and not disclose or use except in performance of its obligations under this
Agreement, confidential or proprietary information related to the other party's
("Disclosing Party") technology or business that the Receiving Party learns in
connection with this Agreement and any other information received from the
other, including without limitation, to the extent previously, currently or
subsequently disclosed to the Receiving Party hereunder or otherwise:
information relating to products or technology of the Disclosing Party or the
properties, composition, structure, use or processing thereof, or systems
therefor, or to the Disclosing Party's business (including, without limitation,
computer programs, code, algorithms, schematics, data, know-how, processes,
ideas, inventions (whether patentable or not), names and expertise of employees
and consultants, all information relating to customers and customer transactions
and other technical, business, financial, customer and product development
plans, forecasts, strategies and information), all of the foregoing,
"Confidential Information"). Neither party shall disclose the terms of this
Agreement to any third party without the prior written consent of the other
party. Each party shall use reasonable precautions to protect the other's
Confidential Information and employ at least those precautions that such party
employs to protect its own confidential or proprietary information.
"Confidential Information" shall not include information the Receiving Party can
document (a) is in or (through no improper action or inaction by the Receiving
Party or any affiliate, agent or employee) enters the public domain (and is
readily available without substantial effort), or (b) was rightfully in the
Receiving Party's possession or known by it prior to receipt from the Disclosing
Party, or (c) was rightfully disclosed to the Receiving Party by another person
without restriction, or (d) was independently developed by the Receiving Party
by persons without access to such information and without use of any
Confidential Information of the Disclosing Party. Each party, with prior written
notice to the Disclosing Party, may disclose such Confidential Information to
the minimum extent possible that is required to be disclosed to a governmental
entity or agency in connection with seeking any governmental or regulatory
approval, or pursuant to the lawful requirement or request of a governmental
entity or agency, provided that reasonable measures 

                                       6

 
are taken to guard against further disclosure, including without limitation,
seeking appropriate confidential treatment or a protective order, or assisting
the other party to do so.

               b.   The Receiving Party acknowledges and agrees that due to the
unique nature of the Disclosing Party's Confidential Information, there can be
no adequate remedy at law for any breach of its obligations hereunder, that any
such breach may allow the Receiving Party or third parties to unfairly compete
with the Disclosing Party resulting in irreparable harm to the Disclosing Party,
and therefore, that upon any such breach or any threat thereof, the Disclosing
Party shall be entitled to appropriate equitable relief in addition to whatever
remedies it might have at law and to be indemnified by the Receiving Party from
any loss or harm, including, without limitation, lost profits and attorney's
fees, in connection with any breach or enforcement of the Receiving Party's
obligations hereunder or the unauthorized use or release of any such
Confidential Information. The Receiving Party will notify the Disclosing Party
in writing immediately upon the occurrence of any such unauthorized release or
other breach. Any breach of this Section 10 will constitute a material breach of
this Agreement.

agent, employee or any other capacity to represent, act for, bind or otherwise
create or assume any obligation on behalf of the other party for any purpose
