         2.2      SUBCONTRACTORS. Orbitz may subcontract its performance of the
Services to one or more Subcontractors, upon thirty (30) days' prior written
notice to Airline. Airline may object to use of such Subcontractor by providing
written notice to Orbitz within ten (10) days of receipt of notice from Orbitz
that it intends to use such Subcontractor. In such event, the Relationship
Managers will meet to resolve any issue related to such Subcontractor. Should
the Relationship Managers be unable to resolve any issue related to such
Subcontractor, Orbitz shall either perform the Services itself or select a
different Subcontractor to perform the Services. Prior to performing any
Services, each Subcontractor must execute a written agreement with Orbitz
containing protections for the Airline Information the terms of which are at
least as protective as the terms and conditions set forth in this Agreement.
Orbitz shall remain primarily liable for work performed by any Subcontractor.

         2.3      SCHEDULE. Orbitz will use its commercially reasonable efforts
to perform the Pre-Launch Development Services in accordance with the Schedule.
During the course of performance of the Pre-Launch Development Services, Airline
and Orbitz may periodically modify the Schedule for mutual convenience upon the
mutual written agreement of the parties. Any such modification will be effective
only if expressly approved in writing by both Relationship Managers pursuant to
Section 7. Airline acknowledges that modifications to the Schedule may result in
additional costs or charges for any agreed upon modifications to the Pre-Launch
Development Services.

         2.4      ANTICIPATED DELAYS. Airline and Orbitz will immediately notify
each other if either party anticipates a delay in completing the Pre-Launch
Development Services according to the Schedule. Any such notice will identify
the source and expected length of the delay and its potential impact on the
Pre-Launch Development Services. Upon receipt of such notice, the Relationship
Managers will promptly seek in good faith to determine the potential impact and
take the steps that may be available to avoid or minimize the anticipated delay
and its impact on the Schedule.

         2.5      FACILITIES. Airline will provide Orbitz with access to those
portions of Airline's facilities that Orbitz may reasonably require to perform
the Services. Such access will be provided at mutually convenient times during

such rules and regulations have been communicated to Orbitz.

         2.6      COMPLIANCE. Airline agrees not to use and will take reasonable
measures to prevent its end users from using the Orbitz Software or the Services
(i) to disseminate (A) unsolicited, unlawful, harassing, defamatory, abusive,

communications or other information, (B) any messages, e-mail communications or
other information that infringe or violate any other party's proprietary rights,

defamatory, abusive, threatening, obscene, harmful, tortious or libelous
purposes, or (iii) intentionally to disrupt the resources, computer systems and
computer networks of Orbitz or its Subcontractors. Airline agrees to post a
mutually acceptable privacy policy, copyright infringement policy and end user
compliance policy on the Website and to comply with the terms and conditions of
such policy.

Specifications or the Schedule will be effective unless expressly approved by
the


                       CONFIDENTIAL               Page 4

<Page>

primary or alternate Relationship Managers of both parties pursuant to
Section 7. Each Relationship Manager will appoint Project Managers to manage
specific projects under this Agreement. The Project Managers will serve as the
primary interface points between the parties with respect to such projects.

         3.2      STATUS REPORTS. The Orbitz Relationship Manager will provide
the Airline Relationship Manager with periodic status reports on Orbitz's
progress during the performance of the Pre-Launch Development Services. Prior to
the Development Completion Date, the Relationship Managers will meet at least

Following the Development Completion Date, the Relationship Managers will meet
at least once per quarter to discuss the Hosting and Support Services.

         3.3      PROJECT PROBLEMS. In the event of any actual or potential
problem or delay in the Pre-Launch Development Services or the Hosting and
Support Services, the Relationship Managers will discuss the relevant sources,
possible remedies and potential impact on the Pre-Launch Development Services or
the Hosting and Support Services at the next scheduled status meeting or, at
either Relationship Manager's request, an emergency meeting. To assist in such
discussions, each Relationship Manager may invite any applicable Project
Managers or other persons to the scheduled or emergency meeting. If a
modification of the Specifications or the Schedule is required as a result of
the problem or delay, the Relationship Managers will follow the procedures
specified in Section 7.

         3.4      PROJECT MANAGERS. Airline may object to the appointment of an
Orbitz Project Manager who, in the opinion of Airline, reasonably and legally
exercised, does not meet Airline's qualifications, by providing notice of its
objection to Orbitz in writing, specifying such objection in reasonable detail.
In such event, the Relationship Managers will meet to resolve any issue related
to such Project Manager. Should the Relationship Managers be unable to resolve
any issue related to such Project Manager, Orbitz shall appoint a different
Project Manager.

4.       PRE-LAUNCH DEVELOPMENT

         4.1      PRE-LAUNCH DEVELOPMENT SERVICES. Orbitz will use its
commercially reasonable efforts to provide Airline with dedicated resources to
perform the Pre-Launch Development Services and will use its commercially
reasonable efforts to develop the Airline-Specific Software and the Core
Software described in the Specifications. Airline will promptly respond to
Orbitz's requests for information regarding such efforts and will provide Orbitz
the assistance that Orbitz may reasonably require to complete the Pre-Launch
Development Services. Upon completion of such development efforts, Orbitz will
make the Orbitz Software available to Airline for testing.

         4.2      FUTURE DEVELOPMENT SERVICES. From time to time during the term
of this Agreement, Airline may request technical or functional modifications to
the Orbitz Software in addition to or in lieu of the requirements set forth in
the Specifications. Any such request will be processed according to the
procedures set forth in Section 7. Orbitz will perform any such additional
services upon which the parties mutually agree at the rates set forth in Exhibit
D.

         4.3      TESTING. Following receipt of Orbitz's notice that the Orbitz
Software, and any Update thereto, is ready for testing, Airline will test the
Orbitz Software, or any Update, within the time period set forth in the
Schedule, or any Order, to determine whether it substantially conforms to the
Specifications. If the Orbitz Software substantially conforms to the
Specifications, Airline will provide Orbitz with written notice that the Orbitz
Software, or any Update, is accepted. If the Orbitz Software or Update fails to
substantially conform to the Specifications, or Documentation, Airline will
provide Orbitz with a written report of the non-conformity, within thirty (30)
days after the notice that the Orbitz Software or Update is ready for testing,
specifying such non-conformity in reasonable detail. Upon receipt of a
non-conformity


                       CONFIDENTIAL               Page 5

<Page>

report, Orbitz will either promptly correct and resubmit the Orbitz Software or
Update for re-testing or, if the parties mutually agree that such reported
non-conformity is actually a modification from the agreed upon Specifications,
or other Documentation, the parties shall agree that such reported
non-conformity is actually a Change Request, to be handled pursuant to Section
7. Following the correction of any non-conformity, Airline shall again inspect
and evaluate the Orbitz Software or Update and conduct all necessary tests to
determine whether the non-conformity has been corrected. Upon confirming that
the non-conformity identified by Airline has been corrected, Airline shall
accept the Orbitz Software or Update as specified herein. In the event that
Airline fails to issue a report of non-conformity within such thirty (30) day
period, the Orbitz Software or Update will be deemed to be accepted.

         The test period shall be suspended during periods when Orbitz is
attempting to correct any non-conformities. Following re-delivery of a
correction to Airline under no circumstances shall Airline have less than ten
(10) days to complete testing.

         4.4      FAILURE TO DELIVER CONFORMING SOFTWARE. In the event that
Orbitz fails to deliver to Airline a version of the Orbitz Software
substantially in conformance with the Specifications within sixty (60) days of
the Launch Date and Orbitz is primarily responsible for such failure, then
Airline will not be charged for any development efforts performed by Orbitz or
its Subcontractors following such sixty (60) day period with respect to the
Pre-Launch Development Services and Orbitz will refund Pre-Launch Development
Fees actually paid to Orbitz for the Pre-Launch Development Services, in
accordance with refund policy set forth in Exhibit D. In the event that Orbitz
is not primarily responsible for such failure, no refund will be due.
Notwithstanding the foregoing, Orbitz agrees that it shall provide written
notice to Airline of any circumstances that would prevent Orbitz from delivering
conforming Orbitz Software and if such notice is not provided, Orbitz will be
deemed to have waived its argument that any performance failure under this
Agreement was attributable to Airline and Orbitz will be deemed primarily
responsible for such failure.

