                                PROXY STATEMENT
--------------------------------------------------------------------------------

                               VOTING INFORMATION
--------------------------------------------------------------------------------

What may I vote on?

     The Board of Directors asks for your vote on one proposal:

      --      Election of nominees to serve on the Board of Directors

Who can vote?

     People who owned shares at the close of business on March 7, 2003, can vote
at the annual meeting. On March 7, 2003, there were 51,456,997 outstanding
shares of Lubrizol. Each share is entitled to one vote. This proxy statement and
the enclosed proxy card were first mailed to shareholders on or about March 19,
2003.

How do I vote?

     You can vote any one of three ways:

      --      By Telephone: Call the toll-free number (at no cost to you) on
              your proxy card to vote by telephone. Telephone voting is
              available 24 hours a day. Easy-to-follow voice prompts allow you
              to vote your shares and confirm that your vote has been properly
              recorded. Our telephone voting procedures are designed to verify
              shareholders by using the individual control numbers provided on
              the proxy cards.

              IF YOU VOTE BY TELEPHONE, YOU DO NOT NEED TO RETURN YOUR PROXY
              CARD.

      --      Over the Internet: Visit the Web site listed on your proxy card to
              vote over the Internet. Internet voting is available 24 hours a
              day. As with telephone voting, you will use the control number
              listed on your proxy card, and you will be given the opportunity
              to confirm that your vote has been properly recorded.

              IF YOU VOTE OVER THE INTERNET, YOU DO NOT NEED TO RETURN YOUR
              PROXY CARD.

      --      By Mail: Mark, sign, date and mail the enclosed proxy card to
              American Stock Transfer & Trust Company in the enclosed
              postage-paid envelope.

     If you sign and return your proxy card or use the telephone or Internet
voting procedures, but do not indicate how you wish to vote, your shares will be
voted FOR the proposal. If you indicate that you abstain, you will be counted as
present at the annual meeting for purposes of determining whether there is a
majority of outstanding shares at the meeting and you will be counted as voting
(but not for or against) that issue. Any broker nonvote also will be counted as
present at the annual meeting for purposes of determining whether there is a
majority of outstanding shares at the meeting but will not be counted as voted.

     We are not aware of any other business which will be presented at the
annual meeting. But, if there is other business that is properly presented at
the meeting, your signature on a proxy card or through the telephone or Internet
procedures gives authority to W.G. Bares, Chairman and Chief Executive Officer;
C.P. Cooley, Vice President and Chief Financial Officer; and L. M. Reynolds,
Corporate Secretary and Counsel, to vote on those matters in their best
judgment.

                                        1


Can I revoke my vote?

     You may revoke your proxy at any time before it is voted at the meeting by:

      --      notifying Lubrizol's corporate secretary in writing;

      --      voting at a later time by telephone or over the Internet;

      --      returning a later-dated proxy card; or

      --      voting in person at the annual meeting.

     Your most recent vote will be the one used as your vote.

Who tabulates the vote?

     American Stock Transfer & Trust Company serves as the independent tabulator
of votes and inspector of elections. It will report the voting results to us.
However, it will not identify to us how you voted on any issue unless:

      --      there is a contested election for the Board of Directors;

      --      it is required by law; or

      --      you request it.

Who is paying for this proxy solicitation?

     We are paying for the cost of soliciting your vote, including the cost of
mailing the proxy statement and proxy card as well as the costs of the telephone
and Internet voting procedures. We will, upon request, reimburse brokerage
houses, custodians, nominees and others for the out-of-pocket and reasonable
clerical expenses they incur in connection with this proxy solicitation.

Can I help Lubrizol save money by reducing the number of proxy materials sent to
my house?

     Yes. In accordance with the notice we sent with your December 2001
dividend, we are saving money on printing and mailing costs by sending only one
proxy statement and annual report to you and another shareholder if you have the
same last name and address (unless you have told us otherwise). If you want to
receive a separate copy of the annual report or proxy statement either now or in
the future, you can contact our transfer agent at the following address:
American Stock Transfer & Trust Company, 59 Maiden Lane, Plaza Level, New York,
NY 10038, or by telephone at 1-800-627-2303. If you currently share an address
with another Lubrizol shareholder and in the future wish to have just one proxy
statement and annual report sent to your address, please contact our transfer
agent at the address or telephone number above.

     If you hold stock through a bank, broker or other holder of record, you can
contact them about receiving single or multiple copies of the proxy statements
and annual reports.

Instead of receiving a paper copy, can I access the proxy statement and the
annual report electronically?

     The proxy statement and 2002 annual report are on our Internet site at
www.lubrizol.com/Investors/financial.htm.

     You can elect to view future proxy statements and annual reports over the
Internet instead of receiving paper copies in the mail. You can choose this
option and save us the cost of producing and mailing these documents by
following the instructions provided on your proxy card. If you chose this
option, we will furnish you with instructions next year containing the Internet
address to access our proxy statement and annual report, but you will not
receive paper copies of either document.

