Participants and Target Funding

Prior to March 30^th of the Performance Period, or at such later time as may be permitted by applicable provisions of the Code, the Committee shall establish in writing (1) the Eligible Employees who will be Participants in the Program, (2) each Participant's target funding percentage for such Performance Period or the formula for determining each Participant's Award and (3) the applicable performance objective or objectives for such Performance Period which will be based on the Qualifying Performance Criteria. Each Participant’s funding range will have a threshold of 0% and a maximum of two times (2X) their target funding percentage.

Threshold funding for individual metrics is one-half (.5X) of target and the maximum that can be funded is two times (2X) target. Percentages may be rounded. No metric will fund when results are below threshold performance.

Funding ranges for Participants shall be based on grade:

Participant Classification	Target	Award Range
Above Grade 18	Per the Committee	Per the Committee
Grade 18	50%	0% - 100%
Grade 17	40%	0% - 80%
Grade 16	35%	0% - 70%
Grade 15	30%	0% - 60%
Grade 14	25%	0% - 50%
Grade 13	20%	0% - 40%
Grade 12	15%	0% - 30%
Grade 11	12%	0% - 24%
Grade 10	12%	0% - 24%
Grade 9	10%	0% - 20%
Grade 8	10%	0% - 20%
Grade 7	7%	0% - 14%
Grade 6	7%	0% - 14%
Grade 5	7%	0% - 14%
Grade 4	7%	0% - 14%
Grade 3	7%	0% - 14%
Grade 2	7%	0% - 14%
Grade 1	7%	0% - 14%

Performance Metrics

The Committee, or its delegate, will establish metrics (in accordance with the Program), with threshold, target and maximum performance criteria. Once approved, these performance criteria are incorporated into this Program document by reference.

When any final performance metric result falls between threshold and target or between target and maximum performance levels, linear interpolation will be used to determine funding based on actual achievement. For example, if the final result of a metric is halfway between threshold and target performance levels, the funding for that metric would be halfway between the corresponding payout percentages.

Determination of Awards

Final calculated bonus payments are automatically rounded up to the nearest $50 for non-officer employees and to the nearest $1,000 for Officers.

Bonus Pool(s)

The Program for a Performance Period may consist of one or more umbrella performance pools. The Committee shall approve the structure of each such pool (if any) and designate the Participants in the pool, the total amount of the pool, and such Participant's allocable percentage share of such pool prior to March 30 of the Performance Period (or such later time as may be permitted by applicable provisions of the Code). To the extent a pool includes "Covered Employees" within the meaning of Section 162(m) of the Code, the pool shall be operated in compliance with the requirements of Section 162(m), which require that (1) each Participant's percentage share of the pool must be established no later than 90 days after the commencement of the applicable Performance Period, and (2) the exercise of negative discretion with respect to one Participant in the pool may not result in an increase in the amount payable to any Covered Employee who is a Participant in such pool.  Moreover, if the amount payable to each Participant in a pool that includes one or more Covered Employees is stated in terms of a percentage of the pool, the sum of the individual percentages of the pool may not exceed 100 percent.

The performance goals for any performance pools, to the extent they cover or potentially cover Covered Employees, will be based solely on Qualifying Performance Criteria. Satisfaction of these Criteria will enable a Participant to earn 100% of his or her allocated amount under such pools. The Committee may then take into account other criteria (whether or not Qualifying Performance Criteria) and use negative discretion to decrease a Participant's Award, but it may not use other criteria or positive discretion to increase the Award for any Covered Employee.

The same objective goals can be used both to set the amount of each performance pool and to function as the Qualifying Performance Criteria to determine if a bonus (and the amount of the bonus) was earned. The Committee shall establish a minimum threshold for the Qualifying Performance Criteria, below which no bonus will be earned.

Without regard to anything contained within this Program, the Committee reserves the unconditional right to award a payout to any Covered Employee up to the full value of their funding pool allocation without regard to the performance achieved under this operational program.

Individual Funding Vs. Payout

The operation of this Program funds individual payments based on pre-established metrics and subjective metrics as approved by the Committee. The final payout to each Participant is determined based on the assessment of their management considering each Participant’s relative performance to other employees. However, no Participant can be awarded more than their maximum percent as specified on page 6 without approval of the Committee or its delegate.

