TABLE OF CONTENTS

i

ABOUT THIS PROSPECTUS

     This document is called a prospectus and is part of a registration statement that we filed with the Securities and Exchange Commission, or SEC, using a “shelf” registration or continuous offering process. Under this shelf registration or continuous offering process, we may from time to time offer any combination of the securities described in this prospectus in one or more offerings up to a total dollar amount of $2,000,000,000.

     This prospectus provides you with a general description of the securities we may offer. Each time we sell securities, we will provide a prospectus supplement containing specific information about the terms of the securities being offered. A prospectus supplement may include a discussion of any risk factors or other special considerations applicable to those securities or to us. A prospectus supplement may also add, update or change information in this prospectus. If there is any inconsistency between the information in this prospectus and the applicable prospectus supplement, you should rely on the information in the prospectus supplement. You should read both this prospectus and any prospectus supplement together with additional information described under the heading “WHERE YOU CAN FIND MORE INFORMATION.”

     The registration statement containing this prospectus, including exhibits to the registration statement, provides additional information about us and the securities offered under this prospectus. The registration statement can be read at the SEC web site or at the SEC public reference room mentioned under the heading “WHERE YOU CAN FIND MORE INFORMATION.”

     When acquiring any securities discussed in this prospectus, you should rely only on the information we have provided in this prospectus and in the applicable prospectus supplement, including the information incorporated by reference. Neither we, nor any underwriters or agents, have authorized anyone to provide you with different information. We are not offering the securities in any state where the offer is prohibited. You should not assume that the information in this prospectus, any prospectus supplement, or any document incorporated by reference, is truthful or complete at any date other than the date of the particular document.

     We may sell securities to underwriters who will sell the securities to the public on terms fixed at the time of sale. In addition, the securities may be sold by us directly or through dealers or agents designated from time to time. If we, directly or through agents, solicit offers to purchase the securities, we reserve the sole right to accept and, together with any agents, to reject, in whole or in part, any of those offers.

     Any prospectus supplement will contain the names of the underwriters, dealers or agents, if any, together with the terms of offering, the compensation of those underwriters and the net proceeds to us. Any underwriters, dealers or agents participating in the offering may be deemed “underwriters” within the meaning of the Securities Act of 1933.

The information incorporated by reference is considered to be a part of this prospectus and should be read with the same care.

     We have not included or incorporated by reference in this prospectus any separate financial statements of Regions Financing Trust II, Regions Financing Trust III, or Regions Financing Trust IV, which we will refer to as the trusts. We do not believe that these financial statements would provide holders of preferred securities with any important information for the following reasons:

We do not expect that the trusts will be required to file any information with the SEC for as long as we continue to file our information with the SEC.

FORWARD-LOOKING STATEMENTS

     This prospectus and accompanying prospectus supplement contain or incorporate by reference certain forward-looking statements. The Private Securities Litigation Reform Act of 1995 (the “Act”) provides a “safe-harbor” for forward-looking statements which are identified as such and are accompanied by the identification of important factors that could cause actual results to differ materially from the forward-looking statements. For these statements, we, together with our subsidiaries, unless the context implies otherwise, claim the protection afforded by the safe harbor in the Act. Forward-looking statements are not based on historical information, but rather are related to future operations, strategies, financial results or other developments. Forward-looking statements are based on management’s expectations as well as certain assumptions and estimates made by, and information available to, management at the time the statements are made. Those statements are based on general assumptions and are subject to various risks, uncertainties, and other factors that may cause actual results to differ materially from the views, beliefs, and projections expressed in such statements. These risks, uncertainties and other factors include, but are not limited to those described below:

- 2 -

     The words “believe,” “expect,” “anticipate,” “project,” and similar expressions signify forward looking statements. You should not place undue reliance on any forward-looking statement, which speaks only as of the date made. You should refer to our periodic and current reports filed with the SEC for specific risks which could cause actual results to be significantly different from those expressed or implied by those forward- looking statements. We assume no obligation to update any forward-looking statements that are made from time to time.

REGIONS FINANCIAL CORPORATION

     Regions Financial Corporation (“Regions,” “we,” “us,” or “our”), is a financial holding company headquartered in Birmingham, Alabama which operates primarily within the southeastern United States. Regions’ operations consist of banking, brokerage and investment services, mortgage banking, insurance brokerage, credit life insurance, commercial accounts receivable factoring and specialty financing. At March 31, 2005, Regions had total consolidated assets of approximately $84.3 billion, total consolidated deposits of approximately $59.6 billion, and total consolidated stockholders’ equity of approximately $10.6 billion.

     Regions is a Delaware corporation, that on July 1, 2004, became the successor by merger to Union Planters Corporation and the former Regions Financial Corporation. Regions’ principal executive offices are located at 417 North 20^th Street, Birmingham, Alabama 35203, and its telephone number at such address is (205) 944-1300.

REGIONS TRUSTS

     Regions Financing Trust II, Regions Financing Trust III, and Regions Financing Trust IV are Delaware statutory trusts created by the certificates of trust that we filed with the Secretary of State of Delaware on January 26, 2001, as to Regions Financing Trust II, and November 20, 2001 as to Regions Financing Trust III and Regions Financing Trust IV. A statutory trust is a separate legal entity that can be formed for the purpose of holding property. For tax purposes, Regions Financing Trust II, Regions Financing Trust III, and Regions Financing Trust IV are all grantor trusts. A grantor trust is a trust that does not pay federal income tax if it is formed solely to facilitate direct investment in the assets of the trust and the trustee cannot change the investment. We created each of Regions Financing Trust II, Regions Financing Trust III, and Regions Financing Trust IV for the limited purpose of:

     The purchasers of the preferred securities that Regions Financing Trust II, Regions Financing Trust III, and Regions Financing Trust IV may issue will own all of the trusts’ preferred securities. We will own all of the common securities. Each trust is subject to the terms of its declaration of trust that we have executed as the depositor of the trust and which has also been executed by trustees of the trust. At the time a trust issues any preferred securities, the applicable declaration of trust will be amended and restated to set the terms of the preferred securities, which we will refer to as the amended declaration. The common securities will represent an aggregate liquidation amount equal to at least 3% of each trust’s total capitalization. The preferred securities will represent the remaining approximate 97% of each trust’s total capitalization. The terms of the common securities will also be contained in the amended declaration and the common securities will rank equally, and payments will be made ratably, with the preferred securities.

- 3 -

However, if there are certain continuing payment events of default under the junior subordinated debentures, our rights as holder of the common securities to distributions, liquidation, redemption and other payments from the trust will be subordinated to the rights to those payments of the holders of the preferred securities. Each trust will use the proceeds of the sale of the preferred securities and the common securities to invest in junior subordinated debentures that we will issue to the trust. The preferred securities will be guaranteed by us in the manner described later in this prospectus.

     The junior subordinated debentures and the interest we pay to Regions Financing Trust II, Regions Financing Trust III, and Regions Financing Trust IV on the junior subordinated debentures will be the trusts’ only assets and the interest we pay to Regions Financing Trust II, Regions Financing Trust III, and Regions Financing Trust IV on our junior subordinated debentures will be the only revenue of the trusts. Unless stated otherwise in the applicable prospectus supplement, the amended declarations will not permit the trusts to acquire any assets other than the junior subordinated debentures or to issue any securities other than the trust preferred securities and the common securities or to incur any other indebtedness.

     Each trust has a term of approximately 45 years but may be dissolved earlier under the terms of its amended declaration. The trustees of each trust will conduct the business and affairs of the trust. As holder of the common securities, we are entitled to appoint, remove, replace or increase or reduce the number of trustees. The amended declarations will govern the duties of the trustees. Most of the trustees will be employees, officers or affiliates of ours and will be referred to as administrative trustees. One trustee of each trust, the property trustee, will be a financial institution that is not affiliated with us and that has a minimum of combined capital and surplus of at least $50 million. The property trustee will act as indenture trustee for the purpose of compliance with the provisions of the Trust Indenture Act of 1939, or the Trust Indenture Act. Unless the property trustee has a principal place of business in the State of Delaware, and meets other legal requirements, we will appoint another trustee for each trust who meets these requirements to serve as the Delaware trustee. The trusts will be governed by the terms and provisions of their respective amended declaration entered into by and among us, as depositor, the Delaware trustee, the property trustee and the administrative trustees.

     We or any subsequent holder of the common securities will pay all fees and expenses related to the trusts and the offering of the preferred securities and will pay all ongoing costs and expenses of the trusts.

     The property trustee of each trust is Deutsche Bank Trust Company Americas, successor in interest to Bankers Trust Company Corporate Trust and Agency Service, 60 Wall Street, 27^th Floor, New York, New York 10005-2858, Attention: Global Debt Services. The Delaware trustee is Deutsche Bank Trust Company Delaware and its address in the state of Delaware is 1011 Centre Road, Floor 02, Wilmington, Delaware 19805-1266, Attn: Elizabeth Ferry. The principal place of business of each trust is c/o Regions Financial Corporation, 417 North 20th Street, Birmingham, Alabama 35203. The telephone number for each trust at that address is (205) 944-1300.

USE OF PROCEEDS

     Unless otherwise specified in the applicable prospectus supplement for any offering of securities, the net proceeds we receive from the sale of these securities will be used for general corporate purposes, which may include:

     Pending such use, we may temporarily invest net proceeds. We do not have any present plans, and are not engaged in any negotiations, for the use of any such proceeds, or the issuance of common stock, in any future acquisition. We will disclose any proposal to use the net proceeds from any offering of securities in connection with an acquisition in the prospectus supplement relating to such offering.

CONSOLIDATED RATIOS OF EARNINGS TO FIXED CHARGES

     Our consolidated ratio of earnings to fixed charges including our consolidated subsidiaries is computed by dividing earnings by fixed charges. The following table sets forth our consolidated ratios of earnings to fixed charges for the periods shown:

     For purposes of computing the ratio of earnings to fixed charges, earnings as adjusted consists of income (loss) before income taxes plus fixed charges. Fixed charges, excluding interest on deposits, consists of interest and debt expense, amortization of deferred debt costs, and the estimated interest portion of rent expense.

DESCRIPTION OF DEBT SECURITIES

General

     Unless stated otherwise in the applicable prospectus supplement, the following summary outlines the material terms of the senior debt securities and the subordinated debt securities (including our junior subordinated debentures), which we collectively refer to as the debt securities, that we may offer from time to time. The specific terms of any debt securities we may offer and the extent, if any, to which these general terms and provisions may or may not apply to the debt securities will be described in the applicable prospectus supplement relating to the particular series of debt securities.

     We will issue the senior debt securities under an indenture, which we will enter into with Deutsche Bank Trust Company Americas, as trustee. We will issue the subordinated debt securities under an indenture, which we have entered into with Deutsche Bank Trust Company Americas, as trustee. Any junior subordinated debentures we may issue will be sold exclusively to one or more of the trusts. The indentures are subject to and governed by the Trust Indenture Act, and we may supplement the indentures from time to time after we execute them. The following description of the debt securities may not be complete and is subject to and qualified in its entirety by reference to the form of either the senior or the subordinated indenture relating to the particular series of debt securities, each of which is an exhibit to the registration statement that contains this prospectus. Capitalized terms used but not defined in this description will have the meanings given to them in the indentures. Wherever we refer to particular sections or defined terms of the indentures, it is our intent that those sections or defined terms will be incorporated by reference in this prospectus.

     The senior indenture will prohibit us from disposing of, or permitting the issuance of, capital stock of specified subsidiaries under certain circumstances. See “— Certain Covenants — Covenants Relating to Senior Debt Securities.” The subordinated debt securities will be subordinated and junior to all “senior indebtedness” (which is defined below in “— Subordination”). The subordinated indenture will not prohibit us from disposing of the voting stock of any of our subsidiaries, including any voting stock of Regions Bank, our principal subsidiary bank.

     Since we are a holding company, our rights and the rights of our creditors, including holders of our debt securities, to participate in the assets of any of our subsidiaries upon the liquidation or reorganization of any of our subsidiaries will be subject to prior claims of the creditors of any such subsidiary, including in the case of our subsidiary banks, their depositors, except to the extent that we are a creditor of such subsidiary with recognized claims against the subsidiary. Claims on our subsidiaries by creditors other than us may include claims with respect to long-term debt and substantial obligations with respect to deposit liabilities, federal funds purchased, securities sold under repurchase agreements and other short-term borrowings.

