Any policies of insurance carried in accordance with this paragraph (a) and any policies taken out in substitution or replacement for any of such policies (A) shall be endorsed to name the Collateral Agent and each Lender (but without imposing on any such parties liability to pay the premiums for such insurance) (and, if any Lease shall be in effect, the Borrower in its capacity as lessor under the Lease) as additional insureds as their respective interests may appear, (B) shall provide that in respect of the interest of the Collateral Agent and each Lender (and, if any Lease shall be in effect, the Borrower in its capacity as lessor under the Lease) in such policies the insurance shall

not be invalidated by any action or inaction of the Borrower (or, if any Lease is then in effect, any Lessee) or any other Person and shall insure the Collateral Agent (and, if any Lease shall be in effect, the Borrower in its capacity as lessor under the Lease) regardless of any breach or violation of any warranty, declaration or condition contained in such policies by the Borrower (or, if any Lease is then in effect, any Lessee), (C) shall provide that, except to the extent not provided for by the Borrower’s war risk, hijacking and related perils insurance provider, if the Borrower maintains war risk, hijacking and related perils insurance, if the insurers cancel such insurance for any reason whatever or if any material change is made in such insurance which adversely affects the interest of the Collateral Agent or any Lender (or, if any Lease shall be in effect, the Borrower in its capacity as lessor under the Lease), or such insurance shall lapse for non-payment of premium, such cancellation, lapse or change shall not be effective as to the Collateral Agent or such Lender (or, if any Lease shall be in effect, the Borrower in its capacity as lessor under the Lease) for thirty (30) days (seven (7) days in the case of war risk and allied perils coverage) after issuance to the Collateral Agent and each Lender (or, if any Lease shall be in effect, the Borrower in its capacity as lessor under the Lease), respectively, of written notice by such insurers of such cancellation, lapse or change; provided, however, that if any notice period specified above is not reasonably obtainable, such policies shall provide for as long a period of prior notice as shall then be reasonably obtainable, (D) shall be primary without right of contribution from any other insurance which is carried by the Collateral Agent or any Lender (or, if any Lease shall be in effect, the Borrower in its capacity as lessor under the Lease), (E) shall expressly provide that all of the provisions thereof, except the limits of liability, shall operate in the same manner as if there were a separate policy covering each insured, and (F) shall waive any right of the insurers to any set-off or counterclaim or any other deduction, whether by attachment or otherwise, in respect of any liability of the Collateral Agent or any Lender (or, if any Lease shall be in effect, the Borrower in its capacity as lessor under the Lease) to the extent of any moneys due to the Collateral Agent or any Lender (or, if any Lease shall be in effect, the Borrower in its capacity as lessor under the Lease). To the extent that the Borrower maintains war risk, hijacking and related perils liability insurance and the Borrower’s war risk, hijacking and related perils liability insurance provider does not provide for provision of direct notice to the Collateral Agent and each Lender of cancellation, material change or lapse in the insurance required hereunder, the Borrower hereby agrees that upon receipt of notice of any thereof from such insurance provider it shall give the Collateral Agent and each Lender immediate notice of each cancellation or lapse of, or material change to, such insurance.

(II) During any period that an Aircraft or Engine is on the ground and not in operation, the Borrower may carry or cause to be carried, in lieu of the insurance required by clause (I) above, insurance otherwise conforming with the provisions of said clause (I) except that (A) the amounts of coverage shall not be required to exceed the amounts of liability insurance from time to time applicable to aircraft or engines owned or operated by the Borrower of the same type as such Aircraft or Engine which are on the ground and not in operation; and (B) the scope of the risks covered and the type of insurance shall be the same as from time to time shall be applicable to aircraft or engines owned or operated by the Borrower of the same type which are on the ground and not in operation.

