        <footnote id="F1">The restricted stock was awarded to Mr. Brown when he rejoined the Company in 2008 to become effective on February 18, 2009 subject to shareholder approval at annual shareholder meeting on May 1, 2008 and to his continued employment on such date, which conditions have been satisfied. The number of restricted shares granted was determined by dividing the amount of $5,000,000 by the average market value per share for the 20 trading days immediately preceding February 18, 2009.</footnote>
        <footnote id="F2">The restricted stock will vest fully if on or before February 18, 2013, the Company's average closing share price over any 20 consecutive trading days is at least $40 per share. In addition, a portion of the restricted stock vests upon a change of control (based on the share price immediately prior to the change of control) or retirement or February 18, 2013 (based on the average share price for the previous 20 trading days), where (1) none of the restricted stock vests if the price is less than an amount equal to the larger of $16.20 and $3.87, the 20-day average price used to determine the number of shares for the restricted stock grant, (2) 20% vests if the price is $20.96, (3) 40% vests if the price is $25.72, (4) 60% vests if the price is $30.48, (5) 80% vests if the price is $35.24, and (6) all of the restricted stock vests if the price is $40 or more, with interpolated vesting if the price is between such points.</footnote>
        <footnote id="F3">Any restricted stock that remains unvested after voluntary termination (other than retirement), termination for cause, or February 18, 2013 shall be forfeited. Restricted stock may not be disposed of until the later of February 18, 2013 and one year after termination of employment.</footnote>
