Series B During 1993, the Board established a Series B preferred stock, consisting of 750,000 shares. The Series B preferred stock has preference over the Company's common stock and Series A preferred stock; has no voting rights (absent default in payment of declared dividends); and is entitled to cumulative dividends of $0.01 per share per year, payable if and when declared by the Board of Directors. In the event of dissolution or liquidation of the Company, the preferential amount payable to Series B preferred stockholders is $1.00 per share plus dividends in arrears. No dividends have been declared or paid with respect to the Series B preferred stock.
