H4 EAD eligibility

[Purnima5458 0]

H1B : 12/12/2020
I140 :  Approved ; more than 180 days
H4 EAD : 12/12/2020

My spouse who hold H1B is got an offer from another company and planning to transfer his H1B soon. 
I have question on - 
  1. What will happen to H4 EAD : Will I be eligible to get extension on spouse previous employer I-140 approval?
  2. What happened if his old employer revoke I-140, shall I get still EAD extension? 

Please help ! 

Thanks
