WINT- MCG and DR.J have large option events coming their way and they are driving the deal. My guess: they have a buy out offer and they have a partner offer.
Their motivations are driving how this deal shapes up and happens OR drops backward to a re-up with DM. I certainly hope NO re-up, they make the deal at $2/share,min.,plus debt.
Or they smartly do this: offer a partner a mound of shares, pay DM out, then based on achieving certain milestones, that partner has the right to buy the rest of the company--but that last part is kind of tricky so the deal is taking more time than it should for 99% willing and compatible partners.
I think ISC has some product leverage and some big baggage (DM) but they also are working this deal at a very favorable time across the globe. They have to make it now or potentially be victimized by emerging future technology...as Rumsfeld would sort of say: we don't know the unknowns but we know they exist.
