Exhibit A
Amendment to Custom Terms and Conditions Attachment
(Galileo Services) - North America

The Custom Terms and Conditions Attachment, as previously amended (the
“Attachment”) is amended as follows:

Removal from Paragraph F

The following two ARC numbers are removed from the table in the Attachment at
Paragraph F entitled Cheaptickets ARC Numbers:

44574423
44576641

Collectively, the above ARC Numbers are the “OFB ARC Numbers,” and each (***)
(“Carrier”) segment generated by Orbitz for Business using these OFB ARC Numbers
is a “Carrier Segment on OFB.”

Segment Incentive for Carrier Segments generated by Orbitz for Business

Effective as of July 1, 2013, Galileo will pay Subscriber $(***) for each
Carrier Segment on OFB made through the Galileo Services each calendar month,
and $(***) for each Carrier Segment on OFB made through the Worldspan Services
each calendar month. Subscriber will not be obligated to pay Galileo any Program
Fees, opt-in fees, content access fees or other fees or amounts relating to any
Carrier Segment on OFB, including without limitation any amounts associated with
Carrier Segments generated by the OFB ARC Numbers.

Retroactive Nature

Because of the retroactive nature of the effective date of the Segment Incentive
payments and related changes in the paragraph above, Travelport will use
commercially reasonable efforts to reimburse Subscriber, within 60 days
following the execution of this Amendment by both parties, an amount equal to
the total of any and all Program Fees, opt-in fees, content access fees and
other fees and amounts relating to each Carrier Segment on OFB, including
without limitation any amounts associated with Carrier Segments generated by the
OFB ARC Numbers, paid by Subscriber from such effective date through the signing
date of this Amendment.

Securities and Exchange Commission. Confidential treatment has been requested
with respect to this omitted information.
