FedEx for Delivery pursuant to this Agreement fewer than twelve (12) Firm
Aircraft, then on or before October 13, 1999 or such later date as the Parties
agree will be the Scheduled Delivery Date for the twelfth (12th) Firm Aircraft,
American will pay to FedEx $[* ] for each Firm Aircraft fewer than twelve
(12) that American delivers to FedEx. American will make such payment by a
wire transfer of immediately available funds.

Section 2.02. Put Options. (a) FedEx hereby grants to American
seven (7) options (the "Put Options" and each a "Put Option"), each of which
shall give American the right to sell one Aircraft to FedEx on each of the
Scheduled Delivery Dates set forth in the table in Section 2.02(c). Upon
American's exercise of each Put Option, FedEx shall purchase one Aircraft on
the terms and subject to the conditions set forth herein.

(b) A Put Option will be exercisable as to an Aircraft by American
giving to FedEx a Put Option Exercise on any date not later than the "Latest
Exercise Date" as set forth in Section 2.02(c).

(c) The latest date by which a Put Option may be exercised (each a
"Latest Exercise Date"), the latest date by which a Designation for a Scheduled
Delivery Date may be given, the Scheduled Delivery Dates for the Put Option
Aircraft and the Purchase Price of each Put Option Aircraft are as set forth in

(d) American and FedEx intend the exercise of the Put Options to be
sequential and consistent with the schedule set forth above. If American fails
to give FedEx a Put Option Exercise exercising a particular Put Option on or
before the Latest Exercise Date for such Put Option, that Put Option will
expire. If a Put Option expires, the remaining Put Options may be cancelled by
FedEx giving to

-11-
<PAGE> 18
American written notice of such cancellation on or before the earlier of (i)
the next following Latest Exercise Date set forth in Section 2.02(c) and (ii)
the seventh (7th) day next following the day on which FedEx receives a written
notice from American that FedEx has the right to cancel the remaining Put
Options. If FedEx fails to give American timely written notice of the
cancellation of the remaining, unexercised Put Options, the remaining,
unexercised Put Options will remain in full force and effect. The failure of
American to give to FedEx any notice that FedEx may cancel the remaining,
unexercised Put Options shall not be a breach, default or Event of Default
under the terms of this Agreement.

Section 2.03. Purchase Options. (a) If American intends to offer
any Put Option Aircraft not designated as a Firm Aircraft for sale to a third
party, FedEx shall have the right, but not the obligation, to purchase such Put
Option Aircraft from American on the terms and subject to the conditions set
forth in this Section 2.03 (the "Purchase Options" and each, a "Purchase
Option"). American shall give FedEx a Purchase Option Notice before American
makes an offer to sell any or all of the Put Option Aircraft to any third
party. FedEx may exercise the Purchase Options as to any or all of the Put
Option Aircraft stated in a Purchase Option Notice by giving American a
Purchase Option Exercise within fourteen (14) days after its receipt of the
Purchase Option Notice. The failure of FedEx to give American a Purchase
Option Exercise within [ * ] of its receipt of the Purchase
Option Notice will entitle American to sell the Put Option Aircraft to any
person or persons free of the Purchase Options, but such failure shall not be a
breach by FedEx of, or a default or an Event of Default under, the terms of
this Agreement. If FedEx does not exercise a Purchase Option as to a
particular Put Option Aircraft, (i) American may offer for sale and may sell
such Put Option Aircraft in such manner, at such time or times, for such price
or prices and on such other terms and subject to such conditions as American,
in its sole discretion, deems acceptable and (ii) American may nevertheless
exercise the remaining, unexpired Put Options in accordance with the terms and
subject to the conditions set forth in Section 2.02 without regard to any prior
Purchase Option Notice. American will provide a Designation with respect to
any Purchase Option Aircraft on or before the later to occur of (i) one year
prior to the Scheduled Delivery Date and (ii) the thirtieth (30th) day after
its receipt of a Purchase Option Exercise.

(b) The Purchase Price for any Purchase Option Aircraft which is
tendered by American for Delivery and which FedEx is obligated to purchase in
or before January, 1996, shall be $[ * ]. The Purchase Price for
any Purchase Option Aircraft which is tendered by American for Delivery and
which FedEx is obligated

-12-
<PAGE> 19
to purchase in any month thereafter shall be decreased by the amount of $[ *
] for each month after [ * ] to, but excluding, the month in which such
tender for Delivery occurs.

(c) The Scheduled Delivery Date of the Purchase Option Aircraft to
be sold to FedEx by American pursuant to FedEx's exercise of a Purchase Option
shall be the date or dates specified by American in the Purchase Option Notice
as the Scheduled Delivery Date or Scheduled Delivery Dates of the Purchase
Option Aircraft; provided, however, that no such Scheduled Delivery Date shall
be less than [ * ] after the date of the Purchase Option Notice
specifying such Scheduled Delivery Date.

(d) If American sells one or more Purchase Option Aircraft to
FedEx pursuant to FedEx's exercise of one or more Purchase Options or sells any
Put Option Aircraft as to which FedEx does not exercise a Purchase Option after
a Purchase Option Notice is given, the number of Put Options that American can
exercise shall be reduced by a number equal to the number of Purchase Option
Aircraft and/or Put Option Aircraft so sold. Any Put Options terminated by any
such reduction shall be terminated in the reverse order of the Scheduled
Delivery Dates to which the Put Options relate. The remaining Put Options
shall remain in full force and effect.

(e) If one or more Put Options expire or are terminated for any
reason, American may dispose of an equivalent number of Aircraft free of the
Purchase Options at any time thereafter and an equivalent number of Purchase
Options will terminate simultaneously and automatically. Upon such expiration
or termination, the terminated Purchase Options shall be without further force
and effect, provided, however, that any such termination of Purchase Options
shall not affect any prior exercise of any Purchase Option with respect to any
Aircraft. American shall have the right to sell or otherwise dispose of such
number of the Put Option Aircraft as to which Purchase Options are reduced free
of the Purchase Options and the provisions of this Agreement and may determine
which Put Option Aircraft are so free of the Purchase Options in its sole
discretion.

Section 2.04. Designation and Substitution of Airframes and
Engines. (a) American will designate an Airframe from among all the
Airframes as a Firm Aircraft, a Put Option Aircraft, or a Purchase Option
Aircraft for Delivery on a Scheduled Delivery Date in accordance with Section
2.01, Section 2.02 and Section 2.03, respectively, by giving FedEx a
Designation on or before the latest date for giving such Designation specified
in the applicable such section. Each Airframe to *Blank space contained
confidential information which has been filed separately with the Securities
and Exchange Commission pursuant to Rule 24b-2 under the Securities Exchange
Act of 1934.

-13-
<PAGE> 20
be designated by American to be part of a Firm Aircraft, a Put Option Aircraft
or a Purchase Option Aircraft to be delivered on any Scheduled Delivery Date as
to which a Designation is given will be chosen by American in its sole
discretion. American shall have the right as a result of operational
considerations to substitute a different Airframe for a previously designated
Airframe for delivery on a Scheduled Delivery Date by delivering a Change
Designation (i) on any date before the [ *
] prior to such Scheduled Delivery Date or (ii) if
such designation of a different Airframe for delivery on such Scheduled
Delivery Date would not cause a material delay in the conversion of such
different Airframe from a passenger configuration to a cargo
configuration, on any date before the [ * ] prior
to the original Scheduled Delivery Date, provided in either instance that,
within [ * ] after its receipt of FedEx's invoice setting
forth in detail the nature and amount of such costs, American reimburses FedEx
for any incremental engineering costs, incremental transition maintenance costs
and incremental modification costs incurred by FedEx solely as the result of
the substitution of the Airframe.

