 SERVICES

 SECTION 2.1 Provision of Services. Subject to the terms and conditions of this Agreement, Columbia Services shall
provide, or cause to be provided, to the NiSource Parties, solely for the benefit of the NiSource Business in the ordinary course of business, the services described on Schedule A (the “Services”), the terms of which are
incorporated herein by reference. No NiSource Party shall resell, subcontract, license, sublicense or otherwise transfer any of the Services to any Person whatsoever or permit use of any of the Services by any Person other than by the NiSource
Parties directly in connection with the conduct of the NiSource Business in the ordinary course of business. Columbia Services shall exercise reasonable care to ensure that the manner in which it performs or provides the Services does not have any
adverse effect on the name, trading image, goodwill or business of any NiSource Party.

Services. If, after the execution of this Agreement and prior to the date that is two months from the date hereof, NiSource Services and Columbia Services determine that a service provided by or to the NiSource Business as conducted by

added to this Agreement, it being agreed that Columbia Services’ compensation for such services shall be determined in accordance with Section 3.1; provided, however, Columbia Services shall not be required to provide

operation of its business or (z) the parties are unable to reach agreement on the terms and conditions applicable to such additional services. If the parties agree on the specific terms and conditions applicable to such services, the parties
shall execute an amendment to this Agreement that provides for the substitution of Schedule A, or additions or supplements to Schedule A, in order to describe such service and the agreement upon the related fees and other specific
terms and conditions applicable thereto.

 SECTION 2.3 Standard of Performance; Priority. 

(a) Columbia Services shall use commercially reasonable efforts to provide, or cause to be provided, to the NiSource Parties, each Service in
a manner generally consistent with the manner and level of care with which such Service was provided to the NiSource Parties immediately prior to the Distribution Date (or, with respect to any Service not provided by any Columbia Party to any
NiSource Party prior to the Distribution Date, generally consistent with the manner and level of care with which such Service is performed by any Columbia Party on behalf of any other Columbia Party), unless otherwise specified in this Agreement or
Schedule A. Notwithstanding the foregoing, Columbia Services shall have no obligation hereunder to provide to any NiSource Party (i) any improvements, upgrades, updates, substitutions, modifications or enhancements to any of the
Services unless otherwise specified on Schedule A or (ii) any Service to the extent that the need for such Service arises, directly or indirectly, from the acquisition by any NiSource Party, outside the ordinary course of business, of
any assets of, or any equity interest in, any Person. 
 (b) Columbia Services shall use commercially reasonable efforts not to establish
priorities in favor of the Columbia Parties, on the one hand, and to the detriment of the NiSource Parties, on the other hand, as to the provision of any Service solely based on the fact that the NiSource Parties are no longer affiliated with
Columbia Services, and Columbia Services shall use commercially reasonable efforts to provide the Services, or cause the Services to be provided, within a time frame so as not to materially disrupt the NiSource Business. Notwithstanding the
foregoing, NiSource Services acknowledges and agrees that one or more of the Columbia Parties may be providing to other Columbia Parties services similar to the Services provided hereunder, or services that involve the same resources as those used
to provide the Services, and that Columbia Services shall have the right to establish reasonable priorities as between the NiSource Parties, on the one hand, and the Columbia Parties, on the other hand, as to the provision of any Service if Columbia
Services determines that such priorities are necessary to avoid any adverse effect on any of the Columbia Parties. If any such priorities are established, Columbia Services shall advise NiSource Services as soon as reasonably possible of any
Services that will be delayed as a result of such prioritization and will use commercially reasonable efforts to minimize the duration and impact of such delays. 

(c) Unless otherwise specifically set forth on Schedule A, the NiSource Parties’ use of the Services shall be consistent with past
practice. 
 (d) Notwithstanding anything to the contrary contained herein, in no event shall: 

(i) any Service include any service that would be or otherwise becomes unlawful for Columbia Services to provide; 

(ii) Columbia Services be obligated to exercise business judgment or general management for any NiSource Party or make any regulatory
decisions on behalf of any NiSource Party as part of providing the Services; 
 (iii) Columbia Services be obligated to breach or violate
any agreement or license in connection with providing the Services, including any software agreement or license, it 

  
 3 








 
being agreed that the provision of any agreements, software licenses, software tools, software or other assets in connection with providing the Services shall be subject to the terms of any
related agreements or licenses; or 
 (iv) Columbia Services be obligated to copy or provide any information or documents subject to any
attorney client privilege or containing commercially sensitive information relating to any Columbia Party in connection with providing the Services. 

