Paul- That is correct. 4 month to 2 year to exercise them...at that point they do no need to sell the stock.

All- i would not be worried too much about the warrants...they simply need to exercise in that timeframe (4M to 2Y)...not required to sell.

Also...it is unlikely any long will be dumping shares in large blocks (when and if they do eventually sell)...selling over many days/weeks via profesisonal trading desk would be the best way to minimize impact. With the volume PTK has now....can be managed. I don't see any insiders (or likely PP holders) selling much any time soon - I can't speak for them of course -my gut.
