Anaheim, California, August 17, 1992 -- Molecular Arts Corporation (MAC),
has announced today a new release of its popular Windows-based software,
chemEXHIBIT, a desk-top tool for scientists in chemical research. Version
1.1 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 product, "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 it 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 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. There is no longer
a need to purchase or wrestle with multiple, often incompatible, software
packages.

Unique Tools This release of chemEXHIBIT also marks the introduction of
several features that are uniquely designed for research documentation and
presentation tasks:

Tools                        Purpose
=========================    ====================================
CHEMGRAM:                    Advanced 2D Chemical Diagram Drawing
                             tools
ZOOMIN:                      3D molecular structure magnification
                             and highlighting tool. Chemists can
                             use ZOOMIN to direct their
                             audience's attention to specific
                             aspects of complex structures.
SELECT-3D:                   Expert 3D molecular substructure
                             identifier and selector
TAGIT-3D:                    Structural attributes identification
                             and 3D labeling (tagging) tool
VISAGE-3D:                   3D structure rending tools
Graphic drawing tools:       Illustrate research activities
Math and Symbol libraries:   Create complex math and chemical
                             formulas
Complete test editor:        Full-featured editor can be used to
                             create captions and text
Page Layout tools:           Design clean, professional documents

Seamlessly integrated together in chemEXHIBIT, these tools provide chemists
an unparalleled set of capabilities for creating professional-quality
documentation and presentation materials.

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 editor, 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 release of chemEXHIBIT (v1.1) is concurrent with this announcement. A
single-user industrial license is available for $595. Discounts are
available for academic and non-profit institutes. This release of
chemEXHIBIT will operate on IBM PC's and PC-compatibles that support the
Microsoft Windows 3.x graphical user interface. In the United States,
chemEXHIBIT is available directly from Molecular Arts Corporation. Prices
outside North America are slightly higher.
