Terms defined in the Credit Agreement and not otherwise defined herein are used herein as defined in the Credit Agreement.

WHEREAS, as a condition precedent to the making of Loans by the Lenders, each Grantor has executed and delivered that certain Pledge and Security Agreement, dated as of November 14, 2016, by and among the Grantors and Administrative Agent (as amended, restated, supplemented or otherwise modified from time to time, the “Security Agreement”); and

WHEREAS, under the terms of the Security Agreement, each Grantor has granted a security interest in, among other property, certain intellectual property of such Grantor to Administrative Agent, and has agreed as a condition thereof to execute this IP Security Agreement covering such intellectual property for recording with the U.S. Patent and Trademark Office, the United States Copyright Office and other governmental authorities.

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, each Grantor agrees as follows:

SECTION 1.          Grant of Security. Each Grantor hereby grants to Administrative Agent a security interest in and to all of Grantor’s right, title and interest in and to the following (the “Collateral”):

(i)          the United States, international and foreign patents, patent applications and patent licenses set forth in Schedule A hereto (as such Schedule A may be supplemented from time to time by supplements to the Security Agreement and this IP Security Agreement, each such supplement, an “IP Security Agreement Supplement”), executed and delivered by such Grantor to Administrative Agent from time to time), together with all reissues, divisions, continuations, continuations-in-part, extensions and reexaminations thereof, and all rights therein provided by international treaties or conventions (the “Patents”);

(ii)         The United States and foreign trademark and service mark registrations, applications, and licenses set forth in Schedule B hereto (as such Schedule B may be supplemented from time to time by an IP Security Agreement Supplement executed and delivered by such Grantor to Administrative Agent from time to time) (the “Trademarks”);

(iii)        the copyrights, United States and foreign copyright registrations and applications and copyright licenses set forth in Schedule C hereto (as such Schedule C may be supplemented from time to time by an IP Security Agreement Supplement executed and delivered by such Grantor to Administrative Agent from time to time) (the “Copyrights”);

(iv)        any and all claims for damages for past, present and future infringement, misappropriation or breach with respect to the Patents, Trademarks and Copyrights, with the right, but not the obligation, to sue for and collect, or otherwise recover, such damages; and

(v)          any and all proceeds of the foregoing.

Notwithstanding the foregoing, however, the Collateral shall not include any intent-to-use trademark, prior to the filing of a “Statement of Use” with respect thereto if and solely to the extent that (and so long as) any such intent-to-use trademark application would be rendered void by the attachment or creation of a security interest in the right, title or interest of such Grantor therein).

SECTION 2.          Security for Obligations. The grant of a security interest in the Collateral by each Grantor under this IP Security Agreement secures the payment of the Obligations (as defined in the Credit Agreement) and the Guaranteed Obligations (as defined in the Guaranty) of each Grantor now or hereafter existing, whether direct or indirect, absolute or contingent, and whether for principal, reimbursement obligations, interest (including any interest that accrues after the commencement of bankruptcy), premiums, penalties, fees, indemnifications, contract causes of action, costs, expenses or otherwise.

SECTION 3. Recordation. Each Grantor authorizes and requests that the Register of Copyrights, the Commissioner of Patents and Trademarks and any other applicable government office record this IP Security Agreement.

SECTION 4. Execution in Counterparts. This Agreement may be executed in counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement.

SECTION 5.          Grants, Rights and Remedies. This IP Security Agreement has been entered into in conjunction with the provisions of the Security Agreement. Each Grantor does hereby acknowledge and confirm that the grant of the security interest hereunder to, and the rights and remedies of, the Administrative Agent with respect to the Collateral are more fully set forth in the Security Agreement, the terms and provisions of which are incorporated herein by reference as if fully set forth herein.

SECTION 6. Governing Law. This IP Security Agreement shall be governed by, and construed and enforced in accordance with, the Law of the State of New York without regard to principles of conflict of Law.
