The Company's authorized capital consists of Sixty Million (60,000,000) shares of Common Stock having a par value of $.0005 each, and forty million (40,000,000) shares of $.10 par value Preferred Stock. 3. The 800,000 shares of the Company's common stock issued pursuant to the Hayde Agreement and the MVI Agreement (the "Agreements") and which Hayde and MVI propose to sell, were duly and validly authorized, legally issued, fully paid and nonassessable.
