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. 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

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.

5

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 its MLH’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.

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 creating, 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.

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 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.

7

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.

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, 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.

(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.

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.
