EXHIBIT 99.1 NEWS RELEASE for May 5, 2004 at 10:00 AM EDT - ----------------------------------------------------------------------------- Contact: Jack Davis (investor relations) 501-376-0044 Len Hall (media) 949-474-4300 len@allencaron.com Allen & Caron Inc KYZEN CORPORATION BOARD OF DIRECTORS ANNOUNCES DECISION NOT TO EXTEND WARRANTS; COMPANY TO DELIST FROM BOSTON STOCK EXCHANGE NASHVILLE, TN (May 5, 2004) . . . . Kyzen Corporation (OTCBB: KYZN.OB), a specialty chemical company that is a leading provider of products and processes for precision cleaning applications in high-technology manufacturing environments, today announced that its Board of Directors has decided not to further extend the Company's warrants (OTCBB: KYZNW.OB) beyond their August 4, 2004 termination date. Kyle J. Doyel, Kyzen's President and CEO, said, "Over the last four years the Board of Directors has twice extended the expiration date of Kyzen's warrants from the original August 4, 2000 expiration date. Increasing costs to comply with SEC requirements, as well as the related administrative costs, now make this a less attractive method to potentially raise capital. Therefore, the Board has made the decision to allow the warrants to expire on August 4, 2004." The Company also announced that its Board of Directors authorized the Company to delist its securities from the Boston Stock Exchange and trade exclusively on the OTC Bulletin Board. The Company expects to file a delisting application in the next few weeks and to delist from the Boston Stock Exchange upon receiving approval from the SEC. Doyel commented, "Since we became a public company in 1995, we have maintained our listing on the Boston Stock Exchange. In February 2000, the Company moved from the Nasdaq Small Cap Market to the OTC Bulletin Board service. At that time, we maintained our Boston Stock Exchange listing to enhance the liquidity of Kyzen's stock. Since we have been a public company, a total of approximately 300 shares of Kyzen Common Stock have been traded on the Boston Stock Exchange. Recognizing that the Boston Stock Exchange listing has not provided the additional liquidity we expected, we see no need to incur the additional expense of the Boston Stock Exchange listing." In an effort to increase shareholder value, the Board of Directors will continue to explore the best alternatives to control costs, particularly in light of the new reporting requirements mandated by the Sarbanes-Oxley Act of 2002 and, in particular, the new internal control reporting that must be enhanced in response to Section 404 of the Sarbanes-Oxley Act.
