(iii) any judicial or nonjudicial foreclosure or sale of, or other election of remedies with respect to, any interest in any Collateral serving as security for all or any part of the Secured Obligations, even though such foreclosure, sale or election of remedies may impair the subrogation rights of Airlines may preclude Airlines from obtaining reimbursement, contribution, indemnification or other recovery from any other Person and even though Airlines may not, as a result of such foreclosure, sale or election of remedies, be liable for any deficiency;

(iv) any act or omission of Collateral Agent or any other Person (other than payment or performance of the Secured Obligations) that directly or indirectly results in or aids the discharge or release of Airlines or any part of the Secured Obligations or any security or guarantee (including any letter of credit) for all or any part of the Secured Obligations by operation of law or otherwise;

Upon Default and in addition to the remedies noted above, the Collateral Agent may, to the fullest extent permitted by applicable Law, employ the following specific

(vi) transfer (or permit any Permitted Lessee to transfer) possession of any Spare Engine to the U.S. Government, so long as Airlines (or any Permitted Lessee) shall promptly notify the Collateral Agent in writing thereof and, in the case of a transfer pursuant to the Civil Reserve Air Fleet Program, provide the Collateral Agent with the name and address of the Contracting Office Representative for the Air Mobility Command of the United States Air Force or other appropriate person to whom notice must be given pursuant to Section 6.13 and to whom requests or claims must be made to the extent applicable under the Civil Reserve Airfleet Program;

(vii) enter into a Wet Lease with respect to an Aircraft to which a Spare Engine is attached, provided that Airlines’ obligations hereunder shall continue in full force and effect notwithstanding any such Wet Lease; or

(viii) so long as no Event of Default shall have occurred and be continuing, and subject to the provisions of the immediately following paragraph, Airlines may, at any time, enter into a lease with respect to any Spare Engine with any Permitted Lessee, provided, (1) any such Permitted Lease: (x) shall include provisions for the maintenance, operation, possession and insurance of the Aircraft that are the same in all material respects as the applicable provisions of this Agreement, (y) shall provide that such Permitted Lessee may not further sublease the Spare Engine subject thereto, and (z) shall not permit the Permitted Lessee to take any action with respect to the Spare Engine subject thereto that Airlines is not permitted to take under this Agreement; and (2) in the case of a Permitted Lessee that is located in a country other than the United States, that the United States maintains normal diplomatic relations with the country in which such Permitted Lessee is principally based at the time such lease is entered into, and the Collateral Agent shall receive, at Airlines’ expense, at the time such lease is entered into an opinion of counsel reasonably satisfactory to the Collateral Agent to the effect that (v) the terms of the proposed lease will be legal, valid, binding and (subject to customary exceptions) enforceable against the proposed Permitted Lessee in the country in which the proposed Permitted Lessee is principally based, including, without limitation, those terms of the lease stating that it is subject and subordinate to this Agreement, (w) it is not necessary for the Collateral Agent to register or qualify to do business in such country, if not already so registered or qualified, as a result of such lease, (x) the laws of the country in which such proposed Permitted Lessee is principally based require fair compensation by the government of such jurisdiction payable in currency freely convertible into Dollars for the loss of title of such Spare Engine in the event of the requisition by such government of such title, (y) the laws of the country in which such proposed Permitted Lessee is principally based would give recognition to the Lien of this Agreement and the priority thereof as a first priority perfected Lien (subject to Permitted Liens) in a bankruptcy or insolvency of such Permitted Lessee and there exist no possessory rights in favor of the lessee under the laws of such lessee’s country which would, upon bankruptcy or insolvency of or other default by Airlines, and assuming at such time such lessee is not insolvent or bankrupt, prevent the taking of possession of any such Spare Engine by the Collateral Agent in accordance with and when permitted by the terms hereof upon the exercise by the Collateral Agent of its remedies hereunder and (z) the agreement of such Permitted Lessee that its rights under the lease are subject and subordinate to all the terms of this Agreement is enforceable against such Permitted Lessee under applicable law (subject to customary exceptions).

The rights of any Permitted Lessee or other transferee who receives possession of a Spare Engine by reason of a transfer permitted by this Section 5.02(e) (other than the transfer of a Spare Engine which is deemed an Event of Loss) shall be subject and subordinate to, and any Permitted Lease shall contain a provision pursuant to which the Permitted

Lessee expressly acknowledges that its leasehold interest is subject and subordinate to, all the terms of this Agreement, including the rights of the Collateral Agent to repossess such Spare Engine and avoid such lease in the exercise of its rights to repossession of the Spare Engines under this Agreement, and Airlines shall remain primarily liable for the performance and observance of all of the terms of this Agreement and all the terms and conditions of this Agreement and the other Operative Agreements shall remain in effect, in each case to the same extent as if such lease or transfer had not occurred. Except as otherwise provided herein and without in any way relieving Airlines from its primary obligation for the performance of its obligations under this Agreement, Airlines may in its sole discretion permit a Permitted Lessee to exercise any or all rights which Airlines would be entitled to exercise under Article V, and may cause a Permitted Lessee to perform any or all of Airlines’ obligations under Article V (other than the right to lease a Spare Engine), and the Collateral Agent agrees to accept actual and full performance thereof by a Permitted Lessee in lieu of performance by Airlines. No pooling agreement, permitted lease or other relinquishment of possession of any Spare Engine shall in any way discharge or diminish any of Airlines’ obligations under this Agreement or constitute a waiver by the Collateral Agent of any rights or remedies hereunder.

Section 5.03 Permitted Sale or Dispositions of Pledged Spare Parts; Spare Engine Exchange.

(a) So long as no Event of Default has occurred and is continuing and subject to the terms of Section 5.07, Airlines may sell, transfer or dispose of Pledged Spare Parts and Pledged Spare Engines free from the Lien of this Agreement.

(b) No purchaser in good faith of property purporting to be transferred pursuant to Section 5.02(a)(ii) or Section 5.04(a) shall be bound to ascertain or inquire into the authority of Airlines to make any such transfer, free and clear of the Lien of this Agreement. Any instrument of transfer executed by the Company under Section 5.02(a)(ii) or Section 5.03 shall be sufficient for the purposes of this Agreement and shall constitute a good and valid release, assignment and transfer of the property therein described free from the Lien of this Agreement.

(c) Upon not less than five Business Days’ prior written notice from Airlines to the Collateral Agent, the Collateral Agent (so long as no Event of Default shall have occurred and be continuing) shall release from the Lien of this Agreement pursuant to Section 6.01 one or more Pledged Spare Engines specified in such notice upon Airlines replacing such Pledged Spare Engines with other Qualified Spare Engines.

Section 5.04 Insurance.

(a) The Company’s Obligation to Insure.

(i) Airlines shall comply with, or cause to be complied with, each of the provisions of Annex 2, which provisions are hereby incorporated by this reference as if set forth in full herein provided, however, that if any policy of insurance described in Annex 2 is not available or is not available on commercially reasonable terms then Airlines shall not be required to obtain or maintain such policy of insurance.

(ii) Airlines may provide, in lieu of insurance against any risk with respect to any Pledged Spare Engine, indemnification from, or insurance provided by, the United States Government, against such risk in an amount that, when added to the amount of insurance (including permitted self-insurance), if any, against such risk that Airlines (or any Permitted Lessee) may continue to maintain, in accordance with this Section 5.04(a), shall be at least equal to the amount of insurance against such risk otherwise required by this Section 5.04(a).