Hires, Promotions and Transfers

In the case of a newly hired, promoted, or transferred Participant, the Committee may provide for a guaranteed bonus, or a bonus that would exceed the bonus that would otherwise be payable in the Program unless the Participant is a Covered Employee, in which case no guarantees or excess payments would apply.

Participants who change from one eligible position to another during the Performance Period may experience a change to their Program target funding, individual objectives or the formula for determining each Participant’s Award. In this situation, funding shall be based on the associated target level and business unit for the position held by the Participant on the last day of the Performance Period, provided the position held is not temporary.

If a Participant transfers to a position that is not eligible under the Program during the Performance Period, such Participant will be ineligible for any payout under this Program for such Performance Period. Except however, if a Participant transfers to a Speedway position that is not eligible under the Program during the Performance Period, such Participant will remain eligible for an Award based on their Eligible Wages paid while a Participant under the Program.

Temporary Assignments

Eligibility and funding targets for employees who are on a temporary assignment on the last day of the last pay period completed for the Performance Period shall be determined based on their regular assignment.

Exclusions and Adjustments

To the extent consistent with Section 162(m) of the Code, the Committee or its delegate may (A) adjust the actual performance or performance goals (either up or down) and the level of the Performance Award that a Participant may earn under this program if it determines that the occurrence of external changes or other unanticipated business conditions have materially affected the fairness of the goals and / or have unduly influenced the Company’s ability to meet them; including, without limitation, events such as material acquisitions, asset write-downs, litigation, claims, judgments or settlements, force majeure events, unlawful acts committed against the Company or its property (including terrorism), labor disputes, legal mandates, accruals for reorganization and restructuring programs and changes in the capital structure of the Company, the effect of changes in tax law or other such laws or provisions affecting reported results, accruals of any amounts for payment under this Plan or any other compensation arrangement maintained by the Company, or other events not contemplated at the time the goals are set; provided, however, that Performance Awards granted to Covered Employees or Executive Officers shall be adjusted only to the extent permitted under Section 162(m) of the Code. In addition, Performance Goals and Performance Awards shall be calculated without regard to any changes in accounting standards or codifications that may be required by the Financial

Accounting Standards Board or other standards board or the effect of changes in tax law or other such laws or provisions affecting reported results after such Performance Goals are established.

Certification by Committee

Unless otherwise determined by the Committee, no payments shall be made hereunder in respect of any Performance Period unless the Committee shall certify in writing following the end of the Performance Period that the performance objectives applicable to the Performance Period have been satisfied. In all events, no payments hereunder shall be made to any "Covered Employee" (within the meaning of Section 162(m) of the Code) until after satisfaction of the performance criteria has been certified in writing by the Committee.

Separation of Employment

Unless otherwise determined by the Committee and except as may otherwise be provided in a Participant's written agreement with the Company or an Affiliate, if a Participant's employment terminates for any reason prior to payment, such Participant shall not be eligible for an Award under the Program, unless the Participant's employment terminated as a result of death, Severance, or Retirement (prior to July 1 of a Performance Period). Except in the case of death, an Award will be at the Committee's discretion, but any such payment of Award will (i) only be made after the end of the Performance Period (and as close as practicable to the same time as all other Award payments for such Performance Period), and (ii) only be paid to the extent that the performance criteria were achieved.

Any Participant who retires on or after July 1 of a Performance Period is eligible for an Award under this Program, based on their Eligible Wages paid during the Performance Period, at the discretion of the Committee. A Participant is considered to have Retired if the Participant, at the time of separation:

a. has reached the age 50 or more with 10 years of accredited service, and

b. is deemed to be in good standing.

Severance

Severance is defined to include any Participant who separates employment during a Performance Period and who becomes eligible for a termination allowance under the Company’s Termination Allowance Plan. However, any Participant who voluntarily requests termination under the Company’s Termination Allowance Plan is not considered to be an Eligible Employee under this Program.

In addition, Eligible Employees who would have otherwise been eligible for the Marathon Petroleum Termination Allowance Plan, but accepted an offer of employment with:

a. the “buyer” of sold Company assets, or

b. the “new operator” of a jointly-owned facility, or

c. a company that has been contracted to perform services being outsourced.

will remain eligible for consideration of an Award provided the termination date is after June 30^th of the Performance Period.

