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 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 2/27/2006. On that date, the fair market value (FMV) of the issuers stock was $27.81. The RSU vest and are received by the Reporting Person in three equal portions on 3/29/2007, 2/27/2008 and 2/27/2009 unless the Reporting Person has previously elected a longer deferral period. This report reflects the vesting of the 2nd one-third of these RSU, and acquisition of those underlying shares in whole units by the Reporting Person. The FMV of the shares, based on the closing price of the issuers stock on 2/26/2008 (last business day prior to the shares vesting) is $46.91.
(2) The grant of Restricted Stock Units (RSU), reported herein, entitles the Reporting Person to receive shares of the issuer common stock in equal installments of one-third of the original RSU grant on either the later of (i) vesting of the grant or a portion thereof each year which as reported herein is 3/27/09, 2/26/10, and 2/26/11 or (ii) upon the conclusion of such longer deferral period as the Reporting Person may elect in advance. In either occurrence, (i) or (ii), the RSU automatically convert into shares of common stock at no conversion cost to the Reporting Person.
(3) This Restricted Stock Units (RSU) grant is issued pursuant to a provision of the issuer Management Stock Purchase Plan (MSPP) whereby certain directors may make an advance election to receive RSU in lieu of a specified % or dollar amount of that directors annual retainer. RSU are issued in whole units at a 33% discount ($32.60) from fair market value of the issuers common stock on the date the underlying retainer is determined ($48.66) and generally vest 3 years from the date of the award, at which time the RSU convert into shares of common stock on a 1-for-1 basis unless the director previously elected a longer deferral period. The Reporting Person has elected in advance to receive RSU in lieu of his entire annual director retainer fee $36,000 for 2008.
