Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument.

Section 104. Acts of Holders; Record Dates.

Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments or record or both are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments and any such record (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments and so voting at any such meeting. Proof of execution of any such instrument or of a writing appointing any such agent, or of the holding by any Person of a Security, shall be sufficient for any purpose of this Indenture and (subject to Section 601) conclusive in favor of the Trustee and the Company if made in the manner provided in this Section. The record of any meeting of Holders of Securities shall be proved in the manner provided in Section 1306.

Notwithstanding the foregoing, with respect to any Global Security, nothing herein shall prevent the Company, the Trustee, or any agent of the Company or the Trustee, from giving effect to any request, demand, authorization, direction, notice, consent, waiver or other action provided in this Indenture to be given or taken by a Depositary or impair, as between a Depositary and such holders of beneficial interests, the operation of customary practices governing the exercise of the rights of the Depositary (or its nominee) as Holder of any Security.

Without limiting the generality of this Section 104, unless otherwise provided in or pursuant to this Indenture, a Holder, including a Depositary that is a Holder of a Global Security, may make, give or take, by a proxy or proxies duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other action provided in or pursuant to this Indenture to be made, given or taken by Holders, and a Depositary that is a Holder of a Global Security may give its proxy or proxies to the Depositary’s participants or the beneficial owners of interests in any such Global Security, as the case may be, through such Depositary’s standing instructions and customary practices.

Subject to the next succeeding paragraph, the Company may, in the circumstances permitted by the Trust Indenture Act, fix any day as the record date for the purpose of determining the Holders of Securities of any series entitled to give or take any request, demand, authorization, direction, notice, consent, waiver or other action, or to vote on any action, authorized or permitted to be given or taken by Holders of Securities of such series. If not set by the Company prior to the first solicitation of a Holder of Securities of such series made by any Person in respect of any such action, or in the case of any such vote, prior to such vote, the record date for any such action or vote shall be the 30th day prior to such first solicitation or vote, or, if later, the date of the most recent list of Holders required to be provided pursuant to Section 701, as the case may be. With regard to any record date for action to be taken by the Holders of one or more series of Securities, only the Holders of Securities of such series on such date (or their duly designated proxies) shall be entitled to give or take, or vote on, the relevant action.

The Trustee shall fix a record date for the purpose of determining the Persons who are beneficial owners of interests in any permanent Global Security held by a Depositary and who are entitled under the procedures of such Depositary to make, give or take, by a proxy or proxies duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other action provided in or pursuant to this Indenture to be made, given or taken by Holders. If such a record date is fixed, the Holders on such record date or their duly appointed proxy or proxies, and only such Persons, shall be entitled to make, give or take such request, demand, authorization, direction, notice, consent, waiver or other action, whether or not such Holders remain Holders after such record date. No such request, demand, authorization, direction, notice, consent, waiver or other action shall be valid or effective if made, given or taken more than 90 days after such record date.

7

(c) The principal amount and serial numbers of Securities held by any Person, and the date of holding the same, shall be proved by the Security Register.

(d) The fact and date of execution of any such instrument or writing, the authority of the Person executing the same and the date of holding the same may also be proved in any other reasonable manner which the Trustee deems sufficient; and the Trustee may in any instance require further proof with respect to any of the matters referred to in this Section.

(e) Any request, demand, authorization, direction, notice, consent, election, waiver or other Act of the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Security.

Section 105. Notices, etc., to Trustee and the Company. Any request, demand, authorization, direction, notice, consent, election, waiver or other Act of Holders of a series of Securities or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with,

(1) the Trustee of such series by any Holder of a Security of such series or by the Company shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with the Trustee of such series at its Corporate Trust Office, or

(2) the Company by the Trustee of such series or by any Holder of a Security of such series shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to the Company, addressed to the attention of its Corporate Secretary, at 801 East 86th Avenue, Merrillville, Indiana 46410, or at any other address previously furnished in writing to the Trustee of such series by the Company.

The Trustee shall have the right to accept and act upon instructions, including funds transfer instructions (“Instructions”), pursuant to this Indenture and related documents sent by Electronic Means; provided, however, that the Company shall provide to the Trustee an incumbency certificate listing officers with the authority to provide such Instructions (“Authorized Officers”) or directions and containing specimen signatures of such Authorized Officers, which such incumbency certificate shall be amended and replaced whenever a person is to be added or deleted from the listing. If the Company elects to give the Trustee Instructions using Electronic Means and the Trustee in its discretion elects to act upon such Instructions, the Trustee’s understanding of such Instructions shall be deemed controlling. The Company understands and agrees that the Trustee cannot determine the identity of the actual sender of such Instructions and that the Trustee shall conclusively presume that directions that purport to have been sent by an Authorized Officer listed on the incumbency certificate provided to the Trustee have been sent by such Authorized Officer. The Company shall be responsible for ensuring that only Authorized Officers transmit such Instructions to the Trustee and that the Company and all Authorized Officers are solely responsible to safeguard the use and confidentiality of applicable user and authorization codes, passwords and/or authentication keys upon receipt by the Company. The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from its reliance upon and compliance with such instructions notwithstanding such instructions conflict or are inconsistent with a subsequent written instruction. The Company agrees (i) to assume all risks arising out of its use of Electronic Means to submit Instructions to the Trustee, including the risk of the Trustee acting on unauthorized Instructions, and the risk of interception and misuse by third parties; (ii) that it is fully informed of the protections and risks associated with the various methods of transmitting Instructions to the Trustee and that there may be more secure methods of transmitting Instructions than the method(s) selected by the Company; (iii) that the security procedures (if any) to be followed in connection with its transmission of Instructions provide to it a commercially reasonable degree of protection in light of its particular needs and circumstances; and (iv) to notify the Trustee immediately upon learning of any compromise or unauthorized use of the security procedures. “Electronic Means” shall mean the following communications methods: e-mail, secure electronic transmission containing applicable authorization codes, passwords and/or authentication keys issued by the Trustee, or another method or system specified by the Trustee as available for use in connection with its services hereunder.

8

Notwithstanding any other provision of this Indenture or any Security, where this Indenture or any Security provides for notice of any event or any other communication (including any notice of redemption or repurchase) to a Holder of a Global Security (whether by mail or otherwise), such notice shall be sufficiently given if given to the Depositary (or its designee) pursuant to the standing instructions from the Depositary or its designee, including by electronic mail in accordance with accepted practices at the Depositary.

Section 106. Notice to Holders of Securities; Waiver. Except as otherwise expressly provided herein, where this Indenture provides for notice to Holders of Securities (of any series) of any event, such notice shall be sufficiently given if in writing and mailed, first-class postage prepaid, to each Holder of a Security of such series affected by such event, at his address as it appears in the Security Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such Notice.

In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder. In any case where notice to Holders of Securities is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder of a Security shall affect the sufficiency of such notice with respect to other Holders of Securities given as provided above.

Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders of Securities shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

Section 107. Language of Notices, Etc. Any request, demand, authorization, direction, notice, consent, election or waiver required or permitted under this Indenture shall be in the English language, except that any published notice may be in an official language of the country of publication.

Section 108. Conflict with Trust Indenture Act. If any provision hereof limits, qualifies or conflicts with any duties under any required provision of the Trust Indenture Act deemed included herein by Section 318(c) thereof, such required provision shall control.

Section 109. Effect of Headings and Table of Contents. The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

Section 110. Successors and Assigns. All covenants and agreements in this Indenture by the Company shall bind their respective successors and assigns, whether so expressed or not.

Section 111. Separability Clause. In case any provision in this Indenture or the Securities shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

Section 112. Benefits of Indenture. Nothing in this Indenture or the Securities, express or implied, shall give to any Person, other than the parties hereto, their successors hereunder and the Holders of Securities (and, with respect to the provisions of Article Fifteen, the holders of Senior Indebtedness), any benefit or any legal or equitable right, remedy or claim under this Indenture.

Section 113. Governing Law. This Indenture and the Securities shall be governed by and construed in accordance with the internal law of the State of New York, without giving effect to any contrary conflict of laws or choice of law provisions of the law of the State of New York or any other jurisdiction.

9

Section 114. Legal Holidays. In any case where any Interest Payment Date, Redemption Date or Stated Maturity of any Security shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or of the Securities) payment of interest or principal (and premium, if any) need not be made at such Place of Payment on such date, but may be made on the next succeeding Business Day at such Place of Payment with the same force and effect as if made on the Interest Payment Date or Redemption Date, or at the Stated Maturity; provided, that no interest shall accrue on the amount so payable for the period from and after such Interest Payment Date, Redemption Date or Stated Maturity, as the case may be.

If the forms of Securities of any series are established by action taken pursuant to a Board Resolution, a copy of an appropriate record of such action shall be certified by the Corporate Secretary or an Assistant Corporate Secretary of the Company and delivered to the Trustee at or prior to the delivery of the Order of the Company contemplated by Section 303 for the authentication and delivery of such Securities.

The Trustee’s certificates of authentication shall be in substantially the form set forth in this Article or Article Six.

If Securities of a series are issuable in global form, any such Security may provide that it or any number of such Securities shall represent the aggregate amount of all Outstanding Securities of such series (or such lesser amount as is permitted by the terms thereof) from time to time endorsed thereon and may also provide that the aggregate amount of Outstanding Securities represented thereby may from time to time be increased or reduced to reflect exchanges. Any endorsement of any Security in global form to reflect the amount, or any increase or decrease in the amount, or changes in the rights of Holders, of Outstanding Securities represented thereby shall be made in such manner and by such Person or Persons as shall be specified therein or in the Order of the Company to be delivered pursuant to Sections 303 or 304 with respect thereto.

Such Board Resolution may provide general terms or parameters for Securities of such series and may provide that the specific terms of particular Securities of such series, and the Persons authorized to determine such terms or parameters, may be determined in accordance with or pursuant to the Order of the Company referred to in the third paragraph of Section 303.

Section 302. Denominations. Unless otherwise provided as contemplated by Section 301 with respect to any series of Securities, the Securities of each series shall be issuable in denominations of $2,000 or any integral multiple thereof.

Section 303. Execution, Authentication, Delivery and Dating. The Securities shall be executed on behalf of the Company by its Chairman of the Board, its Vice Chairman, its President or one of its Vice Presidents. The signature of any of these officers on the Securities may be manual, electronic or facsimile.

Securities bearing the manual, electronic or facsimile signatures of individuals who were at any time relevant to the authorization thereof the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities.

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series executed on behalf of the Company to the Trustee for authentication by the Trustee together with an Order of the Company for the authentication and delivery of such Securities, and the Trustee in accordance with such Order shall authenticate and deliver such Securities; provided, that, with respect to Securities of a series constituting a medium term note program, the Trustee shall authenticate and deliver Securities of such series for original issue from time to time in the aggregate principal amount established for such series pursuant to such procedures acceptable to the Trustee and to such recipients as may be specified from time to time by an Order of the Company. The maturity dates, original issue dates, interest rates and any other terms of the Securities of a subseries of any medium term note program shall be determined by or pursuant to such Order of the Company and procedures.

In authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and (subject to Sections 315(a) through 315(d) of the Trust Indenture Act) shall be fully protected in relying upon:

(a) the Board Resolution or indenture supplemental hereto establishing the form of the Securities of that series pursuant to Section 201 and the terms of the Securities of that series pursuant to Section 301 (or, in the case of a Board Resolution, pursuant to which such form and terms are established);

(b) an Officers’ Certificate pursuant to Sections 201 and 301 stating that no Event of Default under this Indenture has occurred and is continuing and complying with Section 102; and

14

(c) an Opinion of Counsel complying with Section 102 stating,

(i) that the forms of such Securities have been established by or pursuant to a Board Resolution or by an indenture supplemental hereto, as permitted by Section 201 and in conformity with the provisions of this Indenture;

(ii) that the terms of such Securities have been established by or pursuant to a Board Resolution or by an indenture supplemental hereto, as permitted by Sections 201 and 301 and in conformity with the provisions of this Indenture;

(iii) that such Securities, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any customary conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company entitled to the benefits provided by the Indenture, enforceable in accordance with their respective terms, except to the extent that the enforcement of such obligations may be subject to bankruptcy laws or insolvency laws or other similar laws, general principles of equity and such other qualifications as such counsel shall conclude are customary or do not materially affect the rights of the Holders of such Securities; and

(iv) such other matters as the Trustee may reasonably request.

