                          SALE AND LEASING TRANSACTIONS

          Section 2.01. PARTICIPATION. Subject to all of the terms and
conditions of this Agreement, the parties agree to participate in the sale and
leasing transactions with respect to the Aircraft provided for in this
Article 2.

          (a) SALE AND PURCHASE. The Owner Trustee agrees to purchase the
Aircraft from the Seller on the Delivery Date for a purchase price equal to
Lessor's Cost pursuant to the Aircraft Purchase Agreement.

                                        2
<Page>

          (b) LEASING. The Owner Trustee agrees to lease to the Lessee, and the
Lessee agrees to lease from the Owner Trustee, the Aircraft pursuant to the
Lease, such leasing to take place concurrently with the purchase of the Aircraft
by the Owner Trustee on the Delivery Date.

          (c) OWNER PARTICIPANT'S EQUITY INVESTMENT. The Owner Participant
agrees to provide immediately available funds in an amount equal to the Lessor's
Cost (the "Commitment") (i) by paying such amount to the Owner Trustee prior to
the time of closing on the Delivery Date at the account specified by the Owner
Trustee on or prior to the Delivery Date, such amount to be held and applied
toward the Owner Trustee's payment of Lessor's Cost for the Aircraft on the
Delivery Date (and if not so applied, to be promptly returned to the Owner
Participant) or (ii) by paying such amount at the time of the closing on the
Delivery Date directly to the Seller's account specified by the Seller prior to
the closing to be applied toward the payment of Lessor's Cost. Such funds, once
so applied, shall constitute an equity investment by the Owner Participant in
the Trust Estate.

          (d) DELIVERY DATE. The "Delivery Date" shall be the date fixed by
the Lessee in accordance with this Section 2.01(d) for the closing of the
sale and leasing transactions with respect to the Aircraft contemplated
hereby, except that following such closing the "Delivery Date" shall mean the
date on which such transactions actually closed. The Lessee shall give at
least two Business Days' notice to each other party hereto of the Delivery
Date, which notice shall also specify the amount of the Commitment. The
Lessee may postpone a scheduled Delivery Date from time to time, for any
reason by notice given to the other parties hereto not later than 2:00 p.m.
on the date last scheduled as the Delivery Date, such notice to specify a new
Delivery Date. In the event that the Owner Participant shall have provided
the amount of the Commitment to the Owner Trustee prior to such a
postponement, the Owner Trustee shall return such amount to the Owner
Participant by 2:00 p.m. on the scheduled Delivery Date unless the Owner
Participant shall have agreed otherwise in writing. Absent such an agreement,
in the event that the Commitment is not returned to the Owner Participant by
2:00 p.m. on a scheduled Delivery Date on which the closing does not occur,
the Lessee shall pay interest to the Owner Participant at a rate equal to the
rate per annum announced from time to time by Citibank, N.A. as its prime
rate plus [*] for each day that such commitment is not returned to the Owner
Participant by 2:00 p.m.. The making available by the Owner Participant of
the Commitment at the closing shall be deemed a waiver of notice of the
Delivery Date by the Owner Participant and the Owner Trustee.

          Section 2.02. CLOSING PROCEDURE.

          (a) TIME AND PLACE. The closing shall take place at 11:00 a.m. New
York City local time on the Delivery Date at the offices of Fulbright & Jaworski
L.L.P., 666 Fifth Avenue, New York, New York or at such other time and place as
the parties may agree. The closing shall be preceded by a pre-closing at the

of the Operative Agreements to be executed, the certificates and other documents
to be delivered and the forms of the legal opinions to be delivered at the
closing by each party or its counsel pursuant to this Agreement shall be

     delivery of any document or instrument and the payment of any sum necessary
     or, by reference to prudent industry practice in such country, advisable in
     order to create, preserve and protect such interest in the Aircraft as

     such Person;

               (x) any export licenses and certificate of deregistration

     onerous than under the laws of the United States or any state thereof (it
     being agreed that, in the event such opinion cannot be given in a form
     satisfactory to the Owner Participant, such opinion shall be waived if

               (xii) unless Lessee shall have agreed to provide insurance
     reasonably satisfactory to the Owner Participant covering the risk of
     requisition of use of or title to 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 Lessee prior to such proposed reregistration has obtained such
     license or permit or such license or permit will be readily obtainable in

     respect the choice of New York law to govern the Lease;

               (xiv) such re-registration may not be effected until after the
     Recovery Period unless the Lessee prepays on a lump sum basis any liability

     under the Lease), (vii), (ix), (x), (xi), (xii) and (xiii) of this
     Section 4.02(b);

               (xvi) such proposed change in registration is made in connection
     with a Sublease to a Permitted Air Carrier and such Permitted Sublessee is
     domiciled in such country; and

          (d) CORPORATE EXISTENCE. The Lessee shall at all times maintain its
corporate existence, except as permitted by Section 4.02(e) hereof, and all of
its rights, privileges and franchises necessary in the normal conduct of its
business, except for any corporate right, privilege or franchise that it
determines is no longer necessary or desirable in the conduct of its business.

          (e) MERGER AND CONSOLIDATION. The Lessee shall not, during the Term,
enter into any merger with or into or consolidation with, or sell, convey,
transfer, lease or otherwise dispose of in one or a series of transactions all
or substantially all of its assets as an entirety to any Person, unless the
surviving corporation or Person which acquires by purchase, conveyance, transfer
or lease all or substantially all of the assets of the Lessee as an entirety (i)
is a domestic corporation organized and existing under the laws of the United
States or any State of the United States, (ii) is a Citizen of the United
States, (iii) is a Section 1110 Person, so long as such status is a condition to
the availability of Section 1110, (iv) if not the Lessee, executes a duly
authorized, legal, valid, binding, and enforceable agreement, reasonably
satisfactory in form and substance to Owner Trustee and Owner Participant,
containing an effective assumption of all of the Lessee's, as applicable,

merger, consolidation, conveyance, transfer, lease or other disposition and the
instrument noted in clause (iv) above comply with this Section 4.02(e), that
such instrument is a legal, valid and binding obligation of, and is enforceable
against, such survivor or Person, and that all conditions precedent herein
provided for relating to such transaction have been complied with, and (vi) such
survivor or Person makes such filings and recordings with the FAA as may be
required pursuant to part A of subtitle VII of Title 49, United States Code to
evidence such merger or consolidation; PROVIDED THAT, no such merger,
consolidation or conveyance, transfer or lease shall be permitted if (1)
immediately after giving effect to such consolidation, merger, purchase,
conveyance, transfer, lease or other disposition, an Event of Default shall have
occurred and be continuing or (2) the surviving Person in such transaction has a
tangible net worth, as determined in accordance with generally accepted
accounting principles immediately following such transaction, of less than
seventy-five percent (75%) of Lessee, as measured immediately prior to such
transaction.

          Upon any consolidation or merger, or any conveyance, transfer or lease
of all or substantially all of the assets of the Lessee and the satisfaction of
the conditions specified in this Section 4.02(e), the successor corporation
formed by such consolidation or into which the Lessee is merged or the Person to
which such conveyance, transfer or lease is made shall succeed to, and be
substituted for, and may exercise every right and power of, the Lessee under
this Agreement and the Lease and each other Operative Agreement and any other
document contemplated hereby and thereby to which the Lessee is a party with the
same effect as if such successor corporation had been named as the Lessee herein
and therein. No such consolidation or merger, or sale, conveyance, transfer or
lease of all or substantially all of the assets of the Lessee as an entirety
shall have the effect of releasing the Lessee or any successor corporation which
shall theretofore have become the Lessee hereunder in the manner prescribed in
this Section 4.02(e) from its

                                       15

operation or possession of the Aircraft except in compliance with the applicable
provisions of the Lease.

          (f) CHANGE OF LOCATION. The Lessee agrees to give prompt written
notice (but in any event within 30 days prior to the expiration of the period of
time specified under Applicable Law to prevent lapse of perfection) to the Owner

     nor does the signer have knowledge of the existence as of the date of such
     certificate, of any condition or event which constituted or constitutes a
     Default or Event of Default, or, if any such condition or event existed or
     exists, specifying the nature and period of existence thereof and what
     action the Lessee has taken or is taking or proposes to take with respect
     thereof; and

               (iv) from time to time, such other non-confidential financial
     information as the Lessor or the Owner Participant may reasonably request.

financing statements required pursuant to Section 3.01(k) and all continuation
statements (and any amendments necessitated by any combination, consolidation or

country other than the United States pursuant to Section 4.02(b), Lessee will
furnish to Owner Trustee and Owner Participant annually after such registration
is effected, an opinion of special counsel reasonably satisfactory to Owner
Participant stating that, in the opinion of such counsel, either that (i) such
action has been taken with respect to the recording, filing, rerecording and
refiling of the Operative Agreements and any supplements and amendments thereof
as is necessary to establish, perfect and protect Owner Trustee's right, title
and interest in and to the Aircraft and the Operative Agreements, reciting the
details of such actions, or (ii) no such action is necessary to maintain the
perfection of such right, title and interest.

