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:

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 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.

(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.

(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 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. If so, the provisions of the AmSouth Stock Plans, including the respective terms of such plans, will be unchanged, except that (i) all Rights issued by Regions pursuant to the AmSouth Stock Plans following the Effective Time shall be Rights in respect of Regions Common Stock, (ii) all references to AmSouth (other than any references relating to a “change in control” of AmSouth) in each AmSouth Stock Plan and in each agreement evidencing any award thereunder shall be

deemed to refer to Regions, unless Regions determines otherwise, and (iii) the number of shares of Regions Common Stock available for future issuance pursuant to each AmSouth Stock Plan following the Effective Time (the “Available AmSouth Stock Plan Shares”) shall be equal to the number of shares of AmSouth Common Stock so available immediately prior to the Effective Time multiplied by the Exchange Ratio, rounded, if necessary, down to the nearest whole share of Regions Common Stock.

(e) Prior to the Effective Time, AmSouth shall take all necessary action for the adjustment of AmSouth Stock Options and AmSouth Stock-Based Awards under this Section 1.6. Regions shall reserve for future issuance a number of shares of Regions Common Stock at least equal to the number of shares of Regions Common Stock that will be subject to Regions Stock Options and Regions Stock-Based Awards as a result of the actions contemplated by this Section 1.6, plus the number of Available AmSouth Stock Plan Shares in the event that Regions maintains the AmSouth Stock Plans as contemplated by this Section 1.6. As soon as practicable following the Effective Time, Regions shall file a registration statement on Form S-8 or S-3, as the case dictates (or any successor form, or if Form S-8 or S-3 is not available, other appropriate forms), with respect to the shares of Regions Common Stock subject to such Regions Stock Options and Regions Stock-Based Awards (and the Available AmSouth Stock Plan Shares, as the case dictates) and shall maintain the effectiveness of such registration statement or registration statements (and maintain the current status of the prospectus or prospectuses contained therein) for so long as such Regions Stock Options and Regions Stock-Based Awards remain outstanding.

(f) AmSouth shall take such action as is necessary to provide that as of no later than three business days prior to the Closing Date no further shares of AmSouth Common Stock will be purchased under the AmSouth Direct Stock Purchase and Dividend Reinvestment Plan (the “AmSouth DRIP”); provided, that such cessation of further purchases following the Closing Date shall be conditioned upon the consummation of the Merger. Immediately prior to and effective as of the Effective Time and subject to the consummation of the Merger, AmSouth shall terminate the AmSouth DRIP.

1.7 Certificate of Incorporation and Bylaws. At the Effective Time, (1) the Regions Restated Certificate of Incorporation shall be the certificate of incorporation of the Surviving Corporation until thereafter amended in accordance with applicable law and (2) the Regions Bylaws, as amended in a manner consistent with Section 4.17, shall be the bylaws of the Surviving Corporation until thereafter amended in accordance with applicable law.

1.8 Effects of the Merger. At and after the Effective Time, the merger shall have the effects set forth in Section 259 of the DGCL.

1.9 Headquarters. At the Effective Time, the location of the corporate headquarters and of the principal executive offices of the Surviving Corporation shall be the City of Birmingham in the State of Alabama, United States of America.

(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 for fractional share interests (without interest), shall be delivered and paid with respect to each share represented by such New Certificate.

3.1 Disclosure Letters. Prior to the execution and delivery of this Agreement, each Party has delivered to the other Party a letter (its “Disclosure Letter”) setting forth, among other things, items the disclosure of which is necessary or appropriate either in response to an express disclosure requirement contained in a provision hereof or as an exception to one or more of such Party’s representations or warranties contained in Section 3.3 or to one or more of its covenants contained in Article 4; provided, that (i) no such item is required to be set forth in a Party’s Disclosure Letter as an exception to any representation or warranty of such Party if its absence would not result in the related representation or warranty being deemed untrue or incorrect under the standard established by Section 3.2, and (ii) the mere inclusion of an item in a Party’s Disclosure Letter as an exception to a representation or warranty shall not be deemed an admission by that Party that such item represents a material exception or fact, event or circumstance or that such item is reasonably likely to result in a Material Adverse Effect with respect to such Party. Any disclosures made with respect to a subsection of Section 3.3 shall be deemed to qualify (a) any subsections of Section 3.3 specifically referenced or cross-referenced and (b) other subsections of Section 3.3 to the extent it is clear (notwithstanding the absence of a specific cross reference) from a reading of the disclosure that such disclosure (i) applies to such other subsections and (ii) contains sufficient detail to enable a reasonable Person to recognize the relevance of such disclosure to such other subsections.

