        <footnote id="F1">This award was approved by shareholders on May 25, 2007, and contains objective performance goals for purposes of the vesting of the shares based on the Company's attainment of either: (i) a specified adjusted earnings per diluted share target, or (ii) a specified Company stock price target, both of which are defined in the restricted stock agreement.  The measurement period for purposes of determining whether or not such shares will ultimately vest will be over a three-year period based principally on the Company's performance for its 2007, 2008, and 2009 fiscal years, and is expected to be determined in the first quarter following each of the respective fiscal years.  See the Company's 2006 Proxy statement for additional discussion of this matter.</footnote>
