     2. LICENSE GRANT

(a) LICENSE GRANT. Licensor hereby grants to Licensee and its Affiliates a
worldwide, non-exclusive, irrevocable (except as expressly provided herein)
license during the term of this Agreement to use, perform

                                                                               2
<Page>

and display the Licensed Software and Documentation in accordance with the terms
of this Agreement. Licensee may use the Licensed Software to generate, sort,
price and select airline itineraries and determine availability of selected
flights, classes of service and booking codes, in order to provide travel
planning and related services to End Users. In addition, End Users shall be
permitted to access and use the Licensed Software at the Site(s) or a co-
branded section of the Site(s). The foregoing license grant shall also include
the right to permit third party vendors, outsourcers and other service providers
to render services to the Licensee and its Affiliates relating to the design,
development and maintenance of the Licensed Software, subject to all the other
restrictions and conditions contained in this License Agreement.

     (b) RIGHTS AND RESTRICTIONS.

          (i)    Except as provided in Section 19(f), Licensee shall not have
the right to sublicense or transfer the Licensed Software.

          (ii)   Licensee shall not have the right to use the Licensed Software
to provide services to an airline or to an affiliate of an airline which is
engaged in the business of selling travel on such airline.

          (iii)  Licensee may make copies of the Licensed Software for staging,
back- up, disaster recovery, testing or archival purposes, and as necessary to
utilize the Licensed Software in its business, subject to the other terms and
conditions of this Agreement.

          (iv)   Licensee shall be permitted to use (including via a network)
the Licensed Software on a worldwide basis and on an unlimited number of
machines without restriction as to the number of users, but only subject to the
restrictions and limitations contained herein.

          (v)    Licensee agrees that it shall not reverse engineer,
disassemble, decompile, modify, profile or monitor the Licensed Software for any
purpose whatsoever, nor will Licensee implement or permit procedures such as
"port scans", "tiger attacks" or other techniques designed to gain access to the
Licensed Software (or to computers running the Licensed Software) which have not
been specifically authorized by Licensor; provided, however, that Licensee may
monitor the operation of the programs with Licensor's prior consent, which will
not be unreasonably withheld, provided that such monitoring is in accordance
with all the other provisions of this Agreement. The foregoing provision shall
not be deemed to prohibit Licensee from monitoring the inputs to or outputs from
the Licensor's Application Program Interfaces (APIs). Without limiting the
foregoing, Licensee specifically agrees that it will not observe, read, copy,
profile or monitor the contents of any Packets (or write or use any software
program which permits or enables any of such activities) for any purpose
whatsoever; provided, however, that Licensee may monitor external
characteristics of Packets such as volume of Packets moving across the network
or the size of Packets. In addition, Licensee shall have the right to monitor,
through the use of passive monitoring agents that at no time during their
operations would result in changing configurations, changing the intended
operation of the system, or degrading performance, the performance (i.e, uptime,
disk space usage, bandwidth performance, memory utilization, etc.) of the
hardware and equipment on which the Licensed Software is running at the Atlanta
Facility and the Chicago Facility (as defined in the SLA).

          (vi)   The Licensor has designed the Licensed Software so that it
scales to accommodate arbitrary numbers of queries. However, the Licensee may
wish to scale its system using a system architecture different than that
presently used by the Licensed Software. In such event, Licensor will have the
opportunity, on its own or jointly with the Licensee, to modify the Licensed
Software, pursuant to an SOW, to

                                                                               3
<Page>

accommodate such engineering requirements as may be occasioned by Licensee's
desire to scale its system according to a different architecture. In the event
that Licensor is unwilling or unable to provide appropriate modifications to the
Licensed Software, Licensor will make available to Licensee such information as
may be reasonably required for Licensee to make such modifications.

          (vii)  Except as expressly set forth in this Agreement, Licensee shall
not have any right to make, prepare or reproduce derivative works of the
Licensed Software.

          (viii) Notwithstanding any other provision of this Agreement, Licensee
shall be prohibited from providing the Licensed Software to a CRS, pursuant to
the restrictions more specifically set forth in Exhibit B. It is the parties'
intention that it not be considered a violation of such Exhibit B if such
restrictions are violated inadvertently by Licensee as a result of a CRS
Entity's (as defined therein) having access to the Licensed Software at the Site
without Licensee's acquiescence or control.

