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. This stock option was issued in accordance with a 10b5-1 plan executed by Gary Leidich on August 18, 2005.
3. 1 for 1
4. These transactions reflect the extension of the expiration date of phantom stock from 3/1/2008 to "retirement" under arrangements approved by the Compensation Committee and reflect the movement of stock from the Phantom 3/05 account to the "retirement" account.
5. On February 19, 2008 the Board approved a March 3, 2008 performance-adjusted restricted stock unit grant to Mr. Leidich in the amount of 13,392 shares, of which 75% or 10,044 shares will be payable on March 3, 2011. 3,348 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.
