Aon Purchases Magnitude's Human Capital Optimization Solution

Chester, NJ (October 28, 2005) - Aon (NYSE: AOC) and Magnitude Information
Systems, Inc. (NASDAQ:MAGY), a human capital optimization solution company, have
announced that Aon Risk Services has purchased Magnitude's ErgoEnterprise(TM)
software for a large segment of its employees using computers.

In 2004 the two firms entered into a strategic alliance, offering Magnitude's
ErgoEnterprise(TM) software as a Human Capital Optimization(TM) Solution for
companies with significant populations of computer users. Aon recognized that
with thousands of its own employees using computers, it fit the profile of a
knowledge worker enterprise and could potentially realize significant
productivity gains utilizing ErgoEnterprise(TM).

Magnitude's Human Capital Optimization solution minimizes the potential for
computer related Repetitive Stress Injuries (RSI's), while simultaneously
reducing fatigue, which significantly increases accuracy. Minimizing lost work
days attributable to computer related RSI's increases knowledge workforce
'up-time". Maximizing the accuracy of the workforce further increases output,
thus compounding the overall productivity gains.

According to the Bureau of Labor Statistics, RSIs cost American business an
estimated 33 billion a year in workers' compensation costs and related costs.
ErgoEnterprise(TM), a patented software solution, tracks keyboard and mouse
activity. It offers a suite of exercises, interactive assessments and surveys as
well as training on proper posture and office ergonomics. The central nervous
system of ErgoEnterprise(TM) is a "data warehouse" which tracks the
human-computer interaction at a "granular level". Real time and historical
computer usage data drive the injury prevention, fatigue minimization and
productivity enhancement algorithms.

Paul Capuzzo, a managing director with Aon Risk Services, states: "We originally
recognized the potential of this solution to help organizations with people
using computers and undertook due-diligence to confirm its effectiveness. We
understood that we also have extensive computer users who can benefit from this
solution, which led to this decision." Mark Chroscielewski, Magnitude SVP of
Business Development commented that outside of the manufacturing sector, it is
rare to find a business that is not looking for productivity gains as a way to
improve their competitive position. Optimizing human capital in the knowledge
worker enterprise will be the new competitive frontier".
