Explanation of Responses:

1. The RSUP1 award listed in Table II has been reported at 75% of the original grant amount, as that represents the minimum amount guaranteed to be paid out upon vesting. Because of performance targets achieved, the award was paid out on March 3, 2008, at a performance-adjusted rate of 125%. The shares coded "A" represent that portion attributable to this performance adjustment. The shares coded "F" were sold to cover income tax obligations associated with the payout.

2. 1 for 1

3. On February 19, 2008 the Board approved a March 3, 2008 performance-adjusted restricted stock unit grant to Mr. Pearson in the amount of 1,807 shares, of which 75% or 1,356 shares will be payable on March 3, 2011. 451 shares are subject to forfeiture if the performance goals are not met. The full grant can be adjusted upward by an additional 25% if the 3-year goals are achieved.

4. This transaction was performed in accordance with a 10b5-1 Plan signed by James F. Pearson on 5/26/2006.
