four (or five, under certain circumstances) series of Equipment Notes secured by

         WHEREAS, pursuant to the Participation Agreements, each Trust will

Date is the first Distribution Date, the original aggregate face amount of the
Certificates of such Trust) and (y) the Pool Balance of such Certificates as of

Aggregate LTV Collateral Amount for such Class of Certificates for the Current

Notes held in such Trust that has not been distributed to the Certificateholders

distribution of interest on the Certificates of such Trust or the reduction of

distribution of principal on such Distribution Date with respect to such senior
Class or Classes multiplied by (ii) (a) in the case of the Class A-1
Certificates or Class A-2 Certificates, a fraction the numerator of which equals
the Pool Balance for the Class A-1 Certificates or the Class A-2 Certificates,
as the case may be, and the denominator of which equals the aggregate Pool
Balance for the Class A-1 Certificates and the Class A-2 Certificates, in each
case prior to giving effect to any distribution of principal on such
Distribution Date with respect to either such Class of Certificates, and (b) in
the case of the Class B Certificates, the Class C Certificates and Class D
Certificates 1.0.

         Section 2.01 Agreement to Terms of Subordination; Payments from Monies
Received Only(a) . (a) Each Trustee hereby acknowledges and agrees to the terms
of subordination and distribution set forth in this Agreement in respect of each
Class of Certificates and agrees to enforce such provisions and cause all
payments in respect of the Equipment Notes and the Liquidity Facilities to be
applied in accordance with the terms of this Agreement. In addition, each
Trustee hereby agrees to cause the Equipment Notes purchased by the related
Trust to be registered in the name of the Subordination Agent or its nominee, as
agent and trustee for such Trustee, to be held in trust by the Subordination
Agent solely for the purpose of facilitating the enforcement of the
subordination and other provisions of this Agreement.

         (b) Except as otherwise expressly provided in the next succeeding
sentence of this Section 2.01(b), all payments to be made by the Subordination
Agent hereunder shall be made only from amounts received by it that constitute
Scheduled Payments, Special Payments and other payments under the Operative
Agreements, including payments under Section 4.02 of the Participation

the extent available for distribution to it as provided in this Agreement or the

Agreement, the Subordination Agent shall establish and maintain in its name (i)
the Collection Account as an Eligible Deposit Account, bearing a designation
clearly indicating that the funds deposited therein are held in trust for the
benefit of the Trustees, the Certificateholders and the Liquidity Providers, and
(ii) as a sub-account in the Collection Account, the Special Payments Account as
an Eligible Deposit Account, bearing a designation clearly indicating that the
funds deposited therein are held in trust for the benefit of the Trustees, the
Certificateholders and the Liquidity Providers. The Subordination Agent shall
establish and maintain the Cash Collateral Accounts pursuant to and under the
circumstances set forth in Section 3.06(f). Upon such establishment and
maintenance under Section 3.06(f), the Cash Collateral Accounts shall, together
with the Collection Account, constitute the "Trust Accounts" hereunder.

         (b) Funds on deposit in the Trust Accounts shall be invested and
reinvested by the Subordination Agent in Eligible Investments selected by
American or its designated representative if such investments are reasonably
available and have maturities no later than the earlier of (i) 90 days following

Section 2.04, as the case may be, next following the date of such investment;

Non-Extension Drawing under any Liquidity Facility, the Subordination Agent
shall invest and reinvest the amounts in the applicable Cash Collateral Account
in Eligible Investments pursuant to the written instructions of the Liquidity
Provider funding such Drawing, and provided further, however, that upon the
occurrence and during the continuation of a Triggering Event, the Subordination
Agent shall invest and reinvest such amounts (other than amounts in the Cash
Collateral Accounts as a result of a Downgrade Drawing or a Non-Extension
Drawing, which shall be governed by the foregoing proviso) in Eligible
Investments in accordance with the written instructions of the Controlling
Party. Unless otherwise expressly provided in this Agreement (including, without
limitation, with respect to Investment Earnings on amounts on deposit in the
Cash Collateral Accounts, Section 3.06(f)), any Investment Earnings shall be
deposited in the Collection Account when received by the Subordination Agent and
shall be applied by the Subordination Agent in the same manner as the other
amounts on deposit in the Collection Account are to be applied. The
Subordination Agent's reasonable fees and expenses in making such investments
and any losses incurred in such investments shall be charged against the
principal amount invested. The Subordination Agent shall not be liable for any
loss resulting from any investment, reinvestment or liquidation required to be
made under this Agreement other than by reason of its willful misconduct or
negligence. Eligible Investments and any other investment required to be made
hereunder shall be held to their maturities except that any such investment may
be sold (without regard to its maturity) by the Subordination Agent without

                                       23

instructions whenever such sale is necessary to make a distribution required
under this Agreement. Uninvested funds held hereunder shall not earn or accrue
interest.

         (c) The Subordination Agent shall possess all right, title and interest
in all funds on deposit from time to time in the Trust Accounts and in all
proceeds thereof (including all income thereon, except as otherwise expressly
provided herein with respect to Investment Earnings). The Trust Accounts shall
be held in trust by the Subordination Agent under the sole dominion and control
of the Subordination Agent for the benefit of the Trustees, the
Certificateholders and the Liquidity Providers, as the case may be. If, at any
time, any of the Trust Accounts ceases to be an Eligible Deposit Account, the
Subordination Agent shall within 10 Business Days (or such longer period, not to
exceed 30 calendar days, to which each Rating Agency may consent) establish a
new Collection Account, Special Payments Account or Cash Collateral Account, as
the case may be, as an Eligible Deposit Account and shall transfer any cash
and/or any investments to such new Collection Account, Special Payments Account
or Cash Collateral Account, as the case may be. So long as the Subordination
Agent is an Eligible Institution, the Trust Accounts shall be maintained with it
as Eligible Deposit Accounts.

Account; Certain Distributions. (a) The Subordination Agent shall, on each day
when one or more Scheduled Payments are made to the Subordination Agent as
holder of the Equipment Notes, deposit in the Collection Account the aggregate

Payments are made to the Subordination Agent as holder of the Equipment Notes,

Agent pursuant to Section 3.04 or clause "first" of Section 3.03 of any Owned
Aircraft Indenture or Section 3.04 or clause "first" of Section 3.05 of any
Leased Aircraft Indenture any amounts payable under clauses (b), (c) or (d) of
Section 2.14 of any Indenture, the Subordination Agent shall promptly deposit
such amounts in the Collection Account. The Subordination Agent will distribute
promptly upon receipt thereof (or in the case of any such payment, compensation
or reimbursement in respect of the Subordination Agent, will retain) (i) any
indemnity payment received by it from American in respect of any Trustee, the
Subordination Agent or any Liquidity Provider (collectively, the "Payees") and
(ii) any compensation or reimbursement received by it from American or the Loan
Trustee under any Operative Agreement in respect of any Payee (including,
without limitation, any fees payable to any Liquidity Provider under Section
2.03 of any Liquidity Facility or other amounts referred to in clauses (a), (e)
or (f) of Section 2.14 of any Indenture), in any such case directly to the Payee
entitled thereto, provided that if such Payee has previously received from the
Collection Account such payment, compensation or reimbursement, then the

         Section 2.06 Controlling Party. (a) The Trustees and the Liquidity
Providers hereby agree that, with respect to any Indenture at any given time,
the Loan Trustee thereunder will be directed (i) in taking, or refraining from
taking, any action under such Indenture or with respect to the Equipment Notes
issued thereunder, so long as no Indenture Event of Default has occurred and is
continuing thereunder, by the holders of at least a majority of the outstanding
principal amount of such Equipment Notes (provided that, for so long as the
Subordination Agent is the registered holder of such Equipment Notes, the
Subordination Agent shall act with respect to this clause (i) in accordance with
the directions of the Trustees of Trusts for which the related Trust Properties
include, in the aggregate, such a majority of outstanding principal amount of
such Equipment Notes), and (ii) after the occurrence and during the continuance
of an Indenture Event of Default thereunder, in taking, or refraining from
taking, any action under such Indenture or with respect to such Equipment Notes,
including exercising remedies thereunder (including Accelerating the Equipment
Notes issued thereunder or foreclosing the Lien created thereunder on the
Aircraft securing such Equipment Notes), by the Subordination Agent as directed
by the Controlling Party.

         (b) The Person who shall be the "Controlling Party" with respect to any
Indenture shall be: (v) initially, the Class A-1 Trustee or the Class A-2
Trustee, whichever represents the Class with the larger Pool Balance of
Certificates Outstanding at the time such Indenture Event of Default occurs
(whether or not any other Indenture Event of Default shall thereafter occur so
long as such initial Indenture Event of Default shall continue); (w) upon
payment of Final Distributions to the holders of Certificates of such larger
Class, the other of the Class A-1 Trustee or the Class A-2 Trustee; (x) upon
payment of Final Distributions to the holders of Class A-1 Certificates and
Class A-2 Certificates, the Class B Trustee; (y) upon payment of Final
Distributions to the holders of Class B Certificates, the Class C Trustee and
(z) upon payment of Final Distributions to the holders of Class C Certificates,
the Class D Trustee. For purposes of giving effect to the foregoing, the
Trustees (other than the Controlling Party) irrevocably agree

                                       28
<PAGE>

(and the Certificateholders (other than the Certificateholders represented by
the Controlling Party) shall be deemed to agree by virtue of their purchase of
Certificates) that the Subordination Agent, as record holder of the Equipment
Notes, shall exercise its voting rights in respect of the Equipment Notes as
directed by the Controlling Party and any vote so exercised shall be binding
upon the Trustees and all Certificateholders.

         The Subordination Agent shall give written notice to all of the other
parties to this Agreement promptly upon a change in the identity of the
Controlling Party. Each of the parties hereto agrees that it shall not exercise
any of the rights of the Controlling Party at such time as it is not the
Controlling Party hereunder; provided, however, that nothing herein contained
shall prevent or prohibit any Non-Controlling Party from exercising such rights
as shall be specifically granted to such Non-Controlling Party hereunder and
under the other Operative Agreements.

         (c) Notwithstanding the foregoing, at any time after 18 months from the
earliest to occur of (i) the date on which the entire Available Amount under any
Liquidity Facility shall have been drawn (for any reason other than a Downgrade
Drawing or a Non-Extension Drawing) and remain unreimbursed, (ii) the date on
which the entire amount of any Downgrade Drawing or Non-Extension Drawing under
any Liquidity Facility shall have become and remain "Applied Downgrade Advances"
or "Applied Non-Extension Advances", as the case may be, under and as defined in
such Liquidity Facility and (iii) the date on which all Equipment Notes shall
have been Accelerated, the Liquidity Provider(s) with the greatest amount of
unreimbursed Liquidity Obligations shall have the right to elect, by Written
Notice to the Subordination Agent and each of the Trustees, to become the
Controlling Party hereunder with respect to any Indenture at any time from and
including the last day of such 18-month period.

         (d) The exercise of remedies by the Controlling Party under this
Agreement shall be expressly limited by Section 4.01(a)(ii).

         (e) The Controlling Party shall not be entitled to require or obligate
any Non-Controlling Party to provide funds necessary to exercise any right or
remedy hereunder.

         (f) Notwithstanding anything contained herein, neither the Controlling
Party nor the Subordination Agent shall be authorized or empowered to do
anything that would cause any Trust to fail to qualify as a "grantor trust" for
federal income tax purposes.

shall be distributed to the Class E Trustee.

Subordination Agent for which no provision as to the application thereof is made
in this Agreement shall be distributed by the Subordination Agent in the order

         (c) Except as otherwise provided in Section 3.03 or Sections 3.06(a)
and 3.06(b), if the Subordination Agent receives any Scheduled Payment after the
Scheduled Payment Date relating thereto, but prior to such payment becoming an
Overdue Scheduled Payment, then the Subordination Agent shall deposit such
Scheduled Payment in the Collection Account and promptly distribute such
Scheduled Payment in accordance with the priority of distributions set forth in
Section 3.02; provided that, for the purposes of this Section 3.04(c) only, each
reference in clause "tenth" of Section 3.02 to "Distribution Date" shall be
deemed to mean the actual date of payment of such Scheduled Payment and each
reference in clause "fifth", "sixth", "seventh", "eighth" or "ninth of Section
3.02 to "Distribution Date" shall be deemed to refer to such Scheduled Payment
Date.

