▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇

Ladies and Gentlemen:

Vectren Utility Holdings, Inc., an Indiana corporation (the “Company”), proposes to issue and sell an aggregate principal amount of senior debt securities not to exceed $150,000,000 (the “Debt Securities”), from time to time, in or pursuant to one or more offerings on terms to be determined at the time of sale. The Debt Securities will be issued in one or more series as senior indebtedness under an indenture, dated as of October 19, 2001 (as modified, supplemented or amended from time to time, the “Indenture”), among the Company, as issuer, the Initial Guarantors (as defined below), as guarantors, and U.S. Bank Trust National Association, as trustee (the “Trustee”), and, subject to the terms of the Indenture, will be fully and unconditionally guaranteed as to payment of principal, premium (if any) and interest (the “Guarantees,” and together with the Debt Securities, the “Securities”) by Indiana Gas Company, Inc., an Indiana and Ohio corporation, Southern Indiana Gas and Electric Company, an Indiana corporation, and Vectren Energy Delivery of Ohio, Inc., an Ohio corporation (collectively, the “Initial Guarantors” and, together with each other subsidiary of the Company that pursuant to the terms of the Indenture guarantees the Company’s obligations under the Debt Securities, the “Guarantors”).

Each series of Debt Securities may vary, as applicable, as to title, aggregate principal amount, rank, interest rate or formula and timing of payments thereof, stated maturity date, redemption and/or repayment provisions, sinking fund requirements and any other variable terms established by or pursuant to the Indenture.

Whenever the Company determines to make an offering of Securities through LaSalle Financial Services, Inc. (the “Representative”), or through an underwriting syndicate managed by the Representative, the Company and, if applicable, the Guarantors will enter into an agreement (each, a “Terms Agreement”) providing for the sale of such Securities to, and the purchase and offering thereof by, Representative and such other underwriters, if any, selected by the Representative (the “Underwriters”, which term shall include the Representative, as well as any Underwriter substituted pursuant to Section 10 hereof). The Terms Agreement relating to the offering of Securities shall specify the aggregate principal amount of Debt Securities to be

initially issued (the “Initial Underwritten Securities”), the name of each Underwriter participating in such offering (subject to substitution as provided in Section 10 hereof) and the name of any Underwriter other than the Representative acting as co-manager in connection with such offering, the aggregate principal amount of Initial Underwritten Securities which each such Underwriter severally agrees to purchase, whether such offering is on a fixed or variable price basis and, if on a fixed price basis, the initial offering price, the price at which the Initial Underwritten Securities are to be purchased by the Underwriters, the form, time, date and place of delivery and payment of the Initial Underwritten Securities and any other material variable terms of the Initial Underwritten Securities. In addition, if applicable, such Terms Agreement shall specify whether the Company has agreed to grant to the Underwriters an option to purchase additional Securities to cover over-allotments, if any, and the aggregate principal amount of Debt Securities subject to such option (the “Option Underwritten Securities”). As used herein, the term “Underwritten Securities” shall include the Initial Underwritten Securities and all or any portion of any Option Underwritten Securities. The Terms Agreement, which shall be substantially in the form of Exhibit A hereto, may take the form of an exchange of any standard form of written telecommunication between the Company and the Representative acting for itself and, if applicable, for any other Underwriters. Each offering of Underwritten Securities through the Representative will be governed by this Underwriting Agreement, as supplemented by the applicable Terms Agreement.

The Company and the Initial Guarantors have filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (No. 333-128286) for the registration of the Securities under the Securities Act of 1933, as amended (the “1933 Act”), and the offering thereof from time to time in accordance with Rule 415 of the rules and regulations of the Commission under the 1933 Act (the “1933 Act Regulations”). Such registration statement has been declared effective by the Commission and the Indenture has been duly qualified under the Trust Indenture Act of 1939, as amended (the “1939 Act”), and the Company and the Initial Guarantors have or will have filed such post-effective amendments thereto as may be required prior to the execution of the applicable Terms Agreement and each such post-effective amendment has been declared effective by the Commission. Such registration statement (as so amended, if applicable), including the information, if any, deemed to be a part thereof pursuant to Rule 430A(b) of the 1933 Act Regulations (the “Rule 430A Information”) or Rule 434(d) of the 1933 Act Regulations (the “Rule 434 Information”), is referred to herein as the “Registration Statement”; and the final prospectus and the final prospectus supplement relating to the offering of the Underwritten Securities, in the respective forms first furnished to the Underwriters by the Company for use in connection with the offering of the Underwritten Securities, are collectively referred to herein as the “Prospectus”; provided, however, that all references to the “Registration Statement” and the “Prospectus” shall also be deemed to include the information in all documents incorporated therein by reference pursuant to the Securities Exchange Act of 1934, as amended (the “1934 Act”), prior to the execution of the applicable Terms Agreement; provided, further, that if the Company and the Guarantors file a registration statement with the Commission pursuant to Rule 462(b) of the 1933 Act Regulations (the “Rule 462(b) Registration Statement”), then, after such filing, all references to “Registration Statement” shall also be deemed to include the Rule 462(b) Registration Statement; and provided, further, that if the Company elects to rely upon Rule 434 of the 1933 Act Regulations, then all references to “Prospectus” shall also be deemed to include the final or preliminary prospectus and the applicable term sheet or abbreviated term sheet (the “Term Sheet”), as the case may be, in the

respective forms first furnished to the Underwriters by the Company in reliance upon Rule 434 of the 1933 Act Regulations, and all references to the date of the Prospectus shall mean the date of the Term Sheet. A “preliminary prospectus” shall be deemed to refer to (i) any prospectus used before the Registration Statement became effective and (ii) any prospectus that omitted, as applicable, the Rule 430A Information, the Rule 434 Information or other information to be included upon pricing in a form of prospectus filed with the Commission pursuant to Rule 424(b) of the 1933 Act Regulations and was used after such effectiveness and prior to the initial delivery of the Prospectus to the Underwriters by the Company. For purposes of this Underwriting Agreement, all references to the Registration Statement, Prospectus, Term Sheet or preliminary prospectus or to any amendment or supplement to any of the foregoing shall be deemed to include any copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system (“▇▇▇▇▇”).

