To Each of the Purchasers Listed in

the Attached Schedule A:

Ladies and Gentlemen:

Vectren Capital, Corp., an Indiana corporation (the “Company”), and Vectren Corporation, an Indiana corporation (“Vectren” and, together with the Company, the “Obligors”), agree with each of the purchasers whose names appear at the end hereof (each, a “Purchaser” and, collectively, the “Purchasers”) as follows:

Section 1. Authorization of Notes.

The Company will authorize the issue and sale, in two series, of $125,000,000 aggregate principal amount of its senior notes, of which $75,000,000 aggregate principal amount shall be its 3.48% Guaranteed Senior Notes, Series A due December 15, 2017 (the “Series A Notes”), and $50,000,000 aggregate principal amount shall be its 4.53% Guaranteed Senior Notes, Series B due December 15, 2025 (the “Series B Notes”, and together with the Series A Notes, the “Notes”, such term to include any such notes issued in substitution therefor pursuant to Section 14). The Series A Notes and the Series B Notes shall be substantially in the forms set out in Exhibits 1-A and 1-B, respectively. Due and punctual payment of the Guaranteed Obligations (as defined herein) will be unconditionally guaranteed by Vectren (the “Guarantee”) as set forth in this Agreement. Certain capitalized terms used in this Agreement are defined in Schedule B; references to a “Schedule” or an “Exhibit” are, unless otherwise specified, to a Schedule or an Exhibit attached to this Agreement.

Section 2. Sale and Purchase of Notes.

Subject to the terms and conditions of this Agreement, the Company will issue and sell to each Purchaser, and each Purchaser will purchase from the Company, at the Closing provided for in Section 3, Notes of the respective series and in the principal amount specified opposite such Purchaser’s name in Schedule A at the purchase price of 100% of the principal amount thereof. The Purchasers’ obligations hereunder are several and not joint obligations, and no Purchaser

Note Purchase Agreement

Vectren Capital, Corp.

shall have any liability to any Person for the performance or non-performance of any obligation by any other Purchaser hereunder.

Section 3. Closing.

The execution and delivery of the Note Purchase Agreement shall occur at the offices of Chapman and Cutler LLP, 111 W. Monroe Street, Chicago, Illinois 60603 at 10:00 a.m., Chicago time, on September 9, 2010 (the “Execution Date”). The sale and purchase of the Notes to be purchased by each Purchaser shall occur at the offices of Chapman and Cutler LLP, 111 W. Monroe Street, Chicago, Illinois 60603 at 10:00 a.m., Chicago time, at a closing (the “Closing”) on December 15, 2010 or on such other Business Day thereafter as may be agreed upon by the Company and the Purchasers, but not later than December 23, 2010. At the Closing the Company will deliver to each Purchaser the Notes to be purchased by such Purchaser in the form of a single Note for each series to be purchased by such Purchaser (or such greater number of Notes in denominations of at least $1,000,000, or any amount in excess thereof which is an integral multiple of $250,000, as such Purchaser may request) dated the date of the Closing and registered in such Purchaser’s name (or in the name of its nominee), against delivery by such Purchaser to the Company or its order of immediately available funds in the amount of the purchase price therefor by wire transfer of immediately available funds for the account of the Company to account number 5800169103 at Bank of America, N.A., New York, New York, ABA No. 026009593. If at the Closing the Company shall fail to tender such Notes to any Purchaser as provided above in this Section 3, or any of the conditions specified in Section 4 shall not have been fulfilled to such Purchaser’s satisfaction, such Purchaser shall, at its election, be relieved of all further obligations under this Agreement, without thereby waiving any rights such Purchaser may have by reason of such failure or such nonfulfillment.

Section 4. Conditions to Closing.

Each Purchaser’s obligation to purchase and pay for the Notes to be sold to such Purchaser at the Closing is subject to the fulfillment to such Purchaser’s satisfaction, prior to or at the Closing, of the following conditions:

Section 4.1. Representations and Warranties. The representations and warranties of the Obligors in this Agreement shall be correct when made and at the time of the Closing, except for failures to be so correct which individually or in the aggregate could not reasonably be expected to result in a Material Adverse Effect; provided, however, that representations and warranties containing a Material Adverse Effect or other materiality qualifier shall be correct in all respects.

Section 4.2. Performance; No Default. Each Obligor shall have performed and complied with all agreements and conditions contained in this Agreement required to be performed or complied with by it prior to or at the Closing and after giving effect to the issue and sale of the Notes (and the application of the proceeds thereof as contemplated by Section 5.14) no Default or Event of Default shall have occurred and be continuing. Neither the Company nor Vectren (as applicable) shall have entered into any transaction since the date of the Memorandum (as defined herein) that would have been prohibited by Section 10.1, 10.2, 10.5, 10.6, 10.7 or 10.8 hereof had such Sections applied since such date.

Section 4.5. Purchase Permitted By Applicable Law, Etc. On the date of the Closing such Purchaser’s purchase of Notes shall (i) be permitted by the laws and regulations of each jurisdiction to which such Purchaser is subject, without recourse to provisions (such as section 1405(a)(8) of the New York Insurance Law) permitting limited investments by insurance companies without restriction as to the character of the particular investment, (ii) not violate any applicable law or regulation (including, without limitation, Regulation T, U or X of the Board of Governors of the Federal Reserve System) and (iii) not subject such Purchaser to any tax, penalty or liability under or pursuant to any applicable law or regulation, which law or regulation was not in effect on the date hereof. If requested by such Purchaser, such Purchaser shall have received an Officer’s Certificate from Vectren certifying as to such matters of fact as such Purchaser may reasonably specify to enable such Purchaser to determine whether such purchase is so permitted.

Each of the Company and Vectren represents and warrants to each Purchaser (only to the extent applicable to itself and, if specified, its Subsidiaries) as follows as of the date hereof or, if the representation or warranty speaks as of a different date, as of such date:

Section 5.1. Organization; Power and Authority. Each of the Company and Vectren is a corporation duly organized and validly existing under the laws of its jurisdiction of incorporation, and is duly qualified as a foreign corporation and is in good standing in each jurisdiction in which such qualification is required by law, other than those jurisdictions as to which the failure to be so qualified or in good standing could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. Each of the Company and Vectren has the corporate power and authority to own or hold under lease the properties it purports to own or hold under lease, to transact the business it transacts and proposes to transact, to execute and deliver this Agreement and the Notes (in the case of the Company) and this Agreement and the Guarantee (in the case of Vectren), and to perform the provisions hereof and thereof.

