                  (a) Sale and Purchase. The Owner Trustee agrees to purchase

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 the amount
determined by multiplying Lessor's Cost by the percentage set forth opposite its
name on Schedule I (the Owner Participant's "Commitment") (i) by paying such
amount to the Owner Trustee prior to the time of closing on the Delivery Date at

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

investment by the Owner Participant in the Trust Estate. The Owner Participant
shall have no obligation to provide its Commitment after September 28, 2000.

                      ------------

causing to be paid such amount to the Owner Trustee, 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

Participant). Such funds, once so applied, shall constitute a loan to the Owner
Trustee to be evidenced by an Equipment Note substantially in the form set forth

and secured as provided in the Indenture.

                  (e) Delivery Date. The "Delivery Date" shall be the date fixed

by the Lessee in accordance with this Section 2.01(e) for the closing of the
sale, leasing and loan 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 Owner Participant's Commitment and
each Loan Participant's 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 a Participant
shall have provided the amount of its Commitment to the Owner Trustee prior to
such a postponement, the Owner Trustee shall return such amount to such
Participant by 2:00 p.m. on the scheduled Delivery Date unless such Participant
shall have agreed otherwise in writing. Absent such an agreement, in the event
that the Owner Participant's 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 two percent (2%) per annum for each day that such commitment is not

                                      -4-
<PAGE>

returned to the Owner Participant by 2:00 p.m.. The making available by the
Owner Participant of its Commitment at the closing shall be deemed a waiver of
notice of the Delivery Date by the Owner Participant and the Owner Trustee, and
the making available by the Loan Participants of their respective Commitments at
the closing shall be deemed a waiver of notice of the Delivery Date by the Loan
Participants and the Indenture Trustee.

         to be done at all times all other acts including the filing, recording
         and 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 (including the first priority duly perfected
         Lien under the Indenture) as against the Lessee or any third parties in
         such jurisdiction, and the laws of such country would give effect to
         the Owner Trustee's title to and ownership interest in the Aircraft and
         the Lien of the Indenture Trustee thereon;

                      (iv)   the obligations of the Lessee (and of the Permitted

         binding and enforceable in such country;

         Participant, the Owner Trustee, and the Indenture Trustee shall receive
         a certificate of Lessee's insurance broker to such effect;

                      (vi)   the country of such re-registration imposes
         aircraft maintenance standards approved by, or at least as stringent as
         those approved by, the FAA or the central civil aviation authority of
         the United Kingdom, France, Germany, Japan, the Netherlands or Canada;

                      (vii)  it shall not be necessary by reason of such
         re-registration or for purposes of exercising rights or enforcing
         remedies contained in the Lease or the Indenture or the related
         Sublease or other Operative Agreements for the Owner Trustee, the
         Indenture Trustee or the Owner Participant to register or qualify to do
         business in such country;

                      (viii) no Liens (except Permitted Liens) shall arise by
         reason of such re-registration, and the Indenture shall continue as a
         first priority Lien on the collateral thereunder (subject only to
         Permitted Liens);

                      (ix)   none of the Owner Trustee, the Indenture Trustee
         and the Owner Participant shall be subjected to any risk of adverse tax
         consequences as a result of such re-registration for which the Lessee
         does not then indemnify or cause to be indemnified such Person in a
         manner satisfactory in form and substance to such Person;

                      (x)    any export licenses and certificate of
         deregistration required in connection with any repossession or return
         of the Aircraft will be readily obtainable in the normal course without
         material delay or material burden on the Owner Trustee, the Indenture
         Trustee or the Owner Participant, it being agreed that the Lessee shall
         be responsible for the cost thereof and (if not contrary to the
         Applicable Laws of such country) the Indenture Trustee (or, if the
         Indenture shall have been satisfied and discharged in accordance with
         its terms, the Owner Trustee) will be granted a deregistration power of
         attorney by the Lessee and the Permitted Sublessee;

                      (xi)   there is no tort liability of the owner or lessor
         of an aircraft not in possession thereof under the laws of such
         jurisdiction more 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 insurance reasonably satisfactory to the
         Owner Participant is provided to cover such risk);

                      (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 the normal course without material
         delay or material burden on the Owner Participant) for the taking or
         requisition by such government of such use or title;

                      (xiii) the courts of such proposed country of registry
         will respect the choice of New York law to govern the Lease;

                      (xiv)  such re-registration may not be affected until
         after the Recovery Period unless the Lessee prepays on a lump sum basis
         any liability due under the Tax Indemnity Agreement as a result of such
         re-registration;;

                      (xv)   there exist no possessory rights in favor of the
         Lessee (or any Permitted Sublessee) under the laws of such Permitted
         Sublessee's country of domicile that would, upon bankruptcy or
         insolvency of or other default by the Lessee and assuming that at such
         time such Permitted Sublessee is not insolvent or bankrupt, prevent the
         return or repossession of the Aircraft in accordance with and when
         permitted by the terms of Section

                                      -18-

         (ix), (x), (xi), (xii), (xiii) and (xv) of this Section 4.02(b);

                      (xvii)  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

                      (xviii) Lessee shall deliver such request to Lessor and
         Owner Participant in writing at least 20 days in advance of the date of

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 (x) no Event of Default of the type described in Section 16(a),
(f), (g) or (h) of the Lease shall have occurred and be continuing, (y) no Event
of Default shall arise as a result of such merger, consolidation, purchase,
conveyance, transfer, lease or other disposition and (z) 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)

and the Indenture Trustee immediately prior to such transaction shall

                                      -19-
<PAGE>

not be adversely affected as a result of such transaction, (v) if not the
Lessee, executes a duly authorized, legal, valid, binding, and enforceable
agreement, reasonably satisfactory in form and substance to Owner Trustee, Owner
Participant and Indenture Trustee, containing an effective assumption of all of
the Lessee's obligations hereunder and under the other Operative Agreements, and
each other document contemplated hereby or thereby and delivers such instrument
to the Indenture Trustee, the Owner Participant and the Owner Trustee, (vi)
provides an opinion from counsel (which counsel may be the Lessee's General
Counsel) delivered to the Owner Trustee, the Indenture Trustee and the Owner
Participant, which opinion shall be reasonably satisfactory to the Owner
Participant and the Indenture Trustee, and an officer's certificate (which may
rely, as to legal matters, on such legal opinion), each stating that such
merger, consolidation, conveyance, transfer, lease or other disposition and the
instrument noted in clause (v) above comply with this Section 4.02(e), that such

Person, and that all conditions precedent herein provided for relating to such
transaction have been complied with, and (vii) such survivor or Person makes

                  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

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 liability hereunder or under
the other Operative Agreements. Nothing contained herein shall permit any lease,
sublease, or other arrangement for the use, operation or possession of the
Aircraft except in compliance with the applicable provisions of the Lease.

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, the Owner Trustee, the Indenture Trustee and the
Pass-Through 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 the Indenture Estate or any interest in any thereof or
otherwise materially adversely affect the validity or priority of the Lien of
the Indenture.

