(1) The proposed maximum aggregate offering price is being used to calculate the registration fee pursuant to Rule 457(o) under the Securities Act of 1933, as amended.

(2) The registrant previously paid a registration fee of $7,496 in connection with the offering of shares of our common stock having an aggregate offering price of up to $75,000,000 pursuant to a sales agreement prospectus under an automatic shelf registration statement on Form S-3ASR (File No. 333-254661), originally filed with the Securities and Exchange Commission on March 24, 2021. As of the date hereof, shares of common stock having a maximum aggregate offering price of $49,710,253.37 remain unsold under the sales agreement prospectus (the offering of which unsold securities has been terminated). Pursuant to Rule 457(p) under the Securities Act, we are partially offsetting the registration fee of $22,040 due in connection with the sales agreement prospectus by the amount that was previously paid. Accordingly, the registrant is paying the registration fee due of $22,040, less the $5,423.39 that was previously paid, or $16,616.61.