(b) Insurance Against Loss or Damage to the Aircraft and Engines. (I) Except as provided in clause (II) of this Section 2.07(b), the Borrower shall maintain or cause

to be maintained in effect, at its or any Lessee’s expense, with insurers of recognized responsibility, (A) all-risk ground and flight aircraft hull insurance covering each Aircraft and Engine, (B) all-risk ground - coverage of the Engines while removed from each Aircraft and replaced by similar components and (C) all risk property damage insurance covering the Aircraft and Engines (including, without limitation, with respect to any Aircraft or Engine, war risk and governmental confiscation and expropriation (other than by the government of registry of such Aircraft) and hijacking insurance (with such limitations as are customary in the industry)(collectively, “Hull War Risk Insurance”), if and to the extent the same is maintained by the Borrower (or, if a Lease is then in effect, by Lessee) with respect to other aircraft or engines owned or operated by the Borrower (or such Lessee) on the same routes as such Aircraft or Engine is operated, except that the Borrower (or such Lessee) shall maintain Hull War Risk Insurance if such Aircraft is operated on routes where the custom is for major international air carriers flying comparable routes to carry such insurance) which is of the type as from time to time applicable to aircraft or engines owned or operated by the Borrower (or, if a Lease is then in effect, by Lessee) of the same type as such Aircraft or Engine; provided that such insurance shall at all times while any Aircraft, or any Engine is subject to this Security Agreement be for an amount (subject to self-insurance to the extent permitted by Section 2.07(d)) not less than 105% of the allocable contribution of such Aircraft and Engine to the Borrowing Base, subject to standard deductibles. Any policies carried in accordance with this paragraph (b) covering the Aircraft and Engines, and any policies taken out in substitution or replacement for any such policies (i) shall name the Collateral Agent (and, if any Lease shall be in effect, the Borrower in its capacity as lessor under the Lease) as an additional insured, as its interest may appear (but without imposing on such party liability to pay premiums with respect to such insurance), (ii) shall provide that all proceeds with respect to a Recovery Event shall be payable to the Collateral Agent for application pursuant to Section 2.11 of the Senior Credit Agreement, (iii) shall provide that if the insurers cancel such insurance for any reason whatever, or such insurance lapses for non-payment of premium or if any material change is made in the insurance which adversely affects the interest of the Collateral Agent, such cancellation, lapse or change shall not be effective as to the Collateral Agent (or, if any Lease shall be in effect, the Borrower in its capacity as lessor under the Lease) for thirty (30) days (seven (7) days in the case of Hull War Risk Insurance coverage) after issuance to the Collateral Agent and each Lender (or, if any Lease shall be in effect, the Borrower in its capacity as lessor under the Lease), respectively, of written notice by such insurers of such cancellation, lapse or change, provided, however, that if any notice period specified above is not reasonably obtainable, such policies shall provide for as long a period of prior notice as shall then be reasonably obtainable, (iv) shall provide that in respect of the interest of the Collateral Agent and each Lender (and, if any Lease shall be in effect, the Borrower in its capacity as lessor under the Lease) in such policies the insurance shall not be invalidated by any action or inaction of the Borrower (or, if a Lease is then in effect, any Lessee) or any other Person and shall insure the Collateral Agent (and, if any Lease shall be in effect, the Borrower in its capacity as lessor under the Lease) regardless of any breach or violation of any warranty, declaration or condition contained in such policies by the Borrower (or, if a Lease is then in effect, any Lessee), (v) shall waive any right of subrogation of the insurers against the Collateral Agent and each Lender (and, if any Lease shall be in effect, the Borrower in its capacity as lessor under the Lease), and (vi) shall waive any right of the insurers to set-off or counterclaim or any other deduction, whether by attachment or otherwise, in respect

of any liability of the Collateral Agent or the Borrower (or any Lessee) to the extent of any moneys due to the Collateral Agent. To the extent that the Borrower maintains Hull War Risk Insurance and the Borrower’s Hull War Risk Insurance provider does not provide for provision of direct notice to the Collateral Agent and each Lender of cancellation, material change or lapse in the insurance required hereunder, the Borrower hereby agrees that upon receipt of notice of any thereof from such insurance provider it shall give the Collateral Agent and each Lender immediate notice of each cancellation or lapse of, or material change to, such insurance. In the case of a loss with respect to an engine (other than an Engine) installed on an Airframe, the Collateral Agent shall hold any payment to it of any insurance proceeds in respect of such loss for the account of any third party that is entitled to receive such proceeds.

As between the Collateral Agent and the Borrower, the insurance payments for any property damage loss to any Airframe or Engine not constituting a Recovery Event with respect thereto will be applied in payment for repairs or for replacement property in accordance with the terms of Sections 2.05 and 2.06, if not already paid for by the Borrower (or any Lessee or insurer), and any balance (or if already paid for by the Borrower (or any Lessee), all such insurance proceeds) remaining after compliance with such Sections with respect to such loss shall be paid to the Borrower (or any Lessee if directed by the Borrower).

