Dear Ladies and Gentlemen:

The undersigned Florida Power Corporation d/b/a Progress Energy Florida, Inc. (the “Company”) hereby confirms its agreement with each of the several Underwriters hereinafter named as follows:

1. Underwriters and Representative. The term “Underwriters” as used in this Underwriting Agreement (the “Agreement”) shall be deemed to mean the firm or the several firms named in Schedule I hereto and any underwriter substituted as provided in paragraph 6, and the term “Underwriter” shall be deemed to mean any one of such Underwriters.

If the firm or firms listed as Representatives in Schedule I hereto (individually and collectively, the “Representative”) are the only firm or firms serving as underwriters, then the terms “Underwriters” and “Representative,” as used herein, shall each be deemed to refer to such firm or firms. Each Representative represents jointly and severally that they have been authorized by the Underwriters to execute this Agreement on their behalf and to act for them in the manner herein provided. All obligations of the Underwriters hereunder are several and not joint. If more than one firm is named as Representative in Schedule I hereto, any action under or in respect of this Agreement may be taken by such firms jointly as the Representative, or by one of the firms acting on behalf of the Representative, and such action will be binding upon all the Underwriters.

2. Description of Securities. The Company proposes to issue and sell its First Mortgage Bonds of the designation, with the terms and in the amount specified in Schedule I hereto (the “Securities”) under its Indenture, dated as of January 1, 1944, with The Bank of New York Mellon, as successor trustee (the “Trustee”), as supplemented by the Seventh, Eighth, Sixteenth, Twenty-Ninth, Thirty-Eighth and the Fortieth through the Forty-Ninth Supplemental Indentures, and as it will be further supplemented by the Fiftieth Supplemental Indenture (the “Fiftieth Supplemental Indenture”) relating to the Securities, in substantially the form heretofore delivered to the Representative, said Indenture as supplemented by the Seventh, Eighth, Sixteenth, Twenty-Ninth, Thirty-Eighth and the Fortieth through the Forty-Ninth Supplemental Indentures, and to be supplemented by the Fiftieth Supplemental Indenture being hereinafter referred to as the “Mortgage.”

3. Representations and Warranties of the Company. The Company represents and warrants to each of the Underwriters that:

(a) The Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3, as amended (No. 333-155418-01) (the “Registration Statement”), under the Securities Act of 1933, as amended (the “Securities Act”), for the registration of an indeterminate amount of First Mortgage Bonds, Debt Securities and Preferred Stock. The Registration Statement became effective upon filing with the Commission on November 18, 2008. The term “Registration Statement” shall be deemed to include all amendments made by the Company prior to the Applicable Time (defined below) and all documents filed by the Company with the Commission and incorporated by reference therein (the “Incorporated Documents”). The base prospectus filed by the Company as part of the Registration Statement, in the form in which it has most recently been filed with the Commission prior to the date of this Agreement, is hereinafter called the “Basic Prospectus.” The Basic Prospectus, as supplemented by a preliminary prospectus supplement, dated August 15, 2011, relating to the Securities, and all prior amendments or supplements thereto made by the Company (other than amendments or supplements relating to the securities of the Company other than the Securities), including the Incorporated Documents, is hereinafter referred to as the “Preliminary Prospectus.” The Preliminary Prospectus, as amended and supplemented, including the Incorporated Documents, at or immediately prior to the Applicable Time (as defined below) is hereinafter called the “Pricing Prospectus.” The Basic Prospectus, as it is to be supplemented by a prospectus supplement, dated on the date hereof, substantially in the form delivered to the Representative prior to the execution hereof, relating to the Securities (the “Prospectus Supplement”) and all prior amendments or supplements thereto (other than amendments or supplements relating to securities of the Company other than the Securities), including the Incorporated Documents, is hereinafter referred to as the “Prospectus.” Any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement or the Prospectus shall be deemed to refer to and include any post-effective amendment to the Registration Statement, any prospectus supplement relating to the Securities filed with the Commission pursuant to Rule 424(b) under the Securities Act and the filing of any document under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), deemed to be incorporated therein after the Applicable Time and prior to the termination of the offering of the Securities by the Underwriters; and any references herein to the terms “Registration Statement” or “Prospectus” at a date after the filing of the Prospectus Supplement shall be deemed to refer to the Registration Statement or the Prospectus, as the case may be, as each may be amended or supplemented prior to such date.

For purposes of this Agreement, the “Applicable Time” is 1:30 p.m. (New York City time) on the date of this Agreement; the documents listed in Schedule II hereto, taken together, as of the Applicable Time are collectively referred to as the “Pricing Disclosure Package;” and all references to the Registration Statement, the Pricing Disclosure Package or the Prospectus or any amendment or supplement thereto shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system (“▇▇▇▇▇”).