Section 5.2. Authorization, Etc. This Agreement and the Notes have been duly authorized by all necessary corporate action on the part of the Company, and this Agreement constitutes, and upon execution and delivery thereof each Note will constitute, a legal, valid and binding obligation of the Company enforceable against the Company in accordance with its terms, and this Agreement and the Guarantee have been duly authorized by all necessary corporate action on the part of Vectren and constitute legal, valid and binding obligations of

Note Purchase Agreement

Vectren Capital, Corp.

Vectren enforceable against Vectren in accordance with their respective terms, except, in each case, as such enforceability may be limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting the enforcement of creditors’ rights generally and (ii) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

Section 5.3. Disclosure. The Company and Vectren, through their agent, J.P. Morgan Securities Inc., have delivered to each Purchaser a copy of a Private Placement Memorandum, dated July 2010 (including the SEC Reports incorporated by reference therein, the “Memorandum”), relating to the transactions contemplated hereby. The Memorandum fairly describes, in all material respects, the general nature of the business and principal properties of the Company, Vectren and the Restricted Subsidiaries. This Agreement, the Memorandum (including the SEC Reports and the financial statements included therein) and the documents, certificates or other writings delivered to the Purchasers by or on behalf of the Company or Vectren, as applicable, in connection with the transactions contemplated hereby (this Agreement, the Memorandum and such documents, certificates or other writings delivered to each Purchaser being referred to, collectively, as the “Disclosure Documents”), taken as a whole, do not contain any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein not misleading in light of the circumstances under which they were made. Except as disclosed in the Disclosure Documents delivered to the Purchasers on or prior to the date of this Agreement, since December 31, 2009, there has been no change in the financial condition, operations, business, properties or prospects of the Company, Vectren or any Restricted Subsidiary except changes that individually or in the aggregate would not reasonably be expected to have a Material Adverse Effect. There is no fact known to the Company or Vectren that would reasonably be expected to have a Material Adverse Effect that has not been set forth herein or in the Disclosure Documents.

Section 5.4. Organization and Ownership of Shares of Subsidiaries; Affiliates. (a) Schedule 5.4 contains (except as noted therein) complete and correct lists of (i) Vectren’s Subsidiaries, showing, as to each Subsidiary, the correct name thereof, the jurisdiction of its organization, and the percentage of shares of each class of its capital stock or similar equity interests outstanding owned by Vectren and each other Subsidiary and whether such Subsidiary is a Restricted Subsidiary or an Unrestricted Subsidiary, (ii) Vectren’s Affiliates, other than Subsidiaries, and (iii) Vectren’s directors and senior officers.

(b)All of the outstanding shares of capital stock or similar equity interests of each Subsidiary shown in Schedule 5.4 as being owned by Vectren and its Subsidiaries have been validly issued, are fully paid and nonassessable and are owned by Vectren or another Subsidiary free and clear of any Lien (except as otherwise disclosed in Schedule 5.4).

(c)Each Subsidiary identified in Schedule 5.4 is a corporation or other legal entity duly organized, validly existing and in good standing (to the extent applicable) under the laws of its jurisdiction of organization, and is duly qualified as a foreign corporation or other legal entity and is in good standing in each jurisdiction in which such qualification is required by law, other than those jurisdictions as to which the failure to be so qualified or in good standing could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. Each

Note Purchase Agreement

Vectren Capital, Corp.

such Subsidiary has the corporate or other power and authority to own or hold under lease the properties it purports to own or hold under lease and to transact the business it transacts and proposes to transact.

(d)No Subsidiary is a party to, or otherwise subject to any legal, regulatory, contractual, or other restriction (other than the agreements listed on Schedule 5.4 and customary limitations imposed by corporate law and fraudulent conveyance statutes or similar statutes and applicable restrictions contained in section 305(a) of the Federal Power Act, as amended), restricting the ability of such Subsidiary to pay dividends out of profits or make any other similar distributions of profits to Vectren or any of its Subsidiaries that owns outstanding shares of capital stock or similar equity interests of such Subsidiary.

Section 5.5. Financial Statements. Vectren has delivered to each Purchaser copies of the audited financial statements of Vectren for the years ended December 31, 2005 through December 31, 2009, inclusive. All of said financial statements and all of the financial statements included in the SEC Reports (including in each case the related schedules and notes) fairly present in all material respects the consolidated financial position of Vectren and its Subsidiaries as of the respective dates specified in such financial statements and the consolidated results of their operations and cash flows for the respective periods so specified and have been prepared in accordance with U.S. GAAP consistently applied throughout the periods involved except as set forth in the notes thereto (subject, in the case of any interim financial statements, to normal year-end adjustments). Vectren and its Subsidiaries do not have any Material liabilities that are not disclosed on such audited or unaudited financial statements included in the SEC Reports or otherwise disclosed in the Disclosure Documents.

Section 5.6. Compliance with Laws, Other Instruments, Etc. The execution, delivery and performance by the Company of this Agreement and the Notes and by Vectren of this Agreement and the Guarantee will not (i) contravene, result in any breach of, or constitute a default under, or result in the creation of any Lien in respect of any property of the Company or Vectren, as the case may be, or any Subsidiary, under any indenture, mortgage, deed of trust, loan, purchase or credit agreement, lease, corporate charter or by-laws, or any other agreement or instrument to which the Company, Vectren or any Subsidiary is bound or by which the Company, Vectren or any Subsidiary or any of their respective properties may be bound or affected, (ii) conflict with or result in a breach of any of the terms, conditions or provisions of any order, judgment, decree, or ruling of any court, arbitrator or Governmental Authority applicable to the Company, Vectren or any Subsidiary or (iii) violate any provision of any statute or other rule or regulation of any Governmental Authority applicable to the Company, Vectren or any Subsidiary (including, without limitation, PUHCA or the Federal Power Act, as amended).

