                                   ARTICLE II

                       AMOUNT AND TERMS OF THE COMMITMENT

      Section 2.01 The Advances. The Primary Liquidity Provider hereby
irrevocably agrees, on the terms and conditions hereinafter set forth, to make
Advances to the Borrower from time to time on any Business Day during the period
from the Effective Date until 12:00 noon (New York City time) on the Expiry Date
(unless the obligations of the Primary Liquidity Provider shall be earlier
terminated in accordance with the terms of Section 2.04(b)) in an aggregate
amount at any time outstanding not to exceed the Maximum Commitment.

      Section 2.02 Making of Advances.

      (a)   Each Interest Advance shall be made by the Primary Liquidity
Provider upon delivery to the Primary 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 G 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). Subject to
the


                                       8
<PAGE>
provisions of Section 3.06(g) of the Intercreditor Agreement, upon repayment to
the Primary 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 Primary Liquidity Provider if this Agreement is not extended in accordance
with Section 3.06(d) of the Intercreditor Agreement (unless a Replacement
Primary 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 Primary 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 G Primary Cash Collateral Account in accordance with Sections
3.06(d) and 3.06(f) of the Intercreditor Agreement.

      (c)   If at any time the short-term issuer credit rating (with respect to
S&P) or short-term unsecured debt rating (with respect to Moody's) of the
Primary Liquidity Provider issued by either Rating Agency (or if the Primary
Liquidity Provider does not have such a rating issued by a given Rating Agency,
the long-term issuer credit rating (with respect to S&P) or long-term unsecured
debt rating (with respect to Moody's) of the Primary Liquidity Provider) is
lower than the Threshold Rating (as provided for in Section 3.06(c) of the
Intercreditor Agreement), a Downgrade Advance shall be made by the Primary
Liquidity Provider on the 10th day following such downgrade (or, if such 10th
day is not a Business Day, on the next succeeding Business Day), unless a
Replacement Primary 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 Primary 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 G Primary 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 Primary Liquidity Provider
following the receipt by the Borrower of a Termination Notice from the Primary
Liquidity Provider pursuant to Section 6.01 upon delivery to the Primary
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 the Class G Primary Cash Collateral Account in
accordance with Sections 3.06(f) and 3.06(i) of the Intercreditor Agreement.


                                       9
<PAGE>
      (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 Primary
Liquidity Provider. Each Notice of Borrowing shall be effective upon delivery of
a copy thereof to the Primary Liquidity Provider's office at the address
specified in Section 7.02. 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 Primary 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 Primary 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
Primary 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 Primary
Liquidity Provider shall be fully discharged of its obligation hereunder with
respect to such Notice of Borrowing, and the Primary 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 G Certificateholder). If the Primary 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 Primary 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 G
Primary Cash Collateral Account, the Primary Liquidity Provider shall have no
interest in or rights to the Class G Primary Cash Collateral Account, such
Advance or any other amounts from time to time on deposit in the Class G Primary
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 Primary Liquidity Provider to provide written instructions with respect to
the investment and reinvestment of amounts in the Class G Primary 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 Primary


                                       10
<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 Primary Liquidity
Provider the fees set forth in the Fee Letter.

      Section 2.04 Reduction or Termination of the Maximum Commitment.

      (a)   Automatic Reduction. Promptly following each date on which the
Required Amount is reduced as a result of a reduction in the Pool Balance of the
Class G Certificates (including by reason of a Policy Provider Election with
respect to one or more Series G Equipment Notes) or otherwise, the Maximum
Commitment shall automatically be reduced to an amount equal to such reduced
Required Amount (as calculated by the Borrower). The Borrower shall give notice
of any such automatic reduction of the Maximum Commitment to the Primary
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 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 Primary 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 Primary Liquidity Provider
(which notice and demand are hereby waived by the Borrower), to pay, or to cause
to be paid, to the Primary Liquidity Provider (a) on each date on which the
Primary 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 Primary 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 Agreement 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 Primary Liquidity Provider in accordance with Section 2.06 and for the
purposes of Section 2.06(b)). The Borrower and the Primary 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 Primary Liquidity Provider. For the
avoidance of doubt, interest


                                       11
<PAGE>
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 G Primary Cash Collateral Account and invested and
withdrawn from the Class G Primary 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 Primary
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 G Primary Cash Collateral Account for
the purpose of paying interest with respect to the Class G 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
Primary 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 G Primary Cash Collateral Account on
account of a reduction in the Required Amount, the Borrower shall repay to the
Primary 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 G Primary 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.


