        <footnote id="F1">These units are awarded pursuant to the Restoration Supplemental Retirement Plan (the &quot;Plan&quot;).  Mr. Hemphill has elected to defer receipt of compensation otherwise payable to him in the form of stock units, the basis of which is determined to be the Company closing stock price on the last day of each month.  The Plan allows for distribution upon a date(s) specified by the participant in the event of the participant's unforeseeable emergency, death or termination of employment.  This amount represents Mr. Hemphill's January 2006 deferral.</footnote>