All references in this Underwriting Agreement to financial statements and schedules and other information which is “contained,” “included,” “disclosed” or “stated” (or other references of like import) in the Registration Statement, Prospectus or preliminary prospectus shall be deemed to include all such financial statements and notes and schedules thereto and other information which is incorporated by reference in the Registration Statement, Prospectus or preliminary prospectus, as the case may be, prior to the execution of the applicable Terms Agreement; and all references in this Underwriting Agreement to amendments or supplements to the Registration Statement, Prospectus or preliminary prospectus shall be deemed to include the information which is incorporated by reference in the Registration Statement, Prospectus or preliminary prospectus, as the case may be, at or after the execution of the applicable Terms Agreement.

SECTION 1. Representations and Warranties.

(a) Representations and Warranties by the Company and the Guarantors. Each of the Company and the Guarantors, jointly and severally, represents and warrants to the Representative, as of the date hereof, and to each Underwriter named in the applicable Terms Agreement, as of the date thereof, as of the Closing Time (as defined below) and, if applicable, as of each Date of Delivery (as defined below) (in each case, a “Representation Date”), as follows:

(1) Compliance with Registration Requirements. Each of the Company and the Guarantors meets the requirements for use of Form S-3 under the 1933 Act. The Registration Statement (including any Rule 462(b) Registration Statement) has become effective under the 1933 Act and no stop order suspending the effectiveness of the Registration Statement (or such Rule 462(b) Registration Statement) has been issued under the 1933 Act and no proceedings for that purpose have been instituted or are pending or, to the knowledge of the Company and the Guarantors, are contemplated by the Commission, and any request on the part of the Commission for additional information has been complied with. In addition, the Indenture has been duly qualified under the 1939 Act.

At the respective times the Registration Statement (including any Rule 462(b) Registration Statement) and any post-effective amendments thereto (including the filing

of the Company’s most recent Annual Report on Form 10-K with the Commission (the “Annual Report on Form 10-K”)) became effective and at each Representation Date, the Registration Statement (including any Rule 462(b) Registration Statement) and any amendments thereto complied and will comply in all material respects with the requirements of the 1933 Act and the 1933 Act Regulations and the 1939 Act and the rules and regulations of the Commission under the 1939 Act (the “1939 Act Regulations”) and did not and will 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. At the date of the Prospectus, at the Closing Time and at each Date of Delivery, if any, neither the Prospectus nor any amendment or supplement thereto included or will include an untrue statement of a material fact or omitted or will 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. If the Company elects to rely upon Rule 434 of the 1933 Act Regulations, the Company will comply with the requirements of Rule 434. Notwithstanding the foregoing, the representations and warranties in this subsection shall not apply to the Statement of Eligibility of the Trustee on Form T-1 or statements in or omissions from the Registration Statement or the Prospectus made in reliance upon and in conformity with information furnished to the Company or a Guarantor in writing by any Underwriter through the Representative expressly for use in the Registration Statement or the Prospectus.

Each preliminary prospectus and prospectus filed as part of the Registration Statement as originally filed or as part of any amendment thereto, or filed pursuant to Rule 424 under the 1933 Act, complied when so filed in all material respects with the 1933 Act Regulations and each preliminary prospectus and the Prospectus delivered to the Underwriters for use in connection with the offering of Underwritten Securities will, at the time of such delivery, be identical to any electronically transmitted copies thereof filed with the Commission pursuant to ▇▇▇▇▇, except to the extent permitted by Regulation S-T.

(2) Incorporated Documents. The documents incorporated or deemed to be incorporated by reference in the Registration Statement and the Prospectus, at the time they were or hereafter are filed with the Commission, complied and will comply in all material respects with the requirements of the 1934 Act and the rules and regulations of the Commission thereunder (the “1934 Act Regulations”) and, when read together with the other information in the Prospectus, at the date of the Prospectus, at the Closing Time and at each Date of Delivery, if any, did not and will not include 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.

(3) Independent Accountants. The accountants that audited the Company’s financial statements and supporting schedules thereto included in the Registration Statement and the Prospectus, as specified therein, are an independent registered public accounting firm within the meaning of the 1933 Act and the 1933 Act Regulations.

(4) Financial Statements. The consolidated financial statements included in the Registration Statement and the Prospectus, together with the related schedules and

notes, present fairly the financial position of the Company and its consolidated subsidiaries at the dates indicated and the statement of operations, stockholders’ equity and cash flows of the Company and its consolidated subsidiaries for the periods specified. Such financial statements have been prepared in conformity with generally accepted accounting principles (“GAAP”) applied on a consistent basis throughout the periods involved. The supporting schedules, if any, included in the Registration Statement and the Prospectus present fairly in accordance with GAAP the information required to be stated therein. The selected financial data and the summary financial information, if any, included in the Prospectus present fairly the information shown therein and have been compiled on a basis consistent with that of the audited financial statements included in the Registration Statement and the Prospectus. The Company is not required to include any pro forma financial statements in the Registration Statement or the Prospectus under the 1933 Act or the 1933 Act Regulations or any document required to be filed with the Commission under the 1934 Act or the 1934 Act Regulations. The financial statement presentation of the Company and the Guarantors in the Prospectus satisfies the conditions of Rule 3-10(f) of Regulation S-X promulgated under the 1933 Act.

(5) No Material Adverse Change in Business. Since the respective dates as of which information is given in the Registration Statement and the Prospectus, except as otherwise stated therein, (A) there has been no material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business (a “Material Adverse Effect”), (B) there have been no transactions entered into by the Company or any of its subsidiaries, other than those arising in the ordinary course of business, which are material with respect to the Company and its subsidiaries considered as one enterprise and (C) there has been no dividend or distribution of any kind declared, paid or made by the Company on any class of its capital stock.

The Company is duly qualified as a foreign corporation to transact business and is in good standing in each other jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure to so qualify or be in good standing could not reasonably be expected to result in a Material Adverse Effect.

