1.       The accompanying unaudited consolidated financial statements contain
         all adjustments (consisting only of normal recurring accruals unless
         otherwise noted) necessary to present fairly the financial position as
         of September 30, 2003 and December 31, 2002, and the results of
         operations and cash flows for the applicable periods ended September
         30, 2003 and 2002.

2.       Net income per share is computed by dividing net income by average
         common shares outstanding during the period, including contingently
         issuable shares. Net income per diluted share includes the dilutive
         effect resulting from outstanding stock options and stock awards.

         Per share amounts are computed as follows:

4.       The company aggregates its product lines into four principal operating
         segments: fluid technologies for transportation, fluid technologies for
         industry, advanced fluid systems and emulsified products. Fluid
         technologies for transportation (FTT) is comprised of additives for
         lubricating engine oils, such as for 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, this segment sells additive components and
         viscosity improvers within its lubricant and fuel additives product
         lines. The company's fluid technologies for transportation product
         lines are generally produced in shared manufacturing facilities and
         sold largely to a common customer base. Fluid technologies for industry
         (FTI) includes industrial additives, such as additives for hydraulic,
         grease and metalworking fluids and compressor lubricants; and
         performance chemicals, such as additives for coatings and inks,
         defoamers, process chemicals and surfactants for personal care and
         industrial cleaners. The advanced fluid systems and emulsified products
         operating segments do not constitute reportable business segments. The
         results of these two operating segments have been aggregated into the
         all other segment. Advanced fluid systems is comprised of fluid
         metering devices, particulate emission trap devices, and FluiPak(TM)
         sensor systems, and emulsified products is comprised of PuriNOx(TM)
         low-emissions diesel fuel.

         The company primarily evaluates performance and allocates resources
         based on segment contribution income, defined as revenues less expenses
         directly identifiable to the product lines aggregated within each
         segment, as well as projected future returns. In addition, in
         calculating segment operating profit before tax, the company allocates
         corporate research, testing, selling and administrative expenses,
         primarily based upon revenues, and assigns excess capacity costs to the
         segments to which it applies. The company calculates the cost of excess
         production capacity at our manufacturing facilities and excludes this
         amount from product costs when reporting segment gross profit and
         segment contribution income.

6.       In February 2003, the company notified employees at its Bromborough,
         England facility of plans to restructure and reduce operational costs
         to remain competitive. The facility consolidated various operational
         activities to achieve greater efficiency through improved business
         processes. There will be a reduction of 40 employees, or approximately
         35% of the facility's headcount, by the end of 2003. These changes
         began during the first quarter of 2003 and are expected to be completed
         by the end of 2003. As a result of these changes, the company recorded
         a restructuring charge for Bromborough of $.4 million in the third
         quarter and $6.7 million in the first nine months of 2003. The charge
         in the third quarter was primarily due to severance costs. The charge
         in the first nine months of 2003 consisted of $3.2 million in severance
         costs, $3.3 million in asset impairments and $.2 million in other
         miscellaneous costs. Cash expenditures in the third quarter of 2003
         were $.4 million and in the first nine months of 2003 were $2.9
         million. An accrued liability of $.5 million remains at September 30,
         2003, relating to employee severance costs. Additional severance costs
         of approximately $.3 million are expected to be incurred during the
         remainder of 2003 for those employees that will be separated after 90
         days of the legal notification date of the restructuring. The
         restructuring charge in the first nine months of 2003 also includes $.7
         million for a voluntary separation program to employees at the
         company's India joint venture, Lubrizol India Private Limited, which is
         accounted for using the consolidated method. Cash expenditures for
         India were $.7 million in both the second quarter and the first nine
         months of 2003. The charge for both cost reduction initiatives are
         reported as a

         On November 4, 2003 the company announced workforce reductions,
         primarily in the United States, designed to improve profitability to
         reposition the company for stronger growth. The reductions are expected
         to be completed by year-end, 2003 and are estimated to result in annual
         pretax savings of approximately $15 million beginning in 2004. These
         savings are in addition to approximately $4.5 million of pre-tax
         savings from the restructuring programs at Bromborough and India. The
         company will record a fourth quarter, 2003 restructuring charge that is
         projected to be approximately $13 million.

7.       The company has various financial instruments, including cash and
         short-term investments, investments in nonconsolidated companies,
         foreign currency forward contracts, commodity hedges, interest rate
         swaps and short- and long-term debt. The company has determined the
         estimated fair value of these financial instruments by using available
         market information and generally accepted valuation methodologies. The
         use of different market assumptions or estimation methodologies could
         have a material effect on the estimated fair value amounts. The company
         uses derivative financial instruments including interest rate and
         commodity hedges and forward foreign currency exchange contracts to
         manage market risks. The company does not use derivative financial
         instruments for trading purposes.

