Accordingly, the Collateral Agent and the Grantor agree as follows:

SECTION 1.    Grant of Security.

SECTION 2.    Security for the Secured Obligations. The grant of a security interest in the Collateral by the Grantor under this Supplement secures the payment of all amounts that constitute part of the Secured Obligations and would be owed to the Collateral Agent or the Secured Parties but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving the Grantor.

SECTION 3.    Recordation. The Grantor authorizes and requests that the Register of Copyrights, the Commissioner for Patents, the Commissioner for Trademarks and any other applicable governmental officer located in the United States record this Supplement. Separate agreements should be entered in respect of patents, trademarks, and copyrights.

SECTION 4.    Grants. Rights and Remedies. This Supplement has been entered into in conjunction with the provisions of the Security Agreement. The Grantor does hereby acknowledge and confirm that the grant of the security interest hereunder to, and the rights and

remedies of, the Collateral 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. In the event of any conflict between the terms of this Supplement and the terms of the Security Agreement, the terms of the Security Agreement shall govern.

SECTION 5.    Counterparts. This Supplement may be executed by one or more of the parties to this Supplement on any number of separate counterparts (including by facsimile or other electronic transmission (i.e. a “pdf’ or “tif’)), and all of said counterparts taken together shall be deemed to constitute one and the same instrument.

Any provision of this Supplement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof and in the Security Agreement, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. The parties hereto 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.    Notices. All notices, requests and demands pursuant hereto shall be made in accordance with Section 11.3 of the Term Loan Agreement.
