If you are asking admission offer out of waitlist,
I saw one 'out of waitlist into Brown' at GradCafe few weeks ago.
It was posted, though, that (s)he was waitlisted for financial aid..
I've read at Brown's website they guarantee 5-year financial aid to all incoming Ph.D students.
I think if your friend is admitted but waiting to be funded, (s)he may not to be worried..
