Explanation of Responses:
( 1)	The Restricted Stock Units (RSUs), the conversion of which are reported herein, were issued to the Reporting Person pursuant to issuer's Management Stock Purchase Plan (MSPP) on 3/02/09 utilizing a fair market value (FMV) of a share of issuer's common stock of $22.23. RSUs 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 ($14.89 in this case) and generally vest 3 years from date of grant, at which time they convert into shares of common stock unless the executive has previously selected a longer deferral period. Acquisition price reflects the 33% discount to FMV of issuer's stock on grant date. This report reflects the acquisition by the Reporting Person of the common stock underlying the RSUs minus sufficient shares withheld by the issuer at the request of the Reporting Person as necessary to pay applicable income taxes.
( 2)	The Restricted Stock Units (RSUs), 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 3/02/09 utilizing a fair market value (FMV) of a share of the issuer's stock of $22.23. The RSU grant vests in equal portions over a four year period, and are received by the Reporting Person upon vesting, on a one-for-one basis unless the Reporting Person has previously chosen a longer deferral period. This report reflects the vesting of a one-fourth portion of the original RSU grant and the acquisition by the Reporting Person of the common stock underlying the RSU minus sufficient shares withheld by the issuer at the request of the Reporting Person as necessary to pay applicable income taxes.