(b) No later than [ * ] prior to the Scheduled
Delivery Date for an Aircraft, American shall designate to FedEx the three
Engines to be conveyed to FedEx as part of such Aircraft to be delivered on
such Scheduled Delivery Date by giving FedEx a completed Engine Designation.
After designating such Engines, American will use its commercially reasonable
efforts to avoid substituting other Engines for such designated Engines, but
may do so upon written notice to FedEx, which notice shall be given by American
as soon as practicable after it determines to substitute Engines. Each Engine
to be designated by American to be a part of a Firm Aircraft, a Put Option
Aircraft or a Purchase Option Aircraft to be delivered on the various Scheduled
Delivery Dates as to which Designations are given will be chosen by American in
its sole discretion.

Section 2.05. Payment of Purchase Price. Each Purchase Price and
each Spares Purchase Price payable to American by FedEx shall be net of any
and all taxes, recording expenses, assessments, duties and similar governmental
charges and fees charged on or with respect to the sale of the Aircraft, any
and all of which amounts shall be paid by FedEx, subject, however, to the
provisions of Section 3.01. The Purchase Price for each Aircraft shall be paid
on the Delivery Date for such Aircraft, net of any applicable Deposit and the
interest calculated at the AMR Rate. The Spares Purchase Price for any Spare
Parts purchased pursuant to Article 4 shall be paid on the date the Spare Parts
being sold to FedEx are delivered by American to FedEx. The Purchase Prices,
the Spares Purchase Prices and any Deposits shall be paid by FedEx in United
States Dollars by wire transfer of *Blank space contained confidential
information which has been filed separately with the Securities and Exchange
Commission pursuant to Rule 24b-2 under the Securities Exchange Act of 1934.

Section 2.06. Deposits. FedEx will pay to American on the Business
Day next following the date of execution of this Agreement a cash deposit in
the amount of $[ * ] for each Firm Aircraft. FedEx will pay to American
within the ten-day period next following the date on which each Put Option is
exercised, a cash deposit of $[* ] in respect of the Put Option Aircraft
as to which such Put Option is exercised. FedEx will pay to American upon the
Business Day next following the exercise of any Purchase Option, a cash deposit
of $[ * ] in respect of each Purchase Option Aircraft. [ *
]. If American shall fail to perform its obligation to deliver an Aircraft in
accordance with this Agreement, American will return to FedEx, upon FedEx's
written request, any Deposits made with respect to such Aircraft, with interest
thereon calculated at a rate equal to the AMR Rate. The Deposit applicable to
a particular Aircraft, with an amount of interest thereon calculated at the AMR
Rate, will be applied to the payment of the Purchase Price of such Aircraft on
the Delivery Date. Neither the retention of any Deposit by American in
connection with the failure of FedEx to perform its obligations under this
Agreement nor the return of any Deposit by American in connection with the
failure of American to perform its obligations under this Agreement shall be
the exclusive remedy of the non-defaulting Party in connection with any such
default. Except as set forth above, American shall be entitled to retain any
interest earned on the Deposits.

Dallas/Fort Worth International Airport ("DFW"), (ii) at the option of
American, at an airport in the State of Nevada if American so advises FedEx at
least seven (7) days prior to the Scheduled Delivery Date for such Aircraft or
(iii) at such other location on FedEx's route system as American designates in
writing to FedEx at least ninety (90) days prior to the Scheduled Delivery Date
and to which FedEx consents, such consents not to be unreasonably withheld. If
any Scheduled Delivery Date is not a Business Day, the Aircraft to be delivered
shall be delivered and accepted on the Business Day next preceding the
Scheduled Delivery Date.

Section 3.02. Inspection, Flight Checks and Discrepancies. (a) FedEx
shall have access to each Aircraft no later than [ * ] prior to
the Scheduled Delivery Date for such Aircraft at American's maintenance
facility at the Tulsa International Airport in Tulsa, Oklahoma ("TUL"). At
such time, FedEx shall have the right to: (i) conduct all ground inspections
reasonably necessary to determine whether the Aircraft is in Delivery
Condition, including, but not limited to, engine borescopes conducted in
accordance with Exhibit R, (ii) functionally ground and flight check such
Aircraft in accordance with the requirements and procedures contained in the
McDonnell Douglas Model MD-11 Production Flight Procedure Manual (the "MDAC
PFPM") applicable to aircraft that are completing a C Check and (iii) conduct
on each Engine being delivered (other than a Non-Conforming Engine) a Power
Assurance Run Test to ensure that the exhaust gas temperature margin for such
Engine conforms to the requirements of Section 3.06(i)(B)(4). Subject to
Section 3.02(b), any such checks or test flights shall be of a reasonable
duration. In determining if an Aircraft is in Delivery Condition, if there are
differences in the tolerances stated in the MDAC PFPM and the American Program,
the more lenient tolerances will apply.

(b) The initial flight test of an Aircraft shall not be more than [ *
] in duration. American will permit at least [ *
] of FedEx to observe any functional flight check of an Aircraft
made in conjunction with the Delivery of such Aircraft. During the functional
flight check, American shall provide a pilot who shall function as
pilot-in-command and who shall maintain operational control and responsibility
for the Aircraft. FedEx shall provide a pilot who shall occupy a pilot's seat
(left or right, at the discretion of the pilot- in-command). FedEx's pilot
shall physically exercise the flight controls in such phases of flight as
necessary to verify the functional operation of the Aircraft. Insurance for
all functional flight checks shall be provided by American, at its sole expense
under its existing insurance policies, provided, however, that any FedEx
personnel who are to be present on such Aircraft during any such flight shall
execute and *Blank space contained confidential information which has been
filed separately with the Securities and Exchange Commission pursuant to Rule
24b-2 under the Securities Exchange Act of 1934.

-16-
<PAGE> 23
deliver to American prior to such flight a release and waiver of liability
containing terms and conditions reasonably satisfactory to American. American
shall provide the fuel necessary for such flight check.

(c) Upon completion of functional ground and flight check of an
Aircraft, American shall, at American's expense and in accordance with the
applicable criteria set forth in the American Program: (i) correct and/or
clear any items noted in the Aircraft's log book by American and which remain
un-cleared or un-corrected at the Scheduled Delivery Date and (ii) correct
and/or clear any discrepancies of the Aircraft from the Delivery Condition
otherwise noted during the functional ground and flight checks of such
Aircraft. If an additional flight check is required to demonstrate that a
discrepancy from the Delivery Condition for such Aircraft has been corrected,
such additional flight check shall be conducted in the manner set forth in
Section 3.02(a) and (b). Any additional flight check made to inspect the
correction of any discrepancy of such Aircraft from the required Delivery
Condition previously noted shall be limited to the time necessary to inspect
such discrepancy. If additional discrepancies from the Delivery Condition are
noted during a subsequent flight check (or the original discrepancy is not
satisfactorily corrected), American shall correct the discrepancy from the
Delivery Condition noted during the subsequent flight check. Notwithstanding
the foregoing, American shall not be required to correct or clear any items or
discrepancies of the Aircraft from Delivery Condition that are (x) cosmetic in
nature, (y) related solely to any Passenger Parts or (z) which the Parties
agree in writing in the Aircraft Delivery Certificate to correct and/or clear
after the Delivery of the Aircraft.

