Such registration statement has been filed with the Commission not earlier than three years prior to the date hereof, meets the requirements set forth in Rule 415(a)(1)(x) under the 1933 Act and complies in all other respects with said Rule, and as amended at the date it became effective, including the exhibits thereto, is hereinafter called the “Registration Statement”. The base prospectus filed as part of the Registration Statement, in the form in which it has most recently been filed with the Commission on or prior to the date of this Agreement is hereinafter called the “Basic Prospectus”; any preliminary prospectus, including any preliminary prospectus supplement used in connection with the offer and sale of the Notes, filed with the Commission pursuant to Rule 424(b) is hereinafter called the “Preliminary Prospectus”; the form of the final prospectus relating to the Notes filed with the Commission pursuant to Section 3(a) of this Agreement is hereinafter called the “Prospectus”. Any reference herein to the Registration Statement, the Basic Prospectus, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Form S-3 which were filed under the Securities Exchange Act of 1934, as amended (the “1934 Act”), and the rules and regulations of the Commission thereunder (the “1934 Act Regulations”), on or before the date of this Agreement, or the issue date of the Basic Prospectus, any Preliminary Prospectus or the Prospectus, as the case may be; and any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Basic Prospectus, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the filing of any document under the 1934 Act after the date of this Agreement, or the issue date of the Basic Prospectus, any Preliminary Prospectus or the Prospectus, as the case may be, deemed to be incorporated therein by reference. No stop order suspending the effectiveness of the Registration Statement, or any post-effective amendment thereto, or any notice objecting to its use under Rule 401(g)(2), is in effect, and no proceedings for such purpose are pending before or threatened by the Commission.

At or prior to 12:45 p.m., on May 9, 2006 (such time and date, the “Time of Sale”), the Company had prepared the following information (collectively, the “Time of Sale Information”): a Preliminary Prospectus dated May 9, 2006, which shall include the

Since the date of this Agreement, there shall not have occurred a downgrading in the rating assigned to the Notes or any of the Company’s debt securities by any “nationally recognized statistical rating agency,” as that term is defined by the Commission for purposes of Rule 436(g)(2) under the 1933 Act, and no such organization shall have publicly announced that it has under surveillance or review its rating of the Notes or any of the Company’s other debt securities.

(h) Additional Documents. At the Closing Time, counsel for the Underwriters shall have been furnished with such documents and opinions as they may require for the purpose of enabling them to pass upon the issuance and sale of the Notes as herein contemplated, or in order to evidence the accuracy of any of the representations or warranties, or the fulfillment of any of the conditions contained herein; and all proceedings taken by the Company in connection with the issuance and sale of the Notes as herein contemplated shall be satisfactory in form and substance to the Representatives and counsel for the Underwriters.

-14-

(i) Termination of Agreement.

SECTION 7. Indemnification.

(a) Indemnification of Underwriters. The Company agrees to indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included in any Basic Prospectus, Preliminary Prospectus, Issuer Free Writing Prospectus, the Time of Sale Information or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission; provided that (subject to Section 7(d) below) any such settlement is effected with the written consent of the Company (which consent shall not be unreasonably withheld, delayed or conditioned); and

(iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by the Representatives), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment thereto), the Basic Prospectus, any Preliminary

-15-

Prospectus, the Time of Sale Information or the Prospectus (or any amendment or supplement thereto). This indemnity agreement will be in addition to any liability which the Company may otherwise have.

(b) Indemnification of the Company, Directors and Officers. Each Underwriter, severally and not jointly, agrees to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), the Basic Prospectus, any Preliminary Prospectus, the Time of Sale Information or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Underwriter through the Representatives specifically for use in the Registration Statement (or any amendment thereto), the Basic Prospectus, any Preliminary Prospectus, the Time of Sale Information or the Prospectus (or any amendment or supplement thereto).

