New Folio Infobase Technology Offers Third-Party Developers Ability to
Provide Greater Access to and Adaptability of Information

July 6, 1994, Provo, Utah -- Folio Corporation today announced the
availability of the first three Windows products in the Folio VIEWS 3.1
product family, a new generation of its award-winning infobase software.
The Windows products released today are the Folio VIEWS 3.1 Infobase
Manager, the Folio VIEWS 3.1 Infobase Production Kit (IPK) and the Folio
VIEWS 3.1 Professional Infobase Development Kit (PIDK).

Additional Windows products scheduled for release during the third quarter
are the Folio VIEWS 3.1 Software Developers Kit (SDK) and the Folio VIEWS
3.1 Filter Add-on Pack.

The three products released today have been significantly enhanced with the
addition of Query Templates to simplify searches and Shadow File
Reconciliation for comparing and merging infobase changes with a master
infobase. In addition, the Professional Infobase Development Kit (PIDK)
includes publishing tools such as Rights Management that enable commercial
infobase publishers to directly control access to and use of their
proprietary information and ProPublish for creating custom installation
programs for infobases.

"Today' s release is the first step in Folio' s previously announced
strategy to open its core technology, Folio Infobase Technology (FIT), to
third-party developers," said Tracy Scott, Folio Corporation's president.
"Corporate and commercial developers can now begin empowering infobase
users in dynamic new ways. Folio VIEWS 3.1 gives infobase users options
never before possible for accessing information and adapting it to their
unique needs.

"No other information management solution offers what we do," said Scott.
"With Folio VIEWS 3.1, commercial publishers and people who design
infobases for corporate enterprises now have a set of more robust and
flexible tools to choose from when creating information management
solutions."

Query Templates

Using the Query Template Editor, infobase authors can design custom query
interfaces that allow people to search infobases without knowing anything
about Folio' s search syntax or the content or structure of the infobase
being searched. Using the Query Template Editor, infobase authors can
include any element of the standard VIEWS query dialog -- such as the word
list, results map and search string editing box. Infobase authors can also
create their own custom dialog elements that enable novice users to
conduct complex searches.

For example, a custom query template for an infobase containing magazine
articles might have entry fields labeled Magazine Name, Author's Name and
Subject. Using such a query template, the user would enter any or all of
the following: the name of the magazine, the name of the author or the
subject desired. The resulting query would conduct a search for fields
containing the name of the magazine, a field search for the author' s name
and/or a full-text search in the body of the articles for the subject
requested.

Shadow File Reconciliation

In earlier releases of Folio VIEWS, Folio pioneered the concept of Shadow
Files -- user-created files that act as transparent "overlays" to a master
infobase. Using Shadow Files, people can store personal changes they have
made to an infobase without affecting the original. In the three new Folio
VIEWS 3.1 products, Shadow Files now include the added capabilities of
Append Merge and Smart Merge.

** Append Merge adds all changes in the master infobase to the Shadow File,
enabling instant comparisons between the two infobase files. The Append
Merge displays both the new master information and the shadow file
personalizations. The new master information is listed first; the shadow
file personalizations follow. Both the new information and the shadow file
information are marked with tags that identify them as modifications. The
user can decide, on a record-by-record basis, whether to keep the updated
master, the shadow file personalizations or both.

** Smart Merge applies all of the user' s Shadow File information to the
updated master. The updated master and Shadow File personalizations are
combined through Smart Merge. The new updated information is stored in a
unique field so the user can change the attributes or remove unwanted
information from the Shadow File manually.

Rights Management

Available in only the Folio VIEWS 3.1 Professional Infobase Development Kit
(PIDK), the new Rights Management feature is designed specifically for
commercial electronic publishers. Using Folio's Rights Manager software,
infobase authors can restrict access to their proprietary infobase titles
(on networks, CD ROM or floppy disk) by taking several actions:

- Completely restricting access to selected infobase titles
- Limiting the amount of time a user is permitted to access
  an infobase
- Limiting the number of users who can access an infobase
  concurrently
- Restricting the types of media from which the infobase can
  be accessed
- Granting passwords and other security features

The Rights Manager (which should not be confused with Folio VIEWS' standard
infobase password security features) is targeted at commercial publishers,
OEMs and large corporations.

Availability and Pricing

Three Windows products are now available and two are scheduled for third
quarter, 1994. Corresponding products for DOS and Apple Macintosh will
ship during the fourth quarter of 1994. The Folio VIEWS 3.1 Product Family

of large corporations, commercial publishers, original equipment
manufacturers (OEMs) and independent software vendors (ISVs).