         Section 3.05 Payments to the Trustees and the Liquidity Providers. Any
amounts distributed hereunder to any Liquidity Provider shall be paid to such
Liquidity Provider by wire transfer of funds to the address such Liquidity
Provider shall provide to the Subordination Agent. The Subordination Agent shall
provide a Written Notice of any such transfer to the applicable Liquidity
Provider at the time of such transfer. Any amounts distributed hereunder by the
Subordination Agent to any Trustee that is not the same institution as the
Subordination Agent shall be paid to such Trustee by wire transfer of funds at
the address such Trustee shall provide to the Subordination Agent.

         Section 3.06 Liquidity Facilities. (a) Interest Drawings. If on any
Distribution Date, after giving effect to the subordination provisions of this
Agreement, the Subordination Agent shall not have sufficient funds for the
payment of any amounts due and owing in respect of accrued interest on the Class
A-1 Certificates, the Class A-2 Certificates, the Class B Certificates or the
Class C Certificates (at the Stated Interest Rate for such Class of
Certificates), then, prior to 1:00 p.m.(New York City time) on such Distribution
Date, the Subordination Agent shall request a drawing (each such drawing, an
"Interest Drawing") under the Liquidity Facility with respect to such Class of
Certificates in an amount equal to the lesser of (i) an amount sufficient to pay
the amount of such accrued interest (at the Stated Interest Rate for each such
Class of Certificates) and (ii) the Available Amount under such Liquidity
Facility, and shall upon receipt of such amount pay such amount to the Trustee
with respect to each such Class of Certificates in payment of such accrued
interest as provided in Section 3.06(b).

         (b) Application of Interest Drawings. Notwithstanding anything to the
contrary contained in this Agreement, (i) all payments received by the
Subordination Agent in respect of an Interest Drawing under the Class A-1
Liquidity Facility and all amounts withdrawn by the Subordination Agent from the
Class A-1 Cash Collateral Account, and payable in each case to the Class A-1
Certificateholders, shall be promptly distributed to the Class A-1 Trustee, (ii)
all payments received by the Subordination Agent in respect of an Interest

each case to the Class A-2 Certificateholders, shall be promptly distributed to
the Class A-2 Trustee, (iii) all payments received by the Subordination Agent in
respect of an Interest Drawing under the Class B Liquidity Facility and all
amounts withdrawn by the Subordination Agent from the Class B Cash Collateral
Account, and payable

                                       37
<PAGE>

in each case to the Class B Certificateholders, shall be promptly distributed to
the Class B Trustee, and (iv) all payments received by the Subordination Agent
in respect of an Interest Drawing under the Class C Liquidity Facility and all
amounts withdrawn by the Subordination Agent from the Class C Cash Collateral
Account, and payable in each case to the Class C Certificateholders, shall be
promptly distributed to the Class C Trustee.

         (c) Downgrade Drawings. The Liquidity Provider will promptly, but in
any event within ten days of its receipt of notice thereof, deliver notice of
any downgrading of its debt ratings to the Subordination Agent and American. If
at any time the short-term unsecured debt rating of any Liquidity Provider
issued by either Rating Agency (or, if such Liquidity Provider does not have a
short-term unsecured debt rating issued by a given Rating Agency, the long-term
unsecured debt rating of such Liquidity Provider issued by such Rating Agency)
is lower than the applicable Threshold Rating, within 10 days after such
Liquidity Provider receives notice of such downgrading (or within 45 days after
its receipt of such notice solely in the event of a downgrading of such
Liquidity Provider's short-term unsecured debt rating by S&P from A-1+ to A-1)
(but not later than the expiration date of the Liquidity Facility issued by the
downgraded Liquidity Provider (the "Downgraded Facility")), such Liquidity
Provider or American may arrange for a Replacement Liquidity Provider to issue
and deliver a Replacement Liquidity Facility to the Subordination Agent. If a
Downgraded Facility has not been replaced in accordance with the terms of this
paragraph, the Subordination Agent shall, on such 10th (or 45th) day (or if such
10th (or 45th) day is not a Business Day, on the next succeeding Business Day)
(or, if earlier, on the expiration date of such Downgraded Facility), request a
drawing in accordance with and to the extent permitted by such Downgraded
Facility (such drawing, a "Downgrade Drawing") of all available and undrawn
amounts thereunder. Amounts drawn pursuant to a Downgrade Drawing shall be
maintained and invested as provided in Section 3.06(f). Subject to Section
3.06(e)(iii), the Liquidity Provider may also arrange for a Replacement
Liquidity Provider to issue and deliver a Replacement Liquidity Facility at any
time after such Downgrade Drawing so long as such Downgrade Drawing has not been
reimbursed in full to the Liquidity Provider.

         (d) Non-Extension Drawings. If any Liquidity Facility with respect to
any Class of Certificates is scheduled to expire on a date (the "Stated
Expiration Date") prior to the date that is 15 days after the Final Legal
Distribution Date for such Class of Certificates, then no earlier than the 60th
day and no later than the 40th day prior to the then applicable Stated
Expiration Date, the Subordination Agent shall request in writing that such
Liquidity Provider extend the Stated Expiration Date to the earlier of (i) the
date that is 15 days after the Final Legal Distribution Date for such Class of
Certificates and (ii) the date that is the day immediately preceding the 364th
day after the last day of the Consent Period (unless the obligations of such
Liquidity Provider thereunder are earlier terminated in accordance with such
Liquidity Facility). Whether or not the applicable Liquidity Provider has
received such a request from the Subordination Agent, the Liquidity Provider
shall by notice (the "Consent Notice") to the Subordination Agent during the
period commencing on the date that is 60 days prior to the then effective Stated
Expiration Date and ending on the date that is 25 days prior to such Stated
Expiration Date (the "Consent Period") advise the Subordination Agent whether,
in its sole

                                       38
<PAGE>

discretion, it agrees to so extend the Stated Expiration Date; provided,
however, that such extension shall not be effective with respect to such
Liquidity Provider if, by notice (the "Withdrawal Notice") to the Subordination
Agent prior to the end of the Consent Period, the Liquidity Provider revokes its
Consent Notice; provided, further, Boeing Capital Corporation shall not agree to
extend the Stated Expiration Date beyond November 24, 2001 unless it shall have
received the written consent of Moody's. If the Liquidity Provider advises the
Subordination Agent in the Consent Notice that such Stated Expiration Date shall
not be so extended or gives a Withdrawal Notice to the Subordination Agent prior
to the end of the Consent Period, or fails to irrevocably and unconditionally
advise the Subordination Agent on or before the end of the Consent Period that
such Stated Expiration Date shall be so extended (and, in each case, if the
Liquidity Provider shall not have been replaced in accordance with Section
3.06(e)), the Subordination Agent shall, on the date on which the Consent Period
ends (or as soon as possible thereafter but prior to the Stated Expiration
Date), in accordance with and to the extent permitted by the terms of the
expiring Liquidity Facility (a "Non-Extended Facility"), request a drawing under
such expiring Liquidity Facility (such drawing, a "Non-Extension Drawing") of
all available and undrawn amounts thereunder. Amounts drawn pursuant to a
Non-Extension Drawing shall be maintained and invested in accordance with
Section 3.06(f). If any amounts shall be drawn pursuant to a Non-Extension
Drawing and, within 30 days thereafter, the Liquidity Provider shall not have
been replaced, then at any time following the 30th day after such Non-Extension
Drawing, the Liquidity Provider may, by written notice to the Subordination
Agent, agree to reinstate the Liquidity Facility on the terms of the existing
Liquidity Facility for a period ending on the 364th day after the end of the
Consent Period; provided, however, that in such event the Liquidity Provider
shall reimburse the Subordination Agent for any costs actually incurred by or on
behalf of the Subordination Agent in drawing pursuant to the Non-Extension
Drawing and funding the Cash Collateral Account or otherwise in connection with
the Non-Extension Drawing.

         (e) Issuance of Replacement Liquidity Facility. (i) Subject to Section
3.06(e)(iii), at any time, American may, at its option, with cause or without
cause, arrange for a Replacement Liquidity Facility to replace any Liquidity
Facility for any Class of Certificates (including any Replacement Liquidity
Facility provided pursuant to Section 3.06(e)(ii)); provided, however, that if
the initial Liquidity Provider is replaced it shall be replaced with respect to
all Liquidity Facilities under which it is a Liquidity Provider, and provided
further, however, that the initial Liquidity Provider shall not be replaced by
American as the Liquidity Provider with respect to any Class of Certificates
prior to the fifth anniversary of the Closing Date unless (A) there shall have
become due to the initial Liquidity Provider, or the initial Liquidity Provider
shall have demanded, amounts pursuant to Section 3.01 or 3.03 of any Liquidity
Facility and the replacement of the initial Liquidity Provider would reduce or
eliminate the obligation to pay such amounts or American determines in good
faith that there is a substantial likelihood that the initial Liquidity Provider
will have the right to claim any such amounts within 180 days after the date of
such determination (unless the initial Liquidity Provider waives, in writing,
any right it may have to claim such amounts), which determination shall be set
forth in a certificate delivered by American to the initial Liquidity Provider
accompanied by an opinion of outside counsel selected by American and reasonably
acceptable to such initial Liquidity Provider verifying the legal

                                       39
<PAGE>

conclusions, if any, of such certificate relating to such basis, provided that
in the case of any likely claim for amounts based upon any proposed, or proposed
change in, law, rule, regulation, interpretation, directive, requirement,
request or administrative practice, such opinion may assume the adoption or
promulgation of such proposed matter, (B) it shall become unlawful or impossible
for the initial Liquidity Provider to maintain or fund its LIBOR Advances as
described in Section 3.10 of any Liquidity Facility, (C) the short-term
unsecured debt rating of the initial Liquidity Provider is downgraded by S&P
from A-1+ to A-1 and there is a resulting downgrade in the rating by either
Rating Agency of any Class of Certificates, (D) any Liquidity Facility of such
initial Liquidity Provider shall become a Downgraded Facility or a Non-Extended
Facility or a Downgrade Drawing or a Non-Extension Drawing shall have occurred
under any Liquidity Facility or (E) the initial Liquidity Provider shall have
breached any of its payment (including, without limitation, funding) obligations
under any Liquidity Facility. If such Replacement Liquidity Facility is provided
at any time after a Downgrade Drawing or a Non-Extension Drawing has been made,
all funds on deposit in the relevant Cash Collateral Account resulting from such
Downgrade Drawing or Non-Extension Drawing will be returned to the Liquidity
Provider being replaced.

         (ii) If any Liquidity Provider shall determine not to extend its
Liquidity Facility in accordance with Section 3.06(d), then such Liquidity
Provider may, at its option, arrange for a Replacement Liquidity Facility to
replace such Liquidity Facility during the period no earlier than 40 days and no
later than 25 days prior to the then effective Stated Expiration Date of such
Liquidity Facility. Subject to Section 3.06(e)(iii), the Liquidity Provider may
also arrange for a Replacement Liquidity Provider to issue and deliver a
Replacement Liquidity Facility at any time after such Non-Extension Drawing so
long as such Non-Extension Drawing has not been reimbursed in full to the
Liquidity Provider.

         (iii) No Replacement Liquidity Facility arranged by American or a
Liquidity Provider in accordance with Section 3.06(c) or clause (i) or (ii) of
this Section 3.06(e) shall become effective and no such Replacement Liquidity
Facility shall be deemed a "Liquidity Facility" under the Operative Agreements,
unless and until (A) each of the conditions referred to in Section 3.06(e)(iv)
below shall have been satisfied and (B) in the case of a Replacement Liquidity
Facility arranged by a Liquidity Provider under Section 3.06(c) or Section
3.06(e)(ii), such Replacement Liquidity Provider and such Replacement Liquidity
Facility (including the fees and compensation and interest payable thereunder to
the Replacement Liquidity Provider) are acceptable to American.

