mortgage, chattel mortgage, deed of trust, conditional sales contract, lease, loan or other
material agreement, instrument or document to which Owner is a party or by which Owner or any of
its properties is bound.

          5.1.4 Approvals

delivered by Owner and, assuming the due authorization, execution and delivery thereof by the other

enforceable against Owner in accordance with the respective terms thereof, except as such
enforceability may be limited by bankruptcy, insolvency, reorganization, receivership, moratorium

equity, whether considered in a proceeding at law or in equity.

          5.1.6 Registration and Recordation

and (e) the affixation of the nameplates referred to in Section 4.02(f) of the Trust Indenture, no

     (b) Owner holds all licenses, permits and franchises from the appropriate Government Entities
necessary to authorize Owner to lawfully engage in air transportation and to carry on scheduled

solicited any offer to acquire any such interest or security from, or has sold any such interest or
security to, any person in violation of the Securities Act.

          5.1.12 Section 1110

the power to “dispose” (as such term is used in the Cape Town Treaty) of the Airframe and each

     Each Pass Through Trustee, Subordination Agent, Indenture Trustee and each Note Holder each

Indenture.

          6.4.4 Extent of Interest of Note Holders

     A Note Holder shall not, as such, have any further interest in, or other right with respect

17

 

     (ii) the Indenture Trustee shall have received an opinion of counsel (subject to
customary exceptions) reasonably satisfactory to the Indenture Trustee addressed to
Indenture Trustee to the effect that:

Indenture on the Owner’s right, title and interest in and to the Aircraft shall
continue as a valid and duly perfected first priority security interest and
International Interest and all filing, recording or other action necessary to
protect the same shall have been accomplished (or, if such opinion cannot be given
at the time of such proposed change in registration because such change in
registration is not yet effective, (1) the opinion shall detail what filing,
recording or other action is necessary and (2) the Indenture Trustee shall have
received a certificate from Owner that all possible preparations to accomplish such
filing, recording and other action shall have been done, and such filing, recording
and other action shall be accomplished and a supplemental opinion to that effect
shall be delivered to the Indenture Trustee on or prior to the effective date of
such change in registration);

     (C) unless Owner or the Permitted Air Carrier shall have agreed to provide
insurance covering the risk of requisition of use of the Aircraft by the government
of such country (so long as the Aircraft is registered under the laws of such
country), the laws of such country require fair compensation by the government of
such country payable in currency freely convertible into Dollars and freely
removable from such country (without license or permit, unless Owner prior to such
proposed reregistration has obtained such license or permit) for the taking or
requisition by such government of such use; and

     (D) it is not necessary, solely as a consequence of such change in registration
and without giving effect to any other activity of the Indenture Trustee (or any
Affiliate of the Indenture Trustee), for the Indenture Trustee to qualify to do
business in such jurisdiction as a result of such reregistration in order to
exercise any rights or remedies with respect to the Aircraft.

     (b) In addition, as a condition precedent to any change in registration Owner shall have given
to Indenture Trustee assurances reasonably satisfactory to Indenture Trustee:

	 	     (i)	 	to the effect that the provisions of Section 4.06 of the Trust
Indenture have been complied with after giving effect to such change of
registration;
	 
	 	     (ii)	 	of the payment by Owner of all reasonable out-of-pocket
expenses of each Note Holder and Indenture Trustee in connection with such
change of registry, including, without limitation (1) the reasonable fees and
disbursements of counsel to Indenture Trustee, (2) any filing or recording

PARTICIPATION AGREEMENT (2010-1)

18

 

	 	 	 	fees, Taxes or similar payments incurred in connection with the change of
registration of the Aircraft and the creation and perfection of the
security interest therein in favor of Indenture Trustee for the benefit of

each person named as an indemnitee under any other Operative Agreement afford
each such person substantially the same protection as provided prior to such
change of registration (or Owner shall have agreed upon additional indemnities
that, together with such original indemnities, in the reasonable judgment of
Indenture Trustee, afford such protection).

          6.4.6 Interest in Certain Engines

     Each Note Holder and Indenture Trustee agree, for the benefit of each of the lessor,
conditional seller, mortgagee or secured party of any airframe or engine leased to, or purchased
by, Owner or any Permitted Lessee subject to a lease, conditional sale, trust indenture or other
security agreement that it will not acquire or claim, as against such lessor, conditional seller,
mortgagee or secured party, any right, title or interest in any engine as the result of such engine
being installed on the Airframe at any time while such engine is subject to such lease, conditional
sale, trust indenture or other security agreement and owned by such lessor or conditional seller or
subject to a trust indenture or security interest in favor of such mortgagee or secured party.

permitted assignee of any of the foregoing.

          8.1.3 Separate Agreement

     This Agreement constitutes a separate agreement with respect to each Indemnitee and is
enforceable directly by each such Indemnitee.

PARTICIPATION AGREEMENT (2010-1)

22

 

          8.1.4 Notice

     If a claim for any Expense that an Indemnitee shall be indemnified against under this Section
8.1 is made, such Indemnitee shall give prompt written notice thereof to Owner. Notwithstanding
the foregoing, the failure of any Indemnitee to notify Owner as provided in this Section 8.1.4, or
in Section 8.1.5, shall not release Owner from any of its obligations to indemnify such Indemnitee
hereunder, except to the extent that such failure results in an additional Expense to Owner (in
which event Owner shall not be responsible for such additional expense) or materially impairs
Owner’s ability to contest such claim.

          8.1.5 Notice of Proceedings; Defense of Claims; Limitations

     (a) In case any action, suit or proceeding shall be brought against any Indemnitee for which
Owner is responsible under this Section 8.1, such Indemnitee shall notify Owner of the commencement
thereof and Owner may, at its expense, participate in and to the extent that it shall wish (subject
to the provisions of the following paragraph), assume and control the defense thereof and, subject
to Section 8.1.5(c), settle or compromise the same.

     (b) Owner or its insurer(s) shall have the right, at its or their expense, to investigate or,
if Owner or its insurer(s) shall agree not to dispute liability to the Indemnitee giving notice of
such action, suit or proceeding under this Section 8.1.5 for indemnification hereunder or under any
insurance policies pursuant to which coverage is sought, control the defense of, any action, suit
or proceeding, relating to any Expense for which indemnification is sought pursuant to this Section
8.1, and each Indemnitee shall cooperate with Owner or its insurer(s) with respect thereto;
provided, that Owner shall not be entitled to control the defense of any such action, suit,
proceeding or compromise any such Expense during the continuance of any Event of Default. In
connection with any such action, suit or proceeding being controlled by Owner, such Indemnitee
shall have the right to participate therein, at its sole cost and expense, with counsel reasonably
satisfactory to Owner; provided, that such Indemnitee’s participation does not, in the
reasonable opinion of the independent counsel appointed by the Owner or its insurers to conduct
such proceedings, interfere with the defense of such case.

     (c) In no event shall any Indemnitee enter into a settlement or other compromise with respect
to any Expense without the prior written consent of Owner, which consent shall not be unreasonably
withheld or delayed, unless such Indemnitee waives its right to be indemnified with respect to such
Expense under this Section 8.1.

     (d) In the case of any Expense indemnified by the Owner hereunder which is covered by a policy
of insurance maintained by Owner pursuant to Section 4.06 of the Indenture, at Owner’s expense,
each Indemnitee agrees to cooperate with the insurers in the exercise of their rights to
investigate, defend or compromise such Expense as may be required to retain the benefits of such
insurance with respect to such Expense.

     (e) If an Indemnitee is not a party to this Agreement, Owner may require such Indemnitee to
agree in writing to the terms of this Section 8 and Section 12.8 prior to making any payment to
such Indemnitee under this Section 8.

PARTICIPATION AGREEMENT (2010-1)

23

 

     (f) Nothing contained in this Section 8.1.5 shall be deemed to require an Indemnitee to
contest any Expense or to assume responsibility for or control of any judicial proceeding with
respect thereto.

          8.1.6 Information

     Owner will provide the relevant Indemnitee with such information not within the control of
such Indemnitee, as is in Owner’s control or is reasonably available to Owner, which such
Indemnitee may reasonably request and will otherwise cooperate with such Indemnitee so as to enable
such Indemnitee to fulfill its obligations under Section 8.1.5. The Indemnitee shall supply Owner
with such information not within the control of Owner, as is in such Indemnitee’s control or is
reasonably available to such Indemnitee, which Owner may reasonably request to control or
participate in any proceeding to the extent permitted by Section 8.1.5.

          8.1.7 Effect of Other Indemnities; Subrogation; Further Assurances

     Upon the payment in full by Owner of any indemnity provided for under this Agreement, Owner,
without any further action and to the full extent permitted by Law, will be subrogated to all
rights and remedies of the person indemnified (other than in connection with any indemnity claim
such Indemnitee may have under Section 6.03 or 8.01 of the Trust Indenture) in respect of the
matter as to which such indemnity was paid. Each Indemnitee will give such further assurances or
agreements and cooperate with Owner to permit Owner to pursue such claims, if any, to the extent
reasonably requested by Owner and at Owner’s expense.

          8.1.8 Refunds

     If an Indemnitee receives any refund, in whole or in part, with respect to any Expense paid by
Owner hereunder, it will promptly pay the amount refunded (but not an amount in excess of the
amount Owner or any of its insurers has paid in respect of such Expense) over to Owner unless an
Event of Default shall have occurred and be continuing, in which case such amounts shall be paid
over to Indenture Trustee to hold as security for Owner’s obligations under the Operative
Agreements or, if requested by Owner, applied to satisfy such obligations.

     8.2 Expenses

          8.2.1 Invoices and Payment

     The Indenture Trustee, the Applicable Pass Through Trustees and the Subordination Agent shall
promptly submit to Owner for its prompt approval (which shall not be unreasonably withheld) copies
of invoices in reasonable detail of the Transaction Expenses for which it is responsible for
providing information as they are received (but in no event later than the 90th day after the
Closing Date). If so submitted and approved, the Owner agrees promptly, but in any event no later
than the 105th day after the Closing Date, to pay Transaction Expenses.

PARTICIPATION AGREEMENT (2010-1)

24

 

          8.2.2 Payment of Other Expenses

     Owner shall pay (i) the ongoing fees and expenses of Indenture Trustee, and (ii) all
reasonable out-of-pocket costs and expenses (including the reasonable fees and disbursements of
counsel) incurred by Indenture Trustee or any Note Holder attributable to any waiver, amendment or
modification of any Operative Agreement to the extent requested by Owner.

     8.3 General Tax Indemnity

          8.3.1 General

     Except as provided in Section 8.3.2, Owner agrees that each payment paid by Owner under the
Equipment Notes, and any other payment or indemnity paid by Owner to a Tax Indemnitee under any
Operative Agreement, shall be free of all withholdings or deductions with respect to Taxes of any
nature (other than U.S. federal, state or local withholding taxes on, based on or measured by gross
or net income), and in the event that Owner shall be required by applicable law to make any such
withholding or deduction for any such payment (x) Owner shall make all such withholdings or
deductions, (y) the amount payable by Owner shall be increased so that after making all required
withholdings or deductions such Tax Indemnitee receives the same amount that it would have received
had no such withholdings or deductions been made, and (z) Owner shall pay the full amount withheld
or deducted to the relevant Taxing Authority in accordance with applicable law. Except as provided
in Section 8.3.2 and whether or not any of the transactions contemplated hereby are consummated,
Owner shall pay, indemnify, protect, defend and hold each Tax Indemnitee harmless from all Taxes
imposed by any Taxing Authority that may from time to time be imposed on or asserted against any
Tax Indemnitee or the Aircraft, the Airframe, any Engine or any Part or any interest in any of the
foregoing (whether or not indemnified against by any other Person), upon or with respect to the
Operative Agreements or the transactions or payments contemplated thereby, including but not
limited to any Tax imposed upon or with respect to (x) the Aircraft, the Airframe, any Engine, any
Part, any Operative Agreement (including without limitation any Equipment Notes) or any data or any
other thing delivered or to be delivered under an Operative Agreement, (y) the purchase,
manufacture, acceptance, rejection, sale, transfer of title, return, ownership, mortgaging,
delivery, transport, charter, rental, lease, re-lease, sublease, assignment, possession,
repossession, presence, use, condition, storage, preparation, maintenance, modification,
alteration, improvement, operation, registration, transfer or change of registration,
reregistration, repair, replacement, overhaul, location, control, the imposition of any Lien,
financing, refinancing requested by the Owner, abandonment or other disposition of the Aircraft,
the Airframe, any Engine, any Part, any data or any other thing delivered or to be delivered under
an Operative Agreement or (z) interest, fees or any other income, proceeds, receipts or earnings,
whether actual or deemed, arising upon, in connection with, or in respect of, any of the Operative
Agreements (including the property or income or other proceeds with respect to property held as
part of the Collateral) or the transactions contemplated thereby.

          8.3.2 Certain Exceptions

     The provisions of Section 8.3.1 shall not apply to, and Owner shall have no liability
hereunder for, Taxes:

or (B) any Taxes imposed by any Taxing Authority (other than a Taxing Authority within whose
jurisdiction such Tax Indemnitee is incorporated or organized or maintains its principal place of

jurisdiction but for (I) the location, use or operation of the Aircraft, the Airframe, any Engine
or any Part thereof by an Owner Person within the jurisdiction of the Taxing Authority imposing
such Tax, or (II) the activities of any Owner Person in such jurisdiction, including, but not
limited to, use of any other aircraft by Owner in such jurisdiction, (III) the status of any Owner

conducting activities in such jurisdiction);

     (c) on, or with respect to, or measured by, any trustee fees, commissions or compensation
received by the Pass Through Trustee, Subordination Agent or Indenture Trustee;

fulfill its obligations, if any, under Section 8.3.6 with respect to such return;

     (i) resulting from, or that would not have been imposed but for, any Liens arising as a result
of claims against, or acts or omissions of, or otherwise attributable to such Tax Indemnitee or a

     (j) imposed on any Tax Indemnitee as a result of the breach by such Tax Indemnitee or a

or any Affiliate thereof in any Operative Agreement;

     (k) in the nature of an intangible or similar Tax (i) upon or with respect to the value or
principal amount of the interest of any Note Holder in any Equipment Note or the loan evidenced
thereby but only if such Taxes are in the nature of franchise Taxes or result from the Tax
Indemnitee doing business in the taxing jurisdiction and are imposed because of the place of
incorporation or the activities unrelated to the transactions contemplated by the Operative
Agreements in the taxing jurisdiction of such Tax Indemnitee;

     (l) imposed on a Tax Indemnitee by a Taxing Authority of a jurisdiction outside the United

Tax Indemnitee or a related Tax Indemnitee and such jurisdiction imposing such Tax unrelated to the
transactions contemplated by the Operative Agreements; or

     (m) Taxes relating to ERISA or Section 4975 of the Code.

     For purposes hereof, a Tax Indemnitee and any other Tax Indemnitees that are successors,
assigns, agents, servants or Affiliates of such Tax Indemnitee shall be related Tax Indemnitees.

          8.3.3 Payment

     (a) Owner’s indemnity obligation to a Tax Indemnitee under this Section 8.3 shall equal the
amount which, after taking into account any Tax imposed upon the receipt or accrual of the amounts
payable under this Section 8.3 and any tax benefits actually recognized by such Tax Indemnitee as a
result of the indemnifiable Tax (including, without limitation, any benefits recognized as a result
of an indemnifiable Tax being utilized by such Tax Indemnitee as a credit

PARTICIPATION AGREEMENT (2010-1)

27

 

against Taxes not indemnifiable under this Section 8.3), shall equal the amount of the Tax
indemnifiable under this Section 8.3.

     (b) At Owner’s request, the computation of the amount of any indemnity payment owed by Owner
or any amount owed by a Tax Indemnitee to Owner pursuant to this Section 8.3 shall be verified and
certified by an independent public accounting firm selected by such Tax Indemnitee and reasonably
satisfactory to Owner. Such verification shall be binding. The costs of such verification
(including the fee of such public accounting firm) shall be borne by Owner unless such verification
shall result in an adjustment in Owner’s favor of 5% or more of the net present value of the
payment as computed by such Tax Indemnitee, in which case the costs shall be paid by such Tax
Indemnitee.

     (c) Each Tax Indemnitee shall provide Owner with such certifications, information and
documentation as shall be in such Tax Indemnitee’s possession and as shall be reasonably requested
by Owner to minimize any indemnity payment pursuant to this Section 8.3; provided, that
notwithstanding anything to the contrary contained herein, no Tax Indemnitee shall be required to
provide Owner with any Tax returns.

     (d) Each Tax Indemnitee shall promptly forward to Owner any written notice, bill or advice
received by it from any Taxing Authority concerning any Tax for which it seeks indemnification
under this Section 8.3. Owner shall pay any amount for which it is liable pursuant to this Section
8.3 directly to the appropriate Taxing Authority if legally permissible or upon demand of a Tax
Indemnitee, to such Tax Indemnitee within 30 days of such demand (or, if a contest occurs in
accordance with Section 8.3.4, within 30 days after a Final Determination (as defined below)), but
in no event more than one Business Day prior to the date the Tax to which such amount payable
hereunder relates is due. If requested by a Tax Indemnitee in writing, Owner shall furnish to the
appropriate Tax Indemnitee the original or a certified copy of a receipt for Owner’s payment of any
Tax paid by Owner or such other evidence of payment of such Tax as is acceptable to such Tax
Indemnitee. Owner shall also furnish promptly upon written request such data as any Tax Indemnitee
may reasonably require to enable such Tax Indemnitee to comply with the requirements of any taxing
jurisdiction unless such data is not reasonably available to Owner or, unless such data is
specifically requested by a Taxing Authority, is not customarily furnished by domestic air carriers
under similar circumstances. For purposes of this Section 8.3, a “Final Determination” shall mean
(i) a decision, judgment, decree or other order by any court of competent jurisdiction that occurs
pursuant to the provisions of Section 8.3.4, which decision, judgment, decree or other order has
become final and unappealable, (ii) a closing agreement or settlement agreement entered into in
accordance with Section 8.3.4 that has become binding and is not subject to further review or
appeal (absent fraud, misrepresentation, etc.), or (iii) the termination of administrative
proceedings and the expiration of the time for instituting a claim in a court proceeding.

     (e) If any Tax Indemnitee shall actually realize a tax savings by reason of any Tax paid or
indemnified by Owner pursuant to this Section 8.3 (whether such tax savings shall be by means of a
foreign tax credit, depreciation or cost recovery deduction or otherwise) and such savings is not
otherwise taken into account in computing such payment or indemnity such Tax Indemnitee shall pay
to Owner an amount equal to the lesser of (i) the amount of such tax savings, plus any additional
tax savings recognized as the result of any payment made pursuant

PARTICIPATION AGREEMENT (2010-1)

28

 

to this sentence, when, as, if, and to the extent, realized or (ii) the amount of all payments
pursuant to this Section 8.3 by Owner to such Tax Indemnitee (less any payments previously made by
such Tax Indemnitee to Owner pursuant to this Section 8.3.3 (e)) (and the excess, if any, of the
amount described in clause (i) over the amount described in clause (ii) shall be carried forward
and applied to reduce pro tanto any subsequent obligations of Owner to make payments to such Tax
Indemnitee pursuant to this Section 8.3); provided, that such Tax Indemnitee shall not be required
to make any payment pursuant to this sentence so long as a Lease Event of Default of a monetary
nature has occurred and is continuing. If a tax benefit is later disallowed or denied, the
disallowance or denial shall be treated as a Tax indemnifiable under Section 8.3.1 without regard
to the provisions of Section 8.3.2 (other than Section 8.3.2 (f)). Each such Tax Indemnitee shall
in good faith use reasonable efforts in filing its tax returns and in dealing with Taxing
Authorities to seek and claim any such tax benefit.

