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, Marathon Petroleum Company
LLC, P. O. Box 1, Findlay, Ohio 45839-0001.

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 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.

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.