Section 5.7. Governmental Authorizations, Etc. No consent, approval or authorization of, or registration, filing or declaration with, any Governmental Authority is required in connection with the execution, delivery or performance by the Company of this Agreement or the Notes or by Vectren of this Agreement or the Guarantee (including, without limitation, any thereof under PUHCA, the Natural Gas Act or the Federal Power Act, each as amended).

Note Purchase Agreement

Vectren Capital, Corp.

Section 5.8. Litigation; Observance of Agreements, Statutes and Orders. (a) There are no actions, suits, investigations or proceedings pending or, to the knowledge of the Company or Vectren, threatened against or affecting the Company, Vectren or any Restricted Subsidiary or any property of the Company, Vectren or any Restricted Subsidiary in any court or before any arbitrator of any kind or before or by any Governmental Authority that, individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect.

(b)None of the Company, Vectren or any Restricted Subsidiary is in default under any term of any agreement or instrument to which it is a party or by which it is bound, or any order, judgment, decree or ruling of any court, arbitrator or Governmental Authority or is in violation of any applicable law, ordinance, rule or regulation (including without limitation Environmental Laws or the USA Patriot Act) of any Governmental Authority, which default or violation, individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect.

Section 5.9. Taxes. Vectren and each Subsidiary have filed all tax returns that are required to have been filed in any jurisdiction, and have paid all taxes shown to be due and payable on such returns and all other taxes and assessments levied upon them or their properties, assets, income or franchises, to the extent such taxes and assessments have become due and payable and before they have become delinquent, except for any taxes and assessments (i) the amount of which is not individually or in the aggregate Material or (ii) the amount, applicability or validity of which is currently being contested in good faith by appropriate proceedings and with respect to which Vectren or a Subsidiary, as the case may be, has established adequate reserves in accordance with U.S. GAAP. Vectren does not know of any basis for any other tax or assessment that would have a Material Adverse Effect. The charges, accruals and reserves on the books of Vectren and its Subsidiaries in respect of taxes for all fiscal periods are adequate. The Internal Revenue Service (IRS) has conducted examinations of Vectren’s U.S. federal income tax returns for tax years through December 31, 2005. The State of Indiana, Vectren’s primary state tax jurisdiction, has conducted examinations of state income tax returns for tax years through December 31, 2007. The statutes of limitations for assessment of federal and Indiana income tax have expired with respect to tax years through 2002.

Section 5.10. Title to Property; Leases. Vectren and each Restricted Subsidiary have good and sufficient title to their respective properties that individually or in the aggregate are Material, including all such properties reflected in the most recent audited balance sheets referred to in Section 5.5 or purported to have been acquired by Vectren or any Restricted Subsidiary after said date (except as sold or otherwise disposed of in the ordinary course of business), in each case free and clear of Liens prohibited by this Agreement. All leases that Vectren or any Restricted Subsidiary is party to as lessee and that individually or in the aggregate are Material are valid and subsisting and are in full force and effect in all material respects.

Section 5.11. Licenses, Permits, Etc. Except as disclosed in Schedule 5.11, (a) Vectren and each Restricted Subsidiary own or possess all licenses, permits, franchises, authorizations, patents, copyrights, proprietary software, service marks, trademarks and trade names, or rights thereto, that individually or in the aggregate are Material, without known conflict with the rights of others;

Note Purchase Agreement

Vectren Capital, Corp.

(b)to the best knowledge of Vectren, no product or service of Vectren or any Restricted Subsidiary infringes in any material respect any license, permit, franchise, authorization, patent, copyright, proprietary software, service mark, trademark, trade name or other right owned by any other Person; and

(c)to the best knowledge of Vectren, there is no Material violation by any Person of any right of Vectren or any Restricted Subsidiary with respect to any patent, copyright, proprietary software, service mark, trademark, trade name or other right owned or used by Vectren or any Restricted Subsidiary.

Section 5.12. Compliance with ERISA. (a) Vectren and each ERISA Affiliate have operated and administered each Plan in compliance with all applicable laws except for such instances of noncompliance as have not resulted in and could not reasonably be expected to result in a Material Adverse Effect. Neither Vectren nor any ERISA Affiliate has incurred any liability pursuant to Title I or IV of ERISA or the penalty or excise tax provisions of the Code relating to employee benefit plans (as defined in section 3 of ERISA), and no event, transaction or condition has occurred or exists that could reasonably be expected to result in the incurrence of any such liability by Vectren or any ERISA Affiliate, or in the imposition of any Lien on any of the rights, properties or assets of Vectren or any ERISA Affiliate, in either case pursuant to Title I or IV of ERISA or to such penalty or excise tax provisions or to section 436 or 430 of the Code or section 4068 of ERISA, other than such liabilities or Liens as would not be individually or in the aggregate Material.

(b)The present value of the aggregate benefit liabilities under each of the Plans (other than Multiemployer Plans), determined as of the end of such Plan’s most recently ended plan year on the basis of the assumptions used in preparing the audited financial statements included in Vectren’s Form 10-K for the fiscal year ending December 31, 2009, did not exceed the aggregate current value of the assets of such Plan allocable to such benefit liabilities by more than $100,000,000. The term “benefit liabilities” has the meaning specified in section 4001 of ERISA and the terms “current value” and “present value” have the meaning specified in section 3 of ERISA.

Note Purchase Agreement

Vectren Capital, Corp.

first sentence of this Section 5.12(e) is made in reliance upon and subject to the accuracy of such Purchaser’s representation in Section 6.2 as to the sources of the funds used to pay the purchase price of the Notes to be purchased by such Purchaser.

Section 5.13. Private Offering by the Company. Neither the Company nor anyone acting on its behalf has offered the Notes or any similar securities for sale to, or solicited any offer to buy any of the same from, or otherwise approached or negotiated in respect thereof with, any Person other than the Purchasers and not more than __ other Institutional Investors, each of which has been offered the Notes at a private sale for investment. Neither the Company nor anyone acting on its behalf has taken, or will take, any action that would subject the issuance or sale of the Notes to the registration requirements of section 5 of the Securities Act or to the registration requirements of any securities or blue sky laws of any applicable jurisdiction.

Section 5.14. Use of Proceeds; Margin Regulations.

Margin stock does not constitute more than 10% of the value of the consolidated assets of Vectren and its Subsidiaries and Vectren does not have any present intention that margin stock will constitute more than 10% of the value of such assets.

