(a) Each Junior Secured Obligations Secured Party agrees that (i) it will not take or cause to be taken any action the purpose or effect of which is, or could be, to make any Junior Lien pari passu with, or to give such Junior Secured Obligations Secured Party any preference or priority relative to, any Senior Lien with respect to the Collateral subject to such Senior Lien and Junior Lien or any part thereof, (ii) it will not challenge or question in any proceeding the validity or enforceability of any Senior Secured Obligations or Senior Secured Obligations Security Document, or the validity, attachment, perfection or priority of any Senior Lien, or the validity or enforceability of the priorities, rights or duties established by or other provisions of this Agreement, (iii) 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 Collateral subject to any Junior Lien by any Senior Secured Obligations Secured Parties secured by Senior Liens on such Collateral or any Senior Representative acting on their behalf, (iv) it shall have no right to (A) direct any Senior Representative or any holder of Senior Secured Obligations to exercise any right, remedy or power with respect to the Collateral subject to any Junior Lien or (B) consent to the exercise by any Senior Representative or any other Senior Secured Obligations Secured Party of any right, remedy or power with respect to the Collateral subject to any Junior Lien, (v) it will not institute any suit or assert in any suit or Insolvency or Liquidation Proceeding any claim against any Senior Representative or other Senior Secured Obligations Secured Party seeking damages from or other relief by way of specific performance, instructions or otherwise with respect to, and neither any Senior Representative nor any other Senior Secured Obligations Secured Party shall be liable to any Junior Secured Obligations Secured Party for, any action taken or omitted to be taken by such Senior Representative or other Senior Secured Obligations Secured Party with respect to any Collateral securing such Senior Secured Obligations that is subject to any Junior Lien, (vi) it will not seek, and hereby waives any right, to have any Senior Secured Obligations Collateral subject to any Junior Lien or any part thereof marshaled upon any foreclosure or other disposition of such Collateral and (vii) it will not attempt, directly or indirectly, whether by judicial proceedings or otherwise, to challenge the enforceability of any provision of this Agreement.

(b) The Junior Representative and each other Junior Secured Obligations Secured Party hereby agrees that until the associated Discharge of Senior Secured Debt Obligations, if it shall obtain possession of any Senior Secured Obligations Collateral or shall realize any proceeds or payment in respect of any such Collateral, pursuant to remedies taken under any Junior Secured Obligations 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 associated Discharge of Senior Secured Debt Obligations secured, or intended to be secured, by such Collateral, then it shall hold such Collateral, proceeds or payment in trust for the applicable Senior Secured Obligations Secured Parties and transfer such

Collateral, proceeds or payment, as the case may be, to the Senior Representative reasonably promptly after obtaining actual knowledge or notice from the Senior Secured Obligations Secured Parties that it has possession of such Senior Secured Obligations Collateral or proceeds or payments in respect thereof. Each Junior Secured Obligations Secured Party agrees that if, at any time, it obtains actual knowledge or receives notice that all or part of any payment with respect to any Senior Secured Obligations previously made shall be rescinded for any reason whatsoever, such Junior Secured Obligations Secured Party shall promptly pay over to the Senior Representative any payment received by it and then in its possession or under its control in respect of any Collateral subject to any Senior Lien securing such Senior Secured Obligations and shall promptly turn any Collateral subject to any such Senior Lien then held by it over to the Senior Representative, and the provisions set forth in this Agreement shall be reinstated as if such payment had not been made, until the payment and satisfaction in full of the Senior Secured Obligations. All Junior Liens will remain attached to and enforceable against all proceeds so held or remitted. Anything contained herein to the contrary notwithstanding, this Section 2.04(b) shall not apply to any proceeds of Senior Secured Obligations Collateral realized in a transaction not prohibited by the Senior Documents and as to which the possession or receipt thereof by the Junior Representative or other Junior Secured Obligations Secured Party is otherwise permitted by the Senior Documents.

SECTION 2.05. Release of Liens; Automatic Release of Junior Liens. (a) The Junior Representative and each other Junior Secured Obligations Secured Party agree that (i) in the event the Senior Secured Obligations Secured Parties release their Lien on any Senior Secured Obligations Collateral subject to any Junior Lien pursuant to the terms contained in this Agreement (other than a release in connection with a sale, transfer or other disposition of Senior Secured Obligations Collateral, which shall be governed by clause (a)(ii) below), such Junior Lien on such Collateral shall terminate and be released automatically and without further action unless, at the time of such release by the Senior Secured Obligations Secured Parties, an Event of Default shall then have occurred and be continuing under the Junior Documents (provided that any Junior Lien that would have otherwise been released and terminated pursuant to this clause (a)(i) in the absence of such an Event of Default under the Junior Documents shall terminate and be released automatically and without further action when such Event of Default (and all other Events of Default under the Junior Documents) cease to exist); and (ii) in the event of a sale, transfer or other disposition of Senior Secured Obligations Collateral subject to any Junior Lien (regardless of whether or not an Event of Default has occurred and is continuing under the Junior Documents at the time of such sale, transfer or other disposition), such Junior Lien on such Collateral shall terminate and be released automatically and without further action if the applicable Senior Liens on such Collateral are released and if such sale, transfer or other disposition either (A) is then not prohibited by the Junior Documents or (B) occurs in connection with the foreclosure upon or other exercise of rights and remedies with respect to such Senior Secured Obligations Collateral; provided that such Junior Lien shall remain in place with respect to any proceeds of a sale, transfer or other disposition under this clause (a)(ii) that remain after the associated Discharge of Senior Secured Debt Obligations. In addition, for the avoidance of doubt, the Junior Representative and each Junior Secured Obligations Secured Party agree that, with respect to any property or assets that would otherwise

