Options to directors, officers, consultants and employees
The Company maintains, as adopted by the board of directors, the 2019 Stock Incentive Plan as well as previous years plans (the “Plans”) providing for the issuance of equity based awards to employees, officers, directors or consultants of the Company. Non-qualified stock options granted under the plans may only be granted with an exercise price equal to the fair market value of the Company’s common stock on the date of grant. Awards under the plans may be either vested or unvested options.
In addition to the Plans, the Company has granted, on various dates, stock options to directors, officers, consultants and employees to purchase common stock of the Company. The terms, exercise prices and vesting of these awards vary.
The following table summarizes option activity for directors, officers, consultants and employees:
