IIRC those $0.15 warrants were exercisable at 15 cents for only the first two years.  If those warrants got extended the exercise price of those warrants is now $0.17. I think the VWAP for 20 days has to exceed $0.17 for these warrants.

After some thought I think I may have this wrong. Sorry. I now doubt that the accelerated expiry 'trigger price' is adjusted according to the higher (post 2 yrs) exercise price.  

If anyone has clarity on these warrant trigger questions please chime in.  If anyone has a list of each warrant still outstanding that would be great to see too.  MoneyK?
