        <footnote id="F1">The original Form 4, filed on May 27, 2021, is being amended by this Form 4 amendment solely to correct an administrative error that misreported the number of shares acquired by the reporting person under the Company's dividend reinvestment plan as 1,411 shares, when in fact 44 shares were acquired. As a result of this administrative error, the number of shares beneficially owned by the reporting person following the corrected transaction reflects a reduction in the number of shares reported as beneficially owned by the reporting person by 1,367 shares.</footnote>
