Each Grantor and the Collateral Agent hereby acknowledge and agree that, with respect to any ITU Application included within the Collateral, to the extent such an ITU Application would, under the Trademark Act, be deemed to be transferred in violation of 15 U.S.C. § 1060(a) as a result of the security interest granted herein, or otherwise invalidated or made unenforceable as a result of the execution or performance of this Agreement, no security interest shall be deemed to have been granted in such ITU Application (notwithstanding the provisions of this Agreement or any other Indenture Document) until such time as the circumstances that would give rise to such violation, invalidation or unenforceability no longer exist.

(ii) If any Pledged Securities are evidenced by certificates, then the Grantor of such Pledged Securities shall concurrently herewith deposit with the Collateral Agent, for the benefit of itself and the other Secured Parties, in accordance with the terms of the Intercreditor Agreement, the Pledged Securities owned by such Grantor on the date hereof and the certificates representing the Pledged Securities endorsed in blank by such Grantor or accompanied by undated stock powers or instruments of transfer, in each case, duly executed in blank by such Grantor.

3.2 Subsequently Acquired Pledged Securities. (i) If at any time or from time to time after the date hereof during the term of this Agreement, any Grantor shall acquire any additional Pledged Securities, including any further stock, or equity in each Issuer (whether by purchase, dividend, merger, consolidation, sale of assets, split, spin-off, or any other dividend or distribution of any kind or otherwise) (collectively, the "Future Rights") (provided, however, that Future Rights under this clause shall exclude any Future Rights to the extent and only to the extent that (x) their inclusion would cause the number of shares or units, as the case may be, of Capital Stock pledged hereunder to exceed the Designated Number or (y) such Future Rights would constitute Excluded Capital Stock, in each case, after giving effect to the issuance of such Future Rights and any related issuances).

(ii) Such Grantor will forthwith pledge and, if applicable, deposit such additional Pledged Securities with the Collateral Agent, for the benefit of itself and, the other Secured Parties and deliver to the Collateral Agent, for the benefit of itself and the other Secured Parties, certificates or instruments therefor, endorsed in blank by such Grantor or accompanied by undated stock powers or instruments of transfer, in each case, duly executed in blank by such Grantor, and will promptly thereafter deliver to the Collateral Agent, for the benefit of itself and the other Secured Parties, a certificate (which shall be deemed to supplement the attached Exhibit E hereto with respect to such Grantor) executed by such Grantor describing such Pledged Securities and the other Pledged Securities pledged to the Collateral Agent, and certifying that the same have been duly pledged with the Collateral Agent hereunder. For the avoidance of doubt, if any certificate or instrument representing any such additional Pledged Securities also represents any Capital Stock that constitutes an Excluded Asset described in clause 6 or clause 8 of the definition thereof, the Lien created hereunder shall only attach to the Capital Stock evidenced thereby to the extent such Capital Stock does not constitute an Excluded Asset described in clause 6 or clause 8 of the definition thereof.

(iii) Whether or not such additional Pledged Securities are evidenced by certificates, such Grantor shall, and hereby authorizes the Collateral Agent to, file a U.C.C. Financing Statement naming such Grantor as debtor and the Collateral Agent as secured party with respect to the additional Collateral in the applicable filing office and in such form and containing such substance as may be necessary to perfect the security interest of the Collateral Agent in the additional Pledged Securities by the filing of a U.C.C. Financing Statement; provided, however, that no such authorization shall obligate the Collateral Agent to make any such filing.

3.3 Uncertificated Pledged Securities. In addition to anything contained in Sections 3.1 and 3.2 hereof, if any Collateral (whether now owned or hereafter acquired) are not certificated or becomes an uncertificated security, the applicable Grantor shall promptly notify the Collateral Agent in writing thereof and shall promptly take all actions required to perfect or improve the perfection of the security interest and pledge in favor of the Collateral Agent under applicable law (including, in any event, any action required or appropriate under this Agreement or the U.C.C.). Such Grantor further agrees to take such actions as may be necessary to permit the Collateral Agent to exercise any of its rights and remedies hereunder.

