&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Each share of Class B Common Stock is convertible into one share of Class A Common Stock at any time and will convert automatically upon certain transfers and upon the earlier of (i) the
 date specified by a vote of the holders of 66 2/3% of the then outstanding shares of Class B Common Stock, (ii) seven years from the effective date of the IPO (as defined in the Schedule 13D), (iii) the first date following the IPO on
 which the number of shares of outstanding Class B Common Stock (including shares of Class B Common Stock subject to outstanding stock options) held by Tomer Weingarten, including certain entities that Mr. Weingarten controls, is less
 than 25% of the number of shares of Class B Common Stock (including shares of Class B Common Stock subject to outstanding stock options) that Mr. Weingarten originally held as of the date of the IPO, (iv) the date fixed by the Issuer's
 board of directors (the "Board"), following the first date following the completion of the IPO when Mr. Weingarten is no longer providing services to the Issuer as an officer, employee, consultant or member of the Board, (v) the date
 fixed by the Board following the date, if applicable, on which Mr. Weingarten is terminated for cause, as defined in the Issuer's restated certificate of incorporation, and (vi) the date that is 12 months after the death or disability,
 as defined in the Issuer's restated certificate of incorporation, of Mr. Weingarten.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Based on the quotient obtained by dividing (a) the aggregate number of shares of Class A Common Stock and Class B Common Stock beneficially owned by the Reporting Person, by (b) the sum
 of (i) 235,013,639 shares of Class A Common Stock outstanding as of March 24, 2023, as reported in the 10-K, and (ii) the number of shares of Class B Common Stock beneficially owned by the Reporting Persons. The number of shares of
 Class B Common Stock beneficially owned by the Reporting Person(s) are treated as converted into Class A Common Stock only for the purpose of computing the percentage ownership of the Reporting Person for the purpose hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) The Class B Common Stock has 20 votes per share, and the Class A Common Stock has one vote per share. The percentage ownership of the Reporting Person reported herein does not give
 effect to the 20 votes per share of Class B Common Stock because the shares of Class B Common Stock are treated as converted into Class A Common Stock for the purpose hereof.

------

On the date hereof, the Reporting Persons beneficially own an aggregate of 3,646,919 shares of Class A Common Stock and 30,999,311 shares of Class B Common Stock, which represent approximately 13.0% of the Class A Common Stock outstanding (calculated in accordance with footnote (2) above). If all outstanding shares of Class B Common Stock (as reported in the 10-K) were deemed converted into Class A Common Stock, the Reporting Persons would be deemed to beneficially own approximately 12.0% of the shares of Class A Common Stock deemed outstanding.

Each of the Reporting Persons shares voting and dispositive power over the shares of Class A Common Stock and Class B Common Stock held directly by the IVP X Funds, IP XI Funds and IP X FOF Funds.

Each of Holdings, IVA X Ltd, IA XI Ltd, IA X FOF Ltd, IVA X, IA XI, IA EU XI and IA X FOF expressly declares that nothing herein shall be construed as an admission that it is, for the purposes of sections 13(d) or 13(g) of the Act or for any other purpose, the beneficial owner of any securities covered hereby.

To the Reporting Persons' knowledge, no shares of Class A Common Stock or Class B Common Stock are beneficially owned by any Scheduled Person (as defined in the Schedule 13D).

**Item 7. Material to Be Filed as Exhibits.**

Exhibit 7.1 Joint Filing Agreement, dated July 12, 2021, by and among the Reporting Persons (incorporated by reference to Exhibit 7.1 to the Schedule 13D filed on behalf of the Reporting Persons with the SEC on July 12, 2021).
