           Marathon Oil Corporation Non-Officer Restricted Stock Plan
               (As Amended and Restated Effective January 2, 2002)

1.   Purpose

     The objective of the Marathon Oil Corporation Non-Officer Restricted Stock
     Plan, formerly named the USX Corporation Non-Officer Restricted Stock Plan,
     (the "Plan") is, through the issuance of restricted stock ("Shares"), to
     advance the interests of Marathon Oil Corporation (formerly named USX
     Corporation), its subsidiaries, affiliates and joint ventures (the
     "Corporation") (a) by promoting the retention of outstanding employees, (b)
     by rewarding specific noteworthy achievements on the part of an employee or
     a group of employees, (c) by motivating employees through growth-related
     incentives to achieve long-term goals and (d) by aligning the interests of
     employees with those of the stockholders.

2.   Administration

     The Compensation and Organization Committee of the Marathon Oil Corporation
     Board of Directors (the "Compensation and Organization Committee") shall
     create and authorize pools of specific numbers of Shares to be granted
     under the Plan by the Granting Committee. Authorizations shall be made
     every two years, and no authorization shall exceed 1 percent of the total
     shares of common stock outstanding on December 31 of the preceding year. In
     addition, Shares related to grants that are forfeited or cancelled before
     vesting shall immediately become available for grants, and these Shares, as
     well as any unused portion of the percentage limit of Shares available from
     previous authorizations, shall be carried forward and available for grants
     in succeeding calendar years.

     Except as otherwise set forth herein, the Plan shall be administered by the
     Salary and Benefits Committee of the Corporation (the "Administering
     Committee"). The Administering Committee shall establish its own guidelines
     for general administration of the Plan. Such guidelines shall be subject to
     review by the Law, Tax and Accounting departments. The Administering
     Committee shall have the power to cancel a grant made under the Plan when
     such cancellation is deemed appropriate. The Administering Committee may
     delegate to the Stock Plan Officer (as designated under the Marathon Oil
     Corporation 1990 Stock Plan) its duties under this Plan pursuant to such
     conditions or limitations as the Administering Committee may establish.

     From and after May 28, 2002, the Compensation and Organization Committee
     shall authorize a committee (the "Director Committee") consisting of the
     employee Director(s) of the Marathon Oil Corporation Board of Directors to
     grant awards of specific numbers of Shares to eligible employees. The term
     "Granting Committee" shall refer to the Administrative Committee prior to
     May 28, 2002, and shall refer to the Director Committee from and after May
     28, 2002.





3.   Eligibility for Participation

     Individuals who are employed by one of the following entities and are below
     Salary Grade 19 shall be eligible to receive grants under the Plan:

          Marathon Oil Corporation and its wholly-owned direct and indirect
          subsidiaries, Marathon Oil Company and its wholly-owned direct and
          indirect subsidiaries, Marathon Ashland Petroleum LLC and its
          wholly-owned direct and indirect subsidiaries, Speedway SuperAmerica
          LLC and its wholly-owned direct and indirect subsidiaries, or any
          foreign entity that is wholly-owned, directly or indirectly, by
          Marathon Oil Corporation.

     The Granting Committee shall select from among such eligible employees
     those to whom Shares shall be granted and shall determine the number of
     Shares to be granted to each such grantee.

4.   Grants

     All grants shall be subject to such forfeiture and transfer restriction
     provisions as may be established by the Administering Committee. Grantees
     receiving an award shall have all the rights of a stockholder of the
     Corporation, including the right to vote the Shares and the right to
     receive any cash dividends paid thereon.

5.   Source of Shares

     Shares granted under the Plan may be granted out of authorized and unissued
     shares, treasury shares or open-market purchases.

6.   Vesting

     Shares granted to an employee shall vest as follows: 50 percent of the
     Shares received pursuant to a specific grant shall vest on the second
     anniversary of the grant, the remaining 50 percent shall vest on the fourth
     anniversary of the grant. Each grant shall be subject to the condition that
     the employee's continuous service with the Corporation continues through
     the relevant anniversary date, unless terminated by reason of death.
     Notwithstanding anything herein to the contrary, if the grantee is eligible
     to participate in a change of control plan adopted by his or her employer,
     any provisions of such plan that relate to the vesting of restricted stock
     shall apply to the Shares.

7.   Adjustments

     In the event of any change in the outstanding common stock of the
     Corporation by reason of a stock split, stock dividend, stock combination
     or reclassification, recapitalization or merger, or similar event, the
     Compensation and Organization Committee may appropriately adjust the number
     of Shares covered by a grant and make such other revisions to outstanding
     grants as it deems are equitably required.


                                       2




8.   Tax Withholding

     The Corporation shall have the right to condition the obligation to deliver
     or the vesting of Shares under this Plan upon the employee paying the
     Corporation such amount as it may request to satisfy any liability for
     applicable withholding taxes. Employees may elect to have the Corporation
     withhold Shares to satisfy all or part of their withholding liability in
     the manner and to the extent provided for by the Administering Committee at
     the time of such election.

9.   Amendments

     The Administering Committee shall have the authority to make such
     amendments to any terms and conditions applicable to outstanding grants as
     are consistent with the Plan, provided that, except for adjustments under
     Paragraph 7 hereof, no such action shall modify a grant in a manner adverse
     to the grantee without the grantee's prior consent, except as such
     modification is provided for or contemplated in the terms of the grant. The
     Marathon Oil Corporation Board of Directors shall approve all amendments to
     the Plan.

10.  Awards to Employees on Non-U.S. Payrolls

     The Granting Committee shall have the power to grant awards under the Plan
     in the form of restricted stock units ("Units"), with each Unit
     representing the right to receive one share of the Corporation's common
     stock ("Common Stock"), subject to certain conditions. Grantees receiving
     Units shall have the right to receive cash dividend equivalents equal in
     value to any cash dividends paid on the shares of Common Stock represented
     by the Units but shall have no voting rights with respect to such Units
     prior to the vesting of the Units. Upon the vesting of Units under
     Paragraph 6 hereof, the vested Units shall be cancelled and a number of
     shares of Common Stock equal to the number of vested Units shall be
     registered in the name of the grantee. Thereafter the grantee shall have
     all the rights of a stockholder of the Corporation, including the right to
     vote such shares of Common Stock. Except as otherwise noted in this
     Paragraph 10, Units granted hereunder shall be subject to the provisions of
     Paragraphs 1 through 9 of the Plan; provided however, that the terms and
     conditions of such Units shall be subject to the rules and regulations of
     applicable U.S. and foreign laws (including, but not limited to tax
     withholding, resale restrictions, and transferability), and shall be
     administered at all times in accordance with such applicable laws.

11.  Effective Date

     This amended and restated Plan is effective as of January 2, 2002, and
     supercedes the prior Plan document.
