        <footnote id="F1">The SARs became exercisable in 25 percent increments beginning one year from the September 25, 2012 date of grant and on each of the next three grant date anniversaries.  The SARs became fully exercisable on September 25, 2016.</footnote>

    <remarks>On August 28, 2019, the Reporting Person exercised the remaining 18,000 stock-settled stock appreciations rights (SARs) awarded to him effective September 25, 2012. This grant was scheduled to expire on September 25, 2019. Pursuant to the terms of the grant, the exercise of the SARs was settled in shares of the Issuer's Common Stock.  After (1) the deemed disposition of 13,880 shares to the Issuer to account for the award price of the grant and (2) the withholding of 1,282 shares in payment of applicable taxes, the Reporting Person received 2,838 shares of the Issuer's Common Stock, which he continues to hold. This exercise did not involve any open-market sale of the Issuer's Common Stock.</remarks>
