default that would not result in a Material Adverse Change to American), or
result in the creation of any Lien (other than as permitted under the related
Indenture) upon the Aircraft under, any indenture, mortgage, chattel mortgage,
deed of trust, conditional sales contract, lease, loan or other material
agreement, instrument or document to which American is a party or by which it or
any of its properties is bound.

                  (d) Approvals. The execution and delivery by American of the
Operative Agreements to which it is a party and the Underwriting Agreement as of
such date, the performance by American of its respective obligations thereunder
and the consummation by American of the Transactions contemplated thereby do not
and will not require the consent or approval of, or the giving of notice to, or
the registration with, or the recording or filing of any documents with, or the
taking of any other action in respect of, (a) any trustee or other creditor of
American, and (b) any Government Entity, other than (w) the filings or
recordings of the FAA Filed Documents and the Financing Statements (and
continuation statements periodically), (x) filings, recordings, notices or other
ministerial actions pursuant to any routine recording, contractual or regulatory
requirements applicable to it, (y) filings, recordings, notices or other actions
contemplated by the Operative Agreements in connection with the leasing or

                                      -7-

<PAGE>

reregistration of the Aircraft, and (z) filings, recordings, notices or other
actions relating to the Securities Act, the Trust Indenture Act or state
securities laws.

                  (e) Valid and Binding Agreements. The Operative Agreements and
the Underwriting Agreement executed and delivered by American on or prior to
such date have been duly executed and delivered by American and, assuming the
due authorization, execution and delivery thereof by the other party or parties
thereto, constitute the legal, valid and binding obligations of American and are
enforceable against American in accordance with the respective terms thereof,
except as such enforceability may be limited by bankruptcy, insolvency,
reorganization, receivership, moratorium and other similar laws affecting the
rights of creditors generally and general principles of equity, whether
considered in a proceeding at law or in equity and subject to principles of
public policy limiting the right to enforce the indemnification provisions
contained herein, insofar as such provisions relate to indemnification for
liabilities arising under federal securities laws.

                  (f) Representations and Warranties. The representations and
warranties of American contained in the Operative Agreements are true and
correct in all material respects.

                  (g) Litigation. Except as set forth in the Prospectus
Supplement, the most recent Annual Report on Form 10-K, as amended, of American
filed with the SEC on or prior to the Closing Date, or in any Quarterly Report
on Form 10-Q or Current Report on Form 8-K filed by American with the SEC
subsequent to such Form 10-K, no action, claim or proceeding is now pending or,
to the actual knowledge of American, threatened against American before any
court, governmental body, arbitration board, tribunal or administrative agency,
which would reasonably be expected to result in a Material Adverse Change to
American.

                  (h) Financial Condition. (i) The audited consolidated balance
sheet of American as of December 31, 2002 included in American's Annual Report
for the fiscal year ending December 31, 2002 on Form 10-K, as amended, filed by
American with the SEC, and the related consolidated statements of operations and
cash flows for the fiscal year then ended, and (ii) the unaudited consolidated
financial statements of American as of March 31, 2003 and for the period ending
March 31, 2003 included in the Quarterly Report on Form 10-Q of American have
each been prepared in conformity with GAAP and present fairly in all material
respects the consolidated financial condition of American and its consolidated
subsidiaries as of such dates and their consolidated results of operations and
cash flows for such periods. Since March 31, 2003, there has been no Material
Adverse Change of American, except as disclosed in the Prospectus Supplement,
the foregoing SEC filings or any Current Report on Form 8-K filed by American
with the SEC since March 31, 2003.

                  (i)      Registration and Recordation. The representation and
warranty of American set forth in Section 4.01(e) of each Participation
Agreement is true and correct.

                  (j)      No Default. No event exists that, in respect of any
Aircraft, constitutes an Indenture Event of Default.

                  (k)      No Event of Loss. No Event of Loss has occurred with
respect to any Airframe or any Engine which is Collateral under any Indenture
executed on the date hereof and,

                                      -8-

<PAGE>

to the actual knowledge of American, no circumstance, condition, act or event
has occurred that, with the giving of notice or lapse of time or both gives rise
to or constitutes an Event of Loss with respect to such Airframe or any such
Engine.

                  (l)      Compliance with Laws.

                           (a)      American is a Citizen of the United States
                  and a U.S. Air Carrier.

                           (b)      American holds all licenses, permits and
                  franchises from the appropriate Government Entities necessary
                  to authorize American to lawfully engage in air transportation
                  and to carry on scheduled commercial passenger service as
                  currently conducted, except where the failure to so hold any
                  such license, permit or franchise would not give rise to a
                  Material Adverse Change to American.

                           (c)      American is not an "investment company" or a
                  company controlled by an "investment company" within the
                  meaning of the Investment Company Act.

                  (m) Securities Laws. Neither American nor any Person
authorized to act on its behalf has directly or indirectly offered any
beneficial interest or Security relating to the ownership of the Aircraft, or
any of the Equipment Notes or any other interest in or security under any
Indenture, for sale, to, or solicited any offer to acquire any such interest or
security from, or has sold any such interest or security to, any Person in
violation of the Securities Act.

                  (n) Offering Document. Except for the Policy Provider
Information and the Underwriter Information, the Offering Document on the Offer
Date, and as of the Closing Date, neither contained or will contain any untrue
statement of a material fact nor omitted or will omit to state a material fact
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading.

                  (o) Section 1110. The Loan Trustee under each Indenture will
be entitled to the benefits of Section 1110 (as in effect on the Closing Date)
with respect to the Aircraft subject to such Indenture in the event of a case
under Chapter 11 of the Bankruptcy Code in which American is a debtor.

                  (p) Class G Certificates. Neither American nor any American
Entity owns or beneficially holds, directly or indirectly on the Closing Date
any Class G Certificates or any interest therein.

                  (q) Licenses. American holds all licenses, permits and
franchises from the appropriate government entities necessary to authorize
American to lawfully engage in air transportation and to carry on scheduled
commercial passenger service as currently conducted, except where the failure to
so hold any such license, permit or franchise would not give rise to a material
adverse change to American.

