[1] During the six months ended June 30, 2022, the Company granted an aggregate of 113,000 RSUs to certain employees at grant date fair values ranging from $20.50 to $28.75 per share, with a vesting period ranging from two to four years.

[2] During the period from August 29, 2019 to November 20, 2020, the Company granted an aggregate of 455,000 RSUs. Such RSU grants shall not vest unless and until the Company has, for any fiscal quarter in which the RSUs are outstanding, (i) gross revenue determined in accordance with the Company’s reviewed or audited financial statements in excess of $12.5 million for such fiscal quarter, and (ii) positive adjusted EBITDA of at least $2.0 million, as determined based on amounts derived from the Company’s reviewed or audited financial statements for such fiscal quarter, subject to the recipient continuing to provide services to the Company either as an employee, director or consultant on the last day of the quarter that the performance criteria are met. Provided the respective performance criteria are met, the RSUs will vest in accordance with the time-based requirements contained in the award agreement over three years. In the event of a change of control, all RSUs which have not vested on the date of such change of control shall immediately vest even if the performance criteria have not been met. As of the respective grant dates, the Company determined that it was probable that such performance criteria would be met and therefore, began to record the related amortization expense on the grant dates. The Company determined that the performance criteria were met as of March 31, 2022. As a result, 177,304 RSUs were included above in "Vested and delivered" and 106,031 RSUs were included above in "Withheld as treasury stock."

[3] On July 30, 2021, the Company granted 120,000 RSUs, subject to performance-based requirements, to one non-executive employee, which was subsequently modified on February 18, 2022, with a fair value of $27.23 per share as of the modification date. Such RSU grants shall not vest unless and until the Company has achieved certain revenue for a portion of its business prior to the achievement date deadline for each performance milestone. No amortization of share-based compensation expense has been recognized for these RSUs, because, as of June 30, 2022, the Company determined that it is not probable that such performance criteria will be met. The 120,000 RSUs were included in "Unvested as of June 30, 2022" with a fair value of $27.23 per share.
