the Grantors) have been assigned to the Trustee for the benefit of the Noteholders or that the Trustee has a security interest therein, and (b) collect the General Intangibles and Negotiable Collateral (other than any of the foregoing that constitute proceeds of accounts receivable or inventory of the Grantors) directly, and any collection costs and expenses shall constitute part of such Grantor’s Secured Obligations under the Indenture. Each Grantor agrees that it will hold in trust for the Trustee, as the Trustee’s trustee, any funds that it receives and, subject to the provisions of the Intercreditor Agreement, immediately will deliver such funds to the Trustee in their original form as received by such Grantor.

14. Remedies. Upon the occurrence and during the continuance of an Event of Default, subject to the provisions of the Intercreditor Agreement:

(a) The Trustee may exercise in respect of the Collateral, in addition to other rights and remedies provided for herein, in the other Loan Documents, or otherwise available to it, all the rights and remedies of a secured party upon a default under the UCC. Without limiting the generality of the foregoing, each Grantor expressly agrees that in any such event the Trustee, without demand of performance or other demand, advertisement or notice of any kind (except a notice specified below of time and place of public or private sale or as expressly required by the Indenture) to or upon any of the Grantors or any other Person (all and each of which demands, advertisements and notices are hereby expressly waived to the maximum extent permitted by the UCC and other Applicable Law), may take immediate possession of the Collateral and (i) require the Grantors to, and each Grantor hereby agrees that it will at its own expense and upon request of the Trustee forthwith, assemble all or part of the Collateral as directed by the Trustee and make it available to the Trustee at one or more locations where such Grantor regularly maintains Inventory and (ii) without notice except as specified below, sell the Collateral or any part thereof in one or more parcels at public or private sale, at any of the Trustee’s offices or elsewhere, for cash, on credit or for future delivery, and upon such other terms as the Trustee may deem commercially reasonable. Each Grantor agrees that, to the extent notice of sale shall be required by law, at least fifteen (15) days’ notice to any of the Grantors of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification and specifically such notice shall constitute a reasonable “authenticated notification of disposition” within the meaning of Section 9-611 of the Uniform Commercial Code, as in effect from time to time in any applicable jurisdiction. The Trustee shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Trustee may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned.

(b) The Trustee is hereby granted a license or other right to use, without liability for royalties or any other charge, each Grantor’s labels, Patents, Copyrights, rights of use of any name, trade secrets, trade names, Trademarks, service marks and advertising matter, URLs, domain names, industrial designs, other industrial or intellectual property or any property of a similar nature, whether owned by any of the Grantors or with respect to which any of the Grantors have rights under license, sublicense or other agreements, as it pertains to the Collateral, in preparing for sale, advertising for sale and selling any Collateral, and each Grantor’s rights under all licenses and all franchise agreements shall inure to the benefit of the Trustee.

(c) Any cash held by the Trustee as Collateral and all cash proceeds received by the Trustee in respect of any sale of, collection from, or other realization upon all or any part of the Collateral shall be applied in whole or in part by the Trustee against all or any amounts due under the Secured Obligations in such order as may be set forth in the Indenture. Any surplus of such cash or cash proceeds held by the Trustee and remaining after payment in full of all the Secured Obligations shall be delivered to the Grantors.

(d) Each Grantor hereby acknowledges that the Secured Obligations arose out of a commercial transaction, and agrees that, if an Event of Default shall occur, the Trustee shall have the right to an immediate writ of possession without notice of a hearing. The Trustee shall have the right to the appointment of a receiver for the properties and assets of each of the Grantors, and each Grantor hereby consents to such rights and such appointment and hereby waives any objection such Grantors may have thereto or the right to have a bond or other security posted by the Trustee.

15. Remedies Cumulative. Each right, power, and remedy of the Trustee as provided for in this Agreement or in the other Note Documents or now or hereafter existing at law or in equity or by statute or otherwise shall be cumulative and concurrent and shall be in addition to every other right, power, or remedy provided for in this Agreement or in the other Note Documents or now or hereafter existing at law or in equity or by statute or otherwise, and the exercise or beginning of the exercise by the Trustee, of any one or more of such rights, powers or remedies shall not preclude the simultaneous or later exercise by the Trustee of any or all such other rights, powers or remedies.

16. Marshalling. The Trustee shall not be required to marshal any present or future collateral security (including, without limitation, the Collateral) for, or other assurances of payment of, the Secured Obligations or any of them or to resort to such collateral security or other assurances of payment in any particular order, and all of its rights and remedies hereunder and in respect of such collateral security and other assurances of payment shall be cumulative and in addition to all other rights and remedies, however existing or arising. To the extent that it lawfully may, each Grantor hereby agrees that it will not invoke any law relating to the marshalling of collateral which might cause delay in or impede the enforcement of the Trustee’s rights and remedies under this Agreement or under any other instrument creating or evidencing any of the Secured Obligations or under which any of the Secured Obligations is outstanding or by which any of the Secured Obligations is secured or payment thereof is otherwise assured, and, to the extent that it lawfully may, each Grantor hereby irrevocably waives the benefits of all such laws.

