4.   DEVELOPMENT

     4.1    INITIAL DEVELOPMENT SERVICES.

            (a)     Specifications.

                    (i)     Orbitz will provide AA with (A) Specifications for
the Core Functionality identified in Exhibit B that will be available on the
Delivery Date and (B) dedicated resources to assist AA in determining the
AA-Specific Functionality necessary to implement the Orbitz Software. AA will
thereafter provide Orbitz with a definitive list of the requested Deliverables,
along with any Requirements therefor, within any time period set forth in the
Schedule.

                    (ii)    Orbitz will,  within the time period set forth in
the Schedule, review the Requirements described in the preceding subsection and
provide AA with (A) Specifications for the Deliverables, (B) a Not-To-Exceed Fee
Estimate for the development of any requested AA-Specific Functionality, and (C)
a non-binding fee estimate for the development of any requested AA-Competitive
Functionality. The Specifications will include procedures for developing
mutually acceptable, objective criteria for testing the Deliverables and any
applicable requirements specifying the physical locations where development will
occur.

                    (iii)   Following receipt of the Specifications, the
Not-To-Exceed Fee Estimate and the non-binding fee estimate described in the
preceding subsection, within the time period set forth in the Schedule AA will
provide Orbitz with written verification of which portions of the Deliverables
AA requests that Orbitz develop. Thereafter, AA and Orbitz will use reasonable
commercial efforts to agree upon the prioritization of the functionality to be
included in the Deliverables by the date set forth in the Schedule, including
the Core Functionality, the AA-Specific Functionality, and any other Initial
Development Services.

            (b)     Deliverables. Upon the parties' mutual agreement of the
prioritization of the Specifications in accordance with Section 4.1(a)(iii),
Orbitz will provide AA with dedicated resources to support the development of
the Deliverables. Orbitz will develop the Deliverables requested by AA in
accordance with the development milestone dates set forth in the Schedule.
Sabre-Specific Code will be considered AA-Specific Functionality, for which AA
will pay any applicable License and Development Fees in accordance with this
Agreement; provided, however, that at such time that Orbitz makes Sabre-Specific
Code available to, or uses Sabre-Specific Code for the benefit of, any
Competitor hosted in a Sabre GDS, any subsequent development of Sabre-Specific
Code will be considered Core Functionality, the development of which is not
chargeable to AA. When Orbitz has satisfactorily completed coding and

                  CONFIDENTIAL                            Page 5
<Page>

testing of the Deliverables, Orbitz will: (i) notify AA, (ii) provide the Orbitz
test results to AA, and (iii) make such Deliverables available to AA for
acceptance testing.

     4.2    FUTURE DEVELOPMENT SERVICES. Subject to Section 4.8, after the
Launch Date, AA may from time to time during the Term request that Orbitz
develop additional AA-Specific Functionality by submitting a Statement of
Services listing the requested AA-Specific Functionality and any Requirements
therefor. Orbitz will promptly review such Requirements and provide AA with (a)
Specifications for such AA-Specific Functionality; (b) a Not-To-Exceed Fee
Estimate for the development of such AA-Specific Functionality, including a
non-binding fee estimate for the development of any AA-Competitive
Functionality; (c) in the event Orbitz does not agree to designate any requested
AA-Competitive Functionality as such, a written statement indicating such
denial; and (d) an estimated timetable for commencement and completion of such
additional AA-Specific Functionality (collectively, the "Estimate"). Orbitz will
use commercially reasonable efforts to ensure that the Estimate is based on
assumptions and data that are realistic, reasonable and attainable. The
Specifications will include procedures for developing mutually acceptable,
objective criteria for testing the AA-Specific Functionality and any applicable
Requirements specifying the physical locations where development will occur. In
the event AA elects to proceed with such development in accordance with the
Estimate, Orbitz will take all reasonable steps to make available to AA
sufficient resources to fulfill the request. In the event any aspect of the
Estimate is not reasonably suitable to AA, Orbitz will allow AA to fund
dedicated Orbitz resources to fulfill such request, with such efforts being
provided at the rates set forth in Section 6.1(b) of this Agreement, provided
that such funding commitment is for a duration of not less than six months for
each such dedicated resource.

     4.3    ACCEPTANCE TESTING.

            (a)     Following receipt of Orbitz's notice that a Deliverable is
ready for acceptance testing, AA will test the Deliverable within the time
period set forth in the Schedule (the "Test Period") to determine whether the
Deliverable substantially conforms to the Specifications. AA's acceptance
testing will include unit testing, system testing within the total Orbitz
Software solution, and AA.com site integration testing. If AA determines after
such acceptance testing that a Deliverable substantially conforms to the
Specifications, AA will accept such Deliverable and provide Orbitz with notice
that the Deliverable is accepted. Acceptance of a Deliverable will occur on the
later to occur of (i) the date AA successfully completes acceptance tests
demonstrating that the Deliverable substantially conforms to the acceptance
criteria specified in the applicable Statement of Services and AA issues a
written notice of acceptance, or (ii) ten days after the end of the Test Period.

            (b)     If a Deliverable fails to substantially conform to the
Specifications, AA will provide Orbitz with a written report of the
non-conformity, within ten days after the end of the Test Period, specifying
such non-conformity in reasonable detail. Upon receipt of a non-conformity
report, Orbitz will either correct and resubmit the Deliverable for re-testing
within ten days of AA's notice of non-conformance, or as otherwise set forth in
the Schedule or, if Orbitz reasonably believes that such reported non-conformity
is actually a modification from the agreed upon Specifications, Orbitz will
notify AA that such reported non-conformity is actually a Change Request, to be
handled pursuant to Section 7. In the event that a Deliverable fails to pass
acceptance testing and the failure is due to causes outside the control of
Orbitz, Orbitz agrees to use its commercially reasonable efforts to make its
personnel available to provide assistance to help resolve the problem; such
assistance to be chargeable as Initial Development Services.

     4.4    FAILURE TO DELIVER CONFORMING SOFTWARE. In the event that Orbitz
fails to deliver Deliverables substantially in conformance with the
Specifications, including the Requirements, within 30 days of the Delivery Date,
then AA will not be charged for any development efforts performed by Orbitz or
its Subcontractors following such 30 day period with respect to that
non-conforming Deliverable. In the event that Orbitz fails to deliver
Deliverables that are substantially in conformance with the Specifications
within 90 days of the Delivery Date, AA will have the option, at its sole
discretion, to either (a) terminate this Agreement, receive a refund of all the
License and Development Fees paid to Orbitz and be released from any further
payment obligation under this Agreement, including payment of the remaining

Fixed Hosting and Support Fee described in Section 6.2; (b) issue a partial
acceptance of the Deliverables and obtain a refund of any portion of the License
and Development Fees previously paid for any rejected Deliverables, including
fees paid for any other previously accepted Deliverables rendered unusable due
to the rejected Deliverables; or (c) extend the Delivery Date while reserving
its right to revoke acceptance pursuant to options (a) and (b) above if
corrections to the defective Deliverables are not completed in a timely manner.
In the event AA elects to issue a "partial acceptance" or extends the Delivery
Date pursuant to (b) or (c) above, AA will not be charged for any subsequent
development services performed by Orbitz or its Subcontractors required to
complete such Deliverables. The remedies available to AA under this Section 4.4
will only apply to the extent that AA, including its subcontractors, has not
caused or contributed to the delay.

is required under any Specifications, the parties acknowledge that Orbitz's
obligations to develop such connectivity interface is expressly dependent upon
the cooperation of Sabre and AA. Any such development, to the extent performed
by Orbitz, will be deemed AA-Specific Functionality for purposes of this
Agreement, and Orbitz will be solely responsible for the maintenance, support
and operation of such development. AA will provide Orbitz with any and all
information and assistance reasonably requested by Orbitz to develop and
maintain a connectivity interface with Sabre. Orbitz agrees that it will use
commercially reasonable efforts to cooperate with Sabre for all purposes in
connection with this Agreement. Orbitz will not be responsible for any delay or
failure to meet the Service Level Commitments specified in Exhibit F to the
extent such delay or failure is (a) caused by or related to AA's or Sabre's
failure to cooperate with Orbitz or to provide the information and assistance
that Orbitz may reasonably request to develop and maintain the connectivity
interface with Sabre, or (b) caused by or related to a failure in the Sabre
system.

     4.7    LIMITATION. Orbitz will have no obligation to develop or provide any
functionality (including without limitation, coding rules or logic) with respect
to the Orbitz Software or the connectivity interface which is not specifically
requested by AA or included in any Statement of Services, Specification or
Change Order in accordance with this Agreement.

     4.8    FURTHER DEVELOPMENT. Each party agrees that development of an
ongoing enhancement prioritization process is necessary to ensure that AA
receives the requisite resources should any Competitor select an Orbitz
solution. After the Delivery Date or upon completion of the Initial Development,
whichever is later, Orbitz will provide development services to AA pursuant to
the change control procedures set forth in Section 7. Any such subsequent
development of additional AA-Specific Functionality is outside the scope of
Orbitz's Hosting and Support Services obligations, and any such requests will be
handled as a new Statement of Services or as a Change Request pursuant to
Section 7.

