Any consent so delivered by the Responding Agent shall be binding on its successors and assigns.

(iii)   If any Collateral Agent or any Lender or Noteholder becomes the owner of any patent, trademark or proprietary information of any Credit Party as a result of the exercise of remedies by such Collateral Agent with respect to its Lien on such patent, trademark or proprietary information, then upon request of the Requesting Agent, the Responding Agent shall grant to the Requesting Agent a limited, nonexclusive royalty-free license (a “Disposition License”) to use any such patent, trademark, or proprietary information to the extent necessary to enforce any Lien held by the Requesting Agent upon any of the Revolver First Priority Collateral or the Notes First Priority Collateral, as applicable, and to the extent appropriate, in the good faith opinion of the Requesting Agent, to process, collect, ship, produce, store, complete, supply, lease, sell or otherwise dispose of any Revolver First Priority Collateral or Notes First Priority Collateral in any lawful manner (any such actions or activities taken by the Requesting Agent shall be at the expense of the Requesting Agent).

- 14 -

(ii)        the Requesting Agent is entitled to receive and use such information as against the Credit Parties and their suppliers, customers and contracts, and under applicable law, and, in doing so, will comply with all obligations imposed by law or contract in respect of the disclosure or use of such information.

(c)         If, upon enforcement of the Notes Collateral Agent’s Lien, such Notes Collateral Agent takes actual possession of any real or personal property of any Credit Party, then, if so requested by the Revolver Collateral Agent and upon reasonable advance notice, the Notes Collateral Agent will allow the Revolver Collateral Agent and its officers, employees, and agents reasonable and non-exclusive access to and use of such property for a period not exceeding 180 consecutive calendar days (the “Processing and Sale Period”), as necessary or reasonably appropriate to process, ship, produce, store, complete, supply, lease, sell, or otherwise dispose of, in any lawful manner, any inventory upon which the Revolver Collateral Agent holds a Lien, or to effectuate Account Collection, subject to the following conditions and limitations: (x) the Processing and Sale Period shall commence on the date the Notes Collateral Agent takes possession of such real property and shall terminate on the earlier of (i) the day that is 180 days thereafter; and (ii) the day on which all inventory (other than inventory acknowledged to have been abandoned by the Revolver Collateral Agent) has been removed from such property and the Account Collection has been fully effectuated and (y) the Revolver Collateral Agent, at its expense, shall repair any damage to such property caused by its exercise of the rights contained in this Section 6(c). Furthermore, the Notes Collateral Agent shall not sell or transfer such property during the Processing and Sale Period unless the purchaser or transferee agrees in writing to provide the access and use of such property for the remainder of the Processing and Sale Period.

(d)          The Notes Collateral Agent may condition its performance of any obligation set forth in this Section 6 upon its prior receipt (without cost to it) of:

(i)            such assurances as it may reasonably request to confirm that the performance of such obligation and all activities of the Revolver Collateral Agent or its officers, employees, and agents in connection therewith or incidental thereto:

(x)        will be permitted, lawful, and enforceable as against the Credit Parties and their suppliers, customers, and contracts and under applicable law and will be conducted in accordance with prudent manufacturing practices; and

(ii)          such indemnity or insurance as the Notes Collateral Agent may reasonably request in connection therewith.

- 15 -

disclosure or any proprietary information or other intellectual property by the Revolver Collateral Agent or its officers, employees, agents, successors, or assigns or any other damage to or misuse or loss of any property of any Credit Party as a result of any action taken or omitted by the Revolver Collateral Agent.

- 16 -

shall have the exclusive right to enforce rights, exercise remedies (including, without limitation, setoff, recoupment and the right to credit bid any Revolver Secured Obligations) and make determinations regarding release (subject to Section 4), disposition, or restrictions with respect to the Revolver First Priority Collateral without any consultation with or the consent of the Notes Collateral Agent.

Section 9.        Provisions Applicable After Bankruptcy.    Each party hereto agrees, solely in its capacity as a holder of Second Priority Collateral and without prejudice to its rights as a holder of First Priority Collateral, that in any bankruptcy proceeding of any Credit Party it will not:

(i)        object to or oppose (or encourage any other Person to object to or oppose) any motion for relief from the automatic stay by a holder of related First Priority Collateral;

(ii)        seek relief from the automatic stay with respect to its liens and security interests in its Second Priority Collateral without the prior express written consent of the Collateral Agent representing the holders of the related First Priority Collateral (which consent may be given or withheld by such Collateral Agent in its sole discretion) except, and then only to the extent that, such Collateral Agent has sought such relief with respect to the related First Priority Collateral and such holder seeks such relief with respect to its Second Priority Collateral in accordance with this Section 9 and the other terms and provisions of this Agreement;

