EMPLOYEE BENEFIT PLAN
 
In 1994, we established a qualified 401(k) Retirement Plan (the “Plan”) under which employees are allowed to contribute certain percentages of their pay, up to the maximum allowed under Section 401(k) of the Internal Revenue Code. Our contributions to the Plan are at the discretion of the Board of Directors. Our contributions were approximately $233,000, $239,000, and $239,000 in 2012, 2011 and 2010, respectively.
