      WHEREAS, Worldspan and Customer now desire to amend the Subscriber Entity
Agreement.

      NOW, THEREFORE, it is agreed:

by Amendments to the Worldspan Subscriber Entity Agreement dated the 1st of
January 1999, the 5th of January 2000, and the 5th of July 2000 (collectively,

      3. Customer and/or the Affiliates shall generate a minimum of [**]
Bookings through the Worldspan GDS during the Term. At the end of the Term, in
the event that the combined total of Worldspan Bookings by Customer and the
Affiliates is less than [**] Bookings, Customer shall not be deemed to be in
breach of its obligation under this paragraph provided that (i) Customer
executes an amendment extending the Term by an additional [**] (the "Additional
Booking Evaluation Period") and preserving all other terms and conditions of the
Subscriber Entity Agreement except the obligation set forth in this paragraph,
and (ii) Customer has performed all other material obligations under the
Subscriber Entity Agreement. Upon Customer's execution of such an amendment,
Worldspan agrees that the failure to generate [**] Bookings shall not (i)
constitute a breach of the Subscriber Entity Agreement, (ii) constitute the
default of any obligation of the Subscriber Entity Agreement, or (iii) give rise
to any cause of action or claim against, or liability on the part of, Customer
for any losses or damages of any kind. The parties acknowledge that the
foregoing provision has been negotiated at arms length between Worldspan and


[**] = Confidential Treatment requested for redacted portion; redacted portion
       has been filed separately with the Commission                    Page 1
<Page>

Customer and represents a reasonable compromise in the event of Customer's
failure to complete the specified obligation.

      4. Customer shall generate a minimum of [**] of Customer's Bookings in the
United States of America and Canada (USA/Canada) through the Worldspan GDS in
each Booking Evaluation Period.

      5. If Customer fails to comply with its obligations under paragraph 4 in
[**], then Worldspan may give Customer written notice that such an event has
occurred and that Worldspan is terminating the Subscriber Entity Agreement,
effective thirty (30) days from Customer's receipt of such notice.

            a) Upon a termination pursuant to this paragraph following [**],
Customer shall be liable to Worldspan for liquidated damages calculated
according to the formula set forth below:

Liquidated Damages =    The lesser of (i) the number of Expected Bookings,
                        multiplied by [**], or (ii) the amount, if any, that the
                        number of actual Bookings generated by Customer through
                        the Worldspan GDS from the beginning of the Term until
                        the effective termination date is less than [**]
                        Bookings, multiplied by [**]. For purposes of this
                        Amendment, "Expected Bookings" shall mean the average
                        number of Bookings generated by Customer through the
                        Worldspan GDS per month in the [**] months preceding the
                        event of default, multiplied by [**].

            b) Upon a termination pursuant to this paragraph following [**],
Customer shall be liable to Worldspan for liquidated damages calculated
according to the formula set forth below:

Liquidated Damages =    The amount, if any, that the number of actual Bookings
                        generated by Customer through the Worldspan GDS from the
                        beginning of the Term until the effective termination
                        date is less than [**] Bookings, multiplied by [**].

The parties acknowledge that the foregoing provision has been negotiated at arms
length between Worldspan and Customer and represents a reasonable measure of
liquidated damages in the event of Customer's default of the specified
obligations.

      6. If Customer fails to comply with its obligations under paragraph 4 in
[**], Customer shall be liable to Worldspan for liquidated damages calculated
according to the formula set forth below:

Liquidated Damages =    The amount, if any, that the number of actual Bookings
                        generated by Customer through the Worldspan GDS during
                        the Term is less than [**] Bookings, multiplied by [**].

The parties acknowledge that the foregoing provision has been negotiated at arms
length between Worldspan and Customer and represents a reasonable measure of
liquidated damages in the event of Customer's default of the specified
obligations.

      7. Customer shall use good-faith efforts to cause the Affiliates, as a
whole, to generate a minimum of [**] of the Affiliates' aggregate Bookings
globally through the Worldspan GDS in each Booking Evaluation Period. This
obligation is subject to Worldspan's geographic and vendor-specific connectivity
capabilities. Customer shall give Worldspan the opportunity to develop new
technological capabilities in order to serve the Affiliates' international
needs. Worldspan agrees that the failure of Customer to meet its obligations
under this paragraph shall not (i) constitute a breach of the Subscriber Entity
Agreement, (ii) constitute the default of any obligation of the Subscriber
Entity Agreement, or (iii) give rise to any cause of action or claim against, or
liability on the part of, Customer for any losses or damages of any kind. The
parties acknowledge that the foregoing provision has been negotiated at arms
length between Worldspan and Customer and represents a reasonable compromise in
the event of Customer's failure to complete the specified obligation.

      8. In each Booking Evaluation Period, Customer agrees to use good-faith
efforts to cause the Affiliates, as a whole, to complete [**] of their non-air
Bookings originating in countries other than USA/Canada through the


[**] = Confidential Treatment requested for redacted portion; redacted portion
       has been filed separately with the Commission                    Page 2

Worldspan GDS. This obligation is subject to Worldspan's geographic and
vendor-specific connectivity capabilities. Customer shall give Worldspan the
opportunity to develop new technological capabilities in order to serve the
Affiliates' international needs. Worldspan agrees that the failure of Customer
to meet its obligations under this paragraph shall not (i) constitute a breach
of the Subscriber Entity Agreement, (ii) constitute the default of any
obligation of the Subscriber Entity Agreement, or (iii) give rise to any cause
of action or claim against, or liability on the part of, Customer for any losses
or damages of any kind. The parties acknowledge that the foregoing provision has
been negotiated at arms length between Worldspan and Customer and represents a
reasonable compromise in the event of Customer's failure to complete the
specified obligation.