(d) Upon completion of the items in Sections 3.02(a) through 3.02(c)
on an Aircraft, FedEx shall execute and deliver to American the Aircraft
Delivery Certificate for such Aircraft pursuant to which FedEx shall certify
that it has accepted the Aircraft and that the Aircraft is in the Delivery
Condition, except to the extent that (i) any remaining discrepancies of the
Aircraft from the Delivery Condition are noted by the Parties in such Aircraft
Delivery Certificate or (ii) the failure of the Aircraft to meet Delivery
Condition requires an Adjustment (as defined below). Thereafter, American
shall not change or alter the configuration or operate such Aircraft for any
reason prior to Delivery (except as necessary to ferry such Aircraft to any
other location at which Delivery will occur) without the prior written consent
of FedEx.

deliver to FedEx the Data with respect to such Aircraft;

(v) American shall execute and deliver to FedEx an assignment of
any warranties with respect to the Aircraft that are assignable by American by

of more than a nominal amount;

(vi) Concurrently with the delivery of the Warranty Bill of Sale
described in clause (ii) above, American shall cause the FAA Bill of Sale
executed by American to be filed and recorded with the FAA Aircraft Registry in
Oklahoma City, Oklahoma and FedEx shall cause an Application for Registration
of the Aircraft to be filed with the FAA Aircraft Registry. FedEx shall be
responsible for all costs of filing or recording of the FAA Bill of Sale, the
Application for Registration of the Aircraft and any such other acceptance
certificates, delivery receipts and any other documents as shall be agreed to
by the Parties as appropriate for the sale, purchase and Delivery of such
Aircraft;

(vii) At the time and upon completion of Delivery of each Aircraft,
Messrs. Daugherty, Fowler & Peregrin, special FAA counsel to FedEx, shall
confirm to FedEx that such counsel will furnish FedEx its opinion, addressed to
FedEx, to the effect that: (A) the FAA Bill of Sale with respect to the
Aircraft being delivered by American to FedEx and the FAA Application for
Registration relating thereto have been duly filed with the FAA; (B) legal
title to such Aircraft is vested in FedEx or its designee, and (C) such
Aircraft, including the Engines conveyed to FedEx in connection with such
Aircraft, is free and clear of all Liens, other than Liens arising by, through
or under FedEx or its designee, if any, that has taken title to the Aircraft.
Such opinion may be subject to the type of assumptions and qualifications
regularly included by experienced FAA counsel in similar opinions; and

(viii) If a Non-Conforming Engine which is not conveyed to FedEx
pursuant to Section 3.03(d) is installed on the Aircraft at the Delivery Date,
each of American

and FedEx shall execute and deliver the Engine Lease Agreements with respect to
such Non-Conforming Engine and applicable Delayed Delivery Engine.

Section 3.05. Delayed Delivery. (a) If FedEx is obligated to accept
delivery of and purchase an Aircraft tendered by American for delivery on a
Scheduled Delivery Date, which Aircraft is in Delivery Condition and FedEx
fails to accept such Aircraft for delivery in accordance with this Agreement,
unless such failure is an Excusable Delay, FedEx will [*
]
If American is unable to deliver an Aircraft on a Scheduled Delivery Date,
unless such delay is an Excusable Delay (other than one arising as a result of
a Force Majeure Event involving any work stoppage, work slow down, other labor
or work action or labor dispute, if and to the extent such Excusable Delay
exceeds four (4) weeks in duration), [ *
] The payment of any such amounts shall not be
the exclusive remedy of American if FedEx fails to accept delivery of an
Aircraft on a Scheduled Delivery Date other than in circumstances constituting
an Excusable Delay nor the exclusive remedy of FedEx if American fails to
deliver an Aircraft on a Scheduled Delivery Date other than in circumstances
constituting an Excusable Delay.

(b) Notwithstanding the foregoing, with respect to non-excusable
delays resulting from American's actions or omissions, American shall not be
required to pay interest on the Purchase Price of any Aircraft as set forth
above if (i) delivery of such Aircraft is delayed for [ * ] or
less and (ii) the aggregate number of days for which deliveries of all the
Aircraft have been delayed [ * ]
If, as to non- excusable delays resulting from American's actions or omissions,
the number of days by which any delivery of an Aircraft is delayed exceeds [ *
] or the number of days by which all deliveries of Aircraft are delayed exceeds
[ *
] in the aggregate, interest (computed as provided above) on
the Purchase Price of the Aircraft as to which a delay in excess of [ *
] occurs (less the amount of applicable Deposit) or the aggregate Purchase
Prices of the Aircraft as to which aggregate delays in excess of [ *
] occur (less the amount of applicable Deposit) shall be paid by American to
FedEx as provided above for each day for which deliveries of the Aircraft by
American are delayed. Notwithstanding the foregoing, with respect to
non-excusable delays resulting from FedEx's actions or omissions, FedEx shall
not be required to pay interest on the Purchase Price of any Aircraft as set
forth above if (i) its acceptance

with the Securities and Exchange Commission pursuant to Rule 24b-2 under the
Securities Exchange Act of 1934.

-23-
<PAGE> 30
of an Aircraft is delayed for [ * ] or less and (ii) the aggregate
number of days for which FedEx's acceptances of all the Aircraft are delayed
does not exceed [ * ] If, as to non-excusable delays resulting
from FedEx's actions or omissions, the number of days by which any delivery of
an Aircraft is delayed exceeds [ * ] or the number of days by which
all deliveries of Aircraft are delayed exceeds [ * ] in the
aggregate, interest (computed as provided above) on the Purchase Price of the
Aircraft as to which the delay in excess of [ *
] occurs or the aggregate Purchase Prices of the Aircraft as to which
aggregate delays in excess of [ * ] occur shall be paid by FedEx to
American as provided for above for each day for which the acceptances of
the
Aircraft by FedEx are delayed.

(c) If an Aircraft which has been designated for delivery to FedEx on
a particular Scheduled Delivery Date sustains any damage or is partially
destroyed and such damage or partial destruction can be repaired or restored
and such Aircraft can be tendered for Delivery on the date (the "Partial
Casualty Delivery Date") that is the later to occur of (i) the Scheduled
Delivery Date with respect to such Aircraft or (ii) the date which is [ *
] after the occurrence of such damage or partial destruction, as promptly as
practicable after the occurrence of the damage or destruction of such Aircraft,
American shall notify FedEx in writing of such occurrence and whether American
elects (i) at American's sole cost and expense, to repair or restore the
damaged or partially destroyed Aircraft so that it will be in Delivery
Condition or (ii) to substitute another Aircraft, if any, for the damaged
Aircraft. Any repair required by damage to or partial destruction of the
Aircraft shall not (i) impose any restrictions on the FAA-certified
limitations, performance or operation as set forth in the Manufacturer's
FAA-approved Airplane Flight Manual for the Aircraft or (ii) materially impair
the fuel mileage performance of the Aircraft or (iii) increase the empty weight
of the Aircraft by more than [ * ]pounds.

(d) If, before the Delivery Date of any Committed Delivery (as
defined below), one or more Aircraft (each a "Casualty Aircraft") are lost or,
in American's sole judgment, substantially completely destroyed, or if American
determines, in its sole judgment, that repairing any substantial damage to any
Aircraft would be uneconomical, then American shall designate or re-designate
other Aircraft, if any, pursuant to Section 2.04 (without regard to the times

SPARE PARTS

Section 4.01. MD-11 Spare Parts List. (a) On the date of
execution of this Agreement, American will provide FedEx with the Spares List
which will be a list of rotable spare parts that American held in its inventory
as of January 20, 1995 and that are unique to McDonnell Douglas Model MD-11
aircraft or that can be used on the McDonnell Douglas Model MD-11 and Model
DC-10 aircraft but no other aircraft within American's fleet. The Spares List
will set forth for each type of MD-11 Spare Part, American's and the
manufacturer's part numbers for each type of MD-11 Spare Part, the quantity of
each type of MD-11 Spare Part held by American at the date on which the Spares
List is delivered and the Average Unit Price for each type of MD-11 Spare Part.
The Spares List will be provided via electronic storage media mutually
acceptable to American and FedEx. American will also provide FedEx with a hard
copy of the Spares List.