(e) SUBJECT TO THE FOREGOING, NISOURCE SERVICES ACKNOWLEDGES AND AGREES THAT COLUMBIA SERVICES MAKES NO REPRESENTATIONS OR WARRANTIES
(INCLUDING WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE) OR GUARANTEES OF ANY KIND, EXPRESS OR IMPLIED, WITH RESPECT TO ANY SERVICES PROVIDED HEREUNDER AND THAT THE SERVICES TO BE PROVIDED HEREUNDER ARE FURNISHED “AS
IS,” WHERE IS, WITH ALL FAULTS. 
 SECTION 2.4 Columbia Services Employees Performing Services. Notwithstanding anything
to the contrary contained in Section 2.1 (but subject to the last sentence of this Section 2.4), Columbia Services shall have the exclusive right to select, employ, pay, supervise, administer, direct and discharge any of its
employees who perform the Services. Columbia Services shall be responsible for paying such employees’ compensation and providing to such employees any benefits. With respect to each Service, Columbia Services shall use commercially reasonable
efforts to have qualified individuals participate in the provision of such Service; provided, however, that (a) Columbia Services shall not be obligated to have any individual participate in the provision of any Service if
Columbia Services determines that such participation would adversely affect any Columbia Party and (b) no Columbia Party shall be required to continue to employ any particular individual during the applicable Service Period. 

SECTION 2.5 Compliance with Law. Each party hereto shall, and shall cause each of its Affiliates to, comply with all applicable
laws, rules, ordinances and regulations of any governmental entity or regulatory agency governing the Services to be provided hereunder. Neither party hereto shall take, or permit any of its Affiliates to take, any action in violation of any
applicable law, rule, ordinance or regulation that could result in liability being imposed on the other party hereto or any of such other party’s Affiliates. 

SECTION 2.6 Temporary Nature of Services. NiSource Services acknowledges that the purpose of this Agreement is to enable it to
receive the Services on an interim basis. Accordingly, at all times from and after the Distribution Date, NiSource Services shall use commercially reasonable efforts to (a) make or obtain, or cause to be made or obtained, any filings,
registrations, approvals, permits or licenses; (b) implement, or cause to be implemented, any systems; (c) purchase, or cause to be purchased, any equipment; and (d) take, or cause to be taken, any and all other actions, in each case
necessary or advisable to enable NiSource Services or an Affiliate thereof to provide the Services for the relevant NiSource Parties as soon as reasonably practicable, and in any event prior to the expiration of the relevant Service Periods. For the
avoidance of doubt, NiSource Services acknowledges and agrees that Columbia Services shall not be required to provide any Service for a period longer than the applicable Service Period.

 ARTICLE III 

FEES AND PAYMENTS 

SECTION 3.1 Fees for the Services. 

(a) As compensation for the Services, NiSource Services agrees to pay Columbia Services, in accordance with this Agreement, amounts equal to
(i) Columbia Services’ reasonable estimate of its actual costs in connection with the performance of the Services pursuant to this Agreement and, if applicable, consistent with the prices Columbia Services would charge to an Affiliate, in
each case without taking into account any profit margin or projected savings from increased efficiency, plus (ii) Columbia Services’ reasonable and customary out-of-pocket expenses incurred in connection with the performance of the
Services pursuant to this Agreement. 
 (b) Schedule B sets forth for each month during the term of this Agreement the parties’
initial determination of the amounts payable for the Services pursuant to Section 3.1(a) (excluding any Services provided by third-party service providers). Such amounts are set forth by type of Services involved: Information
Technology, Finance, Human Resources and Supply Chain (each such type, a “Function”). The amounts set forth on Schedule B are subject to adjustment as follows: 

