CASH INCENTIVE: $150,000 per year at 100% of goals. Goals to be mutually agreed upon between the Board and yourself. This incentive will be uncapped, so that if goals are exceeded, the cash incentive can be larger than $150,000 per year. ADDITIONAL BONUS: You will receive an additional bonus of $50,000 as an incentive to move towards an IPO as quickly as possible. This cash bonus will be payable on the first day of your employment. SHARE OWNERSHIP: Cupertino Electric will offer to sell you 301,278 shares (representing approximately 1% of the shares outstanding) at a price of $7.50 per share. These shares will be paid for with a note to Cupertino Electric at prime and secured by the stock and will vest at 25% per year for four years. The first 25% of the shares offered will become fully vested the day the company becomes public if earlier than one year from the start of your employment. You will also be asked to sign a form of shareholder agreement in connection with your shareholding which will provide for the vesting through repurchase rights and for other terms comparable to those of other shareholder executives in the company. It is our intent to also establish an employee stock option program in which you would be eligible for periodic option grants. VEHICLE: An automobile will be provided in accordance with the Company's auto leasing policy. The monthly lease rate for your position is $800.00 per month. 2 [LOGO] Richard Powers June 30, 2000 Page 2 MEDICAL INSURANCE: You and your family will be eligible for major medical insurance as carried by CEI.
