        <footnote id="F3">Each of the stock option grants have been vested; however, certain restrictions on the sale of the underlying shares of any options exercised is imposed on 600,000 options.  These restrictions are scheduled to lift on 120,000 options each of March 31, 2007, 2008, 2009, 2010 and 2011, although these restrictions are subject to being accelerated or deferred based on certain events of termination of Mr. Davis' employment agreement and/or a change in control event.  The restricted stock units vest in increments of 2,500 units on each of April 1, 2007, 2008, 2009, and 2010 with the final 2,500 units vesting on March 31, 2011 or upon the earlier occurrence of certain events of termination of Mr. Davis' employement agreement and/or a change in control event.</footnote>
        <footnote id="F4">The stock options expire variously through February 2016.  The restricted stock units expire in April 2016.  Exceptions to the stated expiration date are certain events of termination of Mr. Davis' employment agreement and/or a change in control event.</footnote>
