MARATHON PETROLEUM CORPORATION PERFORMANCE UNIT AWARD AGREEMENT 2014-2016 PERFORMANCE CYCLE

Pursuant to this Award Agreement and the Marathon Petroleum Corporation 2012 Incentive Compensation Plan (the “Plan”), MARATHON PETROLEUM CORPORATION (the “Corporation”) hereby grants to [NAME] (the “Participant”), an employee of the Corporation or a Subsidiary, on [DATE] (the “Grant Date”), [NUMBER] performance units (“Performance Units”), conditioned upon the Corporation’s TSR ranking relative the Peer Group for the Performance Cycle as established by the Compensation Committee of the Board of Directors of the Corporation (the “Committee”), and as set forth herein. The Performance Units are subject to the following terms and conditions:

1.    Relationship to the Plan. This grant of Performance Units is subject to all of the terms, conditions and provisions of the Plan and administrative interpretations thereunder, if any, that have been adopted by the Committee. Except as otherwise defined in this Award Agreement, capitalized terms shall have the same meanings given to them under the Plan. To the extent that any provision of this Award Agreement conflicts with the express terms of the Plan, the terms of the Plan shall control and, if necessary, the applicable provisions of this Award Agreement shall be hereby deemed amended so as to carry out the purpose and intent of the Plan. References to the Participant also include the heirs or other legal representatives of the Participant.

2.    Determination of Payout Percentage. As soon as practical following the close of the Performance Cycle, the Committee shall determine and certify the TSR Performance Percentile. The final Payout Percentage will be the simple average of the Payout Percentage of the four performance periods, which are as follows:

The Committee shall determine the Payout Percentage for each performance period as follows:

(a)     If the TSR Performance Percentile is below the 25^th percentile, the Payout Percentage for that period shall be zero.

(b)     If the TSR Performance Percentile is at or above the 25^th percentile, the Payout Percentage shall be equal to the TSR Performance Percentile multiplied by 2.

(c)    Notwithstanding anything herein to the contrary, if the TSR calculated for the performance period is negative, then the Payout Percentage for that performance period shall not exceed 100% regardless of the TSR Performance Percentile for the performance period.

(d)    Notwithstanding anything herein to the contrary, the Committee has sole and absolute authority and discretion to reduce the Payout Percentage as it may deem appropriate.

3.    Vesting of Performance Units. Unless the Participant’s right to the Performance Units is previously forfeited or vested in accordance with Paragraphs 4, 5, 6 or 7, following the Committee’s determinations pursuant to Paragraph 2, the Participant shall vest in and be entitled to receive a payment equal to the Payout Value. The Payout Value shall be distributed 75% in cash and 25% in common stock. The number of shares of common stock distributed shall be calculated by dividing 25% of the Payout Value by the closing price as defined in the Plan as of the closing on the date on which the Payout Percentage is determined and certified by the Committee, rounding the shares down to the nearest whole share. The remainder shall be paid in cash. Such payments shall be made as soon as administratively feasible following the Committee’s determination under Paragraph 2 and, in any event, on or before March 15^th following the end of the Performance Cycle. If, in accordance with the Committee’s determination under Paragraph 2, the Payout Value is zero, the Participant shall immediately forfeit any and all rights to the Performance Units. Upon the vesting and/or forfeiture of the Performance Units pursuant to this Paragraph 3 and the making of the related cash payment, if any, the rights of the Participant and the obligations of the Corporation under this Award Agreement shall be satisfied in full.

4.    Termination of Employment. If Participant’s Employment is terminated prior to the close of the Performance Cycle for any reason other than death or Retirement as set forth in Paragraphs 5 and 6 below (or as set forth in Paragraph 7), the Participant’s right to the Performance Units shall be forfeited in its entirety as of such termination, and the rights of the Participant and the obligations of the Corporation under this Award Agreement shall be terminated.

5.    Termination of Employment due to Death. If Participant’s Employment is terminated by reason of death prior to the close of the Performance Cycle, the Participant’s right to receive the Performance Units shall vest in full as of the date of death and the Payout Percentage shall be 100%. The payment equal to the vested value of the Performance Units shall be made in accordance with Paragraph 3 on the first day of the third month following the death of the Participant. Such vesting shall satisfy the rights of the Participant and the obligations of the Corporation under this Award Agreement in full.

6.    Termination of Employment due to Retirement. In the event of the Retirement of the Participant after 50% of the Performance Cycle has elapsed, the Participant’s Performance Units shall be paid-out based on the performance for the Performance Cycle and payable on a pro-rata basis as determined and certified by the Committee at the close of the Performance Cycle as described below. Subject to the negative discretion of the Committee, the Participant will be entitled to receive a payment equal to the product of (i) the pro-rata vesting percentage equal to the days of Participant’s Employment during the Performance Cycle divided by the total days in the Performance Cycle and (ii) the Payout Value. Such payment shall be made as soon as administratively practical following the Committee’s determination under Paragraph 2 and, in any event, on or before March 15^th following the end of the Performance Cycle. If, in accordance with the Committee’s determination under Paragraph 2, the Payout Value is zero, the Participant shall immediately forfeit any and all rights to the Performance Units. Upon the vesting and/or forfeiture of the Performance Units pursuant to this Paragraph 6 and the making of the related cash payment, if any, the rights of the Participant and the obligations of the Corporation under this Award Agreement shall be
