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 (RSUs), the conversion of which are reported herein, were granted to the reporting person by the issuer as part of the equity incentive grants made by the issuer on February 27, 2006. On that date the fair market value of a share of the issuer's stock was $27.81. The RSUs vest in equal portions over a 3-year period and are received by the reporting person upon vesting unless the reporting person has previously chosen a longer deferral period. This report reflects the vesting of the first one-third of these RSUs, the acquisition by the reporting person of the underlying shares and the withholding by the issuer of sufficient shares to pay income taxes required to be withheld from the reporting person. The fair market value of the shares, based on the closing price of the issuer's stock on March 28, 2007 (last business day before shares vested) is $34.90.

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