SERVICES. Upon 30 days written request from Hilton, Park Place shall provide to Hilton, to the extent requested in such notice, the types of Corporate Services set forth in Exhibit A. As of the date of this Agreement, Hilton has requested Park Place to provide those services described on Exhibit B. The scope of the services to be provided by Park Place hereunder shall be consistent with the scope of the services being provided by the Gaming Group to the Retained Business Group on the date the Merger Agreement is signed and shall not be expanded unless otherwise agreed to in writing by the parties hereto.

Park Place shall not be held responsible for the performance of such consultant/contractor services and Hilton assumes the risk thereof. 4. COOPERATION. Hilton will provide access to information and its employees necessary for Park Place to provide such Corporate Services. Hilton shall, in a timely manner, take all such actions as may be reasonably necessary or desirable in order to enable or assist Park Place to provide the Corporate Services, including, but not limited to, providing necessary information and specific written authorizations and consents, and Park Place shall be relieved of its obligations hereunder to the extent that Hilton's failure to take any such action renders performance by Park Place unlawful or impracticable. 5. FEES AND PAYMENT. Hilton shall pay Park Place for services requested by and rendered to Hilton hereunder as follows: a. Fees for the Corporate Services for the Initial Term shall be based on the fair value of such services based on an arm's length negotiation between Hilton and Park Place. Fees for work performed by outside consultants/contractors retained by Park Place outside of the ordinary course of business shall be paid directly by Hilton and shall not include any mark-up or margins by Park Place. b. Park Place shall invoice Hilton once each month for the services performed during the prior month, other than services provided by consultants/contractors outside of the ordinary course of business, which services will be invoiced directly to Hilton by such consultants/contractors. Payment for all services hereunder, other than services provided by consultants/contractors outside of the ordinary course of business, shall be made by Hilton to Park Place within 30 days of receipt of invoice for payment (with appropriate supporting documentation for any out-of-pocket expenses). Payment for services performed by consultants/contractors outside of the ordinary course of business shall be made promptly by Hilton following Hilton's receipt of invoices for such services. Any payments not made by Hilton to Park Place when due shall bear interest, computed daily, from the date due to the date of payment based on the annual percentage rate equal to the Prime Rate, as the same may vary from time to time, plus two percentage points. c. If at any time during the term of the Agreement, Hilton moves its office location from 9336 Civic Center Drive, Beverly Hills, California, both the availability of certain services and their associated rates may be subject to change. If any additional services are provided by Park Place, other than as set forth in the Exhibits attached hereto, or if the scope or nature of the Corporate Services provided at any time under this Agreement change materially, the parties hereto will negotiate in good faith to set new fees based on the fair value of providing such additional or revised services. d. Fees for Corporate Services provided after the Initial Term, if any, shall be mutually agreed upon by the parties. 3 e. The parties agree that in the event that any tax or assessment is required to be paid as a result of the provision of services hereunder, other than any income tax (for which the party incurring such expense shall be responsible), Hilton shall be solely responsible for the payment of such tax or assessment. 6. DUTY OF CARE. a. PARK PLACE'S OBLIGATIONS. All services provided and all obligations hereunder shall be administered in accordance with Park Place's standard policies, procedures and practices in effect as of the date hereof and as may be changed from time to time, or as otherwise specified in accordance with the terms hereof. In so doing, Park Place shall exercise the same care and skill as it exercises in performing like services for itself. In the event Park Place changes its policies, procedures or practices, the Corporate Services performed hereunder may be modified by Park Place to meet such revised policies, procedures and practices provided that Park Place gives Hilton prior written notice of such change and a reasonable opportunity for Hilton to adapt its operations to accommodate such changes or to reject such change. Hilton's decision whether or not to accept the proposed change must be made on or before the date Park Place implements such change, which date shall be specified in the notice given to Hilton. Hilton agrees to pay any charges (i) resulting from Park Place's need to maintain different versions of the same systems, procedures, technologies, or services and (ii) resulting from requirements of third party vendors. Notwithstanding anything to the contrary in this Section 6.a., Park Place's liability for the provision of services hereunder shall be strictly limited, as set forth in Section 9. b. HILTON'S OBLIGATIONS. Hilton shall adopt reasonable measures to limit its and Park Place's exposure with respect to any potential losses and damages, including, but not limited to, periodic examination and confirmation of results, provision for identification and correction of errors and omissions, preparation and storage of backup data, virus prevention, security, replacement of lost or mutilated documents, and reconstruction of data. 7.

Each party shall have the right at any time and from time to time to replace any of its Representatives by giving prior notice in writing to the other party setting forth the name of (i) each Representative to be replaced and (ii) the replacement, and certifying that the replacement Representative is authorized to act for the party giving the notice in all matters relating to this Agreement. 4 8.

Park Place and Hilton agree that all information regarding the Corporate Services provided hereunder (the "CONFIDENTIAL INFORMATION"), including, but not limited to, price, methods of operation and software, shall be maintained in confidence and not be released to any third party for any reason whatsoever, excluding such parties' counsel, agents, auditors or lenders. However, a party may release the Confidential Information to a third party upon the prior approval of the other party (such approval not to be unreasonably withheld, conditioned or delayed), upon court order or as such party in good faith believes, based on the advice of counsel, is required by any rules, regulations or laws. Notwithstanding the previous sentence, in the event that a party becomes legally compelled (by deposition, interrogatory, request for documents, subpoena, civil investigative demand or otherwise) to disclose any information, such party shall provide the other with prompt prior written notice of such requirement so that the other party may seek a protective order or other appropriate remedy to minimize disclosure of the Confidential Information. In the event that such protective order or other remedy is not obtained, or the other party approves the disclosure, the disclosing party agrees to furnish only that portion of the Confidential Information which the disclosing party in good faith believes, based on the advice of counsel, is legally required and to exercise reasonable efforts to obtain assurance that confidential treatment will be accorded to such information. Each party shall cease use of all Confidential Information which any party has obtained from the other upon the expiration or earlier termination of this Agreement. The provisions of this Section 8 shall survive the expiration or earlier termination of this Agreement b. Any Hilton information or other information provided by Hilton to Park Place for use with the Corporate Services provided hereunder and identified in writing as confidential shall remain the exclusive and confidential property of Hilton. Park Place shall treat such information as confidential and will not disclose or otherwise make available any Hilton information to any person other than employees, consultants, or auditors of Park Place with a need-to-know or except as required by court order or as such party in good faith believes, based on the advice of counsel, is required by any rules, regulations or laws. Park Place will instruct its employees who have access to the Hilton information to keep the same confidential by using the same care and discretion that Park Place uses with respect to its own confidential property and trade secrets. c. Park Place will continue current security provisions regarding third parties' access to Hilton information. Park Place reserves the right to issue and change regulations and procedures from time to time to improve file security. d.

At Hilton's request, Park Place will provide Hilton, in a standard Park Place format and at Park Place's then standard rates for such format, any and all Hilton information requested. f. Park Place's systems used to perform the Corporate Services provided hereunder are confidential and proprietary to Park Place or third parties. Hilton shall treat these systems and all related procedures as confidential and proprietary to Park Place or its third party vendors and shall be directly bound by and responsible for applicable license and other obligations.