          Section 4.03. SURVIVAL OF REPRESENTATIONS AND WARRANTIES. The
representations and warranties of the Lessee provided in Section 4.01 and in any
other Operative Agreement shall survive the delivery of the Aircraft and the

     the other Operative Agreements to which it is or is to be a party and the
     Owner Participant knows of no pending or threatened actions or proceedings
     before any court, administrative agency or tribunal involving it in
     connection with the transactions contemplated by the Operative Agreements;

               (vi) neither the execution and delivery by it of this Agreement
     or the other Operative Agreements to which it is a party nor the
     performance of obligations hereunder or thereunder requires the consent or
     approval of or the giving of notice to, the registration with, or the
     taking of any other action in respect of, any governmental authority or
     agency that would be required to be obtained or taken by the Owner
     Participant except for filings contemplated by this Agreement;

               (vii) the funds to be used by the Owner Participant to acquire
     its interests under this Agreement do not constitute assets (within the
     meaning of ERISA and any applicable rules and regulations) of an ERISA
     Plan;

               (viii) the Owner Participant is a bank, trust company, insurance
     company, financial institution or corporation with a combined capital and
     surplus or net worth of at least $50,000,000;

     Guarantee Agreement and the Guarantee Agreement have not been disclosed to
     or reviewed by the Lessee;

               (x) the Owner Participant has not granted any right to the
     Manufacturer under the Residual Value Guarantee Agreement or the Guarantee
     Agreement which is inconsistent with the rights of the Lessee under the
     Operative Agreements; and

                                       18
<Page>

               (xi) the amount guaranteed by the Manufacturer under the Residual
     Value Guarantee Agreement is the Guaranteed Amount.

          Notwithstanding the foregoing or anything else contained in this
Agreement, the Owner Participant makes no representation or warranty in this
Agreement with respect to laws, rules or regulations relating to aviation or to
the nature or use of the equipment owned by the Owner Trustee, including,
without limitation, the airworthiness, value, condition, workmanship, design,
patent or trademark infringement, operation, merchantability or fitness for use
of the Aircraft, other than such laws, rules or regulations relating to the
citizenship requirements of the Owner Participant under applicable aviation law.

          (b) LESSOR'S LIENS. The Owner Participant represents, warrants and
covenants that on the Delivery Date there are no Lessor's Liens attributable to
it (or an Affiliate thereof). The Owner Participant agrees with and for the
benefit of the Lessee and the Owner Trustee that the Owner Participant will, at
its own cost and expense, take such action as may be necessary to duly discharge
and satisfy in full, promptly after the same first becomes known to the Owner
Participant, any Lessor's Lien attributable to the Owner Participant (or an
Affiliate thereof), PROVIDED, HOWEVER, that the Owner Participant shall not be
required to discharge or satisfy such Lessor's Lien which is being contested by
the Owner Participant in good faith and by appropriate proceedings so long as
such proceedings do not involve any material risk of the sale, forfeiture or
loss of the Aircraft or the Lessor's Estate or any interest in any thereof.

          (c) ASSIGNMENT OF INTERESTS OF OWNER PARTICIPANT. At any time after
the Delivery Date and subject to satisfaction of the conditions set forth in
this Section 5.01(c), the Owner Participant may assign, convey or otherwise
transfer to a single Person all (but not less than all) of the Beneficial
Interest, PROVIDED that (i) the Owner Participant gives the Lessee at least 10
days' notice of such assignment, conveyance or other transfer, (ii) the Owner
Participant and any Owner Participant Guarantor shall remain liable for all
obligations of the Owner Participant under the Trust Agreement and the other
Operative Agreements to which the Owner Participant is a party to the extent
(but only to the extent) relating to the period on or before the date of such
transfer, (iii) the transferee agrees by a written instrument substantially in
the form attached hereto as Exhibit B-1 (or otherwise in form and substance
reasonably satisfactory to Lessee) to assume liability for, and undertake
performance of, all obligations of the Owner Participant under the Trust
Agreement and the other Operative Agreements to which such Owner Participant is
a party relating to the period after the date of transfer, (iv) the transferee
shall make a representation to the effect that the funds to be used by the

Exhibit B-3 (or otherwise in form and substance reasonably satisfactory to
Lessee) (which counsel may be in-house counsel) to the effect that such
transferee and any guarantor of the payment and performance obligations of such
transferee, as the case may be, shall have requisite power and authority and
legal right to enter into and carry out the transactions contemplated hereby;
and that such agreement and any guaranty of the transferee's obligations has
been duly authorized, executed and delivered by the transferee or the guarantor
of the payment and performance obligations of such transferee, as the case may
be, and is a valid and binding agreement of the transferee or the guarantor of
the payment and performance obligations of such transferee enforceable in
accordance with its terms, subject to customary exceptions for such

                                       19
<Page>

opinions and that the transfer does not violate the Applicable Law of the
jurisdiction in which such counsel is located, and (vi) the Lessee shall have
received an opinion from counsel selected by Owner Participant and reasonably
acceptable to Lessee that no withholding tax will be imposed by the U.S. on
Basic Rent, assuming that the Lessee is a U.S. Person. Any such transferee shall
(a) be (i) a bank, savings institution, finance company, leasing company or
trust company, national banking association acting for its own account or in a
fiduciary capacity as trustee or agent under any pension, retirement, profit
sharing or similar trust or fund, insurance company, financial institution,
fraternal benefit society or a corporation acting for its own account having a
combined capital and surplus (or, if applicable, consolidated net worth or its
equivalent) of not less than $50,000,000, (ii) a subsidiary of any Person
described in clause (i) where such Person provides (A) support for the
obligations assumed by such transferee subsidiary reasonably satisfactory to the
Lessee and the Owner Trustee or (B) a guaranty of such transferee subsidiary's
obligations substantially in the form attached hereto as Exhibit B-2 (or
otherwise in form and substance reasonably satisfactory to Lessee and Owner
Trustee), or (iii) an Affiliate of the transferring Owner Participant, so long
as such Affiliate has a combined capital and surplus (or, if applicable,
consolidated net worth or its equivalent) of not less than $50,000,000 (unless
the Owner Participant remains liable for the obligations of such Affiliate under
the Operative Agreements, in which case there shall be no such net worth
requirement), (b) be legally capable of binding itself to the obligations of the
Owner Participant and shall expressly agree to assume all obligations of the
Owner Participant under the Trust Agreement and this Agreement and (c) provide
representations, warranties, and covenants substantially similar to those
contained in clauses (a) and (c) of this Section 5.01; PROVIDED that, without
the prior written consent of the Lessee, such transferee shall not be an airline
or other aircraft operator or competitor of the Lessee in the business of air
transportation or an Affiliate of any thereof unless such Affiliate is (i)
General Electric Company, International Lease Finance Corporation, GPA, GATX
Corporation or Bouillon Aviation, (ii) any wholly-owned subsidiary of an entity
listed in the foregoing clause (i) that is (X) a special purpose corporation
limited to holding Owner Participant's interest in the transactions or (Y)
primarily engaged in the business of owning and leasing assets to third-party
lessees and which is not engaged in the business of an airline, other commercial
aircraft operation or freight forwarder or (iii) an entity from which Lessee has
leased an aircraft directly (or through a trust) and not as a result of the
transfer to such entity of any aircraft subject to an existing lease with
Lessee; PROVIDED that Lessee's consent shall not be required if an Event of
Default shall have occurred and be continuing at the time of such transfer; and
PROVIDED FURTHER that neither such transferee nor any Affiliate thereof shall
(x) be a party to any material litigation or arbitration (whether as plaintiff
or defendant) with the Lessee or any Affiliate of the Lessee or (y) be
attempting a hostile takeover of the Lessee or any Affiliate of the Lessee. A
transferee hereunder shall be a Citizen of the United States or has established
a voting trust, voting powers or other arrangement reasonably satisfactory to
the Owner Trustee and the Lessee to permit the Owner Trustee to be the
registered owner of the Aircraft under the Transportation Code, without in any
way restricting the Lessee's use and operation of the Aircraft. The Owner
Trustee shall not be on notice of or otherwise bound by any such assignment,
conveyance or transfer unless and until it shall have received an executed
counterpart of the instrument of such assignment, conveyance or transfer. Upon
any such disposition by the Owner Participant to a transferee as above provided,
the transferee shall be deemed the "Owner Participant" for all purposes of the
Operative Agreements, and shall be deemed to have acquired the same interest in
the Lessor's Estate as theretofore held by its

