             UMB ANNOUNCES THE RETIREMENT OF R. CROSBY KEMPER JR.


      Kansas City, Mo.  - UMB Financial Corporation [NASDAQ: UMBF] announced
today that R. Crosby Kemper Jr., senior chairman of the board, will retire
from the company and its board of directors on October 29 after 54 years of
service. The UMB Financial Corporation board of directors is expected to
consider an ongoing consulting arrangement with Mr. Kemper at its quarterly
meeting on October 28.

      "My father's dedication to this company and his influence in making it one
of the great independent banks left in the country have had a great impact on
the banking industry and throughout each community where UMB has a presence,"
said Mariner Kemper, chairman and CEO. "His insight, wisdom and leadership are a
constant guide for me as a banker and member of the community. I only hope that
my contemporaries and I can make as positive and lasting of an impression as he
has."

      After serving two years in the U.S. Navy and attending the University of
Missouri in Columbia, Mo., Mr. Kemper began his banking career in 1950. His
first position with what was then called City National Bank and Trust was on the
night shift of the bank's transit department. He later went on to work in nearly
every department within the company before being named executive vice president
in 1957, president in 1959, chairman and CEO in 1971 and senior chairman in
2001.

      "In my 54 years in banking, I have seen the industry evolve considerably.
Yet even throughout these changes I have worked very hard to maintain strong
relationships with customers as my father and grandfather did before me," said
R. Crosby Kemper Jr. "I have been honored to work with many talented peers and
associates throughout my career, and I have the utmost confidence that Mariner
and his management team will successfully carry out UMB's plan for growth and
its tradition of excellent products and services."





      Mr. Kemper's civic involvement has been far reaching over the past 54
years. His community activities have included involvement with: Agricultural
Future of America, Albrecht-Kemper Museum, American Royal Association, Bacchus,
Beta Theta Pi fraternity, Boy Scouts of America, Children's Mercy Hospital,
Heart of America United Way Council, Historic Kansas City Foundation, Jewel
Ball, Kansas City Art Institute, Kansas City Missouri Chamber of Commerce,