None of the Company, Vectren or any Restricted Subsidiary is in default, and no waiver of default is currently in effect, in the payment of any principal or interest on any Indebtedness of the Company, Vectren or such Restricted Subsidiary and no event or condition exists with respect to any Indebtedness of the Company, Vectren or any Restricted Subsidiary that would permit (or that with notice or the lapse of time, or both, would permit) one or more Persons to cause such Indebtedness to become due and payable before its stated maturity or before its regularly scheduled dates of payment.

(b)Except as disclosed in Schedule 5.15, none of the Company, Vectren or any Restricted Subsidiary has agreed or consented to cause or permit in the future (upon the

(c)Neither the Company, Vectren nor any Subsidiary is a party to, or otherwise subject to any provision contained in, any instrument evidencing Indebtedness of the Company, Vectren or such Subsidiary, as applicable, any agreement relating thereto or any other agreement (including, but not limited to, its charter or other organizational document) which limits the amount of, or otherwise imposes restrictions on the incurring of, Indebtedness of the Company or Vectren, as applicable, except as specifically indicated in Schedule 5.15.

Section 5.16. Foreign Assets Control Regulations and Foreign or Enemy Status. (a) Neither the sale of the Notes by the Company hereunder nor the Company’s use of the proceeds thereof nor the issuance by Vectren of the Guarantee will violate the Trading with the Enemy Act, as amended, or any of the foreign assets control regulations of the United States Treasury Department (31 CFR, Subtitle B, Chapter V, as amended) or any enabling legislation or executive order relating thereto.

The Company, Vectren and its Subsidiaries are in compliance, in all material respects, with the USA Patriot Act.

(c)No part of the proceeds from the sale of the Notes hereunder will be used, directly or indirectly, for any payments to any governmental official or employee, political party, official of a political party, candidate for political office, or anyone else acting in an official capacity, in order to obtain, retain or direct business or obtain any improper advantage, in violation of the United States Foreign Corrupt Practices Act of 1977, as amended, assuming in all cases that such Act applies to the Company and Vectren and its Subsidiaries.

Section 5.17. Status under Certain Statutes. Neither Vectren nor any Subsidiary is subject to regulation under the Investment Company Act of 1940, as amended, the ICC Termination Act of 1995, as amended, or the Federal Power Act, as amended, other than Southern Indiana Gas and Electric Company which is subject to regulation under the Federal Power Act.

All liabilities of Vectren under the Guarantee constitute direct, unconditional and general obligations of Vectren and rank in right of payment either pari passu with or senior to all other unsecured Indebtedness of Vectren.

The Company may, at its option, upon notice as provided below, prepay at any time all, or from time to time any part of, any series of the Notes, in an amount not less than 5% of the aggregate principal amount of the Notes then outstanding in the case of a partial prepayment (or such lesser amount as shall be required to effect a partial prepayment resulting from an offer of prepayment pursuant to Section 10.6), at 100% of the principal amount so prepaid, and the Make-Whole Amount determined for the prepayment date with respect to such principal amount. The Company will give each Holder of Notes written notice of each optional prepayment under this Section 8.2 not less than 30 days and not more than 60 days prior to the date fixed for such prepayment. Each such notice shall specify such date (which shall be a Business Day), the aggregate principal amount of the Notes of such series to be prepaid on such date, the principal amount of each Note held by such Holder to be prepaid (determined in accordance with Section 8.3), and the interest to be paid on the prepayment date with respect to such principal amount being prepaid, and shall be accompanied by a certificate of a Senior Financial Officer as to the estimated applicable Make-Whole Amounts due in connection with such prepayment (calculated as if the date of such notice were the date of the prepayment), setting forth the details of such computation. Two Business Days prior to such prepayment, the Company shall deliver to each Holder of Notes a certificate of a Senior Financial Officer specifying the calculation of such Make-Whole Amounts as of the specified prepayment date.

Section 8.3. Allocation of Certain Partial Prepayments. In the case of each partial prepayment of any series of the Notes pursuant to Section 8.2, the principal amount of the Notes to be prepaid shall be allocated among all of the Notes (of such series) at the time outstanding in proportion, as nearly as practicable, to the respective unpaid principal amounts thereof not theretofore called for prepayment.

Section 8.4. Maturity; Surrender, Etc. In the case of each prepayment of Notes pursuant to this Section 8, the principal amount of each Note to be prepaid shall mature and become due and payable on the date fixed for such prepayment (which shall be a Business Day), together with interest on such principal amount accrued to such date and the applicable Make-Whole Amount, if any. From and after such date, unless the Company shall fail to pay such principal amount when so due and payable, together with the interest and Make-Whole Amount, if any, as aforesaid, interest on such principal amount shall cease to accrue. Any Note paid or prepaid in full shall be surrendered to the Company and cancelled and shall not be reissued, and no Note shall be issued in lieu of any prepaid principal amount of any Note.

Section 8.5. Purchase of Notes. Neither Obligor will nor will either Obligor permit any Affiliate to purchase, redeem, prepay or otherwise acquire, directly or indirectly, any of the outstanding Notes except upon the payment or prepayment of the Notes in accordance with the terms of this Agreement and the Notes.

Note Purchase Agreement

Vectren Capital, Corp.

by either Obligor or any such Affiliate pursuant to any payment or prepayment of Notes pursuant to any provision of this Agreement and no Notes may be issued in substitution or exchange for any such Notes.

Section 8.6. Make-Whole Amount. The term “Make-Whole Amount” means, with respect to any Note, an amount equal to the excess, if any, of the Discounted Value of the Remaining Scheduled Payments with respect to the Called Principal of such Note over the amount of such Called Principal, provided that the Make-Whole Amount may in no event be less than zero. For the purposes of determining the Make-Whole Amount, the following terms have the following meanings:

“Called Principal” means, with respect to any Note, the principal of such Note that is to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 13.1, as the context requires.

“Discounted Value” means, with respect to the Called Principal of any Note, the amount obtained by discounting all Remaining Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the same periodic basis as that on which interest on the Notes is payable) equal to the Reinvestment Yield with respect to such Called Principal.

