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 are reported herein on a one-for-one basis, were granted to the Reporting Person by the issuer as part of equity incentive grants made by the issuer on March 21, 2006. The fair market value (FMV) of the issuers stock on that date was $27.93 per share. The RSU vest in equal portions of one-third of the RSU over a three-year period. This report reflects the vesting of the 2nd one-third of three RSU tranches, the withholding of sufficient shares by the issuer to pay necessary income taxes, and the acquisition by the Reporting Person of the remaining underlying shares at a FMV of $46.05 per share, based on the closing price of the issuers stock on March 20, 2008 (the last business day before the shares vested).
