Class A Non Voting Preferred Stock
Dividends Payable Nature	On April 3, 1995, the stockholders ratified a proposal consisting of the creation of a new class of Class A non-voting preferred stock with special dividend rights and the declaration of a stock dividend on the Company's common stock consisting of one share of Class A non-voting preferred stock for every five shares of common stock. The stock dividend was payable to holders of common stock on October 20, 1995. The Class A non-voting preferred stock is entitled to a special dividend equal to 3-1/4% of first $10 million, 4-1/2% of next $20 million and 5-1/2% on amounts in excess of $30 million of the amount of any cash awards or settlements received by the Company in connection with the enforcement of five of the Company's patents in its patent lawsuits, less the revised special dividend payable on the common stock with respect to one of the Company's patents. The Class A non-voting preferred stock participates on an equal per share basis with the common stock in any dividends declared and ranks equally with the common stock on distribution rights, liquidation rights and other rights and preferences (other than the voting rights).
Shares Outstanding	Class A non-voting preferred stock issued pursuant to such stock dividend approximates 313,000 shares.
Votes Per Share	The Class A non-voting preferred stock has no voting rights.