(7) Good Standing of Guarantors. Each Guarantor has been duly organized, is validly existing and is in good standing under the laws of the jurisdiction of its incorporation or organization (to the extent applicable), has power and authority (corporate and other) to own, lease and operate its properties, to conduct its business as described in the Prospectus and to enter into and perform its obligations under, or as contemplated under, this Underwriting Agreement, the applicable Terms Agreement and

its Guarantee and is duly qualified as a foreign corporation or limited liability company, as applicable, to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure to so qualify or be in good standing could not reasonably be expected to result in a Material Adverse Effect. All of the issued and outstanding capital stock or other equity interests of each Guarantor have been duly authorized and are validly issued, are fully paid and non-assessable and are owned by the Company, directly or through subsidiaries, free and clear of any security interest, mortgage, pledge, lien, encumbrance, claim or equity. None of the outstanding shares of capital stock or other equity interests of any Guarantor were issued in violation of preemptive or other similar rights of any securityholder of such Guarantor. The only subsidiaries of the Company are (a) the Guarantors and (b) certain other subsidiaries which, individually or in the aggregate, are “minor” within the meaning of Rule 3-10 of Regulation S-X promulgated under the ▇▇▇▇ ▇▇▇.

All of the issued and outstanding shares of capital stock of the Company have been duly authorized and validly issued by the Company and are fully paid and non-assessable, and none of such shares of capital stock were issued in violation of preemptive or other similar rights of any securityholder of the Company.

Such Underwritten Securities will be in

the form contemplated by, and each registered holder thereof is entitled to the benefits of, the Indenture and the Guarantees.

(11) Authorization of Guarantees. The Guarantees have been, or as of the date of the applicable Terms Agreement will have been, duly authorized by the respective Guarantors; the Guarantees, when the Underwritten Securities are issued and authenticated in the manner provided for in the Indenture and delivered against payment of the consideration therefor specified in such Terms Agreement, will constitute valid and binding obligations of the respective Guarantors, enforceable against the related Guarantor in accordance with their terms, except as the enforcement thereof may be limited by bankruptcy, insolvency (including, without limitation, all laws relating to fraudulent transfers), reorganization, moratorium or other similar laws affecting the enforcement of creditors’ rights generally or by general equitable principles (regardless of whether enforcement is considered in a proceeding in equity or at law), and except further as enforcement thereof may be limited by requirements that a claim with respect to any Guarantee payable in a foreign currency (or a foreign currency judgment in respect of such claim) be converted into U.S. dollars at a rate of exchange prevailing on a date determined pursuant to applicable law or by governmental authority to limit, delay or prohibit the making of payments outside the United States.

(14) Description of the Indenture. The Indenture, as of the Representation Date, will conform in all material respects to the statements relating thereto contained in the Prospectus and will be in substantially the form filed or incorporated by reference, as the case may be, as an exhibit to the Registration Statement.

(15) Absence of Defaults and Conflicts. Neither the Company nor any of its subsidiaries is in violation of its charter or by-laws (or other organizational documents) or in default in the performance or observance of any obligation, agreement, covenant or condition contained in any contract, indenture, mortgage, deed of trust, loan or credit agreement, note, lease or other agreement or instrument to which the Company or any of its subsidiaries is a party or by which it or any of them may be bound, or to which any of the assets, properties or operations of the Company or any of its subsidiaries is subject (collectively, “Agreements and Instruments”), except for such violations or defaults that could not reasonably be expected to result in a Material Adverse Effect. The execution, delivery and performance of this Underwriting Agreement, the applicable Terms Agreement and the Indenture and any other agreement or instrument entered into or issued or to be entered into or issued by the Company and each Guarantor in connection with the transactions contemplated hereby or thereby or in the Registration Statement and the Prospectus and the consummation of the transactions contemplated herein and in the Registration Statement and the Prospectus (including the issuance and sale of the Underwritten Securities and the use of the proceeds from the sale of the Underwritten Securities as described under the caption “Use of Proceeds” in the Prospectus relating to such Underwritten Securities) and compliance by the Company and each Guarantor with their respective obligations hereunder and thereunder have been duly authorized by all necessary corporate action and do not and will not, whether with or without the giving of notice or passage of time or both, conflict with or constitute a breach of, or default or Repayment Event (as defined below) under, or result in the creation or imposition of any lien, charge or encumbrance upon any assets, properties or operations of the Company or any of its subsidiaries pursuant to, any Agreements and Instruments, nor will such action result in any violation of the provisions of the charter or by-laws (or other organizational documents) of the Company or any of its subsidiaries or any applicable law, statute, rule, regulation, judgment, order, writ or decree of any government, government instrumentality or court, domestic or foreign, having jurisdiction over the Company or any of its subsidiaries or any of their respective assets, properties or operations. As used herein, a “Repayment Event” means any event or condition which gives the holder of any note, debenture or other evidence of indebtedness (or any person acting on such holder’s behalf) the right to require the repurchase, redemption or repayment of all or a portion of such indebtedness by the Company or any of its subsidiaries.

(16) Absence of Labor Dispute. No labor dispute with the employees of the Company or any of its subsidiaries exists or, to the knowledge of the Company, is imminent, and the Company is not aware of any existing or imminent labor disturbance by the employees of any of its or any of its subsidiaries’ principal suppliers, manufacturers, customers or contractors, which, in either case, could reasonably be expected to result in a Material Adverse Effect.

(17) Absence of Proceedings. Except as otherwise disclosed in the Registration Statement or the Prospectus, there is no action, suit, proceeding, inquiry or investigation before or brought by any court or governmental agency or body, domestic or foreign, now pending, or to the knowledge of the Company threatened, against or affecting the Company or any of its subsidiaries which (A) is required to be disclosed in the Registration Statement and the Prospectus (other than as stated therein), (B) could

reasonably be expected to result in a Material Adverse Effect, or (C) could reasonably be expected to materially and adversely affect the consummation of the transactions contemplated under the Prospectus, this Underwriting Agreement, the applicable Terms Agreement or the Indenture or the performance by the Company and the Guarantors of their respective obligations hereunder and thereunder. The aggregate of all pending legal or governmental proceedings to which the Company or any of its subsidiaries is a party or of which any of their respective assets, properties or operations is the subject which are not described in the Registration Statement and the Prospectus, including ordinary routine litigation incidental to the business, could not reasonably be expected to result in a Material Adverse Effect.

(18) Accuracy of Exhibits. There are no franchises, contracts or other documents which are required to be described in the Registration Statement, the Prospectus or the documents incorporated by reference therein or to be filed as exhibits thereto which have not been so described and filed as required.

(19) Absence of Further Requirements. No filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any court or governmental authority or agency, domestic or foreign, is necessary or required for the due authorization, execution and delivery by the Company or the Guarantors of this Underwriting Agreement, the applicable Terms Agreement, the Indenture, the Underwritten Securities or the Guarantees or for the performance by the Company or the Guarantors of their obligations under this Underwriting Agreement, such Terms Agreement, the Indenture, the Underwritten Securities or the Guarantees, except such as have been already made, obtained or rendered, as applicable or as may be required under state securities or blue sky laws.

