PRELIMINARY DRAFT DATED JULY 12, 2006, SUBJECT TO COMPLETION

(AMSOUTH LOGO)
 
PROPOSED MERGER — YOUR VOTE IS VERY IMPORTANT
 
We are pleased to report that the boards of directors of Regions Financial Corporation and AmSouth Bancorporation have unanimously approved a strategic merger involving our two companies. Before we can complete the merger, we must obtain the approval of the stockholders of both Regions and AmSouth. We are sending you this document to ask you to vote in favor of adoption of the merger agreement.
 
In the merger, AmSouth will merge with and into Regions, with the combined company retaining the name Regions Financial Corporation. If the merger is completed, AmSouth stockholders will receive 0.7974 shares of Regions common stock for each share of AmSouth common stock held immediately prior to the merger. After completion of the merger, we expect that current Regions stockholders will own approximately 62% of the combined company and AmSouth stockholders will own approximately 38% of the combined company.
 
The exchange ratio in the merger is fixed and will not be adjusted to reflect stock price changes prior to completion of the merger. Based on the closing price of Regions common stock on the New York Stock Exchange on May 24, 2006, the last trading day before public announcement of the merger, the 0.7974 exchange ratio represented approximately [          ] in value for each share of AmSouth common stock. Based on the closing price of Regions common stock on the New York Stock Exchange on [          ], 2006, the latest practicable date before the date of this document, the 0.7974 exchange ratio represented approximately $[     ] in value for each share of AmSouth common stock.
 
You should obtain current market quotations for both Regions common stock and AmSouth common stock. Regions common stock is listed on the New York Stock Exchange under the symbol “RF.” AmSouth common stock is listed on the New York Stock Exchange under the symbol “ASO.”
 
The merger is intended to be generally tax-free to AmSouth stockholders other than with respect to any cash received instead of fractional shares of Regions common stock.
 
We cannot complete the merger unless Regions stockholders and AmSouth stockholders adopt the merger agreement. Regions and AmSouth will each hold a stockholders’ meeting to vote on this merger proposal. Your vote is important. Whether or not you plan to attend your meeting, please take the time to submit your proxy with voting instructions in accordance with the instructions contained in this document. If you do not vote, it will have the same effect as voting against the merger. The places, dates and times of the meetings are as follows:

QUESTIONS AND ANSWERS ABOUT THE MERGER
 
Q: What Am I Being Asked To Vote On?
 
A: Regions stockholders and AmSouth stockholders are each being asked to adopt a merger agreement entered into between Regions Financial Corporation and AmSouth Bancorporation. In the merger, AmSouth will be merged with and into Regions, and Regions will be the surviving corporation.
 
Q: Why Is My Vote Important?
 
A: The affirmative vote of the holders of at least a majority of the outstanding shares of each of Regions and AmSouth is required to adopt the merger agreement. Accordingly, if a Regions stockholder or an AmSouth stockholder fails to vote or abstains, this will have the same effect as a vote against adoption of the merger agreement.
 
Q: What Do I Need To Do Now?
 
A: After you have carefully read this document, indicate on your proxy card how you want your shares to be voted. Then complete, sign, date and mail your proxy card in the enclosed postage paid return envelope as soon as possible. Alternatively, you may vote by telephone or the internet. This will enable your shares to be represented and voted at the Regions special meeting or the AmSouth special meeting, as applicable.
 
Q: If My Shares Are Held In Street Name By My Broker, Will My Broker Automatically Vote My Shares For Me?
 
A: No. Without instructions from you, your broker will not be able to vote your shares. You should instruct your broker to vote your shares, following the directions your broker provides. Please check the voting form used by your broker to see if it offers telephone or internet voting.
 
Q: What If I Fail To Instruct My Broker?
 
A: If you fail to instruct your broker to vote shares held in “street name”, the resulting broker non-vote will have the same effect as a vote against adoption of the merger agreement.
 
Q: Can I Change my Vote?
 
A: Yes. If you have not voted through your broker, there are three ways you can change your vote after you have submitted your proxy (whether by mail, phone or the internet):
 
• First, you may send a written notice to the Corporate Secretary of Regions or AmSouth, as appropriate, stating that you would like to revoke your proxy.
 
• Second, you may complete and submit a new proxy card or vote again by telephone or the internet. Your latest vote actually received by Regions or AmSouth, as the case may be, before the special meeting will be counted, and any earlier votes will be revoked.
 
• Third, you may attend the Regions or AmSouth special meeting, as the case may be, and vote in person. Any earlier proxy will thereby be revoked. However, simply attending the meeting without voting will not revoke an earlier proxy you may have given.
 
If you have instructed a broker to vote your shares, you must follow the directions you receive from your broker in order to change or revoke your vote.
 
Q: If I Am An AmSouth Stockholder, Should I Send In My Stock Certificates Now?
 
A: No. Please do NOT send in your stock certificates at this time. You will be provided at a later date with instructions regarding the surrender of your stock certificates. You should then, prior to the election deadline, send your AmSouth common stock certificates to the exchange agent, together with your completed, signed form of election. There is no need for Regions stockholders to send in or exchange their existing stock certificates at any time in connection with the merger.

SUMMARY
 
This summary highlights selected information from this document. It does not contain all of the information that may be important to you. We urge you to read carefully the entire document and the other documents to which we refer in order to fully understand the merger and the related transactions. In addition, we incorporate by reference into this document important business and financial information about Regions and AmSouth. You may obtain the information incorporated by reference into this document without charge by following the instructions in the section entitled “Where You Can Find More Information” on page [  ]. Each item in this summary refers to the page of this document on which that subject is discussed in more detail.
 
The Merger (Page [  ])
 
We encourage you to read the merger agreement, which is attached as Annex A to this document. The merger agreement provides that AmSouth will merge with and into Regions, with Regions as the surviving company. Each share of AmSouth common stock outstanding prior to the merger will automatically be converted in the merger into 0.7974 shares of Regions common stock. The combined company will retain the name Regions Financial Corporation and its common stock will continue to trade on the New York Stock Exchange, or the “NYSE”, under the symbol “RF”.
 
Exchange Ratio in the Merger (Page [  ])
 
Upon completion of the merger, each AmSouth stockholder will receive 0.7974 shares of Regions common stock for each share of AmSouth common stock held immediately prior to the merger. We sometimes refer to this ratio as the “exchange ratio.” The aggregate number of shares of Regions common stock to which an AmSouth stockholder will be entitled upon completion of the merger will equal 0.7974 multiplied by the number of shares of AmSouth common stock held by that AmSouth stockholder. However, Regions will not issue any fractional shares. AmSouth stockholders entitled to a fractional share will instead receive an amount in cash equal to the fraction of a whole share of Regions common stock to which such stockholder would otherwise be entitled multiplied by the closing sale price of Regions common stock on the trading day immediately prior to the date on which the merger is completed. As an example, a holder of 100 shares of AmSouth common stock would receive 79 shares of Regions common stock and an amount of cash equal to the product of .74 and the Regions closing price on the trading day immediately prior to the date on which the merger is completed.
 
The exchange ratio is a fixed ratio. Therefore, the number of shares of Regions common stock to be received by holders of AmSouth common stock in the merger will not change if the trading price of Regions common stock or AmSouth common stock changes between now and the time the merger is completed.
 
Upon completion of the merger, we expect that Regions stockholders will own approximately 62% of the combined company and former AmSouth stockholders will own approximately 38% of the combined company.
 
The market prices of both Regions common stock and AmSouth common stock will fluctuate prior to the merger. You should obtain current stock price quotations for Regions common stock and AmSouth common stock.
 
Regions’ Board of Directors Unanimously Recommends that You Vote “FOR” the Adoption of The Merger Agreement (Page [  ])
 
Regions’ board of directors believes that the merger is in the best interests of Regions and its stockholders and has unanimously approved the merger agreement. For the factors considered by the Regions board of directors in reaching its decision to approve the merger agreement, see the section entitled “The Merger — Regions’ Reasons for the Merger; Recommendation of Regions’ Board of Directors.” Regions’ board of directors unanimously recommends that Regions stockholders vote “FOR” the adoption of the merger agreement.

AmSouth’s Board of Directors Unanimously Recommends that You Vote “FOR” the Adoption of the Merger Agreement (Page [  ])
 
AmSouth’s board of directors believes that the merger is in the best interests of AmSouth and its stockholders and has unanimously approved the merger agreement. For the factors considered by the AmSouth board of directors in reaching its decision to approve the merger agreement, see the section entitled “The Merger — AmSouth’s Reasons for the Merger; Recommendation of AmSouth’s Board of Directors.” AmSouth’s board of directors unanimously recommends that AmSouth stockholders vote “FOR” the adoption of the merger agreement.
 
Regions’ Financial Advisor Has Provided an Opinion to the Regions Board of Directors as to the Fairness of the Exchange Ratio, from a Financial Point of View, to Regions (Page [  ])
 
In deciding to approve the merger, the Regions board of directors considered the opinion of its financial advisor, Merrill Lynch, Pierce, Fenner & Smith Incorporated, which was given to the Regions board of directors on May 24, 2006, that, as of the date of such opinion and based upon and subject to the assumptions, qualifications and limitations described in the opinion, the exchange ratio pursuant to the merger agreement was fair from a financial point of view to Regions. A copy of this opinion is attached to this document as Annex D. Regions stockholders should read the opinion completely and carefully to understand the assumptions made, matters considered and limitations on the review undertaken by Merrill Lynch in providing its opinion.
 
AmSouth’s Financial Advisor Has Provided an Opinion to the AmSouth Board of Directors as to the Fairness of the Exchange Ratio, from a Financial Point of View, to AmSouth Stockholders (Page [  ])
 
In deciding to approve the merger, the AmSouth board of directors considered the opinion of its financial advisor, Goldman, Sachs & Co., which was given to the AmSouth board of directors on May 24, 2006, that, as of the date of such opinion, the exchange ratio pursuant to the merger agreement was fair from a financial point of view to the holders of AmSouth common stock. A copy of this opinion is attached to this document as Annex E. AmSouth stockholders should read the opinion completely and carefully to understand the assumptions made, matters considered and limitations of the review undertaken by Goldman Sachs in providing its opinion.
 
Certain Executive Officers and Directors Have Financial Interests in the Merger (Pages [  ] and [  ])
 
Certain executive officers and directors of Regions and AmSouth have financial interests in the merger in addition to their interests as stockholders. In the case of AmSouth, these interests include rights of executive officers under change of control agreements with AmSouth, rights under stock-based benefit programs and awards of AmSouth, rights under supplemental retirement benefit and thrift plans, and, in the case of C. Dowd Ritter, Chairman of the Board, President and Chief Executive Officer of AmSouth, rights under two split-dollar life insurance agreements with AmSouth. The AmSouth board of directors was aware of, and the Regions board of directors was notified of, these interests. Both boards considered these interests, among other matters, in approving the merger. Jackson W. Moore, Chairman, President and Chief Executive Officer of Regions, entered into an employment agreement superseding his existing agreement, which will become effective as of the completion of the merger, as more fully described under “The Merger — Interests of Regions’ Management in the Merger.” The Regions board of directors was aware of, and the AmSouth board of directors was notified of, these interests. Both boards considered these interests, among other matters, in approving the merger agreement.
 
Board of Directors and Management of Regions Following the Merger (Page [  ])
 
Upon completion of the merger, the board of directors of Regions will consist of twelve current directors of Regions designated by Regions (plus up to one additional director with the mutual agreement of Regions and AmSouth), and nine current directors of AmSouth designated by AmSouth (plus up to one additional director with the mutual agreement of Regions and AmSouth).
 
Immediately following the merger, Jackson W. Moore, Chairman, President and Chief Executive Officer of Regions, will serve as Chairman of the Board of Regions, and C. Dowd Ritter, Chairman of the Board, President and Chief Executive Officer of AmSouth, will serve as President and Chief Executive Officer of Regions.

We estimate, as of the date of this document, that we will need to make divestitures of branches in 15 markets with aggregate deposits of approximately $2.2 to $2.5 billion, and related loans and securities, in order to obtain approval of the merger by the Federal Reserve Board, although this is a preliminary estimate and the actual divestitures we will need to make may be more or less than this estimate. We also have made or will make filings with various state banking departments, antitrust authorities and several other regulatory agencies as well.
 
Although we currently believe we should be able to obtain these regulatory approvals in a timely manner, we cannot be certain when or if we will obtain them or, if obtained, whether they will contain terms, conditions or restrictions not currently contemplated that will be detrimental to the combined company after the completion of the merger. As a matter of Federal Reserve Board policy, we must enter into written agreements for the divested branches before Federal Reserve Board approval can be obtained for the merger.
 
Conditions to Completion of the Merger (Page [  ])
 
As more fully described in this document and the merger agreement, the completion of the merger depends on a number of conditions being satisfied or waived, including:
 
  •  adoption of the merger agreement by the stockholders of both companies;
 
  •  receipt of governmental and regulatory approvals required to complete the merger, which approvals must not be subject to any condition that would have a material adverse effect on the combined company after the completion of the merger;
 
  •  there being no injunction, decree, or order enjoining or prohibiting the merger;
 
  •  listing of the Regions common stock to be issued in the merger on the NYSE;
 
  •  the receipt by each party of an opinion of their respective counsel that the merger will constitute a reorganization within the meaning of Section 368(a) of the Internal Revenue Code;
 
  •  the accuracy of the other party’s representations and warranties, subject to the material adverse effect standard in the merger agreement; and
 
  •  the other party having performed and complied with its covenants in the merger agreement in all material respects.
 
We cannot be certain when, or if, the conditions to the merger will be satisfied or waived, or that the merger will be completed.
 
Termination of the Merger Agreement (Page [  ])
 
We may agree to terminate the merger agreement before completing the merger, even after adoption of the merger agreement by our stockholders, if each of our boards of directors agrees to terminate.
 
In addition, either of us may decide to terminate the merger agreement, even after adoption of the merger agreement by our stockholders, in various circumstances, including the following:
 
  •  if there is an uncured breach of the other party’s representations, warranties or covenants that would result in the failure of the related closing conditions;
 
  •  if any of the required regulatory approvals are denied and the denial is final and nonappealable;
 
  •  if the other party fails to recommend approval of the merger to its stockholders, breaches its non-solicitation covenant or its obligation to use reasonable best efforts to obtain its stockholders’ approval, negotiates with a third party regarding a competing transaction and the negotiations do not cease within 20 business days, or endorses a competing transaction;
 
  •  if the merger has not been completed by May 31, 2007; or

  •  if a party’s stockholders fail to adopt the merger agreement, and that party substantially engages in bad faith in breach of its obligation to restructure the transaction and/or to re-submit it to stockholders for approval.
 
AmSouth Granted a Stock Option to Regions
 
To induce Regions to enter into the merger agreement, AmSouth granted Regions an option to purchase up to 69,027,842 shares of AmSouth common stock at a price per share equal to the lesser of $28.90 or the closing sale price of AmSouth common stock on the trading day immediately preceding the exercise date; however, in no case may Regions acquire more than 19.9% of the outstanding shares of AmSouth common stock under this stock option agreement. Regions cannot exercise the option unless specified triggering events occur. These events generally relate to business combinations or acquisition transactions involving AmSouth and a third party.
 
The option could have the effect of discouraging a company from trying to acquire AmSouth prior to completion of the merger or termination of the merger agreement. Upon the occurrence of certain triggering events, AmSouth may be required to repurchase the option and any shares of AmSouth common stock purchased under the option at a predetermined price, or Regions may choose to surrender the option to AmSouth for a cash payment of approximately $344 million. In no event will the total profit received by Regions with respect to this option exceed approximately $393 million.
 
The AmSouth stock option agreement is attached to this document as Annex B.

SELECTED COMBINED CONDENSED CONSOLIDATED UNAUDITED
PRO FORMA FINANCIAL DATA
(DOLLARS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)
 
The following table shows information about our financial condition and operations, including per share data and financial ratios, after giving effect to the merger. This information is called pro forma information in this document. The table sets forth the information as if the merger had become effective March 31, 2006, with respect to financial condition, and at the beginning of each of the periods presented, with respect to operations data. The pro forma data in the tables assume that the merger is accounted for as an acquisition by Regions of AmSouth using the purchase method of accounting. The pro forma financial information includes adjustments to record the assets and liabilities of AmSouth at their estimated fair values and is subject to further adjustment as additional information becomes available and as additional analyses are performed. The pro forma statements of operations do not include intangibles which may be incurred subsequent to the merger. This table should be read in conjunction with, and is qualified in its entirety by, the historical financial statements, including the notes thereto, of Regions and AmSouth which are incorporated by reference in this document and the more detailed pro forma financial information, including the notes thereto, appearing elsewhere in this document. See “Where You Can Find More Information” on page [  ] and “Pro Forma Financial Information” on page [  ].
 
We anticipate that the merger will provide the combined company with financial benefits that include reduced operating expenses. The pro forma information does not reflect the benefits of expected cost savings, opportunities to earn additional revenue or the costs and amortization referred to in the preceding paragraph and, accordingly, does not attempt to predict or suggest future results. It also does not necessarily reflect what the historical results of the combined company would have been had our companies been combined during these periods.
 
For purposes of the “Pro Forma Financial Information” on page [  ], we have made certain assumptions regarding divestitures we will need to make in order to obtain approval of the merger by the Federal Reserve Board. These assumptions, as well as estimates of the foregone interest from these transactions, are included in the pro forma financial information upon which the information in the following table is based. The adjustments recorded for these divestitures on the merger date could vary significantly from the pro forma adjustments included herein depending on final regulatory divestiture requirements and changes in interest rates.

COMPARATIVE PER SHARE DATA
 
The following table sets forth for Regions common stock and AmSouth common stock certain historical, pro forma and pro forma-equivalent per share financial information. The pro forma and pro forma equivalent per share information gives effect to the merger as if the merger had been effective on December 31, 2005. The pro forma data in the tables assumes that the merger is accounted for as an acquisition by Regions of AmSouth using the purchase method of accounting. See “The Merger — Accounting Treatment” on page [  ]. The information in the following table is based on, and should be read together with, the historical financial information that we have presented in our prior filings with the Securities and Exchange Commission and the pro forma financial information that appears elsewhere in this document. See “Where You Can Find More Information” on page [  ] and “Pro Forma Financial Information” on page [  ].
 
We anticipate that the merger will provide the combined company with financial benefits that include reduced operating expenses. The pro forma information does not reflect the benefits of these expected cost savings, opportunities to earn additional revenue, the impact of restructuring and merger-related costs or the amortization of certain intangibles and, accordingly, does not attempt to predict or suggest future results. It also does not necessarily reflect what the historical results of the combined company would have been had our companies been combined during these periods.
 
For purposes of the “Pro Forma Financial Information” on page [  ], we have made certain assumptions regarding divestitures we will need to make in order to obtain approval of the merger by the Federal Reserve Board. These assumptions, as well as estimates of the foregone interest from these transactions, are included in the pro forma financial information upon which the information in the following table is based. The adjustments recorded for these divestitures on the merger date could vary significantly from the pro forma adjustments included herein depending on final regulatory divestiture requirements and changes in interest rates.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS
 
This document contains or incorporates by reference a number of forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 regarding Regions and AmSouth and may include statements for the period following the completion of the merger. You can find many of these statements by looking for words such as “plan,” “believe,” “expect,” “intend,” “anticipate,” “estimate,” “project,” “potential” or other similar expressions. Such statements include, but are not limited to, statements about the benefits of the merger, including future financial and operating results, and Regions’ and AmSouth’s plans, objectives, expectations and intentions. Such statements involve risks and uncertainties that may cause results to differ materially from those set forth in these statements.
 
The ability of Regions and AmSouth to predict results or the actual effects of its plans and strategies is inherently uncertain and the merger itself creates additional uncertainty. Accordingly, actual results may differ materially from anticipated results. The following factors, among others, could cause actual results to differ materially from those set forth in the forward-looking statements:
 
  •  the risk that the businesses of Regions and/or AmSouth in connection with the merger will not be integrated successfully or such integration may be more difficult, time-consuming or costly than expected;
 
  •  expected revenue synergies and cost savings from the merger may not be fully realized or realized within the expected time frame;
 
  •  revenues following the merger may be lower than expected;
 
  •  customer and employee relationships and business operations may be disrupted by the merger;
 
  •  the ability to obtain required governmental and stockholder approvals, and the ability to complete the merger on the expected timeframe;
 
  •  the effect of branch divestitures which we expect will be required in overlapping markets in connection with obtaining necessary regulatory approvals;
 
  •  possible changes in economic and business conditions;
 
  •  the existence or exacerbation of general geopolitical instability and uncertainty;
 
  •  the ability of Regions and AmSouth to integrate recent acquisitions and attract new customers;
 
  •  possible changes in monetary and fiscal policies, and laws and regulations;
 
  •  the effects of easing of restrictions on participants in the financial services industry;
 
  •  the cost and other effects of legal and administrative cases;
 
  •  possible changes in the credit worthiness of customers and the possible impairment of collectibility of loans;
 
  •  the effects of changes in interest rates and other risks and factors identified in each company’s filings with the SEC; or
 
  •  the effects of weather and natural disasters such as hurricanes.
 
Because such forward-looking statements are subject to assumptions and uncertainties, actual results may differ materially from those expressed or implied by such forward-looking statements. Regions stockholders and AmSouth stockholders are cautioned not to place undue reliance on such statements, which speak only as of the date of this document or the date of any document incorporated by reference.
 
All subsequent written and oral forward-looking statements concerning the merger or other matters addressed in this document and attributable to Regions, AmSouth or any person acting on their behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this section. Neither Regions nor AmSouth undertakes any obligation to update such forward-looking statements to reflect events or circumstances after the date of this document or to reflect the occurrence of unanticipated events.

THE REGIONS SPECIAL MEETING
 
Date, Time and Place
 
The Regions special meeting will be held on [          ], 2006 at 10:00 a.m. local time at Regions Bank Operations Center, 201 Milan Parkway, Birmingham, Alabama, 35209.
 
Matters to Be Considered
 
At the Regions Special Meeting, Regions stockholders will be asked to:
 
•  adopt the merger agreement;
 
  •  approve the adjournment of the Regions special meeting, if necessary or appropriate, to solicit additional proxies; and
 
  •  transact such other business as may properly come before the special meeting or any adjournment or postponement of the meeting.
 
Proxies
 
You should complete and return the proxy card accompanying this document to ensure that your vote is counted at the Regions special meeting, regardless of whether you plan to attend the Regions special meeting. If you are a registered stockholder (that is, you hold stock certificates registered in your own name), you may also vote by telephone or through the internet, by following the instructions described on your proxy card. If your shares are held in nominee or “street name” you will receive separate voting instructions from your broker or nominee with your proxy materials. Although most brokers and nominees offer telephone and internet voting, availability and specific processes will depend on their voting arrangements. You can revoke the proxy at any time before the vote is taken at the Regions special meeting by submitting to Regions’ corporate secretary written notice of revocation or a properly executed proxy of a later date, or by attending the Regions special meeting and voting in person. Written notices of revocation and other communications about revoking Regions proxies should be addressed to:
 
Regions Financial Corporation
417 North 20th Street
Birmingham, Alabama 35203
Attention: R. Alan Deer
Executive Vice President, General Counsel and Corporate Secretary
 
If your shares are held in street name, you should follow the instructions of your broker regarding the revocation of proxies.
 
All shares represented by valid proxies that we receive through this solicitation, and that are not revoked, will be voted in accordance with the instructions on the proxy card. If you make no specification on your proxy card as to how you want your shares voted before signing and returning it, your proxy will be voted “FOR” adoption of the merger agreement and “FOR” the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies. The Regions board of directors is currently unaware of any other matters that may be presented for action at the Regions special meeting. If other matters properly come before the Regions special meeting, or at any adjournment or postponement thereof, we intend that shares represented by properly submitted proxies will be voted, or not voted, by and at the discretion of the persons named as proxies on the proxy card.
 
Solicitation of Proxies
 
We will bear the entire cost of soliciting proxies from you. In addition to solicitation of proxies by mail, we will request that banks, brokers and other record holders send proxies and proxy material to the beneficial owners of Regions common stock and secure their voting instructions, if necessary. We will reimburse the record holders for their reasonable expenses in taking those actions. We have also made arrangements with D.F. King & Co., Inc. to assist us in soliciting proxies and have agreed to pay them $15,000 plus reasonable expenses for these services. If

Table of Contents

necessary, we may also use several of our regular employees, who will not be specially compensated, to solicit proxies from Regions stockholders, either personally or by telephone, telegram, facsimile or letter.
 
Record Date
 
The Regions board of directors has fixed the close of business on [          ], 2006 as the record date for determining the Regions stockholders entitled to receive notice of and to vote at the Regions special meeting. At that time, [          ] shares of Regions common stock were outstanding, held by approximately [          ] holders of record. As of the record date, directors and executive officers of Regions and their affiliates had the right to vote [          ] shares of Regions common stock as of the record date, representing less than [          ]% of the shares entitled to vote at the Regions special meeting. Regions currently expects that its directors and executive officers will vote such shares “FOR” adoption of the merger agreement;
 
Quorum and Vote Required
 
The presence, in person or by properly executed proxy, of the holders of a majority of the outstanding shares of Regions common stock is necessary to constitute a quorum at the special meeting. Abstentions and broker non-votes will be counted solely for the purpose of determining whether a quorum is present.
 
Adoption of the merger agreement requires the affirmative vote of the holders of a majority of the outstanding shares of Regions common stock entitled to vote at the Regions special meeting. Approval of the proposal relating to the adjournment of the special meeting, if necessary or appropriate, to solicit additional proxies requires that the votes cast in favor of the proposal exceed the votes cast in opposition. You are entitled to one vote for each share of Regions common stock you held as of the record date.
 
Because the affirmative vote of the holders of a majority of the outstanding shares of Regions common stock entitled to vote at the Regions special meeting is required to adopt the merger agreement, the failure to vote by proxy or in person will have the same effect as a vote against the merger agreement. Abstentions and broker non-votes also will have the same effect as a vote against the merger. Accordingly, the Regions board of directors urges Regions stockholders to complete, date and sign the accompanying proxy card and return it promptly in the enclosed postage-paid envelope, or to vote by telephone or the internet.
 
Abstentions, failures to vote and broker non-votes will have no effect on the vote to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies.
 
Participants in the Regions’ 401(k) and Other Plans
 
Participants in Regions’ 401(k) plan, the EquiServe Investment Plan and the Directors Stock Investment Plan, please note that the enclosed proxy card also constitutes the voting instruction form for shares allocated to you under the plan and covers all shares you are entitled to vote under the plan or plans, in addition to shares you may hold directly. Signing and returning the proxy card, or voting by telephone or on the internet as explained below, will enable voting of all shares, including those held in such plans.
 
Voting by Telephone or the Internet
 
Many stockholders of Regions have the option to submit their proxies or voting instructions electronically by telephone or the internet instead of submitting proxies by mail on the enclosed proxy card. Please note that there are separate arrangements for using the telephone and the internet depending on whether your shares are registered in Regions’ stock records in your name or in the name of a brokerage firm or bank. Regions stockholders should check their proxy card or the voting instructions forwarded by their broker, bank or other holder of record to see which options are available.
 
Regions holders of record may submit their proxies:
 
  •  by telephone, by calling the toll-free number indicated on their proxy card and following the recorded instructions; or
 
  •  through the internet, by visiting the website indicated on their proxy card and following the instructions.

Matters to Be Considered
 
At the AmSouth special meeting, the AmSouth stockholders will be asked to:
 
  •  adopt the merger agreement;
 
  •  approve the adjournment of the AmSouth special meeting, if necessary or appropriate, to solicit additional proxies; and
 
  •  transact such other business as may properly come before the special meeting or any adjournment or postponement of the meeting.

You can revoke the proxy at any time before the vote is taken at the special meeting by submitting to AmSouth’s corporate secretary written notice of revocation or a properly executed proxy of a later date, or by attending the special meeting and voting in person. Written notices of revocation and other communications about revoking AmSouth proxies should be addressed to:
 
AmSouth Bancorporation
1900 Fifth Avenue North
Birmingham, Alabama 35203
Attention: John D. Buchanan
Executive Vice President,
General Counsel and Corporate Secretary
 
If your shares are held in street name, you should follow the instructions of your broker regarding the revocation of proxies.
 
All shares represented by valid proxies that we receive through this solicitation, and that are not revoked, will be voted in accordance with the instructions on the proxy card. If you make no specification on your proxy card as to how you want your shares voted before signing and returning it, your proxy will be voted “FOR” the adoption of the merger agreement and “FOR” the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies. The AmSouth board of directors is currently unaware of any other matters that may be presented for action at the special meeting. If other matters properly come before the special meeting, or at any adjournment or postponement thereof, we intend that shares represented by properly submitted proxies will be voted, or not voted, by and at the discretion of the persons named as proxies on the proxy card.
 
AmSouth stockholders should not send stock certificates with their proxy cards. If the merger is completed, AmSouth stockholders will need to exchange their current stock certificates for Regions stock certificates. Upon completion of the merger, former AmSouth stockholders will be mailed a transmittal form with instructions on how to exchange their AmSouth stock certificates for Regions stock certificates.

Solicitation of Proxies
 
We will bear the entire cost of soliciting proxies from you. In addition to solicitation of proxies by mail, we will request that banks, brokers, and other record holders send proxies and proxy material to the beneficial owners of AmSouth common stock and secure their voting instructions, if necessary. We will reimburse the record holders for their reasonable expenses in taking those actions. We have also made arrangements with Innisfree M&A Incorporated to assist us in soliciting proxies and have agreed to pay them a fee not expected to exceed $75,000 plus reasonable expenses for these services. If necessary, we may use several of our regular employees, who will not be specially compensated, to solicit proxies from AmSouth stockholders, either personally or by telephone, telegram, facsimile or letter.
 
Record Date
 
The AmSouth board of directors has fixed the close of business on [          ], 2006 as the record date for determining the AmSouth stockholders entitled to receive notice of and to vote at the AmSouth special meeting. At that time, [          ] shares of AmSouth common stock were outstanding, held by approximately [     ] holders of record. As of the record date, directors and executive officers of AmSouth and their affiliates had the right to vote [          ] shares of AmSouth common stock, representing less than [     ]% of the shares entitled to vote at the AmSouth special meeting. AmSouth currently expects that its directors and executive officers will vote such shares “FOR” adoption of the merger agreement.
 
Quorum and Vote Required
 
The presence, in person or by properly executed proxy, of the holders of a majority of the outstanding shares of AmSouth common stock is necessary to constitute a quorum at the AmSouth special meeting. Abstentions and broker non-votes will be counted for the purpose of determining whether a quorum is present.
 
Adoption of the merger agreement requires the affirmative vote of the holders of a majority of the outstanding shares of AmSouth common stock entitled to vote at the AmSouth special meeting. Approval of the proposal relating to the adjournment of the special meeting, if necessary or appropriate, to solicit additional proxies requires that the votes cast in favor of the proposal exceed the votes cast in opposition. You are entitled to one vote for each share of AmSouth common stock you held as of the record date.
 
Because the affirmative vote of the holders of a majority of the outstanding shares of AmSouth common stock entitled to vote at the AmSouth special meeting is required to adopt the merger agreement, the failure to vote by proxy or in person will have the same effect as a vote against the merger agreement. Abstentions and broker non-votes also will have the same effect as a vote against the merger. Accordingly, the AmSouth board of directors urges AmSouth stockholders to complete, date, and sign the accompanying proxy card and return it promptly in the enclosed postage-paid envelope or to vote by telephone or the internet.
 
Abstentions, failures to vote and broker non-votes will have no effect on the vote on the adoption of the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies.
 
Participants in Certain AmSouth Plans
 
Participants in AmSouth’s Direct Stock Purchase and Dividend Reinvestment Plan (the “DRP”) and/or AmSouth employees who participate in the AmSouth Stock Fund of the AmSouth Thrift Plan will find that the enclosed proxy card or electronic voting instruction shows the total of the number of any shares held by them in their own names (but not in street name through a broker) as well as those shares, including fractions of shares, held on their behalf by the agent for the DRP and/or the trustee for the Thrift Plan. Voting in one of the ways described above will allow voting of all shares, including those held by the DRP agent and the trustee for the Thrift Plan. Without instructions the trustee for the Thrift Plan will not be able to vote shares it holds with respect to the adoption of the merger agreement. Failure to instruct the trustee will have the same effect as a vote against adoption of the merger agreement.
 
Voting by Telephone or the Internet
 
Many stockholders of AmSouth have the option to submit their proxies or voting instructions electronically by telephone or the internet instead of submitting proxies by mail on the enclosed proxy card. Please note that there are


18


Table of Contents

separate arrangements for using the telephone and the internet depending on whether your shares are registered in AmSouth’s stock records in your name or in the name of a brokerage firm or bank. AmSouth stockholders should check their proxy card or the voting instructions forwarded by their broker, bank or other holder of record to see which options are available.
 
AmSouth holders of record may submit their proxies:
 
  •  by telephone, by calling the toll-free number indicated on their proxy card and following the recorded instructions; or
 
  •  through the internet, by visiting the website indicated on their proxy card and following the instructions.
 
THE MERGER
 
The following discussion contains material information pertaining to the merger. This discussion is a summary only and may not contain all of the information that is important to you. A copy of the merger agreement is attached to this document as Annex A and is incorporated by reference herein. We encourage you to read and review the merger agreement as well as the discussion in this document.
 
Structure
 
The Regions board of directors and the AmSouth board of directors have each unanimously approved the merger agreement, which provides for the merger of AmSouth with and into Regions, with Regions as the surviving corporation. Each share of AmSouth common stock outstanding prior to the merger will be converted, upon completion of the merger, into the right to receive 0.7974 shares of the common stock of Regions. We sometimes refer to this ratio as the “exchange ratio.” Shares of AmSouth common stock issued and outstanding immediately prior to the merger will be cancelled.
 
Background of the Merger
 
Each of Regions’ and AmSouth’s board of directors has from time to time engaged with senior management in strategic reviews, and has considered ways to enhance its company’s performance and prospects in light of competitive and other relevant developments. These strategic reviews have focused on, among other things, the business environment facing financial institutions generally, as well as conditions and ongoing consolidation in the financial services industry, and from time to time have focused on the possibility of a merger with another major Alabama-based banking organization. For each company, these reviews have also included periodic discussions with respect to potential transactions that would further its strategic objectives, and the potential benefits and risks of those transactions.
 
Jackson W. Moore, Chairman, President and Chief Executive Officer of Regions, and C. Dowd Ritter, Chairman, President and Chief Executive Officer of AmSouth, have known each other for several years, and periodically have spoken about their respective companies and the banking industry at industry meetings. In late 2005, Mr. Moore and Mr. Ritter met in a social setting and during the course of conversation discussed general industry trends and developments regarding their respective companies.
 
In January 2006, the Regions board of directors held a regular meeting at which they discussed generally strategic objectives and the financial services industry, and during the course of this strategic review, the Regions board of directors discussed AmSouth and the preliminary conversation between Mr. Moore and Mr. Ritter. At this meeting, the board authorized Mr. Moore to engage in exploratory discussions with Mr. Ritter regarding a possible strategic transaction between the two companies. Subsequent to this meeting, starting in February 2006, Mr. Moore and Mr. Ritter spoke regarding the possibility of a strategic merger of the two companies.
 
Based on preliminary mutual interest in the potential merits of a possible strategic transaction, exploratory discussions between the two companies concerning the framework for a possible transaction that would be mutually acceptable followed starting in mid-March 2006. These discussions focused on a strategic at-market merger, with fairly apportioned board and management representation and participation in the combined company and a “best-of-breed” approach to key management positions, as likely the most promising strategic direction for each company. Mr. Moore periodically apprised members of the Regions board of directors of the status of his discussions with Mr. Ritter. At a regular meeting of the Regions board of directors held in April 2006, Mr. Moore

Table of Contents

described to the Regions board of directors his preliminary discussions with Mr. Ritter regarding a combination of Regions and AmSouth. The Regions board of directors recommended that Mr. Moore continue to pursue his discussions with Mr. Ritter. Thereafter, at a regular meeting of the Regions board of directors held in May 2006, Mr. Moore updated the board on the status of the preliminary discussions, and there was a consensus among the Regions directors that pursuing a transaction along the lines that had been outlined would be an attractive strategic and financial transaction for Regions to pursue. During the same period, Mr. Ritter periodically apprised members of the AmSouth board of directors of the status of his discussions with Mr. Moore. At a regularly scheduled AmSouth board of directors meeting held in April 2006, Mr. Ritter described to the AmSouth board of directors his preliminary discussions with Mr. Moore regarding a combination of AmSouth and Regions. The AmSouth board of directors recommended that Mr. Ritter continue to pursue his conversations with Mr. Moore and believed that a merger generally along these lines represented a potentially unique strategic and financial opportunity. In connection with these discussions, AmSouth retained Goldman Sachs as its outside financial advisor and Sullivan & Cromwell LLP as its outside legal advisor, and Regions retained Merrill Lynch as its outside financial advisor and Wachtell, Lipton, Rosen & Katz as its outside legal advisor.
 