(b) The Registration Statement, at each time and date it became, or is deemed to have become, effective, complied, and the Registration Statement, the Prospectus and the Mortgage, as of the date hereof and at the Closing Date (as defined herein), will comply, in all material respects, with the applicable provisions of the Securities Act and the Trust Indenture Act of 1939, as amended (the “1939 Act”), and the applicable instructions, rules and regulations of the Commission thereunder; the Registration Statement, at each time and date it became, or is deemed to have become, effective, did not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; the Pricing Disclosure Package as of the Applicable Time did not contain an untrue statement of a material fact or omit 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; and the Prospectus, as of its date and at the Closing Date, will not contain an untrue statement of a material fact or omit 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; provided, however, that the foregoing representations and warranties in this subparagraph (b) shall not apply to statements or omissions made in reliance upon and in conformity with the information furnished herein or in writing to the Company by the Representative or by or on behalf of any Underwriter through the Representative expressly for use in the Prospectus or to any statements in or omissions from the Statement of Eligibility (“Form T-1”) of the Trustee. The Incorporated Documents, at the time they were each filed with the Commission, complied in all material respects with the applicable requirements of the Exchange Act and the instructions, rules and regulations of the Commission thereunder, and any documents so filed and incorporated by reference subsequent to the date hereof and prior to the termination of the offering of the Securities by the Underwriters will, at the time they are each filed with the Commission, comply in all material respects with the requirements of the Exchange Act and the instructions, rules and regulations of the Commission thereunder; and, when read together with the Registration Statement, the Pricing Disclosure Package and the Prospectus, none of such documents included or includes or will include any untrue statement of a material fact or omitted or omits or will omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(f) The historical financial statements incorporated by reference in the Registration Statement, the Pricing Prospectus and the Prospectus present fairly the financial condition and operations of the Company at the respective dates or for the respective periods to which they apply; such financial statements have been prepared, in each case, in accordance with generally accepted accounting principles consistently applied throughout the periods involved, except that the quarterly financial statements, if any, incorporated by reference from any Quarterly Reports on Form 10-Q contain condensed footnotes prepared in accordance with applicable Exchange Act rules and regulations; and Deloitte & Touche LLP, which has audited the financial statements, is an independent registered public accounting firm as required by the Securities Act or the Exchange Act and the rules and regulations of the Commission thereunder.

(g) Except as reflected in, or contemplated by, the Registration Statement and the Pricing Disclosure Package, since the respective dates as of which information is given in the Registration Statement and the Pricing Prospectus, and prior to the Closing Date, (i) there has not been any material adverse change in the business, properties, results of operations or financial condition of the Company, (ii) there has not been any material transaction entered into by the Company other than transactions contemplated by the Registration Statement and the Pricing Prospectus or transactions arising in the ordinary course of business and (iii) the Company has no material contingent obligation that is not disclosed in the Pricing Disclosure Package and the Prospectus that could likely result in a material adverse change in the business, properties, results of operations or financial condition of the Company.

of any government or governmental authority or agency or court having jurisdiction over the Company or any of its assets, properties or operations that, in the case of any such breach or default, would have a material adverse effect on the business, properties, results of operations or financial condition of the Company.

Each non-defaulting Underwriter shall do so on a pro-rata basis according to the amounts set forth opposite the name of such non-defaulting Underwriter in Schedule I hereto, and such non-defaulting Underwriters shall have the right, within 24 hours of receipt of such notice, either to take up and pay for (in such proportion as may be agreed upon among them), or to substitute another Underwriter or Underwriters, satisfactory to the Company, to take up and pay for, the remaining principal amount of the Securities that the defaulting Underwriter or Underwriters agreed but failed to purchase. If any unpurchased Securities still remain, then the Company or the Representative shall be entitled to an additional period of 24 hours within which to procure another party or parties, members of the Financial Industry Regulatory Authority, Inc. (the “Authority”) (or if not members of the Authority, who are not eligible for membership in the Authority and who agree (i) to make no sales within the United States, its territories or its possessions or to persons who are citizens thereof or residents therein and (ii) in making sales to comply with the Authority’s Conduct Rules) and satisfactory to the Company, to purchase or agree to purchase such unpurchased Securities on the terms herein set forth. In any such case, either the Representative or the Company shall have the right to postpone the Closing Date for a period not to exceed three full business days from the date agreed upon in accordance with this paragraph 6, in order that the necessary changes in the Registration Statement and Prospectus and any other documents and arrangements may be effected. If (i) neither the non-defaulting Underwriters nor the Company has arranged for the purchase of such unpurchased Securities by another party or parties as above provided and (ii) the Company and the non-defaulting Underwriters have not mutually agreed to offer and sell the Securities other than the unpurchased Securities, then this Agreement shall terminate without any liability on the part of the Company or any Underwriter (other than an Underwriter that shall have failed or refused, in accordance with the terms hereof, to purchase and pay for the principal amount of the Securities that such Underwriter has agreed to purchase as provided in paragraph 4 hereof), except as otherwise provided in paragraph 7 and paragraph 8 hereof.

7. Covenants of the Company. The Company covenants with each Underwriter that:

(a) As soon as reasonably possible after the execution and delivery of this Agreement, the Company will file the Prospectus with the Commission pursuant to Rule 424 under the Securities Act (“Rule 424”), setting forth, among other things, the necessary information with respect to the terms of offering of the Securities and make

any other required filings pursuant to Rule 433 under the Securities Act. Upon request, the Company will promptly deliver to the Representative and to counsel for the Underwriters, to the extent not previously delivered, one fully executed copy or one conformed copy, certified by an officer of the Company, of the Registration Statement, as originally filed, and of all amendments thereto, if any, heretofore or hereafter made (other than those relating solely to securities of the Company other than the Securities), including any post-effective amendment (in each case including all exhibits filed therewith and all documents incorporated therein not previously furnished to the Representative), including signed copies of each consent and certificate included therein or filed as an exhibit thereto, and will deliver to the Representative for distribution to the Underwriters as many conformed copies of the foregoing (excluding the exhibits, but including all documents incorporated therein) as the Representative may reasonably request. The Company will also send to the Underwriters as soon as practicable after the date of this Agreement and thereafter from time to time as many copies of the Prospectus and the Preliminary Prospectus as the Representative may reasonably request for the purposes required by the Securities Act.

