Without prejudice to such general powers, but subject to the same limitations, the Board shall be empowered to conduct, manage and control the business and affairs of the Company and to make such rules and regulations therefor not inconsistent with applicable Law or this Agreement, as the Board shall deem to be in the best interest of the Company. Each Director is hereby designated as a “manager” of the Company within the meaning of Section 18-101 of the Act.

Section 1.2Number of Directors; Proportional Appointment Rights.

(a)The authorized number of Directors constituting the Board shall be seven (7) Directors (the “Total Number of Directors”).

(b)The BIP Investor Member shall, as of the Effective Date, be entitled to appoint two Directors, and the BIP Investor Member shall retain the right to appoint at least two Directors for so long as the Investor Members collectively hold at least a 17.5% Percentage Interest in the aggregate. In the event that the Investor Members’ aggregate Percentage Interest is reduced below 17.5% but remains at or above a 9.9% Percentage Interest, the BIP Investor Member shall retain the right to appoint one Director. In the event that the Investor Members’ aggregate Percentage Interest is reduced below 9.9%, the BIP Investor Member shall cease to be entitled to appoint a Director. Any Directors appointed by the BIP Investor Member are referred to herein as “Investor Directors”. The appointment of any particular proposed Investor Director shall be subject to the NiSource Member’s prior written consent of the identity of such individual prior to his or her appointment to the Board; provided however, that the NiSource Member shall not have any consent right over the appointment of a proposed Investor Director that is a Qualified Designee.

(c)In the event that the Investor Members’ aggregate Percentage Interest decreases below 17.5% or 9.9%, as applicable, if the BIP Investor Member fails to remove an Investor Director concurrently with such decrease in the Investor Members’ aggregate Percentage Interest to be in compliance with the BIP Investor Member’s Director appointment rights set forth in Section 2.2(b), then the NiSource Member may remove such appropriate number of Investor Directors from the Board such that the BIP Investor Member is in compliance with its Director appointment rights set forth in Section 2.2(b), such removal being effective immediately.

(d)The NiSource Member shall be entitled to appoint all of the remaining Total Number of Directors that the Investor Member is not entitled to appoint pursuant to Section 2.2(b). Directors appointed by the NiSource Member are referred to herein as “NiSource Directors”; provided, that any NiSource Director must be a Qualified Designee. The NiSource Member shall further be entitled to designate a NiSource Director to serve as the chairperson of the Board.

(e)For so long as the BIP Investor Member is entitled to appoint an Investor Director, the BIP Investor Member shall be further entitled to designate the Board Observer or any other individual (provided, that such designee is a Qualified Designee) (the “Designated Alternate”) in its place and stead in the event that the Investor Director is unable to attend such meeting (or meetings of Board committees, if any pursuant to Section 2.12). The Designated Alternate will be entitled to exercise the powers of the Investor Director at such meetings, and will be subject to all of the responsibilities of an Investor Director hereunder at such meeting as if they were an Investor Director. The appointment of such Designated Alternate shall be subject to the same approval right of the NiSource Member applicable to the Investor Director under Section 2.2(b). If the Designated Alternate is serving in lieu of the Investor Director at

any Board or committee meeting, the BIP Investor Member shall provide written notice to the NiSource Member of this fact prior to the commencement of such meeting (which notice may be by way of an email to the NiSource Directors), and such notice shall be recorded in the minutes of such meeting. For the avoidance of doubt, any references to approval or notice by the Investor Director in this Agreement will be deemed to refer to the Investor Director, and not the Designated Alternate, except in respect of the voting on matters presented at the meeting at which the Designated Alternate is attending. In the event that the Designated Alternate is also a Board Observer, at any Board or committee meeting in which he or she is serving as the Investor Director pursuant to this Section 2.2(e), he or she shall be deemed to be serving only as an Investor Director and not as a Board Observer at such meeting.

Section 1.3Removal of Directors

. Any one or more Directors may be removed at any time, with or without cause, by the Member that appointed such Director, and except as provided in Section 2.2(c), may not be removed by any other means. If a Director is convicted by a court or equivalent tribunal of any felony (or equivalent crime in the applicable jurisdiction), or of any misdemeanor (or equivalent crime in the applicable jurisdiction) that involves financial dishonesty or moral turpitude, then the Member that appointed such Director shall, unless consented to by the NiSource Member in the case of an Investor Director and by the BIP Investor Member in the case of a NiSource Director, promptly remove such Director. Delivery of a written notice to the Company by a Member designating for removal of a Director appointed by such Member shall conclusively and with immediate effect constitute the removal of such Director, without the necessity of further action by the Company, the Board, or by the applicable removed Director. Each Director duly appointed by a Member pursuant to and in accordance with the provisions of Section 2.2 shall hold office until his or her resignation, death, permanent disability, removal pursuant to and in accordance with Section 2.2 or with this Section 2.3, or until a successor Director is duly appointed by the Member that appointed (and continues to be entitled to appoint) such Director.

Section 1.4Vacancies

. A vacancy shall be deemed to exist in case of the resignation, death, permanent disability or removal of any Director. The Member entitled to appoint a Director to the vacant directorship may appoint or elect a Director thereto to take office (a) immediately, (b) effective upon the departure of the vacating Director, in the case of a resignation, or (c) at such other later time as may be determined by such Member.

Section 1.5Acts of the Board; Voting

. Except as otherwise expressly set forth in this Agreement (including Section 8.1), a vote of a majority of the Directors present at a duly called and noticed meeting of the Board at which a quorum is present shall be required to authorize or approve any action of the Board. Every act of or decision taken or made by the Directors pursuant to the vote required by this Section 2.5 shall be conclusively regarded as an act of the Board.

Section 1.6Compensation of Directors. The Board shall have the authority to fix the compensation of Directors for their service to the Company, if any. The Board shall reimburse the Directors for their respective reasonable, documented out-of-pocket expenses incurred for attendance at meetings of the Board consistent with the Company’s then-applicable policies related to travel and expenses for directors or executive officers (or, if none exists, such travel and expense policies of Parent). Nothing herein shall be construed to preclude any Director from serving the Company or any of its Affiliates in any other capacity and receiving compensation therefor.

Section 1.7Meetings of Directors; Notice

. Except as provided pursuant to Section 2.10, meetings of the Board, both regular and special, for any purpose or purposes may be called at any time by the Board or by the Company at the request of any Director, by providing at least seven calendar days’ written notice to each Director unless the chairperson of the Board determines, acting reasonably, that there is a significant and time sensitive matter that requires shorter notice to be given, in which case a meeting of the Board may be called by

giving at least 48 hours’ written notice to each Director. Regular Board meetings will be held quarterly. Each notice shall state the purpose(s) of and agenda for the meeting and include all required information, including dial-in numbers or other applicable access information, in order to participate in the meeting by telephonic means, over the internet or by means of any other customary electronic communications equipment. Unless otherwise agreed by unanimous consent of the Board, no proposal shall be put to a vote of the Board unless it has been listed on the agenda for such meeting. Notice of the time and place of meetings shall be delivered personally or by telephone to each Director, or sent by e-mail or other electronic communication to any Director. Any notice given personally or by telephone shall be communicated to the applicable Director. A Director may waive the notice requirement set forth in this Section 2.7 by any means reasonable in the circumstances, including by communication to one or more other Directors, and the presence of a Director at a meeting or the approval by a Director of the minutes thereof shall conclusively constitute a waiver by such Director of such notice requirement.

Section 1.8Quorum.

(a)Except as otherwise expressly set forth herein, the presence (whether physical, telephonic, over the internet or by means of other customary electronic communications equipment) of a majority of the number of Directors then serving on the Board (without regard to the Total Number of Directors), including at least one Investor Director, at a meeting of the Board shall constitute a quorum of the Board for the transaction of all business thereat; provided, that if quorum fails at two (2) consecutive attempted meetings that are called pertaining to the same subject matter with proper notice due to the failure of the Investor Director(s) to attend, then at the third attempted meeting only a majority of the number of Directors then serving on the Board (without regard to the Total Number of Directors or the attendance of the Investor Director(s)) must be present in person, by telephone or other electronic means or by proxy in order to constitute a quorum for the transaction of business for purposes of conducting only those matters that were included on the agenda for the attempted meetings immediately preceding such third attempted meeting; provided, that, at least twenty-four (24) hours prior written notice of any rescheduled meeting is required to be provided to the other Directors.

(b)If a quorum is not present at any meeting of the Board, the Directors present at such meeting may adjourn the meeting, without notice other than announcement at the meeting.

Section 1.9Place and Method of Meetings.

(a)Meetings of the Board may be held at any place, whether within or outside the State of Delaware or the State of Indiana, and meetings may be held, in whole or in part, by telephonic means, over the internet or by means of any other customary electronic communications equipment.

(b)The Directors may participate in meetings of the Board by telephonic means, over the internet or by means of any other customary electronic communications equipment, and, to the fullest extent permitted by applicable Law, shall be deemed to be present at such meeting for all purposes, including for purposes of determining quorum and of voting.

Section 1.10Action by the Board Without a Meeting

. Any action required or permitted to be taken by the Board may be taken without a meeting if a number of Directors the vote of whom would be minimally necessary to approve such action at a meeting of the Board shall individually or collectively consent in writing to such action; provided, that in order for such consent to be effective it shall have been provided to all Directors at least forty-eight (48) hours prior to its stated effectiveness, unless such prior notice is waived in writing by the Directors taking any such written action which includes at least one (1) Investor Director. Notwithstanding the foregoing, no action set forth in Section 8.1 that requires the consent of the BIP Investor Member shall be effected by written action entered into pursuant to this Section 2.10 without the BIP Investor Member’s written consent. Any written actions of the Board may be in counterparts and transmitted by e-mail and shall be filed with the minutes of the proceedings of the Board. Such written actions shall have the same force and effect as a vote of the Board.

Section 1.11Duties of Directors. Other than as set forth in Section 9.3, each member of the Board shall have fiduciary duties identical to those of directors of a business corporation organized under the General Corporation Law of the State of Delaware and except to the extent not permitted by applicable Law, no member of the Board shall be personally liable to the Company or its Members for monetary damages for breach of its fiduciary duties in such capacity. The provisions of this Agreement, to the extent that they expand or restrict the duties and liabilities of the Board, otherwise existing at law or in equity, are agreed by the Members to replace such other duties and liabilities of the Board.

Section 1.12Committees. The Board may create one or more committees of the Board, delegate responsibilities, duties and powers to such one or more committees, and appoint Directors to serve thereon. Each Director appointed to serve on any such committee shall serve at the pleasure of the Board, or otherwise in accordance with the terms of the resolution designating the applicable committee. Section 2.4, Section 2.7, Section 2.8, Section 2.9 and Section 2.10 shall each apply to any committee of the Board with the same terms applicable to the Board, mutatis mutandis. For each committee of the Board, the Board shall designate one Investor Director to serve on each such committee so long as the BIP Investor Member is entitled to appoint a Director pursuant to Section 2.2.

Section 1.13Investor Member Board Observer

. The BIP Investor Member shall be entitled to appoint one Person (which shall be an individual) to serve as an observer of the Board (the “Board Observer”) for so long as (i) the BIP Investor Member is entitled to appoint only one (1) Investor Director, but in no event when the BIP Investor Member is entitled to appoint two (2) Investor Directors or (ii) the Investor Members’ aggregate Percentage Interest is greater than or equal to 4.9% but in no event if the BIP Investor Member is entitled to appoint two (2) Directors, the identity of whom shall be subject to the prior written consent of the NiSource Member. The Board Observer shall have the right to receive notice of, attend and participate in all meetings of the Board (and any committee thereof) and to receive all information provided to Directors at the same time and in the same manner as provided to such Directors; provided, however, that the Company and the Board will be entitled to withhold access to any portion of the information and to exclude the Board Observer from any portion of any meeting of the Board (or any committee thereof) if the Company or the Board determines in good faith in reliance upon the advice of counsel that access to such information or attendance at such meeting (i) is reasonably necessary to preserve an attorney-client privilege of the Company or the Board or (ii) otherwise implicates any conflict of interest between any Investor Member, on the one hand, and a particular matter or transaction under consideration by the Board, on the other hand; provided, however, that the BIP Investor Member shall be notified of any intent to exclude the Board Observer in reliance on clause (ii) above in advance of any meeting from which the Board Observer is to be excluded to the extent reasonably practicable; provided, further, that, any Board Observer that is excluded shall only be excluded for such portion of the meeting during which such conflicted matter or transaction is being discussed. For the avoidance of doubt, the Board Observer shall not have any voting rights with respect to any matter brought before the Board and shall not be counted in any manner with respect to whether a quorum is present at a meeting of the Board, and (without limiting the Company’s obligations to provide the Board Observer with notice of meetings of the Board and any committee thereof as set forth in this Section 2.13) no defect in the provision of notice to the Board Observer of any meeting of the Board shall be construed to constitute a defect in the provision of notice to Directors. The Board Observer shall be bound by the same confidentiality obligations as the Directors as set forth in Section 9.6. The BIP Investor Member may cause the Board Observer to resign or appoint a replacement Board Observer from time to time by giving written notice to the Company. In the event that the Investor Members’ aggregate Percentage Interest becomes less than 4.9%, the BIP Investor Member’s rights under this Section 2.13 shall immediately cease. For the avoidance of doubt, the sole purpose of this Section 2.13 is to provide observation rights (subject to the limitations and conditions set forth in this Section 2.13) to an individual Representative of the BIP Investor Member, and in no event will any Board Observer be construed to be a third-party beneficiary of this Agreement, an agent of the Company of any kind or for any purpose, or have any other claim against the Company or the Members in relation to any matter whatsoever.

Section 1.14Related Party Matters.

