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) On March 16, 2016, the Issuer declared a quarterly dividend of $15.625 per share on its 6.25% Series B Mandatory Convertible Preferred Stock, payable on April 15, 2016, to holders of record on April 1, 2016. The dividend was paid in shares of common stock based on the Volume Weighted Average Price per share over the five consecutive trading day period ending on the second trading day immediately preceding the applicable dividend payment day, multiplied by 97%.
(2) On June 14, 2016, the Issuer declared a quarterly dividend of $15.625 per share on its 6.25% Series B Mandatory Convertible Preferred Stock, payable on July 15, 2016, to holders of record on July 1, 2016. The dividend was paid in shares of common stock based on the Volume Weighted Average Price per share over the five consecutive trading day period ending on the second trading day immediately preceding the applicable dividend payment day, multiplied by 97%.
(3) On September 21, 2016, the Issuer declared a quarterly dividend of $15.625 per share on its 6.25% Series B Mandatory Convertible Preferred Stock, payable on October 17, 2016, to holders of record on October 1, 2016. The dividend was paid in shares of common stock based on the Volume Weighted Average Price per share over the five consecutive trading day period ending on the second trading day immediately preceding the applicable dividend payment day, multiplied by 97%.
(4) Each Depositary Share represents a 1/20th interest in a share of the Issuer's 6.25% Series B Mandatory Convertible Preferred Stock, $0.01 par value per share (the "Series B Preferred Stock"). At any time prior to January 15, 2018, a holder of 20 Depositary Shares may cause the conversion of one share of the Series B Preferred Stock into a number of shares of the Issuer's Common Stock equal to the minimum conversion rate of 37.0028, subject to adjustments for certain fundamental changes (as defined). Thus, each Depositary Share will convert into 1.85014 shares of Common Stock, subject to adjustment. On approximately January 15, 2018, the Depositary Shares mandatorily convert to Common Stock at a conversion rate ranging from 1.85014 to 2.1739 shares of Common Stock per Depositary Share (or a Series B Preferred Stock to Common Stock conversion rate ranging from 37.0028 to 43.4782 shares), subject to adjustment.
(5) Nonqualified stock options become exercisable in three equal installments beginning on the first anniversary of the grant date specified in Column 3 or immediately upon death, disability, retirement at age 65 with required years of service, or a change in control.