3.4 Voting, etc. Until the occurrence and continuance of an Event of Default, each Grantor shall be entitled to vote any and all of the Pledged Securities; provided; however, that no vote shall be cast or any action taken by such Grantor with respect to any Pledged Securities which would violate or be materially inconsistent with any of the terms of this Agreement, the Indenture, any other Indenture Document, or which would have the effect of materially impairing the position or interests of the Collateral Agent or which would authorize or effect actions prohibited under the terms of the Indenture or any Indenture Document. All such rights of such Grantor to vote any Pledged Securities shall cease upon the occurrence and during the continuance of an Event of Default, if the Collateral Agent so directs and provides notice to such Grantor to do so; provided, however, that upon the cure or waiver of such Event of Default, all rights of the Collateral Agent to vote any and all of the Pledged Securities shall cease.

3.5 Payments and Other Distributions. Until the occurrence and continuance of an Event of Default and subject in all cases to the Intercreditor Agreement, all cash, dividends or distributions payable in respect of the Pledged Securities (to the extent such payments shall be permitted pursuant to the terms and provisions of the Indenture) shall be paid to the applicable Grantor; provided, however, upon the occurrence and during the continuance of an Event of Default, all cash dividends or distributions payable in respect of the Pledged Securities shall be paid to the Collateral Agent as security for the Obligations if the Collateral Agent so directs and provides notice to such Grantor to that effect; provided, further that upon the cure or waiver of such Event

of Default, all cash dividends or distributions payable in respect of the Pledged Securities shall be paid to such Grantor. The Collateral Agent shall be entitled to receive directly, and to retain as part of the Pledged Securities:

(a) all other or additional securities or investment property, or rights to subscribe for or purchase any of the foregoing, or property (other than cash) paid or distributed by way of dividend in respect of the Pledged Securities (excluding any of the foregoing items in the preceding clause with respect to an Issuer to the extent and only to the extent that their inclusion would cause (i) the number of shares or units, as the case may be, of such other or additional securities or Investment Property pledged hereunder to exceed the Designated Number or (ii) such Pledged Securities to constitute Excluded Capital Stock, in each case, after giving effect to such issuances); and

(b) all other or additional securities, investment property or property (including cash) paid or distributed in respect of the Pledged Securities by way of split, spin-off, split-up, reclassification, combination of shares or similar rearrangement (excluding any of the foregoing items in the preceding clause with respect to an Issuer to the extent and only to the extent that their inclusion would cause (i) the number of shares or units, as the case may be, of Capital Stock pledged hereunder to exceed the Designated Number or (ii) such other or additional securities or investment property to constitute Excluded Capital Stock, in each case, after giving effect to such issuances).

Subject to the Intercreditor Agreement, if at any time any Grantor shall obtain or possess any of the foregoing Pledged Securities described in this Section, such Grantor shall be deemed to hold such Pledged Securities in trust for the Collateral Agent for the benefit of the Collateral Agent and the other Secured Parties, and such Grantor shall promptly surrender and deliver such Pledged Securities to the Collateral Agent.

Excluding intercompany liabilities, no Grantor is insolvent, as defined in any applicable state or federal statute, nor will any Grantor be rendered insolvent by the execution and delivery of this Agreement to the Collateral Agent or any other documents executed and delivered to the Collateral Agent or the Secured Parties in connection herewith. No Grantor has engaged, nor is any Grantor about to engage, in any business or transaction for which the assets retained by it are or will be an unreasonably small amount of capital, taking into consideration the obligations to the Secured Parties incurred hereunder. No Grantor intends to, nor does any Grantor believe that it will, incur debts beyond its ability to pay such debts as they mature.

5. Covenants

5.1 Filing of Financing Statements; Delivery of Additional Documentation Required. (a) Each Grantor hereby authorizes the Collateral Agent to file U.C.C. Financing Statements necessary or desirable to effectuate the transactions contemplated by the Indenture Documents, and any continuation statement or amendment with respect thereto, including an "all assets" financing statement, in any appropriate filing office; provided, however, that no such authorization shall obligate the Collateral Agent to make any such filing.

