There have been no material changes to the terms of our 2018 Equity Incentive Plan (the "2018 Plan"), 2018 Employee Stock Purchase Plan ("2018 ESPP") and 2009 Equity Incentive Plan ("2009 Plan") since the filing of our Annual Report on Form 10-K. Refer to Note 14, Stock-Based Compensation, in our Annual Report on Form 10-K filed with the SEC on April 7, 2022 for more information on our various equity incentive plans.
2018 Equity Incentive Plan
Shares of common stock reserved for issuance under the 2018 Plan also will include any shares of common stock subject to stock options, restricted stock units or similar awards granted under the 2009 Plan, that, on or after the adoption of the 2018 Plan, expire or otherwise terminate without having been exercised in full and shares of common stock issued pursuant to awards granted under the 2009 Plan that are forfeited to or repurchased by us. As of June 30, 2022, the maximum number of shares of common stock that may be added to the 2018 Plan pursuant to the foregoing is 897,229. Not including the maximum number of shares from the 2009 Plan that may be added to the 2018 Plan, the 2018 Plan had 3,582,435 and 762,038 shares of common stock reserved for future issuances as of June 30, 2022 and December 31, 2021, respectively.
Restricted Stock Units
A summary of our restricted stock unit activity under the 2018 Plan for the six months ended June 30, 2022 is set forth below:
Stock Options
During third quarter of 2021, we granted an option to purchase 50,000 shares of our common stock to a non-employee consultant with an exercise price of $1.08 per share. The option vests over one year in twelve equal monthly installments. The non-employee consultant ceased providing services to us during the second quarter of 2022, and, as such, 12,500 shares of this
stock option were forfeited as of such date. As of June 30, 2022, the holder had not exercised the balance of this stock option and this is the only stock option grant outstanding under the 2018 Plan.
2018 Employee Stock Purchase Plan
We use a Black-Scholes option pricing model to determine the fair value of shares to be purchased under the 2018 ESPP. Stock-based compensation expense related to our 2018 ESPP for the three and six months ended June 30, 2022 was not significant. There were 911,245 and 189,215 shares of common stock available for sale and reserved for issuance as of June 30, 2022 and December 31, 2021, respectively.
2009 Equity Incentive Plan
A summary of our option activity under the 2009 Plan and related information is as follows:
For the six months ended June 30, 2022, the aggregate intrinsic value of options exercised was $374 and the total fair value of options vested was $16.
