Marathon Petroleum Company LLC Amended and Restated Excess Benefit Plan

 EXHIBIT 10.29 
 MARATHON PETROLEUM COMPANY LLC 
 EXCESS BENEFIT PLAN 
 Amended and Restated As Of 
 January 1,
2009 

 EXCESS BENEFIT PLAN 
 ARTICLE I. Purpose 
 The Marathon Oil Company Excess Benefit Plan was established February 5, 1976 and has
been amended from time to time. Its stated purpose is to compensate employees for the loss of benefits under the Retirement Plan of Marathon Oil Company and the Marathon Oil Company Thrift Plan that occur due to limitations placed by the Internal
Revenue Code on benefits payable and contributions permitted under qualified plans. These limitations include Code section 415, Code section 401(k), Code section 401(m), Code section 402(g), and Code section 401(a)(17). 
 On January 1, 1998, Marathon Oil Company and Ashland Petroleum Inc. entered into a joint venture, called Marathon Ashland Petroleum LLC (“MAPLLC”). As a
result of the formation of the joint venture and the transfer of a significant number of Marathon employees to MAPLLC, on April 1, 1998 a portion of the Marathon Oil Company Retirement Plan was spun off to create the Marathon Ashland Petroleum
LLC Retirement Plan (“Retirement Plan”). Consistent with that action and pursuant to the agreement of the parties, Excess Retirement Benefits and Excess Thrift Benefits under the Marathon Oil Company Excess Benefit Plan for employees who
transferred to MAPLLC during the 1998 calendar year were spun-off to create the Marathon Ashland Petroleum LLC Excess Benefit Plan. Any elections in effect under the Marathon Oil Company Excess Benefit Plan (such as beneficiary designations or Group
I employee elections, etc.) continued to apply under the MAPLLC Excess Benefit Plan, until and unless changed. The terms and conditions of this MAPLLC Excess Benefit Plan were substantially the same as the terms and conditions of the Marathon Excess
Benefit Plan. 
 Effective September 1, 2005, Marathon Ashland Petroleum LLC changed its name to Marathon Petroleum Company LLC (“MPC” or
“the Company”). Therefore, “MAP” has been replaced with “MPC” throughout this document, and all references to MPC are one and the same with respect to previous references to MAP. The name change from MAP to MPC does not
affect any benefits under this Plan. 
 Effective January 1, 2006, this Excess Benefit Plan was restated to incorporate prior amendments. 
 Effective January 1, 2009, this document is restated and shall apply only to benefits that are not fully distributed as of such date, including both 409A Accruals
and Grandfathered Accruals. With respect to the 409A Accruals, the Excess Benefit Plan, as amended and restated, is intended to conform to the requirements of Code section 409A, and, in all respects, shall be administered and construed in accordance
with such requirements. With respect to the Grandfathered Accruals, the Excess Benefit Plan, as amended and restated, does not represent a material enhancement of the benefits or rights available under the Excess Benefit Plan on October 3,
2004. 

 This Excess Benefit Plan sets forth the terms and conditions under which benefits designed to compensate Employees for
the aforementioned losses of benefits shall be accrued and paid by the applicable Employer. Capitalized terms, unless otherwise specified, are defined under the Retirement Plan and the Thrift Plan. In addition, for purposes of this Article I
and the remainder of this Plan, the following definitions apply: 
 “409A Accruals” means those benefits that were accrued after or became
vested after 2004, as adjusted for interest or changes in present value, as applicable. Such amounts shall be determined in accordance with Code section 409A. 
 “Code” means the Internal Revenue Code. 
 “Code section 409A” means section 409A of the Code and any Treasury and
Internal Revenue Service regulations and guidance issued thereunder. 
 “Company” means Marathon Petroleum Company LLC. 
 “Employee” means any individual employed by an Employer. 
 “Employer” includes the Company and each related company or business which is part of the same controlled group under Code sections 414(b) or 414(c); provided that where specified by the Employer in accordance with Code
section 409A in applying Code section 1563(a)(1) – (a)(3) for purposes of determining a controlled group of corporations under Code section 414(b) and in applying Treasury Regulation section 1.414(c)-2 for purposes of determining whether trades
or businesses are under common control under Code section 414(c), the phrase “at least 50 percent” is used instead of “at least 80 percent.” In addition, the term “Employer” shall also include any entity that previously
met the requirements of an “Employer” as set forth herein that continues to employ a Participant to the extent so designated by the Plan Administrator. 
 “Excess Benefit Plan” means the Marathon Petroleum Company LLC Excess Benefit Plan. 
 “Grandfathered Accruals”
means those benefits that are exempt from Code section 409A because they were accrued and vested before January 1, 2005, as adjusted for interest or changes in present value, as applicable. Such amounts shall be determined in accordance with
Code section 409A. 
 “Retirement Plan” means the Refining, Marketing and Transportation Sub-Plan of the Marathon Petroleum Company LLC
Retirement Plan. 
 “Separation from Service” shall have the same meaning as set forth under Code section 409A with respect to an Employer.