         The company recognizes all derivatives on the balance sheet at fair
         value and establishes criteria for designation and effectiveness of
         hedging relationships. Derivatives that are not hedges must be adjusted
         to fair value through income. Depending upon the nature of the hedge,
         changes in fair value of the derivative are either offset against the
         change in fair value of assets, liabilities or firm commitments through
         earnings or recognized in other comprehensive income until the hedged
         item is recognized in earnings. The ineffective portion of a
         derivative's change in value is immediately recognized in earnings.

         The company is exposed to the effect of changes in commodity prices for
         natural gas and electric utility expenses on its earnings and cash
         flow. In the second quarter of 2003, the company modified its commodity
         hedging program for natural gas and electricity purchasing by using
         financial instruments to reduce the volatility on earnings of utility
         expense. These contracts relate to transactions with maturities of less
         than one year and

                               September 30, 2003

         are accounted for as cash flow hedges and any effective unrealized
         gains or losses on open contracts are recorded in other comprehensive
         income, net of tax. At September 30, 2003 open contracts totaled $7.0
         million. A hedge liability was recorded at September 30, 2003 of $1.2
         million, which represents the unrealized loss at that date based upon
         current futures prices. The loss, net of deferred taxes of $.4 million,
         is included as a charge of $.8 million in other comprehensive income
         loss. The company expects all of the unrealized hedge gains or losses
         to be reclassified into earnings within the next 12 months.

8.       In the third quarter of 2003, the company completed two acquisitions in
         the fluid technologies for industry segment for cash of $67.5 million.
         In July, 2003 the company purchased the product lines of the North
         American-based silicones business from BASF, which expanded our foam
         control additives business to about $40 million in annual revenues.
         Assets acquired from BASF included customer lists, certain trademarks,
         manufacturing technology and other related intellectual property
         specifically developed for silicone products in the North America
         region, and finished goods inventory. Silicones are used in the
         manufacture of sealants, caulks and water proofing products. Historical
         annual revenues for these silicone products approximate $6 million. In
         late September, 2003 the company completed an acquisition of selected
         personal care ingredients business from Amerchol Corporation, a
         subsidiary of The Dow Chemical Company. Products from this business go
         into a wide range of end uses, including skin care and hair
         conditioners. Products include methyl glucoside derivatives, lanoline
         derivatives and Promulgen(TM) personal care ingredients. Annualized
         revenues of the acquisition are approximately $30 million.

         The company is currently in the process of allocating the purchase
         price for both of these acquisitions, so it is possible the assignment
         of value among assets acquired may change once the purchase price
         allocation is complete.

RESULTS OF OPERATIONS

Our revenues in the third quarter of 2003 were generally even with revenues in
the same period in 2002 and increased in the first nine months of 2003 compared
with the first nine months of 2002. However, net income decreased in both the
third quarter and first nine months of 2003 compared to the same periods in
2002. The primary operating drivers of the lower earnings were lower shipment
volume, higher average raw material cost and higher manufacturing expenses,
which more than offset a higher average selling price. A detailed discussion of
these and other factors that affected the third quarter and nine months follows.

We group our product lines into three reportable segments: fluid technologies
for transportation, fluid technologies for industry and all other. Fluid
technologies for transportation comprised approximately 76% of our consolidated
revenues and 86% of our segment pre-tax operating profits in the first nine
months of 2003. See Note 4 to the financial statements for further financial
disclosures by reporting segment.

Our consolidated revenues decreased $.4 million, or less than 1%, in the third
quarter of 2003 compared with the same period in 2002, due to a 10% decline in
shipment volume that was partially offset by a 9% increase in average selling
price. Excluding the impact of acquisitions (Dock Resins Corporation,
Intermountain Specialties, Inc., also known as Brose Chemical Company, and
certain product lines of BASF), third quarter revenues decreased $6.6 million,
or 1%, compared with the third quarter of the prior year. Consolidated revenues
increased $46.6 million, or 3%, in the first nine months of 2003 compared with
the same period in 2002, due to an 8% increase in average selling price,
partially offset by a 5% decline in shipment volume. Excluding the impact of
acquisitions (Kabo Unlimited, Inc., Dock, Chemron, Brose and certain product
lines of BASF), revenues increased $13.7 million, or 1%, in the first nine
months of 2003 compared with 2002, due to an 8% increase in average selling
price and higher revenues by our equipment companies, partially offset by an 8%
decline in shipment volume.

The following table shows our shipment volume by geographic zone in the third
quarter and the first nine months of 2003.

Excluding acquisitions, total shipment volume decreased 11% in the third quarter
of 2003 and 8% in the first nine months of 2003 compared with the same periods
in 2002. Approximately 9% of the decrease in the third quarter of 2003 and 25%
of the decrease in the first nine months of 2003 was due to a shift in our
viscosity modifier product line from liquids to a higher-value concentrated
solid form. All zones were affected by the shift to solid viscosity modifiers,
though the effects were mostly seen in North America and Europe. The remaining
shipment volume decrease for both periods was primarily due to losses associated
with a major international customer, which mainly affected North America and
Europe, along with weak worldwide demand for lubricants. We believe that the
severe acute respiratory syndrome (SARS) outbreak in Southeast Asia along with
weakness stemming from economic and political conditions within certain
countries of the Asia-Pacific / Middle East region contributed to the decline in
the Asia-Pacific / Middle East zone during the first nine months of 2003. See
the "Segment Analysis" section for additional explanation of shipment volume
variances by business segment and geographic zone in 2003 compared with 2002.