     If you hold stock through a bank, broker or other holder of record, check
the information provided by them for instructions on how to elect to view future
proxy statements and annual reports over the Internet. Most shareholders who
hold stock through a bank, broker or other holder of record and who elect
electronic access will receive an e-mail next year containing the Internet
address to access our proxy statement and annual report.

three-year term that will end in 2006. If any of these persons becomes
unavailable for election, your signed proxy will be voted for the election of
any person who is recommended by the Organization and Compensation Committee or
will be voted in favor of holding a vacancy to be filled by the directors. The
nominated persons who receive the greatest number of votes will be elected to
the open director positions.

                                BOARD COMMITTEES
--------------------------------------------------------------------------------

     The Board of Directors held nine meetings during 2002. The board has
several standing committees, including an Organization and Compensation
Committee and an Audit Committee.

ORGANIZATION AND COMPENSATION COMMITTEE

     The Organization and Compensation Committee held eight meetings during
2002. Its principal functions are to:

      --      Review corporate governance annually.

      --      Review and recommend candidates for election as directors.

      --      Review and recommend candidates for election as officers.

      --      Review and authorize compensation for directors and officers.

      --      Evaluate the performance of the chief executive officer.

      --      Designate employees to receive grants of stock options and other
              stock awards and determine the type and size of the awards.

      --      Determine the size of the fund pools for the profit sharing plan,
              year-end variable compensation plan and the performance pay plan.

      --      Designate employees to receive awards under the performance pay
              plan.

     This committee will consider shareholder recommendations for director
nominations. These recommendations should be submitted in writing to Lubrizol's
corporate secretary by January 1 before the annual meeting.

     The members of this committee are all of the outside directors and are
unrelated to Lubrizol. The chairman of this committee serves as the lead outside
director for purposes of chairing regularly scheduled meetings of outside
directors and for other responsibilities which the outside directors designate.
Gordon D. Harnett, chairman of this committee, currently is lead outside
director.

AUDIT COMMITTEE

     The principal functions of the Audit Committee are to:

      --      Annually appoint the independent auditors.

      --      Annually evaluate with management the performance of the
              independent auditor. The independent auditor is ultimately
              accountable to the board and the Audit Committee.

      --      Review with the independent and internal auditors the planned
              scope and results of audits.

      --      Hold conferences and reviews with the auditors as desired by the
              committee or the auditors.

      --      Review matters that affect financial statements and the results of
              the independent auditor's reviews, annual audit and report.

      --      Review the adequacy and effectiveness of the internal audit
              function.

      --      Oversee Lubrizol's internal control structure.

      --      Provide oversight of the activities of the chief ethics officer
              and review procedures for monitoring compliance with Lubrizol's
              Policy on Ethical and Legal Conduct.

                                        7


      --      Report to the board the results of these reviews and conferences
              and submit to the board any recommendations of the committee.

     The Board of Directors has adopted a written charter for this committee. In
performing its functions, the Audit Committee acts in an oversight capacity for
Lubrizol's management processes and systems, internal control structure,
financial reporting and risk management. It is not responsible for preparing or
assuring the accuracy of Lubrizol's financial statements or filings, or
conducting audits of the financial statements.

     The members of the Audit Committee are David H. Hoag (Chairman), Victoria
F. Haynes, William P. Madar, Ronald A. Mitsch and Daniel E. Somers. The board
has determined that each of the members is independent under the rules of the
New York Stock Exchange.

AUDIT COMMITTEE REPORT

     The Audit Committee reviews Lubrizol's financial reporting process on
behalf of the Board of Directors. The committee held four meetings during 2002.
During these meetings, the committee reviewed and discussed the audited
financial statements for 2002 separately with management and Lubrizol's
independent auditors, Deloitte & Touche LLP. The discussions with Deloitte &
Touche included matters required to be discussed by the Statement on Auditing
Standards No. 61. In addition, the committee received from Deloitte & Touche
written independence disclosures and the letter required by Independence
Standards Board Standard No. 1 and discussed with Deloitte & Touche its
independence. Based on the review of the audited financial statements and the
discussions described above, the committee recommended to the Board of Directors
that the audited financial statements be included in Lubrizol's Annual Report on
Form 10-K for the year ended December 31, 2002, for filing with the Securities
and Exchange Commission.

                             DIRECTOR COMPENSATION
--------------------------------------------------------------------------------

     Directors who are not Lubrizol employees receive a yearly cash retainer fee
of $16,000, plus $1,000 for each board meeting they attend and $1,000 for each
committee meeting they attend. If a committee meeting is held on a different day
from a board meeting, they receive $1,200 for the committee meeting.

