        <footnote id="F1">The stock options will vest in equal installments on November 29, 2018; November 29, 2019; November 29, 2020; and November 29, 2021.</footnote>
        <footnote id="F2">In a Form 4 filed on December 1, 2017, the reporting person reported that on November 29, 2017 he was granted an employee stock option covering 200,401 shares of common stock and having an exercise price of $12.80 a share (the closing market price of the stock on November 29, 2017). The reporting person and the issuer have agreed to amend the options to provide that the options will have an exercise price of $14.08 a share. The amendment is reported in this Form 4 as a cancellation of the original option and the grant of a replacement option.</footnote>
