PERFORMANCE OF SERVICES

3.1 General. (a) During the Term, and subject to the terms and conditions of this Agreement, MPLS will use commercially reasonable efforts to provide, or cause to be provided, on behalf of the GP and for the benefit of MPL and the MPL Affiliated Entities, the Services to MPL and the MPL 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 MPL’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 MPLS shall be under the direction, supervision and control of the GP.

(b) Notwithstanding anything to the contrary in this Agreement, neither MPLS 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) MPLS will provide such suitably qualified and experienced personnel to GP for the performance of Services as MPLS is able to make available to GP, and GP will have the right to approve such personnel. In the event that MPLS 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 MPL 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 MPL, then GP or MPL may provide written notice thereof to MPLS in accordance with Section 3.3. Upon receipt of such notice by MPLS, if MPLS 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 MPLS 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 MPL by Third Parties designated by MPLS. To the extent so provided, MPLS shall use commercially reasonable efforts to (i) cause such Third Parties to provide such Services under this Agreement and (ii) enable GP, MPL and the MPL 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 MPL; provided that MPLS 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 MPL acknowledge and agree that MPLS makes no warranties of any kind with respect to the Services; and (ii) MPLS 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 MPLS 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 MPL shall have the right, but not the obligation, to engage subcontractors to perform any such Services that MPLS is unable to provide for the duration of the Force Majeure Event; provided however, that any Fees paid or payable by MPL to MPLS 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 MPL to any subcontractors with respect to any Services that MPLS is unable to perform as a result of a Force Majeure Event. For the avoidance of doubt, if GP or MPL engages subcontractors to perform any Services during a Force Majeure Event, MPLS shall not be required to refund, or otherwise be liable for, any amounts in excess of the aggregate Fees paid or owed to MPLS 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 MPLS 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 MPL to obtain such Services.

ARTICLE V

FEES

5.1 Fees. GP and MPL shall pay MPLS 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, MPLS 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. MPLS 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, MPL agrees to reimburse MPLS for the additional taxes due from MPLS including interest and penalty. MPL shall have the right to contest with the tax authority at MPL’s sole expense the amount of any taxes or the result of any audit. MPLS 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 MPLS shall refund to GP or MPL 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 MPLS, such amounts due or advances made shall not be prorated or reduced and MPLS shall not be required to refund any prorated amount for such costs or expenses; and GP or MPL shall reimburse MPLS 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, MPLS will submit to MPL 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 MPL shall reimburse MPLS in accordance with this Article VI for all out-of-pocket costs and expenses actually paid by MPLS to Third Parties on behalf of MPL in connection with providing the Services (“Expenses”).

6.2 Timing of Payment; No Offsets. MPL will pay all amounts due pursuant to this Agreement within 10 days after the receipt of the invoice therefor. MPL shall not offset any amounts owing to it by MPLS or any of its Affiliates against amounts payable hereunder.

6.3 Non-Payment. If MPL 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, MPL 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 MPLS within 90 days following the end of the calendar year in which such Services were performed. MPL shall timely pay the disputed items in full while resolution of the dispute is pending; provided, however, that MPLS shall pay interest at the Default Rate on any amounts it is required to return to GP or MPL 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) MPL may, at its own cost and expense, audit (or cause an independent Third Party auditor to audit) the books and records of MPLS to the extent necessary to determine MPLS’s compliance with this Agreement with respect to Fees and Expenses charged or the performance of MPLS’s obligations under this Agreement. MPL 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 MPLS. MPL shall provide notice to MPLS 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 MPL may raise an objection pursuant to Section 6.4.

(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 MPLS’s right to terminate the employment relationship with any of its employees, or (ii) affecting the ability of any MPLS employee to be considered for transfers or promotions to positions listed on any internal job posting system.

7.3 Assets.

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, 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 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.

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)

13

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. THESE LIMITATIONS SHALL APPLY NOTWITHSTANDING ANY FAILURE OF ESSENTIAL PURPOSE OF ANY LIMITED REMEDY.

11.4 Indemnification Is Exclusive Remedy. Except for equitable relief and rights pursuant to Article VIII, to the fullest extent permitted by applicable law, the indemnification provisions of this Article XI shall be the exclusive remedy for breach of this Agreement.