     Directors who are not Lubrizol employees may participate in a deferred
compensation plan for directors. Under this plan, directors may defer all or any
portion of their yearly fee and meeting attendance fees and have these amounts
credited to various cash investment accounts and/or a share unit account. The
investment returns of the cash investment accounts equal the performance of the
investment portfolios designated by the Organization and Compensation Committee.
The number of share units credited to the share unit account is based on the
price of Lubrizol shares on the day the share units are credited to the account
and includes additional share units credited for quarterly dividends paid on
Lubrizol shares. When a person is no longer a director, cash is distributed from
the person's cash account and Lubrizol shares are issued equal to the number of
share units in the person's share unit account.

     On the date of each annual meeting, each director who is not a Lubrizol
employee automatically receives an option to purchase 2,500 Lubrizol shares
under the 1991 Stock Incentive Plan.

     Directors who are not Lubrizol employees also participate in a deferred
stock compensation plan. Under this plan, each nonemployee director receives 500
share units on each October 1 and is credited with additional share units for
quarterly dividends paid on Lubrizol shares. When a person is no longer a
director, Lubrizol shares are issued equal to the number of share units in the
person's account.

     The Lubrizol Corporation Board of Directors Guidelines are attached as
Appendix A to this proxy statement.

STOCK INCENTIVE PLANS

     Our 1991 Stock Incentive Plan allows grants of incentive and nonstatutory
stock options, as well as stock appreciation rights and restricted and
nonrestricted stock awards. Any of our employees and our subsidiaries' employees
may be selected to participate in the plan. The plan is administered by the
Organization and Compensation Committee, which selects participants and
determines the type and amount of awards granted. The plan will expire on May 1,
2012.

     The number of shares available under the plan during a calendar year is 1%
of the outstanding shares on January 1 of that year, plus any unused shares from
previous years. The option price for stock options is not less than the average
of the high and the low market prices of shares on the

                                        12


grant date. The term of each option is fixed by the committee. Participants can
exercise their options 50% after one year, 75% after two years and 100% after
three years. All outstanding options become fully exercisable upon a change of
control.

     Under this plan, any person who pays the option price of options granted
prior to March 27, 2000, under the plan with shares already owned will
automatically receive a new option grant for the number of shares used to pay
the option price. These option grants are called reload options. For options
granted on or after March 27, 2000, the committee in its discretion may grant a
reload option for the number of shares used to pay the option price. Persons may
not transfer shares acquired from the exercise of a reload option while still an
employee or director unless they have met any applicable share ownership
guidelines. We eliminated reloads for new options granted on or November 11,
2002.

     We also have options outstanding under our 1985 Employee Stock Option Plan.
The only options granted under this plan are reload options to employees who pay
the option price of options granted under this plan with shares they already
own. In these cases, the committee in its discretion may grant a reload option
under this plan for the number of shares used to pay the option price.

     The following tables show option transactions for the named executive
officers during 2002. No stock appreciation rights were granted, exercised or
outstanding in 2002.

(1) This column shows the average of the high and low sales prices as reported
    on the New York Stock Exchange on the grant date.

(2) The assumed rates of appreciation shown are established by the Securities
    and Exchange Commission and are not meant to represent either past or future
    appreciation rates for Lubrizol shares. If the assumed annual appreciation
    rates were applied to the fair market value of Lubrizol shares at December
    31, 2002 ($30.46 per share), then at the end of a 10-year option term, the
    per share market price of the shares would be $30.46 at a 0% appreciation
    rate, $49.62 at a 5% appreciation rate and $79.01 at a 10% appreciation
    rate.

(3) The amount shown reflects a reload option granted in an amount equal to the
    number of common shares used in the payment of the exercise price of another
    option.

(4) Expiration dates range from April 27, 2002, through June 24, 2012.

(1) Dollar-based target awards are determined by the Organization and
    Compensation Committee in the December prior to the three-year performance
    period. A portion of the award is converted into a number of shares based on
    the price of Lubrizol stock on the date of the award. There are no voting or
    dividend rights associated with the shares until the end of the performance
    period and payouts, if any, are made. Target awards correspond to a
    pre-determined three-year earnings per share growth rate target. The
    three-year earnings per share growth rate must reach a minimum
    pre-determined threshold before any payout would be made. The maximum payout
    corresponds to a three-year earnings per share growth rate that is more than
    twice the target growth rate.

(2) The performance period runs from 2003 through 2005. Payouts, if any, will be
    made in 2006.

              compensation policies, including comparisons to the policies and
              practices of other companies;

      --      Relevant trends in executive compensation practices;

      --      Lubrizol's financial performance;

      --      Lubrizol's business performance;

              according to Lubrizol's performance and according to individual
              contribution, including the individual's commitment to Lubrizol.

Cash Compensation of Employees Generally

     The cash compensation of most employees, including the executive officers
named in the compensation table in this proxy statement, consists of (1) base
salary, (2) quarterly pay and (3) variable pay.

     Quarterly pay is a fixed percentage of base salary determined by an
employee's length of service. Employee base salary plus quarterly pay is
designed to be within the mid-level range of salaries for persons having similar
jobs in the chemical and related industries.