Terms

     The debt securities will be our direct, unsecured obligations. The indebtedness represented by the senior debt securities will rank equally with all our other unsecured and unsubordinated debt, but will be subordinated to all of our existing and future secured indebtedness, if any, but only to the extent of the applicable collateral. The indebtedness represented by the subordinated debt

- 5 -

securities will rank junior in right of payment, under the terms contained in the subordinated indenture, and will be subject to our prior payment in full of our senior debt all as described under “— Subordination.”

     The indentures do not limit the aggregate principal amount of debt securities that we may issue; however, the amount of debt securities we offer will be limited to the amount described on the cover of this prospectus. We may issue the debt securities, in one or more series from time to time, as our board of directors may establish by resolution or as we may establish in one or more supplemental indentures. We may issue debt securities with terms different from those of debt securities we previously issued. We may issue debt securities of the same series at more than one time and, unless prohibited by the terms of the series, we may reopen a series for issuances of additional debt securities, without the consent of the holders of the outstanding debt securities of that series. The debt securities may be denominated and payable in foreign currencies or units based on or related to foreign currencies. Special United States federal income tax considerations applicable to any debt securities denominated in foreign currencies will be described in the applicable prospectus supplement.

     Each indenture provides that there may be more than one trustee under the indenture, each with respect to one or more series of the debt securities. Any trustee under an indenture may resign or be removed with respect to one or more series of the debt securities, and a successor trustee may be appointed to act with respect to that series. Upon prior written notice, a trustee may be removed by act of the holders of a majority in principal amount of the outstanding debt securities of the series with respect to which the trustee acts as trustee. If two or more persons are acting as trustee with respect to different series of debt securities, each trustee will be a trustee of a trust under the applicable indenture unrelated to the trust administered by any other trustee. Except as otherwise stated in this prospectus, any action described in this prospectus to be taken by each trustee may only be taken by the trustee with respect to the one or more series of debt securities for which it is trustee under the applicable indenture.

     You should refer to the applicable prospectus supplement relating to a particular series of debt securities for the specific terms of the debt securities, including, but not limited to:

- 6 -

- 7 -

     The debt securities of a series may provide for less than their entire principal amount to be payable if we accelerate the maturity of the debt securities as a result of the occurrence and continuation of an event of default. If this is the case, the debt securities would have what is referred to as “original issue discount.” Any special United States federal income tax, accounting and other considerations applicable to original issue discount securities will be described in the applicable prospectus supplement.

     We may issue debt securities of a series from time to time, with the principal amount payable on any principal payment date, or the amount of interest payable on any interest payment date, to be determined by reference to one or more currency exchange rates, commodity prices, equity indices or other factors. Holders of these debt securities may receive a principal amount on any principal payment date, or a payment of interest on any interest payment date, that is greater than or less than the amount of principal or interest otherwise payable on such dates, depending upon the value on the applicable dates of the applicable currency, commodity, equity index or other factors.

     Information as to the methods for determining the amount of principal or interest payable on any date, the currencies, commodities, equity indices or other factors to which the amount payable on such date is linked and certain additional tax considerations will be described in the applicable prospectus supplement.

     The indentures do not contain any provisions that afford holders of the debt securities protection in the event we engage in a transaction in which we incur or acquire a large amount of additional debt.

Denominations, Interest, Registration and Transfer

     Unless the applicable prospectus supplement states otherwise, debt securities we issue in registered form of any series will be issued in denominations of $1,000 and multiples of $1,000. Unless the applicable prospectus supplement states otherwise, debt securities we issue in bearer form will be issued in denominations of $5,000 and multiples of $5,000.

     Unless the applicable prospectus supplement states otherwise, the principal of, and any premium, Make-Whole Amount, or interest on, any series of debt securities will be payable in the currency designated in the prospectus supplement at the corporate trust office of the trustee, initially located at Deutsche Bank Trust Company Americas, 60 Wall Street, 27^th Floor, New York, New York 10005-2858, Attention: Global Debt Services. At our option, however, payment of interest may be made by check mailed to the address of the person entitled to the interest payment as it appears in the security register for the series or by wire transfer of funds to that person at an account maintained within the United States. We will have the right to require a holder of debt securities, in connection with any payment on such debt securities, to certify information to us or, in the absence of such certification, we will be entitled to rely on any legal presumption to enable us to determine our obligation, if any, to deduct or withhold taxes, assessments or governmental charges from such payment. We may at any time designate additional paying agents, remove any paying agents, or approve a change in the office through which any paying agent acts, except that we will be required to maintain a paying agent in each place of payment for any series. All monies we pay to a paying agent for the payment of principal of, or any premium, Make-Whole Amount, interest or Additional Amounts on, any debt security which remains unclaimed at the end of two years after the principal, premium or interest has become due and payable will be repaid to us, subject to any applicable law. After this time, the holder of the debt security will be able to look only to us for payment.

     Any interest we do not punctually pay on any interest payment date with respect to a debt security will be defaulted interest and will cease to be payable to the holder on the original regular record date and may either:

     If the defaulted interest is to be paid on a special record date, notice of the special record date will be mailed to each holder of such debt security not less than ten days before the special record date.

     Subject to certain limitations imposed on debt securities issued in book-entry form, debt securities of any series will be exchangeable for other debt securities of the same series and with the same total principal amount and authorized denomination upon surrender of the debt securities at the corporate trust office of the applicable trustee. In addition, subject to certain limitations imposed upon debt securities issued in book-entry form, the debt securities of any series may be surrendered for conversion, transfer or

- 8 -

exchange at the corporate trust office of the applicable trustee. Every debt security surrendered for conversion, transfer or exchange will be duly endorsed or accompanied by a written instrument of transfer. There will be no service charge on any transfer or exchange of debt securities, but we may require payment by holders to cover any tax or other governmental charge payable in connection with the transfer or exchange.

     If the applicable prospectus supplement refers to us designating a transfer agent (in addition to the applicable trustee) for any series of debt securities, we may at any time remove the transfer agent or approve a change in the location at which the transfer agent acts, except that we will be required to maintain a transfer agent in each place of payment for any series of debt securities. We may at any time designate additional transfer agents with respect to any series of debt securities.

     Neither we nor any trustee will be required to do any of the following:

Global Securities

     The debt securities in registered form of a series may be issued in the form of one or more fully registered global securities that will be deposited with a depositary or with a nominee for a depositary identified in the applicable prospectus supplement relating to the series and registered in the name of the depositary or its nominee. In this case, one or more registered global securities will be issued in a denomination or total denominations equal to the portion of the total principal amount of outstanding registered debt securities of the series to be represented by the registered global securities or securities. Unless and until it is wholly exchanged for debt securities in definitive registered form, a registered global security may not be transferred except as a whole by the depositary to its nominee or by a nominee to the depositary or another nominee, or by the depositary or its nominee to a successor of the depositary or the successor depositary’s nominee.

     The specific terms of the depositary arrangement with respect to any portion of a series of debt securities to be represented by a registered global security will be described in the applicable prospectus supplement. We anticipate that the following provisions will apply to all depositary arrangements.

     Ownership of beneficial interests in a registered global security will be limited to persons that have accounts with, or are participants of, the depositary for the registered global security or persons that may hold interests through participants. When we issue a registered global security, the depositary will credit, on its book-entry registration and transfer system, the participants’ accounts with the respective principal amounts of the debt securities represented by the registered global security owned by those participants. The accounts to be credited will be designated by any dealers, underwriters or agents participating in the distribution of the debt securities. Ownership of participants in a registered global security will be shown on, and the transfer of such ownership interests will be effected only through, records maintained by the depositary and ownership of persons who hold debt securities through participants will be reflected on the records of participants. Participants include securities brokers and dealers, banks and trust companies, clearing corporations and certain other organizations. Access to the depositary’s system is also available to others, such as banks, brokers, dealers and trust companies, that clear through or maintain a custodial relationship with a participant, either directly or indirectly, which we refer to as indirect participants. Persons who are not participants or indirect participants may beneficially own registered global securities held by the depositary only through participants or indirect participants. The laws of some states may require that certain purchasers of securities take physical delivery of such securities in definitive form. These laws may impair a person’s ability to own, transfer or pledge beneficial interests in a registered global security.

- 9 -

     So long as the depositary, or its nominee, is the registered owner of the global security, the depositary or such nominee, as the case may be, will be considered the sole owner or holder of the debt securities represented by the registered global security for all purposes under the applicable indenture. Except as set forth below, owners of beneficial interests in a registered global security will not be entitled to have the debt securities represented by the registered global security registered in their names, will not receive or be entitled to receive physical delivery of the debt securities in definitive form, and will not be considered the owners or holders thereof under the applicable indenture. Accordingly, each person owning a beneficial interest in a registered global security must rely on the procedures of the depositary and, if such person is not a participant, on the procedures of the participant and, if applicable, the indirect participant through which such person owns its interest, to exercise any rights of a holder under the applicable indenture. We understand that under existing industry practices, if we request any action of holders or if an owner of a beneficial interest in a registered global security desires to give or take any action which a holder is entitled to give or take under the applicable indenture, the depositary would authorize the participants holding the relevant beneficial interests to give or take the action, and the participants and, if applicable, indirect participants would authorize beneficial owners owning through the participants and, if applicable, indirect participants to give or take such action or would otherwise act upon the instructions of beneficial owners holding through them.

     Payments of principal of, and any premium, Make-Whole Amount, interest or Additional Amounts on, debt securities represented by a registered global security will be made to the depositary or its nominee, as the case may be, as the registered owner of the registered global security. None of us, the trustee or any other agent of ours or agent of the trustee will have any responsibility or liability for any aspect of the records relating to, or payments made on account of, beneficial ownership interests in the registered global security or for maintaining, supervising or reviewing any records relating to the beneficial ownership interests.

     We expect that once the depositary receives any payment of principal of, and any premium, Make-Whole Amount, interest or Additional Amounts on, a registered global security, the depositary will immediately credit participants’ accounts with payments in amounts proportionate to their respective beneficial interests in the registered global security as shown on the records of the depositary. We also expect that payments by participants or, if applicable, indirect participants to owners of beneficial interests in the registered global security held through the participants or, if applicable, indirect participants will be governed by standing customer instructions and customary practices, as is now the case with the securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of the participants or indirect participants as the case may be.

     Neither us, the trustee, any paying agent, nor the security registrar for the debt securities will have any responsibility or liability for any aspect of the records relating to, or payments made on account of, beneficial ownership interests in the registered global security for such debt securities or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

     If the depositary for debt securities notifies us that it is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Securities Exchange Act of 1934, or the Exchange Act, we have agreed to appoint a successor depositary. If we do not appoint a successor depositary registered as a clearing agency under the Exchange Act within 90 days after we become aware of the unwillingness, inability or ineligibility, we will issue debt securities in definitive form in exchange for the registered global security. In addition, we may at any time and in our sole discretion determine not to have any of the debt securities of a series represented by one or more registered global securities and, in such event, will issue debt securities of such series in a definitive form in exchange for all of the registered global security or securities representing the debt securities. Any debt securities issued in definitive form in exchange for a registered global security will be registered in such name or names as the depositary shall instruct the trustee. It is expected that such instructions will be based upon directions received by the depositary from participants with respect to ownership of beneficial interests in the registered global security.

     Debt securities in bearer form of a series may also be issued in the form of one or more global securities that will be deposited with a common depositary for the Euroclear System and Clearstream Banking, société anonyme Luxembourg (formerly known as Cedelbank), or with a nominee for such depositary identified in the applicable prospectus supplement. The specific terms and procedures, including the specific terms of the depositary arrangement and any specific procedures for the issuance of debt securities in definitive form in exchange for a bearer form global security, with respect to any portion of a series of debt securities to be represented by a bearer form global security will be described in the applicable prospectus supplement.

Merger, Consolidation or Sale

     We may consolidate with, or sell, lease or otherwise transfer all or substantially all of our assets to, or merge with or into, any other corporation or trust or entity provided that:

- 10 -

     Upon any such consolidation, merger, or sale, the successor corporation formed, or into which we are merged or to which we are sold, shall succeed to, and be substituted for, us under the indentures.

     This covenant would not apply to any recapitalization transaction, change of control of us or a transaction in which we incur a large amount of additional debt unless the transactions or change of control included a merger or consolidation or transfer of substantially all of our assets. Except as may be described in the applicable prospectus supplement, there are no covenants or other provisions in the indentures providing for a put or increased interest or that would otherwise afford holders of debt securities additional protection in the event of a recapitalization transaction, a change of control of us or a transaction in which we incur or acquire a large amount of additional debt.

