 Tripos Reaches Agreement with Aldrich Chemical To Provide Catalog Database in
 UNITY/UNISON Format
 	St. Louis, MO January 2, 1996 Today Tripos, Inc. (NASDAQ: TRPS) and
 Aldrich Chemcial Co. (Milawaukee, Wisconsin) announced an agreement to provide
 the Aldrich chemical database in UNITY/UNISON format. UNITY/UNISON is Tripos'
 client-server chemical information management system used by pharmaceutical and
 chemical companies worldwide.
 	The new database will include information from the Aldrich, Sigma,
 Fluka, Supeloc, and Rare Chemicals catalogs. The Aldrich collection is the most
 extensive dataset of available chemicals with over a hundred thousand compounds.
 	Tripos will use its Concord technology to convert the 2D chemical
 structural data into 3D structures. The 3D structures may be searched using the
 UNITY system to find commercially available compounds matching user defined
 pharmacophores or a set of structural characteristics. These searches will play
 a key role in the discovery of new chemical and pharmaceutical products.
 	"The Aldrich chemical database is a recognized standard in the industry.
 Access to this dataset through UNITY/UNISON will allow chemists to combine
 chemical availability with structural and biological parameters in their route
 to new chemical discovery and applications," said Sheila Ash, Marketing
 Manager
 for Chemical Information at Tripos.
 	"The availability of the Aldrich collection of chemicals in UNITY/UNISON
 format will be important to the implementation of new combinatorial chemistry
 strategies by helping to target commercially available chemical building blocks.
 These components are critical to the development of potentially new
 products,"
 stated Dr. Mark Schwartz, Vice President of Accelerated Discovery Services (ADS)
 at Tripos.
 	Tripos plans to make the Aldrich chemical database available in the new
 format during the Spring of 1996.
 	Aldrich Chemical Co., based in Milwaukee, Wisconsin, is one of the
 world's largest sources of chemical and biochemical products for research use.
 	Tripos, Inc., founded in 1979, is the recognized leading supplier of
 scientific software and services to facilitate the discovery of new therapeutic
 and bioactive compounds in pharmaceutical, biotechnology, chemical and
 agrochemical industries.
