plus, in either of the above cases, accrued and unpaid interest thereon to the redemption date.

(b) The Company will mail a notice of redemption at least 30 days but no more than 60 days before the redemption date to each Holder of 2017 Notes to be redeemed.

“Independent Investment Banker” means Citigroup Global Markets Inc. or X.X. Xxxxxx Securities Inc. or any of their respective successors as designated by the Company, or if all of those firms are unwilling or unable to serve as such, an independent investment and banking institution of national standing appointed by the Company

(i) Citigroup Global Markets Inc. or X.X. Xxxxxx Securities Inc. or their respective successors; provided that, if any such Reference Treasury Dealer ceases to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), the Company will substitute another Primary Treasury Dealer; and

(ii) up to three other Primary Treasury Dealers selected by the Company.

“Treasury Rate” means, as of any redemption date, the rate per annum equal to the semiannual equivalent yield to maturity (computed as of the second business day immediately preceding that redemption date) of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for that redemption date.

acquire or dispose of any assets of a pension or welfare plan, which insurance company has as of the last day of its most recent fiscal year, net worth in excess of $1,000,000 and which is subject to supervision and examination by a state authority having supervision over insurance companies, and, in any case, such investment adviser, bank, or insurance company is otherwise a qualified professional asset manager (“QPAM”), as such term is used in Prohibited Transaction Class Exemption 84-14 issued by the Department of Labor, and the assets of such plan when combined with the assets of other plans established or maintained by the same employer (or affiliate thereof) or employee organization and managed by the QPAM, do not represent more than 20% of the total client assets managed by the QPAM at the time of the transaction, and the other applicable conditions of such exemption are otherwise satisfied;

(vii) to the extent such purchase will not otherwise give rise to a transaction described in Section 406 of ERISA or Section 4975(c)(1) of the Code for which a statutory or administrative exemption is unavailable.

Section 503. Reports by the Guarantor

So long as any of the Notes are Restricted Securities, the Guarantor will, during any period in which it is not subject to Sections 13 or 15(d) of the Exchange Act or it is not exempt from such reporting requirements pursuant to and in compliance with Rule 12g3-2(b) under the Exchange Act, provide to each Holder of Notes and to each prospective purchaser (as designated by such Holder) of Notes, upon the request of such Holder or prospective purchaser, any information required to be provided by Rule 144A(d)(4) under the Securities Act.

7.20% Notes Due 2011

This Note is one of a duly authorized series of securities of the Company (herein called the “Notes”), issued and to be issued under an Indenture dated as of December 21, 2007, as supplemented by the First Supplemental Indenture, dated as of December 21, 2007 (as such has been or shall be amended or supplemented, the “Indenture”), among the Company, TECO Energy, Inc. (the “Guarantor”) and The Bank of New York Trust Company, N.A., as trustee (the “Trustee”, which term includes any successor Trustee under the Indenture), to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. This Note is one of the securities of the series designated on the face hereof.

DEFINITIONS

The following terms, as used herein, have the following meanings unless the context or use clearly indicates another or different meaning or intent:

“Adjusted Treasury Rate” means, with respect to any redemption date:

(i)

the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published Federal Reserve Statistical Release designated “H.15” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the Remaining Life, as defined below, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue will be determined and the Adjusted Treasury Rate will be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month); or

(ii)

if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date.

The Adjusted Treasury Rate will be calculated on the third Business Day preceding the redemption date.

“Business Day” shall mean any day other than a Saturday or Sunday that is neither a legal holiday nor a day on which banking institutions are authorized or obligated by law or executive order to close in the City of New York.

“Comparable Treasury Price” means (1) the average of five Reference Treasury Dealer Quotations for the Redemption Date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if an Independent Investment Banker obtains fewer than five such Reference Treasury Dealer Quotations, the average of all such quotations.

“Depositary” shall mean The Depository Trust Company or any successor depositary.

“Independent Investment Banker” means X.X. Xxxxxx Securities Inc. and its successors, or if that firm is unwilling or unable to serve as such, an independent investment and banking institution of national standing appointed by the Company.

“Interest Payment Date” shall mean the date on which interest on this Note is paid, which date(s) are set forth on the face of this Note.

