Notes Payable to Investors

4. Notes Payable to Investors

In 2016, Aerpio entered into a senior secured convertible note financing (the “Convertible Notes” or the “Convertible Note Financing”) totaling approximately $9,000,000.  The Convertible Notes accrued interest at 8% per annum, compounded annually. The Convertible Notes were subject to mandatory prepayment upon the occurrence of certain events, such as a liquidation, dissolution or sale of Aerpio. In addition, and prior to maturity, the Convertible Notes were automatically convertible into shares of Aerpio capital stock upon the occurrence of a sale of Aerpio’s capital stock in a single transaction resulting in gross proceeds to Aerpio of $30,000,000 (hereinafter referred to as an “Investor Sale”). The type and class of Aerpio capital stock issued to the holder of each Convertible Note upon conversion would have been identical to the type and class of Aerpio capital stock issued in the Investor Sale. The holder of each Convertible Note was entitled to a number of shares of Aerpio capital determined by dividing (i) the outstanding principal amount of the Convertible Note plus any unpaid accrued interest by (ii) an amount equal to the price per share of Aerpio capital stock paid by the purchasers of such shares in connection with the Investor Sale. The Convertible Notes were secured by a first priority perfected security interest in all of the Aerpio’s assets.

In October 2016 and February 2017, Aerpio executed additional senior secured Convertible Note financings (the “Additional Convertible Notes” or the “Additional Convertible Note Financings”) totaling approximately $3,500,000 and $300,000, respectively, with certain investors of Aerpio. The terms of the Additional Convertible Notes were identical to the Convertible Notes and were treated as extensions of the original Convertible Note Financing. The Company incurred $125,935 of costs associated with these transactions, which were amortized to the maturity date of March 31, 2017.  In connection with the Additional Convertible Note Financings, the Convertible Notes were amended and their respective maturity dates were extended from October 31, 2016 to March 31, 2017. The amendments were accounted for as a modification for accounting purposes.

In connection with the Merger (Note 1) the Convertible Notes, Additional Convertible Notes and accrued interest were converted into the Company’s common stock.