constitute Senior Secured Obligations Collateral, the requirement that a Junior Lien attach to, or be perfected with respect to, such property or assets shall be waived automatically and without further action so long as the requirement that a Senior Lien attach to, or be perfected with respect to, such property or assets is waived by the Senior Secured Obligations Secured Parties (or the Senior Representative) in accordance with the Senior Documents and so long as no Event of Default under the Junior Documents shall have occurred, be continuing or would result therefrom at such time. Notwithstanding the foregoing, in the event of release of Liens by the Senior Secured Obligations Secured Parties on all or substantially all of the Senior Secured Obligations Collateral (other than when such release occurs in connection with the Senior Secured Obligations Secured Parties’ foreclosure upon or other exercise of rights and remedies with respect to such Collateral), no release of the Junior Lien on such Senior Secured Obligations Collateral under this Section 2.05 shall be made (it being understood that this Section 2.05 shall not affect any other obligation of the Junior Secured Obligations Secured Parties to any other Person, including a Loan Party, to release Liens pursuant to the Junior Documents or the Junior Secured Obligations Security Documents or otherwise) unless (A) consent to the release of such Junior Liens has been given by the requisite percentage or number of the Junior Secured Obligations Secured Parties at the time outstanding as provided for in the applicable Junior Documents and (B) Holdings has delivered an Officers’ Certificate to the Revolving Facility Agent and the Term Facility Agent certifying that all such consents have been obtained.

(b) The Revolving Facility Agent and the Term Facility Agent agree for the benefit of Holdings and the other Grantors that, with respect to the release of any Collateral, if the Revolving Facility Agent or Term Facility Agent, as applicable, at any time receives:

(i) an Officers’ Certificate stating that (A) the signing officers have read Article 2 of this Agreement and understand the provisions and the definitions relating hereto, (B) such officers have made such examination or investigation as is necessary to enable such Persons to express an informed opinion as to whether or not the conditions precedent in this Agreement and all other Secured Documents, if any, relating to the release of such Collateral have been complied with and (C) in the opinion of such officers, such conditions precedent, if any, have been complied with;

(ii) the proposed instrument or instruments releasing such Lien as to such property in recordable form, if applicable; and

(iii) prior to the associated Discharge of Senior Secured Debt Obligations, the written confirmation of the applicable Senior Representative (or, at any time after the associated Discharge of Senior Secured Debt Obligations, the Junior Representative) (such confirmation to be given following receipt of, and based solely on, the Officers’ Certificate described in clause (i) above) that, in its view, such release is permitted by Section 2.05(a) and the respective Secured Documents governing the Revolving Facility Obligations or the Term Facility Obligations, as applicable, the holders of which such Representative represents;

then the Revolving Facility Agent or Term Facility Agent, as applicable, will execute (with such acknowledgements and/or notarizations as are required) and deliver such release to Holdings or other applicable Grantor on or before the later of (x) the date specified in such request for such release and (y) the second business day after the date of receipt of the items required by this Section 2.05(b) by the applicable Representative.

(c) The Junior Representative agrees to execute and deliver (at the sole cost and expense of the Grantors) all such releases and other instruments as shall reasonably be requested by the Senior Representative to evidence and confirm any release of Junior Secured Obligations Collateral provided for in this Section 2.05.

SECTION 2.06. Certain Agreements With Respect to Insolvency or Liquidation Proceedings. (a) This Agreement shall continue in full force and effect, notwithstanding the commencement of any Insolvency or Liquidation Proceeding by or against Holdings or any Restricted Subsidiaries.

