Notes to Consolidated Financial Statements
March 31, 2005

1. BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements have been prepared
in accordance with generally accepted accounting principles for interim
financial information and Article 10 of Regulation S-X. Accordingly, they do not
include all of the information and footnotes required by generally accepted
accounting principles for complete financial statements. In the opinion of
management, all adjustments (consisting of normal recurring accruals unless
otherwise noted) considered necessary for a fair presentation have been
included. Operating results for the three months ended March 31, 2005 are not
necessarily indicative of the results that may be expected for the year ending
December 31, 2005.

The balance sheet at December 31, 2004 has been derived from the audited
financial statements at that date but does not include all of the information
and footnotes required by accounting principles generally accepted in the United
States for complete financial statements.

2. SIGNIFICANT ACCOUNTING POLICIES

NET INCOME PER SHARE

Net income per share is computed by dividing net income by the weighted-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:

===== =====


Weighted-average shares issuable upon the exercise of stock options that were
excluded from the diluted earnings per share calculations because they were
antidilutive for the three months ended March 31, 2004 were 1.9 million.

STOCK-BASED COMPENSATION

The company has elected the intrinsic value method to account for employee stock
options. The following table shows the pro forma effect on net income per share
if the company had applied the fair value recognition provisions of the
Financial Accounting Standards Board's (FASB) Statement of Financial Accounting
Standard (SFAS) No. 123, "Accounting for Stock-Based Compensation," to
stock-based employee compensation.

NEW ACCOUNTING STANDARDS

In March 2005, the FASB issued Interpretation (FIN) No. 47, "Accounting for
Conditional Asset-Retirement Obligations." This standard codifies SFAS No. 143,
"Asset-Retirement Obligations," and states that companies must recognize a
liability for the fair value of a legal obligation to perform asset-retirement
obligations that are conditional on a future event if the amount can be
reasonably estimated. Specifically, FIN No. 47 provides additional guidance on
whether the fair value is reasonably estimable. FIN No. 47 is effective for the
company starting January 1, 2006. The company does not believe the adoption of
this standard will have a material impact on its financial position, results of
operations or cash flows.

In December 2004, the FASB issued SFAS No. 123(R), "Share-Based Payment." This
standard will require compensation costs related to share-based payment
transactions to be recognized in the financial statements. With limited
exceptions, the amount of compensation cost will be measured based on the
grant-date fair value of the equity or liability instruments issued. In
addition, liability awards will be remeasured each reporting period.
Compensation cost will be recognized over the period that an employee provides
service in exchange for the award. This standard replaces SFAS No. 123 and
supersedes Accounting Principles Board (APB) Opinion No. 25, "Accounting for
Stock Issued to Employees," and applies to all awards granted, modified,
repurchased or cancelled after July 1, 2005. In April 2005, the Securities and
Exchange Commission (SEC) amended the compliance date of SFAS No. 123(R) through
an amendment of Regulation S-X. The new effective date for the company is
January 1, 2006. The company is currently evaluating the provisions of this
standard to determine the impact on its consolidated financial statements. It
is, however, expected to reduce consolidated net income.

In December 2004, the FASB issued SFAS No. 153, "Exchanges of Nonmonetary
Assets." This standard amended APB Opinion No. 29, "Accounting for Nonmonetary
Transactions," to eliminate the exception from fair-value measurement for
nonmonetary exchanges of similar productive assets. This standard replaces this
exception with a general exception from fair-value measurement for exchanges of
nonmonetary assets that do not have commercial substance. A nonmonetary exchange
has no commercial substance if the future cash flows of the entity are expected
to change significantly as a result of the exchange. This statement is effective
for all nonmonetary asset exchanges completed by the company starting January 1,
2006. The company does not believe the adoption of this standard will


-7-

THE LUBRIZOL CORPORATION
Notes to Consolidated Financial Statements
March 31, 2005

have a material impact on its financial position, results of operations or cash
flows.

In November 2004, the FASB issued SFAS No. 151, "Inventory Costs," to clarify
the accounting for abnormal amounts of idle facility expense, freight, handling
costs and wasted material. This standard requires that such items be recognized
as current-period charges. The standard also establishes the concept of "normal
capacity" and requires the allocation of fixed production overhead to inventory
based on the normal capacity of the production facilities. Any unallocated
overhead must be recognized as an expense in the period incurred. This standard
is effective for inventory costs incurred starting January 1, 2006. The company
does not believe the adoption of this standard will have a material impact on
its financial position, results of operations or cash flows.

RECLASSIFICATIONS

Certain reclassifications have been made to the 2004 financial statements to
conform to the 2005 presentation.

USE OF ESTIMATES

The preparation of consolidated financial statements in conformity with
accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts of assets and liabilities and disclosure of contingent assets and
liabilities at the date of the financial statements and the reported amounts of
revenues and expenses during the reporting period. Actual results could differ
from those estimates.

3. ACQUISITIONS AND PRO FORMA FINANCIAL INFORMATION

On June 3, 2004, we completed the acquisition of Noveon International, Inc.
(Noveon International) for cash of $920.2 million (inclusive of $32.9 million in
certain seller expenses) plus transaction costs of $11.4 million and less cash
acquired of $103.0 million. In addition, the company assumed $1,103.1 million of
long-term indebtedness from Noveon International. With the acquisition of Noveon
International, the company has accelerated its program to attain a substantial
presence in the personal care and coatings markets by adding a number of
higher-growth, industry-leading products under highly recognizable brand names,
including Carbopol(R), to the company's portfolio of lubricant and fuel
additives, and consumer products. Additionally, Noveon International has a
number of industry-leading specialty materials businesses, including TempRite(R)
chlorinated polyvinyl chloride and Estane(R) thermoplastic polyurethane.

The acquisition and related costs were initially financed with the proceeds of a
$2,450.0 million 364-day bridge credit facility. Shortly after the acquisition,
the company repaid substantially all of the assumed long-term debt of Noveon
International with proceeds of the temporary bridge loan. In addition, the
temporary bridge loan was repaid in full in September 2004 with the proceeds
from the permanent financing obtained by the issuance of senior notes,
debentures, bank term loans and equity.

Our consolidated balance sheet as of March 31, 2005 reflects the acquisition of
Noveon International under the purchase method of accounting. We recorded the
various assets acquired and liabilities assumed, primarily working capital
accounts, of Noveon International at their estimated fair values determined as
of the acquisition date. The allocation of the purchase price has not yet been
finalized, but is substantially complete, as of March 31, 2005. While the
company does not expect any material changes, the purchase price allocation
remains subject to revision through the end of the allocation period in the
second quarter of 2005. Actuarial valuations were completed for the projected
pension and other post-employment benefit obligations and were reflected in the
purchase price allocation. Appraisals of long-lived assets and identifiable
intangible assets, including an evaluation of in-process research and
development (IPR&D) projects, were also obtained. Although substantially
complete, management's evaluation of these appraisals is not yet final. The
company is still evaluating the impact of information obtained during the
allocation period from the due diligence procedures performed relating to
certain businesses and assets considered for

Notes to Consolidated Financial Statements

divestiture. In connection with the acquisition of Noveon International, the
company has targeted non-core businesses with total revenues of approximately
$300.0 million to $500.0 million for disposition. This plan was contemplated at
the time of acquisition and plan activities have been underway since the fourth
quarter of 2004. The company is also still in the process of finalizing its
reconciliation of the underlying fixed-asset records to the respective
valuations. As a result of both of these efforts, in the first quarter 2005, the
company reduced the amount allocated to property, plant and equipment by $43.9
million. The goodwill associated with the transaction increased accordingly.
Depreciation expense for the three months ended March 31, 2005 includes a
related adjustment for $1.2 million representing the cumulative impact of the
change in the estimated fair values assigned to property, plant and equipment.

