Except as provided in the Operating Agreements, within one year after the Distribution Date, at their expense, the Marathon Oil Parties shall remove any and all exterior and interior commercial signs and similar identifiers on assets or properties owned or held by them that refer or pertain specifically to any Marathon Petroleum Party or the Marathon Petroleum Business. Notwithstanding the foregoing, Marathon Oil and Marathon Petroleum shall use commercially reasonable efforts to change all such references to the other Party as soon as practicable following the Distribution Date. Marathon Petroleum hereby grants to the Marathon Oil Parties, and Marathon Oil hereby grants to the Marathon Petroleum Parties, for a period of one year following the Distribution Date, a worldwide, non-exclusive, non-transferable, royalty-free license to use signs and identifiers that refer or pertain specifically to the other Party on the assets or properties used in the licensee’s respective businesses as of the Effective Time.

26

(b) Except as provided in the Operating Agreements and in Section 7.8(d) , after one year following the Distribution Date, (i) without the prior written consent of Marathon Oil, the Marathon Petroleum Parties shall not use or display any of the Marathon Oil Marks and (ii) without the prior written consent of Marathon Petroleum, the Marathon Oil Parties shall not use or display any of the Marathon Petroleum Marks; provided , however , that notwithstanding the foregoing, nothing contained in this Agreement will prevent any Party from using the other’s name in filings with Governmental Authorities, materials intended for distribution to such Party’s stockholders or any other communication (including correspondence) in any medium that describes the current or former relationship between the Parties; provided , further , that the continuation of references to such Marks in telephone directories (and other similar Third Party or incidental uses which are not capable of being updated within the time period set forth above) will not breach this Section 7.8 .

(c) The Parties agree that the names “Marathon Oil” and “Marathon Petroleum” are not variations of or confusingly similar with one another as between the Marathon Oil Business and the Marathon Petroleum Business as of the Effective Time. Each Party agrees that, if any authority that grants or registers either Marathon Oil Marks or corporation names or Marathon Petroleum Marks or corporation names objects to the registration of, or a court or arbitration panel questions or declines to enforce, a mark by a Party on the basis of similarity between the names “Marathon Oil” and “Marathon Petroleum,” so long as the Party attempting to register or enforce is not in violation of this Section 7.8 and is not using the mark within the scope of the other Party’s Business, the other Party shall offer commercially reasonable assistance in assuring the authority, court or panel that the proposed usage is not sufficiently similar to negate registration or enforcement.

(d) Any rights of any Marathon Oil Party to any Mark, other than for upstream oil and gas goods or services, that uses the letter M within a hexagon, is part of the Transferred Assets, and all rights thereto are hereby assigned to Marathon Petroleum. The Marathon Oil Parties hereby reserve and retain the right to use a mark with the letter M within a hexagon in commercial, upstream use at one location in each country but, after one year following the Distribution Date, shall not use such mark at more than one location in any country; provided , however , that continued Third-Party or incidental uses which are not capable of being updated within the time period set forth above will not breach the provisions of this Section 7.8 . Marathon Petroleum shall not use, register, or attempt to register a mark that uses the letter M within a hexagon for any upstream oil and gas goods or services, except as otherwise expressly set forth herein.

(e) Each Party shall use the Marks of the other Party as allowed hereunder only in connection with goods or services that are of a level of quality at least equal to the quality of comparable goods or services marketed by that Party before the Effective Time and that it will allow the Party owning the right to such Marks reasonable inspection rights, upon reasonable written notice, to ensure compliance with the foregoing.

(f) Should a Party cease to use for 12 months, in any country, a Mark which such Party owns and which uses the name “Marathon” or the letter M within a hexagon, such Party hereby does (and shall execute, upon the other Party’s written request, such other documentation as may be reasonably necessary to) assign such Mark in such country to the other Party. This

27

obligation applies regardless of the reason for cessation, whether because of acquisition, insolvency or otherwise. The assignee shall pay to the assignor as consideration the cost of maintaining such mark for the shortest period of protection in the relevant country.

(g) A Party shall use commercially reasonable efforts to inform the other Party if the first Party becomes aware of a Third Party infringing the second Party’s mark which uses the name “Marathon” or the letter M within a hexagon. Each Party shall use reasonable efforts to enforce its marks which use the name “Marathon” or the letter M within a hexagon so as to avoid dilution of the other Party’s marks.

(h) Marathon Oil is and will remain the registrant and owner of the domain name “MARATHON.COM”. Marathon Oil will have the right to designate the administrative, technical and billing contacts for the domain name, to change registrars, and to change the registrar’s records. Subject to the following provisions of this Section 7.8(h), for a period of [    ] following the Effective Time, Marathon Oil shall use commercially reasonable efforts to maintain a default file at this domain (named “index.html”), the primary purpose of which will be to re-direct persons accessing MARATHON.COM to the primary domain for Marathon Petroleum and the primary domain for Marathon Oil. Such re-direction will be the only use for MARATHON.COM other than primarily administrative functions (such as terms of use, privacy statements, copyright statements, and contact information) that may be appropriate according to law or industry practice. Neither Party’s primary domain will be MARATHON.COM. Neither Party will use or permit use of MARATHON.COM in an email address or other than as set forth herein. Marathon Petroleum hereby grants to Marathon Oil a limited, royalty-free license to use the trade names and trademarks of Marathon Petroleum as part of its maintenance of the domain name MARATHON.COM , pursuant to Marathon Petroleum’s reasonable guidelines and for the sole purpose of providing such re-direction. If Marathon Oil and its Affiliates, successors and assigns stop using “Marathon” in or as a registered trade name, trademark or service mark for a period of 12 consecutive months, Marathon Oil shall transfer the domain name to Marathon Petroleum for no more consideration than the reasonable expenses of such transfer and, upon such transfer, Marathon Petroleum will have an unrestricted right to use, sell, license, or assign the domain name “MARATHON.COM” at the sole discretion of Marathon Petroleum and this paragraph will otherwise cease to be effective. If Marathon Petroleum and its Affiliates, successors and assigns stop using “Marathon” in or as a registered trade name, trademark or service mark for a period of 12 consecutive months, Marathon Oil will have an unrestricted right to use, sell, license, or assign the domain name “MARATHON.COM” at the sole discretion of Marathon Oil and this paragraph will otherwise cease to be effective. If, at any time after the Effective Time, Marathon Oil and its Affiliates, successors and assigns discontinue the use of the domain name, MARATHON.COM (other than as a result of an Internet service interruption or other temporary condition or set of circumstances), then Marathon Oil shall, if requested by Marathon Petroleum in accordance with Section 14.9 within 90 days of such discontinuance, transfer the domain name to Marathon Petroleum for no more consideration than the reasonable expenses of such transfer and, upon such transfer, Marathon Petroleum will have an unrestricted right to use, sell, license, or assign the domain name “MARATHON.COM” at the sole discretion of Marathon Petroleum and this paragraph will otherwise cease to be effective.

