     (c)  Engaging in Other Employment. During the term of this Agreement,
Employee shall during normal working hours (unless prevented by ill health or
accident and except during vacations and holidays) devote the whole of his time,
attention and abilities to carrying out his duties hereunder and Employee shall
not directly or indirectly render any services of a business, commercial, or
professional nature, to any other person or organization not designated by the
Board of Directors of the Company, whether for compensation or otherwise, or

and intellectual character, which gives the services a peculiar value, the loss
of which cannot be reasonably or adequately compensated in damages in an action

injunctive and other equitable relief to prevent a breach of this contract by
Employee.

deductions as are required to be made by law and shall be paid in equal
installments consistent with the Company's practices for its employees.

     (b)  Bonus. During the term of this Agreement, Employee shall be paid an
annual performance related bonus (the "Bonus") as agreed in writing from time to
time by Employee and the Board of Directors, including the affirmative approval
of the member of the Board elected by the Series E Preferred Stock, which bonus
shall not exceed 50% of Employee's annual salary.

such policies but in no event shall the Company be liable for premiums for such
life insurance in excess of $15,000 per year.

          (ii)   Vacation/Sick Days. Be provided with time off consistent with
that provided to other employees of the Company, however, Employee shall be
