Priorities and Agreements with Respect to Shared Collateral

SECTION 2.01 Priority of Claims. (a) Anything contained herein or in any of the Secured Credit Documents to the contrary notwithstanding (but subject to Section 1.03), if an Event of Default has occurred and is continuing, and the Collateral Agent or any First Lien Secured Party is taking action to enforce rights in respect of any Shared Collateral, or any distribution is made in respect of any Shared Collateral in any Bankruptcy Case of the Company or any other Grantor or any First Lien Secured Party receives any payment pursuant to any intercreditor agreement (other than this Agreement) with respect to any Shared Collateral, the proceeds of any sale, collection or other liquidation of any such Collateral by any First Lien Secured Party or received by the Collateral Agent or any First Lien Secured Party pursuant to any such intercreditor agreement with respect to such Shared Collateral and proceeds of any such distribution (subject, in the case of any such distribution, to the sentence immediately following) to which the First Lien Obligations are entitled under any intercreditor agreement (other than this Agreement) (all proceeds of any sale, collection or other liquidation of any Collateral and all proceeds of any such distribution being collectively referred to as “Proceeds”), shall be applied (i) FIRST, to the payment of all amounts owing to the Collateral Agent (in its capacity as such) pursuant to the terms of any Secured Credit Document, (ii) SECOND, subject to Section 1.03, to the payment in full of the First Lien Obligations of each Series on a ratable basis in accordance with the terms of the applicable Secured Credit Documents and (iii) THIRD, after payment of all First Lien Obligations, to the Company and the other Grantors or their successors or assigns, as their interests may appear, or to whosoever may be lawfully entitled to receive the same, or as a court of competent jurisdiction may direct. Notwithstanding the foregoing, with respect to any Shared Collateral for which a third party (other than a First Lien Secured Party) has a lien or security interest that is junior in priority to the security interest of any Series of First Lien

Obligations but senior (as determined by appropriate legal proceedings in the case of any dispute) to the security interest of any other Series of First Lien Obligations (such third party an “Intervening Creditor”), the value of any Shared Collateral or Proceeds which are allocated to such Intervening Creditor shall be deducted on a ratable basis solely from the Shared Collateral or Proceeds to be distributed in respect of the Series of First Lien Obligations with respect to which such Impairment exists.

(b) It is acknowledged that the First Lien Obligations of any Series may, subject to the limitations set forth in the then extant Secured Credit Documents, be increased, extended, renewed, replaced, restated, supplemented, restructured, repaid, refunded, Refinanced or otherwise amended or modified from time to time, all without affecting the priorities set forth in Section 2.01(a) or the provisions of this Agreement defining the relative rights of the First Lien Secured Parties of any Series.

(c) Notwithstanding the date, time, method, manner or order of grant, attachment or perfection of any Liens securing any Series of First Lien Obligations granted on the Shared Collateral and notwithstanding any provision of the Uniform Commercial Code of any jurisdiction, or any other applicable law or the Secured Credit Documents or any defect or deficiencies in the Liens securing the First Lien Obligations of any Series or any other circumstance whatsoever (but, in each case, subject to Section 1.03), each First Lien Secured Party hereby agrees that the Liens securing each Series of First Lien Obligations on any Shared Collateral shall be of equal priority.

(d) Notwithstanding anything in this Agreement or any other First Lien Security Documents to the contrary, Collateral consisting of cash and Cash Equivalents pledged to secure Credit Agreement Obligations consisting of reimbursement obligations in respect of Letters of Credit or otherwise held by the Administrative Agent or the Collateral Agent pursuant to Section 3.03(b), 4.02(b), 5.01(b) or 5.02(a) of the Credit Agreement (or any equivalent successor provision) shall be applied as specified in such Section of the Credit Agreement (or the arrangements specified therein) and will not constitute Shared Collateral.

SECTION 2.02 Actions with Respect to Shared Collateral; Prohibition on Contesting Liens.