Our average additive selling price increased 9% in the third quarter of 2003
compared to the same period in 2002 due to a 6% increase in the combination of
price and product mix and 3% favorable currency effects. Our average additive
selling price increased 8% in the first nine months of 2003 compared to the
first nine months of 2002 equally due to favorable currency effects and an
increase in the combination of price and product mix. Sequentially, the third
quarter 2003 average additive selling price was even with the second quarter and
3.5% higher than the first quarter of 2003, due to favorable currency effects
and the implementation of a price increase in the form of a surcharge at the end
of the first quarter of 2003. This surcharge was designed to cover the
continuing rise in raw material prices and natural gas-fired utility costs,
since our last price increase in the fourth quarter of 2002.

Our cost of sales increased $18.6 million, or 5% ($14.4 million, or 4%,
excluding acquisitions), in the third quarter of 2003 and $66.5 million, or 6%
($43.2 million, or 4%, excluding acquisitions), in the first nine months of 2003
compared with the same periods in 2002. The increase for both periods was
primarily due to higher average raw material cost and higher manufacturing
expenses. Average raw material cost increased 11% in the third quarter of 2003
and 9% in the first nine months of 2003 compared with the same periods of 2002
primarily due to higher raw material prices, mainly driven by higher prices of
crude oil and natural gas, and unfavorable currency effects. Sequentially,
average raw material cost in the third quarter of 2003 increased 2% from the
second quarter of 2003.

                Item 2 - Management's Discussion and Analysis of
                  Financial Condition and Results of Operations

Total manufacturing expenses increased 15% (14% excluding acquisitions) in the
third quarter of 2003 and 13% (11% excluding acquisitions) in the first nine
months of 2003 compared with the same periods in 2002. We built inventories in
the third quarter of 2002 and drew down inventories in the third quarter of
2003. Excluding acquisitions and the impact of changes in inventory levels,
manufacturing expenses increased 7% in the third quarter of 2003 and 10% in the
first nine months of 2003 compared with the same periods in 2002, primarily due
to unfavorable currency effects, higher utilities and higher salary and benefit
expenses, partially offset by a reduction in variable pay expense. In addition,
total manufacturing expenses included a reclassification of expenses at certain
subsidiaries of our fluid technologies for industry (FTI) and advanced fluid
systems (AFS) operating segments that were charged in 2002 to selling and
administrative expenses or material costs. The reclassification increased
manufacturing expenses by $.9 million in the third quarter of 2003 and $3.6
million in the first nine months of 2003. We estimate the total impact of this
reclassification to manufacturing expenses for 2003 will be approximately $5.0
million.

Cost of sales for the first nine months of 2003 included approximately $3
million in manufacturing expenses to cover costs associated with two fires that
occurred during the second quarter of 2003. In April 2003, an
after-working-hours fire destroyed a metalworking additive blending facility we
leased in Detroit. There were no injuries, nor any damage to a nearby warehouse
where we stored finished goods. We were able to supply customers from this
warehouse and we have permanently shifted production to our Painesville, Ohio
plant. Also in April 2003, a fire associated with a maintenance shutdown
occurred in a dispersant production unit at our plant in Le Havre, France.

Gross profit (net sales less cost of sales) decreased $19.0 million, or 13%
($21.0 million, or 14%, excluding acquisitions), in the third quarter of 2003
and $19.8 million, or 5% ($29.3 million, or 7%, excluding acquisitions), in the
first nine months of 2003 compared with the same periods in 2002. The decrease
for both periods was primarily due to lower shipment volume, higher average raw
material cost and higher manufacturing expenses, partially offset by higher
average selling price. Our gross profit percentage (gross profit divided by net
sales) decreased to 25.9% for the third quarter of 2003 and 26.9% for the first
nine months of 2003, compared with 29.6% in the third quarter of 2002 and 29.1%
in the first nine months of 2002. The decrease in the gross profit percentages
for both periods was due to the reasons previously described. The impact of
acquisitions and the reclassification of certain expenses to manufacturing, as
described above, accounted for a decrease of 60 basis points (of the total 220
basis point decline) in our gross profit percentage in the first nine months of
2003. Sequentially, the gross profit percentage decreased from 27.5% in the
second quarter of 2003.

Our selling and administrative expenses decreased $.9 million, or 2% ($1.5
million, or 3%, excluding acquisitions), in the third quarter of 2003 and
increased $2.9 million, or 2% (decreased $.1 million excluding acquisitions), in
the first nine months of 2003 compared with the same periods in 2002. Excluding
acquisitions, the decrease for both periods was primarily due to a reduction in
our variable pay expense and the reclassification of certain 2002 selling and
administrative expenses for our FTI and AFS operating segments, which was
partially offset by unfavorable currency effects and higher salary and benefit
expenses.

