9.1 Arbitration Generally. Executive and the Company expressly agree that, to the extent permitted by law and to the extent that the enforceability of this Agreement is not thereby impaired, any and all disputes, controversies or claims between Executive and the Company, including, without limitation, those arising out of or concerning Executive’s employment by the Company or its termination or this Agreement, and including, without limitation, claims by Executive against the Board of Directors or any employees of the Company, whether arising under theories of liability or damages based on contract, tort or statute, shall be determined exclusively by final and binding arbitration before a single arbitrator in accordance with the National Rules For the Resolution of Employment Disputes of the American Arbitration Association, or successor rules then in effect, and that judgment upon the award of the arbitrator may be rendered in any court of competent jurisdiction. Claims subject to exclusive final and binding arbitration under this Agreement include, without limitation, claims that otherwise could be tried in court to a jury in the absence of this Agreement. Such claims include, without limitation, statutory claims for employment discrimination based on race, color, national origin, sex, religion, disability, age, harassment of any type, and other statutory or constitutional claims for employment discrimination; claims for wrongful termination including employment termination in violation of public policy; and claims for personal injury including, without limitation, defamation, fraud, and infliction of emotional distress.

The arbitration shall be held in Los Angeles, California, and this Agreement shall be construed according to the substantive law of the State of California as provided in this Section IX.

9.3 AAA Arbitration.

The arbitration shall be administered by the American Arbitration Association, and the arbitrator shall be selected from a list of arbitrators provided by the American Arbitration Association following a request by the party seeking arbitration for a list of five retired or former jurists with substantial professional experience in employment matters. The arbitration shall be conducted under the procedures applicable to arbitrations in the state of California. The arbitrator’s authority and jurisdiction shall be limited to determining the dispute in arbitration in conformity with law, to the same extent as if such dispute were determined as to liability and any remedy by a court without a jury. The arbitrator shall render an award which shall include a written statement of opinion setting forth the arbitrator’s findings of fact and conclusions of law.

9.4 Costs of Arbitration.

The Company or its successor shall pay the costs of arbitration including, without limitation, attorneys’ fees and costs, and fees and costs of any experts except that, if any party prevails on a statutory claim that entitles the prevailing party to a reasonable attorneys’ fee (with or without expert fees) as part of the costs, the arbitrator may award reasonable attorneys’ fees (with or without expert fees) to the prevailing party in accord with such statute.

9.5 Authority of Arbitrator.

Any controversy over whether a dispute is an arbitrable dispute or as to the interpretation or enforceability of this Section IX with respect to such arbitration shall be determined by the arbitrator.

9.6 Ongoing Rights and Obligations.

Executive acknowledges that the Company and Executive have ongoing rights and obligations relating to intellectual property, confidential information and non-competition with the Company, together with fiduciary rights and obligations, which will survive the termination of Executive’s employment with the Company. The Company and Executive agree that nothing in this Agreement shall waive or otherwise preclude any otherwise available right to temporary restraining orders or other injunctive relief for any breach or threatened breach of any of these obligations. Executive understands that injunctive relief may include, but shall not be limited to, restraining continuing breaches of such obligations. Any such injunctive proceedings shall be without prejudice to any rights the Company or Executive may have under this Agreement to obtain relief in arbitration with respect to such matters.

10.1 Governing Law.

This Agreement will be governed by the laws of the State of California, applicable to agreements made and to be performed entirely within such state.

10.2 Entire Agreement.

Any change to the at-will terms of this Agreement must be executed in writing and signed by Executive and the Compensation Committee of the Board of Directors of the Company.

10.3 Successors/Assigns.

This Agreement will be binding upon Executive’s heirs, executors, administrators, and other legal representatives and will be for the benefit of the Company and its respective successors and assigns.
