                                            FOR IMMEDIATE RELEASE

                  Lotus Announces Lotus 1-2-3 for Sun

       Sun Workstation Users to Benefit from Spreadsheet Power
                of Best-selling PC Business Software


     NEW YORK, Jan. 17, 1990 -- Lotus Development Corporation today
announced Lotus 1-2-3 for Sun, a family of products based on Lotus
1-2-3 Release 3 and optimized for Sun's three computing platforms: the
SPARC(TM)-based workstations; the Motorola-based Sun-3(TM) line; and
the Intel-based Sun386i(TM). The announcement is the result of a joint
development and marketing agreement announced by Lotus and Sun
Microsystems, Inc. last summer.

     Lotus 1-2-3 for Sun is designed for users who want the
spreadsheet capabilities of 1-2-3, combined with the power of the Sun
workstation. The product integrates 1-2-3's rich user environment with
high-performance Sun workstation capabilities, such as distributed
network services, multiple window support, multi-tasking, and support
for large memory. With Lotus 1-2-3 for Sun, Lotus and Sun are
providing users with a powerful computing platform and the business
application software used by millions of professionals today.

     "The introduction of Lotus 1-2-3 for Sun is a milestone for both
companies and the industry," said Jim Manzi, Lotus president and CEO.
"Users who have made the move to Sun workstations and UNIX(R) will
have the spreadsheet of choice running on this powerful platform.  For
Lotus, 1-2-3 for Sun represents a major step in achieving our goal to
provide applications software that operates across a wide variety of
hardware and operating systems."

    According to Scott McNealy, president and CEO of Sun, important
applications like Lotus 1-2-3 designed specifically for Sun
workstations signals a major trend for 1990. "We're entering an era of
workgroup computing in which professionals will share information via
powerful, low-cost desktop systems like the SPARCstation 1(TM)," said
McNealy. "The increasing availability of shrink-wrapped UNIX
applications like Lotus 1-2-3 for Sun will spur the rise of networked
workstations as a company's principle information source."

      Advanced Spreadsheet Technologies Optimized for Workstation Users

    The new Lotus 1-2-3 for Sun includes the advanced spreadsheet
capabilities introduced in 1-2-3 Release 3, including data analysis
improvements, three-dimensional modeling capabilities, relational
database functionality, improved graphics and file reservation
features. Like 1-2-3 Release 3, Lotus 1-2-3 for Sun will make use of
external data access capabilities provided through Lotus' DataLens
technology.

    "Lotus 1-2-3 and Sun workstations are natural partners for
business," said Frank Moss, vice president of the Lotus Networked
Applications and Systems Division. "Workstations provide tight
integration of computation, graphics and networking that perfectly
complements 1-2-3's superb analysis, presentation and integration
capabilities. Furthermore, 1-2-3 for Sun is a comprehensive
application solution that allows networked users to work together
efficiently and productively."

    Lotus 1-2-3 for Sun is optimized for the Sun computing platforms,
providing users with powerful capabilities available via SunOS(TM),
Sun's UNIX operating system, running under the SunView(TM) windowing
environment. This enables support for distributed network services,
multiple window operation, multi-tasking, support for large memory and
other workstation fea- tures. Users will be able to view up to 26
spreadsheets at a time, using Lotus 1-2-3 for Sun's three-dimensional
perspective mode operating in a SunView window. Lotus 1-2-3 graphs and
multiple spreadsheet files can be viewed through separate windows,
which can be dynamically re-sized or transformed into icons for easy
access.

    Users of Lotus 1-2-3 for Sun will be able to scroll through a
spreadsheet, while simultaneously performing any mixture of the
following: recalculations in the background, executing a macro,
displaying a graph and receiving another worksheet file across a
network. Users can, thus, become more productive and manage a large
flow of applications and data using Lotus 1-2-3 for Sun's
multi-tasking environment.

    Lotus 1-2-3 for Sun also supports the Sun networked environment,
with network security, password protection and locking capabilities at
the file level. Users will find the same familiar user interface as
1-2-3 Release 3 running under DOS and OS/2, and full keystroke
compatibility.  Files and macros are also fully compatible with 1-2-3
Release 3, and users can utilize Sun's industry-standard Network File
System (NFS(TM)) and PC-NFS(TM) to access any file on a network
created by previous versions of 1-2-3 such as 1-2-3 Release 2.01,
1-2-3 Release 2.2 and 1-2-3 Release 3. This compatibility provides
users with the ability to share 1-2-3 data, files and macros in a
heterogeneous or mixed computing environment, while protecting their
investments in applications development and training.

           Lotus to Provide DataLens Toolkit for Lotus 1-2-3 for Sun

    Lotus also announced that it will produce a DataLens Developer
TooLkit for Lotus 1-2-3 for Sun. This product will allow third-party
database vendors and corporate programmers to create drivers that
enable application users to access a wide variety of external data
sources from directly within 1-2-3. Drivers under development for
Lotus 1-2-3 for Sun include Sybase, Ingres, Oracle and Unify. The
DataLens Developer Toolkit is currently in beta testing and will be
available in the second quarter of 1990.

                    Pricing, Availability and Support

    Lotus 1-2-3 for Sun is currently in beta testing and will ship in
the second quarter of 1990.

    Lotus 1-2-3 for Sun is priced at $695 for a Standard Edition,
$995 for a Server Edition and $495 for a Node Edition. The Server