(a)The Parties acknowledge that certain Affiliates of the Company provide various services to the Company and its Subsidiaries and that all of such services shall continue in the ordinary course of business. All agreements between any member of the Outside Group, on the one hand, and the Company Group, on the other hand, (such transactions, “Affiliate Agreements”), shall be (i) entered into and carried out in a manner that, except as may be required by any applicable Law or Order, is (A) consistent with past practices and the corporate allocation and affiliate transaction policies of the Outside Group in effect at such time and (B) on terms and conditions that are pursuant to the corporate allocation policies and affiliate transaction policies of the Outside Group as of such time to the extent that they are non-discriminatory against the Company and its Subsidiaries and are generally consistent with the corporate allocation policies and affiliate transaction policies of the Outside Group, (ii) entered into and carried out in accordance with the requirements of any applicable Law or Order (including, for the avoidance of doubt, on such terms and conditions as may be required to obtain the approval of the applicable Governmental Body in respect of such transaction) and (iii) if applicable pursuant to Section 8.1, approved by the Board. Notwithstanding anything to the contrary in this Agreement, except as required by applicable Law, the NiSource Member shall ensure during the term of this Agreement that any methodologies used to allocate costs to the Company Group (i) are and will be consistently applied to other members of the Outside Group in a manner that does not have a disproportionate adverse impact on the Company or any of its Subsidiaries as compared to any member of the Outside Group and (ii) would not result in any fines or penalties that are imposed on any member of the Outside Group being allocated to the Company or any of its Subsidiaries. The NiSource Member shall also use commercially reasonable efforts to ensure corporate separateness from the NiSource Member and the other members of the Outside Group in a manner and consistent with the Company Group’s and the Outside Group’s respective past practices and applicable Law and Orders. The NiSource Member shall continue to audit its corporate services annually by its then current auditor in the ordinary course and shall share such audit with the BIP Investor Member (including any work papers and other supporting documentation reasonably requested by the BIP Investor Member (subject to its prior execution of a customary non-reliance letter agreement to the extent requested by such auditor)).

(b)Each of the Investor Members acknowledges and agrees that (i) the Company Group and the Outside Group has prior to the Effective Date engaged in Affiliate Agreements, and will, pursuant to and in accordance with the provisions of Section 2.14(a), from and after the Effective Date engage in new Affiliate Agreements, subject to the BIP Investor Member’s approval rights under Section 8.1 (if applicable) and (ii) all services provided by any member of the Outside Group to any member of the Company Group as of the Effective Date and (iii) the promissory notes held or payable by the Company’s Subsidiary, Northern Indiana Public Service Company LLC (“NIPSCO”), payable to NiSource Development Company, Inc. (the “NiSource Notes”) shall or will remain outstanding and be payable in accordance with their terms or sooner as the Board determines in good faith is appropriate.

(c)In the event the Company and/or the NiSource Member becomes aware of any material breach or material default (it being understood that, for purposes of this clause (c), a breach or default will be deemed to be “material” if the reasonably expected amount of damages that would be sustained by the Company and its Affiliates as a result of such breach or default, or series of related breaches or defaults, would exceed $30,000,000 in the aggregate, subject to an annual increase by the CPI Escalator) by any member of the Company Group or Outside Group under any Affiliate Agreement (an “Affiliate Agreement Default”), the Company and/or the NiSource Member, as applicable, shall promptly, but in any event within ten (10) Business Days after becoming aware of such Affiliate Agreement Default, send a written notice (an “Affiliate Agreement Default Notice”) to the Company and the BIP Investor Member setting forth in reasonable detail the nature of such Affiliate Agreement Default and the reasonable estimate of the current and future anticipated losses associated with such Affiliate Transaction Default (to the extent feasible to make a reasonable estimate at such time). After delivery of such Affiliate Agreement Default Notice to the BIP Investor Member, the Company (and, if the Company did not provide the Affiliate Agreement Default Notice, the NiSource Member) shall promptly provide the BIP Investor Member with any additional information reasonably requested by the BIP Investor Member and available to the NiSource Member relating to such Affiliate Agreement Default. The defaulting party under such Affiliate Agreement shall have (i) twenty (20) Business Days following the expiration of the applicable cure period in respect of such Affiliate Agreement, to fully cure any monetary Affiliate Agreement Default, and (ii) sixty (60) days following the expiration of the applicable cure period in respect of such Affiliate Agreement, to fully cure any non-monetary Affiliate Agreement Default, subject

to and consistent with applicable Law and Orders, if capable of being cured. In the event that any material alleged Affiliate Agreement Default is not timely cured in accordance with the preceding sentence, the BIP Investor Member shall have the sole right to cause the Company and its Subsidiaries to take, or refrain from taking, any actions in connection with the enforcement of or compliance with the rights or obligations of the Company or any of its Subsidiaries under the terms of the applicable Affiliate Agreement. In addition to, and not in limitation of, the foregoing provisions of this Section 2.14(c), the Company shall notify the BIP Investor Member prior to, or within ten (10) days following, its execution of any new Affiliate Agreement or any material amendment to any Affiliate Agreement setting forth in reasonable detail the nature of such new Affiliate Agreement or such amendment and, upon request from the BIP Investor Member, shall provide copies of all Contracts relating to such new Affiliate Agreement or such amendment within five (5) Business Days of such request.

The treasurer, if one is designated, shall have custody of the Company’s funds and securities and shall keep full and accurate accounts and records of receipts, disbursements and other transactions in books belonging to the Company, and shall deposit all moneys and other valuable effects in the name and to the credit of the Company in such depositories as may be designated from time to time by the Board. The treasurer shall disburse the funds of the Company as may be ordered by the Board, taking proper vouchers for such disbursements, and shall render the president and the Board, when so directed, an account of all of his or her transactions as treasurer and of the financial condition of the Company. The treasurer shall perform such other duties and have such other powers as the Board may from time to time prescribe. If required by the Board, the treasurer shall give the Company a bond of such type, character and amount as the Board may require. The assistant treasurers, if any are designated, unless otherwise determined by the Board, shall, in the absence or disability of the treasurer, perform the duties and exercise the powers of the treasurer. They shall perform such other duties and have such other powers as the Board may from time to time prescribe.

Section 1.7Duties of Officers. Other than as set forth in Section 9.3 with respect to any Representative of Parent or its Affiliates who is also an officer of the Company, each officer of the Company (in such individual’s capacity as an officer) will owe the Company, its Subsidiaries and the Members such fiduciary duties that apply to officers of a Delaware corporation. No provision of this Agreement will be deemed to limit or eliminate such fiduciary duties.

Section 1.1Events of Default

. The following shall constitute events of default (each, an “Event of Default”) by the applicable Member under this Agreement:

(a)any material breach of this Agreement by such Member;

(b)any failure by such Member to make any Mandatory Capital Contribution pursuant to and in accordance with a Capital Request Notice issued pursuant to Section 5.1 or, with respect to an Additional Funding Requirement (other than a Mandatory Capital Contribution), a duly authorized officer of each of the Investor Members has affirmed in writing that such Investor Member would make such Additional Funding Requirement in its Response to Capital Call but failed to do so within the time period set forth in Section 5.1, in any case any such failure to fund by any Investor Member shall be deemed to be a failure to fund by all of the Investor Members;

(c)any purported Transfer by such Member made other than pursuant to and in accordance with the terms and conditions of this Agreement; and

(d)the filing of a petition seeking relief, or the consent to the entry of a decree or Order for relief in an involuntary case, under the bankruptcy, rearrangement, reorganization or other debtor relief Laws of the United States or any state or any other competent jurisdiction or a general assignment for the benefit of its creditors by such Member or by any of its controlling Affiliates.

Section 1.2Default Notice

. If an Event of Default occurs, then any Member (other than the Defaulting Member) may deliver to the Company and to the Member subject to the Event of Default (the “Defaulting Member”; provided, that at any time the Defaulting Member is an Investor Member, then both Investor Members shall be deemed Defaulting Members until such Investor Member ceases to be a Defaulting Member according to the terms of this Agreement) a notice of the occurrence of such Event of Default, setting forth the circumstances of such Event of Default. If, within thirty (30) days following the delivery of such notice (or, with respect to an Event of Default set forth in Section 4.1(b), ten (10) days), the Defaulting Member has not cured the event giving rise to the Event of Default (if capable of being so

cured), the provisions of this Agreement applicable to a “Defaulting Member” shall apply to such Defaulting Member and, in addition to any other rights and remedies provided under this Agreement, (i) if the Defaulting Member is an Investor Member, the Defaulting Member’s voting rights, including its approval rights in Section 8.1, shall be suspended and (ii) any net Available Cash required to be distributed to the Defaulting Member shall instead be distributed to the non-Defaulting Members, or the Company, as applicable, if such breach is capable of being cured by the payment of such amounts which such clauses (i) and (ii) shall apply as applicable (and such Member shall be considered a “Defaulting Member”) until the applicable Event of Default and the material effects thereof have been cured (if capable of being so cured).

Section 1.3Dissolution.

(a)Subject to obtaining the requisite authorization, approval or consent of any Governmental Body, the Company shall dissolve, and its affairs shall be wound up, upon either (i) the approval by the Board and the written consent of all of the Members or (ii) the entry of a decree of judicial dissolution under Section 18-802 of the Act (each, an “Event of Dissolution”).

(b)Upon the occurrence of an Event of Dissolution, the Company will continue solely for the purposes of winding up its affairs in an orderly manner, liquidating its assets and satisfying the claims of its creditors and the Members. No Member, acting in its capacity as such, will take any action that is inconsistent with, or not necessary to or appropriate for, the winding up of the Company’s business and affairs. All covenants contained and obligations provided for in this Agreement will continue to be fully binding upon the Members until such time as the property of the Company has been distributed pursuant to Section 5.3 and the certificate of formation of the Company has been canceled pursuant to the Act.

(c)After the occurrence of an Event of Dissolution, and after all of the Company’s debts, liabilities and obligations have been paid and discharged or adequate reserves have been made therefor and all of the remaining assets of the Company have been distributed to the Members, the Company shall make necessary resolutions and filings to dissolve the Company under the Act.

Section 1.1Capital Contributions.

(a)If the Board determines that it is in the best interests of the Company to obtain additional equity capital for purposes of (i) developing, acquiring or maintaining Qualifying Core Assets or funding ordinary course operations of the Company Business, (ii) satisfying the Company’s obligations to Third Parties (including in respect of the Indebtedness of the Company Group or under any Contract), (iii) complying with applicable Law or Order, or (iv) funding any Emergency Expenditures (any such determination by the Board an “Additional Funding Requirement”), then the Board may direct the Company to submit to the Members a written capital funding request notice (a “Capital Request Notice”), which Capital Request Notice shall set forth (A) the anticipated amount of, and the reason for, such Additional Funding Requirement, (B) each Member’s requested share of such Additional Funding Requirement, which with respect to each Member shall equal such Member’s Percentage Interest multiplied by the aggregate amount of the Additional Funding Requirement (such share, the “Pro Rata Request Amount”) and (C) the funding date for such Additional Funding Requirement (the “Capital Request Funding Date”), which Capital Request Funding Date shall not be earlier than forty-five (45) days following the date on which such Capital Request Notice is delivered to the Members except for any Capital Request Notices pertaining to Emergency Expenditures in which case the Capital Request Funding Date shall not be earlier than ten (10) Business Days. Any Additional Funding Requirements for the period from the Investment Closing Date and including the date that is three (3) years from the Investment Closing Date and which do not exceed the Maximum Investor Commitment shall be a “Mandatory Capital Contribution”. Any Additional Funding Requirement shall require each Member to contribute its Pro Rata Request Amount; provided, that any obligations of the Investor Members under this Section 5.1(a) to contribute their respective Pro Rata Request Amounts shall be joint and several. Requests for additional equity capital other than pursuant to a Mandatory Capital Contribution shall be determined by the Board and each Member may, but shall not be obligated to, contribute its Pro Rata

Request Amount as called for in the applicable Capital Request Notices; provided, that in the event the BIP Investor Member elects to contribute its Pro Rata Request Amount as called for in the applicable Capital Request Notice and the VCOC Investor Member elects not to contribute its Pro Rata Request Amount, then the BIP Investor Member shall be required to fund the total Pro Rata Request Amount for the Investor Members, including such Pro Rata Request Amount allocated to the VCOC Investor Member. For the avoidance of doubt, other than (i) a Mandatory Capital Contribution pursuant to this Section 5.1, (ii) the joint and several obligations of the Investor Members to contribute their respective Pro Rata Request Amounts as set forth in this Section 5.1 and (iii) any obligation of the BIP Investor Member to fund on any Pro Rata Request Amount allocated to the VCOC Investor Member pursuant to the immediately the preceding sentence, no Member shall have any obligation to fund any such requests for additional equity capital unless such Member indicates it will do so in accordance with this Section 5.1. Upon the receipt of a Capital Request Notice, each Member shall, within twenty (20) days of such receipt, provide written notice to the Company and the other Members as to the extent to which such Member intends to fund its Pro Rata Request Amount, whether in whole, in part or not at all (a “Response To Capital Call”). If one Member indicates in its Response To Capital Call that it does not intend to fund its Pro Rata Request Amount in full, and any other Member had, prior thereto, submitted a Response To Capital Call indicating that it intends to fund a greater percentage than any such other Member of its Pro Rata Request Amount, then any such other Member will be entitled to amend its Response To Capital Call to reduce its percentage funding to an amount representing a percentage of its Pro Rata Request Amount not less than the lower percentage indicated in the other Member’s Response to Capital Call; provided, that no Investor Member shall be entitled to reduce its percentage funding pursuant to this sentence if the Member that indicated its intent not to fund its Pro Rata Request Amount in full is an Investor Member. If no Response to Capital Call is received within such twenty (20) days, the Member shall be deemed to have elected to not fund.