                                       12

      (c)   Upon the provision of a Replacement Primary 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 G Primary Cash Collateral
Account after giving effect to any Applied Provider Advance on the date of such
replacement shall be reimbursed to the Primary Liquidity Provider, but only to
the extent such amounts are necessary to repay in full to the Primary Liquidity
Provider all amounts owing to it hereunder.

      Section 2.07 Payments to the Primary Liquidity Provider Under the
Intercreditor Agreement. In order to provide for payment or repayment to the
Primary 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 Primary 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 Primary 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 Primary Liquidity Provider shall be
applied by the Primary 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 Primary 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 Primary
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 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 Primary 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 G Primary 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 Primary Liquidity Provider and the Primary 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 G Certificates, by written agreement between the Borrower and the
Primary 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 that is 15
days after the Final Legal Distribution Date for the Class G 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
Primary Liquidity Provider are earlier terminated in accordance with the terms
hereof). If the Borrower and the Primary Liquidity Provider do not so agree to
extend the then-effective Expiry Date prior to such 25th day (and if the Primary
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
there shall be any increase by an amount reasonably deemed by the Primary
Liquidity Provider to be material in the actual cost to the Primary Liquidity
Provider of making, funding or maintaining any Advances or its obligation to
make any such Advances, or there shall be any reduction by an amount reasonably
deemed by the Primary Liquidity Provider to be material in (x) its return on
capital or equity or (y) the amount receivable by the Primary Liquidity Provider
under this Agreement or the Intercreditor Agreement in respect thereof, and in
the case of any such increase or reduction, such event does not arise from the
gross negligence or willful misconduct of the Primary 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 Primary 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 Primary Liquidity Provider describing in reasonable detail the
event by reason of which it claims such Increased Cost and the basis for the
determination of the amount of such Increased Cost; provided that, the Borrower
shall be obligated to pay amounts only with respect to any Increased Costs
accruing from the date 45 days prior to the date of delivery of such
certificate. Such 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 Primary Liquidity
Provider of the effect of any Regulatory Change on the costs of maintaining the


                                       14
<PAGE>
Advances are made on a reasonable basis. The Primary Liquidity Provider shall
not be entitled to assert any claim under this Section 3.01 in respect of or
attributable to Taxes. The Primary Liquidity Provider will notify the Borrower
and American as promptly as practicable of any event occurring after the date of
this Agreement that will entitle the Primary Liquidity Provider to compensation
under this Section 3.01. The Primary Liquidity Provider agrees to investigate
all commercially reasonable alternatives for reducing any Increased Costs and to
use all commercially reasonable efforts 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 Primary Liquidity Provider to
take any action that would, in its reasonable judgment, cause the Primary
Liquidity Provider to incur any material loss or cost, unless the Borrower or
American agrees to reimburse the Primary 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 Primary Liquidity Facility in accordance with Section 3.06(e) of the
Intercreditor Agreement.

      Notwithstanding the foregoing provisions, in no event shall the Borrower
be required to make payments under this Section 3.01: (a) in respect of any
Regulatory Change proposed by any applicable governmental authority (including
any branch of a legislature), central bank or comparable agency of the United
States or the Primary 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 Primary 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) if the Primary Liquidity Provider shall fail to comply with its
obligations under this Section 3.01; or (d) if the Primary 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 Primary 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 Primary Liquidity Provider such additional amounts as
shall be necessary to ensure that the net amount actually received by the
Primary Liquidity Provider (after deduction or


                                       15
<PAGE>
withholding of all Covered Taxes) shall be equal to the full amount that would
have been received by the Primary Liquidity Provider had no withholding or
deduction of Covered Taxes been required. The Primary 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 Primary Liquidity Provider, be otherwise materially disadvantageous to the
Primary Liquidity Provider. If the Primary 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 Primary Liquidity Provider shall pay to the Borrower (for
deposit into the Collection Account) the amount of such refund (and any interest
thereon) or net benefit utilized.

