We provide compensation to our non-employee directors in the form of cash and stock-based compensation. During 2020, prior to the consummation of the Spin-Off, we paid Dr. Link an annual cash retainer of $100,000, we paid Mr. McLaughlin an annual cash retainer of $50,000, and we paid each of our other non-employee directors an annual cash retainer of $36,000. We have reimbursed, and will continue to reimburse, our non-employee directors for their actual out-of-pocket costs and expenses incurred in connection with attending board meetings.
In July 2020, Drs. Lindstrom and Link and Mr. Winer were granted 160,636, 400,787 and 20,079 shares of restricted stock, respectively, under our 2020 Plan, with “target percentages” under such awards of 1.6%, 4.0% and 0.2%, respectively (the “July 2020 Director Awards”). The July 2020 Director Awards are subject to the same terms and conditions as the July 2020 Awards granted to our named executive officers and described above under “Executive Compensation – Narrative Disclosure to Compensation Tables – Equity Base Incentive Awards.” In addition, restricted stock will vest on an accelerated basis in the event of a change in control of the Company or a director’s death or disability.
At the time of the Spin-Off, our board of directors waived the clawback provision and none of the July 2020 Director Awards originally granted to the directors was forfeited in connection with the Spin-Off. The number of restricted stock awards retained by our directors were in the following amounts: Dr. Lindstrom, 1,408 shares; and Dr. Link, 2,717 shares. In addition, our board of directors determined that Mr. Winer’s holdings at the time of the Spin-Off were below his target percentage of 0.2% and determined to award him an additional restricted stock award of 51 shares in October 2020, which additional award had the same terms and conditions as his July 2020 Director Award.
On December 7, 2020, our board of directors approved awards of restricted stock to each of Drs. Lindstrom and Link and Mr. Winer in connection with an amendment to their July 2020 Director Awards, which modified and extended the vesting schedule to provide for quarterly vesting of these grants rather than three cliff vesting dates as originally issued. The board of directors approved amendments to each such director’s July 2020 Director Award to amend and extend the vesting schedule applicable to such July 2020 Director Award. In order to comply with tax laws and to recognize the director’s agreement to an extension of the vesting schedule of the July 2020 Director Awards, each director was issued an additional restricted stock award, which represented 20% of the total number of shares subject to his July 2020 Director Award, as follows: Dr. Lindstrom, 32,127 shares of restricted stock; Dr. Link, 80,157 shares of restricted stock; and Mr. Winer, 4,026 shares of restricted stock. The newly-awarded restricted stock will vest on the same amended vesting schedules applicable to the amended July 2020 Director Award, which amended vesting schedules provide for vesting in quarterly installments over a three-year period following the amendment date, subject to continued service through the vesting date. In addition, consistent with the terms of the July 2020 Director Awards, the restricted stock will vest on an accelerated basis in the event of a change in control of the Company or a director’s death or disability. The new restricted stock awards were granted pursuant to the 2020 Plan.
In connection with the Spin-Off, we adopted a non-employee director compensation program that provides for annual retainer fees and/or long-term equity awards for our non-employee directors. Under the non-employee director compensation program, each non-employee director receives an annual retainer of $50,000, with the chairperson receiving an annual retainer of $75,000. Non-employee directors serving as the chairs of the audit, compensation and nominating and corporate governance committees receive additional annual retainers of $15,000, $10,000 and $9,000, respectively. Non-employee directors serving as members of the audit, compensation and nominating and corporate governance committees receive additional annual retainers of $7,500, $5,000 and $4,500, respectively.
Non-employee directors who are newly elected or appointed to our board of directors will receive initial stock option awards having a value of $200,000, calculated based on the Black-Scholes value on the grant date, vesting over three years with one-third of such options vesting on the first anniversary of the date of such election or appointment to the board of directors and the remainder vesting in equal monthly installments over the remaining two years thereafter. On the date of each annual meeting of our stockholders following the Spin-Off, each non-employee director will receive an annual stock option award having a value of $100,000, calculated based on the Black-Scholes value on the grant date, which annual awards will vest in equal monthly installments over 12 months following the grant date. Additionally, equity awards granted to our non-employee directors will vest upon a change in control of our company or upon a director’s death or disability.
Compensation under our non-employee director compensation policy is subject to the annual limits on non-employee director compensation set forth in the 2020 Plan. Our board of directors or its authorized committee may modify the non-employee director compensation program from time to time in the exercise of its business judgment, taking into