Security Document, applicable law or otherwise, it being agreed that only the Collateral Agent, acting on the instructions of the Applicable Authorized Representative and in accordance with the applicable First Lien Security Documents, shall be entitled to take any such actions or exercise any such remedies with respect to Shared Collateral. Notwithstanding the equal priority of the Liens, the Collateral Agent (acting on the instructions of the Applicable Authorized Representative) may deal with the Shared Collateral as if such Applicable Authorized Representative had a senior Lien on such Collateral. No Non-Controlling Authorized Representative or Non-Controlling Secured Party will contest, protest or object to any foreclosure proceeding or action brought by the Collateral Agent, the Applicable Authorized Representative or the Controlling Secured Party or any other exercise by the Collateral Agent, the Applicable Authorized Representative or the Controlling Secured Party of any rights and remedies relating to the Shared Collateral, or to cause the Collateral Agent to do so. The foregoing shall not be construed to limit the rights and priorities of any First Lien Secured Party, the Collateral Agent or any Authorized Representative with respect to any collateral not constituting Shared Collateral.

(b) Each of the Authorized Representatives agrees that it will not accept any Lien on any collateral for the benefit of any Series of First Lien Obligations (other than funds deposited for the discharge or defeasance of any Additional First Lien Agreement to the extent permitted by the applicable Secured Credit Documents) other than pursuant to the First Lien Security Documents and pursuant to Section 3.03(b), 4.02(b), 5.01(b) or 5.02(a) of the Credit Agreement, and by executing this Agreement (or a Joinder Agreement), each Authorized Representative and the Series of First Lien Secured Parties for which it is acting hereunder agree to be bound by the provisions of this Agreement and the other First Lien Security Documents applicable to it.

SECTION 2.03 No Interference; Payment Over. (a) Each First Lien Secured Party agrees that (i) it will not challenge or question in any proceeding the validity or enforceability of any First Lien Obligations of any Series or any First Lien Security Document or the validity, attachment, perfection or priority of any Lien under any First Lien Security Document or the validity or enforceability of the priorities, rights or duties established by or other provisions of this Agreement; (ii) it will not take or cause to be taken any action the purpose or intent of which is, or could be, to interfere, hinder or delay, in any manner, whether by judicial proceedings or otherwise, any sale, transfer or other disposition of the Shared Collateral by the Collateral Agent, (iii) except as provided in Section 2.02, it shall have no right to (A) direct the Collateral Agent or any other First Lien Secured Party to exercise any right, remedy or power with respect to any Shared Collateral (including pursuant to any intercreditor agreement) or (B) consent to the exercise by the Collateral Agent or any other First Lien Secured Party of any right, remedy or power with respect to any Shared Collateral, (iv) it will not institute

any suit or assert in any suit, bankruptcy, insolvency or other proceeding any claim against the Collateral Agent or any other First Lien Secured Party seeking damages from or other relief by way of specific performance, instructions or otherwise with respect to any Shared Collateral, and none of the Collateral Agent, any Applicable Authorized Representative or any other First Lien Secured Party shall be liable for any action taken or omitted to be taken by the Collateral Agent, such Applicable Authorized Representative or other First Lien Secured Party with respect to any Shared Collateral in accordance with the provisions of this Agreement, (v) it will not seek, and hereby waives any right, to have any Shared Collateral or any part thereof marshaled upon any foreclosure or other disposition of such Collateral and (vi) it will not attempt, directly or indirectly, whether by judicial proceedings or otherwise, to challenge the enforceability of any provision of this Agreement; provided that nothing in this Agreement shall be construed to prevent or impair the rights of any of the Collateral Agent or any other First Lien Secured Party to enforce this Agreement.

(b) Each First Lien Secured Party hereby agrees that if it shall obtain possession of any Shared Collateral or shall realize any proceeds or payment in respect of any such Shared Collateral, pursuant to any First Lien Security Document or by the exercise of any rights available to it under applicable law or in any Insolvency or Liquidation Proceeding or through any other exercise of remedies (including pursuant to any intercreditor agreement), at any time prior to the Discharge of each of the First Lien Obligations, then it shall hold such Shared Collateral, proceeds or payment in trust for the other First Lien Secured Parties and promptly transfer such Shared Collateral, proceeds or payment, as the case may be, to the Collateral Agent, to be distributed in accordance with the provisions of Section 2.01.

SECTION 2.04 Automatic Release of Liens; Amendments to First Lien Security Documents. (a) If, at any time the Collateral Agent forecloses upon or otherwise exercises remedies against any Shared Collateral resulting in a sale or disposition thereof, then (whether or not any Insolvency or Liquidation Proceeding is pending at the time) the Liens in favor of the Collateral Agent for the benefit of each Series of First Lien Secured Parties upon such Shared Collateral will automatically be released and discharged; provided that any proceeds of any Shared Collateral realized therefrom shall be applied pursuant to Section 2.01.

