(b) It is acknowledged that the Obligations of any Series may, subject to any limitations set forth in the Credit Documents of the other Series, be 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 Secured Parties of each Series.

(c) Notwithstanding the date, time, method, manner or order of grant, attachment or perfection of any Liens securing any Series of 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 Credit Documents or any defect or deficiencies in the Liens securing the Obligations of any Series or any other circumstance whatsoever (but, in each case, subject to Sections 1.03 and 2.01(d)), each Secured Party hereby agrees that the Liens securing each Series of Obligations on any Shared Collateral shall be of equal priority.

(d) If either the Bank Obligations or the Notes Obligations are subject to Impairment with respect to any Shared Collateral and the other such Series is not subject to the same Impairment, the Collateral Agent shall allocate the Proceeds of any such Shared Collateral to all Series of Obligations in accordance with Section 2.01(a), disregarding the existence of such Impairment.

(e) Notwithstanding anything in this Agreement or any other Security Document to the contrary, Collateral consisting of cash and cash equivalents pledged to secure Bank 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 2.12(a), 2.22(a) or 2.22(j) of the Credit Agreement (or any equivalent successor provision) shall be applied as specified in such Section of the Credit Agreement and will not constitute Shared Collateral.

SECTION 2.02. Actions With Respect to Shared Collateral; Prohibition on Contesting Liens. (a) With respect to any Shared Collateral, (i) only the Collateral Agent shall act or refrain from acting with respect to the Shared Collateral, and then only on the instructions of the Applicable Authorized Representative pursuant to Section 2.10, (ii) the Collateral Agent shall not follow any instructions with respect to such Shared Collateral from any Secured Party other than the Applicable Authorized Representative and (iii) no Secured Party (other than the Applicable Authorized Representative) shall, or shall instruct the Collateral Agent to, commence any judicial or nonjudicial foreclosure proceedings with respect to, seek to have a trustee, receiver, liquidator or similar official appointed for or over, attempt any action to take possession of, exercise any right, remedy or power with respect to, or otherwise take any action to enforce its security interest in or realize upon, or take any other action available to it in respect of, any Shared Collateral, whether under any 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 Security Documents, shall be entitled to take any such actions or exercise any such remedies with respect to Shared Collateral; provided that, notwithstanding the foregoing, (i) in any Insolvency or Liquidation Proceeding, the Collateral Agent or any other Secured Party may file a proof of claim or statement of interest with respect to the Obligations owed to Secured Parties; (ii) the Collateral Agent or any other Secured Party may take any action to preserve or protect the validity and enforceability of the Liens granted in favor of Secured Parties, provided that no such action is, or could reasonably be expected to be, (A) adverse to the Liens granted in favor of the other Secured Parties or the rights of the Collateral Agent or any other Secured Parties to exercise remedies in respect thereof or (B) otherwise inconsistent with the terms of this Agreement, including the automatic release of the Liens provided in Section 2.04; and (iii) the Collateral Agent or any other Secured Party may file any responsive or defensive pleadings in opposition to any motion, claim, adversary proceeding or other pleading made by any person objecting to or otherwise seeking the disallowance of the claims of such Secured Party, including any claims secured by the Shared Collateral, in each case, to the extent not inconsistent with the terms of this Agreement. 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 other Secured Party will contest, protest or object to any foreclosure proceeding or action brought by the Collateral Agent or any other exercise by the Collateral Agent of any rights and remedies relating to the Shared Collateral. The foregoing shall not be construed to limit the rights and priorities of any Secured Party, Collateral Agent or 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 Obligations (other than funds deposited for the discharge or defeasance of any Notes Obligations) other than pursuant to the Security Documents or as contemplated by Section 2.01(e), and by executing this Agreement or an Additional Authorized Representative Joinder Agreement, each Authorized Representative and the Series of Secured Parties for which it is acting hereunder agree to be bound by the provisions of this Agreement and the other Security Documents applicable to it.

