(ii) deliver or permit any Permitted Lessee to deliver possession of any Aircraft, any Airframe, any Engine, any Spare Engine or any Part (x) to the manufacturer thereof or to any third-party maintenance provider for testing, service, repair, maintenance or overhaul work on any Aircraft, any Airframe, any Engine, any Spare Engine or any Part, or, to the extent required or permitted by the terms hereof, for alterations or modifications in or additions to any Aircraft, any Airframe, any Engine or any Spare Engine or (y) to any Person for the purpose of transport to a Person referred to in the preceding clause (x);

(ix) so long as no Event of Default shall have occurred and be continuing and subject to the provisions of the immediately following paragraph, enter into a lease with respect to any Aircraft, any Airframe, any Engine or any Spare Engine with any Permitted Air Carrier that is not then subject to any bankruptcy, insolvency, liquidation, reorganization, dissolution or similar proceeding and shall not have substantially all of its property in the possession of any liquidator, trustee, receiver or similar person (a “Permitted Lessee”); provided that, in the case only of a lease to a Permitted Foreign Air Carrier, (A) on the date of such lease the United States maintains diplomatic relations with the country of domicile of such Permitted Foreign Air Carrier (or, in the case of Taiwan, diplomatic relations at least as good as those in effect on the Closing Date) and (B) Company shall have furnished the Collateral Agent a favorable opinion of counsel, reasonably satisfactory to the Collateral Agent, in the country of domicile of such Permitted Foreign Air Carrier, that (v) the terms of such lease are the legal, valid and binding obligations of the parties thereto enforceable under the laws of such jurisdiction (subject to customary exceptions), (w) it is not necessary for the Collateral Agent to register or qualify to do business in such jurisdiction, if not already so registered or qualified, as a result, in whole or in part, of the proposed lease, (x) the Collateral Agent’s Lien in respect of the Aircraft, Airframes, Engines or Spare Engines, as the case may be, will be recognized as a first priority (subject to Permitted Liens) security interest and enforceable in such jurisdiction (including the Collateral Agent’s right to repossess such Aircraft), (y) the Laws of such jurisdiction of domicile require fair compensation by the government of such jurisdiction, payable in a currency freely convertible into Dollars, for the loss of title to the Aircraft, Airframes, Engines or Spare Engines, as the case may be, in the event of the requisition by such government of such title (unless Company shall provide insurance in the amounts required with respect to hull

[C Mortgage and Security Agreement]

insurance under this C Mortgage covering the requisition of title to the Aircraft, Airframes, Engines or Spare Engines by the government of such jurisdiction so long as the Aircraft, Airframes, Engines or Spare Engines are subject to such lease) and (z) the agreement of such Permitted Air Carrier that its rights under the lease are subject and subordinate to all the terms of this C Mortgage is enforceable against such Permitted Air Carrier under applicable law (subject to customary exceptions);

provided that (1) the rights of any Permitted Lessee or other transferee who receives possession by reason of a transfer permitted by this Section 3.02(b) (other than by a transfer of an Engine or Spare Engine which is deemed an Event of Loss) shall be subject and subordinate to, and any lease permitted by this paragraph (b) shall be expressly subject and subordinate to, all the terms of this C Mortgage, (2) the Company shall remain primarily liable for the performance of all of the terms of this C Mortgage and all the terms and conditions of this C Mortgage and the other Transaction Documents shall remain in effect, (3) the Company shall furnish to the Collateral Agent evidence reasonably satisfactory to the Collateral Agent that the insurance required pursuant to Section 3.06 remains in effect and such Permitted Lease shall require such insurance to remain in effect throughout the term thereof; (4) all necessary documents shall have been duly filed, registered or recorded in such public offices as may be required fully to preserve the first priority security interest (subject to Permitted Liens) and International Interest of the Collateral Agent in the Aircraft, Airframes, Engines or Spare Engines, as the case may be; (5) the Company shall reimburse the Collateral Agent for all of its reasonable out-of-pocket fees and expenses, including, without limitation, reasonable fees and disbursements of counsel, incurred by the Collateral Agent in connection with any such lease; and (6) the Company shall ensure that no lease or transfer of possession otherwise in compliance with this Section 3.02(b) shall permit any action not permitted to the Company hereunder. Except as otherwise provided herein and without in any way relieving the Company from its primary obligation for the performance of its obligations under this C Mortgage, the Company may in its sole discretion permit a Permitted Lessee (but not a sublessee) to exercise any or all rights which the Company would be entitled to exercise under Sections 3.02 and 3.04, and may cause a Permitted Lessee (but not a sublessee) to perform any or all of the Company’s obligations under Article III hereof, and the Collateral Agent agrees to accept actual and full performance thereof by a Permitted Lessee (but not a sublessee) in lieu of performance by the Company. The Company shall promptly, but not later than 10 Business Days after entering into such Permitted Lease, notify the Collateral Agent of the existence of such Permitted Lease with a term in excess of one year and provide a copy of such lease to the Collateral Agent.

