Effective upon the closing of the Issuers initial public offering (the IPO) which occurred on November 4, 2019 (the IPO Closing), each share of the Issuers Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series C-2 Preferred Stock converted into approximately 0.166 shares of the Issuers Common Stock (on an as-adjusted basis, after giving effect to the 1-for-6 reverse stock split of the Issuers Common Stock effected on July 19, 2019). Unless otherwise noted herein, all shares of Common Stock and per share amounts have been adjusted to reflect the reverse stock split.

In July 2014, TCG II LP purchased certain preferred shares of Flexus Biosciences, Inc. (Flexus). In April 2015, Flexus contributed and assigned to the Issuer certain of its assets and rights in exchange for Series A Preferred Stock of the Issuer (the Series A Shares). Flexus immediately distributed the Series A Shares to its preferred stockholders, including 2,681,963 Series A Shares distributed to TCG II LP, and was subsequently acquired by a third party. The fair market value of the Series A Shares distributed to TCG II LP at the time of distribution was approximately $2,681,963. In April 2015, TCG II LP purchased an aggregate of 12,100,000 shares of Series A Preferred Stock (the Series A Shares) for an aggregate purchase price of $12,100,000.

In December 2018, Ponoi LP purchased an aggregate of 872,410 shares of Series C-2 Preferred Stock (the Series C-2 Shares and, together with the Series A Shares, the Series B Shares and the Series C Shares, the Preferred Stock) for an aggregate purchase price of $2,000,000 and Ponoi II LP purchased an aggregate of 872,410 Series C-2 Shares for an aggregate purchase price of $2,000,000.

Additionally, TCG II LP purchased 625,000 shares of Common Stock as part of the Issuers IPO for an aggregate purchase price of $7,500,000. Upon the IPO Closing, each share of Preferred Stock automatically converted into approximately 0.166 shares of Common Stock.

The Reporting Persons also retain the right to change their investment intent at any time, to acquire additional shares of Common Stock or other securities of the Issuer from time to time, or to sell or otherwise dispose of all or part of the Common Stock beneficially owned by them (or any shares of Common Stock into which such securities are converted) in any manner permitted by law.
