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.

The Purchasers’ obligations hereunder are several and not joint obligations, and no Purchaser 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 June 11, 2015 (the “Execution Date”).

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 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 agents, J.P. Morgan Securities LLC, Mitsubishi UFJ Securities (USA), Inc., U.S. Bancorp Investments, Inc. and Wells Fargo Securities, LLC, have delivered to each Purchaser a copy of a Private Placement Memorandum, dated April 2015 (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,

EXHIBIT 4.2

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, 2014, 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.

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 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.

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).

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.

-7-

EXHIBIT 4.2

(b)    None of the Company, Vectren or any Restricted Subsidiary is (i) in default under any term of any agreement or instrument to which it is a party or by which it is bound, (ii) any order, judgment, decree or ruling of any court, arbitrator or Governmental Authority or (iii) in violation of any applicable law, ordinance, rule or regulation of any Governmental Authority (including without limitation Environmental Laws, the USA PATRIOT Act or any of the other laws and regulations that are referred to in Section 5.16), 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, 2008. The State of Indiana, Vectren’s primary state tax jurisdiction, has conducted examinations of state income tax returns for tax years through December 31, 2008. The statutes of limitations for assessment of federal and Indiana income tax have expired with respect to tax years through 2008.

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;

-8-

EXHIBIT 4.2

(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 (other than for ordinary funding obligations and premiums due and not delinquent) 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 section 430(k) of the Code or to any such penalty or excise tax provisions under the Code or federal law or section 4068 of ERISA or by the granting of a security interest in connection with the amendment of a Plan, 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, 2014, 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.

(c)    Vectren and its ERISA Affiliates have not incurred withdrawal liabilities (and are not subject to contingent withdrawal liabilities) under section 4201 or 4204 of ERISA in respect of Multiemployer Plans that individually or in the aggregate are Material.

(d)    The expected postretirement benefit obligation (determined as of the last day of Vectren’s most recently ended fiscal year in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 715‑60, without regard to liabilities attributable to

-9-

EXHIBIT 4.2

continuation coverage mandated by section 4980B of the Code) of Vectren and its Subsidiaries is not in an amount which could reasonably be expected to result in a Material Adverse Effect.

(e)    The execution and delivery of this Agreement and the issuance and sale of the Notes hereunder will not involve any transaction that is subject to the prohibitions of section 406 of ERISA or in connection with which a tax could be imposed pursuant to section 4975(c)(1)(A)‑(D) of the Code.

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 (a) upon the payment or prepayment of the Notes in accordance with the terms of this Agreement and the Notes or (b) pursuant to a written offer to purchase any outstanding Notes made by any Obligor or an Affiliate pro rata to the holders of all Notes at the time outstanding upon the same terms and conditions. If the holders of more than 33% of the principal amount of the Notes then outstanding accept such offer, the Company shall promptly notify the remaining holders of such fact and the expiration date for the acceptance by holders of Notes of such offer shall be extended by the number of days necessary to give each such remaining holder at least three (3) Business Days from its receipt of such notice to accept such offer. The Company will promptly cancel all Notes acquired by either Obligor or any such Affiliate pursuant to any payment, prepayment or purchase 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:

-22-

EXHIBIT 4.2

“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, with respect to the Called Principal of any Note, 0.50% over the yield to maturity implied by the yield(s) reported as of 10:00 a.m. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as “Page PX1” (or such other display as may replace Page PX1) on Bloomberg Financial Markets for the most recently issued actively traded on‑the‑run U.S. Treasury securities (“Reported”) having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there are no such U.S. Treasury securities Reported having a maturity equal to such Remaining Average Life, then such implied yield to maturity will be determined by (a) converting U.S. Treasury bill quotations to bond equivalent yields in accordance with accepted financial practice and (b) interpolating linearly between the yields Reported for the applicable most recently issued actively traded on‑the‑run U.S. Treasury securities with the maturities (1) closest to and greater than such Remaining Average Life and (2) 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.

If such yields are not Reported or the yields Reported as of such time are not ascertainable (including by way of interpolation), then “Reinvestment Yield” means, with respect to the Called Principal of any Note, 0.50% over the yield to maturity implied by the U.S. Treasury constant maturity yields reported, for the latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (or any comparable successor publication) for the U.S. Treasury constant maturity having a term equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there is no such U.S. Treasury constant maturity having a term equal to such Remaining Average Life, such implied yield to maturity will be determined by interpolating linearly between (1) the U.S. Treasury constant maturity so reported with the term closest to and greater than such Remaining Average Life and (2) the U.S. Treasury constant maturity so

-23-

EXHIBIT 4.2

reported with the term 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.

