arises between the parties relating to the interpretation or performance of
this Agreement or the grounds for the termination hereof, appropriate senior
executives (e.g. director or V.P. level) of each party who shall have the
authority to resolve the matter shall meet to attempt in good faith to

be referred to herein as the "Dispute Resolution Commencement Date."

shall be treated as confidential information developed for the purpose of
settlement and shall be exempt from discovery or production and shall not be
admissible. If the senior executives are unable to resolve the Dispute within
thirty (30) days from the Dispute Resolution Commencement Date, and either
party wishes to pursue its rights relating to such Dispute, then the Dispute
will be mediated by a mutually acceptable


                                      -5-



mediator appointed pursuant to the mediation rules of JAMS/Endispute within

selection of a mediator or the location of the mediation. Both parties will
share the costs of the mediation equally, except that each party shall bear
its own costs and expenses, including attorney's fees, witness fees, travel
expenses, and preparation costs. The parties may also agree to replace
mediation with some other form of non-binding or binding ADR.

through mediation within ninety (90) days of the Dispute Resolution
Commencement Date, unless otherwise mutually agreed, shall be submitted to
final and binding arbitration under the then current Commercial Arbitration
Rules of the American Arbitration Association ("AAA"), by three (3)
arbitrators in Santa Clara County, California. Such arbitrators shall be
selected by the mutual agreement of the parties or, failing such agreement,
shall be selected according to the aforesaid AAA rules. The arbitrators will
be instructed to prepare and deliver a written, reasoned opinion stating
their decision within thirty (30) days of the completion of the arbitration.
The prevailing party in such arbitration shall be entitled to expenses,
including costs and reasonable attorneys' and other professional fees,
incurred in connection with the arbitration (but excluding any costs and fees
associated with prior negotiation or mediation). The decision of the
arbitrator shall be final and non-appealable and may be enforced in any court
of competent jurisdiction. The use of any ADR procedures will not be
construed under the doctrine of laches, waiver or estoppel to adversely
affect the rights of either party.

         6.3   COURT ACTION. Any Dispute regarding the following is not
required to be negotiated, mediated or arbitrated prior to seeking relief
from a court of competent jurisdiction: breach of any obligation of
confidentiality; infringement, misappropriation, or misuse of any
intellectual property right; any other claim where interim relief from the
court is sought to prevent serious and irreparable injury to one of the
parties or to others. However, the parties to the Dispute shall make a good
faith effort to negotiate and mediate such Dispute, according to the above
procedures, while such court action is pending.

         6.4   CONTINUITY OF SERVICE AND PERFORMANCE. Unless otherwise agreed
in writing, the parties will continue to provide service and honor all other
commitments under this Agreement and each Ancillary Agreement during the
course of dispute resolution pursuant to the provisions of this Article 6
with respect to all matters not subject to such dispute, controversy or
claim.