With respect to Securities of a subseries of a medium term note program, the Trustee may conclusively rely on the documents and opinion delivered pursuant to Sections 201 and 301 and this Section 303, as applicable (unless revoked by superseding comparable documents or opinions), with respect to the establishment of the medium term note program as to the authorization of the Board of Directors of the Company of any Securities delivered hereunder, the form thereof and the legality, validity, binding effect and enforceability thereof.

Notwithstanding the provisions of Section 301 and of the preceding two paragraphs, if not all the Securities of any series are to be issued at one time, it shall not be necessary to deliver the Officers’ Certificate otherwise required pursuant to Section 301 or the documents otherwise required pursuant to the preceding clauses (a), (b) or (c) prior to or at the time of issuance of each Security, but such documents shall be delivered prior to or at the time of issuance of the first Security of such series and shall pertain to all of the Securities of such series. After any such first delivery, any separate Request by the Company that the Trustee authenticate Securities of such series for original issue will be deemed to be a certification by the Company that all conditions precedent provided for in this Indenture relating to authentication and delivery of such Securities continue to have been complied with.

If such forms or terms have been so established by or pursuant to a Board Resolution or by an indenture supplemental hereto as permitted by Sections 201 and 301, the Trustee shall have the right to decline to authenticate and deliver any Securities of such series:

(i) if the Trustee, being advised by counsel, determines that such action may not lawfully be taken;

(ii) if the Trustee in good faith by its board of directors, executive committee or a committee of directors or Responsible Officers of the Trustee in good faith determines that such action would expose the Trustee to personal liability to Holders of any Outstanding series of Securities; or

(iii) if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties and immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee.

If the Company shall establish pursuant to Section 301 that the Securities of a series are to be issued in whole or in part in the form of one or more Global Securities, then the Company shall execute and the Trustee shall, in accordance with this Section and the Order of the Company with respect to such series, authenticate and deliver one or more Global Securities in permanent form that (i) shall represent and shall be denominated in an amount equal to the aggregate principal amount of the Outstanding Securities of such series to be represented by such Global Security or Securities, (ii) shall be registered in the name of the Depositary for such Global Security or Securities or the nominee of such Depositary, (iii) shall be delivered by the Trustee to such Depositary or pursuant to such Depositary’s instruction and (iv) shall bear a legend as required by Section 204.

15

Each Security shall be dated the date of its authentication. Each Global Security shall be dated as of the date specified as contemplated by Section 301.

No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual or electronic signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture.

Section 304. Temporary Securities. Pending the preparation of definitive Securities of any series, the Company may execute, and upon an Order of the Company the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued, in registered form and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities (but which do not affect the rights or duties of the Trustee).

Except in the case of temporary Securities in global form, which shall be exchanged in accordance with the provisions thereof, if temporary Securities of any series are issued, the Company will cause definitive Securities of that series to be prepared without unreasonable delay. After the preparation of definitive Securities of such series, the temporary Securities of such series shall be exchangeable for definitive Securities of such series upon surrender of the temporary Securities of such series at the office or agency of the Company in a Place of Payment for that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Securities of the same series of authorized denominations and of like tenor. Until so exchanged, the temporary Securities of any series, including temporary Securities in global form, shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series.

Section 305. Registration, Registration of Transfer and Exchange. The Company shall cause to be kept at one of its offices or agencies designated pursuant to Section 1002 a register (referred to as the “Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities of each series and of transfers and exchanges of Securities of such series. Said office or agency is hereby appointed the security registrar (referred to as the “Security Registrar”) for the purpose of registering Securities of each series and transfers and exchanges of Securities of such series as herein provided.

Upon surrender for registration of transfer of any Security of any series at the office or agency in a Place of Payment maintained for such purpose for such series, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of the same series, Stated Maturity and original issue date, of any authorized denominations and of like tenor and aggregate principal amount.

At the option of the Holder, Securities of any series (except a Global Security representing all or a portion of such series) may be exchanged for Securities of the same series, Stated Maturity and original issue date, of any authorized denominations and of like tenor and aggregate principal amount, upon surrender of the Securities to be exchanged at any such office or agency.

Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive.

16

All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange.

Every Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed, by the Holder thereof or his attorney duly authorized in writing.

No service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 304, 906 or 1107 not involving any transfer.

The Company shall not be required (i) to issue, to register the transfer of or to exchange Securities of any series during a period of 15 Business Days immediately preceding the date notice is given identifying the serial numbers of the Securities of that series called for redemption, or (ii) to issue, to register the transfer of or to exchange any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part.

Notwithstanding the foregoing, except as otherwise specified as contemplated by Section 301, any Global Security shall be exchangeable pursuant to this Section 305 or Sections 304, 306, 906 or 1107 for Securities registered in the name of, and a transfer of a Global Security of any series may be registered to, any Person other than the Depositary for such Global Security or its nominee only if:

(i) such Depositary notifies the Company that it is unwilling or unable to continue as Depositary for such Global Security or if at any time such Depositary ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended, and a successor Depositary is not appointed by the Company within 90 days;

(ii) the Company executes and delivers to the Trustee an Order of the Company that such Global Security shall be so exchangeable and the transfer thereof so registrable; or

(iii) there shall have occurred and be continuing an Event of Default or an event which, with the giving of notice or lapse of time, would constitute an Event of Default with respect to the Securities of such series.

Upon the occurrence in respect of any Global Security of any series of any one or more of the conditions specified in clauses (i), (ii) or (iii) of the preceding sentence or such other conditions as may be specified as contemplated by Section 301 for such series, then without unnecessary delay, but in any event not later than the earliest date on which such interests may be so exchanged, the Company shall deliver to the Trustee definitive Securities of that series in aggregate principal amount equal to the principal amount of such Global Security, executed by the Company.

On or after the earliest date on which such interests may be so exchanged, such Global Securities shall be surrendered from time to time by the Depositary and in accordance with instructions given to the Trustee and the Depositary (which instructions shall be in writing but need not be contained in or accompanied by an Officers’ Certificate or be accompanied by an Opinion of Counsel), as shall be specified in the Order of the Company with respect thereto to the Trustee, as the Company’s agent for such purpose, to be exchanged, in whole or in part, for definitive Securities of the same series without service charge. The Trustee shall authenticate and make available for delivery, in exchange for each portion of such surrendered Global Security, a like aggregate principal amount of definitive Securities of the same series of authorized denominations and of like tenor as the portion of such Global Security to be exchanged; provided, that no such exchanges may occur during a period beginning at the opening of business 15 Business Days before any selection of Securities of that series to be redeemed and ending on the relevant Redemption Date.

17

Promptly following any such exchange in part, such Global Security shall be returned by the Trustee to the Depositary in accordance with the instructions of the Company referred to above. If a Security is issued in exchange for any portion of a Global Security after the close of business at the office or agency where such exchange occurs on (i) any Regular Record Date for such Security and before the opening of business at such office or agency on the next Interest Payment Date, or (ii) any Special Record Date for such Security and before the opening of business at such office or agency on the related proposed date for payment of interest or Defaulted Interest, as the case may be, interest shall not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such Security, but shall be payable on such Interest Payment Date or proposed date for payment, as the case may be, only to the Person to whom interest in respect of such portion of such Global Security is payable in accordance with the provisions of this Indenture.

Section 306. Mutilated, Destroyed, Lost and Stolen Securities. If any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series, Stated Maturity and original issue date, and of like tenor and principal amount and bearing a number not contemporaneously outstanding.

If there shall be delivered to the Company and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and upon its Request the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same series, Stated Maturity and original issue date, and of like tenor and principal amount and bearing a number not contemporaneously outstanding.

In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security.

Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

Every new Security of any series issued pursuant to this Section in lieu of any mutilated, destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the mutilated, destroyed, lost or stolen Security shall be at any time enforceable by anyone, and any such new Security shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder.

The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities.

Section 307. Payment of Interest; Interest Rights Preserved. Unless otherwise provided as contemplated by Section 301 with respect to any series of Securities, interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest.

Any interest on any Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (1) or (2) below:

18

(1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as provided in this clause.

Following the Trustee’s receipt of such notice, the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder of Securities of such series at the address of such Holder as it appears in the Security Register, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2).

(2) The Company may make payment of any Defaulted Interest on the Securities of any series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

Subject to the foregoing provisions of this Section, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.

Section 308. Persons Deemed Owners. Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may deem and treat the Person in whose name such Security is registered as the absolute owner of such Security for the purpose of receiving payment of principal of (and premium, if any) and (subject to Section 307) interest on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by any notice to the contrary.

No holder of any beneficial interest in any Global Security held on its behalf by a Depositary (or its nominee) shall have any rights under this Indenture with respect to such Global Security or any Security represented thereby, and such Depositary may be treated by the Company, the Trustee, and any agent of the Company or the Trustee as the owner of such Global Security or any Security represented thereby for all purposes whatsoever. None of the Company, the Trustee, any Paying Agent or the Security Registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

Section 309. Cancellation. All Securities surrendered for payment, redemption, registration of transfer or exchange or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly canceled by the Trustee. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be promptly canceled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities canceled as provided in this Section, except as expressly permitted by this Indenture. All canceled Securities held by the Trustee shall be destroyed and certification of their destruction delivered to the Company, unless an Order of the Company shall direct that canceled Securities be returned to the Company.

19

The repayment of any principal amount of Securities pursuant to such option of the Holder to require repayment of Securities before their Stated Maturity, for purposes of this Section 309, shall not operate as a payment, redemption or satisfaction of the indebtedness represented by such Securities unless and until the Company, at its option, shall deliver or surrender the same to the Trustee with an Order that such Securities be canceled.

Section 310. Computation of Interest. Except as otherwise specified as contemplated by Section 301(4) for Securities of any series, interest on the Securities of each series shall be computed on the basis of a 360-day year consisting of twelve 30-day months.

Section 311. CUSIP, ISIN and Common Code Numbers. The Company in issuing the Securities may use “CUSIP”, “ISIN” or “Common Code” numbers (if then generally in use) and, if so, the Trustee shall use “CUSIP”, “ISIN” or “Common Code” numbers in notices of redemption as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers.

Article Four

Satisfaction and Discharge

Section 401. Satisfaction and Discharge of Indenture. This Indenture shall upon a Request of the Company cease to be of further effect (except as to any surviving rights of registration of transfer or exchange or conversion of Securities herein expressly provided for, and any right to receive additional amounts, as provided in Section 1004), and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when:

(1) either

(A) all Securities theretofore authenticated and delivered (other than (i) Securities which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 306, and (ii) Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company, or discharged from such trust, as provided in Section 1003) have been delivered to the Trustee for cancellation; or

(B) all such Securities not theretofore delivered to the Trustee for cancellation

(i) have become due and payable, or

(ii) will become due and payable at their Stated Maturity within one year, or

(iii) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company,

and the Company, in the case of (B)(i), (ii) or (iii) above, has deposited or caused to be deposited with the Trustee as trust funds in trust dedicated solely for such purpose an amount sufficient, without reinvestment, to pay and discharge the entire indebtedness on such Securities not theretofore delivered to the Trustee for cancellation, for principal (and premium, if any) and interest to the date of such deposit (in the case of Securities which have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be;

20

(2) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and

(3) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with.

In the event there are Securities of two or more series hereunder, the Trustee shall be required to execute an instrument acknowledging satisfaction and discharge of this Indenture only if requested to do so with respect to Securities of all series as to which it is Trustee and if the other conditions thereto are met. In the event there are two or more Trustees hereunder, then the effectiveness of any such instrument shall be conditioned upon receipt of such instruments from all Trustees hereunder.

Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 607, the obligations of the Trustee to any Authenticating Agent under Section 614 and, if money shall have been deposited with the Trustee pursuant to subclause (B) of clause (1) of this Section, the obligations of the Trustee under Sections 305, 306, 402, 1002 and 1003 shall survive.

Section 402. Application of Trust Money. Subject to the provision of the last paragraph of Section 1003, all money deposited with the Trustee pursuant to Section 401 shall be held in trust and applied by it, in accordance with the provisions of the Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee, but such money need not be segregated from other funds, except to the extent required by law.

Article Five

Remedies

Section 501. Events of Default. “Event of Default,” wherever used herein with respect to Securities of any series, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

(1) the Company defaults in the payment of any interest (including any additional amounts due under Section 1004 as specified therein) upon any Security of that series when it becomes due and payable and continuance of such default for a period of 60 days; or

(2) the Company defaults in the payment of the principal (including any additional amounts due under Section 1004 as specified therein) of (or premium, if any, on) any Security of that series at its Maturity and continuance of such default for a period of three Business Days thereafter; or

(4) the Company defaults in the performance of or breaches any covenant or warranty of the Company in this Indenture (other than a covenant or warranty a default in whose performance or whose breach is elsewhere in this Section specifically dealt with or which has expressly been included in or pursuant to this Indenture solely for the benefit of one or more series of Securities other than that series), and continuance of such default or breach for a period of 90 days after there has been given, by registered or certified mail, to the Company by the Trustee, or to the Company and the Trustee by the Holders of at least 33% in principal amount of the Outstanding Securities of that series, a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder; or

21

(5) a default under any bond, debenture, note or other evidence of indebtedness for money borrowed by the Company (including a default with respect to Securities of any series other than that series) or under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any indebtedness for money borrowed by the Company (including this Indenture), whether such indebtedness now exists or shall hereafter be created, which default shall constitute a failure to pay in excess of $50,000,000 of the principal or interest of such indebtedness when due and payable after the expiration of any applicable grace period with respect thereto or shall have resulted in such indebtedness in an amount in excess of $50,000,000 becoming or being declared due and payable prior to the date on which it would otherwise have become due and payable, without such indebtedness having been discharged or such acceleration having been rescinded or annulled within a period of 60 days after there shall have been given, by registered or certified mail, to the company by the Trustee or to the Company and the Trustee by the Holders of at least 33% in principal amount of the Outstanding Securities of that series a written notice specifying such default and requiring the Company to cause such indebtedness to be discharged or cause such acceleration to be rescinded or annulled and stating that such notice is a “Notice of Default” hereunder; provided, that subject to the provisions of Sections 601 and 602, the Trustee shall not be deemed to have knowledge of such default unless the Trustee shall have received written notice thereof from the Company, from any Holder, from the holder of any such indebtedness or from the trustee under any such mortgage, Indenture or other instrument; or

(6) the entry by a court having jurisdiction in the premises of (A) a decree or order for relief in respect of the Company in an involuntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or (B) a decree or order adjudging the Company a bankrupt or insolvent, or approving as properly filed a petition by one or more Persons other than the Company or any of its Affiliates seeking reorganization, arrangement, adjustment or composition of or in respect of the Company under any applicable Federal or State law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official for the Company or for any substantial part of its property, or ordering the liquidation or winding up of the affairs of the Company, and the continuance of any such decree or order for relief or any such other decree or order unstayed and in effect for a period of 90 consecutive days; or

(8) any other Event of Default provided with respect to Securities of that series.

Section 502. Acceleration of Maturity; Rescission and Annulment. If an Event of Default with respect to Securities of any series at the time Outstanding occurs and is continuing, then in every such case the Trustee or the Holders of not less than 33% in principal amount of the Outstanding Securities of that series may declare the principal amount (or, if the Securities of that series are Original Issue Discount Securities, such portion of the principal amount as may be specified in the terms of that series) of all of the Securities of that series to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such principal amount (or specified amount) shall become immediately due and payable.

At any time after such a declaration of acceleration with respect to Securities of any series has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the Outstanding Securities of that series, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if:

22

(1) the Company has paid or deposited with the Trustee a sum sufficient to pay:

(A) all overdue interest on all Securities of that series;

(B) the principal of (and premium, if any, on) any Securities of that series which have become due otherwise than by such declaration of acceleration and interest thereon at the rate or rates prescribed therefor in such Securities;

(C) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate or rates prescribed therefor in such Securities; and

(D) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due to the Trustee under Section 607;

and

(2) all Events of Default with respect to Securities of that series, other than the non-payment of the principal of Securities of that series which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 513.

No such rescission and annulment shall affect any subsequent default or impair any right consequent thereon.

Section 503. Collection of Indebtedness and Suits for Enforcement by Trustee. The Company covenants that if:

(1) default is made in the payment of any interest on any Security when such interest becomes due and payable and such default continues for a period of 30 days, or

(2) default is made in the payment of the principal of (or premium, if any, on) any Security at the Maturity thereof and such default continues for a period of three Business Days, the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and payable on such Securities for principal (and premium, if any) and interest, with interest on any overdue principal (and premium, if any) and on any overdue interest, to the extent that payment of such interest shall be legally enforceable, at the rate or rates prescribed therefor in such Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due to the Trustee under Section 607.

If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree, and may enforce the same against the Company or any other obligor upon such Securities and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon such Securities, wherever situated.

If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture, or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

Section 504. Trustee May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Securities or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company or any other obligor for the payment of overdue principal or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise:

23

(i) to file and prove a claim for the whole amount of principal (and premium, if any) and interest owing and unpaid in respect of the Securities and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due to the Trustee under Section 607) and of the Holders of Securities allowed in such judicial proceeding; and

(ii) to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder of Securities to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders of Securities, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 607.

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder of a Security any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder of a Security in any such proceeding.

Section 505. Trustee May Enforce Claims Without Possession of Securities. All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered.

Section 506. Application of Money Collected. Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal (or premium, if any) or interest, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

FIRST: To the payment of all amounts due the Trustee, including in its other capacities provided for herein, under Section 607; and

SECOND: To the payment of all Senior Indebtedness of the Company if and to the extent required by Article Fifteen; and

THIRD: To the payment of the amounts then due and unpaid for principal of (and premium, if any) and interest on the Securities in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal (and premium, if any) and interest; and

FOURTH: To the Company.

Section 507. Limitation on Suits. No Holder of any Security of any series shall have any right to institute any proceeding, judicial or otherwise with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless:

(1) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of that series;

24

(2) the Holders of not less than a majority in principal amount of the Outstanding Securities of that series shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder;

(3) such Holder or Holders have offered to the Trustee such reasonable indemnity as it may require against the costs, expenses and liabilities to be incurred in compliance with such request;

(4) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding;

and

(5) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities of that series;

it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under this Indenture except in the manner herein provided and for the equal and ratable benefit of all of such Holders.

Section 508. Unconditional Right of Holders to Receive Principal, Premium and Interest. Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment of the principal of (and premium, if any) and (subject to Section 307) interest on such Security on the Stated Maturity or Maturities expressed in such Security (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder.

Section 509. Restoration of Rights and Remedies. If the Trustee or any Holder of a Security has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders of Securities shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

Section 510. Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders of Securities is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise shall, not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 511. Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Security to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders of Securities may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders of Securities, as the case may be.

Section 512. Control by Holders of Securities. The Holders of a majority in principal amount of the Outstanding Securities of any series shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Securities of such series; provided, that:

25

(1) such direction shall not be in conflict with any rule of law or with this Indenture, expose the Trustee to personal liability or be unduly prejudicial to Holders not joined therein; and

(2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

Section 513. Waiver of Past Defaults. The Holders of not less than a majority in principal amount of the Outstanding Securities of any series may on behalf of the Holders of all the Securities of such series waive any past default hereunder with respect to such series and its consequences, except a default:

(1) in the payment of the principal of (or premium, if any) or interest on any Security of such series; or

(2) in respect of a covenant or provision hereof which under Article Nine cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series affected.

Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon.

Section 514. Undertaking for Costs. All parties to this Indenture agree, and each Holder of any Security by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Outstanding Securities of any series, or to any suit instituted by any Holder of any Security for the enforcement of the payment of the principal of (or premium, if any) or interest on any Security on or after the Stated Maturity or Maturities expressed in such Security (or, in the case of redemption, on or after the Redemption Date).

Section 515. Waiver of Stay or Extension Laws. The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

Article Six

The Trustee

Section 601. Certain Duties and Responsibilities.

(a) Except during the continuance of an Event of Default with respect to Securities of any series:

(1) the Trustee undertakes to perform, with respect to Securities of such series, such duties and only such duties as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(2) in the absence of negligence or willful misconduct on its part, the Trustee may, with respect to Securities of such series, conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture.

26

(b) In case an Event of Default with respect to Securities of any series has occurred and is continuing, the Trustee shall exercise, with respect to Securities of such series, such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs.

(c) No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that:

(1) this subsection shall not be construed to limit the effect of subsection (a) of this Section;

(2) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts;

(3) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders of a majority in principal amount of the Outstanding Securities of any series relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture with respect to the Securities of such series;

(4) no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it; and

(5) In no event shall the Trustee be responsible or liable for special, indirect, punitive or consequential loss or damage of any kind whatsoever (including but not limited to loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

(d) Whether or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section.

Section 602. Notice of Defaults. If a default occurs hereunder with respect to Securities of any series, the Trustee shall give the Holders of Securities of such series notice of such default as and to the extent provided by the Trust Indenture Act; provided, however, that in the case of any default of the character specified in Section 501(4) with respect to Securities of such series, no such notice to Holders shall be given until at least 30 days after the occurrence thereof. Except in the case of any default of the character specified in Section 501(1) or Section 501(2) with respect to Securities of such series, the Trustee may withhold notice if and so long as the Trustee in good faith determines that withholding notice is in the interest of the Holders. For the purpose of this Section 602, the term “default” means any event which is, or after notice or lapse of time or both would become, an Event of Default with respect to Securities of such series.

The Trustee shall not be required to take notice or be deemed to have notice or knowledge of any Event of Default with respect to the Securities of a series, except an Event of Default under Section 501(1) or Section 501(2) hereof (provided, that the Trustee is the principal Paying Agent with respect to the Securities of such series), unless a Responsible Officer has received written notice at the Corporate Trust Office of such Event of Default in accordance with Section 106 from the Company, any Subsidiary or the Holder of any Security, which notice states that the event referred to therein constitutes an Event of Default and references this Indenture and the relevant Securities.

27

Section 603. Certain Rights of Trustee. Subject to Sections 315(a) through 315(d) of the Trust Indenture Act:

(a) the Trustee may rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties;

Section 611. Acceptance of Appointment by Successor.

(a) In case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment. Thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or on the request of the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder; provided, that such property and money shall continue to be subject to any lien in favor of the retiring Trustee provided for in Section 607.

(b) In case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series, the Company, the retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall execute and deliver an indenture supplemental hereto wherein each successor Trustee shall accept such appointment and which (1) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and (3) shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee; and upon the execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates; but, on request of the Company or on the request of any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder, subject nevertheless to its lien provided for in Section 607, with respect to the Securities of that or those series to which the appointment of such successor Trustee relates.

(c) Upon request of any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in paragraph (a) or (b) of this Section, as the case may be.

(d) No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article.

Section 612. Merger, Conversion, Consolidation or Succession to Business. Any Person into which the Trustee may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any Person succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, if such Person shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities.

Section 613. Preferential Collection of Claims Against Company. If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Securities), the Trustee shall be subject to the provisions of Section 311 and any other provision of the Trust Indenture Act regarding the collection of claims against the Company (or any such other obligor).

