MOLECULAR ARTS CORPORATION RELEASES DESKTOP PUBLISHING SOFTWARE FOR
CHEMICAL RESEARCHERS

Anaheim, California, March 22, 1993 -- Molecular Arts Corporation (MAC),
announced today the commercial availability of a new version of its
popular Windows-based software, chemEXHIBIT for Windows, a desk-top
publishing tool for scientists in chemical research. This new release
(Version 2.0) of chemEXHIBIT offers sophisticated documentation,
illustration, and presentation capabilities designed specifically for
chemical research scientists. With chemEXHIBIT chemists can easily
display, manipulate, and render 3D molecular structures, create 2D
chemical diagrams, create publication-quality graphic illustrations,
import graphic images from 3rd-party applications, document the results of
their research, and produce professional-quality presentation materials.

Vice-President of Marketing for Molecular Arts Corporation, Laura Voyles
says of the new release, "chemEXHIBIT is an easy-to-use tool that provides
scientists tremendous capabilities for documenting and communicating their
chemical research activities. Chemists struggle daily with representing
their research (on 3D molecules) in 2D formats." She went on to say, "What
makes chemEXHIBIT so exciting is that it combines all the necessary 2D
documentation and presentation tools with 3D structure visualization and
2D chemical diagramming tools in an affordable desktop publishing package.
With chemEXHIBIT, scientists can document their work and present it to
their peers quickly and easily."

Graphical User Interface

By utilizing the popular Microsoft Windows graphical user interface,
chemEXHIBIT takes full advantage of this intuitive working environment,
making chemEXHIBIT easy to learn and use. Additionally, by integrating all
the necessary documentation and presentation tools under a single user
interface, chemEXHIBIT saves scientists time and money.

PRODUCT FEATURES

Included in chemEXHIBIT is a full suite of 2D diagram drawing tools,
CHEMGRAM, for creating 2D pictographs of chemical structures. CHEMGRAM
comes with 39 diagram drawing tools for drawing bonds, rings, orbitals,
and atom labels; "Snap To" drawing options; adjustable position, angle,
and bond length constraints; automatic superscripts and subscripts in
labels, and many other features making it an unparalleled package for
creating diagrams.

Users may also read in 3D structure models from third-party databases or
modeling programs. The VISAGE-3D rendering tools enable chemists to create
exactly the look they need to illustrate important research issues. The
VISAGE-3D toolset includes mixable rendering styles (wire frame,
ball-n-stick, space fill, and cylinder) with support for depth cueing,
perspective, shading, and stereo images. When used with the SELECT-3D
substructure selection tools, chemists can rapidly modify their visuals to
suit their documentation needs.

Additionally, the TAGIT-3D tools allow the user to identify and tag
important structural and chemical attributes of 3D models. Labels are
attached to 3D structures so that they travel together in 3D space if the
user decides to reorient the 3D structure. In this manner, important
features of complex structures will always be readily apparent to
observers.

Included in chemEXHIBIT are a full complement of page layout tools
including: optional on-screen page and margin outlines, a full-featured
text processor, formula and symbol libraries, a full compliment of graphic
drawing tools, and the ZOOMIN magnifying glass tool for highlighting key
aspects of 3D structures.

Users also have access to quality hardcopy output provided via support for
Hewlett Packard LaserJet printers, color printers, PostScript devices, HP
plotters - virtually all Windows-compatible output devices. Chemists can
create everything from slides and transparencies to oversized posters, lab
notebook annotations, and paper-based documentation.

AVAILABILITY

The commercial release of chemEXHIBIT (v2.0) is concurrent with this
announcement. A single-user industrial license is available for $595. This
release will operate on IBM PC's and PC-compatibles that support Microsoft
Windows 3.x. Included is a 90 day money-back guarantee and FREE technical
support for the first 3 months of ownership. Extended Support Plans are
available.
