TORONTO, April 18, 2005 - Ceryx, a Toronto-based corporate messaging solutions provider, recently appointed David Penny to the Senior Management team in the new position of Chief Information Officer. Dr. Penny will play an integral role in helping to guide the advancement of Ceryx's core technologies.

CEO of Ceryx, Gus Harsfai commented, "We believe Dr. Penny's success in bringing process, predictability, and high quality to the rigorous software vendor setting will translate well to the service provider setting". "Ceryx has developed a number of proprietary applications that augment our core Exchange service offering that will benefit greatly from Dr. Penny's experience with mission-critical application development."

Previous to Dr. Penny's arrival at Ceryx, he was VP R&D at Electronics Workbench, a software vendor company specializing in Windows-based applications for the electronics design industry. Dr. Penny brought improved quality, on-time delivery, and predictability to that company's software development efforts, which was highly valued by its recent acquirer, National Instruments. Prior to Electronics Workbench, Dr. Penny was an Associate Professor in the Department of Computer Science at the University of Toronto, where he remains an Adjunct Professor.

For five years Dr. Penny was also VP Software Development and CTO at Algorithmics Incorporated, a software vendor selling enterprise risk products to international investment banks. He was a key contributor in growing the company from under $2M in revenue to over $100M. Dr. Penny got his start in the software industry at IBM Toronto Labs, working on the development of an IDE for the C++ language under AIX. Prior to this, he completed his doctorate in Software Engineering at the University of Toronto in 1992.

"Ceryx has shown clear commitment to bringing innovative and technologically advanced solutions to the hosted and managed messaging space," stated Penny. "The messaging expertise at Ceryx is phenomenal and I'm delighted to be able to add my experience in technology management, software and process engineering, and quality assurance into the mix."

Ceryx investors were very excited about the addition of Dr. Penny. "We believe that Ceryx is clearly on the right development path to be able to attract someone with Dr. Penny's depth of experience," stated Bill Di Nardo of Eventi.
