(4) This filing is being made to report the increase, effective June 20, 2005, in the minimum number of shares of common stock issuable under a shared performance stock award ("SPSA") for the fiscal 2004-2006 performance period.
(5) The number of shares ultimately received depends on the company's performance against specified performance targets. At the end of the performance period, the number of shares of stock and stock awards will be determined by adjusting upward or downward from a target in a range between 33% and 150%. The number reported herein is based on the 33% minimum. The final performance percentage on which the payout will be based, considering company performance metrics established for the performance period, will be determined by the board or a board committee in its sole discretion. Shares of stock are issued at the end of the performance period and as the stock awards vest over the following two years, provided that the reporting person remains continuously employed through the applicable vest date.
(6) One-third of the number of shares of common stock ultimately awarded under the SPSA will be distributed to the reporting person on or about August 31, 2006 (the "initial vest date"), an additional one-third shall vest and distributed to the reporting person on each of the first and second anniversaries of the initial vest date, provided that the Reporting Person remains continuously employed through the applicable vesting date.
