In view of the foregoing provisions of this paragraph, the Company hereby waives the provisions of Article XVI(1)(a) of the Protocol.

TO HAVE AND TO HOLD the Collateral unto the Administrative Agent, its permitted successors and assigns, forever, upon the terms herein set forth, in trust for the benefit, security and protection of the Secured Parties, without any priority of any Loan, Note or Obligation over any other except as may be separately agreed among the Secured Parties and such other secured parties or as provided herein, and for the uses and purposes and subject to the terms and provisions set forth in this Mortgage.

It is expressly agreed that anything herein contained to the contrary notwithstanding, the Company shall remain liable under each of the Financing Documents to which it is a party to perform all of the obligations assumed by it thereunder, all in accordance with and pursuant to the terms and provisions thereof, and neither the Administrative Agent nor any Secured Party shall have any obligation or liability under any of the Financing Documents to which the Company is a party by reason of or arising out of the assignment hereunder, nor shall the Administrative Agent or any Secured Party be required or obligated in any manner to perform or fulfill any obligations of the Company under any of the Financing Documents to which the Company is a party, or, except as herein expressly provided, to make any payment, or to make any inquiry as to the nature or sufficiency of any payment received by it, or present or file any claim, or take any action to collect or enforce the payment of any amounts that may have been assigned to it or to which it may entitled at any time or times.

The Company does hereby irrevocably constitute and appoint the Administrative Agent the true and lawful attorney of the Company (which appointment is coupled with an interest) with full power (in the name of the Company or otherwise) to ask, require, demand, receive, compound and give acquittance for any and all moneys and claims for moneys (in each case including insurance and requisition proceeds) and all other property that now or hereafter constitutes part of the Collateral, to endorse any checks or other instruments or orders in connection therewith and to file any claims or to take any action or to institute any proceeding that the Administrative Agent may deem to be necessary or advisable in the premises; provided that the Administrative Agent shall not exercise any such rights except upon the occurrence and during the continuance of an Event of Default.

The Company agrees that at any time and from time to time, upon the written request of the Administrative Agent, the Company will promptly and duly execute and deliver or cause to be duly executed and delivered any and all such further instruments and documents as the Administrative Agent may reasonably request to obtain the full benefits of the assignment hereunder and of the rights and powers herein granted.

The Company does hereby warrant and represent that it has not assigned or pledged (except any assignment or pledge that has been terminated on or prior to the date hereof) and hereby covenants that it will not assign or pledge, so long as the assignment hereunder shall remain in effect, any of its right, title or interest hereby assigned, to anyone other than the Administrative Agent except to the extent permitted by the Term Loan Agreement.

The Administrative Agent acknowledges and agrees that notwithstanding anything to the contrary herein set forth, the Company may at any time during the term of this Mortgage install a

telephone system and/or an inflight entertainment system for passenger use on any Aircraft (collectively, the “Inflight Equipment”) provided that in the case of Inflight Equipment which is owned by a third party and leased to the Company:

(a) the owner or financier of the Inflight Equipment will have no Lien on or against such Aircraft and no rights with respect to such Aircraft except the right to remove the Inflight Equipment from such Aircraft if such owner, financier or the Company repairs and restores such Aircraft as provided below;

(b) such right of installation and removal is subject to and conditional upon any such owner or financier repairing any damage to the Aircraft in connection therewith and paying (and holding the Agents and the other Secured Parties harmless with respect to) all costs, expenses and liabilities in connection therewith; and

(c) prior to the installation of any such Inflight Equipment, the Company shall provide the Administrative Agent with the identity and notice particulars of the owner or financier of such Inflight Equipment. The Administrative Agent acknowledges that, whether or not the requirements of this Section 2.2 are satisfied in full, at all times (i) the leased Inflight Equipment will not constitute a Part or a part of such Aircraft, and (ii) the leased Inflight Equipment will not become subject to the Lien of this Mortgage.

ARTICLE III

COVENANTS OF THE COMPANY

Section 3.1. [Intentionally left blank].

Section 3.2. Lease. Lessee agrees that it shall cause any Lease or Wet Lease of more than six (6) months duration (or, if an Event of Default is continuing, any Lease or Wet Lease regardless of its duration) to be assigned to Administrative Agent at the time such Lease or Wet Lease is entered into pursuant to a Lease Assignment substantially in the form of Exhibit B hereto with such changes as may be requested by Company, the consent of Administrative Agent not to be unreasonably withheld, at least ten (10) days before the intended date of execution thereof. In connection therewith the Company shall cause (subject to the consent of the Administrative Agent) an Assignment of such Lease or Wet Lease to be registered with the International Registry, and in addition shall take such additional actions as are required under Section 5.18 of the Term Loan Agreement.

Section 3.3. Identification of Security Interest; Filings.

