         Section 2.02 Making of Advances.

         (a) Each Interest Advance shall be made by the Liquidity Provider upon
delivery to the Liquidity Provider of a written and completed Notice of
Borrowing in substantially the form of Annex I, signed by a Responsible Officer
of the Borrower, such Interest Advance to be in an amount not exceeding the
Maximum Available Commitment at such time and used solely for the payment when
due of interest with respect to the Class A-1 Certificates at the Stated
Interest Rate therefor in accordance with Section 3.06(a) and 3.06(b) of the
Intercreditor Agreement. Each Interest Advance made hereunder shall
automatically reduce the Maximum Available Commitment and the amount available
to be borrowed hereunder by subsequent Advances by the amount of such Interest
Advance (subject to reinstatement as provided in the next sentence). Upon
repayment to the Liquidity Provider in full or in part of the amount of any
Interest Advance made pursuant to this Section 2.02(a), together with accrued
interest thereon (as provided herein), the Maximum Available Commitment shall be
reinstated by an amount equal to the amount of such Interest Advance so repaid,
but not to exceed the Maximum Commitment; provided, however, that the Maximum
Available Commitment shall not be so reinstated at any time if (x) both a
Performing Note Deficiency exists and a Liquidity Event of Default shall have
occurred and be continuing or (y) a Final Drawing shall have occurred.

         (b) Subject to Section 2.10, a Non-Extension Advance shall be made by
the Liquidity Provider if this Agreement is not extended in accordance with
Section 3.06(d) of the Intercreditor Agreement (unless a Replacement Liquidity
Facility to replace this Agreement shall have been delivered to the Borrower as
contemplated by said Section 3.06(d) within the time period specified in such
Section 3.06(d)) upon delivery to the Liquidity Provider of a written and
completed Notice of Borrowing in substantially the form of Annex II, signed by a
Responsible Officer of the Borrower, in an amount equal to the Maximum Available
Commitment at such time, and shall be used to fund the Class A-1 Cash Collateral
Account in accordance with Sections 3.06(d) and 3.06(f) of the Intercreditor
Agreement.

         (c) A Downgrade Advance shall be made by the Liquidity Provider if at
any time the short-term unsecured debt rating of the Liquidity Provider issued
by either Rating Agency (or if the Liquidity Provider does not have a short-term
unsecured debt rating issued by a given Rating Agency, the long-term unsecured
debt rating of the Liquidity Provider issued by such Rating Agency) is lower
than the applicable Threshold Rating (as provided for in Section 3.06(c) of the
Intercreditor Agreement) unless a Replacement Liquidity Facility to replace this
Agreement shall have been previously delivered to the Borrower in accordance
with said Section 3.06(c), upon delivery to the Liquidity Provider of a written
and completed Notice of Borrowing in substantially the form of Annex III, signed
by a Responsible Officer of the Borrower, in an amount equal to the Maximum
Available Commitment at such time, and shall be used to fund the Class A-1 Cash
Collateral Account in accordance with Sections 3.06(c) and 3.06(f) of the
Intercreditor Agreement.

         (d) A Final Advance shall be made by the Liquidity Provider following
the receipt by the Borrower of a Termination Notice from the Liquidity Provider
pursuant to Section 6.01 upon delivery to the Liquidity Provider of a written
and completed Notice of Borrowing in substantially the form of Annex IV, signed
by a Responsible Officer of the Borrower, in an amount equal to the Maximum
Available Commitment at such time, and shall be used to fund


                                       8
<PAGE>


the Class A-1 Cash Collateral Account in accordance with Sections 3.06(f) and
3.06(i) of the Intercreditor Agreement.

         (e) Each Borrowing shall be made on notice in writing (a "Notice of
Borrowing") in substantially the form required by Section 2.02(a), 2.02(b),
2.02(c) or 2.02(d), as the case may be, given by the Borrower to the Liquidity
Provider. Each Notice of Borrowing shall be effective upon delivery of a copy
thereof to the Liquidity Provider's office at the address specified in Section
7.02 hereof. If a Notice of Borrowing is delivered by the Borrower in respect of
any Borrowing no later than 1:00 p.m. (New York City time) on a Business Day,
upon satisfaction of the conditions precedent set forth in Section 4.02 with
respect to a requested Borrowing, the Liquidity Provider shall make available to
the Borrower, in accordance with its payment instructions, the amount of such
Borrowing in Dollars and immediately available funds, before 4:00 p.m. (New York
City time) on such Business Day or before 1:00 p.m. (New York City time) on such
later Business Day specified in such Notice of Borrowing. If a Notice of
Borrowing is delivered by the Borrower in respect of any Borrowing after 1:00
p.m. (New York City time) on a Business Day, upon satisfaction of the conditions
precedent set forth in Section 4.02 with respect to a requested Borrowing, the
Liquidity Provider shall make available to the Borrower, in accordance with its
payment instructions, the amount of such Borrowing in Dollars and immediately
available funds, before 1:00 p.m. (New York City time) on the first Business Day
next following the day of receipt of such Notice of Borrowing or on such later
Business Day specified by the Borrower in such Notice of Borrowing. Payments of
proceeds of a Borrowing shall be made by wire transfer of immediately available
funds to the Borrower in accordance with such wire transfer instructions as the
Borrower shall furnish from time to time to the Liquidity Provider for such
purpose. Each Notice of Borrowing shall be irrevocable and binding on the
Borrower.

