BIRMINGHAM, Ala., July 11, 2006 - Regions Financial Corp (NYSE: RF). and AmSouth
Bancorporation (NYSE: ASO) today announced a commitment to invest at least $100
billion over the next seven years across the Southeast, Midwest and Texas to
support community development, small business lending and mortgage lending for
low-income communities and borrowers.
      Regions and AmSouth announced their proposed merger on May 25, and the
transaction is expected to close in the fourth quarter of 2006 subject to
shareholder and regulatory approvals. The joint commitment announced today is
contingent on the transaction closing.
      "This is a concrete example of the new Regions' commitment to our
communities and illustrates how combining these two great institutions will
create a stronger future for our communities," said Jackson W. Moore, chairman,
president and CEO of Regions.
      "Both companies have been leaders in community development and we intend
to continue and expand our commitment to strengthening communities, helping
people buy homes, and supporting small businesses, particularly in low- and
moderate-income areas," said Dowd Ritter, chairman, president and CEO of
      Highlights of the commitment include:
           o    At least $50 billion in loans to small businesses;
           o    At least $40 billion in mortgages to low- and moderate-income
                families or families in low- and moderate-income neighborhoods;
           o    At least $10 billion in community development lending and
           o    Formation of the Regions Community Development Corporation to
                provide technical assistance to nonprofit organizations;
           o    Promoting responsible lending practices and fair lending
                initiatives; and
           o    Expanded homeownership and financial literacy programs.

      "The Regions Community Development Corporation will expand our impact
beyond the $100 billion commitment by empowering neighborhood and community
organizations in each of our 16 states to help many more people in low- and
moderate-income areas," Ritter said.
      The new Regions CDC will follow the successful model of the AmSouth
Community Development Corporation, which has supported a broad range of efforts
to expand financing and technical assistance to community organizations and
increase the renovation or construction of affordable housing and revitalization
of low-income communities.
      AmSouth and Regions both have strong histories of supporting their
communities with generous charitable contributions. In 2005, AmSouth, Regions,
and their foundations contributed approximately $14 million to support
education, arts and culture, health and human services, and community and
economic development.