 “Specified Employee” shall have the meaning as set forth under Code section 409A and as determined by the Employer in accordance with its
established policy. 

 “Thrift Plan” means the Marathon Oil Company Thrift Plan.

	 	(2)	The amount of benefit which such Participant or Beneficiary is entitled to receive under the Retirement Plan.

	 	(2)	An amount as normally determined under the Retirement Plan, plus any retirement benefit otherwise payable under the Excess Benefit Plan (i.e., exclusive of any benefits
attributable to the calculation in Section 3.1(b)(1) above). 

 For purposes of the calculations in (1) and
(2) of this Section 3.1(b) “Eligible Grandfather Employee” means any MPC employee eligible for Special Excess Bonus Recognition under Article III, Section A of this Plan prior to October 1, 2006. However, an

becomes effective as determined by the Plan Administrator; less 
 (b) The amount of Company Contributions actually credited to the
Participant’s Thrift Plan account for such year. 
  

	3.3	Payment of Excess Benefit 

 A Participant shall be entitled to a
cash distribution of the Participant’s Excess Retirement Benefit and Excess Thrift Benefit, as applicable (collectively, the “Excess Benefit”), as provided in this Section 3.3. 
 (a) Except as otherwise provided in this Section 3.3, a Participant’s Excess Benefit shall be paid in a lump sum within 90 days of Separation
from Service for any reason other than death. 
 (b) In the event of the death of a Participant, the Participant’s Excess Benefit shall
be paid to the Participant’s applicable Beneficiary in a lump sum within 90 days of the Participant’s death or, if earlier, within the 90-day period following the Participant’s Separation from Service as described in
Section 3.3(a) (or, in the event of a Separation from Service of a Specified 

 
Employee (as defined below) not on account of death, the 90-day period described in Section 3.3(c)). The Participant’s “Beneficiary”
shall be: (i) with respect to the Participant’s Excess Retirement Benefit, the Beneficiary will be his or her Eligible Surviving Spouse or estate (if no Eligible Surviving Spouse); and (ii) with respect to the Participant’s
Excess Thrift Benefit, the Participant’s Beneficiary will be the beneficiary or beneficiaries designated under the Thrift Plan. In any event, if there is no valid Beneficiary under the terms of this Excess Benefit Plan, the Excess Benefit will
be paid to the person or persons comprising the first surviving class of the eligible classes as set forth: (1) the Participant’s spouse; (2) the Participant’s natural born and legally adopted children; (3) the
Participant’s surviving parents; (4) the Participant’s surviving brothers and sisters; and (5) the executor or administrator of the Participant’s estate. 
 (c) Distribution of the Excess Benefit of a Participant who the Plan Administrator determines is a Specified Employee (other than such Participant’s
Grandfathered Accruals) shall be paid in a lump sum within the 90-day period following the first of the month following 6 months after Separation from Service (other than a Separation from Service on account of the death of Participant). In the
event of a Separation from Service of a Specified Employee on account of death, payment shall be made pursuant to Section 3.3(b). Payment of a Specified Employee’s Grandfathered Accruals shall be made in accordance with
Section 3.3(a). 
 (d) A Participant must be vested under the Retirement Plan in order for an Excess Retirement Benefit to be payable.
The amount of any lump sum payment hereunder shall be determined by using the same factors and assumptions which would be used by the Retirement Plan for such Participant or Beneficiary at the Participant’s Separation from Service. The balance
of any Excess Retirement Benefit not paid at the Participant’s Separation from Service shall accrue interest beginning at the Participant’s Separation from Service at a rate used under the Retirement Plan to determine the actuarial
equivalent lump sum of a life only monthly annuity. 
 (e) A Participant must be fully vested under the Thrift Plan in order for an Excess
Thrift Benefit to be payable. The balance of any Excess Thrift Benefit not paid at the Participant’s Separation from Service shall accrue interest at the “Cash with Interest” rate provided under Article VIII of the Thrift Plan until
the entire balance has been paid. If the “Cash with Interest” rate becomes unavailable for any reason, whether for purposes of this Section 3.3(e) or for purposes of Section 3.2, the Company shall, at its sole discretion,
substitute a similar interest rate which will be applicable for time periods thereafter. 
 (f) Distributions of 409A Accruals prior to
January 1, 2009 were made under reasonable good faith interpretations of Code section 409A and transition guidance provided thereunder. Notwithstanding any contrary provisions of this Section 3.3, to the extent the Plan Administrator
permitted a Participant to submit an election to receive payment in a form of distribution other than a lump sum and such payment commenced prior to 2009, the distribution of such Participant’s Excess Benefit after 2008 shall be governed by
procedures established by the Plan Administrator. 