     4.9    ATTRIBUTION. Nothing in this Agreement will be deemed to require AA
to provide attribution for Orbitz or any third party with respect to the Orbitz
Software.

Orbitz Software on servers located in Orbitz's primary hosting facility, unless
AA approves or agrees to hosting in another location.

     5.2    SERVICE LEVELS. Orbitz will meet or exceed the service levels set
forth in Exhibit F related to the Orbitz Software and performance of the Hosting
and Support Services (the "Service Level Agreement"). AA will use commercially
reasonable efforts to provide Orbitz with at least 24 hours advance notification
of any marketing events that are expected to create an unseasonably high spike
in the number of booking transactions. Orbitz will satisfy all reasonable
requests by AA for information AA requires to properly evaluate the performance
of Orbitz under this Agreement, including validating Orbitz's compliance with
Exhibit F.

     5.3    SUPPORT. AA will perform all customer service related to, and will
be responsible for the fulfillment of, all bookings made through the Website.
Orbitz will provide second and third level technical support for the Orbitz

will use commercially reasonable efforts to provide such Updates to AA within 30
days of Orbitz's general release thereof. Such Updates will include third party
licensor functionality incorporated into the Orbitz Software, to the extent
permitted by Orbitz's agreements with its licensors. Notwithstanding the
foregoing, in no event will AA be charged an additional fee for such Updates,
unless otherwise agreed by AA. AA will have the right to refuse, or delay
implementation of, any Updates if such Updates: (a) involve an additional third
party license fee; (b) have been observed to cause performance problems or
degradation; or (c) will cause AA to incur additional indirect costs (such as
for related user interfaces) in order to implement the Update. If AA elects not
to implement an Update pursuant to the preceding sentence, Orbitz will continue
to provide support as described in Section 5.3 for the then currently installed
version of the Orbitz Software. Orbitz will use commercially reasonable efforts
to develop and release any Updates that are reasonably requested by AA to keep
the air transportation booking aspects of the Core Functionality competitive
with, and comparable to, similar products in the marketplace.

     5.5    OUT-OF-SCOPE SERVICES. Orbitz is not responsible for profile
databases, Website presentation or design, ITA pricing services, shared use of
other Orbitz partnerships, non-air functionality, customer service (unless
otherwise agreed by the parties in writing), fulfillment, or any and all other

not include the ITA pricing engine and is for air transportation bookings only.
In the event that AA obtains a license to the ITA pricing engine from ITA,
Orbitz will provide AA with support to implement such functionality into the
Orbitz Software. Any such support will be provided as a Change Request pursuant
to Section 7, and the fee for such support will be calculated using Orbitz's
Labor Rate. AA will negotiate the requisite license directly with ITA for such
functionality, or such other future third party licensor, as the case may be.

6.   FEES AND PAYMENT

     6.1    LICENSE AND DEVELOPMENT FEES.

            (a)     Initial Development Services. In consideration for the
licenses granted by Orbitz hereunder and the Services related to development of
the AA-Specific Functionality and AA-Competitive Functionality as part of the
Initial Development Services performed by Orbitz personnel, AA will pay Orbitz a
fee (the "License and Development Fee") for such Initial Development Services at
the agreed upon rate of $[***], whether such Initial Development Services were
performed prior to or after the Effective Date.

    with the Commission. Confidential treatment has been requested with
    respect to the omitted portions.

<Page>

            (b)     Future Development Services. The License and Development Fee
for Services related to development of AA-Specific Functionality (other than
AA-Competitive Functionality) as part of the Future Development Services
performed by Orbitz personnel will be calculated using Orbitz's Labor Rate. The
License and Development Fee for Services related to development of AA
Competitive Functionality as part of the Future Development Services performed
by Orbitz personnel will be calculated using the then current market rates, as
determined by the parties based upon rates then being charged by Orbitz or its
Subcontractor (as the case may be) for similar services. AA will also reimburse
Orbitz the actual costs (without markup) incurred for any third party
professional services; provided, however, that Orbitz will notify AA of such
third party rates in advance of performance of such services.

     6.2    FIXED HOSTING AND SUPPORT FEES. Following the Launch Date, Orbitz
will perform the Hosting and Support Services for an annual Fixed Hosting and
Support Fee, as set forth in Exhibit D.

     6.3    FIXED HOSTING AND SUPPORT FEE CHANGES.

            (a)     In the event that either (i) the United States Department of
Justice or the Department of Transportation initiate formal proceedings against
Orbitz that result in the entry of a final, non-appealable judgment, or (ii)
Orbitz enters into an agreement or consent decree with either such Department,
that prohibits or restricts Orbitz' operation of its online booking site and
such prohibition or restriction is reasonably expected to impact Orbitz' ability
to host the Orbitz Software as contemplated by this Agreement, then AA will have
the option to host, or engage a third party to host, the Orbitz Software without
changing the other obligations of Orbitz set forth herein. In such event, the
annual Fixed Hosting and Support Fee will be reduced by the cost incurred by AA
to host, and establish and maintain the connectivity required to host, the
Orbitz Software for each year (or portion thereof) remaining in the Term.

            (b)     The parties acknowledge and agree that the pricing
offered by Orbitz herein is based on AA's current and projected booking
transaction volumes, based on internally generated growth. In the event that
AA is a party, directly or indirectly, to (i) a merger, (ii) an acquisition
of all or substantially all of the assets of a third party, (iii) an
acquisition of the majority of the issued and outstanding voting stock of a
third party by AA, or (iv) the acquisition of assets of a third party by AA,
the result of any of which is an increase in AA's operations by more than
[***]% (each, an "Acquisition Transaction"), and such Acquisition Transaction
is reasonably expected to result in a Booked Volume Increase (as defined in
Section 6.3(f)) of more than [***]%, then the annual Fixed Hosting and Support
Fee will be increased (the "Fixed Hosting and Support Fee Increase") by an
amount equal to (x) the increase in costs incurred by Orbitz due solely to
the Booked Volume Increase, plus (y) [***]% of such costs; provided, however,
that the Fixed Hosting and Support Fee Increase will not exceed an amount
equal to the Booked Volume Increase percentage times the then current annual
Fixed Hosting and Support Fee. One-twelfth (1/12) of the Fixed Hosting and
Support Fee Increase will be added for each month remaining in the then
current year of the Agreement, and for each subsequent year during the Term,
to be effective as of the Cut-over Date and payable in accordance with the
Fixed Hosting and Support Fee schedule.

            (c)     (Intentionally left blank).

            (d)     In the event that AA experiences, directly or indirectly,
(i) a merger or divestiture of substantially all of the assets of AA (defined
as 30% or more of its operations), or (ii) divestiture of the majority of the
issued and outstanding voting stock of AA (each, a "Divestiture Transaction")
that is reasonably expected to result in a Booked Volume Decrease (as defined
in Section 6.3(f)) of more than [***]%, then the annual Fixed Hosting and
Support Fee will be decreased by an amount (the "Fixed Hosting and Support
Fee Decrease") equal to the amount of such Booked Volume Decrease times the
then-current Hosting and Support Fee (the "Hosting and Support Fee
Decrease"); provided, however, that if Orbitz can establish that the costs
incurred by Orbitz solely in connection with the Booked Volume Decrease will
decrease by an amount (the "Cost Decrease") less than the Hosting and Support
Fee Decrease, then the "Hosting and Support Fee Decrease will equal the Cost
Decrease; provided, further, that in any event, the Hosting and Support Fee
Decrease will not exceed the value of the Booked Volume Decrease percentage
applied to then current Hosting and Support Fee. One-twelfth of the Fixed

*** Certain information on this page has been omitted and filed separately
    with the Commission. Confidential treatment has been requested with
    respect to the omitted portions.

<Page>

Hosting and Support Fee Decrease will be subtracted for each month remaining in
the then current year of the Agreement and for each subsequent year during the
Term, to be effective as of the Cut-over Date.

            (e)     In the event that Datalex Software is not used by Orbitz to
provide the Initial Development Services or Hosting and Support Services, the
annual Fixed Hosting and Support Fee will be reduced by $[***] for each year
(or portion thereof) remaining in the Term. In the event that any Datalex
Software is used by Orbitz to provide the Initial Development Services or
Hosting and Support Services, and the sublicense fee paid by Orbitz to Datalex
is less than $[***], then the annual Fixed Hosting and Support Fee will be
reduced by the amount of such fee reduction.

            (f)     For purposes of this Section 6.3, "Booked Volume Increase"
or "Booked Volume Decrease," will be calculated as (i) the difference between
AA.com's average monthly Transactions during the first 90 days following the
Cut-over Date and AA.com's average monthly Transactions during the 90 days
immediately preceding the Cut-over Date, divided by (ii) AA.com's average
monthly Transactions during the 90 days immediately preceding the Cut-over Date.