No pooling agreement, Permitted Lease or other relinquishment of possession of any Airframe, any Engine or any Spare Engine shall in any way discharge or diminish any of the Company’s obligations to the Collateral Agent under this C Mortgage or constitute a waiver or forbearance of Collateral Agent’s rights or remedies hereunder.

The Collateral Agent agrees, and each Holder by acceptance of a Security agrees, for the benefit of the Company (and any Permitted Lessee) and for the benefit of any mortgagee or other holder of a security interest in any engine (other than an Engine or Spare Engine) owned by the Company (or any Permitted Lessee), any lessor of any engine (other than an Engine or Spare

[C Mortgage and Security Agreement]

Engine) leased to the Company (or any Permitted Lessee) and any conditional vendor of any engine (other than an Engine or Spare Engine) purchased by the Company (or any Permitted Lessee) subject to a conditional sale agreement or any other security agreement, that no interest shall be created under this C Mortgage in any engine so owned, leased or purchased and that none of the Collateral Agent, the Holders or their successors or assigns will acquire or claim, as against the Company (or any Permitted Lessee) or any such mortgagee, lessor or conditional vendor or other holder of a security interest or any successor or assignee of any thereof, any right, title or interest in such engine (other than an Engine or Spare Engine) as the result of such engine being installed on such Airframe.

Any Wet Lease or similar arrangement under which the Company maintains operational control of the relevant Aircraft shall not constitute a delivery, transfer or relinquishment of possession for purposes of this Section 3.02. The Collateral Agent acknowledges that any consolidation or merger of the Company or conveyance, transfer or lease of all or substantially all of the Company’s assets permitted by the Operative Documents shall not be prohibited by this Section 3.02.

(c) Operation and Use. So long as any Aircraft, any Airframe, any Engine or any Spare Engine is subject to the Lien of this C Mortgage, the Company shall not (or permit any Permitted Lessee to) operate, use or locate any Aircraft, any Airframe, any Engine or any Spare Engine, or allow any Aircraft, any Airframe, any Engine or any Spare Engine to be operated, used or located, (i) in any area excluded from coverage by any insurance required by the terms of Section 3.06, except in the case of a requisition by the U.S. Government where the Company obtains indemnity in lieu of such insurance from the U.S. Government or insurance from the U.S. Government against substantially the same risks and for at least the amounts of the insurance required by Section 3.06 covering such area, or (ii) in any recognized area of hostilities unless covered in accordance with Section 3.06 by war risk insurance, or in either case unless such Aircraft, Airframe, Engine or Spare Engine is only temporarily operated, used or located in such area as a result of an emergency, equipment malfunction, navigational error, hijacking, weather condition or other similar unforeseen circumstance, so long as the Company diligently and in good faith proceeds to remove such Aircraft, Airframe, Engine or Spare Engine from such area. The Company shall also have the right to operate any Aircraft without having on board the original registration certificate or airworthiness certificate in the event that either or both such certificates disappear from such Aircraft, but only to the extent permitted by Exemption No. 5318 of the FAA Regulations or other similar exemption. So long as any Aircraft, any Airframe, any Engine or any Spare Engine is subject to the Lien of this C Mortgage, the Company shall not permit such Aircraft, Airframe, Engine or Spare Engine, as the case may be, to be used, operated, maintained, serviced, repaired or overhauled (x) in violation of any Law of any Government Entity having jurisdiction that is binding on or applicable to such Aircraft, Airframe, Engine or Spare Engine or (y) in violation of any airworthiness certificate, license or registration of any such Government Entity relating to such Aircraft, Airframe, Engine or Spare Engine, except (i) immaterial or non-recurring violations with respect to which corrective measures are taken promptly by the Company or Permitted Lessee, as the case may be, upon discovery thereof, (ii) to the extent the validity or application of any such Law or requirement relating to any such certificate, license or registration is being contested in good faith by the

