Restricted Stock Units ("RSUs") granted under the MGM Resorts International (the "Company") Amended and Restated 2005 Omnibus Incentive Plan (the "Plan"). On April 2, 2020, the Reporting Person voluntarily reduced 100% of her cash compensation (less amounts she had previously elected to defer pursuant to the Company's Amended and Restated Deferred Compensation Plan for Non-Employee Directors) for the remainder of 2020 in exchange for a grant of an equivalent value of RSUs. Such RSUs will vest in full on December 31, 2020. Should the Reporting Person cease serving on the Company's board of directors for any reason prior to December 31, 2020, the RSUs shall vest on a pro-rata basis. Dividend equivalent rights accrue with respect to these RSUs when and as dividends are paid on the Company's common stock and vest on the same dates and in the same relative proportions as the RSUs on which they accrue. RSUs granted under the Plan. Each RSU represents the right to receive, following vesting, one share of Company common stock. Any fractional shares are paid in cash upon settlement. The RSUs will vest upon the earlier of (i) May 7, 2021 or (ii) the date of the Company's next annual meeting of stockholders, in each case subject to the terms of the Plan and applicable award agreement. /s/ Jessica Cunningham, Attorney-In-Fact 2020-12-17