(b) Each Grantor shall prepare, execute and deliver to, and if applicable, file, any and all financing statements, original financing statements in lieu of continuation statements, amendments to financing statements, fixture filings, security agreements, pledges, assignments, Commercial Tort Claim Assignments, endorsements of certificates of title, and all other documents (collectively, the "Additional Documents") as may be necessary (and to the extent the Collateral Agent is a party thereto, in form and substance reasonably satisfactory to the Collateral Agent) to create, perfect, and continue the perfection of or to improve the priority the Collateral Agent's Liens in the Collateral of such Grantor (whether now owned or hereafter arising or acquired or tangible or intangible), or to fully consummate all of the transactions contemplated hereby and under the other Indenture Documents. Not in limitation but in furtherance of the foregoing, the Company shall comply with its obligations in the immediately preceding sentence as such obligations relate

to the preparation and filing by it of a U.C.C. Financing Statement, together with any applicable filing fees, within 10 days of the date hereof in the applicable filing office, and following the filing thereof shall provide the Collateral Agent with evidence of the same. To the maximum extent permitted by applicable law, such Grantor authorizes the Collateral Agent to execute any such Additional Documents in such Grantor's name and authorizes the Collateral Agent to file such executed Additional Documents in any appropriate filing office; provided, however, that no such authorization shall obligate the Collateral Agent to take any such action. In addition, no less frequently than annually, each Grantor shall (i) provide the Collateral Agent with a report of all new material patents, patent applications, trademarks, trademark applications, copyrights or copyright applications acquired or generated by such Grantor during the prior period and (ii) cause to be prepared, executed, and delivered to the Collateral Agent supplemental schedules to the applicable Collateral Agreements to identify such patents, copyrights, and trademarks as being subject to the security interests created thereunder; provided, however, that no Grantor shall register or apply to register with (A) the United States Copyright Office any unregistered copyrights (whether in existence on the Issue Date or thereafter acquired, arising, or developed) unless within 30 days of any such registration or application for registration, such Grantor executes and delivers to the Collateral Agent and files with the United States Copyright Office an Intellectual Property Security Agreement, supplemental schedules to any existing Intellectual Property Security Agreement, or such other documentation as may be necessary in order to perfect and continue the perfection of or protect the Collateral Agent's Liens on such copyrights following such registration or (B) the United States Patent and Trademark Office any unregistered patents or trademarks (whether in existence on the Issue Date or thereafter acquired, arising, or developed) unless within 30 days of any such registration or application for registration, the applicable Person executes and delivers to the Collateral Agent and files with the United States Patent and Trademark Office an Intellectual Property Security Agreement, supplemental schedules to any existing Intellectual Property Security Agreement, or such other documentation as may be necessary in order to perfect and continue the perfection of or protect the Collateral Agent's Liens on such patents or trademarks following such registration. If the Collateral Agent does not receive an updated report from the Grantors, the Collateral Agent may assume that no further intellectual property was created or is in the need of updating and the Collateral agent need not undertake an investigation into any such issues. The Company shall submit the Intellectual Property Security Agreement executed by it as of the date hereof for filing with the United States Copyright Office and the United States Patent and Trademark Office, as applicable, together with all necessary filing, registration or similar fees, within 30 days of the date hereof, and following such submission thereof shall provide the Collateral Agent with evidence of the same.

5.2 Insurance. Each Grantor covenants and agrees that such Grantor shall, at such Grantor's expense, maintain insurance respecting its assets wherever located, covering loss or damage by fire, theft, explosion, and all other hazards and risks and in such amounts as ordinarily are insured against by other Persons engaged in the same or similar businesses. Such Grantor also shall maintain business interruption, public liability, and product liability insurance, as well as insurance against larceny, embezzlement, and criminal misappropriation. Such Grantor shall deliver copies of all such policies or certificates of insurance evidencing the same to the Collateral Agent with an endorsement naming the Collateral Agent as loss payee (under a satisfactory lender's loss payable endorsement) or additional insured, as appropriate. Each policy of insurance or endorsement shall contain a clause requiring the insurer to give not less than 30 days prior written notice to the Collateral Agent in the event of cancellation of any such policy for any reason whatsoever;

5.3 Location of Inventory and Equipment. Each Grantor covenants and agrees that such Grantor shall keep such Grantor's Inventory and Equipment only at the locations identified on Schedule 4.4 and its chief executive offices only at the locations identified on Schedule 4.4;

provided, however, that such Grantor may amend Schedule 4.4 so long as such amendment occurs by prompt written notice to the Collateral Agent, and so long as such new location is within the continental United States or Canada.