                 (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 and the
          --------
Indenture Trustee 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 and Indenture Trustee) 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 transferee to acquire the Beneficial Interest do not
constitute the assets of an ERISA Plan, (v) at or prior to the time of such
transfer, the transferee shall furnish an opinion of counsel substantially in
the form attached hereto as Exhibit B-3 (or otherwise in form and substance
reasonably satisfactory to Lessee and Indenture Trustee) (which counsel may be
in-house counsel) to the effect that such transferee and any guarantor of the
payment

                                      -24-
<PAGE>

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 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 or by any foreign jurisdiction on the interest
on the Equipment Notes or the Pass-Through Certificates, in each case assuming
that the Lessee and the Holders of the Equipment Notes and the Pass-Through
Certificates are U.S. Persons. 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

(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, the Owner Trustee and the
Indenture 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, Owner Trustee and Indenture
Trustee, it being acknowledged that by acceptance of the Owner Participant
Guaranty on the Delivery Date, the Lessee is not acknowledging that the form of
such Owner Participant Guaranty is acceptable if delivered by any party other
than the original Owner Participant Guarantor who executed and delivered such
Owner Participant Guaranty on the Delivery Date), 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 such net worth requirement), (b) be legally capable of binding
itself to the obligations of the Owner Participant and (c) provide
representations and warranties substantially similar to those contained in
Section 5.01(a); 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
                               -------- -------

                                      -25-
<PAGE>

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 Indenture Trustee, 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 in accordance with the provisions of
this Section 5.01(c), 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 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, Indenture Trustee, any Holder 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, the Pass-Through Trustee, the Indenture Trustee 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

                                      -26-
<PAGE>

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, the Owner Trustee,
the Pass-Through Trustee and the Indenture 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, this Agreement and the other
Operative Agreements to which the Owner Participant is a party, 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.

         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 Indenture Trustee 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, the Indenture Trustee or the Owner
Participant that such lack of United States citizenship would have any adverse
effect on the Lessee, the Indenture Trustee, the Holders 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.

in its individual capacity represents on the Delivery Date as follows:

                      (i)    it is a state-chartered commercial bank duly
         organized and validly existing in good standing under the laws of the
         State of Maryland and has the corporate power and authority to enter

         of, or constitute any default under, its articles of incorporation or
         by-laws;

         executed and delivered by it and, assuming that each such agreement is
         the legal, valid and binding obligation of each other party thereto, is
         (or will be, as the case may be), the legal, valid and binding
         obligation of the Indenture Trustee, enforceable against the Indenture
         Trustee in accordance with its terms except as such enforceability may

and that it will at its own expense take such action as may be necessary to duly
discharge and satisfy in full, promptly, and in any event within 30 days, after
the same shall first become known to it, any Indenture Trustee's Liens.

                 (c) Indemnity for Indenture Trustee's Liens. The Indenture
                     ---------------------------------------
Trustee, in its individual capacity, agrees to indemnify and hold harmless the

Trust Estate or the Indenture Estate and any interference with the possession,
operation or other use of all or any part of the Aircraft) which may be suffered
by the Lessee, the Indenture Trustee, the Owner Participant, the Owner Trustee
or the Pass-Through Trustee as a result of the failure of the Indenture Trustee
to discharge and satisfy any Indenture Trustee's Liens attributable to it in its
individual capacity, as described in Section 5.04(b) hereof.

         Section 5.05. Indenture Trustee's Notice of Default. The Indenture

         Section 5.08.   Pass-Through Trustee's Representations and Warranties.
                         -----------------------------------------------------
The Pass-Through Trustee, in its individual capacity (except with respect to
clause (iii) below), represents and warrants as of the Delivery Date that:

                      (i)    it is a state-chartered commercial bank duly
         organized and validly existing in good standing under the laws of the
         State of Maryland and has full corporate power and authority to enter
         into and perform its obligations under the Pass-Through Trust
         Agreements, the Intercreditor Agreement and this Agreement and to
         execute and authenticate the Pass- Through Certificates to be delivered
         on the Pass-Through Closing Date;

                      (ii)   the execution, delivery and performance of this
         Agreement, and the Pass-Through Trust Agreement and the performance of
         its obligations hereunder and thereunder have been fully authorized by
         all necessary corporate action on its part, and neither the execution
         and delivery thereof nor its performance of any of the terms and
         provisions thereof will violate any federal or Maryland law or
         regulation relating to its banking or trust powers or contravene or
         result in any breach of, or constitute any default under its articles
         of incorporation, or bylaws or the provisions of any indenture,
         mortgage, contract or other agreement to which it is a party or by
         which it or its properties may be bound or affected;

                      (iii)  each of this Agreement and the Pass-Through Trust
         Agreement has been duly executed and delivered by it (in its individual
         and trust capacities) and, assuming that each such agreement is the
         legal, valid and binding obligation of each other party thereto, is or
         will be, as the case may be, the legal, valid and binding obligation of
         the Pass-Through Trustee (in its individual and trust capacities),
         enforceable in accordance with its respective terms except as limited
         by bankruptcy, insolvency, moratorium, reorganization or other similar
         laws or equitable principles of general application to or affecting the
         enforcement of creditors' rights generally (regardless of whether such
         enforceability is considered in a proceeding in equity or at law); and

                      (iv)   there are no Taxes payable by the Pass-Through
         Trustee imposed by the State of Maryland or any political subdivision
         or taxing authority thereof in connection with the execution, delivery
         and performance by the Pass-Through Trustee of this Agreement, any of
         the Pass-Through Trust Agreements (other than franchise or other taxes
         based on or measured by any fees or compensation received by the Pass-
         Through Trustee for services rendered in connection with the
         transactions contemplated by the Pass-Through Trust Agreements), and
         there are no Taxes payable by the Pass-Through Trustee imposed by the
         State of Maryland or any political subdivision thereof in connection
         with the acquisition, possession or ownership by the Pass-Through
         Trustee of any of the Equipment Notes other than franchise or other
         taxes based on or measured by any fees or compensation received by the
         Pass-Through Trustee for services rendered in connection with the
         transactions contemplated by the Pass-Through Trust Agreements and,
         assuming that the trusts created by the Pass-Through Trust Agreements
         will not be classified as an association or a publicly traded
         partnership taxable as a corporation for federal income tax purposes,
         and assuming

                                      -33-
<PAGE>

         that the assets of the trusts will be treated as held for investment
         purposes as provided in each Pass-Through Trust Agreement, such trusts
         will not be subject to any taxes (including, without limitation, net or
         gross income, tangible or intangible property, net worth, capital,
         franchise or doing business tax), fee or other governmental charge
         under the laws of the State of Maryland or any political subdivision
         thereof.

Trustee (in its individual or trust capacity), the Pass-Through Trustee (in its
individual or trust capacity), the Indenture Trustee (in its individual or trust
capacity) and the Subordination Agent (in its individual or trust capacity)
provided for in this Article 5, and their respective obligations under any and
all of them, shall survive the delivery of the Aircraft and the expiration or
other termination of this Agreement and the other Operative Agreements.

         Section 5.10. Lessee's Assumption of the Equipment Notes.
                       ------------------------------------------

                 (a)   Subject to compliance by the Lessee with all of its
obligations under the Operative Agreements, each of the Owner Participant, the
Owner Trustee, the Indenture Trustee, the Pass-Through Trustee and the Lessee
covenants and agrees that if the Lessee elects to purchase the Aircraft on the
EBO Date pursuant to Section 13(b) of the Lease, if no Event of Default shall
exist, then, upon compliance with the applicable provisions of the Operative
Agreements, the Owner Trustee will transfer to the Lessee, without recourse or
warranty (except as to the absence of Lessor's Liens attributable to the Owner
Trustee) but subject to the Lien of the Indenture, all of the Owner Trustee's
right, title and interest in and to the Aircraft, and if the Lessee, in
connection with such purchase, elects to assume the obligations of the Owner
Trustee to the Indenture Trustee and the Holders under the Indenture, the
Equipment Notes, and hereunder, the Lessee shall so notify the Indenture Trustee
(such notice to be given at least 30 and not more than 60 days prior to the
effective date of such assumption), and each of the parties shall execute and
deliver appropriate documentation permitting the Lessee to assume such
obligations on the basis of full recourse to the Lessee, maintaining for the
benefit of the Holders the security interest in the Aircraft created by the
Indenture, and upon compliance with the provisions of this Section 5.10
releasing the Owner Participant and the Owner Trustee from all obligations in
respect of the Equipment Notes, the Indenture, this Agreement, and the other
Operative Agreements, except any obligations relating to the period prior to
such assumption and take all such other actions, at the Lessee's expense, as are
reasonably necessary to permit such assumption by the Lessee.

