PERFORMANCE OF SERVICES 
 3.1 General. (a) During the Term, and subject to the terms and conditions of this Agreement, CRL will use commercially reasonable efforts to provide, or cause to be provided, on behalf
of the GP and for the benefit of MTS and the MTS Affiliated Entities, the Services to MTS and the MTS Affiliated Entities. Unless specifically provided to the contrary on Annex B, all Services provided pursuant to this Agreement shall be
performed or provided, as applicable: (i) with the use of reasonable care; (ii) consistent with this Agreement and in substantially the same manner (including as to level, quality and timeliness) as such Services have been provided by
MTS’s former employees prior to the Effective Date; (iii) in material compliance with applicable laws, rules and regulations; and (iv) with substantially the same priority under comparable circumstances as it provides such services to
itself and its Affiliates. All Services performed or provided by CRL shall be under the direction, supervision and control of the GP. 
 (b) Notwithstanding anything to the contrary in this Agreement, neither CRL, nor any of its Affiliates, shall be required to perform Services or take any actions relating thereto that conflict with or
violate any applicable law, contract, license, sublicense, authorization, certification or permit. 

  
 5 

 (c) CRL will provide such suitably qualified and experienced personnel to GP for the
performance of Services as CRL is able to make available to GP, and GP will have the right to approve such personnel. In the event that CRL is unable to provide suitably qualified and experienced personnel, as determined in good faith by GP, GP may
engage (or hire a third party to engage) personnel to provide the relevant Services. 
 3.2 Additional Services.
If GP or MTS reasonably determines that additional services (not listed on Annex B) of the type that are customarily required by similarly situated companies in the midstream petroleum industry are necessary to conduct the business of MTS,
then GP or MTS may provide written notice thereof to CRL in accordance with Section 3.3. Upon receipt of such notice by CRL, if CRL is willing, in its sole discretion, to provide such additional service during the Term, the Parties will
negotiate in good faith an amendment to Annex B to include the additional service (each such service an “Additional Service”), the terms and conditions for the provision of each Additional Service and the Fees payable to CRL
for each Additional Service, such Fees to be determined with the intent that they reflect an arm’s-length standard. 

3.3 Modification; Third Party Providers. (a) Any requests or other communications from a Party to another Party
regarding (i) the Services, (ii) any modification or alteration to the provision of the Services or (iii) the provision of Additional Services must be made by an Authorized Representative (it being understood that the receiving Party
shall not be obligated to agree to any modification or alteration requested thereby). 
 (b) Each Party acknowledges and agrees
that certain of the Services to be provided under this Agreement have been, and will continue to be provided to GP or MTS by Third Parties designated by CRL. To the extent so provided, CRL shall use commercially reasonable efforts to (i) cause
such Third Parties to provide such Services under this Agreement and (ii) enable GP, MTS and the MTS Affiliated Entities to avail themselves of such Services; provided, however, that if any such Third Party is unable or unwilling
to provide any such Services, the Parties agree to use their commercially reasonable efforts to determine the manner in which such Services can best be provided. It is acknowledged and agreed that any costs or expenses to be incurred in connection
with obtaining Services from a Third Party shall be paid by GP or MTS; provided that CRL shall use commercially reasonable efforts to communicate in advance the expected costs or expenses to be incurred. 

3.4 Disclaimer of Warranties; Force Majeure. 
 (a) Except as expressly set forth in this Agreement, to the fullest extent permitted by applicable law: (i) GP and MTS acknowledge and agree that CRL makes no warranties of any kind with respect to
the Services; and (ii) CRL expressly disclaims all warranties, expressed or implied, of any kind with respect to the Services, including any warranty of non-infringement, merchantability, fitness for a particular purpose or conformity to any
representation or description as to the Services provided hereunder. EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE SERVICES WILL BE PROVIDED AS IS, WHERE IS, WITH ALL FAULTS, AND WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING ANY
WARRANTY OF NON-INFRINGEMENT, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, CONFORMITY TO ANY REPRESENTATION OR DESCRIPTION, TITLE OR ANY OTHER WARRANTY WHATSOEVER. 

  
 6 

 (b) If any Party is prevented from or delayed in complying, either totally or in part, with
any of the terms or provisions of this Agreement, excluding any obligation to make payments hereunder, by reason of fire, flood, storm, strike, walkout, lockout or other labor trouble or shortage, delays by unaffiliated suppliers or carriers,
shortages of fuel, power, raw materials or components, equipment failure, any law, order, proclamation, regulation, ordinance, demand, seizure or requirement of any governmental authority, riot, civil commotion, war, rebellion, act of terrorism,
nuclear or other accident, explosion, casualty, pandemic, or act of God, or act, omission or delay in acting by any governmental or military authority or Third Party or any other cause, whether or not of a class or kind listed in this sentence,
beyond the reasonable control and without the fault of the affected Party (each a “Force Majeure Event”), then upon notice to the other Parties, the affected provisions and/or other requirements of this Agreement shall be suspended
during the period of such Force Majeure Event and, unless otherwise set forth herein to the contrary, the Party affected by the Force Majeure Event shall have no liability to the other Parties or any of their Affiliates or any other Person in
connection therewith. Upon becoming aware of a Force Majeure Event, the Party affected by the Force Majeure Event shall promptly notify the other Parties in writing of the existence and anticipated duration of such Force Majeure Event. Each Party
shall use commercially reasonable efforts to promptly mitigate or overcome such Force Majeure Event as soon as possible; provided, however, that nothing in this Section 3.4(b) will be construed to require the settlement of
any strike, walkout, lockout or other labor dispute on terms which, in the reasonable judgment of the affected Party, are contrary to its interest. It is understood that the settlement of a strike, walkout, lockout or other labor dispute will be
entirely within the discretion of the affected Party. If CRL is unable to provide any of the Services due to a Force Majeure Event, each Party shall use commercially reasonable efforts to cooperatively seek a solution that is mutually satisfactory
to the Parties. GP and MTS shall have the right, but not the obligation, to engage subcontractors to perform any such Services that CRL is unable to provide for the duration of the Force Majeure Event; provided however, that any Fees
paid or payable by MTS to CRL under this Agreement shall be reduced (or refunded, if applicable) on a dollar-for-dollar basis by any amounts paid by or on behalf of MTS to any subcontractors with respect to any Services that CRL is unable to perform
as a result of a Force Majeure Event. For the avoidance of doubt, if GP or MTS engages subcontractors to perform any Services during a Force Majeure Event, CRL shall not be required to refund, or otherwise be liable for, any amounts in excess of the
aggregate Fees paid or owed to CRL with respect to such Services during the period of the Force Majeure Event. 
 ARTICLE IV

