Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	The transaction reported herein reflects the gift by the reporting person of shares to a charitable trust.
(2)	The Restricted Stock Units (RSU), the conversion of which is reported herein, were granted to the Reporting Person by the issuer as part of equity incentive grants made by the issuer on 2/26/2007. On that date, the fair market value (FMV) of the issuers stock was $25.39. The RSU originally were to vest in four equal portions on 3/27/2008, 2/26/2009, 2/26/2010 and 2/26/2011. This report reflects the accelerated vesting of the remaining unvested RSU, acquisition of those underlying shares in whole units by the Reporting Person and withholding of sufficient shares to pay applicable income taxes in accordance with the provisions of the Amended and Restated Retirement Agreement between the Reporting Person and the company. The FMV of the shares, based on the closing price of the issuers stock on 3/14/2008 (last business day prior to the shares vesting) is $45.55.
(3)	The Restricted Stock Units (RSU), the conversion of which is reported herein, were granted to the Reporting Person by the issuer as part of equity incentive grants made by the issuer on 2/27/06. On that date, the fair market value (FMV) of the issuers stock was $27.81. The RSU originally were to vest in four equal portions on 3/27/2007, 2/27/2008, 2/27/09 and 2/27/2010. This report reflects the accelerated vesting of the remaining unvested RSU, acquisition of those underlying shares in whole units by the Reporting Person and withholding of sufficient shares to pay applicable income taxes in accordance with the provisions of the Amended and Restated Retirement Agreement between the Reporting Person and the company. The FMV of the shares, based on the closing price of the issuers stock on 3/14/2008 (last business day prior to the shares vesting) is $45.55.