On May 17, 2006, the parties entered into a confidentiality agreement, and thereafter commenced mutual due diligence.
 
At about that time, the parties and their outside counsel also began preliminary drafting of the transaction documents. Discussions between representatives of Regions and AmSouth continued regarding a potential business combination and the benefits for each company that could result from such a transaction. As a result of these discussions, the parties agreed to recommend to their respective boards of directors an all-stock transaction in which AmSouth would merge into Regions, with Regions being the surviving corporation, and having a fixed exchange ratio of 0.7974 shares of Regions common stock for each share of AmSouth common stock, which was designed to produce an at-market exchange ratio based on the ratio of the closing market price of AmSouth common stock on May 22, 2006 to the closing market price of Regions common stock on May 22, 2006. The parties and their respective counsel also negotiated the other terms of the definitive transaction agreements and exchanged disclosure schedules.
 
On May 24, 2006, the board of directors of Regions met with senior management and their outside legal and financial advisors. Management reviewed for the Regions board of directors the background of discussions with AmSouth and the progress of negotiations, and reported on Regions’ due diligence investigations of AmSouth. Merrill Lynch reviewed with the Regions board of directors the structure and other terms of the proposed transaction, and financial information regarding AmSouth, Regions and the transaction, as well as information regarding peer companies and comparable transactions. In connection with the deliberation by the Regions board of directors, Merrill Lynch rendered to the Regions board of directors its oral opinion (subsequently confirmed in writing), as described under “— Opinion of Regions’ Financial Advisor”, that, as of the date of its opinion, and subject to and based on the qualifications, limitations and assumptions set forth in its written opinion, the exchange ratio in the merger was fair, from a financial point of view, to Regions.
 
Representatives of Wachtell, Lipton, Rosen & Katz discussed with the Regions board of directors the legal standards applicable to its decisions and actions with respect to its consideration of the proposed transaction, and reviewed the legal terms of the proposed transaction agreements. Representatives of Wachtell, Lipton, Rosen & Katz also discussed with the Regions board of directors the shareholder and regulatory approvals that would be required to complete the proposed merger, the likely process and timetable of the merger including obtaining the required shareholder and regulatory approvals and compensation and benefits issues in connection with the merger. Wachtell, Lipton, Rosen & Katz also reviewed for the Regions board of directors a set of draft resolutions relating to the proposed merger.
 
Following these discussions, and review and discussion among the members of the Regions board of directors, including consideration of the factors described under “— Regions’ Reasons for the Merger; Recommendation of the Merger by the Regions Board of Directors”, the Regions board of directors unanimously determined that the transactions contemplated by the merger agreement and the related transactions and agreements are advisable and in the best interests of Regions and its shareholders, and the directors voted unanimously to approve the merger with AmSouth, to approve and adopt the merger agreement and to approve the related transactions and agreements.

AmSouth’s board of directors met in the afternoon of May 24, 2006. Mr. Ritter and other senior AmSouth executives reviewed the status of discussions and negotiations with Regions since the previous board meeting. Members of AmSouth’s management discussed the due diligence process and findings and financial aspects of the transaction, including the proposed merger consideration, accretion/dilution analysis, post-merger capital ratios, dividend rates, estimated expense savings and revenue opportunities. Management also discussed strategic factors related to the proposed transaction. Representatives from Goldman Sachs delivered a financial analysis of the transaction and then advised the AmSouth board of directors of its opinion that, as of May 24, 2006, and based upon the assumptions made, procedures followed, matters considered and limitations on the review undertaken by Goldman Sachs, all as set forth in its written opinion, the exchange ratio pursuant to the merger agreement was fair, from a financial point of view, to holders of AmSouth common stock.
 
Representatives of Sullivan & Cromwell LLP advised the AmSouth board regarding certain legal matters related to the proposed transaction, including the fiduciary obligations of AmSouth’s directors in connection with their consideration of the proposed merger agreement. Representatives of Sullivan & Cromwell LLP also presented information about the proposed merger agreement, including key terms relating to structure, covenants, representations and warranties and closing conditions. Sullivan & Cromwell LLP representatives also discussed regulatory and stockholder approvals required to complete the merger and the terms of the option agreements. Following the presentations, directors addressed questions to members of AmSouth’s management, representatives of Sullivan & Cromwell LLP and representatives of Goldman Sachs.
 
Following these discussions, and review and discussion among the members of the AmSouth board of directors, including consideration of the factors described under “ — AmSouth’s Reasons for the Merger; Recommendation of the Merger by the AmSouth Board of Directors”, the AmSouth board of directors unanimously determined that the transactions contemplated by the merger agreement and the related transactions and agreements are advisable and in the best interests of AmSouth and its stockholders, and the directors voted unanimously to approve the merger with Regions, to approve and adopt the merger agreement and to approve the related transactions and agreements.
 
The transaction was announced on the morning of May 25, 2006 in a press release issued jointly by Regions and AmSouth.
 
Regions’ Reasons for the Merger; Recommendation of Regions’ Board of Directors
 
In reaching its decision to adopt the merger agreement and recommend adoption of the merger agreement to the Regions stockholders, the Regions board of directors consulted with Regions’ management, as well as with its outside legal and financial advisors, and considered a number of factors, including:
 
  •  its knowledge of Regions’ business, operations, financial condition, earnings and prospects and of AmSouth’s business, operations, financial condition, earnings and prospects, taking into account its familiarity with AmSouth and its management and the results of Regions’ due diligence review of AmSouth;
 
  •  its knowledge of the current environment in the financial services industry, including economic conditions and the interest rate environment, the continuing consolidation, increased operating costs resulting from regulatory initiatives and compliance mandates, increasing nationwide competition, and current financial market conditions and the likely effects of these factors on the companies’ potential growth, development, productivity and strategic options;
 
  •  its belief that the transaction will significantly strengthen Regions’ presence in its core markets, and provide broader access to demographically attractive markets such as Florida, while improving customer service as a result of an expanded branch and distribution network and increased and improved product offerings;
 
  •  the fact that the combined company would become one of the top 10 U.S. bank holding companies, based on currently estimated pro forma market capitalization, tangible common equity, deposits and number of branches, and its belief that the combined company’s increased size and scale and quality of operations would better position Regions to compete and grow its business;
 
  •  its belief that the combined company would be better poised to take advantage of a number of strategic opportunities, including by building upon AmSouth’s de novo branching efforts and expertise and further


21


Table of Contents

  developing Morgan Keegan’s leading regional brokerage platform in AmSouth markets and facilitating opportunities in complementary AmSouth businesses;
 
  •  the potential cost saving opportunities, and the related potential impact on the combined company’s earnings;
 
  •  its belief that the combined company will be positioned to benefit from increased credit portfolio diversity and increased lending capacity;
 
  •  the financial analyses and presentation of Merrill Lynch, and its opinion, dated May 24, 2006, to the effect that, as of that date and based upon and subject to the assumptions, qualifications and limitations set forth in its opinion, the exchange ratio pursuant to the merger agreement was fair, from a financial point of view, to Regions (see “— Opinion of Regions’ Financial Advisor”);
 
  •  the fact that the exchange ratio represented an at-market transaction based on the ratio of the closing market price of AmSouth common stock on May 22, 2006 to the closing market price of Regions common stock on May 22, 2006, and that the exchange ratio is fixed, which the Regions board believed presented a unique and attractive strategic opportunity and was consistent with market practice for mergers of this type and with the strategic purpose of the merger;
 
  •  the terms and conditions of the merger agreement, and the Regions board’s assessment of the likelihood that the merger would be completed in a timely manner and that the management team of the combined company would be able to successfully integrate and operate the businesses of the combined company after the merger;
 
  •  the governance arrangements with respect to the combined company post-merger, including the fact that Mr. Moore will serve as Chairman of the combined company, and the proposed composition of the board of directors and the committees of the board of directors;
 
  •  the experience of the Board of Directors with the recent merger of Regions and Union Planters, including shared governance arrangements and the experience of the Board in overseeing the integration of those two businesses;
 
  •  the regulatory and other approvals required in connection with the merger, the possibility that meaningful branch divestitures would be required in overlapping markets in connection with obtaining necessary regulatory approvals, and the likelihood regulatory approvals will be received in a timely manner and without unacceptable conditions;
 
  •  the potential risk of diverting management focus and resources from other strategic opportunities and from operational matters while working to implement the merger; and
 
  •  the risks of the type and nature described under “Cautionary Statement Regarding Forward-Looking Statements” and in the filings of each company incorporated in this document by reference.
 
In view of the wide variety of factors considered in connection with its evaluation of the merger and the complexity of these matters, the Regions board of directors did not find it useful and did not attempt to quantify or assign any relative or specific weights to the various factors that it considered in reaching its determination to approve the merger and the merger agreement and recommend that Regions stockholders vote “FOR” the adoption of the merger agreement. In addition, individual members of the Regions board of directors may have given differing weights to different factors. The Regions board of directors conducted an overall analysis of the factors described above, including through discussions with, and questioning of, Regions’ management and outside legal and financial advisors. The Regions board of directors also considered the advice of Merrill Lynch, its financial advisor, as well as Merrill Lynch’s analyses of the financial terms of the merger and relied on its opinion as to the fairness, from a financial point of view, of the exchange ratio in the merger to Regions.
 
It should be noted that this explanation of the Regions board’s reasoning and all other information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors discussed under the heading “Cautionary Statement Regarding Forward-Looking Statements.”

The Regions board of directors unanimously determined that the merger, the merger agreement and the transactions contemplated by the merger agreement are advisable and in the best interests of Regions and its stockholders and unanimously approved and adopted the merger agreement. The Regions board unanimously recommends that Regions stockholders vote “FOR” the adoption of the merger agreement.
 
AmSouth’s Reasons for the Merger; Recommendation of AmSouth’s Board of Directors
 
AmSouth’s board concluded, in reaching its decision to recommend the merger to AmSouth stockholders, that Regions and AmSouth have a unique strategic fit, that the merger provides an opportunity for enhanced financial performance and stockholder value and that the merger involves substantial participation by AmSouth’s board and management in the operations of the combined company. In concluding that the merger is in the best interests of AmSouth and its stockholders, AmSouth’s board considered, among other things, the following factors:
 
  •  The current environment in the financial services industry, including national and regional economic conditions, continued consolidation in the financial services industry, evolving trends in technology, regulatory compliance requirements, nationwide competition, and the likely effect of these factors on AmSouth on both a stand-alone basis and in the context of the proposed merger;
 
  •  AmSouth’s and Regions’ business, operations, financial condition, asset quality, earnings and prospects. In reviewing these factors, based on the information provided in due diligence, AmSouth’s board considered that Regions’ business and operations complement those of AmSouth, that Regions’ financial condition and asset quality are sound and should further strengthen the combined company’s balance sheet, and that Regions’ earnings and prospects, and the synergies potentially available in the proposed merger create the opportunity for the combined company having superior future earnings and prospects compared to AmSouth’s earnings and prospects on a stand-alone basis. In particular, AmSouth’s board considered the following:
 
  •  the opportunity to leverage complementary business lines across a larger customer base in diverse markets;
 
  •  the opportunity to strengthen the combined company’s presence in its core markets — Alabama, Florida, Tennessee, Louisiana and Mississippi; and
 
  •  the creation of a top-10 U.S. bank holding company, with $140 billion in assets and $95 billion in deposits.
 
  •  The structure of the transaction as a merger of equals in which AmSouth’s board and management would have substantial participation in the combined company. In particular, AmSouth’s board considered the following:
 
  •  The board of the directors of the combined company would consist of nine AmSouth directors and 12 Regions directors;
 
  •  The chief executive officer of the combined company would be AmSouth’s current chief executive officer; and
 
  •  The substantial participation of other AmSouth officers in senior management positions in the combined company.
 
  •  The consistency of the merger with AmSouth’s business strategies, including achieving strong earnings growth, improving customer attraction and retention and focusing on expense control. The board concluded after its analysis that AmSouth and Regions are a complementary fit because of the nature of the markets served and products offered by AmSouth and Regions and the expectation that the merger would provide economies of scale, expanded product offerings, expanded opportunities for cross-selling, cost savings opportunities, and enhanced opportunities for growth.
 
  •  AmSouth’s legal advisors’ expectation that the merger will qualify as a transaction of a type that is generally tax-free for United States federal income tax purposes to AmSouth, Regions, and AmSouth’s stockholders.

Table of Contents

 
  •  Regions’ and AmSouth’s shared belief in a deliberate, disciplined approach to the combination, structured to generate positive operating leverage through expense control and quality revenue growth, as well as the willingness to exit low return markets and businesses to focus on high density/higher growth markets.
 
  •  The synergies and revenue opportunities expected from the merger.
 
  •  The AmSouth board’s belief that the merger is likely to increase value to stockholders. In particular, AmSouth’s board believes that:
 
  •  The combined company is expected to generate meaningful excess capital that may be reinvested and deployed for the stockholders’ benefit;
 
  •  The merger is expected to be dilutive to AmSouth’s GAAP earning per share in 2007 before the synergies are fully realized and is expected to be accretive to GAAP earnings per share thereafter, and is expected to be accretive to cash earnings per share in 2007 and significantly accretive to cash earnings per share thereafter; and
 
  •  The dividend paid by the combined company will represent an approximately 7% increase in the dividend currently paid by AmSouth on its common stock.
 
  •  The diversification of credit risk in terms of both types of lending and in geographic coverage and the minimal overlapping credits.
 
  •  Goldman Sachs’s financial presentation to AmSouth’s board, including Goldman Sachs’s opinion, dated May 24, 2006, as to the fairness, from a financial point of view, to the holders of AmSouth common stock of the exchange ratio pursuant to the merger agreement, as discussed in “— Opinion of AmSouth’s Financial Advisor” below.
 
  •  The AmSouth board’s understanding that the 0.7974 exchange ratio was fixed and would not fluctuate, as is customary in transactions of this nature, and in view of the long-term strategic purposes of the merger.
 
  •  The AmSouth board’s understanding that the 0.7974 exchange ratio is higher than the average historical exchange ratio for the three-year period ended May 23, 2006, as well as other specified periods within that three-year period.
 
  •  The review by AmSouth’s board with its legal advisor, Sullivan & Cromwell LLP, of the provisions of the merger agreement and stock option agreements, including the provisions of the merger agreement and the option agreements designed to enhance the probability that the merger will be completed.
 
  •  The AmSouth board’s review and discussions with AmSouth’s management and outside advisors concerning the due diligence examination of the operations, financial condition, regulatory compliance and regulatory compliance programs and prospects of Regions.
 
  •  The AmSouth board’s expectation, after consulting with legal counsel, that the required regulatory approvals could be obtained, although recognizing that substantial divestitures would be required.
 
AmSouth’s board also considered the potential risks outlined below but concluded that the anticipated benefits of combining with Regions were likely to outweigh substantially these risks. The risks included:
 
  •  The possibility that the merger and the related integration process could result in the loss of key employees, in the disruption of AmSouth’s on-going business and in the loss of customers;
 
  •  The possibility of encountering difficulties in achieving cost savings and revenue synergies in the amounts currently estimated or in the time frame currently contemplated;
 
  •  The potential for an initial negative impact on the market price of AmSouth’s stock;
 
  •  The substantial merger-related restructuring charges;
 
  •  The impact of divestitures of branches, deposits and assets that regulatory authorities may require in connection with the merger, which may result in lost customer relationships and reduce the amount of income the combined company could have realized without such divestitures;


24


Table of Contents

 
  •  That the merger might not receive the necessary regulatory approvals and clearances to complete the merger or that governmental authorities could attempt to condition their approval of the merger on the companies’ compliance with burdensome conditions; and
 
  •  That Regions would receive an option to purchase up to 19.9% of AmSouth’s outstanding stock under certain conditions, as described under the heading “The Stock Option Agreements”.
 
Although each member of AmSouth’s board individually considered these and other factors, the board did not collectively assign any specific or relative weights to the factors considered and did not make any determination with respect to any individual factor. The board collectively made its determination based on the conclusion reached by its members, in light of the factors that each of them considered appropriate, that the merger is in the best interests of AmSouth and its stockholders.
 
AmSouth’s board of directors realized there can be no assurance about future results, including results expected or considered in the factors listed above, such as assumptions regarding anticipated cost savings and earnings accretion/dilution. However, the board concluded that the potential positive factors outweighed the potential risks of completing the merger.
 
It should be noted that this explanation of the AmSouth board’s reasoning and all other information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors discussed under the heading “Cautionary Statement Regarding Forward-Looking Statements.”
 
For the reasons set forth above, the AmSouth board of directors determined that the merger, the merger agreement and the transactions contemplated by the merger agreement are advisable and in the best interest of AmSouth and its stockholders, and unanimously approved and adopted the merger agreement. The AmSouth board of directors unanimously recommends that the AmSouth stockholders vote “FOR” the adoption of the merger agreement.
 
Opinions of Financial Advisors
 
Regions engaged Merrill Lynch as its financial advisor and AmSouth engaged Goldman Sachs as its financial advisor in connection with the merger based on their experience and expertise. Merrill Lynch and Goldman Sachs are internationally recognized investment banking firms that have substantial experience in transactions similar to the merger.
 
Opinion of Regions’ Financial Advisor
 
Regions’ board of directors engaged Merrill Lynch to act as its financial advisor in connection with the merger, and to render an opinion as to whether the exchange ratio pursuant to the merger agreement was fair from a financial point of view to Regions.
 
On May 24, 2006, Merrill Lynch delivered its oral opinion to Regions’ board of directors, subsequently confirmed in its written opinion as of that same date, that, as of that date, and based upon and subject to the assumptions made, matters considered and qualifications and limitations set forth in the written opinion, the exchange ratio pursuant to the merger agreement was fair from a financial point of view to Regions.
 
The full text of the written opinion of Merrill Lynch, dated May 24, 2006, which sets forth the assumptions made, matters considered and qualifications and limitations on the review undertaken by Merrill Lynch, is attached as Annex D to this document and is incorporated into this document by reference. The following summary of Merrill Lynch’s opinion is qualified in its entirety by reference to the full text of the opinion. Stockholders of Regions are urged to read and should read the entire opinion carefully. Merrill Lynch has consented to the inclusion in this document of its opinion dated May 24, 2006 and of the summary of that opinion set forth below.
 
In preparing its opinion to Regions’ board of directors, Merrill Lynch performed various financial and comparative analyses, including those described below. The summary set forth below does not purport to be a complete description of the analyses underlying Merrill Lynch’s opinion or the presentation made by Merrill Lynch to Regions’ board of directors. The preparation of a fairness opinion is a complex analytic process involving various determinations as to the most appropriate and relevant methods of financial analysis and the application of those


25


Table of Contents

methods to the particular circumstances and, therefore, a fairness opinion is not readily susceptible to partial analysis or summary description. In arriving at its opinion, Merrill Lynch did not attribute any particular weight to any analysis or factor considered by it, but rather made its determination as to fairness on the basis of its experience and professional judgment after considering the results of all of its analyses. Accordingly, Merrill Lynch believes that its analyses must be considered as a whole and that selecting portions of its analyses and factors, or focusing on information presented in tabular format, without considering all of the analyses and factors or the narrative description of the analyses, would create a misleading or incomplete view of the process underlying its opinion.
 
In arriving at its opinion, Merrill Lynch, among other things:
 
  •  reviewed certain publicly available business and financial information relating to AmSouth and Regions that Merrill Lynch deemed to be relevant;
 
  •  reviewed certain information, including financial forecasts, relating to the business, earnings, cash flow, assets, liabilities and prospects of AmSouth and Regions, as well as the amount and timing of the cost savings and related expenses and synergies expected to result from the merger, which are herein referred to as the expected synergies, furnished to Merrill Lynch by AmSouth and Regions;
 
  •  conducted discussions with members of senior management and representatives of AmSouth and Regions concerning the matters described in the preceding two bullet points, as well as their respective businesses and prospects before and after giving effect to the merger and the expected synergies;
 
  •  reviewed the market prices and valuation multiples for AmSouth’s common stock and Regions’ common stock and compared them with those of certain publicly traded companies that Merrill Lynch deemed to be relevant;
 
  •  reviewed the results of operations of AmSouth and Regions and compared them with those of certain publicly traded companies that Merrill Lynch deemed to be relevant;
 
  •  compared the proposed financial terms of the merger with the financial terms of certain other transactions that Merrill Lynch deemed to be relevant;
 
  •  participated in certain discussions among representatives of AmSouth and Regions and their financial and legal advisors;
 
  •  reviewed the potential pro forma impact of the merger;
 
  •  reviewed a draft dated May 23, 2006 of the merger agreement;
 
  •  reviewed a draft dated May 23, 2006 of the stock option agreements between Regions and AmSouth; and
 
  •  reviewed such other financial studies and analyses and took into account such other matters as Merrill Lynch deemed necessary, including its assessment of general economic, market and monetary conditions.
 
In preparing its opinion, Merrill Lynch assumed and relied on the accuracy and completeness of all information supplied or otherwise made available to it, discussed with or reviewed by or for it, or that was publicly available. Merrill Lynch did not assume any responsibility for independently verifying such information and did not undertake any independent evaluation or appraisal of any of the assets or liabilities of AmSouth or Regions and it was not furnished with any such evaluation or appraisal, nor did it evaluate the solvency or fair value of AmSouth or Regions under any state or federal laws relating to bankruptcy, insolvency or similar matters. In addition, Merrill Lynch did not assume any obligation to conduct any physical inspection of the properties or facilities of AmSouth or Regions. With respect to the financial forecast information and the expected synergies furnished to or discussed with Merrill Lynch by AmSouth or Regions, Merrill Lynch assumed that they had been reasonably prepared and reflected the best currently available estimates and judgment of the management of AmSouth or Regions as to the expected future financial performance of AmSouth or Regions, as the case may be, and the expected synergies. Merrill Lynch further assumed that the merger would qualify as a tax-free reorganization for U.S. federal income tax purposes. Merrill Lynch also assumed that the final form of the merger agreement and each stock option agreement would be substantially similar to the last draft reviewed by it.

Merrill Lynch’s opinion is necessarily based upon market, economic and other conditions as they existed and could be evaluated on, and on the information made available to Merrill Lynch as of, May 24, 2006. Merrill Lynch further assumed that in the course of obtaining the necessary regulatory or other consents or approvals (contractual or otherwise) for the merger, no restrictions, including any divestiture requirements or amendments or modifications, would be imposed that will have a material adverse effect on the contemplated benefits of the merger.
 
In connection with the preparation of its opinion, Merrill Lynch was not authorized by Regions or the board of directors of Regions to solicit, nor did Merrill Lynch solicit, third party indications of interest for the acquisition of all or any part of Regions.
 
Merrill Lynch’s opinion is addressed to Regions’ board of directors and addresses only the fairness, from a financial point of view, of the exchange ratio pursuant to the merger agreement. The opinion does not address the merits of the underlying decision of Regions to engage in the merger and does not constitute, nor should it be construed as, a recommendation to any stockholder of Regions as to how that stockholder should vote with respect to the merger or any matter related thereto. In addition, the opinion of Merrill Lynch does not address and Merrill Lynch was not asked to address, the fairness to, or any other consideration of, the holders of any class of securities, creditors or other constituencies of Regions. Merrill Lynch did not express any opinion as to the prices at which the common stock of Regions will trade following the announcement or consummation of the merger.
 
Merrill Lynch’s Financial Analysis
 
The following is a summary of the material financial analyses that Merrill Lynch performed in connection with its opinion to Regions’ board of directors dated May 24, 2006. The financial analyses summarized below include information presented in tabular format. In order to understand fully the financial analyses performed by Merrill Lynch, the tables must be read together with the accompanying text of each summary. The tables alone do not constitute a complete description of the financial analyses, and if viewed in isolation could create a misleading or incomplete view of the financial analyses performed by Merrill Lynch. To the extent the following quantitative information reflects market data, except as otherwise indicated, Merrill Lynch based this information on market data as they existed prior to May 24, 2006. This information, therefore, does not necessarily reflect current or future market conditions.
 
Calculation of Transaction Value
 
Merrill Lynch reviewed the terms of the merger. The merger consideration had an implied total offer value of $28.53 per share of AmSouth common stock based upon the closing price of Regions common stock of $35.78 on May 22, 2006. Merrill Lynch noted that AmSouth stockholders will receive 0.7974 shares of Regions common stock for each share of AmSouth common stock. Merrill Lynch also noted that the combination of Regions and AmSouth would have an implied aggregate total value of approximately $26 billion as of May 22, 2006.
 
Historical Market-for-Market Exchange Ratio Analysis
 
Merrill Lynch also analyzed the historical exchange ratio that existed between AmSouth common stock and Regions common stock for selected periods during the past year to illustrate the implied exchange ratio between the companies’ common stock at such intervals. The results of Merrill Lynch’s analysis are set forth in the following table:

No company used in the comparable company analyses described above is identical to AmSouth, Regions, or the pro forma combined company, as the case may be. Accordingly, an analysis of the results of the foregoing necessarily involves complex considerations and judgments concerning financial and operating characteristics and other factors that could affect the merger, public trading or other values of the companies to which they are being compared. Mathematical analyses, such as determining the mean or median, are not of themselves meaningful methods of using comparable company data.

Discounted Dividend Analysis — AmSouth
 
Merrill Lynch performed a discounted dividend analysis to estimate a range of present values per share of AmSouth common stock. The valuation range was determined by adding (i) the present value of AmSouth’s earnings available for dividends, net of earnings necessary to maintain AmSouth’s tangible common equity to tangible assets ratio at 6.5% through December 31, 2011, and (ii) the present value of the “terminal value” of AmSouth common stock. In calculating the terminal value of AmSouth common stock, Merrill Lynch applied multiples ranging from 11.5x to 13.5x to year 2012 forecasted cash earnings. The dividend stream and terminal value were then discounted back to May 22, 2006 using discount rates ranging from 11.0% to 13.0%, which are rates Merrill Lynch viewed as the appropriate range for a company with AmSouth’s risk characteristics.
 
In performing this analysis, Merrill Lynch used the First Call consensus earnings per share estimate for AmSouth for 2007. After 2007, earnings per share were assumed to increase annually at 7.5%, the First Call consensus projected earnings growth rate for AmSouth. The analysis assumed annual asset growth rate of 5% for AmSouth.
 
Based on the foregoing criteria and assumptions, Merrill Lynch determined that the stand-alone present value of the AmSouth common stock ranged from $25.29 to $31.20 per share.
 
Discounted Dividend Analysis — Regions
 
Merrill Lynch performed a discounted dividend analysis to estimate a range of present values per share of Regions common stock. The valuation range was determined by adding (i) the present value of Regions’ earnings available for dividends, net of earnings necessary to maintain Regions’ tangible common equity to tangible assets ratio at 6.5% through December 31, 2011, and (ii) the present value of the “terminal value” of Regions common stock. In calculating the terminal value of Regions common stock, Merrill Lynch applied multiples ranging from 11.5x to 13.5x to year 2012 forecasted cash earnings. The dividend stream and terminal value were then discounted back to May 22, 2006 using discount rates ranging from 11.0% to 13.0%, which are rates Merrill Lynch viewed as the appropriate range for a company with Regions’ risk characteristics.
 
In performing this analysis, Merrill Lynch used the First Call consensus earnings per share estimate for Regions for 2007. After 2007, earnings per share were assumed to increase annually at 8%, the First Call consensus projected earnings growth rate for Regions. The analysis assumed an annual asset growth rate of 5% for Regions.
 
Based on the foregoing criteria and assumptions, Merrill Lynch determined that the stand-alone present value of the Regions common stock ranged from $31.77 to $39.08 per share.
 
Discounted Dividend Analysis — Pro Forma Combined Company
 
Merrill Lynch performed a pro forma discounted dividend analysis to estimate a range of present values per share of Regions common stock to reflect the impact of the merger with AmSouth. The valuation range was determined by adding (i) the present value of the pro forma combined company’s earnings available for dividends, net of earnings necessary to maintain the pro forma combined company’s tangible common equity to tangible assets ratio at 6.11% through December 31, 2011, and (ii) the present value of the “terminal value” of the pro forma combined company’s common stock. In calculating the terminal value of the pro forma combined company’s common stock, Merrill Lynch applied multiples ranging from 11.5x to 13.5x to year 2012 forecasted cash earnings. The dividend stream and terminal value were then discounted back to May 22, 2006 using discount rates ranging from 11.0% to 13.0%, which are rates Merrill Lynch viewed as the appropriate range for a company with Regions’ risk characteristics on a pro forma basis.
 
In performing this analysis, Merrill Lynch used the First Call consensus earnings per share estimate for AmSouth and Regions for 2007. After 2007, earnings per share were assumed to increase annually at 8% for Regions and 7.5% for AmSouth, their respective First Call consensus projected earnings growth rates. This analysis also assumed $420 million in pre-tax synergies, of which approximately 36% are projected to be realized in 2007, 83% in 2008, and 100% in 2009, and a $700 million pre-tax restructuring charge. The analysis assumed an annual asset growth rate of 5% for the pro forma combined company.

Table of Contents

Based on the foregoing criteria and assumptions, Merrill Lynch determined that the present value of the Regions common stock, pro forma for the merger, ranged from $35.88 to $44.14 per share.
 
Contribution Analysis
 
Merrill Lynch also reviewed the relative contributions of Regions and AmSouth to the pro forma combined company with respect to certain financial and operating measurements. This analysis was based on market information as of May 22, 2006 and financial data as of, or for the quarter ended, March 31, 2006. Merrill Lynch then compared these contributions to the pro forma implied stock ownership interests of Regions and AmSouth of 62% and 38%, respectively, resulting from the merger. These pro forma implied stock ownership percentages were based on the exchange ratio and on fully diluted shares based on stated shares outstanding and options and warrants accounted for under the treasury stock method based on the market price as of May 22, 2006.
 
The following table indicates what Regions’ and AmSouth’s percentage contributions would have been on a pro forma basis to the combined company in the categories listed. The fully diluted market capitalization analysis was based on fully diluted shares based on stated shares outstanding and options and warrants accounted for under the treasury stock method based on the market price as of May 22, 2006. The 2007 estimated net income analyses were based on consensus First Call earnings estimates.

Comparable Transactions Analysis
 
Merrill Lynch reviewed eight merger transactions since April 1998 involving companies in the commercial banking industry. Unless otherwise indicated in the table below, Merrill Lynch calculated the premium of the exchange ratio in the selected transactions to the ratio of the stock price for the parties in the selected transaction on the day prior to the announcement of the transaction, and calculated the resulting ownership percentages of the constituent shareholders in the combined company. Merrill Lynch also reviewed the selected transactions to determine (1) the relative contributions of each merger partner to the total assets, tangible equity, market value and earnings of the combined company and (2) the composition of the board of directors of the combined company. The results of this analysis are as follows:

Pro Forma Financial Impact
 
Based on the offer price of 0.7974 shares of Regions common stock for each share of AmSouth common stock, Merrill Lynch analyzed the pro forma per share financial impact of the merger on Regions’ cash earnings per share and GAAP earnings per share. This analysis was based on the First Call consensus earnings per share estimates for AmSouth and Regions for 2007. After 2007, earnings per share were assumed to increase annually at 8% for Regions and 7.5% for AmSouth, their respective First Call consensus projected earnings growth rates. The analysis assumed pre-tax cost synergies of $420 million, of which approximately 36% were projected to be realized in 2007, 83% in 2008 and 100% in 2009. In analyzing the pro forma financial impact of the merger, Merrill Lynch also assumed that there would be a pre-tax restructuring charge of $700 million, of which $350 million would be taken in 2006, $175 million in 2007 and $175 million in 2008. The analysis further assumed (1) incremental share repurchases in order to maintain a projected pro forma common equity ratio of 6.11%, and (2) that a deposit premium of 12% will be received for approximately $2.5 billion in assumed deposit divestitures, with a 1.25% return on assets. The following table sets forth Merrill Lynch’s analyses.

General
 
In conducting its analyses and arriving at its opinions, Merrill Lynch utilized a variety of generally accepted valuation methods. The analyses were prepared for the purpose of enabling Merrill Lynch to provide its opinion to the Regions board of directors as to the fairness, from a financial point view, to Regions of the exchange ratio pursuant to the merger agreement and do not purport to be appraisals or necessarily to reflect the prices at which businesses or securities actually may be sold, which are inherently subject to uncertainty. In connection with its analyses, Merrill Lynch made, and was provided by the management of AmSouth and Regions management with, numerous assumptions with respect to industry performance, general business and economic conditions and other matters, many of which are beyond the control of Merrill Lynch, Regions or AmSouth. Analyses based on estimates or forecasts of future results are not necessarily indicative of actual past or future values or results, which may be significantly more or less favorable than suggested by such analyses. Because such analyses are inherently subject to uncertainty, being based upon numerous factors or events beyond the control of AmSouth, Regions or their respective advisors, neither Regions nor Merrill Lynch nor any other person assumes responsibility if future results or actual values are materially different from these forecasts or assumptions.
 
The terms of the merger were determined through negotiations between AmSouth and Regions and were approved by the board of directors of Regions. Although Merrill Lynch provided advice to Regions during the course of these negotiations, the decision to enter into the merger was solely that of Regions’ board of directors. The opinion and presentation of Merrill Lynch to Regions’ board of directors was only one of a number of factors taken into consideration by Regions’ board of directors in making its determination to approve and adopt the merger agreement and the transactions contemplated by the merger agreement, including the merger. Merrill Lynch’s opinion should not be viewed as determinative of the views of the board of directors of Regions or management with respect to the merger or the exchange ratio. Merrill Lynch’s opinion was provided to Regions’ board of directors to assist it in connection with its consideration of the merger and does not constitute a recommendation to any stockholder as to how to vote or take any other action with respect to the merger.
 
Regions retained Merrill Lynch based upon Merrill Lynch’s experience and expertise. Merrill Lynch is an internationally recognized investment banking and advisory firm. Merrill Lynch, as part of its investment banking business, is regularly engaged in the valuation of businesses and securities in connection with mergers and


31


Table of Contents

acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and valuations for corporate and other purposes.
 
Merrill Lynch is acting as financial advisor to Regions in connection with the merger and will receive a fee for its services, a significant portion of which is contingent upon the consummation of the merger. In addition Regions has agreed to reimburse Merrill Lynch for certain expenses incurred in connection with the services provided by Merrill Lynch and to indemnify Merrill Lynch and certain related persons and entities for certain liabilities, including liabilities under the U.S. federal securities laws, related to or arising out of its engagement.
 
Merrill Lynch has in the past provided financial advisory and financing services to Regions and AmSouth and may continue to do so. Merrill Lynch has received, and may receive, fees for the rendering of such services. In addition, in the ordinary course of its business, Merrill Lynch may actively trade the common stock and other securities of AmSouth as well as the common stock of Regions and other securities of Regions, for its own account and for the accounts of its customers and, accordingly, may at any time hold a long or short position in such securities.
 
Opinion of AmSouth’s Financial Advisor
 
Goldman Sachs was retained to act as financial advisor to AmSouth in connection with the merger. At a meeting of AmSouth’s board of directors held on May 24, 2006, Goldman Sachs rendered its opinion to the effect that, based upon and subject to the considerations set forth in the opinion and based upon such other matters as Goldman Sachs considered relevant, as of May 24, 2006, the exchange ratio pursuant to the merger agreement was fair from a financial point of view to the holders of AmSouth common stock.
 
