Explanation of Responses:

1. Ontario Teachers' Pension Plan Board ("OTPP") may, at any time, elect to (a) convert shares of Class B common stock into an equal number of shares of Class A common stock, or (b) convert shares of Class A common stock into an equal number of shares of Class B common stock so long as OTPP holds Class B common stock. The table above does not reflect (i) shares of Class B common stock issuable upon conversion of Class A common stock or (ii) shares of Class A common stock issuable upon conversion of Class B common stock.

2. The reported securities are owned by OTPP. Each of Mr. Blake Sumler, Mr. Ashfaq Qadri, and Mr. Russell Hammond may be deemed to have power to dispose of the shares held by OTPP because of a delegation of authority from the Board of Directors of OTPP, and each expressly disclaims beneficial ownership of such shares.

Remarks:

OTPP has the right to nominate directors for election to the board of directors of the Issuer pursuant to a stockholders agreement, dated June 11, 2020. OTPP has nominated three directors to the Issuer's board of directors. Accordingly, OTPP may be deemed to be a director by deputization.