(b) Each First Lien Secured Party agrees that the Collateral Agent may enter into any amendment (and, upon request by the Collateral Agent, each Authorized Representative shall sign a consent to such amendment) to any First Lien Security Document, so long as the Collateral Agent receives a certificate of the Company stating that such amendment is permitted by the terms of each then extant Secured Credit Document (and the Collateral Agent may conclusively rely on any such certificate). Additionally, each First Lien Secured Party agrees that the Collateral Agent may enter into any amendment (and, upon request by the Collateral Agent, each Authorized Representative shall sign a consent to such amendment) to any First Lien Security Document solely as such First Lien Security Document relates to a particular Series of First Lien Obligations so long as (x) such amendment is in accordance with the Secured Credit Document pursuant to which such Series of First Lien Obligations was incurred, (y) such amendment does not adversely affect the First Lien Secured Parties of any other Series and (z) the Collateral Agent receives a certificate of the Company stating that such amendment is permitted by the terms of each then extant Secured Credit Document (and the Collateral Agent may conclusively rely on any such certificate).

(c) Each Authorized Representative agrees to execute and deliver (at the sole cost and expense of the Grantors) all such authorizations and other instruments as shall reasonably be requested by the Collateral Agent to evidence and confirm any release of Shared Collateral or amendment to any First Lien Security Document provided for in this Section.

SECTION 2.05 Certain Agreements with Respect to Bankruptcy or Insolvency Proceedings.

(b) If the Company and/or any other Grantor shall become subject to a case (a “Bankruptcy Case”) under the Bankruptcy Code and shall, as debtor(s)-in-possession, move for approval of financing (“DIP Financing”) to be provided by one or more lenders (the “DIP Lenders”) under Section 364 of the Bankruptcy Code or any equivalent provision of any other Bankruptcy Law or the use of cash collateral under Section 363 of the Bankruptcy Code or any equivalent provision of any other Bankruptcy Law, each First Lien Secured Party agrees that it will raise no objection to any such financing or to the Liens on the Shared Collateral securing the same (“DIP Financing Liens”) or to any use of cash collateral that constitutes Shared Collateral, unless any Controlling Secured Party, or an Authorized Representative of any Controlling Secured Party, shall then oppose or object to such DIP Financing or such DIP Financing Liens or use of cash collateral (and (i) to the extent that such DIP Financing Liens are senior to the Liens on any such Shared Collateral for the benefit of the Controlling Secured Parties, each Non-Controlling Secured Party will subordinate its Liens with respect to such Shared Collateral on the same terms as the Liens of the Controlling Secured Parties (other than any Liens of any First Lien Secured Parties constituting DIP Financing Liens) are subordinated thereto, and (ii) to the extent that such DIP Financing Liens rank pari passu with the Liens on any such Shared Collateral granted to secure the First Lien Obligations of the Controlling Secured Parties, each Non-Controlling Secured Party will confirm the priorities with respect to such Shared Collateral as set forth herein), in each case so long as (A) the First Lien Secured Parties of each Series retain the benefit of their Liens on all such Shared Collateral pledged to the DIP Lenders, including proceeds thereof arising after the commencement of such proceeding, with the same priority vis-a-vis all the other First Lien Secured Parties (other than any Liens of the First Lien Secured Parties constituting DIP Financing Liens) as existed prior to the commencement of the Bankruptcy Case, (B) the First Lien Secured Parties of each Series are granted Liens on any additional collateral pledged to any First Lien Secured Parties as adequate protection or otherwise in connection with such DIP Financing or use of cash collateral, with the same priority vis-a-vis the First Lien Secured Parties as set forth in this Agreement, (C) if any amount of such DIP Financing or cash collateral is applied to repay any of the First Lien Obligations, such amount is applied pursuant to Section 2.01, and (D) if any First Lien Secured Parties are granted adequate protection, including in the form of periodic payments, in connection with such DIP Financing or use of cash collateral, the proceeds of such adequate protection are applied pursuant to Section 2.01; provided that the First Lien Secured Parties of each Series shall have a right to object to the grant of a Lien to secure the DIP Financing over any Collateral subject to Liens in favor of the First Lien Secured Parties of such Series or its Authorized Representative that shall not constitute Shared Collateral; and provided, further, that the First Lien Secured Parties receiving adequate protection shall not object to any other First Lien Secured Party receiving adequate protection comparable to any adequate protection granted to such First Lien Secured Parties in connection with a DIP Financing or use of cash collateral.