     3. DOCUMENTATION

When delivering the Licensed Software (including any Upgrade Releases) to
Licensee, Licensor shall supply applicable Documentation in printed and/or
electronic formats, as requested by Licensee. Such Documentation shall be
provided at no additional charge. If Documentation is developed specifically for
or at the request of Licensee, then the preparation of such Documentation shall
be undertaken pursuant to an SOW. Licensee shall have the right, as part of the
license granted herein, to make as many additional copies of the Documentation
for its own internal use as it may reasonably determine are necessary.

     4. SERVICES

     (a) STATEMENTS OF WORK. Licensor shall furnish to Licensee such services as
Licensee may request from time to time, including services relating to
integration and customization of the Licensed Software, at Licensor's
then-current rates; provided that Licensor shall not be required to commit more
than two (2) full-time equivalents (calculated on a monthly basis) to perform
such services (including any services rendered pursuant to paragraph (d) below)
at anyone time. The provision of such services shall be governed by statements
of work executed by the parties, a form of which is attached hereto as Exhibit C
("SOWs"). In addition, Licensor agrees to maintain the performance of the
Licensed Software such that it is reasonably comparable, in terms of search time
and number of pricing solutions (combinations of itineraries and fares)
searched, with similar products available from any Competitive Entity.
"Competitive Entity" means the following entities that provide online travel
services: Sabre Inc. (including Easy Sabre, GetThere Inc., and Travelocity),
Expedia Inc., Priceline.com Incorporated, Cendant Corporation (including

reporting will be included in SOWs. Unless otherwise agreed in the SOW, Licensor
shall present to Licensee or Licensee's designated project manager or project
management company a progress report on a monthly basis in Licensor's standard
FORM and containing, with respect to each active project, information relating
to Licensor's progress toward completion of that project, and deliverables for

shall be treated as, the disclosing party's Confidential Information pursuant to
Section 15 of this Agreement. In addition, any information obtained by either
party as a result of its access to, and use of, the other party's computer and
electronic storage systems shall be deemed to be, and shall be treated as, the
other party's Confidential Information pursuant to Section 15 of this Agreement.

     (d) COOPERATION. Licensor agrees to reasonably cooperate with Licensee and
any third parties that Licensee may engage in connection with the development,
testing, integration, maintenance and operation of the Site and related systems.
Resources expended by Licensor in providing such cooperation will be included in
the two full-time equivalents limitation described in paragraph (a).

     (e) SOFTWARE MAINTENANCE. Licensor shall provide the maintenance and
technical support services set forth in the SLA in accordance with the service
levels also set forth therein.

     5. PERSONNEL

     (a) LICENSOR PERSONNEL. It is understood and agreed that Licensor's

employees, including without limitation, vacation, holidays, sick leave,
worker's compensation and unemployment insurance. Further, Licensee shall not be
responsible for withholding or paying any taxes or social security on behalf of
Licensor's employees. Licensor shall be fully responsible for any such
withholding or paying of taxes or social security. Notwithstanding the
foregoing, Licensee may at any time require Licensor to remove from any
Licensee-related activity any personnel which Licensee, in its reasonable
discretion, deems to be unsatisfactory (by way of example but not limitation,
unprofessional or inappropriate conduct). Any such request for removal shall be
sent in writing to Licensor.

     (b) STAFFING. Licensor shall staff each such project with personnel with
sufficient skill, experience and ability to complete the project on the schedule
specified in the applicable SOW.

     6. OWNERSHIP

     (a) LICENSED SOFTWARE. Licensee acknowledges that Licensor is the sole and
exclusive owner of all rights in and to the Licensed Software and that other
than the license granted hereby, no proprietary rights, including but not
limited to copyrights and patents, in the Licensed Software are being
transferred to Licensee.

     (b) LICENSEE INTERFACES. Licensee shall have the right to interface to the
Licensed Software and to use it in conjunction with other software, programs,
routines and subroutines developed or acquired by Licensee, except that, other
than as set forth in Section 2(b)(v), (i) Licensee shall use the Licensed
Software as a whole and shall not have the right to substitute other software
for portions of the Licensed Software and (ii) any interfaces between those
portions of the Licensed Software comprising the low-fare search servers and
availability servers, on the one hand, and other such software, programs, etc.
of the Licensee, on the other hand, will occur via the Licensor's documented XML
Application Program Interface (API) or another API provided by or approved in
advance by Licensor. Licensor shall have no ownership interest in any other

<Page>

virtue of its having been interfaced with or used in conjunction with any
Licensed Software. In addition, Licensee may request that Licensor enter into an
SOW to modify the Licensed Software for Licensee (but not for Licensor's other
licensees) in the event Licensee is able to obtain availability information from
airlines which airlines do not make generally available. In the event such
modification would not degrade the performance of availability caching for
Licensor's other licensees, Licensor may enter into such an SOW and the
provisions of this Agreement will not be deemed to prohibit Licensee's use of
the Licensed Software as so modified.