      The Primary 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 Primary Liquidity Provider and (ii) provide
timely notice to the Borrower if any such form or documentation is or becomes
inaccurate. The Primary 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
Primary 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 Primary 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 Primary 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 Primary 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


                                       16
<PAGE>
Borrower shall deliver the Primary 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 Primary 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 G Trust, unless otherwise
required by law.

      Section 3.04 Payments. The Borrower shall make or cause to be made each
payment to the Primary Liquidity Provider under this Agreement so as to cause
the same to be received by the Primary Liquidity Provider not later than 1:00
P.M. (New York City time) on the day when due. The Borrower shall make all such
payments in Dollars, to the Primary Liquidity Provider in immediately available
funds, by wire transfer to: JP Morgan Chase, ABA #021 000 021 for the account of
WestLB AG New York Branch, Account Number: 920-1-060663, Reference: American
Airlines, Inc. EETC 2002-1 LF-GSF Transportation (69170); or to such other
account as the Primary 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 G Primary Cash Collateral Account to
pay interest on the Class G 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 G Primary 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


                                       17
<PAGE>
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 from the date of its borrowing to (but excluding) the third
Business Day following the Primary Liquidity Provider's receipt of the Notice of
Borrowing for such Advance. Thereafter, such Advance shall be 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)   [Reserved.]

      (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 4.5% 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


                                       18
<PAGE>
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 ("Notice of Replacement Subordination Agent") delivered to
the Primary 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
Primary Liquidity Provider, upon the request of the Primary Liquidity Provider,
such amount or amounts as shall be sufficient (in the reasonable opinion of the
Primary 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 Primary 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 Primary 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 Primary 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 Primary Liquidity Provider
to maintain or fund its LIBOR Advances, then upon notice to the Borrower and
American by the Primary Liquidity Provider, the outstanding principal amount of
the LIBOR Advances shall be converted to Base Rate Advances (a) immediately upon
demand of the Primary Liquidity Provider, if such change or compliance with such
request, in the reasonable judgment of the Primary 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 Primary
Liquidity Provider will notify the Borrower and American as promptly as
practicable of any


                                       19
<PAGE>
event that will lead to the conversion of LIBOR Advances to Base Rate Advances
under this Section 3.10. The Primary Liquidity Provider agrees to investigate
all commercially reasonable alternatives 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
Primary Liquidity Provider to take any action that would, in its reasonable
judgment, cause the Primary Liquidity Provider to incur any material loss or
cost, unless the Borrower or American agrees to reimburse the Primary 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.

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 Primary 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 Primary Liquidity Provider, and the Primary 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 Primary Liquidity Provider's
willful misconduct or negligence in determining whether documents presented
hereunder comply with the terms hereof or (B) any breach by the Primary
Liquidity Provider of any of the terms of this Agreement or the Intercreditor
Agreement, including, but not limited to, the Primary 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 Primary 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
Primary 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 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, and agrees


                                       25

      Section 7.08 Binding Effect; Participations.

      (a)   This Agreement shall be binding upon and inure to the benefit of the
Borrower and the Primary Liquidity Provider and their respective successors and
permitted assigns, except that neither the Primary 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
Primary Liquidity Provider's right to grant Participations pursuant to Section
7.08(b).

      (b)   The Primary 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 Primary
Liquidity Provider agrees that (1) the Primary 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 Primary Liquidity Provider shall remain solely
responsible to the other parties to the Operative Agreements for the performance
of such obligations, (3) the Primary 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 Primary Liquidity Provider in
connection with the Advances and the Primary Liquidity Provider's rights and
obligations under the Operative Agreements, (4) the Primary 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 Primary 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 Primary Liquidity Provider.
The Primary 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 any information relating to the Operative
Agreements or to the parties thereto furnished to the Primary Liquidity Provider
thereunder or in connection therewith and permitted to be disclosed by the
Primary 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
Primary Liquidity Provider may assign and pledge all or any portion of the
Advances owing to it to any Federal Reserve Bank or the United States Treasury
as collateral security pursuant to Regulation A of the Board of Governors of the
Federal Reserve System and any Operating Circular issued by such Federal Reserve
Bank, provided that any payment in respect of such assigned Advances made by the
Borrower to the Primary Liquidity Provider in accordance with the terms of this
Agreement shall satisfy the Borrower's obligations hereunder in respect of such
assigned Advance to the extent of such payment. No such assignment shall release