(b) During such period (not exceeding nine months) after the commencement of the offering of the Securities as the Underwriters may be required by law to deliver a Prospectus (or in lieu thereof, the notice referred to in Rule 173(a) under the Securities Act), if any event relating to or affecting the Company, or of which the Company shall be advised in writing by the Representative shall occur, which in the Company’s reasonable opinion (after consultation with counsel for the Representative) should be set forth in a supplement to or an amendment of the Prospectus in order to make the Prospectus not misleading in the light of the circumstances when it is delivered to a purchaser (or in lieu thereof, the notice referred to in Rule 173(a) under the Securities Act), or if it is necessary to amend the Prospectus to comply with the Securities Act, the Company will forthwith at its expense prepare, file with the Commission and furnish to the Underwriters and dealers named by the Representative a reasonable number of copies of a supplement or supplements or an amendment or amendments to the Prospectus that will supplement or amend the Prospectus so that as supplemented or amended it will comply with the Securities Act and will not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances when the Prospectus is delivered to a purchaser, not misleading. In case any Underwriter is required to deliver a Prospectus (or in lieu thereof, the notice referred to in Rule 173(a) under the Securities Act) after the expiration of nine months after the commencement of the offering of the Securities, the Company, upon the request of the Representative, will furnish to the Representative, at the expense of such Underwriter, a reasonable quantity of a supplemented or amended prospectus, or supplements or amendments to the Prospectus, complying with Section 10(a) of the Securities Act.

(c) The Company will make generally available to its security holders, as soon as reasonably practicable, but in any event not later than 16 months after the end of the fiscal quarter in which the filing of the Prospectus pursuant to Rule 424 occurs, an earnings statement (in form complying with the provisions of Section 11(a) of the Securities Act, which need not be certified by independent public accountants) covering a period of twelve months beginning not later than the first day of the Company’s fiscal quarter next following the filing of the Prospectus pursuant to Rule 424.

(d) The Company will use commercially reasonable efforts promptly to do and perform all things to be done and performed by it hereunder prior to the Closing Date and to satisfy all conditions precedent to the delivery by it of the Securities.

(e) As soon as reasonably possible after the Closing Date, the Company will cause the Fiftieth Supplemental Indenture to be recorded (i) in all recording offices in the State of Florida in which the property intended to be subject to the lien of the Mortgage is located and (ii) with the Surface Transportation Board.

(f) The Company will advise the Representative, or the Representative’s counsel, promptly of the filing of the Prospectus pursuant to Rule 424 and of any amendment or supplement to the Prospectus or Registration Statement or of official notice of institution of proceedings for, or the entry of, a stop order suspending the effectiveness of the Registration Statement and, if such a stop order should be entered, use commercially reasonable efforts to obtain the prompt removal thereof.

(g) The Company will use commercially reasonable efforts to qualify the Securities, as may be required, for offer and sale under the Blue Sky or legal investment laws of such jurisdictions as the Representative may designate and will file and make in each year such statements or reports as are or may be reasonably required by the laws of such jurisdictions; provided, however, that the Company shall not be required to qualify as a foreign corporation or dealer in securities, or to file any general consents to service of process, under the laws of any jurisdiction.

(h) Prior to the termination of the offering of the Securities, the Company will not file any amendment to the Registration Statement or supplement to the Pricing Prospectus or the Prospectus which shall not have previously been furnished to the Representative or of which the Representative shall not previously have been advised or to which the Representative shall reasonably object in writing and which has not been approved by the Representative or its counsel, acting on behalf of the Underwriters.

(i) If at any time when Securities remain unsold by the Underwriters, the Company receives from the Commission a notice pursuant to Rule 401(g)(2) of the Securities Act or otherwise ceases to be eligible to use the automatic shelf registration statement form, the Company will (i) promptly notify the Representative, (ii) promptly file a new registration statement or post-effective amendment on the proper form relating to the Securities, in a form reasonably satisfactory to the Representative, or take such other action, after consultation with counsel, as the Company believes is appropriate, (iii) use commercially reasonable efforts to cause any new registration statement or post-effective amendment that may be filed pursuant to clause (ii) above, to be declared effective and (iv) promptly notify the Representative of any such effectiveness. The Company will take all other commercially reasonable action as it deems appropriate to permit the public offering and sale of the Securities to continue as contemplated in the registration statement that was subject to the Rule 401(g)(2) notice or for which the

Company has otherwise become ineligible. References herein to the Registration Statement shall include such new registration statement or post-effective amendment, as the case may be.