5.4 Property Acquired Subsequent to the Closing Date and Right to Take Additional Collateral. Each Grantor shall provide the Collateral Agent with prompt written notice with respect to any real or personal property (other than in the ordinary course of business and excluding Accounts, Inventory, Equipment and General Intangibles and other property acquired in the ordinary course of business or any Investment Property that constitutes securities of a Foreign Subsidiary not required to be pledged pursuant to this Agreement) acquired by any Grantor subsequent to the date hereof. In addition to any other right that the Collateral Agent and the Secured Parties may have pursuant to this Agreement or otherwise, the Company shall, and shall cause each Guarantor to, grant to the Collateral Agent, for the benefit of the Secured Parties, as additional security for the Obligations, a first (or, in the case of the Indenture Priority Collateral (as such defined in the Intercreditor Agreement), so long as the Intercreditor Agreement is in effect, a second) Lien on any real or personal property of the Company and each Guarantor (other than Excluded Assets). Each Grantor agrees to secure, within twenty (20) days after the date of such acquisition, all of the Obligations by delivering to the Collateral Agent, as applicable, security agreements, intellectual property security agreements, pledge agreements, mortgages (or deeds of trust, if applicable) or other documents, instruments or agreements with respect to any of the Grantors. The Company shall perform and pay all recordation, legal and other expenses in connection therewith.

5.5 Deposit Accounts and Securities Accounts. (a) No later than sixty (60) days after the Issue Date (unless a longer period has been agreed to by the Administrative Agent), the Company shall have delivered to the Administrative Agent an executed Control Agreement, for each Deposit Account maintained by a Grantor; provided that the Company shall not be required to deliver a Control Agreement with respect to any of the Deposit Accounts referenced in the next sentence, so long as the Company is in compliance with this sentence. No later than one hundred (100) days after the Issue Date (unless a longer period has been agreed to by the Administrative Agent), the Company shall have closed the Deposit Accounts designated as Deposit Accounts to be closed in Schedule 5.5 hereto.

(b) Subject to Section 5.5(a), each Grantor covenants and agrees that such Grantor will not maintain, on or after the date that is 60 days following the Issue Date, any Deposit Account or Securities Account having an average closing balance in excess of (i) $100,000, individually, or (ii) $500,000, in the aggregate, in each case, for any five consecutive Business Day period unless such Grantor and the applicable securities intermediary or bank shall have entered into a Control Agreement governing such Deposit Account or Securities Account, as the case may be, in order to perfect or improve the priority of the Collateral Agent's Liens therein. Each Grantor agrees that it will take all commercially reasonable steps in order for the Collateral Agent or the Administrative Agent as contemplated by the Intercreditor Agreement to obtain control in accordance with Sections 8-106, 9-104, 9-105, 9-106, and 9-107 of the U.C.C. with respect to all of its Securities Accounts, Deposit Accounts, electronic chattel paper, Investment Property, and letter-of-credit rights (other than Deposit Accounts and Securities Accounts having an average closing balance in excess of (i) $100,000, individually, or (ii) $500,000, in the aggregate, in each case, for any five consecutive Business Day period). Subject to the Intercreditor Agreement, upon the occurrence and during the continuance of an Event of Default, the Collateral Agent may notify any bank or securities intermediary subject to a Control Agreement to liquidate the applicable Deposit Account or Securities Account or any related Investment Property maintained or held thereby and remit the proceeds thereof to the Collateral Agent.

5.6 Right to Inspect. The Collateral Agent (through any of its officers, employees, or agents) shall have the right (but not the obligation) no more frequently than annually (unless an Event of

Default is outstanding) to inspect the Books of any Grantor and make copies or abstracts thereof and to check, test, and appraise the Collateral, or any portion thereof, in order to verify each Grantor's financial condition or the amount, quality, value, condition of, or any other matter relating to, the Collateral at such reasonable times as the Collateral Agent may designate, and so long as no Default or Event of Default has occurred and is continuing, with reasonable prior notice.