                                       20
<Page>

transferor; and each reference therein to the "Owner Participant" shall
thereafter be deemed a reference to such transferee and the transferring Owner
Participant shall be released from all of its obligations under the Operative
Agreements to the extent such obligations are assumed by such transferee. All
reasonable fees and expenses incurred by Lessee, Owner Participant or Owner
Trustee in connection with any transfer by the Owner Participant permitted by
this Section 5.01(c) will be reimbursed by the Owner Participant, unless an
Event of Default has occurred and is continuing, in which case any fees and
expenses incurred by Lessee shall not be so reimbursed; PROVIDED, HOWEVER, that
in each case bills shall be submitted to the Owner Participant prior to payment.
Each of the parties hereto agree, to the extent so requested by the Owner
Participant, to use reasonable efforts to cooperate with the Owner Participant
in effecting any assignment, conveyance or other transfer permitted pursuant to
this Section 5.01(c), including providing its written consent and
acknowledgement to any such assignment, conveyance or other transfer and, in the
case of the Lessee, providing new insurance certificates that reflect the
interest of the transferee. After the expiration or termination of the Term of
the Lease, the Owner Participant may freely assign, convey or otherwise transfer
all or any part of the Beneficial Interest without compliance with this
Section 5.01(c), provided that no such transfer shall release the Owner
Participant from its obligations under the Operative Agreements accrued prior to
the end of the Term.

          (d) ACTIONS WITH RESPECT TO LESSOR'S ESTATE, ETC. The Owner
Participant agrees that it will not take any action to subject the Lessor's
Estate or the trust established by the Trust Agreement, as debtor, to the
reorganization or liquidation provisions of the Bankruptcy Code or any other
applicable bankruptcy or insolvency statute.

          (e) CITIZENSHIP. The Owner Participant agrees, solely for the benefit
of the Lessee and the Owner Trustee, that if at any time on or after the
Delivery Date when the Aircraft is registered or the Lessee proposes to register
the Aircraft in the United States (i) either the Owner Participant shall cease
to be, or an event which has been publicly disclosed has occurred of which the
Owner Participant has knowledge and which will cause the Owner Participant to
cease to be, a Citizen of the United States, and (ii) the Aircraft shall or
would therefore become ineligible for registration in the name of the Owner
Trustee under the Transportation Code and regulations then applicable thereunder
(such eligibility to be determined without regard to any provision of law that
permits the U.S. registration of the Aircraft by restricting where it is based
or used), then the Owner Participant shall give notice thereof to the Lessee and
the Owner Trustee and shall (at its own expense and without any reimbursement or
indemnification from the Lessee) immediately (and in any event within a period
of 20 days) promptly (x) effect a voting trust or other similar arrangement, (y)
transfer in accordance with the terms of this Agreement and the Trust Agreement
all its rights, title and interest in and to such Trust Agreement, the Lessor's
Estate and this Agreement, or (z) take any other alternative action that would
prevent any deregistration, or maintain or permit the United States
registration, of the Aircraft (determined without regard to any provision of law
that permits the U.S. registration of the Aircraft by restricting where it is
based or used). Each party hereto agrees, upon the request and at the sole
expense of the Owner Participant, to cooperate with the Owner Participant in
complying with its obligations under the provisions of the first sentence of
this Section 5.01(e), but without any obligation on the part of such other party
to take any action believed by it in good faith to be unreasonably burdensome to
such party or materially adverse to its business interests.

                                       21
<Page>

          (f) GUARANTEES. The Owner Participant agrees for the benefit of the
Lessee that it shall not make or consent to any changes to the Residual Value
Guarantee Agreement or the Guarantee Agreement that would make the
representation in Section 5.01(a)(x) incorrect at the time of such change or
that would increase the Guaranteed Amount and the Owner Participant agrees to
provide notice to the Lessee of any decrease in the Guaranteed Amount and the
amount of such decrease.

          Section 5.02. CITIZENSHIP.

          (a) GENERALLY. The Owner Trustee, in its individual capacity,
represents and warrants that it is and on the Delivery Date will be a Citizen of
the United States. If the Owner Trustee in its individual capacity does not
comply with the requirements of this Section 5.02, the Owner Trustee and the
Lessee hereby agree that no Default shall be deemed to exist due to
non-compliance by the Lessee with the registration requirements in the Lease or
in Section 4.02(b) hereof occasioned solely by such noncompliance of the Owner
Trustee.

          (b) OWNER TRUSTEE. The Owner Trustee, in its individual capacity,
covenants that if at any time on or after the Delivery Date any of its
Responsible Officers shall have actual knowledge that it has ceased to be a
Citizen of the United States, it will resign immediately as the Owner Trustee if
such citizenship is necessary for registration of the Aircraft in the Owner
Trustee's name under the Transportation Code as in effect at such time (such
necessity to be determined without regard to any provision of law that permits
the U.S. registration of the Aircraft by restricting where it is based or used)
or, if it is not necessary for such registration, if the Owner Trustee is
informed in writing by the Lessee or the Owner Participant that such lack of
United States citizenship would have any adverse effect on the Lessee or the
Owner Participant. The Owner Trustee, in its individual capacity, further
covenants that if at any time it appears reasonably probable that it will cease
to be a Citizen of the United States based on information that is (i) known to a
Responsible Officer of the Owner Trustee or (ii) generally known to the public,
it will promptly so notify, to the extent permitted by law, all parties to this
Agreement.

          Section 5.03. REPRESENTATIONS, WARRANTIES AND COVENANTS OF TRUST
COMPANY AND THE OWNER TRUSTEE.

     federal or governmental authority or agency governing its banking or trust

               (vi) the rentals (including Basic Rent and Supplemental Rent),

<Page>

               (vii) in the case of the Owner Participant, any "prohibited
     transaction," within the meaning of Section 406 of ERISA or
     Section 4975(c)(1) of the Code, arising out of or in connection with the
     acquisition or holding of the Owner Participant's interest in the
     Trust Estate.

not extend to any of the following:

     States or any state or local taxing authority in any state in the United
     States) as a result of (I) the operation, registration, location, presence,

     Lessee or any Affiliate thereof or any Sublessee having made (or having
     been deemed to have made) payments to such Tax Indemnitee from the
     jurisdiction of the taxing authority imposing such Tax,;

     expiration of the Term of the Lease or (C) the termination of the Lease in
     accordance with the applicable provisions of the Lease thereof;

     including revocation of the Trust, of any interest in some or all of the

     to the Lessor's exercise of remedies in accordance with Section 17 of the
     Lease, (C) termination of the Lease upon the Lessee's exercise of Lessee's
     options pursuant to Section 14 of the Lease, or (D) a transfer to Lessee

     minimize any such Taxes covered by this provision;

               (vi) Taxes subject to indemnification by the Lessee pursuant to
     the Tax Indemnity Agreement;

               (vii) Taxes imposed on a successor, assign or other transferee of
     any interest of a Tax Indemnitee in the Aircraft, any Engine or any Part or
     any Operative Agreement or any proceeds thereunder to the extent that the
     aggregate amount of such Taxes exceeds the aggregate amount of Taxes that
     would have been imposed on the transferor (determined at the time of the
     transfer) and that would have been indemnifiable pursuant to
     Section 6.01(a) hereof, provided that the exclusion in this clause (vii)
     shall not apply in the case of any such sale, assignment, transfer or
     disposition that occurs in connection with an Event of Default or in
     connection with a bankruptcy, insolvency or other proceeding for the relief
     of debtors in which the Lessee is a debtor;

               (viii) Any Taxes which have been properly included in the

     resulting from, arising out of or in connection with a "prohibited
     transaction" within the meaning of Section 406 of ERISA or

     assets of any ERISA Plan to acquire or hold Owner Participant's interest in
     the Trust Estate or in the case of any transferee of the Owner Participant
     referred to in Section 5.01(c), to purchase the Beneficial Interest
     pursuant to Section 5.01(c);

               (xi) Taxes that are being contested in accordance with the
     provisions hereof;

               (xii) United States withholding Taxes imposed on the Owner

     or

               (xiii) interest, penalties, fines or additions to tax to the
     extent they relate to Taxes for which no indemnity would be payable by
     Lessee pursuant to this Section 6.01(b).

