Pursuant to the terms set forth in the Warrants to Purchases Common Stock, issued on January 28, 2020 (the “Warrants”), such Warrants are subject to adjustment in certain circumstances, including in connection with stock splits or if the Company sells common stock at a price lower than the then-exercise price of the Warrants. As a result of a registered direct offering that closed on March 23, 2020 (the “March 2020 Offering”), the exercise price of the Warrants was adjusted to $0.30, the per share price to the public in the March 2020 Offering, upon the closing of the March 2020 Offering on March 23, 2020. As of March 20, 2020, there were 3,755,458 shares of our common stock issuable upon the exercise of outstanding warrants, following such exercise price adjustment.