6. Corporate Names and Location of Collateral. No Grantor shall (a) change its name, or (b) change its jurisdiction or form of organization or extend or continue its existence in or to any other jurisdiction (other than its jurisdiction of organization at the date of this Agreement) unless such Grantor shall have provided the Collateral Agent with any and all Additional Documents necessary to maintain the perfection of the Collateral Agent's Liens on the Collateral. Each Grantor shall also provide the Collateral Agent with prior written notification of (i) any new locations where any of the Inventory or Equipment of such Grantor is to be maintained; (ii) the location of any new places of business or the changing or closing of any of its existing places of business; and (iii) any change in such Grantor's chief executive office. In the event of any of the foregoing the Grantor shall, and the Collateral Agent is hereby authorized to file new U.C.C. Financing Statements describing the Collateral and otherwise in form and substance sufficient for recordation wherever necessary, to perfect or continue perfected the security interest of the Collateral Agent, for the benefit of the Secured Parties, in the Collateral, provided, however, that no such authorization shall obligate the Collateral Agent to make any such filing. Grantors shall pay all filing and recording fees and taxes in connection with the filing or recordation of such U.C.C. Financing Statements and shall immediately reimburse the Collateral Agent therefor if the Collateral Agent pays the same. Such amounts not so paid or reimbursed shall be expenses secured by the Lien of this Agreement on the Collateral.

7. Notice. Grantors shall give the Collateral Agent prompt written notice if any Event of Default shall occur hereunder or if the Internal Revenue Service shall allege the nonpayment or underpayment of any tax by any Grantor or threaten to make any assessment in respect thereof.

9. Transfers, Liens and Modifications Regarding Collateral. No Grantor shall, except to the extent not prohibited under the Indenture, sell, assign, transfer or otherwise dispose of, or grant any option with respect to, or create, incur, or permit to exist any pledge, lien, mortgage, hypothecation, security interest, charge, option or any other encumbrance with respect to any of such Grantor's Collateral, or any interest therein, or Proceeds, except for the lien and security interest provided for by this Agreement, any security agreement securing only the Collateral Agent, for the benefit of the Secured Parties and Permitted Liens.

11. Grantors' Obligations with Respect to Intellectual Property.

(a) Subject to the provisions of the Intercreditor Agreement, no Grantor shall sell or assign its interest in, or, except as permitted in the Indenture, grant any license or sublicense with respect to, any Intellectual Property of such Grantor. Any attempted sale or license is null and void. No Grantor shall use the Intellectual Property of such Grantor in any manner that would jeopardize the validity or legal status thereof.

With respect to any Government Contract that is not already subject to an Instrument of Assignment and a Notice of Assignment of Claim, upon the occurrence of an Event of Default, each Grantor shall promptly execute and deliver to the Collateral Agent (i) an Instrument of Assignment, and (ii) a Notice of Assignment of Claim. The Collateral Agent is hereby authorized to file, with the appropriate Governmental Authority, all Instruments of Assignment and Notices of Assignment of Claim required to be delivered to the Collateral Agent under the terms of this Agreement.

Each Grantor agrees to reimburse the Collateral Agent and the Secured Parties in full for all court costs and attorneys' fees and every other cost, expense or liability, if any, incurred or paid by the Collateral Agent or the Secured Parties in connection with the foregoing, which obligation of such Grantor shall constitute Obligations, shall be secured by the Collateral and shall bear interest, until paid, at the Default Rate; and

(g) to accept all collections in any form relating to the Collateral, including remittances that may reflect deductions, and to deposit the same, into a Cash Collateral Account or, at the option of the Collateral Agent (at its election (or at the direction of the Required Holders), to apply them as a payment on the Obligations.

For the better protection of the Collateral Agent and the Secured Parties hereunder, but subject to the Intercreditor Agreement, each Grantor has executed (or will execute, with respect to future Pledged Notes) an appropriate endorsement on (or separate from) each Pledged Note of such Grantor and has deposited (or will deposit, with respect to future Pledged Notes) such Pledged Note with the Collateral Agent, for the benefit of the Secured Parties. Subject to the provisions of the Intercreditor Agreement, each Grantor irrevocably authorizes

16. Commercial Tort Claims.

18. Authorization and Appointments.

(a) Each Grantor hereby irrevocably authorizes and appoints the Company to take all such actions, and exercise all such powers, as are granted to, or contemplated to be taken by, the Company pursuant to the Indenture.

(b) Each Grantor hereby agrees to, and hereby ratifies, all authorizations and appointments granted by such Grantor to the Collateral Agent, or contemplated to be given to the Collateral Agent by such Grantor, under the terms of the Indenture.