                                       28

          Section 6.02. AFTER TAX BASIS. The amount which the Lessee shall be
required to pay with respect to any Tax indemnified against under Section 6.01
(an "Indemnifiable Tax") shall be an amount sufficient to restore the Tax
Indemnitee, on an After Tax Basis, to the same position such party would have
been in had such Tax not been incurred, taking into account any tax benefits
recognized by such Tax Indemnitee as a result of the Indemnifiable Tax. If any
Tax Indemnitee actually realizes a tax benefit (whether by credit, deduction or
otherwise), or would have realized such a benefit as to which it has been given
notice if properly claimed, and with respect to Owner Participant, the Owner
Participant has not determined in good faith that claiming such benefit would
have a material adverse impact on the Owner Participant or an Affiliate thereof,
by reason of the payment of any Tax paid or indemnified against by the Lessee,
provided that an Event of Default has not occurred and is not continuing, such
Tax Indemnitee shall promptly pay to the Lessee, to the extent such tax benefit
was not previously taken into account in computing such payment or indemnity,
but not before the Lessee shall have made all payments then due to such Tax
Indemnitee under this Agreement, the Tax Indemnity Agreement and any other
Operative Agreement, an amount equal to the lesser of (x) the sum of such tax
benefit plus any other tax benefit realized by such Tax Indemnitee that would
not have been realized but for any payment made by such Tax Indemnitee pursuant
to this sentence and not already paid to the Lessee, or (y) the amount of the
payment made under Section 6.01 hereof and this Section 6.02 by the Lessee to
such Tax Indemnitee plus the amount of any other payments by the Lessee to such
Tax Indemnitee theretofore required to be made under this Section 6.02 and
Sections 6.01 and 6.05 hereof (and the excess, if any, of the tax benefit over
the applicable amount described in clause (x) over the amount described in
clause (y) above shall be carried forward and applied to reduce PRO TANTO any
subsequent obligations of the Lessee to make payments to such Tax Indemnitee
pursuant to Section 6.01 hereof). If an amount payable by any Tax Indemnitee to
the Lessee pursuant to this Section 6.02 is not paid when due because of the
occurrence and continuation of any Event of Default, such amount shall be
payable by any Tax Indemnitee to the Lessee upon the Lessee's curing all Events
of Default. The Lessee shall reimburse on an After Tax Basis such Tax Indemnitee
(subject to Section 6.01(b), but only insofar as subsections (iv), (vi), (vii),
(ix), (x), (xi), (xii) and (xiii) thereof would apply) for any payment of a tax
benefit pursuant to the preceding sentence (or a tax benefit otherwise taken
into account in calculating the Lessee's indemnity obligation hereunder) to the
extent that such tax benefit is subsequently disallowed or reduced.

          In determining the order in which any Tax Indemnitee utilizes
withholding or other foreign taxes as a credit against such Tax Indemnitee's
United States income taxes, such Tax Indemnitee shall be deemed to utilize (i)
first, all foreign taxes other than those described in clause (ii) below; and
(ii) then, on a pro rata basis, all foreign taxes with respect to which such Tax
Indemnitee is entitled to obtain indemnification pursuant to an indemnification
provision contained in any lease, loan agreement, or other financing document
(including this Agreement) that is similar to the indemnification provision in
this Article 6.

          Section 6.03. TIME OF PAYMENT. Any amount payable to a Tax Indemnitee
pursuant to this Article 6 shall be paid promptly, but in any event within 30
days after receipt of a written demand therefor from such Tax Indemnitee
accompanied by a written statement describing in reasonable detail the basis for
such indemnity and the computation of the amount so payable, PROVIDED that in
the case of amounts which are being contested by the Lessee in good faith or by
the Tax Indemnitee in either case pursuant to Section 6.04 hereof, or subject to

                                       29
<Page>

verification proceedings pursuant to Section 6.11 hereof, such amount shall be
payable within 30 days after the time such contest or verification proceeding,
as the case may be, is finally resolved. In no event shall any amount be payable
under Section 6.01 until two Business Day prior to the due date for Tax
in issue.

          Section 6.04. CONTESTS.

          (a) NOTICE OF CLAIM. If a written claim is made against any Tax
Indemnitee for Taxes with respect to which the Lessee is liable for a payment or
indemnity hereunder, such Tax Indemnitee shall promptly (but in any event within
30 days of receipt thereof) give the Lessee notice in writing of such claim and
shall furnish the Lessee with copies of any written requests for information
sent to such Tax Indemnitee from any taxing authority to the extent relating to
such Taxes with respect to which the Lessee may be required to indemnify
hereunder; PROVIDED, HOWEVER, that the failure of a Tax Indemnitee to give such
notice or furnish such copy shall not terminate any of the rights of such Tax
Indemnitee under this Article 6, except (A) to the extent that the Lessee's
contest rights have been materially and adversely impaired by the failure to
provide such notice or copy or (B) to the extent that such failure results in
the imposition of, or an increase in the amount of, any penalties, interest or
additions to Tax related to the Tax which is the subject of such claim
or proceeding.

          (b) REQUEST FOR CONTEST. If a written claim shall be made against any
Tax Indemnitee for any Tax, other than an Income Tax, for which the Lessee may
be obligated to indemnify pursuant to Section 6.01 hereunder, and under
applicable law of the taxing jurisdiction the Lessee is allowed to contest
directly such Tax and the Tax to be contested is not reflected in a report or
return with other Taxes of any Tax Indemnitee (as confirmed in writing by such
Tax Indemnitee) and if the Tax Indemnitee determines in good faith that it will
not suffer any adverse consequences as a result and that no tax return of the
Tax Indemnitee will be kept open as a result of such contest beyond the
applicable statute of limitations period (as confirmed in writing by such Tax
Indemnitee), then the Lessee shall be permitted, at its expense and in its own
name, or, if consented to in writing by the Tax Indemnitee, in the name of such
Tax Indemnitee, to contest the imposition of such Tax (a " Lessee Controlled
Contest"); PROVIDED, HOWEVER, that the Lessee shall not be permitted or entitled
to contest any Tax unless (A) such contest will not result in the risk of an
imposition of criminal penalties or a more than de minimis risk of a sale,
forfeiture or loss of the Aircraft, the Airframe, the Engines or any part
thereof or the creation of any Lien other than Liens for Taxes of the Lessee (x)
either not yet due or being contested in good faith by appropriate proceedings
so long as such proceedings do not involve the risk of an imposition of criminal
penalties or a more than de minimis risk of any sale, forfeiture or loss of the
Aircraft (unless the Lessee has provided a bond or other sufficient protection
against any such risk reasonably satisfactory to the Tax Indemnitee), and (y)
for the payment of which such reserves, if any, as required to be provided under
generally accepted accounting principles have been provided and, to the extent
permitted by law, the Lessee shall be entitled to withhold payment during
pendency of such contest, (B) if an Event of Default shall have occurred and be
continuing, the Lessee shall have provided security for its obligations
hereunder reasonably satisfactory to the Owner Participant by placing in escrow
funds to cover any such obligations, (C) the Lessee shall have agreed to pay
such Tax Indemnitee on demand and on an After Tax Basis all costs and expenses
that such Tax Indemnitee actually incurs in connection with contesting such
claim (including, without limitation, all costs, expenses, losses, reasonable
legal

                                       30
<Page>

and accounting fees, disbursements, or penalties, interest and addition to tax),
(D) if such contest shall be conducted in a manner requiring the payment of the
claim in advance, the Lessee shall have advanced sufficient funds, on an
interest free basis, to make the payment required (or the Lessee shall have paid
the amount required directly to the appropriate taxing authority), and agreed to
indemnify the Tax Indemnitee against any additional net adverse tax consequences
on an After Tax Basis to such Tax Indemnitee of such advance, and (E) if
requested by the Owner Participant, independent tax counsel selected by Owner
Participant and reasonably acceptable to the Lessee has rendered an opinion
within 30 days of the Owner Participant providing notice of the claim to the
Lessee that a Reasonable Basis exists for contesting such claim.