“Reinvestment Yield” means, 0.50% plus the yield to maturity calculated by using (i) the yields reported, as of 10:00 A.M. (New York City time) on the second Business Day preceding the Settlement Date on screen “PX-1” on the Bloomberg Financial Market Service (or such other display as may replace Page PX1) on Bloomberg for the most recently issued actively traded on the run U.S. Treasury securities having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date, or (ii) if such yields are not reported as of such time or the yields reported as of such time are not ascertainable (including by way of interpolation), the Treasury Constant Maturity Series Yields reported, for the latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date, in Federal Reserve Statistical Release H.15 (519) (or any comparable successor publication) for actively traded U.S. Treasury securities having a constant maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date.

In the case of each determination under clause (i) or clause (ii), as the case may be, of the preceding paragraph, such implied yield will be determined, if necessary, by (a) converting U.S. Treasury bill quotations to bond-equivalent yields in accordance with accepted financial practice and (b) interpolating linearly between (1) the applicable U.S. Treasury security with the maturity closest to and greater than such Remaining Average Life and (2) the applicable U.S. Treasury security with the maturity closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Note.

Note Purchase Agreement

Vectren Capital, Corp.

“Remaining Average Life” means, with respect to any Called Principal, the number of years (calculated to the nearest one-twelfth year) obtained by dividing (i) such Called Principal into (ii) the sum of the products obtained by multiplying (a) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (b) the number of years (calculated to the nearest one-twelfth year) that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment.

“Remaining Scheduled Payments” means, with respect to the Called Principal of any Note, all payments of such Called Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its scheduled due date, provided that if such Settlement Date is not a date on which interest payments are due to be made under the terms of the Notes, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date pursuant to Section 8.2 or 13.1.

“Settlement Date” means, with respect to the Called Principal of any Note, the date on which such Called Principal is to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 13.1, as the context requires.

Section 8.7. Change in Control. (a) Notice of Change in Control or Control Event. The Company will, within 15 Business Days after any Responsible Officer has knowledge of the occurrence of any Change in Control or Control Event, give written notice of such Change in Control or Control Event to each Holder of Notes unless notice in respect of such Change in Control (or the Change in Control contemplated by such Control Event) shall have been given pursuant to subparagraph (b) of this Section 8.7.

Each of the Company and Vectren covenants (only to the extent applicable to itself and, if specified, its Subsidiaries) that from and after the Closing and for so long as any of the Notes are outstanding:

Section 9.1. Compliance with Law. The Obligors will, and Vectren will cause each of its Subsidiaries to, comply with all laws, ordinances or governmental rules or regulations to which each of them is subject, including, without limitation, ERISA, the USA Patriot Act, Environmental Laws, and will obtain and maintain in effect all licenses, certificates, permits, franchises and other governmental authorizations necessary to the ownership of their respective properties or to the conduct of their respective businesses, in each case to the extent necessary to ensure that non-compliance with such laws, ordinances or governmental rules or regulations or failures to obtain or maintain in effect such licenses, certificates, permits, franchises and other governmental authorizations would not reasonably be expected, individually or in the aggregate, to have a Material Adverse Effect.

Section 9.2. Insurance. The Obligors will, and Vectren will cause each of its Restricted Subsidiaries to, maintain, with financially sound and reputable insurers, insurance with respect to their respective properties and businesses against such casualties and contingencies, of such types, on such terms and in such amounts (including deductibles, co-insurance and self-insurance, if adequate reserves are maintained with respect thereto) as is customary in the case of entities of established reputations engaged in the same or a similar business and similarly situated.

Section 9.3. Maintenance of Properties. The Obligors will, and Vectren will cause each of its Restricted Subsidiaries to, maintain and keep, or cause to be maintained and kept, their respective properties in good repair, working order and condition (other than ordinary wear and tear), so that the business carried on in connection therewith may be properly conducted at all times, provided that this Section shall not prevent either Obligor or any such Restricted Subsidiary from discontinuing the operation and the maintenance of any of its properties if such discontinuance is desirable in the conduct of its business and Vectren has concluded that such discontinuance would not reasonably be expected, individually or in the aggregate, to have a Material Adverse Effect.

Section 9.4. Payment of Taxes and Claims. The Obligors will, and Vectren will cause each of its Subsidiaries to, file all tax returns required to be filed in any jurisdiction and to pay

Note Purchase Agreement

Vectren Capital, Corp.

and discharge all taxes shown to be due and payable on such returns and all other taxes, assessments, governmental charges, or levies imposed on them or any of their properties, assets, income or franchises, to the extent such taxes, assessments, charges and levies have become due and payable and before they have become delinquent and all claims for which sums have become due and payable that have or might become a Lien on properties or assets of the Company, Vectren or any Subsidiary, provided that neither of the Obligors nor any such Subsidiary need pay any such tax, assessment, charge, levy or claim if (i) the amount, applicability or validity thereof is contested by such Obligor or such Subsidiary on a timely basis in good faith and in appropriate proceedings, and such Obligor or such Subsidiary has established adequate reserves therefor in accordance with U.S. GAAP on the books of such Obligor or such Subsidiary or (ii) the nonpayment of all such taxes, assessments, charges, levies and claims in the aggregate would not have a Material Adverse Effect.

Section 9.5. Entity Existence, Etc. Subject to Section 10.2, the Obligors will at all times preserve and keep in full force and effect their existences as a corporation, partnership or limited liability company, and Vectren will at all times preserve and keep in full force and effect the existence of each of its Restricted Subsidiaries as a corporation, partnership or limited liability company (unless merged into Vectren or a Wholly-Owned Subsidiary) and all rights and franchises of the Obligors and such Restricted Subsidiaries unless, in the good faith judgment of Vectren, the termination of or failure to preserve and keep in full force and effect the existence of any such Restricted Subsidiary (other than the Company), or any such right or franchise would not, individually or in the aggregate, have a Material Adverse Effect.

Section 9.6. Books and Records. Vectren will, and will cause each of its Subsidiaries to, maintain proper books of record and account in conformity with U.S. GAAP and all applicable requirements of any Governmental Authority having legal or regulatory jurisdiction over Vectren or such Subsidiary, as the case may be.

