This Separation Agreement (“Agreement”) is entered into by and between Lance W.
Robertson (hereinafter “Robertson”) and Marathon Oil Corporation (hereinafter

herein as “the Parties.”
WHEREAS, the Parties mutually desire to resolve all of their disputes and
potential disputes.
NOW THEREFORE, in consideration of the foregoing, and of the promises and mutual
covenants herein contained, the Parties agree as follows:
1.SEPARATION PAYMENT - In consideration of Robertson’s agreement to all of the
terms, conditions and promises in this Agreement, Marathon agrees to pay to
Robertson the total gross amount of ONE MILLION DOLLARS AND NO CENTS
($1,000,000.00), less all applicable deductions and withholdings, and inclusive
of any and all costs and attorneys’ fees incurred (the “Separation Payment”).
The Separation Payment shall be paid through payroll and reported as wage income
to the Internal Revenue Service on IRS Form W-2. Marathon agrees to deliver the
Separation Payment to Robertson within 15 days following the delivery to
Marathon of this Agreement, executed with Robertson’s original signature and the
date of execution.
2.TAX LIABILITY - Robertson agrees that he shall be liable for the payment of
all federal, state and local taxes which may be due as the result of the
consideration received in the Separation Payment described above. Robertson
understands that Marathon makes no representations regarding tax treatment of
the Separation Payment, and Robertson agrees fully to defend, indemnify and hold
Marathon, and each of its parents, subsidiaries, divisions, affiliates and
operating companies, and the respective officers, directors, employees, agents
and affiliates of each of them, harmless from any liability for payment of the
taxes, penalties, withholding obligations and interest that he owes on the
consideration he receives and that a government agency requests that Marathon
pay, and to cooperate with Marathon with respect to any tax issues related to
the compensation payable under this Agreement.
3.NO LAWSUIT - Robertson represents that he is not a party in any pending
administrative charge, lawsuit, civil action or claim of any kind against
Marathon or any of its parents, subsidiaries, divisions, affiliates or operating
companies, or the respective trustees, directors, officers, shareholders,
employees, agents, attorneys, or insurers of each of them.
4.TERMINATION OF OFFICER AND DIRECTOR APPOINTMENTS - Robertson represents and
agrees that his employment with Marathon has ended, and further agrees that
effective August 19, 2016, he resigned and ceased to serve as an officer or

continuation coverage under Marathon’s group health plans.
6.SUFFICIENCY OF CONSIDERATION - Robertson understands and agrees that the