(i) Marathon Oil is and will remain the owner of each of the domain names and Twitter accounts listed on Schedule 7.8(A) , and Marathon Petroleum hereby transfers, and

28

agrees to cause each of the other Marathon Petroleum Parties to transfer, to Marathon Oil (or to such other Marathon Oil Parties as Marathon Oil may designate) all of the respective rights, titles and interests of the Marathon Petroleum Parties in and to such domain names and accounts, effective as of the Effective Time. Marathon Petroleum is and will remain the owner of each of the domain names listed on Schedule 7.8(B) , and Marathon Oil hereby transfers, and agrees to cause each of the other Marathon Oil Parties to transfer, to Marathon Petroleum (or to such other Marathon Petroleum Parties as Marathon Petroleum may designate) all of the respective rights, titles and interests of the Marathon Oil Parties in and to such domain names, effective as of the Effective Time.

(j) Without limiting the generality of the provisions of Section 3.4 , as of the Effective Time, the Trademark License Agreement dated as of January 1, 1998 between Marathon Oil Company and Marathon Ashland Petroleum LLC shall be terminated.

SECTION 7.9 Stock Options Registration Statement . Marathon Petroleum shall prepare and, if required, file with the SEC such amendments and supplements to the Stock Options Registration Statement (and the prospectus used in connection therewith) as may be necessary to keep the Stock Options Registration Statement effective under the Securities Act for a period of not less than ten years following the Distribution Date, provided that Marathon Petroleum’s obligations pursuant to this Section 7.9 shall terminate on the date upon which there are no further offers of securities covered thereby pursuant to the terms of the applicable stock option agreements.

32

Losses with respect to the Marathon Petroleum Business and the Transferred Assets under Marathon Oil Policies that provide coverage for such Losses (excluding, for the avoidance of doubt, any group health and welfare insurance policies) (“Shared Policies”) with insurers that are “occurrence-based” insurance policies (“Occurrence-Based Policies”) arising out of insured events commencing from the date of coverage thereunder to the extent that the terms and conditions of any such Occurrence-Based Policies and agreements relating thereto so allow; and (ii) subject to the provisions of Section 9.5(e) , Marathon Petroleum will have the right to assert and/or continue to prosecute claims for any Losses with respect to the Marathon Petroleum Business and the Transferred Assets under Shared Policies with insurers that are written on a “claims-made” basis (“Claims-Made Policies”) arising out of insured events commencing from the date of coverage thereunder to the extent that the terms and conditions of any such Claims-Made Policies and agreements relating thereto so allow.

No Marathon Oil Party will bear any Liability for the failure of an insurer to pay any claim under any Shared Policy. It is understood that Claims-Made Policies may not provide coverage to the Marathon Petroleum Parties for incidents occurring prior to the Effective Time but asserted with the insurance carrier after the Effective Time.

(e) In the event that after the Effective Time Marathon Oil proposes to amend, commute, terminate, buy-out, extinguish liability under or otherwise modify any Shared Policies under which Marathon Petroleum has or may in the future have rights to assert claims pursuant

33

to this Article IX in a manner that would reasonably be expected to adversely affect any such rights of Marathon Petroleum in any material respect, (i) Marathon Oil will give Marathon Petroleum prior notice thereof and consult with Marathon Petroleum with respect to such action, (ii) Marathon Oil will not take such action without the prior written consent of Marathon Petroleum, such consent not to be unreasonably withheld, conditioned or delayed, and (iii) Marathon Oil will pay to Marathon Petroleum its equitable share (which shall be mutually agreed upon by Marathon Oil and Marathon Petroleum, acting reasonably), if any, of any net proceeds actually received by Marathon Oil from the insurer under the applicable Shared Policy as a result of such action by Marathon Oil (after deducting Marathon Oil’s Out-of-Pocket Expenses incurred in connection with such action).

(f) To the extent that the limits of any Shared Policy preclude payment in full of Unrelated Claims filed by Marathon Oil and Marathon Petroleum, the insurance proceeds available under such Shared Policy shall be paid to Marathon Oil and/or Marathon Petroleum on a FIFO Basis. In the event that Marathon Oil and Marathon Petroleum file Related Claims under any Shared Policy, each of Marathon Oil and Marathon Petroleum shall receive a pro rata amount of the available insurance proceeds, based on the relationship the Loss incurred by each such Party bears to the total Loss to both such Parties from the occurrence or event underlying the Related Claims.

(g) In no event will any Marathon Oil Party have any liability or obligation whatsoever to any Marathon Petroleum Party if any Shared Policy is terminated or otherwise ceases to be in effect for any reason (other than a termination in breach of Section 9.5(e) ), is unavailable or inadequate to cover any Liability of any Marathon Petroleum Party for any reason whatsoever or is not renewed or extended beyond the current expiration date.

From and after the Effective Time, Marathon Oil will pay all premiums, taxes, assessments or similar charges (retrospectively-rated or otherwise) as required under the terms and conditions of the respective Shared Policies in respect of periods of coverage prior to the Effective Time, whereupon Marathon Petroleum will upon the request of Marathon Oil promptly reimburse Marathon Oil for that portion of such additional premiums and other payments paid by Marathon Oil as are reasonably determined by Marathon Oil to be attributable to the Marathon Petroleum Business, provided that, prior to agreeing to pay any such additional premiums or other payments that would reasonably be expected to result in a requirement for Marathon Petroleum to provide reimbursement under this Section 9.7 , Marathon

34

Oil shall, to the extent reasonably practicable, provide Marathon Petroleum with prior notice and a reasonable opportunity to consult with Marathon Oil with respect thereto. Notwithstanding the foregoing, Marathon Oil will distribute any return of premiums, taxes, assessments or similar charges (retrospectively-rated or otherwise) under the terms and conditions of the respective Shared Policies, to Marathon Petroleum in proportion to the amount of any such return previously allocated to Marathon Petroleum.