(b)If any Member refuses or fails to make all or any portion of its Pro Rata Request Amount pursuant to this Section 5.1 on or prior to the applicable Capital Request Funding Date (such Member, the “Non-Contributing Member”, and the unfunded amount, the “Unfunded Amount”), then the Company shall provide written notice thereof to the other Member(s) (the “Contribution Unfunded Amount Notice”); provided, that if the Non-Contributing Member is an Investor Member, the Investor Members jointly shall be deemed the Non-Contributing Member and all references in this Section 5.1(b) to the Pro Rata Request Amount of the Non-Contributing Member shall refer to the aggregate Pro Rata Request Amount of both Investor Members combined, and:

(i)Excess Contribution. To the extent that the Non-Contributing Member contributes a portion (but less than all) of its Pro Rata Request Amount, and any other Member who is not a Non-Contributing Member (an “Over-Contributing Member”) has contributed a greater percentage of its Pro Rata Request Amount than the Non-Contributing Member, such Over-Contributing Member shall have the right to elect (which election shall be made by written notice to the Company and the other Members no later than 10 Business Days following the date of the Contribution Unfunded Amount Notice and any may consist of any combination thereof) to (A) receive a special distribution of the amount of such excess (the “Excess Contribution”), such that the Excess Contribution is returned to such Over-Contributing Member (and the Company shall cause such special distribution to be made as promptly as practicable), (B) have the portion of such Excess Contribution that would have been the Non-Contributing Member’s share thereof treated as a loan to the Company (consistent with the methodology in clause (ii)(A), below), or (C) except in the event that the Non-Contributing Member is the NiSource Member, have the portion of such Excess Contribution that would have been the Non-Contributing Member’s share thereof treated as a contribution to capital (consistent with the methodology in clause (ii)(B) below).

(ii)Top-Up Right. A Member that has paid its full Pro Rata Request Amount (the “Contributing Member”; provided, that no Investor Member may be a Contributing Member if the other Investor Member has not paid its full Pro Rata Request Amount unless an Investor Member has funded the full Pro Rata Request Amount of any other Investor Member on behalf of such Investor Member) shall have the right (but not the obligation) to elect (which election shall be made by written notice to the Company and the other Members no later than ten (10) Business Days following the receipt of the Contribution Unfunded Amount Notice) to contribute any portion of the Unfunded Amount in accordance with this Section 5.1(b) either (A) as a loan to the Company, or (B) except in the event that the Non-

Contributing Member is the NiSource Member, as a capital contribution to the Company (or as any combination thereof as the Contributing Member elects) in accordance with the following procedures:

(A)Loan. The Contributing Member may elect to advance all or a portion of the Unfunded Amount to the Company on behalf of the Non-Contributing Member, which advance shall be treated as a loan by the Contributing Member to the Company (an “Unfunded Amount Loan”) at an interest rate equal to a floating rate equal to the Wall Street Journal Prime Rate plus 0.75% per annum. Subject to the terms of this Agreement, each Unfunded Amount Loan shall be repaid out of any subsequent distributions made pursuant to Section 5.2 to which the Non-Contributing Member would otherwise be entitled under this Agreement, and such payments shall be applied first to the payment of accrued but unpaid interest on each such Unfunded Amount Loan and then to the payment of the outstanding principal, until such Unfunded Amount Loan is paid in full.

(B)Capital Contribution. Except in the event that the Non-Contributing Member is the NiSource Member, the Contributing Member may elect to contribute an amount equal to all or a portion of the Unfunded Amount to the Company. If the Contributing Member elects to contribute to the Company all or a portion of the Unfunded Amount, then, on or after the earlier of the date that the Non-Contributing Member indicates it will not cure the failure to fund its full Pro Rata Request Amount and the thirtieth (30th) day following the date of the Contribution Unfunded Amount Notice, the Company shall issue to the Contributing Member the amount of additional Membership Interests that can be purchased for such funded amount at a price per Membership Interest equal to 90% of the Fair Market Value of the Company (measured as of the date that such contribution is to be made) per Membership Interest until the NiSource Member has purchased up to $250,000,000 of additional Membership Interests pursuant hereto, and thereafter at Fair Market Value of the Company, and the Contributing Member’s and the Non-Contributing Member’s respective Percentage Interests will be adjusted accordingly. For the avoidance of doubt, this subsection shall in all respects not be subject to the rights and procedures set forth in Section 7.1.

(C)Cure Right. Notwithstanding anything to the contrary in this Section 5.1, on or before the thirtieth (30th) day following the date of the Contribution Unfunded Amount Notice, a Non-Contributing Member may make a contribution to the Company equal to the sum of the Unfunded Amount plus, if the Contributing Member already made an Unfunded Amount Loan in respect of such Unfunded Amount, any interest accrued on the Unfunded Amount Loan, following which (1) the Unfunded Amount advanced by the Contributing Member to the Company together with any such interest shall be paid to the Contributing Member, and (2) the former Non-Contributing Member shall be deemed to have cured its failure to pay the Pro Rata Request Amount prior to the Capital Request Funding Date with respect to the applicable Capital Request Notice.

For the avoidance of doubt, the remedies set forth in this Section 5.1(b)(ii)(C) shall not apply to an Event of Default by the NiSource Member.

(c)If the Non-Contributing Member is an Investor Member and it refuses or fails to make its full Pro Rata Request Amount pursuant to this Section 5.1 on or prior to the applicable Capital Request Funding Date and the Contributing Member has not fully funded the Unfunded Amount in accordance with Section 5.1(b), then on or after the thirtieth (30th) day following the date of the applicable Contribution Unfunded Amount Notice, the Board may authorize the Company to seek additional equity funds on commercially reasonable terms from a Third Party in an amount up to the difference between the total Additional Funding Requirement requested and the total funds received by the Company from the Non-Contributing Member and the Contributing Member (including any additional funds that the Contributing Member may have contributed pursuant to Section 5.1(b)), and to issue Membership Interests to Third Parties in connection therewith pursuant to this Section 5.1(c). The terms and rights of the Membership Interests issued pursuant to this Section 5.1 must be on terms no better than the Membership Interests that would have been issued to the applicable Member had they been a Contributing Member. If the Board determines to seek additional equity funds from and issue Membership Interests to a Third Party pursuant to this Section 5.1(c), then the Company must

consummate such issuance within 180 days following the Capital Request Funding Date. If such issuance is not consummated within such 180-day period, then the Company’s right to so issue Membership Interests to a Third Party in connection with the applicable Additional Funding Requirement shall be lapsed, and the Company shall not thereafter issue any Membership Interests to a Third Party in connection with such Additional Funding Requirement; provided, that, if a definitive agreement providing for such issuance is executed prior to the expiration of such 180-day period but the issuance has not been consummated at the expiration of such period solely as a result of a failure to receive the requisite authorization, approval or consent of any Governmental Body in respect of such issuance, then such period shall be extended solely to the extent necessary to permit the receipt of all such authorizations, approvals or consents which are in process but have not been received from the relevant Governmental Body as of such original expiration date and the consummation of the issuance provided for in such definitive agreement; provided, further, that the Company shall have used its reasonable best efforts in seeking such authorizations, approvals and consents. Upon the completion of such issuance of Membership Interests pursuant to this Section 5.1(c), the Company shall give written notice to the Members of such issuance, which notice shall specify (i) the total number of new Membership Interests issued, (ii) the price per Membership Interest at which the Company issued the Membership Interests, and (iii) any other material terms of the issuance. Upon the issuance of new Membership Interests pursuant to this Section 5.1(c), the Contributing Member’s and Non-Contributing Member’s respective Percentage Interests will be adjusted accordingly. In no event shall any such issuance be subject to Section 7.1 or 8.1.

(d)If a Member does not make a Mandatory Capital Contribution or indicates in its Response to Capital Call that it shall make its Pro Rata Request Amount but then does not fund such amounts, such Member shall be a Defaulting Member, provided, that at any time the Defaulting Member is an Investor Member, then both Investor Members shall be deemed Defaulting Members until such Investor Member ceases to be a Defaulting Member according to the terms of this Agreement.

(e)In the event that there is an Investor Call Trigger, the NiSource Member (or its Affiliate) may (but is not required to), at its option at any time, acquire all (but not less than all) of the Membership Interests held by the Investor Members (the “Call Right”) by giving written notice (the “Call Notice”) to the BIP Investor Member of its election to exercise the Call Right; provided, that, other than with respect to clause (ii) or (iii) of the definition of Investor Call Trigger, the applicable Investor Member shall have sixty (60) days following the Call Notice to cure the event giving rise to the Call Notice, if capable of being so cured (the “Cure Period”). The purchase price payable by the NiSource Member in connection with the exercise of the Call Right shall be equal to the product of (i) with respect to an Investor Call Trigger pursuant to clause (i) of the definition thereof, 90% of the Fair Market Value of the Company, (ii) with respect to an Investor Call Trigger pursuant to clause (ii) of the definition thereof, 100% of the Fair Market Value of the Company and (iii) with respect to an Investor Call Trigger pursuant to clause (iii) of the definition thereof, the greater of 100% of the Fair Market Value of the Company or such amount which would satisfy the Spin Return Threshold (in each case, measured as of the date of the delivery of the Call Notice to the BIP Investor Member), multiplied (ii) by a fraction, (A) the numerator of which is the number of Membership Interests that the Investor Members own in the aggregate at such time and (B) the denominator of which is the total number of Membership Interests then outstanding (the amount equal to such product, the “Call Exercise Price”). If the Call Right is exercised by the NiSource Member, each of the Parties shall take all actions as may be reasonably necessary to consummate the transactions contemplated by this Section 5.1(e) as promptly as practicable, but in any event not later than thirty (30) days after the end of the Cure Period, or so long as necessary to obtain all required authorizations, approvals, or consents (such period, the “Call Consummation Period”), including entering into agreements and delivering certificates and instruments and consents as may be deemed necessary; provided, that, with respect to an Investor Call Trigger pursuant to clause (iii) of the definition thereof, the closing of the Call Right shall occur concurrently with or immediately prior to the underlying spin-off, split-off or similar transaction giving rise to the Call Right. If either Investor Member fails to take all actions necessary to consummate the Transfer of the Membership Interests held by it in accordance with this Section 5.1(e) prior to the expiration of the Call Consummation Period, then the Investor Members jointly shall be deemed to be in material breach of this Agreement for purposes of Article IV and for all other purposes hereunder, shall be deemed a Defaulting Member, and shall be deemed to have granted (and hereby grants, contingent only on the occurrence of such failure) an irrevocable appointment of any Person nominated for the purpose by the NiSource Member to be the Investor Members’ agent and

attorney to execute all necessary documentation and instruments on its behalf to Transfer the Investor Member’s Membership Interests to the Company as the holder thereof, in each case consistent with the provisions of this Section 5.1(e). At the consummation of any purchase and sale pursuant to this Section 5.1(e), the Investor Members shall sell to the NiSource Member all of the Membership Interests owned by the Investor Members in exchange for the Call Exercise Price. Contemporaneously with its receipt from the NiSource Member of the Call Exercise Price, the Investor Members shall Transfer to the NiSource Member all of the Membership Interests owned by the Investor Members, free and clear of all Liens. The Members and the Company acknowledge and agree that they shall cooperate reasonably to obtain any necessary authorization, approval or consent of any Governmental Body to consummate the transactions contemplated by this Section 5.1(e). For the avoidance of doubt, in the event the Call Right is exercised, the BIP Investor Member may request the Fair Market Value be determined in accordance with Section 13.15, regardless of the Investor Members’ aggregate Percentage Interest at such time.

(f)The BIP Investor Member has delivered to the Company on the Investment Closing Date the Equity Commitment Letter. In the event that either Investor Member fails to make any Mandatory Capital Contribution from the Investment Closing Date to and including the third (3rd) anniversary of the Investment Closing Date, and so long as the Maximum Investor Commitment has not been fully paid, the Company shall be entitled to enforce the Equity Commitment Letter for any portion of the Investor Members’ aggregate Pro Rata Request Amount, in addition to the other remedies provided herein (with the Directors appointed by the BIP Investor Member abstaining from determining any such enforcement).

(g)Notwithstanding anything contained herein to the contrary, to the extent the Company has not distributed one hundred percent (100%) of the Purchase Price (as defined in the PSA) to the NiSource Member prior to the Effective Date (any such shortfall, the “NiSource Shortfall Amount”), the NiSource Member shall have no obligation with respect to any Additional Funding Requirement pursuant to Section 5.1(a) unless or until the cumulative amount of any Additional Funding Requirement otherwise imposed upon the NiSource Member exceeds the NiSource Shortfall Amount, if any. For the avoidance of doubt, the NiSource Shortfall Amount, if any, shall in no way affect the Members’ Percentage Interests herein, and the NiSource Shortfall Amount, if any, shall not be Available Cash subject to distribution to the Members pursuant to Section 5.2.

Section 1.2Distributions Generally.

(a)Except as otherwise provided herein and subject to Section 5.2(b), Section 5.2(c), and the Act, no later than seventy-five (75) days after the end of each fiscal quarter, the Company shall make distributions in cash of all its Available Cash in respect of such fiscal quarter. The Company may make such other more frequent distributions (including interim distributions) at such times and in such amounts as the Board may determine.

(b)Except as otherwise provided herein, all distributions shall be paid to the Members only in cash and in the same proportion as their respective Percentage Interest; provided, that, in the case of distributions to be paid in respect of any period during which the Percentage Interest of the Members changed, such distributions shall be prorated to reflect the Percentage Interest of the Members on each day of such measurement period, and the Company and the Members shall take such action as necessary to effectuate such proration.

(c)With respect to each taxable year, at such times necessary to allow the Members to timely satisfy all of their U.S. federal, state and local and non-U.S. tax liabilities, prior to any distributions pursuant to Section 5.2(a) and subject to Available Cash and any restrictions contained in any loan agreement or other contract to which the Company is a party or by which it is bound, the Company shall make cash distributions (“Tax Distributions”) to each Member equal to such Member’s quarterly Assumed Tax Liability determined based on the Board’s good faith estimate of the projected Profits for such taxable year; provided, however, that to the extent a Member would otherwise be entitled to receive less than its Percentage Interest of the aggregate Tax Distributions to be paid pursuant to this Section 5.2(c) on any given date, then the Tax Distributions to such Member shall be increased, as necessary, to ensure that all such Tax Distributions made pursuant to this Section 5.2(c) are made pro rata in accordance with the Members’ respective Percentage Interests. The Company and the Board shall not have any liability to any Member for penalties arising from non-payment or incorrect estimates of such

Member’s estimated tax payments. Any distributions made pursuant to this Section 5.2(c) shall be treated for purposes of this Agreement as having been distributed pursuant to Section 5.2(a) and shall reduce, dollar-for-dollar, the amount otherwise distributable to such Member pursuant to Section 5.2(a). To the extent the Company does not have sufficient funds and thereby is unable to pay to the Members the full amount of any Tax Distribution otherwise payable pursuant to this Section 5.2(c), the Company shall pay the amount of such shortfall to the Members (pro rata, in accordance with the amount of any such shortfall then owning to such Members) as promptly thereafter as such funds become available. If with respect to any taxable year, the aggregate amount of distributions made to a Member under this Section 5.2(c) is in excess of the amount that would result from the application of this Section 5.2(c) to the entire taxable year, then the amount of such excess shall be treated as an advance against, and shall reduce the amount of, any future distributions made with respect to such Member pursuant to this Section 5.2(c), but shall not reduce Tax Distributions made to a Member to provide such Member with its pro rata Percentage Interest of Tax Distributions.