The full text of the written opinion of Goldman Sachs, dated May 24, 2006, which sets forth the procedures followed, assumptions made, matters considered and limitations on the review undertaken in connection with the opinion, is attached as Annex E to this document and is incorporated herein by reference. AmSouth’s stockholders should read the opinion in its entirety. Goldman Sachs provided its opinion for the information and assistance of AmSouth’s board of directors in connection with its consideration of the merger. The Goldman Sachs opinion is not a recommendation as to how any holder of AmSouth’s common stock should vote with respect to the merger.
 
In connection with rendering its opinion and performing its related financial analyses, Goldman Sachs reviewed, among other things:
 
  •  the merger agreement;
 
  •  annual reports to stockholders and Annual Reports on Form 10-K of AmSouth and Regions for the five fiscal years ended December 31, 2005;
 
  •  certain interim reports to stockholders and Quarterly Reports on Form 10-Q of AmSouth and Regions;
 
  •  certain other communications from AmSouth and Regions to their respective stockholders;
 
  •  certain research analyst estimates for AmSouth and Regions; and
 
  •  certain internal financial analyses and forecasts for AmSouth and Regions prepared by their respective managements, including certain cost savings and the impact of certain divestitures projected by the managements of AmSouth and Regions to result from the merger.
 
Goldman Sachs also held discussions with members of the senior managements of AmSouth and Regions regarding their assessment of the strategic rationale for, and the potential benefits of, the merger and the past and current business operations, financial condition and future prospects of their respective companies. In addition, Goldman Sachs:
 
  •  reviewed the reported price and trading activity for shares of AmSouth common stock and Regions common stock;


32


Table of Contents

 
  •  compared certain financial and stock market information for AmSouth and Regions with similar information for certain other companies the securities of which are publicly traded;
 
  •  reviewed the financial terms of certain recent business combinations in the banking industry specifically and in other industries generally; and
 
  •  performed such other studies and analyses, and considered such other factors, as Goldman Sachs considered appropriate.
 
Goldman Sachs relied upon the accuracy and completeness of all of the financial, accounting, legal, tax and other information discussed with or reviewed by it and assumed such accuracy and completeness for purposes of rendering its opinion. In that regard, Goldman Sachs assumed with AmSouth’s consent that the financial forecasts for AmSouth and Regions, including the cost savings and the impact of certain divestitures projected by the managements of AmSouth and Regions to result from the merger, were reasonably prepared on a basis reflecting the best currently available estimates and judgments of AmSouth and Regions.
 
Goldman Sachs assumed that all governmental, regulatory or other consents and approvals necessary to complete the merger will be obtained without any adverse effect on AmSouth or Regions or on the expected benefits of the merger in any way meaningful to its analysis. Goldman Sachs is not an expert in the evaluation of loan and lease portfolios for purposes of assessing the adequacy of the allowance for losses with respect thereto and, accordingly, it assumed that such allowances for losses for AmSouth and Regions are in the aggregate adequate to cover such losses. In addition, Goldman Sachs did not review individual credit files nor did it make an independent evaluation or appraisal of the assets and liabilities (including any contingent, derivative or off-balance-sheet assets and liabilities) of AmSouth, Regions or any of their respective subsidiaries, and it was not furnished with any such evaluation or appraisal.
 
Goldman Sachs’ opinion does not address the underlying business decision of AmSouth to engage in the merger, nor did Goldman Sachs express any opinion as to the prices at which shares of Regions common stock will trade at any time.
 
Set forth below is a summary of the material financial analyses performed by Goldman Sachs in connection with rendering its opinion. The summary of the analyses of Goldman Sachs set forth below is not a complete description of the analyses underlying its opinion, and the order in which these analyses are described below is not indicative of any relative weight or importance given to those analyses by Goldman Sachs. The following summaries of financial analyses include information presented in tabular format. You should read these tables together with the full text of the summary financial analyses, as the tables alone are not a complete description of the analyses.
 
Unless otherwise indicated, the following quantitative information, to the extent it is based on market data, is based on market data as of May 23, 2006, the last trading day prior to the date on which Goldman Sachs made its presentation to AmSouth’s board of directors, and is not necessarily indicative of market conditions after such date. Earnings per share estimates used in the analyses described below were provided by Institutional Brokerage Estimate System, or IBES (a data service that compiles earnings estimates issued by securities analysts), and First Call Corporation, or First Call, an industry service provider of earnings estimates based on an average of earnings estimates published by securities analysts. Goldman Sachs’ analyses include the use of earnings on both a “GAAP” and “cash” basis. “GAAP earnings” are computed in accordance with generally accepted accounting principles. “Cash earnings” add back the after-tax amortization of any intangibles.
 
Historical Exchange Ratio Analysis.  Goldman Sachs calculated and reviewed the historical exchange ratios implied by dividing the daily closing price per share of AmSouth common stock by the daily closing price per share of Regions common stock for each trading day in the three-year period ended May 23, 2006, as well as the average of these exchange ratios for this three-year period and for other specified periods within the three-year period.

Large-Cap Bank Holding Companies
 
• SunTrust Banks, Inc.
  • Bank of America Corporation
• National City Corporation
  • Wells Fargo & Company

Goldman Sachs calculated and compared selected multiples and ratios for AmSouth, Regions and the selected companies based upon publicly available information. For companies that have recently made acquisitions, the calculations were made based upon publicly available pro forma data reflecting those acquisitions. Goldman Sachs used balance sheet and income statement information at or for the twelve months ended March 31, 2006. For the financial statistics set forth below, Goldman Sachs relied on information published by SNL DataSource, a recognized data service that collects, standardizes and disseminates relevant corporate, financial, market and mergers and acquisitions data for companies in the industries it covers, and FactSet, a data service that monitors and publishes compilations of earnings estimates by research analysts and other financial information. The selected multiples, statistics and ratios that were calculated and compared by Goldman Sachs were as follows:
 
  •  Closing share price as a percentage of 52-week high share price;
 
  •  Closing share price as a multiple of IBES EPS estimate for the next twelve months;
 
  •  Closing share price as a multiple of 2005 and estimated 2006 and 2007 GAAP EPS;
 
  •  Closing share price as a multiple of 2005 and estimated 2006 and 2007 cash EPS;

Discounted Cash Flow Analysis.  Goldman Sachs performed a discounted cash flow analysis to determine a range of estimated present values per share of AmSouth common stock and Regions common stock assuming each company continued to operate as a stand-alone company. This range was determined in each case by adding, respectively, (1) the “present value” of the estimated future excess capital of AmSouth and Regions and (2) the “present value” of the estimated “terminal value” of AmSouth common stock and Regions common stock as of March 31, 2011. “Terminal value” refers to the value of a particular asset at a specific future time. “Present value” refers to the current value of future cash flows obtained by discounting such future cash flows by an interest rate that takes into account risk, the opportunity cost of capital, expected returns and other appropriate factors.
 
Goldman Sachs estimated alternative reference ranges of per share values for AmSouth on a stand-alone basis as of March 31, 2011 using:
 
  •  median earnings estimates with respect to AmSouth for 2006 and 2007, as reported by First Call, the median First Call long-term EPS growth rate for AmSouth of 7.5% for 2008 through March 31, 2011, discount rates ranging from 8.0% to 12.0%, and a range of terminal P/E multiples of 11.0x to 15.0x; and
 
  •  median earnings estimates with respect to AmSouth for 2006 and 2007, as reported by First Call, GAAP EPS growth rates ranging from 5.5% to 9.5% for 2008 through March 31, 2011, a discount rate of 10.0%, and a range of terminal P/E multiples of 11.0x to 15.0x.
 
Goldman Sachs estimated alternative reference ranges of per share values for Regions on a stand-alone basis as of March 31, 2011 using:
 
  •  median earnings estimates with respect to Regions for 2006 and 2007, as reported by First Call, the median First Call long-term EPS growth rate for Regions of 8.0% for 2008 through March 31, 2011, discount rates ranging from 8.0% to 12.0%, and a range of terminal P/E multiples of 11.0x to 15.0x; and
 
  •  median earnings estimates with respect to Regions for 2006 and 2007, as reported by First Call, GAAP EPS growth rates ranging from 6.0% to 10.0% for 2008 through March 31, 2011, a discount rate of 10.0%, and a range of terminal P/E multiples ranging from 11.0x to 15.0x.

Contribution Analysis.  Goldman Sachs computed the relative contributions of AmSouth and Regions to (1) the assets, loans, deposits, common equity and tangible common equity of the combined company as at March 31, 2006, (2) actual 2005 and first quarter 2006 and estimated 2006, 2007 and 2008 net income of the combined company on both a “GAAP” basis and a “cash” basis, (3) the net interest income and operating non-interest income and expense of the combined company for the 12 months ending March 31, 2006, and (4) the fully-diluted market capitalization of the combined company as of May 23, 2006. Goldman Sachs used estimates provided by First Call for AmSouth and Regions GAAP and cash net income estimates for 2006 and 2007, and applied the median IBES long-term growth rate to the 2007 estimates to calculate GAAP and cash net income estimates for 2008.

Accretion/Dilution Analysis.  Goldman Sachs performed pro forma analyses of the financial impact of the merger on AmSouth’s and Regions’ (1) estimated earnings per share on both a “GAAP” and “cash” basis for 2007 and 2008 (assuming that cost savings are partially phased-in) and 2008 (assuming that cost savings are fully phased-in), (2) estimated closing book value per share and (3) pro forma annual dividend. The following assumptions were applied:
 
  •  Transaction closes on December 31, 2006;
 
  •  Financial data as of March 31, 2006;
 
  •  38% marginal corporate tax rate on transaction and earnings adjustments (excluding restructuring charges);
 
  •  GAAP earnings based on First Call EPS estimates for 2006 and 2007; 2008 estimates apply the First Call long-term growth rate to 2007 earnings; AmSouth and Regions First Call long-term growth rates equal to 7.5% and 8.0%, respectively;
 
  •  Cash earnings are equal to GAAP earnings, plus tax effected intangible asset amortization expense;
 
  •  Regions and AmSouth asset growth of 5.1% and 8.0%, respectively, until closing; pro forma tangible asset growth of 5.0% thereafter;
 
  •  AmSouth deposit growth of 5.0% until transaction close;
 
  •  Excess of purchase price over AmSouth’s tangible book value is allocated first to identifiable intangibles — 3.0% of core deposits (equal to total deposits less time deposits greater than $100,000 and foreign deposits), amortized using sum-of-years digits over 10 years, tax deductible for book purposes; transaction goodwill is the remaining portion of the premium to tangible book value, plus the goodwill associated with the deferred tax liability related to the identifiable intangible, not amortized;
 
  •  Pro forma analysis does not include purchase accounting adjustments other than core deposit intangibles;
 
  •  AmSouth options are converted into Regions options on the basis of the exchange ratio;
 
  •  Restructuring charge of $700 million: $350 million at closing; $175 million in 2007; $175 million in 2008; assumes a 5.50% pre-tax opportunity cost of cash and a 30% marginal corporate tax rate on restructuring charges;
 
  •  Pre-tax run rate of annual cost savings of $400 million: $150 million in 2007; $350 million in 2008;
 
  •  AmSouth annual expense growth of 5.0%;
 
  •  No revenue synergies included;
 
  •  $2.5 billion in deposits are divested at a 12.0% premium (earnings adjustments based on 1.25% after-tax return on average assets, a 53% efficiency ratio and a 35% fee income ratio);
 
  •  Proceeds of divestitures and excess capital utilized to fund share repurchases to target the pro forma transaction ratio of tangible common equity to tangible assets;
 
  •  Regions’ and AmSouth’s balance sheets are rolled forward to the transaction date; and
 
  •  Dividends per share increase $0.04 per year ($0.01 per quarter).

Pro Forma Shareholder Value Analysis.  Goldman Sachs performed a discounted cash flow analysis to determine an estimated present value per share of the common stock and estimated total market capitalization of the combined company. This value was determined by adding, respectively, (1) the “present value” of the estimated future excess capital of AmSouth and Regions on a pro forma basis and (2) the “present value” of the estimated “terminal value” of AmSouth’s and Regions’ common stock on a pro forma basis as of December 31, 2011.
 
Goldman Sachs estimated the “present values” of AmSouth’s and Regions’ common stock using median earnings estimates with respect to AmSouth and Regions for 2007, as reported by First Call, median First Call long-term EPS growth rates of 7.5% and 8.0%, respectively, and a discount rate of 10%. In estimating the pro forma excess capital of the combined company, Goldman Sachs took into account certain transaction adjustments, including cost savings, the opportunity cost of restructuring charges, the opportunity cost of increased dividends, the impact of deposit divestitures and intangible amortization (as more fully described above under the caption “Accretion/Dilution Analysis”).
 
As a result of this analysis, Goldman Sachs calculated an implied present value per share of the common stock of the combined company of $41.47 and an implied present value of total pro forma market capitalization of approximately $30.873 billion, which was accretive to the combined market capitalizations of AmSouth and Regions on a stand-alone basis, as set forth below ($ in millions):

(1) AmSouth market capitalization calculated by reference to the exchange ratio for the merger and Regions’ closing market price on May 23, 2006.
 
Precedent Transactions Analysis.  Goldman Sachs analyzed publicly available information for eleven selected comparable “merger-of-equal” transactions in the commercial banking industry, consisting of:
 
  •  Travelers Group Inc./Citicorp
 
  •  NationsBank Corporation/BankAmerica Corporation
 
  •  Norwest Corporation/Wells Fargo & Company

The preparation of a fairness opinion is a complex process involving various determinations as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances and, therefore, a fairness opinion is not readily susceptible to partial analysis or summary description. In arriving at its opinion, Goldman Sachs considered the results of all of the analyses and factors and did not isolate specific analyses or factors and reach separate conclusions as to whether or not any particular analysis or factor supported its opinion; rather, Goldman Sachs made its determination as to fairness on the basis of its experience and professional judgment after considering the results of all the underlying analyses and factors. Accordingly, Goldman Sachs believes that its analyses must be considered as a whole and that selecting portions of its analyses or certain factors, without considering all analyses and factors as a whole, could create a misleading or incomplete view of the processes underlying its opinion.

In its analyses, Goldman Sachs made numerous assumptions with respect to industry performance, general business, economic, market and financial conditions and various other matters, many of which are beyond the control of the parties and their advisors. Furthermore, no company or transaction used in Goldman Sachs’ analysis is identical to AmSouth, Regions or the proposed merger. Rather, the analyses of comparable companies and transactions involve complex considerations and judgments concerning differences in financial and operating characteristics of the companies and other factors that could affect the acquisition, public trading or other values of the companies or transactions being compared.
 
Goldman Sachs prepared its analyses for purposes of providing its opinion to AmSouth’s board of directors as to the fairness from a financial point of view to holders of shares of AmSouth common stock of the exchange ratio and to assist AmSouth’s board of directors in analyzing the proposed merger. The analyses do not purport to be appraisals or necessarily reflect the prices at which businesses or securities actually may be sold. Analyses based upon forecasts of future results are not necessarily indicative of actual future results, which may be significantly more or less favorable than those suggested by these analyses. Because these analyses are inherently subject to uncertainty, being based upon numerous factors or events beyond the control of the parties and their respective advisors, none of AmSouth, Regions, Goldman Sachs or any other person assumes responsibility if future results are materially different from those forecasted.
 
Goldman Sachs’ opinion was one of many factors considered by the AmSouth board of directors in its evaluation of the merger and should not be viewed as determinative of the views of the board of directors of AmSouth or management with respect to the merger or the exchange ratio.
 
Goldman Sachs and its affiliates, as part of their investment banking business, are continually engaged in performing financial analyses with respect to businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and other transactions as well as for estate, corporate and other purposes. Goldman Sachs acted as financial advisor to AmSouth in connection with, and participated in certain of the negotiations leading to, the merger. In addition, Goldman Sachs has provided certain investment banking services to AmSouth from time to time, including having acted as:

Goldman Sachs may also provide investment banking services to Regions in the future. In connection with the above-described investment banking services, Goldman Sachs has received, and may receive, compensation.
 
Goldman Sachs is a full service securities firm engaged, either directly or through its affiliates, in securities trading, investment management, financial planning and benefits counseling, risk management, hedging, financing and brokerage activities for both companies and individuals. In the ordinary course of these activities, Goldman Sachs and its affiliates may provide such services to AmSouth, Regions and their respective affiliates, may actively trade the debt and equity securities (or related derivative securities) of AmSouth and Regions for their own account and for the accounts of their customers and may at any time hold long and short positions of such securities.
 
AmSouth selected Goldman Sachs as its financial advisor because it is an internationally recognized investment banking firm that has substantial experience in transactions similar to the merger. Pursuant to a letter agreement dated May 24, 2006, AmSouth engaged Goldman Sachs as financial advisor in connection with the contemplated transaction. Pursuant to the terms of the engagement letter, AmSouth has agreed to pay Goldman Sachs a transaction fee upon completion of the merger. AmSouth has also agreed to reimburse Goldman Sachs for all reasonable out-of-pocket expenses, including fees of counsel, and to indemnify Goldman Sachs and certain related persons against specified liabilities, including liabilities under the federal securities laws, relating to or arising out of its engagement.

Board of Directors and Management of Regions Following the Merger
 
Composition of the Board of Directors
 
Upon completion of the merger, the board of directors of Regions will consist of twelve current directors of Regions designated by Regions (plus up to one additional director to be added prior to the completion of the merger with the mutual agreement of Regions and AmSouth), and nine current directors of AmSouth designated by AmSouth (plus up to one additional director to be added prior to the completion of the merger with the mutual agreement of Regions and AmSouth). The former Regions directors and former AmSouth directors will be apportioned among the three classes of the Regions board of directors as equally as possible.
 
Until the third anniversary of the completion of the merger, if there is a vacancy created by the cessation of service of a Regions designee, a majority of the remaining Regions designees will propose a nominee to the nominating and corporate governance committee of the Regions board of directors to fill the vacant position, and if there is a vacancy created by the cessation of service of an AmSouth designee, a majority of the remaining AmSouth designees will propose a nominee to the nominating and corporate governance committee of the Regions board of directors to fill the vacant position.
 
Committees of the Board of Directors
 
Until the third anniversary of the completion of the merger, the chairmanships of the following committees of the board of directors of Regions will be divided evenly between individuals who are former Regions directors and those who are former AmSouth directors: the audit committee, the nominating and corporate governance committee, the compensation committee and the risk management committee. Also until the third anniversary of the completion of the merger, the total membership on the nominating and governance committee will include an equal number of former Regions directors and former AmSouth directors. In addition, it is the intention of Regions and AmSouth that until the third anniversary of the completion of the merger, subject to any relevant independence and expertise requirements under applicable law or stock exchange rule, the membership of each of the audit committee, the nominating and corporate governance committee, the compensation committee and the risk management committee will be divided as evenly as practicable between former Regions directors and former AmSouth directors.
 
Executive Officers of Regions
 
Following the merger, Jackson W. Moore, Chairman, President and Chief Executive Officer of Regions, will serve as Chairman of the Board of Regions and C. Dowd Ritter, Chairman of the Board, President and Chief Executive Officer of AmSouth, will serve as President and Chief Executive Officer of Regions. During the period that Mr. Moore is serving as Chairman, he will preside at all meetings of the board of directors and stockholders and have the right to attend all meetings of committees of the board of directors (since Mr. Moore will be deemed an executive officer of the combined company, the foregoing right will be subject to applicable law or stock exchange rules regarding the composition and executive sessions of committees) and participate in any regular meetings of management of the combined company. In the event that, prior to the third anniversary of the completion of the merger, Mr. Moore resigns or retires from his position as Chairman of the Board and Mr. Ritter is then continuing to serve as the President and Chief Executive Officer, Mr. Ritter will then also assume the position of Chairman of the Board. Until the third anniversary of the completion of the merger, removal of Mr. Moore or Mr. Ritter from their respective offices, and any determination not to nominate either as a director of the combined company, would require the affirmative vote of not less than 75% of the full board of directors.
 
Interests of AmSouth’s Directors and Officers in the Merger
 
AmSouth’s executive officers and directors may be deemed to have financial interests in the merger that are in addition to or different from their interests as stockholders of AmSouth. The AmSouth board of directors was aware of these financial interests and considered them, among other matters, in approving the merger agreement.

  C. Dowd Ritter Employment Agreement and Life Insurance Agreements
 
On May 24, 2006, C. Dowd Ritter, chairman, president and chief executive officer of AmSouth, executed a letter waiving his right under his employment agreement with AmSouth to serve as chairman of the board of directors of the company resulting from the merger so long as Jackson W. Moore continues to serve as chairman of the board of the combined company. Mr. Ritter’s employment agreement will be assumed by the combined company and will continue to govern the terms of his employment after the merger. As a result of Mr. Ritter’s letter, the occurrence of the merger will not entitle him to any termination or additional payment rights under his employment agreement so long as Mr. Moore or Mr. Ritter serves as chairman of the combined company. Mr. Ritter has also entered into two split-dollar life insurance agreements with AmSouth, one of which has a coverage amount of $6,770,034, payable at the death of the last of Mr. Ritter and his spouse and the other of which has a coverage amount of $3,339,795, payable at the death of Mr. Ritter. Upon a change in control, AmSouth’s obligation to pay associated premiums will become irrevocable, AmSouth is obligated to transfer ownership of the policy to an irrevocable trust and AmSouth will be obligated to fund the trust as necessary to pay all projected premiums.
 
Equity Based Compensation
 
Under AmSouth’s long term incentive compensation plans (“LTICPs”), AmSouth’s executive officers have been granted the following forms of equity based compensation: options to purchase AmSouth’s common shares, shares of restricted stock and performance unit awards. Approval of the merger by AmSouth’s stockholders will constitute a “change in control” under the LTICPs and will consequently have the following effects on the equity based compensation: all unvested options become immediately exercisable and will remain exercisable throughout their term; and any restriction periods imposed on shares of restricted stock will lapse. In addition, under the performance unit grant agreements, upon a change in control, the executive is entitled to immediate payout for the full term without pro-ration, based on company performance relative to goals in the year prior to the change in control, or, if greater, payout amount based on achievement of target performance.
 
Change in Control Agreements
 
Each of the following executive officers is a party to a change in control agreement with AmSouth: Candice W. Bagby, David B. Edmonds, John M. Gaffney, O.B. Grayson Hall, Jr., Susan Martinez, W. Charles Mayer, III, E .W. Stephenson, Jr., Geoffrey A. von Kuhn, William C. Wells, II and Alton E. Yother. Under the terms of these agreements, each executive officer is entitled to employment with Regions for two years following the change in control. In the event of termination of an executive’s employment by Regions without “cause” or by the executive for “good reason” (as these terms are defined in the change in control agreements), in each case prior to or within two years following the completion of the merger, the executive has a right to receive a cash payment equal to (i) three times (except in the case of Mr. Yother, two times) the sum of (x) the executive’s annual base salary, (y) the executive’s highest annual bonus out of the last three full fiscal years, and (z) a fair value competitive annual long term incentive grant; (ii) the actuarial present value of the executive’s aggregate benefits under the Supplemental Retirement Plan calculated under the assumption that the executive’s employment continued for the number of years remaining under the terms of the agreement and will be paid in lieu of any benefit under the Supplemental Retirement Plan; (iii) if the executive so elects, the executive’s aggregate benefits accrued through the date of termination under AmSouth’s Supplemental Thrift Plan paid in lieu of any benefit under the Plan itself; and (iv) three times (except in the case of Mr. Yother, two times) the sum of (x) the executive’s annual club dues bonus, and (y) the executive’s annual automobile allowance; (v) continued welfare benefits for the executive and the executive’s family for three years (except in the case of Mr. Yother, two years) from the date of termination; and (vi) relocation benefits or payment of accrued relocation benefits, outplacement assistance at the discretion of the executive and continued coverage under officer and director liability insurance, under the same terms and conditions and for the same amounts as in effect prior to termination, lasting through the expiration of the statutes of limitations on claims that might be brought against the executive, as well as indemnification and advancement of related litigation expenses. Each change in control agreement provides for full indemnification of the executive officer for excise taxes on “excess parachute payments” (within the meaning of section 280G of the Internal Revenue Code, as amended in 1986 (or the Code)), if applicable, made to the executive officer as a result of the merger.

Supplemental Retirement and Thrift Plans
 
Each of the executive officers is party to AmSouth’s Supplemental Retirement Plan and Supplemental Thrift Plan (collectively referred to as the SERPs). In the event of termination of employment of an executive under his or her change in control agreement, the executive’s benefits as defined under the Supplemental Retirement Plan will be calculated using actual years of credited service times 4% of average pay for each of the first 10 years and 1% of average pay for each additional year up to a total of 35 years of credited service and reduced by benefits from Social Security and other employers and will be payable as an actuarially reduced benefit as early as age 55 and as an unreduced benefit as of age 60 or later. In addition, in the event the executive is terminated within two years of a change in control, the executive is entitled to a lump sum payment of any retirement benefits under the Supplemental Thrift Plan.
 
Interests of Regions’ Management in the Merger
 
Regions’ Chairman and Chief Executive Officer may be deemed to have financial interests in the merger that are in addition to or different from his interests as a stockholder of Regions. The Regions board of directors was aware of these financial interests and considered them, among other matters, in approving the merger agreement.
 
Employment Agreement
 
In connection with the execution of the merger agreement, Jackson W. Moore, Regions’ Chief Executive Officer, entered into an employment agreement with a four-year term commencing upon completion of the merger, which will supersede his existing agreement. During the term, Mr. Moore will serve as the Chairman of the Board of Directors of the combined company and as a member of its board of directors. Mr. Moore will be provided with office space and secretarial services at both Regions’ headquarters and a location to be determined by Mr. Moore. During the term, Mr. Moore will receive annual base salary, annual bonus and long-term incentive compensation of not less than 75 percent of those provided to Regions’ chief executive officer, with newly granted long-term incentive awards to vest no later than the expiration of the four-year term. Mr. Moore will participate in all benefit, perquisite and other plans (other than certain retirement plans of AmSouth) generally applicable to Regions’ chief executive officer and other senior executives, including retiree medical benefits for him and his spouse and use of a corporate aircraft. On completion of the merger, all equity-based compensation awards will vest and options will remain exercisable in accordance with their terms. Following completion of the merger, Mr. Moore will be paid his accrued SERP benefit, the balance of his deferred stock account and the change-in-control benefits under his existing employment agreement. In addition, Regions will honor the existing terms of the trust agreement pertaining to the payment of premiums on Mr. Moore’s life insurance policy. In the event that, during the term, Mr. Moore’s employment is terminated by Regions without “cause” or by Mr. Moore for “good reason,” Mr. Moore will be paid a lump sum cash payment equal to the sum of (1) a pro rata bonus for the year of termination and (2) Mr. Moore’s annual base salary and average annual bonus as Chairman (or if no such bonus has been paid, his last bonus as chief executive officer) for the remainder of the term. In addition, upon such a termination all equity compensation awards will vest and remain exercisable for their full term.
 
Material Federal Income Tax Consequences of the Merger
 
The following is a summary of the material anticipated United States federal income tax consequences generally applicable to a U.S. Holder (as defined below) of AmSouth common stock with respect to the exchange of AmSouth common stock for Regions common stock pursuant to the merger. This discussion assumes that U.S. Holders hold their AmSouth common stock as capital assets within the meaning of section 1221 of the Code. This summary is based on the Code, administrative pronouncements, judicial decisions and Treasury Regulations, each as in effect as of the date of this joint proxy statement/prospectus. All of the foregoing are subject to change at any time, possibly with retroactive effect, and all are subject to differing interpretation. No advance ruling has been sought or obtained from the Internal Revenue Service (or the IRS), regarding the United States federal income tax consequences of the merger. As a result, no assurance can be given that the IRS would not assert, or that a court would not sustain, a position contrary to any of the tax consequences set forth below.
 
This summary does not address any tax consequences arising under United States federal tax laws other than United States federal income tax laws, nor does it address the laws of any state, local, foreign or other taxing

Table of Contents

jurisdiction. In addition, this summary does not address all aspects of United States federal income taxation that may apply to U.S. Holders of AmSouth common stock in light of their particular circumstances or U.S. Holders that are subject to special rules under the Code, such as holders of AmSouth common stock that are not U.S. Holders, holders that are partnerships or other pass-through entities (and persons holding their AmSouth common stock through a partnership or other pass-through entity), persons who acquired shares of AmSouth common stock as a result of the exercise of employee stock options or otherwise as compensation or through a tax-qualified retirement plan, persons subject to the alternative minimum tax, tax-exempt organizations, financial institutions, broker-dealers, traders in securities that have elected to apply a mark to market method of accounting, insurance companies, persons having a “functional currency” other than the U.S. dollar and persons holding their AmSouth common stock as part of a straddle, hedging, constructive sale or conversion transaction.
 
For purposes of this summary, a “U.S. Holder” is a beneficial owner of AmSouth common stock that is for United States federal income tax purposes:
 
  •  a United States citizen or resident alien;
 
  •  a corporation, or other entity taxable as a corporation for United States federal income tax purposes, created or organized under the laws of the United States or any state therein or the District of Columbia;
 
  •  an estate, the income of which is subject to United States federal income taxation regardless of its source; and
 
  •  a trust if (1) it is subject to the primary supervision of a court within the United States and one or more United States persons have the authority to control all substantial decisions of the trust, or (2) it was in existence on August 20, 1996 and has a valid election in effect under applicable Treasury Regulations to be treated as a United States person.
 
If a partnership (including any other entity treated as a partnership for United States federal income tax purposes) holds AmSouth common stock, the tax treatment of a partner will generally depend on the status of the partner and the activities of the partnership. Such a partner should consult its tax advisor.
 
The Merger
 
The merger is intended to qualify as a reorganization under section 368(a) of the Code. It is a condition to the completion of the merger that each of Regions and AmSouth receive an opinion dated the closing date from Wachtell, Lipton, Rosen & Katz and Sullivan & Cromwell LLP, respectively, to the effect that on the basis of facts, representations and assumptions set forth or referred to in the opinion, the merger will constitute a reorganization within the meaning of section 368(a) of the Code. These opinions will be based in part on representation letters provided by AmSouth and Regions and on customary factual assumptions. If any of the facts, representations or assumptions upon which the opinions are based are inconsistent with the actual facts, the tax consequences of the merger could be adversely affected, the opinions and this summary may not accurately describe the United States federal income tax treatment of the merger, and the tax consequences of the merger to U.S. Holders may be materially different from those described in this summary.
 
Assuming the merger qualifies as a reorganization within the meaning of section 368(a) of the Code, AmSouth and Regions will not recognize any gain or loss for United States federal income tax purposes as a result of the merger. Assuming the merger qualifies as a reorganization within the meaning of section 368(a) of the Code, the United States federal income tax consequences of the merger to U.S. Holders of AmSouth common stock are, in general, as follows:
 
  •  a U.S. Holder that receives Regions common stock in exchange for its shares of AmSouth common stock in the merger will not recognize gain or loss on the exchange, except to the extent the U.S. Holder receives cash instead of a fractional share interest in Regions common stock;
 
  •  the aggregate tax basis of the shares of Regions common stock received in the merger (including any fractional shares deemed received and redeemed for cash as described below) will be equal to the aggregate tax basis in the shares of AmSouth common stock surrendered in exchange for the Regions common stock; and


45


Table of Contents

 
  •  an exchanging U.S. Holder’s holding period in the Regions common stock received in the merger (including any fractional shares deemed received and redeemed for cash as described below) will include the holding period of the AmSouth common stock surrendered in exchange for Regions common stock.
 
Cash Instead of Fractional Shares
 
A U.S. Holder that receives cash instead of a fractional share should be treated as if such U.S. Holder had received a fractional share of Regions common stock and then exchanged such fractional share for cash in a redemption by Regions. Assuming that the deemed redemption of a fractional share of Regions common stock is treated as a sale or exchange, and not as a dividend, a U.S. Holder will generally recognize capital gain or loss on such deemed redemption of the fractional share in an amount equal to the difference between the amount of cash received instead of the fractional share and the U.S. Holder’s tax basis in the fractional share of Regions common stock. Such capital gain or loss will be long term capital gain or loss if the AmSouth common stock exchanged was held for more than one year at the effective time of the merger.
 
Information Reporting and Backup Withholding
 
A non-corporate U.S. Holder of AmSouth common stock may be subject to information reporting and backup withholding on any cash payments it receives instead of fractional share interests in Regions common stock. Backup withholding will not apply, however, if such U.S. Holder (a) furnishes a correct taxpayer identification number and properly certifies that it is not subject to backup withholding (generally on a substitute Form W-9) or (b) otherwise establishes an exemption from backup withholding.
 
Any amounts withheld under the backup withholding rules may be allowed as a refund or credit against the U.S. Holder’s United States federal income tax liability, provided such U.S. Holder timely furnishes the required information to the IRS. U.S. Holders should consult their tax advisors as to their qualifications for an exemption from backup withholding and the procedure for establishing an exemption.
 
Reporting Requirements
 
A U.S. Holder that receives Regions common stock as a result of the merger will be required to retain records pertaining to the merger and will be required to file with its United States federal income tax return for the year in which the merger takes place a statement setting forth certain facts relating to the merger.
 
Regulatory Matters
 
We have agreed to use our reasonable best efforts to obtain the regulatory approvals required to complete the merger. We refer to these approvals, along with the expiration of any statutory waiting periods related to these approvals, as the “requisite regulatory approvals.” These include approval from the Board of Governors of the Federal Reserve System, or Federal Reserve Board, and various other federal and state regulatory authorities. In addition to the application relating to that approval, we have filed or intend promptly to complete the filing of applications and notifications to obtain the other requisite regulatory approvals.
 
The merger cannot proceed in the absence of the requisite regulatory approvals. As discussed below, as of the date of this document, we estimate that we will need to make divestitures of branches in 15 markets with aggregate deposits of approximately $2.2 to $2.5 billion, and related loans and securities, in order to obtain approval of the merger by the Federal Reserve Board and the consent of the U.S. Department of Justice, or “DOJ”, although this is a preliminary estimate and the actual divestitures we will need to make may be more or less than this estimate.
 
Regions and AmSouth believe that they will be able to obtain all requisite regulatory approvals on a timely basis without the imposition of any condition that would have a material adverse effect on Regions or AmSouth. However, we cannot assure you as to whether or when the requisite regulatory approvals will be obtained, and, if obtained, we cannot assure you as to the date of receipt of any of these approvals or the absence of any litigation challenging them. Likewise, we cannot assure you that the DOJ, or a state attorney general will not attempt to challenge the merger on antitrust grounds, or, if such a challenge is made, as to the result of that challenge.
 
We are not aware of any other material governmental approvals or actions that are required prior to the parties’ completion of the merger other than those described below. We presently contemplate that if any additional


46


Table of Contents

governmental approvals or actions are required, these approvals or actions will be sought. However, we cannot assure you that any of these additional approvals or actions will be obtained.
 
Federal Reserve Board
 
Completion of the merger is subject to approval by the Federal Reserve Board pursuant to Sections 3 and 4 of the Bank Holding Company Act of 1956, as amended.
 
The Federal Reserve Board is prohibited from approving any transaction under the applicable statutes that (1) would result in a monopoly or be in furtherance of any combination or conspiracy to monopolize or to attempt to monopolize the business of banking in any part of the United States or (2) whose effect in any section of the United States may be to substantially lessen competition, or to tend to create a monopoly or result in a restraint of trade, unless the Federal Reserve Board finds that the anti-competitive effects of the transaction are clearly outweighed in the public interest by the probable effect of the transaction in meeting the convenience and needs of the communities to be served.
 
In addition, in reviewing the merger, the Federal Reserve Board will consider the financial and managerial resources of Regions and AmSouth and their subsidiary banks, the convenience and needs of the communities to be served, applicable overall capital and safety and soundness standards, the effectiveness of each company in combating money laundering activities, as well as Regions’ and AmSouth’s regulatory status, including legal and regulatory compliance.
 
Under the Community Reinvestment Act of 1977, as amended, the Federal Reserve Board will take into account our records of performance in meeting the credit needs of our entire community, including low- and moderate-income neighborhoods, served by our companies. Regions’ banking subsidiary has received a “satisfactory” rating, and AmSouth’s banking subsidiary received an “outstanding” rating, from their respective federal regulator in its most recent Community Reinvestment Act examination with respect to this criterion.
 
Furthermore, the Bank Holding Company Act and Federal Reserve Board regulations require published notice of, and the opportunity for public comment on, our application, and authorize the Federal Reserve Board to hold a public hearing or meeting if the Federal Reserve Board determines that a hearing or meeting would be appropriate. Any hearing or meeting or comments provided by third parties could prolong the period during which the application is under review by the Federal Reserve Board.
 