The purchase price included the estimated fair value of IPR&D projects totaling
$34.0 million that, as of the acquisition date, had not yet reached
technological feasibility and had no alternative future use. As a result, the
full amount allocated to IPR&D was expensed in 2004. There have been no changes
to the valuation of IPR&D in 2005. The inventory step-up to fair value totaled
$24.2 million, of which $9.8 million was expensed in 2004. As the remaining
step-up relates to inventories accounted for on the LIFO method of accounting,
the company does not anticipate that additional amounts of step-up will be
expensed in the near term.

The adjusted fair value of the assets acquired and liabilities assumed in
connection with the Noveon International acquisition is as follows as of March
31, 2005:



Fair Value
of Net Assets
Acquired
(in millions of dollars) -------------

Receivables $ 188.5
Inventories 180.5
Other current assets 53.3

Total liabilities 1,424.4

Increase in net assets from acquisition $ 828.6
========


The company's operating results only include revenues and expenses of Noveon
International since June 3, 2004, the date of acquisition.

The following unaudited pro forma operating data is presented for the three
months ended March 31, 2004 as if the Noveon International acquisition had been
completed as of January 1, 2004. The pro forma data gives effect to actual
operating results prior to the acquisition. Adjustments to cost of sales for the
inventory step-up charge, fixed asset depreciation, intangible asset
amortization, the write-off of acquired IPR&D, interest expense and income taxes
related to the acquisition are reflected in the pro forma data. In addition, the
company assumed that the bridge loan obtained at the time of transaction closing
was not replaced with the permanent long-term financing, until the end of

the fourth month in 2004. As a result, there is no impact associated with the
permanent long-term financing, consisting of both debt and equity, in the pro
forma amounts presented below. These pro forma amounts do not purport to be
indicative of the results that would have actually been obtained if the
acquisition had occurred as of January 1, 2004 or that may be obtained in the
future.

On January 30, 2004, the company completed the acquisition of the coatings
hyperdispersants business of Avecia. This business is headquartered in Blackley,
United Kingdom and develops, manufactures and markets high-value additives that
are based on polymeric dispersion technology and used in coatings and inks.
These products enrich and strengthen color while reducing production costs and
solvent emissions, and are marketed under the brand names Solsperse(TM),
Solplus(TM) and Solthix(TM). Historical annual revenues of this business are
approximately $50.0 million. The 2004 historical results only include revenues
and expenses of hyperdispersants since the date of acquisition.

5. GOODWILL AND INTANGIBLE ASSETS

The major components of the company's identifiable intangible assets are
customer lists, technology, trademarks, patents, land-use rights and non-compete
agreements. Excluding the non-amortized trademarks, which are indefinite-lived
and will not be amortized, the intangible assets are amortized over the lives of
the respective agreements or other periods of value, which range between three
and forty years. We assess the indefinite-lived trademarks for impairment
separately from goodwill.

7. SEGMENT REPORTING

Beginning in the second quarter of 2004, the company reorganized as a result of
the Noveon International acquisition into two operating and reporting segments:
Lubricant Additives and Specialty Chemicals. The Lubricant Additives segment,
also referred to as Lubrizol Additives, represents 54% of the company's
consolidated revenues for the three months ended March 31, 2005 and is comprised
of the company's previous businesses in fluid technologies for transportation
(FTT), advanced fluid systems, emulsified products and the former industrial
additives product group of fluid technologies for industry (FTI). The Specialty
Chemicals segment, also referred to as the Noveon segment, represents 46% of the
company's consolidated revenues for the three months ended March 31, 2005 and is
comprised of the businesses of the acquired Noveon International and the former
performance chemicals group of FTI.

Lubricant Additives consists of three product lines: engine additives; specialty
driveline and industrial oil additives; and services and equipment. Engine
additives is comprised of additives for lubricating engine oils, such as for
gasoline, diesel, marine and stationary gas engines and additive components, and
additives for fuel products and refinery and oil field chemicals. In addition,
this product line sells additive components and viscosity improvers within its
lubricant and fuel additives product areas. Specialty driveline and industrial
oil additives is comprised of additives for driveline oils, such as automatic
transmission fluids, gear oils and tractor lubricants and industrial oil
additives, such as additives for hydraulic, grease and metalworking fluids, as
well as compressor lubricants. Services and equipment is comprised of fluid
metering devices, particulate emission trap devices, FluiPak(TM) sensor systems
and outsourcing strategies for supply chain and knowledge center management.
Lubricant Additives product lines are produced generally in company-owned shared
manufacturing facilities and sold largely to a common customer base.

The Specialty Chemicals segment consists of consumer specialties, specialty
materials and performance coatings product lines. The consumer specialties
product line is characterized by global production of acrylic thickeners,
specialty monomers, film formers, fixatives, emollients, silicones, surfactants,
botanicals, active pharmaceutical ingredients and intermediates, process
chemicals, benzoate preservatives, fragrances, defoamers, synthetic food dyes,
rubber and lubricant oxidants and rubber accelerators. The company markets
products in the consumer specialties product line to the following primary
end-use industries: personal care, pharmaceuticals, textiles, food and beverage,
automotive and aerospace. The consumer specialties products are sold to
customers worldwide and these customers include major manufacturers of
cosmetics, personal care products, water soluble polymers, household products,
soft drinks and food products and major manufacturers in the automotive and
aerospace industries. The specialty materials product line is characterized by

plastics. Specialty materials products are sold to a diverse customer base
comprised of major manufacturers in the construction, automotive,
telecommunications, electronics and recreation industries. The performance
coatings product line includes high-performance polymers for specialty paper,
printing and packaging, industrial and architectural specialty coatings and
textile applications. The company markets the performance coatings products
through the primary product categories of performance polymers and coatings and
textile performance chemicals. Performance coatings products serve major
companies in the specialty paper, printing and packaging, paint and coatings,
and textile industries.

The company primarily evaluates performance and allocates resources based on
segment operating income, defined as revenues less expenses identifiable to the
product lines included within each segment, as well as projected future returns.
Segment operating income will reconcile to consolidated income before tax by
deducting restructuring charges, net interest expense, corporate expenses and
corporate other income (expense) that are not directly attributable to the
operating segments.

The following table presents a summary of the results of the company's
reportable segments for the three months ended March 31, 2005 and 2004 based on
the current reporting structure. During the second quarter of 2004, the company
reclassified certain unallocated corporate expenses to segment operating income,
which previously had been excluded from the previously disclosed segment
contribution income. Amounts for the three months ended March 31, 2004 have been
restated to reflect the new reporting classifications of products between the
two operating segments and the new definition of segment operating income.

Expected employer contributions worldwide for pension benefits in 2005
approximate $30.5 million for the qualified plans, of which $5.9 million was
paid in the first quarter of 2005. The portion of the 2005 total expected
contributions attributable to the U.S. qualified pension plans is $17.7 million,
of which $1.3 million was paid in the first quarter of 2005. The non-qualified
pension plans are unfunded. As a result, the 2005 expected contributions to
these plans of $2.2 million represent an actuarial estimate of future assumed
payments based on historic retirement and payment patterns.

