I think they are relatively small. Not zero, but small. You don't bring in a "sell the company" CEO then ask him to operate the company out of a hole.
We could get a price substantially less than the numbers we have tossed around here and it would still be "in the best interest of shareholders" to take the deal. For example, although I think PTX is worth more, we could see an announcement that it has been sold for $5-6 per share. I'd be disappointed, but it if came to that I would vote to accept that offer if management recommended it rather than trying to redirect and stay the course through operating our way to another exit strategy.
I think it highly unlikely that management turns down any solid deal over $5.
I also think it is very likely that Sedor would have bailed by now if he was getting the feeling that they simply were not going to get any interest or only stink bids.
