11.  Confidentiality.

     11.1  The Parties agree that during the term of this Agreement there may be
a need to exchange certain confidential or proprietary information
("Confidential Information"). Confidential Information shall be defined as the
terms of this Agreement and any confidential, trade secret, or other proprietary
information disclosed by one Party (the

                                        9

<PAGE>

"Disclosing Party") to the other Party (the "Receiving Party") under this
Agreement, provided that such information is marked or otherwise identified at
the time of disclosure as being confidential or proprietary information of the
Disclosing Party. The Parties agree to mark any Confidential Information
disclosed in tangible form with a suitable legend. Confidential Information
shall not include information that (i) is public knowledge at the time of
disclosure, (ii) was known by the Receiving Party before disclosure by the
Disclosing Party, or becomes public knowledge or otherwise known to the
Receiving Party after such disclosure, other than by breach of the
confidentiality obligations of this Agreement, or (iii) is independently
developed by the Receiving Party by persons without access to Confidential
Information of the Disclosing Party.

     11.2  For a period of three (3) years after the Receiving Party receives
any particular component of the Disclosing Party's Confidential Information,
the Receiving Party shall use its reasonable best efforts, but in no instance
less than reasonable care, to limit dissemination of the component of
Confidential Information to such of its employees and agents who have a strict
need to know in the performance of the Receiving Party's duties hereunder, and
not disclose the Confidential Information to any third party, except as may be
reasonably necessary to load, host or remove the Certified Applications on or
from a Distribution Server.

     11.3  The Receiving Party shall take appropriate action, by instruction,
agreement, or otherwise, with any persons permitted access to the Disclosing
Party's Confidential Information so as to assure that they will hold such items
in confidence. All Receiving Party personnel who receive or use the Confidential
Information of the Disclosing Party shall, before receipt or use of such
information, be informed of the Receiving Party's obligations under this
Agreement.

     11.4  The Receiving Party agrees to return to the Disclosing Party, upon
termination of this Agreement, the Disclosing Party's Confidential Information
and any and all copies and derivatives thereof, or certify the destruction of
same upon the request of the Disclosing Party.

     11.5  The Parties agree that any breach of the confidentiality obligations
of this Section 11 may result in irreparable harm to the Disclosing Party for
which damages would be an inadequate remedy and, therefore, in addition to its
rights and remedies otherwise available at law, the Disclosing Party shall be
entitled to seek equitable relief, including injunction, in the event of such
breach.

12.  Term and Termination.

     12.1  Term. The term of this Agreement shall begin on the Effective Date
and shall continue for a period of three (3) years ("Initial Term"), unless
earlier terminated as provided herein. The term of this Agreement shall
automatically renew for one or more additional one (1) year periods (each such
one-year period being referred to herein as a "Renewal Term") upon expiration of
the Initial Term or any Renewal Term, unless a notice of non-renewal is
communicated by one Party to the other at least ninety (90) calendar days prior
to the expiration of the Initial Term or a particular Renewal Term, as the case
may be. Neither Party shall be liable to the other for any termination of this
Agreement in accordance with its terms or for any refusal, to renew or to extend
its term.

     12.2  Termination for Cause. If either Party ("Defaulting Party") fails to
perform a material obligation of this Agreement, the other Party may notify the
Defaulting Party of its intent to terminate this Agreement for cause

                                       10

<PAGE>

by giving the Defaulting Party thirty (30) calendar days prior written notice.
If the Defaulting Party cures its non-performance within the thirty (30)
calendar day period, this Agreement shall remain in full force and effect;
otherwise this Agreement shall automatically terminate upon expiration of the
thirty (30) calendar day period, subject to Motorola's limited right to sell-off
as set forth in Section 13 below.

     12.3 Insolvency. All rights and licenses granted under or pursuant to this
Agreement by Licensor to Motorola are, and shall otherwise be deemed to be, for
purposes of Section 365(n) of the United States Bankruptcy Code (or any other
section(s) of the United States Bankruptcy Code in effect on the Effective Date
of this Agreement that addresses rights in executory contracts), 11 U.S.C.
Section 101 et seq. (the "Bankruptcy Code"), licenses of rights to "intellectual
property" as such term is defined under the Bankruptcy Code. The Parties agree
that Motorola, as a licensee of such rights and licenses, shall retain and may
fully exercise all of its rights and elections under the Bankruptcy code, and
that Motorola shall have the right to retain and enforce its rights under this
Agreement provided it abides by the terms of this Agreement.

