The RSUs vest in three equal installments on each of the first three anniversaries of the grant date; provided, however, that the vesting of 50% of these RSUs is subject to the additional condition that the publicly-traded stock price for the issuer's common stock reaches a 30-day average trading price equal to or above $7.52 per share during the first three years following the grant date. Should the publicly-traded stock price for the issuer's common stock reach a 30-day average trading price at or above $7.52 per share at any time during such three year period, this pricing condition will be satisfied and will terminate. Each RSU represents a contingent right to receive one share of the issuer's common stock. /s/ Craig E. Hunsaker 2020-04-24
