Explanation of Responses:

1. The number of shares of common stock reflects a 1-for-6 reverse stock split, which became effective July 19, 2019.

2. The shares are held directly by The Wong Family Trust Dated February 4, 2008 for which the Reporting Person is a trustee.

3. Each share of Series B Preferred Stock is convertible into approximately 0.166 shares of the Issuer's common stock upon the closing of the Issuer's initial public offering (on an adjusted basis, after giving effect to the 1-for-6 reverse stock split of the common stock effected by the Issuer on July 19, 2019). Shares of Series B Preferred Stock have no expiration date and will automatically convert into shares of the Issuer's common stock upon the closing of the Issuer's initial public offering of common stock, for no additional consideration.

4. Twenty-five percent of the shares subject to the option vests on the first anniversary of the vesting commencement date, and the remainder vests in 36 equal monthly installments thereafter for the following three years.
