Filed by Regions Financial Corporation Pursuant to Rule 425 under the Securities Act of 1933 and deemed filed pursuant to Rule 14a-12 of the Securities Exchange Act of 1934 Subject Companies: Union Planters Corporation (Commission File No. 1-10160) Regions Financial Corporation (Commission File No. 0-6159) [Regions Logo][Union Planters Logo] February 23, 2004 REGIONS, UNION PLANTERS NAME NEXT SET OF LEADERS In a move eagerly awaited since the late January announcement of the two companies' planned merger, Regions and Union Planters have organized the top management structure of the new financial powerhouse, assigning geographical responsibilities to regional bank presidents and filling in the blanks on other positions. "Deciding who will lead the 12th largest bank holding company in the United States was not a process we entered into lightly," said Regions Chairman and CEO Carl E. Jones Jr. "We balanced our associates' understandable desire to know something as soon as possible with a careful and deliberate approach to positioning ourselves for future stability and growth - the same kind of approach we plan to use to fill other positions, as well. "Our decisions were made both easier and more difficult by the fact that our two companies share such a strong talent pool," Jones said, referring to current Union Planters CEO Jackson W. Moore. "We congratulate our new team, and would like to invite all associates of both companies to join us in congratulating and supporting them." KEY STEPS IN THE PROCESS Further explaining the process by which key leadership positions throughout the company have been and will continue to be filled, Jones and Moore agreed it was critical that candidates from both companies be considered for each position, and that the Regions and Union Planters human resources departments be heavily involved in each decision. "We've said from the beginning that this is not about personalities and pride, but about customers and common sense," Moore said. "To us, part of applying common sense in this situation means taking a disciplined team approach to filling these roles. As we go forward, senior managers will work with HR on their suggested list of candidates, then the joint transition team Steering Committee will sign off on final decisions." In order to ensure that both companies continue to operate smoothly and focus on their 2004 growth goals as these critical decisions are made, Jones said, the Steering Committee's plan is to provide merger-related updates about every two weeks.