Death of Participant

If the death of a Participant occurs:

a. during a Performance Period, their eligibility for the Program will end and a payment will be made to the Participant’s estate as soon as practicable following death. Such payment will be based on target performance levels for all metrics and the Participant’s Eligible Wages paid during a Performance Period.

b. after a Performance Period, but before payment for that Performance Period has been made, the full Award otherwise deemed payable under the Program will be made to the Participant’s estate (as close to the time all other Award payments for such Performance Period are made).

Payment of Awards

Following the Performance Period, each Participant's Award for the Performance Period will be determined in accordance with the terms of the Program and the Participant shall be eligible to receive payment of the Award.

The Committee shall determine whether payment of the Award will be in cash, Common Shares, the right to receive Common Shares, Stock Options or other Awards provided for under the Plan; and whether any such payments will be subject to restrictions on transfer, vesting, forfeiture or deferral requirements. Any equity or equity-based Awards shall be granted under the terms and conditions of the Plan.

Change in Control

Unless otherwise determined by the Committee prior to a Change in Control, and except as otherwise may be provided in a Participant’s written agreement with the Company or Affiliate upon a Change in Control, this Program will automatically terminate and all Participants will be vested and entitled to a pro-rated lump sum payment equal to 100% of the Participant’s target multiplied by their Eligible Wages. This payment will be made as soon as administratively practicable following the Change in Control, but in no event later than 45 days from the Change in Control.

No Right to Awards

Except as may be provided for under the Change in Control section of this Program, no Participant or other person shall have any claim or right to be granted an Award under this Program. Neither the establishment of this Program, nor any action taken hereunder, shall be construed as giving any Participant any right to be retained in the employ of the Company, or participate hereunder in the current or succeeding Performance Periods. Nothing contained in this Program shall limit the ability of the Company to make payments or Awards to Participants under any other Program, agreement or arrangement; provided, however, that no payment under any other Program, agreement, or arrangement will be made because of a failure of a Participant to earn an Award hereunder, and no such payment outside of this Program will be in the nature of or in any way related to make-whole payments for what would have been earned or paid hereunder if the performance goals had been met.

Non-Transferability

The rights and benefits of a Participant hereunder are personal to the Participant and, except for any payments that may be made following a Participant's death, shall not be subject to any voluntary or involuntary alienation, assignment, pledge, transfer, encumbrance, attachment, garnishment or other disposition.

No Impact on Benefits

Except as may be required by law or otherwise be specifically stated under any employee benefit plan, policy, or program, no amount payable in respect of any Award shall be treated as compensation for purposes of calculating a Participant's right under any such plan, policy, or program; nor shall any Award be treated as compensation for purposes of termination indemnities or other similar rights, except as may be required by law.

No Constraint on Corporate Actions

Nothing in this Program shall be construed (1) to limit, impair, or otherwise affect the Company's right or power to make adjustments, reclassifications, reorganizations, or changes of its capital or business structure, or to merge or consolidate, or dissolve, liquidate, sell, or transfer all or any part of its business or assets, or (2) to limit the right or power of the Company or any of its Affiliates to take any action which such entity deems to be necessary or appropriate.

Program Administration

The program shall be administered by the Committee, which shall have full authority to:

a. interpret the Program,

b. establish, interpret, amend or revoke rules and regulations relating to the operation of the Program,

c. interpret the Program, to correct any defect, supply any omission or reconcile any inconsistency in the Program,

d. adopt such rules for the administration, interpretation and application of the Program, and

e. make all determination and take all other actions necessary or appropriate for the proper administration of the Program.

The Committee has complete, unilateral discretion with respect to all aspects of the operation, administration, design, features, benefits and Awards under the Program and can change, terminate, or modify Awards, or otherwise change any aspect of the Plan in its discretion prospectively or retroactively, regardless of anything stated in this document. Notwithstanding the above, with respect to a Covered Employee, the Committee cannot (1) grant or change an Award, or the Qualified Performance Criteria thereunder, after the deadline under Code Section 162(m) for setting such Award (generally March 30th of a Performance Period for annual Awards), (2) deem its performance goals satisfied when they have not been met, or (3) use its discretion to increase the amount otherwise payable under any Award.

