| F4 | On July 15, 2025, the Company granted Mr. Stinchcomb 2,400,000 restricted stock units (RSUs) with tandem dividend equivalent rights under the 2020 Omnibus Incentive Plan. Each RSU represents the right to receive one share of common stock. The RSUs granted are performance-based, subject to the Company achieving certain stock price or financial performance goals. On August 4, 2025, the Board determined that the Company met the first performance condition of the award by achieving 35% year-over-year revenue growth for the period January 1 through June 30, 2025, compared to the same period in 2024, and thereby triggering the vesting of the first tranche of the Award, or 600,000 RSUs. |
| F5 | All vesting is subject to continued employment on the applicable vesting date and any RSUs not earned during the term of Mr. Stinchcomb's employment agreement ("Agreement") will be cancelled. The dividend equivalents rights entitle Mr. Stinchcomb to payout of dividends accrued on each unvested RSU to the extent such RSUs vest and are distributed under the Agreement. |