The Company will pay all expenses incident to the performance of its obligations under this Agreement, including (i) the printing and filing of the Registration Statement and the printing of this Agreement, (ii) the delivery of the Securities to the Underwriters, (iii) the fees and disbursements of the Company’s counsel and accountants, (iv) the expenses in connection with the qualification of the Securities under securities laws in accordance with the provisions of paragraph 7(g) hereof, including filing fees and the fees and disbursements of counsel for the Underwriters in connection therewith, such fees and disbursements not to exceed $7,500, (v) the printing and delivery to the Underwriters of copies of the Registration Statement and all amendments thereto, the Preliminary Prospectus, any Permitted Free Writing Prospectus and the Prospectus and any amendments or supplements thereto, (vi) the printing and delivery to the Underwriters of copies of the Blue Sky Survey and (vii) the preparation, execution, filing and recording by the Company of the Fiftieth Supplemental Indenture (such filing and recordation to be promptly made after execution and delivery thereof to the Trustee under the Mortgage in the counties in which the mortgaged property of the Company is located); and the Company will pay all taxes, if any (but not including any transfer taxes), on the issue of the Securities and the filing and recordation of the Fiftieth Supplemental Indenture. The fees and disbursements of Underwriters’ counsel shall be paid by the Underwriters (subject, however, to the provisions of this paragraph 8 requiring payment by the Company of fees and disbursements not to exceed $7,500); provided, however, that if this Agreement is terminated in accordance with the provisions of paragraph 9, 10 or 12 hereof, the Company shall reimburse the Representative for the account of the Underwriters for the fees and disbursements of Underwriters’ counsel. The Company shall not be required to pay any amount for any expenses of the Representative or of any other of the Underwriters except as provided in paragraph 7 hereof and in this paragraph 8. The Company shall not in any event be liable to any of the Underwriters for damages on account of the loss of anticipated profit.

9. Conditions of Underwriters’ Obligations. The several obligations of the Underwriters to purchase and pay for the Securities shall be subject to the accuracy of the representations and warranties on the part of the Company as of the date hereof and the Closing Date, to the performance by the Company of its obligations to be performed hereunder prior to the Closing Date, and to the following further conditions:

(a) No stop order suspending the effectiveness of the Registration Statement shall be in effect on the Closing Date and no proceedings for that purpose shall be pending before, or, to the Company’s knowledge, threatened by, the Commission on the Closing Date and no notice from the Commission pursuant to Rule 401(g)(2) of the Securities Act shall have been received by the Company. The Representative shall have received, prior to payment for the Securities, a certificate dated the Closing Date and signed by the Chairman, President, Treasurer or a Vice President of the Company to the effect that no such stop order is in effect, that no proceedings for such purpose are pending before or, to the knowledge of the Company, threatened by the Commission and no notice from the Commission pursuant to Rule 401(g)(2) of the Securities Act shall have been received by the Company.

(b) At the time of execution of this Agreement, or such later date as shall have been consented to by the Representative, there shall have been issued, and on the Closing Date there shall be in full force and effect, an order of the Florida Public Service Commission authorizing the issuance and sale of the Securities, which shall not contain any provision unacceptable to the Representative by reason of its being materially adverse to the Company (it being understood that no such order in effect on the date of this Agreement and heretofore furnished to the Representative or counsel for the Underwriters contains any such unacceptable provision).

(c) At the Closing Date, the Representative shall receive a favorable opinion, and with respect to clauses (iv) and (v), assurance statement, satisfactory in form and substance to counsel for the Underwriters, from Smith, Anderson, Blount, Dorsett, ▇▇▇▇▇▇▇▇ & ▇▇▇▇▇▇▇▇, L.L.P., counsel for the Company, to the effect that:

(i) The Mortgage has been duly qualified under the 1939 Act;

(ii) The statements made in the Basic Prospectus under the caption “Description of First Mortgage Bonds” and in the Pricing Prospectus under the caption “Description of Bonds,” insofar as they purport to constitute summaries of the documents referred to therein, are accurate summaries in all material respects;

(iii) The statements made in the Pricing Prospectus and the Prospectus under the caption “Material U.S. Federal Tax Considerations,” insofar as they purport to constitute summaries of matters of U.S. federal income tax law or legal conclusions with respect thereto, are accurate and complete in all material respects;

(iv) The Registration Statement, at each time and date it was declared, or is deemed to have become, effective by the Commission, and the Pricing Disclosure Package and the Prospectus, as of their respective dates (except as to the financial statements and schedules and notes thereto or other financial, numerical, accounting, statistical or quantitative information (or the assumptions with respect thereto) included or incorporated by reference therein or excluded therefrom and that part of the Registration Statement that constitutes the Statement of Eligibility on Form T-1 upon which such assurance statement need not pass), appeared on their face to respond in all material respects to the requirements of the Securities Act and the 1939 Act and the applicable instructions, rules and regulations of the Commission thereunder; and the documents or portions thereof filed with the Commission pursuant to the Exchange Act and deemed to be incorporated by reference in the Registration Statement, the Preliminary Prospectus, the Pricing Prospectus and the Prospectus pursuant to Item 12 of Form S-3 (except as to financial statements and schedules and notes thereto or other financial, numerical, accounting, statistical or quantitative information (or the assumptions with respect thereto) included or incorporated by reference therein or excluded therefrom and that part of the Registration Statement that constitutes the Statement of Eligibility on Form T-1 upon which such assurance statement need not pass), at the time they were filed

with the Commission, appeared on their face to respond in all material respects to the requirements of the Exchange Act and the applicable instructions, rules and regulations of the Commission thereunder; the Registration Statement was effective upon filing with the Commission under the Securities Act and, such counsel has been verbally advised by the staff of the Commission that no stop order suspending the effectiveness of the Registration Statement has been issued and not withdrawn, and no proceedings for a stop order with respect thereto have been instituted by the Commission; and

(v) Nothing has come to the attention of said counsel that would lead them to believe that the Registration Statement, at each time and date it was declared, or is deemed to have become, effective by the Commission, 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; and nothing has come to the attention of said counsel that would lead them to believe that (x) the Pricing Disclosure Package, as of the Applicable Time, included an untrue statement of a material fact or omitted 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 or (y) the Prospectus, as of its date and, as amended or supplemented, at the Closing Date, included or includes 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 (except as to financial statements, schedules and notes thereto or other financial, numerical, accounting, statistical or quantitative information (or the assumptions with respect thereto) included or incorporated by reference therein or excluded therefrom and that part of the Registration Statement that constitutes the Statement of Eligibility on Form T-1 upon which such assurance statement need not pass).