(iii) Nothing in this Section 5.04(a) shall limit or prohibit (a) the Company or Airlines from maintaining the policies of insurance required under Annex 2 with higher limits than those specified in Annex 2, or (b) the Collateral Agent or any Additional Insured from obtaining insurance for its own account (and any proceeds payable under such separate insurance shall be payable as provided in the policy relating thereto); provided, however, that no insurance may be obtained or maintained that would limit or otherwise adversely affect the coverage of any insurance required to be obtained or maintained by Airlines pursuant to this Section 5.04(a) and Annex 2.

(b) Application of Insurance Proceeds.

(i) As between Airlines and the Collateral Agent, all insurance proceeds paid under policies required to be maintained by Airlines pursuant to this Agreement as a result of the occurrence of an Event of Loss with respect to any Pledged Spare Parts involving proceeds in excess of the Threshold Amount will be paid to the Collateral Agent. At any time or from time to time after the receipt by the Collateral Agent of any such insurance proceeds, upon submission to the Collateral Agent of an Officer’s Certificate stating that Airlines has after the occurrence of such Event of Loss purchased additional Qualified Spare Parts that are located at or have been shipped by vendor(s) to a Designated Location, and stating the aggregate purchase price for such additional Qualified Spare Parts, the Collateral Agent shall pay the amount of such purchase price, up to the amount of such insurance proceeds not previously disbursed pursuant to this sentence or otherwise distributed under this Agreement, to Airlines or its designee.

(ii) As between Airlines and the Collateral Agent, all insurance proceeds paid under policies required to be maintained by Airlines pursuant to this Agreement as a result of the occurrence of an Event of Loss with respect to any Pledged Spare Engines involving proceeds in excess of the Threshold Amount will be paid to the Collateral Agent. At any time or from time to time after the receipt by the Collateral Agent of any such insurance proceeds, upon submission to the Collateral Agent of an Officer’s Certificate stating that Airlines has after the occurrence of such Event of Loss purchased additional Qualified Spare Engines, and stating the aggregate purchase price for such additional

Qualified Spare Engines, the Collateral Agent shall pay the amount of such purchase price, up to the amount of such insurance proceeds not previously disbursed pursuant to this sentence or otherwise distributed under this Agreement, to Airlines or its designee.

(iii) All proceeds of insurance required to be maintained by Airlines in accordance with this Agreement in respect of any property damage or loss involving proceeds of the Threshold Amount or less or not constituting an Event of Loss with respect to any Pledged Spare Parts or Pledged Spare Engines and insurance proceeds in excess of the Secured Obligations shall be paid over to, and retained by, Airlines.

(iv) If either the Collateral Agent or Airlines receives a payment of such insurance proceeds in excess of its entitlement pursuant to this Agreement, it shall promptly pay such excess to the other.

(c) Application of Insurance Proceeds and Certain Other Amounts During Existence of an Event of Default. Any insurance proceeds or other amounts described in this Section 5.04 that is payable or creditable to, or retainable by, the Airlines shall not be paid or credited to, or retained by, Airlines if at the time such payment, credit or retention would otherwise occur an Event of Default shall have occurred and be continuing, but shall instead be held by or paid over to the Collateral Agent as security for the obligations of Airlines under this Agreement. At such time as there shall not be continuing any Event of Default, such amount and any gains thereon shall be paid to Airlines to the extent not previously applied in accordance with this Agreement.

Section 5.05 Liens. Airlines will not directly or indirectly create, incur, assume or suffer to exist any Lien on or with respect to the Collateral, title to any of the foregoing or any interest of the Airlines therein, except Permitted Liens. Airlines shall promptly, at its own expense, take such action as may be necessary to duly discharge (by bonding or otherwise) any such Lien other than a Permitted Lien arising at any time.

Section 5.06 Certain Assurances.

(a) Airlines shall duly execute, acknowledge and deliver, or shall cause to be executed, acknowledged and delivered, all such further agreements, instruments, certificates or documents, and shall do and cause to be done such further acts and things, in any case, as Collateral Agent shall reasonably request for accomplishing the purposes of this Agreement, provided that any instrument or other document so executed by Airlines will not expand any obligations or limit any rights of Airlines in respect of the transactions contemplated by any Operative Agreement.

(b) Airlines shall promptly take such action with respect to the recording, filing, re-recording and refiling of this Agreement and any amendments or supplements hereto, as shall be necessary to continue the perfection and priority of the Liens created by this Agreement.

Section 5.07 Collateral Requirements.

(a) Airlines agrees that it will not permit (i) the Pledged Spare Parts Collateral Ratio to be greater than the Pledged Spare Parts Maximum Collateral Ratio, or (ii) the Pledged Spare Engines Collateral Ratio to be greater than the Pledged Spare Engines Maximum Collateral Ratio. If either such Collateral Ratio, as most recently determined pursuant to an Independent Appraiser’s Certificate, is greater than the applicable Maximum Collateral Ratio, Airlines shall, within 90 days after the date of the Independent Appraiser’s Certificate setting forth the calculation of such Collateral Ratio:

(i) subject (A) additional Qualified Spare Parts (the “Additional Parts”) to the Lien of this Agreement in accordance with Section 5.07(b) (in the event that the Pledged Spare Parts Collateral Ratio is greater than the Pledged Spare Parts Maximum Collateral Ratio), and/or (B) subject additional Qualified Spare Engines (“Additional Spare Engines”) to the Lien of this Agreement in accordance with Section 5.07(b) (in the event the Pledged Spare Engines Collateral Ratio is greater than the Pledged Spare Engines Maximum Collateral Ratio);

(ii) grant a security interest to the Collateral Agent in other property to secure the Secured Obligations for the benefit of the Securityholders;

(iii) provide a security interest in Cash Collateral to the Collateral Agent to secure the Secured Obligations for the benefit of the Securityholders;

(iv) redeem some or all of the Notes pursuant to Article III of the Indenture; or

(v) any combination of the foregoing;

such that, the Collateral Ratios, as recalculated giving effect to such action taken pursuant to this Section 5.07 and, in the case of clauses (i), (ii) and (iii) of this Section 5.07, using the Fair Market Value of any such additional Collateral determined pursuant to Section 5.07(c) (but otherwise using the information used to determine the Collateral Ratios as most recently determined) would not be greater than Maximum Collateral Ratios.

(b) In order to comply with Section 5.07(a)(i)(A) by subjecting Additional Parts to the Lien of this Agreement, Airlines shall (i) add one or more locations as Designated Locations by delivering to the Collateral Agent a supplement to this Agreement identifying such additional Designated Locations, in which case the Qualified Spare Parts at such new Designated Locations, to the extent not previously included in the Pledged Spare Parts, shall be deemed Pledged Spare Parts and/or (ii) add to a Designated Location Qualified Spare Parts that were not previously included as Pledged Spare Parts, which shall then be deemed Pledged Spare Parts.

(c) In order to comply with Section 5.07(a)(i)(B) by subjecting Additional Spare Engines to the Lien of this Agreement, Airlines shall add one or more

Additional Spare Engines to the Lien of this Agreement by delivering to the Collateral Agent a supplement to this Agreement identifying such Additional Spare Engines, in which case such Additional Spare Engines shall be deemed Pledged Spare Engines.

(d) In connection with the provision of additional Collateral pursuant to Section 5.07(a) or (c), Airlines shall furnish to the Collateral Agent an Independent Appraiser’s Certificate signed by an Independent Appraiser stating, in the opinion of such Independent Appraiser, the Fair Market Value of such additional Collateral, as of a date not earlier than 60 days prior to the date of such Independent Appraiser’s Certificate.