 COOPERATION 
 4.1 Cooperation. Each Party shall use good faith efforts to cooperate with the other Parties in all matters relating to the provision and receipt of the Services, including providing
in a timely manner any information, documentation, approvals and acceptances reasonably requested by the Parties, other than information and documentation protected by attorney-client privilege. 

  
 7 

 4.2 Consents. (a) Each Party shall provide reasonable cooperation to
obtain all Third Party consents for any Third Party software or other Third Party intellectual property related to the provision of the Services sufficient to enable CRL to perform the Services in accordance with this Agreement; provided,
however, that no Party shall be obligated under this Agreement to pay any consideration (other than de minimis transfer fees), grant any concession or incur any liability to any Third Party to obtain any such Third Party’s consent.

 (b) If any Third Party consent or approval required for the provision of Services hereunder is not obtained, then, unless and
until such Third Party consent or approval is obtained, the Parties shall, to the extent practicable, cooperate with each other in achieving a reasonable alternative arrangement for GP and MTS to obtain such Services. 

ARTICLE V 

FEES 

5.1 Fees. GP and MTS shall pay CRL the Fees for the Services as set forth on Annex B and in accordance with
Article VI. 
 5.2 Taxes. To the extent required by applicable law, CRL shall add to any Fees due under
this Agreement amounts equal to any sales, use or similar taxes, however designated or levied, based upon the provision of the Services. CRL shall be solely responsible for the collection and remittance of any such taxes to the appropriate tax
authorities. The Parties shall cooperate with each other to minimize any such taxes to the extent reasonably practicable. If additional taxes are determined to be due with respect to the Services provided hereunder as a result of an audit by any
applicable tax authority, MTS agrees to reimburse CRL for the additional taxes due from CRL including interest and penalty. MTS shall have the right to contest with the tax authority at MTS’s sole expense the amount of any taxes or the result
of any audit. CRL will be responsible for any penalty or interest resulting from its failure to remit any invoiced taxes. Notwithstanding anything in this Agreement to the contrary, this Section 5.2 shall, to the fullest extent permitted
by applicable law, survive the termination of this Agreement and remain in effect until the expiration of the relevant statutes of limitations. 
 5.3 Adjustments. In the event of the termination of this Agreement prior to the scheduled expiration of the Term (a) with respect to any Services for which the Fee for such Services is
charged as a flat monthly rate, if termination occurs other than the end of the month, the Fee for that month shall be prorated to reflect a partial month, and (b) with respect to any other Services, all amounts due pursuant to the terms hereof
with respect to the Services shall be appropriately prorated and reduced to reflect such shortened period during which such Services are actually provided, and CRL shall refund to GP or MTS the appropriate prorated amount for any such Services that
have been paid for in advance. Notwithstanding the immediately preceding sentence, to the extent any amounts due or advances made hereunder related to costs or expenses that have been or will be incurred and that cannot be recovered by CRL such
amounts due or advances made shall not be prorated or reduced and CRL shall not be required to refund any prorated amount for such costs or expenses; and GP or MTS shall reimburse CRL for any Third Party cancellation or similar charges incurred as a
result of such early termination. 

  
 8 

 ARTICLE VI 
 INVOICE AND PAYMENT; AUDIT 
 6.1 Invoices and Payment. Within
20 days following the end of each month during the Term, CRL will submit to MTS for payment a written statement of amounts due under this Agreement for such month. The statement will set forth the Fees, in the aggregate and itemized, based on the
descriptions set forth on Annex B. Each statement will contain reasonably satisfactory documentation in support of such amounts as specified therein and such other supporting detail as the other Party may reasonably require to validate such
amounts due. Except as otherwise provided in this Agreement, GP and MTS shall reimburse CRL in accordance with this Article VI for all out-of-pocket costs and expenses actually paid by CRL to Third Parties on behalf of MTS in connection with
providing the Services (“Expenses”). 
 6.2 Timing of Payment; No Offsets. MTS will pay all
amounts due pursuant to this Agreement within 10 days after the receipt of the invoice therefor. MTS shall not offset any amounts owing to it by CRL or any of its Affiliates against amounts payable hereunder. 

6.3 Non-Payment. If MTS fails to pay the full amount of any invoice within 30 days after its receipt of the invoice,
such failure shall be considered a material default under this Agreement for purposes of Section 10.2. Payments made after the date they are due shall bear interest at the Default Rate. 

6.4 Payment Disputes. Subject to Section 6.5, MTS may object to any amounts for any Service invoiced to it at
any time before or after payment is made, provided such objection is made in writing to CRL within 90 days following the end of the calendar year in which such Services were performed. MTS shall timely pay the disputed items in full while resolution
of the dispute is pending; provided, however, that CRL shall pay interest at the Default Rate on any amounts it is required to return to GP or MTS upon resolution of the dispute. Payment of any amount shall not constitute approval
thereof. Any dispute under this Section 6.4 shall be resolved in accordance with the provisions of Section 12.2. 
 6.5 Audit Rights. (a) MTS may, at its own cost and expense, audit (or cause an independent Third Party auditor to audit) the books and records of CRL to the extent necessary to
determine CRL’s compliance with this Agreement with respect to Fees and Expenses charged or the performance of CRL’s obligations under this Agreement. MTS shall have the right to conduct such audit no more than once with respect to each
calendar year during the Term; provided, however, that any such audit shall not be commenced later than 12 months after the end of the calendar year to be audited. 