“Remaining Average Life” means, with respect to any Called Principal, the number of years 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, computed on the basis of a 360‑day year composed of twelve 30‑day months and calculated to two decimal places, 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 8.4 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. If a Change in Control has occurred, such notice shall contain and constitute an offer to prepay Notes as described in subparagraph (c) of this Section 8.7 and shall be accompanied by the certificate described in subparagraph (g) of this Section 8.7.

(b)    Condition to Company Action. The Company will not take any action that consummates or finalizes a Change in Control unless (i) at least 15 Business Days prior to such action it shall have given to each Holder of Notes written notice containing and constituting an offer to prepay Notes as described in subparagraph (c) of this Section 8.7, accompanied by the certificate described

EXHIBIT 4.2

in subparagraph (g) of this Section 8.7, and (ii) contemporaneously with such action, it prepays all Notes required to be prepaid in accordance with this Section 8.7.

(c)    Offer to Prepay Notes. The offer to prepay Notes contemplated by subparagraphs (a) and (b) of this Section 8.7 shall be an offer to prepay, in accordance with and subject to this Section 8.7, all, but not less than all, the Notes held by each holder (in this case only, “holder” in respect of any Note registered in the name of a nominee for a disclosed beneficial owner shall mean such beneficial owner) on a date specified in such offer (the “Proposed Prepayment Date”). If such Proposed Prepayment Date is in connection with an offer contemplated by subparagraph (a) of this Section 8.7, such date shall be not less than 20 days and not more than 30 days after the date of such offer (if the Proposed Prepayment Date shall not be specified in such offer, the Proposed Prepayment Date shall be the 20th day after the date of such offer).

(d)    Acceptance; Rejection. A Holder of Notes may accept or reject the offer to prepay made pursuant to this Section 8.7 by causing a notice of such acceptance or rejection to be delivered to the Company at least 5 Business Days prior to the Proposed Prepayment Date. A failure by a Holder of Notes to respond to an offer to prepay made pursuant to this Section 8.7 shall be deemed to constitute a rejection of such offer by such Holder.

(e)    Prepayment. Prepayment of the Notes to be prepaid pursuant to this Section 8.7 shall be at 100% of the principal amount of such Notes, but without the payment of the Make-Whole Amount, together with interest on such Notes accrued to the date of prepayment. The prepayment shall be made on the Proposed Prepayment Date except as provided in subparagraph (f) of this Section 8.7.

(f)    Deferral Pending Change in Control. The obligation of the Company to prepay Notes pursuant to the offers required by subparagraph (b) and accepted in accordance with subparagraph (d) of this Section 8.7 is subject to the occurrence of the Change in Control in respect of which such offers and acceptances shall have been made. In the event that such Change in Control does not occur on the Proposed Prepayment Date in respect thereof, the prepayment shall be deferred until and shall be made on the date on which such Change in Control occurs. The Company shall keep each Holder of Notes reasonably and timely informed of (i) any such deferral of the date of prepayment, (ii) the date on which such Change in Control and the prepayment are expected to occur, and (iii) any determination by the Company that efforts to effect such Change in Control have ceased or been abandoned (in which case the offers and acceptances made pursuant to this Section 8.7 in respect of such Change in Control shall be deemed rescinded).

(g)    Officer’s Certificate. Each offer to prepay the Notes pursuant to this Section 8.7 shall be accompanied by a certificate, executed by a Senior Financial Officer of the Company and dated

SECTION 9. AFFIRMATIVE COVENANTS.

Section 9.1.    Compliance with Law. Without limiting Section 10.4, 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, Environmental Laws, the USA PATRIOT Act and the other laws and regulations that are referred to in Section 5.16, 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

-26-

EXHIBIT 4.2

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.

-27-

EXHIBIT 4.2

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.

For the purposes of this Section, Vectren or the Company shall be deemed to have satisfied its obligations to prepay Senior Indebtedness to the extent that Vectren or the Company has offered to prepay the Notes or any other Senior Indebtedness with similar prepayment requirements and any Holders have declined such offer of prepayment.

