Each Unit is comprised of: (A) one (1) common share of the Company (each, a " Common Share "); and (B) one-half of one (1/2) common share purchase warrant (each, whole warrant, a " Warrant "). Each Warrant entitles the holder thereof to acquire one (1) Common Share at a price of $0.18 for a period of three (3) years commencing 60 days after the Closing Date (as hereinafter defined); and (ii) up to 2,333,333 units of the company (each, a " FT Unit ") at a price of $0.15 per FT Unit for gross proceeds of up to approximately $350,000.
