(1) On August 1, 2011, the issuer issued 4,369 shares of common stock to the reporting person in a settlement conversion of a performance share award (the "PSA") reported in a Form 4 for the reporting person filed on July 29, 2011. The PSA represented the right to receive, upon the settlement of the PSA, the determined number of earned shares of the issuer's common stock based on the achievement of performance criteria, to the extent that the PSA had vested under separate employment service vesting provisions. The PSA became fully vested and was settled in accordance with its terms on 08/01/2011.
(2) Each restricted stock unit represents a contingent right to receive one share of stock. The restricted stock unit grants vests as follows: 679 shares on 8/1/10, 1,357 shares on 8/1/11 and 2,714 shares on 8/1/12. The vested shares will be issued to the reporting person on the vesting dates, at which time all restrictions on the vested shares will lapse.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
