Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Each share unit was the economic equivalent of one share of common stock. Upon vesting, the share units were settled (i) 50% in cash based on average of the high and low sale prices of a share of the Company's common stock on the date of settlement (or the average of the high and low sale prices of the common stock on the preceding trading day if the settlement date is not a trading day) and (ii) 50% in shares of the Company's common stock, with any odd or fractional units rounded toward the share units to be settled in cash.
(2) Each share unit represents the economic equivalent of one share of common stock. Upon vesting, the share units are settled (i) 50% in cash based on average of the high and low sale prices of a share of the Company's common stock on the date of settlement (or the average of the high and low sale prices of the common stock on the preceding trading day if the settlement date is not a trading day) and (ii) 50% in shares of the Company's common stock, with any odd or fractional units rounded toward the share units to be settled in cash.
(3) Additional share units accrue when and as dividends are paid on the Company's common stock. The number of share units accrued will be equal to the dollar amount of dividends that would be payable if the share units were actual shares of common stock, divided by the average of the high and low sale prices of a share of the Company's common stock on the date dividends are paid.
(4) Includes 1,052 shares owned jointly with the reporting person's spouse. The number of shares included in Table I, Column 5 as beneficially owned by the reporting person has also been adjusted to remove the duplicative reporting in previous filings of 1,050 shares of common stock jointly owned by the reporting person with her spouse. Those duplicative shares were included in the reporting person's beneficial ownership filings beginning in June 2014.