 ARTICLE IV. Funding 
 Benefits under this Excess Benefit Plan shall be paid from the general assets of the applicable Employer. This Excess Benefit Plan shall be administered as an unfunded plan which is maintained primarily for the purpose of providing
supplemental retirement compensation “for a select group of management or highly compensated employees” as set forth in sections 201(2), 301(3), and 401(a)(1) of ERISA, and is not intended to meet the qualification requirements of section
401 of the Code. Any assets set aside by the Employer for the purpose of paying benefits under this Excess Benefit Plan shall not be deemed to be the property of the Participant and shall be subject to claims of creditors of the Employer. No
Participant or other person shall have any claim against, right to, or security or other interest in, any fund, account or asset of the Employer from which any payment under the Excess Benefit Plan may be made. Any use of the words
“contributions” or “contribute,” or any similar phrase, shall not require actual contributions or funding of this Excess Benefit Plan and is only used for convenience when describing the deferral activities of this Excess Benefit
Plan. 
 ARTICLE V. Plan Administration 
  

	5.1	General Duty 

 The Company has delegated its administrative
authority hereunder to the Plan Administrator of the Retirement Plan or its successor (the “Plan Administrator.”) It shall be the principal duty of the Plan Administrator to determine that the provisions of the Excess Benefit Plan are
carried out in accordance with its terms, for the exclusive benefit of persons entitled to participate in the Excess Benefit Plan. 
  

	5.2	Plan Administrator’s General Powers, Rights and Duties 

 The
Plan Administrator shall have full power to administer the Excess Benefit Plan in all of its details, subject to the applicable requirements of law. For this purpose, the Plan Administrator is, as respects the rights and obligations of all parties
with an interest in this Excess Benefit Plan, given the powers, rights and duties specifically stated elsewhere in the Excess Benefit Plan, or any other document, and in addition is given, but not limited to, the following powers, rights and duties:

 (a) to determine all questions arising under the Excess Benefit Plan, including the power to determine the rights or eligibility of
Employees or Participants and any other persons, and the amounts of their contributions or benefits under the Excess Benefit Plan, to interpret the Excess Benefit Plan, and to remedy ambiguities, inconsistencies or omissions; 

 (b) to adopt such rules of procedure and regulations, including the establishment of any claims procedure
that may be required by law, as in its opinion may be necessary for the proper and efficient administration of the Excess Benefit Plan and as are consistent with the Excess Benefit Plan; 
 (c) to direct payments or distributions from the Excess Benefit Plan in accordance with the provisions of the Excess Benefit Plan; 
 (d) to develop such information as may be required by it for tax or other purposes as respects the Excess Benefit Plan; and 
 (e) to employ agents, attorneys, accountants or other persons (who also may be employed by the Company), and allocate or delegate to them such powers as
the Plan Administrator may consider necessary or advisable to properly carry out the administration of the Excess Benefit Plan. 
 The Plan
Administrator’s decision in any matter involving the interpretation and application of this Excess Benefit Plan shall be final and binding. In the event the Plan Administrator would have to decide any issue under the Excess Benefit Plan which
could affect the form or timing of the payment of deferred compensation under the Excess Benefit Plan, then the Company shall make that decision. 
  

	5.3	Indemnification of Administrator 

 The Company agrees to indemnify
and to defend to the fullest extent permitted by law any Employee serving as the Plan Administrator against all liabilities, damages, costs and expenses (including attorney’s fees and amounts paid in settlement of any claims approved by the
Company) occasioned by any act of omission to act in connection with the Excess Benefit Plan, if such act of omission is or was in good faith. This Section 5.3 shall comply with Code section 409A and Treasury Regulation section
1.409A-3(i)(1)(iv) with regard to the requirements for reimbursements, to the extent applicable, for the period that such Employee’s indemnification right hereunder shall exist. 
  

	5.4	Information Required by Plan Administrator 

 The Plan Administrator
shall obtain such data and information as deemed necessary or desirable in order to administer the Excess Benefit Plan. The records of the Company as to an Employee’s or Participant’s period or periods of employment, termination of
employment and the reason therefor, leave of absence, re-employment and earnings will be conclusive on all persons unless determined by independent agents or delegates of the Plan Administrator to be incorrect. Participants and other persons
entitled to benefits under the Excess Benefit Plan also shall furnish the Plan Administrator with such evidence, data or information, as the Plan Administrator considers necessary or desirable to administer the Excess Benefit Plan. 