(d) At the Closing Date, the Representative shall receive from R. ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇, General Counsel of the Company, a favorable opinion in form and substance satisfactory to counsel for the Underwriters, to the effect that:

(i) The Company has been incorporated, is validly existing as a corporation and its status is active under the laws of the State of Florida;

(ii) The Company is duly authorized by its Charter to conduct the business that it is now conducting as set forth in the Pricing Disclosure Package and the Prospectus;

(iii) The Company is an electrical utility engaged in the business of generating, transmitting, distributing and selling electric power to the general public in the State of Florida;

(iv) The Company has valid and subsisting franchises, licenses and permits adequate for the conduct of its business, except where the failure to hold such franchises, licenses and permits would not have a material adverse effect on the business, properties, results of operations or financial condition of the Company;

(v) The Company has good and marketable title, with minor exceptions, restrictions and reservations in conveyances, and defects that are of the nature ordinarily found in properties of similar character and magnitude and that, in his opinion, will not in any substantial way impair the security afforded by the Mortgage, to all the properties described in the granting clauses of the Mortgage and upon which the Mortgage purports to create a lien. The description in the Mortgage of the above-mentioned properties is legally sufficient to constitute the Mortgage a lien upon said properties, including, without limitation, properties hereafter acquired by the Company (other than those expressly excepted and reserved therefrom). Said properties constitute substantially all the permanent physical properties and franchises (other than those expressly excepted and reserved therefrom) of the Company and are held by the Company free and clear of all liens and encumbrances except the lien of the Mortgage and excepted encumbrances, as defined in the Mortgage. The properties of the Company are subject to liens for current taxes, which it is the practice of the Company to pay regularly as and when due. The Company has easements for rights-of-way adequate for the operations and maintenance of its transmission and distribution lines that are not constructed upon public highways. The Company has followed the practice generally of acquiring (i) certain rights-of-way and easements and certain small parcels of fee property appurtenant thereto and for use in conjunction therewith and (ii) certain other properties of small or inconsequential value, without an examination of title and, as to the title to lands affected by said rights-of-way and easements, of not examining the title of the lessor or grantor whenever the lands affected by such rights-of-way and easements are not of such substantial value as in the opinion of the Company to justify the expense attendant upon examination of titles in connection therewith. In the opinion of said counsel, such practice of the Company is consistent with sound economic practice and with the method followed by other companies engaged in the same business and is reasonably adequate to assure the Company of good and marketable title to all such property acquired by it. It is the opinion of said counsel that any such conditions or defects as may be covered by the above recited exceptions are not substantial and would not materially interfere with the Company’s use of such properties or with its business operations. The Company has the right of eminent domain in the State of Florida under which it may, if necessary, perfect or obtain title to privately owned land or acquire easements or rights-of-way required for use or used by the Company in its public utility operations;

(vi) The Mortgage has been duly and validly authorized by all necessary corporate action, has been duly and validly executed and delivered by the Company, and is a valid and binding mortgage of the Company enforceable in accordance with its terms, except as limited by bankruptcy, insolvency or other laws affecting mortgagees’ and other creditors’ rights and general equitable principles and any implied covenant of good faith and fair dealing; provided, however, that certain remedies, waivers and other provisions of the Mortgage may

not be enforceable, but such unenforceability will not render the Mortgage invalid as a whole or affect the judicial enforcement of (A) the obligation of the Company to repay the principal, together with the interest thereon as provided in the Securities or (B) the right of the Trustee to exercise its right to foreclose under the Mortgage;

(vii) The Mortgage has been recorded and filed in such manner and in such places as may be required by law in order fully to preserve and protect, in all material respects, the security of the bondholders and all rights of the Trustee thereunder; and the Fiftieth Supplemental Indenture relating to the Securities is in proper form for filing for record, both as a real estate mortgage and as a security interest, in all counties in the State of Florida in which any of the property (except as any therein or in the Mortgage are expressly excepted) described therein or in the Mortgage as subject to the lien of the Mortgage is located and, as a security interest, with the Surface Transportation Board and, upon such recording, the Fiftieth Supplemental Indenture will constitute adequate record notice to perfect the lien of the Mortgage, and preserve and protect, in all material respects, the security of the bondholders and all rights of the Trustee, as to all mortgaged and pledged property acquired by the Company subsequent to the recording of the Forty-Ninth Supplemental Indenture and prior to the recording of the Fiftieth Supplemental Indenture;

(viii) The Mortgage constitutes a valid, direct and first mortgage lien of record upon all franchises and properties now-owned by the Company (other than those expressly excepted therefrom and other than those franchises and properties which are not, individually or in the aggregate, material to the Company or the security afforded by the Mortgage) situated in the State of Florida, as described or referred to in the granting clauses of the Mortgage, subject to the exceptions as to bankruptcy, insolvency and other laws stated in subdivision (i) of subparagraph (c) above;

