7.  EMPLOYEE BENEFIT AND SAVINGS PLANS

We have a 401(k) plan to provide retirement benefits for our employees.  As allowed under Section 401(k) of the Internal Revenue Code, the plan provides tax-deferred salary contributions for eligible employees and allows employees to contribute a percentage of their annual compensation to the plan on a pretax basis.  Employee contributions are limited to a maximum annual amount as set periodically by the Internal Revenue Code.  In 2011 and 2010 we matched 100% of pretax employee contributions on the first 3% of eligible earnings that are contributed by employees.  In 2009 up to 50% of pretax employee contributions were matched on the first 4% of eligible earnings that were contributed by employees.

* Due to the annual limit on eligible earnings imposed by the Internal Revenue Code

The plan allows employees who meet the age requirements and reach the plan contribution limits to make a catch-up contribution.  The catch-up contributions are not eligible for matching contributions.  In addition, the plan provides for discretionary matching contributions as determined by the Board of Directors.  There were no discretionary matching contributions made in 2011, 2010 or 2009.

We currently offer no postretirement or postemployment benefits to our employees.