                 (b)   In connection with such assumption:

                   (i) the Lessee shall execute and deliver an instrument (A)
         pursuant to which the Lessee irrevocably and unconditionally assumes
         and undertakes, with full recourse to the Lessee, to pay, satisfy, and
         discharge when and as due (at the stated maturity thereof, by
         acceleration or otherwise) the principal of, Make-Whole Premium, if
         any, interest, and all other sums owing on all Outstanding Equipment
         Notes (or on the Lessee's substituted

                                      -34-
<PAGE>

         obligations) in accordance with their terms, and punctually to perform
         and observe all of the covenants and obligations hereunder and under
         the Indenture and the Equipment Notes (as the same may be amended in
         connection with such assumption) to be performed or observed by the
         Owner Trustee, and (B) which contains amendments to the Indenture, in
         form and substance as reasonably satisfactory to the Indenture Trustee,
         that incorporate therein such provisions from the Lease and this
         Agreement as may be appropriate, including, without limitation, events
         of default substantially identical in scope and effect to those set
         forth in the Lease and covenants substantially identical to the
         covenants of the Lessee hereunder and under the Lease;

                      (ii)   the instrument referred to in paragraph (i) of this
         Section 5.10(b), any Uniform Commercial Code financing statements
         relating thereto, and any other documents which shall be necessary (or
         reasonably requested by the Indenture Trustee) to establish the
         Lessee's title to and interest in the Aircraft or to reflect the
         substitution of the Lessee for the Owner Trustee under the Operative
         Agreements or to continue the perfection of the security interests in
         the Aircraft and the other rights, property, and interests included in
         the Indenture Estate for the benefit of the Holders shall be filed in
         such form, manner, and places as are necessary or, in the reasonable
         opinion of the Indenture Trustee, advisable for such purpose;

                      (iii)  the Indenture Trustee shall have received an
         insurance report dated the effective date of such assumption of an
         independent insurance broker and certificates of insurance, each in
         form and substance satisfactory to the Indenture Trustee, as to the due
         compliance as of the effective date of such assumption with the terms
         of Section 9 of the Lease (as it relates to the Indenture Trustee)
         relating to the insurance with respect to the Aircraft (provided that
                                                                 --------
         the required amount of all-risk hull insurance, subject to the self
         insurance rights of the Lessee, shall be in an amount at least equal to
         the aggregate outstanding amount of the Equipment Notes plus six months
         interest);

                      (iv)   the Indenture Trustee shall have received a
         certificate from the Lessee that no Specified Default exists as of the
         effective date of such assumption;

                      (v)    the Indenture Trustee shall have received (A) from
         counsel for the Lessee (who may be the Lessee's General Counsel) a
         legal opinion, in form and substance as reasonably satisfactory to the
         Indenture Trustee: (w) with respect to the compliance of the assumption
         contemplated hereby with the terms hereof, (x) with respect to the due
         authorization, execution, delivery, validity, and enforceability of the
         instrument referred to in paragraph (i) of this Section 5.10(b), (y)
         with respect to the continued perfection of the security interest in

         the continued availability of the benefits of Section 1110 to the
         Indenture Trustee for the benefit of the Holders with respect to the
         Aircraft after giving effect to such assumption (but only to the extent
         such benefits would have been available to the Holders prior to such
         assumption assuming compliance with the Operative Agreements by the
         parties thereto), (B) from counsel to the Indenture Trustee and
         Lessee's special aviation counsel, a legal opinion

                                      -35-
<PAGE>

         comparable to the respective opinions delivered on the Delivery Date,
         as the case may be, with such changes therein as may be appropriate in
         light of such assumption, and (C) in the case of each opinion described
         in clause (A) or (B) above, covering such additional matters as the
         Indenture Trustee shall reasonably request; and

                      (vi) the Lessee shall (i) obtain a written confirmation
         from each Rating Agency that such assumption will not result in a
         withdrawal, suspension or downgrading of the ratings of any class of
         Pass-Through Certificates, (ii) provides the Indenture Trustee with an
         opinion of counsel (both counsel and opinion reasonably satisfactory to
         the Indenture Trustee) that the Pass-Through Trusts will not be subject
         to U.S. federal income tax as a result of such assumption and (iii)
         furnishes to the Indenture Trustee either (A) an opinion of counsel
         (both counsel and opinion reasonably satisfactory to the Indenture
         Trustee) that the holders of the Pass-Through Certificates will not
         recognize gain or loss for U.S. federal income tax purposes and will be
         subject to U.S. federal income tax on the same amount and in the same
         manner and at the same time as would have been the case if such
         assumption had not occurred or (B) both an opinion of counsel (both
         counsel and opinion reasonably satisfactory to the Indenture Trustee)
         that the holders of the Pass-Through Certificates should not recognize
         gain or loss for U.S. federal income tax purposes in connection with
         such assumption and should be subject to U.S. federal income tax on the
         same amount and in the same manner and at the same time as would have
         been the case if such assumption had not occurred and an indemnity in
         favor of the holders of the Pass-Through Certificates in form and
         substance reasonably satisfactory to the Indenture Trustee.

               (c) The Lessee shall pay all reasonable expenses (including
reasonable fees and expenses of counsel) of the Indenture Trustee, the Owner
Trustee, the Pass-Through Trustee, each Liquidity Provider and the Owner
Participant in connection with such assumption.

         Section 5.11.    Compliance with Trust Agreement, Etc. Each of the
                          ------------------------------------
Owner Participant, Trust Company, and the Owner Trustee agrees with the Lessee,
the Indenture Trustee, the Liquidity Providers and the Pass-Through Trustee that
so long as the Lien of the Indenture shall be in effect it will (i) comply with
all of the terms of the Trust Agreement applicable to it in its respective
capacity, the noncompliance with which would materially adversely affect any
such party and (ii) not take any action, or cause any action to be taken, to
amend, modify or supplement any other provision of the Trust Agreement in a
manner that would materially adversely affect any such party without the prior
written consent of such party. The Owner Trustee confirms for the benefit of the
Lessee, the Indenture Trustee, the Liquidity Providers and the Pass-Through
Trustee that it will comply with the provisions of Article 2 of the Trust
Agreement. Notwithstanding anything else to the contrary in the Trust Agreement,
so long as the Lease remains in effect, the Owner Participant agrees not to
terminate or revoke the trust created by the Trust Agreement without the consent
of the Lessee. If and so long as the Indenture shall not have been discharged
the consent of the Indenture Trustee shall also be required prior to any
termination or revocation of such trust and in addition, the Owner Trustee will,
at the Lessee's expense, promptly and duly execute and deliver to the Indenture
Trustee such documents and assurances including, without limitation,
conveyances, financing statements and

                                      -36-

continuation statements with respect to financing statements and take such
further action as the Indenture Trustee may from time to time reasonably request
in order to protect the rights and remedies created or intended to be created in
favor of the Indenture Trustee under the Indenture and to create for the benefit
of the Holders a valid first priority Lien with respect to, and a first and
prior perfected security interest in, the Indenture Estate.