         4.5      MIGRATION. Orbitz and Airline will develop a mutually agreed
upon plan to migrate the provision of online travel booking services from
Airline's current online travel booking provider to Orbitz. Such migration will
be completed prior to the Launch Date. Airline will use its commercially
reasonable efforts to cause its current online travel booking services provider
to cooperate with such migration. Airline will obtain from such provider and
deliver to Orbitz the customer registration database, and will secure any rights
necessary for Orbitz to convert and use such customer registration database to
provide the Services. Both parties will use reasonable best efforts to ensure a
smooth and seamless transition from Airline's current online travel booking
provider to Orbitz. [***]

         4.6      INTERFACE TO PARTITION. With respect to any connectivity
interface that is required under the Specifications, the parties acknowledge
that Orbitz's obligations to develop such connectivity interface is expressly
dependent upon the cooperation of Worldspan, Airline's third party computerized
reservation system provider, or any other GDS selected by Airline, and Airline.
Airline will provide Orbitz with any and all information and assistance
reasonably requested by Orbitz to develop and maintain a connectivity interface
with the applicable computerized reservation system. Orbitz will not be
responsible for any delays caused by the computerized reservations system
provider's failure to cooperate with Orbitz.

               the event that Airline provides hotel and car reservation

correct, then Airline will within thirty (30) days of receipt of such invoice
(i) deliver written notice to Orbitz explaining in detail why Airline believes
that an item or items are not correct and (ii) pay to Orbitz all amounts on the
invoice that are not the subject of a good faith dispute by Airline. If Airline
disputes any


                       CONFIDENTIAL               Page 8

<Page>

invoice rendered or amount paid, the parties will use all reasonable efforts to
resolve such dispute expeditiously. If Airline so notifies Orbitz of a disputed
amount, the time for paying the disputed portion of the invoice shall be
extended by a period of time equal to the time between Orbitz's receipt of such
notice from Airline and the resolution of such dispute; provided however that in
no event will Airline pay less than the monthly minimum transaction fee set
forth in Exhibit D.

         6.5      TAXES. The Pre-Launch Development Fees, the Hosting and
Support Fees, and the Reimbursable Expenses are exclusive of all sales, services
or other taxes that Orbitz may be legally obligated to charge Airline for
performing the Services, and Airline will promptly pay, or reimburse Orbitz for
the payment of, any and all such taxes that may be due or payable. For the
avoidance of doubt, Airline shall pay all sales and use taxes that are lawfully
imposed by any governmental authority in the United States and are based on or
measured by any payments of Airline pursuant to this Agreement, and for which no
exemption is available. Orbitz shall pay all taxes that are: (i) on, based on,
or measured by, gross or net income or gross or net receipts (including any
capital gains taxes or minimum taxes) of Orbitz, or taxes which are capital,
doing business, excess profits, net worth, or franchise taxes of Orbitz; (ii)
caused by or arising out of the willful misconduct or negligence of Orbitz; or
(iii) any interest, additions to tax, or penalties associated with the taxes set
forth in (i) or (ii) above.

No sales tax shall be collected by Orbitz if: (i) a specific exemption applies
to (a) the Products or Services purchased hereunder, or (b) any transaction
occurring pursuant to this Agreement, (ii) Airline has provided Orbitz with
written confirmation that Airline is authorized to make tax payments directly to
the applicable taxing authorities, or (iii) Orbitz is obligated to pay the taxes
as set forth herein. Orbitz shall promptly, upon receipt from any tax authority
of any levy, notice, assessment, or withholding of any tax for which Airline may
be obligated, notify Airline in writing directed to the following address:
Senior Tax Counsel, Northwest Airlines, Inc., Dept. A4450, 5101 Northwest Drive,
St. Paul, MN 55111-3034.

If under the applicable law of the taxing jurisdiction Airline is allowed
directly to contest such tax in its own name, then Airline shall be entitled, at
its own expense and in its own name, to contest the imposition, validity,
applicability or amount of such tax and, to the extent permitted by law,
withhold payment during pendency of such contest. If Airline is not permitted by
law to contest such tax in its own name, upon Airline's request, Orbitz shall in
good faith and using best efforts, at Airline's expense, contest the imposition,
validity, applicability or amount of such tax. Orbitz shall in good faith and
using best efforts: (i) supply Airline with such information and documents
reasonably requested by Airline as are necessary or advisable for Airline to (a)
recover or seek a refund of any sales or use tax paid by Airline as a result of
this Agreement; or (b) control or participate in any proceeding to the extent
permitted herein, and (ii) reasonably assist Airline with evidentiary and
procedural development of any such proceeding or contest.

Upon Airline's request, Orbitz shall delineate the fees among the Component
Portions of the Service contracted for in this Agreement. The term "Component
Portions" for purposes of this paragraph shall include, but is not limited to:
(i) maintenance, including upgrades and enhancements, (ii) installation, (iii)
support, and (iv) training and related manuals.

         6.6      MOST FAVORED CUSTOMER. During the Term, the financial terms of
this Agreement, including the fees set forth in Exhibit D, will be at least as
favorable or more favorable than the financial terms of any other current or
prospective Orbitz customer that engages Orbitz for a project that is
substantially similar to the engagement contemplated herein. The determination
of what is and is not "substantially similar" will be based on relevant factors
such as scope of project, volume of transactions, amount of integration and
custom development work required, and pricing model. Any change in financial
terms pursuant to this clause will only be applied on a prospective basis,
effective as of the effective date of such other customer's agreement with
Orbitz, whether such agreement is effective before or after the Effective Date.


                       CONFIDENTIAL               Page 9

         6.7      REPORTING; AUDIT. Orbitz will create and maintain accurate
records with respect to its performance under this Agreement. Orbitz will
maintain such records during the Term and for seven (7) years following any
expiration or termination of this Agreement. Within five (5) days following the
end of each applicable month, Orbitz will provide Airline with written reports
of such information. Airline will have the right, upon not less than five (5)
days prior notice, to conduct an audit of the information included in such
monthly reports. If such an audit reveals that any of Orbitz's reports submitted
overstated amounts owed by Airline, then Orbitz shall pay to Airline, within
thirty (30) days following the conclusion of such audit, the amount of any such
overpayments.

         6.8      CALCULATION OF FARES. Orbitz will use Worldspan, or any other
system approved in writing by Airline, to calculate the total fares sold through
the Website.

7.       CHANGE REQUESTS

         7.1      CHANGE REQUEST. If either party wants to request a
modification, addition or replacement of the Orbitz Software (including, but not
limited to, the Core Software and the Airline-Specific Software) or the Hosting
and Support Services, that party's Relationship Manager will submit a completed
Change Request to the Relationship Manager of the other party. The Change
Request will adequately describe (a) the requested modification, (b) the
estimated resources required to implement the modification, (c) its impact on
the Schedule, (d) its impact, if any, resulting in an increase or decrease to
any license and development fees and/or the Hosting and Support Fees and (e) its
impact on the maintenance requirements of the Orbitz Software.

         7.2      CHANGE ACCEPTANCE. Upon receipt of a completed Change Request,
the recipient Relationship Manager will either (a) expressly accept the proposed
modification without qualification within five (5) days after its receipt or (b)
defer the request for discussion at the next scheduled or emergency status
meeting. The Relationship Managers will use reasonable commercial efforts to
resolve any deferred proposed modification expeditiously. No proposed Change
Request will be effective unless expressly accepted by the primary or alternate
Relationship Managers of both parties. If so accepted, the Change Request will
be executed by the Relationship Managers of both parties and will then
constitute a formal amendment of this Agreement.

8.       CONFIDENTIALITY

         8.1      NDA. The following provisions shall supplement the terms of
that certain Non-Disclosure Agreement that was attached to the Letter of Intent
between Airline and Orbitz executed on March 8, 2000 (the "NDA"), a copy of
which is attached as Exhibit G to this Agreement and incorporated by reference
herein. The NDA shall continue to be in full force and effect during the term of
this Agreement. "Confidential Information" shall have the meaning ascribed in
the NDA.

         8.2      PROTECTION OF CONFIDENTIAL INFORMATION. Each party agrees to
maintain strict confidentiality regarding the subject matter of this Agreement,
in accordance with the NDA. Each party will take such measures that are
necessary to protect against the disclosure or use of the Confidential
Information of the other party as it takes to protect its own proprietary or
confidential information (but in any case no less than reasonable measures).
Each party agrees that the other party will have no adequate remedy at law if
there is a breach or threatened breach of this Section 8 or the NDA and,
accordingly, that either party will be entitled (in addition to any legal or
equitable remedies available to such party) to injunctive or other equitable
relief to prevent or remedy such breach.


