Page 24 of 35

Equity Awards to (i) receive shares or common stock issued by Marathon Oil or Marathon Petroleum upon the vesting of an Equity Award other than options or (ii) direct that shares of common stock be sold upon vesting of an Equity Award may be subject to delays or limitations for administrative reasons during such blackout periods.

Section 13.2 Treatment of Outstanding MRO Unvested Options.

(a) All Holders Other than MPC Employees and Speedway Employees. Each MRO Unvested Option outstanding under the MRO Stock Plans at the Effective Time which is held by any Person other than an MPC Employee or a Speedway Employee shall remain an option to purchase Marathon Oil common stock issued under the applicable MRO Stock Plan (each such option, a “Remaining MRO Unvested Option”). Except as provided in this Section 13.2(a), each Remaining MRO Unvested Option shall be subject to the same terms and conditions after the Effective Time as the terms and conditions applicable to the corresponding MRO Unvested Option immediately prior to the Effective Time. The exercise price and number of shares subject to each Remaining MRO Unvested Option shall be adjusted by action of the Board of Directors or Marathon Oil under the applicable MRO Stock Plan as follows: (i) the per-share exercise price of each such Remaining MRO Unvested Option shall be equal to the product of (x) the per-share exercise price of the corresponding MRO Unvested Option immediately prior to the Effective Time and (y) the MRO Price Ratio, rounded up or down to the nearest whole cent, with one-half cents being rounded up (the “MRO Adjusted Exercise Price”) and (ii) the number of shares of Marathon Oil common stock subject to each such Remaining MRO Unvested Option shall be equal to the product of (x) the number of shares of Marathon Oil common stock subject to the corresponding MRO Unvested Option immediately prior to the Effective Time and (y) the quotient obtained by dividing (A) the excess of the MRO Pre-Distribution Stock Value over the original exercise price of such MRO Unvested Option by (B) the excess of the MRO Post-Distribution Stock Value over the MRO Adjusted Exercise Price, with any fractional share rounded down to the nearest whole share.

(b) MPC Employees and Speedway Employees. Each MRO Unvested Option outstanding under the MRO Stock Plans which is held by an MPC Employee or Speedway Employee at the Effective Time shall be converted as of the Effective Time into an option to purchase shares of Marathon Petroleum common stock (each such option, an “MPC Unvested Option”) pursuant to the terms of the MPC Incentive Compensation Plan subject to terms and conditions after the Effective Time that are substantially similar to the terms and conditions applicable to the corresponding MRO Unvested Option immediately prior to the Effective Time, except as provided in this Section 13.2(b). The exercise price and number of shares subject to such MPC Unvested Option shall be determined as follows: (i) the per-share exercise price of each such MPC Unvested Option shall be equal to the product of (x) the per-share exercise price of the corresponding MRO Unvested Option immediately prior to the Effective Time and (y) the MPC Price Ratio, rounded up or down to the nearest whole cent, with one-half cents being rounded up (the “MPC Adjusted Exercise Price”) and (ii) the number of shares of Marathon Petroleum common stock subject to each such MPC Unvested Option shall be equal to the product of (x) the number of shares of Marathon Oil common stock subject to the corresponding MRO Unvested Option immediately prior to the Effective Time and (y) the quotient obtained by dividing (A) the excess of the MRO Pre-Distribution Stock Value over the original exercise price of such MRO Unvested Option by (B) the excess of the MPC Stock Value over the MPC Adjusted Exercise Price, with any fractional share rounded down to the nearest whole share.

(i) Each MRO Unvested Option held by a Delayed Transfer Employee who is an MRO Employee shall be adjusted under Section 13.2(a) on the same basis as any other MRO Unvested Option. Each MRO Unvested Option held by a Delayed Transfer Employee who is an

Page 25 of 35

MPC Employee shall be adjusted under Section 13.2(b) on the same basis as any other MRO Unvested Option held by other MPC Employees.

The exercise price and number of shares subject to such Delayed Transfer MRO Option shall be determined as follows: (A) the per-share exercise price of each such Delayed Transfer MRO Option shall be equal to the product of (x) the per-share exercise price of the corresponding MPC Unvested Option immediately prior to such Delayed Transfer Employee’s Transfer Date and (y) the MRO Delayed Price Ratio, rounded up or down to the nearest whole cent with one-half cents being rounded up and (B) the number of shares of Marathon Oil common stock subject to each such Delayed Transfer MRO Option shall be equal to the product of (x) the number of shares of Marathon Petroleum common stock subject to the corresponding MPC Unvested Option immediately prior to such Delayed Transfer Employee’s Transfer Date and (y) the quotient obtained by dividing (I) the excess of the mean average of the high and low NYSE consolidated transactions system trading prices of Marathon Petroleum common stock on the last Trading Day on the NYSE immediately before such Delayed Transfer Employee’s Transfer Date over the exercise price of the MPC Unvested Option by (II)

Page 26 of 35

the excess of the mean average of the high and low NYSE consolidated transactions system trading prices of Marathon Oil common stock on the last Trading Day on the NYSE immediately before such Delayed Transfer Employee’s Transfer Date over the exercise price for the Delayed Transfer MRO Option, as determined under clause (A) of this Section 13.2(c)(iii), with fractional shares rounded down to the nearest whole share.

The per-share exercise price of each such MPC Vested Option shall be the MPC Adjusted Exercise Price, and the number of shares of Marathon Petroleum common stock subject to each such MPC Vested Option shall be equal to one half the number of shares subject to the corresponding Remaining MRO Vested Option, with fractional shares rounded down to the nearest whole share.

(b) Any MRO Vested Option that is held by an MRO Employee to whom MPC common stock registered on Form S-8 cannot be issued shall be converted as provided in Section 13.2(a), rather than as provided in this Section 13.3. Any MRO Vested Option that is held by an MPC Employee to whom MRO common stock registered on Form S-8 cannot be issued shall be converted as provided in Section 13.2(b), rather than as provided in this Section 13.3.
