not wanting to start a conspiracy theory but I will anyway.
Is this simply a way for the directors to realise some of their profit?
Peter Nightingale's extra 500k shares bought last month @ 2.61 would have realised a nice quick $370k profit
They would have surely run this merger by their large backers (esp Mac bank), and for the big boys BSG is just small change, a good quick return on a small outlay.
