Disability and Other Benefits. If the Executive suffers any illness, disability or incapacity which prevents the Executive from performing the Executive's duties hereunder, and such illness, disability or incapacity shall be deemed by a duly licensed physician -3- 4 (who may be the Executive's personal physician) to be permanent; or, if the Executive is unable to render full-time services to the Company of the character required hereunder for a period of six (6) consecutive months by reason of illness, disability or incapacity, and the Board has determined that the Executive has been permanently disabled; then, and in either of such events, the Executive shall render such advisory and consulting services to the Company as may be reasonably requested of the Executive by the Board and officers of the Company but only to the extent that the Executive is able to perform such services. In such event, the Executive shall be paid the amount of One Hundred Thirty-Two Thousand Dollars ($132,000) annually, payable in equal installments in conformity with the Company's normal payroll period. Such disability compensation shall commence upon the first day of the first month following the determination that the Executive's illness, disability or incapacity is permanent, and shall be paid for the balance of the Term even if the Executive's Employee's illness, disability or incapacity prevents the rendering by the Executive of any services to the Company and continues for the entire remaining Term.

The Executive's disability compensation hereunder shall be reduced by the amount of any disability insurance proceeds paid to or for the benefit of the Executive under any policy, the premiums for which have been paid by the Company.
