                     AMENDMENT TO SOFTWARE LICENSE AGREEMENT

          AMENDMENT, made as of the 19th day of June, 2003, to that certain
Amended and Restated Software License Agreement (the "Agreement"), dated as of
May 15, 2002 by and between Orbitz, LLC, ("Orbitz") and ITA Software, Inc.
("ITA"). All capitalized terms used but not defined herein shall have the
respective meanings set forth in the Agreement.

          WHEREAS, the Agreement provides for the license by Orbitz of the
Licensed Software;

          WHEREAS, the Licensed Software, as defined in the Agreement and as
licensed by Orbitz, includes the Domestic Version but not the International
Version (as such terms are defined below);

          WHEREAS, Orbitz wishes to expand the scope of its license to include
the International Version as well as the Domestic Version;

          NOW, THEREFORE, in consideration of the foregoing the parties hereby
agree as follows:

     1.   DEFINITIONS

          The following definitions are hereby added to the Agreement:
          "International Location" means any country or territory other than the
United States, Puerto Rico, the US Virgin Islands and Canada.

          "International PNR" means a PNR that includes an origin, stop or
destination in an International Location. An International PNR "created" shall
be deemed to refer to all International PNRs created, whether or not
subsequently cancelled; I.E., "gross PNRs", not "net PNRs".

          "International Production Date" means the earlier of (i) the date
Orbitz begins using the International Version in full commercial production
(excluding, however, the use of the International Version in a "beta" or similar
testing or evaluation phase, in connection with which Orbitz may make the
International Version available to a limited number of Online Users) or (ii)
October 1, 2003.

          "International Version" means the version of the Licensed Software
that has the capability for searching flights and pricing itineraries where such
flights and itineraries include an origin, stop or destination in an
International Location.

          "License Quarter" means each calendar quarter during a License Year,
with the first such License Quarter beginning on October 1, 2003.

<Page>

     2.   DEFINITION OF LICENSED SOFTWARE

          The definition of "Licensed Software" in the Agreement is hereby
amended so as to include the International Version.

     3.   FEES AND EXPENSES

          The following fees and expenses will apply to Orbitz's use of the
International Version:

               (a)  PER-PNR FEE. Beginning on the International Production Date,
Orbitz will pay a license fee (the "International License Fee") for the
International Version of $[***] per International PNR created.

               (b)  MINIMUM LICENSE FEE. The International License Fee will be
subject to a minimum of $[***] per License Year, with the first such License
Year beginning on October 1, 2003.

               (c)  PAYMENT TERMS. The Minimum License Fee will be payable in
equal quarterly installments of $[***], in advance, with the first such payment
due on October 1, 2003. In addition, within 30 days after the end of each
License Quarter, Orbitz will certify to ITA the number of International PNRs
created during such License Quarter and the cumulative number of International
PNRs created during the current License Year. In the event that, at the end of
any License Quarter, the International License Fee (calculated pursuant to
paragraph (a) above) that would apply to the cumulative number of International
PNRs generated during such License Year exceeds the cumulative Minimum License
Fees (I.E., during the first License Year, $[***] multiplied by the number of
License Quarters then elapsed in such License Year), then Orbitz will pay ITA,
simultaneously with such certification, an amount equal to the excess of the
International License Fee, as so calculated, over the total amount actually paid
License Year-to-date by Orbitz hereunder. The obligation to make Minimum License
Fee payments during a License Year shall be suspended at such time as the
International License Fee with respect to such License Year equals or exceeds
$[***].

               (d)  DOMESTIC PRICING UNAFFECTED. The price provisions applicable
to the Domestic Version set forth in Sections 8(a) through (d) of the Agreement
will not be affected by the provisions of this Section 3 of this Amendment.

     4.   TERM AND TERMINATION OF THIS AMENDMENT

          The initial term of this Amendment shall be two years from October 1,
2003. Thereafter, it shall remain in force until terminated by either party upon
30 days' prior written notice to the other party, and the minimum International
License Fee payable for the last full or partial License Year shall be equal to
$[***] per quarter, multiplied by the number of prorated License Quarters in
such License Year.

     the Commission. Confidential treatment has been requested with respect to
     the omitted portions.

<Page>

          In addition, Orbitz will have the right, on 30 days' written notice,
to terminate this Amendment, for any reason, at any time prior to the
International Production Date. In such event, (i) Orbitz will cease use of the
International Version on or prior to the effective date of termination, (ii) all
modifications to the Agreement effected hereby will be rescinded and this
Amendment will be of no force or effect; and (iii) in the event Orbitz
subsequently wishes to license the International Version, ITA will make it
available on then-standard prices (ITA's current standard price for the
International Version is $[***] per PNR).