	5.5	Claims and Review Procedures 

 (a) Claims
Procedure. If a Participant believes any rights or benefits are being improperly denied under the Excess Benefit Plan, such Participant may file a claim in writing with the Plan Administrator. If any such claim is wholly or partially denied,
the Plan Administrator shall notify such Participant of its decision in writing. Such notification shall be written in a manner calculated to be understood by such Participant and shall contain (i) specific reasons for the denial,
(ii) specific reference to pertinent Excess Benefit Plan provisions, (iii) a description of any additional material or information necessary for the Participant to perfect such claim and an explanation of why such material or information
is necessary, and (iv) information as to the steps to be taken if the Participant wishes to submit a request for review. Such notification shall be given within 90 days after the claim is received by the Plan Administrator (or within 180 days,
if special circumstances require an extension of time for processing the claim, and if written notice of such extension and circumstances is given to such Participant within the initial 90 day period.) If such notification is not given within such
period the claim shall be considered denied as of the last day of such period and such Participant may request a review of his claim. 
 (b)
Review Procedure. Within 60 days after the date on which a Participant receives a written notice of a denied claim (or, if applicable, within 60 days after the date on which such denial is considered to have occurred) such Participant (or the
Participant’s duly authorized representative) may (i) file a written request with the Plan Administrator for a review of his denied claim and of pertinent documents, and (ii) submit written issues and comments to the Plan
Administrator. The Plan Administrator shall notify such Participant of its decision in writing. Such notification shall be written in a manner calculated to be understood by such Participant and shall contain specific reasons for the decision as
well as specific references to pertinent Excess Benefit Plan provision. The decision on review shall be made within 60 days after the request for review is received by the Plan Administrator (or within 120 days, if special circumstances require an
extension of time for processing the request, such as an election by the Plan Administrator to hold a hearing, and if written notice of such extension and circumstances is given to such person within the initial 60 day period). If the decision on
review is not made within such period, the claim shall be considered denied. 
 (c) Section 409A Requirements. Any claim for benefits
under this Section must be made by the Participant no later than the time prescribed by Code section 409A. If a claimant’s claim or appeal is approved, any resulting payment of benefits will be made no later than the time prescribed for payment
of benefits by Code Section 409A. 

 ARTICLE VI. Modification and Discontinuance 
  

	6.1	Amendment and Termination 

 The Company reserves the right to
modify, suspend, or terminate the Excess Benefit Plan at any time, in whole or in part, in such manner as it shall determine, provided that such action conforms to the requirements of Code section 409A. Included in the Company’s right to amend,
suspend or terminate is the Company’s right at any time to no longer permit any additional Participants under the Excess Benefit Plan, to cease benefit accruals, and to distribute all benefits upon Excess Benefit Plan termination, all subject
to the requirements of Code section 409A. The Plan Administrator may promulgate rules and procedures from time to time to carry out the provisions of this Article VI. However, in no event shall the Company have the right to eliminate or reduce any
benefit, which has been vested or become forfeitable under the Excess Benefit Plan. No future amendment to the Excess Benefit Plan shall apply to Grandfathered Accruals to the extent such provision or amendment would constitute a “material
modification” within the meaning of Code section 409A with respect to the Grandfathered Accruals unless such amendment expressly indicates otherwise. 
  

	6.2	Delegation of Authority 

 In addition to the other methods of
amending MPC’s employee benefit plans, practices, and policies (hereinafter referred to as “MPC Employee Benefit Plans”) which have been authorized, or may in the future be authorized, by the Marathon Oil Company Board of Directors,
the Company’s Vice President of Human Resources may approve the following types of amendments to MPC Employee Benefit Plans: 
 (a) With
the opinion of counsel, technical amendments required by applicable laws and regulations; 
 (b) With the opinion of counsel, amendments that
are clarifications of plan provisions; 
 (c) Amendments in connection with a signed definitive agreement governing a merger, acquisition or
divestiture such that, for MPC Employee Benefit Plans, needed changes are specifically described in the definitive agreement, or if not specifically described in the definitive agreement, the needed changes are in keeping with the intent of the
definitive agreement; 
 (d) Amendments in connection with changes that have a minimal cost impact (as defined below) to the Company; and

 (e) With the opinion of counsel, amendments in connection with changes resulting from state or federal legislative actions that have a
minimal cost impact (as defined below) to the Company. 