                       CONFIDENTIAL               Page 10

         8.3      RESTRICTIONS ON DISCLOSURE AND USE. Notwithstanding anything
contained in the NDA, Orbitz will not disclose any Confidential Information
provided to it by Airline, including the terms and conditions of this Agreement,
to any equity owners or principals of Orbitz that are employed by a Competitor
of Airline except to the extent required by the laws of the State of Delaware
and/or the Orbitz LLC Agreement. In the event such disclosure is required
pursuant to the laws of the State of Delaware, Orbitz will provide advance
notice to the Vice President of E-Commerce and Distribution at Airline and
provide Airline sufficient time to contest the need for such disclosure prior to
making such disclosure. In the event disclosure is required pursuant to the
Orbitz LLC Agreement, Orbitz will provide advance notice to, and obtain written
approval of such disclosure from, the Vice President of E-Commerce and
Distribution at Airline, which approval will not be unreasonably withheld.

9.       PROPRIETARY RIGHTS

         9.1      OWNERSHIP. As between Airline and Orbitz, and to the extent of
Orbitz's prior ownership rights, Airline acknowledges that Orbitz will own all
patents (including any business process patents), rights to file for patents,
inventions, copyrights, trademarks, trade secrets and all other right, title and
interest (including any renewals or extensions) in or to the Orbitz Software,
except as otherwise provided in this Section 9, including the Airline-Specific
Software developed by Orbitz or its employees or Subcontractors during the
performance of this Agreement and any derivative works thereof. Airline hereby
assigns and agrees to assign, and will cause its subcontractors to assign, to
Orbitz all rights that Airline may have or acquire in or to such works for no
additional consideration. No other person will acquire or retain any rights in
or to such works, unless Orbitz otherwise agrees on a case-by-case basis. At
Orbitz's request and expense, Airline, for no additional consideration, will
cause the execution of the instruments that may be appropriate to give full
legal effect to this Section.

         For the avoidance of doubt, as between Airline and Orbitz, and to the
extent of Airline's prior ownership rights, Orbitz acknowledges that Airline
will own all patents related to its internally developed business processes, and
the rights to file for such patents, inventions, copyrights, trademarks, and
trade secrets.

         9.2      LICENSE TO AIRLINE.

                  A. Upon Airline's acceptance of any Orbitz Software, Orbitz
                     grants Airline the limited, non-exclusive,
                     non-transferable, worldwide right, effective during the
                     Term, to access and use (and permit its customers to access
                     and use) the Orbitz Software in conjunction with an
                     unlimited number of (i) Websites or (ii) other Airline
                     applications, on the terms and conditions set forth in this
                     Agreement. Airline will have no obligation to pay any
                     license fees or royalties to Orbitz's licensors, if any,
                     with respect to the license of the Orbitz Software granted
                     herein. Airline acknowledges and agrees that any access and
                     use by its customers will be subject to the terms and
                     conditions posted to the Website, which will include
                     reasonable protections for Orbitz at least as protective as
                     the terms and conditions that Airline posts to protect its
                     own rights, limit its liability, and disclaim forms of
                     damages. Such terms and conditions to be approved by
                     Airline, with such approval not to be unreasonably
                     withheld. Airline will not display or use the Orbitz
                     Software as part of any third party site or service.
                     Notwithstanding the foregoing, the Website may be branded,
                     as determined by Airline, with Airline branding, and, at
                     Airline's election, branding of KLM Royal Dutch Airlines,
                     Continental Airlines, other Affiliate Airlines and/or a
                     global alliance brand such as "Wings".

                  B. Upon Airline's acceptance of any Orbitz Software, Orbitz
                     grants Airline a limited, non-exclusive, non-transferable,
                     worldwide right, effective during the Term, to use the
                     object/executable code to the Orbitz Software, and all
                     Documentation related thereto to modify the
                     Airline-Specific Software pursuant to Section 9.3.

         9.3      AIRLINE MODIFICATIONS. Airline shall have the right to modify
the Airline-Specific Software and to create external programs that may interface
with the Orbitz Software; provided that such interfaces may not be used to
create competitive travel agency web sites. Notwithstanding the foregoing,
Airline may use the external programs to provide travel agency access to the
Website. Orbitz will have no responsibility under this Agreement to support or
maintain any such external programs. Orbitz will provide to Airline all
Documentation to the Orbitz Software that will permit Airline to create such
interfaces.


                       CONFIDENTIAL               Page 12

<Page>

         Any inventions, improvements, developments, processes or methods,
computer programs, or enhancements that are made, invented, or developed by
Airline to the Airline-Specific Software or any customizations to the Orbitz
Software that are developed by Orbitz for Airline and expressly agreed by the
parties to be custom for Airline under a separate Change Request pursuant to
Section 7, shall be deemed to be "Custom Material". Title and full ownership of
any Custom Material, whether patentable or otherwise, shall vest in Airline.
Orbitz shall not assert or establish a claim for any statutory or common law
patent or copyright or any other possessory or proprietary right on any Custom
Material. If requested by Airline and without any further compensation, Orbitz
shall execute appropriate documents of assignment to effectuate the purposes of
this Section 9.3.

         Orbitz shall fully cooperate with Airline enforcing any patents,
copyrights, or other possessory or proprietary rights, provided that in the
event any assistance by Orbitz is requested and rendered pursuant to this
Section 9.3, Airline shall reimburse Orbitz for out-of-pocket expenses incurred
by Orbitz in rendering such assistance.


         9.4      OPTIONAL LICENSE. At the expiration or termination of this
Agreement, Airline will have the option to purchase from Orbitz, and Orbitz
agrees to grant to Airline, a perpetual, non-exclusive, paid-up license to the
source and object code for the Orbitz Software (including the related
Documentation) for a [***] fee [***]. In the event that this Agreement
terminates at least two years from the Launch Date, the fee for a
non-transferable, perpetual, paid-up license to the Airline-Specific Software
source and object code, and related Documentation, will be waived. In the event
that the parties are unable to agree on the fee for the Core Software after a
period of thirty (30) days after expiration or termination of this Agreement,
the parties will jointly apply to and pay for an independent third party through
the Information Technology Association of America to determine such fee and the
determination of such third party will be final and binding on the parties,
provided, however, that Airline will be under no obligation to effectuate the
acquisition. After such purchase, Airline will have the right to host, modify,
maintain, support and use the Orbitz Software, pursuant to the terms of this
Agreement in conjunction with (i) the operation of Websites or (ii) any other
Airline applications. Unless otherwise agreed by the parties, Airline will not
use the Orbitz Software as part of any third party site or service.

         9.5      LICENSE TO ORBITZ. Effective during the Term, Airline hereby
grants Orbitz the limited, non-exclusive, non-transferable, royalty-free,
world-wide right to (a) use the Airline Information solely to perform its
obligations under this Agreement; (b) use aggregated customer data derived from
Website bookings for internal site management purposes; and (c) permit
Subcontractors to use aggregate use data (that is not identified or identifiable
with any individual customer or user) derived from the Airline Information in
connection with user and performance statistics, so long as such aggregated data
does not make reference to the travel industry.

10.      ESCROW

         10.1     ESCROWED MATERIALS. No later than sixty (60) days after the
Launch Date, and within thirty (30) days after release of each Update, Orbitz
will deliver to DSI, as escrow agent, the following: (a) a copy of the current,
fully commented version of the source code of the latest release of the Orbitz
Software that Orbitz owns, (b) the available Documentation related thereto, and
(c) reproducible binary masters of the latest release of the Orbitz Software
(collectively, "Escrowed Material"). A copy of the

respect to the omitted portions.


                       CONFIDENTIAL               Page 13

<Page>

Escrow Agreement between Orbitz and DSI related to the Escrowed Materials will
be attached hereto as Exhibit H upon execution.

         10.2     MAINTENANCE. Orbitz will replace the source code of the Orbitz
Software in the event of a media defect. The nature and completeness of the
Escrowed Materials will be subject to verification by a representative of
Airline only at the facilities of the escrow agent in the presence of a
representative of Orbitz. Except as provided in the Escrow Agreement and in
Section 10.4 below, Airline may not make any copies, in whole or in part, of the
Escrowed Material, and all such material will be considered to be Confidential
Information regardless of whether they have been marked "confidential". All
expenses associated with establishing and maintaining the Escrowed Materials
will be shared equally between Airline and Orbitz.

