Executive shall be granted an option (the "Option") to purchase 1.5% of the Class B Membership Units in the Company ("Class B Membership Units") issued and outstanding as of the date on which the closing of the transactions contemplated by the Purchase and Sale Agreement (the "Transactions"), dated December 24, 2003, by and among the Company, LVH Corporation and Park Place Entertainment Corporation (the "Purchase Agreement") occurs. The Option shall be granted pursuant to the Colony Resorts LVH Acquisitions, LLC 2004 Incentive Plan (the "Incentive Plan"), which shall be established and adopted by the Company in connection with the Transactions. The Option shall be subject to three-year vesting under which Executive may exercise one-third of the Class B Membership Units subject to the Option each year on and after each of the first, second and third anniversaries of the date on which the Option is granted. The Option shall be subject in all respects to the terms of (i) the Incentive Plan, (ii) an individual option agreement to be entered into evidencing the Option (the "Option Agreement"), and (iii) the Holders Agreement to be entered into in connection with the consummation of the transactions contemplated by the Purchase Agreement.