(b) The term “Material Adverse Effect,” as used with respect to a Party, means an effect which (i) is materially adverse to the business, properties, financial condition or results of operations of such Party and its Subsidiaries, taken as a whole, or (ii) materially

impairs the ability of such Party to consummate the Merger and the transactions contemplated hereby on a timely basis; provided that, in determining whether a Material Adverse Effect has occurred, there shall be excluded any effect to the extent attributable to or resulting from (A) any changes in Laws, regulations or interpretations of Laws or regulations generally affecting the banking, bank holding company or financial holding company businesses, (B) any change in GAAP or regulatory accounting requirements, generally affecting the banking, bank holding company or financial holding company businesses, (C) events, conditions or trends in economic, business or financial conditions generally affecting the banking, bank holding company or financial holding company businesses specifically, (D) changes in national or international political or social conditions including the engagement by the United States in hostilities, whether or not pursuant to the declaration of a national emergency or war, or the occurrence of any military or terrorist attack upon or within the United States, or any of its territories, possessions or diplomatic or consular offices or upon any military installation, equipment or personnel of the United States, or due to natural disasters, (E) the effects of the actions expressly permitted or required by this Agreement or that are taken with the prior informed written consent of the other Party in contemplation of the transactions contemplated hereby, and (F) the announcement of this Agreement and the transactions contemplated hereby.

It, and each of its Subsidiaries, has the requisite corporate power and authority to own, lease, and operate its properties and assets and to carry on its business as now conducted. It, and each of its Subsidiaries, is duly qualified or licensed to do business and (to the extent applicable) in good standing in the States of the United States and foreign jurisdictions where the character of its assets or the nature or conduct of its business requires it to be so qualified or licensed.

(i) It has the corporate power and authority necessary to execute, deliver, and perform its obligations under this Agreement and the Option Agreements and to consummate the transactions contemplated hereby and thereby. The execution, delivery, and performance of this Agreement and the Option Agreements, and the consummation of the transactions contemplated hereby and thereby, including the Merger, by it, have been duly and validly authorized by all necessary corporate action (including valid authorization and unanimous adoption of this Agreement and valid authorization of the Option Agreements, in each case, by its duly constituted Board of Directors), subject only to the receipt of

(A) in the case of AmSouth, the approval of this Agreement by the holders of a majority of the Outstanding shares of AmSouth Common Stock (the “AmSouth Stockholder Approval”), and (B) in the case of Regions, approval of this Agreement by the holders of a majority of the Outstanding shares of Regions Common Stock (the “Regions Stockholder Approval”). The amendment of the Regions Bylaws as set forth in Section 4.17 has been duly and validly authorized by all necessary corporate action (including valid authorization and unanimous adoption of a resolution, not to be withdrawn, providing for such Regions Bylaws amendment contingent on the Effective Time by Regions’s duly constituted Board of Directors).

The Regions Common Stock to be issued in the Merger, when issued, will be validly issued, fully paid and nonassessable, and no current or past stockholder of Regions will have any preemptive right or similar rights in respect thereof.

All Tax Returns required to be filed by or on behalf of it or any of its Subsidiaries have been timely filed or requests for extensions have been timely filed and any such extension has been granted and has not expired, and all such filed returns are complete and accurate in all material respects.

(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 disclosed in Section 3.3(k) of its Disclosure Letter, each of its ERISA Plans which is intended to be qualified under Section 401(a) of the Internal Revenue Code has received a favorable determination letter from the Internal Revenue Service covering all Tax Law changes prior to the Economic Growth and Tax Relief Reconciliation Act of 2001 and, to its knowledge, there are no circumstances likely to result in revocation of any such favorable determination letter. Except as 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.

(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.

(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 payments under any Compensation and Benefit Plans which would not be deductible under Section 280G of the Internal Revenue Code.

The Contracts of the type described in the preceding sentence, whether or not in effect as of the date of this Agreement, shall be deemed “Material Contracts” hereunder. With respect to each of its Material Contracts (A) that is reflected as an exhibit to any SEC Report, (B) would be required under Items 601(b)(4) and 601(b)(10) of Regulation S–K under the 1933 Act to be filed as an exhibit to any of its SEC Reports or (C) that is disclosed in its Disclosure Letter, or would be required to be so disclosed if in effect on the date of this Agreement: (w) each such Contract is in full force and effect; (x) neither it nor any of its Subsidiaries is in Default thereunder; (y) neither it nor any of its Subsidiaries has repudiated or waived any material provision of any such Contract; and (z) no other party to any such Contract is, to its knowledge, in Default in any material respect.

