He is also proposing a "bad leaver" clause where founders have to sell all their vested or unvested shares at the lowest value between the nominal and subscription price.
What's "good terms"? If everybody is happy and you are moving on to your next venture considers as good terms? I never heard about something like this (and I drafted a lot of investment agreements) and it doesn't make any sense either. Will they sell all their vested shares if they decide to stop investing or not participating in future rounds?