19. Default and Remedies.

19.1. The occurrence of an Event of Default, as defined in the Indenture, shall constitute an Event of Default.

19.2. The Collateral Agent and the Secured Parties shall at all times have the rights and remedies of a secured party under the U.C.C. as in effect from time to time, in addition to the

rights and remedies of a secured party provided elsewhere within this Agreement, in any other related document executed by any Grantor or otherwise provided in law or equity. Subject to the provisions of the Intercreditor Agreement, upon the occurrence of an Event of Default and at all times thereafter, the Collateral Agent (at its election (or at the direction of the Required Holders)) may require each Grantor to assemble such Grantor's Collateral, which each Grantor agrees to do, and make it available to the Collateral Agent at a reasonably convenient place to be designated by the Collateral Agent. The Collateral Agent (at its election (or at the direction of the Required Holders)) may, with or without notice to or demand upon any Grantor and with or without the aid of legal process, make use of such force as may be necessary to enter any premises where the Collateral, or any part thereof, may be found and to take possession thereof (including anything found in or on the Collateral that is not specifically described in this Agreement, each of which findings shall be considered to be an accession to and a part of the Collateral) and for that purpose (at its election (or at the direction of the Required Holders)) may pursue the Collateral wherever the same may be found, without liability for trespass or damage caused thereby to a Grantor. After any delivery or taking of possession of the Collateral, or any thereof, pursuant to this Agreement, then, with or without resort to any Grantor or any other Person or property, all of which each Grantor hereby waives, and upon such terms and in such manner as the Collateral Agent may deem advisable, the Collateral Agent (at its election (or at the direction of the Required Holders)) may sell, assign, transfer and deliver any of the Collateral at any time, or from time to time. No prior notice need be given to any Grantor or to any other Person in the case of any sale of Collateral that the Collateral Agent determines to be perishable or to be declining speedily in value or that is customarily sold in any recognized market, but in any other case the Collateral Agent shall give Grantors no fewer than ten days prior notice of either the time and place of any public sale of the Collateral or of the time after which any private sale or other intended disposition thereof is to be made. Each Grantor waives advertisement of any such sale and (except to the extent specifically required by the preceding sentence) waives notice of any kind in respect of any such sale. At any such public sale, the Collateral Agent or any Secured Party may purchase the Collateral, or any part thereof, free from any right of redemption, all of which rights each Grantor hereby waives and releases. After deducting all related expenses, and after paying all claims, if any, secured by liens having precedence over this Agreement, the Collateral Agent may apply the net proceeds of each such sale to or toward the payment of the Obligations, whether or not then due, in such order and by such division as the Collateral Agent (at its election (or at the direction of the Required Holders)) may deem advisable. Any excess, to the extent permitted by law, shall be paid to such Grantor, and the obligors on the Obligations shall remain liable for any deficiency. In addition, during the continuance of an Event of Default, the Collateral Agent shall at all times have the right to obtain new appraisals of each Grantor or the Collateral, the cost of which shall be paid by such Grantor.

20. Maximum Liability of Each Grantor and Rights of Contribution. Anything in this Agreement or any other Loan Document to the contrary notwithstanding, in no event shall the amount of the Obligations secured by this Agreement by any Grantor exceed the maximum amount that (after giving effect to the incurring of the obligations hereunder and to any rights to contribution of such Grantor from other affiliates of the Company) would not render the rights to payment of the Collateral Agent and the Secured Parties hereunder void, voidable or avoidable under any applicable fraudulent transfer law. Grantors hereby agree as among themselves that, in connection with the payments made hereunder, each Grantor shall have a right of contribution from each other Grantor in accordance with applicable law. Such contribution rights shall be waived until such time as the Obligations have been irrevocably paid in full, and no Grantor shall exercise any such contribution rights until the Obligations have been irrevocably paid in full.

21. Reasonable Care by Collateral Agent. The Collateral Agent shall be deemed by each Grantor to have exercised reasonable care in the custody and preservation of the Collateral in its possession if

the Collateral is accorded treatment substantially equal to that which the Collateral Agent accords its own similar property.

