Pierre seems to be doing just fine without them, so who knows.

Perhaps releasing a model from an "Exclusive" contract is just their way of avoiding having the model work for another studio in a "right to work state" and then having the thin facade of "Exclusivity" come crumbling down.

Exclusivity only works when people are dumb enough to believe that they can really be held to such contracts. Perhaps Pierre was smart enough to know that there was no way they could hold him to such a contract if he wanted to work somewhere else.
