This sale reported on this Form 4 was effected pursuant to the Issuer's policy requiring sell-to-cover to satisfy certain tax obligations of the Reporting Person incurred with the vesting and settlement of certain Restricted Stock Units (RSUs). | Each RSU represents a contingent right to receive one share of Class B Common Stock. | The shares of Class B Common Stock are to be acquired upon the vesting of an RSU award previously granted to the Reporting Person. The RSUs shall vest as follows: 1/16 of the shares subject to the RSU vest in sixteen equal quarterly installments measured from January 27, 2022 and the Issuer's achievement of a specified average price per share prior to the earlier of (i) the five year anniversary of the effectiveness of the registration statement on Form S-1 filed by the Issuer in connection with the Issuer's initial public offering and (ii) the expiration of the RSU award, subject to the Reporting Person continuing to have a Service Relationship (as defined in the Issuer's Amended and Restated 2014 Stock Option and Grant Plan) as a full time employee of the Issuer on each such date. | Each share of Class B Common Stock held by the Reporting Person will automatically convert into one share of Class A Common Stock upon the sale or transfer of such share of Class B Common Stock, subject to certain exceptions, and in certain other circumstances described in the Issuer's amended and restated certificate of incorporation. Each share of Class B Common Stock is also convertible at any time at the option of the Reporting Person into one share of Class A Common Stock. | The shares are held of record by Arvind Nithrakashyap, as Trustee of the Nithrakashyap/Chatterjee Revocable Trust, for which the Reporting Person serves as trustee and shares voting and dispositive power with his spouse.
