Item 1.01 Entry into Material Definitive Agreement.

On June 20, 2016, Caesars Entertainment Corporation (“CEC”) and Caesars Entertainment Operating Company, Inc., a majority owned subsidiary of CEC (“CEOC” and, with its debtor subsidiaries, the “Debtors” and, together with CEC, the “Caesars Parties”), and certain beneficial holders (the “First Lien Bank Lenders”) of the claims under the first lien bank debt (the “First Lien Bank Debt” and, the claims with respect thereto, the “First Lien Bank Claims”) incurred by CEOC pursuant to that certain Third Amended and Restated Credit Agreement (the “Credit Agreement”), dated as of July 25, 2014, by and among CEC, CEOC, the lenders party thereto and Credit Suisse AG, Cayman Islands Branch, as administrative agent, agreed to amend (the “Amendment”) the Restructuring Support and Forbearance Agreement, dated as of August 21, 2015 (the “Bank RSA”), among CEC, CEOC and the Consenting Bank Creditors (as defined in the Amendment), with respect to the restructuring of CEOC’s indebtedness (the “Restructuring”). The Amendment will go effective when it is signed by Consenting Bank Creditors holding greater than two-thirds of the aggregate amount of all First Lien Bank Claims held by Consenting Bank Creditors who executed the Bank RSA (the “Requisite Consenting Bank Creditors”). All capitalized terms not defined in this description of the Amendment have the meanings ascribed to such terms in the Amendment.

Pursuant to the Amendment, the Bank RSA has been amended to provide, among other things, the following:

Agreement to Support Plans

Each Restructuring Support Party (as defined in the Amendment) has agreed to support and not hinder the completion of (i) the Restructuring and all transactions contemplated under the Debtor’s Second Amended Joint Plan of Reorganization filed on June 15, 2016 through which the Restructuring will be effected (the “CEOC Plan”) and (ii) if applicable, a chapter 11 plan of reorganization for CEC through which the Restructuring may be effected (the “CEC Plan” and, together with the CEOC Plan, the “Plans”), in each case, pursuant to the terms of the Amendment. In addition, each Restructuring Support Party has agreed to vote in favor of the Plans when properly solicited to do so under the Bankruptcy Code.

Judicial Order Authorizing Cash Payment

The Debtors have agreed to, among other things, within thirty days of the effective date of the Amendment (the “Agreement Effective Date”), file and prosecute a motion for, and use commercially reasonable efforts to obtain, an order of the Bankruptcy Court (as defined in the Amendment) authorizing the Debtors to pay the holders of the First Lien Bank Claims $300.0 million in cash as soon as practicable. Such amounts paid will reduce dollar for dollar the $705.0 million in cash to be received under the CEOC Plan by the holders of the First Lien Bank Claims on the date on which all conditions precedent to the effectiveness of the Plans have been satisfied or are expressly waived (the “Effective Date”).

MFN Restructuring Support Agreement

The Caesars Parties have agreed to refrain from entering into any other agreement, including a restructuring support agreement, with any creditor, committee or group of creditors or official committee of creditors (except for the Official Committee of Unsecured Creditors (as defined in the Amendment)) in connection with the potential restructuring of the Caesars Parties’ indebtedness that includes terms more favorable than the terms set forth in the Amendment (such agreement, an “MFN Restructuring Support Agreement”). Each Caesars Party has agreed that if it enters into an MFN Restructuring Support Agreement in violation of the terms of the Amendment, the Amendment will automatically be amended to the extent necessary to include such more favorable terms set forth in such MFN Restructuring Support Agreement.

Additional Covenants of CEC

If and to the extent that (i) the Effective Date has not occurred by January 1, 2017 and (ii) the holders of Second Lien Notes Claims vote as a class to accept the CEOC Plan, CEC has agreed to provide, by paying on the Effective Date an amount equal to $10.0 million per month during the period commencing on January 1, 2017 and ending on the earlier of the Effective Date and June 30, 2017 (with such monthly payment earned on the first day of each month during the period), and which is payable on account of the principal and accrued interest on the First Lien Bank Claims in cash or New CEC Common Equity (the “Supplemental Bank Creditor Distribution”) to the Debtors or to the Administrative Agent, in either case as a distribution for the benefit of the holders of First Lien Bank Claims, to the holders of First Lien Bank Claims, their pro rata share of the Supplemental Bank Creditor Distribution.

CEC has also agreed that, if and to the extent that the Additional CEC Consideration (as defined in the June 6, 2016 version of the CEOC Plan) is increased, CEC will increase the amount of the Supplemental Bank Creditor Distribution by a percentage amount equal to the same percentage amount by which the Additional CEC Consideration has been increased. Furthermore, if and to the extent that the consideration being received by the holders of claims in respect of indebtedness incurred by the Debtors pursuant to first lien indentures (such indebtedness, the “First Lien Bonds,” and, the claims with respect thereto, the “First Lien Bond Claims”) is increased as compared to the treatment provided to the holders of First Lien Bond Claims pursuant to the June 6 CEOC Plan (as defined in the Amendment), CEC has agreed to increase the consideration being received by the holders of First Lien Bank Claims by the same amount of consideration and subject to the same terms of any such increase.

In addition, CEC has agreed to pay on the Effective Date the RSA Forbearance Fee (as defined in the CEOC Plan) to certain First Lien Bank Lenders on the terms and conditions set forth in the Amendment on account of such lenders’ Supplemental RSA Bonds (as defined in the Amendment). However, CEC will only be liable for $3.0 million in the aggregate in respect of any RSA Forbearance Fees on account of Supplemental RSA Bonds paid under the Amendment to any Consenting Bank Creditors.

The foregoing description of the Amendment does not purport to be complete and is qualified in its entirety by reference to the Amendment and its exhibits, which is filed as Exhibit 10.1 hereto and incorporated herein by reference.

Important Additional Information

On December 21, 2014, CEC and Caesars Acquisition Company (“CAC”) entered into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which, among other things, CAC will merge with and into CEC, with CEC as the surviving company (the “Merger”). In connection with the Merger, CEC and CAC will file with the Securities and Exchange Commission (the “SEC”) a Registration Statement on Form S-4 that will include a joint information statement/prospectus, as well as other relevant documents concerning the proposed transaction. Stockholders are urged to read the Registration Statement and joint information statement/prospectus regarding the Merger when it becomes available and any other relevant documents filed with the SEC, as well as any amendments or supplements to those documents, because they will contain important information.