(i) Columbia Services will use commercially reasonable efforts to track its costs and expenses of providing such Services per Function in
order to determine whether during each of the six month periods ended December 31, 2015, June 30, 2016 and December 31, 2016 the amounts set forth on Schedule B with respect to any Function differ from the amounts required
to be paid pursuant to Section 3.1(a) with respect to such Function. 
 (ii) In the event that pursuant to
Section 3.1(b)(i) NiSource Services and Columbia Services determine that for any six month period ended December 31, 2015, June 30, 2016 or December 31, 2016, as the case may be, the amounts set forth on
Schedule B with respect to any Function differ from the amounts required to be paid pursuant to Section 3.1(a) with respect to such Function by an amount equal to the greater of 10% or $100,000 in the aggregate, then NiSource
Services and Columbia Services shall adjust the monthly amounts set forth on Schedule B for the months following such dates, as applicable, to reflect the amounts required to be paid pursuant to Section 3.1(a) in light of such
determination. Such adjustment shall be in a writing executed by both parties. 
 SECTION 3.2 Invoices. 

(a) Columbia Services shall submit statements of account to NiSource Services within fifteen (15) days after the end of each month with
respect to all amounts payable by NiSource Services to Columbia Services hereunder (the “Invoiced Amount”), setting out the amount payable to Columbia Services as a result of providing such Services (together with, in arrears, any
Commingled Invoice Statements (as defined below) and any other invoices for Services provided by third parties that have not been issued by such third parties to NiSource Services as contemplated by Section 3.2(b), in each case setting
out the Services provided by the applicable third parties by reference to Schedule A). 

  
 5 








 (b) Columbia Services may cause any third-party service provider to which amounts are payable by
or for the account of NiSource Services in connection with the Services to issue a separate invoice to NiSource Services for such amounts. NiSource Services shall pay or cause to be paid any such separate third-party invoice in accordance with the
payment terms thereof. Any third-party invoices that aggregate Services for the benefit of the NiSource Parties, on the one hand, with services not for the benefit of the NiSource Parties, on the other hand (each, a “Commingled
Invoice”), shall be separated by Columbia Services. Columbia Services shall prepare a statement indicating that portion of the invoiced amount of such Commingled Invoice that is attributable to Services rendered for the benefit of the
NiSource Parties (the “Commingled Invoice Statement”). As promptly as practicable after the preparation thereof, Columbia Services shall deliver such Commingled Invoice Statement and a copy of the Commingled Invoice to NiSource
Services. Columbia Services shall not be required to use its own funds for payments to any third-party service provider providing any of the Services or to satisfy any payment obligation of any NiSource Party to any third-party service provider;
provided, however, that in the event Columbia Services does use its own funds for any such payments to any third-party service provider, NiSource Services shall reimburse Columbia Services (i) for such payments as invoiced by
Columbia Services within thirty (30) days following the date of delivery of such invoice from Columbia Services plus (ii) interest at the one month LIBOR rate plus 1.275% per annum for such payments from the date paid by Columbia
Services to such third-parties to the date reimbursed by NiSource Services to Columbia Services. 
 SECTION 3.3 Invoice
Disputes. In the event that NiSource Services in good faith disputes an invoice submitted by Columbia Services, NiSource Services may withhold payment of any amount subject to the dispute; provided, however, that
(a) NiSource Services will continue to pay all undisputed amounts in accordance with the terms hereof and (b) NiSource Services will notify Columbia Services, in writing, of any disputed amounts and the reason for any dispute by the due
date for payment of the invoice containing any disputed amounts. In the event of a dispute regarding the amount of any invoice, or portion thereof, the parties hereto will use all reasonable efforts to resolve such dispute within thirty
(30) days after NiSource Services delivers written notification of such dispute to Columbia Services. Each party hereto will provide full supporting documentation concerning any disputed amount or invoice within thirty (30) days after
NiSource Services delivers written notification of the dispute. Unpaid fees that are under good faith dispute will not be considered a basis for default hereunder. To the extent that a dispute regarding the amount of any invoice cannot be resolved
pursuant to this Section 3.3, the dispute resolution procedures set forth in Section 7.1 shall apply. 

SECTION 3.4 Time of Payment. 

(a) Subject to Section 3.4(b), NiSource Services shall pay the Invoiced Amount to Columbia Services in United States dollars by
wire transfer of immediately available funds to an account specified by Columbia Services in the relevant invoice, or in such other manner as specified by Columbia Services in writing, within thirty (30) days after the date of delivery to
NiSource Services of the applicable statement of account; provided, however, that in the event that NiSource Services, in good faith and upon reasonable grounds disputes any invoiced item in accordance with Section 3.3,
payment of such item may be made after resolution of such dispute. 