11.5 Risk Allocation. Each Party agrees that the Fees charged under this Agreement reflect the allocation of risk between the Parties, including the disclaimer of warranties in Section 3.4(a) and the limitations on liability in Section 11.4. Modifying the allocation of risk from what is stated here would affect the Fees charged by MPLS, and in consideration of those Fees, each Party agrees to the stated allocation of risk.

11.6 Indemnification Procedures.

(a) The Indemnified Party agrees that within a reasonable period of time after it becomes aware of facts giving rise to a claim for indemnification under this Article XI, it will provide notice thereof in writing to the Indemnifying Party, specifying the nature of and specific basis for such claim to the extent then known by the Indemnified 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 with such defense and counterclaims, the making available to the Indemnifying Party of any files, records or other information of the Indemnified Party that the Indemnifying Party considers relevant to such defense and counterclaims, the making available to the Indemnifying Party of any employees of the Indemnified Party and the granting to the Indemnifying Party of reasonable access rights to

14

the properties and facilities of the Indemnified Party; provided, however, that in connection therewith the Indemnifying Party agrees to use reasonable efforts to minimize the impact thereof on the operations of the Indemnified Party and further agrees to maintain the confidentiality of all files, records, and other information furnished by the Indemnified Party pursuant to this Section 11.6. The obligation of the Indemnified Party to cooperate with the Indemnifying Party as set forth in the immediately preceding sentence shall not be construed as imposing upon the Indemnified Party an obligation to hire and pay for counsel in connection with the defense of and pursuit of any counterclaims with respect to any claims covered by the indemnification set forth in this Article XI; provided, however, that the Indemnified Party may, at its own option, cost and expense, hire and pay for counsel in connection with any such defense and counterclaims. The Indemnifying Party agrees to keep any such counsel hired by the Indemnified Party informed as to the status of any such defense, but the Indemnifying Party shall have the right to retain sole control over such defense and counterclaims.

(d) In determining the amount of any loss, cost, damage or expense for which the Indemnified Party is entitled to indemnification under this Agreement, the gross amount of the indemnification will be reduced by (i) any insurance proceeds realized by the Indemnified Party, and such correlative insurance benefit shall be net of any incremental insurance premium that becomes due and payable by the Indemnified Party as a result of such claim 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

12.1 Entire Agreement. This Agreement, including the Annexes hereto, 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.

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

15

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 12.2, 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.

12.3 Amendment. This Agreement may only be amended, modified or supplemented by a written instrument signed by an Authorized Representative of each of MPLS, GP and MPL.

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 or any other provisions hereof, unless such a construction would be unreasonable.

16

12.6 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 Parties.

Annex B

SERVICES AND FEES

The Fees for the Services will reflect the employee based costs incurred by MPLS to provide such Services plus an additional monthly cost. They will be calculated and paid in the following manner: As part of the monthly invoice, MPLS will show the employee salary and wage costs (including accruals) incurred for such month. The monthly invoice will be the sum of (a) the amount in the previous sentence, plus (b) employer payroll taxes for such month, plus (c) 1/12 of the estimated total benefits cost for the applicable calendar year, plus (d) the bonus accrual, including burden, for MPLS employees for such month, plus (e) the MPC stock-based compensation expense attributed to MPLS for such month, plus (f) $125,000.

At the end of each calendar quarter, MPLS will compare the latest projection of benefit costs to be charged for the year to the estimated total year cost charged under (b) above. The net value of this “true-up” (whether positive or negative) of these two amounts will be an adjustment to the remaining monthly invoices for the calendar year. At the end of each calendar quarter, MPLS will calculate a “true-up” of the total benefits cost charged for the year under (b) above compared to the actual cost of such benefits. The net value of such “true-up” (whether positive or negative) will be an adjustment to the December invoice to MPL.

For the month of the bonus payment (if any) to the MPLS employees, MPLS will calculate a “true-up” of the total bonus accrual charged for the year under (c) above compared to the actual cost of such bonus, excluding burden. The net value of such “true-up” (whether positive or negative) will be an adjustment to the next monthly invoice to MPL.

For the avoidance of doubt, the Parties agree that the Fees for the remainder of calendar month of the Effective Date will be calculated in the manner above and will be a pro-rata portion of such amounts based on the number of days remaining in such month from the Effective Date.

The Services will include the following, as required or requested by MPL:

1. Tariff administration: Making all tariff filings; monitoring and updating all tariff schedules, including joint tariffs; monitoring and advising on FERC and other regulatory impacts on tariffs and tariff procedures; advising management and customers on tariffs.
