Exhibit 10(j)

                                USX CORPORATION
                          DEFERRED COMPENSATION PLAN
                          FOR NON-EMPLOYEE DIRECTORS
                        (Amended as of January 1, 1998)

1.  Purpose

     The USX Corporation Deferred Compensation Plan for Non-Employee Directors
is intended to enable the Corporation to attract and retain non-employee
Directors and to enhance the long-term mutuality of interest between such
Directors and shareholders of the Corporation.

2.  Definitions

     The following definitions apply to this Plan and to the Deferral Election
Forms:

     (a)  Beneficiary or Beneficiaries means a person or persons or other entity
          designated on a Beneficiary Designation Form by a Participant as
          allowed in subsection 8(c) of this Plan to receive Deferred Benefit
          payments. If there is no valid designation by the Participant, or if
          the designated Beneficiary or Beneficiaries fail to survive the
          Participant or otherwise fail to take the Benefit, the Participant's
          Beneficiary is the Participant's surviving spouse or, if there is no
          surviving spouse, the Participant's estate.

     (b)  Beneficiary Designation Form means a form acceptable to the Committee
          or its designee and used by a Participant according to this Plan to
          name his/her Beneficiary or Beneficiaries.

     (c)  Board means the board of directors of USX Corporation.

     (d)  Committee means the Organization and Corporate Governance Committee
          of the Board.

     (e)  Common Stock means the common stock of the Corporation.

     (f)  Common Stock Unit shall have the meaning assigned to it in Section
          7(a).

     (g)  Corporation means USX Corporation.

     (h)  Deferral Election Form means a document governed by the provisions of
          section 4 of this Plan, including the portion that is the Distribution
          Election Form and the related Beneficiary Designation Form.

     (i)  Deferral Year means a calendar year for which a Participant has a
          Deferred Benefit.

     (j)  Deferred Benefit means either a Deferred Cash Benefit or a Deferred
          Stock Benefit under the Plan.


     (k)  Deferred Cash Account means that bookkeeping record established for
          each Participant who elects a Deferred Cash Benefit under this Plan.
          A Deferred Cash Account is established only for purposes of measuring
          a Deferred Cash Benefit and not to segregate assets or to identify
          assets that may or must be used to satisfy a Deferred Cash Benefit. A
          Deferred Cash Account will be credited with that portion of the
          Participant's Retainer Fee deferred as a Deferred Cash Benefit
          according to a Deferral Election Form and according to section 6 of
          this Plan. A Deferred Cash Account will be credited periodically with
          amounts as provided under section 6(b) of this Plan.

     (l)  Deferred Cash Benefit means the Deferred Benefit elected by a
          Participant under section 4 that results in payments governed by
          sections 6 and 8.

     (m)  Deferred Stock Account means that bookkeeping record established for
          each Participant to reflect the status of his/her Deferred Stock
          Benefits under this Plan. A Deferred Stock Account is established only
          for purposes of measuring a Deferred Stock Benefit and not to
          segregate assets or to identify assets that may or must be used to
          satisfy a Deferred Stock Benefit. A Deferred Stock Account will be
          credited with that portion of the Participant's Retainer Fee deferred
          as a Deferred Stock Benefit according to a Deferral Election Form and
          according to sections 3 and 7 of this Plan. A Deferred Stock Account
          will be credited periodically with amounts determined by the Committee
          under subsection 7(b) of this Plan.

     (n)  Deferred Stock Benefit means the Deferred Benefit that results in
          distributions governed by sections 7 and 8.

     (o)  Directors means those duly named members of the Board.

     (p)  Distribution Election Form means that part of a Deferral Election
          Form used by a Participant according to this Plan to establish the
          post-Termination duration of deferral of a Deferred Cash Benefit or a
          Deferred Stock Benefit and the frequency of payments of any Deferred
          Cash Benefit. If a Deferred Benefit has no Distribution Election Form
          that is operative according to section 4, distribution of that
          Deferred Benefit is governed by section 8.

     (q)  Election Date means the date established by this Plan as the date
          before which a Participant must submit a valid Deferral Election Form
          to the Committee. For each Deferral Year, the Election Date is
          December 31 of the preceding calendar year or, in the case of an
          individual who becomes a Participant during a Deferral Year, the date
          that he/she becomes a Participant. Despite the two preceding
          sentences, the Committee may set an earlier date as the Election Date
          for any Deferral Year.

     (r)  Participant means a Director who is not simultaneously an employee of
          the Corporation.

     (s)  Plan means the USX Corporation Deferred Compensation Plan for Non-
          Employee Directors.

