available under the circumstances.

controversy shall be settled by final, binding arbitration in accordance with
the Employment Dispute Resolution Rules of the American Arbitration Association,
provided, however, that the impartial arbitrator shall be chosen as follows: if
the Company and Executive are unable to agree upon an impartial arbitrator
within five (5) days of a request for arbitration, the parties shall request a
panel of five (5) labor and employment arbitrators from the American Arbitration
Association and shall alternatively strike names until a single arbitrator
remains. Arbitration shall occur, if practicable, in Santa Barbara County,
California. Judgment upon the award rendered by the arbitrator may be entered in
any court having jurisdiction thereof. Depositions may be taken and other
discovery may be obtained during such arbitration proceedings to the same extent
as authorized in civil judicial proceedings, subject to any limitations placed


discovery by the arbitrator. The parties shall share equally in the costs of
conducting the arbitration and shall each pay their expenses, but the prevailing
party shall be entitled to recover its reasonable attorneys' fees.
Notwithstanding the foregoing, nothing herein shall preclude or limit the
Company from seeking injunctive relief from a court of competent jurisdiction.
Executive acknowledges and agrees that, by agreeing to this provision, he is
agreeing to arbitrate any claim relating to his employment, whether or not it
arises under the terms of this Agreement, that may arise under federal and state
laws including, but not limited to, claims arising under Title VII, the Age
Discrimination in Employment Act, the Americans with Disabilities Act and the

17. ENTIRE AGREEMENT. This Agreement, any stock option agreement, stockholder
buy-sell agreement and employee proprietary information agreement signed by
Executive contain the entire agreement of the parties and supersede and replace
any other Agreement. Except as provided herein, this Agreement may be modified
only by an agreement in writing signed by the party against whom enforcement of
any waiver, change, modification, extension or discharge is sought. Only the
Company's Board of Directors, or its designee, has the authority to modify this
Agreement on behalf of the Company.

IN WITNESS WHEREOF, the parties have duly executed this Agreement as of the day
and year first above written.