          If the Lessee shall so request within 30 days after receipt of such
notice from a Tax Indemnitee under this Section 6.04 hereof and with respect to
a Tax for which the Lessee may be obligated to indemnify pursuant to
Section 6.01 and which does not satisfy the requirements to constitute a Lessee
Controlled Contest, such Tax Indemnitee shall in good faith at the Lessee's
after-tax expense contest the imposition of such Tax; PROVIDED, HOWEVER, that
such Tax Indemnitee, after considering in good faith any advice of the Lessee
and the Lessee's counsel concerning the forum in which the adjustment is most
likely to be favorably resolved, may in its sole discretion select the manner
and forum for such contest and determine whether any such contest shall be made
by (a) resisting payment thereof if lawful and practicable or not paying the
same except under protest if protest is necessary and proper in each case so
long as non-payment will not result in a more than de minimis risk of the sale,
forfeiture or loss of, or the creation of a Lien other than a Permitted Lien on
the Aircraft, Airframe or any Engine or any risk of criminal liability; or (b)
if the payment be made, using reasonable efforts to obtain a refund thereof in
appropriate administrative and/or judicial proceedings; PROVIDED FURTHER,
HOWEVER, that at such Tax Indemnitee's option, such contest shall be conducted
by the Lessee in the name of such Tax Indemnitee if such Tax Indemnitee so
requests in writing and that in no event shall such Tax Indemnitee be required
or the Lessee permitted to contest under this paragraph the imposition of any
Tax for which the Lessee may be obligated pursuant to this Section 6.01 unless:

               (i) in the case of an Income Tax, the Lessee shall have furnished
     at the Lessee's expense an opinion of counsel selected by the Lessee and
     reasonably satisfactory to such Tax Indemnitee to the effect that a
     Reasonable Basis exists for pursuing such contest;

               (ii) the Lessee shall have agreed to pay such Tax Indemnitee on
     demand and on an After Tax Basis all reasonable costs and expenses that
     such Tax Indemnitee may incur in connection with contesting such claim
     (including, without limitation, all costs expenses, losses, reasonable
     legal and accounting fees, disbursements, penalties, interest and additions
     to tax);

               (iii) such Tax Indemnitee shall have determined that the action
     to be taken will not result in any more than de minimis danger of sale,
     forfeiture or loss of, or the creation of any Lien other the Liens for
     Taxes of the Lessee (or any Sublessee) either not yet due or being
     contested in good faith by appropriate proceedings so long as such
     proceedings do not involve any more than de minimis risk of the sale,
     forfeiture or loss of the Aircraft, the Airframe or any Engine or any
     interest therein (unless the Lessee has

                                       31
<Page>

     provided a bond or other sufficient protection against any such risk
     reasonably satisfactory to the Tax Indemnitee) and for the payment of
     which such reserves, if any, as are required to be provided under generally
     accepted accounting principles have been provided;

               (iv) if an Event of Default shall have occurred and be
     continuing, the Lessee shall have provided security for its obligations
     hereunder reasonably satisfactory to the Owner Participant by placing in
     escrow sufficient funds to cover any such obligations;

               (v) Lessee shall have acknowledged its liability for such claims;

               (vi) such contest and related contests involving other equipment
     involve potential payments and/or indemnities by the Lessee (whether or not
     such indemnity is pursuant to this Agreement) of at least $25,000 in the
     aggregate; and

               (vii) if such contest shall be conducted in a manner requiring
     the payment of the claim in advance, the Lessee shall have advanced
     sufficient funds, on an interest free basis, to make the payment required,
     and agreed to indemnify the Tax Indemnitee against any additional net
     adverse tax consequences on an After Tax Basis to such Tax Indemnitee of
     such advance.

          In the case of a contest which is not a Lessee Controlled Contest, if
requested by the Lessee, the Tax Indemnitee shall appeal any adverse
administrative or judicial decision, except that the Tax Indemnitee shall not be
required to appeal any adverse decision to the United States Supreme Court
provided that with respect to an appeal of an adverse judicial decision a
substantial basis in law and fact must exist that such appeal will be
successful. If the Lessee is permitted under applicable law to contest a Tax
asserted against the Lessee and the same or similar Tax is also asserted against
the Tax Indemnitee, subject to the conditions herein, each of the Lessee and
such Tax Indemnitee shall conduct its contest in its own name and the Lessee and
such Tax Indemnitee will cooperate in a reasonable manner with respect to the
respective contests of such Tax.

          (c) DECLINING TO CONTEST; SETTLEMENT.

               (i) If, after the Lessee has properly requested a contest in
     accordance with this Section 6.04 and Lessee is then complying with the
     terms of this Section 6.04, any Tax Indemnitee shall at any time decline to
     take any action required under Section 6.04 with respect to such contest,
     then, if such failure shall cause the contest to be determined adversely or
     shall preclude such contest as a matter of law, the Lessee shall not be
     obligated to indemnify such Tax Indemnitee for such Tax and such Tax
     Indemnitee shall reimburse the Lessee for all amounts previously advanced
     by the Lessee in connection with such contest (other than costs and
     expenses of such contest).

               (ii) No Tax Indemnitee shall settle a contest of any indemnified
     Tax without requesting the Lessee's written consent (which consent will not
     be unreasonably withheld, as determined in the Lessee's good faith
     judgment). If any Tax Indemnitee shall settle a contest for any Tax without
     receiving the Lessee's written consent, then the

                                       32
<Page>

     Lessee shall not be obligated to indemnify such Tax Indemnitee for such Tax
     and the Tax Indemnitee shall reimburse the Lessee for all amounts
     previously advanced with respect to such contest (other than costs and
     expenses of such contest). Notwithstanding the preceding two sentences, no
     Tax Indemnitee shall be required to take or continue any action unless the
     Lessee shall have agreed to pay the Tax Indemnitee on a current and After
     Tax Basis all reasonable fees and expenses (including reasonable attorney's
     and accountant's fees) which such Tax Indemnitee may incur as a result of
     contesting such Taxes.

          (d) CONTINUING CLAIMS. Notwithstanding anything contained in this
Section 6.04 to the contrary, no Tax Indemnitee shall be required to contest any
claim if the subject matter thereof shall be of a continuing nature and shall
have previously been adversely decided pursuant to the contest provisions of
this Section 6.04 unless there shall have been a change in the law (including,
without limitation, amendments to statutes or regulations, administrative
rulings and court decisions) or the Lessee shall have provided new facts after
such claim shall have been so previously decided, and such Tax Indemnitee shall
have received an opinion of independent tax counsel selected by it and
reasonably approved by the Lessee and furnished at the Lessee's sole expense to
the effect that, as a result of such change or new facts, it is more likely than
not that the position which such Tax Indemnitee or the Lessee, as the case may
be, had asserted in such previous contest, would prevail.

          (e) CLAIMS BARRED. If (A) any Tax Indemnitee fails to give the Lessee
written notice pursuant to this Section 6.04 of any claim by any government or
taxing authority for any Tax for which the Lessee is obligated pursuant to this
Section 6.01, (B) as a direct result of such failure the contest of such claim
has been materially and adversely impaired and (C) the Lessee furnishes, at the
Lessee's expense, an opinion of counsel selected by the Lessee and reasonably
satisfactory to such Tax Indemnitee to the effect that, had the contest of such
claim not been materially and adversely impaired, a Reasonable Basis would have
existed for pursuing such contest, such Tax Indemnitee shall be deemed to have
waived its right to any payment by the Lessee that would otherwise be payable by
the Lessee pursuant to this Section 6.01 in respect of such claim.

          Section 6.05. REFUNDS. When a Tax Indemnitee becomes entitled to
receive a refund or credit against Tax of all or any part of any Taxes which the
Lessee shall have paid for such Tax Indemnitee or for which the Lessee shall
have reimbursed or indemnified such Tax Indemnitee, such Tax Indemnitee shall
pay, provided an Event of Default has not occurred and is not continuing, to the
Lessee an amount equal to the amount of such refund or credit, together with any
interest attributable thereto, less (x) all payments then due to such Tax
Indemnitee under this Article 6, and (y) Taxes imposed with respect to the
accrual or receipt thereof, including interest received attributable thereto,
plus any tax benefit realized by such Tax Indemnitee as a result of any payment
by such Tax Indemnitee made pursuant to this sentence; PROVIDED, HOWEVER, that
such amount shall not be payable (a) before such time as the Lessee shall have
made all payments or indemnities then due and payable to such Tax Indemnitee
under this Article 6 and (b) to the extent that the amount of such payment
(without regard to any interest component thereof) would exceed (i) the amount
of all prior payments by the Lessee to such Tax Indemnitee pursuant to this
Article 6 less (ii) the amount of all prior payments by such Tax Indemnitee to
the Lessee pursuant to this Article 6 (any such excess shall be carried forward
to

                                       33
<Page>

reduce PRO TANTO any subsequent obligations of the Lessee to make payments to
such Tax Indemnitee pursuant to Section 6.01 hereof). If an amount payable by
any Tax Indemnitee to the Lessee pursuant to this Section 6.02 is not paid when
due because of the occurrence and continuation of an Event of Default, such
amount shall be payable by any Tax Indemnitee to the Lessee upon the Lessee's
curing all Events of Default.

          Any subsequent loss of such refund or tax benefit shall be treated as
a Tax subject to indemnification under the provisions of this Article 6 (in the
case of any such tax benefit, subject to Section 6.01(b) but only insofar as
subsections (iv), (vi), (vii), (ix),(x), (xi), (xii) and (xiii) thereof would
apply).