Section 9.9. Subsidiary Guarantors. (a) The Company will cause any Subsidiary which becomes obligated for, or otherwise guarantees, Indebtedness in respect of the Bank Credit Agreement, to deliver to each of the Holders of the Notes (concurrently with the incurrence of any such obligation) the following items:

(i)a duly executed guaranty agreement (the “Subsidiary Guaranty”) in scope, form and substance reasonably satisfactory to the Required Holders;

(b)The Holders of the Notes agree to discharge and release any Subsidiary Guarantor from the Subsidiary Guaranty upon the written request of the Company, provided that (i) such Subsidiary Guarantor has been released and discharged (or will be released and discharged concurrently with the release of such Subsidiary Guarantor under the Subsidiary Guaranty) as an obligor and guarantor under and in respect of the Bank Credit Agreement and the Company so certifies to the Holders of the Notes in a certificate of a Responsible Officer, (ii) at the time of such release and discharge, the Company shall deliver a certificate of a Responsible Officer to the Holders of the Notes stating that no Default or Event of Default exists, and (iii) if any fee or other form of consideration is given to any holder of Indebtedness of the Company for the purpose of such release, Holders of the Notes shall receive equivalent consideration.

(b)Vectren waives presentation to, demand of payment from and protest to the Company of any of the Guaranteed Obligations and also waives notice of protest for nonpayment. Vectren waives notice of any default under the Notes or the Guaranteed Obligations.

(e)Vectren agrees that its Guarantee shall remain in full force and effect until payment in full of the Guaranteed Obligations. The obligations of Vectren hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of

waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of Vectren herein shall not be discharged or impaired or otherwise affected by the failure of any Holder of Notes to assert any claim or demand or to enforce any remedy under this Agreement, the Notes or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of Vectren or would otherwise operate as a discharge of Vectren as a matter of law or equity.

(f)Vectren agrees that its Guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest on any Guaranteed Obligation is rescinded or must otherwise be restored by any Holder upon the bankruptcy or reorganization of the Company or otherwise.

(g)In furtherance of the foregoing and not in limitation of any other right which any Holder has at law or in equity against Vectren by virtue hereof, upon the failure of the Company to pay the principal of or interest on any Guaranteed Obligation (or any Make-Whole Amount) when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, or to perform or comply with any other Guaranteed Obligation, Vectren hereby promises to and shall forthwith pay, or cause to be paid, in cash, to the Holders of Notes an amount equal to the sum of (i) the unpaid principal amount of the Notes, (ii) accrued and unpaid interest on the Notes and (iii) all other monetary obligations of the Company to the Holders of Notes, including any other unpaid principal amount of such Guaranteed Obligations, any Make-Whole Amount, accrued and unpaid interest on such Guaranteed Obligations (but only to the extent not prohibited by law) and any interest on overdue interest at the Default Rate.

(h)Vectren agrees that it shall not be entitled to any right of subrogation in relation to the Holders of Notes in respect of any Guaranteed Obligations guaranteed hereby until payment in full of all Guaranteed Obligations. Vectren further agrees that, as between it, on the one hand, and the Holders of Notes, on the other hand, (i) to the extent permitted by applicable law, the maturity of the Guaranteed Obligations guaranteed hereby may be accelerated as provided in Section 13.1 for the purposes of the Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guaranteed Obligations guaranteed hereby, and (ii) in the event of any declaration of acceleration of such Guaranteed Obligations as provided in Section 13.1, such Guaranteed Obligations (whether or not due and payable) shall forthwith become due and payable by Vectren for the purposes of this Section 11.

(i)Vectren also agrees to pay any and all reasonable costs and expenses (including reasonable attorneys’ fees and expenses) incurred by any Holder of Notes in enforcing any rights under this Section 11.

Section 11.2. Successors and Assigns. This Section 11 shall be binding upon Vectren and its successors and assigns and shall inure to the benefit of the successors and assigns of the Holders of Notes and, in the event of any transfer or assignment of rights by any Holder of

Note Purchase Agreement

Vectren Capital, Corp.

Notes, the rights and privileges conferred upon that party in this Agreement and in the Notes shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Agreement.

Section 11.3. No Waiver. Neither a failure nor a delay on the part of any Holders of Notes in exercising any right, power or privilege under this Section 11 shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Holders of Notes herein expressly specified are cumulative and not exclusive of any other rights, remedies or benefits which the Holders of Notes may have under this Section 11 at law, in equity, by statute or otherwise.

Section 11.4. Modification. No modification, amendment or waiver of any provision of this Section 11, nor the consent to any departure by Vectren therefrom, shall in any event be effective unless the same shall be in writing and signed by each Holder of Notes affected by such modification, amendment or waiver, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice to or demand on Vectren in any case shall entitle Vectren to any other or further notice or demand in the same, similar or other circumstances.

Section 11.5. Non-Impairment. The failure to endorse a Guarantee on any Note shall not affect or impair the validity thereof.

Section 12. Events of Default.

An “Event of Default” shall exist if any of the following conditions or events shall occur and be continuing:

The Company acknowledges, and the parties hereto agree, that each Holder of a Note has the right to maintain its investment in the Notes free from repayment by the Company (except as herein specifically provided for) and that the provision for payment of a Make-Whole Amount by the Company in the event that the Notes are prepaid or are accelerated as a result of an Event of Default, is intended to provide compensation for the deprivation of such right under such circumstances.

Section 13.2. Other Remedies. If any Default or Event of Default has occurred and is continuing, and irrespective of whether any Notes have become or have been declared immediately due and payable under Section 13.1, the Holder of any Note at the time outstanding may proceed to protect and enforce the rights of such Holder by an action at law, suit in equity or other appropriate proceeding, whether for the specific performance of any agreement contained herein or in any Note or in the Guarantee, or for an injunction against a violation of any of the terms hereof or thereof, or in aid of the exercise of any power granted hereby or thereby or by law or otherwise.

Section 13.4. No Waivers or Election of Remedies, Expenses, Etc.

No right, power or remedy conferred by this Agreement or by any Note upon any Holder thereof shall be exclusive of any other right, power or remedy referred to herein or therein or now or hereafter available at law, in equity, by statute or otherwise. Without limiting the obligations of the Company under Section 16, the Company will pay to the Holder of each Note on demand such further amount as shall be sufficient to cover all costs and expenses of

Note Purchase Agreement

Vectren Capital, Corp.

such Holder incurred in any enforcement or collection under this Section 13, including, without limitation, reasonable attorneys’ fees, expenses and disbursements.