(d)Notwithstanding the terms of this Section 5.2 and any other provision of this Agreement, (i) the Company shall not make any distribution to any Member on account of its Membership Interests to the extent such distribution would violate the Act, other applicable Law or an Order, and (ii) a Member may direct the payment of part or all of any distribution to another Person by providing written notice of such direction to the Company.

Section 1.3Distributions upon the Occurrence of an Event of Dissolution. Upon the occurrence of an Event of Dissolution, the Board will proceed, subject to the provisions herein, to wind up the affairs of the Company, liquidate and distribute the remaining assets of the Company (provided, however, that all distributions shall be paid to the Members only in cash and in accordance with the following order of priority: (i) first, to the NiSource Member to the extent the NiSource Shortfall Amount, if any, exceeds the cumulative amount of any Additional Funding Requirement otherwise imposed upon the NiSource Member pursuant to Section 5.1(a), and (ii) second, to the Members in accordance with their Percentage Interests) and apply the proceeds of such liquidation in the order of priority in accordance with Section 18-804 of the Act or as may otherwise be agreed to by the Members; provided, however, that notwithstanding anything contained herein to the contrary, the NiSource Notes shall be paid first. If the assets of the Company remaining after the payment or discharge of all debts and liabilities of the Company are insufficient to return capital contributions of each Member, such Member shall have no recourse against the Company or any other Member.

Section 1.4Capital Accounts.

(a)A separate Capital Account for each Member shall be established on the books and records of the Company in compliance with Section 704(b) of the Code and the Treasury Regulations. The initial Capital Accounts of each Member are set forth on Schedule 1. This Section 5.4(a) and the other provisions of this Agreement relating to the maintenance of Capital Accounts are intended to comply with Treasury Regulation Sections 1.704-1(b) and 1.704-2, and shall be interpreted and applied in a manner consistent with such Treasury Regulation, as determined by the Board in its reasonable discretion.

(b)No Member shall be required to pay to any other Member or the Company any deficit or negative balance which may exist from time to time in such Member’s Capital Account (including upon and after dissolution of the Company).

Section 1.5Withdrawal of Capital; Interest. Except as expressly provided in this Agreement, (a) no Member may withdraw capital or receive any distributions from the Company and (b) no interest shall be paid by the Company on any capital contribution or distribution.

Section 1.6Allocation of Profits and Losses.

(a)Subject to Section 5.6(b), and after the application of the allocation rules in Section 5.7, Profits and Losses and, if the Board in its discretion determines it to be necessary, individual items thereof, for an Allocation Year (or other relevant period) shall be allocated among the Members for such Allocation Year (or other relevant period) in a manner determined by the Board so as to produce, as

nearly as possible, the sum of (a) the Capital Account balance for each Member at the end of such Allocation Year (or other relevant period) and (b) such Member’s share of Company Minimum Gain and Member Nonrecourse Debt Minimum Gain, if any, equal to the hypothetical cash that would be distributed to such Member if (x) the Company were dissolved, its affairs wound up and its assets sold for an amount of hypothetical cash equal to the sum of the Gross Asset Values of the assets at the end of such Allocation Year (or other relevant period), (y) the Company paid all of its liabilities in accordance with their terms up to the amount of the hypothetical cash (limited with respect to each Nonrecourse Liability to the Gross Asset Value of the asset securing such liability), and (z) the remaining hypothetical cash from the deemed sale were immediately distributed to the Members in accordance with Section 5.3.

(b)Notwithstanding the foregoing provisions of Section 5.6(a), the Losses (or items of expense or deduction or loss) allocated pursuant to Section 5.6(a) shall not exceed the maximum amount that can be so allocated without causing any Member to have an Adjusted Capital Account Deficit at the end of any Allocation Year (or other relevant period). In the event some, but not all, of the Members would have an Adjusted Capital Account Deficit as a consequence of an allocation of Losses pursuant to Section 5.6(a), the limitation set forth in this Section 5.6(b) shall be applied on a Member-by-Member basis so as to allocate the maximum permissible Losses to each Member under Treasury Regulations Section 1.704-1(b)(2)(ii)(d). All Losses (or items of expense or deduction or loss) in excess of the limitation set forth in this Section 5.6(b) shall be allocated to other Members in accordance with the positive balances in such Members’ Adjusted Capital Accounts so as to allocate the maximum permissible Losses to each Member under Treasury Regulations Section 1.704-1(b)(2)(ii)(d).

Section 1.7Special Allocations. Any allocation of Profits and Losses (or items thereof) for purposes of maintaining Capital Accounts will, however, be subject to any adjustment required to comply with Treasury Regulations Sections 1.704-1 and 1.704-2, including the following adjustments and special allocations which shall be made in the following order of priority and prior to any allocation under Section 5.6(a):

(a)Except as otherwise provided in Treasury Regulations Section 1.704-2(f), notwithstanding any other provision of this Article V, if there is a net decrease in Company Minimum Gain during an Allocation Year (or other relevant period), then each Member shall be specially allocated items of Company income and gain for such Allocation Year (or other relevant period) (and, if necessary, for subsequent Allocation Years (or other relevant periods)) in an amount equal to such Member’s share of the net decrease in Company Minimum Gain, determined in accordance with Treasury Regulations Section 1.704-2(g)(2). Allocations pursuant to the previous sentence shall be made in proportion to the respective amounts required to be allocated to each Member in accordance with Treasury Regulations Sections 1.704-2(f)(6) and 1.704-2(j)(2). This Section 5.7(a) is intended to comply with the minimum gain chargeback requirement of Treasury Regulations Section 1.704-2(f) and shall be interpreted consistently therewith.

(b)Except as otherwise provided in Treasury Regulations Section 1.704-2(i)(4), notwithstanding any other provision of this Article V, if there is a net decrease in Member Nonrecourse Debt Minimum Gain attributable to a Member Nonrecourse Debt during any Allocation Year (or other relevant period), then each Member who has a share of the Member Nonrecourse Debt Minimum Gain attributable to such Member Nonrecourse Debt, determined in accordance with Treasury Regulations Section 1.704-2(i)(5), shall be specially allocated items of Company income and gain for such Allocation Year (or other relevant period) (and, if necessary, for subsequent Allocation Years (or other relevant periods)) in an amount equal to such Member’s share of the net decrease in Member Nonrecourse Debt Minimum Gain attributable to such Member Nonrecourse Debt, determined in a manner consistent with the provisions of Treasury Regulations Section 1.704-2(i)(4). The items to be allocated shall be determined in accordance with Treasury Regulations Sections 1.704-2(i)(4) and 1.704-2(j)(2). This Section 5.7(b) is intended to comply with the Member nonrecourse debt minimum gain chargeback requirement of Regulations Section 1.704-2(i)(4) and shall be interpreted consistently therewith.

(c)If any Member unexpectedly receives an adjustment, allocation, or distribution of the type contemplated by Treasury Regulations Sections 1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5) or 1.704-1(b)(2)(ii)(d)(6) resulting in, or increasing, an Adjusted Capital Account Deficit for such Member, then items of Company income and gain shall be specially allocated to all such Members in an amount

and manner sufficient to eliminate, to the extent required by the Treasury Regulations, the Adjusted Capital Account Deficit of such Member as quickly as possible, provided that an allocation pursuant to this Section 5.7(c) shall be made only if and to the extent that such Member would have an Adjusted Capital Account Deficit after all other allocations provided for in this Article V have been tentatively made as if this Section 5.7(c) were not in this Agreement. It is intended that this Section 5.7(c) qualify and be construed as a “qualified income offset” within the meaning of Treasury Regulations Section 1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith.

(d)If any Member has an Adjusted Capital Account Deficit at the end of any Allocation Year (or other relevant period) in excess of the sum of (A) the amount such Member is required to restore pursuant to the provisions of this Agreement and (B) the amount such Member is deemed obligated to restore pursuant to Treasury Regulations Sections 1.704-2(g) and 1.704-2(i)(5), such Member shall be specially allocated items of Company income and gain in the amount of such deficit as quickly as possible; provided, however, that an allocation pursuant to this Section 5.7(d) shall be made only if and to the extent that such Member would have an Adjusted Capital Account Deficit after all other allocations provided for in this Section 5.7 have been tentatively made as if Section 5.7(c) and this Section 5.7(d) were not in this Agreement.

(e)To the extent that an adjustment to the adjusted tax basis of any Company asset pursuant to Code Section 734(b) is required, pursuant to Treasury Regulations Section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts as the result of a distribution to a Member in complete liquidation of its Membership Interest, the amount of such adjustment to the Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis), and such gain or loss shall be specially allocated to the Members in a manner consistent with the manner in which their Capital Accounts are required to be adjusted pursuant to Treasury Regulations Section 1.704-1(b)(2)(iv)(m).

(f)The Nonrecourse Deductions for each Allocation Year (or other relevant period) shall be allocated to the Members in proportion to their relative Percentage Interests.

(g)The Member Nonrecourse Deductions shall be allocated each Allocation Year (or other relevant period) to the Member that bears the economic risk of loss (within the meaning of Treasury Regulations Section 1.752-2) for the Member Nonrecourse Debt to which such Member Nonrecourse Deductions are attributable.

(h)The allocations set forth in Section 5.7(a) through Section 5.7(g) (collectively, the “Regulatory Allocations”) are intended to comply with certain requirements of the Treasury Regulations. It is the intent of the parties to this Agreement that, to the extent possible, all Regulatory Allocations will be offset in the current Allocation Year or future Allocation Years either with other Regulatory Allocations or with special allocations of other items of Company income, gain, loss or deduction pursuant to this Article V. Therefore, notwithstanding any other provision of this Section 5.7(h) (other than the Regulatory Allocations), the Board shall make such offsetting special allocations of Company income, gain, loss, or deduction (to the extent permissible) among the Members so that, after such offsetting allocations are made, each Member’s Capital Account balance is, to the extent possible, equal to the Capital Account balance such Member would have had if the Regulatory Allocations were not part of the Agreement and all Company items were allocated pursuant to Section 5.6(a).

Section 1.8Other Allocation Rules for Profits and Losses for Capital Accounts.

(a)In the event Members are admitted to the Company pursuant to this Agreement on different dates, the Company items of income, gain, loss, deduction, and credit allocated to the Members for each Allocation Year during which Members are so admitted shall be allocated among the Members in proportion to their respective interests during such Allocation Year using any reasonable convention permitted by Section 706 of the Code and selected by the Board (or its designee).

(b)In the event a Member transfers its Membership Interests during an Allocation Year, the allocation of Company items of income, gain, loss, deduction, and credit allocated to such Member and its transferee for such Allocation Year shall be made between such Member and its transferee in accordance

with Section 706 of the Code using any reasonable convention permitted by Section 706 of the Code and selected by the Board (or its designee).

Section 1.9Tax Allocations; Code Section 704(c) Allocations.

(a)Except as provided in this Section 5.9, for income tax purposes under the Code and the Treasury Regulations each Company item of income, gain, loss, deduction and credit shall be allocated among the Members in the same manner as its correlative item of Profit and Loss for the Allocation Year (or other relevant period).

(b)In accordance with Code Section 704(c) and the Treasury Regulations, items of income, gain, loss, and deduction with respect to any property of the Company shall, solely for income tax purposes, be allocated among the Members so as to take account of any variation between the adjusted tax basis of such property and its initial Gross Asset Value pursuant to any permissible method under the Treasury Regulations as may be determined by the Partnership Representative in its discretion; provided, however, with respect to any Company asset that is contributed to the Company with a Gross Asset Value that varies from its basis in the hands of the contributing Member immediately preceding the date of contribution shall be allocated among the Members for income tax purposes using the “traditional method,” with no “curative allocation” of income or gain to offset any “shortfall” in depreciation that results by reason of the use of the “traditional method,” as defined in Treasury Regulations Section 1.704-3(b), including upon sale of any property or upon the a subsequent issuance of additional membership interests, an in-kind contribution of property to the Company in exchange for membership interest, or a redemption of membership interests.

(c)If any portion of gain recognized from the disposition of assets by the Company represents the “recapture” of previously allocated deductions by virtue of the application of Code Section 1245 or 1250 (the “Recapture Gain”), such Recapture Gain shall be allocated, solely for income tax purposes, in accordance with Treasury Regulations Sections 1.1245-1(e)(2) and (3) and 1.1250-1(f).

(d)Tax credits and tax credit recapture shall be allocated among the Members in accordance with any reasonable method selected by the Board (or its designee) that is permitted by applicable tax laws.

(e)Unless otherwise provided in this Section 5.9, any material elections or other decisions relating to allocations for income tax purposes, including selecting any allocation method under Treasury Regulation Section 1.704-3, shall be made by the Board and shall reflect the economic intent of parties.

(f)Allocations pursuant to this Section 5.9 are solely for income tax purposes and shall not affect, or in any way be taken into account in computing, any Member’s Capital Account.

Section 1.10Allocation of Liabilities. The liabilities of the Company shall be allocated to the Members in any manner permitted under Code Section 752 and Treasury Regulations promulgated thereunder and as selected by the Board (or its designee); provided, however, for the avoidance of doubt, NIPSCO’s intercompany debt payable to Parent as of Closing is recourse debt and shall be allocated one hundred percent (100%) to NIPSCO Holdings I under Treasury Regulations Section 1.752-2(c) for disguised sale and basis purposes.

