Yosemite Street, Suite 105, Centennial, CO. 80112

On November 10, 2014, Mr. Smith subscribed for, purchased and acquired ownership and control of 4,132,232 special warrants (the “Special Warrants”) of the Company at a price of $0.55 per Special Warrant pursuant to the closing of the private placement (the “Private Placement”) by the Company of an aggregate 19,245,813 Special Warrants at $0.55 per Special Warrant for total gross proceeds of $10,585,197.15. Each Special Warrant will entitle the holder to receive upon exercise or deemed exercise, for no additional consideration, one unit of the Company (a “Unit”).  Each Unit is comprised of one common share of the Company (a “Share”) and one transferable common share purchase warrant (a “Warrant”).  Each Warrant will entitle Mr. Smith to acquire one additional common share (a “Warrant Share”) at a price of $0.65 per Warrant Share until November 10, 2016.  Accordingly, upon conversion of the Special Warrants, 4,132,232 Shares and 4,132,232 Warrants will be issued to Mr. Smith.
