On January 9, 2015, Caesars Entertainment Corporation (“CEC”), Caesars Entertainment Operating Company, Inc., a majority owned subsidiary of CEC (“CEOC”), and certain holders (the “Consenting Creditors”) of claims in respect of CEOC’s 11.25% senior secured notes due 2017, CEOC’s 8.5% senior secured notes due 2020 and CEOC’s 9% senior secured notes due 2020 (collectively, the “First Lien Notes”) agreed to amend and restate (the “Amendment”) the Amended and Restated Restructuring Support and Forbearance Agreement, dated as of December 31, 2014 (the “RSA”), among CEC, CEOC and the Consenting Creditors, which was previously filed by CEC and CEOC on their Current Reports on Form 8-K, filed with the Securities and Exchange Commission on December 31, 2014. Pursuant to the Amendment, the RSA has been amended to provide that if a Qualified Marketmaker (as defined in the RSA), acting solely in its capacity as such, acquires First Lien Notes or indebtedness under CEOC’s credit facility (“First Lien Bank Debt”) from an entity that is not a Consenting Creditor with respect to such debt (collectively, “Qualified Unrestricted Claims”), such Qualified Marketmaker may transfer such Qualified Unrestricted Claims without the requirement that the transferee execute a Transfer Agreement (as defined in the RSA), provided that any such Qualified Marketmaker will otherwise still be subject to the terms of the RSA with respect to the Qualified Unrestricted Claims pending the completion of any such transfer.