Section 4.02. MD-11 Spare Parts Purchase Obligation. (a)
On each date on which FedEx is obligated to accept delivery of a Firm Aircraft
pursuant to this Agreement, American will sell to FedEx, and FedEx will
purchase from American, MD-11 Spare Parts having an average, aggregate Average
Unit Price of $[ * ] for each Firm Aircraft as to which Delivery occurs
or which FedEx is obligated to *Blank space contained confidential information
which has been filed separately with the Securities and Exchange Commission
pursuant to Rule 24b-2 under the Securities Exchange Act of 1934.

<PAGE> 37
purchase; provided, however, that so long as the Delivery of three Aircraft
occurs in each of the years from 1996 through 1999 (i) the aggregate Average
Unit Prices of MD-11 Spare Parts that shall be sold by American to FedEx, and
purchased by FedEx from American, in each year from 1996 through 1999 shall be
$[ * ]. On each date on which FedEx is obligated to accept
delivery of a Put Option Aircraft pursuant to the exercise of a Put Option or a
Purchase Option Aircraft, American will sell to FedEx, and FedEx will purchase
from American, MD-11 Spare Parts having an aggregate Average Unit Price of $[ *
] for each of the first eighteen (18) Aircraft and $[ * ] for
the nineteenth (19th) Aircraft as to which Delivery occurs or which FedEx is
obligated to purchase.

(b) If the MD-11 Spare Parts are being purchased in
conjunction with the purchase by FedEx of a Firm Aircraft or an Aircraft as to
which American has exercised a Put Option, the Spares Purchase Price for such
MD-11 Spare Parts shall be as set forth in Section 1 of Exhibit Q. If the
MD-11 Spare Parts are being purchased in conjunction with the purchase by FedEx
of any Purchase Option Aircraft, the Spares Purchase Price for such MD-11 Spare
Parts shall be determined by reference to Section 2 of Exhibit Q. FedEx will
pay to American the Spares Purchase Price for the portion of the MD-11 Spare
Parts being purchased on the date such MD-11 Spare Parts are delivered to FedEx
by American.

(c) The MD-11 Spare Parts that American will sell to FedEx
and FedEx will purchase from American in any lot of MD-11 Spare Parts pursuant
to the first sentence of Section 4.02(a) will be a pro rata portion of each
type of MD-11 Spare Part, based on a total of nineteen Aircraft. If the number
of a particular type of MD-11 Spare Parts held by American on any Delivery Date
does not permit the mix of MD-11 Spare Parts sold to FedEx in each such lot to
be a perfectly pro rata portion of all of the various types of MD-11 Spare
Parts, American and FedEx shall cooperate to set the mix of MD-11 Spare Parts
so that the inventories of MD-11 Spare Parts of American and FedEx shall be as
nearly pro rata as possible at all times. If for operational reasons American
or FedEx shall desire to change the mix of MD-11 Spare Parts that American
would deliver on any date, American and FedEx shall attempt in good faith, but
shall not be obligated, to effect such change in the mix of MD-11 Spare Parts
in order to accommodate each other's operational requirements. If American and
FedEx shall change such a mix of MD-11 Spare Parts in any lot of MD-11 Spare
Parts delivered to FedEx by American, the mix of MD-11 Spare Parts delivered to
FedEx in the next lot shall contain such MD-11 Spare Parts as are necessary to
cause compliance with requirements of the first two sentences of this Section
4.02(c) once such MD-11 Spare Parts are purchased by and delivered to FedEx.

Section 4.03. Spare Engine, Spare APU and Spare Thrust
Reverser Purchase Obligation. (a) (i) American will sell to FedEx, and FedEx
will purchase from American, on the dates and for the Spares Purchase Prices
set forth in or determined as set forth in Exhibit Q, the Spare Engines set
forth in Exhibit Q. If FedEx desires to change the quick engine change
configuration of any Spare Engine delivered by American to FedEx, American
shall provide to FedEx in exchange for conveyance by FedEx to American of the
Parts removed from the Spare Engine in question, the Parts necessary to change
the quick engine change configuration of such Spare Engine to a tail
configuration or a wing configuration, as the case may be, if American has the
necessary parts in its inventory of spare Parts and such spare Parts are
determined by American, in good faith, to be surplus to its needs. If American
delivers any such spare Parts to FedEx, FedEx shall deliver to American any of
the Parts removed from such Spare Engine in connection with the change in the
configuration of such Spare Engine. Upon its delivery by American to FedEx,
each of the first five (5) Spare Engines delivered by American to FedEx will be
in the condition an Engine is required by Section 3.06(a)(i)(B), 3.06(a)(iii)
and 3.06(a)(iv) to be in upon its delivery by American to FedEx, and FedEx
shall have the right to conduct an engine borescope on each such Spare Engine
delivered in accordance with Exhibit R. The Spares Purchase Price for each of
the first five (5) Spare Engines shall be adjusted in accordance with Exhibit
M.

(ii) American will, at its sole option, either (A) deliver each Spare
Engine to be sold to and purchased by FedEx on one of the last five (5) Spare
Engine delivery dates set forth in Exhibit Q (each a "Last Group Engine" and
collectively, the "Last Group Engines") without such Last Group Engine having
been operated on wing since its last EHM, in which case the Spares Purchase
Price for such Last Group Engine shall be adjusted in accordance with Exhibit
M, or (B) if any such Last Group Engine does not comply with the standard in
clause (A) of this sentence, adjust the Spares Purchase Price of such Last
Group Engine in accordance with the adjustment formula set forth in Exhibit T;
provided, however, that the obligation set forth in clause (A) of this sentence
shall be reduced as to and no longer apply to one (1) such Last Group Engine
for each Spare Engine among the first five (5) Spare Engines delivered by
American to FedEx that is delivered without having been operated on wing since
its last EHM. Upon delivery of any Last Group Engine to which the obligation
set forth in clause (A) of the first sentence of this Section 4.03(a)(ii) no
longer applies, the Spares Purchase Price of such Last Group Engine shall be
adjusted in accordance with Exhibit M (instead of Exhibit T). Each Last Group
Engine delivered will be in the condition required by Section 3.06(a)(iii) and
Section 3.06(a)(iv), and FedEx shall have the right to conduct an engine
borescope on each such Last Group Engine delivered in accordance with Exhibit
R. At the time of delivery of any Last Group Engine whose Spares Purchase
Price is adjusted in accordance with clause (B) of the foregoing
sentence, American will issue to

-32-
<PAGE> 39
FedEx a credit memorandum for [ * ] of the cost of an EHM
(the "EHM Credit") on a General Electric CF6-80C2D1F engine operated by FedEx
which was acquired from American (a "Purchased Engine"). The EHM Credit will
be redeemable by FedEx at any time during the [ * ] period
commencing on the date it is issued to pay a portion of the cost of the EHM
performed on a Purchased Engine. Subject to the foregoing sentence, if any
Last Group Engine does not comply with the standard in clause (A) of the first
sentence of this Subsection 4.03(a)(ii), FedEx must use an EHM Credit, if one
is available to it, to pay a portion of the cost of an EHM on such Last Group
Engine to be accomplished by American when such Last Group Engine next requires
an EHM. FedEx may apply two EHM Credits previously issued to it to the payment
of the cost of the EHM on such engine. The cost of an EHM on an engine against
which an EHM Credit may be applied shall be the cost of an EHM as set forth in
Table A to Exhibit M for the year in which the EHM on such engine is
accomplished. The costs set forth in Table A to Exhibit M do not include the
cost of any Life Limited Parts replaced during an EHM. To use an EHM Credit,
FedEx must deliver its engine to American at TUL or such other location to
which American and FedEx mutually agree. Upon delivery of the engine to
American's maintenance facility, American will perform the EHM work on the
engine and provide the materials required in performing the EHM, other than
Life Limited Parts. American will invoice FedEx for the balance of the cost of
an EHM not covered by the application of the EHM Credit, including, without
limitation, the cost of the Life Limited Parts replaced, within 30 days of the
completion of the EHM. FedEx will pay the amount of American's invoice
promptly after receipt of such invoice. FedEx will be responsible for the
costs of packing and shipping the engines to and from American's maintenance
facility for such an EHM.