SECTION 9.8 Agreement for Waiver of Conflict and Shared Defense . In the event that a Shared Policy provides coverage for both a Marathon Oil Party, on the one hand, and a Marathon Petroleum Party, on the other hand, relating to the same occurrence, Marathon Oil and Marathon Petroleum agree to defend jointly, pursuant to the Joint Defense Agreement, provided that in the event there is a conflict of interest which in the reasonable opinion of either such Party would otherwise prevent the conduct of that joint defense, the Parties shall cooperate to pursue coverage under such Shared Policy pursuant to appropriate arrangements (which may require separate counsel) as permitted by such Shared Policy. Nothing in this Section 9.8 will be construed to limit or otherwise alter in any way the indemnity obligations of the Parties, including those created by this Agreement, by operation of law or otherwise.

SECTION 9.9 Duty to Mitigate . To the extent that any Party is responsible for the Claims Administration for any claim under any of the Shared Policies after the Effective Time, such Party shall use its commercially reasonable efforts to mitigate the amount of the Loss which is the subject of the claim under the applicable Shared Policy.

An insurance carrier that would otherwise be obligated to pay any claim shall not be relieved of the responsibility with respect thereto, or, solely by virtue of the provisions of this Article IX , have any subrogation rights with respect thereto, it being expressly understood and agreed that no insurance carrier or any Third Party shall be entitled to a benefit ( i.e ., a benefit such Person would not be entitled to receive had the Distribution not occurred or in the absence of the provisions of this Article IX ) by virtue of the provisions hereof.

(g) any action or inaction by any Marathon Petroleum Party that results, directly or indirectly, in a breach of any of the covenants of Marathon Oil contained in, or a breach by Marathon Oil or other failure of Marathon Oil to comply with, or a default or event of default under, (i) the Series 2007A fixed rate tax-exempt revenue bonds issued by the Parish of St. John the Baptist, State of Louisiana, (ii) the Installment Sale Agreement dated as of May 1, 2007 between the Parish of St. John the Baptist, State of Louisiana, and Marathon Oil, or (ii) any related agreements, certifications or other documents;

(h) any item or matter for which indemnification is to be provided by Marathon Petroleum in accordance with Article XV of the Employee Matters Agreement; and

(i) any Marathon Petroleum Financial Instrument;

38

in each case, regardless of when or where the loss, claim, accident, occurrence, event or happening giving rise to the Expense or Loss took place, or whether any such loss, claim, accident, occurrence, event or happening is known or unknown, or reported or unreported and regardless of whether such loss, claim, accident, occurrence, event or happening giving rise to the Expense or Loss existed prior to, on or after the Distribution Date or relates to, arises out of or results from actions, inactions, events, omissions, conditions, facts or circumstances occurring or existing prior to, on or after the Distribution Date.

SECTION 11.3 Indemnification by Marathon Oil . Except as provided in Section 11.5, as expressly provided in any of the Operating Agreements, Marathon Oil shall indemnify, defend and hold harmless the Marathon Petroleum Parties and each of their respective Affiliates, directors, officers, employees and agents, and each of the heirs, executors, successors and assigns of any of the foregoing (collectively, the “Marathon Petroleum Indemnified Parties”), from and against any and all Expenses or Losses to the extent incurred or suffered by one or more of the Marathon Petroleum Indemnified Parties in connection with, relating to, arising out of or due to, directly or indirectly, any of the following items:

(a) the failure by any Marathon Oil Party or any other Person to pay, perform or otherwise promptly discharge any of the Marathon Oil Liabilities in accordance with their respective terms;

(b) any Marathon Oil Liability;

(c) the Marathon Oil Business;

(d) solely with respect to the information contained in the Information Statement under the caption “The Spin-off – Reasons for the Spin-Off” and the information contained in the reports of Marathon Oil filed with the SEC under the Exchange Act and incorporated by reference in the Notes Offering Memorandum (collectively, the “Designated Marathon Information”), any untrue statement or alleged untrue statement of a material fact or omission or alleged omission to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading;

(e) any use by any Marathon Oil Party allowed hereunder after the Effective Time of the Marathon Petroleum Marks or the Information owned by, or licensed by a Third Party to, a Marathon Petroleum Party;

(f) the breach by any Marathon Oil Party of any covenant or agreement set forth in this Agreement or any Conveyancing Instrument;

(g) any item or matter for which indemnification is to be provided by Marathon Oil in accordance with Article XV of the Employee Matters Agreement; and

in each case, regardless of when or where the loss, claim, accident, occurrence, event or happening giving rise to the Expense or Loss took place, or whether any such loss, claim,

39

accident, occurrence, event or happening is known or unknown, or reported or unreported and regardless of whether such loss, claim, accident, occurrence, event or happening giving rise to the Expense or Loss existed prior to, on or after the Distribution Date or relates to, arises out of or results from actions, inactions, events, omissions, conditions, facts or circumstances occurring or existing prior to, on or after the Distribution Date.

SECTION 11.4 Applicability of and Limitation on Indemnification . The indemnity obligations under this Article XI shall apply notwithstanding any investigation made by or on behalf of any Indemnified Party and shall apply without regard to whether the Loss or Expense for which indemnity is claimed hereunder is based on strict liability, absolute liability or any other theory of liability or arises as an obligation for contribution. THE PARTIES UNDERSTAND AND AGREE THAT THE RELEASE FROM LIABILITIES AND INDEMNIFICATION OBLIGATIONS HEREUNDER AND UNDER THE OPERATING AGREEMENTS MAY INCLUDE RELEASE FROM LIABILITIES AND INDEMNIFICATION FOR LOSSES RESULTING FROM, OR ARISING OUT OF, DIRECTLY OR INDIRECTLY AND IN WHOLE OR IN PART, AN INDEMNITEE’S OWN NEGLIGENCE, STRICT LIABILITY OR OTHER LEGAL FAULT.

SECTION 11.5 Adjustment of Indemnifiable Losses .

