PANACEA AWARDED PATENT FOR SOFTWARE DISPLAY LIST TECHNOLOGY

LONDONDERRY, NH -- October 14, 1992 -- Panacea Inc. today announced that it
has been awarded U.S. patent number 5,101,444 for its display list
technology. Company officials stated that their newly developed technology
plays a crucial role in the soon to be released TurboDLD display list
software for AutoCAD, which provides speed improvements up to 4X faster
than the company's existing software display list processors. They also
noted that the patent is extendable to virtually any 2D, 3D, or
n-dimensional application which requires quick access to any subset of its
information.

Display list technology provides for graphical acceleration of CAD software
on computer displays by caching-graphical drawing information, much like
disk caches quickly retrieve frequently accessed computer data from a hard
drive. Thus individual graphical objects can be quickly located, even in
large drawing databases, and displayed on a monitor or other output
device.

Unlike existing display list drivers which perform a time-consuming
vector-by-vector comparison of an entire display list to determine which
objects will be shown on a monitor, Panacea's technology provides a means
to compare only the immediate area of interest, allowing the other
portions of the drawing database which are not part of the region of
interest to be completely ignored. This significantly reduces the time
required to produce an AutoCAD display onscreen. As an example, Panacea's
TurboDLDClassic and TurboDLDDeluxe display list drivers for AutoCAD
provide speed improvements by up to 25X in ZOOM, PAN, and REDRAW, which
are generally among the most time-consuming operations within AutoCAD.

According to Panacea founder Jake Richter, "We are very excited about this
patent, both from the standpoint of being able to Provide CAD users with
significantly improved display list performance as well as protect our
technology from 'migrating' into the wrong hands." Mr. Richter further
stressed that while existing software copyright laws covering all
commercially marketed products protect the unique "look and feel" of an
application, only patent protection, granted on a case-by-case basis,
sufficiently protects a unique software technology underlying a software
Product.
