        <footnote id="F1">Includes shares acquired pursuant to dividend reinvestment in transactions exempt from Section 16 pursuant to Rule 16a-11.</footnote>
        <footnote id="F2">Upon the vesting of restricted stock granted to the reporting person on January 2, 2018, the reporting person deferred receipt of 2,114.9256 shares of common stock and instead received 2,114.9256 phantom stock units pursuant to the Directors Deferred Compensation Plan (DDCP).  As a result, the reporting person is reporting the disposition of 2,114.9256 shares of common stock in exchange for an equal number of phantom stock units.</footnote>
        <footnote id="F3">One-for-one.</footnote>
        <footnote id="F4">These phantom stock units were accrued under the DDCP. Prior Forms 4 stated that phantom stock units accrued under the DDCP were to be settled following the reporting person's termination of service as a director. However, the DDCP also allows for in-service distributions prior to termination of service.</footnote>
        <footnote id="F5">Includes phantom stock units accrued pursuant to a dividend reinvestment feature of the DDCP in transactions exempt from Section 16 pursuant to Rule 16a-11.</footnote>