     (c) ORBITZ-DEVELOPED SOURCE CODE. Licensor acknowledges that Licensee shall
be the exclusive owner of all right, title and interest, including all
intellectual property rights, in and to any and all source code developed solely
by or for Licensee related to or in support of any object code of the Licensed
Software, including, but not limited to, source code that improves the
scalability of the Licensed Software. The foregoing will not be deemed to alter
the rights of the respective parties under applicable law and shall not preclude
either party from filing patents regarding inventions or discoveries invented or
discovered by such party.

maintain and update pre-existing data and information about End Users for use
with (or resulting from use of) the Licensed Software, and (ii) generate,
manage, modify, maintain and update additional such data and Information (such
pre-existing data and information and such additional data and information are
referred to collectively as "Licensee Data"; provided that schedule, fare and
availability data used by the Licensed Software shall not constitute Licensee
Data). Licensee Data shall be treated as Licensee Confidential Information, and
Licensee shall retain all right, title and interest in and to all Licensee Data.
Notwithstanding the foregoing, Licensee agrees that Licensor will have access to
Licensee Data comprising aggregated statistics relating to both the usage of the

<Page>

                       Licensor an additional license fee of [***] per PNR in
                       excess of such Permissible PNRs, regardless of whether
                       such PNRs are created with respect to the Orbitz URL or
                       any Site.
             (iv)      Within forty-five (45) days after the end of each fiscal
                       quarter during each License Year, Licensee will certify
                       to Licensor the number of PNRs created during such
                       quarter and the cumulative number of PNRs created during
                       the then-current License Year.

     (d) INCREMENTAL FEES. At the end of each License Year, Orbitz shall

applicable SOW, in addition to the hourly rates described in the applicable SOW,
Licensee shall pay Licensor's actual out-of-pocket expenses of the types agreed
to in writing by the parties, provided that (1) Licensor obtains Licensee's
prior written approval before incurring such reimbursable expenses; or (2) such
expenses are incurred in accordance with Licensee's then-current standard policy
regarding such reimbursable expenses (advance notice of any modifications to
which Licensee agrees to provide to Licensor). Licensor agrees to provide
Licensee with access to such original receipts, ledgers, and other records as
may be reasonably appropriate for Licensee or its accountants to verify the
amount and nature of any such expenses. The timing of Licensee ' s payment
obligations under this paragraph (e) will be subject (in the case of costs and

     (i) INVOICING. Unless otherwise provided in this Section 8, Licensor shall
invoice Licensee on a monthly basis for all fees and charges accruing hereunder
or pursuant to an SOW, and Licensee shall pay all such invoiced amounts within
thirty (30) days after receipt of a proper and correct invoice; provided, that
Licensor shall not be obligated to invoice any amounts (such as the Basic
License Fee) the amount and timing of which are fixed by this Agreement and/or
by Exhibit G. Such invoices shall provide such detail as required by the
invoicing policy set forth at Exhibit F, and shall be accompanied by any
supporting documentation required by such policy. Upon mutual agreement of the
parties, such invoicing policy may be changed from time to time. In the event of
a good faith dispute as to any portion of an invoice, Licensee shall give
written notice to Licensor, within fourteen (14) days after receiving such
invoice, stating the details of any such dispute and shall promptly pay any
undisputed amount in accordance with this Agreement. Within thirty (30) days
after the termination or expiration of this Agreement for any reason, Licensor
shall submit to Licensee an itemized invoice for any fees or expenses
theretofore accrued under this Agreement. Licensee, upon payment of accrued
amounts so invoiced, shall have no future liability or obligation to Licensor
whatsoever for any further fees, expenses, or other payments.

     (i) TAXES. Licensee shall be responsible for the payment of any federal,
state or local taxes (other than taxes based on licensor's income) assessed on
the Licensed Software or services provided under this Agreement.

