Compensation; C. Benefit Programs as outlined below:

A.   Fixed Salary shall be at the rate of $66,000 per year, payable

time for executives of the Company subject to applicable eligibility
requirements. Benefit Programs may be changed as business needs dictate. A
summary of our current programs has been given to you.
