Executive Severance Plan

On February 7, 2025, the compensation committee of our board of directors (the Compensation Committee) approved and adopted an Executive Severance Plan (the Severance Plan), pursuant to which executive officers are eligible to participate, including Kyle W. Gano, Ph.D., our President and Chief Executive Officer, Matthew C. Abernethy, our Chief Financial Officer, Eric Benevich, our Chief Commercial Officer, Jude Onyia, Ph.D., our Chief Scientific Officer, and Eiry W. Roberts, M.D., our Chief Medical Officer (each, a Covered Employee, and collectively, the Covered Employees). Pursuant to the Severance Plan, the Covered Employees are eligible to receive the severance benefits described below, contingent upon the respective Covered Employee’s execution of a general release of claims in favor of the Company as further described in the Severance Plan. The severance benefits provided pursuant to the Severance Plan supersede any severance benefits to which the Covered Employees were previously entitled, including pursuant to their respective employment agreements.

The Severance Plan provides that, upon (a) a termination of a Covered Employee’s employment without “cause” (as defined in the Severance Plan) and other than due to death or “disability” (as defined in the Severance Plan) or (b) the Covered Employee’s “resignation for good reason” (as defined in the Severance Plan), in each case outside of the time period beginning with the date on which a “change in control” (as defined in the Severance Plan) occurs and ending 12 months following the change in control, or the “change in control determination period,” the Covered Employee will be entitled to receive: (1) cash severance equal to the product of (x) the sum of (i) the Covered Employee’s annual base salary and (ii) the Covered Employee’s target annual incentive bonus for the year of termination, multiplied by (y) 1 (or 1.5 for Dr. Gano); (2) a cash payment equal to the Covered Employee’s pro rata annual incentive bonus for the year of termination based on actual achievement of the applicable performance goals for such year; (3) payment of premiums for continued coverage under the Company’s group health plans for up to 12 months (or 18 months for Dr. Gano); (4) accelerated vesting of the Covered Employee’s outstanding time-vesting equity awards to the extent such awards were scheduled to vest under their terms based on the Covered Employee’s continued service over the 12-month period (or 15-month period for Dr. Gano) following the date of termination; and (5) vesting of the Covered Employee’s outstanding performance-vesting equity awards to the extent the Compensation Committee determines, in its sole discretion, that the applicable performance goals for such awards have been met as of the date of termination.

In addition, the Severance Plan provides that, upon (a) a termination of a Covered Employee’s employment without “cause” and other than due to death or “disability” or (b) the Covered Employee’s “resignation for good reason, in each case within the change in control determination period, the Covered Employee will be entitled to receive, in lieu of the benefits described above: (1) a cash payment equal to the product of (x) the sum of (i) the Covered Employee’s annual base salary and (ii) the Covered Employee’s target annual incentive bonus for the year of termination, multiplied by (y) 1.5 (or 2 for Dr. Gano); (2) a cash payment equal to the Covered Employee’s pro rata target annual incentive bonus for the year of termination; (3) payment of premiums for continued coverage under the Company’s group health plans for up to 18 months (or 24 months for Dr. Gano); and (4) full vesting acceleration of the Covered Employee’s outstanding equity awards, with performance-vesting equity awards vesting at the greater of (x) the target level of performance or (y) the actual level of performance measured in accordance with the applicable performance goals as of the date of termination, as determined by the Compensation Committee in its sole discretion.

The Severance Plan further provides that, upon the termination of a Covered Employee’s employment due to his or her death or “disability” (as defined in the Severance Plan), the Covered Employee will be entitled to receive full vesting acceleration of the Covered Employee’s outstanding equity awards, with performance-vesting equity awards vesting at the greater of (x) the target level of performance or (y) the actual level of performance measured in accordance with the applicable performance goals as of the date of termination, as determined by the Compensation Committee in its sole discretion.