22. Indemnity. Without duplication of any amounts payable under any other similar indemnity provision set forth in the Indenture or any other Indenture Documents, each Grantor shall, jointly and severally: (i) pay all out-of-pocket costs and expenses of the Collateral Agent incurred in connection with the administration of and in connection with the preservation of rights under, and enforcement of, and any renegotiating or restructuring of this Agreement and any amendment, waiver or consent relating thereto (including, without limitation, the reasonable fees and disbursements of counsel for the Collateral Agent); (ii) pay and hold the Collateral Agent and the other Secured Parties harmless from and against any and all present and future stamp or documentary taxes or any other excise or property taxes, charges or similar levies which arise from any payment made hereunder or from the execution, delivery or registration of, or otherwise with respect to this Agreement and save the Collateral Agent and the other Secured Parties harmless from and against any and all liabilities with respect to or resulting from any delay or omission to pay any such taxes, charges or levies; and (iii) indemnify the Collateral Agent and each of the other Secured Parties, and each of their respective officers, directors, shareholders, employees, representatives and agents from and hold each of them harmless against any and all costs, losses, liabilities, claims, obligations, suits, penalties, judgments, damages or expenses incurred by or asserted against any of them (whether or not any of them is designated a party thereto) arising out of or by reason of this Agreement or any transaction contemplated hereby (including, without limitation, any investigation, litigation or other proceeding related to this Agreement), including, without limitation, the reasonable fees and disbursements of counsel incurred in connection with any such investigation, litigation or other proceeding. Notwithstanding anything in this Agreement to the contrary, such Grantor shall not be responsible to the Collateral Agent or any other Secured Party for any costs, losses, damages, liabilities or expenses which result from the gross negligence or willful misconduct on the part of such Collateral Agent or any other Secured Party. Each Grantor's obligations under this Section shall survive any termination of this Agreement.

23. Waiver of Claims. Except as otherwise provided in this Agreement or prohibited by law, EACH GRANTOR HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, NOTICE AND JUDICIAL HEARING IN CONNECTION WITH THE COLLATERAL AGENT'S TAKING POSSESSION OR SALE OR THE COLLATERAL AGENT'S DISPOSITION OF ANY OF THE COLLATERAL, INCLUDING, WITHOUT LIMITATION, ANY AND ALL PRIOR NOTICE AND HEARING FOR ANY PREJUDGMENT REMEDY OR REMEDIES AND ANY SUCH RIGHT WHICH SUCH GRANTOR WOULD OTHERWISE HAVE UNDER THE CONSTITUTION OR ANY STATUTE OF THE UNITED STATES OR OF ANY STATE, and each Grantor hereby further waives (and releases any cause of action and claim against the Collateral Agent as a result of), to the fullest extent permitted by law: (a) all damages occasioned by such taking of possession, collection or sale except any damages which are the direct result of the Collateral Agent's gross negligence or willful misconduct; (b) all other requirements as to the time, place and terms of sale or other requirements with respect to the enforcement of the Collateral Agent's rights hereunder; (c) demand of performance or other demand, notice of intent to demand or accelerate, notice of acceleration, presentment, protest, advertisement or notice of any kind to or upon such Grantor or any other person or entity; and (d) all rights of redemption, appraisement, valuation, diligence, stay, extension or moratorium now or hereafter in force under any applicable law in order to delay the enforcement of this Agreement.

24. Interpretation.

No course of dealing by the Collateral Agent in respect of, nor any omission or delay by the Collateral Agent in the exercise of, any right, power or privilege shall operate as a waiver thereof, nor shall any

single or partial exercise of any such right, power or privilege preclude any other or further exercise thereof or of any other right, power or privilege, as the Collateral Agent may exercise each such right, power or privilege either independently or concurrently with others and as often and in such order as the Collateral Agent may deem expedient. No waiver, consent or other agreement shall be deemed to have been made by the Collateral Agent be binding upon the Collateral Agent in any case unless specifically granted by the Collateral Agent in writing, and each such writing shall be strictly construed.

28. Termination. At such time as the Obligations are paid and performed in full (other than contingent indemnification obligations) or the Defeasance thereof shall have been consummated, the Grantors shall have the right to terminate this Agreement. Upon written request of Grantors, the Collateral Agent shall authorize the filing by the Grantors of appropriate termination statements, cancel all control agreements and return all physically pledged Collateral, and Grantors will indemnify the Collateral Agent in all respects for all costs incurred by the Collateral Agent in connection with such termination.

