Executive shall report directly to the President. 1.3 Executive agrees to devote his primary business time, energies, skills, efforts and attention to his duties hereunder, and will not, without the prior written consent of the Company, which consent will not be unreasonably withheld, render any material services to any other business concern. Executive will use his best efforts and abilities faithfully and diligently to promote the Company's business interests. 1.4 Except for routine travel incident to the business of the Company, Executive shall perform his duties and obligations under this Agreement principally from an office provided by the Company in Camarillo, California, or such other location, as the President may from time to time determine. 2.

The base salary shall be payable in installments throughout the year in the same manner and at the same times the Company pays base salaries to other executive officers of the Company. In the event that Executive's employment is terminated pursuant to SECTION 2(E), above, the Company shall continue to pay Executive's then-current base salary for a period of 9 months following the effective date of such termination, and Executive shall retain only those options described in SECTION 3.4, below, that have vested prior to the effective date of such termination. Notwithstanding the foregoing, the Company shall not be obligated to pay Executive any amounts hereunder following the termination of Executive's employment pursuant to SECTION 2(E), above, from and after any time that Executive accepts an employment or consulting position with any person or entity that is determined by the President, in the exercise of his reasonable discretion, to be a competitor of the Company. 3.2 In addition to the Base Salary to be paid to Executive hereunder, the Company shall pay a performance bonus (the "BONUS") determined in accordance with a management incentive plan (the "MIP") to be approved in a resolution adopted by the Compensation Committee. The management incentive plan will provide for the payment of an annual Bonus equal to 30% of the then current base salary upon achieving the "target" objectives set forth in the MIP, and payments of such lesser or greater amounts upon achieving results less than or greater than the "target" objectives as shall be contained in the MIP. 3.3 Executive shall be granted an option to purchase 30,000 shares of Common Stock at a per share exercise price equal to the "fair market value" of such shares on the Effective Date (as defined in the Company's 2000 Stock Incentive Plan (the "STOCK PLAN")). The Options shall be issued pursuant to the terms of the Stock Plan, and shall vest as to 25% of the Options on the first anniversary of the date of grant, and as to 1/48th of the Option on the last day of each calendar month thereafter until fully vested. The option agreement will provide for the acceleration of all vesting upon a change of control, as defined in the option agreement, that occurs prior to the termination of this Agreement. In addition, all previous grants of options to the Executive shall be modified so that such options shall also accelerate and become fully vested upon a change of control. 3.4 Executive shall be entitled to reimbursement from the Company for the reasonable costs and expenses which he incurs in connection with the performance of his duties and obligations under this Agreement in a manner consistent with the Company's practices and policies as adopted or approved from time to time by the President for executive officers. 2 3.5 The Company may deduct from any compensation payable to Executive the minimum amounts sufficient to cover applicable federal, state and/or local income tax withholding, old-age and survivors' and other social security payments, state disability and other insurance premiums and payments. 4. OTHER BENEFITS. During the term of his employment hereunder, Executive shall be eligible to participate in all operative employee benefit and welfare plans of the Company then in effect from time to time and in respect of which all executive officers of the Company generally are entitled to participate ("COMPANY EXECUTIVE BENEFIT PLANS"), including, to the extent then in effect, group life, medical, disability and other insurance plans, all on the same basis applicable to employees of the Company whose level of management and authority is comparable to that of Executive. 5.