9. RESTRUCTURING CHARGES

In the three months ended March 31, 2005, the company recorded aggregate
restructuring charges of $6.1 million primarily related to the phase-out of
manufacturing facilities in both the Lubricant Additives and Specialty Chemicals
segments. The company made the decision to close these facilities to reduce
costs while simultaneously improving its service capabilities to customers. The
following table shows the reconciliation of the liability since December 31,
2004 by major restructuring activity:

==== ==== ===== ===== ====


In February 2005, management made the decision to close two Specialty Chemicals
coatings additives production facilities in the United States. The company
announced this decision in March 2005. The aggregate restructuring charge
recorded for these closures was $5.0 million, comprised of $4.4 million in asset
impairments, $0.4 million in exit costs and $0.2 million in severance costs. The
company estimates it will incur cumulative severance costs of approximately $2.1
million relating to these closures. An impairment charge for both plants was
recorded in the first quarter of 2005 to reflect the related assets at their
estimated fair values. The estimated fair value of the assets primarily was
determined from third-party appraisals. Production for these sites will be
transferred to other facilities in the United States. The facility in
Mountaintop, Pennsylvania is scheduled to close in the third quarter of 2005.
The facility in Linden, New Jersey is scheduled to close in the second quarter
of 2006. These closures will result in a workforce reduction of 62 employees by
the second quarter of 2006.

In December 2004, management made the decision to close the Lubricant Additives
manufacturing facility in Bromborough, United Kingdom. The company announced
this decision in January 2005. The company determined, as of December 31, 2004,
that an impairment of certain of the facility's long-lived assets had been
triggered by this decision in the fourth quarter of 2004. As a result, a $17.0
million impairment charge was recorded in December 2004 to reflect the related
assets at their estimated fair values. The estimated fair value of the assets
was determined using a discounted cash flow model. Production phase-out of this
site is planned to begin in the third quarter of 2005 and is expected to be
completed by late 2006. During this phase-out, United Kingdom production will be
transferred to facilities in France and the United States. Approximately 69
employees will be impacted by this closure. There were no significant changes to
the impairment calculation in the first quarter of 2005. The first quarter 2005
charge was comprised of $0.6 million in severance costs and $0.2 million in
other exit costs. The company currently anticipates that future pre-tax charges
and cash expenditures of approximately $13.5 million to $15.5 million will be
incurred in 2005 through 2006 to satisfy severance and retention obligations,
plant dismantling, site restoration and other site environmental evaluation
costs and lease-related costs.

In 2004, the company eliminated more than 100 positions, primarily affecting
technical and commercial employees located at the Wickliffe, Ohio headquarters.
Most of these workforce reductions were related to the restructuring following
the acquisition of Noveon International. These reductions were completed by
December 31, 2004.

The company assumed a restructuring liability of $7.2 million in 2004 relating
to the legacy operations of Noveon International. This liability was $6.1
million at December 31, 2004. The Specialty Chemicals segment also recorded an
additional restructuring charge of $0.3 million in 2005 relating to pension
costs associated with previously announced restructuring activities.

The charges for these cost reduction initiatives are reported as a separate line
item in the consolidated income statements, entitled "Restructuring charges" and
are included in the "Total cost and expenses" subtotal on the consolidated
income statements.

10. DEBT

On March 29, 2005, the company amended and restated its five-year unsecured bank
credit agreement to reduce the credit spread that is paid on the outstanding
$500.0 million term loans. Based on the company's current unsecured senior debt
ratings from Standard and Poor's and Moody's Investors Services, the credit
spread on the term loans was reduced by 50 basis points. No other terms or
conditions of the agreement were modified.

12. CONTINGENCIES

The company has numerous purchase commitments for materials, supplies and energy
in the ordinary course of business. The company has numerous sales commitments
for product supply contracts in the ordinary course of business.

General

There are pending or threatened claims, lawsuits and administrative proceedings
against the company or its subsidiaries, all arising from the ordinary course of
business with respect to commercial, product liability and environmental
matters, which seek remedies or damages. The company believes that any liability
that may finally be determined with respect to commercial and product liability
claims should not have a material adverse effect on the company's consolidated
financial position, results of operations or cash flows. From time to time, the
company is also involved in legal proceedings as a plaintiff involving contract,
patent protection, environmental and other matters. Gain contingencies, if any,
are recognized when they are realized.

Environmental

The company's environmental engineers and consultants review and monitor
environmental issues at operating facilities and, where appropriate, the company
initiates corrective and/or preventive environmental projects to ensure
environmental compliance and safe and lawful activities at its current
operations. The company also conducts compliance and management systems audits.

The company and its subsidiaries are generators of both hazardous and
non-hazardous wastes, the treatment, storage, transportation and disposal of
which are regulated by various laws and governmental regulations. These laws and
regulations generally impose liability for costs to investigate and remediate
contamination without regard to fault and, under certain circumstances,
liability may be joint and several resulting in one party being held responsible
for the entire obligation. Liability may also include damages to natural
resources. Although the company believes past operations were in substantial
compliance with the then-applicable regulations, either the company or the
predecessor of Noveon International, the Performance Materials Segment of
Goodrich Corporation (Goodrich), has been designated under a country's laws
and/or regulations as a potentially responsible party (PRP) in connection with
several sites including both third party sites and/or current operating
facilities.

The company participates in the remediation process for onsite and third-party
waste management sites at which the company has been identified as a PRP. This
process includes investigation, remedial action selection and implementation, as
well as discussions and negotiations with other parties, which primarily include
PRPs, past owners and operators and governmental agencies. The estimates of
environmental liabilities are based on the results of this process. Inherent
uncertainties exist in these estimates primarily due to unknown conditions,
changing governmental regulations and legal standards regarding liability,
remediation standards and evolving technologies for managing investigations and
remediations. The company revises its estimates accordingly as events in this
process occur and additional information is obtained.

The company's environmental reserves, measured on an undiscounted basis, totaled
$25.6 million at March 31, 2005 and $26.4 million at December 31, 2004. Of these
amounts, $3.9 million and $4.5 million were included in accrued expenses and
other current liabilities at March 31, 2005 and December 31, 2004, respectively.
The company's March 31, 2005 balance sheet includes liabilities, measured on an
undiscounted basis, of $14.4 million to cover future environmental expenditures
for Noveon International sites either payable by Noveon International or
indemnifiable by Goodrich. Accordingly, the current portion of the Noveon
International environmental obligations of $0.5 million is recorded in accrued
expenses and other current liabilities and $1.1 million of the recovery due from
Goodrich is recorded in receivables. Non-current Noveon International
liabilities include $13.9 million and other assets include $2.6 million
reflecting the recovery due from Goodrich.

Goodrich provided Noveon International with an indemnity for various
environmental liabilities. The company estimates Goodrich's share of such
currently identified liabilities under the indemnity, which extends through
February 2011, to be approximately $3.7 million. There are specific
environmental contingencies for company-owned sites for which third parties such
as past owners and/or operators are the named PRPs and also for which the
company is indemnified by Goodrich. Goodrich is currently indemnifying Noveon
International for several environmental remediation projects. Goodrich's share
of all of these liabilities may increase to the extent such third parties fail
to honor their obligations through February 2011.


