Since the judge approved the EC, the debtors have no choice but including the EC in negotiations.
After reading docket info from the unsecured creditors, it appears they are working hard to get their money back. They want the Midland Texas assets to be sold to the highest bidder so that they get paid. They don't consider it a sure thing that they will be paid back. They believe selling off the assets offers their best chance.
If the debtors and secured creditors offer up a plan where the current management continues to run the company as it did before (and the judge approves it), I doubt the unsecured creditors get back 100% of their money. The price of oil has the biggest impact on who gets their money back.
