If someone makes an offer, there will be a vote. Either the BOD or the shareholders or maybe both, in this case I'd guess shareholders. If the majority of either, I'd probably say substantial majority because if it was a close win either way you might have lawsuits by the losing side to try to stop the sale or no sale, decides to take the deal then you'd probably want to take the deal or else you probably end up holding worthless shares. I believe that's the way it works. I'm sure I'll be corrected if not.
