Item 8.01 Other Events.
In the past month, Dr. Ruediger Naumann-Etienne, the Company's Chairman of the Board, and Mr. John R. Hinson, the Company's President and Chief Executive Officer, have each established Rule 10b5-1 sales plans for shares of the Company's common stock. Rule 10b5-1 requires, among other things, that the trading plans be established only at a time when the officer is not aware of material, nonpublic information. The plans specify the term of the plans, which for each officer is 18 months, the numbers of shares to be sold, and the times and prices at which shares may be sold. The shares to be sold will be acquired upon the exercise of a portion of stock options which were granted to each of Dr. Naumann-Etienne and Mr. Hinson from 2000 to 2003. The majority of these options were granted in 2000 and are due to expire in 2010 based on their ten-year life.
If all conditions of the plans are met, the aggregate number of shares that may be sold under the plans would be 180,000 for each of Dr. Naumann-Etienne and Mr. Hinson, which would equal approximately 35% and 29%, respectively, of the aggregate number of shares, including vested and unvested equity awards, each officer holds as of November 12, 2008.