     5.   OPERATIONS

          The parties' current expectation is that Orbitz will operate the
computers running the International Version, and that ITA will assist Orbitz in
the set-up, installation and operation of the International Version. In such
event, ITA will work with Orbitz on an implementation plan for the International
Version, and ITA personnel will assist in executing such plan, so as to insure
an expeditious implementation of the International Version. ITA will invoice
Orbitz, and Orbitz will pay in accordance with Section 8(i) of the Agreement,
for the services of ITA's operations department in rendering such assistance.
Such services will be invoiced at ITA's standard rate (presently $[***] per
hour). In the event the parties determine that ITA, and not Orbitz, should
operate the computers running the International Version, then the parties will
negotiate an amendment to the SLA providing for the financial terms and service
levels that will apply to such operations services.

     6.   EFFECT ON AGREEMENT

          Except as specifically amended hereby, the Agreement shall remain in
all respects in full force and effect.

          IN WITNESS WHEREOF, the parties have hereunto set their hands and
seals as of the date first above written.

   SOFTWARE MAINTENANCE, DATA SERVICES AND OPERATIONS SERVICE LEVEL AGREEMENT

SOFTWARE MAINTENANCE, DATA SERVICES AND OPERATIONS SERVICE LEVEL AGREEMENT
("Agreement") entered into as of the 1st day of January, 2001, as amended on
May 15, 2002, by and between ITA Software, Inc. ("Licensor") and Orbitz, LLC
("Licensee").

1.  INTRODUCTION

This Software Maintenance, Data Services and Operations Service Level Agreement
covers standards for the provision of software maintenance, data management and
support, and operations by Licensor to Licensee, in connection with that certain
Software License Agreement dated as of July 1, 2000 between Licensee and
Licensor (the "License Agreement"). The License Agreement terminates on
September 30, 2004 (if not renewed) and this Agreement, and the pricing
contained herein, has been structured to run concurrently with the License
Agreement. Capitalized terms used but not defined herein will have the meaning
ascribed thereto in the License Agreement.

In accordance with the License Agreement, Licensor has granted to Licensee a
license to use the Licensed Software (as defined in the License Agreement) for
the purpose of enabling End Users (as defined in the License Agreement) to
obtain information and to make decisions about airline routes and schedules,
airfares and availability, as well as to search for low airfares, at Licensee's
World Wide Web site currently located at www.orbitz.com. Licensee will operate a
portion of the Licensed Software at its location in Chicago, Illinois (the
"Licensee Facility", which shall include any other location to which Licensee
may move its operations center in the future). To support Licensee, Licensor
will: (i) provide maintenance and support for the Licensed Software, pursuant to
Section 2 of this Agreement ("Maintenance Services"), (ii) provide data and data
support relating to the Licensed Software, pursuant to Section 3 of this
Agreement ("Data Services") and (iii) provide operations to effect the
Maintenance Services and the Data Services, pursuant to Section 4 of this
Agreement ("Operations Services").

2.  MAINTENANCE SERVICES

2.1    SCOPE OF SERVICES

(a) The following are the Maintenance Services that will be provided by Licensor
in connection with the Licensed Software:

Licensor shall:

       (i)     develop and provide corrections, changes, or workarounds
               ("Corrections") for any defects, errors, or malfunctions in the
               Licensed Software, including, but not limited to, any
               nonconformities with the Specifications (as defined below)

<Page>

               (collectively, "Defects"), discovered by Licensee or Licensor, on
               a timely basis, given the nature and scope of the Defect;

       (ii)    provide to Licensee all improvements, modifications and
               enhancements ("Improvements", which term will not include
               improvements, modifications or enhancements (i) which contain
               significant new or improved functionalities or (ii) which are
               developed by Licensor specifically for its other customers which
               are specific to the systems or software of such other customers
               and which Licensor does not have the right to license to its
               licensees) to the Licensed Software which Licensor shall make or
               acquire from time to time and which Licensor makes available to
               its licensees generally; and

       (iii)   provide Licensee any upgrade releases ("Upgrade Releases") to the
               Licensed Software and all new Versions and Releases of the
               Licensed Software, which Licensor makes available to its
               licensees generally; provided, however, that if any such Version
               or Release contains significant new or improved functionalities,
               Licensor shall have the right to make such Version or Release
               available to Licensee only upon the payment of additional license
               fees, or upon such other terms, as the Licensor requires of its
               licensees generally therefor. "Versions" shall be designated by a
               change in the digits to the left of the decimal point, and
               "Releases" shall be designated by a change in the digits to the
               right of the decimal point.