         10.3     RELEASE CONDITION. If Orbitz (a) generally discontinues the
operation, hosting or maintenance of the Orbitz Software, or (b) is insolvent,
files a petition in bankruptcy or has such a petition filed against it (and
fails to lift any stay imposed thereby within sixty (60) days after such stay
becomes effective), has a receiver appointed with respect to all or
substantially all of its assets, makes an assignment for the benefit of
creditors, or ceases to do business in the ordinary course, or (c) is in
material breach of this Agreement, then Airline may demand the release of the
Escrowed Material by simultaneously sending the escrow agent, with a copy to
Orbitz, a written demand for the Escrowed Material by facsimile and overnight
courier. In such circumstances, release of the Escrowed Material will be
governed by Article 4 of the Escrow Agreement set forth in Exhibit H hereto.

         10.4     RIGHTS. In the event the Escrowed Material is released to
Airline, Orbitz grants to Airline a fully paid up license to use and modify the
Escrowed Material solely to maintain and support the Orbitz Software in
accordance with the terms of this Agreement and for no other purpose. Airline
will maintain the Escrowed Material on a secure system with access limited to
only those persons necessary to maintain and support the Orbitz Software.
Airline may make only such copies of the Escrowed Material as are reasonably
required for archival and disaster recovery purposes, and Airline will keep any
such copies under lock and key.

11.      WARRANTIES AND DISCLAIMERS

         11.1     GENERAL WARRANTY. Each party represents and warrants that (a)
it has the full corporate authority to execute this Agreement and perform its

any third party.

         11.2     SPECIFIC WARRANTIES. Orbitz represents and warrants that it

a good and workmanlike manner, Orbitz will re-perform the defective Pre-Launch
Development Services. In the event that Orbitz fails to meet or exceed the
service levels set forth in the Service Level Agreement, Airline will be
entitled to the applicable service level credits and/or the right to termination
set forth in the Service Level Agreement. This section and the applicable
section in the Service Level Agreement set forth Airline's exclusive remedies
and Orbitz's sole liabilities in the event of any breach of warranty with
respect to the quality of the Services.

         11.3     LIMITATION. The warranties and remedies specified in this
Section will not apply to the extent the Services are defective due to causes
beyond Orbitz's reasonable control, such as (a) natural disasters, including
without limitation fire, smoke, water, earthquakes or lightning, (b) electrical
power fluctuations or failures, (c) neglect or misuse by Airline, (d) a

UNINTERRUPTED USE, TIMELINESS, SEQUENCE, COMPLETENESS, MERCHANTABILITY, FITNESS
FOR PARTICULAR PURPOSE OR NON-INFRINGEMENT AND ANY IMPLIED WARRANTIES ARISING
FROM TRADE USAGE, COURSE OF DEALING OR COURSE OF PERFORMANCE) ARE HEREBY
OVERRIDDEN, EXCLUDED AND DISCLAIMED.

12.      INDEMNITY

         12.1     GENERAL THIRD-PARTY INDEMNITY.

                  (a)      Orbitz will indemnify, defend and hold harmless
Airline, as well as Airline's subsidiaries and its Affiliates, and each of their
directors, officers, employees, assignees, agents and shareholders (hereinafter
collectively called the "Airline Indemnified Parties") from and against any and
all Claims, including any related Losses that the Airline Indemnified Parties
are required to pay any third party in any way relating to, arising out of or
resulting from: (i) any gross negligence or willful misconduct of any employee
or Subcontractor of Orbitz; (ii) breach of any warranty of Orbitz contained in
Section 11.1 of this Agreement; (iii) any actual or alleged infringement of any
patent, copyright, trademark, trade name, trade secret or other proprietary or
intellectual property right by any software or service provided pursuant to this
Agreement; or (iv) Orbitz's failure to comply with any and all applicable laws,
rules and regulations.

                  (b)      Airline will indemnify and hold harmless Orbitz, as
well as Orbitz's subsidiaries, licensees and Affiliates, and each of their
officers, shareholders, directors, employees and agents (collectively, the
"Orbitz Indemnified Parties") from and against any and all Losses in any way
relating to, arising out of or resulting from: (i) any gross negligence or
willful misconduct of any employee or subcontractor of Airline; (ii) breach of
any warranty of Airline contained in Section 11.1 of this Agreement; (iii) any
actual or alleged infringement of any copyright, trademark, trade name, trade
secret or other proprietary or intellectual property or privacy right by the
Airline Information; or (iv) Airline's failure to comply with any and all
applicable laws, rules and regulations related to the Website.

         12.2     INDEMNIFICATION PROCEDURES.

                  (a)      Promptly after any party entitled to indemnification
under this Section 12 ("Indemnitee") obtains knowledge of the potential
existence or commencement of a Claim, in respect of which Indemnitee is or may
be entitled to indemnification under this Agreement, such Indemnitee will
promptly notify the other party ("Indemnitor") of such Claim in writing;
provided, however, that any failure to give such notice will not waive any
rights of Indemnitee except to the extent that the rights of Indemnitor are
actually prejudiced thereby. Indemnitor will assume the defense and settlement
of such Claim with counsel reasonably satisfactory to Indemnitee at Indemnitor's
sole risk and expense; provided, however, that Indemnitee (i) will be permitted
to join in the defense and settlement of such Claim and to employ counsel at its
own expense; (ii) will reasonably cooperate with Indemnitor in the defense and
any settlement of such Claim; and (iii) will have the right to pay or settle
such Claim at any time in which event Indemnitee will be deemed to have waived
any right to indemnification therefor by Indemnitor. Indemnitor


                       CONFIDENTIAL               Page 15

<Page>

may settle any Claim without Indemnitee's written consent unless such settlement
(A) does not include a release of all covered claims pending against Indemnitee;
(B) contains an admission of liability or wrongdoing by Indemnitee; or (C)
imposes any obligations upon Indemnitee other than an obligation to stop using
any infringing items.

                  (b)      If Indemnitor fails to assume the defense of such
Claim or, having assumed the defense and settlement of such Claim, fails
reasonably to contest such Claim in good faith, Indemnitee, without waiving its
right to indemnification, may assume the defense and settlement of such Claim;
provided, however, that Indemnitor (i) may join in the defense and settlement of
such Claim and employ counsel at its own expense and (ii) will cooperate with
Indemnitee in the defense and settlement of such Claim. Indemnitee may settle
such Claim without Indemnitor's written consent unless such settlement (A) does
not include a release of all covered Claims pending against Indemnitor; (B)
contains an admission of liability or wrongdoing by Indemnitor; or (C) imposes
any obligations upon Indemnitor other than an obligation to stop using any
infringing items. Indemnitor will be liable to Indemnitee for all costs and
expenses incurred in connection with the defense and settlement of any Claim
pursuant to this Section 12.2(b).

                  (c)      Upon a determination of liability in respect of this
Section 12, Indemnitor will pay Indemnitee the amount so determined within
thirty (30) business days after the date of such determination. If there should
be a dispute as to the amount or manner of determination of any indemnity
obligation owed under this Agreement, Indemnitor will nevertheless pay when due
such portion, if any, of the obligation as will not be subject to dispute. Upon
the payment in full of any claim, either by setoff or otherwise, the party or
entity making payment will be subrogated to the rights of Indemnitee against any
person, firm, corporation or other entity with respect to the subject matter of
such claim.

         12.3     INTELLECTUAL PROPERTY REMEDIES. In the event of a Claim under
Section 12.1(a)(iii) above, and in addition to all other obligations of Orbitz
in this Section 12, Orbitz will either (a) provide Airline with reasonable
assurances acceptable to Airline that Airline will continue to have the right to
use the affected products or services or (b) Orbitz will, at its expense, either
(i) procure for Airline the right to continue use of such infringing products or
services, or any component thereof; or (ii) replace or modify the same with
non-infringing products or services satisfactory to Airline, provided that
Orbitz will provide Airline with a comparable temporary replacement product or
reimburse Airline for the reasonable costs incurred by Airline in obtaining an
alternative product in the event Airline cannot use the affected product. If
Orbitz cannot accomplish any of the foregoing within a reasonable time and at
commercially reasonable rates, then Orbitz will accept the return of the
infringing component of the products or services, along with any other

         (iii)    COMMERCIAL GENERAL LIABILITY - $5,000,000 Combined Single

15.      DISPUTE RESOLUTION

         Unless otherwise agreed by the parties, any claim, controversy or other
dispute between the parties relating to this Agreement will, before the filing
of any legal action, be submitted to two senior executives representing Airline

possible ways of resolving the dispute amicably. Any resolution upon which these
executives may agree in writing will be final and binding on the parties. If the
executives do not resolve the dispute within thirty (30) days after the initial
request for an executive meeting, the parties may pursue any other legal
remedies available.

