Hi,
Sorry to hear that your H1-B is currently under revocation process. I am not a legal person, but based on my experience with H1-B system (From past 15 years), you may not approved if you try to transfer the H1-B to different employer because as per the new rules USCIS started adjudication process which will consider all your previous H1-B history before they are going to process your application (Let’s say if someone’s H1-B is under RFE stage from employer A and if they try to transfer the H1-B to employer B then USCIS will ask the person to provide the proper explanation for RFE issued with employer A). In that aspect USCIS will consider the revocation process first and there is a chance that they will deny your transfer process based on that reason.
If your H1-B get denied then you can able to transfer/extend after some cooling period, but revocation is firm and it will close the H1-B record permanently, so you may not able to refer the same record for any future process. If there is no valid H1-B record then your CAP Exempt question is not at all valid.