As used in this Section 10.6, a sale, lease or other disposition of assets shall be deemed to be a “substantial part” of the assets of Vectren and its Restricted Subsidiaries if the book value of such assets, when added to the book value of all other assets sold, leased or otherwise disposed of by Vectren and its Restricted Subsidiaries during the period of 12 consecutive months ending on the date of such sale, lease or other disposition, exceeds 25% of the book value of consolidated total assets of Vectren and its Restricted Subsidiaries, determined as of the end of the fiscal quarter immediately preceding such sale, lease or other disposition; provided that there shall be excluded from any determination of a “substantial part” any (i) sale or disposition of assets in the ordinary course of business of Vectren and its Restricted Subsidiaries, (ii) any transfer of assets from Vectren to any Restricted Subsidiary or from any Restricted Subsidiary to Vectren or a Restricted Subsidiary,

EXHIBIT 4.2

and (iii) any sale or transfer of property acquired by Vectren or any Restricted Subsidiary after the date of this Agreement to any Person within 365 days following the acquisition or construction of such property by Vectren or any Restricted Subsidiary if Vectren or a Restricted Subsidiary shall concurrently with such sale or transfer, lease such property, as lessee.

Section 10.7.    Indebtedness. Vectren will not permit, determined as of the end of each of its fiscal quarters, the ratio of Consolidated Indebtedness to Total Capitalization to exceed the Maximum Ratio.

Section 10.8.    Restricted Subsidiary Group.

SECTION 11. GUARANTEE.

Section 11.1.    Guarantee. (a) Vectren irrevocably guarantees, as primary obligor and not merely as surety, (i) the full and punctual payment when due, whether at stated maturity, by acceleration, or otherwise, of all obligations of the Company under this Agreement and the Notes, whether for payment of principal of or interest on the Notes and all other monetary obligations of the Company under this Agreement and the Notes (including any Make‑Whole Amount) and (ii) the full and punctual performance within applicable grace periods of all other obligations of the Company whether for fees, expenses, indemnification or otherwise under this Agreement and the Notes (all the foregoing being hereinafter collectively called the “Guaranteed Obligations”).

(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. The obligations of Vectren hereunder shall not be affected by (i) the failure of any Holder to assert any claim or demand or to enforce any right or remedy against the Company under this Agreement or the Notes or otherwise; (ii) any extension or renewal of any thereof; or (iii) any rescission, waiver, amendment or modification of any of the terms or provisions of this Agreement or the Notes.

(c)    Vectren hereby waives any right to which it may be entitled to have the assets of the Company first be used and depleted as payment of the Company’s obligations hereunder prior to any amounts being claimed from or paid by Vectren hereunder. Vectren hereby waives any right

-35-

EXHIBIT 4.2

to which it may be entitled to require that the Company be sued prior to an action being initiated against Vectren.

(d)    Vectren further agrees that its Guarantee herein constitutes a guarantee of payment when due (and not a guarantee of collection) and waives any right to require that any resort be had by any Holder for payment of the Guaranteed Obligations against the Company.

(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.

-36-

EXHIBIT 4.2

(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 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.

(c)    If any Event of Default described in paragraph (a) or (b) of Section 12 has occurred and is continuing, any Holder or Holders of Notes at the time outstanding affected by such Event of Default may at any time, at its or their option, by notice or notices to the Company, declare all the Notes held by it or them to be immediately due and payable.

Upon any Notes becoming due and payable under this Section 13.1, whether automatically or by declaration, such Notes will forthwith mature and the entire unpaid principal amount of such Notes, plus (x) all accrued and unpaid interest thereon (including, but not limited to, interest accrued thereon at the Default Rate from the date such principal becomes due and payable) and (y) the Make‑Whole Amount determined in respect of such principal amount (to the full extent permitted

-40-

EXHIBIT 4.2

by applicable law), shall all be immediately due and payable, in each and every case without presentment, demand, protest or further notice, all of which are hereby waived. 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 13.3.    Rescission. At any time after any Notes have been declared due and payable pursuant to clause (b) or (c) of Section 13.1, the Required Holders, by written notice to the Company, may rescind and annul any such declaration and its consequences if (a) the Company has paid all overdue interest on the Notes, all principal of and Make‑Whole Amount, if any, on any Notes that are due and payable and are unpaid other than by reason of such declaration, and all interest on such overdue principal and Make‑Whole Amount, if any, and (to the extent permitted by applicable law) any overdue interest in respect of the Notes, at the Default Rate, (b) neither the Company nor Vectren nor any other Person shall have paid any amounts which have become due solely by reason of such declaration, (c) all Events of Default and Defaults, other than non‑payment of amounts that have become due solely by reason of such declaration, have been cured or have been waived pursuant to Section 18, and (d) no judgment or decree has been entered for the payment of any monies due pursuant hereto or to the Notes or to the Guarantee. No rescission and annulment under this Section 13.3 will extend to or affect any subsequent Event of Default or Default or impair any right consequent thereon.

