Common Stock Purchase Agreement

On April 10, 2020, the Company entered into the Common Stock Purchase Agreement with Aspire Capital pursuant to which the Company has the right to sell to Aspire Capital from time to time in its sole discretion up to $20.0 million in shares of the Company’s common stock over the next 30 months, subject to certain limitations and conditions set forth in the Common Stock Purchase Agreement.  The aggregate number of shares that we can sell to Aspire Capital under the Common Stock Purchase Agreement may in no case exceed 1,956,547 shares of the Company’s common stock (which is equal to approximately 19.99% of the common stock outstanding on the date of the Common Stock Purchase Agreement), including the 70,910 commitment shares (the Exchange Cap), unless either (a) shareholder approval is obtained to issue more, in which case the Exchange Cap will not apply, or (b) the average purchase price of all shares sold under the Common Stock Purchase Agreement exceeds $8.461; provided that at no time shall Aspire Capital (together with its affiliates) beneficially own more than 19.99% of the Company’s common stock.  During the three and six months ended June 30, 2021 and 2020, the Company did not sell any shares of its common stock under the Common Stock Purchase Agreement.

Warrants Associated with the March 2018, December 2019, and December 2020 Public Offerings

The outstanding warrants associated with the March 2018, December 2019, and December 2020 public offerings contain a provision where the warrant holder has the option to receive cash, equal to the Black-Scholes fair value of the remaining unexercised portion of the warrant, as cash settlement in the event that there is a fundamental transaction (contractually defined to include various merger, acquisition or stock transfer activities). Due to this provision, ASC 480, Distinguishing Liabilities from Equity, requires that these warrants be classified as liabilities. The fair values of these warrants have been determined using the Black-Scholes valuation model, and the changes in the fair value are recorded in the accompanying unaudited condensed consolidated statements of operations.  During the three and six months ended June 30, 2021, 360,134 and 2,060,000 of the December 2020 public offering warrants and prefunded warrants were exercised for proceeds of $2.6 million and $2,000, respectively.  During the three months ended June 30, 2021 and 2020, the Company recognized gains of $15.3 million and $3.6 million, respectively, in the warrant liabilities fair value adjustment.  During the six months ended June 30, 2021 and 2020, the Company recognized gains of $16.6 million and $8.3 million, respectively, in the warrant liabilities fair

value adjustment.  As of June 30, 2021 and 2020, the fair value of the warrant liabilities was $35.0 million and $51.2 million, respectively.

Warrants Associated with Loan Agreement

In connection with the entry into the Loan Agreement, the Company issued to each of Hercules and SVB a warrant (collectively, the “Warrants”) to purchase shares of the Company’s common stock, par value $0.001 per share (the “Shares”).  The amount of shares that may be purchased for the Warrants, collectively between Hercules and SVB, will not exceed 0.04 multiplied by the aggregate amount of the term loan advances, divided by the exercise price of the Warrants.  At the closing of the Loan Agreement, the Company issued 113,607 warrants to purchase shares of the Company’s common stock and recognized the initial warrants at their relative fair value in shareholder's equity.  In accordance with ASC 815-40, the remaining warrants to purchase shares of the Company’s common stock at closing were recognized at their fair value as warrant liabilities given the variable settlement amount of the warrant shares.  

Warrant Associated with Solar Loan

On the closing date of the Company’s previous loan agreement with Solar, pursuant to the loan agreement the Company issued to Solar the warrant to purchase an aggregate of up to 12,243 shares of the Company’s common stock at an exercise price of $36.754 per share. The warrant will expire five years from the date of the grant. The warrant was classified as equity and recorded at its relative fair value at issuance in the stockholders’ equity section of the balance sheet.