(b) Any audit shall be conducted during regular business hours and in a manner that does not unreasonably interfere with the operations
of CRL. MTS shall provide notice to CRL not less than 30 days prior to the commencement of the audit and shall specify the date on which the audit will commence. If the audit concludes that an overpayment or underpayment has occurred during the
audited period, then MTS may raise an objection pursuant to Section 6.4.

 ARTICLE VII 
 CONTROL OF SERVICES; OWNERSHIP OF ASSETS 
 7.1 Control of
Services. Notwithstanding anything to the contrary in this Agreement, GP, for itself and for MTS and the MTS Affiliated Entities, shall at all times have exclusive authority to manage and control the business and operations of CRL. In
connection with managing and controlling the business and operations of CRL, the provision of the Services shall be under the ultimate direction, control and supervision of GP. 

7.2 Employee Status. During the Term of this Agreement: 

(a) No employee of CRL shall be deemed an employee of GP or MTS by reason of such employee’s involvement in providing Services
provided hereunder. CRL shall bear the sole responsibility for payment of each such employee’s wages, benefits, all withholding obligations to federal, state and local taxation and insurance authorities and all other costs and expenses
associated with such employees, including workers’ compensation expense. 
 (b) Subject to the rights of GP to direct and
control the performance and provision of the Services as set forth in this Agreement, CRL shall serve as the employer directly controlling the personnel that it provides to perform such Services and shall retain the exclusive right to review
employees’ performance, determine employees’ compensation and benefits, discipline employees and determine whether or not to continue employees’ employment. 
 (c) Notwithstanding anything in this Agreement to the contrary, no provision of this Agreement (i) shall be construed as granting employees any employment rights for a specific duration or
constraining CRL’s right to terminate the employment relationship with any of its employees, or (ii) affecting the ability of any CRL employee to be considered for transfers or promotions to positions listed on any internal job posting
system. 
 7.3 Assets. All procedures, methods, systems, strategies, tools, equipment, facilities and other
resources used by a Party or any of its Affiliates in connection with the provision of the Services hereunder shall remain the property of such Party or its Affiliates and, except as otherwise provided herein, shall at all times be under the sole
direction and control of such Person. No license under any patents, know-how, trade secrets, copyrights or other rights is granted by this Agreement or any disclosure in connection with this Agreement by any Party. 

ARTICLE VIII 
 CONFIDENTIALITY; SECURITY 
 8.1 Confidentiality. 

(a) From and after the Effective Date, each Party shall hold, and shall cause its respective Subsidiaries and Affiliates and its and their
directors, managers, officers, employees, agents, consultants, advisors, and other representatives (collectively, “Representatives”) to hold all Confidential Information of another Party in strict confidence, with at least the same
degree of 

  
 10 

 
care that applies to such Party’s confidential and proprietary information and shall not use such Confidential Information except in connection with the performance of the Services
hereunder, and shall not release or disclose such Confidential Information to any other Person, except its Representatives. Each Party shall be responsible for any breach of this section by any of its Representatives. 

(b) If a Party receives a subpoena or other demand for disclosure of Confidential Information received from any other Party or must
disclose to a governmental authority any Confidential Information received from such other Party in order to obtain or maintain any required governmental approval, the receiving Party shall, to the extent legally permissible, provide notice to the
providing Party before disclosing such Confidential Information. Upon receipt of such notice, the providing Party shall promptly either seek an appropriate protective order, waive the receiving Party’s confidentiality obligations hereunder to
the extent necessary to permit the receiving Party to respond to the demand, or otherwise fully satisfy the subpoena or demand or the requirements of the applicable governmental authority. If the receiving Party is nonetheless legally compelled to
disclose such Confidential Information, or if the providing Party does not promptly respond as contemplated by this section, the receiving Party may disclose that portion of Confidential Information required to be disclosed by the subpoena or other
demand. 
 (c) Each Party acknowledges that the disclosing Party would not have an adequate remedy at law for the breach by the
receiving Party of any one or more of the covenants contained in this Section 8.1 and agrees that, in the event of such breach, the disclosing Party may, in addition to the other remedies that may be available to it, to the fullest
extent permitted by applicable law, apply to a court for an injunction to prevent breaches of this Section 8.1 and to enforce specifically the terms and provisions of this Section 8.1. Notwithstanding any other section
hereof, the provisions of this Section 8.1 shall survive the termination of this Agreement. 
 8.2 System
Security. 
 (a) If any Party is given access to another Party’s computer systems or software (collectively,
“Systems”) in connection with the Services, the Party given access (the “Availed Party”) shall comply with all of the other Party’s system security policies, procedures and requirements that have been provided
to the Availed Party in advance and in writing (collectively, “Security Regulations”), and shall not tamper with, compromise or circumvent any security or audit measures employed by such other Party. The Availed Party shall access
and use only those Systems of the other Party for which it has been granted the right to access and use. 
 (b) Each Party shall
use commercially reasonable efforts to ensure that only those of its personnel who are specifically authorized to have access to the Systems of the other Party gain such access, and each Party shall use commercially reasonable efforts to prevent
unauthorized access, use, destruction, alteration or loss of information contained in the Systems, including notifying its respective personnel of the restrictions set forth in this Agreement and of the Security Regulations. 

