Gregory C. Case
President and Chief Executive Officer
Aon Corporation

Greg Case is president and chief executive officer of Aon Corporation, the leading global
risk, reinsurance and human capital services firm. He is also a member of the company’s
Board of Directors.

Under Case’s leadership, Aon has strengthened its position as a global organization
offering integrated business solutions for clients. Leading the efforts of more than
37,000 colleagues in over 500 offices in 120 countries, Case continues to execute a
three-part strategy focused on delivering distinctive value for clients, attracting the
best talent and achieving operational excellence. Since joining Aon in April 2005, he
has traveled worldwide meeting with clients and colleagues communicating and
sharpening his vision for the organization.

Case also is committed to providing an inclusive environment at Aon. Its diversity
initiatives are leading the way not only in the risk management and human capital
industries, but in the global business community. An example of putting this strategy
into action was the creation of Aon Cornerstone Solutions, an entrepreneurial growth
strategy designed to deliver distinctive value to its clients by developing relationships
with minority-owned partners across the firm’s three main business units. By embracing
the needs of its clients and the talent imperatives of the communities it serves, and by
cascading its diversity strategy throughout the global organization, Aon continues to
focus on hiring the best, building the best, and being the best.

Case has nearly two decades of experience in the insurance and financial services
industries. Before joining Aon, he served on the governing Shareholders’ Committee
at McKinsey & Company, a leading international management consultant, and led
their Global Insurance and Financial Services Practice. Prior to McKinsey, he worked
for the investment banking firm of Piper, Jaffray and Hopwood, and at the Federal
Reserve Bank.

Case holds an MBA from Harvard Business School and graduated summa cum laude
from Kansas State University. He serves on the Boards of The International Insurance
Society, Inc., Children’s Memorial Hospital, Civic Committee of the Commercial Club of
Chicago, Economic Club of Chicago, Chicago Symphony Orchestra, Field Museum of
Natural History, Discover Financial Services Corporation, Financial Services Roundtable,
Peggy Notebaert Nature Museum and St. John’s University School of Risk Management,
