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)	Upon vesting of 790 Restricted Stock Units granted to the reporting person on October 5, 2018, the reporting person deferred the receipt of 734 shares of Common Stock and received instead 734 shares of phantom stock pursuant to the Company's 2008 Deferred Compensation Plan. As a result, the reporting person is reporting the disposition of 734 shares of Common Stock in exchange for an equal number of shares of phantom stock.
(2)	Each share of phantom stock represents the right to receive one share of Common Stock.
(3)	As provided in the 2008 Deferred Compensation Plan, the reported phantom stock becomes payable in shares of Common Stock upon termination of the reporting person's service as a director of the Company subject to certain restrictions and limitations.
