COMPUTONE CORPORATION TO BECOME SYMBIAT, INC.
               CORPORATE NAME CHANGE REFLECTS CUTTING EDGE VISION

ATLANTA   -  June   19,   2002  -   Computone   Corporation   (OTC   BB:   CMPT,
www.computone.com)  announced today that its forward  thinking vision would soon
be reflected in a new  corporate  identity  named  Symbiat,  Inc. The  company's
common stock will trade under the new corporate brand with its respective ticker
symbol.  The  official  name  change and  corresponding  ticker  symbol  will be
announced upon proper regulatory notification and upon the effectuation with the
Delaware  Secretary of State.  Symbiat,  Inc. will be a cutting edge provider of
products, services and outsourced solutions.

The name Symbiat was selected  because it supports the heightened  vision of the
Company,  as well as,  representing  the  corporate  culture of its wholly owned
subsidiary, Multi-User Solutions, Ltd., (www.multiuser.com). Symbiat, pronounced
symo bio at [sim be ot], is a derivative of symbiosis  defined as a cooperative,
mutually  beneficial  relationship  between two people or groups;  organizations
working together for their mutual interest.

"Symbiat Inc. reflects the company's commitment to provide exceptional products,
services and solutions with the highest level of customer care. The expansion by
the company into new markets provides  increased  opportunities  for the company
with new, as well as, existing customers," said Leo Bebeau,  president and chief
executive  officer of Computone  Corporation.  "We chose the name Symbiat  after
extensive  research and  planning.  Through a combined  effort,  the newly named
Symbiat was finalized.  This change represents an important  transformation  and
extension of our growth strategy."

With the  completion of proposed  transactions,  both the parent company and its
subsidiary will operate under the new name.CONSULTING AGREEMENT