(a) The amount that any Party (an “Indemnifying Party”) is required to pay to any Person entitled to indemnification hereunder (an “Indemnified Party”) shall be reduced by any insurance proceeds and other amounts actually recovered (net of any Out-of-Pocket Expenses incurred in the collection thereof) by or on behalf of such Indemnified Party in reduction of the related Expense or Loss. Each of Marathon Oil and Marathon Petroleum shall use its respective commercially reasonable efforts to collect any proceeds under its respective available and applicable insurance policies to which it or any of its Subsidiaries is entitled prior to seeking indemnification or contribution under this Agreement, where allowed; provided, however , that any such actions by an Indemnified Party will not relieve the Indemnifying Party of any of its obligations under this Agreement, including the Indemnifying Party’s obligation promptly to pay directly or reimburse the Indemnified Party for costs and expenses actually incurred by the Indemnified Party. If an Indemnified Party receives a payment (an “Indemnity Payment”) required by this Agreement from an Indemnifying Party in respect of any Expense or Loss and subsequently actually receives insurance proceeds or indemnification proceeds from any Third Party in respect of such Expense or Loss, then such Indemnified Party shall refund to the Indemnifying Party an amount equal to the lesser of (i) the after-tax amount of such insurance proceeds or indemnification proceeds actually received and (ii) the net amount of Indemnity Payments actually received previously. The Indemnified Party agrees that the Indemnifying Party shall be subrogated to such Indemnified Party under any applicable insurance policy as to any payments made by such Indemnifying Party.

(b) An insurer who would otherwise be obligated to pay any claim shall not be relieved of the responsibility with respect thereto or, solely by virtue of the indemnification provisions hereof, have any subrogation rights with respect thereto, it being expressly understood and agreed that no insurer or any other Third Party shall be entitled to a “windfall” ( i.e. , a benefit it would not be entitled to receive in the absence of the indemnification provisions), and shall not be deemed to be third-party beneficiaries, by virtue of the indemnification provisions hereof.

40

(c) To the extent permissible under applicable tax law, amounts paid by Marathon Oil to or for the benefit of Marathon Petroleum or by Marathon Petroleum to or for the benefit of Marathon Oil under this Article XI (and under other specified provisions of this Agreement) shall be treated by the Parties and their respective Subsidiaries, for all applicable tax purposes, as either a contribution by Marathon Oil to Marathon Petroleum or a distribution by Marathon Petroleum to Marathon Oil, as the case may be, occurring immediately prior to the Distribution; provided, however, that, in the event it is determined that such treatment is not permissible under applicable law, the payment in question shall be adjusted to place the Indemnified Party in the same after-tax position it would have enjoyed if such treatment had been permissible.

(d) In the event that an Indemnity Payment shall be denominated in a currency other than United States dollars, the amount of such payment shall be translated into United States dollars using the Foreign Exchange Rate for such currency determined in accordance with the following rules:

(i) with respect to an Expense or a Loss arising from payment by a financial institution under a guarantee, comfort letter, letter of credit, foreign exchange contract or similar instrument, the Foreign Exchange Rate for such currency shall be determined as of the date on which such financial institution shall have been reimbursed;

(ii) with respect to an Expense or a Loss covered by insurance, the Foreign Exchange Rate for such currency shall be the Foreign Exchange Rate employed by the insurance company providing such insurance in settling such Expense or Loss with the Indemnifying Party; and

(iii) with respect to an Expense or a Loss not covered by clause (i) or (ii) above, the Foreign Exchange Rate for such currency shall be determined as of the date that notice of the claim with respect to such Expense or Loss shall be given to the Indemnified Party.

SECTION 11.6 Procedures for Indemnification of Third-Party Claims .

(a) If any Third Party shall make any claim or commence any Action (each such claim or Action being a “Third-Party Claim”) against any one or more of the Indemnified Parties with respect to which an Indemnified Party intends to make any claim for indemnification against Marathon Petroleum under Section 11.2 or against Marathon Oil under Section 12.3 , such Indemnified Party shall promptly, but in no event later than 10 days after receipt by the Indemnified Party of written notice of the Third-Party Claim, give written notice to the Indemnifying Party describing such Third-Party Claim in reasonable detail. Notwithstanding the foregoing, the failure of any Indemnified Party to provide notice in accordance with this Section 11.6(a) shall not relieve the related Indemnifying Party of its obligations under this Article XI , except to the extent that such Indemnifying Party is actually prejudiced by such failure to provide prompt notice.

(b) The Indemnifying Party shall have 21 days after its receipt of the notice referred to in Section 11.6(a) to notify the Indemnified Party that it elects to conduct and control the defense of such Third-Party Claim. If the Indemnifying Party does not give the foregoing notice,

