Your employment with the Company is at-will meaning both you and the Company can end the employment relationship at any time and for any reason.

Your semi-monthly salary will be $9,375.00, which is $225,000.00 annually. Beginning in 2011, you will be eligible for a discretionary annual bonus targeted at 40% of your base salary based on company financial results and personal performance. Annual bonus amounts are approved by the Compensation Committee in March of the following year, i.e., March 2012 for 2011 performance.

You will have the opportunity for future incentive equity grants if and when an equity plan is developed for similarly situated employees.

Effective on your start date, you will be eligible to participate in the Company’s employee benefit plans for health, dental, vision, life insurance, voluntary life insurance, AD&D, and short-term and long-term disabilities.

In the event the Company terminates your employment “without cause”; the Company agrees to pay you separation pay equal to six months of your then-current salary and will reimburse you for the monthly premiums for elected COBRA coverage for a period of up to six months. After six months, you will be eligible to be included in the plan set up for others in your salary grade. For purposes of this agreement, “without cause” shall mean for any reason other than willful misconduct, fraud, breach of ethics and other published policies of the Company.