-17-

THE LUBRIZOL CORPORATION
Notes to Consolidated Financial Statements
March 31, 2005

The company believes that its environmental accruals are adequate based on
currently available information. The company believes that it is reasonably
possible that $2.3 million in additional costs may be incurred at certain
locations beyond the amounts accrued as a result of new information, newly
discovered conditions, changes in remediation standards or technologies or a
change in the law. Additionally, as the indemnification from Goodrich extends
through February 2011, changes in assumptions regarding when costs will be
incurred may result in additional expenses to the company. Additional costs in
excess of $2.3 million cannot currently be estimated.

13. GUARANTOR AND NON-GUARANTOR SUBSIDIARY INFORMATION

The repayment of the unsecured senior notes, debentures and bank term loans is
unconditionally guaranteed on a joint and several basis by the company and its
direct and indirect, wholly owned, domestic subsidiaries. The following

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

This Management's Discussion and Analysis of Financial Condition and Results of
Operations should be read in conjunction with the unaudited consolidated
financial statements and the notes thereto appearing elsewhere in this quarterly
report on Form 10-Q. Historical results and percentage relationships set forth
in the consolidated financial statements, including trends that might appear,
should not be taken as indicative of future operations. The following discussion
contains forward-looking statements that involve risk and uncertainties. Our
actual results may differ materially from those discussed in such
forward-looking statements as a result of various factors, including those
described under the section "Cautionary Statements for Safe Harbor Purposes"
included elsewhere in this quarterly report on Form 10-Q.

OVERVIEW

We are an innovative specialty chemical company that produces and supplies
technologies that improve the quality and performance of our customers' products
in the global transportation, industrial and consumer markets. Our business is
founded on technological leadership. Innovation provides opportunities for us in
growth markets as well as advantages over our competitors. From a base of
approximately 2,400 patents, we use our product development and formulation
expertise to sustain our leading market positions and fuel our future growth. We
create additives, ingredients, resins and compounds that enhance the
performance, quality and value of our customers' products, while minimizing
their environmental impact. Our products are used in a broad range of
applications, and are sold into stable markets such as those for engine oils,
specialty driveline lubricants and metalworking fluids, as well as higher-growth
markets such as personal care and pharmaceutical products and performance
coatings and inks. Our specialty materials products are also used in a variety
of industries, including the construction, sporting goods, medical products and
automotive industries. We are an industry leader in the majority of our
businesses.

We are geographically diverse, with an extensive global manufacturing, supply
chain, technical and commercial infrastructure. We operate facilities in 27
countries, comprised of production facilities in 21 countries and laboratories
in nine countries, through the efforts of more than 7,700 employees. We sell our
products in more than 100 countries and believe that our customers value our
ability to provide customized, high-quality, cost-effective performance
formulations and solutions worldwide. We also believe that our customers value
our global supply chain capabilities.

On June 3, 2004, we completed the acquisition of Noveon International, Inc.
(Noveon International), a leading global producer and marketer of
technologically advanced specialty materials and chemicals used in the
industrial and consumer markets. With the acquisition of Noveon International,
we have accelerated our program to attain a substantial presence in the personal
care and coatings markets by adding a number of higher-growth, industry-leading
products under highly recognizable brand names, including Carbopol(R), to our
already strong portfolio of lubricant and fuel additives, and consumer products.
Additionally, Noveon International has a number of industry-leading and strong,
cash flow-generating specialty materials businesses, including TempRite(R)
chlorinated polyvinyl chloride (CPVC) and Estane(R) thermoplastic polyurethane
(TPU).

We acquired Noveon International for cash of $920.2 million (inclusive of
certain seller expenses of $32.9 million) plus transaction costs of $11.4
million and less cash acquired of $103.0 million. In addition, we assumed
$1,103.1 million of long-term indebtedness from Noveon International.


-24-

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS (CONTINUED)

We initially financed the acquisition and related costs with the proceeds of a
$2,450.0 million 364-day bridge credit facility. Shortly after the acquisition,
we repaid substantially all of the assumed long-term debt with proceeds of the
temporary bridge loan. In addition, we repaid the temporary bridge loan in full
in September 2004 when we secured our permanent financing that included the
issuance of senior notes, debentures, bank term loans and equity.

Our consolidated balance sheet as of March 31, 2005 reflects the acquisition of
Noveon International under the purchase method of accounting. We recorded the
various assets acquired and liabilities assumed, primarily working capital
accounts, of Noveon International at their estimated fair values determined as
of the acquisition date. The allocation of the purchase price has not yet been
finalized, but is substantially complete, as of March 31, 2005. While we do not
expect any material changes, the purchase price allocation remains subject to
revision through the end of the allocation period in the second quarter of 2005.
Actuarial valuations were completed for the projected pension and other
post-employment benefit obligations and were reflected in the purchase price
allocation. We also obtained appraisals of long-lived assets and identifiable
intangible assets, including an evaluation of in-process research and
development (IPR&D) projects. Although substantially complete, our evaluation of
these appraisals is not yet final. We are still evaluating the impact of
information obtained during the allocation period from the due diligence
procedures performed relating to certain businesses and assets considered for
divestiture. In connection with the acquisition of Noveon International, we have
targeted non-core businesses with total revenues of approximately $300.0 million
to $500.0 million for disposition. This plan was contemplated at the time of
acquisition and plan activities have been underway since the fourth quarter of
2004. We are also still in the process of finalizing our reconciliation of the
underlying fixed-asset records to the respective valuations. As a result of both
of these efforts, in the first quarter 2005, we reduced the amount allocated to
property, plant and equipment by $43.9 million. The goodwill associated with the
transaction increased accordingly. Depreciation expense for the three months
ended March 31, 2005 includes a related adjustment for $1.2 million representing
the cumulative impact of the change in the estimated fair values assigned to
property, plant and equipment.

The purchase price included the estimated fair value of IPR&D projects totaling
$34.0 million that, as of the acquisition date, had not yet reached
technological feasibility and had no alternative future use. As a result, we
expensed the full amount allocated to IPR&D in 2004. There have been no changes
to the valuation of IPR&D in 2005. The inventory step-up to fair value totaled
$24.2 million, of which $9.8 million was expensed in 2004. As the remaining
step-up relates to inventories accounted for on the LIFO method of accounting,
we do not anticipate that additional amounts of step-up will be expensed in the
near term.

In 2005, we have continued to integrate the Noveon International acquisition
ahead of schedule. We are projecting to realize savings in 2005 of approximately
$35.0 million. We currently expect to reach our target run rate of $40.0 million
in annual savings by the end of 2005, which is 18 months ahead of original
expectations.

In conjunction with the integration of Noveon International, we have also made
progress in our plan to divest non-core businesses. In the first quarter of
2005, we selected investment bankers to assist us with the process. We have
distributed offering memoranda for some of the businesses and we are planning to
distribute offering materials for the rest of the businesses in the second
quarter of 2005. We do not believe the businesses or assets we are evaluating
are considered held for sale pursuant to the provisions of Statement of
Financial Accounting Standards (SFAS) No. 144, "Accounting for the Impairment or
Disposal of Long-Lived Assets," as of March 31, 2005.


-25-

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS (CONTINUED)

In June 2004, we reorganized our business as a result of the Noveon
International acquisition into two operating and reporting segments: the
Lubricant Additives segment and the Specialty Chemicals segment. The Lubricant
Additives segment is comprised of our previous business in fluid technologies
for transportation (FTT), advanced fluid systems, emulsified products and the
former industrial additives product group of fluid technologies for industry
(FTI). The Specialty Chemicals segment is comprised of the businesses of the
acquired Noveon International and the former performance chemicals group of FTI.
Note 7 to the unaudited consolidated financial statements contains our segment
reporting disclosure including a further description of the nature of our
operations, the product lines within each of the reporting segments and related
financial disclosures for the reportable segments. See also "Segment Analysis"
for further financial disclosures by reporting segment, including segment
profitability.

