1280 through 1294.2 of the Code of Civil Procedure. If a dispute should arise
under this Agreement, either party may within ten (10) days make a demand for
arbitration by filing a demand in writing with the other. The parties may agree
upon one arbitrator, but in the event that they cannot agree, there shall be
three, one named in writing by each of the parties within ten (10) days after
demand for arbitration is given and a third chosen by the two appointed. Should
either party refuse or neglect to join in the appointment of the arbitrator(s)
or to furnish the arbitrator(s) with any papers or information demanded, the
arbitrator(s) are empowered by both parties to proceed ex parte. Arbitration
shall take place in the City of Los Angeles, County of Los Angeles, State of
California, and the hearing before the arbitrator(s) of the matter to be
arbitrated shall be at the time and place within said city as is selected by the
arbitrator(s). The arbitrator(s) shall select such time and place promptly after
his (or her) appointment and shall give written notice thereof to each party at
least 20 days prior to the date so fixed. At the hearing any relevant evidence
may be presented by either party, and the formal rules of evidence applicable to
judicial proceedings shall not govern. Evidence may be admitted or excluded in
the sole discretion of the arbitrator(s). Said arbitrator(s) shall hear and
determine the matter and shall execute and acknowledge their award in writing
and cause a copy thereof to be delivered to each of the parties. If there is
only one arbitrator, his decision shall be final, binding and conclusive upon
all the parties, and if there are three arbitrators the decision of any two
shall be binding and conclusive. The submission of a dispute to the
arbitrator(s) may be rendered by any Superior Court having jurisdiction; or such
Court may vacate, modify, or correct the ward in accordance with the prevailing
sections of the California Arbitration Act. If three arbitrators are selected
under the foregoing procedure but two of the three fail to reach an agreement in
the determination of the matter in question, the matter shall be decided by
three new arbitrators who shall be appointed and shall proceed in the same
manner, and the process shall be repeated until a decision is finally reached by
two of the three arbitrators selected. The costs of such arbitration shall be
borne equally by the parties or in such proportions as the arbitrator(s) shall
determine.

of this Agreement, and all other provisions hereof shall remain in full force
and effect.

Agreement, or to declare any rights, duties and obligations hereunder, the
prevailing party shall be awarded his costs of suit including reasonable
attorney's fees to be fixed by the Court.
