Japan's Astellas Pharma will buy OSI Pharmaceuticals (OSIP) for $4B in cash, ending a months-long battle between the two firms. The $57.50/share offer is a 55% premium to OSI's closing price before Astellas made its first offer, but is below OSI's recent $59.80 close. (PR) (previously: I, II, III, IV)
