Explanation of Responses:

( 1 )This amendment is being filed to correct an administrative error on the original Form 4, where there was a conversion of a derivative security to common stock and the derivative security was reported as acquired rather than disposed of. The footnotes associated with the lines that are being corrected have been renumbered from the numbers used in the original Form 4 in order to consecutively disclose narrative information on this amendment, although the substance of the information remains the same and the appropriate disposition of the derivative security remains the same. ( 2 )Each IRSU was granted under the Company's Management Equity Incentive Plan. Each IRSU represents the right to receive 0.35020 share of common stock of the Company upon satisfaction of the performance goal. The number 59 reported here reflects the result of multiplying the awardee's vested IRSUs by .3502. ( 3 )The underlying RSUs and the IRSUs time vest as to one-twelfth (1/12) of the shares subject thereto on each of the first twelve (12) quarterly anniversaries of October 1, 2010. The performance goal for the IRSUs must have been satisfied by August 31, 2015 or the IRSUs would have automatically forfeited. ( 4 )Each restricted stock unit represents the right to receive one share of common stock of the company. ( 5 )The restricted stock units vest as to one-twelfth (1/12) of the shares subject thereto on each of the first twelve (12) quarterly anniversaries from grant date of October 1, 2010.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