          8.3.4 Contest

     (a) If a written claim is made against a Tax Indemnitee for Taxes with respect to which Owner
could be liable for payment or indemnity hereunder, or if a Tax Indemnitee makes a determination
that a Tax is due for which Owner could have an indemnity obligation hereunder, such Tax Indemnitee
shall promptly give Owner notice in writing of such claim (provided, that failure to so notify
Owner shall not relieve Owner of its indemnity obligations hereunder unless such failure to notify
effectively forecloses Owner’s rights to require a contest of such claim) and shall take no action
with respect to such claim without the prior written consent of Owner for 30 days following the
receipt of such notice by Owner; provided, that, in the case of a claim made against a Tax
Indemnitee, if such Tax Indemnitee shall be required by law to take action prior to the end of such
30-day period, such Tax Indemnitee shall, in such notice to Owner, so inform Owner, and such Tax
Indemnitee shall take no action for as long as it is legally able to do so (it being understood
that a Tax Indemnitee shall be entitled to pay the Tax claimed and sue for a refund prior to the
end of such 30-day period if (i)(A) the failure to so pay the Tax would result in substantial
penalties (unless immediately reimbursed by Owner) and the act of paying the Tax would not
materially prejudice the right to contest or (B) the failure to so pay would result in criminal
penalties and (ii) such Tax Indemnitee shall take any action so required in connection with so
paying the Tax in a manner that is the least prejudicial to the pursuit of the contest). In
addition, such Tax Indemnitee shall (provided, that Owner shall have agreed to keep such
information confidential other than to the extent necessary in order to contest the claim) furnish
Owner with copies of any requests for information from any Taxing Authority relating to such Taxes
with respect to which Owner may be required to indemnify hereunder. If requested by Owner in
writing within 30 days after its receipt of such notice, such Tax Indemnitee shall, at the expense
of Owner (including, without limitation, all reasonable costs, expenses and reasonable attorneys’
and accountants’ fees and disbursements), in good faith contest (or, if permitted by applicable
law, allow Owner to contest) through appropriate administrative and judicial proceedings the
validity, applicability or amount of such Taxes by (I) resisting payment thereof, (II) not paying
the same except under protest if protest is necessary and proper or (III) if the payment is made,
using reasonable efforts to obtain a refund thereof in an appropriate administrative and/or
judicial proceeding. If requested to do so by Owner, the Tax Indemnitee shall appeal any adverse
administrative or judicial decision, except that the Tax Indemnitee shall not be required to pursue
any appeals to the United States Supreme Court. If and to the extent the Tax Indemnitee is able to
separate the contested issue or issues from other

PARTICIPATION AGREEMENT (2010-1)

29

 

issues arising in the same administrative or judicial proceeding that are unrelated to the
transactions contemplated by the Operative Agreements without, in the good faith judgment of such
Tax Indemnitee, adversely affecting such Tax Indemnitee, such Tax Indemnitee shall permit Owner to
control the conduct of any such proceeding and shall provide to Owner (at Owner’s cost and expense)
with such information or data that is in such Tax Indemnitee’s control or possession that is
reasonably necessary to conduct such contest. In the case of a contest controlled by a Tax
Indemnitee, such Tax Indemnitee shall consult with Owner in good faith regarding the manner of
contesting such claim and shall keep Owner reasonably informed regarding the progress of such
contest. A Tax Indemnitee shall not fail to take any action expressly required by this Section
8.3.4 (including, without limitation, any action regarding any appeal of an adverse determination
with respect to any claim) or settle or compromise any claim without the prior written consent of
the Owner (except as contemplated by Section 8.3.4(b) or (c)).

     (b) Notwithstanding the foregoing, in no event shall a Tax Indemnitee be required to pursue
any contest (or to permit Owner to pursue any contest) unless (i) Owner shall have agreed to pay
such Tax Indemnitee on demand all reasonable costs and expenses incurred by such Tax Indemnitee in
connection with contesting such Taxes, including, without limitation, all reasonable out of pocket
costs and expenses and reasonable attorneys’ and accountants’ fees and disbursements, (ii) if such
contest shall involve the payment of the claim, Owner shall advance the amount thereof (to the
extent indemnified hereunder) plus interest, penalties and additions to tax with respect thereto
that are required to be paid prior to the commencement of such contest on an interest-free
after-Tax basis to such Tax Indemnitee (and such Tax Indemnitee shall promptly pay to the Owner any
net realized tax benefits resulting from such advance including any tax benefits resulting from
making such payment), (iii) such Tax Indemnitee shall have reasonably determined that the action to
be taken will not result in any material risk of forfeiture, sale or loss of the Aircraft (unless
Owner shall have made provisions to protect the interests of any such Tax Indemnitee in a manner
reasonably satisfactory to such Tax Indemnitee) (provided, that such Tax Indemnitee agrees to
notify Owner in writing promptly after it becomes aware of any such risk), (iv) no Lease Event of
Default shall have occurred and be continuing unless Owner has provided security for its
obligations hereunder by advancing to such Tax Indemnitee before proceeding or continuing with such
contest, the amount of the Tax being contested, plus any interest and penalties and an amount
estimated in good faith by such Tax Indemnitee for expenses, and (v) prior to commencing any
judicial action controlled by Owner, Owner shall have acknowledged its liability for such claim
hereunder, provided that Owner shall not be bound by its acknowledgment if the Final Determination
articulates conclusions of law and fact that demonstrate that Owner has no liability for the
contested amounts hereunder. Notwithstanding the foregoing, if any Tax Indemnitee shall release,
waive, compromise or settle any claim which may be indemnifiable by Owner pursuant to this Section
8.3 without the written permission of Owner, Owner’s obligation to indemnify such Tax Indemnitee
with respect to such claim (and all directly related claims and claims based on the outcome of such
claim) shall terminate, subject to Section 8.3.4(c), and subject to Section 8.3.4(c), such Tax
Indemnitee shall repay to Owner any amount previously paid or advanced to such Tax Indemnitee with
respect to such claim, plus interest at the rate that would have been payable by the relevant
Taxing Authority with respect to a refund of such Tax.

PARTICIPATION AGREEMENT (2010-1)

30

 

     (c) Notwithstanding anything contained in this Section 8.3, a Tax Indemnitee will not be
required to contest the imposition of any Tax and shall be permitted to settle or compromise any
claim without Owner’s consent if such Tax Indemnitee (i) shall waive its right to indemnity under
this Section 8.3 with respect to such Tax (and any directly related claim and any claim the outcome
of which is determined based upon the outcome of such claim), (ii) shall pay to Owner any amount
previously paid or advanced by Owner pursuant to this Section 8.3 with respect to such Tax, plus
interest at the rate that would have been payable by the relevant Taxing Authority with respect to
a refund of such Tax, and (iii) shall agree to discuss with Owner the views or positions of any
relevant Taxing Authority with respect to the imposition of such Tax.

          8.3.5 Refund

     If any Tax Indemnitee shall receive a refund of, or be entitled to a credit against other
liability for, all or any part of any Taxes paid, reimbursed or advanced by Owner, such Tax
Indemnitee shall pay to Owner within 30 days of such receipt an amount equal to the lesser of (a)
the amount of such refund or credit plus any net tax benefit (taking into account any Taxes
incurred by such Tax Indemnitee by reason of the receipt of such refund or realization of such
credit) actually realized by such Tax Indemnitee as a result of any payment by such Tax Indemnitee
made pursuant to this sentence (including this clause (a)) and (b) such tax payment, reimbursement
or advance by Owner to such Tax Indemnitee theretofore made pursuant to this Section 8.3 (and the
excess, if any, of the amount described in clause (a) over the amount described in clause (b) shall
be carried forward and applied to reduce pro tanto any subsequent obligation of Owner to make
payments to such Tax Indemnitee pursuant to this Section 8.3). If, in addition to such refund or
credit, such Tax Indemnitee shall receive (or be credited with) an amount representing interest on
the amount of such refund or credit, such Tax Indemnitee shall pay to Owner within 30 days of such
receipt or realization of such credit that proportion of such interest that shall be fairly
attributable to Taxes paid, reimbursed or advanced by Owner prior to the receipt of such refund or
realization of such credit.

          8.3.6 Tax Filing

     If any report, return or statement is required to be filed with respect to any Tax which is
subject to indemnification under this Section 8.3, Owner shall timely file the same (except for any
such report, return or statement which a Tax Indemnitee has timely notified the Owner in writing
that such Tax Indemnitee intends to file, or for which such Tax Indemnitee is required by law to
file, in its own name); provided, that the relevant Tax Indemnitee shall furnish Owner with any
information in such Tax Indemnitee’s possession or control that is reasonably necessary to file any
such return, report or statement and is reasonably requested in writing by Owner (it being
understood that the Tax Indemnitee shall not be required to furnish copies of its actual tax
returns, although it may be required to furnish relevant information contained therein). Owner
shall either file such report, return or statement and send a copy of such report, return or
statement to such Tax Indemnitee, or, where Owner is not permitted to file such report, return or
statement, it shall notify such Tax Indemnitee of such requirement and prepare and deliver such
report, return or statement to such Tax Indemnitee in a manner satisfactory to such Tax Indemnitee
within a reasonable time prior to the time such report, return or statement is to be filed.

PARTICIPATION AGREEMENT (2010-1)

31

 

          8.3.7 Forms

     Each Tax Indemnitee agrees to furnish from time to time to Owner or Indenture Trustee or to
such other person as Owner or Indenture Trustee may designate, at Owner’s or Indenture Trustee’s
request, such duly executed and properly completed forms as may be necessary or appropriate in
order to claim any reduction of or exemption from any withholding or other Tax imposed by any
Taxing Authority, if (x) such reduction or exemption is available to such Tax Indemnitee and (y)
Owner has provided such Tax Indemnitee with any information necessary to complete such form not
otherwise reasonably available to such Tax Indemnitee.

          8.3.8 Non-Parties

     If a Tax Indemnitee is not a party to this Agreement, Owner may require the Tax Indemnitee to
agree in writing, in a form reasonably acceptable to Owner, to the terms of this Section 8.3 and
Section 15.8 prior to making any payment to such Tax Indemnitee under this Section 8.3.

          8.3.9 Subrogation

     Upon payment of any Tax by Owner pursuant to this Section 8.3 to or on behalf of a Tax
Indemnitee, Owner, without any further action, shall be subrogated to any claims that such Tax
Indemnitee may have relating thereto. Such Tax Indemnitee shall cooperate with Owner (to the
extent such cooperation does not result in any unreimbursed cost, expense or liability to such Tax
Indemnitee) to permit Owner to pursue such claims.

     8.4 Payments

     Any payments made pursuant to Section 8.1 or 8.3 shall be due on the 60th day after demand
therefor and shall be made directly to the relevant Indemnitee or Tax Indemnitee or to Owner, in
immediately available funds at such bank or to such account as specified by such Indemnitee or Tax
Indemnitee or Owner, as the case may be, in written directives to the payor, or, if no such
direction shall have been given, by check of the payor payable to the order of, and mailed to, such
Indemnitee or Tax Indemnitee or Owner, as the case may be, by certified mail, postage prepaid, at
its address as set forth in this Agreement.

          8.5 Interest

     If any amount, payable by Owner, any Indemnitee or any Tax Indemnitee under Section 8.1 or 8.3
is not paid when due, the person obligated to make such payment shall pay on demand, to the extent
permitted by Law, to the person entitled thereto, interest on any such amount for the period from
and including the due date for such amount to but excluding the date the same is paid, at the
Payment Due Rate. Such interest shall be paid in the same manner as the unpaid amount in respect
of which such interest is due.

          8.6 Benefit of Indemnities

     The obligations of Owner in respect of all indemnities, obligations, adjustments and payments
in Section 8.1 or 8.3 are expressly made for the benefit of, and shall be enforceable by,

PARTICIPATION AGREEMENT (2010-1)

32

 

the Indemnitee or Tax Indemnitee entitled thereto, notwithstanding any provision of the Trust
Indenture.

SECTION 9. ASSIGNMENT OR TRANSFER OF INTEREST

     9.1 Note Holders

     Subject to Section 6.3.2 hereof and Section 2.06 of the Trust Indenture, any Note Holder may,
at any time and from time to time, Transfer or grant participations in all or any portion of the
Equipment Notes and/or all or any portion of its beneficial interest in its Equipment Notes to any
person (it being understood that the sale or issuance of Pass Through Certificates by a Pass
Through Trustee shall not be considered a Transfer or participation); provided, that any
participant in any such participations shall not have any direct rights under the Operative
Agreements or any Lien on all or any part of the Aircraft or the Collateral and Owner shall not
have any increased liability or obligations as a result of any such participation. In the case of
any such Transfer, the Transferee, by acceptance of Equipment Notes in connection with such
Transfer, shall be deemed to be bound by (i) all of the covenants of Note Holders contained in the
Operative Agreements and (ii) certain terms of the Intercreditor Agreement as specified in such
Equipment Notes and/or Section 2.06 of the Trust Indenture.

          9.2 Effect of Transfer

     Upon any Transfer in accordance with Section 9.1 (other than any Transfer by any Note Holder,
to the extent it only grants participations in Equipment Notes or in its beneficial interest
therein), Transferee shall be deemed a “Note Holder,” for all purposes of this Agreement and the
other Operative Agreements, and the transferring Note Holder shall be released from all of its
liabilities and obligations under this Agreement and any other Operative Agreements to the extent
such liabilities and obligations arise after such Transfer and, in each case, to the extent such
liabilities and obligations are assumed by the Transferee; provided, that such transferring
Note Holder (and its respective Affiliates, successors, assigns, agents, servants, representatives,
directors and officers) will continue to have the benefit of any rights or indemnities under any
Operative Agreement vested or relating to circumstances, conditions, acts or events prior to such
Transfer.

SECTION 10. SECTION 1110

     It is the intention of each of the Owner, the Note Holders (such intention being evidenced by
each of their acceptance of an Equipment Note), and Indenture Trustee that Indenture Trustee shall
be entitled to the benefits of Section 1110 in the event of a case under Chapter 11 of the
Bankruptcy Code in which Owner is a debtor.

SECTION 11. CHANGE OF CITIZENSHIP

     11.1 Generally

     Without prejudice to the representations, warranties or covenants regarding the status of any
party hereto as a Citizen of the United States, each of Owner, WTC and Indenture Trustee agrees
that it will, immediately upon obtaining knowledge of any facts that would cast doubt

PARTICIPATION AGREEMENT (2010-1)

33

 

upon its continuing status as a Citizen of the United States and promptly upon public
disclosure of negotiations in respect of any transaction which would or might adversely affect such
status, notify in writing all parties hereto of all relevant matters in connection therewith.

     11.2 Indenture Trustee

     Upon WTC giving any notice in accordance with Section 11.1, Indenture Trustee shall (if and so
long as such citizenship is necessary under the Act as in effect at such time or, if it is not
necessary, if and so long as Indenture Trustee’s citizenship could have any adverse effect on
Owner, or any Note Holder), subject to Section 9.02 of the Trust Indenture, resign as Indenture
Trustee promptly upon its ceasing to be such a citizen.

SECTION 12. MISCELLANEOUS

     12.1 Amendments

     No provision of this Agreement may be amended, supplemented, waived, modified, discharged,
terminated or otherwise varied orally, but only by an instrument in writing that specifically
identifies the provision of this Agreement that it purports to amend, supplement, waive, modify,
discharge, terminate or otherwise vary and is signed by the party against which the enforcement of
the amendment, supplement, waiver, modification, discharge, termination or variance is sought.
Each such amendment, supplement, waiver, modification, discharge, termination or variance shall be
effective only in the specific instance and for the specific purpose for which it is given. No
provision of this Agreement shall be varied or contradicted by oral communication, course of
dealing or performance or other manner not set forth in an agreement, document or instrument in
writing and signed by the party against which enforcement of the same is sought.

     12.2 Severability

     If any provision hereof shall be held invalid, illegal or unenforceable in any respect in any
jurisdiction, then, to the extent permitted by Law, (a) all other provisions hereof shall remain in
full force and effect in such jurisdiction and (b) such invalidity, illegality or unenforceability
shall not affect the validity, legality or enforceability of such provision in any other
jurisdiction. If, however, any Law pursuant to which such provisions are held invalid, illegal or
unenforceable may be waived, such Law is hereby waived by the parties hereto to the full extent
permitted, to the end that this Agreement shall be deemed to be a valid and binding agreement in
all respects, enforceable in accordance with its terms.

     12.3 Survival

     The indemnities set forth herein shall survive the delivery or return of the Aircraft, the
Transfer of any interest by any Note Holder of its Equipment Note and the expiration or other
termination of this Agreement or any other Operative Agreement.

that may hereafter be executed and (b) financial statements, certificates and other information
previously or hereafter furnished to any party hereto, may be reproduced by such party by any
photographic, photostatic, microfilm, micro-card, miniature photographic or other similar process,

the regular course of business) and any enlargement, facsimile or further reproduction of such
reproduction likewise is admissible in evidence.

     12.5 Counterparts

exercising, any of its respective rights, powers, remedies or privileges under this Agreement or
provided at Law, in equity or otherwise shall impair, prejudice or constitute a waiver of any such
right, power, remedy or privilege or be construed as a waiver of any breach hereof or default
hereunder or as an acquiescence therein nor shall any single or partial exercise of any such right,
power, remedy or privilege preclude any other or further exercise thereof by it or the exercise of
any other right, power, remedy or privilege by it. No notice to or demand on any party hereto in
any case shall, unless otherwise required under this Agreement, entitle such party to any other or
further notice or demand in similar or other circumstances or constitute a waiver of the rights of
any party hereto to any other or further action in any circumstances without notice or demand.

     12.7 Notices

2

 

          (4) All rents, revenues and other proceeds collected by the Indenture Trustee pursuant to

waive any of the warranties or indemnities contained therein, except in the exercise of the Owner’s
reasonable business judgment) and to retain any recovery or benefit resulting from the enforcement
of any warranty or indemnity under the Indenture Agreements; and provided further that,
notwithstanding the occurrence or continuation of an Event of Default, the Indenture Trustee shall
not enter into any amendment of any Indenture Agreement which would increase the obligations of the
Owner thereunder.

          TO HAVE AND TO HOLD all and singular the aforesaid property unto the Indenture Trustee, and
its successors and assigns, in trust for the equal and proportionate benefit and security of the
Note Holders and the Indenture Indemnitees, except as provided in Section 2.12 and Article III

negotiation, date of maturity thereof or otherwise for any reason whatsoever, and for the uses and
purposes and in all cases and as to all property specified in clauses (1) through (5) inclusive
above, subject to the terms and provisions set forth in this Trust Indenture.

          It is expressly agreed that anything herein contained to the contrary notwithstanding, the
Owner shall remain liable under the Indenture Agreements to perform all of the obligations assumed
by it thereunder, except to the extent prohibited or excluded from doing so pursuant to the terms
and provisions thereof, and the Indenture Trustee, the Note Holders and the Indenture Indemnitees
shall have no obligation or liability under the Indenture Agreements by reason of or arising out of
the assignment hereunder, nor shall the Indenture Trustee, the Note Holders or the Indenture
Indemnitees be required or obligated in any manner to perform or fulfill any obligations of the
Owner under or pursuant to the Indenture Agreements, 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 which may have been assigned to it or to which it may be entitled at any time or times.

          The Owner does hereby constitute the Indenture Trustee the true and lawful attorney of the
Owner, irrevocably, granted for good and valuable consideration and coupled with an interest and
with full power of substitution, and with full power (in the name of the Owner or otherwise) to ask
for, require, demand, receive, compound and give acquittance for any and all monies and claims for
monies (in each case including insurance and requisition proceeds) due and to become due under or
arising out of the Indenture Agreements, and all other property which 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 proceedings which the
Indenture Trustee may deem to be necessary or advisable in the premises; provided that no
action of the Indenture Trustee pursuant to this paragraph shall increase the obligations or
liabilities of the Owner to any Person beyond those obligations and liabilities specifically set
forth in this Trust Indenture and in the other Operative Agreements and the Indenture Trustee shall
not exercise any such rights except upon the occurrence and during the continuance of an Event of
Default hereunder.

          The Owner agrees that at any time and from time to time, upon the written request of the
Indenture Trustee, the Owner will promptly and duly execute and deliver or cause to be duly
executed and delivered any and all such further instruments and documents (including without
limitation UCC continuation statements) as the Indenture Trustee may reasonably deem necessary to
perfect, preserve or protect the mortgage, security interests, International Interests and
assignments created or intended to be created hereby or to obtain for the Indenture Trustee the
full benefits of the assignment hereunder and of the rights and powers herein granted.

