 (v) Except as required by applicable law or as a result of a Final
Determination, neither Parent nor SpinCo shall (nor shall cause or permit any other members of the Parent Group or SpinCo Group, respectively, to) take any position that is either inconsistent with the treatment of the Spin-Off-Related Transactions
as having Tax-Free Status (or analogous status under state, local or foreign law) or with respect to a specific item of income, deduction, gain, loss or credit on an Income Tax Return or Other Tax Return, treat such specific item in a manner which

Tax Return or Other Tax Return).

Return with respect to which Income Taxes pursuant to this Section 3(b)(i) are due, or (y) five Business Days after Parent provides written notice setting forth the computation of such Income Taxes, SpinCo shall pay to Parent any such
Income Taxes in excess of the estimated payment previously paid by SpinCo or, if the estimated Income Taxes paid by SpinCo exceed the amount otherwise payable, Parent shall refund such excess to SpinCo.

 (ii) Other Income Tax Returns that are Combined Returns for
Pre-Distribution Taxable Periods. Parent shall prepare and file or cause to be prepared and filed all Income Tax Returns that are Combined Returns (other than the U.S. consolidated federal Income Tax Returns described in Section 3(b)(i)
above) for all Pre-Distribution Taxable Periods and shall pay all Income Taxes due with respect to such Income Tax Returns. In consideration of Parent’s payment of such Income Taxes (as well as Income Taxes payable with respect to any Parent
Separate Returns that are attributable to income, gain or guaranteed payments of MPC LP) for the taxable year ending December 31, 2011, with respect to each such Combined Return and each Parent Separate Return that includes an allocation of
income, gain or guaranteed payments with respect to MPC LP, SpinCo shall pay to Parent an amount equal to the product of (i) the net amount of any taxable income of SpinCo (and each other member of the SpinCo Group, including MPC LP) that is
included in such Tax Return for the taxable year ending December 31, 2011, and (ii) the product of (A) the highest income tax corporate marginal rate in effect in the applicable Taxing Jurisdiction for such year, and
(B) sixty-five percent (0.65). Prior to the Distribution Date, SpinCo shall pay to Parent an estimate of the Income Taxes payable pursuant to the preceding sentence. Upon the later of (x) 10 Business Days after Parent files the applicable
Income Tax Return with respect to which such Income Taxes are due, or (y) five Business Days after Parent provides written notice setting forth the computation of such Income Taxes, SpinCo shall pay to Parent any such Income Taxes in excess of
the estimated payment previously paid by SpinCo or, if the estimated Income Taxes paid by SpinCo exceed the amount otherwise payable, Parent shall refund such excess to SpinCo. 

(iii) MPC LP Tax Returns. Parent (on behalf of MPC LP) shall prepare and file (or cause to be prepared and filed)
all U.S. returns of partnership income on IRS Form 1065 and any similar state, local or foreign Tax Returns of MPC LP for taxable periods ending on or before December 31, 2010. SpinCo (on behalf of MPC LP) shall prepare and file (or cause to be
prepared and filed) all such Tax Returns of MPC LP with respect to taxable periods beginning on or after January 1, 2011, including any Straddle Periods. In the case of any Tax Return described in the preceding sentence for which items of
income, gain, deduction, loss, credit or guaranteed payments of MPC LP are allocable to any member of the Parent Group, at least 30 days prior to the due date of such Tax Return, SpinCo shall submit a copy of such Tax Return to Parent. No later than
15 days after receipt of the Tax Return, Parent shall provide written notice to SpinCo of any proposed changes to such Tax Return, which comments shall be considered in good faith. MPC LP shall be responsible for all Income Taxes or Other Taxes that
are imposed by any Tax Authority on MPC LP (as opposed to Taxes that are payable by MPC LP’s owners with 

  
 14 

 
respect to their allocable shares of MPC LP’s income) for all taxable years. 
 (iv) Payroll Taxes. Parent and SpinCo each shall pay or cause to be paid any Payroll Taxes with respect to Parent Employees or SpinCo Employees, respectively, and shall be responsible for filing
any Tax Returns due with respect to such Payroll Taxes. 
 (v) Parent Separate Returns. Parent shall
prepare and file or cause to be prepared and filed all Parent Separate Returns. Except as provided in Sections 3(b)(ii) and 3(c)(i), Parent shall pay, or cause to be paid, and shall be responsible for, any and all Income Taxes or Other Taxes due or
required to be paid with respect to any Parent Separate Return. 
 (vi) SpinCo Separate Returns. Except as
provided in Section 3(b)(iii), SpinCo shall prepare and file or cause to be prepared and filed all SpinCo Separate Returns and shall be responsible for any and all Income Taxes or Other Taxes due or required to be paid with respect to any
SpinCo Separate Return for both Pre-Distribution Taxable Periods and Post-Distribution Taxable Periods. 
 (vii)
Transfer Taxes. SpinCo shall be responsible for, and shall indemnify each member of the Parent Group against, all transfer, documentary, sales, use, registration and similar Taxes and related fees incurred as a result of the Spin-Offs
(including the MOC Contribution and the MRO Contribution), and shall timely prepare and file all Other Tax Returns as may be required in connection with the payment of such Taxes. 

(viii) Amended Returns. (A) Except as provided in Section 3(b)(viii)(D), SpinCo (and not any member of
the Parent Group) shall be entitled to amend any SpinCo Separate Returns, (B) Parent (and not any member of the SpinCo Group) shall be entitled to amend any Parent Separate Returns, (C) Parent (and not any member of the SpinCo Group) shall
be entitled to file amended Combined Returns for any Pre-Distribution Taxable Period, and (D) Parent (and not any member of the SpinCo Group) shall be entitled to cause MPC LP to file an amended return for any Pre-Distribution Taxable Period.
In the event that an amended return described in Section 3(b)(viii)(B), (C) or (D) results in a Refund of Taxes to any member of the Parent Group or the SpinCo Group, the party entitled to such Refund shall be the party that would be
entitled to such Refund under Section 3(c)(ii) if such Refund had been attributable to a Final Determination, and if such amended return results in the payment of additional Taxes, such Taxes shall be the responsibility of the party that would
be responsible for such Taxes under Section 3(c)(i) if 

  
 15 

 
such Taxes had been attributable to a Parent Adjustment or a SpinCo Adjustment, as the case may be. 
 (ix) Timing of Payments. Except as otherwise specifically set forth in this Agreement, all payments required to be made by one Person to another Person pursuant to this Section 3 shall be made
no later than five days prior to the date such Taxes are due to the relevant Tax Authority or, in the case of any amended Tax Return, within five days after any Taxes attributable to such Tax Return are Actually Realized. 

