prior agreement from its employees, agents or consultants to whom disclosure is
to be made to hold in confidence and not make use of such information for any
purpose other than those permitted by this Agreement. Each party will use at
least the same standard of care as it uses to protect its own most confidential
information to ensure that such employees, agents or consultants do not disclose
or make any unauthorized use of such Confidential Information. Each party will
promptly notify the other upon discovery of any unauthorized use or disclosure
of the Confidential Information. Notwithstanding any other provision in this
Agreement to the contrary, the obligations set forth in this section shall
survive any termination or expiration of this Agreement for a period of ten
years thereafter.

               12.2 EXCEPTIONS. The obligations of confidentiality contained in
this section will not apply to the extent that it can be established by the
receiving party by competent proof that such Confidential Information:

                      (a) was already known to the receiving party, other than
under an obligation of confidentiality, at the time of disclosure by the other
party;

                      (b) was generally available to the public or otherwise
part of the public domain at the time of its disclosure to the other party;

                      (c) became generally available to the public or otherwise
part of the public domain after its disclosure and other than through any act or
omission of the receiving party in broach of this Agreement;

                      (d) was disclosed to the receiving party, other than under
an obligation of confidentiality, by a third party which had no obligation to
the other party not to disclose such Information to others.

               12.3 AUTHORIZED DISCLOSURE. Each party may disclose the
Confidential Information to the extent such disclosure is reasonably necessary
in filing or prosecuting patent applications, prosecuting or defending
litigation or complying with applicable governmental regulations, provided that
if such party is required to make any such disclosure of the Confidential
Information it will to the extent practicable give reasonable advance notice to
the other party of such disclosure requirement and, except to the extent
inappropriate in the case of patent applications, will use its best efforts to
secure confidential treatment of such information required to be disclosed. The

request of the other party, or upon the reasonable determination by the other
party that the receiving Party no longer has a need for such information. Each
party agrees to notify the other party if it becomes aware of any use of the
information that is not authorized by this Agreement.

event of a breach of this Section by such party or any of its officers,
directors, agents and/or employees, the other party will suffer irreparable
damages that cannot be fully remedied by monetary damages. Each party therefore
agrees that the other party shall be entitled to seek injunctive relief against
any such breach in any court of competent jurisdiction. The rights of each party
under this Section shall not in any way be construed to limit or restrict its
rights to seek or obtain other damages or relief available under this Agreement
or applicable law.

               12.6 INDEPENDENT DEVELOPMENT. The terms of this Section shall not
be construed to limit a party's right to independently develop or acquire
products which are similar in functionality to those of the other party so long
as such development or acquisition is made without the use of the Confidential
Information of the other Party. Both parties acknowledge that each of them may
currently or in the future be developing information internally, or receiving
information from other parties, that is similar to the Confidential Information
of the other. Nothing in this Agreement will be construed as a representation or
agreement that the receiving party will not develop or have developed for its
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.