(ix) The issuance and sale of the Securities have been duly authorized by all necessary corporate action on the part of the Company;

(x) Assuming authentication of the Securities by the Trustee in accordance with the Mortgage and delivery of the Securities to and payment for the Securities by the Underwriters, as provided in this Agreement, the Securities have been duly and validly authorized, executed and delivered and are legal, valid and binding obligations of the Company enforceable in accordance with their terms, except as limited by bankruptcy, insolvency or other laws affecting mortgagees’ and other creditors’ rights and general equitable principles and any implied covenant of good faith and fair dealings, and are entitled to the benefits of the security afforded by the Mortgage, and are secured equally and ratably with all other bonds outstanding under the Mortgage except insofar as any sinking or other fund may afford additional security for the bonds of any particular series;

(xi) An order has been entered by the Florida Public Service Commission authorizing the issuance and sale of the Securities, and, to the best of the knowledge of said counsel, said order is still in force and effect; and no further filing with, approval, authorization, consent or other order of any public board or body (except such as have been obtained under the Securities Act and as may be required under the state securities or Blue Sky laws of any jurisdiction) is legally required for the consummation of the transactions contemplated in this Agreement;

(xii) This Agreement has been duly and validly authorized, executed and delivered by the Company;

(xiii) Except as described in or contemplated by the Pricing Disclosure Package and the Prospectus, there are no pending actions, suits or proceedings (regulatory or otherwise) against the Company or any properties that are likely, in the aggregate, to result in any material adverse change in the business, properties, results of operations or financial condition of the Company or that are likely, in the aggregate, to materially and adversely affect the Mortgage, the Securities or the consummation of this Agreement, or the transactions contemplated herein or therein;

(xiv) The consummation of the transactions herein contemplated and the fulfillment of the terms hereof will not (i) result in a breach of any of the terms or provisions of, or constitute a default under, the Charter or the Company’s by-laws or (ii) result in a breach of any terms or provisions of, or constitute a default under, any applicable law or any indenture, mortgage, deed of trust or other material agreement or instrument to which the Company is now a party or any judgment, order, writ or decree of any government or governmental authority or agency or court having jurisdiction over the Company or any of its assets, properties or operations that, in the case of any such breach or default, would have a material adverse effect on business, properties, results of operations or financial condition of the Company; and

(xv) Nothing has come to the attention of said counsel that would lead them to believe that the Registration Statement, at each time and date it was declared, or is deemed to have become, effective by the Commission, 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; and nothing has come to the attention of said counsel that would lead them to believe that (x) the Pricing Disclosure Package, as of the Applicable Time, included an untrue statement of a material fact or omitted 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 or (y) the Prospectus, as of its date and, as amended or supplemented, at the Closing Date, included or includes 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 (except as to financial statements,

schedules and notes thereto or other financial, numerical, accounting, statistical or quantitative information (or the assumptions with respect thereto) included or incorporated by reference therein or excluded therefrom and that part of the Registration Statement that constitutes the Statement of Eligibility on Form T-1 upon which such assurance statement need not pass).

(e) The Representative shall have received on the date hereof and shall receive on the Closing Date from Deloitte & Touche LLP, a letter addressed to the Representative, on behalf of the Underwriters, containing statements and information of the type ordinarily included in accountants’ SAS 72 “comfort letters” to underwriters with respect to the audit reports, financial statements and certain financial information contained in or incorporated by reference into the Pricing Prospectus and the Prospectus.

(f) At the Closing Date, the Representative shall receive a favorable opinion from ▇▇▇▇▇ & ▇▇▇▇▇▇▇ LLP, counsel to the Underwriters, as to such matters as the Representative may reasonably request and in form customary for comparable transactions.

(g) At the Closing Date, the Representative shall receive a certificate of the Chairman, President, Treasurer or a Vice President of the Company, dated the Closing Date, to the effect that the representations and warranties of the Company in this Agreement are true and correct as of the Closing Date.

(h) Any Permitted Free Writing Prospectus, and any other material required pursuant to Rule 433(d) under the Securities Act, shall have been filed by the Company with the Commission within the applicable time periods prescribed by Rule 433.

(i) All legal proceedings taken in connection with the sale and delivery of the Securities shall have been satisfactory in form and substance to counsel for the Underwriters, and the Company, as of the Closing Date, shall be in compliance with any governing order of the Florida Public Service Commission, except where the failure to comply with such order would not be material to the offering or validity of the Securities.

In case any of the conditions specified above in this paragraph 9 shall not have been fulfilled or waived by 2:00 p.m., New York City time, on the Closing Date, this Agreement may be terminated by the Representative by delivering written notice thereof to the Company. Any such termination shall be without liability of any party to any other party except as otherwise provided in paragraphs 7 and 8 hereof.

10. Conditions of the Company’s Obligations. The obligations of the Company to deliver the Securities shall be subject to the following conditions:

(a) No stop order suspending the effectiveness of the Registration Statement shall be in effect on the Closing Date, no proceedings for that purpose shall be pending before or threatened by the Commission on the Closing Date and no notice from the Commission pursuant to Rule 401(g)(2) of the Securities Act shall have been received by the Company.