         (iv) In connection with the issuance of each Replacement Liquidity
Facility, the Subordination Agent shall (x) prior to the issuance of such
Replacement Liquidity Facility, obtain written confirmation from each Rating
Agency that such Replacement Liquidity Facility will not cause a reduction of
any rating then in effect for any Class of Certificates by such Rating Agency
(without regard to any downgrading of any rating of any Liquidity Provider being
replaced pursuant to Section 3.06(c)), (y) pay all Liquidity Obligations then
owing to the replaced Liquidity Provider (which payment shall be made first from
available funds in the applicable Cash Collateral Account as described in
Section 3.06(f)(ix), and thereafter from any

                                       40
<PAGE>

other available source, including, without limitation, a drawing under the
Replacement Liquidity Facility) and (z) cause the issuer of the Replacement
Liquidity Facility to deliver the Replacement Liquidity Facility to the
Subordination Agent, together with a legal opinion addressed to the
Subordination Agent, the Trustees and American opining that such Replacement
Liquidity Facility is an enforceable obligation of such Replacement Liquidity
Provider.

         (v) Upon satisfaction of the conditions set forth in Sections
3.06(e)(iii) and 3.06(e)(iv), (w) the replaced Liquidity Facility shall
terminate, (x) the Subordination Agent shall, if and to the extent so requested
by American or the Liquidity Provider being replaced, execute and deliver any
certificate or other instrument required in order to terminate the replaced
Liquidity Facility, shall surrender the replaced Liquidity Facility to the
Liquidity Provider being replaced and shall execute and deliver the Replacement
Liquidity Facility and any associated Fee Letter, (y) each of the parties hereto
shall enter into any amendments to this Agreement necessary to give effect to
(1) the replacement of the applicable Liquidity Provider with the applicable
Replacement Liquidity Provider and (2) the replacement of the applicable
Liquidity Facility with the applicable Replacement Liquidity Facility and (z)
the applicable Replacement Liquidity Provider shall be deemed to be a Liquidity
Provider with the rights and obligations of a Liquidity Provider hereunder and
under the other Operative Agreements and such Replacement Liquidity Facility
shall be deemed to be a Liquidity Facility hereunder and under the other
Operative Agreements.

         (f) Cash Collateral Accounts; Withdrawals; Investments. If the
Subordination Agent shall draw all available amounts under the Class A-1
Liquidity Facility, the Class A-2 Liquidity Facility, the Class B Liquidity
Facility or the Class C Liquidity Facility pursuant to Section 3.06(c), 3.06(d)
or 3.06(i), or in the event amounts are to be deposited in the Cash Collateral
Account pursuant to subclause (A) or (B) of clause "third" of Section 2.04(b),
subclause (A) or (B) of clause "third" of Section 3.02 or subclause (A) or (B)
of clause "fourth" of Section 3.03, amounts so drawn or to be deposited, as the
case may be, shall be deposited by the Subordination Agent in the Class A-1 Cash
Collateral Account, the Class A-2 Cash Collateral Account, the Class B Cash
Collateral Account or the Class C Cash Collateral Account, respectively. All
amounts on deposit in each Cash Collateral Account shall be invested and
reinvested in Eligible Investments in accordance with Section 2.02(b). On each
Interest Payment Date (or, in the case of any Special Distribution Date
occurring prior to the occurrence of a Triggering Event, on such Special
Distribution Date), Investment Earnings on amounts on deposit in each Cash
Collateral Account (or in the case of any Special Distribution Date occurring
prior to the occurrence of a Triggering Event, an amount of such Investment
Earnings on amounts of deposits in each Cash Collateral Account equal to the
product of such Investment Earnings multiplied by a fraction, the numerator of
which is the aggregate outstanding principal amount of Equipment Notes being
redeemed, purchased or prepaid on such Special Distribution Date and the
denominator of which is the aggregate outstanding principal amount of all
Equipment Notes) shall be deposited in the Collection Account (or, in the case
of any Special Distribution Date occurring prior to the occurrence of a
Triggering Event, the Special Payments Account) and applied on such Interest
Payment Date (or Special Distribution Date, as the case may be) in accordance
with Section 2.04(b), 3.02, 3.03 or 3.04(b) (as applicable). The Subordination
Agent shall deliver a written

                                       41
<PAGE>

statement to American and the Liquidity Provider one day prior to each Interest
Payment Date and Special Distribution Date setting forth the aggregate amount of
Investment Earnings held in the Cash Collateral Accounts as of such date. In
addition, from and after the date funds are so deposited, the Subordination
Agent shall make withdrawals from such account as follows:

         (i) on each Distribution Date, the Subordination Agent shall, to the
extent it shall not have received funds to pay accrued and unpaid interest due
and owing on the Class A-1 Certificates (at the Stated Interest Rate for the

such reduction resulting from a prior withdrawal of amounts on deposit in the
Class A-1 Cash Collateral Account on such date) and any transfer of Investment
Earnings from such Class A-1 Cash Collateral Account to the Collection Account
or the Special Payments Account on such date, an amount equal to the sum of the
Required Amount (with respect to the

                                       42

pursuant to Section 2.04(b), 3.02 or 3.03, the Subordination Agent shall
withdraw from the Class C Cash Collateral Account such amount as is necessary so
that, after giving effect to the reduction of such Pool Balance on such date
(including any such reduction resulting from a prior withdrawal of amounts on
deposit in the Class C Cash Collateral Account on such date) and any transfer of

particular Liquidity Facility, (i) funds are withdrawn from any Cash Collateral
Account pursuant to clause (i), (ii), (iii) or (iv) of Section 3.06(f) or (ii)
such Liquidity Facility shall become a Downgraded Facility or a Non-Extended
Facility at a time when unreimbursed Interest Drawings under such Liquidity
Facility have reduced the Available Amount thereunder to zero, then funds
received by the Subordination Agent at any time, other than (x) any time when
both a Performing Note Deficiency exists and a Liquidity Event of Default shall
have occurred and be continuing with respect to such Liquidity Facility or (y)
any time after a Final Drawing shall have occurred with respect to such

Termination Notice with respect to any Liquidity Facility, the Subordination
Agent shall, not later than the date specified in such Termination Notice, in
accordance with and to the extent permitted by the terms of such Liquidity
Facility, request a drawing under such Liquidity Facility of all available and
undrawn amounts thereunder (a "Final Drawing"). Amounts drawn pursuant to a
Final Drawing shall be maintained and invested in accordance with Section

         (j) Reduction of Stated Amount. Promptly following each date on which
the Required Amount of the Liquidity Facility for a Class of Certificates is
reduced as a result of a reduction in the Pool Balance with respect to such
Certificates, the Subordination Agent shall, if any such Liquidity Facility
provides for reductions of the Stated Amount of such Liquidity Facility and if
such reductions are not automatic, request such Liquidity Provider for such
Class of Certificates to reduce such Stated Amount to an amount equal to the
Required Amount with respect to such Liquidity Facility (as calculated by the
Subordination Agent after giving effect to such payment). Each such request
shall be made in accordance with the provisions of the applicable Liquidity
Facility.

         (k) Relation to Subordination Provisions. Interest Drawings under the
Liquidity Facilities and withdrawals from the Cash Collateral Accounts, in each
case, in respect of interest on the Certificates of any Class, will be
distributed to the Trustee for such Class of Certificates, notwithstanding
Sections 2.04(b), 3.02, 3.03 and 3.06.

         (l) Assignment of Liquidity Facility. The Subordination Agent agrees
not to consent to the assignment by any Liquidity Provider of any of its rights
or obligations under any Liquidity Facility or any interest therein unless (i)
American shall have consented to such assignment and (ii) each Rating Agency
shall have provided a Ratings Confirmation in respect of such assignment.

                                   ARTICLE IV

                              EXERCISE OF REMEDIES

         Section 4.01 Directions from the Controlling Party. (a) (i) Following
the occurrence and during the continuation of an Indenture Event of Default
under any Indenture, the Controlling Party shall direct the Subordination Agent,
which in turn shall direct the Loan Trustee under such Indenture, in the
exercise of remedies available to the holders of the Equipment Notes issued
pursuant to such Indenture, including, without limitation, the ability to vote
all such Equipment Notes in favor of Accelerating such Equipment Notes in
accordance with the provisions of such Indenture. If the Equipment Notes issued
pursuant to any Indenture

                                       45
<PAGE>

have been Accelerated following an Indenture Event of Default with respect
thereto, the Controlling Party may direct the Subordination Agent to sell,
assign, contract to sell or otherwise dispose of and deliver all (but not less
than all) of such Equipment Notes to any Person at public or private sale, at
any location at the option of the Controlling Party, all upon such terms and
conditions as it may reasonably deem advisable and in accordance with applicable
law.

         (ii) Subject to the Owner Trustees' and the Owner Participants' rights
set forth in the Indentures with respect to Leased Aircraft to purchase the
Equipment Notes, so long as any Certificates remain Outstanding, during the
period ending on the date which is nine months after the earlier of (x) the
Acceleration of the Equipment Notes issued pursuant to any Indenture or (y) the
occurrence of an American Bankruptcy Event, without the consent of each Trustee,
(A) no Aircraft subject to the Lien of such Indenture or such Equipment Notes
may be sold if the net proceeds from such sale would be less than the Minimum
Sale Price for such Aircraft or such Equipment Notes and (B) with respect to any
Leased Aircraft, the amount and payment dates of rentals payable by American
under the Lease for such Aircraft may not be adjusted, if, as a result of such
adjustment, the discounted present value of all such rentals would be less than
75% of the discounted present value of the rentals payable by American under
such Lease before giving effect to such adjustment, in each case, using the
weighted average interest rate of the Equipment Notes issued pursuant to such
Indenture as the discount rate.

         (iii) At the request of the Controlling Party, the Subordination Agent
may from time to time during the continuance of an Indenture Event of Default
(and before the occurrence of a Triggering Event) commission an appraisal with
respect to the Aircraft subject to such Indenture.

         (iv) After a Triggering Event occurs and any Equipment Note becomes a
Non-Performing Equipment Note, the Subordination Agent shall obtain Appraisals
with respect to all of the Aircraft (the "LTV Appraisals") as soon as
practicable and additional LTV Appraisals on or prior to each anniversary of the
date of such initial LTV Appraisals; provided that, if the Controlling Party
reasonably objects to the appraised value of the Aircraft shown in such LTV
Appraisals, the Controlling Party shall have the right to obtain or cause to be
obtained substitute LTV Appraisals (including any LTV Appraisals based upon
physical inspection of the Aircraft).

         (b) To the extent permitted by applicable law, the Subordination Agent,
at the direction of the Controlling Party, shall take such actions as it may
reasonably deem most effectual to complete the sale or other disposition of such
Aircraft or Equipment Notes. In addition, in lieu of any sale, assignment,
contract to sell or other disposition, if the Subordination Agent is so directed
by the Controlling Party, the Subordination Agent may maintain possession of
such Equipment Notes and continue to apply monies received in respect of such
Equipment Notes in accordance with Section 2.04(b) and Article III. In addition,
in lieu of such sale, assignment, contract to sell or other disposition, or in
lieu of such maintenance of possession, the Controlling Party may direct the
Subordination Agent to, subject to the terms and conditions of the related
Indenture, instruct the Loan Trustee under such Indenture to foreclose on the
Lien on

                                       46
<PAGE>

the related Aircraft or take any other remedial action permitted by such
Indenture or applicable law.

         Section 4.02 Remedies Cumulative. Each and every right, power and
remedy given to the Trustees, the Liquidity Providers, the Controlling Party or
the Subordination Agent specifically or otherwise in this Agreement shall be
cumulative and shall be in addition to every other right, power and remedy
herein specifically given or now or hereafter existing at law, in equity or by
statute, and each and every right, power and remedy whether specifically herein
given or otherwise existing may, subject always to the terms and conditions
hereof, be exercised from time to time and as often and in such order as may be
deemed expedient by any Trustee, any Liquidity Provider, the Controlling Party
or the Subordination Agent, as appropriate, and the exercise or the beginning of
the exercise of any right, power or remedy shall not be construed to be a waiver
of the right to exercise at the same time or thereafter any other right, power
or remedy. No delay or omission by any Trustee, any Liquidity Provider, the
Controlling Party or the Subordination Agent in the exercise of any right,
remedy or power or in the pursuit of any remedy shall impair any such right,
power or remedy or be construed to be a waiver of any default or to be an
acquiescence therein.