[C Mortgage and Security Agreement]

Company or Permitted Lessee in any reasonable manner which does not materially adversely affect the Lien of this C Mortgage and does not involve any material risk of sale, forfeiture or loss of such Aircraft, Airframe, Engine or Spare Engine, or (iii) that the Company shall not be in default under, or required to take any action set forth in this sentence if it is not possible for the Company to comply with the laws of a jurisdiction other than the United States (or other jurisdiction in which such Aircraft is registered) because of a conflict with the applicable laws of the United States (or such other jurisdiction where such Aircraft is registered).

(d) Registration. The Company, on or prior to each Closing Date, shall cause each Aircraft to be duly registered with the FAA in its name under the Act and except as otherwise permitted by this Section 3.02(d) at all times thereafter shall cause such Aircraft to remain so registered. So long as no Special Default or Event of Default shall have occurred and be continuing, the Company may at any time, subject to Annex C hereto, cause such Aircraft to be re-registered under the laws of a country other than the United States. Whether or not a Special Default or an Event of Default shall be continuing, subject to Annex C hereto, Company may at any time cause such Aircraft to be re-registered under the laws of the United States. Unless the C Mortgage has been discharged, the Company shall also cause the C Mortgage to be duly recorded and at all times maintained of record as a valid first-priority perfected mortgage (subject to Permitted Liens) on each Aircraft, each Airframe and each of the Engines and, if applicable, any Spare Engines (except to the extent (i) such perfection or priority cannot be maintained solely as a result of the failure by Collateral Agent to execute and deliver any necessary documents or (ii) in the case of a registration of an Aircraft in a country other than the United States, the C Mortgage need not be so recorded as provided in Annex C hereto). Unless the Lien of this C Mortgage has been discharged, the Company shall cause the International Interest granted under this C Mortgage in favor of the Collateral Agent with respect to each Airframe and each Engine and Spare Engine to be registered with the International Registry, subject to the Collateral Agent providing its consent to such registration.

(e) Markings. If permitted by applicable Law, on or as soon as practicable after the Closing Date, the Company will cause to be affixed to, and maintained in, the cockpit of each Airframe and on each Engine and Spare Engine, in each case, in a clearly visible location, a placard of a reasonable size and shape bearing the legend: “Subject to a Security Interest in favor ▇▇▇▇▇ Fargo Bank Northwest, National Association, not in its individual capacity but solely as Collateral Agent.” Such placards may be removed temporarily, if necessary, in the course of maintenance of the Airframes or Engines or Spare Engines. If any such placard is damaged or becomes illegible, the Company shall promptly replace it with a placard complying with the requirements of this Section 3.02(e). Except as above provided, the Company will not allow the name of any person (other than the Company) to be placed on any Airframe or on any Engine or Spare Engine as a designation that might be interpreted as a claim of ownership, provided that nothing herein shall prohibit the Company or any Permitted Lessee from placing its customary colors and insignia on any Airframe and any Engine or any Spare Engine. If the Collateral Agent is replaced or its name is changed, the Company shall replace such placards with new placards reflecting the correct name of the Collateral Agent promptly after the Company receives notice of such replacement or change and, if resulting from a replacement by the Holders of the Collateral Agent not for cause, advancement from the Holders of its reasonable costs of making such replacement.

[C Mortgage and Security Agreement]

Section 3.03. Inspection.

(a) At all reasonable times and upon reasonable advance notice (taking into consideration the availability of an Aircraft or Spare Engine, as the case may be, and the Company (or Permitted Lessee) personnel), so long as such Aircraft, or Spare Engine, as the case may be, is subject to the Lien of this C Mortgage, 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 such Aircraft, Airframe, Engines and Spare Engines (including without limitation, the Aircraft Documents or Spare Engine Documents, as the case may be) and any such Inspecting Party may make copies of such Aircraft Documents or Spare Engine Documents, as the case may be, not reasonably deemed confidential by the Company or such Permitted Lessee.

