Aceto Corporation and Nufarm Form Joint Venture and Acquire EPA Label for Butoxone.

Business Editors

LAKE SUCCESS, N.Y.--(BUSINESS WIRE)--Nov. 25, 2003

Aceto Corporation (Nasdaq:ACET), a global distributor of pharmaceutical and specialty chemicals, today announced that its subsidiary, Aceto Agricultural Chemicals Company, formed a joint venture with Nufarm Americas Inc., a subsidiary of Australia-based Nufarm Limited (ASX:NUF). The joint venture is named S.R.F.A., LLC. The parties have acquired, from Makhteshim-Agan of North America, Inc., EPA labels for Butoxone(R), an herbicide used on peanuts, soybeans and alfalfa. The terms of the acquisition, which encompasses all Butoxone labels, including the formulated labels, were not disclosed.

Aceto previously marketed this herbicide under a different label (2,4DB). Going forward, Aceto and Nufarm intend to market the herbicide in the U.S. solely under the Butoxone label, which has greater market penetration than 2,4DB. Nufarm will continue to formulate the product.

This joint venture reflects Aceto's strategy for expanding its agrochemical business, which is to partner with large agrochemical manufacturers and distributors to capitalize on the rapid consolidation of the industry. Due to the consolidation, a limited number of significant manufacturers remain, and the Company believes there is an impending disintermediation of the traditional supply channels for crop protection products, leaving the large distributors with the only option to find alternative sources, which Aceto will supply from Asian producers.