         Section 4.03 Discontinuance of Proceedings. In case any party to this
Agreement (including the Controlling Party in such capacity) shall have
instituted any Proceeding to enforce any right, power or remedy under this
Agreement by foreclosure, entry or otherwise, and such Proceeding shall have
been discontinued or abandoned for any reason or shall have been determined
adversely to the Person instituting such Proceeding, then and in every such case
each such party shall, subject to any determination in such Proceeding, be
restored to its former position and rights hereunder, and all rights, remedies
and powers of such party shall continue as if no such Proceeding had been
instituted.

         Section 4.04 Right of Certificateholders to Receive Payments Not to Be
Impaired. Subject to the provisions of this Agreement and each Trust Agreement,
the right of any Certificateholder or any Liquidity Provider, respectively, to
receive payments hereunder (including, without limitation, pursuant to Section
2.04, 3.02 or 3.03) when due, or to institute suit for the enforcement of any
such payment on or after the applicable Distribution Date, shall not be impaired
or affected without the consent of such Certificateholder or such Liquidity
Provider, respectively.

                       DUTIES OF THE SUBORDINATION AGENT;

         Section 5.01 Notice of Indenture Event of Default or Triggering Event.
(a) If the Subordination Agent shall have knowledge of an Indenture Event of
Default or a Triggering Event, the Subordination Agent shall promptly give
notice thereof to the Rating Agencies,

                                       47
<PAGE>

American, the Liquidity Providers and the Trustees by telegram, cable, facsimile
or telephone (to be promptly confirmed in writing), unless such Indenture Event
of Default or Triggering Event shall have been cured or waived. For all purposes
of this Agreement, in the absence of actual knowledge, the Subordination Agent
shall not be deemed to have knowledge of any Indenture Event of Default or
Triggering Event unless notified in writing by American, one or more Trustees,
one or more Liquidity Providers or one or more Certificateholders; and "actual
knowledge" (as used in the foregoing clause) of the Subordination Agent shall
mean actual knowledge of an officer in the Corporate Trust Office of the
Subordination Agent.

         (b) Other Notices. The Subordination Agent will furnish to each
Liquidity Provider and Trustee, promptly upon receipt thereof, duplicates or
copies of all reports, notices, requests, demands, certificates, financial
statements and other instruments furnished to the Subordination Agent as
registered holder of the Equipment Notes or otherwise in its capacity as
Subordination Agent to the extent the same shall not have been otherwise
directly distributed to such Liquidity Provider or Trustee, as applicable,
pursuant to any other Operative Agreement.

         Section 5.02 Indemnification. The Subordination Agent shall not be
required to take any action or refrain from taking any action under Article IV
unless the Subordination Agent shall have received indemnification against any
risks incurred in connection therewith in form and substance reasonably
satisfactory to it, including, without limitation, adequate advances against
costs that may be incurred by it in connection therewith. The Subordination
Agent shall not be required to take any action under Article IV, nor shall any
other provision of this Agreement or any other Operative Agreement be deemed to
impose a duty on the Subordination Agent to take any action, if the
Subordination Agent shall have been advised by outside counsel that such action
is contrary to the terms hereof or is otherwise contrary to law.

         Section 5.03 No Duties Except as Specified in Intercreditor Agreement.
The Subordination Agent shall not have any duty or obligation to take or refrain
from taking any action under, or in connection with, this Agreement, except as
expressly provided by the terms of this Agreement; and no implied duties or
obligations shall be read into this Agreement against the Subordination Agent.
The Subordination Agent agrees that it will, in its individual capacity and at
its own cost and expense (but without any right of indemnity in respect of any
such cost or expense) promptly take such action as may be necessary duly to
discharge all Liens on any of the Trust Accounts or any monies deposited therein
that are attributable to the Subordination Agent in its individual capacity and
that are unrelated to the transaction contemplated hereby and by the other
Operative Agreements.

         Section 5.04 Notice from the Liquidity Providers and Trustees. If any
Liquidity Provider or Trustee has notice of an Indenture Event of Default or a
Triggering Event, such Person shall promptly give notice thereof to all other
Liquidity Providers and Trustees and to the Subordination Agent; provided,
however, that no such Person shall have any liability hereunder as a result of
its failure to deliver any such notice.

                             THE SUBORDINATION AGENT

         Section 6.01 Authorization; Acceptance of Trusts and Duties. Each of
the Class A-1 Trustee, the Class A-2 Trustee, the Class B Trustee and the Class
C Trustee hereby designates and appoints the Subordination Agent as the agent
and trustee of such Trustee under the applicable Liquidity Facility and
authorizes the Subordination Agent to enter into the applicable Liquidity
Facility as agent and trustee for such Trustee. Each of the Liquidity Providers
and the Trustees hereby designates and appoints the Subordination Agent as the
Subordination Agent under this Agreement. State Street accepts the trusts and
duties hereby created and applicable to it and agrees to perform such duties,
but only upon the terms of this Agreement and agrees to receive, handle and
disburse all monies received by it in accordance with the terms hereof. The
Subordination Agent shall have no liability hereunder except (a) for its own
willful misconduct or negligence, (b) as provided in Section 2.02 and the last
sentence of Section 5.03, (c) for liabilities that may result from the
inaccuracy of any representation or warranty of the Subordination Agent made in
its individual capacity in any Operative Agreement and (d) as otherwise
expressly provided herein or in the other Operative Agreements.

         Section 6.02 Absence of Duties. The Subordination Agent shall have no
duty to see to any recording or filing of this Agreement or any other document,
or to see to the maintenance of any such recording or filing.

         Section 6.03 No Representations or Warranties as to Documents. The
Subordination Agent shall not be deemed to have made any representation or
warranty as to the validity, legality or enforceability of this Agreement or any
other Operative Agreement or as to the correctness of any statement contained
herein or therein (other than the representations and warranties of the
Subordination Agent made in its individual capacity under any Operative
Agreement), except that the Subordination Agent hereby represents and warrants
that each of said specified documents to which it is a party has been or will be
duly executed and delivered by one of its officers who is and will be duly
authorized to execute and deliver such document on its behalf. The
Certificateholders, the Trustees and the Liquidity Providers make no
representation or warranty hereunder whatsoever.

         Section 6.04 No Segregation of Monies; No Interest. Any monies paid to
or retained by the Subordination Agent pursuant to any provision hereof and not
then required to be distributed to any Trustee or any Liquidity Provider as
provided in Articles II and III or deposited into one or more Trust Accounts
need not be segregated in any manner except to the extent required by such
Articles II and III and by law, and the Subordination Agent shall not (except as
otherwise provided in Section 2.02) be liable for any interest thereon;
provided, however, that any payments received or applied hereunder by the
Subordination Agent shall be accounted for by the Subordination Agent so that
any portion thereof paid or applied pursuant hereto shall be identifiable as to
the source thereof.

                                       49
<PAGE>

         Section 6.05 Reliance; Agents; Advice of Counsel. The Subordination
Agent shall not incur any liability to anyone in acting upon any signature,
instrument, notice, resolution, request, consent, order, certificate, report,
opinion, bond or other document or paper believed by it to be genuine and
believed by it to be signed by the proper party or parties. As to the Pool
Balance of any Trust as of any date, the Subordination Agent may for all
purposes hereof rely on a certificate signed by any Responsible Officer of the
applicable Trustee, and such certificate shall constitute full protection to the
Subordination Agent for any action taken or omitted to be taken by it in good
faith in reliance thereon. As to any fact or matter relating to the Liquidity
Providers or the Trustees the manner of ascertainment of which is not
specifically described herein, the Subordination Agent may for all purposes
hereof rely on a certificate, signed by any Responsible Officer of the
applicable Liquidity Provider or Trustee, as the case may be, as to such fact or
matter, and such certificate shall constitute full protection to the
Subordination Agent for any action taken or omitted to be taken by it in good
faith in reliance thereon. In the administration of the trusts hereunder, the
Subordination Agent may (a) execute any of the trusts or powers hereof and
perform its powers and duties hereunder directly or through agents or attorneys
and (b) consult with counsel, accountants and other skilled Persons to be
selected and retained by it. The Subordination Agent shall not be liable for
anything done, suffered or omitted in good faith by it in accordance with the
advice or opinion of any such counsel, accountants or other skilled Persons
acting within such counsel's, accountants' or Person's area of competence (so
long as the Subordination Agent shall have exercised reasonable care and
judgment in selecting such Persons).

         Section 6.06 Capacity in Which Acting. The Subordination Agent acts
hereunder solely as agent and trustee herein and not in its individual capacity,
except as otherwise expressly provided in the Operative Agreements.

         Section 6.07 Compensation. The Subordination Agent shall be entitled to
such compensation, including reasonable expenses and disbursements, for all
services rendered hereunder as American and the Subordination Agent may agree
from time to time in writing and shall have a priority claim to the extent set
forth in Article III on all monies collected hereunder for the payment of such
compensation, to the extent that such compensation shall not be paid by others.
The Subordination Agent agrees that it shall have no right against any Trustee
or Liquidity Provider for any fee as compensation for its services as agent
under this Agreement. The provisions of this Section 6.07 shall survive the
termination of this Agreement.

         Section 6.08 May Become Certificateholder. The institution acting as
Subordination Agent hereunder may become a Certificateholder and have all rights
and benefits of a Certificateholder to the same extent as if it were not the
institution acting as the Subordination Agent.

         Section 6.09 Subordination Agent Required; Eligibility. There shall at
all times be a Subordination Agent hereunder that is a Citizen of the United
States, a bank, trust company or other financial institution organized and doing
business under the laws of the United States or any state thereof and eligible
to act as a trustee under Section 310(a) of the Trust Indenture Act

                                       50

of 1939, as amended, and that has a combined capital and surplus of at least
$75,000,000 (or a combined capital and surplus in excess of $5,000,000 and the
obligations of which, whether now in existence or hereafter incurred, are fully
and unconditionally guaranteed by a corporation organized under the laws of the
United States or any State or territory thereof or the District of Columbia and
having a combined capital and surplus of at least $75,000,000). If such bank,
trust company or other financial institution or such corporation publishes
reports of conditions at least annually, pursuant to law or to the requirements
of federal, state, territorial or District of Columbia supervising or examining
authority, then for the purposes of this Section 6.09 the combined capital and
surplus of such bank, trust company or other financial institution or such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of conditions so published.

         In case at any time the Subordination Agent shall cease to be eligible
in accordance with the provisions of this Section 6.09, the Subordination Agent
shall resign immediately in the manner and with the effect specified in Section
7.01.

         Section 6.10 Money to Be Held in Trust. All Equipment Notes, monies and
other property deposited with or held by the Subordination Agent pursuant to
this Agreement shall be held in trust for the benefit of the parties entitled to
such Equipment Notes, monies and other property.

                          SUCCESSOR SUBORDINATION AGENT

         Section 7.01 Replacement of Subordination Agent; Appointment of
Successor. (a) The Subordination Agent or any successor thereto must resign if
at any time it fails to comply with Section 6.09 and may resign at any time
without cause by giving 60 days' prior written notice to American, the Trustees
and the Liquidity Providers. The Controlling Party (or the party that would be
the Controlling Party if an Indenture Event of Default had occurred) shall
remove the Subordination Agent if:

         (1) the Subordination Agent fails to comply with Section 6.09;

         (2) the Subordination Agent is adjudged bankrupt or insolvent;

         (3) a receiver of the Subordination Agent shall be appointed or any
public officer shall take charge or control of the Subordination Agent or its
property or affairs for the purpose of rehabilitation, conservation or
liquidation; or

         (4) the Subordination Agent otherwise becomes incapable of acting.

                                       51
<PAGE>

         If the Subordination Agent resigns or is removed or if a vacancy exists
in the office of Subordination Agent for any reason (the Subordination Agent in
such event being referred to herein as the retiring Subordination Agent), the
Controlling Party (or the party that would be the Controlling Party if an
Indenture Event of Default had occurred) shall in consultation with American
promptly appoint a successor Subordination Agent. If a successor Subordination
Agent shall not have been appointed within 60 days after such notice of
resignation or removal, the retiring Subordination Agent, one or more of the
Trustees or one or more of the Liquidity Providers may petition any court of
competent jurisdiction for the appointment of a successor Subordination Agent to
act until such time, if any, as a successor shall have been appointed as
provided above.

