Thanks for posting....I'd been checking almost daily since the last burst of activity but today was busy so I hadn't looked.  

So he converted 37,500 options at 75 cents for a cost of $28,125 then sold 11,800 in two blocks at $2.27 and $2.28 USD....which is about $2.95 CAD...meaning the sale brought in about $34,810 CAD.  

So the good Dr nets a profit of about $6,685 minus trading costs and still has 25,700 shares left over.  

Verify my math but that's how I work it out...