(b) Other than with respect to the Chapter 11 Cases (as defined in the Revolving Facility Credit Agreement), if Holdings or any of its Restricted Subsidiaries shall become subject to a 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 the use of cash collateral under Section 363 of the Bankruptcy Code, each Junior Secured Obligations Secured Party agrees that it will raise no objection, and will waive any claim such Person may now or hereafter have, to any such financing or to the Liens on the Senior Secured Obligations Collateral securing the same (“DIP Financing Liens”), or to any use of cash collateral that constitutes Senior Secured Obligations Collateral or to any grant of administrative expense priority under Section 364 of the Bankruptcy Code, unless (i) the Senior Secured Obligations Secured Parties, or a representative authorized by the Senior Secured Obligations Secured Parties, shall then oppose or object to such DIP Financing or such DIP Financing Liens or such use of cash collateral or (ii) such DIP Financing Liens are neither senior to, nor rank pari passu with, the Senior Liens upon any property of the estate in such Insolvency or Liquidation Proceeding. To the extent such DIP Financing Liens are senior to, or rank pari passu with, the Senior Liens, the Junior Representative will, for itself and on behalf of the other Junior Secured Obligations Secured Parties, subordinate the Junior Liens on the Senior Secured Obligations Collateral to the Senior Liens and the DIP Financing Liens, so long as the Junior Secured Obligations Secured Parties retain Liens on all the Junior Secured Obligations Collateral, including proceeds thereof arising after the commencement of any Insolvency or Liquidation Proceeding, with the same priority relative to the Senior Secured Obligations Collateral as existed prior to the commencement of the case under the Bankruptcy Code.

(c) Each Junior Secured Obligations Secured Party agrees that it will not object to or oppose a sale or other disposition of any Senior Secured Obligations Collateral (or any portion thereof) under Section 363 of the Bankruptcy Code or any other provision of the Bankruptcy Code if the Senior Secured Obligations Secured Parties shall have consented to such sale or disposition of such Senior Secured Obligations Collateral and all Senior Liens and Junior Liens will attach to the proceeds of the sale.

(d) The holders of Junior Secured Obligations and the Junior Representative will not file or prosecute in any Insolvency or Liquidation Proceeding any motion for adequate protection (or any comparable request for relief) based upon their interest in the Collateral under the Junior Liens, and will not object to or contest (i) any request by the Senior Representative or the holders of Senior Secured Obligations for adequate protection or (ii) any objection by the Senior Representative or the holders of Senior Secured Obligations to any motion, relief, action or proceeding based on the Senior Representative or holders of the Senior Secured Obligations claiming a lack of adequate protection, except that the holders of Junior Secured Obligations and the Junior Representative may:

(i) freely seek and obtain relief granting a Junior Lien co-extensive in all respects with, but subordinated (as set forth in Section 2.01) to, all Liens granted in the Insolvency or Liquidation Proceeding to, or for the benefit of, the holders of Senior Secured Obligations;

(ii) freely vote on any plan of reorganization or similar dispositive restructuring plan; and

(iii) freely seek and obtain any relief upon a motion for adequate protection (or any comparable relief), without any condition or restriction whatsoever, at any time after the associated Discharge of Senior Secured Debt Obligations.

(e) Each of the Junior Secured Obligations Secured Parties waives any claim such Junior Secured Obligations Secured Party may now or hereafter have against the Senior Representative or any other Senior Secured Obligations Secured Party (or their representatives) arising out of any election by the Senior Representative or any Senior Secured Obligations Secured Parties, in any proceeding instituted under the Bankruptcy Code, of the application of Section 1111(b) of the Bankruptcy Code.

SECTION 2.07. Reinstatement. In the event that any of the Senior Secured 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 Senior Secured Obligations shall again have been paid in full in cash.

SECTION 2.08. Entry Upon Premises by the Revolving Facility Agent and the Revolving Facility Secured Parties. (a) If the Revolving Facility Agent takes any enforcement action with respect to the Revolving Facility First Lien Collateral, the Term Facility Secured Parties (i) shall reasonably cooperate with the Revolving Facility Agent (at the sole cost and expense of the Revolving Facility Agent (it being understood nothing in this Section 2.08 affects any Grantor’s reimbursement or indemnity obligations under