     12.4 Rights and Duties Upon Termination. In the event of expiration or
termination of this Agreement: (i) Motorola shall promptly remove the Certified
Applications from all Distribution Servers and, subject to Motorola's limited
right to sell-off as set forth in Section 13 below, shall not license or
otherwise dispose of the Certified Applications to any third party after such
expiration or termination; and (ii) Licensor shall be responsible for continued
support of past licenses of the Certified Applications and sales of Certified
Applications during the Sell-Off Period specified in Section 13.

     12.5 Survival. Except as provided in this Section 12, there shall be no
further remedies or obligations from either Party upon termination of this
Agreement, except those obligations, rights and remedies set forth in Sections
1, 2.5-2.9, 4 (through completion of the below-defined Sell-Off Period only), 6,
7 (including the provisions of Exhibit C), 10, 11 (only to the extent expressly
provided therein), 12, 13 (through completion of the Sell-Off Period), 14, 16-18
(inclusive), 24, and 27, which shall survive the termination of this Agreement
for any reason.

13.  Limited Right to Sell-Off.
     In the event that this Agreement is terminated for any reason. Motorola
shall have, for a mutually agreed upon period ("Sell-Off Period") of not less
than ninety (90) calendar days following the effective date of termination, the
limited, one-time right to license and/or distribute copies of downloadable or
embedded Certified Applications, provided that such Certified Applications had
been sold to or requested by Customers on or before the effective date of
termination.

14.  Notice of Discontinuance
     In the event that Licensor desires to discontinue distribution, execution
or technical support of any Certified Application(s), a minimum one-hundred and
eighty (180) day prior notification shall be provided to Motorola to allow
phase-out of the Certified Application. This notification and phase-out period
may be shortened upon mutual consent of the parties.

                                       11

15.  Intellectual Property Rights.
     Nothing in this Agreement grants either Party an ownership or other
interest in the other Party's Intellectual Property Rights. In no event are any
rights, except the licenses expressly granted herein, in any real or
intellectual property transferred from one Party to the other pursuant to this
Agreement. Motorola shall own all proprietary rights, including copyrights
and/or trademarks, in and to any marketing materials created, modified or
otherwise prepared by or for Motorola which may contain Licensor's Intellectual
Property Rights and/or Licensor's Trademarks.

16.  Relationship of the Parties.
     Each of the Parties shall act as, and shall be, independent contractors in
all aspects of this Agreement. Neither Party will act or have authority to act
as an agent for the other Party for any purpose whatsoever. Nothing in this
Agreement will be deemed to constitute or create a joint venture, partnership,
pooling arrangement, or other formal business entity or fiduciary relationship
between Motorola and Licensor.

17.  Indemnification.
     Licensor shall indemnify and hold harmless Motorola, its affiliates,
subsidiaries and Customers, and its and their respective officers, directors,
employees, agents, successors and assigns (each an "Indemnified Party") from and
against any judgments, losses, damages, liabilities, costs or expenses
(including, but not limited to, reasonable attorneys' fees and legal expenses)
of any kind attributable to any use, distribution, or license of any
Application, including but not limited to costs, expenses, and attorney's fees
incurred by an Indemnified Party associated with or arising from: (i) any breach
or claimed breach of the above Licensor representations and warranties; (ii)
damage to the Supported Products or any portion thereof resulting from use of
any of the Applications; (iii) warranty or Customer support services performed
by Motorola with respect to any of the Applications or any Supported Products
damaged as a result of use of any of the Applications; (iv) recalling any
defective Applications; and (v) any third party claim or action brought against
an Indemnified Party alleging that any Application or any portion thereof (a)
infringes, misappropriates or violates in any manner, any intellectual property
right, right of publicity, right of privacy, moral right, or any other
proprietary right of a third party; or (b) contains material or information that
is fraudulent, deceptive, misleading, obscene, defamatory, trade libelous,
libelous, slanderous, or unlawfully harassing or injurious, or is in violation
of personal or property rights, regulation or law, or other common law or
statutory rights. The foregoing indemnity will be in addition to, and not in
lieu of, all other legal rights and remedies that Motorola may have. Licensor
agrees that it will, upon Motorola's request and at Licensor's expense, defend
or assist Motorola in the defense of any action brought against Motorola for
which Licensor has an indemnity obligation hereunder.

