Note 5 – Senior Convertible Notes

At March 31, 2019 and December 31, 2018, we had $230,000 of Senior Convertible Notes outstanding held by Canadian individuals that cannot be converted until the Alberta Securities Commission permits the issuance of our common stock units (consisting of shares of our common stock and stock purchase warrants) to these Canadian holders. If the Alberta Securities Commission does not allow us to convert this debt into common stock units, we will be required to repay the principal and related accrued interest of approximately $255,000.