any Secured Document) and subject to the condition that the Term Facility Secured Parties shall have no obligation or duty to take any action or refrain from taking any action that could reasonably be expected to result in the incurrence of any liability or damage to the Term Facility Secured Parties) in its efforts to enforce its security interest in the Revolving Facility First Lien Collateral and to finish any work-in-process and assemble the Revolving Facility First Lien Collateral, (ii) shall not take any action designed or intended to hinder or restrict in any respect the Revolving Facility Agent from enforcing its security interest in the Revolving Facility First Lien Collateral or from finishing any work-in-process or assembling the Revolving Facility First Lien Collateral, and (iii) subject to the rights of any landlords under real estate leases, shall permit the Revolving Facility Agent, its employees, agents, advisers and representatives, at the sole cost and expense of the Revolving Facility Secured Parties (it being understood nothing in this Section 2.08 affects any Grantor’s reimbursement or indemnity obligations under any Secured Document) and upon reasonable advance notice, to enter upon and use the Term Facility First Lien Collateral (including (A) equipment, processors, computers and other machinery related to the storage or processing of records, documents or files and (B) intellectual property (in connection with which the Term Facility Agent and the Term Facility Secured Parties shall grant a nonexclusive right to use and license and sublicense Term Facility Collateral consisting of intellectual property to enable the Revolving Facility Agent to assemble, prepare for sale, advertise, market and dispose of the Revolving Facility Collateral, it being understood that such right will not impose additional obligations on the Grantors, and will be solely as between the relevant creditors)), for a period not to exceed 180 days after the taking of such enforcement action, for purposes of (1) assembling and storing the Revolving Facility First Lien Collateral and completing the processing of and turning into finished goods of any Revolving Facility First Lien Collateral consisting of work-in-process, (2) selling any or all of the Revolving Facility First Lien Collateral located on such Term Facility First Lien Collateral, whether in bulk, in lots or to customers in the ordinary course of business or otherwise, (3) removing any or all of the Revolving Facility First Lien Collateral located on such Term Facility First Lien Collateral, or (4) taking reasonable actions to protect, secure and otherwise enforce the rights of the Revolving Facility Secured Parties in and to the Revolving Facility First Lien Collateral; provided, however, that nothing contained in this Agreement shall restrict the rights of the Term Facility Agent from selling, assigning or otherwise transferring any Term Facility First Lien Collateral prior to the expiration of such 180-day period if the purchaser, assignee or transferee thereof agrees to be bound by the provisions of this Section. If any stay or other order prohibiting the exercise of remedies with respect to the Revolving Facility First Lien Collateral has been entered by a court of competent jurisdiction, such 180-day period shall be tolled during the pendency of any such stay or other order. If the Revolving Facility Agent conducts a public auction or private sale of the Revolving Facility First Lien Collateral at any of the real property included within the Term Facility First Lien Collateral, the Revolving Facility Agent shall provide the Term Facility Agent with reasonable notice and use reasonable efforts to hold such auction or sale in a manner which would not unduly disrupt the Term Facility Agent’s use of such real property.

(b) During the period of actual occupation, use or control by the Revolving Facility Secured Parties or their agents or representatives of any Term Facility

First Lien Collateral, the Revolving Facility Secured Parties shall (i) be responsible for the ordinary course third-party expenses related thereto, including costs with respect to heat, light, electricity, water and real property taxes with respect to that portion of any premises so used or occupied, and (ii) be obligated to repair at their expense any physical damage to such Term Facility First Lien Collateral or other assets or property resulting from such occupancy, use or control, and to leave such Term Facility First Lien Collateral or other assets or property in substantially the same condition as it was at the commencement of such occupancy, use or control, ordinary wear and tear excepted. The Revolving Facility Secured Parties jointly and severally agree to pay, indemnify and hold the Term Facility Agent and its officers, directors, employees and agents harmless from and against any liability, cost, expense, loss or damages, including legal fees and expenses, resulting from the gross negligence or willful misconduct of the Revolving Facility Agent or any of its agents, representatives or invitees in its or their operation of such facilities. In the event, and only in the event, that in connection with its use of some or all of the premises constituting Term Facility First Lien Collateral, the Revolving Facility Agent requires the services of any employees of Holdings or any of their Subsidiaries, the Revolving Facility Agent shall pay directly to any such employees the appropriate, allocated wages of such employees, if any, during the time periods that the Revolving Facility Agent requires their services. Notwithstanding the foregoing, in no event shall the Revolving Facility Secured Parties have any liability to the Term Facility Secured Parties pursuant to this Section as a result of any condition (including any environmental condition, claim or liability) on or with respect to the Term Facility First Lien Collateral existing prior to the date of the exercise by the Revolving Facility Secured Parties of their rights under this Section and the Revolving Facility Secured Parties shall have no duty or liability to maintain the Term Facility First Lien Collateral in a condition or manner better than that in which it was maintained prior to the use thereof by the Revolving Facility Secured Parties, or for any diminution in the value of the Term Facility First Lien Collateral that results solely from ordinary wear and tear resulting from the use of the Term Facility First Lien Collateral by the Revolving Facility Secured Parties in the manner and for the time periods specified under this Section 2.08. Without limiting the rights granted in this paragraph, the Revolving Facility Agent, to the extent that rights have been exercised under this Section 2.08 by the Revolving Facility Agent, shall cooperate with the Term Facility Secured Parties in connection with any efforts made by the Term Facility Secured Parties to sell the Term Facility First Lien Collateral.

