I don't understand what you mean by clear and free?

Sheldon has lots of shares so if he wanted to do that than I think he could still leave his $.35 options as is. I think there are other reasons for Sheldon exercising those options perhaps more along the lines of what Fj stated earlier. But it's great that everyone is trying to find that exact reason for him doing that. It could tell us what to expect for where the share price is going.
