Award of 2019 Performance Bonuses and 2020 Equity Incentive Awards

On March 10, 2020, upon the recommendation of the compensation committee and pursuant to the Company’s 2014 Omnibus Stock Ownership Plan, the Company’s board of directors approved a total of 1,170,000 options to purchase the Company’s common stock as (i) performance bonuses for 2019 performance and (ii) equity-based incentive awards to the Company’s executive officers. Each option award was granted with an exercise price of $2.12 per share, the closing price of the Company’s common stock on the Nasdaq Global Market on March 10, 2020, with the option award vesting in 48 equal monthly installments over a four-year period, subject to such executive officer’s continued service on the applicable vesting date. Additionally, on March 10, 2020, the Company issued 111,000 options to purchase the Company’s common stock to other employees of the Company as equity-based incentive awards. Each option award was granted with an exercise price of $2.12 per share, the closing price of the Company’s common stock on the Nasdaq Global Market on March 10, 2020, with the option award vesting in 48 equal monthly installments over a four-year period, subject to such executive officer’s continued service on the applicable vesting date.

The above awards were in addition to stock option awards issued during the six months ended June 30, 2020 to new employees upon their commencement of employment with the Company.