(b) Any inspection of an Aircraft, Airframe, Engine or Spare Engine hereunder shall be subject to Company’s safety and security rules applicable at the location of such Aircraft and Spare Engine and shall be limited to a visual, walk-around inspection and shall not include the opening of any panels, bays or other components of such Aircraft and Spare Engine without the express consent of the Company (such consent not to be given by the Collateral Agent pursuant to the power of attorney granted herein), and no such inspection shall interfere with the Company’s or any Permitted Lessee’s maintenance and operation of the Aircraft, Airframes and Engines and Spare Engines.

(c) 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 visit, inspection or survey.

(d) Each Inspecting Party shall bear its own expenses in connection with any such inspection (including the cost of any copies made in accordance with Section 3.03(a)); provided that all such expenses incurred while an Event of Default shall have occurred shall be paid by the Company.

[C Mortgage and Security Agreement]

any and all disclosures permitted by clauses (C) and (D) above shall be made only to the extent necessary to meet the specific requirements or needs of Persons for whom such disclosures are hereby permitted.

Section 3.04. Maintenance; Replacement and Pooling of Parts, Alterations, Modifications and Additions; Substitution of Engines.

(a) Maintenance. The Company shall, at its own cost and expense, (1) maintain, service, repair, and overhaul (or cause to be maintained, serviced, repaired, and overhauled) each Aircraft (and any engine which is not an Engine but which is installed on such Aircraft) and Spare Engine (A) so as to keep such Aircraft and Spare Engine in as good an operating condition as when delivered to the Company (ordinary wear and tear excepted and without taking into consideration hours and cycles) and so as to keep such Aircraft in such condition as may be necessary to enable the airworthiness certification for such Aircraft to be maintained in good standing at all times under the Act (or under the applicable requirements of another Aviation Authority in the jurisdiction in which such Aircraft is registered) except (i) when such Aircraft is being temporarily stored, (ii) when such Aircraft is being serviced, repaired, maintained, overhauled, tested or modified as permitted or required by the terms of this C Mortgage, (iii) when aircraft similar to such Aircraft have been grounded by the FAA or under the applicable laws of any other jurisdiction in which such Aircraft is registered, or such authority has revoked or suspended the airworthiness certificates for such aircraft, or (iv) (x) for immaterial or non-recurring violations with respect to which corrective measures are taken promptly by Company or Permitted Lessee, as the case may be, upon discovery thereof, or (y) to the extent the validity or application of any such Law or requirement relating to any such certificate, license or registration is being contested in good faith by Company or Permitted Lessee in any reasonable manner which does not materially adversely affect the Lien of this C Mortgage and does not involve any material risk of sale, forfeiture or loss of such Aircraft, and (B) in accordance with the Maintenance Program for such Aircraft and utilizing the same or better manner of maintenance used by the Company (or any Permitted Lessee) with respect to similar aircraft operated by it, and (2) maintain or cause to be maintained in English all records, logs and other materials required to be maintained in respect of such Aircraft by the FAA or the applicable Aviation Authority. In any case, such Aircraft will be maintained in accordance with the maintenance standards required by or substantially similar to those required by the FAA or the central aviation authority of Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Ireland, Italy, Japan, the Netherlands, New Zealand, Norway, Spain, Sweden, Switzerland or the United Kingdom. Determination of the appropriate course of action in maintenance, including the means of compliance with airworthiness directives, and all other matters pertaining to each Aircraft will be within the sole discretion of the Company.

