modified from time to time, the “Intercreditor Agreement”), among Bank of America, N.A., as Credit Agreement Agent and each Other First Priority Lien Obligations Agent from time to time party thereto, each in its capacity as First
Lien Agent, U.S. Bank National Association, as Trustee and each collateral agent for any Future Second Lien Indebtedness from time to time party thereto, each in its capacity as Second Priority Agent (attached hereto as Exhibit A). Capitalized terms
used but not defined herein shall have the meanings assigned in the Intercreditor Agreement. 
 This Joinder and Supplement to
the Intercreditor Agreement (this “Agreement”), dated as of February 20, 2013 (the “Effective Date”), by and among (i) U.S. Bank National Association, as trustee (the “New Trustee”)
pursuant to the indenture, dated as of August 22, 2012 (the “Base Indenture”), by and among Caesars Escrow Corporation (“Escrow Corp.”), Caesars Operating Escrow LLC (together with Escrow Corp., the
“Escrow Issuers”), Caesars Entertainment Corporation (“CEC”), as parent guarantor, and the New Trustee, as supplemented by a supplemental indenture dated as of October 5, 2012 among Caesars Entertainment
Operating Company, Inc. (“CEOC”) and the Trustee (the “Prior Assumption Supplemental Indenture”), as further supplemented by a supplemental indenture dated as of December 13, 2012 among the Escrow Issuers, the Company and
the Trustee (the “Additional Notes Supplemental Indenture,” and together with the Base Indenture and the Prior Assumption Supplemental Indenture, the “Existing Indenture”), and as further supplemented by a supplemental indenture
to be entered into as of the date hereof among CEOC and the Trustee (together with the Existing Indenture, the “New Indenture”), pursuant to which CEOC will assume the obligations of the Escrow Issuers under the Existing Indenture,
(ii) U.S. Bank National Association, as Trustee under the Intercreditor Agreement, (iii) Bank of America, N.A., as Credit Agreement Agent under the Intercreditor Agreement, (iv) U.S. Bank National Association, as a Second Priority
Agent under the Intercreditor Agreement, and (v) any other First Lien Agent and Second Priority Agent from time to time party to the Intercreditor Agreement, has been entered into to record the accession of the New Trustee as an Other First
Priority Lien Obligations Agent under the Intercreditor Agreement on behalf of the holders of the 9% Senior Secured Notes due 2020 (the “New Notes”) issued pursuant to the New Indenture on December 13, 2012. 

The parties to this Agreement hereby agree as follows: 
 A. The New Trustee agrees to become, with immediate effect, a party to and agrees to be bound by the terms of the Intercreditor Agreement as an Other First Priority Lien Obligations Agent, as if it had
originally been party to the Intercreditor Agreement as a First Lien Agent. 

 B. The Obligations under the New Notes, the New Indenture and any other document or
agreement entered into pursuant thereto are designated as Other First Priority Lien Obligations. The Lien on the Common Collateral securing such Other First Priority Lien Obligations shall have priority over and be senior in all respects to all
Liens on the Common Collateral securing any Second Priority Claims on the terms set forth in the Intercreditor Agreement and shall be equal and ratable with all Liens on the Common Collateral securing any other Senior Lender Claims. 

C. The New Trustee confirms that its address for notices pursuant to the Intercreditor Agreement is as follows: 

U.S. Bank National Association 
 EP-MN-WS3C, 60 Livingston Avenue 
 St. Paul, MN 55107-1419 

Telephone: (651) 466-6299 
 Facsimile:  (651) 466-7430 
 Attn: Corporate Trust Services, 

         Raymond S. Haverstock 

D. Each party to this Agreement (other than the New Trustee) confirms the acceptance of the New Trustee as an Other First Priority Lien
Obligations Agent for purposes of the Intercreditor Agreement. 
 E. Except as expressly provided herein, in the Intercreditor
Agreement or in any Other First Priority Lien Obligations Documents, the New Trustee is acting in the capacity of Other First Priority Lien Obligations Agent solely with respect to the Senior Lender Claims owed to the New Trustee and the holders of
the New Notes issued pursuant to the New Indenture. For the avoidance of doubt, the provisions of Article VII of the New Indenture applicable to the New Trustee thereunder shall also apply to the New Trustee acting under or in connection with the
Intercreditor Agreement. 
 F. This Agreement shall be construed in accordance with and governed by the laws of the State of New
York. 
 G. This Agreement may be executed in counterparts, each of which shall constitute an original but all of which when
taken together shall constitute a single contract. Delivery of an executed signature page to this Agreement by facsimile transmission shall be as effective as delivery of a manually signed counterpart of this Agreement.
