MathSoft Boosts Engineering Productivity and Collaboration With New Mathcad 2001i

Enhanced Version Brings the Performance, Functionality and Interactive Publishing Capabilities of Mathcad to the Windows XP Platform

CAMBRIDGE, Mass.--Nov. 13, 2001--MathSoft, the leading provider of interactive math,
science, engineering and educational software, content and Web services, today announced
Mathcad 2001i, an enhanced version of the industry-standard solution for applying math. New
and enhanced features improve how users create, communicate and collaborate on engineering
documents and designs. Mathcad 2001i also delivers full support for Windows XP, improvements
in usability, more data acquisition choices, enhanced security with the introduction of advanced
encrypted security to protect Mathcad documents, streamlined Web publishing, expanded
problem solving functions and a broader range of customization options.

For more than 10 years, MathSoft has contributed to technical innovation in engineering
throughout a broad range of markets and industries, including defense and aerospace,
telecommunications, electronics and electrical equipment, civil engineering and construction,
engineering services, government, and higher education. With over 1.5 million users, Mathcad is
the most widely used solution for applying mathematics and provides a technical calculation
environment that is optimized for both engineering efficiency and innovation.

"Mathcad makes it easy for us to model complex RF systems, predict their performance and
analyze the resultant data," said Albert Pergande, Senior RF Engineer for Lockheed Martin
Missiles and Fire Control Radar. "By combining capabilities for all of these tasks into one
application, Mathcad 2001i definitely saves time and helps me and my organization to be more
productive. The textbook-like interface, ease of making professional charts with the output and
the ability to make changes and see the results allows us to quickly, efficiently and clearly perform
tasks that otherwise would require a great deal of time and programming skill."

Through its patented technology and use of real math notation, Mathcad offers unmatched
simplicity for performing even the most complex calculations and designs. Mathcad's unique
graphical interface and self-documenting environment enable users to calculate, model, illustrate
and present their work in one integrated environment, making it the ideal tool for managing,
documenting and communicating technical work. Mathcad 2001i further enhances these core
capabilities by facilitating standards compliance within organizations through seamless integration
with other common applications used by engineers, including spreadsheets, Microsoft Office
applications, Visio, AutoCAD and MATLAB.

Mathcad 2001i also improves how users communicate engineering and math-related content with
colleagues and clients. Last year, Mathcad was the first technical calculation package to fully
support both the presentation and content forms of MathML (an XML standard for publishing
math on the Web approved by the World Wide Web Consortium), making it possible for users to
create and publish interactive math expressions on the Internet. Mathcad 2001i ships with a fully
integrated version of IBM techexplorer Professional Edition, an industry-leading MathML
renderer. Mathcad 2001i streamlines how users publish technical documents on the Web or
corporate intranet using unrivaled bi-directional translation of MathML along with new useful Web
templates. In addition, organizations licensing Mathcad 2001i and Mathcad Client, the recently
announced, low-cost distribution solution for Mathcad interactive content, can communicate work
efficiently and more cost-effectively.

"MathSoft knows that engineers and scientists are critical innovators in today's knowledge-based
economy, and we are committed to helping them by providing a tool that harnesses the latest
innovations in PC- and Web-based technologies," said Chris Randles, chairman and CEO of
MathSoft Engineering and Education, Inc. "The improvements in Mathcad 2001i announced today
enhance the productivity that engineering organizations enjoy with Mathcad by further merging the
traditional engineering design, collaboration and review processes."

MathSoft has enhanced Mathcad Professional with the following new features:

-- Enhanced security
Recognizing the increasing need for secure communication of designs or projects, MathSoft has
added advanced file-encryption functionality to keep document contents safe until they arrive in
the hands of the intended user. In addition, newly integrated document-protection technology lets
users lock all regions of Mathcad designs and calculations, making it possible to share results
without revealing proprietary processes. Mathcad 2001i also features new security settings to help
protect against embedded scripts that could potentially harm users' computer systems.

-- More data acquisition options
Mathcad 2001i adds support for data acquisition from Measurement Computing (formerly
ComputerBoards) analog DAQ boards and offers improved integration with National Instruments
devices.

-- Enhanced usability
MathSoft adds many valuable usability enhancements based on popular request, including new
2-D grid color options, 3-D axis labels, multi-region property settings and current-page printing.

-- Streamlined Web publishing
Mathcad 2001i builds on the bi-directional MathML support introduced in Mathcad 2001 by
adding new support for inline data, improved graphics and easier Web publishing with the
additional of Web templates. As a result, applying and communicating math on the Web becomes
seamless for Mathcad users.

-- Expanded problem solving
Mathcad 2001i features a new Radau ODE solver that offers faster, more accurate calculations.
Enhanced ODE solve blocks now support systems of differential equations and differential
algebraic equations, while nested solve blocks support more complex optimization problems.

-- Comprehensive automation
Mathcad 2001i offers enhanced automation interfaces for using Mathcad in embedded
applications. New interfaces to the Mathcad application, worksheets, windows and regions
provide a broader range of options for customizing Mathcad to perform routine or frequent tasks.

-- Windows XP support 
MathSoft continues to adapt its products for use with the most current Windows operating
systems. Mathcad 2001i is now specifically designed for Windows XP compatibility and also
supports Windows 98, Me, NT and 2000.

Mathcad 2001i Premium Edition

The comprehensive solution for power users, Mathcad 2001i Premium Edition provides a
complete, integrated technical-design environment for engineers to perform, communicate and
document their design process. The Premium Edition supports the initial mathematical design
specification, graphical and statistical analysis, and full 2D design and capture--while providing the
most complete solving and optimization power on the market. The Premium Edition also includes
all the feature improvements in Mathcad 2001i Professional, as well as SmartSketch 4, the new
version of Intergraph's easy-to-use design, drafting and diagramming application, Axum 7, the
soon-to-be-released version of the premier technical charting package for analyzing, exploring and