Certain Covenants

     Existence. Except as permitted under “— Merger, Consolidation or Sale” above we will do or cause to be done all things necessary to preserve and keep our legal existence, rights and franchises in full force and effect; provided, however, that we will not be required to preserve any right or franchise if we determine that the preservation of that right or franchise is no longer desirable in the conduct of our business and that its loss is not disadvantageous in any material respect to the holders of any debt securities.

     Maintenance of Properties. We will cause all of our material properties used or useful in the conduct of our business or the business of any of our subsidiaries to be maintained and kept in good condition, repair and working order and supplied with all necessary equipment and we will cause to be made all necessary repairs, renewals, replacements, betterments and improvements for those properties, as we in our judgment believe is necessary so that we may carry on the business related to those properties properly and advantageously at all times; provided, however, that we will not be prevented from selling or otherwise disposing of our properties or the properties of our subsidiaries in the ordinary course of business.

     Payment of Taxes and Other Claims. We will pay or discharge, or cause to be paid or discharged, before they become delinquent,

provided, however, that we will not be required to pay or discharge or cause to be paid or discharged any tax, assessment, charge or claim the amount, applicability or validity of which is being contested in good faith by appropriate proceedings.

     Provision of Financial Information. Whether or not we are subject to Section 13 or 15(d) of the Exchange Act, we will, within 15 days of each of the respective dates by which we are or would be required to file annual reports, quarterly reports and other documents with the SEC pursuant to such Sections 13 and 15(d):

- 11 -

     Waiver of Certain Covenants. We may choose not to comply with any term, provision or condition of the foregoing covenants, or with certain other terms, provisions or conditions with respect to the debt securities of a series (except any such term, provision or condition which could not be amended without the consent of all holders of such series), if before or after the time for compliance with the covenant, term, provision or condition, the holders of at least a majority in principal amount of all outstanding debt securities of the series either waive compliance in that instance or generally waive compliance with that covenant or condition. Unless the holders expressly waive compliance with a covenant and the waiver has become effective, our obligations and the duties of the trustee in respect of the term, provision, or condition will remain in full force and effect.

     Covenants Relating to Senior Debt Securities. Except as described otherwise in the applicable prospectus supplement for any series of debt securities, we will not be permitted, pursuant to the covenants in the senior indenture, directly or indirectly, to do any of the following:

     The term “principal subsidiary bank” means any subsidiary bank, the consolidated assets of which constitute 50% or more of our consolidated assets. As of the date of this prospectus, we have only one principal subsidiary bank which is Regions Bank. The senior indenture does not restrict the ability of a principal subsidiary bank to sell or dispose of assets.

     The foregoing covenants in the senior indenture, however, do not prohibit any of the following:

- 12 -

     Covenants Relating to Junior Subordinated Debentures. In any subordinated indenture that governs the terms of the junior subordinated debentures we issue to a trust, in connection with the issuance of trust securities, we will covenant that, so long as any preferred securities of the trust remain outstanding, if there has occurred any event that would constitute an event of default under the applicable trust guarantee or amended declaration or if we have extended the interest payment periods of the junior subordinated debentures, we will not do any of the following:

     Additional Covenants. Any additional covenants with respect to any series of debt securities will be described in the applicable prospectus supplement.

Events of Default, Notice and Waiver

     Except as otherwise described in the applicable prospectus supplement, each of the following “Events of Default” set forth in the indentures will be applicable to each series of debt securities we may issue under those indentures:

- 13 -

     Unless otherwise set forth in the applicable terms of a series of debt securities, if there is a continuing event of default under an indenture with respect to outstanding debt securities of a series, then the applicable trustee or the holders of not less than 25% of the total principal amount of the outstanding debt securities of that series, voting as a single class, may declare immediately due and payable the principal amount or other amount as may be specified in the terms of the debt securities of and any premium or Make-Whole Amount on, all of the debt securities of that series. However, at any time after a declaration of acceleration with respect to any or all debt securities of a series then outstanding has been made, but before a judgment or decree for payment of the money due has been obtained by the applicable trustee, the holders of not less than a majority in principal amount of the outstanding debt securities of that series may cancel the acceleration if:

     Each indenture also provides that the holders of not less than a majority in principal amount of the applicable outstanding debt securities of any series may waive any past default with respect to those debt securities and its consequences, except a default consisting of:

     The trustee is generally required to give notice to the holders of the debt securities of each affected series within 90 days of a default of which the trustee has actual knowledge under the applicable indenture unless the default has been cured or waived. The trustee may withhold a notice of default unless the default relates to:

     Each indenture provides that no holder of debt securities of any series may institute a proceeding with respect to the indenture or for any remedy under the indenture, unless such holder has previously given notice to the applicable trustee of an event of default and the applicable trustee fails to act, for 60 days, after:

- 14 -

This provision will not prevent, however, any holder of debt securities from instituting suit for the enforcement of payment of the principal of, and any premium, Make-Whole Amount, interest or Additional Amounts on, debt securities at their respective due dates.

     Subject to provisions in each indenture relating to the trustee’s duties in case of default, the trustee is not under an obligation to exercise any of its rights or powers under any indenture at the request or direction of any holders of any series of debt securities then outstanding, unless the holders have offered to the trustee security or indemnity satisfactory to it. Subject to these provisions for the indemnification of the trustee, the holders of not less than a majority in principal amount of the applicable outstanding debt securities will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the applicable trustee, or of exercising any trust or power conferred upon the trustee. However, the trustee may refuse to follow any direction which is in conflict with any law or the applicable indenture, which may involve the trustee in personal liability or which may be unduly prejudicial to the holders of debt securities of the applicable series not joining in the direction.

     Within 120 days after the close of each fiscal year, we must deliver to each trustee a certificate, signed by one of several specified officers, stating such officer’s knowledge of our compliance with all the conditions and covenants under the applicable indenture and, in the event of any noncompliance, specifying such noncompliance and the nature and status of the noncompliance.

Modification of the Indenture

     Modification and amendment of an indenture may be made only with the consent of the holders of not less than a majority in principal amount of all outstanding debt securities issued under the indenture which are affected by the modification or amendment. However, no modification or amendment may, without the consent of the holder of each debt security affected, do any of the following:

     We and the relevant trustee may modify or amend an indenture, without the consent of any holder of debt securities, for any of the following purposes:

- 15 -

Subordination

     Unless otherwise indicated in the applicable prospectus supplement for a particular series of subordinated debt securities, the following subordinated indenture provisions will apply to the subordinated debt securities.

     The subordinated debt securities, including any junior subordinated debentures we issue any of the trusts, will be unsecured and subordinated in right of payment to all of our existing and future secured and senior debt. As a result, upon any distribution to our creditors in a liquidation, dissolution, bankruptcy, insolvency or reorganization, the payment of the principal of and interest on the subordinated debt securities will be subordinated to the extent provided in the subordinated indenture in right of payment to the prior payment in full of all our senior debt and our secured debt. Our obligation to make payments of the principal of and interest on the subordinated debt securities will not otherwise be affected.

     We may not make payments of principal or interest on the subordinated debt securities at any time we are in default on any payment with respect to our senior debt, or we have defaulted on any of our senior debt resulting in the acceleration of the maturity of the senior debt, or if there is a judicial proceeding pending with respect to our default on our senior debt and we have received notice of the default. We may resume payments on the subordinated debt securities when the default is cured or waived if the subordination provisions of the subordinated indenture will permit us to do so at that time. After we have paid all of our senior debt in full, holders of subordinated debt securities will still be subrogated to the rights of holders of our senior debt for the amount of distributions otherwise payable to holders of the subordinated debt securities until the subordinated debt securities are paid in full.

- 16 -

     If payment or distribution on account of the subordinated debt securities of any character or security, whether in cash, securities or other property, is received by a holder of any subordinated debt securities, including any applicable trustee, in contravention of any of the terms of the applicable indenture and before all our senior debt has been paid in full, that payment or distribution or security will be received in trust for the benefit of, and must be paid over or delivered and transferred to, holders of our senior debt at the time outstanding in accordance with the priorities then existing among those holders for application to the payment of all senior debt remaining unpaid to the extent necessary to pay all senior debt in full.

     Upon payment or distribution of assets to creditors upon insolvency, receivership, conservatorship, reorganization, readjustment of debt, marshalling of assets and liabilities or similar proceedings or any liquidation or winding up of or relating to our company as a whole, whether voluntary or involuntary, the holders of all senior debt securities will first be entitled to receive payment in full before holders of the outstanding subordinated debt securities will be entitled to receive any payment in respect of the principal of, or premium, if any, or interest on, the outstanding subordinated debt securities.

     After we have paid in full all sums we owe on our senior debt, the holders of the subordinated debt securities, if so issued, together with the holders of our obligations ranking on a parity with the subordinated debt securities, will be entitled to be paid from our remaining assets the amounts at the time due and owing on the subordinated debt securities and the other obligations. After we have paid in full all sums we owe on the subordinated debt securities, the holders of the junior subordinated debentures, together with the holders of our obligations ranking on a parity with the junior subordinated debentures, will be entitled to be paid from our remaining assets the amounts at the time due and owing on the junior subordinated debentures and the other obligations. We will make payment on the junior subordinated debentures before we make any payment or other distribution, whether in cash, property or otherwise, on account of any capital stock or obligations ranking junior to our junior subordinated debentures.

     By reason of this subordination, if we become insolvent, holders of senior debt, as well as certain of our general creditors, may receive more, and holders of subordinated debt securities (including junior subordinated debt securities) may receive less, than our other creditors, including holders of any of our senior debt securities. This subordination will not prevent the occurrence of any event of default on the subordinated debt securities.

     Senior debt is defined in the subordinated indenture as the principal, premium, if any, unpaid interest (including interest accruing on or after the filing of any petition in bankruptcy or for reorganization relating to us whether or not a claim for post-filing interest is allowed in such proceeding), fees, charges, expenses, reimbursement and indemnification obligations, and all other amounts payable under or in respect of the types of debt generally described below:

provided, however, that, in computing our debt, any particular debt will be excluded if:

- 17 -

     Senior debt will exclude the following:

     There is no limit on the amount of senior debt or other debt that we may incur in the subordinated indenture. At March 31, 2005, our senior debt aggregated approximately $9.9 billion.

Discharge, Defeasance and Covenant Defeasance

     Unless the terms of a series of debt securities provides otherwise, under each indenture, we may discharge certain obligations to holders of any series of debt securities that have not already been delivered to the applicable trustee for cancellation and that either have become due and payable or will become due and payable within one year (or are scheduled for redemption within one year). We can discharge these obligations by irrevocably depositing with the applicable trustee funds in such currency or currencies in which the debt securities are payable in an amount sufficient to pay the entire indebtedness on the debt securities including the principal of, and any premium, Make-Whole Amount, interest or Additional Amounts payable on, the debt securities to the date of the deposit, if the debt securities have become due and payable or to the stated maturity or redemption date, as the case may be.

     In addition, if the terms of the debt securities of a series permit us to do so, we may elect either of the following:

- 18 -

     If we choose to defease and discharge our obligations under the covenants, any failure to comply with the obligations imposed on us by the covenants will not constitute a default or an event of default with respect to the debt securities of that series. However, to make either election we must irrevocably deposit with the applicable trustee, in trust, an amount, in the currency or currencies in which the debt securities are payable, or in government obligations, or both, that will provide sufficient funds to pay the principal of, and any premium, Make-Whole Amount, interest or Additional Amounts on, the debt securities, and any mandatory sinking fund or analogous payments on the debt securities, on the relevant scheduled due dates or upon redemption.

     We may defease and discharge our obligations as described in the preceding paragraphs only if, among other things:

     Unless otherwise provided in the applicable prospectus supplement, if, after we have deposited funds and/or government obligations to effect defeasance or covenant defeasance with respect to debt securities of any series:

the indebtedness represented by the debt security shall be deemed to have been, and will be, fully discharged and satisfied through the payment of the principal of, and any premium, Make-Whole Amount, interest or Additional Amounts on, the debt security, as they become due, out of the proceeds yielded by converting the amount so deposited in respect of the debt security into the currency in which the debt security becomes payable as a result of the election or such cessation of usage based on the applicable market exchange rate.

     Unless otherwise defined in the applicable prospectus supplement, “conversion event” means the cessation of use of:

     Unless otherwise described in the applicable prospectus supplement, all payments of principal of, and any premium, Make-Whole Amount, interest or Additional Amounts on, any debt security that is payable in a foreign currency that ceases to be used by its government of issuance will be made in United States dollars.

