applicable laws, regulations, permit conditions, or agreements; 

  
 3 








 (b) promptly pay and discharge, for and in the name of HSH, all expenses, costs and

of the appropriate governmental authorities. Notwithstanding anything herein to the contrary, MPL has no duty to advance funds on behalf of HSH in the performance of its duties under this Agreement, but MPL shall notify HSH if any insufficiency of
funds exists.

 3.2 Disclaimer of Warranties. Except as expressly set forth in this Agreement:
(a) HSH acknowledges and agrees that MPL makes no warranties of any kind with respect to the Management Services; and (b) MPL expressly disclaims all warranties, expressed or implied, of any kind with respect to the Management Services,
including any warranty of non-infringement, merchantability, fitness for a particular purpose or conformity to any representation or description as to the Management 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. 
 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 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. HSH 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 HSH 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 HSH to
such subcontractors; provided, however, that MPL shall not be responsible for the amount of fees paid by HSH 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. 

  
 5 








 3.4 No Partnership. Nothing in this Agreement will be deemed to create a partnership,
joint venture or similar relationship between HSH and MPL, and neither MPL nor any of its Affiliates has any power to bind HSH. 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 HSH or any HSH Affiliated Entity. 

4.2 Management Fee. MPL shall be paid a management fee (the “Management Fee”) of $42,000 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. HSH shall reimburse MPL for any expenditures made by MPL on
behalf of HSH under Section 5.2 or otherwise with the consent of HSH within 30 days of receipt by HSH 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, HSH agrees to reimburse MPL for the
additional taxes due from MPL, including any interest and 

  
 6 








 
penalties. HSH shall have the right to contest with the applicable tax authority, at HSH’s sole expense, the amount of any taxes or the result of any audit. MPL will be responsible for
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 survive the termination of this Agreement and remain in effect until the
expiration of the relevant statutes of limitations. 
 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 HSH, any operating or capital expenditure budgets with respect to the HSH Pipelines, MPL
must first obtain HSH’s prior consent before creating, reviewing or approving such budgets. MPL will provide to HSH all expense budgets, capital budgets and forecasted statements of income and cash flow prepared by the co-owners and/or
operators of the HSH Pipelines. 
 5.2 Emergency Expenditures. MPL, on behalf of HSH, shall be responsible for handling
emergencies occurring with respect to the HSH 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 HSH. In such event, MPL shall, as soon as practicable, by telephone notice or otherwise, inform the person designated by
HSH 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 HSH 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 HSH 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 HSH. 
 ARTICLE 6 

ACCOUNTING 

6.1 Records. MPL will prepare and preserve, for and in the name of HSH, 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 HSH’s investment in the HSH 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 HSH and can 

  
 7 








 
be accessed by HSH. MPL shall furnish all such information and reports as may be required for HSH’s internal purposes and by any federal or state agency having appropriate jurisdiction. HSH
and its duly authorized representatives may, at HSH’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 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 HSH’s ability to have full access, at all reasonable times,
to HSH’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 HSH, or in HSH’s name, into which all revenues and receipts belonging to HSH shall be deposited and from which all payments on
behalf of HSH shall be made. MPL shall have such authority as delegated by HSH, from time to time, to manage the day to day cash receipts and disbursements through the bank accounts of HSH and to invest surplus funds from time to time, all in
accordance with guidelines approved by HSH. 
 ARTICLE 7

 (a) From and after the Effective Date, each Party
shall hold, and shall cause its Subsidiaries and Affiliates and its and their directors, managers, officers, employees, agents, consultants, advisors, contractors, and other representatives (collectively, “Representatives”) to hold

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 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. 

  
 8 








 (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,
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 Section 7.1. Notwithstanding any other section hereof, the provisions of this Section 7.1 shall
survive the termination of this Agreement. 
 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 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 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 has 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.

 11 









 10.2 Choice of Law; Mediation; Submission to Jurisdiction. (a) This Agreement
shall be subject to and governed by the laws of the State of Delaware, excluding any conflicts-of-law rule or principle that might refer the construction or interpretation of this Agreement to the laws of another state. 

(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

 (c) Each Party agrees that

Section 10.8. 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. 
 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 HSH. 
 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.