31

Section 614. Appointment of Authenticating Agent. At any time when any of the Securities remain Outstanding, the Trustee may appoint an Authenticating Agent or Agents with respect to one or more series of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities of such series issued upon exchange, registration of transfer or partial redemption thereof or pursuant to Section 306, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a Corporation organized and doing business under the laws of the United States of America, any State thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus (computed in accordance with Section 310(a)(2) of the Trust Indenture Act) of not less than $50,000,000 and subject to supervision or examination by Federal, State or District of Columbia authority. If such Corporation publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section.

Any Corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any Corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any Corporation succeeding to the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, if such Corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.

An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall mail written notice of such appointment by first-class mail, postage prepaid, to all Holders of Securities of the series with respect to which such Authenticating Agent will serve, as their names and addresses appear in the Security Register. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

The provisions of Sections 308, 604 and 605 shall be applicable to each Authenticating Agent.

If an appointment with respect to one or more series is made pursuant to this Section, the Securities of such series may have endorsed thereon, in addition to the Trustee’s certificate of authentication, an alternate certificate of authentication in the following form:

This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

Whenever the Company shall have one or more Paying Agents for any series of Securities, it will, on or prior to each due date of the principal of (and premium, if any) or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay the principal (and premium, if any) or interest so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal, premium or interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act.

The Company will cause each Paying Agent for any series of Securities other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will:

(1) hold all sums held by it for the payment of the principal of (and premium, if any) or interest on Securities of that series in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided;

(2) give the Trustee notice of any default by the Company (or any other obligor upon the Securities of that series) in the making of any payment of principal of (and premium, if any) or interest on the Securities of that series; and

(3) at any time during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent.

The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Order of the Company direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same terms as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such sums.

Any sums deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of (and premium, if any) or interest on any Security of any series and remaining unclaimed for two years after such principal (and premium, if any) or interest has become due and payable shall be paid to the Company on Request of the Company, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be mailed to each such Holder notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication or mailing, any unclaimed balance of such money then remaining will be repaid to the Company.

Section 1004. Additional Amounts. If the Securities of a series provide for the payment of additional amounts, the Company will pay to the Holder of any Security of any series additional amounts as provided therein. Whenever in this Indenture there is mentioned, in any context, the payment of principal of (or premium, if any) or interest on, or in respect of, any Security of any series or the net proceeds received on the sale or exchange of any Security of any series, such mention shall be deemed to include mention of the payment of additional amounts provided for in this Section to the extent that, in such context, additional amounts are, were or would be payable in respect thereof pursuant to the provisions of this Section and express mention of the payment of additional amounts (if applicable) in any provisions hereof shall not be construed as excluding additional amounts in those provisions hereof where such express mention is not made.

If the Securities of a series provide for the payment of additional amounts, at least 10 days prior to the first Interest Payment Date with respect to that series of Securities (or if the Securities of that series will not bear interest prior to Maturity, the first day on which a payment of principal (and premium, if any) is made), and at least 10 days prior to each date of payment of principal (and premium, if any) or interest if there has been any change with respect to the matters set forth in the below-mentioned Officers’ Certificate, the Company will furnish the Trustee and the Company’s principal Paying Agent or Paying Agents, if other than the Trustee, with an Officers’ Certificate instructing the Trustee and such Paying Agent or Paying Agents whether such payment of principal of (and premium, if any) or interest on the Securities of that series shall be made to Holders of Securities of that series who are United States Aliens without withholding for or on account of any tax, assessment or other governmental charge

38

described in the Securities of that series. If any such withholding shall be required, then such Officers’ Certificate shall specify by country the amount, if any, required to be withheld on such payments to such Holders of Securities, and the Company will pay to the Trustee or such Paying Agent the additional amounts required by this Section. The Company covenants to indemnify the Trustee and any Paying Agent for, and to hold them harmless against, any loss, liability, claim, damage or expense reasonably incurred without negligence or willful misconduct on their part arising out of or in connection with actions taken or omitted by any of them in reliance on any Officers’ Certificate furnished pursuant to this Section.

Section 1006. Maintenance of Properties. The Company will cause all properties used or useful in the conduct of its business and in the business of the Subsidiaries to be maintained and kept in good condition, repair and working order and supplied with all necessary equipment and will cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all times; provided, that nothing in this Section shall prevent the Company from discontinuing the operation or maintenance of any of such properties or disposing of them if such discontinuance or disposal is, in the judgment of the Company, desirable in the conduct of its business or the business of the Subsidiaries and not disadvantageous in any material respect to the Holders of Securities.

Section 1007. Payment of Taxes and Other Claims. The Company will pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (1) all taxes, assessments and governmental charges levied or imposed upon it or any of the Subsidiaries, or upon the income, profits or property of the Company or any of the Subsidiaries, and (2) all lawful claims for labor, materials and supplies which, if unpaid, might by law become a lien upon the property of the Company or any of the Subsidiaries; provided, that none of the Company or any of the Subsidiaries shall be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings.

(c) If at any time the Company or any Subsidiary other than the Utilities shall issue, assume or guarantee any Debt secured by any mortgage and if subsection (a) of this Section 1008 requires that the Securities be secured equally and ratably with such Debt, the Company will promptly deliver to the Trustee an Officers’ Certificate stating that, and an Opinion of Counsel to the effect that, the covenant of the Company contained in subsection (a) of this Section has been complied with.

In case of any redemption at the election of the Company of all of the Securities of any series, the Company shall, at least 60 days prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee in writing of such Redemption Date. In case of any redemption at the election of the Company of less than all the Securities of any series, the Company shall, at least 60 days prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee in writing of such Redemption Date and of the principal amount of Securities of such series to be redeemed. In the case of any redemption of Securities (i) prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, or (ii) pursuant to an election of the Company which is subject to a condition specified in the terms of such Securities, the Company shall furnish the Trustee with an Officers’ Certificate evidencing compliance with such restriction or condition.

Section 1103. Selection by Trustee of Securities to Be Redeemed. If less than all the Securities of any series are to be redeemed, the particular Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee from the Outstanding Securities of such series (other than Securities of such series held by the Company), not previously called for redemption, by lot or by such other customary method prescribed by the Depositary, if applicable, and which may provide for the selection for redemption of portions (equal to the minimum authorized denomination for Securities of that series or any integral multiple thereof) of the principal amount of Securities of such series of a denomination larger than the minimum authorized denomination for Securities of that series; provided that any Securities to be redeemed held as a Global Security shall be selected in accordance with the policies and procedures of the Depositary, which may be made on a pass-through distribution of principal basis. Unless otherwise provided in the Securities of a series, partial redemptions must be in an amount not less than $1,000,000 principal amount of Securities.

The Trustee shall promptly notify the Company in writing of the Securities selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed.

(4) that on the Redemption Date the Redemption Price will become due and payable upon each such Security to be redeemed and, if applicable, that interest thereon will cease to accrue on and after said date,

(5) the place or places where such Securities maturing after the Redemption Date, are to be surrendered for payment of the Redemption Price, which shall be the office or agency maintained by the Company in each Place of Payment pursuant to Section 1002, and

Section 1106. Securities Payable on Redemption Date. Notice of redemption having been given as aforesaid, and the conditions, if any, set forth in such notice having been satisfied, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price, together with accrued interest, if any, to the Redemption Date; provided, that installments of interest on Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 307.

If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal (and premium, if any) shall, until paid, bear interest from the Redemption Date at the rate prescribed therefor in the Security.

42

Section 1107. Securities Redeemed in Part. Any Security which is to be redeemed only in part shall be surrendered at a Place of Payment therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities of the same series, Stated Maturity and of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered.

Such Securities shall be received and credited for such purpose by the Trustee at the Redemption Price specified in such Securities for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly.

Section 1203. Redemption of Securities for Sinking Fund. Not less than 60 days prior to each sinking fund payment date for any series of Securities, the Company will deliver to the Trustee an Officers’ Certificate specifying the amount of the next ensuing sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivering and crediting Securities of that series pursuant to Section 1202 and stating the basis for such credit and that such Securities have not previously been so credited and will also deliver to the Trustee any Securities to be so delivered.

As used in this Supplemental Indenture, terms defined in the Base Indenture or in the preamble or recitals hereto are used as so defined. The words “herein,” “hereof” and “hereby” and other words of similar import used in this Supplemental Indenture refer to this Supplemental Indenture as a whole and not to any particular section hereof.

The following additional terms are hereby established for the purposes of this Supplemental Indenture and shall have the meanings set forth in this Supplemental Indenture solely for the purposes of this Supplemental Indenture:

If the Five-year U.S. Treasury Rate cannot be determined pursuant to the methods described in clause (i) or (ii) above, then the Five-year U.S. Treasury Rate will be the same interest rate determined for the prior Reset Interest Determination Date or, if the Five-year U.S. Treasury Rate cannot be so determined as of the Reset Interest Determination Date preceding the First Reset Date, then the interest rate applicable for the Reset Period beginning on and including the First Reset Date will be deemed to be 6.950% per annum, which is the same interest rate as in effect from and including the Original Issue Date to, but excluding, the First Reset Date.

ARTICLE 2

DESIGNATION OF THE NOTES

Section 2.1 Designation and Principal Amount.

(a) Pursuant to the terms hereof and Section 301 of the Base Indenture, NiSource hereby establishes a series of Securities designated as the “6.950% Fixed-to-Fixed Reset Rate Junior Subordinated Notes due 2054”, the principal amount of which to be issued shall be in accordance with Section 2.1(b) and the form and terms of which shall be as set forth hereinafter.

(b) The Notes shall be issued in an initial aggregate principal amount of $500,000,000.

3

consolidated and form a single series with, and shall have the same terms as to status, redemption or otherwise as, the Notes authenticated and delivered on the date hereof. Such additional Notes will have the same CUSIP number as the Notes being authenticated on the date hereof, provided that such additional Notes must be part of the same issue as the Notes being authenticated on the date hereof for U.S. federal income tax purposes or, if they are not part of the same issue for such purposes, such additional Notes must be issued with a separate CUSIP number. No additional Notes may be issued if an Event of Default has occurred and is continuing with respect to the Notes.

Section 2.2 Form of the Notes. The Notes shall be issued in the form of one or more Global Securities substantially in the form attached in Exhibit A hereto, which is hereby incorporated in and expressly made a part of this Supplemental Indenture. The Trustee’s certificate of authentication for such Notes shall be substantially in the form required by Section 202 of the Base Indenture. The Notes shall bear the legend set forth in Exhibit A.

Section 2.3 Maturity Date of the Notes. The Notes will mature on November 30, 2054 (the “Maturity Date”), subject to earlier redemption at NiSource’s option as set forth in Article 6.

Section 2.4 Interest on the Notes. The Notes will bear interest (i) from and including the Original Issue Date to, but excluding, November 30, 2029 (the “First Reset Date”) at the rate of 6.950% per annum and (ii) from and including the First Reset Date, during each Reset Period at a rate per annum equal to the Five-year U.S. Treasury Rate as of the most recent Reset Interest Determination Date plus a spread of 2.451%, to be reset on each Reset Date. Interest on the Notes will accrue from the Original Issue Date and will be payable semi-annually in arrears on May 30 and November 30 (each, an “interest payment date”) of each year, beginning on November 30, 2024, to Holders at the close of business on the record date for the applicable interest payment date, which will be (i) the business day immediately preceding such interest payment date so long as all of the Notes remain in book-entry only form or (ii) the 15th calendar day preceding such interest payment date (whether or not a business day) if any of the Notes do not remain in book-entry only form (each, a “record date”), subject to NiSource’s right to defer interest payments as described in Article 5 below. Interest on the Notes will be computed on the basis of a 360-day year of twelve 30-day months.

The applicable interest rate for each Reset Period will be determined by the calculation agent, as of the applicable Reset Interest Determination Date. Promptly upon such determination, the calculation agent will notify NiSource of the interest rate for the Reset Period and NiSource will promptly notify, or cause the calculation agent to promptly notify, in writing, the Trustee and each paying agent of such interest rate. The calculation agent’s determination of any interest rate, and its calculation of the amount of interest for any Interest Payment Period beginning on or after the First Reset Date, will be on file at NiSource’s principal offices, will be made available to any Holder or beneficial owner of the Notes upon request and will be final and binding in the absence of manifest error.