     In the event we effect covenant defeasance with respect to any series of debt securities and the debt securities are declared due and payable because of the occurrence of any event of default other than:

- 19 -

then the amount on deposit with the trustee will still be sufficient to pay amounts due on the debt securities at the time of their stated maturity but may not be sufficient to pay amounts due on the debt securities at the time of the acceleration resulting from the event of default. In this case, we would remain liable to make payment of such amounts due at the time of acceleration.

     The applicable prospectus supplement may describe further provisions, if any, permitting defeasance or covenant defeasance, including any modifications to the provisions described above, with respect to a particular series of debt securities.

Conversion and Exchange Rights

     The terms on which debt securities of any series are convertible into or exchangeable for our common stock or other securities or property of ours will be set forth in the applicable prospectus supplement. These terms will include:

     The terms may also include calculations pursuant to which the number of shares of our common stock or other securities or property to be received by the holders of debt securities would be determined according to the market price of our common stock or other securities or property of ours as of a time stated in the prospectus supplement. The conversion exchange price of any debt securities of any series that is convertible into our common stock may be adjusted for any stock dividends, stock splits, reclassification, combinations or similar transactions, as described in the applicable prospectus supplement.

Redemption of Debt Securities

     If so specified in the applicable prospectus supplement, debt securities of any series may be wholly or partially redeemed at our option, at any time. The debt securities may also be subject to optional or mandatory redemption on terms and conditions described in the applicable prospectus supplement. Unless stated otherwise in the applicable prospectus supplement, our junior subordinated debentures may be redeemed in accordance with the description set forth in “Description of Trust Preferred Securities — Redemption.”

     From and after the time that notice has been given as provided in the indenture, if funds for the redemption of any debt securities called for redemption have been made available on the redemption date, the debt securities will cease to bear interest on the date fixed for redemption specified in the notice, and the only right of the holders of the debt securities will be to receive payment of the redemption price.

Governing Law

     The indentures are governed by, and will be construed in accordance with, the laws of the State of New York.

Concerning the Trustee

     We maintain banking relationships with Deutsche Bank Trust Company Americas and its affiliates in the ordinary course of business. These banking relationships include Deutsche Bank Trust Company Americas serving as trustee under the indentures involving our existing debt securities, serving as trustee in connection with trust preferred securities that were issued by our financing trust, Regions Financing Trust I, and providing us with general banking services. Upon the occurrence of an event of default or an event which, after notice or lapse of time or both, would become an event of default under a series of senior debt securities or subordinated debt securities, or upon the occurrence of a default under another indenture under which Deutsche Bank Trust Company Americas serves as trustee, the trustee may be deemed to have a conflicting interest with respect to the other debt securities as to which we are not in default for purposes of the Trust Indenture Act and, accordingly, may be required to resign as trustee under the applicable indenture. In that event, we would be required to appoint a successor trustee.

- 20 -

DESCRIPTION OF PREFERRED STOCK

     The following outlines some of the provisions of the preferred stock that we may offer from time to time. The specific terms of a series of preferred stock will be described in the applicable prospectus supplement relating to that series of preferred stock. The following description of the preferred stock and any description of preferred stock in a prospectus supplement may not be complete and is subject to and qualified in its entirety by reference to the certificate of designations relating to the particular series of preferred stock, which we will file with the SEC at or prior to the time of sale of the preferred stock.

General

     Under our amended and restated certificate of incorporation, our board of directors is authorized, without stockholder approval, to adopt resolutions providing for the issuance of up to 10,000,000 shares of preferred stock, par value $1.00 per share, in one or more series.

     For each series of preferred stock the board of directors may fix the voting powers, designations, preferences and rights, and qualifications, limitations or restrictions of the series. The board will fix these terms by resolution adopted before we issue any shares of the series of preferred stock.

     In addition, as described under “DESCRIPTION OF DEPOSITARY SHARES,” we may, instead of offering full shares of any series of preferred stock, offer depositary shares evidenced by depositary receipts, each representing a fraction of a share of the particular series of preferred stock issued and deposited with a depositary. The fraction of a share of preferred stock which each depositary share represents will be set forth in the prospectus supplement relating to the depositary shares.

     The prospectus supplement relating to the particular series of preferred stock will contain a description of the specific terms of that series as fixed by the board of directors, including, as applicable:

     When we issue and receive payment for shares of preferred stock, the shares will be fully paid and nonassessable, and for each share issued, a sum equal to the stated value will be credited to our preferred stock account. Unless otherwise specified in the prospectus supplement relating to a particular series of preferred stock, holders of preferred stock will not have any preemptive or subscription rights to acquire more of our stock, and each series of preferred stock will rank on a parity in all respects with each other series of preferred stock and prior to our common stock as to dividends and any distribution of our assets.

     The rights of holders of the preferred stock offered may be adversely affected by the rights of holders of any shares of preferred stock that may be issued in the future. Our board of directors may cause shares of preferred stock to be issued in public or private

- 21 -

     Since we are a holding company, our rights and the rights of the holders of our securities, including the holders of our preferred stock, to participate in the distribution of assets of any of our subsidiaries upon such subsidiary’s liquidation or recapitalization will be subject to the claims of such subsidiary’s general creditors except to the extent we are a creditor with recognized claims against such subsidiary.

Redemption

     If so specified in the applicable prospectus supplement, a series of preferred stock may be redeemable at any time, in whole or in part, at our option or the holder’s, and may be mandatorily redeemed.

     Any restriction on the repurchase or redemption by us of our preferred stock while we are in arrears in the payment of dividends will be described in the applicable prospectus supplement.

     Any partial redemptions of preferred stock will be made in a way that our board of directors decides is equitable.

     Unless we default in the payment of the redemption price, dividends will cease to accrue after the redemption date of shares of preferred stock called for redemption and all rights of holders of these shares will terminate except for the right to receive the redemption price.

Dividends

     Holders of each series of preferred stock will be entitled to receive cash dividends when, as and if declared by our board of directors out of funds legally available for dividends. The rates and dates of payment of dividends will be set forth in the applicable prospectus supplement relating to each series of preferred stock. Dividends will be payable to holders of record of preferred stock as they appear on our books on the record dates fixed by the board of directors. Dividends on any series of preferred stock may be cumulative or noncumulative.

     We may not declare, pay or set apart funds for payment of dividends on a particular series of preferred stock unless full dividends on any other series of preferred stock that ranks equally with or senior to the series of preferred stock have been paid or sufficient funds have been set apart for payment for either of the following:

     Partial dividends declared on shares of any series of preferred stock and other series of preferred stock ranking on an equal basis as to dividends will be declared pro rata. A pro rata declaration means that the ratio of dividends declared per share to accrued dividends per share will be the same for both series of preferred stock.

Liquidation Preference

     In the event of our liquidation, dissolution or winding-up, holders of each series of our preferred stock will have the right to receive distributions upon liquidation in the amount described in the applicable prospectus supplement relating to each series of preferred stock, plus an amount equal to any accrued and unpaid dividends. These distributions will be made before any distribution is made on the common stock or on any securities ranking junior to the preferred stock upon liquidation, dissolution or winding-up.

     If the liquidation amounts payable relating to the preferred stock of any series and any other securities ranking on a parity regarding liquidation rights are not paid in full, the holders of the preferred stock of these series and other securities will have the right to a ratable portion of our available assets, up to the full liquidation preference. Holders of these series of preferred stock or other securities will not be entitled to any other amounts from us after they have received their full liquidation preference.

- 22 -

Voting Rights

     The holders of shares of preferred stock will have no voting rights, except:

Transfer Agent and Registrar

     The transfer agent, registrar and dividend disbursement agent for the preferred stock will be stated in the applicable prospectus supplement. The registrar for shares of preferred stock will send notices to stockholders of any meetings at which holders of the preferred stock have the right to elect directors or to vote on any other matter.

DESCRIPTION OF DEPOSITARY SHARES

     The following briefly summarizes the provisions of the depositary shares and depositary receipts that we may issue from time to time and which would be important to holders of depositary receipts, other than pricing and related terms which will be disclosed in the applicable prospectus supplement. The prospectus supplement will also state whether any of the generalized provisions summarized below do not apply to the depositary shares or depositary receipts being offered. The following description and any description in a prospectus supplement may not be complete and is subject to, and qualified in its entirety by reference to the terms and provisions of the deposit agreement which we will file with the SEC in connection with an issuance of depositary shares.

Description of Depositary Shares

     We may offer depositary shares evidenced by depositary receipts. Each depositary receipt represents a fraction of a share of the particular series of preferred stock issued and deposited with a depositary. The fraction of a share of preferred stock which each depositary share represents will be set forth in the applicable prospectus supplement.

     We will deposit the shares of any series of preferred stock represented by depositary shares according to the provisions of a deposit agreement to be entered into between us and a bank or trust company which we will select as our preferred stock depositary. The depositary must have its principal office in the United States and have a combined capital and surplus of at least $50,000,000. We will name the depositary in the applicable prospectus supplement. Each owner of a depositary share will be entitled to all the rights and preferences of the underlying preferred stock in proportion to the applicable fraction of a share of preferred stock represented by the depositary share. These rights include dividend, voting, redemption, conversion and liquidation rights. The depositary will send the holders of depositary shares all reports and communications that we deliver to the depositary and which we are required to furnish to the holders of depositary shares.

Depositary Receipts

     The depositary shares will be evidenced by depositary receipts issued pursuant to the deposit agreement. Depositary receipts will be distributed to anyone who is buying the fractional shares of preferred stock in accordance with the terms of the applicable prospectus supplement.

     While definitive engraved depositary receipts (certificates) are being prepared, we may instruct the depositary to issue temporary depositary receipts, which will entitle holders to all the rights of the definitive depositary receipts and be substantially in the same form. The depositary will prepare definitive depositary receipts without unreasonable delay, and we will pay for the exchange of your temporary depositary receipts for definitive depositary receipts.

Withdrawal of Preferred Stock

     A holder of depositary shares may receive the number of whole shares of the series of preferred stock and any money or other property represented by the holder’s depositary receipts after surrendering the depositary receipts at the corporate trust office of the

- 23 -

Dividends and Other Distributions

     The depositary will pay to holders of depositary shares the cash dividends or other cash distributions it receives on preferred stock, after deducting its fees and expenses. Each holder will receive these distributions in proportion to the number of depositary shares owned by the holder. The depositary will distribute only whole United States dollars and cents. The depositary will add any fractional cents not distributed to the next sum received for distribution to record holders of depositary shares.

     In the event of a non-cash distribution, the depositary will distribute property to the record holders of depositary shares, unless the depositary determines that it is not feasible to make such a distribution. If this occurs, the depositary may, with our approval, sell the property and distribute the net proceeds from the sale to the holders.

Redemption of Depositary Shares

     If the series of preferred stock represented by depositary shares is subject to redemption, then we will give the necessary proceeds to the depositary. The depositary will then redeem the depositary shares using the funds they received from us for the preferred stock. The depositary will notify the record holders of the depositary shares to be redeemed not less than 30 nor more than 60 days before the date fixed for redemption at the holders’ addresses appearing in the depositary’s books. The redemption price per depositary share will be equal to the redemption price payable per share for the applicable series of the preferred stock and any other amounts per share payable with respect to the preferred stock multiplied by the fraction of a share of preferred stock represented by one depositary share. Whenever we redeem shares of preferred stock held by the depositary, the depositary will redeem the depositary shares representing the shares of preferred stock on the same day. If fewer than all the depositary shares of a series are to be redeemed, the depositary shares will be selected by lot or ratably as we may decide.

     After the date fixed for redemption, the depositary shares called for redemption will no longer be considered outstanding. Therefore, all rights of holders of the depositary shares will cease, except that the holders will still be entitled to receive any cash payable upon the redemption and any money or other property to which the holder was entitled at the time of redemption.

Voting the Preferred Stock

     Upon receipt of notice of any meeting at which the holders of preferred stock are entitled to vote, the depositary will notify holders of depositary shares of the upcoming vote and arrange to deliver our voting materials to the holders. The record date for determining holders of depositary shares that are entitled to vote will be the same as the record date for the preferred stock. The materials the holders will receive will (1) describe the matters to be voted on and (2) explain how the holders, on a certain date, may instruct the depositary to vote the shares of preferred stock underlying the depositary shares. For instructions to be valid, the depositary must receive them on or before the date specified. The depositary will try, as far as practical, to vote the shares as instructed by the holder. We will do anything the depositary asks us to do in order to enable it to vote as a holder has instructed. If any holder does not instruct the depositary how to vote the holder’s shares, the depositary will abstain from voting those shares.

