The Reorganized Debtors may pursue such Causes of Action, as appropriate, in accordance with the best interests of the Reorganized Debtors.

Unless any Causes of Action against an Entity are expressly waived, relinquished, exculpated, released, compromised, or settled in the Plan or a Bankruptcy Court order, the Reorganized Debtors expressly reserve all Causes of Action, for later adjudication, and, therefore no preclusion doctrine, including the doctrines of res judicata, collateral estoppel, issue preclusion, claim preclusion, estoppel (judicial, equitable, or otherwise), or laches, shall apply to such Causes of Action upon, after, or as a consequence of the Confirmation or Consummation.