If an interest payment date, redemption date, or Maturity Date falls on a day that is not a business day, payment will be made on the next succeeding business day with the same force and effect as if made on such payment date.

Section 2.5 Minimum Denominations. The Notes shall be issued in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

Section 2.6 No Sinking Fund. No sinking fund is provided for the Notes.

Section 2.7 Paying Agent and Security Registrar. The Trustee is hereby appointed as initial Paying Agent and initial Security Registrar for the Notes. The Notes shall be payable at the Corporate Trust Office of the Trustee.

Section 2.8 Other Terms of the Notes. The other terms of the Notes shall be as expressly set forth herein and in Exhibit A hereto.

Upon payment or distribution of assets of NiSource referred to in this Article, the Trustee and the Holders of the Notes shall be entitled to rely upon any order or decree made by any court of competent jurisdiction in which any such dissolution, winding-up, liquidation or reorganization proceeding affecting the affairs of NiSource is pending or upon a certificate of the trustee in bankruptcy, receiver, assignee for the benefit of creditors, liquidating trustee or agent or other person making any payment or distribution, delivered to the Trustee or to the Holders of the Notes, for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the holders of the Senior Indebtedness and other indebtedness of NiSource, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article.

The Trustee shall be entitled to rely on the delivery to it of a written notice by a Person representing itself to be a holder of Senior Indebtedness (or a trustee or representative on behalf of such holder) to establish that such notice has been given by a holder of Senior Indebtedness or a trustee or representative on behalf of any such holder or holders. In the event that the Trustee determines in good faith that further evidence is required with respect to the right of any Person as a holder of Senior Indebtedness to participate in any payment or distribution pursuant to this Article, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such Person under this Article, and, if such evidence is not furnished, the Trustee may defer payment to such Person pending judicial determination as to the right of such Person to receive such payment.

Section 3.5 Payments on the Notes Permitted. Nothing contained in this Article or elsewhere in this Supplemental Indenture or in the Notes shall affect the obligations of NiSource to make, or prevent NiSource from making, payment of the principal of or any premium or interest on the Notes in accordance with the provisions hereof and thereof, except as otherwise provided in this Article.

Section 3.6 Effectuation of Subordination by Trustee. Each Holder of the Notes, by his acceptance thereof, authorizes and directs the Trustee in his, her or its behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in this Article and appoints the Trustee his, her or its attorney-in-fact, as the case maybe, for any and all such purposes.

Section 3.7 Rights of Holders of Senior Indebtedness Not Impaired. No right of any present or future holder of any Senior Indebtedness shall at any time or in any way be prejudiced or impaired by any act or failure to act on the part of NiSource or by any noncompliance by NiSource with the terms, provisions and covenants of the Indenture, regardless of any knowledge thereof which any such holder may have or be otherwise charged with.

With respect to the holders of Senior Indebtedness, (i) the duties and obligations of the Trustee shall be determined solely by the express provisions of the Indenture; (ii) the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in the Indenture; (iii) no implied covenants or obligations shall be read into the Indenture against the Trustee; and (iv) the Trustee shall not be deemed to be a fiduciary as to such holders of Senior Indebtedness.

ARTICLE 4

ACCELERATION OF MATURITY

Section 4.1 Acceleration of Maturity. Notwithstanding the provisions of Section 502 of the Base Indenture, neither the Trustee nor the Holders of the Notes shall be entitled to declare the principal of or accrued and unpaid interest on the Notes to be immediately due and payable by reason of the occurrence and continuation of an Event of Default specified in clause (4) of Section 501 of the Base Indenture, and any notice of declaration of acceleration based on such an Event of Default shall be null and void with respect to the Notes; provided that, notwithstanding the foregoing, so long as an Event of Default specified in clause (4) of Section 501 of the Base Indenture with respect to the Notes shall have occurred and shall be continuing, the Trustee and the Holders of the Notes may exercise the other rights and remedies available under the Indenture in connection with such Event of Default, as well as such other rights and remedies as may be available under applicable law or otherwise.

ARTICLE 5

OPTION TO DEFER INTEREST AND COVENANTS

Section 5.1 Option to Defer Interest Payments. So long as no Event of Default with respect to the Notes has occurred and is continuing, NiSource may, at its option, defer interest payments on the Notes, from time to time, for one or more deferral periods of up to 20 consecutive Interest Payment Periods (each such deferral period, commencing on the interest payment date on which the first such deferred interest payment otherwise would have been made, an “Optional Deferral Period”), except that no such Optional Deferral Period may extend beyond the final maturity date of the Notes or end on a day other than the day immediately preceding an interest payment date. During any Optional Deferral Period, interest on the Notes will continue to accrue at the then-applicable interest rate on the Notes (as reset from time to time on any Reset Date occurring during such Optional Deferral Period in accordance with the terms of the Notes). In addition, during any Optional Deferral Period, interest on the deferred interest (“compound interest”) will accrue at the then-applicable interest rate on the Notes (as reset from time to time on any Reset Date occurring during such Optional Deferral Period in accordance with the terms of the Notes), compounded semi-annually, to the extent permitted by applicable law. No interest will be due or payable on the Notes during an Optional Deferral Period, except upon a redemption of any Notes on any redemption date during such Optional Deferral Period (in which case all accrued and unpaid interest (including, to the extent permitted by applicable law, any compound interest) on the Notes to be redeemed to, but excluding, such redemption date will be due and payable on such redemption date), or unless the principal of and interest on the Notes shall have been declared due and payable as the result of an Event of Default with respect to the Notes (in which case all accrued and unpaid interest, including, to the extent permitted by applicable law, any compound interest, on the Notes shall become due and payable). All references in the Notes and, insofar as relates to the Notes, the Indenture, to “interest” on the Notes shall be deemed to include any such deferred interest and, to the extent permitted by applicable law, any compound interest, unless otherwise expressly stated or the context otherwise requires.

Before the end of any Optional Deferral Period that is shorter than 20 consecutive Interest Payment Periods, NiSource may elect, at its option, to extend such Optional Deferral Period, so long as the entire Optional Deferral Period does not exceed 20 consecutive Interest Payment Periods or extend beyond the final maturity date of the Notes. NiSource may also elect, at its option, to shorten the length of any Optional Deferral Period. No Optional Deferral Period (including as extended or shortened) may end on a day other than the day immediately preceding an interest payment date. At the end of any Optional Deferral Period, if all amounts then due on the Notes, including all accrued and unpaid interest thereon (including, without limitation and to the extent permitted by applicable law, any compound interest), are paid, NiSource may elect to begin a new Optional Deferral Period; provided, however, that, without limitation of the foregoing, NiSource may not begin a new Optional Deferral Period unless NiSource has paid all accrued and unpaid interest on the Notes (including, without limitation and to the extent permitted by applicable law, any compound interest) from any previous Optional Deferral Periods.

Section 5.2 Covenants. During any Optional Deferral Period, NiSource will not do any of the following:

8

provided; however, during an Optional Deferral Period, NiSource may (a) declare and pay dividends or distributions payable solely in shares of NiSource common stock (together, for the avoidance of doubt, with cash in lieu of any fractional share) or options, warrants or rights to subscribe for or purchase shares of NiSource common stock, (b) declare and pay any dividend in connection with the implementation of a plan (a “Rights Plan”) providing for the issuance by NiSource to all holders of NiSource common stock of rights entitling them to subscribe for or purchase common stock or any class or series of NiSource preferred stock, which rights (1) are deemed to be transferred with such common stock, (2) are not exercisable until the occurrence of a specified event or events and (3) are also issued in respect of future issuances of NiSource common stock, (c) issue any of shares of NiSource Capital Stock under any Rights Plan or redeem or repurchase any rights distributed pursuant to a Rights Plan, (d) reclassify NiSource Capital Stock or exchange or convert one class or series of NiSource Capital Stock for another class or series of NiSource Capital Stock, (e) purchase fractional interests in shares of NiSource Capital Stock pursuant to the conversion or exchange provisions of such Capital Stock or the security being converted or exchanged, (f) purchase, acquire or withhold shares of NiSource common stock related to the issuance of NiSource common stock or rights under any dividend reinvestment plan or related to any of NiSource benefit plans for NiSource directors, officers, employees, consultants or advisors, including any employment contract, and (g) for the avoidance of doubt, convert convertible Capital Stock of NiSource into other Capital Stock of NiSource in accordance with the terms of such convertible Capital Stock (together, for the avoidance of doubt, with cash in lieu of any fractional share).

Section 5.3 Notice of Deferral. NiSource will give the Holders of the Notes and the Trustee written notice of its election of, or any shortening or extension of, an Optional Deferral Period at least 10 business days prior to the earlier of (1) the next succeeding interest payment date or (2) the date upon which NiSource is required to give notice to any applicable self-regulatory organization or to Holders of the Notes of the next succeeding interest payment date or the record date therefor. The record date for the payment of deferred interest and, to the extent permitted by applicable law, any compound interest payable on the interest payment date immediately following the last day of an Optional Deferral Period will be the regular record date with respect to such interest payment date.

ARTICLE 6

OPTIONAL REDEMPTION BY NISOURCE

Section 6.1 Optional Redemption. NiSource may redeem some or all of the Notes, at its option, in whole or in part (i) on any day in the period commencing on the date falling 90 days prior to the First Reset Date and ending on and including the First Reset Date and (ii) after the First Reset Date, on any interest payment date, at a redemption price in cash equal to 100% of the principal amount of the Notes being redeemed, plus, (subject to the provisions set forth in Section 6.4 regarding the payment of installments of interest on the Notes that are due and payable on any Interest Payment Date falling on or prior to a Redemption Date), accrued and unpaid interest on the Notes to be redeemed to, but excluding, the redemption date.

Section 6.2 Redemption Following a Tax Event. NiSource may at its option redeem the Notes, in whole but not in part, at any time following the occurrence and during the continuance of a Tax Event at a redemption price in cash equal to 100% of the principal amount of the Notes, plus, (subject to the provisions set forth in Section 6.4 regarding the payment of installments of interest on the Notes that are due and payable on any Interest Payment Date falling on or prior to a Redemption Date), accrued and unpaid interest on the Notes to, but excluding, the redemption date.

Section 6.3 Redemption Following a Rating Agency Event. NiSource may at its option redeem the Notes, in whole but not in part, at any time following the occurrence and during the continuance of a Rating Agency Event at a redemption price in cash equal to 102% of the principal amount of the Notes, plus, (subject to the provisions set forth in Section 6.4 regarding the payment of installments of interest on the Notes that are due and payable on any Interest Payment Date falling on or prior to a Redemption Date), accrued and unpaid interest on the Notes to, but excluding, the redemption date.

Section 6.4 Payments of Interest. Notwithstanding any statement in Article 6 to the contrary, installments of interest on the Notes that are due and payable on any interest payment date falling on or prior to a redemption date for the Notes will be payable on that interest payment date to the Holders thereof as of the close of business on the relevant record date according to the terms of the Notes and the Indenture, except that, if the redemption date for any Notes falls on any day during an Optional Deferral Period, accrued and unpaid interest (including, to the extent permitted by applicable law, any compound interest) on such Notes will be paid on such redemption date to the persons entitled to receive the redemption price of such Notes. For the avoidance of doubt, the interest payment date falling immediately after the last day of an Optional Deferral Period shall not be deemed to fall on a day during such Optional Deferral Period.

