Employee 401(k) Plan

12.  Employee 401(k) Plan

In December 1998, the Company adopted a 401(k) Plan (the "Plan"), to provide retirement benefits for employees. As allowed under Section 401(k) of the Internal Revenue Code, the Plan provides tax-deferred salary deductions for eligible employees. Employees may contribute up to 15% of their annual compensation to the Plan, limited to a maximum annual amount as set periodically by the Internal Revenue Service. In addition, the Company may make discretionary/matching contributions. During 2012 and 2011, the Company contributed a total of approximately $51,400 and $43,200, to the Plan, respectively.