  
 11 

 (c) If, at any time, the Availed Party determines that any of its personnel has sought to
circumvent, or has circumvented, the Security Regulations, that any unauthorized Availed Party personnel have accessed the Systems, or that any of its personnel has engaged in activities that may lead to the unauthorized access, use, destruction,
alteration or loss of data, information or software of the other Party, the Availed Party shall promptly terminate any such person’s access to the Systems and promptly notify the other Party. In addition, such other Party shall have the right
to deny personnel of the Availed Party access to its Systems upon notice to the Availed Party in the event that the other Party reasonably believes that such personnel have engaged in any of the activities described in this
Section 8.2(c) or otherwise pose a security concern. The Availed Party shall use commercially reasonable efforts to cooperate with the other Party in investigating any apparent unauthorized access to such other Party’s Systems.

 ARTICLE IX 
 NO PARTNERSHIP OR AGENCY RELATIONSHIP 
 9.1 No Partnership or Agency
Relationship; Independent Contractor. Nothing in this Agreement is intended or shall be deemed to constitute a partnership, agency, franchise or joint venture relationship among the Parties or any of their Affiliates. Neither Party shall
have power to control the activities and operations of the other Party or its Affiliates, nor to bind or commit the other Party or its Affiliates. CRL shall at all time be acting as an independent contractor under this Agreement.

Procedures. 
 (a) The Indemnified Party agrees that within a reasonable period of time after it becomes aware of facts

Party. 
 (b) The Indemnifying Party shall have the right to control all aspects of the defense of (and any counterclaims with
respect to) any claims brought against the Indemnified Party that are covered by the indemnification under this Article XI, including, without limitation, the selection of counsel, determination of whether to appeal any decision of any court
and the settling of any such claim or any matter or any issues relating thereto; provided, however, that no such settlement for only the payment of money shall be entered into without the consent of the Indemnified Party unless
it includes a full release of the Indemnified Party from such claim; and provided further, that no such settlement containing any form of injunctive or similar relief shall be entered into without the prior written consent of the
Indemnified Party, which consent shall not be unreasonably delayed or withheld. 
 (c) The Indemnified Party agrees to cooperate
in good faith and in a commercially reasonable manner with the Indemnifying Party, with respect to all aspects of the defense of and pursuit of any counterclaims with respect to any claims covered by the indemnification under this Article XI,
including, without limitation, the prompt furnishing to the Indemnifying Party of any correspondence or other notice relating thereto that the Indemnified Party may receive, permitting the name of the Indemnified Party to be utilized in connection

and (ii) all amounts recovered by the Indemnified Party under contractual indemnities from Third Parties. 
 (e)
Notwithstanding anything to the contrary hereunder, no cause of action, dispute or claim for indemnification may be asserted against any Party or submitted to arbitration or legal proceedings which accrued more than two years after the later of
(i) the occurrence of the act or event giving rise to the underlying cause of action, dispute or claim and (ii) the date on which such act or event was, or should have been, in the exercise of reasonable due diligence, discovered by the
Party asserting the cause of action, dispute or claim.

MISCELLANEOUS

 12.2 Choice of Law; Mediation; Submission to Jurisdiction. 
 (a) This
Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to principles of conflict of laws. The Parties hereby declare that it is their intention that this Agreement shall be regarded as made
under the laws of the State of Delaware and that the laws of said State shall be applied in interpreting its provisions in all cases where legal interpretation shall be required. Each of the Parties agrees (a) that this Agreement involves at
least $100,000.00, and (b) that this Agreement has been entered into by the Parties in express reliance upon 6 Del. C. § 2708. Each of the Parties hereby irrevocably and unconditionally agrees (i) to be subject to the exclusive
jurisdiction of the courts of the State of Delaware and of the federal courts sitting in the State of Delaware, and (ii) (A) to the extent such Party is not otherwise subject to service of process in the State of Delaware, to appoint and
maintain an agent in the State of Delaware as such Party’s agent for acceptance of legal process, and (B) that, to the fullest extent permitted by applicable law, service of process may also be

  
 15 

 
made on such Party by prepaid certified mail with a proof of mailing receipt validated by the United States Postal Service constituting evidence of valid service, and that service made pursuant
to (b) (A) or (B) above shall, to the fullest extent permitted by applicable law, have the same legal force and effect as if served upon such Party personally within the State of Delaware. The foregoing consents to jurisdiction and
service of process shall not constitute general consents to service of process in the State of Delaware for any purpose except as provided herein and shall not be deemed to confer rights on any person other than the Parties. 

(b) If the Parties cannot resolve any dispute or claim arising under this Agreement, then no earlier than 10 days nor more than 60 days
following written notice to the other Parties, any Party may initiate mandatory, non-binding mediation hereunder by giving a notice of mediation (a “Mediation Notice”) to the other Parties. In connection with any mediation pursuant

Amendment. This Agreement may only be amended, modified or supplemented by a written instrument signed by an Authorized Representative of each of CRL, GP and MTS. 
 12.4 Waiver. Any term or provision of this Agreement may be waived, or the time for its performance may be extended, by the Party or Parties entitled to the benefit thereof. Any such waiver
shall be validly and sufficiently given for the purposes of this Agreement if, as to any Party, it is in writing signed by an authorized representative of such Party. The failure of any Party to enforce at any time any provision of this Agreement
shall not be construed to be a waiver of such provision, or in any way to affect the validity of this Agreement or any part hereof or the right of any Party thereafter to enforce each and every such provision. No waiver of any breach of this
Agreement shall be held to constitute a waiver of any other or subsequent breach. 
 12.5 Partial Invalidity.
Wherever possible, each provision hereof shall be interpreted in such a manner as to be effective and valid under applicable law, but in case any one or more of the provisions contained herein shall, for any reason, be held to be invalid,
illegal or unenforceable in any respect, such provision or provisions shall be ineffective to the extent, but only to the extent, of such invalidity, illegality or unenforceability without invalidating the remainder of such provision or provisions

This Agreement shall be binding upon and inure to the benefit of the Parties and their successors and permitted assigns; provided, however, that the rights and obligations of any Party under this Agreement shall not be assignable
by such Party

assignee (whether by merger, liquidation (including successive mergers or liquidations) or otherwise).

services hereunder to be performed with the same degree of diligence and care that it would exercise if managing its own property, and in accordance with all applicable laws, rules and regulations of the appropriate governmental authorities.
Notwithstanding anything herein to the contrary, MPL has no duty to advance funds on behalf of MLH in the performance of its duties under this Agreement, but MPL shall notify MLH if any insufficiency of funds exists.

