               ON Technology Organizational Changes: Streamlines
                            Sales and Marketing Team

Cambridge, Mass (July 21, 1999)  ON Technology Corporation (Nasdaq: ONTC) today
announced that it has implemented several measures to streamline its senior
sales and marketing staff.  Hans-Till Freiherr von Ruexleben, presently vice
president, professional support, has been promoted to vice president, North
American Sales and Support.  In this position, he replaces Robert Orr, vice
president, North American sales, who has resigned to pursue other non-competing
interests.  Mr. von Ruexleben's new position will also encompass
responsibilities for tactical marketing. Roy Sanford, vice president, worldwide
marketing, also resigned.

"Till brings to his new position an outstanding track record of performance,
both at ON as well as in his prior engagements," said Herman Delatte, ON's
president and CEO.  Before joining ON, Mr. von Ruexleben was the founder and
Managing Director of the German-based csd Software GmbH, where he developed and
successfully marketed what today is ON Technology's cornerstone product--ON
Command CCM.  Under Mr. von Ruexleben's leadership, csd grew to more than 50
employees and revenues in excess of $10 million.  ON Technology acquired csd in
1997.

Before founding csd, Mr. von Ruexleben served as Quality Manager at Siemens
Nixdorf AG, where he consulted leading corporations on network architecture,
backup strategy and network management. Prior to his tenure at Siemens, he was
responsible for establishing the first Client/Server applications and PCs at IDV
(Individuelle Datenverarbeitung) Manager at Bayerische Landesbank in Munich. Mr.
von Ruexleben holds the equivalent of the Master of Computer Science degree.  He
has attended post-graduate classes in Business Administration.

"We strongly feel that Till is optimally qualified to lead ON's North American
sales and support efforts," said Mr. Delatte.  "His experience at csd is
particularly valuable since he has proven that he clearly understands and can
communicate the value that our solution brings to the marketplace.
Furthermore, since 1997, Till has played an indispensable role in ON's global
account management efforts.  We are happy to welcome him in his new capacity."
