(b) Executive agrees to perform such duties and render such services to the best of his ability, devoting thereto his entire professional time, attention and energy exclusively to the business and affairs of the Company and its affiliates, as its business and affairs now exist and as they hereafter may be changed, and shall not during the term of his employment hereunder be engaged in any other business activity, whether or not such business activity is pursued for gain or profit; provided, however, that Executive may serve (i) on civic or charitable boards or committees and (ii) with the prior written approval of the Board, boards of corporations or business enterprises, in each case so long as such activities do not interfere with the performance of Executive’s obligations under this Agreement.

3. Compensation of Executive. As compensation for the services to be performed under this Agreement:

(a) Base Salary. Effective as of the date of this Agreement, Executive shall be paid a base salary at the initial annual rate of $264,000, payable in installments consistent with the Company’s payroll practices, and subject to normal withholding.

The parties recognize that claims, controversies and disputes may arise out of this Agreement with respect to Executive’s employment, termination of employment, or other terms of this Agreement or based on common law or statute, either during the existence of the employment relationship or afterwards. The parties agree that should any such claim, controversy or dispute arise, the parties will use their best efforts to resolve such dispute informally, between them. In the event that any such claim, controversy or dispute between Company and Executive cannot be resolved within thirty (30) days after either party first gives notice in writing that any such claim, controversy or dispute exists, either party may then refer the matter to arbitration before JAMS/ENDISPUTE pursuant to its rules for resolution of employment disputes.

The parties hereby agree that referral to arbitration shall be the sole recourse of either party under this Agreement with respect to any such claim, controversy or dispute and that the decision of the arbitrator shall be binding on the parties in accordance with applicable law; provided, however, that nothing in this Section 5 shall be construed as precluding either party from bringing an action for injunctive relief or other equitable relief. The parties shall keep confidential the existence of each such the claim, controversy or dispute from third parties (other than arbitrator), and the determination thereof, unless otherwise required by law. Except as provided in the following sentence, such decision rendered by the arbitrator shall be final and conclusive and may be entered in any court having jurisdiction thereof as a basis of judgment and of the issuance of execution for its collection. In rendering his or her decision, the arbitrator shall be bound to follow California or Federal law, as applicable, in the same manner as would a court of law. Any claim that the arbitrator made a mistake or error in determining or applying the appropriate law shall be subject to judicial review.