     Variable pay authorized by the committee for employees, other than
executive officers and other key employees, is paid in the first quarter and is
based upon a percentage of the previous year's net income. Variable pay is
allocated to employees based on a uniform percentage of each employee's base
salary.

Cash Compensation of Executive Officers

     The base salary and quarterly pay practices for employees also apply to
executive officers.

     For executive officers, eight separate surveys selected by the committee's
compensation consultant are used to determine base salary plus quarterly pay.
These surveys include more companies than the published industry
line-of-business indices used to compare total shareholder return on page 18 of
this proxy statement; however, 10 peer chemical companies are included in both
the salary surveys and the published industry indices. In addition, for the five
highest paid executives, total compensation levels and practices are analyzed
using compensation data published in each peer organization's proxy statement.
This analysis considers fixed salary, annual incentive, total cash compensation,
long-term incentives and total compensation.

     The committee also reviews Lubrizol's three-year performance compared to a
peer group of 17 companies by analyzing total shareholder return, economic value
added, return on equity, return on assets and growth in earnings per share. This
analysis helps ensure that total executive pay is in alignment with Lubrizol's
performance relative to its peer group.

     The committee administers the executive compensation policy with the
objective of keeping executive compensation comparable with other companies in
the chemical and related industries.

                                        15


The average executive base salary plus quarterly pay in 2002 was slightly below
the mid-level range when compared to fixed compensation paid by companies in the
surveys.

     Executive officers and other key employees can receive variable cash
compensation under a performance pay plan. The committee determines a percentage
of annual net income to establish the amount available under this plan. For
2002, this percentage was based on objective financial measures and objective
and subjective performance measures for initiatives relating to our strategies
for (1) running the business and (2) changing the business. The objective
financial measures include earnings per share, contribution income from the
fluid technologies for industry, paints, coatings and inks, process chemicals,
defoamers and metalworking businesses, and emulsified products sales.

     Sixty-six percent of the weighting for all the performance measures is
based upon financial measures with the largest portion weighted to earnings per
share. The payout under the performance pay plan will vary based upon goal
accomplishment. Even if other goals are reached, earnings per share must reach a
minimum predetermined threshold before the plan will make payments.

     The committee has the discretion to adjust the amount available under the
performance pay plan and to determine individual payouts under the performance
pay plan based upon an executive's level of responsibility, recommendations by
executive management and a subjective judgment by the committee of the
executive's contribution to Lubrizol's financial and business performance.

Stock Compensation for Executive Officers

     Lubrizol uses stock options and performance share stock awards as forms of
long-term incentive compensation for executive officers and other key employees.

     Stock Options

     The committee determines the number of stock options granted to an
executive based on the individual's level of responsibility and performance,
recommendations by executive management and a subjective judgment by the
committee of the executive's contribution to financial and business performance.
The committee does not take into consideration existing awards held by the
executive when making new grants. For 2002, the committee set the total number
of stock options for annual grants to the five highest-paid executive officers
at the mid-level range of long-term incentive awards within the peer chemical
companies. For the other executive officers, the comparison was with general
industrial companies.

     Performance Share Stock Awards

     The committee granted performance share stock awards to executive officers
in 1997. Newly elected executive officers receive proportional performance share
stock awards at the time of hire or promotion. When the performance share stock
awards vest, Lubrizol will issue shares equal to the number of performance share
stock awards granted. These performance share stock awards will vest if the
closing market price of Lubrizol shares reaches $45 for ten consecutive trading
days. Otherwise, these awards will vest on March 24, 2003. No performance shares
vested in 2002.

Deductibility of Executive Compensation

     Section 162(m) of the Internal Revenue Code of 1986 limits the
deductibility of compensation paid to specified executive officers of public
companies. All compensation paid for 2002 to Lubrizol executive officers,
including the compensation element of shares received under Lubrizol's stock
option plans, qualified for deduction.

Compensation of the Chief Executive Officer

     The committee's intent is to set Mr. Bares' base salary plus quarterly pay
within a range that is competitive with the fixed salaries of chief executive
officers in the chemical and related industries.

                                        16


The committee increased Mr. Bares' base salary by 5% effective August 2002, 18
months after the previous increase. Mr. Bares' base salary and quarterly pay is
almost equal to the mid-level range of comparable salaries.

     Mr. Bares received 52% of his total cash compensation for 2002 from the
performance pay plan. For 2002, earnings per share exceeded the 2002 minimum
threshold.

     In setting Mr. Bares' total compensation, the committee considers various
other aspects of corporate performance including market position, productivity,
product leadership, personnel development, employee attitudes, public
responsibility, quality practices and the balancing of short-term and long-term
goals. For 2002, Mr. Bares' total compensation was at the mid-level range of
comparable total compensation of chief executive officers of peer chemical
companies.

     In determining the number of stock options granted to Mr. Bares in 2002,
the committee considered the factors described immediately above, as well as his
position within Lubrizol and stock option grant comparisons with peer chemical
companies.