Agent represents and warrants as of the Delivery Date, that:

                    (i)   it is a state-chartered commercial bank duly organized

         Agreement and the performance of its obligations hereunder and
         thereunder have been fully authorized by all necessary, corporate
         action on its part, and, neither the execution and delivery thereof nor
         its performance of any of the terms and provisions thereof will violate
         any federal or Maryland law or regulation relating to its banking or
         trust powers or contravene or result in any breach of, or constitute
         any default under its articles of incorporation, or bylaws or the
         provisions of any indenture, mortgage, contract or other agreement to
         which it is a party or by which it or its properties may be bound or
         affected;

                    (iii) each of this Agreement, the Liquidity Facilities and
         the Intercreditor Agreement has been duly executed and delivered by it
         and, assuming that each such agreement is the legal, valid and binding
         obligation of each other party thereto, is or will be, as the case may
         be, the legal, valid and binding obligation of the Subordination Agent,
         enforceable in accordance with its respective terms except as limited
         by bankruptcy, insolvency, moratorium, reorganization or other similar
         laws or equitable principles of general application to or affecting the
         enforcement of creditors' rights generally (regardless of whether such
         enforceability is considered in a proceeding in equity or at law);

                    (iv)  there are no Taxes payable by the Subordination Agent
         imposed by the State of Maryland or any political subdivision or taxing

         or other taxes based on or measured by any fees or compensation
         received by the Subordination Agent for services rendered in connection
         with the transactions contemplated by the Intercreditor Agreement or
         any of the Liquidity Facilities);

                      (v)    to the best of the Subordination Agent's knowledge,
         there are no pending or threatened actions or proceedings against the
         Subordination Agent before any court or administrative agency which
         individually or in the aggregate, if determined adversely to it, would
         materially adversely affect the ability of the Subordination Agent to
         perform its obligations under this Agreement, the Intercreditor
         Agreement or any Liquidity Facility;

                      (vi)   the Subordination Agent has not directly or
         indirectly offered any Equipment Note for sale to any Person or
         solicited any offer to acquire any Equipment Notes from any Person, nor

         offer directly or indirectly any Equipment Note for sale to any Person,
         or to solicit any offer to acquire any Equipment Note from any Person;
         and the Subordination Agent is not in default under any Liquidity

supplement would have the effect of limiting any right or of increasing any
obligation or liability of the Lessee under the terms of the Lease or any other

         Purchase Price;

                   (x)     Any Taxes imposed on the Owner Trustee or Owner

         or any Taxes imposed on the Indenture Trustee which would not have been
         imposed but for an Indenture Trustee's Lien;

                   (xi)    In the case of the Owner Participant, any Taxes
         relating to, resulting from, arising out of or in connection with a
         "prohibited transaction" within the meaning of Section 406 of ERISA or

         Owner Participant, taxes in the nature of an intangible or similar Tax
         imposed on or with respect to the Equipment Notes (or the indebtedness
         evidenced thereby), the Pass-Through Certificates, the Trust Estate or
         the Trust Agreement;

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

                   (xv)    United States withholding Taxes imposed on an Owner
         Participant as a result of such Owner Participant not being a U.S.
         Person; or

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

                 (c)       Withholding. The Pass-Through Trustee shall withhold
                           -----------
any Taxes required by law to be withheld on payments to any holder of a Pass-
Through Certificate. The Indenture Trustee shall withhold any Taxes required to
be withheld on any payment to a Holder pursuant to Section 5.09 of the
Indenture. If the Indenture Trustee or the Pass-Through Trustee fails to
withhold a Tax required to be withheld with respect to any Holder of an
Equipment Note or any holder of a Pass-Through Certificate or any claim is
otherwise asserted by a taxing authority against the Owner Trustee or Owner
Participant for any withholding tax, unless the Owner Participant is an entity

                                      -42-
<PAGE>

described in Section 6.13 the Lessee will indemnify the Owner Trustee and the
Owner Participant (without regard to the exclusions set forth in Section 6.01(b)
hereof) on an After-Tax Basis against any such Taxes required to be withheld and
any interest and penalties with respect thereto, along with any other costs
(including reasonable attorney's fees) incurred in connection with any such
claim. The Indenture Trustee or the Pass-Through Trustee, as the case may be, in
its individual capacity (and without recourse to the Indenture Estate), shall
indemnify the Lessee (without regard to the exclusions set forth in Section
6.01(b) hereof) on an After-Tax Basis for any payment the Lessee shall have made
pursuant to the preceding sentence.

          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),
(x), (xi), (xii), (xiii), (xiv) and (xv) 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

                                      -43-
<PAGE>

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 Participation
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
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 effectively precluded 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
                           -------------------
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 (as confirmed in writing by such Tax Indemnitee) 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

                                      -44-
<PAGE>

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 the 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 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 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 or payment, (E)
Lessee shall have acknowledged its liability for such claims, and (F) 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; provided,
                                                                 --------
further, that if the contest is being conducted in the name of the Owner
-------
Participant, the Lessee shall not be permitted to appeal any adverse decision to
the United States Supreme Court in the name of the Owner Participant without the
written consent of the Owner Participant.

                 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 with respect to which the requirements to constitute a Lessee
Controlled Contest are not satisfied), 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

                                      -45-
<PAGE>

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 provided a bond or other
         sufficient protection against any such risk 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

                                      -46-
<PAGE>

Court and 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 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 Impaired. 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 effectively precluded and (C) the Lessee
furnishes, at the Lessee's

                                      -47-
<PAGE>

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 effectively precluded, 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 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), (x), (xi), (xii), (xiii), (xiv) and
(xv) 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 Tax 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 required to be 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

                                      -48-
<PAGE>

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 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 or
the 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, (y) Lessee
or the Indenture Trustee 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

                                      -49-
<PAGE>

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.

         Section 6.13. Non-U.S. Owner Participant. If an Owner Participant is a
                       --------------------------
Non-U.S. Person or is incorporated or organized in a country other than the
United States or in a territory, possession or commonwealth of the United States
(within the meaning of the tax law of that foreign jurisdiction) and if as a
result thereof any withholding taxes are imposed by the United States with
respect to payments of Rent or any foreign withholding Taxes are imposed on any
payments to any Noteholder, then Owner Participant shall indemnify and hold
harmless on an After-Tax Basis the Lessee and each Tax Indemnitee from any
adverse consequences resulting from such withholding or withholding
requirements.

                                  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 (including strict or absolute liability without
fault in tort or otherwise), obligations, losses, damages, settlements,
penalties, fines, claims, actions, suits, costs, disbursements and expenses,
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:

         with the terms of the Lease, including, without limitation, claims for

         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;

         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 any Pass-Through Trust Agreement, or the
         falsity or inaccuracy of any representation or warranty of the Lessee
         in any of the Operative Agreements or any Pass-Through Trust Agreement
         (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));

                      (vi)   the offer, issuance, sale or delivery of any
         Equipment Note, any Pass-Through Certificate (or any certificates or
         securities issued in connection with any refinancing thereof pursuant
         to Article 13 hereof) or 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

                                      -51-

         Note or any holder's interest in any Pass- Through Certificate.

