H1 Case picked in lottery , can company withdraw my petition and can it be used by another?


I am working for in India for an employer which has a client in US . My employer filed my H1 and is currently in lottery picked status (case was received). Recently my employer wants me to sign a service agreement for H1 whose terms and condition I do not agree to . Hence I have decided to move on . My employer wants to withdraw my application .

Question1: Can an employer do so ? Will he get the amount refunded?

Question2: Can a new employer file my petition and use the cap . If yes till what duration it will be applicable