16.      TERM AND TERMINATION

         16.1     TERM. This Agreement shall be in effect as of the Effective
Date and will have an initial term of thirty (30) months following the Launch
Date (the "Initial Term"). This Agreement shall automatically renew for up to
three (3) successive one-year renewal terms (each, a "Renewal Term") (the
Initial Term and any Renewal Terms are collectively referred to herein as the
"Term"), unless Airline


                       CONFIDENTIAL               Page 17

<Page>

notifies Orbitz of its intention not to renew this Agreement at least ninety
(90) days prior to the expiration of the Initial Term or the then-current
Renewal Term.

         16.2     TERMINATION FOR CAUSE. Either party may terminate this
Agreement for cause in the event that the other party materially breaches its
obligations under this Agreement and fails to cure such breach within ninety
(90) days after receiving written notice of such breach from the non-breaching
party. Notwithstanding the foregoing, Airline may terminate this Agreement upon
fifteen (15) days prior written notice without penalty in the event of a
Material Service Level Failure, as defined in Exhibit F attached hereto.

         16.3     TERMINATION PRIOR TO LAUNCH DATE. If at any time prior to the
Launch Date (a) Orbitz assigns this Agreement or any of its rights or
obligations hereunder to an unrelated company pursuant to a sale, merger or
other consolidation of Orbitz or any of its operating divisions or offices, or
(b) Orbitz is acquired by another entity or merges with another entity and
Orbitz is not the surviving entity in such merger, then Airline may immediately
terminate this Agreement without penalty or any other obligation hereunder
except to pay Orbitz the amounts due, pursuant to the fee schedule set forth in
Exhibit D(I), for Services performed prior to the actual termination date.

         16.4     EFFECT OF TERMINATION. If this Agreement terminates or
expires, except as a result of a material breach by Orbitz, Airline will
promptly pay Orbitz any undisputed amounts. In addition, if this Agreement
terminates or expires, except as a result of a material breach by Orbitz or as a
result of the Release Conditions set forth in Section 10.3, all rights Airline
may have in or to the Orbitz Software, including without limitation the Core
Software and the Airline-Specific Software, will immediately cease following the
Transition Period described in Section 16.5. The provisions of Sections 8, 9.1
9.3, 9.4, 11, 12, 13, 15, 16.5, 18, and 19, will survive the expiration or
termination of this Agreement. Further, in the event Airline elects to purchase
a license to the Orbitz Software in accordance with Section 9.4, then the
provisions of Sections 9.1, 9.3, 9.4, and 10 will also survive the expiration or
termination of this Agreement.

         16.5     POST-TERMINATION. In the event that Airline provides written
notice of termination of the Agreement in accordance with the terms of this
Agreement, Orbitz will use reasonable efforts to cooperate with Airline and
Airline's new vendor, if any, in the transfer of all appropriate customer
information, as necessary to facilitate the transition to the new vendor. Prior
to the actual termination date of the Agreement, Airline shall have the right to
request that Orbitz continue to provide maintenance and support services for
Airline's Website(s) after the termination date of the Agreement ("Extended
Maintenance and Support Services") for such period of time as Airline may
reasonably request, up to ninety (90) days (the "Stand By Period"). In the event
that Airline requests that Orbitz provide such Extended Maintenance and Support
Services, such services shall be provided pursuant to the terms of the Agreement
at no additional charge for the duration of the Stand By Period.

17.      PUBLICITY

         Neither party will issue a press release, advertisement or public
statement concerning the existence of this Agreement, its contents or the
transactions contemplated by it without the express written consent of the other
for each such event. Airline will provide a prominent notice on the Website that
the Website is powered by Orbitz and its designees. The parties will mutually
agree upon the location and content of such notice.

18.      LEGAL STATUS

parties. The parties expressly disclaim such relationship, agree that they are
acting solely as independent contractors hereunder and agree that the parties

further reimburse Airline upon demand for any costs incurred by Airline to pay

OVERVIEW

Northwest's current Internet Booking Products are designed for customers
residing in the United States and Canada. All functionality is geared towards
those countries. Prices are quoted in local currency and local (meaning US
point-of-sale or CA point-of-sale) credit cards must be entered into the system.
Our Asia/Pacific products are not included in this statement of work.

BUSINESS FRAMEWORK

The following airlines can be booked on the site: Northwest, KLM, Northwest
designated or KLM designated codeshares, and option to add other Northwest
partners at a later date.

The site will be built in [***] WORLDSPAN. Therefore, ORBITZ is responsible for
ensuring that the SIDs created for this product are set up with the appropriate
functionality and permissions.

1)   ORBITZ agrees to work with Northwest's CRS/GDS system, WORLDSPAN

2)   ORBITZ agrees to provide functionality for the following points-of-sale
     (POS) markets (with the exception of booking car/hotel, which will be in
     the US POS only):

     a.   United States

     b.   Canada

3)   ORBITZ agrees to work jointly with Northwest and WORLDSPAN to develop
     booking product.

4)   ORBITZ agrees to provide all hosting services (servers, communication
     lines, routes etc).

5)   ORBITZ agrees to deliver selected functionality contained in this Statement
     of Work and stage other items in a `phased' approach. Current levels of
     functionality will be replicated which will allow a website transition.

6)   ORBITZ agrees to host booking engine server and agrees to specific service
     levels documented in the contract and plan to handle increased volumes.

7)   ORBITZ agrees to provide links to NWA's small corporate web product and

1)   ORBITZ wilt support one pseudo city code per POS for the site. ORBITZ will
     be responsible for insuring that the SIDs are created. (To clarify - Orbitz

2)   ORBITZ agrees that the customer support at the booking product will be
     handled through E-Travel Experts, Northwest's Online Support Center.

3)   ORBITZ agrees to allow Northwest to complete the ticket fulfillment
     process.

     of this document.

     web page will inform the customer of the age group that qualifies for
     senior or child fares. The website will also inform the customer that
     children and senior's ages will be checked at the airport. All special
     programs/fares described in this section are [***], accessible through
     WORLDSPAN. NWA will provide ORBITZ with a "logic" table, which will be used
     to determine which passenger types to use for different scenarios. For
     example, [***]. ORBITZ will use this table in order to support companion
     fares. This table may be updated frequently as sales dictate. ORBITZ will
     develop a system to allow easy update to table.

11)  The site will be set up so that end-users select a POS during registration

3.       SYSTEM AVAILABILITY

     (a) Monthly System Availability shall be defined using the following
formula.

             [***]


     Where   AP = Availability Percentage
             MM = Total minutes in a given month
             EMU = Actual Excluded Minutes Unavailable (or the fraction thereof)
             MU = Total Minutes Unavailable (or the fraction thereof)

     (b) Monthly System Availability Commitment. Monthly System Availability
Commitment is defined as [***]% for each contract year.

     (c) Minutes Unavailable. Minutes Unavailable shall be calculated from

Software is unavailable or (ii) the time Orbitz is notified that the Orbitz
Software is not operating according to Specifications or (iii) the time that the

Specifications.

     (d) Excluded Minutes Unavailable. Minutes Unavailable shall not include
minutes in which the Orbitz Software is unavailable due to (i) Scheduled
Downtime, (ii) failure of software, hardware, middleware or systems which are
necessary for the delivery of the Orbitz Software but which are not provided and

party networks; outages attributable to the guaranteed time to repair software,
hardware, middleware or systems afforded to Orbitz's Subcontractors, Airline's
third party computerized reservation system provider's ("CRS") hardware,
middleware, software, or systems; availability of the World Wide Web; software
owned or licensed by Airline connected to Orbitz Software; or any Orbitz

adjust to best serve the needs of its network and customer base. Maintenance
windows are currently defined as Mondays and Saturdays, 1 a.m. - 3 a.m. local
data center time and 11 p.m. Saturdays to 5 a.m. Sundays Pacific Time. Scheduled
Downtime that violates the foregoing requirements will violate the Monthly
System Availability Commitment. The parties agree that there shall be no
Scheduled Downtime unless such Scheduled Downtime is mutually agreed to in
writing by the parties, with such consent not to be unreasonably withheld.