SECTION 2.09. Insurance. Unless and until written notice by the Revolving Facility Agent to the Term Facility Agent that the Discharge of Senior Secured Debt Obligations in respect of the Revolving Facility Obligations has occurred, as between the Revolving Facility Agent, on the one hand, and the Term Facility Agent, on the other hand, only the Revolving Facility Agent will have the right (subject to the rights of the Grantors under the Revolving Facility Debt Documents and the Term Facility Debt Documents) to adjust or settle any insurance policy or claim covering or constituting Revolving Facility First Lien Collateral in the event of any loss thereunder and to approve any award granted in any condemnation or similar proceeding affecting the Revolving Facility First Lien Collateral. Unless and until written notice by the Term Facility Agent to the Revolving Facility Agent that the Discharge of Senior Secured Debt

Obligations in respect of the Term Facility Obligations has occurred, as between the Revolving Facility Agent, on the one hand, and the Term Facility Agent, on the other hand, only the Term Facility Agent will have the right (subject to the rights of the Grantors under the Revolving Facility Debt Documents and the Term Facility Debt Documents) to adjust or settle any insurance policy covering or constituting Term Facility First Lien Collateral in the event of any loss thereunder and to approve any award granted in any condemnation or similar proceeding solely affecting the Term Facility First Lien Collateral. To the extent that an insured loss covers or constitutes both Revolving Facility First Lien Collateral and Term Facility First Lien Collateral, then the Revolving Facility Agent and the Term Facility Agent will work jointly and in good faith to collect, adjust or settle (subject to the rights of the Grantors under the Revolving Facility Debt Documents and the Term Facility Debt Documents) under the relevant insurance policy.

SECTION 2.10. Refinancings and Additional Secured Debt. The Revolving Facility Obligations and the Term Facility Obligations may be Replaced, by any Revolving Substitute Facility or Term Substitute Facility, as the case may be, in each case, without notice to, or the consent of any Secured Party, all without affecting the Lien priorities provided for herein or the other provisions hereof; provided, however, that the Term Facility Agent and the Revolving Facility Agent shall receive on or prior to incurrence of the Replacement of a Revolving Substitute Facility or Term Substitute Facility (i) an Officers’ Certificate from Holdings stating that (A) the Replacement is permitted by each other applicable Secured Document to be incurred or to the extent a consent is otherwise required to permit the Replacement under any other Secured Document, Holdings and each other Grantor have obtained the requisite consent and (B) the requirements of Section 2.12 have been satisfied, and (ii) a Lien Sharing and Priority Confirmation Joinder from the holders or lenders of any indebtedness that Replaces the Revolving Facility Obligations or the Term Facility Obligations (or an authorized agent, trustee or other representative on their behalf).

Each of the then-exiting Revolving Facility Agent and the Term Facility Agent, as applicable, shall be authorized to execute and deliver such documents and agreements (including amendments or supplements to this Agreement) as such holders, lenders, agent, trustee or other representative may reasonably request to give effect to such Replacement, it being understood that the Revolving Facility Agent and the Term Facility Agent, without the consent of any other Secured Party, may amend, supplement, modify or restate this Agreement to the extent necessary or appropriate to facilitate such amendments or supplements to effect such Replacement all at the expense of Holdings; provided that in the event that such amendments, supplements, modifications or restatements materially adversely affect the rights of the Grantors under the Secured Documents or imposes material additional obligations or liability on any Grantor or any Subsidiary of Holdings, then the written consent of Holdings will be required prior thereto. Upon the consummation of such Replacement and the execution and delivery of the documents and agreements contemplated in the preceding sentence, the holders or lenders of such indebtedness and any authorized agent, trustee or other representative thereof shall be entitled to the benefits of this Agreement.

Notwithstanding the foregoing, nothing in this Agreement will be construed to allow any Loan Party to incur additional indebtedness unless otherwise permitted by the terms of each applicable Secured Document.

SECTION 2.11. Amendments to Security Documents. (a) Without the prior written consent of the Senior Representative, no Junior Secured Obligations Security Document may be amended, supplemented or otherwise modified or entered into to the extent such amendment, supplement or modification, or the terms of any new Junior Secured Obligations Security Document, would be prohibited by, or would require any Grantor to act or refrain from acting in a manner that would violate, any of the terms of this Agreement.

(b) In the event that the Senior Secured Obligations Secured Parties or the Senior Representative and Holdings or any other Grantors thereunder enters into any amendment, waiver or consent in respect of any of the Senior Secured Obligations Security Documents for the purpose of adding to, or deleting from, or waiving or consenting to any departures from any provisions of, any Senior Secured Obligations Security Document or changing in any manner the rights of the Senior Representative, the Senior Secured Obligations Secured Parties, Holdings or any other Grantor thereunder (including the release of any Liens in Senior Secured Obligations Collateral to the extent permitted by Section 2.05), then such amendment, waiver or consent shall apply automatically to any comparable provision of the comparable Junior Secured Obligations Security Document without the consent of the Junior Representative or any Junior Secured Obligations Secured Party and without any action by the Junior Representative; provided, however, that reasonable prior written notice of such amendment, waiver or consent shall have been given to the Junior Representative. The Junior Representative and each Junior Secured Obligations Secured Party agree to take such action and execute such documents as reasonably requested by the Senior Representative or Holdings to carry out the purpose and intent of this Section 2.11(b).