 For purposes of the above, “minimal cost impact” is defined as an annual cost impact to the Company per MPC
Employee Benefit Plan case that does not exceed the greater of (i) an amount that is less than one-half of one percent of its documented total cost (including administrative costs) for the previous calendar year, or (ii) $500,000.

  

	6.3	Transfer of Liabilities 

 In the event of a corporate transaction
involving a Participant’s Employer, the liabilities with respect to the Participant’s Excess Benefit may be transferred to the entity or organization that becomes the Participant’s employer following the corporate transaction to the
extent that such transfer (i) is permitted by applicable law, (ii) with respect to the 409A Accruals is consistent with Code section 409A, and (iii) with respect to Grandfathered Accruals, does not represent a material enhancement of
the Participant’s benefits or rights available under the Excess Benefit Plan on October 3, 2004. For these purposes, a corporate transaction shall include, but not be limited to, a merger, consolidation, separation, reorganization,
liquidation, split-up, or spin-off. 
 ARTICLE VII. General Provisions 
  

	7.1	Notices 

 Each Participant entitled to benefits under the Excess
Benefit Plan must file in writing with the Plan Administrator such Participant’s post office address and each change of post office address. Any communication, statement or notice addressed to any such Participant at the last post office
address filed with the Plan Administrator will be binding upon such person for all purposes of the Excess Benefit Plan, and the Plan Administrator shall not be obligated to search for or ascertain the whereabouts of any Participant. Any notice or
document required to be given or filed with the Plan Administrator shall be considered as given or filed if delivered or mailed by registered mail, postage prepaid, to Rodney P. Nichols, Vice President of Human Resources, P. O. Box 1, Findlay, Ohio
45839-0001. 
  

	7.2	Employment Rights 

 The Excess Benefit Plan does not constitute a
contract of employment, and participation in the Excess Benefit Plan will not give any Participant the right to be retained in the employ of the Company or any Employer nor any right or claim to any benefit under the Excess Benefit Plan, unless such
right or claim has specifically accrued under the terms of the Excess Benefit Plan. 
  

	7.3	Interests Not Transferable 

 Except as may be required by law,
including the federal income and employment tax withholding provisions of the Code, or of an applicable state’s income tax act, the interests of Participants and their Beneficiaries under this Excess Benefit Plan are not subject to the claims
of their creditors and may not be voluntarily or involuntarily sold, transferred, alienated, assigned or encumbered. Notwithstanding any provision of the Excess Benefit Plan to the contrary, the Excess Benefit Plan shall not recognize or give effect
to any domestic relations order attempting to alienate, transfer or assign any Participant benefits. The preceding shall not preclude the 

 
Employer from asserting any claim for damages or for any debt that the Employer may have with respect to the Participant; provided that any offset shall
apply only where such debt is incurred in the ordinary course of the service relationship between the Employer and the Participant, the entire amount of reduction in any of the Participant’s taxable years does not exceed $5,000, and the
reduction is made at the same time and in the same amount as the debt otherwise would have been due and collected from the Participant. 
  

	7.4	Facility of Payment 

 When a Participant entitled to benefits under
the Excess Benefit Plan is under a legal disability, or, in the Plan Administrator’s opinion, is in any way incapacitated so as to be unable to manage their financial affairs, the Plan Administrator may direct that the benefits to which such
Participant otherwise would be entitled shall be made to such Participant’s legal representative, or to such other person or persons as the Plan Administrator may direct the application of the benefits for the benefit of such Participant. Any
payment made in accordance with such provisions of this Section 7.4 shall be a full and complete discharge of any liability for such payment. 
  

	7.5	Controlling State Law 

 To the extent not superseded by the laws of
the United States, the laws of the State of Ohio shall be controlling in all matters relating to the Excess Benefit Plan. 
  

	7.6	Severability 

 In case any provisions of the Excess Benefit Plan
shall be held illegal or invalid for any reason, such illegality or invalidity shall not affect the remaining provisions of the Excess Benefit Plan, and the Excess Benefit Plan shall be construed and enforced as if such illegal and invalid
provisions had never been set forth in the Excess Benefit Plan. 
  

	7.7	Statutory References 

 All references to the Code and ERISA include
reference to any comparable or succeeding provisions of any legislation, which amends, supplements or replaces such section or subsection. 
  

	7.8	Headings 

 Section headings and titles are for reference only. In
the event of a conflict between a title and the content of a section, the content of the section shall control. 
  

	7.9	Non-taxable Benefits 

 It is the intention of the Company that this
Excess Benefit Plan meet all requirements of the Code so that the benefits provided be non-taxable during the period of deferral and until actual distribution is made. 
  