As used herein, "Specifications" means the functionality of the Licensed
Software described in Exhibit A to the License Agreement.

(b) Licensee shall implement all Corrections that do not materially alter or
diminish the functionality of the Licensed Software as described in the
applicable Documentation and Specifications. Licensee's failure to do so within
90 days after receipt of notice from Licensor regarding the availability of such
Corrections shall eliminate Licensor's obligation to provide Maintenance
Services until such Corrections are implemented. In addition, any modifications
to Licensor-provided configuration files or alteration from Licensor's
recommended use of configuration options shall eliminate Licensor's obligation
to provide Corrections or other Maintenance Services for that portion of the
software affected thereby, unless such modifications by Licensee were
occasioned, following consultation between Licensee and Licensor, by Licensor's
failure to modify or correct the Licensed Software as required hereunder or
under the License Agreement.

(c) In the event that changes in industry-standard practices and/or data formats
(such as ATPCO file formats, ATPCO processing, SSIM schedule formats and
government mandates regarding taxes and passenger facility charges (PFCs))
prevent the Licensed Software from functioning as specified in the License
Agreement or Specifications, the Licensor shall deliver updates to the Licensed
Software to permit operation of the Licensed Software in a manner equal to the
functionality described in the License Agreement and Specifications. Such
updates will be considered "Improvements" for the purposes of this Section 2,
and Licensor shall deliver such Improvements to Licensee

<Page>

within a reasonable time prior to the effective date of such industry change so
that such Improvements may be implemented by the effective date of such change.
Licensee shall implement any Improvements delivered pursuant to this paragraph
(c) as soon as practicable after delivery thereof.

(d) Licensor will provide Licensee any revisions to the existing Documentation
developed or necessary to reflect all Corrections, Improvements, Upgrade
Releases, Versions or Releases for the Software.

(e) All computer programs delivered pursuant to the Maintenance Services shall
be considered "Licensed Software" and subject to all the terms and conditions of
the License Agreement.

(f) Licensor shall provide Maintenance Services directly to Licensee but not to
End Users.

(g) Licensor shall at all times provide Maintenance Services for at least the
current and one (1) previous Release of the Licensed Software; provided, that
Licensor's obligation to maintain a previous Release will terminate 120 days
after the current Release was made available to Licensee; and provided further,
however, that in the case of Improvements delivered pursuant to paragraph (c),
Licensor will not be obligated to provide Maintenance Services with respect to
any prior Release which does not incorporate the industry changes comprised in
such Improvements.

2.2    MAINTENANCE

2.2.1  BASIC MAINTENANCE

The Licensor shall maintain a technical support entry point in Massachusetts,
identified by a dedicated phone number, fax number and e-mail address, which
will be staffed by knowledgeable employees capable of providing technical
assistance regarding the Licensed Software, its functionality, databases,
operations, utilities and supporting documentation. Such telephone or e-mail
assistance will be available to the Licensee on a daily basis during regular
working hours (9:00 a.m. to 6:00 p.m. Eastern time Monday through Friday). This
technical support entry point will also coordinate problem resolution and keep
the Licensee apprised of efforts to remedy any problem situation until complete
restoration of the service. First line of support will be the Licensee's Help
Desk, who will contact and escalate problem to Licensor when necessary.

2.2.2  ENHANCED MAINTENANCE

Enhanced Maintenance will comprise the following: the Licensor shall provide
on-call coverage outside the technical support working hours described above, 24
hours/day, 7 days/week, to support urgent problem resolutions of Severity 1 and
2 Problems (as

<Page>

defined in Section 2.3); provided that during the 72 hours prior to major
launches of the site (which will not occur more than four times per year)
Licensee may report problems which relate to such launch during non-business
hours even though such problems are not otherwise within the definitions of
Severity 1 or Severity 2. This on-call coverage will be provided via a dedicated
pager number, carried by knowledgeable employees of the Licensor. During normal
working hours, problem reporting will be through the Basic Maintenance entry
point, but the Licensor's response shall be in accordance with Enhanced
Maintenance service standards. In addition, upon request of Licensee, Licensor
shall provide on-site support within twenty-four (24) hours or within a mutually
agreed time frame between the parties where telephone support fails to correct
any Defect within the target time period set forth in Section 2.3. In such
event, Licensor shall provide qualified personnel to work exclusively to correct
such Defects until the same is corrected.

