Retirement Savings Plan

In 1994, the Company established a defined contribution plan, organized under Section 401(k) of the Internal Revenue Code, which allows employees who have completed at least one month of service and have reached age 18 to defer up to 50% of their pay on a pre-tax basis.  Effective April 1, 2007, the Company began matching 50% of the first 6% of employee contributions up to a maximum of $2,000 per employee.  As of April 1, 2010, the Company discontinued the employer contribution.
