Pursuant to this Award Agreement, MARATHON PETROLEUM CORPORATION (the “Corporation”) hereby grants to [NAME] (the “Optionee”), an employee of the Corporation or a Subsidiary, on [DATE] (the “Grant Date”), a right (the “Option”) to purchase from the Corporation [NUMBER] shares of Common Stock of the Corporation at a grant price of $[PRICE] per share (the “Grant Price”), pursuant to the Marathon Petroleum Corporation 2012 Incentive Compensation Plan (the “Plan”), with such number of shares and such price per share being subject to adjustment as provided in the Plan, and further subject to the following terms and conditions:

1. Relationship to the Plan. This Option 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 Optionee also include the heirs or other legal representatives of the Optionee.

(i) one-third of the Option Shares shall become exercisable on the first anniversary of the Grant Date;

(ii) an additional one-third of the Option Shares shall become exercisable on the second anniversary of the Grant Date; and

(iii) the remaining one-third of the Option Shares shall become exercisable on the third anniversary of the Grant Date;

provided, however, that the Optionee must be in continuous Employment from the Grant Date through the date of exercisability of each installment in order for the Option to become exercisable with respect to additional shares of Common Stock on such date. If the Employment of the Optionee is terminated for any reason other than death or Retirement, any Option Shares that are not exercisable as of the date of such termination of Employment shall be forfeited to the Corporation.

(ii) termination of the Optionee’s Employment due to Retirement; or

(iii) a Participant’s Qualified Termination as defined under the Marathon Petroleum Corporation Amended and Restated Executive Change in Control Severance Benefits Plan, provided that as of such Qualified Termination the Optionee had been in continuous Employment since the Grant Date.

3. Expiration of Option.

(a) Expiration of Option Period. The Option Period shall expire on the tenth anniversary of the Grant Date.

(b) Termination of Employment Due to Death or Retirement. If Employment of the Optionee is terminated due to death or Retirement, the Option shall expire upon the earlier of (i) five years following the date of termination of Employment or (ii) expiration of the Option Period. The death of the Optionee following Retirement but prior to the expiration of the Option shall have no effect on the expiration of the Option.

(c) Termination of Employment by the Corporation for Cause or Due to Resignation. If Employment of the Optionee is terminated by the Corporation or any of its Subsidiaries for Cause or due to voluntary resignation by the Optionee, the Option shall expire upon the termination of Employment.

(d) Termination of Employment by the Corporation Other Than For Cause. If Employment of the Optionee is terminated by the Corporation or any of its affiliates for any reason other than Cause, the Option shall expire upon the earlier of (i) ninety (90) days following the date of termination of Employment or (ii) expiration of the Option Period.

(e) Termination of Employment Following a Qualified Termination. If Employment of the Optionee is terminated in a Qualified Termination, the Option shall remain exercisable throughout the Option Period.

Notwithstanding anything herein to the contrary, in the event the Committee, the Chief Executive Officer, or an authorized officer determines that the Optionee has accepted or intends to accept employment with a competitor of any business unit of the Corporation, the Committee, the Chief Executive Officer, or the authorized officer may cancel the Option by written notice to the Optionee.

5. Forfeiture or Repayment Resulting from Forfeiture Event.

(a) Forfeiture of Unexercised Option. If a Forfeiture Event (as defined herein) occurs during the Optionee’s Employment or within two years following Optionee’s termination of Employment, the Committee may, but is not obligated to, cause the Option granted under this Award Agreement to be forfeited with respect to some or all shares of Common Stock subject to the Option.

(b) Repayment of Spread on Exercised Option. If a Forfeiture Event occurs during the Optionee’s Employment or within two years following Optionee’s termination of Employment, the Committee may, but is not

obligated to, require the Optionee to pay to the Corporation an amount up to (but not in excess of) the difference between the Grant Price and market price of the Option on the date of exercise with respect to any shares for which the Option has been exercised (the “Forfeited Spread Amount”). Any Forfeited Spread Amount shall be paid by the Participant within sixty (60) days of receipt from the Corporation of written notice requiring payment of such Forfeited Spread Amount.

(c) Application of Forfeiture Provisions. This Paragraph 5 shall apply notwithstanding any provision of this Award Agreement to the contrary and is meant to provide the Corporation with rights in addition to any other remedy which may exist in law or in equity. This Paragraph 5 shall not apply to the Optionee following the effective time of a Change in Control.

(d) Notwithstanding the foregoing or any other provision of this Award Agreement to the contrary, the Participant agrees that the Corporation may also require that the Participant repay to the Corporation any compensation paid to the Participant under this Award Agreement, 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.

6. Exercise of Option. Subject to the limitations set forth herein and in the Plan, this Option may be exercised in whole or in part by providing notice to the Committee or its designated representative of the number of Option Shares to be exercised. Such notice shall be accompanied by payment of the Grant Price of such Option Shares in cash or, at the election of the Optionee, in shares of Common Stock or any combination thereof. For purposes of determining the amount, if any, of the purchase price satisfied by payment in Common Stock, such Common Stock shall be valued at its Fair Market Value on the date of exercise. Upon receipt of the purchase price, the Corporation or its designated representative shall issue or cause to be issued to the Optionee a number of shares of Common Stock equal to the number of Option Shares then exercised.

7. Taxes. The Corporation or its designated representative shall have the right to withhold applicable taxes from the shares of Common Stock otherwise payable to the Optionee upon exercise of the Option or from compensation otherwise payable to the Optionee at the time of exercise pursuant to the applicable provisions of the Plan.

8. Shareholder Rights. The Optionee shall have no rights of a shareholder with respect to the Option Shares unless and until such time as the Option has been exercised and shares of Common Stock have been issued to the Optionee in conjunction with the exercise of the Option.

9. Nonassignability. During the Optionee’s lifetime, the Option may be exercised only by the Optionee or by the Optionee’s guardian or legal representative. Upon the Optionee’s death, the Option shall be transferred to the Optionee’s estate. Otherwise, the Optionee may not sell, transfer, assign, pledge or otherwise encumber any portion of the Option, and any attempt to sell, transfer, assign, pledge or encumber any portion of the Option shall have no effect.

10. No Employment Guaranteed. Nothing in this Award Agreement shall give the Optionee any rights to (or impose any obligations for) continued Employment by the Corporation or any affiliate thereof or successor thereto, nor shall it give such entities any rights (or impose any obligations) with respect to continued performance of duties by the Optionee.
