(a) Secured Guarantees. Each Subsidiary Guarantor unconditionally guarantees to the Collateral Agent for the benefit of the Lenders the full and punctual satisfaction of each Obligation of the Borrower under the Loan Documents when due (whether at stated maturity, upon acceleration or otherwise). If the Borrower fails to satisfy any Obligation punctually when due, each Subsidiary Guarantor jointly and severally agrees that it will forthwith on demand pay the amount not so paid at the place and in the manner specified herein or in any other relevant Loan Document.

(b) Secured Guarantees Unconditional. The obligations of each Subsidiary Guarantor under its Secured Guarantee shall be unconditional and absolute and, without limiting the generality of the foregoing, shall not be released, discharged or otherwise affected by:

(i) any extension, renewal, settlement, compromise, waiver or release in respect of any obligation of the Borrower, any Subsidiary Guarantor or any other Person under any Security Document, by operation of law or otherwise;

(ii) any modification or amendment of or supplement to any Security Document;

(iii) any release, impairment, non-perfection or invalidity of any direct or indirect security for any obligation of the Borrower, any Subsidiary Guarantor or any other Person under any Security Document;

(iv) any change in the corporate existence, structure or ownership of the Borrower, any Subsidiary Guarantor or any other Person or any of their respective subsidiaries, or any insolvency, bankruptcy, reorganization or other similar proceeding affecting the Borrower, any Subsidiary Guarantor or any other Person or any of their assets or any resulting release or discharge of any obligation of the Borrower, any Subsidiary Guarantor or any other Person under any Security Document;

(v) the existence of any claim, set-off or other right that such Subsidiary Guarantor may have at any time against the Borrower, any Subsidiary Guarantor, the Collateral Agent, the Agents, any Lender or any other Person, whether in connection with the Loan Documents or any unrelated transactions, provided that nothing herein shall prevent the assertion of any such claim by separate suit or compulsory counterclaim;

(vi) any invalidity or unenforceability relating to or against the Borrower, any Subsidiary Guarantor or any other Person for any reason of any Security Document, or any provision of applicable law or regulation purporting to prohibit the

payment of any amount in satisfaction of any Obligation by the Borrower, any Subsidiary Guarantor or any other Person; or

(vii) any other act or omission to act or delay of any kind by the Borrower, any Subsidiary Guarantor, any other party to any Security Document, the Collateral Agent, the Agents, any Lender or any other Person, or any other circumstance whatsoever that might, but for the provisions of this Section 2(b)(vii), constitute a legal or equitable discharge of or defense to any obligation of the Borrower or any Subsidiary Guarantor hereunder.

(c) Release of Secured Guarantees. (i) All the Secured Guarantees will be released when all Obligations of the Borrower under the Loan Documents have been satisfied. If at any time any payment in satisfaction of an Obligation is rescinded or must be otherwise restored or returned upon the insolvency or receivership of the Borrower or otherwise, the Secured Guarantees shall be reinstated with respect thereto as though such payment had been due but not made at such time.

(ii) If all the capital stock of a Subsidiary Guarantor or all the assets of a Subsidiary Guarantor are sold to a Person other than a Borrower or a Subsidiary of a Borrower in a transaction not prohibited by the Credit Agreements (any such sale, a “Sale of Subsidiary Guarantor”), the Collateral Agent shall release such Subsidiary Guarantor from its Secured Guarantee. Such release shall not require the consent of the Agents or any Lender, and the Collateral Agent and any third party shall be fully protected in relying on a certificate of the Borrower as to whether any particular sale constitutes a Sale of Subsidiary Guarantor.

(d) Waiver by Subsidiary Guarantors. Each Subsidiary Guarantor irrevocably waives acceptance hereof, presentment, demand, protest and any notice not provided for herein, as well as any requirement that at any time any action be taken by any Person against the Borrower, any Subsidiary Guarantor or any other Person.

(e) Subrogation. Each Subsidiary Guarantor irrevocably waives any and all rights to which it may be entitled, by operation of law or otherwise, upon making any payment hereunder to be subrogated to the rights of the payee with respect to such payment or against any direct or indirect security therefor, or otherwise to be reimbursed, indemnified or exonerated in respect thereof.