(c) Each of the Secured Parties agrees that it will not (and hereby waives any right to) contest or support any other person in contesting, in any proceeding (including any Insolvency or Liquidation Proceeding), the perfection, priority, validity or enforceability of a Lien held by or on behalf of any of the Secured Parties in all or any part of the Collateral, or the provisions of this Agreement.

SECTION 2.03. No Interference; Payment Over; No New Liens. (a) Each Secured Party agrees that (i) it will not challenge or question in any proceeding the validity or enforceability of any Obligations of any Series or any Security Document or the validity, attachment, perfection or priority of any Lien under any 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 Secured Party to exercise any right, remedy or power with respect to any Shared Collateral or (B) consent to the exercise by the Collateral Agent or any other 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 Insolvency or Litigation Proceeding or other proceeding any claim against the Collateral Agent or any other 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 Secured Party shall be liable for any action taken or omitted to be taken by the Collateral Agent, such Applicable Authorized Representative or other 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 Secured Party to enforce this Agreement in accordance with its terms.

(b) Each 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 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, at any time prior to the Discharge of each of the Obligations, then it shall hold such Shared Collateral, proceeds or payment in trust for the other 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 hereof.

(c) The parties hereto agree that, so long as the Discharge of all the Obligations has not occurred, none of the Grantors shall, or shall permit any of their respective subsidiaries to, grant or permit any additional Liens on any asset to secure any Additional Obligation in favor of a particular Series after the date hereof unless it has granted, or concurrently therewith grants, a Lien on such asset to secure the Obligations in favor of all other Series. To the extent that the provisions of the immediately preceding sentence are not complied with for any reason, without limiting any other right or remedy available to the Collateral Agent or the other Secured Parties, the Collateral Agent agrees, for itself and on behalf of the other Secured Parties, that any amounts received by or distributed to any Secured Party pursuant to or as a result of any Lien granted in contravention of this Section 2.03(c) shall be subject to Section 2.03(b).

SECTION 2.04. Automatic Release of Liens; Amendments to Security Documents. (a) If at any time the Collateral Agent forecloses upon or otherwise exercises rights, remedies and powers against any Shared Collateral, and in connection therewith determines to release any Liens over such Shared Collateral, 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 Secured Parties on 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 hereof.

(b) Each 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 Security Document, so long as the Collateral Agent receives a certificate of the Company, in form and substance satisfactory to the Collateral Agent, stating that such amendment is permitted by the terms of each then extant Credit Document. Additionally, each 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 Security Document solely as such Security Document relates to a particular Series of Obligations so long as (x) such amendment is in accordance with the Credit Document pursuant to which such Series of Obligations was incurred and (y) such amendment does not adversely affect the Secured Parties of any other Series.

(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 Security Document provided for in this Section.

SECTION 2.05. Certain Agreements With Respect to Bankruptcy or Insolvency Proceedings. (a) This Agreement shall continue in full force and effect notwithstanding the commencement of any proceeding under any Bankruptcy Law by or against any Grantor or any of its subsidiaries. If, in any Insolvency or Liquidation Proceeding, debt obligations of the reorganized debtor secured by Liens upon any property of the reorganized debtor are distributed, pursuant to a plan of reorganization or similar dispositive restructuring plan, on account of each Series of Obligations, then, to the extent the debt obligations distributed on account of each Series of Obligations are secured by Liens upon the same assets or property, the provisions of this Agreement will survive the distribution of such debt obligations pursuant to such plan and will apply with like effect to the Liens securing such debt obligations.

(b) If, prior to the Discharge of Bank Obligations, any Grantor shall become subject to a case (a “Bankruptcy Case”) under the Bankruptcy Code or any other Bankruptcy Law 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 similar provision of foreign law or the use of cash collateral under Section 363 of the Bankruptcy Code or any similar provision of foreign law, each 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 the Authorized Representative of the Bank Obligations 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 Secured Parties that are DIP Lenders, each other Secured Party will subordinate its Liens with respect to such Shared Collateral on the same terms as the Liens of the Secured Parties that are DIP Lenders (other than any Liens of any 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 Obligations of the Secured Parties that are DIP Lenders, each other Secured Party will confirm the priorities with respect to such Shared Collateral as set forth herein), in each case so long as (A) the 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 Secured Parties (other than any Liens of the Secured Parties constituting DIP Financing Liens) as existed prior to the commencement of the Bankruptcy Case, (B) the Secured Parties of each Series are granted Liens on any additional collateral pledged to any 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 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 Obligations, such amount is