2.3    PROBLEM CLASSIFICATION

Licensor shall respond to and use its reasonable commercial efforts to resolve
problems in accordance with the severity levels indicated below, which severity
levels shall be determined in good faith by Licensee.

<Table>

</Table>

In addition to the foregoing, in the case of Severity Level 2 errors, Licensor
will use reasonable commercial efforts to acknowledge receipt of Licensee's
error report within 30 minutes; and in the case of Severity 3 and 4 errors
(which as set forth above may only be reported during normal business hours),
Licensor will use reasonable commercial efforts to acknowledge receipt of
Licensee's error report within 60 minutes (or, in the case of error reports
received during the last 60 minutes of the business day, within the first 60
minutes of the following business day).

Severity 1 - Mission-Critical Impact:
The system operating the Licensed Software is rendered inoperable due to system
software failure and thus cannot perform and return responses to fare/schedule
queries. Under Enhanced Maintenance, all resources shall be applied 24 hours/7
days a week until the problem is resolved; provided that in the event that
Licensee's system is "rolled back"

-----

***  Certain information on this page has been omitted and filed separately
     with the Commission. Confidential treatment has been requested with respect
     to the omitted portions.

<Page>

and functionality is returned to a level such that it is no longer within the
definition of Severity 1 (although functionality may still be down, corrupted or
severely degraded), then the problem will be reclassified as a Severity 2
problem. Initial response and problem resolution target will be according to the
chart set forth above.

Severity 2 -High Systems Impact:
Availability feed from the Atlanta Facility is interrupted for a period
exceeding two hours, or availability information related to more than four
carriers is interrupted for a period exceeding four hours. For Enhanced
Maintenance, resources shall be applied 24 hours/7 days a week until the problem
is resolved. Initial response and problem resolution target will be according to
the chart set forth above.

[***]

[***]

Notwithstanding the foregoing definitions, problems caused by or arising from
the following will not be considered "problems" for the purposes hereof and will
not be subject to Licensor's obligation to provide Maintenance Services: (i)
failure of a Data Provider (as defined in Section 3.1(d)) to provide data in a
timely fashion; (ii) failure of telecommunications hardware or equipment; (iii)
failure or unavailability of the Worldspan system; (iv) failure of an airline
carrier to provide availability information; (v) Force Majeure (as defined in
Section 7.4).

In the event Licensee has elected not to receive Enhanced Maintenance, then the
response times and problem resolution targets (i.e., the hours during which
Licensor will be obligated to work on problem resolution) will be restricted to
normal working hours (9:00 am to 6:00 pm EST, Monday through Friday).

2.4    STANDARD OPERATING PROCEDURES

The procedures for reporting, diagnosing, tracking and responding to problems
are set forth in Licensor's standard operating procedures for Licensee ("SOP"),
which is attached to this Agreement as APPENDIX A, as it may be amended by the
parties from

-----

***  Certain information on this page has been omitted and filed separately
     with the Commission. Confidential treatment has been requested with
     respect to the omitted portions.

<Page>

time to time; provided, that Licensor will give Licensee reasonable prior notice
of any anticipated major changes to the SOP.

2.5    CHANGE MANAGEMENT

The parties shall develop a mutually agreeable change management process. At a
minimum, such process shall require Licensor to notify Licensee and obtain
Licensee's approval prior to implementing any material changes to the services
provided by Licensor hereunder or any changes which could materially affect
Licensee's use of the Licensed Software as contemplated in this Agreement and
the License Agreement.

2.6    MAINTENANCE STANDARDS

Licensor shall use its best commercially reasonable efforts to meet the response
times and resolution targets set forth in this Section 2.

3.  DATA SERVICES

3.1    SCOPE OF SERVICES

(a) Licensor maintains its data center in the Exodus Communications facility in
Waltham, Massachusetts (the "Waltham Facility", which shall include any other
location to which Licensor may move its data center in the future), from which
Licensor manages data feeds for schedule and faring data and provides such data
to Licensee for use with the Licensed Software. Licensor currently receives fare
data from Airline Tariff Publishing Company ("ATPCO") and schedule data from
Innovata, LLC ("Innovata"). Licensor also receives availability data through the
Worldspan GDS ("Worldspan") and maintains an availability cache at the Waltham
Facility for the purpose of providing availability data to its licensees.