(II) During any period that an Aircraft or Engine is on the ground and not in operation, the Borrower may carry or cause to be carried, in lieu of the insurance required by clause (I) above, insurance otherwise conforming with the provisions of said clause (I) except that the scope of the risks and the type of insurance shall be the same as from time to time applicable to aircraft or engines owned or operated by the Borrower (or, if a Lease is then in effect, by Lessee) of the same type similarly on the ground and not in operation, provided that the Borrower shall maintain insurance against risk of loss or damage to such Aircraft or Engine in an amount equal 105% of the allocable contribution of such Aircraft or Engine to the Borrowing Base, subject to a standard deductible.

(c) Reports, etc. The Borrower will furnish, or cause to be furnished, to the Collateral Agent and each Lender, on or before the Closing Date and on or before April 1 in each year thereafter commencing April 1, 2007, a certificate of insurance in respect to aircraft and engines not on lease signed by Willis Limited on behalf of the insurers or any other independent firm of insurance brokers reasonably acceptable to the Collateral Agent (the “Insurance Brokers”), describing in reasonable detail the insurance and, if applicable, reinsurance then carried and maintained with respect to the Eligible Equipment. The Borrower will cause such Insurance Brokers to agree to advise the Collateral Agent and each Lender in writing of any default in the payment of any premium. To the extent such agreement is reasonably obtainable, the Borrower will also cause such Insurance Brokers to agree to advise the Collateral Agent and each Lender in writing at least thirty (30) days (seven (7) days in the case of commercial war risk and allied perils coverage), prior to the expiration or termination date of any commercial insurance carried and maintained on any Eligible Equipment pursuant to this Section 2.07; provided that, in respect of any commercial War Risk Insurance, if the notice period specified above is not obtainable, the Insurance Brokers shall provide for as long a period of notice as shall then be obtainable. In addition, the Borrower will also cause such Insurance Brokers to deliver to the Collateral Agent and each Lender, on or prior to the date of expiration of any commercial

insurance policy referenced in a previously delivered certificate of insurance, a new certificate of insurance, substantially in the same form as delivered by the Borrower to such party on the Closing Date. In the event that the Borrower or any Lessee shall fail to maintain or cause to be maintained insurance as herein provided, the Collateral Agent or any Lender may at its sole option provide such insurance and, in such event, the Borrower shall, upon demand, reimburse the Collateral Agent or such Lender for the cost thereof to Collateral Agent or such Lender, without waiver of any other rights Collateral Agent or such Lender may have. The Collateral Agent agrees that endorsements in accordance with AVN67B shall be acceptable.

(d) In addition the Borrower will provide a report signed by Willis Aviation Consulting Limited or any other independent firm of insurance advisers reasonably acceptable to the Collateral Agent (the “Insurance Advisers”) stating the opinion of such firm that the insurance then carried by the Borrower or any Lessee and maintained with respect to the Eligible Equipment complies with the terms hereof; provided, however, (i) in the case of War Risk Insurance acquired by the Borrower directly from the FAA or other instrumentality of the United States, no opinion concerning such coverage, other than the fact that the Borrower has acquired it, need be given and (ii) that all information contained in the foregoing report shall not be made available by the Collateral Agent or the Lender to anyone except (A) to permitted transferees of the Lender or the Collateral Agent who agree to hold such information confidential, (B) to the Lender’s or the Collateral Agent’s counsel or independent certified public accountants or independent insurance advisors who agree to hold such information confidential, (C) as may be required by any statute, court or administrative order or decree or governmental ruling or regulation or (D) to bank examiners and auditors.

(e) Additional Insurance by the Borrower. The Borrower (and any Lessee) may at its own expense carry insurance with respect to its interest in the Eligible Equipment in amounts in excess of that required to be maintained by this Section 2.07.