(b) American will sell to FedEx, and FedEx will purchase from
American, on the dates and for the Spares Purchase Prices set forth in or
determined as set forth in Exhibit Q, the Spare APU's set forth in Exhibit Q.
Upon its delivery by American to FedEx, such Spare APU's will (i) be in
serviceable condition with an American Serviceable Tag attached to it and (ii)
will not have been installed on an aircraft subsequent to the Spare APU's last
accomplished APU C&R (as defined below) or APU EHM (as defined below), which
APU C&R or APU EHM shall have been accomplished through an American repair shop
or a FAA-approved third party repair facility. "APU C&R" shall mean a check
and repair of a Spare APU involving disassembly only to the extent required to
correct malfunctions and/or obvious visual damage. "APU EHM" shall mean the
complete disassembly and refurbishment of the LP Compressor and LP Turbine
sections, HP Compressor and HP Turbine sections of a Spare APU and the check &
repair of the gearbox and all components of the Spare APU. *Blank space

(c) American will sell to FedEx, and FedEx will purchase from
American, on the date and for the Spares Purchase Prices set forth in or
determined as set forth in Exhibit Q, the Spare Thrust Reversers as set forth
in Exhibit Q. Upon its delivery by American to FedEx, each Spare Thrust
Reverser will (i) be in serviceable condition with an American Serviceable Tag
attached to it and (ii) will not have been installed on an aircraft subsequent
to the Spare Thrust Reversers' last accomplished Reverser C&R (as defined
below) or RHM (as defined below), which Reverser C&R or RHM shall have been
accomplished through an American repair shop or a FAA-approved third party
repair facility. "Reverser C&R" shall mean a check and repair of the Spare
Thrust Reverser involving a complete tap check of the translating cowl and core
cowl for delamination, an overall check of the unit for external damage,
excessive wear or binding, a check of the flexdrive shaft cores and casings for

to the extent necessary to accomplish all the required checks and
reconditioning of a Spare Thrust Reverser as specified in the American Program
in which all components will be checked and repaired and sent to their
appropriate repair sources for repair processing.

Section 4.04. Effect of Expiration of Put Options on Certain
Spare Parts Purchase Obligations. If (i) any Put Option expires as to a Put
Option Aircraft or (ii) FedEx does not exercise a Purchase Option as to a Put
Option Aircraft which has a Scheduled Delivery Date on which a Spare Engine,
Spare APU or Spare Thrust Reversers is to be sold to FedEx, American will have
no obligation to sell, and FedEx will have no obligation to purchase, such
Spare Parts otherwise to be sold and purchased by the Parties on such Scheduled
Delivery Date. If any remaining Put Options are not cancelled by FedEx in
accordance with Section 2.02(d) after American fails to exercise a Put Option,
the Scheduled Delivery Date on which each of the remaining, unpurchased Spare
Engines, Spare APU's or Spare Thrust Reversers are to be sold by American to
FedEx, and purchased by FedEx from American as set forth in Exhibit Q (an
"Original Sale Date") shall be changed to be the Scheduled Delivery Date for a
Put Option Aircraft as set forth in Exhibit Q next scheduled to occur after the
Original Sale Date of each such Spare Engine, Spare APU or Spare Thrust
Reversers (a "Modified Sale Date") and the obligation of American to sell and
of FedEx to purchase the Spare Engines, Spare APU's and/or Spare Thrust
Reversers on the last remaining, uncancelled Scheduled Delivery Date for a Put
Option Aircraft as set forth in Exhibit Q shall be terminated and without
further force or effect. If American shall sell, and FedEx shall be obligated
to purchase, a Put Option Aircraft on the Modified Sale Date for any Spare
Engine, Spare APU or Spare Thrust Reversers, American shall sell such Spare
Part or Spare Parts scheduled to be sold and purchased by the Parties on such
Modified Sale Date for the Spares Purchase Price or Spares Purchase Prices, as
the case may

-34-
<PAGE> 41
be, on the Modified Sale Date as set forth in or determined in accordance with
Exhibit Q.

Section 4.05. Designation of MD-11 Spare Parts to be Acquired and
Delivery. At least [ * ] days prior to the proposed date for
the delivery of a lot of MD-11 Spares to be purchased by FedEx from American,
FedEx shall notify American in writing of the date on which it will take

that it desires to have in such lot of MD-11 Spare Parts and the destination
within the forty- eight (48) contiguous United States to which the MD-11 Spare
Parts are to be shipped. As to any other Spare Parts, [ *
] days prior to the proposed date of delivery FedEx shall give American
written notice of the destination within the United States to which such Spare
Parts are to be shipped. American shall ship all of the Spare Parts to
Memphis, Tennessee, unless it is mutually agreed in writing that any or all of
the Spare Parts will be shipped to another destination within the forty-eight
(48) contiguous United States.

Section 4.06. MD-11 Spare Parts Documentation. At the time of
delivery of the MD-11 Spare Parts sold by American to FedEx, the MD-11 Spare

DOCUMENTATION

Section 6.01. Availability of Documentation. FedEx may, upon
giving American [ * ] review Aircraft and Engine specific
historical engineering, operational and maintenance records, manuals and
documentation forming a part of the Data and specific to the next Aircraft to
be delivered. Such review will occur during the [ * ] period
prior to the Scheduled Delivery Date for such Aircraft at American's Tulsa,
Oklahoma Maintenance and Engineering Center. Such review shall be done during
normal working hours and shall not unreasonably interfere with the business
operations of American at such site.

Section 6.02. Technical Data and Documents. (a) American shall
provide to FedEx all Data applicable to each Aircraft, Engine and Spare Engine
on or before the Delivery Date with respect to such Aircraft, provided,
however, that any Aircraft Records or Engine Records generated within the [ *
]

-39-
<PAGE> 46
immediately prior to the Delivery Date may be delivered to FedEx within the
[ * ] next following the Delivery Date of the relevant Aircraft
to FedEx. If FedEx shall need any other information pertaining to the Aircraft
cor an Engine thereon after the delivery of the Aircraft Records or Engine
Records, as the case may be, during the [ *
] period immediately after the delivery
of the Aircraft Records, upon FedEx's written request, American will search its
records for such information. If such information is found, American shall
deliver such information to FedEx at American's expense. American shall not be
required to create any records regarding the Aircraft, any Engine or any Part
that American is not required to retain in its records by the FAA under the
American Program. If American is normally required by the FAA under the
American Program to retain a particular Aircraft Record or Engine Record
respecting an Aircraft or any Part thereof, but during the [ *

] period immediately after delivery of the Aircraft Records or
Engine Records, as the case may be, such Aircraft Record or Engine Record or a
part of such Aircraft Record or Engine Record is found to be missing,
incomplete or in error with respect to any Aircraft delivered to FedEx,
American will, at its sole option, either create an accurate and complete
reconstruction of such Aircraft Record or Engine Record, replace the Part or
Parts on the Aircraft as to which the missing, incomplete or erroneous Aircraft
Record or Engine Record relates or take such other corrective action as shall
permit FedEx to operate the Aircraft in accordance with its then current
operations specifications, as approved by the FAA primary maintenance inspector
assigned to FedEx.