applied pursuant to Section 2.01 of this Agreement and (D) if any 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 of this Agreement; provided that the 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 Secured Parties of such Series or its Authorized Representative that shall not constitute Shared Collateral; and provided, further, that the Secured Parties receiving adequate protection shall not object to any other Secured Party receiving adequate protection comparable to any adequate protection granted to such Secured Parties in connection with a DIP Financing or use of cash collateral.

SECTION 2.06. Reinstatement. In the event that any of the 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 Title 11 of the United Stated 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 Obligations shall again have been paid in full in cash.

SECTION 2.07. Insurance. As between the Secured Parties, to the extent of its interest under the Security Documents, 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 and the Collateral Agent shall apply the proceeds received from any such adjustment, settlement or award in accordance with the provisions of Section 2.01.

SECTION 2.08. Refinancings. The 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 Credit Document) of any 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 an Additional Authorized Representative Joinder Agreement on behalf of the holders of such Refinancing indebtedness, which Additional Authorized Representative Joinder Agreement shall be entered into by the Company, the Administrative Agent and the Trustee and Collateral Agent.

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 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 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 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 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 Secured Party for purposes of perfecting the Lien held by such Secured Parties therein.

SECTION 2.10. Enforcement by the Collateral Agent. (a) If any Event of Default under any Credit Document shall have occurred and be continuing, the Collateral Agent shall act in relation to the Collateral in accordance with the instructions of the Applicable Authorized Representative (acting pursuant to the terms of the applicable Credit Document).

(b) The Collateral Agent may disregard any instructions from any other person to exercise any right or remedy hereunder with respect to the Collateral if those instructions are inconsistent with this Agreement.

(c) Any person entitled to instruct the Collateral Agent to exercise any right or remedy hereunder with respect to the Collateral may give or refrain from giving instructions to the Collateral Agent to exercise or refrain from exercising any right or remedy hereunder with respect to the Collateral as it sees fit in accordance with the other provisions of this Agreement.

(d) The Collateral Agent shall inform in writing each other Authorized Representative on receiving any instructions under this Section 2.10 to enforce any right, remedy or power with respect to the Shared Collateral.

ARTICLE III

Existence and 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 Obligations of any Series, or the Shared Collateral subject to any Lien securing the 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 any 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 Secured Party or any other person as a result of such determination.

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 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 (as though such co-agents, sub-agents and attorneys-in-fact were the “Collateral Agent” under the Security Documents) as if set forth in full herein with respect thereto.

(b) Each Secured Party acknowledges and agrees that, upon the occurrence of an Event of Default under the Security Documents and during the continuation thereof, the Collateral Agent shall be entitled, for the benefit of the Secured Parties, to sell, transfer or otherwise dispose of or deal with any Shared Collateral as provided herein and in the Security Documents, without regard to any rights to which the holders of the Obligations would otherwise be entitled as a result of such Obligations. Without limiting the foregoing, each Secured Party agrees that none of the Collateral Agent, the Applicable Authorized Representative or any other 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 Obligations), or to sell, dispose of or otherwise liquidate all or any portion of such Shared Collateral (or any other Collateral securing any Obligations), in any manner that would maximize the return to such Secured Party or any Series of 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 such Secured Party from such realization, sale, disposition or liquidation. Each of the Secured Parties waives any claim it may now or hereafter have against the Collateral Agent or the Authorized Representative of any other Series of Obligations or any other Secured Party of any other Series arising out of (i) any actions which the Collateral Agent, any Authorized Representative or any Secured Party takes or omits to

(iii) shall not, except as expressly set forth herein and in the other Security Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to a Grantor or any of its Affiliates that is

