        <footnote id="F1">Upon the vesting of restricted stock granted to the reporting person on January 4, 2016, the reporting person deferred receipt of 2,713.2234 shares of common stock and instead received 2,713.2234 phantom stock units pursuant to the Directors Deferred Compensation Plan (DDCP).  As a result, the reporting person is reporting the disposition of 2,713.2234 shares of common stock in exchange for an equal number of phantom stock units.</footnote>
        <footnote id="F2">One-for-one.</footnote>
        <footnote id="F3">These phantom stock units were accrued under the DDCP and are to be settled in accordance with the terms of the plan.</footnote>
        <footnote id="F4">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>