(f) Contribution; Subordination. All rights of the Subsidiary Guarantors of contribution and any other rights of indemnity, contribution or subrogation under applicable law or otherwise shall be fully subordinated to the indefeasible payment in full in cash in satisfaction of the Obligations.

(g) Stay of Acceleration. If acceleration of the time for payment of any Obligation by the Borrower is stayed by reason of the insolvency or receivership of the Borrower or otherwise, all Obligations otherwise subject to acceleration under the terms of any Security Document shall nonetheless be payable by the Subsidiary Guarantors hereunder forthwith on demand by the Collateral Agent.

(h) Right of Set-Off. If any Obligation is not paid promptly when due, each of the Lenders and each of their Affiliates which is a Deposit Bank is authorized, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other obligations at any time owing by such Lender or Affiliate to or for the credit or the account of any Subsidiary Guarantor against the obligations of such Subsidiary Guarantor under its Secured Guarantee, irrespective of whether such Lender shall have made any demand thereunder and although such obligations may be unmatured. The rights of each Lender under this subsection are in addition to all other rights and remedies (including other rights of setoff) that such Lender may have and are subject to the provisions of Section 10.7 of the applicable Credit Agreement.

(i) Continuing Guarantee. Each Secured Guarantee is a continuing guarantee, shall be binding on the relevant Subsidiary Guarantor and its successors and assigns, and shall be enforceable by the Collateral Agent. If all or part of any Lender’s interest in any Obligation is assigned or otherwise transferred, the transferor’s rights in respect of each Secured Guarantee, to the extent applicable to the obligation so transferred, shall automatically be transferred with such obligation.

(j) Limitation on Obligations of Subsidiary Guarantors. The obligations of each Subsidiary Guarantor under its Secured Guarantee shall be limited to an aggregate amount equal to the largest amount that would not render such Secured Guarantee subject to avoidance under Section 548 of the United States Bankruptcy Code or any comparable provisions of applicable law.

Section 3. Grant of Liens.

(a) The Borrower, in order to secure its Obligations under the Loan Documents, and each Subsidiary Guarantor listed on the signature pages hereof, in order to secure its Secured Guarantee, grants to the Collateral Agent for the benefit of the Agents and the Lenders a continuing security interest in all the following property of such Borrower or such Subsidiary Guarantor, as the case may be, whether now owned or existing or hereafter acquired or arising and regardless of where located:

(c) The Liens are granted as security only and shall not subject the Collateral Agent or any Lender to, or transfer or in any way affect or modify, any obligation or liability of any Lien Grantor with respect to any of the Collateral or any transaction in connection therewith.

Section 4. General Representations and Warranties. As of the Closing Date and as of the Borrowing Date each Lien Grantor represents and warrants that:

(a) such Lien Grantor is a duly organized, validly existing and in good standing under the laws of the jurisdiction identified as its jurisdiction of organization in its Perfection Certificate;

(b) such Lien Grantor has good and marketable title to all its Collateral (subject to exceptions that are, in the aggregate, not material), free and clear of any Lien other than Permitted Liens;

(c) no financing statement, security agreement, mortgage or similar or equivalent document or instrument covering all or part of the Collateral owned by such Lien Grantor is on file or of record in any jurisdiction in which such filing or recording would be

effective to perfect or record a Lien on such Collateral, except financing statements, mortgages or other similar or equivalent documents with respect to Permitted Liens; and

(d) except for the filing of such UCC financing statements, no other registration, recordation or filing with any governmental body, agency or official is required to establish and perfect the Collateral Agent’s security interest in the General Collateral pursuant to the UCC.

Section 5. Further Assurances, General Covenants.

Each Lien Grantor covenants as follows:

(a) Such Lien Grantor will, from time to time, at the Borrower’s expense, execute, deliver, file and record any statement, assignment, instrument, document, agreement or other paper and take any other action (including any filing of financing or continuation statements under the UCC) that from time to time may be reasonably necessary or desirable, or that the Collateral Agent may reasonably request, in order to:

(i) create, preserve, perfect, confirm or validate the Liens created by the Security Documents on such Lien Grantor’s Collateral;

(ii) enable the Collateral Agent and the Lenders to obtain the full benefits of the Security Documents; or

(iii) enable the Collateral Agent to exercise and enforce any of its rights, powers and remedies with respect to any of such Lien Grantor’s Collateral.