(20) Possession of Intellectual Property. The Company and its subsidiaries own or possess, or can acquire on reasonable terms, adequate patents, patent rights, licenses, inventions, copyrights, know-how (including trade secrets and other unpatented and/or unpatentable proprietary or confidential information, systems or procedures), trademarks, service marks, trade names or other intellectual property (collectively, “Intellectual Property”) necessary to carry on the business now operated by them, except where the failure to own, possess or acquire, singly or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect. Neither the Company nor any of its subsidiaries has received any notice or is otherwise aware of any infringement of or conflict with asserted rights of others with respect to any Intellectual Property or of any facts or circumstances which would render any Intellectual Property invalid or inadequate to protect the interest of the Company or any of its subsidiaries therein, and which infringement or conflict (if the subject of any unfavorable decision, ruling or finding) or invalidity or inadequacy, singly or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect.

(21) Possession of Licenses and Permits. Except as otherwise disclosed in the Registration Statement or the Prospectus, (i) the Company and its subsidiaries possess such permits, licenses, approvals, consents and other authorizations (collectively, “Governmental Licenses”) issued by the appropriate regulatory agencies or bodies,

domestic or foreign, necessary to conduct the business now operated by them, except where the non-possession of any such Governmental Licenses could not reasonably be expected to result in a Material Adverse Effect, (ii) the Company and its subsidiaries are in compliance with the terms and conditions of all such Governmental Licenses, except where the failure so to comply could not, singly or in the aggregate, reasonably be expected to result in a Material Adverse Effect, (iii) all of the Governmental Licenses are valid and in full force and effect, except where the invalidity of such Governmental Licenses or the failure of such Governmental Licenses to be in full force and effect could not reasonably be expected to result in a Material Adverse Effect and (iv) neither the Company nor any of its subsidiaries has received any notice of proceedings relating to the revocation or modification of any such Governmental Licenses which, singly or in the aggregate, if the subject of an unfavorable decision, ruling or finding, could reasonably be expected to result in a Material Adverse Effect.

(22) Title to Property. The Company and its subsidiaries have good and marketable title to all material real property owned by the Company and its subsidiaries and good title to all other material properties owned by them, in each case, free and clear of all mortgages, pledges, liens, security interests, claims, restrictions or encumbrances of any kind, except (A) as otherwise stated in the Registration Statement and the Prospectus or (B) those which do not, singly or in the aggregate, materially affect the value of such property and do not interfere with the use made or proposed to be made of such property by the Company or any of its subsidiaries. All of the leases and subleases material to the business of the Company and its subsidiaries considered as one enterprise, and under which the Company or any of its subsidiaries holds properties described in the Prospectus, are in full force and effect, and neither the Company nor any of its subsidiaries has received any notice of any material claim of any sort that has been asserted by anyone adverse to the rights of the Company or any of its subsidiaries under any of the leases or subleases mentioned above, or affecting or questioning the rights of the Company or such subsidiary to the continued possession of the leased or subleased premises under any such lease or sublease.

(23) Investment Company Act. Neither the Company nor any Guarantor is, or upon the issuance and sale of the Underwritten Securities as herein contemplated and the application of the net proceeds therefrom as described in the Prospectus will be, an “investment company” within the meaning of the Investment Company Act of 1940, as amended (the “1940 Act”).

(26) Maintenance of Controls and Procedures. The Company has established and maintains “disclosure controls and procedures” (as such term is defined in Rules 13a-15 and 15d-15 under the ▇▇▇▇ ▇▇▇) that (A) are designed to ensure that material information relating to the Company, including its consolidated subsidiaries, is made known to the Company’s Chief Executive Officer and its Chief Financial Officer by others within those entities, particularly during the periods in which the filings made by the Company with the Commission which it may make under Section 13(a), 13(c), 14 or 15(d) of the 1934 Act are being prepared, (B) have been evaluated for effectiveness as of a date within 90 days prior to the filing of the Company’s most recent annual report filed with the Commission and (C) are effective to perform the functions for which they were established.

Any material weaknesses in internal controls have been identified for the Company’s accountants. Since the date of the most recent evaluation of such disclosure controls and procedures, there have been no significant changes in internal controls or in other factors that could significantly affect internal controls, including any corrective actions with regard to significant deficiencies and material weaknesses.

(27) Other Controls. The Company and its consolidated subsidiaries maintain a system of internal accounting and other controls sufficient to provide reasonable assurances that (A) transactions are executed in accordance with management’s general

(28) No Fiduciary Duty. The Company acknowledges and agrees that the Underwriters are acting solely in the capacity of an arm’s length contractual counterparty to the Company with respect to the offering of the Underwritten Securities contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Company or any other person. Additionally, neither the Representative nor any other Underwriter is advising the Company or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction with respect to the offering of the Underwritten Securities contemplated hereby (including in connection with determining the terms of the offering). The Company shall consult with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and the Underwriters shall have no obligation or liability to the Company with respect thereto. 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.

(b) Officers’ Certificates. Any certificate signed by any officer of the Company, any Guarantor or any of their respective subsidiaries and delivered to any Underwriter or to counsel for the Underwriters in connection with the offering of the Underwritten Securities shall be deemed a representation and warranty by the Company or such Guarantor to each Underwriter as to the matters covered thereby on the date of such certificate.

SECTION 2. Sale and Delivery to Underwriters; Closing.

(a) Underwritten Securities. The several commitments of the Underwriters to purchase the Underwritten Securities pursuant to the applicable Terms Agreement shall be deemed to have been made on the basis of the representations, warranties and agreements herein contained and shall be subject to the terms and conditions herein set forth.

