                           (iii) neither the execution and delivery by the
                  Lessee of the Operative Documents to which it is a party, nor
                  the consummation of any of the transactions by the Lessee

                  Securities Act, as may be required under the Registration
                  Rights Agreement and under the securities laws of any state in
                  which the Pass Through Certificates may be offered for sale if
                  the laws of such state require such action, (ii) the

                  obligation of the Lessee enforceable against the Lessee in
                  accordance with its terms except as the same may be limited by

                  affecting the rights of creditors generally and by general
                  principles of equity and except, in the case of the Lease, as
                  limited by applicable laws which may affect the remedies
                  provided in the Lease, which laws, however, do not make the
                  remedies provided in the Lease inadequate for the practical
                  realization of the rights and benefits provided thereby;

                           (v) there are no pending or threatened actions or
                  proceedings before any court, governmental authority or
                  administrative agency or arbitrator which would materially
                  adversely affect the consolidated financial condition of the
                  Lessee and its consolidated subsidiaries, taken as a whole, or
                  the ability of the Lessee to perform its obligations under the
                  Operative Documents to which it is a party;

                           (vi) the Lessee and its subsidiaries have filed or
                  caused to be filed all Federal, state, local and foreign tax
                  returns which are required to be filed and have paid or caused
                  to be paid all taxes shown to be due and payable on such
                  returns or (except to the extent being contested in good faith
                  and for the payment of which adequate reserves have been
                  provided) on any assessment received by the Lessee or any of
                  its subsidiaries, to the extent that such taxes have become
                  due and payable, except to the extent that the failure to file
                  any such tax returns or to pay any such Taxes could not
                  reasonably be expected to have a material adverse effect on
                  the financial condition of the Lessee and its subsidiaries,
                  taken as a whole; the Federal income tax liability, if any, of
                  the Lessee has been determined by the Internal Revenue Service
                  (or the statute of limitations has expired with respect to a
                  redetermination of such liability) and (except to the extent
                  being contested in good faith and for the payment of which
                  adequate reserves have been provided) paid for all years prior
                  to and including the fiscal year ended December 31, 1992; the
                  Federal income tax returns of the Lessee for the fiscal years
                  ended December 31, 1993 to December 31, 2000, inclusive, are
                  subject to examination by the Internal Revenue Service;

                           (vii) the audited consolidated balance sheet of the
                  Lessee and its subsidiaries as of the end of each of its last
                  three fiscal years, and the related consolidated statements of
                  operations and cash flows for the three fiscal years then
                  ended, fairly present the consolidated financial position of
                  the Lessee and its consolidated subsidiaries as at the end of
                  each such fiscal year and the consolidated results of their
                  operations and cash flows for each such fiscal year in
                  accordance with generally accepted accounting principles
                  applied on a consistent basis (except as may be noted in such
                  financial statements); from December 31, 1997 to the date of
                  this Participation Agreement, there has been no material
                  adverse change in

                  such consolidated financial position of the Lessee and its
                  consolidated subsidiaries, taken as a whole;

                           (viii) except for (A) the filing for recording
                  pursuant to the Transportation Code of the Lease (with the
                  Indenture covering the Aircraft attached), the Trust
                  Agreement, the Indenture and the Instrument of Resignation,
                  (B) the filing of financing statements (and continuation
                  statements at periodic intervals) with respect to the security
                  interests created by such documents under the Uniform
                  Commercial Code of Texas, Utah, Delaware and The District of
                  Columbia, and (C) the taking of possession by the Loan Trustee
                  of the original chattel paper counterpart of the Lease, no
                  further action, including any filing or recording of any
                  document (including any financing statement in respect thereof
                  under Article 9 of the Uniform Commercial Code of any
                  applicable jurisdiction) is necessary or advisable under the
                  laws of the United States of America or any State thereof in
                  order to perfect the Owner Trustee's interest in the Aircraft
                  as against Lessee and any third parties, or to perfect the
                  security interest in the Owner Trustee's interest in the
                  Indenture Estate created under the Indenture in favor of the
                  Loan Trustee (with respect to such portion of the Aircraft as
                  is covered by the recording system established by the Federal
                  Aviation Administration pursuant to the Transportation Code)
                  and in the Lease;

                           (ix) the Lessee is not an investment company or a
                  company controlled by an investment company within the meaning
                  of the Investment Company Act of 1940, as amended;

                           (x) the Lessee is not in default in the performance
                  of any term or condition of the Purchase Agreement which
                  materially adversely impairs the transactions contemplated
                  hereby;

                           (xi) none of the proceeds from the issuance of the
                  Pass Through Certificates or from the acquisition by the Owner
                  Participant of its beneficial interest in the Trust Estate
                  will be used directly or indirectly by the Lessee to purchase
                  or carry any "margin stock" as such term is defined in
                  Regulation G of the Board of Governors of the Federal Reserve
                  System;

                           (xii) the Lessee has not voluntarily subjected the
                  Aircraft to any lease or mortgage, the existence of which has
                  not been disclosed to the Lessor;

                           (xiii) neither the Lessee nor any Person authorized
                  to act on its behalf has (1) directly or indirectly offered
                  any interest in the Trust Estate

                  or any similar interest for sale to, or solicited any offer to
                  acquire the same from, any Person other than the Owner
                  Participant and not more than 35 other institutional
                  investors, or (2) directly or indirectly offered the Pass
                  Through Certificates for sale to any Person other than in a
                  manner required by the Securities Act and by the rules and
                  regulations thereunder;

                           (xiv) no event has occurred and is continuing which
                  constitutes an Event of Default or an Event of Loss would
                  constitute an Event of Default or on Event of Loss but for the
                  requirement that notice be given or time elapse or both; and

                           (xv) the original counterpart of the Lease was

BE DEEMED TO HAVE MADE, AND THE LESSEE HEREBY DISCLAIMS, ANY REPRESENTATION OR
WARRANTY, EXPRESS OR IMPLIED, AS TO THE WORKMANSHIP, DESIGN, PATENT

TO BE IN DEROGATION OF OR CONSTRUED TO LIMIT THE LESSEE'S INDEMNITY OBLIGATIONS
HEREUNDER OR TO EXCUSE THE PERFORMANCE BY THE LESSEE OF ITS OBLIGATIONS UNDER
THIS AGREEMENT OR ANY OTHER OPERATIVE DOCUMENT

                  (4) Claims Excluded. The following are excluded from the
Lessee's agreement to indemnify any Indemnitee under this Section 10(b):

                           (i) Any Claim to the extent caused by acts or events
                  occurring after the earlier of (x) the return of the Aircraft

                  the date of the placement of the Aircraft in storage as
                  provided in Section G of the Return Conditions constitutes the
                  date of return of the Aircraft under the Lease), and (y) the

                  compliance therewith or acts occurring in connection with the
                  exercise of remedies pursuant to Section 15 of the Lease

                  Default thereunder;

                           (ii) Any Claim to the extent attributable to a Tax,
                  or any Claim of the Owner Participant to the extent
                  attributable to a Loss, whether or not Lessee is required to
                  indemnify therefor under Section 10(c) of this Participation
                  Agreement or the Tax Indemnity Agreement, provided that this
                  Section 10(b)(4)(ii) shall not exclude the reasonable
                  out-of-pocket costs, disbursements and expenses incurred with

                  negligence or willful misconduct of such Indemnitee or any of
                  its Related Indemnitee Group (other than any gross negligence
                  or willful misconduct imputed as a matter of law to such
                  Indemnitee solely by reason of its interest in the Aircraft or
                  its status as a party to any of the Operative Documents);

                           (iv) Any Claim to the extent caused by the
                  noncompliance by such Indemnitee or any of its Related
                  Indemnitee Group with any of the terms of, or any

                  Indemnitee Group contained in, this Participation Agreement,
                  any other Operative Document or any Pass Through Trust
                  Document to which such Indemnitee or any of its Related
                  Indemnitee Group is a party or any agreement relating hereto
                  or thereto (except if such non-compliance was based on an
                  inaccurate representation or warranty of the Lessee);

                           (v) Any Claim that constitutes a Permitted Lien

                  (voluntary or involuntary) by or on behalf of such Indemnitee
                  of any Equipment Notes or Pass Through Certificates or any
                  interest in the Trust Estate or the Trust Agreement, or any
                  similar security, other than a transfer by such Indemnitee of
                  its interests in the Aircraft pursuant to Section 9, 10, 15 or
                  20 of the Lease and any related provision of the Indenture
                  including, without limitation, Article 8 thereof except for
                  the cancellation of any Equipment Notes in connection with a
                  refinancing under Section 20 of this Participation Agreement
                  or a redemption under Section 2.08 of the Indenture;

                           (vii) Any Claim to the extent caused by a failure on
                  the part of the Owner Trustee to distribute in accordance with

                  attributable to the Lessee;

                           (viii) Any Claim to the extent such Claim is

                  on the part of any Pass Through Trustee to distribute in

                  attributable to the Lessee;

                  Default that does not also constitute an Event of Default
                  under the Lease or an event which would constitute such an
                  Event of Default but for the requirement that notice be given
                  or time elapse or both;

                           (xi) Any Claim that would not have arisen but for the
                  appointment of a successor or an additional Owner Trustee
                  without the consent of the Lessee unless such successor or an
                  additional Owner Trustee or Indenture Trustee has been
                  appointed in connection with the exercise or remedies pursuant
                  to Section 15 of the Lease following the occurrence and

                  payable or borne by a Person other than the Lessee pursuant to
                  any provision of any Operative Document or any Pass Through

                  ERISA or Section 4975(c)(i) of the Code that arises solely as
                  a result of (x) such Indemnitee's use of plan assets of any
                  "employee benefit plan" as defined in Section 3(3) of ERISA or
                  a "plan" as defined in Section 4975 of the Code, including any

                  event of doubt, any Claim shall be allocated between the
                  Aircraft and such other aircraft in the same proportion that
                  the then outstanding Equipment Notes bear to the then
                  outstanding notes issued with respect to the other aircraft
                  and held by the Pass Through Trustees; and

                           (xxii) Any Claim attributable to the deregistration
                  of the Aircraft as a result of the failure of the Owner
                  Participant to be a Citizen of the United States.

A limitation on the Claims of one Indemnitee under this Section 10(b)(4) shall
not provide a basis for limiting any Claim of any other Indemnitee.

                  (5) Insured Claims. In the case of any Claim indemnified by
the Lessee hereunder which is covered by a policy of insurance maintained by the
Lessee pursuant to Section 11 of the Lease, each Indemnitee agrees to cooperate,
at the Lessee's expense, 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.

                  (6) Claims Procedure. An Indemnitee shall promptly notify the
Lessee of any Claim as to which indemnification is sought, provided that the
failure to provide such prompt notice shall not release the Lessee from any of
its obligations to indemnify hereunder. Any amount payable to any Indemnitee
pursuant to this Section 10(b) shall be paid on an After-Tax Basis within thirty
days after receipt of a written demand therefor from such Indemnitee accompanied
by a written statement describing in reasonable detail the Claims which are the
subject of and basis for such indemnity and the computation of the amount so
payable. Subject to the rights of insurers under policies of insurance
maintained pursuant to Section 11 of the Lease, so long as no Event of Default
shall have occurred and be continuing, the Lessee (at its sole cost and expense)
shall have the right to investigate, and the right in its sole discretion to
defend or compromise, any Claim for which indemnification is sought under this
Section 10(b); provided that in no event shall the right of any Indemnitee under
this Section 10(b) be adversely affected thereby and provided further that no
such Claim shall involve a material risk of the sale, forfeiture or loss
(including loss of use) of the Airframe or any Engine or any interest therein or
any meaningful risk of criminal liability or any material risk of civil penalty
against Lessor, any Pass Through Trustee or Owner Participant, and the
Indemnitee shall cooperate with all reasonable requests of the Lessee in
connection therewith; provided, however, that so long as an Event of Default has
occurred and is continuing, such Indemnitee shall have the right, along with the
concomitant right of the Lessee, to investigate, defend or compromise any such
Claim; provided that the Lessee shall reimburse such Indemnitee for all
reasonable costs and expenses incurred by it in connection therewith. The Lessee
will provide the Indemnitee with such information not within the control of such
Indemnitee, as is in the Lessee's control or as reasonably available to the
Lessee, which such Indemnitee may reasonably request and shall otherwise
cooperate with such Indemnitee so as to enable such Indemnitee to fulfill its
obligations under this Section 10(b)(6). Where the Lessee or the insurers under
a policy of insurance maintained by the Lessee undertake the defense of an
Indemnitee with respect to a Claim, and so long as the Lessee is entitled to
control such defense, no additional legal fees or expenses of such Indemnitee in
connection with the defense of such Claim shall be indemnified hereunder unless
such fees or expenses were incurred at the request of the Lessee or such
insurers; provided, however, that if (i) in the written opinion of counsel to
such Indemnitee an actual or potential material conflict of interest exists
where it is advisable for such Indemnitee to be represented by separate counsel
or (ii) such Indemnitee has been indicted or otherwise charged in a criminal
complaint and such Indemnitee informs the Lessee that such Indemnitee desires to
be represented by separate counsel, the reasonable

                                       24
                          AA-Boeing EETC-Leased Aircraft Participation Agreement
<PAGE>

fees and expenses of any such separate counsel shall be borne by the Lessee.
Subject to the requirements of any policy of insurance, an Indemnitee may
participate at its own expense in any judicial proceeding controlled by the
Lessee pursuant to the preceding provisions; provided 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,
significantly interfere with such control; and such participation shall not
constitute a waiver of the indemnification provided in this Section 10(b).
Notwithstanding anything to the contrary contained herein, (x) the Lessee shall
not under any circumstances be liable for the fees and expenses of more than one
counsel for each of (i) the Owner Participant and the Owner Trustee (and their
respective successors and permitted assigns, agents and servants and other
members of their respective Related Indemnitee Groups) and (ii) the
Subordination Agent, any Pass Through Trustee and the Loan Trustee (and their
respective successors and permitted assigns, agents and servants) except in the
case specified in the proviso to the fourth sentence of this paragraph (6) and
(y) the Lessee shall not defend or compromise any Claim if such proceedings will
involve a material risk of the sale, forfeiture or loss of, or the creation of
any Lien (other than a Permitted Lien) on the Airframe, any Engine or any part
of any thereof, or the Indenture Estate or the Trust Estate or any part of any
thereof, unless the Lessee shall have provided security for Lessee's obligations
under this Section 10(b) with respect to such Claim reasonably satisfactory to
the relevant Indemnitees in respect to such risk.