            (g)     In the event that Orbitz, as the result of any cause other
than superseding law or regulation, or court or government agency order,
discontinues hosting, maintenance and/or support of the Orbitz Software, (i) the
Fixed Hosting and Support Fee will thereafter be reduced by the greater of (A)
the amounts shown on the following table, or (B) an amount equal to the cost
incurred by AA to secure comparable replacement services, and (ii) Orbitz will
refund to AA a prorated portion of the then-current quarter's Fixed Hosting and
Support Fee, with such proration equal to one-twelfth of the reduced amount
described in the foregoing clause, multiplied by the number of months remaining
in the then-current contract quarter:

</Table>

     6.4    REIMBURSABLE EXPENSES. AA will reimburse Orbitz at cost for the
reasonable, pre-approved travel and lodging and related out-of-pocket expenses
that Orbitz or its Subcontractors may incur in performing the Services (the
"Reimbursable Expenses"). Orbitz or its Subcontractors will use travel
authorization certificates (TACs) for air transportation whenever possible.
Orbitz will furnish AA with appropriate receipts for all Reimbursable Expenses.

     6.5    PAYMENT TERMS. The annual Fixed Hosting and Support Fee will be
invoiced in four equal installments at the beginning of each calendar quarter
following the Launch Date. At Orbitz's option, the first installment payment
(the "Initial Installment") may be invoiced in advance of the Launch Date on the
date when the production environment is fully prepared for testing by AA, but no
earlier than November 15, 2001; provided, however, that in such event all
subsequent installments will be invoiced and payable as set forth above starting
with the beginning of the second calendar quarter following the Launch Date.
License and Development Fees and Reimbursable Expenses will be invoiced monthly.
AA will pay all undisputed invoices within 30 days of receipt of a correct
invoice. In the event that AA asserts in good faith that any item or items on an
invoice are not correct, then AA will within 30 days of receipt of such invoice
(i) deliver written notice to Orbitz explaining in detail why AA believes that
an item or items are not correct and (ii) pay to Orbitz all amounts on the
invoice that are not the subject of a good faith dispute by AA.

     6.6    TAXES.

            (a)     The License and Development Fees, Fixed Hosting and Support
Fees, and Reimbursable Expenses are exclusive of all sales, services or other
taxes that Orbitz may be legally obligated to charge AA for performing the
Services, and AA will promptly pay, or reimburse Orbitz for the payment of, any
and all such taxes that may be due or payable. Orbitz will honor any tax-exempt
certificates provided by AA.

            (b)     AA will not be liable for the payment or reimbursement to
Orbitz of any franchise taxes or fees, or any taxes measured by or against
Orbitz's income or property. AA will not withhold taxes or Social Security
payments from any sum paid to Orbitz under this Agreement. Orbitz acknowledges
and agrees that Orbitz is solely responsible for the payment of its federal,
state and local employment taxes. Orbitz agrees to indemnify AA for all tax
liability described in this Section 6.6(b), including interest and penalties, if
any.

     6.7    MOST FAVORED CUSTOMER. During the Term, the financial terms of this
Agreement will be at least as favorable or more favorable than the financial
terms of any other current or prospective Orbitz customer that engages Orbitz
for a project that is substantially similar to the engagement contemplated
herein. The determination of what is and is not "substantially similar" will be
based on relevant factors such as scope of project, volume of transactions,
amount of integration and custom development work required, and pricing model.
Any change in financial terms pursuant to this clause will only be applied on a
prospective basis, effective as of the effective date of such other customer's
agreement with Orbitz, whether such agreement is effective before or after the
Effective Date.

     6.8    REPORTING; AUDIT. Orbitz will create and maintain accurate records
with respect to its performance under this Agreement, including without
limitation the number and substance of all Transactions and the calculation of
the Monthly System Availability. Orbitz will maintain such records during the
Term and for one year following any expiration or termination of this Agreement.
Within five days following the end of each applicable month, Orbitz provide AA
with written reports of such information, which reports will be in such detail
as may be reasonably requested by AA from time to time, including without
limitation detail as to the number and substance of all Transactions (with a
breakdown of new PNRs and modified PNRs) and Monthly System Availability. AA
will have the right, upon not less than five days prior notice, to conduct an
audit of the Transaction information included in such monthly reports. If such
an audit reveals that any of Orbitz's reports submitted overstated amounts owed
by AA, then Orbitz shall pay to AA, within 30 days following the conclusion of
such audit, the amount of any such overpayments.

7.   CHANGE REQUESTS

     7.1    CHANGE REQUEST. If either party wants to request a modification,
addition or replacement of the Orbitz Software (including, but not limited to,
the Core Functionality and the AA-Specific Functionality) or the Hosting and
Support Services, that party's Relationship Manager will submit a completed
Change Request to the Relationship Manager of the other party. The Change
Request will adequately describe (a) the requested modification, (b) the
estimated resources required to implement the modification, (c) its impact on
the Schedule, (d) its impact, if any, resulting in an increase or decrease to
the License and Development Fees and/or the Fixed Hosting and Support Fees and
(e) its impact on the maintenance requirements of the Orbitz Software.

     7.2    CHANGE ACCEPTANCE. Upon receipt of a completed Change Request, the
recipient Relationship Manager will either (a) expressly accept the proposed
modification without qualification within 5 days after its receipt or (b) defer
the request for discussion of the next scheduled or emergency status meeting.
The Relationship Managers will use reasonable commercial efforts to resolve any
deferred proposed modification expeditiously. No proposed Change Request will be
effective unless expressly accepted by the primary or alternate Relationship
Managers of both parties. If so accepted, the Change Request will be executed by
the Relationship Managers of both parties and will then constitute a formal
amendment of this Agreement.

8.   CONFIDENTIALITY

     The following provisions shall supplement the terms of that certain
Non-Disclosure Agreement that was attached as Exhibit C to the Letter of Intent
between AA and Orbitz executed in April 2001 (the "NDA"), a copy of which is
attached as Exhibit G to this Agreement and incorporated by reference herein.
The NDA shall continue to be in full force and effect during the term of this
Agreement:

     8.1    PROTECTION OF CONFIDENTIAL INFORMATION. Each party agrees to
maintain strict confidentiality regarding the subject matter of this Agreement,
in accordance with the NDA. Each party will take such measures that are
necessary to protect against the disclosure or use of the Confidential
Information of the other party as it takes to protect its own proprietary or
confidential information (but in any case no less than reasonable measures).
Each party agrees that the other party will have no adequate remedy at law if
there is a breach or threatened breach of this Section 8 or the NDA and,
accordingly, that either party will be entitled (in addition to any legal or
equitable remedies available to such party) to injunctive or other equitable
relief to prevent or remedy such breach.

     8.2    RESTRICTIONS ON DISCLOSURE AND USE. Notwithstanding anything
contained in the NDA, Orbitz will not disclose any Confidential Information
provided to it by AA, including the terms and conditions of this Agreement and
any advanced fare information provided under Section 5.2 of this Agreement or
otherwise, to any equity owners or principals of Orbitz that are employed by a
Competitor of AA except to the extent required by the laws of the State of
Delaware and/or the Orbitz LLC Agreement dated May 9, 2000 (formerly the "DUNC
LLC Agreement"). In the event such disclosure is required pursuant to the laws
of the State of Delaware, Orbitz will provide advance notice to the Vice
President of Customer Technology at AA and provide AA sufficient time to contest
the need for such disclosure prior to making such disclosure. In the event
disclosure is required pursuant to the Orbitz LLC Agreement, Orbitz will provide
advance notice to, and obtain written approval of such disclosure from, the Vice
President of Customer Technology at AA, which approval will not be unreasonably
withheld.

9.   PROPRIETARY RIGHTS

     9.1    OWNERSHIP.

            (a)     As between AA and Orbitz, and to the extent of Orbitz's
prior ownership rights, AA acknowledges that Orbitz will own all patents
(including any business process patents), rights to file for patents,
inventions, copyrights, trademarks, trade secrets and all other right, title and
interest (including any renewals or extensions) in or to the Orbitz Software,
including the AA-Specific Functionality (but excluding the AA-Competitive
Functionality) developed by Orbitz or its employees or Subcontractors during the
performance of this Agreement and any derivative works thereof created by
Orbitz. AA hereby assigns and agrees to assign, and will cause its
Subcontractors to assign, to Orbitz all rights that AA may have or acquire in or
to such works for no additional consideration. No other person will acquire or
retain any rights in or to such works, unless Orbitz otherwise agrees on a
case-by-case basis. At Orbitz's request and expense, AA will cause the execution
of the instruments that may be appropriate to give full legal effect to this
Section for no additional consideration. Orbitz will not subcontract with a
third party developer granting any ownership rights to any AA-Specific
Functionality that would in any way impair AA's ability to have and enjoy full
use of the licenses and rights granted to AA under this Agreement.