Section 6.5 Securities Called for Redemption. Section 1106 of the Base Indenture is replaced in its entirety as follows:

“Once notice of redemption is mailed, the Notes called for redemption will become due and payable on the redemption date at the applicable redemption price, plus, subject to the terms described in Section 6.4 of this Supplemental Indenture, accrued and unpaid interest to, but excluding, the redemption date, and will be paid upon surrender thereof for redemption, unless (a) the notice of redemption provides that such redemption shall be subject to the condition described in Section 6.6 of this Supplemental Indenture and (b) such redemption shall have been canceled in accordance with the provisions of Section 6.6 of this Supplemental Indenture because such condition shall not have been satisfied. If only part of a note is redeemed, the Trustee will issue in the name of the registered holder of the note and deliver to such holder a new note in a principal amount equal to the unredeemed portion of the principal of the note surrendered for redemption. If the Company elects to redeem all or a portion of the Notes, then, unless otherwise provided in such notice of redemption as described in the next succeeding paragraph, the redemption will not be conditional upon receipt by the paying agent or the Trustee of monies sufficient to pay the redemption price.”

Section 6.6 Notice of Redemption. The following paragraph is appended as the last paragraph of Section 1104 of the Base Indenture:

“If, at the time a notice of redemption is given, (i) the Company has not effected satisfaction and discharge of the Notes pursuant to Article Four of the Indenture and (ii) such notice of redemption is not being given in connection with or in order to effect satisfaction and discharge of the Notes, then, if the notice of redemption so provides and at the Company’s option, the redemption may be subject to the condition that the Trustee shall have received, on or before the applicable redemption date, monies in an amount sufficient to pay the redemption price and accrued and unpaid interest on the Notes called for redemption to, but excluding, the redemption date. If monies in such amount are not received by the Trustee on or before such redemption date, such notice of redemption shall be automatically canceled and of no force or effect, such proposed redemption shall be automatically canceled and the Company shall not be required to redeem the Notes called for redemption on such redemption date. In the event that a redemption is canceled, the Company will, not later than the business day immediately following the proposed redemption date, deliver, or cause to be delivered, notice of such cancellation to the Holders of the Notes called for redemption (which notice will also indicate that any Notes or portions thereof surrendered for redemption shall be returned to the applicable Holders), and the Company will direct the Trustee to, and the Trustee will, promptly return any Notes or portions thereof that have been surrendered for redemption to the applicable Holders.”

Section 6.7 Deposit of Redemption Price. Section 1105 of the Base Indenture is deleted in its entirety and does not apply to the Notes.

6.950% Fixed-to-Fixed Reset Rate Junior Subordinated Notes due 2054

1. Interest

Interest on the Notes will accrue from the Original Issue Date and will be payable semi-annually in arrears on May 30 and November 30 (each, an “Interest Payment Date”) of each year, beginning on November 30, 2024, to Holders at the close of business on the Regular Record Date for the applicable Interest Payment Date, subject to the Company’s right to defer interest payments pursuant to the provisions set forth below.

Interest on the Notes will be computed on the basis of a 360-day year of twelve 30-day months.

The applicable interest rate for each Reset Period will be determined by the Calculation Agent (as defined below), as of the applicable Reset Interest Determination Date, in accordance with following provisions:

As provided above, the applicable interest rate for each Reset Period will be determined by the Calculation Agent, as of the applicable Reset Interest Determination Date. Promptly upon such determination, the Calculation Agent will notify the Company of the interest rate for the Reset Period and the Company will promptly notify, or cause the Calculation Agent to promptly notify, in writing, the Trustee and each Paying Agent of such interest rate. The Calculation Agent’s determination of any interest rate, and its calculation of the amount of interest for any Interest Payment Period beginning on or after the First Reset Date, will be on file at the Company’s principal offices, will be made available to any Holder or beneficial owner of the Notes upon request and will be final and binding in the absence of manifest error.

If an Interest Payment Date, redemption date, or Maturity Date falls on a day that is not a Business Day, payment will be made on the next succeeding Business Day with the same force and effect as if made on such payment date.

“Business Day” means, unless otherwise expressly stated, any day other than (i) a Saturday or Sunday or (ii) a day on which banks and trust companies in The City of New York are authorized or obligated by law, regulation or executive order to remain closed.

“Calculation Agent” means, at any time, the entity appointed by the Company and serving as such agent with respect to the Notes at such time. Unless the Company has validly called all of the outstanding Notes for redemption on a redemption date occurring prior to the First Reset Date, the Company will appoint a Calculation Agent for the Notes prior to the Reset Interest Determination Date immediately preceding the First Reset Date; provided that, if the Company has called all of the outstanding Notes for redemption on a redemption date occurring prior to the First Reset Date but the Company does not redeem all of the outstanding Notes on such redemption date, the Company will appoint a Calculation Agent for the Notes as promptly as practicable after such proposed redemption date. The Company may terminate any such appointment and may appoint a successor Calculation Agent at any time and from time to time (so long as there shall always be a Calculation Agent in respect of the Notes when so required). The Company may appoint itself or an affiliate of the Company as Calculation Agent.

“Five-year U.S. Treasury Rate” means, as of any Reset Interest Determination Date, (i) an interest rate (expressed as a decimal) determined to be the per annum rate equal to the arithmetic mean of the yields to maturity for U.S. Treasury securities adjusted to constant maturity with a maturity of five years from the next Reset Date and trading in the public securities markets, for the five consecutive Business Days immediately prior to the respective Reset Interest Determination Date as published (or, if

fewer than five consecutive Business Days are so published on the applicable Reset Interest Determination Date, for such number of Business Days published) in the most recent H.15, or (ii) if there is no such published U.S. Treasury security with a maturity of five years from the next Reset Date and trading in the public securities markets, then the rate will be determined by interpolation between the arithmetic mean of the yields to maturity for each of the two series of U.S. Treasury securities adjusted to constant maturity trading in the public securities markets, (A) one maturing as close as possible to, but earlier than, the Reset Date following the next succeeding Reset Interest Determination Date, and (B) the other maturing as close as possible to, but later than, the Reset Date following the next succeeding Reset Interest Determination Date, in each case for the five consecutive Business Days immediately prior to the respective Reset Interest Determination Date as published in the most recent H.15. If the Five-year U.S. Treasury Rate cannot be determined pursuant to the methods described in clause (i) or (ii) above, then the Five-year U.S. Treasury Rate will be the same interest rate determined for the prior Reset Interest Determination Date or, if the Five-year U.S. Treasury Rate cannot be so determined as of the Reset Interest Determination Date preceding the First Reset Date, then the interest rate applicable for the Reset Period beginning on and including the First Reset Date will be deemed to be 6.950% per annum, which is the same interest rate as in effect from and including the Original Issue Date to, but excluding, the First Reset Date.

“H.15” means the statistical release designated as such, or any successor publication, published by the Board of Governors of the U.S. Federal Reserve System (or any successor thereto).

“Interest Payment Period” means the semi-annual period from and including an Interest Payment Date to but excluding the next succeeding Interest Payment Date, except for the first Interest Payment Period which shall be the period from and including the Original Issue Date to but excluding November 30, 2024.

“most recent H.15” means the H.15 published closest in time but prior to the close of business on the second Business Day prior to the applicable Reset Date.

“redemption date” when used with respect to any Notes to be redeemed, means the date fixed for such redemption pursuant to the Indenture.

“Reset Date” means the First Reset Date and November 30 of every fifth year after 2029.

“Reset Interest Determination Date” means, in respect of any Reset Period, the day falling two Business Days prior to the first day of such Reset Period.

“Reset Period” means the period from and including the First Reset Date to, but excluding, the next following Reset Date and thereafter each period from and including a Reset Date to, but excluding, the next following Reset Date.

2. Optional Interest Deferral

So long as no Event of Default with respect to the Notes has occurred and is continuing, the Company may, at its option, defer interest payments on the Notes, from time to time, for one or more deferral periods of up to 20 consecutive Interest Payment Periods (each such deferral period, commencing on the interest payment date on which the first such deferred interest payment otherwise would have been made, an “Optional Deferral Period”), except that no such Optional Deferral Period may extend beyond the final maturity date of the Notes or end on a day other than the day immediately preceding an Interest Payment Date. During any Optional Deferral Period, interest on the Notes will continue to accrue at the then-applicable interest rate on the Notes (as reset from time to time on any Reset Date occurring during such Optional Deferral Period in accordance with the terms of the Notes). In addition, during any Optional Deferral Period, interest on the deferred interest (“compound interest”) will accrue at the then-applicable interest rate on the Notes (as reset from time to time on any Reset Date occurring during such Optional Deferral Period in accordance with the terms of the Notes), compounded

semi-annually, to the extent permitted by applicable law. No interest will be due or payable on the Notes during an Optional Deferral Period, except upon a redemption of any Notes on any redemption date during such Optional Deferral Period (in which case all accrued and unpaid interest (including, to the extent permitted by applicable law, any compound interest) on the Notes to be redeemed to, but excluding, such redemption date will be due and payable on such redemption date), or unless the principal of and interest on the Notes shall have been declared due and payable as the result of an Event of Default with respect to the Notes (in which case all accrued and unpaid interest, including, to the extent permitted by applicable law, any compound interest, on the Notes shall become due and payable). All references in the Notes and, insofar as it relates to the Notes, the Indenture, to “interest” on the Notes shall be deemed to include any such deferred interest and, to the extent permitted by applicable law, any compound interest, unless otherwise expressly stated or the context otherwise requires.

Before the end of any Optional Deferral Period that is shorter than 20 consecutive Interest Payment Periods, the Company may elect, at its option, to extend such Optional Deferral Period, so long as the entire Optional Deferral Period does not exceed 20 consecutive Interest Payment Periods or extend beyond the final maturity date of the Notes. The Company may also elect, at its option, to shorten the length of any Optional Deferral Period. No Optional Deferral Period (including as extended or shortened) may end on a day other than the day immediately preceding an Interest Payment Date. At the end of any Optional Deferral Period, if all amounts then due on the Notes, including all accrued and unpaid interest thereon (including, without limitation and to the extent permitted by applicable law, any compound interest), are paid, the Company may elect to begin a new Optional Deferral Period; provided, however, that, without limitation of the foregoing, the Company may not begin a new Optional Deferral Period unless the Company has paid all accrued and unpaid interest on the Notes (including, without limitation and to the extent permitted by applicable law, any compound interest) from any previous Optional Deferral Periods.

During any Optional Deferral Period, the Company will not do any of the following:

provided; however, during an Optional Deferral Period, the Company may (a) declare and pay dividends or distributions payable solely in shares of the Company’s common stock (together, for the avoidance of doubt, with cash in lieu of any fractional share) or options, warrants or rights to subscribe for or purchase shares of the Company’s common stock, (b) declare and pay any dividend in connection with the implementation of a plan (a “Rights Plan”) providing for the issuance by the Company to all holders of the Company’s common stock of rights entitling them to subscribe for or purchase common stock or any class or series of the Company’s preferred stock, which rights (1) are deemed to be transferred with such common stock, (2) are not exercisable until the occurrence of a specified event or events and (3) are also issued in respect of future issuances of the Company’s common stock, (c) issue any of shares of the Company’s Capital Stock under any Rights Plan or redeem or repurchase any rights distributed pursuant to a Rights Plan, (d) reclassify the Company’s Capital Stock or exchange or convert one class or series of the Company’s Capital Stock for another class or series of the Company’s Capital Stock, (e) purchase fractional interests in shares of the Company’s Capital Stock pursuant to the conversion or exchange provisions of such Capital Stock or the security being converted or exchanged, (f) purchase, acquire or withhold shares of the Company’s common stock related to the issuance of the Company’s common

stock or rights under any dividend reinvestment plan or related to any of the Company’s benefit plans for the Company’s directors, officers, employees, consultants or advisors, including any employment contract, and (g) for the avoidance of doubt, convert convertible Capital Stock of the Company into other Capital Stock of the Company in accordance with the terms of such convertible Capital Stock (together, for the avoidance of doubt, with cash in lieu of any fractional share).

The Company will give the Holders of the Notes and the Trustee notice of its election of, or any shortening or extension of, an Optional Deferral Period at least 10 Business Days prior to the earlier of (1) the next succeeding Interest Payment Date or (2) the date upon which the Company is required to give notice to any applicable self-regulatory organization or to Holders of the Notes of the next succeeding Interest Payment Date or the record date therefor. The record date for the payment of deferred interest and, to the extent permitted by applicable law, any compound interest payable on the Interest Payment Date immediately following the last day of an Optional Deferral Period will be the Regular Record Date with respect to such Interest Payment Date.