Section 1.11Compliance with Tax Laws. The allocation rules set forth in Section 5.6 through Section 5.10 are intended to comply with the Code and Treasury Regulations and to ensure that all allocations under this Article V are respected for United States federal income tax purposes and shall be interpreted consistently with such intent. If, for any reason, the Board determines that any provision of Section 5.6 through Section 5.10 does not comply with the Code or Treasury Regulations or that the allocations under this Article V may not be respected for United States federal income tax purposes, the Board may, subject to the next sentence, take all reasonable actions, including amending this Article V or adjusting a Member’s Capital Account or how Capital Accounts are maintained, to ensure compliance with the Code and Treasury Regulations and that the allocations provided for in this Article V shall be respected for United States federal income tax purposes. Nothing in this Section 5.11 shall permit any changes to the provisions of Section 5.2 or Section 5.3.

Section 1.1General Restriction.

(a)No Member shall Transfer any of its Membership Interests except pursuant to and in accordance with this Article VI. Any purported Transfer by any Member of its Membership Interests in violation of this Section 6.1(a), or without compliance in all respects with the provisions of this Article VI pertaining to such purported Transfer, shall be invalid and void ab initio, and such purported Transfer by such Member shall constitute a material breach of this Agreement for purposes of Article VI.

(b)Subject to Section 6.2, neither the Investor Members nor the NiSource Member may Transfer any of its or their Membership Interests to any Person prior to the date that is the third (3rd) anniversary of the Investment Closing Date (the “Lock-Up Period”), other than (i) in connection with any spin off, split off or similar transaction of the Company, the NiSource Member or NIPSCO, or any of their Affiliates, in each case, subject to the NiSource Member’s compliance with Section 5.1(e) or Section 6.5 and the satisfaction of the Spin Return Threshold, or (ii) with the prior written consent of the NiSource Member, on the one hand, or the BIP Investor Member, on the other hand, as applicable. After the expiration of the Lock-Up Period, each of the Investor Members and the NiSource Member, as applicable, may Transfer its Membership Interests in accordance with this Article VI. Notwithstanding the forgoing, each of the Members may at any time Transfer Membership Interests in compliance with Section 6.2.

(c)Transfers by Members in accordance with and pursuant to this Article VI shall entitle each applicable transferee to the rights and obligations of the transferor under this Agreement.

(d)The Investor Members and the NiSource Member acknowledge any indirect Transfers of any Member’s Membership Interest shall be deemed a Transfer by such Member hereunder. The Parent has joined this Agreement solely for the purpose of acknowledging the obligations of the NiSource Member under this Article VI.

Section 1.2Transfers to Permitted Transferees; Liens by Members.

(a)Notwithstanding Section 6.1, each of the Members may Transfer at any time all or any portion of the Membership Interests held by it to any one of its Permitted Transferees; provided, that, in connection with any such Transfer, (a) such Permitted Transferee shall, in writing, assume all of the rights and obligations of the transferring Member as a Member under this Agreement and as a Party hereto with respect to the Transferred Membership Interests, (b) such Permitted Transferee is as creditworthy as the transferring Member and provides evidence thereof to the non-transferring Members, (c) the transferring Member remains liable for all liabilities and obligations of the Permitted Transferee, and (d) effective provision shall be made whereby such Permitted Transferee shall be required, prior to the time when it shall cease to be a Permitted Transferee of the transferring Member, to Transfer such Membership Interests to the transferring Member or to another Person that would be a Permitted Transferee of the transferring Member as of such applicable time. In the event that a Member (including, as the case may be, a Permitted Transferee) intends to Transfer its Membership Interests to a Permitted Transferee, such transferring Member or the Permitted Transferee, as applicable, shall notify the other Members and the Company of the intended Transfer at least twenty (20) Business Days prior to the intended Transfer.

(b)Each Member shall be permitted to directly or indirectly Encumber its Membership Interests or any equity interests in such Member in connection with any debt financing, the proceeds of which have been or will be used by such Member to finance its purchase of such Membership Interests (whether in respect of an issuance of new Membership Interests by the Company or the purchase of existing Membership Interests from a Member or the refinancing of any such debt financing in the future), to fund the capital expenditure needs of the Company and its Subsidiaries or to fund its capital needs for any Mandatory Capital Contribution and neither such Lien nor any commencement or consummation of foreclosure proceedings or exercise of foreclosure remedies by a secured party on a Member’s Membership Interests Encumbered in connection with any such debt financing shall, in either case, be considered a “Transfer” for any purpose under this Agreement; provided, that (i) such Member

shall be obligated to promptly notify the other Members and the Company in writing following the commencement of any such foreclosure remedies or proceedings, (ii) in the event of the consummation of such a foreclosure, such Member will automatically cease to be deemed the owner of the Membership Interests so foreclosed and will cease to have any rights in respect thereof (with the financing source foreclosing on such Membership Interests succeeding to the rights and responsibilities of the Member hereunder), and (iii) the consummation of any such foreclosure will be subject to the receipt of any required authorization, approval or consent of all applicable Governmental Bodies; provided, further, following exercise of any foreclosure or similar rights, such lender or similar Person may not further Transfer such Membership Interests without complying with this Article VI, including, Section 6.3.

Section 1.3Right of First Offer.

(a)Prior to any Transfer by a Member (each, a “Transferring Member”) of all or any portion of its Membership Interests other than to a Permitted Transferee of such Transferring Member, the Transferring Member must first offer to sell to the other Members (the “Non-Transferring Member”; provided, that (x) if the Transferring Member is an Investor Member, the other Investor Member shall not be deemed a Non-Transferring Member for any purpose under this Section 6.3 and (y) if the Transferring Member is the NiSource Member, the Investor Members jointly shall be deemed the Non-Transferring Member for all purposes under this Section 6.3) all of its Membership Interests that it desires to sell (such Membership Interests to be offered for sale to the Non-Transferring Member pursuant to this Section 6.3, the “Subject Membership Interests”), in each case, in accordance with the procedures set forth in the provisions of this Section 6.3.

(i)The Transferring Member shall first deliver to the Non-Transferring Member a written notice which shall be a binding offer (a “Sale Notice”) setting forth the cash price and all of the other material terms and conditions at which the Transferring Member is willing to sell the Subject Membership Interests to the Non-Transferring Member, which notice shall constitute an offer to the Non-Transferring Member to effect such purchase and sale on the terms set forth therein. Any such Sale Notice shall be firm, not subject to withdrawal and prepared and delivered in good faith. Within ninety (90) days following its receipt of a Sale Notice, the Non-Transferring Member may accept the Transferring Member’s offer and purchase the Subject Membership Interests at the cash price and upon the other material terms and conditions set forth in the Sale Notice, in which event the closing of the purchase and sale of the Subject Membership Interests will take place as promptly as practicable, subject to customary closing conditions, including the receipt of required regulatory approvals. The Sale Notice shall contain representations and warranties by the Transferring Member to the Non-Transferring Member that (A) the Transferring Member has full right, title and interest in and to the Subject Membership Interests, (B) the Transferring Member has all the necessary power and authority and has taken all necessary action to Transfer the Subject Membership Interests to the Non-Transferring Member as contemplated by this Section 6.3, and (C) the Subject Membership Interests are free and clear of any and all Liens other than those arising as a result of or under the terms of this Agreement and those arising under securities Laws of general applicability pertaining to limitations on the transfer of unregistered securities or (D) such other customary representations and warranties.

(ii)If the Non-Transferring Member does not accept the Transferring Member’s offer within such ninety (90)-day period, then the Transferring Member will, for a period of 180 days commencing on the earlier of (A) the expiration of such ninety (90)-day period and (B) the delivery of a written notice by the Non-Transferring Member to the Transferring Member rejecting the offer set forth in the Sale Notice (if any) (such 180-day period, the “Sale Period”), be entitled to sell the Subject Membership Interests to any one Third Party at the same or higher price and upon other terms and conditions (excluding price) that are not more favorable to the acquiror than those specified in the Sale Notice, subject to the other terms of this Section 6.3. If such sale to any Third Party is not completed prior to the expiration of the Sale Period, then the process initiated by the delivery of the Sale Notice shall be lapsed, and the Transferring Member will be required to repeat the process set forth in this Section 6.3 before entering into any agreement with respect to, or consummating, any sale of Membership Interests to any Third Party; provided, that if a definitive agreement providing for the consummation of such sale is executed within the Sale Period but such sale has not been consummated at the expiration of the Sale Period solely as a result of a failure to receive the requisite authorization, approval or consent of any Governmental Body in respect of such sale, then the Sale Period shall be extended solely to the extent

necessary to permit the receipt of all such authorizations, approvals or consents which are in process but have not been received from the relevant Governmental Body as of the original expiration date of the Sale Period and the consummation of the sale provided for in such definitive agreement; provided, that the Transferring Member shall have used efforts in seeking such authorizations, approvals and consents, consistent with its obligations under such definitive agreements in respect thereof.

(b)The Investor Members and their respective Permitted Transferees (if any) shall not be permitted to Transfer any of their Membership Interests to a Prohibited Competitor without the prior written consent of the NiSource Member. Within ten (10) Business Days after January 1, 2024 (and each year thereafter during the ten (10) Business Day period beginning on January 1 of the applicable year), the NiSource Member shall have the right (i) to update the list of Prohibited Competitors set forth on Appendix (A) to replace no more than three (3) of the Prohibited Competitors with other Competitors designated by the NiSource Member, and (ii) in addition to any replacements pursuant to clause (i), to add up to two (2) additional Competitors designated by the NiSource Member to such list.

(c)No Transfer of Membership Interests by an Investor Member to any Third Party pursuant to Section 6.3(a)(ii) may be effected if it would, or would reasonably be expected to in the reasonable and good faith determination of the NiSource Member in consultation with the Board, (i) have a material and adverse effect on the Company Group or (ii) create a material risk of a material adverse regulatory consequence on any member of the Company Group or the Outside Group as a result of the identity of the Third Party transferee, any action taken or reasonably expected to be taken by any Governmental Body with respect to such Transfer or change in Tax status of any Person caused or reasonably expected to be caused by such Transfer, any terms or conditions of such Transfer, any requirement that the Membership Interests be registered under any applicable securities Laws in connection with or as a result of such Transfer, or any other similar matter. For purposes of this Section 6.3 and Section 6.4, “control” means (x) the ownership of at least a majority of the issued and outstanding Membership Interests of the Company, or (y) the ability to elect, directly or indirectly, a majority of the Directors of the Company in accordance with this Agreement.

(d)Prior to the consummation of any Transfer pursuant to Section 6.3(a)(ii), the Transferring Member shall have delivered to the Board and the Non-Transferring Member evidence reasonably satisfactory to the Board (with the Directors appointed by the Transferring Member abstaining from any such determination) and to the Non-Transferring Member that (i) the transferee is a Qualified Transferee and (ii) the Transfer complies with the provisions of Section 6.3(b) (if applicable) and Section 6.3(c).

Section 1.4Tag-Along Rights.

(a)Other than with respect to a Transfer proposed and made in accordance with Section 6.5, in the event that the NiSource Member proposes to effect a Transfer to a Third Party transferee (the “Tag-Along Buyer”) of a number of its Membership Interests constituting more than 25% of the total Membership Interests then outstanding (a “Tag-Along Sale”), then the NiSource Member shall give the Investor Members written notice (a “Tag-Along Notice”) of such proposed Transfer at least thirty (30) days prior to the consummation of such Tag-Along Sale, setting forth (w) the number of Membership Interests (“Tag-Along Offered Membership Interests”) proposed to be Transferred to the Tag-Along Buyer and the purchase price, (x) the identity of the Tag-Along Buyer, (y) any other material terms and conditions of the proposed Transfer and (z) the intended dates on which the NiSource Member will enter into a definitive agreement in respect of such proposed Transfer and consummate such proposed Transfer.

(b)Upon delivery of a Tag-Along Notice, the Investor Members shall have the right to sell up to their respective Tag Portions, at the same price per Membership Interest, for the same form of consideration and pursuant to the same terms and conditions (including time of payment) as set forth in the Tag-Along Notice (or, if different, as such are applicable at the time of the entry into a definitive agreement in respect of, or at the time of the consummation of, the Tag-Along Sale). If an Investor Member wishes to participate in the Tag-Along Sale, then such Investor Member shall provide written notice to the NiSource Member no less than forty-five (45) days after the date of the Tag-Along Notice, indicating such election, provided however if the BIP Investor Member elects to sell its respective Tag Portion the VCOC Investor Member shall be required to sell its respective Tag Portion on the same terms set forth in the election notice by the BIP Investor Member. Such notice shall set forth the number of its

Membership Interests that such Investor Member elects to include in the Tag-Along Sale (which number shall not exceed its Tag Portion), and such notice shall constitute such Investor Member’s binding agreement to sell such Membership Interests on the terms and subject to the conditions applicable to the Tag-Along Sale.

(c)Any Transfer of an Investor Member’s Membership Interests in a Tag-Along Sale shall be on the same terms and conditions as the Transfer of the NiSource Member’s Membership Interests in such Tag-Along Sale, except as otherwise provided in this Section 6.4(c). Any participating Investor Member shall be required to make customary representations and warranties in connection with the Transfer of its Membership Interests, including as to its ownership and authority to Transfer, free and clear of all Liens, such Membership Interests and shall indemnify and hold harmless, to the fullest extent permitted by applicable Law, the Tag-Along Buyer against all losses of whatever nature arising out of, in connection with or related to any breach of any representation or warranty made by, or agreements, understandings or covenants of such Investor Member, as the case may be, under the terms of the agreements relating to such Transfer of such Investor Member’s Membership Interests, in each case not to exceed the equivalent obligations to indemnify and hold harmless the Tag-Along Buyer provided by the NiSource Member; provided, that (i) liability for misrepresentation or indemnity shall (as between the NiSource Member and any such Investor Member) be expressly stated to be several but not joint and the NiSource Member and any such Investor Member shall not be liable for any breach of covenants or representations or warranties as to the Membership Interests of any other Member and shall not, in any event, be liable for more than its pro rata share (based on the proceeds to be received) of any liability for misrepresentation or indemnity, (ii) any participating Investor Member shall benefit from any releases of sellers or other provisions in the transaction documentation of general applicability to sellers to the same extent as the NiSource Member, (iii) any participating Investor Member shall not be obligated to agree to any non-customary administrative covenants (such as any non-compete covenants that would restrict its or its Affiliates’ business activities), and (iv) any participating Investor Member shall not be obligated to provide indemnification obligations that exceed its proceeds from the Tag-Along Sale.