SECTION 2.06 Reinstatement. In the event that any of the First Lien Obligations shall be paid in full and such payment or any part thereof shall subsequently, for whatever reason (including an order or judgment for disgorgement of a preference under the Bankruptcy Code, or any similar law, or the settlement of any claim in respect thereof), be required to be returned or repaid, the terms and conditions of this Article II shall be fully applicable thereto until all such First Lien Obligations shall again have been paid in full in cash.

SECTION 2.07 Insurance. As between the First Lien Secured Parties, the Collateral Agent, acting at the direction of the Applicable Authorized Representative, shall have the right to adjust or settle any insurance policy or claim covering or constituting Shared Collateral in the event of any loss thereunder and to approve any award granted in any condemnation or similar proceeding affecting the Shared Collateral.

SECTION 2.08 Refinancings. The First Lien Obligations of any Series may be Refinanced, in whole or in part, in each case, without notice to, or the consent (except to the extent a consent is otherwise required to permit the Refinancing transaction under any Secured Credit Document) of any First Lien Secured Party of any other Series, all without affecting the priorities provided for herein or the other provisions hereof; provided that the Authorized Representative of the holders of any such Refinancing indebtedness shall have executed a Joinder Agreement on behalf of the holders of such Refinancing indebtedness.

SECTION 2.09 Possessory Collateral Agent as Gratuitous Bailee for Perfection. (a) The Collateral Agent agrees to hold any Shared Collateral constituting Possessory Collateral that is part of the Collateral in its possession or control (or in the possession or control of its agents or bailees) as gratuitous bailee for the benefit of each other First Lien Secured Party and any assignee solely for the purpose of perfecting the security interest granted in such Possessory Collateral, if any, pursuant to the applicable First Lien Security Documents, in each case, subject to the terms and conditions of this Section 2.09. Pending delivery to the Collateral Agent, each other Authorized Representative agrees to hold any Shared Collateral constituting Possessory Collateral, from time to time in its possession, as gratuitous bailee for the benefit of each other First Lien Secured Party and any assignee, solely for the purpose of perfecting the security interest granted in such Possessory Collateral, if any, pursuant to the applicable First Lien Security Documents, in each case, subject to the terms and conditions of this Section 2.09.

(b) The duties or responsibilities of the Collateral Agent and each other Authorized Representative under this Section 2.09 shall be limited solely to holding any Shared Collateral constituting Possessory Collateral as gratuitous bailee for the benefit of each other First Lien Secured Party for purposes of perfecting the Lien held by such First Lien Secured Parties therein.

ARTICLE III

Existence and Amounts of Liens and Obligations

SECTION 3.01 Determinations with Respect to Amounts of Liens and Obligations. Whenever the Collateral Agent or any Authorized Representative shall be required, in connection with the exercise of its rights or the performance of its obligations hereunder, to determine the existence or amount of any First Lien Obligations of any Series, or the Shared Collateral subject to any Lien securing the First Lien Obligations of any Series, it may request that such information be furnished to it in writing by each other Authorized Representative and shall be entitled to make such determination on the basis of the information so furnished; provided, however, that if an Authorized Representative shall fail or refuse reasonably promptly to provide the requested information, the requesting Collateral Agent or Authorized Representative shall be entitled to make any such determination by such method as it may, in the exercise of its good faith judgment, determine, including by reliance upon a certificate of the Company. The Collateral Agent and each Authorized Representative may rely conclusively, and shall be fully protected in so relying, on any determination made by it in accordance with the provisions of the preceding sentence (or as otherwise directed by a court of competent jurisdiction) and shall have no liability to any Grantor, any First Lien Secured Party or any other person as a result of such determination.

