Performance Unit Awards.

This pro-rated share of any Performance Unit Award shall be calculated by multiplying: # the Performance Unit Award the Participant would have earned for the full performance period based on the performance of the AEP System Companies as determined at the end of the applicable performance period by # a fraction, the numerator of which is the number of full months of the Participant’s participation from the Grant Date specified in the Performance Unit Award until the Termination Date and the denominator of which is the total number of months in the applicable performance period for the Performance Unit Award.

Each Stock Unit Award shall be credited to the Participant’s Stock Unit Account as of the first day following the end of the calendar quarter for which such Stock Unit Award is granted.

Restricted Stock Unit Awards. Participants shall be considered to have vested in a fractional portion of the Participant’s Restricted Stock Units (and related Dividend Equivalent RSUs) provided that the Participant’s Termination may not otherwise lead to their vesting under the terms of the applicable Restricted Stock Unit Award Agreement issued to the Participant under the LTIP. The portion of Participant’s Granted RSUs (and related Dividend Equivalent RSUs) (as those terms are defined in the applicable Restricted Stock Unit Award Agreement) that vest under this provision is determined as follows:
