      At the recommendation of the President and CEO, no change was made in the
base salaries of executive officers for the 2006 fiscal year.  Base salaries
remain as established on December 17, 2004.

incentive compensation based upon:

      (1)   the level of achievement by the Company of targeted goals for
            earnings per share; 
      
      (2)   the level of achievement of specified individual performance
            objectives, including, by way of example, achievement of targeted
            levels of certain components of working capital, achievement of
            targeted rates of return on approved capital projects, increases in
            productivity and volume of product shipped, revenues derived from
            new products, and operating cost containment; and
      
      (3)   for executive officers with direct segment operating
            responsibility, achievement of targeted segment operating profit
            targets.
                                       -2-
      The Incentive Compensation Plan is attached to this Form 8-K as
Exhibit 10.3 and incorporated herein by reference.

      DEFERRED COMPENSATION PLANS

      The Company's deferred compensation plans were amended in various
respects to comply with the provisions of Section 409A of the Internal Revenue
Code of 1986, as amended (the "Code").  The President, Executive Vice
President, Administration, and Senior Vice President, Finance were authorized
to make such further amendments to the plans (without further Committee
approval) as they deem necessary or appropriate to maintain compliance with
Code Section 409A as final regulations and Internal Revenue Service
interpretations are issued.  

      In addition, the Company's 2005 Stock Incentive Plan was amended to
provide for the grant of options that are immediately exercisable.  Prior to
this amendment, all options had a minimum six-month holding period.
