I can't see any benefit for the writer in this agreement and it seems the illustrator is the only one who can gain from it.
I ounce entered into a 'partnership' with a friend. She loaned me one of her characters but didn't expect payment for doing it. I intended to give her extensive credit once the book was published, although I didn't tell her that. We had a few months to enjoy the writing of Turncoat. She contributed the character, ideas for scenes, feedback on the book's development and what I was doing with my own characters. Sadly, she passed away. She gave me permission to keep the character, as did members of her family, although I plan to use him only in Turncoat.
My advice, which you didn't ask for, is that if you're not having fun with a friend as I did in my 'partnership', probably you should get yourself out of it.