          Section 6.06. REPORTS. In case any report or return is required to be
made with respect to any Taxes (other than Income Taxes) against which the
Lessee is or may be obligated to indemnify the Indemnitees under this Article 6,
the Lessee shall, to the extent it has knowledge thereof, make such report or
return, except for any such report or return that the Tax Indemnitee has
notified the Lessee that it intends to file, in such manner as will show the
ownership of the Aircraft in the Owner Trustee (unless the ownership of the
Aircraft is not shown on such report or return) and, upon request, shall send a
copy of the applicable portions of such report or return to the Tax Indemnitee
and the Owner Trustee or will notify the Tax Indemnitee of such requirement and
make such report or return in such manner as shall be satisfactory to such Tax
Indemnitee and the Owner Trustee. The Lessee will provide such information
within the possession or control of the Lessee as the Tax Indemnitee may
reasonably request in writing from the Lessee to enable the Tax Indemnitee to
fulfill its tax filing requirements with respect to the transactions
contemplated by the Operative Agreements (without duplication of any comparable
requirements of the Tax Indemnity Agreement) and any audit information request
arising from any such filing. The Tax Indemnitee will provide such information
within its possession or control as the Lessee may reasonably require from such
Tax Indemnitee to enable the Lessee to fulfill its tax filing requirements with
respect to the transactions contemplated by the Operative Agreements and any
audit information request arising from such filing; PROVIDED that in no event
shall any Tax Indemnitee be required to provide copies of any of its
tax returns.

          Section 6.07. SURVIVAL OF OBLIGATIONS. The representations,
warranties, indemnities and agreements of the Lessee provided for in this
Article 6 and the Lessee's obligations under any and all of them, in each case,
with respect to events or periods prior to the expiration or termination of the
Lease shall survive the expiration or other termination of the Operative
Agreements.

          Section 6.08. PAYMENT OF TAXES. With respect to any Tax otherwise
indemnifiable hereunder by the Lessee and applicable to the Aircraft, Airframe,
any Engine or Parts, to the extent permitted by the applicable federal, state,
local or foreign law, the Lessee shall pay such tax directly to the relevant
Taxing authority and file any returns or reports required with respect thereto
to the extent legally entitled to do so in its own name; PROVIDED, HOWEVER, that
the Lessee shall not make any statements or take any action which would indicate
that the Lessee or any Person other than the Owner Trustee or Owner Participant
is the owner of the Aircraft, the Airframe, any Engine or any Part or which
would otherwise be inconsistent with

                                       34
<Page>

the terms of the Lease or the Tax Indemnity Agreement and the position
thereunder of the Owner Trustee and the Owner Participant.

          Section 6.09. REIMBURSEMENTS BY INDEMNITEES GENERALLY. To the extent
the Lessee is required to pay or withhold any Tax imposed on or with respect to
a Tax Indemnitee in respect of the transactions contemplated by the Operative
Agreements, which Tax is not otherwise the responsibility of the Lessee under
the Operative Agreements, or any other written agreements between the Lessee and
such Tax Indemnitee, then such Tax Indemnitee shall pay to the Lessee within 30
days of the Lessee's demand therefor an amount which equals the amount actually
paid by the Lessee with respect to such Taxes.

          Section 6.10. FORMS. Each Tax Indemnitee agrees to furnish from time
to time to Lessee or to such other person as Lessee may designate, at Lessee'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, (y) Lessee has provided such Tax Indemnitee
with any information necessary to complete such form not otherwise reasonably
available to such Tax Indemnitee, and (z) with respect to Owner Participant, the
Owner Participant has determined in good faith that furnishing such form could
not have a material adverse impact on the Owner Participant or an Affiliate
thereof.

          Section 6.11. VERIFICATION. At the Lessee's request, the accuracy of
any calculation of amount(s) payable pursuant to this Article 6 shall be
verified by independent public accountants selected by the applicable Tax
Indemnitee and reasonably satisfactory to the Lessee, and such verification
shall bind the applicable Tax Indemnitee and the Lessee. In order, and to the
extent necessary, to enable such independent accountants to verify such amounts,
such Tax Indemnitee shall provide to such independent accountants (for their
confidential use and not to be disclosed to the Lessee or any other person) all
information reasonably necessary for such verification. Verification shall be at
the expense of the Lessee, unless such verification results in an adjustment in
the Lessee's favor of $10,000 or more of the amount of the payment as computed
by such Tax Indemnitee, in which case the verification shall be at the expense
of the Tax Indemnitee.

          Section 6.12. NON-PARTIES. If a Tax Indemnitee is not a party to this
Agreement, Lessee may require the Tax Indemnitee to agree in writing, in a form
reasonably acceptable to Lessee, to the terms of this Article 6 prior to making
any payment to such Tax Indemnitee hereunder.

                                   ARTICLE 7.
                                GENERAL INDEMNITY

          Section 7.01. GENERALLY.

          (a) INDEMNITY. The Lessee agrees to indemnify each Indemnitee against
and agrees to protect, defend, save and keep harmless each Indemnitee from and
against and in respect of, and will pay on an After Tax Basis, any and all
liabilities, obligations, losses, damages, settlements, penalties, claims,
actions, suits, costs, disbursements and expenses,

                                       35
<Page>

demands or judgments (including reasonable legal fees and expenses) of every
kind and nature, whether or not any of the transactions contemplated by this
Agreement are consummated and whether arising before, on or after the Delivery
Date (individually, an "Expense," collectively, "Expenses"), which may be
imposed on, incurred or suffered by or asserted against any Indemnitee, in any
way relating to, arising out of or in connection with, any one or more of the
following:

               (i) any Operative Agreement, Sublease or any transaction
     contemplated thereby;

               (ii) the operation, possession, use, non-use, maintenance,
     storage, overhaul, delivery, non-delivery, control, condition, alteration,
     modification, addition, improvement, airworthiness, replacement,
     substitution, return, abandonment, redelivery or other disposition, repair
     or testing of the Aircraft, Airframe, or any Engine or any engine used in
     connection with the Airframe, or any Part thereof by the Lessee, any
     sublessee or any other Person whatsoever, whether or not such operation,
     possession, use, non-use, maintenance, storage, overhaul, delivery,
     non-delivery, control, condition, alteration, modification, addition,
     improvement, airworthiness, replacement, substitution, return, abandonment,
     redelivery or other disposition, repair or testing is in compliance with
     the terms of the Lease, including, without limitation, claims for death,
     personal injury or property damage or other loss or harm to any Person
     whatsoever, including, without limitation, any passengers, shippers or
     other Persons wherever located, claims or penalty relating to any laws,
     rules or regulations, including, without limitation, environmental control,
     noise and pollution laws, rules or regulation and any Liens in respect of
     the Aircraft, any Engine or any Part;

               (iii) the manufacture, design, sale, return, purchase,
     acceptance, nonacceptance, rejection, delivery, non-delivery, condition,
     repair, modification, servicing, rebuilding, airworthiness, registration,
     reregistration, deregistration, ownership, financing, import, export,
     performance, non-performance, lease, sublease, transfer, merchantability,
     fitness for use, alteration, substitution or replacement of any Airframe,
     Engine, or Part or other transfer of use or possession, or other
     disposition of the Aircraft, the Airframe, any Engine or any Part
     including, without limitation, latent and other defects, whether or not
     discoverable, tort liability, whether or not arising out of the negligence
     of any Indemnitee (whether active, passive or imputed and including strict
     liability without fault), and any claims for patent, trademark or copyright
     infringement;

               (iv) any breach of or failure to perform or observe, or any other
     non-compliance with, any condition, covenant or agreement to be performed,
     or other obligations of the Lessee under any of the Operative Agreements,
     or the falsity or inaccuracy of any representation or warranty of the
     Lessee in any of the Operative Agreements (other than representations and
     warranties in the Tax Indemnity Agreement) or the occurrence of any Default
     or Event of Default;

               (v) the enforcement of the terms of the Operative Agreements
     (including this Section 7.01(a));

                                       36
<Page>

               (vi) any interest in the Lessor's Estate or the Trust Agreement
     or any similar interest; and

               (vii) in the case of the Owner Participant, any "prohibited
     transaction," within the meaning of Section 406 of ERISA or
     Section 4975(c)(1) of the Code, arising out of or in connection with the
     acquisition or holding of the Owner Participant's interest in the Trust
     Estate.