41

the Indemnified Party shall have the right to defend, contest, settle or compromise such Third-Party Claim in the exercise of its reasonable discretion, subject to the provisions of this Section 11.6 , and the Indemnifying Party shall, upon request from any of the Indemnified Parties, promptly pay to such Indemnified Parties in accordance with the other terms of this Section 11.6(b) the amount of any Expense or Loss subject to indemnification hereunder resulting from the Third-Party Claim. If the Indemnifying Party gives the foregoing notice that it elects to conduct and control the defense of such Third-Party Claim, the Indemnifying Party shall have the right, at its sole expense, to undertake, conduct and control, through counsel reasonably acceptable to the Indemnified Party, the conduct and settlement of such Third-Party Claim, and the Indemnified Party shall cooperate with the Indemnifying Party in connection therewith, provided that: (i) the Indemnifying Party shall use its reasonable best efforts to prevent any lien, encumbrance or other adverse charge to thereafter attach to any asset of any Indemnified Party; (ii) the Indemnifying Party shall use its reasonable best efforts to prevent any injunction against any Indemnified Party; (iii) the Indemnifying Party shall permit the Indemnified Party and any counsel chosen by the Indemnified Party and reasonably acceptable to the Indemnifying Party to monitor such conduct or settlement and shall provide the Indemnified Party and any such counsel with such information regarding such Third-Party Claim as either of them may reasonably request (which request may be general or specific), but the fees and expenses of such counsel chosen by the Indemnified Party shall be borne by the Indemnified Party unless (A) the Indemnifying Party and the Indemnified Party shall have mutually agreed that the Indemnifying Party should pay for such counsel or (B) the named parties to any such Third-Party Claim include the Indemnified Party and the Indemnifying Party and representation of both parties by the same counsel would be inappropriate due to actual or reasonably likely conflicts of interest between them, in either of which cases the reasonable fees and disbursements of counsel for such Indemnified Party shall be paid or reimbursed by the Indemnifying Party; and (iv) the Indemnifying Party shall agree promptly to reimburse to the extent required under this Article XI the Indemnified Party for the full amount of any Expense or Loss resulting from such Third-Party Claim. A Party’s defense of any Third-Party Claim pursuant to Section 11.6(b) includes the right (after consultation with the other Party following at least 21 days’ written notice thereof) to compromise, settle or consent to the entry of any judgment or determination of liability concerning such Third-Party Claim; provided, however, that, in no event shall the Indemnifying Party, without the prior written consent of the Indemnified Party, settle or compromise any claim or consent to the entry of any judgment if the effect thereof is (i) to permit any injunction, declaratory judgment, other order or other non-monetary relief to be entered, directly or indirectly, against such Indemnified Party or (ii) in the reasonable judgment of such Indemnified Party (as reflected in a written objection delivered by such Indemnified Party to the Indemnifying Party within the period of 21 days following receipt of the written notice described above in this Section 11.6(b) ), have a material adverse financial impact or a material adverse effect upon the ongoing operations of such Indemnified Party (taken together with its Subsidiaries). Notwithstanding any other provision of this Section 11.6 , unless otherwise specifically agreed to by the Parties in writing (which agreement may not be unreasonably withheld, conditioned or delayed), neither Party shall enter into any compromise or settlement or consent to the entry of any judgment which does not include as an unconditional term thereof the giving by the Third Party of a release of both the Indemnitee and the Indemnifying Party (and their respective Subsidiaries) from all further liability concerning such Third-Party Claim.

42

(c) If the Indemnifying Party shall not have undertaken the conduct and control of the defense of any Third-Party Claim as provided above, the Indemnifying Party shall nevertheless be entitled through counsel chosen by the Indemnifying Party and reasonably acceptable to the Indemnified Party to monitor the conduct or settlement of such claim by the Indemnified Party, and the Indemnified Party shall provide the Indemnifying Party and such counsel with such information regarding such Third-Party Claim as either of them may reasonably request (which request may be general or specific), but all costs and expenses incurred in connection with such monitoring shall be borne by the Indemnifying Party. In any such case, the Indemnified Party shall have the right to compromise, settle or consent to the entry of any judgment with respect to such Third-Party Claim as provided in Section 11.6(b) without the consent of the Indemnifying Party.

(d) If the Indemnified Party determines in its reasonable judgment that the Indemnifying Party is not contesting such Third-Party Claim in good faith or is not settling such Third-Party Claim in accordance with this Section 11.6 , the Indemnified Party shall have the right to undertake control of the defense of such Third-Party Claim upon five days written notice to the Indemnifying Party and thereafter to defend, contest, settle or compromise such Third-Party Claim in the exercise of its exclusive discretion. In any such case, the Indemnified Party shall have the right to compromise, settle or consent to the entry of any judgment with respect to such Third-Party Claim as provided in Section 11.6(b) without the consent of the Indemnifying Party and at the sole expense of the Indemnifying Party.

(e) In the event of any payment by or on behalf of any Indemnifying Party to any Indemnified Party in connection with any Third-Party Claim, the Indemnifying Party will be subrogated to and will stand in the place of such Indemnified Party to the extent of such payment as to any events or circumstances in respect of which such Indemnified Party may have any right, defense or claim relating to the Third-Party Claim against any claimant or plaintiff asserting the Third-Party Claim or against any other Person (other than another Indemnified Party). Such Indemnified Party will cooperate with the Indemnifying Party in a reasonable manner, and at the cost and expense of the Indemnifying Party, in prosecuting any subrogated right, defense or claim.

(f) If an Action is commenced by a Third Party naming both one or more Marathon Oil Parties and one or more Marathon Petroleum Parties as defendants thereto, such Action will be handled in accordance with Section 7.7(b) , to the extent applicable. Except as provided in Section 11.8 , in the event of any Action in which the Indemnifying Party and the Indemnified Party each have Liability, then at the request of either Party, the Parties will endeavor to agree on an apportionment of Liability and Out-of-Pocket Expenses related to the defense of such Action. In the event of any Action in which the Indemnifying Party is not also a named defendant, at the request of either the Indemnified Party or Indemnifying Party, the Parties will use reasonable efforts to substitute the Indemnifying Party for the named defendant in the Action.

(g) With respect to any Proceeding (as defined in the Tax Sharing Agreement), the provisions of the Tax Sharing Agreement (and not the provisions of this Section 11.6 ) shall apply.

43

SECTION 11.7 Procedures for Indemnification of Direct Claims . If any claim for indemnification on account of an Expense or a Loss that does not result from a Third-Party Claim is to be made directly by the Indemnified Party against the Indemnifying Party, the Indemnified Party shall promptly after learning of such direct claim give written notice to the Indemnifying Party describing such claim in reasonable detail. Notwithstanding the foregoing, the failure of any Indemnified Party to provide notice in accordance with this Section 11.7 shall not relieve the Indemnifying Party of its obligations under this Article XI , except to the extent that such Indemnifying Party is actually prejudiced by such failure to provide prompt notice. Such notice may be given by email or other electronic means. Such Indemnifying Party shall have a period of 21 days after the receipt of such notice within which to respond thereto. If such Indemnifying Party does not respond within such 21-day period, such Indemnifying Party shall be deemed to have refused to accept responsibility to provide indemnification with respect to such claim. If such Indemnifying Party does not respond within such 21-day period or does respond within such 21-day period and rejects such claim in whole or in part, such Indemnified Party shall be free to pursue resolution as provided in Article XII .