Pursuant to the Bank Holding Company Act, a transaction approved by the Federal Reserve Board may not be consummated until 30 days after such approval is received, during which time the DOJ may challenge the merger on antitrust grounds. With the approval of the Federal Reserve Board and the concurrence of the DOJ, the waiting period may be reduced to no less than 15 days. The commencement of an antitrust action would stay the effectiveness of such an approval unless a court specifically ordered otherwise. In reviewing the merger, the DOJ could analyze the merger’s effect on competition differently than the Federal Reserve Board, and thus it is possible that the DOJ could reach a different conclusion than the Federal Reserve Board regarding the merger’s effects on competition. A determination by the DOJ not to object to the merger may not prevent the filing of antitrust actions by private persons or state attorneys general.
 
We estimate, as of the date of this document, that we will need to make divestitures of branches in 15 markets with aggregate deposits of approximately $2.2 to $2.5 billion, and related loans and securities, in order to obtain approval of the merger by the Federal Reserve Board and the consent of the DOJ. These estimates are preliminary and are based on Federal Reserve Board decisions in other cases and published deposit figures and, while we currently believe this estimate is reasonable, there can be no assurance that the final amount will not be different than this preliminary estimate. Under Federal Reserve Board policy, the merger cannot be completed until there is an executed definitive agreement for the divestitures. Regions and AmSouth are working to receive clearance for the merger as promptly as practicable.
 
Department of Justice, Federal Trade Commission and Other Antitrust Authorities
 
Because the merger involves activities that are not subject to review by the Federal Reserve Board under Section 4 of the Bank Holding Company Act, it is partially subject to the Hart-Scott-Rodino Antitrust Improvements


47


Table of Contents

Act of 1976, and its related rules. Under that act, the merger cannot be completed until both Regions and AmSouth file notification of the proposed transaction with respect to these activities with the DOJ and the Federal Trade Commission, or FTC, and the specified waiting periods have expired or been terminated. Each of Regions and AmSouth will file its notification of the proposed transaction with the DOJ and the FTC.
 
Private parties also may seek to take legal action under the antitrust laws under some circumstances. Based upon an examination of information available relating to the businesses in which the companies are engaged, Regions and AmSouth believe that the completion of the merger will not violate U.S. antitrust laws. However, Regions and AmSouth can give no assurance that a challenge to the merger on antitrust grounds will not be made, or, if such a challenge is made, that Regions and AmSouth will prevail.
 
In addition, the merger may be reviewed by the state attorneys general in the various states in which Regions and AmSouth operate. While Regions and AmSouth believe there are substantial arguments to the contrary, these authorities may claim that there is authority, under the applicable state and federal antitrust laws and regulations, to investigate and/or disapprove the merger under the circumstances and based upon the review set forth in applicable state laws and regulations. There can be no assurance that one or more state attorneys general will not attempt to file an antitrust action to challenge the merger.
 
Other Regulatory Authorities
 
Applications or notifications are being filed with various state and/or foreign regulatory authorities and self-regulatory organizations, including the National Association of Securities Dealers, in connection with acquisitions or changes in control of subsidiaries of Regions and/or AmSouth, including banks, broker-dealers and insurance subsidiaries, that may be deemed to result from the merger. In addition, the merger may be reviewed by the attorneys general in the various states in which Regions and AmSouth own banking subsidiaries. These authorities may be empowered under applicable state laws and regulations to investigate or disapprove the merger under the circumstances and based upon the review provided for in applicable state laws and regulations.
 
Accounting Treatment
 
The merger will be accounted for as a “purchase” by Regions of AmSouth, as that term is used under U.S. Generally Accepted Accounting Principles, which we refer to as GAAP, for accounting and financial reporting purposes. As a result, the historical financial statements of Regions will continue to be the historical financial statements of Regions following the completion of the merger. The assets (including identifiable intangible assets) and liabilities (including executory contracts and other commitments) of AmSouth as of the effective time of the merger will be recorded at their respective fair values and added to those of Regions. Any excess of purchase price over the net fair values of AmSouth assets and liabilities is recorded as goodwill (excess purchase price). Financial statements of Regions issued after the merger will reflect such fair values and will not be restated retroactively to reflect the historical financial position or results of operations of AmSouth. The results of operations of AmSouth will be included in the results of operations of Regions beginning on the effective date of the merger.
 
Exchange of Certificates in the Merger
 
At or prior to the completion of the merger, Regions will cause to be deposited with the exchange agent certificates representing shares of Regions common stock for the benefit of the holders of certificates representing shares of AmSouth common stock and cash instead of any fractional shares that would otherwise be issued to AmSouth stockholders in the merger.
 
Promptly after the completion of the merger, Regions will cause the exchange agent to send transmittal materials to each holder of an AmSouth stock certificate for use in exchanging AmSouth stock certificates for certificates representing shares of Regions common stock and cash instead of fractional shares, if applicable. The exchange agent will deliver certificates for Regions common stock and/or a check instead of any fractional shares of Regions common stock once it receives the properly completed transmittal materials together with certificates representing a holder’s shares of AmSouth common stock.


48


Table of Contents

AmSouth stock certificates may be exchanged for Regions stock certificates with the exchange agent for up to six months after the completion of the merger. At the end of that period, any Regions stock certificates and cash will be returned to Regions. Any holders of AmSouth stock certificates who have not exchanged their certificates will be entitled to look only to Regions, and only as general creditors of Regions, for Regions stock certificates and any cash to be received instead of fractional shares of Regions common stock.
 
Starting 30 days after the merger, until you exchange your AmSouth stock certificates for Regions common stock certificates, you will not be able to vote on any matter on which Regions stockholders are entitled to vote and you will not receive any dividends or other distributions in respect of shares of Regions common stock. Once you exchange your AmSouth stock certificates for Regions stock certificates, you will receive, without interest, any dividends or distributions with a record date after the effective time of the merger and payable with respect to your shares, as well as any dividends with respect to Regions common stock declared before the effective time of the merger but unpaid.
 
If your AmSouth stock certificate has been lost, stolen or destroyed you may receive a Regions stock certificate upon the making of an affidavit of that fact. Regions may require you to post a bond in a reasonable amount as an indemnity against any claim that may be made against Regions with respect to the lost, stolen or destroyed AmSouth stock certificate.
 
Neither Regions nor AmSouth, nor any other person, will be liable to any former holder of AmSouth common stock for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws.
 
Treatment of AmSouth Options and Other Stock-Based Awards
 
Upon completion of the merger, each outstanding option to acquire AmSouth common stock, whether or not exercisable, will be assumed by Regions and converted into an option to acquire that number of whole shares of Regions common stock equal to the product of the number of shares of AmSouth common stock that were subject to the original AmSouth stock option multiplied by the exchange ratio at a per share exercise price equal to the exercise price per share of the original AmSouth stock option divided by the exchange ratio. Each converted AmSouth stock option will have the same terms and conditions as were in effect immediately prior to the completion of the merger, subject to any accelerated vesting as a result of the merger to the extent provided by the terms of the applicable AmSouth stock plan.
 
Each other AmSouth stock-based award will be converted into an award with respect to Regions common stock on the same basis as described for AmSouth stock options above.
 
As soon as practicable following the completion of the merger, Regions has agreed to file a registration statement to register the issuance of the shares of Regions common stock upon the exercise of the assumed AmSouth and Regions stock options and other rights.
 
Fractional Shares
 
Regions will not issue any fractional shares of Regions common stock. Instead, an AmSouth stockholder who would otherwise have received a fraction of a share of Regions common stock will receive an amount of cash equal to the fraction of a share of Regions common stock to which such holder would otherwise be entitled multiplied by the closing sale price per share of Regions common stock on the trading day immediately preceding the completion of the merger as reported on the NYSE Composite Transaction Tape.
 
Resales of Regions Stock by Affiliates
 
Stockholders of AmSouth who may be deemed to be affiliates of AmSouth and Regions, as defined under Rule 145 under the Securities Act, generally may not sell their shares of Regions common stock acquired in the merger except pursuant to an effective registration statement under the Securities Act or an applicable exemption from the registration requirements of the Securities Act, including Rules 144 and 145 promulgated by the SEC under the Securities Act. Affiliates include directors, executive officers, and beneficial owners of 10% or more of any class of capital stock.

Pursuant to the merger agreement, AmSouth has agreed to deliver a letter of agreement from each person it reasonably believes to be an “affiliate” by which that person will agree, among other things, not to offer to sell, transfer or otherwise dispose of any of the shares of Regions common stock distributed to him or her pursuant to the merger except in compliance with Rule 144 and Rule 145 under the Securities Act, in a transaction that is otherwise exempt from the registration requirements of the Securities Act, or in an offering registered under the Securities Act. Regions may place restrictive legends on its common stock certificates that are issued to persons who are deemed to be affiliates under the Securities Act. This document does not cover any resales of Regions common stock received in the merger by any person who may be deemed an affiliate of AmSouth and Regions.
 
Public Trading Markets
 
AmSouth common stock is currently listed on the New York Stock Exchange under the symbol “ASO.” Upon completion of the merger, AmSouth common stock will be delisted from the New York Stock Exchange and deregistered under the Securities Exchange Act of 1934, as amended. Regions common stock is listed on the New York Stock Exchange and trades under the symbol “RF.”
 
The shares of Regions common stock to be issued in connection with the merger will be freely transferable under the applicable securities laws, except for shares issued to any stockholder who may be deemed to be an affiliate of Regions or AmSouth, as discussed in “ — Resales of Regions Stock by Affiliates.”
 
Appraisal Rights
 
Under Delaware law, AmSouth stockholders are not entitled to appraisal rights in connection with the merger.
 
Litigation Relating to the Merger
 
On May 30, 2006, a putative stockholder class action lawsuit related to the merger agreement was filed in the United States District Court for the Northern District of Alabama against AmSouth and its directors. The lawsuit, captioned, Tucker v. AmSouth Bancorporation, et al. (Case No. CV-06-RRA-1039-S), alleges, among other things, that the exchange ratio agreed to in the merger agreement was inadequate and unfair to the AmSouth stockholders and that the individual defendants breached their duties to the stockholders in negotiating and approving the merger agreement. Two additional putative class actions, captioned David B. Shaev, IRA v. AmSouth Bancorporation, et al. (Case No. CV-06-P-1052-W) and Stone v. Ritter, et al. (Case No. CV200603121), were filed in the United States District Court for the Northern District of Alabama and in the Circuit Court of Jefferson County, Alabama, respectively. Like the Tucker complaint, the Shaev and Stone complaints allege claims for breach of fiduciary duty and seek injunctive, declaratory and other equitable relief. On June 22, 2006, the defendants moved to dismiss the Shaev action, and that action was dismissed without prejudice on July 6, 2006 at the request of the plaintiff. On June 23, 2006, the defendants filed a motion seeking a stay of all proceedings in the Stone action. That motion remains pending. On June 26, 2006 the defendants answered the complaint in the Tucker action by denying generally the allegations of the complaint. AmSouth believes that these lawsuits are without merit and intends to vigorously defend the actions.

THE MERGER AGREEMENT
 
The following describes material provisions of the merger agreement, which is attached as Annex A to this document and is incorporated by reference into this document. The rights and obligations of the parties are governed by the express terms and conditions of the merger agreement and not by this summary or any other information contained in this document. We urge you to read the merger agreement carefully and in its entirety.
 
The Merger
 
AmSouth will merge with and into Regions. Regions will be the surviving corporation and will continue its corporate existence under the laws of the State of Delaware under the name “Regions Financial Corporation,” and the separate corporate existence of AmSouth will terminate. Upon the completion of the merger, each share of AmSouth common stock outstanding, other than shares of AmSouth common stock held by either Regions or AmSouth, will be automatically converted into the right to receive 0.7974 shares of Regions common stock. All shares of AmSouth common stock converted into shares of Regions common stock will automatically be cancelled and retired as of the effective time of the merger. In addition, any shares of AmSouth common stock held by either AmSouth or Regions, or any of their respective subsidiaries, will be cancelled and retired as of the effective time of the merger.
 
Completion of the Merger
 
Unless the parties agree otherwise, the completion of the merger will take place at a time and place to be agreed by the parties, but no later than the third business day after all closing conditions have been satisfied or waived. The merger will be completed when we file a certificate of merger with the Delaware Secretary of State, unless we agree to a later time for the completion of the merger and specify that time in the certificate of merger. We currently expect to complete the merger in the fourth quarter of 2006, subject to receipt of required stockholder and regulatory approvals.
 
Conditions to Completion of the Merger
 
Our respective obligations to complete the merger are subject to the fulfillment or waiver of certain conditions, including:
 
  •  the adoption of the merger agreement by the holders of a majority of the outstanding shares of AmSouth common stock and Regions common stock;
 
  •  the receipt of all regulatory consents required to complete the merger, which consents must not be subject to any term or condition that would reasonably be likely to have a material adverse effect on the combined company after the completion of the merger, and the expiration of all waiting periods required by law;
 
  •  the absence of any law, statute, judgment, decree, administrative decision, award, injunction, writ or other order of any court, arbitrator, mediator, tribunal, administrative agency, or other governmental authority that prohibits, restrains, or makes illegal the completion of the merger;
 
  •  the effectiveness of the registration statement with respect to the Regions common stock to be issued in connection with the merger, the absence of any stop orders suspending the effectiveness of the registration statement, and the absence of any initiated, continuing or threatened action, suit, proceeding, or investigation by the SEC or any other governmental authority to suspend the effectiveness of the registration statement;
 
  •  the authorization for listing by the New York Stock Exchange of the shares of Regions common stock to be issued to the holders of AmSouth common stock upon completion of the merger, subject to official notice of issuance;
 
  •  the truth and correctness of the other party’s representations and warranties as of the date of the merger agreement and the date of the completion of the merger (with the exception of those representations and warranties that by their terms speak specifically as of the date of the merger agreement or some other date, which representations and warranties shall be true and correct as of such date), subject to the material adverse effect standard in the merger agreement;


51


Table of Contents

 
  •  the other party’s due performance and compliance with the agreements and covenants of the merger agreement in all material respects; and
 
  •  the receipt by each party from its legal advisor of a written legal opinion, dated as of the completion of the merger, to the effect that, on the basis of facts, representations and assumptions set forth or referred to in such opinion, the merger will constitute a reorganization within the meaning of section 368(a) of the Code.
 
Reasonable Best Efforts to Obtain Required Stockholder Votes
 
Each company has agreed to call a meeting of its stockholders as soon as reasonably practicable for the purpose of obtaining the required stockholder vote, and each party has agreed to use its reasonable best efforts to hold the meetings on the same date. In addition, each party has agreed to use its reasonable best efforts to obtain from its stockholders the required stockholder vote in favor of adoption of the merger agreement.
 
If either Regions or AmSouth fails to obtain the adoption of the merger agreement by its stockholders, Regions and AmSouth will in good faith use their reasonable best efforts to negotiate a restructuring of the merger and/or to resubmit the merger to the stockholders of Regions and AmSouth. The obligation does not require either party to alter or change the amount or kind of the merger consideration in a manner adverse to such party or its stockholders.
 
No Solicitation
 
Each of AmSouth and Regions has agreed that it will not, and will cause its subsidiaries and its subsidiaries’ officers, directors, representatives and affiliates not to:
 
  •  initiate, solicit, encourage or knowingly facilitate any inquiries or proposals with respect to any “acquisition proposal” (as defined below); or
 
  •  engage or participate in any negotiations concerning, or provide any confidential or nonpublic information or data to, or have or engage or participate in any discussions with, any person relating to any acquisition proposal.
 
Under the merger agreement, however, if either AmSouth or Regions receives an unsolicited bona fide written acquisition proposal, the recipient of such proposal may furnish nonpublic information or data and participate in negotiations or discussions to the extent that its board of directors concludes, in good faith, after receiving the advice of its outside counsel and its financial advisors, that the failure to do so would violate its fiduciary duties under applicable law, and provided that prior to furnishing such nonpublic information or data or participating in such negotiations or discussions, it enters a confidentiality agreement with the party that submitted the unsolicited bona fide written acquisition proposal on terms no less favorable than those of the confidentiality agreement between Regions and AmSouth.
 
Each of AmSouth and Regions has agreed to advise the other party within one day following receipt of any acquisition proposal or any inquiry which could reasonably be expected to lead to an acquisition proposal, including describing the substance of the acquisition proposal (including the identity of the proposing party), and to keep the other party apprised of any related developments, discussions and negotiations on a current basis.
 
For purposes of the merger agreement, an “acquisition proposal” means, other than transactions contemplated by the merger agreement, any proposal, offer or inquiry relating to, or any third party indication of interest in:
 
  •  any acquisition or purchase, direct or indirect, of twenty-five percent (25%) or more of the consolidated assets of a party and its subsidiaries or twenty-five percent (25%) or more of any class of equity or voting securities of a party or its subsidiaries whose assets, individually or in the aggregate, constitute more than twenty-five percent (25%) of the consolidated assets of the party;
 
  •  any tender offer (including a self-tender offer) or exchange offer that, if consummated, would result in a third party beneficially owning twenty-five percent (25%) or more of any class of equity or voting securities of a party or its subsidiaries whose assets, individually or in the aggregate, constitute more than twenty-five percent (25%) of the consolidated assets of the party;


52


Table of Contents

 
  •  a merger, consolidation, share exchange, business combination, reorganization, recapitalization, liquidation, dissolution or other similar transaction involving a party or its subsidiaries whose assets, individually or in the aggregate, constitute more than twenty-five percent (25%) of the consolidated assets of the party.
 
Termination
 
The merger agreement may be terminated, and the merger abandoned, by us at any time before the merger is completed if both of our boards of directors vote to do so. In addition, the merger agreement may be terminated, and the merger abandoned, by either of our boards of directors if:
 
  •  the merger has not been completed by May 31, 2007, unless the failure to complete the merger by such time is caused by a breach of the merger agreement by the terminating party;
 
  •  any regulatory consent required to complete the merger is denied, and the denial is final and nonappealable;
 
  •  (i) the board of directors of the other party fails to recommend that its stockholders vote in favor of approving and adopting the merger agreement or withdraws, modifies or qualifies its recommendation in a manner adverse to the terminating party, (ii) the other party fails substantially to comply with its obligation to call a meeting of its stockholders and to use its reasonable best efforts to cause its stockholders to adopt the merger agreement, or breaches its non-solicitation covenant, (iii) the other party negotiates or authorizes negotiations with a third party regarding an acquisition proposal, which negotiations continue for twenty business days, or (iv) the board of directors of the other party recommends or endorses an acquisition proposal other than the merger agreement;
 
  •  the stockholders of either party fail to adopt the merger agreement, and that party substantially engages in bad faith in breach of its obligation to use its reasonable best efforts to negotiate a restructuring of the transaction and to resubmit the transaction to its stockholders for adoption and approval; or
 
  •  the other party breaches any representation, warranty, covenant or agreement contained in the merger agreement, which breach would, if it were occurring on the date of the completion of the merger, result in the failure of the conditions to the terminating party’s obligation to complete the merger, and which cannot be or has not been cured within 30 days after the giving of written notice to the breaching party of such breach.
 
Effect of Termination.  If the merger agreement is terminated and abandoned, it will become void and there will be no liability on the part of AmSouth or Regions or their respective subsidiaries, directors or officers, except that:
 
  •  designated provisions of the merger agreement will survive the termination, including provisions relating to the payment of fees and expenses, non-survival of the representations and warranties, confidential treatment of information and the representation of the parties with respect to brokers and finders;
 
  •  termination will not relieve a breaching party from liability for any uncured willful breach of the merger agreement;
 
  •  AmSouth and Regions, and their respective representatives, will keep confidential and will not use any information obtained from the other party for any purpose unrelated to the completion of the transactions contemplated by the merger agreement. AmSouth and Regions will also promptly return or destroy all documents, copies of documents and work papers containing confidential information and data regarding the other party; and
 
  •  the stock option agreements will remain in effect in accordance with their terms.
 
Bylaw Amendments
 
In connection with entering into the merger agreement, Regions’ board of directors approved changes to the Regions bylaws which will become effective upon the completion of the merger. These bylaw amendments will affect the corporate governance agreements described below. Following completion of the merger, the affirmative vote of at least 75% of the full board of directors of Regions will be required to amend, repeal or modify the bylaw


53


Table of Contents

provisions providing for these governance arrangements, or to adopt any bylaw provision inconsistent with these arrangements.
 
  •  Composition of the Board of Directors.  Upon completion of the merger, the board of directors of Regions will consist of twelve current directors of Regions designated by Regions (plus up to one additional director to be added prior to the completion of the merger with the mutual agreement of Regions and AmSouth), and nine current directors of AmSouth designated by AmSouth (plus up to one additional director to be added prior to the completion of the merger with the mutual agreement of Regions and AmSouth). The former Regions directors and former AmSouth directors will be apportioned among the three classes of the Regions board of directors as equally as possible.
 
  •  Replacement of Vacant Directorships.  Until the third anniversary of the completion of the merger, if there is a vacancy created by the cessation of service of a Regions designee, a majority of the remaining Regions designees will propose a nominee to the nominating and corporate governance committee of the Regions board of directors to fill the vacant position, and if there is a vacancy created by the cessation of service of an AmSouth designee, a majority of the remaining AmSouth designees will propose a nominee to the nominating and corporate governance committee of the Regions board of directors to fill the vacant position.
 
  •  Committees of the Board of Directors.  Until the third anniversary of the completion of the merger, the chairmanships of the following committees of the board of directors of Regions will be divided evenly between individuals who are former Regions directors and those who are former AmSouth directors: the audit committee, the nominating and corporate governance committee, the compensation committee and the risk management committee. Also until the third anniversary of the completion of the merger, the total membership on the nominating and governance committee will include an equal number of former Regions directors and former AmSouth directors. In addition, it is the intention of Regions and AmSouth that until the third anniversary of the completion of the merger, subject to any relevant independence and expertise requirements under applicable law or stock exchange rule, the membership of each of the audit committee, the nominating and corporate governance committee, the compensation committee and the risk management committee will be divided as evenly as practicable between former Regions directors and former AmSouth directors.
 
  •  Executive Officers of Regions.  Jackson W. Moore, Chairman, President and Chief Executive Officer of Regions, will serve as Chairman of the Board of Regions and C. Dowd Ritter, Chairman of the Board, President and Chief Executive Officer of AmSouth, will serve as President and Chief Executive Officer of Regions following the merger. During the period that Mr. Moore is serving as Chairman, he will preside at all meetings of the board of directors and stockholders and have the right to attend all meetings of committees of the board of directors (since Mr. Moore will be deemed an executive officer of the combined company, the foregoing right will be subject to applicable law or stock exchange rules regarding the composition and executive sessions of committees) and participate in any regular meetings of management of the combined company. In the event that, prior to the third anniversary of the completion of the merger, Mr. Moore resigns or retires from his position as Chairman of the Board and Mr. Ritter is then continuing to serve as the President and Chief Executive Officer, Mr. Ritter will then also assume the position of Chairman of the Board. Until the third anniversary of the completion of the merger, removal of Mr. Moore or Mr. Ritter from their respective offices, and any determination not to nominate either as a director of the combined company, would require the affirmative vote of not less than 75% of the full board of directors.
 
Other Covenants and Agreements
 
Each of AmSouth and Regions has made customary agreements that place restrictions on it and its subsidiaries until the effective time of the merger. In general, AmSouth and Regions and their respective subsidiaries are required to use their reasonable best efforts to maintain and preserve intact their business organizations, assets, employees and relationships with customers, suppliers, employees and business associates. In addition, AmSouth and Regions and their respective subsidiaries are required to conduct their business in the ordinary course and to take no action that would adversely affect or delay the ability of any party to obtain any required consents or perform its covenants and agreements under the merger agreement or complete the merger on a timely basis. Each of

  •  sell, transfer, mortgage, encumber or otherwise dispose of any part of its business or any of its properties or assets, or cancel, release or assign any indebtedness or any claims against any person or entity other than a wholly owned subsidiary, except in the ordinary course of business or pursuant to current contracts or as may be required in connection with complying with its obligations under the merger agreement;
 
  •  incur any indebtedness, become responsible for the obligations of another or make any loan or advance, in all cases other than in the ordinary course of business;
 
  •  restructure or materially change its investment securities or other financial portfolio or its interest rate exposure;
 
  •  terminate, waive or knowingly fail to use reasonable best efforts to enforce any material provision of any material contract, other than in the ordinary course of business;
 
  •  other than as required under current benefit plans and subject to certain exceptions, increase the compensation or benefits of any of its officers, employees or directors, pay any pension or retirement allowance not required by any existing benefit plan, become a party to or amend any benefit plan or contract or employment agreement, or accelerate vesting of any stock options or stock-based awards;
 
  •  settle any material litigation;
 
  •  change its tax or financial accounting methods, other than as required by law;
 
  •  file or amend any tax return other than in the ordinary course of business, make, change or revoke any material tax election, settle or compromise any material tax liability, agree to an extension of the statute of limitations with respect to the assessment or collection of material taxes or make or surrender any claim for a tax refund;
 
  •  take any action or fail to take any action that is intended or may be reasonably expected to result in any of the conditions to the merger not being satisfied, or take any action that would reasonably be expected to prevent the merger from qualifying as a reorganization for federal income tax purposes;
 
  •  agree to take, or adopt any resolutions by the board of directors in support of, any of the actions prohibited by the preceding bullet points.
 
The merger agreement also contains mutual agreements relating to coordinating the payment schedule for ordinary course dividends, filing required regulatory applications and obtaining required regulatory consents, access to information of the other party and public announcements with respect to the transactions contemplated by the merger agreement.

Representations and Warranties
 
The merger agreement contains reciprocal representations and warranties of AmSouth and Regions relating to their respective businesses, including as relates to:
 
  •  corporate organization, standing and power, and subsidiaries,
 
  •  requisite corporate authority to enter into the merger agreement and stock option agreements and to complete the contemplated transactions,
 
  •  capitalization,
 
  •  securities law filings and financial statements,
 
  •  absence of certain changes,
 
  •  tax matters,
 
  •  absence of any actions reasonably likely to prevent the merger from qualifying as a tax-free reorganization or reasonably likely to impede or materially delay the receipt of any required regulatory consents,
 
  •  environmental matters,
 
  •  compliance with permits, laws and orders, and reporting requirements,
 
  •  labor relations,
 
  •  employee benefit matters,
 
  •  material contracts,
 
  •  litigation,
 
  •  reports to governmental authorities,
 
  •  intellectual property,
 
  •  state takeover laws,
 
  •  fairness opinions,
 
  •  insurance, and
 
  •  brokers and finders.
 
With the exception of specified representations relating to capitalization, corporate authority and fairness opinions that must be true and correct in all material respects, and representations relating to absence of conflict with organizational documents and absence of certain changes reasonably likely to have a material adverse effect which must be true and correct in all respects, no representation will be deemed untrue or incorrect as a consequence of the existence or absence of any fact or event unless that fact or event, individually or taken together with all other facts or events, has had or is reasonably likely to have a material adverse effect on the company making the representation.
 
The representations described above and included in the merger agreement were made for purposes of the merger agreement and are subject to qualifications and limitations agreed to by the respective parties in connection with negotiating the terms of the merger agreement. In addition, certain representations and warranties were made as of a specific date, may be subject to a contractual standard of materiality different from what might be viewed as material to stockholders, or may have been used for purposes of allocating risk between the respective parties rather than establishing matters as facts. This description of the representations and warranties, and their reproduction in the copy of the merger agreement attached to this document as Annex A, are included solely to provide investors with information regarding the terms of the merger agreement. Accordingly, the representations and warranties and other provisions of the merger agreement should not be read alone, but instead should only be read together with the information provided elsewhere in this document and in the documents incorporated by reference into this

document, including the periodic and current reports and statements that Regions and AmSouth file with the SEC. See “Where You Can Find More Information” on page   .
 
Regions Employee Benefit Plans
 
The merger agreement provides that after the completion of the merger, Regions, at its election, may, with respect to AmSouth employees who become Regions employees following the completion of the merger, either:
 
  •  provide employee benefits under Regions compensation and benefit plans on terms and conditions that are the same for similarly situated employees of Regions, or
 
  •  maintain for the benefit of such continuing AmSouth employees the compensation and benefit plans maintained by AmSouth immediately prior to the completion of the merger.
 
Regions will recognize, for purposes of participation, vesting and benefit accrual (but not for benefit accrual with respect to any plan in which such credit would result in a duplication of benefits) all service with AmSouth as service with Regions. This recognition will not cause Regions’ tax-qualified defined benefit pension plan (which is not open to new participants) to be opened to new participants.
 
Expenses and Fees
 
In general, each party will be responsible for all expenses incurred by it in connection with the negotiation and completion of the transactions contemplated by the merger agreement. However, AmSouth and Regions will each pay one-half of the costs incurred in connection with the preparation (including printing and filing) of this document.
 
Possible Alternative Merger Structure
 
The merger agreement provides that AmSouth and Regions may mutually agree to change the structure of the merger. However, no change may be made that:
 
  •  alters or changes the number of shares of Regions common stock into which shares of AmSouth common stock will be converted in the merger,
 
  •  adversely affects the tax treatment of AmSouth or Regions or their respective stockholders pursuant to the merger agreement, or
 
  •  materially impedes or delays completion of the merger in a timely manner.
 
Amendment or Waivers
 
The merger agreement may be amended or modified, in accordance with applicable law, by our written agreement, except that any amendment that would require the approval of either company’s stockholders will not be made unless such required approval is first obtained. The provisions of the merger agreement may be waived by the party benefited by those provisions, except as would be prohibited under applicable law.

THE STOCK OPTION AGREEMENTS
 
The following description, which sets forth the material provisions of the stock option agreements under which AmSouth has granted an option to Regions to purchase shares of AmSouth common stock in specified circumstances, and Regions has granted an option to AmSouth to purchase shares of Regions common stock in specified circumstances, is subject to the full text of, and qualified in its entirety by reference to, the stock option agreements, which are attached to this document as Annexes B and C, respectively, and each of which is incorporated by reference into this document. We urge you to read the stock option agreements carefully and in their entirety, as they are the legal documents governing the stock options.
 
The Stock Options
 
When we entered into the merger agreement, we also entered into reciprocal stock option agreements. Under the terms of the stock option granted by AmSouth to Regions, Regions may purchase up to 69,027,842 shares of AmSouth common stock at an exercise price equal to the lesser of $28.90 per share or the closing sale price of the common stock on the NYSE Composite Transaction Tape on the trading day immediately preceding the exercise date. Under the terms of the stock option granted by Regions to AmSouth, AmSouth may purchase up to 90,767,194 shares of Regions common stock at an exercise price equal to the lesser of $35.53 per share or the closing sale price of the common stock on the NYSE Composite Transaction Tape on the trading day immediately preceding the exercise date. However, the number of shares issuable upon exercise of the two options cannot respectively exceed 19.9% of AmSouth and Regions common stock outstanding without giving effect to any shares issued under the options. In the event that any additional shares of common stock are either issued or redeemed after the date of the stock option agreements, the number of the relevant shares of common stock subject to the option will be adjusted so that such number equals 19.9% of the number of relevant shares of common stock then issued and outstanding without giving effect to any shares of common stock subject to or issued under the option. The terms of the stock option agreements are identical in most respects and are summarized below.
 
Purpose of the Stock Option Agreements
 
The stock option agreements may have the effect of making an acquisition or other business combination of AmSouth or Regions by a third party more costly because of the need in any transaction to acquire any shares of common stock issued under the stock option agreements or because of any cash payments made under the stock option agreements. The stock option agreements may, therefore, discourage third parties from proposing an alternative transaction to the merger.
 
To our knowledge, no event giving rise to the right to exercise either stock option has occurred as of the date of this document.
 
Exercise; Expiration
 
Each grantee of the option may exercise its respective option in whole or in part if both an Initial Triggering Event and a Subsequent Triggering Event occur prior to the occurrence of an Exercise Termination Event, as these terms are described below. The purchase of any shares of AmSouth common stock or Regions common stock under the options is subject to compliance with applicable law, which may require regulatory approval.
 
The term “Initial Triggering Event” generally means the following:
 
  •  an option issuer or any of its subsidiaries, without the grantee’s prior written consent, enters into an agreement to engage in an “Acquisition Transaction” (as defined below) with a third party, or an option issuer’s board of directors recommends that its stockholders approve or accept any Acquisition Transaction with any person other than the grantee;
 
  •  an option issuer or any of its subsidiaries, without the grantee’s prior written consent, authorizes, recommends, proposes or publicly announces its intention to authorize, recommend or propose, to engage in an Acquisition Transaction with any person other than the grantee or a grantee subsidiary, or an option issuer’s board of directors publicly withdraws or modifies, or publicly announces its intention to withdraw or modify,


58


Table of Contents

  in a manner adverse to the grantee, its recommendation that its stockholders approve the transactions contemplated by the merger agreement;
 
  •  any third party acquires beneficial ownership or the right to acquire beneficial ownership of 10% or more of the outstanding shares of the option issuer’s common stock;
 
  •  any person, other than the grantee, publicly makes a bona fide proposal to an option issuer or an option issuer’s stockholders to engage in an Acquisition Transaction;
 
  •  after the receipt by an option issuer or its stockholders of any bona fide inquiry or proposal from a third party to an option issuer or any of its subsidiaries to engage in an Acquisition Transaction, such option issuer breaches any covenant or obligation contained in the merger agreement, the breach entitles the grantee to terminate the merger agreement and the breach has not been cured prior to the date of written notice of the grantee’s intention to exercise the option; or
 
  •  any third person, without the written consent of the grantee, files an application or notice with the Federal Reserve Board or other federal or state bank regulatory authority, which application or notice has been accepted for processing, for approval to engage in an Acquisition Transaction.
 
As used in the stock option agreements, the term “Acquisition Transaction” means:
 
  •  a merger, consolidation or share exchange, or any similar transaction, involving the option issuer or any of its significant subsidiaries;
 
  •  a purchase, lease or other acquisition or assumption of all or a substantial portion of the assets or deposits of the option issuer or any of its significant subsidiaries;
 
  •  a purchase or other acquisition of securities representing 10% or more of the voting power of the option issuer; or
 
  •  any substantially similar transaction, except that any substantially similar transaction involving only the option issuer and one or more of its wholly-owned subsidiaries or involving only any two or more of these wholly-owned subsidiaries will not be deemed to be an Acquisition Transaction, provided that it is not entered into in violation of the merger agreement.
 
The stock option agreements generally define the term “Subsequent Triggering Event” to mean any of the following events or transactions:
 
  •  the acquisition by a third party of beneficial ownership of 20% or more of the outstanding shares of the option issuer’s common stock; or
 
  •  the option issuer enters into an agreement to engage in an Acquisition Transaction with a third party, or its board of directors recommends that its stockholders approve or accept any Acquisition Transaction or proposed Acquisition Transaction other than the merger agreement. For this purpose, the percentage referred to in the definition of Acquisition Transaction is 20% instead of 10%.
 
The stock option agreements define the term “Exercise Termination Event” to mean any of the following:
 
  •  completion of the merger;
 
  •  termination of the merger agreement prior to the occurrence of an Initial Triggering Event, other than a termination of the merger agreement described in clauses (i) and (ii) in the next bullet;
 
  •  the passage of 18 months after termination of the merger agreement if termination occurred after the occurrence of an Initial Triggering Event or is a termination of the merger agreement resulting from:
 
(i) the failure of the option issuer’s board of directors to recommend that its stockholders vote in favor of approving and adopting the merger agreement or its withdrawal or modification of its recommendation in a manner adverse to the other party, the failure of the option issuer substantially to comply with its obligation to call a meeting of its stockholders and to cause its stockholders to adopt the merger agreement, a breach by the option issuer of its non-solicitation covenant, the option issuer’s negotiation with a third party regarding


59


Table of Contents

an acquisition proposal which negotiations do not cease within 20 business days, or the recommendation by the option issuer’s board of an acquisition proposal other than the merger agreement, or
 
(ii) the option issuer’s willful and material breach of the merger agreement, which breach would, if it were occurring on the date of the completion of the merger, result in the failure of the related condition to the other party’s obligation to complete the merger, and which cannot be or has not been cured within 30 days.
 