(b) At the Delivery Date of any Aircraft, the Aircraft Records and/or
Engine Records relating to the Aircraft and Engines delivered to FedEx by
American as provided above shall be, to the best of American's knowledge,
accurate and complete in accordance with the aircraft records requirements of
FAR 121.380 at the time of the delivery of such Aircraft Records and/or Engine
Records to FedEx. To the extent any such Aircraft Record or Engine Record is
not accurate or complete, FedEx's sole remedy shall be to cause American, at
its sole option and expense, to research and correct such inaccurate or
incomplete Aircraft Record or Engine Record, replace the Part or Parts on the
Aircraft as to which the missing, incomplete or erroneous Aircraft Record or
Engine Record relates, or take such other corrective action as shall permit
FedEx to operate the Aircraft in accordance with its then current operations
specifications, as approved by the FAA primary maintenance inspector assigned
to FedEx.

(c) If the FAA changes the regulations or issues national policy
guidance related to existing regulations pertaining to any documentation
required to *Blank space contained confidential information which has been
filed separately with the Securities and Exchange Commission pursuant to Rule
24b-2 under the Securities Exchange Act of 1934.

substantiate Airworthiness Directive compliance, American shall provide to
FedEx, to the extent it is available, all such required documentation not
previously delivered for any previously delivered Aircraft, Engine, Gear or
APU.

(d) Except as noted in Exhibit D, American shall provide to FedEx (i)
one legible, reproducible copy of each item of Data that is not related to any
particular Aircraft (which shall be delivered on the Delivery Date for the
first Firm Aircraft) and the subsequent revisions thereto occurring prior to
the last Delivery Date (each of which revisions shall be delivered on the
Delivery Date next following the date on which the revision is issued), (ii)
one legible, reproducible copy of any item of Data (other than the Aircraft
Records) related to each Aircraft that is delivered to FedEx by American and
(iii) originals (or if an original copy is not available, one legible
reproducible copy) of the Aircraft Records with respect to each Aircraft that
is delivered to FedEx by American. All items of Data delivered shall be in
hard copy except as noted in Exhibit D. If American does not have hard copy,
the Data shall be provided on microfilm or by other agreed medium. At FedEx's
request, all manufacturer's manual revision services for the Aircraft, if any,
shall be transferred to FedEx.

(e) When Data are forwarded to FedEx, American shall include a list
of those items using the reference numbers in Exhibit D.

All Data not delivered with an Aircraft shall be forwarded to:

ASSIGNMENT OF WARRANTIES, SERVICE LIFE POLICIES
AND PATENT INDEMNITIES

Section 7.01. Assignment of Warranties. At Delivery of each
Aircraft, an Assignment of Assignable Manufacturer's Warranties in the form of
Exhibit G shall be executed by American and delivered to FedEx pursuant to
which American will assign to FedEx, effective upon Delivery of such Aircraft,
all of American's interests in any and all existing and assignable warranties,
service life policies and patent indemnities of manufacturers and maintenance
and overhaul providers relating to such Aircraft. Further, upon FedEx's
request, American shall (i) give written notice to any such manufacturers and
maintenance and overhaul providers of the assignment of such warranties,
service life polices and patent indemnities to FedEx,

-41-
<PAGE> 48
and (ii) at FedEx's expense, take all such actions as may be reasonably
requested by FedEx in assisting FedEx in the enforcement of its rights pursuant
to this Article 7. Notwithstanding the foregoing, to the extent American may
assign any warranty, service life policy and patent indemnity only with the
consent of the provider of such, American will use its commercially reasonable
efforts to obtain any required consent to such an assignment, provided,
however, that American shall not be required to make any payment, give up any
rights or make any other concession to any provider in order to obtain any such
consent. In connection with the assignment of the Aircraft Support Services
provisions of Exhibit C to the Purchase Agreement by and between the
Manufacturer of the Airframes and American, dated August 3, 1989, as amended
and supplemented (the "MD-11 Purchase Agreement"), FedEx agrees to be bound by
the terms and provisions of Article 13 of, and Exhibit C to, the MD-11 Purchase
Agreement, copies of which have been provided to FedEx.

ARTICLE 8
PAYMENT OF TAXES

Section 8.01. Payment of Taxes by FedEx. (a) The Purchase Price
of an Aircraft and the Spares Purchase Prices do not include the amount of any
sales, use, withholding, transfer or excise taxes whatsoever. Except as
provided in Section 8.01(b) and Section 8.02 hereof, any and all taxes,
excises, duties and assessments whatsoever (including any related penalty,
interest or other additions to tax) arising out of the sale, transfer or
delivery of the Aircraft or the Spare Parts under this Agreement, or the
ownership, possession, condition, maintenance, use, operation or disposition of
the Aircraft after Delivery or any Spare Parts after their delivery to FedEx,
in any manner levied, assessed or imposed by any government or subdivision or
agency thereof having jurisdiction, shall be the sole responsibility and
liability of FedEx and FedEx shall indemnify and hold American harmless from
any and all such taxes, excises, duties and assessments whatsoever. American
and FedEx will cooperate in good faith and take such reasonable actions as are
practicable to minimize or, if possible, eliminate any such taxes, excises,
duties or assessments.

(b) The indemnity provided for in Section 8.01(a) shall not extend to
any of the following:

(i) taxes based upon, measured by or with respect to the net income,
gross receipts in the nature of an income tax not in the nature of a transfer
tax, items of tax preference or minimum tax or excess profits, capital,
franchise, net worth or conduct of business or other similarly-based taxes of
American;

(ii) any penalty, interest or other additions to taxes related to
taxes imposed on American that would not have been imposed, but for the willful
misconduct or gross negligence of American; or

-42-
<PAGE> 49
(iii) taxes, excises, duties or assessments imposed by the State of
[.* ]

(c) With respect to any tax which FedEx has assumed responsibility
for under this Article 8, FedEx shall either (i) pay (x) at the Delivery Date
for an Aircraft, (y) at the delivery date of any Engine sold to FedEx and not
conveyed by American to FedEx at the Delivery Date for an Aircraft, or (z) at
the delivery date for any Spare Parts sold by American to FedEx, all sales or
other similar taxes payable with respect to the sale and/or purchase of such
Aircraft, Engines or Spare Parts, respectively, or (ii) provide to American an
exemption certificate, resale certificate, or other evidence reasonably
acceptable to American that the sale and purchase of any Aircraft, Engine or
Spare Part is exempt from any such tax. Other evidence includes, but is not
limited to, a letter specifying the applicable taxing authority's statute,
regulation, rule or case law authority providing for such exemption; provided,
however, that acceptance of such certificates or other evidence by American
shall not constitute willful misconduct or gross negligence by American for
failure to collect taxes determined to be due.

