Each RSU represents a contingent right to receive one share of the common stock. All unvested RSUs will automatically expire upon Reporting Person's termination of service from Issuer. On January 12, 2022, the Reporting Person was granted 33,358 RSU's. 50% of such RSU award vested on January 12, 2023 and the remaining 50% will vest on January 12, 2024. Subject to the Reporting Person remaining a service provider to the Company through and including the second anniversary of the date of the above award, if the aggregate market value of the total number of shares issued pursuant to the award as of such date, together with the aggregate market value of any shares underlying this award that have been sold before such date, is less than the aggregate market value of the total number of shares issuable as of original grant date (in each case, as measured by reference to the closing market prices of the Company's common stock on said dates), then the Reporting Person will receive additional fully vested shares on such second anniversary date with an aggregate market value equal to the difference between the two amounts. Any such additional shares shall be issued pursuant to, and shall be subject to, the terms of the Company's 2015 Stock Option and Incentive Plan and the applicable award agreement thereunder. /s/ Steven G.
