| (2) | On May 10, 2016, the Registrant filed a Registration Statement on Form S-3 (Registration No. 333-211267) (the “2016 Registration Statement”). On November 15, 2018, the Registrant filed a prospectus supplement (the “2018 Prospectus Supplement”) to the 2016 Registration Statement, registered shares of common stock having an aggregate offering price of $150,000,000 and concurrently paid the applicable filing fee of $18,180 (the “Original Filing Fee”). The 2018 Prospectus Supplement related to the Registrant’s offer and sale of shares of the Registrant’s common stock, $0.01 par value per share, from time to time under an at-the-market program (the “Original ATM Program”). On May 9, 2019, the Registrant filed a Registration Statement on Form S-3 (Registration No. 333-231338) (as amended, the “2019 Registration Statement”) and a prospectus supplement (the “2019 Prospectus Supplement”), which superseded the 2016 Registration Statement and 2018 Prospectus Supplement. Pursuant to Rule 415(a)(6) under the Securities Act, securities with an aggregate offering price of $124,372,697 offered by means of the 2019 Prospectus Supplement were unsold securities previously registered on the 2016 Registration Statement, for which a filing fee of $15,074 (as part of the Original Filing Fee) was previously paid by the Registrant. As a result, no additional fee was due in connection with the filing of the 2019 Prospectus Supplement. On March 4, 2020, the Registrant filed a prospectus supplement (the “2020 Prospectus Supplement”) to the 2019 Registration Statement, which superseded the 2019 Prospectus Supplement and registered additional shares of common stock having an aggregate offering price of $25,000,000 for offer and sale under the Original ATM Program. Concurrently with the filing of the 2020 Prospectus Supplement, the Registrant paid a filing fee of $3,245 related to such additional shares. On August 9, 2021, the Registrant filed a prospectus supplement (the “2021 Prospectus Supplement”) to the 2019 Registration Statement, which superseded the 2020 Prospectus Supplement. The 2021 Prospectus Supplement did not register additional securities. As a result, no additional fee was due in connection with the filing of 2021 Prospectus Supplement. On March 4, 2022, the Registrant terminated the Original ATM Program and sales under the 2019 Registration Statement. As of the date of this prospectus supplement, shares of common stock having an aggregate offering price of $22,231,319 remain unsold under the Original ATM Program (the “Unsold Securities”). Pursuant to Rule 457(p) under the Securities Act, a filing fee offset of $2,425, which represents the portion of previously paid filing fees attributable to the Unsold Securities, is available to offset the current filing fee. The Registrant is offsetting the filing fee due under this prospectus supplement by $2,425, with $0.00 remaining to be applied to future filings from this fee offset source. |
