This filing is about the recent financing.
Way I read it is:
Unit = 21 Notes + 21 Warrants.
Notes = 17.5 million shares
Warrants = 17.5 million shares
When Note is converted to shares, the holder surrenders collection on the note principal, $25k, and interest ($ depends on how long it is held before converted) of the note and receives 833,334 shares to do with as they please.
When a Warrant is exercised, it is like the lender buying shares for 0.1200 each. This would net the company an additional $100k for each unit.