(c) Tax Adjustments due to a Final Determination and Refunds.  

(i) Pre-Distribution Taxable Periods. Except as provided in Sections 3(c)(iii) and (iv), Parent shall pay or cause
to be paid all Taxes attributable to Parent Adjustments for all Pre-Distribution Taxable Periods. Except as provided in Sections 3(c)(iii) and (iv), SpinCo shall pay or cause to be paid all Taxes attributable to SpinCo Adjustments for all
Pre-Distribution Taxable Periods. For the avoidance of doubt, SpinCo shall be responsible for any increase in Taxes of any member of the Parent Group for a Pre-Distribution Taxable Period to the extent such increase is attributable to any adjustment
to an item of income, gain, deduction, loss or credit of MPC LP. If a SpinCo Adjustment increases the taxable income on a Tax Return for which the Parent Group is responsible for the payment of Taxes, or if a Parent Adjustment increases the taxable
income on a Tax Return for which the SpinCo Group is responsible for the payment of Taxes, the increase in Taxes (other than any penalties and interest, which shall be determined on an as-assessed basis) attributable to such adjustment shall be
computed in accordance with the formulas in Sections 3(b)(i) and (ii); thus, for example, if a SpinCo Adjustment increases the taxable income reported on the Parent Consolidated Group’s U.S. federal Income Tax Return for the taxable year ending
December 31, 2010, the Taxes attributable to such adjustment shall be computed by multiplying the increase in the taxable income times the highest federal income tax corporate marginal rate in effect for 2010 (and adding to such amount any
penalties and interest actually assessed). 
 (ii) Refunds. (A) Except as provided in
Section 3(c)(ii)(B), Parent shall be entitled to all Refunds of Taxes received by any member of the SpinCo Group or the Parent Group with respect to any Pre-Distribution Taxable Period. (B) SpinCo shall be entitled to Refunds of Taxes for
Pre-Distribution Taxable Periods to the extent such Refunds are attributable to SpinCo Adjustments. For the avoidance of doubt, SpinCo shall be entitled to Refunds of Taxes for Pre-Distribution Taxable Periods to the extent such Refunds are
attributable to an adjustment to an item of income, gain, deduction, loss or credit of MPC LP. A party receiving a Refund to which another party is entitled pursuant to this Section 3(c)(ii) shall pay the

  
 16 

 
amount to which such other party is entitled within fifteen Business Days after such Refund is Actually Realized. 

(iii) Payroll Taxes. In the event of any Final Determination that increases the Payroll Taxes payable by any member
of the Parent Group or the SpinCo Group for any Pre-Distribution Taxable Period, such Payroll Taxes shall be the responsibility of (A) Parent if such Payroll Taxes are with respect to a Parent Employee, or (B) SpinCo if such Payroll Taxes
are with respect to a SpinCo Employee. 
 (iv) Ashland Adjustments. Notwithstanding any other provision of
this Agreement, SpinCo shall pay or cause to be paid (to Parent or to the Tax Authority, as applicable), any Income Taxes or any Other Taxes payable by any member of the Parent Group to the extent such Taxes are attributable to Ashland Adjustments.

 (v) Certain Partnership Items. For avoidance of doubt, notwithstanding any other provision of this
Agreement, Parent shall not be responsible (directly, by reason of indemnification or otherwise) for any Taxes payable by any member of the SpinCo Group for any Post-Distribution Taxable Period that are attributable to a termination of MPC LP
pursuant to Section 708(b). 
 4. Indemnification for Income Taxes and Other Taxes. 

(a) Indemnification by Parent. From and after the Distribution Date, except as provided in Section 3, Parent and each other
member of the Parent Group shall jointly and severally indemnify, defend and hold harmless SpinCo and each other member of the SpinCo Group and each of their respective Representatives from and against (i) all Income Tax Liabilities and Other
Tax Liabilities that Parent or any other member of the Parent Group is responsible for pursuant to Section 3 and (ii) all Income Taxes, Other Taxes, Spin-Off Tax Liabilities and other Tax-Related Losses incurred by any member of the Parent
Group or SpinCo Group that are attributable to, are caused by, or result from, one or more of the following: (A) any breach by a member of the Parent Group of a covenant or representation related to the Parent Group or the Parent Business
hereunder or made in connection with the Tax Opinion Documents; (B) any action or omission by a member of the Parent Group after the Distribution Date (including any act or omission that is in furtherance of, connected to, or part of a plan or
series of related transactions (within the meaning of Section 355(e) of the Code) occurring on or prior to the Distribution Date) including a cessation, transfer to Affiliates or disposition of a Parent Business; (C) any acquisition of any
stock or assets of a member of the Parent Group by one or more other persons (other than a member of the SpinCo Group) prior to or following the Distribution Date; or (D) any issuance of Equity Securities by a member of the Parent Group;
provided, however, that neither Parent nor any other member of the Parent Group shall have any obligation to indemnify, defend or hold harmless any Person pursuant to this Section 4(a) to the extent that such indemnification obligation
is otherwise attributable to any breach by SpinCo or 

  
 17 

 
any other member of the SpinCo Group of any of SpinCo’s representations or covenants hereunder (including any representations made in connection with the Tax Opinion). 

