Description of settlement payment subject to debtors agreement           On December 29, 2016, the Maxus Entities filed with the Bankruptcy Court their proposed Liquidation Plan under the United States Bankruptcy Code. The Plan foresaw a 130 Settlement Payment under the 2016 Agreement and provided that, if the 2016 Agreement was approved, portions of the 130 Settlement Payment would be deposited into (i) a liquidating trust for distribution to creditors and (ii) an environmental response trust for use in remediation. Moreover, if the Liquidation Plan were approved, the 2016 Agreement with the Maxus Entities would likely be confirmed and the claims against the YPF Entities, including the alter-ego claims, would be settled and released in exchange for the 130 Settlement Payment.