The Committee may delegate any or all of their authorities hereunder, provided that the Committee shall, in no event, delegate its authority with respect to the compensation of any Participant whose compensation the Board or Committee reasonably believes may become subject to Section 162(m) of the Code. No member of the Committee shall be eligible to participate in the Program.

Taxes

For U.S. Participants, any Award received under the Program is subject to all applicable employment withholding taxes in the year paid. For Participants outside the United States, local country tax regulations will apply.

Deductions

There shall be deducted from all individual payouts any taxes required to be withheld by national, Federal, state provincial or local governments and paid over to such government for the accounts of such Participants.

The Company may also deduct from an individual Award, at its sole discretion, any and all amounts determined by Company management to be owed to the Company by the Participant.

Affiliate Requirements

Prior to the selection of employees of an affiliated company to participate in the Program, the Committee may require the Affiliate to consent to the participation of such employee or employees in the Program and to the charging of such Affiliate with the amount of any Award which may be made to such employee or employees.

Recoupment / Clawback

Officers are subject to recoupment provisions in the Program, in the case of certain forfeiture events. If the Company is required, pursuant to a determination made by the SEC or the Audit Committee of the Board, to prepare a material accounting restatement due to the noncompliance of the Company with any financial reporting requirement under applicable securities laws as a result of misconduct, the Audit Committee of the Board may determine that a forfeiture event has occurred based on an assessment of whether an officer knowingly engaged in misconduct, was grossly negligent with respect to misconduct, knowingly failed or was grossly negligent in failing to prevent misconduct or engaged in fraud, embezzlement, or other similar misconduct materially detrimental to the Company.

Upon the Audit Committee’s determination that forfeiture event has occurred, the Company has the right to request and receive reimbursement of any portion of an officer’s bonus from the Program that would not have been earned or paid had the forfeiture event not have taken place.

These recoupment provisions are in addition to the requirements in Section 304 of the Sarbanes-Oxley Act of 2002 which provide that the CEO and CFO shall reimburse the Company for any bonus or other incentive-based or equity-based compensation as well as any related profits received in the 12-month period prior to the filing of an accounting restatement due to non-compliance with financial reporting requirements as a result of Company misconduct.

Notwithstanding the foregoing or any other provision of this Program to the contrary, the Company may also require that the Participant repay to the Company any compensation paid to the Participant under this Program, as is required by the provisions of the Dodd-Frank Act and the regulations thereunder or any other “clawback” provisions as required by law or by the applicable listing standards of the exchange on which the Corporation’s common stock is listed for trading.

Other Provisions

In all events, whether any cash Award is paid to a Participant will depend on the decision of the Committee (or its delegate, as appropriate). All Awards are subject to the sole discretion of the Committee or its delegate, and nothing in this document (except as may be provided for in the Change in Control provisions) or any other document describing or referring to the Program shall confer any right whatsoever on any person to be considered for any Award.

This document does not purport to be complete and is subject to and governed by actions, rules and regulations of the Committee (or its delegate, as appropriate).

The Program may be changed or discontinued at any time without notice or liability at the sole discretion of the Committee.

Awards shall be subject to and governed by the specific terms and conditions of the Program and the applicable Award.

Nothing contained herein shall require the Company to segregate any monies from its general fund or to create any trusts, or to make any special deposits for amounts payable to any Participant.

The Program is intended to be operated in accordance with the requirements of Section 162(m) of the Code where applicable, and shall be interpreted consistent with that intent.

No member of the Committee, or employee of the Company, shall be liable for any act done, or determination made in good faith, with respect to the administration of this Program. The Company indemnifies and holds harmless to the fullest extend allowed by law such persons individually and collectively, from and against any and all losses resulting from liability to which the Committee, or the members of the Committee, or employee of the Company may be subjected by reason of any act or conduct (except willful misconduct, fraud or gross negligence) in their official capacities in the administration of the Program, including all expenses reasonably incurred in their defense, in case the Company fails to provide such defense.

Any provision of the Program prohibited by law shall be ineffective to the extent of such prohibition without invalidating the remaining provisions.

The terms of this Program document supersede any written or verbal agreements, representations, proposals, or plans with respect to the subject matter hereof; provided, however, that the forgoing shall not act to supersede an existing written agreement between a Participant and the Company that has been approved by the Committee.
