(1) The performance-based RSUs granted to our executive officers in 2018 were subject to satisfaction of specified service-based and performance-based conditions. The performance objectives were subject to under- or over- achievement on a sliding scale, with a threshold of 50% of the target number of RSUs and a maximum of 150% of the target RSUs. In March 2020, our Compensation Committee determined actual achievement of the 2018 performance-based RSUs at 100.5%.

(2) The performance-based RSUs granted to our executive officers in 2019 and 2020 were subject to the satisfaction of specified service-based and performance-based conditions over a three-year performance period. Achievement of the revenue and Adjusted EBITDA goals for the 2019 and 2020 performance-based RSUs is based upon the budgets established for each of the years in the three-year performance period. As the Company approves budgets on an annual basis, the performance targets for the 2019 performance-based RSUs related to the 2020 and 2021 revenue and Adjusted EBITDA goals and the performance targets for the 2020 performance-based RSUs related to the 2021 and 2022 revenue and Adjusted EBITDA goals were not considered defined as of the date these awards were awarded by the Compensation Committee. The grant date requirements of ASC 718, Compensation-Stock Compensation, are therefore not met until such approval is obtained. During the nine months ended September 30, 2020, the Company’s Compensation Committee approved the 2020 revenue and Adjusted EBITDA performance targets for the 2019 performance-based RSUs resulting in additional RSUs granted of approximately 36,000 at a grant-date fair

value of $12.41 per share. As of September 30, 2020, 36,000 2019 performance-based RSUs and 178,000 2020 performance-based RSUs have been excluded from RSU shares granted and non-vested as the performance targets have not yet been defined.