                  (7) Subrogation. To the extent that a Claim indemnified by the
Lessee under this Section 10(b) is in fact paid in full by the Lessee and/or an
insurer under a policy of insurance maintained by the Lessee pursuant to Section
11 of the Lease, the Lessee and/or such insurer, as the case may be, shall be
subrogated to the rights and remedies of the Indemnitee on whose behalf such
Claim was paid (other than rights of such Indemnitee under insurance policies
maintained at its own expense) with respect to the transaction or event giving
rise to such Claim, except that the Lessee shall not be subrogated to any rights
or remedies that the Owner Trustee may have against the Owner Participant under
Section 7.1 of the Trust Agreement or that the Loan Trustee may have against the
Owner Trustee under Section 11.01 of the Indenture. So long as no Event of
Default (or event that with the lapse of time would constitute an Event of
Default under Section 14(a), 14(g), 14(h) or 14(i) of the Lease) shall have
occurred and be continuing, should an Indemnitee receive any refund, in whole or
in part, with respect to any Claim paid by the Lessee hereunder, it shall
promptly pay the amount refunded (but not an amount in excess of the amount the
Lessee or any of its insurers has paid in respect of such Claim) over to the
Lessee. Moreover, if, by reason of any Claim that the Lessee has paid or
indemnified against pursuant to this Section 10(b), an Indemnitee realizes an
actual reduction in any Taxes that was not previously taken into account in
computing a payment by the Lessee pursuant to this Section 10(b), then such
Indemnitee shall promptly pay to the Lessee an amount equal to the actual net
reduction in Taxes realized by such Indemnitee attributable thereto plus the
actual reduction in Taxes realized by such Indemnitee as a result of any payment
to the Lessee pursuant to this sentence. Each

                                       25
                          AA-Boeing EETC-Leased Aircraft Participation Agreement
<PAGE>

Indemnitee shall in good faith use reasonable diligence in filing its tax
returns and in dealing with taxing authorities to seek and claim any tax
benefits that would result in such net reductions in Taxes.

                  (8) No Guaranty. Nothing set forth in this Section 10(b) shall
constitute a guarantee by the Lessee that the Aircraft shall have any particular
useful life or residual value or a guarantee to the Loan Trustee, the
Subordination Agent or any Pass Through Trustee that the Equipment Notes will be
paid.

         (c) General Tax Indemnity.

                  (1) General. Subject to Section 10(c)(2) hereof, the Lessee
agrees to indemnify, protect, defend and hold harmless on an After-Tax Basis
each Tax Indemnitee against any and all Taxes imposed with respect to any period
after the Closing Date on any Tax Indemnitee, the Lessee, the Aircraft, the
Airframe, any Engine or any Part, upon or with respect to (A) the Aircraft, the
Airframe, any Engine or any Part or any interest in any thereof or the
applicability of the Lease to the Aircraft, the Airframe, any Engine or any Part
or any interest in any thereof, (B) the lease, sublease, hiring, acceptance,
delivery, transport, location, ownership, control, insurance, possession, use,
non-use, substitution, airworthiness, state of airworthiness, control,
maintenance, repair, replacement, operation, registration, re-registration,
condition, sale, storage, modification, alteration, return, transfer or other
disposition of the Aircraft, the Airframe, any Engine or any Part, (C) any Basic
Rent or Supplemental Rent payable by the Lessee, (D) the exercise of remedies
pursuant to Section 15 of the Lease in connection with an Event of Default that
shall have occurred and be continuing or (E) otherwise in connection with the
transactions contemplated by the Operative Documents.

                  (2) Taxes Excluded from Indemnity. The Lessee shall have no
obligation under the Lease with respect to Taxes described in any one or more of
the following clauses; provided that clauses (ii) and (vi) below shall not apply
in determining the additional amount necessary to make any payment under this
Section 10 on an After-Tax Basis:

                           (i) [Intentionally left blank];

                           (ii) Taxes imposed by any government or taxing
                  authority on, based on, measured by or with respect to
                  capital, net worth, doing business, retained earnings, tax
                  preferences, gross or net income or gross or net receipts or
                  that are franchise Taxes; provided that there shall not be
                  excluded by this clause (ii)(x) any such Taxes imposed by any
                  government or taxing authority located outside the United
                  States to the extent such Taxes would have been imposed had
                  the sole connection between the Tax Indemnitee and such
                  government or taxing authority been (I) the

                                       26

<PAGE>

                  registration, location, use, operation or presence of the
                  Aircraft, the Airframe, any Engine or any Part in such
                  jurisdiction, (II) the presence, activity or other connection
                  of the Lessee or an Affiliate of the Lessee in or with such
                  jurisdiction, or (III) the Lessee's making a payment from or
                  through such jurisdiction or (y) any sales, use, transfer,
                  license, value added, property, excise or rental Taxes (or
                  Taxes in the nature thereof) imposed by any government or
                  taxing authority;

                           (iii) Taxes imposed on any Tax Indemnitee to the
                  extent such Taxes result from, or would not have been imposed
                  but for, (w) a Lessor's Lien, a Subordination Agent's Lien or
                  a Trustee's Lien, (x) the willful misconduct or gross
                  negligence of such Tax Indemnitee, (y) the breach or
                  inaccuracy of any representation, warranty or covenant of such
                  Tax Indemnitee in the Operative Documents or the Pass Through
                  Trust Documents (which is not attributable to a breach of any
                  representation, warranty or covenant of the Lessee), or (z)
                  the failure of such Tax Indemnitee to comply with any
                  certification, information, documentation, reporting or other
                  similar requirement, if such compliance is necessary or
                  appropriate to claim any relief from such Taxes for which such
                  Tax Indemnitee was eligible, unless such failure to comply is
                  due to the failure of the Lessee to provide timely written
                  notice to such Tax Indemnitee of such requirement or otherwise
                  to comply with its obligations under Section 10(c)(6) hereof;

                           (iv) Taxes imposed on any Tax Indemnitee in excess of
                  the Taxes that would have been imposed and indemnified against
                  had there not been a transfer (whether voluntary or
                  involuntary) (x) by a Tax Indemnitee of any interest in the
                  Aircraft, the Airframe, any Engine, any Part, the Trust
                  Estate, or any interest arising under any Operative Document
                  (other than such a transfer pursuant to Section 9, 10, or 20
                  of the Lease or the exercise of remedies pursuant to Section
                  15 of the Lease) or (y) of any interest (direct or indirect)
                  in a Tax Indemnitee; provided that in the case of any such
                  transfer by the initial Owner Participant within two years of
                  the Commencement Time, this clause (iv) shall apply to the
                  transferee of the initial Owner Participant only (I) if such
                  transfer is to a transferee Owner Participant that is not a
                  United States person for U.S. federal income tax purposes or
                  has its principal office, or participates in this transaction
                  through an office, located outside the United States or (II)
                  with respect to Taxes imposed on such transferee in the
                  relevant jurisdiction of a type that would not have been
                  incurred by a typical bank, leasing company, financial
                  institution or other company (which may include insurance
                  companies and utilities) regularly engaged in leasing
                  transactions;

                  a transfer pursuant to Section 9, 10, or 20 of the Lease or
                  the exercise of remedies pursuant to Section 15 of the Lease)
                  or (y) of any interest (direct or indirect) in a Tax
                  Indemnitee;

                           (vi) Taxes to the extent imposed with respect to any
                  period commencing after (x) the return of the Aircraft to the
                  Lessor pursuant to the Return Conditions or, if the Aircraft
                  is stored pursuant to Section G of the Return Conditions of
                  this Participation Agreement following termination thereof,
                  the date of the placement of the Aircraft in storage or (y)
                  the expiration or earlier termination of the Lease under
                  circumstances not requiring the return of the Aircraft;
                  provided that there shall not be excluded by this clause (vi)
                  any Taxes to the extent (I) attributable to events occurring
                  or matters arising prior to or simultaneously with the earlier
                  of such times, any failure of the Lessee to perform its
                  obligations under the Lease in full compliance therewith, or
                  the exercise of remedies pursuant to Section 15 of the Lease
                  in connection with an Event of Default that shall have
                  occurred and be continuing or (II) imposed with respect to any
                  payment by the Lessee under the Operative Documents after such
                  date;

                           (vii) Taxes imposed on any Tax Indemnitee by any
                  government or taxing authority to the extent such Taxes would
                  not have been imposed but for a present or former connection
                  between such Tax Indemnitee and such government or taxing
                  authority unrelated to the transactions contemplated by the
                  Operative Documents or the Pass Through Trust Documents;

                           (viii) Taxes to the extent such Taxes would not have
                  been imposed but for an amendment to any Operative Document or
                  any Pass Through Trust Document without the prior written
                  consent of the Lessee, unless such amendment is requested by
                  the Lessee, is expressly required by any Operative Document or
                  any Pass Through Trust Document or is made as a result of an
                  Event of Default that shall have occurred and be continuing;

                           (ix) Taxes for so long as such Taxes are being
                  contested in accordance with the provisions of Section
                  10(c)(5) hereof, except to the extent a payment by the Lessee
                  is required pursuant to such Section 10(c)(5);

<PAGE>

                           (x) Taxes imposed on any Tax Indemnitee in excess of
                  the Taxes that would have been imposed if such Tax Indemnitee
                  at all times had been a United States person for U.S. federal
                  income tax purposes;

                           (xi) value added Taxes imposed in lieu of income Tax
                  by the United States or any state or local government or
                  taxing authority thereof or therein;

                           (xii) Taxes that are directly attributable to a
                  "prohibited transaction" within the meaning of Section 406 of
                  ERISA or Section 4975(c)(i) of the Code that arise solely as a
                  result of (x) such Indemnitee's use of plan assets of any
                  "employee benefit plan" as defined in Section 3(3) of ERISA or
                  a "plan" as defined in Section 4975 of the Code, including any
                  entity whose assets are deemed to constitute plan assets under
                  Department of Labor Reg.ss.2510.3-101, to acquire or hold its
                  interest(s) in the Trust Estate or in any Equipment Note, as
                  applicable or (y) in the case of a Tax Indemnitee which is the
                  Owner Participant or any of its Affiliates, the reliance by
                  any plan maintained or sponsored by the Owner Participant or
                  any of its Affiliates on the administrative exemption issued
                  to any of the Placement Agents;

                           (xiii) Taxes to the extent imposed by reason of the
                  trust created under the Trust Agreement not being treated as a
                  "grantor trust" or otherwise being disregarded for U.S.
                  federal income tax purposes, except to the extent such Taxes
                  would have otherwise been imposed on another Tax Indemnitee
                  and been subject to indemnification by the Lessee under this
                  Section 10(c);

                           (xiv) Taxes on, based on, measured by or with respect
                  to any consideration payable for services rendered by any Pass
                  Through Trustee, the Subordination Agent, the Owner Trustee or
                  the Loan Trustee; and

                           (xv) [Intentionally left blank];

                  (3) Tax Savings. If, by reason of any Claims or Taxes paid or
indemnified against by the Lessee pursuant to Section 10(b) or this Section
10(c), any Indemnitee or Tax Indemnitee (or any related Person) at any time
realizes a net reduction in any Taxes not indemnified against by the Lessee and
not taken into account previously in computing the amount of any indemnity
payable by the Lessee under Section 10(b) or this Section 10(c), such Indemnitee
or Tax Indemnitee shall, subject to Section 10(c)(9) hereof if an Event of
Default or Specified Default has occurred and is continuing, promptly pay to the
Lessee an amount that, after subtraction of any further reduction in Taxes such
Tax Indemnitee or Indemnitee realizes as a result of the payment thereof,

                                       29
                          AA-Boeing EETC-Leased Aircraft Participation Agreement
<PAGE>

which reduction was not previously taken into account in computing an amount
payable by the Lessee hereunder, is equal to the amount of such net Tax
reduction; provided that any subsequent loss of a Tax benefit for which a
payment has been made to the Lessee under this Section 10(c)(3) (or which was
taken into account in computing an amount payable by the Lessee under this
Section 10(c)) shall be treated as an indemnifiable Tax hereunder without regard
to the exclusions set forth in Section 10(c)(2) hereof. Each Tax Indemnitee
shall in good faith use diligence in filing its tax returns and in dealing with
taxing authorities to seek and claim any Tax benefit that would result in such a
reduction in Taxes or would minimize the Taxes indemnifiable by the Lessee
hereunder.

                  (4) Payment. The Lessee shall pay any Tax for which it is
liable pursuant to this Section 10(c) directly to the appropriate taxing
authority, if allowable, or if not so allowable, directly to the relevant Tax
Indemnitee. Any amount payable directly to any Tax Indemnitee pursuant to this
Section 10(c) shall be paid to such Tax Indemnitee on or prior to the later of
(A) 30 days after receipt by the Lessee of a written demand therefor from such
Tax Indemnitee accompanied by a written statement describing in reasonable
detail the Taxes that are the subject of such indemnity and the computation of
the amount so payable, (B) three Business Days prior to the due date for the
payment of such Taxes (including all extensions) or (C) in the case of amounts
which are being contested in accordance with Section 10(c)(5) hereof, the time
such contest (including all appeals, if any) is finally resolved; provided that
the Lessee shall pay any amounts due pursuant to Section 10(c)(5) hereof at the
time or times required by such clause. If requested by a Tax Indemnitee in
writing, the Lessee shall furnish to such Tax Indemnitee the original or a
certified copy of a receipt (if any is reasonably available to the Lessee) for
the Lessee's payment of any Tax directly to a taxing authority pursuant to this
Section 10(c) or such other evidence of such payment by the Lessee as is
reasonably acceptable to such Tax Indemnitee and reasonably available to the
Lessee.

                  (5) Contests; Refunds. If a written claim is made against any
Tax Indemnitee for any Tax for which the Lessee may be obligated pursuant to
this Section 10(c), or if any Tax Indemnitee shall determine that any Tax for
which the Lessee may be obligated pursuant to this Section 10(c) may be payable,
such Tax Indemnitee shall notify the Lessee promptly in writing. If timely
requested by the Lessee in writing, such Tax Indemnitee shall in good faith
diligently contest through appropriate administrative and judicial proceedings
(including pursuing all judicial appeals, but not to the United States Supreme
Court) in the name of such Tax Indemnitee (or, if requested by the Lessee and
permitted by applicable law, and subject to the conditions set forth in the next
sentence, permit the Lessee to contest in the name of the Lessee or such Tax
Indemnitee), the validity, applicability and amount of such Tax by (x) resisting
payment thereof, (y) not paying the same except under protest, if protest be
necessary or proper, or (z) if payment be made, seeking a refund thereof in
appropriate administrative and judicial proceedings; provided that (A) prior to
taking such administrative or judicial action the Lessee shall have agreed to
pay (and shall pay) such Tax Indemnitee on

                                       30
                          AA-Boeing EETC-Leased Aircraft Participation Agreement
<PAGE>

demand all reasonable out-of-pocket costs and expenses which such Tax Indemnitee
may incur in connection with contesting such claim, including, without
limitation, all reasonable legal, accountants' and investigatory fees and
disbursements, (B) if such contest shall be conducted in a manner requiring the
payment of the Tax, the Lessee shall advance to such Tax Indemnitee (on an
interest-free basis) the amount of such payment and shall agree to indemnify
such Tax Indemnitee against any adverse tax consequences to such Tax Indemnitee
resulting from such interest-free loan, (C) the action to be taken will not
result in any material danger of forfeiture, sale or loss of the Aircraft, the
Airframe or any Engine (unless the Lessee shall have provided to the Lessor a
bond or other sufficient protection against such risk acceptable to the Lessor
and such Tax Indemnitee), (D) if an Event of Default or Specified Default shall
have occurred and be continuing, the Lessee shall have provided security for its
related tax indemnity obligation reasonably acceptable to such Tax Indemnitee,
(E) prior to commencing any contest involving income Taxes or any judicial
action (but not administrative action) involving non-income Taxes, if reasonably
requested by the Tax Indemnitee, the Lessee shall have provided to such Tax
Indemnitee an opinion of tax counsel (who may be an employee of American in the
case of a judicial action involving non-income Taxes) selected by the Lessee and
reasonably acceptable to such Tax Indemnitee to the effect that there is a
reasonable basis (consistent with ABA Opinion 85-352) for contesting such claim,
and (F) the amount of the potential indemnity (together with the amount of all
similar or logically related claims that have been or could be raised in any
audit involving such Tax Indemnitee for which the Lessee may be liable to pay an
indemnity under this Section 10(c)) exceeds $10,000 in connection with the
Lease. The Lessee shall be permitted to conduct such a contest (i) in its name
if contesting in its name is allowable under applicable law or (ii) in the name
of the relevant Tax Indemnitee, if consented to by the relevant Tax Indemnitee
(it being understood that the relevant Tax Indemnitee shall consider in good
faith the Lessee's request to conduct a contest in the name of the relevant Tax
Indemnitee). Otherwise, the relevant Tax Indemnitee shall conduct such contest.
In any contest under this Section 10(c)(5) conducted by the Lessee, the Lessee
shall determine the forum and manner in which such contest shall be conducted
and, upon the written request of the relevant Tax Indemnitee, will advise such
Tax Indemnitee of that status of such contest. In any contest under this Section
10(c)(5) conducted by a Tax Indemnitee, such Tax Indemnitee shall determine the
forum for such contest and the manner in which it shall be conducted; provided
that such Tax Indemnitee shall consult in good faith with the Lessee and its
counsel, and provide to the Lessee and its counsel any communications to or from
the relevant taxing authority or administrative or judicial body, with respect
to the issues for which the Lessee may be obligated under this Section 10(c).