      9. Worldspan shall pay the following USA/CANADA BOOKING INCENTIVE to
Customer for each Booking generated by the Affiliates in each Booking Evaluation
Period through the Worldspan GDS in USA/Canada:

         ----------------------------------------------------------------------
</Table>

Payment shall be made no later than forty-five (45) days following the end of
each calendar quarter, with any reconciliation, if necessary, completed upon the
end of the Booking Evaluation Period. The determination of the number of
Bookings shall be made solely by Worldspan from its books and records, subject
to paragraph 14 of this Amendment.

      10. Notwithstanding the foregoing paragraph, if Customer fails to comply
with its obligations under paragraph 4 of this Amendment, the USA/CANADA BOOKING
INCENTIVE shall be reduced to [**] per air Booking and [**] per hotel and car
Booking for the Booking Evaluation Period in which Customer fails to comply. No
later than thirty (30) days following the end of the Booking Evaluation Period
in which Customer fails to comply with its obligations under paragraph 4 of this
Amendment, Worldspan shall conduct a reconciliation of the payments made to
Customer in the initial calendar quarters of the Booking Evaluation Period, the
amount owed to Customer for the final calendar quarter of the Booking Evaluation
Period, and the amount overpaid to Customer as a result of the higher
per-Booking incentives initially anticipated. No later than fifteen (15) days
after the completion of such reconciliation, Worldspan shall notify Customer of
the payment due to or from Customer. The applicable party shall make such
payment no later than thirty (30) days following the completion of the
reconciliation. The determination of the number of Bookings shall be made solely
by Worldspan from its books and records, subject to paragraph 14 of this
Amendment.

      11. The following incentives shall be determined solely by Bookings
generated by the Affiliates through the Worldspan GDS in countries other than
USA/Canada:

            a) INTERNATIONAL BASE AIR INCENTIVE. Worldspan shall pay [**] per
air Booking to Customer for air Bookings generated by the Affiliates through the
Worldspan GDS in countries other than USA/Canada.

            b) INTERNATIONAL CAR AND HOTEL INCENTIVE. Worldspan shall pay [**]
per car or hotel Booking to Customer for car and hotel Bookings generated by the
Affiliates through the Worldspan GDS in countries other than USA/Canada.

each calendar quarter. Customer shall provide documentation to Worldspan on a
quarterly basis, which in Worldspan's sole opinion, substantiates Customer's
international car and hotel Bookings. The determination of the number of

to paragraph 14 of this Amendment.

      12. Provided that Customer complies with its obligations under paragraph 4

[**] = Confidential Treatment requested for redacted portion; redacted portion
       has been filed separately with the Commission                    Page 3
<Page>

            a) In the event the Affiliates (as a whole) generate more than [**]

shall pay Customer an additional bonus of [**] no later than forty-five (45)
days following the end of the Booking Evaluation Period.

            b) In the event the Affiliates (as a whole) generate more than [**]

days following the end of the Booking Evaluation Period.

            c) In the event the Affiliates (as a whole) generate more than [**]

Worldspan shall pay Customer an additional bonus of [**] no later than [**].

      13. Worldspan and Customer acknowledge that the incentives provided in the
foregoing paragraphs are dependent on Worldspan's booking fee rates charged to
travel suppliers remaining at levels comparable to the rates charged to travel
suppliers as of the Effective Date. In the event that (i) the booking fee rates
charged by Worldspan should decrease by [**] or more compared to the rates
charged to airlines or to car/hotel suppliers as of the Effective Date due to
causes beyond the direct control of Worldspan or (ii) Worldspan, Customer, and a
travel supplier agree to implement a substantially modified pricing structure
with respect to that travel supplier, then Worldspan and Customer agree to
negotiate in good faith to revise the Subscriber Entity Agreement to conform

result in a modification to the Subscriber Entity Agreement, then Worldspan
reserves the right (i) to eliminate the Customer incentives provided for in
paragraphs 9, 10, 11, and 12 of this Amendment with respect to such Bookings, or

such incentives, Customer shall have the right to immediately terminate the
Subscriber Entity Agreement.

      14. Either party may, upon reasonable prior written notice to the other
party, request a meeting for the purpose of documenting and verifying Booking
records with respect to Customer. Each party shall be solely responsible for its
costs incurred with respect to this meeting. Each party shall make available to
the other party the documentation or records reasonably requested by the other
party to document and verify Customer's Bookings. In the event of any material
disagreement on Booking counts, Customer shall have the right to appoint an
independent third party acceptable to both parties to audit the books and
records used by Worldspan in determining Booking counts.

      15. Worldspan shall provide up to [**] hours of consulting and development
services to assist Customer with design of [**] and other issues relating to the

provide qualified individuals to provide other technical services. These
services shall be charged to Customer at the rate of [**] per hour or
Worldspan's then current standard rate for consulting services, whichever is

written documentation to Worldspan of the total number of planned, budgeted

      23. Customer and Worldspan shall use their best efforts to negotiate a

under the Subscriber Entity Agreement. In the event that an agreement cannot be
reached in such negotiations, then the Subscriber Entity Agreement shall remain
in full force and effect.

and [**] any of their successor entities.

at their respective discretion terminate services to such EU Affiliate without
penalty on giving at least ninety (90) days' prior written notice, to expire no