(b) Indemnification by SpinCo. From and after the Distribution Date, SpinCo and each other member of the SpinCo Group shall
jointly and severally indemnify, defend and hold harmless Parent and each other member of the Parent Group and each of their respective Representatives from and against (i) all SpinCo Tax Liabilities, Income Tax Liabilities, Other Tax
Liabilities, Spin-Off Tax Liabilities and other Tax-Related Losses that SpinCo or any other member of the SpinCo Group is responsible for under Section 3 or Section 5 (including any Income Tax Liabilities, Other Tax Liabilities, Spin-Off
Tax Liabilities or other Tax-Related Losses arising with respect to a Permitted Transaction for which SpinCo is liable pursuant to Section 5), and (ii) all Income Taxes, Other Taxes, Spin-Off Tax Liabilities and other Tax-Related Losses
incurred by any member of the Parent Group or SpinCo Group that are attributable to, are caused by, or result from, one or more of the following: (A) any breach by a member of the SpinCo Group of a covenant or representation related to the
SpinCo Group or the SpinCo Business hereunder or made in connection with the Tax Opinion Documents; (B) any action or omission by a member of the SpinCo Group after the Distribution Date (including any act or omission that is in furtherance of,
connected to, or part of a plan or series of related transactions (within the meaning of Section 355(e) of the Code) occurring on or prior to the Distribution Date) including a cessation, transfer to Affiliates or disposition of a SpinCo
Business; (C) any acquisition of any stock or assets of a member of the SpinCo Group by one or more other persons (other than a member of the Parent Group) following the Distribution Date; or (D) any issuance of Equity Securities by a
member of the SpinCo Group; provided, however, that neither SpinCo nor any other member of the SpinCo Group shall have any obligation to indemnify, defend or hold harmless any Person pursuant to this Section 4(b) to the extent that such
indemnification obligation is otherwise attributable to any breach by Parent or any other member of the Parent Group of any of Parent’s representations or covenants hereunder (including any representations made in connection with the Tax
Opinion). 
 (c) Timing of Indemnification Payments. Any payment with respect to any indemnification obligation pursuant
to this Section 4 shall be made by the Indemnifying Party promptly, but, in any event, no later than: 
 (i)
in the case of an indemnification obligation with respect to any SpinCo Tax Liabilities, Spin-Off Tax Liabilities, Income Tax Liabilities or Other Tax Liabilities, the later of (A) five Business Days after the Indemnified Party notifies the
Indemnifying Party and (B) five Business Days prior to the date the Indemnified Party is required to make a payment of taxes, interest, or penalties to the applicable Tax Authority (including a payment with respect to an assessment of a tax
deficiency by any Taxing Jurisdiction or a payment made in settlement of an asserted tax deficiency) or realizes a reduced Refund; and 
 (ii) in the case of any payment or indemnification of any Losses not described in Section 4(c)(i) (including, but not limited to, any Losses described in clause (b) or (c) of the definition
of Tax-Related 

  
 18 

 
Losses, attorneys’ fees and expenses and other indemnifiable Losses), the later of (A) five Business Days after the Indemnified Party notifies the Indemnifying Party and (B) five
Business Days prior to the date the Indemnified Party makes a payment thereof. 
 (d) Tax Benefits. If the
indemnification provided by Parent under Section 4(a) results in (i) increased deductions, losses, or credits, or (ii) decreases in income, gains or recapture of Tax credits (“Tax Benefits”) to SpinCo or any other member of
the SpinCo Group, which would not, but for the indemnification obligation (or the adjustment giving rise to such indemnification obligation), be allowable, then SpinCo shall pay Parent the amount by which such Tax Benefit actually reduces, in cash,
the amount of Tax that SpinCo or any other member of the SpinCo Group would have been required to pay and bear (or increases, in cash, the amount of a Refund to which SpinCo or any other member of the SpinCo Group would have been entitled) but for
such indemnification obligation (or adjustment giving rise to such indemnification obligation). SpinCo shall pay Parent for such Tax Benefit no later than five Business Days after such Tax Benefit is Actually Realized. If the indemnification
provided by SpinCo under Section 4(b) results in Tax Benefits to Parent or any other member of the Parent Group, which would not, but for the indemnification obligation (or the adjustment giving rise to such indemnification obligation), be
allowable, then Parent shall pay SpinCo the amount by which such Tax Benefit actually reduces, in cash, the amount of Tax that Parent or any other member of the Parent Group would have been required to pay and bear (or increases, in cash, the amount
of a Refund to which Parent or any other member of the Parent Group would have been entitled) but for such indemnification obligation (or adjustment giving rise to such indemnification obligation). Parent shall pay SpinCo for such Tax Benefit no
later than five Business Days after such Tax Benefit is Actually Realized. 
 5. Spin-Off Related Matters.

 (a) Representations. 
 (i) Tax Opinion Documents. SpinCo hereby represents and warrants that (A) it has examined the Tax Opinion Documents (including the representations to the extent that they relate to the plans,
proposals, intentions, and policies of SpinCo, its Subsidiaries, the SpinCo Business, or the SpinCo Group) and (B) to the extent in reference to SpinCo, its Subsidiaries, the SpinCo Business, or the SpinCo Group, the facts presented and the
representations made therein are true, correct and complete. 
 (ii) Tax-Free Status. SpinCo hereby
represents and warrants that neither SpinCo nor any other member of the SpinCo Group has a plan or intention of taking any action, or failing to take any action, or knows of any circumstance, that could reasonably be expected to (A) cause any
of the Spin-Off-Related Transactions not to have Tax-Free Status or (B) cause any representation or factual statement made in this Agreement, the Separation and Distribution Agreement or the Tax Opinion Documents to

  
 19 

 
be untrue in a manner that would have an adverse effect on the Tax-Free Status of any of the Spin-Off-Related Transactions. 

(iii) Plan or Series of Related Transactions. SpinCo hereby represents and warrants that, to the best knowledge of
SpinCo, after due inquiry, none of the Spin-Off-Related Transactions are part of a plan (or series of related transactions) pursuant to which a Person will acquire stock representing a Fifty-Percent or Greater Interest in SpinCo or any successor to
SpinCo. 
 (b) Covenants. 
 (i) Actions Consistent with Representations and Covenants. Neither Parent nor SpinCo shall take any action or permit any other member of the Parent Group or the SpinCo Group, respectively, to take
any action, or shall fail to take any action or permit any other member of the Parent Group or the SpinCo Group, respectively, to fail to take any action, where such action or failure to act would be inconsistent with or cause to be untrue any
material information, covenant or representation in this Agreement, the Separation and Distribution Agreement or the Tax Opinion Documents. 
 (ii) Preservation of Tax-Free Status; SpinCo Business. SpinCo shall not (A) take any action (including any cessation, transfer or disposition of all or any portion of any SpinCo Business,
payment of extraordinary dividends, acquisitions or issuances of stock or entering into any agreement, understanding, arrangement or substantial negotiations regarding any such actions) or permit any other member of the SpinCo Group to take any such
action, or fail to take any such action or permit any other member of the SpinCo Group to fail to take any such action, in each case, unless such action or failure to act would not cause any of the Spin-Off-Related Transactions not to have Tax-Free
Status or could not require Parent or SpinCo to reflect a liability or reserve with respect to any of the Spin-Off-Related Transactions in its financial statements, and (B) until the first day after the Restriction Period, engage in any
transaction (including any cessation, transfer or disposition of all or any portion of any SpinCo Business) that would result in SpinCo or its “separate affiliated group” (within the meaning of Section 355(b) of the Code) ceasing to
be engaged in any SpinCo Business for purposes of Section 355(b). 
 (iii) Sales, Issuances and
Redemptions of Equity Securities. Until the first day after the Restriction Period, none of SpinCo or any other member of the SpinCo Group shall, or shall agree to, sell or otherwise issue to any Person, or redeem or otherwise acquire from any
Person, any Equity Securities of SpinCo or any other member of the SpinCo Group; provided, however, that SpinCo may issue such Equity Securities to the 