            (b)     Orbitz acknowledges and agrees that it will develop the
AA-Competitive Functionality for AA as a "work-made-for-hire" and that AA will
own the copyright in or to the AA-Competitive Functionality, upon payment to
Orbitz of the applicable License and Development Fees for such AA-Competitive
Functionality. As between Orbitz and AA, Orbitz acknowledges that AA will own
all trademarks, trade secrets and all other right, title and interest (including
any renewals or extensions), excluding patent rights, in or to the
AA-Competitive Functionality and any derivative works thereof created by Orbitz.
Orbitz hereby assigns and agrees to assign, and will cause its Subcontractors to
assign, to AA for no additional consideration all rights that Orbitz may have or
acquires in or to such works. No other person will acquire or retain any rights
in or to such works, unless AA otherwise agrees on a case-by-case basis. At AA's
request and expense and for no additional consideration, Orbitz will cause the

                  CONFIDENTIAL                            Page 12
<Page>

execution of the instruments that may be appropriate to give full legal effect
to this Section for no additional consideration. Each party agrees that it will
not file a patent application with respect to the AA-Competitive Functionality
or any derivative works thereof without the written consent of the other party.

     9.2    LICENSE TO AA.

            (a)     Upon AA's Acceptance of any Orbitz Software, Orbitz grants
AA the limited, paid-up, non-exclusive, non-transferable, royalty-free,
worldwide right, effective during the Term, to access and use (and permit its
customers to access and use) such Orbitz Software (other than the AA-Competitive
Functionality, which will be owned by AA in accordance with Section 9.1 of this
Agreement) on the terms and conditions set forth in this Agreement. AA
acknowledges and agrees that any access and use by its customers will be subject
to the terms and conditions posted to the Website, which will include
protections for Orbitz at least as protective as the terms and conditions that
AA posts on the Website to protect its own rights, limit its liability, and
disclaim forms of damages. AA will not display or use the Orbitz Software as
part of any third party site or service.

            (b)     Upon AA's Acceptance of the AA-Specific Functionality (other
than AA-Competitive Functionality, which will be owned by AA in accordance with
Section 9.1 of this Agreement), Orbitz grants AA the perpetual, royalty-free,
worldwide right to access and use such AA-Specific Functionality, in both source
and object code forms, for AA's ordinary and customary business purposes;
provided, however, that AA will not have the right to market or distribute the
AA-Specific Functionality to any third party.

            (c)     During the Term of this Agreement, AA may access and use
(and allow its customers to use) the Orbitz Software licensed hereunder to
search, view, reserve and/or purchase travel-related products and services
offered by AA, its Affiliates, Airline Partners and other air transportation
companies in accordance with the terms and conditions set forth in this
Agreement.

            (d)     Agents of AA who are under contract with AA to provide
outsourcing services, including, but not limited to, providing application
development services, data processing or other transactional services for the
benefit of AA and/or its Affiliates and Airline Partners, are authorized to
access and use the Orbitz Software in accordance with the terms and conditions
set forth in this Agreement.

            (e)     At the expiration or termination of this Agreement, AA
will have the option to purchase from Orbitz, and Orbitz agrees to grant to
AA, a perpetual, non-exclusive license to the compiled and object code for
the Orbitz Software (including the related Documentation) for a [***] fee
[***]. In the event that the parties are unable to agree on such fee after a
period of 30 days, the parties will jointly apply to and pay for an
independent third party through the Information Technology Association of
America to determine such fee and the determination of such third party will
be final and binding on the parties, provided, however, that AA will be under
no obligation to effectuate the acquisition. If AA elects not to exercise its
option to purchase a license to the Orbitz owned software, AA will be
responsible for the full payment of the fee associated with such independent
third party. If AA decides to exercise its option to purchase a license to
the Orbitz Software, such purchase will be at the price [***]. After such
acquisition, AA will have the right to host and use the Orbitz Software
thereafter in accordance with subsection 9.2(d) of this Agreement.

     9.3    LICENSE TO ORBITZ. Effective during the Term, AA hereby grants
Orbitz the non-exclusive, non-transferable, royalty-free, world-wide right to
(a) use the AA Information solely to perform its obligations under this
Agreement; (b) use aggregated customer data derived from the Website bookings
for internal site management purposes, provided that Orbitz will not use or
disclose such customer data for customer tracking or any other purposes
whatsoever; and (c) use, host and display the AA-Competitive Functionality only
to provide the Hosting and Support Services to AA and to modify and adapt the
AA-Competitive Functionality for AA in accordance with this Agreement, either
directly or through Subcontractors.

10.  ESCROW

     10.1   ESCROWED MATERIALS. No later than 60 days after the Effective Date,
and within 30 days after release of each Update, Orbitz will deliver to Fort
Knox Escrow Services, as escrow agent, the following: (a) a copy of the current,
fully commented version of the source code of the latest release of the Orbitz
Software that Orbitz owns, (b) the available Documentation related thereto, and
(c) reproducible binary masters of the latest release of the Orbitz Software
(collectively, "Escrowed Material"). A copy of the Escrow Agreement between
Orbitz and Fort Knox Escrow Services related to the Escrowed Materials will be
attached hereto as Exhibit H upon execution.

     10.2   MAINTENANCE. Orbitz will replace the source code of the Orbitz
Software in the event of a media defect. The nature and completeness of the
Escrowed Materials will be subject to verification by a representative of AA
only at the facilities of the escrow agent in the presence of a representative
of Orbitz. AA may not make any copies, in whole or in part, of the Escrowed
Material, and all such material will be considered to be Confidential
Information regardless of whether they have been marked "confidential". All
expenses associated with establishing and maintaining the Escrowed Materials
will be shared equally between AA and Orbitz.

     10.3   RELEASE CONDITION. If Orbitz (a) generally discontinues hosting,
maintenance and/or support of the Orbitz Software, (b) is in material, uncured
breach of its maintenance and support obligations to the extent that it is in
breach of its support standard commitments for Severity 1 or Severity 2,
including those defined as a "Material Service Level Failure" in Exhibit F, or
(c) is insolvent, files a petition in bankruptcy or has such a petition filed
against it (and fails to lift any stay imposed thereby within 60 days after such
stay becomes effective), has a receiver appointed with respect to all or
substantially all of its assets, makes an assignment for the benefit of
creditors, or ceases to do business in the ordinary course, then AA may demand
the release of the Escrowed Material by simultaneously sending the escrow agent,
with a copy to Orbitz, a written demand for the Escrowed Material by overnight
courier. Orbitz will cause the escrow agent to release the Escrowed Material to
AA within five business days after Orbitz's receipt of the demand notice unless
Orbitz has notified the escrow agent and AA that it disputes that a release
condition has occurred within such five-day period. If Orbitz has not provided
AA with material information within ten days of Orbitz's notification to the
escrow agent which establishes that none of the release conditions set forth
above have occurred, Orbitz's dispute will be deemed withdrawn and the escrow
agent will release the Escrowed Material to AA.

     10.4   RIGHTS. In the event the Escrowed Material is released to AA, Orbitz
grants to AA a fully paid up license to use and modify the Escrowed Material
solely to maintain and support the Orbitz Software in accordance with the terms
of this Agreement and for no other purpose. AA will maintain the Escrowed
Material on a secure system with access limited to only those persons necessary
to maintain and support the Orbitz Software. AA may make only such copies of the
Escrowed Material as are reasonably required for archival and disaster recovery
purposes, and AA will keep any such copies under lock and key.

     10.5   THIRD PARTY SOFTWARE. If the Orbitz Software includes the Datalex
Software or if Orbitz uses the Datalex Software to provide Hosting and Support
Services, within 60 days following the time that Orbitz decides to use Datalex
Software, Orbitz will use its best efforts to obtain a written agreement with
Datalex, a copy of which will be provided to AA, which provides that (a) in the
event AA receives the Orbitz-owned code as pursuant to this Agreement, the
license to the Datalex Software (including any code developed by Datalex to
support the Website) granted to Orbitz for hosting the Orbitz Software may be
assigned to AA, and (b) AA is a named third-party beneficiary of Orbitz's
agreement with Datalex. In such event, any license fees payable by AA to Datalex
for continued use of the Datalex Software, if any, will not exceed the rates
charged by Datalex to Orbitz to provide the Hosting and Support Services
hereunder. In the event Orbitz does not obtain such a written agreement, then in
the event that AA enters into a direct licensing agreement with Datalex for the
continued use of the Datalex Software, if the license fees payable by AA to
Datalex for such use exceed the rates charged by Datalex to Orbitz to provide
the

                  CONFIDENTIAL                            Page 14
<Page>

Hosting and Support Services hereunder, any amounts due by AA to Orbitz
hereunder shall be reduced by an amount equal to the difference between the
rates charged by Datalex to Orbitz to provide the Hosting and Support Services
hereunder and the licensing fees due from AA to Datalex. Alternatively, in the
event Orbitz does not obtain such a written agreement, Orbitz shall have the
option of removing the Datalex Software provided that such removal does not
reduce the functionality of the then-current Orbitz Software or reduce AA's
ability to host and support the Orbitz Software.

