Exhibit 10.4

AGREEMENT
—PROJECT CERVANTES—

 
This Agreement is made effective as of this 3rd day of March, 2006 by and
between Amadeus Global Travel Distribution, S.A. ("Amadeus") and Sabre Inc.
("Sabre"), hereafter referred to in the singular as Party or GDS Party or in the
plural as Parties or GDS Parties.
Preamble
Whereas, it is the objective of GDS operators (i) to provide travel agencies
with the widest possible inventory of travel information in general and air
travel information in particular; and (ii) to enable in turn travel providers
access to the greatest number of travel agencies, both for the benefit of the
consumer;
 
Whereas, on occasion a GDS may not have access to book travel on a given
airline, whilst such access may be available to the other GDS;
 
Whereas, the GDS Parties especially wish to protect travel agents that use their
systems from potential disruption of their businesses in the event that an
airline suspends participation in a GDS Party's reservation system;
 
Whereas, the GDS Parties wish to provide a framework for remedying the lack of
access to bookings by enabling one another to complete bookings on airlines
which do not participate in their system, with a view to enhancing and improving
their offerings to travel agencies and consumers;
 
NOW THEREFORE, the Parties agree as follows:
Clause 1—Purpose of the Agreement
To enable each GDS Party to gain access to the other GDS Party's multiple
reservation system, on a reciprocal basis, with the objective of allowing the
GDS Party that requests such access to enable its agents to book on airlines
that do not participate in the requesting GDS Party's reservation system.
Clause 2—Definitions
For the purposes of this Agreement, the following terms shall have the meaning
ascribed below.
—"Agreement"
shall mean this Agreement, as amended or supplemented from time to time,
including the attachments to this Agreement and amendments or supplements
thereto;
—"Retail GDS"
shall mean the GDS Party requesting from the Content Back-Up GDS access for its
Retail GDS Travel Agents to the inventory of a Non-Retail GDS Airline;
—"Content Back-Up GDS"
shall mean the GDS Party that grants the Retail GDS, solely at the latter's
request, access to the inventory of a Non-Retail GDS Airline. The Content
Back-Up GDS enables the Retail GDS Subscribers to complete a booking on the
Non-Retail GDS Airline, invoices and collects subsequently the booking fee
contractually due from that airline;
—"Non-Retail GDS Airline"
shall mean an airline which supplies its air travel information to the Content
Back-Up GDS and does not participate in the Retail GDS;
—"Retail GDS Subscriber(s)"
shall mean the travel agency subscribers of the Retail GDS;      

--------------------------------------------------------------------------------

—"Confidential Information"
shall mean information, not generally known in the relevant trade or industry,
which was received by the Retail GDS from the Content Back-Up GDS or conversely
by the Content Back-Up GDS from the Retail GDS in order to implement the
provisions of this Agreement and which relates solely and exclusively to
technical information necessary to achieve the aims of this Agreement.
Confidential Information does not include information (i) that is already known
to the other Party at the time of disclosure and not covered by a separate
agreement; and/or (ii) that becomes publicly available (other than due to a
breach by the receiving Party); and/or (iii) that is rightfully received by the
receiving Party from a third party without an obligation of confidentiality.
Clause 3—Terms of Access
Upon sole request by the Retail GDS, the Content Back-Up GDS shall take all
reasonable efforts to provide access to the Retail GDS within 24 hours (or as
soon as possible thereafter) for the purpose of enabling the Retail GDS
Subscribers to complete a booking on a Non-Retail GDS Airline.
 
The Content Back-Up GDS shall activate such access, subject to the following
terms and conditions:
 
—
Content Back-Up GDS grants Retail GDS access to its reservation system to enable
the Retail GDS Subscribers to complete a booking through the Retail GDS, which
access shall be comparable in speed and convenience to that granted by the
Content Back-Up GDS to its own subscribers. For greater certainty, under this
obligation, the Content Back-Up GDS shall provide no less favorable treatment in
terms of priority in processing the message traffic on behalf of the users of
the Retail GDS than it provides to direct subscribers of its GDS.
 
—
Access granted to Retail GDS Subscribers is limited to searching air travel
information provided by Non-Retail GDS Airlines and making a booking on those
airlines.
 
—
The Retail GDS may request that access as described above be terminated with
respect to a Non-Retail GDS Airline at any time and at its sole discretion.
 