17. Indemnity and Expenses.

(a) Each Grantor, jointly and severally, agrees to indemnify the Trustee, the Initial Purchasers and the Noteholders from and against all claims, lawsuits and liabilities (including reasonable attorneys’ fees) growing out of or resulting from this Agreement (including, without limitation, enforcement of this Agreement) or any other Note Document to which such Grantor is a party, except claims, losses or liabilities resulting from the gross negligence or willful misconduct of the party seeking indemnification as determined by a final non-appealable order of a court of competent jurisdiction. This provision shall survive the termination of this Agreement and the Indenture and the repayment of the Secured Obligations.

(b) The Grantors shall, upon demand, pay to the Trustee, jointly and severally, the amount of any and all expenses, including, without limitation, the reasonable fees and expenses of its counsel incurred and the fees and expenses of any experts and agents, which the Trustee may incur in connection with (i) the administration of this Agreement, (ii) the custody, preservation, use or operation of, or, upon an Event of Default, the sale of, collection from, or other realization upon, any of the Collateral in accordance with this Agreement and the other Note Documents, (iii) the exercise or enforcement of any of the rights of the Trustee hereunder or (iv) the failure by any of the Grantors to perform or observe any of the provisions hereof.

18. Merger, Amendments; Etc. THIS WRITTEN AGREEMENT, TOGETHER WITH THE OTHER NOTE DOCUMENTS, REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES. No waiver of any provision of this Agreement, and no consent to any departure by any of the Grantors herefrom, shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. No amendment of any provision of this Agreement shall be effective unless the same shall be in writing and signed by the Trustee and each of the Grantors to which such amendment applies.

19. Addresses for Notices. All notices and other communications provided for hereunder shall be given in the form and manner and delivered to the Trustee at its address specified in the Indenture, and to any of the Grantors at their respective addresses specified in the Indenture, or, as to any party, at such other address as shall be designated by such party in a written notice to the other party.

20. Continuing Security Interest: Assignments under Indenture. This Agreement shall create a continuing security interest in the Collateral and shall (a) remain in full force and effect until the Secured Obligations have been paid in full in cash or otherwise satisfied to the satisfaction of the Trustee, (b) be binding upon each of the Grantors, and their respective successors and assigns, and (c) inure to the benefit of, and be enforceable by, the Trustee, and its successors, transferees and assigns. Upon payment in full in cash, or other satisfaction to the satisfaction of the Trustee, of the Secured Obligations, the security interest granted hereby shall terminate and all rights to the Collateral shall immediately revert to the Grantors or any other Person entitled thereto. At such time as the Secured Obligations have been paid in full in cash or otherwise satisfied to the satisfaction of the Trustee, the Trustee will promptly authorize the filing of appropriate termination statements to terminate the Security Interest. No transfer or renewal, extension, assignment or termination of this Agreement, the Indenture, any other Note Document or any other instrument or document executed and delivered by the Company or any of the Grantors to the Trustee, nor the taking of further security, nor the retaking or re-delivery of the Collateral to the Company and the Grantors, or any of them, by the Trustee, nor any other act of the Noteholders, or any of them, shall release any of the Grantors from any obligation, except a release or discharge executed in writing by the Trustee with respect to such obligation or

payment of such obligation or upon payment in full in cash, or other satisfaction to the satisfaction of the Trustee, of the Secured Obligations. The Trustee shall not by any act, delay, omission or otherwise, be deemed to have waived any of its rights or remedies hereunder, unless such waiver is in writing and signed by the Trustee and then only to the extent therein set forth. A waiver by the Trustee of any right or remedy on any occasion shall not be construed as a bar to the exercise of any such right or remedy which the Trustee would otherwise have had on any other occasion. In the event of any sale of Collateral permitted by Section 11.03 of the Indenture, or any other permitted sale of all or any portion of the Collateral that may be permitted by the Trustee, the Trustee will, promptly upon the written request of the appropriate Grantor, execute and deliver to the relevant Grantor termination statements provided to the Trustee to terminate the Security Interest in such Collateral.

21. Governing Law. This Agreement is intended to take effect as a sealed instrument and shall be construed in accordance with and governed by the laws of the State of New York, except to the extent that the validity or perfection of the security interest hereunder, or remedies hereunder, in respect of any particular Collateral are governed by the laws of a jurisdiction other than the State of New York.

22. New Subsidiaries. Pursuant to Section 4.20 of the Indenture, any new direct or indirect Subsidiary (whether by acquisition, creation or designation) of the Company is required to enter into this Agreement by executing and delivering in favor of the Trustee an instrument in the form of Annex 1 attached hereto. Upon the execution and delivery of Annex 1 by such new Subsidiary, such Subsidiary shall become a Grantor hereunder with the same force and effect as if originally named as a Grantor herein. The execution and delivery of any instrument adding an additional Grantor as a party to this Agreement shall not require the consent of any Grantor hereunder. The rights and obligations of each Grantor hereunder shall remain in full force and effect notwithstanding the addition of any new Grantor hereunder.

