 Updated Version: New Essential Step Added

 CHICAGO - April 29, 2009 – Aon Corporation (NYSE: AOC) today issued the following statement by Gisele Norris, DrPH, national director of Aon Healthcare's alternative risk practice:

 "Aon believes the potential business impact of an A/H1N1 swine influenza outbreak is real and must be addressed. Disease in the workplace can cause high incidences of absenteeism, stress and productivity loss. Today's highly mobile, interdependent and interconnected business environment provides a myriad of opportunities for the rapid spread of infectious disease.

"While a longer term goal of updating and expanding crisis management and business continuity plans is essential, Aon offers six immediate steps that are critical right now for businesses to take to protect employees, customers, supply chain partners, additional stakeholders and business assets:

- Determine availability of backup suppliers to ensure supply chain is uninterrupted
- Look at succession planning for all levels of the organization
- Create a process for cascading critical messages to employees
- Develop a protocol to facilitate home working arrangements for employees
- Inform employees of any travel protocols/restrictions in place
- Construct a plan of action should an employee be suspected of having A/H1N1 swine influenza when he/she is at work; similarly, firms must develop a plan of action if an employee is suspected and has been in the workplace three to four days before the onset of symptoms."