To the extent permitted by applicable law, such Lien Grantor authorizes the Collateral Agent to execute and file such financing statements or continuation statements without such Lien Grantor’s signature appearing thereon. Such Lien Grantor agrees that a copy or reproduction of this Agreement or of a financing statement is sufficient as a financing statement to the extent permitted by law. Each Lien Grantor constitutes the Collateral Agent its attorney-in-fact to execute and file all filings required or so requested for the foregoing purposes, all acts of such attorney being hereby ratified and confirmed; and such power, being coupled with an interest, shall be irrevocable until all the Liens granted by such Lien Grantor terminate pursuant to Section 13. The Borrower will pay the costs of, or incidental to, any recording or filing of any financing or continuation statements or other documents recorded or filed pursuant hereto.

(b) Such Lien Grantor will not (i) change its name or corporate structure, (ii) change its location (determined as provided in UCC Section 9-307) or (iii) except with respect to a Permitted Lien, become bound, as provided in UCC Section 9-203(d) or otherwise, by a security agreement entered into by another Person, unless it shall have given the Collateral Agent prior notice thereof and delivered an Opinion of Counsel with respect thereto in accordance with Section 5(c).

(c) Before it takes any action contemplated by Section 5(b), such Lien Grantor, at the Borrower’s expense, will cause to be delivered to the Collateral Agent an Opinion of Counsel, in form and substance reasonably satisfactory to the Collateral Agent, to the effect

that (i) all financing statements and amendments or supplements thereto, continuation statements and other documents required to be filed or recorded in order to perfect and protect (except with respect to Permitted Liens) the Liens created by the Security Documents against all creditors of and purchasers from such Lien Grantor after it takes such action (except any applicable continuation statements that are to be filed more than six months after the date thereof) have been filed or recorded in each office necessary for such purpose, (ii) all fees and taxes, if any, payable in connection with such filings or recordations have been paid in full, and (iii) such action will not (except with respect to Permitted Liens) adversely affect the perfection or priority of the Lien created by the Security Documents on any Collateral to be owned by such Lien Grantor after it takes such action or the accuracy of such Lien Grantor’s representations and warranties herein relating to the grant and perfection of a security interest in such Collateral.

(d) Except in the ordinary course of business, such Lien Grantor will not sell, lease, exchange, assign or otherwise dispose of, or grant any option with respect to, any of its Collateral; provided that such Lien Grantor may do any of the foregoing unless (i) doing so would violate a covenant in the Credit Agreement, or (ii) the Loans shall have been accelerated pursuant to Section 8 of the Senior Credit Agreement and the Collateral Agent shall have notified such Lien Grantor that its right to do so is terminated, suspended or otherwise limited. Concurrently with any sale or other disposition (except a sale or disposition to another Lien Grantor or a lease) permitted by the foregoing proviso, the Liens created by the Security Documents on the assets sold or disposed of (but not in any Proceeds arising from such sale or disposition) will cease immediately without any action by the Collateral Agent or any Lender. The Collateral Agent will, at the Borrower’s expense, promptly execute and deliver to the relevant Lien Grantor such documents as such Lien Grantor shall reasonably request to evidence the fact that any asset so sold, leased or disposed of is no longer subject to a Lien under any Security Document.

(e) Such Lien Grantor will, promptly upon request, provide to the Collateral Agent all information and evidence concerning such Lien Grantor’s Collateral that the Collateral Agent may reasonably request from time to time to enable it to enforce the provisions of the Security Documents.

Section 6. Accounts.

(a) As of the Closing Date, the Collateral Agent shall have established an account (the “Restricted Account”), in the name and under the exclusive control of the Collateral Agent, the contents of which are to be applied pursuant to this Section 6(a).

(i) the Borrower shall cause (and each other Lien Grantor shall take all actions required on its part to cause) to be deposited in the Restricted Account, promptly upon receipt thereof:

(B) all proceeds collected with respect to the Key Man Insurance and the Key Man Guarantee;

Such cash collateral shall be applied in the same amount and in the same manner as proceeds under the Key Man Guarantee would have been applied and shall be released when and to the extent the Key Man Guarantee would be terminated.