(b) Option Underwritten Securities. Subject to the terms and conditions herein set forth, the Company may grant, if so provided in the applicable Terms Agreement, an option to the Underwriters, severally and not jointly, to purchase up to the aggregate principal amount of the Option Underwritten Securities set forth therein at a price equal to the percentage of the aggregate principal amount of the Initial Underwritten Securities representing the purchase price, plus accrued interest or amortized original issue discount, as the case may be, from the original

issue date of the Initial Underwritten Securities. Such option, if granted, will expire 30 days after the date of such Terms Agreement, and may be exercised in whole or in part from time to time only for the purpose of covering over-allotments which may be made in connection with the offering and distribution of the Initial Underwritten Securities upon notice by the Representative to the Company setting forth the number or aggregate principal amount, as the case may be, of Option Underwritten Securities as to which the several Underwriters are then exercising the option and the time, date and place of payment and delivery for such Option Underwritten Securities. Any such time and date of payment and delivery (each, a “Date of Delivery”) shall be determined by the Representative, but shall not be later than seven full business days after the exercise of said option, nor in any event prior to the Closing Time, unless otherwise agreed upon by the Representative and the Company. If the option is exercised as to all or any portion of the Option Underwritten Securities, each of the Underwriters, severally and not jointly, will purchase that proportion of the total aggregate principal amount of Option Underwritten Securities then being purchased which the number or aggregate principal amount, as the case may be, of Initial Underwritten Securities each such Underwriter has severally agreed to purchase as set forth in such Terms Agreement bears to the total aggregate principal amount of Initial Underwritten Securities, subject to such adjustments as the Representative in its discretion shall make to eliminate any sales or purchases of Option Underwritten Securities in an amount other than whole dollars.

(c) Payment. Payment of the purchase price for, and delivery of, the Initial Underwritten Securities shall be made at the offices of Sidley ▇▇▇▇▇▇ ▇▇▇▇▇ & ▇▇▇▇ LLP, ▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, or at such other place as shall be agreed upon by the Representative and the Company, at 9:00 A.M. (Eastern time) on the third business day after the date of the applicable Terms Agreement (unless postponed in accordance with the provisions of Section 10 hereof), or such other time not later than ten business days after such date as shall be agreed upon by the Representative and the Company (such time and date of payment and delivery being herein called the “Closing Time”). In addition, in the event that the Underwriters have exercised their option, if any, to purchase any or all of the Option Underwritten Securities, payment of the purchase price for, and delivery of such Option Underwritten Securities, shall be made at the above-mentioned offices of Sidley ▇▇▇▇▇▇ ▇▇▇▇▇ & ▇▇▇▇ LLP, or at such other place as shall be agreed upon by the Representative and the Company, on the relevant Date of Delivery as specified in the notice from the Representative to the Company.

Payment shall be made to the Company by wire transfer of immediately available funds to a bank account designated by the Company, against delivery to the Representative for the respective accounts of the Underwriters of the Underwritten Securities to be purchased by them. It is understood that each Underwriter has authorized the Representative, for its account, to accept delivery of, receipt for, and make payment of the purchase price for, the Underwritten Securities which it has severally agreed to purchase. The Representative may for itself and not as representative of the Underwriters, may (but shall not be obligated to) make payment of the purchase price for the Underwritten Securities to be purchased by any Underwriter whose funds have not been received by the Closing Time or the relevant Date of Delivery, as the case may be, but such payment shall not relieve such Underwriter from its obligations hereunder.

(d) Denominations; Registration. The Underwritten Securities or certificates for the Underwritten Securities, as applicable, shall be in such denominations and registered in such

names as the Representative may request in writing at least two full business days prior to the Closing Time or the relevant Date of Delivery, as the case may be. The Underwritten Securities or certificates for the Underwritten Securities, as applicable, will be made available for examination and packaging by the Representative in The City of New York, or at such other place as shall be agreed upon by the Representative and the Company, not later than 10:00 A.M. (Eastern time) on the business day prior to the Closing Time or the relevant Date of Delivery, as the case may be.

SECTION 3. Covenants of the Company and the Guarantors. Each of the Company and the Guarantors covenants with the Representative and with each Underwriter named in the applicable Terms Agreement, as follows:

(a) Compliance with Securities Regulations and Commission Requests. The Company, subject to Section 3(b), will comply with the requirements of Rule 430A of the 1933 Act Regulations and/or Rule 434 of the 1933 Act Regulations, if and as applicable, and will notify the Representative(s) promptly, and confirm the notice in writing, of (i) the effectiveness of any post-effective amendment to the Registration Statement or the filing of any supplement or amendment to the Prospectus, (ii) the receipt of any comments from the Commission, (iii) any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectus or for additional information, and (iv) the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any order preventing or suspending the use of any preliminary prospectus, or of the suspension of the qualification of the Underwritten Securities for offering or sale in any jurisdiction, or of the initiation or threatening of any proceedings for any of such purposes. The Company will promptly effect the filings necessary pursuant to Rule 424 and will take such steps as it deems necessary to ascertain promptly whether any Prospectus transmitted for filing under Rule 424 was received for filing by the Commission and, in the event that it was not, it will promptly file the Prospectus. The Company and the Guarantors will use their best efforts to prevent the issuance of any stop order and, if any stop order is issued, to obtain the lifting thereof as soon as practicable.

(b) Filing of Amendments. The Company will give the Representative notice of its intention to file or prepare any amendment to the Registration Statement (including any filing under Rule 462(b) of the 1933 Act Regulations) or any amendment, supplement or revision to either the prospectus included in the Registration Statement at the time it became effective or to the Prospectus, whether pursuant to the 1933 Act, the 1934 Act or otherwise, will furnish the Representative with copies of any such documents a reasonable amount of time prior to such proposed filing or use, as the case may be, and will not file or use any such document to which the Representative or counsel for the Underwriters shall reasonably object.

(c) Delivery of Registration Statements. The Company has furnished or will deliver to the Representative and counsel for the Underwriters, without charge, signed or conformed copies of the Registration Statement as originally filed and of each amendment thereto (including exhibits filed therewith or incorporated by reference therein and documents incorporated or deemed to be incorporated by reference therein) and signed or conformed copies of all consents and certificates of experts, and will also deliver to the Representative, without charge, a conformed copy of the Registration Statement as originally filed and of each amendment thereto

(without exhibits) for each of the Underwriters. Copies of the Registration Statement and each amendment thereto furnished to the Underwriters will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to ▇▇▇▇▇, except to the extent permitted by Regulation S-T.

(d) Delivery of Prospectuses. The Company will deliver to each Underwriter, without charge, as many copies of each preliminary prospectus as such Underwriter may reasonably request, and the Company hereby consents to the use of such copies for purposes permitted by the 1933 Act. The Company will furnish to each Underwriter, without charge, during the period when the Prospectus is required under the 1933 Act or the 1934 Act to be delivered to investors in connection with sales of the Securities, such number of copies of the Prospectus as such Underwriter may reasonably request. The Prospectus and any amendments or supplements thereto furnished to the Underwriters will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to ▇▇▇▇▇, except to the extent permitted by Regulation S-T.

