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.

12

(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, Mitchell & Jernigan, 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

13

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. Alexander Glenn, 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;

14

(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

15

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;

16

(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,

17

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 Dewey & LeBoeuf 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.

18

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,

19

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

20

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

21

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

22

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.

23

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.
