The bonus formula was applied to the Company’s improvement in economic profit from 2004 to 2005. The number of shares granted was determined based on the closing market price of the Company’s common stock on April 13, 2006, which was $24.50 per share.

The restricted stock vests in full or in part based on the Company’s satisfaction of earnings per share-based performace critieria, which are described more fully in the form of restricted stock grant agreement.
