9.     EMPLOYEE BENEFIT PLANS

       The Company has a 401(k) defined contribution plan which permits participating employees in the United States to defer up to a maximum of 90% of their compensation, subject to limitations established by the Internal Revenue Service. Employees age 21 and older are eligible to contribute to the plan starting the first day of the following month of employment.  Participating employees are eligible to receive discretionary matching contributions and profit sharing, subject to certain conditions, from the Company.  In 2012 and 2013, the Company matched employee deferral contributions up to 4.5% of salary, which vested 100% immediately. No profit sharing has been paid under the plan. The Company recorded compensation expense of $61,000 and $62,000 for 2012 and 2013, respectively, related to its matching contributions to the plan. Certain of the Company’s employees located outside the United States participate in employee benefit plans that are statutory in nature.