         (f) Upon the making of any Advance requested pursuant to a Notice of
Borrowing in accordance with the Borrower's payment instructions, the Liquidity
Provider shall be fully discharged of its obligation hereunder with respect to
such Notice of Borrowing, and the Liquidity Provider shall not thereafter be
obligated to make any further Advances hereunder in respect of such Notice of
Borrowing to the Borrower or to any other Person (including the Trustee or any
Class A-1 Certificateholder). If the Liquidity Provider makes an Advance
requested pursuant to a Notice of Borrowing before 12:00 noon (New York City
time) on the second Business Day after the date of payment specified in Section
2.02(e), the Liquidity Provider shall have fully discharged its obligations
hereunder with respect to such Advance and an event of default shall not have
occurred hereunder. Following the making of any Advance pursuant to Section
2.02(b), 2.02(c) or 2.02(d) to fund the Class A-1 Cash Collateral Account, the
Liquidity Provider shall have no interest in or rights to the Class A-1 Cash
Collateral Account, such Advance or any other amounts from time to time on
deposit in the Class A-1 Cash Collateral Account; provided that the foregoing
shall not affect or impair the obligations of the Subordination Agent to make
the distributions contemplated by Section 3.06(e) or 3.06(f) of the
Intercreditor Agreement and provided further, that the foregoing shall not
affect or impair the rights of the Liquidity Provider to provide written
instructions with respect to the investment and reinvestment of amounts in the
Class A-1 Cash Collateral Account to the extent provided in Section 2.02(b) of
the Intercreditor Agreement. By paying to the Borrower proceeds of Advances
requested by the Borrower in accordance with the provisions of this Agreement,
the


                                       9
<PAGE>


Liquidity Provider makes no representation as to, and assumes no responsibility
for, the correctness or sufficiency for any purpose of the amount of the
Advances so made and requested.


         Section 2.03 Fees. The Borrower agrees to pay to the Liquidity Provider
the fees set forth in the WestLB Fee Letter.


         Section 2.04 Reduction, Increase or Termination of the Maximum
Commitment.


         (a) Automatic Reduction or Increase. Promptly following each date on
which the 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 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


                                       10
<PAGE>


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 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 all purposes hereunder, including 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


                                       11
<PAGE>


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.

         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. At
any time during the period no later than the 25th day and no earlier than the
60th day prior to the then-effective Expiry Date, the Borrower may provide
notice to the Liquidity Provider and the Liquidity Provider may provide notice
to the Borrower of the then-effective Expiry Date. If the Expiry Date is prior
to the date that is 15 days after the Final Legal Distribution Date for the
Class A-1 Certificates, by written agreement between the Borrower and the
Liquidity Provider, entered into at any time prior to the 25th day prior to the
then-effective Expiry Date, the then-effective Expiry Date may be extended,
effective on such 25th day, to the earlier of (i) the date



                                       12
<PAGE>



that is 15 days after the Final Legal Distribution Date for the Class A-1
Certificates and (ii) the date that is the last day of the 364 day period
immediately following such then-effective Expiry Date (unless in either case 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 prior to such 25th 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 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 in the amount receivable by the Liquidity Provider
under this Agreement or the Intercreditor Agreement in respect thereof, or (z)
any reduction 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 120 days prior to the date of delivery of
such certificate. Such 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



                                       13
<PAGE>



efforts (consistent with its internal lending policies and legal and regulatory
restrictions) to avoid or reduce, to the 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 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 known to the officers of the Liquidity Provider 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
similar 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]

         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 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 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



                                       14
<PAGE>


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,
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 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


                                       15

Borrower shall make all such payments in Dollars, to the Liquidity Provider in
immediately available funds, by wire transfer to: The Chase Manhattan Bank, ABA
#021-000-021, for the account of Westdeutsche Landesbank Girozentrale, New York
Branch, Account Number: 920-1-060663, Reference: American Airlines, Inc. EETC
2001-1; 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 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) 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



                                       16
<PAGE>



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 (i) an
Applied Provider Advance shall always be a LIBOR Advance unless the Borrower
elects otherwise and (ii) 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 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) [Intentionally omitted]

         (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, 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(f) 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(f) below the maximum rate
permitted by law until the 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(f) had
at all relevant times been in effect.


         (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 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
other action is effected, or, if effected, fails to avoid the need for
conversion of the LIBOR Advances to Base Rate Advances, American may arrange for
a Replacement Liquidity Facility in accordance with Section 3.06(e) of the
Intercreditor Agreement.

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,
the Liquidity Provider's failure to make lawful payment hereunder after the
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.


         Section 7.07 Certain Costs and Expenses. The Borrower agrees promptly
to pay, or cause to be paid, (a) on the Effective Date and on such later date or

with the preparation, negotiation, execution, delivery, filing and



                                       23
<PAGE>



recording of this Agreement, any other Operative Agreements, any other documents
which may be delivered in connection with this Agreement, any waiver or consent
thereunder or any amendment thereof and (b) if a Liquidity Event of Default
occurs, all out-of-pocket expenses incurred by the Liquidity Provider, including
reasonable fees and disbursements of counsel, in connection with such Liquidity
Event of Default and any collection, bankruptcy, insolvency and other
enforcement proceedings in connection therewith. In addition, the Borrower shall
pay any and all recording, stamp and other 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 in connection with this Agreement, 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
3.08) the Borrower shall have the right to assign, pledge or otherwise transfer
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, (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 Participation pursuant to this Section 7.08(b),
disclose to the participant or proposed participant



                                       24
<PAGE>


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
