        <footnote id="F1">A Form 4 showing an Award of 100 shares was erroneously filed for this reporting person.  The balance of shares should be 8,501 as shown here.  There was no new transaction or award granted that would have required a Form 4 filing.  This Amendment is filed to negate the effect of the Form 4 filed in error.</footnote>