(c) Actions against Parties, Notification. Promptly after receipt by an indemnified party under this Section 7 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 7, notify the indemnifying party in writing of the commencement thereof, but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party otherwise than under this Section 7. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein, and to the extent that it may elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party; provided, however, that if the defendants (including impleaded parties) in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded after consultation with counsel that there may be legal defenses available to it or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assert such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of its election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 7 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof (other than the reasonable costs of investigation) unless (i) the indemnified party shall have employed separate counsel in connection with the assertion of legal defenses in accordance with the proviso to the next preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (in addition to local counsel) representing the indemnified parties), (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to

-16-

represent the indemnified party within a reasonable time after notice of commencement of the action or (iii) the indemnifying party has authorized the employment of counsel for the indemnified party at the expense of the indemnifying party.

(d) Settlement without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 7(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

SECTION 8. Contribution. If the indemnification provided for in Section 7 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand from the offering of the Notes pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and of the Underwriters on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company on the one hand and the Underwriters on the other hand in connection with the offering of the Notes pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Notes pursuant to this Agreement (before deducting expenses) received by the Company and the total underwriting discount received by the Underwriters, in each case as set forth on the cover of the Prospectus, bear to the aggregate public offering price of the Notes as set forth on such cover.

The relative fault of the Company on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by an Underwriter in writing through the Representatives and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 8.

-17-

The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 8 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 8, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Notes underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 8, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company. The Underwriters’ respective obligations to contribute pursuant to this Section 8 are several in proportion to the principal amount of Notes set forth opposite their respective names in Schedule A hereto and not joint.

SECTION 9. Survival.

The respective indemnities, rights of contribution, representations, warranties and agreements of the Company and the Underwriters contained in this Agreement or made by or on behalf of the Company or the Underwriters pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Notes to the Underwriters and shall remain in full force and effect, regardless of any investigation made by or on behalf of any of them or any of their respective affiliates, officers, directors, employees, representatives, agents or controlling persons.

SECTION 10. Termination of Agreement.

(a) Termination; General. The Representatives may terminate this Agreement, by notice to the Company, at any time at or prior to Closing Time (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Prospectus, any material adverse change (or event involving a prospective change) in the condition, financial or otherwise, or in the results of operations, or business affairs of the Company, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis the

-18-

effect of which is such as to make it, in the judgment of the Representatives, impracticable or inadvisable to offer, sell and deliver the Notes, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the New York Stock Exchange, or if trading generally on the American Stock Exchange or the New York Stock Exchange or in the Nasdaq National Market has been suspended or materially limited (other than to provide for an orderly market), or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, the National Association of Securities Dealers, Inc. or any other governmental authority, or (iv) if a banking moratorium has been declared by either Federal or New York authorities.

(b) Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 5 hereof, and provided, further that Sections 1, 7, 8 and 9 shall survive such termination and remain in full force and effect.

SECTION 11. Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at Closing Time to purchase the Notes which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such principal amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24-hour period, then:

(a) if the aggregate principal amount of the Defaulted Securities does not exceed 10% of the aggregate principal amount of the Notes to be purchased on such date, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

(b) if the aggregate principal amount of the Defaulted Securities exceeds 10% of the aggregate principal amount of the Notes to be purchased on such date, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section shall relieve any underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement either (i) the Representatives or (ii) the Company shall have the right to postpone the Closing Time for a period not exceeding seven days in order to effect any required changes in the Registration Statement, the Time of Sale Information or Prospectus or in any other documents or arrangements. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 11.

(v) The Registration Statement, the Preliminary Prospectus, the Prospectus, excluding in each case the documents incorporated by reference therein, and each amendment or supplement to the Registration Statement and the Prospectus, excluding in each case the documents incorporated by reference therein and the Statements of Eligibility on Form T-1 of the applicable trustees, as of their respective effective or issue dates (other than the financial statements and supporting schedules included therein or omitted therefrom, as to which we express no opinion) complied as to form in all material respects with the requirements of the 1933 Act and the 1933 Act Regulations and the 1939 Act.

