*	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 August 1, 2012, the issuer issued 57,000 shares of common stock to the reporting person to settle a grant of performance share awards (the "PSAs") reported in a Form 4 for the reporting person filed on July 24, 2012. The PSAs represented 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 performance criteria, to the extent that the PSAs had vested under separate employment service vesting provisions. The PSAs became fully vested and were settled in accordance with their terms on 08/01/2012.
(2)	Each restricted stock unit represents a contingent right to receive one share of stock. The restricted stock unit grants vested as follows: 1,358 shares on 8/1/10, 2,714 shares on 8/1/11 and 5,428 shares on 8/1/12. The vested shares were issued to the reporting person on the vesting dates, at which time all restrictions on the vested shares lapsed.