18.  Limitations of Liability.
     WITH RESPECT TO THE SUBJECT MATTER OF THIS AGREEMENT, NEITHER LICENSOR NOR
MOTOROLA SHALL BE LIABLE FOR ANY CONSEQUENTIAL, INDIRECT, INCIDENTAL, PUNITIVE
OR

                                       12

<PAGE>

SPECIAL DAMAGES OF ANY KIND OR CHARACTER. INCLUDING WITHOUT LIMITATION LOSS OF
REVENUE OR PROFITS. FAILURE TO REALIZE SAVINGS OR OTHER BENEFITS, OR LOSS OF
DATA OR USE, EVEN IF EITHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES. Except for Licensor's indemnity obligations under Section 17, neither
Party's liability under this Agreement shall exceed the amount of payments due
and payable to the Licensor under Section 7 and Exhibit C.

19.  Dispute Resolution.
     19.1 The Parties will attempt to settle any claim, dispute, controversy or
difference arising out of, or in relation to, or in connection with this
Agreement, or for breach thereof, through consultation and negotiation in good
faith and spirit of mutual cooperation. If those attempts fail to achieve a
settlement, then the dispute will be mediated by a mutually acceptable mediator
to be chosen by the Parties within forty-five (45) calendar days after written
notice by either Party demanding mediation. Neither Party may unreasonably
withhold consent to the selection of a mediator, and the Parties will share the
costs of mediation equally. The mediation hearing shall be conducted within
thirty (30) calendar days after the selection of the mediator. The Parties may
also agree to replace mediation with some other form of alternate dispute
resolution ("ADR"), such as neutral fact-finding or a mini-trial. Any mediation
or other ADR shall be conducted in the English language. Any dispute which
cannot be resolved between the Parties through negotiation, mediation or other
form of ADR within six (6) months of the date of the initial demand for ADR or
mediation by one of the Parties may then be submitted to the courts for
resolution.

     19.2 The use of any ADR procedures will not be construed under the
doctrines of laches, waiver or estoppel to affect adversely the rights of either
Party. Nothing in this Section 19 will prevent either Party from resorting to
judicial proceedings if interim relief from a court is necessary to prevent
serious and irreparable injury to that Party or to others. In addition, nothing
in this Section 19 shall be construed as applying to disputes regarding the
Intellectual Property Rights or trademarks of either Party (including but not
limited to Confidential Information), the enforcement of the Parties' respective
Intellectual Property Rights or trademarks, or the enforcement of the Parties'
respective obligations under this Agreement with respect to the other Party's
Intellectual Property Rights or trademarks.

20.  No Exclusivity.
     Each Party shall carry out its commitments under this Agreement in a manner
that reflects favorably upon the good name and goodwill of the other Party. The
Parties agree that the commitments under this Agreement are not exclusive and
that either Party may enter into similar agreements with third parties,
including either Party's competitors.

21.  Entire Agreement and Amendments.
     21.1 This Agreement, including any and all Exhibits, constitute the
complete and exclusive agreement between the Parties with respect to the subject
matter hereof, superseding and replacing any and all prior or contemporaneous
agreements, communications, and understandings, both written and oral, regarding
such subject

                                       13

<PAGE>

matter. Notwithstanding the foregoing, this Agreement shall not be interpreted
to supersede or replace any other written agreement between the Parties that
does not relate to the subject matter hereof. In the event of a conflict between
the Terms and Conditions of this Agreement and the terms and conditions of any
other written Agreement between the Parties, the Parties agree to negotiate in
good faith to resolve the conflict, except that in the event of a conflict
between the Terms and Conditions of this Agreement and the terms and conditions
of a click-accept agreement on the Motorola web site that is accepted by
Licensor subsequent to this Agreement and relates to the subject matter hereof,
the Terms and Conditions of this Agreement shall control.