Prior to due presentment for registration of transfer, the Person in whose name any Note shall be registered shall be deemed and treated as the owner and Holder thereof for all purposes hereof, and the Company shall not be affected by any notice or knowledge to the contrary. The Company shall give to any Holder of a Note that is an Institutional Investor promptly upon request therefor, a complete and correct copy of the names and addresses of all registered Holders of Notes.

Each such new Note shall be dated and bear interest from the date to which interest shall have been paid on the surrendered Note or dated the date of the surrendered Note if no interest shall have been paid thereon. The Company may require payment of a sum sufficient to cover any stamp tax or governmental charge imposed in respect of any such transfer of Notes. Notes shall not be transferred in denominations of less than $1,000,000 or in any amount in excess thereof which is not an integral multiple of $250,000, provided that if necessary to enable the registration of transfer by a Holder of its entire holding of Notes of a series, one Note of such series may be in a denomination of less than $1,000,000 and in an amount which is not an integral multiple of $250,000. Any transferee, by its acceptance of a Note registered in its name (or the name of its nominee), shall be deemed to have made the representations set forth in Sections 6.1 and 6.2.

(b)in the case of mutilation, upon surrender and cancellation thereof,

within ten Business Days thereafter, the Company at its own expense shall execute and deliver, in lieu thereof, a new Note of the same series, dated and bearing interest from the date to which interest shall have been paid on such lost, stolen, destroyed or mutilated Note or dated the date of such lost, stolen, destroyed or mutilated Note if no interest shall have been paid thereon.

Section 14.4. Legend. Each Note issued on the date of the Closing and each Note issued pursuant to this Section 14 shall bear a legend substantially as follows (until such time as the Company shall reasonably agree that such legend is no longer necessary or advisable):

“This Note has not been registered under the United States Securities Act of 1933, as amended, or any other applicable securities laws and, accordingly, may not be sold or otherwise transferred unless registered or exempt from registration under said act or such other laws.”

Section 15.2. Home Office Payment. So long as any Purchaser or its nominee shall be the Holder of any Note, and notwithstanding anything contained in Section 15.1 or in such Note to the contrary, the Company will pay all sums becoming due on such Note for principal, Make-Whole Amount, if any, and interest by the method and at the address specified for such purpose below such Purchaser’s name in Schedule A, or by such other method or at such other address as such Purchaser shall have from time to time specified to the Company in writing for such purpose, without the presentation or surrender of such Note or the making of any notation thereon, except that upon written request of the Company made concurrently with or reasonably promptly after payment or prepayment in full of any Note, such Purchaser shall surrender such Note for cancellation, reasonably promptly after any such request, to the Company at its principal executive office or at the place of payment most recently designated by the Company pursuant to Section 15.1. Prior to any sale or other disposition of any Note held by a Purchaser or its nominee, such Purchaser will, at its election, either endorse thereon the amount of principal

Section 17. Survival of Representations and Warranties; Entire Agreement.

All representations and warranties contained herein shall survive the execution and delivery of this Agreement and the Notes, the purchase or transfer by any Purchaser of any Note or portion thereof or interest therein and the payment of any Note, and may be relied upon by any subsequent Holder of a Note, regardless of any investigation made at any time by or on behalf of such Purchaser or any other Holder of a Note.

Section 18. Amendment and Waiver.

Section 18.1. Requirements. This Agreement and the Notes may be amended, and the observance of any term hereof or of the Notes may be waived (either retroactively or prospectively), with (and only with) the written consent of the Obligors and the Required Holders, except that no such amendment or waiver may, without the written consent of the Holder of each Note at the time outstanding affected thereby, (i) subject to the provisions of Section 13 relating to acceleration or rescission, change the amount or time of any prepayment or payment of principal of, or reduce the rate or change the time of payment or method of computation of interest or of the Make-Whole Amount on, the Notes, (ii) change the percentage of the principal amount of the Notes the Holders of which are required to consent to any such amendment or waiver or (iii) amend or waive any part of Section 11.

Section 18.2. Solicitation of Holders of Notes.

(a)Solicitation. The Obligors will provide each Holder of the Notes (irrespective of the amount of Notes then owned by it) with sufficient information, sufficiently far in advance of the date a decision is required, to enable such Holder to make an informed and considered decision with respect to any proposed amendment, waiver or consent in respect of any of the provisions hereof or of the Notes. The Obligors will deliver executed or true and correct copies of each amendment, waiver or consent effected pursuant to the provisions of this Section 18 to each Holder of outstanding Notes promptly following the date on which it is executed and delivered by, or receives the consent or approval of, the requisite Holders of Notes.

(b)Payment. Neither Obligor will directly or indirectly pay or cause to be paid any remuneration, whether by way of supplemental or additional interest, fee or otherwise, or grant any security or provide other credit support, to any Holder of Notes as consideration for or as an inducement to the entering into by any Holder of Notes of any waiver or amendment of any of the terms and provisions hereof unless such remuneration is concurrently paid, or security is concurrently granted or other credit support is concurrently provided, on the same terms, ratably to each Holder of Notes then outstanding even if such Holder did not consent to such waiver or amendment.

(c)Consent in Contemplation of Transfer. Any consent made pursuant to this Section 18 by the Holder of any Note that has transferred or has agreed to transfer such Note to either Obligor, any Subsidiary or any Affiliate of either Obligor and has provided or has agreed to provide such written consent as a condition to such transfer shall be void and of no force or effect except solely as to such Holder, and any amendments effected or waivers granted or to be effected or granted that would not have been or would not be so effected or granted but for such consent (and the consents of all other Holders of Notes that were acquired under the same or similar conditions) shall be void and of no force or effect except solely as to such transferring Holder.

marked to indicate such amendment or waiver. No such amendment or waiver will extend to or affect any obligation, covenant, agreement, Default or Event of Default not expressly amended or waived or impair any right consequent thereon. No course of dealing between either Obligor and the Holder of any Note nor any delay in exercising any rights hereunder or under any Note shall operate as a waiver of any rights of any Holder of such Note. As used herein, the term “this Agreement” and references thereto shall mean this Agreement as it may from time to time be amended or supplemented and includes the Guarantee.

Section 18.4. Notes held by Obligor, Etc.

