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. On exercise by Mr. Smith of all Warrants issued pursuant to the exercise of his Special Warrants, a further 4,132,232 Warrant Shares will be issued to Mr. Smith.

In the event that the Liquidity Event does not occur within 75 days of the closing date of Private Placement, each unexercised Special Warrant will thereafter entitle the holder to receive, at no additional consideration, 1.10 Units (instead of one Unit). Unless qualified by a final short form prospectus, the securities issued under the Private Placement are subject to a four-month hold period that expires March 11, 2015, in addition to any resale restrictions imposed on Special Warrants subscribed for by United States residents under United States securities laws.

All unexercised Special Warrants will be deemed to be exercised on the earlier of (i) the date which on March 11, 2015, and (ii) the 3rd business day after the occurrence of a Liquidity Event.

In addition, Mr. Smith holds 2,500,000 incentive stock options, each entitling him to acquire one Share.

Assuming exercise of all Special Warrants issued under the Private Placement, including those issued to Mr. Smith, Mr. Smith will own and control 15,421,715 Shares of the Company, or approximately 12.04% of the then 143,158,529 Shares which would be issued and outstanding.

On exercise of the Warrants that will be issued to Mr. Smith on exercise of his Special Warrants but not assuming the exercise of all Warrants issued pursuant to the Private Placement, Mr. Smith would own and control 19,553,947 Shares of the Company, or approximately 14.79% of the then 132,177,180 Shares which would be issued and outstanding.

Mr. Smith may increase or decrease his ownership interest in securities of the Company depending on, among other factors, market conditions. Mr. Smith has no present intention to change his holdings of securities of the Company.
