Explanation of Responses:

( 1 )As previously disclosed on the original Form 4, these restricted shares were granted under the 2004 Equity Compensation Plan and were subject to attainment by the Company of a Net Earnings target for fiscal 2009. As the Company did not reach the target, these restricted shares have been cancelled. ( 2 )This amended Form 4 is being filed to report that while these restricted shares, which were awarded under the 2004 Equity Compensation Plan, originally were reported as being subject to attainment by the Company of a Net Earnings target for fiscal 2010, on September 30, 2010, the Compensation Committee of the Board of Directors converted these shares to time-vested shares with four-year cliff vesting. Like the shares noted in Footnote (3), these shares will vest in full (or 100%) on November 12, 2013. ( 3 )As previously disclosed on the original Form 4, these restricted shares are awarded under the 2004 Equity Compensation Plan and vest in full (or 100%) on November 12, 2013. ( 4 )Shares beneficially owned by reporting person in his capacity as a beneficiary of certain irrevocable trusts. The reportingperson disclaims beneficial ownership of these shares except to the extent of his pecuniary interest therein.