(b) In response to a specific request from Licensee, Licensor has established a
facility at Worldspan in Atlanta, Georgia (the "Atlanta Facility", which shall
include any other location to which Licensor may in the future move its data
center for receiving availability data and operating an availability cache,
provided that Licensee shall not be obligated to pay the monthly fixed charge
set forth in Section 6.4.1 in the event such facility is moved from Atlanta,
Georgia), at which Licensor receives availability data and operates an
availability cache for the provision of availability information to the Licensed
Software. Licensor provides availability data from such availability cache to
another availability cache (which is part of the Licensed Software) operated at
the Licensee Facility. Licensor will also utilize the Waltham Facility as a
backup for availability data in the event the Atlanta Facility is unable to
communicate directly with the Licensee Facility.

(c) The operation of the Atlanta Facility and the Waltham Facility (including
all software running in such facilities) are the sole responsibility of Licensor
and the operation of the Licensee Facility (including the Licensed Software) is
the sole responsibility of Licensee.

<Page>

(d) As part of the data management services provided hereunder, Licensor will
(i) receive and manage downloads of fare and schedule data from ATPCO and
Innovata, respectively (or in each case from such other commercially reasonable
industry accepted sources as the parties may mutually agree upon, referred to
herein (together with Worldspan) as "Data Providers"), (ii) process such data
such that it is in a form suitable for use with the Licensed Software, (iii)
receive availability data from Worldspan and maintain the availability cache at
the Atlanta Facility (and, for backup purposes, at the Waltham Facility), and
(iv) transmit such availability, fare and schedule data to the Licensee Facility
as frequently as it receives such data from the relevant Data Providers. In the
event that Licensee desires Licensor to change a particular Data Provider for
purposes of providing services hereunder, Licensor shall consult with Licensee
to determine whether Licensor should make such a change.

3.2    DATA PROVIDERS

Licensor has in place and will use its best efforts to maintain legal agreements
with Data Providers for the provision of availability, schedule and fare data
for the operation of the Licensed Software. Furthermore, Licensor believes that
its commercial arrangements presently in effect with Data Providers should
enable Licensor to provide services in accordance with the terms of this
Agreement. However, Licensee acknowledges and agrees that such Data Providers
are third parties which are not in Licensor's control and which are subject to
delay or failure. While Licensor agrees, as part of its obligations under this
Agreement, to receive, load and manage such data, Licensor does not warrant the
accuracy of such data. In addition, Licensor disclaims any and all liability
resulting from or related to Data Providers' failure to provide data to Licensor
in a timely fashion. In the event a Data Provider breaches the terms of a legal
agreement with Licensor, and such breach has an adverse effect on Licensee,
Licensor shall, upon Licensee's request, consult with Licensee as to Licensor's
enforcement of its rights under such agreement; however, Licensor will retain
complete discretion as to what, if any, action to take as a result thereof.

4.  OPERATIONS SERVICES

4.1    WALTHAM FACILITY AND ATLANTA FACILITY

Licensor will operate and maintain the Waltham Facility and the Atlanta
Facility. Such operation and maintenance will include, without limitation, the
acquisition, installation, maintenance, upgrading, monitoring and all aspects of
the operation of all computer hardware and equipment, and all services related
thereto, for the Waltham Facility and the Atlanta Facility necessary in
connection with the provision by the Licensor of the Data Services provided
hereunder.

<Page>

4.2  COMMUNICATIONS

The Licensor will receive data at the Atlanta Facility and the Waltham Facility
and transmit data from from such facilities via communications channels which
may include the Internet, a virtual private network or dedicated point-to-point
circuits. Licensor shall at all times maintain agreements for high speed
connections for the receipt and transmission of such data (except that Licensee
acknowledges that Licensor does not have direct connections to ATPCO or Innovata
and receives data from such Data Providers via a high-speed internet
connection).

(a) All hardware, software and services associated with communications between
the Atlanta Facility and the Licensee Facility, including maintenance thereof,
will be the responsibility of Worldspan. The cost of such services from
Worldspan will be for the account of Licensee and Worldspan will invoice
Licensee therefor directly. Such hardware, software and services will not be
included within any of the service level or support commitments contained in
this Agreement.

(b) All hardware, software and services associated with communications between
the Waltham Facility and the Licensee Facility, and between the Atlanta Facility
and the Waltham Facility, including maintenance thereof, will be provided by the
Licensor and charged to Licensee pursuant to the provisions of Section 6.4.2
hereof.