                  SECTION 2.02 Covenants of American. American covenants and
agrees with the Policy Provider as follows:

                                      -9-

<PAGE>

                  (a) So long as the Class G Certificates are outstanding,
neither American nor any of its Affiliates (i) will issue or permit to be
outstanding, directly or indirectly, on or after the Closing Date, any debt
(other than the Series G Equipment Notes) in respect of any Aircraft, including
in connection with a Refunding, in an aggregate amount in excess of 50% of the
Pool Balance of the Class G Certificates then outstanding (provided that any
reduction in the Pool Balance of the Class G Certificates in connection with a
prepayment of any Series G Equipment Notes pursuant to Sections 2.10(b) and
2.10(e) of any Indenture shall be deemed added to the Pool Balance of the Class
G Certificates for the purposes of such calculation), and (ii) will issue or
cause to be issued, directly or indirectly, any debt subordinate to the Series G
Equipment Notes in respect of any Aircraft, including in connection with a
Refunding, to any Person or entity other than American or any of its Affiliates
until the earlier to occur of (A) three years after the Closing Date and (B) the
date on which the corporate ratings assigned to American are at least BBB+ by
S&P and Baa1 by Moody's. American will not redeem, and will not permit the
redemption of, any Equipment Notes in connection with any Refunding pursuant to
Section 2.11(b) of any Indenture if (i) the conditions set forth in the
preceding sentence have not been satisfied, (ii) immediately prior to such
Refunding, any amounts are due to the Policy Provider in respect of Policy
Drawings, Policy Provider Interest Amounts, or amounts due under the Policy Fee
Letter, or (iii) immediately after giving effect to such Refunding, a Payment
Default (as defined in any Indenture) would exist under any Indenture or any
Related Indenture (as defined in any Indenture). So long as American or any of
its Affiliates owns, or beneficially holds, directly or indirectly, any Class C
Certificates or any interest therein, there shall be no Class C Liquidity
Facility in respect of the Class C Certificates. So long as American or any of
its Affiliates owns, or beneficially holds, directly or indirectly, any Class D
Certificates or any interest therein, there shall be no liquidity facility in
respect of the Class D Certificates.

                  (b) In the event that American does not maintain all-risk
aircraft hull insurance covering any Aircraft or all-risk coverage with respect
to any Engines (as defined in the related Indenture) or Parts (as defined in the
related Indenture) while removed from an Aircraft (including, without
limitation, war risk insurance) as required by Section 7.06(b) of the related
Indenture (the "Specified Insurance"), the Policy Provider is entitled, at its
own expense and without any reimbursement from American (including, without
limitation, pursuant hereto and the Policy Fee Letter or pursuant to any
Participation Agreement) to obtain such Specified Insurance for its own benefit.

                  (c) American agrees that if the Class G Liquidity Provider is
in default of any payment obligation of the Class G Liquidity Provider under the
Class G Liquidity Facility, American shall, with notice to the Policy Provider
and at its own expense, use commercially reasonable efforts to arrange for a
Replacement Class G Liquidity Facility to replace the Class G Liquidity
Facility; provided, that if the Class G Liquidity Provider in default of any
payment obligation is not replaced by American on or before the date of such
default, then American shall pay to the Policy Provider fees and expenses in the
same amounts and in the same manner that had been payable to the defaulted Class
G Liquidity Provider in connection with its commitment under its Class G
Liquidity Facility (the "Liquidity Fees and Expenses"). American's obligation to
pay the Liquidity Fees and Expenses to the Policy Provider shall terminate on
the earlier of (i) date that the Policy Provider's obligations terminate under
the Policy, and (ii) the date of the issuance of a Replacement Class G Liquidity
Facility.

                                      -10-

<PAGE>

                  (d) American agrees that American will use, and will cause
each other American Entity to use, reasonable best efforts to insure that no
American Entity will own, or beneficially hold, directly or indirectly, any
Class G Certificates or any interest therein. In the event that an American
Entity acquires an interest in any Class G Certificate, American agrees to
immediately pledge, and agrees to cause such other American Entity to
immediately pledge, such interest to the Policy Provider pursuant to the terms
of the Pledge Agreement.

                  (e) Neither the American nor any person authorized to act on
its behalf will directly or indirectly offer any beneficial interest or security
relating to the ownership of the Aircraft or any interest in any of the
Equipment Notes or any other interest in or security under any Indenture, for
sale to, or solicit any offer to acquire any such interest or security from, or
sell any such interest or security to, any person in violation of the Securities
Act or applicable state or foreign securities laws.

                  SECTION 2.03 Representations, Warranties and Covenants of U.S.
Bank, Class G Trustee and Subordination Agent. Each of U.S. Bank, Class G
Trustee and Subordination Agent represents, warrants and covenants to American
and the Policy Provider that it shall perform and observe, in all material
respects, all of its respective covenants, obligations and agreements in any
Operative Agreement to which it is a party to be observed or performed by it.

                  SECTION 2.04 Representations, Warranties and Covenants of the
Policy Provider. The Policy Provider represents, warrants and covenants to
American and the Subordination Agent as follows:

                  (a) Organization and Licensing. The Policy Provider is duly
organized, validly existing and in good standing as a Wisconsin-domiciled stock
insurance company, duly qualified to conduct an insurance business in every
jurisdiction where qualification may be necessary to accomplish the
Transactions.

                  (b) Corporate Power. The Policy Provider has the corporate
power and authority to issue the Policy, to execute and deliver this Insurance
Agreement and the other Operative Agreements to which it is a party and to
perform all of its obligations hereunder and thereunder.

                  (c) Authorization; Approvals. The Policy Provider has duly
authorized, executed and delivered this Insurance Agreement, the Intercreditor
Agreement, the Indemnification Agreement, the Policy Fee Letter and the Ambac
Supplemental Agreements. All proceedings legally required for the issuance and
execution, delivery and performance of the Policy and the execution, delivery
and performance of this Insurance Agreement have been taken and all licenses,
orders, consents or other authorizations or approvals of any Government Entity
legally required for the enforceability of the Policy have been obtained; any
proceedings not taken and any licenses, authorizations or approvals not obtained
are not material to the enforceability of the Policy.