(iv) shall not be liable for any action taken or not taken by it (1) with the consent or at the request of the Applicable Authorized Representative or (2) in the absence of its own gross negligence or willful misconduct or (3) in reliance on a certificate of an authorized officer of the Company stating that such action is permitted by the terms of this Agreement or the Security Documents. The Collateral Agent shall be deemed not to have knowledge of any Event of Default under any Series of Obligations unless and until written notice describing such Event of Default is given to the Collateral Agent by the Authorized Representative of such Obligations or a Grantor; and

(v) shall not be responsible for or have any duty to ascertain or inquire into (1) any statement, warranty or representation made in or in connection with this Agreement (except for its representations and warranties set forth in Article V) or any other Security Document, (2) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (3) 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 or Event of Default, (4) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Security Document or any other agreement, instrument or document, or the creation, perfection or priority of any Lien purported to be created by the Security Documents, (5) the value or the sufficiency of any Collateral for any Series of Obligations or (6) the satisfaction of any condition set forth in any Credit Document, other than to confirm receipt of items expressly required to be delivered to the Collateral 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. The Collateral Agent may at any time solicit written confirmatory instructions, in the form of an officers’ certificate of the Company or an order of a court of competent jurisdiction, as to any action that it may be requested or required to take, or that it may propose to take, in the performance of any of its obligations under this Agreement or the Security Documents. The Collateral Agent will be entitled to require that all agreements, certificates, opinions, instruments and other documents at any time submitted to it, including those expressly provided for in this Agreement or the Security Documents, be delivered to it in a form and with substantive provisions reasonably satisfactory to it.

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 other 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 its 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. Termination and Resignation of Collateral Agent. The Collateral Agent may at any time give notice of its resignation as Collateral Agent under this Agreement and the other 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, in consultation with the Company, to appoint a successor, which shall be a bank with an office in the United States, or an Affiliate of any such bank 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 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 other Security Documents (except that in the case of any collateral security held by the Collateral Agent on behalf of the Secured Parties under any of the 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 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 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 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 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 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 other 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 Security Documents to the successor Collateral Agent.

SECTION 4.07. Non-Reliance on Collateral Agent and other Secured Parties. Each Secured Party acknowledges that it has, independently and without reliance upon the Collateral Agent, any Authorized Representative or any other 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 Credit Documents. Each Secured Party also acknowledges that it will, independently and without reliance upon the Collateral Agent, any Authorized Representative or any other 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 Credit Document or any related agreement or any document furnished hereunder or thereunder.

(b) Each Grantor will upon demand pay to the Collateral Agent and the Agents the amount of any and all out-of-pocket expenses, including the fees and expenses of its counsel and of any experts and agents, that they may incur in connection with (i) the administration of this Agreement, or (ii) the custody, preservation, use or operation

SECTION 5.02. Waivers; Amendment. (a) No failure or delay on the part of any party hereto in exercising any right or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power.

Additional Obligations does not violate the terms of the Credit Documents then outstanding and (D) specifying the name and address of the authorized representative for such Indebtedness and other obligations (the “Additional Authorized Representative”) and (ii) a completed and fully executed Additional Authorized Representative Joinder Agreement. Upon the delivery of such certificate and the related attachments as provided herein, the obligations designated in such certificate as “Additional Obligations” shall become Additional Obligations for all purposes of this Agreement. Each Additional Authorized Representative agrees that upon the satisfaction of all conditions set forth in the preceding sentence, the Collateral Agent shall act hereunder for the benefit of all Secured Parties, including any Secured Parties that hold any Additional Obligations, and each Additional Authorized Representative agrees to the appointment, and acceptance of the appointment, of the Collateral Agent as agent for the holders of such Additional Obligations as set forth in each Additional Authorized Representative Joinder Agreement and agrees, on behalf of itself and each Secured Party it represents, to be bound by this Agreement.

(a) any lack of validity or enforceability of any Credit Document;

(b) any change in the time, place or manner of payment of, or in any other term of (including the Refinancing of), all or any portion of the Obligations, it being specifically acknowledged that a portion of the Obligations consists or may consist of Indebtedness that is revolving in nature, and the amount thereof that may be outstanding

at any time or from time to time may be increased or reduced and subsequently reborrowed;