(e) At all reasonable times, the Collateral Agent and its authorized representatives (the “Inspecting Parties”) may (not more than once every 12 months unless an Event of Default has occurred and is continuing, in which case such inspection right shall not be so limited) inspect the Pledged Spare Parts (including without limitation, the Spare Parts Documents) and the Pledged Spare Engines (including the Spare Engines Documents). Any inspection of the Pledged Spare Parts and the Pledged Spare Engines hereunder shall be limited to a visual inspection and shall not include the disassembling, or opening of any components, of any Pledged Spare Part and the Pledged Spare Engines, and such inspection shall be conducted so as not to interfere with Airlines’ or any Permitted Lessee’s maintenance and use of the Pledged Spare Parts and the Pledged Spare Engines. With respect to such rights of inspection, the Collateral Agent shall not have any duty or liability to make, or any duty or liability by reason of not making, any such inspection. Each Inspecting Party shall bear its own expenses in reasonably out-of-pocket expenses in connection with any such inspection during the continuance of an Event of Default, except during the Section 1110 Period.

(f) An Independent Appraiser’s Certificate shall be sufficient evidence of the Fair Market Value of any property under this Agreement.

Section 5.08 Independent Appraiser’s Certificate. Within fifteen (15) business days after each January 1 commencing with January 1, 2009, Airlines shall furnish the Collateral Agent with an Independent Appraiser’s Certificate stating, in the opinion of the Independent Appraiser, the Fair Market Value of the Pledged Spare Parts and the Pledged Spare Engines as of such January 1 or any date during such fifteen (15) Business Day period thereafter.

Section 5.09 International Registry. Airlines shall establish a valid and existing account with the International Registry and appoint an Administrator and/or a Professional User (each as defined in the Cape Town Treaty) reasonably acceptable to the Collateral Agent to make registrations in regards to the Pledged Spare Engines. Collateral Agent and Airlines shall register and hereby by consent to registration of a first priority Prospective International Interest or International Interest, in connection with the Pledged Spare Engines which shall be searchable in the International Registry to the satisfaction of Collateral Agent.

Section 5.10 Release of Lessor Liens. Airlines shall no later than ninety (90) days after the date hereof file with the FAA the FAA Lease Terminations and cause the release and termination of the Lessor Liens.

OBLIGATIONS ENFORCEABLE BY AIRLINES

Section 6.01 Release of Liens on Collateral.

(a) The Collateral Agent’s Liens upon the Collateral will be released:

(i) in whole, on the Discharge Date;

(ii) as to a release of less than all or substantially all of the Collateral, if (A) consent to the release of all Liens on such Collateral has been given by a Securityholder Instruction and (B) such release has become effective in accordance with the terms of such Securityholder Instruction;

(iii) in accordance with the provisions of this Agreement and the other Operative Agreements as in effect from time to time, as applicable; or

(iv) upon any sale, transfer, exchange or other disposition of Collateral if such sale, transfer, exchange or other disposition is not prohibited by the terms of this Agreement or any other Operative Agreement.

(b) The Collateral Agent agrees for the benefit of Airlines that if the Collateral Agent at any time receives:

(i) an Officers’ Certificate stating that (A) each signing officer has read this Article VI and understands the provisions and the definitions relating hereto, (B) such officer has made such examination or investigation as is necessary to enable him or her to express an informed opinion as to whether or not the conditions precedent in this Agreement and all other Operative Agreements, if any, relating to the release of the Collateral have been complied with and (C) in the opinion of such officer, such conditions precedent, if any, have been complied with; and

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

then the Collateral Agent shall execute (with such acknowledgements and/or notarizations as are required) and deliver to Airlines (or its designee) such documents and instruments, and take such other actions, in each case as Airlines may reasonably request to evidence such release on or before the later of (x) the date specified in such request for such release and (y) the fifth day after the date of receipt of the items required by this Section 6.01(b) by the Collateral Agent.

(c) The Collateral Agent hereby agrees that in the case of any release pursuant to clause (iv) of Section 6.01(a), if the terms of any such sale, transfer, exchange or other disposition require the payment of the purchase price to be contemporaneous with the delivery of the applicable release, then, at the written request of and at the expense of Airlines, the Collateral Agent will either (A) be present at and deliver the

release at the closing of such transaction or (B) deliver the release under customary escrow arrangements that permit such contemporaneous payment and delivery of the release.

Section 6.02 Collateral Agent not Required to Serve, File or Record. The Collateral Agent is not required to file, register or record any instrument releasing or subordinating its Liens on any Collateral; provided, however, that if Airlines shall make a written demand for a termination statement under Section 9-513(c) of the UCC, the Collateral Agent shall, at the expense of Airlines, comply with the written request to comply with the requirements of such UCC provision.

Section 6.03 Release of Liens in Respect of Notes. The Collateral Agent’s Lien will no longer secure the Notes outstanding under the Indenture or any other Secured Obligations, and the right of the Securityholders to the benefits and proceeds of the Collateral Agent’s Lien on the Collateral will terminate and be discharged:

(a) upon satisfaction and discharge of the Indenture as set forth under Section 8.01 of the Indenture; or

(b) upon payment in full and discharge of all Secured Obligations that are outstanding, due and payable under the Indenture at the time the Notes are paid in full and discharged.

Section 6.04 Remedies.

(a) If an Event of Default shall have occurred and be continuing and so long as the same shall continue unremedied, then and in every such case the Collateral Agent may exercise any or all of the rights and powers and pursue any and all of the remedies pursuant to this Agreement and shall have and may exercise all of the rights and remedies of a secured party under the UCC and may take possession of all or any part of the properties covered or intended to be covered by the Lien created hereby or pursuant hereto and may sell the Collateral as a whole or from time to time in part; provided, that the Collateral Agent shall give Airlines twenty days’ prior written notice of its intention to sell any Collateral. Without limiting any of the foregoing, it is understood and agreed that the Collateral Agent may exercise any right of sale, lease or other disposition of any Collateral available to it, even though it shall not have taken possession of such Collateral and shall not have possession thereof at the time of such sale, lease or other disposition.

(b) The Securityholders shall be entitled, at any sale pursuant to this Section 6.04, to credit against any purchase price bid at such sale by such holder all or any part of the unpaid obligations owing to such Securityholder and secured by the Lien of this Agreement (only to the extent that such purchase price would have been paid to such Securityholder pursuant to this Agreement hereof if such purchase price were paid in cash and the foregoing provisions of this subsection (b) were not given effect).

(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 Agreement, the unpaid amount of all Secured

Obligations 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.

Section 6.05 Return of Collateral, Etc.

(a) If an Event of Default shall have occurred and be continuing, at the request of the Collateral Agent, Airlines shall assemble the Collateral and make it available to the Collateral Agent at the Designated Locations and 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 Airlines 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 Airlines to execute and deliver such instruments and documents to the Collateral Agent, to the entry of which judgment Airlines hereby specifically consents to the fullest extent permitted by Law, and (ii) pursue all or part of such Collateral wherever it may be found and may enter any of the premises of Airlines wherever such Collateral may be or are supposed to be and search for such Collateral and take possession of and remove such Collateral. 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.

(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 exercise all rights and powers of Airlines 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 rents, revenues and other proceeds 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 rents, revenues and other proceeds 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 Collateral 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 Airlines), 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.

