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 2/26/2007. On that date, the fair market value (FMV) of the issuers stock was $36.23. The RSU vest and are received by the Reporting Person in six equal portions beginning on 3/28/2008, with each additional portion vesting on the 26th day of February for each subsequent year ending with the last grant on 2/26/2013 unless the Reporting Person has previously elected a longer deferral period. This report reflects the vesting of the first one-sixth of the original RSU award, acquisition of those underlying shares in whole units by the Reporting Person and withholding of sufficient shares to pay applicable income taxes. The FMV of the shares, based on the closing price of the issuers stock on 3/27/2008 (last business day prior to the shares vesting) is $46.70.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
