(1) Pursuant to Instruction 2.A(iii)(b) of Item 16(b) of Form S-3, this information is not required to be included. An indeterminate amount of the securities of each identified class is being registered as may from time to time be offered under this registration statement at indeterminate prices, along with an indeterminate number of securities that may be issued upon exercise, settlement, exchange or conversion of securities offered or sold under this registrations statement, as shall have an aggregate initial offering price up to $150,000,000. Pursuant to Rule 416 under the Securities Act of 1933, as amended, or the Securities Act, this registration statement also covers any additional securities that may be offered or issued in connection with any stock split, stock dividend or pursuant to anti-dilution provisions of any of the securities. Separate consideration may or may not be received for securities that are issuable upon conversion, exercise or exchange of other securities.

(2) Units may be issued under a unit agreement and will represent an interest in one or more securities registered under this registration statement including shares of common stock or preferred stock, debt securities or warrants, in any combination, which may or may not be separable from one another.

(3) Pursuant to Rule 415(a)(6) under the Securities Act, the securities registered pursuant to this registration statement include $93,524,592 of unsold securities (the “Unsold Securities”) previously registered pursuant to the Registration Statement on Form S-3 (File No. 333-226650), which was declared effective on July 15, 2019 (the “Prior Registration Statement”). The Prior Registration Statement registered securities for primary offerings in accordance with Rule 415(a)(1)(x) with a proposed maximum aggregate offering price of $150,000,000. The registrant sold an aggregate of $56,475,408 of such securities under the Prior Registration Statement, leaving the balance of $93,524,592 of Unsold Securities, in respect of which the registrant paid an aggregate registration fee of $11,643 (based on the filing fee rate in effect at the time of the filing of the Prior Registration Statement). Pursuant to Rule 415(a)(6), the filing fee of $11,643 associated with the offering of the Unsold Securities is hereby applied to offset the amount of the filing fee in connection with the $56,475,408 of additional securities registered hereunder. To the extent that, after the filing date hereof and prior to the effectiveness of this registration statement, the registrant sells any Unsold Securities pursuant to the Prior Registration Statement, the registrant will identify in a pre-effective amendment to this registration statement the updated number of Unsold Securities from the Prior Registration Statement to be included in this registration statement pursuant to Rule 415(a)(6) and the updated amount of new securities to be registered on this registration statement. Pursuant to Rule 415(a)(6), the offering of the Unsold Securities under the Prior Registration Statement will be deemed terminated as of the date of effectiveness of this registration statement.
