As of the date hereof, Acacia is purchasing shares from Browne and Schmidt and consequently Acacia owns approximately 51% of the total number of issued and outstanding shares of Common Stock on a fully diluted basis, and Browne and Schmidt each own approximately 9.5% of the total number of issued and outstanding shares of Common Stock on a fully diluted basis. Carl M. Elam and Dale A. Leavy (the "INVENTORS") each owns 525,000 shares of Common Stock representing in the aggregate 14% of the total number of issued and outstanding shares of Common Stock on a fully diluted basis.
