Performance Shares Agreement

TECO Energy, Inc. (the “Company”) and _____________________________________ (the “Grantee”) have entered into this Performance Shares Agreement (the “Agreement”) dated April 28, 2004 under the Company’s 2004 Equity Incentive Plan (the “Plan”). Capitalized terms not otherwise defined herein have the meanings given to them in the Plan.

1. Grant of Performance Shares. Pursuant to the Plan and subject to the terms and conditions set forth in this Agreement, the Company hereby grants, issues and delivers to the Grantee ___________________ shares (“Number of Restricted Performance Shares”) of its Common Stock (the “Restricted Performance Shares”) as of the date of this Agreement and will grant, issue and deliver to the Grantee the Performance Reward Percentage of ___________________ shares (“Number of Additional Performance Shares”) of its Common Stock (the “Additional Performance Shares”) no later than 30 days after the end of the Performance Period.

The “Performance Period” is the period beginning April 1, 2004 and ending on the date determined under Section 3.

“Total Shareholder Return” is the amount obtained by dividing (1) the sum of (a) the amount of dividends with respect to the Performance Period, assuming dividend reinvestment, and (b) the difference between the share price at the end and beginning of the Performance Period, by (2) the closing share price at the beginning of the Performance Period, with the share price in each case being determined by using the average closing price during the 20 trading days preceeding (and inclusive of) the date of determination The share price shall be equitably adjusted for stock splits and other similar corporate actions affecting the stock.

The “Performance Measurement” is a measurement of the relative performance of the Company’s Common Stock calculated by assuming the Company was included in the Dow Jones U.S. Electrical Utilities Index-All Regions (ELC) and then ordering the ELC (as constituted at the end of the Performance Period) by Total Shareholder Return from highest to lowest.

The “Performance Reward Percentage” is the percentage shown in column B corresponding to the Performance Measurement in column A, with interpolation of the percentages in column B in proportion to the corresponding placement in column A. The Performance Reward Percentage for Restricted Performance Shares shall not exceed 100%, and the Performance Reward Percentage for Additional Performance Shares shall be the amount, if any, in excess of 100%.

2. Restrictions on Restricted Performance Shares. Until the restrictions terminate under Section 3, unless otherwise determined by the Committee:

(a) the Restricted Performance Shares may not be sold, assigned, pledged or transferred by the Grantee; and

(b) all Restricted Performance Shares will be forfeited and returned to the Company and the Grantee will cease to have any right to receive any additional Performance Shares, if the Grantee ceases to be an employee of the Company or any business entity in which the Company owns directly or indirectly 50% or more of the total voting power or has a significant financial interest as determined by the Committee (an “Affiliate”).

3. End of Performance Period and Termination of Restrictions. The Performance Period will end, the restrictions on the Performance Reward Percentage of the Number of Restricted Performance Shares will terminate, the remainder of the Restricted Performance Shares will be forfeited and returned to the Company, and the Grantee will cease to have any right to receive any Additional Performance Shares in excess of the Performance Reward Percentage of the Number of Additional Performance Shares, on the earliest to occur of the following events:

(a) the Grantee’s death;

(b) the termination of Grantee’s employment with the Company or any Affiliate because of a disability that would entitle the Grantee to benefits under the long-term disability benefits program of the Company for which the Grantee is eligible, as determined by the Committee;

(c) the termination by the Company or any Affiliate of Grantee’s employment other than for Cause as determined by the Committee. “Cause” means (i) willful and continued failure of the Grantee to substantially perform his duties with the Company or such Affiliate (other than by reason of physical or mental illness) after written demand specifically identifying such failure is given to the Grantee by the Company, or (ii) willful conduct by the Grantee that is demonstrably and materially injurious to the Company. For purposes of this subsection, “willful” conduct requires an act, or failure to act, that is not in good faith and that is without reasonable belief that the action or omission was in the best interest of the Company or the Affiliate;