“Capital Stock” means (i) in the case of a corporation or a company, corporate stock or shares; (ii) in the case of an association or business entity, any and all shares, interests, participations, rights or other equivalents (however designated) of corporate stock; (iii) in the case of a partnership or limited liability company, partnership or membership interests (whether general or limited); and (iv) any other interest or participation that confers on a person the right to receive a share of the profits and losses of, or distributions of assets of, the issuing person.

3. Subordination

The indebtedness represented by the Notes and the payment of the principal of and any premium or interest on each and all of the Notes of such series is subordinate in right of payment to the prior payment in full of all Senior Indebtedness (as defined below), to the extent set forth in the Indenture. Senior Indebtedness shall continue to be Senior Indebtedness with respect to the Notes irrespective of any amendment, modification or waiver of any term of the Notes or extension or renewal of the Notes (other than any such amendment, modification or waiver that makes the Notes subordinated or equal in right of payment to the Notes).

“Senior Indebtedness” means, with respect to the Notes, (i) indebtedness of the Company, whether outstanding at the date of the indenture or incurred, created or assumed after such date, (a) in respect of money borrowed by the Company (including any financial derivative, hedging or futures contract or similar instrument, to the extent any such item is primarily a financing transaction) and (b) evidenced by debentures, bonds, notes, credit or loan agreements or other similar instruments or agreements issued or entered into the Company; (ii) all finance lease obligations of the Company; (iii) all obligations of the Company issued or assumed as the deferred purchase price of property, all conditional sale obligations of the Company and all obligations of the Company under any title retention agreement (but excluding, for the avoidance of doubt, trade accounts payable arising in the ordinary course of business and long-term purchase obligations); (iv) all obligations of the Company for the reimbursement of any letter of credit, banker’s acceptance, security purchase facility or similar credit transaction; and (v) all obligations of the type referred to in clauses (i) through (iv) above of other persons for the payment of which the Company is responsible or liable as obligor, guarantor or otherwise, except for any obligations, instruments or agreements of the type referred to in any of clauses (i) through (v) above that, by the terms of the instruments or agreements creating or evidencing the same or pursuant to which the same is outstanding, are subordinated or equal in right of payment to the Notes.

4. Method of Payment

The Company will pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders of Notes at the close of business on the Regular Record Date next preceding each Interest Payment Date even if Notes are canceled after the Regular Record Date and on or before the Interest Payment Date. Holders must surrender Notes to a Paying Agent to collect principal payments. The Company will pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. Payments in respect of the Notes represented by a Global Security (including principal, premium, if any, and interest) will be made by wire transfer of immediately available funds to the accounts specified by DTC, as Depositary.

5. Paying Agent and Security Registrar

Initially, the Trustee will act as Paying Agent and Security Registrar. The Company may appoint and change any Paying Agent or Security Registrar without notice to the Holders. The Company may act as Paying Agent or Security Registrar.

6. Indenture

The Company issued the Notes under an Indenture dated as of May 16, 2024 (the “Base Indenture”), by and between the Company and The Bank of New York Mellon, a New York banking corporation, not in its individual capacity but solely as trustee (the “Trustee”), as supplemented by a First Supplemental Indenture dated as of May 16, 2024 (the “Supplemental Indenture”), by and between the Company and the Trustee (the Base Indenture, as amended and supplemented by the Supplemental Indenture, the “Indenture”). The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. sections 77aaa-77bbbb) as in effect on the date of the Supplemental Indenture (the “Act”). Capitalized terms used herein and defined in the Indenture but not defined herein have the respective meanings ascribed thereto in the Indenture. The Notes are subject to all such terms, and Holders of Notes are referred to the Indenture and the Act for a statement of those terms.

The Notes issued on the Original Issue Date will be treated as a single class for all purposes under the Indenture.

7. Optional Redemption

The Company may redeem some or all of the Notes, at its option, in whole or in part (i) on any day in the period commencing on the date falling 90 days prior to the First Reset Date and ending on and including the First Reset Date and (ii) after the First Reset Date, on any interest payment date, at a redemption price in cash equal to 100% of the principal amount of the Notes being redeemed, plus, (subject to the provisions set forth in the Indenture regarding the payment of installments of interest on the Notes that are due and payable on any Interest Payment Date falling on or prior to a redemption date), accrued and unpaid interest on the Notes to be redeemed to, but excluding, the redemption date.

The Company may at its option redeem the Notes, in whole but not in part, at any time following the occurrence and during the continuance of a Tax Event (as defined below) at a redemption price in cash equal to 100% of the principal amount of the Notes, plus, (subject to the provisions set forth in the Indenture regarding the payment of installments of interest on the Notes that are due and payable on any Interest Payment Date falling on or prior to a redemption date), accrued and unpaid interest on the Notes to, but excluding, the redemption date.

“Tax Event” means that the Company has received an opinion of counsel experienced in such matters to the effect that, as a result of:

(i) any amendment to, clarification of, or change, including any announced prospective change, in the laws or treaties of the United States or any of its political subdivisions or taxing authorities, or any regulations under those laws or treaties;

(ii) an administrative action, which means any judicial decision or any official administrative pronouncement, ruling, regulatory procedure, notice or announcement, including any notice or announcement of intent to issue or adopt any administrative pronouncement, ruling, regulatory procedure or regulation;

(iii) any amendment to, clarification of, or change in the official position or the interpretation of any administrative action or judicial decision or any interpretation or pronouncement that provides for a position with respect to an administrative action or judicial decision that differs from the previously generally accepted position, in each case by any legislative body, court, governmental authority or regulatory body, regardless of the time or manner in which that amendment, clarification or change is introduced or made known; or

(iv) a threatened challenge asserted in writing in connection with a tax audit of the Company or any of its subsidiaries, or a publicly-known threatened challenge asserted in writing against any other taxpayer that has raised capital through the issuance of securities that are substantially similar to the Notes,

which amendment, clarification or change is effective or the administrative action is taken or judicial decision, interpretation or pronouncement is issued or threatened challenge is asserted or becomes publicly-known after May 13, 2024, there is more than an insubstantial risk that interest payable by the Company on the Notes is not deductible, or within 90 days would not be deductible, in whole or in part, by the Company for United States federal income tax purposes.

The Company may at its option redeem the Notes, in whole but not in part, at any time following the occurrence and during the continuance of a Rating Agency Event (as defined below) at a redemption price in cash equal to 102% of the principal amount of the Notes, plus, (subject to the provisions set forth in the Indenture regarding the payment of installments of interest on the Notes that are due and payable on any Interest Payment Date falling on or prior to a redemption date), accrued and unpaid interest on the Notes to, but excluding, the redemption date.

“Rating Agency Event” means, as of any date, a change, clarification or amendment in the methodology published by any nationally recognized statistical rating organization within the meaning of Section 3(a)(62) of the Securities Exchange Act of 1934, as amended (or any successor provision thereto), that then publishes a rating for the Company (together with any successor thereto, a “rating agency”) in assigning equity credit to securities such as the Notes, (a) as such methodology was in effect on May 13, 2024, in the case of any rating agency that published a rating for the Company as of May 13, 2024, or (b) as such methodology was in effect on the date such rating agency first published a rating for the Company, in the case of any rating agency that first publishes a rating for the Company after May 13, 2024 (in the case of either clause (a) or (b), the “current methodology”), that results in (i) any shortening of the length of time for which a particular level of equity credit pertaining to the Notes by such rating agency would have been in effect had the current methodology not been changed or (ii) a lower equity credit (including up to a lesser amount) being assigned by such rating agency to the Notes as of the date of such change, clarification or amendment than the equity credit that would have been assigned to the Notes by such rating agency had the current methodology not been changed.

The Trustee shall have no duty to calculate the redemption price.

8. Notice of Redemption

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the redemption date to each Holder of Notes to be redeemed in accordance with Section 106 of the Indenture. In the case of a partial redemption, selection of the Notes for redemption will be made by lot or by such other customary method prescribed by the depositary. No Notes of a principal amount of $2,000 or less will be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that relates to such Note will state the portion of the principal amount of the Note to be redeemed. A new Note in a principal amount equal to the unredeemed portion of the original Note will be issued in the name of the

Holder of the original Note upon surrender for cancellation of the original Note. For so long as the Notes are held by DTC (or another depositary), the redemption of the Notes shall be done in accordance with the policies and procedures of the depositary, which may be on a pro rata pass-through distribution of principal basis. Unless the Company defaults in payment of the redemption price, on and after the redemption date interest will cease to accrue on the Notes or portions thereof called for redemption.

If, at the time a notice of redemption is given, (i) the Company has not effected satisfaction and discharge of the Notes pursuant to Article Four of the Indenture and (ii) such notice of redemption is not being given in connection with or in order to effect satisfaction and discharge of the Notes, then, if the notice of redemption so provides and at the Company’s option, the redemption may be subject to the condition that the Trustee shall have received, on or before the applicable redemption date, monies in an amount sufficient to pay the redemption price and accrued and unpaid interest on the Notes called for redemption to, but excluding, the redemption date. If monies in such amount are not received by the Trustee on or before such redemption date, such notice of redemption shall be automatically canceled and of no force or effect, such proposed redemption shall be automatically canceled and the Company shall not be required to redeem the Notes called for redemption on such redemption date. In the event that a redemption is canceled, the Company will, not later than the business day immediately following the proposed redemption date, deliver, or cause to be delivered, notice of such cancellation to the Holders of the Notes called for redemption (which notice will also indicate that any Notes or portions thereof surrendered for redemption shall be returned to the applicable Holders), and the Company will direct the Trustee to, and the Trustee will, promptly return any Notes or portions thereof that have been surrendered for redemption to the applicable Holders.

9. Additional Notes

The Company may, without the consent of the Holders of the Notes, create and issue additional Notes ranking equally with the Notes in all respects, including having the same terms (except for the price to public, the issue date and the initial interest accrual date and the first Interest Payment Date, as applicable), so that such additional Notes shall be consolidated and form a single series with the Notes and shall have the same terms as to status, redemption or otherwise as the Notes. Such additional Notes will have the same CUSIP number as the Notes being authenticated on the date hereof, provided that such additional Notes are part of the same issue as the Notes being authenticated on the date hereof for U.S. federal income tax purposes. If such additional Notes are not part of the same issue for U.S. federal income tax purposes, such additional Notes must be issued with a separate CUSIP number. No additional Notes may be issued if an Event of Default has occurred and is continuing with respect to the Notes.

10. Denominations; Transfer; Exchange

The Notes are in registered form without coupons in denominations of $2,000 principal amount and integral multiples of $1,000. A Holder may transfer or exchange Notes in accordance with the Indenture. The Security Registrar may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Security Registrar need not register the transfer or exchange of any Notes selected for redemption (except, in the case of a Note to be redeemed in part, the portion of the Note not to be redeemed) for a period of fifteen (15) Business Days before a selection of Notes to be redeemed.

11. Persons Deemed Owners

The registered Holder of this Note may be treated as the owner of it for all purposes.

12. Unclaimed Money

If money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at its request. After any such payment, Holders entitled to the money must look only to the Company and not to the Trustee or the Paying Agent for payment.

13. Satisfaction and Discharge

Under the Indenture, the Company can terminate its obligations with respect to the Notes not previously delivered to the Trustee for cancellation when those Notes have become due and payable or will become due and payable at their Stated Maturity within one year or are to be called for redemption within one year under arrangements satisfactory to the Trustee for giving notice of redemption. The Company may terminate its obligations with respect to the Notes by depositing with the Trustee, as funds in trust dedicated solely for that purpose, an amount sufficient to pay and discharge the entire indebtedness on the Notes. In that case, the Indenture will cease to be of further effect and the Company’s obligations will be satisfied and discharged with respect to the Notes (except as to the Company’s obligations to pay all other amounts due under the Indenture and to provide certain Officers’ Certificates and Opinions of Counsel to the Trustee). At the expense of the Company, the Trustee will execute proper instruments acknowledging the satisfaction and discharge.