SECTION 11.8 Contribution . If the indemnification provided for in this Article XI is judicially determined to be unavailable (other than in accordance with the terms of this Agreement, in which case this Section 11.8 shall not apply) to an Indemnified Party in respect of any Losses or Expenses referred to herein, then the Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Expense or Loss in such proportion as is appropriate to reflect the relative fault of the Marathon Petroleum Indemnified Parties, on the one hand, and the Marathon Oil Indemnified Parties, on the other hand, in connection with the conduct, statements or omissions that resulted in such Expense or Loss. The relative fault of any Marathon Petroleum Indemnified Party, on the one hand, and of any Marathon Oil Indemnified Party, on the other hand, in the case of any Expense or Loss arising out of or related to information contained in the Form 10 Registration Statement, the Information Statement, any Notes Offering Memorandum, the Stock Options Registration Statement (or related prospectus forming a part thereof), any other registration statement filed by Marathon Petroleum (or related prospectus forming a part thereof) or other securities law filing shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission of a material fact relates to information supplied by the Marathon Petroleum Business or a Marathon Petroleum Indemnified Party, on the one hand, or by the Marathon Oil Business or a Marathon Oil Indemnified Party, on the other hand. Only the Designated Marathon Information shall be deemed supplied by the Marathon Oil Business or the Marathon Oil Indemnified Parties. All other information in the Form 10 Registration Statement, the Information Statement, any Notes Offering Memorandum, the Stock Options Registration Statement (or related prospectus forming a part thereof) and any other registration statement filed by Marathon Petroleum (or related prospectus forming a part thereof) shall be deemed supplied by the Marathon Petroleum Business or the Marathon Petroleum Indemnified Parties. The Parties agree that it would not be just and equitable if contribution were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above.

SECTION 11.9 Remedies Cumulative . The remedies provided in this Article XI shall be cumulative and, subject to the provisions of Article XI , shall not preclude assertion by an

44

Indemnified Party of any other rights or the seeking of any and all other remedies against any Indemnifying Party; provided that the procedures set forth in this Article XI shall be the exclusive procedures governing any indemnity action brought under this Agreement.

SECTION 11.10 Survival . All covenants and agreements of the Parties contained in this Agreement relating to indemnification shall survive the Distribution Date indefinitely, unless a specific survival or other applicable period is expressly set forth herein.

SECTION 11.11 No Special Damages. IN NO EVENT SHALL ANY PARTY BE LIABLE UNDER THIS ARTICLE XI OR OTHERWISE IN RESPECT OF THIS AGREEMENT OR ANY OPERATING AGREEMENT FOR EXEMPLARY, SPECIAL, PUNITIVE, INDIRECT, REMOTE, SPECULATIVE OR CONSEQUENTIAL DAMAGES (INCLUDING IN RESPECT OF LOST PROFITS OR REVENUES), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY (INCLUDING NEGLIGENCE), WHETHER OR NOT SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, EXCEPT TO THE EXTENT ANY SUCH PARTY INCURS SUCH DAMAGES PAYABLE TO A THIRD PARTY IN CONNECTION WITH A THIRD-PARTY CLAIM, IN WHICH EVENT SUCH DAMAGES SHALL BE RECOVERABLE.

SECTION 11.12 Ancillary Agreements . Notwithstanding anything in this Agreement to the contrary, to the extent any Operating Agreement contains any indemnification obligation or contribution obligation relating to any Marathon Oil Liability, Marathon Petroleum Liability or Transferred Asset contributed, assumed, retained, transferred, delivered, conveyed or governed pursuant to such Operating Agreement, the indemnification obligations and contribution obligations contained herein shall not apply to such Marathon Oil Liability, Marathon Petroleum Liability or Transferred Asset and instead the indemnification obligations and/or contribution obligations set forth in such Operating Agreement shall govern with regard to such Marathon Oil Liability, Marathon Petroleum Liability or Transferred Asset.

ARTICLE XII

DISPUTE RESOLUTION

SECTION 12.1 Agreement to Arbitrate . Except as otherwise specifically provided herein or in any Operating Agreement, the procedures for discussion, negotiation and arbitration set forth in this Article XII shall apply to all disputes, controversies or claims (whether sounding in contract, tort or otherwise) that may arise out of or relate to, or arise under or in connection with this Agreement or any Operating Agreement or the transactions contemplated hereby or thereby (including all actions taken in furtherance of the transactions contemplated hereby or thereby on or before the date of this Agreement or the Distribution Date), between or among any of the Marathon Oil Parties and the Marathon Petroleum Parties. Each Party hereto agrees on behalf of itself and its respective Subsidiaries that the procedures set forth in this Article XII shall be the sole and exclusive remedy in connection with any dispute, controversy or claim relating to any of the foregoing matters and irrevocably waives any right to commence any Action in or before any Governmental Authority, except as expressly provided in Section 12.7(b) and except to the extent provided under the Arbitration Act in the case of judicial review of arbitration results or awards. EACH PARTY ON BEHALF OF ITSELF AND ITS

45

RESPECTIVE SUBSIDIARIES IRREVOCABLY WAIVES ANY RIGHT TO ANY TRIAL IN A COURT THAT WOULD OTHERWISE HAVE JURISDICTION OVER ANY CLAIM, CONTROVERSY OR DISPUTE SET FORTH IN THE FIRST SENTENCE OF THIS SECTION 12.1 .

SECTION 12.2 Escalation .

(a) The Parties hereto agree to use commercially reasonable efforts to resolve expeditiously any dispute, controversy or claim between them or any of their respective Subsidiaries with respect to the matters covered hereby that may arise from time to time on a mutually acceptable negotiated basis. In furtherance of the foregoing, any Party hereto involved in a dispute, controversy or claim may deliver a notice (an “Escalation Notice”) demanding an in-person meeting involving representatives of the Parties hereto at a senior level of management of the Parties hereto (or if the Parties hereto agree, of the appropriate strategic business unit or division within each Party). A copy of any such Escalation Notice shall be given to the General Counsel, or like officer, of each Party involved in the dispute, controversy or claim (which copy shall state that it is an Escalation Notice pursuant to this Agreement). Any agenda, location or procedures for such discussions or negotiations between the Parties may be established by the Parties from time to time; provided, however , that the Parties shall use commercially reasonable efforts to meet within 30 days of the Escalation Notice.

(b) If the Parties are unable to resolve the dispute within 30 business days after the date of the Escalation Notice, any Party hereto will have the right to begin arbitration and submit an Arbitration Demand Notice in accordance with Section 12.3 .