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 such Holder incurred in any enforcement or

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 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.

In the event that as a condition to receiving access to information relating to the Obligors or their Subsidiaries in connection with the transactions contemplated by or otherwise pursuant to this Agreement, any Purchaser or Holder of a Note is required to agree to a confidentiality undertaking (whether through IntraLinks, another secure website, a secure virtual workspace or otherwise) which is different from this Section 21, this Section 21 shall not be amended thereby and, as between such Purchaser or such Holder and the Obligors, this Section 21 shall supersede any such other confidentiality undertaking.

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.

EXHIBIT 4.2

Section 23.1.    Successors and Assigns.

FORM OF OPINION OF INDIANA COUNSEL TO THE COMPANY AND THE GUARANTOR

December ___, 2015

To Each of the Purchasers Listed

on Schedule A to the Note Purchase 

Agreement (as defined below)

Re:    $75,000,000 3.33% Guaranteed Senior Notes, Series A due 2022

$75,000,000 3.90% Guaranteed Senior Notes, Series B due 2030

Ladies and Gentlemen:

We have acted as counsel to VECTREN CAPITAL, CORP., an Indiana corporation (the “Company”), and VECTREN CORPORATION, an Indiana corporation (“Vectren,” and together with the Company, the “Obligors”), in connection with the proposed issuance and sale by the Company, in two series, of $150,000,000 aggregate principal amount of its guaranteed senior notes, of which $75,000,000 aggregate principal amount shall be its 3.33% Guaranteed Senior Notes due 2022 (the “Series A Notes”) and $75,000,000 aggregate principal amount shall be its 3.90% Guaranteed Senior Notes due 2030 (the “Series B Notes,” together with the Series A Notes, the “Notes”) pursuant to the Note Purchase Agreement, dated as of June 11, 2015, by and among each of you and the Obligors (the “Note Purchase Agreement”). All capitalized terms used herein and not specifically defined shall have the meanings ascribed to them in the Note Purchase Agreement. The opinion is being delivered to you pursuant to Section 4.4(a)(i) of the Note Purchase Agreement.

In this connection, we have examined (i) the Note Purchase Agreement, (ii) the Notes, and (iii) such records, certificates and other documents and such questions of law as we have considered necessary and appropriate for the purpose of rendering the opinion set forth below (including, without limitation, certificates of existence issued by the Indiana Secretary of State). As to questions of fact related to such opinions, we have relied solely upon certificates of officers of the Obligors, certificates of public officials (including, without limitation, certificates of existence issued by the Indiana Secretary of State), and the representations and warranties of the Obligors and the Purchasers in the Note Purchase Agreement, and we have made no independent investigation or inquiry with respect to such factual matters.

For purposes of rendering this opinion, we have, with your consent and without investigation, assumed:

(a)the genuineness of the signatures of all persons (other than officers of the Obligors) signing the Note Purchase Agreement, the Notes, and all instruments,

EXHIBIT 4.4(a)(i)

(to Note Purchase Agreement)

EXHIBIT 4.2

documents, certificates, applications, consents, filings and/or agreements related to the transactions contemplated thereby or included in the schedules thereto (collectively, the “Pertinent Documents”);

(b)the authority of the persons executing the Pertinent Documents on behalf of the parties thereto (other than the Obligors);

(c)the authenticity of all documents submitted to us as originals;

(d)the accuracy and completeness of all corporate and public documents and records made available to us;

(e)the conformity to authentic original documents of all documents submitted to us as certified, conformed or photostatic copies;

(f)the due authorization, execution and delivery of the Pertinent Documents by the parties thereto (other than by the Obligors);

(g)your legal existence;

(h)that you have acted in good faith;

(i)your compliance with all laws applicable to you that affect the transactions contemplated by the Note Purchase Agreement; and

(j)that the Pertinent Documents are binding upon all the parties thereto (other than the Obligors) and that all parties thereto (other than the Obligors) will act in accordance with the terms and provisions thereof.

