Is this negative or slide? If it is slide, you can still ask the lab to pull half stop, but that's all they can do, and yes you will get 1.5 stops overexposed. If it is negative, you might have better chance as the film latitude is wider, not too sure about this but you might be able to ask the shop to process it as ISO400, or to process as ISO100 then try to correct it during printing?