     9. MOST FAVORED CUSTOMER

Licensor agrees to treat Licensee as its most favored customer, and Licensor
represents that all of the prices, warranties, benefits and other terms being
provided hereunder, considered as a whole, are equivalent to or better than the
terms being offered by Licensor to its current customers for substantially
similar software. In its sole right and discretion, Licensor may establish the
pricing for any application it develops for any other licensee. However, in the
event Licensor licenses to a third party software which is substantially similar
to the Licensed Software, at an effective price which is lower than that
provided hereunder or on more favorable terms (provided that such price and
terms shall be considered as a whole), Licensor shall prospectively (but not
retroactively) reduce the price to be charged to Licensee and/or revise the
terms such that, considered as a whole, they are at least as favorable as that
granted to such third party. In determining whether software is "substantially
similar" or whether the terms charged to a third party are "more favorable,"
Licensor will take into account the number of transactions for which a licensee
is using the software, the duration of the license, the amount of integration
work required, the minimum license fee, the expected volume of transactions, and
whether or not there is a per-transaction component to the pricing. Without
limiting the foregoing, the parties specifically agree that a license by the
Licensor to an airline will not trigger the provisions of this Section 9.

     10. TERM AND TERMINATION

     (a) TERM OF AGREEMENT. The term of this Agreement and the license granted
to Licensee hereunder shall be deemed to have commenced as of July 1, 2000 and
shall terminate on September 30, 2007. Notwithstanding the foregoing, Licensor
agrees that any use by Licensee of the Licensed Software prior to the
commencement of this Agreement was authorized by Licensor, and Licensor hereby
waives any claim for unauthorized use and for license fees or other compensation
for such use prior to July 1, 2000.

     (b) TERM OF SOWS. Unless specified otherwise in an SOW or earlier
terminated in accordance with this Agreement, each SOW shall remain in full

                                                                               9

11(b)(iii), 11(b)(vii), 12(a), 14 or 15, so as to cause material damage to
Licensee, and such breach is not cured within thirty (30) days after receipt of

the benefit of creditors, if such petition or proceeding is not dismissed within
sixty (60) days of filing. In the event of termination by Licensee pursuant to
this Section 10(c), Licensor shall refund to Licensee a pro rata portion of the
license fees paid by Licensee (other than the $[***] license fee paid by
Licensee in accordance with Section 8(a)) proportional to the license term
remaining in the License Year as of the date of termination and maintenance and
support fees set forth herein or in the SLA which were paid in advance and have
not been earned as of the effective date of termination.

     (d) TERMINATION FOR CAUSE BY LICENSOR. This Agreement and the license
granted hereunder (or an SOW) may be terminated by Licensor for cause
immediately by written notice in the event Licensee breaches one of the

the restrictions regarding use of electronic resources set forth in Section
4(c); (iii) Licensee's warranty set forth in Section 11(a); (iv) the

following provisions, and such breach is not cured within thirty (30) days after
receipt of written notice thereof from Licensor: (i) Licensee' s payment

relating to source code restrictions and confidentiality set forth in Section
14(c) and (d).

     (e) TERMINATION OF SOWS. Either party may terminate an SOW in the event the
other party materially breaches any provision thereof and fails to cure such
breach within thirty (30) days after receipt of written notice thereof from the
non-breaching party.

     (f) DUTIES ON TERMINATION. Upon expiration of this Agreement at the end of
the term or termination by Licensee in accordance with Section 10(c), Licensor
shall provide to Licensee, upon Licensee's request, at Licensor's then-standard
rates and upon Licensee's continued payment of a pro-rated license fee pursuant
to Section 8(b), reasonable termination assistance, including the right to
continue to use the Licensed Software as set forth herein, in connection with
the transition from the Licensed Software to another system. Licensor shall
provide the foregoing rights and services for up to three (3) months in the
event of expiration of this Agreement and up to six (6) months in the event of
termination by Licensee in accordance with Section 10(c). Such termination
assistance shall include, without limitation, cooperating

frequently than quarterly) all source code for each update, bug fix, upgrade,
release or version of the Licensed Software, and at least once each calendar
year, Licensor shall deliver to the escrow agent a fully updated copy of all
source code for the Licensed Software. Such additional source code deposits

with the quarter ending June 30, 2001, Licensor shall certify to Licensee that
all required source code deposits were made. In the event Licensor fails to
provide such certification, Licensee shall send Licensor notice of such failure.