RESULTS OF OPERATIONS

First quarter 2005 net income increased over the prior-year first quarter as
acquisitions, improved price and product mix and favorable currency more than
offset higher raw material costs and lower shipment volume. The acquisition of
Noveon International in June 2004 contributed $0.05 to earnings per share in the
quarter after considering incremental equity issuances and financing costs. The
$0.06 per share in restructuring charges primarily related to the phase-out of
manufacturing facilities located in Bromborough, United Kingdom; Linden, New
Jersey; and Mountaintop, Pennsylvania.

REVENUES

The changes in consolidated revenues are summarized as follows:



Three Months Excluding
Ended March 31, Acquisitions
--------------- -------------------
(in millions of dollars) 2005 2004 $ Change % Change $ Change % Change
------ ------ -------- -------- -------- --------

Net sales $970.1 $577.9 $392.2 68% $36.5 6%

------ ------ ------ -----
Total revenues $971.0 578.7 $392.3 68% $36.6 6%
====== ===== ====== =====


The 2004 acquisitions accounted for the majority of the increase in consolidated
revenues. Acquisitions in 2004 included Noveon International and the
hyperdispersants business purchased from Avecia. The 2004 acquisitions
contributed $355.7 million towards the increase in revenues in the first quarter
of 2005 compared with the same period in 2004, respectively.

Excluding acquisitions, revenues increased 6% in the first quarter of 2005 due
to a 10% improvement in price resulting from the cumulative affect of a series
of price increases over the past year and better product mix and a 2% favorable
currency impact, partially offset by a 6% decline in ongoing shipment volume.

Shipment volume patterns vary in different geographic zones. The following table
shows our shipment volume by geographic zone in the first quarter of 2005 as
well as the changes in shipment volume by geographic zone as compared with the
corresponding period in 2004.

Analysis" section below.

COSTS AND EXPENSES

The changes in consolidated costs and expenses are summarized as follows:



Three Months Excluding
Ended March 31, Acquisitions
--------------- -------------------
(in millions of dollars) 2005 2004 $ Change % Change $ Change % Change
------ ------ -------- -------- -------- --------

Cost of sales $717.1 $426.3 $290.8 68% $33.5 8%
Selling and administrative
expenses 92.9 51.9 41.0 79% 4.7 9%

------ ------ ------ -----
Total costs and expenses $873.2 $520.8 $352.4 68% $40.3 8%
====== ====== ====== =====


*Calculation not meaningful

Excluding acquisitions, the increase in cost of sales in the first quarter of
2005 compared with the same period in 2004 primarily was due to higher average
raw material cost partially offset by lower manufacturing expenses. Average raw
material cost increased 17% in the first quarter of 2005 compared with the same
period in 2004, primarily due to higher unit raw material cost along with
unfavorable currency effects. We expect higher raw material costs in the second
quarter of 2005 as compared to the first quarter of 2005.

Total manufacturing expenses, which are included in cost of sales, decreased 2%
in the first quarter of 2005 excluding acquisitions (increased 63% including
acquisitions), compared with the same period in 2004, primarily due to a 6%
decrease in shipment volume. In addition, there was a $2.0 million environmental
cost in the first quarter of 2004 that did not recur in 2005. On a per-unit-sold
basis, manufacturing costs increased 2% in the first quarter of 2005 compared to
2004, excluding acquisitions.


-27-

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS (CONTINUED)

Gross profit (net sales less cost of sales) increased $101.4 million, or 67%
($3.0 million, or 2%, excluding acquisitions), in the first quarter of 2005
compared with the same period in 2004. Excluding acquisitions, the increase
primarily was due to higher average selling price significantly offset by higher
average raw material cost and the effects of lower shipment volume. In addition,
increased sales from our equipment companies contributed to the higher gross
profit for the period. Our gross profit percentage (gross profit divided by net
sales) remained relatively flat at 26.1% (25.2% excluding acquisitions) in the
first quarter of 2005 compared to 26.2% in the first quarter of 2004. The gross
profit percentage decrease excluding acquisitions primarily was due to the
impact of increasing unit raw material costs compared to similar increases in
per unit sales prices.

The increase in selling and administrative expenses, excluding acquisitions,
primarily was due to higher compensation expense. We experienced a $6.5 million
increase in compensation related costs due to increases in variable compensation
and annual salaries, expenses associated with the consolidation of certain
administrative functions from Noveon International into corporate functions and
expenses related to our divestiture plans.

The decrease in research, testing and development expenses (technology
expenses), excluding acquisitions, in the first quarter of 2005 compared with
the same period in 2004 primarily was due to a decrease in testing at outside
laboratories of $2.3 million in the first quarter of 2005 compared to the same
period in 2004, along with a $0.6 million reduction in salary and benefit
expenses as a result of the 2004 reduction in workforce. We anticipate higher
testing expenses in the second quarter of 2005 as compared to the first quarter
of 2005 as we increase testing for the next North American diesel engine oil
upgrade.

The increased amortization expense in the first quarter of 2005 compared with
the same period in 2004 entirely was due to the Noveon International and
hyperdispersants acquisitions in 2004.

In the first quarter of 2005, we recorded aggregate restructuring charges of
$6.1 million, or $0.6 per share, primarily related to the phase out of three
manufacturing facilities in both the Lubricant Additives and Specialty Chemicals
segments. We made the decision to close these facilities to reduce costs while
simultaneously improving our service capabilities to customers. The components
of the 2005 restructuring charges are detailed as follows:



Three Months
Ended
(dollars in millions) March 31, 2005
--------------

Asset impairments - coatings facilities $4.4
Employee severance 1.1
Other plant exit costs 0.6
----
Total restructuring charges $6.1
====


In March 2005, we announced the decision to close two Specialty Chemicals
coatings additives manufacturing facilities in the United States. The aggregate
restructuring charge recorded for these closures was $5.0 million, comprised of
$4.4 million in asset impairments, $0.4 million in exit costs and $0.2 million
in severance costs. We estimate we will incur cumulative severance costs of
approximately $2.1 million relating to these closures. An impairment charge for
both plants was recorded in the first quarter of 2005 to reflect the related
assets at their estimated fair values. Production for these sites will be
transferred to other facilities in the United States. The facility in
Mountaintop, Pennsylvania is scheduled to close in the third quarter of 2005.
The facility in Linden, New Jersey is scheduled to close in the second quarter
of 2006. These closures will result in a workforce reduction of 62 employees by
the second quarter of 2006.


-28-

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS (CONTINUED)

In December 2004, we made the decision to close the Lubricant Additives
manufacturing facility in Bromborough, United Kingdom. We announced this
decision in January 2005. We determined, as of December 31, 2004, that an
impairment of certain of the facility's long-lived assets had been triggered by
this decision. As a result, a $17.0 million impairment charge was recorded in
December 2004 to reflect the related assets at their estimated fair values.
There were no significant changes to the impairment calculation in the first
quarter of 2005. We recorded an additional charge of $0.8 million in the first
quarter of 2005 comprised of $0.6 million in severance costs and $0.2 million in
other exit costs. Production phase-out of this site is planned to begin in the
third quarter of 2005 and is expected to be completed by late 2006. During this
phase-out, United Kingdom production will be transferred to facilities in France
and the United States. Approximately 69 employees will be impacted by this
closure. We currently anticipate that future pre-tax charges and cash
expenditures of approximately $13.5 million to $15.5 million will be incurred in
2005 through 2006 to satisfy severance and retention obligations, plant
dismantling, site restoration and other site environmental evaluation costs and
lease-related costs.

