Ethyl Shareholders Approve New Corporate Structure 
5/27/2004 
RICHMOND, Va. (May 27, 2004)  --Voting at their annual meeting, Ethyl Corporation's (NYSE: EY) shareholders have approved the company's move to a holding company structure. As previously announced the new holding company will be named NewMarket Corporation. Upon completion of the transaction, which is anticipated to take place on or before July 1, 2004, each share of the current Ethyl common stock will automatically be converted into one share of NewMarket common stock. NewMarket Corporation is expected to be listed on the New York Stock Exchange under the ticker symbol "NEU".

Following the establishment of the holding company structure and an internal restructuring of its subsidiaries, NewMarket will become the parent company of two operating companies each managing its own assets and liabilities. Those companies are Afton Chemical Corporation (formerly named Ethyl Petroleum Additives, Inc.) which focuses on petroleum additive products; and Ethyl Corporation, representing certain manufacturing operations and the tetraethyl lead (TEL) business that inspired the original Ethyl name.

Discussing the new structure, President and CEO Thomas E. Gottwald said: "We believe that the creation of NewMarket effectively mirrors the way we have reported operations for many years. At the same time, we believe that it will add important strengths as we continue to pursue the goals of our management team: new customer solutions, increased shareholder value, and enhanced employee opportunity."

Gottwald added "we believe that the creation of NewMarket brings clarity to our operating structure and will establish a foundation for our future evolution. We believe the holding company will facilitate acquisitions and joint ventures, diversification into new markets and improve financing options. Through our transition to NewMarket, our commitment to our customers to deliver the most innovative, productive value-added solutions emphatically remains unchanged."