ARTICLE IV

The Collateral Agent

SECTION 4.01 Appointment and Authority. (a) Each of the First Lien Secured Parties hereby irrevocably appoints Deutsche Bank Trust Company Americas to act on its behalf as the Collateral Agent hereunder and under each of the First Lien Security Documents and authorizes the Collateral Agent to take such actions on its behalf and to exercise such powers as are delegated to the Collateral Agent by the terms hereof or thereof, including for purposes of acquiring, holding and enforcing any and all Liens on Collateral granted by any Grantor to secure any of the First Lien Obligations, together with such powers and discretion as are reasonably incidental thereto. In this connection, the Collateral Agent and any co-agents, sub-agents and attorneys-in-fact appointed by the Collateral Agent pursuant to Section 4.05 for purposes of holding or enforcing any Lien on the Collateral (or any portion thereof) granted under any of the First Lien Security Documents, or for exercising any rights and remedies thereunder at the direction of the Applicable Authorized Representative, shall be entitled to the benefits of all provisions of this Article IV and Section 12 of the Credit Agreement and the equivalent provision of any Additional First Lien Agreement (as though such co-agents, sub-agents and attorneys-in-fact were the “Collateral Agent” named therein) as if set forth in full herein with respect thereto.

(b) Each Non-Controlling Secured Party acknowledges and agrees that the Collateral Agent shall be entitled, for the benefit of the First Lien Secured Parties, to sell, transfer or otherwise dispose of or deal with any Shared Collateral as provided herein and in the First Lien Security Documents, without regard to any rights to which the holders of the Non-Controlling Secured Obligations would otherwise be entitled as a result of such

Non-Controlling Secured Obligations. Without limiting the foregoing, each Non-Controlling Secured Party agrees that none of the Collateral Agent, the Applicable Authorized Representative or any other First Lien Secured Party shall have any duty or obligation first to marshal or realize upon any type of Shared Collateral (or any other Collateral securing any of the First Lien Obligations), or to sell, dispose of or otherwise liquidate all or any portion of such Shared Collateral (or any other Collateral securing any First Lien Obligations), in any manner that would maximize the return to the Non-Controlling Secured Parties, notwithstanding that the order and timing of any such realization, sale, disposition or liquidation may affect the amount of proceeds actually received by the Non-Controlling Secured Parties from such realization, sale, disposition or liquidation. Each of the First Lien Secured Parties waives any claim it may now or hereafter have against the Collateral Agent or the Authorized Representative of any other Series of First Lien Obligations or any other First Lien Secured Party of any other Series arising out of (i) any actions which the Collateral Agent, any Authorized Representative or any First Lien Secured Party takes or omits to take (including, actions with respect to the creation, perfection or continuation of Liens on any Collateral, actions with respect to the foreclosure upon, sale, release or depreciation of, or failure to realize upon, any of the Collateral and actions with respect to the collection of any claim for all or any part of the First Lien Obligations from any account debtor, guarantor or any other party) in accordance with the First Lien Security Documents or any other agreement related thereto or to the collection of the First Lien Obligations or the valuation, use, protection or release of any security for the First Lien Obligations, (ii) any election by any Applicable Authorized Representative or any holders of First Lien Obligations, in any proceeding instituted under the Bankruptcy Code, of the application of Section 1111(b) of the Bankruptcy Code or (iii) subject to Section 2.05, any borrowing by, or grant of a security interest or administrative expense priority under Section 364 of the Bankruptcy Code or any equivalent provision of any other Bankruptcy Law by, the Company or any of its Subsidiaries, as debtor-in-possession. Notwithstanding any other provision of this Agreement, the Collateral Agent shall not accept any Shared Collateral in full or partial satisfaction of any First Lien Obligations pursuant to Section 9-620 of the Uniform Commercial Code of any jurisdiction, without the consent of each Authorized Representative representing holders of First Lien Obligations for whom such Collateral constitutes Shared Collateral.

(c) Each Authorized Representative acknowledges and agrees that upon execution and delivery of a Joinder Agreement substantially in the form of Annex II by an additional Senior Class Debt Representative, the Collateral Agent and each Grantor in accordance with Section 5.13, the Collateral Agent will continue to act in its capacity as Collateral Agent in respect of the then existing Authorized Representatives and such additional Authorized Representative.

SECTION 4.02 Rights as a First Lien Secured Party. (a) The Person serving as the Collateral Agent hereunder shall have the same rights and powers in its capacity as a First Lien Secured Party under any Series of First Lien Obligations that it holds as any other First Lien Secured Party of such Series and may exercise the same as though it were not the Collateral Agent and the term “First Lien Secured Party” or “First Lien Secured Parties” or (as applicable) “Credit Agreement Secured Party”, “Credit Agreement Secured Parties”, “Initial Additional First Lien Secured Party”, “Initial Additional First Lien Secured Parties”, “Additional First Lien Secured Party” or “Additional First Lien Secured Parties” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Collateral

Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with the Company or any Subsidiary or other Affiliate thereof as if such Person were not the Collateral Agent hereunder and without any duty to account therefor to any other First Lien Secured Party.