11.  WARRANTIES AND DISCLAIMERS

     11.1   GENERAL WARRANTY. Each party represents and warrants that (a) it has
the full corporate authority to execute this Agreement and perform its
obligations hereunder and (b) execution or performance of this Agreement will
not violate or be considered a breach of any obligation of such party to any
third party. Each party agrees that with respect to any breach of the above
stated warranty, the non-breaching party's sole and exclusive remedy and the
breaching party's sole and exclusive liability will be the indemnity obligations
set forth in Section 12 below.

     11.2   SPECIFIC WARRANTIES.

            (a)     Orbitz represents and warrants that it has, and will
continue to have during the Term, the right to license all Orbitz Software and
sublicense the Datalex Software (if such is used to provide Hosting and Support
Services) in accordance with this Agreement.

            (b)     Orbitz represents and warrants that it will perform the
Services in a good and workmanlike manner and, when applicable, in accordance

its sole and exclusive liability and as AA's sole and exclusive remedy, (i)
correct or re-perform the defective Services or, at Orbitz's discretion, (ii)
refund the fees actually paid to Orbitz for the defective Services. In the event
Orbitz provides the Hosting and Support Services in breach of the above stated
warranty, AA's sole and exclusive remedy and Orbitz's sole and exclusive
liability will be the service level credits or termination as set forth in the
Service Level Agreement.

     11.3   LIMITATION. The warranties and remedies specified in this Section
will not apply to the extent the Deliverables or Services are defective due to
extrinsic causes beyond Orbitz's reasonable control, such as (a) natural
disasters, including without limitation fire, smoke, water, earthquakes or
lightning, (b) electrical power fluctuations or failures, (c) neglect or misuse
by AA, (d) a correction or modification of a Deliverable or Service not
authorized by Orbitz, or (e) the combination of a Deliverable or Service in any
manner not authorized by Orbitz.

            (a)     Orbitz will indemnify, defend and hold harmless AA, as well
as AA's Affiliates and licensees, and each of their officers, shareholders,

from and against any and all Claims, including any related Losses that AA is
required to pay any third party in any way relating to, arising out of or
resulting from: (i) any gross negligence or willful misconduct of any employee
or subcontractor of Orbitz; (ii) breach of any warranty of Orbitz contained in
Section 11.1 of this Agreement; (iii) any actual or alleged infringement of any
patent

                  CONFIDENTIAL                            Page 15

(other than with respect to AA-Competitive Functionality), copyright, trademark,
trade name, trade secret or other proprietary or intellectual property right by
any software or service provided pursuant to this Agreement; or (iv) Orbitz's
failure to comply with any and all applicable laws, rules and regulations.

            (b)     AA will indemnify and hold harmless Orbitz, as well as
Orbitz's subsidiaries, licensees and Affiliates, and each of their officers,
shareholders, directors, employees and agents (collectively, the "Orbitz
Indemnified Parties") from and against any and all Losses in any way relating
to, arising out of or resulting from: (i) any gross negligence or willful
misconduct of any employee or subcontractor of AA; (ii) breach of any warranty
of AA contained in Section 11.1 of this Agreement; (iii) any actual or alleged
infringement of any copyright, trademark, trade name, trade secret or other
proprietary or intellectual property or privacy right by the AA Information; or
(iv) AA's failure to comply with any and all applicable laws, rules and
regulations related to the Website.

     12.2   INDEMNIFICATION PROCEDURES.

            (a)     Promptly after any party entitled to indemnification under
this Section 12 ("Indemnitee") obtains knowledge of the potential existence or
commencement of a Claim, in respect of which Indemnitee is or may be entitled to
indemnification under this Agreement, such Indemnitee will promptly notify the
other party ("Indemnitor") of such Claim in writing; provided, however, that any
failure to give such notice will not waive any rights of Indemnitee except to
the extent that the rights of Indemnitor are actually prejudiced thereby.
Indemnitor will assume the defense and settlement of such Claim with counsel
reasonably satisfactory to Indemnitee at Indemnitor's sole risk and expense;
provided, however, that Indemnitee (i) will be permitted to join in the defense
and settlement of such Claim and to employ counsel at its own expense; (ii) will
reasonably cooperate with Indemnitor in the defense and any settlement of such
Claim; and (iii) will have the right to pay or settle such Claim at any time in
which event Indemnitee will be deemed to have waived any right to
indemnification therefor by Indemnitor. Indemnitor may settle any Claim without
Indemnitee's written consent unless such settlement (A) does not include a
release of all covered claims pending against Indemnitee; (B) contains an
admission of liability or wrongdoing by Indemnitee; or (C) imposes any
obligations upon Indemnitee other than an obligation to stop using any
infringing items.

            (b)     If Indemnitor fails to assume the defense of such Claim or,
having assumed the defense and settlement of such Claim, fails reasonably to
contest such Claim in good faith, Indemnitee, without waiving its right to
indemnification, may assume the defense and settlement of such Claim; provided,
however, that Indemnitor (i) may join in the defense and settlement of such
Claim and employ counsel at its own expense and (ii) will cooperate with
Indemnitee in the defense and settlement of such Claim. Indemnitee may settle
such Claim without Indemnitor's written consent unless such settlement (A) does
not include a release of all covered Claims pending against Indemnitor; (B)
contains an admission of liability or wrongdoing by Indemnitor; or (C) imposes
any obligations upon Indemnitor other than an obligation to stop using any
infringing items. Indemnitor will be liable to Indemnitee for all costs and
expenses incurred in connection with the defense and settlement of any Claim
pursuant to this Section 12.2(b).

            (c)     Upon a determination of liability in respect of this
Section 12, Indemnitor will pay Indemnitee the amount so determined within 10
business days after the date of such determination. If there should be a dispute
as to the amount or manner of determination of any indemnity obligation owed
under this Agreement, Indemnitor will nevertheless pay when due such portion, if
any, of the obligation as will not be subject to dispute. Upon the payment in
full of any claim, either by setoff or otherwise, the party or entity making
payment will be subrogated to the rights of Indemnitee against any person, firm,
corporation or other entity with respect to the subject matter of such claim.

     12.3   INTELLECTUAL PROPERTY REMEDIES. In the event of a Claim under
Section 12.1(a)(iii) above, and in addition to all other obligations of Orbitz
in this Section 12, Orbitz will either (a) provide AA with reasonable assurances
acceptable to AA that AA will continue to have the right to use the affected
products or services or (b) Orbitz will, at its expense, either (i) procure for
AA the right to continue use of such infringing products or services, or any
component thereof; or (ii) replace or modify the same with

                  CONFIDENTIAL                            Page 16
<Page>

non-infringing products or services satisfactory to AA, provided that Orbitz
will provide AA with a comparable temporary replacement product or reimburse AA
for the reasonable costs incurred by AA in obtaining an alternative product in
the event AA cannot use the affected product. If Orbitz cannot accomplish any of
the foregoing within a reasonable time and at commercially reasonable rates,
then Orbitz will accept the return of the infringing component of the products
or services, along with any other components of any products rendered unusable
by AA as a result of the infringing component, and refund the price paid to
Orbitz for such components.

13.  NO CONSEQUENTIAL DAMAGES

     EXCEPT WITH REGARD TO DAMAGES ARISING OUT OF ANY BREACH OF SECTION 8 OR FOR
PERSONAL INJURY, AND THE INDEMNIFICATION OBLIGATIONS CONTAINED IN SECTION 12,
WITH RESPECT TO EACH OF WHICH LIABILITY WILL NOT BE LIMITED PURSUANT TO THIS
SECTION 13, UNDER NO CIRCUMSTANCES WILL EITHER PARTY BE LIABLE FOR ANY
CONSEQUENTIAL, INDIRECT, SPECIAL, PUNITIVE OR INCIDENTAL DAMAGES OR LOST
PROFITS, WHETHER FORESEEABLE OR UNFORESEEABLE, AND WHETHER ARISING OUT OF BREACH
OR FAILURE OF EXPRESS OR IMPLIED WARRANTY, BREACH OF CONTRACT,
MISREPRESENTATION, NEGLIGENCE, STRICT LIABILITY IN TORT OR OTHERWISE. EXCEPT FOR
EITHER PARTY'S INDEMNIFICATION OBLIGATIONS EXPRESSLY SET FORTH HEREIN, CLAIMS
UNDER SECTION 8 HEREOF OR AA'S PAYMENT OBLIGATIONS, IN NO EVENT WILL THE
AGGREGATE LIABILITY WHICH EITHER PARTY MAY INCUR TO THE OTHER PARTY IN ANY
ACTION OR PROCEEDING EXCEED THE GREATER OF (X) THE TOTAL FEES PAYABLE BY AA TO
ORBITZ DURING THE 12 MONTH PERIOD PRECEDING THE EVENT THAT RESULTED IN SUCH
LIABILITY, OR (Y) ONE MILLION DOLLARS.