 4 

 
WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING ANY WARRANTY OF NON-INFRINGEMENT, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, CONFORMITY TO ANY REPRESENTATION OR DESCRIPTION,
TITLE OR ANY OTHER WARRANTY WHATSOEVER. 
 3.3 Force Majeure. If any Party is prevented from or delayed in complying,
either totally or in part, with any of the terms or provisions of this Agreement, excluding any obligation to make payments hereunder, by reason of fire, flood, storm, strike, walkout, lockout or other labor trouble or shortage, delays by
unaffiliated suppliers or carriers, shortages of fuel, power, raw materials or components, equipment failure, any law, order, proclamation, regulation, ordinance, demand, seizure or requirement of any governmental authority, riot, civil commotion,
war, rebellion, act of terrorism, nuclear or other accident, explosion, casualty, pandemic, or act of God, or act, omission or delay in acting by any governmental or military authority or Third Party or any other cause, whether or not of a class or
kind listed in this sentence, beyond the reasonable control and without the fault of the otherwise defaulting Party (each, a “Force Majeure Event”), then upon notice to the other Parties, the affected provisions and/or other
requirements of this Agreement shall be suspended during the period of such Force Majeure Event and, unless otherwise set forth herein to the contrary, the Party affected by the Force Majeure Event shall have no liability to the other Parties, its
Affiliates or any other Person in connection therewith. Upon becoming aware of a Force Majeure Event, the Party affected by the Force Majeure Event shall promptly notify the other Parties in writing of the existence of such Force Majeure Event and
the anticipated duration of the Force Majeure Event. Each Party shall use commercially reasonable efforts to mitigate or overcome the effects of such Force Majeure Event as soon as possible; provided, however, that nothing in this
Section 3.3 will be construed to require the settlement of any strike, walkout, lockout or other labor dispute on terms which, in the reasonable judgment of the affected Party, are contrary to its interest. It is understood that the settlement
of a strike, walkout, lockout or other labor dispute will be entirely within the discretion of the affected Party. If MPL is unable to provide any of the Management Services due to a Force Majeure Event, each Party shall use commercially reasonable
efforts to cooperatively seek a solution that is mutually satisfactory to the Parties. MLH shall have the right, but not the obligation, to engage subcontractors to perform such obligations for the duration of the Force Majeure Event, it being
agreed that any fees paid or payable by MLH under this Agreement with respect to the Management Service affected by such Force Majeure Event shall be reduced (or refunded, if applicable) on a dollar-for-dollar basis for all amounts paid by MLH to
such subcontractors; provided, however, that MPL shall not be responsible for the amount of fees paid by MLH to any such subcontractors to perform such Management Services to the extent such fees exceed the Management Fees for the
applicable period of the Force Majeure Event. 
 3.4 No Partnership. Nothing in this Agreement will be deemed to create a
partnership, joint venture or similar relationship between MLH and MPL, and neither MPL nor any of its Affiliates has any power to bind MLH. MPL shall act as an independent contractor in the performance of its duties hereunder.

 ARTICLE 4 
 EMPLOYMENT OF PERSONNEL; MANAGEMENT FEE 
 4.1 Personnel. MPL shall
obtain, whether as employees or independent contractors, such personnel as may be required to perform the Management Services. All such personnel, whether full or part-time, shall at all times remain employees or independent contractors of MPL, an
MPL Affiliated Entity or a Third Party and shall not become or be deemed to be employees of MLH or any MLH Affiliated Entity. 

4.2 Management Fee. MPL shall be paid a management fee (the “Management Fee”) of $17,000 per month starting as of
the Effective Date and payable by the first day of each month. The Management Fee for the month of the Effective Date will be pro-rated based on the number of days remaining in such month. MLH shall reimburse MPL for any expenditures made by MPL on
behalf of MLH under Section 5.2 or otherwise with the consent of MLH within 30 days of receipt by MLH of an invoice for such reimbursement. 
 4.3 Adjustment of Management Fee. The Management Fee shall be fixed until December 31, 2013. Thereafter, the Management Fee shall be adjusted annually, on the first day of the month following
each anniversary of the Effective Date, by the same percentage that the annual “Average Hourly Earnings of Production Workers” reported in the North American Industry Classification System, Section 486, as published by the U.S.
Department of Labor, Bureau of Labor Statistics, changed during the preceding calendar year; provided, however, that in no event shall the Management Fee ever be adjusted to less than the amount of the Management Fee in effect as of
the Effective Date due to a change in such index. Should any significant change in the scope of the work to be conducted by MPL become necessary during the Term of this Agreement, the Party first becoming aware of such necessity shall promptly
notify the other Party, at which time the Parties will enter into good faith negotiations to examine such necessary change in the scope of such work and adjust the Management Fee accordingly. In the event that, after such good faith negotiations,
the Parties are unable to agree on an appropriate adjustment to the Management Fee, either Party may terminate this Agreement without liability to the other Party. 
 4.4 Taxes. To the extent required by applicable law, MPL shall add to any Management Fees due under this Agreement amounts equal to any applicable sales, use or similar taxes, however designated or
levied, based upon the provision of the Management Services. MPL shall be solely responsible for the collection and remittance of any such taxes to the appropriate tax authorities. The Parties shall cooperate with each other to minimize any such
taxes to the extent reasonably practicable. If additional taxes are determined to be due with respect to the Management Services provided hereunder as a result of an audit by any applicable tax authority, MLH agrees to reimburse MPL for the
additional taxes due from MPL, including interest and penalties. MLH shall have the right to contest with the applicable tax authority, at MLH’s sole expense, the amount of any taxes or the result of any audit. MPL will be responsible for any
penalty or interest resulting from its failure to remit any invoiced taxes. Notwithstanding anything in this Agreement to the contrary, this Section 4.4 shall, to the fullest extent permitted by applicable law, survive the termination of
this Agreement and remain in effect until the expiration of the relevant statutes of limitations. 

