INTERLEAF ANNOUNCES CYBERLEAF FOR INTERNET PUBLISHING

Easy-to-use desktop application accelerates production of multimedia
collections for World Wide Web

Waltham, MA - November 14, 1994 - Interleaf, Inc. (NASDAQ: LEAF) today
announced Cyberleaf, a new easy-to-use software package for publishing
information on the Internet's World Wide Web. Cyberleaf includes
everything a user needs to build and maintain professional-looking
collections or "webs" of information, made up of text, graphics and
multimedia files, which can be distributed on the Internet and viewed with
Mosaic-like browsers.

Ed Koepfler, Interleaf's President and CEO, said "Cyberleaf addresses the
needs of organizations large and small that want to reach the more than 30
million people currently accessing the Internet. In the new age of
information sharing, Interleaf will play a key role in empowering this
potentially huge market to communicate with a global audience faster than
ever."

Cyberleaf - Internet publishing made simple

Cyberleaf simplifies the process of publishing information on the Internet,
making it fast and easy to turn the output of any major word processing
application into information ready to be accessed over the Internet. With
Cyberleaf, authors and designers can use familiar applications, such as
Microsoft Word or WordPerfect, to publish on the Internet, rather than
having to adopt specialized text editors.

While the Mosaic browser, with its easy-to-use graphical interface, has
gained popularity for viewing documents on the Internet's World Wide Web,
until now the procedure for publishing documents on the Internet was
difficult and time-intensive, and required extensive technical knowledge.

Cyberleaf removes the technical barriers, making it easy for users at any
skill level to publish on the Internet. Its point-and-click interface
intuitively guides users through the conversion, hyperlinking and web
construction process. During this process, Cyberleaf takes documents
created with all major word processing and graphics applications and
converts them simultaneously to HyperText Markup Language (HTML) and
Graphics Interchange Format (GIF), the file formats that Mosaic displays
and which are considered Internet standards.

Cyberleaf also links documents together, so that users who access the
information on the World Wide Web can simply click on a keyword to move
spatially through piles of documents. This process, known as hyperlinking,
previously required time-intensive preparation and technical knowledge of
HTML. Cyberleaf allows users to quickly link many documents together to
form a cohesive web of information, without requiring that the user learn
HTML.

Robert Maher, Interleaf's Vice President of Document Publishing, said
"Cyberleaf will open the floodgates to the Internet because it makes it
fast and easy for any organization, including government, universities,
non-profit organizations, small and large businesses, as well as
individuals to publish information on the Internet."

Jay Weber, Director of Research and Development at Enterprise Integration
Technologies Corp. (EIT), a California-based R&D and consulting firm for
electronic commerce on the Internet, said "Cyberleaf is easy to use and
will significantly reduce the time required to publish documents on the
Internet. There is no other product like it. We're going to recommend it
highly to our customers."

Cyberleaf's major features include:

* Push-button graphical user interface. A workflow-oriented interface,
  ideal for users at any skill level, guides users through the
  conversion, hyperlinking and Internet web  construction process.
* Multiple format conversion. Cyberleaf converts Microsoft Word,
  WordPerfect, Interleaf, FrameMaker and ASCII formats.
* Simultaneous text and graphics conversion to HTML and GIF. Text and
  graphics are converted simultaneously to HTML and GIF, ensuring
  maximum productivity for the user.
* Easy-to-use hyperlinking. Hyperlinks contained in the original
  documents are preserved and converted directly to HTML. In addition,
  users can insert hyperlinks within and between documents, as well as
  link to any external file type, including audio and video.
* Style matching. During the conversion process, Cyberleaf analyzes
  the styles contained in the original documents and automatically
  matches those styles to equivalent HTML styles.
* Home page templates. A home page is the initial screen a user sees
  when accessing an Internet host on the World Wide Web. It provides a
  hyperlinked table of contents to the information an organization is
  making available on the Internet. Cyberleaf includes
  professionally-designed home page templates with sample graphics and
  layouts for constructing effective home pages for many information
  distribution applications.
* Document outlines. To facilitate browsing with Mosaic, long
  documents may be outlined based on selected style names such as
  chapter or section. Outline elements are automatically hyperlinked
  with their corresponding sections so that readers can quickly find
  the information they're looking for.
* Web document management. Multiple webs can be created, managed and
  maintained simultaneously. Webs can be updated incrementally when
  individual documents change or new ones are added, with no need to
  rebuild webs from scratch each time.
* Mosaic-compatible. Cyberleaf has been tested with a wide range of
  popular browsers including Mosaics from NCSA, Spyglass, MCOM, Spry,
  and other browsers such as Cello, Lynx, Chimera and Arena.
