Class A Non Voting Preferred 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.
