      This INTERCREDITOR AGREEMENT, dated as of October 4, 2001 is made by and
among STATE STREET BANK AND TRUST COMPANY OF CONNECTICUT, NATIONAL ASSOCIATION,

      WHEREAS, pursuant to each Indenture with respect to an Aircraft, American

of any Trust on any Current Distribution Date, the sum of (x) accrued and unpaid
interest in respect of such Certificates (excluding interest, if any, payable
with respect to the Deposits related to such Trust) and (y) the greater of:

      (A) the difference between (x) the Pool Balance of such Certificates as of
the immediately preceding Distribution Date (or, if the Current Distribution
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
the Current Distribution Date calculated on the basis that (i) the principal of

effect to any reduction in the Pool Balance as a result of any distribution
attributable to Deposits with respect to such Trust occurring after the
immediately preceding Distribution Date (or, if the Current Distribution Date is
the first Distribution Date, occurring after the initial issuance of the
Certificates of such Trust), and

      (B) the amount of the excess, if any, of (i) the Pool Balance of such
Class of Certificates as of the immediately preceding Distribution Date (or, if

aggregate face amount of the Certificates of such Trust), less the amount of the
Deposits for such Class of Certificates as of such preceding Distribution Date

Aircraft, clause (B) shall not apply.

      For purposes of calculating Adjusted Expected Distributions with respect
to the Certificates of any Trust, any premium paid on the Equipment Notes held
in such Trust that has not been distributed to the Certificateholders of such

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

Distributions.

Distribution Date means an amount, not less than zero, equal to the product of
(i) the sum of the applicable LTV Collateral Amounts for such Class of
Certificates for all Aircraft, minus the Pool Balance for each Class of
Certificates, if any, senior to such Class, after giving effect to any
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.

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
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.

or (f) of Section 2.14 of any Indenture), in any such case directly to the Payee

      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 a Majority in Interest of Noteholders of such
Equipment Notes (provided that, for so long as the Subordination Agent is the
registered holder of such Equipment

                                       28
<PAGE>
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, an outstanding principal amount of
such Equipment Notes that, if held by such Trustees directly, would make such
Trustees a Majority in Interest of Noteholders), 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 (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

                                       29
<PAGE>
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.

      Section 3.04 Other Payments. (a) Any payments received by the
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
of priority specified in Section 3.03; provided, however, that to the extent any
such payments are received or realized at any time after the Final Distributions
for all Classes of Certificates have been made, such payments shall be
distributed in the following order of priority: first, in the manner provided in
clause "first" of Section 3.03 and second, in the manner provided in clause
"eleventh" of Section 3.02.

      (b) On any Interest Payment Date under each Liquidity Facility which is
not a Distribution Date, the Subordination Agent shall pay to the Liquidity
Provider under such Liquidity Facility from, and to the extent of, amounts on
deposit in the Collection Account, an amount equal to the amount of interest
then due and payable to such Liquidity Provider under such Liquidity Facility.

      (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.

      (d) Any payments received by the Subordination Agent that are attributable
to the Deposits relating to any Trust or any accrued interest thereon shall be
paid over to the Paying Agent for application in accordance with the relevant
Escrow and Paying Agent Agreement.

      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) (excluding interest, if any, payable with respect to the Deposits
related to each Trust) then, prior to 1:00 p.m.

                                       37
<PAGE>
(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
Drawing under the Class A-2 Liquidity Facility and all amounts withdrawn by the
Subordination Agent from the Class A-2 Cash Collateral Account, and payable in
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 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. For
the avoidance of doubt, Interest Drawings and Applied Provider Advances (as
defined in the Liquidity Facilities) to be applied in respect of the payment of
interest with respect to the Certificates shall not include any amount of
interest due and payable on the Deposits.

      (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 or of the debt ratings of any Liquidity
Guarantor to the Subordination Agent and American. If at any time (i) if there
is no Liquidity Guarantor, 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 or (ii) if there is a
Liquidity Guarantor, the short-term unsecured debt rating of the Liquidity
Guarantor issued by either Rating Agency is lower than the applicable Threshold
Rating or a Liquidity Guarantee Event for such Liquidity Facility has occurred
and is continuing, within 10 days after the date of such downgrading or
Liquidity Guarantee Event (or within 45 days after the date of such downgrading
solely in the event of a downgrading of such Liquidity Provider's (or, if
applicable, the Liquidity Guarantor'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 (or guaranteed by the
downgraded Liquidity Guarantor or affected by a Liquidity Guarantee Event) (the
"Downgraded Facility")), such Liquidity Provider or American may arrange for a
Replacement Liquidity Provider to issue and deliver a

