                 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.
