4. | EMPLOYMENT OF PERSONNEL; MANAGEMENT FEE

4.1 Personnel. Operator, or one of its Affiliates (other than MPC), shall employ or contract for such personnel as may be required by Operator to perform the Services. All such personnel, whether full or part-time, who are assigned to the Systems shall at all times remain employees of Operator, or its Affiliates, and shall be subject to their respective employer’s employee benefit plans and policies. Operator shall employ reasonable efforts to maintain the number of personnel performing Services for MPC at the optimum level and to keep them organized in a manner which will afford cost effective and efficient day-to-day operation of the Systems.

6

less than $11,195,500.00 per year. Should the scope of the Services performed by Operator significantly change during the Term, either Party may immediately notify the other Party, at which time the Parties will enter into good faith negotiations for a period of thirty (30) days to examine the change in scope of the Services and adjust the Management Fee accordingly. In the event the Parties, following such good faith negotiations, fail to agree on an appropriate adjustment to the Management Fee, either Party may terminate this Agreement without liability to the other Party.

4.4 Non-Operator Personnel. For the purpose of providing the Services, Operator may utilize its common law employees, the services of leased employees or third party contractors or Affiliates. If Operator uses third party contractors or Affiliates to provide such Services, Operator will insure that the same are qualified to perform the Services in accordance with Operator’s standards and that they coordinate all of their activities with Operator and keep Operator fully informed of their plans and activities sufficiently in advance for Operator to perform its obligations under this Agreement.

4.5 Liability for Compensation, Benefits, Severance and Taxes. MPC shall only be responsible for payment of Operator’s fees and expenses as set out in this Agreement. Operator shall ensure that all such personnel expenses incurred in connection with the personnel referred to in this Section 4 are paid, including compensation, salary, wages, overhead and administrative expenses incurred by Operator and its Affiliates and if applicable, social security, taxes, workers compensation insurance, benefits and other such expenses. Operator shall indemnify and save harmless MPC from all claims or liability for wages, salary, taxes or benefits in respect of Operator’s personnel.

5. | BUDGETS AND FORECAST OF REVENUE

5.1 Operating Budget and Capital Budget. In order to inform MPC as to the operating and capital expenditures contemplated for a forthcoming Calendar Year, to obtain MPC’s approval in respect thereof and to provide the authority to Operator to make certain extraordinary expenditures, an expense budget, a capital budget and a forecasted statement of income and cash flow shall be prepared annually for the Systems in consultation with MPC and presented to MPC for approval and utilized in accordance with the following:

(a) Preparation of Budgets and Presentation to MPC. Operator shall prepare and submit to MPC for review and approval, each Calendar Year in accordance with MPC’s budget and forecast timing requirements, an expense budget, a capital budget and a forecasted statement of income and cash flow, all to include the current and two (2) additional year forecasts. Such budgets shall set forth (i) the sums projected to be expended during the current Calendar Year, (ii) a proposed budget of the sums to be expended during the next Calendar Year, (iii) the sums it proposes to expend for such purposes during the next two Calendar Years following the budget year, and (iv) such other information as is reasonably requested by MPC. It is understood between MPC and Operator that Operator is preparing the budgets at the direction of MPC and that the Budgets are based on the most current information available to Operator both from its own knowledge of the Systems and from that knowledge supplied to Operator by MPC.

7

(b) Budget Amendments. Operator may propose amendments to any budget at any time by preparing a written budget amendment in a format similar to that described in Section 5.1(a) and by submitting it to MPC. MPC shall approve or deny any proposed amendments within thirty (30) days of submission to MPC.

(c) Prior Budget in Effect. Until any new expense budget, capital budget, or amendment thereto is approved by MPC, the prior budget shall remain in effect.

5.2 Emergency Expenditures. Operator shall be responsible for handling emergencies occurring with respect to the Systems. In cases of emergency, Operator may proceed with expenditures for required work when such is necessary in Operator’s good faith judgment to alleviate the emergency or to reduce or eliminate damage or danger to persons, property or the environment, without the necessity of submitting such proposed expenditures in advance for approval by MPC. In such emergency cases, Operator shall be allowed to use, in its good faith discretion, any of its or its Affiliates’ operating or administrative personnel to take corrective action, including without limitation, the use of emergency response service assets of Operator or its Affiliates or their emergency contract agents. Costs associated with such occurrence shall be billed directly to MPC and shall not be subject to any limitation set forth in Section 5 of this Agreement. In such event, Operator shall, as soon as practicable, by telephone notice or otherwise inform the person designated by MPC of the existence or occurrence of the emergency, full particulars thereof, the corrective action being taken or proposed and the estimated cost, as known. Such notice shall be confirmed in writing, as soon as practicable.