14.  INSURANCE

     Orbitz will be solely responsible for obtaining and maintaining appropriate
insurance coverage for its activities under this Agreement, including, but not
limited to, comprehensive general liability (bodily injury and property damage)
insurance and professional liability insurance and requiring its subcontractors
to have similar insurance coverage. At AA's request, Orbitz will provide AA with
copies of the certificates of insurance.

15.  DISPUTE RESOLUTION

     Unless otherwise agreed by the parties, any claim, controversy or other
dispute between the parties relating to this Agreement will, before the filing
of any legal action, be submitted to two senior executives representing AA and
Orbitz, respectively. These executives will promptly meet to explore all
possible ways of resolving the dispute amicably. Any resolution upon which these
executives may agree in writing will be final and binding on the parties. If the
executives do not resolve the dispute within 30 days after the initial request
for an executive meeting, the parties may pursue other legal remedies.

16.  TERM AND TERMINATION

     16.1   TERM. This Agreement be in effect as of the Effective Date and will
have an initial term of three years following the Launch Date (the "Initial
Term"). AA may renew this Agreement for up to two (2) successive one-year
renewal terms (each, a "Renewal Term") (the Initial Term and any Renewal Terms
are collectively referred to herein as the "Term"), unless it notifies Orbitz of
its intention not to renew this Agreement at least 60 days prior to the
expiration of the then-current term.

     16.2   TERMINATION FOR CONVENIENCE. AA may terminate this Agreement at any
time upon 60 days notice to Orbitz. If AA terminates this Agreement prior to the
Launch Date, AA will pay Orbitz for services performed and materials delivered
as of the effective termination as well as any pre-approved, out of pocket
expenses incurred by Orbitz, including, without limitation, pre-approved
expenses related to development services, connectivity services, co-location
leases and travel-related expenses. If AA terminates under this provision and
Orbitz is unable to re-deploy staff that had been hired to support Orbitz
obligations under this Agreement, then AA will additionally pay termination fees
equal to two (2) months salary for each such employee. If AA terminates pursuant
to this subsection after the Launch

                  CONFIDENTIAL                            Page 17
<Page>

Date and during the Initial Term, AA will pay Orbitz for services performed and
materials delivered prior to the effective date of termination, plus 50% of the
Fixed Hosting and Support Fees associated with the remainder of the Initial
Term. If AA terminates pursuant to this subsection during any Renewal Term, AA
will only be liable to pay Orbitz for services performed and materials delivered
as of the effective termination date.

     16.3   TERMINATION FOR CAUSE.

            (a)     Subject to the provisions of Section 4.4 hereof, either
party may terminate this Agreement for cause in the event that the other party
fails to cure a material breach of this Agreement within 30 days after receiving
written notice of such breach from the non-breaching party. AA may also
terminate this Agreement for cause in the event that Orbitz is acquired and/or
ownership changes such that an AA Competitor acquires a controlling interest in
Orbitz. For purposes of this provision, "control" means the power to direct or
cause the direction of the management and policies of Orbitz, whether through
the ownership of voting securities, by contract or otherwise. In the event that
AA terminates this Agreement for cause, AA will only be liable to pay Orbitz for
services performed as of the effective termination date.

            (b)     AA may terminate this Agreement in accordance with the
provisions of Section 5 of Exhibit F.

     16.4   EFFECT OF TERMINATION. If this Agreement terminates or expires for
any reason:

            (a)     AA will promptly pay Orbitz any undisputed amounts, provided
that AA may offset any amounts due AA pursuant to Sections 6.3(g)(ii), 16.4(b)
or 16.4(c).

            (b)     In the event of any early termination of this Agreement by
AA prior to the Launch Date, Orbitz will refund to AA, within 60 days following
such termination, any Initial Installment paid by AA pursuant to Section 6.5 of
this Agreement.

            (c)     In the event of any early termination of this Agreement by
AA after the Launch Date pursuant to Section 16.3 of this Agreement, Orbitz will
refund to AA a prorated portion of the Fixed Hosting and Support Fees for the
then-current quarter, according to the number of months remaining in the
then-current contract quarter as of the effective date of such termination.

            (d)     Except as provided in Sections 9.2(b) and 9.2(e) of this
Agreement, all rights AA may have in or to the Orbitz Software, including
without limitation the Core Functionality and the AA-Specific Functionality (but
excluding the AA-Competitive Functionality, which will be owned by AA in
accordance with Section 9.1 of this Agreement), will immediately cease.

            (e)     The provisions of Sections 4.9, 6.6, 6.8, 8, 9.1, 12, 13,
15, 16.4, 17, 18, and 19, and any payment obligations pending as of the date of
expiration or termination, will survive the expiration or termination of this
Agreement for any reason. Further, in the event AA elects to purchase a
perpetual license to the Orbitz Software in accordance with Section 9.2(e), then
the provisions of Sections 9.2(b) through (e), 10.3, and 10.4 will also survive
the expiration or termination of this Agreement for any reason.

17.  NO PUBLICITY

     Neither party will issue a press release, advertisement or public statement
concerning the existence of this Agreement, its contents or the transactions
contemplated by it without the express written consent of the other for each
such event.

                         FIXED HOSTING AND SUPPORT FEES

AA will pay Orbitz a Fixed Hosting and Support Fee in the amount of $[***]for
year one, $[***] for year two, and $[***] for year three. The initial Fixed
Hosting and Support Fee will cover the first year that Orbitz provides
Hosting and Support Services, which will commence on the Launch Date and end
twelve months following the Launch Date. Subsequent years will commence upon
the anniversary of the Launch Date and end twelve months following such
anniversary.

The Fixed Hosting and Support Fees for years four and five, if applicable
pursuant to Section 16.1 of the Agreement, will be determined using a "cost
plus [***]%" model, but in any event will not exceed $[***]. When determining
its cost basis, Orbitz will include only those incremental costs attributable
to hosting AA, and will not include any costs or expenses that would
otherwise be incurred. For example, hardware and head count dedicated to
supporting AA WOULD be included in the cost basis, whereas executive
salaries, Orbitz developer salaries, and advertising expenses WOULD NOT be
included in the cost basis. Orbitz will provide reasonable detail supporting
its cost calculations for years four and five along with assumptions used in
deriving the total amount to be allocated to AA.

The Fixed Hosting and Support Fee for each of the five years will be an
all-inclusive fee for Orbitz to provide the Orbitz Software and the Hosting and
Support Services. AA will not be charged any transaction fees, annual
maintenance and support fees, or fees for Third Party Components, in addition to
the Fixed Hosting and Support Fees during the Term unless otherwise agreed by
the parties. The Fixed Hosting and Support Fee will not include ITA, car, hotel
or other functionality for which Orbitz typically charges a separate fee or the
development of AA-Specific Functionality or AA-Competitive Functionality (which
are separately chargeable as described herein) and will only cover Orbitz
Software functionality for air bookings.

To clarify, the Fixed Hosting and Support Fee includes, but is not limited to,
the following:

          -    Hosting of the Orbitz Software in Orbitz primary facilities
          -    Any required hardware to support hosting and booking engine
               services
          -    Any third party licenses and sublicenses required to meet the
               Launch Date requirements identified as of the effective date of

exceeded by [***]% or more, then the annual Fixed Hosting and Support Fee may
be increased for such year by an amount equal to the increase in costs
incurred by Orbitz due solely to the volumes in excess of the Maximum
Transaction Volumes, plus [***]% of such costs; not to exceed the percentage
by which the Transaction volume exceeds [***]% of the Maximum Transaction
Volume. Orbitz may invoice AA for any increased Fixed Hosting and Support Fee
after the end of such year. For accounting purposes, the parties agree that
[***]% of the Fixed Hosting and Support Fee will be attributable to the
license of the Orbitz Software and the balance will be attributed to services
performed. This allocation shall in no way effect the determination of fees
under Section 9.2(e).

     For example, if the Transaction Volume exceeds the Maximum Transaction
Volume by [***]%, then the annual Fixed Hosting and Support Fee may be
increased for such year by an amount equal to the increase in costs incurred
by Orbitz due solely to the volumes in excess of the Maximum Transaction
Volumes, plus [***]% of such costs; not to exceed [***]%.

                               A. HOSTING SERVICES

1.   GENERAL DEFINITIONS.

     "Expected Transaction Volume" means, for each month during the Term, the
number of Transactions as calculated in accordance with Section A(2) of this
Exhibit.

     "Guaranteed Transaction Volume" means [***]% of the Expected Transaction
Volume.

     "Maximum Transaction Volume" is defined in Exhibit D.

     "Material Service Level Failure" means any of the following: (a) the
Monthly System Availability Commitment (defined below) is not achieved for
any [***] calendar months in any period of [***] consecutive calendar months
during the Service Level Period, or (b) the Monthly System Availability
Commitment is missed by [***]% or more for any calendar month during the
Service Level Period and has been missed by [***]% or more for two or more
previous calendar months during the Service Level Period.