         If any Tax Indemnitee shall obtain a refund of all or part of any Tax
paid by the Lessee or for which the Lessee shall have reimbursed such Tax
Indemnitee, such Tax Indemnitee shall pay the Lessee an amount equal to the
amount of such refund, including any interest received on such refund
attributable to such Tax that is properly attributable

                                       31
                          AA-Boeing EETC-Leased Aircraft Participation Agreement
<PAGE>

to the period subsequent to such payment or reimbursement by the Lessee, reduced
by any Taxes payable by such Tax Indemnitee as a result of the receipt or
accrual of such refund and interest, and increased by any reduction in Taxes
actually realized by such Tax Indemnitee as a result of any payment by such Tax
Indemnitee pursuant to this sentence, which reduction was not previously taken
into account in computing an amount payable by the Lessee hereunder. If it is
later determined that the Tax Indemnitee was not entitled to such refund, the
portion of such refund that is repaid, recaptured or disallowed will be treated
as Taxes for which the Lessee must indemnify the Tax Indemnitee pursuant to this
Section 10(c) but without regard to Section 10(c)(2) hereof.

         If a Tax Indemnitee elects not to contest any Tax that it is otherwise
required to contest in accordance with this Section 10(c)(5), or elects to
settle, compromise or otherwise terminate any such contest without the consent
of the Lessee, such election shall constitute a waiver by such Tax Indemnitee of
any right to any amount that might otherwise be payable by the Lessee pursuant
to this Section 10(c) with respect to such Tax (other than any expenses of the
contest) and, if the Lessee has theretofore provided such Tax Indemnitee with an
interest-free loan to pay such amount, such Tax Indemnitee shall promptly repay
an amount which, after subtraction of any further reduction in Taxes actually
realized by such Tax Indemnitee as a result of such payment, which reduction was
not previously taken into account in computing an amount payable by the Lessee
hereunder, shall be equal to the amount of such interest-free loan, together
with interest on the amount of such loan from the date such loan was made to the
date of repayment pursuant to this sentence at the rate that would have been
paid by the relevant taxing authority had such contest resulted in a refund.

                  (6) Reports; Returns; Forms. If any report or return is
required to be filed with respect to any property Tax (or any Tax in the nature
of a property Tax) subject to indemnification by the Lessee under this Section
10(c), the Lessee shall, if permitted by applicable law to do so, timely file
such report or return (except for any such report or return as to which the
Lessor has notified the Lessee that the Lessor intends to file such report or
return) so as to show ownership of the Aircraft in the Lessor and, if requested
by the Lessor, send a copy of such report or return to the Lessor; provided that
the Lessor shall have furnished the Lessee, at the Lessee's request, with such
information, not within the control of the Lessee, as is in the control of the
Lessor or the Owner Participant, if any, and is reasonably available to such
Person and necessary to file such report or return (it being understood that
neither the Lessor nor the Owner Participant shall be required to furnish copies
of its actual Tax returns). If the Lessee is not permitted by applicable law to
file any such report or return with respect to such Tax, or has insufficient
information to do so, the Lessee will promptly notify the Lessor of such
requirement and prepare and deliver to the Lessor a proposed form of such report
or return, within a reasonable time prior to the time such report or return is
to be filed. If any report or return is required to be filed with respect to any
Tax (other than a property Tax or Tax in the nature thereof) for which the
Lessee is obligated under this Section 10(c), the Lessee will notify the

                                       32
                          AA-Boeing EETC-Leased Aircraft Participation Agreement
<PAGE>

relevant Tax Indemnitee thereof upon the Lessee's obtaining actual knowledge of
such requirement. In addition, the Lessee will furnish upon written request such
data in its possession or otherwise reasonably available to it as any Tax
Indemnitee may reasonably request to enable such Tax Indemnitee to comply with
the requirements of any taxing authority arising out of such Tax Indemnitee's
participation in the transactions contemplated by the Lease.

         Each Tax Indemnitee agrees to furnish from time to time to or as
directed by the Lessee, upon the Lessee's written request and at the Lessee's
expense, such duly executed and properly completed forms, statements or
certificates as may be necessary or appropriate in order to claim any available
reduction of any Tax for which the Lessee may be obligated under this Section
10(c); provided that the Lessee shall have furnished such Tax Indemnitee with
any information necessary to complete such form, statement or certificate that
is not otherwise reasonably available to such Tax Indemnitee.

                  (7) Verification. At the request of the Lessee, any statement
prepared by a Tax Indemnitee pursuant to this Section 10(c), and any amount
payable by or to the Lessee pursuant to this Section 10(c), shall be verified
and certified by a nationally recognized firm of independent accountants (which
may be the firm that audits such Tax Indemnitee's financial statements) selected
by the Tax Indemnitee and reasonably acceptable to the Lessee. The costs of any
such verification and certification shall be borne by the Lessee unless such
firm determines that any amount payable (A) by the Lessee to a Tax Indemnitee is
less than 95% of the amount determined to be so payable by such Tax Indemnitee
or (B) by any Tax Indemnitee to the Lessee is greater than the amount determined
to be so payable by such Tax Indemnitee by at least 5%, in either of which cases
the cost of such verification and certification shall be paid by the Tax
Indemnitee. In the event such firm shall determine that such amount or statement
is incorrect, then such firm shall determine what it believes to be the correct
amount, and such determination shall be binding upon the parties. Any Tax return
of a Tax Indemnitee provided to such firm shall be confidential and shall be
used by it only for purposes of such verification and certification and shall
not be disclosed to the Lessee.

                  (8) Meaning of Certain Terms. For purposes of this Section
10(c), any reference to the Lessor, the Owner Trustee, the Owner Participant,
the Loan Trustee, Indenture Estate or a Tax Indemnitee shall, with respect to
any Tax imposed with respect to a combined, consolidated or affiliated group of
which such Person is a member, also include such group and any member thereof.

                  (9) Application of Payments During Event of Default. If, at
the time any amount would otherwise be payable to the Lessee under this Section
10(c), an Event of Default or Specified Default shall have occurred and be
continuing, such amount shall be held by the relevant Tax Indemnitee as security
for the obligations of the Lessee under the Operative Documents and invested in
accordance with Section 25 of the Lease and, if

                                       33
                          AA-Boeing EETC-Leased Aircraft Participation Agreement
<PAGE>

the Lessor declares the Lease to be in default pursuant to Section 14 thereof,
applied against the Lessee's obligations under the Operative Documents as and
when due. At such time as there shall not be continuing any such Event of
Default or Specified Default, such amount shall be paid to the Lessee to the
extent not previously applied under the preceding sentence.

                  (10) Non-Parties. If a Tax Indemnitee is not a party to this
Agreement, the Lessee may require such Tax Indemnitee to agree in writing, in a
form reasonably acceptable to the Lessee, to the terms of this Section 10(c)
prior to making any payments to such Tax Indemnitee under this Section 10(c).

         (d) Survival. The Indemnities, representations and warranties and other
obligations of the Lessee (subject to Section 10(b)(4)(i) and 10(c)(2)(vi)) and
the obligations of each Indemnitee and Tax Indemnitee under this Section 10,
shall survive the expiration or other termination of the Operative Documents or
any of the Pass Through Trust Documents.

         SECTION 11. Representations and Warranties.

         (a) The Owner Participant represents and warrants that neither it nor
any person authorized by it to act on its behalf has directly or indirectly

or permitted by the Securities Act of 1933, as amended, and by the rules and
regulations thereunder. The Owner Participant represents and warrants that its
interest in and to the Trust Estate and the Trust Agreement was acquired for its
own account and it was purchased for investment and not with a view to any
resale or distribution thereof; provided, however, that such representation
shall in no way limit the Owner Participant's right to transfer such interest
pursuant to, and in accordance with all the terms and conditions of, Section
19(c) hereof.

         (b) Each of the Owner Participant and the Owner Trustee represents that
neither it nor any Person authorized to act on its behalf has (i) directly or
indirectly offered any interest in or to the Trust Estate or the Trust Agreement

the Owner Participant and not more than 35 other institutional investors, (ii)
directly or indirectly offered the Equipment Notes or Pass Through Certificates
for sale to, or solicited any offer to acquire any of the same from, anyone

institutional investors or (iii) offered any interest in the Trust Estate or any
Equipment Notes or Pass Through Certificates in a manner that would violate the
Securities Act of 1933, as amended, the regulations thereunder or judicial or
administrative interpretations thereof having the force of law.

         (c) The Owner Trustee represents and warrants, both in its individual
capacity and as trustee, that it has not directly or indirectly offered any

any offer to acquire any of the same from, anyone.

                  respectively, to authenticate the Equipment Notes and the Pass

                           (viii) [Intentionally left blank];

                           (ix) There are no Taxes payable by State Street, the
                  Loan Trustee, the Subordination Agent or any Pass Through
                  Trustee imposed by the State of Connecticut or any political
                  subdivision or taxing authority thereof in connection with the
                  execution, delivery or performance by State Street, the Loan
                  Trustee, the Subordination Agent or any Pass Through Trustee
                  of any Operative Document or any Pass Through Trust Document
                  (other than franchise or other taxes based on or measured by
                  any fees or compensation received by any such Person for

                  contemplated by the Operative Documents or the Pass Through
                  Trust Documents), and there are no Taxes payable by any Pass
                  Through Trustee imposed by the State of Connecticut or any

                  received by such Pass Through Trustee for services rendered in
                  connection with the transactions contemplated by the Operative
                  Documents or the Pass Through Trust Documents) and, assuming
                  that the Pass Through Trusts will not be taxable for Federal
                  income tax purposes as corporations, but, rather, will be
                  characterized for such purposes as grantor trusts or
                  partnerships, the Pass Through Trusts will not be subject to
                  any Taxes imposed by the State of Connecticut or any political
                  subdivision thereof.

                           (x) Except with the consent of the Lessee, which

                  Pass Through Trustee solely through its offices within the
                  State of Connecticut, except for such services that may be
                  performed for it by various agents, but not directly by it, in
                  other states.

                           (xi) There are no pending or, to its knowledge,

                  Original Notes in the aggregate principal amount of the amount
                  specified in Schedule I, free and clear of Liens attributable
                  to it; and

                           (ii) this Agreement has been duly authorized,
                  executed and delivered by the Original Loan Participant and
                  constitutes the legal, valid and binding obligation of the
                  Original Loan Participant, enforceable against the Original
                  Loan Participant in accordance with its terms, except as such
                  enforceability may be limited by application of bankruptcy,
                  insolvency, moratorium or similar laws affecting the rights of
                  creditors generally, and by general principles of equity.

         SECTION 12. Certain Covenants.

         (a) The Lessee agrees promptly to pay all expenses, fees and other

                           (ii) all other reasonable expenses incurred in
                  connection with such actions and transactions, including,

<PAGE>

                  document production or reproduction expenses, the fees,
                  expenses and/or commissions payable to each of the Placement
                  Agents in connection with the offering and sale of the Pass
                  Through Certificates, printing and document production or

                  filing of the instruments and financing statements described
                  in this Agreement.

         Notwithstanding the foregoing, the Lessee shall not pay the fees,
expenses and disbursements of Fulbright & Jaworski L.L.P, special counsel for
the Owner Participant, the Owner Participant Guarantor, the Original Loan
Participant and the Liquidity Provider.

         Each of the Owner Trustee, the Owner Participant, the Original Loan
Participant, the Lessee, each Pass Through Trustee, the Liquidity Provider, the
Placement Agents, the Subordination Agent, the Indenture Trustee and the Loan
Trustee shall promptly submit to the Lessee copies of the invoices in respect of

         The Owner Participant shall pay any break costs, exit fees and other
amounts owing to, and costs and liabilities incurred by, the holders of the
Original Note in connection with any repayment of the Original Note in
connection with the refinancing contemplated hereunder.

         (b) The Owner Participant covenants that if (i) it ceases to be a
Citizen of the United States and (ii) either (A) the Aircraft shall or would
thereupon become ineligible for registration in the name of the Owner Trustee
under the Transportation Code as in effect at such time, or under the law of the
current jurisdiction of registry of the Aircraft, as the case may be, and the
regulations then applicable thereunder, or (B) the Aircraft is registered in a
jurisdiction other than the United States in circumstances in which clause (A)
does not apply and the Lessee at any time upon notice to the Owner Participant
proposes to register the Aircraft within four months in any jurisdiction to
which clause (A) would apply upon such reregistration, then the Owner
Participant at its own expense shall promptly (and, in any event, within a
period of 30 days) either transfer, pursuant to Section 19(c) hereof, such of
its right, title and interest in and to the Trust Agreement, the Trust Estate,
and this Agreement, or take such other action, as may be necessary to prevent
any deregistration of the Aircraft or to make possible its registration in the
United States. Each party hereto agrees to take such steps, at the Owner
Participant's expense, as the Owner Participant shall reasonably request in
order to assist the Owner Participant in complying with its obligations under
this Section 12(b). The Owner Participant hereby agrees to indemnify the Lessee,
the Indenture Trustee, the Liquidity Provider, the Owner Trustee, the Loan
Trustee, the Subordination Agent and each Pass Through Trustee and against any
and all losses, liabilities and expenses incurred by the Lessee, the Indenture

                                       43
                          AA-Boeing EETC-Leased Aircraft Participation Agreement
<PAGE>

Trustee, the Loan Trustee, the Subordination Agent and each Pass Through Trustee
to the extent that any such losses, liabilities or expenses are caused by the
Owner Participant's breach of the first sentence in this Section 12(b).