(d)Notwithstanding the foregoing, and for the avoidance of doubt, no Investor Member shall be entitled to Transfer its Membership Interests pursuant to this Section 6.4 in the event that, notwithstanding delivery of a written notice of election to participate in such Tag-Along Sale pursuant to this Section 6.4, such Investor Member fails to consummate the Transfer of its Membership Interests (on the terms and conditions required by this Section 6.4) in the applicable Tag-Along Sale.

(e)For the avoidance of doubt, the rights conferred to each Investor Member under this Section 6.4 do not apply in the event of a Change in Control of the NiSource Member.

Section 1.5Drag-Along Rights.

(a)Following the end of the Lock-Up Period, except for the exclusions set forth in Section 6.1(b) thereto, in the event that the NiSource Member intends to effect a sale of all or any portion of the Membership Interests owned by the NiSource Member and such Membership Interests constitute at least a majority of the issued and outstanding Membership Interests of the Company (a “Drag-Along Sale”), then the NiSource Member shall have the option (but not the obligation) to require each Investor Member to Transfer all of its Membership Interests to the Third Party buyer (the “Drag-Along Buyer”) (or to such other Party as the Drag-Along Buyer directs) in accordance with the provisions of this Section 6.5 (such right of the NiSource Member, the “Drag-Along Right”).

(b)If the NiSource Member elects to exercise the Drag-Along Right pursuant to Section 6.5(a), then the NiSource Member shall send a written notice to each applicable Investor Member (a “Drag-Along Notice”) specifying (i) that such Investor Member is required to Transfer all of its Membership Interests pursuant to this Section 6.5, (ii) the amount and form of consideration payable for such Investor Member’s Membership Interests, (iii) the name of the Third Party to which such Investor Member’s Membership Interests are to be Transferred (or which is otherwise entitled to direct the disposition thereof at the consummation of the Drag-Along Sale), (iv) any other material terms and conditions of the proposed Transfer and (v) the intended dates on which the NiSource Member will enter into a definitive agreement in respect of such proposed Transfer and consummate such proposed Transfer.

(c)In the event that the NiSource Member elects to exercise the Drag-Along Right, then each Investor Member hereby agrees with respect to all Membership Interests it holds:

(i)in the event such transaction requires the approval of Members, to vote (in person, by proxy or by action by written consent, as applicable) all of its Membership Interests in favor of such Drag-Along Sale;

(ii)to execute and deliver all related documentation and take such other action reasonably necessary to enter into definitive agreements in respect of and to consummate the proposed Drag-Along Sale in accordance with, and subject to the terms of, this Section 6.5; and

(iii)not to deposit its Membership Interests in a voting trust or subject any Membership Interests to any arrangement or agreement with respect to the voting of such Membership Interests, unless specifically requested to do so by the Drag-Along Buyer in connection with a Drag-Along Sale.

(d)Subject to Section 6.5(e), any Transfer of an Investor Member’s Membership Interests in a Drag-Along Sale shall be on the same terms and conditions as the proposed Transfer of the NiSource Member’s Membership Interests in the Drag-Along Sale. Upon the request of the NiSource Member, each Investor Member shall be required to make customary representations and warranties in connection with the Transfer of such Investor Member’s Membership Interests, including as to its ownership and authority to Transfer, free and clear of all Liens, its Membership Interests, and shall indemnify and hold harmless, to the fullest extent permitted by applicable Law, the Drag-Along Buyer against all losses of whatever nature arising out of, in connection with or related to any breach of any representation or warranty made by, or agreements, understandings or covenants of such Investor Member as the case may be, under the terms of the agreements relating to such Transfer of such Investor Member’s Membership Interests, in each case not to exceed the equivalent obligations to indemnify and hold harmless the Drag-Along Buyer provided by the NiSource Member; provided, that (i) liability for misrepresentation or indemnity shall (as between the NiSource Member and such Investor Member) be expressly stated to be several but not joint and the NiSource Member and such Investor Member shall not be liable for any breach of covenants or representations or warranties as to the Membership Interests of any other Member and shall not, in any event, be liable for more than its pro rata share (based on the proceeds to be received) of any liability for misrepresentation or indemnity, (ii) such Investor Member shall benefit from any releases of sellers or other provisions in the transaction documentation of general applicability to sellers to the same extent as the NiSource Member and (iii) such Investor Member shall not be obligated to provide indemnification obligations that exceed its proceeds from the Drag-Along Sale.

(e)Any Transfer required to be made by an Investor Member pursuant to this Section 6.5 shall be for consideration consisting of cash or cash equivalents (or a combination thereof). Without the consent of the applicable Investor Member, an Investor Member shall not be required in connection with such Drag-Along Sale to agree to any material indemnification obligations, material, non-customary administrative covenants (including, but not limited to, restrictive covenants (such as non-solicit and non-compete covenants) that would restrict its or its Affiliates’ business activities).

(f)At the consummation of the Drag-Along Sale, each Investor Member shall Transfer all of its Membership Interests to the Drag-Along Buyer (or its designee), and the Drag-Along Buyer shall pay the consideration due for such Investor Member’s Membership Interest. If either Investor Member has failed, as of immediately prior to the time that the consummation of the Drag-Along Sale would otherwise have occurred, to have taken all actions necessary in accordance with this Agreement to consummate the Transfer of the Membership Interests held by it, then such Investor Member shall be deemed to be in material breach of this Agreement for purposes of Article IV and for all other purposes hereunder, shall be a Defaulting Member, and shall be deemed to have granted (and hereby grants, contingent only on the occurrence of such failure) an irrevocable appointment of any Person nominated for the purpose by the NiSource Member to be such Investor Member’s agent and attorney to execute all necessary documentation and instruments on its behalf to Transfer such Investor Member’s Membership Interest to the Drag-Along Buyer (or as it may direct) as the holder thereof, in each case consistent with the terms set forth in this Section 6.5.

(g)The NiSource Member shall have a period of 180 days commencing on the delivery of the Drag-Along Notice (such 180-day period, the “Drag Sale Period”) to consummate the Drag-Along Sale. If the Drag-Along Sale is not completed prior to the expiration of the Drag Sale Period, then the process initiated by the delivery of the Drag-Along Notice shall be lapsed, and the NiSource Member will be required to repeat the process set forth in this Section 6.5 to pursue any Drag-Along Sale; provided that if a definitive agreement providing for the consummation of such Drag-Along Sale is executed within the Drag Sale Period but such Drag-Along Sale has not been consummated at the expiration of the Drag Sale Period solely as a result of a failure to receive the requisite authorization, approval or consent of any Governmental Body in respect of such Drag-Along Sale, then the Drag Sale Period shall be extended solely to the extent necessary to permit the receipt of all such authorizations, approvals or consents which are in process but have not been received from the relevant Governmental Body as of the original expiration date of the Drag Sale Period and the consummation of the Drag-Along Sale provided for in such definitive agreement; provided, that the NiSource Member shall have used efforts in seeking such authorizations, approvals and consents consistent with its obligations under such definitive agreement(s) in respect thereof.

(h)Notwithstanding the foregoing, the NiSource Member may not exercise the Drag-Along Right or consummate any Drag-Along Sale, without the prior written consent of the BIP Investor Member unless the applicable Drag-Along Sale would result in the Investor Members receiving proceeds resulting in the Investor Members collectively achieving at least a IRR of 10% (the “Investor Return Threshold”) and a MOIC of 2.15x (the “MOIC Return Threshold”); provided, that any shortfall in the Investor Members collectively achieving the Investor Return Threshold or the MOIC Return Threshold may be paid by the NiSource Member to the Investor Members in immediately available funds at the closing of the Drag-Along Sale, in which case the prior written consent of the BIP Investor Member shall not be required to exercise the Drag-Along Right or consummate such Drag- Along Sale.

(i)For the avoidance of doubt, the rights conferred to the NiSource Member under this Section 6.5 do not apply in the event of a Change in Control of the NiSource Member.

Section 1.6Cooperation. The transferring Member acknowledges and agrees that it shall cooperate reasonably to obtain the requisite authorization, approval or consent of any Governmental Body necessary to consummate any Transfers contemplated or permitted by this Article VI. The Members shall have the right in connection with any Transfer of Membership Interests permitted by this Agreement (or in connection with the investigation or consideration of any such potential Transfer) to require the Company to reasonably cooperate with potential purchasers in such prospective Transfer (at the sole cost and expense of the applicable Member or such potential purchasers) by taking such actions reasonably requested by the applicable Member or such potential purchasers to cooperate in such Transfer, including (a) preparing or assisting in the preparation of due diligence materials and (b) providing such reasonable access to the Company’s and each of its Subsidiaries’ books, records, properties and other materials (subject, in each case, to the execution of customary confidentiality and non-disclosure agreements and subject to attorney-client privilege) to potential purchasers; provided that no such cooperation by the Company shall be required (i) until the relevant potential purchaser executes and delivers to the Company a customary confidentiality agreement, (ii) to the extent such cooperation would unreasonably interfere with the normal business operations of the Company or any of its Subsidiaries, and (iii) to the extent the provision of any information would (A) conflict with, or constitute a violation of, any applicable Law or Order or cause a loss of attorney-client privilege of the Company or any of its Subsidiaries, (B) in the NiSource Member’s reasonable determination, require the disclosure of any information that is proprietary, confidential or sensitive to the NiSource Member or to any member of the NiSource Outside Group, or (C) require the disclosure of any information relating to any joint, combined, consolidated or unitary Tax Return that includes the NiSource Member or any other member of the Outside Group or any supporting work papers or other documentation related thereto.

sale or transfer such that the Blocker Seller is able to sell, equity interests in such Investor Member (or, as applicable, the regarded owner of such Investor Member for U.S. federal income tax purposes), in lieu of selling the Membership Interests held (directly or indirectly) by such Investor Member in exchange for consideration equal to the value of the Membership Interests as determined in such sale pursuant to Section 6.3, Tag-Along Sale or Drag-Along Sale or other Transfer, held (directly or indirectly) by such Investor Member without discount (as appropriately adjusted for any partial sale).

Section 1.1Preemptive Rights

. The Company hereby grants to each Member the right to purchase such Member’s Preemptive Right Share of all (or any part) of any New Securities that the Company may from time to time issue after the Effective Date (the “Preemptive Right”); provided, however, that the Preemptive Right shall not apply with respect to New Securities issues or to be issued in any public offering or pursuant to failures to fund Additional Funding Requirements or as otherwise specifically provided herein. In the event the Company proposes to undertake an issuance of New Securities (in a single transaction or a series of related transactions), the Company shall give to each Member written notice of its intention to issue New Securities (the “Preemptive Right Participation Notice”), describing the amount and type of New Securities, the cash purchase price and the general terms upon which it proposes to issue such New Securities. Each Member shall have twenty (20) days from the date of receipt of any such Preemptive Right Participation Notice (the “Preemptive Right Notice Period”) to agree in writing to purchase for cash up to such Member’s Preemptive Right Share of such New Securities for the price and upon the terms and conditions specified in the Preemptive Right Participation Notice by giving written notice to the Company and stating therein the quantity of New Securities to be purchased (not to exceed such Members’ Preemptive Right Share) as well as the maximum amount of New Securities it would purchase. If any Member fails to so respond in writing within the Preemptive Right Notice Period, then such Member shall forfeit the right hereunder to purchase its Preemptive Right Share of such New Securities and the Company will allocate the rights to purchase such New Securities to any other Member that indicated it would purchase New Securities in excess of its Preemptive Right Share based on their relative Preemptive Right Shares. Subject to obtaining the requisite authorization, approval or consent of any Governmental Body, the closing of any purchase by any Member pursuant to this Section 7.1 shall be consummated concurrently with the consummation of the issuance or sale described in the Preemptive Right Participation Notice. The Company shall be free to complete the proposed issuance or sale of New Securities described in the Preemptive Right Participation Notice with respect to any New Securities not elected to be purchased pursuant to this Section 7.1 in accordance with the terms and conditions set forth in the Preemptive Right Participation Notice (except that the amount of New Securities to be issued or sold by the Company may be reduced). If a Member indicates in its response to a Preemptive Right Participation Notice that it shall purchase New Securities but then does not fund such amounts, such Member shall be a Defaulting Member.

All Members shall cooperate in good faith to amend this Section 10.2 or other provisions of this Agreement as necessary to reflect any statutory amendments or the promulgation of Treasury Regulations or other administrative authority promulgated under the Partnership Audit Rules so as to, to the extent possible, preserve the relative rights, duties, and obligations of the Members hereunder. The Company shall, to the fullest extent permitted by law, reimburse and indemnify the Partnership Representative for all third-party expenses (including legal and accounting fees), claims, liabilities, losses, and damages incurred as the Partnership Representative in connection with any examination, administrative, or judicial proceeding, or otherwise acting in its capacity as Partnership Representative.