14. Amendment, Waiver

Subject to certain exceptions set forth in the Indenture, (i) the Indenture may be amended with the written consent of the Holders of a majority in principal amount of the then Outstanding Securities of each series affected by such amendment, (ii) the Notes may be amended with the written consent of the Holders of at least a majority in principal amount of the Outstanding Notes and (iii) any default or noncompliance with any provision may be waived with the written consent of the Holders of a majority in principal amount of the Outstanding Notes. Subject to certain exceptions set forth in the Indenture, without the consent of any Holder, the Company and the Trustee shall be entitled to amend the Indenture to, among other things, cure any ambiguity, defect or inconsistency, or to evidence the succession of another Person as obligor under the Indenture, or to add to the Company’s covenants or to surrender any right or power conferred on the Company under the Indenture, or to add events of default, or to secure the Notes, or to evidence or provide for the acceptance or appointment by a successor Trustee or facilitate the administration of the trusts under the Indenture by more than one trustee, or to conform the Indenture to any amendment of the Act.

15. Defaults and Remedies

Under the Indenture, Events of Default include: (i) a default by the Company in the payment of any interest upon any Note and the continuance of such default for 60 days; (ii) a default by the Company in the payment of principal of or any premium on any Note when due at Maturity, on redemption, by declaration or otherwise, and the continuance of such default for three (3) Business Days; (iii) a default by the Company in the performance of or breach of any covenant or warranty in the Indenture and continuance of such default for 90 days after written notice has been given to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 33% in principal amount of the Outstanding Notes; (iv) a default by the Company under any bond, debenture, note or other evidence of indebtedness for money borrowed by the Company, or the Company defaults under any mortgage, indenture or instrument under which there may be issued, secured or evidenced indebtedness constituting a failure to pay in excess of $50,000,000 of the principal or interest when due and payable, subject to certain cure rights; or (v) certain events of bankruptcy, insolvency or reorganization involving the Company. If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 33% in principal amount of the Outstanding Notes may declare all the Notes to be due and payable immediately.

Neither the Trustee nor the Holders of the Notes shall be entitled to declare the principal of or accrued and unpaid interest on the Notes to be immediately due and payable by reason of the occurrence and continuation of an Event of Default specified in clause (4) of Section 501 of the Base Indenture, and any notice of declaration of acceleration based on such an Event of Default shall be null and void with respect to the Notes; provided that, notwithstanding the foregoing, so long as an Event of Default specified in clause (4) of Section 501 of the Base Indenture with respect to the Notes shall have occurred and shall be continuing, the Trustee and the Holders of the Notes may exercise the other rights and remedies available under the Indenture in connection with such Event of Default, as well as such other rights and remedies as may be available under applicable law or otherwise.

Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Notes unless it receives indemnity or security satisfactory to it. Subject to certain limitations, Holders of a majority in principal amount of the Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing default (except a default in payment of principal or interest) if it determines that withholding notice is in the interest of the Holders.

16. Trustee Dealings with the Company

Subject to certain limitations imposed by the Act, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee.

17. No Recourse Against Others

A director, officer, employee or stockholder, as such, of the Company or the Trustee shall not have any liability for any obligations of the Company under the Notes or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Note, each Holder waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Notes.

18. Authentication

This Note shall not be valid until an authorized signatory of the Trustee (or an Authenticating Agent) signs the certificate of authentication on the other side of this Note in accordance with requirements set forth in the Indenture and the Officers’ Certificate.

19. Abbreviations

Customary abbreviations may be used in the name of a Holder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with rights of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors Act).

20. CUSIP and ISIN Numbers

Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused the applicable CUSIP number to be printed on the Notes and has directed the Trustee to use such CUSIP number in any notice of redemption as a convenience to the Holders. To the extent such number has been issued, the Company has caused the applicable ISIN number to be similarly printed on the Notes and has similarly instructed the Trustee. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.

21. Governing Law.

THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO CONTRARY CONFLICT OF LAWS OR CHOICE OF LAWS PROVISIONS OF THE STATE OF NEW YORK OR ANY OTHER JURISDICTION.

(a) Indemnification and Change of Control. The enforceability of any agreement relating to (i) indemnification, contribution or exculpation from costs, expenses or other liabilities or (ii) changes in the organizational control or ownership of any party, which agreement (in the case of clause (i) or clause (ii)) is contrary to public policy or Applicable Law.

(b) Jurisdiction, Venue, etc. The enforceability of any agreement to submit to the jurisdiction of any specific federal or state court (other than the enforceability in a court of the State of New York of any such agreement to submit to the jurisdiction of a court of the State of New York), to waive any objection to the laying of the venue, to waive the defense of forum non conveniens in any action or proceeding referred to therein, to waive trial by jury, to effect service of process in any particular manner or to establish evidentiary standards, and any agreement regarding the choice of law governing any Subject Document (other than the enforceability in a court of the State of New York or in a federal court sitting in the State of New York and applying New York law to any such agreement that the laws of the State of New York shall govern).

(c) Remedies. The enforceability of any provision in any Subject Document to the effect that rights or remedies are not exclusive, that every right or remedy is cumulative and may be exercised in addition to any other right or remedy, that the election of some particular remedy does not preclude recourse to one or more others or that failure to exercise or delay in exercising rights or remedies will not operate as a waiver of any such right or remedy.

Qualifications and Limitations Applicable to Our Opinions

The opinions set forth above are subject to the following qualifications and limitations:

(a) Applicable Law. Our opinions are limited to the Applicable Law, and we do not express any opinion concerning any other law.

(b) Bankruptcy. Our opinions are subject to the effect of any applicable bankruptcy, insolvency (including, without limitation, laws relating to preferences, fraudulent transfers and equitable subordination), reorganization, moratorium and other similar laws affecting creditors’ rights generally.

(c) Equitable Principles. Our opinions are subject to the effect of general principles of equity (regardless of whether considered in a proceeding in equity or at law), including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing. In applying such principles, a court, among other things, might limit the availability of specific equitable remedies (such as injunctive relief and the remedy of specific performance), might not allow a creditor to accelerate maturity of debt or exercise other remedies upon the occurrence of a default deemed immaterial or for non-credit reasons or might decline to order a debtor to perform covenants in a Subject Document.

(d) Unenforceability of Certain Provisions. Provisions contained in the Notes or the Subject Documents which require waivers or amendments to be made only in writing may be unenforceable or ineffective, in whole or in part. The inclusion of such provisions, however, does not render any of the Notes or the Subject Documents invalid as a whole.

(e) Choice of New York Law and Forum.

Exhibit 8.1

May 16, 2024

NiSource Inc.

801 East 86th Avenue

Merrillville, Indiana 46410

Ladies and Gentlemen:

We have acted as United States federal income tax counsel for NiSource Inc. (the “Company”) in connection with (i) the Registration Statement on Form S-3 (File No. 333-268084) (the “Registration Statement”), which was filed by the Company with the Securities and Exchange Commission (the “SEC”) in connection with the registration under the Securities Act of 1933, as amended (the “Act”), of certain securities of the Company, including debt securities, and (ii) the issuance by the Company of 6.950% Fixed-to-Fixed Reset Rate Junior Subordinated Notes due in 2054 (the “Junior Subordinated Notes”), as described in the Company’s Prospectus, dated November 1, 2022 (the “Prospectus”) and Prospectus Supplement, dated May 13, 2024 (the “Prospectus Supplement”). The Registration Statement became effective on November 1, 2022. This opinion letter is being furnished in accordance with the requirements of Item 16 of Form S-3 and Item 601(b)(5)(i) of Regulation S-K promulgated under the Act.

In rendering our opinion, we have examined originals or copies, certified or otherwise identified to our satisfaction, of (i) the Registration Statement, (ii) the Prospectus, (iii) the Prospectus Supplement, (iv) the Indenture as defined in the terms agreement relating to the offer and sale of the Junior Subordinated Notes (the “Terms Agreement”), (v) the Terms Agreement, and (vi) such other agreements and documents as we have deemed relevant and necessary, and we have made such investigations of law as we have deemed appropriate as a basis for the opinion expressed below.

In our examination, we have assumed, with your permission, (i) the authenticity of original documents, (ii) the accuracy of copies and the genuineness of signatures, (iii) that the execution and delivery by each party to a document and the performance by such party of its obligations thereunder have been authorized by all necessary measures and do not violate or result in a breach of or default under such party’s certificate or instrument of formation and by-laws or the laws of such party’s jurisdiction of organization, (iv) that each agreement represents the entire agreement between the parties with respect to the subject matter thereof, (v) that the parties to each agreement have complied, and will comply, with all of their respective covenants, agreements and undertakings contained therein, (vi) that the transactions provided for by each agreement were and will be carried out in accordance with their terms, (vii) that the factual representations made to us by the Company in its officer’s certificate dated as of the date hereof and delivered to us for purposes of this opinion (the “Officer’s Certificate”) are true, correct and complete and will be true, correct and complete at the time of closing of the offering and delivery of the Junior Subordinated Notes (as if made as of such time), and (viii) that any factual representations made in the Prospectus, the Prospectus Supplement or the Officer’s Certificate “to the best knowledge of,” “in the belief of,” or similarly qualified are true, correct and complete without such qualification. If any of the above described assumptions are untrue for any reason or if the issuance of the Junior Subordinated Notes is consummated in a manner that is inconsistent with the manner in which it is described in the Prospectus Supplement, our opinion as expressed below may be adversely affected and may not be relied upon.

In rendering our opinion, with your permission, we have not undertaken any independent investigation or verification of any fact or matter set forth in any document or materials or any assumption upon which we have relied (including, without limitation, any statement or representation contained in the Officer’s Certificate), and we expressly disclaim any intent, undertaking, or obligation to make any such investigation or verification.

The opinion set forth below is based upon the Internal Revenue Code of 1986, as amended, Treasury Regulations (including temporary and proposed Treasury Regulations) issued thereunder, Internal Revenue Service (“IRS”) rulings and pronouncements and judicial decisions now in effect, all of which are subject to change, possibly with retroactive effect. Our opinion is limited to the matters expressly stated herein. Our opinion is rendered only as of the date hereof, and its validity could be affected by subsequent changes in applicable law. We disclaim any undertaking to advise you or any other person with respect to any such change subsequent to the date hereof. An opinion of counsel with respect to an issue represents counsel’s best judgment as to the outcome on the merits with respect to such issue and is not binding on the IRS or the courts. Thus, there can be no assurance or guarantee that the IRS will not assert a contrary position with respect to an issue or any conclusions contained herein, or that a court will not sustain such a position if asserted by the IRS.

Based upon and subject to the foregoing, the discussion contained in the Prospectus Supplement under the caption “Material U.S. Federal Income Tax Considerations,” insofar as such discussion relates to legal conclusions with respect to matters of United States federal income tax law, represents our opinion and, subject to the qualifications, exceptions and limitations stated therein and herein, such discussion is accurate in all material respects. Such discussion does not, however, purport to discuss all United States federal income tax consequences to holders of the Junior Subordinated Notes and is limited to those United States federal income tax consequences to holders of the Junior Subordinated Notes specifically discussed therein and subject to the qualifications set forth therein and herein.

We are rendering this opinion to you solely in connection with the offering of the Junior Subordinated Notes, and this opinion may not be relied upon by any other person or for any other purpose without our prior written consent. We hereby consent to use of this opinion as an exhibit to the Company’s Current Report on Form 8-K regarding the issuance and sale of the Junior Subordinated Notes and the incorporation of this opinion by reference in the Registration Statement and to references to us under the heading “Legal Matters” in the Registration Statement and in the Prospectus Supplement relating to the Junior Subordinated Notes. In giving this consent, we do not thereby admit that we come within the category of persons whose consent is required by the Act or the rules and regulations promulgated thereunder.
