(ii)the Executive's willful failure to comply with any valid and legal directive of the Board or the person to whom Executive reports;

(iii)the Executive's engagement in dishonesty, illegal conduct, or misconduct, which is, in each case, injurious to the Company or its affiliates, as reasonably determined by the Board;

(viii)the Executive's engagement in conduct that brings or is reasonably likely to bring the Company negative publicity or into public disgrace, embarrassment, or disrepute.

For purposes of this provision, none of the Executive's acts or failures to act shall be considered “willful” unless the Executive acts, or fails to act, in bad faith or without reasonable belief that the action or failure to act was in the best interests of the Company. The Executive's actions, or failures to act, based upon authority given pursuant to a resolution duly adopted by the Board or upon the advice of counsel for the Company shall be conclusively presumed to be in good faith and in the best interests of the Company.

(c)For purposes of this Agreement, “Good Reason” shall mean the occurrence of any of the following, in each case during the Employment Term without the Executive's prior written consent:

deemed to have waived the Executive's right to terminate for Good Reason with respect to such grounds.

5.2Expiration of Term, Termination by Company Without Cause or Termination by Executive for Good Reason. The Employment Term and the Executive's employment hereunder may be terminated by the Executive for Good Reason or by the Company without Cause or on account of the Company’s failure to renew the Agreement in accordance with Section 1.