  
 6 








 (b) In the event that NiSource Services does not make any payment required under the provisions
of this Agreement to Columbia Services when due in accordance with the terms hereof, Columbia Services shall, at its option, charge NiSource Services interest on the unpaid amount at the prime rate as reported by The Wall Street Journal (or its
successor). In addition, NiSource Services shall reimburse Columbia Services for all costs of collection of overdue amounts, including any reimbursement required under Section 3.2(b) and any reasonable attorneys’ fees. 

(c) NiSource Services shall, within thirty (30) days after the date of delivery to NiSource Services of any Commingled Invoice Statement,
pay or cause to be paid the amount set forth on such Commingled Invoice Statement to the third-party service provider and shall concurrently deliver evidence of such payment to Columbia Services. NiSource Services acknowledges and agrees that it
shall be responsible for any interest or other amounts in respect of any portion of any Commingled Invoice that NiSource Services is required to pay pursuant to any Commingled Invoice Statement. 

SECTION 3.5 Taxes. Any amounts payable under this Agreement are exclusive of any goods and services taxes, value added taxes,
sales taxes or similar taxes (collectively, “Sales Taxes”) now or hereinafter imposed on the performance or delivery of Services, and an amount equal to such Sales Taxes so chargeable shall, subject to receipt of a valid receipt or
invoice as required below in this Section 3.5, be paid by NiSource Services to Columbia Services in addition to the amounts otherwise payable under this Agreement. In each case where an amount in respect of Sales Tax is payable by
NiSource Services in respect of a Service provided by any Columbia Party, Columbia Services shall furnish in a timely manner a valid Sales Tax receipt or invoice to NiSource Services in the form and manner required by applicable law to allow
NiSource Services to recover such Sales Tax to the extent allowable under such law. The parties hereto agree to use commercially reasonable efforts to cooperate to minimize any Sales Tax payable with respect to the Services. 

ARTICLE IV 
 TERM AND
TERMINATION 
 SECTION 4.1 Term. The performance of the Services under this Agreement shall commence on the Distribution
Date and shall continue with respect to each Service until the expiration date set forth on Schedule A with respect to such Service as such date may be extended with respect to such Service by mutual agreement of the parties in accordance
with Schedule A (each, a “Service Period”), unless such period is earlier terminated in accordance with the terms hereof. 

SECTION 4.2 Termination by NiSource Services. 

(a) NiSource Services will have no obligation to continue to use any of the Services and, except as otherwise specified on Schedule A,
NiSource Services may terminate any Service by giving Columbia Services at least thirty (30) days’ prior written notice of NiSource Services desire to terminate such Service. To the extent possible, NiSource Services will give such notice
at the beginning of a month to terminate the Service as of the beginning of the next month to avoid the need to prorate any monthly payment charges. As soon as reasonably practicable 

  
 7 








 
following receipt of any such notice, Columbia Services will advise NiSource Services in writing as to whether termination of such Service will (i) require the termination or partial
termination of, or otherwise affect the provision of, any other Services or (ii) result in any early termination costs (which will be limited to costs that Columbia Services actually incurs). If either will be the case, NiSource Services may
withdraw its termination notice within five (5) Business Days after the receipt of such notice from Columbia Services. If NiSource Services does not withdraw the termination notice within such period, such termination will be final. Upon such
termination, NiSource Services’ obligation to pay for such Service(s) will terminate, and Columbia Services will cease, or cause its Affiliates or third-party service providers to cease, providing the terminated Service(s); provided,
however, that NiSource Services shall reimburse Columbia Services for the reasonable termination costs actually incurred by Columbia Services resulting from NiSource Services’ early termination of such Services, including those owed to
third-party service providers. Columbia Services shall use commercially reasonable efforts to mitigate such termination costs. 
 (b)
NiSource Services may terminate this Agreement as of the end of any month provided that (i) NiSource Services has given Columbia Services at least thirty (30) days prior written notice and (ii) NiSource Services reimburses Columbia
Services for any reasonable out-of-pocket expenses or costs actually incurred by Columbia Services due to such termination. 
 SECTION
4.3 Termination for Breach. Either party hereto shall have, in addition to any other rights and remedies such party may have, the right to terminate this Agreement on thirty (30) days’ prior written notice to the other party
hereto, if such other party shall have materially breached or defaulted in the performance of any provision of this Agreement; provided, however, that if it is possible for such breach or default to be cured and the party receiving
such notice of termination shall cure such breach or default within thirty (30) days after receipt of such notice, then this Agreement shall continue in full force and effect. 