Our research, testing and development expenses (technology expenses) decreased
$1.8 million, or 4% ($2.1 million, or 5%, excluding acquisitions), in the third
quarter of 2003 and $1.4 million, or 1% ($2.7 million, or 2%, excluding
acquisitions), in the first nine months of 2003 compared with the same periods
in 2002. The decrease for both periods, excluding acquisitions, was due to

                Item 2 - Management's Discussion and Analysis of
                  Financial Condition and Results of Operations

lower testing at outside laboratories and a reduction in our variable pay
expense, partially offset by unfavorable currency effects. In addition,
technology expenses included a write-down of $1.1 million in the first nine
months of 2003 related to a former technical facility in Japan that we sold
during the third quarter of 2003.

In the first nine months of 2003, we recorded a restructuring charge of $7.4
million, or $.10 per share, consisting of $6.7 million for our Bromborough,
England intermediate production and blending facility and $.7 million for a
voluntary separation program at our joint venture in India. The Bromborough
charge primarily consisted of $3.2 million in employee separation benefits and
$3.3 million in asset impairments for production units taken out of service. In
the third quarter the Bromborough charge was $.4 million, or $.01 per share, for
severance costs. We have eliminated some capacity at this facility and have
planned a reduction of 40 positions. We expect the Bromborough restructuring
initiative will be completed by year-end. We estimate the full year
restructuring charge will be approximately $7.5 million, or $.10 per share, and
total annualized savings from the combined restructuring activities are
projected to be $4.5 million, of which approximately $2.0 million is expected to
be realized in 2003.

The change in other income (expense) favorably affected pre-tax income by $.5
million in the third quarter of 2003 and $4.2 million in the first nine months
of 2003 compared with the same periods in 2002. The favorable variance for the
first nine months of 2003 was primarily due to increased currency translation
gains.

Interest income decreased $.9 million in the third quarter of 2003 and $2.0
million in the first nine months of 2003 compared with the same periods in 2002
as a result of lower interest rates. Interest expense increased $.8 million in
the third quarter of 2003 and $1.7 million in the first nine months of 2003,
compared with the same periods in 2002, due to the absence of the interest rate
swap agreements that we utilized in the third quarter of 2002 and, in the third
quarter of 2003, interest on a European tax settlement. In 2002, we had swap
agreements that reduced interest expense by approximately $.8 million ($.3
million impact from outstanding swap and $.5 million amortization of deferred
gain) in the third quarter of 2002 and $3.6 million ($3.1 million impact from
outstanding swap and $.5 million amortization of deferred gain) in the first
nine months of 2002. As a result of the interest rate swap agreements that were
terminated in 2002, the unrecognized gain is being amortized as a reduction of
interest expense through December 1, 2008. Amortization of the unrealized gain
reduced interest expense in the third quarter of 2003 by approximately $.7
million and in the first nine months of 2003 by approximately $2.0 million.

As a result of the above factors, our income before income taxes and the
cumulative effect of a change in accounting principle decreased 35% to $34.0
million in the third quarter of 2003, and 20% to $115.5 million in the first
nine months of 2003, compared with $52.1 million and $144.0 million for the
respective corresponding periods in 2002.

We had an effective tax rate of 28.6% for the third quarter of 2003 and 31.0%
for the first nine months of 2003, compared with 30.0% for both periods in 2002.
The lower effective tax rate in the third quarter of 2003 increased earnings by
$.01 per share and the higher effective tax rate for the first nine months of
2003 reduced earnings by $.03 per share, compared to the same periods in 2002.
The increase in the effective tax rate for the first nine months of 2003, as
compared to the first nine months of 2002, mainly was due to a non-recurring
2002 charitable contribution of technology, offset in part by the impact of
higher expected levels of non-taxable currency translation gains.

                Item 2 - Management's Discussion and Analysis of
                  Financial Condition and Results of Operations

We lowered our estimated 2003 effective tax rate in both the second quarter and
the third quarter, mainly due to higher expected levels of non-taxable currency
translation gains for the full year.

As a result of the factors described above, income before the cumulative effect
of a change in accounting principle decreased $12.2 million, or 33% in the third
quarter of 2003 and $21.1 million, or 21%, in the first nine months of 2003
compared with the same periods in 2002. Income per share, before the cumulative
effect of a change in accounting principle, was $.47 in the third quarter of
2003 and $1.54 in the first nine months of 2003, compared with $.71 and $1.96
for the respective corresponding periods in 2002.

During the first half of 2002, we completed the impairment analysis required for
Statement of Financial Accounting Standards 142 (SFAS 142), "Goodwill and Other
Intangible Assets," which we adopted on January 1, 2002. There was no impairment
either in the fluid technologies for transportation segment or in the fluid
technologies for industry operating segment. However, for the advanced fluid
systems operating segment, which is included in the all other reporting segment,
we recorded an impairment of $7.8 million, thus eliminating all the goodwill for
the all other reporting segment. The charge was recorded as a cumulative effect
of a change in accounting principle as of January 1, 2002.