           (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

         any representation or warranty or by any failure of Lessee to perform

         any similar interest (including an offer or sale resulting from
         bankruptcy or other proceedings for the relief of debtors in which such

         occur (a) pursuant to the exercise of remedies under Section 17 of the
         Lease or (b) pursuant to Section 5(b), 7(b), 7(d), 7(e), 8, 12(b),

         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

         made pursuant to the terms of any of the Operative Agreements or Pass-
         Through Documents;

             (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

                                      -53-
<PAGE>

failure adversely affects any applicable defense or counterclaim, otherwise
increases the amount the Lessee would have been liable for in the 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, at Lessee's expense, with all reasonable requests of
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, the Indenture
Estate 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.
Nothing contained in this Article 7 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. 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,

                                      -54-
<PAGE>

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 Expense indemnified by the
Lessee hereunder which is covered by a policy of insurance maintained by the
Lessee (or a Permitted Sublessee) pursuant to Section 9 of the Lease or
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, so long as no Specified Default or Event
of Default has occurred and is continuing, 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 (except under insurance
policies paid for by such Indemnitee), 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 (or, so long as the Indenture shall not have been
discharged, to the Indenture 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 and the other Operative Agreements.

         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 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 (i) that the
principal of, premium, if any, or interest on any "Equipment Note" (as defined
in the Pass-Through Trust Agreements) will be paid or (ii) with respect to the
residual value of the Aircraft or any part thereof.

         Section 7.11. Certain Transfers. If the Owner Participant (i) makes any
                       -----------------
claim for payment as a result of the indemnity provided by the Lessee in Section
6.01(a)(x) or 7.01(a)(vii), and (ii) such claim is the result of the direct or
indirect acquisition or holding of a Pass-Through Certificate by an ERISA Plan,
established or maintained by Owner Participant or any entity that is treated as
a single employer with Owner Participant under Section 414(b), (c), (m) or (o)
of the Code (an "ERISA Affiliate") or as to which Owner Participant or any ERISA
Affiliate of Owner Participant contributed or is a member, the Lessee shall have
the right, upon 30 days notice to the Owner Participant, to purchase the
Beneficial Interest, on a Termination Date specified in such notice, for a price
equal to the higher of (1) the Owner Participant's Share of Termination Value
and (2) the Owner Participant's Share of FMV. In connection with any such
purchase, the Lessee shall (i) obtain a written confirmation from each Rating
Agency that such purchase will not result in a withdrawal, suspension or
downgrading of the ratings of any class of Pass-Through Certificates and (ii)
pay all unpaid Supplemental Rent (including payment of such indemnity claim) due
on or before such Termination Date. The Lessee shall not have the right to
purchase the Beneficial Interest in any instance pursuant to the foregoing
sentence in the event the Owner Participant waives any claim for payment it may
have in such instance pursuant to clause (i) above. For purposes of this Section
7.11, "Owner Participant's Share of Termination Value" means the excess of (w)
the Termination Value as of such Termination Date, over (x) the aggregate
principal amount of Equipment Notes that would be outstanding on such
Termination Date (and accrued interest thereon at the Debt Rate) assuming all
payments of Basic Rent payable on or prior to such Termination Date shall have
been paid when due, and "Owner Participant's Share of FMV" means the Fair Market
Sales Value of the Aircraft as of such Termination Date, determined in
accordance with the definition thereof but assuming (y) that the Aircraft is
subject to the Lease, the Indenture, the indebtedness evidenced by the Equipment
Notes and the other Operative Agreements and (z) that the violation giving rise
to such indemnity claim has been cured. Nothing in this Section 7.11 shall
affect the obligation of the Lessee to make

                                      -56-
<PAGE>

any payment of Supplemental Rent or Basic Rent due on or prior to such
Termination Date, the payment of which amount is a condition precedent to the
exercise by the Lessee of its rights under this Section 7.11; provided that, the
                                                              -------- ----
portion, if any, of Basic Rent payable on such Termination Date that is
specified in column (4) of Exhibit C-1 to the Lease as allocable to the
Allocation Period commencing on the day immediately following such Termination
Date shall, in connection with any purchase under this Section 7.11, be deemed
to be paid following such purchase, and accordingly the Owner Participant shall
have no interest in such portion of Basic Rent following such purchase.

                         ---------------------------------

                 (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 offering of the Pass-Through Certificates contemplated by the
Placement Agreement and related to the transactions contemplated hereby up to an
aggregate maximum amount equal to the Assumed Transaction Costs (as defined in
Exhibit B to the Lease), following receipt by the Owner Participant of

of counsel for Owner Participant; (ii) the reasonable fees and expenses of the
respective counsel for the Lessee, the Owner Trustee, the Indenture Trustee, the

Trustee, the Paying Agent, each Liquidity Provider and the Placement Agents
(other than those fees, expenses and disbursements payable by the Placement
Agent pursuant to the Placement Agreement); (iii) the reasonable fees and
expenses of special aviation counsel; (iv) any initial fees and expenses of the
Pass-Through Trustee and the initial fees and expenses of the Owner Trustee, the

LLC (the "Lessee Advisor"); (ix) any amounts paid in connection with any
appraisal report prepared for the Owner Participant; and (x) any other amounts
approved by the Lessee and the Owner Participant. To the extent Transaction
Costs exceed the Assumed Transaction Costs, the Owner Participant may elect to
have the Lessee pay the amount of such excess, and if the Owner Participant so
elects the Lessee shall pay the amount of such excess by paying those of the
costs set forth in clauses (i) through (x) as are specified by the Owner
Participant and the Owner Participant shall have no obligation to pay (or
reimburse the Lessee for) the amount of such excess.

                 (b)     Continuing Expenses. The Lessee agrees to pay, as

the case of the Pass-Through Trustee, (1) any reasonable fees, costs and

or reports, including any schedule, if any, required to be filed on any Pass-
Through Trust (other than any such fees, costs or expenses which are incurred in
the normal course of the performance of the Pass-Through Trustee's duties and
for which the Pass-Through Trustee would not otherwise seek reimbursement from
the Pass-Through Trust) and (2) any reasonable fees, costs and expenses incurred
and any penalties incurred by the Pass-Through Trustee or imposed upon a Pass-
Through Trust relating to the failure to file any such tax return unless such
failure is the result of the gross negligence or willful misconduct of the Pass-
Through Trustee and (y) in the case of the Subordination Agent, any reasonable
fees and expenses incurred in connection with the replacement of any Liquidity
Provider as provided in the Intercreditor Agreement); and (iv) the continuing
fees, expenses and disbursements (including reasonable counsel fees and

foregoing, the Lessee agrees to pay, as Supplemental Rent, to the Owner Trustee,

connection with any amendment, supplement, waiver or consent (whether or not
entered into) under this Agreement or any other Operative Agreement or document

                                  REFINANCING

         Section  13.01.   Refinancing.
                           -----------

                 (a)  Subject to the terms and conditions of this Section 13.01,
the Lessee may request the Owner Participant to participate in two refinancings
in whole but not in part, of the

                                      -61-
<PAGE>

Equipment Notes prior to the end of the Basic Term (a "Refinancing"). Such
Refinancing may be placed in either the private or public markets and shall be
denominated in Dollars and shall be on terms reasonably satisfactory to the
Owner Participant. The Owner Participant will agree to negotiate promptly in
good faith to conclude an agreement with the Lessee as to the terms of any such
Refinancing transaction (including the terms of any debt to be issued in
connection with such refinancing and the documentation to be executed in
connection therewith). Without the prior written consent of the Owner
Participant, the prospectus and other offering materials relating to any
Refinancing in the form of a public offering shall not identify the Owner
Participant and shall not include any financial statements of the Owner
Participant or any Affiliate thereof. In connection with any such Refinancing in
the form of a public offering, the Lessee shall indemnify the Owner Participant
in a manner satisfactory to it for any liabilities under federal, state or
foreign securities laws resulting from such offering. The aggregate principal
amount of the new Equipment Notes issued in connection with any Refinancing
shall be the same as the aggregate principal amount outstanding on the Equipment
Notes being refinanced.