  
 20 

 
extent such issuances satisfy Safe Harbor VIII (relating to acquisitions in connection with a person’s performance of services) or Safe Harbor IX (relating to acquisitions by a retirement
plan of an employer) of Treasury Regulation Section 1.355-7(d). 
 (iv) Tender Offer; Other Business
Transactions. Until the first day after the Restriction Period, none of SpinCo or any other member of the SpinCo Group shall (A) solicit any Person to make a tender offer for, or otherwise acquire or sell, the Equity Securities of SpinCo,
(B) participate in or support any unsolicited tender offer for, or other acquisition, issuance or disposition of, the Equity Securities of SpinCo or (C) approve or otherwise permit any proposed business combination or any transaction
which, in the case of clauses (A) or (B), individually or in the aggregate, together with any transaction occurring within the four-year period beginning on the date which is two years before the Distribution Date and any other transaction
which is part of a plan or series of related transactions (within the meaning of Section 355(e) of the Code) that includes the Spin-Off, could result in one or more Persons acquiring (except for acquisitions that otherwise satisfy Safe Harbor
VIII (relating to acquisitions in connection with a person’s performance of services) or Safe Harbor IX (relating to acquisitions by a retirement plan of an employer) of Treasury Regulation Section 1.355-7(d)) directly or indirectly stock
representing a 40% or greater interest, by vote or value, in SpinCo (or any successor thereto). 
 (v)
Dispositions of Assets. Until the first day after the Restriction Period, none of SpinCo or any other member of the SpinCo Group shall sell, transfer or dispose, or agree to sell, transfer or dispose, of more than 50 percent of the gross
assets of any SpinCo Business (such percentages to be measured by fair market values on the Distribution Date) or transfer any assets of the SpinCo Group in a transaction described in Section 351 of the Code (other than a transfer to a
corporation that is a member of SpinCo’s “separate affiliated group” within the meaning of Section 355(b) of the Code). The foregoing sentence shall not apply to sales, transfers, or dispositions of inventory in the ordinary
course of business. 
 (vi) Liquidations, Mergers, Reorganizations. Until the first day after the
Restriction Period, neither SpinCo nor any of its Subsidiaries shall, or shall agree to, voluntarily dissolve or liquidate or engage in any transaction involving a merger, consolidation or other reorganization; provided, however, that mergers
of direct or indirect wholly-owned Subsidiaries of SpinCo solely with and into SpinCo or with other direct or indirect wholly-owned Subsidiaries of SpinCo, and liquidations of SpinCo’s Subsidiaries are not subject to this Section 5(b)(vi)
to the extent 

  
 21 

 
not inconsistent with the Tax-Free Status of the Spin-Off-Related Transactions. 
 (c) Permitted Transactions. Notwithstanding the restrictions otherwise imposed by Sections 5(b)(iii) through 5(b)(vi), during the Restriction Period, SpinCo may (i) issue, sell, redeem or
otherwise acquire (or cause another member of the SpinCo Group to issue, sell, redeem or otherwise acquire) Equity Securities of SpinCo or any other member of the SpinCo Group in a transaction that would otherwise breach the covenant set forth in
Section 5(b)(iii), (ii) approve, participate in, support or otherwise permit a proposed business combination or transaction that would otherwise breach the covenant set forth in Section 5(b)(iv), (iii) sell or otherwise dispose
of the assets of SpinCo or any other member of the SpinCo Group in a transaction that would otherwise breach the covenant set forth in Section 5(b)(v) or (iv) merge SpinCo or any other member of the SpinCo Group with another entity without
regard to which party is the surviving entity in a transaction that would otherwise breach the covenant set forth in Section 5(b)(vi), in each case, if and only if such transaction would not violate Section 5(b)(i) or Section 5(b)(ii)
and prior to entering into any agreement contemplating a transaction described in clauses (i), (ii), (iii) or (iv) of this Section 5(c), and prior to consummating any such transaction: (X) SpinCo shall provide Parent with
an Unqualified Tax Opinion in form and substance satisfactory to Parent in its sole and absolute discretion, (Y) SpinCo shall request that Parent obtain a Private Letter Ruling to the effect that such transaction will not affect the Tax-Free
Status of any of the Spin-Off-Related Transactions and Parent shall have received such a Private Letter Ruling, in form and substance satisfactory to Parent in its sole and absolute discretion, exercised in good faith, or (Z) Parent in its sole
and absolute discretion shall have waived in writing the requirement to obtain such Unqualified Tax Opinion or Private Letter Ruling. 
 (d) Liability of SpinCo for Undertaking Certain Actions. Notwithstanding anything in this Agreement to the contrary, SpinCo and each other member of the SpinCo Group shall be responsible for any
and all Tax-Related Losses that are attributable to, or result from: 
 (i) any act or failure to act by SpinCo
or any other member of the SpinCo Group, which act or failure to act breaches any of the covenants described in Section 5(b)(i) through 5(b)(vi) of this Agreement (without regard to the exceptions or provisos set forth in such provisions),
expressly including, for this purpose, any Permitted Transaction and any act or failure to act that breaches Section 5(b)(i) or 5(b)(ii), regardless of whether such act or failure to act is permitted by Section 5(b)(iii) through 5(b)(vi);

 (ii) any acquisition of Equity Securities of SpinCo or any other member of the SpinCo Group by any Person or
Persons (including as a result of an issuance of SpinCo Equity Securities or a merger of another entity with and into SpinCo or any other member of the SpinCo Group) or any acquisition of assets of SpinCo or any other member of the SpinCo Group
(including as a result of a merger) by any Person or Persons; and 

  
 22 

 (iii) Tax Counsel withdrawing all or any portion of the Tax Opinion or any
Tax Authority withdrawing all or any portion of a Private Letter Ruling issued to Parent in connection with the Spin-Off-Related Transactions because of a breach by SpinCo or any other member of the SpinCo Group of a representation made in this
Agreement (or made in connection with the Tax Opinion or any Private Letter Ruling). 
 (e) Cooperation. 