(d) If any tax, excise, duty or assessment described in this Section
8.01 for which FedEx has assumed the responsibility for payment pursuant to
this Article 8 is levied, assessed or imposed upon American, American shall
promptly give FedEx notice of such levy, assessment or imposition, whereupon
FedEx shall promptly pay and discharge the same or, if permitted by law, may
contest or protest such liability before payment. If American fails to notify
FedEx, FedEx will be relieved of its indemnity obligations under this Section
8.01 with respect to that tax to the extent such failure materially adversely
impacts FedEx. Upon the written request and at the sole expense of FedEx,
American shall reasonably cooperate with FedEx in contesting or protesting the
validity or application of any such tax (including, but limited to, permitting
FedEx to proceed in American's name if required or permitted by law, provided,
in each case, that such contest does not involve, or can be separated from, the
contest of any tax or other issues unrelated to the transactions described in
this Agreement). If proceeding in American's name, FedEx must first receive a
power of attorney from American which American may not unreasonably withhold,
and, further, any retention of outside counsel to assist FedEx must be mutually
agreed upon by FedEx and American. In lieu of permitting FedEx to proceed
using American's name, American may, if permitted by law, assign its claim to
FedEx as the real party in interest with respect to such claim. FedEx also
shall have the right to participate in any contest conducted by American with
respect to a tax or other charge indemnifiable under this Article 8, including,
without limitation, the right to attend conferences with the taxing authority
and the right to review submissions to the taxing authority or any court to the
extent,

but only to the extent, such contest does not involve, or can be separated
from, the contest of any tax or issues unrelated to the transactions
contemplated in this Agreement. In the event American shall receive a refund
of all or any part of such tax, excise, duty or assessment (including a refund
of interest and penalties, if any, in connection therewith) which FedEx has
paid and discharged, the amount of such refund shall promptly be remitted to
FedEx by American, less any expenses of American associated with contesting
and/or protesting the validity or application thereof which have not been
previously reimbursed by FedEx.

Section 8.02. Tax Consequences of Certain Deliveries. (a) If the
delivery of the Aircraft at any destination other than one in [ * ] or [ *
] would result in an increased state, federal or local sales, transfer or
similar tax being payable by FedEx in connection with the delivery of the
Aircraft, FedEx may, in its sole discretion, withhold its consent to take the
Delivery of such Aircraft in that state unless American agrees to indemnify
FedEx for any such increased tax.

(b) If the delivery of the Aircraft to FedEx in [ * ] results in
any sales, transfer or similar tax being imposed on FedEx with respect to such
Aircraft as a result of the tender of the Aircraft in [ * ], American will
agree to indemnify FedEx or provide FedEx with a written statement from
the taxing authority in [ * ] that such sale is exempt from tax in [ *
] and that, if the exemption is lost, American will indemnify FedEx for any tax
due unless the loss was due to the negligence or willful misconduct of FedEx.

(c) If any Spare Parts are delivered to FedEx at a location other
than Tennessee, American shall indemnify FedEx for any (or an increased)
federal, state or local sales, transfer or similar tax imposed on FedEx with
respect to such Spare Parts unless such other delivery location was mutually
agreed upon or was chosen at the request of FedEx in which case FedEx shall
indemnify American if the delivery of any of the Spare Parts to FedEx would
result in any or any increased federal, state or local sales, transfer or
similar tax to American. If the delivery of any Spares Parts to FedEx would
result in any (or an increased) federal, state or local sale, transfer or
similar tax to American or FedEx, as the case may be, American and FedEx will
choose a jurisdiction on FedEx's route system within the contiguous forty-
eight (48) United States in which to make such delivery or re-delivery to
minimize such tax or eliminate such tax, if possible.

(d) If the delivery of a Delayed Delivery Engine or Replacement
Engine by American to FedEx or the re-delivery of a Non-Conforming Engine to
American by FedEx at the location of the Aircraft on which the Delayed Delivery
Engine or Replacement Engine will be installed results in any (or an
increased) federal,

Securities Exchange Act of 1934.

foreign, state or local sales, transfer or similar tax being imposed on FedEx,
American will indemnify FedEx for the tax or the increased amount of the tax to
the extent, but only to the extent, that FedEx would not have been responsible
for the payment of an equivalent amount of tax if the Delayed Delivery Engine
or Replacement Engine had been installed on the Aircraft at the time of the
Delivery of such Aircraft.

Section 8.03. After-Tax Basis. Any payment of an indemnity pursuant
to this Article 8 shall be made on a basis such that any payment received or
deemed to have been received by an indemnified party shall be supplemented by a
further payment to such party so that the sum of the two payments, after
deduction of all taxes resulting from the receipt or accrual of such payments,
shall be equal to the payment received or deemed to have been received.

ARTICLE 9
EXCUSABLE DELAY

Section 9.01. Excusable Delay. (a) Subject to Section 3.05,
neither Party shall be responsible to the other Party for any Excusable Delay
in the discharge and performance of its respective obligations and duties under
this Agreement or for any delay or failure in the discharge and performance of
its respective obligations and duties under this Agreement as a result of the
action or omission of the other Party.

Section 9.02. Time Limits on Excusable Delays. Notwithstanding the
provisions of Section 3.05, if an Excusable Delay shall have caused the delay
of the Delivery of an Aircraft on a Scheduled Delivery Date (i) until a date
after the Partial Casualty Delivery Date as to any Aircraft described in
Section 3.05(c), (ii) until a date after the Casualty Delivery Date, as to any
substitute Aircraft as described in Section 3.05(d) or (iii) for a period of
more than twenty-eight (28) consecutive days after the Scheduled Delivery Date
in every other instance, the Party not claiming the right to delay performance
of its obligations shall have the right (x) to terminate its obligations with
respect to the Delivery of such Aircraft at any time prior to the Delivery of
such Aircraft or a substitute Aircraft therefor or (y) to permit the other
Party to complete its performance in connection with the Delivery of such
Aircraft. If a Party chooses to terminate its obligations with respect to the
Delivery of an Aircraft or a substitute Aircraft therefor, the Party claiming
the Excusable Delay shall have no further obligation with respect to the
Delivery of the Aircraft as to which the Excusable Delay occurred. To the
extent an Excusable Delay relates to the performance of any obligation other
than one respecting the Delivery of an Aircraft, such delay shall be an
Excusable Delay for a period not to exceed twenty- eight (28) consecutive days
from the date that performance was due.

respective directors, officers, employees, independent contractors who are
individuals and permitted assignees from and against all claims, demands,
suits, causes of action, obligations, liabilities, damages, losses and
judgments, costs and expenses, asserted against any of them by reason of any

the first Aircraft to FedEx, FedEx shall maintain until the [ * ]
anniversary of the Delivery Date of each Aircraft, with insurance carriers
reasonably acceptable to American, comprehensive airline liability insurance in

FedEx shall require its, or its successor's, hull insurers to waive any and all
rights of subrogation, set-off, counterclaim and deduction, whether by
attachment or otherwise, which they may have against the American Indemnitees,
for any loss, damage or destruction of the Aircraft.

interpretation of any provision in this Agreement or the performance by either
of them of their obligations under this Agreement (a "Dispute") without resort
to the courts. If any Dispute shall arise, American and FedEx agree to follow
the procedure set forth in this Article 13 (the "ADR Procedure") to resolve
such Dispute.

Section 13.02. Notice of Dispute. The Party believing a Dispute to
exist shall give the other Party written notice that the Dispute exists. Such
notice shall set forth in reasonable detail the facts alleged to give rise to
such Dispute, the provision or provisions of this Agreement giving rise to the
obligations implicated in the Dispute, the nature of any default claimed to
exist with respect to this Agreement and a statement of the manner in which
such Party believes the Dispute should be resolved. Within five (5) Business
Days after such notice is given the Party receiving such notice shall respond
in writing to the Party giving the notice. Such response (the "Response")
shall state whether the responding Party believes such Dispute exists, set
forth its view of the facts alleged to give rise to the Dispute and, if the
responding Party agrees that a Dispute exists, indicate what action the
responding Party believes should be taken with respect to the claim that a
Dispute exists.

