Following any sales under his trading plan, Mr. Grumbacher will continue to hold a majority of the outstanding voting power of the Company’s common stock and Class A common stock. In addition, based upon current stock holdings, Mr. Grumbacher will continue to be the largest beneficial owner of the Company’s capital stock.