         A successor Subordination Agent shall deliver (x) a written acceptance
of its appointment as Subordination Agent hereunder to the retiring
Subordination Agent and (y) a written assumption of its obligations hereunder
and under each Liquidity Facility to each party hereto, upon which the
resignation or removal of the retiring Subordination Agent shall become
effective, and the successor Subordination Agent shall have all the rights,
powers and duties of the Subordination Agent under this Agreement. The successor
Subordination Agent shall mail a notice of its succession to the Liquidity
Providers and the Trustees. The retiring Subordination Agent shall promptly
transfer its rights under each of the Liquidity Facilities and all of the
property and all books and records, or true, complete and correct copies
thereof, held by it as Subordination Agent to the successor Subordination Agent.

         If the Subordination Agent fails to comply with Section 6.09 (to the
extent applicable), one or more of the Trustees or one or more of the Liquidity
Providers may petition a court of competent jurisdiction for the removal of the
Subordination Agent and the appointment of a successor Subordination Agent.

         Notwithstanding the foregoing, no resignation or removal of the
Subordination Agent shall be effective unless and until a successor has been
appointed. No appointment of a successor Subordination Agent shall be effective
unless and until the Rating Agencies shall have delivered a Ratings
Confirmation.

         (b) Any corporation into which the Subordination Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Subordination Agent
shall be a party, or any corporation succeeding to all or substantially all of
the corporate trust business of the Subordination Agent, shall be the successor
of the Subordination Agent hereunder, provided that such corporation shall be
otherwise qualified and eligible under Section 6.09, without the execution or
filing of any paper or any further act on the part of any of the parties hereto.

                           SUPPLEMENTS AND AMENDMENTS

         Section 8.01 Amendments, Waivers, Etc. (a) This Agreement may not be
supplemented, amended or modified without the consent of each Trustee (acting,
except in the case of any amendment pursuant to Section 3.06(e)(v)(y) or any
amendment contemplated by the last sentence of this Section 8.01(a), with the
consent of holders of Certificates of the related Class evidencing Fractional
Undivided Interests in the related Trust aggregating not less than a majority in
interest in such Trust or as otherwise authorized pursuant to the relevant Trust
Agreement (including, without limitation, without the consent of the
Certificateholders to the extent permitted thereby, Section 9.01 of the Basic
Agreement)), the Subordination Agent and each Liquidity Provider; provided,
however, that this Agreement may be supplemented, amended or modified without
the consent of any Trustee in order (i) to cure any ambiguity or omission or to
correct any mistake, (ii) to correct or supplement any provision, or (iii) to
make any other provision in regard to matters or questions arising hereunder
that will not materially adversely affect the interests of any Trustee or the
holders of the related Class of Certificates, and without the consent of any
Liquidity Provider if such supplement, amendment or modification is in
accordance with Section 8.01(c); provided further, however, that, if such
supplement, amendment or modification (x) would directly or indirectly amend,
modify or supersede, or otherwise conflict with, Section 2.02(b), 3.06(c),
3.06(e), 3.06(f)(other than the last sentence thereof), 3.06(l), this proviso of
8.01(a), the last sentence of 8.01(a), 8.01(c) or 9.06 (collectively, the
"American Provisions"), (y) would otherwise affect the interests of a potential
Replacement Liquidity Provider or of American with respect to its ability to
replace any Liquidity Facility or with respect to its payment obligations under
any Operative Agreement or (z) is made pursuant to the last sentence of this
Section 8.01(a) or pursuant to Section 8.01(c), then such supplement, amendment
or modification shall not be effective without the additional written consent of
American. Notwithstanding the foregoing, without the consent of each
Certificateholder affected thereby and each Liquidity Provider, no supplement,
amendment or modification of this Agreement may (i) reduce the percentage of the
interest in any Trust evidenced by the Certificates issued by such Trust
necessary to consent to modify or amend any provision of this Agreement or to
waive compliance therewith or (ii), except as provided in the last sentence of
this Section 8.01(a), modify Section 2.04, 3.02 or 3.03 hereof relating to the
distribution of monies received by the Subordination Agent hereunder from the
Equipment Notes or pursuant to the Liquidity Facilities. Nothing contained in
this Section 8.01(a) shall require the consent of a Trustee at any time
following the payment of Final Distributions with respect to the related Class
of Certificates. If the Replacement Liquidity Facility for any Liquidity
Facility is to be comprised of more than one instrument as contemplated by the
definition of the term "Replacement Liquidity Facility", then each party hereto
agrees to amend this Agreement and the other Operative Agreements to incorporate
appropriate mechanics for multiple Liquidity Facilities for a single Trust.

(b) Subject to Section 2.06, if the Subordination Agent, as the registered
holder of any Equipment Notes, receives a request for its consent to any
amendment, modification, consent

                                       53
<PAGE>

or waiver under such Equipment Notes, the Indenture pursuant to which such
Equipment Notes were issued or the related Participation Agreement or other
related document, (i) if no Indenture Event of Default shall have occurred and
be continuing with respect to such Indenture, the Subordination Agent shall
request directions with respect to each series of such Equipment Notes from the
Trustee of the Trust which holds such Equipment Notes and shall vote or consent
in accordance with the directions of such Trustee and (ii) if any Indenture
Event of Default shall have occurred and be continuing with respect to such
Indenture, the Subordination Agent will exercise its voting rights as directed
by the Controlling Party, subject to Section 4.01 and 4.04; provided that no
such amendment, modification, consent or waiver shall, without the consent of
each Liquidity Provider, reduce the amount of rent, supplemental rent or
termination values payable by American under any Lease or reduce the amount of
principal or interest payable by American under any Equipment Note issued under
any Indenture in respect of an Owned Aircraft.

         (c) If Class E Certificates are issued, this Agreement shall be amended
by written agreement of the Subordination Agent and the Trustees to provide for
the subordination of such Class E Certificates to the Class A-1 Certificates,
the Class A-2 Certificates, the Class B Certificates, the Class C Certificates
and the Class D Certificates substantially in the same manner as the Class D
Certificates are subordinated hereunder to the Class A-1 Certificates, the Class
A-2 Certificates, the Class B Certificates and Class C Certificates. No such
amendment shall materially adversely affect any Trustee. The amendment to this
Agreement to give effect to the issuance of any Class E Certificates shall,
without limitation:

         (i) add the Class E Trustee as a party to this Agreement;

         (ii) revise the definitions of "Cash Collateral Account",
"Certificate", "Class", "Controlling Party", "Equipment Notes", "Final Legal
Distribution Date", "Liquidity Facility", "Liquidity Provider", "LTV Ratio",
"Stated Interest Rate", "Trust", "Trust Agreement" and "Trustee", as
appropriate, to reflect the issuance of the Class E Certificates (and the
subordination thereof); and

         (iii) revise the provisions of this Agreement governing payments with
respect to Certificates and related notices, including, without limitation,
Sections 2.04, 3.01, 3.02, 3.03 and 3.06, if necessary, to provide for
distributions on the Class E Certificates after payment of all relevant
distributions on the Class D Certificates.

If, with respect to any Aircraft, Series E Equipment Notes are issued to any
Person other than the Class E Trust, this Agreement shall be amended by written
agreement of the indenture trustees of the Series E Equipment Notes, the
Trustees and the Subordination Agent to (i) provide for each holder of a Series
E Equipment Note to be bound by the provisions of Section 2.06(a) so that the
Controlling Party, among other things, shall be entitled to direct the Loan
Trustee under the applicable Indenture as provided in such Section 2.06(a) (and
such Series E Equipment Notes shall make effective provision therefor so as to
bind each holder thereof to such provisions of Section 2.06(a)) and (ii) to
revise the definitions of "Controlling Party" and "Equipment Notes", as
appropriate, to reflect the issuance of the Series E Equipment Notes (and the
prior rights, as

                                       54
<PAGE>

against the holders of such Series E Equipment Notes, of the Class A-1 Trustee,
the Class A-2 Trustee, the Class B Trustee, the Class C Trustee and the Class D
Trustee to be such "Controlling Party"). No such amendment shall materially
adversely affect any Trustee.

         Section 8.02 Subordination Agent Protected. If, in the reasonable
opinion of the institution acting as the Subordination Agent hereunder, any

         Section 9.07 Headings. The headings of the various Articles and
Sections herein and in the Table of Contents hereto are for convenience of
reference only and shall not define or limit any of the terms or provisions
hereof.

         Section 9.08 Counterparts. This Agreement may be executed in any number
of counterparts (and each party shall not be required to execute the same
counterpart). Each counterpart of this Agreement including a signature page or
pages executed by each of the parties hereto shall be an original counterpart of
this Agreement, but all of such counterparts together constitute one instrument.

         Section 9.09 Subordination. (a) As among the Trustees, and as between
the Liquidity Providers, on the one hand, and the Trustees and the
Certificateholders, on the other hand, this Agreement shall be a subordination
agreement for purposes of Section 510 of the United States Bankruptcy Code, as
amended from time to time. In addition, as among the Trustees and the
Certificateholders of each Class, this Agreement shall be a subordination
agreement for purposes of such Section 510.

         (b) Notwithstanding the provisions of this Agreement, if prior to the
payment in full to the Liquidity Providers of all Liquidity Obligations then due
and payable or prior to the distribution in full of any other amount
distributable hereunder, any party hereto shall have received any payment or
distribution in respect of Equipment Notes or any other amount under the
Indentures or other Operative Agreements which, had the subordination provisions
of this Agreement been properly applied to such payment, distribution or other
amount, would not have been distributed to such Person, then such payment,
distribution or other amount shall be received and held in trust by such Person
and paid over or delivered to the Subordination Agent for application as
provided herein.

         (c) If any Trustee, any Liquidity Provider or the Subordination Agent
receives any payment in respect of any obligations owing or amounts
distributable hereunder (or, in the case of the Liquidity Providers, in respect
of the Liquidity Obligations), which is subsequently invalidated, declared
preferential, set aside and/or required to be repaid to a trustee, receiver or

                                       57
<PAGE>

other party, then, to the extent of such payment, such obligations or amounts
(or, in the case of the Liquidity Providers, such Liquidity Obligations)
intended to be satisfied shall be revived and continue in full force and effect
as if such payment had not been received.

         (d) The Trustees (on behalf of themselves and the holders of
Certificates), the Liquidity Providers and the Subordination Agent expressly
confirm and agree that the payment priorities and subordination specified in
Articles II and III shall apply in all circumstances, notwithstanding (x) the
fact that the obligations owed to the Trustees are secured by certain assets and
the Liquidity Obligations are not so secured and (y) the occurrence of an
American Bankruptcy Event or any similar event or occurrence relating to any
other Person (it being expressly agreed that the payment priorities and
subordination specified in Articles II and III shall apply whether or not a
claim for post-petition or post-filing interest is allowed in the proceedings
resulting from such American Bankruptcy Event or other event or occurrence). The
Trustees expressly agree (on behalf of themselves and the holders of
Certificates) not to assert priority over the holders of Liquidity Obligations
due to their status as secured creditors in any bankruptcy, insolvency or other
legal proceeding.

         (e) Each of the Trustees (on behalf of themselves and the holders of
Certificates), the Liquidity Providers and the Subordination Agent may take any
of the following actions without impairing its rights under this Agreement:

         (i) obtain a Lien on any property to secure any amounts owing to it
hereunder, including, in the case of the Liquidity Providers, the Liquidity
Obligations;

         (ii) obtain the primary or secondary obligation of any other obligor
with respect to any amounts owing to it hereunder, including, in the case of the
Liquidity Providers, any of the Liquidity Obligations;

         (iii) renew, extend, increase, alter or exchange any amounts owing to
it hereunder, including, in the case of the Liquidity Providers, any of the
Liquidity Obligations, or release or compromise any obligation of any obligor
with respect thereto;

         (iv) refrain from exercising any right or remedy, or delay in
exercising any right or remedy, which it may have; or

         (v) take any other action which might discharge a subordinated party or
a surety under applicable law;

provided, however, that the taking of any such actions by any of the Trustees,
the Liquidity Providers or the Subordination Agent shall not prejudice the
rights or adversely affect the obligations of any other party under this
Agreement.

         Section 9.10 Governing Law. THIS AGREEMENT HAS BEEN DELIVERED IN THE
STATE OF NEW YORK AND SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE
LAWS OF THE STATE OF NEW YORK, INCLUDING ALL

transactions contemplated hereby brought by any party or parties hereto or
thereto, or their successors or permitted assigns and (b) waives, and agrees not
to assert, by way of motion, as a defense, or otherwise, in any such suit,
action or proceeding, that the suit, action or proceeding is brought in an
inconvenient forum, that the venue of the suit, action or proceeding is improper
or that this Agreement or the subject matter hereof or any of the transactions
contemplated hereby may not be enforced in or by such courts.

         (b) EACH OF THE PARTIES HERETO HEREBY AGREES TO WAIVE ITS RESPECTIVE
RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT
OF THIS AGREEMENT OR ANY DEALINGS BETWEEN THEM RELATING TO THE SUBJECT MATTER OF
THIS AGREEMENT AND THE RELATIONSHIP THAT IS BEING ESTABLISHED, including,
without limitation, contract claims, tort claims, breach of duty claims and all
other common law and statutory claims. Each of the parties warrants and
represents that it has reviewed this waiver with its legal counsel, and that it
knowingly and voluntarily waives its jury trial rights following consultation
with such legal counsel. THIS WAIVER IS IRREVOCABLE AND CANNOT BE MODIFIED
EITHER ORALLY OR IN WRITING, AND THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT
AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT.

         (c) Each Liquidity Provider hereby waives any immunity it may have from
the jurisdiction of the courts of the United States or of any state thereof and
waives any immunity any of its properties located in the United States may have
from attachment or execution upon a judgment entered by any such court under the
United States Foreign Sovereign Immunities Act of 1976 or any similar successor
legislation.

Required Amount is (i) reduced as a result of a reduction in the Pool Balance of
the Class A-1 Certificates or otherwise, the Maximum Commitment shall
automatically be reduced to an amount equal to such reduced Required Amount (as
calculated by the Borrower) and (ii) increased or decreased as a result of any
increase or decrease in the Stated Interest Rate of the Class A-1 Certificates
pursuant to the definition of "Stated Interest Rate" set forth in the
Intercreditor Agreement, the Maximum Commitment shall be automatically increased
or decreased to an amount equal to such increased or decreased Required Amount
(as calculated by the Borrower). The Borrower shall give notice of

                                       11

<PAGE>

any such automatic reduction or increase of the Maximum Commitment to the
Liquidity Provider and American within two Business Days thereof. The failure by
the Borrower to furnish any such notice shall not affect any such automatic
reduction or increase of the Maximum Commitment.

         (b) Termination. Upon the making of any Provider Advance or Final
Advance hereunder or the occurrence of the Termination Date, the obligation of
the Liquidity Provider to make further Advances hereunder shall automatically
and irrevocably terminate, and the Borrower shall not be entitled to request any
further Borrowing hereunder.

         Section 2.05 Repayments of Interest Advances or the Final Advance.
Subject to Sections 2.06, 2.07 and 2.09 hereof, the Borrower hereby agrees,
without notice of an Advance or demand for repayment from the Liquidity Provider
(which notice and demand are hereby waived by the Borrower), to pay, or to cause
to be paid, to the Liquidity Provider (a) on each date on which the Liquidity
Provider shall make an Interest Advance or the Final Advance, an amount equal to
the amount of such Advance (any such Advance, until repaid, is referred to
herein as an "Unpaid Advance"), plus (b) interest on the amount of each such
Unpaid Advance in the amounts and on the dates determined as provided in Section
3.07; provided that if (i) the Liquidity Provider shall make a Provider Advance
at any time after making one or more Interest Advances which shall not have been
repaid in accordance with this Section 2.05 or (ii) this Liquidity Facility
shall become a Downgraded Facility or Non-Extended Facility at any time when
unreimbursed Interest Advances have reduced the Maximum Available Commitment to
zero, then such Interest Advances shall cease to constitute Unpaid Advances and
shall be deemed to have been changed into an Applied Downgrade Advance or an
Applied Non- Extension Advance, as the case may be, for all purposes of this
Agreement (including, without limitation, for the purpose of determining when
such Interest Advance is required to be repaid to the Liquidity Provider in
accordance with Section 2.06 and for the purposes of Section 2.06(b)). The
Borrower and the Liquidity Provider agree that the repayment in full of each
Interest Advance and Final Advance on the date such Advance is made is intended
to be a contemporaneous exchange for new value given to the Borrower by the
Liquidity Provider. For the avoidance of doubt, interest payable on an Interest
Advance or the Final Advance shall not be regarded as overdue unless such
interest is not paid when due under Section 3.07.

         Section 2.06 Repayments of Provider Advances.

         (a) Amounts advanced hereunder in respect of a Provider Advance shall
be deposited in the Class A-1 Cash Collateral Account and invested and withdrawn
from the Class A-1 Cash Collateral Account as set forth in Sections 3.06(c),
3.06(d), 3.06(e) and 3.06(f) of the Intercreditor Agreement. Subject to Sections
2.07 and 2.09, the Borrower agrees to pay to the Liquidity Provider, on each
Regular Distribution Date, commencing

                                       12

<PAGE>

on the first Regular Distribution Date after the making of a Provider Advance,
interest on the principal amount of any such Provider Advance, in the amounts
determined as provided in Section 3.07; provided, however, that amounts in
respect of a Provider Advance withdrawn from the Class A-1 Cash Collateral
Account for the purpose of paying interest on the Class A-1 Certificates in
accordance with Section 3.06(f) of the Intercreditor Agreement (the amount of
any such withdrawal being (y) in the case of a Downgrade Advance, an "Applied
Downgrade Advance" and (z) in the case of a Non- Extension Advance, an "Applied
Non-Extension Advance" and, together with an Applied Downgrade Advance, an
"Applied Provider Advance") shall thereafter (subject to Section 2.06(b)) be
treated as an Interest Advance under this Agreement for purposes of determining
the Applicable Liquidity Rate for interest payable thereon and the dates on
which such interest is payable; provided further, however, that if, following
the making of a Provider Advance, the Liquidity Provider delivers a Termination
Notice to the Borrower pursuant to Section 6.01, such Provider Advance shall
thereafter be treated as a Final Advance under this Agreement for purposes of
determining the Applicable Liquidity Rate for interest payable thereon and the
dates on which such interest is payable. Subject to Sections 2.07 and 2.09
hereof, immediately upon the withdrawal of any amounts from the Class A-1 Cash
Collateral Account on account of a reduction in the Required Amount, the
Borrower shall repay to the Liquidity Provider a portion of the Provider
Advances in a principal amount equal to such reduction, plus interest on the
principal amount prepaid as provided in Section 3.07.

         (b) At any time when an Applied Provider Advance (or any portion
thereof) is outstanding, upon the deposit in the Class A-1 Cash Collateral
Account of any amount pursuant to clause "third" of Section 2.04(b) of the
Intercreditor Agreement, clause "third" of Section 3.02 of the Intercreditor
Agreement or clause "fourth" of Section 3.03 of the Intercreditor Agreement (any
such amount being a "Replenishment Amount") for the purpose of replenishing or
increasing the balance thereof up to the Required Amount at such time, (i) the
aggregate outstanding principal amount of all Applied Provider Advances (and of
Provider Advances treated as an Interest Advance for purposes of determining the
Applicable Liquidity Rate for interest payable thereon) shall be automatically
reduced by the amount of such Replenishment Amount and (ii) the aggregate
outstanding principal amount of all Unapplied Provider Advances shall be
automatically increased by the amount of such Replenishment Amount.

         (c) Upon the provision of a Replacement Liquidity Facility in
replacement of this Agreement in accordance with Section 3.06(e) of the
Intercreditor Agreement, as provided in Section 3.06(f) of the Intercreditor
Agreement, amounts remaining on deposit in the Class A-1 Cash Collateral Account
after giving effect to any Applied Provider Advance on the date of such
replacement shall be reimbursed to the Liquidity Provider, but only to the
extent such amounts are necessary to repay in full to the Liquidity Provider all
amounts owing to it hereunder.

                                       13

<PAGE>

         Section 2.07 Payments to the Liquidity Provider Under the Intercreditor
Agreement. In order to provide for payment or repayment to the Liquidity
Provider of any amounts hereunder, the Intercreditor Agreement provides that
amounts available and referred to in Articles II and III of the Intercreditor
Agreement, to the extent payable to the Liquidity Provider pursuant to the terms
of the Intercreditor Agreement (including, without limitation, Section 3.06(f)
of the Intercreditor Agreement), shall be paid to the Liquidity Provider in
accordance with the terms thereof (but, for the avoidance of doubt, without
duplication of or increase in any amounts payable hereunder). Amounts so paid to
the Liquidity Provider shall be applied by the Liquidity Provider in the order
of priority required by the applicable provisions of Articles II and III of the
Intercreditor Agreement and shall discharge in full the corresponding
obligations of the Borrower hereunder.

         Section 2.08 Book Entries. The Liquidity Provider shall maintain in
accordance with its usual practice an account or accounts evidencing the
indebtedness of the Borrower resulting from Advances made from time to time and
the amounts of principal and interest payable hereunder and paid from time to
time in respect thereof; provided, however, that the failure by the Liquidity
Provider to maintain such account or accounts shall not affect the obligations
of the Borrower in respect of Advances.

         Section 2.09 Payments from Available Funds Only. All payments to be
made by the Borrower under this Agreement shall be made only from the amounts
that constitute Scheduled Payments, Special Payments and other payments under
the Operative Agreements, including payment under Section 4.02 of the
Participation Agreements relating to the Owned Aircraft and Section 10 of the
Participation Agreements relating to the Leased Aircraft and payments under
Section 2.14 of the Indentures, and only to the extent that the Borrower shall
have sufficient income or proceeds therefrom to enable the Borrower to make
payments in accordance with the terms hereof after giving effect to the priority
of payments provisions set forth in the Intercreditor Agreement. The Liquidity
Provider agrees that it will look solely to such amounts to the extent available
for distribution to it as provided in the Intercreditor Agreement and this
Agreement and that the Borrower, in its individual capacity, is not personally
liable to it for any amounts payable or liability under this Agreement except as
expressly provided in this Agreement, the Intercreditor Agreement or any
Participation Agreement. Amounts on deposit in the Class A-1 Cash Collateral
Account shall be available to the Borrower to make payments under this Agreement
only to the extent and for the purposes expressly contemplated in Section
3.06(f) of the Intercreditor Agreement.

         Section 2.10 Extension of the Expiry Date; Non-Extension Advance. By
written agreement between the Borrower and the Liquidity Provider, entered into
at any time prior to the 25(th) day prior to the then-effective Expiry Date
(with the written consent of Moody's, so long as Boeing Capital Corporation is
the Liquidity Provider), the then-

                                       14

<PAGE>

effective Expiry Date may be extended, effective on such 25th day (unless such
then-effective Expiry Date is on or after the date that is 15 days after the
Final Legal Distribution Date for the Class A-1 Certificates), for a period of
364 days after such then- effective Expiry Date (unless the obligations of the
Liquidity Provider are earlier terminated in accordance with the terms hereof).
If the Borrower and the Liquidity Provider do not so agree to extend the
then-effective Expiry Date, (or if Moody's does not consent to such extension,
if Boeing Capital Corporation is the Liquidity Provider) prior to such 25(th)
day (and if the Liquidity Provider shall not have been replaced in accordance
with Section 3.06(e) of the Intercreditor Agreement), the Borrower shall be
entitled on and after such 25th day (but prior to such Expiry Date) to request a
Non- Extension Advance in accordance with Section 2.02(b) hereof and Section
3.06(d) of the Intercreditor Agreement.