SECTION 4.4 Termination for Insolvency. Either party hereto shall have the right, notwithstanding any other provisions of this
Agreement, and in addition to any other rights and remedies such party may have, to terminate this Agreement forthwith and at any time if: (a) the other party hereto becomes insolvent; (b) the other party hereto files a petition in
bankruptcy or insolvency; (c) the other party hereto is adjudicated bankrupt or insolvent; (d) the other party hereto files any petition or answer seeking reorganization, readjustment or arrangement of such other party’s business
under any law relating to bankruptcy or insolvency; (e) a receiver, trustee or liquidator is appointed for any of the property of the other party hereto and within sixty (60) days thereof such other party fails to secure a dismissal
thereof; (f) the other party hereto makes any assignment for the benefit of creditors generally; or (g) there is a government expropriation of any material portion of the assets of the other party hereto. 

SECTION 4.5 Effect of Termination. 

(a) In any event, no termination, cancelation or expiration of this Agreement shall prejudice the right of either party hereto to recover any
payment due at the time of termination, cancelation or expiration (or any payment accruing as a result thereof), nor shall it prejudice any cause of action or claim of either party hereto accrued or to accrue by reason of any breach or default by
the other party hereto. 
 (b) Survival. Notwithstanding anything to the contrary contained herein, this
Section 4.5(b), Section 5.2, Article III, Article VI and Article VII of this Agreement shall survive the termination of this Agreement.

 ARTICLE V 

INTELLECTUAL PROPERTY, COOPERATION AND CONFIDENTIALITY 

SECTION 5.1 Cooperation; Access. 

(a) NiSource Services shall, and shall cause each of the NiSource Parties to, permit Columbia Services and its employees and representatives
access, on Business Days during hours that constitute regular business hours for NiSource Services and upon reasonable prior request, to the premises of the NiSource Parties and such data, books, records and personnel designated by NiSource Services
and the NiSource Parties as involved in receiving or overseeing the Services as Columbia Services may reasonably request for the purposes of providing the Services. Columbia Services shall provide NiSource Services, upon reasonable prior written
notice, such documentation relating to the provision of the Services as NiSource Services may reasonably request for the purposes of confirming any Invoiced Amount or other amount payable pursuant to any Commingled Invoice Statement or otherwise
pursuant to this Agreement. Any documentation so provided to Columbia Services pursuant to this Section 5.1(a) shall be subject to the confidentiality obligations set forth in Section 5.2. 

(b) Columbia Services shall provide the NiSource Parties with such advice, assistance and information in connection with the performance of
the Services as NiSource Services may from time to time reasonably require. NiSource Services and Columbia Services shall also liaise as appropriate to ensure that the Services are carried out in accordance with the provisions of Schedule A
hereto, and where reasonably practicable Columbia Services shall comply with any instructions that NiSource Services shall reasonably issue from time to time concerning the manner in which the Services shall be provided to the NiSource Parties. 

(c) Columbia Services and NiSource Services shall each use reasonable best efforts to keep each other informed of any special requirements
applicable to the carrying out of the Services. To the extent reasonably necessary and appropriate Columbia Services shall promptly take steps where reasonably practicable to comply with such special requirements. In the event that these steps shall
result in any increase or reduction in the actual cost to Columbia Services of providing the relevant Services then the fees payable pursuant to Section 3.1 shall be increased or reduced accordingly. 

