Transition Services Agreement

TRANSITION SERVICES AGREEMENT

This Transition Services Agreement (this “Agreement”) is entered into as of                     , 20    by and among Tropicana St. Louis, LLC, a Delaware limited liability company (“Buyer”), and Pinnacle Entertainment, Inc., a Delaware corporation (“Parent”). Each of Buyer and Parent are sometimes referred to herein individually as a “Party” and collectively as the “Parties.” Capitalized terms not otherwise herein defined shall have the respective meanings ascribed to them in the Purchase Agreement (as defined below).

WHEREAS, Buyer, Parent and Casino Magic, LLC, a Minnesota limited liability company (“Holdco”, together with Parent, “Sellers”), Casino One Corporation, a Mississippi corporation (“Target”), PNK (ES), LLC, a Delaware limited liability company (“ES”), and PNK (ST. LOUIS RE), LLC, a Delaware limited liability company (“RE”), and PNK (STLH), LLC, a Delaware limited liability company (“STLH”, and together with ES, RE and Target, hereafter collectively referred to as the “Companies,” and any one of them individually as a “Company”), are parties to that certain Equity Interest Purchase Agreement, dated as of August 16, 2013, as amended (the “Purchase Agreement”), pursuant to which Sellers have agreed to sell to Buyer, and Buyer has agreed to purchase, all of the issued and outstanding membership interests of the Companies;

WHEREAS, the Companies are engaged in the business of operating (a) that certain casino located in St. Louis, Missouri and commonly known as Lumière Place Casino, (b) that certain hotel located in St. Louis, Missouri and commonly known as HoteLumiere, and (c) that certain hotel located in St. Louis, Missouri and commonly known as the Four Seasons Hotel St. Louis®, (collectively the “Casino”; and including all restaurants, meeting spaces and other amenities associated with such the Casino, collectively, the “Business”);

WHEREAS, Parent currently provides certain operational services to the Business;

WHEREAS, the Purchase Agreement provides that, at Buyer’s election, Parent will provide Buyer with certain reasonably requested transition services after the Closing;

WHEREAS, Buyer desires to continue to operate the Business upon consummation of the transactions contemplated by the Purchase Agreement; and

WHEREAS, at Buyer’s request, Parent will cause Sellers to provide to the Companies, after the Closing, the Services (as defined below), during a transitional period of time as provided below, to enable Buyer to conduct the Business as conducted by Sellers immediately prior to the Closing.

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants, agreements, representations and warranties set forth herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties hereto agree as follows:

ARTICLE 1

TRANSITION SERVICES

Section 1.1     Subject to the terms and conditions of this Agreement, commencing on the Closing Date and until the Initial Termination Date (as defined below) (unless extended or earlier terminated, as applicable, pursuant to ARTICLE 3) with respect to each Service, Parent will cause Sellers to provide to the applicable Company, solely to enable Buyer to conduct the Business as conducted by Sellers immediately prior to the Closing, those services set forth on Exhibit A attached hereto (together with any other services provided by Sellers pursuant to this Agreement, the “Services”) and as are reasonably necessary to transfer administrative support services to Buyer and the Companies. At the request of Buyer, Sellers shall use commercially reasonable efforts to include in the Services the continuation of any goods and services provided to Sellers (if capable of being provided by Sellers) under any Excluded Contract reasonably necessary for the operation of the Business in the same or substantially the same manner as the Business was operated by the Companies as then owned by Sellers immediately prior to the Closing, if Buyer, despite commercially reasonable efforts, has been unable to contract with another Person for those same goods and services upon commercially reasonable terms. In connection with the foregoing, Buyer may, at any time following the commencement of the term of this Agreement, upon written notice to Parent given at least thirty (30) days in advance, request that additional services be added to the Services, so long as such additional services were being provided by Sellers in relation to the Business immediately prior to the Closing and are reasonably necessary for the operation of the Business in the same or substantially the same manner as the Business was operated by the Companies as then owned by Sellers immediately prior to the Closing, and Buyer shall reimburse Parent and Sellers for the Direct Costs (as defined below) of such Services.

