If settled-in-mediation, then the terms will-be-what-they will-be, whatever that is. Stake in NEWCO or a stock buyout (cash) or you just sell you stock when it pops.
IF mediation fails, and IF equitable disallowance is proven and granted, is there enough money to waterfall to commons and how much? I don't know this answer, someone else might have a clue. I know it will be a lot closer than we are now.
