                                     PART I
                                     ------

ITEM 1.  BUSINESS

                  The Lubrizol Corporation was organized under the laws of Ohio
in 1928. The company began business as a compounder of special-purpose
lubricants, and in the early 1930's was among the first to commence research in
the field of lubricant additives. Today, the company is a global fluid
technology company concentrating on high-performance chemicals, systems and
services for industry and transportation. The company develops, produces and
sells specialty additive packages and related equipment used in transportation
and industrial finished lubricants. The company's products are created through
the application of advanced chemical and mechanical technologies to enhance the
performance, quality and value and reduce the environmental impact of the
customer products in which they are used. The company groups its product lines
into two operating segments: chemicals for transportation and chemicals for
industry.

                  PRINCIPAL PRODUCTS. Chemicals for transportation is comprised
of additives for lubricating engine oils, such as those used in gasoline,
diesel, marine and stationary gas engines and additive components; additives for
driveline oils, such as automatic transmission fluids, gear oils and tractor
lubricants; and additives for fuel products and refinery and oil field
chemicals. In addition, the company sells additive components and viscosity
improvers within its lubricant and fuel additives product lines. Chemicals for
industry includes industrial additives, such as additives for hydraulic fluids,
metalworking fluids and compressor lubricants; performance chemicals, such as
additives for coatings and inks and process chemicals; and performance systems,
comprised principally of fluid metering devices and particulate emission trap
devices.

                  Revenues within the chemicals for transportation segment
comprised 82%, 83% and 84% of consolidated revenues in 2000, 1999 and 1998,
respectively. Additives for lubricating engine oils comprised 53%, 53% and 52%
of consolidated revenues in 2000, 1999 and 1998, respectively. Additives for
driveline oils comprised 23%, 23% and 24% of consolidated revenues for these
same respective periods. Further financial information for the company's
operating segments is contained in Note 12 to the Financial Statements, which is
included in the company's 2000 Annual Report to its shareholders and is
incorporated herein by reference.

                  Additives improve the lubricants and fuels used in cars,
trucks, buses, off-highway equipment, marine engines and industrial
applications. In lubricants, additives enable oil to withstand a broader range
of temperatures, limit the buildup of sludge and varnish deposits, reduce wear,
inhibit the formation of foam, rust and corrosion, and retard oxidation. In
fuels, additives help maintain efficient operation of the fuel delivery system,
help control deposits and corrosion, improve combustion and assist in preventing
decomposition during storage.

                  Due to the variety of oil properties and applications, a
number of different chemicals are used to formulate the company's products. Each
additive combination is designed to fit the characteristics of the customer's
base oil and the level of performance specified. Engine oils for passenger cars
contain a combination of chemical additives which usually includes one or more
detergents, dispersants, oxidation inhibitors and wear inhibitors, pour point
depressants and viscosity improvers. Other chemical combinations are used in
specialty additive systems for heavy duty engine oils used by trucks and
off-highway equipment and in formulations for gear oils, automatic transmission
fluids, industrial oils, metalworking fluids, and gasoline, diesel and residual
fuels.

             The company's performance systems products principally involve
products used in emission controls, such as catalyst, exhaust and filter systems
and precision metering devices used in blending and additive injection
operations.

                  COMPETITION. The company's chemicals for transportation
segment and chemicals for industry segment are highly competitive in terms of
price, technology development, product performance and customer service. The
company's principal competitors within its chemicals for transportation segment,
both in the United States and overseas, are Infineum, a joint venture involving
two major petroleum companies (Shell Oil Company and Exxon Mobil Corporation);
Chevron Oronite Company, a subsidiary of Chevron Corporation, a major petroleum
company; and one chemical company (Ethyl Corporation). The petroleum companies
either directly or indirectly produce lubricant and fuel additives for their own
use and also sell additives to others. These petroleum companies are also
customers of the company and may also sell base oil to the company. The company
believes, based on volume sold, that it is the largest supplier to the petroleum
industry of performance additive packages for lubricants.

