The RSUs vest at such time as the average closing market price of A-Mark common stock over a 30-day period is $15 per share or higher, provided that the Reporting Person remains employed at that time and subject to accelerated vesting in specified circumstances. If not previously vested, the RSUs expire on June 30, 2023. </footnote> |