                 (b) Notwithstanding anything herein to the contrary, no
Refinancing will be permitted unless the Owner Participant and the Indenture
Trustee shall have received at least 15 days' prior written notice of the
scheduled closing date of such Refinancing and the Owner Participant shall have
been provided such longer period as it shall have required for a reasonable
opportunity to review the relevant documentation and the Owner Participant shall
have determined in good faith that neither it nor the Owner Trustee shall suffer
any loss or expense or bear any increased risk as a result of such Refinancing
(including, without limitation, any risk with respect to taxes or other adverse
consequences to the Owner Participant including the application of Revenue
Procedures 75-21 and 75-28 and Section 467 of the Code) for which it has not
been or will not have been indemnified in a manner satisfactory in form and
substance to the Owner Participant.

                 Prior to the consummation of any Refinancing pursuant to this
Section 13.01, the Owner Participant and the Lessee shall agree upon a schedule
setting forth each installment of Basic Rent, the Basic Rent allocations, the
Termination Values payable pursuant to the Lease and the EBO Amount as a result
of the Refinancing in accordance with Section 3(d) of the Lease, and thereafter
the amounts set forth in such schedule shall become the amounts payable under
the Lease. Upon the consummation of the Refinancing, the evidence of
indebtedness issued pursuant to the Refinancing shall be considered "Equipment
Notes" for purposes of this Agreement and the Lease.

                 (c) Notwithstanding the foregoing, the Owner Participant shall
have no obligation to proceed with any Refinancing transaction as contemplated
by this Section 13.01 unless the Lessee provides an indemnity on an After Tax
Basis to the Owner Trustee and the Owner Participant by agreement in form and
substance satisfactory to each of them (provided that Taxes are excluded from
such indemnity), for any liability, obligation (other than, in the case of the
Owner Trustee, the non- recourse obligation to pay principal and interest in
respect of the refinanced indebtedness), cost or expense (including, without
limitation, reasonable attorneys' fees and Make-Whole Premium or other amounts
due under the Indenture).

                                      -62-
<PAGE>

          (d)        Without the prior written consent of the Owner Participant,
no such refinancing shall (1) cause the aggregate principal amount of the
indebtedness to be substituted for the Equipment Notes to exceed the aggregate
principal amount of the then outstanding Equipment Notes, (2) cause the weighted
average life of such indebtedness to be longer than the remaining weighted
average life of the then outstanding Equipment Notes, or (3) cause the date of
maturity of such indebtedness to be later than the date of maturity of the
Equipment Notes being refinanced.

          (e)        Subject to the foregoing provisions of this Section 13.01,
each party agrees to take or cause to be taken all requested action, including,
without limitation, the execution and delivery of any documents and instruments,
including, without limitation, amendments or supplements to the Lease, which may
be reasonably necessary or desirable to effect such Refinancing, including, in
the case of the Owner Participant, direction to the Owner Trustee by the Owner
Participant to prepay the Equipment Notes then outstanding; provided, however,
                                                            --------  -------
that such Refinancing shall be subject to the satisfaction of each of the
following conditions:

              (i)    Payment shall have been made with respect to principal,
         accrued interest, Make-Whole Premium, if any, and all other sums due
         and owing on the Equipment Notes payable under the Indenture;

              (ii)   Payment in full of all other amounts then due and
         owing by the Lessee under this Agreement, the Indenture, the Lease, the
         Trust Agreement, and the Equipment Notes then outstanding shall have
         been made by the Lessee;

              (iii)  Such party shall have received such opinions of counsel
         (including, without limitation, an opinion received by the Owner
         Participant from independent tax counsel selected by Owner Participant
         and reasonably satisfactory to the Lessee that such Refinancing shall
         not result in any, or the risk of any, adverse tax consequences to such
         Owner Participant, unless the Lessee shall have provided, or caused to
         be provided, an indemnity in respect thereof satisfactory in form and
         substance to the Owner Participant), certificates and other documents
         as it may reasonably request, each in form and substance reasonably
         satisfactory to such party;

              (iv)   All authorizations, approvals and consents which in the
         reasonable judgment of the Owner Participant are necessary for such
         Refinancing shall have been obtained;

              (v)    No Specified Default shall exist or would occur immediately
         after giving effect to such Refinancing;

              (vi)   In the event the Lessee shall not prohibit the purchase of
         the Refinancing loan certificates by, or with the assets of, an ERISA
         Plan, the Lessee will permit the placement of the Refinancing loan
         certificates with an ERISA Plan only if either (A) if such placement is
         in the form of pass-through certificates, the sole underwriter or the
         manager or co-manager of the underwriting syndicate or the selling or
         placement agent of such pass-through

                                      -63-

         certificates represents to the Lessee that it has a prohibited
         transaction exemption from the U.S. Department of Labor with respect to
         pass-through certificates (such as Prohibited Transaction Exemption 89-
         88 or any other comparable exemption) or (B) purchasers of the
         Refinancing loan certificates (or if the Refinancing involves the
         issuance and sale of pass- through certificates, purchasers of such
         pass-through certificates) provide a representation (which may be in
         the form of a deemed representation) regarding their source of funds
         used in acquiring the Refinancing loan certificates (or such pass-
         through certificates, as the case may be) and, if such purchasers
         represent that they are using funds of an ERISA Plan in acquiring the
         Refinancing loan certificates (or such pass-through certificates, as
         the case may be), such purchasers further represent that they are
         relying on a prohibited transaction exemption from the U.S. Department
         of Labor with respect to their purchase and holding of the Refinancing
         loan certificates (or such pass-through certificates, as the case may
         be). The reliance on any such exemption will not be conditional on the
         Owner Participant's representation concerning its party in interest or
         other status with respect to ERISA Plans; and

                    (vii) The Lessee shall pay all costs and expenses (including
         legal fees and disbursements) incurred in connection with any proposed
         or actually consummated Refinancing.

         Section 15.07. Certain Limitations on Reorganization. The Indenture
                        -------------------------------------
Trustee and each Holder agree that, if (i) the Owner Trustee becomes or all or
any part of the Lessor's Estate or the trust created by the Trust Agreement
becomes the property of, a debtor subject to the reorganization provisions of
the Bankruptcy Code or any other applicable bankruptcy or insolvency statutes,
(ii) pursuant to any such reorganization provisions, the Owner Participant is
held to have recourse liability to the Indenture Trustee, any Holder, the
debtor, the Owner Trustee or the trustee of the debtor directly or indirectly on
account of any amount payable as Make-Whole Premium, principal or interest on
the Equipment Notes, or any other amount payable on any Equipment Note that is
provided in the Operative Agreements to be nonrecourse to the Owner Participant

Amount which reflects any payment by the Owner Participant on account of (ii)
above, then such Holder or the Indenture Trustee, as the case may be, shall
promptly refund to the Owner Participant such Recourse Amount. For purposes of
this Section 15.07, "Recourse Amount" means the amount by which the portion of
such payment by the Owner Participant on account of clause (ii) above received
by such Holder or the Indenture Trustee exceeds the amount which would have been
received by such Holder or the Indenture Trustee if the Owner Participant had
not become subject to the recourse liability referred to in (ii) above. Nothing
contained in this Section shall prevent the Indenture Trustee from enforcing any
individual obligation (and retaining the proceeds thereof) of the Owner
Participant under this Agreement or, any other Operative Agreement to the extent
herein or therein provided, for which the Owner Participant has expressly agreed
by the terms of this Agreement to accept individual responsibility.