(b) Prior to 12:00 Noon, New York City time, on the day following the date of this Agreement, or such later date as shall have been consented to by the Company, there shall have been issued and on the Closing Date there shall be in full force and effect an order of the Florida Public Service Commission authorizing the issuance and sale by the Company of the Securities, which shall not contain any provision unacceptable to the Company by reason of its being materially adverse to the Company (it being understood that the order in effect as of the date of this Agreement does not contain any such unacceptable provision).

In case any of the conditions specified in this paragraph 10 shall not have been fulfilled at the Closing Date, this Agreement may be terminated by the Company by delivering written notice thereof to the Representative. Any such termination shall be without liability of any party to any other party except as otherwise provided in paragraphs 7 and 8 hereof.

11. Indemnification.

(a) The Company agrees to indemnify and hold harmless each Underwriter, each officer and director of each Underwriter and each person who controls any Underwriter within the meaning of Section 15 of the Securities Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject and to reimburse each such Underwriter, each such officer and director, and each such controlling person for any legal or other expenses (including to the extent hereinafter provided, reasonable counsel fees) incurred by them, when and as incurred, in connection with investigating any such losses, claims, damages or liabilities or in connection with defending any actions, insofar as such losses, claims, damages, liabilities, expenses or actions arise out of or are based upon any untrue statement, or alleged untrue statement, of a material fact contained in the Registration Statement, the Pricing Disclosure Package or the Prospectus, or in the Registration Statement or Prospectus as amended or supplemented (if any amendments or supplements thereto shall have been furnished), or in any issuer free writing prospectus (as defined in Rule 433 of the Securities Act), or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; provided, however, that the indemnity agreement contained in this paragraph 11 shall not apply to any such losses, claims, damages, liabilities, expenses or actions arising out of or based upon any such untrue statement or alleged untrue statement, or any such omission or alleged omission, if such statement or omission was made in reliance upon and in conformity with the information furnished herein or in writing to the Company by any Underwriter through the Representative expressly for use in the Registration Statement,

the Pricing Disclosure Package or the Prospectus, or any amendment or supplement to any thereof, or any free writing prospectus used by the Company, or arising out of, or based upon, statements in or omissions from that part of the Registration Statement that shall constitute the Statement of Eligibility under the 1939 Act (Form T-1) of the Trustee. The indemnity agreement of the Company contained in this paragraph 11 and the representations and warranties of the Company contained in paragraph 3 hereof shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any Underwriter, and any such officer or director or any such controlling person and shall survive the delivery of the Securities. The Underwriters agree to notify promptly the Company, and each other Underwriter, of the commencement of any litigation or proceedings against them or any of them, or any such officer or director, or any such controlling person, in connection with the sale of the Securities.

(b) Each Underwriter severally, and not jointly, agrees to indemnify and hold harmless the Company, its officers who signed the Registration Statement and its directors, and each person who controls the Company within the meaning of Section 15 of the Securities Act, against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject and to reimburse each of them for any legal or other expenses (including, to the extent hereinafter provided, reasonable counsel fees) incurred by them, when and as incurred, in connection with investigating any such losses, claims, damages, or liabilities, or in connection with defending any actions, insofar as such losses, claims, damages, liabilities, expenses or actions arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Pricing Disclosure Package, the Prospectus as amended or supplemented (if any amendments or supplements thereto shall have been furnished), or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, if such statement or omission was made in reliance upon and in conformity with information furnished herein or in writing to the Company by such Underwriter or through the Representative on behalf of such Underwriter expressly for use in the Registration Statement or the Pricing Disclosure Package or any amendment or supplement to any thereof. The indemnity agreement of all the respective Underwriters contained in this paragraph 11 shall remain operative and in full force and effect regardless of any investigation made by or on behalf of the Company or any other Underwriter, or any such officer or director or any such controlling person, and shall survive the delivery of the Securities. The Company agrees promptly to notify the Representative of the commencement of any litigation or proceedings against the Company or any of its officers or directors, or any such controlling person, in connection with the sale of the Securities.

(c) The Company and each of the Underwriters agree that, upon the receipt of notice of the commencement of any action against it, its officers or directors, or any person controlling it as aforesaid, in respect of which indemnity may be sought on account of any indemnity agreement contained herein, it will promptly give written notice of the commencement thereof to the party or parties against whom indemnity shall be sought hereunder. The Company and each of the Underwriters agree that the notification required by the preceding sentence shall be a material term of this

Agreement. The omission so to notify such indemnifying party or parties of any such action shall relieve such indemnifying party or parties from any liability that it or they may have to the indemnified party on account of any indemnity agreement contained herein if such indemnifying party was materially prejudiced by such omission, but shall not relieve such indemnifying party or parties from any liability that it or they may have to the indemnified party otherwise than on account of such indemnity agreement. In case such notice of any such action shall be so given, such indemnifying party shall be entitled to participate at its own expense in the defense or, if it so elects, to assume (in conjunction with any other indemnifying parties) the defense of such action, in which event such defense shall be conducted by counsel chosen by such indemnifying party (or parties) and satisfactory to the indemnified party or parties who shall be defendant or defendants in such action, and such defendant or defendants shall bear the fees and expenses of any additional counsel retained by them; but if the indemnifying party shall elect not to assume the defense of such action, such indemnifying parties will reimburse such indemnified party or parties for the reasonable fees and expenses of any counsel retained by them, as such expenses are incurred; provided, however, if the defendants (including any impleaded parties) in any such action include both the indemnified party and the indemnifying party, and counsel for the indemnified party shall have concluded, in its reasonable judgment, that there may be a conflict of interest involved in the representation by such counsel of both the indemnifying party and the indemnified party, the indemnified party or parties shall have the right to select separate counsel, satisfactory to the indemnifying party, to participate in the defense of such action on behalf of such indemnified party or parties (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (in addition to one local counsel) representing the indemnified parties who are parties to such action). Each of the Company and the several Underwriters agrees that without the other party’s prior written consent, which consent shall not be unreasonably withheld, it will not settle, compromise or consent to the entry of any judgment in any claim in respect of which indemnification may be sought under the indemnification provisions of this Agreement, unless such settlement, compromise or consent includes an unconditional release of such other party from all liability arising out of such claim.