  
 6 

 4.5 Personnel Qualifications. MPL may utilize its own employees, the services of
Third Party contractors or Affiliates of MPC to provide the Management Services. MPL will use commercially reasonable efforts to establish and confirm that any such personnel are qualified to perform the Management Services in accordance with
MPL’s ordinary standards applicable to similar services utilized in the management of its own operations. 
 ARTICLE 5

 BUDGETS AND EXPENDITURES 
 5.1 Operating and Capital Budgets. To the extent that MPL is required to review or approve, on behalf of MLH, any operating or capital expenditure budgets with respect to the MLH Pipelines, MPL
must first obtain MLH’s prior consent before reviewing or approving such budgets. MPL will provide to MLH all expense budgets, capital budgets and forecasted statements of income and cash flow prepared by the co-owners and/or operators of the
MLH Pipelines. 
 5.2 Emergency Expenditures. MPL, on behalf of MLH, shall be responsible for handling emergencies
occurring with respect to the MLH Pipelines. In cases of emergency, MPL may authorize expenditures for required work when such is necessary in MPL’s good faith judgment to respond to the emergency or to mitigate damage or danger to persons,
property or the environment, without the necessity of submitting such proposed expenditures in advance for approval by MLH. In such event, MPL shall, as soon as practicable, by telephone notice or otherwise, inform the person designated by MLH of
the existence or occurrence of the emergency, the full particulars thereof, the corrective action being taken or proposed and the estimated cost, if known. Such notice shall be confirmed in writing as soon as practicable. MPL shall directly charge
MLH for its costs and expenses, including those costs and expenses attributable to Affiliates or Third Party contractors utilized by MPL. 
 5.3 Special Assignments. If MLH requests MPL to perform any activity beyond the scope of the Management Services (a “Special Assignment”), and MPL agrees to that request, the costs
and expenses therefor shall be paid by MPL and shall be reimbursed by MLH. 
 ARTICLE 6 

ACCOUNTING 

6.1 Records. MPL will prepare and preserve, for and in the name of MLH, a complete set of operating, tax and financial records in
accordance with all applicable legal and industry standards. Such records will reflect any and all operating, tax and financial matters related to MLH’s investment in the MLH Pipelines and shall be kept separate from MPL’s internal records
and in a form and in a manner so that they are readily identifiable as belonging to MLH and can be accessed by MLH. MPL shall furnish all such information and reports as may be required for MLH’s internal purposes and by any federal or state
agency having appropriate jurisdiction. MLH and its duly authorized representatives may, at MLH’s option and at its sole expense at all reasonable times, but not more often than once in any calendar year, audit the books and records of MPL with
respect to the Management Services. Any audit of a particular calendar year must 

  
 7 

 
commence during the two-year period (or such longer period as the Parties may agree) following the end of such year. Nothing herein shall limit MLH’s ability to have full access, at all
reasonable times, to MLH’s books, accounts, records and all other documents, of whatever nature, in the possession or control of MPL, whether prepared by MPL or otherwise. 

6.2 Bank Accounts. Separate bank accounts will be maintained by MLH, or in MLH’s name, into which all revenues and receipts
belonging to MLH shall be deposited and from which all payments on behalf of MLH shall be made. MPL shall have such authority as delegated by MLH, from time to time, to manage the day to day cash receipts and disbursements through the bank accounts
of MLH and to invest surplus funds from time to time, all in accordance with guidelines approved by MLH. 
 ARTICLE 7

 CONFIDENTIALITY 
 7.1 Confidentiality. 
 (a) From and after the Effective Date, each Party
shall hold, and shall cause their respective Subsidiaries and Affiliates and its and their directors, managers, officers, employees, agents, consultants, advisors, and other representatives (collectively, “Representatives”) to hold
all Confidential Information of the other Party, in strict confidence, with at least the same degree of care that applies to such Party’s confidential and proprietary information and shall not use such Confidential Information except in
connection with its performance or acceptance of services hereunder and shall not release or disclose such Confidential Information to any other Person, except its Representatives. Each Party shall be responsible for any breach of this section by
any of its Representatives. 
 (b) If a Party receives a subpoena or other demand for disclosure of Confidential Information
received from any other Party or must disclose to a governmental authority any Confidential Information received from such other Party in order to obtain or maintain any required governmental approval, the receiving Party shall, to the extent
legally permissible, provide notice to the providing Party before disclosing such Confidential Information. Upon receipt of such notice, the providing Party shall promptly either seek an appropriate protective order, waive the receiving Party’s
confidentiality obligations hereunder to the extent necessary to permit the receiving Party to respond to the demand, or otherwise fully satisfy the subpoena or demand or the requirements of the applicable governmental authority. If the receiving
Party is nonetheless legally compelled to disclose such Confidential Information or if the providing Party does not promptly respond as contemplated by this section, the receiving Party may disclose that portion of Confidential Information covered
by the notice or demand. 
 (c) Each Party acknowledges that the disclosing Party would not have an adequate remedy at law for
the breach by the receiving Party of any one or more of the covenants contained in this Section 7.1 and agrees that, in the event of such breach, the disclosing Party may, in addition to the other remedies that may be available to it, to the
fullest extent permitted by law, apply to a court for an injunction to prevent breaches of this Section 7.1 and to enforce specifically the terms and provisions of this Section7.1. Notwithstanding any other section hereof, the provisions of
this Section7.1 shall survive the termination of this Agreement. 