Operator has established an emergency response plan which will be provided to MPC. Operator shall comply with the plan terms and requirements in responding to one-call and emergency notifications received, and to emergency conditions indicated at MPL’s operations center.

6. | CASH DEFICIENCIES

If, at any time, Operator determines that MPC’s cash generations are insufficient to cover cash expenditures, including but not limited to, activities associated with the operation of the Systems as defined in this Agreement and Operator expenses chargeable to MPC, Operator will notify MPC as soon as possible. MPC shall advance to Operator on a timely basis, and in no event in more than ten (10) business days, monies in the aggregate sufficient to cover the costs incurred by Operator in the operation of the Systems. Nothing in this Section 6 is intended to authorize expenditures in excess of those authorized under this Agreement.

7. | ACCOUNTING

7.1 Records. Operator will prepare and preserve for and in the name of MPC a complete set of operating, tax and investment records in accordance with generally accepted accounting principles; and, in addition, will keep and maintain for MPC an accurate and complete set of books, records, and accounts which will reflect any and all financial transactions of MPC. Such records shall be kept in a form and in a manner so as to be able to

8

readily identify them as belonging to MPC, to be accessed by MPC and to allow them to be segregated from Operator’s records. Operator shall furnish all such information and reports as may be required for MPC’s meetings and by any federal or state agency having appropriate jurisdiction. MPC and its duly authorized representatives may, at its option and at its sole expense at all reasonable times, but not more often than once in any Calendar Year, audit the accounts of Operator for the operation of the Systems. Nothing herein shall limit MPC’s ability to have full access to MPC’s books, accounts, records and all other documents, in the possession or control of Operator, of whatever nature, whether prepared by Operator or otherwise, at all reasonable times.

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

7.2 Periodic Reports and Statements. Operator will analyze operating costs for control purposes, prepare cash and movements forecasts, and will furnish monthly financial statements and such other reports, statistics, and statements relative to the operation of the Systems as MPC may reasonably request or as may be required by its financial commitments now in existence or hereafter entered into. Operator will prepare and file or assist in the preparation and filing with the appropriate regulatory agencies, in the name of MPC, all reports required by law in connection with the ownership and operation of the Systems as provided in Section 3.1.

11

such other Party shall be entitled to participate in or, at such other Party’s option, assume control of the defense, appeal, settlement or remedial activities of such action, proceeding, claim, penalty or assessment with respect to which such indemnity has been invoked, and the Party that requested indemnification will fully cooperate with the other Party in connection therewith.

13. | FORCE MAJEURE

13.1 Effect of Force Majeure. (a) In the event that either MPC or Operator is rendered unable, by reason of an event of Force Majeure, to perform, wholly or in part, any obligation under this Agreement, then upon such Party’s giving notice and full particulars of such event as soon as practicable after the occurrence thereof, the obligations of both Parties, to the extent they are affected by such event of Force Majeure, except for unpaid financial obligations arising prior to such event of Force Majeure and except for Operator’s obligation to take steps to deal with any emergency in the Systems, shall be suspended to the extent and for the period of such Force Majeure condition.

12

(b) Non-Force Majeure Situations. Neither MPC nor Operator shall be entitled to the benefit of the provisions of Section 13.1(a) of this Agreement under the following circumstances:

(i) to the extent that the failure was caused by the Party claiming suspension having failed to remedy the condition by taking all reasonable acts, short of litigation, if such remedy requires litigation, and having failed to resume performance of such commitments or obligations with reasonable dispatch, provided, however, that neither Party shall be required to settle a labor dispute against its own better judgment;

(ii) if the failure was caused by failure of the Party claiming suspension to request or pay necessary funds in a timely manner, or with respect to the payment of any amounts then due hereunder; or

(iii) to the extent that the failure was caused or contributed to by gross negligence or willful misconduct of the Party claiming suspension.

(c) Resumption of Normal Performance. Should there be an event of Force Majeure affecting performance hereunder, the Parties shall cooperate, other than financially, to take all reasonable steps to remedy such event with all reasonable dispatch to insure resumption of normal performance.

If Operator is terminated under Section 15.2, Operator shall only be entitled to its Reimbursable Charges due or incurred to the date of termination.

