Can we go for H-1B transfer during cap gap period

[gonimp]

I got H-1b approved. It gonna start from Oct 1 2012. My Stem extension is going to end on July 3rd 2012.

1) What happens if my employer who applied for my H-1B revokes it, or stops running pay stubs during Cap gap.

2) Is there any possibility to transfer my H-1b during cap gap before my employer terminates my job.

3) If my employer terminates my job or stops running payrolls during capgap, Am I eligible for 120 days of unemployment grace period as I had during STEM.

Thanks

Goni
