Item 1.01 Entry into a Material Definitive Agreement.

On June 17, 2014, Caesars Entertainment Operating Company, Inc. (“CEOC”) announced that its wholly owned subsidiary, Caesars Operating Escrow LLC (the “Escrow Borrower”), an unrestricted subsidiary under CEOC’s debt agreements, closed on $1,750 million of new term loans (the “B-7 Term Loan”) pursuant to an Incremental Facility Amendment and Term B-7 Agreement, dated as of June 11, 2014, among the Escrow Borrower, Caesars Entertainment Corporation (“CEC”), the lenders party thereto, the Administrative Agent (as defined below), Credit Suisse AG, Cayman Islands Branch, as Escrow Administrative Agent (the “Escrow Administrative Agent”), and the other parties thereto (the “Term B-7 Agreement”). The Escrow Borrower deposited the net proceeds of the B-7 Term Loan into a segregated escrow account and those funds shall remain in such account until the date that certain escrow conditions are satisfied. The funds held in the escrow account will be released to CEOC upon delivery by the Escrow Borrower to the Escrow Administrative Agent of an officer’s certificate certifying that, prior to or concurrently with the release of funds from the escrow account, the relevant escrow release conditions have been satisfied (the “Escrow Release Date”). The escrow conditions with respect to the initial $1,450 million of B-7 Term Loans to be released and with respect to the additional $300 million of B-7 Term Loans to be subsequently released include, among others, the receipt of all required regulatory approvals and, with respect to the subsequent release, the effectiveness of the amendment to the Credit Facilities referred to in CEOC’s Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on May 6, 2014. Upon the Escrow Release Date, the B-7 Term Loans will be assumed by CEOC and will become incremental term loans governed by and incorporated into CEOC’s Second Amended and Restated Credit Agreement, dated as of March 1, 2012 (the “Credit Facilities”), among CEOC, as borrower, CEC, the lenders from time to time party thereto and Bank of America, N.A., as administrative agent and collateral agreement (the “Administrative Agent”).

The B-7 Term Loan has a maturity of January 28, 2018; provided that if the aggregate principal amount of CEOC’s 11.25% Senior Secured Notes due 2017 outstanding on April 14, 2017 exceeds $250.0 million, the B-7 Term Loan will mature on April 14, 2017.

The Escrow Borrower granted to the Escrow Administrative Agent, for the benefit of the lenders of the B-7 Term Loan, a first priority security interest in the escrow account.

Item 2.03 Creation of a Direct Financial Obligation.

The information set forth under Item 1.01 is incorporated by reference herein into this Item 2.03.

On June 17, 2014, CEC issued a press release announcing that its subsidiary, CEOC, has amended its previously announced cash tender offers for any and all of its 5.625% Senior Notes due 2015 (the “5.625% Notes”) and any and all of its 10.00% Second-Priority Senior Secured Notes due 2015 (the “10.00% Notes”), subject to financing and other conditions.