Section 1.2     Parent or, at Parent’s direction, Sellers shall be entitled to payment of its Direct Costs for providing such Services. “Direct Costs” means cost not to exceed the cost of labor, material, travel, and other expenditures to the extent the costs are directly incurred to provide the Services. For the avoidance of doubt, “Direct Cost” for Buyer’s use of any of Sellers’ employees’ labor shall not exceed the then-current wage rate for such employee, including benefits. Parent shall endeavor to provide Buyer with an invoice for the Direct Costs each month during the term of this Agreement. The Direct Costs shall be paid within thirty (30) days after the Buyer’s receipt of a statement therefor.

Section 1.3     Parent and Sellers shall be reimbursed by Buyer for all reasonable out-of-pocket business expenses incurred in connection with Parent or Sellers’ performance under this Agreement, including payments to third-party service providers. Parent shall submit itemized requests for reimbursement (or advance payment, as applicable) of such expenditures to Buyer supported by reasonably detailed documentation. Parent shall use commercially reasonable efforts to (i) obtain all necessary licenses, or (ii) modify or amend existing licenses in order for Sellers to obtain all legal authority to provide the Services in accordance with the terms of the Agreement; provided, however, that in no event shall Parent be obligated to provide any compensation or other consideration to cause any third parties to grant any licenses or agree to

- 10 -

modify or amend existing licenses or provide any other accommodation. In the event that Parent or Sellers do not obtain such licenses or modify or amend existing licenses prior to the Closing, Parent shall, and shall cause Sellers to, reasonably cooperate with Buyer in Buyer’s efforts to obtain such licenses for the Services. Parent and Sellers shall be reimbursed by Buyer for all reasonable out-of-pocket business expenses incurred in connection with Parent’s or Sellers’ efforts or cooperation as contemplated by this Section 1.3. Parent shall submit itemized requests for reimbursement (or advance payment, as applicable) of such expenditures to Buyer supported by reasonably detailed documentation. All payments due under this Section 1.3 shall be collectively referred to as “Reimbursements”. All Reimbursements shall be paid within thirty (30) days after Buyer’s receipt of a statement therefor, unless Buyer delivers written notice to Parent that it disputes the amount of the Reimbursements (a “Dispute Notice”). In the event Buyer disputes the amount of any Reimbursement, Buyer and Parent shall negotiate in good faith to agree on the amount of the Reimbursements. If Buyer and Parent have not agreed on the amount of the Reimbursements within thirty (30) days following the date on which Parent received the Dispute Notice, then the Parties shall refer any remaining disputed matter(s) for mediation. If the Parties are not able to resolve such disputed matters by mediation within a reasonable time, not to exceed thirty (30) Business Days, then either Party may bring a suit for damages in accordance with Section 4.2.

Section 1.4     The Parties acknowledge that, during the term of this Agreement, Buyer will be arranging for alternative means of providing the Services to the Companies, and Parent agrees to assist Buyer and the Companies in such efforts and will make available to Buyer and the Companies, or cause Sellers to make available to Buyer and the Companies, any and all non-confidential information, methods of operation, processes or data reasonably necessary to ensure that Buyer can provide services that are substantially similar to the Services in a manner that minimizes any material disruptions to the operations of the Business. Buyer and each Company agree that it will comply with the terms of any license or other contractual obligations imposed by a third party applicable to such Company’s use of the Services or the Business.

Section 1.5     Parent, on one hand, and Buyer, on the other hand, will each nominate one or more representatives, as necessary, to act as the primary contact person(s) with respect to the accomplishment of the transactions contemplated by this Agreement (the “Service Coordinators”). The initial Service Coordinators for each Service are set forth on Exhibit A. Unless Parent and Buyer otherwise agree in writing, all communications relating to the Services shall be directed to the Service Coordinators. Each of the Service Coordinators, and any replacement Service Coordinators, shall be a managerial (or higher) level employee of the Party in question and shall be reasonably qualified to perform, or cause to be performed, the responsibilities of this position.

