I agree with that price range (probably the lower end due to the dilutions).
I think $8-$10 is more likely IMO. (if rida is successful).
If Rida shows good results in Endo as well, your range is what I would be looking for.
Much higher if there are some really positive developments on '534.
If Rida is a success, I would be really surprised if we didn't see an offer from someone. I don't know why Merck WOULD'NT want '113 and '534 as well as '573.