	 	[____________]

          US AIRWAYS, INC., a Delaware corporation (“Owner”), hereby promises to pay to
__________________, or the registered assignee thereof, the principal sum of $____________ (the
“Original Amount”), together with interest on the amount of the Original Amount remaining unpaid
from time to time (calculated on the basis of a year of 360 days comprised of twelve 30-day months)
from the date hereof until paid in full at a rate per annum equal to the Debt Rate. The Original
Amount of this Equipment Note shall be due and payable in installments on the dates set forth in
Schedule I hereto equal to the corresponding percentage of the Original Amount of this Equipment
Note set forth in Schedule I hereto. Accrued but unpaid interest shall be due and payable in
semi-annual installments commencing on April 22, 2011 and thereafter on April 22 and October 22 of
each year, to and including [_______________]. Notwithstanding the foregoing, the final payment
made on this Equipment Note shall be in an amount sufficient to discharge in full the unpaid
Original Amount and all accrued and unpaid interest on, and any other amounts due under, this
Equipment Note. Notwithstanding anything to the contrary contained herein, if any date on which a
payment under this Equipment Note becomes due and payable is not a Business Day, then such payment
shall not be made on such scheduled date but shall be made on the next succeeding Business Day and
if such payment is made on such next succeeding Business Day, no interest shall accrue on the
amount of such payment during such extension.

          For purposes hereof, the term “Trust Indenture” means the Trust Indenture and Security
Agreement [____] dated as of [______ __], 20[__], between the Owner and Wilmington Trust Company
(the “Indenture Trustee”), as the same may be amended or supplemented from time to time. All other
capitalized terms used in this Equipment Note and not defined herein shall have the respective
meanings assigned in the Trust Indenture.

          This Equipment Note shall bear interest, payable on demand, at the Payment Due Rate
(calculated on the basis of a year of 360 days comprised of twelve 30-day months) on any overdue
Original Amount, any overdue Make-Whole Amount, if any, and (to the extent

5

 

permitted by applicable Law) any overdue interest and any other amounts payable hereunder
which are overdue, in each case for the period the same is overdue. Amounts shall be overdue if
not paid when due (whether at stated maturity, by acceleration or otherwise).

          There shall be maintained an Equipment Note Register for the purpose of registering transfers
and exchanges of Equipment Notes at the Corporate Trust Office of the Indenture Trustee or at the
office of any successor in the manner provided in Section 2.06 of the Trust Indenture.

          The Original Amount and interest and other amounts due hereunder shall be payable in Dollars
in immediately available funds at the Corporate Trust Office of the Indenture Trustee, or as
otherwise provided in the Trust Indenture. Each such payment shall be made on the date such
payment is due and without any presentment or surrender of this Equipment Note, except that in the
case of any final payment with respect to this Equipment Note, the Equipment Note shall be
surrendered promptly thereafter to the Indenture Trustee for cancellation.

          The holder hereof, by its acceptance of this Equipment Note, agrees that, except as provided
in the Trust Indenture, each payment of the Original Amount, Make-Whole Amount, if any, and
interest received by it hereunder shall be applied, first, to the payment of Make-Whole
Amount, if any, and any other amount (other than as covered by any of the following clauses) due
hereunder or under the Trust Indenture, second, to the payment of accrued interest on this
Equipment Note (as well as any interest on any overdue Original Amount, any overdue Make-Whole
Amount, if any, or, to the extent permitted by Law, any overdue interest and other amounts
hereunder) to the date of such payment, third, to the payment of the Original Amount of
this Equipment Note then due, and fourth, the balance, if any, remaining thereafter, to the
payment of installments of the Original Amount of this Equipment Note remaining unpaid in the
inverse order of their maturity.

          This Equipment Note is one of the Equipment Notes referred to in the Trust Indenture which
have been or are to be issued by the Owner pursuant to the terms of the Trust Indenture. The
Collateral is held by the Indenture Trustee as security, in part, for the Equipment Notes. The
provisions of this Equipment Note are subject to the Trust Indenture and the Related Indentures.
Reference is hereby made to the Trust Indenture and the Related Indentures for a complete statement
of the rights and obligations of the holder of, and the nature and extent of the security for, this
Equipment Note (including as a “Related Equipment Note” under each of the Related Indentures) and
the rights and obligations of the holders of, and the nature and extent of the security for, any
other Equipment Notes executed and delivered under the Trust Indenture, as well as for a statement
of the terms and conditions of the Trust created by the Trust Indenture, to all of which terms and
conditions in the Trust Indenture each holder hereof agrees by its acceptance of this Equipment
Note.

          As provided in the Trust Indenture and subject to certain limitations therein set forth, this
Equipment Note is exchangeable for a like aggregate Original Amount of Equipment Notes of different
authorized denominations, as requested by the holder surrendering the same.

          Prior to due presentment for registration of transfer of this Equipment Note, the Owner and
the Indenture Trustee shall treat the person in whose name this Equipment Note is registered as the

the Trust Indenture but not otherwise. In addition, this Equipment Note may be accelerated as
provided in Section 5.02 of the Trust Indenture.

4.1(a)(iii) of the Intercreditor Agreement, as further specified in Section 2.06 of the Trust
Indenture, to all of which terms and conditions in the Intercreditor Agreement each holder hereof
agrees by its acceptance of this Equipment Note.

          [The indebtedness evidenced by this Equipment Note is, to the extent and in the manner
provided in the Trust Indenture, subordinate and subject in right of payment to the prior payment
in full of the Secured Obligations (as defined in the Trust Indenture) in respect of [Series A
Equipment Notes and Related Series A Equipment Notes]8 [Series A Equipment Notes, Series

attorney-in-fact for such purpose.]10

          Unless the certificate of authentication hereon has been executed by or on behalf of the
Indenture Trustee by manual signature, this Equipment Note shall not be entitled to any benefit

(as defined in the Note Purchase Agreement), subject to the terms of Section 4(a)(v) of the Note
Purchase Agreement and Section 9.1(d) of the Intercreditor Agreement. If the Owner so elects to
issue the Additional Series Equipment Notes, Additional Series Equipment Notes shall be issued in a
single separate series, shall be dated the date of original issuance thereof and shall have such
maturity, principal amount and interest rate as specified in an amendment to this Trust Indenture.
The Equipment Notes shall be issued in registered form only. The Equipment Notes shall be issued
in denominations of $1,000 and integral multiples thereof, except that one Equipment Note of each
Series may be in an amount that is not an integral multiple of $1,000. Without limitation of the
foregoing, new Series B Equipment Notes may be issued pursuant to the provisions of Section
2.10(b).

          Each Equipment Note shall bear interest at the applicable Debt Rate (calculated on the basis
of a year of 360 days comprised of twelve 30-day months) on the unpaid Original Amount thereof from
time to time outstanding. Accrued interest shall be payable in arrears on April 22, 2011, and on
each April 22 and October 22 thereafter until maturity. The Original Amount of each Equipment Note
shall be payable on the dates and in the installments equal to the corresponding percentage of the
Original Amount as set forth in Schedule I hereto (as amended, in the case of any Additional
Series, at the time of original issuance of such Additional Series) which shall be attached as
Schedule I to such Equipment Notes. Notwithstanding the foregoing, the final payment made under
each Equipment Note shall be in an amount sufficient to discharge in full the unpaid Original
Amount and all accrued and unpaid interest on, and any other amounts due under, such Equipment
Note. Each Equipment Note shall bear interest, payable on demand, at the Payment Due Rate
(calculated on the basis of a year of 360 days comprised of twelve 30-day months) on any part of
the Original Amount, Make-Whole Amount, if any, and, to the extent permitted by applicable Law,
interest and any other amounts payable thereunder not paid when due for any period during which the
same shall be overdue, in each case for the period the same is overdue. Amounts under any
Equipment Note shall be overdue if not paid when due (whether at stated maturity, by acceleration
or otherwise). Notwithstanding anything to the contrary contained herein, if any date on which a
payment under any Equipment Note becomes due and payable is not a Business Day then such payment
shall not be made on such scheduled date but shall be made on the next succeeding Business Day and
if such payment is made on such next succeeding Business Day, no interest shall accrue on the
amount of such payment during such extension.

          The Owner agrees to pay to the Indenture Trustee for distribution in accordance with Section
3.04 hereof: (a)(i) to the extent not payable (whether or not in fact paid) under

10

 

Section 6(a) of the Note Purchase Agreement, an amount equal to the fees payable to the
Liquidity Provider under Section 2.03 of each Liquidity Facility and the related Fee Letter (as
defined in the Intercreditor Agreement) multiplied by a fraction the numerator of which shall be
the then outstanding aggregate principal amount of the Series A Equipment Notes and Series B
Equipment Notes and the denominator of which shall be the then outstanding aggregate principal
amount of all “Series A Equipment Notes” and “Series B Equipment Notes” (each as defined in the
Note Purchase Agreement); (ii) (x) the amount equal to interest on any Downgrade Advance (other
than any Applied Downgrade Advance) payable under Section 3.07 of each Liquidity Facility minus
Investment Earnings from such Downgrade Advance multiplied by (y) the fraction specified in the
foregoing clause (i); (iii) (x) the amount equal to interest on any Non-Extension Advance (other
than any Applied Non-Extension Advance) payable under Section 3.07 of each Liquidity Facility minus
Investment Earnings from such Non-Extension Advance multiplied by (y) the fraction specified in the
foregoing clause (i); (iv) (x) the amount equal to interest on any Special Termination Advance
(other than any Applied Special Termination Advance) payable under Section 3.07 of each Liquidity
Facility minus Investment Earnings from such Special Termination Advance multiplied by (y) the
fraction specified in the foregoing clause (i); (v) if any payment default shall have occurred and
be continuing with respect to interest on any “Series A Equipment Notes” or “Series B Equipment
Notes” (each as defined in the Note Purchase Agreement), (x) the excess, if any, of (1) an amount
equal to interest on any Unpaid Advance, Applied Downgrade Advance, Applied Non-Extension Advance
or Applied Special Termination Advance payable under Section 3.07 of each Liquidity Facility over
(2) the sum of Investment Earnings from any Final Advance plus any amount of interest at the
Payment Due Rate actually payable (whether or not in fact paid) by the Owner on the overdue
scheduled interest on the “Equipment Notes” (as defined in the Note Purchase Agreement) in respect
of which such Unpaid Advance, Applied Downgrade Advance, Applied Non-Extension Advance or Applied
Special Termination Advance was made by the Liquidity Provider multiplied by (y) a fraction the
numerator of which shall be the then aggregate overdue amounts of interest on the Series A
Equipment Notes and Series B Equipment Notes (other than interest becoming due and payable solely
as a result of acceleration of any such Equipment Notes) and the denominator of which shall be the
then aggregate overdue amounts of interest on all “Series A Equipment Notes” and “Series B
Equipment Notes” (each as defined in the Note Purchase Agreement) (other than interest becoming due
and payable solely as a result of acceleration of any such “Equipment Notes”); and (vi) any other
amounts owed to the Liquidity Provider by the Subordination Agent as borrower under each Liquidity
Facility other than amounts due as repayment of advances thereunder or as interest on such
advances, except to the extent payable pursuant to clause (ii), (iii), (iv) or (v) above,
multiplied by the fraction specified in the foregoing clause (i), (b) without duplication of any
amounts paid or payable pursuant to the provisions hereof, Owner’s pro rata share of all
compensation and reimbursement of expenses, disbursements and advances payable by the Owner under
the Pass Through Trust Agreements, (c) without duplication of any amounts paid or payable pursuant
to the provisions hereof, Owner’s pro rata share of all compensation and reimbursement of expenses
and disbursements payable to the Subordination Agent under the Intercreditor Agreement except with
respect to any income or franchise taxes incurred by the Subordination Agent in connection with the
transactions contemplated by the Intercreditor Agreement and (d) in the event the Owner requests
any amendment to any Operative Agreement or Pass Through Agreement, the Owner’s pro rata share of
all reasonable fees and expenses (including, without limitation, fees and

11

 

disbursements of counsel) of the Escrow Agents and the Paying Agents in connection therewith
payable by the Pass Through Trustees under the Escrow Agreements. As used herein, “Owner’s pro
rata share” means as of any time a fraction, the numerator of which is the principal balance then
outstanding of Equipment Notes and the denominator of which is the aggregate principal balance then
outstanding of all “Equipment Notes” (as each such term is defined in each of the Operative
Indentures). For purposes of this paragraph, the terms “Applied Downgrade Advance”, “Applied
Non-Extension Advance”, “Applied Special Termination Advance”, “Cash Collateral Account”,
“Downgrade Advance”, “Final Advance”, “Investment Earnings”, “Non-Extension Advance”, “Special
Termination Advance” and “Unpaid Advance” shall have the meanings specified in each Liquidity
Facility.

          The Equipment Notes shall be executed on behalf of the Owner by one of its authorized
officers. Equipment Notes bearing the signatures of individuals who were at any time the proper
officers of the Owner shall bind the Owner, notwithstanding that such individuals or any of them
have ceased to hold such offices prior to the authentication and delivery of such Equipment Notes
or did not hold such offices at the respective dates of such Equipment Notes. The Owner may from
time to time execute and deliver Equipment Notes with respect to the Aircraft to the Indenture
Trustee for authentication upon original issue and such Equipment Notes shall thereupon be
authenticated and delivered by the Indenture Trustee upon the written request of the Owner signed
by an authorized officer of the Owner. No Equipment Note shall be secured by or entitled to any
benefit under this Trust Indenture or be valid or obligatory for any purposes, unless there appears
on such Equipment Note a certificate of authentication in the form provided for herein executed by
the Indenture Trustee by the manual signature of one of its authorized officers and such
certificate upon any Equipment Notes be conclusive evidence, and the only evidence, that such
Equipment Note has been duly authenticated and delivered hereunder.

          The aggregate Original Amount of any Series of Equipment Notes issued hereunder shall not
exceed the amount set forth as the maximum therefor on Schedule I hereto (as amended, in the case
of any Additional Series, at the time of original issuance of such Additional Series).

          SECTION 2.03. Method of Payment

               (a) The Original Amount of, interest on, Make-Whole Amount, if any, and other amounts due
under each Equipment Note or hereunder will be payable in Dollars by wire transfer of immediately
available funds not later than 12:30 p.m., New York time, on the due date of payment to the
Indenture Trustee at the Corporate Trust Office for distribution among the Note Holders in the
manner provided herein, and payment of such amount by the Owner to the Indenture Trustee shall be
deemed to satisfy the Owner’s obligation to make such payment. The Owner shall not have any
responsibility for the distribution of such payment to any Note Holder. Notwithstanding the
foregoing or any provision in any Equipment Note to the contrary, the Indenture Trustee will use
reasonable efforts to pay or cause to be paid, if so directed in writing by any Note Holder (with a
copy to the Owner), all amounts paid by the Owner hereunder and under such holder’s Equipment Note
or Equipment Notes to such holder or a nominee therefor (including all amounts distributed pursuant
to Article III of this Trust

12

 

Indenture) by transferring, or causing to be transferred, by wire transfer of immediately
available funds in Dollars, prior to 2:00 p.m., New York City time, on the due date of payment, to
an account maintained by such holder with a bank located in the continental United States the
amount to be distributed to such holder, for credit to the account of such holder maintained at
such bank. If the Indenture Trustee shall fail to make any such payment as provided in the
immediately foregoing sentence after its receipt of funds at the place and prior to the time
specified above, the Indenture Trustee, in its individual capacity and not as trustee, agrees to
compensate such holders for loss of use of funds at Debt Rate until such payment is made and the
Indenture Trustee shall be entitled to any interest earned on such funds until such payment is
made. Any payment made hereunder shall be made without any presentment or surrender of any
Equipment Note, except that, in the case of the final payment in respect of any Equipment Note,
such Equipment Note shall be surrendered to the Indenture Trustee for cancellation promptly after
such payment. Notwithstanding any other provision of this Trust Indenture to the contrary, the
Indenture Trustee shall not be required to make, or cause to be made, wire transfers as aforesaid
prior to the first Business Day on which it is practicable for the Indenture Trustee to do so in
view of the time of day when the funds to be so transferred were received by it if such funds were
received after 12:30 p.m., New York time, at the place of payment. Prior to the due presentment
for registration of transfer of any Equipment Note, the Owner and the Indenture Trustee shall deem
and treat the Person in whose name any Equipment Note is registered on the Equipment Note Register
as the absolute owner and holder of such Equipment Note for the purpose of receiving payment of all
amounts payable with respect to such Equipment Note and for all other purposes, and none of the
Owner or the Indenture Trustee shall be affected by any notice to the contrary. So long as any
signatory to the Participation Agreement or nominee thereof shall be a registered Note Holder, all
payments to it shall be made to the account of such Note Holder specified in Schedule 1 thereto and
otherwise in the manner provided in or pursuant to the Participation Agreement unless it shall have
specified some other account or manner of payment by notice to the Indenture Trustee consistent
with this Section 2.03.

               (b) The Indenture Trustee, as agent for the Owner, shall exclude and withhold at the
appropriate rate from each payment of Original Amount of, interest on, Make-Whole Amount, if any,
and other amounts due hereunder or under each Equipment Note (and such exclusion and withholding
shall constitute payment in respect of such Equipment Note) any and all United States withholding
taxes applicable thereto as required by Law. The Indenture Trustee agrees to act as such
withholding agent and, in connection therewith, whenever any present or future United States taxes
or similar charges are required to be withheld with respect to any amounts payable hereunder or in
respect of the Equipment Notes, to withhold such amounts and timely pay the same to the appropriate
authority in the name of and on behalf of the Note Holders, that it will file any necessary United
States withholding tax returns or statements when due, and that as promptly as possible after the
payment thereof it will deliver to each Note Holder (with a copy to the Owner) appropriate receipts
showing the payment thereof, together with such additional documentary evidence as any such Note
Holder may reasonably request from time to time.

          If a Note Holder which is a Non-U.S. Person has furnished to the Indenture Trustee a properly
completed, accurate and currently effective U.S. Internal Revenue Service Form W-8BEN, W-8EXP or
W-8IMY (or such successor form or forms as may be required by

13

 

the United States Treasury Department) during the calendar year in which the payment hereunder
or under the Equipment Note(s) held by such holder is made (but prior to the making of such
payment), or in any of the three preceding calendar years, and has not notified the Indenture
Trustee of the withdrawal or inaccuracy of such form prior to the date of such payment (and the
Indenture Trustee has no reason to believe that any information set forth in such form is
inaccurate), the Indenture Trustee shall withhold only the amount, if any, required by Law (after
taking into account any applicable exemptions properly claimed by the Note Holder) to be withheld
from payments hereunder or under the Equipment Notes held by such holder in respect of United
States federal income tax. If a Note Holder (x) which is a Non-U.S. Person has furnished to the
Indenture Trustee a properly completed, accurate and currently effective U.S. Internal Revenue
Service Form W-8ECI in duplicate (or such successor certificate, form or forms as may be required
by the United States Treasury Department as necessary in order to properly avoid withholding of
United States federal income tax) during the calendar year in which the payment hereunder or under
the Equipment Note(s) held by such holder is made (but prior to the making of such payment) or in
any of the three preceding calendar years, and has not notified the Indenture Trustee of the
withdrawal or inaccuracy of such certificate or form prior to the date of such payment (and the
Indenture Trustee has no reason to believe that any information set forth in such form is
inaccurate) or (y) which is a U.S. Person has furnished to the Indenture Trustee a properly
completed, accurate and currently effective U.S. Internal Revenue Service Form W-9, if applicable,
prior to a payment hereunder or under the Equipment Notes held by such holder, no amount shall be
withheld from payments in respect of United States federal income tax. If any Note Holder has
notified the Indenture Trustee that any of the foregoing forms or certificates is withdrawn or
inaccurate, or if such holder has not filed a form claiming an exemption from United States
withholding tax or if an applicable income tax convention, the Code or the regulations thereunder
or the administrative interpretation of any of the foregoing is at any time after the date hereof
amended to require such withholding of United States federal income taxes from payments under the
Equipment Notes held by such holder, the Indenture Trustee agrees to withhold from each payment due
to the relevant Note Holder withholding taxes at the appropriate rate under Law and will, on a
timely basis as more fully provided above, deposit such amounts with an authorized depository and
make such returns, statements, receipts and other documentary evidence in connection therewith as
required by Law.

          SECTION 2.04. Application of Payments

          In the case of each Equipment Note, each payment of Original Amount, Make-Whole Amount, if
any, and interest due thereon shall be applied:

     First: to the payment of Make-Whole Amount, if any, with respect to such Equipment
Note and any other amount (other than as covered by any of the following clauses) due
hereunder or under such Equipment Note;

     Second: to the payment of accrued interest on such Equipment Note (as well as any
interest on any overdue Original Amount, any overdue Make-Whole Amount, if any, and to the
extent permitted by Law, any overdue interest and any other overdue amounts thereunder) to
the date of such payment;

14

 

     Third: to the payment of the Original Amount of such Equipment Note (or a portion
thereof) then due thereunder; and

     Fourth: the balance, if any, remaining thereafter, to the payment of the Original
Amount of such Equipment Note remaining unpaid (provided that such Equipment Note shall not
be subject to redemption except as provided in Sections 2.09, 2.10 and 2.11 hereof).