SECTION 2.12. Legends. The Revolving Facility Agent acknowledges with respect to the Revolving Facility Credit Agreement and the Revolving Facility Security Documents, on the one hand, and the Term Facility Agent acknowledges with respect to the Term Facility Credit Agreement and the Term Facility Security Documents, on the other hand, that the Revolving Facility Credit Agreement and the Term Facility Credit Agreement and each associated Security Document granting any security interest in the Collateral will contain the appropriate legend set forth on Annex I.

SECTION 2.13. Junior Secured Obligations Secured Parties Rights as Unsecured Creditors. Notwithstanding the provisions of Sections 2.02, 2.04(a) and 2.06(b), (c) and (d) or otherwise, both before and during an Insolvency or Liquidation Proceeding, any of the Junior Secured Obligations Secured Parties may take any actions and exercise any and all rights that would be available to a holder of unsecured claims, including, without limitation, the commencement of an Insolvency or Liquidation Proceeding against Holdings or any other Grantor in accordance with applicable law; provided, that the Junior Secured Obligations Secured Parties may not take any of the

actions prohibited by Section 2.02, clauses (i) through (vii) of Section 2.04(a) or Section 2.06(b), (c) and (d); provided, further, that in the event that any of the Junior Secured Obligations Secured Parties becomes a judgment lien creditor in respect of any Collateral as a result of its enforcement of its rights as an unsecured creditor with respect to the Junior Secured Obligations, such judgment lien shall be subject to the terms of this Agreement for all purposes (including in relation to the Senior Secured Obligations) as the other Liens securing the Junior Secured Obligations are subject to this Agreement.

Gratuitous Bailment for Perfection of Certain Security Interests; Rights Under Permits and Licenses

SECTION 3.01. General. The Senior Representative agrees that if it shall at any time hold a Senior Lien on any Junior Secured Obligations Collateral that can be perfected by the possession or control of such Collateral or of any account in which such Collateral is held, and if such Collateral or any such account is in fact in the possession or under the control of the Senior Representative, the Senior Representative will serve as gratuitous bailee for the Junior Representative for the sole purpose of perfecting the Junior Lien of the Junior Representative on such Collateral. It is agreed that the obligations of the Senior Representative and the rights of the Junior Representative and the other Junior Secured Obligations Secured Parties in connection with any such bailment arrangement will be in all respects subject to the provisions of Article II. Notwithstanding anything to the contrary herein, the Senior Representative will be deemed to make no representation as to the adequacy of the steps taken by it to perfect the Junior Lien on any such Collateral and shall have no responsibility, duty, obligation or liability to the Junior Representative or other Junior Secured Obligations Secured Party or any other person for such perfection or failure to perfect, it being understood that the sole purpose of this Article is to enable the Junior Secured Obligations Secured Parties to obtain a perfected Junior Lien in such Collateral to the extent, if any, that such perfection results from the possession or control of such Collateral or any such account by the Senior Representative. Subject to Section 2.07, from and after the associated Discharge of Senior Secured Debt Obligations, the Senior Representative shall take all such actions in its power as shall reasonably be requested by the Junior Representative (at the sole cost and expense of the Grantors) to transfer possession or control of such Collateral or any such account (in each case to the extent the Junior Representative has a Lien on such Collateral or account after giving effect to any prior or concurrent releases of Liens) to the Junior Representative (and with respect to any Collateral constituting (i) Revolving Facility First Lien Collateral, to the Term Facility Agent for the benefit of all applicable Junior Secured Obligations Secured Parties and (ii) Term Loan First Lien Collateral, to the Revolving Facility Agent for the benefit of all applicable Junior Secured Obligations Secured Parties).

(a) The Grantors, to the extent required by the Revolving Facility Credit Agreement, may from time to time establish deposit accounts (the “Deposit

Accounts”) with certain depositary banks in which collections from Inventory and Accounts may be deposited. To the extent that any such Deposit Account is under the control of the Revolving Facility Agent at any time, the Revolving Facility Agent will act as gratuitous bailee for the Term Facility Agent for the purpose of perfecting the Liens of the Term Facility Secured Parties in such Deposit Accounts and the cash and other assets therein as provided in Section 3.01 (but will have no duty, responsibility or obligation to the Term Facility Secured Parties (including, without limitation, any duty, responsibility or obligation as to the maintenance of such control, the effect of such arrangement or the establishment of such perfection) except as set forth in the last sentence of this Section 3.02(a)). Unless the Junior Liens on such Revolving Facility First Lien Collateral shall have been or concurrently are released, after the occurrence of Discharge of Senior Secured Debt Obligations, the Revolving Facility Agent shall, at the request of the Term Facility Agent, cooperate with the Grantors and the Term Facility Agent (at the expense of the Grantors) in permitting control of any other Deposit Accounts to be transferred to the Term Facility Agent (or for other arrangements with respect to each such Deposit Accounts reasonably satisfactory to the Term Facility Agent to be made).

