The Lubrizol Corporation

Wickliffe, Ohio 44092

Dear Dr. Hsu:

        This letter will set forth our amendment (the
"Amendment") to the agreement (the "Agreement") of February 23,
1987, as amended December 28, 1989, concerning your employment
by and consulting arrangement with The Lubrizol Corporation
("Corporation") and your acceptance of that employment.  This
Amendment is being entered into in order to secure to the
Corporation the benefits of your services as an employee or
consultant during the remainder of your expected business
career.  The Corporation desires that you remain an active
employee or consultant of the Corporation until age 70,
notwithstanding that you stepped down as an officer of the
Corporation in April of 1992 because of the Corporation's
mandatory policy that senior corporate officers relinquish
their elected positions at age 65.  The Corporation recognizes
that this Agreement will require you to forego your goals of
continuing in the practice of law and of consulting in
international business development and operations subsequent to
your retirement from, and completion of any period of
consulting with, the Corporation.

        The Corporation recognizes that you are accommodating
your future career goals to its needs, and are prepared to
continue to forego certain opportunities which are very
attractive to you, both financially and professionally.  In
addition, you have further accommodated your personal desires
to the needs of the Corporation by deferring your retirement as
an employee.  Accordingly, in consideration of the premises and
the receipt of $1.00 and other valuable consideration, the
sufficiency of which is acknowledged, the Corporation is
pleased to set forth the following amended terms relating to
your continued employment by and consulting agreement with it,
by amending the Agreement as follows:

        1.    Paragraph 2(b) of the Agreement shall be amended
to read as follows:

                   (b) Notwithstanding the provisions of
              Paragraph 2(a) above, you may, by 60 days prior
              written notice to the Corporation, elect to end
              the Employment Term on or after December 31, 1992
              and commence the Consulting Period at the end of
              the Employment Term.

        2.    Paragraph 3 of the Agreement shall be amended to
read as follows:

              Your principal duties and authority during the
              Employment Term after April 27, 1992 will be to
              serve in the position of Counselor to the

              Chairman of the Corporation, as Chairman,
              Lubrizol International, Inc., and as a member of
              the management committee of the Corporation as if
              a senior corporate officer.  You will continue to
              be a corporate representative on various other
              boards of affiliates of the Corporation.  Your
              duties and responsibilities will not require you
              to relocate outside the greater Cleveland area
              without your consent, and will give appropriate
              consideration to your age, health and skills, and
              will be commensurate with your status and stature
              with the Corporation.

         3.   Paragraph 4 of the Agreement shall be amended by
adding the words "and grants of stock options" to the last
sentence thereof after the words "merit raises."

         4.   Paragraph 5(a)(i) of the Agreement shall be
amended to read as follows:

              (i) a "quarterly amount," payable on the first
              day of the Consulting Period (prorated for the
              balance of the calendar quarter) and on the first
              day of each subsequent calendar quarter in
              advance, equal to the product of 400 times the
              "hourly rate." The initial hourly rate shall be
              

   4

              one one thousand eight hundredth (1/1800th) of
              the annualized economic value to you (without
              considering the impact of federal, state or local
              income or other taxes) of the compensation and
              benefits provided to you by the Corporation for
              the calendar year in which the Employment Term
              ends, as determined in this paragraph 5(a)(i),
              but in no event less than the value of such
              compensation and benefits for the calendar year
              1992.  The initial hourly rate shall be increased
              or decreased on each January 1 commencing in the
              year after the year in which the Employment Term
              ends by the "inflation adjustment." The
              inflation adjustment shall mean an adjustment as
              of such January 1 to reflect, on a cumulative
              basis, the increase or decrease, in the Gross
              National Product Price Deflator published by the
              Bureau of Economic Analysis of the U.S.
              Department of Commerce as of the September 30
              immediately preceding each such January 1
              compared to the amount so published as of
              September 30 in the year prior to the year in
              which the Employment Term ends; provided that the
              hourly rate shall never be less than that set
              forth in the second preceding sentence.  Should

              publication of such index cease, there shall be
              substituted such alternative index as you, with
              our concurrence, determine most closely
              approximates the Gross National Product Price
              Deflator.  The determination of the economic
              value to you of your compensation and benefits
              for the calendar year in which the Employment
              Term ends shall equal the economic value of such
              compensation and benefits for the calendar year
              1992, which value has been agreed upon by the
              Corporation and you, increased on a compound
              annual basis by the percentage increase in your
              base compensation from the Corporation for each
              calendar year subsequent to 1992 to and including
              the calendar year in which the Employment Term
              ends.

         5.   Paragraph 5(b)(ii) of the Agreement shall be
amended to read as follows:

                   (ii) Notwithstanding Paragraph 5(b)(i), (A)
              you may by giving not less than 60 days prior
              written notice to the Corporation, reduce the
              number of days you will make yourself available

              for advice and counsel during the remaining
              calendar quarters of the Consulting Period to the
              equivalent of thirty-seven and one-half (37-1/2)
              eight hour days per calendar quarter, and (B) if
              in your judgment the mental or physical health of
              you or your wife necessitates the reduction
              described in this clause (B) of this sentence,
              you may by giving not less than 60 days prior
              written notice to the Corporation (which notice
              may be given in conjunction with a notice under
              clause (A) of this sentence), reduce the number
              of days you will make yourself available for
              advice and counsel during the remaining calendar
              quarters of the Consulting Period to the
              equivalent of twenty-five (25) eight hour days
              per calendar quarter.  If the Corporation
              challenges your determination of health
              necessity, the determination shall be made by a
              physician or physicians selected by you and
              acceptable to the Corporation.  Any such
              reduction or reductions shall commence with the
              calendar quarter next following the giving of
              such notice, and the quarterly amount for such
              quarter and all subsequent calendar quarters
              shall be reduced as provided in Paragraph
              5(a)(ii).

             services as a consultant, such reimbursement to

             practices.  In addition, the Corporation shall

             rent, utilities, furniture and equipment and the
             services of one employee; provided, however, that
             if you perform consulting services for any person
             or entity other than the Corporation or any of
             its affiliates, you shall prorate your expenses
             based on the number of hours you perform
             consulting services for such other person or
             entity and for the Corporation.

        7.   Paragraph 7 of the Agreement shall be amended to
