modify this Trademark Security Agreement by amending Schedule I to include any such new trademark rights of each Grantor. Notwithstanding the foregoing, no failure to so modify this
Trademark Security Agreement or amend Schedule I shall in any way affect, invalidate or detract from Agent’s continuing security interest in all Collateral, whether or not listed on Schedule I.

Security Agreement may be executed in any number of counterparts and by different parties on separate counterparts, each of which, when executed and delivered, shall be deemed to be an original, and all of which, when taken together, shall
constitute but one and the same Trademark Security Agreement. Delivery of an executed counterpart of this Trademark Security Agreement by telefacsimile or other electronic method of transmission shall be equally as effective as delivery of an
original executed counterpart of this Trademark Security Agreement. Any party delivering an executed counterpart of this Trademark Security Agreement by telefacsimile or other electronic method of transmission also shall deliver an original executed
counterpart of this Trademark Security Agreement but the failure to deliver an original executed counterpart shall not affect the validity, enforceability, and binding effect of this Trademark Security Agreement.

THE PROVISIONS REGARDING CHOICE OF LAW AND VENUE, JURY TRIAL WAIVER, AND JUDICIAL REFERENCE SET FORTH IN SECTION 25 OF THE SECOND LIEN GUARANTY AND SECURITY AGREEMENT, AND SUCH PROVISIONS ARE INCORPORATED HEREIN BY THIS REFERENCE, MUTATIS