                  CUSTOMERS. In the United States, the company markets its
chemicals for transportation and chemicals for industry products through its own
sales organization. The company's additive customers consist primarily of oil
refiners and independent oil blenders and are located in more than 100
countries. In 2000, approximately 43% of the company's consolidated sales were
made to customers in North America, 30% to customers in Europe and the Middle
East and 27% to customers in Asia-Pacific and Latin America. The company's ten
largest customers, most of which are international oil companies and a number of
which are groups of affiliated entities, accounted for approximately 48% of
consolidated sales in 2000. The loss of one or more of these customers could
have a material adverse effect on the company's business. Exxon Mobil
Corporation, together with its affiliates, has been the company's largest
customer within its chemicals for transportation segment during the past two
years, comprising 11% of consolidated sales in 2000 and 12% in 1999. Mobil
Corporation and Exxon Corporation completed a merger during the latter part of
1999, and the 1999 percentage includes sales to Mobil, Exxon and their
affiliates prior to the merger as well as sales to the combined entity, Exxon
Mobil Corporation, following the consummation of the merger. Sales to Mobil
Corporation comprised 9% of consolidated sales in 1998. The company's chemicals
for industry segment is not materially dependent on a single customer or on a
few customers.

                  RAW MATERIALS. The company utilizes a broad variety of
chemical raw materials in the manufacture of its additives and uses oil in
processing and blending additives. These materials are obtainable from several
sources, and for the most part are derived from petroleum. Political and
economic conditions in the Middle East have, in the past, caused and may
continue to cause the cost of raw materials to fluctuate significantly; however,
the availability of raw materials to the company has not been significantly
affected when these conditions occurred. The company expects raw materials to be
available in adequate quantities during 2001.

                  RESEARCH, TESTING AND DEVELOPMENT. The company has
historically emphasized research and has developed a large percentage of the
additives it manufactures and sells. Technological developments in the design of
engines and other automotive equipment, combined with rising demands for
environmental protection and fuel economy, require increasingly sophisticated
chemical additives to meet industry performance standards. The frequency of
changes in industry performance affects the company's technical spending
patterns.

                  Consolidated research and development expenditures were $86.4
million in 2000 and $78.3 million in 1999 and 1998. These amounts were
equivalent to 4.9%, 4.4% and 4.7% of the respective revenues for such years.
These amounts include expenditures for the performance evaluation of additive
developments in engines and other types of mechanical equipment as well as
expenditures for the development of specialty chemicals for industrial
applications. In addition, $64.4 million, $67.7 million and $72.7 million was
spent in 2000, 1999 and 1998, respectively, for technical service (testing)
activities, principally for evaluation in mechanical equipment of specific
lubricant formulations designed for the needs of petroleum industry customers
throughout the world.

                  Research, testing and development expenditures by operating
segment were as follows (in thousands of dollars):

                  The company has two research facilities at Wickliffe, Ohio,
one of which is principally for lubricant additive research and the other for
research in the field of other specialty chemicals. The company also maintains a
mechanical testing laboratory at Wickliffe, equipped with a variety of gasoline
and diesel engines and other mechanical equipment to evaluate the performance of
additives for lubricants and fuels. The company has similar mechanical testing
laboratories in England and Japan and, in addition, makes extensive use of
independent contract research firms. Extensive field testing is also conducted
through various arrangements with fleet operators and others.

                  Liaison offices in Detroit, Michigan; Hazelwood, England;
Hamburg, Germany; Tokyo, Japan; and Paris, France, maintain close contact with
the principal automotive and equipment manufacturers of the world and keep the
company abreast of the performance requirements for its products in the face of
changing technologies. These liaison activities also serve as contacts for
cooperative development and evaluation of products for future applications.
Contacts with the automotive and equipment industry are important so that the
company may have the necessary direction and lead time to develop products for
use in engines, transmissions, gear sets, and other areas of equipment that
require lubricants of advanced design.

