I listened to the meeting again and what is very disturbing is how he justifies charging NNVC (though he never mentions the cost +30%) by saying:
"many such arrangements have milestone payments, royalty payments..., but we decided not to do that, i'm just covering my butt, i don't want to take losses for work being done for NNVC"
Covering costs is covering your butt. Taking a 30% mark up is using it as an ATM.
Yeah, it's hard to take a milestone payment without reaching a milestone. They clearly knew that wouldn't work so they didn't go that route. Hence the ATM strategy.
So Dr. Diwan is covering his butt so he doesn't take losses when he fails to get stuff done (like tox) while working for NNVC. I sure wish investors could cover their butts in this way.
