        <footnote id="F1">On March 22, 2007, the Company granted 2000 restricted stock units (the &quot;RSUs&quot;) to the reporting person.  The grant was rescinded on February 1, 2008.  The RSUs reflected in Table II were granted on March 25, 2008 under the Company's 2008 Non-Employee Directors' Stock Plan, subject to the shareholders approval of the plan on May 22, 2008, to replace the forfeited grant.  The RSUs are generally scheduled to vest on March 25, 2011.  The RSUs were forfeited on May 22, 2008 upon Ms. Mayer's departure from the Board of Directors.</footnote>
