According to Robert, he exchanged emails with Dave and he does not see that Dave would not be involved. Robert would go down to meet Dave on a separate manufacturing meeting in Indiana, once he is a bit better. He said that Dave is welcomed to come to the meeting next week.
IMO, it may be some difficult time and tension at the moment. Certain NCND agreement that need both parties to observe.

As of now, there are a lot of things to clear up.
