Stock Awards.
Our 2019 Plan provides for the grant of incentive stock options, or ISOs, within the meaning
of Section 422 of the Code, to employees, including employees of any parent or subsidiary, and for the grant of
nonstatutory stock options, or NSOs, stock appreciation rights, restricted stock awards, restricted stock unit
awards, performance stock awards, performance cash awards and other forms of stock awards to employees,
directors and consultants, including employees and consultants of our affiliates.
Authorized Shares.
Initially, the maximum number of shares of our common stock that may be issued under
our 2019 Plan is 4,530,000 shares, which is the sum of (1) 1,618,813 new shares,
plus
(2) the number of shares
(not to exceed 2,911,187 shares) (i) that remain available for the issuance of awards under the 2016 Plan at the
time our 2019 Plan became effective, and (ii) any shares subject to outstanding stock options or other stock
awards that were granted under the 2016 Plan that (A) terminate or expire prior to exercise or settlement; (B) are
forfeited because of the failure to vest; or (C) are reacquired or withheld (or not issued) to satisfy a tax
withholding obligation or the purchase or exercise price. In addition, the number of shares of our common stock
reserved for issuance under our 2019 Plan will automatically increase on January 1 of each calendar year,
starting on January 1, 2020 through January 1, 2029, in an amount equal to 5% of the total number of shares of
our capital stock outstanding on the last day of the calendar month before the date of each automatic increase, or
a lesser number of shares determined by our board of directors. The maximum number of shares of our common
stock that may be issued on the exercise of ISOs under our 2019 Plan is 13,000,000 shares.
Share Reserve.
As of December 31, 2021, 398,744 shares of our common stock were reserved for issuance
under the 2019 Plan, covering both the 2019 Plan and the 2016 Plan. Following the effects of the 2019 Plan’s
evergreen provisions, 1,310,776 shares of our common stock were reserved for issuance under the 2019 Plan on
January 1, 2022. As of December 31, 2021, Options to purchase 2,818,570 shares of common stock, at exercise
prices ranging from $9.44 to $44.02 per share, or a weighted-average exercise price of $19.80 per share, were
outstanding under the 2019 Plan. As of December 31, 2021, Options to purchase 1,886,318 shares of common
stock, at exercise prices ranging from $1.00 to $4.70 per share, or a weighted-average exercise price of $3.49 per
share, were outstanding under the 2016 Plan.
Shares subject to stock awards granted under our 2019 Plan that expire or terminate without being exercised in full or that are paid out in cash rather than in shares do not reduce the number of shares available for issuance under our 2019 Plan. If any shares of common stock issued pursuant to a stock award are forfeited back to or repurchased or reacquired by us for any reason, the shares that are forfeited or repurchased or reacquired will revert to and again become available for issuance under the 2019 Plan. Any shares reacquired in satisfaction of tax withholding obligations or as consideration for the exercise or purchase price of a stock award will again become available for issuance under the 2019 Plan.
The maximum number of shares of common stock subject to stock awards granted under the 2019 Plan or otherwise during any one calendar year to any non-employee director, taken together with any cash fees paid by us to such non-employee director during such calendar year for service on the board of directors, will not exceed $750,000 in total value (calculating the value of any such stock awards based on the grant date fair value of such stock awards for financial reporting purposes), or, with respect to the calendar year in which a non-employee director is first appointed or elected to our board of directors, $1,100,000.
Plan Administration.
The compensation committee of our board of directors has generally administered the
2019 Plan and is referred to as the “plan administrator” herein. The compensation committee of our board of
directors may also delegate to one or more of our officers the authority to (1) designate employees (other than
officers) to receive specified stock awards and (2) determine the number of shares subject to such stock awards.
Under our 2019 Plan, our board of directors has the authority to determine award recipients, grant dates, the
numbers and types of stock awards to be granted, the applicable fair market value, and the provisions of each
stock award, including the period of exercisability and the vesting schedule applicable to a stock award.
Under the 2019 Plan, the board of directors also generally has the authority to effect, with the consent of any adversely affected participant, (1) the reduction of the exercise, purchase, or strike price of any outstanding award; (2) the cancellation of any outstanding award and the grant in substitution therefore of other awards, cash, or other consideration; or (3) any other action that is treated as a repricing under U.S. generally accepted accounting principles, or U.S. GAAP.
Stock Options.
ISOs and NSOs are granted under stock option agreements adopted by the plan administrator.
The plan administrator determines the exercise price for stock options, within the terms and conditions of the