29. Entire Agreement. This Agreement integrates all of the terms and conditions with respect to the Collateral and supersedes all oral representations and negotiations and prior writings, if any, with respect to the subject matter hereof.

(b) Notwithstanding anything to the contrary herein, any provision hereof that requires any Grantor to (i) deliver any Credit Facility Priority Collateral to the Collateral Agent or (ii) provide that the Collateral Agent have control over such Collateral may be satisfied by (A) the delivery of such Collateral by such Grantor to the Administrative Agent for the benefit of the Lenders and the Collateral Agent for the benefit of the Secured Parties pursuant to the Intercreditor Agreement and (B) providing that the Administrative Agent be provided with control with respect to such Collateral of such Grantor for the benefit of the Lenders and the Collateral Agent for the benefit of the Secured Parties pursuant to the Intercreditor Agreement.

30. Governing Law; Submission to Jurisdiction. The provisions of this Agreement and the respective rights and duties of each Grantor, and the Collateral Agent hereunder shall be governed by and construed in accordance with New York law, without regard to principles of conflicts of laws. Each Grantor hereby irrevocably submits to the non-exclusive jurisdiction of any New York state or federal court sitting in New York county, New York, over any such action or proceeding arising out of or relating to this Agreement, any Indenture Document or any related document, and each Grantor hereby irrevocably agrees that all claims in respect of such action or proceeding may be heard and determined in such New York state or federal court.

WHEREAS, New Grantor, a subsidiary of the Company, deems it to be in the direct pecuniary and business interests of New Grantor that the Company continue to obtain from the Secured Parties the financial accommodations provided for in the Indenture;

WHEREAS, New Grantor understands that the Secured Parties are willing to continue grant such financial accommodations only upon certain terms and conditions, one of which is that New Grantor grant to the Collateral Agent, for the benefit of the Secured Parties, a security interest in and a collateral assignment of New Grantor's Collateral, as hereinafter defined, and this Agreement is being executed and delivered in consideration of each financial accommodation granted to the Company by the Secured Parties, and for other valuable consideration;

WHEREAS, pursuant to Section 5.01 of the Indenture and Section 31 of the Security Agreement, New Grantor has agreed that, effective on [ ], [ ] (the "Joinder Effective Date"), New Grantor shall become a party to the Security Agreement and shall become a "Grantor" thereunder; and

WHEREAS, except as specifically defined herein, capitalized terms used herein that are defined in the Security Agreement shall have their respective meanings ascribed to them in the Security Agreement;

NOW, THEREFORE, in consideration of the benefits accruing to New Grantor, the receipt and sufficiency of which are hereby acknowledged, New Grantor hereby makes the following representations and warranties to the Collateral Agent and the Secured Parties, covenants to the Collateral Agent and the Secured Parties, and agrees with the Collateral Agent as follows:

Section 1. Assumption and Joinder. On and after the Joinder Effective Date:

(a) New Grantor hereby irrevocably and unconditionally assumes, agrees to be liable for, and agrees to perform and observe, each and every one of the covenants, rights, promises, agreements, terms, conditions, obligations, appointments, duties and liabilities of a "Grantor" under the Security Agreement and all of the other Indenture Documents (as defined in the Indenture) applicable to it as a Grantor under the Security Agreement;

(b) New Grantor shall become bound by all representations, warranties, covenants, provisions and conditions of the Security Agreement and each other Indenture Document applicable to it as a Grantor

under the Security Agreement, as if New Grantor had been the original party making such representations, warranties and covenants; and

(c) all references to the term "Grantor" in the Security Agreement or in any other Indenture Document, or in any document or instrument executed and delivered or furnished, or to be executed and delivered or furnished, in connection therewith shall be deemed to be a reference to, and shall include, New Grantor.

Section 2. Grant of Security Interests.

(b) Attached hereto as Exhibit A are supplemental schedules to the Indenture, which schedules set forth the information required by the Indenture with respect to New Grantor.

(c) Each of the representations and warranties set forth in the Security Agreement are true and correct in all material respects on as and as of the date hereof as such representations and warranties apply to New Grantor (except to the extent that any such representations and warranties expressly relate to an earlier date) with the same force and effect as if made on the date hereof.