proceeding relating to insolvency, receivership, liquidation or composition for
the benefit of creditors; (iii) Licensor becomes the subject of an involuntary
petition in bankruptcy or any involuntary proceeding relating to insolvency,

this Agreement or under the SLA (including Maintenance Services as defined in
the SLA) and fails to cure such breach within (A) fifteen (15) days from the
date of receipt by Licensor of written notice from Licensee describing in
reasonable detail the grounds for Licensee's belief that such material breach
occurred, in the event the breach causes a Severity Level 1 or Severity Level 2
problem (as defined in the SLA), or (B) sixty (60) days from the date of receipt
of such notice in the event the breach causes Severity Level 3 or Severity Level
4 problems (as defined in the SLA) and such problems are chronic and continuous
(provided, however, that in both cases, prior to obtaining the release of the
Deposited Materials pursuant to this clause (iv), the parties shall have
completed the expedited dispute resolution procedures provided for under Section
18(b); (v) Licensor notifies Licensee of its intent to cease to offer
maintenance and support services for the Licensed Software; or (vi) Licensor
fails to provide certification of a quarterly source code deposit to Licensee
within thirty (30) days after receipt of notice from Licensee regarding such
failure, as set forth above in Section 14(a). In the event Licensee has the
right to have the Deposited Materials released to it pursuant to the procedures
set forth in Section 14(b)(iv) above, then Licensee shall have the option to (1)
have such Deposited Materials released to it immediately, in which case Licensee
shall have no further right to terminate this Agreement under Section
10(c)(iii); or (2) have the Licensee's chief technology officer inspect all
source code for the Licensed Software at Licensor's offices for a period not to
exceed five (5) days, and after such inspection, Licensee may choose to
terminate this Agreement in accordance with Section 10(c)(iii) or receive the
Deposited Materials from escrow, in which case Licensee shall have no further
right to terminate this Agreement under Section 10(c)(iii).

     (c) RESTRICTIONS. In the event the Deposited Materials are released to

requirements or industry standards; (iii) to add new features, functionalities,
or performances to the Licensed Software; and (iv) to perform the maintenance
and support services that Licensor was to perform under this Agreement and the
SLA, including without limitation the development of Upgrade Releases; provided,
however, that any modification by Licensee of the Licensed Software shall excuse
Licensor from any further performance of its maintenance and support obligations
with respect to such portions of the Licensed Software that were modified by
Licensee. Unless otherwise provided in this Agreement, the scope of and
restrictions on the licenses granted hereunder, and the intellectual property
rights of the parties, shall continue to be as set forth in Section 2 and 6,
provided that Licensee shall own all source code and object code developed by or
for Licensee after the release of the Deposited Materials to Licensee. The
foregoing restrictions are in addition to any restrictions imposed on
Confidential Information pursuant to Section 15.

     (d) CONFIDENTIALITY. The escrow agreement (or a separate agreement entered
into between Licensor and Licensee) shall also include reasonable provisions for
maintenance by Licensee of the confidentiality of the Deposited Materials in the
event the Deposited Materials are released to Licensee, including but not
limited to requirements that (i) access to the source code and documentation
related to such source code ("Access") be limited only to those employees or
third party contractors or outsourcers of Licensee engaged in operating,
maintaining, supporting and updating the Software; (ii) Licensee shall maintain
a list of all such individuals to whom Licensee has granted Access and shall
provide a copy of such list to Licensor upon Licensor's request; (iii) all such
individuals shall, as a condition of and prior to being granted such Access,

                                                                              14

execute a non- disclosure agreement containing provisions at least as
restrictive as those set forth in Section 15, and Licensee shall maintain such
agreements available for inspection and copying by Licensor upon reasonable
request; and (iv) the Deposited Materials shall be stored in a secure manner.

     15. CONFIDENTIAL INFORMATION

     (a) CONFIDENTIAL INFORMATION. Each party has disclosed (prior to the
commencement of this Agreement) and may disclose Confidential Information to the
other party which it intends the other party to maintain in confidence, and each
party agrees to comply with the provisions of this Section 15 with respect to
all such Confidential Information. As used herein, each party which discloses
such information is referred to as a "Disclosing Party" and each party which
receives such information is referred to as a "Receiving Party." "Confidential
Information" means Disclosing Party's confidential and proprietary inventions,
products, designs and ideas, including computer software, functionality,
concepts, processes, internal structure, external elements, user interfaces,
technology and documentation, as well as confidential and proprietary
information relating to Disclosing Party's operations, plans, opportunities,
finances, research, technology, developments, know-how, personnel, and any third
party confidential information disclosed to Receiving Party. Without limiting
the foregoing definition, the Licensed Software, the Documentation (except
Documentation reasonably expected to be provided to End Users regarding the use
of the Licensed Software) and all Packets are "Confidential Information" of the
Licensor. The terms and conditions of this Agreement are also "Confidential
Information." However, "Confidential Information" shall not include information
(a) already lawfully known to Receiving Party if the Receiving Party does not
then have a duty to maintain its confidentiality, (b) developed independently by
the Receiving Party, (c) generally known to the public through no fault of the
Receiving Party; (d) lawfully obtained from a third party not obligated to
preserve its confidentiality; (e) required to be disclosed by law, regulation or
order of a court of competent jurisdiction or other governmental authority
(except that prior to any such disclosure the Receiving Party shall give the
Disclosing Party notice thereof and afford the Disclosing Party the opportunity
to oppose any such disclosure).

