Explanation of Responses:

1. The Restricted Stock Units (RSUs), the conversion of which is reported herein, were granted to the Reporting Person by the issuer as part of an equity incentive grant made by the issuer on 02/18/05. On that date, the fair market value (FMV) of the issuers stock was $24.90. The Reporting Person previously elected a deferred distribution after the vesting date of 2/18/08. The FMV of the shares, based on the closing price of the issuers stock on 2/17/10 (last day prior to the distribution of the shares), is $31.38.

2. Restricted Stock Units (RSUs), the conversion of which are reported herein, were issued pursuant to the issuer's Management Stock Purchase Plan (MSPP). Under the MSPP, directors may make an advance election to receive RSUs in lieu of a specified percentage or dollar amount of the director's annual retainer. RSUs are issued in whole units only, on the basis of a 33% discount to the fair market value of the issuer's common stock on the date the underlying bonus is determined ($16.61 in this case) or otherwise paid and generally vest three years after the date of the grant, at which time they are converted into shares of the issuer's Common Stock unless the director has previously elected a longer deferral period. This director selected a five-year deferral period. Acquisition price reflects a 33% discount to the fair market value of issuer's stock on grant date. The Reporting Person elected to receive these RSUs in lieu of 100% of his annual director's fee for 2005.