(b)Notwithstanding anything to the contrary in this Agreement, each Member (including, for purposes of this Section 10.2, any Person who is or becomes a Member but who for any reason ceases to be a Member) (i) hereby covenants to treat each item of income, gain, loss, deduction, or credit attributable to the Company in a manner consistent with the treatment of such income, gain, loss deduction, or credit on the tax return of the Company or as determined in a notice of final partnership adjustment pursuant to Section 6226 of the Code, (ii) hereby agrees to indemnify and hold harmless the Company from such Member’s share of any tax and any penalties, interest, and additions to tax attributable to any adjustment to the income, gain, loss, deduction, or credit of the Company pursuant to Section 6226 of the Code, and (iii) hereby agrees to take all other actions as the Partnership Representative may reasonably direct with respect to the Member’s (or, in respect of the Member, the Company’s) tax liabilities, which shall not include filing an amended return for any “reviewed year” to account for all adjustments under Section 6225(a) of the Code properly allocable to the Member as provided in and otherwise contemplated by Section 6225(c) of the Code and any Treasury Regulations that may be promulgated thereunder. If the Company or any other entity in which the Company holds an interest is obligated to pay any amount to a governmental agency or body or to any other Person (or otherwise makes a payment) of any taxes arising under a federal, state, or local tax audit or other proceeding and the Partnership Representative determines that all or a portion of such payment is specifically attributable to a Member (or former Member), then such Member (or former Member) shall reimburse the Company in full for the entire amount paid (including any interest, penalties, and expenses associated with such payment). The obligations of a Member under this Section 10.2 shall survive such Member’s sale or other disposition of its interests in the Company and the termination, dissolution, liquidation, or winding up of the Company.

(c)The Partnership Representative (i) shall keep the Investor Members reasonably informed of any material tax audit, settlement or proceeding and (ii) shall not settle or otherwise compromise a material tax audit, settlement or proceeding that would have a material adverse impact on either Investor Member, without the BIP Investor Member’s prior written consent (such consent not to be unreasonably withheld, conditioned, or delayed).

Section 1.3Tax Elections. Except as otherwise provided by this Agreement, all material elections and decisions required or permitted to be made by the Company under any applicable tax law shall be determined by the NiSource Member; provided however, that any election with respect to taxes that is disproportionately materially adverse to either Investor Member shall require the BIP Investor

Member’s prior consent (such consent not to be unreasonably withheld, conditioned, or delayed). The elections shall include, but not be limited to, the following:

(a)Upon the written request of a Member, the Company may make the election under Section 754 of the Code in accordance with applicable regulations thereunder for the Company and each applicable Subsidiary;

(b)To the extent permitted under Section 706 of the Code, to elect the calendar year as the Company’s taxable year and, (i) for clarity, to the extent the Company is permitted to adopt the calendar year, no other year shall be adopted as the taxable year and (ii) to the extent any additional filings or elections are required, to make such required filings or elections;

(c)To elect the accrual method of accounting;

(d)To elect to amortize any organizational expenses of the Company ratably over a period of one hundred eighty (180) months as permitted by Section 709(b) of the Code, and to elect to deduct the start-up expenditures of the Company as permitted by Section 195(b) of the Code;

(e)If “bonus depreciation” is available with respect to qualified property, the NiSource Member shall make the election described in Section 168(k)(7) of the Code to opt out of “bonus depreciation” for the Taxable Year during which the placed in service date occurs.

(f)Based upon current knowledge of the facts pertaining to the transactions contemplated by the PSA as of the Investment Closing Date, the Company will not report the transactions contemplated by the PSA to the IRS as a “reportable transaction” pursuant to Section 6011 of the Code, the relevant Treasury Regulations and any other administrative practice or procedure;

(g)To the extent permitted by law, to elect to apply the de minimis safe harbor under Treasury Regulations Section 1.263(a)-1(f);

(h)To the extent permitted under Code Section 461(h)(3), to elect the adoption of the exception for certain recurring items;

(i)To the extent permitted under Code Section 461(c), to elect to ratably accrue real property taxes; and

(j)To elect under Code Section 163(j) to be treated as an excepted trade or business.

Section 1.4Cooperation. Each Investor Member shall, and shall cause its Affiliates to, provide to the NiSource Member and its Subsidiaries (including the Company and its Subsidiaries), and the NiSource Member and the Company shall, and shall cause their Affiliates to, provide to each Investor Member, in each case, such cooperation, documentation and information as any of them reasonably may request in connection with (a) filing any Tax Return, amended Tax Return or claim for refund, (b) determining a liability for Taxes or (c) preparing for or conducting any Tax audits, examinations or other proceedings by any taxing authority of any Governmental Body.

Section 1.5Withholding

. The Company may withhold and pay over to the United States Internal Revenue Service (or any other relevant Tax authority) such amounts as it is required to withhold or pay over, pursuant to the Code or any other applicable Tax Law, on account of a Member, including in respect of distributions made pursuant to Section 5.2 or Section 5.3, and, for the avoidance of doubt, the amount of any such distribution or other payment to a Member shall be net of any such withholding. To the extent that any amounts are so withheld and paid over, such amounts shall be treated as paid to the Person(s) in respect of which such withholding was made. For all purposes under this Agreement, any amounts withheld or paid with respect to a Member pursuant to this Section 10.5 shall offset any distributions to which such Member is entitled concurrently with such withholding or payment and shall be treated as having been

distributed to such Member pursuant to Section 5.2 or Section 5.3 at the time such offset is made. To the extent that the cumulative amount of such withholding or payment exceeds the distributions to which such Member is entitled concurrently with such withholding or payment, the amount of such excess shall be promptly paid to the Company by the Member on whose behalf such withholding is required to be made; provided, however, that any such payment shall not be treated as a Capital Contribution and shall not reduce the amount that a Member is otherwise obligated to contribute to the Company. To the extent that a Member claims to be entitled to a reduced rate of, or exemption from, a withholding Tax pursuant to an applicable income Tax treaty, or otherwise, such Member shall furnish the Company with such information and forms as such Member may be required to complete where necessary to comply with any and all Laws and regulations governing the obligations of withholding Tax agents, and the Company shall apply such reduced rate of, or exemption from, withholding Tax as reflected on such information and forms that have been provided by such Member. Each Member agrees that if any information or form provided pursuant to this Section 10.5 expires or becomes obsolete or inaccurate in any respect, such Member shall update such form or information.

Section 1.6Certain Representations and Warranties. Each Member represents and warrants that any such information and forms furnished by such Member shall be true and accurate and agrees to indemnify the Company from any and all damages, costs and out-of-pocket expenses resulting from the filing of inaccurate or incomplete information or forms relating to such withholding Taxes.

Section 1.1Liability; Member Duties. The debts, obligations and liabilities of the Company, whether arising in contract, tort or otherwise, shall be solely the debts, obligations and liabilities of the Company, and no Covered Person shall be obligated personally for any such debt, obligation or liability of the Company solely by reason of being a Covered Person. Each Member acknowledges and agrees that each Member, in its capacity as a Member, may decide or determine any matter subject to the approval of such Member pursuant to any provision of this Agreement in the sole and absolute discretion of such Member, and in making such decision or determination such Member shall have no duty, fiduciary or otherwise, to any other Member or to the Company Group, it being the intent of all Members that such Member, in its capacity as a Member, has the right to make such determination solely on the basis of its own interests.

Section 1.2Exculpation. To the fullest extent permitted by applicable Law, no Covered Person shall be liable to the Company or any other Covered Person for any loss, damage or claim incurred by reason of any act or omission performed or omitted by such Covered Person in good faith on behalf of the Company and in a manner reasonably believed to be within the scope of the authority conferred on such Covered Person by this Agreement, except that a Covered Person shall be liable for any such loss, damage or claim incurred by reason of such Covered Person’s fraud or willful misconduct.

Section 1.3Indemnification

. The Company shall indemnify, defend and hold harmless any Person who was or is a party or is threatened to be made a party to any threatened, pending or completed actions, suits or proceedings by reason of the fact that such Person is or was a Director or officer of the Company, or is or was a Director or officer of the Company serving at the request of the Company as a director, officer or agent of another limited liability company, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ and experts’ fees), judgments, settlements, penalties and fines actually and reasonably incurred by him or her in connection with the defense or settlement of such, action, suit or proceeding if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the Company; and, with respect to any criminal action or proceeding, either he or she had reasonable cause to believe such conduct was lawful or no reasonable cause to believe such conduct was unlawful; provided, however, for the avoidance of doubt, this Section 11.3 shall not apply with respect to any such actions between the Company and such Person or pursuant to claims under the PSA.

Section 1.4Authorization

. To the extent that such present or former Director or officer of the Company has been successful, on the merits or otherwise, in the defense of any action, suit or proceeding referred to in Section 11.3, or in the defense of any claim, issue or matter therein, the Company shall indemnify him or her against expenses (including attorneys’ fees) actually and reasonably incurred by him or her in connection therewith. Any other indemnification under Section 11.3 shall be made by the Company only as authorized in the specific case, upon a determination that indemnification of the present or former Director or officer is permissible in the circumstances because such present or former Director or officer has met the applicable standard of conduct. Such determination shall be made, with respect to a Person who is a Director or officer at the time of such determination, (a) by a majority vote of the Directors who are not parties to such action, suit or proceeding, even with less than a quorum, or (b) if there are no such Directors, or if such Directors so direct, by independent legal counsel in a written opinion, or (c) by the NiSource Member and the BIP Investor Member. Such determination shall be made, with respect to former Directors and officers, by any Person or Persons having the authority to act on the matter on behalf of the Company.

Section 1.5Reliance on Information

. For purposes of any determination under Section 11.3, a present or former Director or officer of the Company shall be deemed to have acted in good faith and have otherwise met the applicable standard of conduct set forth in Section 11.3 if his or her action is based on the records or books of account of the Company or on information supplied to him or her by a Director or an officer of the Company in the course of his or her duties, or on the advice of legal counsel for the Company or on information or records given or reports made to the Company by an independent certified public accountant or by an appraiser or other expert selected with reasonable care by the Company. The provisions of this Section 11.5 shall not be deemed to be exclusive or to limit in any way the circumstances in which a present or former Director or officer of the Company may be deemed to have met the applicable standard of conduct set forth in Section 11.3.

Section 1.6Advancement of Expenses. Expenses (including reasonable attorneys’ fees) incurred by the present or former Director or officer of the Company in defending any civil, criminal, administrative or investigative action, suit or proceeding may be paid by the Company as authorized in the specific case in the same manner described in Section 11.4, upon receipt of a written affirmation of the present or former Director or officer that he or she has met the standard of conduct described in Section 11.3 and upon receipt of a written undertaking by or on behalf of him or her to repay such amount if it shall ultimately be determined that he or she did not meet the standard of conduct, and a determination is made that the facts then known to those making the determination shall not preclude indemnification under this Article XI.

Section 1.7Non-Exclusive Provisions. The indemnification and advancement of expenses provided by, or granted pursuant to, this Article XI shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled. The Company hereby acknowledges that certain of its Directors and certain of its Members and the direct and indirect partners therein or owners thereof (the “Fund Indemnitees”) may have rights to indemnification, advancement of expenses and/or insurance with respect to their service on the Board (collectively, the “Fund Indemnitors”). The Company hereby agrees: (a) that it is the indemnitor of first resort (i.e., its obligations to the Fund Indemnitees are primary and any obligation of the Fund Indemnitors to advance expenses or to provide indemnification for the same expenses or liabilities incurred by the Fund Indemnitees are secondary) and (b) that it irrevocably waives, relinquishes and releases the Fund Indemnitors from any and all claims against the Fund Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof, except to the extent that a Fund Indemnitee breaches its undertaking to repay advanced expenses as provided in Section 11.6. The Company further agrees that no advancement or payment by the Fund Indemnitors on behalf of the Fund Indemnitees with respect to any claim for which the Fund Indemnitees have sought indemnification from the Company shall affect the foregoing and that the Fund Indemnitors shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of the Fund Indemnitees against the Company.

Section 1.8Survival of Indemnification and Advancement of Expenses. The indemnification and advancement of expenses provided by, or granted pursuant to, this Article XI shall, unless otherwise

provided when authorized or ratified, continue as to a Person who has ceased to be a Director or officer of the Company and shall inure to the benefit of his or her heirs, executors and administrators.

Section 1.9Limitations. Notwithstanding anything contained in this Article XI to the contrary, the Company shall not be obligated to indemnify any Director or officer (or his or her heirs, executors or personal or legal representatives) or advance expenses in connection with a proceeding (or part thereof) initiated by such Person unless such proceeding (or part thereof) was authorized or consented to by the Board.

Section 1.1Members Representations and Warranties. Each Member hereby represents and warrants, severally and not jointly, to the Company and to the other Member as follows:

(a)Such Member is a company duly organized, validly existing and in good standing under the Laws of its jurisdiction of incorporation or formation, as applicable, with full power and authority to enter into this Agreement and perform all of its obligations hereunder.

(b)The execution and delivery of this Agreement by such Member, and the performance by such Member of its obligations hereunder, have been duly and validly authorized by all requisite action by such Member, and no other proceedings on the part of such Member are necessary to authorize the execution, delivery or performance of this Agreement by such Member.

(c)This Agreement has been duly and validly executed and delivered by such Member, and, assuming that this Agreement is a valid and binding obligation of the other Parties, this Agreement constitutes a valid and binding obligation of such Member, enforceable against such Member in accordance with its terms, except as limited by the application of bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium or other Laws relating to or affecting creditors’ rights or general principles of equity.

(d)The execution and delivery by such Member of this Agreement, and the performance by such Member of its obligations hereunder, does not (i) violate or breach its Organizational Documents, (ii) violate any applicable Law to which such Member is subject or by which any of its assets are bound, or (iii) result in any breach of or constitute a default (or an event that, with notice or lapse of time or both, would become a default) under any Contract to which such Member is a party or by which any of its assets are bound.

(e)Such Member is acquiring its Membership Interests (i) for such Member’s own account and not directly or indirectly for the account of any other Person and (ii) for investment and not with a view to their sale or distribution. Such Member understands that the Membership Interests have not been registered under the Securities Act and may be resold only if registered pursuant to the provisions of the Securities Act or if an exemption from registration is available. Such Member understands that no public market now exists for the Membership Interests and that it is unlikely that a public market will ever exist for the Membership Interests. Such Member understands that its investment in the Company is highly speculative in nature and is subject to a high degree of risk of loss, in whole or in part.

