DNA PLANT TECHNOLOGY UNVEILS SECOND GENERATION GENETICALLY-MODIFIED TOMATO.

OAKLAND, Calif.--(BUSINESS WIRE)--May 19, 1995--At its Annual Meeting of Shareholders yesterday in Oakland, California, DNA Plant Technology Corporation (NASDAQ: DNAP) unveiled the Company's second generation version of its genetically-modified tomato. In addition to the Company's patented Transwitch(R) technology, this latest version utilizes DNAP's own proprietary selectable marker gene and promoter technology.

In a presentation which included providing product samples for tasting by the meeting's attendees, Robert Serenbetz, Chairman and CEO of DNA Plant Technology, indicated that the newest version of the tomato is essentially identical to the Company's current version, which is in test market. He stated, "The superior taste, color and longevity of our tomato remains the same. The only difference is that it replaces the marker and promoter technology which is currently the subject of a dispute with Monsanto Corporation (NYSE: MTC)." Mr. Serenbetz indicated that the Company expects to begin production of the second generation genetically-modified tomato in September for initial launch into retail stores in December.

DNAP also announced that it is engaged in discussions with several parties relating to securing additional capital and is hopeful that it will be able to successfully conclude negotiations in the near future in order to obtain sufficient funds for its operating needs. As previously announced, DNAP recently concluded a private placement of 750,000 shares of its common stock and received approximately $1.4 million in net proceeds.