     "Monthly System Availability Commitment" means, for each calendar month,
the number of minutes (expressed as a percentage) during such month that the
Orbitz Software is to be operating to specifications, excluding Excluded Hours
Unavailable (as defined in Section A(4)(d) of this Exhibit). The Monthly System
Availability Commitment will be determined in accordance with Section A(4)(b) of
this Exhibit.

  "Service Level Period" will mean (i) with respect to the first contract year,
  the ten-month period commencing on 60th day after the Launch Date, and (ii)
  with respect to each contract year thereafter, each subsequent twelve-month
  period that Orbitz is obligated to provide the Hosting Services.

  "System Response Time" will mean the total elapsed time added to a Transaction
  from initiating a booking engine service call/request to the receipt of the
  corresponding response attributed to the Orbitz Software.

2.   EXPECTED TRANSACTION VOLUME

     (a)    Sixty (60) days in advance of the Launch Date, AA will provide
Orbitz with a forecast of the Expected Transaction Volumes by month for the
upcoming Service Level Period. The first month's projected volume should be no
more than 1/12th of the Maximum Transaction Volume.

     (b)    If the actual Transaction volume exceeds the Guaranteed Transaction
Volume for any particular calendar month and the Monthly System Availability is
adjusted pursuant to Section A(3)(g) of this Exhibit, the parties may mutually
agree to prospectively adjust the forecast of Expected Transaction Volumes for
the upcoming months, based on historical data and anticipated events. Unless
otherwise agreed by the parties, in no event will the total Expected Transaction
Volumes for a given Service Level Period exceed the applicable Maximum
Transaction Volume.

     (c)    Notwithstanding the foregoing, at least every six months, the
parties will review the Expected Transaction Volume trend and, if indicated, may
mutually agree to prospectively adjust the forecast of Expected Transaction
Volumes for the upcoming months, based on historical data and anticipated
events. Unless otherwise agreed by the parties, in no event will the total
Expected Transaction Volumes for a given Service Level Period exceed the
applicable Maximum Transaction Volume.

3.   MAXIMUM TRANSACTIONS PER HOUR

     (a)    Maximum Transactions Per Hour (MTH) refers to the targeted upper
limit of Transactions per hour based on targeted hardware capacity. For the
purposes of this Agreement, MTH is defined as:

     MTH = [***]

  Where    ETV = Expected Transaction Volume
     MHP = Monthly High Volume Percentage
     MHV = Monthly High Volume Period
     DHP = Daily High Volume Percentage
     DHV = Daily High Volume Period
     HWL = Targeted Hardware Load (as defined in Section A(6) of this Exhibit)

     (b)    For the Launch Date, the following variables will be used:

            Monthly High Volume Percentage (MHP) will be equal to [***]%
            Monthly High Volume Period (MHV) will be equal to [***] days
            Daily High Volume Percentage (DHP) will be equal to [***]% Daily
            High Volume Period (DHV) will be equal to [***] hours Targeted
            Hardware Load (HWL) will be equal to [***]% (as defined in
            Section A(6) of this Exhibit)

(c)  During the first month of the first Service Level Period and every six
months thereafter, the parties will review all defined variables in the MTH
calculation, based on the historical data for the [***] busiest days during
any 30-day period since the last review of the MTH calculation. If a change
in the MHP or DHP variables is favorable to AA (i.e., will result in an
increase in net MTH Transactions), the parties will prospectively change such
variable(s) for the upcoming months, by the full value of such change. If a
change in the MHP or DHP variables is favorable to Orbitz (i.e., will result
in a decrease in net MTH Transactions), the parties will prospectively change
such variable(s) for the upcoming months, by [***]-percent ([***]%) of the
value of the net change. For example, when the historical data is applied, if
the DHP value is actually [***]%, and the former DHP value was [***]%, then
the DHP value will be changed by [***]% of the [***]% change, resulting in a
revised DHP value of [***]%. Should both parties be able demonstrate an
application of the historical data that results in conflicting results, the
MTH calculation will not change for the upcoming period.

4.   SYSTEM AVAILABILITY

 (a) Monthly System Availability shall be defined using the following formula.

          AP =       [***]

  Where   AP = Availability Percentage
     HM = Total hours in a given month
            EHU = Excluded Hours Unavailable (or the fraction thereof)
            HU = Total Hours Unavailable (or the fraction thereof)

 (b) Monthly System Availability Commitment.  Monthly System Availability
 Commitment is defined in the table below for each contract year:

                                 Exhibit F - ii

           3                           [***]%
</Table>

 (c) Hours Unavailable. Hours Unavailable shall be calculated from earlier
 of: (i) the time an Orbitz Trouble Ticket is opened that the Orbitz
 Software is unavailable or (ii) the time Orbitz is notified that the Orbitz
 Software is not operating to specifications, and ends when the Orbitz
 Software is restored to the extent that the system is operating
 substantially in conformance to specifications.

 (d) Excluded Hours Unavailable. Hours unavailable shall not include hours
 or portion thereof in which the Orbitz Software is unavailable due to (i)
 Scheduled Downtime, (ii) hours where actual Transactions exceeded the
 Maximum Transaction Per Hour (MTH) threshold (iii) failure of software,
 hardware, middleware or systems which are necessary for the delivery of the
 Orbitz Software but which are not provided and controlled by Orbitz,
 including, but not limited to, 3rd party networks; SABRE hardware,
 middleware, software, or systems; availability of the World Wide Web;
 software owned or licensed by AA connected to Orbitz Software (excluding
 AA-Competitive Functionality); or Orbitz Software modified by AA.
 Notwithstanding the foregoing, Orbitz will be responsible for maintaining:
 (i) the Orbitz interface between Orbitz Software and AA, (ii) the Orbitz
 interface leading to SABRE, and (iii) communications between the Orbitz
 interface and the SABRE interface.

 (e) Scheduled Downtime. Inaccessibility of the Orbitz Software as part of
 the Website for normal maintenance or upgrades of the Orbitz or its
 Subcontractor's network, equipment and systems ("Scheduled Downtime") will
 occur during Orbitz's or its Subcontractor's regularly scheduled
 maintenance window, which Orbitz or its Subcontractor may, in its or their
 reasonable discretion, adjust to best serve the needs of its network and
 customer base. The parties will coordinate maintenance schedules and Orbitz
 agrees to schedule Scheduled Downtime to coincide with AA's scheduled
 maintenance, unless commercially impractical in which case Orbitz will use
 commercially reasonable efforts to ensure that Scheduled Downtime shall not
 inconvenience AA or its customers. Total Scheduled Downtime will not exceed
 [***] hours in total during a calendar month. Scheduled Downtime that
 violates the foregoing requirements will violate the Monthly System
 Availability Commitment.

 (f) AA will use commercially reasonable efforts to provide Orbitz with at
 least 24 hours advance notification of any AA-initiated promotional events
 that are expected to create a significant increase in the number of booking
 Transactions.

 (g) If the actual Transaction volume less Transactions incurred during
 hours excluded from the System Availability percentage due to the Maximum
 Transactions per Hour (MTH) threshold exceeding the Guaranteed Transaction
 Volume ("Adjusted Actual Transaction Volume") exceeds the Guaranteed
 Transaction Volume for any particular calendar month in the Service Level
 Period for years two and three, the Monthly System Availability Commitment
 will be reduced by [***] percent ([***]%) for each [***] percent ([***]%)
 increment (or portions thereof) that the Adjusted Actual Transaction Volume
 exceeds the Guaranteed Transaction Volume.

 For example, if the Expected Transaction Volume for a given month in the
 second year is [***] Transactions, the Guaranteed Transaction Volume will
 be [***] Transactions. If theactual number of Transactions turns out to
 be [***], and if there were [***] hours where the actual transactions were
 greater than the MTH, and the total number of transactions processed during
 such [***] hours equaled [***] transactions, then the Adjusted Actual
 Transactions would be [***]. The Monthly System Availability Commitment
 will be calculated (in the second year) as [***]% (i.e., [***] divided by
 [***] = [***]%. This results in [***], [***] percent increments (or portions
 thereof) which, in turn, reduces the year two base of [***]% by [***]
 [***] percent ([***]%) amounts, for a total

 reduction of [***] percent ([***]%) to arrive at a Monthly System
 Availability Commitment of [***]%.

     (h)    Service Availability Credits. If Orbitz fails to meet the Monthly
System Availability after the Service Level Period commences, Orbitz will
credit AA a prorated amount of the Fixed License and Hosting Fee ("Hosting
Credit"), calculated as follows: AA will be entitled to receive a credit
equal to [***]percent ([***]%) of the applicable monthly Fixed License and
Hosting Fee for each [***] percent ([***]%) the Service Level falls below the
Monthly System Availability Commitment. The applicable annual Fixed License
and Hosting Fee will be divided by twelve to determine the applicable monthly
Fixed License and Hosting Fee. Such Hosting Credits may be deducted from the
invoice for the next installment of the annual Fixed License and Hosting Fee
or, if there is no subsequent installment due, Orbitz will refund to AA the
amount of such Hosting Credits that have not been applied to invoices,
subject to the limitation set forth in Section C(2) of this Exhibit F.

