In August 2018, the 2017 Plan was amended to extend the post-termination exercise period for vested awards, other than terminations for cause, to up to 10 years. At January 31, 2024 and 2025 , 1,132,959 and 5,795,839 shares, respectively, from the 2017 Plan remained available for future grants.

In accordance with the Plans, the exercise price of an ISO and NSO shall not be less than 100% of the estimated fair value of the shares on the date of grant unless expressly determined in writing by the board of directors or its designated committee, and the exercise price of an ISO granted to a 10% stockholder shall not be less than 110% of the estimated fair value of the shares on the date of grant.