(c) The Parties may, by mutual consent, select a mediator to aid the Parties in their discussions and negotiations. Any opinion expressed by any such mediator shall be strictly advisory and shall not be binding on the Parties, nor shall any opinion expressed by any such mediator be admissible in any arbitration proceedings. Costs of any mediation shall be borne equally by the Parties, except that each Party shall be responsible for its own expenses. Mediation is not a prerequisite to a demand for arbitration under Section 12.3 .

(d) The Parties agree that all discussions, negotiations and other information exchanged between the Parties during the foregoing proceedings will be without prejudice to the legal position of a Party in any subsequent Action.

SECTION 12.3 Procedures for Arbitration.

(a) At any time following the 30 business day period set forth in Section 12.2(b) (the “Arbitration Demand Date”), any Party involved in the dispute, controversy or claim (regardless of whether such Party delivered the Escalation Notice) may, unless the Applicable Deadline (as hereinafter defined) has occurred, make a written demand (the “Arbitration Demand Notice”) that the dispute be resolved by binding arbitration, which Arbitration Demand Notice shall be given to the Parties to the dispute, controversy or claim in the manner set forth in Section 14.9 . If any Party shall deliver an Arbitration Demand Notice to another Party, such other Party may itself deliver an Arbitration Demand Notice to such first Party with respect to any related dispute, controversy or claim with respect to which the Applicable Deadline has not passed without the

46

requirement of delivering an Escalation Notice. No Party may assert that the failure to resolve any matter during any discussions or negotiations, the course of conduct during the discussions or negotiations or the failure to agree on a mutually acceptable time, agenda, location or procedures for the meeting, in each case, as contemplated by Section 12.2 , is a prerequisite to a demand for arbitration under this Section 12.3 . If either Party delivers an Arbitration Demand Notice with respect to any dispute, controversy or claim that is the subject of any then pending arbitration proceeding or of a previously delivered Arbitration Demand Notice, all such disputes, controversies and claims shall be resolved in the arbitration proceeding for which an Arbitration Demand Notice was first delivered unless the arbitrator in his or her sole discretion determines that it is impracticable or otherwise inadvisable to do so.

(b) Except as may be expressly provided in any Operating Agreement, any Arbitration Demand Notice may be given until two years after the later of (i) the occurrence of the act or event giving rise to the underlying claim (it being understood that in the case of a Third-Party Claim, such date shall be the date of assertion of the Third-Party Claim rather than the act or event underlying the Third-Party 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 claim (as applicable and as it may in a particular case be specifically extended by the Parties in writing, the “Applicable Deadline”). Any discussions, negotiations or mediations between the Parties pursuant to this Agreement or otherwise will not toll the Applicable Deadline unless expressly agreed in writing by the Parties. Each Party agrees, on behalf of itself and its respective Subsidiaries, that, if an Arbitration Demand Notice with respect to a dispute, controversy or claim is not given prior to the expiration of the Applicable Deadline, such dispute, controversy or claim will be barred. Subject to Section 12.7(d) , upon delivery of an Arbitration Demand Notice pursuant to Section 12.3(a) prior to the Applicable Deadline, the dispute, controversy or claim shall be decided by one or more arbitrators in accordance with the rules set forth in this Article XII .

SECTION 12.4 Selection of Arbitrator.

(a) Except as otherwise set forth herein, any arbitration hereunder will be conducted in accordance with the American Arbitration Association (the “AAA”) Comprehensive Arbitration Rules and Procedures then prevailing. Unless the Parties otherwise agree, any such arbitration shall be conducted by and before a single arbitrator. Within 16 days following the delivery of any Arbitration Demand Notice hereunder, the Parties shall jointly request AAA to nominate ten candidates to act as arbitrator with respect to the dispute, by written notice to the Parties ( provided , however , that, if the Party that submitted the Arbitration Demand Notice is unable to obtain the cooperation of the other Party to make such joint request, the Party that submitted such notice may make the request on behalf of both parties). Within 10 days following their receipt of such notice from AAA, the Parties shall concurrently exchange their respective rankings of the ten candidates and shall seek to select the arbitrator by mutual agreement. If the Parties do not reach agreement on the selection of the arbitrator within 20 days following their receipt of the notice from AAA providing the ten candidates (as evidenced by their joint notice of selection to AAA), the selection shall be made by AAA, which selection will take into account the Parties’ rankings of the candidates referred to in the immediately preceding sentence, if such rankings are provided to AAA. If the Parties determine, by mutual written agreement, to utilize an arbitration panel, consisting of two or more arbitrators, in connection

47

with any dispute, each such arbitrator shall be selected pursuant to the procedures set forth in this Section 12.4(a) (and, in that event, any references to the “arbitrator” in this Article XII shall be deemed to refer such arbitration panel or each such arbitrator or any such arbitrator, as the context indicates or requires). Any arbitrator selected pursuant to this Section 12.4(a) shall be neutral and disinterested with respect to each of the Parties and the matter and shall be reasonably competent in the applicable subject matter.

(b) The arbitrator selected pursuant to Section 12.4(a) will set a time for the hearing of the matter, which will commence no later than 180 days after the selection of the arbitrator pursuant to Section 12.4(a) . The arbitrator may extend such period at his or her discretion pursuant to a reasoned request from either Party or on his or her own initiative if it is necessary to do so. The arbitrator shall use his or her best efforts to reach a final decision and render the same in writing to the Parties not later than 60 days after the last hearing date, unless otherwise agreed by the Parties in writing. Failure of the arbitrator to do so, however, shall not be a basis for challenging the decision.

SECTION 12.5 Hearings . The arbitrator shall actively manage the arbitration with a view to achieving a just, speedy and cost-effective resolution of the dispute, claim or controversy. The arbitrator shall determine whether an oral hearing is required or whether the dispute should be submitted for a judgment or decision based on written submissions, verified witness statements and other written evidence. The arbitrator may, in his or her sole discretion, set time and other limits on the presentation of each Party’s case, its memoranda or other submissions, and refuse to receive any proffered evidence that the arbitrator finds to be cumulative, unnecessary, irrelevant or of low probative nature. The decision of the arbitrator will be final and binding on the Parties, and judgment thereon may be had and will be enforceable in any court having jurisdiction over the Parties. Arbitration awards will bear interest from the date of the award at an annual rate of the Prime Rate plus 2%. To the extent that the provisions of this Agreement and the prevailing rules of the AAA conflict, the provisions of this Agreement shall govern.