[***] months of response time data and the metric shall be set as a result of
looking at [***] standard deviations from the mean of this data.

         (c)      The "System Response Time Commitment" shall [***].

         (d)      System Response Time Credit. For each month that Orbitz fails
to achieve at least [***]% performance at such System Response Time Commitment,
Airline shall receive a credit of $[***] subject to the limitation set forth in
Section C(1) of this Exhibit.

         (e)      If the actual Ticket volume exceeds [***]% of the Expected
Ticket Volume for any calendar month, the value of the System Response Time
Commitment will be increased by [***] percent ([***]%) for each [***] percent

    1      Critical Impact.  The problem or defect in the Orbitz      Notification within [***]; commitment
           Software or degradation of Hosting Services cannot be      to identify and implement steps to fix
           reasonably circumvented, rendering the Orbitz Software     and to use commercially reasonable
           unusable, including, but not limited to the inability to   efforts to fix within [***].  Orbitz
           price or book a Ticket                                     shall provide Airline with hourly
                                                                      updates as to its progress until the

---------- ---------------------------------------------------------- -----------------------------------------
    2      High Impact.  As mutually agreed to by the parties for     Notification within [***]; commitment
           each reported problem:  An error or defect in the Orbitz   to identify and implement steps to fix
           Software has caused incorrect results; and/or System       and to use commercially reasonable
           Response Time is greater than 3 times the agreed upon      efforts to fix within [***].

    4      Low Impact or Request for Enhancement.  The parties        As mutually agreed.
           agree that the problem encountered requires new
           functionality or an enhancement to be added to the
           existing Orbitz Software.

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


         (h)      Resolution by Orbitz.

                  (i)      Orbitz will use its commercially reasonable efforts
                           to provide a Resolution to each problem, within the
                           specified time periods above. The Airline SPOC will
                           use reasonable efforts to assist the Orbitz SPOC to
                           resolve the problem if problem determination is
                           unclear and impacts the resolution time frames noted.

                  (ii)     Orbitz will use commercially reasonable efforts to
                           meet the resolution times (depending on the Severity
                           Level) set forth above with respect to acknowledging,
                           formulating an action plan and resolving such
                           problems by contacting the Airline SPOC through
                           e-mail, telephone, fax or other reliable means of
                           communication. Orbitz will maintain a log of all
                           incoming problems for tracking purposes. Orbitz will
                           contact the Airline SPOC as soon as Orbitz discovers
                           that a problem cannot be resolved in the specified
                           time period.

                  (iii)    In the event that Orbitz reasonably determines that
                           the problem is not an error in or problem with the
                           Orbitz Software, Orbitz will promptly notify the
                           Airline SPOC with a detailed explanation. In the
                           event that Orbitz provides such notice, but the
                           Airline SPOC continues to request that Orbitz remedy
                           the problem, Orbitz may charge Airline for such
                           requests.


2.       NOTIFICATION BY ORBITZ

         (a)      Orbitz will notify Airline of (i) any known Orbitz Software or
hosted system errors; (ii) communications failures from Orbitz to the CRS host;
(iii) availability of the CRS Gateway, CRS Host, and CRS products called by the
Orbitz booking engine within the time frames set forth in Section B(1)(g) of
this Exhibit, depending on the Severity level of such problem. The parties agree
that Orbitz does not have responsibility for resolving the CRS specific
problems; however, Orbitz has the responsibility for communicating this
information to Airline as specified above.


3.       ESCALATION

         In the event that a Severity Level 1 or Severity Level 2 defect or
problem is not resolved within the response time listed in Section B.1.f. above,
such defect or problem will be reported to the applicable Project Managers and
Airline's Relationship Manager. If the Project Managers cannot agree on a
resolution and defect remains unresolved for 8 hours, the defect will be
reported to the Relationship Managers.

4.       REPORTING


                       CONFIDENTIAL               Page 33
<Page>

Orbitz will calculate System Availability Credits and System Response Time
Credits (whether or not such calculations result in a Credit due Airline) and
provide a report of the results to Airline (the "System Availability and
Performance Report") within 15 days after the end of each month. Airline and
Orbitz will work together to develop any reports with such reports to be
satisfactory to Airline, in its reasonable discretion.


C. TERMINATION OPTION AND LIMITATION OF REMEDIES


1.       LIMITATION OF REMEDIES



         In no event shall the total of System Availability Credits and System
Response Time Credits (individually and collectively, a "Credit") due Airline
during any month exceed the value of [***] percent ([***]%) of the Hosting and
Support Fee for such month. Further, in no event shall the total of Credits due
Airline during any Service Level Period exceed the value of [***] percent
([***]%) of the Expected Hosting and Support Fee during that Service Level
Period. Each such Credit owed Airline will be calculated within 15 days after
each month of the Service Level Period and applied to the next invoice or
scheduled payment or, if there is no subsequent installment due, Orbitz will
refund to Airline the amount of such Hosting Credits that have not been applied
to invoices.

                        MASTER PREFERRED ESCROW AGREEMENT


                      Master Number ______________________

This agreement ("Agreement") is effective ________, 20__ among DSI Technology
Escrow Services, Inc. ("DSI"), Orbitz LLC ("Depositor"), and any additional
party signing the Acceptance Form attached to this Agreement ("Preferred
Beneficiary"), who collectively may be referred to in this Agreement as the
parties ("parties").

A.       Depositor and Preferred Beneficiary have entered or will enter into an
agreement regarding certain proprietary technology of Depositor (referred to in
this Agreement as "the License Agreement").

B.       Depositor desires to avoid disclosure of its proprietary technology
except under certain limited circumstances.

C.       The availability of the proprietary technology of Depositor is critical
to Preferred Beneficiary in the conduct of its business and, therefore,
Preferred Beneficiary needs access to the proprietary technology under certain
limited circumstances.

D.       Depositor and Preferred Beneficiary desire to establish an escrow with
DSI to provide for the retention, administration and controlled access of
certain proprietary technology materials of Depositor.

E.       The parties desire this Agreement to be supplementary to the License
Agreement pursuant to 11 United States [Bankruptcy] Code, Section 365(n).

ARTICLE 1  --  DEPOSITS

1.1      OBLIGATION TO MAKE DEPOSIT. Upon the signing of this Agreement by the
parties, including the signing of the Acceptance Form, Depositor shall deliver
to DSI the proprietary technology and other materials ("Deposit Materials")
required to be deposited by the License Agreement or, if the License Agreement
does not identify the materials to be deposited with DSI, then such materials
will be identified on Exhibit A. If Exhibit A is applicable, it is to be
prepared and signed by Depositor and Preferred Beneficiary. DSI shall have no
obligation with respect to the preparation, signing or delivery of Exhibit A.

1.2      IDENTIFICATION OF TANGIBLE MEDIA. Prior to the delivery of the Deposit
Materials to DSI, Depositor shall conspicuously label for identification each
document, magnetic tape, disk, or other tangible media upon which the Deposit
Materials are written or stored. Additionally, Depositor shall complete Exhibit
B to this Agreement by listing each such tangible media by the item label
description, the type of media and the quantity. Exhibit B shall be signed by
Depositor and delivered to DSI with the Deposit Materials. Unless and until
Depositor makes the initial deposit with DSI, DSI shall have no obligation with
respect to this Agreement, except the obligation to notify the parties regarding
the status of the account as required in Section 2.2 below.

1.3      DEPOSIT INSPECTION. When DSI receives the Deposit Materials and the
Exhibit B, DSI will conduct a deposit inspection by visually matching the
labeling of the tangible media containing the Deposit Materials to the item
descriptions and quantity listed on the Exhibit B. In addition to the deposit
inspection,


                       CONFIDENTIAL               Page 36

<Page>

Preferred Beneficiary may elect to cause a verification of the Deposit Materials
in accordance with Section 1.6 below.