                  (d) Enforceability. This Insurance Agreement, the
Intercreditor Agreement, the Policy Fee Letter, the Indemnification Agreement,
the Ambac Supplemental Agreements and the Policy (the "Ambac Documents") each
constitute a legal, valid and binding obligation of the Policy Provider,
enforceable in accordance with its terms, subject to bankruptcy, insolvency,

                                      -11-

<PAGE>

reorganization, receivership, moratorium and other similar laws affecting
creditors' rights generally and to general principles of equity and subject to
principles of public policy limiting the right to enforce the indemnification
provisions contained herein, insofar as such provisions relate to
indemnification for liabilities arising under federal securities laws.

                  (e) No Conflicts. The execution and delivery by the Policy
Provider of the Ambac Documents does not, and the performance by the Policy
Provider of its obligations under such documents will not, conflict with or
result in a breach of any of the terms, conditions or provisions of the
certificate of incorporation or by-laws of the Policy Provider, or any
restriction contained in any contract, agreement or instrument to which the
Policy Provider is a party or by which it is bound or violate any judgement,
order or decree applicable to the Policy Provider of any governmental or
regulatory body, administrative agency, court or arbitrator having jurisdiction
over the Policy Provider or constitute a default under any of the foregoing
which would materially and adversely affect its ability to perform its
obligations under the Ambac Documents.

                  (f) Financial Information. (i) The consolidated financial
statements of the Policy Provider and its subsidiaries as of December 31, 2002
and December 31, 2001, and for each of the years in the three-year period ended
December 31, 2002, included in the Annual Report on Form 10-K of Ambac Financial
Group, Inc. (which was filed with the SEC on March 28, 2003, SEC File Number
001-10777), (ii) the unaudited consolidated financial statements of the Policy
Provider and its subsidiaries as of March 31, 2003 and for the periods ending
March 31, 2003 and March 31, 2002 included in the Quarterly Report on Form 10-Q
of Ambac Financial Group, Inc. for the period ended March 31, 2003 (which was
filed with the SEC on May 15, 2003), and (iii) the Current Reports on Form 8-K
filed with the SEC on January 24, 2003, February 28, 2003, March 4, 2003, March
20, 2003, March 26, 2003, March 31, 2003 and April 21, 2003, as such reports
relate to the Policy Provider, each fairly presents in all material respects the
financial condition of the Policy Provider as of such dates and for the periods
covered by such statements in accordance with accounting principles generally
accepted in the United States of America. Since March 31, 2003, there has been
no change in the financial condition or operations of the Policy Provider that
would materially and adversely affect its ability to perform its obligations
under the Policy, except as disclosed in the Prospectus Supplement, the
foregoing SEC filings or any Current Report on Form 8-K filed with the SEC since
March 31, 2003.

                  (g) Policy Provider Information. The Policy Provider
Information is limited and does not purport to provide the scope of disclosure
required to be included in a prospectus with respect to a registrant in
connection with the offer and sale of securities of such registrant registered
under the Securities Act. Within such limited scope of disclosure, however, as
of the Offer Date, the Policy Provider Information did not, and as of the
Closing Date, the Policy Provider Information does not, contain an untrue
statement of a material fact or omit to state a material fact necessary to make
the statements therein, in light of the circumstances in which they were made,
not misleading.

                  (h) No Litigation. There are no actions, suits, proceedings or
investigations pending or, to the best of the Policy Provider's knowledge,
threatened against it at law or in equity or before or by any court,
governmental agency, board or commission or any arbitrator

                                      -12-

<PAGE>

which, if decided adversely, would materially and adversely affect its ability
to perform its obligations under the Operative Agreements to which it is a
party.

                  (i) Compliance with Law, Etc. No practice, procedure or policy
employed, or proposed to be employed, by the Policy Provider in the conduct of
its business violates any law, regulation, judgment, agreement, order or decree
applicable to the Policy Provider that, if enforced, could result in a Material
Adverse Change with respect to the Policy Provider.

                  (j) Securities Act. The issuance of the Policy as described in
the Prospectus Supplement is exempt from registration under the Securities Act
pursuant to Section 3(a)(8) thereof.

         other circumstances relating to the Class G Certificates or provision
         being made for payment of the Class G Certificates prior to maturity;

                  SECTION 3.03 Reimbursement Obligation.

                  (a) As and when due in accordance with and from the funds
specified in Sections 2.04(b), 3.02 and 3.03 of the Intercreditor Agreement, the
Policy Provider shall be entitled to reimbursement for any payment made by the
Policy Provider under the Policy to the Subordination Agent or to the Class G
Liquidity Provider under Section 2.06(c) or 3.07(c) of the Intercreditor
Agreement (the "Policy Payments"), which reimbursement shall be due and payable
on the date provided in such Sections, in an amount equal to the amount to be so
paid and all amounts previously paid that remain unreimbursed. In addition, to
the extent that any such payment by the Policy Provider shall have been made as
a result of a default by the Class G Liquidity Provider in its obligation to
make an Advance, as provided in the Intercreditor Agreement, the Policy Provider
shall be entitled to the payment of interest on such amounts to the extent, at
the time and in the priority that the Class G Liquidity Provider would have been
paid pursuant to Sections 2.04(b), 3.02 and 3.03 of the Intercreditor Agreement
had the Class G Liquidity Provider made such Advance.

                  (b) After the maturity date of the Series G Equipment Notes
and following the sale or other disposition of the Collateral or the Series G
Equipment Notes under all defaulted Indentures (the "Reimbursement Date"), and
so long as there are no Liquidity Obligations owing to the Class G Liquidity
Provider, if the Policy Provider has not been reimbursed in full for all Policy
Payments under the Intercreditor Agreement, American agrees to reimburse the
Policy Provider immediately, upon demand, to the extent of such Policy Payments,
less any amount in respect of such Policy Payments paid to and received by the
Policy Provider as a distribution to it under the Intercreditor Agreement (the
"Reimbursable Amount"); provided, that, notwithstanding the foregoing, if at any
time prior to the Reimbursement Date there are no Liquidity Obligations
outstanding, the Policy Provider shall be entitled to reimbursement by American
immediately upon demand of any Reimbursable Amount; provided, further that,
notwithstanding the foregoing, American's obligations under the other Operative
Agreements and the Policy Provider's rights to payments thereunder shall not be
affected or reduced by this Section 3.03, except to the extent that American
shall not be required to make any payment to the Policy Provider under this
Section 3.03(b) that has already been received by the Policy Provider pursuant
to the Intercreditor Agreement.