	7.10	Affect on Other Benefit Plans 

 Any benefit payable under the
Retirement Plan or the Thrift Plan shall be paid solely in accordance with the terms and provisions of those Plans, and nothing in the Excess Benefit Plan shall operate or be construed in any way to modify, amend, or affect the terms and provisions
of the Retirement Plan or Thrift Plan.

President, Marathon Oil Company, and its corporate seal to be hereto affixed.

 MARATHON PETROLEUM COMPANY LLC 
 DEFERRED COMPENSATION PLAN 
 This document contains the provisions of the

otherwise specified in this Article III. 
 ARTICLE IV. Other Contributions 
  

	4.1.	Thrift Plan Make-up Matching Contributions

(i) continue to contribute their maximum permissible amount to the MSP Account as determined under the Thrift Plan, and (ii) are not suspended from making After-Tax Contributions under the terms of the Thrift Plan, and (c) who submit
an election with the Plan Administrator in accordance with such procedures as the Plan Administrator shall prescribe, consistent with Code section 409A, indicating that the Participant does not wish to contribute the maximum amount of After-Tax
Contributions under the Thrift Plan, will be treated as being subject to the limitations of the Code for purposes of Section 4.1(a) upon making the maximum permissible amount of MSP Contributions.

Code) during the Thrift Plan’s waiting period. This accrual shall cease to the extent that, upon the first date of participation eligibility in the Thrift Plan, the employee is eligible under the Plan for the Thrift Plan Company matching
contributions. 
  

	4.3.	Matching Contributions on Salary Deferrals 

 A
Participant shall be credited each year with a match equal to such Participant’s Salary Deferrals during the year multiplied by the rate of the maximum potential match under the Thrift Plan.

 Any
Salary Deferrals under Article III or matching contributions under Article IV shall be credited to the Participant’s Account in the manner designated by the Plan Administrator.

 A Participant may select from a list of
hypothetical investment options that will be the same as the investment options offered and modified from time to time under the terms of the Thrift Plan. Earnings, gains and losses received on the investments will be credited to the
Participant’s Account in the manner designated by the Plan Administrator. The Plan Administrator shall develop such accounting procedures as it, in its sole discretion, deems advisable to properly reflect the value attributable to the
Participant’s Account. 
 ARTICLE VI. Vesting 
 A Participant’s Salary Deferrals shall always be immediately vested. Matching contributions provided under Article IV shall vest as provided under the terms and conditions of the Thrift Plan.

the Participant’s Account shall be paid to the Participant’s Beneficiary in a lump sum within 90 days of the Participant’s death or, if earlier, within the 90-day period following the Participant’s Separation from Service as

Account shall be credited with earnings and losses pursuant to the provisions set forth in Article V until fully paid.

following 6 months after Separation from Service (other than a Separation from Service on account of the death of Participant). In the event of a Separation from Service of a Specified Employee on account of death, payment shall be made pursuant to
Section 7.2. Payment of a Specified Employee’s Grandfathered Deferrals Sub-Account shall be made in accordance with Section 7.1. 
  

 - 5 - 

	7.5.	Pre-2009 Distributions and Distribution Elections 

 Distributions of 409A Deferrals prior to January 1, 2009 were made under reasonable good faith interpretations of Code section 409A and transition guidance provided thereunder. Notwithstanding any contrary provisions of this
Section 7, to the extent the Plan Administrator permitted a Participant to submit an election to receive payments prior to 2009, the distribution of such Participant’s Account after 2008 shall be governed by procedures established by the
Plan Administrator. 
 ARTICLE VIII. Funding 
 Benefits under this Plan shall be paid from general assets of the Employer. This Plan shall be administered as an unfunded plan which is maintained primarily for the purpose of providing supplemental retirement compensation “for a
select group of management or highly compensated employees” as set forth in sections 201(2), 301(3), and 401(a)(1) of the ERISA, and is not intended to meet the qualification requirements of section 401 of the Code. Any assets set aside by the
Employer for the purpose of paying benefits under this Plan shall not be deemed to be the property of the Participant and shall be subject to claims of creditors of the Employer. No Participant or other person shall have any claim against, right to,
or security or other interest in, any fund, account or asset of the Employer from which any payment under the Plan may be made. Any use of the words “contributions” or “contribute,” or any similar phrase, shall not require actual
contributions or funding of this Plan and is only used for convenience when describing the deferral activities of this Plan.

	9.1.	General Duty 

 The Plan shall be administered by the
Plan Administrator who shall be appointed by the Company and shall serve in such capacity until resignation or removal by the Company. It shall be the principal duty of the Plan Administrator to determine that the provisions of the Plan are carried

their contributions or benefits under the Plan, to interpret the Plan, and to remedy ambiguities, inconsistencies or omissions; 

  

	 	(b)	to adopt such rules of procedure and regulations, including the establishment of any claims procedure that may be required by law, as in its opinion may be necessary for the proper

	 	(e)	to employ agents, attorneys, accountants or other persons (who also may be employed by the Company), and allocate or delegate to them such powers as the Plan Administrator may
consider necessary or advisable to properly carry out the administration of the Plan. 