(c) Licensee expressly acknowledges that the flow of data to or from the Atlanta
Facility or the Waltham Facility will depend in large part on the performance of
hardware, software and services provided or controlled by third party
communications providers and by Worldspan. Licensor disclaims any and all

third party communications providers and/or Worldspan.

5.  PERFORMANCE SERVICE LEVELS

5.1    DATA DELIVERY.

Licensor will exercise reasonable commercial efforts to deliver data in
accordance with Section 3.1. Failures to deliver data will be subject to the
following:

   (a) In the event Licensor fails to deliver schedule data at the scheduled
       delivery time, such failure will be treated as a "Severity 4" error. If
       such failure has not been remedied within twenty-four hours of the later
       of (i) the scheduled delivery time or (ii) the time Licensor actually
       receives such data from the Data Provider thereof, then such failure will
       be treated as a "Severity 2" error.
   (b) In the event Licensor fails to deliver fare data at the scheduled
       delivery time, such failure will be treated as a "Severity 4" error. If

       delivery time for the next scheduled delivery or (ii) two hours of the
       time Licensor actually receives such data from the Data Provider thereof,
       then such failure will be treated as a "Severity 2" error.

<Page>

   (c) Any failure to transmit availability data will be covered by the Severity
       definitions contained in Section 2.3.

is being paid by Licensee pursuant to this paragraph.

Notwithstanding the foregoing, in the event Licensee may negotiate with
Worldspan, L.P. or another third party for relief from or abatement of such
fee, Licensor shall abate or adjust such fee as directed by Licensee;
provided, however, that if obtaining such relief or abatement necessitates a
change in the availability vendor, the parties shall mutually agree upon the
costs associated with such change.

6.3.2  ADDITIONAL CHARGE FOR AVAILABILITY DATA

   (a) In the event Licensee uses Worldspan availability data but ceases to
       process in the Worldspan system substantially all its air travel
       transactions which are generated from the Licensed Software, then
       Licensee will pay an additional charge of $[***] per PNR (as defined in
       the License Agreement) created by Licensee's use of the Licensed
       Software; provided, that in the event Licensee may negotiate with
       Worldspan a relief from or abatement of such fee, Licensor will abate
       such fee if so directed by Worldspan.
   (b) If the charge described in paragraph (a) is applicable, Licensee will
       certify to Licensor, within 30 days of the end of each calendar quarter,
       the number of PNRs created on Worldspan during such quarter.
       Notwithstanding the provisions of Section 6.5, Licensee will pay such
       charge simultaneously with its delivery of such certification.

Licensor in its pricing to its licensees resulting from such a cost increase.

6.4    OPERATIONS SERVICES

6.4.1  ATLANTA AND WALTHAM FACILITIES

Licensor will charge Licensee in respect of the costs for establishing and
maintaining the Atlanta Facility and a rateable portion of the costs for
maintaining the Waltham Facility. Such charge consists of (i) a single, one-time

6.4.3  OTHER COSTS

In the event that Licensor's personnel are obligated to travel outside of the
Greater Boston area in connection with the provision of Maintenance Services,
Data Services or Operations Services pursuant to this Agreement, Licensee will
pay Licensor, with respect to such travel, all out-of-pocket expenses thereof;
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 policy regarding such reimbursable
expenses. Licensor agrees to provide Licensee with access to such original

       the Licensed Software, subject to the provisions of Section 6(b) of the
       License Agreement.
   (c) Licensee may, upon one year's prior written notice (or such shorter
       notice period, no less than 90 days, equivalent to the then-remaining

       Facility) to Licensor, terminate Operations Services under Section 4.1

7.4    FORCE MAJEURE

Licensor will not be responsible or liable for, and will be excused from, any
non-performance or delay in the performance of any of its obligations under this
Agreement if and to the extent that such non-performance or delay (i) is caused

changes in law, regulation or government policy, or non-performance by any third
party (including vendors or suppliers), or any other factor beyond the control
of Licensor, whether or not foreseeable ("Force Majeure"), and (ii) could not
have been prevented by Licensor's taking normal and customary precautions. In

obligations as soon as feasible.

a third party. Licensor shall reimburse Licensee for all costs incurred by
Licensee in effecting such correction, less the amount of any Service Level
Credit received by Licensee pursuant to Section 6.6 hereof. In the event such
failure relates to Severity 3 or Severity 4 errors, this Section will only apply
if such errors are chronic or continuous.

7.9    MISCELLANEOUS

jurisdiction to be invalid or unenforceable, such determination shall not affect
the validity or enforceability of any other provision hereof.

Licensee and Licensor with respect to the subject matter hereof.

provisions.