(b) To the extent that the Term Facility First Lien Account is under the control of the Term Facility Agent at any time, the Term Facility Agent will act as gratuitous bailee for the Revolving Facility Agent for the purpose of perfecting the Liens of the Revolving Facility Secured Parties in such account and the cash and other assets therein as provided in Section 3.01 (but will have no duty, responsibility or obligation to the Revolving Facility Secured Parties (including, without limitation, any duty, responsibility or obligation as to the maintenance of such control, the effect of such arrangement or the establishment of such perfection) except as set forth in the last sentence of this Section 3.02(b)). Unless the Junior Liens on such Term Facility First Lien Collateral shall have been or concurrently are released, after the occurrence of Discharge of Senior Secured Debt Obligations, the Term Facility Agent shall, at the request of the Revolving Facility Agent, cooperate with the Grantors and the Revolving Facility Agent (at the expense of the Grantors) in permitting control of such account to be transferred to the Revolving Facility Agent (or for other arrangements with respect to each such account reasonably satisfactory to the Revolving Facility Agent to be made).

SECTION 3.03. Rights under Permits and Licenses. The Term Facility Agent agrees that if the Revolving Facility Agent shall require rights available under any permit or license controlled by the Term Facility Agent (as certified to the Term Facility Agent by the Revolving Facility Agent, upon which the Term Facility Agent may rely) in order to realize on any Revolving Facility First Lien Collateral, the Term Facility Agent shall (subject to the terms of the Term Facility Credit Agreement, including the Term Facility Agent’s rights to indemnification thereunder) take all such actions as shall be available to it (at the sole expense of the Grantors), consistent with applicable law and reasonably requested by the Revolving Facility Agent in writing, to make such rights available to the Revolving Facility Agent, subject to the Term Facility Liens. The Revolving Facility Agent agrees that if the Term Facility Agent shall require rights available under any permit or license controlled by the Revolving Facility Agent (as

certified to the Revolving Facility Agent by the Term Facility Agent, upon which the Revolving Facility Agent may rely) in order to realize on any Term Facility First Lien Collateral, the Revolving Facility Agent shall take all such actions as shall be available to it (at the sole expense of the Grantors), consistent with applicable law and reasonably requested by the Term Facility Agent in writing, to make such rights available to the Term Facility Agent, subject to the Revolving Facility Liens.

SECTION 3.04. Grantors’ Actions Regarding Collateral. To the extent any Secured Document requires any Grantor to deliver any certificate, instrument, promissory note, chattel paper, control agreement or proceeds or to take any other action with respect to the perfection of (or the realization of benefits on) the Revolving Facility Liens or the Term Facility Liens on any item of Collateral, and to the extent such delivery or other action is of such nature that it may not be made or taken with respect to both the Senior Liens and the Junior Liens concurrently (for example, the granting of exclusive control (as defined in the New York UCC) to one but not both Representatives with respect to bank accounts), such Grantor shall make such delivery or take such other action so required under the applicable Senior Document with respect to such item of Collateral and the Senior Representative shall comply with this Article III and other applicable provisions of this Agreement with respect to such item of Collateral (which delivery or other action by such Grantor will be deemed to satisfy any such requirement under the applicable Junior Documents).

Whenever a 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 Senior Secured Obligations (or the existence of any commitment to extend credit that would constitute Senior Secured Obligations) or Junior Secured Obligations, or the existence of any Lien securing any such obligations, or the Collateral subject to any such Lien, it may request that such information be furnished to it in writing by the other Representative and shall be entitled to make such determination on the basis of the information so furnished; provided, however, that if a Representative shall fail or refuse reasonably promptly to provide the requested information, the requesting Representative shall be entitled to make any such determination by such customary method as it may, in the exercise of its good faith judgment, determine, including by reliance upon a certificate of Holdings. Each Representative may, absent manifest error, 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 Holdings or any of their Subsidiaries, any Secured Party or any other person as a result of such determination.

Each Grantor hereby consents to the provisions of this Agreement and the intercreditor arrangements provided for herein and agrees that the obligations of the Grantors under the Security Documents will in no way be diminished or otherwise affected by such provisions or arrangements (except as expressly provided herein).

SECTION 7.02. 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. The rights and remedies of the parties hereto are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or consent to any departure by any party therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice or demand on any party hereto in any case shall entitle such party to any other or further notice or demand in similar or other circumstances.