     Lubrizol's share ownership guidelines require Mr. Bares to hold shares
valued at four times his annual fixed pay. At year end, he owned over five times
his annual fixed pay in shares.

  2003 Compensation Practice Changes

     During 2002, the committee met extensively to consider and adopt changes to
the compensation practices for key executive officers and the chief executive
officer. The changes are meant to more closely align their compensation with
Lubrizol's performance and shareholder interest. These changes are effective
beginning with 2003. No new stock options or performance shares will be granted
to certain key executive officers in 2003. Instead a long-term performance
incentive program will provide a target payout of cash and shares in 2006 if a
three-year earnings per share growth target is met. The three-year earnings per
share growth target was set by the committee prior to the beginning of 2003. The
payout percentage will vary up or down based upon the actual three-year earnings
per share growth. The three-year earnings per share growth must reach a minimum
threshold of the pre-determined target or no long-term incentive benefits will
be paid.

PERFORMANCE COMPARISONS

     The following chart compares our combined total shareholder returns for the
five years ended December 31, 2002, to the combined total shareholder returns of
(a) the Standard & Poor's Industrial Index, (b) the Dow Jones Chemical Index and
(c) the Standard & Poor's Specialty Chemical Index.

     We believe we have a peer group relationship with companies in these last
two indices. However, no single peer index or peer company is totally comparable
to our business. The peer company indices used include companies which supply
specialty chemicals to a wide variety of markets. Some of our direct competitors
are chemical divisions that represent small portions of large oil companies.
These chemical divisions are not included in the peer comparison because
information is not available to us which shows those divisions separately from
the parent company.

     The chart assumes the investment of $100 on December 31, 1997, and the
immediate investment of all dividends.

                  EMPLOYEE AND EXECUTIVE OFFICER BENEFIT PLANS
--------------------------------------------------------------------------------

     In addition to the stock option and variable compensation plans described
in this proxy statement and the group health, life and disability insurance
plans available to all employees, we also have the following plans for employees
and executive officers.

PENSION PLANS

     We have a qualified pension plan for all employees. We also have a basic
supplemental defined benefit plan which provides highly paid employees with the
portion of their retirement benefits not payable from the pension plan because
of tax law limitations. In addition, we have a special officers'

                                        18


supplemental defined benefit plan which covered two officers as of December 31,
2002, and is described in the paragraph below the pension table.

     Benefits under the pension plan and the related basic supplemental plan are
based on a final average pay formula or a career average pay formula, whichever
produces the higher benefit to the employee. The table below uses the final
average pay formula because it produces the higher benefit at the pay levels
shown.

     Final average pay is an average of an employee's highest five consecutive
years out of the last ten years of pay. Pay for the plans consists of base
salary (unreduced for elective before-tax savings contributions and before-tax
cafeteria plan contributions), quarterly pay, overtime pay, shift premium
differentials, vacation and holiday pay, paid variable compensation, long-term
disability benefits and (for purposes of the basic and special supplemental
plans) cash compensation deferrals. Pay used to determine benefits for each of
the named executive officers is equal to the amounts shown in the salary and
bonus columns for them in the summary compensation table in this proxy
statement.

     Benefits are based on a 10-year certain and life annuity. Employees hired
before February 1, 1984, may elect a lump sum option. Other payment options
available to all employees are a joint and 100% or 50% survivor annuity.

     The final average pay formula limits years of service to 30. The estimated
credited years of service for each of the named executive officers (after this
30-year service limitation) is as follows: Mr. Bares, 30 years; Mr. Kirk, 30
years; Dr. Hill, 20 years; Mr. Cooley, 5 years; and Mr. Bogus, 3 years.

     The following table shows the estimated annual retirement benefits payable
at age 65 under the pension plan and the basic supplemental defined benefit plan
in the final average pay and years of service categories shown. The benefits are
shown as a 10-year certain and life annuity.

$  200,000 ................   27,140      40,710      54,280      67,850      81,420      81,420

 1,000,000 ................  143,140     214,710     286,280     357,850     429,420     429,420
 1,200,000 ................  172,140     258,210     344,280     430,350     516,420     516,420
 1,400,000 ................  201,140     301,710     402,280     502,850     603,420     603,420
 1,600,000 ................  230,140     345,210     460,280     575,350     690,420     690,420


     As of December 31, 2002, Mr. Bares and Dr. Hill were participants in the
special officers' supplemental defined benefit plan. Benefits under this plan
are based on an average of the highest three consecutive years of pay during the
last ten years. The plan limits years of service to 30 and computes benefits on
the basis of a 10-year certain and life annuity. Benefits are reduced for Social
Security and payments made under other Lubrizol benefit plans. After making all
the deductions required under the plan, the estimated additional annual benefit
payable under this plan at age 65 (assuming current final average pay) to Mr.
Bares is $2.5 million and to Dr. Hill is $239,000.