(ii) All interest rate swaps, caps, floors, option agreements, futures and forward contracts, and other similar risk management arrangements, whether entered into for its own account or for the account of one or more of its Subsidiaries or their respective customers, were entered into (A) in accordance with prudent business practices and all applicable Laws and (B) with counterparties believed to be financially responsible, and each of them is enforceable against it or its Subsidiaries in accordance with its terms (except in all cases as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, receivership, conservatorship, moratorium, or similar Laws affecting the enforcement of creditors’ rights generally and except that the availability of the equitable remedy of specific performance or injunctive relief is subject to the discretion of the court before which any proceeding may be brought), and is in full force and effect. 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. Its Financial Statements disclose the value of such agreements and arrangements on a mark-to-market basis in accordance with GAAP (including but not limited to Financial Accounting Statement 133) and, since March 31, 2006, there has not been a change in such value that, individually or in the aggregate, has resulted in a Material Adverse Effect on it.

(a) Subject to the terms and conditions of this Agreement, the Parties will use their reasonable best efforts to take, or cause to be taken, in good faith, all actions, and to do, or cause to be done, all things necessary, proper or desirable, or advisable under applicable Laws, including using its reasonable best efforts to lift or rescind any Order adversely affecting its ability to consummate the transactions contemplated hereby on a timely basis and to cause to be

satisfied the conditions in Article 5, to permit consummation of the Merger as promptly as practicable and otherwise to enable consummation of the transactions contemplated hereby, and each will cooperate fully with and furnish information to, the other Party to that end; provided that nothing contained herein shall preclude any Party from exercising its rights under this Agreement.

(b) AmSouth shall take all actions necessary or required to ensure that the entering into of this Agreement or of the AmSouth Option Agreement, and the consummation of the transactions contemplated hereby or thereby (individually or in conjunction with any other event), do not and will not result in (i) Regions or any Affiliate of Regions or any other Person becoming an “Acquiring Person” for purposes of the AmSouth Rights Plan or the occurrence of a “Separation Time” under the AmSouth Rights Plan or (ii) the ability of any Person to exercise any AmSouth Shareholder 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, distributable or unredeemable.

Regions agrees to use all

reasonable efforts, in which AmSouth shall reasonably cooperate as necessary, to cause the Registration Statement to be declared effective under the 1933 Act as promptly as practicable after filing thereof. The Parties agree to use all reasonable efforts to obtain all Consents required by the Securities Laws to carry out the transactions contemplated by this Agreement, and each Party agrees to furnish all information concerning it and the holders of its capital stock as may be reasonably requested in connection with any such action.

(b) Each Party agrees, as to itself and its Subsidiaries, that none of the information supplied or to be supplied by it for inclusion or incorporation by reference in (i) the Registration Statement will, at the time the Registration Statement and each amendment and supplement thereto, if any, become effective under the 1933 Act, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and (ii) the Joint Proxy Statement/Prospectus and any amendment or supplement thereto, at the date of mailing to stockholders and at the times of the meetings of Regions stockholders and AmSouth stockholders, will contain an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements, in light of the circumstances under which they were made, not misleading, or necessary to correct any statement in any earlier statement in the Joint Proxy Statement/Prospectus or any amendment or supplement thereto. Each Party further agrees that if it shall become aware prior to the Effective Time of any information furnished by it that would cause any of the statements in the Joint Proxy Statement/Prospectus or the Registration Statement to be false or misleading with respect to any material fact, or to omit to state any material fact necessary to make the statements therein not false or misleading, to promptly inform the other Party thereof and to take the necessary steps to correct the Joint Proxy Statement/Prospectus or the Registration Statement.

Each Party agrees that it will consult with the other Party with respect to the obtaining of all Regulatory Consents and other material Consents advisable to consummate the transactions contemplated by this Agreement and each Party will keep the other Party apprised of the status of material matters relating to completion of the transactions contemplated hereby, and will use reasonable efforts to include representatives of the other Party in any meetings or discussions with Governmental Authorities. All documents that the Parties or their respective Subsidiaries are responsible for filing with any Governmental Authority in connection with the transactions contemplated hereby (including to obtain Regulatory Consents) will comply as to form in all material respects with the provisions of applicable Law.