         (c) The Owner Trustee in its individual capacity covenants that if at
any time it shall cease to be a Citizen of the United States, it will resign
immediately as Owner Trustee (if and so long as such citizenship is necessary
under the Transportation Code, or the law of the current jurisdiction of the
registry of the Aircraft, as the case may be, as in effect at such time or, if
it is not necessary, if and so long as the Owner Trustee's citizenship (in its
individual capacity) would have any adverse effect on the Lessee or any
Participant). The Owner Trustee in its individual capacity hereby
unconditionally agrees with and for the benefit of the parties to this Agreement
that the Owner Trustee in its individual capacity will not directly or
indirectly create, incur, assume or suffer to exist any Lessor's Liens on or
against any part of the Trust Estate, the Indenture Estate or the Aircraft
arising out of any act or omission of or claim against or affecting the Owner
Trustee in its individual capacity, and the Owner Trustee in its individual
capacity agrees that it will at its own cost and expense promptly take such
action as may be necessary to duly discharge and satisfy in full (i) all
Lessor's Liens attributable to the Owner Trustee in its individual capacity and
(ii) any other Liens attributable to the Owner Trustee in its individual
capacity on any part of the Trust Estate or the Indenture Estate which result
from claims against the Owner Trustee in its individual capacity not related to
the ownership of the Aircraft, the administration of the Trust Estate or the
Indenture Estate or the transactions contemplated by the Operative Documents or
the Pass Through Trust Documents. The Owner Trustee, in its individual capacity,
hereby agrees to indemnify and hold harmless the Lessee, the Indenture Trustee,
the Liquidity Provider, the Loan Trustee, the Subordination Agent and each Pass
Through Trustee from and against any loss, cost or expense (including reasonable
legal fees and expenses) which may be suffered or incurred by any of them as a
result of the failure of the Owner Trustee to discharge and satisfy any such
Lessor's Lien or other lien or encumbrance.

         (d) Each of the Owner Participant and the Owner Trustee (in its
individual capacity and as Owner Trustee) agrees with the Lessee, the Indenture
Trustee, the Loan Trustee, the Subordination Agent and each Pass Through Trustee
that it will comply with all of the terms of the Trust Agreement (as the same
may hereafter be amended or supplemented from time to time in accordance with
the terms thereof) applicable to it in its respective capacity, the
noncompliance with which would adversely affect any such party and shall not
take any action, or cause any action to be taken, which would amend, modify or
supplement any provision of the Trust Agreement in a manner adversely affecting
any such party without the prior written consent of such party, which consent
shall not be unreasonably withheld. The Owner Trustee confirms for the benefit
of the Lessee, the Loan Trustee and each Noteholder that it will comply with the
provisions of Article IV of the Trust Agreement. The Owner Participant agrees
not to terminate or revoke the trust created by the Trust Agreement without the
prior written consent of the

                                       44
                          AA-Boeing EETC-Leased Aircraft Participation Agreement
<PAGE>

Lessee and (so long as the Indenture shall not have been discharged) the Loan
Trustee and the Subordination Agent, which consent in the case of the Lessee
shall not be unreasonably withheld. The Owner Participant further agrees not to
remove the institution acting as Owner Trustee, and not to replace the
institution acting as Owner Trustee in the event that such institution resigns
as Owner Trustee, unless the Owner Participant shall have consulted in good
faith with the Lessee and the Loan Trustee prior to such removal or replacement
as to the identity, location and fee schedules of the proposed successor
trustee, provided that (i) the Owner Participant shall retain the right,
notwithstanding any such consultation, to act in its sole discretion (provided
that the Owner Participant shall not choose a replacement Owner Trustee which,
in the good faith opinion of the Lessee, may result in additional liability to
the Lessee pursuant to Section 10(c) hereof, except in the case of a mandatory
or voluntary resignation of the Owner Trustee where the Lessee has not proposed
an alternative Owner Trustee which is reasonably satisfactory to the Owner
Participant) and (ii) no such consultation with the Lessee shall be required if
an Event of Default shall have occurred and be continuing. The Owner Trustee and
the Owner Participant agree that no co-trustee or separate trustee shall be
appointed pursuant to Section 9.2 of the Trust Agreement without the Lessee's
(so long as no Event of Default shall have occurred and be continuing) prior
written consent, such consent not to be unreasonably withheld. The Owner
Participant agrees that if, at any time, so long as no Event of Default has
occurred and is continuing, the Lessee certifies that the Lessee has, or in the
good faith opinion of the Lessee will, become obligated to pay an amount
pursuant to Section 10(c) hereof and the amount that has or will become payable
would be reduced or eliminated if the situs of the Trust Estate were changed and
if, as a consequence thereof, the Lessee requests that the situs of the trust be
moved to another state in the United States from the state in which it is then
located, the Owner Participant shall direct such change in situs of the Trust
Estate as may be specified in writing by the Lessee and the Owner Participant
will, at the Lessee's sole cost and expense, take whatever action as may be
reasonably necessary to accomplish such change; provided that the Lessee shall
provide such additional indemnification for Taxes imposed by the jurisdiction to
which the Trust Estate is to be moved as the Owner Participant may reasonably
request. The Loan Trustee shall, at the Lessee's sole cost and expense, execute
such documents and take such action as may be necessary to effect such change in
the situs of the Trust Estate; provided that the Lien created by the Indenture
shall continue to be perfected and shall not be otherwise adversely affected by
such change.

         (e) [Intentionally left blank];

         (f) The Subordination Agent and each Pass Through Trustee hereby
unconditionally agrees to perform its respective obligations under the Indenture
(including, without limitation, those contained in Section 9.12 of the
Indenture) as though such obligations were fully set forth herein.

                                       45
                          AA-Boeing EETC-Leased Aircraft Participation Agreement
<PAGE>

         (g) The Owner Trustee, in its capacity as Owner Trustee, will not incur
any indebtedness for money borrowed, or enter into any business or other
activity, except as contemplated hereby and by the other Operative Documents.

         (h) The Loan Trustee in its individual capacity hereby unconditionally
agrees with and for the benefit of the parties to this Agreement that the Loan
Trustee in its individual capacity or as Loan Trustee will not directly or
indirectly create, incur, assume or suffer to exist any Liens on or against any
part of the Trust Estate, the Indenture Estate or the Aircraft arising out of
any act or omission of or claim against the Loan Trustee in its individual
capacity, and the Loan Trustee in its individual capacity agrees that it will at
its own cost and expense promptly take such action as may be necessary duly to
discharge and satisfy in full (i) all such Liens attributable to the Loan
Trustee in its individual capacity and (ii) any other liens or encumbrances
attributable to the Loan Trustee in its individual capacity on any part of the
Trust Estate or the Indenture Estate which result from claims against the Loan
Trustee in its individual capacity not related to the administration of the
Indenture Estate. The Loan Trustee hereby agrees to indemnify and hold harmless
the Lessee, the Owner Trustee, the Owner Participant, each Pass Through Trustee,
the Liquidity Provider and the Subordination Agent from and against any loss,
cost or expense (including reasonable legal fees and expenses) which may be
suffered or incurred by any of them as a result of the failure of the Loan
Trustee to discharge and satisfy any such Lien or such other lien or
encumbrance.

         (i) The Owner Trustee agrees that any profit, income, interest,
dividend or gain realized upon the maturity, sale or other disposition of any
Permitted Investment made by the Loan Trustee pursuant to Section 9.07 of the
Indenture, and paid to the Lessee on behalf of the Owner Trustee by the Loan
Trustee in accordance with the terms of such Section 9.07, shall be entirely for
the account of, and the sole property of, the Lessee who, for such purposes,
shall not be deemed to be acting as agent of the Owner Trustee, and the Lessee
shall have no obligation to pay over such income, interest, dividend or gain to
the Owner Trustee.

         (j) The Loan Trustee, and by its acceptance of an Equipment Note, each
holder thereof (or each Pass Through Trustee, so long as the relevant Pass
Through Trust Supplement is in effect) hereby waives to the fullest extent
permitted by law the benefit of the provisions of Section 1111(b) of Title 11 of
the United States Code to the extent such provisions give recourse against the
Owner Trustee (in its individual capacity) and the Owner Participant on account
of any amount payable as principal of, Make-Whole Amount, if any, and interest
on the Equipment Notes. If (i) all or any part of the Trust Estate becomes the
property of, or the Owner Participant becomes, a debtor subject to the
reorganization provisions of the Bankruptcy Reform Act of 1978 or any successor
provision, (ii) pursuant to such reorganization provisions the Owner Trustee (in
its individual capacity) or the Owner Participant is required, by reason of the
Owner Trustee (in its individual capacity) or the Owner Participant being held
to have recourse liability

                                       46
                          AA-Boeing EETC-Leased Aircraft Participation Agreement
<PAGE>

to a holder of an Equipment Note, a Pass Through Trustee or the Loan Trustee,
directly or indirectly, to make payment on account of any amount payable as
principal, Make-Whole Amount, if any, or interest on the Equipment Notes and
(iii) such holder, such Pass Through Trustee or the Loan Trustee actually
receives any Excess Payment (as hereinafter defined) which reflects any payment
by the Owner Trustee (in its individual capacity) or the Owner Participant on
account of (ii) above, then such holder, such Pass Through Trustee or the Loan
Trustee shall promptly refund to the Owner Trustee or the Owner Participant
(whichever shall have made such payment) such Excess Payment. For purposes of
this Section 12(j), "Excess Payment" means the amount by which such payment
exceeds the amount which would have been received by such holder, such Pass
Through Trustee or the Loan Trustee if the Owner Trustee (in its individual
capacity) or the Owner Participant had not become subject to the recourse
liability referred to in clause (ii) above. Nothing contained in this Section
12(j) shall prevent any holder of an Equipment Note, any Pass Through Trustee or
the Loan Trustee from enforcing any personal recourse obligation (and retaining
the proceeds thereof) of the Owner Trustee (in its individual capacity) or the
Owner Participant under this Participation Agreement or the Indenture (and any
exhibits or annexes thereto).

         (k) [Intentionally left blank];

         (l) In connection with a foreign sublease, the Lessee at any time, upon
notice to the Loan Trustee, Owner Trustee and the Owner Participant, may cause
the Aircraft to be registered under the applicable statutes of any other country
in which a Permitted Sublessee could be based in the name of the Owner Trustee
or, if required by applicable law, in the name of any other Person, and the
Owner Trustee and the Owner Participant will cooperate with the Lessee's
reasonable requests in effecting such foreign registration. Such foreign
registration is subject to the satisfaction of the conditions below or waiver
thereof by the Owner Trustee:

                           (i) no Specified Default or Event of Default shall
                  have occurred and be continuing at the date of such request or
                  at the effective date of the change in registration; provided
                  that it shall not be necessary to comply with this condition
                  (i) if the change in registration involves the re-registration
                  of the Aircraft under the laws of the U.S.;

                           (ii) all necessary governmental approvals required
                  for the subleased Airframe or any Engine to be imported into
                  the applicable country shall have been obtained prior to
                  commencement of any such sublease and any foreign exchange
                  permits necessary to allow all rent and other payments
                  provided for under any sublease shall be in full force and
                  effect;

                                       47

<PAGE>

                           (iii) each of the Owner Trustee, the Owner
                  Participant and the Loan Trustee, shall have received a legal
                  opinion addressed to it from counsel to the Lessee reasonably
                  satisfactory to such Persons (x) to the effect that (A) after
                  giving effect to such change in registration, all filing,
                  recording or other action necessary to perfect and protect the
                  Owner Trustee's rights and interests in and to the Aircraft
                  and the Lease has been accomplished and solely in the case of
                  the Loan Trustee, after giving effect to such change in
                  registration, the Lien on the Aircraft and the other property
                  included in the Indenture Estate shall continue as a valid and
                  duly perfected Lien and that all filing, recording or other
                  action necessary to perfect and protect the Lien of the
                  Indenture has been accomplished (or if such opinion cannot be
                  given at the time by which the Owner Trustee, the Owner
                  Participant and the Loan Trustee have been requested to
                  consent to a change in registration, (1) the opinion shall
                  detail what filing, recording or other action is necessary and
                  (2) the Owner Trustee, the Owner Participant and the Loan
                  Trustee, shall have received a certificate from the Lessee
                  that all possible preparations to accomplish such filing,
                  recording and other action shall have been done, and such
                  filing, recording and other action shall be accomplished and a
                  supplemental opinion to that effect shall be delivered to the
                  Owner Trustee, the Owner Participant and the Loan Trustee on
                  or prior to the effective date of such change in
                  registration), (B) the terms of the Lease are legal, valid and
                  binding and enforceable in such jurisdiction (subject to
                  customary exceptions), and (C) it is not necessary for the
                  Owner Trustee or the Owner Participant to qualify to do
                  business in such jurisdiction or otherwise satisfy any other
                  applicable law, rule or regulation existing at the date of
                  such request (or if such opinion cannot be given, the opinion
                  shall detail what other existing law, rule or regulation must
                  be satisfied by the Owner Trustee or the Owner Participant, as
                  the case may be) solely as a result of the proposed
                  re-registration, and (D) the laws of such foreign jurisdiction
                  require fair compensation by the government of such
                  jurisdiction payable in a currency freely convertible into
                  United States dollars for the loss of use or of title to the
                  subleased equipment in the event of the requisition by such
                  foreign government of such use or title or the Lessee has
                  agreed to provide insurance covering the risk of requisition
                  of use or of title of the Aircraft by the government of such
                  country for so long as the Aircraft is registered under the
                  laws of such country, and (y) in addition, if such country is
                  not, at the time of re-registration, the U.S. or a Permitted
                  Country to the effect that there exist no possessory rights in
                  favor of the Lessee under the laws of such country that would,
                  assuming at such time the Lessee is not insolvent or bankrupt,
                  prevent the return of the Aircraft in accordance with and when
                  permitted by the terms of the Lease upon the exercise by the
                  Owner Trustee of its remedies under the Lease;

                           (iv) the Owner Trustee the Owner Participant and the
                  Loan Trustee, shall have received assurances reasonably
                  satisfactory to the Owner Trustee, the Owner Participant and
                  the Loan Trustee, that the insurance provisions of the Lease
                  shall have been complied with after giving effect to such
                  change in registration;

                           (v) such re-registration will not result in the
                  imposition by such country of any taxes on the Owner Trustee,
                  the Owner Participant and the Loan Trustee, for which the
                  Lessee is not required to indemnify the Owner Trustee, the
                  Owner Participant and the Loan Trustee, unless the Lessee
                  agrees to indemnify the Owner Trustee, the Owner Participant
                  and the Loan Trustee, for any taxes imposed by such country in
                  connection with or relating to the transactions contemplated
                  by the Operative Documents that would not have been imposed
                  but for such re-registration; provided that it shall not be
                  necessary to comply with the conditions contained in this
                  clause (v) if such change in registration results in the
                  re-registration of the Aircraft under the laws of the U.S.,
                  except to the extent that the provisions of the tax
                  indemnification provisions relating to the Owner Participant
                  were amended in effecting a previous foreign registration;

                           (vi) such re-registration will not divest the Owner
                  Trustee of title to the Aircraft or adversely affect the Lien
                  of the Indenture; and

                           (vii) the Lessee shall have paid or made provision
                  for the payment of all reasonable out-of-pocket expenses
                  (including reasonable attorneys' fees) of the Owner Trustee,
                  the Owner Participant and the Loan Trustee, in connection with
                  such change in registration; provided further that the Lessee
                  shall not cause the Aircraft to be registered under the laws
                  of any foreign jurisdiction without the prior written consent
                  of the Owner Participant, if (A) the civil aviation laws of
                  such foreign jurisdiction impose unusual requirements or
                  liabilities on lessors of civil aircraft, and (B) the Owner
                  Participant would be required to comply with such requirements
                  or suffer such liabilities upon the registration of the
                  Aircraft in such foreign jurisdiction, and compliance
                  therewith or acceptance of such liabilities by the Owner
                  Participant would result in a material burden on the business
                  activities of the Owner Participant.

