I am not overly worried about the risk factor section. There's nothing that stands out to me (just went through it again). I don't mean to imply that those sections are never important, just not in this case.
I have been told that there was an agreement in place. My sources could be wrong, but they are usually right. This area of investing is not my expertise, but I rely on very experienced people to get information. The lack of inclusion of the Cognate agreement in the exhibit is beyond me, and you could be right that it was terminated. It would have had to be terminated prior to NWBO having any information regarding the acquisition of Cognate by CRL. I really don't see why that would have happened as I assume that it was advantageous to Cognate for being there during the trial. As with any posts on this board, it is just an opinion of a poster and we are allowed to disagree on subject matters.