                        -----------------------------------------------------

          Section 6.05. Reliance Upon Certificates, Counsel and Agents. The

Owner Trustee shall incur no liability to anyone in acting in reliance upon any
signature, instrument, notice, resolution, request, consent, order, certificate,
report, opinion, bond or other document or paper reasonably believed by it to be
genuine and reasonably believed by it to be signed by the proper party or
parties. Unless other evidence in respect thereof is specifically prescribed
herein, any request, direction, order or demand of the Owner Participant, Lessee

Agreements to which the Owner Trustee is a party shall be sufficiently evidenced
by written instruments signed by a person purporting to be an officer of the

<PAGE>

Indenture Trustee, as the case may be, certified by the Secretary or an
Assistant Secretary of Lessee, the Owner Participant or the Indenture Trustee,
as the case may be, as duly adopted and in full force and effect, as conclusive
evidence that such resolution has been duly adopted by said Board and that the
same is in full force and effect. As to any fact or matter the manner of
ascertainment of which is not specifically described herein, the Owner Trustee
may, absent actual knowledge to the contrary, for all purposes hereof rely on a
certificate signed by an officer of Lessee, the Owner Participant or the
Indenture Trustee, as the case may be, as to such fact or matter, and such
certificate shall constitute full protection to the Owner 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 Owner Trustee may
exercise its powers and perform its duties hereunder directly or through agents
or attorneys and the Owner Trustee shall not be liable for the default or
misconduct of any agents or attorneys selected by it with reasonable care. In
the administration of the trusts hereunder, the Owner Trustee may consult with
counsel, accountants and other skilled persons and the Owner Trustee shall not
be liable for anything done, suffered or omitted in good faith by it in
accordance with the advice or opinion of any such counsel, accountants or other
skilled persons selected by it with reasonable care.

          Section 6.06. Not Acting in Individual Capacity. In acting hereunder,
                        ---------------------------------
the Owner Trustee acts solely as trustee and not in its individual capacity
except as otherwise expressly provided herein; and, except as may be otherwise
expressly provided in this Trust Agreement, including without limitation,
Section 6.01, the Lease, the Participation Agreement or the Indenture, all
Persons having any claim against the Owner Trustee by reason of the transactions
contemplated hereby shall look only to the Trust Estate for payment or
satisfaction thereof.

          Section 6.07. Fees; Compensation.  Except as provided in Section
                        ------------------
5.03 or 7.01, the Owner Trustee agrees that it shall have no right against the
Owner Participant or the Trust Estate for any fee as compensation for its
services hereunder.

          Section 6.08. Tax Returns. The Owner Trustee shall be responsible for
                        -----------
the keeping of all appropriate books and records relating to the receipt and
disbursement by it of all monies under this Trust Agreement or any agreement
contemplated hereby. The Owner Trustee shall be responsible for causing to be
prepared and filed, at Lessee's expense, all income tax returns required to be
filed with respect to the trust created hereby as requested by the Owner
Participant and shall execute and file such returns as directed by the Owner
Participant.

          Section 6.09. Fixed Investment Trust. Notwithstanding anything
                        ----------------------
herein to the contrary, the Owner Trustee shall not be authorized and shall have
no power to "vary the investment" of the Owner Participant within the meaning of
section 301.7701-4(c) of the Treasury Regulations.

                        ----------------------------------------------------
The Owner Participant hereby agrees, whether or not any of the transactions
contemplated hereby shall be consummated, to assume liability for, and does
hereby indemnify, protect, save, defend and hold harmless the Owner Trustee in
its individual capacity, and its successors, assigns (but not security assigns),
directors, officers, representatives, agents, employees and servants, from and
against any and all liabilities, obligations, losses, damages, penalties, taxes
(excluding any taxes payable by the Owner Trustee on or measured by any
compensation received by the Owner Trustee for its services hereunder), claims,
actions, suits, costs, expenses or disbursements (including, without limitation,
reasonable legal fees, but excluding internal costs and expenses such as
salaries and overhead) and expenses of any kind and nature whatsoever which may
be imposed on, incurred by or asserted against the Owner Trustee in its
individual capacity (whether or not also indemnified against by Lessee under the
Lease or under the Participation Agreement or also indemnified against by any
other Person; provided that Owner Participant shall be subrogated to the rights
              --------
of Owner Trustee against Lessee or any other indemnitor) in any way relating to
or arising out of this Trust Agreement or any of the other Operative Agreements
or the enforcement of any of the terms of any thereof, or in any way relating to
or arising out of the manufacture, purchase, acceptance, nonacceptance,
rejection, ownership, delivery, lease, possession, use, operation, condition,
sale, return or other disposition of the Airframe, any Engine or any Part of the
foregoing (including, without limitation, latent and other defects, whether or
not discoverable, and any claim for patent, trademark or copyright
infringement), or in any way relating to or arising out of the administration of
the Trust Estate or the action or inaction of the Owner Trustee hereunder,
except (a) in the case of willful misconduct or gross negligence on the part of
the Owner Trustee either as trustee or in its individual capacity in the
performance or nonperformance of its duties hereunder or under any of the other
Operative Agreements to which it is a party or (b) those resulting from the
inaccuracy of any representation or warranty of the Owner Trustee in its
individual capacity (or from the failure of the Owner Trustee in its individual
capacity to perform any covenant) in Section 6.03, or in any of the Operative
Agreements, or (c) those arising or resulting from any of the matters described
in the last sentence of Section 6.01, or (d) those resulting from its failure to
perform the terms of the last sentence of Section 5.04 hereof or from its
failure to use ordinary care in the receipt and disbursement of funds or in
connection with its obligation to invest funds pursuant to Section 15 of the
Lease or Section 4.02 hereof or in compliance with the first Section of Section
6.08, or (e) any liability on the part of Owner Trustee arising out of its
negligence or willful or negligent misconduct in connection with its obligations
under Section 5.01, 6.08 or 9.02 hereof or Section 3.05 of the Indenture, or (f)
those arising under any circumstances or upon any terms where Lessee would not
have been required to indemnify Owner Trustee, in its individual capacity,
pursuant to Section 6.01 or 7.01 of the Participation Agreement; provided, that
                                                                 --------
before asserting its right to indemnification, if any, pursuant to this Section
7.01, Owner Trustee shall first demand its corresponding right to
indemnification pursuant to Section 6.01 or 7.01 of the Participation Agreement
(but need not

                                      13
<PAGE>

exhaust any or all remedies available thereunder). The indemnities contained in
this Section 7.01 extend to the Owner Trustee only in its individual capacity
and shall not be construed as indemnities of the Indenture Estate or the Trust
Estate. The indemnities contained in this Section 7.01 shall survive the
termination of this Trust Agreement and the resignation or removal of the Owner
Trustee. In addition, if necessary, the Owner Trustee shall be entitled to
indemnification from the Trust Estate, subject however to the provisions of
Section 4.01 hereof and the Lien created under the Indenture, for any liability,
obligation, loss, damage, penalty, tax, claim, action, suit, cost, expense or
disbursement indemnified against pursuant to this Section 7.01 to the extent not
reimbursed by Lessee, the Owner Participant or others, but without releasing any
of them from their respective agreements of reimbursement.

