Under the Company’s amended 2015 New Employee Incentive Plan (the “2015 Plan”), awards may be granted to employees who were not previously an employee or director of the Company, or following a bona fide period of non-employment, as a material inducement to entering into employment with the Company. As of June 30, 2021, there were 210,389 shares of common stock remaining and available for future issuances under the 2015 Plan.

On May 17, 2021, the stockholders of the Company approved an amendment and restatement to the Company’s 2020 Stock Incentive Plan (the “2020 Plan”) to increase the total number of shares of common stock reserved for issuance under the 2020 Plan by 1,000,000 shares. The 2020 Plan provides for the award or sale of shares of common stock (including restricted stock), the award of stock units and stock appreciation rights, and the grant of both incentive stock options to purchase common stock. The 2020 Plan provides for the number of shares available for issuance to be increased to the extent that awards granted under the 2020 Plan and the Company’s 2014 Equity Incentive Plan (as replaced by the 2020 Plan) are forfeited or expire (except as

otherwise provided in the 2020 Plan). As of June 30, 2021, there were 599,712 shares remaining and available for future issuances under the 2020 Plan.

Generally, options issued under the 2020 Plan are subject to a one-year, two-year or four-year vesting schedule, with options vesting in equal installments on the monthly anniversary of the grant date and have a contractual term of 10 years.