                                   ARTICLE III

                        OBLIGATIONS OF THE BORROWER

         Section 3.01 Increased Costs. If as a result of any Regulatory Change
or any compliance by the Liquidity Provider or its head office with any official
request or directive regarding the same (whether or not having the force of law)
there shall be (x) any increase by an amount reasonably deemed by the Liquidity
Provider to be material in the actual cost to the Liquidity Provider of making,
funding or maintaining any Advances or its obligation to make any such Advances,
(y) any reduction by an amount reasonably deemed by the Liquidity Provider to be
material in the amount receivable by the Liquidity Provider under this Agreement
or the Intercreditor Agreement in respect thereof, or (z) any reduction
reasonably deemed by the Liquidity Provider to be material in the rate of return
on the Liquidity Provider's capital as a consequence of its commitment
hereunder, its funding Advances or maintaining Unpaid Advances or its funding or
maintaining the Downgrade Advance or the Non-Extension Advance to a level below
that which the Liquidity Provider could have achieved but for such adoption,
change or compliance (taking into consideration the Liquidity Provider's
policies with respect to capital adequacy), and in case of any such an increase
or reduction, such event does not arise from the gross negligence or willful
misconduct of the Liquidity Provider, from its breach of any of its
representations, warranties, covenants or agreements contained herein or in the
Intercreditor Agreement or from its failure to comply with any such Regulatory
Change (any such increase or reduction being referred to herein as an "Increased
Cost"), then the Borrower shall from time to time pay to the Liquidity Provider
an amount equal to such Increased Cost within 15 Business Days after delivery to
the Borrower and American of a certificate of an officer of the Liquidity
Provider describing in reasonable detail the event by reason of which it claims
such Increased Cost and the basis for the determination of the amount of such
Increased Cost; provided that, the Borrower shall be obligated to pay amounts
only with respect to any Increased Costs accruing from the date 45 days prior to
the date of delivery of such certificate. Such

                                       15

<PAGE>

certificate, in the absence of manifest error, shall be considered prima facie
evidence of the amount for purposes of this Agreement; provided that any
determinations and allocations by the Liquidity Provider of the effect of any
Regulatory Change on the costs of maintaining the Advances are made on a
reasonable basis. The Liquidity Provider shall not be entitled to assert any
claim under this Section 3.01 in respect of or attributable to Taxes. The
Liquidity Provider will notify the Borrower and American as promptly as
practicable after obtaining actual knowledge of any event occurring after the
date of this Agreement that will entitle the Liquidity Provider to compensation
under this Section 3.01. The Liquidity Provider agrees to investigate all
commercially reasonable alternatives (consistent with its internal lending
policies and legal and regulatory restrictions) for reducing any Increased Costs
and to use all commercially reasonable efforts (consistent with its internal
lending policies and legal and regulatory restrictions) to avoid or minimize, to
the greatest extent possible, any claim in respect of Increased Costs,
including, without limitation, by designating a different Lending Office, if
such designation or other action would avoid the need for, or reduce the amount
of, any such claim; provided that the foregoing shall not obligate the Liquidity
Provider to take any action that would, in its reasonable judgment, cause the
Liquidity Provider to incur any material loss or cost, unless the Borrower or
American agrees to reimburse the Liquidity Provider therefor. If no such
designation or other action is effected, or, if effected, fails to avoid the
need for any claim in respect of Increased Costs, American may arrange for a
Replacement Liquidity Facility in accordance with Section 3.06(e) of the
Intercreditor Agreement.

         Notwithstanding the foregoing provisions, in no event shall the
Borrower be required to make payments under this Section 3.01: (a) in respect of
any Regulatory Change proposed by any applicable governmental authority
(including any branch of a legislature), central bank or comparable agency of
the United States or the Liquidity Provider's jurisdiction of organization and
pending as of the date of this Agreement (it being agreed that the consultative
document issued by the Basel Committee on Banking Supervision entitled "The New
Basel Capital Accord" shall not be considered a Regulatory Change proposed as of
the date of this Agreement); (b) if a claim hereunder in respect of an Increased
Cost arises through circumstances peculiar to the Liquidity Provider and that do
not affect commercial banking institutions organized in the same jurisdiction
generally that are in compliance with the law, rule, regulation or
interpretation giving rise to the Regulatory Change relating to such Increased
Cost; (c) to the extent that amounts claimed hereunder result from a failure by
the Liquidity Provider to comply with its obligations under this Section 3.01;
or (d) to the extent the Liquidity Provider is not also seeking payment for
similar increased costs in other similarly situated transactions.

         Section 3.02 [Intentionally omitted.]

                                       16

<PAGE>

         Section 3.03 Withholding Taxes.

         (a) All payments made by the Borrower under this Agreement shall be
made without deduction or withholding for or on account of any Taxes, unless
such deduction or withholding is required by law. If any Taxes are so required
to be withheld or deducted from any amounts payable to the Liquidity Provider
under this Agreement, the Borrower shall pay to the relevant authorities the
full amount so required to be deducted or withheld and, if the Liquidity
Provider is not a United States person for U.S. federal income tax purposes and
such Taxes are Covered Taxes, pay to the Liquidity Provider such additional
amounts as shall be necessary to ensure that the net amount actually received by
the Liquidity Provider (after deduction or withholding of all Covered Taxes)
shall be equal to the full amount that would have been received by the Liquidity
Provider had no withholding or deduction of Covered Taxes been required. The
Liquidity Provider agrees to use reasonable efforts (consistent with applicable
legal and regulatory restrictions) to change the jurisdiction of its Lending
Office if making such change would avoid the need for, or reduce the amount of,
any such additional amounts that may thereafter accrue and would not, in the
reasonable judgment of the Liquidity Provider, be otherwise materially
disadvantageous to the Liquidity Provider. If the Liquidity Provider receives a
refund of, or realizes and actually utilizes a net Tax benefit not otherwise
available to it as a result of, any Taxes for which additional amounts were paid
by the Borrower pursuant to this Section 3.03, the Liquidity Provider shall pay
to the Borrower (for deposit into the Collection Account) the amount of such
refund (and any interest thereon) or net benefit utilized.

         The Liquidity Provider will (i) provide (on its behalf and on behalf of
any participant holding a Participation pursuant to Section 7.08) to the
Borrower (x) on or prior to the Effective Date two valid completed and executed
copies of Internal Revenue Service Form W8-BEN or Form W-8ECI, as applicable, if
the Liquidity Provider is not a United States person for U.S. federal income tax
purposes, including thereon a valid U.S. taxpayer identification number (or,
with respect to any such participant, such form or documentation as may be
applicable) covering all amounts receivable by it in connection with the
transactions contemplated by the Operative Agreements and (y) thereafter from
time to time such additional forms or documentation as may be necessary to
establish an available exemption from withholding of United States Tax on
payments hereunder so that such forms or documentation are effective for all
periods during which it is the Liquidity Provider and (ii) provide timely notice
to the Borrower if any such form or documentation is or becomes inaccurate. The
Liquidity Provider shall deliver to the Borrower such other forms or documents
as may be reasonably requested by the Borrower or required by applicable law to
establish that payments hereunder are exempt from or entitled to a reduced rate
of Covered Taxes.

         (b) All payments (including, without limitation, Advances) made by the
Liquidity Provider under this Agreement shall be made free and clear of, and
without

                                       17

<PAGE>

reduction for or on account of, any Taxes. If any Taxes are required to be
withheld or deducted from any amounts payable to the Borrower under this
Agreement, the Liquidity Provider shall (i) within the time prescribed therefor
by applicable law pay to the appropriate governmental or taxing authority the
full amount of any such Taxes (and any additional Taxes in respect of the
additional amounts payable under clause (ii) hereof) and make such reports or
returns in connection therewith at the time or times and in the manner
prescribed by applicable law, and (ii) pay to the Borrower an additional amount
which (after deduction of all such Taxes) will be sufficient to yield to the
Borrower the full amount which would have been received by it had no such
withholding or deduction been made. Whenever any Tax is payable with respect to
a payment hereunder, as promptly as possible thereafter, the Liquidity Provider
shall furnish to the Borrower the original or a certified copy of (or other
documentary evidence of) the payment of the Taxes applicable to such payment.

         If any exemption from, or reduction in the rate of, any Taxes required
to be borne by the Liquidity Provider under this Section 3.03(b) is reasonably
available to the Borrower without providing any information regarding the
holders or beneficial owners of the Certificates, the Borrower shall deliver the
Liquidity Provider such form or forms and such other evidence of the eligibility
of the Borrower for such exemption or reductions (but without any requirement to
provide any information regarding the holders or beneficial owners of the
Certificates) as the Liquidity Provider may reasonably identify to the Borrower
as being required as a condition to exemption from, or reduction in the rate of,
such Taxes. The Borrower shall, for federal income tax purposes, treat any
Advances as a loan to the Subordination Agent on behalf of the Class A-1 Trust,
unless otherwise required by law.

         Section 3.04 Payments. The Borrower shall make or cause to be made each
payment to the Liquidity Provider under this Agreement so as to cause the same
to be received by the Liquidity Provider not later than 1:00 P.M. (New York City
time) on the day when due. The Borrower shall make all such payments in Dollars,
to the Liquidity Provider in immediately available funds, by wire transfer to:
The Chase Manhattan Bank, New York, New York; ABA #021000021; Account name:
Boeing Capital Corporation; Account number: 910 1 307412; Reference: Liquidity
Facility Fee, or to such other account as the Liquidity Provider may from time
to time direct the Subordination Agent.

         Section 3.05 Computations. All computations of interest based on the
Base Rate shall be made on the basis of a year of 365 or 366 days, as the case
may be, and all computations of interest based on the LIBOR Rate shall be made
on the basis of a year of 360 days, in each case for the actual number of days
(including the first day but excluding the last day) occurring in the period for
which such interest is payable.

         Section 3.06 Payment on Non-Business Days. Whenever any payment to be
made hereunder shall be stated to be due on a day other than a Business Day,
such

                                       18

<PAGE>

payment shall be made on the next succeeding Business Day and no additional
interest shall be due as a result (and if so made, shall be deemed to have been
made when due). If any payment in respect of interest on an Advance is so
deferred to the next succeeding Business Day, such deferral shall not delay the
commencement of the next Interest Period for such Advance (if such Advance is a
LIBOR Advance) or reduce the number of days for which interest will be payable
on such Advance on the next interest payment date for such Advance.

         Section 3.07 Interest.

         (a) Subject to Sections 2.07 and 2.09, the Borrower shall pay, or shall
cause to be paid, without duplication, interest on (i) the unpaid principal
amount of each Advance from and including the date of such Advance (or, in the
case of an Applied Provider Advance, from and including the date on which the
amount thereof was withdrawn from the Class A-1 Cash Collateral Account to pay
interest on the Class A-1 Certificates) to but excluding the date such principal
amount shall be paid in full (or, in the case of an Applied Provider Advance,
the date on which the Class A-1 Cash Collateral Account is fully replenished in
respect of such Advance) and (ii) any other amount due hereunder (whether fees,
commissions, expenses or other amounts or, to the extent permitted by law,
installments of interest on Advances or any such other amount) that is not paid
when due (whether at stated maturity, by acceleration or otherwise) from and
including the due date thereof to but excluding the date such amount is paid in
full, in each such case, at the interest rate per annum for each day equal to
the Applicable Liquidity Rate (as defined below) for such Advance or such other
amount, as the case may be, as in effect for such day, but in no event at a rate
per annum greater than the maximum rate permitted by applicable law, provided,
however, that, if at any time the otherwise applicable interest rate as set
forth in this Section 3.07 shall exceed the maximum rate permitted by applicable
law, then to the maximum extent permitted by applicable law any subsequent
reduction in such interest rate will not reduce the rate of interest payable
pursuant to this Section 3.07 below the maximum rate permitted by applicable law
until the total amount of interest accrued equals the absolute amount of
interest that would have accrued (without additional interest thereon) if such
otherwise applicable interest rate as set forth in this Section 3.07 had at all
relevant times been in effect.

         (b) Except as provided in Section 3.07(e), each Advance will be either
a Base Rate Advance or a LIBOR Advance as provided in this Section 3.07. Each
such Advance will be a Base Rate Advance for the period from the date of its
borrowing to (but excluding) the third Business Day following the Liquidity
Provider's receipt of the Notice of Borrowing for such Advance. Thereafter, such
Advance shall be a LIBOR Advance; provided that the Borrower (at the direction
of the Controlling Party, so long as the Liquidity Provider is not the
Controlling Party) may (x) convert the Final Advance into a Base Rate Advance on
the last day of an Interest Period for such Advance by giving the Liquidity
Provider no less than four Business Days' prior written notice of

                                       19

<PAGE>

such election or (y) elect to maintain the Final Advance as a Base Rate Advance
by not requesting a conversion of the Final Advance to a LIBOR Advance under
Clause (5) of the applicable Notice of Borrowing (or, if, pursuant to Section
2.06, such Final Advance is deemed to have been made without delivery of a
Notice of Borrowing, by requesting, prior to 11:00 a.m. on the first Business
Day immediately following the Borrower's receipt of the applicable Termination
Notice, that such Final Advance not be converted from a Base Rate Advance to a
LIBOR Advance).