          Section 9.01. Resignation of the Owner Trustee; Appointment of
                        ------------------------------------------------
Successor. (a) Resignation or Removal. The Owner Trustee or any successor Owner
---------      ----------------------
Trustee (i) shall resign if required to do so pursuant to Section 5.02(b) of the
Participation Agreement and (ii) may resign at any time without cause by giving
at least 60 days prior written notice to the Owner Participant, the Indenture
Trustee and Lessee, such resignation to be effective upon the acceptance of
appointment by the successor Owner Trustee under Section 9.01(b). In addition,
the Owner Participant may at any time remove the Owner Trustee, or revoke the
trusts created by this Trust Agreement, in either case with or without cause by
a notice in writing delivered to the Owner Trustee, the Indenture Trustee and
Lessee. Any such removal shall be effective upon the acceptance of appointment
by the successor Owner Trustee under Section 9.01(b). In the case of the
resignation or removal of the Owner Trustee, the Owner Participant may appoint a
successor Owner Trustee by an instrument in writing. If a successor Owner
Trustee shall not have been appointed within 30 days after such notice of
resignation or removal, the Owner Trustee or the Indenture Trustee may apply to
any court of competent jurisdiction to appoint a successor Owner Trustee to act
until such time, if any, as a successor shall have been appointed as above
provided. Any successor Owner Trustee so appointed by such court shall
immediately and without further act be superseded by any successor Owner Trustee
appointed as above provided within one year from the date of the appointment by
such court.

          (b) Execution and Delivery of Documents, etc. Any successor Owner
              ----------------------------------------
     Trustee, however appointed, shall execute and deliver to the predecessor
     Owner Trustee, with a copy to Owner Participant, Lessee and Indenture
     Trustee, an instrument accepting such appointment and assuming the
     obligations of Owner Trustee, in its individual capacity and

                                      14
<PAGE>

     as Owner Trustee, under the Operative Agreements to which Owner Trustee is
     a party, and thereupon such successor Owner Trustee, without further act,
     shall become vested with all the estates, properties, rights, powers,
     duties and trusts of the predecessor Owner Trustee in the trust hereunder
     with like effect as if originally named the Owner Trustee herein; but
     nevertheless, upon the written request of such successor Owner Trustee,
     such predecessor Owner Trustee shall execute and deliver an instrument
     transferring to such successor Owner Trustee upon the trusts herein
     expressed, all the estates, properties, rights, powers and trusts of such
     predecessor Owner Trustee, and such predecessor Owner Trustee shall duly
     assign, transfer, deliver and pay over to such successor Owner Trustee all
     monies or other property then held by such predecessor Owner Trustee upon
     the trusts herein expressed. Upon the appointment of any successor Owner
     Trustee hereunder, the predecessor Owner Trustee will complete, execute and
     deliver to the successor Owner Trustee such documents as are necessary to
     cause registration of the Aircraft included in the Trust Estate to be
     transferred upon the records of the FAA or other governmental authority
     having jurisdiction, into the name of the successor Owner Trustee.

          (c) Qualification. Any successor Owner Trustee, however appointed,
              -------------
     shall be a Citizen of the United States, shall be qualified to act as a
     trustee in Delaware (if the trust created hereby is to remain in such
     state) and shall also be a bank or trust company organized under the laws
     of the United States of America or any state thereof 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 Owner Trustee hereunder upon reasonable and customary terms.

          (d) Merger, etc. Any corporation into which the Owner 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 Owner Trustee shall be a party, or any corporation to which
     substantially all the corporate trust business of the Owner Trustee may be
     transferred, shall, subject to the terms of Section 9.01(c), be the Owner
     Trustee hereunder without further act; provided that such corporation shall
     not also be the Indenture Trustee.

          Section 9.02. Co-Trustees and Separate Trustees. If at any time or
                        ---------------------------------
times it shall be necessary or prudent in order to conform to any Applicable Law
of any jurisdiction in which all or any part of the Trust Estate is located, or
the Owner Trustee shall be advised by counsel that it is so necessary or prudent
in the interest of the Owner Participant or the Owner Trustee, or the Owner
Trustee shall have been directed to do so by the Owner Participant, the Owner
Trustee and the Owner Participant shall execute and deliver an agreement
supplemental hereto and all other instruments and agreements necessary or proper
to constitute another bank or trust company or one or more Persons (any and all
of which shall be a Citizen of the United States) approved by the Owner Trustee
and the Owner Participant, either to act as co-trustee or co-trustees, jointly
with the Owner Trustee, or to act as separate trustee or trustees hereunder (any
such co-trustee or separate trustee being herein sometimes referred to as an
"additional trustee"). In the event (i) the Owner Participant shall not have
joined in the execution of such agreements supplemental hereto within ten days
after

                                      15
<PAGE>

the receipt of a written request from the Owner Trustee so to do, or (ii) an
Indenture Event of Default not arising from an Event of Default shall occur and
be continuing, the Owner Trustee may act under the foregoing provisions of this
Section 9.02 without the concurrence of the Owner Participant; and the Owner
Participant hereby appoints the Owner Trustee its agent and attorney-in-fact to
act for it under the foregoing provisions of this Section 9.02 in either of such
contingencies.

          Every additional trustee hereunder shall, to the extent permitted by
Applicable Law, be appointed and act, and the Owner Trustee and its successors
shall act, subject to the following provisions and conditions:

          (a) all powers, duties, obligations and rights conferred upon the
     Owner Trustee in respect of the custody, control and management of monies,
     the Aircraft or documents authorized to be delivered hereunder or under the
     Participation Agreement shall be exercised solely by the corporation
     designated as the Owner Trustee in the first paragraph of this Trust
     Agreement, or its successors as the Owner Trustee hereunder;

          (b) all other rights, powers, duties and obligations conferred or
     imposed upon the Owner Trustee and any limitations thereon shall be
     conferred or imposed upon and exercised or performed by the corporation
     designated as the Owner Trustee in the first paragraph of this Trust
     Agreement or its successors as the Owner Trustee, and such additional
     trustee or trustees jointly, except to the extent that under any Applicable
     Law of any jurisdiction in which any particular act or acts are to be
     performed (including the holding of title to the Trust Estate), the Owner
     Trustee shall be incompetent or unqualified to perform such act or acts, in
     which event such rights, powers, duties and obligations shall be exercised
     and performed by such additional trustee or trustees;

          (c) no power given to, or which it is provided hereby may be exercised
     by, any such additional trustee or trustees shall be exercised hereunder by
     such additional trustee or trustees, except jointly with, or with the
     consent in writing of, the corporation designed as the Owner Trustee in
     this Trust Agreement or its successor as the Owner Trustee, anything herein
     contained to the contrary notwithstanding;

          (d) no trustee hereunder shall be personally liable by reason of any
     act or omission of any other trustee hereunder;

          (e) the Owner Participant, at any time, by an instrument in writing
     may remove any such additional trustee. In the event that the Owner
     Participant shall not have joined in the execution of any such instrument
     within ten days after the receipt of a written request from the Owner
     Trustee so to do, the Owner Trustee shall have the power to remove any such
     additional trustee without the concurrence of the Owner Participant; and
     the Owner Participant hereby appoints the Owner Trustee its agent and
     attorney-in-fact to act for it in such connection in such contingency; and

                                      16
<PAGE>

          (f) no appointing of, or action by, any additional trustee will
     relieve the Owner Trustee of any of its obligations under, or otherwise
     affect any of the terms of the Indenture or affect the interests of the
     Indenture Trustee or the Holders of the Equipment Notes in the Trust
     Estate.

          In case any separate trustee under this Section 9.02 shall die, become
incapable of acting, resign or be removed, the title to the Trust Estate and all
rights and duties of such separate trustee shall, so far as permitted by
Applicable Law, vest in and be exercised by Owner Trustee, without the
appointment of a successor to such separate trustee.

reasonably satisfactory to Owner Trustee to protect the Trust Estate and Owner
Trustee against any and all liabilities, costs and expenses arising out of the
