Explanation of Responses:

( 1)

The Restricted Stock Units (RSUs), the conversion of which are reported herein, were issued to the Reporting Person pursuant to issuers Management Stock Purchase Plan (MSPP)on 3/2/09 utilizing a fair market value (FMV) of a share of issuers common stock of $22.23. RSUs are issued in whole units on the basis of a 33% discount from FMV of the issuers common stock on the date the underlying bonus is determined ($14.89 in the 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. The Reporting Person previously elected a deferred distribution. Acquisition price reflects the 33% discount to FMV of issuers stock on grant date. This report reflects the acquisition by the Reporting Person of the common stock underlying the RSUs less shares withheld for application income taxes.