     (t)  Retainer Fee means that portion of a Participant's compensation that
          is fixed and paid without regard to his/her attendance at meetings.

     (u)  Terminate, Terminating, or Termination, with respect to a Participant,
          means cessation of his/her relationship with the Corporation as a
          Director whether by retirement, death, disability or severance for any
          other reason.

                                      -2-


3.  Minimum Stock-Based Compensation

     Each Person who becomes a Participant after October 29, 1996 shall receive
at least 50 percent of his/her annual Retainer Fee in the form of Common Stock
Units.

4.  Deferral Election

     A deferral election is valid when a Deferral Election Form is completed,
signed by the Participant, and received by the Committee or its designee.
Deferral elections are governed by the provisions of this section.

     (a)  A Participant may elect a Deferred Benefit for any Deferral Year if
          he/she is a Participant at the beginning of that Deferral Year or
          becomes a Participant during the Deferral Year.

     (b)  Before each Deferral Year's Election Date, each Participant will be
          provided with a Deferral Election Form. Subject to Section 3, a
          Participant may elect on or before the Election Date to defer until
          after Termination the receipt of all or part of his/her Retainer Fee
          for the Deferral Year in the form of a Deferred Stock Benefit or a
          Deferred Cash Benefit.

     (c)  A Participant may not elect to convert a Deferred Cash Benefit to a
          Deferred Stock Benefit or to convert a Deferred Stock Benefit to a
          Deferred Cash Benefit.

     (d)  Each Distribution Election Form is part of the Deferral Election Form
          on which it appears or to which it states that it is related. The
          Committee may allow a Participant to file one Distribution Election
          Form for all of his/her Deferred Cash Benefits and one for all of
          his/her Deferred Stock Benefits. The provisions of subsection 2(p)
          apply to any Deferred Benefit under this Plan if there is no operative
          Distribution Election Form for that Deferred Benefit.

     (e)  If it does so before the last business day of the Deferral Year, the
          Committee may reject any Deferral Election Form or any Distribution
          Election Form or both, and the Committee is not required to state a
          reason for any rejection. The Committee may modify any Distribution
          Election Form at any time to the extent necessary to comply with any
          laws or regulations. However, the Committee's rejection of any
          Deferral Election Form or any Distribution Election Form or the
          Committee's modification of any Distribution Election Form must be
          based upon action taken without regard to any vote of the Participant
          whose Deferral Election Form or Distribution Election Form is under
          consideration, and the Committee's rejections must be made on a
          uniform basis with respect to similarly situated Participants. If the
          Committee rejects a Deferral Election Form, the Participant must be
          paid the amounts he/she would then have been entitled to receive if
          he/she had not submitted the rejected Deferral Election Form.

     (f)  A Participant may not revoke a Deferral Election Form or a
          Distribution Election Form after the Deferral Year begins. Any
          revocation before the beginning of the Deferral Year is the same as a
          failure to submit a Deferral Election Form or a Distribution Election
          Form. Any writing signed by a Participant expressing an intention to
          revoke his/her Deferral Election Form or a related Distribution
          Election Form and delivered to the Committee or its designee before
          the close of business on the relevant Election Date is a revocation.

                                      -3-


5.  Effect of No Election

     A Participant who has not submitted a valid Deferral Election Form to the
Committee or its designee on or before the relevant Election Date may not defer
any part of the cash portion of his/her Retainer Fee for the Deferral Year under
this Plan. In the case of a person who becomes a Participant after October 29,
1996 and who does not submit a valid Deferral Election Form on or before the
relevant Election Date, fifty percent of such Participant's Retainer Fee will
become a Deferred Stock Benefit pursuant to section 4 of this Plan. The Deferred
Benefit of a Participant who submits a valid Deferral Election Form but fails to
submit a valid Distribution Election Form for that Deferred Benefit before the
relevant Election Date or who otherwise has no valid Distribution Election Form
for that Deferred Benefit is governed by section 2(p).

6.  Deferred Cash Benefits

     (a)  Deferred Cash Benefits will be set up in a Deferred Cash Account for
          each Participant and credited with investment returns as provided in
          section 6(b). Deferred Cash Benefits are credited to the applicable
          Participant's Deferred Cash Account as of the day they would have been
          paid but for the deferral.

     (b)  A Participant may select one or more investment options approved by
          the Committee for his/her Deferred Cash Benefits. Amounts will be
          credited to Deferred Cash Accounts to reflect the returns on such
          investment options at periods determined by the Committee.