SECTION 5.2 Confidentiality. Each party hereto agrees that it shall treat in confidence all documents, materials and other
information that it shall have obtained regarding the other party during the course of the performance of this Agreement and the transactions contemplated by this Agreement that the receiving party should reasonably recognize as being of a
confidential nature (“Confidential Information”). Except in the course of providing the Services pursuant hereto, Confidential Information shall not be communicated to any third party (other than to the parties’ respective
counsel, accountants, financial advisors, consultants or lenders or employees who need to know such Confidential Information). No Person shall use any Confidential Information in any manner whatsoever except solely for the purpose of carrying out
the 

  
 9 








 
transactions contemplated by this Agreement or as otherwise contemplated by this Agreement. The obligation of each party to treat Confidential Information in confidence shall not apply to any
information that (a) is on the date hereof in such party’s possession; provided that such information is not known to such party to be subject to another confidentiality agreement with, or other obligation of secrecy to, the other
party or any third party and such information may be disclosed pursuant to the Separation and Distribution Agreement; (b) is on the date hereof or hereafter becomes available to the public other than as a result of a disclosure, directly or
indirectly, by such party or its agents; (c) is on the date hereof or hereafter becomes available to such party on a non-confidential basis from a source other than the other party or any of the other party’s agents; provided that
(i) such source is not known by the receiving party to be subject to a confidentiality agreement with, or other obligation of secrecy to, the disclosing party or any third party and (ii) such information may be disclosed pursuant to the
Separation and Distribution Agreement or (d) can be shown by such party to have been independently developed by such party and such information may be disclosed pursuant to the Separation and Distribution Agreement. The foregoing
confidentiality and nondisclosure obligations shall not apply to the extent any such Confidential Information is required to be disclosed by applicable law; provided that, in such event, the party required to disclose such information
provides the other party with prompt advance notice of such required disclosure so that such other party shall have the opportunity, if it so desires, to seek a protective order or other appropriate remedy. 

SECTION 5.3 Intellectual Property. NiSource Services grants to the Columbia Parties a limited, non-exclusive, fully paid-up,
nontransferable, revocable license, without the right to sublicense, for the term of this Agreement to use all intellectual property owned by or, to the extent permitted by the applicable license, licensed to NiSource Services solely to the extent
necessary for the Columbia Parties to perform the Services. 
 SECTION 5.4 Privileged Matters.  

(a) Each of NiSource Services and Columbia Services agrees to maintain, preserve and assert all privileges, including privileges arising under
or relating to the attorney-client relationship (which shall include the attorney-client and work product privileges), not heretofore waived, that relate to the Columbia Business or the NiSource Business during the Service Period (each a
“Privilege”). Each party hereto acknowledges and agrees that any costs associated with asserting any Privilege shall be borne by the party requesting that such Privilege be asserted. Each party hereto agrees that neither it nor any
of its Affiliates shall waive any Privilege that could be asserted by the other party hereto or any of its Affiliates under applicable Law without the prior written consent of the other party (which consent shall not be unreasonably withheld,
conditioned or delayed). The rights and obligations created by this Section 5.4 shall apply to all information relating to the NiSource Business or the Columbia Business as to which, but for the performance of this Agreement and the
transactions contemplated by this Agreement, any party would have been entitled to assert or did assert the protection of a Privilege (“Privileged Information”), including (i) any and all information generated prior to the
Distribution Date but which, after the Distribution Date is in the possession of any party and (ii) all information generated, received or arising after the Distribution Date. 

(b) Upon receipt by either party of any subpoena, discovery or other request that may call for the production or disclosure of Privileged
Information or if any party obtains knowledge 

