Stock Unit Awards. A Participant shall receive a Stock Unit Award for each calendar quarter in respect of his Mandatory Conversion and any Voluntary Conversion applicable to such quarter. Such Stock Unit Award shall equal the number of the Stock Units determined by dividing # the aggregate dollar amount of the Participant’s Director’s Fees that are converted to a Stock Unit Award for the quarter by his Mandatory Conversion and Voluntary Conversion, by # the Fair Market Value of the Common Stock on the last business day of such calendar quarter. 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:

Restricted Stock Unit Awards. Each grant of Restricted Stock Units under the Plan shall be evidenced by an Agreement that # provides for the issuance of Shares to a Participant at such time(s) as the Committee may specify and # contains such other terms and conditions as the Committee may specify, including without limitation, terms that condition the issuance of Restricted Stock Unit Awards upon the achievement of one or more specified Performance Goals.

Grant of Stock Unit Awards. A Stock Unit Award may be granted to any Eligible Employee selected by the Committee. The value of each stock unit under a Stock Unit Award is equal to the Fair Market Value of a Share on the applicable date or time period of determination, as specified by the Committee. A Stock Unit Award shall be subject to such restrictions and conditions as the Committee shall determine. A Stock Unit Award may be granted together with a dividend equivalent right with respect to the Shares subject to the Award, which may be accumulated and may be deemed reinvested in additional stock units, as determined by the Committee in its discretion.

Payment of Stock Unit Awards. A Stock Unit Award shall become payable to a Participant at the time or times determined by the Committee and set forth in the Award Agreement, which shall be made within 60 days following the vesting of the Award. Payment of a Stock Unit Award may be made, at the discretion of the Committee, in cash or in Shares, or in a combination of cash and Shares, subject to applicable tax withholding requirements. Any cash payment of a Stock Unit Award shall be made based upon the Fair Market Value of the Common Stock, determined on such date or over such time period as determined by the Committee.

Performance Unit Awards. A Participant shall be eligible to receive a pro-rated share of any outstanding award of Performance Units granted to a Participant in accordance with the terms of the LTIP (a “Performance Unit Award”), provided that the Participant’s Termination is not due to Termination of Employment Due to the Participant’s Retirement or Triggering Event (as defined in such Performance Unit Award). 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.

Stock Awards. Stock Awards shall have no voting rights. Dividend equivalents declared with respect to a Participant’s Stock Awards in accordance with the underlying program governing the terms of the Stock Award shall be credited to the Participant’s account(s) under the Plan and paid in accordance with the provisions of [Article 7].

Stock Awards. The Committee is authorized to grant a Stock Award under the Plan to any Eligible Person as a bonus, as additional compensation, or in lieu of cash or other compensation the individual is otherwise entitled to receive, in such amounts and subject to such other terms as the Committee in its discretion determines to be appropriate.

“Participant” shall mean an LTIP Participant who has made a Deferral Election to defer the receipt of shares underlying Restricted Stock Unit awards or Performance Stock Unit awards granted under the LTIP.

Stock Unit Award Agreement. Each grant of Stock Units under the Plan shall be evidenced by a Stock Unit Award Agreement between the Participant and the Company. Such Stock Units shall be subject to all applicable terms of the Plan and may be subject to any other terms that are not inconsistent with the Plan. The provisions of the various Stock Unit Award Agreements entered into under the Plan need not be identical.
