Explanation of Responses:
1. Includes 2,665 restricted stock units ("RSUs"), each of which represents a contingent right to receive one share of Common Stock of the Issuer. The RSUs fully vest on the one-year anniversary of the grant date, subject to the Reporting Person's continuous service to the Issuer.
2. Each share of the Issuer's convertible Preferred Stock will automatically convert into one share of Common Stock upon the closing of the Issuer's initial public offering ("IPO").
3. On May 7, 2020, the Issuer issued to the Reporting Person's trust, Bao Trust Dated Mar-10 2020, a convertible note with a principal amount of approximately $270,628 (the "2020 Note"). The 2020 Note accrues non-compounding interest at a rate of 4.0% per annum and matures seven years following the date of issuance, unless earlier converted pursuant to its terms. At the execution of the underwriting agreement in connection with the IPO, the outstanding principal balance of the 2020 Note plus any accrued and unpaid interest will automatically convert into shares of Common Stock at a ratio based on a conversion price equal to $340.0 million plus any consideration paid by the noteholder for the 2020 Note divided by the Issuer's fully-diluted capitalization on August 5, 2020.
