 1992 BARK COLLECTION SEASON BEGINS;
 HAUSER PLANS TO EXCEED LAST YEAR'S COLLECTION OF 1,600,000 POUNDS
 COTTAGE GROVE, Ore./BOULDER, Colo., April 28 /PRNewswire/ -- Hauser Northwest Inc. and its parent company, Hauser Chemical Research Inc. (NASDAQ: HAUS), the only commercial producer of bulk taxol, announced today that the yew bark collection season has begun in the Pacific Northwest. Hauser Northwest plans to exceed last year's collection of 1,600,000 pounds of Pacific yew bark from public and private land. Hauser has imposed tough new standards on yew bark harvesters for the 1992 bark collection program. The new standards are designed to improve efficiency and tracking of the harvest process and are based upon knowledge gained from last year's harvest.
 "April begins our third harvest season as the authorized collector of yew bark for taxol used in clinical trials," said Mike Trumbull, general manager of Hauser Northwest. Hauser employes its proprietary extraction process to produce taxol for Bristol-Myers Squibb and the National Cancer Institute. "We are pleased with last year's accomplishments. We exceeded our harvest goals by salvaging bark from trees in clear cuts and established an environmentally sound program employing over 500 people. We are excited to begin the new season and to increase the availability of this important new drug."
 Hauser Northwest has made significant improvements since last year in procedures, coordination, monitoring and data gathering. "As always, bark harvesters authorized by Hauser Northwest will hold valid permits from public agencies or private land owners. This year, we are using an improved set of trip tickets developed in cooperation with the Forest Service, BLM, private landowners and law enforcement personnel from a variety of agencies," said Trumbull. Trip tickets can be obtained only from authorized yew bark collectors, and every load of bark will be tagged with a highly visible, color-coded trip ticket.
 Although the current source of taxol is Pacific yew bark, Hauser has completed a pilot process for production of taxol from the clippings of ornamental or nursery grown yew trees. Dependence on yew bark collected in the wild is expected to decrease as these alternative sources become available over the next 2-4 years. The company is also working with other researchers on methods of producing taxol in the laboratory.
 Hauser Chemical Research (the parent company of Hauser Northwest) is a chemical processor, specializing in the extraction and purification of high value natural products using its proprietary technologies. Additionally, through Hauser Laboratories, the company provides interdisciplinary laboratory testing services, chemical engineering services and contract research and development. The company is based in Boulder.