(f) Indemnification by Government in Lieu of Insurance. Notwithstanding any provisions of this Section 2.07 requiring insurance, the Collateral Agent agrees to accept, in lieu of insurance against any risk with respect to the Eligible Equipment, indemnification from, or insurance provided by, the United States Government or any agency or instrumentality thereof or, in the case of an Aircraft, upon the written consent of the Collateral Agent, other Country of Registration of such Aircraft or any agency or instrumentality thereof, against such risk in an amount which, when added to the amount of insurance against such risk maintained by the Borrower (or any Lessee) with respect to the Eligible Equipment (including permitted self-insurance) shall be at least equal to the amount of insurance against such risk otherwise required by this Section 2.07. The Borrower shall furnish (including by e-mail distribution) in advance of attachment of such indemnity or insurance (or any renewal thereof), if practical to do so or as soon thereafter as is practicable, copies of any certificates of insurance evidencing any such indemnity or insurance, together with such evidence as shall be required thereunder to cause the additional insureds/loss payee hereunder to be named as additional insureds thereunder.

(g) Aircraft and Engines being Parted Out. Aircraft and engines which are both (i) on the ground and not in operation and (ii) either being disassembled for parts or held on

consignment shall not be “Aircraft” or “Engines” for which insurance is required to be obtained under this Section 2.07.

(h) Aircraft and/or Engines on Lease on Closing Date. As soon as practicable after the Closing Date, the Borrower shall cause each Lessee of Aircraft Asset Leases in effect on the Closing Date to revise the insurance maintained pursuant to such Aircraft Asset Leases to provide for the endorsements in favor of the Collateral Agent and the Lenders required by this Section 2.07. So long as the Borrower shall use all commercially reasonable efforts to obtain such endorsements, the Borrower shall not be deemed in default of its obligations hereunder as a result of the insurance being maintained by such Lessee of a Aircraft Asset Lease entered into prior to the Closing Date not providing for the endorsements in favor of the Collateral Agent required by this Section 2.07.

Section 2.08. Inspection.

At all reasonable times and upon at least 15 Business Days prior written notice to the Borrower, the Collateral Agent acting on behalf of all of the Lenders, and their authorized representatives may inspect the Aircraft and the Engines in Borrower’s or any Subsidiary Guarantor’s possession and inspect and make copies (at the Collateral Agent’s expense unless an Event of Default shall be continuing, in which case it shall be at the Borrower’s expense) of the books and records of the Borrower or any Subsidiary Guarantor or any Trust relating to the maintenance of the Aircraft and the Engines upon reasonable notice and at any time during normal business hours and not more than once during any fiscal quarter (unless an Event of Default shall have occurred and be continuing). The Collateral Agent shall not have any duty to make any such inspection nor shall it incur any liability or obligation by reason of not making such inspection. To the extent any Aircraft or Engine is subject to an Aircraft Asset Lease, the Borrower shall (or shall cause the applicable Subsidiary Guarantor of Trust) to exercise the inspection rights set forth in such Aircraft Asset Lease at the reasonable request of the Collateral Agent not more than once during any fiscal quarter (unless an Event of Default shall have occurred and be continuing) to the extent permitted under such Aircraft Asset Lease.

Section 2.09. Requisition, etc.

In the event of the requisition for use by any government, or any instrumentality or agency thereof, of an Airframe or an Engine, so long as such Airframe or Engine is subject to the Lien of this Security Agreement, the Borrower shall promptly notify the Collateral Agent of such requisition, and all of the Borrower’s obligations under this Security Agreement with respect thereto, shall continue to the same extent as if such requisition had not occurred. All payments received by the Collateral Agent or the Borrower from such government or instrumentality or agency thereof for the use of such Airframe and Engines shall be paid over to, or retained by, the Borrower (or, if directed by the Borrower, any Lessee).

Section 2.10. Status of Lease Default Equipment and Impaired Aircraft Assets.

Any failure of the Borrower, any Subsidiary Guarantor or any Trust to perform or observe any covenant, condition, agreement or any error in a representation or warranty under

this Agreement or any other Loan Agreement shall not constitute a default hereunder or any other Loan Document or a Default or Event of Default under the Credit Agreements to the extent such failure or error is caused solely by reason of an event that causes an Aircraft Asset to be Lease Default Equipment or an Impaired Aircraft Asset, so long as the Borrower is complying with its obligations under Section 2.9(d) of the Senior Credit Agreement and, unless such Aircraft Asset has a Borrowing Base Value of zero, is exercising all commercially reasonable efforts to correct or remedy such event.

