|                                  | 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.

|                            | 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.

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 notice.
