Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

     In connection with the adoption of a new fiscal year described below, the Board of Directors determined that the Registrant's cash incentive program during the resulting 6 month transition period ending December 31, 2011 would be based on its current annual program. The transition period program, which, like the annual program, will be based on growth in Modified Economic Profit ("MEP") (as defined in the second paragraph of Item 5.02(e)(1) of Registrant's Current Report on Form 8-K filed November 11, 2009, which second paragraph is incorporated herein by reference), will use 50% of MEP for fiscal 2011as a base (the "Base") from which growth in MEP will be measured. The target for growth in MEP is 50% of the increase amount that was targeted for fiscal 2011. Potential awards for named executive officers as a percentage of transition period base pay if growth in MEP over the Base during the transition period is at the target level are as follows: Timothy W. Newkirk -- 100%; Donald Coffey, Ph.D. -- 70%: Randy Schrick -- 70%. No incentive compensation is payable if growth in MEP is less than 80% of target. If growth in MEP exceeds 110% of the growth target, 125% of target incentive compensation is payable.

     The Registrant's board also adopted an amendment to Section 2.1 of the Registrant's bylaws changing the date of the annual meeting of stockholders, commencing in 2012, from the second Wednesday in October, or such other day as shall be determined in advance by the Board of Directors, to the last Thursday of May, or such other day as shall be determined in advance by the Board of Directors. The annual meeting in 2011 will be held on October 20, 2011. Stockholders who intend to present proposals for inclusion in the Registrant's proxy statement for the annual meeting of stockholders to be held in 2012 must forward them to the Registrant so that they are received on or before January 6, 2012. In addition, proxies solicited by management in connection with the 2012 annual meeting may confer discretionary authority to vote on matters which are not included in the proxy statement but which are raised at the annual meeting by stockholders, unless the Registrant receives written notice of the matter on or before March 21, 2012.

     Sections 2.1 and 11.2 of the Bylaws, as amended, are set forth below.

          Section 2.1. Annual Meetings. - The annual meeting of the stockholders for the election of Directors and for the transaction of such other business as may be properly brought before the meeting shall be held on October 20 in 2011 and thereafter on the fourth Thursday of May of each year, commencing in 2012, or on such other day as shall be determined in advance by the Board of Directors.