23. Trustee. Each reference herein to any right granted to, benefit conferred upon or power exercisable by the “Trustee” shall be a reference to Trustee for the benefit of the Noteholders, and each action taken or right exercised hereunder shall be deemed to have been so taken or exercised by Trustee for the benefit of the Noteholders.

24. Miscellaneous.

(a) This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such separate counterparts shall together constitute but one and the same instrument. In proving this Agreement or any other Loan Document in any judicial proceedings, it shall not be necessary to produce or account for more than one such counterpart signed by the party against whom such enforcement is sought. Any signatures delivered by a party by facsimile transmission or by e-mail transmission shall be deemed an original signature hereto.

(b) Any provision of this Agreement which is prohibited or unenforceable shall be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof in that jurisdiction or affecting the validity or enforceability of such provision in any other jurisdiction.

(c) Headings used in this Agreement are for convenience only and shall not be used in connection with the interpretation of any provision hereof.

(d) The pronouns used herein shall include, when appropriate, either gender and both singular and plural, and the grammatical construction of sentences shall conform thereto.

(e) Notwithstanding anything herein to the contrary, (i) the liens and security interests granted to the Trustee pursuant to this Agreement are expressly subject and subordinate to the liens and security interests granted to the Administrative Agent (and its permitted successors and assigns), for the benefit of the credit parties, pursuant to the Credit Agreement and the related security documents dated as of September 9, 2004 (as further amended, restated, refinanced, replaced, supplemented or otherwise modified from time to time), by and among the Company, the Administrative Agent, the lenders and the other credit parties party thereto and the other parties party thereto and (ii) the exercise of any right or remedy by the Trustee hereunder is subject to the limitations and provisions of the Intercreditor Agreement. In the event of any conflict between the terms of the Intercreditor Agreement and the terms of this Agreement, the terms of the Intercreditor Agreement shall govern.

(f) In connection with its appointment and acting hereunder, the Trustee is entitled to all rights, privileges, protections, benefits and immunities provided to it under the Indenture.

(c) all products and proceeds of the foregoing, including, without limitation, any claim by the Grantor against third parties for past, present or future infringement of any Patent or any Patent licensed under any Intellectual Property License.

3. SECURITY AGREEMENT. The security interests granted pursuant to this Patent Security Agreement are granted in conjunction with the security interests granted to the Trustee, for the benefit of the Noteholders, pursuant to the Security Agreement. The Grantor hereby acknowledges and affirms that the rights and remedies of the Trustee with respect to the security interest in the Patent Collateral made and granted hereby are more fully set forth in the Security Agreement, the terms and provisions of which are incorporated by reference herein as if fully set forth herein.

4. AUTHORIZATION TO SUPPLEMENT. If any Grantor shall obtain rights to any new patentable inventions or become entitled to the benefit of any patent application or patent for any reissue, division, or continuation, of any patent, the provisions of this Patent Security Agreement shall automatically apply thereto. The Grantors shall give prompt notice in writing to the Trustee with respect to any such new patent rights. Without limiting the Grantors’ obligations under this Section 4, the Grantors hereby authorize the Trustee unilaterally to modify this Agreement by amending Schedule I to include any such new patent rights of such Grantor. Notwithstanding the foregoing, no failure to so modify this Patent Security Agreement or amend Schedule I shall in any way affect, invalidate or detract from the Trustee’s continuing security interest in all Collateral, whether or not listed on Schedule I.

5. COUNTERPARTS. This Patent Security Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such separate counterparts shall together constitute but one and the same instrument. In proving this Patent Security Agreement or any other Note Document in any judicial proceedings, it shall not be necessary to produce or account for more than one such counterpart signed by the party against whom such enforcement is sought. Any signatures delivered by a party by facsimile transmission or by e-mail transmission shall be deemed an original signature hereto.

6. Notwithstanding anything herein to the contrary, (i) the liens and security interests granted to the Trustee pursuant to this Patent Security Agreement are expressly subject and subordinate to the liens and security interests granted to the Administrative Agent (and its permitted successors and assigns), for the benefit of the credit parties, pursuant to the Credit Agreement and the related security documents dated as of September 9, 2004 (as further amended, restated, refinanced, replaced, supplemented or otherwise modified from time to time), by and among the Company, the Administrative Agent, the lenders and the other credit parties party thereto and the other parties party thereto and (ii) the exercise of any right or remedy by the Trustee hereunder is subject to the limitations and provisions of the Intercreditor Agreement. In the event of any conflict between the terms of the Intercreditor Agreement and the terms of this Agreement, the terms of the Intercreditor Agreement shall govern.
