Probably T/O ann.
If so I'm guessing anywhere between 70c to just over $1??
Previous reports suggest that Cephalon are quite keen to add this to their pipeline.
In any event if Cephalon exercise their options @ 70c for 19% of CXS that would pump in a sig amount of capital and would auger very well for future prospects.
After exercise, I think they will end up with approx 29% of CXS.