     (b) NON-DISCLOSURE. Receiving Party acknowledges that Confidential
Information is confidential, proprietary and/or trade secret information of the
Disclosing Party. Receiving Party shall not use the Confidential Information for
any purpose other than in accordance with this Agreement, and shall not disclose
Confidential Information to anyone other than its employees and contractors who
legitimately need access to it and who have signed confidentiality agreements
comparable in scope to this Section 15. Receiving Party shall notify each of its
employees and contractors who are given access to Confidential Information that
they have an obligation not to disclose Confidential Information and shall take
such steps as are reasonably necessary to insure compliance with this
obligation. Receiving Party shall safeguard Confidential Information with
reasonable security means at least equivalent to measures that it uses to
safeguard its own proprietary information. Receiving Party shall store
Confidential Information in a safe and secure location. Receiving Party may not
remove copyright, trademark, trade secret, confidentiality, and patent notices
from Confidential Information.

     (c) NO WARRANTIES. Except as set forth in Section 11, all Confidential
Information is provided  "as is," without any express or implied warranty of any
kind.

     (d) BREACH OF CONFIDENTIALITY OBLIGATIONS. Receiving Party hereby
acknowledges that unauthorized disclosure or use of Confidential Information
shall cause immediate and irreparable harm to Disclosing Party for which it
would not have an adequate remedy at law. Accordingly, Disclosing Party shall
have the right to

                                                                              15
<Page>

seek and obtain preliminary and final injunctive relief to enforce this
Agreement in case of any actual or threatened breach, in addition to other
rights and remedies that may be available to Disclosing Party.

     16. RELATIONSHIP OF THE PARTIES

The parties shall be treated for all purposes as independent contractors, and no
provision of this Agreement shall be construed to constitute or create a
partnership, joint venture, agency or formal business organization of any kind.

     17. PUBLICITY

     (a) At no time shall either party release a press release that mentions the
other party unless the other party has consented in writing in advance to such
press release; provided, however, that each party may approve in writing in
advance a representative sample of a reference to such party, which may then be
used by the other party in press releases without further approval from such
party.

     (b) For so long as the Licensed Software is used on the Site(s), the
Site(s) will contain the Licensor's logo with words to the effect of "powered by
ITA Software", or such similar language the content and placement of which will
be mutually determined by the parties.

     18. DISPUTE RESOLUTION

     (a) DISPUTE RESOLUTION. The parties shall first attempt in good faith to
resolve any dispute arising out of or relating to this Agreement by negotiation,
then arbitration, in accordance with the dispute resolution procedures as set
forth in Exhibit E.

     (b) EXPEDITED PROCESS. In the case of a dispute as to whether the Licensee
is entitled to release of Deposited Materials from escrow as a result of
Licensor's material failure to maintain or support the Licensed Software, as
described in Section 14(b)(iv), the procedures set forth in Exhibit E will be
modified as follows: (i) in the event Licensee believes Licensor has materially
failed to maintain or support the Licensed Software, as described in Section
14(b)(iv), then Licensee may initiate the negotiation procedures set forth in
Section 1 of Exhibit E at any time after Licensee has given Licensor the notice
described in Section 14(b)(iv); (ii) in the event such negotiation procedures
are unsuccessful in resolving such dispute, either party may initiate
accelerated arbitration proceedings by notifying the other party at any time
following the end of the 15-day or 60-day period, as applicable, described in
Section 14(b)(iv); (iii) immediately upon the giving of such notice, the parties
will exercise their best efforts to select a mutually acceptable, technically
competent arbitrator through the Information Technology Association of America,
and such selection shall occur within seven (7) days of the giving of such
notice; (iv) as soon as the parties select an arbitrator, the parties and the
arbitrator shall immediately determine a mutually acceptable date(s) for such
arbitration to occur, which shall be not less than fourteen (14) nor more than
thirty (30) days after the date the arbitrator is selected, and in determining
such date, the parties agree to make the appropriate resources available for
arbitration on a "highest priority" basis; (v) at such arbitration each party
will have a maximum of two hours to present its case, for a total of not more
than four hours, and the arbitrator will have an additional four hours within
which to question the parties and allow the parties to rebut each other's
arguments; (vi) the arbitrator will be instructed to exercise his or her best
efforts to present his decision within fourteen (14) days of the last date on
which arbitration occurs. In connection therewith, the parties agree that the
arbitrator will present the reason for his determination in summary fashion
(i.e., in five pages or less) and will not be required to produce a detailed
legal or technical opinion.

