                                              EXECUTION COPY
                    AMENDMENT NO. 1, dated as of
               December 31, 1998 (this "Amendment") to the
               PUT/CALL, REGISTRATION RIGHTS AND STANDSTILL
               AGREEMENT dated as of January 1, 1998 (the
               "Agreement") among MARATHON OIL COMPANY, an
               Ohio corporation, USX CORPORATION, a Delaware
               corporation, ASHLAND INC., a Kentucky
               corporation and MARATHON ASHLAND PETROLEUM
               LLC, a Delaware limited liability company
               (collectively, the "Parties").

          WHEREAS, the Parties have heretofore entered into
the Agreement (capitalized terms used in this Amendment and
not defined herein shall have the meanings given such terms
in the Agreement); and

          WHEREAS, the Parties wish to amend the Agreement
to reflect certain changes to the prices set forth therein.

          NOW, THEREFORE, in consideration of the mutual
agreements herein contained and other good and valuable
consideration, the sufficiency and receipt of which are
hereby acknowledged, the Parties agree as follows:

          Section 1.  Amendments:

          (a)  Section 1.01 of the Agreement is amended to
insert the following definition after the definition of
"Price Index" and prior to the definition of "Private Label
Packaged Motor Oil Business":

          "'Price Reduction' shall have the meaning set
     forth in Section 2.02(b) of the Put/Call, Registration
     Rights and Standstill Agreement."

          (b)  Section 2.02(a) of the Agreement is amended
to read in its entirety as follows:

          "(a)  Amount.  The Special Termination Price shall
     be an amount equal to (i) the product of (x) 100% of
     the Appraised Value of the Company multiplied by
     (y) the Terminating Member's Percentage Interest, less
     (ii) if the Terminating Member is Ashland, the Price
     Reduction."

          (c)  Sections 2.02(b) and 2.02(c) as numbered in
the Agreement are numbered Sections 2.02(c) and 2.02(d)
respectively and a new Section 2.02(b) of the Agreement is
added to read in its entirety as follows:

          "(b) Price Reduction.  Price Reduction means an
     amount equal to the excess of (i) $14,139,519, which is
     the agreed present value at January 1, 1998, of the tax
     cost to Ashland ("Present Value Tax Cost") of
     allocating to it depreciation deductions as shown in
     Chart A in Schedule 2.02(b)(1) ("Chart A
     Depreciation"), as compared to allocating to Ashland
     depreciation deductions as shown in Chart B in
     Schedule 2.02(b)(1) ("Chart B Depreciation"), over
     (ii) the present value at January 1, 1998, of the tax
     cost to Ashland of allocating to it Chart A
     Depreciation as compared to Chart B Depreciation,
     taking into account Ashland's decreased taxable gain or
     increased taxable loss on the sale of all of its
     Membership Interest in the Company when Chart A
     Depreciation as compared to Chart B Depreciation is
     allocated to it ("Present Value Tax Cost on Sale").

          "Chart A Depreciation represents the agreed
     depreciation deductions with respect to property
     contributed by Ashland on the Closing of the Asset
     Transfer and Contribution Agreement allocated to it
     through the depreciable life of such property as set
     forth in Section 6.03 of the LLC Agreement as amended
     and restated as of December 31, 1998.  Chart B
     Depreciation represents the agreed depreciation
     deductions with respect to property contributed by
     Ashland on the Closing of the Asset Transfer and
     Contribution Agreement allocated to it through the
     depreciable life of such property as set forth in
     Sections 6.03, 6.12 and 4.01(c) of such agreement as in
     effect prior to such restatement as if it were in
     effect through such depreciable life, but treating the
     assets comprising the Merrill Lynch Master Lease
     Program as Subleased Property listed on Schedule
     4.01(c) for purposes of Sections 4.01(c) and 6.12.
     Chart A Depreciation and Chart B Depreciation shall not
     be revised to reflect the actual amount of depreciation
     deductions with respect to property contributed by
     Ashland on the Closing of the Asset Transfer and
     Contribution Agreement allocated to Ashland, or to take
     into account the sale or other disposition by the
     Company of any of the property contributed by Ashland
     on the Closing of the Asset Transfer and Contribution
     Agreement.

