Trinzic Corporation and Rational Software Corporation Announce Object
Analysis and Design Tool for Client/Server Application Development

Integration of Rational Rose and ObjectPro Provides A Comprehensive
Development Environment

Palo Alto, CA, and Santa Clara, CA, December 6, 1994--Trinzic Corporation
(NASDAQ:TRNZ) and Rational Software Corporation (NASDAQ:RATL) today
announced the availability of Rational Rose/ObjectPro, a new product that
provides the benefits of object-oriented technology to client/server
application development. Rational Rose/ObjectPro is a fully graphical,
object-oriented, software-engineering tool for analysis and design of
client/server applications. It spans the full development cycle from
analysis through implementation by allowing developers to graphically
define and model their applications, and automatically generate source
code and database schemas from their client/server systems.

The Rational Rose/ObjectPro tool is designed to help organizations manage
the [complex] development of client/server applications. Developers of
client/server systems have historically divided applications development
into two domains: the user interface and the database [interaction]. As
applications become more complex and sophisticated, developers are
expanding those domains into three parts: the user interface, the business
object, and the database interaction.

"Many organizations are adopting object-oriented technology for developing
new client/server applications," said Marc Goldberg, marketing manager at
Rational. "These new tools enable developers to use object-oriented
technology to increase productivity, cut development costs, and reduce
time-to-market of new client/server applications. With object technology
and Rational Rose, developers can focus on solving the business issues
rather than worrying about implementation."

Rational Rose/ObjectPro

Rational Rose/ObjectPro automates the production of ObjectPro code.
ObjectPro is Trinzic's new object-oriented development environment that
combines the best aspects of C++ and Smalltalk in a new-generation tool.
Using information in the Rational Rose/ObjectPro class diagrams,
developers can generate ObjectPro source-code files. These files contain
ObjectPro code constructs that correspond to the notation items, classes,
relationships, and adornments that have been defined in the model with
Rose diagrams and specifications. Rational Rose/ObjectPro generates
ObjectPro class, instance, attribute and method structures that define an
ObjectPro application.

"The integration of Rational Rose and ObjectPro yields a joint
modeling/construction environment that makes object developers the clear
winners in adopting and deploying object-oriented solutions," said
Frederick W. Rook, Ph.D., chief technical officer at Trinzic. "We expect
the primary benefit of Rational Rose/ObjectPro to be in the modeling,
development and reuse of business objects."

ObjectPro is a powerful object-oriented development tool for building
robust client/server applications. ObjectPro is an object-oriented system
that provides the productivity and flexibility developers need to build
client/server applications with significant business logic. All
application components are stored as objects so developers can readily
take advantage of the benefits of inheritance and specialization
throughout their applications.

The ObjectPro Object System is fully integrated with ObjectPro libraries,
making it easy to share and reuse all application components--even complex
business models--built in ObjectPro. The ObjectPro Object Language
contains built-in constructs for iteration, assignment, evaluation and
basic operations, and is extensible with libraries. This increases
ease-of-use and decreases the developer's learning curve. ObjectPro also
supports full graphical user interface development, as well as access and
update to a wide variety of databases.

Pricing and Availability

Rational Rose/ObjectPro is available for PCs running Windows or OS/2 for
$1,495 (U.S.). The product is available from both Trinzic at (800)
234-7724 and Rational Software at (800) RAT-1212, and their authorized
distributors. The ObjectPro application development system is also
