In connection with the merger transaction between the issuer and Great Plains Energy Incorporated, each share of issuer common stock was converted into the right to receive $1.80 per share plus 0.0856 of a share of Great Plains Energy Incorporated common stock. The Parent Common Stock Value, as defined in the merger agreement dated February 6, 2007, is $25.26 per share. Issuer options converted into options to acquire shares of Great Plains Energy Incorporated common stock upon completion of the merger transaction with Great Plains Energy Incorporated based upon the conversion ratio set forth in the merger agreement. Based on the merger conversion ratio, the exercise price will be computed using a formula that is intended to result in Reporting Person receiving an intrinsic value in the option conversion that will be approximately equal to the intrinsic value of issuer options valued immediately prior to the merger (giving effect to the merger consideration paid by Great Plains Energy Incorporated). The Option Exchange Ratio, as defined in the merger agreement, equals 0.1569. Christopher M. Reitz, Power of Attorney 2008-07-16
