payment date, based on the average of the opening and closing sale price, as
reported in the consolidated transaction reporting system on that date, with
cash dividends that would have been paid on Awards of Stock Units and on
Dividend Equivalents previously credited to such bookkeeping entry account, if
such Stock Units or Dividend Equivalents were Shares. In the case of stock
dividends, the number of Dividend Equivalents credited on each stock dividend
payment date shall be equal to the number of Shares (including fractional
Shares) that would have been issued as a stock dividend in respect of the
Participant's Stock Units and on Dividend Equivalents previously credited to
such bookkeeping entry account, if such Stock Units or Dividend Equivalents were
Shares.

      The Committee may, in its discretion, establish such rules and procedures
governing the crediting of Dividend Equivalents, including timing and payment
contingencies that apply to the Dividend Equivalents, as the Committee deems
necessary or appropriate in order to comply with applicable law.

ARTICLE 13. CHANGE IN CONTROL

      Upon the occurrence of a Change in Control, as defined herein, unless
otherwise specifically prohibited by the terms of Article 17 herein:

      (a) If the Change in Control results solely in a cash payment for the
      outstanding Shares and such Shares cease to be readily tradeable on a
      national securities exchange which is registered under Section 6 of the
      Exchange Act or on NASDAQ, then any and all SARs granted hereunder shall
      be deemed to have been exercised on the date such Change in Control
      occurs;

      (b) If the Change in Control does not result solely in a cash payment for
      the outstanding Shares or such Shares continue to be readily tradeable on
      a national securities exchange which is registered under Section 6 of the
      Exchange Act or on NASDAQ, then any and all SARs granted hereunder shall
      be fully and immediately exercisable and may be exercised at any time in
      full or in part from time to time until the end of the Exercise Period. In
      such event, if the Shares are converted into the common stock, American
      Depositary Share ("ADSs") or American Depositary Receipts ("ADRs") of the
      Person referred to in subsection (1) of Section 2.6, the Surviving
      Corporation or the Parent Corporation, then (i) payments for SARS shall be
      based on the value of the common stock, ADRs or ADSs (as applicable) of
      such Person Surviving Corporation or Parent Corporation and (ii) the Base
      Value and number of SARs shall be appropriately adjusted to reflect the
      per Share consideration received by the holders of the Shares. In the
      event such Change in Control results in payment of a combination of cash
      and other property (including common stock, ADRs or ADSs) for the
      outstanding Shares, the per Share consideration shall be deemed to be the
      change in control price (as such term is defined below).

      (c) Any Vesting Period with respect to Stock Units shall be deemed to have
      expired, and there shall be paid out in cash to Participants within thirty
      (30) days following the effective date of the Change in Control the cash
      payment due with respect to such Stock Units and related Dividend
      Equivalents, with a Valuation Period ending on the effective date of the
      Change in Control. Notwithstanding the foregoing and the provisions of
      Section 7.3, if the Change in Control results in payment of a combination
      of cash and other property for the outstanding Shares, the cash payment
      for each of such Stock Units and related Dividend Equivalents shall be an
      amount equal to the change in control price.

            In addition, if the Change in Control occurs pursuant to the
      transaction described in subsection (3) of Section 2.6, then any
      Participant (i) who had an outstanding Award on the date of the approval
      by the shareholders of the Corporation of such transaction, (ii) whose
      employment is terminated after shareholder approval and prior to the date
      of the occurrence of the Change in Control, by the Company other than for
      cause, by the Participant for good reason (as such terms are defined
      below), or by the acceptance by the participant of a

      position with the acquirer of Niagara Mohawk Power Corporation's nuclear
      facilities, and (iii) who forfeited any Stock Units, Dividend Equivalents
      or SARs as a result of such termination of employment, shall receive a
      cash payment, within thirty (30) days following the date such Change in
      Control occurs, equal to (i) with respect to each forfeited Stock Unit and
      Dividend Equivalent, the change in control price and (ii) with respect to
      each forfeited SAR, the result of multiplying (A) the excess of the change
      in control price over the Base Value of the SAR by (B) the number of
      Shares forfeited under such SAR.

      For purposes of this Article:

      (i) "cause" shall (A) have the meaning ascribed to such term in the
      Participant's employment agreement or change in control severance
      agreement with the Company or a subsidiary, if any, and (B) mean, in the
      absence of an agreement referred to in clause (A), the Participant's
      having (a) materially breached his obligations to the Company or any of
      its subsidiaries, (b) failed in a willful and continued manner to
      substantially perform his duties and responsibilities after a demand for
      substantial performance is delivered to the Participant by a direct
      supervisor or any more senior executive, which specifically identifies the
      manner in which the direct supervisor or executive believes that the
      Participant has not substantially performed his duties, (c) been convicted
      of, or have entered a plea of guilty or nolo contendere to, a felony.

      Market Value of one Share on the date of the Change in Control or (B) the
      cash consideration per Share in such transaction (determined without
      regard to any limits on the number of Shares for which a cash payment will
      be made).

      (iii) "good reason" shall (A) have the meaning ascribed to such term in
      the Participant's employment agreement or change in control severance
      agreement with the Company or a subsidiary, if any, and (B) mean, in the
      absence of an agreement referred to in clause (A), the imposition of a
      requirement that the Participant be based at an office or location other
      than one within a 50-mile radius of the office or a location at which the
      Participant was based immediately prior to approval by the Corporation's
      shareholders of the transaction described in subsection (3) of Section
      2.6, or a reduction in the Participant's base annual salary from the rate
      in effect immediately prior to such shareholder approval.