The amounts paid pursuant to clause “Fourth” above shall be applied to the installments of Original
Amount of such Equipment Note in the inverse order of their maturity.

          SECTION 2.05. Termination of Interest in Collateral

          No Note Holder nor any other Indenture Indemnitee shall, as such, have any further interest
in, or other right with respect to, the Collateral when and if the Original Amount of, Make-Whole
Amount, if any, and interest on and other amounts due under all Equipment Notes held by such Note
Holder and all other sums then due and payable to such Note Holder, such Indenture Indemnitee or
the Indenture Trustee hereunder (including, without limitation, under the third paragraph of
Section 2.02 hereof) and under the other Operative Agreements by the Owner and all Related Secured
Obligations (collectively, the “Secured Obligations”) shall have been paid in full.

          SECTION 2.06. Registration Transfer and Exchange of Equipment Notes

          The Indenture Trustee shall keep a register (the “Equipment Note Register”) in which the
Indenture Trustee shall provide for the registration of Equipment Notes and the registration of
transfers of Equipment Notes. No such transfer shall be given effect unless and until registration
hereunder shall have occurred. The Equipment Note Register shall be kept at the Corporate Trust
Office of the Indenture Trustee. The Indenture Trustee is hereby appointed “Equipment Note
Registrar” for the purpose of registering Equipment Notes and transfers of Equipment Notes as
herein provided. A holder of any Equipment Note intending to exchange such Equipment Note shall
surrender such Equipment Note to the Indenture Trustee at the Corporate Trust Office, together with
a written request from the registered holder thereof for the issuance of a new Equipment Note,
specifying, in the case of a surrender for transfer, the name and address of the new holder or
holders. Upon surrender for registration of transfer of any Equipment Note, the Owner shall
execute, and the Indenture Trustee shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Equipment Notes of a like aggregate Original Amount and
of the same Series. At the option of the Note Holder, Equipment Notes may be exchanged for other
Equipment Notes of any authorized denominations of a like aggregate Original Amount, upon surrender
of the Equipment Notes to be exchanged to the Indenture Trustee at the Corporate Trust Office.
Whenever any Equipment Notes are so surrendered for exchange, the Owner shall execute, and the
Indenture Trustee shall authenticate and deliver, the Equipment Notes which the Note Holder making
the exchange is entitled to receive. All Equipment Notes issued upon any registration of transfer
or exchange of Equipment Notes (whether under this Section 2.06 or under Section 2.07 hereof or
otherwise under this Trust Indenture) shall be the valid obligations of the Owner evidencing the
same

15

 

respective obligations, and entitled to the same security and benefits under this Trust
Indenture, as the Equipment Notes surrendered upon such registration of transfer or exchange.
Every Equipment Note presented or surrendered for registration of transfer, shall (if so required
by the Indenture Trustee) be duly endorsed, or be accompanied by a written instrument of transfer
in form satisfactory to the Indenture Trustee duly executed by the Note Holder or such holder’s
attorney duly authorized in writing, and the Indenture Trustee shall require evidence satisfactory
to it as to the compliance of any such transfer with the Securities Act, and the securities Laws of
any applicable state. The Indenture Trustee shall make a notation on each new Equipment Note of
the amount of all payments of Original Amount previously made on the old Equipment Note or
Equipment Notes with respect to which such new Equipment Note is issued and the date to which
interest on such old Equipment Note or Equipment Notes has been paid. Interest shall be deemed to
have been paid on such new Equipment Note to the date on which interest shall have been paid on
such old Equipment Note, and all payments of the Original Amount marked on such new Equipment Note,
as provided above, shall be deemed to have been made thereon. The Owner shall not be required to
exchange any surrendered Equipment Notes as provided above during the ten-day period preceding the
due date of any payment on such Equipment Note. The Owner shall in all cases deem the Person in
whose name any Equipment Note shall have been issued and registered as the absolute owner and
holder of such Equipment Note for the purpose of receiving payment of all amounts payable by the
Owner with respect to such Equipment Note and for all purposes until a notice stating otherwise is
received from the Indenture Trustee and such change is reflected on the Equipment Note Register.
The Indenture Trustee will promptly notify the Owner of each registration of a transfer of an
Equipment Note. Any such transferee of an Equipment Note, by its acceptance of an Equipment Note,
(i) agrees to the provisions of this Trust Indenture and the Participation Agreement applicable to
Note Holders, including Sections 6.3, 6.4 and 9.1 thereof, and shall be deemed to have covenanted
to the parties to the Participation Agreement as to the matters covenanted by the original Note
Holder in the Participation Agreement and (ii) agrees to the restrictions set forth in Sections
4.1(a)(i) and 4.1(a)(iii) of the Intercreditor Agreement, and shall be deemed to have covenanted to
the parties to the Intercreditor Agreement not to give any direction, or otherwise authorize, the
Indenture Trustee to take any action that would violate Sections 4.1(a)(i) or 4.1(a)(iii) of the
Intercreditor Agreement. Subject to compliance by the Note Holder and its transferee (if any) of
the requirements set forth in this Section 2.06, the Indenture Trustee and the Owner shall use all
reasonable efforts to issue new Equipment Notes upon transfer or exchange within 10 Business Days
of the date an Equipment Note is surrendered for transfer or exchange.

          SECTION 2.07. Mutilated, Destroyed, Lost or Stolen Equipment Notes

          If any Equipment Note shall become mutilated, destroyed, lost or stolen, the Owner shall, upon
the written request of the holder of such Equipment Note, execute and the Indenture Trustee shall
authenticate and deliver in replacement thereof a new Equipment Note, payable in the same Original
Amount dated the same date and captioned as issued in connection with the Aircraft. If the
Equipment Note being replaced has become mutilated, such Equipment Note shall be surrendered to the
Indenture Trustee and a photocopy thereof shall be furnished to the Owner. If the Equipment Note
being replaced has been destroyed, lost or stolen, the holder of such Equipment Note shall furnish
to the Owner and the Indenture Trustee such security or indemnity as may be required by them to
save the Owner and the Indenture Trustee harmless and

16

 

evidence satisfactory to the Owner and the Indenture Trustee of the destruction, loss or theft
of such Equipment Note and of the ownership thereof. If a “qualified institutional buyer” of the
type referred to in paragraph (a)(1)(i)(A), (B), (D) or (E) of Rule 144A under the Securities Act
(a “QIB”) is the holder of any such destroyed, lost or stolen Equipment Note, then the written
indemnity of such QIB, signed by an authorized officer thereof, in favor of, delivered to and in
form reasonably satisfactory the Owner shall be accepted as satisfactory indemnity and security and
no further indemnity or security shall be required as a condition to the execution and delivery of
such new Equipment Note. Subject to compliance by the Note Holder with the requirements set forth
in this Section 2.07, the Indenture Trustee and the Owner shall use all reasonable efforts to issue
new Equipment Notes within 10 Business Days of the date of the written request therefor from the
Note Holder.

          SECTION 2.08. Payment of Expenses on Transfer; Cancellation

               (a) No service charge shall be made to a Note Holder for any registration of transfer or
exchange of Equipment Notes, but the Indenture Trustee, as Equipment Note Registrar, may require
payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Equipment Notes.

               (b) The Indenture Trustee shall cancel all Equipment Notes surrendered for replacement,
redemption, transfer, exchange, payment or cancellation and shall destroy the canceled Equipment
Notes.

          SECTION 2.09. Mandatory Redemptions of Equipment Notes

          On the date on which the Owner is required pursuant to Section 4.05 hereof to make payment for
an Event of Loss with respect to the Airframe, all of the Equipment Notes shall be redeemed in
whole at a redemption price equal to 100% of the unpaid Original Amount thereof, together with all
accrued interest thereon to the date of redemption and all other Secured Obligations (other than
Related Secured Obligations) owed or then due and payable to the Note Holders but without
Make-Whole Amount.

          SECTION 2.10. Optional Redemptions of Equipment Notes

               (a) All (but not less than all) of the Equipment Notes may be redeemed by the Owner upon at
least thirty (30) days’ revocable prior written notice to the Indenture Trustee and the Note
Holders, and such Equipment Notes shall be redeemed in whole at a redemption price equal to 100% of
the unpaid Original Amount thereof, together with accrued interest thereon to the date of
redemption and all other Secured Obligations (other than Related Secured Obligations) owed or then
due and payable to the Note Holders plus Make-Whole Amount, if any, provided that no
redemption shall be permitted under this Section 2.10(a) unless simultaneously with such redemption
all Related Series A Equipment Notes and Related Series B Equipment Notes shall also be redeemed.

               (b) All of the Series B Equipment Notes may be redeemed by the Owner upon at least thirty (30)
days’ revocable prior written notice to the Indenture Trustee and

17

 

the Note Holders of such Series, and such Equipment Notes shall be redeemed in whole at a
redemption price equal to 100% of the unpaid Original Amount thereof, together with accrued
interest thereon to the date of redemption and all other Secured Obligations (other than Related
Secured Obligations) owed or then due and payable to the Note Holders of such Series plus
Make-Whole Amount, if any; provided that no redemption shall be permitted under this
Section 2.10(b) unless the following conditions have been satisfied: (1) simultaneously with such
redemption, the Related Series B Equipment Notes shall also be redeemed; and (2) simultaneously
with such redemption, new Series B Equipment Notes shall be reissued in accordance with Section
4(a)(v) of the Note Purchase Agreement and Section 9.1(c) of the Intercreditor Agreement.

          SECTION 2.11. Redemptions; Notice of Redemption

               (a) No redemption of any Equipment Note may be made except to the extent and in the manner
expressly permitted by this Trust Indenture. No purchase of any Equipment Note may be made by the
Indenture Trustee.

               (b) Notice of redemption with respect to the Equipment Notes shall be given by the Indenture
Trustee by first-class mail, postage prepaid, mailed not less than twenty (20) nor more than sixty
(60) days prior to the applicable redemption date, to each Note Holder of such Equipment Notes to
be redeemed, at such Note Holder’s address appearing in the Equipment Note Register; provided that
such notice shall be revocable by written notice from the Owner to the Indenture Trustee given not
later than three days prior to the redemption date. All notices of redemption shall state: (1) the
redemption date, (2) the applicable basis for determining the redemption price, (3) that on the
redemption date, the redemption price will become due and payable upon each such Equipment Note,
and that, if any such Equipment Notes are then outstanding, interest on such Equipment Notes shall
cease to accrue on and after such redemption date, and (4) the place or places where such Equipment
Notes are to be surrendered for payment of the redemption price.

               (c) On or before the redemption date, the Owner (or any person on behalf of the Owner) shall,
to the extent an amount equal to the redemption price for the Equipment Notes to be redeemed on the
redemption date shall not then be held by the Indenture Trustee, deposit or cause to be deposited
with the Indenture Trustee by 12:30 p.m. New York time on the redemption date in immediately
available funds the redemption price of the Equipment Notes to be redeemed.

               (d) Notice of redemption having been given as aforesaid, the Equipment Notes to be redeemed
shall, on the redemption date, become due and payable at the Corporate Trust Office of the
Indenture Trustee or at any office or agency maintained for such purposes pursuant to Section 2.06,
and from and after such redemption date (unless there shall be a default in the payment of the
redemption price) any such Equipment Notes then outstanding shall cease to bear interest. Upon
surrender of any such Equipment Note for redemption in accordance with said notice, such Equipment
Note shall be redeemed at the redemption price. If any Equipment Note called for redemption shall
not be so paid upon surrender thereof for redemption, the principal amount thereof shall, until
paid, continue to bear interest from the

18

 

applicable redemption date at the interest rate in effect for such Equipment Note as of such
redemption date.

          SECTION 2.12. Subordination

               (a) The Owner, each Note Holder (by acceptance of its Equipment Notes of any Series) and each
Related Note Holder (by acceptance of its Related Equipment Note), hereby agree that no payment or
distribution shall be made on or in respect of the Secured Obligations owed to such Note Holder of
such Series or owed to such Related Note Holder, including any payment or distribution of cash,
property or securities after the commencement of a proceeding of the type referred to in Section
5.01(v), (vi) or (vii) hereof, except as expressly provided in Article III hereof.

               (b) By the acceptance of its Equipment Notes of any Series (other than Series A), each Note
Holder of such Series agrees that in the event that such Note Holder, in its capacity as a Note
Holder, shall receive any payment or distribution on any Secured Obligations in respect of such
Series which it is not entitled to receive under this Section 2.12 or Article III hereof, it will
hold any amount so received in trust for the Senior Holder and will forthwith turn over such
payment to the Indenture Trustee in the form received to be applied as provided in Article III
hereof. By the acceptance of its Related Equipment Notes (other than Related Series A Equipment
Notes), each Related Note Holder agrees that in the event that such Related Note Holder, in its
capacity as a Related Note Holder, shall receive any payment or distribution pursuant to this Trust
Indenture on any Related Secured Obligations which it is not entitled to receive under this Section
2.12 or Article III hereof, it will hold any amount so received in trust for the Senior Holder (as
defined in Section 2.12(c) hereof) and will forthwith turn over such payment to the Indenture
Trustee in the form received to be applied as provided in Article III hereof.

               (c) As used in this Section 2.12, the term “Senior Holder” shall mean (i) the Note Holders of
Series A Equipment Notes and Related Note Holders of the Related Series A Equipment Notes until the

          SECTION 3.05. Other Payments

          Any payments received by the Indenture Trustee for which no provision as to the application

          Prior to making any distribution under this Article III, the Indenture Trustee shall consult

Secured Obligations. The Indenture Trustee shall cooperate with the Related Indenture Trustees and
shall provide such information as shall be reasonably requested by each Related Indenture Trustee
to enable such Related Indenture Trustee to determine amounts distributable under Article III of
its Related Indenture.

          SECTION 3.07. Securities Account

          In furtherance of the provisions of Section 3.03 of this Trust Indenture, WTC agrees to act as
an Eligible Institution under this Trust Indenture in accordance with the provisions of this Trust
Indenture (in such capacity, the “Securities Intermediary”). Except in its capacity as the
Indenture Trustee, WTC waives any claim or lien against any Eligible Account it may have, by
operation of law or otherwise, for any amount owed to it by the Owner. The Securities Intermediary
hereby agrees that, notwithstanding anything to the contrary in this Trust Indenture, (i) any
amounts to be held by the Indenture Trustee pursuant to paragraph (iv) of clause “Third” of Section
3.03 and any investment earnings thereon or other Cash Equivalents will be credited to an Eligible
Account (the “Securities Account”) for which it is a “securities intermediary” (as defined in
Section 8-102(a)(14) of the NY UCC) and the Indenture Trustee is the “entitlement holder” (as
defined in Section 8-102(a)(7) of the NY UCC) of the “securities entitlement” (as defined in
Section 8-102(a)(17) of the NY UCC) with respect to each “financial asset” (as defined in Section
8-102(a)(9) of the NY UCC) credited to such Eligible Account, (ii) all such amounts, Cash
Equivalents and all other property acquired with cash credited to the

25

 

Securities Account will be credited to the Securities Account, (iii) all items of property
(whether cash, investment property, Cash Equivalents, other investments, securities, instruments or
other property) credited to the Securities Account will be treated as a “financial asset” under
Article 8 of the NY UCC, (iv) its “securities intermediary’s jurisdiction” (as defined in Section
8-110(e) of the NY UCC) with respect to the Securities Account is the State of New York, and (v)
all securities, instruments and other property in order or registered from and credited to the
Securities Account shall be payable to or to the order of, or registered in the name of, the
Securities Intermediary or shall be indorsed to the Securities Intermediary or in blank, and in no
case whatsoever shall any financial asset credited to the Securities Account be registered in the
name of the Owner, payable to or to the order of the Owner or specially indorsed to the Owner
except to the extent the foregoing have been specially endorsed by the Owner to the Securities
Intermediary or in blank. The Indenture Trustee agrees that it will hold (and will indicate
clearly in its books and records that it holds) its “securities entitlement” to the “financial
assets” credited to the Securities Account in trust for the benefit of the Note Holders and each of
the Indenture Indemnitees as set forth in this Trust Indenture. The Owner acknowledges that, by
reason of the Indenture Trustee being the “entitlement holder” in respect of the Securities Account
as provided above, the Indenture Trustee shall have the sole right and discretion, subject only to
the terms of this Trust Indenture, to give all “entitlement orders” (as defined in Section
8-102(a)(8) of the NY UCC) with respect to the Securities Account and any and all financial assets
and other property credited thereto to the exclusion of the Owner.

          SECTION 3.08. Payments to Owner.

          Any amount distributed hereunder by the Indenture Trustee to Owner shall be paid to Owner
(within the time limits contemplated by Section 2 03(a)) by wire transfer of funds of the type
received by the Indenture Trustee at such office and to such account or accounts of such entity or
entities as shall be designated by notice from the Owner to the Indenture Trustee from time to
time. The Owner hereby notifies the Indenture Trustee that unless and until the Indenture Trustee
receives notice to the contrary from the Owner, all amounts to be distributed to the Owner pursuant
to this Trust Indenture shall be distributed by wire transfer of funds of the type received by the
Indenture Trustee to the Owner’s account specified in Schedule 1 to the Participation Agreement.

or the maintenance, operation or use thereof except in compliance with Sections 4.02(c) and 4.02(d)
or (y) permit any action not permitted to the Owner hereunder.

          In the case of any lease permitted under this Section 4.02(b), the Owner will comply with the
notice requirement of Section 6.1.5 of the Participation Agreement and will include in such lease
appropriate provisions which (t) make such lease expressly subject and subordinate to all of the
terms of this Trust Indenture, including the rights of the Indenture Trustee to avoid such lease in
the exercise of its rights to repossession of the Airframe and Engines hereunder; (u) require the
Permitted Lessee to comply with the terms of Section 4.06; and (v) require that the Airframe or any
Engine subject thereto be used in accordance with the limitations applicable to the Owner’s
possession and use provided in this Trust Indenture. No lease permitted under this Section 4.02(b)
shall be entered into unless (w) the Owner shall provide written notice to the Indenture Trustee
(such notice in the event of a lease to a U.S. Air Carrier to be given promptly after entering into
any such lease or, in the case of a lease to any other Permitted Air Carrier, 10 days in advance of
entering into such lease); (x) the Owner shall furnish to the Indenture Trustee evidence reasonably
satisfactory to the Indenture Trustee that the insurance required by Section 4.06 remains in
effect; (y) 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 and
International Interest (subject to Permitted Liens) of the Indenture Trustee in the Aircraft,
Airframe and Engines; and (z) the Owner shall reimburse the Indenture Trustee for all of its
reasonable out-of-pocket fees and expenses, including, without limitation, reasonable fees and
disbursements of counsel, incurred by the Indenture Trustee in connection with any such lease.
Except as otherwise provided herein and without in any way relieving the Owner from its primary
obligation for the performance of its obligations under this Trust Indenture, the Owner may in its
sole discretion permit a lessee to exercise any or all rights which the Owner would be entitled to
exercise under Sections 4.02 and 4.04, and may cause a lessee to perform any or all of the Owner’s
obligations under Article IV, and the Indenture

29

 

Trustee agrees to accept actual and full performance thereof by a lessee in lieu of
performance by the Owner.

          Any Wet Lease or similar arrangement under which the Owner maintains operational control of
the Aircraft shall not constitute a deliver, transfer or relinquishment of possession of the
Aircraft for purposes of this Section.

          The Indenture Trustee hereby agrees, and each Note Holder and Related Note Holder by
acceptance of an Equipment Note and a Related Equipment Note, respectively, agrees, for the benefit
of each lessor, conditional seller, indenture trustee or secured party of any engine leased to, or
purchased by, the Owner or any Permitted Lessee subject to a lease, conditional sale, trust
indenture or other security agreement that the Indenture Trustee, each Note Holder and Related Note
Holder and their respective successors and assigns will not acquire or claim, as against such
lessor, conditional seller, indenture trustee or secured party, any right, title or interest in any
engine as the result of such engine being installed on the Airframe at any time while such engine
is subject to such lease, conditional sale, trust indenture or other security agreement and owned
by such lessor or conditional seller or subject to a trust indenture or security interest in favor
of such indenture trustee or secured party.

                    (c) Operation and Use. So long as the Aircraft, Airframe or any Engine is subject to
the Lien of this Trust Indenture, the Owner shall not operate, use or locate the Aircraft, Airframe
or any Engine, or allow the Aircraft, Airframe or any Engine to be operated, used or located, (i)
in any area excluded from coverage by any insurance required by the terms of Section 4.06, except
in the case of a requisition by the U.S. Government where the Owner 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 4.06
covering such area, or (ii) in any recognized area of hostilities unless covered in accordance with
Section 4.06 by war risk insurance, or in either case unless the Aircraft, the Airframe or any
Engine is only temporarily operated, used or located in such area as a result of an emergency,
equipment malfunction, navigational error, hijacking, weather condition, medical emergency or other
circumstances beyond the reasonable control of the Owner (or any Permitted Lessee), so long as the
Owner (or any Permitted Lessee) diligently and in good faith proceeds to remove the Aircraft from
such area. The Owner shall also have the right to operate the Aircraft without having on board the
original registration certificate or airworthiness certificate in the event that either or both
such certificates disappear from the Aircraft, but only to the extent permitted by Exemption No.
5318 of the FAA Regulations or other similar exemption. So long as the Aircraft, the Airframe or
any Engine is subject to the Lien of this Trust Indenture, the Owner shall not permit such
Aircraft, Airframe or any 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
over the Aircraft that is binding on or applicable to such Aircraft, Airframe or Engine or (y) in
violation of any airworthiness certificate, license or registration of any Government Entity
relating to the Aircraft, the Airframe or any Engine, except (i) immaterial or non-recurring
violations with respect to which corrective measures are taken promptly by the Owner or 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 relating to any such certificate, license or
registration is being contested in good

30

 

faith by the Owner or Permitted Lessee in any reasonable manner which does not involve any
material risk of the sale, forfeiture or loss of the Aircraft, Airframe or any Engine, any material
risk of criminal liability or material civil penalty against the Indenture Trustee or impair the
Indenture Trustee’s security interest or International Interest in the Aircraft, Airframe or any
Engine. Owner shall not be in default under or required to take any action set forth in the
preceding sentence if it is not possible for Owner to comply with the laws of a jurisdiction other
than the United States (or other jurisdiction in which the Aircraft is registered) because of a
conflict with the Laws of the United States (or other jurisdiction in which the Aircraft is
registered).

                    (d) Maintenance and Repair. So long as the Aircraft, Airframe or any Engine is
subject to the Lien of this Trust Indenture, the Owner shall cause the Aircraft, Airframe and each
Engine to be maintained, serviced, repaired and overhauled in accordance with (i) maintenance
standards required by or substantially equivalent to those required by the Owner’s FAA approved
maintenance program or while registered in another jurisdiction, under the applicable maintenance
standards required by the Aviation Authority in such jurisdiction (provided, that in any
case, if operated under the maintenance program of an Aviation Authority other the FAA, the
Aircraft, Airframe and each Engine shall be maintained according to standards substantially
equivalent to those required by the Aviation Authority of any of Australia, Austria, Belgium,
Canada, Denmark, Finland, France, Germany, Ireland, Italy, Japan, the Netherlands, New Zealand,
Norway, Spain, Sweden, Switzerland or the United Kingdom) so as to (A) keep the Aircraft, the
Airframe and each Engine in as good operating condition as on the Closing Date, ordinary wear and
tear excepted, (B) keep the Aircraft in such operating condition as may be necessary to enable the
applicable airworthiness certification of such Aircraft to be maintained under the regulations of
the FAA or other Aviation Authority then having jurisdiction over the operation of the Aircraft,
except (w) during temporary periods of storage in accordance with applicable regulations, (x)
maintenance, testing and modification permitted hereunder, (y) during periods when the FAA or such
other Aviation Authority has revoked or suspended the airworthiness certificates for Similar
Aircraft or (z) with respect to minor or nonrecurring violations with respect to which corrective
measures are taken upon discovery thereof and except to the extent the Owner or Permitted Lessee is
promptly contesting in good faith the validity or application of any such Law or requirement
relating to any such certificate, license or registration in any reasonable manner which does not
create a material risk of sale, loss or forfeiture of the Aircraft, the Airframe or any Engine or
the interest of the Indenture Trustee therein or any material risk of criminal liability or
material civil penalty against the Indenture Trustee; and (ii) except during periods when a
Permitted Lease is in effect, the same standards as the Owner uses with respect to similar aircraft
of similar size in its fleet operated by the Owner in similar circumstances and, during any period
in which a Permitted Lease is in effect, the same standards used by the Permitted Lessee with
respect to similar aircraft of similar size in its fleet and operated by the Permitted Lessee in
similar circumstances (it being understood that this clause (ii) shall not limit the Owner’s
obligations under the preceding clause (i)). The Owner further agrees that the Aircraft, Airframe
and Engines will be maintained, used, serviced, repaired, overhauled or inspected in compliance
with each applicable airworthiness certificate, license and registration relating to the Aircraft,
Airframe or any Engine issued by the FAA (or other applicable Aviation Authority). The Owner shall
maintain or cause to be maintained the Aircraft Documents in the English language.

31

 

                    (e) Registration. The Owner on or prior to the date of the Closing shall cause the
Aircraft to be duly registered in its name under the Act and except as otherwise permitted by this
Section 4.02(e) at all times thereafter shall cause the Aircraft to remain so registered. So long
as no Special Default or Event of Default shall have occurred and be continuing, the Owner may, by
written notice to the Indenture Trustee, request to change the country of registration of the
Aircraft. Any such change in registration shall be effected only in compliance with, and subject
to all of the conditions set forth in, Section 6.4.5 of the Participation Agreement. Unless the
Trust Indenture has been discharged, the Owner shall also cause the Trust Indenture to be duly
recorded and at all times maintained of record as a first-priority perfected mortgage (subject to
Permitted Liens) on the Aircraft, the Airframe and each of the Engines (except to the extent such
perfection or priority cannot be maintained solely as a result of the failure by the Indenture
Trustee to execute and deliver any necessary documents). Unless the Lien of this Indenture has
been discharged, the Owner shall cause the International Interest granted under this Indenture in
favor of the Indenture Trustee in each Airframe and Engine to be registered on the International
Registry as an International Interest on such Airframe and Engine, subject to the Indenture Trustee
providing its consent to the International Registry with respect thereto.

                    (f) Markings. If permitted by applicable Law, on or reasonably promptly after the
Closing Date, the Owner will cause to be affixed to, and maintained in, the cockpit of the Airframe
and on each 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 of Wilmington Trust Company,
not in its individual capacity but solely as Indenture Trustee.” Such placards may be removed
temporarily, if necessary, in the course of maintenance of the Airframe or Engines. If any such
placard is damaged or becomes illegible, the Owner shall promptly replace it with a placard
complying with the requirements of this Section.

          SECTION 4.03. Inspection

                    (a) At all reasonable times upon at least 15 Business Days prior written notice to Owner, so
long as the Aircraft is subject to the Lien of this Trust Indenture, the Indenture Trustee and its
authorized representatives (the “Inspecting Parties”) may (not more than once every twelve (12)
months unless an Event of Default has occurred and is continuing then such inspection right shall
not be so limited) inspect the Aircraft, Airframe and Engines (including without limitation, the
Aircraft Documents) and any such Inspecting Party may make copies of such Aircraft Documents not
reasonably deemed confidential by the Owner or such Permitted Lessee.

                    (b) Any inspection of the Aircraft hereunder shall be limited to a visual, walk-around
inspection and shall not include the opening of any panels, bays or the like or other components of
the Aircraft, and no such inspection shall interfere with the Owner’s or any Permitted Lessee’s
maintenance and operation of the Aircraft, Airframe and Engines. Any inspection shall be subject
to the Owner’s safety and security rules applicable to the location of the Aircraft.

32

 

                    (c) With respect to such rights of inspection, the Indenture Trustee 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 4.03(a)).

          SECTION 4.04. Replacement and Pooling of Parts, Alterations, Modifications and Additions;
Substitution of Engines

                    (a) Replacement of Parts. Except as otherwise provided herein, so long as the
Airframe or Engine is subject to the Lien of this Trust Indenture, the Owner, 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 be incorporated or installed in or
attached to the Aircraft, Airframe or any Engine and 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 paragraph (d) of this Section
4.04 or if the Airframe or Engine to which a Part relates has suffered an Event of Loss. In
addition, the Owner may, at its own cost and expense, or may permit a Permitted Lessee at its own
cost and expense 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,
however, that the Owner, except as otherwise provided herein, at its own cost and expense,
will, or will cause a Permitted Lessee at its own cost and expense to, replace such Parts as
promptly as practicable. All replacement parts shall be free and clear of all Liens, except for
Permitted Liens and pooling arrangements to the extent permitted by Section 4.04(c) below (and
except in the case of replacement property temporarily installed on an emergency basis) and shall
be in good operating condition and have a value and utility not less than the value and utility of
the Parts replaced (assuming such replaced Parts were in the condition required hereunder).

                    (b) Parts. Except as otherwise provided herein, any Part at any time removed from the
Airframe or any Engine shall remain subject to the Lien of this Trust Indenture, no matter where
located, until such time as such Part shall be replaced by a part that has been incorporated or
installed in or attached to such Airframe or any Engine and that meets the requirements for
replacement parts specified above. Immediately upon any replacement part becoming incorporated or
installed in or attached to such Airframe or any Engine as provided in Section 4.04(a), without
further act, (i) the replaced Part shall thereupon be free and clear of all rights of the Indenture
Trustee and shall no longer be deemed a Part hereunder, and (ii) such replacement part shall become
a Part subject to this Trust Indenture and be deemed part of such Airframe or any Engine, as the
case may be, for all purposes hereof to the same extent as the Parts originally incorporated or
installed in or attached to such Airframe or any Engine. Upon request of Owner, the Indenture
Trustee shall, at Owner’s expense, execute and deliver to Owner such documents as may be reasonably
required to evidence the release of any replaced Part from the Lien of the Indenture.

33

 

                    (c) Pooling of Parts. Any Part removed from the Aircraft, Airframe or an Engine may
be subjected by the Owner or a Permitted Lessee to a normal pooling arrangement customary in the
airline industry and entered into in the ordinary course of business of the Owner or Permitted
Lessee, provided that the part replacing such removed Part shall be incorporated or installed in or
attached to such Airframe or any Engine in accordance with Sections 4.04(a) and 4.04(b) as promptly
as practicable after the removal of such removed Part. In addition, any replacement part when
incorporated or installed in or attached to the Airframe or any Engine may be owned by any third
party, subject to a normal pooling arrangement, so long as the Owner or a Permitted Lessee, at its
own cost and expense, as promptly thereafter as reasonably possible, either (i) causes such
replacement part to become subject to the Lien of this Trust Indenture, free and clear of all Liens
except Permitted Liens, at which time such replacement part shall become a Part or (ii) replaces
(or causes to be replaced) such replacement part by incorporating or installing in or attaching to
the Aircraft, Airframe or any Engine a further replacement part owned by the Owner free and clear
of all Liens except Permitted Liens and which shall become subject to the Lien of this Trust
Indenture in accordance with Section 4.04(b).

                    (d) Alterations, Modifications and Additions. The Owner shall, or shall cause a
Permitted Lessee to, make (or cause to be made) alterations and modifications in and additions to
the Aircraft, Airframe and each Engine as may be required to be made from time to time to meet the
applicable standards of the FAA or other Aviation Authority having jurisdiction over the operation
of the Aircraft, to the extent made mandatory in respect of the Aircraft (a “Mandatory
Modification”); except for (i) immaterial and non-recurring violations with respect to which
corrective measures are being taken promptly by Owner or a Permitted Lessee and (ii) any law, rule,
regulation or order the validity or application of which is being contested in good faith by the
Owner or any Permitted Lessee in any reasonable manner which does not materially adversely affect
the Indenture Trustee’s interest in the Aircraft, does not impair the Indenture Trustee’s security
interest or International Interest in the Aircraft and does not involve any material risk of sale,
forfeiture or loss of the Aircraft or the interest of the Indenture Trustee therein or any material
risk of material civil penalty or any material risk of criminal liability being imposed on the
Indenture Trustee or the holder of any Equipment Note. In addition, the Owner, at its own expense,
may, or may permit a Permitted Lessee at its own cost and expense to, from time to time make or
cause to be made such alterations and modifications in and additions to the Airframe or any Engine
(each an “Optional Modification”) as the Owner or such Permitted Lessee may deem desirable in the
proper conduct of its business including, without limitation, removal of Parts which the Owner
deems are obsolete or no longer suitable or appropriate for use in the Aircraft, Airframe or such
Engine; provided, however, that no such Optional Modification shall (i) materially
diminish the fair market value, utility, or useful life of the Aircraft or any Engine below its
fair market value, utility or useful life immediately prior to such Optional Modification (assuming
the Aircraft or such Engine was in the condition required by this Trust Indenture immediately prior
to such Optional Modification) or (ii) cause the Aircraft to cease to have the applicable standard
certificate of airworthiness except that such certificate of airworthiness temporarily may be
replaced by an experimental certificate during the process of implementing and testing such
Optional Modification and securing related FAA re-certification of the Aircraft. For the avoidance
of doubt, Owner may make alterations in the passenger configuration of the Aircraft and such
alterations shall not

34

 

constitute an Optional Modification. All Parts incorporated or installed in or attached to
any Airframe or any Engine as the result of any alteration, modification or addition effected by
the Owner shall be free and clear of any Liens except Permitted Liens and become subject to the
Lien of this Trust Indenture; provided that the Owner or any Permitted Lessee may, at any
time so long as the Airframe or any Engine is subject to the Lien of this Trust Indenture, remove
any such Part (such Part being referred to herein as a “Removable Part”) from such Airframe
or an Engine if (i) such Part is in addition to, and not in replacement of or in substitution for,
any Part originally incorporated or installed in or attached to such Airframe or any Engine at the
time of delivery thereof hereunder or any Part in replacement of, or in substitution for, any such
original Part, (ii) such Part is not required to be incorporated or installed in or attached or
added to such Airframe or any Engine pursuant to the terms of Section 4.02(d) or the first sentence
of this Section 4.04(d) and (iii) such Part can be removed from such Airframe or any Engine without
materially diminishing the fair market value, utility or remaining useful life which such Airframe
or any Engine would have had at the time of removal had such removal not been effected by the
Owner, assuming the Aircraft was otherwise maintained in the condition required by this Trust
Indenture and such Removable Part had not been incorporated or installed in or attached to the
Aircraft, Airframe or such Engine. Upon the removal by the Owner of any such Part as above
provided in this Section 4.04(d), title thereto shall, without further act, be free and clear of
all rights of the Indenture Trustee and such Part shall no longer be deemed a Part hereunder.
Removable Parts may be leased from or financed by third parties other than the Indenture Trustee.
Notwithstanding any other provision of this Indenture, Owner may, at any time, install or permit to
be installed in the Aircraft Passenger Convenience Equipment owned by Owner or any Permitted Lessee
or by third parties and leased or otherwise furnished to Owner in the ordinary course of business
(including pursuant to a conditional sale contract, a licence or otherwise), and Owner may remove
(and not replace) or permit to be removed (and not replaced) the same, and Indenture Trustee 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 Trust Indenture, it being acknowledged and
agreed, however, that in no event shall the installation of any such Passenger Convenience
Equipment impair or otherwise affect the rights and remedies of the Indenture Trustee hereunder and
under applicable law.

                    (e) Substitution of Engines. Upon the occurrence of an Event of Loss with respect to
an Engine under circumstances in which an Event of Loss with respect to the Airframe has not
occurred, the Owner shall promptly (and in any event within fifteen (15) days after such
occurrence) give the Indenture Trustee written notice of such Event of Loss. The Owner shall have
the right at its option at any time, on at least five (5) Business Days’ prior notice to the
Indenture Trustee, to substitute, and if an Event of Loss shall have occurred with respect to an
Engine under circumstances in which an Event of Loss with respect to the Airframe has not occurred,
shall within one hundred and twenty (120) days of the occurrence of such Event of Loss substitute,
a Replacement Engine for any Engine. In such event, immediately upon the effectiveness of such
substitution and without further act, (i) the replaced Engine shall thereupon be free and clear of
all rights of the Indenture Trustee and the Lien of this Trust Indenture and shall no longer be
deemed an Engine hereunder and (ii) such Replacement Engine shall become subject to this Trust
Indenture and be deemed part of the Aircraft for all purposes hereof to the same extent as the
replaced Engine. Such Replacement Engine shall be an engine manufactured by Engine Manufacturer
that is the same model as the Engine to be replaced

35

 

thereby, or an improved model, and that is suitable for installation and use on the Airframe,
and that has a value, utility and remaining useful life (without regard to hours and cycles
remaining until overhaul) at least equal to the Engine to be replaced thereby (assuming that such
Engine had been maintained in accordance with this Trust Indenture). The Owner’s right to make a
replacement hereunder shall be subject to the fulfillment (which may be simultaneous with such
replacement) of the following conditions precedent at the Owner’s sole cost and expense, and the
Indenture Trustee agrees to cooperate with the Owner to the extent necessary to enable it to timely
satisfy such conditions:

                    (i) an executed counterpart of each of the following documents shall be delivered to the
Indenture Trustee:

     (A) a Trust Indenture Supplement covering the Replacement Engine, which shall
have been duly filed for recordation pursuant to the Act or such other applicable
law of the jurisdiction other than the United States in which the Aircraft of which
such Engine is a part is registered in accordance with Section 4.02(e), as the case
may be;

     (B) a full warranty bill of sale (as to title), covering the Replacement
Engine, executed by the former owner thereof in favor of the Owner (or, at the
Owner’s option, other evidence of the Owner’s ownership of such Replacement Engine,
reasonably satisfactory to the Indenture Trustee); and

     (C) UCC financing statements covering the security interests created by this
Trust Indenture (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 Indenture
Trustee to protect the security interests of the Indenture Trustee in the
Replacement Engine;

                    (ii) the Owner shall cause to be delivered to the Indenture Trustee an opinion of counsel to
the effect that the Lien of this Trust Indenture continues to be in full force and effect with
respect to the Replacement Engine and such evidence of compliance with the insurance provisions of
Section 4.06 with respect to such Replacement Engine as the Indenture Trustee shall reasonably
request;

                    (iii) promptly after the filing of the Trust Indenture Supplement, the Owner shall have caused
to be furnished to the Indenture Trustee an opinion of the Owner’s aviation law counsel reasonably
satisfactory to the Indenture Trustee addressed to the Indenture Trustee as to the due filing for
recordation of the Trust Indenture 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 the Aircraft
is registered in accordance with Section 4.02(e), as the case may be, and the registration (which
the Owner shall have caused to be effected) with the International Registry of the sale to the
Owner of such Replacement Engine (if occurring after February 28, 2006) and the International
Interest granted under such Trust Indenture Supplement with respect to such Replacement Engine; and

36

 

                    (iv) the Owner shall have furnished to the Indenture Trustee a certificate of a qualified
aircraft engineer (who may be an employee of the Owner) or an independent appraiser 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 had been maintained in accordance with this Trust Indenture).

Upon satisfaction of all conditions to such substitution, (x) the Indenture Trustee shall execute
and deliver to the Owner such documents and instruments, prepared at the Owner’s expense, as the
Owner shall reasonably request to evidence the release of such replaced Engine from the Lien of
this Trust Indenture, (y) the Indenture Trustee shall assign to the Owner all claims it may have
against any other Person relating to any Event of Loss giving rise to such substitution and (z) the
Owner shall receive all insurance proceeds (other than those reserved to others under Section
4.06(b)) and proceeds in respect of any Event of Loss giving rise to such replacement to the extent
not previously applied to the purchase price of the Replacement Engine as provided in Section
4.05(d).