(e) Continued Compliance with Securities Laws. Each of the Company and the Guarantors will comply with the 1933 Act and the 1933 Act Regulations and the 1934 Act and the 1934 Act Regulations so as to permit the completion of the distribution of the Underwritten Securities as contemplated in this Underwriting Agreement and the applicable Terms Agreement and in the Registration Statement and the Prospectus. If at any time when the Prospectus is required under the 1933 Act or the 1934 Act to be delivered to investors in connection with sales of the Securities any event shall occur or condition shall exist as a result of which it is necessary, in the reasonable opinion of counsel for the Underwriters or for the Company and the Guarantors, to amend the Registration Statement in order that the Registration Statement will 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 or to amend or supplement the Prospectus in order that the Prospectus will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances existing at the time it is delivered to a purchaser, or if it shall be necessary, in the opinion of such counsel, at any such time to amend the Registration Statement or amend or supplement the Prospectus in order to comply with the requirements of the 1933 Act or the 1933 Act Regulations, the Company and the Guarantors will promptly prepare and file with the Commission, subject to Section 3(b), such amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement or the Prospectus comply with such requirements, and the Company and the Guarantors will furnish to the Underwriters, without charge, such number of copies of such amendment or supplement as the Underwriters may reasonably request.

(f) Blue Sky Qualifications. Each of the Company and the Guarantors will use its best efforts, in cooperation with the Underwriters, to qualify the Underwritten Securities for offering and sale under the applicable securities laws of such states and other jurisdictions (domestic or foreign) as the Representative may designate and to maintain such qualifications in effect as long as may be necessary to complete the distribution of the Underwritten Securities; provided, however, that neither the Company nor any Guarantor shall be obligated to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in

respect of doing business in any jurisdiction in which it is not otherwise so subject. In each jurisdiction in which the Underwritten Securities have been so qualified, each of the Company and the Guarantors will file such statements and reports as may be required by the laws of such jurisdiction.

(g) Earnings Statement. The Company will timely file such reports pursuant to the 1934 Act as are necessary in order to make generally available to its securityholders as soon as practicable an earnings statement for the purposes of, and to provide the benefits contemplated by, the last paragraph of Section 11(a) of the 1933 Act.

(h) Use of Proceeds. The Company will use the net proceeds received by it from the sale of the Underwritten Securities in the manner specified in the Prospectus under “Use of Proceeds.”

(j) Restriction on Sale of Securities. Between the date of the applicable Terms Agreement and the Closing Time or such other date specified in such Terms Agreement, the Company will not, without the prior written consent of the Representative, directly or indirectly, issue, sell, offer or contract to sell, grant any option for the sale of, or otherwise dispose of, any debt securities with a maturity in excess of nine months other than borrowings under the Company’s revolving credit facility.

(k) Reporting Requirements. The Company and the Guarantors, during the period when the Prospectus is required to be delivered under the 1933 Act or the 1934 Act, will file all documents required to be filed with the Commission pursuant to the 1934 Act within the time periods required by the 1934 Act and the 1934 Act Regulations.

(l) Additional Guarantors. In the event that a subsidiary of the Company becomes a Guarantor under the Indenture after the date of this Underwriting Agreement, the Company will cause such subsidiary to execute each subsequent Terms Agreement acknowledging the representations, warranties and agreements of such subsidiary as Guarantor under this Underwriting Agreement.

SECTION 4. Payment of Expenses.

It is understood, however, that except as provided in this Section 4, and in Sections 5(n), 6 or 7 hereof, the Underwriters will be responsible for all of their own costs and expenses, including the fees of their counsel, any transfer taxes on the Underwritten Securities upon resale by them and all other expenses incurred by them in connection with any offering of the Underwritten Securities made by the Underwriters.

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission, made in reliance upon and in conformity with written information furnished to the Company or a Guarantor by any Underwriter through the Representative expressly for use in the Registration Statement (or any amendment thereto), including the Rule 430A Information and the Rule 434 Information deemed to be a part thereof, if applicable, or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto); and, provided, further, that this indemnity agreement, insofar as it relates to any preliminary prospectus, shall not inure to the benefit of any Underwriter (or to the benefit of any person who

controls such Underwriter) on account of any loss, liability, claim, damage or expense arising out of the sale of any of the Underwritten Securities by such Underwriter to any person if it shall be established that a copy of the Prospectus (excluding any documents incorporated by reference), as supplemented or amended, if the Company shall have made any supplements or amendments which have been furnished to the Representative, shall not have been sent or given by or on behalf of such Underwriter to such person at or prior to the written confirmation of the sale of Underwritten Securities to such person in any case where such delivery is required by the 1933 Act and the Company satisfied its obligations pursuant to Section 3(b) hereof, if the misstatement or omission leading to such loss, claim, damage or liability was corrected in the Prospectus (excluding any documents incorporated by reference) as amended or supplemented, such correction would have cured the defect giving rise to such loss, liability, claim, damage, or expense and the Prospectus (excluding any documents incorporated by reference) was delivered to such Underwriter a reasonable amount of time in advance of such Underwriter’s delivery of the written confirmation to such person.

(b) Indemnification of Company, Directors and Officers. Each Underwriter severally agrees to indemnify and hold harmless the Company, each Guarantor, their respective directors, each of their officers who signed the Registration Statement, and each person, if any, who controls the Company or any Guarantor within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all losses, liabilities, claims, damages and expenses described in the indemnity contained in Section 6(a), as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), including the Rule 430A Information and the Rule 434 Information deemed to be a part thereof, if applicable, or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representative expressly for use in the Registration Statement (or any amendment thereto) or such preliminary prospectus or the Prospectus (or any amendment or supplement thereto).

(c) Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 6(a) above, counsel to the indemnified parties shall be selected by the Representative, and, in the case of parties indemnified pursuant to Section 6(b) above, counsel to the indemnified parties shall be selected by the Company. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental

agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) Settlement without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(2) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

SECTION 7. Contribution. If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantors, on the one hand, and the Underwriters, on the other hand, from the offering of the Underwritten Securities pursuant to the applicable Terms 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 and the Guarantors, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company and the Guarantors, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Underwritten Securities pursuant to the applicable Terms Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of such Underwritten Securities (before deducting expenses) received by the Company and the Guarantors and the total underwriting discount received by the Underwriters, in each case as set forth on the cover of the Prospectus, or, if Rule 434 is used, the corresponding location on the Term Sheet, bear to the aggregate initial public offering price of such Underwritten Securities as set forth on such cover.