(b) Replacement of Parts. The Company, at its own cost and expense, will, or will cause a Permitted Lessee to, at its own cost and expense, promptly replace or cause to be replaced all Parts which may from time to time become worn out, lost, stolen, destroyed, seized, confiscated, damaged beyond repair or permanently rendered unfit for use for any reason whatsoever, except as otherwise provided in Sections 3.04(c) and 3.04(d). In addition, the Company may, at its own cost and expense, and may permit a Permitted Lessee, at its own cost

[C Mortgage and Security Agreement]

and expense, (or any maintenance provider for the Aircraft) to, remove (or cause to be removed) in the ordinary course of maintenance, service, repair, overhaul or testing, any Parts, whether or not worn out, lost, stolen, destroyed, seized, confiscated, damaged beyond repair or permanently rendered unfit for use; provided that the Company, except as otherwise provided herein, will, at its own cost and expense, replace, or cause to be replaced, such Parts as promptly as practicable. All replacement parts (other than replacement parts temporarily installed as provided in Section 3.04(c) hereof) shall be free and clear of all Liens (except Permitted Liens), and shall be in as good an operating condition as, and shall have a value and utility substantially equal to, the Parts replaced, assuming such replaced Parts were in the condition and repair required to be maintained by the terms hereof (but without taking into consideration hours and cycles remaining until overhaul). Except as provided in Section 3.04(d), all Parts at any time removed from any Airframe or any Engine or any Spare Engine shall remain subject to the Lien of this C Mortgage, no matter where located, until such time as such Parts shall be replaced by parts which meet the requirements for replacement parts specified above. Upon any replacement part becoming incorporated or installed in or attached to any Airframe or any Engine or any Spare Engine, without further act (subject only to Permitted Liens and any arrangement permitted by Section 3.04(c) hereof), (i) such replacement part shall become subject to the Lien of this C Mortgage and be deemed a Part for all purposes hereof to the same extent as the Parts originally incorporated or installed in or attached to such Airframe, Engine or Spare Engine and (ii) the replaced Part shall no longer be subject to the Lien of this C Mortgage and shall no longer be deemed a Part hereunder. Upon request of Company, the Collateral Agent shall, at Company’s expense, execute and deliver to Company such documents as may be reasonably required to evidence the release of any replaced Part from the Lien of this C Mortgage.

(c) Pooling of Parts; Temporary Replacement Parts. Any Part removed from any Airframe or any Engine or any Spare Engine may be subjected by the Company (or any Permitted Lessee) to a normal pooling arrangement customary in the airline industry and entered into in the ordinary course of business of Company or Permitted Lessee; provided that the part replacing such removed Part shall be incorporated or installed in or attached to such Airframe or Engine or Spare Engine in accordance with Section 3.04(b) hereof as promptly as practicable after the removal of such removed Part. In addition, the Company (or any Permitted Lessee) may use temporary parts or pooled parts on any Aircraft that are owned by a third party subject to a pooling arrangement as temporary replacements for Parts, provided that the Company (or any Permitted Lessee) as promptly thereafter as practicable, either (1) causes such pooled or temporary replacement part to become subject to the Lien of this C Mortgage free and clear of all Liens other than Permitted Liens or (2) replaces such replacement part with a further replacement part owned by the Company (or any Permitted Lessee) which meets the requirements of Section 3.04(b) hereof and which shall become subject to the Lien of this C Mortgage, free and clear of all Liens other than Permitted Liens.

(d) Alterations, Modifications and Additions. The Company shall, or shall cause a Permitted Lessee to, at its own cost and expense, make (or cause to be made) such alterations, modifications and additions to the Airframes, Engines and Spare Engines as may be required from time to time to meet the applicable standards of the FAA or any other Aviation Authority having jurisdiction over the operation of any Aircraft, to the extent made mandatory in

[C Mortgage and Security Agreement]