4.8 Notification of Certain Matters. Each Party will give prompt notice to the other Party (and subsequently keep the other Party informed on a current basis) upon its becoming aware of the occurrence or existence of any fact, event or circumstance that (a) is reasonably likely to result in any Material Adverse Effect on it, or (b) would cause or constitute a material breach of any of its representations, warranties, covenants, or agreements contained herein; provided, that any failure to give notice in accordance with the foregoing with respect to any breach shall not be deemed to constitute a violation of this Section 4.8 or the failure of any condition set forth in Sections 5.2(b) or 5.3(b) to be satisfied, or otherwise constitute a breach of this Agreement by the Party failing to give such notice, in each case unless the underlying breach would independently result in a failure of the conditions set forth in Section 5.2(a), 5.2(b), 5.3(a) or 5.3(b), to be satisfied or give rise to such termination right.

(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.

(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. Each of the Parties shall use its reasonable best efforts to enforce any existing confidentiality or standstill agreements to which it or any of its Subsidiaries is a party in accordance with the terms thereof.

(b) Nothing contained in this Agreement shall prevent a Party or its Board of Directors from complying with Rule 14d-9 and Rule 14e-2 under the 1934 Act with respect to an Acquisition Proposal; provided, that such Rules will in no way eliminate or modify the effect that any action pursuant to such Rules would otherwise have under this Agreement.

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.

(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 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.

(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 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.

(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. The provisions of this by-law shall also be considered an agreement of the Parties in this Agreement mutatis mutandis.

4.18 Change of Method. AmSouth and Regions shall be empowered, upon their mutual agreement and without additional approval of their respective Boards of Directors, at any time prior to the Effective Time, to change the method or structure of effecting the combination of AmSouth and Regions (including the provisions of Article 1), if and to the extent they both deem such change to be necessary, appropriate or desirable; provided, however, that no such change shall (i) alter or change the Exchange Ratio or the number of shares of Regions Common Stock received by AmSouth stockholders in exchange for each share of AmSouth Common Stock, (ii) adversely affect the Tax treatment of AmSouth’s stockholders or Regions’s stockholders pursuant to this Agreement, (iii) adversely affect the Tax treatment of AmSouth or Regions pursuant to this Agreement or (iv) materially impede or delay the consummation of the transactions contemplated by this Agreement in a timely manner. The Parties agree to reflect any such change in an appropriate amendment to this Agreement executed by both Parties in accordance with Section 7.6.

4.19 Restructuring Efforts. If either Regions or AmSouth shall have failed to obtain the requisite vote or votes of its Holders for the consummation of the transactions contemplated by this Agreement at a duly held meeting of its Holders or at any adjournment or postponement thereof, each of the parties shall in good faith use its reasonable best efforts to negotiate a restructuring of the transaction provided for herein (it being understood that neither Party shall have any obligation to alter or change the amount or kind of the merger consideration in a manner adverse to such party or its Holders) and/or to resubmit the transaction to their respective Holders for approval.

Title:		Chairman, President and Chief Executive Officer

AMSOUTH BANCORPORATION

By:		/s/ *C. Dowd Ritter*
Name:		C. Dowd Ritter
Title:		Chairman, President and Chief Executive Officer

I have been advised that as of the date hereof I may be deemed to be an “affiliate” of AmSouth Bancorporation, a Delaware corporation (“AmSouth”), as the term “affiliate” is defined for purposes of paragraphs (c) and (d) of Rule 145 (“Rule 145”) of the Securities and Exchange Commission (the “SEC”) under the Securities Act of 1933, as amended (including the rules and regulations thereunder, the “Act”). I have been further advised that pursuant to the terms of the Agreement and Plan of Merger, dated as of May 24, 2006 (the “Merger Agreement”), by and between AmSouth and Regions Financial Corporation, a Delaware corporation (“Regions”), AmSouth shall be merged with and into Regions (the “Merger”), and each share of common stock, par value $1.00 per share, of AmSouth (“AmSouth Common Stock”) shall be converted into the right to receive 0.7974 shares of common stock, par value $0.01 per share, of Regions (“Regions Common Stock”). I further understand that I may receive Regions Common Stock as a result of the exercise of AmSouth Stock Options or other similar Rights. All capitalized terms used in this letter but not defined herein shall have the meanings ascribed thereto in the Merger Agreement.

I hereby represent, warrant and covenant to Regions that, in the event I receive any Regions Common Stock as a result of the Merger:

1. The Regions Common Stock to be received by me as a result of the Merger or any securities which may be paid as a dividend or otherwise distributed thereon or with respect thereto or issued or delivered in exchange or substitution therefor, or any AmSouth Stock Option, Right or other interest (all such shares and securities being referred to herein as “Restricted Securities”) will be taken for my own account, and not for others, directly or indirectly, in whole or in part, and I will not make any sale, transfer or other disposition of Restricted Securities in violation of the Act.