(ii) Unless the maturity of the Loans (or other Obligations) shall have been accelerated pursuant to Section 8 of the Senior Credit Agreement:

(A) The Collateral Agent shall apply the amounts referred to in clauses (A), (B) and (C) of Section 6(a)(i) as specified in the Senior Credit Agreement; and

(B) Amounts specified in clauses (D) and (E) of Section 6(a)(i) shall be paid to or as directed by the Borrower promptly after the submission of the next Borrowing Base Report indicating that such assets are no longer included within the Borrowing Base.

Wachovia Securities shall not be required to be pledged so long as the sole holding in such account is 886 shares (or less) of the common stock of Ace Aviation Holdings, Inc.

(c) Neither the Borrower nor any Lien Grantor shall be required to pledge any Deposit Account established or maintained by it and exclusively used to fund:

(i) current payroll obligations;

(ii) fiduciary obligations (such as pension plans).

(d) The Collateral Agent shall not give the “Notice”, under and as defined in the initial Account Control Agreement (or equivalent notice in any subsequent Account Control Agreement) unless the Loans shall have been accelerated pursuant to Section 8 of the Senior Credit Agreement.

Section 7. Pledged Subsidiary Stock.

(a) Each Lien Grantor shall concurrently with the execution and delivery hereof deliver to the Collateral Agent all certificates representing the Capital Stock of each of its Subsidiaries together with a stock power or powers with respect thereto endorsed in blank and within ten Business Days of forming or acquiring any new Subsidiary will execute and deliver to the Collateral Agent all certificates representing the Capital Stock of such Subsidiary together with a stock power or powers with respect thereto endorsed in blank. The Collateral Agent agrees to hold the same subject to the terms and conditions of this Agreement.

(b) So long as the Loans have not been accelerated pursuant to Section 8 of the Senior Credit Agreement:

(i) Such Lien Grantor shall be entitled to exercise any and all voting and other consensual rights pertaining to the Pledged Subsidiary Stock, or any part thereof, for any purpose not inconsistent with the terms of this Agreement or the other Loan Documents; provided, however, (A) that such Lien Grantor shall not exercise any voting or consensual rights with respect to the commencement of a voluntary case or other proceeding seeking liquidation, reorganization or other relief with respect to such Subsidiary or such Subsidiary’s debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or consent to the entry of an order for relief in an involuntary case under any such law or seeking the appointment of a trustee, receiver, liquidator, sequestrator, assignee, custodian or other similar official of such Subsidiary or any substantial part of such Subsidiary’s property without obtaining the prior written consent of the Collateral Agent; (B) that such Lien Grantor shall not amend or approve any amendment to or modification, alteration or repeal of the Certificate of Incorporation of By-Laws or any other organizational documents, as the case may be, of such Subsidiary without obtaining the prior written consent of the Collateral Agent which consent shall not be unreasonably withheld or delayed; (C) that such Lien Grantor shall not increase the number of directors or modify in any way the composition of the board of directors of the Borrower (other than by replacing any officers or employees of such Lien Grantor or an Affiliate of such Lien Grantor who are directors with other officers or employees of such Lien Grantor or an Affiliate of such Lien Grantor) as same exists as of

the date hereof without obtaining the prior written consent of the Collateral Agent which consent shall not be unreasonably withheld or delayed; and (D) such Lien Grantor shall not approve an increase in the authorized number of shares of stock or stated capital of such Subsidiary or the issuance of any additional shares of stock or the granting of any options or warrants of the without the prior written consent of the Collateral Agent, which consent shall not be unreasonably withheld or delayed provided that the Collateral Agent is granted a first priority security interest in all such shares; and

(C) exercise any or all of the rights and powers and pursue any and all remedies of a secured party under the Uniform Commercial Code of the State of New York.

(ii) Any Lender shall be entitled, at any sale pursuant to this Section 7, to credit against any purchase price bid at such sale by such holder all or any part of the unpaid obligations owing to such Lender and secured by the Lien of this Agreement. Any Lender shall, upon any purchase, acquire good title to the property so purchased, to the extent permitted by applicable law, free of all rights of redemption.

(iii) In the event of any sale of the Collateral, or any part thereof, pursuant to any judgment or decree of any court or otherwise in connection with the enforcement of any of the terms of this Agreement, the unpaid principal amount of all Loans then outstanding, together with accrued interest thereon, and other amounts due thereunder, shall immediately become due and payable without presentment, demand, protest or notice, all of which are hereby waived.