7.  Deferred Stock Benefits

     (a)  Deferred Stock Benefits will consist of Common Stock Units and will be
          set up in a Deferred Stock Account for each Participant. "Common Stock
          Unit" shall mean a book-entry unit equal in value to a share of USX-
          Marathon Group Common Stock ("Marathon Stock") or USX-U.S. Steel Group
          Common Stock ("Steel Stock"), as the case may be. Common Stock Units
          will be credited as a combination of Marathon Stock and Steel Stock in
          the same ratio as the ratio that the outstanding shares of each class,
          on a fully diluted basis, bear to each other on the last trading day
          of the preceding calendar year. Each Common Stock Unit will increase
          or decrease in value by the same amount and with the same frequency as
          the fair market value of a share of the corresponding class of Common
          Stock. Each Deferred Stock Account will be credited on January 15th of
          each year (or, if such day is not a business day, on the next
          succeeding business day) with a quantity of Common Stock Units
          determined in accordance with this section.

     (b)  Each Deferred Stock Account will be credited each calendar quarter, on
          the date on which dividends are reinvested under the Corporation's
          dividend reinvestment and stock purchase plans (the "Investment
          Date"), with additional Common Stock Units, including fractional
          units, in a quantity equal to the quotient of the dividends payable on
          the quantity of shares in such account divided by the Stock Purchase
          Price. "Stock Purchase Price" means the price, computed to three
          decimal places, obtained by averaging the daily high and low sales
          prices of the relevant class of common stock on the NYSE for the
          twelve days immediately preceding the Investment Date on which shares
          of the relevant class of common stock are reported on the NYSE.

                                      -4-


     (c)  If a trust is established under section 9(b), an electing Participant
          may advise the trustee under the governing trust agreement as to the
          voting of shares of the Common Stock allocated to that Participant's
          separate account under the trust according to this subsection and
          provisions of the governing trust agreement. Before each annual or
          special meeting of the Corporation's shareholders, the trustee under
          the governing trust agreement must furnish each Participant with a
          copy of the proxy solicitation and other relevant material for the
          meeting as furnished to the trustee by the Corporation, and a form
          addressed to the trustee requesting the Participant's confidential
          advice as to the voting of shares of the Common Stock allocated to
          his/her account as of the valuation date established under the
          governing trust agreement preceding the record date.

8.  Distributions

     (a)  According to a Participant's Distribution Election Form, but subject
          to section 4(e), a Deferred Cash Benefit must be distributed in cash.
          Subject to section 4(e), a Deferred Stock Benefit will be distributed
          in shares of Common Stock corresponding to, and equal to the number
          of, the Common Stock Units credited to the Participant's Deferred
          Stock Account. However, cash must be paid in lieu of fractional shares
          of the Common Stock otherwise distributable.

     (b)  Deferred Cash Benefits will be paid in a lump sum unless the
          Participant's Distribution Election Form specifies payment of a
          Deferred Cash Benefit in installment payments over ten years. For a
          Deferred Cash Benefit payable in installments, investment returns
          under section 6(b) will continue to accrue on the unpaid balance of a
          Deferred Cash Account. Any lump-sum cash payment will be paid or
          installment payments will begin to be paid or delivery of Common Stock
          will be made no later than five business days after the Participant's
          Termination, unless a later post-Termination date is specified in a
          Participant's Distribution Election Form.

     (c)  Deferred Benefits may not be assigned by a Participant or Beneficiary.
          A Participant may use a Beneficiary Designation Form to designate one
          or more Beneficiaries for all of his/her Deferred Benefits; such
          designations are revocable. Each Beneficiary will receive his/her
          portion of the Participant's Deferred Cash Account and Deferred Stock
          Account on February 15 of the year following the Participant's death
          unless the Beneficiary's request for a different distribution schedule
          is received before distributions begin and is approved at the
          Committee's sole discretion. The Committee may require that multiple
          Beneficiaries agree upon a single distribution method.

                                      -5-


     (d)  Upon the occurrence of a Change in Control resulting in a
          Participant's Termination, the Corporation shall pay such Participant,
          on the fifth day following such Termination, cash in an aggregate
          amount equal to the value of such Participant's Deferred Cash Account
          and Deferred Stock Account on the date of the Change in Control, as
          determined using the higher of the closing prices of the Common Stock
          on the New York Stock Exchange on such date or the highest per-share
          price actually paid in connection with such Change in Control. For
          purposes of this Plan, "Change in Control" shall mean a change in
          control of a nature that would be required to be reported in response
          to Item 6(e) of Schedule 14A of Regulation 14A promulgated under the
          Securities Exchange Act of 1934, as amended (the "Exchange Act"),
          whether or not the Corporation is then subject to such reporting
          requirement; provided, that, without limitation, such a change in
          control shall be deemed to have occurred if

