As per my reply to Jroon, apparently Denner is happy wasting time and money, even in the stocks he has been actively involved in.
So it would be a lot smarter for him to take $5 and leave than stick around and fail.
It seems that the deeper you look into Sarissa, the less you want them involved in the stock in the long term. They have a good record of bringing things beneficially to a terminus (buyout) but have a much sketchier record for companies they get involved in but don't close out.