1.4      ACCEPTANCE OF DEPOSIT. At completion of the deposit inspection, if DSI
determines that the labeling of the tangible media matches the item descriptions
and quantity on Exhibit B, DSI will date and sign Exhibit B and mail a copy
thereof to Depositor and Preferred Beneficiary. If DSI determines that the
labeling does not match the item descriptions or quantity on Exhibit B, DSI will
(a) note the discrepancies in writing on Exhibit B; (b) date and sign Exhibit B
with the exceptions noted; and (c) mail a copy of Exhibit B to Depositor and
Preferred Beneficiary. DSI's acceptance of the deposit occurs upon the signing
of Exhibit B by DSI. Delivery of the signed Exhibit B to Preferred Beneficiary
is Preferred Beneficiary's notice that the Deposit Materials have been received
and accepted by DSI.

1.5      DEPOSITOR'S REPRESENTATIONS. Depositor represents as follows:

a.       Depositor lawfully possesses all of the Deposit Materials deposited
with DSI;

b.       With respect to all of the Deposit Materials, Depositor has the right
and authority to grant to DSI and Preferred Beneficiary the rights as provided
in this Agreement;

c.       The Deposit Materials are not subject to any lien or other encumbrance;

d.       The Deposit Materials consist of the proprietary technology and other
materials identified either in the License Agreement or Exhibit A, as the case
may be; and

e.       The Deposit Materials are readable and useable in their current form
or, if any portion of the Deposit Materials is encrypted, the decryption tools
and decryption keys have also been deposited.

1.6      VERIFICATION. A verification determines, in different levels of detail,
the accuracy, completeness, sufficiency and quality of the Deposit Materials.
Preferred Beneficiary shall have the right to cause a verification of any
Deposit Materials, at Preferred Beneficiary's expense. Preferred Beneficiary
shall notify Depositor and DSI of Preferred Beneficiary's request for
verification. Depositor shall have the right to be present at the verification.
If a verification is elected after the Deposit Materials have been delivered to
DSI, then only DSI, or at DSI's election an independent person or company
selected and supervised by DSI, may perform the verification.

1.7      DEPOSIT UPDATES. Unless otherwise provided by the License Agreement,
Depositor shall update the Deposit Materials within sixty (60) days of each
release of a new version of the product which is subject to the License
Agreement. Such updates will be added to the existing deposit. All deposit
updates shall be listed on a new Exhibit B and the new Exhibit B shall be signed
by Depositor. Each Exhibit B will be held and maintained separately within the
escrow account. An independent record will be created which will document the
activity for each Exhibit B. The processing of all deposit updates shall be in
accordance with Sections 1.2 through 1.6 above. All references in this Agreement
to the Deposit Materials shall include the initial Deposit Materials and any
updates.

1.8      REMOVAL OF DEPOSIT MATERIALS. The Deposit Materials may be removed
and/or exchanged only on written instructions signed by Depositor and Preferred
Beneficiary, or as otherwise provided in this Agreement.

ARTICLE 2  -- CONFIDENTIALITY AND RECORD KEEPING


                       CONFIDENTIAL               Page 37

<Page>

2.1      CONFIDENTIALITY. DSI shall maintain the Deposit Materials in a secure,
environmentally safe, locked facility which is accessible only to authorized
representatives of DSI. DSI shall have the obligation to reasonably protect the
confidentiality of the Deposit Materials. Except as provided in this Agreement,
DSI shall not disclose, transfer, make available, or use the Deposit Materials.
DSI shall not disclose the content of this Agreement to any third party. If DSI
receives a subpoena or any other order from a court or other judicial tribunal
pertaining to the disclosure or release of the Deposit Materials, DSI will
immediately notify the parties to this Agreement unless prohibited by law. It
shall be the responsibility of Depositor and/or Preferred Beneficiary to
challenge any such order; provided, however, that DSI does not waive its rights
to present its position with respect to any such order. DSI will not be required
to disobey any order from a court or other judicial tribunal. (See Section 7.5
below for notices of requested orders.)

2.2      STATUS REPORTS. DSI will issue to Depositor and Preferred Beneficiary a
report profiling the account history at least semi-annually. DSI may provide
copies of the account history pertaining to this Agreement upon the request of
any party to this Agreement.

2.3      AUDIT RIGHTS. During the term of this Agreement, Depositor and
Preferred Beneficiary shall each have the right to inspect the written records
of DSI pertaining to this Agreement. Any inspection shall be held during normal
business hours and following reasonable prior notice.

ARTICLE 3  --  GRANT OF RIGHTS TO DSI

3.1      TITLE TO MEDIA. Depositor hereby transfers to DSI the title to the
media upon which the proprietary technology and materials are written or stored.
However, this transfer does not include the ownership of the proprietary
technology and materials contained on the media such as any copyright, trade
secret, patent or other intellectual property rights.

3.2      RIGHT TO MAKE COPIES. DSI shall have the right to make copies of the
Deposit Materials as reasonably necessary to perform this Agreement. DSI shall
copy all copyright, nondisclosure, and other proprietary notices and titles
contained on the Deposit Materials onto any copies made by DSI. With all Deposit
Materials submitted to DSI, Depositor shall provide any and all instructions as
may be necessary to duplicate the Deposit Materials including but not limited to
the hardware and/or software needed.

3.3      RIGHT TO TRANSFER UPON RELEASE. Depositor hereby grants to DSI the
right to transfer Deposit Materials to Preferred Beneficiary upon any release of
the Deposit Materials for use by Preferred Beneficiary in accordance with
Section 4.5. Except upon such a release or as otherwise provided in this
Agreement, DSI shall not transfer the Deposit Materials.

ARTICLE 4  -- RELEASE OF DEPOSIT

4.1      RELEASE CONDITIONS. As used in this Agreement, "Release Condition"
shall mean those conditions set forth in Section 10.3 of the License Agreement.

4.2      FILING FOR RELEASE. If Preferred Beneficiary believes in good faith
that a Release Condition has occurred, Preferred Beneficiary may provide to DSI
written notice of the occurrence of the Release Condition and a request for the
release of the Deposit Materials. Upon receipt of such notice, DSI shall provide
a copy of the notice to Depositor by facsimile and overnight courier.

4.3      CONTRARY INSTRUCTIONS. From the date DSI transmits the notice
requesting release of the Deposit Materials, Depositor shall have two (2)
business days to deliver to DSI contrary instructions ("Contrary Instructions").
Contrary Instructions shall mean the written representation by Depositor that a
Release Condition has not occurred or has been cured. Upon receipt of Contrary
Instructions, DSI shall send a


                       CONFIDENTIAL               Page 38

<Page>

copy to Preferred Beneficiary by facsimile and overnight courier. After
transmitting Contrary Instructions to DSI, Depositor shall have ten (10)
calendar days to provide Preferred Beneficiary with material information which
establishes that none of the Release Conditions have occurred ("Material
Information"). A copy of the Material Information shall be simultaneously sent
to DSI. If Depositor provides such Material Information to Preferred
Beneficiary, DSI shall notify both Depositor and Preferred Beneficiary that
there is a dispute to be resolved pursuant to Section 7.3 of this Agreement.
Subject to Section 5.2 of this Agreement, DSI will continue to store the Deposit
Materials without release pending (a) joint instructions from Depositor and
Preferred Beneficiary; (b) dispute resolution pursuant to Section 7.3; or (c)
order of a court.

4.4      RELEASE OF DEPOSIT. If DSI does not receive Contrary Instructions from
the Depositor or if Depositor does not provide Material Information to Preferred
Beneficiary, DSI is authorized to release the Deposit Materials to the Preferred
Beneficiary or, if more than one beneficiary is registered to the deposit, to
release a copy of the Deposit Materials to the Preferred Beneficiary. However,
DSI is entitled to receive any fees due DSI before making the release. Any
copying expense in excess of $300 will be chargeable to Preferred Beneficiary.
Upon any such release, the escrow arrangement will terminate as it relates to
the Depositor and Preferred Beneficiary involved in the release.

4.5      RIGHT TO USE FOLLOWING RELEASE. Unless otherwise provided in the
License Agreement, upon release of the Deposit Materials in accordance with this
Article 4, Preferred Beneficiary shall have the right to use the Deposit
Materials for the sole purpose of continuing the benefits afforded to Preferred
Beneficiary by the License Agreement. Preferred Beneficiary shall be obligated
to maintain the confidentiality of the released Deposit Materials.