          (b) EXCEPTIONS. The indemnity provided for in Section 7.01(a) shall
not extend to any Expense of any Indemnitee to the extent it:

               (i) is attributable to the willful misconduct or gross negligence
     of such Indemnitee (other than gross negligence or willful misconduct
     imputed to such person by reason of its interest in the Aircraft or any
     transaction documents);

               (ii) except to the extent fairly attributable to acts or events
     occurring prior thereto, is attributable to acts or events (other than the
     performance by Lessee of its obligations pursuant to the terms of the
     Operative Agreements) which occur after the Aircraft is no longer part of
     the Lessor's Estate or, if the Aircraft remains a part of the Lessor's
     Estate, after the expiration of the Term (unless the Aircraft is being
     returned at such time, in which case after return of physical possession;
     PROVIDED that if the Lease has been terminated pursuant to Section 17
     thereof, the indemnity provided in Section 7.01(a) hereof shall survive for
     so long as Lessor shall be exercising remedies under such Section 17), or
     to acts or events which occur after return of possession of the Aircraft by
     the Lessee in accordance with the provisions of the Lease (subject to the
     foregoing proviso if the Lessor has terminated the Lease pursuant to
     Section 17 of the Lease); PROVIDED that nothing in this clause (ii) shall
     be deemed to exclude or limit any claim that any Indemnitee may have under
     Applicable Law by reason of an Event of Default or for damages from Lessee
     for breach of Lessee's covenants contained in the Lessee Documents or to
     release Lessee from any of its obligations under the Lessee Documents that
     expressly provide for performance after termination of the Term;

               (iii) other than as expressly provided herein or in the other
     Operative Agreements, is a Tax or loss of a Tax benefit, whether or not the
     Lessee is required to indemnify therefor pursuant to Article 6 hereof or
     pursuant to the Tax Indemnity Agreement;

               (iv) is a cost or expense expressly required to be paid by such
     Indemnitee or its permitted transferees (and not by the Lessee) pursuant to
     this Agreement or any other Operative Agreement and for which the Lessee is
     not otherwise obligated to reimburse such Indemnitee, directly or
     indirectly pursuant to the terms of this Agreement or such other Operative
     Agreement;

               (v) is attributable to the incorrectness or breach by such
     Indemnitee of its representations or warranties, under any of the Operative
     Agreements except to the extent such incorrectness or breach was caused by
     a breach by Lessee of any

                                       37
<Page>

     representation or warranty or by any failure of Lessee to perform any
     obligation under an Operative Agreement;

               (vi) is attributable to the failure by such Indemnitee to perform
     any of its obligations under any of the Operative Agreements except to the
     extent such failure was caused by a breach by Lessee of any representation
     or warranty or by any failure of Lessee to perform any obligation under an
     Operative Agreement;

               (vii) is, in the case of the Owner Participant, Lessor's Liens
     attributable to the Owner Participant; in the case of the Owner Trustee,
     Lessor's Liens to the extent attributable to the Owner Trustee; in the case
     of Trust Company, Lessor's Liens to the extent attributable to Trust
     Company;

               (viii) is, in the case of the Owner Participant or the Owner
     Trustee, attributable to the offer or sale by such Indemnitee of any
     interest in the Aircraft, the Lessor's Estate or the Trust Agreement or any
     similar interest (including an offer or sale resulting from bankruptcy or
     other proceedings for the relief of debtors in which such Indemnitee is the
     debtor), unless in each case such offer or sale shall occur pursuant to the
     exercise of remedies under Section 17 of the Lease;

               (ix) in the case of the Owner Participant, is an Expense relating
     to, resulting from, arising out of or in connection with a "prohibited
     transaction" within the meaning of Section 406 of ERISA or
     Section 4975(c)(1) of the Code resulting from the direct or indirect use of
     assets of any ERISA Plan to acquire or hold Owner Participant's interest in
     the Trust Estate or in the case of any transferee of the Owner Participant
     referred to in Section 5.01(c), to purchase the Beneficial Interest
     pursuant to Section 5.01(c);

               (x) except during the continuation of an Event of Default, is
     attributable to any amendment to any of the Operative Agreements which is
     not requested, or consented to, by the Lessee or is not required or made
     pursuant to the terms of any of the Operative Agreements;

               (xi) is attributable to the exercise by any Indemnitee of any
     right to inspect the Aircraft except with respect to any such inspection
     conducted while an Event of Default is continuing; and

               (xii) constitutes the loss of future profits of such Indemnitee
     or losses attributable to such Indemnitee's overhead.

          Section 7.02. NOTICE AND PAYMENT. Each Indemnitee shall give prompt
written notice to the Lessee of any liability as to which an officer of such
Indemnitee has actual knowledge, for which the Lessee is, or may be, liable
under this Article 7; PROVIDED, HOWEVER, that failure to give such notice shall
not terminate any of the rights of an Indemnitee under this Article 7 and shall
not release Lessee from any of its obligations to indemnify such Indemnitee
hereunder, except to the extent that such failure adversely affects any
applicable defense or counterclaim, otherwise increases the amount the Lessee
would have been liable for in the

                                       38
<Page>

absence of such failure to provide such notice or adversely affects the ability
of Lessee's insurers to defend such claim.

          Section 7.03. DEFENSE OF CLAIMS. The Lessee or its insurers shall have
the right (in each such case at the Lessee's sole expense) to investigate,
defend (and control the defense of) any such claim for which indemnification is
sought pursuant to this Article 7 (so long as Lessee has agreed in writing
reasonably acceptable to the relevant Indemnitee that Lessee is liable to such
Indemnitee for any Expenses relating to or arising out of the claim for which
indemnification is sought, provided that Lessee will not be so liable to the
extent that it is reasonably determined that one or more of the exclusions
contained in Section 7.01(b) would be applicable to such claim) and each
Indemnitee shall cooperate with the Lessee or its insurers with respect thereto,
PROVIDED THAT, without limiting the right of the Lessee's insurers to assume and
control the defense of or to compromise, any such claim, the Lessee shall not be
entitled to assume and control the defense of or compromise any such claim (A)
during the continuance of any Event of Default arising under Sections 16(a),
(b), (f), (g) or (h) of the Lease, (B) if an actual or potential material
conflict of interest exists making it advisable in the good faith opinion of
such Indemnitee (on the basis of prevailing standards of professional
responsibility) for such Indemnitee to be represented by separate counsel or if
such proceeding involves the potential imposition of criminal liability on such
Indemnitee or (C) if such proceeding will involve any non-de minimis risk of the
sale, forfeiture or loss of, or the creation of any Lien (other than Permitted
Liens) on the Aircraft or the Trust Estate (unless the Lessee posts a bond or
other security reasonably acceptable in form and substance to such Indemnitee)
or involve any risk of criminal liability to such Indemnitee. Subject to the
immediately foregoing sentence, where the Lessee or the insurers under a policy
of insurance maintained by the Lessee undertake the defense of an Indemnitee
with respect to such a claim, no additional legal fees or expenses of such
Indemnitee in connection with the defense of such claim shall be indemnified
hereunder unless the fees or expenses were incurred at the written request of
the Lessee or such insurers. Subject to the requirement of any policy of
insurance applicable to a claim, an Indemnitee may participate at its own
expense at any judicial proceeding controlled by the Lessee or its insurers
pursuant to the preceding provisions, to the extent that such party's
participation does not, in the reasonable opinion of the independent counsel
appointed by the Lessee or its insurers to conduct such proceedings, interfere
with the defense of such claim (it being agreed that the making of copies,
giving notice of proceedings and the like shall not be considered interference);
and such participation shall not constitute a waiver of the indemnification
provided in this Section 7.03. No Indemnitee shall enter into any settlement or
other compromise with respect to any claim described in this Section 7.03 (other
than any claim involving potential criminal liability) without the prior written
consent of the Lessee, unless such Indemnitee waives its right to be indemnified
under this Article 7 with respect to such claim or unless an Event of Default
under Section 16(a), 16(f), 16(g) or 16(h) of the Lease is continuing. The
Lessee shall not enter into any settlement or compromise with respect to which
the Lessee has not agreed to indemnify such Indemnitee to such Indemnitee's
satisfaction or which admits any criminal violation, gross negligence or willful
misconduct on the part of any Indemnitee without the prior written consent of
such Indemnitee.

          Section 7.04. INSURED CLAIMS. Notwithstanding any other provision of
this Article 7 to the contrary, in the case of any claim indemnified by the
Lessee hereunder which is covered by a policy of insurance maintained by the
Lessee pursuant to Section 9 of the Lease or

                                       39
<Page>

otherwise, it shall be a condition of such indemnity with respect to any
particular Indemnitee that such Indemnitee shall cooperate with the insurers in
the exercise of their rights to investigate, defend or compromise such claim as
may be required to retain the benefits of such insurance with respect to such
claim.