         (m) Each of the Loan Trustee and the Pass Through Trustee hereby
agrees, subject to the terms of Section 12(l) hereof, for the benefit of the
Lessee, to cooperate with the Lessee in effecting any foreign registration of
the Aircraft pursuant to Section 7(a)(i) of the Lease.

<PAGE>

         (o) The Owner Participant agrees that in each instance in which the
Lease provides that title to the Aircraft, Airframe, any Engine, engine, Part or
Obsolete Part shall be transferred to or vest in the Lessee, title to such
Aircraft, Airframe, Engine, engine, Part or Obsolete Part shall vest in the
Lessee, free and clear of all right, title and interest of the Owner Participant
and of Lessor's Liens, and the Owner Participant shall do all acts necessary to
discharge all of such Liens and other rights held by it in such Aircraft,
Airframe, Engine, engine, Part or Obsolete Part.

         (p) Each of the Loan Trustee and the Pass Through Trustee severally
agrees for the benefit of the Lessee that (i) it shall comply with Section 5.01
of the Indenture and (ii) in each instance in which the Lease provides that
title to any Part or Obsolete Part shall be transferred to or vest in the
Lessee, title to such Part or Obsolete Part shall vest in the Lessee, free and
clear of all Liens attributable to it and other rights held by it, and the Loan
Trustee and the Pass Through Trustee, as applicable, shall do all acts necessary
to discharge all of its Liens and other rights held by it in such, Part or
Obsolete Part.

         (q) The Owner Trustee, in its individual capacity, hereby agrees that
it will perform all of its administrative duties under this Agreement and the
other Operative Documents (whether in its individual capacity or as Owner
Trustee) solely in the State of Utah, except to the extent necessary to exercise
any of its rights or remedies to the extent permitted by applicable laws in
connection with an Event of Default or an event that with notice or lapse of
time or both would become an Event of Default.

         (r) With respect to any transfer of Equipment Notes, the Loan Trustee
and the Owner Trustee agree for the benefit of the Lessee, to comply with the
provisions of Section 2.04 of the Indenture.

         (s) [Intentionally left blank].

         (t) Each of State Street, the Loan Trustee, the Owner Participant, the
Original Loan Participant, the Subordination Agent, each Pass Through Trustee
and any other holder of an Equipment Note, covenants that, except as expressly
permitted under Section 15 of the Lease following an Event of Default that has
occurred and is continuing, neither it, nor any Person claiming through or under
it, will take or cause to be taken any action inconsistent with the Lessee's
rights under the Lease and its right to quiet enjoyment of, or otherwise
interrupt or interfere in any way with continuing possession, use or operation
of, the Aircraft, the Airframe or any Engine by the Lessee or any sublessee,
assignee or transferee under any sublease, assignment or transfer then in effect
and permitted by the terms of the Lease; provided that the existence of any
event or condition that constitutes or was caused by or resulting from, any TWA
Matter, shall not constitute a breach of this covenant by any such party.

<PAGE>

         (u) The Loan Trustee, the Pass Through Trustee and the Subordination
Agent hereby acknowledge and agree with the Owner Trustee that for purposes of
Section 8.01(j) of the Indenture no Owner Participant Guaranty shall be
considered to "cease[] to be a valid and enforceable obligation of the Owner
Participant Guarantor" to the extent such Owner Participant Guarantor is
released from its obligations thereunder pursuant to the last sentence of
Section 19(c).

         (v) In the event the Debt Rate is increased pursuant to Section 2(d) of
the Registration Rights Agreement and such increase remains in effect for more
than one Lease Period, the Lessee, the Owner Trustee and the Owner Participant
agree to make corresponding adjustments to the Termination Values and Stipulated
Loss Values for the Aircraft set forth in Schedule B to the Lease, to take into
account such increase of the Debt Rate, in a manner consistent with the
preparation of such Schedule to the Lease as was in effect as of the Closing
Date, provided that such adjustment shall only be effective for so long as such
increased Debt Rate remains in effect.

         SECTION 13. Other Documents. The Owner Participant agrees to comply
with all of the terms of the Trust Agreement (as the same may hereafter be
amended from time to time in accordance with the terms thereof) applicable to it
and with Sections 7, 9, 11, 12 and 15 of the Lease. The Lessee hereby consents
in all respects to the execution and delivery of the Indenture and to all of the
terms thereof, and the Lessee acknowledges receipt of an executed counterpart of
the Indenture. Notwithstanding the foregoing, the Loan Trustee and the Owner
Trustee hereby agree for the benefit of the Lessee that the Indenture and the
Pass Through Trust Documents shall not be amended, modified or supplemented
without the prior written consent of the Lessee if such amendment, modification
or supplement would adversely affect the Lessee. The Loan Trustee and the Owner
Trustee agree to furnish promptly to the Lessee copies of any amendment,
modification or supplement to any Operative Document to which the Lessee is not
a party to the extent the Indenture Trustee or the Owner Trustee, as the case
may be, shall have in its possession a copy of such amendment, modification or
supplement.

         SECTION 14. [Intentionally left blank]

         SECTION 15. Liabilities of the Owner Participant and the Original Loan
Participants. Neither the Owner Participant nor any Original Loan Participant
shall have any obligation or duty to the Lessee with respect to the transactions
contemplated hereby except those obligations or duties expressly set forth in
this Agreement or, in the case of the Owner Participant, the Tax Indemnity
Agreement. Without limiting the generality of the foregoing, under no
circumstances whatsoever shall the Owner Participant, as such, or any Original
Loan Participant, as such, be liable to the Lessee for any action or inaction on
the part of the Owner Trustee or the Loan Trustee in connection with the
Indenture, the Trust Agreement, the Lease, the Aircraft, the administration of
the Trust Estate or the Indenture Estate or otherwise, whether or not such
action or inaction is

                          AA-Boeing EETC-Leased Aircraft Participation Agreement
<PAGE>

caused by the willful misconduct or gross negligence of the Owner Trustee or the
Loan Trustee unless such action or inaction is at the direction of the Owner
Participant (in the case of action or inaction on the part of the Owner Trustee)
or such Original Loan Participant (in the case of action or inaction on the part
of the Loan Trustee).

         SECTION 16. Certain Covenants of the Lessee. The Lessee covenants and
agrees with the Owner Participant, each Pass Through Trustee, the Loan Trustee
and the Owner Trustee as follows:

         (a) From and after the Closing Date, the Lessee will cause to be done,
executed, acknowledged and delivered all and every such further acts,
conveyances and assurances as the Owner Trustee, the Owner Participant, each
Pass Through Trustee or the Loan Trustee shall require for accomplishing the
purposes of this Agreement and the other Operative Documents and the Pass
Through Trust Documents, which further acts, conveyances and assurances shall
otherwise be consistent with this Agreement, the other Operative Documents and
the Pass Through Trust Documents. The Lessee shall cause the Aircraft to be duly
registered, and at all times to remain duly registered, in the name of the Owner
Trustee, except as otherwise required or permitted hereunder or under the Lease,
under the Transportation Code, or shall furnish to the Owner Trustee such
information as may be required to enable the Owner Trustee to make application
for such registration, and shall promptly furnish to the Owner Trustee such
information as may be required to enable the Owner Trustee to timely file any
reports required to be filed by it as the Lessor under the Lease or as the owner
of the Aircraft with any governmental authority because of the Owner Trustee's
ownership of the Aircraft.

         (b) The Lessee will cause the Lease covering the Aircraft, the Trust
Agreement and the Indenture covering the Aircraft to be promptly filed and
recorded, or filed for recording, to the extent permitted under the
Transportation Code, and the rules and regulations of the FAA thereunder, or
required under any other applicable law.

         (c) The Lessee will furnish to the Owner Trustee and the Loan Trustee
annually after the execution hereof (but not later than March 15th of each
year), commencing with the year 2002, an opinion of Crowe & Dunlevy, P.C., or
other counsel reasonably acceptable to the Owner Trustee and the Loan Trustee,
stating either:

                           (i) that in the opinion of such counsel such action
                  has been taken with respect to the recording, filing,
                  re-recording and refiling of the Lease, the Indenture, the
                  Trust Agreement and any supplements thereto, including any
                  financing or continuation statements, and such other filings
                  and recordings as is necessary to maintain, for the 15-month
                  period succeeding the date of such opinion, the rights and
                  interests of the Owner Trustee in and to the Aircraft, and,
                  with respect to the Indenture, the

                                       52

                  perfection of the security interests created thereby and
                  reciting the details of such action; or

                           (ii) that in the opinion of such counsel no such
                  action is necessary to maintain, for the 15-month period
                  succeeding the date of such opinion, the perfection of such
                  rights and interests.

         (d) The Lessee shall at all times maintain its corporate existence
except as permitted by Section 16(e) hereof. The Lessee will do or cause to be
done all things necessary to preserve and keep in full force and effect its
rights (charter and statutory) and franchises; provided, however, that the
Lessee shall not be required to preserve any right or franchise if its Board of
Directors shall determine that the preservation thereof is no longer desirable
in the conduct of the business of the Lessee. Notwithstanding the proviso to the
immediately preceding sentence, the Lessee shall, for so long as and to the
extent required under Section 1110 of the Bankruptcy Code in order that the
Owner Trustee and the Loan Trustee be entitled to the benefits of Section 1110
of the Bankruptcy Code with respect to the right to repossess the Airframe,
Engines and Parts as provided in the Lease, remain a Certificated Air Carrier.

         (e) The Lessee shall not consolidate with or merge into any other
corporation or convey, transfer or lease all or substantially all of its assets
as an entirety to any Person, unless:

                           (i) the person formed by such consolidation or into
                  which the Lessee is merged or the Person that acquires by
                  conveyance, transfer or lease all or substantially all of the
                  assets of the Lessee as an entirety (the "Successor"): shall,
                  if and to the extent required under Section 1110 of the
                  Bankruptcy Code in order that the Owner Trustee, the Owner
                  Participant and the Loan Trustee continue to be entitled to
                  any benefits of Section 1110 with respect to the Aircraft, be
                  a Certificated Air Carrier; and shall execute and deliver to
                  the Owner Trustee, the Owner Participant, and the Loan Trustee
                  an agreement in form reasonably satisfactory to such Persons
                  containing an assumption by such Successor of the due and
                  punctual performance and observance of each covenant and
                  condition of each of the Operative Documents to which the
                  Lessee is a party and each other Operative Document to which
                  the Lessee is a party, to be performed or observed by the
                  Lessee;

                           (ii) immediately after giving effect to such
                  transaction, no Specified Default or Event of Default shall
                  have occurred and be continuing; and

                                       53
                          AA-Boeing EETC-Leased Aircraft Participation Agreement
<PAGE>

                           (iii) the Lessee shall have delivered to the Owner
                  Trustee, the Owner Participant and the Loan Trustee an
                  officer's certificate and an opinion of counsel (which may be
                  American's general counsel), each stating that such
                  consolidation, merger, conveyance, transfer or lease and the
                  assumption agreement described in clause (i) above comply with
                  this Section 16(e) and that all conditions precedent herein
                  provided for relating to such transaction have been complied
                  with (except that such opinion need not cover the matters
                  referred to in clause (ii) above and may rely, as to factual
                  matters, on an officer's certificate of the Lessee) and, in
                  the case of such opinion, that such assumption agreement has
                  been duly authorized, executed and delivered by the Successor,
                  constitutes its legal, valid and binding obligation and is
                  enforceable against such Successor in accordance with its
                  terms, except as the same may be limited by applicable
                  bankruptcy, insolvency, reorganization, moratorium or similar
                  laws affecting the rights of creditors generally and by
                  general principles of equity.

Upon any consolidation or merger, or any conveyance, transfer or lease of all or
substantially all of the assets of the Lessee as an entirety in accordance with
this Section 16(e), the Successor shall succeed to, be substituted for, and may
exercise every right and power of and shall assume every obligation and
liability of, the Lessee under this Agreement and the other Operative Documents
and Pass Through Trust Documents with the same effect as if the Successor had
been named as the Lessee herein provided that in no event will any such
conveyance release the transferor Lessee from any liability to the extent caused
by any breach existing at the time of such conveyance by the Lessee of any of
its representations, warranties, covenants or obligations contained herein or in
the Lease. No such conveyance, transfer or lease of all or substantially all of
the assets of the Lessee shall have the effect of releasing the Lessee or any
successor which shall theretofore have become such in the manner prescribed in
this Section 16(e) from its liability hereunder or under any other Operative
Document to which it is a party. The Lessee shall not assign its rights and
obligations under this Agreement and the other Operative Documents without the
prior written consent of the Owner Trustee and the Loan Trustee; provided,
however, that so long as the Equipment Notes have been repaid in full, no such
consent shall be required for any assignment by the Lessee to any Affiliate
thereof that is a Certificated Air Carrier and the obligations of which under
the Operative Documents have been guaranteed by American in form reasonably
satisfactory to the Owner Participant. 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 Lease.

         (f) The provisions of Sections 17 and 22 of the Lease are hereby
incorporated by reference herein for the express benefit of each Pass Through
Trustee. The Lessee shall notify the Loan Trustee and the Owner Trustee thirty
days prior to any change in the

                                       54

location of the chief executive office of the Lessee. In the event the Aircraft
is requisitioned for use by the Government pursuant to the Civil Reserve Air
Fleet Program referred to in Section 7(b)(iv) of the Lease, the Lessee shall
provide the Owner Trustee and the Loan Trustee with the name and address of the
Contracting Office Representative for the Air Mobility Command of the United
States Air Force for notification as required under Section 15 of the Lease.

         SECTION 17. [Intentionally left blank]

         SECTION 18. Notices. Unless otherwise specifically provided herein, all
notices required under the terms and provisions of this Agreement shall be in
English and in writing, and any such notice may be given by United States
registered or certified mail, postage prepaid, courier service, telegram, telex,
telecopy, cable or facsimile (confirmed by telephone or in writing in the case
of notice by telegram, telex, telecopy, cable or facsimile) or any other
customary means of communication, and any such notice shall be effective when
delivered if to the Lessee, the Owner Participant, the Original Loan
Participant, the Owner Trustee, the Indenture Trustee, the Loan Trustee, the
Subordination Agent, each Pass Through Trustee or the Liquidity Provider, at
their respective addresses or telex or facsimile numbers set forth in Schedule I
to this Agreement, or to such other address or telex or facsimile number as such
party may hereafter specify for such purpose by notice to the other parties
hereto.

         SECTION 19. Certain Covenants of the Owner Participant.

         (a) [Intentionally left blank];

         (b) The Owner Participant agrees with and for the benefit of the other
parties to this Agreement that it will not directly or indirectly create, incur,
assume or suffer to exist any Lessor's Liens or Original Owner Participant's
Liens other than Lessor's Liens attributable to the Owner Trustee on or against
any part of the Trust Estate or the Aircraft arising out of any act or omission
of or claim against or affecting any part of the Trust Estate or the Aircraft
and agrees that it will, at its own cost and expense, take such action as may be
necessary to duly discharge and satisfy in full any such Lessor's Lien or
Original Owner Participant's Lien (by bonding or otherwise, so long as Lessee's
operation and use of the Aircraft is not impaired and the Lien of the Indenture
is not impaired), the Owner Participant hereby agrees to indemnify and hold
harmless the Lessee, the Liquidity Provider, the Loan Trustee, the Subordinated
Agent and each Pass Through Trustee against any loss, cost or expense (including
reasonable legal fees and expenses) which may be suffered or incurred by any of
them as the result of the failure of the Owner Participant to discharge and
satisfy any such Lessor's Lien or Original Owner Participant's Lien.