                  (c) American agrees to pay to the Policy Provider any and all
charges, fees, costs and expenses that the Policy Provider may reasonably pay or
incur, including actual and reasonable attorneys' and accountants' fees and
expenses (without duplication of amounts paid to the Policy Provider in respect
of the Operative Agreements), in connection with (i) the preservation (in
connection with the occurrence of an Indenture Event of Default), enforcement or
defense of any rights in respect of this Insurance Agreement, including
defending, monitoring or participating in any litigation or proceeding,
including any bankruptcy proceeding, and (ii) any amendment, modification,
waiver, consent or other action requested by or agreed to by American with
respect to, or related to, any Operative Agreements or to any form document

                                      -16-

<PAGE>

attached to any Operative Agreement as an exhibit, schedule or annex thereto,
whether or not executed or completed. Provided that five (5) Business Days'
prior written notice of the intended payment or incurrence shall have been given
to American by the Policy Provider, such reimbursement shall be due on the dates
on which such charges, fees, costs or expenses are paid or incurred by the
Policy Provider.

                  (d) In the event that any payment of any kind is made under
the Policy in respect of Class G Certificates owned or beneficially held,
directly or indirectly, by American or any American Entity, American agrees to
immediately refund such payment directly to the Policy Provider.

                  SECTION 3.04 Indemnification. American agrees that the Policy
Provider is hereby entitled to the full benefit of the indemnity contained in
each Policy Provider Indemnity and Inspection Agreement as if such provisions
were set forth in full herein and as if the "Operative Documents" referred to
therein include this Insurance Agreement. The Policy Provider agrees to comply
with all of its obligations as an Indemnitee under Section 1.1(f) of each Policy
Provider Indemnity and Inspection Agreement.

                  SECTION 3.05 Procedure for Payment of Fees and Premiums. All
payments to be made to the Policy Provider under this Insurance Agreement shall
be made to the Policy Provider in lawful currency of the United States of
America in immediately available funds on the date when due to such account as
the Policy Provider shall direct by written notice given at least ten calendar
days prior to such date to American. In the event that the date of any payment
to the Policy Provider or the expiration of any time period hereunder occurs on
a day that is not a Business Day, then such payment shall be made, or such
expiration of time period shall occur, on the next succeeding Business Day with
the same force and effect as if such payment was made or time period expired on
the scheduled date of payment or expiration date, as applicable.

                  SECTION 3.06 Late Payments. If American fails to pay the
Premium or any other amounts owing to the Policy Provider under this Insurance
Agreement or the Policy Fee Letter (including without limitation any Policy
Drawings, Premiums, indemnities, fees, costs and expenses) when due, interest on
such amount shall be assessed against, and due and payable by, American at the
Late Payment Rate from the date such amount was due until the date such amount
is paid; provided that, notwithstanding the foregoing, American's obligations
under the other Operative Agreements and the Policy Provider's rights to
payments thereunder shall not be affected or reduced by this Section 3.06,
except to the extent that American shall not be required to make any payment to
the Policy Provider under this Section 3.06 that has already been received by
the Policy Provider pursuant to the Intercreditor Agreement and no payment shall
be required to be made to the Policy Provider under the Intercreditor Agreement
(and no claim shall be made by the Policy Provider under the Intercreditor
Agreement) to the extent such amount has been received under this Agreement. For
the purposes of calculating late payments on Policy Payments, interest shall be
deemed to commence to accrue on the date that the Policy Provider made such
Policy Payment.

                  SECTION 3.07 Deductions. All payments made to the Policy
Provider by American in respect of this Article III shall be made without any
deduction or withholding for or on account of any tax, levy, impost, duty,
charge, assessment or fee of any nature (any of the

                                      -17-

<PAGE>

foregoing an "Additional Tax") unless such deduction or withholding is required
by any applicable law, as modified by the practice of any relevant governmental
revenue authority, then in effect. If a payor is so required to deduct or
withhold any Additional Tax, then such payor shall (a) promptly notify the
Policy Provider of such requirement, (b) pay to the Policy Provider, in addition
to the amount to which the Policy Provider is otherwise entitled, such
additional amount as is necessary to ensure that the net amount actually
received by the Policy Provider (free and clear of taxes, whether assessed
against the payor or the Policy Provider) will equal the full amount the Policy
Provider would have received had no such deduction or withholding been required,
provided that such an additional amount shall be payable only if such Additional
Tax would not have arisen but for a present or former connection between the
jurisdiction of the government or taxation authority imposing such Additional
Tax and the payor (or an Affiliate of such payor), and (c) pay to the relevant
authorities the full amount required to be deducted or withheld (including the
full amount required to be deducted or withheld from any additional amount, if
any, paid to the Policy Provider pursuant to foregoing clause (b)); provided,
that no additional amounts shall be required to be paid to the Policy Provider
hereunder in respect of Additional Taxes to the extent such Additional Taxes
would not have been imposed but for (i) the fact that the Policy Provider is not
the beneficial owner of the payment or that the Policy Provider (or any
transferee of any rights or interests thereof) ceases to be (or is not) a
"United States person" within the meaning of section 7701(a)(30) of the Internal
Revenue Code of 1986, as amended, (ii) any present or former connection between
the jurisdiction of the government or taxing authority imposing such Additional
Taxes and the Policy Provider, or (iii) the failure of the Policy Provider, as
soon as practicable after the payor's written request therefor, to complete,
execute and provide to or as directed by the payor any form of documentation
that may be required or reasonably requested by the payor in order to allow the
payor to make payments under this Insurance Agreement without deduction or
withholding for or on account of any Additional Taxes or with such deduction or
withholding at a reduced rate (so long as, in the sole discretion of the Policy
Provider, the completion, execution or submission of such form or document would
not adversely affect the legal or commercial position of the Policy Provider).