“Reference Treasury Dealer” means:

(i) X.X. Xxxxxx Securities Inc. and its successors; provided that, if X.X. Xxxxxx Securities Inc. ceases to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), the Company will substitute another Primary Treasury Dealer; and

(ii) up to four other Primary Treasury Dealers selected by the Company.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by an Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to an Independent Investment Banker at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date.

INTEREST RATE

This Note will bear interest at the rate per annum (computed based on a 360-day year consisting of twelve 30-day months) identified on the face of this Note. Except for the effect of any adjustment in the Interest Payment Date as provided in the following sentence, the amount of interest payable for any period shorter than a full six-month period for which interest is computed, will be computed on the basis of the actual number of days elapsed in such a 180-day period. If any Interest Payment Date would otherwise be a day that is not a Business Day, the payment required to be made on such Interest Payment Date will be postponed to the next succeeding Business Day, and no interest will accrue on such payment for the period from and after such Interest Payment Date to the date of such payment on the next succeeding Business Day, except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on such Interest Payment Date.

OPTIONAL REDEMPTION

The Notes are subject to redemption, in whole or in part, at any time, and at the option of the Company, at a redemption price equal to the greater of:

(i)

100% of the principal amount of the Notes then outstanding to be redeemed, or

(ii)

the sum of the present values of the remaining scheduled payments of principal and interest on the Notes then outstanding to be redeemed (not including any portion of such payments of interest accrued as of the Redemption Date) discounted to the Redemption Date on a semiannual basis (computed based on a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate, plus 25 basis points (0.25%), as calculated by an Independent Investment Banker,

plus, in either of the above cases, accrued and unpaid interest thereon to the Redemption Date (the “Redemption Price”).

The Company will mail a notice of redemption at least 30 days but no more than 60 days before the Redemption Date to each Holder of the Notes to be redeemed. If the Company elects to partially redeem the Notes, the Trustee will select in a fair and appropriate manner the Notes to be redeemed.

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Notes or portions thereof called for redemption.

The Notes are not entitled to the benefit of any sinking fund or analogous provision.

TRANSFER OR EXCHANGE

As provided in the Indenture and subject to certain limitations herein and therein set forth, the transfer of this Note is registerable in the Security Register, upon surrender of this Note for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Note are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Notes of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. To the extent permitted by law, any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of (and premium, if any) and interest on this Note at the times, place and rate, and in the coin or currency, herein prescribed.

DEFINITIONS

The following terms, as used herein, have the following meanings unless the context or use clearly indicates another or different meaning or intent:

“Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Notes to be redeemed that would be used, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Notes; provided, however, that if the remaining term of the Notes to be redeemed is less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year will be used.

“Depositary” shall mean The Depository Trust Company or any successor depositary.

“Independent Investment Banker” means any of Citigroup Global Markets Inc. or X.X. Xxxxxx Securities Inc. or any of their respective successors, as designated by the Company, or if all of those firms are unwilling or unable to serve as such, an independent investment and banking institution of national standing appointed by the Company.

“Interest Payment Date” shall mean the date on which interest on this Note is paid, which date(s) are set forth on the face of this Note.

“Reference Treasury Dealer” means:

(i) Citigroup Global Markets Inc. or X.X. Xxxxxx Securities Inc., and each of their respective successors; provided that, if any such Reference Treasury Dealer ceases to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), the Company will substitute another Primary Treasury Dealer; and

(ii) up to three other Primary Treasury Dealers selected by the Company

INTEREST RATE

OPTIONAL REDEMPTION

The Notes are subject to redemption, in whole or in part, at any time, and at the option of the Company, at a redemption price equal to the greater of:

(v)

100% of the principal amount of the Notes then outstanding to be redeemed, or

(vi)

the sum of the present values of the remaining scheduled payments of principal and interest on the Notes then outstanding to be redeemed (not including any portion of such payments of interest accrued as of the Redemption Date) discounted to the Redemption Date on a semiannual basis (computed based on a 360-day year consisting of twelve 30-day months) at the Treasury Rate, plus 50 basis points (0.50%), as calculated by an Independent Investment Banker,

plus, in either of the above cases, accrued and unpaid interest thereon to the Redemption Date (the “Redemption Price”).

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Notes or portions thereof called for redemption.

The Notes are not entitled to the benefit of any sinking fund or analogous provision.