If either option becomes exercisable, it may be exercised, in whole or in part, within 180 days following the Subsequent Triggering Event. Each grantee’s right to exercise its option and certain other rights under the stock option agreements are subject to an extension to the extent necessary in order to obtain required regulatory approvals and comply with applicable regulatory waiting periods, to avoid liability under the short-swing trading restrictions contained in Section 16(b) of the Exchange Act, and when there exists an order that prohibits or delays exercise of such right.
 
Rights Under the Stock Option Agreements
 
In the event of a repurchase event (as defined below), and prior to an Exercise Termination Event subject to extension as described above, following a request of a grantee, an option issuer may be required to repurchase its option and all or any part of the shares issued under the option. The repurchase of the option will be at a price equal to the number of shares for which the option may be exercised multiplied by the amount by which the market/offer price, as that term is defined in the stock option agreements, exceeds the exercise price. At the request of the owner of option shares within 90 days of the occurrence of a repurchase event, an option issuer may be required to repurchase such number of the option shares from the owner as designated by the owner at a price equal to the market/offer price, as that term is defined in the stock option agreement, multiplied by the number of option shares so designated. The term “Repurchase Event” is defined to mean:
 
  •  the completion of an Acquisition Transaction involving an option issuer, except that for this purpose the reference to 10% in the definition of Acquisition Transaction is deemed to be 50%; or
 
  •  the acquisition by any person of beneficial ownership of 50% or more of the then-outstanding shares of common stock of an option issuer.
 
The stock option agreements also provide that a grantee may, at any time during which an option issuer would be required to repurchase the option or any option shares upon proper request or notice, subject to extension as described above, surrender the option and any shares issued under the option held by the grantee to the option issuer for a cash payment equal to $343,962,190, adjusted for the aggregate purchase price previously paid by such grantee with respect to any option shares and gains on sales of stock purchased under the option. However, a grantee may not exercise its surrender right if the option issuer repurchases the option, or a portion of the option, in accordance with the option issuer’s repurchase obligations described above.
 
If, prior to an Exercise Termination Event, an option issuer enters into certain mergers, consolidations or other transactions, certain fundamental changes in its capital stock occur, or it sells all or substantially all of its assets to any person other than the grantee or one of the grantee’s subsidiaries, the option will be converted into, or be exchanged for, a substitute option, at the grantee’s election, of:
 
  •  the continuing or surviving corporation of a consolidation or merger with the option issuer,
 
  •  the option issuer in a merger in which it is the continuing or surviving person,
 
  •  the transferee of all or substantially all of the assets of the option issuer, or
 
  •  any person that controls any of these entities, as the case may be.

The substitute option will have the same terms as the original option (including a repurchase right, but based on the closing price of the common stock of the substitute issuer). However, if, because of legal reasons, the terms of the substitute option cannot be the same as those of the original option, the terms of the substitute option will be as similar as possible and at least as advantageous to the grantee as the original option. Also, the number of shares exercisable under the substitute option is capped at 19.9% of the shares of common stock outstanding prior to exercise. In the event this cap would be exceeded, the issuer of the substitute option will pay the grantee the difference between the value of a capped and non-capped option.
 
The stock option agreements provide that the total profit, as defined in the stock option agreements, realized by a grantee as a result of a stock option agreement may in no event exceed $393,099,645.

DESCRIPTION OF REGIONS CAPITAL STOCK
 
In this section, we describe the material features and rights of the Regions capital stock after the merger. This summary is qualified in its entirety by reference to applicable Delaware law, Regions’ certificate of incorporation and Regions’ bylaws, as described below. See “Where You Can Find More Information.”
 
General
 
Regions is currently authorized to issue 1.5 billion shares of common stock having a par value of $0.01 per share and 10 million shares of preferred stock having a par value of $1.00 per share. Each share of Regions common stock has the same relative rights as, and is identical in all respects to, each other share of Regions common stock.
 
Common Stock
 
Dividends.  Subject to certain regulatory restrictions, Regions can pay dividends out of statutory surplus or from certain net profits if, as and when declared by its board of directors. Funds for Regions dividends will be generally provided through dividends from its subsidiary institutions. The payment of dividends by Regions’ subsidiary institutions is subject to limitations which are imposed by law and applicable regulation. Following the completion of the merger, the holders of common stock of Regions will be entitled to receive and share equally in such dividends as may be declared by the board of directors of Regions out of funds legally available therefor. If Regions issues preferred stock, the holders thereof may have a priority over the holders of the common stock with respect to dividends.
 
Voting Rights.  The holders of common stock of Regions possess exclusive voting rights in Regions. They elect the Regions board of directors and act on such other matters as are required to be presented to them under Delaware law, Regions’ organizational documents or as are otherwise presented to them by the board of directors. Each holder of common stock is entitled to one vote per share and does not have any right to cumulate votes in the election of directors. If Regions issues preferred stock, holders of the preferred stock may also possess voting rights. Specified matters in Regions’ certificate of incorporation require a 75% stockholder vote. See “The Merger Agreement — Bylaw Amendment” and “Comparison of Stockholders’ Rights.”
 
Liquidation.  In the event of liquidation, dissolution or winding up of Regions, the holders of its common stock would be entitled to receive, after payment or provision for payment of all of its debts and liabilities, all of the assets of Regions available for distribution. If preferred stock is issued, the holders thereof may have a priority over the holders of the Regions common stock in the event of liquidation or dissolution.
 
Preemptive Rights.  Holders of Regions common stock are not entitled to preemptive rights with respect to any shares which may be issued.
 
Preferred Stock
 
Shares of Regions preferred stock may be issued with such designations, powers, preferences and rights as the Regions board of directors may from time to time determine. The Regions board of directors can, without stockholder approval, issue preferred stock with voting, dividend, liquidation and conversion rights which could dilute the voting strength of the holders of the common stock and may assist management in impeding an unsolicited takeover or attempted change in control.

PRO FORMA FINANCIAL INFORMATION
REGIONS FINANCIAL CORPORATION AND AMSOUTH BANCORPORATION
 
The following Unaudited Pro Forma Condensed Combined Consolidated Statement of Financial Condition combines the historical Consolidated Statement of Financial Condition of Regions and its subsidiaries and the historical Consolidated Statement of Financial Condition of AmSouth and its subsidiaries giving effect to the merger as if it had occurred on March 31, 2006, as an acquisition by Regions of AmSouth using the purchase method of accounting and giving effect to the related pro forma adjustments described in the accompanying Notes to the Unaudited Pro Forma Condensed Combined Consolidated Financial Statements.
 
The following Unaudited Pro Forma Condensed Combined Consolidated Statements of Income for the three months ended March 31, 2006, and the year ended December 31, 2005, combine the historical Consolidated Statements of Income of Regions and its subsidiaries and AmSouth and its subsidiaries giving effect to the merger as if the merger had become effective at the beginning of each period presented, as an acquisition by Regions of AmSouth using the purchase method of accounting and giving effect to the related pro forma adjustments described in the accompanying Notes to the Unaudited Pro Forma Condensed Combined Consolidated Financial Statements.
 
The unaudited pro forma condensed combined consolidated financial statements included herein are presented for informational purposes only. This information includes various estimates and may not necessarily be indicative of the financial position or results of operations that would have occurred if the merger had been consummated on the date or at the beginning of the period indicated or which may be attained in the future. The unaudited pro forma condensed combined consolidated financial statements and accompanying notes should be read in conjunction with and are qualified in their entirety by reference to the historical financial statements and related notes thereto of Regions and its subsidiaries and AmSouth and its subsidiaries, such information and notes thereto incorporated by reference herein.
 
We anticipate that the merger will provide the combined company with financial benefits that include reduced operating expenses. The pro forma information, while helpful in illustrating the financial characteristics of the combined company under one set of assumptions, does not reflect the benefits of expected cost savings or opportunities to earn additional revenue and, accordingly, does not attempt to predict or suggest future results. It also does not necessarily reflect what the historical results of the combined company would have been had our companies been combined during these periods.
 
For purposes of this analysis we have assumed that we will need to make divestitures of branches with aggregate deposits of approximately $2.5 billion, and related loans and securities, in order to obtain approval of the merger by the Federal Reserve Board. This assumption represents the high-end of our currently estimated range of $2.2 to $2.5 billion for divestitures; these estimates are preliminary and are based on Federal Reserve Board decisions in other cases and published deposit figures and, while we currently believe this estimate is reasonable, there can be no assurance that the final amount will not be different than this preliminary estimate. Under Federal Reserve Board policy, the merger cannot be completed until there is an executed definitive agreement for the divestitures. Regions and AmSouth are working to receive clearance for the merger as promptly as practicable.

and the Three Months Ended March 31, 2006
 
Note 1.
 
The merger will be accounted for as an acquisition by Regions of AmSouth using the purchase method of accounting reflecting the acquisition by Regions of AmSouth and, accordingly, the assets and liabilities of AmSouth will be recorded at their respective fair values on the date the merger is completed. The merger will be effected by the issuance of Regions $0.01 par value common stock to AmSouth stockholders. Each share of AmSouth common stock will be exchanged for 0.7974 of a share of Regions common stock. The shares of Regions common stock issued to effect the merger will be recorded at $35.00 per share. This amount was determined by averaging the price of shares of Regions common stock over a four-day period surrounding the date the merger was announced.
 
The pro forma financial information includes estimated adjustments to record assets and liabilities of AmSouth at their respective fair values. The pro forma adjustments included herein are subject to change as additional information becomes available and as additional analyses are performed.
 
The final allocation of the purchase price will be determined after the merger is completed and additional analyses are performed to determine the fair values of AmSouth’s tangible and identifiable intangible assets and liabilities as of the date the merger is completed. Changes in the fair value of the net assets of AmSouth as of the date of the merger will change the amount of purchase price allocable to excess purchase price. The further refinement of transaction costs will change the amount of excess purchase price recorded. In addition, changes in AmSouth’s stockholders’ equity, including net income, between April 1, 2006 and the date of the merger will also change the amount of excess purchase price recorded. The final adjustments may be materially different from the unaudited pro forma adjustments presented herein.
 
The pro forma financial information for the merger is included only as of and for the three months ended March 31, 2006, and for the year ended December 31, 2005. The unaudited pro forma information is not necessarily indicative of the results of operations of the combined financial position that would have resulted had the merger been completed at the beginning of the applicable periods presented, nor is it necessarily indicative of the results of operations in future periods or the future financial position of the combined company.
 
Note 2.
 
The pro forma financial information reflects the issuance of 276,370,895 shares of Regions common stock on March 31, 2006, with an aggregate par value of approximately $2.8 million. The table below provides the calculation of the number of shares issued:

Regions common stock issued
            276,370,895  
                 
 
The pro forma financial information includes adjustments to stockholders’ equity for the elimination of AmSouth’s accumulated other comprehensive loss of $192.3 million, the immediate vesting of AmSouth’s unearned stock compensation of $18.1 million, the retirement of AmSouth treasury stock of $1,249.5 million and the elimination of AmSouth’s undivided profits of $3,917.3 million. All of these amounts have been reclassified into surplus. In addition to these equity adjustments, $228.9 million was included in the purchase price for the estimated fair value of all unexercised AmSouth stock options assumed upon the merger and $205.6 million was included in the purchase price for estimated transaction costs. The $228.9 million is a preliminary estimate based on the intrinsic value of the options. The final estimate of fair value of the AmSouth stock options will be based on the Black-Scholes option model.

The purchase accounting adjustments included in the pro forma statement of financial condition include adjustments to securities, loans, interest-bearing deposits, and long-term borrowings of ($169.3) million, ($478.2) million, ($97.5) million, and $45.7 million, respectively. These adjustments are based on preliminary valuations performed as of March 31, 2006. The adjustments recorded for these assets and liabilities on the merger date could vary significantly from the pro forma adjustments included herein depending on changes in interest rates and the components of the assets and liabilities. An analysis to determine the purchase accounting adjustment to AmSouth’s property and equipment has not yet been completed. Upon completion of this analysis, adjustments may be recorded which will affect the purchase price allocation.
 
The purchase accounting adjustments include a core deposit intangible asset adjustment of $881.1 million. The adjustment includes the establishment of a core deposit intangible asset of $882.6 million less AmSouth’s recorded core deposit intangible of $1.5 million. The $882.6 million was calculated by applying a premium of 3.0% to AmSouth’s core deposits. Core deposits are defined as all non-interest bearing deposits and interest-bearing transaction accounts excluding non-core time deposits. The amortization of the core deposit intangible in the pro forma statements of operations is assumed to be over a ten year period using an accelerated method. An analysis to

determine if other identifiable intangible assets exist has not yet been completed. Upon completion of this analysis, additional intangible assets may be recorded which will affect the purchase price allocation.
 
The pro forma statement of financial condition includes an estimated $205.6 million adjustment to reflect the amounts allocated to liabilities expected to be assumed in the acquisition. The estimated liabilities assumed in the merger consist of personnel related costs which include involuntary termination benefits for AmSouth’s employees severed in connection with the merger, costs to cancel contracts that will provide no future benefit to the combined company, occupancy costs related to lease cancellation penalties for space vacated in connection with the merger and investment banker and legal fees incurred in connection with the transaction. The $205.6 million pro forma adjustment is included in other liabilities and relates only to costs associated with AmSouth.
 
The pro forma financial statements also include an adjustment to establish a net deferred tax liability of $178.3 million which is based on 38% of all purchase accounting adjustments to assets and liabilities with the exception of excess purchase price. This deferred income tax adjustment is included in other liabilities.
 
In addition, the pro forma statement of financial condition includes an estimated $14.3 million adjustment to allowance for loan losses, which represents the estimated impact of Statement of Position 03-3, Accounting for Certain Loans or Debt Securities Acquired in a Transfer (“SOP 03-3”), on this transaction.
 
For purposes of this analysis, we have assumed that we will need to make divestitures of branches with aggregate deposits of approximately $2.5 billion, and related loans and securities, in order to obtain approval of the merger by the Federal Reserve Board. This assumption represents the high-end of our currently estimated range of $2.2 to $2.5 billion for divestitures; these estimates are preliminary and are based on Federal Reserve Board decisions in other cases and published deposit figures and, while we currently believe this estimate is reasonable, there can be no assurance that the final amount will not be different than this preliminary estimate. We have also assumed that these divestitures will be funded with approximately $850 million in loans and $1.275 billion in securities available for sale. These amounts are shown net of the expected 15% premium (or $375 million) on the deposits divested. These adjustments, as well as estimates of the foregone interest from these transactions, are included in the pro forma financial statements. The adjustments recorded for these divestitures on the merger date could vary significantly from the pro forma adjustments included herein depending on final regulatory divestiture requirements and changes in interest rates. The divestiture estimates are preliminary and are based on Federal Reserve Board decisions in other cases and published deposit figures and, while we currently believe this estimate is reasonable, there can be no assurance that the final amount will not be different than this preliminary estimate.

The pro forma condensed combined statements of income for the three months ended March 31, 2006 and for the year ended December 31, 2005 include adjustments for the amortization of the estimated core deposit intangible, the estimated accretion of the unrealized loss on AmSouth’s securities, the estimated amortization or accretion of purchase accounting adjustments made to loans, interest-bearing deposits, and long-term borrowings, and the related tax effect of all the adjustments. The amortization or accretion of the purchase accounting adjustments made to loans, interest-bearing deposits, and long-term borrowings, as well as the accretion of the unrealized loss on AmSouth’s securities, was estimated based on the weighted average maturities. Purchase accounting adjustments are also included to reflect the estimated foregone interest income from divested loans and securities available for sale and interest expense from divested deposits. An analysis to determine the purchase accounting adjustment to AmSouth’s property and equipment has not yet been completed. When this analysis is complete, adjustments to estimated depreciation expense will be included herein.
 
The estimated restructuring and merger related expenses discussed in Note 5 are not included in the pro forma statements of income since they will be recorded in the combined results of operations as they are incurred after completion of the merger and are not indicative of what the historical results of the combined company would have been had the companies been actually combined during the periods presented.
 
Additionally, Regions expects to realize approximately $400 million in cost savings following the merger, which Regions expects to be phased in over a two year period. These cost savings are not reflected in the pro forma financial information.

Note 5.
 
In connection with the merger, Regions and AmSouth have begun to further develop their preliminary plans to consolidate the operations of Regions and AmSouth. Over the next several months, the specific details of these plans will be refined. Regions and AmSouth are currently in the process of assessing the two companies’ personnel, benefit plans, premises, equipment, computer systems and service contracts to determine where we may take advantage of redundancies or where it will be beneficial or necessary to convert to one system. Certain decisions arising from these assessments may involve involuntary termination of AmSouth’s employees, vacating AmSouth’s leased premises, canceling contracts between AmSouth and certain service providers and selling or otherwise disposing of certain premises, furniture and equipment owned by AmSouth. The costs associated with such decisions will be recorded as purchase accounting adjustments, which have the effect of increasing the amount of the purchase price allocable to excess purchase price. It is expected that all such costs will be identified and recorded within one year of completion of the merger and all such actions required to effect these decisions would be taken within one year after finalization of these plans. The pro forma condensed combined consolidated statement of financial condition includes a preliminary estimate of such costs of $205.6 million, which represents liabilities assumed. See Note 3 for additional discussion.
 
In addition to decisions regarding AmSouth’s employees and activities, certain decisions may be made to involuntarily terminate Regions employees, vacate Regions leased premises, cancel contracts and sell or otherwise dispose of certain premises, furniture and equipment owned by Regions. These exit and disposal costs would be recorded in accordance with Financial Accounting Standards Board, or “FASB,” Statement No. 146, “Accounting for Costs Associated with Exit or Disposal Activities,” in the results of operations of the combined company in the period incurred. Regions also expects to incur merger-related expenses in the process of combining the operations of the two companies. These merger-related expenses include system conversion costs, employee retention arrangements and costs of incremental communications to customers and others. It is expected that the exit and disposal costs along with the merger-related costs will be incurred over a two year period after completion of the merger. Preliminarily, we estimate these restructuring and merger-related expenses will approximate $494.4 million. The $494.4 million estimate is not included in the pro forma statements of income since these costs will be recorded in the combined results of operations as they are incurred after completion of the merger and are not indicative of what the historical results of Regions would have been had Regions and AmSouth actually been combined during the periods presented.

COMPARISON OF STOCKHOLDERS’ RIGHTS
 
General
 
Regions and AmSouth are both incorporated under Delaware law. Any differences, therefore, in the rights of holders of Regions common stock and AmSouth common stock arise primarily from differences in their respective certificates of incorporation and bylaws. Upon completion of the merger, the certificate of incorporation and bylaws of Regions in effect immediately prior to the effective time of the merger will be the certificate of incorporation and bylaws of the combined company. Consequently, after the effective time of the merger, the rights of former AmSouth stockholders will be determined by reference to the Regions certificate of incorporation and bylaws. The material differences between the rights of holders of Regions common stock and AmSouth common stock (in the case of the bylaws, as amended as required under the merger agreement) resulting from the differences in their governing corporate instruments, are summarized below. This summary contains a list of the material differences but is not meant to be relied upon as an exhaustive list or a detailed description of the provisions discussed and is qualified in its entirety by reference to the Delaware General Corporation Law and the governing instruments of Regions and AmSouth, to which you are referred. The governing instruments are subject to amendment in accordance with their terms. Copies of the governing corporate instruments are available, without charge, to any person, including any beneficial owner to whom this document is delivered, by following the instructions listed under “Where You Can Find More Information.”
 
Authorized Capital
 
Regions
 
Regions’ certificate of incorporation authorizes 1.5 billion shares of Regions common stock, par value $0.01 per share, and 10 million shares of preferred stock, par value $1.00 per share. At [          ], 2006, [          ] shares of Regions common stock were issued and outstanding and no shares of preferred stock were issued and outstanding.
 
AmSouth
 
The authorized capital stock of AmSouth consists of 750 million shares of common stock, par value $1.00 per share, and 2 million shares of preferred stock, without par value. At [          ], 2006, [          ] shares of AmSouth common stock were issued and outstanding, and [          ] shares of AmSouth common stock were held in treasury. No shares of AmSouth preferred stock were issued and outstanding on [          ], 2006.
 
Number of Directors
 
Regions
 
Regions’ bylaws provide that the number of directors may be fixed by the board of directors, provided that the number of directors is not less than three directors. After the completion of the merger, the bylaws of Regions will provide that the board of directors will consist of twelve directors of Regions designated by Regions (plus up to one additional director to be added prior to the completion of the merger with the mutual agreement of Regions and AmSouth), and nine directors of AmSouth (plus up to one additional director to be added prior to the completion of the merger with the mutual agreement of Regions and AmSouth) designated by AmSouth.

Vacancies
 
Regions
 
Regions’ bylaws provide that vacancies on Regions’ board of directors may be filled only by Regions’ board of directors. After the completion of the merger and until the third anniversary of the completion of the merger, the bylaws of Regions will provide that all vacancies on the board of directors of Regions created by the cessation of service of a director who was a director of Regions prior to the completion of the merger will be filled by a nominee proposed to the nominating committee of the board of directors of Regions by a majority of the remaining directors who were directors of Regions prior to completion of the merger, and all vacancies on the board of directors of Regions created by the cessation of service of a former AmSouth director shall be filled by a nominee proposed to the nominating committee of the board of directors of Regions by a majority of the remaining former AmSouth directors.
 
AmSouth
 
AmSouth’s restated certificate of incorporation provides that vacancies on AmSouth’s board of directors may be filled by an affirmative vote by a majority of AmSouth’s remaining directors. If the number of directors remaining in office constitutes fewer than a quorum, the vacancy may be filled by a vote of the majority of those directors then in office.
 
Special Meetings of the Board
 
Regions
 
Special meetings of Regions’ board of directors may be called for any purpose or purposes, at any time, by the chief executive officer, the president, or the secretary on the written request of a majority of the board of directors.
 
AmSouth
 
Special meetings of AmSouth’s board of directors may be called for any purpose or purposes, at any time, by the chief executive officer or any three or more directors of AmSouth.
 
Stockholder Rights Plans
 
Regions
 
Regions does not have a stockholder rights plan.
 
AmSouth
 
On December 18, 1997, AmSouth adopted a stockholder protection rights agreement which attaches a right to every common share outstanding entitling its holder, upon the occurrence of certain events, to purchase from AmSouth one one-thousandth of a share of Series A Preferred Stock, without par value, for $88.89, subject to adjustment for certain events. The rights will be exercisable only if a person or group acquires 15% or more of AmSouth’s common stock or commences a tender offer that will result in such person or group owning 15% or more of AmSouth’s common stock. The rights may be redeemed by action of the Board for $.01 per right.
 
Classified Board of Directors and Cumulative Voting
 
Regions
 
Regions’ certificate of incorporation provides that the board of directors is divided into three classes, with each class to be as nearly equal in number as possible. The directors in each class serve three-year terms of office.
 
Stockholders are entitled to one vote for each share of Regions’ common stock, and directors are elected by a plurality of the votes cast by all stockholders under Regions’ certificate of incorporation. Stockholders are not entitled to cumulative voting rights in the election of directors.

Amendment of Certificate of Incorporation and Bylaws
 
Regions
 
Generally, the approval of the board of directors and the affirmative vote of a majority of all shares entitled to vote is required to amend Regions’ certificate of incorporation. Regions’ certificate of incorporation, however, requires the affirmative vote of at least 75% of the outstanding shares of Regions common stock in order to amend or repeal the provisions related to directors, business combinations with interested stockholders, the prohibition on action of stockholders by written consent and the amendment of the certificate of incorporation and bylaws.
 
Regions’ certificate of incorporation provides that the board of directors has the power to adopt, amend, or repeal the bylaws. However, after the completion of the merger, the affirmative vote of not less than 75% of the full board of directors will be required to amend the provisions described above in “The Merger — Board of Directors and Management of Regions Following the Merger.” Any action taken by the stockholders with respect to adopting, amending or repealing any bylaws may be taken only upon the affirmative vote of the holders of at least 75% of the outstanding shares of Regions common stock.

Table of Contents

AmSouth
 
Generally, the approval of the board of directors and the affirmative vote of a majority of all shares entitled to vote is required to amend AmSouth’s certificate of incorporation. AmSouth’s certificate of incorporation, however, requires the affirmative vote of the holders of at least 67 percent of the outstanding common stock to amend the provisions related to stockholder meetings. AmSouth’s certificate of incorporation also requires the affirmative vote of the holders of at least 80 percent of the outstanding common stock, and the affirmative vote of the holders of not less than 67 percent of the outstanding common stock not including a potential acquiror, to amend the provision relating to certain business combinations. AmSouth’s certificate of incorporation also requires the affirmative vote of the holders of at least 80 percent of the outstanding common stock to amend the provision relating to the classification and composition of its board of directors.
 
AmSouth’s board of directors may adopt, amend, or repeal AmSouth’s bylaws by a majority vote of the entire board of directors. Stockholder amendment of the bylaws requires a supermajority in the same circumstances described above with respect to the AmSouth certificate of incorporation.

Ernst & Young LLP, independent registered public accounting firm, has audited AmSouth’s consolidated financial statements included in AmSouth’s Annual Report on Form 10-K for the year ended December 31, 2005, and management’s assessment of the effectiveness of AmSouth’s internal control over financial reporting as of December 31, 2005, as set forth in their reports, which are incorporated by reference in this prospectus and elsewhere in the registration statement.

With respect to AmSouth’s unaudited consolidated interim financial information for the quarter ended March 31, 2006, which is incorporated by reference in this prospectus and elsewhere in the registration statement, Ernst & Young LLP reported that they have applied limited procedures in accordance with professional standards for a review of such information. However, their separate report dated May 5, 2006, included in AmSouth’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2006, and incorporated by reference herein, states that they did not audit and they do not express an opinion on that interim financial information. Accordingly, the degree of reliance on their report on such information should be restricted in light of the limited nature of the review procedures applied. Ernst & Young LLP is not subject to the liability provisions of Section 11 of the Securities Act of 1933 (the “Act”) for their report on the unaudited interim financial information because that report is not a “report” or a “part” of the Registration Statement prepared or certified by Ernst & Young LLP within the meaning of Sections 7 and 11 of the Act.
 
Regions expects representatives of Ernst & Young LLP to attend the Regions special meeting and AmSouth expects representatives of Ernst & Young LLP to attend the AmSouth special meeting. These representatives will have an opportunity to make a statement if they desire to do so, and we expect that they will be available to respond to any appropriate questions you may have.

RECITALS

C.  Intention of the Parties.   It is the intention of the Parties that, for federal income Tax purposes, the Merger shall qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code and that this Agreement shall constitute a “plan of reorganization” for purposes of Sections 354 and 361 of the Internal Revenue Code.
 
D.  Defined Terms.   Certain capitalized terms used in this Agreement are defined in 7.1 of this Agreement.
 
NOW, THEREFORE, in consideration of the above and the mutual warranties, representations, covenants, and agreements set forth herein, and intending to be legally bound hereby, the Parties agree as follows:
 
ARTICLE 1
 
THE MERGER
 
1.1  Merger.  Subject to the terms and conditions of this Agreement, at the Effective Time, AmSouth shall be merged with and into Regions in accordance with the provisions of Section 251 of the DGCL (the “Merger”). Regions shall be the surviving corporation in the Merger (the “Surviving Corporation”) and shall continue to be governed by the Laws of the State of Delaware. Upon consummation of the Merger, the separate corporate existence of AmSouth shall cease.
 
1.2  Time and Place of Closing.  The closing of the Merger (the “Closing”) shall take place at such time and place as Regions and AmSouth shall agree, on the date when the Effective Time (as defined in Section 1.3) is to occur (the “Closing Date”).
 
1.3  Effective Time.  Subject to the terms and conditions of this Agreement, on the Closing Date, the Parties will cause a certificate of merger to be filed with the Secretary of State of the State of Delaware (the “Delaware Secretary”) as provided in Section 251 of the DGCL to effect the Merger. The Merger shall take effect when such certificate of merger is filed, or at such other time as may be specified therein (the “Effective Time”). Subject to the terms and conditions hereof, unless otherwise mutually agreed upon by the duly authorized officers of each Party, the Parties shall cause the Effective Time to occur on the third business day following the date on which satisfaction or waiver of the last of the conditions set forth in Article 5 has occurred (other than those conditions that by their nature are to be satisfied at the Closing, but subject to the fulfillment or waiver of those conditions), or such earlier date mutually agreed upon by the Parties.
 
1.4  Conversion of AmSouth Common Stock.  At the Effective Time, in each case subject to Section 1.5, by virtue of the Merger and without any action on the part of the Parties or the holder of any securities of the parties:
 
(a) Each share of AmSouth Common Stock (including the AmSouth Stockholder Rights) that is Outstanding immediately prior to the Effective Time (other than shares of AmSouth Common Stock held


A-1


Table of Contents

by either Party (in each case other than in a fiduciary or agency capacity or on behalf of third parties or as a result of debts previously contracted)) shall be converted into 0.7974 fully paid and nonassessable shares of Regions Common Stock (the “Exchange Ratio”).
 
(b) All shares of AmSouth Common Stock (including the AmSouth Stockholder Rights) converted pursuant to this Section 1.4 shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist as of the Effective Time, and each certificate previously representing any such shares of AmSouth Common Stock (the “Old AmSouth Certificates”) shall cease to represent any rights except the right to receive with respect to each underlying share of AmSouth Common Stock (i) a certificate representing the number of whole shares of Regions Common Stock into which the shares of AmSouth Common Stock represented by such Old AmSouth Certificate have been converted pursuant to this Section 1.4, (ii) in accordance with Section 1.4(c), cash in lieu of fractional shares of Regions Common Stock represented by such Old AmSouth Certificate which have been converted pursuant to this Section 1.4; and (iii) any dividends or distributions which the holder thereof has the right to receive pursuant to Section 2.1(a).
 
(c) Notwithstanding any other provision of this Agreement, each holder of shares of AmSouth Common Stock exchanged pursuant to the Merger which would otherwise have been entitled to receive a fraction of a share of Regions Common Stock (after taking into account all Old AmSouth Certificates delivered by such holder) shall receive, in lieu thereof, cash (without interest and rounded to the nearest cent) in an amount equal to such fractional part of a share of Regions Common Stock multiplied by the closing sale price of Regions Common Stock on the NYSE Composite Transaction Tape on the trading day immediately preceding the Closing Date as reported by The Wall Street Journal or, if not reported therein, in another authoritative source .
 
(d) If, following the date of this Agreement and prior to the Effective Time, the outstanding shares of Regions Common Stock or AmSouth Common Stock shall have been increased, decreased, changed into or exchanged for a different number or kind of shares or securities as a result of a reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split, or other similar change in capitalization, then an appropriate and proportionate adjustment shall be made to the number of shares of Regions Common Stock that each share of AmSouth Common Stock shall represent the right to receive upon conversion.
 
1.5  Effects on Common Stock.
 
(a) At and after the Effective Time, each share of Regions Common Stock issued and outstanding immediately prior to the Effective Time shall remain an issued and outstanding share of common stock of the Surviving Corporation and shall not be affected by the Merger; provided that any shares of Regions Common Stock held by AmSouth or its Subsidiaries prior to the Effective Time (other than in a fiduciary or agency capacity or on behalf of third parties or as a result of debts previously contracted) shall be cancelled and retired and shall resume the status of authorized and unissued shares of Regions Common Stock, and no shares of Regions Common Stock or other securities of Regions shall be issued in respect thereof.
 
(b) Each of the shares of AmSouth Common Stock held by either Party (in each case other than in a fiduciary or agency capacity or on behalf of third parties as a result of debts previously contracted) shall be cancelled and retired and shall cease to exist at the Effective Time and no consideration shall be issued in exchange therefor.
 
1.6  AmSouth Stock Options and Other Equity-Based Awards.
 
(a) Each option to purchase shares of AmSouth Common Stock (an “AmSouth Stock Option”) granted under an equity or equity-based compensation plan of AmSouth (an “AmSouth Stock Plan”), whether vested or unvested, that is outstanding and unexercised immediately prior to the Effective Time shall cease, at the Effective Time, to represent a right to acquire shares of AmSouth Common Stock and shall be converted at the Effective Time, without any action on the part of any holder of any AmSouth Stock Option, into an option to purchase a share of Regions Common Stock (a “Regions Stock Option”) on the same terms and conditions as were applicable under such AmSouth Stock Option (but taking into account any changes thereto, including any acceleration thereof, provided for in the relevant AmSouth Stock Plan, or in the related award document by reason of the transactions contemplated hereby). The number of shares of Regions Common Stock subject to each such Regions Stock Option shall be equal to the number of shares of AmSouth Common Stock subject to each such AmSouth Stock Option multiplied by the Exchange Ratio, rounded, if necessary, to the nearest whole share of Regions Common


A-2


Table of Contents

Stock, and such Regions Stock Option shall have an exercise price per share (rounded to the nearest cent) equal to the per share exercise price specified in such AmSouth Stock Option divided by the Exchange Ratio; provided that, in the case of any AmSouth Stock Option to which Section 421 of the Internal Revenue Code applies as of the Effective Time (after taking into account the effect of any accelerated vesting thereof, if applicable) by reason of its qualification under Section 422 or Section 423 of the Internal Revenue Code, the exercise price, the number of shares of Regions Common Stock subject to such option and the terms and conditions of exercise of such option shall be determined in a manner consistent with the requirements of Section 424(a) of the Internal Revenue Code; provided, further, that, in the case of any AmSouth Stock Option to which Section 409A of the Internal Revenue Code applies as of the Effective Time, the exercise price, the number of shares of Regions Common Stock subject to such option and the terms and conditions of exercise of such option shall be determined in a manner consistent with the requirements of Section 409A of the Internal Revenue Code.
 
(b) At the Effective Time, each Right consisting of, based on or relating to shares of AmSouth Common Stock granted under an AmSouth Stock Plan, other than AmSouth Stock Options (each, an “AmSouth Stock-Based Award”), whether contingent or accrued, which is outstanding immediately prior to the Effective Time shall cease, at the Effective Time, to represent a Right with respect to shares of AmSouth Common Stock and shall be converted without any action on the part of any holder of a Right, at the Effective Time, into a Right consisting of, based on or relating to shares of Regions Common Stock granted under a Regions Stock Plan, other than Regions Stock Options (each, a “Regions Stock-Based Award”), on the same terms and conditions as were applicable under the AmSouth Stock-Based Awards (but taking into account any changes thereto, including any acceleration thereof, provided for in the relevant AmSouth Stock Plan or in the related award document by reason of the transactions contemplated hereby). The number of shares of Regions Common Stock subject to each such Regions Stock-Based Award shall be equal to the number of shares of AmSouth Common Stock subject to the AmSouth Stock-Based Award multiplied by the Exchange Ratio, rounded, if necessary, to the nearest whole share of Regions Common Stock and, if applicable, such Regions Stock-Based Award shall have an exercise price per share (rounded to the nearest cent) equal to the per share exercise price specified in the AmSouth Stock-Based Award divided by the Exchange Ratio. Any dividend equivalents credited to the account of each holder of an AmSouth Stock-Based Award as of the Effective Time shall remain credited to such holder’s account immediately following the Effective Time, subject to adjustment in accordance with the foregoing.
 
(c) As soon as practicable after the Effective Time, Regions shall deliver to the holders of AmSouth Stock Options and AmSouth Stock-Based Awards any required notices setting forth such holders’ rights pursuant to the relevant AmSouth Stock Plans and award documents and stating that such AmSouth Stock Options and AmSouth Stock-Based Awards have been assumed by Regions and shall continue in effect on the same terms and conditions (subject to the adjustments required by this Section 1.6 after giving effect to the Merger and the terms of the relevant AmSouth Stock Plans).
 
(d) Following the Effective Time, Regions may maintain the AmSouth Stock Plans for purposes of granting future awards in accordance with the NYSE rules.

EXCHANGE OF SHARES
 
2.1  Exchange Procedures.
 
(a) At or prior to the Effective Time, Regions shall deposit, or shall cause to be deposited, with the Exchange Agent, for the benefit of the holders of Old AmSouth Certificates, for exchange in accordance with Article 1 and this Article 2, certificates representing Regions Common Stock (“New Certificates”) (together with any dividends or distributions with respect thereto and any cash to be paid hereunder in lieu of fractional shares of Regions Common Stock (without any interest thereon), the “Exchange Fund”) to be paid pursuant to Article 1 and this Article 2 in exchange for outstanding shares of AmSouth Common Stock.
 