In addition to the restructuring charges recorded for the above facilities, we
also expect to invest approximately $8.8 million relating to the two Specialty
Chemicals plants and $20.0 million for Bromborough, respectively, over the next
two years for capacity upgrades at alternative manufacturing facilities that
will absorb production previously undertaken at these facilities. We expect
these facility closures and transfer of production to more efficient
manufacturing locations to generate annual pre-tax savings of approximately $3.9
million for Specialty Chemicals and $10.0 million for Bromborough by 2007.

In 2004, we eliminated more than 100 positions, primarily affecting technical
and commercial employees located at the Wickliffe, Ohio headquarters. Most of
these workforce reductions were related to the restructuring following the
acquisition of Noveon International. These reductions were completed by December
31, 2004 and resulted in $4.6 million in pre-tax savings in the first quarter of
2005. We estimate future annual pre-tax savings of approximately $18.3 million.

OTHER ITEMS AND NET INCOME

The changes in other items and net income are summarized as follows:



Three Months Excluding
Ended March 31, Acquisitions
--------------- -------------------
(in millions of dollars) 2005 2004 $ Change % Change $ Change % Change
------ ----- -------- -------- -------- --------

Other income - net $ 0.7 $ 4.3 $ (3.6) * $(3.7) *

Net income 48.5 37.5 11.0 29% (4.4) (12%)


*Calculation not meaningful

The decrease in other income in the first quarter of 2005, compared to the same
period in 2004, primarily was due to a decrease in currency translation gains of
$5.0 million. Other income for the first quarter of 2004 included a gain of $6.4
million, or $0.08 per share, on a currency forward contract to purchase pound
sterling related to the acquisition of the hyperdispersants business. We secured
the forward contract in December 2003 and completed the acquisition at the end
of January 2004. This gain partially was offset by other currency translation
losses.


-29-

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS (CONTINUED)

The increase in net interest expense for the first quarter of 2005, compared
with the same period in 2004, primarily was due to the Noveon International
acquisition-related financing costs of $14.3 million.

We had an effective tax rate of 34.4% for operating income before restructuring
charges in the first quarter of 2005 compared with 34.0% in the same period in
2004. The restructuring charges were taxed at an effective rate of 34.1%.

Primarily as a result of the above factors, our net income per share was $0.72
for both the first quarter of 2005 and the comparable period of 2004. The Noveon
International acquisition, including equity issuances and transaction financing,
was accretive to earnings per share by $0.05 per share in the first quarter of
2005. Restructuring charges recorded in the first quarter of 2005 reduced
earnings by $0.06 per share. The gain on the foreign currency forward contract
increased first quarter 2004 earnings by $0.08 per share.

SEGMENT ANALYSIS

We primarily evaluate performance and allocate resources based on segment
operating income, defined as revenues less expenses identifiable to the product
lines included within each segment, as well as projected future returns. Segment
operating income will reconcile to consolidated income before tax by deducting
restructuring charges, net interest expense, corporate expenses and corporate
other income that we do not attribute to either operating segment.

During 2004, we reclassified certain unallocated corporate expenses to segment
operating income, which previously had been excluded from our previously
disclosed segment contribution income. We have restated our segment results for
2004 to reflect the new reporting classifications of products between the two
operating and reporting segments and the new definition of segment operating
income.

The Lubricant Additives segment represents approximately 54% and 57% of our
consolidated revenues and segment operating income, respectively, for the first
quarter of 2005. The Specialty Chemicals segment represents approximately 46%
and 43% of our consolidated revenues and segment operating income, respectively,
for the first quarter of 2005.

The operating results by segment for the three months ended March 31, 2005 and
2004 are as follows:

LUBRICANT ADDITIVES SEGMENT

Revenues increased 7% in the first quarter of 2005 compared to the same period
in 2004, primarily due to a 10% improvement in the combination of price and
product mix and 2% favorable currency impact, partially offset by 6% unfavorable
volume. In addition, higher revenues from our equipment companies contributed 1%
towards the 7% favorable increase in revenues in the first quarter of 2005.

Shipment volume patterns vary in different geographic zones. The following table
shows our shipment volume by geographic zone in the first quarter of 2005 as
well as the changes in shipment volume by geographic zone as compared with the
corresponding period in 2004.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS (CONTINUED)

Volume declined 6% in total and 13% in North America in the first quarter of
2005 as compared to the first quarter 2004. However, excluding the lost business
of a major international customer that was first disclosed in 2002, volume
declined 1% in total and 3% in North America. The remaining decrease in North
America in the first quarter of 2005 primarily was due to the higher
concentration associated with the new passenger car technical standard of GF-4
versus GF-3. Volumes in the first quarter of 2005 were also affected by 2004
year-end pre-buying in front of announced price increases, slower demand for
passenger car motor oil products and the transitional impact of order patterns
as our customers convert from the passenger car motor oil technical standard
GF-3 to GF-4. Higher shipment volume in Europe primarily was due to increases in
our engine additives product line due to market share gains. The shipment volume
decrease in Asia-Pacific primarily was due to timing of order patterns, which
more than offset 5% higher shipment volumes in China. The decrease in Latin
America, our smallest zone, primarily was due to some lost business within our
engine additives product line and a shift in finished fluid blending volume from
Latin America to North America.

The Lubricant Additives segment implemented a price increase beginning in April
2005 for all products sourced from North America, Asia-Pacific and Latin
America. We also recently announced a price increase, which will become
effective in mid-May 2005 for products sourced from Europe. These price
increases were in response to continuing raw material cost increases since our
last price increase in the fourth quarter of 2004.

Segment gross profit includes material cost and all manufacturing expenses.
Segment gross profit increased 4% in the first quarter of 2005 compared with the
same period in 2004. This increase primarily was due to the cumulative impact of
the selling price increases and flat manufacturing costs per metric ton,
partially offset by lower shipment volume. As a result, average gross profit per
metric ton increased by 8%. In the first quarter of 2005, average material cost
increased 20% compared to the first quarter of 2004. In addition, higher gross
profit from our equipment companies contributed 1% of the 4% increase in segment
gross profit.

The gross profit percentage for the segment was 25.5% in the first quarter of
2005, compared with 26.2% in the prior year first quarter. The decrease
primarily was due to raw material costs rising proportionally faster than
selling prices.

Selling, technical, administrative and research (STAR) expenses were flat in the
first quarter of 2005 compared with the first quarter of 2004. Technical
expenses decreased $2.0 million primarily due to savings associated with the
June 2004 workforce reduction. Lower technical expenses were offset by higher
administrative expenses and marketing expenses.

Other income increased by $1.2 million in the first quarter of 2005 compared
with the same prior year period, partially due to a new commercial arrangement
for intellectual property.

Segment operating income (revenues less expenses attributable to the product
lines aggregated within each segment) increased 10% for the first quarter of
2005 compared with the same period in 2004 due to the factors discussed above.