Primarily as a result of the above factors, our net income in the third quarter
of 2003 decreased 33% to $24.3 million ($.47 per share), compared with $36.5
million ($.71 per share) in the third quarter of 2002. Net income in the first
nine months of 2003 decreased 14% to $79.7 million ($1.54 per share) compared
with $93.0 million ($1.81 per share) in the first nine months of 2002.

On November 4, 2003 the company announced workforce reductions, primarily in the
United States, designed to improve profitability to reposition the company for
stronger growth. The reductions are expected to be completed by year-end, 2003
and are estimated to result in annual pretax savings of approximately $15
million beginning in 2004. These savings are in addition to approximately $4.5
million of pre-tax savings from the restructuring programs at Bromborough and
India. The company will record a fourth quarter, 2003 restructuring charge that
is projected to be approximately $13 million.

Fluid Technologies for Transportation Segment

Segment revenues decreased $18.4 million, or 5%, in the third quarter of 2003
compared with the same period in 2002, due to a 13% decline in shipment volume,
partially offset by an 8% increase in average selling price. The increase in
average selling price for the third quarter of 2003 primarily was due to an
increase in the combination of price and product mix along with 3% favorable
currency effects. Segment revenues decreased $21.4 million, or 2%, in the first
nine months of 2003 compared with the first nine months of 2002 due to a 10%
decrease in shipment volume partially offset by an 8% increase in average
selling price. The increase in average selling price in the first nine months of
2003 primarily was due to favorable currency effects of 5% and the remainder was
due to an increase in the combination of price and product mix.

The fluid technologies for transportation segment implemented a price increase
in December 2002 for the North America zone and in January 2003 for the rest of
the world. In addition, a second price increase that was structured as a
surcharge was implemented in late March for North America and in late April for
products sourced from Asia and Latin America as well as select products in
Europe. This surcharge was designed to cover the continuing rise in raw material
prices and natural gas-fired utility costs, since our last price increase in the
fourth quarter of 2002.

The shipment volume decline in both the third quarter and the first nine months
of 2003 partially was due to lower unit sales of viscosity modifiers,
principally caused by a shift from liquid polymers to solid polymers. Generally,
solids are one-tenth the volume of liquids. Excluding this shift in our
viscosity modifier product line, total shipment volume decreased 12% in the
third quarter and 8% in the first nine months of 2003. About half of the
shipment volume decreases in North America and Europe were due to losses in our
engine oils business and specialty driveline business associated with a major
international customer. The declines in North America for the third quarter and
the first nine months of 2003 also were due to our shifting of some products in
our specialties business to more concentrated formulations. In addition, weak
worldwide demand for lubricants contributed to the declines in the North America
and Europe zones for both the third quarter and the first nine months of 2003.
The third quarter decrease in Asia-Pacific/Middle East volume primarily was due
to the weak business environment stemming from economic and political conditions
in certain parts of this region. During the first nine months of 2003, we
believe SARS also negatively impacted business activity primarily in the
Asia-Pacific / Middle East zone.

Segment gross profit decreased $19.2 million, or 16%, in the third quarter of
2003 and $23.0 million, or 6%, in the first nine months of 2003 compared with
the same periods in 2002. The decrease for both periods primarily was due to
lower shipment volume, higher average raw material cost and higher manufacturing
expenses, partially offset by higher average selling price due to favorable
currency effects and an increase in the combination of price and product mix. In
calculating gross profit at the operating segment level, we exclude our estimate
of the cost of excess capacity from product costs (See Note 4 to the financial
statements.) The gross profit percentage for this segment was 27.4% in the third
quarter of 2003 and 28.8% in the first nine months of 2003, compared with 30.9%
and 30.2% in the respective comparable periods in 2002. The decrease in the
gross profit percentage for both comparison periods was due to the reasons
previously explained.

Direct selling, marketing and technical expenses were flat in the third quarter
of 2003 and decreased $3.3 million, or 3%, in the first nine months of 2003
compared with the same periods in 2002, primarily due to lower technical
spending at outside test laboratories. Segment contribution income decreased
$19.1 million, or 23%, in the third quarter of 2003 compared with the third
quarter of 2002 entirely due to lower gross profit. Segment contribution income
decreased $20.8 million, or 9%, in the first nine months of 2003 compared with
the same period in 2002 as a result of lower gross profit and lower equity
earnings, partially offset by lower technical expenses.

