The Compensation Committee granted a stock option to purchase 600,000 shares of the Company’s common stock to Daniel R.

Hundley, President of the Company. In addition, the Compensation Committee granted each of the following directors a non-qualified stock option to purchase 10,000 shares of the Company’s common stock: John V. Giovenco, Richard J. Goeglein, Bruce A. Leslie, James L. Martineau, Michael Ornest, Timothy J. Parrott, and Lynn P. Reitnouer.

Each stock option described herein was granted in accordance with the terms of the Company’s 2005 Plan. All such stock options vest ratably over a period of five years from the date of grant and are exercisable at a price of $14.70 per share, the closing price of the Company’s stock on May 3, 2005. Each option must be exercised no later than ten years from the date of grant. Each executive officer or director who has been granted a stock option under the 2005 Plan will enter into a stock option agreement with the Company related to such stock option grant.