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

The Company, the Guarantors and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Underwritten Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.

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

For purposes of this Section 7, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Underwriter, and each director of the Company or any Guarantor, each officer of the Company or any Guarantor who signed the Registration Statement, and each person, if any, who controls the Company or any Guarantor within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company.

The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the aggregate principal amount of Initial Underwritten Securities set forth opposite their respective names in the applicable Terms Agreement, and not joint.

SECTION 8. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Underwriting Agreement or the applicable Terms Agreement or in certificates of officers of the Company, any Guarantor or any of their respective subsidiaries submitted pursuant hereto or thereto shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or controlling person, or by or on behalf of the Company or any Guarantor, and shall survive delivery of and payment for the Underwritten Securities.

SECTION 9. Termination.

(a) Underwriting Agreement. This Underwriting Agreement (excluding the applicable Terms Agreement) may be terminated for any reason at any time by the Company or by the Representative upon the giving of prior written notice of such termination to the other party hereto.

(b) Terms Agreement. The Representative may terminate the applicable Terms Agreement, by notice to the Company, at any time at or prior to the Closing Time or any relevant Date of Delivery, if (i) there has been, since the time of execution of such Terms Agreement or since the respective dates as of which information is given in the Prospectus, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, or (ii) there has occurred any material adverse change in the financial markets in the United States or in the international financial markets, or any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representative, impracticable or inadvisable to market the Underwritten Securities or to enforce contracts for the sale of the Underwritten Securities, or (iii) trading in any securities of Vectren Corporation, the Company or any Guarantor has been suspended or materially limited by the Commission, the New York Stock Exchange or the American Stock Exchange, or if trading generally on the New York Stock Exchange or the American Stock Exchange or in the Nasdaq National Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by either of said exchanges or by such system or by order of the Commission, the NASD or any other governmental authority, or (iv) there has occurred a material disruption in securities settlement or clearance services in the United States, or (v) a banking moratorium has been declared by either Federal or New York authorities.

(c) Liabilities. If this Underwriting Agreement or the applicable Terms Agreement is terminated pursuant to this Section 9, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 6, 7 and 8 shall survive such termination and remain in full force and effect.

SECTION 10. Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at the Closing Time or the relevant Date of Delivery, as the case may be, to purchase the Underwritten Securities which it or they are obligated to purchase under the applicable Terms Agreement (the “Defaulted Securities”), then the Representative shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representative shall not have completed such arrangements within such 24-hour period, then:

(a) if the number or aggregate principal amount, as the case may be, of Defaulted Securities does not exceed 10% of the number or aggregate principal amount, as the case may be, of Underwritten Securities to be purchased on such date pursuant to such Terms Agreement, the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations under such Terms Agreement bear to the underwriting obligations of all non-defaulting Underwriters, or

(b) if the number or aggregate principal amount, as the case may be, of Defaulted Securities exceeds 10% of the number or aggregate principal amount, as the case may be, of

Underwritten Securities to be purchased on such date pursuant to such Terms Agreement, such Terms Agreement (or, with respect to the Underwriters’ exercise of any applicable over-allotment option for the purchase of Option Underwritten Securities on a Date of Delivery after the Closing Time, the obligations of the Underwriters to purchase, and the Company to sell, such Option Underwritten Securities on such Date of Delivery) shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section 10 shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in (i) a termination of the applicable Terms Agreement or (ii) in the case of a Date of Delivery after the Closing Time, a termination of the obligations of the Underwriters and the Company with respect to the related Option Underwritten Securities, as the case may be, either the Representative or the Company shall have the right to postpone the Closing Time or the relevant Date of Delivery, as the case may be, for a period not exceeding seven days in order to effect any required changes in the Registration Statement or the Prospectus or in any other documents or arrangements.

SECTION 11. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication. Notices to the Underwriters shall be directed to LaSalle Financial Services, Inc. ▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇, ▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇ ▇▇▇▇▇ and notices to the Company shall be directed to it at ▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇ ▇▇▇▇▇, attention of ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇▇.

SECTION 12. Parties. This Underwriting Agreement and the applicable Terms Agreement shall each inure to the benefit of and be binding upon the Company, the Guarantors, the Representative and, upon execution of such Terms Agreement, any other Underwriters and their respective successors. Nothing expressed or mentioned in this Underwriting Agreement or such Terms Agreement is intended or shall be construed to give any person, firm or corporation, other than the parties hereto and their respective successors and the controlling persons and officers and directors referred to in Sections 6 and 7 and their heirs and legal Representative, any legal or equitable right, remedy or claim under or in respect of this Underwriting Agreement or such Terms Agreement or any provision herein or therein contained. This Underwriting Agreement and such Terms Agreement and all conditions and provisions hereof and thereof are intended to be for the sole and exclusive benefit of the parties hereto and thereto and their respective successors, and said controlling persons and officers and directors and their heirs and legal representative, and for the benefit of no other person, firm or corporation. No purchaser of Underwritten Securities from any Underwriter shall be deemed to be a successor by reason merely of such purchase.

SECTION 13. GOVERNING LAW AND TIME. THIS UNDERWRITING AGREEMENT AND ANY APPLICABLE TERMS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME.

SECTION 14. Effect of Headings. The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

SECTION 15. Counterparts. This Agreement may be executed in one or more counterparts and, if executed in more than one counterpart, the executed counterparts hereof shall constitute a single instrument.

SECTION 16. Tax Disclosure. The Company is authorized, subject to applicable law, to disclose any and all aspects of this potential transaction that are necessary to support any U.S. federal income tax benefits expected to be claimed with respect to such transaction, and all materials of any kind (including tax opinions and other tax analyses) related to those benefits, without the Underwriters imposing any limitation of any kind.

If the foregoing is in accordance with your understanding of our agreement, please sign and return to the Company a counterpart hereof, whereupon this Underwriting Agreement, along with all counterparts, will become a binding agreement among the Representative, the Company and the Initial Guarantors in accordance with its terms.