<PAGE>

         (c) The Owner Participant shall not assign, convey or otherwise
transfer any of its right, title or interest in and to all or any part of any of
the Operative Documents or the Trust Estate, except that the Owner Participant
may assign or otherwise transfer all (but not less than all) thereof to any
transferee, provided that (i) such transferee (x) is (A) a Citizen of the United
States or qualifies through a discretionary trust arrangement or similar
arrangement that is sufficient to permit registration of the Aircraft with the
FAA (without regard to any provision of applicable law that permits registration
of an aircraft by limiting its location and usage) and (B) a "United States
Person" (as defined in Section 7701(a)(30) of the Code) for Federal income tax
purposes, (y) has (or has its obligations guaranteed, pursuant to a guaranty
agreement substantially in the form attached hereto Exhibit XI or otherwise
reasonably satisfactory to the Lessee and the Loan Trustee, by a Person that
has) a tangible net worth of at least $50,000,000, and (z) has the requisite
power, authority and legal right to enter into and carry out the transactions
contemplated hereby; (ii) such transferee is not an airline or other commercial
operator of aircraft or any Affiliate of any thereof; (iii) such transferee is
(A) a bank, trust company, insurance company, pension trust, finance or leasing
company or other corporation or financial institution and is not a limited
liability company, partnership or similar entity (any such transferee being
referred to as an "Acceptable Entity"), (B) a limited liability company,
partnership or similar entity, all of the membership, partnership or similar
ownership interests (in any such case, an "Interest") of which are directly or
indirectly owned by not more than nine Persons, each of which (x) is an
Acceptable Entity and (y) is and will continue to be a "United States Person"
(as defined in Section 7701(a)(30) of the Code) for Federal income tax purposes
provided that (1) no transfer of any Interest by any Person which holds the same
shall violate the applicable provisions of the Securities Act or any other law,
as the case may be, or require registration under the Securities Act, and (2)
the holders of ownership interests in any Acceptable Entity shall not be taken
into account in determining the number of Persons indirectly owning Interests in
such limited liability company, partnership or similar entity; or (C) any other
entity approved by the Lessee, such approval not to be unreasonably withheld
(any transferee described in clause (A), (B) or (C), an "Acceptable Person");
(iv) such transfer does not violate the applicable provisions of the Securities
Act or any other law, as the case may be, or require registration under the
Securities Act; (v) such transferee assumes all obligations of the Owner
Participant under the Operative Documents to which the Owner Participant is a
party or by which the Owner Participant is bound pursuant to an agreement
substantially in the form attached hereto as Exhibit XIII or otherwise
reasonably satisfactory to the Lessee and the Loan Trustee; (vi) after giving
effect to such transfer, there will be no more than one Owner Participant; (vii)
the Owner Participant shall deliver the Lessee and the Loan Trustee an opinion
of counsel reasonably satisfactory to the Lessee and the Loan Trustee (it being
agreed that in-house counsel shall be deemed acceptable), that each of the
agreement referred to in clause (v) above and any guaranty delivered pursuant to
clause (i)(y) above has been duly authorized executed and delivered by such
transferee, in the case of such agreement, and by the guarantor, in the case of
any such guaranty, constitutes its legal, valid and binding

                                       56
                          AA-Boeing EETC-Leased Aircraft Participation Agreement
<PAGE>

obligation and is enforceable against such transferee in accordance with its
terms, except as the same may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting the rights of creditors
generally or by general principles of equity; (viii) the Owner Participant shall
deliver to the Lessee and the Loan Trustee one or more certificates of a duly
authorized officer of the transferor and, if necessary, transferee Owner
Participant containing, when taken together, representations and warranties
addressing all of the matters contained in clauses (i), (iii) and (vi) of this
paragraph (c) and an opinion delivered by counsel of the type referred to in
clause (vii) of this paragraph (c) to the effect that such transfer (A) complies
with the provisions of clause (i)(z) of this paragraph (c) and (B) does not
require registration under the Securities Act (it being understood that such
counsel may assume such facts as such counsel deems reasonably necessary in
order to deliver the opinion referred to in clause (B) of this clause (viii));
and (ix) the Owner Participant pays all reasonable expenses of the Owner
Trustee, the Loan Trustee, the Pass Through Trustee the Lessee and the other
parties hereto in connection with such transfer; and provided, further, that
unless such transferee is Boeing or an Affiliate thereof, the Owner Participant
may not transfer its interest until one month after the Closing Date. If the
Owner Participant intends to transfer its interests hereunder, it shall give
prior written notice thereof as soon as practicable, but in no event less than
10 Business Days prior thereto, to the Lessee and the Loan Trustee, specifying
the name and address of the proposed transferee. The Owner Participant may at
any time grant participations in its interest in the Operative Documents to any
person on customary terms so long as no such participant shall be an Owner
Participant of record, such grant complies with clauses (i)(x), (ii), (iv) and
(ix) above, and the transferring Owner Participant makes the representation and
warranty described in Section 4(j) of the form of assignment and assumption
agreement attached hereto as Exhibit XIII.

         Any agreement or instrument pursuant to which the Owner Participant
sells such a participation shall provide that the Owner Participant shall retain
the sole right to exercise the rights of the "Owner Participant" pursuant to the
Operative Documents.

         In connection with any transfer by the Owner Participant of its
interest in the Trust Estate in compliance with this Section 19(c), any Owner
Participant Guarantor which delivered an Owner Participant Guaranty in respect
of the obligations of the transferring Owner Participant shall be released from
its obligations under such Owner Participant Guaranty.

         SECTION 20. Right to Restructure.

         (a) Back-leveraging. So long as the Equipment Notes have been repaid in
full, the Owner Participant will be permitted to grant a security interest in
the Lease or "back-leverage" the transaction to a third party, provided that (i)
no such grant or "back-leveraging" will require any participation by the Lessee,
(ii) such third party agrees to

                                       57
                          AA-Boeing EETC-Leased Aircraft Participation Agreement
<PAGE>

preserve the Lessee's quiet enjoyment of the Aircraft, (iii) the Owner
Participant pays all reasonable expenses of the other parties to the Operative
Documents in connection with such grant or "back-leveraging", (iv) such grant or
"back-leveraging" does not violate the Securities Act or any other law, as the
case may be, or require registration under the Securities Act or, without the
Lessee's consent (such consent not to be unreasonably withheld), involve a Rule
144A/Reg S or other capital markets transaction, (v) none of the obligations,
liabilities and risks of the Lessee in the use and operation of the Aircraft or
under or in respect of the Lease shall be increased, and none of the Lessee's
rights and benefits in respect thereof shall be diminished, as a result of any
such grant or "back-leveraging", and the Owner Participant agrees to indemnify
the Lessee for any such adverse consequences resulting from such grant or
"back-leveraging", (vi) the Owner Participant pays any Make-Whole Amount
resulting from the redemption of the Equipment Notes and (vii) such transaction
is permitted under the Indenture.

         (b) Special Structure. So long as the Equipment Notes shall have been
repaid in full, Boeing or an Affiliate thereof shall have the right to
restructure the transaction contemplated herein using (i) a "cross border"
lease, a tax lease or a head-lease/sublease structure and (ii) any other type of
transaction, which may involve special structural arrangements other than
securitizations of the rent or the debt pursuant to an EETC or similar structure
in which the Lessee would act as issuer (any such structure described in
subclauses (i) and (ii) above, a "Special Structure"), provided that such
Special Structure shall satisfy the requirements of subclauses (ii)-(vii) of
Section 20(a) hereof. Any Special Structure may result in additional persons
participating in such transactions. The Lessee agrees to cooperate in the
implementation of any such restructuring and to take such action as may
reasonably be requested by Boeing to accomplish such restructuring, including
taking such actions as may be agreed by the parties acting reasonably taking
into account Market-Based Transactions for the type of Special Structure
selected. In any such Special Structure Boeing shall be entitled to retain all
the benefits of any such transaction. All transactional and incremental ongoing
costs and expenses incurred in connection with such Special Structure (including
reasonable fees and expenses of the Lessee's counsel) shall be borne by Boeing
and there shall be no change in the Lessee's scheduled rental payments.
Notwithstanding the foregoing, the Lessee shall not be required to enter into
any Special Structure if such Special Structure would materially increase,
individually or in the aggregate, the obligations of the Lessee under the
Operative Documents, or would require the Lessee to pay, directly or indirectly,
increased amounts of money in connection with such Special Structure, other than
de minimis increased amounts. Boeing shall provide the Lessee with such other
indemnification as the Lessee shall reasonably request in connection with such
Special Structure on terms to be agreed by the parties acting reasonably taking
into account Market-Based Transactions.

         (c) Except as described above in this Section 20(b), the Owner
Participant will have no other rights to restructure or refinance the
transaction, including without

                                       58
                          AA-Boeing EETC-Leased Aircraft Participation Agreement
<PAGE>

limitation to include a "head-lease" structure, without the Lessee's consent,
such consent not to be unreasonably withheld.

         (d) No provision in the preceding paragraphs of this Section 20 shall
be construed to limit the issuance, or the Owner Participant's right to effect
the issuance, of Series E Equipment Notes provided, that the Owner Participant
shall not cause the Owner Trustee to issue Series E Equipment Notes pursuant to
the Indenture, unless it shall have received Ratings Confirmation (as defined in
the Intercreditor Agreement). If Series E Equipment Notes are initially issued
to other than the Pass Through Trustee for the Class E Certificates, the Owner
Participant will cause the Owner Trustee to cause such Series E Equipment Notes
to be subject to the provisions of the Intercreditor Agreement that allow the
"Controlling Party" (as defined in the Intercreditor Agreement), during the
continuance of an "Indenture Event of Default" (as defined in the Intercreditor
Agreement), to direct the Loan Trustee in taking action under the Indenture.

         SECTION 21. [Intentionally left blank]

         SECTION 22. Concerning the Owner Trustee. Wells Fargo Bank Northwest,
National Association is entering into this Agreement solely in its capacity as
Owner Trustee under the Trust Agreement and not in its individual capacity
(except as expressly stated herein) and in no case shall Wells Fargo Bank
Northwest, National Association (or any entity acting as successor Owner Trustee
under the Trust Agreement) be personally liable for or on account of any of the
statements, representations, warranties, covenants or obligations stated to be
those of the Owner Trustee hereunder, provided, however, that Wells Fargo Bank
Northwest, National Association (or any such successor Owner Trustee) shall be
personally liable hereunder for its own gross negligence or willful misconduct
or for its breach of its covenants, representations and warranties contained
herein, to the extent covenanted or made in its individual capacity.

         SECTION 23. [Intentionally left blank]

         SECTION 24. Successor Loan Trustee; Amendment of Pass Through Trust
Documents.

         (a) In the event that the Loan Trustee gives notice of its resignation
pursuant to Section 9.08(b) of the Indenture, the Lessee may direct the Owner
Trustee to appoint, and the Owner Trustee shall promptly appoint, a successor
Loan Trustee.

         (b) In the event that either the Owner Trustee or the Lessee obtains
knowledge of the existence of any of the grounds for removal of the Loan Trustee
set forth in Section 9.08 of the Indenture, the Owner Trustee or the Lessee, as
the case may be, shall promptly give notice (the "Removal Notice") to the other
by telephone, confirmed in writing. Within five Business Days after the giving
of the Removal Notice, the Lessee

                                       59
                          AA-Boeing EETC-Leased Aircraft Participation Agreement
<PAGE>

may direct the Owner Trustee to remove, and the Owner Trustee shall remove, the
Loan Trustee and appoint a successor Loan Trustee, provided that, if within ten
Business Days after the giving of the Removal Notice the Loan Trustee shall not
have been removed, the Owner Trustee shall be deemed without further act to have
delegated to the Lessee the right, on behalf of the Owner Trustee, to remove the
Loan Trustee and appoint a successor, and, in the event of the removal of the
Loan Trustee in accordance with such delegation, the Lessee agrees to appoint
promptly a successor Loan Trustee.

         (c) The Lessee shall not enter into any modification or amendment of
(i) Section 3.01(g) of the Pass Through Trust Supplements or (ii) any Pass
Through Trust Documents in any manner affecting the Pass Through Trusts created
pursuant to the Pass Through Trust Supplements, in each case without the consent
of the Owner Participant, such consent not to be unreasonably withheld.

         SECTION 25. Miscellaneous.

         (a) Any capitalized term not herein defined, when used herein in
capitalized form, shall have the meaning attributed thereto in the Lease.

         (b) Nothing contained in this Agreement, or in the Lease, the
Indenture, the Trust Agreement or the Tax Indemnity Agreement shall be construed
as a guarantee by the Lessee of payments due pursuant to the Equipment Notes or
the Pass Through Certificates or of the residual value or useful life of the
Aircraft or any portion thereof.

         (c) Any provision of this Agreement which is prohibited and
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction. This Agreement may be executed by the parties hereto in
separate counterparts, each of, which when so executed and delivered shall be an
original, but all such counterparts shall together constitute but one and the
same instrument. Neither this Agreement nor any of the terms hereof may be
terminated, amended, supplemented, waived or modified orally, but only by an
instrument in writing signed by the party against which the enforcement of the
termination, amendment, supplement, waiver or modification is sought or to the
extent required by the Indenture, with the consent of each Pass Through Trustee.
The section and paragraph headings in this Agreement and the index preceding
this Agreement are for convenience of reference only and shall not modify,
define, expand or limit any of the terms or provisions hereof and all references
herein to numbered sections, unless otherwise indicated, are to sections of this
Agreement.

permitted assigns, the Loan Trustee and its successors as Loan Trustee under the
Indenture, the Owner Trustee and its successors as Owner Trustee under the Trust
Agreement, the Owner Participant and, subject to the provisions of Section 19(c)
hereof, its successors and permitted assigns, and the Original Loan Participant
and, the Noteholders. Each Noteholder other than the Original Loan Participant,
by its acceptance of any Equipment Note, shall be deemed to have irrevocably and
unconditionally agreed to perform the obligations of a Noteholder hereunder and
under the Indenture. No purchaser or holder of any Equipment Note (including any
Noteholder) shall be deemed to be a successor or assign of any of the Original
Loan Participants.

         (e) With respect to any opinion required to be delivered under any
Operative Document by counsel to any party hereto, each party hereto hereby
irrevocably instructs its applicable counsel to deliver such opinion to and for
the benefit of the parties that are the addressees of such opinion.

