Article I
TRANSFERS OF MEMBERSHIP INTERESTS

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 Investor Member may Transfer any of its Membership Interests to any Person prior to the date that is the seventh (7th) anniversary of the Effective Date (the “Lock-Up Period”) other than with the prior written consent of the NiSource Member. After the expiration of the Lock-Up Period, each Investor Member, as applicable, may Transfer its Membership Interests in accordance with this Article VI. Notwithstanding the forgoing, each Investor Member 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.

(e)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 Member 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

Exhibit 10.1

(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)

(A)If the Investor Member is the Transferring Member, the Investor Member shall first deliver to the Non-Transferring Member a written notice which shall be a binding offer (an “Investor Sale Notice”) setting forth the cash price and all other material terms and conditions at which the Investor 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 Investor Sale Notice shall be firm, not subject to withdrawal, and prepared and delivered in good faith. Within ninety (90) days following its receipt of an Investor Sale Notice, the Non-Transferring Member may accept the Investor 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 Investor 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.

(B)If the NiSource Member is the Transferring Member, the NiSource Member shall first deliver to the Non-Transferring Member a written right of first offer notice (a “NiSource Sale Notice”) describing the Subject Membership Interests and setting forth all other material terms and conditions (other than the cash price) upon which the NiSource Member is willing to sell the Subject Membership Interests to the Non-Transferring Member. The NiSource Sale Notice shall not be a binding offer and need not include a price. Within ninety (90) days following its receipt of a NiSource Sale Notice, the Investor Member (as the Non-Transferring Member) may deliver to the NiSource Member a written response setting forth the cash price and confirming the other material terms and conditions specified in the NiSource Sale Notice (the “Investor Offer”). The Investor Offer shall be a binding offer by the Investor Member to purchase the Subject Membership Interests on the terms set forth therein, shall be firm, not subject to withdrawal, and prepared and delivered in good faith, and shall remain open for acceptance by the NiSource Member for a period of ninety (90) days following the

Exhibit 10.1

NiSource Member’s receipt thereof. The NiSource Member may accept the Investor Offer within such ninety (90)-day period, 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. If the NiSource Member does not accept the Investor Offer within such ninety (90)-day period, the Investor Offer shall be deemed rejected and shall terminate without further action by any party.

(ii)If the NiSource Member does not accept the offer made pursuant to the Investor Sale Notice or the Investor Offer within such ninety (90)-day period (or if the Investor Member does not make an Investor Offer within ninety (90) days following receipt of a NiSource Sale Notice), then the Transferring Member will, for a period of one hundred eighty (180) days commencing on the earlier of (A) the expiration of such ninety (90)-day period (or ninety (90) -day period if the Investor Member does not make an Investor Offer) and (B) the delivery of a written notice by the NiSource Member to the Investor Member rejecting the offer set forth in the Investor Sale Notice or Investor Offer, as applicable, (if any) (such one hundred eighty (180)-day period, the “Sale Period”), be entitled to sell the Subject Membership Interests to any one Third Party for (x) in the case of the NiSource Member being the Transferring Member, at any higher price than the price set forth in the Investor Offer (or at any price if the Investor Member does not make an Investor Offer) and (y) in the case of the Investor Member being the Transferring Member, at a price greater than one hundred and seven and a half percent (107.5%) of the price set forth in the Investor Sale Notice (the “Threshold Price”) and upon other terms and conditions (excluding price) that are not more favorable to the acquiror than those specified in the Investor Sale Notice or Investor Offer, as applicable, subject to the other terms of this Section 6.3 (including Section 6.3(e)); provided, that, to the extent the Investor Member receives a price lower than the Threshold Price, the Investor Member will offer to sell such Subject Membership Interests at the offered price to the NiSource Member and the NiSource Member shall have thirty (30) days to accept such offer; provided, if the NiSource Member does not accept such offer or respond in that period, then the Investor Member may sell the Subject Membership Interests to the third party at the revised price that is below the Threshold Price. 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 Investor Sale Notice or NiSource Sale Notice, as applicable, 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 of each 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

Exhibit 10.1

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).

(e)Any sale by the Transferring Member to the Non-Transferring Member, pursuant to Section 6.3(a) shall be consummated pursuant to a membership interest purchase agreement which shall contain representations and warranties by the Transferring Member to the Non-Transferring Member that (i) the Transferring Member has full right, title and interest in and to the Subject Membership Interests, (ii) 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, (iii) 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 and (iv) other customary representations and warranties.

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,

Exhibit 10.1

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)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.

Exhibit 10.1

(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.

Exhibit 10.1

(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.

Article II
PREEMPTIVE RIGHTS

Section 2.1Preemptive 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.

