(f) Attachment A provides generic examples of the operation of a performance accelerated stock option. 5. TARGETS. (a) FIRST YEAR TARGET. For purposes of this Award Agreement, the Company will have achieved the "First Year Target" if its "Earnings Per Share Growth" (as defined in Section 5(c)) equals or exceeds the Earnings Per Share Growth of the S&P Electric Utilities Index for the fiscal year which includes the Date of Grant, or 20___.

For purposes of this Award Agreement, the Company will have achieved the "Second Year Target" if its Earnings Per Share Growth equals or exceeds the Earnings Per Share Growth of the S&P Electric Utilities Index for the fiscal year immediately following the fiscal year which includes the Date of Grant, or 20___. (c) EARNINGS PER SHARE GROWTH. (i) "Earnings Per Share Growth" for a given fiscal year is the percentage increase, if any, of the Company's earnings per share from continuing operations, on a fully-diluted basis, as of the end of the relevant fiscal year, over the earnings per share from continuing operations, on a fully-diluted basis, as of the end of the immediately preceding fiscal year. Page 3 Performance Accelerated Stock Option (ii) The "Earnings Per Share Growth of the S&P Electric Utilities Index" for a given Fiscal Year is the percentage increase, if any, of the S&P Electric Utilities Index earnings per share, as of the end of the relevant fiscal year, over the earnings per share as of the end of the immediately preceding fiscal year. The Earnings Per Share Growth of the S&P Electric Utilities Index will be determined using the S&P Compustat system. The S&P Electric Utilities Index earnings per share is a weighted average number provided in the S&P Compustat system. If the S&P Compustat system is no longer in use, the Committee will replace it with the most comparable third party data system then in use. If the S&P Electric Utilities Index is discontinued, the S&P comparable replacement index for the sector will be used for computing Earnings Per Share Growth of the S&P Electric Utilities Index. If S&P no longer computes an index for the electric utility sector, the Committee shall select the most comparable index then in use for the sector comparison. In addition, if the sector comparison is no longer representative of the Company's industry or business, the Committee shall replace the index with the most representative index then in use. (iii) All results will be verified by the Company's independent auditors using generally accepted accounting principles, consistently applied. 6. TERM OF OPTION. This Option will be in full force and effect for a period of ten (10) years from the Date of Grant, through and including the close of business of the Company on _________ ___, 20___; however, this Option will terminate earlier upon the occurrence of the events described in this Section 6, with no continuation of vesting.