Section 6.06 Remedies Cumulative. To the fullest extent permitted by applicable Law, each and every right, power and remedy given to the Collateral Agent specifically or otherwise in this Agreement shall be cumulative and shall be in addition to every other right, power and remedy herein specifically given or now or hereafter existing at Law, in equity or by statute, and each and every right, power and remedy whether specifically herein given or otherwise existing may be exercised from time to time and as often and in such order as may be deemed expedient by the Collateral Agent, and the exercise or the beginning of the exercise of any power or remedy shall not be construed to be a waiver of the right to exercise at the same time or thereafter any other right, power or remedy. To the fullest extent permitted by applicable Law, no delay or omission by the Collateral Agent in the exercise of any right, remedy or power or in the pursuance of any remedy shall impair any such right, power or remedy or be construed to be a waiver of any default on the part of Airlines or to be an acquiescence therein.

Section 6.07 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 Airlines 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 Airlines or the Collateral Agent shall continue as if no such proceedings had been instituted.

Section 6.08 Waiver of Past Defaults. Upon written instruction from a Securityholder Instruction, the Collateral Agent shall waive any past default hereunder and its consequences and upon any such waiver such default shall cease to exist and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Agreement, but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon; provided, that in the absence of written instructions from all the Securityholders, the Collateral Agent shall not waive any default (i) in the payment of all or any portion of the Secured Obligations then outstanding, or (ii) in respect of a covenant or provision hereof which, under Article IX, cannot be modified or amended without a Securityholder Instruction.

Section 6.09 Appointment of Receiver. To the fullest extent permitted by applicable Law, 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 Airlines 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 6.10 Collateral Agent Authorized to Execute Bills of Sale, Etc. Airlines irrevocably appoints, to the fullest extent permitted by applicable Law, while an Event of Default has occurred and is continuing, the Collateral Agent the true and lawful attorney-in-fact of Airlines (which appointment is coupled with an interest) in its name and stead and on its behalf, for the purpose of effectuating any sale, assignment, transfer or delivery for the enforcement of the Lien of this Agreement, whether pursuant to foreclosure or power of sale, assignments and other instruments as may be necessary or appropriate or entering into any agreement described in Section 6.06, with full power of substitution, Airlines hereby ratifying and confirming all that such attorney or any substitute shall do by virtue hereof in accordance with applicable law. Nevertheless, if so requested by the Collateral Agent or any purchaser, Airlines shall ratify and confirm any such sale, assignment, transfer or delivery, by executing and delivering to the Collateral Agent or such purchaser all bills of sale, assignments, releases and other proper instruments to effect such ratification and confirmation as may be designated in any such request.

Section 6.11 Rights of Securityholders to Receive Payment. Notwithstanding any other provision of this Agreement, the right of any Securityholder to receive payment of principal of, and premium, if any, and interest on the Notes on or after the Stated Maturity, or to bring suit for the enforcement of any such payment in accordance with the terms of the Indenture, shall not be impaired or affected without a Securityholder Instruction. The proceeds of, and other realization upon, the Collateral by virtue of the exercise of remedies under this Section 6.13 shall be applied in accordance with Section 6.06.

Section 6.12 Limitations Under Civil Reserve Airfleet Program. Notwithstanding any other provision of this Agreement, during any period that a Spare Engine is subject to the Civil Reserve Air Fleet Program in accordance with the provisions of Section 5.02 and in possession of the U.S. Government, the Collateral Agent shall not, on account of any Event of Default, be entitled to exercise any of the remedies pursuant to this Article VI in such manner as to limit Airlines’ control under this Agreement of such Spare Engine, unless at least 60 days’ (or such other period as may then be applicable under the Civil Reserve Air Fleet program) written notice of such Event of Default hereunder shall have been given by the Collateral Agent by registered or certified mail to Airlines (and any Permitted Lessee) with a copy addressed to the Contracting Office Representative for the Air Mobility Command of the United States Air Force under any contract with Airlines (or any Permitted Lessee) relating to such Spare Engine.

Section 6.13 Application of Proceeds. Except as otherwise expressly provided in this Agreement and except as provided below in this Section 6.13, the Proceeds of, or other realization upon, all or any part of the Collateral by virtue of the exercise of remedies under Section 6.04, and any other cash at the time held by Collateral Agent or under this Agreement, shall be applied by Collateral Agent:

First, to the payment of the reasonable costs and expenses of such exercise of remedies, including reasonable out-of-pocket costs and expenses of Collateral Agent, the reasonable fees and expenses of its agents and counsel and all other reasonable expenses incurred and advances made by Collateral Agent in that connection;

Next, to the payment in full of the remaining Secured Obligations equally and ratably in accordance with their respective amounts then due and owing or as Collateral Agent holding the same may otherwise agree, as provided for in Article 2 of the Supplemental Indenture; and

Finally, subject to the rights of any other holder of any Lien or encumbrance in the relevant Collateral, to the payment to Airlines, or its respective successors or assigns, or as a court of competent jurisdiction may direct, of any surplus then remaining.

(a) The Collateral Agent may at any time solicit written confirmatory instructions, in the form of a Securityholder Instruction, an Officers’ Certificate or an order of a court of competent jurisdiction, as to any action that it may be requested or required to take, or that it may propose to take, in the performance of any of its obligations under this Agreement or the other Operative Agreements, the Collateral Agent shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to the terms of this Agreement.

(b) No written direction given to the Collateral Agent by a Securityholder Instruction that in the sole judgment of the Collateral Agent imposes, purports to impose or might reasonably be expected to impose upon the Collateral Agent any obligation or liability not set forth in or arising under this Agreement and the other Operative Agreements will be binding upon the Collateral Agent unless the Collateral Agent elects, at its sole option, to accept such direction.

Section 7.05 Limitation of Liability. The Collateral Agent will not be responsible or liable for any action taken or omitted to be taken by it hereunder or under any other Operative Agreements, except for its own gross negligence, bad faith or willful misconduct as determined by a court of competent jurisdiction in a final nonappealable judgment.

Section 7.06 Documents in Satisfactory Form. The Collateral Agent will be entitled to require that all agreements, certificates, opinions, instruments and other documents at any time submitted to it, including those expressly provided for in this Agreement, be delivered to it in a form and with substantive provisions reasonably satisfactory to it.

Section 7.07 Entitled to Rely. The Collateral Agent may seek and rely upon, and shall be fully protected in relying upon, any judicial order or judgment, upon any advice, opinion or statement of legal counsel (who may be counsel to Airlines or the Company), independent consultants and other experts selected by it in good faith and upon any certification, instruction, notice or other writing delivered to it by Airlines in compliance with the provisions of this Agreement, without being required to determine the authenticity thereof or the correctness of any fact stated therein or the propriety or validity of service thereof. The Collateral Agent may act in reliance upon any instrument comporting with the provisions of this Agreement or any signature reasonably believed by it to be genuine and may assume that any Person purporting to give notice or receipt or advice or make any statement or execute any document in connection with the provisions hereof or the other Operative Agreements has been duly authorized to do so. To the extent an Officers’ Certificate or opinion of counsel is required or permitted under this Agreement to be delivered to the Collateral Agent in respect of any matter, the Collateral Agent may rely conclusively on an Officers’ Certificate or opinion of counsel as to such matter and such Officers’ Certificate or opinion of counsel shall be full warranty and protection to the Collateral Agent for any action taken, suffered or omitted by it under the provisions of this Agreement and the other Operative Agreements.

Section 7.08 Secured Debt Default. The Collateral Agent will not be required to inquire as to the occurrence or absence of any default and will not be affected by or required to act upon any notice or knowledge as to the occurrence of any default unless and until it is directed by a Securityholder Instruction.

Section 7.09 Actions by Collateral Agent. As to any matter not expressly provided for by this Agreement or the other Operative Agreements, the Collateral Agent will act or refrain from acting as directed by a Securityholder Instruction and will be fully protected if it does so, and any action taken, suffered or omitted pursuant to hereto or thereto shall be binding on the holders of Secured Obligations.

Section 7.10 Security or Indemnity in favor of the Collateral Agent. The Collateral Agent will not be required to advance or expend any funds or otherwise incur any financial liability in the performance of its duties or the exercise of its powers or rights hereunder unless it has been provided with security or indemnity reasonably satisfactory to it against any and all liability or expense which may be incurred by it by reason of taking or continuing to take such action.

Section 7.11 Rights of the Collateral Agent. In the event of any conflict between any terms and provisions set forth in this Agreement and those set forth in any other Operative Agreements, the terms and provisions of this Agreement shall supersede and control the terms and provisions of such other Operative Agreements. In the event there is any bona fide, good faith disagreement between the other parties to this Agreement or any of the other Operative Agreements resulting in adverse claims being made in connection with Collateral held by the Collateral Agent and the terms of this Agreement or any of the other Operative Agreements do not unambiguously mandate the action the Collateral Agent is to take or not to take in connection therewith under the circumstances then existing, or the Collateral Agent is in doubt as to what action it is required to take or not to take hereunder or under the other Operative Agreements, it will be entitled to refrain from taking any action (and will incur no liability for doing so) until directed otherwise in writing by a request signed jointly by the parties hereto entitled to give such direction or by order of a court of competent jurisdiction.

Section 7.12 Limitations on Duty of Collateral Agent in Respect of Collateral.

(a) Beyond the exercise of reasonable care in the custody of Collateral in its possession, the Collateral Agent will have no duty as to any Collateral in its possession or control or in the possession or control of any agent or bailee or any income thereon or as to preservation of rights against prior parties or any other rights pertaining thereto and the Collateral Agent will not be responsible for filing any financing or continuation statements or recording any documents or instruments in any public office at any time or times or otherwise perfecting or maintaining the perfection of any Liens on the Collateral. The Collateral Agent will be deemed to have exercised reasonable care in the custody of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which it accords its own property, and the Collateral Agent will not be liable or responsible for any loss or diminution in the value of any of the Collateral by reason of the act or omission of any carrier, forwarding agency or other agent or bailee selected by the Collateral Agent in good faith.

(b) The Collateral Agent will not be responsible for the existence, genuineness or value of any of the Collateral, for the validity, perfection, priority or enforceability of the Liens in any of the Collateral, whether impaired by operation of law or by reason of any action or omission to act on its part hereunder, except to the extent such action or omission constitutes gross negligence, bad faith or willful misconduct on the part of the Collateral Agent, for the validity or sufficiency of the Collateral or any agreement or assignment contained therein, for the validity of the title of Airlines to the Collateral, for insuring the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance of the Collateral. The Collateral Agent hereby disclaims any representation or warranty to the present and future holders of the Secured Obligations concerning the perfection of the Liens granted hereunder or in the value of any of the Collateral.

Section 7.13 Assumption of Rights, Not Assumption of Duties. Notwithstanding anything to the contrary contained herein:

(a) each of the parties hereto will remain liable under each of the Operative Agreements (other than this Agreement) to the extent set forth therein to perform all of their respective duties and obligations thereunder to the same extent as if this Agreement had not been executed;

(b) the exercise by the Collateral Agent of any of its rights, remedies or powers hereunder will not release such parties from any of their respective duties or obligations under the other Operative Agreements; and

(c) the Collateral Agent will not be obligated to perform any of the obligations or duties of any of the parties thereunder other than the Collateral Agent.

Section 7.14 Additional Provisions Relating to the Collateral Agent.

(a) The Collateral Agent may refuse to follow any direction that conflicts with law or this Agreement, the Indenture or (subject to Section 7.11) any document or that would involve the Collateral Agent in personal liability; provided that the Collateral Agent may take any other action deemed proper by the Collateral Agent that is not inconsistent with such direction. Prior to taking any action under this Agreement or any of the Operative Agreements, the Collateral Agent shall be entitled to indemnification reasonably satisfactory to it against all losses and expenses caused by taking or not taking such action.

(b) The Collateral Agent shall be accountable only for amounts that it actually receives as a result of the exercise of its powers hereunder and under any Other Operative Agreement, and neither it nor any of its officers, directors, employees or agents shall have any duty or liability or be responsible to Airlines for any act or failure to act hereunder, except for its own gross negligence, bad faith or willful misconduct. Nothing contained in this Agreement shall be construed as requiring or obligating the Collateral Agent, and the Collateral Agent shall not, absent an act by a Securityholder Instruction, be required or obligated, to (i) present or file any claim or notice or take any action with respect to any Collateral or in connection therewith or (ii) notify Airlines of any decline in the value of any Collateral.

(c) Neither the Collateral Agent nor any of its directors, officers, employees or agents shall be liable for failure to demand, collect or realize upon all or any part of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of Airlines.

(d) No provision of this Agreement or any Operative Agreement shall be deemed to impose any duty or obligation on the Collateral Agent to perform any act or acts, receive or obtain any interest in property or exercise any interest in property, or exercise any right, power, duty or obligation conferred or imposed on it in any jurisdiction in which it shall be illegal, or in which the Collateral Agent shall be unqualified or incompetent in accordance with applicable law, to perform any such act or

acts, to receive or obtain any such interest in property or to exercise any such right, power, duty or obligation; and no permissive or discretionary power or authority available to the Collateral Agent shall be construed to be a duty.

(e) In no event shall the Collateral Agent be liable for any failure or delay in the performance of its obligations hereunder or under any of the other Operative Agreements because of circumstances beyond the Collateral Agent’s control, including, acts of God, flood, war (whether declared or undeclared), terrorism, fire, riot, strikes or work stoppages for any reason, embargo, government action, including any laws, ordinances, regulations or the like which restrict or prohibit the providing of the services contemplated by this Agreement, or the failure of equipment or interruption of communications or computer facilities, and other, causes beyond the Collateral Agent’s control whether or not of the same class or kind as specifically named above.

(f) The Collateral Agent shall not be liable for any action taken, suffered, or omitted to be taken by it in good faith and reasonably believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Agreement or any of the other Operative Agreements.

(g) Notwithstanding anything to the contrary contained in this Agreement or any of the other Operative Agreements, under no circumstances shall the Collateral Agent be liable for any special, punitive, exemplary or consequential damages.

(h) The Collateral Agent shall have no liability to Airlines for interest on any money received by it under this Agreement or any of the other Operative Agreements except as otherwise agreed in writing with Airlines.

Section 7.15 Appointment of Co-Collateral Agent. Solely for the purpose of meeting any legal requirement of any jurisdiction in which any part of the Collateral may at the time be located, the Collateral Agent shall have the power and may execute and deliver all instruments necessary to appoint one or more Persons to act as a co-Collateral Agent or separate Collateral Agent or separate Collateral Agents, of all or any part of the Collateral, and to vest in such Person or Persons, in such capacity and for the benefit of the Securityholders, such title to the Collateral, or any part hereof, and subject to the other provisions of this Section, such powers, duties, obligations, and rights as the Collateral Agent may consider necessary or desirable. No co-Collateral Agent or separate Collateral Agent hereunder shall be required to meet the terms of eligibility as a successor Collateral Agent under Section 8.02 and no notice to the Securityholders of the appointment of any co-Collateral Agent or separate Collateral Agent shall be required under this Agreement or any of the other Operative Agreements.

