"Individual Performance Payout Percentage" shall mean (i) in the case of an Employee who is rated as performing in the "A" category, 120%, (ii) in the case of an Employee who is rated as having performed in the "B" category," 100%, and (iii) in the case of an Employee who is rated as performing in the "C" category, 0%. The Total Award Amount as so determined for an Employee shall be subject to adjustment as provided in Sections 4, 5, and 6 (as so adjusted, the "Adjusted Total Award Amount"). (b) Subject to Section 8, the Adjusted Total Award Amount for an Employee shall be paid (i) in the case of a Rated Employee, after the application of Section 10.2, 100% in cash, and (ii) in the case of all other Employees, 25% in shares of Common Stock (the amount payable in shares of Common Stock being referred to herein as the "Stock Payment Amount"), and after application of Section 10.2, the remainder in cash. 4. Reduction of Total Award Amount in Certain Instances. 4.1 Partial Year of Employment. In the event that: (a) an Employee (i) is first placed on the management or executive payroll after January 1, 1998 and prior to December 1, 1998, (ii) is on a voluntary leave of absence or long-term disability during 1998, (iii) retires under the pension plan of any of the Employers during 1998, or (iv) dies during 1998, or (b) an Employee's employment with the Employers is terminated during 1998 as a result of (i) the sale, permanent closure or other disposition of any generation facility, (ii) the sale or other disposition of any business unit or functional group (or portion thereof) that includes such Employee, or (iii) the Employer's decision to have a third party provide the services provided by the functional group that includes such Employee, then the Total Award Amount with respect to such Employee will be prorated by multiplying it by a fraction, the numerator of which is the number of days the Page 3 of 6 Employee worked for an Employer (or Employers) during 1998 and the denominator of which is 365. 4.2 Other Incentive Plans. In the event that during 1998, an Employee participates in or is or becomes eligible to participate in, any sales or group incentive plan that precludes receipt of an Award hereunder (such incentive plans collectively referred to herein as "Other Incentive Plans"), then the Total Award Amount with respect to such Employee will be prorated (after any adjustment required by Section 4.1) by multiplying it by a fraction, the numerator of which is the total number of days during 1998 that the Employee worked for an Employer (or Employers) and was not a participant in, or eligible to participate in, the Other Incentive Plans, and the denominator of which is the total number of days the Employee worked for an Employer (or Employers) during 1998. For purposes of this Section 4, the number of days an Employee worked for an Employer (or Employers) during 1998 shall include, solely in the case of an Employee who retires under the pension plan of any Employer or who dies, the total number of days in the calendar month in which such Employee retires or dies. 5. Part-Time Employees. For an Employee who is a part-time Employee (as determined in accordance with his or her Employer's personnel practices), the Total Award Amount will be prorated by multiplying it by a fraction, the numerator of which is the number of hours the Employee was scheduled to work for an Employer (or Employers) during 1998 and the denominator of which is 2080. This Section 5 shall be applied prior to the application of Section 4.1 for any Employee who is described therein. 6. Transfer of Employee from One Business Unit or Production Facility to Another Business Unit or Production Facility. In the event that an Employee is transferred from one business unit to another business unit or production facility during 1998, the Total Award Amount for such Employee will equal the sum of the amounts determined on a prorated basis from each business unit. 7. Settlement of Awards. Payment of the Adjusted Total Award Amount, if any, will be made to an Employee as soon as practicable after the Company's audited financial results are available for calendar year 1998. The number of shares of Common Stock payable as part of any Stock Payment Amount to an Employee shall be computed by dividing the Stock Payment Amount by the value of one share of Common Stock; provided, however, that shares that may Page 4 of 6 become payable to an Employee hereunder shall not be issued if the aggregate number of shares payable to such Employee does not exceed 25 (and, in such case, cash shall be paid in an amount equal to the value of the shares that would have been issued but for this proviso). Fractional shares of Common Stock that may become payable to an Employee hereunder shall be awarded if the shares awarded to such Employee exceed 25 and are held in non-certificated, book-entry or electronic form; otherwise, any such fractional shares shall be paid in cash. For purposes of this Section, the value of a share of Common Stock shall be the average of the closing prices of a share of Common Stock as reported in The Wall Street Journal as New York Stock Exchange Composite Transactions during the last calendar quarter of 1998 (appropriately adjusted for any stock-split, stock dividend or other similar event). 8. Termination of Employment. An Employee whose employment with all Employers terminates on or prior to December 31, 1998 for any reason other than those described in Section 4.1 shall not be entitled to payment of any Award hereunder. 9. Rights as a Stockholder. No Employee shall have any rights as a stockholder of the Company with respect to any shares of Common Stock that may be payable hereunder unless and until such shares shall have been issued to such Employee or otherwise credited to an account for the benefit of such Employee. 10. Additional Terms and Conditions of Award. 10.1. Non-Transferability of Award. In accordance with Section 13.5 of the Plan, except as otherwise specifically provided by the Plan or by law, no Award may be transferable in any manner other than by will or the laws of descent and distribution, and any attempt to transfer any such Award shall be void; provided, however, that the foregoing shall not restrict the ability of any Employee to transfer any cash or Common Stock received as part of the payment of the Adjusted Total Award Amount. In accordance with Section 13.5 of the Plan, Awards shall not in any manner be subject to the debts, contracts, liabilities, engagements or torts of any person who shall be entitled to such Award nor shall they be subject to attachment or legal process for or against such person. 10.2. Withholding Taxes. As a condition precedent to the delivery to the Employee of cash or Common Stock hereunder and in accordance with Section 13.4 of the Plan, the Company may deduct from any amount (including any payment of the Adjusted Total Award Amount) payable then or thereafter payable by the Company to the Employee, or may request the Employee to pay to Page 5 of 6 the Company in cash, such amount as the Company may be required, under all applicable federal, state, local or other laws or regulations, to withhold and pay over with respect to the Award. 10.3. Compliance with Applicable Law. Each Award is subject to the condition that if the listing, registration or qualification of the shares of Common Stock subject to the Award upon any securities exchange or under any law, or the consent or approval of any governmental body, or the taking of any other action is necessary or desirable as a condition of, or in connection with, the vesting or delivery of such shares hereunder, such shares may not be delivered, in whole or in part, unless such listing, registration, qualification, consent or approval shall have been effected or obtained. 10.4. Award Subject to the Plan. This Award is subject to the provisions of the Plan, and shall be interpreted in accordance therewith. Page 6 of 6