  
 8 

 7.2 System Security. (a) If any Party is given access to another Party’s
computer systems or software (collectively, “Systems”) in connection with the Management Services, the Party given access (the “Availed Party”) shall comply with all of the other Party’s system security
policies, procedures and requirements that have been provided to the Availed Party in advance and in writing (collectively, the “Security Regulations”), and shall not tamper with, compromise or circumvent any security or audit
measures employed by such other Party. The Availed Party shall access and use only those Systems of the other Party for which it has been granted the right to access and use. 
 (b) Each Party shall use commercially reasonable efforts to ensure that only those of its personnel who are specifically authorized to have access to the Systems of the other Party gain such access, and
each Party shall use commercially reasonable efforts to prevent unauthorized access, use, destruction, alteration or loss of information contained in the Systems, including notifying its respective personnel of the restrictions set forth in this
Agreement and the Security Regulations. 
 (c) If, at any time, the Availed Party determines that any of its personnel has
sought to circumvent, or has circumvented, the Security Regulations, that any unauthorized Availed Party personnel have accessed the Systems, or that any of its personnel has engaged in activities that may lead to the unauthorized access, use,
destruction, alteration or loss of data, information or software of the other Party, the Availed Party shall promptly terminate any such person’s access to the Systems and promptly notify the other Party. In addition, such other Party shall
have the right to deny personnel of the Availed Party access to its Systems upon notice to the Availed Party in the event that the other Party reasonably believes that such personnel have engaged in any of the activities described in this
Section 7.2(c) or otherwise pose a security concern. The Availed Party shall use commercially reasonable efforts to cooperate with the other Party in investigating any apparent unauthorized access to such other Party’s Systems. 

ARTICLE 8

directors, managers, officers or employees. 
 8.3 Limitations and Liability. Each Party shall have a duty to mitigate
the Losses for which another is responsible hereunder. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL ANY PARTY OR ANY OF THEIR RESPECTIVE AFFILIATES BE LIABLE FOR ANY SPECIAL, INCIDENTAL, INDIRECT, CONSEQUENTIAL (INCLUDING
LOSS OF REVENUES OR PROFITS, LOSS OF DATA, LOSS OF GOODWILL AND LOSS OF CAPITAL, WHETHER OR NOT SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES), EXEMPLARY OR PUNITIVE DAMAGES OR THE LIKE (EXCEPT TO THE EXTENT THAT SUCH DAMAGES ARE
PAID TO A THIRD PARTY AS A RESULT OF A THIRD PARTY CLAIM) ARISING UNDER ANY LEGAL OR EQUITABLE THEORY OR ARISING UNDER OR IN CONNECTION WITH THIS AGREEMENT (OR THE PROVISION OF SERVICES HEREUNDER), ALL OF WHICH ARE HEREBY EXCLUDED BY AGREEMENT OF
THE PARTIES REGARDLESS OF WHETHER OR NOT ANY PARTY TO THIS AGREEMENT HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 
 8.4
Indemnification Is Exclusive Remedy. Except for equitable relief and rights pursuant to Article 7, to the fullest extent permitted by applicable law, the indemnification provisions of this Article 8 shall be the exclusive remedy for breach of
this Agreement. 
 8.5 Risk Allocation. Each Party agrees that the Management Fees charged under this Agreement reflect
the allocation of risk between the Parties, including the disclaimer of warranties in Section 3.2 and the limitations on liability in Section 8.3. Any modification of such allocation of risk from what is stated here would affect the
Management Fees charged and payable under this Agreement, and in consideration of such Management Fees, each Party hereby expressly agrees to such allocation of risk. 
 8.6 Indemnification Procedures. All claims for indemnification pursuant to this Article 8 shall be made in accordance with the provisions set forth in Section 2.5 of the Omnibus Agreement.
Notwithstanding anything to the contrary hereunder, no cause of action, dispute or claim for indemnification may be asserted against any Party or submitted to arbitration or legal proceedings which accrued more than two years after the later of
(a) the occurrence of the act or event giving rise to the underlying cause of action, dispute or claim and (b) the date on which such act or event was, or should have been, in the exercise of reasonable due diligence, discovered by the
Party asserting the cause of action, dispute or claim.

 10 

 9.2 Termination. Subject to the provisions of Section 9.4, a Party shall have
the right to terminate this Agreement effective upon delivery of written notice to the other Party: (a) if the other Party makes an assignment for the benefit of creditors, or becomes bankrupt or insolvent, or is petitioned into bankruptcy, or
takes advantage of any state, federal or foreign bankruptcy or insolvency act, or if a receiver or receiver/manager is appointed for all or any substantial part of its property and business and such receiver or receiver/manager remains undischarged
for a period of 30 days; (b) the other Party materially defaults in the performance of any of its covenants or obligations contained in this Agreement and such default is not remedied to the nondefaulting Party’s reasonable satisfaction
within 10 days with respect to a default of any payment obligation or 45 days with respect to the default of any other obligation contained in this Agreement, after receipt of written notice by the defaulting Party informing such Party of such
default, or if such default is not capable of being cured within 45 days, if the defaulting Party has not promptly begun to cure the default within such 45-day period and thereafter proceeded with all diligence to cure the same. 