(a) Every separate Collateral Agent and co-Collateral Agent shall, to the extent permitted by law, be appointed and act subject to the following provisions and conditions:

(i) all rights, powers, duties and obligations conferred or imposed upon the Collateral Agent shall be conferred or imposed upon and exercised or performed by the Collateral Agent and such separate Collateral

Agent or co-Collateral Agent jointly (it being understood that such separate Collateral Agent or co-Collateral Agent is not authorized to act separately without the Collateral Agent joining in such act), except to the extent that under any law of any jurisdiction in which any particular act or acts are to be performed the Collateral Agent shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations (including the holding of title to the Collateral or any portion thereof in any such jurisdiction) shall be exercised and performed singly by such separate Collateral Agent or co-Collateral Agent, but solely at the direction of the Collateral Agent;

(ii) no Collateral Agent shall be personally liable by reason of any act or omission of any other Collateral Agent under the Operative Agreements; and

(iii) the Collateral Agent may at any time accept the resignation of or remove any separate Collateral Agent or co-Collateral Agent.

(b) Any notice, request or other writing given to the Collateral Agent shall be deemed to have been given to each of the then separate Collateral Agents and co-Collateral Agents, as effectively as if given to each of them. Every instrument appointing any separate Collateral Agent or co-Collateral Agent shall refer to this Agreement and the conditions of this Section 7.15. Each separate Collateral Agent and co-Collateral Agent, upon its acceptance of the obligations conferred, shall be vested with the estates or property specified in its instrument of appointment, either jointly with the Collateral Agent or separately, as may be provided therein, subject to all the provisions of this Agreement, specifically including every provision of this Agreement relating to the conduct of, affecting the liability of, or affording protection or rights (including the rights to compensation, reimbursement and indemnification hereunder) to, the Collateral Agent. Every such instrument shall be filed with the Collateral Agent.

(c) Any separate Collateral Agent or co-Collateral Agent may at any time constitute the Collateral Agent its agent or attorney-in-fact with full power and authority, to the extent not prohibited by law, to do any lawful act under or in respect of this Agreement on its behalf and in its name. If any separate Collateral Agent or co-Collateral Agent shall die, become incapable of acting, resign or be removed, all of its estates, properties, rights, remedies and obligations shall vest in and be exercised by the Collateral Agent, to the extent permitted by law, without the appointment of a new or successor Collateral Agent.

ARTICLE VIII

RESIGNATION AND REMOVAL OF THE COLLATERAL AGENT

Section 8.01 Resignation or Removal of Collateral Agent. Subject to the appointment of a successor Collateral Agent as provided in Section 8.02 and the acceptance of such appointment by the successor Collateral Agent:

(a) the Collateral Agent may resign at any time by giving not less than 30 days’ notice of resignation to Airlines; and

(b) the Collateral Agent may be removed at any time, with or without cause, by a Securityholder Instruction.

Section 8.02 Appointment of Successor Collateral Agent. Upon any such resignation or removal, a successor Collateral Agent may be appointed by a Securityholder Instruction. If no successor Collateral Agent has been so appointed and accepted such appointment within 30 days after the predecessor Collateral Agent gave notice of resignation or was removed, the retiring Collateral Agent may (at the expense of Airlines), at its option, appoint a successor Collateral Agent, or petition a court of competent jurisdiction for appointment of a successor Collateral Agent, which must be a bank or trust company:

(a) authorized to exercise corporate trust powers; and

(b) having a combined capital and surplus of at least $500,000,000.

The Collateral Agent will fulfill its obligations hereunder until a successor Collateral Agent meeting the requirements of this Section 8.02 has accepted its appointment as Collateral Agent and the provisions of Section 8.03 have been satisfied.

Section 8.03 Succession. When the Person so appointed as successor Collateral Agent accepts such appointment:

(a) such Person will succeed to and become vested with all the rights, powers, privileges and duties of the predecessor Collateral Agent, and the predecessor Collateral Agent will be discharged from its duties and obligations hereunder; and

(b) the predecessor Collateral Agent will (at the expense of Airlines) promptly transfer all Liens and collateral security and other property of the Trust Estate within its possession or control to the possession or control of the successor Collateral Agent and will execute instruments and assignments as may be necessary or desirable or reasonably requested by the successor Collateral Agent to transfer to the successor Collateral Agent all Liens, interests, rights, powers and remedies of the predecessor Collateral Agent in respect of the Operative Agreements.

Thereafter the predecessor Collateral Agent will remain entitled to enforce the immunities granted to it in Article VII.

Section 8.04 Merger, Conversion or Consolidation of Collateral Agent. Any Person into which the Collateral Agent may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which the Collateral Agent shall be a party, or any Person succeeding to all or substantially all of the corporate trust business of the Collateral Agent shall be the successor of the Collateral Agent pursuant to Section 8.03, provided that without the execution or filing of any paper with any party hereto or any further act on the part of any of the parties hereto, except where an instrument of transfer or assignment is required by law to effect such succession, anything herein to the contrary notwithstanding, such Person satisfies the eligibility requirements specified in clauses (a) through (d) of Section 8.02.

ARTICLE IX

MISCELLANEOUS PROVISIONS

Section 9.01 Amendment.

(a) No amendment or supplement to the provisions of any Operative Agreements will be effective without the approval of the Collateral Agent acting as directed by a Securityholder Instruction, except that:

(ii) no amendment or supplement that imposes any obligation upon the Collateral Agent or adversely affects the rights of the Collateral Agent will become effective without the additional consent of the Collateral Agent.

(b) The Collateral Agent will not enter into any amendment or supplement unless it has received an Officers’ Certificate to the effect that such amendment or supplement will not result in a breach of any provision or covenant contained in any of the Operative Agreements. Prior to executing any amendment or supplement pursuant to this Section 9.01, the Collateral Agent will be entitled to receive an opinion of counsel of Airlines to the effect that the execution of such document is authorized or permitted hereunder, and with respect to amendments adding Collateral, an opinion of counsel of Airlines addressing customary perfection.

Section 9.02 Voting. In connection with any matter under this Agreement requiring a vote of Securityholders, each Securityholder will cast its vote in accordance with the Indenture.

(a) Except as provided in Section 7.02 and Section 7.15 the Collateral Agent may not, in its capacity as such, delegate any of its duties or assign any of its rights hereunder, and any attempted delegation or assignment of any such duties or rights shall be null and void.

(b) All obligations of the Collateral Agent hereunder will inure to the sole and exclusive benefit of, and be enforceable by, Securityholders, who will be entitled to enforce this Agreement as a third-party beneficiary hereof, and all of their respective successors and assigns.

(c) Airlines may not delegate any of its duties, except in accordance with the Indenture or assign any of its rights hereunder, and any attempted delegation or assignment of any such duties or rights will be null and void. All obligations of the Airlines hereunder will inure to the sole and exclusive benefit of, and be enforceable by, the Collateral Agent, on behalf of itself and on behalf of each Securityholder, whom will be entitled to enforce this Agreement as a third-party beneficiary hereof, and all of their respective successors and assigns.