Fluid Technologies for Industry Segment

Segment revenues increased $15.2 million, or 15% ($8.9 million, or 9%, excluding
acquisitions), in the third quarter of 2003 and $62.1 million, or 22% ($29.2
million, or 10%, excluding acquisitions), in the first nine months of 2003
compared with the same periods in 2002. Acquisitions contributed $6.2 million of
the segment revenue increase in the third quarter of 2003, due to Dock Resins,
Brose and the product lines of BASF, and $32.9 million of the segment revenue
increase in the first nine months of 2003, primarily due to Dock Resins and
Chemron. The 9% increase in segment revenues during the third quarter of 2003,
excluding acquisitions, was due to a 5% increase in shipment volume along with a
4% increase in average selling price compared to the third quarter of 2002. The
10% increase in segment revenues during the first nine months of 2003, excluding
acquisitions, was primarily due to a 9% increase in shipment volume.

The shipment volume increase in both periods primarily was due to ongoing
business growth as the result of new business gains and the introduction of new
products in our personal care, defoamers, specialty monomers and mining
chemicals businesses. The third quarter increase in average selling price
primarily was due to 3% favorable currency effects and a slight increase in the
combination of price and product mix, partially due to favorable product mix in
our personal care business. Average selling price increased 1% for the first
nine months of 2003 compared with the same period in 2002, due to 4% favorable
currency effects partially offset by a decrease in the combination of price and
product mix. The decrease occurred in our inks additives business, specialty
monomers business and compressor lubricant business and primarily was due to
lower priced product mix. Slightly higher royalty income in our synthetic
refrigerant lubricants business of $.1 million in the third quarter of 2003 and
$.5 in the first nine months of 2003, compared with the same periods in 2002,
also contributed to the increased segment revenues.

the third quarter and first nine months of 2003 compared with the same periods
in 2002.

Excluding acquisitions, the increase in the third quarter of 2003 for North
America and Europe primarily was due to increases in the coatings and inks
business. The shipment volume increase in North America in the first nine months
of 2003 primarily was due to the 2002 acquisitions of Chemron and Dock Resins.
Excluding acquisitions, the increase in North America in the first nine months
of 2003 partially was due to market share gains in our personal care and
compressor lubricant businesses along with increases in the coatings and inks
business from the introduction of new products. The increase in Europe in the
first nine months of 2003 was related to increases in our metalworking and
compressor lubricant businesses and new applications in our specialty monomers
business. The increase in the third quarter of 2003 for the Asia-Pacific /
Middle East zone was spread across many of the FTI businesses. Approximately

half of the increase in the first nine months of 2003 for Asia-Pacific / Middle
East was due to increased shipments in our metalworking business as a result of
a distributor relationship that was terminated at the beginning of 2002. Our
metalworking sales in this zone in the first half of 2002 were below normal
levels because our customers were buying from the distributor's inventory. Our
customers subsequently resumed purchasing the products from us, beginning in the
second half of 2002. The increase in Latin America in both the third quarter of
2003 and the first nine months of 2003 was due to a shift of our specialty
emulsifiers business with some of our existing customers from North America to
Latin America along with some business gains in our coatings and inks business.

Segment gross profit increased $2.1 million, or 6% ($.1 million, or less than
1%, excluding acquisitions), in the third quarter of 2003, and $8.6 million, or
9% ($.9 million decrease, or 1%, excluding acquisitions), in the first nine
months of 2003 compared with the same periods in 2002. Excluding acquisitions,
the third quarter increase was due to higher shipment volume that was partially
offset by higher manufacturing expenses. The increase in manufacturing expenses
primarily was due to the reclassification to manufacturing expenses of $.9
million in FTI expenses charged in 2002 as selling and administrative expenses,
and costs associated with the integration of a multi-purpose chemical production
facility in Spartanburg, South Carolina that was purchased in the second quarter
of 2003. In addition, unfavorable product mix in the anti-wear hydraulics
business lowered segment gross profit in the third quarter of 2003. Excluding
acquisitions, the decrease in segment gross profit in the first nine months of
2003 was due to higher manufacturing expenses and higher average raw material
cost, which more than offset higher shipment volume and higher average selling
price. The increase in manufacturing expenses primarily was due to the
reclassification to manufacturing expenses of $3.6 million of FTI expenses
charged in 2002 as selling and administrative expenses, and costs relating to
the fire at the Detroit manufacturing facility. The gross profit percentage for
this segment was 30.6% in the third quarter of 2003 and 33.1% in the first nine
months of 2003, compared with 30.6% and 34.3% in the respective corresponding
periods in 2002. The decrease in the gross profit percentage for the first nine
months of 2003 compared with the same period in 2002 was due to the impact of
the Chemron acquisition, higher raw material costs and increased manufacturing
expenses as a result of the metalworking fire and the reclassification of
certain FTI selling and administrative expenses to manufacturing expenses.

Segment contribution income increased $.1 million, or less than 1%, in the third
quarter of 2003 and increased $1.9 million, or 4%, in the first nine months of
2003 compared with the same periods in 2002. The increase for both periods
primarily was due to higher gross profit, partially offset by higher direct
technical and selling expenses and higher amortization expenses resulting from
2002 acquisitions.