          SECTION 4.05. Loss, Destruction or Requisition

               (a) Event of Loss With Respect to the Airframe. Upon the occurrence of an Event of
Loss with respect to the Airframe, the Owner shall promptly (and in any event within fifteen (15)
days after such occurrence) give the Indenture Trustee written notice of such Event of Loss. The
Owner shall, within forty-five (45) days after such occurrence, give the Indenture Trustee written
notice of the Owner’s election to either replace the Airframe as provided under Section 4.05(a)(i)
or to make payment in respect of such Event of Loss as provided under Section 4.05(a)(ii) (it being
agreed that if the Owner shall not have given the Indenture Trustee such notice of such election
within the above specified time period, the Owner shall be deemed to have elected to make payment
in respect of such Event of Loss as provided under Section 4.05(a)(ii)):

                    (i) if the Owner elects to replace the Airframe, the Owner shall, subject to the satisfaction
of the conditions contained in Section 4.05(c), as promptly as possible and in any event within one
hundred and twenty (120) days after the occurrence of such Event of Loss, cause to be subjected to
the Lien of this Trust Indenture, in replacement of the Airframe with respect to which the Event of
Loss occurred, a Replacement Airframe and, if any Engine shall have been installed on the Airframe
when it suffered the Event of Loss, a Replacement Engine therefor, such Replacement Airframe and
Replacement Engines to be free and clear of all Liens except Permitted Liens and to have a value,
utility and remaining useful life (without regard to hours or cycles remaining until the next
regular maintenance check) at least equal to the Airframe or Engine, as the case may be, to be
replaced thereby (assuming that such Airframe or Engine had been maintained in accordance with this
Trust Indenture); provided that if the Owner shall not perform its obligation to
effect such replacement under this clause (i) during the 120-day period of time provided herein, it
shall pay the amounts required to be paid pursuant to and within the time frame specified in clause
(ii) below; or

37

 

                    (ii) if the Owner elects to make a payment in respect of such Event of Loss of the Airframe,
the Owner shall make a payment to the Indenture Trustee for purposes of redeeming Equipment Notes
in accordance with Section 2.09 hereof on a date on or before the Business Day next following the
earlier of (x) the one hundred and twentieth (120)th day following the date of the occurrence of
such Event of Loss, and (y) the fourth (4th) Business Day following the receipt of
insurance proceeds with respect to such Event of Loss (but in any event not earlier than the date
of the Owner’s election under Section 4.05(a) to make payment under this Section 4.05 (a)(ii)); and
upon such payment and payment of all other Secured Obligations then due and payable, the Indenture
Trustee shall, at the cost and expense of the Owner, release from the Lien of this Trust Indenture
the Airframe and the Engines, by executing and delivering to the Owner all documents and
instruments as the Owner may reasonably request to evidence such release.

               (b) Effect of Replacement. Should the Owner have provided a Replacement Airframe and
Replacement Engines, if any, as provided for in Section 4.05(a)(i), (i) the Lien of this Trust
Indenture shall continue with respect to such Replacement Airframe and Replacement Engines, if any,
as though no Event of Loss had occurred; (ii) the Indenture Trustee shall, at the cost and expense
of the Owner, release from the Lien of this Trust Indenture the replaced Airframe and Engines, if
any, by executing and delivering to the Owner such documents and instruments as the Owner may
reasonably request to evidence such release; and (iii) in the case of a replacement upon an Event
of Loss, the Indenture Trustee shall assign to the Owner all claims the Indenture Trustee may have
against any other Person arising from the Event of Loss and the Owner shall receive all insurance
proceeds (other than those reserved to others under Section 4.06(b)) and proceeds from any award in
respect of condemnation, confiscation, seizure or requisition, including any investment interest
thereon, to the extent not previously applied to the purchase price of the Replacement Airframe and
Replacement Engines, if any, as provided in Section 4.05(d).

               (c) Conditions to Airframe and Engine Replacement. The Owner’s right to substitute a
Replacement Airframe and Replacement Engines, if any, as provided in Section 4.05(a)(i) shall be
subject to the fulfillment, at the Owner’s sole cost and expense, in addition to the conditions
contained in such Section 4.05(a)(i), of the following conditions precedent:

                    (i) on the date when the Replacement Airframe and Replacement Engines, if any, is subjected to
the Lien of this Trust Indenture (such date being referred to in this Section 4.05 as the
“Replacement Closing Date”), an executed counterpart of each of the following documents (or, in the
case of the FAA Bill of Sale and full warranty bill of sale referred to below, a photocopy thereof)
shall have been delivered to the Indenture Trustee:

     (A) a Trust Indenture Supplement covering the Replacement Airframe and
Replacement Engines, if any, which shall have been duly filed for recordation
pursuant to the Act or such other applicable law of such jurisdiction other than the
United States in which the Replacement Airframe and Replacement Engines, if any, are
to be registered in accordance with Section 4.02(e), as the case may be;

38

 

     (B) an FAA Bill of Sale (or a comparable document, if any, of another Aviation
Authority, if applicable) covering the Replacement Airframe and Replacement Engines,
if any, executed by the former owner thereof in favor of the Owner;

     (C) a full warranty (as to title) bill of sale, covering the Replacement
Airframe and Replacement Engines, if any, executed by the former owner thereof in
favor of the Owner (or, at the Owner’s option, other evidence of the Owner’s
ownership of such Replacement Airframe and Replacement Engines, if any, reasonably
satisfactory to the Indenture Trustee); and

     (D) UCC financing statements (or any similar statements or other documents
required to be filed or delivered pursuant to the laws of the jurisdiction in which
the Replacement Airframe and Replacement Engines, if any, may be registered in
accordance with Section 4.02(e)) as are deemed necessary or desirable by counsel for
the Indenture Trustee to protect the security interests of the Indenture Trustee in
the Replacement Airframe and Replacement Engines, if any;

                    (ii) the Replacement Airframe and Replacement Engines, if any, shall be of the same model as
the Airframe or Engines, as the case may be, or an improved model of such aircraft or engines of
the manufacturer thereof, shall have a value and utility (without regard to hours or cycles
remaining until the next regular maintenance check) at least equal to, and be in as good operating
condition and repair as, the Airframe and any Engines replaced (assuming such Airframe and Engines
had been maintained in accordance with this Trust Indenture);

                    (iii) the Indenture Trustee (acting directly or by authorization to its special counsel) shall
have received satisfactory evidence as to the compliance with Section 4.06 with respect to the
Replacement Airframe and Replacement Engines, if any;

                    (iv) on the Replacement Closing Date, (A) the Owner shall cause the Replacement Airframe and
Replacement Engines, if any, to be subject to the Lien of this Trust Indenture free and clear of

registered on the International Registry as a sale or an International Interest, respectively;

                    (v) the Indenture Trustee at the expense of the Owner, shall have received (acting directly or
by authorization to its special counsel) (A) an opinion of

counsel, addressed to the Indenture Trustee, to the effect that the Replacement Airframe and
Replacement Engine, if any, has or have duly been made subject to the Lien of this Trust Indenture,
and the Indenture Trustee will be entitled to the benefits of Section 1110 with respect to the
Replacement Airframe, 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 the Indenture
Trustee;

                    (vi) promptly after the filing of the Trust Indenture Supplement, the Owner shall cause to be
furnished to the Indenture Trustee an opinion of the Owner’s aviation law counsel reasonably
satisfactory to and addressed to the Indenture Trustee as to the due registration of any such
Replacement Airframe and the due filing for recordation of each Trust Indenture Supplement with
respect to such Replacement Airframe or Replacement Engine under the Act or such other applicable
law of the jurisdiction other than the United States in which the Replacement Airframe is to be
registered in accordance with Section 4.02(e), as the case may be, and the registration (which the
Owner shall have caused to be effected) with the International Registry of the sale of such
Replacement Airframe and Replacement Engine(s), if any, to the Owner (if occurring after February
28, 2006) and of the International Interest granted under the Trust Indenture Supplement with
respect to such Replacement Aircraft and Replacement Engine(s), if any; and

                    (vii) the Owner shall have furnished to the Indenture Trustee a certificate of a qualified
aircraft engineer (who may be an employee of the Owner) or an independent appraiser certifying that
the Replacement Airframe and Replacement Engines, if any, have a value and utility and remaining
useful life (without regard to hours and cycles remaining until overhaul) at least equal to the
Airframe and any Engines so replaced (assuming that such Airframe and Engines had been maintained
in accordance with this Trust Indenture).

               (d) Non-Insurance Payments Received on Account of an Event of Loss. Any amounts,
other than insurance proceeds in respect of damage or loss not constituting an Event of Loss (the
application of which is provided for in Annex B), received at any time by the Indenture Trustee or
the Owner from any Government Entity or any other Person in respect of any Event of Loss will be
applied as follows:

     (i) If such amounts are received with respect to the Airframe, and any Engine
installed thereon at the time of such Event of Loss, upon compliance by the Owner
with the applicable terms of Section 4.05(c) with respect to the Event of Loss for
which such amounts are received, such amounts shall be paid over to, or retained by,
the Owner;

     (ii) If such amounts are received with respect to an Engine (other than an
Engine installed on the Airframe at the time such Airframe suffers an Event of
Loss), upon compliance by the Owner with the applicable terms of Section 4.04(e)
with respect to the Event of Loss for which such amounts are received, such amounts
shall be paid over to, or retained by, the Owner;

40

 

     (iii) If such amounts are received, in whole or in part, with respect to the
Airframe, and the Owner makes, has made or is deemed to have made the election set
forth in Section 4.05(a)(ii), such amounts shall be applied as follows:

          first, if the sum described in Section 4.05(a)(ii) has not then been
paid in full by the Owner, such amounts shall be paid to the Indenture Trustee to
the extent necessary to pay in full such sum; and

          second, the remainder, if any, shall be paid to the Owner.

               (e) Requisition for Use. In the event of a requisition for use by any Government
Entity of the Airframe and the Engines, if any, or engines installed on such Airframe while such
Airframe is subject to the Lien of this Trust Indenture, the Owner shall promptly notify the
Indenture Trustee of such requisition and all of the Owner’s obligations under this Trust Indenture
shall continue to the same extent as if such requisition had not occurred except to the extent that
the performance or observance of any obligation by the Owner shall have been prevented or delayed
by such requisition; provided that the Owner’s obligations under this Section 4.05
with respect to the occurrence of an Event of Loss for the payment of money and under Section 4.06
(except while an assumption of liability by the U.S. Government of the scope referred to in Section
4.02(c) is in effect) shall not be reduced or delayed by such requisition. Any payments received
by the Indenture Trustee or the Owner or Permitted Lessee from such Government Entity with respect
to such requisition of use shall be paid over to, or retained by, the Owner. In the event of an
Event of Loss of an Engine resulting from the requisition for use by a Government Entity of such
Engine (but not the Airframe), the Owner will replace such Engine hereunder by complying with the
terms of Section 4.04(e) and any payments received by the Indenture Trustee or the Owner from such
Government Entity with respect to such requisition shall be paid over to, or retained by, the
Owner.

               (f) Certain Payments to be Held As Security. Any amount referred to in this Section
4.05 or Section 4.06 which is payable or creditable to, or retainable by, the Owner shall not be
paid or credited to, or retained by the Owner if at the time of such payment, credit or retention a
Special Default or an Event of Default shall have occurred and be continuing, but shall be paid to
and held by the Indenture Trustee as security for the obligations of the Owner under this Trust
Indenture and the Operative Agreements, and at such time as there shall not be continuing any such
Special Default or Event of Default such amount and any gain realized as a result of investments
required to be made pursuant to Section 6.06 shall to the extent not theretofore applied as
provided herein, be paid over to the Owner.

          SECTION 4.06. Insurance

               (a) Owner’s Obligation to Insure. The Owner shall comply with, or cause to be
complied with, each of the provisions of Annex B, which provisions are hereby incorporated by this
reference as if set forth in full herein.

               (b) Insurance for Own Account. Nothing in Section 4.06 shall limit or prohibit (a)
Owner from maintaining the policies of insurance required under Annex B with higher limits than
those specified in Annex B, or (b) Indenture Trustee from obtaining insurance

41

 

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 the Owner pursuant to this Section 4.06 and
Annex B.

               (c) Indemnification by Government in Lieu of Insurance. The Indenture Trustee agrees
to accept, in lieu of insurance against any risk with respect to the Aircraft described in Annex B,
indemnification from, or insurance provided by, the U.S. Government, or upon the written consent of
the Indenture Trustee, other Government Entity, against such risk in an amount that, when added to
the amount of insurance (including permitted self-insurance), if any, against such risk that the
Owner (or any Permitted Lessee) may continue to maintain, in accordance with this Section 4.06,
during the period of such requisition or transfer, shall be at least equal to the amount of
insurance against such risk otherwise required by this Section 4.06.

               (d) Application of Insurance Proceeds. As between the Owner and the Indenture
Trustee, all insurance proceeds received as a result of the occurrence of an Event of Loss with
respect to the Aircraft or any Engine under policies required to be maintained by the Owner
pursuant to this Section 4.06 will be applied in accordance with Section 4.05(d). All proceeds of
insurance required to be maintained by the Owner, in accordance with Section 4.06 and Section B of
Annex B, in respect of any property damage or loss not constituting an Event of Loss with respect
to the Aircraft, Airframe or any Engine will be applied in payment (or to reimburse Owner) for
repairs or for replacement property, and any balance remaining after such repairs or replacement
with respect to such damage or loss shall be paid over to, or retained by, the Owner.

          SECTION 4.07. Merger of Owner

               (a) In General. The Owner shall not consolidate with or merge into any other person
under circumstances in which Owner is not the surviving corporation, or convey, transfer or lease
in one or more transactions all or substantially all of its assets to any other person, unless:

                    (i) such person is organized, existing and in good standing under the Laws of the United
States, any State of the United States or the District of Columbia and, upon consummation of such
transaction, such person will be a U.S. Air Carrier;

                    (ii) such person executes and delivers to the Indenture Trustee a duly authorized, legal,
valid, binding and enforceable agreement, reasonably satisfactory in form and substance to the
Indenture Trustee, containing an effective assumption by such person of the due and punctual
performance and observance of each covenant, agreement and condition in the Operative Agreements to
be performed or observed by the Owner;

                    (iii) if the Aircraft is, at the time, registered with the FAA, such person makes such filings
and recordings with the FAA pursuant to the Act or if the Aircraft is, at the time, not registered
with FAA, such person makes such filings and recordings with the applicable Aviation Authority and,
irrespective of the registry of the Aircraft, such person makes

42

 

such registrations with the International Registry, in any case, as shall be necessary to
evidence such consolidation or merger; and

                    (iv) immediately after giving effect to such consolidation or merger no Event of Default shall
have occurred and be continuing.

               (b) Effect of Merger. Upon any such consolidation or merger of the Owner with or
into, or the conveyance, transfer or lease by the Owner of all or substantially all of its assets
to, any Person in accordance with this Section 4.07, such Person will succeed to, and be
substituted for, and may exercise every right and power of, the Owner under the Operative
Agreements with the same effect as if such person had been named as “Owner” therein. No such
consolidation or merger, or conveyance, transfer or lease, shall have the effect of releasing Owner
or such Person from any of the obligations, liabilities, covenants or undertakings of the Owner
under this Trust Indenture.

Trustee of the failure to make such payment when due;

                    (ii) Owner shall fail to carry and maintain, or cause to be carried and maintained, insurance

                    (iii) Owner shall fail to observe or perform (or caused to be observed and performed) in any
material respect any other covenant, agreement or obligation set forth herein or in any other
Operative Agreement to which Owner is a party and such failure shall continue unremedied for a
period of thirty (30) days from and after the date of written notice thereof to the Owner from the
Indenture Trustee, unless such failure is capable of being corrected and the Owner shall be
diligently proceeding to correct such failure, in which case there shall be no Event of Default
unless and until such failure shall continue unremedied for a period of two hundred and seventy
(270) days after receipt of such notice;

43

 

                    (iv) any representation or warranty made by the Owner herein, in the Participation Agreement
or in any other Operative Agreement to which Owner is a party (a) shall prove to have been untrue
or inaccurate in any material respect as of the date made, (b) such untrue or inaccurate
representation or warranty is material at the time in question, (c) and the same shall remain
uncured (to the extent of the adverse impact of such incorrectness on the interest of the Indenture
Trustee) for a period in excess of thirty (30) days from and after the date of written notice
thereof from the Indenture Trustee to the Owner;

                    (v) the Owner shall consent to the appointment of or taking possession by a receiver, trustee
or liquidator of itself or of a substantial part of its property, or the Owner shall admit in
writing its inability to pay its debts generally as they come due or shall make a general
assignment for the benefit of its creditors, or the Owner shall file a voluntary petition in
bankruptcy or a voluntary petition or an answer seeking reorganization, liquidation or other relief
under any bankruptcy laws or insolvency laws (as in effect at such time), or an answer admitting
the material allegations of a petition filed against it in any such case, or the Owner shall seek
relief by voluntary petition, answer or consent, under the provisions of any other bankruptcy or
similar law providing for the reorganization or winding-up of corporations (as in effect at such
time), or the Owner shall seek an agreement, composition, extension or adjustment with its
creditors under such laws;

                    (vi) an order, judgment or decree shall be entered by any court of competent jurisdiction
appointing, without the consent of the Owner, a receiver, trustee or liquidator of the Owner or of
any substantial part of its property, or any substantial part of the property of the Owner shall be
sequestered, or granting any other relief in respect of the Owner as a debtor under any bankruptcy
laws or other insolvency laws (as in effect at such time), and any such order, judgment, decree, or
decree of appointment or sequestration shall remain in force undismissed, unstayed or unvacated for
a period of ninety (90) consecutive days after the date of entry thereof;

                    (vii) a petition against the Owner in a proceeding under any bankruptcy laws or other
insolvency laws (as in effect at such time) is filed and not withdrawn or dismissed within 90 days
thereafter, or if, under the provisions of any law providing for reorganization or winding-up of
corporations which may apply to the Owner, any court of competent jurisdiction shall assume
jurisdiction, custody or control of the Owner of any substantial part of its property and such

a period of ninety (90) consecutive days; or

                    (viii) the occurrence of a Related Indenture Event of Default.

provided, however, that, notwithstanding anything to the contrary contained in this
Section 5.01, any failure of Owner to perform or observe any covenant, condition, agreement or any
error in a representation or warranty shall not constitute an Event of Default if such failure or
error is caused solely by reason of any event that constitutes an Event of Loss so long as Owner is
continuing to comply with all of the terms of Section 4.04(e) and Section 4.05 hereof.

44

 

          SECTION 5.02. 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 Indenture Trustee may exercise any or all of
the rights and powers and pursue any and all of the remedies pursuant to this Article V and shall
have and may exercise all of the rights and remedies of a secured party under the Uniform
Commercial Code or of a chargee under the Cape Town Treaty 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 exclude the Owner and all persons claiming under it wholly or partly therefrom;
provided that the Indenture Trustee shall give the Owner twenty (20) days’ prior written
notice of its intention to sell the Aircraft; provided further, that during any period the
Aircraft is subject to the CRAF program and in possession of the U.S. Government or an agency or
instrumentality of the United States, the Indenture Trustee shall not, on account of any Event of
Default, be entitled to exercise or pursue any of the powers, rights or remedies described in this
Article V in such manner as to limit the Owner’s control (or any Permitted Lessee’s control under
any lease) of any Airframe or any Engines installed thereon, unless at least sixty (60) days (or
such lesser period as may then be applicable under the Air Mobility Command program of the U.S.
Government) written notice of default hereunder shall have been given by the Indenture Trustee by
registered or certified mail to the Owner (any Permitted Lessee) with a copy addressed to the
Contracting Office Representative of the Air Mobility Command of the United States Air Force under
any contract with the Owner (or any Permitted Lessee) relating to the Aircraft. Without limiting
any of the foregoing, it is understood and agreed that the Indenture Trustee may exercise any right
of sale of the Aircraft available to it, even though it shall not have taken possession of the
Aircraft and shall not have possession thereof at the time of such sale.

               (b) If an Event of Default shall have occurred and be continuing, then and in every such case
the Indenture Trustee may (and shall, upon receipt of a written demand therefor from a Majority in
Interest of Note Holders), at any time, by delivery of written notice or notices to the Owner,
declare all the Equipment Notes to be due and payable, whereupon the unpaid Original Amount of all
Equipment Notes then outstanding, together with accrued but unpaid interest thereon (without
Make-Whole Amount) and other amounts due thereunder or otherwise payable hereunder, shall
immediately become due and payable without presentment, demand, protest or notice, all of which are
hereby waived; provided that if an Event of Default referred to in clause (v), (vi) or (vii) of
Section 5.01 hereof shall have occurred, then and in every such case the unpaid Original Amount
then outstanding, together with accrued but unpaid interest (without Make-Whole Amount) and all
other amounts due hereunder and under the Equipment Notes shall immediately and without further act
become due and payable without presentment, demand, protest or notice, all of which are hereby
waived.