(iv) Any sale of the Collateral or any part thereof or any interest therein, whether pursuant to foreclosure or power of sale or otherwise hereunder, shall forever be a bar against the Borrower or the relevant Lien Grantor, after the expiration of the period, if any, during which the Borrower or the Lien Grantor shall have the benefit of Section 7(a)(ii) hereof or any redemption laws which may not be waived.

If the Borrower shall for any reason fail to

execute and deliver such instruments and documents after such request by the Collateral Agent, the Collateral Agent may (i) obtain a judgment conferring on the Collateral Agent the right to immediate possession and requiring the Borrower to execute and deliver such instruments and documents to the Collateral Agent, to the entry of which judgment the Borrower hereby specifically consents to the fullest extent permitted by applicable law, and (ii) pursue all or part of such Collateral wherever it may be found and may enter any of the premises of the Borrower wherever such Collateral may be or be supposed to be and search for such Mortgaged Property and take possession of and remove such Mortgaged Property. All expenses of obtaining such judgment or of pursuing, searching for and taking such property shall, until paid, be secured by the Lien of this Agreement.

(ii) Upon every such taking of possession, the Collateral Agent may, from time to time, at the expense of the Collateral, make all such expenditures for maintenance, use, operation, storage, insurance, leasing, control, management, disposition, modifications or alterations to and of the Collateral, as it may deem proper. In each such case, the Collateral Agent shall have the right to maintain, use, operate, store, insure, lease, control, manage, dispose of, modify or alter the Collateral and to carry on the business and to exercise all rights and powers of the Borrower and/or the relevant Lien Grantors relating to the Collateral, as the Collateral Agent shall deem best, including the right to enter into any and all such agreements with respect to the maintenance, use, operation, storage, insurance, leasing, control, management, disposition, modification or alteration of the Mortgaged Property or any part thereof as the Collateral Agent may determine, and the Collateral Agent shall be entitled to collect and receive directly all tolls, rents, revenues, issues, income, products and profits of the Collateral and every part thereof, without prejudice, however, to the right of the Collateral Agent under any provision of this Agreement to collect and receive all cash held by, or required to be deposited with, the Collateral Agent hereunder. Such tolls, rents, revenues, issues, income, products and profits shall be applied to pay the expenses of the maintenance, use, operation, storage, insurance, leasing, control, management, disposition, improvement, modification or alteration of the Collateral and of conducting the business thereof, and to make all payments which the Collateral Agent may be required or may elect to make, if any, for taxes, assessments, insurance or other proper charges upon the Mortgaged Property or any part thereof (including the employment of engineers and accountants to examine, inspect and make reports upon the properties and books and records of the Borrower), and all other payments which the Collateral Agent may be required or authorized to make under any provision of this Agreement, as well as just and reasonable compensation for the services of the Collateral Agent, and of all persons properly engaged and employed by the Collateral Agent with respect hereto.

(c) Discontinuance of Proceedings. In case the Collateral Agent shall have instituted any proceeding to enforce any right, power or remedy under this Agreement by foreclosure, entry or otherwise, and such proceedings shall have been discontinued or abandoned for any reason or shall have been determined adversely to the Collateral Agent, then and in every such case the Borrower, the Lien Grantors and the Collateral Agent shall, subject to any determination in such proceedings, be restored to their former positions and rights hereunder with respect to the Collateral, and all rights, remedies and powers of the Borrower, the Lien Grantors or the Collateral Agent shall continue as if no such proceedings had been instituted.

(d) Appointment of Receiver. The Collateral Agent shall, as a matter of right, be entitled to the appointment of a receiver (who may be the Collateral Agent or any successor or nominee thereof) for all or any part of the Collateral, whether such receivership be incidental to a proposed sale of the Collateral or the taking of possession thereof or otherwise, and the Borrower hereby consents to the appointment of such a receiver and will not oppose any such appointment. Any receiver appointed for all or any part of the Collateral shall be entitled to exercise all the rights and powers of the Collateral Agent with respect to the Collateral.

Section 9. Application of Proceeds.