SPECIALTY CHEMICALS SEGMENT

Revenues for the Specialty Chemicals segment increased 414% in the first quarter
of 2005 compared with the same period in the prior year primarily due to the
2004 acquisitions of Noveon International and the hyperdispersants business.
Excluding acquisitions, segment revenues increased 4% in the first quarter of
2005 compared with the same period in 2004 due to an 8% improvement in the
combination of price and product mix and a 1% favorable currency impact
partially offset by a 5% decrease in shipment volume. The higher-priced product
mix primarily occurred in our consumer specialties product line and to a lesser
extent in our performance coatings product line.

Shipment volume patterns vary in different geographic zones. The following table
shows our shipment volume by geographic zone in the first quarter of 2005 as
well as the changes in shipment volume by geographic zone as compared with the
corresponding period in 2004.

Total 100% 251% (5%)
===


Excluding acquisitions, the shipment volume decrease in North America for the
first quarter of 2005 occurred in both our performance coatings and consumer
specialties product lines. The decrease in these product lines was due to our
exiting activities for certain low margin business and some changes in order
patterns as first quarter 2004 shipments were higher than normal. The increase
in Europe primarily was due to new business gained in our consumer specialties
business. The decrease in Asia-Pacific / Middle East was due to lower shipment
volumes across all of our product lines resulting from lower demand and order
pattern, as we experienced higher than normal volumes in this region in the
first quarter of 2004.

Segment gross profit increased $96.8 million, or 425% (decreased $1.6 million,
or 7%, excluding acquisitions), in the first quarter of 2005 compared with the
same period in 2004. Excluding acquisitions, the decrease in segment gross
profit for the first quarter was due to higher raw material costs and
manufacturing expenses, partially offset by higher revenues due to an
improvement in the combination of price and product mix. Average raw material
cost increased 10% compared with 2004. Manufacturing expenses increased $3.4
million primarily due to higher spending and a transfer of expenses from STAR to
manufacturing in our consumer specialties product line.

The gross profit percentage for this segment was 26.8% in the first quarter of
2005 compared with 26.3% in the respective period in 2004. Excluding
acquisitions, the gross profit percentage was 23.4% in the first quarter of
2005. The decrease in gross profit percentage was due to higher raw material
costs and manufacturing expenses partially offset by an improvement in the
combination of price and product mix.

STAR expenses increased $45.3 million, or 265%, for the first quarter of 2005
(decreased $4.4 million, or 26%, excluding acquisitions) compared with the same
period in 2004. Excluding acquisitions, the decrease in STAR expenses primarily
was due to reduced spending as a result of the integration of general and
administrative functions, a reduction in the amount of corporate services
expenses that are allocated to the Specialty Chemicals segment and a transfer of
expenses from STAR to manufacturing in our consumer specialties product line.

Segment operating income increased $46.6 million in the first quarter of 2005
(increased $2.4 million, excluding acquisitions) compared with the same period
in 2004. Excluding acquisitions, the increase in segment operating profit for
the first quarter primarily was due to the decrease in STAR expenses, partially
offset by the decrease in segment gross profit.

PRO FORMA ANALYSIS

The following table presents major components of and information derived from
the pro forma consolidated statement of income and pro forma consolidated
statement of cash flows for the three months ended March 31, 2004. The major
components of the pro forma consolidated statement of income and pro forma
consolidated statement of cash flows reflect the effect of the acquisition of
Noveon International on June 3, 2004 as if the acquisition occurred as of
January 1, 2004. We believe that this data provides the financial statement
reader with information that is useful in understanding the impact of the
acquisition of Noveon International on our results of operations and cash flows.

The components of and information derived from the pro forma consolidated
statement of income and the pro forma consolidated statement of cash flows for
the three months ended March 31, 2004 are derived from our unaudited
consolidated financial statements for the three months ended March 31, 2004 and
the unaudited consolidated financial statements of Noveon International for the
three months ended March 31, 2004.

Our consolidated balance sheet as of March 31, 2005 reflects the acquisition of
Noveon International under the purchase method of accounting. We recorded
various assets acquired and liabilities assumed, primarily working capital
accounts, of Noveon International at their estimated fair values as of the
acquisition date that we determined based on the information currently
available. The allocation of the purchase price has not yet been finalized, but
is substantially complete, as of March 31, 2005. While we do not expect any
material changes, the purchase price allocation remains subject to revision
through the end of the allocation period in the second quarter of 2005, as
appraisals of the long-lived assets are still being finalized.

The pro forma data gives effect to actual operating results of Noveon
International prior to the acquisition. Adjustments to cost of sales for the
inventory step-up charge of $9.8 million, the write-off of acquired IPR&D of
$34.0 million, estimated intangible asset amortization, estimated fixed asset
depreciation, interest expense and income taxes related to the acquisition are
reflected in the pro forma data. The entire inventory step-up charge is
attributable to the Specialty Chemicals segment. In addition, we assumed that
the bridge loan obtained at the time of transaction closing was not replaced
with the permanent long-term financing, until the end of the fourth month in
2004. As a result, there is no impact associated with the permanent long-term
financing, consisting of both debt and equity, in the pro forma amounts
presented below. This pro forma data is consistent with the pro forma data that
is disclosed in Note 3 to the unaudited consolidated financial statements for
the three months ended March 31, 2004. These pro forma amounts do not purport to
be indicative of the results that would have actually been obtained if the
acquisition had occurred as of January 1, 2004 or that may be obtained in the
future.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS (CONTINUED)

OPERATING ACTIVITIES

The increase in cash provided by operating activities in the first quarter of
2005 compared with the prior year first quarter primarily was due to an increase
in earnings after adjusting for non-cash items. The increase in earnings
partially was offset by a working capital build-up in inventory, which used cash
of $26.7 million, primarily due to increased material costs as well as some
build-up of strategic inventory stocks for key finished goods and intermediates.
There was a decrease in accounts payable and accrued expenses since December 31,
2004 resulting in a use of cash of $9.6 million as compared to proceeds of $21.3
in the comparable prior-year period, primarily due to timing associated with the
payment of cyclical items such as compensation and benefit related accruals,
rebates, insurance and taxes.

We manage our levels of inventories and accounts receivable on the basis of
average days sales in inventory and average days sales in receivables. Our
target for accounts receivable is established taking into consideration the
weighted average of our various terms of trade for each segment. Our target for
days sales in inventory for each segment is established with the goal of
minimizing our investment in inventories while at the same time ensuring
adequate supply for our customers. We continue to expect incremental improvement
as compared to 2004 by the end of the year.

INVESTING ACTIVITIES

Our capital expenditures in the first quarter of 2005 were $29.7 million, as
compared with $19.9 million for the same period in 2004. In 2005, we estimate
annual capital expenditures will be approximately $162.0 million, including
$12.0 million in additional expenditures related to the phase-out of three
manufacturing facilities.

The net decrease in cash used to fund acquisitions in the first quarter of 2005
as compared to the prior year quarter relates to the acquisition of the
hyperdispersants business of Avecia.

FINANCING ACTIVITIES

The decrease in cash provided by financing activities of $35.2 million in the
first quarter of 2005 primarily was due to the short-term borrowings that
financed the hyperdispersants acquisition in the first quarter of 2004.

CAPITALIZATION AND CREDIT FACILITIES

At March 31, 2005, our total debt outstanding of $1,957.9 consisted of 54%
fixed-rate debt and 46% variable-rate debt, including $400.0 million of
fixed-rate debt that effectively has been swapped to variable-rate debt. Our
weighted-average borrowing rate as of March 31, 2005 was approximately 5%.

Our net debt to capitalization ratio at March 31, 2005 was 51%. Net debt is the
total of short-term and long-term debt, reduced by cash and short-term
investments excluding original issue discounts and 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 56% at March 31, 2005.

