The total value (nto including a couple of $2 mill amounts for milestones) was $18.2 when NSTK sold the rights. I really stopped following it after that but I thought it may have been resold after that to another company.
After a bit of digging, this link shows the $54 mill sale which Chas is referring to (probably). Some of that total dolllar amount is tied up in a facility.
