Any securities registered under this registration statement may be sold separately or as units with other securities registered under this registration statement. Pursuant to Rule 416 under the Securities Act of 1933, as amended (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. (1b) The proposed maximum offering price per security and proposed maximum aggregate offering price per class of security will be determined from time to time by the registrant in connection with the issuance by the registrant of the securities registered hereunder and is not specified as to each class of security pursuant to the Instructions to the Calculation of Filing Fee Tables and Related Disclosure of Form S-3 under the Securities Act. (1c) The proposed maximum aggregate offering price is estimated solely for the purpose of calculating the registration fee pursuant to Rule 457(o) under the Securities Act. Subject to Rule 462(b) under the Securities Act, the aggregate maximum offering price of all securities issued by the registrant pursuant to this registration statement will not exceed $150,000,000.00.</ffd:OfferingNote>

    <ffd:OffsetNote contextRef="ofst_2" id="ixv-625">On December 9, 2022, the registrant filed a registration statement on Form S-3 (File No. 333-268733), registering the issuance of $100,000,000.00 of securities of the registrant (the "Prior Registration Statement"). In connection with the filing of the Prior Registration Statement a fee of $11,020.00 was due, which the registrant satisfied through (i) claiming a fee offset of $7,185.00 pursuant to Rule 457(p), and (ii) a contemporaneous fee payment in the amount of $3,835.00. Pursuant to Rule 457(p) under the Securities Act, the registration fee applicable to the securities registered hereby in the amount of $20,715.00 is offset by $3,835.00 in registration fees previously paid by the registrant with respect to the registrant's securities that were registered but not issued pursuant to the Prior Registration Statement. Accordingly, a registration fee of $16,880.00 is being paid at this time. The Prior Registration Statement is hereby withdrawn and any offering of the unsold securities thereunder has been terminated.</ffd:OffsetNote>