                  PATENTS. The company owns a variety of United States and
foreign patents relating to lubricant and fuel additives, lubricants, chemical
compositions and processes, and protective coating materials and processes.
While such domestic and foreign patents expire from time to time, the company
continues to apply for and obtain patent protection on an ongoing basis.
Although the company believes that, in the aggregate, its patents constitute an
important asset, it does not regard its business as being materially dependent
upon any single patent or any group of related patents.

                  The company previously filed claims against Exxon Corporation
and its affiliates ("Exxon") relating to various commercial matters, including
alleged infringements by Exxon of certain of the company's patents. On October
12, 2000, the company reached a settlement of all pending patent litigation with
Imperial Oil Limited, a Canadian affiliate of Exxon Mobil Corporation. Further
information regarding litigation with Exxon is contained in Note 16 to the
Financial Statements, which is included in the company's 2000 Annual Report to
its shareholders, and is incorporated herein by reference.

                  ENVIRONMENTAL MATTERS. The company is subject to federal,
state and local laws and regulations designed to protect the environment and
limit manufacturing wastes and emissions. The company believes that as a general
matter its policies, practices and procedures are properly designed to prevent
unreasonable risk of environmental damage and the consequent financial liability
to the company. Compliance with the environmental laws and regulations requires
continuing management effort and expenditures by the company. Capital
expenditures for environmental projects were $2.6 million in 2000, which
represented 3.0% of 2000 capital expenditures. The company believes that the
cost of complying with environmental laws and regulations will not have a
material affect on the earnings, liquidity or competitive position of the
company.

                  The company is engaged in the handling, manufacture, use,
transportation and disposal of substances that are classified as hazardous or
toxic by one or more regulatory agencies. The company believes that its
handling, manufacture, use, transportation and disposal of such substances
generally have been in accord with environmental laws and regulations.

                  Among other environmental laws, the company is subject to the
federal "Superfund" law, under which the company has been designated as a
"potentially responsible party" that may be liable for cleanup costs associated
with various waste sites, some of which are on the U.S. Environmental Protection
Agency Superfund priority list. The company's experience, consistent with what
it believes to be the experience of others in similar cases, is that Superfund
site liability tends to be apportioned among parties based upon contribution of
materials to the Superfund site. Accordingly, the company measures its liability
and carries out its financial reporting responsibilities with respect to
Superfund sites based upon this standard, even though Superfund site liability
is technically joint and several in nature. The company views the expense of
such remedial cleanups as a part of its product cost, and accrues for estimated
environmental liabilities with charges to cost of sales. The company considers
its environmental accrual to be adequate to provide for its portion of costs for
all such known environmental liabilities. Based upon consideration of currently
available information, the company believes liabilities for environmental
matters will not have a material adverse affect on the company's financial
position, operating results or liquidity.

                  EMPLOYEES. At December 31, 2000, the company and its
subsidiaries had 4,390 employees of which approximately 54% were in the U.S.

                  INTERNATIONAL OPERATIONS. Financial information with respect
to domestic and foreign operations is contained in Note 12 to the Financial
Statements which is included in the company's 2000 Annual Report to its
shareholders, and is incorporated herein by reference.

                  The company supplies its additive customers abroad through
export from the United States and from overseas manufacturing plants. Sales and
technical service offices are maintained in more than 30 countries outside the
United States. As a result, the company is subject to business risks inherent in
non-U.S. activities, including political and economic uncertainty, import and
export limitations and market risk related to changes in interest rates and
foreign currency exchange rates. The company believes the political and economic
risks related to its foreign operations are mitigated due to the stability of
the countries in which its largest foreign operations are located.

                  While changes in the U.S. dollar value of foreign currencies
will affect earnings from time to time, the longer-term economic effect of these
changes should not be significant given the company's net asset exposure,
currency mix and use of U.S. dollar-based pricing in certain countries. The
company's consolidated net income will generally benefit as foreign currencies
increase in value compared to the U.S. dollar and will generally decline as
foreign currencies decrease in value.