(a) If the Loans have been accelerated pursuant to Section 8 of the Senior Credit Agreement, the Collateral Agent may apply the proceeds of any sale or other disposition of all or any part of the Collateral, in the order of priorities:

first, to pay the expenses of such sale or other disposition, including reasonable compensation to agents of and counsel for the Collateral Agent, and all expenses, liabilities and advances incurred or made by the Collateral Agent in connection with the Security Documents, and any other amounts then due and payable to the Collateral Agent in connection with the Security Documents;

second, to pay ratably all interest (including Post-Petition Interest) and all facility and other fees and indemnity amounts payable in connection with the Senior Loans, until payment in full of all such interest and other fees and indemnity amounts shall have been made;

third, to pay the unpaid principal on the Senior Loans and all other Obligations (including in connection with Specified Hedge Agreements) in connection with the Senior Loans;

fourth, to pay ratably all interest (including Post-Petition Interest) and all facility and other fees and indemnity amounts payable in connection with the Junior Loans, until payment in full of all such interest and other fees and indemnity amounts shall have been made;

fifth, to pay the unpaid principal on the Junior Loans and pay all other Obligations in connection with the Junior Loans; and

finally, to pay to the relevant Lien Grantor, or as a court of competent jurisdiction may direct, any surplus then remaining from the proceeds of the Collateral owned by it;

provided that Collateral owned by a Lien Grantor and any proceeds thereof shall be applied pursuant to the foregoing clauses first, second, third, fourth and fifth only to the extent permitted by the limitation in Section 2(j). The Collateral Agent may make such distributions hereunder in cash or in kind or, on a ratable basis, in any combination thereof.

(b) In making the payments and allocations required by this Section 8, the Collateral Agent may rely upon information supplied to it pursuant to Section 12(g). All distributions made by the Collateral Agent pursuant to this Section 8 shall be final (except in the

event of manifest error) and the Collateral Agent shall have no duty to inquire as to the application by either Agent or any Lender of any amount distributed to it.

Section 10. Fees and Expenses; Indemnification. The Borrower will forthwith upon demand pay to the Collateral Agent:

(i) the amount of any Taxes that the Collateral Agent may have been required to pay by reason of the Liens created by the Security Documents or to free any Collateral from any other Lien thereon (other than Permitted Liens);

(ii) the amount of any and all reasonable out-of-pocket expenses, including transfer Taxes and reasonable fees and expenses of counsel and other experts, that the Collateral Agent may incur in connection with (x) the administration or enforcement of the Security Documents, including such expenses as are incurred to preserve the value of the Collateral or the validity, perfection, rank or value of any Lien created by the Security Documents, (y) the collection, sale or other disposition of any Collateral, or (z) the exercise by the Collateral Agent of any of its rights or powers under the Security Documents;

(iii) the amount of any fees that the Borrower shall have agreed in writing to pay to the Collateral Agent and that shall have become due and payable in accordance with such written agreement; and

(iv) the amount required to indemnify the Collateral Agent for, or hold it harmless and defend it against, any loss, liability or expense (including the reasonable fees and expenses of its counsel and any experts or sub-agents appointed by it hereunder) incurred or suffered by the Collateral Agent in connection with the Security Documents, except to the extent that such loss, liability or expense arises from the Collateral Agent’s gross negligence or willful misconduct or a breach of any duty of the Collateral Agent under this Agreement (after giving effect to Sections 11 and 12).

Any such amount not paid to the Collateral Agent on demand will bear interest for each day thereafter until paid at the highest rate of interest payable in connection with the Obligations under the Credit Agreements.

Section 11. Authority to Administer Collateral. Each Lien Grantor irrevocably appoints the Collateral Agent its true and lawful attorney, with full power of substitution, in the name of such Lien Grantor, any Lender or otherwise, for the sole use and benefit of the Lender, but at the Borrower’s expense, to the extent permitted by law to exercise, at any time and from time to time if the Loans have been accelerated pursuant to Section 8 of the Senior Credit Agreement, all or any of the following powers with respect to all or any of such Lien Grantor’s Collateral (to the extent necessary to pay the Obligations in full):

(a) to demand, sue for, collect, receive and give acquaintance for any and all monies due or to become due upon or by virtue thereof;

(b) to settle, compromise, compound, prosecute or defend any action or proceeding with respect thereto;