ARTICLE 2

QUALITY OF TRANSITION SERVICES

Section 2.1     Parent represents and warrants that the Services will be performed in good faith and in substantially the same or a similar manner of performance as such Services were performed immediately prior to the Closing Date (subject to any differences resulting from restrictions on Sellers’ legal authority to provide the Services). IN NO EVENT SHALL

- 11 -

PARENT (OR ANY SELLER) BE DEEMED TO MAKE ANY OTHER REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED (INCLUDING ANY WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, WHICH ARE EXPRESSLY DISCLAIMED), WITH RESPECT TO THE SERVICES OR THE PROVISION THEREOF.

Section 2.2     Parent, Buyer and the Companies agree to hold periodic transition service meetings to ensure that the Services are being adequately performed following the Closing Date. The meetings shall be conducted telephonically unless a Party requests an in-person meeting. The meetings shall occur no less than once per calendar month and shall be scheduled for the first Business Day of each calendar month, commencing the first calendar month following the Effective Date. Notwithstanding the forgoing, if reasonably requested by Buyer upon no less than forty-eight (48) hours’ notice from Buyer, the Parties will hold additional meetings; provided that in no event may Buyer request more than three (3) additional meetings per month. The Parties agree to use the meetings as a first resort and forum to make improvements, or settle disputes, regarding the Services.

Section 2.3     The Services are intended to provide Buyer temporary aid in the transition of the Business. Buyer acknowledges that the provision of the Services is in no way intended as a guarantee of results or the successful operation of the Business.

Section 2.4     Parent shall have the right to hire third-party service providers to provide all or part of any Service hereunder, but only to the extent that such Service was being provided by a third-party service provider prior to the Closing. Parent shall in all cases retain responsibility for the provision to the Companies of Services to be performed by any third-party service providers.

Section 2.5     In no event shall Parent have any liability under any provision of this Agreement except for Parent’s gross negligence or willful misconduct in performing, or not performing, the Services and, in any event, Parent shall not have liability under any provision of this Agreement for any punitive, incidental, consequential, special or indirect damages, including loss of future revenue or income, loss of business reputation or opportunity relating to the breach or alleged breach of this Agreement, or diminution of value or any damages based on any type of multiple, whether based on statute, contract, tort or otherwise, and whether or not arising from the other Party’s sole, joint, or concurrent negligence, strict liability, criminal liability or other fault. Buyer acknowledges that the Services to be provided to it hereunder are subject to, and that its remedies under this Agreement are limited by, the applicable provisions of Section 2.1, including the limitations on representations and warranties with respect to the Services.

ARTICLE 3

TERM AND TERMINATION OF TRANSITION SERVICES

- 12 -

Section 3.2     Termination.    Any Service may be terminated by Buyer, in its sole discretion, at any time during the term of this Agreement upon fifteen (15) days’ prior written notice to Parent.

Section 3.3     Extension.   Buyer will use commercially reasonable efforts to terminate the Services as soon as possible following the Closing Date; provided, however, that if, despite its commercially reasonable efforts, Buyer is unable to secure its own services in substitution for any Service on or before the Initial Termination Date for such Service, then, upon written notice from Buyer to Parent reasonably in advance of the applicable Initial Termination Date to enable Sellers to obtain legal authority to continue providing the Service, if applicable, the term of this Agreement as related to such Service shall be extended for such period as may be requested by Buyer up to an additional three (3) months on the same terms and conditions as set forth in this Agreement, unless terminated sooner pursuant to Section 3.2. The term of this Agreement as related to a Service which has been extended beyond the Initial Term is referenced herein as the “Extended Term”.