                                   ARTICLE IV

                               FURTHER AGREEMENTS

                  SECTION 4.01 Effective Date; Term of the Insurance Agreement.
This Insurance Agreement shall take effect on the Closing Date and shall remain
in effect until the later of (a) such time as the Policy Provider is no longer
subject to a claim under the Policy and the Policy shall have been surrendered
to the Policy Provider for cancellation, and (b) all amounts payable to the
Policy Provider by American or the Subordination Agent hereunder or from any
other source hereunder or under the Operative Agreements and all amounts payable
under the Class G Certificates have been paid in full; provided, that the
provisions of Section 3.04 hereof shall survive any termination of this
Insurance Agreement.

                  SECTION 4.02 Further Assurances and Corrective Instruments.

                  (a) Except as otherwise provided in Article VIII of the
Intercreditor Agreement, neither American nor the Subordination Agent shall (i)
agree to any amendment or modification to any of the Operative Agreements to
which either of them is a party, which amendment or

                                      -18-

<PAGE>

modification would have an adverse effect on the rights or remedies of the
Policy Provider, or (ii) grant any waiver of rights in respect of any of the
Operative Agreements to which either of them is a party, without the prior
written consent of the Policy Provider so long as the Policy Provider is the
Controlling Party and any such waiver without prior written consent of the
Policy Provider shall be null and void and of no force or effect.

                  (b) To the extent permitted by law, each of American, the
Policy Provider and the Subordination Agent agrees that it will, from time to
time, execute, acknowledge and deliver, or cause to be executed, acknowledged
and delivered, such supplements hereto and such further instruments as American,
the Policy Provider or the Subordination Agent may reasonably request and as may
be required to effectuate the intention of or facilitate the performance of this
Insurance Agreement.

                  SECTION 4.03 Obligations Absolute.

                  (a) The obligations of American hereunder and under the other
Operative Agreements shall be absolute and unconditional and shall be paid or
performed strictly in accordance with this Insurance Agreement and the other
Operative Agreements under all circumstances irrespective of:

                  (i)      any lack of validity or enforceability of, or any
         amendment or other modifications of, or waiver, with respect to any of
         the Operative Agreements (other than the Policy) or the Certificates;

                  (ii)     any exchange or release of any other obligations
         hereunder;

                  (iii)    the existence of any claim, setoff, defense,
         reduction, abatement or other right that any Person may have at any
         time against the Policy Provider or any other Person;

                  (iv)     any document presented in connection with the Policy
         proving to be forged, fraudulent, invalid or insufficient in any
         respect or any statement therein being untrue or inaccurate in any
         respect;

                  (v)      any payment by the Policy Provider under the Policy
         against presentation of a certificate or other document that does not
         strictly comply with the terms of the Policy;

                  (vi)     any failure of American to receive the proceeds from
         the sale of the Certificates; and

                  (vii)    any other circumstances, other than payment in full,
         that might otherwise constitute a defense available to, or discharge
         of, any Person in respect of any Operative Agreements.

                  (b) Each of the parties hereto renounces the right to assert
as a defense to the performance of its obligations herein each of the following:
(i) to the extent permitted by law, any and all redemption and exemption rights
and the benefit of all valuation and appraisement

                                      -19-

<PAGE>

privileges against the indebtedness and obligations evidenced by any Operative
Agreements or by any extension or renewal thereof; (ii) presentment and demand
for payment, notices of nonpayment and of dishonor, protest of dishonor and
notice of protest; (iii) all notices in connection with the delivery and
acceptance hereof and all other notices in connection with the performance,
default or enforcement of any payment hereunder, except as required by the
Operative Agreements; and (iv) all rights of abatement, diminution, postponement
or deduction, and all rights of setoff or recoupment arising out of any breach
under any of the Operative Agreements, by any party thereto or any beneficiary
thereof, or out of any obligation at any time owing to American.

                  (c) American (i) agrees that any consent, waiver or
forbearance hereunder or in the other Operative Agreements with respect to an
event shall operate only for such event and not for any subsequent event; (ii)
consents to any and all extensions of time that may be granted to American by
the Policy Provider with respect to any payment hereunder or other provisions
hereof; and (iii) consents to the addition of any and all other makers,
endorsers, guarantors and other obligors for any payment hereunder, and to the
acceptance of any and all other security for any payment hereunder, and agrees
that the addition of any such obligors or security shall not affect the
liability of American for any payment hereunder.

                  (d) No failure by the Policy Provider to exercise, and no
delay by the Policy Provider in exercising, any right hereunder or under the
Operative Agreements shall operate as a waiver thereof. The exercise by the
Policy Provider of any right hereunder shall not preclude the exercise of any
other right, and the remedies provided herein to the Policy Provider are
declared in every case to be cumulative and not exclusive of any remedies
provided by law or equity.

                  (e) Nothing herein shall be construed as prohibiting any party
hereto from pursuing any rights or remedies it may have against any Person in a
separate legal proceeding.

                  SECTION 4.04 Assignments; Reinsurance; Third-Party Rights.

                  (a) This Insurance Agreement shall be a continuing obligation
of the parties hereto and shall be binding upon and inure to the benefit of the
parties hereto and their respective successors and permitted assigns. The
Subordination Agent, except as provided in Section 7.01 of the Intercreditor
Agreement, and American, except for any transaction expressly permitted by
Section 5.02 of the Basic Agreement, may not assign their respective rights
under this Insurance Agreement, or delegate any of their duties hereunder,
without the prior written consent of the other parties hereto. The Policy
Provider, except as set forth in subsection (b) of this Section 4.04, may not
assign its rights under this Insurance Agreement or delegate any of its duties
hereunder without the prior written consent of the other parties hereto. Any
assignments made in violation of this Insurance Agreement shall be null and
void.

