MINNETONKA, Minn. -- November 20, 2012

UnitedHealth Group (NYSE: UNH) has named Marianne D. Short executive vice
president and chief legal officer, effective January 1, 2013.

Ms. Short, Managing Partner at the firm Dorsey & Whitney LLP, replaces Richard
N. Baer, who is returning to his home in Denver, Colorado, to become General
Counsel at Liberty Media Corporation.

Stephen J. Hemsley, president and chief executive officer of UnitedHealth
Group, said, “Marianne is a highly experienced and wise counselor with deep
legal skills, exceptional business judgment and significant experience in
health care. She is familiar with the complexities of the today’s modern
corporate environment and very familiar with our company and its operations.
Working closely with Marianne for a number of years, we know just how talented
and insightful she is in her work, and she will be an invaluable member of our
leadership team.”

Ms. Short joined Dorsey & Whitney in 1977, after serving as a Special
Assistant Attorney General for the State of Minnesota, following graduation
from Boston College Law School. From 1988-2000, she served as a Minnesota
state appellate judge, authoring more than 900 opinions in virtually every
area of civil and criminal law. After a nearly twelve year judicial career,
Ms. Short returned to Dorsey as a partner in 2000, and was named a Managing
Partner in 2007 and co-Chair of the firm’s Appellate and Health Litigation
practice groups.

Mr. Hemsley said, “We want to thank Rich Baer for his exceptional
contributions to our business and the people who work here, his valuable legal
counsel and his skills in evolving and leading a large and complex corporate
legal and compliance team to an elite level. We have the highest regard for
Rich’s legal and business acumen, personal integrity and generosity of spirit,
the exceptionally hard work he has devoted to our enterprise and his personal
sacrifice spending time away from his family. As Rich returns to Denver to be
with his family, we wish him well in his new endeavors.”