(iii)        object to or oppose (or encourage any other Person to object to or oppose) any request by or grant to any holder of related First Priority Collateral of adequate protection with respect to such First Priority Collateral, including, without limitation, cash payments as adequate protection; provided, that if such holder of First Priority Collateral receives additional or replacement liens or administrative claims as adequate protection with respect to such First Priority Collateral, the holder of related Second Priority Collateral shall be entitled to the same additional or replacement liens or administrative claims on account of its liens and security interests in such Second Priority Collateral, but with the same relative junior and subordinated priority therein as set forth in this Agreement with respect to such Second Priority Collateral;

(iv)        except as set forth in clause (iii) above, seek or obtain adequate protection with respect to its Second Priority Collateral without the prior express written consent of the Collateral Agent representing the holders of the related First Priority Collateral (which consent may be given or withheld by such Collateral Agent in its sole discretion);

(v)        object to or oppose (or encourage any other Person to object to or oppose) any use of Collateral that constitutes First Priority Collateral, including cash collateral, under Section 363 of the Bankruptcy Code which is consented to by the Collateral Agent representing the holders of such First Priority Collateral;

- 18 -

financing that repays all or any portion of the Obligations having seniority hereunder on such Collateral; or

(vii)      object to or oppose (or encourage any other Person to object to or oppose), and will be deemed to have consented to, any sale or other disposition of Collateral that constitutes First Priority Collateral free and clear of its security interests, liens and other claims under Section 363, Section 1123(a)(5)(D) or any other provision of the Bankruptcy Code if the Collateral Agent representing the holders of such First Priority Collateral has consented to such sale or disposition and if the proceeds thereof are fully applied in accordance with the relative priorities set forth in this Agreement or, to the extent not so applied, the security interests, liens and claims of the holders of the related Second Priority Collateral attach to the proceeds thereof with the same relative junior and subordinated priority as set forth in this Agreement.

Section 10.         Separate Grants of Security and Separate Classification.

(a)        (i)        The Notes Collateral Agent, for itself and on behalf of the Notes Secured Creditors, and the Revolver Collateral Agent, for itself and on behalf of the Revolver Secured Creditors, acknowledges and agrees that the grants of Liens pursuant to the Revolver Security Documents and the Notes Security Documents constitute separate and distinct grants of Liens, and because of, among other things, their differing rights in the Collateral, the Notes Secured Obligations are fundamentally different from the Revolver Secured Obligations and must be separately classified in any plan of reorganization proposed or adopted in a Bankruptcy Proceeding. In furtherance of the foregoing, each of the Notes Collateral Agent, for itself and on behalf of the Notes Secured Creditors, and the Revolver Collateral Agent, for itself and on behalf of the Revolver Secured Creditors, agrees that the Notes Secured Creditors and the Revolver Secured Creditors will vote as separate classes in connection with any plan of reorganization in any Bankruptcy Proceeding and that no Collateral Agent, Administrative Agent, nor any Revolver Secured Creditor or Notes Secured Creditor will seek to vote with the other as a single class in connection with any plan of reorganization in any Proceeding.

(ii)        To further effectuate the intent of the parties as provided in this Section 10, if it is held that the claims of the Notes Secured Creditors and the Revolver Secured Creditors in respect of the Notes First Priority Collateral constitute only one secured claim (rather than separate classes of senior and junior secured claims), then each of the Notes Collateral Agent, for itself and on behalf of the Notes Secured Creditors, and the Revolver Collateral Agent, for itself and on behalf of the Revolver Secured Creditors, hereby acknowledges and agrees that, subject to Section 2, all distributions shall be made as if there were separate classes of senior and junior secured claims against the Company and other Credit Parties in respect of the Notes First Priority Collateral (with the effect being that, to the extent that the aggregate value of the Collateral securing the Notes Secured Obligations is sufficient (for this purpose ignoring all claims held by the Revolver Secured Creditors), the Notes Secured Creditors shall be entitled to receive, in addition to amounts distributed to them in respect of principal, pre-petition interest and other claims, all amounts owing in respect of post-petition interest, including any additional interest payable pursuant to the Indenture, arising from or related to a default, which is disallowed as a claim in any Bankruptcy Proceeding) before any distribution from the proceeds of the Notes First Priority Collateral is made in respect of the claims held by the Revolver Secured Creditors, hereby acknowledging and agreeing to turn over to the Notes Collateral Agent, for itself and on

- 19 -

behalf of the Notes Secured Creditors, amounts otherwise received or receivable by them to the extent necessary to effectuate the intent of this sentence, even if such turnover has the effect of reducing the claim or recovery of the Revolver Secured Creditors).

