Subject: what will happen to particles in ergosphere of evaporating b.H.

If the kerr black hole were to evaporate what will happen to the particles 
like photons and protons, that are in the ergosphere but had not reached event 
horizon, will the particles louse their spin or will the particles continue to 
rotate the same way around an empty space or will their motion will continue 
but will be very different?