     21.2 Motorola may, from time to time, modify the terms of this Agreement
by: (i) posting the revised agreement on Motorola's web site and notifying
Licensor of the change by e-mail; (ii) forwarding a copy of the revised
Agreement to Licensor, whether electronically or through a postal service; or
(iii) any other means reasonably calculated to inform Licensor of the terms of
the revised agreement. Unless Licensor objects to the revised agreement in
writing to Motorola within thirty (30) days of receiving notice of the change,
in which case no revision will take effect. Licensor will be deemed to have
accepted the terms of the revised Agreement and the as revised Agreement will
take effect and be biding on both parties at the end of Licensor's thirty (30)
day objection period. Subject to the foregoing, all other amendments to this
Agreement must be in a written document signed by authorized representatives of
both Parties.

22.  Assignment.
     Licensor may not assign this Agreement or any of its rights or obligations
hereunder without the express written consent of Motorola, which consent shall
not be unreasonably withheld. Motorola may assign this Agreement or any of its
rights or obligations hereunder; provided that the third party to whom the
rights or obligations will be assigned first agrees in writing to assume
Motorola's obligations under this Agreement. Notwithstanding any clause herein
to the contrary, Motorola is authorized to grant a limited sub-licensed right to
its Customers to use the Certified Applications, and/or resell or re-distribute
Supported Products that include any Certified Applications.

23.  Force Majeure.
     Neither Party shall be held responsible or liable for any losses arising
out of any delay or failure in performance of any part of this Agreement due to
any act of God, act of governmental authority, act of the public enemy or due to
war, riot, flood, civil commotion, insurrection, labor difficulty, severe or
adverse weather conditions, lack or shortage of electrical power, failure of
performance by any third party hosting service or equipment provided or
maintained by others, including general performance of the Internet itself, or
any other cause beyond the reasonable control of the Party delayed.

24.  Severability.
     If any one or more of the provisions of this Agreement is held to be
unenforceable under applicable law, (a) such unenforceability shall not affect
any other provision of this Agreement; (b) this Agreement shall be construed as
if said unenforceable provision had not been contained therein; and (c) the
Parties shall negotiate in good faith to

                                       14

<PAGE>

replace the unenforceable provision by a provision which has the effect nearest
to that of the provision being replaced.

25.  Governing Law.
     It is understood and agreed by both Parties hereto that the laws of the
United States and any other jurisdiction in which actions are taken in
performance of this Agreement shall be respected and observed. This Agreement
shall be construed and governed in accordance with the laws of the State of
Illinois, U.S.A., without regard to its conflict of law rules. Both Parties
consent to the jurisdiction of the State of Illinois, acknowledge that venue is
proper in the state and federal courts located in Cook County, Illinois, U.S.A.,

of the above.

     Notwithstanding the foregoing, the Parties agree that neither Motorola nor
any Customer shall be obligated to pay Licensor any additional royalty to
exercise Motorola's rights under Section 4.2 or Section 4.3 of the Agreement.

     2.2  Restrictions for Sublicense to Wireless Service Provider Customers.
Motorola shall require any wireless service provider Customer to which Motorola

     3.1  The payment made to Licensor for royalties earned during any Reporting
Period ("Licensor's Royalty") shall be the sum of the Certified Applications
Royalty and the Embedded Applications Royalty, if any, less any current or past
amounts due Motorola under Section 7 of the Agreement and/or Section 17 of the
Agreement. No payments shall be due to Licensor for Motorola's installation
and/or internal use of the Applications during testing, trials, pilot launches,
or other non-revenue generating tests or evaluation, or for Motorola's public
demonstrations of the Certified Applications to current or prospective Motorola
Customers and/or at trade shows, seminars, conferences, or wireless or
electronic industry events. Licensor's Royalty shall be paid to Licensor within
forty-five (45) calendar days of the end of any particular Reporting Period for
royalties earned during the particular Reporting Period. If there is a
disagreement relating to Licensor's Royalty, such disagreement will be resolved
mutually in accordance with Section 19 of the Agreement.

     3.2  Each payment made to Licensor shall be accompanied by a report
("Royalty Report") providing support for the payment. The Royalty Report
provided to Licensor shall include the quantity of each Certified Application,
identified by title or other appropriate identifier, licensed or distributed
during the Reporting Period and the price paid for each purchased Certified
Application. Motorola may alternatively or additionally make Licensor's Royalty
Report available to Licensor via a secure or password-protected connection over
Motorola's website, in which case Motorola shall not be obligated to accompany
Licensor's Royalty Report with each royalty payment.