The Obligors agree and stipulate that, to the extent permitted by applicable law, any such reproduction shall be admissible in evidence as the original itself in any judicial or administrative proceeding (whether or not the original is in existence and whether or not such reproduction was made by such Purchaser in the regular course of business) and any enlargement, facsimile or further reproduction of such reproduction shall likewise be admissible in evidence. This Section 20 shall not prohibit an Obligor or any other Holder of Notes from contesting any such reproduction to the same extent that it could contest the original, or from introducing evidence to demonstrate the inaccuracy of any such reproduction.

Section 21. Confidential Information.

For the purposes of this Section 21, “Confidential Information” means information delivered to such Purchaser by or on behalf of either Obligor or any Subsidiary in connection with the transactions contemplated by or otherwise pursuant to this Agreement that is proprietary in nature and that was clearly marked or labeled or otherwise adequately identified when received by such Purchaser as being confidential information of such Obligor or such Subsidiary, provided that such term does not include information that (a) was publicly known or otherwise known to such Purchaser prior to the time of such disclosure, (b) subsequently becomes publicly known through no act or omission by such Purchaser or any person acting on such Purchaser’s behalf, (c) otherwise becomes known to such Purchaser other than through disclosure by an Obligor or any Subsidiary or (d) constitutes financial statements delivered to such Purchaser under Section 7.1 that are otherwise publicly available. Each Purchaser will maintain the confidentiality of such Confidential Information in accordance with procedures adopted by such Purchaser in good faith to protect confidential information of third parties delivered to such Purchaser, provided that such Purchaser may deliver or disclose Confidential Information to (i) its directors, trustees, officers, employees, agents, attorneys and affiliates (to the extent such disclosure reasonably relates to the administration of the investment represented by its Notes), (ii) its financial advisors and other professional advisors who agree in writing to hold confidential the Confidential Information substantially in accordance with the terms of this Section 21, (iii) any other Holder of any Note, (iv) any Institutional Investor to which it sells or offers to sell such Note or any part thereof or any participation therein (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by the provisions of this Section 21), (v) any Person from which it offers to purchase any security of an Obligor (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by the provisions of this Section 21), (vi) any federal or state regulatory authority having jurisdiction over such Purchaser, (vii) the NAIC or the SVO or, in each case, any similar organization, or any nationally recognized rating agency that requires access to information about such Purchaser’s investment portfolio or (viii) any other Person to which such delivery or disclosure may be necessary or appropriate (w) to effect compliance with any law, rule, regulation or order applicable to such Purchaser, (x) in response to any subpoena or other legal process, (y) in connection with any litigation to which such Purchaser is a party or (z) if an Event of Default has occurred and is continuing, to the extent such Purchaser may reasonably determine such delivery and disclosure to be necessary or appropriate in the enforcement or for

Note Purchase Agreement

Vectren Capital, Corp.

the protection of the rights and remedies under such Purchaser’s Notes or this Agreement. Each Holder of a Note, by its acceptance of a Note, will be deemed to have agreed to be bound by and to be entitled to the benefits of this Section 21 as though it were a party to this Agreement. On reasonable request by an Obligor in connection with the delivery to any Holder of a Note of information required to be delivered to such Holder under this Agreement or requested by such Holder (other than a Holder that is a party to this Agreement or its nominee), such Holder will enter into an agreement with the Obligors embodying the provisions of this Section 21.

Section 22. Substitution of Purchaser.

Each Purchaser shall have the right to substitute any one of its Affiliates as the purchaser of the Notes that it has agreed to purchase hereunder, by written notice to the Company, which notice shall be signed by both such Purchaser and such Affiliate, shall contain such Affiliate’s agreement to be bound by this Agreement and shall contain a confirmation by such Affiliate of the accuracy with respect to it of the representations set forth in Section 6. Upon receipt of such notice, any reference to such Purchaser in this Agreement (other than in this Section 22), shall be deemed to refer to such Affiliate in lieu of such original Purchaser. In the event that such Affiliate is so substituted as a Purchaser hereunder and such Affiliate thereafter transfers to such original Purchaser all of the Notes then held by such Affiliate, upon receipt by the Company of notice of such transfer, any reference to such Affiliate as a “Purchaser” in this Agreement (other than in this Section 22), shall no longer be deemed to refer to such Affiliate, but shall refer to such original Purchaser, and such original Purchaser shall again have all the rights of an original Holder of the Notes under this Agreement.

Section 23. Miscellaneous.

Section 23.1. Successors and Assigns. All covenants and other agreements contained in this Agreement by or on behalf of any of the parties hereto bind and inure to the benefit of their respective successors and assigns (including, without limitation, any subsequent Holder of a Note) whether so expressed or not.

Section 23.2. Payments Due on Non-Business Days. Anything in this Agreement or the Notes to the contrary notwithstanding (but without limiting the requirement in Section 8.2 that the notice of any optional prepayment specify a Business Day as the date fixed for such prepayment), any payment of principal of or Make-Whole Amount or interest on any Note that is due on a date other than a Business Day shall be made on the next succeeding Business Day without including the additional days elapsed in the computation of the interest payable on such next succeeding Business Day; provided that if the maturity date of any Note is a date other than a Business Day, the payment otherwise due on such maturity date shall be made on the next succeeding Business Day and shall include the additional days elapsed in the computation of interest payable on such next succeeding Business Day.

Section 23.3. Accounting Terms. All accounting terms used herein which are not expressly defined in this Agreement have the meanings respectively given to them in accordance with U.S. GAAP.

Note Purchase Agreement

Vectren Capital, Corp.

statements shall be prepared in accordance with U.S. GAAP.

Section 23.4. Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall (to the full extent permitted by law) not invalidate or render unenforceable such provision in any other jurisdiction.

Section 23.5. Construction. Each covenant contained herein shall be construed (absent express provision to the contrary) as being independent of each other covenant contained herein, so that compliance with any one covenant shall not (absent such an express contrary provision) be deemed to excuse compliance with any other covenant. Where any provision herein refers to action to be taken by any Person, or which such Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly by such Person.

For the avoidance of doubt, all Schedules and Exhibits attached to this Agreement shall be deemed to be a part hereof.

Section 23.6. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be an original but all of which together shall constitute one instrument. Each counterpart may consist of a number of copies hereof, each signed by less than all, but together signed by all, of the parties hereto.