ARTICLE III

(i) cause the Borrower or the relevant Subsidiary Guarantor or Trust upon the written demand of the Collateral Agent and at the Borrower’s or the relevant Subsidiary Guarantor’s expense, to deliver promptly, and the Borrower shall deliver promptly, the Collateral (or any portion thereof) as the Collateral Agent may so demand to the Collateral Agent, or the Collateral Agent, at its option, may enter upon the premises where all or any part of the Collateral is located and take immediate possession (to the exclusion of the Borrower or the relevant Subsidiary Guarantor or Trust and all Persons claiming under or through the Borrower or the relevant Subsidiary Guarantor or Trust) of and remove the same by summary proceedings;

(ii) subject to the notice specified in Section 6.01, sell the Collateral (or any portion thereof) at public or private sale, whether or not the Collateral Agent shall at the time have possession thereof, as the Collateral Agent may determine, or lease or otherwise dispose of, all or any part of any Airframe, any Engine or any Inventory as the Collateral Agent, in its sole discretion, may determine, all free and clear of any rights of the Borrower or the relevant Subsidiary Guarantor or Trust, except as hereinafter set forth in this Article III; provided, however, that the Borrower or the relevant Subsidiary Guarantor or Trust shall be entitled at any time prior to any such disposition to redeem the Collateral by paying in full all of the Obligations; or

(iii) 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.

(c) 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 Security 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.

(d) 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 Subsidiary Guarantor, after the expiration of the period, if any, during which the Borrower or the Subsidiary Guarantor or Trust shall have the benefit of Section 3.01(a)(ii) hereof or any redemption laws which may not be waived.

(e) Any sale or other conveyance of the Collateral by the Collateral Agent made pursuant to the terms of this Security Agreement shall bind the Lenders and the Borrower and the relevant Subsidiary Guarantors and Trusts and shall be effective to transfer or convey all right, title and interest of the Borrower and the relevant Subsidiary Guarantors. No purchaser or other grantee shall be required to inquire as to the authorization, necessity, expediency or regularity of such sale or conveyance or as to the application of any sale or other proceeds with respect thereto by the Collateral Agent.

Section 3.02. Return of Equipment, Etc.

(a) If the Loans have been accelerated pursuant to Section 8 of the Senior Credit Agreement, at the request of the Collateral Agent, the Borrower and/or the relevant Subsidiary Guarantors and/or Trusts shall promptly execute and deliver to the Collateral Agent such instruments of title and other documents as the Collateral Agent may deem necessary or advisable to enable the Collateral Agent or an agent or representative designated by the Collateral Agent, at such time or times and place or places as the Collateral Agent may specify, to obtain possession of all or any part of the Collateral to which the Collateral Agent shall at the time be entitled hereunder. 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 Collateral and take possession of and remove such Collateral.

(b) 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 Subsidiary Guarantors and/or Trusts 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 Collateral 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 Security Agreement to collect and receive all cash held by, or required to be deposited with, the Collateral Agent hereunder.

Section 3.03. Discontinuance of Proceedings. In case the Collateral Agent shall have instituted any proceeding to enforce any right, power or remedy under this Security 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 Subsidiary Guarantors, the Trusts 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 Subsidiary Guarantors, the Trusts or the Collateral Agent shall continue as if no such proceedings had been instituted.

Section 3.04. 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.

ARTICLE IV

(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.

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 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.

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 Article VII and this Article VIII 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) 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.

(i) 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 Article VII and this Article VIII 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.

(j) Subject to 8.01(d), the Collateral Agent hereby agrees to be bound by the terms and provisions of all Loan Documents applicable to it.

ARTICLE IX

TERMINATION OF LIENS; RELEASE OF COLLATERAL

Section 9.01. Termination Of Liens; Release Of Collateral.

(a) The Liens granted by the Borrower, the Subsidiary Guarantors and the Trusts under this Agreement shall terminate upon the payment in full of the unpaid principal amount of all Loans, 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 and any Trust in which it is the beneficiary under this Agreement shall terminate when its Secured Guarantee is released pursuant to Section 2(c) of the Guarantee and Collateral Agreement.

(c) Upon any termination of a Lien granted under a Security Document or release of Collateral, the Collateral Agent will, at the expense of the Borrower or the relevant Subsidiary Guarantor or Trust, promptly execute and deliver to such Borrower or Subsidiary Guarantor or Trust (or its designee) such documents as such Borrower or Subsidiary Guarantor or Trust 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 the Aircraft or Engines 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 the Borrower or one of its Subsidiaries, 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.