The Content Back-Up GDS will be entitled to refuse requests for access as above
defined in relation with carriers that do not participate in the Retail GDS at
the time of execution of this Agreement, including in particular where it can
establish that such access would be contrary to any of its existing commitments.
Notwithstanding anything to the contrary set forth in this Clause 3 or elsewhere
in this Agreement, the Content Back-Up GDS shall not be in breach of this
Agreement or in any way liable to the Retail GDS or any Retail Subscribers if
the Content Back-Up GDS does not provide the Retail GDS access to the Content
Back-Up GDS' reservation system in accordance with this Clause 3 because the
provision of such access is prohibited by an injunction (whether temporary or
permanent) or other order of a court of competent jurisdiction or by applicable
law; provided, that the Content Back-Up GDS has used commercially reasonable
efforts to defend against the imposition of any such injunction or other court
order.

prevent unauthorized access to or improper use of the system of the Content
Back-Up GDS. In the event that the Content Back-Up GDS reasonably considers that
the Retail GDS is causing or allowing to be caused an abuse or misuse of its
system, it may suspend such access or terminate the agreement. Improper use
shall include, but is not limited to, generating message activity with the
system of such speed or volume that is likely to lead to malfunctions or
degradation of system performance.
Clause 7—Confidentiality
Each Party agrees that it will not, at any time, disclose to others, use for its
own benefit or otherwise appropriate or copy any Confidential Information of the
other Party, except as permitted under this Agreement.

Agreement shall not include commercial sensitive information, such as: (i) trade
secrets, prices, customers, market positions, production plans, product
development; and/or (ii) business plans, sales or marketing methods, methods for
doing business, customer lists or requirements, and supplier information; and/or
(iii) any other sensitive market information concerning the products of the
parties and shall be limited to technical information in accordance with the
definition of Confidential Information.
 
In order to avoid the passage of any price information between the Parties, both
will adhere to the procedures reflected in Attachment 3 (Payment Confidentiality
Provisions) hereto.
Clause 8—Duration and Termination
This Agreement shall be effective for a period of one (1) year.

Following the expiration of the original term specified above, this Agreement
shall be automatically renewed for successive one (1) year periods, unless
written notification is sent by either Party to the other at least ninety (90)
days prior to expiration of the then-current term.
 
In addition to any other termination rights that either Party may have according
to this Agreement, the non-breaching Party may terminate this Agreement upon
giving thirty (30) days written notice provided such termination is based on a
material breach of the other Party's obligations, and provided further that such
material breach has not been cured within fifteen (15) days of receipt of such

Attachment 3
Confidentiality Provisions

        The Parties shall institute appropriate and effective safeguards to
assure that payments received by the Retail GDS, and information concerning such
payments, for bookings made in the Content Back-Up GDS on any Non-Retail GDS
Airline do not even inadvertently disclose to personnel of the Retail GDS with
any role in setting that GDS's airline sales or pricing policies any data that
would enable such personnel to determine or approximate the booking fees charged
to any particular airline by the Content Back-Up GDS. In particular, and unless
and until replacement safeguards are expressly agreed by the Parties in writing,
then each Party in its role as a Retail GDS shall:

1.Permit only executives from within its Finance or Internal Auditorganizations
("Named Finance Person(s)") to view the detail underlying the financial flows
between the Content Back-Up GDS and the Retail GDS to the extent such detail
does disclose the source, nature, or amount of any payment made by the Content
Back-Up GDS.

2.Require each Named Finance Person to sign a non-disclosure agreement that
(a) forbids the disclosure of information concerning any amount paid by the
Content Back-Up GDS to any other person, except (i) to any other Named Finance
Person or, upon their request, to the Retail GDS's external auditors, or
(ii) where disclosure is required in any judicial or administrative proceeding,
and (b) includes termination as a penalty for any violation of such
non-disclosure agreement.

3.Require each Named Finance Person to certify every 12 months following the
implementation of this Agreement his or her compliance with the non-disclosure
obligations described in paragraph 2 above.

In its role as a Retail GDS, each Party shall have the right to audit at least
once per calendar quarter, using, at its option, either an external auditor or a
member of its internal audit team that is a Named Finance Person, the relevant
books and records of the other Party to verify the accuracy under this Agreement
of amounts paid to it by the other Party; provided, however, that any such
external or internal auditor shall be permitted to disclose the results of his
or her findings only to one or more Named Finance Persons of the Retail GDS.