         (f) The Lessee, the Owner Participant, the Owner Trustee, the Indenture
Trustee, the Loan Trustee, the Pass Through Trustee, the Subordination Agent and
the Original Loan Participant shall keep the terms of this Participation
Agreement, the Original Participation Agreement, Schedule B to the Lease,

Participant's interest or their respective counsel or special counsel,
independent insurance brokers, auditors or other agents if such Persons shall
have agreed to hold such Confidential Information confidential in accordance
with the provisions set forth herein, (ii) to the Lessee's, the Owner
Participant's, the Owner Trustee's, the Indenture Trustee's, the Loan Trustee's,
the Pass Through Trustee's, the Subordination Agent's or the Original Loan
Participant's counsel or special counsel, independent insurance brokers,
auditors, or other agents, Affiliates or investors who agree to hold such
information confidential, (iii) to any Person with whom the Lessee or the Owner
Participant (or any Affiliate thereof) is in good faith conducting negotiations
relating to any restructuring, refinancing, transfer, sale, assignment or other
disposition of rights and interest permitted under the terms of this
Participation Agreement, if such Persons shall have agreed to hold such
Confidential Information confidential in accordance with the provisions set
forth herein, (iv) as may be required by any order of any court or
administrative agency or by any statute, rule, regulation or order of any
governmental authority (the "Court Order"); provided that if any party (such
party, the "Disclosing Party") is required by such a Court Order to disclose any
Confidential Information, the Disclosing Party will promptly notify the other
party (such other party, the "Non-Disclosing Party") prior to such disclosure to
enable the Non-Disclosing Party to seek a

reasonable discretion deems appropriate, and the Disclosing Party will cooperate
with the Non-Disclosing Party in its efforts to obtain a protective order or
other reasonable assurance that confidential treatment will be accorded the
Confidential Information and (v) to such other Persons as are reasonably deemed
necessary by the disclosing party in order to protect the interests of such
party or for the purposes of enforcing such documents by such party; provided
that any and all disclosures permitted by clauses (iii), (iv) or (v) above shall
be made only to the extent necessary to meet the specific requirements or needs
of the Persons making such disclosures. Each party shall in each instance obtain
the prior written approval of each party concerning the exact text and timing of
news releases, articles and other informational releases to the public media
concerning the transaction governed by this Participation Agreement.

         (g) Each of the Lessee, the Owner Participant, the Owner Trustee, the
Indenture Trustee, the Loan Trustee, the Pass Through Trustee and the
Subordination Agent covenant that until the Series A-1 Equipment Notes and
Series A-2 Equipment Notes have been paid in full, it shall not file an
involuntary bankruptcy petition or initiate any other form of insolvency
proceeding against the respective Pass Through Trust holding such Equipment
Notes.

THIS AGREEMENT HAS BEEN DELIVERED IN THE STATE OF NEW YORK AND SHALL IN ALL
RESPECTS BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE
OF NEW YORK, INCLUDING ALL MATTERS OF CONSTRUCTION, VALIDITY AND PERFORMANCE.

         (5) Airworthiness Directives and Mandatory Regulations. All FAA
airworthiness directives and U.S. Federal Aviation Regulations applicable to the
Aircraft (including its systems and components) requiring compliance or
terminating compliance on or prior to the expiration of the Lease Term (or, if
Lessee has commenced compliance with such directive with respect to any other
aircraft affected by such directive and in use by Lessee and, subsequent to any
such commencement, the Aircraft is subjected to a maintenance check of the type
at which Lessee makes the modification required by such directive in accordance
with the Maintenance Program, requiring compliance or terminating compliance
within 12 months after the expiration of the Lease Term) shall be accomplished
in compliance with the FAA's specific instructions without regard to any
alternate means of compliance, waiver or operator exemptions that delay
compliance with such FAA airworthiness directives or U.S. Federal Aviation
Regulations. Lessee shall provide a current and accurate status report and all
hard copy records evidencing, when accomplished, times and cycles and methods of
accomplishment with the appropriate signatures or stamps.

         (6) RETURN STATUS.

                  (i) Operating Condition. At the expiration of the Lease Term,
         the Aircraft shall be in as good an operating and physical condition as
         when delivered to Lessee at the Commencement Time, ordinary wear and
         tear excepted, and shall be in such condition, and all modifications
         and maintenance of the Aircraft after the Commencement Time shall have
         been performed in such a manner, as to allow the Aircraft to be
         operated under Part 121 of the Federal Aviation Regulations.

                  (ii) "C-Check" Time Remaining. The Airframe shall have 100%
         remaining time (i.e., a full C-Check interval) until its next due
         "C-Check" under the Maintenance Program, as measured by hour, cycle or
         calendar day, whichever is applicable and more limiting; provided that
         Lessee may return the Aircraft with less than 100% remaining time,
         subject to paying the C-Check Adjustment Amount. The "C-Check
         Adjustment Amount" shall be calculated by multiplying (A) the
         difference between (I) the number of hours, cycles or calendar days, as
         applicable, in a full C-Check interval and (II) the number of hours,
         cycles or calendar days, as applicable, remaining until the next due
         C-Check by (B) a fraction (I) the numerator of which is the cost of
         completing the C-Check in accordance with the Maintenance Program (at
         Lessee's internal rates with no mark up) at the time of redelivery and
         (II) the denominator of which is the total number of hours, cycles or
         calendar days, as applicable, in the applicable C- Check interval.

                  (iii) Most Comprehensive Structural Refurbishment Time
         Remaining. The Airframe shall have at least 25% remaining time until
         its next scheduled most

                                        3
<PAGE>

         comprehensive structural refurbishment (referred to as a Heavy C-Check,
         under the American Airlines maintenance program, or a C4 or C8 (or a
         succeeding or subsequent check identified by the letter "C" and a
         multiple of the number "4"), under the TWA maintenance program)
         ("MCSR"), as measured by hour, cycle or calendar day, whichever is
         applicable and more limiting; provided that Lessee may return the
         Aircraft with less than 25% remaining time, subject to paying the MCSR
         Adjustment Amount. The "MCSR Adjustment Amount" shall be calculated by
         multiplying (A) the difference between (I) the number of hours, cycles
         or calendar days, as applicable, representing 25% remaining time until
         the next MCSR and (II) the number of hours, cycles or calendar days, as
         applicable, remaining until the next due MCSR by (B) a fraction (I) the
         numerator of which is the cost of completing the MCSR in accordance
         with the Maintenance Program (at rates determined by a mutually agreed
         third party) at time of redelivery and (II) the denominator of which is
         the total number of hours, cycles or calendar days, as applicable, in
         the applicable MCSR interval.

                  (iv) Landing Gear Time Remaining. The installed nose and main
         landing gears (the "Landing Gear") shall have at least 25% remaining
         time until the next scheduled overhaul under the Maintenance Program as
         measured by hour, cycle or calendar day, whichever is applicable and
         more limiting; provided that Lessee may return the Aircraft with less
         than 25% remaining time, subject to paying the Landing Gear Adjustment
         Amount. The "Landing Gear Adjustment Amount" shall be calculated by
         multiplying (A) the difference between (I) the number of hours, cycles
         or calendar days, as applicable, representing 25% remaining time until
         the next Landing Gear overhaul and (II) the number of hours, cycles or
         calendar days, as applicable, remaining until the next due Landing Gear
         overhaul by (B) a fraction (I) the numerator of which is the cost of
         completing the Landing Gear overhaul in accordance with the Maintenance
         Program (at rates determined by a mutually agreed third party) at time
         of redelivery and (II) the denominator of which is the total number of
         hours, cycles or calendar days, as applicable, in the applicable
         Landing Gear overhaul interval.

                  (v) Engine Life-Limited Part Cycle Life Remaining. Each
         life-limited part ("LLP") of the Engines returned with the Aircraft
         shall have at least 25% remaining of its total cycle life until
         required replacement under the Maintenance Program; provided that
         Lessee may return the Aircraft with less than 25% remaining life on an
         Engine LLP, subject to (i) such Engine LLP having a minimum of 1000
         cycles remaining until the next scheduled replacement and (ii) paying
         the Engine LLP Adjustment Amount. The "Engine LLP Adjustment Amount"
         shall be calculated by multiplying (A) the difference between (I) the
         number of cycles representing 25% remaining time until the next
         required replacement for such Engine LLP and (II) the number of cycles
         remaining until the next required replacement for such Engine LLP by
         (B) a fraction (I) the

                                        4
<PAGE>

         numerator of which is the price of replacing the relevant part with a
         new part pursuant to the Engine manufacturer's new part price listing
         in effect at the time of return of the Aircraft and (II) the
         denominator of which is the number of cycles in the new part's total
         life.

                  (vi) Engines Time Remaining. Each Engine returned with the
         Aircraft will have at least 25% remaining time under the Maintenance
         Program until the next required performance restoring major
         refurbishment (based on Lessee's mean time between such refurbishments
         for engines of the same type operated by Lessee) as measured by hour,
         cycle or calendar day, whichever is applicable and more limiting;
         provided that Lessee may return the Aircraft with less than 25%
         remaining time on an Engine, subject to (i) such Engine having a
         minimum of twelve months or 1000 cycles, whichever is more limiting,
         remaining until the next scheduled performance restoring major
         refurbishment under the Maintenance Program and (ii) paying the Engine
         Major Refurbishment Adjustment Amount. The "Engine Major Refurbishment
         Adjustment Amount" shall be calculated by multiplying (A) the
         difference between (I) the number of hours, cycles or calendar days, as
         applicable, representing 25% remaining time until the next required
         major refurbishment of such Engine and (II) the number of hours, cycles
         or calendar days, as applicable, remaining until the next required
         major refurbishment for such Engine by (B) a fraction (I) the numerator
         of which is the cost of completing the major engine refurbishment in
         accordance with the Maintenance Program (at rates determined by a
         mutually agreed third party) and (II) the denominator of which is the
         number of hours, cycles or calendar days, as applicable, in the
         applicable major refurbishment interval.

                  (vii) Engine Borescope Inspection. A full cold and hot section
         video borescope inspection in accordance with the Maintenance Program
         and a full on-wing power assurance run in accordance with the

         expense, for each Engine in the presence of a representative of Lessor
         prior to return of the Aircraft, and Lessee shall have corrected, at
         Lessee's expense, discrepancies found during such inspections that are
         determined to be outside the limits permitted by the Maintenance
         Program.

                  (viii) APU. The auxiliary power unit of the Aircraft ("APU")
         shall be in good operating condition. An on-aircraft hot section
         inspection (video borescope) and an operational check in accordance
         with the Maintenance Program shall have been performed by Lessee on the
         APU in the presence of a representative of Lessor prior to return of
         the Aircraft, and Lessee shall have repaired or replaced, at Lessee's
         expense, any watch items or unserviceable or reject conditions revealed
         by such borescope inspection.

         Upon written request of Lessor received at least 30 days prior to the
end of the Lease Term, Lessee will provide Lessor with storage facilities and
maintenance services for the Aircraft for a period not exceeding 90 days at such
location in the continental United States as selected by Lessee. Any storage
facilities provided by Lessee for the Aircraft pursuant to this Section G shall,
in all cases, be at the cost to Lessor of insurance and at Lessor's risk of
loss. In exchange for the maintenance and storage services described in this
Section G, Lessee will charge Lessor, and Lessor will pay to Lessee, Lessee's
rates customarily charged to third parties for similar maintenance and storage
services.

H.       REPLACEMENT ENGINES

         Lessee shall have the right to substitute an existing Engine with a
Replacement Engine at the time of return as long as such Replacement Engine is
of the same or better value, utility and modification level as the existing
Engine (taking into account the number of hours, cycles or calendar days, as
applicable, since the relevant engine's last major refurbishment). In the event
that a Replacement Engine meeting the value, utility and modification level
requirements of the immediately preceding sentence and not owned by Lessor shall
be delivered with the Airframe at the time of return, Lessee, at its own
expense, concurrently with such delivery, will furnish Lessor with a warranty
(as to title) bill of sale (which warranty shall except Lessor's Liens and
Permitted Liens of the type described in clause (viii) of the definition
thereof) with respect to such Replacement Engine, and Lessor will transfer to
Lessee, without recourse or warranty (except as to Lessor's Liens and Permitted
Liens of the type described in clause (viii) of the definition thereof), all
Lessor's right, title and interest in and to an Engine constituting part of the
Aircraft but not installed on the Airframe at the time of the return of the
Airframe.

I.       PAYMENT MECHANICS

         Any payments required to be made pursuant to this Annex shall be made
in U.S. dollars in immediately available funds to such bank account as is
designated by the payee.

remedies available thereunder) or (h) any of the foregoing relating to a
resignation by the Owner Trustee. The indemnities contained in this Section 7.1
extend to the Bank only in its individual capacity and shall not be construed as
indemnities of the Trust Indenture Estate or the Trust Estate (except to the
extent, if any, that the Bank has been reimbursed by the Trust Indenture Estate
or the Trust Estate for amounts covered by the indemnities contained in this
Section 7.1). The indemnities contained in this Section 7.1 shall survive the
termination of this Agreement. The payor of any indemnity under this Article

matter as to which such indemnity was paid.

                                  ARTICLE VIII

                   TRANSFER OF AN OWNER PARTICIPANT'S INTEREST

         Section 8.1. (a) Transfer of Interests. All provisions of Section 19(c)
of the Participation Agreement shall (with the same force and effect as if set
forth in full in this Section 8.1) be applicable to any assignment, conveyance
or other transfer by any Owner Participant of any of its right, title or
interest in and to the Participation Agreement, the Trust Estate, this Agreement
or any other Operative Document to which it is a party. If there is more than
one Owner Participant, no assignment, conveyance or other transfer by an Owner
Participant of any of its right, title or interest in and to this Agreement or
the Trust Estate shall be valid unless each other Owner Participant's prior
written consent (which consent may be withheld in the sole discretion of such
other Owner Participant) is given to such assignment, conveyance or other
transfer.

         Section 8.2. Actions of Owner Participants. If at any time prior to the
termination of this Agreement there is more than one Owner Participant, then,
subject to Section 11.5, during such time, if any action is required to be taken
by all Owner Participants and whenever any direction, authorization, approval,
consent, instruction or other action is permitted to be given or taken by Owner
Participant, it shall be given or taken only upon unanimous agreement of all
Owner Participants; provided, that the termination of this Agreement pursuant to
Section 11.1 may be effected upon the election of any Owner Participant.

                                   ARTICLE IX

                  SUCCESSOR OWNER TRUSTEES; CO-OWNER TRUSTEES;
                           AND SEPARATE OWNER TRUSTEES

         Section 9.1. Resignation of Owner Trustee; Appointment of Successor.
(a) Resignation or Removal. The Owner Trustee or any successor Owner Trustee may
resign at any time without cause by giving at least 60 days' prior written
notice to the Owner Participant, the Loan Trustee and the Lessee, such
resignation to be effective upon the acceptance of appointment by the successor
Owner Trustee under Section 9.1(b) hereof. In addition, the Owner Participant
may at any time remove the Owner Trustee without cause by a notice in writing
delivered to the Owner Trustee, the Loan Trustee and the Lessee, such removal to
be effective upon the acceptance of appointment by the successor Owner Trustee
under Section 9.1(b) hereof. In the case of the resignation or removal of the
Owner Trustee, the Owner Participant may appoint a successor Owner Trustee by an
instrument signed by the Owner Participant. If a successor Owner Trustee shall
not have been appointed within 30 days after such notice of resignation or
removal, the Owner Trustee, the Owner Participant, the Loan Trustee or the
Lessee 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

                                       10

AMENDED & RESTATED TRUST AGREEMENT (AA EETC 2001-1)

<PAGE>

appointment by such court. Any entity becoming a successor Owner Trustee
hereunder shall be deemed the "Owner Trustee" for all purposes hereof, and each
reference herein to the Owner Trustee shall thereafter be deemed a reference to
such entity.