                  (b) The Policy Provider shall have the right to grant
participations in its rights under this Insurance Agreement and to enter into
contracts of reinsurance with respect to the Policy upon such terms and
conditions as the Policy Provider may in its discretion determine; provided,
that no such participation or reinsurance agreement or arrangement shall relieve
the Policy Provider of any of its obligations hereunder or under the Policy or
grant to any participant or reinsurer any rights hereunder or under any
Operative Agreement, and neither American nor

                                      -20-

<PAGE>

any other party to any Operative Agreement shall be required to pay the Policy
Provider hereunder or under any other Operative Agreement any amount greater
than it would have been required to pay had there been no such participation or
reinsurance.

                  (c) Except as provided herein with respect to participants and
reinsurers, nothing in this Insurance Agreement shall confer any right, remedy
or claim, express or implied, upon any Person, including, particularly, any
Holder, other than upon the Policy Provider against American, or upon American
against the Policy Provider (either directly or as the Controlling Party), and
all the terms, covenants, conditions, promises and agreements contained herein
shall be for the sole and exclusive benefit of the parties hereto and their
successors and permitted assigns. None of the Subordination Agent, the Class G
Liquidity Provider, the Trustee or any Holder shall have any right to payment
from the Premium paid or payable hereunder or from any amounts paid by American
pursuant to Section 3.02, 3.03, 3.04, 3.05 or 3.06 hereof.

                  SECTION 4.05 Liability of the Policy Provider. Neither the
Policy Provider nor any of its officers, directors or employees shall be liable
or responsible for: (i) the use that may be made of the Policy by the
Subordination Agent or for any acts or omissions of the Subordination Agent in
connection therewith; or (ii) the validity, sufficiency, accuracy or genuineness
of documents delivered to the Policy Provider in connection with any claim under
the Policy, or of any signatures thereon, even if such documents or signatures
should in fact prove to be in any or all respects invalid, insufficient,
fraudulent or forged (unless the Policy Provider shall have actual knowledge
thereof). In furtherance and not in limitation of the foregoing, the Policy
Provider may accept documents that appear on their face to be in order, without
responsibility for further investigation.

                  SECTION 4.06 No Duplication of Payments. Any payments made
hereunder to the Policy Provider are to be without duplication of any payments
received by the Policy Provider under the Intercreditor Agreement and, to the
extent that the Policy Provider has received, pursuant to the Intercreditor
Agreement, payment of any amounts due or owing hereunder, such payment shall not
be sought by the Policy Provider pursuant to the terms hereof. Any payments made
under the Intercreditor Agreement are to be without duplication of any payments
received by the Policy Provider hereunder and, to the extent that the Policy
Provider has received hereunder payment of any amounts due or owing under the
Intercreditor Agreement, such payment shall not be sought by the Policy Provider
pursuant to the terms of the Intercreditor Agreement.

                                   ARTICLE V

                                  MISCELLANEOUS

amended, modified, supplemented or terminated only by written instrument or
written instruments signed by the parties hereto; provided that if such
amendment, modification, supplement or termination would have a material adverse
effect on the interests of the Subordination Agent, a Pass Through Trustee or
any Class G Certificateholder, Ratings Confirmation shall also be obtained prior
to such amendment, modification, supplement or termination being effective.
American agrees to provide a copy of any amendment to this Insurance Agreement
promptly to the Subordination

                  SECTION 5.03 Severability. In the event that any provision of

competent jurisdiction, the parties hereto agree that such holding shall not
invalidate or render unenforceable any other provision hereof. The parties

                  (a) The parties hereto hereby irrevocably submit to the
non-exclusive jurisdiction of the United States District Court for the Southern

New York located in the City and County of New York, and any appellate court
from any thereof, in any action, suit or proceeding brought against it or in

or in any other manner provided by law. To the extent permitted by applicable
law, the parties hereto hereby waive and agree not to assert by way of motion,
as a defense or otherwise in any such suit, action or proceeding, any claim that
it is not personally subject to the jurisdiction of such courts, that the suit,
action or proceeding is brought in an inconvenient forum, that the venue of the
suit, action or proceeding is improper or that the related documents or the
subject matter thereof may not be litigated in or by such courts.

                  (b) To the extent permitted by applicable law, the parties

address may be changed by such party by written notice to the other parties
hereto.

against any other party or its properties in the courts of any jurisdiction.

relating to the Policy Provider contained in any Offering Document, which
disclosure modifies, alters, changes, amends or supplements the disclosure
relating to the Policy Provider provided by the Policy Provider for use in the

consent. In the event that the consent of the Policy Provider is required under,
or the Policy Provider, as Controlling Party or otherwise, gives direction to
the Loan Trustee, the Subordination Agent or the Pass Through Trustee pursuant
to, any Operative Agreement, the determination whether to grant or withhold such
consent or to give such direction shall be made by the Policy Provider in its
sole discretion without any implied duty towards any other Person.

has been induced to enter into the Operative Agreements to which it is a party
by, among other things, this waiver.

Operative Agreement or the Policy shall be had against, and no personal
liability shall attach to, any officer, employee, director, affiliate or
shareholder of any party hereto, as such, by the enforcement of any assessment
or by any legal or equitable proceeding, by virtue of any statute or otherwise
in respect of any of the Operative Agreements, the Certificates or the Policy,
it being expressly agreed and understood that each Operative Agreement is solely
an obligation of each party hereto, and that any and all personal liability,
either at common law or in equity, or by statute or constitution, of every such
officer, employee, director, affiliate or shareholder for breaches of any party
hereto of any obligations under any Operative Agreement is hereby expressly
waived as a condition of and in consideration for the execution and delivery of
this Insurance Agreement.

                  SECTION 5.11 Entire Agreement. This Insurance Agreement, the
Policy, the Policy Fee Letter and the other Operative Agreements set forth the
entire agreement between the parties with respect to the subject matter hereof

agreement or understanding that may have existed between the parties prior to

construed to vary or otherwise modify any terms of the Policy. No breach by any
party hereto of any representation, warranty, covenant, agreement or undertaking
contained herein shall in any way affect the obligations of the Policy Provider
under the Policy.

<PAGE>

                  (b)      Underwriter Information. All material provided by

Offering Document (as revised from time to time), insofar as such information

                  (c)      Compliance with Laws. Such Underwriter will comply in
all material respects with all legal requirements in connection with its offers
and sales of the Class G Certificates and will make such offers and sales in the
manner provided in the Offering Document.

