December 2020 Purchase Agreement with Lincoln Park Capital Fund, LLC

On December 4, 2020, the Company entered into the 2020 Lincoln Park PA Purchase Agreement with Lincoln Park to place up to $100.0 million in the aggregate of the Company's common stock on an ongoing basis over a term of 36 months. The Company controls the timing and amount of any sales to Lincoln Park, and Lincoln Park is obligated to make purchases in accordance with the December 2020 PA. Any common stock that is sold to Lincoln Park will occur at a purchase price that is based on an agreed upon fixed discount to the Company's prevailing market prices at the time of each sale and with no upper limits to the price Lincoln Park may pay to purchase common stock. The agreement may be terminated by the Company at any time, in its sole discretion, without any additional cost or penalty.

The December 2020 PA specifically provides that the Company may not issue or sell any shares of its common stock under the agreement if such issuance or sale would breach any applicable rules of the NYSE American Stock Exchange (“NYSE American”). In particular, NYSE American General Rule 713(a) provides that the Company may not issue or sell more than 19.99% of the number of shares of the Company’s common stock that were outstanding immediately prior to the execution of the December 2020 PA unless (i) shareholder approval is obtained or (ii) the average price of all applicable sales of common stock to Lincoln Park under the December 2020 PA, equals or exceeds $6.15. The Company held its 2021 Annual Shareholders Meeting on May 21, 2021 and obtained shareholder approval for the issuance of more than 19.99% of the shares of the Company’s common stock outstanding under the December 2020 PA.

Lincoln Park has no right to require the Company to sell any shares of common stock to Lincoln Park, but Lincoln Park is obligated to make purchases as the Company directs, subject to certain conditions. In all instances, the Company may not sell shares of its common stock to Lincoln Park under the 2020 Lincoln Park PA if it would result in Lincoln Park beneficially owning more than 9.99% of its common stock at any one point in time.

During the three months ended March 31, 2022, the Company did not sell any shares of common stock pursuant to the 2020 Lincoln Park PA compared to 3.8 million shares for net proceeds of $24.9 million for the three months ended March 31, 2021.

On April 14, 2017, the Company entered into the ATM Offering Agreement with Cantor acting as the sales agent. Under the ATM Offering Agreement, the Company may from time to time sell shares of its common stock in “at-the-market” offerings. The Company pays Cantor a commission of up to 2.5% of the gross proceeds from the sale of any shares pursuant to the ATM Offering Agreement.

During the three months ended March 31, 2022, the Company sold 7.4 million shares of common stock for net proceeds of $15.6 million pursuant to the ATM Offering Agreement. The Company sold 9.3 million shares of common stock for net proceeds of $47.3 million pursuant to the ATM Offering Agreement for the three months ended March 31, 2021.