(i) Parent shall reasonably cooperate with SpinCo in connection with any request by SpinCo for an Unqualified Tax Opinion
pursuant to Section 5(c). 
 (ii) Until the first day after the Restriction Period, SpinCo will provide
adequate advance notice to Parent in accordance with the terms of Section 5(e)(iii) of any action described in Sections 5(b)(i) through 5(b)(vi) within a period of time sufficient to enable Parent to seek injunctive relief as contemplated by
Section 5(f). 
 (iii) Each notice required by Section 5(e)(ii) shall set forth the terms and
conditions of any such proposed transaction, including (A) the nature of any related action proposed to be taken by the board of directors of SpinCo, (B) the approximate number of Equity Securities (and their voting and economic rights) of
SpinCo or any other member of the SpinCo Group (if any) proposed to be sold or otherwise issued, (C) the approximate value of SpinCo’s assets (or assets of any other member of the SpinCo Group) proposed to be transferred, and (D) the
proposed timetable for such transaction, all with sufficient particularity to enable Parent to seek injunctive relief pursuant to Section 5(f). Promptly, but in any event within 30 days after Parent receives such written notice from SpinCo,
Parent shall notify SpinCo in writing of Parent’s decision to seek such injunctive relief. 
 (f) Enforcement. The
parties hereto acknowledge that irreparable harm would occur in the event that any of the provisions of this Section 5 were not performed in accordance with their specific terms or were otherwise breached. The parties hereto agree that, in
order to preserve the Tax-Free Status of the Spin-Off-Related Transactions, injunctive relief is appropriate to prevent any violation of the foregoing covenants; provided, however, that injunctive relief shall not be the exclusive legal or
equitable remedy for any such violation. 
 6. Tax Contests. 

(a) Notification. Each of Parent and SpinCo shall notify the other party in writing of any demand, claim or notice of the
commencement of an audit received by such party from any Tax Authority or other Person with respect to any Income Taxes or Other Taxes of 

  
 23 

 
Parent or any other member of the Parent Group, or SpinCo or any other member of the SpinCo Group, respectively, for which a member of the SpinCo Group or the Parent Group, respectively, may be
responsible pursuant to this Agreement within ten (10) Business Days of receipt; provided, however, that in the case of any demand, claim or notice of the commencement of an audit that is reasonably expected to give rise to a
Distribution-Related Proceeding, regardless of whether SpinCo or Parent may be responsible for any resulting Taxes, Parent or SpinCo, as the case may be, shall provide written notice to the other party no later than ten (10) Business Days after
Parent or SpinCo receives any written notice of such a demand, claim or notice of commencement of an audit from the IRS or other Tax Authority. Each of Parent and SpinCo shall include with such notice a true, correct and complete copy of any written
communication, and an accurate and complete written summary of any oral communication, received by Parent or any other member of the Parent Group, or SpinCo or any other member of the SpinCo Group, respectively. The failure of Parent or SpinCo
timely to provide such notice in accordance with the first sentence of this Section 6(a) shall not relieve SpinCo or Parent, respectively, of any obligation to pay such Income Tax Liability or Other Tax Liability or indemnify Parent and the
other members of the Parent Group, or SpinCo and the other members of the SpinCo Group, respectively, and their respective Representatives therefor, except to the extent that the failure timely to provide such notice actually prejudices the ability
of SpinCo or Parent to contest such Income Tax Liability or Other Tax Liability or increases the amount of such Income Tax Liability or Other Tax Liability. 
 (b) Representation with Respect to Tax Disputes. Parent (or such other member of the Parent Group as Parent may designate) shall have the sole right to represent the interests of the members of the
Parent Group and the members of the SpinCo Group and to employ counsel of its choice in any Proceeding relating to (i) any U.S. consolidated federal Income Tax Returns of the Parent Consolidated Group, (ii) any other Combined Returns,
(iii) any Parent Separate Returns, and (iv) any Tax Returns of MPC LP for any Pre-Distribution Taxable Period. Parent may affirmatively elect, in writing and at its sole and absolute discretion, not to assert control of a Proceeding
described in clauses (ii) or (iv) of the immediately preceding sentence, in which case SpinCo shall have the right to control such Proceeding and Parent shall have the right to participate therein at its own cost; provided, however,
that SpinCo shall not have the right to settle any such Proceeding without the prior written consent of Parent (which shall not be unreasonably withheld). Parent shall bear all expenses relating to any Proceeding referred to in the first sentence of
this Section 6(b), except that, with respect to a Proceeding relating to any Combined Return for any Pre-Distribution Taxable Period, expenses shall be borne by Parent and SpinCo to the extent such expenses are attributable to Parent
Adjustments or SpinCo Adjustments, respectively; provided, however, that to the extent such expenses cannot reasonably be attributed to Parent Adjustments or SpinCo Adjustments, such expenses shall be borne equally by Parent and SpinCo.
Except as set forth in the first sentence of this Section 6(b), SpinCo (or such other member of the SpinCo Group as SpinCo may designate) shall have the sole right to represent the interests of the members of the SpinCo Group and to employ
counsel of its choice at its expense in any Proceeding relating to SpinCo Separate Returns. 
 (c) Power of Attorney.
Each member of the SpinCo Group shall execute and deliver to Parent (or such other member of the Parent Group as Parent may designate) any power 

  
 24 

 
of attorney or other document requested by Parent (or such designee) in connection with any Proceeding described in the first sentence of Section 6(b). 

