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 July 2, 2013, the Compensation Committee of the Board of Directors of the issuer determined that 63,216 shares of the issuer's common stock had been earned by the reporting person under the terms of a grant of performance share awards (the "PSAs"), based on the achievement of specific performance criteria that were not tied solely to the market price of the issuer's common stock. The PSAs were granted to the reporting person on July 1, 2010, and represent the right to receive, upon the settlement of the PSAs, the determined number of earned shares of the issuer's common stock based on the achievement of the performance criteria over a three-year performance period (with the determined number of earned shares being within a range of zero to two times the number of PSAs granted on the award date), to the extent that the PSAs have vested under separate employment service vesting provisions.
(2)	The PSAs vested 1/7th on July 1, 2011, 2/7ths on July 1, 2012, and 4/7ths on July 1, 2013.
