   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;We grant various forms of equity based awards to directors, officers and other key employees.
   These equity based awards consist primarily of stock options, restricted stock awards and
   restricted stock units. The fair value of each stock option granted is estimated on the date of
   grant using a Black-Scholes option pricing model. The fair value of restricted stock awards and
   units is based on the market price of our common stock on the date of grant.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;We also have an Employee Stock Purchase Plan (&amp;#8220;ESPP&amp;#8221;) available for eligible employees to
   purchase shares of our common stock. Effective January&amp;#160;1, 2010, the ESPP provides for shares to be
   purchased: (i)&amp;#160;on June&amp;#160;30 of each year at a 15% discount of the fair market value of our common
   stock on January 1 or June&amp;#160;30, whichever is lower, and (ii)&amp;#160;on December&amp;#160;31 of each year at a 15%
   discount of fair market value of our common stock on July 1 or December&amp;#160;31, whichever is lower.
   Also effective January&amp;#160;1, 2010, an employee may not contribute more than $5,000 in either of the
   six-month measurement periods described above or $10,000 annually.