WORKING CAPITAL, LIQUIDITY AND CAPITAL RESOURCES

Cash provided by operating activities was $113.7 million in the first nine
months of 2003 compared with $173.2 million in the first nine months of 2002.
The decrease in cash from operating activities of $59.5 million in the first
nine months of 2003 primarily was due to lower earnings and an increase in
working capital items. Increased receivables consumed cash of $18.8 million,
partially due to fire insurance receivables in 2003 of approximately $5.0
million to reimburse the company for expenditures associated with the fire. In
addition, average days sales outstanding in the first nine months of 2003 were
54.5 days, compared with 53.5 days in the first nine months of 2002. Increased
inventory consumed cash of $13.3 million, due to higher unit values, some
slowing of sales and a build-up of strategic stock in certain key materials to
ensure customers of supply and to protect them during planned maintenance
shutdowns. We paid down accounts payable and accrued liabilities by $24.3

million since year-end compared with a build up of $4.7 million in the first
nine six months of 2002, due to the timing of procurement and payment to
vendors. We have not changed our payment terms to suppliers.

Our capital expenditures in the first nine months of 2003 were $59.5 million,
compared with $46.0 million for same period in 2002. In 2003, we estimate
capital expenditures will be in the range of $80 million to $90 million as
compared with $65.3 million in 2002. Capital expenditures included the purchase
of a multipurpose chemical production facility in Spartanburg, South Carolina
with additional adjacent land in April 2003 for $2.8 million. The facility is
capable of producing several products used in a variety of applications for the
fluid technologies for industry segment.

We completed two acquisitions in the third quarter of 2003 for $67.5 million. In
July, 2003 we purchased the product lines of the North American-based silicones
business from BASF, which expands our foam control additives business to about
$40 million in annual revenues. Assets acquired from BASF's North American-based
silicones business included customer lists, certain trademarks, manufacturing
technology and other related intellectual property specifically developed for
silicone products in the North America region, and finished goods inventory.
Silicones are used in the manufacture of sealants, caulks and water proofing
products. Historical annual revenues for these silicone products approximate $6
million. In late September, 2003 we completed an acquisition of selected
personal care ingredients business from Amerchol Corporation, a subsidiary of
The Dow Chemical Company. Products from this business go into a wide range of
end uses, including skin care and hair conditioners. Products include methyl
glucoside derivatives, lanoline derivatives and Promulgen(TM) personal care
ingredients. Historical annualized revenues of this acquisition approximate $30
million.

Our net debt to capitalization ratio at September 30, 2003 was 18.0%. Net debt
is the total of short- and long-term debt, reduced by cash and short-term
investments in excess of an assumed operating cash level of $40 million and
excluding unrealized gains and losses on derivative instruments designated as
fair value hedges of fixed rate debt. Capitalization is shareholders' equity
plus net debt. Total debt as a percent of capitalization was 28.9% at September
30, 2003.

Our share repurchase program has been suspended indefinitely as we are holding
our financial resources in reserve for future acquisitions. Primarily as a
result of all of the above activities and the payment of dividends, our balance
of cash and short-term investments decreased $51.3 million at September 30, 2003
compared with December 31, 2002.

We made a U.S. pension contribution for the 2002 plan year of approximately $3.6
million late in September 2003. We also anticipate making a 2003 plan year
contribution of approximately $3.0 million in September 2004. This latter amount
may change depending on asset and liability valuations as of year end.

Our financial position remains strong with a ratio of current assets to current
liabilities of 3.1 to 1 at September 30, 2003, compared with 3.0 to 1 at
December 31, 2002. We currently have $350 million of committed revolving credit
facilities that will expire in July 2006. We had an additional $175 million of
committed revolving credit facilities that expired in July 2003, which we chose
not to renew. We believe our existing credit facilities, internally generated
funds and ability to obtain additional financing, if desired, will be sufficient
to meet our future capital needs, including acquisitions to expand into new and
existing fluid technology markets.

                Item 2 - Management's Discussion and Analysis of
                  Financial Condition and Results of Operations

In the second quarter of 2003, we modified our commodity hedging program for
natural gas and electricity purchases by using financial instruments. These
contracts are accounted for as cash flow hedges and any effective unrealized
gains or losses on open contracts are recorded in other comprehensive income,
net of tax. At September 30, 2003, open contracts totaled $7.0 million.
Maturities ranged from one to twelve months. A hedge liability was recorded at
September 30, 2003 of $1.2 million, which represented the unrealized loss at
that date based upon current future prices as of that date. The loss, net of
deferred taxes of $.4 million, was included as a charge of $.8 million in other
comprehensive income loss.

CAUTIONARY STATEMENT FOR SAFE HARBOR PURPOSES

This Management's Discussion and Analysis of Financial Condition and Results of
Operations contains forward-looking statements within the meaning of the federal
securities laws. As a general matter, forward-looking statements are those
focused upon future plans, objectives or performance as opposed to historical
items and include statements of anticipated events or trends and expectations
and beliefs relating to matters not historical in nature. Such forward-looking
statements are subject to uncertainties and factors relating to our operations
and business environment, all of which are difficult to predict and many of
which are beyond our control. These uncertainties and factors could cause our
actual results to differ materially from those matters expressed in or implied
by such forward-looking statements.