         (c) Each LIBOR Advance shall bear interest during each Interest Period
at a rate per annum equal to the LIBOR Rate for such Interest Period plus the
Applicable Margin for such LIBOR Advance, payable in arrears on the last day of
such Interest Period and, in the event of the payment of principal of such LIBOR
Advance on a day other than such last day, on the date of such payment (to the
extent of interest accrued on the amount of principal repaid).

         (d) Each Base Rate Advance shall bear interest at a rate per annum
equal to the Base Rate plus the Applicable Margin for such Base Rate Advance,
payable in arrears on each Regular Distribution Date and, in the event of the
payment of principal of such Base Rate Advance on a day other than a Regular
Distribution Date, on the date of such payment (to the extent of interest
accrued on the amount of principal repaid).

         (e) Each outstanding Unapplied Provider Advance shall bear interest in
an amount equal to the Investment Earnings on amounts on deposit in the Class
A-1 Cash Collateral Account for such Unapplied Provider Advance on the amount of
such Unapplied Provider Advance from time to time, payable in arrears on each
Regular Distribution Date.

         (f) Each amount not paid when due hereunder (whether fees, commissions,
expenses or other amounts or, to the extent permitted by applicable law,
installments of interest on Advances but excluding Advances) shall bear interest
at a rate per annum equal to the Base Rate plus 2.00% per annum until paid.

         (g) Each change in the Base Rate shall become effective immediately.
The rates of interest specified in this Section 3.07 with respect to any Advance
or other amount shall be referred to as the "Applicable Liquidity Rate".

         Section 3.08 Replacement of Borrower. Subject to Section 5.02, from
time to time and subject to the successor Borrower's meeting the eligibility
requirements set forth in Section 6.09 of the Intercreditor Agreement applicable
to the Subordination Agent, upon the effective date and time specified in a
written and completed Notice of Replacement Subordination Agent in substantially
the form of Annex VI (a "Notice of Replacement Subordination Agent") delivered
to the Liquidity Provider by the then

                                       20

<PAGE>

Borrower, the successor Borrower designated therein shall become the Borrower
for all purposes hereunder.

         Section 3.09 Funding Loss Indemnification. The Borrower shall pay to
the Liquidity Provider, upon the request of the Liquidity Provider, such amount
or amounts as shall be sufficient (in the reasonable opinion of the Liquidity
Provider) to compensate it for any loss, cost or expense incurred by reason of
the liquidation or redeployment of deposits or other funds acquired by the
Liquidity Provider to fund or maintain any LIBOR Advance (but excluding loss of
the Applicable Margin or anticipated profits) incurred as a result of:

         (1) Any repayment of a LIBOR Advance on a date other than the last day
of the Interest Period for such Advance; or

         (2) Any failure by the Borrower to borrow a LIBOR Advance on the date
for borrowing specified in the relevant notice under Section 2.02.

         Section 3.10 Illegality. Notwithstanding any other provision in this
Agreement, if any change in any law, rule or regulation applicable to or binding
on the Liquidity Provider, or any change in the interpretation or administration
thereof by any governmental authority, central bank or comparable agency charged
with the interpretation or administration thereof, or compliance by the
Liquidity Provider with any request or directive (whether or not having the
force of law) of any such authority, central bank or comparable agency shall
make it unlawful or impossible for the Liquidity Provider to maintain or fund
its LIBOR Advances, then upon notice to the Borrower and American by the
Liquidity Provider, the outstanding principal amount of the LIBOR Advances shall
be converted to Base Rate Advances (a) immediately upon demand of the Liquidity
Provider, if such change or compliance with such request, in the reasonable
judgment of the Liquidity Provider, requires immediate conversion; or (b) at the
expiration of the last Interest Period to expire before the effective date of
any such change or request. The Liquidity Provider will notify the Borrower and
American as promptly as practicable of any event that will lead to the
conversion of LIBOR Advances to Base Rate Advances under this Section 3.10. The
Liquidity Provider agrees to investigate all commercially reasonable
alternatives (consistent with its internal lending policies and legal and
regulatory restrictions) to avoid the need for such conversion, including,
without limitation, designating a different Lending Office, if such designation
or other action would avoid the need to convert such LIBOR Advances to Base Rate
Advances; provided, that the foregoing shall not obligate the Liquidity Provider
to take any action that would, in its reasonable judgment, cause the Liquidity
Provider to incur any material loss or cost, unless the Borrower or American
agrees to reimburse the Liquidity Provider therefor. If no such designation or

against pursuant to said Sections or in such Fee Letter)), that may be imposed
on or incurred by such Liquidity Indemnitee, in any way relating to, resulting
from, or arising out of or in connection with, any action, suit or proceeding by
any third party against such Liquidity Indemnitee and relating to this
Agreement, the Fee Letter, the Intercreditor Agreement or any Participation
Agreement; provided, however, that the Borrower shall not be required to

attributable to the negligence or willful misconduct of such Liquidity
Indemnitee or any other Liquidity Indemnitee, (ii) an ordinary and usual
operating overhead expense, (iii) attributable to the failure by such Liquidity
Indemnitee or any other Liquidity Indemnitee to perform or observe any
agreement, covenant or condition on its part to be performed or observed in this

or directors shall be liable or responsible for: (i) the use which may be made
of the Advances or any acts or omissions of the Borrower or any beneficiary or
transferee in connection therewith; (ii) the validity, sufficiency or
genuineness of documents, or of any endorsement thereon, even if such documents
should prove to be in any or all respects invalid, insufficient, fraudulent or
forged; or (iii) the making of Advances by the Liquidity Provider against
delivery of a Notice of Borrowing and other documents which do not comply with
the terms hereof; provided, however, that the Borrower shall have a claim
against the Liquidity Provider, and the Liquidity Provider shall be liable to
the Borrower, to the extent of any damages suffered by the Borrower that were
the result of (A) the Liquidity Provider's willful misconduct or gross
negligence in determining whether documents presented hereunder comply with the
terms hereof or (B) any breach by the Liquidity Provider of any of the terms of
this Agreement or the Intercreditor Agreement, including, but not limited to,

delivery to it by the Borrower of a Notice of Borrowing complying with the terms
and conditions hereof.

         (b) Neither the Liquidity Provider nor any of its officers, employees
or directors or affiliates shall be liable or responsible in any respect for (i)
any error, omission, interruption or delay in transmission, dispatch or delivery
of any message or advice, however transmitted, in connection with this Agreement
or any Notice of Borrowing delivered hereunder or (ii) any action, inaction or
omission which may be taken by it in good faith, absent willful misconduct or
negligence (in which event the extent of the Liquidity Provider's potential
liability to the Borrower shall be limited as set forth in the immediately
preceding paragraph), in connection with this Agreement or any Notice of
Borrowing.

similar taxes and fees payable or determined to be payable in the United States
in connection with the execution, delivery, filing and recording of this
Agreement, any other Operative Agreement and such other documents, and agrees to
save the Liquidity Provider harmless from and against any and all liabilities
with respect to or resulting from any delay in paying or omission to pay such
taxes or fees.

         Section 7.08 Binding Effect; Participations.

         (a) This Agreement shall be binding upon and inure to the benefit of
the Borrower and the Liquidity Provider and their respective successors and
permitted assigns, except that neither the Liquidity Provider (except as
otherwise provided in this Section 7.08) nor (except as contemplated by Section

its rights or obligations hereunder or any interest herein, subject to the
Liquidity Provider's right to grant Participations pursuant to Section 7.08(b).

         (b) The Liquidity Provider agrees that it will not grant any
participation (including, without limitation, a "risk participation") (any such
participation, a "Participation") in or to all or a portion of its rights and
obligations hereunder or under the other Operative Agreements, unless all of the
following conditions are satisfied: (i) such Participation is to a Permitted
Transferee or a corporation formed under the laws of the United States or any
state thereof, (ii) such Participation is made in accordance with all applicable
laws, including, without limitation, the Securities Act of 1933, as amended, the
Trust Indenture Act of 1939, as amended, and any other applicable laws relating
to the transfer of similar interests and (iii) such Participation shall not be
made under circumstances that require registration under the Securities Act of
1933, as amended, or qualification of any indenture under the Trust Indenture
Act of 1939, as amended. Notwithstanding any such Participation, the Liquidity
Provider agrees that (1) the Liquidity Provider's obligations under the
Operative Agreements shall remain unchanged, and such participant shall have no
rights or benefits as against American or the Borrower or under any Operative
Agreement, (2) the Liquidity Provider shall remain solely responsible to the
other parties to the Operative Agreements for the performance of such
obligations, (3) the Liquidity Provider shall remain the maker of any Advances,
and the other parties to the Operative Agreements shall continue to deal solely
and directly with the Liquidity Provider in connection with the Advances and the
Liquidity Provider's rights and obligations under the Operative Agreements, (4)
the Liquidity Provider shall be solely responsible for any withholding Taxes or
any filing or reporting requirements relating to such Participation and shall
hold the Borrower and American and their respective successors, permitted
assigns, affiliates, agents and servants harmless against the same and (5)
neither American nor the Borrower shall be required to pay to the Liquidity
Provider any amount under Section 3.01 or Section 3.03 greater than it would
have been required to pay had there not been any grant of a Participation by the
Liquidity Provider. The Liquidity Provider may, in connection with any
Participation or proposed

                                       28

<PAGE>

Participation pursuant to this Section 7.08(b), disclose to the participant or
proposed participant any information relating to the Operative Agreements or to
the parties thereto furnished to the Liquidity Provider thereunder or in
connection therewith and permitted to be disclosed by the Liquidity Provider;
provided, however, that prior to any such disclosure, the participant or
proposed participant shall agree in writing for the express benefit of the
Borrower and American to preserve the confidentiality of any confidential
information included therein (subject to customary exceptions).

         (c) Notwithstanding the other provisions of this Section 7.08, the
Liquidity Provider may assign and pledge all or any portion of the Advances
owing to it to any Federal Reserve Bank or the United States Treasury as
collateral security pursuant to Regulation A of the Board of Governors of the
Federal Reserve System and any Operating Circular issued by such Federal Reserve
Bank, provided that any payment in respect of such assigned Advances made by the
Borrower to the Liquidity Provider in accordance with the terms of this
Agreement shall satisfy the Borrower's obligations hereunder in respect of such
assigned Advance to the extent of such payment. No such assignment shall release
the Liquidity Provider from its obligations hereunder.

         Section 7.09 Severability. Any provision of this Agreement 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.

STATE OF NEW YORK AND THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, INCLUDING ALL MATTERS OF
CONSTRUCTION, VALIDITY AND PERFORMANCE, AND THE OBLIGATIONS, RIGHTS AND REMEDIES

         Section 7.11 Submission to Jurisdiction; Waiver of Jury Trial; Waiver
of Immunity.

         (a) Each of the parties hereto, to the extent it may do so under
applicable law, for purposes hereof hereby (i) irrevocably submits itself to the
non-exclusive jurisdiction of the courts of the State of New York sitting in the
City of New York and to the non- exclusive jurisdiction of the United States

brought in an inconvenient forum, that the venue of the suit, action or
proceeding is improper or that this Agreement or the subject matter hereof or
any of the transactions contemplated hereby may not be enforced in or by such
courts.

         (b) THE BORROWER AND THE LIQUIDITY PROVIDER EACH HEREBY AGREE TO WAIVE
THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED
UPON OR ARISING OUT OF THIS AGREEMENT OR ANY DEALINGS BETWEEN THEM RELATING TO
THE SUBJECT MATTER OF THIS AGREEMENT AND THE RELATIONSHIP THAT IS BEING

waiver with its legal counsel, and that it knowingly and voluntarily waives its
jury trial rights following consultation with such legal counsel. THIS WAIVER IS
IRREVOCABLE, AND CANNOT BE MODIFIED EITHER ORALLY OR IN WRITING, AND THIS WAIVER

the jurisdiction of the courts of the United States or of any state thereof and
waives any immunity any of its properties located in the United States may have
from attachment or execution upon a judgment entered by any such court under the
United States Foreign Sovereign Immunities Act of 1976 or any similar successor
legislation.

counterpart). Each counterpart of this Agreement including a signature page or
pages executed by each of the parties hereto shall be an original counterpart of
this Agreement, but all of such counterparts together shall constitute one
instrument.

         Section 7.13 Entirety. This Agreement and the Intercreditor Agreement