(c) to sell, lease, license or otherwise dispose of the same or the proceeds or avails thereof, as fully and effectually as if the Collateral Agent were the absolute owner thereof; and

(d) to extend the time of payment of any or all thereof and to make any allowance or other adjustment with reference thereto;

provided that, except in the case of Collateral that is perishable or threatens to decline speedily in value or is of a type customarily sold on a recognized market, the Collateral Agent will give the relevant Lien Grantor at least twenty days’ prior written notice of the time and place of any public sale thereof or the time after which any private sale or other intended disposition thereof will be made. The Collateral Agent and each Lien Grantor agree that such notice shall be considered to have been “sent within a reasonable time” pursuant to UCC Section 9-612. Such notice shall (i) contain the information specified in UCC Section 9-613, (ii) be Authenticated and (iii) be sent to the parties required to be notified pursuant to UCC Section 9-611(c); provided that, if the Collateral Agent fails to comply with this sentence in any respect, its liability for such failure shall be limited to the liability (if any) imposed on it as a matter of law under the UCC.

Section 12. Limitation on Duty in Respect of Collateral. Beyond the exercise of reasonable care in the custody and preservation thereof, the Collateral Agent will have no duty as to any Collateral in its possession or control or in the possession or control of any sub-agent or bailee or any income therefrom or as to the preservation of rights against prior parties or any other rights pertaining thereto. The Collateral Agent will be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession or control if such Collateral is accorded treatment substantially equal to that which it accords its own property, and will not be liable or responsible for any loss or damage to any Collateral, or for any diminution in the value thereof, by reason of any act or omission of any sub-agent or bailee selected by the Collateral Agent in good faith or by reason of any act or omission by the Collateral Agent pursuant to instructions from the Agents or the Lenders, except to the extent that such liability arises from the Collateral Agent’s gross negligence or willful misconduct.

Section 13. General Provisions Concerning the Collateral Agent.

(a) Authority. The Collateral Agent is authorized to take such actions and to exercise such powers as are delegated to the Collateral Agent by the terms of the Loan Agreements, together with such actions and powers as are reasonably incidental thereto.

(b) Coordination with Collateral Agent. The Collateral Agent will promptly notify each Agent of each notice or other communication received by the Collateral Agent hereunder and/or deliver a copy thereof to such Agent. As to any matters not expressly provided for herein (including (i) the timing and methods of realization upon the Collateral, and (ii) the exercise of any power that the Collateral Agent may, but is not expressly required to, exercise under any Security Document), the Collateral Agent shall act or refrain from acting other than in accordance with written instructions from the Agents or, in the absence of such instructions, in accordance with its discretion (subject to the following provisions of this Section 12).

(c) Rights and Powers as a Lender. The Person serving as the Collateral Agent shall, in its capacity as a Lender, have the same rights and powers as any other Lender and may exercise the same as though it were not the Collateral Agent. Such Person and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Borrower, any of its Subsidiaries or their respective Affiliates as if it were not the Collateral Agent hereunder.

(d) Limited Duties and Responsibilities. The Collateral Agent shall not have any duties or obligations under the Security Documents except those expressly set forth therein.

The Collateral Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Agents or in the absence of its own gross negligence or willful misconduct. The Collateral Agent shall not be responsible for the existence, genuineness or value of any Collateral or for the validity, perfection, priority or enforceability of any Lien, whether impaired by operation of law or by reason of any action or omission to act on its part under the Security Documents. The Collateral Agent shall be deemed not to have knowledge of any Event of Default unless and until written notice thereof is given to the Collateral Agent by the Borrower, any Subsidiary Guarantor, and Agent or a Lender, and the Collateral Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with any Security Document, (ii) the contents of any certificate, report or other document delivered thereunder or in connection therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth in any Security Document, (iv) the validity, enforceability, effectiveness or genuineness of any Security Document or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in any Security Document.

(e) Authority to Rely on Certain Writings, Statements and Advice. The Collateral Agent shall be entitled to rely on, and shall not incur any liability for relying on, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper Person. The Collateral Agent also may rely on any statement made to it orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon. The Collateral Agent may consult with legal counsel (who may be counsel for the Borrowers or any of their Subsidiaries), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountant or expert.