15.3 Resignation by Operator. Operator may resign as Operator and this Agreement shall be terminated if:

(a) MPC shall neglect or fail to perform any or all of its material obligations under this Agreement and after thirty (30) days written notice of such default fails to rectify the same; or

(b) MPC becomes bankrupt or insolvent, commits or suffers any act of bankruptcy or insolvency, is placed in receivership, seeks debt or relief protection under any applicable legislation and such is not rectified within thirty (30) days from such event; or

(c) If MPC decides to terminate the operation of the Systems.

If Operator resigns under Section 15.3, then Operator shall be entitled to receive Reimbursable Charges due or incurred to the date of termination, and reimbursement of all costs and expenses incurred by Operator, including severance costs of direct charge position employees terminated as a result of the resignation, not otherwise reimbursed under Section 8 of this Agreement.

15.4 Nonapplicability. For greater certainty, it is understood and agreed that Sections 15.1 to 15.3 do not apply where this Agreement is terminated and Operator ceases to be Operator as a result of the termination of this Agreement pursuant to Section 2.2; in which case Operator shall be paid the Reimbursable Charges only up to the date of termination of this Agreement.

16.5 Confidentiality. Each Party acknowledges that it may receive information from or regarding the other Party in the nature of trade secrets or that otherwise is confidential. Except as permitted herein, each Party agrees not to disclose to any third party (including any

15

Affiliates of such Party other than those Affiliates required by a Party to carry out such Party’s obligations hereunder and then only to the extent necessary) or to use except in furtherance of the purposes and objectives of this Agreement, any information it receives from or about the other Party that, if such information is in written form and is clearly designated as being confidential at the time of receipt, or, if such information is not in written form, is specifically designated as being confidential in a written notice received within thirty (30) days after the receipt of such information. Notwithstanding the foregoing, “confidential information” shall include customer-specific prices, cost or pricing formulas, descriptions of customer negotiations, or marketing and strategic plans of any other Party, other cost information, shipper information (including volumes and grade), contract terms (including the terms and provisions and existence of this Agreement), price information, and strategic or marketing methods or plans. All information not so designated or classified or not of the type described in the immediately preceding sentence, shall be deemed not to be confidential. Without the consent of the other Party, each Party agrees not to disclose to any third party (including such Party’s Affiliates other than those Affiliates required by a Party to carry out such Party’s obligations hereunder and then only to the extent necessary), other than in furtherance of the purposes and objectives of this Agreement, any such confidential information, except for disclosure (a) compelled by law (but the disclosing Party must notify the other Party promptly of any request for such information before disclosing it, if practicable), (b) to advisors, consultants or representatives of the applicable Party (provided that such persons agree in writing to maintain the confidentiality of such information), (c) of information that is or becomes available to the publicly generally (except through the breach of the provisions of this Agreement), or (d) of information a Party has also received from a source independent of the other Party and the receiving Party reasonably believes obtained that information without breach of any obligation of confidentiality. With respect to other information that is not specifically designated as being confidential or which otherwise pursuant to the terms hereof is confidential, it is the intent of the Parties that each Party should treat all such information regarding the other Party according to the same standard applied by such Party to similar information pertaining to its own business.

16.6 Waiver. No waiver by any Party of any default by any other Party in the performance of any provision, condition or requirement herein shall be deemed to be a waiver of, or in any manner release the other Party from, performance of any other provision, condition or requirement herein, nor shall such waiver be deemed to be a waiver of, o: in any manner a release of, the other Party from future performance of the same provision, condition or requirement. Any delay or omission of any Party to exercise any right hereunder shall not impair the exercise of any such right, or any like right, accruing to it thereafter. No waiver of a right created by this Agreement by one Party shall constitute a waiver of such right by the other Party except as may otherwise be required by law with respect to persons not Parties hereto. The failure of one Party to perform its obligations hereunder shall not release the other Party from the performance of such obligations.

16.7 Severability. Should any provision of this Agreement be deemed in contradiction with the laws of any jurisdiction in which it is to be performed or unenforceable for any reason, such provision shall be deemed null and void, but this Agreement shall remain in force in all other respects. Should any provision of this Agreement be or become ineffective

16

because of changes in applicable laws or interpretations thereof or should this Agreement fail to include a provision that is required as a matter of law, the validity of the other provisions of this Agreement shall not be affected thereby. If such circumstances arise, the Parties hereto shall negotiate in good faith appropriate modifications to this Agreement to reflect those changes that are required by law.
