The 1,969,000 shares of the Company's Common Stock and 1,150,000 A Warrants being registered for sale and offered by the Selling Shareholders as more fully described in the Registration Statement are lawfully and validly issued, fully paid and non-assessable securities of the Company. 4. The 1,265,000 shares of the Company's Common Stock issuable upon exercise of the A Warrants shall, upon valid exercise of such Warrants and issuance thereof as more fully described in the Registration Statement, be duly and validly authorized, legally issued, fully paid and non-assessable. 5. The 230,000 shares of the Company's Common Stock issuable upon exercise of a Placement Agent's Warrant shall, upon valid exercise of such Warrant and issuance thereof as more fully described in the Registration Statement, be duly and validly authorized, legally issued, fully paid and non- assessable. 6. The 115,000 A Warrants to be issued upon exercise of the Placement Agent's Warrant shall, upon the valid exercise of such Warrant and issuance thereof as more fully described in the Registration Statement, be duly and validly authorized, legally issued, fully paid and exercisable in accordance with their terms.