          This Section 5.02(b), however, is subject to the condition that, if at any time after the
Original Amount of the Equipment Notes shall have become so due and payable, and before any
judgment or decree for the payment of the money so due, or any thereof, shall be entered, all
overdue payments of interest upon the Equipment Notes and all other amounts payable hereunder or
under the Equipment Notes (except the Original Amount of the Equipment Notes and any Make-Whole
Amount which by such declaration shall have become payable) shall have

45

 

been duly paid, and every other Default and Event of Default with respect to any covenant or
provision of this Trust Indenture shall have been cured, then and in every such case a Majority in
Interest of Note Holders may (but shall not be obligated to), by written instrument filed with the
Indenture Trustee, rescind and annul the Indenture Trustee’s declaration (or such automatic
acceleration) and its consequences; but no such rescission or annulment shall extend to or affect
any subsequent Default or Event of Default or impair any right consequent thereon.

               (c) The Note Holders shall be entitled, at any sale pursuant to this Section 5.02, to credit
against any purchase price bid at such sale by such holder all or any part of the unpaid
obligations owing to such Note Holder and secured by the Lien of this Trust Indenture (only to the
extent that such purchase price would have been paid to such Note Holder pursuant to Article III
hereof if such purchase price were paid in cash and the foregoing provisions of this subsection (c)
were not given effect).

               (d) 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
Trust Indenture, the unpaid Original Amount of all Equipment Notes then outstanding, together with
accrued interest thereon (without Make-Whole Amount), and other amounts due thereunder, shall
immediately become due and payable without presentment, demand, protest or notice, all of which are
hereby waived.

               (e) Notwithstanding anything contained herein, so long as the Pass Through Trustee under any
Pass Through Trust Agreement (or its designee) is a Note Holder, the Indenture Trustee will not be
authorized or empowered to acquire title to any Collateral or take any action with respect to any
Collateral so acquired by it if such acquisition or action would cause any Trust to fail to qualify
as a “grantor trust” for federal income tax purposes.

          SECTION 5.03. Return of Aircraft, Etc.

               (a) If an Event of Default shall have occurred and be continuing and the Equipment Notes have
been accelerated, at the request of the Indenture Trustee, the Owner shall promptly execute and
deliver to the Indenture Trustee such instruments of title and other documents as the Indenture
Trustee may deem necessary or advisable to enable the Indenture Trustee or an agent or
representative designated by the Indenture Trustee, at such time or times and place or places as
the Indenture Trustee may specify, to obtain possession of all or any part of the Collateral to
which the Indenture Trustee shall at the time be entitled hereunder. If the Owner shall for any
reason fail to execute and deliver such instruments and documents after such request by the
Indenture Trustee, the Indenture Trustee may (i) obtain a judgment conferring on the Indenture
Trustee the right to immediate possession and requiring the Owner to execute and deliver such
instruments and documents to the Indenture Trustee, to the entry of which judgment the Owner 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 the Owner wherever such
Collateral may be or be 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 Trust Indenture.

46

 

               (b) Upon every such taking of possession, the Indenture Trustee 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 Indenture Trustee 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 the Owner relating to the Collateral, as the
Indenture Trustee 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 Indenture
Trustee may determine, and the Indenture Trustee 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 Indenture Trustee under any provision of this Trust Indenture to
collect and receive all cash held by, or required to be deposited with, the Indenture Trustee
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 Indenture Trustee 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 Owner), and all other payments which the Indenture
Trustee may be required or authorized to make under any provision of this Trust Indenture, as well
as just and reasonable compensation for the services of the Indenture Trustee, and of all persons
properly engaged and employed by the Indenture Trustee with respect hereto.

          SECTION 5.04. Remedies Cumulative

          Each and every right, power and remedy given to the Indenture Trustee specifically or
otherwise in this Trust Indenture 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 Indenture Trustee, 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. No delay or omission by the Indenture Trustee 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 Owner or to
be an acquiescence therein.

          SECTION 5.05. Discontinuance of Proceedings

          In case the Indenture Trustee shall have instituted any proceeding to enforce any right, power
or remedy under this Trust Indenture 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
Indenture Trustee, then and in every such case the Owner and the Indenture Trustee shall, subject
to any determination in such proceedings, be restored to their

47

 

former positions and rights hereunder with respect to the Collateral, and all rights, remedies
and powers of the Owner or the Indenture Trustee shall continue as if no such proceedings had been
instituted.

          SECTION 5.06. Waiver of Past Defaults

          Upon written instruction from a Majority in Interest of Note Holders, the Indenture Trustee
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 Trust Indenture, 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 Note Holders, the Indenture Trustee shall not waive any Default (i) in
the payment of the Original Amount, Make-Whole Amount, if any, and interest and other amounts due
under any Equipment Note then outstanding, or (ii) in respect of a covenant or provision hereof
which, under Article X hereof, cannot be modified or amended without the consent of each Note
Holder.

          SECTION 5.07. Appointment of Receiver

          If an Event of Default shall have occurred and be continuing, the Indenture Trustee shall, as
a matter of right, be entitled to the appointment of a receiver (who may be the Indenture Trustee
or any successor or nominee thereof) for all or any part of the Collateral, whether such
receivership be incidental to a proposed sale of the Collateral or the taking of possession thereof
or otherwise, and the Owner 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 Indenture Trustee with respect to the
Collateral.

          SECTION 5.08. Indenture Trustee Authorized to Execute Bills of Sale, Etc.

          The Owner irrevocably appoints, while an Event of Default has occurred and is continuing, the
Indenture Trustee the true and lawful attorney-in-fact of the Owner (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 Trust Indenture,
whether pursuant to foreclosure or power of sale, assignments and other instruments as may be
necessary or appropriate, with full power of substitution, the Owner 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 Indenture Trustee or any purchaser, the Owner
shall ratify and confirm any such sale, assignment, transfer or delivery, by executing and
delivering to the Indenture Trustee 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 5.09. Rights of Note Holders to Receive Payment

          Notwithstanding any other provision of this Trust Indenture, the right of any Note Holder to
receive payment of principal of, and premium, if any, and interest on an Equipment

48

 

Note on or after the respective due dates expressed in such Equipment Note, or to bring suit
for the enforcement of any such payment on or after such respective dates in accordance with the
terms hereof, shall not be impaired or affected without the consent of such Note Holder.

ARTICLE VI

DUTIES OF THE INDENTURE TRUSTEE

          SECTION 6.01. Notice of Event of Default

          If the Indenture Trustee shall have Actual Knowledge of an Event of Default or of a Default
arising from a failure to pay any installment of principal and interest on any Equipment Note, the
Indenture Trustee shall give prompt written notice thereof to each Note Holder. Subject to the
terms of Sections 5.06, 6.02 and 6.03 hereof, the Indenture Trustee shall take such action, or
refrain from taking such action, with respect to such Event of Default or Default (including with
respect to the exercise of any rights or remedies hereunder) as the Indenture Trustee shall be
instructed in writing by a Majority in Interest of Note Holders. Subject to the provisions of
Section 6.03, if the Indenture Trustee shall not have received instructions as above provided
within 20 days after mailing notice of such Event of Default to the Note Holders, the Indenture
Trustee may, subject to instructions thereafter received pursuant to the preceding provisions of
this Section 6.01, take such action, or refrain from taking such action, but shall be under no duty
to take or refrain from taking any action, with respect to such Event of Default or Default as it
shall determine advisable in the best interests of the Note Holders; provided,
however, that the Indenture Trustee may not sell the Aircraft or any Engine without the
consent of a Majority in Interest of Note Holders. For all purposes of this Trust Indenture, in
the absence of Actual Knowledge on the part of the Indenture Trustee, the Indenture Trustee shall
not be deemed to have knowledge of a Default or an Event of Default (except, the failure of the
Owner to pay any installment of principal or interest within one Business Day after the same shall
become due, which failure shall constitute knowledge of a Default) unless notified in writing by
the Owner or one or more Note Holders.

          SECTION 6.02. Action Upon Instructions; Certain Rights and Limitations

          Subject to the terms of Sections 5.02(a), 5.06, 6.01 and 6.03 hereof, upon the written
instructions at any time and from time to time of a Majority in Interest of Note Holders, the
Indenture Trustee shall, subject to the terms of this Section 6.02, take such of the following
actions as may be specified in such instructions: (i) give such notice or direction or exercise
such right, remedy or power hereunder as shall be specified in such instructions and (ii) give such
notice or direction or exercise such right, remedy or power hereunder with respect to any part of
the Collateral as shall be specified in such instructions; it being understood that without the
written instructions of a Majority in Interest of Note Holders, the Indenture Trustee shall not,
except as provided in Section 6.01, approve any such matter as satisfactory to the Indenture
Trustee.

          The Indenture Trustee will execute and the Owner will file such continuation statements with
respect to financing statements relating to the security interest created hereunder

49

 

in the Collateral as may be specified from time to time in written instructions of a Majority
in Interest of Note Holders (which instructions shall be accompanied by the form of such
continuation statement so to be filed). The Indenture Trustee will furnish to each Note Holder,
promptly upon receipt thereof, duplicates or copies of all reports, notices, requests, demands,
certificates and other instruments furnished to the Indenture Trustee hereunder.

          SECTION 6.03. Indemnification

          The Indenture Trustee shall not be required to take any action or refrain from taking any
action under Section 6.01 (other than the first sentence thereof), 6.02 or Article V hereof unless
the Indenture Trustee shall have been indemnified to its reasonable satisfaction against any
liability, cost or expense (including counsel fees) which may be incurred in connection therewith
pursuant to a written agreement with one or more Note Holders. The Indenture Trustee agrees that
it shall look solely to the Note Holders for the satisfaction of any indemnity (except expenses for
foreclosure of the type referred to in clause “First” of Section 3.03 hereof) owed to it pursuant
to this Section 6.03. The Indenture Trustee shall not be under any obligation to take any action
under this Trust Indenture or any other Operative Agreement and nothing herein or therein shall
require the Indenture Trustee to expend or risk its own funds or otherwise incur the risk of any
financial liability in the performance of any of its rights or powers if it shall have reasonable
grounds for believing that repayment of such funds or adequate indemnity against such risk or
liability is not reasonably assured to it (the written indemnity of any Note Holder who is a QIB,
signed by an authorized officer thereof, in favor of, delivered to and in form reasonably
satisfactory to the Indenture Trustee shall be accepted as reasonable assurance of adequate
indemnity). The Indenture Trustee shall not be required to take any action under Section 6.01
(other than the first sentence thereof) or 6.02 or Article V hereof, nor shall any other provision
of this Trust Indenture or any other Operative Agreement be deemed to impose a duty on the
Indenture Trustee to take any action, if the Indenture Trustee shall have been advised by counsel
that such action is contrary to the terms hereof or is otherwise contrary to Law.

          SECTION 6.04. No Duties Except as Specified in Trust Indenture or Instructions

          The Indenture Trustee shall not have any duty or obligation to use, operate, store, lease,
control, manage, sell, 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,
this Trust Indenture or any part of the Collateral, except as expressly provided by the terms of
this Trust Indenture or as expressly provided in written instructions from Note Holders as provided
in this Trust Indenture; and no implied duties or obligations shall be read into this Trust
Indenture against the Indenture Trustee. The Indenture Trustee agrees that it will in its
individual capacity and at its own cost and expense (but without any right of indemnity in respect
of any such cost or expense under Section 8.01 hereof), promptly take such action as may be
necessary duly to discharge all liens and encumbrances on any part of the Collateral which result
from claims against it in its individual capacity not related to the administration of the
Collateral or any other transaction pursuant to this Trust Indenture or any document included in
the Collateral.

50

 

          SECTION 6.05. No Action Except Under Trust Indenture or Instructions

          The Indenture Trustee will not use, operate, store, lease, control, manage, sell, dispose of
or otherwise deal with the Aircraft or any other part of the Collateral except in accordance with
the powers granted to, or the authority conferred upon the Indenture Trustee pursuant to this Trust
Indenture and in accordance with the express terms hereof.

          SECTION 6.06. Investment of Amounts Held by Indenture Trustee

          Any amounts held by the Indenture Trustee pursuant to Section 3.02, 3.03 or 3.07 or pursuant
to any provision of any other Operative Agreement providing for amounts to be held by the Indenture
Trustee which are not distributed pursuant to the other provisions of Article III hereof shall be
invested by the Indenture Trustee from time to time in Cash Equivalents as directed by the Owner so
long as the Indenture Trustee may acquire the same using its best efforts. All Cash Equivalents
held by the Indenture Trustee pursuant to this Section 6.06 shall either be (a) registered in the
name of, payable to the order of, or specially endorsed to, the Indenture Trustee, or (b) held in
an Eligible Account. Unless otherwise expressly provided in this Trust Indenture, any income
realized as a result of any such investment, net of the Indenture Trustee’s reasonable fees and
expenses in making such investment, shall be held and applied by the Indenture Trustee in the same
manner as the principal amount of such investment is to be applied and any losses, net of earnings
and such reasonable fees and expenses, shall be charged against the principal amount invested. The
Indenture Trustee shall not be liable for any loss resulting from any investment required to be
made by it under this Trust Indenture other than by reason of its willful misconduct or gross
negligence or negligence in the handling of funds, and any such investment may be sold (without
regard to its maturity) by the Indenture Trustee without instructions whenever such sale is
necessary to make a distribution required by this Trust Indenture.

ARTICLE VII

THE INDENTURE TRUSTEE

          SECTION 7.01. Acceptance of Trusts and Duties

          The Indenture Trustee accepts the duties hereby created and applicable to it and agrees to
perform the same but only upon the terms of this Trust Indenture and agrees to receive and disburse
all monies constituting part of the Collateral in accordance with the terms hereof. The Indenture
Trustee, in its individual capacity, shall not be answerable or accountable under any
circumstances, except (i) for its own willful misconduct or gross negligence (other than for the
handling of funds, for which the standard of accountability shall be willful misconduct or
negligence), (ii) as provided in the fourth sentence of Section 2.03(a) hereof and the last
sentence of Section 6.04 hereof, and (iii) from the inaccuracy of any representation or warranty of
the Indenture Trustee (in its individual capacity) in the Participation Agreement or expressly made
hereunder.

51

 

          SECTION 7.02. Absence of Duties

          Except in accordance with written instructions furnished pursuant to Section 6.01 or 6.02
hereof, and except as provided in, and without limiting the generality of, Sections 6.03, 6.04 and
7.07 hereof the Indenture Trustee shall have no duty (i) to see to any registration of the Aircraft
or any recording or filing of this Trust Indenture or any other document, or to see to the
maintenance of any such registration, recording or filing, (ii) to see to any insurance on the
Aircraft or to effect or maintain any such insurance, whether or not the Owner shall be in default
with respect thereto, (iii) to see to the payment or discharge of any lien or encumbrance of any
kind against any part of the Collateral, (iv) to confirm, verify or inquire into the failure to
receive any financial statements from the Owner, or (v) to inspect the Aircraft at any time or
ascertain or inquire as to the performance or observance of any of the Owner’s covenants herein or
any Permitted Lessee’s covenants under any assigned Permitted Lease with respect to the Aircraft.

          SECTION 7.03. No Representations or Warranties as to Aircraft or Documents

          THE INDENTURE TRUSTEE IN ITS INDIVIDUAL OR TRUST CAPACITY DOES NOT MAKE AND SHALL NOT BE
DEEMED TO HAVE MADE AND HEREBY EXPRESSLY DISCLAIMS ANY REPRESENTATION OR WARRANTY, EXPRESS OR
IMPLIED, AS TO THE TITLE, AIRWORTHINESS, VALUE, COMPLIANCE WITH SPECIFICATIONS, CONDITION, DESIGN,
QUALITY, DURABILITY, OPERATION, MERCHANTABILITY OR FITNESS FOR USE FOR A PARTICULAR PURPOSE OF THE
AIRCRAFT OR ANY ENGINE, AS TO THE ABSENCE OF LATENT OR OTHER DEFECTS, WHETHER OR NOT DISCOVERABLE,
AS TO THE ABSENCE OF ANY INFRINGEMENT OF ANY PATENT, TRADEMARK OR COPYRIGHT, AS TO THE ABSENCE OF
OBLIGATIONS BASED ON STRICT LIABILITY IN TORT OR ANY OTHER REPRESENTATION OR WARRANTY WHATSOEVER.
The Indenture Trustee, in its individual or trust capacities, does not make or shall not be deemed
to have made any representation or warranty as to the validity, legality or enforceability of this
Trust Indenture, the Participation Agreement, the Equipment Notes, or as to the correctness of any
statement contained in any thereof, except for the representations and warranties of the Owner made
in its individual capacity and the representations and warranties of the Indenture Trustee in its
individual capacity, in each case expressly made in this Trust Indenture or in the Participation
Agreement. The Note Holders make no representation or warranty hereunder whatsoever.

          SECTION 7.04. No Segregation of Monies; No Interest

          Except as otherwise provided in Section 3.07 hereof, any monies paid to or retained by the
Indenture Trustee pursuant to any provision hereof and not then required to be distributed to the
Note Holders, or the Owner as provided in Article III hereof need not be segregated in any manner
except to the extent required by Law or Section 6.06 hereof, and may be deposited under such
general conditions as may be prescribed by Law, and the Indenture Trustee shall not be liable for
any interest thereon (except that the Indenture Trustee shall invest all monies held as directed by
the Owner so long as no Event of Default has occurred and is continuing (or in the absence of such
direction, by the Majority In Interest of Note Holders) in

52

 

Cash Equivalents); provided, however, that any payments received, or applied
hereunder, by the Indenture Trustee shall be accounted for by the Indenture Trustee so that any
portion thereof paid or applied pursuant hereto shall be identifiable as to the source thereof.

          SECTION 7.05. Reliance; Agreements; Advice of Counsel

          The Indenture Trustee shall not incur any liability to anyone in acting upon any signature,
instrument, notice, resolution, request, consent, order, certificate, report, opinion, bond or
other document or paper believed by it to be genuine and believed by it to be signed by the proper
party or parties. The Indenture Trustee may accept a copy of a resolution of the Board of
Directors of the Owner, certified by the Secretary or an Assistant Secretary thereof as duly
adopted and in full force and effect, as conclusive evidence that such resolution has been duly
adopted and that the same is in full force and effect. As to the aggregate unpaid Original Amount
of Equipment Notes outstanding as of any date, the Owner may for all purposes hereof rely on a
certificate signed by any Vice President or other authorized corporate trust officer of the
Indenture Trustee. As to any fact or matter relating to the Owner the manner of the ascertainment
of which is not specifically described herein, the Indenture Trustee may for all purposes hereof
rely on a certificate, signed by a duly authorized officer of the Owner, as to such fact or matter,
and such certificate shall constitute full protection to the Indenture Trustee for any action taken
or omitted to be taken by it in good faith in reliance thereon. In the administration of the
trusts hereunder, the Indenture Trustee may execute any of the trusts or powers hereof and perform
its powers and duties hereunder directly or through agents or attorneys and may, at the expense of
the Collateral, advise with counsel, accountants and other skilled persons to be selected and
retained by it, and the Indenture Trustee shall not be liable for anything done, suffered or
omitted in good faith by it in accordance with the written advice or written opinion of any such
counsel, accountants or other skilled persons.

          SECTION 7.06. Compensation

          The Indenture Trustee shall be entitled to reasonable compensation, including expenses and
disbursements (including the reasonable fees and expenses of counsel), for all services rendered
hereunder and shall, on and subsequent to an Event of Default hereunder, have a priority claim on
the Collateral for the payment of such compensation, to the extent that such compensation shall not
be paid by the Owner, and shall have the right, on and subsequent to an Event of Default hereunder,
to use or apply any monies held by it hereunder in the Collateral toward such payments. The
Indenture Trustee agrees that it shall have no right against the Note Holders for any fee as
compensation for its services as trustee under this Trust Indenture.

          SECTION 7.07. Instructions from Note Holders

          In the administration of the trusts created hereunder, the Indenture Trustee shall have the
right to seek instructions from a Majority in Interest of Note Holders should any provision of this
Trust Indenture appear to conflict with any other provision herein or should the Indenture
Trustee’s duties or obligations hereunder be unclear, and the Indenture Trustee shall incur no
liability in refraining from acting until it receives such instructions. The Indenture

53

 

Trustee shall be fully protected for acting in accordance with any instructions received under
this Section 7.07.

ARTICLE VIII

INDEMNIFICATION

          SECTION 8.01. Scope of Indemnification

          The Indenture Trustee shall be indemnified by the Owner to the extent and in the manner
provided in Section 8 of the Participation Agreement.