In addition, we have assumed that:

(k)all decisional authorities, statutes, rules and regulations comprising the applicable law for which we are assuming responsibility are published or otherwise generally accessible, in each case in a manner generally available to lawyers practicing in the State of Indiana; and

(l)routine procedural matters, such as service of process or qualification to do business in the jurisdiction, will be satisfied by the party seeking to enforce any of the Pertinent Documents.

Based upon the foregoing and subject to the exceptions hereinafter set forth, we are of the opinion that:

Each Obligor and each of the Restricted Subsidiaries listed in Annex I hereto is duly organized and validly existing under the laws of the State of Indiana. The Company has the corporate power and authority to issue and sell the Notes and to execute, deliver, and perform its obligations under the Note Purchase Agreement and the Notes. Vectren has the corporate power and authority

EXHIBIT 4.4(a)(i)

(to Note Purchase Agreement)

EXHIBIT 4.2

to execute, deliver, and perform its obligations under the Note Purchase Agreement including, without limitation, the Guarantee.

Based solely on our review of certificates issued by the Secretaries of State of each applicable jurisdiction, each Obligor and each Restricted Subsidiary listed in Annex I hereto is duly qualified and (where applicable) is in good standing as a foreign corporation 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.

The Note Purchase Agreement and the Notes have been duly authorized by all necessary corporate action on the part of each Obligor and have been duly executed and delivered by each Obligor.

The execution, delivery, and performance of the Note Purchase Agreement, the Notes and the Guarantee and the consummation of the transactions contemplated thereby do not violate or constitute a default under, (i) any laws, rules, or regulations within the scope of this opinion, (ii) the Articles of Incorporation or By‑Laws of the Company or Vectren, as applicable, or (iii) any Other Agreement that is binding upon either Obligor or any court order known to us that is binding upon any Obligor.

All consents or authorizations of any governmental authority of the United States or the State of Indiana required on the part of either Obligor to issue and sell the Notes and execute, deliver and perform the Note Purchase Agreement have been obtained.

To the best of our knowledge, no litigation, investigation, or proceeding of or before any arbitrator or governmental authority is pending or threatened by or against the Obligors with respect to the validity of the Note Purchase Agreement, the Notes or the Guarantee.

The Note Purchase Agreement constitutes the legal, valid, and binding agreement of the Company and Vectren, enforceable against the Company and Vectren in accordance with its terms, except as the same may be limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium, or similar laws affecting the enforcement of creditors’ rights generally, (ii) general principles of equity (regardless of whether enforceability is considered in proceedings at law or in equity); and (iii) the qualification that the availability of the remedy of specific performance or injunctive relief or of other equitable relief is subject to the discretion of the court before which any proceeding therefor may be brought.

The Notes constitute legal, valid, and binding agreements of the Company, enforceable against the Company in accordance with their respective terms, except as the same may be limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium, or similar laws affecting the enforcement of creditors’ rights generally, (ii) general principles of equity (regardless of whether enforceability is considered in proceedings at law or in equity); and (iii) the qualification that the availability of the remedy of specific performance or injunctive relief or of other equitable relief is subject to the discretion of the court before which any proceeding therefor may be brought.

EXHIBIT 4.4(a)(i)

(to Note Purchase Agreement)

EXHIBIT 4.2

Based upon the representations and warranties of the Obligors set forth in Section 5.13 of the Note Purchase Agreement and your representations set forth in Section 6.1 of the Note Purchase Agreement, it is not necessary in connection with the offering, sale and delivery of the Notes, under the circumstances contemplated by the Note Purchase Agreement to register the Notes or the Guarantee under the Securities Act of 1933, as amended, or to qualify an indenture in respect of the Notes or the Guarantee under the Trust Indenture Act of 1939, as amended.

Neither the execution and delivery by the Company and Vectren of the Note Purchase Agreement and the execution and delivery by the Company of the Notes, nor the execution and delivery by Vectren of the Guarantee, nor the performance by the Obligors of their respective obligations thereunder (including the use of the proceeds from the sale of the Notes in accordance with the Note Purchase Agreement) will violate any provision of Regulations T, U and X of the Board of Governors of the Federal Reserve System.