(a) As soon as practicable after the date hereof but no later than 60 days after the Closing Date, the Company agrees to affix and maintain (or cause to be affixed and maintained), at its expense, in the cockpit of the Airframe adjacent to the airworthiness certificate therein and on each Engine a nameplate bearing the inscription:

“SUBJECT TO A MORTGAGE AND SECURITY AGREEMENT IN FAVOR OF JPMORGAN CHASE BANK, N.A., AS ADMINISTRATIVE AGENT”

(such nameplate to be replaced, if necessary, with a nameplate reflecting the name of any successor Administrative Agent). Except as above provided or as may be required by Law, the Company will not allow the name of any Person (other than the Company) to be placed on the Airframe or on any Engine as

a designation that might be interpreted as a claim of security interest or ownership and will remove any such existing designation no later than the time such nameplate is affixed; provided that nothing herein contained shall prohibit the Company (or any Lessee) from placing its customary colors and insignia on the Airframe or any Engine.

(b) The Company will take, or cause to be taken, at the Company’s cost and expense, such action with respect to the recording, filing, re-recording and re-filing of this Mortgage, each Mortgage Supplement and each Lease Assignment, and any financing statements or other instruments as are reasonably requested by the Administrative Agent to maintain, so long as this Mortgage is in effect, the perfection of the Lien created by this Mortgage and the other Collateral Documents, or at the request of the Administrative Agent, will furnish to the Administrative Agent such instruments, in execution form, and such other information as may be reasonably requested by the Administrative Agent to enable the Administrative Agent to take such action.

ARTICLE IV

REMEDIES OF THE ADMINISTRATIVE AGENT

UPON AN EVENT OF DEFAULT

Section 4.1. Event of Default. For purposes of the Cape Town Convention, a “default” means any Event of Default.

Section 4.2. Remedies with Respect to Collateral.

(a) Remedies Available.

Upon the occurrence of any Event of Default and at any time thereafter so long as the same shall be continuing, this Mortgage shall be in default and the Administrative Agent (in accordance with the provisions of Article 5) may, and upon the written instructions of the Required Lenders shall, do one or more of the following:

(A) cause the Company, upon the written demand of the Administrative Agent, at the Company’s expense, to deliver promptly, and the Company shall deliver promptly, all or such part of the Airframe or any Engine or other Collateral as the Administrative Agent may so demand to the Administrative Agent or its order, or the Administrative Agent, at its option, may enter upon the premises where all or any part of the Airframe or any Engine or other Collateral are located and take immediate possession (to the exclusion of the Company and all Persons claiming under or through the Company) of and remove the same by summary proceedings or otherwise together with any engine that is not an Engine but which is installed on the Airframe, subject to all of the rights of the owner, lessor, lienor or secured party of such engine; provided that such engine shall be held for the account of any such owner, lessor, lienor or secured party or, if owned by the Company, may at the option of the Administrative Agent, be exchanged with the Company for an Engine;

(B) sell all or any part of the Airframe and any Engine or other Collateral at public or private sale, whether or not the Administrative Agent shall at the time have possession thereof, as the Administrative Agent may determine, or lease or otherwise dispose of all or any part of the Airframe or such Engine or

other Collateral as the Administrative Agent, in its sole discretion, may determine, all free and clear of any rights or claims of whatsoever kind of the Company, provided the same is conducted in accordance with applicable law; or

(C) exercise any or all of the rights and powers and pursue any and all remedies of a secured party under applicable law, including, without limitation, the Uniform Commercial Code of the State of New York.

Upon every taking of possession of Collateral under this Section 4.2, the Administrative Agent may, from time to time, at the expense of the Administrative Agent, make all such expenditures for maintenance, insurance, repairs, replacements, alterations, additions and improvements to and of the Collateral, as it may deem proper. In each such case, the Administrative Agent shall have the right to maintain, store, lease, control or manage the Collateral and to exercise all rights and powers of the Company relating to the Collateral in connection therewith, as the Administrative Agent shall deem prudent, including the right to enter into any and all such agreements with respect to the maintenance, insurance, storage, leasing, control, management or disposition of the Collateral or any part thereof as the Administrative Agent may determine; and the Administrative Agent shall be entitled to collect and receive directly all tolls, rents, revenues, issues, income, products and profits of the Collateral and every part thereof, without prejudice, however, to the right of the Administrative Agent under any provision of this Mortgage to collect and receive all cash held by, or required to be deposited with, the Administrative Agent hereunder. Such tolls, rents, revenues, issues, income, products and profits shall be applied to pay the expenses of storage, leasing, control, management or disposition of the Collateral, and of all maintenance, repairs, replacements, alterations, additions and improvements, and to make all payments that the Administrative 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 the Company), and all other payments that the Administrative Agent may be required or authorized to make under any provision of this Mortgage, as well as just and reasonable compensation for the services of the Administrative Agent, and of all Persons properly engaged and employed by the Administrative Agent.