(b) As promptly as practicable after the Effective Time, Regions shall send or cause to be sent to each former holder of record of shares of AmSouth Common Stock immediately prior to the Effective Time (each, a “Holder”), transmittal materials for use in exchanging such Holder’s Old AmSouth Certificates for the consideration set forth in Article 1 (which shall specify that delivery shall be effected, and risk of loss and title to the certificates theretofore representing such shares of AmSouth Common Stock shall pass, only upon proper delivery of such certificates to the Exchange Agent). Regions shall cause the New Certificates for shares of Regions Common Stock into which shares of a Holder’s AmSouth Common Stock are converted at the Effective Time or dividends or distributions which such Person shall be entitled to receive and any fractional share interests to be delivered to such Person upon delivery to the Exchange Agent of Old AmSouth Certificates representing such shares of AmSouth Common Stock, together with the transmittal materials, duly executed and completed in accordance with the instructions thereto. No interest will accrue or be paid on any such cash to be paid pursuant to Article 1 and this Article 2 upon such delivery. If any New Certificate is to be issued or any cash payment is to be made in a name other than that in which the Old AmSouth Certificate surrendered in exchange therefor is registered, it shall be a condition of such exchange that the Person requesting such exchange shall pay any transfer or other Taxes required by reason of the issuance of such New Certificate or the making of such cash payment in a name other than that of the registered Holder of the Old AmSouth Certificate surrendered, or shall establish to the satisfaction of Regions and the Exchange Agent that any such Taxes have been paid or are not applicable. Any Person who the Parties reasonably believe to be an “affiliate”

of AmSouth for purposes of Rule 145 of the 1933 Act shall not be entitled to receive any New Certificate or payment pursuant to Article 1 or this Article 2 until such Person shall have duly executed and delivered an appropriate agreement as described in Section 4.14.
 
(c) Notwithstanding the foregoing, none of the Exchange Agent, any of the Parties or any of their respective Subsidiaries shall be liable to any former Holder for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar Laws.
 
(d) If any Old AmSouth Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Old AmSouth Certificate to be lost, stolen or destroyed and, if required by Regions or the Exchange Agent, the posting by such Person of a bond in such reasonable amount as Regions or the Exchange Agent may direct as indemnity against any claim that may be made against it with respect to such Old AmSouth Certificate, Regions or the Exchange Agent shall, in exchange for the shares of AmSouth Common Stock represented by such lost, stolen or destroyed Old AmSouth Certificate, issue or cause to be issued a New Certificate and pay or cause to be paid the amounts, if any, deliverable in respect to the shares of AmSouth Common Stock formerly represented by such Old AmSouth Certificate pursuant to this Agreement.
 
(e) Any portion of the Exchange Fund that remains unclaimed by the Holders of AmSouth Common Stock for six months after the Effective Time shall be returned to Regions (together with any dividends or earnings in respect thereof). Any Holders of AmSouth Common Stock who have not theretofore complied with this Article 2 shall thereafter be entitled to look only to Regions, and only as a general creditor thereof, for payment of the consideration deliverable in respect of each share of AmSouth Common Stock such Holder holds as determined pursuant to this Agreement, without any interest thereon.
 
(f) The Exchange Agent and Regions shall be entitled to deduct and withhold from any cash in lieu of fractional shares of Regions Common Stock, cash dividends or distributions payable pursuant to Section 2.1(a) and any other cash amounts otherwise payable pursuant to this Agreement to any Holder such amounts as the Exchange Agent or Regions, as the case may be, is required to deduct and withhold under the Internal Revenue Code, or any provision of state, local or foreign Tax law, with respect to the making of such payment. To the extent the amounts are so withheld by the Exchange Agent or Regions, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Holder in respect of whom such deduction and withholding was made by the Exchange Agent or Regions, as the case may be.
 
2.2  Rights of Holders.  At the Effective Time, the stock transfer books of AmSouth shall be closed and no transfer by any Holder shall thereafter be made or recognized. Until surrendered for exchange in accordance with the provisions of Section 2.1 and except as provided in this Section 2.2, each Old AmSouth Certificate (other than shares to be cancelled pursuant to Section 2.1(b)) shall, from and after the Effective Time, represent for all purposes only the right to receive the consideration provided in Section 1.4, as the case may be, and any dividends or any other distributions with a record date prior to the Effective Time which have been declared or made by AmSouth in respect of such shares of AmSouth Common Stock in accordance with the terms of this Agreement and which remain unpaid at the Effective Time. To the extent permitted by Law, Holders shall be entitled to vote after the Effective Time at any meeting of Regions stockholders the number of whole shares of Regions Common Stock into which their respective shares of AmSouth Common Stock are converted, regardless of whether such Holders have exchanged their certificates representing AmSouth Common Stock for New Certificates representing Regions Common Stock in accordance with the provisions of this Agreement, but beginning 60 days after the Effective Time no such Holder shall be entitled to vote on any matter until such Holder surrenders such Old AmSouth Certificate for exchange as provided in Section 2.1. Whenever a dividend or other distribution is declared by Regions on Regions Common Stock, the record date for which is at or after the Effective Time, the declaration shall include dividends or other distributions on all shares of Regions Common Stock issuable pursuant to this Agreement, but beginning 60 days after the Effective Time no dividend or other distribution payable to the holders of record of Regions Common Stock as of any time subsequent to the Effective Time shall be delivered to the Holder of an Old AmSouth Certificate until such Holder surrenders such Old AmSouth Certificate for exchange as provided in Section 2.1. However, upon surrender of the Old AmSouth Certificate, both the New Certificate, together with all such undelivered dividends or other distributions (without interest) and any undelivered cash payments to be paid

(i) It has disclosed in Section 3.3(k) of its Disclosure Letter, and has delivered or made available to the other Party prior to the date of this Agreement correct and complete copies of, all of its Compensation and Benefit Plans. Neither it nor any of its Subsidiaries has an “obligation to contribute” (as defined in ERISA Section 4212) nor have they ever had an obligation to contribute to a “multiemployer plan” (as defined in ERISA Sections 4001(a)(3) and 3(37)(A)). Each “employee pension benefit plan,” as defined in Section 3(2) of ERISA, that was ever maintained by it or any of its Subsidiaries and that was intended to qualify under Section 401(a) of the Internal Revenue Code, is disclosed as such in Section 3.3(k) of its Disclosure Letter.
 
(ii) It has delivered or made available to the other Party prior to the date of this Agreement correct and complete copies of the following applicable documents: (A) all trust agreements or other funding arrangements for its Compensation and Benefit Plans (including insurance Contracts), and all amendments thereto (all such trust agreements and other funding arrangements are disclosed in Section 3.3(k) of its Disclosure Letter), (B) with respect to any such Compensation and Benefit Plans or amendments, the most recent determination letters, and all material rulings, material opinion letters, material information letters, or material advisory opinions issued by the Internal Revenue Service, the United States Department of Labor, or the PBGC after December 31, 1994, (C) annual reports or returns, audited or unaudited financial statements, actuarial valuations and reports, and summary annual reports prepared for any Compensation and Benefit Plans with respect to the most recent plan year, and (D) the most recent summary plan descriptions and any material modifications thereto.

Except as

Table of Contents

disclosed in Section 3.3(k) of its Disclosure Letter, each trust created under any of its ERISA Plans has been determined to be exempt from Tax under Section 501(a) of the Internal Revenue Code and it is not aware of any circumstance which will or could reasonably result in revocation of such exemption. Any voluntary employees’ beneficiary association within the meaning of Section 501(c)(9) of the Internal Revenue Code which provides benefits under a Compensation and Benefit Plan has (i) received an opinion letter from the Internal Revenue Service recognizing its exempt status under Section 501(c)(9) of the Internal Revenue Code and (ii) filed a timely notice with the Internal Revenue Service pursuant to Section 505(c) of the Internal Revenue Code, and it is not aware of circumstances likely to result in the loss of such exempt status under Section 501(c)(9) of the Internal Revenue Code. There is no pending or, to its knowledge, threatened Litigation relating to any of its ERISA Plans.
 
(iv) Neither it nor any of its Subsidiaries has engaged in a transaction with respect to any of its Compensation and Benefit Plans that, assuming the Taxable Period of such transaction expired as of the date of this Agreement or the Effective Time, would subject it or any of its Subsidiaries to a Tax or penalty imposed by either Section 4975 of the Internal Revenue Code or Section 502(i) of ERISA.
 
(v) Except as disclosed in Section 3.3(k) of its Disclosure Letter, each of its Pension Plans had, as of the date of its most recent actuarial valuation, assets measured at fair market value at least equal to its “current liability,” as that term is defined in Section 302(d)(7) of ERISA. To its knowledge, since the date of the most recent actuarial valuation, no event has occurred which would adversely change any such funded status. None of its Pension Plans nor any “single-employer plan,” within the meaning of Section 4001(a)(15) of ERISA, currently maintained by it or any of its Subsidiaries, or the single-employer plan of any entity which is considered one employer with it under Section 4001 of ERISA or Section 414 of the Internal Revenue Code (an “ERISA Affiliate”) has an “accumulated funding deficiency” within the meaning of Section 412 of the Internal Revenue Code or Section 302 of ERISA (whether or not waived). All required contributions with respect to any of its Pension Plans or any single-employer plan of any of its ERISA Affiliates have been timely made and there is no lien, nor is there expected to be a lien, under Internal Revenue Code Section 412(n) or ERISA Section 302(f) or Tax under Internal Revenue Code Section 4971. Neither it nor any of its Subsidiaries has provided, or is required to provide, security to any of its Pension Plans or to any single-employer plan of any of its ERISA Affiliates pursuant to Section 401(a)(29) of the Internal Revenue Code.
 
(vi) No Liability under Title IV of ERISA has been or is expected to be incurred by it or any of its Subsidiaries with respect to any defined benefit plan currently or formerly maintained by any of them or by any of its ERISA Affiliates that has not been satisfied in full (other than Liability for PBGC premiums, which have been paid when due).
 
(vii) Except as disclosed in Section 3.3(k) of its Disclosure Letter, neither it nor any of its Subsidiaries has any obligations for retiree health and retiree life benefits under any of its Compensation and Benefit Plans other than with respect to benefit coverage mandated by applicable Law. It or its subsidiaries may amend or terminate any such plan at any time without incurring any liability thereunder other than in respect of claims incurred prior to such amendment or termination.
 
(viii) There has been no amendment to, announcement by it or any of its Subsidiaries relating to, or change in employee participation or coverage under, any Compensation and Benefit Plan which would increase the expense of maintaining such plan above the level of the expense incurred therefor for the most recent fiscal year. None of the execution and delivery of this Agreement or the Option Agreements, the stockholder approval of the transactions contemplated hereby or the consummation of the transactions contemplated hereby or thereby (A) results in any payment or increase in payment (including severance, golden parachute, or otherwise), whether or not in conjunction with a termination of employment, becoming due to any director or any employee of it or any of its Subsidiaries from it or any of its Subsidiaries under any of its Compensation and Benefit Plans or otherwise, (B) increases any benefits otherwise payable under any of its Compensation and Benefit Plans, (C) results in any acceleration of the time of payment or vesting or result in any payment or funding (through a grantor trust or otherwise) of any such payment or benefit, (D) limits or restrict the right of it to merge, amend or terminate any of the Compensation and Benefit Plans or (E) results in

Neither it nor any of its Subsidiaries, nor to its knowledge, any other party thereto, is in Default of any of its obligations under any such agreement or arrangement.

4.9  Investigation and Confidentiality.
 
(a) Each Party shall permit the other Party to make or cause to be made such investigation of the business and Properties of it and its Subsidiaries and of their respective financial and legal conditions as the other Party reasonably requests; provided, that such investigation shall be reasonably related to the transactions contemplated hereby and shall not interfere unnecessarily with normal operations; and provided further, that neither Party nor any of their respective Subsidiaries shall be required to provide access to or to disclose information where such access or disclosure would jeopardize the attorney-client or other privilege with respect to such information or contravene any Law, Order, or Contract and the Parties will use their reasonable efforts to make appropriate substitute disclosure arrangements, to the extent practicable, in circumstances in which the restrictions of this proviso apply. No investigation by a Party shall affect the representations and warranties of the other Party.
 
(b) Each Party shall, and shall cause its Representatives to, maintain the confidentiality of all confidential information or Evaluation Material furnished to it by the other Party concerning its and its Subsidiaries’ businesses, operations, and financial positions to the extent required by, and in accordance with the Confidentiality Agreement, and shall not use such information for any purpose except in furtherance of the transactions contemplated by this Agreement. If this Agreement is terminated prior to the Effective Time, each Party shall promptly return or certify the destruction of all documents and copies and extracts thereof, and all work papers containing confidential information received from the other Party.
 
4.10  Press Releases; Publicity.  Prior to the Effective Time, the Parties shall consult with each other as to the form and substance of any press release or other public statement materially related to this Agreement and the transactions contemplated hereby prior to issuing such press release or public statement or making any other public disclosure related thereto (including any broad-based employee communication that is reasonably likely to become the subject of public disclosure); provided, that nothing in this Section 4.10 shall be deemed to prohibit any Party from making any disclosure necessary in order to satisfy such Party’s disclosure obligations imposed by Law or the NYSE or any other self-regulatory organization.
 
4.11  Acquisition Proposals.
 
(a) Each Party agrees that it will not, and will cause its Subsidiaries and its and its Subsidiaries’ officers, directors, Representatives and Affiliates not to, directly or indirectly, (i) initiate, solicit, encourage or knowingly facilitate inquiries or proposals with respect to, (ii) engage or participate in any negotiations concerning, or (iii) provide any confidential or nonpublic information or data to, or have, or engage or participate in, any discussions with, any Person relating to, any Acquisition Proposal; provided that, in the event either Party receives an unsolicited bona fide written Acquisition Proposal with respect to such Party, such Party may, and may permit its Subsidiaries and its and its Subsidiaries’ Representatives to, furnish or cause to be furnished nonpublic information or data and participate in such negotiations or discussions to the extent that the Board of Directors of such Party concludes in good faith (after receiving the advice of its outside counsel and its financial advisors) that failure to take such actions would result in a violation of its fiduciary duties under applicable Law; provided further that, prior to providing any nonpublic information permitted to be provided pursuant to the foregoing proviso, it shall have entered into a confidentiality agreement with such third party on terms no less favorable to it than those of the Confidentiality Agreement. Each Party will immediately cease and cause to be terminated any activities, discussions or negotiations conducted before the date of this Agreement with any Persons other than AmSouth or Regions, as the case dictates, with respect to any Acquisition Proposal. Each Party will promptly (within one day) advise the other Party following receipt of any Acquisition Proposal or any inquiry which could reasonably be expected to lead to an Acquisition Proposal, and the substance thereof (including the identity of the Person making such Acquisition Proposal), and will keep the other Party apprised of any related developments, discussions and negotiations on a current basis.

4.12  Takeover Laws; No Rights Triggered.  If any Takeover Law may become, or may purport to be, applicable to the transactions contemplated hereby or by the Option Agreements, each Party and the members of their respective Boards of Directors will grant such approvals and take such actions as are necessary (other than any action requiring the approval of its stockholders (other than as contemplated by Section 4.5)) so that the transactions contemplated by this Agreement and by the Option Agreements may be consummated as promptly as practicable on the terms contemplated hereby and thereby and otherwise act to eliminate or minimize the effects of any Takeover Law on any of the transactions contemplated by this Agreement or by the Option Agreements. AmSouth shall take all action necessary to ensure that, so long as this Agreement shall not have been terminated pursuant to the terms hereof, that no Person shall become able to exercise any rights under the AmSouth Rights Plan or enable or require the AmSouth Shareholder Rights to separate from the shares of AmSouth Common Stock to which they are attached or to be triggered or become exercisable or unredeemable as a result of entering into this Agreement or consummating the transactions contemplated hereby. The Parties agree that none of AmSouth’s representations, warranties, covenants or agreements set forth in this Agreement shall be deemed to be inaccurate, untrue or breached in any respect for any purpose as a result of the redemption of the AmSouth Shareholder Rights with the prior written consent of Regions.
 
4.13  Exemption from Liability Under Section 16(b).  Regions and AmSouth agree that, in order to most effectively compensate and retain AmSouth Insiders (as defined below) in connection with the Merger, both prior to and after the Effective Time, it is desirable that AmSouth Insiders not be subject to a risk of liability under Section 16(b) of the 1934 Act to the fullest extent permitted by applicable Law in connection with the conversion of shares of AmSouth Common Stock into shares of Regions Common Stock in the Merger and the conversion of AmSouth Stock Options and AmSouth Stock-Based Awards into Regions Stock Options or Regions Stock-Based Awards in the Merger, and for that compensatory and retentive purposes agree to the provisions of this Section 4.13. Assuming AmSouth delivers to Regions in a reasonably timely fashion prior to the Effective Time accurate information regarding those officers and directors of AmSouth subject to the reporting requirements of Section 16(a) of the 1934 Act (the “AmSouth Insiders”), the number of shares of AmSouth Common Stock to be held by each such AmSouth Insider expected to be exchanged for Regions Common Stock in the Merger, and the number and description of AmSouth Stock Options and AmSouth Stock-Based Awards held by each such AmSouth Insider and expected to be converted into Regions Stock Options or Regions Stock-Based Awards, the Board of Directors of Regions, or a committee of non-employee directors thereof (as such term is defined for purposes of Rule 16b-3(d) under the 1934 Act), shall reasonably promptly thereafter, and in any event prior to the Effective Time, adopt a resolution providing in substance that the receipt by the AmSouth Insiders of Regions Common Stock in exchange for shares of AmSouth Common Stock, and of Regions Stock Options upon conversion of AmSouth Stock Options, or Regions Stock-Based Awards upon conversion of AmSouth Stock-Based Awards, in each case pursuant to the transactions contemplated by this Agreement, are approved by such Board of Directors or by such committee thereof, and are intended to be exempt from Liability pursuant to Section 16(b) of the 1934 Act to the fullest extent permitted by applicable Law.
 
4.14  Agreement of Affiliates.  AmSouth shall use its reasonable efforts to cause each Person whom it reasonably believes may be deemed an “affiliate” of AmSouth, for purposes of Rule 145 under the 1933 Act, to deliver to Regions not later than the Effective Time, a written agreement in substantially the form of Exhibit 2.
 
4.15  Employee Benefits and Contracts.
 
(a) Following the Effective Time, Regions at its election shall either (i) provide generally to officers and employees of AmSouth and its Subsidiaries, who at or after the Effective Time become employees of Regions or its Subsidiaries (“AmSouth Continuing Employees”), employee benefits under Compensation and Benefit Plans maintained by Regions, on terms and conditions which are the same as for similarly situated officers and employees of Regions and its Subsidiaries, or (ii) maintain for the benefit of the AmSouth Continuing Employees, the Compensation and Benefit Plans maintained by AmSouth immediately prior to the Effective Time; provided that Regions may amend any Compensation and Benefit Plan maintained by AmSouth immediately prior to the Effective Time to comply with any Law or as necessary and appropriate for other business reasons. For purposes of this Section 4.15, Compensation and Benefit Plans maintained by Regions or AmSouth are deemed to include Compensation and Benefit Plans maintained by their respective Subsidiaries. As soon as practicable following the Effective Time, Regions and AmSouth shall cooperate in reviewing, evaluating and analyzing the Regions

Table of Contents

Compensation and Benefit Plans and the AmSouth Compensation and Benefit Plans with a view towards developing appropriate and effective Compensation and Benefit Plans for employees of Regions and AmSouth and their Subsidiaries after the Effective Time.
 
(b) For purposes of participation, vesting and benefit accrual (except not for purposes of benefit accrual with respect to any plan in which such credit would result in a duplication of benefits) under Regions’s Compensation and Benefit Plans, service with or credited by AmSouth or any of its Subsidiaries shall be treated as service with Regions; provided that this provision shall not cause Regions’s tax-qualified defined benefit pension plan (which is not open to new participants) to be opened to new participants. To the extent permitted under applicable Law, Regions shall cause welfare Compensation and Benefit Plans maintained by Regions that cover the AmSouth Continuing Employees after the Effective Time to (i) waive any waiting period and restrictions and limitations for preexisting conditions or insurability (except for pre-existing conditions that were excluded, or restrictions or limitations that were applicable, under welfare Compensation and Benefit Plans maintained by AmSouth), and (ii) cause any deductible, co-insurance, or maximum out-of-pocket payments made by the AmSouth Continuing Employees under welfare Compensation and Benefit Plans maintained by AmSouth to be credited to such Continuing Employees under welfare Compensation and Benefit Plans maintained by Regions, so as to reduce the amount of any deductible, co-insurance, or maximum out-of-pocket payments payable by such AmSouth Continuing Employees under welfare Compensation and Benefit Plans maintained by Regions.
 
(c) Nothing in this Section 4.15 shall be interpreted as preventing Regions, from and after the Effective Time, from amending, modifying or terminating any Compensation and Benefit Plans maintained by Regions, Compensation and Benefit Plans maintained by AmSouth, or other Contracts, arrangements, commitments or understandings, in accordance with their terms and applicable Law.
 
4.16  Indemnification.
 
(a) From and after the Effective Time, in the event of any threatened or actual claim, action, suit, proceeding, or investigation, whether civil, criminal, or administrative, in which any Person who is now, or has been at any time prior to the date of this Agreement, or who becomes prior to the Effective Time, a director or officer of AmSouth or any of its Subsidiaries (the “Indemnified Parties”) is, or is threatened to be, made a party based in whole or in part on, or arising in whole or in part out of, or pertaining to (i) the fact that he is or was a director, officer, or employee of AmSouth, any of its Subsidiaries, or any of its predecessors, or (ii) this Agreement, the Option Agreements or any of the transactions contemplated hereby or thereby, whether in any case asserted or arising before or after the Effective Time, Regions shall indemnify and hold harmless, to the fullest extent permitted by applicable Law each such Indemnified Party against any Liability (including advancement of reasonable attorneys’ fees and expenses prior to the final disposition of any claim, suit, proceeding, or investigation to each Indemnified Party to the fullest extent permitted by Law upon receipt of any undertaking required by applicable Law), judgments, fines, and amounts paid in settlement in connection with any such threatened or actual claim, action, suit, proceeding, or investigation.
 
(b) Regions agrees that all rights to indemnification and all limitations on Liability existing in favor of the directors, officers, and employees of AmSouth and its Subsidiaries (the “Covered Parties”) as provided in their respective Organizational Documents as in effect as of the date of this Agreement or in any indemnification agreement in existence on the date of this Agreement with AmSouth or its Subsidiaries and disclosed in AmSouth’s Disclosure Letter with respect to matters occurring prior to the Effective Time shall survive the Merger and shall continue in full force and effect, and shall be honored by such entities or their respective successors as if they were the indemnifying party thereunder, without any amendment thereto; provided, that nothing contained in this Section 4.16(b) shall be deemed to preclude any liquidation, consolidation, or merger after the Effective Time of any AmSouth Subsidiaries, in which case all of such rights to indemnification and limitations on Liability shall be deemed to so survive and continue notwithstanding any such liquidation, consolidation, or merger. Without limiting the foregoing, in any case in which approval by Regions is required to effectuate any indemnification, Regions shall direct, at the election of the Indemnified Party, that the determination of any such approval shall be made by independent counsel mutually agreed upon between Regions and the Indemnified Party.
 
(c) Regions, from and after the Effective Time, will directly or indirectly cause the Persons who served as directors or officers of AmSouth immediately prior to the Effective Time to be covered by Regions’s existing directors’ and officers’ liability insurance policy with respect to acts or omissions occurring prior to the Effective


A-21

Time which were committed by such officers and directors in their capacity as such; provided, that (i) Regions may substitute therefor policies of at least the same coverage and amounts containing terms and conditions which are not less advantageous than such policy, (ii) in no event shall Regions be required to expend more than 250% per year of coverage of the amount currently expended by AmSouth per year of coverage as of the date of this Agreement (the “Maximum Amount”) to maintain or procure insurance coverage pursuant hereto, and (iii) if notwithstanding the use of reasonable best efforts to do so, Regions is unable to maintain or obtain the insurance called for by this Section 4.16(c), Regions shall obtain as much comparable insurance as available for the Maximum Amount. Such insurance coverage shall commence at the Effective Time and will be provided for a period of no less than six years after the Effective Time.
 
(d) Any Indemnified Party wishing to claim indemnification under Section 4.16(a), upon learning of any claim, action, suit, proceeding or investigation described above, shall promptly notify Regions thereof; provided that the failure so to notify shall not affect the obligations of Regions under Section 4.16(a) unless and to the extent that Regions is prejudiced as a result of such failure.
 
(e) The provisions of this Section 4.16 are intended to be for the benefit of and shall be enforceable by, each Indemnified Party and his or her heirs and representatives.
 
4.17  Corporate Governance.
 
(a) Immediately prior to the execution and delivery of this Agreement, the Board of Directors of Regions adopted a resolution (not to be withdrawn) providing for the amendment of the Regions Bylaws, effective as of the Effective Time, to insert an Article IV, Section 11 as set forth below, which Article IV, Section 11 shall fully replace and supersede the Article III, Section 10 and Article IV, Section 11 in effect as of immediately before such amendment.

STOCK OPTION AGREEMENT (this “Agreement”), dated May 24, 2006, between AmSouth Bancorporation, a Delaware corporation (“Issuer”), and Regions Financial Corporation, a Delaware corporation (“Grantee”).
 
W I T N E S S E T H:
 
WHEREAS, Grantee and Issuer have entered into an Agreement and Plan of Merger of even date herewith (the “Merger Agreement”), which agreement has been executed and delivered by the parties hereto simultaneously with this Agreement;
 
WHEREAS, as a condition to Grantee’s entering into the Merger Agreement and in consideration therefor, Issuer has agreed to grant Grantee the Option (as hereinafter defined); and
 
WHEREAS, in connection with entering into the Merger Agreement, the Grantee has issued the Issuer an option (the “Reciprocal Option”) pursuant to a Stock Option Agreement in the form attached to the Merger Agreement.
 
NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements set forth herein and in the Merger Agreement, the parties hereto agree as follows:
 
1.  (a)  Issuer hereby grants to Grantee an unconditional, irrevocable option (the “Option”) to purchase, subject to the terms hereof, up to 69,027,842 fully paid and nonassessable shares of Issuer’s Common Stock, par value $1.00 per share (“Common Stock”), at a price of the lesser (i) $28.90 per share and (ii) the closing sale price of the Common Stock on the NYSE Composite Transaction Tape on the trading day immediately preceding the exercise date as reported by The Wall Street Journal or, if not reported therein, in another authoritative source (the “Option Price”); provided, however, that in no event shall the number of shares of Common Stock for which this Option is exercisable exceed 19.9% of the Issuer’s issued and outstanding shares of Common Stock without giving effect to any shares subject to or issued pursuant to the Option. The number of shares of Common Stock that may be received upon the exercise of the Option and the Option Price are subject to adjustment as herein set forth. If Issuer adopts a shareholder protection rights plan or similar agreement, Issuer shall make proper provision so that each share of Common Stock issued upon exercise of the Option shall be accompanied by the applicable number of rights under such agreement.
 
(b)  In the event that any additional shares of Common Stock are either (i) issued or otherwise become outstanding after the date of this Agreement (other than pursuant to this Agreement) or (ii) redeemed, repurchased, retired or otherwise cease to be outstanding after the date of this Agreement, the number of shares of Common Stock subject to the Option shall be increased or decreased, as appropriate, so that, after such issuance, such number equals 19.9% of the number of shares of Common Stock then issued and outstanding without giving effect to any shares subject or issued pursuant to the Option. Nothing contained in this Section 1(b) or elsewhere in this Agreement shall be deemed to authorize Issuer or Grantee to breach any provision of the Merger Agreement.
 
2.  (a)  The Holder (as hereinafter defined) may exercise the Option, in whole or part, and from time to time, if, but only if, both an Initial Triggering Event (as hereinafter defined) and a Subsequent Triggering Event (as hereinafter defined) shall have occurred prior to the occurrence of an Exercise Termination Event (as hereinafter defined), provided that the Holder shall have sent the written notice of such exercise (as provided in subsection (g) of this Section 2) within 180 days following such Subsequent Triggering Event.

(f) Issuer shall notify Grantee promptly in writing of the occurrence of any Initial Triggering Event or Subsequent Triggering Event of which it has knowledge, it being understood that the giving of such notice by Issuer shall not be a condition to the right of the Holder to exercise the Option.
 
(g) In the event the Holder is entitled to and wishes to exercise the Option, it shall send to Issuer a written notice (the date of which being herein referred to as the “Notice Date”) specifying (i) the total number of shares it will purchase pursuant to such exercise and (ii) a place and date not earlier than three business days nor later than 60 business days from the Notice Date for the closing of such purchase (the “Closing Date”); provided that if prior notification to or approval of the Federal Reserve Board or any other regulatory agency is required in connection with such purchase, the Holder shall as soon as reasonably practicable file the required notice or application for approval and shall expeditiously process the same, and the period of time that otherwise would run pursuant to this sentence shall run instead from the date on which any required notification periods have expired or been terminated or such approvals have been obtained and any requisite waiting period or periods shall have passed. Any exercise of the Option shall be deemed to occur on the Notice Date relating thereto.
 
(h) At the closing referred to in subsection (g) of this Section 2, the Holder shall pay to Issuer the aggregate purchase price for the shares of Common Stock purchased pursuant to the exercise of the Option in immediately available funds by wire transfer to a bank account designated by Issuer, provided that failure or refusal of Issuer to designate such a bank account shall not preclude the Holder from exercising the Option.
 
(i) At such closing, simultaneously with the delivery of immediately available funds as provided in subsection (h) of this Section 2, Issuer shall deliver to the Holder a certificate or certificates representing the number of shares of Common Stock purchased by the Holder and, if the Option should be exercised in part only, a new Option evidencing the rights of the Holder thereof to purchase the balance of the shares purchasable hereunder, and the Holder shall deliver to Issuer this Agreement and a letter agreeing that the Holder will not offer to sell or otherwise dispose of such shares in violation of applicable law or the provisions of this Agreement.

A copy of such agreement is on file at the principal office of Issuer and will be provided to the holder hereof without charge upon receipt by Issuer of a written request therefor.”
 
It is understood and agreed that: (i) the reference to the resale restrictions of the Securities Act of 1933, as amended (the “1933 Act”), in the above legend shall be removed by delivery of substitute certificate(s) without such reference if the Holder shall have delivered to Issuer a copy of a letter from the staff of the SEC, or an opinion of counsel, in form and substance reasonably satisfactory to Issuer, to the effect that such legend is not required for purposes of the 1933 Act; (ii) the reference to the provisions of this Agreement in the above legend shall be removed by delivery of substitute certificate(s) without such reference if the shares have been sold or transferred in compliance with the provisions of this Agreement and under circumstances that do not require the retention of such reference; and (iii) the legend shall be removed in its entirety if the conditions in the preceding clauses (i) and (ii) are both satisfied. In addition, such certificates shall bear any other legend as may be required by law.

(k) Upon the giving by the Holder to Issuer of the written notice of exercise of the Option provided for under subsection (g) of this Section 2 and the tender of the applicable purchase price in immediately available funds, the Holder shall be deemed to be the holder of record of the shares of Common Stock issuable upon such exercise, notwithstanding that the stock transfer books of Issuer shall then be closed or that certificates representing such shares of Common Stock shall not then be actually delivered to the Holder. Issuer shall pay all expenses, and any and all United States federal, state and local taxes and other charges that may be payable in connection with the preparation, issuance and delivery of stock certificates under this Section 2 in the name of the Holder or its assignee, transferee or designee.
 
3.  Issuer agrees: (i) that it shall at all times maintain, free from preemptive rights, sufficient authorized but unissued shares of Common Stock so that the Option may be exercised without additional authorization of Common Stock after giving effect to all other options, warrants, convertible securities and other rights to purchase Common Stock; (ii) that it will not, by charter amendment or through reorganization, consolidation, merger, dissolution or sale of assets, or by any other voluntary act, avoid or seek to avoid the observance or performance of any of the covenants, stipulations or conditions to be observed or performed hereunder by Issuer; (iii) promptly to take all action as may from time to time be required (including (x) complying with all premerger notification, reporting and waiting period requirements specified in 15 U.S.C. § 18a and regulations promulgated thereunder and (y) in the event, under the Bank Holding Company Act of 1956, as amended (the “BHCA”), or the Change in Bank Control Act of 1978, as amended, or any state banking law, prior approval of or notice to the Federal Reserve Board or to any state or other regulatory authority is necessary before the Option may be exercised, cooperating fully with the Holder in preparing such applications or notices and providing such information to the Federal Reserve Board or such other regulatory authority as they may require) in order to permit the Holder to exercise the Option and Issuer duly and effectively to issue shares of Common Stock pursuant hereto; and (iv) promptly to take all action provided herein to protect the rights of the Holder against dilution.
 
4.  This Agreement (and the Option granted hereby) are exchangeable, without expense, at the option of the Holder, upon presentation and surrender of this Agreement at the principal office of Issuer, for other Agreements providing for Options of different denominations entitling the holder thereof to purchase, on the same terms and subject to the same conditions as are set forth herein, in the aggregate the same number of shares of Common Stock purchasable hereunder. The terms “Agreement” and “Option” as used herein include any Stock Option Agreements and related Options for which this Agreement (and the Option granted hereby) may be exchanged. Upon receipt by Issuer of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Agreement, and (in the case of loss, theft or destruction) of reasonably satisfactory indemnification, and upon surrender and cancellation of this Agreement, if mutilated, Issuer will execute and deliver a new Agreement of like tenor and date. Any such new Agreement executed and delivered shall constitute an additional contractual obligation on the part of Issuer, whether or not the Agreement so lost, stolen, destroyed or mutilated shall at any time be enforceable by anyone.
 
5.  In addition to the adjustment in the number of shares of Common Stock that are purchasable upon exercise of the Option pursuant to Section 1 of this Agreement, the number of shares of Common Stock purchasable upon the exercise of the Option and the Option Price shall be subject to adjustment from time to time as provided in this Section 5. In the event of any change in, or distributions in respect of, the Common Stock by reason of stock dividends, split-ups, mergers, recapitalizations, combinations, subdivisions, conversions, exchanges of shares, distributions on or in respect of the Common Stock that would cause an adjustment to the number of shares of Regions Common Stock that each share of AmSouth Common Stock shall represent the right to receive upon conversion under the terms of the Merger Agreement, or the like, the type and number of shares of Common Stock purchasable upon exercise hereof and the Option Price shall be appropriately adjusted in such manner as shall fully preserve the economic benefits provided hereunder and proper provision shall be made in any agreement governing any such transaction to provide for such proper adjustment and the full satisfaction of the Issuer’s obligations hereunder.
 
6.  Upon the occurrence of a Subsequent Triggering Event that occurs prior to an Exercise Termination Event, Issuer shall, at the request of Grantee delivered within 180 days of such Subsequent Triggering Event (whether on its own behalf or on behalf of any subsequent holder of this Option (or part thereof) or any of the shares of Common Stock issued pursuant hereto), promptly prepare, file and keep current a shelf registration statement under the 1933


B-4


Table of Contents

Act covering this Option and any shares issued and issuable pursuant to this Option and shall use its reasonable best efforts to cause such registration statement to become effective and remain current in order to permit the sale or other disposition of this Option and any shares of Common Stock issued upon total or partial exercise of this Option (“Option Shares”) in accordance with any plan of disposition requested by Grantee. Issuer will use its reasonable best efforts to cause such registration statement first to become effective and then to remain effective for such period not in excess of 180 days from the day such registration statement first becomes effective or such shorter time as may be reasonably necessary to effect such sales or other dispositions. Grantee shall have the right to demand two such registrations. The Issuer shall bear the costs of such registrations (including, but not limited to, Issuer’s attorneys’ fees, printing costs and filing fees, except for the fees and disbursements of Grantee’s counsel related thereto). The foregoing notwithstanding, if, at the time of any request by Grantee for registration of the Option or Option Shares as provided above, Issuer is in registration with respect to an underwritten public offering of shares of Common Stock, and if in the good faith judgment of the managing underwriter or managing underwriters, or, if none, the sole underwriter or underwriters, of such offering the inclusion of the Holder’s Option or Option Shares would interfere with the successful marketing of the shares of Common Stock offered by Issuer, the number of Option Shares otherwise to be covered in the registration statement contemplated hereby may be reduced; provided, however, that after any such required reduction the number of Option Shares to be included in such offering for the account of the Holder shall constitute at least 25% of the total number of shares to be sold by the Holder and Issuer in the aggregate; and provided further, however, that if such reduction occurs, then the Issuer shall file a registration statement for the balance as promptly as practicable and no reduction shall thereafter occur. Each such Holder shall provide all information reasonably requested by Issuer for inclusion in any registration statement to be filed hereunder. If requested by any such Holder in connection with such registration, Issuer shall become a party to any underwriting agreement relating to the sale of such shares, but only to the extent of obligating itself in respect of representations, warranties, indemnities and other agreements customarily included in secondary offering underwriting agreements for the Issuer. Upon receiving any request under this Section 6 from any Holder, Issuer agrees to send a copy thereof to any other person known to Issuer to be entitled to registration rights under this Section 6, in each case by promptly mailing the same, postage prepaid, to the address of record of the persons entitled to receive such copies. Notwithstanding anything to the contrary contained herein, in no event shall Issuer be obligated to effect more than two registrations pursuant to this Section 6 by reason of the fact that there shall be more than one Grantee as a result of any assignment or division of this Agreement.
 
