 WHEREAS,
Section 4.3(b)(ii) of the Amended and Restated Certificate and the Prospectus provide that the Initial Conversion Ratio shall be adjusted (the “Adjustment”) in the event that additional shares of Class A Common

equity-linked securities issued or deemed issued in connection with the Transaction, excluding any shares or equity-linked securities issued, or to be issued, to Tema or its designees in connection with the Transaction or pursuant to Warrants issued

private placement (the “New Issuance”);

Certificate, and the New Issuance would result in an Adjustment to the Initial Conversation Ratio pursuant to the Adjustment Provision;

WHEREAS, in connection with the Transaction, KLR Sponsor desires to (i) waive its right to receive certain additional shares of
Class A Common Stock upon conversion of its shares of Class F Common Stock in connection with the Transaction as a result of the Adjustment to the Initial Conversion Ratio pursuant to the Adjustment Provision caused by the New Issuance and
(ii) cap the number of Warrants held by KLR Sponsor as of immediately prior to the consummation of the Transaction.