(d) Tax Matters Partner. The parties agree to cause MOC to be the “tax matters partner” (as defined under Code
Section 6231(a)(7)) of MPC LP for all taxable periods ending on or before December 31, 2010, and to cause MPC Investment LLC to be the tax matters partner for any Straddle Period of MPC LP. Notwithstanding the appointment of the tax
matters partner as provided in the preceding sentence, the parties agree to take all actions necessary to enable the parties designated in Section 6(b) to control any Proceedings as set forth in Section 6(b). 

(e) Distribution-Related Proceedings, Proceedings with Respect to SpinCo Tax Liabilities. 

(i) In the event of any Distribution-Related Proceeding or Proceeding relating to a SpinCo Tax Liability as a result of
which SpinCo could reasonably be expected to become liable for Tax or any Tax-Related Losses and with respect to which Parent has the right to represent the interests of the members of the Parent Group and/or the members of the SpinCo Group pursuant
to Section 6(b) above, (A) Parent shall consult with SpinCo reasonably in advance of taking any significant action in connection with such Proceeding, (B) Parent shall consult with SpinCo and offer SpinCo a reasonable opportunity to
comment before submitting any written materials prepared or furnished in connection with such Proceeding, (C) Parent shall defend such Proceeding diligently and in good faith as if it were the only party in interest in connection with such
Proceeding, and (D) Parent shall provide SpinCo copies of any written materials relating to such Proceeding received from the relevant Tax Authority. Notwithstanding anything in the preceding sentence to the contrary, the final determination of
the positions taken, including with respect to settlement or other disposition, in (i) any Distribution-Related Proceeding, or (ii) any other Proceeding relating to a Tax Return described in Section 6(b) with respect to which Parent
is entitled to represent the interests of the members of the Parent Group and/or the members of the SpinCo Group, shall be made in the sole discretion of Parent and shall not be subject to the Dispute Resolution provisions of Section 9.

 (ii) In the event of any Distribution-Related Proceeding with respect to any SpinCo Separate Return,

 7.
Apportionment of Tax Attributes; Carrybacks. 
 (a) Apportionment of Tax Attributes. 

(i) If the Parent Consolidated Group has a Tax Attribute, the portion, if any, of such Tax Attribute apportioned to SpinCo
or any other member of the SpinCo Consolidated Group and treated as a carryover to the first Post-Distribution Taxable Period of SpinCo (or such member) shall be determined by Parent in accordance with Treasury Regulation Sections 1.1502-9T,
1.1502-21, 1.1502-21T, 1.1502-22, 1.1502-79 and, if applicable, l.1502-79A. 
 (ii) No Tax Attribute with respect
to consolidated U.S. federal Income Tax of the Parent Consolidated Group, other than those described in Section 7(a)(i), and no Tax Attribute with respect to consolidated, combined or unitary state, local or foreign Income Tax, in each case,
arising in respect of a Combined Return shall be apportioned to SpinCo or any other member of the SpinCo Group, except as Parent (or such other member of the Parent Group as Parent may designate) determines is otherwise required under applicable
law. 
 (iii) Parent (or its designee) shall determine the portion, if any, of any Tax Attribute which must
(absent a Final Determination to the contrary) be apportioned to SpinCo or any other member of the SpinCo Group in accordance with this Section 7(a) and applicable law, and the amount of earnings and profits to be apportioned to SpinCo or any
other member of the SpinCo Group in accordance with applicable law. 
 (iv) Except as otherwise required by
applicable law or pursuant to a Final Determination, no member of the SpinCo Group shall take any position (whether on a Tax Return or otherwise) that is inconsistent with the apportionment by Parent in Section 7(a)(iii). 

(b) Carrybacks. Except to the extent otherwise consented to by Parent or prohibited by applicable law, SpinCo and each other
member of the SpinCo Group shall elect to relinquish, waive or otherwise forgo all Carrybacks. In the event that SpinCo (or the appropriate other member of the SpinCo Group) is prohibited by applicable law to relinquish, waive or otherwise forgo a
Carryback (or Parent consents to a Carryback), (i) Parent shall cooperate with SpinCo, at SpinCo’s expense, in seeking from the appropriate Tax Authority such Refund as reasonably would result from such Carryback, and (ii) SpinCo
shall be entitled to any Income 

  
 26 

 
Tax Benefit Actually Realized by a member of the Parent Group (including any interest thereon received from such Tax Authority), to the extent that such Refund is directly attributable to such
Carryback, within 15 Business Days after such Refund is Actually Realized; provided, however, that SpinCo shall indemnify and hold the members of the Parent Group harmless from and against any and all collateral Tax consequences resulting
from or caused by any such Carryback, including (but not limited to) the loss or postponement of any benefit from the use of Tax Attributes generated by a member of the Parent Group or an Affiliate thereof if (x) such Tax Attributes expire
unutilized, but would have been utilized but for such Carryback, or (y) the use of such Tax Attributes is postponed to a later taxable period than the taxable period in which such Tax Attributes would have been utilized but for such Carryback.

 8. Cooperation and Exchange of Information. 

(a) Cooperation and Exchange of Information. Each of Parent and SpinCo, on behalf of itself and each other member of the Parent
Group and the SpinCo Group, respectively, agrees to provide the other party (or its designee) with such cooperation or information as such other party (or its designee) reasonably shall request in connection with the determination of any payment or
any calculations described in this Agreement, the preparation or filing of any Income Tax Return or Other Tax Return or claim for Refund, or the conduct of any Proceeding. Such cooperation and information shall include, upon reasonable notice,
(i) promptly forwarding copies of appropriate notices and forms or other communications (including information document requests, revenue agent’s reports and similar reports, notices of proposed adjustments and notices of deficiency)
received from or sent to any Tax Authority or any other administrative, judicial or governmental authority, (ii) providing copies of all relevant Income Tax Returns or Other Tax Returns, together with accompanying schedules and related
workpapers, documents relating to rulings or other determinations by any Tax Authority, and such other records concerning the ownership and Tax basis of property, or other relevant information, (iii) the provision of such additional information
and explanations of documents and information provided under this Agreement (including statements, certificates, forms, returns and schedules delivered by either party) as shall be reasonably requested by Parent (or its designee) or SpinCo (or its
designee), as the case may be, (iv) the execution of any document that may be necessary or reasonably helpful in connection with the filing of an Income Tax Return or Other Tax Return, a claim for a Refund, or in connection with any Proceeding,
including such waivers, consents or powers of attorney as may be necessary for Parent or SpinCo, as the case may be, to exercise its rights under this Agreement, and (v) the use of Parent’s or SpinCo’s, as the case may be, reasonable
efforts to obtain any documentation from a governmental authority or a Third Party that may be necessary or reasonably helpful in connection with any of the foregoing. It is expressly the intention of the parties to this Agreement to take all
actions that shall be necessary to establish Parent as the sole agent for Income Tax or Other Tax purposes of each member of the SpinCo Group with respect to all Combined Returns. Upon reasonable notice, each of Parent and SpinCo shall make its, or
shall cause the other members of the Parent Group or the SpinCo Group, as applicable, to make their, employees and facilities available on a mutually convenient basis to provide explanation of any documents or information provided hereunder. Any
information obtained under this Section 8 shall be kept confidential, except as otherwise reasonably may be necessary in connection with the filing of Income Tax Returns or Other Tax Returns or claims for Refund or in conducting any Proceeding.

