WHEREAS, WMG Acquisition Corp., a Delaware corporation, has entered into a Security Agreement, dated as of November 1, 2012, made by the Grantors to the Collateral Agent (as amended, amended and restated, supplemented or otherwise modified from time to time, the “General Security Agreement”). Capitalized terms not otherwise defined herein have the meanings set forth in the General Security Agreement.

WHEREAS, under the terms of the General Security Agreement, the Grantors have granted to the Collateral Agent, for the ratable benefit of the Secured First Lien Parties, a security interest in, among other property, certain Trademarks (as defined below) of the Grantors, and have agreed as a condition thereof to execute this Security Agreement for recording with the United States Patent and Trademark Office.

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 confirms the grant to the Collateral Agent, for the ratable benefit of the Secured First Lien Parties, of a security interest in such Grantor’s right, title and interest in and to the following (all of the following items or types of property being herein collectively referred to as the “Trademark Collateral”), whether now owned or existing or hereafter acquired or arising:

(i) all trademarks, service marks, domain names, trade dress, logos, slogans, trade names, and other source identifiers, whether registered or unregistered, owned by the Grantor, (provided that no security interest shall be granted in United States intent-to-use trademark applications or service mark applications filed pursuant to Section 1(b) of the Lanham Act, 15 U.S.C. § 1051, unless and until an Amendment to Allege Use or a Statement of Use under Sections 1(c) and 1(d) of said Act has been filed and accepted), including, without limitation, each Trademark registration and application therefor, referred to in Schedule 1 hereto, and all of the goodwill of the business connected with the use of, or symbolized by, each Trademark;

(ii) all registrations and applications for registration for any Trademark, together with all renewals thereof;

(iii) any and all claims for damages and injunctive relief for past, present and future infringement, dilution, violation, misuse or breach with respect to any of the foregoing, with the right, but not the obligation, to sue for and collect, or otherwise recover, such damages; and

(iv) all Proceeds of, collateral for, income, royalties and other payments now or hereafter due and payable with respect to, and Supporting Obligations relating to, any and all of the foregoing.

SECTION 2. Security for Secured First Lien Obligations. The confirmation of the grant of continuing security interest in the Trademark Collateral by each Grantor under this Security Agreement secures the payment of all Secured First Lien Obligations of such Grantor, now or hereafter existing under or in respect of the Secured First Lien Agreements, whether direct or indirect, absolute or contingent, and whether for principal, reimbursement obligations, interest, premiums, penalties, fees, indemnifications, contract causes of action, costs, expenses or otherwise.

SECTION 3. Recordation. Each Grantor authorizes and requests that the Commissioner for Trademarks record this Security Agreement.

SECTION 4. Execution in Counterparts. This Security Agreement may be executed in any number of 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 Security Agreement has been executed and delivered by the Grantors for the purpose of recording the grant of security interest with the U.S. Patent and Trademark Office. The security interest confirmed hereby has been granted to the Collateral Agent in connection with the General Security Agreement and is expressly subject to the terms and conditions thereof and does not create any additional rights or obligations for any party hereto. The General Security Agreement (and all, rights and remedies of the Collateral Agent thereunder) shall remain in full force and effect in accordance with its terms.

SECTION 6. Governing Law. This Security Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.