SECTION 12.6 Discovery and Certain Other Matters.

(a) Discovery procedures available in litigation before the courts shall not apply in any arbitration proceedings hereunder. Any Party involved in the applicable dispute, controversy or claim may request limited document production from the other Party or Parties of specific and expressly relevant documents, with the reasonable expenses of the producing Party or Parties incurred in such production paid by the requesting Party. Any such discovery shall be conducted expeditiously and shall not cause the hearing provided for in Section 12.5 to be adjourned except upon consent of both Parties or upon a showing of cause demonstrating that such adjournment is necessary to permit discovery essential to a Party to the proceeding. Depositions, interrogatories or other forms of discovery (other than the document production set forth above) shall not occur except by consent of all Parties involved in the applicable dispute, controversy or claim. Disputes concerning the scope of document production and enforcement of the document production requests will be referred to the arbitrator for resolution. All discovery requests will be subject to the Parties’ rights to claim any applicable privilege. The arbitrator will adopt procedures to protect the proprietary rights of the Parties and to maintain the confidential treatment of the arbitration proceedings (except as may be required by applicable law). Subject

48

to the foregoing, the arbitrator shall have the power to issue subpoenas to compel the production of documents relevant to the dispute, controversy or claim.

(b) The arbitrator shall have full power and authority to determine issues of arbitrability but shall otherwise be limited to interpreting or construing the applicable provisions of this Agreement or any Operating Agreement, and will have no authority or power to limit, expand, alter, amend, modify, revoke or suspend any condition or provision of this Agreement or any Operating Agreement; it being understood, however, that the arbitrator will have full authority to implement the provisions of this Agreement or any Operating Agreement and to fashion appropriate remedies for breaches of this Agreement (including interim or permanent injunctive relief); provided, however , that the arbitrator shall not have (i) any authority in excess of the authority a court having jurisdiction over the Parties and the controversy or dispute would have absent these arbitration provisions or (ii) any right or power to award exemplary, punitive, special, indirect, consequential, remote or speculative damages (including in respect of lost profits or revenues) or treble damages (provided that this clause (ii) shall not limit the award of any such damages to the extent they are included in any Liabilities to third parties as to which the provisions of this Article XII are applicable). It is the intention of the Parties that in rendering a decision the arbitrator gives effect to the applicable provisions of this Agreement and the Operating Agreements and follow applicable law (it being understood and agreed that this sentence shall not give rise to a right of judicial review of the award of the arbitrator).

(c) If a Party fails or refuses to appear at and participate in an arbitration hearing after due notice, the arbitrator may hear and determine the controversy upon evidence produced by the appearing Party. Any decision rendered under such circumstances shall be as valid and enforceable as if the Parties had appeared and participated fully at all stages.

(d) The fees of the arbitrator and all other arbitration costs shall be borne equally by each Party involved in the matter, except that each Party shall be responsible for its own attorney’s fees and other costs and expenses, including the costs of witnesses selected by such Party.

SECTION 12.7 Certain Additional Matters.

(a) Any arbitration award shall be an award with a holding in favor of or against a Party and shall include findings as to facts, issues or conclusions of law (including with respect to any matters relating to the validity or infringement of patents or patent applications) and shall include a statement of the reasoning on which the award rests. The award must also be in adequate form so that a judgment of a court may be entered thereupon. Judgment upon any arbitration award hereunder may be entered in any court having jurisdiction thereof. Any award shall not be vacated or appealed except on the bases of (i) the award being procured by fraud or corruption, (ii) the arbitrator being partial or corrupt, (iii) the arbitrator wrongfully refusing to postpone a hearing or hear evidence, or (iv) the arbitrator exceeding the scope of the power granted to the arbitrator in this Agreement.

(b) Regardless of whether an Escalation Notice has been delivered, prior to the time at which the arbitrator is appointed pursuant to Section 12.4 , either Party may seek one or more temporary restraining orders in a court of competent jurisdiction if necessary in order to preserve

49

and protect the status quo. Neither the request for, nor the grant or denial of, any such temporary restraining order shall be deemed a waiver of the obligation to arbitrate as set forth herein, and the arbitrator may order the Parties to petition the court to dissolve, continue or modify any such order. Any such temporary restraining order shall remain in effect until the first to occur of the expiration of the order in accordance with its terms or the dissolution thereof.

(c) Except as required by law, the Parties shall hold, and shall cause their respective officers, directors, employees, agents and other representatives to hold, the existence, content and result of mediation or arbitration in confidence in accordance with the provisions of Article XIII and except as may be required in order to enforce any award. Each of the Parties shall request that the arbitrator comply with such confidentiality requirement.

(d) If at any time the arbitrator shall fail to serve as such for any reason, the Parties shall select a new arbitrator who shall be disinterested as to the Parties and the matter in accordance with the procedure set forth herein for the selection of the initial arbitrator. The extent, if any, to which testimony previously given shall be repeated or as to which the replacement arbitrator elects to rely on the stenographic record (if there is one) of such testimony shall be determined by the arbitrator.

SECTION 12.8 Continuity of Service and Performance . Unless otherwise agreed in writing, the Parties will continue to provide service and honor all other commitments under this Agreement and each Operating Agreement during the course of dispute resolution pursuant to the provisions of this Article XII with respect to all matters not subject to such dispute, controversy or claim to the extent such Party is obligated to do so pursuant to the underlying agreement.

SECTION 12.9 Law Governing Arbitration Procedures . The interpretation of the provisions of this Article XII , only insofar as they relate to the agreement to arbitrate and any procedures pursuant thereto, shall be governed by the Arbitration Act and other applicable U.S. federal law. In all other respects, the interpretation of this Agreement shall be governed as set forth in Section 14.2 .

SECTION 12.10 Choice of Forum . Any arbitration proceedings hereunder shall take place in Atlanta, Georgia, unless another location is otherwise agreed to in writing by the Parties.

The access to information being granted pursuant to Section 13.1 , the agreement to provide witnesses and individuals pursuant to Section 13.6 and the transfer of Privileged Information to Marathon Petroleum pursuant to this Agreement shall not be deemed a waiver of any Privilege that has been or may be asserted under this Section 13.9 or otherwise.