  
 27 

 (b) Retention of Records. Each of Parent and SpinCo agrees to retain all Income Tax
Returns and Other Tax Returns, related schedules and workpapers, and all material records and other documents as required under Section 6001 of the Code and the regulations promulgated thereunder (and any similar provision of state, local or
foreign law) existing on the date hereof or created in respect of (i) any Pre-Distribution Taxable Period or (ii) any taxable period that may be subject to a claim hereunder, in each case, until the later of (A) the expiration of the
statute of limitations (including extensions) for the taxable periods to which such Income Tax Returns, Other Tax Returns and other documents relate and (B) the Final Determination of any payments that may be required in respect of such taxable
periods under this Agreement. 
 9. Resolution of Disputes. Parent and SpinCo shall attempt in good faith to
resolve any disagreement arising with respect to this Agreement, including any dispute in connection with a claim by a Third Party (a “Tax Dispute”). Any party to this Agreement may give any other party hereto written notice of any Tax
Dispute not resolved in the normal course of business. If the parties cannot agree by the tenth Business Day following the date on which one party gives such notice, then the parties shall promptly retain the services of a nationally recognized law
or accounting firm reasonably acceptable to the parties (the “Tax Dispute Arbitrator”). The Tax Dispute Arbitrator shall be instructed to resolve the Tax Dispute, and such resolution shall be (a) set forth in writing and signed by the
Tax Dispute Arbitrator, (b) delivered to each party involved in the Tax Dispute as soon as practicable after the Tax Dispute is submitted to the Tax Dispute Arbitrator, but no later than the fifteenth Business Day after the Tax Dispute
Arbitrator is instructed to resolve the dispute, (c) made in accordance with this Agreement, and (d) final, binding and conclusive on the parties involved in the Tax Dispute on the date of delivery of such resolution. The Tax Dispute
Arbitrator shall only be authorized on any one issue to decide in favor of and choose the position of either of the parties involved in the Tax Dispute or to decide upon a compromise position between the ranges presented by the parties to the Tax
Dispute Arbitrator. The fees and expenses of the Tax Dispute Arbitrator shall be borne 50% by Parent and 50% by SpinCo. 
 10.
Payments. 
 (a) Method of Payment. All payments required by this Agreement shall be made by (i) wire
transfer to the appropriate bank account as may from time to time be designated by the respective parties for such purpose; provided, however, that, on the date of such wire transfer, notice of the transfer is given to the recipient thereof
in accordance with Section 11, or (ii) any other method agreed to by the parties. All payments due under this Agreement shall be deemed to be paid when available funds are actually received by the payee. 

(b) Interest. Any payment required by this Agreement that is not made on or before the date required hereunder shall bear
interest, from and after such date through the date of payment, at the Underpayment Rate. 
 (c) Characterization of
Payments. For all tax purposes, the parties hereto agree to treat, and to cause their respective Affiliates to treat any payment required by this Agreement as either a contribution by Parent to SpinCo or a distribution by SpinCo to Parent, as

  
 28 

 
the case may be, occurring immediately prior to the Spin-Off, except as otherwise mandated by applicable law or a Final Determination; provided, however, that in the event it is determined
(i) pursuant to applicable law, or (ii) pursuant to a Final Determination, that any such treatment is not permissible (or that an Indemnified Party nevertheless suffers an Income Tax or Other Tax detriment as a result of such payment), the
payment in question shall be adjusted to place the Indemnified Party in the same after-tax position it would have enjoyed absent such applicable law or Final Determination. 
 11. Notices. Notices, requests, permissions, waivers, and other communications hereunder shall be in writing and shall be deemed to have been duly given upon (a) a transmitter’s
confirmation of a receipt of a facsimile transmission (but only if followed by confirmed delivery of a standard overnight courier the following Business Day or if delivered by hand the following Business Day), or (b) confirmed delivery of a
standard overnight courier or delivered by hand, to the parties at the following addresses (or at such other addresses for a party as shall be specified by like notice):

 Section 13.2 Treatment of Outstanding MRO Unvested Options. 