Conversion or Exchange

     The depositary will convert or exchange all depositary shares on the same day that the preferred stock underlying the depositary shares is converted or exchanged. In order for the depositary to do so, we will need to deposit the other preferred stock, common stock or other securities into which the preferred stock is to be converted or for which it will be exchanged.

     The exchange or conversion rate per depositary share will be equal to:

- 24 -

     The depositary shares, as such, cannot be converted or exchanged into other preferred stock, common stock, securities of another issuer or any other securities or property of us. Nevertheless, if so specified in the applicable prospectus supplement, a holder of depositary shares may be able to surrender the depositary receipts to the depositary with written instructions asking the depositary to instruct us to convert or exchange the preferred stock represented by the depositary shares into other shares of our preferred stock or common stock or to exchange the preferred stock for securities of another issuer. If the depositary shares carry this right, we would agree that, upon the payment of any applicable fees, we will cause the conversion or exchange of the preferred stock using the same procedures as we use for the delivery of preferred stock. If a holder is only converting part of the depositary shares represented by a depositary receipt, new depositary receipts will be issued for any depositary shares that are not converted or exchanged.

Amendment and Termination of the Deposit Agreement

     We may agree with the depositary to amend the deposit agreement and the form of depositary receipt without consent of the holders at any time. However, if the amendment adds or increases fees or charges or prejudices an important right of holders, it will only become effective with the approval of holders of at least a majority of the affected depositary shares then outstanding. If an amendment becomes effective, holders are deemed to agree to the amendment and to be bound by the amended deposit agreement if they continue to hold their depositary receipts.

     The deposit agreement automatically terminates if:

     We may also terminate the deposit agreement at any time we wish. If we do so, the depositary will give notice of termination to the holders not less than 30 days before the termination date. Once depositary receipts are surrendered to the depositary, it will send to each holder the number of whole or fractional shares of the series of preferred stock underlying that holder’s depositary receipts.

Charges of Depositary and Expenses

     We will pay all transfer and other taxes and governmental charges in connection with the existence of the depositary arrangements. We will pay charges of the depositary for the initial deposit of the preferred stock and any redemption of the preferred stock. Holders of depositary shares will pay other transfer and other taxes and governmental charges and the charges that are expressly provided in the deposit agreement to be for the holders’ account.

Limitations on Our Obligations and Liability to Holders of Depositary Receipts

     The deposit agreement will limit our obligations and the obligations of the depositary. It will also limit our liability and the liability of the depositary as follows:

- 25 -

     In the deposit agreement, we will agree to indemnify the depositary under certain circumstances.

Resignation and Removal of Depositary

     The depositary may resign at any time by notifying us of its election to do so. In addition, we may remove the depositary at any time. The resignation or removal will take effect when we appoint a successor depositary and it accepts the appointment. We must appoint the successor depositary within 60 days after delivery of the notice of resignation or removal and the new depositary must be a bank or trust company having its principal office in the United States and having a combined capital and surplus of at least $50,000,000.

DESCRIPTION OF COMMON STOCK

     The following briefly summarizes the provisions of our amended and restated certificate of incorporation and by-laws that would be important to holders of our common stock. The following description may not be complete and is subject to, and qualified in its entirety by reference to, the terms and provisions of our amended and restated certificate of incorporation and bylaws which are exhibits to the registration statement which contains this prospectus.

General

     Under our amended and restated certificate of incorporation, we are authorized to issue a total of 1,500,000,000 shares of common stock having a par value of $0.01 per share. As of March 31, 2005, 463,228,863 shares of common stock were outstanding. All outstanding shares of common stock are fully paid and nonassessable. Our common stock is listed on The New York Stock Exchange.

     Holders of common stock do not have any conversion, redemption, preemptive or cumulative voting rights. In the event of our dissolution, liquidation or winding-up, common stockholders will share ratably in any assets remaining after all creditors are paid in full, including holders of our debt securities, and after the liquidation preference of holders of preferred stock has been satisfied.

Dividends

     Holders of common stock are entitled to participate equally in dividends when our board of directors declares dividends on shares of common stock out of funds legally available for dividends. The rights of holders of common stock to receive dividends are subject to the preferences of holders of preferred stock.

Voting Rights

     Holders of common stock are entitled to one vote for each share held of record on all matters voted on by stockholders, including the election of directors.

Liquidation Rights

     In the event of our liquidation, dissolution or winding-up, holders of common stock have the right to a ratable portion of assets remaining after satisfaction in full of the prior rights of our creditors, all liabilities, and the total liquidation preferences of any outstanding shares of preferred stock.

Certain Provisions That May Have an Anti-Takeover Effect

     Our amended and restated certificate of incorporation and by-laws, and certain portions of Delaware law, contain certain provisions that may have an anti-takeover effect.

- 26 -

     Board of Directors Classification. We have a staggered or classified board of directors. Our board of directors is divided into three classes with the members of each class serving a three-year term. The members of only one class of directors are elected at any annual meeting of our stockholders. It therefore takes at least two years to elect a majority of our directors.

     Business Combination. In addition to any other vote required by law, our amended and restated certificate of incorporation or agreement between us and any national securities exchange, the affirmative vote of the holders of at least 75% of the outstanding shares of our common stock entitled to vote in an election of the directors is required for any merger or consolidation with or into any other corporation, or any sale or lease of all or a substantial part of our assets to any other corporation person or other entity, in each case if, on the record date for the vote thereon, such corporation, person or entity is the beneficial owner, directly or indirectly, of 5% or more of the outstanding shares of the corporation entitled to vote in an election of directors. This supermajority vote of the holders of the outstanding shares of the corporation does not apply where:

     Special Meeting of Stockholders. Only our Chief Executive Officer, President, Secretary, or directors by resolution, may call a special meeting of our stockholders.

     Action of Stockholders Without a Meeting. Any action of our stockholders may be taken at a meeting only and may not be taken by written consent.

     Amendment of Certificate of Incorporation. For us to amend our amended and restated certificate of incorporation, Delaware law requires that our board of directors adopt a resolution setting forth any amendment, declare the advisability of the amendment and call a stockholders’ meeting to adopt the amendment. Generally, amendments to our amended and restated certificate of incorporation require the affirmative vote of majority of our outstanding stock. As described below, however, certain amendments to our amended and restated certificate of incorporation may require a supermajority vote.

     The vote of the holders of not less than 75% of outstanding shares of our capital stock entitled to vote in an election of directors, considered as a single class, is required to adopt any amendment to our amended and restated certificate of incorporation that relates to the provisions of our amended and restated certificate of incorporation that govern the following matters:

     The provisions described above may discourage attempts by others to acquire control of us without negotiation with our board of directors. This enhances our board of directors’ ability to attempt to promote the interests of all of our stockholders. However, to the extent that these provisions make us a less attractive takeover candidate, they may not always be in our best interests or in the best interests of our stockholders. None of these provisions is the result of any specific effort by a third party to accumulate our securities or to obtain control of us by means of merger, tender offer, solicitation in opposition to management or otherwise.

Transfer Agent and Registrar

     The transfer agent and registrar for shares of the common stock is EquiServe.

DESCRIPTION OF WARRANTS

General

     We may issue warrants to purchase senior debt securities, subordinated debt securities, preferred stock, depositary shares, common stock or any combination of these securities and these warrants may be issued independently or together with any underlying securities, and may be attached or separate from the underlying securities. We will issue each series of warrants under a separate warrant agreement to be entered into between us and a warrant agent. The warrant agent will act solely as our agent in connection with the warrants of such series and will not assume any obligation or relationship of agency for or with holders or beneficial owners of warrants. The following outlines some of the general terms and provisions of the warrants. Further terms of the warrants and the applicable warrant agreement will be stated in the applicable prospectus supplement. The following description and any description of the warrants in a prospectus supplement may not be complete and is subject to and qualified in its entirety by reference to the terms and provisions of the warrant agreement which we will file with the SEC in connection with an issuance of the warrants.

     The applicable prospectus supplement will describe the terms of any warrants, including the following:

- 28 -

     Warrant certificates may be exchanged for new warrant certificates of different denominations, and warrants may be exercised at the warrant agent’s corporate trust office or any other office indicated in the applicable prospectus supplement. Prior to the exercise of their warrants, holders of warrants exercisable for debt securities will not have any of the rights of holders of the debt securities purchasable upon such exercise and will not be entitled to payments of principal (or premium, if any) or interest, if any, on the debt securities purchasable upon such exercise. Prior to the exercise of their warrants, holders of warrants exercisable for shares of preferred stock or common stock or for depositary shares will not have any rights of holders of the preferred stock, common stock or depositary shares purchasable upon such exercise and will not be entitled to dividend payments, if any, or voting rights of the preferred stock, common stock or depositary shares purchasable upon such exercise.

Exercise of Warrants

     A warrant will entitle the holder to purchase for cash an amount of securities at an exercise price that will be stated in, or that will be determinable as described in, the applicable prospectus supplement. Warrants may be exercised at any time up to the close of business on the expiration date set forth in the applicable prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void.

     Warrants may be exercised as set forth in the applicable prospectus supplement. Upon receipt of payment and the warrant certificate properly completed and duly executed at the corporate trust office of the warrant agent or any other office indicated in the prospectus supplement, we will, as soon as practicable, forward the securities purchasable upon such exercise. If less than all of the warrants represented by such warrant certificate are exercised, a new warrant certificate will be issued for the remaining warrants.

Enforceability of Rights; Governing Law

     The holders of warrants, without the consent of the warrant agent, may, on their own behalf and for their own benefit, enforce, and may institute and maintain any suit, action or proceeding against us to enforce their rights to exercise and receive the securities purchasable upon exercise of their warrants. Unless otherwise stated in the applicable prospectus supplement, each issue of warrants and the applicable warrant agreement will be governed by the laws of the State of New York.

DESCRIPTION OF STOCK PURCHASE CONTRACTS

     We may issue stock purchase contracts, representing contracts obligating holders to purchase from or sell to us, and obligating us to purchase from or sell to the holders, a specified or variable number of shares of our capital stock at a future date or dates. The price per share of capital stock may be fixed at the time the stock purchase contracts are entered into or may be determined by reference to a specific formula contained in the stock purchase contracts. Any stock purchase contract may include anti-dilution provisions to adjust the number of shares to be delivered pursuant to such stock purchase contract upon the occurrence of certain events. We may issue the stock purchase contracts in such amounts and in as many distinct series as we wish.

     The stock purchase contracts may be entered into separately or as a part of units consisting of a stock purchase contract and a beneficial interest in senior debt securities, subordinated debt securities, preferred securities, debt obligations of third parties, including U.S. Treasury securities, other stock purchase contracts or shares of our capital stock securing the holders’ obligations under the stock purchase contracts to purchase or to sell the shares of our capital stock. The stock purchase contracts may require us to make periodic payments to holders of the stock purchase units, or vice versa, and such payments may be unsecured or prefunded and may be paid on a current or on a deferred basis. The stock purchase contracts may require holders to secure their obligations under those contracts in a specified manner.

     The applicable prospectus supplement may contain, where applicable, the following information about the stock purchase contracts issued under it:

- 29 -

     The applicable prospectus supplement will describe the terms of any stock purchase contracts. The preceding description and any description of stock purchase contracts in the applicable prospectus supplement does not purport to be complete and is subject to and is qualified in its entirety by reference to the stock purchase contract agreement and, if applicable, collateral arrangements and depositary arrangements relating to such stock purchase contracts.

DESCRIPTION OF UNITS

     We may issue units comprising one or more of the other securities described in this prospectus in any combination. Units may also include debt obligations of third parties, such as U.S. Treasury securities. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately at any time or at any time before a specified date.

     The applicable prospectus supplement may describe:

     The applicable prospectus supplement will describe the terms of any units. The preceding description and any description of units in the applicable prospectus supplement does not purport to be complete and is subject to and is qualified in its entirety by reference to the unit agreement and, if applicable, collateral arrangements and depositary arrangements relating to such units.

DESCRIPTION OF PREFERRED SECURITIES OF THE TRUSTS

General

     Unless stated otherwise in the applicable prospectus supplement, the following summary outlines the material terms and provisions of the preferred securities that the trusts may offer. The particular terms of any preferred securities a trust offers and the extent if any to which these general terms and provisions may or may not apply to the preferred securities will be described in the applicable prospectus supplement.