 The Plan Administrator’s decision
in any matter involving the interpretation and application of this Plan shall be final and binding. In the event the Plan Administrator would have to decide any issue under the Plan which could affect the form or timing of the payment of deferred
compensation under the Plan, then the Company shall make that decision. 
  

	9.3.	Indemnification of Administrator 

 The Company
agrees to indemnify and to defend to the fullest extent permitted by law any Employee serving as the Plan Administrator against all liabilities, damages, costs and expenses (including attorney’s fees and amounts paid in settlement of any claims

1.409A-3(i)(1)(iv) with regard to the requirements for reimbursements, to the extent applicable, for the period that such Employee’s indemnification right hereunder shall exist. 
  

	9.4.	Information Required by Plan Administrator 

 The
Plan Administrator shall obtain such data and information as deemed necessary or desirable in order to administer the Plan. The records of the Company as to an Employee’s or Participant’s period or periods of employment, termination of
employment and the reason therefor, leave of absence, re-employment and earnings will be conclusive on all persons unless determined by independent agents or delegates of the Plan Administrator to be incorrect. Participants and other persons
entitled to benefits under the Plan also shall furnish the Plan Administrator with such evidence, data or information, as the Plan Administrator considers necessary or desirable to administer the Plan. 
  

	9.5.	Claims and Review Procedures 

  

	 	(a)	 Claims Procedure. If a Participant believes any rights or benefits are being improperly denied under the Plan, such Participant may file a claim in writing

Participant and shall contain (i) specific reasons for the denial, (ii) specific reference to pertinent Plan provisions, (iii) a description of any additional material or information necessary for the Participant to 

  

 - 7 - 

	 	 
perfect such claim and an explanation of why such material or information is necessary, and (iv) information as to the steps to be taken if the
Participant wishes to submit a request for review. Such notification shall be given within 90 days after the claim is received by the Plan Administrator (or within 180 days, if special circumstances require an extension of time for processing the
claim, and if written notice of such extension and circumstances is given to such Participant within the initial 90 day period.) If such notification is not given within such period the claim shall be considered denied as of the last day of such
period and such Participant may request a review of his claim. 

  

	 	(b)	Review Procedure. Within 60 days after the date on which a Participant receives a written notice of a denied claim (or, if applicable, within 60 days after the date on which
such denial is considered to have occurred) such Participant (or the Participant’s duly authorized representative) may (i) file a written request with the Plan Administrator for a review of his denied claim and of pertinent documents, and
(ii) submit written issues and comments to the Plan Administrator. The Plan Administrator shall notify such Participant of its decision in writing. Such notification shall be written in a manner calculated to be understood by such Participant
and shall contain specific reasons for the decision as well as specific references to pertinent Plan provision. The decision on review shall be made within 60 days after the request for review is received by the Plan Administrator (or within 120
days, if special circumstances require an extension of time for processing the request, such as an election by the Plan Administrator to hold a hearing, and if written notice of such extension and circumstances is given to such person within the
initial 60 day period). If the decision on review is not made within such period, the claim shall be considered denied. 

  

	 	(c)	Section 409A Requirements. Any claim for benefits under this Section must be made by the Participant no later than the time prescribed by Code section 409A. If a
claimant’s claim or appeal is approved, any resulting payment of benefits will be made no later than the time prescribed for payment of benefits by Code Section 409A.

right to modify, suspend, or terminate the Plan at any time, in whole or in part, in such manner as it shall determine, provided that such action conforms to the requirements of Code section 409A. Included in the Company’s right to amend,
suspend or terminate is the Company’s right at any time to no longer permit any additional Participants under the Plan, to cease making Company allocations, and to distribute all Account balances upon Plan termination, all subject to the
requirements of Code section 409A. The Plan Administrator may promulgate rules and procedures from time to time to carry out the provisions of this Article X. However, in no event shall the Company have the right to eliminate or reduce any benefit,
which has been vested or become forfeitable under the Plan, pursuant to Article VI. No future amendment to the Plan shall apply to Grandfathered Deferrals to the extent such provision or amendment would constitute a “material modification”
within the meaning of Code section 409A with respect to the Grandfathered Deferrals unless such amendment expressly indicates otherwise.