                                       38
<PAGE>
Replacement Liquidity Facility to the Subordination Agent, subject to the
Ratings Confirmation. 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 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. 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

                                       39
<PAGE>
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, except pursuant
to a replacement of the Class C Liquidity Provider described in paragraph 6 of
Exhibit A, and provided further, however, that, except pursuant to a replacement
of the Class C Liquidity Provider described in paragraph 6 of Exhibit A, 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 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

                                       40
<PAGE>
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 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.

                                       41

      (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)

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 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

deposit in the Class C Cash Collateral Account;

      (v) on each date on which the Pool Balance of the Class A-1 Trust shall
have been reduced by payments made to the Class A-1 Certificateholders pursuant

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

shall have been paid in full, and deposit any remaining amount in the Collection
Account; and

      (x) following the payment of Final Distributions with respect to any Class
of Certificates, on the date on which the Subordination Agent shall have been
notified by the Liquidity Provider for such Class of Certificates that the
Liquidity Obligations owed to such

                                       44
<PAGE>
Liquidity Provider have been paid in full, the Subordination Agent shall
withdraw all amounts on deposit in the Cash Collateral Account in respect of
such Class of Certificates and deposit such amount in the Collection Account.

      (g) Reinstatement. With respect to any Interest Drawing under the
Liquidity Facility for any Trust, upon the reimbursement of the applicable
Liquidity Provider for all or any part of the amount of such Interest Drawing,
together with any accrued interest thereon, the Available Amount of such
Liquidity Facility shall be reinstated by an amount equal to the amount of such
Interest Drawing so reimbursed to the applicable Liquidity Provider but not to
exceed the Stated Amount for such Liquidity Facility; provided, however, that
the Available Amount of such Liquidity Facility shall not be so reinstated in
part or in full at any time if (x) both a Performing Note Deficiency exists and
a Liquidity Event of Default shall have occurred and be continuing with respect
to the relevant Liquidity Facility or (y) a Final Drawing shall have occurred
with respect to such Liquidity Facility. In the event that, with respect to any
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
Liquidity Facility, shall be deposited in such Cash Collateral Account as and to
the extent provided in clause "third" of Section 2.04(b), clause "third" of
Section 3.02 or clause "fourth" of Section 3.03, as applicable, and applied in
accordance with Section 3.06(f).

      (h) Reimbursement. The amount of each drawing under the Liquidity
Facilities shall be due and payable, together with interest thereon, on the
dates and at the rates, respectively, provided in the Liquidity Facilities.

      (i) Final Drawing. Upon receipt from a Liquidity Provider of a 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 3.06(f).

      (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.

                                       45
<PAGE>
      (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 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) 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
(other than the Trustee of a Trust all of the Certificates of which are held or
beneficially owned by American and/or its affiliates) 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.

      (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

                                       46
<PAGE>
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 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

                                       47
<PAGE>
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, 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

                                       48
<PAGE>
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.

                                   ARTICLE VI

                             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.

<PAGE>
      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.

      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.

                                       50
<PAGE>
      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 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

                          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;

                                       51
<PAGE>
      (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.

      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) or Section 8.01(d) and Exhibit A hereto;
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), 8.01(d) 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) or 8.01(d), 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) or Section 8.01(d), 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 or

                                       53
<PAGE>
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 principal or interest payable by
American under any Equipment Note.

      (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,

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 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.

Agreement, Fee Letter, Series C Equipment Notes, and Series D Equipment Notes,
including without limitation, to reflect the new date and other identifying
characteristics of any substituted agreement; and

      (ii) revise the definitions of Stated Interest Rate and Final Legal
Distribution Date to reflect the terms of the new Certificates.

No Refunding shall adversely affect any right or obligation of the Class A-1
Liquidity Provider, Class A-2 Liquidity Provider or Class B Liquidity Provider
except as contemplated by paragraph 2 of Exhibit A. Prior to the termination or
replacement of the Class C Liquidity Provider in connection with a Refunding,
all of the Liquidity Obligations owed or payable to such Class C Liquidity
Provider must be paid in full.

of the institution acting as the Subordination Agent hereunder, any document
required to be executed by it pursuant to the terms of Section 8.01 adversely

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

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

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

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:

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.
