Ethyl Reports Recent Developments in Canada on MMT® 
Richmond, VA (March 8, 2004) – Ethyl Corporation (NYSE-EY) - As we have previously announced, the Government of Canada recently released its “Proposed Framework for an Independent Third Party Review of New Information on the Effects of MMT® on Vehicle Emissions.”  In their proposal, the Canadian Government provided no timetable for the commencement or completion of the review.  Ethyl welcomes the independent third party review of MMT®, which we believe, when properly designed, conducted and interpreted, will reaffirm that MMT® is compatible with modern emission control devices. 

Ethyl Corporation has been informed by our two largest customers in Canada of their intention to suspend the use of the gasoline additive MMT® pending the results of the Government of Canada-sponsored independent third party review.  While this suspension will have a negative impact on our Canadian business, Ethyl’s management believes that the suspension is not likely to have a material adverse effect upon the overall financial performance of the Company.  MMT® is one of the most extensively tested fuel additives in history.  While we are disappointed with the decision of our customers, we believe that MMT® is an environmentally beneficial product that has proven its effectiveness in real-world use.

For more information regarding our MMT® business, please see our Annual Report on Form 10-K for the year ended December 31, 2003 that was recently filed with the Securities and Exchange Commission.
