ACTC is in a better position without him signed. Sounds completely crazy, but let me explain.
For any potential JV, ACTC can now dangle the carrot of either having Lanza or not. If the potential partner wants just the eyes/AMD, then Lanza isn't part of it. If a partner wants the entire product line and everything in the funnel (Lanza science vault), then the deal has to become a LOT better for ACTC and a LOT more expensive of a buy in for any potential "partner". ACTC is now postured for a "pay to play" type scenario.