Section 13.03. Dispute Resolution Through Negotiation. If the
Parties do not agree as to the action to be taken in resolution of the Dispute,
American and FedEx shall have a meeting no later than the fifth (5th) Business
Day following the date on which the Response is given. Such meeting shall be
held in the offices of the Party receiving the original notice of the Dispute
unless the Parties agree to meet elsewhere. Each of the Parties shall have in
attendance at such meeting an executive who shall have the authority to make
decisions and bind the Party he or she represents to any agreement that may be
made by the Parties at such meeting (a "Company Representative"), as well as
such other persons as the Parties may desire. At the meeting, the Parties
shall negotiate in good faith in an attempt to agree if a Dispute exists, upon
the exact nature of any Dispute agreed to exist, the manner in which any such
Dispute should be resolved and the date by which the resolution of any such
Dispute should be effected. If a resolution of such Dispute is not reached at
the initial meeting, before adjourning the meeting, the Parties shall determine
if an additional meeting or meetings should be held to negotiate further a
resolution of the Dispute. If American and FedEx determine an additional
meeting should be held, they shall agree to the time and place of such meeting.
Any agreement as to the resolution of such Dispute reached during such
negotiations shall be evidenced by a written agreement setting forth in
reasonable detail the actions that the Parties agree will be taken to resolve
or remedy the Dispute.

Section 13.04. Dispute Resolution Through Mediation. If American
and FedEx cannot resolve the Dispute pursuant to the procedure set forth in
Section 13.03 above (the "Negotiation Procedure") within ten (10) Business Days
after the first

-50-
<PAGE> 57
meeting held by the Parties pursuant to the Negotiation Procedure, American and
FedEx shall mediate the Dispute through a panel of three mediators (the
"Mediation Panel"). The Mediation Panel shall be appointed within ten (10)
Business Days after the date on which the Parties determine that they cannot
resolve the Dispute (the "Determination Date"). The Mediation Panel shall
consist of a professional mediator appointed by American, a professional
mediator appointed by FedEx and a professional mediator appointed by the two
mediators appointed by American and FedEx. When possible, each mediator shall
be familiar with the aircraft industry. The mediation shall take place on the
fifteenth (15th) Business Day after the Determination Date or such earlier
date as the Parties and the Mediation Panel may agree. Each Party shall
prepare and submit to the Mediation Panel at least two (2) Business Days before
the mediation occurs, written submissions setting forth their respective
positions with respect to the Dispute. Each Party shall send a Company
Representative and such other persons, including professional advisors, as they
desire to such mediation. The Parties agree to work in good faith to reach an
agreement settling the Dispute at the mediation. Any agreement as to the
resolution of such Dispute reached during such mediation shall be evidenced by
a written agreement setting forth in reasonable detail the actions that the
Parties agree will be taken to resolve the Dispute. The mediation shall be
deemed unsuccessful if so declared by the Mediation Panel.

Section 13.05. Dispute Resolution Through Arbitration. American and
FedEx agree that if they cannot resolve the Dispute pursuant to the Negotiation
Procedure or mediation as described in Section 13.04 above (the "Mediation")
within ten (10) Business Days after the commencement of the first meeting of
the Parties with the Mediation Panel, they will submit the Dispute to binding
arbitration (the "Arbitration") pursuant to the New York Arbitration Statute
and the American Arbitration Association's (the "AAA") Commercial Arbitration
Rules as in effect at the time of the submission of the Dispute to the AAA (the
"CAR"). American and FedEx shall submit the Dispute to the AAA for binding
arbitration within five (5) Business Days after the unsuccessful conclusion of
the Mediation Process. The arbitration shall take place (i) in Dallas, Texas
or such other place as American, FedEx and the arbitrators assigned to the case
shall agree and (ii) on such date and at such time as the arbitrators shall
establish. The Dispute shall be arbitrated by a panel of three arbitrators
(the "Panel") who shall, if possible, each be experienced in the aircraft
industry and who shall be chosen in accordance with the CAR. The Panel shall
issue a reasoned decision and award of damages, specific performance or
injunction. American and FedEx agree to abide by and perform any award
rendered by the Panel. American and FedEx intend that the Dispute will be
resolved by application of the laws of the State of New York and that the
Panel's authority to make any award in the arbitration of the Dispute shall be
based on and limited by the laws of the State of New York, the terms and
conditions of this Agreement and the CAR. The Panel's determination of facts
shall be final and binding on American and FedEx if there is substantial
evidence in the record of such arbitration to support such determination, it
being the intention of the Parties

-51-
<PAGE> 58
that the standard for any judicial review of the findings or award of the Panel
be the same standard as applies in the case of appeals to actions of
administrative agencies in the State of New York. Judgment on the award in the
arbitration may be entered by any court having jurisdiction of the Dispute.
Subject to the CAR, the Parties will endeavor in good faith to conclude the
arbitration by no later than thirty (30) Business Days after it commences.

Section 13.06. Forbearance During Resolution Process. American and
FedEx agree to forbear from pursuing any remedy under this Agreement or
otherwise available under law, including the institution of any lawsuit, while
the ADR Procedure is in operation with respect to any Dispute.

Section 13.07. Limitation of Remedies. American and FedEx agree
that, notwithstanding anything to the contrary herein, in the laws of the State
of New York, Tennessee or Texas or the CAR, the result of any agreement reached
by them in the Mediation or any award made by the Arbitration Panel in the
Arbitration shall be consistent with the terms and conditions of this Agreement
and that any award shall be only a remedy that would available to a Party to
this Agreement as a result of a breach of this Agreement had the ADR Procedure
not been in effect. IN NO EVENT SHALL THE PANEL AWARD ANY INDIRECT,
INCIDENTAL, CONSEQUENTIAL, PUNITIVE, SPECIAL, EXEMPLARY OR OTHER THAN DIRECT
DAMAGES.

Section 13.08. Expenses. Each of American and FedEx shall pay its
own out-of-pocket expenses in connection with the conduct of the ADR Procedure
as to any Dispute. The costs and expenses of any Mediation, other than
American's and FedEx's out-of-pocket expenses in connection therewith, shall be
borne equally by American and FedEx. The costs and expenses of any
Arbitration, other than American's and FedEx's out-of-pocket expenses in
connection therewith, shall be payable in accordance with the CAR.

and FedEx agrees to keep the economic terms of this Agreement confidential and
not to disclose, transfer, use or otherwise make available such information to
any third party without the prior written consent of the other Party. Each of
American and FedEx agrees to exercise care that is at least equal to the care

and FedEx may disclose confidential information to their respective officers,
directors, employees and/or tax, legal and other professional advisors who are

<PAGE> 61
Service or a state taxing authority for information). In the event of a breach
of or a default under the terms of this Section 15.01, the non-breaching Party

FURTHER ASSURANCES

Section 16.01. Further Assurances. (a) American recognizes that in
the course of (i) the conversion of the Aircraft from a passenger configuration
to a cargo configuration and (ii) the transition of the Aircraft from the
American Program to FedEx's FAA-approved maintenance program, issues will arise
in which American may possess information and expertise regarding the Aircraft
that FedEx would find useful, Aircraft Records or Engine Records that may be
necessary to the transition of the Aircraft to FedEx's maintenance program, and

and locations to discuss the Aircraft and American's maintenance of the
Aircraft. In no event shall the assistance to be provided by American to FedEx
require the incurrence by American of more than nominal expense.

(b) American will provide to FedEx a supplemental type certificate (a
"STC") and the substantiating data covering any modification of an Aircraft
that is delivered to FedEx by American pursuant to this Agreement if that
modification is designed by American. FedEx may use such STC to make the same
