NOTE 9.   SUBSEQUENT EVENTS

In April 2018, we entered into promissory note and warrant purchase agreements (the “2018 Notes” and “2018 Note Warrants”) with certain accredited investors, pursuant to which we issued and sold $7.5 million of senior secured promissory notes and warrants to purchase an aggregate of 6.0 million shares of our common stock.  The 2018 Notes bear interest at 8.5%, are payable May 1, 2019 and are secured by our assets pursuant to the terms of a security agreement.  The 2018 Note Warrants have an exercise price of $2.35 per share and a life of two years.  If the shares underlying the 2018 Note Warrants are not registered for resale on a registration statement within six months, we will issue an additional warrant to each purchaser at the same exercise price for one-half of the shares covered by the initial 2018 Note Warrants.  We may call the warrants at $0.01 per share, if our stock trades above $8.00 per share for 15 consecutive days.