  
 10 








 
that any current or former director, officer or employee of NiSource Services, Columbia Services or any of their respective Affiliates has received any subpoena, discovery or other request that
may call for the production or disclosure of Privileged Information of the other party or any of such other party’s Affiliates, such party shall notify promptly the other party hereto of the existence of the request and shall provide the other
party hereto a reasonable opportunity to review the information and to assert any rights it or any of its Affiliates may have under this Section 5.4 or otherwise to prevent the production or disclosure of Privileged Information. Each
party hereto agrees that it will not produce or disclose, or permit any of its Affiliates to produce or disclose, any information that may be covered by a Privilege of the other party hereto or any of such other party’s Affiliates under this
Section 5.4 unless (i) the other party has provided its written consent to such production or disclosure (which consent shall not be unreasonably withheld, conditioned or delayed) or (ii) a court of competent jurisdiction has
entered a final, nonappealable order finding that the information is not entitled to protection under any applicable Privilege. 
 (c) The
access to and transfer of all Privileged Information pursuant to this Agreement is made in reliance on the agreement of NiSource Services and Columbia Services set forth in Section 5.2 and this Section 5.4 to maintain the
confidentiality of Privileged Information and to assert and maintain all applicable privileges. The parties agree that their respective rights to any access to or transfer of Privileged Information, access to Persons, the furnishing of notices and
documents and other cooperative efforts between the Parties contemplated by this Agreement, shall not be deemed a waiver of any Privilege that has been or may be asserted under this Agreement or otherwise. Nothing in this Agreement shall operate to
reduce, minimize or condition the rights granted under, or the obligations imposed by, this Section 5.4. 
 (d) If any dispute
arises between NiSource Services and any Columbia Services regarding whether a Privilege should be waived to protect or advance the interests of either NiSource Services or Columbia Services, each party hereto agrees that it shall (i) negotiate
with the other party hereto in good faith, (ii) endeavor to minimize any prejudice to the rights of the other party hereto and (iii) not unreasonably withhold, condition or delay consent to any request for waiver by the other party hereto.
Nevertheless, each party is permitted to withhold its consent to the waiver of a privilege for the purpose of protecting its own legitimate interests. 

ARTICLE VI 
 LIMITATION
OF LIABILITY, INDEMNIFICATION AND REMEDIES 
 SECTION 6.1 Indemnity. 

(a) The liability of the Columbia Parties and their Affiliates and all their respective officers, employees, directors, agents and other
representatives (collectively, the “Columbia Indemnified Parties”) with respect to this Agreement or in connection with the performance, delivery or provision of any service provided under this Agreement, whether in contract, tort
(including negligence or strict liability) or otherwise, shall be limited to the liability of the Columbia Parties for any Losses of the applicable NiSource Party and its Affiliates and their respective officers, employees, directors, agents and
other representatives (collectively, the “NiSource Indemnified Parties”) arising from Columbia Services’ willful misconduct or gross negligence in providing the Services pursuant hereto; provided that in no event shall
such 

  
 11 








 
liability exceed the fees previously paid to Columbia Services by NiSource Services in respect of the service from which such liability flows, or to the extent the liability arises out of
Columbia Services’ breaching this Agreement by not providing the Services (or level of services) required hereunder, then the liability shall not exceed the higher of the fees previously paid to Columbia Services by NiSource Services in respect
of the service from which such liability flows or the amount that Columbia Services would have been paid by NiSource Services for such services for the agreed-upon term of such services (not to exceed 24 months from the date hereof). 

(b) NiSource Services will, and will cause the other NiSource Parties to, indemnify the Columbia Indemnified Parties from any and all Losses

of profits or revenue, loss of business, interruption of business or otherwise) with respect to its performance or nonperformance hereunder, or the provision of or failure to provide any service hereunder, whether such damages or other relief are
sought based on breach of contract, negligence, strict liability or any other legal or equitable relief.

 SECTION 7.2 Assignment. No party to this Agreement may assign any of its rights or
delegate any of its obligations under this Agreement without the written consent of the other party hereto, which consent may be withheld in such other party’s sole and absolute discretion and any assignment or attempted assignment in violation
of the foregoing will be null and void; provided, however, that Columbia Services may delegate its duties hereunder to such Affiliates or third-party service providers as may be qualified to provide the Services and provided,
further that Columbia Services will reasonably assist in the process of transitioning such service to NiSource Services or NiSource’s designee prior to, and in lieu of, any such delegation.

SECTION 7.5 Force Majeure. Neither party hereto shall be in default of this Agreement by reason of its delay in the performance
of, or failure to perform, any of its obligations hereunder (other than the payment of money) if such delay or failure is caused by acts of God, acts of civil or military authority, embargoes, acts of terrorism, epidemics, war, riots, insurrections,
fires, explosions, earthquakes, floods, unusually severe weather conditions, labor problems or unavailability of parts, or, in the case of computer systems, any failure in electrical or air conditioning equipment or other events that arise from
circumstances beyond the reasonable control of such party. In the event of any such excused delay, the time for performance shall be extended for a period equal to the time lost by reason of the delay.