         (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 Loan Trustee an instrument
accepting such appointment and assuming the obligations of Owner Trustee and the
Bank under the Operative Document to which each 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 trusts 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, duties 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 moneys 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 execute such documents as
are provided to it by such successor Owner Trustee and will take such further
actions as are requested of it by such successor Owner Trustee as are reasonably
required 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) Qualifications. Any successor Owner Trustee, however appointed,
shall be a Citizen of the United States and shall also be a bank or trust
company organized under the laws of the United States 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 or customary terms.

         (d) Merger, etc. Any corporation (or other entity) into which the Owner
Trustee or the Bank may be merged or converted or with which it may be
consolidated, or any corporation (or other entity) resulting from any merger,
conversion or consolidation to which the Owner Trustee or the Bank shall be a
party, or any corporation (or other entity) to which substantially all the
corporate trust business of the Owner Trustee or the Bank may be transferred
(including the owner trusteeship under this Agreement), shall, subject to the
terms of Section 9.1(c) hereof, be the Owner Trustee hereunder without further
act; provided, that such corporation shall in no event be the Loan Trustee.

         Section 9.2. Co-Trustees and Separate Trustees. (a) If at any time it
shall be necessary or prudent in order to conform to any law of any jurisdiction
in which all or any part of the Trust Estate is located or to make or defend any
claim or bring or defend any suit or action, or the Owner Trustee being advised
by counsel shall determine 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 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

                                       11

all of which shall be a Citizen of the United States approved by the Owner
Trustee and Owner Participant (and the Owner Trustee may appoint one or more of
its officers), either to act as co-trustee, jointly with the Owner Trustee, or
to act as separate trustee hereunder (any such co-trustee or separate trustee
being herein sometimes referred to as an "additional trustee"). In case any such
additional trustee or separate trustee shall resign or be removed, all the
assets, property, rights, powers or duties of such additional trustee or
separate trustee, as the case may be, so far as permitted by any applicable law,
shall vest in and be exercised by a new successor to such additional trustee,
appointed in the manner otherwise provided in this Agreement.

         (b) The Owner Trustee shall execute, acknowledge and deliver all such
instruments as may be required by any separate or additional trustee for more
fully confirming such title, rights or duties to such separate or additional
trustee. Upon the acceptance in writing of such appointment, such separate or
additional trustee shall be vested with such title to the Trust Estate or any
part thereof, and with such rights and duties, as shall be specified in the
instrument of appointment, jointly with the Owner Trustee (except insofar as
local law makes it necessary for such separate or additional trustee to act
alone) subject to all the terms of this Agreement. Any separate or additional
trustee may, at any time by a instrument in writing, constitute the Owner
Trustee its attorney-in-fact and agent, with full power and authority to do all
acts and things and to exercise all discretion on its behalf in its name. In
case any such separate or additional trustee shall die, become incapable of
acting, resigning or being removed, the title to the Trust Estate and all rights
and duties of such separate or additional trustee shall, so far as permitted by
law, vest in and be exercised by the Owner Trustee, without the appointment of a
successor to such separate or additional trustee.

         (c) All provisions of this Agreement which are for the benefit of the
Owner Trustee shall extend to and apply to each separate or additional trustee
appointed pursuant to the foregoing provisions of this Section 9.2.

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

                  (i) all powers, duties, obligations and rights conferred or
         imposed upon the Owner Trustee in respect of the custody, control and
         management of moneys, the Aircraft or documents authorized to be
         delivered hereunder or under the Participation Agreement shall be
         exercised solely by the Owner Trustee;

                  (ii) all other rights, powers, duties and obligations
         conferred or imposed upon the Owner Trustee shall be conferred or
         imposed upon and exercised or performed by the Owner Trustee and such
         additional trustee jointly, except to the extent that under any 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;

                  (iii) no power given to, or which it is provided hereby may be
         exercised by, any such additional trustee shall be exercised hereunder
         by such additional trustee, except jointly with, or with the consent in
         writing of, the Owner Trustee;

AMENDED & RESTATED TRUST AGREEMENT (AA EETC 2001-1)

<PAGE>

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

                  (v) the Owner Participant, at any time, by an instrument in
         writing may remove any such additional trustee; and

                  (vi) no appointment 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 Loan Trustee or the Noteholder in the Indenture
         Estate.

         (e) If at any time the Owner Participant shall deem it no longer
necessary or prudent in order to conform to any applicable law or shall be
advised by its counsel that it is no longer necessary or prudent in the interest
of the Owner Trustee or the Owner Participant to maintain the appointment of
such additional or separate trustee as provided herein, the Owner Participant
and the Owner Trustee shall execute and deliver any agreement supplemental
hereto and all other instruments and agreements necessary or proper to remove
any such additional or separate trustee.

                           SUPPLEMENTS AND AMENDMENTS
                     TO TRUST AGREEMENT AND OTHER DOCUMENTS

         Section 10.1. Supplements and Amendments and Delivery Thereof. Subject
to Section 12(d) of the Participation Agreement, this Agreement may not be
amended, supplemented or otherwise modified except by an instrument in writing
signed by the Owner Trustee and Owner Participant. Subject to Section 10.2
hereof and the applicable provisions of the Participation Agreement and
Indenture, the Owner Trustee will execute any amendment, supplement or other
modification of this Agreement or any other Operative Documents to which the
Owner Trustee is a party which it is requested to execute by Owner Participant
except that Owner Trustee shall not execute any such amendment, supplement or
other modification which, by the express provisions of any of the above
documents, requires the consent of any other party unless such consent shall
have been obtained; and provided, that, without the prior written consent of
Owner Participant, Owner Trustee shall not execute any such supplement,
amendment or modification.

         Section 10.2. Discretion as to Execution of Documents. Prior to
executing any document required to be executed by it pursuant to the terms of
Section 10.1 hereof, the Owner Trustee shall be entitled to receive an opinion
of its counsel to the effect that the execution of such document is authorized
hereunder and under the other Operative Documents. If in the reasonable opinion
of the Owner Trustee any such document materially adversely affects any right,
duty, immunity or indemnity in favor of the Owner Trustee hereunder or under any
other Operative Document to which the Owner Trustee is a party, the Owner
Trustee may in its discretion decline to execute such document unless Owner
Trustee is furnished with indemnification from Lessee or any other party upon
terms and in amounts reasonably satisfactory to Owner Trustee to protect the
Trust Estate and the Owner Trustee against any and all liabilities, costs and
expenses arising out of the execution of such documents.

         Section 10.3. Absence of Requirements as to Form. It shall not be
necessary for any written request furnished pursuant to Section 10.1 hereof to
specify the particular form of the proposed documents to be executed pursuant to
such Section 10.1, but it shall be sufficient if such request shall indicate the
substance thereof.

         Section 10.4. Distribution of Documents. Promptly after the execution
by the Owner Trustee of any document entered into pursuant to Section 10.1
hereof, the Owner Trustee shall mail, by certified mail, postage prepaid or send
by air courier, a conformed copy thereof to the Owner Participant, the Loan
Trustee and the Lessee, but the failure of the Owner Trustee to mail such
conformed copy shall not impair or affect the validity of such document.

         Section 10.5. No Request Needed as to Lease Supplement and Trust
Indenture Supplement. No written request pursuant to Section 10.1 hereof shall
be required to enable Owner Trustee to enter into, pursuant to Section 3.1
hereof and the Indenture, the Indenture Supplement.

                                   ARTICLE XI

                                  MISCELLANEOUS

         Section 11.1. Termination of Trust Agreement. This Agreement and the
trust created hereby shall terminate and be of no further force or effect upon
the earlier of (a) sale, transfer or other final disposition by the Owner
Trustee of all property constituting part of the Trust Estate and the final
distribution by the Owner Trustee of all moneys or other property or proceeds
constituting part of the Trust Estate in accordance with Article IV hereof,
provided that at such time Lessee shall have fully complied with all of the
terms of the Lease and the Participation Agreement and the Lien of the Indenture
shall have been discharged with respect to the Trust Estate or (b) 90 years
after the date of the earliest execution of this Agreement by any party hereto,
but if this Agreement and the trust created hereby shall be or become authorized
under applicable law to be valid for a period subsequent to 90 years after the
earliest execution of this Agreement by any party hereto (or, without limiting
the generality of the foregoing, if legislation shall become effective providing
for the validity of this Agreement and the trust created hereby for a period in
gross exceeding the period for which this Agreement and the trust created hereby
are hereinabove stated to extend and be valid), then this Agreement and the
trust created hereby shall not terminate under this subsection (b) but shall
extend to and continue in effect, but only if such nontermination and extension
shall then be valid under applicable law, until the day preceding such date as
the same shall, under applicable law, cease to be valid; otherwise this
Agreement and the trust created hereby shall continue in full force and effect
in accordance with the term hereof, subject to the Owner Participant's right to
revoke the trust created hereby and cause the Trust Estate (to the extent
applicable, subject to the Lien of the Indenture and the right of Lessee to
approve such revocation) to be distributed.

         Irrespective of any other provision of this Agreement, but subject to
Section 12(d) of the Participation Agreement, the Owner Participant, at its sole
option, may, at any time after the discharge of the Lien of the Indenture in
accordance with its terms, revoke the trust created hereby and vest in itself
title to the Aircraft, moneys or other property, proceeds and rights comprising
the Trust Estate upon delivery of written instructions to such effect to the
Owner Trustee. Upon receipt of such instructions and the satisfaction of all
liabilities of the Owner Participant to the Owner Trustee hereunder, the Owner
Trustee shall transfer to the Owner

Participant the Aircraft, moneys or other property, proceeds and rights
comprising the Trust Estate and the trust created hereby shall thereupon
terminate. In the event of the transfer of the Aircraft, moneys and other
property, proceeds and rights comprising the Trust Estate to the Owner
Participant, the Owner Participant will, to the extent of the Trust Estate and
to no greater extent, discharge the obligations of the Owner Trustee hereunder
and under the Operative Documents to which the Owner Trustee is a party (as such
obligations are limited in said instruments) (other than any obligations or
liabilities for which the Bank is answerable or accountable pursuant to this
Agreement or any other Operative Document to which the Owner Trustee is a party,
including without limitation, any obligation or liabilities attributable to the
Owner Trustee's gross negligence, willful misconduct or breach of any
representation, warranty, covenant or agreement in any such Operative Document).
In the event of such transfer, pursuant to this Section 11.1, the Owner
Participant will execute a written instrument or instruments in form and
substance satisfactory to the other parties thereto and their counsel,
evidencing the Owner Participant's full assumption of the aforementioned
obligations of the Owner Trustee. Nothing contained in this Section 11.1 shall
be deemed to impose on the Owner Participant any liability or obligation in the
event that the trust created hereby are terminated (whether by operation of law
or otherwise) other than expressly in accordance with the terms of this Section
11.1.

         Irrespective of any other provision of this Agreement, so long as any
Equipment Note is outstanding, the Owner Participant may not terminate or revoke
the trust created hereby without the prior written consent of the Loan Trustee.

         Section 11.2. Owner Participant Has No Legal Title to Trust Estate. The
Owner Participant shall not have legal title to any part of the Trust Estate. No
transfer, by operation of law or otherwise, of any right, title and interest of
the Owner Participant in and to the Trust Estate hereunder shall operate to
terminate this Agreement or the trusts hereunder or entitle any successors or
transferees of the Owner Participant to an accounting or to the transfer of
legal title to any part of the Trust Estate.

         Section 11.3. Assignment, Sale, etc. of Aircraft. Any assignment, sale,
transfer or other conveyance of the Aircraft or any part thereof by the Owner
Trustee made pursuant to the terms hereof or of the other Operative Documents
shall bind the Owner Participant and shall be effective to transfer or convey
all right, title and interest of the Owner Trustee and the Owner Participant in
and to the Aircraft or any part thereof. No purchaser or other grantee shall be
required to inquire as to the authorization, necessity, expediency or regularity
of such assignment, sale, transfer or conveyance or as to the application of any
sale or other proceeds with respect thereto by the Owner Trustee.

         Section 11.4. Trust Agreement for Benefit of Certain Parties Only.
Except for the terms of Section 19(c) of the Participation Agreement
incorporated in Article VIII hereof and except as otherwise provided in Articles
II, V and IX and Sections 10.1 and 10.4 hereof, nothing herein, whether
expressed or implied, shall be construed to give any person other than the Owner
Trustee and the Owner Participant any legal or equitable right, remedy or claim
under or in respect of this Agreement; but this Agreement shall be held to be
for the sole and exclusive benefit of the Owner Trustee and the Owner
Participant.

         Section 11.5. Citizenship of Owner Participant. If at any time there
shall be more than one Owner Participant, then any Owner Participant who shall
cease to be a Citizen of the United States shall have no voting or similar
rights under this Agreement and shall have no right to direct, influence or
limit the exercise of, or to prevent the direction or influence of, or place any
limitation on the exercise of, Owner Trustee's authority or to remove Owner
Trustee.

         Section 11.6. Notices. Unless otherwise expressly permitted by the
terms of this Agreement, all notices, requests, demands, authorizations,
directions, consents, waivers and other communications required or permitted to
be made, given, furnished or filed under this Agreement shall be in writing,
shall refer specifically to this Agreement and shall be personally delivered,

telecommunication transmission, sent by registered mail or certified mail,
return receipt requested, postage prepaid, or sent by overnight courier service,

forth for such party as set forth in Section 18 of the Participation Agreement,
or to such other telex, telecopy or other number or address as each party hereto
may hereafter specify by notice to the other parties hereto. Each such notice,
request, demand, authorization, direction, consent, waiver or other
communication shall be effective when received or, if made, given, furnished or
filed (a) by telecopy or other means of electronic facsimile or
telecommunication transmission, when confirmed, or (b) by registered or
certified mail, three Business Days after being deposited, properly addressed,
in the U.S. mail.

         Section 11.7. Severability. Any provision hereof which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction. If, however, any law pursuant to which such provisions are
held prohibited or unenforceable may be waived, such law is hereby waived by the
parties hereto to the full extent permitted, to the end that this Agreement
shall be deemed to be a valid and binding agreement in all respects, enforceable
in accordance with its terms.

         Section 11.8. Waivers, etc. No term or provision hereof may be changed,
waived, discharged or terminated orally, but only by an instrument in writing
entered into in compliance with the terms of Article X hereof; and any waiver of
the terms hereof shall be effective only in the specific instance and for the
specific purpose given.

         Section 11.9. Counterparts. This Agreement and any amendments, waivers,
consents or supplements hereto may be executed by the parties hereto in separate
counterparts (or upon separate signature pages bound together in one or more
counterparts), each of which when so executed and delivered shall be deemed to
be an original, but all such counterparts shall together constitute but one and
the same instrument.

         Section 11.10. Binding Effect, etc. All covenants and agreements
contained herein shall be binding upon, and inure to the benefit of, the Owner
Trustee and its successors and assigns, and the Owner Participant, its
successors and, to the extent permitted by Article VIII hereof, its assigns. Any
request, notice, direction, consent, waiver or other instrument or action by
Owner Participant shall bind its successors and assigns. Any Owner Participant
which shall cease to have any ownership interest shall thereupon cease to be a
party hereto or an Owner Participant for any reason and shall have no further
obligations hereunder.
