Corel Acquires Significant Interest in GraphOn

For Immediate Release

GraphOn obtains jBridge technology from Corel to accelerate
completion of true multi-platform thin client/server conduit

Ottawa, Canada – December 18, 1998 – Corel Corporation and
GraphOn ™ Corporation have taken their strategic alliance to a
higher level with a technology transfer that unifies the two
companies’ thin-client/server products.

GraphOn will acquire Corel’s Java ™-based jBridge ™
solution which lets users run 32-bit Windows® applications from
a variety of client platforms. This gives GraphOn the ability to
merge the technology with its powerful GO-Between ™, GO-Global
(tm) and GO-Joe ™ products. The GO products enable UNIX®
applications to run on any desktop, using GraphOn’s highly
efficient thin wire RapidX ™ protocol. GraphOn’s software has
already been licensed by IBM and Sun Microsystems for distribution
with their UNIX-based computers and Java-based thin client

“This is absolutely a win-win situation,” Corel’s president and
chief executive officer, Dr. Michael Cowpland said. “It allows us
to focus on our goal of expanding support for our two great brands
– WordPerfect and CorelDRAW – while benefitting from the synergy of
this alliance and the continued success of jBridge. We are
extremely pleased to continue to share ownership of jBridge through
our stake in GraphOn and to have such an exciting young company now
spearhead the completion of this valuable technology.”

GraphOn president and chief executive officer, Walt Keller said,
“As our companies worked together following our strategic alliance
announced this past August, we realized it made little sense for
two companies to devote separate engineering resources to products
that were naturally made for each other.

“jBridge is the last piece of the puzzle that will give us the
technology to deliver the industry’s only true link from any server
platform to any client platform over any connection,” Keller

Corel will receive a 25% stake in GraphOn, currently a
privately-held company. Earlier this month, GraphOn signed a
non-binding letter of intent to merge with Unity First Acquisition
Corporation, a New York-based company which completed an initial
public offering in 1996 with net proceeds of US $6 million. Upon
completion of the merger, Unity First would acquire GraphOn in
exchange for 6.79 million shares of Unity First common stock and
change its name to GraphOn Corporation. The merger would give
GraphOn and Corel stockholders a combined 78% interest in Unity

In addition, GraphOn is in the process of closing a private
placement with proceeds of up to US $5 million through Spencer
Trask Securities. GraphOn also has the ability to raise an
additional US $20 million through the issue of warrants associated
with the Unity First initial public offering, which on completion
would provide GraphOn up to US $31 million in capital.

As stated earlier this year, Corel is concentrating on its core
product lines – the WordPerfect® family of productivity
applications, including the soon-to-be-released WordPerfect Office
2000, and the CorelDRAW ™ line of graphics and desktop
publishing solutions, which currently enjoy a growing base of
approximately 45 million users. This is in keeping with Corel’s
corporate mandate of delivering performance, value and

As a result, GraphOn will be able to accelerate development of
jBridge combined with its suite of products as a core product line.
GraphOn is committed to fulfilling all contracts and commitments to
third parties.

“We believe we will be the only company able to offer IT
managers the ability to deploy UNIX, Linux and Windows-based
applications to every desktop in their organization and over the
Internet with just the touch of a button through a single
application,” said Keller. “This is simplicity, flexibility and
cost efficiency that we firmly believe nobody else can offer.”

GraphOn is hiring the jBridge development team and will take
over Corel’s New Hampshire operations.

“No jobs will be lost,” said Cowpland. “This is an exciting
opportunity for those employees to play a key role in a rapidly
growing, leading edge company.

Corel Continues to support emerging technologies

Corel intends to further redeploy resources to support the
exciting NetWinder ™ family of Linux-based thin client/thin
server computers and applications such as the recently released
Corel® WordPerfect® 8 for Linux.

“There are immediate opportunities in the Linux field which
require the attention of many of Corel’s hardware and software
engineering resources,” said Cowpland. “Linux is stable and proven
on a wide variety of platforms and Corel has committed to porting
all its major applications to Linux to provide cross platform
