CLEVELAND, Ohio, April 16, 2004 - The Lubrizol Corporation (NYSE: LZ) announced
today that it has signed a definitive agreement to purchase Noveon
International, Inc. in a transaction valued at $1.84 billion. The acquisition,
which has been approved by the boards of both companies, is subject to
regulatory approval and is expected to close within three months.

The addition of Noveon, a privately held Cleveland-based specialty chemical
company with $1.2 billion in revenues for the last 12 months, will create a
combined company with approximately $3.2 billion in annualized revenues. It will
complement Lubrizol's existing businesses in fluid technologies and, in
particular, it will expand the company's application base within the personal
care and specialty coatings markets. Noveon's businesses include several
high-growth, industry-leading product franchises marketed under well-recognized
brand names. These global brands include Carbopol(R) acrylic thickeners for
personal care, TempRite(R) chlorinated polyvinyl chloride resins and compounds,
Estane(R) thermoplastic polyurethane and Hycar(R) reactive liquid polymers for
engineering adhesives and water-borne acrylic emulsions for performance
coatings.

The transaction value includes a cash payment of approximately $920 million for
equity and the assumption of net debt, which was approximately $920 million as
of December 31, 2003. To fund the transaction, Lubrizol has secured a bridge
financing facility from Citicorp North America, Inc., which it intends to
refinance after the transaction closes.

Excluding transaction costs, Lubrizol expects the acquisition to be immediately
accretive to cash flow and accretive to earnings per share within 12 months of
the closing date.

"The acquisition of Noveon will allow us to carry out our vision of
enhancing our overall corporate growth rate," said W. G. Bares, chairman
and chief executive officer of Lubrizol.


                                    -more-

"Since 2000, we have made eight smaller acquisitions, with cumulative annualized
revenues of $200 million. These acquisitions successfully expanded our product
platform beyond our traditional business of fluid technologies for
transportation (FTT) into fluid technologies for industry (FTI). About a year
ago, our board and senior management concluded that, given the significant
progress to date in FTI coupled with the rapidly evolving global markets, the
time was right to intensify the pursuit of a larger acquisition that would be a
strong fit with FTI. The objective was not only to accelerate our progress
toward our financial and operational goals, but also to provide increasing value
to our employees, customers and shareholders. Noveon fits that strategy well by
broadening our product lines in personal care and coatings, complementing our
geographic reach, opening new market channels and enhancing our industry-leading
R&D capabilities."

 "Noveon is a well-run company," said Lubrizol's president, James L. Hambrick,
who will succeed Bares as CEO at the company's April 26 annual meeting of
shareholders. "It holds leading positions in a number of high-growth markets and
will give us the added breadth we need to leverage our technology into new
markets and applications. Our business will be better balanced following the
acquisition. Approximately one-half of our company will consist of Lubrizol's
traditional business, which concentrates on lubricant additives for the
transportation market and is a strong, stable and cash-generating business. The
other half will concentrate on the higher-growth areas of industrial and
consumer-related products. Once the transaction is completed, we will move
rapidly to integrate the acquisition and achieve synergies resulting from the
combination of the two organizations."

"The strengths of Noveon and Lubrizol complement each other well," said Steve
Demetriou, Noveon's president and chief executive officer. "This agreement will
be value-added for both companies and our respective customer bases, and will
enable the combined organization to build upon the successful foundation we have
established at Noveon. Since our inception three years ago, Noveon has
transformed itself into a leading specialty chemical company, revitalized its
businesses and reinvigorated its new product pipeline. The value we have created
at Noveon is reflected by our recent accomplishments which have included eight
consecutive quarters of year-over-year sales growth, relentless pursuit of
productivity initiatives, successful bolt-on acquisitions and global expansion."

Following the closing of the transaction, Noveon will become a wholly-owned
subsidiary of Lubrizol. The new Noveon subsidiary will include FTI and will have
annualized sales of approximately $1.6 billion.

Lubrizol expects the acquisition to result in a total of $40 million in cost
synergies. "These synergies are anticipated to come from savings in raw
materials, rationalization of manufacturing operations and other consolidation
opportunities," said Hambrick. "We plan to capture these synergies over the next
36 months."

Other synergies will include a stronger geographic platform for the combined
organization. For example, Lubrizol's coatings presence is stronger in Europe,
while Noveon's coatings business is stronger in North America. Both companies
also have expanding positions in China and Southeast Asia. Additionally, the
acquisition is expected to enhance both companies' R&D and product introduction
capabilities.

Citigroup Global Markets Inc. acted as exclusive financial advisor to
Lubrizol on this transaction.  Thompson Hine LLP acted as legal counsel
to Lubrizol.

EARNINGS UPDATE

Lubrizol also announced that it now expects to report first-quarter earnings in
the range of $.70 to $.72 per share, up from its previous guidance of $.53 to
$.58 per share. Earnings for the quarter include a currency forward contract
gain of approximately $.08 per share related to the acquisition of the Additives
business of Avecia, which was completed on January 30, 2004. Stronger volume and
product mix in lubricant additives - along with acquisitions, organic growth in
FTI and increased economic activity - have favorably impacted the Company's
performance in the first quarter. Lubrizol will release its first-quarter
earnings results on April 23.