(b)Notwithstanding anything in Section 9.8(a) or this Agreement to the contrary, the cooperation requested by either Investor Member pursuant to Section 9.8(a) shall not (i) unreasonably interfere with the ongoing operations of the NiSource Member or its Subsidiaries, or (ii) require the NiSource Member or any of its Subsidiaries (other than the Company) to (A) pay any commitment or other similar fee, (B) have or incur any liability or obligation in connection with any Debt Financing, including under any agreement or any document related to any Debt Financing, other than any such documents that are customary in connection with such Debt Financing as set forth in Section 9.8(a), (C) commit to taking any action (including entering into any Contract) or to otherwise execute any definitive agreement in connection with any Debt Financing, or (D) take any action that would conflict with, violate or breach or result in a violation or breach of or default under any Contract, this Agreement or any other document contemplated hereby or any Law or regulatory requirements. In no event shall the Company or NiSource Member be required to provide information relating to the transactions contemplated hereby or with any other Person in connection with any possible sale or transfer of assets or equity of the Company and its Subsidiaries, any information subject to the attorney-client privilege or any confidential or sensitive information, or relating to any Tax Return; provided, that, the Company and NiSource Member will use commercially reasonable efforts to redact such materials to remove any such confidential or sensitive information to provide to the Investor Member.

Exhibit 10.1

Section 4.9Credit Support. For so long as there are (a) any guarantees, credit support, letters of credit or financial assurances of a member of the Outside Group related to support obligations of the Company Group, each Member shall pay the portion equal to its Percentage Interest of any payment or draw request on such credit support facilities on or before the applicable payment date required or (b) any guarantees, credit support, letters of credit or financial assurances of the Company or any of its Subsidiaries related to support obligations of a member of the Outside Group, the NiSource Member shall pay all such payments on or before the applicable payment date required. If a Member does not make a payment in accordance with the above, the Company may issue a Capital Call Request Notice in accordance with Section 5.1 for such amount from the applicable Member. For the avoidance of doubt, the failure to make the payment in clauses (a) or (b) prior to a Capital Call Request Notice shall not be an Event of Default and the failure to fund pursuant to a Capital Call Request Notice shall be treated in accordance with Section 5.1. Notwithstanding the foregoing, if the VCOC Investor Member fails to make its payment in accordance with this Section 9.9, the BIP Investor Member shall be obligated to make such payment.

Article V
TAX MATTERS

Section 5.1Tax Classification. The Parties intend that the Company be classified as a partnership for U.S. federal income (and applicable state and local) Tax purposes. Without limiting Section 8.1(a), neither the Company nor any Member shall make any election to change the tax classification of the Company or otherwise take any action inconsistent with such intended tax classification without the consent of the Board (or its designee).

Section 5.2Partnership Representative.

(a)The NiSource Member is hereby designated the “Partnership Representative” within the meaning of Code Section 6223(a) of the Company. The Partnership Representative shall, if required, designate from time to time a “designated individual” to act on behalf of the Partnership Representative, and such designated individual shall be subject to replacement by the Partnership Representative in accordance with the Code and Treasury Regulations. If any state or local tax law provides for a tax matters partner, partnership representative, or person having similar rights, powers, authority, or obligations, the Partnership Representative shall also serve in such capacity. The Partnership Representative is authorized to represent the Company before the Internal Revenue Service and any other governmental agency with jurisdiction, make all decisions regarding permitted elections under the Code, Treasury Regulations, and other state and local tax law with respect to tax proceedings; provided, however, the Partnership Representative shall not enter into any settlement or similar agreement without the consent of the Board (such consent not to be unreasonably withheld, conditioned, or delayed). All Members (and former Members) agree to cooperate with, and to do and refrain from doing any or all things reasonably required by the Partnership Representative in connection with the conduct of all such proceedings or to otherwise allow the Company and the Partnership Representative to comply with the partnership audit provisions of the Code, Treasury Regulations, and similar state and local law. 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

Exhibit 10.1

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 5.3Tax 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)To the extent permitted by law, to elect to apply the de minimis safe harbor under Treasury Regulations Section 1.263(a)-1(f);

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

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

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

Section 5.4Cooperation. 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

Exhibit 10.1

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 5.5Withholding. 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 5.6Certain 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.

Article VI
LIABILITY; EXCULPATION; INDEMNIFICATION

Section 6.1Liability; 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 6.2Exculpation. 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 6.3Indemnification. 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

Exhibit 10.1

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.

Section 6.4Authorization. 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 6.5Reliance 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 6.6Advancement 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 6.7Non-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 6.8Survival 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.

Exhibit 10.1

Section 6.9Limitations. 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 7.2Members Representations and Warranties. As of the Effective Date, 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 limited liability company or limited partnership duly organized, validly existing and in good standing under the Laws of its jurisdiction of organization or formation, as applicable, with full power and authority to enter into this Agreement and perform all of its obligations hereunder.

Section 8.11Governing 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 8.12Specific 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.

Section 8.13Escalation; 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.

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 8.14Counterparts. 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.

Exhibit 10.1

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.
