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.

The restricted stock unit grants vests as follows: 715 shares on 8/1/10, 1,428 shares on 8/1/11 and 2,857 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.
