        <footnote id="F1">The initial Form 3 filed by the reporting person reported direct ownership of 1,399 shares of common stock, which inadvertently included 600 restricted stock units that should have been reported in Table II. The number of shares of common stock reported in Table I should have been 799.  On November 3, 2017, the reporting person filed an amendment to the Form 3 to correct this error; however, the filing software used to make the filing added the corrected number of shares of common stock (that is, 799) to the original 1,399 shares reported, which resulted in the amendment showing 2,198 shares directly owned.  This amendment is being filed to restated the number of shares of common stock owned to 799 shares.</footnote>