PROFIT SHARING AND SAVINGS PLAN

     We have a qualified profit sharing and savings plan for all employees. Each
year, the Board of Directors determines the portion of Lubrizol profits that
will be contributed to the plan. Profit sharing contributions are allocated to
employees' accounts based on their pay.

                                        19


     In addition, employees may contribute up to 18% (16% for highly compensated
employees) of base pay to the plan as a before-tax contribution. Lubrizol
matches 50% of the employee's before-tax contributions up to 4% of the
employee's base pay. Employees also may make after-tax contributions subject to
an overall limit of 18% (16% for highly compensated employees) of base pay for
their total before-tax and after-tax contributions.

     Employees may direct the investment of their contributions and the company
match among a Lubrizol share fund and ten other funds with a range of investment
characteristics.

     Employees vest in profit sharing and matching contributions at a rate of
20% per year of service. The plan allows distribution of an employee's vested
account balance after retirement, death or other termination of employment.

DEFERRED COMPENSATION PLANS

     We have a deferred compensation plan for executive officers. Under this
plan, executive officers may defer all or any portion of their total annual pay
and have these amounts credited to various cash investment accounts and/or a
share unit account. The investment returns of the cash investment accounts equal
the performance of the investment portfolios designated by the Organization and
Compensation Committee. The number of share units credited to the share unit
account is based on the price of Lubrizol shares on the day the share units are
credited to the account and includes additional share units credited for
quarterly dividends paid on Lubrizol shares. At the end of the deferral period,
the deferrals and earnings are distributed to the participant. Cash is
distributed from the cash account and Lubrizol shares are issued equal to the
number of share units in the participant's share unit account.

     In addition, we have another deferred compensation plan for some executive
officers. Under this plan, participants may defer any amount of their variable
pay under the performance pay plan. Deferred amounts are converted into share
units based on the current market price of Lubrizol's shares, which are then
multiplied by 1.25. Additional share units are credited for quarterly dividends
paid on Lubrizol shares. At the end of the deferral period, which is at least
three years, Lubrizol shares are issued equal to the number of share units in
the participant's account.

SUPPLEMENTAL RETIREMENT PLAN

     We have a supplemental retirement plan for Donald W. Bogus under which 500
share units are credited to an account on each April 1 until his retirement from
Lubrizol. The account is also credited with additional share units for quarterly
dividends paid on Lubrizol shares. Upon his retirement, he may elect to receive
the balance of his account in cash or common shares.

EXECUTIVE DEATH BENEFIT PROGRAM

     The Organization and Compensation Committee selects executive officers to
participate in an executive death benefit program. This program provides a
benefit to the executive officer's designated beneficiary following the
executive officer's death. The death benefit is 250% of the participant's base
salary plus quarterly pay for a designated year, reducing to 150% at age 70 and
100% at age 75.

EXECUTIVE AGREEMENTS

     We have employment termination agreements with senior executives, including
Messrs. Bares, Hill, Cooley, Kirk and Bogus. Each termination agreement provides
that, in the event of a change in control of Lubrizol, the executive will be
employed by Lubrizol for up to three years at responsibility, salary and benefit
levels equal to those immediately preceding the change in control. If the
executive's employment is terminated during those three years for reasons other
than death,

                                        20


permanent disability, reaching age 65 or for cause, or if the executive
terminates employment in specified circumstances, the benefits provided to the
executive are:

     (1)  a lump sum payment equal to three times the salary and other forms of
          cash compensation in effect at the time of termination, and

     (2)  continued employee benefit coverage for the remainder of the three
          years.

     The termination agreements also provide that the executive will receive an
amount which will cover any excise taxes that apply.

     Each executive has agreed, if the executive accepts any benefits under the
termination agreement, not to compete with Lubrizol for one year after
termination of employment after a change in control.

     Assuming a change in control were to occur and all of the executive
officers who have termination agreements were terminated as of January 1, 2003,
the estimated amount of payments which we would have to make under the
termination agreements (including amounts to cover excise taxes) is $30 million.

EMPLOYEE SEVERANCE COMPENSATION PLAN

     We also have a severance compensation plan that provides for a severance
payment to employees if, within 15 months after a change in control of Lubrizol,
their employment is terminated for any reason other than death, permanent
disability, voluntary retirement or for cause. Executives who receive payments
under the executive termination agreements described above will not receive
severance payments under the severance compensation plan.

     For an employee with five or more years of service with Lubrizol, the
benefit under the severance compensation plan is a lump sum payment equal to the
total cash compensation received by the employee in the preceding 12-month
period. Employees with less than five years but more than six months of service
would receive a lesser amount proportionate to their length of service.

                       SECTION 16(a) BENEFICIAL OWNERSHIP
                              REPORTING COMPLIANCE
--------------------------------------------------------------------------------

     Section 16(a) of the Securities Exchange Act of 1934 requires our officers
and directors, and some persons who own more than 10% of our shares, to file
reports of share ownership and change in ownership with the Securities and
Exchange Commission, with a copy to us. We are not aware of any shareholder who
owns more than 10% of our shares and is required to file these reports.