(iii)      To further effectuate the intent of the parties provided in this Section 10, if it is held that the claims of the Notes Secured Creditors and the Revolver Secured Creditors in respect of the Revolver First Priority Collateral constitute only one secured claim (rather than separate classes of senior and junior secured claims), then each of the Notes Collateral Agent, for itself and on behalf of the Notes Secured Creditors, and the Revolver Collateral Agent, for itself and on behalf of the Revolver Secured Creditors, hereby acknowledges and agrees that, subject to Section 2, all distributions shall be made as if there were separate classes of senior and junior secured claims against the Credit Parties in respect of the Revolver First Priority Collateral (with the effect being that, to the extent that the aggregate value of the Collateral securing the Revolver Secured Obligations is sufficient (for this purpose ignoring all claims held by the Notes Secured Creditors), the Revolver Secured Creditors shall be entitled to receive, in addition to amounts distributed to them in respect of principal, pre-petition interest and other claims, all amounts owing in respect of the post-petition interest, including any additional interest payable pursuant to the Revolving Credit Agreement, arising from or related to a default, which is disallowed as a claim in any Bankruptcy Proceeding) before any distribution from the proceeds of the Revolver First Priority Collateral is made in respect of the claims held by the Notes Secured Creditors, with the Notes Collateral Agent, for itself and on behalf of the Notes Secured Creditors, hereby acknowledging and agreeing to turn over to the Revolver Collateral Agent, for itself and on behalf of the Revolver Secured Creditors, amounts otherwise received or receivable by them to the extent necessary to effectuate the intent of this sentence, even if such turnover has the effect of reducing the claim or recovery of the Notes Secured Creditors).

Section 11.        Reliance; Disclaimers, Etc.

(a)      The Revolving Credit Agreement, the other Revolver Loan Documents and all related documents and agreements are deemed to have been executed and delivered, and all loans and other extensions of credit thereunder are deemed to have been made or incurred, in reliance upon this Agreement. The Notes Collateral Agent expressly waives all notice of the acceptance of and reliance on this Agreement by the Revolver Administrative Agent and the Revolver Secured Creditors.

(b)      The Indenture, the other Notes Documents and all related documents and agreements are deemed to have been executed and delivered, and all loans and other extensions of credit thereunder are deemed to have been made or incurred, in reliance upon this Agreement. The Revolver Administrative Agent expressly waives all notice of the acceptance of and reliance on this Agreement by the Trustee and the Notes Secured Creditors.

(c)      The Notes Collateral Agent, on the one hand, and the Revolver Administrative Agent, on the other hand, acknowledge and agree that neither has made any representation or warranty with respect to the execution, validity, legality, completeness, collectability or enforceability of the Revolving Credit Agreement or any other Revolver Loan Document or the Indenture or any other Notes Document. Except as otherwise provided in this Agreement, the Revolver Administrative Agent, on the one hand, and the Trustee and Notes Collateral Agent, on

- 20 -

the other hand, will be entitled to manage and supervise their respective loans, extensions of credit and extensions of indebtedness to Company and the Credit Parties, as the case may be, in accordance with law and their usual practices, modified from time to time as they deem appropriate.

(d)        Each party executing this Agreement agrees, for itself and on behalf of the relevant Secured Creditors, that (i) each Collateral Agent may act as the Revolver Administrative Agent or the Trustee, as the case may be, may direct (regardless of whether any Secured Creditor or any holder represented thereby agrees, disagrees or abstains with respect to such request), (ii) each Collateral Agent shall have no liability for acting in accordance with such request (provided such action does not, on its face, conflict with the express terms of this Agreement) and (iii) no Secured Creditor or any holder represented thereby shall have any liability to any other Secured Creditor or any holder represented thereby for any such request.

(e)        For the avoidance of doubt, each Collateral Agent may at any time request directions from the Revolver Administrative Agent or the Trustee (or the Notes Secured Creditors), as the case may be, as to any course of action or other matter relating hereto or as to any Security Document. Except as otherwise expressly specified in this Agreement, any such directions given by the Revolver Administrative Agent or the Trustee (or the Notes Secured Creditors) shall be binding on the Revolver Secured Creditors and the Notes Secured Creditors, respectively, for all purposes as described in this Agreement.

(f)        Notwithstanding the use of the term “Agent” herein and/or in any Credit Document, it is expressly understood and agreed that no Collateral Agent shall have any fiduciary responsibilities to any Secured Creditor by reason of this Agreement, any Security Agreement or any Credit Document and that each Collateral Agent is merely acting as the contractual representative of the applicable Secured Creditors with only those duties as are expressly set forth in this Agreement and the Security Agreements and Mortgages, as the case may be. In its capacity as the Secured Creditors’ contractual representative, no Collateral Agent assumes any fiduciary duties to any of the Secured Creditors and each is acting as an independent contractor, the rights and duties of which are limited to those expressly set forth in this Agreement and the Security Agreements and Mortgages, as the case may be. Each party hereto, for itself and on behalf of the relevant Secured Creditors hereby agrees not to assert a claim against a Collateral Agent on any agency theory or any other theory of liability for breach of fiduciary duty, all of which claims each party hereto, on behalf of each Secured Creditor, hereby waives. In addition, no Collateral Agent shall have any implied duties to any Secured Creditor or any obligation to any Secured Creditor to take any action hereunder or under any Security Agreement or Mortgage, except any action specifically provided herein or therein to be taken by such Collateral Agent.

