ITEM 1.01. ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT On February 2, 2006, the shareholders of the Registrant approved the Incentive Compensation Plan For Executive Officers ("ICP"), a new cash incentive compensation ("bonus") plan for the executive officers of the Registrant. The ICP was approved by the Human Resources and Compensation Committee ("Committee") of the Registrant's Board of Directors on November 9, 2005. Commencing with fiscal year 2006, Registrant intends to divide each executive officer's bonus target between the ICP and the existing Performance Compensation Plan. Under the ICP, the Committee approved the fiscal year 2006 bonus targets for the executive officers, as follows: V.L. Richey and C.J. Kretschmer - 20% of fiscal year 2006 total cash compensation; G.E. Muenster and A.S. Barclay - 15% of fiscal year 2006 total cash compensation. The actual bonuses to be paid under the ICP may vary from the bonus targets based upon the application of a fiscal year earnings per share matrix, which was also approved by the Committee. See the Form 8-K dated December 15, 2005.