	10.2.  	Delegation of Authority 

 In addition to the other

Company’s Vice President of Human Resources may approve the following types of amendments to MPC Employee Benefit Plans: 
 (a) With the
opinion of counsel, technical amendments required by applicable laws and regulations; 
 (b) With the opinion of counsel, amendments that are
clarifications of plan provisions; 
 (c) Amendments in connection with a signed definitive agreement governing a merger, acquisition or
divestiture such that, for MPC Employee Benefit Plans, needed changes are specifically described in the definitive agreement, or if not specifically described in the definitive agreement, the needed changes are in keeping with the intent of the
definitive agreement; 
 (d) Amendments in connection with changes that have a minimal cost impact (as defined below) to the Company; and

 (e) With the opinion of counsel, amendments in connection with changes resulting from state or federal legislative actions that have a
minimal cost impact (as defined below) to the Company.

transaction to the extent that such transfer (i) is permitted by applicable law, (ii) with respect to the 409A Deferrals is consistent with Code section 409A, and (iii) with respect to Grandfathered Deferrals, does not represent a
material enhancement of the Participant’s benefits or rights available under the Plan on October 3, 2004. For these purposes, a corporate transaction shall include, but not be limited to, a merger, consolidation, separation,
reorganization, liquidation, split-up, or spin-off.

 ARTICLE XI. General Provisions 
  

	11.1.  	Notices 

 Each Participant entitled to benefits
under the Plan must file in writing with the Plan Administrator such Participant’s post office address and each change of post office address. Any communication, statement or notice addressed to any such Participant at the last post office
address filed with the Plan Administrator will be binding upon such person for all purposes of the Plan, and the Plan Administrator shall not be obligated to search for or ascertain the whereabouts of any Participant. Any notice or document required
to be given or filed with the Plan Administrator shall be considered as given or filed if delivered or mailed by registered mail, postage prepaid, to Rodney P. Nichols, Vice President of Human Resources, P. O. Box 1, Findlay, Ohio 45839-0001.

  

	11.2.  	Employment Rights 

 The Plan does not constitute a
contract of employment, and participation in the Plan will not give any Participant the right to be retained in the employ of the Employer or any Affiliated Company nor any right or claim to any benefit under the Plan, unless such right or claim has
specifically accrued under the terms of the Plan. 
  

	11.3.  	Interests Not Transferable 

 Except as may be
required by law, including the federal income and employment tax withholding provisions of the Code, or of an applicable state’s income tax act, the interests of Participants and their beneficiaries under this Plan are not subject to the claims
of their creditors and may not be voluntarily or involuntarily sold, transferred, alienated, assigned or encumbered. Notwithstanding any provision of the Plan to the contrary, the Plan shall not recognize or give effect to any domestic relations
order attempting to alienate, transfer or assign any Participant benefits. The preceding shall not preclude the Employer from asserting any claim for damages or for any debt that the Employer may have with respect to the Participant; provided that
any offset shall apply only where such debt is incurred in the ordinary course of the service relationship between the Employer and the Participant, the entire amount of reduction in any of the Participant’s taxable years does not exceed
$5,000, and the reduction is made at the same time and in the same amount as the debt otherwise would have been due and collected from the Participant. 
  

	11.4.  	No Interest or Earnings 

 No interest or earnings of
any type shall accrue, be credited or be payable on any amounts that are credited to a Participant’s Account under this Plan other than as specified in Article V, Section 5.2. 
  

	11.5.  	Facility of Payment 

 When a Participant entitled to
benefits under the Plan is under a legal disability, or, in the Plan Administrator’s opinion, is in any way incapacitated so as to be unable to manage their financial affairs, the Plan Administrator may direct that the benefits to which such
Participant otherwise would be entitled shall be made to such Participant’s legal representative, or to such other person or persons as the Plan Administrator may direct the application of the benefits for the benefit of such Participant. Any
payment made in accordance with such provisions of this Article XI, Section 11.5 shall be a full and complete discharge of any liability for such payment. 
  

	11.6.  	Controlling State Law 

 To the extent not superseded
by the laws of the United States, the laws of the State of Ohio shall be controlling in all matters relating to the Plan. 
  

 - 10 - 

	11.7.  	Severability 

 In case any provisions of the Plan
shall be held illegal or invalid for any reason, such illegality or invalidity shall not affect the remaining provisions of the Plan, and the Plan shall be construed and enforced as if such illegal and invalid provisions had never been set forth in
the Plan. 
  

	11.8.  	Statutory References 

 All references to the Code
and ERISA include reference to any comparable or succeeding provisions of any legislation, which amends, supplements or replaces such section or subsection. 
  

	11.9.  	Headings 

 Section headings and titles are for
reference only. In the event of a conflict between a title and the content of a section, the content of the section shall control.
