Information. Each party shall obtain the other's consent prior to any
publication, presentation, public announcement or press release concerning the
existence or terms and conditions of this Agreement.

         10.2 DEFINITION OF CONFIDENTIAL INFORMATION. 'Confidential Information'
means the terms and conditions of this Agreement, the existence of the
discussions between the parties, any information disclosed in connection with
the development and integration projects being undertaken as described in
Section 2 above, and any proprietary information a party considers to be
proprietary, including but not limited to, information regarding each party's
product plans, product designs, product costs, product prices, finances,
marketing plans, business opportunities, personnel, research and development
activities, know-how and pre-release products; provided that information
disclosed by the disclosing party ('Disclosing Party') in written or other
tangible form will be considered Confidential Information by the receiving party
('Receiving Party') only if such information is conspicuously designated as
'Confidential,' 'Proprietary' or a similar legend. Information disclosed orally
shall only be considered Confidential Information if: (i) identified as
confidential, proprietary or the like at the time of disclosure, and (ii)
confirmed in writing within thirty (30) days of disclosure. Confidential
Information disclosed to the Receiving Party by any affiliate or agent of the
Disclosing Party is subject to this Agreement.

         10.3 NONDISCLOSURE. The Receiving Party shall not disclose or use,
except as permitted under this Agreement, the Confidential Information to any
third party other than employees and contractors of the Receiving Party who have
a need to have access to and knowledge of the Confidential Information solely
for the Purpose authorized above. The Receiving Party shall have entered into
non-disclosure agreements with such employees and contractors having obligations
of confidentiality as strict as those herein prior to disclosure to such
employees and contractors to assure against unauthorized use or disclosure.

         10.4 EXCEPTIONS TO CONFIDENTIAL INFORMATION. The Receiving Party shall

possession of or known to the Receiving Party without any obligation of
confidentiality prior to receiving it from the Disclosing Party; (ii) is, or
subsequently becomes, legally and publicly available without breach of this
Agreement; (iii) is rightfully obtained by the Receiving Party from a source
other than the

                                     Page 12

Disclosing Party without any obligation of confidentiality; (iv) is developed by
or for the Receiving Party without use of the Confidential Information and such
independent development can be shown by documentary evidence; and (v) becomes
available to the Receiving Party by wholly lawful inspection or analysis of
products offered for sale. Further, the Receiving Party may disclose
Confidential Information pursuant to a valid order issued by a court or
government agency, provided that the Receiving Party provides the Disclosing
Party: (a) prior written notice of such obligation; and (b) the opportunity to
oppose such disclosure or obtain a protective order.

         10.5 RETURN OR DESTRUCTION OF CONFIDENTIAL INFORMATION. Upon written
demand by the Disclosing Party, and in any event upon termination of this
Agreement, the Receiving Party shall: (i) cease using the Confidential
Information, (ii) return the Confidential Information and all copies, notes or
extracts thereof to the Disclosing Party within seven (7) days of receipt of
demand; and (iii) upon request of the Disclosing Party, certify in writing that
the Receiving Party has complied with the obligations set forth in this

         10.6 INDEPENDENT DEVELOPMENT AND RESIDUALS. The terms of
confidentiality under this Agreement shall not be construed to limit either
party's right to develop independently or acquire products without use of the
other party's Confidential Information. The Disclosing Party acknowledges that
the Receiving Party may currently or in the future be developing information
internally, or receiving information from other parties, that is similar to the
Confidential Information. Accordingly, except as provided in this Agreement,
neither party shall be prohibited from developing or having developed for it
products, concepts, systems or techniques that are similar to or compete with
the products, concepts, systems or techniques contemplated by or embodied in the
Confidential Information provided that the Receiving Party does not violate any
of its obligations under this Agreement in connection with such development.
Further, subject to the other restrictions and limitations contained in this
Agreement, the residuals resulting from access to or work with such Confidential
Information shall not be subject to the confidentiality obligations contained in
this Agreement. The term 'residuals' means non-specific information in
non-tangible form, which may be retained by persons who have had access to the
Confidential Information, including general ideas, concepts, know-how or
techniques contained therein. Neither party shall have any obligation to limit
or restrict the assignment of such persons or to pay royalties for any work
resulting from the use of residuals.
