Yesterday the link wasn't working but it's back today. It's from right below the point where he discusses a PR labled "SEATTLE, June 2, 2015 /PRNewswire/" :
"What I really want you to take away from looking at the warrant structure is about the Series A warrants. Series A warrants (12,320,000 of them) can't be exercised until November 28th. That's a long time away, and a lot can change until then...
Note that the market took last Friday's dilution of 24Mil shares very well so even if the series A warrants are exercised next week it may be a non-event for the share price.