SECTION 4.03 Exculpatory Provisions. (a) The Collateral Agent shall not have any duties or obligations except those expressly set forth herein and in the other First Lien Security Documents. Without limiting the generality of the foregoing, the Collateral Agent:

(i) shall not be subject to any fiduciary or other implied duties, regardless of whether an Event of Default has occurred and is continuing;

(ii) shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other First Lien Security Documents that the Collateral Agent is required to exercise as directed in writing by the Applicable Authorized Representative; provided that the Collateral Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Collateral Agent to liability or that is contrary to any First Lien Security Document or applicable law;

(iii) shall not, except as expressly set forth herein and in the other First Lien Security Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Company or any of its Affiliates that is communicated to or obtained by the Person serving as the Collateral Agent or any of its Affiliates in any capacity;

(iv) shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Applicable Authorized Representative or (ii) in the absence of its own gross negligence or willful misconduct or (iii) in reliance on a certificate of an authorized officer of the Company stating that such action is permitted by the terms of this Agreement. The Collateral Agent shall be deemed not to have knowledge of any Event of Default under any Series of First Lien Obligations unless and until notice describing such Event Default is given to the Collateral Agent by the Authorized Representative of such First Lien Obligations or the Company; and

(v) shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other First Lien Security Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any First Lien Security Document or any other agreement, instrument or document, or the creation, perfection or priority of any Lien purported to be created by the First Lien Security Documents, (v) the value or the sufficiency of any Collateral for any Series of First Lien Obligations, or (v) the satisfaction of any condition set forth in any Secured Credit Document, other than to confirm receipt of items expressly required to be delivered to the Collateral Agent.

(b) Each First Lien Secured Party acknowledges that, in addition to acting as the initial Collateral Agent, Deutsche Bank Trust Company Americas also serves as Administrative Agent under the Credit Agreement, and each First Lien Secured Party hereby waives any right to make any objection or claim against Deutsche Bank Trust Company Americas (or any successor Collateral Agent or any of their respective counsel) based on any alleged conflict of interest or breach of duties arising from the Collateral Agent also serving as the Administrative Agent.

SECTION 4.04 Reliance by Collateral Agent. The Collateral Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Collateral Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. The Collateral Agent may consult with legal counsel (who may be counsel for the Company), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

SECTION 4.05 Delegation of Duties. The Collateral Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any First Lien Security Document by or through any one or more sub-agents appointed by the Collateral Agent. The Collateral Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Affiliates. The exculpatory provisions of this Article shall apply to any such sub-agent and to the Affiliates of the Collateral Agent and any such sub-agent.

SECTION 4.06 Resignation of Collateral Agent. The Collateral Agent may at any time give notice of its resignation as Collateral Agent under this Agreement and the First Lien Security Documents to each Authorized Representative and the Company. Upon receipt of any such notice of resignation, the Applicable Authorized Representative shall have the right, with the consent of the Company (not to be unreasonably withheld or delayed; provided that no such consent shall be required if an Event of Default then exists and is continuing), to appoint a successor, which shall be a bank or trust company with an office in the United States, or an Affiliate of any such bank or trust company with an office in the United States. If no such successor shall have been so appointed by the Applicable Authorized Representative and shall have accepted such appointment within 30 days after the retiring Collateral Agent gives notice of its resignation, then the retiring Collateral Agent may, on behalf of the First Lien Secured Parties, appoint a successor Collateral Agent meeting the qualifications set forth above; provided that if the Collateral Agent shall notify the Company and each Authorized Representative that no qualifying Person has accepted such appointment, then such resignation shall nonetheless become effective in accordance with such notice and (a) the retiring Collateral Agent shall be discharged from its duties and obligations hereunder and under the First Lien Security

