        <footnote id="F1">The original Form 4, filed on March 6, 2018, is being amended by this Form 4 amendment solely to correct an administrative error, which misreported a sale that occurred on December 27, 2017 as a total of 9,200 shares purchased when in fact 0 shares of the Issuer's common shares were purchased. 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 9,200 shares.</footnote>
        <footnote id="F2">Reflects common shares held by the Joseph A. Jolson 1991 Trust, of which Mr. Jolson is a trustee.</footnote>