     Each trust will issue the preferred securities under an amended declaration, which we will enter into with the trustees. The amended declaration for each trust is subject to and governed by the Trust Indenture Act and Deutsche Bank Trust Company Americas, an independent trustee, will act as property trustee under each amended declaration for the purposes of compliance with the provisions of the Trust Indenture Act. The terms of the preferred securities will be those contained in the applicable amended declaration and those made part of the amended declaration by the Trust Indenture Act. The following summary may not be complete and is subject to and qualified in its entirety by reference to the form of amended declaration, which is an exhibit to the registration statement which contains this prospectus, and the Trust Indenture Act.

- 30 -

Terms

     Each amended declaration will provide that a trust may issue, from time to time, only one series of preferred securities and one series of common securities. The preferred securities will be offered to investors and the common securities will be held by us. The terms of the preferred securities, as a general matter, will mirror the terms of the junior subordinated debentures that we will issue to a trust in exchange for the proceeds of the sales of the preferred and common securities. If we fail to make a payment on the junior subordinated debentures, the trust holding those securities will not have sufficient funds to make related payments, including distributions, on its preferred securities.

     You should refer to the applicable prospectus supplement relating to the preferred securities for specific terms of the preferred securities, including, but not limited to:

     We will guarantee the preferred securities to the extent described below under “DESCRIPTION OF TRUST GUARANTEES.” Our guarantee, when taken together with our obligations under the junior subordinated debentures and the related subordinated indenture, and our obligations under the amended declaration, would provide a full and unconditional guarantee of amounts due on any preferred securities. Certain United States federal income tax considerations applicable to any offering of preferred securities will be described in the applicable prospectus supplement.

- 31 -

Liquidation Distribution Upon Dissolution

     We, as the holder of all the outstanding common securities of the trusts, or any subsequent holder of the common securities, have the right at any time to dissolve and liquidate the trusts and cause the junior subordinated debentures to be distributed to the holders of the preferred securities, and to us, as holder of the common securities.

     The Federal Reserve Board’s risk-based capital guidelines provide that redemptions of permanent equity or other capital instruments before stated maturity could have a significant impact on a bank holding company’s overall capital structure. Therefore, any organization considering a redemption of securities which make up a part of the organization’s regulatory capital should consult with the Federal Reserve Board if the redemption could have a material effect on the level or composition of the organization’s capital base. This consultation may not be necessary if the equity or capital instrument is redeemed with the proceeds of, or replaced by, a like amount of a similar or higher quality capital instrument and the Federal Reserve Board considers the organization’s capital position to be fully adequate after redemption. If we dissolve any of the trusts prior to the maturity date of the preferred securities and the Federal Reserve Board believes that the dissolution constitutes the redemption of capital instruments under its risk-based capital guidelines or policies, our dissolution of any of the trusts may be subject to prior approval of the Federal Reserve Board.

     Unless otherwise specified in an applicable prospectus supplement, each amended declaration states that each trust will be dissolved:

     Unless otherwise specified in an applicable prospectus supplement, in the event of a dissolution as described above other than in connection with redemption, after a trust satisfies all liabilities to its creditors as provided by applicable law, each holder of the preferred or common securities issued by that trust will be entitled to receive:

     If a trust cannot pay the full amount due on its preferred and common securities because it has insufficient assets available for payment, then the amounts payable by that trust on its preferred and common securities will be paid on a pro rata basis. However, if certain payment events of default under the subordinated indenture have occurred and are continuing with respect to any series of related junior subordinated debentures, the total amounts due on the preferred securities will be paid before any distribution on the common securities.

Events of Default

     The following will be events of default under each amended declaration:

- 32 -

     If an event of default with respect to a related series of junior subordinated debentures occurs and is continuing under the subordinated indenture, and the subordinated indenture trustee or the holders of not less than 25% in principal amount of the related junior subordinated debentures outstanding fail to declare the principal amount of all of such junior subordinated debentures to be immediately due and payable, the holders of at least 25% in aggregate liquidation amount of the outstanding preferred securities of the trust holding the junior subordinated debentures, will have the right to declare such principal amount immediately due and payable by providing written notice to us, the applicable property trustee and the subordinated indenture trustee.

     At any time after a declaration of acceleration has been made with respect to a related series of junior subordinated debentures and before a judgment or decree for payment of the money due has been obtained, the holders of a majority in liquidation amount of the affected preferred securities may rescind any declaration of acceleration with respect to the related junior subordinated debentures and its consequences:

     The holders of a majority in liquidation amount of the affected preferred securities may waive any past default under the subordinated debt securities indenture with respect to related junior subordinated debentures, other than a default in the payment of principal of, or any premium or interest on, any related junior subordinated debentures or a default with respect to a covenant or provision that cannot be amended or modified without the consent of the holder of each affected outstanding related junior subordinated debentures. In addition, the holders of at least a majority in liquidation amount of the affected preferred securities may waive any past default under the amended declaration.

     The holders of a majority in liquidation amount of the affected preferred securities shall have the right to direct the time, method and place of conducting any proceedings for any remedy available to the property trustee or to direct the exercise of any trust or power conferred on the property trustee under the amended declaration.

     A holder of preferred securities may institute a legal proceeding directly against us, without first instituting a legal proceeding against the property trustee or anyone else, for enforcement of payment to the holder of principal and any premium or interest on the related series of junior subordinated debentures having a principal amount equal to the aggregate liquidation amount of the preferred securities of the holder, if we fail to pay principal and any premium or interest on the related series of junior subordinated debentures when payable.

     We are required to furnish annually, to the property trustee for each trust, officers’ certificates to the effect that, to the best knowledge of the individuals providing the certificates, we and each trust are not in default under the applicable amended declaration or, if there has been a default, specifying the default and its status.

Consolidation, Merger or Amalgamation of the Trust

     No trust may merge with or into, amalgamate, consolidate, or be replaced by, or convey, transfer or lease its properties and assets substantially as an entirety to, any entity, except as described below or as described in “ — Liquidation Distribution Upon

- 33 -

     In addition, unless all of the holders of the preferred securities approve otherwise, no trust may consolidate, amalgamate or merge with or into, or be replaced by, or convey, transfer or lease its properties and assets substantially as an entirety to, any other entity, or permit any other entity to consolidate, amalgamate, merge with or into or replace it if the transaction would cause that trust or the successor entity to be taxable as a corporation or classified other than as a grantor trust for United States federal income tax purposes.

Voting Rights

     Unless otherwise specified in the applicable prospectus supplement, the holders of the preferred securities will have no voting rights except as discussed below and under “— Amendment to an Amended Declaration” and “DESCRIPTION OF TRUST GUARANTEES — Modification of the Trust Guarantee; Assignment” and as otherwise required by law.

     If any proposed amendment to an amended declaration provides for, or the trustees of a trust otherwise propose to effect:

- 34 -

then the holders of the affected preferred securities as a class will be entitled to vote on the amendment or proposal. In that case, the amendment or proposal will be effective only if approved by the holders of at least a majority in aggregate liquidation amount of the affected preferred securities.

     Without obtaining the prior approval of the holders of a majority in aggregate liquidation amount of the preferred securities issued by a trust, the trustees of that trust may not:

     However, if a consent under the subordinated indenture requires the consent of each affected holder of the related junior subordinated debentures, then the property trustee must obtain the prior consent of each holder of the preferred securities of the trust that holds the related junior subordinated debentures. In addition, before taking any of the foregoing actions, we will provide to the property trustee an opinion of counsel experienced in such matters to the effect that, as a result of such actions, the trust will not be taxable as a corporation or classified as other than a grantor trust for United States federal income tax purposes. The property trustee may not revoke any action previously authorized or approved by a vote of the holders of the preferred securities unless the holders of the preferred securities vote again on the same issue.

     The property trustee will notify all holders of preferred securities of a trust of any notice of default received from the subordinated indenture trustee with respect to the junior subordinated debentures held by that trust.

     Any required approval of the holders of preferred securities may be given at a meeting of the holders of the preferred securities convened for the purpose or pursuant to written consent. The applicable property trustee will cause a notice of any meeting at which holders of securities are entitled to vote to be given to each holder of record of the preferred securities at the holder’s registered address at least 15 days and not more than 90 days before the meeting.

     No vote or consent of the holders of the trust securities will be required for a trust to redeem and cancel its trust securities in accordance with its amended declaration.

     Notwithstanding that holders of the preferred securities are entitled to vote or consent under any of the circumstances described above, any of the preferred securities that are owned by us, any trustee or any affiliate of a trustee or ours will, for purposes of any vote or consent, be treated as if they were not outstanding. Preferred securities held by us or any of our affiliates may be exchanged for related junior subordinated debentures at the election of the holder.

Amendment to an Amended Declaration

     An amended declaration may be amended from time to time by us and the property trustee and the administrative trustees of each trust without the consent of the holders of the preferred securities of that trust to:

- 35 -

     Other amendments to an amended declaration may be made by us and the trustees of that trust upon approval of the holders of a majority in aggregate liquidation amount of the outstanding preferred securities of that trust and receipt by the trustees of an opinion of counsel to the effect that the amendment will not cause the trust to be taxable as a corporation, affect the treatment of the junior subordinated debentures held by the trust as indebtedness for United States federal income tax purposes or affect the trust’s exemption from the Investment Company Act of 1940.

     Notwithstanding the foregoing, without the consent of each affected holder of common or preferred securities of each trust, an amended declaration may not be amended to:

Redemption

     Unless stated otherwise in the applicable prospectus supplement, the following description summarizes our right to redeem our junior subordinated debentures and the preferred securities. We may redeem our junior subordinated debentures under certain circumstances. A redemption or repurchase of our junior subordinated debentures would cause a mandatory redemption of a proportionate amount of the preferred securities and common securities at the redemption price. The redemption price for each preferred security will equal the stated liquidation amount of the preferred security plus accumulated but unpaid distributions including any additional amounts to, but not including, the redemption date, plus the related amount of premium, if any, paid to the depositor upon the concurrent redemption of our junior subordinated debentures. Unless otherwise stated in the applicable prospectus supplement:

     Tax event means the receipt by us and the applicable trust of an opinion of counsel to the effect that, as a result of:

- 36 -

     If a tax event described in the first or third circumstances above has occurred and is continuing and the applicable trust holds all of our junior subordinated debentures, we will pay on our junior subordinated debentures any additional amounts as may be necessary in order that the amount of distributions then due and payable by the applicable trust on the outstanding preferred securities and common securities will not be reduced as a result of any additional taxes, duties and other governmental charges to which the applicable trust has become subject.

     Investment company event means the receipt by us and the applicable trust of an opinion of counsel to the effect that, as a result of the occurrence of a change in law or regulation or a written change, including any announced prospective change, in interpretation or application of law or regulation by any legislative body, court, governmental agency or regulatory authority, there is more than an insubstantial risk that the applicable trust is or will be considered an investment company that is required to be registered under the Investment Company Act of 1940, and this change becomes effective or would become effective on or after the date of the issuance of the preferred securities.

     Capital treatment event means the reasonable determination by us that, as a result of:

there is more than an insubstantial risk that we will not be entitled to treat an amount equal to the liquidation amount of the preferred securities as Tier 1 capital under the risk-based capital adequacy guidelines of the Federal Reserve Board.

     The Federal Reserve Board (“Board”) recently revised its risk-based capital guidelines to clarify the circumstances under which qualifying securities like the preferred securities may be included in Tier 1 capital. There are two sets of guidelines:

     As of March 31, 2005, 8.6% of our Tier 1 capital was composed of securities like the preferred securities, and as of March 31, 2005, we had 207,333 outstanding shares of preferred securities. Any redemption by us of our junior subordinated

- 37 -

debentures is subject to certain regulatory considerations. See “— Liquidation Distribution Upon Dissolution.” When the second set of guidelines take effect on April 1, 2009, outstanding shares of preferred securities issued by any of our real estate investment trust subsidiaries will be taken into account in determining compliance with the 25% limit.

Redemption Procedures

     Unless stated otherwise in the applicable prospectus supplement, the following description summarizes the procedures that will be followed if the preferred securities are to be redeemed. If we repay or redeem our junior subordinated debentures we must give the property trustee not less than 45 nor more than 60 days notice in order that it can redeem a proportionate amount of the preferred and common securities.

     Redemptions of the preferred securities will be made and the redemption price will be payable on each redemption date only to the extent that the trusts have funds available for the payment of the redemption price.

