______________

*At December 31, 2018, the conversion of the convertible notes into convertible preferred stock was dependent on the outstanding loan balance including accrued interest and the conversion stock per share price at the date of Qualified Equity Financing, Change of Control, Liquidation, or Prepayment Conversion (see Note 6). These factors were not estimable and the number of convertible preferred stock was not determinable. These convertible notes converted to Series G-1 convertible preferred in April 2019 (Note 10)
