Of the $100,000,000 of securities registered on the 2023 S-3, for which the registrant paid a filing fee of $11,020, $91,791,980 of the securities remain unsold, leaving $10,115.48 in previously paid fees available for future offset (calculated at the fee rate in effect on the filing date of the 2023 S-3). In accordance with Rule 457(p) under the Securities Act, the registrant is using $8,700 of the aforementioned unused filing fees previously paid by the registrant in connection with its filing of the 2023 S-3 to offset the remaining filing fee payable in connection with this Registration Statement, and as a result of such offset, the registrant will have $1,415.48 remaining in unused filing fees available to be applied to future filings of the registrant in connection with its filing of the 2023 S-3.</ffd:TermntnCmpltnWdrwl>