2. I have carefully read this letter and discussed its requirements and other applicable limitations upon my ability to sell, transfer or otherwise dispose of Restricted Securities to the extent I believed necessary with my counsel or counsel for AmSouth.

3. I have been advised that the issuance of Regions Common Stock to me pursuant to the Merger will be registered with the SEC under the Act. However, I have also been advised that, since at the time the Merger will be submitted for a vote of the stockholders of AmSouth I may be deemed to have been an affiliate of AmSouth and the distribution by me of Restricted Securities has not been registered under the Act, I may not sell, transfer or otherwise dispose of Restricted Securities issued to me as a result of the Merger unless (i) such sale, transfer or other disposition has been registered under the Act, (ii) such sale, transfer or other disposition is made in conformity with the volume and other limitations of Rule 145, or (iii) in the opinion of counsel in form and substance reasonably acceptable to Regions, such sale, transfer or other disposition is otherwise exempt from registration under the Act.

4. I understand that Regions is under no obligation to register the sale, transfer or other disposition of Restricted Securities by me or on my behalf under the Act or to take any other action necessary in order to make compliance with an exemption from such registration available.

5. I also understand that stop transfer instructions will be given to Regions’s transfer agent with respect to Restricted Securities and that there will be placed on the certificates for Restricted Securities issued to me, or securities issued in substitution therefor, a legend stating in substance:

“The shares represented by this certificate (a) were issued in a transaction to which Rule 145 under the Securities Act of 1933, as amended, applies and (b) may not be sold, transferred or otherwise disposed of except or unless (1) covered by an effective registration statement under such Act, (2) in conformity with the volume and other limitations of Rule 145 under such Act, or (3) in accordance with a legal opinion in form and substance reasonably acceptable to Regions that such sale or transfer is otherwise exempt from the registration requirements of such Act.”

6. I understand and agree that, unless the transfer by me of my Restricted Securities has been registered under the Act or is a sale made in conformity with the provisions of Rule 145, Regions reserves the right, in its sole discretion, to put the following legend on the certificates issued to my transferee:

“The shares represented by this certificate have not been registered under the Securities Act of 1933 and were acquired from a person who received such shares in a transaction to which Rule 145 promulgated under the Securities Act of 1933 applies. The shares have been acquired by the holder not with a view to, or for resale in connection with, any distribution thereof within the meaning of the Securities Act of 1933 and may not be offered, sold, pledged or otherwise transferred except in accordance with an exemption from the registration requirements of the Securities Act of 1933.”

7. I understand and agree that the legends set forth in paragraphs (5) and (6) above shall be removed by delivery of substitute certificates without such legend, and/or the issuance of a letter to Regions’s transfer agent removing such stop transfer instructions, and the above restrictions on sale will cease to apply, if (A) one year (or such other period as may be required by Rule 145(d)(2) under the Act or any successor thereto) shall have elapsed from the Closing Date and the provisions of such Rule are then available to me; (B) if two years (or such other period as may be required by Rule 145(d)(3) under the Act or any successor thereto) shall have elapsed from the Effective Date and the provisions of such Rule are then available to me; or (C) I have delivered to Regions (i) a copy of a letter from the staff of the SEC, an opinion of counsel in form and substance reasonably satisfactory to Regions, or other evidence reasonably

satisfactory to Regions to the effect that such legend and/or stop transfer instructions are not required for purposes of the Act or (ii) evidence or representations reasonably satisfactory to Regions that the securities represented by such certificates are being or have been transferred in a transaction made in conformity with the provisions of Rule 145 or pursuant to an effective registration under the Act.

8. By executing this letter, without limiting or abrogating the agreements that I have made as set forth above, I am not admitting that I am an “affiliate” of AmSouth as described in the first paragraph of this letter or waiving any rights I may have to object to any claim that I am such an “affiliate” on or after the date of this letter.

9. I understand and agree that the foregoing provisions also apply to (i) my spouse, (ii) any relative of mine or my spouse occupying my home, (iii) any trust or estate in which I, my spouse or any such relative owns at least 10% beneficial interest or of which any of us serves as trustee, executor or in any similar capacity, and (iv) any corporate or other organization in which I, my spouse or any such relative owns at least 10% of any class of equity securities or of the equity interest.

10. I understand and agree that this Letter Agreement will terminate and be of no further force and effect if the Merger Agreement is terminated in accordance with its terms.

11. This Letter Agreement shall be governed by the Laws of the State of Delaware.
