If the Company determines in good faith that the Executive is Disabled, it may give to the Executive written notice in accordance with Section 14 of its intention to terminate the Executive’s employment. In such event, the Executive’s employment with the Company shall terminate effective on the 30^th day after receipt of such notice by the Executive (the “Disability Effective Date”), provided that, within the 30 days after such receipt, Executive shall not have returned to full-time performance of the Executive’s duties.

(b) Cause. The Company may terminate the Executive’s employment during the Term for Cause. For purposes of this Agreement, “Cause” shall be determined by the Committee in exercise of good faith and reasonable judgment and shall mean (i) a material violation of Company policy or a material breach by the Executive of the Executive’s duties and obligations (other than as a result of incapacity due to physical or mental illness) that is demonstrably willful and deliberate on the Executive’s part, committed in bad faith or without reasonably belief that the action or inaction that constitutes such breach is in the best interests of the Company, and, if subject to being effectively remedied, is not remedied in a reasonable period of time (specified by the

Company) after receipt of written notice from the Company specifying such breach of violation (“Notice of Breach”); or (ii) the conviction of the Executive of a felony.

If the Company delivers a Notice of Breach to the Executive describing the situation to be remedied and Executive fails to remedy such violation or breach within 60 days, then a Notice of Termination delivered to the Executive subsequent to the Notice of Breach shall become effective in accordance with the provisions specified below.

(c) Notice of Termination: Any termination by the Company for Cause, or by the Executive, shall be communicated by Notice of Termination to the other party hereto given in accordance with Section 14.

The Company may not terminate the Executive’s employment for Cause after the Executive has delivered a Notice of Termination for Good Reason (or in the case following a Change in Control, for any reason), nor may the Executive terminate employment with Company for Good Reason (or in the case following a Change in Control, for any reason) after Company has delivered a Notice of Termination to the Executive.