Documents (except that in the case of any collateral security held by the Collateral Agent on behalf of the First Lien Secured Parties under any of the First Lien Security Documents, the retiring Collateral Agent shall continue to hold such collateral security solely for purposes of maintaining the perfection of the security interests of the First Lien Secured Parties therein until such time as a successor Collateral Agent is appointed but with no obligation to take any further action at the request of the Applicable Authorized Representative or any other First Lien Secured Parties) and (b) all payments, communications and determinations provided to be made by, to or through the Collateral Agent shall instead be made by or to each Authorized Representative directly, until such time as the Applicable Authorized Representative appoints a successor Collateral Agent as provided for above in this Section. Upon the acceptance of a successor’s appointment as Collateral Agent hereunder and under the First Lien Security Documents, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring (or retired) Collateral Agent, and the retiring Collateral Agent shall be discharged from all of its duties and obligations hereunder or under the other First Lien Security Documents (if not already discharged therefrom as provided above in this Section). After the retiring Collateral Agent’s resignation hereunder and under the other Loan Documents, the provisions of this Article and Section 12 of the Credit Agreement and the equivalent provision of any Additional First Lien Agreement shall continue in effect for the benefit of such retiring Collateral Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Collateral Agent was acting as Collateral Agent. Upon any notice of resignation of the Collateral Agent hereunder and under the First Lien Security Documents, the Company agrees to use commercially reasonable efforts to transfer (and maintain the validity and priority of) the Liens in favor of the retiring Collateral Agent under the First Lien Security Documents to the successor Collateral Agent.

SECTION 4.07 Non-Reliance on Collateral Agent and Other First Lien Secured Parties. Each First Lien Secured Party acknowledges that it has, independently and without reliance upon the Collateral Agent, any Authorized Representative or any other First Lien Secured Party or any of their Affiliates and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and the other Secured Credit Documents. Each First Lien Secured Party also acknowledges that it will, independently and without reliance upon the Collateral Agent, any Authorized Representative or any other First Lien Secured Party or any of their Affiliates and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Secured Credit Document or any related agreement or any document furnished hereunder or thereunder.

SECTION 4.08 Collateral and Guaranty Matters. Each of the First Lien Secured Parties irrevocably authorizes the Collateral Agent, at its option and in its discretion:

(i) to release any Lien on any property granted to or held by the Collateral Agent under any First Lien Security Document in accordance with Section 2.04 or upon receipt of a written request from the Company stating that the releases of such Lien is permitted by the terms of each then extant Secured Credit Document; and

(ii) to release any Grantor from its obligations under the First Lien Security Documents upon receipt of a written request from the Company stating that such release is permitted by the terms of each then extant Secured Credit Document.

SECTION 5.07 Governing Law; Jurisdiction. This Agreement shall be construed in accordance with and governed by the law of the State of New York.

Nothing in this Agreement is intended to or shall impair the obligations of any Grantor, which are absolute and unconditional, to pay the First Lien Obligations as and when the same shall become due and payable in accordance with their terms.

SECTION 5.13 Additional Senior Debt. To the extent, but only to the extent permitted by the provisions of the Credit Agreement and the Additional First Lien Documents, the Company may incur Additional First Lien Obligations. Any such additional class or series of Additional First Lien Obligations (the “Senior Class Debt”) may be secured by a Lien on a senior basis, in each case under and pursuant to the First Lien Security Documents, if and subject to the condition that the Authorized Representative of any such Senior Class Debt (each, a “Senior Class Debt Representative”), acting on behalf of the holders of such Senior Class Debt (such Authorized Representative and holders in respect of any Senior Class Debt being referred to as the “Senior Class Debt Parties”), becomes a party to this Agreement by satisfying the conditions set forth in clauses (i) through (iv) of the immediately succeeding paragraph.

In order for a Senior Class Debt Representative to become a party to this Agreement,

(i) such Senior Class Debt Representative, the Collateral Agent and each Grantor shall have executed and delivered an instrument substantially in the form of Annex II (with such changes as may be reasonably approved by the Collateral Agent and such Senior Class Representative) pursuant to which such Senior Class Debt Representative becomes an Authorized Representative hereunder, and the Senior Class Debt in respect of which such Senior Class Debt Representative is the Representative and the related Senior Class Debt Parties become subject hereto and bound hereby;

(iv) the Additional First Lien Documents, as applicable, relating to such Senior Class Debt shall provide, in a manner reasonably satisfactory to the Collateral

Agent, that each Senior Class Debt Party with respect to such Senior Class Debt will be subject to and bound by the provisions of this Agreement in its capacity as a holder of such Senior Class Debt.

SECTION 5.14 Integration.
