The following is an email message to employees of Union Planters Corporation
from Jackson W. Moore, Chairman, President and Chief Executive Officer of Union
Planters Corporation:


A message from Jack Moore:

It is with great excitement that I announce our agreement to partner with
Regions Financial Corp. in creating a new regional force in banking and
financial services. Union Planters and Regions are joining forces to build an
organization that will create many opportunities for you, our customers,
communities and shareholders. Our combined companies will create the 12th
largest bank holding company in the United States, with total assets of $81
billion. We will now enjoy the No. 1 market position in the mid-South region of
Alabama, Arkansas, Georgia, Louisiana, Mississippi and Tennessee. In addition,
the new company will have significant market share and branch coverage in other
high growth markets.

This move is a smart one because it's a natural evolution in the growth of both
companies. We will expand our customer base from 2.5 to 5.1 million customers in
15 states. In addition, we will nearly double our branch and ATM network with
1,400 banking centers and 1,700 ATMs. This growth will provide greater
convenience and broader choices for customers, expanded opportunities for our
associates and significant benefits for shareholders of both companies. The
strength of this partnership will reinforce common cultures and best practices
in both Regions and Union Planters.

I know that many of you will ask, "What's going to change?" While many of these
details have to be worked out once the legal part of the merger is finalized, we
do know several things already. First, once the merger is completed, our name
will be Regions. Carl E. Jones Jr., Regions' current chairman and CEO, will be
chairman and chief executive officer of the combined company until he retires in
June 2005. He will continue his role as chairman of the board until June 2006.
When the merger occurs, I will be the president of the combined company and
become CEO when Carl retires in June 2005 and assume the additional role of
chairman in June 2006.

We expect the number of associates affected overall will be minimal because of
our limited branch overlap. As I mentioned earlier, we can expect the growth of
the combined company to lead to expanded career opportunities for our
associates.

I am extremely proud of you and the dedication you have given Union Planters.
It's because of you that we have a rich 134-year history of serving our
customers and communities. I look forward to what our two organizations can
accomplish together. I am confident this partnership will create both a new
force in banking and financial services and very bright future.

Associates may call 1-877-375-1346 to hear a message from me regarding this
partnership.
