The Giuliani Group management consulting firm includes a team of senior executives, many of whom served with Mr. Giuliani during his eight years as mayor.

Giuliani Group said it provides corporations with short- and long-term crisis management solutions, aid in the development and implementation of comprehensive crisis operations protocols, and advise on internal and external emergency communications procedures.

"There is tremendous need for corporations to prepare for any type of major crisis: from a physical disaster, to a product recall, to sabotage," said Mr. Giuliani in a statement.

He said the arrangement with the brokerage "will enable companies to tap into the expertise of Giuliani Group's executives, while benefiting from Aon's global reach and corporate consulting knowledge."

"Companies today must prepare for what was previously inconceivable," added Patrick G. Ryan, chairman and chief executive officer of Aon. "Merging our expertise with that of Rudolph Giuliani, whose leadership skills have set a crisis management standard for the world, made perfect sense."

Aon said in 1997 it formed a Special Risks Counter-Terrorism Team that combined both military and insurance experience to provide risk transfer and risk management solutions for clients exposed to the peril of terrorism. The following year, the firm said, it developed risk management and insurance solutions in the event of terrorist use of chemical, biological and radiological agents.

The Aon Crisis Management Practice, offering comprehensive crisis management, crisis communications, and business continuity planning services to corporations worldwide was created in 1999.