In addition, the Company shall be liable for all reasonable legal fees and other reasonable out-of-pocket costs and expenses incurred by reason of the occurrence of any Event of Default or the exercise of the Administrative Agent’s remedies with respect thereto, including all costs and expenses incurred in connection with the retaking or return of the Airframe or any Engine in accordance with the terms hereof or under applicable law, including, without limitation, the Uniform Commercial Code of the State of New York, which amounts shall, until paid, be secured by the Lien of this Mortgage.

If an Event of Default shall have occurred and be continuing and the Loans shall have been accelerated pursuant to Section 7 of the Term Loan Agreement, at the request of the Administrative Agent the Company shall promptly execute and deliver to the Administrative Agent such instruments of title and other documents as the Administrative Agent may reasonably request to enable the Administrative Agent or an agent or representative designated by the Administrative Agent, at such time or times and place or places as the Administrative Agent may specify, to obtain possession of all or any part of the Collateral to which the Administrative Agent shall at the time be entitled hereunder. If the Company shall for any reason fail to execute and deliver such instruments and documents after such request by the Administrative Agent, the Administrative Agent may obtain a judgment conferring on the Administrative Agent the right to immediate possession and requiring the Company to execute and deliver such instruments and documents to the Administrative Agent, to the entry of which judgment the Company hereby specifically consents to the fullest extent it may lawfully do so.

Nothing in the foregoing shall affect the right of each Secured Party to receive all payments of principal of, and interest on, the Loans held by such Secured Party and all other amounts owing to such Secured Party as and when the same may be due.

(b) Notice of Sale.

The Administrative Agent shall give the Company at least fifteen (15) days’ prior written notice of the date fixed for any public sale of the Airframe or any Engine or of the date on or after which any private sale will be held, which notice the Company hereby agrees is reasonable notice, and any such public sale shall be conducted in general so as to afford the Company (and any Lessee) a reasonable opportunity to bid.

If any Event of Default shall occur and be continuing, to the extent permitted by law, the Administrative Agent shall be entitled, as a matter of right as against the Company, without notice or demand and without regard to the adequacy of the security for the Loans or the solvency of the Company, upon the commencement of judicial proceedings by it to enforce any right under this Mortgage, to the appointment of a receiver of the Collateral and of the tolls, rents, revenues, issues, income, products and profits thereof.

(d) Concerning Sales.

At any sale under this Article, any Secured Party or the Administrative Agent may bid for and purchase the property offered for sale, may make payment on account thereof as herein provided, and, upon compliance with the terms of sale, may hold, retain and dispose of such property without further accountability therefor. Any purchaser shall be entitled, for the purpose of making payment for the property purchased, to surrender for the cancellation, all or any part of the Loan (and any Notes evidencing the same) in lieu of cash in the amount that shall be payable thereon as principal and/or accrued interest. In the event that amounts due on any Loan exceed the amounts being surrendered as aforesaid, such Loan shall be returned to the Secured Parties making such surrender after being stamped or endorsed to show partial cancellation.

Section 4.3. Waiver of Appraisement, etc., Laws.

To the full extent that it may lawfully so agree, the Company agrees that it will not at any time insist upon, plead, claim or take the benefit or advantage of, any appraisement, valuation, stay, extension, or redemption law now or hereafter in force, in order to prevent or hinder the proper enforcement of this Mortgage or the absolute sale of the Collateral as permitted hereunder, or any part thereof, or the possession thereof by any purchaser at any proper sale under this Article; but the Company, for itself and all who may claim under it, so far as it or they now or hereafter lawfully may, hereby waives the benefit of all such laws. The Company, for itself and all who may claim under it, waives, to the extent that it lawfully may, all right to have the property in the Collateral marshaled upon any foreclosure hereof, and agrees that any court having jurisdiction to foreclosure this Mortgage may order the sale of the Collateral as an entirety.

Section 4.4. Remedies Cumulative.

Subject to the provisions of Section 4.6 below, each and every right, power and remedy herein specifically given to the Administrative Agent or otherwise in this Mortgage shall be cumulative and shall be in addition to every other right, power and remedy herein specifically given or now or

hereafter existing in the Financing Documents or 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 Administrative 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 time or thereafter any other right, power or remedy. No delay or omission by the Administrative 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 the Company or to be an acquiescence therein. Notwithstanding the foregoing, nothing herein shall be deemed to permit duplicative recovery by Administrative Agent or any Secured Party of any amount due and owing to it hereunder or under any other Financing Document.

Section 4.5. Discontinuance of Proceedings.

