Aon and Magnitude, Inc. To Provide Ergonomic Services for Clients.

CHICAGO -- Strategic alliance will promote use of patented ergonomics software to reduce Repetitive Stress Injury-related costs

Aon (NYSE:AOC) has signed an agreement with Magnitude Information Systems, Inc. (NASDAQ:MAGY), an ergonomics software company, for Aon Risk Services and Magnitude to jointly market Magnitude's ErgoEnterprise software solution to clients of both firms. The ErgoEnterprise software was created to help organizations improve their management of Repetitive Stress Injuries (RSIs) associated with computer use.

According to the Bureau of Labor Statistics, RSIs cost American business an estimated 33 billion a year in workers' compensation.

ErgoEnterprise, a patented product, tracks keyboard and mouse activity independently and offers a system of exercises and ergonomic training. It also centralizes data collection and compliance monitoring by users.

Paul Capuzzo, a managing director with Aon Risk Services, says: "Computer-related musculoskeletal injuries have significantly impacted workers' compensation costs, absenteeism and productivity. Since many of these injuries are reported, treated, and paid for through employer health plans, these costs have proved critical for employers on the non-occupational health side as well. The alliance between Aon and Magnitude will focus on reducing the total cost of this risk for our clients."
