Note 10—Subsequent Events

On April 17, 2017, the Company sold $500,000 of Convertible Notes (the “2017 Notes”) to each of Bay City Capital and the Lender (the “Note Holders”), for a total of $1,000,000 in aggregate principal. The 2017 Notes will convert into common stock if certain conditions are met. In connection with the issuance of the 2017 Notes, the Company also issued warrants to purchase common stock to the Note Holders. See Item 2 “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Recent Developments – Bridge Financing” for more details.

Also on April 17, 2017, the Company entered into a series of agreements, including the Second Amendment of Venture Loan and Security Agreement and a warrant to purchase common stock, to restructure its existing debt under the Loan Agreement with the Lender, which resulted in the deferral of the principal amount due to the Lender on April 1, May 1, and June 1, 2017, and the potential deferral of the principal amount due to the Lender on July 1, August 1 and September 1, 2017, such potential deferral of principal is dependent upon whether, as of June 15, 2017, the Company provides evidence reasonably satisfactory to the Lender that the Company is actively negotiating a clinical services or similar agreement, the terms of which are satisfactory to the Lender, which the Company believes, in good faith, it will enter into no later than September 1, 2017. In exchange for agreeing to defer principal payments, the Lender was granted a warrant to purchase common stock. The number of shares of common stock issuable upon exercise of the warrant is determined by dividing the amount of principal payments deferred by the exercise price of the warrant, which could result in the warrant being exercisable for between approximately 5,519,604 and 11,039,209 shares. The warrant has an exercise price of $0.10438 per share, is exercisable on a net issuance basis and has a 10-year term.