Section 9.04 Delay and Waiver. No failure to exercise, no course of dealing with respect to the exercise of, and no delay in exercising, any right, power or remedy arising under this Agreement or any of the other Operative Agreements will impair any such right, power or remedy or operate as a waiver thereof. No single or partial exercise of any such right, power or remedy will preclude any other or future exercise thereof or the exercise of any other right, power or remedy. The remedies herein are cumulative and are not exclusive of any remedies provided by law.

(b) All amounts due under this Section 9.08 will be payable upon demand.

(c) To the extent that the undertakings to defend, indemnify, pay and hold harmless set forth in Section 9.08(a) may be unenforceable in whole or in part because they violate any law or public policy, to the fullest extent permitted by applicable Law, Airlines will contribute the maximum portion that it is permitted to pay and satisfy under applicable law to the payment and satisfaction of all Indemnified Liabilities incurred by Indemnitees or any of them.

(d) To the fullest extent permitted by applicable Law, Airlines will not assert any claim against any Indemnitee, on any theory of liability, for any lost profits or special, indirect or consequential damages or (to the fullest extent a claim for punitive damages may lawfully be waived) any punitive damages arising out of, in connection with, or as a result of, this Agreement or any other Operative Agreement or any agreement or instrument or transaction contemplated hereby or relating in any respect to any Indemnified Liability, and to the fullest extent permitted by applicable Law, Airlines hereby forever waives, releases and agrees not to ▇▇▇ upon any claim for any such lost profits or special, indirect, consequential or (to the fullest extent lawful) punitive damages, whether or not accrued and whether or not known or suspected to exist in its favor.

By executing and delivering this Agreement, Airlines, for itself and in connection with its properties, irrevocably, to the fullest extent permitted by applicable Law:

(a) accepts generally and unconditionally the nonexclusive jurisdiction and venue of such courts;

(b) waives any defense of forum non conveniens;

(c) agrees that service of all process in any such proceeding in any such court may be made by registered or certified mail, return receipt requested, to such party at its address provided in accordance with Section 9.05;

(e) agrees each party hereto retains the right to serve process in any other manner permitted by law or to bring proceedings against any party in the courts of any other jurisdiction.

Section 9.14 Waiver of Jury Trial. To the fullest extent permitted by applicable Law, each party to this Agreement waives its rights to a jury trial of any claim or cause of action based upon or arising under this Agreement or any of the other Operative Agreements or any dealings between them relating to the subject matter of this Agreement or the intents and purposes of the other Operative Agreements. The scope of this waiver is intended to be all-encompassing of any and all disputes that may be filed in any court and that relate to the subject matter of this Agreement and the other Operative Agreements, including contract claims, tort claims, breach of duty claims and all other common law and statutory claims. Each party to this Agreement acknowledges that this waiver is a material inducement to enter into a business relationship, that each party hereto has already relied on this waiver in entering into this Agreement, and that each party hereto will continue to rely on this waiver in its related future dealings. Each party hereto further warrants and represents that it has reviewed this waiver with its legal counsel and that it knowingly and voluntarily waives its jury trial rights following consultation with legal counsel. This waiver is irrevocable, meaning that it may not be modified either orally or in writing (other than by a mutual written waiver specifically referring to this Section 9.14 and executed by each of the parties hereto), and this waiver will apply to any subsequent amendments, renewals, supplements or modifications of or to this Agreement or any of the other Operative Agreements or to any other documents or agreements relating thereto. In the event of litigation, this Agreement may be filed as a written consent to a trial by the court.

Section 9.15 Counterparts. This Agreement may be executed in any number of counterparts (including by facsimile), each of which when so executed and delivered will be deemed an original, but all such counterparts together will constitute but one and the same instrument.

Section 9.16 Effectiveness. This Agreement will become effective upon the execution of a counterpart hereof by each of the parties hereto and receipt by each party of written notification of such execution and written or telephonic authorization of delivery thereof; provided, that if the Supplemental Indenture is rendered null and void and of no effect by operation of Section 3.1 thereof, then this Agreement shall also be null and void and of no effect.

Section 9.17 Insolvency. To the fullest extent permitted by applicable Law, this Agreement will be applicable both before and after the commencement of any Insolvency or Liquidation Proceeding by or against Airlines. To the fullest extent permitted by applicable Law, the relative rights, as provided for in this Agreement, will continue after the commencement of any such Insolvency or Liquidation Proceeding on the same basis as prior to the date of the commencement of any such case, as provided in this Agreement.

(i) Airlines will carry or cause to be carried at all times, at no expense to any Additional Insured (as defined below), third party liability insurance with respect to the Pledged Spare Parts which is (i) of an amount and scope as may be customarily maintained by Airlines for equipment similar to the Pledged Spare Parts or such Aircraft on which a Pledged Spare Engine is installed, as applicable, and (ii) maintained in effect with insurers of nationally or internationally recognized responsibility (such insurers being referred to herein as “Approved Insurers”).

(ii) During any period that a Pledged Spare Engine is on the ground and not in operation, Airlines may carry or cause to be carried as to such Pledged Spare Engine, in lieu of the insurance required by Section A(i) above, except that (i) the amount of coverage shall not be required to exceed the amounts of public liability and property damage insurance from time to time applicable to engines owned or leased and operated by Airlines of the same type as such Pledged Spare Engine which is on the ground and not in operation and (ii) the scope of the risks covered and the type of insurance shall be the same as from time to time shall be applicable to engines owned or leased and operated by Airlines of the same type as such Pledged Spare Engine which is on the ground and not in operation.

B.	Property Insurance

Airlines will carry or cause to be carried at all times, at no expense to any Additional Insured, with Approved Insurers insurance covering physical damage to the Pledged Spare Parts providing for the reimbursement of the actual expenditure incurred in repairing or replacing any damaged or destroyed Pledged Spare Part or, if not repaired or replaced, for the payment of the amount it would cost to repair or replace such Pledged Spare Part, on the date of loss, with proper deduction for obsolescence and physical depreciation.

Any policies of insurance carried in accordance with this Section B covering the Pledged Spare Parts and any policies taken out in substitution or replacement for any such policies shall provide that (i) all insurance proceeds paid under such policies as a result of the occurrence of an Event of Loss with respect to any Pledged Spare Parts involving proceeds in excess of the Threshold Amount will be paid to the Collateral Agent, it being agreed that the Collateral Agent shall pay the amount of such proceeds to Airlines or its order to the extent required under Section 5.04(b) of the Agreement, and (ii) the entire amount of any insurance proceeds not involving an Event of Loss with respect to any Pledged Spare Parts or involving proceeds of the Threshold Amount or less shall be paid to Airlines or its order; provided that if an Event of Default shall have occurred and be continuing and the insurers have been notified thereof by the Collateral Agent, the amount of any proceeds of any loss with respect to the Pledged Spare Parts shall be paid to the Collateral Agent.

▇.	▇▇▇▇ Insurance

(i) Except as provided in Section C(ii) below, Airlines will carry or cause to be carried at all times, at no expense to any Additional Insured, with Approved Insurers “all-risk” ground and flight aircraft hull insurance covering each Aircraft on which a Pledged Spare Engine is installed and all-risk property damage insurance covering each Pledged Spare Engine while removed from an Aircraft which are of the type as from time to time applicable to engines owned or leased and operated by Airlines of the same type as such Pledged Spare Engine for an amount in the aggregate applicable to all of the Pledged Spare Engines at all times not less than 110% of the aggregate Pro Rata Share Amount for all Pledged Spare Engines.

