     industry;

     WHEREAS, among its other businesses, Orbitz provides travel end-users with
     a consumer-oriented Internet travel portal under the "Orbitz.com" domain
     name through which they can complete the booking of air travel, hotel
     accommodations, car rentals, and other travel products (such portal, and
     any related, private labeled or successor Internet sites, such as "Orbitz
     for Business," that are controlled by Orbitz, the "Orbitz Website");

     WHEREAS, Orbitz also provides or may in the future provide to travel
     professionals in the travel industry certain travel-related products and
     services that are not oriented to a consumer end-user and that do not use
     or access the Orbitz Website, including, without limitation, travel agent

     ("Industry Services");

     WHEREAS, in connection with its Orbitz Website business, Orbitz has

     companies to provide the booking engine, fulfillment services, customer
     service center, and other products and services required by Orbitz for the
     Orbitz Website;

     WHEREAS, it is the intent of the parties that this Agreement shall govern
     the provision of such services to Orbitz and the use of the Worldspan
     System, but only in connection with the Orbitz Website business, and not in
     connection with Industry Services or any other business that Orbitz
     operates or may operate."

2.   Section 2.1 is hereby restated in its entirety to provide as follows:

     "2.1   CRS ACCESS. During the Term of this Agreement, Worldspan will
     provide Orbitz, as well as the Booking Engine Provider, the Customer
     Service Center Provider, the Fulfillment Provider, ITA and any other third
     parties that may be engaged by Orbitz to provide products or services for
     the operation of the Orbitz Website and that require such access in order
     to provide those products or services, with access to the Worldspan System
     (including, without limitation, Availability Data Services) for the
     purposes of the operation of the Orbitz Website and in accordance with the
     provisions of this Agreement. Orbitz is authorized to access Availability
     Data Services, for the purposes of processing any Supplier Link Segments as
     set forth in Sections 2.10 and 4.7 herein and as otherwise in a manner that
     is consistent with this Agreement."

3.   A new Section 2.10 is hereby added to the Agreement to provide as follows:

     the purpose of providing such Worldspan Customer access to the Orbitz
     Website, unless Orbitz has obtained Worldspan's prior written consent. For
     the avoidance of doubt, the license in the previous sentence does not
     authorize the use or remarketing of Availability Data Services other than
     for the Orbitz Website.

     (b)    Orbitz may terminate use of the Availability Data Services upon
     [***] prior written notice to Worldspan. Worldspan may terminate provision

     "USE OF WORLDSPAN SYSTEM. Orbitz has incorporated the Worldspan System into
     the Orbitz Website and will use reasonable business efforts to encourage
     Users to book travel by means of the Orbitz Website so as to generate Net

     the foregoing sentence shall not impair or restrict Orbitz' right to

     provision of such notice to Worldspan, for the remainder of the calendar
     quarter and until the end of the calendar year (or such earlier time as
     Orbitz declares, by written notice to Worldspan, the conclusion of the Safe
     Harbor Event), Orbitz has eliminated all Airline Direct Connect Segments
     and all Direct Connect Car Segments and processes 100% of Orbitz' air and
     car bookings through Worldspan.

     (c)    Orbitz agrees [***]. Orbitz will use reasonable business efforts to
     prevent unauthorized or improper use of or access to the Worldspan System
     and to ensure that its employees, agents, third parties that may be engaged
     by Orbitz to provide products or services for the operation of the Orbitz
     Website, and Users access and use the Worldspan System in compliance with
     all reasonable instructions provided by Worldspan, including the following:

     (i)    The Worldspan System may not be used to transmit personal messages,
            make speculative or improper bookings, train anyone other than
            Orbitz employees, agents, or Users, or publish or disseminate a
            compilation of air carrier service or other information.

            Proper and permitted use of the Worldspan System, including data and
            services provided through such system, consists of (i) using the
            Availability Data Services with respect to one or more Airline
            Direct Connect Customers for purposes of and consistent with this
            Agreement, (ii) making proper and legitimate reservations and
            booking Segments, (iii) issuing travel documents related to such
            Segments, and (iv) performing normal accounting and record keeping
            functions, all of the foregoing only in accordance with rules and
            regulations issued from time to time by Worldspan and subject to the
            terms and conditions of this Agreement. Improper use of the
            Worldspan System includes, without limitation, making speculative or
            improper bookings, reserving space in anticipation of demand, and
            improper creation or modification of records.