(f) Sub-Agents and Affiliates. The Collateral Agent may perform any of its duties and exercise any of its rights and powers through one or more sub-agents appointed by it. The Collateral Agent and any such sub-agent may perform any of its duties and exercise any of

its rights and powers through its Affiliates. The exculpatory provisions of Section 11 and this Section 12 shall apply to any such sub-agent and to the Affiliates of the Collateral Agent and any such sub-agent.

(g) Information as to Secured Guarantees and Actions by Lenders. For all purposes of the Security Documents, including determining the amounts of the Secured Guarantees or whether any action has been taken under any Security Document, the Collateral Agent will be entitled to rely on information from (i) the Agents, and actions taken by them, (ii) any Lender (or any trustee, agent or similar representative designated pursuant to subsection (f) to supply such information) for information as to its Secured Guarantees and actions taken by it, to the extent that the Collateral Agent has not obtained such information from the foregoing sources, and (iii) the Borrower or any Subsidiary Guarantor, to the extent that the Collateral Agent has not obtained information from the foregoing sources.

(h) Distribution of Notices. Within two Domestic Business Days after it receives or sends any notice referred to in this subsection, the Collateral Agent shall send each Agent copies of any notice given by the Collateral Agent to any Lien Grantor, or received by it from any Lien Grantor, pursuant to Section 7, 8, 10, 13(j) or 14.

(i) Refusal to Act. The Collateral Agent may refuse to act on any notice, consent, direction or instruction from either Agent or any agent, trustee or similar representative thereof that, in the Collateral Agent’s opinion, (i) is contrary to law or the provisions of any Security Document, (ii) may expose the Collateral Agent to liability (unless the Collateral Agent shall have been indemnified, to its reasonable satisfaction, for such liability by the Lender), or (iii) is unduly prejudicial to the Agent or Lenders not joining in such notice, consent, direction or instruction.

(j) Resignation; Successor Collateral Agent. Subject to the appointment and acceptance of a successor Collateral Agent as provided in this subsection, the Collateral Agent may resign at any time by notifying the Agents and the Borrower. Upon acceptance of its appointment as Collateral Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Collateral Agent hereunder, and the retiring Collateral Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrowers to a successor Collateral Agent shall be the same as those payable to its predecessor unless otherwise agreed by the Borrowers and such successor. After the Collateral Agent’s resignation hereunder, the provisions of Section 11 and this Section 12 shall continue in effect for the benefit of such retiring Collateral Agent, its sub-agents and their respective Affiliates in respect of any actions taken or omitted to be taken by any of them while the retiring Collateral Agent was acting as Collateral Agent.

Subject to Section 12(d), the Collateral Agent hereby agrees to be bound by the terms and provisions of all Loan Documents applicable to it.

Section 14. Termination of Liens; Release of Collateral.

all accrued and unpaid interest thereon, and any other Obligations payable under the Loan Documents and the reduction of all outstanding Commitments to zero.

(b) The Liens granted by a Subsidiary Guarantor under this Agreement shall terminate when its Secured Guarantee is released pursuant to Section 2(c).

(c) Upon any termination of a Lien granted under this Agreement or release of Collateral, the Collateral Agent will, at the expense of the Borrower or the relevant Subsidiary Guarantor, promptly execute and deliver to such Borrower or Subsidiary Guarantor such documents as such Borrower or Subsidiary Guarantor shall reasonably request to evidence the termination of such Lien or the release of such Collateral, as the case may be.

(d) The Borrower and any Subsidiary Guarantor may sell, exchange, assign or otherwise dispose of any of its Equipment or Inventory in the ordinary course of business unless (i) doing so would violate a covenant in the Credit Agreements or (ii) the Loans shall have been accelerated pursuant to Section 8 of the Senior Credit Agreement and the Collateral Agent shall have notified the Borrower or such Subsidiary Guarantor that its right to do so is terminated, suspended or otherwise limited. If such sale is to a Person which is not a Lien Grantor, then concurrently with any sale or other disposition permitted by the foregoing sentence, the Liens created by the Security Documents on the assets sold or disposed of will cease immediately without any action by the Collateral Agent or any Lender and the Collateral Agent will, at the expense of the Borrower or the relevant Subsidiary Guarantor, promptly execute and deliver to such Borrower or Subsidiary Guarantor such documents as such Borrower or Subsidiary Guarantor shall reasonably request to evidence the termination of such Lien on such assets.
