FURTHER RESOLVED, that there are hereby reserved a total number of shares of Common Stock equal to $20,000 worth of shares (as valued under the foregoing formula) to honor the obligations of the Corporation under the Glesmann Agreement, and that when such shares are issued, they shall be deemed fully paid and non-assessable shares of the Corporation’s Common Stock;
