During the three months ended March 31, 2022, the Company granted performance awards in the form of restricted stock units.

If the performance metrics meet the threshold level, approximately 29% of the maximum restricted stock units vest. If the performance metrics for the one-year period are at target, approximately 57% of the maximum restricted stock units vest. If the performance metrics are at the maximum, 100% of the maximum restricted stock units vest. Grantees are eligible to receive a ratable portion of the common stock issuable if the achievement of the performance goals is within the targets previously noted.