Section 1.1Notices. Except as otherwise expressly provided herein, all notices, demands and other communications to be given or delivered under or by reason of the provisions of this Agreement shall be in writing and shall be deemed to have been given (a) when personally delivered, (b) when transmitted by electronic mail (unless if transmitted after 5:00 p.m. Eastern time or other than on a Business Day, then on the next Business Day) to the address specified below (with confirmation of transmission), (c) when sent by internationally-recognized courier in which case it shall be deemed to have been given at the time of actual recorded delivery, or (d) the third (3rd) Business Day following the day on which the same is sent by certified or registered mail, postage prepaid, in each case, to the

This Agreement and all of the provisions hereof shall be binding upon and inure to the benefit of the Parties and their respective successors and permitted assigns; provided, that no Member, nor the Company, shall purport to assign or Transfer all or any of its rights or obligations under this Agreement nor grant, declare, create or dispose of any right or interest in this Agreement in whole or in part except with respect to a Transfer in accordance with the terms of this Agreement, and any attempted or purported assignment hereof not in accordance with the terms hereof shall be void ab initio.

Section 1.3Waiver of Partition. Each Member hereby waives any right to partition of the Company property.

Section 1.4Further Assurances. From and after the Effective Date, from time to time, as and when requested by any Party and at such Party’s expense, any other Party shall execute and deliver, or cause to be executed and delivered, all such documents and instruments and shall take, or cause to be taken, all such further or other actions as such requesting Party may reasonably deem necessary or desirable to carry out the purposes and intent of this Agreement.

Section 1.5Third Party Beneficiaries. Except as otherwise expressly provided herein, nothing expressed or referred to in this Agreement shall be construed to give any Person other than the Parties any legal or equitable right, remedy or claim under or with respect to this Agreement or any provision of this Agreement; provided, that Covered Persons are express third party beneficiaries of Article XI.

Section 1.6Parties in Interest; Non-Recourse. This Agreement shall inure to the benefit of, and be binding upon, the Parties and their respective successors, legal representatives and permitted assigns. This Agreement may only be enforced against, and any claim, action, suit, proceeding or investigation based upon, arising out of or related to this Agreement may only be brought against, the Persons that are expressly named as Parties to this Agreement. Except to the extent named as a Party to this Agreement, and then only to the extent of the specific obligations of such Parties set forth in this Agreement, no past, present or future shareholder, member, partner, manager, director, officer, employee, Affiliate (without giving effect to the proviso set forth in the definition thereof), agent or advisor of any Party shall have any liability (whether in contract, tort, equity or otherwise or by or through theories of equity, agency, control, instrumentality, alter ego, domination, sham, single business enterprise, piercing the veil, undercapitalization or any other attempt to avoid or disregard the entity form of any Person not a Party) for any of the representations, warranties, covenants, agreements or other obligations or liabilities of any of the Parties or for any claim, action, suit, proceeding or investigation based upon, arising out of or related to this Agreement. Notwithstanding anything contained herein, in no event shall this Section 13.6 limit in any way or waive any rights the Company or the NiSource Member may have with respect to the Equity Commitment Letter.

Section 1.7Severability. If any term, provision, covenant or restriction contained in this Agreement is held by a court of competent jurisdiction or other authority to be invalid, void, unenforceable or against its regulatory policy, the remainder of the terms, provisions, covenants and restrictions contained in this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and, to the extent permitted and possible, any invalid, void or unenforceable term shall be deemed replaced by a term that is valid and enforceable and that comes closest to expressing the intention of such invalid, void or unenforceable term.

Section 1.8Construction. The language used in this Agreement shall be deemed to be the language chosen by the Parties to express their mutual intent, and no rule of strict construction shall be applied against any Person. The headings of the sections and paragraphs of this Agreement have been

inserted for convenience of reference only and shall in no way restrict or otherwise modify any of the terms or provisions hereof.

Section 1.9Complete Agreement. This Agreement (including any schedules thereto), constitutes the entire agreement of the Parties hereto with respect to the subject matter hereof and thereof and supersedes any prior understandings, agreements or representations by or among the Parties hereto or Affiliates thereof, written or oral, to the extent they relate in any way to the subject matter hereof.

Section 1.10Amendment; Waiver. Subject to Article VIII, neither this Agreement nor any other Organizational Document of the Company may be amended (whether by merger or otherwise) except in a written instrument signed by Members owning at least a majority of the Membership Interests; provided, that (a) the prior written consent of any Member shall be required in respect of any such proposed modification, alteration, supplement or amendment that would have a material disproportionate adverse impact on that Member (in its capacity as a Member) as compared to the other Members (in their capacity as Members) and (b) notwithstanding anything in this Agreement to the contrary, Article V, Article VI, Article VII, Article VIII and this Section 13.10 may not be amended other than by a written instrument signed by the BIP Investor Member. In the event that the Company issues Membership Interests to one or more Third Parties pursuant to Section 5.1(c) or Section 7.1, the Members and the Company shall negotiate in good faith to amend this Agreement to the extent reasonably necessary to reflect such additional Members. Any amendment or revision to Schedule 1 that is made by an officer solely to reflect information regarding Members or the Transfer or issuance of Membership Interests made in accordance with the terms of this Agreement shall not be considered an amendment to this Agreement and shall not require any Board or Member approval. Any failure or delay on the part of any Party in exercising any power or right hereunder shall not operate as a waiver thereof, nor shall any single or partial exercise of any such right or power preclude any other or further exercise thereof or the exercise of any other right or power hereunder or otherwise available at law or in equity.

Section 1.11Governing Law. This Agreement, and any claim, action, suit, investigation or proceeding of any kind whatsoever, including a counterclaim, cross-claim or defense, regardless of the legal theory under which such liability or obligation may be sought to be imposed, whether sounding in contract or tort, or whether at law or in equity, or otherwise under any legal or equitable theory, that may be based upon, arising out of or related to this Agreement or the negotiation, execution or performance of this Agreement or the transactions contemplated hereby shall be governed by and construed in accordance with the internal Laws of the State of Delaware applicable to agreements executed and performed entirely within such State without regards to conflicts of law principles of the State of Delaware or any other jurisdiction that would cause the Laws of any jurisdiction other than the State of Delaware to apply.

Section 1.12Specific Performance

. The Parties agree that irreparable damage, for which monetary relief, even if available, shall not be an adequate remedy, would occur in the event that any provision of this Agreement is not performed in accordance with its specific terms or is otherwise breached. It is accordingly agreed that (a) the Parties shall be entitled to seek an injunction or injunctions, specific performance or other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof without proof of damages or otherwise, this being in addition to any other remedy to which they are entitled under this Agreement, and (b) the right of specific performance and other equitable relief is an integral part of this Agreement and the business and legal understandings among the Members with respect to the Company, and without that right, none of the Members would have entered into this Agreement. The Parties acknowledge and agree that any Party pursuing an injunction or injunctions or other Order to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in accordance with this Section 13.12 shall not be required to provide any bond or other security in connection with any such Order. The remedies available to the Parties pursuant to this Section 13.12 shall be in addition to any other remedy to which they may be entitled at law or in equity, and the election to pursue an injunction or specific performance shall not restrict, impair or otherwise limit any Party from seeking to collect or collecting damages. Each of the Parties agrees that it shall not oppose the granting of an injunction, specific performance and other equitable relief on the basis that any other Party has an adequate remedy at law or that any award of specific performance is not an appropriate remedy for any reason at law or in equity.

Section 1.13Escalation; Arbitration.

(a)In connection with any dispute, controversy or claim among the Members relating to or arising out of this Agreement, the Members will use their reasonable efforts to resolve such dispute within thirty (30) days. If the dispute has not been resolved within such thirty (30) day period, the Members will escalate the dispute to the respective Senior Officers, who will meet to discuss and use their reasonable efforts to resolve the dispute. If the Members remain unable to resolve the dispute within thirty (30) days of the initial meeting of the Senior Officers or such later date as the Members subject to such dispute may agree, such dispute shall be finally settled by binding arbitration administered by the American Arbitration Association (“AAA”) utilizing its Commercial Arbitration Rules in effect as of the date the arbitration is commenced. The arbitration shall be conducted before a single arbitrator, if the Parties can agree on the one arbitrator. If the Parties cannot agree on a single arbitrator, there shall be a panel of three arbitrators with one chosen by the BIP Investor Member, one chosen by the NiSource Member, and the third arbitrator selected by the two Members-appointed arbitrators. If a Party fails to appoint an arbitrator within 30 days following a written request by another Party to do so or if the two party-appointed arbitrators fail to agree upon the selection of a third arbitrator, as applicable, within 30 days following their appointment, the additional arbitrator shall be selected by the AAA pursuant to its applicable procedures. Each arbitrator shall be disinterested and have at least 20 years of experience with commercial matters. The arbitrator(s) shall have the power to award any appropriate remedy consistent with the objectives of the arbitration and subject to, and consistent with, all Laws and Orders applicable to the Company and its Subsidiaries (including, for the avoidance of doubt, the necessity of obtaining any requisite authorization, approval or consent of any Governmental Body necessary to implement the appropriate remedy). The decision of the one arbitrator or, if applicable, the majority of the three arbitrators shall be final and binding upon the Parties (subject only to limited review as required by applicable Law). Judgment upon the award of the arbitrator(s) may be entered in any court of competent jurisdiction or otherwise enforced in any jurisdiction in any manner provided by applicable Law. The losing Party shall pay the prevailing Party’s attorney’s fees and costs and the costs associated with the arbitration, including expert fees and costs and the arbitrators’ fees and costs; provided, however, that each Party shall bear its own fees and costs until the arbitrator(s) determine which, if any, Party is the prevailing Party and the amount that is due to such prevailing Party. The arbitration proceedings shall take place in Chicago, Illinois and, for the avoidance of doubt, the arbitration proceedings shall be conducted in the English language.

(b)All discussions, negotiations and proceedings under this Section 13.13, and all evidence given or discovered pursuant hereto, will be maintained in strict confidence by all Parties, except where disclosure is required by applicable Law, necessary to comply with any legal requirements of such Party or necessary or advisable in order for a Party to assert any legal rights or remedies, including the filing of a complaint with a court or, based on the advice of counsel, such disclosure is determined to be necessary or advisable under applicable securities Laws or the rules of any stock exchange on which any of such Party’s securities are traded. Disclosure of the existence of any arbitration or of any award rendered therein may be made as part of any action in court for interim or provisional relief or to confirm or enforce such award.

(c)Any settlement discussions occurring and negotiating positions taken by any Party in connection with the procedures under this Section 13.13 will be subject to Rule 408 of the Federal Rules of Civil Procedure and shall not be admissible as evidence in any proceeding relating to the subject matter of this Agreement.

(d)The fact that the dispute resolution procedure specified in this Section 13.13 has been or may be invoked will not excuse any Party from performing its obligations under this Agreement, and during the pendency of any such procedure, all Parties must continue to perform their respective obligations in good faith. In addition, in no event shall the fact that this provision has been invoked and the pendency of the proceedings limit, suspend, delay or waive any other rights and remedies provided in this Agreement to any Member.

(e)Notwithstanding the agreement to arbitrate contained in this Section 13.13, in the event that either Party wishes to seek a temporary restraining order, a preliminary or temporary injunction, or other injunctive relief in connection with any claim, demand, cause of action, dispute, controversy, or

other matter arising out of or relating to this Agreement or the alleged breach thereof, whether such claim sounds in contract, tort, or otherwise, at law or in equity, under state or federal law, whether provided by statute or the common law, each Party shall have the right to pursue such injunctive relief in court, rather than by arbitration. The Parties agree that such action for a temporary restraining order, a preliminary or temporary injunction, or other injunctive relief may be brought in the state or federal courts of Delaware, or in any other forum in which jurisdiction is appropriate.

Section 1.14Counterparts. This Agreement may be executed in counterparts, and any Party may execute any such counterpart, each of which when executed and delivered shall be deemed to be an original and all of which counterparts taken together shall constitute one and the same instrument. This Agreement shall become effective when each Party shall have received a counterpart hereof signed by the other Parties. The Parties agree that the delivery of this Agreement may be effected by means of an exchange of facsimile or electronically transmitted signatures.

Section 1.15Fair Market Value Determination

. In the event the Board makes a determination of Fair Market Value under this Agreement, upon request by the NiSource Member or the BIP Investor Member, so long as such Member holds a Percentage Interest (or, with respect to the BIP Investor Member, the Investor Members collectively hold an aggregate Percentage Interest) greater than 5%, within five Business Days after receiving written notice of the Board’s determination in connection with any determination of Fair Market Value of Membership Interests or other assets under this Agreement (which determination shall be provided by the Company to each Member promptly following the making thereof), the Company shall select a nationally recognized independent valuation firm with no existing or prior business or personal relationship with any Member or any of its Affiliates in the three year period immediately preceding the date of engagement, pursuant to this Section 13.15 (the “Independent Evaluator”) to determine such Fair Market Value. Each of the Company and the requesting Member shall submit their view of the Fair Market Value of the Membership Interests or the relevant asset(s) to the Independent Evaluator, and each party will receive copies of all information provided to the Independent Evaluator by the other party. The final Independent Evaluator’s determination of the Fair Market Value of such Membership Interests or asset(s) shall be set forth in a detailed written report addressed to the Company and the Members within 30 days following the Company’s selection of such Independent Evaluator and such determination shall be final, conclusive and binding. In rendering its decision, the Independent Evaluator shall determine which of the positions of the Company and the requesting Member submitted to the Independent Evaluator is, in the aggregate, more accurate (which report shall include a worksheet setting forth the material calculations used in arriving at such determination), and, based on such determination, adopt either the Fair Market Value determined by the Company or the requesting Member. Any fees and expenses of the Independent Evaluator incurred in resolving the disputed matter(s) will be borne by the party whose positions were not adopted by the Independent Evaluator. Notwithstanding the foregoing, the Board’s determination of Fair Market Value under this Agreement shall be conclusive and relied upon by the Members in carrying out their obligations hereunder, unless and until the Independent Evaluator determines otherwise. The pendency of this process shall not excuse the performance of any obligations of a Member hereunder.