     If the trusts give the holders of preferred securities notice of redemption of any of the preferred securities held in a global security form, then, by 12:00 noon, Eastern Standard Time, on the redemption date, to the extent funds are available, in the case of preferred securities held in book-entry form, the property trustee will deposit irrevocably with the depositary, funds sufficient to pay the applicable redemption price and will give the depositary irrevocable instructions and authority to pay the redemption price to the holders of the preferred securities. With respect to preferred securities not held in a global security form, the property trustee, to the extent funds are available, will irrevocably deposit with the paying agent for the preferred securities funds sufficient to pay the applicable redemption price and will give the paying agent irrevocable instructions and authority to pay the redemption price to the holders of the preferred securities once the holders of the preferred securities surrender their certificates evidencing the preferred securities. Distributions payable on or prior to the redemption date for any preferred securities called for redemption will be payable on the distribution dates to holders of preferred securities on the relevant record dates.

     If the trusts give the holders of preferred securities notice of redemption and deposit the required funds, then on the date of that deposit all of the rights of the holders of the preferred securities with respect to their preferred securities called for redemption will cease, except their right to receive the redemption price and any distributions payable in respect of the preferred securities on or prior to the redemption date, but without interest. Preferred securities that the trusts redeem will cease to be outstanding. If any date fixed for redemption of preferred securities is not a business day, then the paying agent will pay the redemption price on the next succeeding day which is a business day, without any interest or other payment due to the delay. However, if the next business day falls in the next calendar year (or the next calendar month, in the case of Regions Financing Trust III and Regions Financing Trust IV), the paying agent will make the payment on the immediately preceding business day. In the event that payment of the redemption price for the preferred securities called for redemption is improperly withheld or refused and not paid either by the trusts or by us pursuant to the guarantee, distributions on the preferred securities will continue to accumulate at the then applicable rate, from the redemption date originally established by the trusts until the redemption price is actually paid. In that case, the actual payment date will be the date fixed for redemption for purposes of calculating the redemption price.

     Subject to applicable law, we or our affiliates may from time to time purchase outstanding preferred securities by tender, in the open market or by private agreement. We may resell these securities at any time that interest on our junior subordinated debentures is not being deferred, and there is no event of default or an event that could cause an event of default under the applicable indenture or an event of default under the guarantee.

     If less than all the preferred securities and common securities are to be redeemed on a redemption date, then the aggregate liquidation amount of preferred securities and common securities to be redeemed shall be allocated pro rata to the preferred securities and the common securities based upon the relative liquidation amounts of those classes. The particular preferred securities to be redeemed shall be selected by the property trustee in a manner that the property trustee deems fair, not more than 60 days prior to the redemption date or in accordance with the depositary’s customary procedures if the preferred securities are then held in global security form. The property trustee shall promptly notify the securities registrar for the preferred securities in writing of the preferred securities selected for redemption and, in the case of any preferred securities selected for partial redemption, the liquidation amount of the preferred securities to be redeemed. For all purposes of the amended declaration, unless the context otherwise requires, all provisions relating to the redemption of preferred securities relate, in the case of any preferred securities redeemed or to be redeemed only in part, to the portion of the aggregate liquidation amount of preferred securities which has been or is to be redeemed.

     If the preferred securities will be redeemed, the property trustee will mail to holders of such preferred securities a notice of redemption at the addresses as they appear on the securities register for the trusts at least 30 days but not more than 60 days before the redemption date. Unless we default in payment of the redemption price on our junior subordinated debentures on and after the

- 38 -

redemption date interest will cease to accrue on our junior subordinated debentures. Unless payment of the redemption price in respect of the preferred securities is withheld or refused and not paid either by the trusts or us pursuant to the guarantee, distributions will cease to accumulate on the preferred securities called for redemption.

Removal and Replacement of Trustees

     We, as the holder of each trust’s common securities may, upon prior written notice, remove or replace any of the administrative trustees and, unless an event of default has occurred and is continuing under the subordinated indenture, the property and Delaware trustee of the trust. If an event of default has occurred and is continuing under the subordinated indenture, only the holders of a majority in liquidation amount of the trust’s preferred securities may remove or replace the property trustee and Delaware trustee. The resignation or removal of any trustee will be effective only upon the acceptance of appointment by the successor trustee in accordance with the provisions of the applicable amended declaration. Unless stated otherwise in the applicable prospectus supplement, if a trustee is removed by the holders of the outstanding preferred securities or resigns, the successor trustee may be appointed by the holders of a majority in liquidation amount of the trust’s preferred securities. If a successor trustee has not been appointed by either holders of preferred securities or by the holder of the common securities, certain holders of preferred securities or common securities or the other trustees may petition a court in the state of Delaware to appoint a successor. Any Delaware trustee must meet the applicable requirements of Delaware law. Any property trustee must be a national- or state-chartered bank and have a combined capital and surplus of at least $50,000,000. No resignation or removal of a trustee and no appointment of a successor trustee shall be effective until the acceptance of appointment by the successor trustee in accordance with the provisions of the amended declaration. The holders of the preferred securities do not have any right to appoint, remove or replace the administrative trustees of the trusts. Only we, as holders of the common securities, have those rights.

Merger or Consolidation of Trustees

     Any entity into which a property trustee or the Delaware trustee may be merged or converted or with which it may be consolidated, or any entity resulting from any merger, conversion or consolidation to which the trustee shall be a party, or any entity succeeding to all or substantially all of the corporate trust business of the trustee, shall be the successor of the trustee under the applicable amended declaration; provided, however, that the entity shall be otherwise qualified and eligible. The succession will occur without the execution or filing of any paper or any further act on the part of the parties to the amended declaration.

Information Concerning the Property Trustee

     For matters relating to compliance with the Trust Indenture Act, the property trustee for each trust will have all of the duties and responsibilities of an indenture trustee under the Trust Indenture Act. The property trustee, other than during the occurrence and continuance of a default under an amended declaration, undertakes to perform only the duties as are specifically set forth in the amended declaration and, after a default, must use the same degree of care and skill as a prudent person would exercise or use in the conduct of his or her own affairs. The property trustee is under no obligation to exercise any of the powers given it by an amended declaration at the request of any holder of the preferred securities unless it is offered security or indemnity satisfactory to it against the costs, expenses and liabilities that it might incur. If the property trustee is required to decide between alternative courses of action, construe ambiguous provisions in an amended declaration or is unsure of the application of any provision of the amended declaration, and the matter is not one on which the holders of the preferred securities are entitled to vote, then the property trustee will deliver notice to us requesting written instructions as to the course of action to be taken and the property trustee will take or refrain from taking that action as instructed. If we do not provide these instructions within ten business days, then the property trustee will take such action as it deems advisable and in the best interests of the holders of the preferred and common securities. In this event, the property trustee will have no liability except for its own bad faith, negligence or willful misconduct.

     Deutsche Bank Trust Company Americas, which is the property trustee for each trust, also serves as the senior indenture trustee, the subordinated indenture trustee and the guarantee trustee under each trust guarantee described below. We and certain of our affiliates maintain banking relationships with affiliates of Deutsche Bank Trust Company Americas, which are described above under “DESCRIPTION OF DEBT SECURITIES — Concerning the Trustee.”

Miscellaneous

     The administrative trustees of each trust are authorized and directed to conduct the affairs of and to operate each trust in such a way so that:

- 39 -

     We, as holder of the common securities, and the trustees of each trust are authorized to take any action, so long as it is consistent with applicable law, the certificate of trust or amended declaration, that we and the trustees, determine to be necessary or desirable for the above purposes.

     Registered holders of the preferred securities have no preemptive or similar rights.

     A trust may not incur indebtedness or place a lien on any of its assets.

Governing Law

     Each amended declaration and the preferred securities will be governed by, and construed in accordance with, the laws of the State of Delaware, without regard to the conflict of laws provisions thereof, except for provisions relating to the immunities of the Property Trustee.

Description of the Expense Agreement

     We will execute an expense agreement at the same time that a trust issues the preferred securities. Under the expense agreement, we will irrevocably and unconditionally guarantee to each creditor of each trust the full amount of that trust’s costs, expenses and liabilities, other than the amounts owed to holders of its preferred and common securities pursuant to the terms of those securities. Third parties will be entitled to enforce the expense agreement. The expense agreement, once executed, will be filed with the SEC on Form 8-K or by a post-effective amendment to the registration statement of which this prospectus is a part.

DESCRIPTION OF TRUST GUARANTEES

     Unless stated otherwise in the applicable prospectus supplement, the following describes certain general terms and provisions of the trust guarantees which we will execute and deliver at the same time the trusts issue the preferred securities, for the benefit of the holders from time to time of the preferred securities. Each trust guarantee will be qualified as an indenture under the Trust Indenture Act, and Deutsche Bank Trust Company Americas, an independent trustee, will act as indenture trustee under each trust guarantee for the purposes of compliance with the provisions of the Trust Indenture Act. The terms of each trust guarantee will be those contained in each trust guarantee and those made part of each trust guarantee by the Trust Indenture Act. The following summary may not be complete and is subject to and qualified in its entirety by reference to the form of trust guarantee, which is an exhibit to the registration statement which contains this prospectus, and the Trust Indenture Act. Each trust guarantee will be held by the guarantee trustee of each trust for the benefit of the holders of the preferred securities.

General

     We will irrevocably and unconditionally agree to pay in full on a subordinated basis, to the extent set forth in the guarantee, the following payments or distributions with respect to preferred securities, to the holders of the preferred securities, as and when they become due regardless of any defense, right of set-off or counterclaim that a trust may have except for the defense of payment:

- 40 -

     Our obligation to make a payment under a trust guarantee may be satisfied by our direct payment of the required amounts to the holders of preferred securities to which the trust guarantee relates or by causing the applicable trust to pay the amounts to the holders.

Modification of the Trust Guarantee; Assignment

     Except with respect to any changes which do not adversely affect the rights of holders of preferred securities in any material respect (in which case no vote will be required), each trust guarantee may be amended only with the prior approval of the holders of not less than a majority in liquidation amount of the outstanding preferred securities to which the trust guarantee relates. The manner of obtaining the approval of holders of the preferred securities will be described in an accompanying prospectus supplement. All guarantees and agreements contained in each trust guarantee will bind our successors, assigns, receivers, trustees and representatives and will be for the benefit of the holders of the outstanding preferred securities to which the trust guarantee relates. Except in connection with a consolidation, merger or sale involving us that is permitted under the subordinated indenture and pursuant to which the assignee agrees in writing to perform our obligations under the guarantee, we may not assign our obligations under the guarantee.

Termination

     Each trust guarantee will terminate when any of the following has occurred:

     Each trust guarantee will continue to be effective or will be reinstated, as the case may be, if at any time any holder of preferred securities to which the trust guarantee relates must restore payment of any amounts paid on the preferred securities or under the trust guarantee.

Events of Default

     An event of default under a trust guarantee will occur if we fail to perform any of our payment obligations under a trust guarantee or we fail to perform any other obligation under a trust guarantee and the failure to perform such other obligation continues for 60 days.

     Each trust guarantee will constitute a guarantee of payment and not of collection. The holders of a majority in liquidation amount of the preferred securities to which the trust guarantee relates have the right to direct the time, method and place of conducting any proceeding for any remedy available to the guarantee trustee in respect of the trust guarantee or to direct the exercise of any trust or power conferred upon the guarantee trustee under the trust guarantee. If the guarantee trustee fails to enforce the trust guarantee, any holder of preferred securities to which the trust guarantee relates may institute a legal proceeding directly against us to enforce the holder’s rights under the trust guarantee, without first instituting a legal proceeding against the trust, the guarantee trustee or any one

- 41 -

else. If we do not make a guarantee payment, a holder of preferred securities may directly institute a proceeding against us for enforcement of the trust guarantee for such payment.

Status of the Trust Guarantees

     Each trust guarantee will be our general, irrevocable, and unsecured obligation and will rank subordinate and junior in right of payment, and will be subject to our prior payment in full of our senior debt and subordinated debt in the same manner as the junior subordinated debentures. The guarantee does not limit our ability to incur or issue other secured or unsecured senior or subordinated debt and we expect to incur, from time to time, additional senior and subordinated debt. Our obligations under the guarantee are effectively subordinated to all existing and future liabilities of any of our subsidiaries and their respective subsidiaries.