(a) All Holders Other than MPC Employees and Speedway Employees. Each MRO Unvested Option outstanding under the MRO Stock Plans at
the Effective Time which is held by any Person other than an MPC Employee or a Speedway Employee shall remain an option to purchase Marathon Oil common stock issued under the applicable MRO Stock Plan (each such option, a “Remaining MRO
Unvested Option”). Except as provided in this Section 13.2(a), each Remaining MRO Unvested Option shall be subject to the same terms and conditions after the Effective Time as the terms and conditions applicable to the corresponding
MRO Unvested Option immediately prior to the Effective Time. The exercise price and number of shares subject to each Remaining MRO Unvested Option shall be adjusted by action of the Board of Directors or Marathon Oil under the applicable MRO Stock
Plan as follows: (i) the per-share exercise price of each such Remaining MRO Unvested Option shall be equal to the product of (x) the per-share exercise price of the corresponding MRO Unvested Option immediately prior to the Effective Time
and (y) the MRO Price Ratio, rounded up or down to the nearest whole cent, with one-half cents being rounded up (the “MRO Adjusted Exercise Price”) and (ii) the number of shares of Marathon Oil common stock subject to each
such Remaining MRO Unvested Option shall be equal to the product of (x) the number of shares of Marathon Oil common stock subject to the corresponding MRO Unvested Option immediately prior to the Effective Time and (y) the quotient
obtained by dividing (A) the excess of the MRO Pre-Distribution Stock Value over the original exercise price of such MRO Unvested Option by (B) the excess of the MRO Post-Distribution Stock Value over the MRO Adjusted Exercise Price, with
any fractional share rounded down to the nearest whole share. 
 (b) MPC Employees and Speedway Employees. Each MRO
Unvested Option outstanding under the MRO Stock Plans which is held by an MPC Employee or Speedway Employee at the Effective Time shall be converted as of the Effective Time into an option to purchase shares of Marathon Petroleum common stock (each
such option, an “MPC Unvested Option”) pursuant to the terms of the MPC Incentive Compensation Plan subject to terms and conditions after the Effective Time that are substantially similar to the terms and conditions applicable to
the corresponding MRO Unvested Option immediately prior to the Effective Time, except as provided in this Section 13.2(b). The exercise price and number of shares subject to such MPC Unvested Option shall be determined as follows: (i) the
per-share exercise price of each such MPC Unvested Option shall be equal to the product of (x) the per-share exercise price of the corresponding MRO Unvested Option immediately prior to the Effective Time and (y) the MPC Price Ratio,
rounded up or down to the nearest whole cent, with one-half cents being rounded up (the “MPC Adjusted Exercise Price”) and (ii) the number of shares of Marathon Petroleum common stock subject to each such MPC Unvested Option
shall be equal to the product of (x) the number of shares of Marathon Oil common stock subject to the corresponding MRO Unvested Option immediately prior to the Effective Time and (y) the quotient obtained by dividing (A) the excess
of the MRO Pre-Distribution Stock Value over the original exercise price of such MRO Unvested Option by (B) the excess of the MPC Stock Value over the MPC Adjusted Exercise Price, with any fractional share rounded down to the nearest whole
share. 
 (c) Delayed Transfer Employees. 

(i) Each MRO Unvested Option held by a Delayed Transfer Employee who is an MRO Employee shall be adjusted under
Section 13.2(a) on the same basis as any other MRO Unvested Option. Each MRO Unvested Option held by a Delayed Transfer Employee who is an MPC Employee shall be adjusted under Section 13.2(b) on the same basis as any other MRO Unvested
Option held by other MPC Employees. 
 (ii) Each Remaining MRO Unvested Option outstanding under the MRO Stock
Plans held by a Delayed Transfer Employee who transfers from the MRO Group to the MPC Group 

  
 Page 25 of 35

 
shall be converted as of such Transfer Date into an option to purchase shares of Marathon Petroleum common stock (each such option, a “Delayed Transfer MPC Option”) pursuant to
the terms of the MPC Incentive Compensation Plan and shall be subject to terms and conditions after such Delayed Transfer Employee’s Transfer Date that are substantially similar to the terms and conditions applicable to the corresponding
Remaining MRO Unvested Option immediately prior to such Delayed Transfer Employee’s Transfer Date, except as provided in this Section 13.2(c)(ii). The exercise price and number of shares subject to such Delayed Transfer MPC Option shall be
determined as follows: (A) the per-share exercise price of each such Delayed Transfer MPC Option shall be equal to the product of (x) the per-share exercise price of the corresponding Remaining MRO Unvested Option immediately prior to such
Delayed Transfer Employee’s Transfer Date and (y) the MPC Delayed Price Ratio, rounded up or down to the nearest whole cent with one-half cents being rounded up and (B) the number of shares of Marathon Petroleum common stock subject
to each such Delayed Transfer MPC Option shall be equal to the product of (x) the number of shares of Marathon Oil common stock subject to the corresponding Remaining MRO Unvested Option immediately prior to such Delayed Transfer
Employee’s Transfer Date and (y) the quotient obtained by dividing (I) the excess of the mean average of the high and low NYSE consolidated transactions system trading prices of Marathon Oil common stock on the last Trading Day on the
NYSE immediately before such Delayed Transfer Employee’s Transfer Date over the exercise price of the Remaining MRO Unvested Option by (II) the excess of the mean average of the high and low NYSE consolidated transactions system trading prices
of Marathon Petroleum common stock on the last Trading Day on the NYSE immediately before such Delayed Transfer Employee’s Transfer Date over the exercise price for the Delayed Transfer MPC Option, as determined under clause (A) of this
Section 13.2(c)(ii), with fractional shares rounded down to the nearest whole share.

Unvested Option outstanding under the MPC Incentive Compensation Plan held by a Delayed Transfer Employee who transfers from the MPC Group to the MRO Group shall be converted as of such Transfer Date into an option to purchase shares of Marathon Oil
common stock (each such option, a “Delayed Transfer MRO Option”) pursuant to the terms of the Marathon Oil Corporation 2007 Incentive Compensation Plan and shall be subject to terms and conditions after such Delayed Transfer
Employee’s Transfer Date that are substantially similar to (to the extent practicable) the terms and conditions applicable to the corresponding MPC Unvested Option immediately prior to such Delayed Transfer Employee’s Transfer Date, except
as provided in this Section 13.2(c)(iii). The exercise price and number of shares subject to such Delayed Transfer MRO Option shall be determined as follows: (A) the per-share exercise price of each such Delayed Transfer MRO Option shall
be equal to the product of (x) the per-share exercise price of the corresponding MPC Unvested Option immediately prior to such Delayed Transfer Employee’s Transfer Date and (y) the MRO Delayed Price Ratio, rounded up or down to the
nearest whole cent with one-half cents being rounded up and (B) the number of shares of Marathon Oil common stock subject to each such Delayed Transfer MRO Option shall be equal to the product of (x) the number of shares of Marathon
Petroleum common stock subject to the corresponding MPC Unvested Option immediately prior to such Delayed Transfer Employee’s Transfer Date and (y) the quotient obtained by dividing (I) the excess of the mean average of the high and
low NYSE consolidated transactions system trading prices of Marathon Petroleum common stock on the last Trading Day on the NYSE immediately before such Delayed Transfer Employee’s Transfer Date over the exercise price of the MPC Unvested Option
by (II) the excess of the mean average of the high and low NYSE consolidated transactions system trading prices of Marathon Oil common stock on the last Trading Day on the NYSE immediately before such Delayed Transfer Employee’s Transfer Date
over the exercise price for the Delayed Transfer MRO Option, as determined under clause (A) of this Section 13.2(c)(iii), with fractional shares rounded down to the nearest whole share.
