9. Termination: You may be terminated with or without Cause during the Term. “Cause” shall mean (i) a documented repeated and willful failure by you to perform your duties, (ii) your conviction or entry of a plea of nolo contendere for fraud, misappropriation or embezzlement, or any felony or crime of moral turpitude (iii) willful material violation of a policy which is directly and materially injurious to the Company or any subsidiary of the Company, and (iv) your material breach of this Agreement or the Company’s Employee Nondisclosure, Nonsolicitation, Noncompetition and Assignment Agreement entered into in connection herewith. With respect to subsections (i), (iii) and (iv) above, Cause shall exist only after written notice of such failure, violation or breach is delivered to you and you shall have failed to cure such violation or breach within 30 days after such notice, if curable. For purposes of this definition, no act or failure to act on your part shall be considered “willful” unless done or omitted not in good faith and without reasonable belief that the action or omission was in the best interest of the Company or any of its Subsidiaries or Affiliate.
