Explanation of Responses:

( 1 )These securities are restricted stock units ("RSUs"). Each RSU represents a contingent right to receive one share of KnowBe4, Inc.'s (the "Issuer") Class A Common Stock. This amendment corrects the number of RSUs acquired by the Reporting Person on February 22, 2022. ( 2 )This amendment also corrects the number of securities beneficially owned by the Reporting Person on February 22, 2022. The number of securities beneficially owned by the Reporting Person on February 22, 2022 was 233,706. Thus, the securities beneficially owned as reported in Table I, Column 5 of all subsequent Forms 4 for the Reporting Person is similarly understated by 416. As of December 2, 2022, the Reporting Person beneficially owns 211,690 securities.