ARTICLE IX

SUCCESSOR AND SEPARATE TRUSTEES

          SECTION 9.01. Resignation of Indenture Trustee; Appointment of Successor

               (a) The Indenture Trustee or any successor thereto may resign at any time without cause by
giving at least thirty (30) days’ prior written notice to the Owner and each Note Holder, such
resignation to be effective upon the acceptance of the trusteeship by a successor Indenture
Trustee. In addition, a Majority in Interest of Note Holders may at any time (but only with the
consent of the Owner, which consent shall not be unreasonably withheld, except that such consent
shall not be necessary if an Event of Default is continuing) remove the Indenture Trustee without
cause by an instrument in writing delivered to the Owner and the Indenture Trustee, and the
Indenture Trustee shall promptly notify each Note Holder thereof in writing, such removal to be
effective upon the acceptance of the trusteeship by a successor Indenture Trustee. In the case of
the resignation or removal of the Indenture Trustee, a Majority in Interest of Note Holders may
appoint a successor Indenture Trustee by an instrument signed by such holders, which successor, so
long as no Event of Default shall have occurred and be continuing, shall be subject to the Owner’s
reasonable approval. If a successor Indenture Trustee shall not have been appointed within thirty
(30) days after such notice of resignation or removal, the Indenture Trustee, the Owner or any Note
Holder may apply to any court of competent jurisdiction to appoint a successor Indenture Trustee to
act until such time, if any, as a successor shall have been appointed as above provided. The
successor Indenture Trustee so appointed by such court shall immediately and without further act be
superseded by any successor Indenture Trustee appointed as above provided.

               (b) Any successor Indenture Trustee, however appointed, shall execute and deliver to the Owner
and the predecessor Indenture Trustee an instrument accepting such appointment and assuming the
obligations of the Indenture Trustee arising from and after the time of such appointment, and
thereupon such successor Indenture Trustee, without further act, shall become vested with all the
estates, properties, rights, powers and duties of the predecessor Indenture Trustee hereunder in
the trust hereunder applicable to it with like effect as if originally

54

 

named the Indenture Trustee herein; but nevertheless upon the written request of such
successor Indenture Trustee, such predecessor Indenture Trustee shall execute and deliver an
instrument transferring to such successor Indenture Trustee, upon the trusts herein expressed
applicable to it, all the estates, properties, rights and powers of such predecessor Indenture
Trustee, and such predecessor Indenture Trustee shall duly assign, transfer, deliver and pay over
to such successor Indenture Trustee all monies or other property then held by such predecessor
Indenture Trustee hereunder.

               (c) Any successor Indenture Trustee, however appointed, shall be a bank or trust company
having its principal place of business in the Borough of Manhattan, City and State of New York;
Chicago, Illinois; Hartford, Connecticut; Wilmington, Delaware; or Boston, Massachusetts and having
(or whose obligations under the Operative Agreements are guaranteed by an affiliated entity having)
a combined capital and surplus of at least $100,000,000, if there be such an institution willing,
able and legally qualified to perform the duties of the Indenture Trustee hereunder upon reasonable
or customary terms.

               (d) Any corporation into which the Indenture Trustee may be merged or converted or with which
it may be consolidated, or any corporation resulting from any merger, conversion or consolidation
to which the Indenture Trustee shall be a party, or any corporation to which substantially all the
corporate trust business of the Indenture Trustee may be transferred, shall, subject to the terms
of paragraph (c) of this Section 9.01, be a successor Indenture Trustee and the Indenture Trustee
under this Trust Indenture without further act.

               (e) The Owner consents to any change in the identity of the Indenture Trustee on the
International Registry occasioned by provisions of this Section 9.01, and if required by the
International Registry to reflect such change, will provide its consent thereto.

          SECTION 9.02. Appointment of Additional and Separate Trustees

               (a) Whenever (i) the Indenture Trustee shall deem it necessary or desirable in order to
conform to any Law of any jurisdiction in which all or any part of the Collateral shall be situated
or to make any claim or bring any suit with respect to or in connection with the Collateral, this
Trust Indenture, any other Indenture Agreement, the Equipment Notes or any of the transactions
contemplated by the Participation Agreement, (ii) the Indenture Trustee shall be advised by counsel
satisfactory to it that it is so necessary or prudent in the interests of the Note Holders (and the
Indenture Trustee shall so advise the Owner), or (iii) the Indenture Trustee shall have been
requested to do so by a Majority in Interest of Note Holders, then in any such case, the Indenture
Trustee and, upon the written request of the Indenture Trustee, the Owner, shall execute and
deliver an indenture supplemental hereto and such other instruments as may from time to time be
necessary or advisable either (1) to constitute one or more bank or trust companies or one or more
persons approved by the Indenture Trustee, either to act jointly with the Indenture Trustee as
additional trustee or trustees of all or any part of the Collateral, or to act as separate trustee
or trustees of all or any part of the Collateral, in each case with such rights, powers, duties and
obligations consistent with this Trust Indenture as may be provided in such supplemental indenture
or other instruments as the Indenture Trustee or a Majority in Interest of Note Holders may deem
necessary or advisable, or (2) to clarify, add to

55

 

or subtract from the rights, powers, duties and obligations theretofore granted any such
additional or separate trustee, subject in each case to the remaining provisions of this Section
9.02. If the Owner shall not have taken any action requested of it under this Section 9.02(a) that
is permitted or required by its terms within 15 days after the receipt of a written request from
the Indenture Trustee so to do, or if an Event of Default shall have occurred and be continuing,
the Indenture Trustee may act under the foregoing provisions of this Section 9.02(a) without the
concurrence of the Owner, and the Owner hereby irrevocably appoints (which appointment is coupled
with an interest) the Indenture Trustee, its agent and attorney-in-fact to act for it under the
foregoing provisions of this Section 9.02(a) in either of such contingencies. The Indenture
Trustee may, in such capacity, execute, deliver and perform any such supplemental indenture, or any
such instrument, as may be required for the appointment of any such additional or separate trustee
or for the clarification of, addition to or subtraction from the rights, powers, duties or
obligations theretofore granted to any such additional or separate trustee. In case any additional
or separate trustee appointed under this Section 9.02(a) shall die, become incapable of acting,
resign or be moved, all the assets, property, rights, powers, trusts, duties and obligations of
such additional or separate trustee shall revert to the Indenture Trustee until a successor
additional or separate trustee is appointed as provided in this Section 9.02(a).

               (b) No additional or separate trustee shall be entitled to exercise any of the rights, powers,
duties and obligations conferred upon the Indenture Trustee in respect of the custody, investment
and payment of monies and all monies received by any such additional or separate trustee from or
constituting part of the Collateral or otherwise payable under any Operative Agreement to the
Indenture Trustee shall be promptly paid over by it to the Indenture Trustee. All other rights,
powers, duties and obligations conferred or imposed upon any additional or separate trustee shall
be exercised or performed by the Indenture Trustee and such additional or separate trustee jointly
except to the extent that applicable Law of any jurisdiction in which any particular act is to be
performed renders the Indenture Trustee incompetent or unqualified to perform such act, in which
event such rights, powers, duties and obligations (including the holding of title to all or part of
the Collateral in any such jurisdiction) shall be exercised and performed by such additional or
separate trustee. No additional or separate trustee shall take any discretionary action except on
the instructions of the Indenture Trustee or a Majority in Interest of Note Holders. No trustee
hereunder shall be personally liable by reason of any act or omission of any other trustee
hereunder, except that the Indenture Trustee shall be liable for the consequences of its lack of
reasonable care in selecting, and the Indenture Trustee’s own actions in acting with, any
additional or separate trustee. Each additional or separate trustee appointed pursuant to this
Section 9.02 shall be subject to, and shall have the benefit of Articles V through IX and Article
XI hereof insofar as they apply to the Indenture Trustee. The powers of any additional or separate
trustee appointed pursuant to this Section 9.02 shall not in any case exceed those of the Indenture
Trustee hereunder.

               (c) If at any time the Indenture Trustee shall deem it no longer necessary or in order to
conform to any such Law or take any such action or shall be advised by such counsel that it is no
longer so necessary or desirable in the interest of the Note Holders, or in the event that the
Indenture Trustee shall have been requested to do so in writing by a Majority in Interest of Note
Holders, the Indenture Trustee and, upon the written request of the Indenture Trustee, the Owner,
shall execute and deliver an indenture supplemental hereto and all other

56

 

instruments and agreements necessary or proper to remove any additional or separate trustee.
The Indenture Trustee may act on behalf of the Owner under this Section 9.02(c) when and to the
extent it could so act under Section 9.02(a) hereof.

AND OTHER DOCUMENTS

          SECTION 10.01. Instructions of Majority; Limitations

               (a) The Indenture Trustee agrees with the Note Holders that it shall not enter into any
amendment, waiver or modification of, supplement or consent to this Trust Indenture, or any other
Operative Agreement to which it is a party, unless such supplement, amendment, waiver, modification
or consent is consented to in writing by a Majority in Interest of Note Holders, but upon the
written request of a Majority in Interest of Note Holders, the Indenture Trustee shall from time to
time enter into any such supplement or amendment, or execute and deliver any such waiver,

amendment, supplement or modification), to the extent such agreement is required, agreed to by the
Owner and, as may be appropriate, the Airframe Manufacturer or the Engine Manufacturer;
provided, however, that, without the consent of each holder of an affected
Equipment Note then outstanding and the Liquidity Providers, no such amendment, waiver or
modification of the terms of, or consent under, any thereof, shall (i) modify any of the provisions
of this Section 10.01, or of Article II or III or Section 5.01, 5.02(c), 5.02(d), or 6.02 hereof,
the definitions of “Event of Default,” “Default,” “Majority in Interest of Note Holders,”
“Make-Whole Amount” or “Note Holder,” or the percentage of Note Holders required to take or approve
any action hereunder, (ii) reduce the amount, or change the time of payment or method of
calculation of any amount, of Original Amount, Make-Whole Amount, if any, or interest with respect
to any Equipment Note, (iii) reduce, modify or amend any indemnities in favor of the Indenture
Trustee or the Note Holders (except that the Indenture Trustee may consent to any waiver or
reduction of an indemnity payable to it), or the other Indenture Indemnitees or (iv) permit the

ANNEX B - INSURANCE

TRUST INDENTURE [     ]

ANNEX B

INSURANCE

     Capitalized terms used but not defined herein shall have the respective meanings set forth or
incorporated by reference in Annex A to the Trust Indenture.

A. Liability Insurance

     1. Except as provided in Section A.2 below, and subject to the self-insurance permitted by
Section G below, the Owner will carry or cause to be carried at all times, at no expense to the
Indenture Trustee, comprehensive airline legal liability (including, but not limited to passenger
liability, property damage, baggage liability, cargo and mail liability, hangarkeeper’s liability
and contractual liability insurance) with respect to the Aircraft, the Airframe and the Engines,
which is (i) in an amount not less than the greater of (x) the amount of comprehensive airline
legal liability insurance from time to time applicable to aircraft owned or leased and operated by
the Owner of the same type and operating on similar routes as the Aircraft and (y) the Minimum
Liability Insurance Amount per occurrence; (ii) of the type and covering the same risks as from
time to time applicable to aircraft operated by the Owner of the same type as the Aircraft; and
(iii) maintained in effect with insurers of nationally or internationally recognized responsibility
(such insurers being referred to herein as “Approved Insurers”); provided, however, that
the Owner need not maintain such cargo liability insurance, or may maintain such cargo liability
insurance in an amount less than the Minimum Liability Insurance Amount per occurrence, so long as
the amount of cargo liability insurance, if any, maintained with respect to the Aircraft is not
less than the cargo liability insurance, if any, maintained for other Airbus model [_________]
aircraft owned or leased and operated by the Owner

     2. During any period that the Aircraft is on the ground and not in operation, the Owner may
carry or cause to be carried, in lieu of the insurance required by Section A.1 above, and subject
to the self insurance permitted by Section G below, insurance otherwise conforming with the
provisions of said Section A.1 except that (i) the amounts of coverage shall not be required to
exceed the amounts of public liability and property damage insurance from time to time applicable
to aircraft owned or operated by the Owner of the same type as the Aircraft which are 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 aircraft owned or operated by the Owner of the
same type which are on the ground and not in operation.

B. Hull Insurance

     1. Except as provided in Section B.2 below and subject to the self-insurance permitted by
Section G below, the Owner will carry or cause to be carried at all times, at no expense to the
Indenture Trustee, with Approved Insurers “all-risk” ground and flight aircraft hull insurance
covering each Aircraft (including the Engines when they are installed on the Airframe or any other
airframe) which is of the type as from time to time applicable to aircraft owned by the Owner of
the same type as the Aircraft for an amount denominated in United

 

 

States Dollars not less than the unpaid Original Amount together with six months of interest
accrued thereon (collectively, the “Debt Balance”).

     Any policies of insurance carried in accordance with this Section B.1 or Section C covering
the Aircraft and any policies taken out in substitution or replacement for any such policies (i)
shall name Indenture Trustee as exclusive loss payee for any proceeds to be paid under such
policies in excess of the Threshold Amount, if applicable up to an amount equal to the Debt Balance
and (ii) shall provide that (A) in the event of a loss involving proceeds in excess of the
Threshold Amount, the proceeds in respect of such loss up to an amount equal to the Debt Balance
shall be payable to the Indenture Trustee, except in the case of a loss with respect to an Engine
installed on an airframe other than the Airframe, in which case the Owner (or any 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 Indenture Trustee whether such payment is made to the Owner (or any
Permitted Lessee) or any third party, it being understood and agreed that in the case of any
payment to the Indenture Trustee otherwise than in respect of an Event of Loss, the Indenture
Trustee shall, upon receipt of evidence satisfactory to it 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 the Owner or its order, and (B) the entire
amount of any loss involving proceeds of the Threshold Amount or less or the amount of any proceeds
of any loss in excess of the Debt Balance shall be paid to the Owner or its order unless an Event
of Default shall have occurred and be continuing and the insurers have been notified thereof by the
Indenture Trustee. In the case of a loss with respect to an engine (other than an Engine)
installed on the Airframe, the Indenture Trustee shall hold any payment to it of any insurance
proceeds in respect of such loss for the account of the Owner or any other third party that is
entitled to receive such proceeds.

     2. During any period that the Aircraft is on the ground and not in operation, the Owner may
carry or cause to be carried, subject to the self-insurance permitted by Section G below, in lieu
of the insurance required by Section B.1 above, insurance otherwise conforming with the provisions
of said Section B.1 except that the scope of the risks and the type of insurance shall be the same
as from time to time applicable to aircraft owned by the Owner of the same type similarly on the
ground and not in operation, provided that the Owner shall maintain insurance against risk
of loss or damage to the Aircraft in an amount equal to the Debt Balance during such period that
the Aircraft is on the ground and not in operation.

C. War-Risk, Hijacking and Allied Perils Insurance

     If the Owner (or any Permitted Lessee) shall at any time operate or propose to operate the
Aircraft, Airframe or any Engine (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 any
Permitted Lessee) with respect to other aircraft owned or operated by the Owner (or any Permitted
Lessee) on such routes or in such areas, the Owner 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 aircraft on
similar routes or in such areas and in no event in an amount less than the unpaid Original Amount.

D. General Provisions

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

     (i) in the case of Section A, shall name Indenture Trustee, each Note Holder, each
Related Indenture Trustee, each Related Note Holder and each Liquidity Provider as an
additional insured (collectively, the “Additional Insureds”), as its interests may appear;

     (ii) shall apply worldwide and have no territorial restrictions or limitations (except
only in the case of war, hijacking and related perils insurance required under Section C,
which shall apply to the fullest extent available in the international insurance market);

     (iii) 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 the Owner (or any Permitted Lessee) or
any other Person (including, without limitation, use for illegal purposes of the Aircraft or
any Engine) 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 the Owner (or any Permitted Lessee);

     (iv) 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 thirty (30) (ten (10) days in the event of cancellation due to
non-payment of premium and seven (7) days in the case of war risk, hijacking and allied
perils insurance) days after issuance 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;

     (v) shall waive any rights of setoff (including for unpaid premiums), recoupment,
counterclaim or other deduction, whether by attachment or otherwise, against each Additional
Insured;

     (vi) shall waive any right of recourse or subrogation against any Additional Insured;

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

     (viii) 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;

3

 

     (ix) with respect to hull insurance and war risk, hijacking and allied perils
insurance, shall provide that (a) in the event of a loss involving proceeds in excess of the
Threshold Amount, the proceeds in respect of such loss up to an amount equal to the amount
payable upon the occurrence of an Event of Loss shall be payable to the Indenture Trustee
(so long as the Trust Indenture shall not have been discharged) in the manner set forth in
Sections 2.09 and 2.11 (except in the case of a loss with respect to an Engine installed on
an airframe other than the Airframe, in which case the Owner (or any Permitted Lessee) shall
arrange for any payment of insurance proceeds in respect of such loss to be held for the
account of the Indenture Trustee (so long as the Trust Indenture shall not have been
discharged) whether such payment is made to Owner (or any Lessee) or any third party), it
being understood and agreed that in the case of any payment to the Indenture Trustee
otherwise than in respect of an Event of Loss, the Indenture Trustee shall, upon receipt of
evidence satisfactory to it 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 (and all earnings, if any, thereon) to the Owner or its order,
and (ii) the entire amount of any loss involving proceeds of the Threshold Amount or less or
the amount of any proceeds of any loss in excess of the amount payable upon the occurrence
of an Event of Loss pursuant to Section 4.05(a) shall be paid to Owner or its order unless

notified thereof by the Indenture Trustee;

insurance premium; and

     (xi) shall contain a 50/50% Clause per Lloyd’s Aviation Underwriters’ Association
Standard Policy Form AVS 103.

E. Reports and Certificates; Other Information

     On or prior to the Closing Date and on or prior to each renewal date of the insurance policies
required hereunder, the Owner will furnish or cause to be furnished to the Indenture Trustee
insurance certificates describing in reasonable detail the insurance maintained by the Owner
hereunder and a report, signed by the Owner’s regularly retained independent insurance broker (the
“Insurance Broker”), stating the opinion of such Insurance Broker that (a) all premiums in
connection with the insurance then due have been paid and (b) such insurance complies with the
terms of this Annex B, except that such opinion shall not be required with respect to war risk
insurance provided by the FAA. To the extent such agreement is reasonably obtainable Owner will
also cause the Insurance Broker to agree to advise Indenture Trustee in writing of any default in
the payment of any premium due and to advise Indenture Trustee promptly in writing (seven days in
the case of war-risk and allied perils coverage or such shorter period as may be available in the
international insurance market, as the case may be, if applicable) prior to the cancellation, lapse
or material adverse change of any insurance maintained pursuant to this Annex B.

4

 

F. Right to Pay Premiums

     The Additional Insureds shall have the rights but not the obligations of an additional named
insured. None of the Indenture Trustee and the other Additional Insured 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 Indenture Trustee shall have the option, in its sole discretion, to
pay any such premium in respect of the Aircraft that is due in respect of the coverage pursuant to
the Trust Indenture and to maintain such coverage, as the Indenture Trustee may require, until the
scheduled expiry date of such insurance and, in such event, the Owner shall, upon demand, reimburse
Indenture Trustee for amounts so paid by them.

G. Deductibles; Self-insurance

     The Owner may self-insure by way of deductible, premium adjustment or franchise provisions or
otherwise (including, with respect to insurance maintained pursuant to Section B, insuring for a
maximum amount which is less than the Debt Balance) in the insurance covering the risks required to
be insured against pursuant to Section 4.06 and this Annex B under a program applicable to all
aircraft in the Owner’s fleet, but in no case shall the aggregate amount of self-insurance in
regard to Section 11 and this Annex B exceed during any policy year, with respect to all of the
aircraft in the Owner’s fleet (including, without limitation, the Aircraft), the lesser of (a) 50%
of the largest replacement value of any single aircraft in the Owner’s fleet and (b) 1-1/2% of the
average aggregate insurable value (during the preceding policy year) of all aircraft (including,
without limitation, the Aircraft) on which the Owner carries insurance, unless an insurance broker
of national standing shall certify that the standard among all other major U.S. airlines is a
higher level of self-insurance, in which case the Owner may self-insure to such higher level. In
addition, the Owner (and any Permitted Lessee) may self-insure to the extent of any applicable
deductible per aircraft that does not exceed industry standards for major U.S. airlines.