          Section 7.05. SUBROGATION. To the extent that an Expense indemnified
by the Lessee under this Article 7 is in fact paid in full by the Lessee and/or
an insurer under a policy of insurance maintained by the Lessee, the Lessee
and/or such insurer as the case may be shall be subrogated to the extent of such
payment to the rights and remedies of the Indemnitee on whose behalf such
Expense was paid with respect to the transaction or event giving rise to such
Expense (other than the rights and remedies in respect of insurance policies
maintained by such Indemnitee and other than the rights of the Trust Company or
the Owner Trustee and remedies against the Owner Participant under the Trust
Agreement). Should an Indemnitee receive any refund, in whole or in part, with
respect to any Expense paid in full by the Lessee hereunder, it shall promptly
pay over the amount refunded (but not an amount in excess of the amount Lessee
and/or such insurer has paid to such Indemnitee in respect of such Expense) to
the Lessee unless a Specified Default or an Event of Default shall have occurred
and be continuing (or would have occurred and be continuing if the Owner
Participant had given the notice specified in Section 16(a) of the Lease), in
which case, provided that Lessee shall have paid such Indemnitee all amounts
required under this Article 7 or under any other Operative Agreement, such
amounts shall be paid over to Owner Trustee to hold as security for Lessee's
obligations under the Lessee Documents or, if requested by Lessee, applied to
satisfy such obligations.

          Section 7.06. INFORMATION. Subject to Section 7.04, Lessee will
provide the relevant Indemnitee with such information, not within the control of
such Indemnitee, as is in Lessee's control or is reasonably available to Lessee,
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 7.03 and to control or participate in any proceeding to the extent
permitted by Section 7.03. The Indemnitee shall supply Lessee with such
information, not within the control of Lessee, as is in such Indemnitee's
control or is reasonably available to such Indemnitee, which Lessee may
reasonably request to control or participate in any proceeding to the extent
permitted by Section 7.03.

          Section 7.07. SURVIVAL OF OBLIGATIONS. The indemnities and agreements
of the Lessee provided for in this Article 7 shall survive the expiration or
other termination of this Agreement.

          Section 7.08. EFFECT OF OTHER INDEMNITIES. The Lessee's obligations
under this Article 7 shall be those of a primary obligor whether or not the
Person indemnified shall also be indemnified with respect to the same matter
under the terms of this Agreement, or any other document or instrument, and the
Person seeking indemnification from the Lessee pursuant to any provision of this
Agreement may proceed directly against the Lessee without first seeking to
enforce any other right of indemnification.

          Section 7.09. WAIVER OF CERTAIN CLAIMS. The Lessee hereby waives and
releases any Expense now or hereafter existing against any Indemnitee arising
out of death or personal injury to personnel of the Lessee, loss or damage to
property of the Lessee, or the loss of use of

                                       40
<Page>

any property of the Lessee, which results from or arises out of the condition,
use or operation of the Aircraft during the Term, including, without limitation,
any latent or patent defect whether or not discoverable.

          Section 7.10. CERTAIN LIMITATIONS. The Lessee does not guarantee and
nothing in the general indemnification provisions of this Article 7 shall be
construed as a guarantee (or an indemnification) by the Lessee with respect to
the residual value of the Aircraft or any part thereof.

                                   ARTICLE 8.
                                TRANSACTION COSTS

          Section 8.01. TRANSACTION COSTS AND OTHER COSTS.

          (a) TRANSACTION COSTS. If the transactions contemplated by this
Agreement to occur on the Delivery Date are consummated, the Owner
Participant shall pay (or reimburse the Lessee if the Lessee shall have
previously made such payment) all fees and expenses of the following persons
relating to the transactions contemplated hereby up to an aggregate maximum
amount of [*] following receipt by the Owner Participant of appropriate
invoices with respect thereto: (i) the reasonable fees and expenses of
counsel for Owner Participant; (ii) the reasonable fees and expenses of the
respective counsel for the Lessee, the Owner Trustee, the Manufacturer, the
Engine Manufacturer and the Seller; (iii) the reasonable fees and expenses of
special aviation counsel; (iv) the initial fees and expenses of the Owner
Trustee; (v) the fees and expenses of Seabury Securities, LLC (the "Lessee
Advisor"); (vi) any amounts paid in connection with any appraisal report
prepared for the Owner Participant; and (vii) any other amounts approved by
the Lessee and the Owner Participant. The fees and expenses described in
clauses (ii) through (v) of this paragraph shall be allocable to the Owner
Participant under this Agreement in such manner as is agreed to by the Owner
Participant and the Lessee.

          (b) CONTINUING EXPENSES. The Lessee agrees to pay, as Supplemental
Rent, the continuing fees, expenses and disbursements (including reasonable
counsel fees and expenses) of Trust Company and the Owner Trustee, with respect
to the administration of the Lease and the Lessor's Estate.

          (c) AMENDMENTS AND SUPPLEMENTS. Without limitation of the foregoing,
the Lessee agrees to pay, as Supplemental Rent, to the Owner Trustee and the
Owner Participant all costs and expenses (including reasonable legal fees and
expenses) incurred by any of them in connection with any amendment, supplement,
waiver or consent (whether or not entered into) under this Agreement or any
other Operative Agreement or document or instrument delivered pursuant to any of
them, which amendment, supplement, waiver or consent is required by any
provision of any Operative Agreement (including any adjustment pursuant to
Section 3(d) of the Lease) or is requested by the Lessee or necessitated by the
action or inaction of the Lessee; PROVIDED, HOWEVER, that the Lessee shall not
be responsible for fees or expenses incurred in connection with the offer, sale
or other transfer (whether pursuant to Section 5.01(c) hereof or otherwise) by
the Owner Participant or the Owner Trustee of any interest in the Aircraft, the
Lessor's Estate, the Beneficial Interest or the Trust Agreement or any similar
interest (and the

-----------

<Page>

offeror, seller, or transferor shall be responsible for all such fees and
expenses), unless such offer, sale or transfer shall occur (A) pursuant to the
exercise of remedies under Section 17 of the Lease, or (B) in connection with
the termination of the Lease or action or direction of the Lessee pursuant to
Section 8, 13 or 14 of the Lease.

                                   ARTICLE 9.

          Section 9.01. APPOINTMENT OF SUCCESSOR OWNER TRUSTEE.

          (a) RESIGNATION AND REMOVAL. The Owner Trustee or any successor Owner

may become Owner Trustee under the Trust Agreement only in accordance with the
provisions of Section 8.01 of the Trust Agreement and the provisions of
paragraphs (b) and (c) of this Section 9.01.

          (b) CONDITIONS TO APPOINTMENT. The appointment in any manner of a
successor Owner Trustee pursuant to Section 8.01 of the Trust Agreement shall be
subject to the following conditions:

               (i) such successor Owner Trustee shall be a Citizen of the United

          Section 13.09. ASSIGNMENT.

          (a) The Owner Trustee may make a security assignment of or grant a
security interest in some or all of the Lessor's Estate ("Permitted Security
Interest"), as security for the Owner Trustee's obligations in connection with
any financing by the Owner Trustee pursuant to documents reasonably acceptable
to Lessee and otherwise in compliance with this Section 13.09, to a lender
("Lessor's Lender") which (x) shall be a bank, savings institution, finance
company, leasing company, or trust company or national banking association or
other financial institution acting for its own account or in a fiduciary
capacity as trustee or agent for other financial institutions or funds, (y)
shall not be an airline or other aircraft operator or competitor of the Lessee
in the business of air transportation or an Affiliate of any thereof; and (z)
shall not be a party to any material current or overtly threatened litigation or
arbitration (whether as plaintiff or defendant) with the Lessee or any Affiliate
of the Lessee.

          The Owner Trustee will give Lessee at least ten (10) days prior
written notice of a Permitted Security Interest and Lessee agrees to execute and
deliver in connection with any Permitted Security Interest such documents and
assurances (including an acknowledgment of the Permitted Security Interest and a
certificate as to the absence of any Default under the Lease) and to take such
further action as the Owner Trustee may reasonably request in connection with
the Permitted Security Interest. A Lessor's Lender shall be entitled to be an
Indemnitee and an Additional Insured.

          (b) In connection with a Permitted Security Interest of the Lessor's
Estate by the Owner Trustee:

               (i) as a condition precedent to such Permitted Security Interest
     becoming effective, the Owner Trustee will procure that the Lessor's Lender
     shall execute and deliver to Lessee a letter of quiet enjoyment reasonably
     acceptable to Lessee in respect of Lessee's use and possession of the
     Aircraft;

               (ii) the Owner Trustee shall reimburse to Lessee its reasonable
     out-of-pocket expenses (including reasonable legal fees and expenses)
     actually incurred in connection with any such Permitted Security Interest
     referred to in this Section 13.09,

                                       46
<Page>

     provided that such expenses are substantiated to the Owner Trustee's
     reasonable satisfaction; and

               (iii) no such Permitted Security Interest shall impair the rights
     and benefits, or increase the burdens or obligations, of Lessee hereunder
     or under the Lease, including, without limitation, obligations with respect
     to the payment of Rent or under Section 6.01 or 7.01 hereof.