     The guarantee will constitute a guarantee of payment not of collection. A guarantee of payment entitles the guarantee trustee or the holder of the preferred securities to institute a legal proceeding against the trusts or any other person or entity. The guarantee will be held by the guarantee trustee for the benefit of the holders of the preferred securities. The guarantee will not be discharged except by paying the amounts required under the guarantee in full to the extent not paid by the trusts or distributing the junior subordinated debentures to you. The guarantee will apply only to the extent that the trusts have funds sufficient to make payments. If we do not make payments on the junior subordinated debentures held by the trusts, the trusts will not have the funds to pay any amounts payable in respect of the preferred securities.

     The terms of the preferred securities provide that each holder of preferred securities by acceptance of the preferred securities agrees to the subordination provisions and other terms of the trust guarantee relating to the subordination. As of March 31, 2005, we had approximately $9.9 billion that would rank senior to a trust guarantee.

Information Concerning the Guarantee Trustee

     The guarantee trustee, prior to the occurrence of a default with respect to a trust guarantee, undertakes to perform only those duties as are specifically contained in the trust guarantee and, after default, shall exercise the same degree of care as a prudent individual would exercise in the conduct of his or her own affairs. The guarantee trustee is under no obligation to exercise any of the powers vested in it by the applicable trust guarantee at the request of any holder of preferred securities to which the trust guarantee relates, unless it is offered indemnity satisfactory to it against the costs, expenses and liabilities which it might incur by exercising these powers; however the guarantee trustee will not be, upon the occurrence of an event of default under the applicable trust guarantee, relieved from exercising the rights and powers vested in it by such trust guarantee.

Governing Law

     The trust guarantees will be governed by, and construed in accordance with, the laws of the State of New York.

EFFECT OF OBLIGATIONS UNDER THE SUBORDINATED DEBT SECURITIES AND THE TRUST GUARANTEES

     As long as we may make payments of interest and any other payments when they are due on the junior subordinated debentures held by a particular trust, those payments will be sufficient to cover distributions and any other payments due on the trust securities issued by that trust because of the following factors:

- 42 -

     We will guarantee payments of distributions, to the extent the trust obligated to pay those distributions has sufficient funds available to make the payments due on the preferred securities, to the extent described under “DESCRIPTION OF TRUST GUARANTEES.” If we do not make interest payments on the junior subordinated debentures held by a trust, that trust will not have sufficient funds to pay distributions on the preferred securities. Each trust guarantee covers the payment of distributions and other payments on the preferred securities only if and to the extent that we have made a payment of interest or principal on the junior subordinated debentures held by the trust as its sole asset. However, we believe that the trust guarantees, when taken together with our obligations under the junior subordinated debentures and the subordinated indenture and our obligations under the amended declarations, including our obligations to pay the costs, expenses, debts and liabilities of the trusts, provide a full and unconditional guarantee of payment on the preferred securities.

     A holder of preferred securities may sue us to enforce its rights under the trust guarantee which relates to the holder’s preferred securities without first suing the guarantee trustee, the trust or any other person or entity.

PLAN OF DISTRIBUTION

     We and the trusts may offer and sell the securities to or through underwriters or dealers, and also may offer and sell the securities directly to other purchasers or through designated agents. Any underwriter or agent involved in the offer and sale of the securities will be named in the applicable prospectus supplement.

     Distribution of the securities may be effected from time to time in one or more transactions at a fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices. We and the trusts also may, from time to time, authorize underwriters acting as our agents to offer and sell the securities upon the terms and conditions set forth in any prospectus supplement.

     In connection with the sale of securities, underwriters may receive compensation from us or a trust or from purchasers of the securities, for whom they may act as agents, in the form of discounts, concessions or commissions. Underwriters may sell the securities to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for whom they may act as agents. Underwriters, dealers and agents that participate in the distribution of the securities may be deemed to be underwriters, and any discounts or commissions they receive from us or a trust, and any profit on the resale of the securities they realize may be deemed to be underwriting discounts and commissions under the Securities Act. Any such underwriter, dealer or agent will be identified, and any such compensation received will be described in the applicable prospectus supplement.

     Morgan Keegan & Company, Inc. (“Morgan Keegan”) is a member of the National Association of Securities Dealers, Inc. (the “NASD”) and is an affiliate of ours for purposes of the Conduct Rules of the NASD. In the event Morgan Keegan acts as an underwriter in connection with the offering of any securities under this registration statement, such offering will be conducted in accordance with the applicable sections of Rule 2720 of the Conduct Rules of the NASD or, in the case of the preferred securities of the trusts, Rule 2810 of the Conduct Rules of the NASD. Pursuant to such rules, no NASD member participating in any such offering will be permitted to execute a transaction in the securities in a discretionary account without the prior specific written approval of such member’s customer.

     The maximum underwriting compensation for any offering under the registration statement to which this prospectus relates may not exceed 8% of the offering proceeds.

     This prospectus, together with any applicable prospectus supplement, may also be used by Morgan Keegan or our other affiliates in connection with offers and sales of the securities in market-making transactions at negotiated prices at the time of sale. Morgan Keegan or our other affiliates may act as principal or agent in such transactions.

     Unless otherwise specified in the related prospectus supplement, each series of the securities will be a new issue with no established trading market, other than the common stock. Any common stock sold pursuant to a prospectus supplement will be listed on the New York Stock Exchange, NYSE, subject to official notice of issuance. We and the trusts may elect to list any of the other securities on an exchange, but are not obligated to do so. It is possible that one or more underwriters may make a market in a series of the securities, but will not be obligated to do so and may discontinue any market making at any time without notice. Therefore, no assurance can be given as to the liquidity of the trading market for the securities.

     If dealers are utilized in the sale of the securities, we and the trusts will sell the securities to the dealers as principals. The dealers may then resell the securities to the public at varying prices to be determined by such dealers at the time of resale. The names of the dealers and the terms of the transaction will be set forth in the applicable prospectus supplement.

     We and the trusts may enter into agreements with underwriters, dealers and agents who participate in the distribution of the securities which may entitle these persons to indemnification by us and the trusts against certain liabilities, including liabilities under the Securities Act, or to contribution with respect to payments which such underwriters, dealers or agents may be required to make in respect thereof. Any agreement in which we agree to indemnify underwriters, dealers and agents against civil liabilities will be described in the applicable prospectus supplement.

- 43 -

     We may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale transactions will be an underwriter and will be identified in the applicable prospectus supplement or a post-effective amendment.

     One or more firms, referred to as “remarketing firms,” may also offer or sell the securities, if the applicable prospectus supplement so indicates, in connection with a remarketing arrangement upon their purchase. Remarketing firms will act as principals for their own accounts or as agents for us. These remarketing firms will offer or sell the securities pursuant to the terms of the securities. The prospectus supplement will identify any remarketing firm and the terms of its agreement, if any, with us and will describe the remarketing firm’s compensation. Remarketing firms may be deemed to be underwriters in connection with the securities they remarket. Remarketing firms may be entitled to under agreements that may be entered into with us to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, and may be customers of, engage in transactions with or perform services for us in the ordinary course of business.

     Underwriters, dealers and agents may engage in transactions with, or perform services for, or be customers of ours in the ordinary course of business.

     If so indicated in the applicable prospectus supplement, we and/or a trust may authorize dealers or other persons acting as our or its agents to solicit offers by certain purchasers to purchase the securities from us or it at the public offering price stated in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on the date or dates stated in the prospectus supplement. Each delayed delivery contract will be for an amount not less than, and the aggregate principal amount or offering price of the securities sold pursuant to delayed delivery contracts will not be less nor more than, the respective amounts stated in the prospectus supplement. Institutions with whom delayed delivery contracts, when authorized, may be entered into include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and other institutions, but will in all cases be subject to approval by us and/or a trust. The obligations of any purchaser under any delayed delivery contract will not be subject to any conditions except that any related sale of offered securities to underwriters shall have occurred and the purchase by an institution of the securities covered by its delayed delivery contract shall not at the time of delivery be prohibited under the laws of any jurisdiction in the United States to which that institution is subject. The applicable prospectus supplement will state any commission payable for solicitation of these offers.

LEGAL MATTERS

     Unless otherwise indicated in the applicable prospectus supplement, the validity of the securities will be passed upon for us by R. Alan Deer, our General Counsel, or such other chief legal officer as we may designate from time to time, and Alston & Bird LLP, Washington, D.C. Mr. Deer beneficially owns shares of our common stock and options to acquire additional shares of our common stock. Certain United States federal income taxation matters will be passed upon for us by Alston & Bird LLP, Washington, D.C. Certain matters of Delaware law relating to the validity of the preferred securities will be passed upon for the trusts and us by Richards, Layton & Finger, P.A. Certain legal matters will be passed upon for any underwriters by Sidley Austin Brown & Wood LLP, unless otherwise specified in the applicable prospectus supplement.

PART II

INFORMATION NOT REQUIRED IN THE PROSPECTUS

Item 14. Other Expenses of Issuance and Distribution.

     The expenses in connection with the distribution of the securities are set forth in the following table. All amounts, except the Securities and Exchange Commission registration fee, are estimated.

Item 15. Indemnification of Directors and Officers.

     Section 145 of the Delaware General Corporation Law provides that a corporation may indemnify its directors and officers, as well as other employees and individuals, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement in connection with specified actions, suits or proceedings, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation – a “derivative action”), if they acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe their conduct was unlawful. A similar standard is applicable in the case of derivative actions, except that indemnification only extends to expenses (including attorneys’ fees) actually and reasonably incurred in connection with the defense or settlement of such action, and the statute requires court approval before there can be any indemnification where the person seeking indemnification has been found liable to the corporation. The statute provides that it is not exclusive of other rights to which those seeking indemnification may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise.

     Article Tenth of Regions’ Amended and Restated Certificate of Incorporation provides for the indemnification of Regions’ directors and officers as set forth below:

“TENTH.

     (1) The corporation shall indemnify its officers, directors, employees and agents to the fullest extent permitted by law.

     (2) No director of the corporation shall be personally liable to the corporation or its stockholders for monetary damages, for breach of fiduciary duty as a director, except for liability (i) for any breach of the director’s duty of loyalty to the corporation or its stockholders; (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; (iii) under Section 174 of the Delaware General Corporation Law; or (iv) for any transaction from which the director derived an improper personal benefit.”

     Article V, Section 11, of Regions’ By-laws provides for the indemnification of Regions’ directors and officers as set forth below:

“SECTION 11
INDEMNIFICATION OF OFFICERS, DIRECTORS, EMPLOYEES, AGENTS AND
FIDUCIARIES; INSURANCE:

     (A) The Corporation shall indemnify, in accordance with and to the fullest extent permitted by law, any person made or threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that such person is or was a Director, Advisory Director, officer,

II - 1

employee, agent or fiduciary of the Corporation or any constituent corporation absorbed in a consolidation or merger, or serves as such with another corporation, or with a partnership, joint venture, trust or other enterprise at the request of the Corporation or any such constituent corporation.

     (B) The indemnification provided by this Section 11 shall not be deemed exclusive of and shall be in addition to any other rights (whether created prior or subsequent to the adoption of these By-Laws) to which those indemnified may be entitled under any statute, rule of law, articles of incorporation, by-law, agreement, vote of stockholders or disinterested Directors or otherwise, both as to action in their official capacity and as to action in another capacity and as to action in another capacity while holding such office, and shall continue as to a person who has ceased to be a Director, employee or agent of the Corporation, and shall inure to the benefit of the heirs, executors and administrators of such a person.

     (C) By action of the Board of Directors notwithstanding any interest of the Directors in such action, the Corporation may purchase and maintain insurance in such amounts as the Board of Directors deems appropriate on behalf of any person who is or was a Director, officer, employee, agent or fiduciary of the Corporation, or is or was serving at the request of the Corporation as a Director, officer, employee, agent or fiduciary of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against him and incurred by him in any such capacity, or arising out of his status as such, whether or not the Corporation shall have the power to indemnify him against such liability under the provisions of this Section 11.”

Item 16. Exhibits

Item 17. Undertakings

     (a) The undersigned Registrants hereby undertake:

     (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

     (i) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

     (ii) 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 the 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 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;

     (iii) 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;

provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the registration statement is on Form S-3, Form S-8 or Form F-3 and the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement.

     (2) 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.

     (3) 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.

     (b) The undersigned Registrants hereby undertake 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 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.

     (c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrants pursuant to the foregoing provisions, or otherwise, the Registrants have 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 a Registrant of expenses incurred or paid by a director, officer or controlling person of a Registrant in the successful defense of any action, suit or proceeding) is asserted against a Registrant by such director, officer or controlling person in connection with the securities being registered, a 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 Act and will be governed by the final adjudication of such issue.