respect of such Aircraft or Spare Engine, except for (i) immaterial or non-recurring violations with respect to which corrective measures are taken promptly by the Company or a Permitted Lessee, as the case may be, upon discovery thereof, or (ii) to the extent the validity or application of any such Law or requirement is being contested in good faith by the Company or a Permitted Lessee in any reasonable manner which does not involve any material risk of sale, loss or forfeiture of such Aircraft or Spare Engine and does not materially adversely affect the Lien of this C Mortgage. In addition, the Company may, or may permit a Permitted Lessee at its own cost and expense to, from time to time alter the passenger (seating) configuration of any Aircraft and may make or cause to be made such alterations and modifications in and additions to any Airframe, Engine or Spare Engine as the Company (or any Permitted Lessee) may deem desirable in the proper conduct of its business, including removal of Parts which the Company (or any Permitted Lessee) deems to be obsolete or no longer suitable or appropriate for use on such Airframe, Engine or Spare Engine (such parts, “Obsolete Parts”); provided that no such alteration, modification, removal or addition impairs the condition or airworthiness of such Airframe, Engine or Spare Engine, or materially diminishes the value, utility and, in regard to any Airframe, remaining useful life (without regard to hours and cycles) of such Airframe or such Engine or Spare Engine below the value, utility or remaining useful life (without regard to hours and cycles) thereof immediately prior to such alteration, modification, removal or addition, assuming that such Airframe or such Engine or Spare Engine is in the condition required hereunder. In addition, the value (but not the utility, condition or airworthiness) of any Airframe or any Engine or Spare Engine may be reduced by the value, if any, of Obsolete Parts which shall have been removed. All parts incorporated or installed in or attached or added to an Airframe, Engine or Spare Engine as the result of such alteration, modification or addition (except those parts which are excluded from the definition of Parts or which the Company has leased from others and Parts which may be removed by the Company pursuant to the next sentence) (the “Additional Part” or “Additional Parts”) shall be free and clear of any Liens other than Permitted Liens and shall, without further act, become subject to the Lien of this C Mortgage. Notwithstanding the foregoing, Company may remove (and not replace) any Additional Part, provided that such Additional Part (i) is in addition to, and not in replacement of or substitution for, any Part originally incorporated or installed in or attached to any Airframe or any Engine or Spare Engine at the time of delivery thereof hereunder or any Part in replacement of or substitution for any such Part, (ii) is not required to be incorporated or installed in or attached or added to any Airframe or any Engine or Spare Engine pursuant to the terms of Section 3.04(a) or the first sentence of this Section 3.04(d), and (iii) can be removed from such Airframe or such Engine or Spare Engine without impairing the airworthiness of such Airframe or such Engine or Spare Engine or materially diminishing the value, utility and remaining useful life of such Airframe or such Engine or Spare Engine which such Airframe or such Engine or Spare Engine would have had at such time had such alteration, modification or addition not occurred. Upon the removal thereof as provided above, such Additional Parts shall no longer be subject to the Lien of this C Mortgage or be deemed part of the Airframe or Engine from which it was removed. Notwithstanding any other provision of this Indenture, the Company may, at any time, install or permit to be installed in the Aircraft Passenger Convenience Equipment owned by the Company or any Permitted Lessee or by third parties and leased or otherwise furnished to the Company in the ordinary course of business, and the Company may remove (and not replace) or permit to be removed (and not replaced) the same, and Collateral Agent shall not acquire a Lien thereon by virtue of such installation or otherwise, and the rights of the owners therein shall not constitute a default under this C Mortgage.

[C Mortgage and Security Agreement]

(e) Substitution of Engines. Upon the occurrence of an Event of Loss with respect to (I) an Engine under circumstances in which an Event of Loss with respect to an Airframe has not occurred or (II) a Spare Engine, the Company shall promptly (and in any event within 15 days after such occurrence) give the Collateral Agent written notice of such Event of Loss. The Company shall have the right at its option at any time, on at least five (5) Business Days’ prior notice to the Collateral Agent, to substitute, and if an Event of Loss shall have occurred with respect to (I) an Engine under circumstances in which an Event of Loss with respect to an Airframe has not occurred or (II) a Spare Engine, shall, but subject to Section 2.15 of the Indenture, within 60 days of the occurrence of such Event of Loss substitute, a Replacement Engine for any Engine or Spare Engine, as the case may be. In such event, immediately upon the effectiveness of such substitution and without further act, (i) the replaced Engine or Spare Engine, as the case may be, shall thereupon be free and clear of all rights of the Collateral Agent and the Lien of this C Mortgage and shall no longer be deemed an Engine or Spare Engine, as the case may be, hereunder and (ii) such Replacement Engine shall become subject to this C Mortgage free and clear of all Liens (other than Permitted Liens) and be deemed an “Engine” or “Spare Engine” as the case may be, for all purposes hereof to the same extent as the replaced Engine or Spare Engine, as the case may be. Such Replacement Engine shall be an engine manufactured by Engine Manufacturer that is the same model as the Engine, or Spare Engine, as the case may be, to be replaced thereby, or an improved model, and that is suitable for installation and use on the relevant Airframe (in the case of an Engine), and that has a value and utility (without regard to hours and cycles remaining until overhaul) at least equal to, and be in as good operating condition and repair as, the Engine, or Spare Engine, as the case may be, to be replaced thereby (assuming that such Engine or Spare Engine had been maintained in accordance with this C Mortgage). The Company’s substitution hereunder shall be subject to (x) the satisfaction of each of the requirements set forth in Section 4.11 of the Indenture, including, without limitation, each requirement for a Replacement Engine to be Collateral and each of the requirements of Section 4.11(a)(v) and (y) the fulfillment (which may be simultaneous with such replacement) of the following conditions precedent at the Company’s sole cost and expense, and the Collateral Agent agrees to cooperate with the Company to the extent necessary to enable it to timely satisfy such conditions:

(C) UCC financing statements and registrations with the International Registry covering the security interests created by this C Mortgage (or any similar statements or other documents required to be filed or delivered pursuant to the laws of the jurisdiction in which such Aircraft may be registered) as are deemed necessary or desirable by counsel for the Collateral Agent to protect the security interests of the Collateral Agent in the Replacement Engine;

(ii) the Company shall cause to be delivered to the Collateral Agent such evidence of compliance with the insurance provisions of Section 3.06 with respect to such Replacement Engine as Collateral Agent shall reasonably request;

(iii) the Company shall have furnished to Collateral Agent (A) an opinion of counsel to the Company, or other counsel satisfactory to the Collateral Agent, addressed to the Collateral Agent, to the effect that the Replacement Engine has or have duly been made subject to the Lien of this C Mortgage, and Collateral Agent will be entitled to the benefits of Section 1110 with respect to the Replacement Engine provided that such opinion with respect to Section 1110 need not be delivered to the extent that immediately prior to such replacement the benefits of Section 1110 were not, solely by reason of a change in law or court interpretation thereof, available to Collateral Agent, and (B) an opinion of Company’s aviation law counsel reasonably satisfactory to Collateral Agent and addressed to Collateral Agent as to the due filing for recordation of the C Mortgage Supplement with respect to such Replacement Engine under the Act or such other applicable law of the jurisdiction other than the United States in which such Aircraft is registered in accordance with Section 3.02(d), as the case may be, and the registration with the International Registry of (i) the International Interest granted under such C Mortgage Supplement with respect to such Replacement Engine and (ii) if the ▇▇▇▇ of sale referred to in clause (i)(B) above constitutes “contract of sale” under the Cape Town Convention, such contract of sale with respect to such Replacement Engine; and

(iv) the Company shall have furnished to Collateral Agent a certificate of a qualified aircraft engineer (who may be an employee of the Company) certifying that such Replacement Engine has a value and utility and remaining useful life (without regard to hours and cycles remaining until overhaul) at least equal to the Engine so replaced (assuming that such Engine or Spare Engine, as the case may be, had been maintained in accordance with this C Mortgage).

Upon satisfaction of all conditions to such substitution, (x) the Collateral Agent shall execute and deliver to the Company such documents and instruments, prepared at the Company’s expense, as the Company shall reasonably request to evidence the release of such replaced Engine or Spare Engine, as the case may be, from the Lien of this C Mortgage, (y) the Collateral Agent shall assign to the Company all claims it may

[C Mortgage and Security Agreement]

have against any other Person relating to any Event of Loss giving rise to such substitution and (z) the Company shall receive all insurance proceeds (other than those reserved to others under Section 3.06(b)) and other proceeds in respect of any Event of Loss giving rise to such replacement in accordance with Section 3.05(d) hereof.

Nevertheless, if so requested by the Collateral Agent or any purchaser, the Company 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.

(c) Collateral Agent agrees that if Company requests a change of registration pursuant to Section 3.02(c) of the C Mortgage and this Annex C, it will take all such action reasonably requested by Company in order to effect such a change in registration, including the execution and delivery of such documents and instruments as may be necessary or advisable in connection therewith; and