We believe that the following factors, among others, could affect our future
performance and cause our actual results to differ materially from those
expressed or implied by forward-looking statements made in this quarterly
report:

-    the overall demand for lubricant and fuel additives on a worldwide basis,
     which has a slow growth rate in mature markets such as North America and
     Europe;

-    the effect on our business resulting from economic and political
     uncertainty within the Asia-Pacific, Middle East and Latin American
     regions;

-    the lubricant additive demand in developing regions such as China and
     India, which geographic zones are an announced focus of our activities;

-    the potential negative impact on product pricing and shipment volume demand
     from the consolidation of finished lubricant marketers;

-    the degree of competition resulting from lubricant additive industry
     overcapacity;

-    technology developments that affect longer-term trends for lubricant
     additives, such as improved equipment design, fuel economy, longer oil
     drain intervals, alternative fuel powered engines and emission system
     compatibility;

-    the overall global economic environment, which affects the operating
     results of fluid technologies for industry in particular;

-    the extent to which we are successful in expanding our business in new and
     existing fluid technology markets incorporating chemicals, systems and
     services for industry and transportation;

-    our ability to identify, complete and integrate acquisitions for profitable
     growth;

-    our success at continuing to develop proprietary technology to meet or
     exceed new industry performance standards and individual customer and
     original equipment manufacturers' expectations;

-    the frequency of change in industry performance standards, which affects
     the level and timing of our technology costs, the product life cycles and
     the relative quantity of additives required for new specifications;

     petroleum-based products;

-    the cost and availability of energy, including natural gas and electricity;

-    the effects of fluctuations in currency exchange rates upon our reported
     results from international operations, together with non-currency risks of
     investing in and conducting significant operations in foreign countries,
     including those relating to political, social, economic and regulatory
     factors;

-    the extent to which we achieve market acceptance of our PuriNOx(TM)
     low-emission, water-blend fuel product;

-    significant changes in government regulations affecting environmental
     compliance.

                            THE LUBRIZOL CORPORATION

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

         We operate manufacturing and blending facilities, laboratories and
         offices around the world and utilize fixed and variable rate debt to
         finance our global operations. As a result, we are subject to business
         risks inherent in non-U.S. activities, including political and economic
         uncertainties, import and export limitations, and market risks related
         to changes in interest rates, commodity prices and foreign currency
         exchange rates. We believe the political and economic risks related to
         our foreign operations are largely mitigated due to the stability of
         the countries in which our largest foreign operations are located.

         In the normal course of business, we use derivative financial
         instruments including interest rate and commodity hedges and forward
         foreign currency exchange contracts to manage our market risks. Our
         objective in managing our exposure to changes in interest rates is to
         limit the impact of such changes on earnings and cash flow and to lower
         our overall borrowing costs. Our objective in managing our exposure to
         changes in foreign currency exchange rates is to reduce volatility of
         our earnings and cash flow associated with such changes. Our principal
         currency exposures are the euro, the pound sterling, the Japanese yen
         and certain Latin American currencies. Our objective in managing our
         exposure to changes in commodity prices is to reduce the volatility on
         earnings of utility expense. We do not purchase derivatives for trading
         purposes.

         Our primary commodity hedge exposures relate to natural gas and
         electric utility expenses. The calculation of potential loss in fair
         value is based on an immediate change in the U.S. dollar equivalent
         balances of our commodity exposures due to a 10% shift in the
         underlying commodity prices. The potential loss in cash flow and income
         before tax is based on the change in cash flow and income before tax
         over a one-year period resulting from an immediate 10% change in
         commodity prices. A hypothetical 10% increase in commodity prices for
         the first nine months of 2003 would have had a favorable impact and a
         hypothetical 10% decrease in commodity prices would have had an
         unfavorable impact on fair value of $.6 million, cash flow of $.6
         million, and income before tax of $.6 million in 2003.

         A quantitative and qualitative discussion about our market risk is
         contained on page 21 of our 2002 Annual Report to our shareholders.
         There have been no material changes in the market risks faced by us
         since December 31, 2002.

Item 4.  Controls and Procedures

         We carried out an evaluation, under the supervision and with the
         participation of our chief executive officer and chief financial
         officer, of the effectiveness of our disclosure controls and procedures
         (as defined in Exchange Act Rule 13a-15(e)) as of September 30, 2003.
         Based on that evaluation, our chief executive officer and chief
         financial officer concluded that, as of September 30, 2003, our
         disclosure controls and procedures are effective in timely alerting
         them to material information relating to the company and its
         consolidated subsidiaries required to be included in our periodic SEC
         filings. There were no significant changes in our internal control over
         financial reporting that occurred during the third quarter of 2003 that
         has materially affected, or is reasonably likely to materially affect,
         our internal control over financial reporting.
