The Shares are to be issued and sold by the Company pursuant to an Amended and Restated Capital on Demand™ Sales Agreement, dated July 29, 2019 (the “Original Sales Agreement”), as amended by Amendment No. 1 to Amended and Restated Capital on Demand™ Sales Agreement, dated July 27, 2021 (the “Amendment”), by and among the Company and JonesTrading Institutional Services LLC and B. Riley Securities, Inc. (f/k/a B. Riley FBR, Inc.) (the Original Sales Agreement, as amended by the Amendment, the “Sales Agreement”). The Original Sales Agreement was filed with the Commission as Exhibit 1.1 to the Company’s Current Report on Form 8-K, filed on July 30, 2019. The Amendment is being filed with the Commission as Exhibit 10.2 to the Company’s Quarterly Report on Form 10-Q, filed on the date hereof. We are acting as counsel for the Company in connection with the issue and sale by the Company of the Shares.