                                                                              16

shall not affect the validity or enforceability of any other provision hereof.

     (b) ENTIRE AGREEMENT. This Agreement together with the SLA represents the
entire agreement of the parties with respect to the subject matter hereof and
cancels and supersedes any previous understanding, commitments, or agreement,
oral or written, between Licensee and Licensor, other than confidential
disclosure agreements.

     (c) WAIVER. No failure by either party to insist upon the strict
performance of any covenant, term or condition of this Agreement, or to exercise

this Agreement shall be governed by the laws of the State of Delaware, exclusive
of its choice of law provisions.

     (e) AMENDMENT. This Agreement may not be amended except in writing executed

party's consent, to a third party in the event of a change in control or any
sale, assignment, transfer or other conveyance to such third party of all or
substantially all of the business or assets of the assigning party, or (in the
case of the Licensee) any sale, assignment, transfer or other conveyance of the
Site to such third party. Subject to the foregoing, this Agreement shall be
binding on the parties and their respective successors and permitted assigns,
and such permitted assigns shall expressly agree to be bound by all the terms
and conditions herein and in the SLA. No partial assignment of the rights or
obligations granted hereunder and under the SLA shall be permitted.

     (g) COUNTERPARTS. This Agreement may be signed in one or more counterpart
copies, all of which together shall constitute one Agreement and each of which

                                    EXHIBIT B

                                 CRS PROHIBITION

     Neither Licensee nor any Affiliate (as defined below) shall (i) license or
sublicense the Licensed Software, for Low Fare Searching or Guaranteed Fare
Pricing (as defined below), to any CRS Entity (as defined below), (ii) sell
Transactions (as defined below) to or otherwise perform Transactions for any CRS
Entity, or (iii) provide Low Fare Searching data processed using the Licensed
Software to or for any CRS Entity.

As used in this Exhibit B:

     "Affiliate" shall mean, when used with respect to a specified Person,
another Person that, directly or indirectly through one or more intermediaries,
controls or is controlled by or is under common control with the Person
specified. For purposes of this Agreement, the term "control" (including, with
its correlative meanings, "controlled by" and "under common control with") shall
mean possession, directly or indirectly, of the power to direct or cause the
direction of management or policies (whether through ownership of securities or
partnership or other ownership interests, by contract or otherwise).

     "CRS Entity" shall mean (i) any of the computerized reservation systems
providers listed at the end of this Exhibit B, or any successor in interest,
assign or renaming of any such provider, (a "CRS", (ii) any Person (as defined
below) which directly or indirectly through one or more intermediaries, controls
or is controlled by or is under common control with any such provider, where the
term "control" (including, with its correlative meanings, "controlled by" and
"under common control with") shall mean possession, directly or indirectly, of
the power to direct or cause the direction of management or policies (whether
through ownership of securities or partnership or other ownership interests, by
contract or otherwise) (a "CRS Affiliate"), or (iii) any company with which any
CRS has contractual commitments for the distribution of such CRS' products and
services (a "CRS National Distribution Company"). Notwithstanding the foregoing
definition, an air carrier or a foreign air carrier (each as defined in the
United States Federal Aviation Act of 1958, as amended) shall not be deemed a
"CRS Entity" for the purposes hereof.

     "Person" shall mean any individual, corporation, partnership, limited
partnership, joint venture, limited liability company, unincorporated
association, government or regulatory body (or any agency or political
subdivision thereof) or other entity.

     "Low Fare Searching" shall mean the capability for retrieving flight

or more travel service providers for one or more bookings, including all taxes,
fees, and other charges.

     "Transaction" shall mean an individual Low Fare Searching query to the

reservations system is hosted on a CRS, provided that neither the CRS nor any
CRS affiliate or CRS National Distribution company can use the Licensed Software
to provide services using the Licensed Software or data processed using the
Licensed Software to any Person other than Licensee and its Affiliates.

though it were a party hereto. Licensed acknowledges and agrees that (i) its
breach of this Exhibit B would cause irreparable injury for which monetary
damages are not an adequate remedy, and (ii) Licensor and Amadeus shall be
entitled to injunctive and other equitable relief in the event of an actual or
threatened breach of this Exhibit B in addition to any other remedies that may
be available.