7.  (a) In the event of a Repurchase Event (as defined below), (i) following a request of the Holder, delivered prior to an Exercise Termination Event, Issuer (or any successor thereto) shall repurchase the Option from the Holder immediately prior to the Repurchase Event (or, as requested by the Holder, after the Repurchase Event) at a price (the “Option Repurchase Price”) equal to the product of the number of shares for which this Option may then be exercised multiplied by the amount by which (A) the Market/Offer Price (as defined below) exceeds (B) the Option Price, and (ii) at the request of the owner of Option Shares from time to time (the “Owner”), delivered prior to an Exercise Termination Event and within 90 days of the occurrence of a Repurchase Event, Issuer (or any successor thereto) shall repurchase immediately prior to the Repurchase Event (or, as requested by the Owner, after the Repurchase Event) such number of the Option Shares from the Owner as the Owner shall designate at a price (the “Option Share Repurchase Price”) equal to the Market/Offer Price multiplied by the number of Option Shares so designated. The term “Market/Offer Price” shall mean the highest of (i) the price per share of Common Stock at which a tender offer or exchange offer therefor has been made, (ii) the price per share of Common Stock to be paid by any third party pursuant to an agreement with Issuer, (iii) the highest closing price for shares of Common Stock within the six-month period immediately preceding the date the Holder gives notice of the required repurchase of this Option or the Owner gives notice of the required repurchase of Option Shares, as the case may be, and (iv) in the event of a sale of Issuer’s assets, the sum of the price paid in such sale for such assets and the current market value of the remaining assets of Issuer as determined by a nationally recognized investment banking firm selected by the Holder or the Owner, as the case may be, and reasonably acceptable to the Issuer, divided by the number of shares of Common Stock of Issuer outstanding at the time of such sale. In determining the Market/Offer Price, the value of consideration other than cash shall be determined by a nationally recognized investment banking firm selected by the Holder or Owner, as the case may be, and reasonably acceptable to the Issuer.
 
(b) The Holder and the Owner, as the case may be, may exercise its right to require Issuer to repurchase the Option and any Option Shares pursuant to this Section 7 by surrendering for such purpose to Issuer, at its principal

office, this Agreement or certificates for Option Shares, as applicable, accompanied by a written notice or notices stating that the Holder or the Owner, as the case may be, elects to require Issuer to repurchase this Option and/or the Option Shares in accordance with the provisions of this Section 7. Within five business days after the surrender of the Option and/or certificates representing Option Shares and the receipt of such notice or notices relating thereto Issuer shall deliver or cause to be delivered to the Holder the Option Repurchase Price and/or to the Owner the Option Share Repurchase Price therefor or the portion thereof, if any, that Issuer is not then prohibited under applicable law and regulation from so delivering.
 
(c) To the extent that Issuer is prohibited under applicable law or regulation from repurchasing the Option and/or the Option Shares in full, Issuer shall immediately so notify the Holder and/or the Owner and thereafter deliver or cause to be delivered, from time to time, to the Holder and/or the Owner, as appropriate, the portion of the Option Repurchase Price and the Option Share Repurchase Price, respectively, that it is no longer prohibited from delivering, within five business days after the date on which Issuer is no longer so prohibited; provided, however, that if Issuer at any time after delivery of a notice of repurchase pursuant to paragraph (b) of this Section 7 is prohibited under applicable law or regulation from delivering to the Holder and/or the Owner, as appropriate, the Option Repurchase Price and the Option Share Repurchase Price, respectively, in full (and Issuer hereby undertakes to use its reasonable best efforts to obtain all required regulatory and legal approvals and to file any required notices, in each case as promptly as practicable in order to accomplish such repurchase), the Holder or Owner may revoke its notice of repurchase of the Option or the Option Shares either in whole or to the extent of the prohibition, whereupon, in the latter case, Issuer shall promptly (i) deliver to the Holder and/or the Owner, as appropriate, that portion of the Option Repurchase Price or the Option Share Repurchase Price that Issuer is not prohibited from delivering; and (ii) deliver, as appropriate, either (A) to the Holder, a new Stock Option Agreement evidencing the right of the Holder to purchase that number of shares of Common Stock obtained by multiplying the number of shares of Common Stock for which the surrendered Stock Option Agreement was exercisable at the time of delivery of the notice of repurchase by a fraction, the numerator of which is the Option Repurchase Price less the portion thereof theretofore delivered to the Holder and the denominator of which is the Option Repurchase Price, or (B) to the Owner, a certificate for the Option Shares it is then so prohibited from repurchasing.
 
(d) For purposes of this Section 7, a “Repurchase Event” shall be deemed to have occurred (i) upon the consummation of an Acquisition Transaction with respect to Issuer (and not solely involving Issuer and/or one or more subsidiaries of Issuer) (except that the percentage referred to in clause (y) of the definition thereof shall be 50%) or (ii) upon the acquisition by any person of beneficial ownership of 50% or more of the then outstanding shares of Common Stock.
 
8.  (a) In the event that, prior to an Exercise Termination Event, Issuer shall enter into an agreement (i) to consolidate with or merge into any person, other than Grantee or one of its Subsidiaries, and shall not be the continuing or surviving corporation of such consolidation or merger, (ii) to permit any person, other than Grantee or one of its Subsidiaries, to merge into Issuer and Issuer shall be the continuing or surviving corporation, but, in connection with such merger, the then outstanding shares of Common Stock shall be changed into or exchanged for stock or other securities of any other person or cash or any other property or the then outstanding shares of Common Stock shall after such merger represent less than 50% of the outstanding voting shares and voting share equivalents of the merged company, or (iii) to sell or otherwise transfer all or substantially all of its assets to any person, other than Grantee or one of its Subsidiaries, then, and in each such case, the agreement governing such transaction shall make proper provision so that the Option shall, upon the consummation of any such transaction and upon the terms and conditions set forth herein, be converted into, or exchanged for, an option (the “Substitute Option”), at the election of the Holder, of either (x) the Acquiring Corporation (as hereinafter defined) or (y) any person that controls the Acquiring Corporation.
 
(b) The following terms have the meanings indicated:
 
(A) “Acquiring Corporation” shall mean (i) the continuing or surviving person of a consolidation or merger with Issuer (if other than Issuer), (ii) Issuer in a merger in which Issuer is the continuing or surviving person, and (iii) the transferee of all or substantially all of Issuer’s assets.
 
(B) “Substitute Common Stock” shall mean the common stock issued by the issuer of the Substitute Option upon exercise of the Substitute Option.


B-6


Table of Contents

(C) “Assigned Value” shall mean the Market/Offer Price, as defined in Section 7.
 
(D) “Average Price” shall mean the average closing price of a share of the Substitute Common Stock for the one year immediately preceding the consolidation, merger or sale in question, but in no event higher than the closing price of the shares of Substitute Common Stock on the day preceding such consolidation, merger or sale; provided that if Issuer is the issuer of the Substitute Option, the Average Price shall be computed with respect to a share of common stock issued by the person merging into Issuer or by any company which controls or is controlled by such person, as the Holder may elect.
 
(c) The Substitute Option shall have the same terms as the Option, provided, that if the terms of the Substitute Option cannot, for legal reasons, be the same as the Option, such terms shall be as similar as possible and in no event less advantageous to the Holder. The issuer of the Substitute Option shall also enter into an agreement with the then Holder or Holders of the Substitute Option in substantially the same form as this Agreement, which shall be applicable to the Substitute Option.
 
(d) The Substitute Option shall be exercisable for such number of shares of Substitute Common Stock as is equal to the Assigned Value multiplied by the number of shares of Common Stock for which the Option is then exercisable, divided by the Average Price. The exercise price of the Substitute Option per share of Substitute Common Stock shall then be equal to the Option Price multiplied by a fraction, the numerator of which shall be the number of shares of Common Stock for which the Option is then exercisable and the denominator of which shall be the number of shares of Substitute Common Stock for which the Substitute Option is exercisable.
 
(e) In no event, pursuant to any of the foregoing paragraphs, shall the Substitute Option be exercisable for more than 19.9% of the shares of Substitute Common Stock outstanding prior to exercise of the Substitute Option. In the event that the Substitute Option would be exercisable for more than 19.9% of the shares of Substitute Common Stock outstanding prior to exercise but for this clause (e), the issuer of the Substitute Option (the “Substitute Option Issuer”) shall make a cash payment to Holder equal to the excess of (i) the value of the Substitute Option without giving effect to the limitation in this clause (e) over (ii) the value of the Substitute Option after giving effect to the limitation in this clause (e). This difference in value shall be determined by a nationally recognized investment banking firm selected by the Holder or the Owner, as the case may be, and reasonably acceptable to the Acquiring Corporation.
 
(f) Issuer shall not enter into any transaction described in subsection (a) of this Section 8 unless the Acquiring Corporation and any person that controls the Acquiring Corporation assume in writing all the obligations of Issuer hereunder.
 
9.  (a) At the request of the holder of the Substitute Option (the “Substitute Option Holder”), the Substitute Option Issuer shall repurchase the Substitute Option from the Substitute Option Holder at a price (the “Substitute Option Repurchase Price”) equal to the amount by which (i) the Highest Closing Price (as hereinafter defined) exceeds (ii) the exercise price of the Substitute Option, multiplied by the number of shares of Substitute Common Stock for which the Substitute Option may then be exercised, and at the request of the owner (the “Substitute Share Owner”) of shares of Substitute Common Stock (the “Substitute Shares”), the Substitute Option Issuer shall repurchase the Substitute Shares at a price (the “Substitute Share Repurchase Price”) equal to the Highest Closing Price multiplied by the number of Substitute Shares so designated. The term “Highest Closing Price” shall mean the highest closing price for shares of Substitute Common Stock within the six-month period immediately preceding the date the Substitute Option Holder gives notice of the required repurchase of the Substitute Option or the Substitute Share Owner gives notice of the required repurchase of the Substitute Shares, as applicable.
 
(b) The Substitute Option Holder and the Substitute Share Owner, as the case may be, may exercise its respective right to require the Substitute Option Issuer to repurchase the Substitute Option and the Substitute Shares pursuant to this Section 9 by surrendering for such purpose to the Substitute Option Issuer, at its principal office, the agreement for such Substitute Option (or, in the absence of such an agreement, a copy of this Agreement) and certificates for Substitute Shares accompanied by a written notice or notices stating that the Substitute Option Holder or the Substitute Share Owner, as the case may be, elects to require the Substitute Option Issuer to repurchase the Substitute Option and/or the Substitute Shares in accordance with the provisions of this Section 9. As promptly as practicable, and in any event within five business days after the surrender of the Substitute Option

and/or certificates representing Substitute Shares and the receipt of such notice or notices relating thereto, the Substitute Option Issuer shall deliver or cause to be delivered to the Substitute Option Holder the Substitute Option Repurchase Price and/or to the Substitute Share Owner the Substitute Share Repurchase Price therefor or, in either case, the portion thereof which the Substitute Option Issuer is not then prohibited under applicable law and regulation from so delivering.
 
(c) To the extent that the Substitute Option Issuer is prohibited under applicable law or regulation from repurchasing the Substitute Option and/or the Substitute Shares in part or in full, the Substitute Option Issuer following a request for repurchase pursuant to this Section 9 shall immediately so notify the Substitute Option Holder and/or the Substitute Share Owner and thereafter deliver or cause to be delivered, from time to time, to the Substitute Option Holder and/or the Substitute Share Owner, as appropriate, the portion of the Substitute Share Repurchase Price, respectively, which it is no longer prohibited from delivering, within five business days after the date on which the Substitute Option Issuer is no longer so prohibited; provided, however, that if the Substitute Option Issuer is at any time after delivery of a notice of repurchase pursuant to subsection (b) of this Section 9 prohibited under applicable law or regulation from delivering to the Substitute Option Holder and/or the Substitute Share Owner, as appropriate, the Substitute Option Repurchase Price and the Substitute Share Repurchase Price, respectively, in full (and the Substitute Option Issuer shall use its reasonable best efforts to obtain all required regulatory and legal approvals, in each case as promptly as practicable, in order to accomplish such repurchase), the Substitute Option Holder or Substitute Share Owner may revoke its notice of repurchase of the Substitute Option or the Substitute Shares either in whole or to the extent of the prohibition, whereupon, in the latter case, the Substitute Option Issuer shall promptly (i) deliver to the Substitute Option Holder or Substitute Share Owner, as appropriate, that portion of the Substitute Option Repurchase Price or the Substitute Share Repurchase Price that the Substitute Option Issuer is not prohibited from delivering; and (ii) deliver, as appropriate, either (A) to the Substitute Option Holder, a new Substitute Option evidencing the right of the Substitute Option Holder to purchase that number of shares of the Substitute Common Stock obtained by multiplying the number of shares of the Substitute Common Stock for which the surrendered Substitute Option was exercisable at the time of delivery of the notice of repurchase by a fraction, the numerator of which is the Substitute Option Repurchase Price less the portion thereof theretofore delivered to the Substitute Option Holder and the denominator of which is the Substitute Option Repurchase Price, or (B) to the Substitute Share Owner, a certificate for the Substitute Common Stock it is then so prohibited from repurchasing.
 
10.  The 90-day or 180-day periods for exercise of certain rights under Sections 2, 6, 7 and 13 shall be extended: (i) to the extent necessary to obtain all regulatory approvals for the exercise of such rights and for the expiration of all statutory waiting periods; (ii) to the extent necessary to avoid liability under Section 16(b) of the 1934 Act by reason of such exercise; and (3) when there exists an Order that prohibits or delays exercise of such right.
 
11.  Issuer hereby represents and warrants to Grantee as follows:
 
(a) Issuer has full corporate power and authority to execute and deliver this Agreement and to consummate the transactions contemplated hereby.

The execution and delivery of this Agreement and the consummation of the transactions contemplated hereby have been duly authorized by all necessary corporate action on the part of Grantee.

(b) The Option is not being, and any shares of Common Stock or other securities acquired by Grantee upon exercise of the Option will not be, acquired with a view to the public distribution thereof and will not be transferred or otherwise disposed of except in a transaction registered or exempt from registration under the 1933 Act.
 
13.  Neither of the parties hereto may assign any of its rights or obligations under this Agreement or the Option created hereunder to any other person, without the express written consent of the other party, except that in the event a Subsequent Triggering Event shall have occurred prior to an Exercise Termination Event, Grantee, subject to the express provisions hereof, may assign in whole or in part its rights and obligations hereunder within 180 days following such Subsequent Triggering Event; provided, however, that until the date 15 days following the date on which the Federal Reserve Board approves an application by Grantee or its transferee under the BHCA to acquire the shares of Common Stock subject to the Option, Grantee may not assign its rights under the Option except in (i) a widely dispersed public distribution, (ii) a private placement in which no one party acquires the right to purchase in excess of 2% of the voting shares of Issuer, (iii) an assignment to a single party (e.g.  , a broker or investment banker) for the purpose of conducting a widely dispersed public distribution on Grantee’s behalf, or (iv) any other manner approved by the Federal Reserve Board.
 
14.  Each of Grantee and Issuer will use its reasonable best efforts to make all filings with, and to obtain consents of, all third parties and governmental authorities necessary to the consummation of the transactions contemplated by this Agreement, including without limitation making application to list the shares of Common Stock issuable hereunder on the New York Stock Exchange upon official notice of issuance and applying to the Federal Reserve Board under the BHCA for approval to acquire the shares issuable hereunder, but Grantee shall not be obligated to apply to state banking authorities for approval to acquire the shares of Common Stock issuable hereunder until such time, if ever, as it deems appropriate to do so.
 
15.  (a) Grantee may, at any time during which Issuer would be required to repurchase the Option or any Option Shares pursuant to Section 7 upon proper request or notice, surrender the Option (together with any Option Shares issued to and then owned by Grantee) to Issuer in exchange for a cash fee equal to the Surrender Price (as defined below); provided, however, that Grantee may not exercise its rights pursuant to this Section 15 if Issuer has repurchased the Option (or any portion thereof) or any Option Shares pursuant to Section 7. The “Surrender Price” shall be equal to (i) $343,962,190, plus (ii) if applicable, the aggregate purchase price previously paid pursuant hereto by Grantee with respect to any Option Shares, minus (iii) if applicable, the sum of (A) the excess of (1) the net cash amounts, if any, received by Grantee pursuant to the arms’ length sale of Option Shares (or any other securities into which such Option Shares were converted or exchanged) to any party not affiliated with Grantee, over (2) the aggregate purchase price previously paid pursuant hereto by Grantee with respect to such Option Shares and (B) the net cash amounts, if any, received by Grantee pursuant to an arms’ length sale of a portion of the Option to any party not affiliated with Grantee.
 
(b) Grantee may exercise its right to surrender the Option and any Option Shares pursuant to this Section 15 by surrendering to Issuer, at its principal office, this Agreement together with certificates for Option Shares, if any, accompanied by a written notice stating (i) that Grantee elects to surrender the Option and Option Shares, if any, in accordance with the provisions of this Section 15 and (ii) the Surrender Price. The Surrender Price shall be payable in immediately available funds on or before the second business day following receipt of such notice by Issuer.
 
(c) To the extent that Issuer is prohibited under applicable law or regulation from paying the Surrender Price to Grantee in full, Issuer shall immediately so notify Grantee and thereafter deliver or cause to be delivered, from time


B-9

to time, to Grantee, the portion of the Surrender Price that Issuer is no longer prohibited from paying, within five business days after the date on which Issuer is no longer so prohibited, provided, however, that if Issuer at any time after delivery of a notice of surrender pursuant to paragraph (b) of this Section 15 is prohibited under applicable law or regulation from paying to Grantee the Surrender Price in full (i) Issuer shall (A) use its reasonable best efforts to obtain all required regulatory and legal approvals and to file any required notices as promptly as practicable in order to make such payments, (B) within five days of the submission or receipt of any documents relating to any such regulatory and legal approvals, provide Grantee with copies of the same, and (C) keep Grantee advised of both the status of any such request for regulatory and legal approvals, as well as any discussions with any relevant regulatory or other third party reasonably related to the same and (ii) Grantee may revoke such notice of surrender by delivery of a notice of revocation to Issuer and, upon delivery of such notice of revocation, the Exercise Termination Date shall be extended to a date six months from the date on which the Exercise Termination Date would have occurred if not for the provisions of this Section 15(c) (during which period Grantee may exercise any of its rights hereunder, including any and all rights pursuant to this Section 15).
 
(d) Grantee shall have rights substantially identical to those set forth in paragraphs (a), (b) and (c) of this Section 15 with respect to the Substitute Option and the Substitute Option Issuer during any period in which the Substitute Option Issuer would be required to repurchase the Substitute Option pursuant to Section 9.
 
16.  (a) Notwithstanding any other provision of this Agreement, in no event shall the Grantee’s Total Profit (as hereinafter defined) exceed $393,099,645 and, if it otherwise would exceed such amount, the Grantee, at its sole election, shall either (i) reduce the number of shares of Common Stock subject to this Option, (ii) deliver to Issuer for cancellation Option Shares previously purchased by Grantee, (iii) pay cash to Issuer, or (iv) any combination thereof, so that Grantee’s actually realized Total Profit shall not exceed $393,099,645 after taking into account the foregoing actions.
 
(b) Notwithstanding any other provision of this Agreement, this Option may not be exercised for a number of shares as would, as of the date of exercise, result in a Notional Total Profit (as defined below) of more than $393,099,645; provided that nothing in this sentence shall restrict any exercise of the Option permitted hereby on any date subsequent to such initial date of exercise.
 
(c) As used herein, the term “Total Profit” shall mean the aggregate amount (before taxes) of the following: (i) the amount received by Grantee pursuant to Issuer’s repurchase of the Option (or any portion thereof) pursuant to Section 7, (ii) (x) the amount received by Grantee pursuant to Issuer’s repurchase of Option Shares pursuant to Section 7, less (y) the Grantee’s purchase price for such Option Shares, (iii) (x) the net cash amounts received by Grantee pursuant to the sale of Option Shares (or any other securities into which such Option Shares are converted or exchanged) to any unaffiliated party, less (y) the Grantee’s purchase price of such Option Shares, (iv) any amounts received by Grantee on the transfer of the Option (or any portion thereof) to any unaffiliated party, and (v) any amount equivalent to the foregoing with respect to the Substitute Option.
 
(d) As used herein, the term “Notional Total Profit” with respect to any number of shares as to which Grantee may propose to exercise this Option shall be the Total Profit determined as of the date of such proposed exercise assuming that this Option were exercised on such date for such number of shares and assuming that such shares, together with all other Option Shares held by Grantee and its affiliates as of such date, were sold for cash at the closing market price for the Common Stock as of the close of business on the preceding trading day (less customary brokerage commissions).
 
17.  The parties hereto acknowledge that damages would be an inadequate remedy for a breach of this Agreement by either party hereto and that the obligations of the parties hereto shall be enforceable by either party hereto through injunctive or other equitable relief.
 
18.  If any term, provision, covenant or restriction contained in this Agreement is held by a court or a federal or state regulatory agency of competent jurisdiction to be invalid, void or unenforceable, the remainder of the terms, provisions and covenants and restrictions contained in this Agreement shall remain in full force and effect, and shall in no way be affected, impaired or invalidated. If for any reason such court or regulatory agency determines that the Holder is not permitted to acquire, or Issuer is not permitted to repurchase pursuant to Section 7, the full number of shares of Common Stock provided in Section 1(a) hereof (as adjusted pursuant to Section 1(b) or 5 hereof), it is the

THE TRANSFER OF THIS AGREEMENT IS SUBJECT TO
CERTAIN PROVISIONS CONTAINED HEREIN AND TO
RESALE RESTRICTIONS UNDER THE
SECURITIES ACT OF 1933, AS AMENDED
 
STOCK OPTION AGREEMENT (this “Agreement”), dated May 24, 2006, between Regions Financial Corporation, a Delaware corporation (“Issuer”), and AmSouth Bancorporation, a Delaware corporation (“Grantee”).
 
W I T N E S S E T H:
 
WHEREAS, Grantee and Issuer have entered into an Agreement and Plan of Merger of even date herewith (the “Merger Agreement”), which agreement has been executed and delivered by the parties hereto simultaneously with this Agreement;
 
WHEREAS, as a condition to Grantee’s entering into the Merger Agreement and in consideration therefor, Issuer has agreed to grant Grantee the Option (as hereinafter defined); and
 
WHEREAS, in connection with entering into the Merger Agreement, the Grantee has issued the Issuer an option (the “Reciprocal Option”) pursuant to a Stock Option Agreement in the form attached to the Merger Agreement.
 
NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements set forth herein and in the Merger Agreement, the parties hereto agree as follows:
 
1.  (a) Issuer hereby grants to Grantee an unconditional, irrevocable option (the “Option”) to purchase, subject to the terms hereof, up to 90,767,194 fully paid and nonassessable shares of Issuer’s Common Stock, par value $0.01 per share (“Common Stock”), at a price of the lesser (i) $35.53 per share and (ii) the closing sale price of the Common Stock on the NYSE Composite Transaction Tape on the trading day immediately preceding the exercise date as reported by The Wall Street Journal or, if not reported therein, in another authoritative source (the “Option Price”); provided, however, that in no event shall the number of shares of Common Stock for which this Option is exercisable exceed 19.9% of the Issuer’s issued and outstanding shares of Common Stock without giving effect to any shares subject to or issued pursuant to the Option. The number of shares of Common Stock that may be received upon the exercise of the Option and the Option Price are subject to adjustment as herein set forth. If Issuer adopts a shareholder protection rights plan or similar agreement, Issuer shall make proper provision so that each share of Common Stock issued upon exercise of the Option shall be accompanied by the applicable number of rights under such agreement.
 
(b) In the event that any additional shares of Common Stock are either (i) issued or otherwise become outstanding after the date of this Agreement (other than pursuant to this Agreement) or (ii) redeemed, repurchased, retired or otherwise cease to be outstanding after the date of this Agreement, the number of shares of Common Stock subject to the Option shall be increased or decreased, as appropriate, so that, after such issuance, such number equals 19.9% of the number of shares of Common Stock then issued and outstanding without giving effect to any shares subject or issued pursuant to the Option. Nothing contained in this Section 1(b) or elsewhere in this Agreement shall be deemed to authorize Issuer or Grantee to breach any provision of the Merger Agreement.
 
2.  (a)  The Holder (as hereinafter defined) may exercise the Option, in whole or part, and from time to time, if, but only if, both an Initial Triggering Event (as hereinafter defined) and a Subsequent Triggering Event (as hereinafter defined) shall have occurred prior to the occurrence of an Exercise Termination Event (as hereinafter


C-1

defined), provided that the Holder shall have sent the written notice of such exercise (as provided in subsection (g) of this Section 2) within 180 days following such Subsequent Triggering Event.
 
(b) Each of the following shall be an “Exercise Termination Event”: (i) the Effective Time (as defined in the Merger Agreement) of the Merger; (ii) termination of the Merger Agreement in accordance with the provisions thereof (other than a termination by Grantee pursuant to Section 6.1(e) or pursuant to Section 6.1(b) (unless the breach by Issuer giving rise to such right of termination pursuant to Section 6.1(b) is non-volitional)) if such termination occurs prior to the occurrence of an Initial Triggering Event; and (iii) the passage of 18 months after termination of the Merger Agreement if such termination follows the occurrence of an Initial Triggering Event or is a termination by Grantee pursuant to Section 6.1(e) or pursuant to Section 6.1(b) (unless the breach by Issuer giving rise to such right of termination pursuant to Section 6.1(b) is non-volitional) of the Merger Agreement.
 
(c) The term “Holder” shall mean the holder or holders of the Option.
 
(d) The term “Initial Triggering Event” shall mean any of the following events or transactions occurring on or after the date hereof:
 
(i) Issuer or any of its Subsidiaries (each an “Issuer Subsidiary”), without having received Grantee’s prior written consent, shall have entered into an agreement to engage in an Acquisition Transaction (as hereinafter defined) with any person (the term “person” for purposes of this Agreement having the meaning assigned thereto in Sections 3(a)(9) and 13(d)(3) of the Securities Exchange Act of 1934, as amended (the “1934 Act”), and the rules and regulations thereunder) other than Grantee or any of its Subsidiaries (each a “Grantee Subsidiary”) or the Board of Directors of Issuer shall have recommended that the stockholders of Issuer approve or accept any Acquisition Transaction with any person other than Grantee or a Subsidiary of Grantee. For purposes of this Agreement, “Acquisition Transaction” shall mean (w) a merger, consolidation or share exchange, or any similar transaction, involving Issuer or any Significant Subsidiary (as defined in Rule 1-02 of Regulation S-X promulgated by the Securities and Exchange Commission (the “SEC”)) of Issuer, (x) a purchase, lease or other acquisition or assumption of all or a substantial portion of the assets or deposits of Issuer or any Significant Subsidiary of Issuer, (y) a purchase or other acquisition (including by way of merger, consolidation, share exchange or otherwise) of securities representing 10% or more of the voting power of Issuer, or (z) any substantially similar transaction; provided, however, that in no event shall any merger, consolidation, purchase or similar transaction that is not entered into in violation of the terms of the Merger Agreement and involves only the Issuer and one or more of its wholly-owned Subsidiaries or only any two or more of such wholly-owned Subsidiaries, be deemed to be an Acquisition Transaction;
 
(ii) Issuer or any Issuer Subsidiary, without having received Grantee’s prior written consent, shall have authorized, recommended, proposed or publicly announced its intention to authorize, recommend or propose, to engage in an Acquisition Transaction with any person other than Grantee or a Grantee Subsidiary, or the Board of Directors of Issuer shall have publicly withdrawn or modified, or publicly announced its intention to withdraw or modify, in any manner adverse to Grantee, its recommendation that the stockholders of Issuer approve the transactions contemplated by the Merger Agreement;
 
(iii) Any person other than Grantee, any Grantee Subsidiary or any Issuer Subsidiary acting in a fiduciary capacity in the ordinary course of its business shall have acquired beneficial ownership or the right to acquire beneficial ownership of 10% or more of the outstanding shares of Common Stock (the term “beneficial ownership” for purposes of this Agreement having the meaning assigned thereto in Section 13(d) of the 1934 Act, and the rules and regulations thereunder);
 
(iv) Any person other than Grantee or any Grantee Subsidiary shall have made a bona fide proposal to Issuer or its stockholders that is public or becomes the subject of public disclosure to engage in an Acquisition Transaction;
 
(v) After the receipt by Issuer or its stockholders of any bona fide inquiry or proposal (or the bona fide indication of any intention to propose) from a third party to engage in an Acquisition Transaction, Issuer shall have breached any covenant or obligation contained in the Merger Agreement and such breach (x) would entitle Grantee to terminate the Merger Agreement and (y) shall not have been cured prior to the Notice Date (as defined below); or


C-2


Table of Contents

(vi) Any person other than Grantee or any Grantee Subsidiary, other than in connection with a transaction to which Grantee has given its prior written consent, shall have filed an application or notice with the Federal Reserve Board, or other federal or state bank regulatory authority, which application or notice has been accepted for processing, for approval to engage in an Acquisition Transaction.
 
(e) The term “Subsequent Triggering Event” shall mean either of the following events or transactions occurring on or after the date hereof:
 
(i) The acquisition by any person of beneficial ownership of 20% or more of the then outstanding Common Stock; or
 
(ii) The occurrence of the Initial Triggering Event described in paragraph (i) of subsection (d) of this Section 2, except that the percentage referred to in clause (y) shall be 20%.
 
(f) Issuer shall notify Grantee promptly in writing of the occurrence of any Initial Triggering Event or Subsequent Triggering Event of which it has knowledge, it being understood that the giving of such notice by Issuer shall not be a condition to the right of the Holder to exercise the Option.
 
(g) In the event the Holder is entitled to and wishes to exercise the Option, it shall send to Issuer a written notice (the date of which being herein referred to as the “Notice Date”) specifying (i) the total number of shares it will purchase pursuant to such exercise and (ii) a place and date not earlier than three business days nor later than 60 business days from the Notice Date for the closing of such purchase (the “Closing Date”); provided that if prior notification to or approval of the Federal Reserve Board or any other regulatory agency is required in connection with such purchase, the Holder shall as soon as reasonably practicable file the required notice or application for approval and shall expeditiously process the same, and the period of time that otherwise would run pursuant to this sentence shall run instead from the date on which any required notification periods have expired or been terminated or such approvals have been obtained and any requisite waiting period or periods shall have passed. Any exercise of the Option shall be deemed to occur on the Notice Date relating thereto.
 
(h) At the closing referred to in subsection (g) of this Section 2, the Holder shall pay to Issuer the aggregate purchase price for the shares of Common Stock purchased pursuant to the exercise of the Option in immediately available funds by wire transfer to a bank account designated by Issuer, provided that failure or refusal of Issuer to designate such a bank account shall not preclude the Holder from exercising the Option.
 
(i) At such closing, simultaneously with the delivery of immediately available funds as provided in subsection (h) of this Section 2, Issuer shall deliver to the Holder a certificate or certificates representing the number of shares of Common Stock purchased by the Holder and, if the Option should be exercised in part only, a new Option evidencing the rights of the Holder thereof to purchase the balance of the shares purchasable hereunder, and the Holder shall deliver to Issuer this Agreement and a letter agreeing that the Holder will not offer to sell or otherwise dispose of such shares in violation of applicable law or the provisions of this Agreement.
 
(j) Certificates for Common Stock delivered at a closing hereunder may be endorsed with a restrictive legend that shall read substantially as follows:
 
“The transfer of the shares represented by this certificate is subject to certain provisions of an agreement between the registered holder hereof and Issuer and to resale restrictions arising under the Securities Act of 1933, as amended. A copy of such agreement is on file at the principal office of Issuer and will be provided to the holder hereof without charge upon receipt by Issuer of a written request therefor.”
 
It is understood and agreed that: (i) the reference to the resale restrictions of the Securities Act of 1933, as amended (the “1933 Act”), in the above legend shall be removed by delivery of substitute certificate(s) without such reference if the Holder shall have delivered to Issuer a copy of a letter from the staff of the SEC, or an opinion of counsel, in form and substance reasonably satisfactory to Issuer, to the effect that such legend is not required for purposes of the 1933 Act; (ii) the reference to the provisions of this Agreement in the above legend shall be removed by delivery of substitute certificate(s) without such reference if the shares have been sold or transferred in compliance with the provisions of this Agreement and under circumstances that do not require the retention of such reference; and (iii) the legend shall be removed in its entirety if the conditions in the preceding clauses (i) and (ii) are both satisfied. In addition, such certificates shall bear any other legend as may be required by law.

(k) Upon the giving by the Holder to Issuer of the written notice of exercise of the Option provided for under subsection (g) of this Section 2 and the tender of the applicable purchase price in immediately available funds, the Holder shall be deemed to be the holder of record of the shares of Common Stock issuable upon such exercise, notwithstanding that the stock transfer books of Issuer shall then be closed or that certificates representing such shares of Common Stock shall not then be actually delivered to the Holder. Issuer shall pay all expenses, and any and all United States federal, state and local taxes and other charges that may be payable in connection with the preparation, issuance and delivery of stock certificates under this Section 2 in the name of the Holder or its assignee, transferee or designee.
 
3.  Issuer agrees: (i) that it shall at all times maintain, free from preemptive rights, sufficient authorized but unissued shares of Common Stock so that the Option may be exercised without additional authorization of Common Stock after giving effect to all other options, warrants, convertible securities and other rights to purchase Common Stock; (ii) that it will not, by charter amendment or through reorganization, consolidation, merger, dissolution or sale of assets, or by any other voluntary act, avoid or seek to avoid the observance or performance of any of the covenants, stipulations or conditions to be observed or performed hereunder by Issuer; (iii) promptly to take all action as may from time to time be required (including (x) complying with all premerger notification, reporting and waiting period requirements specified in 15 U.S.C. § 18a and regulations promulgated thereunder and (y) in the event, under the Bank Holding Company Act of 1956, as amended (the “BHCA”), or the Change in Bank Control Act of 1978, as amended, or any state banking law, prior approval of or notice to the Federal Reserve Board or to any state or other regulatory authority is necessary before the Option may be exercised, cooperating fully with the Holder in preparing such applications or notices and providing such information to the Federal Reserve Board or such other regulatory authority as they may require) in order to permit the Holder to exercise the Option and Issuer duly and effectively to issue shares of Common Stock pursuant hereto; and (iv) promptly to take all action provided herein to protect the rights of the Holder against dilution.
 
4.  This Agreement (and the Option granted hereby) are exchangeable, without expense, at the option of the Holder, upon presentation and surrender of this Agreement at the principal office of Issuer, for other Agreements providing for Options of different denominations entitling the holder thereof to purchase, on the same terms and subject to the same conditions as are set forth herein, in the aggregate the same number of shares of Common Stock purchasable hereunder. The terms “Agreement” and “Option” as used herein include any Stock Option Agreements and related Options for which this Agreement (and the Option granted hereby) may be exchanged. Upon receipt by Issuer of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Agreement, and (in the case of loss, theft or destruction) of reasonably satisfactory indemnification, and upon surrender and cancellation of this Agreement, if mutilated, Issuer will execute and deliver a new Agreement of like tenor and date. Any such new Agreement executed and delivered shall constitute an additional contractual obligation on the part of Issuer, whether or not the Agreement so lost, stolen, destroyed or mutilated shall at any time be enforceable by anyone.
 