     Based solely on a review of the copies of the forms furnished to us during
or for 2002 and written statements from officers and directors, we believe that
all officers and directors filed on time all reports required during 2002 and
any prior year.

--------------------------------------------------------------------------------

                            APPOINTMENT OF AUDITORS
--------------------------------------------------------------------------------

     The Audit Committee appointed Deloitte & Touche LLP, independent auditors,
to audit the financial statements of Lubrizol for the year 2003.

     During 2002, Lubrizol engaged Deloitte & Touche to render a variety of
services, including the audit of Lubrizol's financial statements. A Deloitte &
Touche representative will attend the annual meeting, will have the opportunity
to make a statement and will be available to answer questions.

                                        21


AUDIT FEES

     The total fees billed or expected to be billed by Deloitte & Touche LLP for
the audit of Lubrizol's financial statements for the year ended December 31,
2002 and for the reviews of the quarterly financial statements included in
Lubrizol's Forms 10-Q for 2002 is $1,065,015.

FINANCIAL INFORMATION SYSTEMS DESIGN AND IMPLEMENTATION FEES

     Deloitte & Touche LLP did not render financial information systems design
and implementation services during 2002.

ALL OTHER FEES

     The total fees billed for services rendered by Deloitte & Touche LLP to
Lubrizol during 2002, other than audit fees, was $733,363, including audit
related services of $334,970, tax services of $372,391 and other non-audit
services of $26,002. Audit related services include due diligence procedures
associated with mergers and acquisitions, employee benefit plan audits and other
attest services related to affiliated companies. After separate discussions with
Deloitte & Touche and management, the Audit Committee has considered whether the
provision of these other services is compatible with maintaining Deloitte &
Touche's independence.
--------------------------------------------------------------------------------

               SHAREHOLDER PROPOSALS FOR THE 2004 ANNUAL MEETING
--------------------------------------------------------------------------------

     Any shareholder who wants to present a proposal at the 2004 Annual Meeting
of Shareholders and have it included in our proxy materials must send us the
proposal no later than November 19, 2003. Shareholder proposals submitted after
that date but on or before February 27, 2004, may be presented at the annual
meeting but will not be included in the proxy materials. If a shareholder
proposal is received after February 27, 2004, the persons named on the proxy
card may vote in their discretion regarding the proposal all of the shares for
which we have received proxies for the annual meeting.

                            THE LUBRIZOL CORPORATION

                    BOARD OF DIRECTORS GOVERNANCE GUIDELINES

1. COMPOSITION

     The Regulations provide that the Board will have nine to thirteen Directors
with both the shareholders and the Board having the authority to set the number
within that range. The optimum size of the Board should be ten to twelve
members, including one inside Director. The Chief Executive Officer will
normally be the Chairman of the Board.

     Board members should be recruited from the broadest geographic region
possible within the U.S. The Board should also seek candidates having broad
international experience. Approximately half of the outside Directors should be
out-of-town members.

     The Board should represent a broad spectrum of individuals with experience
who are able to contribute to the success of the Corporation. Assessment of new
members should include the issues of independence, diversity, age and skills
necessary to the needs of the Board at the time.

2. MEETINGS

     The Board holds an organizational meeting to elect officers after each
Annual Meeting of Shareholders at which Directors are elected. The Annual
Meeting and the organizational meeting of the Board are held on the fourth
Monday of April. The Board establishes other regular meetings at such times and
places as it decides. Board meetings are usually held monthly with the exception
of January, May, August and October. Dates are determined in advance and are
usually the fourth Monday of the month. A majority of Directors then in office
constitutes a quorum for Board meetings.

     Meeting days normally begin at 7:30 AM and conclude at 4:00 PM.

     On a timely basis before each meeting, management will provide an agenda
for the meeting, minutes from the last meeting and background information for
important subjects to be presented at the meeting.

     Proposed significant transactions normally should be on the agenda for at
least two consecutive meetings.

     The corporation's strategic plan should be reviewed at one meeting each
year.

     Periodically, the Board should hold meetings at other locations of the
Corporation.

3. ATTENDANCE

     The expectation for attendance at meetings is 100 percent, except for
occasional illness or unavoidable conflicts. If a Director determines that it is
not possible to attend a meeting, the Director is expected to notify the
Chairman of the Board or the Secretary of the Corporation promptly to assist in
assuring a quorum for the meeting. If a Director physically cannot attend a
Board meeting but is otherwise able to participate, it may be possible for the
Director to attend by telephone if advance arrangements are made.

4. COMMITTEES

     The Board may elect an Executive Committee and/or other Board committees
each consisting of not less than three Directors. Directors are expected to
serve on one or more committees.

                                       A-1


     Committee appointments, other than for the Organization and Compensation
Committee, will be rotated as determined by the respective Committee chairman
and the Chairman of the Board.

     The Chairman of the Board will nominate each Committee chairman, but no
Committee chairman may serve as such for more than four years.