Our ratio of current assets to current liabilities increased from 2.4 at
December 31, 2004 to 2.7 at March 31, 2005, primarily due to working capital
increases associated with higher sales and timing. The increase in accounts
receivable of $34.5 million since December 31, 2004 primarily was driven by
higher sales in the first quarter of 2005 as compared to the fourth quarter of
2004. The increase in inventory of $18.7 million primarily was due to increased
material costs. The decrease in accounts payable, accrued expenses and other
current liabilities of $42.6 million since December 31, 2004 primarily was due
to disbursement timing associated with the payment of items such as compensation
and benefit related accruals, dividends, rebates, insurance and taxes.


-37-

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS (CONTINUED)

At March 31, 2005, we had a $500.0 million revolving credit facility that
matures in August 2009, which allows us to borrow at variable rates based upon
the U.S. prime rate or LIBOR plus a specified credit spread. As of March 31,
2005, we had no outstanding borrowings under this agreement.

On March 29, 2005, we amended and restated our five-year unsecured bank credit
agreement to reduce the credit spread paid on the outstanding $500.0 million
term loans. Based on our current unsecured senior debt ratings from Standard and
Poor's and Moody's Investors Services, the credit spread on the term loans was
reduced by 50 basis points. No other terms or conditions of the agreement were
modified.

CONTRACTUAL CASH OBLIGATIONS

Our contractual cash obligations as of December 31, 2004 are contained on page
21 of our 2004 Annual Report to shareholders. We do not believe there have been
any significant changes since December 31, 2004 in that information.

Our debt level will require us to dedicate a significant portion of our cash
flow to make interest and principal payments, thereby reducing the availability
of our cash flow for acquisitions or other purposes. Nevertheless, we believe
our future operating cash flows will be sufficient to cover our debt repayments,
capital expenditures, dividends and other obligations and that we have untapped
borrowing capacity that can provide us with additional financial resources. We
currently have a shelf registration statement filed with the Securities and
Exchange Commission (SEC) under which $359.8 million of debt securities,
preferred shares or common shares may be issued. In addition, as of March 31,
2005, we maintained cash and short-term investment balances of $339.8 million
and had $500.0 million available under our revolving credit facility.

NEW ACCOUNTING STANDARDS

In March 2005, the Financial Accounting Standards Board (FASB) issued
Interpretation (FIN) No. 47, "Accounting for Conditional Asset-Retirement
Obligations." This standard codifies SFAS No. 143, "Asset-Retirement
Obligations," and states that companies must recognize a liability for the fair
value of a legal obligation to perform asset-retirement obligations that are
conditional on a future event if the amount can be reasonably estimated.
Specifically, FIN No. 47 provides additional guidance on whether the fair value
is reasonably estimable. FIN No. 47 is effective for us starting January 1,
2006. We do not believe the adoption of this standard will have a material
impact on our financial position, results of operations or cash flows.

In December 2004, the FASB issued SFAS No. 123(R), "Share-Based Payment." This
standard will require compensation costs related to share-based payment
transactions to be recognized in the financial statements. With limited
exceptions, the amount of compensation cost will be measured based on the
grant-date fair value of the equity or liability instruments issued. In
addition, liability awards will be remeasured each reporting period.
Compensation cost will be recognized over the period that an employee provides
service in exchange for the award. This standard replaces SFAS No. 123 and
supersedes Accounting Principles Board (APB) Opinion No. 25, "Accounting for
Stock Issued to Employees," and applies to all awards granted, modified,
repurchased or cancelled after July 1, 2005. In April 2005, the SEC amended the
compliance date of SFAS No. 123(R) through an amendment of Regulation S-X. The
new effective date for us is January 1, 2006. We are currently evaluating the
provisions of this standard to determine the impact on our consolidated
financial statements. It is, however, expected to reduce consolidated net
income.


-38-

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS (CONTINUED)

In December 2004, the FASB issued SFAS No. 153, "Exchanges of Nonmonetary
Assets." This standard amended APB Opinion No. 29, "Accounting for Nonmonetary
Transactions," to eliminate the exception from fair value measurement for
nonmonetary exchanges of similar productive assets. This standard replaces this
exception with a general exception from fair value measurement for exchanges of
nonmonetary assets that do not have commercial substance. A nonmonetary exchange
has no commercial substance if the future cash flows of the entity are expected
to change significantly as a result of the exchange. This statement is effective
for all nonmonetary asset exchanges we complete starting January 1, 2006. We do
not believe the adoption of this standard will have a material impact on our
financial position, results of operations or cash flows.

In November 2004, the FASB issued SFAS No. 151, "Inventory Costs," to clarify
the accounting for abnormal amounts of idle facility expense, freight, handling
costs and wasted material. This standard requires that such items be recognized
as current-period charges. The standard also establishes the concept of "normal
capacity" and requires the allocation of fixed production overhead to inventory
based on the normal capacity of the production facilities. Any unallocated
overhead must be recognized as an expense in the period incurred. This standard
is effective for inventory costs incurred starting January 1, 2006. We do not
believe the adoption of this standard will have a material impact on our
financial position, results of operations or cash flows.

CAUTIONARY STATEMENTS 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. 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 any forward-looking statements, although we believe our expectations
reflected in those forward-looking statements are based upon reasonable
assumptions. For this purpose, any statements contained herein that are not
statements of historical fact should be deemed to be 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 cost, availability and quality of raw materials, including
petroleum-based products;

- - our ability to increase the prices of our products in a competitive
environment;

- - the effect of required principal and interest payments on our ability to
fund capital expenditures and acquisitions and to meet operating needs;

- - the overall global economic environment and the overall demand for our
products on a worldwide basis;

- - technology developments that affect longer-term trends for our products;

- - the extent to which we are successful in expanding our business in new and
existing markets;

- - our ability to identify, complete and integrate acquisitions for profitable
growth and operating efficiencies, especially our ability to integrate the
acquisition of Noveon International;

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

- - our ability to continue to reduce complexities and conversion costs and
modify our cost structure to maintain and enhance our competitiveness;


-39-

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS (CONTINUED)

- - our success in retaining and growing the business that we have with our
largest customers;

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

- - the effect of interest rate fluctuations on our interest expense;

- - 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 commercial
development programs;

- - significant changes in government regulations affecting environmental
compliance;

- - the ability to identify, understand and manage risks inherent in new
markets in which we choose to expand; and

- - our ability to maintain operating continuity for those businesses
identified as divestiture candidates.


-40-

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 and foreign
currency exchange rates. We believe the political and economic risks related to
our foreign operations are 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
our earnings and cash flow. Our objective in managing the exposure to changes in
foreign currency exchange rates is to reduce volatility on 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
hold derivatives for trading purposes.

A quantitative and qualitative discussion regarding our market risk is contained
on page 26 of our 2004 Annual Report to shareholders. There have been no
material changes in the market risks faced by us since December 31, 2004.

ITEM 4. CONTROLS AND PROCEDURES

We evaluated, under the supervision and with the participation of our chief
executive officer and chief financial officer, the effectiveness of our
disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e))
as of March 31, 2005. Based on that evaluation, our chief executive officer and
chief financial officer concluded that, as of March 31, 2005, our disclosure
controls and procedures were effective in timely alerting them to material
information relating to Lubrizol and our 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 first
quarter of 2005 that have materially affected, or are reasonably likely to
materially affect, our internal control over financial reporting.