Neither Obligor is an “investment company” or entity “controlled” by an “investment company” as such terms are defined in the Investment Company of 1940, as amended.

The term “Other Agreement” as used in this opinion letter shall include only those contracts and agreements to which an Obligor is a party or by which any of the Obligors is bound, the breach or default of which would result in a Material Adverse Effect, in each case as determined by officers of the Obligors and identified to us in a Certificate to Counsel and includes but is not limited to the agreements listed in Schedule 5.15(c) of the Note Purchase Agreement.

Our opinion is subject to the following qualifications and limitations:

This opinion letter is limited to the current internal laws of the State of Indiana (without giving effect to any conflict of law principles thereof) and the federal law of the United States of America and we have not considered, and express no opinion on, the laws of any other jurisdiction. Further, we express no opinion as to any federal or state tax laws, or the Employment Retirement Income Security Act of 1974, as amended.

This opinion letter is dated and speaks as of the date hereof. We have no obligation to update or supplement this opinion to reflect any facts or circumstances that may hereafter come to our attention, even though the legal analysis or legal conclusions contained in this opinion letter may be affected by such changes.

Whenever we have stated we assumed any matter, it is intended to indicate that we have assumed such matter without making any factual, legal, or other inquiry or investigation, and without expressing any opinion or stating any conclusion of any kind concerning such matter.

Whenever any statement of this opinion letter is qualified by the phrase “to our knowledge,” “of which we are aware,” or a phrase of similar import, such phrase is intended to mean the actual knowledge of information by the lawyers in our firm who have been principally involved in negotiating the subject transaction, but does not include other information that might be revealed if there were to be undertaken a canvas of all lawyers in our firm, a general search of our files or any type of independent investigation. Moreover, we have not undertaken any independent

EXHIBIT 4.4(a)(i)

(to Note Purchase Agreement)

EXHIBIT 4.2

investigation to determine the accuracy or completeness of such knowledge and any limited inquiries by us should not be regarded as such an investigation.

We were not involved in the preparation or review of offering or other materials prepared for use in the offering of the Notes or otherwise provided to the Purchasers, and, therefore, we express no opinion as to the adequacy or accuracy of any such materials.

We express no opinion with respect to (i) any provisions purporting to waive constitutional or statutory rights, or (ii) any choice of law provisions.

The only opinions intended to be provided herein are those which are expressly stated herein and no opinions by implication are intended or given.

This opinion is furnished solely for your benefit in connection with the transactions contemplated by the Note Purchase Agreement and may not be relied upon by or furnished to any other person, firm, or corporation for any other purpose, without our prior written consent (other than a permitted transferee of any Note or as otherwise required by applicable law or regulation and the opinion may be furnished to the National Association of Insurance Commissioners).

We express no opinion with respect to any future modification, extension or renewal of the Note Purchase Agreement or the Notes.

Very truly yours,

$75,000,000 3.90% Guaranteed Senior Notes, Series B due December 15, 2030

Ladies and Gentlemen:

We have acted as special counsel in the State of Ohio to Vectren Capital, Corp., an Indiana corporation (the “Company”), Vectren Corporation, an Indiana corporation (“Vectren,” and together with the Company, the “Obligors”), and Vectren Energy Delivery of Ohio, Inc., an Ohio corporation (“VEDO”), in connection with the proposed issuance and sale by the Company, in two series, of $150,000,000 aggregate principal amount of its senior notes, of which $75,000,000 aggregate principal amount shall be its 3.33% Guaranteed Senior Notes, Series A due December 15, 2022 (the “Series A Notes”), and $75,000,000 aggregate principal amount shall be its 3.90% Guaranteed Senior Notes, Series B due December 15, 2030 (the “Series B Notes,” and together with the Series A Notes, the “Notes”) pursuant to the Note Purchase Agreement, dated as of June 11, 2015 , by and among each of you, the Obligors, VEDO, Indiana Gas Company, Inc., an Indiana corporation, and Southern Indiana Gas and Electric Company, an Indiana corporation. All capitalized terms used herein and not specifically defined shall have the meanings ascribed to them in the Agreement. This opinion (this “Opinion”) is being delivered to you at the request of the Obligors and VEDO pursuant to Section 4.4(a)(ii) of the Agreement.