Section 12.        Notices of Default and of Payment in Full of Indebtedness. Each party hereto agrees to use reasonable efforts to give to the others copies of any written notices of default, termination, demand for payment, redemption, acceleration, foreclosure, exercise of remedies and any other written notice of a like nature, which may be given under or pursuant to the terms of any of the applicable Credit Documents and of any notice contemplated under the definition of the term “Fully Paid” herein, in each case concurrently with, or as soon as practicable after, the giving of such notice to such party; provided, however, that no failure of

- 21 -

any party to give a copy of any such notice as provided herein shall in any event affect the validity or effectiveness of the notice or render the party liable to any other party in any respect or relieve any party of its obligations and agreements contained herein; provided, further, however, that in no event shall this Section 11 require the delivery of any notices to Company.

Section 13.        Notices.  All notices and communications hereunder shall be sent or delivered by mail, telecopier or overnight courier service and all such notices and communications shall (i) in the case of a notice or communication sent by mail, be effective three Business Days following deposit with proper prepaid postage in the mail; (ii) in the case of a notice or communication sent by telecopier, be effective when sent, provided appropriate confirmation is received by the sender; and (iii) in the case of a notice or communication sent by overnight courier, be effective on the date of delivery.

Lenders (as defined in the Revolving Credit Agreement) as may be required pursuant to Section 12.1 of the Revolving Credit Agreement) and the Notes Collateral Agent (with the written consent of a majority of the Noteholders required pursuant to the Indenture), except that written consent of the Company shall be required if the amendment, modification or waiver would impose, or have the effect of imposing, on the Company more restrictive covenants or greater obligations than those applicable to the Company under this Agreement or any of the Credit Documents as of the date hereof. No waiver shall be deemed to be made by any Collateral Agent of its rights hereunder, unless the same shall be in writing signed by such Collateral Agent (acting in accordance with this Section 21), and each waiver, if any, shall be a waiver only with respect to the specific instance involved and shall in no way impair the rights of such Collateral Agent, in any other respect at any other time.

Section 23.        Miscellaneous.    This Agreement is solely for the purpose of defining the relative rights and priorities of the parties hereto and that of the Revolver Secured Creditors and the Notes Secured Creditors and their respective successors and assigns with respect to the Collateral, and no other person, firm, entity or corporation shall have any right, benefit, priority or interest under, or because of the existence of, this Agreement. It is expressly acknowledged and agreed that the Revolver Collateral Agent and the Notes Collateral Agent may be referred to in one or more Security Documents by other defined terms, including, without limitation, the “Revolving Credit Agreement Collateral Agent”. No such use of such different terminology is intended to affect the enforcement of this Agreement or any other Security Document. This Agreement shall not inure to the benefit of the Company or any Subsidiary thereof, or their respective successors and assigns. The parties hereto agree and acknowledge that they shall not challenge or question in any proceeding the validity, perfection, priority or enforceability of this Agreement, as a whole, or any term or provision contained herein. Without limiting the terms of this Agreement, the parties intend that this Agreement shall be enforceable in a bankruptcy proceeding, including pursuant to Section 510(a) of the Bankruptcy Code.

Section 24.        Termination.  Upon the one hundred twenty-first (121st) day after the earlier of all Notes Obligations or Revolver Obligations have been Fully Paid, this Agreement shall immediately terminate and cease to be effective and the Collateral Agents, the Revolver Administrative Agent, the Trustee, the Lenders, the Noteholders and the Credit Parties shall be released from their respective obligations hereunder (other than such obligations that by their terms are stated to survive the termination of this Agreement); provided, however, this Agreement shall be automatically reinstated if at any time payment of, in whole or in part, any of the Obligations are challenged by the initiation of any suit or proceeding by any party, or are rescinded or must otherwise be restored or returned by any Administrative Agent or any Lender as a preference, fraudulent conveyance or otherwise under any bankruptcy, insolvency or similar law, or under any other state or federal law, the common law or any ruling in equity, all as though such payment had not been made, and in such event, all reasonable documented costs and expenses (including, without limitation, any reasonable documented legal fees and disbursements) incurred by any Administrative Agent or any Lender in defending any such action or proceeding or enforcing such reinstatement shall be deemed included as part of the Revolver Obligations or Notes Obligations, as the case may be.
