**Performance Shares will be earned based on TSR of Evergy, Inc. between June 5,
2018, and December 31, 2019 (the “Evergy Measurement Period”). The Grantee must
remain employed by the Company through the date the Performance Shares are paid
in order to receive any Performance Shares earned based on the TSR percentile
rank achieved during the Evergy Measurement Period.

1 TSR is compared to an industry peer group of the Edison Electric Institute
(EEI) index of electric companies during the applicable measurement period
(i.e., the Great Plains Energy Measurement Period or the Evergy Measurement
Period). At the end of and with respect to each measurement period, the
Committee will assess total shareholder return compared to the EEI index for the
applicable measurement period. Depending on Great Plains Energy’s or Evergy’s
percentile rank, as applicable, the Grantee will receive a percentage of the
Performance Share Award. Interpolation will be used to determine payouts if
percentile rank of relative total shareholder return falls between the
percentile ranks shown.
