Footnotes

F1: Performance Share Units ("PSUs") granted under the MGM Resorts International ("MGM Resorts") Amended and Restated 2005 Omnibus Incentive Plan (the "Plan"). Each PSU represents the right to receive between 0 and 1.6 shares of MGM Resorts common stock depending upon the performance of the common stock from the grant date to the date that is three years after the grant date (the "Vesting Date"), relative to a target price of $25.76 (the "Target Price"). The Target Price is equal to 125% of the average closing price of MGM Resorts common stock over the 60-calendar-day period ending on the grant date. If the ending average stock price is less than 60% of the Target Price (the "Minimum Price"), then no shares will be issued on the Vesting Date. If the ending average stock price is equal to or greater than 160% of the Target Price (the "Maximum Price"), then 1.6 shares will be issued on the Vesting Date per PSU. If the ending average stock price is between the Minimum Price and the Maximum Price, then a number of shares will be issued on the Vesting Date per PSU equal to the ending average stock price divided by the Target Price. For this purpose, the ending average stock price is the average closing price of MGM Resorts common stock over the 60-calendar-day period ending on the Vesting Date.

F2: Restricted Stock Units ("RSUs") granted under the Plan. Each RSU represents the right to receive, following vesting, one share of MGM Resorts common stock. The RSUs are subject to meeting minimum performance criteria set by the Compensation Committee of the Board of Directors of MGM Resorts, during the six-month period ending on June 30, 2016 (the "Measurement Date"). Provided such criteria are met, the RSUs will vest in four equal annual installments commencing on the first anniversary of the grant date. If such criteria are not met, then the RSUs will automatically expire on the Measurement Date without any shares being issued.

F3: Profit Growth Plan Performance Share Units ("Profit Growth PSUs") granted under the MGM Resorts International ("MGM Resorts") Amended and Restated 2005 Omnibus Incentive Plan and the Profit Growth Share Incentive Plan, pursuant to MGM Resorts' Form of Performance Share Units Agreement (Profit Growth Share Incentive Plan). Profit Growth PSUs are forfeited if the Company does not achieve its performance goal pursuant to the Company's Profit Growth Plan as of December 31, 2016. Each Profit Growth PSU represents the right to receive between 0 and 1.6 shares of MGM Resorts common stock depending upon the performance of the common stock from the grant date to the date that is three years after the grant date (the "Performance End Date"), relative to a target price of $25.76 (the "Target Price"). The Target Price is equal to 125% of the average closing price of MGM Resorts common stock over the 60-calendar-day period ending on the grant date. If the ending average stock price is less than 60% of the Target Price (the "Minimum Price"), then no shares will be issued on the Performance End Date. If the ending average stock price is equal to or greater than 160% of the Target Price (the "Maximum Price"), then 1.6 shares will be issued on the Performance End Date per Profit Growth PSU. If the ending average stock price is between the Minimum Price and the Maximum Price, then a number of shares will be issued on the Performance End Date per Profit Growth PSU equal to the ending average stock price divided by the Target Price. For this purpose, the ending average stock price is the average closing price of MGM Resorts common stock over the 60-calendar-day period ending on the Performance End Date. Profit Growth PSUs shall be forfeited in the event that the participant's employment terminates for any reason on or before December 31, 2016, but shall not be subject to forfeiture in the event that the participant's employment terminates for any reason after December 31, 2016, however the Minimum Price on the Performance End Date must still be obtained for any shares to be issued in respect of the Profit Growth PSUs.
