My guess is that any suitor, based on recent volumes, has already acquired around 7-10 percent of OS shares, minus any warrants and options. The chess game is being played folks. A major can throw this company around like a rag doll. So all you can do is wedge yourself into a corner and tightfist your shares, hoping your cost basis is lower than theirs.
BTW I own SPQ, KWG, NOT, BMK, FNC, and TBM...significant amounts of all.