          (c) Workers' Compensation insurance, including coverage for all costs,

policies do not afford adequate protection for Licensee, then licensee shall so
advise Licensor. Thereafter, if Licensor does not furnish evidence of acceptable
coverage within fifteen (15) days, then Licensee shall have the right, in its
sole discretion, to (i) withhold payments from Licensor until evidence of such
acceptable coverage is provided, or (ii) terminate this Agreement in accordance

                                    EXHIBIT E

                          DISPUTE RESOLUTION PROCEDURES

     1. NEGOTIATION. In the event of any dispute or disagreement between the
parties with respect to the interpretation of any provision of this Agreement or
with respect to the performance of either party hereunder, account managers from
both parties shall meet for the purpose of resolving the dispute. If the account
managers are unable to resolve the dispute within five (5) business days, the
dispute shall then be submitted to the Chief Executive Officer ("CEO") of each
party (or the CEO's designee, excluding the account managers) (the
"Representatives") who shall commence meeting within five (5) business days in
order to gather and furnish to each other all essential, non-privileged
information that the parties believe germane to resolution of the matter at
issue, and to resolve the dispute. Such meetings shall extend for no more than
five (5) business days after commencement (the "Representative Negotiation
Period"). During the Representative Negotiation Period, all information
exchanged shall be limited to non-privileged information. All requests shall be
made in good faith and be reasonable in light of the time period specified for
the Representative Negotiation Period.

     2. ARBITRATION. In the event the parties are not able to resolve the
dispute through the process described above, the dispute shall be finally
settled by binding arbitration ("Arbitration") conducted expeditiously in
accordance with the rules of the American Arbitration Association (the "Rules").
The arbitration procedure set forth below shall be the parties' exclusive remedy
for all disputes arising hereunder; and PROVIDED, FURTHER, that any party may
seek judicial entry of any arbitral award. The Arbitration shall be conducted by
a single arbitrator, who shall not be an officer, director, or employee of any
party hereto or its affiliates, appointed as provided in the Rules. The
arbitrator shall not have the power to adjudicated or make an award with respect
to any matter that is not subject to the Arbitration. The arbitrator may make
interim awards and may award equitable and declaratory relief.

     3. PLACE OF ARBITRATION. Any Arbitration hereunder shall be conducted at a
mutually acceptable location in either Chicago, Illinois, USA or Boston,
Massachusetts, USA (or, if the parties are unable to agree as to which of such
cities shall be the location of Arbitration, then in a mutually acceptable
location in New York City, New York, USA).

     4. COSTS AND FEES. Each party shall, except as otherwise provided herein,
be responsible for its own expenses, including legal fees, incurred in the
course of the Representative Negotiation Period and Arbitration. The fees of the
arbitrator shall be divided evenly between the parties.

     5. EQUITABLE RELIEF. The provisions of this Exhibit shall not prevent
either party from seeking (a) equitable relief for breaches of the other party's
confidentiality obligations under this Agreement or (b) specific performance of
the other party's material breach of its obligations under this Agreement,
including, without limitation, a material breach by Licensor of its warranty and
support obligations. Both parties agree that, the existence of a dispute
notwithstanding, they shall continue without delay to carry out all their
responsibilities under this Agreement that are not affected by the dispute.

Licensor shall invoice Licensee for all fees and charges accruing under the
Agreement on a timely basis. Licensee shall have no obligation to pay any fees
or charges that Licensor fails to invoice to Licensee within thirty (30) days
following the end of the monthly billing cycle in which such fees and charges

Atlanta/Chicago", etc.), broken down by categories (i.e., "Engineering",
"Operations", etc.); (iii) the number of hours for each principal work project
included in the SOW, identifying those hours incurred by Engineering/Development
and those hours spent by Operations; and (iii) the billable rate therefor.

Where the Licensor is invoicing for professional services that do not relate to
an existing SOW but relate to work undertaken at the direction of an authorized
officer of Licensee (whether or not in writing), then the invoice will identify
(i) the authorized officer of Licensee who has directed Licensor to undertake
such work; (ii) a general description of the activities undertaken by the
Licensor during the period, broken down by categories (i.e., "Engineering",
"Operations", etc.); (iii) the number of hours spent on such work, identifying

Operations; and (iv) the billable rate therefor.

Licensee shall not be obligated to pay any invoices until receiving the
foregoing detail and documentation.
