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 MIP 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 MIP 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.