In connection with this Opinion, we have examined executed originals or copies of executed originals of the following documents: (1) the Agreement; (2) the Articles of Incorporation and the Code of Regulations of VEDO (collectively, “VEDO’s Constituent Documents”); and (3) resolutions of VEDO authorizing, among other things, the execution, delivery, and performance of the Agreement. We have also examined and, with your permission, relied and based certain portions of our Opinion on, the following:

(a) a certificate of the Secretary of State of the State of Ohio, dated December __, 2015, with respect to VEDO; and

EXHIBIT 4.4(a)(ii)

(to Note Purchase Agreement)

EXHIBIT 4.2

(b) a certificate of Ronald E. Christian, Executive Vice President, Chief Legal and External Affairs Officer, and Secretary of the Company, and Executive Vice President, Chief Legal and External Affairs Officer, and Secretary of VEDO, dated December __, 2015, with respect to certain factual matters relating to VEDO (the “Due Diligence Certificate”).

While we have not independently verified all matters set forth in said certificates, nothing has come to our attention that has caused us to believe that such reliance is not appropriate.

Assumptions

In rendering this Opinion we have, with your permission, assumed (and to our knowledge there are no facts inconsistent with) the following:

(a) that all documents submitted to us as originals are authentic and that all documents submitted to us as certified, conformed, or photostatic copies conform to the authentic original documents;

(b) that all documents and records reviewed by us are accurate and complete and that all statements of fact contained in all documents, records, reports, and certificates submitted to us are true and complete;

(c) that each natural person executing any of the documentation upon which this Opinion has been based is legally competent to do so; and

(d) that the execution, delivery, and performance of the Agreement and all documents upon which this Opinion is based have been duly authorized by all requisite action, corporate, partnership, or otherwise, on behalf of all parties thereto and that the signatures on all such documents are genuine.

Opinion

Based upon the foregoing, and subject to the limitations, qualifications, and exceptions set forth herein, we are of the following Opinion:

EXHIBIT 4.4(a)(ii)

(to Note Purchase Agreement)

EXHIBIT 4.2

1. VEDO is a corporation duly incorporated, validly existing, and in good standing under the laws of the State of Ohio.

2. Based solely on the Due Diligence Certificate, VEDO is qualified to do business and is in good standing as a foreign corporation in each jurisdiction where the character of its properties or the nature of its activities make such qualification necessary or desirable.

Qualifications and Limitations

The opinions expressed above are subject to the following additional qualifications and limitations:

(a) Good Standing. The opinion expressed in paragraph 1, above, with respect to VEDO being in good standing means that a certificate of good standing with respect to each corporation has been issued by the Secretary of State of the State of Ohio. It does not mean that VEDO has received all licenses, registrations, or other governmental or third-party consents needed to commence or to conduct its business or to own its properties.

(b) No Implied Opinion. This Opinion is limited to the matters expressly set forth herein; and no opinion is to be implied or may be inferred beyond the matters expressly so stated herein.

(c) Ohio Law. We express no opinion with respect to the effect of any laws other than the laws of the State of Ohio and laws of the United States of general application to transactions in the State of Ohio.

(d) No Guaranty. This Opinion constitutes our professional opinion as to certain legal consequences of, and the applicability of certain laws to, the facts, circumstances and documents described herein. It is not a guaranty, however, and may not be construed as such.

(e) Captions. The captions in this Opinion are for convenience of reference only and shall not limit, amplify, or otherwise modify the provisions hereof.

(f) Subsequent Events. This Opinion is given as of the date set forth above, and we assume no, and hereby disclaim any, obligation to update or to supplement this

EXHIBIT 4.4(a)(ii)

(to Note Purchase Agreement)

EXHIBIT 4.2

Opinion to reflect any facts or circumstances that may hereafter come to our attention, or any changes in any laws, ordinances, rules, or regulations that may hereafter occur, that might affect the opinions expressed herein.

(g) Restrictions on Use. This Opinion is given solely for the benefit of the parties to whom this Opinion is addressed, and the undersigned has no responsibility to any other person or entity. This Opinion may not, without our prior written consent, be relied upon by any person or entity other than the parties to whom this Opinion is addressed and permitted transferees of the Notes. Copies of this Opinion may be furnished, in addition to the parties to whom this Opinion is addressed and permitted transferees of the Notes, as otherwise required by applicable law or regulation and to the National Association of Insurance Commissioners.