          "Solely for purposes of determining the Present
     Value Tax Cost and the Present Value Tax Cost on Sale,
     the following factors and assumptions have been and
     will be used: (i) discount rate of 9% per annum,
     (ii) combined Federal/State income tax rate of 39%,
     (iii) the cash flow impact of a reduction in Ashland's
     income taxes for a year as the result of Chart A or
     Chart B Depreciation is realized on the last day of
     that year and (iv) the cash flow impact of Ashland's
     income tax expense or benefit arising from a sale of
     all of its membership interest in the Company is
     incurred or realized on the last day of the year of
     sale.

          "Schedule 2.02(b)(2) reflects, for purposes of
     illustration, the Present Value Tax Cost on Sale if
     Ashland sells all of its 38% membership interest in the
     Company on January 1, 2005.  The Present Value Tax Cost
     on Sale with respect to Ashland's sale of all of its
     interest in the Company at a date different than
     January 1, 2005, shall be computed in the same manner
     as the Present Value Tax Cost on Sale illustrated in
     Schedule 2.02(b)(2).

          "Consistent with the foregoing principle, if
     Ashland sells all or part of its Membership Interest to
     Marathon in a transaction not otherwise described in
     this Agreement, the price paid by or on behalf of
     Marathon for such interest shall be appropriately
     reduced."

          (d)  Attached new Schedules 2.02(b)(1) and
2.02(b)(2) are inserted between Schedule 1.03(d) and
Schedule 14.01(a).

          (e)  Section 3.02(a) of the Agreement is amended
to read in its entirety as follows:

          "(a)  Amount.  The Marathon Call Price shall be an
     amount equal to (i) the product of (x) 115% of the
     Appraised Value of the Company multiplied by
     (y) Ashland's Percentage Interest, less (ii) the Price
     Reduction."

          (f)  Section 4.02(a) of the Agreement is amended
     to read in its entirety as follows:
          "(a)  Amount.  The Ashland Put Price shall be an
     amount equal to the sum of (i) for that portion of the
     Ashland Put Price to be paid to Ashland in Cash or in
     Marathon Debt Securities, an amount equal to the
     product of (1) the excess of (x) the product of (A) 85%
     of the Appraised Value of the Company multiplied by
     (B) Ashland's Percentage Interest over (y) the Price
     Reduction, multiplied by (2) the percentage of the
     Ashland Put Price to be paid to Ashland in Cash and/or
     in Marathon Debt Securities, plus (ii) for that portion
     of the Ashland Put Price to be paid to Ashland in
     Marathon Equity Securities the same as above but
     substituting 90% for 85% in Clause (A) and substituting
     Marathon Equity Securities for Cash and/or Marathon
     Debt Securities in clause (2)."

          Section 2.  Parties in Interest.  This Amendment
shall inure to the benefit of, and be binding upon, the
Parties hereto and their respective successors, legal
representatives and permitted assigns.

          Section 3.  Counterparts.  This Amendment may be
executed in counterparts, each of which shall be deemed an
original, but all of which together shall constitute one and
the same instrument.

          Section 4.  Governing Law.  THIS AMENDMENT SHALL
BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF
THE STATE OF DELAWARE, WITHOUT GIVING EFFECT TO THE
PRINCIPLES OF CONFLICTS OF LAW THEREOF.  ANY RIGHT TO TRIAL
BY JURY WITH RESPECT TO ANY CLAIM OR PROCEEDING RELATED TO
OR ARISING OUT OF THIS AMENDMENT, OR ANY TRANSACTION OR
CONDUCT IN CONNECTION HEREWITH, IS WAIVED.


          IN WITNESS WHEREOF, the parties hereto have caused
this Amendment to be duly executed as of the day and year
first above written.
