I just ask because it's quite a chunk of change that would be great to have. Murphy's law predicts that as soon as I cancel the session, he gets the money by Friday. ;)

Tell Murphy to take a hike, and he should not be in the equation or you should not be in business!
But I have 2 pieces of writing that I have gotten some help on, and that person has a percentage on it. And they are not my agent, but they helped at a time that I needed it badly.
It's a 2-edged sword, sometimes, and you have to look at it directly and make your call and not look back. And there is always the one that will make it, and you do not gain benefits from it in the future, and you can say that you did not know, or have a good enough sense to make a call on it.
I would think that I would evaluate that person's work and such, and then make a call, so you don't feel like you have to take on something you don't want, and on top of it, something that is just plain wishy-washy, and becomes a waste of time.
I can not tell you what I would do, but I would make sure you take a good look at the work and that person, and then make your call. But it sounds to me that those folks are playing a dangerous game of making sure they can walk away with benefits for nothing, and no one can afford that in this day and age. I'm not saying that you can not afford to do something for free, but maybe, just maybe, there is that one time when you did, and it comes back to ... pat you in the back and then some!
You have to take it as you will and not look back is my guess.
But when it comes to screenplays, yeah, 2 of them already have 10% of it gone. It's peanuts, you know, because when/if they sell it's a quarter, and my investors stand to gain 25K each ... and it's like a lottery ticket. One day, when you least expect it, there it is! Your dream!