If the Administrative Agent shall have proceeded to enforce any right, power or remedy under this Mortgage by foreclosure, entry or otherwise, and such proceedings shall have been discontinued or abandoned for any reason, then and in every such case the Company and the Administrative Agent shall be restored to their former positions and rights hereunder with respect to the property, subject to the Lien of this Mortgage, and all rights, remedies and powers of the Administrative Agent shall continue, as if no such proceedings had been undertaken (but otherwise without prejudice).

Section 4.6. Concerning the Cape Town Convention.

Without limiting the foregoing, the parties agree that (x) in addition to the remedies set forth in this Article IV or otherwise available to Administrative Agent under this Mortgage and the other Financing Documents, at law or in equity, upon the occurrence and during the continuation of an Event of Default, the Administrative Agent may, but shall not be obligated to, exercise any remedy available to it under the Cape Town Convention (subject, in each case to the requirements and limitations of the Cape Town Convention), including the remedies set forth in Articles 8, 9 and 34 of the Cape Town Convention, but excluding the (a) procurement of the de-registration of the Aircraft (if the Aircraft is registered with the FAA or any successor agency thereto) and the export and physical transfer of the Aircraft or any Engine from the territory (if from a territory within the territorial limits of the United States) in which it is situated pursuant to Article IX of the Protocol (without prejudice to the applicability of other applicable law), and (b) solely to the extent permitted by Article 15 of the Cape Town Convention, the provisions of Chapter III of the Cape Town Convention with regard to default remedies, provided that such exclusion in this clause (b) shall not be applicable (to the extent permitted by Article 15 of the Cape Town Convention) to the extent such default remedies are exercised outside the territorial limits of the United States and in a manner not involving the courts of the United States or of its territorial units; and

(y) where a remedy is available to it under the Cape Town Convention and also under this Agreement and the other Financing Documents or other applicable law, to the extent permitted by the Cape Town Convention and other applicable law, and subject to the provisions of the previous clause (x), the Administrative Agent may elect under which of the foregoing it shall exercise such remedy.

ARTICLE V

DUTIES OF THE ADMINISTRATIVE AGENT

Section 5.1. Action Upon Event of Default.

Subject to the terms of Sections 4.2 and 5.3, the Administrative Agent shall take such action, or refrain from taking such action, with respect to an Event of Default (including with respect to the exercise of any rights or remedies under the Collateral Documents) as it may deem advisable in the best interests of the Lenders or as shall be instructed in writing by the Required Lenders. The Administrative Agent may, but shall not be obligated to, take such action, or refrain from taking such action, under or with respect to the Collateral Documents and with respect to such Event of Default as it shall determine to be advisable in the best interests of the Secured Parties.

Section 5.2. [Intentionally left blank].

Section 5.3. Indemnification.

The Administrative Agent shall not be required to take any action or refrain from taking any action under Section 5.1 or Article 4 if it shall have reasonable grounds for believing that repayment of any funds expended by it or adequate indemnification against any risks incurred in connection therewith is not reasonably assured to it. The Administrative Agent shall not be required to take any action under Section 5.1 or Article 4, nor shall any other provision of any Collateral Document be deemed to impose a duty on the Administrative Agent to take any action, if the Administrative Agent shall have been advised in writing by independent counsel that such action is contrary to the terms hereof or is otherwise contrary to law.

Section 5.4. No Duties Except as Specified in Collateral Documents or Instructions.

The Administrative Agent shall not have any duty or obligation to manage, control, use, sell, operate, store, dispose of or otherwise deal with the Aircraft or any other part of the Collateral, or to otherwise take or refrain from taking any action under, or in connection with, any Collateral Document, except as expressly provided by the terms thereof; and no implied duties or obligations shall be read into any Collateral Document against the Administrative Agent. The Administrative Agent nevertheless agrees that it will, at its own cost and expense, promptly take such action as may be necessary duly to discharge any Liens on any part of the Collateral, or on any properties of the Company assigned, pledged or mortgaged under the Collateral Documents, that result from claims against the Administrative Agent in its individual capacity not related to the administration of such properties or any other transaction under this Mortgage or any document included in the Collateral.

Section 5.5. No Action Except Under Collateral Documents or Instructions.

The Administrative Agent agrees that it will not manage, control, use, sell, operate, store, dispose of or otherwise deal with the Aircraft or other property constituting part of the Collateral or subject to any Lease Assignment except (i) in accordance with the powers granted to, or the authority conferred upon, the Administrative Agent pursuant to the applicable Collateral Documents, or (ii) in accordance with the express terms hereof.

Section 5.6. Capacity of the Administrative Agent.

The Administrative Agent has been appointed under Section 8 of the Term Loan Agreement, and is acting hereunder, as a “secured party” for purposes of Section 9-102 of the New York Uniform Commercial Code, as a representative party of and for the benefit of the Secured Parties. Any property held by the Administrative Agent under this Agreement shall be held in trust for the benefit of the Secured Parties and such other secured parties.

ARTICLE VII