            Orbitz shall not use or access the Worldspan System, including data
            and services provided through such system, without Worldspan's prior
            written consent (i) to make bookings on any CRS other than
            Worldspan, (ii) to make bookings on any airline or other reservation
            system (except as permitted in Section 2.10), (iii) to develop or
            test software applications, including without limitation, booking
            engines, corporate booking programs, FLIFO-type products, fares and
            pricing tools, caching products, travel agent desktop tools, and
            airline hosting applications (which such prior written consent shall
            not be unreasonably withheld), or (iv) in any other manner that is
            not expressly permitted hereunder or is unauthorized or improper.

            Orbitz' employees, agents, and Users may not enter passive bookings
            (e.g., GC, HK, MK or BK codes) into the Worldspan System when no
            corresponding space has been reserved with the corresponding travel
            supplier's internal reservations system. Any passive bookings will
            be removed from the Worldspan System if the corresponding space is
            cancelled.

     (v)    The material and information supplied by Worldspan will not be
            manipulated in a manner that would lead to inaccurate, misleading,
            or discriminatory presentation of information to consumers.

            Orbitz will promptly report to Worldspan any incidents of suspected
            unauthorized access to or use of the Worldspan System and will use
            reasonable commercial efforts to curtail access to or use of the
            Worldspan System by any User upon Worldspan's reasonable request.

            Other than as described in Section 2.10, Section 4.7(c), oras may be

            effective [***], use the Worldspan System to service Supplier Link

            storage, queues, profiles, fares and pricing systems, Auto Re-Issues
            or Rapid Re-Price. Also, Orbitz shall not use the Worldspan System
            to search for fares, rates, schedules or itineraries that involve
            Airline Direct Connect Segments."

     Term of this Agreement, in the event Orbitz does not satisfy the minimum
     Net Segments or minimum Net Car Segments requirements described in
     subsection (a) or (b) below, Orbitz will pay Worldspan a fee ("Minimum
     Segment Fee") calculated as follows:

     (a)    In the event Orbitz does not satisfy the requirements of Section
     3.2(b) with respect to a particular calendar quarter, then, in addition
     to all payments under this Agreement, Orbitz shall pay to Worldspan a
     Minimum Segment Fee equal to the difference between the Applicable
     Quarterly Minimum for such calendar quarter and the Adjusted Quarterly
     Net Segments applicable to such calendar quarter, multiplied by $1.78.

     (b)    In the event Orbitz books a [***] Segment in a particular calendar
     quarter through a [***] and does not, during such calendar quarter, book at

     to the difference between the Applicable Quarterly [***] Segments set forth
     below and the Adjusted Quarterly [***] Segments (as defined below) for such
     calendar quarter, [***].

     For purposes of the foregoing calculation, the number of Net [***] Segments
     (if any) by which the Applicable Quarterly [***] Segments for a particular

     Segments in a particular calendar quarter plus the number of excess Net
     [***]Segments carried forward, if any, from the previous calendar
     quarter(s) in such calendar year shall be referred to as the "Adjusted

     and books of account relating to Net Segments and Supplier Link Segments
     generated by Orbitz, the operation of the Orbitz Website, and other

     supplied. Information disclosed to Worldspan or to its auditing
     representative in the course of such inspection shall be subject to the
     confidentiality requirements of this Agreement and may not be used for any
     purpose whatsoever other than the determination of compliance with Orbitz's

     "9.17  NO CONFLICT. (a) Worldspan represents and warrants to Orbitz that

     Worldspan of its obligations hereunder does or will constitute a breach,
     default, or violation of any of Worldspan's obligations under any contract,
     agreement, license, consent or permit to which it is a party.

     (b)    Except as provided in the next sentence, Orbitz represents and
     warrants to Worldspan that neither the execution and delivery of this
     Agreement nor the performance by Orbitz of its obligations hereunder does
     or will constitute a breach, default, or violation of any of Orbitz's

subscribe to the Supplier Link booking service.

"Worldspan remains committed to the efficiency of the industry," said Paul
Blackney, Worldspan's president and chief executive officer. "Our partnership
with Orbitz is a strong commitment by both companies to do what it takes to
provide valuable innovations to the traveling public. We pride ourselves on our
inventive technology, innovative solutions and customer support and look forward
to continuing to be Orbitz' technology partner."

"Worldspan's reliability and innovation has been a contributing factor to
Orbitz's success," said Jeff Katz, Orbitz President and CEO. "We look forward to
continuing our successful technology partnership as Orbitz grows its business as