OF THE COMPANY

TO BE DELIVERED PURSUANT TO

SECTION 5(b)

1. The information in the Company’s [list all relevant 1934 Act reports and text in the prospectus supplement] under the caption “Legal Proceedings”, to the extent that it constitutes matters of law, summaries of legal matters or the Company’s charter, bylaws or legal proceedings, or legal conclusions, has been reviewed by me and is correct in all material respects.

2. To the best of my knowledge, neither the Company nor any of its subsidiaries is in violation of its charter or by-laws and no default by the Company or any of its subsidiaries exists in the due performance or observance of any obligation, agreement, covenant or condition contained in any contract, indenture, mortgage, loan agreement, note, lease or other agreement or instrument that is described or referred to in the Registration Statement or the Prospectus or filed or incorporated by reference as an exhibit to the Registration Statement, except for defaults which individually or in the aggregate would not have a Material Adverse Effect.

3. To the best of my knowledge, there are no franchises, contracts, indentures, mortgages, loan agreements, notes, leases or other instruments required to be described or referred to in the Registration Statement or the Prospectus or to be filed as exhibits thereto other than those described or referred to therein or filed or incorporated by reference as exhibits thereto, and the descriptions thereof or references thereto are correct in all material respects.

4. To the best of my knowledge, there are no statutes or regulations that are required to be described in the Prospectus that are not described as required.

EXHIBIT C

FORM OF OPINION OF COMPANY’S COUNSEL

TO BE DELIVERED PURSUANT TO

SECTION 5(c)

1. The Company has been duly incorporated and is validly existing as a corporation under the laws of the State of Indiana.

2. The Company has corporate power and authority to own, lease and operate its properties and to conduct its business as described in the Prospectus and to enter into and perform its obligations under, or as contemplated under, the Underwriting Agreement, the applicable Terms Agreement, the Indenture and the Underwritten Securities.

3. The Company is duly qualified as a foreign corporation to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure to so qualify or be in good standing would not result in a Material Adverse Effect.

4. The authorized, issued and outstanding shares of capital stock of the Company are as set forth in the column entitled “Actual” under the caption “Capitalization” in the Prospectus (except for subsequent issuances thereof, if any, contemplated under the Underwriting Agreement). All of the issued and outstanding shares of capital stock of the Company have been duly authorized and validly issued by the Company and are fully paid and non-assessable, and none of such shares were issued in violation of preemptive or other similar rights of any securityholder of the Company.

5. Each Guarantor has been duly incorporated and is validly existing as a corporation, and where applicable, in good standing under the laws of the jurisdiction of its incorporation, has corporate power and authority to own, lease and operate its properties and to conduct its business as described in the Prospectus and to enter into and perform its obligations under, or as contemplated under, this Underwriting Agreement, the applicable Terms Agreement and its Guarantee and is duly qualified as a foreign corporation to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure to so qualify or be in good standing would not result in a Material Adverse Effect. All of the issued and outstanding capital stock of each Guarantor has been duly authorized and is validly issued, fully paid and non-assessable and, to the best of our knowledge, is owned by the Company, directly or through subsidiaries, free and clear of any security interest, mortgage, pledge, lien, encumbrance, claim or equity. None of the outstanding shares of capital stock of any Guarantor was issued in violation of preemptive or other similar rights of any securityholder of such Guarantor.

6. The Underwritten Securities have been duly authorized by the Company for issuance and sale pursuant to the Underwriting Agreement and the applicable Terms Agreement. The Underwritten Securities, when issued and authenticated in the manner provided for in the

C-1

Indenture and delivered against payment of the consideration therefor specified in such Terms Agreement, will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, except as the enforcement thereof may be limited by bankruptcy, insolvency (including, without limitation, all laws relating to fraudulent transfers), reorganization, moratorium or other similar laws affecting the enforcement of creditors’ rights generally or by general equitable principles (regardless of whether enforcement is considered in a proceeding in equity or at law), and except further as enforcement thereof may be limited by requirements that a claim with respect to any Underwritten Securities payable in a foreign currency (or a foreign currency judgment in respect of such claim) be converted into U.S. dollars at a rate of exchange prevailing on a date determined pursuant to applicable law or by governmental authority to limit, delay or prohibit the making of payments outside the United States.

The Company is a “holding company” (within the meaning of the Public Utility Holding Company Act of 1935, as amended (the “PUHC Act”)) which is exempt from being required to seek approval to perform its obligations under the Underwriting Agreement, the applicable Terms Agreement, the Indenture or the Underwritten Securities pursuant to Rule 2 of the rules and regulations promulgated pursuant to the PUHC Act.

Further, although we are not passing upon and do not assume any responsibility for, the accuracy and completeness of the statements (except as covered by (4), (10), (11), (16) and (17)) contained in the Registration Statement, Prospectus, or any amendment or supplement thereto, including the Rule 430A Information and Rule 434 Information (if applicable), we advise you, on the basis of the discussions and inquiries concerning various legal and related subjects and reviews of and reports on certain corporate records, documents and proceedings and conferences with representatives of the Company at which certain portions of the Registration Statement and the Prospectus were discussed (relying as to certain factual matters upon representations of the Company), nothing has come to our attention that would lead us to believe that the Registration Statement (including any Rule 462(b) Registration Statement) or any post-effective amendment thereto (except for financial statements (including statistical information included in such financial statements), notes and supporting schedules thereto and other financial data included therein or omitted therefrom and for the Form T-1, as to which we make no statement), at the time the Registration Statement (including any Rule 462(b) Registration Statement) or any post-effective amendment thereto (including the filing of the Company’s Annual Report on Form 10-K with the Commission) became effective or at the date of the applicable Terms Agreement, 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 or that the Prospectus or any amendment or supplement thereto (except for financial statements (including statistical information included in such financial statements), notes and supporting schedules thereto and other financial data included therein or omitted therefrom, as to which we make no statement), at the time the Prospectus was issued, at the time any such amended or supplemented prospectus was issued or at the Closing Time, 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.

In rendering such opinion, such counsel may rely, as to matters of fact (but not as to legal conclusions), to the extent they deem proper, on certificates of responsible officers of the Company, the Guarantors and public officials. Such opinion shall not state that it is to be governed or qualified by, or that it is otherwise subject to, any treatise, written policy or other document relating to legal opinions, including, without limitation, the Legal Opinion Accord of the ABA Section of Business Law (1991).
