This program explores the boundaries of the sub rosa plan doctrine in a variety of contexts potentially arising in chapter 11 cases. The focus is on efforts to resolve the relationship of the debtor to all or many of its creditor constituencies and equity-holders that arguably deviate from the priority and procedural schemes of the Bankruptcy Code. Among the areas examined are (1) secured creditor/acquirer carve-out and/or gifting agreements, (2) structured dismissals following § 363 sales, (3) settlements of significant or global controversies, (4) lock-up and plan-support agreements, and (5) significant distribution or settlement arrangements made in the context of DIP financing or asset sales made jointly with nondebtor parties.