               (A)  any person (as defined in Sections 13(d) and 14(d) of the
                    Exchange Act) (a "Person") is or becomes the "beneficial
                    owner" (as defined in Rule 13d-3 under the Exchange Act),
                    directly or indirectly, of securities of the Corporation
                    representing twenty percent (20%) or more of the combined
                    voting power of the Corporation's then outstanding voting
                    securities; provided, however, that for purposes of this
                    Agreement the term "Person" shall not include (i) the
                    Corporation or any of its subsidiaries, (ii) a trustee or
                    other fiduciary holding securities under an employee benefit
                    plan of the Corporation or any of its subsidiaries, (iii) an
                    underwriter temporarily holding securities pursuant to an
                    offering of such securities, or (iv) a corporation owned,
                    directly or indirectly, by the stockholders of the
                    Corporation in substantially the same proportions as their
                    ownership of stock of the Corporation; or

               (B)  the following individuals cease for any reason to constitute
                    a majority of the number of directors then serving:
                    individuals who, on the date hereof, constitute the Board
                    and any new director (other than a director whose initial
                    assumption of office is in connection with an actual or
                    threatened election contest including but not limited to a
                    consent solicitation, relating to the election of directors
                    of the Corporation) whose appointment or election by the
                    Board or nomination for election by the Corporation's
                    stockholders was approved by a vote of at least two-thirds
                    (2/3) of the directors then still in office who either were
                    directors on the date hereof or whose appointment, election
                    or nomination for election was previously so approved; or

               (C)  there is consummated a merger or consolidation of the
                    Corporation or a subsidiary thereof with any other
                    corporation, other than a merger or consolidation which
                    would result in the holders of the voting securities of the
                    Corporation outstanding immediately prior thereto holding
                    securities which represent immediately after such merger or
                    consolidation at least 50% of the combined voting power of
                    the voting securities of the entity surviving the merger or
                    consolidation (or the parent of such surviving entity) or
                    the shareholders of the Corporation approve a plan of
                    complete liquidation of the Corporation, or there is
                    consummated the sale or other disposition of all or
                    substantially all of the Corporation's assets.

                                      -6-


9.  Corporation's Obligation

     (a)  The Plan is unfunded. A Deferred Benefit is at all times solely a
          contractual obligation of the Corporation. A Participant and his/her
          Beneficiaries have no right, title or interest in the Deferred
          Benefits or any claim against them. Except according to section 9(b),
          the Corporation will not segregate any funds or assets for Deferred
          Benefits nor issue any notes or security for the payment of any
          Deferred Benefit.

     (b)  The Corporation may establish a grantor trust and transfer to that
          trust shares of the Corporation's common stock or other assets. The
          governing trust agreement must require a separate account to be
          established for each electing Participant. The governing trust
          agreement must also require that all Corporation assets held in trust
          remain at all times subject to the Corporation's judgment creditors.

10. Control by Participant

     A Participant has no control over Deferred Benefits except according to
his/her Deferral Election Forms, Distribution Election Forms, and Beneficiary
Designation Form.

11. Claims Against Participant's Deferred Benefits

     A Deferred Cash Account and Deferred Stock Account relating to a
Participant under this Plan are not subject in any manner to anticipation,
alienation, sale, transfer, assignment, pledge, encumbrance, or charge, and any
attempt to do so is void. A Deferred Benefit is not subject to attachment or
legal process for a Participant's debts or other obligations. Nothing contained
in this Plan gives any Participant any interest, lien or claim against any
specific asset of the Company. A Participant or his/her beneficiary has no
rights other than as a general creditor.

12. Amendment or Termination

     This Plan may be altered, amended, suspended, or terminated at any time by
the Board.

13. Notices

     Notices and elections under this Plan must be in writing. A notice or
election is deemed delivered if it is delivered personally or if it is mailed by
registered or certified mail to the person at his/her last known business
address.

14. Waiver

     The waiver of a breach of any provision in this Plan does not operate as
and may not be construed as a waiver of any later breach.

15. Construction

     This Plan is created, adopted, maintained and governed according to the
laws of the state of Delaware. Headings and captions are only for convenience;
they do not have substantive meaning. If a provision of this Plan is not valid
or not enforceable, the validity or enforceability of any other provision is not
affected. Use of one gender includes all, and the singular and plural include
each other.

16. Effective Date

     This Plan shall be effective January 1, 1997.

                                      -7-