9.3 Procedures on Termination. Following termination of this Agreement, (a) each Party will cooperate with the other Party as
reasonably necessary to avoid disruption of the ordinary course of the businesses of such other Party and its Affiliates and (b) MPL shall deliver to MLH, at the expense of MLH, the records maintained by MPL on behalf of MLH. MPL may make and
retain in its files one copy of such records. Termination of this Agreement shall not affect any Party’s right to payment for Management Services provided prior to the date of such termination. 

9.4 Effect of Termination. Upon termination of this Agreement, all rights and obligations of the Parties hereunder shall cease,
provided, however, that such termination shall not excuse any Party’s breach of this Agreement prior to termination; provided further, that Article 4 (solely with respect to fees and Third Party costs and expenses incurred
or attributable to periods prior to termination), Article 7, Article 8 and this Article 9 shall, to the fullest extent permitted by applicable law, survive any termination of this Agreement. 

ARTICLE 10 

MISCELLANEOUS 
 10.1 Entire Agreement. This Agreement constitutes the entire agreement between the Parties with respect to the subject matter of this Agreement, and supersedes all prior agreements, negotiations,
discussions, understandings and commitments, written or oral, between the Parties with respect to such subject matter. 
 10.2
Choice of Law; Mediation; Submission to Jurisdiction. 
 (a) This Agreement shall be governed by and construed in
accordance with the laws of the State of Delaware, without regard to principles of conflict of laws. The Parties hereby declare that it is their intention that this Agreement shall be regarded as made under the laws of the State of Delaware and that
the laws of said State shall be applied in interpreting its provisions 

  
 11 

 
in all cases where legal interpretation shall be required. Each of the Parties agrees (a) that this Agreement involves at least $100,000.00, and (b) that this Agreement has been entered
into by the Parties in express reliance upon 6 Del. C. § 2708. Each of the Parties hereby irrevocably and unconditionally agrees (i) to be subject to the exclusive jurisdiction of the courts of the State of Delaware and of the
federal courts sitting in the State of Delaware, and (ii) (A) to the extent such Party is not otherwise subject to service of process in the State of Delaware, to appoint and maintain an agent in the State of Delaware as such Party’s
agent for acceptance of legal process, and (B) that, to the fullest extent permitted by applicable law, service of process may also be made on such Party by prepaid certified mail with a proof of mailing receipt validated by the United States
Postal Service constituting evidence of valid service, and that service made pursuant to (b) (A) or (B) above shall, to the fullest extent permitted by applicable law, have the same legal force and effect as if served upon such Party
personally within the State of Delaware. The foregoing consents to jurisdiction and service of process shall not constitute general consents to service of process in the State of Delaware for any purpose except as provided herein and shall not be
deemed to confer rights on any person other than the Parties. 
 (b) If the Parties cannot resolve any dispute or claim arising
under this Agreement, then no earlier than 10 days nor more than 60 days following written notice to the other Parties, any Party may initiate mandatory, non-binding mediation hereunder by giving a notice of mediation (a “Mediation
Notice”) to the other Parties. In connection with any mediation pursuant to this Section 10.2, the mediator shall be jointly appointed by the Parties and the mediation shall be conducted in Findlay, Ohio unless otherwise agreed by the
Parties. All costs and expenses of the mediator appointed pursuant to this section shall be shared equally by the Parties. The then-current Model ADR Procedures for Mediation of Business Disputes of the Center for Public Resources, Inc., either as
written or as modified by mutual agreement of the Parties, shall govern any mediation pursuant to this section. In the mediation, each Party shall be represented by one or more senior representatives who shall have authority to resolve any disputes.
If a dispute has not been resolved within 30 days after the receipt of the Mediation Notice by a Party, then any Party may refer the resolution of the dispute to litigation. 
 10.3 Amendment. This Agreement may only be amended, modified or supplemented by a written instrument signed by an authorized representative of each of MPL and MLH. 

10.4 Waiver. Any term or provision of this Agreement may be waived, or the time for its performance may be extended, by the Party
or Parties entitled to the benefit thereof. Any such waiver shall be validly and sufficiently given for the purposes of this Agreement if, as to any Party, it is in writing signed by an authorized representative of such Party. The failure of any
Party to enforce at any time any provision of this Agreement shall not be construed to be a waiver of such provision, or in any way to affect the validity of this Agreement or any part hereof or the right of any Party thereafter to enforce each and
every such provision. No waiver of any breach of this Agreement shall be held to constitute a waiver of any other or subsequent breach. No single or partial exercise of any right or remedy under this Agreement precludes any simultaneous or
subsequent exercise of any other right, power or privilege. The rights and remedies set forth in this Agreement are not exclusive of, but are cumulative to, any rights or remedies now or subsequently existing at law, in equity or by statute.

  
 12 

 10.5 Partial Invalidity. Wherever possible, each provision hereof shall be
interpreted in such a manner as to be effective and valid under applicable law, but in case any one or more of the provisions contained herein shall, for any reason, be held to be invalid, illegal or unenforceable in any respect, such provision or
provisions shall be ineffective to the extent, but only to the extent, of such invalidity, illegality or unenforceability without invalidating the remainder of such provision or provisions or any other provisions hereof, unless such a construction
would be unreasonable. 
 10.6 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of
the Parties and their successors and permitted assigns; provided, however, that the rights and obligations of any Party under this Agreement shall not be assignable by such Party without the prior written consent of the other Party.
The successors and permitted assigns hereunder shall include any permitted assignee as well as the successors in interest to such permitted assignee (whether by merger, liquidation (including successive mergers or liquidations) or otherwise).

 10.7 Third Party Beneficiaries. Except to the extent otherwise provided in Article 8 with respect to the rights or the
MPL Indemnified Parties and the MLH Indemnified Parties, the provisions of this Agreement are solely for the benefit of the Parties and their respective successors and permitted assigns and shall not confer upon any Third Party any remedy, claim,
liability, reimbursement or other right in excess of those existing without reference to this Agreement.