ARTICLE 5  --  TERM AND TERMINATION

5.1      TERM OF AGREEMENT. The initial term of this Agreement is for a period
of one year. Thereafter, this Agreement shall automatically renew from
year-to-year unless (a) Depositor and Preferred Beneficiary jointly instruct DSI
in writing that the Agreement is terminated; or (b) DSI instructs Depositor and
Preferred Beneficiary in writing that the Agreement is terminated for nonpayment
in accordance with Section 5.2 or by resignation in accordance with Section 5.3.
If the Acceptance Form has been signed at a date later than this Agreement, the
initial term of the Acceptance Form will be for one year with subsequent terms
to be adjusted to match the anniversary date of this Agreement. If the Deposit
Materials are subject to another escrow agreement with DSI, DSI reserves the
right, after the initial one year term, to adjust the anniversary date of this
Agreement to match the then prevailing anniversary date of such other escrow
arrangements.

5.2      TERMINATION FOR NONPAYMENT. In the event of the nonpayment of fees owed
to DSI, DSI shall provide written notice of delinquency to the parties to this
Agreement affected by such delinquency. Any such party shall have the right to
make the payment to DSI to cure the default. If the past due payment is not
received in full by DSI within one month of the date of such notice, then at any
time thereafter DSI shall have the right to terminate this Agreement to the
extent it relates to the delinquent party by sending written notice of
termination to such affected parties. DSI shall have no obligation to take any
action under this Agreement so long as any payment due to DSI remains unpaid.

5.3      TERMINATION BY RESIGNATION. DSI reserves the right to terminate this
Agreement, for any reason, by providing Depositor and Preferred Beneficiary with
60-days' written notice of its intent to terminate this Agreement. Within the
60-day period, the Depositor and Preferred Beneficiary may provide DSI with
joint written instructions authorizing DSI to forward the Deposit Materials to
another escrow company and/or agent or other designated recipient. If DSI does
not receive said joint written instructions within 60 days of


                       CONFIDENTIAL               Page 39

<Page>

the date of DSI's written termination notice, then DSI shall destroy, return or
otherwise deliver the Deposit Materials in accordance with Section 5.4.

5.4      DISPOSITION OF DEPOSIT MATERIALS UPON TERMINATION. Subject to the
foregoing termination provisions, and upon termination of this Agreement, DSI
shall destroy, return, or otherwise deliver the Deposit Materials in accordance
with instructions. If there are no instructions, DSI may, at its sole
discretion, destroy the Deposit Materials or return them to Depositor. DSI shall
have no obligation to destroy or return the Deposit Materials if the Deposit
Materials are subject to another escrow agreement with DSI or have been released
to the Preferred Beneficiary in accordance with Section 4.4.

5.5      SURVIVAL OF TERMS FOLLOWING TERMINATION. Upon termination of this
Agreement, the following provisions of this Agreement shall survive:

a.       Depositor's Representations (Section 1.5);

b.       The obligations of confidentiality with respect to the Deposit
Materials;

c.       The rights granted in the sections entitled Right to Transfer Upon
Release (Section 3.3) and Right to Use Following Release (Section 4.5), if a
release of the Deposit Materials has occurred prior to termination;

d.       The obligation to pay DSI any fees and expenses due;

e.       The provisions of Article 7; and

f.       Any provisions in this Agreement which specifically state they survive
the termination of this Agreement.

ARTICLE 6  --  DSI'S FEES

6.1      FEE SCHEDULE. DSI is entitled to be paid its standard fees and expenses
applicable to the services provided. Unless otherwise stated in this Agreement
or agreed in a writing signed by DSI, Depositor will pay DSI's fees. DSI shall
notify the party responsible for payment of DSI's fees at least sixty (60) days
prior to any increase in fees. For any service not listed on DSI's standard fee
schedule, DSI will provide a quote prior to rendering the service, if requested.

6.2      PAYMENT TERMS. DSI shall not be required to perform any service unless
the payment for such service and any outstanding balances owed to DSI are paid
in full. Fees are due upon receipt of a signed contract or receipt of the
Deposit Materials whichever is earliest. If invoiced fees are not paid, DSI may
terminate this Agreement in accordance with Section 5.2.

ARTICLE 7  --  LIABILITY AND DISPUTES

7.1      RIGHT TO RELY ON INSTRUCTIONS. DSI may act in reliance upon any
instruction, instrument, or signature reasonably believed by DSI to be genuine.
DSI may assume that any employee of a party to this Agreement who gives any
written notice, request, or instruction has the authority to do so. DSI shall
not be required to inquire into the truth or evaluate the merit of any statement
or representation contained in any notice or document. DSI shall not be
responsible for failure to act as a result of causes beyond the reasonable
control of DSI.


                       CONFIDENTIAL               Page 40

<Page>

7.2      INDEMNIFICATION. Depositor and Preferred Beneficiary each agree to
indemnify, defend and hold harmless DSI from any and all claims, actions,
damages, arbitration fees and expenses, costs, attorney's fees and other
liabilities ("Liabilities") incurred by DSI relating in any way to this escrow
arrangement unless such Liabilities were caused solely by the negligence or
willful misconduct of DSI.

7.3      DISPUTE RESOLUTION. Any dispute relating to or arising from this
Agreement shall be resolved by arbitration using a panel of three (3)
arbitrators under the Commercial Rules of the American Arbitration Association.
Three arbitrators shall be selected. The Depositor and Preferred Beneficiary
shall each select one arbitrator and the two chosen arbitrators shall select the
third arbitrator, or failing agreement on the selection of the third arbitrator,
the American Arbitration Association shall select the third arbitrator. However,
if DSI is a party to the arbitration, DSI shall select the third arbitrator.
Unless otherwise agreed by Depositor and Preferred Beneficiary, arbitration will
take place in Chicago, Illinois, USA. Any court having jurisdiction over the
matter may enter judgment on the award of the arbitrators. Service of a petition
to confirm the arbitration award may be made by First Class mail or by
commercial express mail, to the attorney for the party or, if unrepresented, to
the party at the last known business address.

7.4      CONTROLLING LAW. This Agreement is to be governed and construed in
accordance with the laws of New York, without regard to its conflict of law
provisions.

7.5      NOTICE OF REQUESTED ORDER. If any party intends to obtain an order from
the arbitrator or any court of competent jurisdiction which may direct DSI to
take, or refrain from taking any action, that party shall:

a.       Give DSI at least two business days' prior notice of the hearing;

b.       Include in any such order that, as a precondition to DSI's obligation,
DSI be paid in full for any past due fees and be paid for the reasonable value
of the services to be rendered pursuant to such order; and

c.       Ensure that DSI not be required to deliver the original (as opposed to
a copy) of the Deposit Materials if DSI may need to retain the original in its
possession to fulfill any of its other escrow duties.

ARTICLE 8  --  GENERAL PROVISIONS

8.1      ENTIRE AGREEMENT. This Agreement, which includes the Acceptance Form
and Exhibits described herein, embodies the entire understanding among all of
the parties with respect to its subject matter and supersedes all previous
communications, representations or understandings, either oral or written. DSI
is not a party to the License Agreement between Depositor and Preferred
Beneficiary and has no knowledge of any of the terms or provisions of any such
License Agreement. DSI's only obligations to Depositor or Preferred Beneficiary
are as set forth in this Agreement. No amendment or modification of this
Agreement shall be valid or binding unless signed by all the parties hereto,

Preferred Beneficiary, Exhibit C need not be signed, and the Acceptance Form
need only be signed by the parties identified therein.

8.2      NOTICES. All notices, invoices, payments, deposits and other documents
and communications shall be given to the parties at the addresses specified in
the attached Exhibit C and Acceptance Form. It shall be the responsibility of

change of address. The parties shall have the right to rely on the last known
address of the other parties. Unless otherwise provided in this Agreement, all
documents and communications may be delivered by First Class mail.

8.3      SEVERABILITY. In the event any provision of this Agreement is found to
be invalid, voidable or unenforceable, the parties agree that unless it
materially affects the entire intent and purpose of this Agreement, such
invalidity, voidability or unenforceability shall affect neither the validity of
this Agreement nor the remaining provisions herein, and the provision in
question shall be deemed to be replaced with a valid and enforceable provision
most closely reflecting the intent and purpose of the original provision.

8.4      SUCCESSORS. This Agreement shall be binding upon and shall inure to the
benefit of the successors and assigns of the parties. However, DSI shall have no
obligation in performing this Agreement to recognize any successor or assign of
Depositor or Preferred Beneficiary unless DSI receives clear, authoritative and
conclusive written evidence of the change of parties.