                  (d)      Organization, Power, Enforceability. Such Underwriter
is duly organized, validly existing and in good standing in the jurisdiction of
its organization and has the corporate power and authority to execute and
deliver this Indemnification Agreement and to perform its obligations hereunder.
This Indemnification Agreement constitutes a legal, valid and binding obligation
of such Underwriter, enforceable in accordance with its terms, subject to
bankruptcy, insolvency, reorganization, moratorium, receivership and other
similar laws affecting creditors' rights generally and by general principles of
equity and subject to principles of public policy limiting the right to enforce

information contained in the last three sentences of the second paragraph, the
second and third sentences of the fourth paragraph, and the eighth paragraph, in
each case, under the heading "Underwriting" in the Prospectus Supplement (the
"Underwriter Information"), (i) the Offering Document, as of the date thereof,
neither contained any untrue statement of a material fact nor omitted to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and (ii) as of the date hereof, the Offering Document
did not, and on the Closing Date the Offering Document will not, contain any
untrue statement of a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading.

                  (b)      The Incorporated Documents heretofore filed were
filed in a timely manner and, when they were filed (or, if any amendment with
respect to any such document was filed, when such amendment was filed), complied
in all material respects with the requirements of the Exchange Act and did not
contain an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading.

                  (c)      As of the date hereof, its representations and
warranties contained in the Underwriting Agreement are true and correct in all
material respects.

                                       2

<PAGE>

                  (d)      The Company will not use any Offering Document in
connection with the offer and sale of the Class G Certificates unless the
information included in or incorporated into by reference in such Offering
Document under the caption "Description of the Policy Provider" (or a similar
caption making reference to the Policy Provider) has been furnished by the
Policy Provider for inclusion therein and has been approved by the Policy
Provider. Without limiting the foregoing, no disclosure relating to the Policy
Provider contained in any Offering Document, which disclosure modifies, alters,
changes, amends or supplements the Policy Provider Information, shall be made
without the Policy Provider's prior written consent.

                  Section 4. Representations, Warranties and Agreements of the
Policy Provider. The Policy Provider represents and warrants to, and agrees
with, American and each of the Underwriters as follows:

                  (a)      Organization and Licensing. The Policy Provider is a
Wisconsin domiciled stock insurance company which is licensed under the laws of
the State of Wisconsin and is duly qualified or licensed to conduct an insurance
business in each jurisdiction where qualification may be necessary to accomplish
the Transactions (as defined in the Policy Provider Agreement).

                  (b)      Corporate Power. The Policy Provider has the
corporate power and authority to issue the Policy and execute and deliver this
Indemnification Agreement, the Intercreditor Agreement and the Policy Provider
Agreement and to perform all of its obligations hereunder and thereunder.

                  (c)      Authorization; Approvals. The Policy Provider has
duly authorized, executed and delivered this Indemnification Agreement.
Proceedings legally required for the issuance of the Policy and the execution,
delivery and performance of this Indemnification Agreement, the Intercreditor
Agreement and the Policy Provider Agreement have been taken and licenses,
orders, consents or other authorizations or approvals of any governmental boards
or bodies legally required for the enforceability of the Policy, if any, have
been obtained; any proceedings not taken and any licenses, authorizations or
approvals not obtained are not material to the enforceability of the Policy.

                  (d)      Enforceability. The Policy, when issued, and each of
the Intercreditor Agreement and the Policy Provider Agreement, when executed,
will constitute, and this Indemnification Agreement constitutes, a legal, valid
and binding obligation of the Policy Provider, enforceable in accordance with
its terms, except as enforcement may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium, receivership and other similar laws
affecting creditors' rights generally and by general principles of equity and
subject to principles of public policy limiting the right to enforce the
indemnification provisions contained therein and herein insofar as such
provisions relate to indemnification for liabilities arising under federal
securities laws.

                  (e)      Financial Information. The financial statements of
the Policy Provider included in or incorporated by reference into the Prospectus
Supplement, fairly

                                       3

<PAGE>

present in all material respects the financial condition of the Policy Provider
as of the dates and for the periods covered by such statements in accordance
with generally accepted accounting principles consistently applied. Since March
31, 2003, there has been no material change in such financial condition of the
Policy Provider that would materially and adversely affect its ability to
perform its obligations under the Policy, this Indemnification Agreement or the
Intercreditor Agreement.

                  (f)      Policy Provider Information. The Policy Provider
Information is limited and does not purport to provide the scope of disclosure
required to be included in a prospectus with respect to a registrant in
connection with the offer and sale of securities of such registrant registered
under the Securities Act; subject to the foregoing, as of the date hereof, the
information included in or incorporated into by reference in the Prospectus
Supplement under the caption "Description of the Policy Provider" (the "Policy
Provider Information") does not contain an untrue statement of a material fact
or omit to state a material fact necessary to make the statements therein, in
light of the circumstances in which they were made, not misleading. The Policy
Provider consents to the inclusion in the Prospectus Supplement of the Policy
Provider Information. The Policy Provider will promptly inform American and the
Underwriters of any information which would cause the representation and
warranty of the Policy Provider set forth in the first sentence of this
subsection (f) not to be true and correct as of the Closing Date.

                  (g)      No Litigation. There are no actions, suits,
proceedings or investigations pending or, to the best of the Policy Provider's
knowledge, threatened against it at law or in equity or before or by any court,
governmental agency, board or commission or any arbitrator which, if decided
adversely, would materially and adversely affect its ability to perform its
obligations under the Policy, this Indemnification Agreement, the Intercreditor
Agreement or the Policy Provider Agreement.

                  (h)      Exemption from Registration. The Policy is exempt
from registration under the Securities Act.

                  Section 5. Indemnification and Contribution. (a) The Policy
Provider agrees to indemnify and hold harmless (i) each Underwriter, each of its
officers, directors, shareholders, employees, agents and each person, if any,
who controls such Underwriters within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act and (ii) American, each of its
officers, directors, shareholders, employees, agents and each person, if any,
who controls American within the meaning of either Section 15 of the Securities
Act or Section 20 of the Exchange Act, in each case from and against any and all
losses, claims, damages and liabilities (including, without limitation, any
legal or other expenses reasonably incurred by such indemnitee in connection
with defending or investigating any such action or claim) caused by any untrue
statement or alleged untrue statement of a material fact contained in the Policy
Provider Information, or caused by any omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, or a breach of any of the representations and
warranties of the Policy Provider contained in Section 4 hereof.

