Cash compensation is out of the question. The start-up needs it/will need it and will create more value out of it than Charlie could. 2% goes to Charlie if he is willing to continue to support his friends as an "advisor" and promises to bury the hatchet. 1% goes to Charlie if he wants no part of it, but promises to bury the hatchet and buys beer. 0% goes to Charlie if he's being a douche bag about the whole thing.
