When backing somebody should bonuses/rakeback/FPPs be included?

[Gotmilk]

OK first off, the obvious answer to this question is that it should be discussed ahead of time. The situation is, however, that I backed somebody to play live cash games and they chose to deposit the money online and play instead of going to the casino. I don't really have a problem with this as they are a winning player either way, but it did create a question:

When calculating the total win should rakeback/bonuses/FPPs be included into the total win?

He proposes that he was playing online at lower limits for rakeback already, and that the deal was made in order to allow him to play higher limits than he was already playing, not to keep him in action. He thinks that rakeback and bonuses should be contributed towards repaying any loss incurred, but that as long he breaks even or wins the bonuses and rakeback should be his to keep.

I believe that by backing him, I took 100% of the risk, and there for I should get an equal share of the profit. For example, if I backed him to play 20 hours at some live casino, and that qualified him for a freeroll which he won, I'd want a piece of that too as it was my backing him that earned him the freeroll entry.

And once again, I understand that these are all terms that are negotiable and should be agreed upon ahead of time. I'm just looking for what people think the "default" should be if it wasn't agreed upon ahead of time. And as we are friends, I'd like answers to be what you feel is the fairest to both parties, not who would win in front of a judge.

Thanks guys!