(vi) The documents incorporated by reference in the Time of Sale Information and the Prospectus (other than the financial statements and supporting schedules included therein or omitted therefrom, and the Statements of Eligibility on Form T-1 of the applicable trustees, as to which we express no opinion), when they became effective or were filed with the Commission, or as subsequently amended prior to the date of the Agreement, as the case may be, complied as to form at the time of such effectiveness or filing in all material respects with the requirements of the 1934 Act and the 1934 Act Regulations.

(vii) No filing, registration or qualification with, or authorization, approval consent, license, order, or decree of, any court or governmental authority or agency, domestic or foreign (other than under the 1933 Act and the 1933 Act Regulations and the 1939 Act, which have been obtained or made, or as may be required under the securities or blue sky laws of the various states, as to which we express no opinion) is necessary or required in connection with the due authorization, execution and delivery of this Agreement or the Indenture or for the offering, issuance, sale or delivery of the Notes.

(x) The Indenture has been duly qualified under the 1939 Act.

(xi) The statements made in the Prospectus under the captions “Description of the Notes” and “Description of Debt Securities of Tampa Electric Company,” insofar as such statements purport to constitute a summary of the terms of any of the Transaction Documents, constitute accurate summaries thereof in all material respects.

We have participated in conferences with officers and other representatives of the Company, representatives of the Underwriters and representatives of the independent public accountants for the Company at which conferences the contents of the Registration Statement, Time of Sale Information and the Prospectus and related matters were discussed and, although we have not independently verified, are not passing upon and do not assume any responsibility

for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Time of Sale Information or the Prospectus (except as otherwise indicated above), we advise you that, on the basis of the foregoing, no facts have come to our attention that lead us to believe that (i) the Registration Statement or any amendment thereto, at the time such Registration Statement or any such amendment became effective (including the information deemed to be part of the Registration Statement at the time it became effective pursuant to Rule 430A, 430B or 430C under the 1933 Act), contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) the Time of Sale Information, taken as a whole, at the Time of Sale contained any untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or (iii) the Prospectus or any amendment or supplement thereto, as of its date or as of the date hereof, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading (it being understood that we express no view with respect to the Forms T-1 or the financial statements, including the notes thereto, or any other financial data found in or derived from the internal accounting and other records of the Company set forth or referred to in the Registration Statement, the Time of Sale Information or the Prospectus).

Exhibit A-2

FORM OF OPINION OF SHEILA M. MCDEVITT

GENERAL COUNSEL, TAMPA ELECTRIC COMPANY

TO BE DELIVERED PURSUANT TO

SECTION 6(b)(ii)

Capitalized terms used herein shall have the same definitions as set forth in the underwriting agreement (the “Agreement”) to which this Exhibit A-2 is attached.

(i) The Company is validly existing as a corporation in good standing under the laws of the State of Florida, with corporate power and authority to own, lease and operate its properties and to conduct its business as described in the Prospectus, as amended and supplemented, and to enter into and perform its obligations under this Agreement and the Indenture.

(ii) The Agreement has been duly authorized, executed and delivered by the Company.

I, or attorneys under my supervision, have participated in conferences with officers and other representatives of the Company, representatives of the Underwriters and representatives of the independent public accountants for the Company at which conferences the contents of the Registration Statement, the Time of Sale Information and the Prospectus and related matters were discussed and, although I have not independently verified, am not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Time of Sale Information or the Prospectus (except as otherwise indicated above), I advise you that, on the basis of the foregoing, no facts have come to my attention that lead me to believe that (i) the Registration Statement or any amendment thereto, at the time such Registration Statement or any such amendment became effective (including the information deemed to be part of the Registration Statement at the time it became effective pursuant to Rule 430A, 430B or 430C under the 1933 Act), contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) the Time of Sale Information, taken as a whole, at the Time of Sale contained any untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or (iii) the Prospectus or any amendment or supplement thereto, as of its date or as of the date hereof, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not

misleading (it being understood that I express no view with respect to the Forms T-1 or the financial statements, including the notes thereto, or any other financial data found in or derived from the internal accounting and other records of the Company set forth or referred to in the Registration Statement, the Time of Sale Information or the Prospectus).