     Currently, the Board has established four standing committees: Executive
Committee, Organization and Compensation Committee, Audit Committee and
Retirement and Savings Plans Investment Committee. The Board will review and
approve the charters of the committees at the organization meeting of the Board
of Directors after the Annual Shareholders Meeting.

5. RETIREMENT

     A Director will retire no later than the date of the Annual Meeting next
following the date on which such Director attains the age of 69.

6. CHANGE IN STATUS

     A person whose primary job responsibilities change from those he/she held
when elected to the Board will volunteer to resign from the Board. It is the
responsibility of the Organization and Compensation Committee to either accept
the resignation or ask the Director to remain on the Board.

7. FORMER CHIEF EXECUTIVE OFFICER'S BOARD MEMBERSHIP

     A former Chief Executive Officer, upon retirement from the Corporation,
will resign from the Board following a short period of time to allow for a
smooth transition to the new Chief Executive Officer.

     A former Chief Executive Officer serving on the Board during this short
transition will be considered an inside Director for purposes of corporate
governance.

8. MEMBERSHIP ON OTHER BOARDS

     Each Director has the responsibility to notify the Chief Executive Officer
and Chairman of the Board prior to accepting invitations to join other Boards of
Directors. This guideline is established to avoid potential conflicts of
interest or the appearance of conflicts of interest. Appropriate legal judgment
will be obtained as necessary.

9. LEAD OUTSIDE DIRECTOR

     The Chairman of the Organization and Compensation Committee will serve in
the capacity of lead outside Director for the purpose of chairing meetings of
outside Directors, which shall be held periodically.

10. EXECUTIVE SESSIONS OF OUTSIDE DIRECTORS

     The outside Directors of the Board will meet in Executive Session of the
Organization and Compensation Committee as required, but at least three times a
year.

11. ASSESSING BOARD PERFORMANCE

     The Organization and Compensation Committee shall conduct a periodic
assessment of the Board's performance and processes.

     This assessment should be of the Board's contribution as a whole and
specifically review areas in which the Board and/or the management believes
improvements can be made to increase the effectiveness of the Board.

                                       A-2


12. EVALUATION OF THE CHIEF EXECUTIVE OFFICER

     The Organization and Compensation Committee will conduct an annual formal
evaluation of the Chief Executive Officer and communicate it to the Chief
Executive Officer by the Chairman of the Organization and Compensation Committee
and another member of the Chairman's choosing.

     The evaluation will consider aspects of corporate performance, such as
profitability, market position, productivity, product leadership, personnel
development, employee attitudes, public responsibility, quality practices and
the balancing of short-term and long-term goals. The evaluation will reflect a
combination of objective and subjective judgment with an emphasis on the impact
on the Corporation's sustainability and competitiveness within its industry. As
part of the evaluation, the Chief Executive will prepare a self-evaluation in
accordance with the Corporation's performance planning and development process.

     The evaluation will be used by the Organization and Compensation Committee
in the course of its deliberations when considering the compensation of the
Chief Executive Officer.

13. SUCCESSION PLANNING/MANAGEMENT DEVELOPMENT

     The Chief Executive Officer will submit an annual report to the
Organization and Compensation Committee on succession planning and the
Corporation's program for management development. The Chief Executive Officer's
recommendation as to his/her successor should he/she be unexpectedly unavailable
to serve will be communicated to the Organization and Compensation Committee on
a continuing basis.

14. BOARD ACCESS TO SENIOR MANAGEMENT

     Board members have complete access to Lubrizol's management. Each Board
member has the responsibility to inform the Chief Executive Officer and Chairman
of the nature of any communication with management and to provide copies of any
written communication to the Chief Executive Officer and Chairman. The Board
encourages management to bring managers into Board meetings who can provide
additional insight into the items being discussed and/or who represent future
potential that the management believes should be given exposure to the Board.

15. REVIEW OF SHAREHOLDER PROTECTION PROVISIONS

     All shareholder protection provisions will be reviewed at least biannually.

16. RELATIONSHIP WITH SHAREHOLDERS AND INVESTORS

     Management has the authority and responsibility to speak for Lubrizol on
behalf of the Corporation and the Board of Directors. Management will provide
periodic reports to the Board regarding shareholder communications.

17. DIRECTOR COMPENSATION

     The Chief Executive Officer will report annually to the Board of Directors
on the status of Lubrizol Board compensation in relation to other comparable
U.S. manufacturing companies. The Board is authorized to set a reasonable
compensation for Directors. Any Director who is a full-time employee of the
Corporation receives no separate compensation as a Director.

18. STOCK OWNERSHIP

     Directors are encouraged to own shares of the Corporation's stock and to
increase their ownership of those shares over time. It is expected that each
Director, upon taking office, will own a minimum of 100 shares. The Board
believes that the stock compensation and stock option plans for Directors are
appropriate methods to allow Directors to increase their holdings significantly
over time.

                                       A-3