5.   SYSTEM RESPONSE

     (a)    Orbitz will be responsible for System Response Time; provided,
however, Orbitz will not be responsible for System Response Time in the event
that System Response Time is adversely impacted by factors, occurrences or
circumstances beyond the control of Orbitz. Such factors, occurrences and
circumstances that are deemed to be beyond the control of Orbitz include, but
are not limited to, 3rd party networks, SABRE system response and hours, or
portions thereof, where actual Transactions exceeded the Maximum Transactions
Per Hour (MTH) threshold. Orbitz shall include detailed information as to delays
attributed to Orbitz, Sabre and other causes outside the control of Orbitz in
the monthly System Availability and Performance Report set forth in Section B(4)
of this Exhibit.

     (b)    Orbitz will provide System Response Time within acceptable limits
for at least [***]% of all booking engine service calls/requests. Specific
metric TBD, however, 2 months of response time data should be gathered and
the metric shall be set as a result of looking at [***] standard deviations
from the mean of this data.

     (c)    The "System Response Time Commitment" shall equal an amount
calculated at [***]% higher than [***] standard deviations above the observed
mean.

     (d)    System Response Time Credit. For each month that Orbitz fails to
achieve at least [***]% performance at or below such System Response Time
Commitment, AA shall receive a credit of $[***] subject to the limitation set
forth in Section C(2) of this Exhibit.

     (e)    If the actual Transaction volume exceeds the Guaranteed
Transaction Volume for any particular calendar month, the value of the System
Response Time Commitment will be increased by [***] percent ([***]%) for each
[***] percent ([***]%) increment (or portions thereof) that the actual
Transaction volume exceeds the Guaranteed Transaction Volume.

  6. HARDWARE CAPACITY

  (a) Unless otherwise agreed by both parties, Orbitz will provide performance
   monitoring and capacity planning aimed at keeping sustained hardware loads
   at or below [***]% of capacity based the Expected Transaction Volume.

7.   ESCALATION FOR CASES OF HOSTING FAILURE

     (a)    In the event the Orbitz Software is not accessible or operational
for any consecutive [***]-hour period, or for a cumulative total of [***]
hours or more in any [***]-hour period, AA may, in its sole discretion, send
its employees and/or consultants to the physical facilities at which the
Orbitz Software is hosted to assist with the problem resolution. Orbitz will
cooperate

     (h)    Resolution by Orbitz.

            (i)     Orbitz will use its commercially reasonable efforts to
                    provide a Resolution to each problem, within the specified
                    time periods below in not less than 90% of all reported
                    cases for Severity Levels 1 and 2, and within 80% of all
                    reported cases for Severity Level 3. The AA SPOC will use
                    reasonable efforts to assist the Orbitz SPOC to resolve the
                    problem if problem determination is unclear and impacts the
                    resolution time frames noted.

            (ii)    Orbitz will use commercially reasonable efforts to meet the
                    resolution times (depending on the Severity Level) set forth
                    above with respect to acknowledging, formulating an action
                    plan and resolving such problems by contacting the AA SPOC
                    through e-mail, telephone, fax or other reliable means of
                    communication. Orbitz will maintain a log of all incoming
                    problems for tracking purposes. Orbitz will contact the AA
                    SPOC as soon as Orbitz discovers that a problem cannot be
                    resolved in the specified time period.

            (iii)   In the event that Orbitz reasonably determines that the
                    problem is not an error in or problem with the Orbitz
                    Software, Orbitz will promptly notify the AA SPOC with a
                    detailed explanation. In the event that Orbitz provides such
                    notice, but the AA SPOC continues to request that Orbitz
                    remedy the problem, Orbitz may charge AA for such requests.

2.   NOTIFICATION BY ORBITZ

     (a)    Orbitz will notify AA of (i) any known Orbitz Software or hosted
system errors; (ii) communications failures from Orbitz to the SABRE host;
(iii) availability of the SABRE Gateway, SABRE Host, and SABRE products
called by the Orbitz booking engine within the time frames set forth in
Section B(1)(g) of this Exhibit, depending on the Severity level of such
problem. The parties agree that Orbitz does not have responsibility for
resolving the SABRE specific problems; however, Orbitz has the responsibility
for communicating this information to AA as specified above. For [***] that
Orbitz fails to provide such notification as specified herein for Severity
Level 1 and Severity Level 2 problems within Orbitz's control, AA may receive
a credit of $[***] ("Notification Credit"), subject to the limitation set
forth in Section C(2) of this Exhibit.

     (a)    In the event that a Severity 1 or Severity 2 defect or problem is
not resolved within the response time listed above, such defect or problem
will be reported to the applicable Project Managers. If the Project Managers
cannot agree on a resolution and defect remains unresolved for [***] hours,
the defect will be reported to the Relationship Managers. If the defect
remains unresolved for an additional [***] hours, the Relationship Managers
will call an emergency meeting and AA may receive a credit of $[***]
("Service Resolution Credit"), subject to the limitation set forth in Section
C(2) of this Exhibit.

4.   REPORTING

     (a)    Orbitz will calculate System Availability Credits, System Response
Time Credits, Service Resolution Credits and Notification Credits (whether or
not such calculations result in a Credit due AA) and provide a report of the
results to AA (the "System Availability and Performance Report") within 15 days
after the end of each month.

     I.     C. TERMINATION OPTION AND LIMITATION OF REMEDIES

1.   TERMINATION OPTION

     In the event (a) of a Material Service Level Failure, or (b) that AA is
entitled to receive System Response Time Credits for any [***] months during
a Service Level Period, AA may terminate this Agreement for cause and without
penalty upon thirty (30) days written notice. Such termination will be AA's
sole and exclusive remedy for a Material Service Level Failure or Orbitz's
failure to maintain System Response Time.

2.   LIMITATION OF REMEDIES

     In no event shall the total of System Availability Credits, System
Response Time Credits, Service Resolution Credits and/or Notification Credits
(individually and collectively, a "Credit") due AA during any month exceed
the value of [***] percent ([***]%) of the Fixed License and Hosting Fee for
such month. Further, in no event shall the total of Credits due AA during any
Service Level Period exceed the value of [***] percent ([***]%) of the Fixed
License and Hosting Fee during that Service Level Period. Each such Credit
owed AA will be calculated within 15 days after each month of the Service
Level Period and applied to the next invoice or scheduled payment or, if
there is no subsequent installment due, Orbitz will refund to AA the amount
of such Hosting Credits that have not been applied to invoices.

3.   EARNBACK.

     Orbitz shall have the earnback opportunity with respect to Credits paid or
owed to American pursuant to this Exhibit, as follows:

     Within 30 days after each Service Level Period, Orbitz shall report on each
performance

obligation for which there was a Credit. If Orbitz achieved a yearly performance
average that was greater than or equal to the agreed upon performance
obligation, Orbitz shall be refunded (or relieved from paying, as the case may
be) the amount of Credit formerly paid (or owed) for such performance
obligation.

ORBITZ HIGH AVAILABILITY BOOKING ENGINE

SUMMARY

To provide business continuity in event of a complete or partial data center
disaster Orbitz will run the AA.com booking engine in two data centers
simultaneously in the active-active configuration. Figure 1 provides a high
level overview of the solution.

CAPACITY, PERFORMANCE & CONNECTIVITY

SERVER CAPACITY - Server capacity will be provided in each site to accommodate
the full projected transaction volumes. Component redundancy within each site
will also be maintained to ensure uninterrupted service. These improvements can
be accomplished within the cost structure of the original proposal due to the
reduction in scale of the staging environment. Assets originally dedicated to a
"production-scale" staging environment will be used to provide the incremental
capacity necessary to accommodate running two sites.

SABRE CONNECTIVITY - The additional Sabre connectivity required in the event of
a disaster will be provided via cost effective stand-by T1s.

FRONT END TO BOOKING ENGINE CONNECTIVITY - There will be incremental costs
associated with connecting the AA.com front end application data center to two
booking engine sites. These costs are borne by AA and estimated to be 1.5 times
the cost to connect to a single booking engine site. Although twice as many
circuits will be required between the Exodus data centers, the traffic sent over
any one circuit will be reduced to half the traffic for a single site scenario.

OPERATIONS

SITE OPERATIONS - The data centers will continue to be operated from a single
location at the Orbitz Network Operations Center (NOC) in Chicago. In the event
of a catastrophic event at the NOC location, the service can be monitored and
operated from either of the data center locations.

LOG FILE CONSOLIDATION - Log files between the two booking sites will be
consolidated on an hourly basis for troubleshooting, reporting and accounting
purposes.

FUTURE CONSIDERATIONS

Orbitz currently has facilities in two Exodus data centers in the Chicagoland
area (Oakbrook and Elk Grove Village). AA will be included in Orbitz's future
plans to enhance both geographic diversity of the data centers and vendor
diversity in providers. AA will be migrated along with Orbitz in any future
plans if the costs remain the same for enhancing the geographic and vendor
diversity.