5.  In addition to the adjustment in the number of shares of Common Stock that are purchasable upon exercise of the Option pursuant to Section 1 of this Agreement, the number of shares of Common Stock purchasable upon the exercise of the Option and the Option Price shall be subject to adjustment from time to time as provided in this Section 5. In the event of any change in, or distributions in respect of, the Common Stock by reason of stock dividends, split-ups, mergers, recapitalizations, combinations, subdivisions, conversions, exchanges of shares, distributions on or in respect of the Common Stock that would cause an adjustment to the number of shares of Regions Common Stock that each share of AmSouth Common Stock shall represent the right to receive upon conversion under the terms of the Merger Agreement, or the like, the type and number of shares of Common Stock purchasable upon exercise hereof and the Option Price shall be appropriately adjusted in such manner as shall fully preserve the economic benefits provided hereunder and proper provision shall be made in any agreement governing any such transaction to provide for such proper adjustment and the full satisfaction of the Issuer’s obligations hereunder.
 
6.  Upon the occurrence of a Subsequent Triggering Event that occurs prior to an Exercise Termination Event, Issuer shall, at the request of Grantee delivered within 180 days of such Subsequent Triggering Event (whether on its own behalf or on behalf of any subsequent holder of this Option (or part thereof) or any of the shares of Common Stock issued pursuant hereto), promptly prepare, file and keep current a shelf registration statement under the 1933


C-4


Table of Contents

Act covering this Option and any shares issued and issuable pursuant to this Option and shall use its reasonable best efforts to cause such registration statement to become effective and remain current in order to permit the sale or other disposition of this Option and any shares of Common Stock issued upon total or partial exercise of this Option (“Option Shares”) in accordance with any plan of disposition requested by Grantee. Issuer will use its reasonable best efforts to cause such registration statement first to become effective and then to remain effective for such period not in excess of 180 days from the day such registration statement first becomes effective or such shorter time as may be reasonably necessary to effect such sales or other dispositions. Grantee shall have the right to demand two such registrations. The Issuer shall bear the costs of such registrations (including, but not limited to, Issuer’s attorneys’ fees, printing costs and filing fees, except for the fees and disbursements of Grantee’s counsel related thereto). The foregoing notwithstanding, if, at the time of any request by Grantee for registration of the Option or Option Shares as provided above, Issuer is in registration with respect to an underwritten public offering of shares of Common Stock, and if in the good faith judgment of the managing underwriter or managing underwriters, or, if none, the sole underwriter or underwriters, of such offering the inclusion of the Holder’s Option or Option Shares would interfere with the successful marketing of the shares of Common Stock offered by Issuer, the number of Option Shares otherwise to be covered in the registration statement contemplated hereby may be reduced; provided, however, that after any such required reduction the number of Option Shares to be included in such offering for the account of the Holder shall constitute at least 25% of the total number of shares to be sold by the Holder and Issuer in the aggregate; and provided further, however, that if such reduction occurs, then the Issuer shall file a registration statement for the balance as promptly as practicable and no reduction shall thereafter occur. Each such Holder shall provide all information reasonably requested by Issuer for inclusion in any registration statement to be filed hereunder. If requested by any such Holder in connection with such registration, Issuer shall become a party to any underwriting agreement relating to the sale of such shares, but only to the extent of obligating itself in respect of representations, warranties, indemnities and other agreements customarily included in secondary offering underwriting agreements for the Issuer. Upon receiving any request under this Section 6 from any Holder, Issuer agrees to send a copy thereof to any other person known to Issuer to be entitled to registration rights under this Section 6, in each case by promptly mailing the same, postage prepaid, to the address of record of the persons entitled to receive such copies. Notwithstanding anything to the contrary contained herein, in no event shall Issuer be obligated to effect more than two registrations pursuant to this Section 6 by reason of the fact that there shall be more than one Grantee as a result of any assignment or division of this Agreement.
 
7.  (a) In the event of a Repurchase Event (as defined below), (i) following a request of the Holder, delivered prior to an Exercise Termination Event, Issuer (or any successor thereto) shall repurchase the Option from the Holder immediately prior to the Repurchase Event (or, as requested by the Holder, after the Repurchase Event) at a price (the “Option Repurchase Price”) equal to the product of the number of shares for which this Option may then be exercised multiplied by the amount by which (A) the Market/Offer Price (as defined below) exceeds (B) the Option Price, and (ii) at the request of the owner of Option Shares from time to time (the “Owner”), delivered prior to an Exercise Termination Event and within 90 days of the occurrence of a Repurchase Event, Issuer (or any successor thereto) shall repurchase immediately prior to the Repurchase Event (or, as requested by the Owner, after the Repurchase Event) such number of the Option Shares from the Owner as the Owner shall designate at a price (the “Option Share Repurchase Price”) equal to the Market/Offer Price multiplied by the number of Option Shares so designated. The term “Market/Offer Price” shall mean the highest of (i) the price per share of Common Stock at which a tender offer or exchange offer therefor has been made, (ii) the price per share of Common Stock to be paid by any third party pursuant to an agreement with Issuer, (iii) the highest closing price for shares of Common Stock within the six-month period immediately preceding the date the Holder gives notice of the required repurchase of this Option or the Owner gives notice of the required repurchase of Option Shares, as the case may be, and (iv) in the event of a sale of Issuer’s assets, the sum of the price paid in such sale for such assets and the current market value of the remaining assets of Issuer as determined by a nationally recognized investment banking firm selected by the Holder or the Owner, as the case may be, and reasonably acceptable to the Issuer, divided by the number of shares of Common Stock of Issuer outstanding at the time of such sale. In determining the Market/Offer Price, the value of consideration other than cash shall be determined by a nationally recognized investment banking firm selected by the Holder or Owner, as the case may be, and reasonably acceptable to the Issuer.
 
(b) The Holder and the Owner, as the case may be, may exercise its right to require Issuer to repurchase the Option and any Option Shares pursuant to this Section 7 by surrendering for such purpose to Issuer, at its principal

office, this Agreement or certificates for Option Shares, as applicable, accompanied by a written notice or notices stating that the Holder or the Owner, as the case may be, elects to require Issuer to repurchase this Option and/or the Option Shares in accordance with the provisions of this Section 7. Within five business days after the surrender of the Option and/or certificates representing Option Shares and the receipt of such notice or notices relating thereto Issuer shall deliver or cause to be delivered to the Holder the Option Repurchase Price and/or to the Owner the Option Share Repurchase Price therefor or the portion thereof, if any, that Issuer is not then prohibited under applicable law and regulation from so delivering.
 
(c) To the extent that Issuer is prohibited under applicable law or regulation from repurchasing the Option and/or the Option Shares in full, Issuer shall immediately so notify the Holder and/or the Owner and thereafter deliver or cause to be delivered, from time to time, to the Holder and/or the Owner, as appropriate, the portion of the Option Repurchase Price and the Option Share Repurchase Price, respectively, that it is no longer prohibited from delivering, within five business days after the date on which Issuer is no longer so prohibited; provided, however, that if Issuer at any time after delivery of a notice of repurchase pursuant to paragraph (b) of this Section 7 is prohibited under applicable law or regulation from delivering to the Holder and/or the Owner, as appropriate, the Option Repurchase Price and the Option Share Repurchase Price, respectively, in full (and Issuer hereby undertakes to use its reasonable best efforts to obtain all required regulatory and legal approvals and to file any required notices, in each case as promptly as practicable in order to accomplish such repurchase), the Holder or Owner may revoke its notice of repurchase of the Option or the Option Shares either in whole or to the extent of the prohibition, whereupon, in the latter case, Issuer shall promptly (i) deliver to the Holder and/or the Owner, as appropriate, that portion of the Option Repurchase Price or the Option Share Repurchase Price that Issuer is not prohibited from delivering; and (ii) deliver, as appropriate, either (A) to the Holder, a new Stock Option Agreement evidencing the right of the Holder to purchase that number of shares of Common Stock obtained by multiplying the number of shares of Common Stock for which the surrendered Stock Option Agreement was exercisable at the time of delivery of the notice of repurchase by a fraction, the numerator of which is the Option Repurchase Price less the portion thereof theretofore delivered to the Holder and the denominator of which is the Option Repurchase Price, or (B) to the Owner, a certificate for the Option Shares it is then so prohibited from repurchasing.
 
(d) For purposes of this Section 7, a “Repurchase Event” shall be deemed to have occurred (i) upon the consummation of an Acquisition Transaction with respect to Issuer (and not solely involving Issuer and/or one or more subsidiaries of Issuer) (except that the percentage referred to in clause (y) of the definition thereof shall be 50%) or (ii) upon the acquisition by any person of beneficial ownership of 50% or more of the then outstanding shares of Common Stock.
 
8.  (a) In the event that, prior to an Exercise Termination Event, Issuer shall enter into an agreement (i) to consolidate with or merge into any person, other than Grantee or one of its Subsidiaries, and shall not be the continuing or surviving corporation of such consolidation or merger, (ii) to permit any person, other than Grantee or one of its Subsidiaries, to merge into Issuer and Issuer shall be the continuing or surviving corporation, but, in connection with such merger, the then outstanding shares of Common Stock shall be changed into or exchanged for stock or other securities of any other person or cash or any other property or the then outstanding shares of Common Stock shall after such merger represent less than 50% of the outstanding voting shares and voting share equivalents of the merged company, or (iii) to sell or otherwise transfer all or substantially all of its assets to any person, other than Grantee or one of its Subsidiaries, then, and in each such case, the agreement governing such transaction shall make proper provision so that the Option shall, upon the consummation of any such transaction and upon the terms and conditions set forth herein, be converted into, or exchanged for, an option (the “Substitute Option”), at the election of the Holder, of either (x) the Acquiring Corporation (as hereinafter defined) or (y) any person that controls the Acquiring Corporation.
 
(b) The following terms have the meanings indicated:
 
(A) “Acquiring Corporation” shall mean (i) the continuing or surviving person of a consolidation or merger with Issuer (if other than Issuer), (ii) Issuer in a merger in which Issuer is the continuing or surviving person, and (iii) the transferee of all or substantially all of Issuer’s assets.
 
(B) “Substitute Common Stock” shall mean the common stock issued by the issuer of the Substitute Option upon exercise of the Substitute Option.


C-6


Table of Contents

(C) “Assigned Value” shall mean the Market/Offer Price, as defined in Section 7.
 
(D) “Average Price” shall mean the average closing price of a share of the Substitute Common Stock for the one year immediately preceding the consolidation, merger or sale in question, but in no event higher than the closing price of the shares of Substitute Common Stock on the day preceding such consolidation, merger or sale; provided that if Issuer is the issuer of the Substitute Option, the Average Price shall be computed with respect to a share of common stock issued by the person merging into Issuer or by any company which controls or is controlled by such person, as the Holder may elect.
 
(c) The Substitute Option shall have the same terms as the Option, provided, that if the terms of the Substitute Option cannot, for legal reasons, be the same as the Option, such terms shall be as similar as possible and in no event less advantageous to the Holder. The issuer of the Substitute Option shall also enter into an agreement with the then Holder or Holders of the Substitute Option in substantially the same form as this Agreement, which shall be applicable to the Substitute Option.
 
(d) The Substitute Option shall be exercisable for such number of shares of Substitute Common Stock as is equal to the Assigned Value multiplied by the number of shares of Common Stock for which the Option is then exercisable, divided by the Average Price. The exercise price of the Substitute Option per share of Substitute Common Stock shall then be equal to the Option Price multiplied by a fraction, the numerator of which shall be the number of shares of Common Stock for which the Option is then exercisable and the denominator of which shall be the number of shares of Substitute Common Stock for which the Substitute Option is exercisable.
 
(e) In no event, pursuant to any of the foregoing paragraphs, shall the Substitute Option be exercisable for more than 19.9% of the shares of Substitute Common Stock outstanding prior to exercise of the Substitute Option. In the event that the Substitute Option would be exercisable for more than 19.9% of the shares of Substitute Common Stock outstanding prior to exercise but for this clause (e), the issuer of the Substitute Option (the ”Substitute Option Issuer”) shall make a cash payment to Holder equal to the excess of (i) the value of the Substitute Option without giving effect to the limitation in this clause (e) over (ii) the value of the Substitute Option after giving effect to the limitation in this clause (e). This difference in value shall be determined by a nationally recognized investment banking firm selected by the Holder or the Owner, as the case may be, and reasonably acceptable to the Acquiring Corporation.
 
(f) Issuer shall not enter into any transaction described in subsection (a) of this Section 8 unless the Acquiring Corporation and any person that controls the Acquiring Corporation assume in writing all the obligations of Issuer hereunder.
 
9.  (a) At the request of the holder of the Substitute Option (the “Substitute Option Holder”), the Substitute Option Issuer shall repurchase the Substitute Option from the Substitute Option Holder at a price (the “Substitute Option Repurchase Price”) equal to the amount by which (i) the Highest Closing Price (as hereinafter defined) exceeds (ii) the exercise price of the Substitute Option, multiplied by the number of shares of Substitute Common Stock for which the Substitute Option may then be exercised, and at the request of the owner (the “Substitute Share Owner”) of shares of Substitute Common Stock (the “Substitute Shares”), the Substitute Option Issuer shall repurchase the Substitute Shares at a price (the “Substitute Share Repurchase Price”) equal to the Highest Closing Price multiplied by the number of Substitute Shares so designated. The term “Highest Closing Price” shall mean the highest closing price for shares of Substitute Common Stock within the six-month period immediately preceding the date the Substitute Option Holder gives notice of the required repurchase of the Substitute Option or the Substitute Share Owner gives notice of the required repurchase of the Substitute Shares, as applicable.
 
(b) The Substitute Option Holder and the Substitute Share Owner, as the case may be, may exercise its respective right to require the Substitute Option Issuer to repurchase the Substitute Option and the Substitute Shares pursuant to this Section 9 by surrendering for such purpose to the Substitute Option Issuer, at its principal office, the agreement for such Substitute Option (or, in the absence of such an agreement, a copy of this Agreement) and certificates for Substitute Shares accompanied by a written notice or notices stating that the Substitute Option Holder or the Substitute Share Owner, as the case may be, elects to require the Substitute Option Issuer to repurchase the Substitute Option and/or the Substitute Shares in accordance with the provisions of this Section 9. As promptly as practicable, and in any event within five business days after the surrender of the Substitute Option

and/or certificates representing Substitute Shares and the receipt of such notice or notices relating thereto, the Substitute Option Issuer shall deliver or cause to be delivered to the Substitute Option Holder the Substitute Option Repurchase Price and/or to the Substitute Share Owner the Substitute Share Repurchase Price therefor or, in either case, the portion thereof which the Substitute Option Issuer is not then prohibited under applicable law and regulation from so delivering.
 
(c) To the extent that the Substitute Option Issuer is prohibited under applicable law or regulation from repurchasing the Substitute Option and/or the Substitute Shares in part or in full, the Substitute Option Issuer following a request for repurchase pursuant to this Section 9 shall immediately so notify the Substitute Option Holder and/or the Substitute Share Owner and thereafter deliver or cause to be delivered, from time to time, to the Substitute Option Holder and/or the Substitute Share Owner, as appropriate, the portion of the Substitute Share Repurchase Price, respectively, which it is no longer prohibited from delivering, within five business days after the date on which the Substitute Option Issuer is no longer so prohibited; provided, however, that if the Substitute Option Issuer is at any time after delivery of a notice of repurchase pursuant to subsection (b) of this Section 9 prohibited under applicable law or regulation from delivering to the Substitute Option Holder and/or the Substitute Share Owner, as appropriate, the Substitute Option Repurchase Price and the Substitute Share Repurchase Price, respectively, in full (and the Substitute Option Issuer shall use its reasonable best efforts to obtain all required regulatory and legal approvals, in each case as promptly as practicable, in order to accomplish such repurchase), the Substitute Option Holder or Substitute Share Owner may revoke its notice of repurchase of the Substitute Option or the Substitute Shares either in whole or to the extent of the prohibition, whereupon, in the latter case, the Substitute Option Issuer shall promptly (i) deliver to the Substitute Option Holder or Substitute Share Owner, as appropriate, that portion of the Substitute Option Repurchase Price or the Substitute Share Repurchase Price that the Substitute Option Issuer is not prohibited from delivering; and (ii) deliver, as appropriate, either (A) to the Substitute Option Holder, a new Substitute Option evidencing the right of the Substitute Option Holder to purchase that number of shares of the Substitute Common Stock obtained by multiplying the number of shares of the Substitute Common Stock for which the surrendered Substitute Option was exercisable at the time of delivery of the notice of repurchase by a fraction, the numerator of which is the Substitute Option Repurchase Price less the portion thereof theretofore delivered to the Substitute Option Holder and the denominator of which is the Substitute Option Repurchase Price, or (B) to the Substitute Share Owner, a certificate for the Substitute Common Stock it is then so prohibited from repurchasing.
 
10.  The 90-day or 180-day periods for exercise of certain rights under Sections 2, 6, 7 and 13 shall be extended: (i) to the extent necessary to obtain all regulatory approvals for the exercise of such rights and for the expiration of all statutory waiting periods; (ii) to the extent necessary to avoid liability under Section 16(b) of the 1934 Act by reason of such exercise; and (3) when there exists an Order that prohibits or delays exercise of such right.
 
11.  Issuer hereby represents and warrants to Grantee as follows:
 
(a) Issuer has full corporate power and authority to execute and deliver this Agreement and to consummate the transactions contemplated hereby. The execution and delivery of this Agreement and the consummation of the transactions contemplated hereby have been duly and validly authorized by the Board of Directors of Issuer and no other corporate proceedings on the part of Issuer are necessary to authorize this Agreement or to consummate the transactions so contemplated. This Agreement has been duly and validly executed and delivered by Issuer.
 
(b) Issuer has taken all necessary corporate action to authorize and reserve and to permit it to issue, and at all times from the date hereof through the termination of this Agreement in accordance with its terms will have reserved for issuance upon the exercise of the Option, that number of shares of Common Stock equal to the maximum number of shares of Common Stock at any time and from time to time issuable hereunder, and all such shares, upon issuance pursuant hereto, will be duly authorized, validly issued, fully paid, nonassessable, and will be delivered free and clear of all claims, liens, encumbrance and security interests and not subject to any preemptive rights.
 
(c) The Board of Directors of Issuer has unanimously approved this Agreement and the transactions contemplated hereby (including by reserving shares for issuance of shares of Common Stock on exercise of the


C-8

Option) and taken any other action as required to render inapplicable to such agreement and transactions Section 203 of the Delaware General Corporation Law and, to the knowledge of Issuer, any similar Takeover Statutes.
 
12.  Grantee hereby represents and warrants to Issuer that:
 
(a) Grantee has all requisite corporate power and authority to enter into this Agreement and, subject to any approvals or consents referred to herein, to consummate the transactions contemplated hereby. The execution and delivery of this Agreement and the consummation of the transactions contemplated hereby have been duly authorized by all necessary corporate action on the part of Grantee. This Agreement has been duly executed and delivered by Grantee.
 
(b) The Option is not being, and any shares of Common Stock or other securities acquired by Grantee upon exercise of the Option will not be, acquired with a view to the public distribution thereof and will not be transferred or otherwise disposed of except in a transaction registered or exempt from registration under the 1933 Act.
 
13.  Neither of the parties hereto may assign any of its rights or obligations under this Agreement or the Option created hereunder to any other person, without the express written consent of the other party, except that in the event a Subsequent Triggering Event shall have occurred prior to an Exercise Termination Event, Grantee, subject to the express provisions hereof, may assign in whole or in part its rights and obligations hereunder within 180 days following such Subsequent Triggering Event; provided, however, that until the date 15 days following the date on which the Federal Reserve Board approves an application by Grantee or its transferee under the BHCA to acquire the shares of Common Stock subject to the Option, Grantee may not assign its rights under the Option except in (i) a widely dispersed public distribution, (ii) a private placement in which no one party acquires the right to purchase in excess of 2% of the voting shares of Issuer, (iii) an assignment to a single party (e.g., a broker or investment banker) for the purpose of conducting a widely dispersed public distribution on Grantee’s behalf, or (iv) any other manner approved by the Federal Reserve Board.
 
14.  Each of Grantee and Issuer will use its reasonable best efforts to make all filings with, and to obtain consents of, all third parties and governmental authorities necessary to the consummation of the transactions contemplated by this Agreement, including without limitation making application to list the shares of Common Stock issuable hereunder on the New York Stock Exchange upon official notice of issuance and applying to the Federal Reserve Board under the BHCA for approval to acquire the shares issuable hereunder, but Grantee shall not be obligated to apply to state banking authorities for approval to acquire the shares of Common Stock issuable hereunder until such time, if ever, as it deems appropriate to do so.
 
15.  (a) Grantee may, at any time during which Issuer would be required to repurchase the Option or any Option Shares pursuant to Section 7 upon proper request or notice, surrender the Option (together with any Option Shares issued to and then owned by Grantee) to Issuer in exchange for a cash fee equal to the Surrender Price (as defined below); provided, however, that Grantee may not exercise its rights pursuant to this Section 15 if Issuer has repurchased the Option (or any portion thereof) or any Option Shares pursuant to Section 7. The “Surrender Price” shall be equal to (i) $343,962,190, plus (ii) if applicable, the aggregate purchase price previously paid pursuant hereto by Grantee with respect to any Option Shares, minus (iii) if applicable, the sum of (A) the excess of (1) the net cash amounts, if any, received by Grantee pursuant to the arms’ length sale of Option Shares (or any other securities into which such Option Shares were converted or exchanged) to any party not affiliated with Grantee, over (2) the aggregate purchase price previously paid pursuant hereto by Grantee with respect to such Option Shares and (B) the net cash amounts, if any, received by Grantee pursuant to an arms’ length sale of a portion of the Option to any party not affiliated with Grantee.
 
(b) Grantee may exercise its right to surrender the Option and any Option Shares pursuant to this Section 15 by surrendering to Issuer, at its principal office, this Agreement together with certificates for Option Shares, if any, accompanied by a written notice stating (i) that Grantee elects to surrender the Option and Option Shares, if any, in accordance with the provisions of this Section 15 and (ii) the Surrender Price. The Surrender Price shall be payable in immediately available funds on or before the second business day following receipt of such notice by Issuer.

(d) Grantee shall have rights substantially identical to those set forth in paragraphs (a), (b) and (c) of this Section 15 with respect to the Substitute Option and the Substitute Option Issuer during any period in which the Substitute Option Issuer would be required to repurchase the Substitute Option pursuant to Section 9.
 
16.  (a) Notwithstanding any other provision of this Agreement, in no event shall the Grantee’s Total Profit (as hereinafter defined) exceed $393,099,645 and, if it otherwise would exceed such amount, the Grantee, at its sole election, shall either (i) reduce the number of shares of Common Stock subject to this Option, (ii) deliver to Issuer for cancellation Option Shares previously purchased by Grantee, (iii) pay cash to Issuer, or (iv) any combination thereof, so that Grantee’s actually realized Total Profit shall not exceed $393,099,645 after taking into account the foregoing actions.
 
(b) Notwithstanding any other provision of this Agreement, this Option may not be exercised for a number of shares as would, as of the date of exercise, result in a Notional Total Profit (as defined below) of more than $393,099,645; provided that nothing in this sentence shall restrict any exercise of the Option permitted hereby on any date subsequent to such initial date of exercise.
 
(c) As used herein, the term “Total Profit” shall mean the aggregate amount (before taxes) of the following: (i) the amount received by Grantee pursuant to Issuer’s repurchase of the Option (or any portion thereof) pursuant to Section 7, (ii) (x) the amount received by Grantee pursuant to Issuer’s repurchase of Option Shares pursuant to Section 7, less (y) the Grantee’s purchase price for such Option Shares, (iii) (x) the net cash amounts received by Grantee pursuant to the sale of Option Shares (or any other securities into which such Option Shares are converted or exchanged) to any unaffiliated party, less (y) the Grantee’s purchase price of such Option Shares, (iv) any amounts received by Grantee on the transfer of the Option (or any portion thereof) to any unaffiliated party, and (v) any amount equivalent to the foregoing with respect to the Substitute Option.

Board of Directors
Regions Financial Corporation
417 North 20th Street
Birmingham, AL 35203
 
Members of the Board of Directors:
 
AmSouth Bancorporation (“AmSouth”) and Regions Financial Corporation (“Regions”) propose to enter into an Agreement and Plan of Merger (the “Agreement”) pursuant to which AmSouth will be merged with and into Regions in a transaction (the “Merger”) in which each issued and outstanding share of AmSouth’s common stock, par value $0.01 per share (the “AmSouth Shares”), other than AmSouth Shares beneficially owned by Regions (other than shares held in a fiduciary or agency capacity or on behalf of third parties or as a result of debts previously contracted) and the AmSouth Shares held in the treasury of AmSouth, will be converted into the right to receive 0.7974 shares (the “Exchange Ratio”) of the common stock of Regions, par value $1.00 per share (the “Acquiror Shares”).
 
You have asked us whether, in our opinion, the Exchange Ratio is fair from a financial point of view to Regions.
 
In arriving at the opinion set forth below, we have, among other things:
 
(1) Reviewed certain publicly available business and financial information relating to AmSouth and Regions that we deemed to be relevant;
 
(2) Reviewed certain information, including financial forecasts, relating to the business, earnings, cash flow, assets, liabilities and prospects of AmSouth and Regions, as well as the amount and timing of the cost savings and related expenses and synergies expected to result from the Merger (the “Expected Synergies”) furnished to us by AmSouth and Regions, respectively;
 
(3) Conducted discussions with members of senior management and representatives of AmSouth and Regions concerning the matters described in clauses 1 and 2 above, as well as their respective businesses and prospects before and after giving effect to the Merger and the Expected Synergies;
 
(4) Reviewed the market prices and valuation multiples for the AmSouth Shares and the Regions Shares and compared them with those of certain publicly traded companies that we deemed to be relevant;
 
(5) Reviewed the results of operations of AmSouth and Regions and compared them with those of certain publicly traded companies that we deemed to be relevant;
 
(6) Compared the proposed financial terms of the Merger with the financial terms of certain other transactions that we deemed to be relevant;
 
(7) Participated in certain discussions and negotiations among representatives of AmSouth and Regions and their financial and legal advisors;
 
(8) Reviewed the potential pro forma impact of the Merger;
 
(9) Reviewed a draft dated May 23, 2006 of the Agreement;
 
(10) Reviewed drafts dated May 23, 2006 of the Stock Option Agreements between AmSouth and Regions; and
 
(11) Reviewed such other financial studies and analyses and took into account such other matters as we deemed necessary, including our assessment of general economic, market and monetary conditions.
 
In preparing our opinion, we have assumed and relied on the accuracy and completeness of all information supplied or otherwise made available to us, discussed with or reviewed by or for us, or publicly available, and we


D-1


Table of Contents

have not assumed any responsibility for independently verifying such information or undertaken an independent evaluation or appraisal of any of the assets or liabilities of AmSouth or Regions or been furnished with any such evaluation or appraisal, nor have we evaluated the solvency or fair value of AmSouth or Regions under any state or federal laws relating to bankruptcy, insolvency or similar matters. In addition, we have not assumed any obligation to conduct any physical inspection of the properties or facilities of AmSouth or Regions. With respect to the financial forecast information and the Expected Synergies furnished to or discussed with us by AmSouth or Regions, we have assumed that they have been reasonably prepared and reflect the best currently available estimates and judgment of AmSouth’s or Regions’s management as to the expected future financial performance of AmSouth or Regions, as the case may be, and the Expected Synergies. We have further assumed that the Merger will qualify as a tax-free reorganization for U.S. federal income tax purposes. We have also assumed that the final form of the Agreement and each ancillary agreement, as listed above, will be substantially similar to the last draft reviewed by us.
 
Our opinion is necessarily based upon market, economic and other conditions as they exist and can be evaluated on, and on the information made available to us as of, the date hereof. We have assumed that in the course of obtaining the necessary regulatory or other consents or approvals (contractual or otherwise) for the Merger, no restrictions, including any divestiture requirements or amendments or modifications, will be imposed that will have a material adverse effect on the contemplated benefits of the Merger.
 
In connection with the preparation of this opinion, we have not been authorized by Regions or the Board of Directors to solicit, nor have we solicited, third party indications of interest for the acquisition of all or any part of Regions.
 
We are acting as financial advisor to Regions in connection with the Merger and will receive a fee from Regions for our services, a significant portion of which is contingent upon the consummation of the Merger. In addition, Regions has agreed to indemnify us for certain liabilities arising out of our engagement. We have, in the past, provided financial advisory and financing services to Regions and AmSouth and may continue to do so and have received, and may receive, fees for the rendering of such services. In addition, in the ordinary course of our business, we may actively trade the AmSouth Shares and other securities of AmSouth, as well as the Regions Shares and other securities of Regions, for our own account and for the accounts of customers and, accordingly, may at any time hold a long or short position in such securities.
 
This opinion is for the use and benefit of the Board of Directors of Regions. Our opinion does not address the merits of the underlying decision by Regions to engage in the Merger and does not constitute a recommendation to any shareholder of Regions as to how such shareholder should vote on the proposed Merger or any matter related thereto. In addition, you have not asked us to address, and this opinion does not address, the fairness to, or any other consideration of, the holders of any class of securities, creditors or other constituencies of Regions. We are not expressing any opinion herein as to the prices at which the Regions Shares will trade following the announcement or consummation of the Merger.
 
On the basis of and subject to the foregoing, we are of the opinion that, as of the date hereof, the Exchange Ratio is fair from a financial point of view to Regions.
 
Very truly yours,

Ladies and Gentlemen:
 
You have requested our opinion as to the fairness from a financial point of view to the holders of the outstanding shares of common stock, par value $1.00 per share (the “Shares”), of AmSouth Bancorporation (the “Company”) of the exchange ratio of 0.7974 shares of common stock, par value $0.01 per share, of Regions Financial Corporation (“Regions”) to be received for each Share (the “Exchange Ratio”) pursuant to the Agreement and Plan of Merger, dated as of May 24, 2006 (the “Agreement”), by and between Regions and the Company.
 
Goldman, Sachs & Co. and its affiliates, as part of their investment banking business, are continually engaged in performing financial analyses with respect to businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and other transactions as well as for estate, corporate and other purposes. We have acted as financial advisor to the Company in connection with, and have participated in certain of the negotiations leading to, the transaction contemplated by the Agreement (the “Transaction”). We expect to receive fees for our services in connection with the Transaction, all of which are contingent upon consummation of the Transaction, and the Company has agreed to reimburse our expenses and indemnify us against certain liabilities arising out of our engagement. In addition, we have provided certain investment banking services to the Company from time to time including having acted as its financial advisor with respect to the sale of its credit card portfolio in November 2004, and the sale of its mutual fund operations in September 2005; and having acted as lead manager with respect to an offering of the Company’s fixed-rate, 5.20% coupon, 10-year subordinated notes offering (aggregate principal amount $500,000,000) in March 2003 and its fixed-rate, 4.85% coupon, 10-year subordinated notes offering (aggregate principal amount $450,000,000) in March 2005. We also may provide investment banking services to Regions in the future. In connection with the above-described investment banking services we have received, and may receive, compensation.
 
Goldman, Sachs & Co. is a full service securities firm engaged, either directly or through its affiliates, in securities trading, investment management, financial planning and benefits counseling, risk management, hedging, financing and brokerage activities for both companies and individuals. In the ordinary course of these activities, Goldman, Sachs & Co. and its affiliates may provide such services to the Company, Regions and their respective affiliates, may actively trade the debt and equity securities (or related derivative securities) of the Company and Regions for their own account and for the accounts of their customers and may at any time hold long and short positions of such securities.
 
In connection with this opinion, we have reviewed, among other things, the Agreement; annual reports to stockholders and Annual Reports on Form 10-K of the Company and Regions for the five fiscal years ended December 31, 2005; certain interim reports to stockholders and Quarterly Reports on Form 10-Q of the Company and Regions; certain other communications from the Company and Regions to their respective stockholders; certain research analyst estimates for the Company and Regions; and certain internal financial analyses and forecasts for the Company and Regions prepared by their respective managements, including certain cost savings and the impact of certain divestitures projected by the managements of the Company and Regions to result from the Transaction (the “Synergies”). We also have held discussions with members of the senior managements of the Company and Regions regarding their assessment of the strategic rationale for, and the potential benefits of, the Transaction and the past and current business operations, financial condition and future prospects of their respective companies. In addition, we have reviewed the reported price and trading activity for the Shares and Regions Common Stock, compared certain financial and stock market information for the Company and Regions with similar information for

certain other companies the securities of which are publicly traded, reviewed the financial terms of certain recent business combinations in the banking industry specifically and in other industries generally and performed such other studies and analyses, and considered such other factors, as we considered appropriate.
 
We have relied upon the accuracy and completeness of all of the financial, accounting, legal, tax and other information discussed with or reviewed by us and have assumed such accuracy and completeness for purposes of rendering this opinion. In that regard, we have assumed with your consent that the financial forecasts for the Company and Regions, including the Synergies, have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the Company and Regions. We also have assumed that all governmental, regulatory or other consents and approvals that are required in connection with the Transaction will be obtained without any adverse effect on the Company or Regions or on the expected benefits of the Transaction in any way meaningful to our analysis. We are not experts in the evaluation of loan and lease portfolios for purposes of assessing the adequacy of the allowances for losses with respect thereto and, accordingly, we have assumed that such allowances for losses are in the aggregate adequate to cover such losses. In addition, we have not reviewed individual credit files nor have we made an independent evaluation or appraisal of the assets and liabilities (including any contingent, derivative or off-balance-sheet assets and liabilities) of the Company, Regions or any of their respective subsidiaries and we have not been furnished with any such evaluation or appraisal.
 
Our opinion does not address the underlying business decision of the Company to engage in the Transaction nor are we expressing any opinion as to the prices at which shares of Regions Common Stock will trade at any time. Our advisory services and the opinion expressed herein are provided for the information and assistance of the Board of Directors of the Company in connection with its consideration of the Transaction and such opinion does not constitute a recommendation as to how any holder of Shares should vote with respect to the Transaction.
 
Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Exchange Ratio pursuant to the Agreement is fair from a financial point of view to the holders of Shares.
 
Very truly yours,

ITEM 20.   INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
The Regions certificate of incorporation provides that Regions shall indemnify its directors and officers to the fullest extent permitted by the Delaware General Corporation Law (the “DGCL”).
 
In addition, the Regions certificate of incorporation provides that no director shall be personally liable to Regions or Regions’ stockholders for monetary damages arising out of a breach of fiduciary duty, except for:
 
  •  any breach of the director’s duty of loyalty to Regions or Regions’ stockholders,
 
  •  acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law,
 
  •  breaches under Section 174 of the DGCL, or
 
  •  any transaction from which the director derived an improper personal benefit.
 
Section 145 of the DGCL provides that, subject to certain limitations in the case of suits brought by a corporation and derivative suits brought by a corporation’s stockholders in its name, a corporation may indemnify any person who is made a party to any suit or proceeding by reason of the fact that the person is or was a director, officer, employee or agent of the corporation against expenses, including attorneys’ fees, judgments, fines and amounts paid in settlement reasonably incurred by him in connection with the action, through, among other things, a majority vote of the directors who were not parties to the suit or proceeding, if the person (1) acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and (2) in a criminal proceeding, had no reasonable cause to believe his conduct was unlawful.
 
Section 145(b) of the DGCL provides that no such indemnification of directors, officers, employees or agents may be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation, unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

ITEM 22.   UNDERTAKINGS
 
(a) The undersigned registrant hereby undertakes to file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:
 
(1) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;
 
(2) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and
 
(3) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.
 
(b) The undersigned registrant hereby undertakes that, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
 
(c) The undersigned registrant hereby undertakes to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
 
(d) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the

II-2


Table of Contents

Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
 
(e) The undersigned registrant undertakes as follows:
 
(1) that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.
 
(2) that every prospectus (i) that is filed pursuant to paragraph (1) immediately preceding, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Securities Act of 1933 and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
 
(f) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.
 
(g) The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Item 4, 10(b), 11 or 13 of this form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.
 
(h) The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.
