Filing H1B

Question details

I am working in Company A with L1 status. I filed for an H1 (FY-2010) with Company B and got it approved. Now Company A as of date wants to file for my H1 (FY-2010).
My questions are:
a) Can the already approved H1 get cancelled because of A's application?
b) Can I loose both H1's (A and B both cancelled)
c) Is there any way to retain at least one (A or B)?

ANSWER

You do not "lose" an existing H-1 by filing of a new one.
