Note 5 – Senior Convertible Notes

At June 30, 2019 and December 31, 2018, we had $230,000 of Senior Convertible Notes outstanding held by Canadian investors that, although qualifying for automatic and mandatory conversion, could not be converted until the Alberta Securities Commission released us from a cease trade order, which predated our merger with HeatWurx, and permitted us to issue common stock units (consisting of shares of our common stock and stock purchase warrants) to these Canadian investors. In June 2019, the Alberta Securities Commission released the cease trade order and assessed us a $10,000 fine, which was expensed. On July 2, 2019, we converted the principal and related accrued interest of $259,830 into 126,741 shares of common stock and 126,741 stock purchase warrants.