                                       4

<PAGE>

                  (b)      Each Underwriter agrees, severally and not jointly,
to indemnify and hold harmless the Policy Provider, each of its officers,
directors, shareholders, employees, agents and each person, if any, who controls
the Policy Provider within the meaning of either Section 15 of the Securities
Act or Section 20 of the Exchange Act from and against any and all losses,
claims, damages and liabilities (including, without limitation, any legal or
other expenses reasonably incurred by such indemnitee in connection with
defending or investigating any such action or claim) caused by any untrue
statement or alleged untrue statement of a material fact contained in the
information relating to such Underwriter contained in the Underwriter
Information, or a breach of any of the representations and warranties of such
Underwriter contained in Section 2 hereof.

                  (c)      Except for the Policy Provider Information and the
Underwriter Information, American agrees to indemnify and hold harmless the
Policy Provider, each of its officers, directors, shareholders, employees,
agents and each person, if any, who controls the Policy Provider within the
meaning of either Section 15 of the Securities Act or Section 20 of the Exchange
Act from and against any and all losses, claims, damages and liabilities
(including, without limitation, any legal or other expenses reasonably incurred
by such indemnitee in connection with defending or investigating any such action
or claim) caused by any untrue statement or alleged untrue statement of a
material fact contained in any Offering Document, or caused by any omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, or a breach of any
of the representations and warranties of American contained in Section 3 hereof.

                  (d)      In case any action or proceeding (including any
governmental investigation) shall be instituted involving any person in respect
of which indemnity may be sought pursuant to subsection (a), (b) or (c) of this
Section 5, such person (the "Indemnified Party") shall promptly notify the
person against whom such indemnity may be sought (the "Indemnifying Party") in
writing; provided, that the failure to notify the Indemnifying Party shall not
relieve the Indemnifying Party from any liability that it may have under this
Section 5 except to the extent that the Indemnifying Party has been materially
prejudiced (through the forfeiture of substantive rights or defenses) by such
failure; provided further, that the failure to notify the Indemnifying Party
shall not relieve it from any liability that it may have to an Indemnified Party
other than under this Section 5. An Indemnifying Party may participate at its
own expense in the defense of such action. If it so elects within a reasonable
time after receipt of such notice, an Indemnifying Party, jointly with any other
Indemnifying Parties receiving such notice, may, except as provided in the
immediately following sentence, assume the defense of such action, with counsel
reasonably satisfactory to the Indemnified Party to represent the Indemnified
Party and any others the Indemnifying Party may designate in such proceeding and
shall pay the fees and disbursements of such counsel related to such proceeding.
In any such proceeding, any Indemnified Party shall have the right to retain its
own counsel, but the fees and expenses of such counsel shall be at the expense
of such Indemnified Party unless (i) the Indemnifying Party and the Indemnified
Party shall have mutually agreed to the retention of such counsel, (ii) the
Indemnifying Party has failed within a reasonable time to assume defense of such
action or proceeding or retain counsel

                                       5

<PAGE>

reasonably satisfactory to the Indemnified Party, or (iii) the named parties to
any such proceeding (including any impleaded parties) include both the
Indemnifying Party and the Indemnified Party and representation of both parties
by the same counsel would be inappropriate due to actual or potential differing
interests between them or the Indemnified Party shall have been advised by
counsel that one or more legal defenses available to it may be different from or
in addition to those available to the Indemnifying Party. It is understood that
the Indemnifying Party shall not under subsection (a), (b) or (c) of this
Section 5, in respect of the legal expenses of any Indemnified Party in
connection with any proceeding, be liable for the fees and expenses of more than
one separate firm (in addition to any local counsel) for all such Indemnified
Parties and that all such fees and expenses shall be reimbursed as they are
incurred. The Indemnifying Party shall not be liable for any settlement of any
proceeding effected without its written consent, but if settled with such
consent or if there be a final judgment for the plaintiff, the Indemnifying
Party agrees to indemnify the Indemnified Party from and against any loss or
liability by reason of such settlement or judgment. No Indemnifying Party shall,
without the prior written consent of the Indemnified Party, effect any
settlement of any pending or threatened proceeding in respect of which any
Indemnified Party is or could have been a party and indemnity could have been
sought hereunder by such Indemnified Party, unless such settlement includes an
unconditional release of such Indemnified Party from all liability on claims
that are the subject matter of such proceeding.

                  (e)      To provide for just and equitable contribution if the
indemnification provided by the Indemnifying Party is determined to be
unavailable or insufficient to hold harmless any Indemnified Party (other than
due to application of this Section), each Indemnifying Party shall contribute to
the losses incurred by the Indemnified Party on the basis of the relative fault
of the Indemnifying Party, on the one hand, and the Indemnified Party, on the
other hand. The relative fault of each Indemnifying Party, on the one hand, and
each Indemnified Party, on the other, shall be determined by reference to, among
other things, (i) whether the breach of, or alleged breach of, any of its
representations and warranties set forth herein are within the control of the
Indemnifying Party or the Indemnified Party, (ii) whether any untrue or alleged
untrue statement of a material fact or omission or alleged omission to state a
material fact related to information supplied by the Indemnifying Party or the
Indemnified Party and (iii) the parties relative intent, knowledge, access to
information and opportunity to correct or prevent such statement, omission or
breach.

                  (f)      The indemnity and contribution provisions contained
in this Section 5 shall remain operative and in full force and effect regardless
of (i) any termination of this Indemnification Agreement, (ii) any due diligence
investigation or statement as to the results of any due diligence investigation
by or on behalf of (x) any Underwriter or any person controlling any Underwriter
(y) the Policy Provider, its officers or directors or any person controlling the
Policy Provider or (z) American, its officers or directors or any person
controlling American, and (iii) acceptance of and payment for any of the Class G
Certificates.
