Explanation of Responses:
( 1)	The Restricted Stock Units (RSUs), the conversion of which is reported herein, are part of an RSU grant made to the Reporting Person on March 2, 2009 in connection with the Issuer's long-term equity incentive awards for the 2009 fiscal year. The RSUs granted on March 2, 2009 vest in equal installments on April 2, 2010, March 2, 2011, March 2, 2012, and March 2, 2013, and convert into shares of common stock on a one-for-one basis unless the Reporting Person previously selected a longer deferral period. This report reflects the vesting of the first installment of the RSUs and the Reporting Person's acquisition of the underlying shares less a withholding of a sufficient number of shares to pay applicable income taxes. The fair market value of the shares, based on the closing price of the Issuer's stock on April 2, 2010, is $32.07.
