I had a lot of the Feb. 12.5 calls and exercised them. Glad I did. I would have given them up for .45 cents had I sold them at expiration and they'll soon be worth 65-70 cents each on the actual shares I bought. This is a nice percentage return and this stock looks like either a take over candidate ( I have no personal knowledge to support this) or simply a stock with a lot of people wanting to own it. I'm hanging on to my shares.