(d) If the indemnification provided for in subparagraphs (a) or (b) above 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 Securities 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 that 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 Securities pursuant to this Agreement shall be deemed to be in the

same respective proportions as the total net proceeds from the offering of the Securities 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 initial public offering price of the Securities 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 the 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 the Underwriters 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 subparagraph (d) 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 that does not take account of the equitable considerations referred to above in this subparagraph (d). The rights of contribution contained in this Section 11 shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any Underwriter or the Company and shall survive delivery of the Securities. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this subparagraph (d), each officer and director of each Underwriter and each person, if any, who controls an Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange 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 Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Company. The Underwriters’ respective obligations to contribute pursuant to this subparagraph (d) are several in proportion to the principal amount of Securities set forth opposite their respective names in Schedule I hereto and not joint.

(e) For purposes of this paragraph 11, it is understood and agreed that the only information provided by the Underwriters expressly for use in the Registration Statement and the Pricing Disclosure Package were the following parts of the Preliminary Prospectus section titled “Underwriting”: the second, third and fourth sentences of the second paragraph, the third sentence of the third paragraph, all of the fourth paragraph, the first sentence of the seventh paragraph and all of the eighth paragraph.

12. Termination Date of this Agreement. This Agreement may be terminated by the Representative at any time prior to the Closing Date by delivering written notice thereof to the Company, if on or after the date of this Agreement but prior to such time (a) there shall have occurred any general suspension of trading in securities on The New York Stock Exchange, or there shall have been established by The New York Stock Exchange or by the Commission or by any federal or state agency or by the decision of any court, any limitation on prices for such trading or any restrictions on the distribution of securities or (b) there shall have occurred any new outbreak of hostilities including, but not limited to, significant escalation of hostilities that existed on or prior to the date of this Agreement, or any national or international calamity or

crisis, or any material adverse change in the financial markets of the United States, the effect of which outbreak, escalation, calamity or crisis, or material adverse change in the financial markets of the United States shall be such as to make it impracticable, in the reasonable judgment of the Representative, for the Underwriters to enforce contracts for the sale of the Securities, or (c) the Company shall have sustained a substantial loss by fire, flood, accident or other calamity that renders it impracticable, in the reasonable judgment of the Representative, to consummate the sale of the Securities and the delivery of the Securities by the several Underwriters at the initial public offering price, or (d) there shall have been any downgrading or any notice of any intended or potential downgrading in the rating accorded the Company’s securities by any “nationally recognized statistical rating organization” as that term is defined by the Commission for the purposes of Rule 436(g)(2) under the Securities Act, or any such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of the Securities, or any of the Company’s other outstanding debt, the effect of which in the reasonable judgment of the Representative, makes it impracticable or inadvisable to consummate the sale of the Securities and the delivery of the Securities by the several Underwriters at the initial public offering price or (e) there shall have been declared, by either federal or New York authorities, a general banking moratorium. This Agreement may also be terminated at any time prior to the Closing Date if in the reasonable judgment of the Representative the subject matter of any amendment or supplement to the Registration Statement, the Preliminary Prospectus or Prospectus (other than an amendment or supplement relating solely to the activity of any Underwriter or Underwriters) filed after the execution of this Agreement shall have materially impaired the marketability of the Securities. Any termination hereof pursuant to this paragraph 12 shall be without liability of any party to any other party except as otherwise provided in paragraphs 7 and 8 hereof.

13. Miscellaneous. The validity and interpretation of this Agreement shall be governed by the laws of the State of New York. Unless otherwise specified, time of day refers to New York City time. This Agreement shall inure to the benefit of, and be binding upon, the Company, the several Underwriters, and with respect to the provisions of paragraph 11 hereof, the officers and directors and each controlling person referred to in paragraph 11 hereof, and their respective successors. Nothing in this Agreement is intended or shall be construed to give to any other person, firm or corporation any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. The term “successors” as used in this Agreement shall not include any purchaser, as such purchaser, of any of the Securities from any of the several Underwriters.

14. Nature of Relationship. The Company acknowledges and agrees that (i) in connection with all aspects of each transaction contemplated by this Agreement, the Company and the Underwriters have an arms-length business relationship that creates no fiduciary duty on the part of any party and each expressly disclaims any fiduciary relationship, (ii) the Underwriters and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company, (iii) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Company has consulted its own legal, accounting, regulatory and tax advisors to the extent it deemed appropriate, and (iv) any review by the Underwriters of the Company, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriters and shall not be on behalf of the Company.

15. Patriot Act. In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the underwriters are required to obtain, verify and record information that identifies their respective clients, including the Company, which information may include the name and address of their respective clients, as well as other information that will allow the underwriters to properly identify their respective clients.
