During the nine months ended September 30, 2022, the Company granted options to purchase 1.9 million shares of common stock with an exercise price ranging from $4.96 to $8.46 per share, a term of 10 years, and a vesting period of 4 years. The options have an aggregated fair value of $6.6 million that was calculated using the Black-Scholes option-pricing model.

The fair value of the RSUs, $1.8 million, was determined based on the stock price of $5.85 on the date of the grant and is being recognized over three years. The unrecognized compensation expense at September 30, 2022 of $1.7 million is expected to be expensed over 2.9 years.
