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, were granted to the Reporting Person by the issuer as part of equity incentive grants made by the issuer on February 18, 2005. On that date the fair market value (FMV) of a share of the issuer's stock was $24.90. The RSU grant vests in equal portions over a three (3) year period from the date of the award 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 all of the RSU from the original grant and the acquisition by the Reporting Person of the underlying shares. The FMV of the shares, based on the closing price of the issuer's stock on February 15, 2008 (last business day before shares vest) is $43.11.
(2)	The Restricted Stock Units (RSU), the conversion of which is reported herein, were issued to the Reporting person pursuant to issuer's Management Stock Purchase Plan (MSPP) on 2/18/05. On that date the fair market value (FMV) of a share of issuer's common stock was $24.90. Under MSPP, directors may make an advance election to receive RSU in lieu of a specified % or dollar amount of director's annual retainer. RSU are issued in whole units on the basis of a 33% discount from FMV of the issuer's common stock on the date the underlying bonus is determined ($16.68 in this case) and generally vest 3 years from date of grant, at which time they convert into shares of common stock unless the director has previously selected a longer deferral period. Acquisition price reflects the 33% discount to FMV of issuer's stock on grant date. The Reporting Person elected to receive these RSU in lieu of the entire annual director retainer fee of $27,500 for 2005.
