Dear Neighbors:

On behalf of Regions and AmSouth, we are excited and proud to announce plans to
combine our two great Alabama-headquartered companies.

With roots dating back to the 1870s, Regions and AmSouth have long traditions of
providing financial services to the great state of Alabama. We will be even
better together, building a stronger financial future for our customers, our
shareholders, our associates, and our communities.

When news like this is announced, it's natural to wonder how it will affect you,
your accounts, and your community. Consider it business as usual. You will
continue to receive the same great service from the same friendly people --
whether the sign out front reads Regions or AmSouth.

Together, we will become one of the 10 largest bank holding companies in the
United States with total assets of nearly $140 billion and approximately 5
million customer households. Our combined resources will allow us to offer our
current customers and future customers more products and solutions than ever
before through our 16-state network of 2,000 branches and 2,800 ATMs.

Regions and AmSouth are two of the largest companies, and largest employers, in
Alabama. Together, we will continue our commitment to strengthening the support
of our associates, our communities, and the hundreds of local companies that
depend on us.

While change always brings challenges, this merger helps us continue Alabama's
rich tradition in financial services. We are confident our customers can look
forward to a stronger financial relationship and that Regions and AmSouth are
better together.
