The awards may be in the form of incentive stock options, nonqualified stock options, restricted stock, restricted stock units and performance awards. The 2014 Plan is effective through March 31, 2024. As of December 31, 2020, there are 236,583 shares which remain to be granted under the 2014 Plan.