(b) Neither this Agreement nor any provision hereof may be terminated, waived, amended or modified except pursuant to an agreement or agreements in writing entered into by each Representative and, if such termination,

waiver, amendment or modification materially adversely affects the rights of the Grantors under the Secured Documents or imposes material additional obligations or liability on any Grantor or any Subsidiary of Holdings, then the written consent of Holdings will be required prior to such termination, waiver, amendment or modification; provided, however, that this Agreement may be amended from time to time (x) as provided in Section 2.10 and (y) at the sole request and expense of Holdings, and without the consent of either Representative, to add, pursuant to the Intercreditor Agreement Joinder, additional Grantors whereupon such Person will be bound by the terms hereof to the same extent as if it had executed and delivered this Agreement as of the date hereof.

SECTION 7.03. Parties in Interest. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns, as well as the other Secured Parties, all of whom are intended to be bound by, and to be third party beneficiaries of, this Agreement.

SECTION 7.04. Survival of Agreement. This is a continuing agreement of lien subordination and may not be revoked.

SECTION 7.06. Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

SECTION 7.07. Governing Law; Jurisdiction; Consent to Service of Process. (a) This Agreement shall be construed in accordance with and governed by the laws of the State of New York (and to the extent applicable prior to the Exit Facility Conversion Date (as defined in the Revolving Facility Credit Agreement) the Bankruptcy Code).

(b) Each party hereto hereby irrevocably and unconditionally submits, for itself and its property, to the exclusive jurisdiction of the Supreme Court of the State of New York sitting in New York County and of the United States District Court of the Southern District of New York, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent permitted by law, in such federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement shall affect any right that any party hereto may otherwise have to bring any action or proceeding relating to this Agreement in the courts of any jurisdiction.

(c) Each party hereto hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement in any court referred to in paragraph (b) of this Section. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(d) Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 7.01. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

SECTION 7.08. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT. EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

SECTION 7.09. Headings. Article, Section and Annex headings used herein are for convenience of reference only, are not part of this Agreement and are not to affect the construction of, or to be taken into consideration in interpreting, this Agreement.

SECTION 7.10. Conflicts. In the event of any conflict or inconsistency between the provisions of this Agreement and the provisions of any Secured Documents, the Other Secured Agreements, in each case whether as defined in the Term Facility Credit Agreement or the Revolving Facility Credit Agreement, the provisions of this Agreement shall control.

SECTION 7.11. Provisions Solely to Define Relative Rights. Except as otherwise provided, the provisions of this Agreement are and are intended solely for the purpose of defining the relative rights of the Revolving Facility Secured Parties, on the one hand, and the Term Facility Secured Parties, as the case may be, on the other hand. None of Holdings, any other Grantor or any other creditor thereof shall have any rights or obligations hereunder, except as expressly provided in this Agreement (provided that nothing in this Agreement (other than Sections 2.05, 2.06, 2.10, 2.11 or Article VII) is intended to or will amend, waive or otherwise modify the provisions of the Revolving Facility Credit Agreement or the Term Facility Credit Agreement), and neither Holdings nor any other Grantor may rely on the terms hereof (other than Sections 2.05, 2.06, 2.10, 2.11, Article VI and Article VII). Nothing in this Agreement is intended to or shall impair the obligations of Holdings or any other Grantor, which are absolute and unconditional, to pay the Obligations under the Secured Documents as and when the same shall become due and payable in accordance with their terms. Notwithstanding anything to the contrary herein or in any Secured Document, the Grantors shall not be required to act or refrain from acting (a) pursuant to this Agreement or any Term Facility Debt Document, the Other Secured Agreements (as defined under the Term Facility Credit Agreement), in each case as defined in the Term Facility Credit Agreement, with respect to any Revolving Facility First Lien Collateral in any manner that would cause a default under any Revolving Facility Debt Document, or (b) pursuant to this Agreement or any Revolving Facility Debt Document or any Other Secured Agreement (as defined in the Revolving Facility Credit Agreement) with respect to any Term Facility First Lien Collateral in any manner that would cause a default under any Term Facility Debt Document.

SECTION 7.12. Certain Terms Concerning Revolving Facility Agent and Term Facility Agent. Neither the Revolving Facility Agent nor the Term Facility Agent shall have any liability or responsibility for the actions or omissions of any other Secured Party, or for any other Secured Party’s compliance with (or failure to comply with) the terms of this Agreement. Neither the Revolving Facility Agent nor the Term Facility Agent shall have individual liability to any Person if it shall mistakenly pay over or distribute to any Secured Party (or Holdings) any amounts in violation of the terms of this Agreement, so long as the Revolving Facility Agent or the Term Facility Agent, as the case may be, is acting in good faith.

SECTION 7.13. Subrogation. Each Junior Representative, on behalf of itself and the Junior Secured Obligations Secured Parties, hereby waives any rights of subrogation it may acquire as a result of any payment hereunder until the Discharge of Senior Secured Debt Obligations has occurred.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed by their respective authorized officers as of the day and year first above written.