Any policies of insurance carried in accordance with this Section C(i) covering the Pledged Spare Engines and any policies taken out in substitution or replacement for any such policies shall provide that (1) all insurance proceeds paid under such policies as a result of the occurrence of an Event of Loss with respect to any Pledged Spare Engines involving proceeds in excess of the Threshold Amount will be paid to the Collateral Agent (it being agreed that the Collateral Agent shall pay the amount of such proceeds to Airlines or its order to the extent required under the Agreement), except in the case of a loss with respect to a Pledged Spare Engine while installed on an aircraft, in which case Airlines (or the applicable Permitted Lessee) shall endeavor to arrange for any payment of insurance proceeds in respect of such loss to be held for the account of the Collateral Agent whether such payment is made to Airlines (or the applicable Permitted Lessee) or any third party (provided that the foregoing shall not affect Airlines’ obligation, in the case of an Event of Loss with respect to a Pledged Spare Engine, either to replace such Pledged Spare Engine or to provide Cash Collateral to the Collateral Agent pursuant to the Agreement), it being understood and agreed that in the case of any payment to the Collateral Agent otherwise than in respect of an Event of Loss, the Collateral Agent shall, upon receipt of an officers’ certificate stating that the damage giving rise to such payment shall have been repaired or that such payment shall then be required to pay for repairs then being made, pay the amount of such payment to Airlines or its order, unless an Event of Default shall have occurred and be continuing and the insurers have been notified thereof by the Collateral Agent and (2) the entire amount of any insurance proceeds not involving an Event of Loss with respect to any Pledged Spare Engines or involving proceeds of the Threshold Amount or less shall be paid to Airlines or its order; provided that if a Special Default or Event of Default shall have occurred and be continuing and the insurers have been notified thereof by the Collateral Agent, the amount of any proceeds of any loss with respect to the Pledged Spare Engines shall be paid to the Collateral Agent.

(ii) During any period that an Aircraft or a Spare Engine is on the ground and not in operation, the Owner may carry or cause to be carried as to such Aircraft or Spare Engine, in lieu of the insurance required by Section A(i) above, insurance otherwise conforming with the provisions of said Section A(i) except that the scope of the risks and the type of insurance shall be the same as from time to time applicable, in the case of an Aircraft, to aircraft owned or leased and operated by the Owner of the same type or, in the case of a Spare Engine, to engines owned or leased and operated by Airlines, in any such case similarly on the ground and not in operation, provided that Airlines shall maintain insurance against risk of loss or damage for an amount in the aggregate applicable to all of the Pledged Spare Engines not less than 110% of the aggregate Pro Rata Share Amount for all Pledged Spare Engines.

D.	War-Risk, Hijacking and Allied Perils Insurance

If Airlines (or any Permitted Lessee) shall at any time operate or propose to operate an Aircraft while a Pledged Spare Engine is installed thereon (i) in any area of recognized hostilities or (ii) on international routes and war-risk, hijacking or allied perils insurance is maintained by the Owner (or, if such Pledged Spare Engine is subject to a Permitted Lease, such Permitted Lessee) with respect to other aircraft owned or leased and operated by Airlines (or, if such Pledged Spare Engine is subject to a Permitted Lease, such Permitted Lessee) on such routes or in such areas, Airlines (or such Permitted Lessee) shall maintain or cause to be maintained war-risk, hijacking and related perils insurance of substantially the same type carried by major United States commercial air carriers operating the same or comparable models of engines on similar routes or in such areas and in no event in an amount less than, in the case of any Pledged Spare Engine installed on such Aircraft, 110% of the Pro Rata Share Amount for such Pledged Spare Engine.

E.	General Provisions

Any policies of insurance carried in accordance with Sections A and B, including any policies taken out in substitution or replacement for such policies:

(i) shall name the Collateral Agent and the Trustee as an additional insured (collectively, the “Additional Insureds”), as their respective interests may appear;

(ii) in the case of Section A, shall provide that, in respect of the interests of the Additional Insureds in such policies, the insurance shall not be invalidated or impaired by any act or omission (including misrepresentation and nondisclosure) by Airlines (or any Permitted Lessee) or any other Person (including, without limitation, use of the Pledged Spare Parts or the Pledged Spare Engines for illegal purposes) and shall insure the Additional Insureds regardless of any breach or violation of any representation, warranty, declaration, term or condition contained in such policies by Airlines (or any Permitted Lessee);

(iii) shall provide that, if the insurers cancel such insurance for any reason whatsoever, or if the same is allowed to lapse for nonpayment of premium, or if any material change is made in the insurance which adversely affects the interest of any of the Additional Insureds, such cancellation, lapse or change shall not be effective as to the Additional Insureds for 30 days (or, in the case of nonpayment of premiums or cancellation by Airlines, 10 days or, in the case of war risk, hijacking and allied perils insurance, seven days) after receipt by the Additional Insureds of written notice by such insurers of such cancellation, lapse or change, provided 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 waive any right of recourse, subrogation, setoff, recoupment, counterclaim or other deduction against any Additional Insured;

(v) shall be primary without right of contribution from any other insurance that may be available to any Additional Insured;

(vi) in the case of Section A, shall provide that all of the liability insurance provisions thereof, except the limits of liability, shall operate in all respects as if a separate policy had been issued covering each party insured thereunder; and

(vii) shall provide that none of the Additional Insureds shall be liable for any insurance premium.

F.	Reports and Certificates; Other Information

On or prior to the date of this Agreement and on or prior to each renewal date of the insurance policies required hereunder, Airlines will furnish or cause to be furnished to the Collateral Agent insurance certificates describing in reasonable detail the insurance maintained by Airlines or any Permitted Lessee hereunder and a report, signed by Airlines’ regularly retained independent insurance broker (the “Insurance Broker”), stating the opinion of such Insurance Broker that all premiums in connection with the insurance then due have been paid and that the insurance terms are in compliance with the requirements of this Annex 2. Airlines will request the Insurance Broker to agree to advise the Collateral Agent in writing of any default in the payment of any premium of which it has knowledge and which might invalidate or render unenforceable, in whole or in part, any insurance on the Pledged Spare Parts or the Pledged Spare Engines or cause the cancellation, termination or interruption of such insurance (and, if the Insurance Broker does not so agreed, Airlines shall advise the Collateral Agent in writing of any such default in payment) and to advise the Collateral Agent in writing at least 30 days prior to the cancellation, lapse or material adverse change of any insurance maintained pursuant to this Annex 2 (or, in the case of nonpayment of premiums or cancellation by Airlines, 10 days or, in the case of war risk, hijacking and allied perils insurance, seven days or such shorter period as may be available in the international insurance market, as the case may be).

G.	Right to Pay Premiums

None of the Collateral Agent and the other Additional Insureds shall have any obligation to pay any premium, commission, assessment or call due on any such insurance (including reinsurance). Notwithstanding the foregoing, in the event of cancellation of any insurance due to the nonpayment of premiums, the Collateral Agent shall have the option, in its sole discretion, to pay any such premium in respect of the Pledged Spare Parts or the Pledged Spare Engines that is due in respect of the coverage pursuant to the Agreement and to maintain such coverage, as the Collateral Agent may require, until the scheduled expiry date of such insurance and, in such event, Airlines shall, upon demand, reimburse the Collateral Agent for amounts so paid by it.

H.	Deductibles; Self-insurance

Airlines may self-insure by way of deductible, premium adjustment or franchise provisions or otherwise in the insurance covering the risks required to be insured against pursuant to this Annex 2 in such amounts as shall be consistent with normal industry practice.
